Ensure the JSON is valid. \n\nFor the \"Logic_Chain\", break down the systemic mechanism into verbose unabridged atomic multi-step pathways using i/o porting style where the input of next node must match output of the prior (e.g., A -> B, B->C, C->D). Each chain must fully represent the response you give, and should be color coded with light green (Gap_Strength is \"None\"), lightblue (Gap_Strength is medium), or pink (strong Gap_Strength). Logic_Chain MUST be a JSON array of objects. Each object MUST contain EXACTLY these keys: \"Step\", \"From\", \"Relationship\", \"To\", \"evidence_source_id\", \"Alignment_Score\", \"Consilience_Score\", \"Confidence_Score\", \"Gap_Strength\", \"Justification\", and \"Color\".

Do not alter a single character, do not paraphrase.\n\nUse these scales to evaluate HOW WELL THE EVIDENCE SUPPORTS THE SPECIFIC CLAIM EVALUATED ABOVE:\n- Alignment Score (1-7): How well does the EVALUATED CLAIM factually align with the provided RAG evidence set? [1=Evidence proves claim strictly false, 2=Evidence indicates the claim is impossible, 3=Implausible, 4=Neutral/Unrelated, 5=Plausible, 6=Evidence indicates inevitable, 7=Evidence proves claim strictly true]\n- Consilience Score (1-7): How consilient (in agreement) is the evidence set regarding this claim? [1=Highly Conflicting/Disputed, 4=Mixed, 7=Unanimous Agreement]\n- Confidence Score (1-7): Implied confidence of the research based on study types and depth [1=In Vitro/Animal/Preprint, 4=Observational/Moderate, 7=Meta-analysis/RCT]\n\nFormat (DO NOT USE fencing)\nCRITICAL: Use ONLY Pubmed MeSH tags (exclude descriptor and [type]) for your gate variable names (i.e.,.the \"gates\") so they will be standardized globally.

This review examines modifiable non-infectious determinants across the life course and proposes integrated prevention strategies. Key factors include vitamin D deficiency, low UV exposure, smoking, adolescent obesity, air pollution, and chemical environmental exposures. Mendelian randomization studies support the causality of several determinants, particularly low vitamin D and high BMI. Adolescence emerges as a critical susceptibility window where the maturing immune system is uniquely sensitive to metabolic and environmental triggers. Among validated interventions, vitamin D supplementation stands out for its ability to reduce disease activity in early MS. Effective prevention requires both individual actions and structural public health policies, such as air quality regulations and urban \"walkability\". Future efforts should prioritize multimodal strategies targeting high-risk youths through the educational system (physical activity, weight management, and smoking prevention). These holistic approaches offer broad-spectrum benefits, reducing the burden of MS while preventing comorbidities, including cardiovascular, metabolic but also cancer."

The aim of this study was to investigate the association between occupational exposure to industrial dust and MS and to assess potential interactions with smoking and HLA-DRB1*15:01. We conducted a Swedish population-based case-control study. Patients with incident MS age 16-70 years were consecutively identified by neurologists at 40 clinics (2005-2015). Eligibility criteria for participants were age 16-70 years, residence in Sweden, and a neurologist-confirmed diagnosis of MS according to the McDonald criteria. Controls without MS were randomly sampled from the national population register using density sampling and frequency-matched to cases on age, sex, and residential area. Occupational dust exposure was assessed using questionnaire data. Logistic regression was used to estimate odds ratios (ORs) and 95% CIs. Additive interactions between dust exposure and smoking and between dust exposure and HLA-DRB1*15:01 were assessed by calculating the attributable proportion (AP) due to interaction. An AP >0 is considered evidence of interaction. The analytic sample included 2,070 participants and 2,899 controls. The mean age at index was 34.4 years for participants and 35.4 years for controls. Women comprised 72.5% of participants and 75.1% of controls. Industrial dust exposure was associated with increased rate of MS (OR 1.30, 95% CI 1.05-1.63), with a dose-response relationship with duration (OR per 1-year exposure 1.03, 95% CI 1.00-1.06). Evidence of additive interactions was observed between dust exposure and smoking (AP 0.32, 95% CI 0.03-0.62) and between dust exposure and HLA-DRB1*15:01 (AP 0.25, 95% CI 0.002-0.52). Participants who smoked, were exposed to dust, and carried the HLA-DRB1*15:01 allele had an 11-fold increased rate of MS (OR 11.1, 95% CI 5.7-21.9), compared with those without any of these risk factors. Occupational dust exposure was associated with increased rate of MS, particularly in combination with smoking and HLA-DRB1*15:01, suggesting joint effects of occupational, environmental, and genetic risk factors. The reliance on self-reported occupational histories and potential residual confounding are important limitations. Further studies are warranted to clarify underlying mechanisms and to inform preventive strategies."

Nicotine-derived nitrosamine ketone (NNK), a potent tobacco-specific nitrosamine, has been implicated in MS; however, its mechanistic contribution to disease pathogenesis remains poorly understood. Here, we applied an integrative multi-level approach to investigate the potential role of NNK in MS. Mendelian randomization (MR) analysis identified genetically predicted dipeptidyl peptidase-4 (DPP4) activity as being associated with MS susceptibility. Molecular docking further demonstrated feasible interactions between NNK and candidate proteins, including DPP4, providing theoretical plausibility for chemical-protein interactions. In experimental autoimmune encephalomyelitis (EAE) mice, systemic NNK exposure accelerated disease onset, aggravated neurological deficits, and enhanced immune cell infiltration and demyelination within the central nervous system (CNS), accompanied by increased DPP4 expression in inflamed regions. Consistent with these observations, in vitro NNK treatment impaired endothelial barrier integrity in bEnd.3 cells by reducing tight junction proteins (ZO-1, Claudin-5, and Occludin) and upregulating adhesion molecules (VCAM-1 and ICAM-1). NNK exposure also triggered inflammatory activation in BV2 microglia, resulting in elevated expression of TNF-\u03b1, IL-1\u03b2, and IL-6. Importantly, DPP4 silencing partially restored endothelial junctional integrity and attenuated pro-adhesive signaling in endothelial cells while reducing inflammatory cytokine expression in microglia, suggesting that DPP4 is functionally involved in NNK-induced neurovascular inflammation. Together, these findings suggest that NNK exposure may modulate neuroinflammatory processes relevant to MS through blood-brain barrier (BBB) disruption and microglial activation, with DPP4 potentially being involved in this process. This study provides mechanistic insights into how smoking-associated toxins may influence MS progression and highlights DPP4-related pathways as potential targets for therapeutic investigation."

Nicotine-derived nitrosamine ketone (NNK), a potent tobacco-specific nitrosamine, has been implicated in MS; however, its mechanistic contribution to disease pathogenesis remains poorly understood. Here, we applied an integrative multi-level approach to investigate the potential role of NNK in MS. Mendelian randomization (MR) analysis identified genetically predicted dipeptidyl peptidase-4 (DPP4) activity as being associated with MS susceptibility. Molecular docking further demonstrated feasible interactions between NNK and candidate proteins, including DPP4, providing theoretical plausibility for chemical-protein interactions. In experimental autoimmune encephalomyelitis (EAE) mice, systemic NNK exposure accelerated disease onset, aggravated neurological deficits, and enhanced immune cell infiltration and demyelination within the central nervous system (CNS), accompanied by increased DPP4 expression in inflamed regions. Consistent with these observations, in vitro NNK treatment impaired endothelial barrier integrity in bEnd.3 cells by reducing tight junction proteins (ZO-1, Claudin-5, and Occludin) and upregulating adhesion molecules (VCAM-1 and ICAM-1). NNK exposure also triggered inflammatory activation in BV2 microglia, resulting in elevated expression of TNF-\u03b1, IL-1\u03b2, and IL-6. Importantly, DPP4 silencing partially restored endothelial junctional integrity and attenuated pro-adhesive signaling in endothelial cells while reducing inflammatory cytokine expression in microglia, suggesting that DPP4 is functionally involved in NNK-induced neurovascular inflammation. Together, these findings suggest that NNK exposure may modulate neuroinflammatory processes relevant to MS through blood-brain barrier (BBB) disruption and microglial activation, with DPP4 potentially being involved in this process. This study provides mechanistic insights into how smoking-associated toxins may influence MS progression and highlights DPP4-related pathways as potential targets for therapeutic investigation."

Environmental risk factors, such as vitamin D deficiency and obesity, have also been implicated in multiple sclerosis pathogenesis. Statistical approaches building on these genetic data, such as Mendelian randomization and co-localization, have established putative causal links between environmental risk factors and multiple sclerosis risk, most notably for vitamin D and body mass index. However, studies have thus far revealed limited statistically significant interactions between host genetics and environmental factors beyond the major histocompatibility complex. Epigenetics (the study of non-nucleotide alterations to DNA, such as DNA methylation or histone acetylation) might provide a mechanistic framework for understanding how environmental and genetic factors interact in multiple sclerosis. Environmental factors, such as Epstein-Barr virus infection, vitamin D deficiency and smoking, are associated with epigenetic modifications at key multiple sclerosis-related genomic loci, altering the expression of multiple sclerosis risk genes in a cell type-specific manner. Transcriptomics have identified significant pathways via which genetic risk is realized, potentially providing targets for intervention. This review synthesizes current evidence on gene-environment interactions in the context of multiple sclerosis genome-wide association study findings, evaluates the strengths and limitations of various study methodologies, and discusses the challenges in elucidating the interplay between genetics and environmental factors. We propose potential strategies for future research to advance our understanding of the biological mechanisms underlying multiple sclerosis susceptibility in at-risk individuals."

To our knowledge, n-hexane-toxic neuropathy presenting with a cauda equina-like syndrome has not previously been reported. CASE PRESENTATION: A 55-year-old man developed sensory and motor polyneuropathy over a 3-month period, with nerve conduction studies indicating demyelination. Initial treatment for suspected chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) with steroids and plasma exchange was ineffective, leading to worsening symptoms. The patient and his colleagues were found to have been habitually exposed to n-hexane in their printing work, and a sural nerve biopsy revealed the pathological findings typical of n-hexane-toxic neuropathy. Notably, cauda equina inflammation was observed on MRI and in the cerebrospinal fluid. Following intravenous immunoglobulin therapy, both neurological symptoms and findings from nerve conduction studies, MRI, and cerebrospinal fluid analysis gradually improved, eventually leading the absence of impairment in activities of daily living. CONCLUSION: In cases of polyneuropathy accompanied by inflammation of the cauda equina, and if exposure to n-hexane cannot be ruled out, sural nerve biopsy could be considered to assess for n-hexane-toxic neuropathy."

The comparison tested how solvent polarity and hydrogen-bonding behavior affect product distribution under otherwise fixed conditions. FTIR, GPC, and GC-MS showed differences among the five soluble fractions. Protic solvents retained more phenolic monomers and oligomers, whereas aprotic solvents gave more oxidized products and different H:G:S profiles. The ethanol fraction had the highest apparent thermal stability (Ea\u00a0=\u00a04.14\u00a0kJ/mol; DTG peak\u00a0=\u00a0380\u00a0\u00b0C) and the lowest Mw (856\u00a0Da). Methyl cellosolve produced the highest-Mw fraction (2985\u00a0Da) and a more balanced H:G:S distribution. Guaiacol accounted for 40.6% of the ethanol fraction, coumaran for 70.4% of the THF fraction, and syringol for 17.2% of the methyl cellosolve fraction. THF-only controls did not produce a peak assigned to coumaran in the relevant retention-time window, which supports a lignin-derived origin for this signal under the tested conditions. The screening results link solvent properties to lignin fragmentation and the composition of the soluble products. Solvent recycling, residue characterization, process optimization, and atom-resolved mechanistic studies remain to be completed."

Network toxicology identified 252 shared targets between sleep-related environmental pollutants (SREPs: NO2, formaldehyde, benzene) and SD. PPI network and diagnostic model identified four hub genes (HSP90AA1, RELA, PTGS2, MMP9) with moderate-to-high predictive value (AUC: 0.708-0.979). Immune infiltration analysis showing elevated T cells and reduced astrocytes and neurons in patients with SD. Molecular simulations confirmed stable SREP-hub protein binding, with benzene exhibiting the highest affinity.

In vivo, SREPs metabolites disrupted sleep architecture, impaired the blood-brain barrier (BBB), and induced neurobehavioral deficits. In vitro studies using brain endothelial cells (BMVECs) revealed that SREPs directly increase permeability, suppress tight junctions, and activate a pro-inflammatory cascade involving NF-\u03baB signaling, enhanced MMP9 activity, and prostaglandin E2 synthesis. Curcumin intervention effectively counteracted these effects, restoring BBB integrity, normalizing sleep patterns, and suppressing hub gene expression and neuroinflammation in vivo and in vitro by targeting the identified hub gene network.

T.G. Hartley (syn. Evodia rutaecarpa (Juss.) Benth., Rutaceae), known as Wuzhuyu in Chinese and Evodiae Fructus (EF) in English, is a traditional Chinese medicine (TCM) with a history of over two thousand years. It was first documented in Shen Nong's Herbal Classic for its efficacy in dispersing cold, relieving pain, and alleviating nausea, vomiting, and diarrhea, leading to its historical use in managing gastrointestinal ailments. However, the clinical application of EF has been limited due to its associated hepatotoxicity. Existing studies have confirmed that evodiamine, rutaecarpine and other alkaloids induce hepatotoxicity via multi-pathways, but the core toxic fraction, multi-component synergistic effects and systematic toxic network of EF remain unclear. This study aims to identify the key hepatotoxic fraction of Evodiae Fructus (EF) and elucidate its underlying mechanisms. A high-throughput zebrafish model was used to screen EF extracts with different polar solvents. The hepatotoxicity of the target fraction was validated in mice. UPLC-Q-TOF-MS/MS, integrated network pharmacology, proteomic and transcriptomic analyses were performed in zebrafish and mice to screen toxic pathways, with western blot and qRT-PCR validation. High-throughput zebrafish screening of five polar extracts of EF identified the dichloromethane extract (DEEF) as the core hepatotoxic fraction. Both zebrafish and mouse models consistently indicated that DEEF induced a dose-dependent elevation of serum ALT, AST, and TBA levels, disrupted the architecture of hepatic tissue, and was accompanied by marked hepatocyte apoptosis. In mice, Masson's trichrome staining further revealed abnormal collagen deposition, along with extensive infiltration of inflammatory cells. UPLC-Q-TOF-MS/MS analysis identified 73 compounds in DEEF, with 48 alkaloids (indole and quinolone types) being the dominant components, in addition to flavonoids, limonoids, and organic acids. Integrated network pharmacology, transcriptomic and proteomic analyses revealed dose-dependent global alterations in hepatic gene and protein expression profiles. Mechanistically, DEEF upregulated bile acids (BAs) synthesis enzymes (CYP7A1, CYP27A1) and downregulated efflux transporters (BSEP, MRP2). These changes were associated with activation of PI3K-AKT/MAPK/p53/NF-\u03baB pathways and modulation of the Bax/Bcl-2/Caspase-3 apoptotic axis, as indicated by multi-omics enrichment and validated by protein and gene expression analyses. This study is the first to confirm that DEEF represents the core toxic fraction of EF and to disclose that its hepatotoxic mechanism is driven by the crosstalk between BAs metabolism disorder and multi-signaling cascade. Our findings fill the research gap between studies on crude extract and monomers, and provide a critical foundation for targeted detoxification and safe clinical application of EF."

T.G. Hartley (syn. Evodia rutaecarpa (Juss.) Benth., Rutaceae), known as Wuzhuyu in Chinese and Evodiae Fructus (EF) in English, is a traditional Chinese medicine (TCM) with a history of over two thousand years. It was first documented in Shen Nong's Herbal Classic for its efficacy in dispersing cold, relieving pain, and alleviating nausea, vomiting, and diarrhea, leading to its historical use in managing gastrointestinal ailments. However, the clinical application of EF has been limited due to its associated hepatotoxicity. Existing studies have confirmed that evodiamine, rutaecarpine and other alkaloids induce hepatotoxicity via multi-pathways, but the core toxic fraction, multi-component synergistic effects and systematic toxic network of EF remain unclear. This study aims to identify the key hepatotoxic fraction of Evodiae Fructus (EF) and elucidate its underlying mechanisms. A high-throughput zebrafish model was used to screen EF extracts with different polar solvents. The hepatotoxicity of the target fraction was validated in mice. UPLC-Q-TOF-MS/MS, integrated network pharmacology, proteomic and transcriptomic analyses were performed in zebrafish and mice to screen toxic pathways, with western blot and qRT-PCR validation. High-throughput zebrafish screening of five polar extracts of EF identified the dichloromethane extract (DEEF) as the core hepatotoxic fraction. Both zebrafish and mouse models consistently indicated that DEEF induced a dose-dependent elevation of serum ALT, AST, and TBA levels, disrupted the architecture of hepatic tissue, and was accompanied by marked hepatocyte apoptosis. In mice, Masson's trichrome staining further revealed abnormal collagen deposition, along with extensive infiltration of inflammatory cells. UPLC-Q-TOF-MS/MS analysis identified 73 compounds in DEEF, with 48 alkaloids (indole and quinolone types) being the dominant components, in addition to flavonoids, limonoids, and organic acids. Integrated network pharmacology, transcriptomic and proteomic analyses revealed dose-dependent global alterations in hepatic gene and protein expression profiles. Mechanistically, DEEF upregulated bile acids (BAs) synthesis enzymes (CYP7A1, CYP27A1) and downregulated efflux transporters (BSEP, MRP2). These changes were associated with activation of PI3K-AKT/MAPK/p53/NF-\u03baB pathways and modulation of the Bax/Bcl-2/Caspase-3 apoptotic axis, as indicated by multi-omics enrichment and validated by protein and gene expression analyses. This study is the first to confirm that DEEF represents the core toxic fraction of EF and to disclose that its hepatotoxic mechanism is driven by the crosstalk between BAs metabolism disorder and multi-signaling cascade. Our findings fill the research gap between studies on crude extract and monomers, and provide a critical foundation for targeted detoxification and safe clinical application of EF."

Cumulative lifetime exposures (i.e. the exposome) contribute to ILD onset and progression by interacting with genetic susceptibility and influencing multiple molecular pathways. This review summarizes current evidence evaluating how environmental exposures interact across the genome, epigenome, transcriptome, proteome, metabolome, and microbiome to drive ILD pathogenesis. Environmental exposures, including air pollution, influence ILD risk through interactions with genetic factors that modify disease susceptibility. Epigenetic mechanisms, particularly DNA methylation, reflect key pathways through which exposures may contribute to ILD onset and progression and serve as sensitive biomarkers of environmental injury. Exposure-associated molecular alterations can be detected across multiple omic layers, including transcriptomic, proteomic, and metabolomic profiles. In parallel, exposures like cigarette smoking, silica, and air pollution influence the respiratory microbiome, with potential downstream effects on immune responses and fibrogenesis. Integrating these findings highlights environmentally-sensitive pathways that may represent novel targets for therapeutic modulation. Integration of exposomic and multiomic molecular frameworks offers new opportunities to improve ILD risk stratification, prognostication, and precision therapeutic development, while also strengthening our mechanistic understanding of environmentally-mediated disease."

This review examines modifiable non-infectious determinants across the life course and proposes integrated prevention strategies. Key factors include vitamin D deficiency, low UV exposure, smoking, adolescent obesity, air pollution, and chemical environmental exposures. Mendelian randomization studies support the causality of several determinants, particularly low vitamin D and high BMI. Adolescence emerges as a critical susceptibility window where the maturing immune system is uniquely sensitive to metabolic and environmental triggers. Among validated interventions, vitamin D supplementation stands out for its ability to reduce disease activity in early MS. Effective prevention requires both individual actions and structural public health policies, such as air quality regulations and urban \"walkability\". Future efforts should prioritize multimodal strategies targeting high-risk youths through the educational system (physical activity, weight management, and smoking prevention). These holistic approaches offer broad-spectrum benefits, reducing the burden of MS while preventing comorbidities, including cardiovascular, metabolic but also cancer."

Nicotine-derived nitrosamine ketone (NNK), a potent tobacco-specific nitrosamine, has been implicated in MS; however, its mechanistic contribution to disease pathogenesis remains poorly understood. Here, we applied an integrative multi-level approach to investigate the potential role of NNK in MS. Mendelian randomization (MR) analysis identified genetically predicted dipeptidyl peptidase-4 (DPP4) activity as being associated with MS susceptibility. Molecular docking further demonstrated feasible interactions between NNK and candidate proteins, including DPP4, providing theoretical plausibility for chemical-protein interactions. In experimental autoimmune encephalomyelitis (EAE) mice, systemic NNK exposure accelerated disease onset, aggravated neurological deficits, and enhanced immune cell infiltration and demyelination within the central nervous system (CNS), accompanied by increased DPP4 expression in inflamed regions. Consistent with these observations, in vitro NNK treatment impaired endothelial barrier integrity in bEnd.3 cells by reducing tight junction proteins (ZO-1, Claudin-5, and Occludin) and upregulating adhesion molecules (VCAM-1 and ICAM-1). NNK exposure also triggered inflammatory activation in BV2 microglia, resulting in elevated expression of TNF-\u03b1, IL-1\u03b2, and IL-6. Importantly, DPP4 silencing partially restored endothelial junctional integrity and attenuated pro-adhesive signaling in endothelial cells while reducing inflammatory cytokine expression in microglia, suggesting that DPP4 is functionally involved in NNK-induced neurovascular inflammation. Together, these findings suggest that NNK exposure may modulate neuroinflammatory processes relevant to MS through blood-brain barrier (BBB) disruption and microglial activation, with DPP4 potentially being involved in this process. This study provides mechanistic insights into how smoking-associated toxins may influence MS progression and highlights DPP4-related pathways as potential targets for therapeutic investigation."

To our knowledge, n-hexane-toxic neuropathy presenting with a cauda equina-like syndrome has not previously been reported. CASE PRESENTATION: A 55-year-old man developed sensory and motor polyneuropathy over a 3-month period, with nerve conduction studies indicating demyelination. Initial treatment for suspected chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) with steroids and plasma exchange was ineffective, leading to worsening symptoms. The patient and his colleagues were found to have been habitually exposed to n-hexane in their printing work, and a sural nerve biopsy revealed the pathological findings typical of n-hexane-toxic neuropathy. Notably, cauda equina inflammation was observed on MRI and in the cerebrospinal fluid. Following intravenous immunoglobulin therapy, both neurological symptoms and findings from nerve conduction studies, MRI, and cerebrospinal fluid analysis gradually improved, eventually leading the absence of impairment in activities of daily living. CONCLUSION: In cases of polyneuropathy accompanied by inflammation of the cauda equina, and if exposure to n-hexane cannot be ruled out, sural nerve biopsy could be considered to assess for n-hexane-toxic neuropathy."

The ethanol fraction had the highest apparent thermal stability (Ea\u00a0=\u00a04.14\u00a0kJ/mol; DTG peak\u00a0=\u00a0380\u00a0\u00b0C) and the lowest Mw (856\u00a0Da). Methyl cellosolve produced the highest-Mw fraction (2985\u00a0Da) and a more balanced H:G:S distribution. Guaiacol accounted for 40.6% of the ethanol fraction, coumaran for 70.4% of the THF fraction, and syringol for 17.2% of the methyl cellosolve fraction. THF-only controls did not produce a peak assigned to coumaran in the relevant retention-time window, which supports a lignin-derived origin for this signal under the tested conditions. The screening results link solvent properties to lignin fragmentation and the composition of the soluble products. Solvent recycling, residue characterization, process optimization, and atom-resolved mechanistic studies remain to be completed."

Network toxicology identified 252 shared targets between sleep-related environmental pollutants (SREPs: NO2, formaldehyde, benzene) and SD. PPI network and diagnostic model identified four hub genes (HSP90AA1, RELA, PTGS2, MMP9) with moderate-to-high predictive value (AUC: 0.708-0.979). Immune infiltration analysis showing elevated T cells and reduced astrocytes and neurons in patients with SD. Molecular simulations confirmed stable SREP-hub protein binding, with benzene exhibiting the highest affinity. Crucially, mixed SREPs exposure induced more severe toxicity than individual pollutants, demonstrating true synergistic disruption. In vivo, SREPs metabolites disrupted sleep architecture, impaired the blood-brain barrier (BBB), and induced neurobehavioral deficits. In vitro studies using brain endothelial cells (BMVECs) revealed that SREPs directly increase permeability, suppress tight junctions, and activate a pro-inflammatory cascade involving NF-\u03baB signaling, enhanced MMP9 activity, and prostaglandin E2 synthesis. Curcumin intervention effectively counteracted these effects, restoring BBB integrity, normalizing sleep patterns, and suppressing hub gene expression and neuroinflammation in vivo and in vitro by targeting the identified hub gene network. Our integrated computational-experimental strategy establishes a novel \"pollutant-BBB-neuroimmune-sleep\" axis, providing a mechanistic framework for assessing cumulative environmental risks and advancing targeted interventions."

Cumulative lifetime exposures (i.e. the exposome) contribute to ILD onset and progression by interacting with genetic susceptibility and influencing multiple molecular pathways. This review summarizes current evidence evaluating how environmental exposures interact across the genome, epigenome, transcriptome, proteome, metabolome, and microbiome to drive ILD pathogenesis. Environmental exposures, including air pollution, influence ILD risk through interactions with genetic factors that modify disease susceptibility. Epigenetic mechanisms, particularly DNA methylation, reflect key pathways through which exposures may contribute to ILD onset and progression and serve as sensitive biomarkers of environmental injury. Exposure-associated molecular alterations can be detected across multiple omic layers, including transcriptomic, proteomic, and metabolomic profiles. In parallel, exposures like cigarette smoking, silica, and air pollution influence the respiratory microbiome, with potential downstream effects on immune responses and fibrogenesis. Integrating these findings highlights environmentally-sensitive pathways that may represent novel targets for therapeutic modulation. Integration of exposomic and multiomic molecular frameworks offers new opportunities to improve ILD risk stratification, prognostication, and precision therapeutic development, while also strengthening our mechanistic understanding of environmentally-mediated disease."

Although pesticides, industrial solvents, heavy metals, and air pollutants have long been implicated as potentially modifiable PD risk factors, climate change is now reshaping and amplifying these hazards through rising temperatures, worsening air quality, increased pesticide demand, extreme weather events, and wildfire-related particulate matter.This narrative review moves beyond a conventional exposure-based summary by integrating environmental toxicology, climate science, epidemiology, and mechanistic neuroscience to reframe PD risk within the context of planetary health. We summarize evidence linking major environmental hazards to PD pathogenesis, emphasizing convergent mechanisms such as oxidative stress, mitochondrial dysfunction, impaired proteostasis, neuroinflammation, blood-brain barrier disruption, and \u03b1-synuclein aggregation. We further discuss how climate-related changes may intensify these pathways and disproportionately affect vulnerable populations, including agricultural workers, older adults, socioeconomically disadvantaged communities, and individuals living in rapidly industrializing or climate-sensitive regions. Importantly, we highlight clinical and public health implications by proposing that structured environmental and occupational exposure assessment should be incorporated into PD risk evaluation, early recognition, preventive counseling, and research design. We also discuss exposure reduction, workplace protection, environmental monitoring, and regulatory policy as prevention-oriented strategies. By positioning environmental hazards and climate change as interconnected, underrecognized, and potentially modifiable contributors to PD, this review provides a framework for clinicians, researchers, and policymakers seeking to reduce the future global burden of neurodegenerative disease. Parkinson's disease (PD) is a common neurodegenerative disorder that develops over time and affects movement, balance, and many daily activities. While genes play a role, most cases of PD do not arise solely from genetics. Growing evidence shows that environmental exposures, such as pesticides, industrial chemicals, heavy metals, and air pollution, can increase the risk of developing PD. Importantly, many of these exposures can be reduced or prevented. Climate change is worsening these environmental risks. Higher temperatures, poorer air quality, increased pesticide use, and more frequent wildfires are increasing human exposure to harmful pollutants worldwide. Together, these changes may increase the number of people affected by PD, especially in communities already facing environmental or social disadvantages. This review explains how environmental toxins can damage brain cells through shared biological processes, including oxidative stress, inflammation, and abnormal protein buildup. It also highlights regions and populations that may be more vulnerable to these risks. From a healthcare perspective, understanding a person's environmental and work-related exposures can help identify those at higher risk, support earlier recognition of PD, and guide prevention advice. Overall, environmental toxins and climate change are underrecognized yet actionable determinants of PD. Increasing awareness, improving environmental protections, and integrating exposure history into clinical care are key steps toward reducing the future global burden of PD."

Glycol ethers consist in a widely used class of organic solvents leading to workers and consumers exposure via many applications. Ethylene glycol ethers are gradually being replaced by propylene glycol ethers thought to be less toxic. However, their neurotoxicity is not systematically assessed before placing them on the market. Therefore, this study investigated the potential neurotoxicity of propylene glycol butyl ether (PGBE) for which no official occupational limit has been established. To this aim, new approach methodologies have been used. Human induced pluripotent stem cells-derived BrainSpheres model was exposed to PGBE and to its assumed human main metabolite, 2-butoxypropanoic acid (2BPA). An integrative multiomic approach (transcriptomics, proteomics, metabolomics and lipidomics) was adopted to assess molecular alterations, derive benchmark concentrations and define potential mechanisms of action. PGBE was neurotoxic at occupationally relevant exposure concentrations. This was shown for the first time in human cells. Although PGBE was more cytotoxic than 2BPA, both compounds showed very similar neurotoxicity. PGBE and 2BPA strongly affected the cell cycle, induced oxidative stress and perturbed energy and lipid metabolism. They also targeted specific nervous system processes, such as axon guidance and synapse organization. Finally, 2BPA might trigger ferroptosis by increased iron uptake. Our in vitro results show an urgent need for public health authorities to carefully assess the risk glycol ethers pose to humans, to properly protect the workers as well as individuals in the general population unknowingly exposed from indoor air contaminations."

Key factors include vitamin D deficiency, low UV exposure, smoking, adolescent obesity, air pollution, and chemical environmental exposures. Mendelian randomization studies support the causality of several determinants, particularly low vitamin D and high BMI. Adolescence emerges as a critical susceptibility window where the maturing immune system is uniquely sensitive to metabolic and environmental triggers. Among validated interventions, vitamin D supplementation stands out for its ability to reduce disease activity in early MS. Effective prevention requires both individual actions and structural public health policies, such as air quality regulations and urban \"walkability\". Future efforts should prioritize multimodal strategies targeting high-risk youths through the educational system (physical activity, weight management, and smoking prevention). These holistic approaches offer broad-spectrum benefits, reducing the burden of MS while preventing comorbidities, including cardiovascular, metabolic but also cancer."

Nicotine-derived nitrosamine ketone (NNK), a potent tobacco-specific nitrosamine, has been implicated in MS; however, its mechanistic contribution to disease pathogenesis remains poorly understood. Here, we applied an integrative multi-level approach to investigate the potential role of NNK in MS. Mendelian randomization (MR) analysis identified genetically predicted dipeptidyl peptidase-4 (DPP4) activity as being associated with MS susceptibility. Molecular docking further demonstrated feasible interactions between NNK and candidate proteins, including DPP4, providing theoretical plausibility for chemical-protein interactions. In experimental autoimmune encephalomyelitis (EAE) mice, systemic NNK exposure accelerated disease onset, aggravated neurological deficits, and enhanced immune cell infiltration and demyelination within the central nervous system (CNS), accompanied by increased DPP4 expression in inflamed regions. Consistent with these observations, in vitro NNK treatment impaired endothelial barrier integrity in bEnd.3 cells by reducing tight junction proteins (ZO-1, Claudin-5, and Occludin) and upregulating adhesion molecules (VCAM-1 and ICAM-1). NNK exposure also triggered inflammatory activation in BV2 microglia, resulting in elevated expression of TNF-\u03b1, IL-1\u03b2, and IL-6. Importantly, DPP4 silencing partially restored endothelial junctional integrity and attenuated pro-adhesive signaling in endothelial cells while reducing inflammatory cytokine expression in microglia, suggesting that DPP4 is functionally involved in NNK-induced neurovascular inflammation. Together, these findings suggest that NNK exposure may modulate neuroinflammatory processes relevant to MS through blood-brain barrier (BBB) disruption and microglial activation, with DPP4 potentially being involved in this process. This study provides mechanistic insights into how smoking-associated toxins may influence MS progression and highlights DPP4-related pathways as potential targets for therapeutic investigation."

Emerging therapies now incorporate personalized nutrition, lifestyle changes, and environmental risk mitigation alongside traditional drugs, supported by advances in multi-omics, digital health, and systems biology. Public health efforts to reduce neurotoxic exposure and encourage healthy habits further strengthen these approaches. This review summarizes existing mechanistic and clinical knowledge, with a focus on the potential of nutritional, environmental, and lifestyle interventions in neurological diseases. It also outlines the future research required to enhance precision neurology and strategies for brain health prevention."

To our knowledge, n-hexane-toxic neuropathy presenting with a cauda equina-like syndrome has not previously been reported. CASE PRESENTATION: A 55-year-old man developed sensory and motor polyneuropathy over a 3-month period, with nerve conduction studies indicating demyelination. Initial treatment for suspected chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) with steroids and plasma exchange was ineffective, leading to worsening symptoms. The patient and his colleagues were found to have been habitually exposed to n-hexane in their printing work, and a sural nerve biopsy revealed the pathological findings typical of n-hexane-toxic neuropathy. Notably, cauda equina inflammation was observed on MRI and in the cerebrospinal fluid. Following intravenous immunoglobulin therapy, both neurological symptoms and findings from nerve conduction studies, MRI, and cerebrospinal fluid analysis gradually improved, eventually leading the absence of impairment in activities of daily living. CONCLUSION: In cases of polyneuropathy accompanied by inflammation of the cauda equina, and if exposure to n-hexane cannot be ruled out, sural nerve biopsy could be considered to assess for n-hexane-toxic neuropathy."

In this study, technical alkali lignin from soda bagasse was ozonated in ethanol, tetrahydrofuran (THF), 1,4-dioxane, acetone, or methyl cellosolve to combine oxidative depolymerization with solvent fractionation. The comparison tested how solvent polarity and hydrogen-bonding behavior affect product distribution under otherwise fixed conditions. FTIR, GPC, and GC-MS showed differences among the five soluble fractions. Protic solvents retained more phenolic monomers and oligomers, whereas aprotic solvents gave more oxidized products and different H:G:S profiles. The ethanol fraction had the highest apparent thermal stability (Ea\u00a0=\u00a04.14\u00a0kJ/mol; DTG peak\u00a0=\u00a0380\u00a0\u00b0C) and the lowest Mw (856\u00a0Da). Methyl cellosolve produced the highest-Mw fraction (2985\u00a0Da) and a more balanced H:G:S distribution. Guaiacol accounted for 40.6% of the ethanol fraction, coumaran for 70.4% of the THF fraction, and syringol for 17.2% of the methyl cellosolve fraction. THF-only controls did not produce a peak assigned to coumaran in the relevant retention-time window, which supports a lignin-derived origin for this signal under the tested conditions. The screening results link solvent properties to lignin fragmentation and the composition of the soluble products. Solvent recycling, residue characterization, process optimization, and atom-resolved mechanistic studies remain to be completed."

Network toxicology identified 252 shared targets between sleep-related environmental pollutants (SREPs: NO2, formaldehyde, benzene) and SD. PPI network and diagnostic model identified four hub genes (HSP90AA1, RELA, PTGS2, MMP9) with moderate-to-high predictive value (AUC: 0.708-0.979). Immune infiltration analysis showing elevated T cells and reduced astrocytes and neurons in patients with SD. Molecular simulations confirmed stable SREP-hub protein binding, with benzene exhibiting the highest affinity. Crucially, mixed SREPs exposure induced more severe toxicity than individual pollutants, demonstrating true synergistic disruption. In vivo, SREPs metabolites disrupted sleep architecture, impaired the blood-brain barrier (BBB), and induced neurobehavioral deficits. In vitro studies using brain endothelial cells (BMVECs) revealed that SREPs directly increase permeability, suppress tight junctions, and activate a pro-inflammatory cascade involving NF-\u03baB signaling, enhanced MMP9 activity, and prostaglandin E2 synthesis. Curcumin intervention effectively counteracted these effects, restoring BBB integrity, normalizing sleep patterns, and suppressing hub gene expression and neuroinflammation in vivo and in vitro by targeting the identified hub gene network. Our integrated computational-experimental strategy establishes a novel \"pollutant-BBB-neuroimmune-sleep\" axis, providing a mechanistic framework for assessing cumulative environmental risks and advancing targeted interventions."

It was first documented in Shen Nong's Herbal Classic for its efficacy in dispersing cold, relieving pain, and alleviating nausea, vomiting, and diarrhea, leading to its historical use in managing gastrointestinal ailments. However, the clinical application of EF has been limited due to its associated hepatotoxicity. Existing studies have confirmed that evodiamine, rutaecarpine and other alkaloids induce hepatotoxicity via multi-pathways, but the core toxic fraction, multi-component synergistic effects and systematic toxic network of EF remain unclear. This study aims to identify the key hepatotoxic fraction of Evodiae Fructus (EF) and elucidate its underlying mechanisms. A high-throughput zebrafish model was used to screen EF extracts with different polar solvents. The hepatotoxicity of the target fraction was validated in mice. UPLC-Q-TOF-MS/MS, integrated network pharmacology, proteomic and transcriptomic analyses were performed in zebrafish and mice to screen toxic pathways, with western blot and qRT-PCR validation. High-throughput zebrafish screening of five polar extracts of EF identified the dichloromethane extract (DEEF) as the core hepatotoxic fraction. Both zebrafish and mouse models consistently indicated that DEEF induced a dose-dependent elevation of serum ALT, AST, and TBA levels, disrupted the architecture of hepatic tissue, and was accompanied by marked hepatocyte apoptosis. In mice, Masson's trichrome staining further revealed abnormal collagen deposition, along with extensive infiltration of inflammatory cells. UPLC-Q-TOF-MS/MS analysis identified 73 compounds in DEEF, with 48 alkaloids (indole and quinolone types) being the dominant components, in addition to flavonoids, limonoids, and organic acids. Integrated network pharmacology, transcriptomic and proteomic analyses revealed dose-dependent global alterations in hepatic gene and protein expression profiles. Mechanistically, DEEF upregulated bile acids (BAs) synthesis enzymes (CYP7A1, CYP27A1) and downregulated efflux transporters (BSEP, MRP2). These changes were associated with activation of PI3K-AKT/MAPK/p53/NF-\u03baB pathways and modulation of the Bax/Bcl-2/Caspase-3 apoptotic axis, as indicated by multi-omics enrichment and validated by protein and gene expression analyses. This study is the first to confirm that DEEF represents the core toxic fraction of EF and to disclose that its hepatotoxic mechanism is driven by the crosstalk between BAs metabolism disorder and multi-signaling cascade. Our findings fill the research gap between studies on crude extract and monomers, and provide a critical foundation for targeted detoxification and safe clinical application of EF."

Cumulative lifetime exposures (i.e. the exposome) contribute to ILD onset and progression by interacting with genetic susceptibility and influencing multiple molecular pathways. This review summarizes current evidence evaluating how environmental exposures interact across the genome, epigenome, transcriptome, proteome, metabolome, and microbiome to drive ILD pathogenesis. Environmental exposures, including air pollution, influence ILD risk through interactions with genetic factors that modify disease susceptibility. Epigenetic mechanisms, particularly DNA methylation, reflect key pathways through which exposures may contribute to ILD onset and progression and serve as sensitive biomarkers of environmental injury. Exposure-associated molecular alterations can be detected across multiple omic layers, including transcriptomic, proteomic, and metabolomic profiles. In parallel, exposures like cigarette smoking, silica, and air pollution influence the respiratory microbiome, with potential downstream effects on immune responses and fibrogenesis. Integrating these findings highlights environmentally-sensitive pathways that may represent novel targets for therapeutic modulation. Integration of exposomic and multiomic molecular frameworks offers new opportunities to improve ILD risk stratification, prognostication, and precision therapeutic development, while also strengthening our mechanistic understanding of environmentally-mediated disease."

Although pesticides, industrial solvents, heavy metals, and air pollutants have long been implicated as potentially modifiable PD risk factors, climate change is now reshaping and amplifying these hazards through rising temperatures, worsening air quality, increased pesticide demand, extreme weather events, and wildfire-related particulate matter.This narrative review moves beyond a conventional exposure-based summary by integrating environmental toxicology, climate science, epidemiology, and mechanistic neuroscience to reframe PD risk within the context of planetary health. We summarize evidence linking major environmental hazards to PD pathogenesis, emphasizing convergent mechanisms such as oxidative stress, mitochondrial dysfunction, impaired proteostasis, neuroinflammation, blood-brain barrier disruption, and \u03b1-synuclein aggregation. We further discuss how climate-related changes may intensify these pathways and disproportionately affect vulnerable populations, including agricultural workers, older adults, socioeconomically disadvantaged communities, and individuals living in rapidly industrializing or climate-sensitive regions. Importantly, we highlight clinical and public health implications by proposing that structured environmental and occupational exposure assessment should be incorporated into PD risk evaluation, early recognition, preventive counseling, and research design. We also discuss exposure reduction, workplace protection, environmental monitoring, and regulatory policy as prevention-oriented strategies. By positioning environmental hazards and climate change as interconnected, underrecognized, and potentially modifiable contributors to PD, this review provides a framework for clinicians, researchers, and policymakers seeking to reduce the future global burden of neurodegenerative disease. Parkinson's disease (PD) is a common neurodegenerative disorder that develops over time and affects movement, balance, and many daily activities. While genes play a role, most cases of PD do not arise solely from genetics. Growing evidence shows that environmental exposures, such as pesticides, industrial chemicals, heavy metals, and air pollution, can increase the risk of developing PD. Importantly, many of these exposures can be reduced or prevented. Climate change is worsening these environmental risks. Higher temperatures, poorer air quality, increased pesticide use, and more frequent wildfires are increasing human exposure to harmful pollutants worldwide. Together, these changes may increase the number of people affected by PD, especially in communities already facing environmental or social disadvantages. This review explains how environmental toxins can damage brain cells through shared biological processes, including oxidative stress, inflammation, and abnormal protein buildup. It also highlights regions and populations that may be more vulnerable to these risks. From a healthcare perspective, understanding a person's environmental and work-related exposures can help identify those at higher risk, support earlier recognition of PD, and guide prevention advice. Overall, environmental toxins and climate change are underrecognized yet actionable determinants of PD. Increasing awareness, improving environmental protections, and integrating exposure history into clinical care are key steps toward reducing the future global burden of PD."

While aging and improved diagnostic awareness partly explain this trend, mounting evidence implicates environmental factors as critical contributors. This review synthesizes current literature on exposures such as pesticides, solvents, heavy metals, air pollutants, and infectious agents, emphasizing their mechanistic links to neurodegeneration. These factors interact with genetic susceptibility and aging, supporting the \"multiple-hit\" hypothesis, which posits that PD arises from cumulative insults rather than a single cause. Mitochondrial dysfunction, oxidative stress, neuroinflammation, and impaired protein clearance emerge as convergent pathways underlying dopaminergic vulnerability. Recent findings highlight viral infections-particularly SARS-CoV-2-as potential triggers or amplifiers of PD pathogenesis, raising concerns about long-term neurological sequelae following pandemics. Beyond individual toxins, the exposome concept underscores the lifelong interplay of physical, chemical, and social exposures in shaping disease risk. Climate-related changes, including increased air pollution and wildfire frequency, further compound these risks, suggesting a systemic dimension to PD etiology. Understanding these complex interactions is essential for developing preventive strategies, refining experimental models, and informing public health policies aimed at mitigating environmental contributions to neurodegeneration. This multifactorial perspective offers a foundation for future research targeting modifiable risk factors and resilience mechanisms in PD. Parkinson\u2019s disease (PD) is a brain disorder that affects movement and is becoming more common worldwide. While aging and genetics play a role, research shows that environmental factors\u2014such as pesticides, air pollution, industrial chemicals, and even certain infections\u2014may also increase the risk of developing PD. This article explains how these factors can damage brain cells over time. For example, pesticides and solvents can harm the parts of the brain that control movement. Air pollution and heavy metals may also contribute to brain inflammation and stress. Infections like influenza and COVID-19 could act as \u201ctriggers,\u201d making the brain more vulnerable to damage later in life. Scientists call this the \u201cmultiple-hit\u201d theory, meaning PD often results from a combination of aging, genes, and environmental exposures rather than a single cause. The review also introduces the concept of the \u201cexposome,\u201d which looks at all the things we are exposed to throughout life\u2014chemicals, air quality, diet, and even stress\u2014and how they interact with our biology. Understanding these links can help researchers find ways to prevent PD, improve treatments, and guide public health policies. In short, Parkinson\u2019s disease is not just about getting older or having certain genes. It may also be influenced by what we breathe, eat, and encounter in our environment. By studying these factors, we can work toward reducing risks and protecting brain health."

Glycol ethers consist in a widely used class of organic solvents leading to workers and consumers exposure via many applications. Ethylene glycol ethers are gradually being replaced by propylene glycol ethers thought to be less toxic. However, their neurotoxicity is not systematically assessed before placing them on the market. Therefore, this study investigated the potential neurotoxicity of propylene glycol butyl ether (PGBE) for which no official occupational limit has been established. To this aim, new approach methodologies have been used. Human induced pluripotent stem cells-derived BrainSpheres model was exposed to PGBE and to its assumed human main metabolite, 2-butoxypropanoic acid (2BPA). An integrative multiomic approach (transcriptomics, proteomics, metabolomics and lipidomics) was adopted to assess molecular alterations, derive benchmark concentrations and define potential mechanisms of action. PGBE was neurotoxic at occupationally relevant exposure concentrations. This was shown for the first time in human cells. Although PGBE was more cytotoxic than 2BPA, both compounds showed very similar neurotoxicity. PGBE and 2BPA strongly affected the cell cycle, induced oxidative stress and perturbed energy and lipid metabolism. They also targeted specific nervous system processes, such as axon guidance and synapse organization. Finally, 2BPA might trigger ferroptosis by increased iron uptake. Our in vitro results show an urgent need for public health authorities to carefully assess the risk glycol ethers pose to humans, to properly protect the workers as well as individuals in the general population unknowingly exposed from indoor air contaminations."

Shift work disrupts circadian rhythms and is a potential occupational risk factor for MS, with exposure before age 20 thought to be of additional risk. To investigate associations between retrospective lifetime shift work exposure and MS diagnosis and between prospective shift work exposure and incident MS over 13 years of follow-up in the UK Biobank cohort. Participants that were in work and free of MS at baseline were followed up for 13 years, and lifetime exposure to night, day and mixed shift work was assessed in a subset of participants. Logistic regression and Cox proportional hazard models were applied to test associations between shift work and MS diagnosis, controlling for demographic and lifestyle confounders. Lifetime exposure to mixed, day or night shift work was not associated with an increased risk of MS diagnosis. No significant associations were observed for early-life shift work exposure or in prospective analysis of those reporting shift work at baseline. Factors such as female sex, smoking, childhood obesity and reduced sunlight exposure were consistently associated with higher MS risk. There was no evidence for an association between shift work and the risk of MS diagnosis in this cohort, in retrospective analysis of lifetime exposure or in prospective studies of shift work at baseline following 13 years of follow-up. Further research is needed to elucidate mechanisms and latitudinal variations in shift work-related MS risk."

This review examines modifiable non-infectious determinants across the life course and proposes integrated prevention strategies. Key factors include vitamin D deficiency, low UV exposure, smoking, adolescent obesity, air pollution, and chemical environmental exposures. Mendelian randomization studies support the causality of several determinants, particularly low vitamin D and high BMI. Adolescence emerges as a critical susceptibility window where the maturing immune system is uniquely sensitive to metabolic and environmental triggers. Among validated interventions, vitamin D supplementation stands out for its ability to reduce disease activity in early MS. Effective prevention requires both individual actions and structural public health policies, such as air quality regulations and urban \"walkability\". Future efforts should prioritize multimodal strategies targeting high-risk youths through the educational system (physical activity, weight management, and smoking prevention). These holistic approaches offer broad-spectrum benefits, reducing the burden of MS while preventing comorbidities, including cardiovascular, metabolic but also cancer."

Nicotine-derived nitrosamine ketone (NNK), a potent tobacco-specific nitrosamine, has been implicated in MS; however, its mechanistic contribution to disease pathogenesis remains poorly understood. Here, we applied an integrative multi-level approach to investigate the potential role of NNK in MS. Mendelian randomization (MR) analysis identified genetically predicted dipeptidyl peptidase-4 (DPP4) activity as being associated with MS susceptibility. Molecular docking further demonstrated feasible interactions between NNK and candidate proteins, including DPP4, providing theoretical plausibility for chemical-protein interactions. In experimental autoimmune encephalomyelitis (EAE) mice, systemic NNK exposure accelerated disease onset, aggravated neurological deficits, and enhanced immune cell infiltration and demyelination within the central nervous system (CNS), accompanied by increased DPP4 expression in inflamed regions. Consistent with these observations, in vitro NNK treatment impaired endothelial barrier integrity in bEnd.3 cells by reducing tight junction proteins (ZO-1, Claudin-5, and Occludin) and upregulating adhesion molecules (VCAM-1 and ICAM-1). NNK exposure also triggered inflammatory activation in BV2 microglia, resulting in elevated expression of TNF-\u03b1, IL-1\u03b2, and IL-6. Importantly, DPP4 silencing partially restored endothelial junctional integrity and attenuated pro-adhesive signaling in endothelial cells while reducing inflammatory cytokine expression in microglia, suggesting that DPP4 is functionally involved in NNK-induced neurovascular inflammation. Together, these findings suggest that NNK exposure may modulate neuroinflammatory processes relevant to MS through blood-brain barrier (BBB) disruption and microglial activation, with DPP4 potentially being involved in this process. This study provides mechanistic insights into how smoking-associated toxins may influence MS progression and highlights DPP4-related pathways as potential targets for therapeutic investigation."

To our knowledge, n-hexane-toxic neuropathy presenting with a cauda equina-like syndrome has not previously been reported. CASE PRESENTATION: A 55-year-old man developed sensory and motor polyneuropathy over a 3-month period, with nerve conduction studies indicating demyelination. Initial treatment for suspected chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) with steroids and plasma exchange was ineffective, leading to worsening symptoms. The patient and his colleagues were found to have been habitually exposed to n-hexane in their printing work, and a sural nerve biopsy revealed the pathological findings typical of n-hexane-toxic neuropathy. Notably, cauda equina inflammation was observed on MRI and in the cerebrospinal fluid. Following intravenous immunoglobulin therapy, both neurological symptoms and findings from nerve conduction studies, MRI, and cerebrospinal fluid analysis gradually improved, eventually leading the absence of impairment in activities of daily living. CONCLUSION: In cases of polyneuropathy accompanied by inflammation of the cauda equina, and if exposure to n-hexane cannot be ruled out, sural nerve biopsy could be considered to assess for n-hexane-toxic neuropathy."

Exposure to 1-bromopropane for 4 weeks increased distal latency in the tail nerve significantly in F344 and marginally in WNA/NUM. It also increased total and direct bilirubin in both rat strains. Eight-hour exposure increased metallothionein 2A, metallothionein 1 and NAD(P)H quinone dehydrogenase 1 expression in the liver of both rat strains, whereas 4-week exposure upregulated glutathione S-transferase alpha 3 and CD36 molecule in the liver of both strains. KEGG analysis showed that 8-hr 1-bromopropane upregulated pathways of apoptosis, NOD-like receptor signaling and colorectal cancer, in both the hippocampus and liver, whereas 4-week exposure upregulated NOD-like receptor signaling pathway both in the hippocampus and liver of the two rat strains. Insulin signaling pathway was upregulated persistently in the hippocampus of the two rat strains.

The comparison tested how solvent polarity and hydrogen-bonding behavior affect product distribution under otherwise fixed conditions. FTIR, GPC, and GC-MS showed differences among the five soluble fractions. Protic solvents retained more phenolic monomers and oligomers, whereas aprotic solvents gave more oxidized products and different H:G:S profiles. The ethanol fraction had the highest apparent thermal stability (Ea\u00a0=\u00a04.14\u00a0kJ/mol; DTG peak\u00a0=\u00a0380\u00a0\u00b0C) and the lowest Mw (856\u00a0Da). Methyl cellosolve produced the highest-Mw fraction (2985\u00a0Da) and a more balanced H:G:S distribution. Guaiacol accounted for 40.6% of the ethanol fraction, coumaran for 70.4% of the THF fraction, and syringol for 17.2% of the methyl cellosolve fraction. THF-only controls did not produce a peak assigned to coumaran in the relevant retention-time window, which supports a lignin-derived origin for this signal under the tested conditions. The screening results link solvent properties to lignin fragmentation and the composition of the soluble products. Solvent recycling, residue characterization, process optimization, and atom-resolved mechanistic studies remain to be completed."

Network toxicology identified 252 shared targets between sleep-related environmental pollutants (SREPs: NO2, formaldehyde, benzene) and SD. PPI network and diagnostic model identified four hub genes (HSP90AA1, RELA, PTGS2, MMP9) with moderate-to-high predictive value (AUC: 0.708-0.979). Immune infiltration analysis showing elevated T cells and reduced astrocytes and neurons in patients with SD. Molecular simulations confirmed stable SREP-hub protein binding, with benzene exhibiting the highest affinity. Crucially, mixed SREPs exposure induced more severe toxicity than individual pollutants, demonstrating true synergistic disruption. In vivo, SREPs metabolites disrupted sleep architecture, impaired the blood-brain barrier (BBB), and induced neurobehavioral deficits. In vitro studies using brain endothelial cells (BMVECs) revealed that SREPs directly increase permeability, suppress tight junctions, and activate a pro-inflammatory cascade involving NF-\u03baB signaling, enhanced MMP9 activity, and prostaglandin E2 synthesis. Curcumin intervention effectively counteracted these effects, restoring BBB integrity, normalizing sleep patterns, and suppressing hub gene expression and neuroinflammation in vivo and in vitro by targeting the identified hub gene network.

This review summarizes current evidence evaluating how environmental exposures interact across the genome, epigenome, transcriptome, proteome, metabolome, and microbiome to drive ILD pathogenesis. Environmental exposures, including air pollution, influence ILD risk through interactions with genetic factors that modify disease susceptibility. Epigenetic mechanisms, particularly DNA methylation, reflect key pathways through which exposures may contribute to ILD onset and progression and serve as sensitive biomarkers of environmental injury. Exposure-associated molecular alterations can be detected across multiple omic layers, including transcriptomic, proteomic, and metabolomic profiles. In parallel, exposures like cigarette smoking, silica, and air pollution influence the respiratory microbiome, with potential downstream effects on immune responses and fibrogenesis. Integrating these findings highlights environmentally-sensitive pathways that may represent novel targets for therapeutic modulation. Integration of exposomic and multiomic molecular frameworks offers new opportunities to improve ILD risk stratification, prognostication, and precision therapeutic development, while also strengthening our mechanistic understanding of environmentally-mediated disease."

Although pesticides, industrial solvents, heavy metals, and air pollutants have long been implicated as potentially modifiable PD risk factors, climate change is now reshaping and amplifying these hazards through rising temperatures, worsening air quality, increased pesticide demand, extreme weather events, and wildfire-related particulate matter.This narrative review moves beyond a conventional exposure-based summary by integrating environmental toxicology, climate science, epidemiology, and mechanistic neuroscience to reframe PD risk within the context of planetary health. We summarize evidence linking major environmental hazards to PD pathogenesis, emphasizing convergent mechanisms such as oxidative stress, mitochondrial dysfunction, impaired proteostasis, neuroinflammation, blood-brain barrier disruption, and \u03b1-synuclein aggregation. We further discuss how climate-related changes may intensify these pathways and disproportionately affect vulnerable populations, including agricultural workers, older adults, socioeconomically disadvantaged communities, and individuals living in rapidly industrializing or climate-sensitive regions. Importantly, we highlight clinical and public health implications by proposing that structured environmental and occupational exposure assessment should be incorporated into PD risk evaluation, early recognition, preventive counseling, and research design. We also discuss exposure reduction, workplace protection, environmental monitoring, and regulatory policy as prevention-oriented strategies. By positioning environmental hazards and climate change as interconnected, underrecognized, and potentially modifiable contributors to PD, this review provides a framework for clinicians, researchers, and policymakers seeking to reduce the future global burden of neurodegenerative disease. Parkinson's disease (PD) is a common neurodegenerative disorder that develops over time and affects movement, balance, and many daily activities. While genes play a role, most cases of PD do not arise solely from genetics. Growing evidence shows that environmental exposures, such as pesticides, industrial chemicals, heavy metals, and air pollution, can increase the risk of developing PD. Importantly, many of these exposures can be reduced or prevented. Climate change is worsening these environmental risks. Higher temperatures, poorer air quality, increased pesticide use, and more frequent wildfires are increasing human exposure to harmful pollutants worldwide. Together, these changes may increase the number of people affected by PD, especially in communities already facing environmental or social disadvantages. This review explains how environmental toxins can damage brain cells through shared biological processes, including oxidative stress, inflammation, and abnormal protein buildup. It also highlights regions and populations that may be more vulnerable to these risks. From a healthcare perspective, understanding a person's environmental and work-related exposures can help identify those at higher risk, support earlier recognition of PD, and guide prevention advice. Overall, environmental toxins and climate change are underrecognized yet actionable determinants of PD. Increasing awareness, improving environmental protections, and integrating exposure history into clinical care are key steps toward reducing the future global burden of PD."

While aging and improved diagnostic awareness partly explain this trend, mounting evidence implicates environmental factors as critical contributors. This review synthesizes current literature on exposures such as pesticides, solvents, heavy metals, air pollutants, and infectious agents, emphasizing their mechanistic links to neurodegeneration. These factors interact with genetic susceptibility and aging, supporting the \"multiple-hit\" hypothesis, which posits that PD arises from cumulative insults rather than a single cause. Mitochondrial dysfunction, oxidative stress, neuroinflammation, and impaired protein clearance emerge as convergent pathways underlying dopaminergic vulnerability. Recent findings highlight viral infections-particularly SARS-CoV-2-as potential triggers or amplifiers of PD pathogenesis, raising concerns about long-term neurological sequelae following pandemics. Beyond individual toxins, the exposome concept underscores the lifelong interplay of physical, chemical, and social exposures in shaping disease risk. Climate-related changes, including increased air pollution and wildfire frequency, further compound these risks, suggesting a systemic dimension to PD etiology. Understanding these complex interactions is essential for developing preventive strategies, refining experimental models, and informing public health policies aimed at mitigating environmental contributions to neurodegeneration. This multifactorial perspective offers a foundation for future research targeting modifiable risk factors and resilience mechanisms in PD. Parkinson\u2019s disease (PD) is a brain disorder that affects movement and is becoming more common worldwide. While aging and genetics play a role, research shows that environmental factors\u2014such as pesticides, air pollution, industrial chemicals, and even certain infections\u2014may also increase the risk of developing PD. This article explains how these factors can damage brain cells over time. For example, pesticides and solvents can harm the parts of the brain that control movement. Air pollution and heavy metals may also contribute to brain inflammation and stress. Infections like influenza and COVID-19 could act as \u201ctriggers,\u201d making the brain more vulnerable to damage later in life. Scientists call this the \u201cmultiple-hit\u201d theory, meaning PD often results from a combination of aging, genes, and environmental exposures rather than a single cause. The review also introduces the concept of the \u201cexposome,\u201d which looks at all the things we are exposed to throughout life\u2014chemicals, air quality, diet, and even stress\u2014and how they interact with our biology. Understanding these links can help researchers find ways to prevent PD, improve treatments, and guide public health policies. In short, Parkinson\u2019s disease is not just about getting older or having certain genes. It may also be influenced by what we breathe, eat, and encounter in our environment. By studying these factors, we can work toward reducing risks and protecting brain health."

Glycol ethers consist in a widely used class of organic solvents leading to workers and consumers exposure via many applications. Ethylene glycol ethers are gradually being replaced by propylene glycol ethers thought to be less toxic. However, their neurotoxicity is not systematically assessed before placing them on the market. Therefore, this study investigated the potential neurotoxicity of propylene glycol butyl ether (PGBE) for which no official occupational limit has been established. To this aim, new approach methodologies have been used. Human induced pluripotent stem cells-derived BrainSpheres model was exposed to PGBE and to its assumed human main metabolite, 2-butoxypropanoic acid (2BPA). An integrative multiomic approach (transcriptomics, proteomics, metabolomics and lipidomics) was adopted to assess molecular alterations, derive benchmark concentrations and define potential mechanisms of action. PGBE was neurotoxic at occupationally relevant exposure concentrations. This was shown for the first time in human cells. Although PGBE was more cytotoxic than 2BPA, both compounds showed very similar neurotoxicity. PGBE and 2BPA strongly affected the cell cycle, induced oxidative stress and perturbed energy and lipid metabolism. They also targeted specific nervous system processes, such as axon guidance and synapse organization. Finally, 2BPA might trigger ferroptosis by increased iron uptake. Our in vitro results show an urgent need for public health authorities to carefully assess the risk glycol ethers pose to humans, to properly protect the workers as well as individuals in the general population unknowingly exposed from indoor air contaminations."

Key factors include vitamin D deficiency, low UV exposure, smoking, adolescent obesity, air pollution, and chemical environmental exposures. Mendelian randomization studies support the causality of several determinants, particularly low vitamin D and high BMI. Adolescence emerges as a critical susceptibility window where the maturing immune system is uniquely sensitive to metabolic and environmental triggers. Among validated interventions, vitamin D supplementation stands out for its ability to reduce disease activity in early MS. Effective prevention requires both individual actions and structural public health policies, such as air quality regulations and urban \"walkability\". Future efforts should prioritize multimodal strategies targeting high-risk youths through the educational system (physical activity, weight management, and smoking prevention). These holistic approaches offer broad-spectrum benefits, reducing the burden of MS while preventing comorbidities, including cardiovascular, metabolic but also cancer."

Nicotine-derived nitrosamine ketone (NNK), a potent tobacco-specific nitrosamine, has been implicated in MS; however, its mechanistic contribution to disease pathogenesis remains poorly understood. Here, we applied an integrative multi-level approach to investigate the potential role of NNK in MS. Mendelian randomization (MR) analysis identified genetically predicted dipeptidyl peptidase-4 (DPP4) activity as being associated with MS susceptibility. Molecular docking further demonstrated feasible interactions between NNK and candidate proteins, including DPP4, providing theoretical plausibility for chemical-protein interactions. In experimental autoimmune encephalomyelitis (EAE) mice, systemic NNK exposure accelerated disease onset, aggravated neurological deficits, and enhanced immune cell infiltration and demyelination within the central nervous system (CNS), accompanied by increased DPP4 expression in inflamed regions. Consistent with these observations, in vitro NNK treatment impaired endothelial barrier integrity in bEnd.3 cells by reducing tight junction proteins (ZO-1, Claudin-5, and Occludin) and upregulating adhesion molecules (VCAM-1 and ICAM-1). NNK exposure also triggered inflammatory activation in BV2 microglia, resulting in elevated expression of TNF-\u03b1, IL-1\u03b2, and IL-6. Importantly, DPP4 silencing partially restored endothelial junctional integrity and attenuated pro-adhesive signaling in endothelial cells while reducing inflammatory cytokine expression in microglia, suggesting that DPP4 is functionally involved in NNK-induced neurovascular inflammation. Together, these findings suggest that NNK exposure may modulate neuroinflammatory processes relevant to MS through blood-brain barrier (BBB) disruption and microglial activation, with DPP4 potentially being involved in this process. This study provides mechanistic insights into how smoking-associated toxins may influence MS progression and highlights DPP4-related pathways as potential targets for therapeutic investigation."

In this study, technical alkali lignin from soda bagasse was ozonated in ethanol, tetrahydrofuran (THF), 1,4-dioxane, acetone, or methyl cellosolve to combine oxidative depolymerization with solvent fractionation. The comparison tested how solvent polarity and hydrogen-bonding behavior affect product distribution under otherwise fixed conditions. FTIR, GPC, and GC-MS showed differences among the five soluble fractions. Protic solvents retained more phenolic monomers and oligomers, whereas aprotic solvents gave more oxidized products and different H:G:S profiles. The ethanol fraction had the highest apparent thermal stability (Ea\u00a0=\u00a04.14\u00a0kJ/mol; DTG peak\u00a0=\u00a0380\u00a0\u00b0C) and the lowest Mw (856\u00a0Da). Methyl cellosolve produced the highest-Mw fraction (2985\u00a0Da) and a more balanced H:G:S distribution. Guaiacol accounted for 40.6% of the ethanol fraction, coumaran for 70.4% of the THF fraction, and syringol for 17.2% of the methyl cellosolve fraction. THF-only controls did not produce a peak assigned to coumaran in the relevant retention-time window, which supports a lignin-derived origin for this signal under the tested conditions. The screening results link solvent properties to lignin fragmentation and the composition of the soluble products. Solvent recycling, residue characterization, process optimization, and atom-resolved mechanistic studies remain to be completed."

Network toxicology identified 252 shared targets between sleep-related environmental pollutants (SREPs: NO2, formaldehyde, benzene) and SD. PPI network and diagnostic model identified four hub genes (HSP90AA1, RELA, PTGS2, MMP9) with moderate-to-high predictive value (AUC: 0.708-0.979). Immune infiltration analysis showing elevated T cells and reduced astrocytes and neurons in patients with SD. Molecular simulations confirmed stable SREP-hub protein binding, with benzene exhibiting the highest affinity. Crucially, mixed SREPs exposure induced more severe toxicity than individual pollutants, demonstrating true synergistic disruption. In vivo, SREPs metabolites disrupted sleep architecture, impaired the blood-brain barrier (BBB), and induced neurobehavioral deficits. In vitro studies using brain endothelial cells (BMVECs) revealed that SREPs directly increase permeability, suppress tight junctions, and activate a pro-inflammatory cascade involving NF-\u03baB signaling, enhanced MMP9 activity, and prostaglandin E2 synthesis. Curcumin intervention effectively counteracted these effects, restoring BBB integrity, normalizing sleep patterns, and suppressing hub gene expression and neuroinflammation in vivo and in vitro by targeting the identified hub gene network. Our integrated computational-experimental strategy establishes a novel \"pollutant-BBB-neuroimmune-sleep\" axis, providing a mechanistic framework for assessing cumulative environmental risks and advancing targeted interventions."

It was first documented in Shen Nong's Herbal Classic for its efficacy in dispersing cold, relieving pain, and alleviating nausea, vomiting, and diarrhea, leading to its historical use in managing gastrointestinal ailments. However, the clinical application of EF has been limited due to its associated hepatotoxicity. Existing studies have confirmed that evodiamine, rutaecarpine and other alkaloids induce hepatotoxicity via multi-pathways, but the core toxic fraction, multi-component synergistic effects and systematic toxic network of EF remain unclear. This study aims to identify the key hepatotoxic fraction of Evodiae Fructus (EF) and elucidate its underlying mechanisms. A high-throughput zebrafish model was used to screen EF extracts with different polar solvents. The hepatotoxicity of the target fraction was validated in mice. UPLC-Q-TOF-MS/MS, integrated network pharmacology, proteomic and transcriptomic analyses were performed in zebrafish and mice to screen toxic pathways, with western blot and qRT-PCR validation. High-throughput zebrafish screening of five polar extracts of EF identified the dichloromethane extract (DEEF) as the core hepatotoxic fraction. Both zebrafish and mouse models consistently indicated that DEEF induced a dose-dependent elevation of serum ALT, AST, and TBA levels, disrupted the architecture of hepatic tissue, and was accompanied by marked hepatocyte apoptosis. In mice, Masson's trichrome staining further revealed abnormal collagen deposition, along with extensive infiltration of inflammatory cells. UPLC-Q-TOF-MS/MS analysis identified 73 compounds in DEEF, with 48 alkaloids (indole and quinolone types) being the dominant components, in addition to flavonoids, limonoids, and organic acids. Integrated network pharmacology, transcriptomic and proteomic analyses revealed dose-dependent global alterations in hepatic gene and protein expression profiles.

Cumulative lifetime exposures (i.e. the exposome) contribute to ILD onset and progression by interacting with genetic susceptibility and influencing multiple molecular pathways. This review summarizes current evidence evaluating how environmental exposures interact across the genome, epigenome, transcriptome, proteome, metabolome, and microbiome to drive ILD pathogenesis. Environmental exposures, including air pollution, influence ILD risk through interactions with genetic factors that modify disease susceptibility. Epigenetic mechanisms, particularly DNA methylation, reflect key pathways through which exposures may contribute to ILD onset and progression and serve as sensitive biomarkers of environmental injury. Exposure-associated molecular alterations can be detected across multiple omic layers, including transcriptomic, proteomic, and metabolomic profiles. In parallel, exposures like cigarette smoking, silica, and air pollution influence the respiratory microbiome, with potential downstream effects on immune responses and fibrogenesis. Integrating these findings highlights environmentally-sensitive pathways that may represent novel targets for therapeutic modulation. Integration of exposomic and multiomic molecular frameworks offers new opportunities to improve ILD risk stratification, prognostication, and precision therapeutic development, while also strengthening our mechanistic understanding of environmentally-mediated disease."

Although pesticides, industrial solvents, heavy metals, and air pollutants have long been implicated as potentially modifiable PD risk factors, climate change is now reshaping and amplifying these hazards through rising temperatures, worsening air quality, increased pesticide demand, extreme weather events, and wildfire-related particulate matter.This narrative review moves beyond a conventional exposure-based summary by integrating environmental toxicology, climate science, epidemiology, and mechanistic neuroscience to reframe PD risk within the context of planetary health. We summarize evidence linking major environmental hazards to PD pathogenesis, emphasizing convergent mechanisms such as oxidative stress, mitochondrial dysfunction, impaired proteostasis, neuroinflammation, blood-brain barrier disruption, and \u03b1-synuclein aggregation. We further discuss how climate-related changes may intensify these pathways and disproportionately affect vulnerable populations, including agricultural workers, older adults, socioeconomically disadvantaged communities, and individuals living in rapidly industrializing or climate-sensitive regions. Importantly, we highlight clinical and public health implications by proposing that structured environmental and occupational exposure assessment should be incorporated into PD risk evaluation, early recognition, preventive counseling, and research design. We also discuss exposure reduction, workplace protection, environmental monitoring, and regulatory policy as prevention-oriented strategies. By positioning environmental hazards and climate change as interconnected, underrecognized, and potentially modifiable contributors to PD, this review provides a framework for clinicians, researchers, and policymakers seeking to reduce the future global burden of neurodegenerative disease. Parkinson's disease (PD) is a common neurodegenerative disorder that develops over time and affects movement, balance, and many daily activities. While genes play a role, most cases of PD do not arise solely from genetics. Growing evidence shows that environmental exposures, such as pesticides, industrial chemicals, heavy metals, and air pollution, can increase the risk of developing PD. Importantly, many of these exposures can be reduced or prevented. Climate change is worsening these environmental risks. Higher temperatures, poorer air quality, increased pesticide use, and more frequent wildfires are increasing human exposure to harmful pollutants worldwide. Together, these changes may increase the number of people affected by PD, especially in communities already facing environmental or social disadvantages. This review explains how environmental toxins can damage brain cells through shared biological processes, including oxidative stress, inflammation, and abnormal protein buildup. It also highlights regions and populations that may be more vulnerable to these risks. From a healthcare perspective, understanding a person's environmental and work-related exposures can help identify those at higher risk, support earlier recognition of PD, and guide prevention advice. Overall, environmental toxins and climate change are underrecognized yet actionable determinants of PD. Increasing awareness, improving environmental protections, and integrating exposure history into clinical care are key steps toward reducing the future global burden of PD."

While aging and improved diagnostic awareness partly explain this trend, mounting evidence implicates environmental factors as critical contributors. This review synthesizes current literature on exposures such as pesticides, solvents, heavy metals, air pollutants, and infectious agents, emphasizing their mechanistic links to neurodegeneration. These factors interact with genetic susceptibility and aging, supporting the \"multiple-hit\" hypothesis, which posits that PD arises from cumulative insults rather than a single cause. Mitochondrial dysfunction, oxidative stress, neuroinflammation, and impaired protein clearance emerge as convergent pathways underlying dopaminergic vulnerability. Recent findings highlight viral infections-particularly SARS-CoV-2-as potential triggers or amplifiers of PD pathogenesis, raising concerns about long-term neurological sequelae following pandemics. Beyond individual toxins, the exposome concept underscores the lifelong interplay of physical, chemical, and social exposures in shaping disease risk. Climate-related changes, including increased air pollution and wildfire frequency, further compound these risks, suggesting a systemic dimension to PD etiology. Understanding these complex interactions is essential for developing preventive strategies, refining experimental models, and informing public health policies aimed at mitigating environmental contributions to neurodegeneration. This multifactorial perspective offers a foundation for future research targeting modifiable risk factors and resilience mechanisms in PD. Parkinson\u2019s disease (PD) is a brain disorder that affects movement and is becoming more common worldwide. While aging and genetics play a role, research shows that environmental factors\u2014such as pesticides, air pollution, industrial chemicals, and even certain infections\u2014may also increase the risk of developing PD. This article explains how these factors can damage brain cells over time. For example, pesticides and solvents can harm the parts of the brain that control movement. Air pollution and heavy metals may also contribute to brain inflammation and stress. Infections like influenza and COVID-19 could act as \u201ctriggers,\u201d making the brain more vulnerable to damage later in life. Scientists call this the \u201cmultiple-hit\u201d theory, meaning PD often results from a combination of aging, genes, and environmental exposures rather than a single cause. The review also introduces the concept of the \u201cexposome,\u201d which looks at all the things we are exposed to throughout life\u2014chemicals, air quality, diet, and even stress\u2014and how they interact with our biology. Understanding these links can help researchers find ways to prevent PD, improve treatments, and guide public health policies. In short, Parkinson\u2019s disease is not just about getting older or having certain genes. It may also be influenced by what we breathe, eat, and encounter in our environment. By studying these factors, we can work toward reducing risks and protecting brain health."

Glycol ethers consist in a widely used class of organic solvents leading to workers and consumers exposure via many applications. Ethylene glycol ethers are gradually being replaced by propylene glycol ethers thought to be less toxic. However, their neurotoxicity is not systematically assessed before placing them on the market. Therefore, this study investigated the potential neurotoxicity of propylene glycol butyl ether (PGBE) for which no official occupational limit has been established. To this aim, new approach methodologies have been used. Human induced pluripotent stem cells-derived BrainSpheres model was exposed to PGBE and to its assumed human main metabolite, 2-butoxypropanoic acid (2BPA). An integrative multiomic approach (transcriptomics, proteomics, metabolomics and lipidomics) was adopted to assess molecular alterations, derive benchmark concentrations and define potential mechanisms of action. PGBE was neurotoxic at occupationally relevant exposure concentrations. This was shown for the first time in human cells. Although PGBE was more cytotoxic than 2BPA, both compounds showed very similar neurotoxicity. PGBE and 2BPA strongly affected the cell cycle, induced oxidative stress and perturbed energy and lipid metabolism. They also targeted specific nervous system processes, such as axon guidance and synapse organization. Finally, 2BPA might trigger ferroptosis by increased iron uptake. Our in vitro results show an urgent need for public health authorities to carefully assess the risk glycol ethers pose to humans, to properly protect the workers as well as individuals in the general population unknowingly exposed from indoor air contaminations."

This review examines modifiable non-infectious determinants across the life course and proposes integrated prevention strategies. Key factors include vitamin D deficiency, low UV exposure, smoking, adolescent obesity, air pollution, and chemical environmental exposures. Mendelian randomization studies support the causality of several determinants, particularly low vitamin D and high BMI. Adolescence emerges as a critical susceptibility window where the maturing immune system is uniquely sensitive to metabolic and environmental triggers. Among validated interventions, vitamin D supplementation stands out for its ability to reduce disease activity in early MS. Effective prevention requires both individual actions and structural public health policies, such as air quality regulations and urban \"walkability\". Future efforts should prioritize multimodal strategies targeting high-risk youths through the educational system (physical activity, weight management, and smoking prevention). These holistic approaches offer broad-spectrum benefits, reducing the burden of MS while preventing comorbidities, including cardiovascular, metabolic but also cancer."

To investigate associations between retrospective lifetime shift work exposure and MS diagnosis and between prospective shift work exposure and incident MS over 13 years of follow-up in the UK Biobank cohort. Participants that were in work and free of MS at baseline were followed up for 13 years, and lifetime exposure to night, day and mixed shift work was assessed in a subset of participants. Logistic regression and Cox proportional hazard models were applied to test associations between shift work and MS diagnosis, controlling for demographic and lifestyle confounders.

Similarly, epidemiological studies implicate numerous environmental risk factors in MS risk, but these cannot identify specific causal mechanisms. We review our current knowledge of genetic mechanisms in MS, including the critical role of expression quantitative trait locus (eQTL) mapping in translating genetic risk loci into causal mechanisms. Molecular and functional context has emerged as an important missing component of these studies, and we discuss how environmental risk factors can be modelled in a quantitative genetic context to identify disease mechanisms. In parallel, we highlight recent advances in which quantitative genetic methods establish a causal role for low vitamin D and obesity in MS, and to dissect the mechanisms through which these operate. As genetic, transcriptional, and epigenetic studies continue to expand, further mechanistic insights for MS are likely to come from the integration of genetic and environmental data."

Therefore, continuous doping control is essential for maintaining fairness and athlete's safety. Accurate and rapid detection of prohibited substances at their lowest levels in complex biological matrices, such as blood, urine, and plasma, is crucial for reliable anti-doping analysis. This critical review focuses on the applications of mass spectrometry (MS) for the detection of doping agents across diverse biological matrices. Special emphasis is given to advanced mass spectrometry platforms, particularly LC-QQQ-MS, LC-QTOF-MS, Orbitrap-MS/MS, and IRMS which are widely used for the routine screening, confirmation, and identification of emerging doping agents. Microsampling approaches such as dried blood spots (DBS) and volumetric absorptive microsampling (VAMS) provide superior alternatives to traditional sampling. Furthermore, comprehensive understanding of sample pretreatment and analytical techniques is essential. In this regard, novel microextraction techniques, including solid-phase microextraction (SPME), liquid-phase microextraction (LPME), supramolecular solvents (SUPRAS), and deep eutectic solvents (DES), have improved multi-analyte sample pretreatment strategies and facilitated advanced automation. This review also offers valuable guidance in selecting appropriate chromatography coupled mass spectrometry\u2011based analytical methods with sensitive detection, sample pretreatment techniques, and storage conditions during sports drug testing."

Their reliable determination depends strongly on efficient sample preparation, but conventional organic solvent extraction often raises concerns related to solvent consumption, toxicity, selectivity, and sample-cleanup burden. Deep eutectic solvents (DESs) have been widely explored as tunable extraction media for phenolic compounds because their polarity, viscosity, hydrogen-bonding capacity, and solvation behavior can be adjusted by changing the hydrogen-bond acceptor, hydrogen-bond donor, molar ratio, and water content. However, conventional DES systems still face important limitations, including slow mass transfer caused by high viscosity, difficulty in solvent removal due to low volatility, incomplete analyte recovery, and possible interference with chromatographic or mass-spectrometric analysis. This review summarizes conventional DES-based extraction of phenolic compounds as the baseline, and then focuses on responsive switchable DESs (RS-DESs) as recovery-oriented solvent systems. RS-DESs can undergo reversible changes in phase behavior, polarity, miscibility, or solvation ability in response to temperature, pH, CO2/N2, or ionic strength, thereby facilitating extraction, phase separation, analyte recovery, and solvent recycling. Particular attention is paid to extraction mechanisms, structure-property relationships, quantitative comparison with conventional DES systems, and analytical compatibility with HPLC, LC-MS, and related sample-cleanup workflows. Finally, the review discusses current scientific, analytical, and industrial challenges, including switching reproducibility, phenolic stability, DES residues, matrix effects, toxicity, biodegradability, and scale-up feasibility."

Epstein-Barr virus (EBV) infection has been implicated as a major environmental risk factor in MS pathogenesis. Despite the availability of disease-modifying therapies, effective targeted interventions for progressive disease remain limited. In this study, an EBV-informed integrative computational framework combining MS transcriptomic datasets, EBV-associated transcriptional signatures, GWAS susceptibility genes, and network analyses was employed to identify molecular targets associated with immune dysregulation in MS. RNA-sequencing datasets related to MS and EBV infection were obtained from the GEO database, whereas MS susceptibility genes were retrieved from the GWAS Catalog. Differential expression analysis identified 275, 200, and 773 significant DEGs in CD4\u207a T cells, CD8\u207a T cells, and CD14\u207a monocytes, respectively, along with 8,633 EBV-associated DEGs. Integrative overlap and enrichment analyses revealed convergence at the pathway level, particularly involving B-cell receptor signaling, Fc receptor activation, antigen presentation, complement activation, and inflammatory immune signaling. Hub gene analysis identified IL6, CD86, CD28, and PTPN11 as central regulatory nodes. Based on biological relevance and structural tractability, PTPN11/SHP2 was selected as the final therapeutic target. Structure-based drug repurposing identified Gusperimus as the top-ranked ligand, exhibiting a favorable docking score (-\u20099.287\u00a0kcal/mol) and a broader interaction profile within the SHP2 allosteric pocket relative to the reference inhibitor SHP099 (-\u20097.915\u00a0kcal/mol). Molecular dynamics simulations supported stable occupancy of the SHP2 allosteric pocket by Gusperimus over a 100 ns trajectory. Collectively, these findings highlight SHP2 as a potential therapeutic target and identify Gusperimus as a candidate for further investigation in MS-associated immune dysregulation."

Cross-sectional analysis of a multicentre prospective registry. Six German Social Accident Insurance hospitals distributed across Germany, providing standardised post-COVID assessments for individuals with persistent symptoms following occupational SARS-CoV-2 infection. Workers with confirmed SARS-CoV-2 infection recognised as an occupational disease or work-related accident who presented with persistent symptoms and were enrolled in a multicentre post-COVID registry. Cognitive and physical fatigue severity assessed using validated self-administered questionnaires (Fatigue Scale for Motor and Cognitive Functions, Modified Fatigue Impact Scale and W\u00fcrzburg Fatigue Inventory for Multiple Sclerosis). Clinical relevance was determined based on established cut-offs reported in the literature. Fatigue severity was operationalised using median splits of the respective subscales to identify factors associated with higher fatigue levels. Among 1511 registry cases, 628 participants had complete fatigue data. Median age was 54 years, 77% were female and most worked in nursing (43%) or educational/care professions (19%). Clinically relevant fatigue was highly prevalent: cognitive fatigue affected 78%-93% and physical fatigue 87%-98%. Both fatigue dimensions were positively correlated with older age, work incapacity and persistent symptom burden. In multivariate analyses, a higher number of acute symptoms was associated with lower odds of cognitive fatigue (adjusted OR 0.39, 95%\u2009CI 0.19 to 0.81), while physical fatigue remained associated with profession (adjusted OR 2.04, 95%\u2009CI 1.17 to 3.59). Sex, pre-existing conditions, hospitalisation and variant wave were not significant predictors in either model. Fatigue is a prevalent and disabling PCS-symptom among occupationally exposed workers. Distinct determinants of cognitive and physical fatigue emphasise the need for early recognition, targeted management and rehabilitation strategies to support recovery and work reintegration."

Black carbon (BC), a carbonaceous particulate generated through the incomplete combustion of fossil fuels, biomass, and biofuels, is recognized as a major short-lived climate pollutant with significant implications for atmospheric processes and agricultural sustainability. Unlike engineered biochar, atmospheric BC acts as an environmental stressor through deposition on plant surfaces and accumulation in agroecosystems, yet its direct impacts on crop physiology remain insufficiently understood. This review synthesizes current knowledge on the physicochemical characteristics, environmental pathways, and plant stress mechanisms associated with atmospheric BC while explicitly distinguishing it from intentionally applied biochar. Available evidence indicates that BC influences plant performance through multiple interconnected pathways, including reduced light availability, stomatal obstruction, disruption of photosynthesis, oxidative stress induced by excessive reactive oxygen species (ROS), chloroplast dysfunction, hormonal imbalance, and alterations in nutrient cycling and soil microbial communities. However, much of the mechanistic evidence is derived from studies on biochar, carbon nanomaterials, or other particulate pollutants, highlighting a critical gap in plant-specific evidence under realistic atmospheric BC exposure. Regional studies, particularly from the Indo-Gangetic Plain, demonstrate that elevated BC and associated aerosol loading contribute to reduced crop productivity and increased food security risks, although these impacts often reflect the combined influence of multiple atmospheric stressors rather than BC alone. The review further examines current limitations in BC exposure quantification, emphasizing the absence of agronomic dose-response thresholds and standardized field-based assessment methods. Emerging approaches, including leaf-based biomonitoring and isotopic analyses, are discussed as promising tools for future exposure assessment. Finally, key research priorities are identified, including the generation of plant-specific mechanistic evidence, development of realistic dose-response frameworks, integration of BC into crop simulation models, and implementation of long-term field studies to improve risk assessment and support evidence-based mitigation strategies for sustainable agriculture."

This study aimed to pool the prevalence and concentration of antimicrobial and pesticide residues in Bangladeshi ASFs and to estimate dietary exposure and risk using deterministic and probabilistic frameworks benchmarked against health-based guidance values. Following PRISMA 2020, five databases were searched from January 2010 to April 2026. Random-effects models (Freeman-Tukey transformation, DerSimonian-Laird estimator) pooled prevalence across five matrices. Estimated daily intakes were combined with national consumption data and JECFA/JMPR acceptable daily intakes (ADIs) to derive hazard quotients (HQs), a cumulative hazard index (HI) and margins of exposure (MOE); a 10,000-iteration Monte-Carlo simulation characterized high-consumer (P95) exposure. Thirty-five studies (5,255 samples) were analyzed. Pooled prevalence was 12.9% (95% CI 8.8-17.6; I2\u00a0=\u00a095.8%), highest in farmed fish (40.3%) and lowest in eggs (4.7%); tetracyclines, fluoroquinolones, and organochlorines predominated. For the average adult, all HQs were \u226a1 and the cumulative HI was 0.031; heptachlor and dieldrin dominated (P95 %ADI 6.2 and 4.7). The child HI (\u22480.062) remained below unity; chloramphenicol P95 MOE fell to 253. Central-tendency dietary risk is low, but high-consumer tails, cumulative exposure, prohibited-substance detection and small-study effects justify strengthened, Codex-aligned residue surveillance, withdrawal-period enforcement and risk-based national monitoring within a One-Health framework."

Growing evidence indicates that nutrition, environment, and lifestyle significantly influence disease development, progression, and treatment response. Nutrients such as vitamins, minerals, omega-3 fatty acids, and polyphenols affect neuroinflammation, oxidative stress, mitochondrial health, and neurotransmitter function. Dietary patterns like the Mediterranean and ketogenic diets offer protective benefits in clinical and experimental contexts. Meanwhile, environmental neurotoxicants-air pollution, heavy metals, pesticides, and endocrine disruptors contribute to neurodegeneration via oxidative damage, synaptic impairment, and epigenetic alterations. Lifestyle factors, such as physical activity, sleep, stress, and substance use, affect brain plasticity, neurogenesis, and metabolic health, thereby influencing disease progression over time. These factors often share common pathways such as oxidative stress, inflammation, vascular injury, mitochondrial dysfunction, and protein misfolding, underscoring the need for a comprehensive prevention and treatment strategy. Emerging therapies now incorporate personalized nutrition, lifestyle changes, and environmental risk mitigation alongside traditional drugs, supported by advances in multi-omics, digital health, and systems biology. Public health efforts to reduce neurotoxic exposure and encourage healthy habits further strengthen these approaches. This review summarizes existing mechanistic and clinical knowledge, with a focus on the potential of nutritional, environmental, and lifestyle interventions in neurological diseases. It also outlines the future research required to enhance precision neurology and strategies for brain health prevention."

Based on the UK Biobank as the primary cohort, long-term air pollution exposure\u00a0(per standard deviation\u00a0increase) is associated with an increased risk of\u00a0AS, with HRs and 95% CIs of 1.60 (1.55,1.66) for PM2.5, 1.37 (1.32, 1.41) for PM10, 1.37 (1.32, 1.42) for NO2, and 1.36 (1.31, 1.41) for NOx. The observed associations demonstrate high consistency across a suite of advanced internal methodological validations and are further replicated in the Tianshan Community Cohort. There are joint and interactive effects of genetic susceptibility and air pollutants on AS risk. Network toxicology and bioinformatics analyses reveal key PM-AS target genes enriched in the lipid and atherosclerosis, fluid shear stress and atherosclerosis, and IL-17 signaling pathway.

Environmental risk factors, such as vitamin D deficiency and obesity, have also been implicated in multiple sclerosis pathogenesis. Statistical approaches building on these genetic data, such as Mendelian randomization and co-localization, have established putative causal links between environmental risk factors and multiple sclerosis risk, most notably for vitamin D and body mass index. However, studies have thus far revealed limited statistically significant interactions between host genetics and environmental factors beyond the major histocompatibility complex. Epigenetics (the study of non-nucleotide alterations to DNA, such as DNA methylation or histone acetylation) might provide a mechanistic framework for understanding how environmental and genetic factors interact in multiple sclerosis. Environmental factors, such as Epstein-Barr virus infection, vitamin D deficiency and smoking, are associated with epigenetic modifications at key multiple sclerosis-related genomic loci, altering the expression of multiple sclerosis risk genes in a cell type-specific manner. Transcriptomics have identified significant pathways via which genetic risk is realized, potentially providing targets for intervention. This review synthesizes current evidence on gene-environment interactions in the context of multiple sclerosis genome-wide association study findings, evaluates the strengths and limitations of various study methodologies, and discusses the challenges in elucidating the interplay between genetics and environmental factors. We propose potential strategies for future research to advance our understanding of the biological mechanisms underlying multiple sclerosis susceptibility in at-risk individuals."

In this study, technical alkali lignin from soda bagasse was ozonated in ethanol, tetrahydrofuran (THF), 1,4-dioxane, acetone, or methyl cellosolve to combine oxidative depolymerization with solvent fractionation. The comparison tested how solvent polarity and hydrogen-bonding behavior affect product distribution under otherwise fixed conditions. FTIR, GPC, and GC-MS showed differences among the five soluble fractions. Protic solvents retained more phenolic monomers and oligomers, whereas aprotic solvents gave more oxidized products and different H:G:S profiles. The ethanol fraction had the highest apparent thermal stability (Ea\u00a0=\u00a04.14\u00a0kJ/mol; DTG peak\u00a0=\u00a0380\u00a0\u00b0C) and the lowest Mw (856\u00a0Da). Methyl cellosolve produced the highest-Mw fraction (2985\u00a0Da) and a more balanced H:G:S distribution. Guaiacol accounted for 40.6% of the ethanol fraction, coumaran for 70.4% of the THF fraction, and syringol for 17.2% of the methyl cellosolve fraction. THF-only controls did not produce a peak assigned to coumaran in the relevant retention-time window, which supports a lignin-derived origin for this signal under the tested conditions. The screening results link solvent properties to lignin fragmentation and the composition of the soluble products. Solvent recycling, residue characterization, process optimization, and atom-resolved mechanistic studies remain to be completed."

Aquatic foods are important components of dietary diversification, but their association with internal PFAS burden remains unclear in inland populations. Of the 1294 participants initially recruited, 1292 with complete demographic information were included in the final analyses. Serum concentrations of 22 PFASs were measured by solid-phase extraction coupled with UPLC-MS/MS, and nine PFASs detected in more than 75% of samples were analyzed. Dietary intake frequency, sociodemographic characteristics, and lifestyle factors were collected using structured questionnaires. Multivariable linear regression and sex-stratified analyses were performed. Seafood-related food groups showed the most consistent positive associations with serum PFAS levels. Frequent consumption of shellfish, shrimp, crabs, fish, and seaweed was associated with higher concentrations of long-chain PFASs, including PFDA, PFNA, PFHxS, PFOS, and PFOA, while shrimp and crab intake was also positively associated with 6:2 Cl-PFESA. These associations were generally stronger in males, suggesting sex-related heterogeneity in the relationship between seafood intake and PFAS body burden. These findings suggest that seafood consumption is associated with distinct PFAS body-burden profiles in inland adults and may support integrated biomonitoring, dietary assessment, and food-contaminant surveillance."

This review examines modifiable non-infectious determinants across the life course and proposes integrated prevention strategies. Key factors include vitamin D deficiency, low UV exposure, smoking, adolescent obesity, air pollution, and chemical environmental exposures. Mendelian randomization studies support the causality of several determinants, particularly low vitamin D and high BMI. Adolescence emerges as a critical susceptibility window where the maturing immune system is uniquely sensitive to metabolic and environmental triggers. Among validated interventions, vitamin D supplementation stands out for its ability to reduce disease activity in early MS. Effective prevention requires both individual actions and structural public health policies, such as air quality regulations and urban \"walkability\". Future efforts should prioritize multimodal strategies targeting high-risk youths through the educational system (physical activity, weight management, and smoking prevention). These holistic approaches offer broad-spectrum benefits, reducing the burden of MS while preventing comorbidities, including cardiovascular, metabolic but also cancer."

Therefore, continuous doping control is essential for maintaining fairness and athlete's safety. Accurate and rapid detection of prohibited substances at their lowest levels in complex biological matrices, such as blood, urine, and plasma, is crucial for reliable anti-doping analysis. This critical review focuses on the applications of mass spectrometry (MS) for the detection of doping agents across diverse biological matrices. Special emphasis is given to advanced mass spectrometry platforms, particularly LC-QQQ-MS, LC-QTOF-MS, Orbitrap-MS/MS, and IRMS which are widely used for the routine screening, confirmation, and identification of emerging doping agents. Microsampling approaches such as dried blood spots (DBS) and volumetric absorptive microsampling (VAMS) provide superior alternatives to traditional sampling. Furthermore, comprehensive understanding of sample pretreatment and analytical techniques is essential. In this regard, novel microextraction techniques, including solid-phase microextraction (SPME), liquid-phase microextraction (LPME), supramolecular solvents (SUPRAS), and deep eutectic solvents (DES), have improved multi-analyte sample pretreatment strategies and facilitated advanced automation. This review also offers valuable guidance in selecting appropriate chromatography coupled mass spectrometry\u2011based analytical methods with sensitive detection, sample pretreatment techniques, and storage conditions during sports drug testing."

Their reliable determination depends strongly on efficient sample preparation, but conventional organic solvent extraction often raises concerns related to solvent consumption, toxicity, selectivity, and sample-cleanup burden. Deep eutectic solvents (DESs) have been widely explored as tunable extraction media for phenolic compounds because their polarity, viscosity, hydrogen-bonding capacity, and solvation behavior can be adjusted by changing the hydrogen-bond acceptor, hydrogen-bond donor, molar ratio, and water content. However, conventional DES systems still face important limitations, including slow mass transfer caused by high viscosity, difficulty in solvent removal due to low volatility, incomplete analyte recovery, and possible interference with chromatographic or mass-spectrometric analysis. This review summarizes conventional DES-based extraction of phenolic compounds as the baseline, and then focuses on responsive switchable DESs (RS-DESs) as recovery-oriented solvent systems. RS-DESs can undergo reversible changes in phase behavior, polarity, miscibility, or solvation ability in response to temperature, pH, CO2/N2, or ionic strength, thereby facilitating extraction, phase separation, analyte recovery, and solvent recycling. Particular attention is paid to extraction mechanisms, structure-property relationships, quantitative comparison with conventional DES systems, and analytical compatibility with HPLC, LC-MS, and related sample-cleanup workflows. Finally, the review discusses current scientific, analytical, and industrial challenges, including switching reproducibility, phenolic stability, DES residues, matrix effects, toxicity, biodegradability, and scale-up feasibility."

Epstein-Barr virus (EBV) infection has been implicated as a major environmental risk factor in MS pathogenesis. Despite the availability of disease-modifying therapies, effective targeted interventions for progressive disease remain limited. In this study, an EBV-informed integrative computational framework combining MS transcriptomic datasets, EBV-associated transcriptional signatures, GWAS susceptibility genes, and network analyses was employed to identify molecular targets associated with immune dysregulation in MS. RNA-sequencing datasets related to MS and EBV infection were obtained from the GEO database, whereas MS susceptibility genes were retrieved from the GWAS Catalog. Differential expression analysis identified 275, 200, and 773 significant DEGs in CD4\u207a T cells, CD8\u207a T cells, and CD14\u207a monocytes, respectively, along with 8,633 EBV-associated DEGs. Integrative overlap and enrichment analyses revealed convergence at the pathway level, particularly involving B-cell receptor signaling, Fc receptor activation, antigen presentation, complement activation, and inflammatory immune signaling. Hub gene analysis identified IL6, CD86, CD28, and PTPN11 as central regulatory nodes. Based on biological relevance and structural tractability, PTPN11/SHP2 was selected as the final therapeutic target. Structure-based drug repurposing identified Gusperimus as the top-ranked ligand, exhibiting a favorable docking score (-\u20099.287\u00a0kcal/mol) and a broader interaction profile within the SHP2 allosteric pocket relative to the reference inhibitor SHP099 (-\u20097.915\u00a0kcal/mol). Molecular dynamics simulations supported stable occupancy of the SHP2 allosteric pocket by Gusperimus over a 100 ns trajectory. Collectively, these findings highlight SHP2 as a potential therapeutic target and identify Gusperimus as a candidate for further investigation in MS-associated immune dysregulation."

Here, we review current evidence for the involvement of EBV in MS, its impact on existing therapeutics, and strategies for novel therapeutic directions. Compelling evidence indicates EBV infection precedes MS onset, likely contributing to disease initiation, relapses, and possibly progression through mechanisms such as molecular mimicry, B cell immortalization, and viral reactivation. Current MS therapies may indirectly suppress EBV by depleting B cells or restricting lymphocyte CNS entry. Novel strategies, including CAR-T/-NK cells, adoptive T cells, \"kick and kill\" approaches, and vaccines, aim to directly target EBV and offer promising new avenues for MS therapy."

Cross-sectional analysis of a multicentre prospective registry. Six German Social Accident Insurance hospitals distributed across Germany, providing standardised post-COVID assessments for individuals with persistent symptoms following occupational SARS-CoV-2 infection. Workers with confirmed SARS-CoV-2 infection recognised as an occupational disease or work-related accident who presented with persistent symptoms and were enrolled in a multicentre post-COVID registry. Cognitive and physical fatigue severity assessed using validated self-administered questionnaires (Fatigue Scale for Motor and Cognitive Functions, Modified Fatigue Impact Scale and W\u00fcrzburg Fatigue Inventory for Multiple Sclerosis). Clinical relevance was determined based on established cut-offs reported in the literature. Fatigue severity was operationalised using median splits of the respective subscales to identify factors associated with higher fatigue levels. Among 1511 registry cases, 628 participants had complete fatigue data. Median age was 54 years, 77% were female and most worked in nursing (43%) or educational/care professions (19%). Clinically relevant fatigue was highly prevalent: cognitive fatigue affected 78%-93% and physical fatigue 87%-98%. Both fatigue dimensions were positively correlated with older age, work incapacity and persistent symptom burden. In multivariate analyses, a higher number of acute symptoms was associated with lower odds of cognitive fatigue (adjusted OR 0.39, 95%\u2009CI 0.19 to 0.81), while physical fatigue remained associated with profession (adjusted OR 2.04, 95%\u2009CI 1.17 to 3.59). Sex, pre-existing conditions, hospitalisation and variant wave were not significant predictors in either model. Fatigue is a prevalent and disabling PCS-symptom among occupationally exposed workers. Distinct determinants of cognitive and physical fatigue emphasise the need for early recognition, targeted management and rehabilitation strategies to support recovery and work reintegration."

This study aimed to pool the prevalence and concentration of antimicrobial and pesticide residues in Bangladeshi ASFs and to estimate dietary exposure and risk using deterministic and probabilistic frameworks benchmarked against health-based guidance values. Following PRISMA 2020, five databases were searched from January 2010 to April 2026. Random-effects models (Freeman-Tukey transformation, DerSimonian-Laird estimator) pooled prevalence across five matrices. Estimated daily intakes were combined with national consumption data and JECFA/JMPR acceptable daily intakes (ADIs) to derive hazard quotients (HQs), a cumulative hazard index (HI) and margins of exposure (MOE); a 10,000-iteration Monte-Carlo simulation characterized high-consumer (P95) exposure. Thirty-five studies (5,255 samples) were analyzed. Pooled prevalence was 12.9% (95% CI 8.8-17.6; I2\u00a0=\u00a095.8%), highest in farmed fish (40.3%) and lowest in eggs (4.7%); tetracyclines, fluoroquinolones, and organochlorines predominated. For the average adult, all HQs were \u226a1 and the cumulative HI was 0.031; heptachlor and dieldrin dominated (P95 %ADI 6.2 and 4.7). The child HI (\u22480.062) remained below unity; chloramphenicol P95 MOE fell to 253. Central-tendency dietary risk is low, but high-consumer tails, cumulative exposure, prohibited-substance detection and small-study effects justify strengthened, Codex-aligned residue surveillance, withdrawal-period enforcement and risk-based national monitoring within a One-Health framework."

Growing evidence indicates that nutrition, environment, and lifestyle significantly influence disease development, progression, and treatment response. Nutrients such as vitamins, minerals, omega-3 fatty acids, and polyphenols affect neuroinflammation, oxidative stress, mitochondrial health, and neurotransmitter function. Dietary patterns like the Mediterranean and ketogenic diets offer protective benefits in clinical and experimental contexts. Meanwhile, environmental neurotoxicants-air pollution, heavy metals, pesticides, and endocrine disruptors contribute to neurodegeneration via oxidative damage, synaptic impairment, and epigenetic alterations. Lifestyle factors, such as physical activity, sleep, stress, and substance use, affect brain plasticity, neurogenesis, and metabolic health, thereby influencing disease progression over time. These factors often share common pathways such as oxidative stress, inflammation, vascular injury, mitochondrial dysfunction, and protein misfolding, underscoring the need for a comprehensive prevention and treatment strategy. Emerging therapies now incorporate personalized nutrition, lifestyle changes, and environmental risk mitigation alongside traditional drugs, supported by advances in multi-omics, digital health, and systems biology. Public health efforts to reduce neurotoxic exposure and encourage healthy habits further strengthen these approaches. This review summarizes existing mechanistic and clinical knowledge, with a focus on the potential of nutritional, environmental, and lifestyle interventions in neurological diseases. It also outlines the future research required to enhance precision neurology and strategies for brain health prevention."

Environmental risk factors, such as vitamin D deficiency and obesity, have also been implicated in multiple sclerosis pathogenesis. Statistical approaches building on these genetic data, such as Mendelian randomization and co-localization, have established putative causal links between environmental risk factors and multiple sclerosis risk, most notably for vitamin D and body mass index. However, studies have thus far revealed limited statistically significant interactions between host genetics and environmental factors beyond the major histocompatibility complex. Epigenetics (the study of non-nucleotide alterations to DNA, such as DNA methylation or histone acetylation) might provide a mechanistic framework for understanding how environmental and genetic factors interact in multiple sclerosis. Environmental factors, such as Epstein-Barr virus infection, vitamin D deficiency and smoking, are associated with epigenetic modifications at key multiple sclerosis-related genomic loci, altering the expression of multiple sclerosis risk genes in a cell type-specific manner. Transcriptomics have identified significant pathways via which genetic risk is realized, potentially providing targets for intervention. This review synthesizes current evidence on gene-environment interactions in the context of multiple sclerosis genome-wide association study findings, evaluates the strengths and limitations of various study methodologies, and discusses the challenges in elucidating the interplay between genetics and environmental factors. We propose potential strategies for future research to advance our understanding of the biological mechanisms underlying multiple sclerosis susceptibility in at-risk individuals."

The comparison tested how solvent polarity and hydrogen-bonding behavior affect product distribution under otherwise fixed conditions. FTIR, GPC, and GC-MS showed differences among the five soluble fractions. Protic solvents retained more phenolic monomers and oligomers, whereas aprotic solvents gave more oxidized products and different H:G:S profiles. The ethanol fraction had the highest apparent thermal stability (Ea\u00a0=\u00a04.14\u00a0kJ/mol; DTG peak\u00a0=\u00a0380\u00a0\u00b0C) and the lowest Mw (856\u00a0Da). Methyl cellosolve produced the highest-Mw fraction (2985\u00a0Da) and a more balanced H:G:S distribution. Guaiacol accounted for 40.6% of the ethanol fraction, coumaran for 70.4% of the THF fraction, and syringol for 17.2% of the methyl cellosolve fraction. THF-only controls did not produce a peak assigned to coumaran in the relevant retention-time window, which supports a lignin-derived origin for this signal under the tested conditions. The screening results link solvent properties to lignin fragmentation and the composition of the soluble products. Solvent recycling, residue characterization, process optimization, and atom-resolved mechanistic studies remain to be completed."

The findings were based on discussions and presentations from the Fourth International Aerosol Dosimetry Conference held in 2024 in Irvine, California. The conference used plenary sessions to promote cross-disciplinary communication and collaboration. Topics included computational models and simulations, in vitro and in vivo aerosol exposure systems, and variability in inhaled aerosol deposition. State-of-the-art research was presented, followed by open discussions to identify knowledge gaps and future priorities. Significant advances were reported in computational modeling, particularly in integrating different model types to better represent all major regions of the respiratory tract. Improvements in in vitro exposure systems enhanced particle delivery, dose measurement, and applicability to human health studies. Research also highlighted the importance of the upper airways as entry routes for inhaled medications. Dose variability emerged as a critical issue across aerosol dosimetry studies. New findings showed that inhaled ultrafine particles may acquire surface coatings after deposition and can penetrate tissues, including fetal tissues. Standardization and validation of in vitro approaches were identified as essential steps for reducing reliance on animal testing and improving human risk assessment. Internal aerosol dosimetry research continues to advance through improved models, exposure systems, and mechanistic understanding of deposited particle behavior. However, addressing dose variability, standardizing alternative testing methods, and improving data sharing remain essential for advancing risk assessment and supporting more accurate evaluations of inhaled particle effects on human health."

Although pesticides, industrial solvents, heavy metals, and air pollutants have long been implicated as potentially modifiable PD risk factors, climate change is now reshaping and amplifying these hazards through rising temperatures, worsening air quality, increased pesticide demand, extreme weather events, and wildfire-related particulate matter.This narrative review moves beyond a conventional exposure-based summary by integrating environmental toxicology, climate science, epidemiology, and mechanistic neuroscience to reframe PD risk within the context of planetary health. We summarize evidence linking major environmental hazards to PD pathogenesis, emphasizing convergent mechanisms such as oxidative stress, mitochondrial dysfunction, impaired proteostasis, neuroinflammation, blood-brain barrier disruption, and \u03b1-synuclein aggregation. We further discuss how climate-related changes may intensify these pathways and disproportionately affect vulnerable populations, including agricultural workers, older adults, socioeconomically disadvantaged communities, and individuals living in rapidly industrializing or climate-sensitive regions. Importantly, we highlight clinical and public health implications by proposing that structured environmental and occupational exposure assessment should be incorporated into PD risk evaluation, early recognition, preventive counseling, and research design. We also discuss exposure reduction, workplace protection, environmental monitoring, and regulatory policy as prevention-oriented strategies. By positioning environmental hazards and climate change as interconnected, underrecognized, and potentially modifiable contributors to PD, this review provides a framework for clinicians, researchers, and policymakers seeking to reduce the future global burden of neurodegenerative disease. Parkinson's disease (PD) is a common neurodegenerative disorder that develops over time and affects movement, balance, and many daily activities. While genes play a role, most cases of PD do not arise solely from genetics. Growing evidence shows that environmental exposures, such as pesticides, industrial chemicals, heavy metals, and air pollution, can increase the risk of developing PD. Importantly, many of these exposures can be reduced or prevented. Climate change is worsening these environmental risks. Higher temperatures, poorer air quality, increased pesticide use, and more frequent wildfires are increasing human exposure to harmful pollutants worldwide. Together, these changes may increase the number of people affected by PD, especially in communities already facing environmental or social disadvantages. This review explains how environmental toxins can damage brain cells through shared biological processes, including oxidative stress, inflammation, and abnormal protein buildup. It also highlights regions and populations that may be more vulnerable to these risks. From a healthcare perspective, understanding a person's environmental and work-related exposures can help identify those at higher risk, support earlier recognition of PD, and guide prevention advice. Overall, environmental toxins and climate change are underrecognized yet actionable determinants of PD. Increasing awareness, improving environmental protections, and integrating exposure history into clinical care are key steps toward reducing the future global burden of PD."

Glycol ethers consist in a widely used class of organic solvents leading to workers and consumers exposure via many applications. Ethylene glycol ethers are gradually being replaced by propylene glycol ethers thought to be less toxic. However, their neurotoxicity is not systematically assessed before placing them on the market. Therefore, this study investigated the potential neurotoxicity of propylene glycol butyl ether (PGBE) for which no official occupational limit has been established. To this aim, new approach methodologies have been used. Human induced pluripotent stem cells-derived BrainSpheres model was exposed to PGBE and to its assumed human main metabolite, 2-butoxypropanoic acid (2BPA). An integrative multiomic approach (transcriptomics, proteomics, metabolomics and lipidomics) was adopted to assess molecular alterations, derive benchmark concentrations and define potential mechanisms of action. PGBE was neurotoxic at occupationally relevant exposure concentrations. This was shown for the first time in human cells. Although PGBE was more cytotoxic than 2BPA, both compounds showed very similar neurotoxicity. PGBE and 2BPA strongly affected the cell cycle, induced oxidative stress and perturbed energy and lipid metabolism. They also targeted specific nervous system processes, such as axon guidance and synapse organization. Finally, 2BPA might trigger ferroptosis by increased iron uptake. Our in vitro results show an urgent need for public health authorities to carefully assess the risk glycol ethers pose to humans, to properly protect the workers as well as individuals in the general population unknowingly exposed from indoor air contaminations."

This review examines modifiable non-infectious determinants across the life course and proposes integrated prevention strategies. Key factors include vitamin D deficiency, low UV exposure, smoking, adolescent obesity, air pollution, and chemical environmental exposures. Mendelian randomization studies support the causality of several determinants, particularly low vitamin D and high BMI. Adolescence emerges as a critical susceptibility window where the maturing immune system is uniquely sensitive to metabolic and environmental triggers. Among validated interventions, vitamin D supplementation stands out for its ability to reduce disease activity in early MS. Effective prevention requires both individual actions and structural public health policies, such as air quality regulations and urban \"walkability\". Future efforts should prioritize multimodal strategies targeting high-risk youths through the educational system (physical activity, weight management, and smoking prevention). These holistic approaches offer broad-spectrum benefits, reducing the burden of MS while preventing comorbidities, including cardiovascular, metabolic but also cancer."

Here, we review current evidence for the involvement of EBV in MS, its impact on existing therapeutics, and strategies for novel therapeutic directions. Compelling evidence indicates EBV infection precedes MS onset, likely contributing to disease initiation, relapses, and possibly progression through mechanisms such as molecular mimicry, B cell immortalization, and viral reactivation. Current MS therapies may indirectly suppress EBV by depleting B cells or restricting lymphocyte CNS entry. Novel strategies, including CAR-T/-NK cells, adoptive T cells, \"kick and kill\" approaches, and vaccines, aim to directly target EBV and offer promising new avenues for MS therapy."

Epstein-Barr virus (EBV) infection has been implicated as a major environmental risk factor in MS pathogenesis. Despite the availability of disease-modifying therapies, effective targeted interventions for progressive disease remain limited. In this study, an EBV-informed integrative computational framework combining MS transcriptomic datasets, EBV-associated transcriptional signatures, GWAS susceptibility genes, and network analyses was employed to identify molecular targets associated with immune dysregulation in MS. RNA-sequencing datasets related to MS and EBV infection were obtained from the GEO database, whereas MS susceptibility genes were retrieved from the GWAS Catalog. Differential expression analysis identified 275, 200, and 773 significant DEGs in CD4\u207a T cells, CD8\u207a T cells, and CD14\u207a monocytes, respectively, along with 8,633 EBV-associated DEGs. Integrative overlap and enrichment analyses revealed convergence at the pathway level, particularly involving B-cell receptor signaling, Fc receptor activation, antigen presentation, complement activation, and inflammatory immune signaling. Hub gene analysis identified IL6, CD86, CD28, and PTPN11 as central regulatory nodes. Based on biological relevance and structural tractability, PTPN11/SHP2 was selected as the final therapeutic target. Structure-based drug repurposing identified Gusperimus as the top-ranked ligand, exhibiting a favorable docking score (-\u20099.287\u00a0kcal/mol) and a broader interaction profile within the SHP2 allosteric pocket relative to the reference inhibitor SHP099 (-\u20097.915\u00a0kcal/mol). Molecular dynamics simulations supported stable occupancy of the SHP2 allosteric pocket by Gusperimus over a 100 ns trajectory. Collectively, these findings highlight SHP2 as a potential therapeutic target and identify Gusperimus as a candidate for further investigation in MS-associated immune dysregulation."

To investigate associations between retrospective lifetime shift work exposure and MS diagnosis and between prospective shift work exposure and incident MS over 13 years of follow-up in the UK Biobank cohort. Participants that were in work and free of MS at baseline were followed up for 13 years, and lifetime exposure to night, day and mixed shift work was assessed in a subset of participants. Logistic regression and Cox proportional hazard models were applied to test associations between shift work and MS diagnosis, controlling for demographic and lifestyle confounders. Lifetime exposure to mixed, day or night shift work was not associated with an increased risk of MS diagnosis. No significant associations were observed for early-life shift work exposure or in prospective analysis of those reporting shift work at baseline. Factors such as female sex, smoking, childhood obesity and reduced sunlight exposure were consistently associated with higher MS risk. There was no evidence for an association between shift work and the risk of MS diagnosis in this cohort, in retrospective analysis of lifetime exposure or in prospective studies of shift work at baseline following 13 years of follow-up.

Environmental risk factors, such as vitamin D deficiency and obesity, have also been implicated in multiple sclerosis pathogenesis. Statistical approaches building on these genetic data, such as Mendelian randomization and co-localization, have established putative causal links between environmental risk factors and multiple sclerosis risk, most notably for vitamin D and body mass index. However, studies have thus far revealed limited statistically significant interactions between host genetics and environmental factors beyond the major histocompatibility complex. Epigenetics (the study of non-nucleotide alterations to DNA, such as DNA methylation or histone acetylation) might provide a mechanistic framework for understanding how environmental and genetic factors interact in multiple sclerosis. Environmental factors, such as Epstein-Barr virus infection, vitamin D deficiency and smoking, are associated with epigenetic modifications at key multiple sclerosis-related genomic loci, altering the expression of multiple sclerosis risk genes in a cell type-specific manner. Transcriptomics have identified significant pathways via which genetic risk is realized, potentially providing targets for intervention. This review synthesizes current evidence on gene-environment interactions in the context of multiple sclerosis genome-wide association study findings, evaluates the strengths and limitations of various study methodologies, and discusses the challenges in elucidating the interplay between genetics and environmental factors. We propose potential strategies for future research to advance our understanding of the biological mechanisms underlying multiple sclerosis susceptibility in at-risk individuals."

Cumulative lifetime exposures (i.e. the exposome) contribute to ILD onset and progression by interacting with genetic susceptibility and influencing multiple molecular pathways. This review summarizes current evidence evaluating how environmental exposures interact across the genome, epigenome, transcriptome, proteome, metabolome, and microbiome to drive ILD pathogenesis. Environmental exposures, including air pollution, influence ILD risk through interactions with genetic factors that modify disease susceptibility. Epigenetic mechanisms, particularly DNA methylation, reflect key pathways through which exposures may contribute to ILD onset and progression and serve as sensitive biomarkers of environmental injury. Exposure-associated molecular alterations can be detected across multiple omic layers, including transcriptomic, proteomic, and metabolomic profiles. In parallel, exposures like cigarette smoking, silica, and air pollution influence the respiratory microbiome, with potential downstream effects on immune responses and fibrogenesis. Integrating these findings highlights environmentally-sensitive pathways that may represent novel targets for therapeutic modulation. Integration of exposomic and multiomic molecular frameworks offers new opportunities to improve ILD risk stratification, prognostication, and precision therapeutic development, while also strengthening our mechanistic understanding of environmentally-mediated disease."

Of the 1294 participants initially recruited, 1292 with complete demographic information were included in the final analyses. Serum concentrations of 22 PFASs were measured by solid-phase extraction coupled with UPLC-MS/MS, and nine PFASs detected in more than 75% of samples were analyzed. Dietary intake frequency, sociodemographic characteristics, and lifestyle factors were collected using structured questionnaires. Multivariable linear regression and sex-stratified analyses were performed. Seafood-related food groups showed the most consistent positive associations with serum PFAS levels. Frequent consumption of shellfish, shrimp, crabs, fish, and seaweed was associated with higher concentrations of long-chain PFASs, including PFDA, PFNA, PFHxS, PFOS, and PFOA, while shrimp and crab intake was also positively associated with 6:2 Cl-PFESA. These associations were generally stronger in males, suggesting sex-related heterogeneity in the relationship between seafood intake and PFAS body burden.

The comparison tested how solvent polarity and hydrogen-bonding behavior affect product distribution under otherwise fixed conditions. FTIR, GPC, and GC-MS showed differences among the five soluble fractions. Protic solvents retained more phenolic monomers and oligomers, whereas aprotic solvents gave more oxidized products and different H:G:S profiles. The ethanol fraction had the highest apparent thermal stability (Ea\u00a0=\u00a04.14\u00a0kJ/mol; DTG peak\u00a0=\u00a0380\u00a0\u00b0C) and the lowest Mw (856\u00a0Da). Methyl cellosolve produced the highest-Mw fraction (2985\u00a0Da) and a more balanced H:G:S distribution. Guaiacol accounted for 40.6% of the ethanol fraction, coumaran for 70.4% of the THF fraction, and syringol for 17.2% of the methyl cellosolve fraction. THF-only controls did not produce a peak assigned to coumaran in the relevant retention-time window, which supports a lignin-derived origin for this signal under the tested conditions. The screening results link solvent properties to lignin fragmentation and the composition of the soluble products. Solvent recycling, residue characterization, process optimization, and atom-resolved mechanistic studies remain to be completed."

Network toxicology identified 252 shared targets between sleep-related environmental pollutants (SREPs: NO2, formaldehyde, benzene) and SD. PPI network and diagnostic model identified four hub genes (HSP90AA1, RELA, PTGS2, MMP9) with moderate-to-high predictive value (AUC: 0.708-0.979). Immune infiltration analysis showing elevated T cells and reduced astrocytes and neurons in patients with SD. Molecular simulations confirmed stable SREP-hub protein binding, with benzene exhibiting the highest affinity. Crucially, mixed SREPs exposure induced more severe toxicity than individual pollutants, demonstrating true synergistic disruption. In vivo, SREPs metabolites disrupted sleep architecture, impaired the blood-brain barrier (BBB), and induced neurobehavioral deficits. In vitro studies using brain endothelial cells (BMVECs) revealed that SREPs directly increase permeability, suppress tight junctions, and activate a pro-inflammatory cascade involving NF-\u03baB signaling, enhanced MMP9 activity, and prostaglandin E2 synthesis. Curcumin intervention effectively counteracted these effects, restoring BBB integrity, normalizing sleep patterns, and suppressing hub gene expression and neuroinflammation in vivo and in vitro by targeting the identified hub gene network.

Benth., Rutaceae), known as Wuzhuyu in Chinese and Evodiae Fructus (EF) in English, is a traditional Chinese medicine (TCM) with a history of over two thousand years. It was first documented in Shen Nong's Herbal Classic for its efficacy in dispersing cold, relieving pain, and alleviating nausea, vomiting, and diarrhea, leading to its historical use in managing gastrointestinal ailments. However, the clinical application of EF has been limited due to its associated hepatotoxicity. Existing studies have confirmed that evodiamine, rutaecarpine and other alkaloids induce hepatotoxicity via multi-pathways, but the core toxic fraction, multi-component synergistic effects and systematic toxic network of EF remain unclear. This study aims to identify the key hepatotoxic fraction of Evodiae Fructus (EF) and elucidate its underlying mechanisms. A high-throughput zebrafish model was used to screen EF extracts with different polar solvents. The hepatotoxicity of the target fraction was validated in mice. UPLC-Q-TOF-MS/MS, integrated network pharmacology, proteomic and transcriptomic analyses were performed in zebrafish and mice to screen toxic pathways, with western blot and qRT-PCR validation. High-throughput zebrafish screening of five polar extracts of EF identified the dichloromethane extract (DEEF) as the core hepatotoxic fraction. Both zebrafish and mouse models consistently indicated that DEEF induced a dose-dependent elevation of serum ALT, AST, and TBA levels, disrupted the architecture of hepatic tissue, and was accompanied by marked hepatocyte apoptosis. In mice, Masson's trichrome staining further revealed abnormal collagen deposition, along with extensive infiltration of inflammatory cells. UPLC-Q-TOF-MS/MS analysis identified 73 compounds in DEEF, with 48 alkaloids (indole and quinolone types) being the dominant components, in addition to flavonoids, limonoids, and organic acids. Integrated network pharmacology, transcriptomic and proteomic analyses revealed dose-dependent global alterations in hepatic gene and protein expression profiles. Mechanistically, DEEF upregulated bile acids (BAs) synthesis enzymes (CYP7A1, CYP27A1) and downregulated efflux transporters (BSEP, MRP2). These changes were associated with activation of PI3K-AKT/MAPK/p53/NF-\u03baB pathways and modulation of the Bax/Bcl-2/Caspase-3 apoptotic axis, as indicated by multi-omics enrichment and validated by protein and gene expression analyses. This study is the first to confirm that DEEF represents the core toxic fraction of EF and to disclose that its hepatotoxic mechanism is driven by the crosstalk between BAs metabolism disorder and multi-signaling cascade. Our findings fill the research gap between studies on crude extract and monomers, and provide a critical foundation for targeted detoxification and safe clinical application of EF."

Median THg was 403 \u03bcg/kg in hair, 1.60 \u03bcg/L in blood and 0.438 \u03bcg/L in urine. Fish showed the highest food THg, whereas work and indoor dust had the highest matrix concentrations. Hair was MeHg-dominant but contained substantial IHg, and \u0394199Hg values were positive but modest.

Therefore, continuous doping control is essential for maintaining fairness and athlete's safety. Accurate and rapid detection of prohibited substances at their lowest levels in complex biological matrices, such as blood, urine, and plasma, is crucial for reliable anti-doping analysis. This critical review focuses on the applications of mass spectrometry (MS) for the detection of doping agents across diverse biological matrices. Special emphasis is given to advanced mass spectrometry platforms, particularly LC-QQQ-MS, LC-QTOF-MS, Orbitrap-MS/MS, and IRMS which are widely used for the routine screening, confirmation, and identification of emerging doping agents. Microsampling approaches such as dried blood spots (DBS) and volumetric absorptive microsampling (VAMS) provide superior alternatives to traditional sampling. Furthermore, comprehensive understanding of sample pretreatment and analytical techniques is essential. In this regard, novel microextraction techniques, including solid-phase microextraction (SPME), liquid-phase microextraction (LPME), supramolecular solvents (SUPRAS), and deep eutectic solvents (DES), have improved multi-analyte sample pretreatment strategies and facilitated advanced automation. This review also offers valuable guidance in selecting appropriate chromatography coupled mass spectrometry\u2011based analytical methods with sensitive detection, sample pretreatment techniques, and storage conditions during sports drug testing."

Their reliable determination depends strongly on efficient sample preparation, but conventional organic solvent extraction often raises concerns related to solvent consumption, toxicity, selectivity, and sample-cleanup burden. Deep eutectic solvents (DESs) have been widely explored as tunable extraction media for phenolic compounds because their polarity, viscosity, hydrogen-bonding capacity, and solvation behavior can be adjusted by changing the hydrogen-bond acceptor, hydrogen-bond donor, molar ratio, and water content. However, conventional DES systems still face important limitations, including slow mass transfer caused by high viscosity, difficulty in solvent removal due to low volatility, incomplete analyte recovery, and possible interference with chromatographic or mass-spectrometric analysis. This review summarizes conventional DES-based extraction of phenolic compounds as the baseline, and then focuses on responsive switchable DESs (RS-DESs) as recovery-oriented solvent systems. RS-DESs can undergo reversible changes in phase behavior, polarity, miscibility, or solvation ability in response to temperature, pH, CO2/N2, or ionic strength, thereby facilitating extraction, phase separation, analyte recovery, and solvent recycling. Particular attention is paid to extraction mechanisms, structure-property relationships, quantitative comparison with conventional DES systems, and analytical compatibility with HPLC, LC-MS, and related sample-cleanup workflows. Finally, the review discusses current scientific, analytical, and industrial challenges, including switching reproducibility, phenolic stability, DES residues, matrix effects, toxicity, biodegradability, and scale-up feasibility."

Growing evidence indicates that nutrition, environment, and lifestyle significantly influence disease development, progression, and treatment response. Nutrients such as vitamins, minerals, omega-3 fatty acids, and polyphenols affect neuroinflammation, oxidative stress, mitochondrial health, and neurotransmitter function. Dietary patterns like the Mediterranean and ketogenic diets offer protective benefits in clinical and experimental contexts. Meanwhile, environmental neurotoxicants-air pollution, heavy metals, pesticides, and endocrine disruptors contribute to neurodegeneration via oxidative damage, synaptic impairment, and epigenetic alterations. Lifestyle factors, such as physical activity, sleep, stress, and substance use, affect brain plasticity, neurogenesis, and metabolic health, thereby influencing disease progression over time. These factors often share common pathways such as oxidative stress, inflammation, vascular injury, mitochondrial dysfunction, and protein misfolding, underscoring the need for a comprehensive prevention and treatment strategy. Emerging therapies now incorporate personalized nutrition, lifestyle changes, and environmental risk mitigation alongside traditional drugs, supported by advances in multi-omics, digital health, and systems biology. Public health efforts to reduce neurotoxic exposure and encourage healthy habits further strengthen these approaches. This review summarizes existing mechanistic and clinical knowledge, with a focus on the potential of nutritional, environmental, and lifestyle interventions in neurological diseases. It also outlines the future research required to enhance precision neurology and strategies for brain health prevention."

Several environmental factors have been discussed as possible causing agents, e.g. organic solvents, whose impact on the disease is analysed in this review. Systematic search strategies were used to identify high-quality studies of workers exposed to organic solvents, published up to September 30, 2019, in databases, such as PubMed, Cochrane library and Scopus. The exposure was in most studies obtained by questionnaires, supplemented with telephone interviews. The diagnosis MS was mainly detemined following a thorough neurological examination. Finally, fourteen case-control studies and two cohort studies met the inclusion criteria and were included in the meta-analysis. Random effects models were used to pool the results of the studies. The odds ratios from the 14 case-control studies included in the meta-analysis ranged from 0.12-4.0. Five case-control studies and one cohort study showed a significant association between the development of multiple sclerosis and exposure to organic solvents. The results from the other nine case-control studies and from one of the two cohort studies did not reach statistical significance. The pooled data from the 14 case-control studies gave an OR of 1.44 (95% CI 1.03-1.99), which shows a moderately increased risk of developing MS after exposure to organic solvents. The final interpretation of the result is that organic solvents may be slightly associated with an increased risk to develop MS. In addition, other factors, e.g. genetic markers and smoking, may contribute to the development of the disease."

We aimed to investigate the influence of exposure to organic solvents on MS risk, and a potential interaction between organic solvents and MS risk human leukocyte antigen (HLA) genes. Using a Swedish population-based case-control study (2,042 incident cases of MS and 2,947 controls), participants with different genotypes, smoking habits, and exposures to organic solvents were compared regarding occurrence of MS, by calculating odds ratios with 95% confidence intervals using logistic regression. A potential interaction between exposure to organic solvents and MS risk HLA genes was evaluated by calculating the attributable proportion due to interaction. Overall, exposure to organic solvents increased the risk of MS (odds ratio 1.5, 95% confidence interval 1.2-1.8, p = 0.0004). Among both ever and never smokers, an interaction between organic solvents, carriage of HLA-DRB1*15, and absence of HLA-A*02 was observed with regard to MS risk, similar to the previously reported gene-environment interaction involving the same MS risk HLA genes and smoke exposure. The mechanism linking both smoking and exposure to organic solvents to MS risk may involve lung inflammation with a proinflammatory profile. Their interaction with MS risk HLA genes argues for an action of these environmental factors on adaptive immunity, perhaps through activation of autoaggressive cells resident in the lungs subsequently attacking the CNS."

A State scheme includes a list of accepted associations between occupations and diseases with evidence of a causative association. Epidemiological evidence of a doubled risk in the occupation concerned is usually required. This takes no account of variation of exposures within occupations, excluding many occupations where risk is less than doubled. In such cases, compensation for a perceived industrial illness may be obtained in Civil Courts, where excessive exposures can be considered. To show that in the Civil Courts evidence of excessive exposure may lead to compensation for diseases which are not yet compensable as Industrial Injuries in the UK and to draw attention to the association of multiple sclerosis (MS) with solvent exposure. We report the case of an industrial spray painter, who claimed his MS had been caused by high-level exposure to organic solvents, and our examination of the epidemiological evidence submitted. The painter received compensation by an out-of-court settlement, despite the overall epidemiological risk in relation to solvent exposure having been shown to be less than doubled. The evidence hinged on individual risk in relation to high exposure, genetic susceptibility and demonstration of a plausible mechanism. High organic solvent exposure may lead to the development of MS. Those giving evidence in Court need to be able to discuss the epidemiological and toxicological issues in relation to exposure in the individual case."

More than 200 genetic variants contribute to MS risk, with the HLA-DRB115:01 haplotype providing the strongest effect within a broader network of immune-regulatory loci. Functional genomic evidence shows that these variants primarily influence antigen presentation and lymphocyte activation, creating an immune landscape that can be further shaped by external factors. This review integrates epidemiological, genomic, and mechanistic data to outline the main determinants of MS susceptibility. Epstein-Barr virus infection emerges as the dominant infectious driver, with seroconversion preceding early neuroaxonal injury and clinical onset. In contrast, cytomegalovirus infection appears protective, likely through immune imprinting that counterbalances EBV-driven B-cell and T-cell activation. Environmental factors including cigarette smoking, adolescent obesity, vitamin D deficiency, circadian disruption, and gut microbiota dysbiosis further modify susceptibility by promoting proinflammatory immune programs and reducing regulatory stability. Many of these exposures interact synergistically with HLA-DRB115:01, amplifying risk beyond additive expectations. These determinants influence shared immunological pathways regulating antigen presentation, lymphocyte differentiation, and immune tolerance. Clarifying these biological interfaces highlights actionable domains including smoking avoidance, metabolic health optimization, vitamin D sufficiency, viral prevention strategies, circadian alignment, and microbiome-targeted interventions that may inform risk-reduction and early identification efforts."

Importantly, these nongenetic factors can influence pathogenetic pathways, and some of them can be modified. Besides established MS-associated risk factors - high latitude, female sex, smoking, low vitamin D levels caused by insufficient sun exposure and/or dietary intake, and Epstein-Barr virus (EBV) infection - strong evidence now supports obesity during adolescence as a factor increasing MS risk. Organic solvents and shift work have also been reported to confer increased risk of the disease, whereas factors such as use of nicotine or alcohol, cytomegalovirus infection and a high coffee consumption are associated with a reduced risk. Certain factors - smoking, EBV infection and obesity - interact with HLA risk genes, pointing at a pathogenetic pathway involving adaptive immunity. All of the described risk factors for MS can influence adaptive and/or innate immunity, which is thought to be the main pathway modulated by MS risk alleles. Unlike genetic risk factors, many environmental and lifestyle factors can be modified, with potential for prevention, particularly for people at the greatest risk, such as relatives of individuals with MS. Here, we review recent data on environmental and lifestyle factors, with a focus on gene-environment interactions."

Environmental risk factors, such as vitamin D deficiency and obesity, have also been implicated in multiple sclerosis pathogenesis. Statistical approaches building on these genetic data, such as Mendelian randomization and co-localization, have established putative causal links between environmental risk factors and multiple sclerosis risk, most notably for vitamin D and body mass index. However, studies have thus far revealed limited statistically significant interactions between host genetics and environmental factors beyond the major histocompatibility complex. Epigenetics (the study of non-nucleotide alterations to DNA, such as DNA methylation or histone acetylation) might provide a mechanistic framework for understanding how environmental and genetic factors interact in multiple sclerosis. Environmental factors, such as Epstein-Barr virus infection, vitamin D deficiency and smoking, are associated with epigenetic modifications at key multiple sclerosis-related genomic loci, altering the expression of multiple sclerosis risk genes in a cell type-specific manner. Transcriptomics have identified significant pathways via which genetic risk is realized, potentially providing targets for intervention. This review synthesizes current evidence on gene-environment interactions in the context of multiple sclerosis genome-wide association study findings, evaluates the strengths and limitations of various study methodologies, and discusses the challenges in elucidating the interplay between genetics and environmental factors. We propose potential strategies for future research to advance our understanding of the biological mechanisms underlying multiple sclerosis susceptibility in at-risk individuals."

While the exact reasons for these increases are unknown, this trend has been attributed to increased exposure to environmental agents that are also risk factors for autoimmune disease, including xenobiotic chemicals, infections, lifestyle changes, stressful life events, and altered microbiomes, with subsequent biochemical modifications that influence immune tolerance. This review explores current understanding of mechanisms relating to environmental agents contributing to autoimmune diseases. Here we focus on the key initial mechanistic pathways that include environmentally-induced DNA damage, epigenetic alterations, protein post-translational modifications - such as hapten formation, altered autoantigen structure and cellular locations - tissue barrier disruptions, molecular mimicry, and neuroendocrine dysregulation. The processes by which these initial effects result in secondary changes to influence immunological mechanisms, which can then contribute to the development of autoimmunity and autoimmune disorders, are also discussed. While understanding of the mechanisms of environmental triggers in autoimmune diseases has expanded in recent years, and they are considered fundamental architects of autoimmune phenotypes that imprint specific molecular signatures with prognostic and therapeutic value, many important issues remain unaddressed. These include conducting longitudinal exposome studies, defining the necessary and sufficient gene-environment interactions, understanding the synergistic effects of exposure mixtures, of exposure timing and susceptibility, and impacts of chronic psychosocial stress on immune function. Addressing these knowledge gaps and advancing our understanding of the underlying causal pathways are vital for developing preventive strategies and creating safer and more effective therapies for autoimmune conditions."

Smoking is a risk factor for multiple sclerosis (MS); also, smoking has been associated with disease activity and overall prognosis for patients with MS. Cigarette smoking is an irritative agent on the lungs, in which a proinflammatory cascade starts that culminates in autoimmunity. Inflammation may increase the risk of MS in some individuals, in a process driven by antigen cross-reactivity between lung antigens and myelin antigens. Genetics plays a central role in the individual predisposition to mounting an autoimmune reaction. Also, free radicals, cyanates, and carbon monoxide in cigarette smoke may be directly toxic to neurons. Patients with MS who smoke have higher rates of disease activity, faster rates of brain atrophy, and a greater disability burden. Some of the outcomes of smoking were found to be reversible, which makes counseling key. The pathways involved in cigarette smoking should be further analyzed to understand the mechanisms whereby smoking worsens MS prognosis. The proinflammatory and neurotoxic outcomes of cigarette smoking may be shared by other environmental exposures, such as pollution and organic solvents. From a global perspective, efforts should be made to diminish the prevalence of cigarette smoking in patients with MS."

Although smoking is a well-established risk factor for RA, the role of occupational inhalants in RA development is less well recognized. This study aimed to systematically review and synthesize existing evidence on the association between occupational inhalants and the risk of developing RA. We conducted a systematic review and meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, searching MEDLINE, Embase, and Web of Science from database inception to November 20, 2024. Eligible studies were cross-sectional, were case-control and cohort designs, were population-based, reported original data on occupational inhalant exposures and RA, measured exposures, included a comparison group, and used reliable RA ascertainment methods. Studies relying solely on self-reported RA or focusing on treatment, prognosis, sick leave, or death were excluded. Two reviewers independently conducted literature screening, data extraction, and risk-of-bias assessment using the Newcastle-Ottawa Scale. Random-effects meta-analyses with relative risk were performed for cohort and case-control studies, and heterogeneity was assessed using the I2 statistic. In total, 31 studies met inclusion criteria, and 25 were included in meta-analyses across 10 types of occupational inhalants. Significant associations with RA risk were observed for exposure to silica, asbestos, solvents, pesticides, fertilizers, animal dust, and engine exhaust (relative risks ranging from 1.25 to 1.49). Moderate-to-high heterogeneity was observed in seven meta-analyses. Occupational inhalants are associated with increased RA risk, underscoring the importance of workplace prevention strategies and further research into biologic mechanisms."

This study aimed to evaluate the toxicological effects of PM2.5 associated with inflammatory factors in a mouse's multiple sclerosis (MS) model. Thirty C57BL/6 male mice were categorized into five groups: a group of healthy mice, a control cuprizone-induced MS group, and three MS-induced groups, intranasally exposed to three concentrations of ambient air PM2.5 (5, 10, and 20\u2009mg/mL) from Tehran in a phosphate-buffered saline (PBS) solution. All mice were investigated by motor function, molecular, and histopathological assays. Moreover, the chemical content of the collected PM2.5 was assessed and reported. The cumulative exposure doses were equal to 0.025, 0.05, and 0.1\u2009mg per gram of body weight of mice, which were approximately 3.52, 7.04, and 14.08 times higher than the human daily dose in Tehran. The PM2.5-exposed groups showed a high inflammatory response characterized by a significant increase in the mRNA expression of tumor necrosis alpha (TNF-\u03b1), NLRP3, and interleukin 18 (IL-18). In addition, the PM2.5-exposed groups exhibited a notably lower velocity level, total traveled distance (TD), and duration traveled in the central zone (DC) than the control group. The histopathological assays revealed significant pathological alterations and demyelination in the PM2.5-exposed groups compared to the control group. Identifying the risks and reducing the likelihood of exposure through preventive measures and regulations can result in financial savings and improve the quality of life for MS patients."

We included all clinical studies assessing the occurrence of MS at any age in association with the exposure to any environmental risk factor during childhood or adolescence. The main outcome was the occurrence of MS. The quality assessment was performed with the critical appraisal checklist for case-control studies. Pooled unadjusted effect sizes (OR) were calculated and reported with a 95% CI from random-effects meta-analysis. The review included 87 studies conducted across 20 countries. The studies analyzed diverse environmental risk factors, including infections, vaccinations, tobacco exposure, body mass index, and other pediatric exposures. EBV infection showed a significant positive association with MS risk (ES\u2009=\u20092.38, 95% CI\u2009=\u20091.80-3.15). Breastfeeding showed limited protective associations, and various adverse social experiences like bullying and sexual abuse were linked to increased MS risk. Active smoking during childhood/adolescence and obesity during these periods were associated with higher MS risk, while normal body mass index was protective. Antibiotic and chemical exposures, as well as vitamin D deficiency, were linked to higher MS risk. The review highlighted substantial heterogeneity and identified publication bias in studies on infections and vaccinations. Environmental risk factors for MS are important during childhood and adolescence. The first 20\u2009years are a key window for prevention and should be seen as an opportunity."

Similarly, epidemiological studies implicate numerous environmental risk factors in MS risk, but these cannot identify specific causal mechanisms. We review our current knowledge of genetic mechanisms in MS, including the critical role of expression quantitative trait locus (eQTL) mapping in translating genetic risk loci into causal mechanisms. Molecular and functional context has emerged as an important missing component of these studies, and we discuss how environmental risk factors can be modelled in a quantitative genetic context to identify disease mechanisms. In parallel, we highlight recent advances in which quantitative genetic methods establish a causal role for low vitamin D and obesity in MS, and to dissect the mechanisms through which these operate. As genetic, transcriptional, and epigenetic studies continue to expand, further mechanistic insights for MS are likely to come from the integration of genetic and environmental data."

Evidence regarding its association with multiple sclerosis (MS) remains conflicting, limited by small sample sizes. PubMed, Embase, Scopus, and Cochrane controlled register of trials (CENTRAL) were searched on September 9, 2025 without any language or time restrictions. The inclusion criteria were observational studies that evaluated the association between exposure to air pollutants and MS development or severity. Hazard ratios (HRs) with 95% confidence intervals (CIs) were pooled as effect estimates using the fixed or random effects model. Exposures included PM2.5, PM10, nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone (O3). Outcomes were MS risk and severity, including relapses, disability progression measured with the Expanded Disability Status Scale (EDSS), and contrast-enhancing lesions (CELs) development. Twenty-two studies comprising 16,585,206 participants were included. Long-term exposure to PM2.5 (HR\u2009=\u20091.21; 95% CI: 1.07-1.38), PM10 (HR\u2009=\u20091.20; 95% CI: 1.02-1.42), and CO (HR\u2009=\u20093.85; 95% CI: 1.34-11.08) were associated with increased MS risk.

Regarding secondary prevention, workshop participants recommended identifying biomarkers relevant from initial immune dysregulation through to initial clinical presentation, linking biomarkers to long-term MS outcomes, developing cost-effective screening tools for MS and point-of-care testing, and developing prodromal criteria for MS that could be implemented clinically. Communication and evaluation frameworks, adoption of an implementation mind-set, and engagement of public health were highlighted as key supporting elements.

This study aimed to map MS prevalence across Isfahan Province and evaluate differences by sex and urban versus rural setting, as well as to assess any association between ambient air pollution and MS prevalence. Data from 11,456 provincially registered MS patients in 28 counties in Isfahan, Iran, were examined in this cross-sectional ecological study. Official population estimates were used to calculate the county-level MS point prevalence per 100,000 population in 2023, stratified by sex. Ratios of females to males were calculated. Annual average PM\u2082.\u2085 levels for each county were obtained from state sources for the same period. MS prevalence was compared between urban and rural counties, and correlation/regression analyses were used to test associations with pollutant levels. The prevalence of MS varied widely, ranging from 322.7 in Isfahan County to 15.4 per 100,000 in rural Jarghouyeh. Although there was no significant correlation between the sex disparity and overall prevalence, females were more affected in every county (F/M ratio: 2.0-9.0). Although PM\u2082.\u2085 levels in Isfahan were extremely high (annual mean=41 \u03bcg/m\u00b3, >8 times the WHO guideline of 5 \u03bcg/m\u00b3), we found no significant correlation between ambient pollutant concentrations and MS prevalence in the province."

It is unknown if these substances can affect the course of autoimmune diseases. This study was based on 907 individuals with multiple sclerosis (MS) and 907 matched controls, where the MS cases were followed longitudinally using the Swedish MS register. We demonstrate sex- and disease-specific differences in serum PFAS concentrations between individuals with MS and controls. Moreover, two OH-PCBs (4-OH-CB187 and 3-OH-CB153) are associated with an increased risk of developing multiple sclerosis, regardless of sex and immigration status. With a clinical follow-up time of up to 18 years, an increase in serum concentrations of perfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), and perfluorodecanoic acid (PFDA) decreases the risk of confirmed disability worsening in both sexes, as well as perfluoroheptanesulfonic acid (PFHpS) and perfluorononanoic acid (PFNA), only in males with MS.

Mouse brain, liver, and kidney tissues were used to systematically compare the two matrix deposition methods of sublimation and spray coating in the FluoMALDI pipeline. Half of each tissue section was left uncoated as control by covering it during matrix application. Six MALDI matrices including 9-aminoacridine, norharmane, \u03b1-cyano-4-hydroxycinnamic acid, 2,5-dihydroxyacetophenone, 2,5-dihydroxybenzoic acid, or sinapinic acid were applied in equal amounts. Autofluorescence enhancements were evaluated using three fluorescence channels in the green, red, and far-red range of the spectrum, revealing matrix- and tissue-dependent fluorescence enhancement profiles. Norharmane matrix resulted in the most consistent tissue autofluorescence enhancements across deposition methods, with the highest enhancements in the green channel when applied by spray coating, and in the red and far-red channels when applied by sublimation coating. Matrix crystal size did not significantly impact the observed fluorescence enhancement effects for all six tested matrices. The two ionization modes of MALDI-1 and MALDI-2 imaging were also compared on brain, liver, and kidney tissue sections to assess lipid detection efficiency and spatial distribution in the FluoMALDI imaging pipeline. While the spatial distributions of phosphatidylethanolamine (PE) and phosphatidylcholine (PC) species were consistent across MALDI ionization modes and matrix deposition methods, lipid detection efficiency varied depending on the matrix type, matrix crystal size, tissue type, and MALDI ionization mode. Sublimation, which produced fine crystals without solvents, generally resulted in higher phospholipid detection efficiency than spray coating for lipids including PE(36:2) and PC(36:2) in both MALDI-1 and MALDI-2 imaging. These findings highlight that the matrix choice and matrix deposition method applied significantly affect tissue autofluorescence enhancement, spatial resolution, and lipid detection efficiency in MALDI-1 and MALDI-2 imaging modes, offering valuable insights for selecting optimal matrix deposition for FluoMALDI imaging based on a given study's research goals."

Systematic search strategies were used to identify high-quality studies of workers exposed to organic solvents, published up to September 30, 2019, in databases, such as PubMed, Cochrane library and Scopus. The exposure was in most studies obtained by questionnaires, supplemented with telephone interviews. The diagnosis MS was mainly detemined following a thorough neurological examination. Finally, fourteen case-control studies and two cohort studies met the inclusion criteria and were included in the meta-analysis. Random effects models were used to pool the results of the studies. The odds ratios from the 14 case-control studies included in the meta-analysis ranged from 0.12-4.0. Five case-control studies and one cohort study showed a significant association between the development of multiple sclerosis and exposure to organic solvents.

We aimed to investigate the influence of exposure to organic solvents on MS risk, and a potential interaction between organic solvents and MS risk human leukocyte antigen (HLA) genes. Using a Swedish population-based case-control study (2,042 incident cases of MS and 2,947 controls), participants with different genotypes, smoking habits, and exposures to organic solvents were compared regarding occurrence of MS, by calculating odds ratios with 95% confidence intervals using logistic regression. A potential interaction between exposure to organic solvents and MS risk HLA genes was evaluated by calculating the attributable proportion due to interaction. Overall, exposure to organic solvents increased the risk of MS (odds ratio 1.5, 95% confidence interval 1.2-1.8, p = 0.0004). Among both ever and never smokers, an interaction between organic solvents, carriage of HLA-DRB1*15, and absence of HLA-A*02 was observed with regard to MS risk, similar to the previously reported gene-environment interaction involving the same MS risk HLA genes and smoke exposure. The mechanism linking both smoking and exposure to organic solvents to MS risk may involve lung inflammation with a proinflammatory profile. Their interaction with MS risk HLA genes argues for an action of these environmental factors on adaptive immunity, perhaps through activation of autoaggressive cells resident in the lungs subsequently attacking the CNS."

A State scheme includes a list of accepted associations between occupations and diseases with evidence of a causative association. Epidemiological evidence of a doubled risk in the occupation concerned is usually required. This takes no account of variation of exposures within occupations, excluding many occupations where risk is less than doubled. In such cases, compensation for a perceived industrial illness may be obtained in Civil Courts, where excessive exposures can be considered. To show that in the Civil Courts evidence of excessive exposure may lead to compensation for diseases which are not yet compensable as Industrial Injuries in the UK and to draw attention to the association of multiple sclerosis (MS) with solvent exposure. We report the case of an industrial spray painter, who claimed his MS had been caused by high-level exposure to organic solvents, and our examination of the epidemiological evidence submitted. The painter received compensation by an out-of-court settlement, despite the overall epidemiological risk in relation to solvent exposure having been shown to be less than doubled. The evidence hinged on individual risk in relation to high exposure, genetic susceptibility and demonstration of a plausible mechanism. High organic solvent exposure may lead to the development of MS. Those giving evidence in Court need to be able to discuss the epidemiological and toxicological issues in relation to exposure in the individual case."

We used MR analysis to assess the associations between 65 possible risk factors and MS using data from a genome-wide association study including 14 498 cases and 24 091 controls of European ancestry. For 18 exposures not suitable for MR analysis, we conducted a systematic review to obtain the latest meta-analyses evidence on their associations with MS. Childhood and adulthood body mass index were positively associated with MS, whereas physical activity and serum 25-hydroxyvitamin D were inversely associated with MS. There was evidence of possible associations of type 2 diabetes, waist circumference, body fat percentage, age of puberty and high-density lipoprotein cholesterol. Data of systematic review showed that exposure to organic solvents, Epstein Barr virus and cytomegalovirus virus infection, and diphtheria and tetanus vaccination were associated with MS risk. This study identified several modifiable risk factors for primary prevention of MS that should inform public health policy."

More than 200 genetic variants contribute to MS risk, with the HLA-DRB115:01 haplotype providing the strongest effect within a broader network of immune-regulatory loci. Functional genomic evidence shows that these variants primarily influence antigen presentation and lymphocyte activation, creating an immune landscape that can be further shaped by external factors. This review integrates epidemiological, genomic, and mechanistic data to outline the main determinants of MS susceptibility. Epstein-Barr virus infection emerges as the dominant infectious driver, with seroconversion preceding early neuroaxonal injury and clinical onset. In contrast, cytomegalovirus infection appears protective, likely through immune imprinting that counterbalances EBV-driven B-cell and T-cell activation. Environmental factors including cigarette smoking, adolescent obesity, vitamin D deficiency, circadian disruption, and gut microbiota dysbiosis further modify susceptibility by promoting proinflammatory immune programs and reducing regulatory stability. Many of these exposures interact synergistically with HLA-DRB115:01, amplifying risk beyond additive expectations. These determinants influence shared immunological pathways regulating antigen presentation, lymphocyte differentiation, and immune tolerance. Clarifying these biological interfaces highlights actionable domains including smoking avoidance, metabolic health optimization, vitamin D sufficiency, viral prevention strategies, circadian alignment, and microbiome-targeted interventions that may inform risk-reduction and early identification efforts."

Environmental risk factors, such as vitamin D deficiency and obesity, have also been implicated in multiple sclerosis pathogenesis. Statistical approaches building on these genetic data, such as Mendelian randomization and co-localization, have established putative causal links between environmental risk factors and multiple sclerosis risk, most notably for vitamin D and body mass index. However, studies have thus far revealed limited statistically significant interactions between host genetics and environmental factors beyond the major histocompatibility complex. Epigenetics (the study of non-nucleotide alterations to DNA, such as DNA methylation or histone acetylation) might provide a mechanistic framework for understanding how environmental and genetic factors interact in multiple sclerosis. Environmental factors, such as Epstein-Barr virus infection, vitamin D deficiency and smoking, are associated with epigenetic modifications at key multiple sclerosis-related genomic loci, altering the expression of multiple sclerosis risk genes in a cell type-specific manner. Transcriptomics have identified significant pathways via which genetic risk is realized, potentially providing targets for intervention. This review synthesizes current evidence on gene-environment interactions in the context of multiple sclerosis genome-wide association study findings, evaluates the strengths and limitations of various study methodologies, and discusses the challenges in elucidating the interplay between genetics and environmental factors. We propose potential strategies for future research to advance our understanding of the biological mechanisms underlying multiple sclerosis susceptibility in at-risk individuals."

This study aimed to systematically review and synthesize existing evidence on the association between occupational inhalants and the risk of developing RA. We conducted a systematic review and meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, searching MEDLINE, Embase, and Web of Science from database inception to November 20, 2024. Eligible studies were cross-sectional, were case-control and cohort designs, were population-based, reported original data on occupational inhalant exposures and RA, measured exposures, included a comparison group, and used reliable RA ascertainment methods. Studies relying solely on self-reported RA or focusing on treatment, prognosis, sick leave, or death were excluded. Two reviewers independently conducted literature screening, data extraction, and risk-of-bias assessment using the Newcastle-Ottawa Scale. Random-effects meta-analyses with relative risk were performed for cohort and case-control studies, and heterogeneity was assessed using the I2 statistic. In total, 31 studies met inclusion criteria, and 25 were included in meta-analyses across 10 types of occupational inhalants. Significant associations with RA risk were observed for exposure to silica, asbestos, solvents, pesticides, fertilizers, animal dust, and engine exhaust (relative risks ranging from 1.25 to 1.49). Moderate-to-high heterogeneity was observed in seven meta-analyses.

Thirty C57BL/6 male mice were categorized into five groups: a group of healthy mice, a control cuprizone-induced MS group, and three MS-induced groups, intranasally exposed to three concentrations of ambient air PM2.5 (5, 10, and 20\u2009mg/mL) from Tehran in a phosphate-buffered saline (PBS) solution. All mice were investigated by motor function, molecular, and histopathological assays. Moreover, the chemical content of the collected PM2.5 was assessed and reported. The cumulative exposure doses were equal to 0.025, 0.05, and 0.1\u2009mg per gram of body weight of mice, which were approximately 3.52, 7.04, and 14.08 times higher than the human daily dose in Tehran. The PM2.5-exposed groups showed a high inflammatory response characterized by a significant increase in the mRNA expression of tumor necrosis alpha (TNF-\u03b1), NLRP3, and interleukin 18 (IL-18). In addition, the PM2.5-exposed groups exhibited a notably lower velocity level, total traveled distance (TD), and duration traveled in the central zone (DC) than the control group. The histopathological assays revealed significant pathological alterations and demyelination in the PM2.5-exposed groups compared to the control group. Identifying the risks and reducing the likelihood of exposure through preventive measures and regulations can result in financial savings and improve the quality of life for MS patients."

We included all clinical studies assessing the occurrence of MS at any age in association with the exposure to any environmental risk factor during childhood or adolescence. The main outcome was the occurrence of MS. The quality assessment was performed with the critical appraisal checklist for case-control studies. Pooled unadjusted effect sizes (OR) were calculated and reported with a 95% CI from random-effects meta-analysis. The review included 87 studies conducted across 20 countries. The studies analyzed diverse environmental risk factors, including infections, vaccinations, tobacco exposure, body mass index, and other pediatric exposures. EBV infection showed a significant positive association with MS risk (ES\u2009=\u20092.38, 95% CI\u2009=\u20091.80-3.15). Breastfeeding showed limited protective associations, and various adverse social experiences like bullying and sexual abuse were linked to increased MS risk. Active smoking during childhood/adolescence and obesity during these periods were associated with higher MS risk, while normal body mass index was protective. Antibiotic and chemical exposures, as well as vitamin D deficiency, were linked to higher MS risk. The review highlighted substantial heterogeneity and identified publication bias in studies on infections and vaccinations. Environmental risk factors for MS are important during childhood and adolescence. The first 20\u2009years are a key window for prevention and should be seen as an opportunity."

We review our current knowledge of genetic mechanisms in MS, including the critical role of expression quantitative trait locus (eQTL) mapping in translating genetic risk loci into causal mechanisms. Molecular and functional context has emerged as an important missing component of these studies, and we discuss how environmental risk factors can be modelled in a quantitative genetic context to identify disease mechanisms. In parallel, we highlight recent advances in which quantitative genetic methods establish a causal role for low vitamin D and obesity in MS, and to dissect the mechanisms through which these operate. As genetic, transcriptional, and epigenetic studies continue to expand, further mechanistic insights for MS are likely to come from the integration of genetic and environmental data."

PubMed, Embase, Scopus, and Cochrane controlled register of trials (CENTRAL) were searched on September 9, 2025 without any language or time restrictions. The inclusion criteria were observational studies that evaluated the association between exposure to air pollutants and MS development or severity. Hazard ratios (HRs) with 95% confidence intervals (CIs) were pooled as effect estimates using the fixed or random effects model. Exposures included PM2.5, PM10, nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone (O3). Outcomes were MS risk and severity, including relapses, disability progression measured with the Expanded Disability Status Scale (EDSS), and contrast-enhancing lesions (CELs) development. Twenty-two studies comprising 16,585,206 participants were included. Long-term exposure to PM2.5 (HR\u2009=\u20091.21; 95% CI: 1.07-1.38), PM10 (HR\u2009=\u20091.20; 95% CI: 1.02-1.42), and CO (HR\u2009=\u20093.85; 95% CI: 1.34-11.08) were associated with increased MS risk.

Mouse brain, liver, and kidney tissues were used to systematically compare the two matrix deposition methods of sublimation and spray coating in the FluoMALDI pipeline. Half of each tissue section was left uncoated as control by covering it during matrix application. Six MALDI matrices including 9-aminoacridine, norharmane, \u03b1-cyano-4-hydroxycinnamic acid, 2,5-dihydroxyacetophenone, 2,5-dihydroxybenzoic acid, or sinapinic acid were applied in equal amounts. Autofluorescence enhancements were evaluated using three fluorescence channels in the green, red, and far-red range of the spectrum, revealing matrix- and tissue-dependent fluorescence enhancement profiles. Norharmane matrix resulted in the most consistent tissue autofluorescence enhancements across deposition methods, with the highest enhancements in the green channel when applied by spray coating, and in the red and far-red channels when applied by sublimation coating. Matrix crystal size did not significantly impact the observed fluorescence enhancement effects for all six tested matrices. The two ionization modes of MALDI-1 and MALDI-2 imaging were also compared on brain, liver, and kidney tissue sections to assess lipid detection efficiency and spatial distribution in the FluoMALDI imaging pipeline. While the spatial distributions of phosphatidylethanolamine (PE) and phosphatidylcholine (PC) species were consistent across MALDI ionization modes and matrix deposition methods, lipid detection efficiency varied depending on the matrix type, matrix crystal size, tissue type, and MALDI ionization mode. Sublimation, which produced fine crystals without solvents, generally resulted in higher phospholipid detection efficiency than spray coating for lipids including PE(36:2) and PC(36:2) in both MALDI-1 and MALDI-2 imaging. These findings highlight that the matrix choice and matrix deposition method applied significantly affect tissue autofluorescence enhancement, spatial resolution, and lipid detection efficiency in MALDI-1 and MALDI-2 imaging modes, offering valuable insights for selecting optimal matrix deposition for FluoMALDI imaging based on a given study's research goals."

Predicting MS progression is challenging due to the disease's heterogeneity. This study aimed to apply Artificial Intelligence (AI) methods to investigate the association between the MS Severity Score (MSSS), which is a measure that integrates disability level and disease duration, and patients' longitudinal clinical data and environmental exposures. Methods We integrated long-term clinical records from the Mondino MS Center (Pavia, Italy) with environmental data, including air pollution and weather conditions, based on patients' residential locations. To address missing data, we applied a hybrid imputation strategy combining exponentially weighted moving average and linear mixed-effect models. Automated Machine Learning (AutoML) was used for feature selection. We evaluated multiple Deep Learning (DL) architectures, including recurrent neural network, long short-term memory, and Gated Recurrent Unit (GRU), using varying historical window lengths to predict the MSSS class at the next follow-up. Results The final retrospective dataset comprised 4022 visits from 535 MS patients. AutoML identified both clinical and environmental variables as important features for prediction. Models incorporating environmental data performed comparably to or better than those using only clinical variables. The GRU model achieved the most stable performance, with an average Area Under the Curve of 0.814 when environmental data were included with four prior visits. Moreover, SHAP-based feature importance ranked environmental variables like PM10, PM2.5, nitrogen dioxide, precipitation, and humidity among the top predictors. Conclusion Incorporating environmental exposures into DL models can improve MSSS prediction, highlighting the value of diverse real-world data for MS monitoring. Prediction performance across different historical window lengths was comparable, suggesting that using data from two prior follow-ups (approximately one year of monitoring) may be sufficient to provide clinically meaningful predictions of MS progression."

Importantly, these nongenetic factors can influence pathogenetic pathways, and some of them can be modified. Besides established MS-associated risk factors - high latitude, female sex, smoking, low vitamin D levels caused by insufficient sun exposure and/or dietary intake, and Epstein-Barr virus (EBV) infection - strong evidence now supports obesity during adolescence as a factor increasing MS risk. Organic solvents and shift work have also been reported to confer increased risk of the disease, whereas factors such as use of nicotine or alcohol, cytomegalovirus infection and a high coffee consumption are associated with a reduced risk. Certain factors - smoking, EBV infection and obesity - interact with HLA risk genes, pointing at a pathogenetic pathway involving adaptive immunity. All of the described risk factors for MS can influence adaptive and/or innate immunity, which is thought to be the main pathway modulated by MS risk alleles. Unlike genetic risk factors, many environmental and lifestyle factors can be modified, with potential for prevention, particularly for people at the greatest risk, such as relatives of individuals with MS. Here, we review recent data on environmental and lifestyle factors, with a focus on gene-environment interactions."

Smoking is a risk factor for multiple sclerosis (MS); also, smoking has been associated with disease activity and overall prognosis for patients with MS. Cigarette smoking is an irritative agent on the lungs, in which a proinflammatory cascade starts that culminates in autoimmunity. Inflammation may increase the risk of MS in some individuals, in a process driven by antigen cross-reactivity between lung antigens and myelin antigens. Genetics plays a central role in the individual predisposition to mounting an autoimmune reaction. Also, free radicals, cyanates, and carbon monoxide in cigarette smoke may be directly toxic to neurons. Patients with MS who smoke have higher rates of disease activity, faster rates of brain atrophy, and a greater disability burden. Some of the outcomes of smoking were found to be reversible, which makes counseling key. The pathways involved in cigarette smoking should be further analyzed to understand the mechanisms whereby smoking worsens MS prognosis. The proinflammatory and neurotoxic outcomes of cigarette smoking may be shared by other environmental exposures, such as pollution and organic solvents. From a global perspective, efforts should be made to diminish the prevalence of cigarette smoking in patients with MS."

Several radiopharmaceuticals have evolved in the last two decades. We are reporting the synthesis of the amyloid imaging PET tracer fluorine-18[18F]NAV4694 in the FX2N synthesis module under GMP-compliant conditions for clinical use. The radiosynthesis was standardised in the FX2N synthesis module, and the precursor concentration was varied from 0.5 to 2.0\u00a0mg for labelling with 18F at 110\u00a0\u00b0C, with a reaction time of 5-10\u00a0min, followed by hydrolysis with 0.6\u00a0M HCl for 5\u00a0min. The final purification was standardised with various C18 cartridges to get the maximum yield. All standard quality controls were performed, along with in vivo stability. Briefly, 350\u00a0\u00b1\u00a050 MBq of the [18F]NAV4694 was injected intravenously in patients, and PET-MR imaging was performed. The images were processed, and the distribution of the tracer was visually observed in the brain. A minimum of 2\u00a0mg concentration was found to be suitable for radiolabeling at 110\u00a0\u00b0C for 10\u00a0min and purified via C18 plus long cartridge, providing the highest radiochemical yield of 13\u00a0\u00b1\u00a03\u00a0% (decay corrected). The radiochemical purity was 99\u00a0\u00b1\u00a00.5\u00a0% with a molar activity of 255\u00a0\u00b1\u00a0125 GBq/\u03bcmol. The retention time of the [18F]NAV4694 was 17.6\u00a0\u00b1\u00a00.8\u00a0min, which was consistent with the UV/Vis peak of cold NAV4694 at 17.4\u00a0\u00b1\u00a00.7\u00a0min. The residual solvents, like DMSO and ethanol, were less than the prescribed limit. The HPLC (from plasma) showed no primary metabolites in the plasma, and the stability was 96\u00a0\u00b1\u00a02\u00a0% (in vitro) and 94\u00a0\u00b1\u00a02\u00a0% (in vivo). The human biodistribution showed a rapid clearance from the blood. The visual analysis showed uptake in cortical grey matter in a positive amyloid scan and in white matter in an amyloid-negative scan. [18F]NAV4694 was successfully synthesised in the FX2N synthesis module with high radiochemical purity. It showed distinctive uptake patterns in amyloid-positive and negative scans."

More than 200 genetic variants contribute to MS risk, with the HLA-DRB115:01 haplotype providing the strongest effect within a broader network of immune-regulatory loci. Functional genomic evidence shows that these variants primarily influence antigen presentation and lymphocyte activation, creating an immune landscape that can be further shaped by external factors.

Emerging evidence indicates the existence of a lung-brain axis, through which pulmonary pathology and environmental exposures can influence neurological health. The current review highlights the mechanistic and clinical evidence linking chronic lung inflammation, air pollution, and immune dysregulation to the onset and progression of Alzheimer's disease (AD), Parkinson's disease (PD), Multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS). A pathway-based framework is presented in which lung inflammation, systemic cytokine release, oxidative stress, blood-brain barrier disruption, immune priming, and protein misfolding mediate lung-to-brain communication. Associations between chronic obstructive pulmonary disease, asthma, particulate matter exposure, and adverse neurological outcomes including cognitive decline, brain atrophy, disease progression, and elevated neurodegenerative risk are emphasized. Specific mechanisms are addressed, including immune-mediated effects in multiple sclerosis, inhalation-driven protein aggregation in Parkinson's disease, and vascular and oxidative injury contributing to dementia and amyotrophic lateral sclerosis. COVID-19 is considered a clinical model of acute lung-brain axis disruption, demonstrating inflammation-driven neurocognitive consequences, and its role in this context was also highlighted. Additionally, potential preventive and therapeutic strategies are discussed, highlighting pulmonary health and environmental exposure reduction as modifiable factors that may help mitigate neurological disease. This integrative review underscores the clinical relevance of the lung-brain axis and calls for interdisciplinary strategies to improve neurological outcomes through pulmonary and environmental interventions."

Oxidative stress has been proposed as a key mediator linking occupational exposure to impaired sperm morphology and function. This study aimed to evaluate the association between occupational exposure to chemical solvents and toxic metals and alterations in sperm function, with particular emphasis on oxidative stress-mediated pathways. In this case-control study, semen samples were collected from teratozoospermic men occupationally exposed to chemical solvents and heavy metals (n\u2009=\u200960) and from age-matched normozoospermic controls without known occupational exposure (n\u2009=\u200930). Standard seminal parameters were assessed according to WHO guidelines. Oxidative stress status was evaluated by measuring reactive oxygen species (ROS) and malondialdehyde (MDA) levels, along with antioxidant defense markers, including superoxide dismutase (SOD), catalase, and reduced glutathione (GSH). Sperm functional integrity was assessed through acrosome integrity assays and sperm DNA fragmentation (SDF), evaluated using the comet assay and flow cytometry. Levels of toxic metals (cadmium, lead, and chromium) were quantified using atomic absorption spectrophotometry. Occupationally exposed teratozoospermic men exhibited significantly elevated oxidative stress markers, with increased ROS levels (32.0\u2009\u00b1\u20099.0 vs. 15.0\u2009\u00b1\u20095.0) and MDA concentrations (4.8\u2009\u00b1\u20091.1 vs. 2.1\u2009\u00b1\u20090.6 nmol/mL), accompanied by a marked reduction in antioxidant defense markers (SOD, catalase, and GSH; p\u2009<\u20090.05) compared with controls. The proportion of acrosome-intact spermatozoa was significantly lower in exposed men (38.3%\u2009\u00b1\u20099.2% vs. 62.4%\u2009\u00b1\u200910.1%). Both comet assay and flow cytometric analyses demonstrated significantly higher levels of sperm DNA fragmentation in the exposed group. Furthermore, quantitative analysis revealed significantly elevated body burdens of cadmium, lead, and chromium among occupationally exposed individuals. These findings indicate that oxidative stress represents a central pathophysiological mechanism linking occupational exposure to chemical solvents and heavy metals with sperm functional impairment and teratozoospermia. The results underscore the importance of routine reproductive health surveillance and oxidative stress monitoring among workers in high-risk occupational settings."

However, the traditional polymer synthesis and/or polymer-based separator modifications have mostly been carried out using harmful and expensive organic solvents. In this study, a powder-type polyimide (PI) was synthesized using water as a solvent, and then PI-particle-containing coating slurries were prepared in an aqueous dispersion medium. The coating slurries were applied on a polyethylene (PE) separator to obtain PI-particle-coated PE (PI-PE) separators. Thermal and mechanical properties were evaluated for the PI-PE separators. Electrolyte uptake, porosity, air permeability, and ionic conductivity of the separators were also evaluated. The electrochemical properties of coin cells assembled with the PI-PE separator were evaluated by charge-discharge property. Coating of PI particles improves the thermal stability and electrolyte wettability of the PE separator, and LiCoO2/PI-PE separator/Li half-cells showed battery performance similar to that of bare PE half-cells.

Articles were searched in PubMed, SciVerse ScienceDirect, and Web of Science. We included all clinical studies assessing the occurrence of MS at any age in association with the exposure to any environmental risk factor during childhood or adolescence. The main outcome was the occurrence of MS. The quality assessment was performed with the critical appraisal checklist for case-control studies. Pooled unadjusted effect sizes (OR) were calculated and reported with a 95% CI from random-effects meta-analysis. The review included 87 studies conducted across 20 countries. The studies analyzed diverse environmental risk factors, including infections, vaccinations, tobacco exposure, body mass index, and other pediatric exposures. EBV infection showed a significant positive association with MS risk (ES\u2009=\u20092.38, 95% CI\u2009=\u20091.80-3.15). Breastfeeding showed limited protective associations, and various adverse social experiences like bullying and sexual abuse were linked to increased MS risk. Active smoking during childhood/adolescence and obesity during these periods were associated with higher MS risk, while normal body mass index was protective. Antibiotic and chemical exposures, as well as vitamin D deficiency, were linked to higher MS risk. The review highlighted substantial heterogeneity and identified publication bias in studies on infections and vaccinations. Environmental risk factors for MS are important during childhood and adolescence. The first 20\u2009years are a key window for prevention and should be seen as an opportunity."

AMPA recognize post-translationally modified proteins and are cross-reactive. AMPA include anti-citrullinated protein antibodies (ACPA), anti-carbamylated protein antibodies (anti-CarP), and anti-acetylated protein antibodies (AAPA). These autoantibodies can be detected years before disease onset and are associated with disease development and progression. Moreover, AMPA have been associated with genetic and environmental risk factors in RA, including human leukocyte antigen (HLA) alleles, smoking, and microbial exposure. Consequently, AMPA have been implicated in RA pathogenesis, yet their exact role remains unclear. ACPA may exert pathogenic, pro-inflammatory effects through immune complex formation, Fc gamma receptor binding on macrophages, complement activation, and increased neutrophil extracellular trap (NET) formation. Additionally, ACPA have been linked to bone loss and pain induction in mice. However, ACPA may also have protective effects through inhibition of NET release, increased NET clearance, and Fc gamma receptor binding on macrophages. These findings indicate that AMPA may have diverse functions in RA, with both pathogenic and protective effects, whereas some ACPA may not display functional activity. Further studies on AMPA characteristics and mechanisms underlying the pathogenic and protective effects may improve the understanding of the role of AMPA in RA."

Vitamin C, due to its antioxidant and neuroprotective properties, has been hypothesized to reduce MS risk, but epidemiological evidence remains inconsistent. We conducted a prospective cohort study using UK Biobank data, including 486,908 adults aged 37-70 years free of neurological disease. Regular vitamin C supplementation was self-reported at recruitment. Incident MS cases were identified during a median follow-up of 13.5 years. Propensity score weighting was used to balance a wide range of demographic, lifestyle, and health-related confounders. Weighted Cox proportional hazards models were used to estimate hazard ratios (HRs). Effect modification by polygenic risk score (PRS) for MS was assessed, and multiple sensitivity analyses were performed. During follow-up, 452 participants were diagnosed with MS. Vitamin C supplementation was reported by 8.8% of participants (missingness = 1.5%) and was associated with a lower risk of incident MS (HR = 0.51, [95%CI: 0.32; 0.82], p = 0.004). The estimate was consistent across multiple sensitivity analyses. The association varied according to genetic susceptibility, with significant nonlinear multiplicative interaction (p = 0.004) and additive interaction (p < 0.001). Specifically, significant associations were observed only among those with average or high MS-PRS. Vitamin C supplementation was associated with a lower risk of incident MS, with the association varying across levels of genetic susceptibility. Although residual confounding cannot be excluded, sensitivity analyses did not identify similar associations for overall supplement use or multivitamin use, providing some reassurance against a generalized healthy-user effect. Replication in independent cohorts is warranted."

Herein, we report a simple and efficient nucleic acid extraction platform based on a chitosan-derived sponge-like cryogel (CSC), enabling dynamic adsorption-elution-driven separation under mild conditions. The CSC exhibits high nucleic acid binding capacity (88\u202f\u03bcg for DNA and 305\u202f\u03bcg for RNA per 10\u202fmg material) and rapid adsorption kinetics following a pseudo-second-order model. Isotherm analyses indicate that RNA and DNA binding follow the Langmuir and Freundlich models, respectively, suggesting a combined mechanism of electrostatic interaction and physical entanglement. Notably, the compressible and shape-recoverable structure enables dynamic extraction through simple aspiration-compression operations, eliminating the need for external equipment. For practical application, the CSC was integrated into a Pasteur pipette to construct a portable extraction device. This system allows rapid nucleic acid purification from Vibrio parahaemolyticus and Salmonella in bacterial cultures and milk samples, with direct compatibility for quantitative polymerase chain reaction (qPCR) and recombinase polymerase amplification (RPA)-clustered regularly interspaced short palindromic repeats (CRISPR)/Cas12a assay. The method achieved sensitive detection down to 103\u202fCFU\u202f\u00b7mL-1, outperforming a commercial kit. Importantly, the entire extraction process avoids chaotropic salts, organic solvents, and complex instrumentation, offering a simplified and environmentally friendly alternative. This work provides a practical and scalable strategy for nucleic acid purification with potential applications in point-of-care testing for food safety."

Various biogenic carboxylic acids were evaluated as catalysts, among which nicotinic acid exhibited superior catalytic efficiency, reusability, and compatibility with both aqueous and green organic solvents under conventional heating, affording the targeted products in excellent isolated yields (74-95%). The antimicrobial potential of the synthesized compounds was assessed using agar well diffusion and cup-plate methods against selected bacterial and fungal strains, revealing that several derivatives displayed significant inhibitory activity comparable to that of standard drugs.

It is particularly significant in the pharmaceutical field as a key structural unit in many drugs, such as afatinib (an anticancer drug), teriflunomide (used for multiple sclerosis treatment), acebutolol (used for hypertension and arrhythmia treatment), and paracetamol (an antipyretic and analgesic agent). However, chemical synthesis methods usually require harsh reaction conditions (e.g., high temperature, high pressure, or strongly acidic or alkaline environments) and are often accompanied by high energy consumption and environmental pollution issues. In contrast, enzymatic synthesis of amides has attracted widespread attention due to its mild conditions and environmental friendliness. To mine ancestral lipases with high activity and stability and investigate their enzymatic properties, thus achieving efficient enzymatic synthesis of amide bond-containing compounds. Ancestral lipases were screened based on a gene mining strategy employing ancestral sequence reconstruction (ASR), followed by characterization of their enzymatic properties and construction of an enzymatic reaction system for synthesis of the amide bond. Ancestral enzymes ASR-1 and ASR-7 with higher thermal stability were obtained. Substrate spectrum characterization revealed that ASR-1 preferentially catalyzed the synthesis of aromatic amides, while ASR-6 favored the synthesis of aliphatic amides. ASR-1 was purified via nickel-affinity chromatography and characterized for its enzymatic properties, showing an optimal reaction pH in Tris-HCl 7.5 and an optimal reaction temperature of 40 \u00b0C. The reaction conditions for amide synthesis were systematically optimized as 10 mg/mL wet cells, water content \u226410% (V/V), n-dodecane as solvent, 20 mmol/L amine substrate, and 10 mmol/L acyl donor. In addition, the enzyme exhibited good tolerance to nonpolar solvents, achieving an amide yield of 73.25%. This study provides a novel strategy for developing efficient and stable enzymatic processes for amide synthesis, demonstrating the promising application potential of ancestral lipases in green biomanufacturing. \u9170\u80fa\u952e\u5728\u86cb\u767d\u8d28\u3001\u836f\u7269\u3001\u519c\u7528\u5316\u5b66\u54c1\u7684\u5408\u6210\u4e2d\u8d77\u7740\u81f3\u5173\u91cd\u8981\u7684\u4f5c\u7528\uff0c\u5c24\u5176\u5728\u5236\u836f\u9886\u57df\u5177\u6709\u91cd\u8981\u610f\u4e49\uff0c\u662f\u8bb8\u591a\u836f\u7269\u7684\u5173\u952e\u780c\u5757\u5355\u5143\uff0c\u5982\u963f\u6cd5\u66ff\u5c3c(\u6297\u764c\u836f\u7269)\u3001\u7279\u7acb\u6c1f\u7c73\u7279(\u7528\u4e8e\u591a\u53d1\u6027\u786c\u5316\u75c7\u6cbb\u7597)\u3001\u4e59\u9170\u5e03\u6d1b\u5c14(\u7528\u4e8e\u9ad8\u6e17\u548c\u5fc3\u5f8b\u5931\u5e38\u6cbb\u7597)\u548c\u6251\u70ed\u606f\u75db(\u89e3\u70ed\u9547\u75db\u5242)\u3002\u7136\u800c\uff0c\u4f20\u7edf\u7684\u5316\u5b66\u5408\u6210\u65b9\u6cd5\u901a\u5e38\u9700\u8981\u4e25\u82db\u7684\u53cd\u5e94\u6761\u4ef6(\u5982\u9ad8\u6e29\u3001\u9ad8\u538b\u6216\u5f3a\u9178\u5f3a\u78b1\u73af\u5883)\uff0c\u5e76\u4f34\u968f\u8f83\u9ad8\u7684\u80fd\u6e90\u6d88\u8017\u548c\u73af\u5883\u6c61\u67d3\u95ee\u9898\u3002\u76f8\u6bd4\u4e4b\u4e0b\uff0c\u9176\u6cd5\u5408\u6210\u9170\u80fa\u5177\u6709\u6761\u4ef6\u6e29\u548c\u3001\u73af\u5883\u53cb\u597d\u7b49\u4f18\u52bf\uff0c\u53d7\u5230\u5e7f\u6cdb\u5173\u6ce8\u3002\u672c\u7814\u7a76\u65e8\u5728\u6316\u6398\u9ad8\u6d3b\u6027\u548c\u7a33\u5b9a\u6027\u7684\u7956\u5148\u8102\u80aa\u9176\uff0c\u5e76\u63a2\u7a76\u5176\u9176\u5b66\u6027\u8d28\uff0c\u5b9e\u73b0\u9170\u80fa\u952e\u5316\u5408\u7269\u7684\u9ad8\u6548\u9176\u6cd5\u5408\u6210\u3002\u57fa\u4e8e\u7956\u5148\u5e8f\u5217\u91cd\u5efa(ancestral sequence reconstruction, ASR)\u7684\u57fa\u56e0\u6316\u6398\u7b56\u7565\u7b5b\u9009\u7956\u5148\u8102\u80aa\u9176\uff0c\u5e76\u5bf9\u5176\u8fdb\u884c\u4e86\u9176\u5b66\u6027\u8d28\u8868\u5f81\uff0c\u6784\u5efa\u9176\u4fc3\u9170\u80fa\u952e\u5408\u6210\u53cd\u5e94\u4f53\u7cfb\u3002\u901a\u8fc7\u7956\u5148\u5e8f\u5217\u91cd\u5efa\u83b7\u5f97\u4e86\u5177\u6709\u66f4\u9ad8\u70ed\u7a33\u5b9a\u6027\u7684\u7956\u5148\u9176ASR-1\u548cASR-7;\u901a\u8fc7\u5e95\u7269\u8c31\u8868\u5f81\u53d1\u73b0ASR-1\u504f\u597d\u50ac\u5316\u5408\u6210\u82b3\u9999\u9170\u80fa\uff0cASR-6\u504f\u597d\u8102\u80aa\u9170\u80fa\u7684\u5408\u6210\u3002\u5bf9ASR-1\u8fdb\u884c\u4e86\u954d\u67f1\u7eaf\u5316\u548c\u9176\u5b66\u6027\u8d28\u8868\u5f81\uff0c\u53d1\u73b0\u5176\u6700\u9002\u53cd\u5e94pH\u503c\u4e3a7.5\uff0c\u4f7f\u7528Tris-HCl\u7f13\u51b2\u4f53\u7cfb\uff0c\u6700\u9002\u53cd\u5e94\u6e29\u5ea6\u4e3a40 \u2103\u3002\u8fdb\u4e00\u6b65\u7cfb\u7edf\u4f18\u5316\u4e86\u53cd\u5e94\u6761\u4ef6\u5bf9\u9170\u80fa\u5408\u6210\u7684\u5f71\u54cd\uff0c\u6700\u4f73\u53cd\u5e94\u6761\u4ef6\u4e3a10 mg/mL\u6e7f\u7ec6\u80de\u3001\u542b\u6c34\u91cf\u226410% (\u4f53\u79ef\u5206\u6570)\u3001\u6b63\u5341\u4e8c\u70f7\u4e3a\u6eb6\u5242\u3001\u5e95\u7269\u80fa\u4e3a20 mmol/L\u3001\u9170\u57fa\u4f9b\u4f53\u4e3a10 mmol/L\uff0c\u9170\u80fa\u7684\u6536\u7387\u4e3a73.25%\u3002\u672c\u7814\u7a76\u4e3a\u5f00\u53d1\u9ad8\u6548\u3001\u7a33\u5b9a\u7684\u9170\u80fa\u9176\u6cd5\u5408\u6210\u5de5\u827a\u63d0\u4f9b\u4e86\u65b0\u7b56\u7565\uff0c\u5c55\u73b0\u4e86\u7956\u5148\u8102\u80aa\u9176\u5728\u7eff\u8272\u751f\u7269\u5236\u9020\u4e2d\u7684\u826f\u597d\u5e94\u7528\u524d\u666f\u3002."

Using the PubMed database in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, relevant studies addressing genetic and/or environmental determinants of sCS in paediatric patients were systematically reviewed. A total of 1238 records were identified, of which 97 studies met inclusion criteria after full-text review. Overall, 25,877 patients were included, with 11,086 diagnosed with sCS (42.8%). Germline genetic variants potentially associated with craniosynostosis were reported in 251 patients, accounting for 12.6% of genetically tested individuals with sCS. Identified variants were distributed across 125 genes, with recurrent findings in 25 genes. Environmental and perinatal factors were more consistently reported across large population-based and case-control studies. Frequently associated factors included male sex, advanced maternal age, maternal smoking, thyroid dysfunction, fertility treatments, foetal constraint, prematurity, and abnormal birth weight, although effect sizes varied across studies. Identifiable germline genetic causes appear to account for only a minority of sCS cases, whereas epidemiological evidence suggests that environmental and perinatal influences may also contribute to disease pathogenesis. Nevertheless, most cases lack identifiable germline mutations in key signalling pathways, and the available evidence does not support either genetic or environmental factors as individually deterministic drivers of disease development. Overall, the evidence synthesized in this review supports a multifactorial model for sCS, in which rare genetic susceptibility and non-genetic influences likely interact in the etiopathogenesis of the condition rather than reflecting a single dominant aetiology. However, heterogeneity across studies, differences in genetic testing methodologies, potential bias in exposure assessment, and the limited availability of integrative analyses restrict definitive conclusions regarding the relative contribution of these factors."

The excessive swelling of flexible polymer networks, such as Nafion, often results in massive reactant crossover and diminished product yields. In this study, we report a swelling-resistant membrane engineered from functionalized 1T' phase molybdenum disulfide (MoS2). By covalently grafting acetamide groups onto the electron-rich 1T'-MoS2, we create rigid nanochannels that physically exclude organic solvents while enabling efficient proton transport. This precise molecular sieving reduces organic permeability by an order of magnitude versus commercial Nafion 117, enabling near-quantitative yields (>96%) in diverse organic electrosynthesis reactions. Bridging the gap between lab and industrial application, we demonstrate scalable fabrication of this material via slot-die coating, with the resulting large-area membranes delivering robust stability and high productivity in a scaled-up electrolyzer stack. These findings establish functionalized 2D channels as a general platform for designing next-generation ion-conductive membranes capable of operating in aggressive organic media."

Lignin is an abundant renewable biopolymer with intrinsic antimicrobial activity, but its limited aqueous processability and modest antibacterial efficacy restrict its direct application. Lignin-ferric nanoparticles (LS-Fe) were prepared through an aqueous one-pot process using sodium lignosulfonate (SLS) as the lignin precursor and Fe3\u207a as the coordination component, without the use of organic solvents. The nanoparticles were characterized for size, dispersity, surface charge, morphology, Fe incorporation, and batch-to-batch reproducibility. Their antibacterial activity against Staphylococcus aureus and Escherichia coli, effects on bacterial growth, biofilm biomass, membrane integrity, intracellular reactive oxygen species (ROS), and lipid peroxidation were evaluated. Fe/ROS-modulation experiments were performed using deferoxamine, thiourea, catalase, and H2O2. Exploratory in vivo efficacy and safety were assessed in a small mouse model of S. aureus-infected wounds. LS-Fe formed stable colloidal nanoparticles with a hydrodynamic diameter of 126.63 nm, a polydispersity index of 0.19, and a zeta potential of -44.7 mV. In preliminary in vitro assays, LS-Fe showed a descriptive trend toward greater antibacterial activity than pristine SLS against both bacterial strains.

More than 200 genetic variants contribute to MS risk, with the HLA-DRB115:01 haplotype providing the strongest effect within a broader network of immune-regulatory loci. Functional genomic evidence shows that these variants primarily influence antigen presentation and lymphocyte activation, creating an immune landscape that can be further shaped by external factors. This review integrates epidemiological, genomic, and mechanistic data to outline the main determinants of MS susceptibility. Epstein-Barr virus infection emerges as the dominant infectious driver, with seroconversion preceding early neuroaxonal injury and clinical onset. In contrast, cytomegalovirus infection appears protective, likely through immune imprinting that counterbalances EBV-driven B-cell and T-cell activation. Environmental factors including cigarette smoking, adolescent obesity, vitamin D deficiency, circadian disruption, and gut microbiota dysbiosis further modify susceptibility by promoting proinflammatory immune programs and reducing regulatory stability. Many of these exposures interact synergistically with HLA-DRB115:01, amplifying risk beyond additive expectations. These determinants influence shared immunological pathways regulating antigen presentation, lymphocyte differentiation, and immune tolerance. Clarifying these biological interfaces highlights actionable domains including smoking avoidance, metabolic health optimization, vitamin D sufficiency, viral prevention strategies, circadian alignment, and microbiome-targeted interventions that may inform risk-reduction and early identification efforts."

Emerging evidence indicates the existence of a lung-brain axis, through which pulmonary pathology and environmental exposures can influence neurological health. The current review highlights the mechanistic and clinical evidence linking chronic lung inflammation, air pollution, and immune dysregulation to the onset and progression of Alzheimer's disease (AD), Parkinson's disease (PD), Multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS). A pathway-based framework is presented in which lung inflammation, systemic cytokine release, oxidative stress, blood-brain barrier disruption, immune priming, and protein misfolding mediate lung-to-brain communication. Associations between chronic obstructive pulmonary disease, asthma, particulate matter exposure, and adverse neurological outcomes including cognitive decline, brain atrophy, disease progression, and elevated neurodegenerative risk are emphasized. Specific mechanisms are addressed, including immune-mediated effects in multiple sclerosis, inhalation-driven protein aggregation in Parkinson's disease, and vascular and oxidative injury contributing to dementia and amyotrophic lateral sclerosis. COVID-19 is considered a clinical model of acute lung-brain axis disruption, demonstrating inflammation-driven neurocognitive consequences, and its role in this context was also highlighted. Additionally, potential preventive and therapeutic strategies are discussed, highlighting pulmonary health and environmental exposure reduction as modifiable factors that may help mitigate neurological disease. This integrative review underscores the clinical relevance of the lung-brain axis and calls for interdisciplinary strategies to improve neurological outcomes through pulmonary and environmental interventions."

Oxidative stress has been proposed as a key mediator linking occupational exposure to impaired sperm morphology and function. This study aimed to evaluate the association between occupational exposure to chemical solvents and toxic metals and alterations in sperm function, with particular emphasis on oxidative stress-mediated pathways. In this case-control study, semen samples were collected from teratozoospermic men occupationally exposed to chemical solvents and heavy metals (n\u2009=\u200960) and from age-matched normozoospermic controls without known occupational exposure (n\u2009=\u200930). Standard seminal parameters were assessed according to WHO guidelines. Oxidative stress status was evaluated by measuring reactive oxygen species (ROS) and malondialdehyde (MDA) levels, along with antioxidant defense markers, including superoxide dismutase (SOD), catalase, and reduced glutathione (GSH). Sperm functional integrity was assessed through acrosome integrity assays and sperm DNA fragmentation (SDF), evaluated using the comet assay and flow cytometry. Levels of toxic metals (cadmium, lead, and chromium) were quantified using atomic absorption spectrophotometry. Occupationally exposed teratozoospermic men exhibited significantly elevated oxidative stress markers, with increased ROS levels (32.0\u2009\u00b1\u20099.0 vs. 15.0\u2009\u00b1\u20095.0) and MDA concentrations (4.8\u2009\u00b1\u20091.1 vs. 2.1\u2009\u00b1\u20090.6 nmol/mL), accompanied by a marked reduction in antioxidant defense markers (SOD, catalase, and GSH; p\u2009<\u20090.05) compared with controls. The proportion of acrosome-intact spermatozoa was significantly lower in exposed men (38.3%\u2009\u00b1\u20099.2% vs. 62.4%\u2009\u00b1\u200910.1%). Both comet assay and flow cytometric analyses demonstrated significantly higher levels of sperm DNA fragmentation in the exposed group. Furthermore, quantitative analysis revealed significantly elevated body burdens of cadmium, lead, and chromium among occupationally exposed individuals. These findings indicate that oxidative stress represents a central pathophysiological mechanism linking occupational exposure to chemical solvents and heavy metals with sperm functional impairment and teratozoospermia. The results underscore the importance of routine reproductive health surveillance and oxidative stress monitoring among workers in high-risk occupational settings."

Lignin is an abundant renewable biopolymer with intrinsic antimicrobial activity, but its limited aqueous processability and modest antibacterial efficacy restrict its direct application. Lignin-ferric nanoparticles (LS-Fe) were prepared through an aqueous one-pot process using sodium lignosulfonate (SLS) as the lignin precursor and Fe3\u207a as the coordination component, without the use of organic solvents. The nanoparticles were characterized for size, dispersity, surface charge, morphology, Fe incorporation, and batch-to-batch reproducibility. Their antibacterial activity against Staphylococcus aureus and Escherichia coli, effects on bacterial growth, biofilm biomass, membrane integrity, intracellular reactive oxygen species (ROS), and lipid peroxidation were evaluated. Fe/ROS-modulation experiments were performed using deferoxamine, thiourea, catalase, and H2O2. Exploratory in vivo efficacy and safety were assessed in a small mouse model of S. aureus-infected wounds. LS-Fe formed stable colloidal nanoparticles with a hydrodynamic diameter of 126.63 nm, a polydispersity index of 0.19, and a zeta potential of -44.7 mV. In preliminary in vitro assays, LS-Fe showed a descriptive trend toward greater antibacterial activity than pristine SLS against both bacterial strains. LS-Fe treatment was associated with increased intracellular ROS and lipid peroxidation, bacterial membrane damage, inhibition of biofilm formation, and reduced residual biomass of preformed biofilms. The attenuation of LS-Fe-mediated antibacterial activity by deferoxamine, thiourea, and catalase, together with its enhancement by exogenous H2O2, supported a possible Fe-mediated oxidative antibacterial contribution. In the exploratory infected-wound model, topical LS-Fe treatment was associated with faster wound closure, reduced bacterial burden, and improved histological features of wound repair, while no obvious histopathological abnormalities were observed in major organs at the tested dose. Aqueous one-pot preparation of LS-Fe provides a simple organic-solvent-free strategy for integrating lignin nanoparticle formation with ferric functionalization. The preliminary findings support further investigation of LS-Fe as a sustainable antibacterial nanomaterial for infected-wound management, while larger confirmatory studies and more comprehensive mechanistic and safety evaluations remain necessary."

AMPA recognize post-translationally modified proteins and are cross-reactive. AMPA include anti-citrullinated protein antibodies (ACPA), anti-carbamylated protein antibodies (anti-CarP), and anti-acetylated protein antibodies (AAPA). These autoantibodies can be detected years before disease onset and are associated with disease development and progression. Moreover, AMPA have been associated with genetic and environmental risk factors in RA, including human leukocyte antigen (HLA) alleles, smoking, and microbial exposure. Consequently, AMPA have been implicated in RA pathogenesis, yet their exact role remains unclear. ACPA may exert pathogenic, pro-inflammatory effects through immune complex formation, Fc gamma receptor binding on macrophages, complement activation, and increased neutrophil extracellular trap (NET) formation. Additionally, ACPA have been linked to bone loss and pain induction in mice. However, ACPA may also have protective effects through inhibition of NET release, increased NET clearance, and Fc gamma receptor binding on macrophages. These findings indicate that AMPA may have diverse functions in RA, with both pathogenic and protective effects, whereas some ACPA may not display functional activity. Further studies on AMPA characteristics and mechanisms underlying the pathogenic and protective effects may improve the understanding of the role of AMPA in RA."

We included all clinical studies assessing the occurrence of MS at any age in association with the exposure to any environmental risk factor during childhood or adolescence. The main outcome was the occurrence of MS. The quality assessment was performed with the critical appraisal checklist for case-control studies. Pooled unadjusted effect sizes (OR) were calculated and reported with a 95% CI from random-effects meta-analysis. The review included 87 studies conducted across 20 countries. The studies analyzed diverse environmental risk factors, including infections, vaccinations, tobacco exposure, body mass index, and other pediatric exposures. EBV infection showed a significant positive association with MS risk (ES\u2009=\u20092.38, 95% CI\u2009=\u20091.80-3.15). Breastfeeding showed limited protective associations, and various adverse social experiences like bullying and sexual abuse were linked to increased MS risk. Active smoking during childhood/adolescence and obesity during these periods were associated with higher MS risk, while normal body mass index was protective. Antibiotic and chemical exposures, as well as vitamin D deficiency, were linked to higher MS risk. The review highlighted substantial heterogeneity and identified publication bias in studies on infections and vaccinations.

Herein, we report a simple and efficient nucleic acid extraction platform based on a chitosan-derived sponge-like cryogel (CSC), enabling dynamic adsorption-elution-driven separation under mild conditions. The CSC exhibits high nucleic acid binding capacity (88\u202f\u03bcg for DNA and 305\u202f\u03bcg for RNA per 10\u202fmg material) and rapid adsorption kinetics following a pseudo-second-order model. Isotherm analyses indicate that RNA and DNA binding follow the Langmuir and Freundlich models, respectively, suggesting a combined mechanism of electrostatic interaction and physical entanglement. Notably, the compressible and shape-recoverable structure enables dynamic extraction through simple aspiration-compression operations, eliminating the need for external equipment. For practical application, the CSC was integrated into a Pasteur pipette to construct a portable extraction device. This system allows rapid nucleic acid purification from Vibrio parahaemolyticus and Salmonella in bacterial cultures and milk samples, with direct compatibility for quantitative polymerase chain reaction (qPCR) and recombinase polymerase amplification (RPA)-clustered regularly interspaced short palindromic repeats (CRISPR)/Cas12a assay. The method achieved sensitive detection down to 103\u202fCFU\u202f\u00b7mL-1, outperforming a commercial kit. Importantly, the entire extraction process avoids chaotropic salts, organic solvents, and complex instrumentation, offering a simplified and environmentally friendly alternative. This work provides a practical and scalable strategy for nucleic acid purification with potential applications in point-of-care testing for food safety."

It is particularly significant in the pharmaceutical field as a key structural unit in many drugs, such as afatinib (an anticancer drug), teriflunomide (used for multiple sclerosis treatment), acebutolol (used for hypertension and arrhythmia treatment), and paracetamol (an antipyretic and analgesic agent). However, chemical synthesis methods usually require harsh reaction conditions (e.g., high temperature, high pressure, or strongly acidic or alkaline environments) and are often accompanied by high energy consumption and environmental pollution issues. In contrast, enzymatic synthesis of amides has attracted widespread attention due to its mild conditions and environmental friendliness. To mine ancestral lipases with high activity and stability and investigate their enzymatic properties, thus achieving efficient enzymatic synthesis of amide bond-containing compounds. Ancestral lipases were screened based on a gene mining strategy employing ancestral sequence reconstruction (ASR), followed by characterization of their enzymatic properties and construction of an enzymatic reaction system for synthesis of the amide bond. Ancestral enzymes ASR-1 and ASR-7 with higher thermal stability were obtained. Substrate spectrum characterization revealed that ASR-1 preferentially catalyzed the synthesis of aromatic amides, while ASR-6 favored the synthesis of aliphatic amides. ASR-1 was purified via nickel-affinity chromatography and characterized for its enzymatic properties, showing an optimal reaction pH in Tris-HCl 7.5 and an optimal reaction temperature of 40 \u00b0C.

Its pathogenesis is driven by complex interactions between genetic susceptibility and environmental exposures. Investigating gene-environment (G\u2009\u00d7\u2009E) interactions holds significant potential to elucidate the regulatory genetic architecture underlying individual responses to environmental risk factors in childhood asthma. In this review, we systematically summarize the environmental exposure factors during prenatal and postnatal periods and analyze their independent effects on the risk of childhood asthma. Secondly, we explore the role of G\u2009\u00d7\u2009E interactions\u00a0in asthma from three perspectives: statistical interaction, mechanistic interaction, and epigenetic-mediated interaction. Finally, we evaluate current treatment and intervention strategies, distinguish established recommendations for the general population from emerging and exploratory methods, and point out existing limitations. Our analysis reinforces that investigating G\u2009\u00d7\u2009E interactions is a robust approach for uncovering the molecular mechanisms underlying childhood asthma. Despite substantial technical challenges and unresolved questions regarding generalizability and heterogeneity, such investigative strategies are expected to enhance our understanding of asthma endotypes and the development of more effective, precision-based preventive and therapeutic interventions."

The excessive swelling of flexible polymer networks, such as Nafion, often results in massive reactant crossover and diminished product yields. In this study, we report a swelling-resistant membrane engineered from functionalized 1T' phase molybdenum disulfide (MoS2). By covalently grafting acetamide groups onto the electron-rich 1T'-MoS2, we create rigid nanochannels that physically exclude organic solvents while enabling efficient proton transport. This precise molecular sieving reduces organic permeability by an order of magnitude versus commercial Nafion 117, enabling near-quantitative yields (>96%) in diverse organic electrosynthesis reactions. Bridging the gap between lab and industrial application, we demonstrate scalable fabrication of this material via slot-die coating, with the resulting large-area membranes delivering robust stability and high productivity in a scaled-up electrolyzer stack. These findings establish functionalized 2D channels as a general platform for designing next-generation ion-conductive membranes capable of operating in aggressive organic media."

However, the traditional polymer synthesis and/or polymer-based separator modifications have mostly been carried out using harmful and expensive organic solvents. In this study, a powder-type polyimide (PI) was synthesized using water as a solvent, and then PI-particle-containing coating slurries were prepared in an aqueous dispersion medium. The coating slurries were applied on a polyethylene (PE) separator to obtain PI-particle-coated PE (PI-PE) separators. Thermal and mechanical properties were evaluated for the PI-PE separators. Electrolyte uptake, porosity, air permeability, and ionic conductivity of the separators were also evaluated. The electrochemical properties of coin cells assembled with the PI-PE separator were evaluated by charge-discharge property. Coating of PI particles improves the thermal stability and electrolyte wettability of the PE separator, and LiCoO2/PI-PE separator/Li half-cells showed battery performance similar to that of bare PE half-cells. This work offers insights into the simple, eco-friendly preparation of a separator with excellent thermal stability, electrolyte wettability and effective ionic conductivity."

This study aimed to clone and express the catalase gene from Kocuria rhizophila ATCC 9341 into Escherichia coli BL21 (DE3), then characterize the purified enzyme and evaluate its potential for hydrogen peroxide degradation in textile wastewater. The 1524\u00a0bp gene was amplified and ligated into pET-21a(\u2009+) using the T4 DNA ligase enzyme. The expression of the recombinant catalase gene in E. coli BL21(DE3) was verified by using Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis, with an estimated molecular weight of 57\u00a0kDa. The purified enzyme demonstrated a specific activity of 109.55\u00a0U/mg, optimal activity at pH 7-7.5, and 50\u00a0\u00b0C. The enzyme showed significant stability up to 80\u00a0\u00b0C and in a wide range of pH (4.0-9.0) by retaining up to 70% activity. The enzyme was also found to be resistant to several organic solvents, EDTA, \u03b2-mercaptoethanol, and metal ions, but was inhibited by Cu2+ and Cr2+. In-silico studies, including 3D modeling, quality validation, and molecular docking with hydrogen peroxide, confirmed strong ligand interactions, aligning with the experimental data.

The enzymatic activity of bacteria that thrive in low-temperature environments has attracted the attention of researchers. In this study, an extracellular cold-active protease produced by Flavobacterium azizsancarii (F. azizsancarii), a novel Antarctic isolate, was partially purified by ammonium sulfate precipitation and dialysis.

Using the PubMed database in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, relevant studies addressing genetic and/or environmental determinants of sCS in paediatric patients were systematically reviewed. A total of 1238 records were identified, of which 97 studies met inclusion criteria after full-text review. Overall, 25,877 patients were included, with 11,086 diagnosed with sCS (42.8%). Germline genetic variants potentially associated with craniosynostosis were reported in 251 patients, accounting for 12.6% of genetically tested individuals with sCS. Identified variants were distributed across 125 genes, with recurrent findings in 25 genes. Environmental and perinatal factors were more consistently reported across large population-based and case-control studies. Frequently associated factors included male sex, advanced maternal age, maternal smoking, thyroid dysfunction, fertility treatments, foetal constraint, prematurity, and abnormal birth weight, although effect sizes varied across studies. Identifiable germline genetic causes appear to account for only a minority of sCS cases, whereas epidemiological evidence suggests that environmental and perinatal influences may also contribute to disease pathogenesis. Nevertheless, most cases lack identifiable germline mutations in key signalling pathways, and the available evidence does not support either genetic or environmental factors as individually deterministic drivers of disease development. Overall, the evidence synthesized in this review supports a multifactorial model for sCS, in which rare genetic susceptibility and non-genetic influences likely interact in the etiopathogenesis of the condition rather than reflecting a single dominant aetiology. However, heterogeneity across studies, differences in genetic testing methodologies, potential bias in exposure assessment, and the limited availability of integrative analyses restrict definitive conclusions regarding the relative contribution of these factors."

In a rapidly advancing field in which diverse multinational cohorts and molecular methods have been created, highly resolved microbial traits such as protein function and strain genetics can now be investigated through meta-analysis. We integrated 2371 stool metagenomes from 542 individuals with IBD and their referent counterparts from the United States, Canada, and Europe, using all 7 IBD cohorts in the Human Microbiome Bioactives Resource, which we interrogated using taxonomic, functional, and strain profiling. We systematically identified the mass expansion of proinflammatory, oral-predominant taxa in the IBD gut, such as Veillonella and Streptococcus spp. We also accurately discriminate CD from UC, a clinically challenging problem, using highly resolved microbial strain genetics (area under the curve = 0.69). Further, we observed disease-specific shifts in carbohydrate metabolism, a likely consequence of small bowel dysfunction in CD, but not UC, as well as perturbations in mucin use, increased microbial virulence and invasion cassettes, and loss of carnitine degradation pathways in IBD. Finally, we observed novel and significant differences in the gene carriage among both IBD- and non-IBD-associated taxa, suggesting that strain-specific functional variation may contribute to pathogenesis and disease-related bacterial fitness. Microbial clades responsible for IBD-linked dysbiosis are not uniform, and their functionality in IBD and CD/UC subsets are driven by species and strain lineage-specific variants."

Although pesticides, industrial solvents, heavy metals, and air pollutants have long been implicated as potentially modifiable PD risk factors, climate change is now reshaping and amplifying these hazards through rising temperatures, worsening air quality, increased pesticide demand, extreme weather events, and wildfire-related particulate matter.This narrative review moves beyond a conventional exposure-based summary by integrating environmental toxicology, climate science, epidemiology, and mechanistic neuroscience to reframe PD risk within the context of planetary health. We summarize evidence linking major environmental hazards to PD pathogenesis, emphasizing convergent mechanisms such as oxidative stress, mitochondrial dysfunction, impaired proteostasis, neuroinflammation, blood-brain barrier disruption, and \u03b1-synuclein aggregation. We further discuss how climate-related changes may intensify these pathways and disproportionately affect vulnerable populations, including agricultural workers, older adults, socioeconomically disadvantaged communities, and individuals living in rapidly industrializing or climate-sensitive regions. Importantly, we highlight clinical and public health implications by proposing that structured environmental and occupational exposure assessment should be incorporated into PD risk evaluation, early recognition, preventive counseling, and research design. We also discuss exposure reduction, workplace protection, environmental monitoring, and regulatory policy as prevention-oriented strategies. By positioning environmental hazards and climate change as interconnected, underrecognized, and potentially modifiable contributors to PD, this review provides a framework for clinicians, researchers, and policymakers seeking to reduce the future global burden of neurodegenerative disease. Parkinson's disease (PD) is a common neurodegenerative disorder that develops over time and affects movement, balance, and many daily activities. While genes play a role, most cases of PD do not arise solely from genetics. Growing evidence shows that environmental exposures, such as pesticides, industrial chemicals, heavy metals, and air pollution, can increase the risk of developing PD. Importantly, many of these exposures can be reduced or prevented. Climate change is worsening these environmental risks. Higher temperatures, poorer air quality, increased pesticide use, and more frequent wildfires are increasing human exposure to harmful pollutants worldwide. Together, these changes may increase the number of people affected by PD, especially in communities already facing environmental or social disadvantages. This review explains how environmental toxins can damage brain cells through shared biological processes, including oxidative stress, inflammation, and abnormal protein buildup. It also highlights regions and populations that may be more vulnerable to these risks. From a healthcare perspective, understanding a person's environmental and work-related exposures can help identify those at higher risk, support earlier recognition of PD, and guide prevention advice. Overall, environmental toxins and climate change are underrecognized yet actionable determinants of PD. Increasing awareness, improving environmental protections, and integrating exposure history into clinical care are key steps toward reducing the future global burden of PD."

Achieving this response is especially challenging with inactivated or subunit vaccines, which lack the ability of live-attenuated formulations to mimic the natural infection process needed to induce strong intestinal mucosal immunity. Specifically, the inactivated polio vaccine (IPV), administered parenterally, elicits strong systemic immunity but fails to induce the mucosal IgA responses required to fully block poliovirus transmission, a critical step toward complete eradication. To address this limitation, we developed a clinically translatable and scalable nanoparticle-based intestinal mucosal adjuvant by encapsulating Am80, a small hydrophobic molecule known to promote intestinal mucosal immunity, within nanoparticles (NPs) designed for lymph node delivery, without requiring antigen modification, encapsulation, or adsorption. Encapsulation in NPs eliminated the need for the use of organic solvents, reduced toxicity, and prevented degradation, while lipid nanoparticles (Am80-LNPs) were engineered for sustained release over 3 to 5 days with high encapsulation efficiency (78\u00a0\u00b1\u00a09%). Cy5-labeled Am80-LNPs localized to draining lymph nodes within 6 hours and were retained for up to 72 hours. Coadministration of Am80-LNPs with the licensed IPV-2 in a Wistar rat model significantly boosted IPV-2-specific fecal IgA by 20-fold compared to IPV-2 alone and threefold over free Am80. These findings demonstrate that Am80-LNPs significantly enhance IPV-2-specific mucosal immunity in vivo and suggest their potential as a potent mucosal adjuvant against other enteric pathogens."

While specific toxicological pathways regarding organic solvents and MS are subject to ongoing investigation, current epidemiological evidence suggests associations between lung irritant exposures\u2014including organic solvents\u2014and MS risk, particularly in genetically susceptible individuals.\n\n### [INTRODUCTION & JUSTIFICATION]\nMultiple Sclerosis is a chronic, immune-mediated neurodegenerative disorder. Its development is understood to be the result of a convergence between an individual's genetic architecture and a variety of environmental exposures. Research into non-infectious determinants has expanded to include diverse occupational and environmental pollutants. The literature indicates that \"The trajectory of multiple sclerosis (MS) is shaped by complex interactions between genetic susceptibility and environmental factors.\" Among these factors, \"Exposure to lung irritants such as smoking and organic solvents has been associated with increased risk of multiple sclerosis (MS), particularly among genetically susceptible individuals.\" This association is reinforced by findings that \"Industrial dust exposure was associated with increased rate of MS (OR 1.30, 95% CI 1.05-1.63), with a dose-response relationship with duration (OR per 1-year exposure 1.03, 95% CI 1.00-1.06).\" When these occupational factors overlap with known genetic markers, the risk profiles appear to compound, as seen where \"Participants who smoked, were exposed to dust, and carried the HLA-DRB1*15:01 allele had an 11-fold increased rate of MS (OR 11.1, 95% CI 5.7-21.9), compared with those without any of these risk factors.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Current evidence indicates that occupational inhalation risks are not limited to single substances but often involve synergistic effects with smoking.\n*   Genetic susceptibility, particularly the HLA-DRB1*15:01 allele, acts as a significant amplifier for risks posed by environmental irritants.\n*   The literature consistently highlights that MS risk involves \"complex interactions between genetic susceptibility and environmental factors.\"\n*   Epidemiological models have successfully utilized large-scale population data to identify dose-response relationships between industrial environmental exposures and MS incidence.\n*   Standard diagnostic criteria (McDonald criteria) are utilized in prospective and case-control studies to ensure the validity of clinical cohorts.\n*   There is a clear distinction in the literature between established MS risk factors (like smoking and dust) and other suspected occupational exposures that require further investigation.\n*   The interplay between occupational environments and MS implies that preventative workplace strategies may be a viable public health intervention.\n*   Data scarcity and participant heterogeneity often hamper prognostic modeling, but new sensory technologies are being explored to better categorize personal exposure patterns.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

While the exact molecular etiology remains complex, evidence from multiple population-based case-control studies indicates a statistically significant association between solvent exposure and MS risk. Furthermore, this relationship appears to be modified by additional risk factors, notably cigarette smoking and specific genetic alleles.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nEnvironmental exposures, including organic solvents, serve as modifiable risk factors that contribute to MS pathogenesis. These agents likely interact with the host immune system through proinflammatory pathways, potentially synergizing with genetic predisposition and other environmental triggers, such as smoking, to amplify the risk of MS development.\n\n### [INTRODUCTION & JUSTIFICATION]\nMultiple sclerosis is recognized as a complex neuroinflammatory disease resulting from the convergence of genetic susceptibility and environmental factors. Among these, organic solvents have been identified as contributors to disease risk, though determining the precise mechanisms of such environmental triggers remains a challenge. Current evidence suggests that solvent exposure acts as an irritant, potentially inducing inflammatory responses that may contribute to the loss of immune tolerance in genetically predisposed individuals. The interaction between solvent exposure and other risks, such as smoking, suggests that these environmental agents may share similar proinflammatory or neurotoxic outcomes. Despite the lack of fully elucidated causative mechanisms for every environmental factor, the cumulative evidence from longitudinal and case-control studies reinforces the association between chemical environmental exposures and MS risk.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Exposure to organic solvents is dose-dependently associated with an increased risk of MS.\n*   The association between organic solvent exposure and MS is frequently found to be dependent on concurrent smoking status.\n*   Genetic interaction analyses reveal that solvent exposure, when combined with HLA risk genes, may influence adaptive immunity.\n*   The proinflammatory and neurotoxic effects of solvents like organic compounds and particulate matter may overlap with other industrial hazards like engine exhaust.\n*   The association between solvents and MS is supported by studies in diverse populations, including those in Sweden and the UK.\n*   Despite clinical evidence, some studies on specific airborne pollutants have yielded contradictory results, highlighting the complexity of environmental epidemiological research.\n*   Methodological tools like MALDI-imaging have advanced our ability to track lipid alterations in demyelinating conditions, which may be impacted by environmental factors.\n*   Research on the exposome and potential preventative strategies highlights the importance of acting on known modifiable risk factors like smoking and environmental pollutants to protect brain health.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

While organic solvents are recognized as generic respiratory and industrial irritants associated with neuro-immune dysfunction, the specific causality regarding MS pathogenesis requires further differentiation from broader industrial dust and smoking-related risk factors.\n\n### [INTRODUCTION & JUSTIFICATION]\nMultiple Sclerosis (MS) is defined by the convergence of polygenic immune susceptibility and external triggers. The literature indicates that \"Multiple sclerosis (MS) arises from the convergence of polygenic immune susceptibility, environmental exposures, and infectious determinants, none of which alone is sufficient for disease expression.\" Within this framework, organic solvents are often studied alongside other pulmonary irritants. Epidemiological data suggests that \"Exposure to lung irritants such as smoking and organic solvents has been associated with increased risk of multiple sclerosis (MS), particularly among genetically susceptible individuals.\" This relationship is mechanistically supported by the concept of a lung-brain axis, where \"A pathway-based framework is presented in which lung inflammation, systemic cytokine release, oxidative stress, blood-brain barrier disruption, immune priming, and protein misfolding mediate lung-to-brain communication.\" Because solvents typically induce systemic oxidative stress, they contribute to the broader landscape of inflammatory pathology.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   The interaction between environmental solvents and the HLA-DRB1*15:01 allele is a critical, synergistic factor that amplifies MS risk significantly compared to independent effects.\n*   \"Participants who smoked, were exposed to dust, and carried the HLA-DRB1*15:01 allele had an 11-fold increased rate of MS (OR 11.1, 95% CI 5.7-21.9), compared with those without any of these risk factors.\"\n*   Biocompatible, solvent-free synthesis methods are emerging as a critical green-chemistry counter-strategy to mitigate the environmental burdens associated with chemical manufacturing.\n*   \"Lignin-ferric nanoparticles (LS-Fe) were prepared through an aqueous one-pot process using sodium lignosulfonate (SLS) as the lignin precursor and Fe3\u207a as the coordination component, without the use of organic solvents.\"\n*   The pathophysiology of MS comorbidities often involves shared risk factors; thus, environmental solvent exposure may not just influence MS but also the systemic susceptibility to associated autoimmune conditions.\n*   \"Moreover, AMPA have been associated with genetic and environmental risk factors in RA, including human leukocyte antigen (HLA) alleles, smoking, and microbial exposure.\"\n*   Chronic exposure to solvents is increasingly viewed through the lens of developmental origins, where early-life vulnerability creates long-term susceptibility to neurodegeneration.\n*   \"Environmental risk factors for MS are important during childhood and adolescence. The first 20 years are a key window for prevention and should be seen as an opportunity.\"\n*   There is a clear methodological shift in chemistry to replace \"harmful and expensive organic solvents\" with aqueous-based or enzymatic processes to reduce ecological and occupational health hazards.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

This review examines modifiable non-infectious determinants across the life course and proposes integrated prevention strategies. Key factors include vitamin D deficiency, low UV exposure, smoking, adolescent obesity, air pollution, and chemical environmental exposures. Mendelian randomization studies support the causality of several determinants, particularly low vitamin D and high BMI. Adolescence emerges as a critical susceptibility window where the maturing immune system is uniquely sensitive to metabolic and environmental triggers. Among validated interventions, vitamin D supplementation stands out for its ability to reduce disease activity in early MS. Effective prevention requires both individual actions and structural public health policies, such as air quality regulations and urban \"walkability\". Future efforts should prioritize multimodal strategies targeting high-risk youths through the educational system (physical activity, weight management, and smoking prevention). These holistic approaches offer broad-spectrum benefits, reducing the burden of MS while preventing comorbidities, including cardiovascular, metabolic but also cancer."

We conducted a Swedish population-based case-control study. Patients with incident MS age 16-70 years were consecutively identified by neurologists at 40 clinics (2005-2015). Eligibility criteria for participants were age 16-70 years, residence in Sweden, and a neurologist-confirmed diagnosis of MS according to the McDonald criteria.

Here, we review current evidence for the involvement of EBV in MS, its impact on existing therapeutics, and strategies for novel therapeutic directions. Compelling evidence indicates EBV infection precedes MS onset, likely contributing to disease initiation, relapses, and possibly progression through mechanisms such as molecular mimicry, B cell immortalization, and viral reactivation. Current MS therapies may indirectly suppress EBV by depleting B cells or restricting lymphocyte CNS entry. Novel strategies, including CAR-T/-NK cells, adoptive T cells, \"kick and kill\" approaches, and vaccines, aim to directly target EBV and offer promising new avenues for MS therapy."

Epstein-Barr virus (EBV) infection has been implicated as a major environmental risk factor in MS pathogenesis. Despite the availability of disease-modifying therapies, effective targeted interventions for progressive disease remain limited. In this study, an EBV-informed integrative computational framework combining MS transcriptomic datasets, EBV-associated transcriptional signatures, GWAS susceptibility genes, and network analyses was employed to identify molecular targets associated with immune dysregulation in MS. RNA-sequencing datasets related to MS and EBV infection were obtained from the GEO database, whereas MS susceptibility genes were retrieved from the GWAS Catalog. Differential expression analysis identified 275, 200, and 773 significant DEGs in CD4\u207a T cells, CD8\u207a T cells, and CD14\u207a monocytes, respectively, along with 8,633 EBV-associated DEGs. Integrative overlap and enrichment analyses revealed convergence at the pathway level, particularly involving B-cell receptor signaling, Fc receptor activation, antigen presentation, complement activation, and inflammatory immune signaling. Hub gene analysis identified IL6, CD86, CD28, and PTPN11 as central regulatory nodes. Based on biological relevance and structural tractability, PTPN11/SHP2 was selected as the final therapeutic target. Structure-based drug repurposing identified Gusperimus as the top-ranked ligand, exhibiting a favorable docking score (-\u20099.287\u00a0kcal/mol) and a broader interaction profile within the SHP2 allosteric pocket relative to the reference inhibitor SHP099 (-\u20097.915\u00a0kcal/mol). Molecular dynamics simulations supported stable occupancy of the SHP2 allosteric pocket by Gusperimus over a 100 ns trajectory. Collectively, these findings highlight SHP2 as a potential therapeutic target and identify Gusperimus as a candidate for further investigation in MS-associated immune dysregulation."

Shift work disrupts circadian rhythms and is a potential occupational risk factor for MS, with exposure before age 20 thought to be of additional risk. To investigate associations between retrospective lifetime shift work exposure and MS diagnosis and between prospective shift work exposure and incident MS over 13 years of follow-up in the UK Biobank cohort. Participants that were in work and free of MS at baseline were followed up for 13 years, and lifetime exposure to night, day and mixed shift work was assessed in a subset of participants. Logistic regression and Cox proportional hazard models were applied to test associations between shift work and MS diagnosis, controlling for demographic and lifestyle confounders. Lifetime exposure to mixed, day or night shift work was not associated with an increased risk of MS diagnosis. No significant associations were observed for early-life shift work exposure or in prospective analysis of those reporting shift work at baseline. Factors such as female sex, smoking, childhood obesity and reduced sunlight exposure were consistently associated with higher MS risk. There was no evidence for an association between shift work and the risk of MS diagnosis in this cohort, in retrospective analysis of lifetime exposure or in prospective studies of shift work at baseline following 13 years of follow-up.

Environmental risk factors, such as vitamin D deficiency and obesity, have also been implicated in multiple sclerosis pathogenesis. Statistical approaches building on these genetic data, such as Mendelian randomization and co-localization, have established putative causal links between environmental risk factors and multiple sclerosis risk, most notably for vitamin D and body mass index. However, studies have thus far revealed limited statistically significant interactions between host genetics and environmental factors beyond the major histocompatibility complex. Epigenetics (the study of non-nucleotide alterations to DNA, such as DNA methylation or histone acetylation) might provide a mechanistic framework for understanding how environmental and genetic factors interact in multiple sclerosis. Environmental factors, such as Epstein-Barr virus infection, vitamin D deficiency and smoking, are associated with epigenetic modifications at key multiple sclerosis-related genomic loci, altering the expression of multiple sclerosis risk genes in a cell type-specific manner. Transcriptomics have identified significant pathways via which genetic risk is realized, potentially providing targets for intervention. This review synthesizes current evidence on gene-environment interactions in the context of multiple sclerosis genome-wide association study findings, evaluates the strengths and limitations of various study methodologies, and discusses the challenges in elucidating the interplay between genetics and environmental factors. We propose potential strategies for future research to advance our understanding of the biological mechanisms underlying multiple sclerosis susceptibility in at-risk individuals."

Cumulative lifetime exposures (i.e. the exposome) contribute to ILD onset and progression by interacting with genetic susceptibility and influencing multiple molecular pathways. This review summarizes current evidence evaluating how environmental exposures interact across the genome, epigenome, transcriptome, proteome, metabolome, and microbiome to drive ILD pathogenesis. Environmental exposures, including air pollution, influence ILD risk through interactions with genetic factors that modify disease susceptibility. Epigenetic mechanisms, particularly DNA methylation, reflect key pathways through which exposures may contribute to ILD onset and progression and serve as sensitive biomarkers of environmental injury. Exposure-associated molecular alterations can be detected across multiple omic layers, including transcriptomic, proteomic, and metabolomic profiles. In parallel, exposures like cigarette smoking, silica, and air pollution influence the respiratory microbiome, with potential downstream effects on immune responses and fibrogenesis. Integrating these findings highlights environmentally-sensitive pathways that may represent novel targets for therapeutic modulation. Integration of exposomic and multiomic molecular frameworks offers new opportunities to improve ILD risk stratification, prognostication, and precision therapeutic development, while also strengthening our mechanistic understanding of environmentally-mediated disease."

Aquatic foods are important components of dietary diversification, but their association with internal PFAS burden remains unclear in inland populations. Of the 1294 participants initially recruited, 1292 with complete demographic information were included in the final analyses. Serum concentrations of 22 PFASs were measured by solid-phase extraction coupled with UPLC-MS/MS, and nine PFASs detected in more than 75% of samples were analyzed. Dietary intake frequency, sociodemographic characteristics, and lifestyle factors were collected using structured questionnaires. Multivariable linear regression and sex-stratified analyses were performed. Seafood-related food groups showed the most consistent positive associations with serum PFAS levels. Frequent consumption of shellfish, shrimp, crabs, fish, and seaweed was associated with higher concentrations of long-chain PFASs, including PFDA, PFNA, PFHxS, PFOS, and PFOA, while shrimp and crab intake was also positively associated with 6:2 Cl-PFESA. These associations were generally stronger in males, suggesting sex-related heterogeneity in the relationship between seafood intake and PFAS body burden.

In this study, technical alkali lignin from soda bagasse was ozonated in ethanol, tetrahydrofuran (THF), 1,4-dioxane, acetone, or methyl cellosolve to combine oxidative depolymerization with solvent fractionation. The comparison tested how solvent polarity and hydrogen-bonding behavior affect product distribution under otherwise fixed conditions. FTIR, GPC, and GC-MS showed differences among the five soluble fractions. Protic solvents retained more phenolic monomers and oligomers, whereas aprotic solvents gave more oxidized products and different H:G:S profiles. The ethanol fraction had the highest apparent thermal stability (Ea\u00a0=\u00a04.14\u00a0kJ/mol; DTG peak\u00a0=\u00a0380\u00a0\u00b0C) and the lowest Mw (856\u00a0Da). Methyl cellosolve produced the highest-Mw fraction (2985\u00a0Da) and a more balanced H:G:S distribution. Guaiacol accounted for 40.6% of the ethanol fraction, coumaran for 70.4% of the THF fraction, and syringol for 17.2% of the methyl cellosolve fraction. THF-only controls did not produce a peak assigned to coumaran in the relevant retention-time window, which supports a lignin-derived origin for this signal under the tested conditions. The screening results link solvent properties to lignin fragmentation and the composition of the soluble products. Solvent recycling, residue characterization, process optimization, and atom-resolved mechanistic studies remain to be completed."

Network toxicology identified 252 shared targets between sleep-related environmental pollutants (SREPs: NO2, formaldehyde, benzene) and SD. PPI network and diagnostic model identified four hub genes (HSP90AA1, RELA, PTGS2, MMP9) with moderate-to-high predictive value (AUC: 0.708-0.979). Immune infiltration analysis showing elevated T cells and reduced astrocytes and neurons in patients with SD. Molecular simulations confirmed stable SREP-hub protein binding, with benzene exhibiting the highest affinity. Crucially, mixed SREPs exposure induced more severe toxicity than individual pollutants, demonstrating true synergistic disruption. In vivo, SREPs metabolites disrupted sleep architecture, impaired the blood-brain barrier (BBB), and induced neurobehavioral deficits. In vitro studies using brain endothelial cells (BMVECs) revealed that SREPs directly increase permeability, suppress tight junctions, and activate a pro-inflammatory cascade involving NF-\u03baB signaling, enhanced MMP9 activity, and prostaglandin E2 synthesis. Curcumin intervention effectively counteracted these effects, restoring BBB integrity, normalizing sleep patterns, and suppressing hub gene expression and neuroinflammation in vivo and in vitro by targeting the identified hub gene network. Our integrated computational-experimental strategy establishes a novel \"pollutant-BBB-neuroimmune-sleep\" axis, providing a mechanistic framework for assessing cumulative environmental risks and advancing targeted interventions."

Existing studies have confirmed that evodiamine, rutaecarpine and other alkaloids induce hepatotoxicity via multi-pathways, but the core toxic fraction, multi-component synergistic effects and systematic toxic network of EF remain unclear. This study aims to identify the key hepatotoxic fraction of Evodiae Fructus (EF) and elucidate its underlying mechanisms. A high-throughput zebrafish model was used to screen EF extracts with different polar solvents. The hepatotoxicity of the target fraction was validated in mice. UPLC-Q-TOF-MS/MS, integrated network pharmacology, proteomic and transcriptomic analyses were performed in zebrafish and mice to screen toxic pathways, with western blot and qRT-PCR validation. High-throughput zebrafish screening of five polar extracts of EF identified the dichloromethane extract (DEEF) as the core hepatotoxic fraction. Both zebrafish and mouse models consistently indicated that DEEF induced a dose-dependent elevation of serum ALT, AST, and TBA levels, disrupted the architecture of hepatic tissue, and was accompanied by marked hepatocyte apoptosis. In mice, Masson's trichrome staining further revealed abnormal collagen deposition, along with extensive infiltration of inflammatory cells. UPLC-Q-TOF-MS/MS analysis identified 73 compounds in DEEF, with 48 alkaloids (indole and quinolone types) being the dominant components, in addition to flavonoids, limonoids, and organic acids. Integrated network pharmacology, transcriptomic and proteomic analyses revealed dose-dependent global alterations in hepatic gene and protein expression profiles. Mechanistically, DEEF upregulated bile acids (BAs) synthesis enzymes (CYP7A1, CYP27A1) and downregulated efflux transporters (BSEP, MRP2). These changes were associated with activation of PI3K-AKT/MAPK/p53/NF-\u03baB pathways and modulation of the Bax/Bcl-2/Caspase-3 apoptotic axis, as indicated by multi-omics enrichment and validated by protein and gene expression analyses.

Therefore, continuous doping control is essential for maintaining fairness and athlete's safety. Accurate and rapid detection of prohibited substances at their lowest levels in complex biological matrices, such as blood, urine, and plasma, is crucial for reliable anti-doping analysis. This critical review focuses on the applications of mass spectrometry (MS) for the detection of doping agents across diverse biological matrices. Special emphasis is given to advanced mass spectrometry platforms, particularly LC-QQQ-MS, LC-QTOF-MS, Orbitrap-MS/MS, and IRMS which are widely used for the routine screening, confirmation, and identification of emerging doping agents. Microsampling approaches such as dried blood spots (DBS) and volumetric absorptive microsampling (VAMS) provide superior alternatives to traditional sampling. Furthermore, comprehensive understanding of sample pretreatment and analytical techniques is essential. In this regard, novel microextraction techniques, including solid-phase microextraction (SPME), liquid-phase microextraction (LPME), supramolecular solvents (SUPRAS), and deep eutectic solvents (DES), have improved multi-analyte sample pretreatment strategies and facilitated advanced automation.

Their reliable determination depends strongly on efficient sample preparation, but conventional organic solvent extraction often raises concerns related to solvent consumption, toxicity, selectivity, and sample-cleanup burden. Deep eutectic solvents (DESs) have been widely explored as tunable extraction media for phenolic compounds because their polarity, viscosity, hydrogen-bonding capacity, and solvation behavior can be adjusted by changing the hydrogen-bond acceptor, hydrogen-bond donor, molar ratio, and water content. However, conventional DES systems still face important limitations, including slow mass transfer caused by high viscosity, difficulty in solvent removal due to low volatility, incomplete analyte recovery, and possible interference with chromatographic or mass-spectrometric analysis. This review summarizes conventional DES-based extraction of phenolic compounds as the baseline, and then focuses on responsive switchable DESs (RS-DESs) as recovery-oriented solvent systems. RS-DESs can undergo reversible changes in phase behavior, polarity, miscibility, or solvation ability in response to temperature, pH, CO2/N2, or ionic strength, thereby facilitating extraction, phase separation, analyte recovery, and solvent recycling. Particular attention is paid to extraction mechanisms, structure-property relationships, quantitative comparison with conventional DES systems, and analytical compatibility with HPLC, LC-MS, and related sample-cleanup workflows. Finally, the review discusses current scientific, analytical, and industrial challenges, including switching reproducibility, phenolic stability, DES residues, matrix effects, toxicity, biodegradability, and scale-up feasibility."

Growing evidence indicates that nutrition, environment, and lifestyle significantly influence disease development, progression, and treatment response. Nutrients such as vitamins, minerals, omega-3 fatty acids, and polyphenols affect neuroinflammation, oxidative stress, mitochondrial health, and neurotransmitter function. Dietary patterns like the Mediterranean and ketogenic diets offer protective benefits in clinical and experimental contexts. Meanwhile, environmental neurotoxicants-air pollution, heavy metals, pesticides, and endocrine disruptors contribute to neurodegeneration via oxidative damage, synaptic impairment, and epigenetic alterations. Lifestyle factors, such as physical activity, sleep, stress, and substance use, affect brain plasticity, neurogenesis, and metabolic health, thereby influencing disease progression over time. These factors often share common pathways such as oxidative stress, inflammation, vascular injury, mitochondrial dysfunction, and protein misfolding, underscoring the need for a comprehensive prevention and treatment strategy. Emerging therapies now incorporate personalized nutrition, lifestyle changes, and environmental risk mitigation alongside traditional drugs, supported by advances in multi-omics, digital health, and systems biology. Public health efforts to reduce neurotoxic exposure and encourage healthy habits further strengthen these approaches.

While specific toxicological pathways regarding organic solvents and MS are subject to ongoing investigation, current epidemiological evidence suggests associations between lung irritant exposures\u2014including organic solvents\u2014and MS risk, particularly in genetically susceptible individuals.\n\n### [INTRODUCTION & JUSTIFICATION]\nMultiple Sclerosis is a chronic, immune-mediated neurodegenerative disorder. Its development is understood to be the result of a convergence between an individual's genetic architecture and a variety of environmental exposures. Research into non-infectious determinants has expanded to include diverse occupational and environmental pollutants. The literature indicates that \"The trajectory of multiple sclerosis (MS) is shaped by complex interactions between genetic susceptibility and environmental factors.\" Among these factors, \"Exposure to lung irritants such as smoking and organic solvents has been associated with increased risk of multiple sclerosis (MS), particularly among genetically susceptible individuals.\" This association is reinforced by findings that \"Industrial dust exposure was associated with increased rate of MS (OR 1.30, 95% CI 1.05-1.63), with a dose-response relationship with duration (OR per 1-year exposure 1.03, 95% CI 1.00-1.06).\" When these occupational factors overlap with known genetic markers, the risk profiles appear to compound, as seen where \"Participants who smoked, were exposed to dust, and carried the HLA-DRB1*15:01 allele had an 11-fold increased rate of MS (OR 11.1, 95% CI 5.7-21.9), compared with those without any of these risk factors.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Current evidence indicates that occupational inhalation risks are not limited to single substances but often involve synergistic effects with smoking.\n*   Genetic susceptibility, particularly the HLA-DRB1*15:01 allele, acts as a significant amplifier for risks posed by environmental irritants.\n*   The literature consistently highlights that MS risk involves \"complex interactions between genetic susceptibility and environmental factors.\"\n*   Epidemiological models have successfully utilized large-scale population data to identify dose-response relationships between industrial environmental exposures and MS incidence.\n*   Standard diagnostic criteria (McDonald criteria) are utilized in prospective and case-control studies to ensure the validity of clinical cohorts.\n*   There is a clear distinction in the literature between established MS risk factors (like smoking and dust) and other suspected occupational exposures that require further investigation.\n*   The interplay between occupational environments and MS implies that preventative workplace strategies may be a viable public health intervention.\n*   Data scarcity and participant heterogeneity often hamper prognostic modeling, but new sensory technologies are being explored to better categorize personal exposure patterns.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

However, it remains unclear whether LOMS differs etiologically from adult-onset multiple sclerosis (AOMS). To determine whether established MS risk factors differ between LOMS and AOMS and influence age at onset. We conducted a Swedish population-based case-control study including 3950 incident MS cases and 7340 controls. Cases were classified as LOMS (n\u2009=\u2009396) or AOMS (n\u2009=\u20093554). Associations between risk factors and LOMS and AOMS were estimated using logistic regression. Case-only analyses assessed associations with age at onset. Most MS risk factors, including MS heredity, HLA-DRB1*15:01, Epstein-Barr nuclear antigen (EBNA)-1 antibody levels, smoking, and low sun exposure, were associated with both onset groups, with stronger effects in AOMS. Elevated body mass index at age 20\u2009years was associated with AOMS, while estimates in LOMS were imprecise. Case-only analyses showed no association with disease timing. Exposure distribution varied across birth cohorts, suggesting cohort effects. Established MS risk factors appear to be more clearly related to disease susceptibility than to timing of onset. The broadly consistent risk factor profiles support a shared etiology, although modest differences cannot be excluded.\n\nID: 42541988\nTitle: Epstein-Barr virus and multiple sclerosis: Mechanisms, therapeutic implications, and emerging interventions.\nAbstract: Multiple sclerosis (MS) is a neuroinflammatory disease shaped by genetic and environmental factors, with Epstein-Barr virus (EBV) emerging as the strongest environmental risk. Here, we review current evidence for the involvement of EBV in MS, its impact on existing therapeutics, and strategies for novel therapeutic directions. Compelling evidence indicates EBV infection precedes MS onset, likely contributing to disease initiation, relapses, and possibly progression through mechanisms such as molecular mimicry, B cell immortalization, and viral reactivation. Current MS therapies may indirectly suppress EBV by depleting B cells or restricting lymphocyte CNS entry. Novel strategies, including CAR-T/-NK cells, adoptive T cells, \"kick and kill\" approaches, and vaccines, aim to directly target EBV and offer promising new avenues for MS therapy.\n\nID: 42539597\nTitle: AI-based predictive biomarkers for chronic neurological diseases: the rAIdD prospective, multicenter, observational study protocol.\nAbstract: Chronic neurological disorders such as Multiple Sclerosis (MS), Parkinson's disease (PD), and Alzheimer's Disease (AD) represent a major global health burden characterized by progressive neurodegeneration, functional disability, and cognitive decline. Despite differences in etiology and clinical presentation, these conditions share multifactorial pathophysiological mechanisms influenced by genetic, environmental, and lifestyle-related factors. Advances in artificial intelligence (AI), wearable technologies, and multimodal clinical data integration offer new opportunities for identifying predictive digital biomarkers and improving personalized disease management. The rAIdD project (\"eHealth Network: AI and new ICT technology equipment for digital diagnosis\") aims to develop an interoperable digital infrastructure to support early diagnosis, monitoring, and risk stratification in chronic neurological diseases. This study protocol describes the neurological component of the rAIdD network focusing on MS, PD, and AD. This prospective, multicenter, observational study involves six Italian academic and clinical centers and will enroll 780 participants: 300 MS, 150 PD, 150 AD, and 180 healthy controls. Participants will be followed for 18 months within a 48-month study period. Standardized clinical, neuropsychological, neuroimaging, and digital assessments will be performed at baseline and at 6-, 12-, and 18-month follow-ups. Clinical evaluation includes disease-specific disability and functional scales, mood and quality-of-life assessments, and lifestyle and environmental risk factor profiling. Continuous digital monitoring will be conducted using wearable sensors to collect biometric and behavioral data, including physical activity, sleep patterns, and cardiovascular parameters. Structural neuroimaging will be acquired longitudinally and integrated with clinical and digital data through a centralized web-based electronic data capture platform. Machine learning approaches will be applied to identify multimodal predictive biomarkers and model disease progression patterns across disorders. The study has been approved by the Ethics Committee of the coordinating center and by local ethics committees of all participating institutions. Written informed consent is obtained from all participants in accordance with the Declaration of Helsinki and the General Data Protection Regulation (GDPR 2016/679). Results will be disseminated through peer-reviewed publications, scientific conferences, and digital communication platforms to support knowledge translation and implementation of precision neurology approaches.\n\nID: 42431827\nTitle: Lifetime exposure to shift work and risk of multiple sclerosis: retrospective and prospective cohort studies in UK Biobank.\nAbstract: Multiple sclerosis (MS) is an autoimmune disease with complex aetiology involving genetic, environmental and lifestyle factors. Shift work disrupts circadian rhythms and is a potential occupational risk factor for MS, with exposure before age 20 thought to be of additional risk. To investigate associations between retrospective lifetime shift work exposure and MS diagnosis and between prospective shift work exposure and incident MS over 13 years of follow-up in the UK Biobank cohort. Participants that were in work and free of MS at baseline were followed up for 13 years, and lifetime exposure to night, day and mixed shift work was assessed in a subset of participants. Logistic regression and Cox proportional hazard models were applied to test associations between shift work and MS diagnosis, controlling for demographic and lifestyle confounders. Lifetime exposure to mixed, day or night shift work was not associated with an increased risk of MS diagnosis. No significant associations were observed for early-life shift work exposure or in prospective analysis of those reporting shift work at baseline. Factors such as female sex, smoking, childhood obesity and reduced sunlight exposure were consistently associated with higher MS risk. There was no evidence for an association between shift work and the risk of MS diagnosis in this cohort, in retrospective analysis of lifetime exposure or in prospective studies of shift work at baseline following 13 years of follow-up. Further research is needed to elucidate mechanisms and latitudinal variations in shift work-related MS risk.\n\nID: 42420581\nTitle: EBV-informed multi-omics target prioritization and structure-based drug repurposing reveal potential therapeutic strategies for multiple sclerosis.\nAbstract: Multiple sclerosis (MS) is a chronic neuroinflammatory disorder characterized by progressive neurodegeneration, demyelination, and genetic susceptibility. Epstein-Barr virus (EBV) infection has been implicated as a major environmental risk factor in MS pathogenesis. Despite the availability of disease-modifying therapies, effective targeted interventions for progressive disease remain limited. In this study, an EBV-informed integrative computational framework combining MS transcriptomic datasets, EBV-associated transcriptional signatures, GWAS susceptibility genes, and network analyses was employed to identify molecular targets associated with immune dysregulation in MS. RNA-sequencing datasets related to MS and EBV infection were obtained from the GEO database, whereas MS susceptibility genes were retrieved from the GWAS Catalog. Differential expression analysis identified 275, 200, and 773 significant DEGs in CD4\u207a T cells, CD8\u207a T cells, and CD14\u207a monocytes, respectively, along with 8,633 EBV-associated DEGs. Integrative overlap and enrichment analyses revealed convergence at the pathway level, particularly involving B-cell receptor signaling, Fc receptor activation, antigen presentation, complement activation, and inflammatory immune signaling. Hub gene analysis identified IL6, CD86, CD28, and PTPN11 as central regulatory nodes. Based on biological relevance and structural tractability, PTPN11/SHP2 was selected as the final therapeutic target. Structure-based drug repurposing identified Gusperimus as the top-ranked ligand, exhibiting a favorable docking score (-\u20099.287\u00a0kcal/mol) and a broader interaction profile within the SHP2 allosteric pocket relative to the reference inhibitor SHP099 (-\u20097.915\u00a0kcal/mol). Molecular dynamics simulations supported stable occupancy of the SHP2 allosteric pocket by Gusperimus over a 100 ns trajectory. Collectively, these findings highlight SHP2 as a potential therapeutic target and identify Gusperimus as a candidate for further investigation in MS-associated immune dysregulation.\n\nID: 42394741\nTitle: Reproductive, Dietary, and Physical Activity Factors Associated With Multiple Sclerosis: A Case-Control Study.\nAbstract: Multiple sclerosis (MS) is a chronic inflammatory disease influenced by genetic and environmental factors. Dietary habits, reproductive characteristics, and physical activity have been proposed as potential contributors to MS susceptibility. This study aimed to investigate the association of dietary intake, supplement use, reproductive factors, and physical activity with MS in Kermanshah Province, Iran. This case-control study included 600 participants (300 MS patients and 300 matched healthy controls) from Kermanshah. Data were collected using the validated Persian version of the Environmental Exposure and Lifestyle Risk Factors in MS Questionnaire (EnvIMS-Q). Logistic regression analyses were performed to estimate crude and adjusted odds ratios (ORs) with 95% confidence intervals (CIs). Compared with controls, participants with MS reported lower consumption of several foods, including fish (adjusted OR\u2009=\u20090.31, 95% CI 0.19-0.50), seafood (adjusted OR\u2009=\u20090.31, 95% CI 0.10-0.98), nuts (adjusted OR\u2009=\u20090.60, 95% CI 0.39-0.93), and dairy products. Fish oil supplementation was less common among patients with MS (adjusted OR\u2009=\u20090.28, 95% CI 0.13-0.61). Female patients reported higher frequencies of oral contraceptive use, miscarriage, and assisted reproduction. Vigorous physical activity was significantly lower among patients than controls, whereas mild physical activity did not differ significantly. No significant association was observed for vitamin D supplementation. This study identified associations between several dietary, reproductive, and lifestyle factors and MS in a high-prevalence region of Iran. Lower consumption of selected nutrient-rich foods, lower fish oil supplement use, certain reproductive factors, and lower levels of vigorous physical activity were associated with higher odds of MS. Prospective studies are needed to clarify temporal relationships and causality.\n\nID: 42343804\nTitle: [Mining of ancestral lipases and enzymatic synthesis of amides].\nAbstract: The amide bond plays a crucial role in the synthesis of proteins, pharmaceuticals, and agrochemicals. It is particularly significant in the pharmaceutical field as a key structural unit in many drugs, such as afatinib (an anticancer drug), teriflunomide (used for multiple sclerosis treatment), acebutolol (used for hypertension and arrhythmia treatment), and paracetamol (an antipyretic and analgesic agent). However, chemical synthesis methods usually require harsh reaction conditions (e.g., high temperature, high pressure, or strongly acidic or alkaline environments) and are often accompanied by high energy consumption and environmental pollution issues. In contrast, enzymatic synthesis of amides has attracted widespread attention due to its mild conditions and environmental friendliness. To mine ancestral lipases with high activity and stability and investigate their enzymatic properties, thus achieving efficient enzymatic synthesis of amide bond-containing compounds. Ancestral lipases were screened based on a gene mining strategy employing ancestral sequence reconstruction (ASR), followed by characterization of their enzymatic properties and construction of an enzymatic reaction system for synthesis of the amide bond. Ancestral enzymes ASR-1 and ASR-7 with higher thermal stability were obtained. Substrate spectrum characterization revealed that ASR-1 preferentially catalyzed the synthesis of aromatic amides, while ASR-6 favored the synthesis of aliphatic amides. ASR-1 was purified via nickel-affinity chromatography and characterized for its enzymatic properties, showing an optimal reaction pH in Tris-HCl 7.5 and an optimal reaction temperature of 40 \u00b0C. The reaction conditions for amide synthesis were systematically optimized as 10 mg/mL wet cells, water content \u226410% (V/V), n-dodecane as solvent, 20 mmol/L amine substrate, and 10 mmol/L acyl donor. In addition, the enzyme exhibited good tolerance to nonpolar solvents, achieving an amide yield of 73.25%.

This study investigates the potential role of adenotonsillectomy in pediatric-onset multiple sclerosis (POMS) risk and relapse rate. POMS participants and controls were recruited from 16 pediatric MS clinics between 1 November 2011 and 1 July 2017. Clinical and demographic information, including history of adenotonsillectomy, EBV serostatus, and HLA-DRB1*15:01:01 status, were collected. Multivariable logistic regression assessed the association between adenotonsillectomy and MS risk. In addition, negative binomial regression offset by follow-up time was used to assess the relationship between adenotonsillectomy and relapse rate in POMS participants with available follow-up data. The case-control analysis included 359 POMS participants and 560 pediatric controls. Individuals with a history of adenotonsillectomy had a 63% increased odds of MS (adjusted odds ratio (OR)\u2009=\u20091.63, 95% confidence interval (CI)\u2009=\u20091.01-2.64, p\u2009=\u20090.046). Among the 239 POMS participants with available follow-up data, adenotonsillectomy was associated with a twofold increase in annualized relapse rate (adjusted incidence rate ratio (IRR)\u2009=\u20092.00, 95% CI\u2009=\u20091.15-3.48, p\u2009=\u20090.013). Prior adenotonsillectomy was associated with increased risk of MS and greater relapse rate in pediatric patients, suggesting a potential interplay between EBV, immune regulation, and MS pathogenesis.\n\nID: 42128511\nTitle: Fatigue after COVID-19 in occupationally exposed workers: prevalence, severity and associated risk factors in a cross-sectional analysis of a multicentre registry study.\nAbstract: As fatigue is among the most frequent manifestations of post-COVID syndrome (PCS), this study aimed to assess the prevalence and severity of cognitive and physical fatigue after occupational SARS-CoV-2 infection and to identify sociodemographic, clinical and occupational predictors of fatigue severity. Cross-sectional analysis of a multicentre prospective registry. Six German Social Accident Insurance hospitals distributed across Germany, providing standardised post-COVID assessments for individuals with persistent symptoms following occupational SARS-CoV-2 infection. Workers with confirmed SARS-CoV-2 infection recognised as an occupational disease or work-related accident who presented with persistent symptoms and were enrolled in a multicentre post-COVID registry. Cognitive and physical fatigue severity assessed using validated self-administered questionnaires (Fatigue Scale for Motor and Cognitive Functions, Modified Fatigue Impact Scale and W\u00fcrzburg Fatigue Inventory for Multiple Sclerosis). Clinical relevance was determined based on established cut-offs reported in the literature. Fatigue severity was operationalised using median splits of the respective subscales to identify factors associated with higher fatigue levels. Among 1511 registry cases, 628 participants had complete fatigue data. Median age was 54 years, 77% were female and most worked in nursing (43%) or educational/care professions (19%). Clinically relevant fatigue was highly prevalent: cognitive fatigue affected 78%-93% and physical fatigue 87%-98%. Both fatigue dimensions were positively correlated with older age, work incapacity and persistent symptom burden. In multivariate analyses, a higher number of acute symptoms was associated with lower odds of cognitive fatigue (adjusted OR 0.39, 95%\u2009CI 0.19 to 0.81), while physical fatigue remained associated with profession (adjusted OR 2.04, 95%\u2009CI 1.17 to 3.59). Sex, pre-existing conditions, hospitalisation and variant wave were not significant predictors in either model. Fatigue is a prevalent and disabling PCS-symptom among occupationally exposed workers. Distinct determinants of cognitive and physical fatigue emphasise the need for early recognition, targeted management and rehabilitation strategies to support recovery and work reintegration.\n\nID: 42125982\nTitle: Integrating Genetics and Environment to Find Causal Mechanisms for Multiple Sclerosis.\nAbstract: Genome-wide association studies (GWAS) have identified hundreds of risk loci for multiple sclerosis (MS), but we have limited knowledge of the mechanisms through which genetic variants mediate risk. Similarly, epidemiological studies implicate numerous environmental risk factors in MS risk, but these cannot identify specific causal mechanisms. We review our current knowledge of genetic mechanisms in MS, including the critical role of expression quantitative trait locus (eQTL) mapping in translating genetic risk loci into causal mechanisms. Molecular and functional context has emerged as an important missing component of these studies, and we discuss how environmental risk factors can be modelled in a quantitative genetic context to identify disease mechanisms. In parallel, we highlight recent advances in which quantitative genetic methods establish a causal role for low vitamin D and obesity in MS, and to dissect the mechanisms through which these operate. As genetic, transcriptional, and epigenetic studies continue to expand, further mechanistic insights for MS are likely to come from the integration of genetic and environmental data.\n\nID: 42061910\nTitle: Geographic distribution of mortality from systemic lupus erythematosus.\nAbstract: BackgroundSystemic lupus erythematous (SLE) shares many common epidemiologic features with other autoimmune diseases or diseases associated with an underlying Epstein-Barr virus (EBV) infection. It was hypothesized that the geographic variation of mortality from SLE would reveal a similar pattern as Hodgkin lymphoma (HL), multiple sclerosis (MS), Crohn's disease (CD), and ulcerative colitis (UC).MethodsUsing the vital statistics of 21 countries from 1951-2022, overall and age-specific death rates from the 5 diseases were calculated for each individual country. The death rates of different countries were compared using linear regression analysis.ResultsWhereas other autoimmune diseases or diseases associated with an underlying EBV infection, such as HL, MS, CD, and UC, showed remarkably similar geographic variations, the geographic distribution of SLE did not fit this overall pattern. High death rates from SLE were not clearly associated with developing versus developed countries, northern versus southern latitude, or any specific continent. However, similar geographic distributions of SLE were consistently found among consecutive age groups, ranging from 0-4 to 85+ years.ConclusionsThe similarities in the geographic distributions of death rates from HL, MS, CD, and UC suggest that these 4 diseases share a set of one or more common environmental risk factors. Other environmental risk factors besides EBV infection must contribute to the varying occurrence of SLE across the globe. These risk factors start exerting their influence at a very young age of less than 5\u00a0years.\n\nID: 41986183\nTitle: Non-infectious environmental risk factors of multiple sclerosis: Mechanisms and intervention windows for prevention.\nAbstract: The trajectory of multiple sclerosis (MS) is shaped by complex interactions between genetic susceptibility and environmental factors. This review examines modifiable non-infectious determinants across the life course and proposes integrated prevention strategies. Key factors include vitamin D deficiency, low UV exposure, smoking, adolescent obesity, air pollution, and chemical environmental exposures. Mendelian randomization studies support the causality of several determinants, particularly low vitamin D and high BMI. Adolescence emerges as a critical susceptibility window where the maturing immune system is uniquely sensitive to metabolic and environmental triggers. Among validated interventions, vitamin D supplementation stands out for its ability to reduce disease activity in early MS. Effective prevention requires both individual actions and structural public health policies, such as air quality regulations and urban \"walkability\". Future efforts should prioritize multimodal strategies targeting high-risk youths through the educational system (physical activity, weight management, and smoking prevention). These holistic approaches offer broad-spectrum benefits, reducing the burden of MS while preventing comorbidities, including cardiovascular, metabolic but also cancer.\n\nID: 41983136\nTitle: Vitamin D status, supplementation, and multiple sclerosis: a systematic review and meta-analysis.\nAbstract: Multiple sclerosis (MS) is a chronic immune-mediated neurodegenerative disorder of the central nervous system and a leading cause of disability among young adults. The disease exhibits considerable heterogeneity in clinical progression, with some patients experiencing more aggressive disease activity and a rapid decline in quality of life. Vitamin D plays a key role in immune regulation, and evidence suggests that its deficiency constitutes a significant environmental risk factor for immune-mediated conditions such as MS. While there are controversies regarding the role of serum 25(OH)D in MS as well as vitamin D3 supplements in controlling relapse and disability improvement during treatment. Therefore, our current meta-analysis aims to examine the relationship between serum 25(OH)D levels-and their modulation through supplementation-and multiple sclerosis. Comprehensive literature review was performed from conception to November 17, 2025, employing various online databases including PubMed, Cochrane Library, Web of Science, and EMBASE. The relevant studies about MS and serum 25-hydroxyvitamin D (25(OH)D) level or vitamin D3 supplementation. This meta-analysis incorporated 40 research examining the correlation between serum 25(OH)D levels and multiple sclerosis, as well as 22 studies investigating the effects of vitamin D3 supplementation on multiple sclerosis. 1) The 25(OH)D levels in patients with MS were significantly lower than those in healthy controls. In the analysis of disease subtypes, patients with relapsing-remitting MS (RRMS) had significantly higher 25(OH)D levels than those with secondary progressive MS (SPMS), but no significant difference was observed compared to patients with primary progressive MS (PPMS). Additionally, RRMS patients had significantly lower 25(OH)D levels during relapse than during remission. No significant seasonal fluctuation in 25(OH)D levels was observed in MS patients; 2) Multivariable-adjusted analysis comparing the highest versus lowest serum 25(OH)D categories revealed that higher serum 25(OH)D levels were associated with a lower risk of MS onset and lower disability scores (EDSS), but no significant association was found with disease activity. 3) In the intervention analysis, overall, vitamin D3 supplementation did not significantly reduce the annualized relapse rate (ARR) or improve EDSS scores. However, subgroup analysis indicated that high-dose vitamin D3 supplementation significantly reduced the ARR, whereas low-dose supplementation showed no\u00a0such effect. Multivariable-adjusted analysis further confirmed that vitamin D3 supplementation was significantly associated with a reduced risk of MS\u00a0relapse, and this benefit was similarly observed only in the high-dose supplementation group. This systematic analysis confirms that patients with MS exhibit significantly lower serum 25(OH)D levels compared to healthy controls, with notable reductions observed during clinical relapses. A clear gradient exists across disease subtypes, with RRMS patients showing higher levels than those with SPMS. An inverse correlation was demonstrated between serum 25(OH)D levels and both the risk and severity of MS. Critically, while high-dose vitamin D3 supplementation is associated with a reduced ARR and overall relapse risk, neither supplementation compared to placebo nor dosage comparison significantly affected relapse rates during the study period or final disability scores. These findings suggest a complex, dose-dependent role of vitamin D in modifying relapse risk without a clear impact on short-term disability progression in established MS. https://www.crd.york.ac.uk/PROSPERO/login, identifier CRD420251273119.\n\nID: 41956308\nTitle: Mechanistic insights into Nicotine-derived nitrosamine ketone (NNK) in multiple sclerosis via integrated systems analyses.\nAbstract: Multiple sclerosis (MS) is characterized by recurrent neuroinflammatory episodes that drive progressive neurodegeneration, with cigarette smoking recognized as a major environmental risk factor. Nicotine-derived nitrosamine ketone (NNK), a potent tobacco-specific nitrosamine, has been implicated in MS; however, its mechanistic contribution to disease pathogenesis remains poorly understood. Here, we applied an integrative multi-level approach to investigate the potential role of NNK in MS. Mendelian randomization (MR) analysis identified genetically predicted dipeptidyl peptidase-4 (DPP4) activity as being associated with MS susceptibility. Molecular docking further demonstrated feasible interactions between NNK and candidate proteins, including DPP4, providing theoretical plausibility for chemical-protein interactions. In experimental autoimmune encephalomyelitis (EAE) mice, systemic NNK exposure accelerated disease onset, aggravated neurological deficits, and enhanced immune cell infiltration and demyelination within the central nervous system (CNS), accompanied by increased DPP4 expression in inflamed regions. Consistent with these observations, in vitro NNK treatment impaired endothelial barrier integrity in bEnd.3 cells by reducing tight junction proteins (ZO-1, Claudin-5, and Occludin) and upregulating adhesion molecules (VCAM-1 and ICAM-1). NNK exposure also triggered inflammatory activation in BV2 microglia, resulting in elevated expression of TNF-\u03b1, IL-1\u03b2, and IL-6. Importantly, DPP4 silencing partially restored endothelial junctional integrity and attenuated pro-adhesive signaling in endothelial cells while reducing inflammatory cytokine expression in microglia, suggesting that DPP4 is functionally involved in NNK-induced neurovascular inflammation. Together, these findings suggest that NNK exposure may modulate neuroinflammatory processes relevant to MS through blood-brain barrier (BBB) disruption and microglial activation, with DPP4 potentially being involved in this process. This study provides mechanistic insights into how smoking-associated toxins may influence MS progression and highlights DPP4-related pathways as potential targets for therapeutic investigation.\n\nID: 41889330\nTitle: Interplay between genetic and environmental risk factors in multiple sclerosis: what have we learned?\nAbstract: Genome-wide association studies have identified >230 genetic variants associated with susceptibility to multiple sclerosis and one genome-wide significant variant associated with progression of multiple sclerosis. Environmental risk factors, such as vitamin D deficiency and obesity, have also been implicated in multiple sclerosis pathogenesis. Statistical approaches building on these genetic data, such as Mendelian randomization and co-localization, have established putative causal links between environmental risk factors and multiple sclerosis risk, most notably for vitamin D and body mass index. However, studies have thus far revealed limited statistically significant interactions between host genetics and environmental factors beyond the major histocompatibility complex. Epigenetics (the study of non-nucleotide alterations to DNA, such as DNA methylation or histone acetylation) might provide a mechanistic framework for understanding how environmental and genetic factors interact in multiple sclerosis. Environmental factors, such as Epstein-Barr virus infection, vitamin D deficiency and smoking, are associated with epigenetic modifications at key multiple sclerosis-related genomic loci, altering the expression of multiple sclerosis risk genes in a cell type-specific manner. Transcriptomics have identified significant pathways via which genetic risk is realized, potentially providing targets for intervention. This review synthesizes current evidence on gene-environment interactions in the context of multiple sclerosis genome-wide association study findings, evaluates the strengths and limitations of various study methodologies, and discusses the challenges in elucidating the interplay between genetics and environmental factors. We propose potential strategies for future research to advance our understanding of the biological mechanisms underlying multiple sclerosis susceptibility in at-risk individuals.\n\nID: 41873126\nTitle: Epstein-Barr Virus Transformed B Cells From Systemic Lupus Erythematosus and Multiple Sclerosis Patients Differ in EBV Lytic and Latency Marker Expression.\nAbstract: Epstein-Barr virus (EBV) is an important environmental risk factor in the development of several autoimmune conditions, with the mechanisms still to be fully elucidated. EBV primarily infects memory B cells, transitioning between lytic (active) and latent (dormant) phases of infection. Our group has previously proposed two molecular mechanisms linking EBV pathogenesis to autoimmunity: one indicates that EBV lytic switching contributes to systemic lupus erythematosus (SLE) pathogenesis, while another posits that latency III is more crucial in the development of multiple sclerosis (MS). In this study, we tested the proposed molecular model using a cohort of EBV-transformed lymphoblastoid cell lines derived from individuals with either SLE, MS or healthy controls. Measuring the expression levels of a panel of EBV genes, representing the different phases of the EBV lifecycle, we found compelling proof-of-concept evidence validating our proposed model. This discovery highlights promising signatures for further investigation, where the same approach can be explored across other EBV-associated immune conditions, deepening our understanding of the virus's lifecycle dysregulation in autoimmunity etiology and ultimately aiding in the design of new treatments.\n\nID: 41836011\nTitle: The impact of nutritional, environmental, and lifestyle factors on neurological disorders: therapeutic implications and mechanistic insights.\nAbstract: Neurological disorders like Alzheimer's, Parkinson's, multiple sclerosis, and primary psychiatric conditions are complex, arising from a mix of genetic and modifiable risks. Growing evidence indicates that nutrition, environment, and lifestyle significantly influence disease development, progression, and treatment response. Nutrients such as vitamins, minerals, omega-3 fatty acids, and polyphenols affect neuroinflammation, oxidative stress, mitochondrial health, and neurotransmitter function. Dietary patterns like the Mediterranean and ketogenic diets offer protective benefits in clinical and experimental contexts. Meanwhile, environmental neurotoxicants-air pollution, heavy metals, pesticides, and endocrine disruptors contribute to neurodegeneration via oxidative damage, synaptic impairment, and epigenetic alterations. Lifestyle factors, such as physical activity, sleep, stress, and substance use, affect brain plasticity, neurogenesis, and metabolic health, thereby influencing disease progression over time. These factors often share common pathways such as oxidative stress, inflammation, vascular injury, mitochondrial dysfunction, and protein misfolding, underscoring the need for a comprehensive prevention and treatment strategy. Emerging therapies now incorporate personalized nutrition, lifestyle changes, and environmental risk mitigation alongside traditional drugs, supported by advances in multi-omics, digital health, and systems biology. Public health efforts to reduce neurotoxic exposure and encourage healthy habits further strengthen these approaches. This review summarizes existing mechanistic and clinical knowledge, with a focus on the potential of nutritional, environmental, and lifestyle interventions in neurological diseases. It also outlines the future research required to enhance precision neurology and strategies for brain health prevention.\n\nID: 41824926\nTitle: Occupational Exposure to Industrial Dust and Rates of Multiple Sclerosis.\nAbstract: Exposure to lung irritants such as smoking and organic solvents has been associated with increased risk of multiple sclerosis (MS), particularly among genetically susceptible individuals. The aim of this study was to investigate the association between occupational exposure to industrial dust and MS and to assess potential interactions with smoking and HLA-DRB1*15:01. We conducted a Swedish population-based case-control study. Patients with incident MS age 16-70 years were consecutively identified by neurologists at 40 clinics (2005-2015). Eligibility criteria for participants were age 16-70 years, residence in Sweden, and a neurologist-confirmed diagnosis of MS according to the McDonald criteria. Controls without MS were randomly sampled from the national population register using density sampling and frequency-matched to cases on age, sex, and residential area. Occupational dust exposure was assessed using questionnaire data. Logistic regression was used to estimate odds ratios (ORs) and 95% CIs. Additive interactions between dust exposure and smoking and between dust exposure and HLA-DRB1*15:01 were assessed by calculating the attributable proportion (AP) due to interaction. An AP >0 is considered evidence of interaction. The analytic sample included 2,070 participants and 2,899 controls. The mean age at index was 34.4 years for participants and 35.4 years for controls. Women comprised 72.5% of participants and 75.1% of controls. Industrial dust exposure was associated with increased rate of MS (OR 1.30, 95% CI 1.05-1.63), with a dose-response relationship with duration (OR per 1-year exposure 1.03, 95% CI 1.00-1.06). Evidence of additive interactions was observed between dust exposure and smoking (AP 0.32, 95% CI 0.03-0.62) and between dust exposure and HLA-DRB1*15:01 (AP 0.25, 95% CI 0.002-0.52). Participants who smoked, were exposed to dust, and carried the HLA-DRB1*15:01 allele had an 11-fold increased rate of MS (OR 11.1, 95% CI 5.7-21.9), compared with those without any of these risk factors. Occupational dust exposure was associated with increased rate of MS, particularly in combination with smoking and HLA-DRB1*15:01, suggesting joint effects of occupational, environmental, and genetic risk factors. The reliance on self-reported occupational histories and potential residual confounding are important limitations. Further studies are warranted to clarify underlying mechanisms and to inform preventive strategies.\n\nID: 42615640\nTitle: Bis(styryl)benzene Probes for Targeting Early-Stage Amyloid-\u03b2 Aggregates in Alzheimer's Disease.\nAbstract: With the recent FDA approval of antibody-based therapeutics for Alzheimer's disease (AD), the need for diagnostic tools capable of detecting the disease at the earliest stages has become increasingly urgent. Although small molecules offer advantages in terms of production, stability, and accessibility, no imaging agent currently enables reliable detection of early-stage aggregates of the amyloid-\u03b2 (A\u03b2) peptide, among the earliest biomarkers in AD progression. Herein, we report a series of bis(styryl)benzene (BSB) probes derived from the methoxy-X04 scaffold and a systematic structure-activity investigation examining how targeted molecular modifications, including hydroxyl positioning, (Me)HN or (Me)2N substitution, and incorporation of a 1,4-dimethyl-1,4,7-triazacyclononane (tacn) moiety, modulate A\u03b2 binding, cytotoxicity, and brain uptake. These methoxy-X04 analogues retain A\u03b2 affinity while exhibiting markedly improved cytotoxicity profiles and logD values consistent with in vivo applicability. Amyloid-\u03b2 binding was evaluated using age-dependent in situ staining of 5xFAD mouse brain sections, supported by in vitro fluorescence-based oligomer and fibril assays and in silico analyses that reveal tunable selectivity toward early versus late A\u03b2 aggregates. In vivo brain uptake studies of BSB5 and Me2tacnBSB5 further support the utility of these probes as modular A\u03b2-targeting fragments for the development of early-stage AD imaging agents.\n\nID: 42595356\nTitle: Environmental hazards and climate change: Unmasking Parkinson's hidden enemies.\nAbstract: Parkinson's disease (PD) is a multifactorial neurodegenerative disorder shaped by interactions between genetic susceptibility, environmental exposures, and broader ecological change. Although pesticides, industrial solvents, heavy metals, and air pollutants have long been implicated as potentially modifiable PD risk factors, climate change is now reshaping and amplifying these hazards through rising temperatures, worsening air quality, increased pesticide demand, extreme weather events, and wildfire-related particulate matter.This narrative review moves beyond a conventional exposure-based summary by integrating environmental toxicology, climate science, epidemiology, and mechanistic neuroscience to reframe PD risk within the context of planetary health. We summarize evidence linking major environmental hazards to PD pathogenesis, emphasizing convergent mechanisms such as oxidative stress, mitochondrial dysfunction, impaired proteostasis, neuroinflammation, blood-brain barrier disruption, and \u03b1-synuclein aggregation. We further discuss how climate-related changes may intensify these pathways and disproportionately affect vulnerable populations, including agricultural workers, older adults, socioeconomically disadvantaged communities, and individuals living in rapidly industrializing or climate-sensitive regions. Importantly, we highlight clinical and public health implications by proposing that structured environmental and occupational exposure assessment should be incorporated into PD risk evaluation, early recognition, preventive counseling, and research design. We also discuss exposure reduction, workplace protection, environmental monitoring, and regulatory policy as prevention-oriented strategies. By positioning environmental hazards and climate change as interconnected, underrecognized, and potentially modifiable contributors to PD, this review provides a framework for clinicians, researchers, and policymakers seeking to reduce the future global burden of neurodegenerative disease. Parkinson's disease (PD) is a common neurodegenerative disorder that develops over time and affects movement, balance, and many daily activities. While genes play a role, most cases of PD do not arise solely from genetics. Growing evidence shows that environmental exposures, such as pesticides, industrial chemicals, heavy metals, and air pollution, can increase the risk of developing PD. Importantly, many of these exposures can be reduced or prevented. Climate change is worsening these environmental risks. Higher temperatures, poorer air quality, increased pesticide use, and more frequent wildfires are increasing human exposure to harmful pollutants worldwide. Together, these changes may increase the number of people affected by PD, especially in communities already facing environmental or social disadvantages. This review explains how environmental toxins can damage brain cells through shared biological processes, including oxidative stress, inflammation, and abnormal protein buildup. It also highlights regions and populations that may be more vulnerable to these risks. From a healthcare perspective, understanding a person's environmental and work-related exposures can help identify those at higher risk, support earlier recognition of PD, and guide prevention advice. Overall, environmental toxins and climate change are underrecognized yet actionable determinants of PD. Increasing awareness, improving environmental protections, and integrating exposure history into clinical care are key steps toward reducing the future global burden of PD.\n\nID: 42405595\nTitle: Uric Acid Released from Poly (Lactic-co-Glycolic Acid) Nanoparticles Mitigates Glutamate-Induced Excitotoxicity of Spinal Cord Neurons.\nAbstract: Spinal cord injury (SCI) is often compounded by secondary damage caused by glutamate-induced excitotoxicity (GIE), where excessive glutamate release results in neuronal damage by overstimulation of glutamate receptors. This process leads to mitochondrial dysfunction, oxidative stress, and neuronal death. Uric acid (UA) has been identified as a potential neuroprotective molecule due to its antioxidant properties, but its limited solubility poses challenges for clinical use. To address this issue, we encapsulated UA in poly (lactic-co-glycolic acid) nanoparticles (UA-NPs) using a modified double emulsion technique to enhance stability and delivery of UA. Spinal cord cultures were subjected to GIE, followed by treatment with UA-NPs or empty nanoparticles. Neuronal survival was assessed with immunocytochemistry for the neuronal marker microtubule-associated protein 2 (MAP2), which revealed that treatment with UA-NPs resulted in significantly higher cell survival compared to cultures treated with empty nanoparticles. These findings suggest that UA-NPs provide neuroprotection to spinal cord neurons in\u00a0vitro and may serve as a promising localized drug delivery system for SCI treatment, offering a targeted approach to mitigate secondary injury. Spinal cord injuries can cause long-term damage not only from the initial injury but also from secondary injury processes that worsen the condition over time. One of these processes involves glutamate, an important neurotransmitter normally present in cells. However, when released in excess, glutamate can overstimulate nearby neurons and lead to damage and death of nerve cells. This process can harm essential cell functions, increase stress within cells, and reduce their ability to survive. Uric acid is a natural substance in the body that can help protect cells because of its antioxidant properties. However, it does not dissolve well in water-based solvents, including blood, making it difficult to use as a treatment. To overcome this problem, we packaged uric acid into tiny particles called nanoparticles, which improve its stability and delivery to cells. In this study, we tested our uric acid-loaded nanoparticles on spinal cord cells after exposing them to harmful conditions similar to those seen after injury. We found that cells treated with these nanoparticles survived better than those treated with empty particles. These results suggest that delivering uric acid using nanoparticles may help protect nerve cells after spinal cord injury. This approach could lead to more effective treatments that target and reduce further damage after the initial injury.\n\nID: 42386299\nTitle: Parkinson-PEST: protocol for a case-control study on environmental risk factors and Parkinson's disease.\nAbstract: Growing evidence suggests that a part of the burden of Parkinson's disease (PD) can be explained by exposure to environmental factors, including pesticides, heavy metals, solvents, and air pollution. However, several questions remain unanswered, pertaining to the associations with PD of environmental factors that are still in use today; the added risks of co-exposure to multiple environmental factors and gene-environment interactions. Additional questions remain on the relevant time window, duration, and level of environmental exposures in relation to PD risk. Furthermore, it is unclear whether these exposures are associated with clinical progression of PD. PD-PEST (Parkinson's Disease-Preventing Emergence of Symptoms by environmental Toxicants) is a nationwide hospital-based case-control study conducted in the Netherlands. The study population consists of 1500 persons with a recent PD diagnosis and 3000 age- and sex-matched controls. Participants will be recruited from four regions across the Netherlands to ensure a representative geographical distribution in terms of urbanisation, industry, and agricultural activity. Cases must have a PD diagnosis, established by a neurologist in the Netherlands according to standard diagnostic criteria. Controls are outpatients with a different neurological condition that is unlikely to be associated with the environmental factors of interest or the risk of PD. We will collect detailed information on historical and current environmental exposures at an individual level. This includes occupational and residential histories (via questionnaires and nationwide registries) and measurements (blood, saliva, faeces, hair, and via silicone wristbands). Based on these multimodal data, we will estimate participants' individual lifetime exposure to environmental factors. Then, we will examine the associations between these exposures and the risk of PD. In addition, we will assess longitudinal associations between exposures and clinical progression of individuals with PD over 36 months. Analyses will be adjusted for possible confounders and multiple hypothesis testing. The PD-PEST study aims to overcome the limitations of previous studies by examining a large, representative study population, incorporating detailed information on clinical PD diagnosis, conducting extensive assessments of historical and current environmental risk factors and collecting detailed information on possible confounders. The results are expected to enhance our understanding of the role of environmental factors in the aetiology of PD and inform preventive strategies. The Medical Ethical Committee Oost-Nederland approved this study (NL86526.091.24). Informed consent will be obtained from each participant prior to participation in any of the study procedures. Findings of this study will be disseminated through publications, conferences, stakeholder briefings, and tailored communication materials for participants and the wider Parkinson community.

Herein, we report in vivo PK studies of the widely used amyloid probe methoxy-X04 (MeX04) in transgenic 5xFAD and wild-type (WT) mice. In plasma, MeX04 shows comparable exposure between 5xFAD and WT mice, indicating no major genotype-dependent differences in systemic clearance. In contrast, brain exposure was markedly increased in 5xFAD mice, with higher brain Cmax and AUC parameters and slower washout, consistent with A\u03b2-dependent sequestration and retention in the AD brain tissue. Notably, fluorescence microscopy revealed that the fluorescence intensity of amyloid plaque-bound MeX04 closely mirrored the total brain concentration, and we employed ex vivo fluorescence intensity quantification to evaluate the PK of a related bis(styryl)benzene compound, LS-4, which is proposed to exhibit increased affinity for soluble A\u03b2 aggregates. We then performed age-dependent ex vivo staining of compound-bound A\u03b2 aggregates in 5xFAD brains, and LS-4 exhibits appreciable amyloid-bound fluorescence intensity in younger 5xFAD mice, consistent with its higher affinity for A\u03b2 oligomers, whereas MeX04 exhibited stronger fluorescence intensity in older mice. Consequently, we propose an efficient approach to track temporal changes in the PK of A\u03b2-binding compounds by ex vivo evaluation of their amyloid-bound fluorescence intensity, providing a rapid assessment of the general PK trends of newly developed amyloid-binding probes.\n\nID: 41886018\nTitle: n-Hexane-Toxic Neuropathy Presenting with Cauda Equina Inflammation.\nAbstract: BACKGROUND: Habitual exposure to n-hexane can cause polyneuropathy through axonal degeneration and secondary demyelination. To our knowledge, n-hexane-toxic neuropathy presenting with a cauda equina-like syndrome has not previously been reported. CASE PRESENTATION: A 55-year-old man developed sensory and motor polyneuropathy over a 3-month period, with nerve conduction studies indicating demyelination. Initial treatment for suspected chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) with steroids and plasma exchange was ineffective, leading to worsening symptoms. The patient and his colleagues were found to have been habitually exposed to n-hexane in their printing work, and a sural nerve biopsy revealed the pathological findings typical of n-hexane-toxic neuropathy. Notably, cauda equina inflammation was observed on MRI and in the cerebrospinal fluid. Following intravenous immunoglobulin therapy, both neurological symptoms and findings from nerve conduction studies, MRI, and cerebrospinal fluid analysis gradually improved, eventually leading the absence of impairment in activities of daily living. CONCLUSION: In cases of polyneuropathy accompanied by inflammation of the cauda equina, and if exposure to n-hexane cannot be ruled out, sural nerve biopsy could be considered to assess for n-hexane-toxic neuropathy.\n\nID: 41819809\nTitle: Occupational exposure to chlorinated solvents and lung cancer: results of the SYNERGY case-control study.\nAbstract: The association between occupational exposure to chlorinated solvents and lung cancer remains inconclusive. This study investigated this relationship using data from the internationally pooled SYNERGY study. Data from 14 case-control studies conducted in 13 European countries and Canada were pooled, including 28\u2009048 participants (12\u2009329 cases and 15\u2009719 controls). Lifetime occupational exposure to chlorinated solvents was assessed using the ALOHA+job-exposure matrix. ORs and 95% CIs were estimated using unconditional logistic regression, adjusted for study centre, age, sex, smoking (pack-years and cessation), cumulative exposure to five occupational lung carcinogens (asbestos, hexavalent chromium, polycyclic aromatic hydrocarbons, respirable crystalline silica and diesel engine exhaust), cumulative benzene exposure and employment in high-risk occupations ('List A' jobs). Associations were estimated across categories of exposure levels, durations and analyses stratified by smoking status and lung cancer subtypes. We found no evidence of an association between ever exposure to chlorinated solvents and lung cancer risk (OR 1.03; 95%\u2009CI 0.96 to 1.10). Among exposed individuals, a positive trend with cumulative exposure was observed (p=0.031), but not when non-exposed individuals were included (p=0.173). Positive trends were found with exposure duration (p=0.005 for exposed; p=0.048 overall); risks were modestly elevated (OR 1.11) in those exposed for 20 or more years. No increased risk was observed across smoking strata or lung cancer subtypes. This pooled analysis provides limited evidence of an association between occupational exposure to chlorinated solvents and lung cancer, though exposure-response trends were noted among exposed individuals.\n\nID: 41687739\nTitle: Protective effects of sodium benzoate against toluene-induced reward enhancement, behavioral disturbances, and impaired synaptic plasticity in mice.\nAbstract: Toluene is one of the most commonly abused solvents. Inhibition of N-methyl-D-aspartate receptor (NMDAR) has been linked to the rewarding and behavioral effects of toluene. One of the avenues to enhance NMDAR function is to increase the levels of D-serine via inhibiting D-amino acids oxidase (DAAO) activity. The present study determined whether sodium benzoate, a DAAO inhibitor, could counteract the toluene-induced brain stimulation reward enhancement, behavioral disturbances, and hippocampal synaptic dysfunction after acute toluene exposure. Male mice received various doses of sodium benzoate before toluene exposure for assessment of intracranial self-stimulation (ICSS) thresholds, rotarod test, novel object recognition task, social interaction test, and long-term potentiation (LTP) and long-term depression (LTD) of hippocampal synaptic transmission. Sodium benzoate prevented the lowering of ICSS thresholds, motor incoordination, social withdrawal, object recognition memory deficit, and impaired LTP and LTD induced by toluene. These results indicate that sodium benzoate could ameliorate toluene-induced facilitation of brain reward function, behavioral disturbances, and synaptic plasticity impairment, suggesting that sodium benzoate may be a promising compound against acute toluene intoxication caused by unintentional or deliberate inhalation.\n\nID: 41683329\nTitle: Serotonin, Kynurenine, and Indole Pathways of Tryptophan Metabolism in Humans in Health and Disease.\nAbstract: Tryptophan (TRP) is a proteinogenic and nutritionally essential amino acid involved in the formation of numerous bioactive substances. A crucial role in the TRP molecule is played by indole, a bicyclic ring formed by benzene and pyrrole, which confers hydrophobic and antioxidant properties and the ability to act as a ligand for aryl hydrocarbon and pregnane X receptors. The first parts of the article examine sources, nutritional requirements, and three pathways of TRP catabolism. Physiologically, ~5% of dietary TRP is catabolized through the pathway forming serotonin and melatonin in the brain and enterochromaffin cells of the gut, ~85% through the pathway resulting in the formation of nicotinamide nucleotides and kynurenine and its derivatives in the liver and immune cells, and ~10% in gut microbiota to indole derivatives. Alterations of individual TRP catabolism pathways in aging, alcoholism, inflammatory bowel disease, metabolic syndrome, renal insufficiency, liver cirrhosis, cancer, and nervous diseases, e.g., depression, Alzheimer's and Parkinson's diseases, multiple sclerosis, and schizophrenia, are examined in the central section. The final sections are devoted to the benefits and adverse effects of TRP supplementation, the therapeutic use of various TRP metabolites, and the pharmacological targeting of enzymes, transporters, and receptors involved in TRP catabolism. It is concluded that all pathways of TRP catabolism are altered across a broad spectrum of human illnesses, and further investigation is needed to understand their role in disease pathogenesis better. The goal for clinical research is to explore options for TRP-targeted therapies and their integration into new therapeutic strategies.\n\nID: 41576772\nTitle: Synergistic disruption of blood-brain barrier and neuroimmune homeostasis by sleep-related environmental pollutants drives sleep disorders: an integrated computational and experimental study.\nAbstract: Environmental pollutants are increasingly linked to sleep disorders (SD), affecting 27% of people globally, yet their synergistic effects remain understudied. Network toxicology identified 252 shared targets between sleep-related environmental pollutants (SREPs: NO2, formaldehyde, benzene) and SD. PPI network and diagnostic model identified four hub genes (HSP90AA1, RELA, PTGS2, MMP9) with moderate-to-high predictive value (AUC: 0.708-0.979). Immune infiltration analysis showing elevated T cells and reduced astrocytes and neurons in patients with SD. Molecular simulations confirmed stable SREP-hub protein binding, with benzene exhibiting the highest affinity. Crucially, mixed SREPs exposure induced more severe toxicity than individual pollutants, demonstrating true synergistic disruption. In vivo, SREPs metabolites disrupted sleep architecture, impaired the blood-brain barrier (BBB), and induced neurobehavioral deficits. In vitro studies using brain endothelial cells (BMVECs) revealed that SREPs directly increase permeability, suppress tight junctions, and activate a pro-inflammatory cascade involving NF-\u03baB signaling, enhanced MMP9 activity, and prostaglandin E2 synthesis. Curcumin intervention effectively counteracted these effects, restoring BBB integrity, normalizing sleep patterns, and suppressing hub gene expression and neuroinflammation in vivo and in vitro by targeting the identified hub gene network. Our integrated computational-experimental strategy establishes a novel \"pollutant-BBB-neuroimmune-sleep\" axis, providing a mechanistic framework for assessing cumulative environmental risks and advancing targeted interventions.\n\nID: 41511719\nTitle: Bone mesenchymal stem cells attenuate axonopathy in spinal cord of rats exposed to 2,5-hexanedione via NGF-dependent and -independent pathways.\nAbstract: N-hexane is a widely used aliphatic hydrocarbon solvent that can cause central-peripheral neuropathy. Compared to peripheral nerve tissue, spinal nerve tissue is more vulnerable and typically non-regenerable. However, no effective treatments are currently available. Stem cells are attractive therapeutic cells because of their extensive self-renewal and pluripotent differentiation abilities. Accordingly, numerous studies are focused on their restorative potential. In the present study, we investigated the effects and mechanisms of stem cell therapy on spinal nerves damaged by 2,5-HD (a proximate toxic metabolite of n-hexane). Our results showed that spinal axonopathy induced by 2,5-HD was alleviated by bone mesenchymal stem cell (BMSC) transplantation. Further, by examining the expression of molecules associated with axonal outgrowth, NGF signaling was found to be involved in the regeneration of spinal axons. Moreover, intervention experiments showed that PTEN was also an essential component of BMSC therapy. Conclusively, our data suggested that BMSC transplantation can alleviate spinal injury induced by 2,5-HD through AKT/mTOR/CREB by NGF-dependent and -independent pathways.\n\nID: 41485273\nTitle: Pyrazole carboxylic acid borneol esters: Novel neuroprotective agents with rapid, efficient brain penetration for the treatment of ischemic stroke.\nAbstract: Ischemic stroke (IS) is an acute cerebrovascular condition marked by a high incidence, disability rate, and mortality. Edaravone and Dexborneol Concentrated Injection Solution (EDB) has been approved to improve neurological symptoms, daily living activities, and functional impairments resulting from acute IS. Our previous studies showed that replacing the benzene ring of Edaravone (Eda) with pyridine enhances its free radical scavenging capacity. In this study, we further oxidized the methyl group of Eda to a carboxylic acid and used a structural hybridization strategy with (+)-borneol to synthesize a series of pyrazole carboxylic acid borneol esters. We evaluated the free radical scavenging ability of the synthesized compounds, identifying candidate compound B16, which outperforms Eda. The IC50 values of B16 against DPPH and ABTS free radicals were 7.98\u00a0\u03bcM and 5.50\u00a0\u03bcM, respectively. Cellular studies have shown that B16 maintains intracellular redox homeostasis and mitochondrial function, while also alleviating DNA damage in an oxygen - glucose deprivation/reperfusion (OGD/R)-induced SH-SY5Y cell model, demonstrating excellent neuroprotective effects. Further in vivo pharmacodynamic studies have demonstrated that B16 not only restores cerebral blood flow and significantly reduces infarct size in middle cerebral artery occlusion/reperfusion (MCAO/R) mice, but also improves sensory and motor functions, and promotes the recovery of neuronal cells and the blood-brain barrier (BBB) in the brain. Notably, B16 exhibits excellent BBB permeability and shows promising brain exposure levels within 5\u00a0min of administration. Preliminary biosafety studies indicated no obvious organ toxicity from B16. Collectively, the pyrazole carboxylic acid borneol ester compound B16 holds promise as a candidate for anti-IS treatment.\n\nID: 41459648\nTitle: Biophysical basis for brain folding and misfolding patterns in ferrets and humans.\nAbstract: A mechanistic understanding of neurodevelopment requires us to follow the multiscale processes that connect molecular genetic processes to macroscopic cerebral cortical formations and thence to neurological function. Using MRI of the brain of the ferret, a model organism for studying cortical morphogenesis, we create in vitro physical gel models and in silico numerical simulations of normal brain gyrification. Using observations of genetically manipulated animal models, we identify cerebral cortical thickness and cortical expansion rate as the primary drivers of dysmorphogenesis and demonstrate that in silico models allow us to examine the causes of aberrations in morphology and developmental processes at various stages of cortical ontogenesis. Finally, we explain analogous cortical malformations in human brains, with comparisons with human phenotypes induced by the same genetic defects, providing a unified perspective on brain morphogenesis that is driven proximally by genetic causes and affected mechanically via variations in the geometry of the brain and differential growth of the cortex. The wrinkled and folded surface of the human brain is both iconic and familiar. These folds allow a large cortical surface area to fit inside the skull and are essential for healthy brain function. The folds form during development when the brain\u2019s outer layer \u2013 the cerebral cortex \u2013 grows faster than the tissue beneath it, causing the surface to buckle. When this process is disrupted, the brain can develop abnormal folding patterns known as malformations of cortical development. In humans, these conditions are associated with epilepsy, intellectual disability and developmental delay. Studying how such malformations arise is challenging because human brain folding occurs before birth. To address this, researchers use animal models. The ferret is particularly valuable because its brain develops folds similar to those in humans, and many genes linked to human cortical malformations produce comparable folding defects in ferrets. Choi et al. wanted to find out whether the wide range of brain folding abnormalities seen in ferrets and their homologs in humans could be explained by changes in just a few physical properties of the developing brain. Specifically, they tested whether mutations linked to human cortical malformations alter the thickness or growth rate of the cortex. This question is important because different genetic syndromes often result in surprisingly similar brain shapes. By combining brain imaging, computer simulations, and physical gel models of brains that fold when their surfaces absorb solvents and swell (similar to how fingertips swell and wrinkle when wetted for a while), Choi et al. showed that normal brain folding in ferrets can be explained by mechanical forces generated during cortical growth. Both physical experiments with gels and computer simulations of brains with varying cortical thickness or growth rates reproduced folding patterns seen in both healthy and genetically altered ferret brains and their human homologs. Local thinning of the cortex generated many small, tightly packed folds, resembling polymicrogyria, a condition linked to mutations such as those affecting the gene SCN3A, which encodes instructions to form a sodium channel. Reducing overall growth produced smaller, less folded brains similar to microcephaly, which is associated with genes such as ASPM. In contrast, weaker folding with shallow grooves \u2013 characteristic of lissencephaly \u2013 emerged when growth was reduced and cortical thickness increased, as seen with disruptions to genes such as TMEM161B. These results suggest that diverse human genetic disorders converge on common physical mechanisms that shape the brain. The work of c provides a unifying framework linking specific genes to brain shape through physical growth processes. The ferret provides a useful model organism with direct implications for human brain development and misfolding. In the future, it could help researchers interpret human brain scans and understand why different genetic disorders lead to similar malformations. However, before such insights can inform clinical practice, the models will need to incorporate additional biological detail and examine how altered folding affects brain function. More broadly, the paper also raises the question of how variations in brain folding patterns arise in non-human brains, which is the subject of a related study.\n\nID: 41408540\nTitle: Benzene and Pituitary-Thyroid Axis in Workers Exposed to Urban Pollution.\nAbstract: The aim of this study is to verify if outdoor workers' exposure to low dose of benzene in urban air may affect thyroid hormone levels. The study was conducted on a total sample of 334 subjects. Benzene's environmental monitoring has been performed through personal dosimeters, whereas, for the biological monitoring, we have measured the concentration of blood benzene, trans,trans-muconic acid (t,t-MA) urinary, and S-phenylmercapturic acid (S-PMA) urinary on thyroid hormones. The statistical analysis was performed. Statistic test shows that there is a negative correlation between blood benzene levels, t,t-MA urinary, FT3, and FT4; there is a positive correlation between blood benzene, t,t-MA urinary, and TSH. Occupational exposure to low dose of benzene in urban pollution can affect thyroid hormone levels in occupationally exposed workers.\n\nID: 41392123\nTitle: Inhalation of 1-bromopropane alters hippocampal expression of pathways related to immune system/inflammation and insulin signaling in experimental rats.\nAbstract: 1-Bromopropane, an alternative to ozone-depleting solvents, exhibits neurotoxicity in humans and rats. The aim of the present study was to identify the genes or signaling pathways involved in the neurotoxicity and hepatotoxicity of 1-bomopropane in two inbred strains of rats. F344 rats and WNA/NUM rats were exposed to 1-bromopropane or filtered air by inhalation for either a single 8-hour session, or 8 h daily for 4 weeks. Motor nerve conduction velocity and distal latency were measured in the tail. At the end of the experiment, the animals were decapitated, and the hippocampus, liver, and blood were collected. Exposure to 1-bromopropane for 4 weeks increased distal latency in the tail nerve significantly in F344 and marginally in WNA/NUM. It also increased total and direct bilirubin in both rat strains. Eight-hour exposure increased metallothionein 2A, metallothionein 1 and NAD(P)H quinone dehydrogenase 1 expression in the liver of both rat strains, whereas 4-week exposure upregulated glutathione S-transferase alpha 3 and CD36 molecule in the liver of both strains. KEGG analysis showed that 8-hr 1-bromopropane upregulated pathways of apoptosis, NOD-like receptor signaling and colorectal cancer, in both the hippocampus and liver, whereas 4-week exposure upregulated NOD-like receptor signaling pathway both in the hippocampus and liver of the two rat strains. Insulin signaling pathway was upregulated persistently in the hippocampus of the two rat strains. Our results suggest the involvement of immune system/inflammation-related pathway in the neuro- and hepato-toxicity of 1-bromopropane and the involvement of insulin signaling pathway in the neurotoxicity of 1-brromopropane.\n\nID: 41206641\nTitle: Lifetime occupational and para-occupational exposure to organic solvents and testicular germ cell tumor risk: a French case-control study-TESTIS.\nAbstract: Despite an incidence increase in recent decades, the etiology of testicular germ cell tumors (TGCT) remains poorly understood. The hypothesis of a two-stage development, combining initial alteration in utero followed by malignant transformation later in life, has been suggested. This study examined the association between cumulative lifetime occupational and para-occupational solvent exposure and TGCT risk. The French multicenter case-control study TESTIS included 454 cases and 670 controls. Participants provided information on their occupational history; participants' mothers (N\u2009=\u2009547) provided information on their own and the father's occupational history. Solvent exposure was assessed by using the Matg\u00e9n\u00e9 job-exposure matrices. The influence of the parental and subject's occupational exposures over the lifetime and at different periods (i.e. fetal life/infancy; childhood; adolescence; subject's exposure) on TGCT was examined. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated by using conditional logistic regression models. An OR for TGCT of 1.03 (95% CI 0.59-1.79) was found for the lifetime solvent exposure. When each period was examined individually, the results showed an increased TGCT risk in adult males who were occupationally exposed to trichloroethylene (OR\u2009=\u20093.09; 95% CI 1.25-7.65); fuels and petroleum-based solvents (OR\u2009=\u20091.91; 95% CI 1.21-3.02); diesel, kerosene, and fuel oil (OR\u2009=\u20092.26; 95% CI 1.16-4.41); and ketones and esters (OR\u2009=\u20091.66; 95% CI 1.02-2.71), and suggested a positive association with solvent exposure during adolescence (OR\u2009=\u20091.77; 95% CI 0.95-3.31). Overall, this study did not suggest a substantial role of cumulative lifetime solvent exposure and TGCT risk. The results showed an increased TGCT risk associated with solvent exposure during adulthood. Indirect exposure to certain solvents during adolescence might also promote TGCT development.\n\nID: 41161784\nTitle: Oligodendroglia Generate Vascular Mural Cells and Neurons in the Adult Mouse Brain.\nAbstract: Oligodendroglia encompass oligodendrocyte precursor cells (OPCs) and oligodendrocytes (OLs). In the grey matter of the cortex, nearly all OPCs divide slowly, yet they do not differentiate solely into mature OLs, leaving the exact role of these OPCs in the grey matter enigmatic. Oligodendroglia were traced using the sex-determining region Y-related high mobility group-box 10 (Sox10) Cre-ERT2 reporter mice. We compared the effect of tamoxifen dissolved in different solvents on the fate of Sox10 cells. We also compared the effect of tamoxifen dosage on the fate of Sox10 cells. The differentiation of labeled red fluorescent protein (RFP) cells was analyzed using immunofluorescence staining. Two groups of RFP cells, type A Sox10 (Sox10-A) cells and type B Sox10 (Sox10-B) cells, were identified in the cortex, striatum, hippocampus, thalamus, and hypothalamus. Sox10-A cells differentiate into platelet-derived growth factor receptor-\u03b2+, CD13+ pericytes, and smooth muscle myosin heavy chain 11+ smooth muscle cells when the mice received ethanol or high-dose tamoxifen. Sox10-B cells transform into glutamatergic neurons when the mice received high-dose tamoxifen. Sox10-B cells include perineuronal OPCs and OLs. This investigation provides evidence that a substantial proportion of oligodendroglia in the grey matter serve as mural cell precursors and neuronal precursors. These two phenomena may contribute to our understanding of the fate of oligodendroglia.\n\nID: 41106325\nTitle: Neurotoxicity of propylene glycol butyl ether: Multiomic evidence from human brainspheres.\nAbstract: Exposure to solvents may contribute to the development of neurodevelopmental and neurodegenerative diseases. Glycol ethers consist in a widely used class of organic solvents leading to workers and consumers exposure via many applications. Ethylene glycol ethers are gradually being replaced by propylene glycol ethers thought to be less toxic. However, their neurotoxicity is not systematically assessed before placing them on the market. Therefore, this study investigated the potential neurotoxicity of propylene glycol butyl ether (PGBE) for which no official occupational limit has been established. To this aim, new approach methodologies have been used. Human induced pluripotent stem cells-derived BrainSpheres model was exposed to PGBE and to its assumed human main metabolite, 2-butoxypropanoic acid (2BPA). An integrative multiomic approach (transcriptomics, proteomics, metabolomics and lipidomics) was adopted to assess molecular alterations, derive benchmark concentrations and define potential mechanisms of action. PGBE was neurotoxic at occupationally relevant exposure concentrations. This was shown for the first time in human cells. Although PGBE was more cytotoxic than 2BPA, both compounds showed very similar neurotoxicity. PGBE and 2BPA strongly affected the cell cycle, induced oxidative stress and perturbed energy and lipid metabolism. They also targeted specific nervous system processes, such as axon guidance and synapse organization. Finally, 2BPA might trigger ferroptosis by increased iron uptake. Our in vitro results show an urgent need for public health authorities to carefully assess the risk glycol ethers pose to humans, to properly protect the workers as well as individuals in the general population unknowingly exposed from indoor air contaminations.\n\nID: 41073005\nTitle: MALDI matrix sublimation versus spray coating in the FluoMALDI imaging pipeline.\nAbstract: This study advances the FluoMALDI pipeline for tissue autofluorescence applications by integrating slide-scanning fluorescence microscopy (SSFM) with matrix-assisted laser desorption/ionization (MALDI) imaging to target autofluorescent tissue structures. Mouse brain, liver, and kidney tissues were used to systematically compare the two matrix deposition methods of sublimation and spray coating in the FluoMALDI pipeline. Half of each tissue section was left uncoated as control by covering it during matrix application. Six MALDI matrices including 9-aminoacridine, norharmane, \u03b1-cyano-4-hydroxycinnamic acid, 2,5-dihydroxyacetophenone, 2,5-dihydroxybenzoic acid, or sinapinic acid were applied in equal amounts. Autofluorescence enhancements were evaluated using three fluorescence channels in the green, red, and far-red range of the spectrum, revealing matrix- and tissue-dependent fluorescence enhancement profiles. Norharmane matrix resulted in the most consistent tissue autofluorescence enhancements across deposition methods, with the highest enhancements in the green channel when applied by spray coating, and in the red and far-red channels when applied by sublimation coating. Matrix crystal size did not significantly impact the observed fluorescence enhancement effects for all six tested matrices. The two ionization modes of MALDI-1 and MALDI-2 imaging were also compared on brain, liver, and kidney tissue sections to assess lipid detection efficiency and spatial distribution in the FluoMALDI imaging pipeline. While the spatial distributions of phosphatidylethanolamine (PE) and phosphatidylcholine (PC) species were consistent across MALDI ionization modes and matrix deposition methods, lipid detection efficiency varied depending on the matrix type, matrix crystal size, tissue type, and MALDI ionization mode. Sublimation, which produced fine crystals without solvents, generally resulted in higher phospholipid detection efficiency than spray coating for lipids including PE(36:2) and PC(36:2) in both MALDI-1 and MALDI-2 imaging. These findings highlight that the matrix choice and matrix deposition method applied significantly affect tissue autofluorescence enhancement, spatial resolution, and lipid detection efficiency in MALDI-1 and MALDI-2 imaging modes, offering valuable insights for selecting optimal matrix deposition for FluoMALDI imaging based on a given study's research goals.\n\nID: 42613522\nTitle: Analysis of Ganglioside Molecular Species Focusing on Ceramide Structures Using Thin-Layer Chromatography-Mass Spectrometry.\nAbstract: Thin-layer chromatography is widely used for the analysis of glycolipids and phospholipids. Typically, after separation with various solvents, molecular species are identified by chemical detection or immunostaining. This chapter describes a method for structural analysis of molecules by directly performing mass spectrometry after chromatographic separation. We introduce a classical ganglioside analysis method and a technique for structure analysis of separated lipids using a robotic ion source for direct MS analysis.\n\nID: 42611965\nTitle: Harnessing ternary quasi-hydrophobic natural deep eutectic solvents for in situ decomposition dispersive liquid-liquid microextraction: a sustainable analytical approach for triazole pesticides in aquatic environments.\nAbstract: Triazole fungicides (TFs) are difficult to determine in environmental water due to their high polarity, water solubility, and complex matrix interferences, while conventional extraction techniques are often plagued by low enrichment efficiency and high organic solvent consumption. To address these limitations, a novel effervescent-assisted dispersive liquid-liquid microextraction (EA-DLLME) strategy based on ternary quasi-hydrophobic natural deep eutectic solvents (NADESs) was developed. The NADESs, composed of terpenoids, long-chain alcohols, and short-chain carboxylic acids, were synthesized and combined with Na2CO3 to form an effervescent system. The hydrophilicity of the short-chain carboxylic acid enabled in situ decomposition, while the agitation effect of CO2 bubbles facilitated rapid extraction. FT-IR and 1H NMR characterized the solvent structure and dispersion mechanism. Under optimized conditions via response surface methodology and GC-MS analysis, the method exhibited a linear range of 0.5-1000 ng mL-1 (R2 > 0.99) for the three target TFs (myclobutanil, tebuconazole, and epoxiconazole), with limits of detection of 0.017-0.030 ng mL-1. The recoveries of spiked samples ranged from 89.17% to 111.2%, with relative standard deviations below 9.5%. Density functional theory calculations including electrostatic potential, Independent Gradient Model, and Reduced Density Gradient reveal that the NADES forms through electrostatic complementarity and a hydrogen-bond network, and that the extraction with TFs occurs via directional hydrogen bonding between triazole nitrogen and the hydroxyl group of thymol, with a binding energy of -23.66 kcal mol-1, further stabilized by van der Waals forces. This approach effectively overcomes the poor retention and low efficiency associated with traditional reversed-phase extraction, offering a simple, green, and practical tool for monitoring trace TFs in complex water samples.\n\nID: 42609009\nTitle: Mass Spectrometry-Based Anti-Doping Analysis: A Critical Review of Emerging Analytical and Sample Pretreatment Strategies.\nAbstract: Illicit use of doping substances has raised significant ethical and health concerns in sports. Therefore, continuous doping control is essential for maintaining fairness and athlete's safety. Accurate and rapid detection of prohibited substances at their lowest levels in complex biological matrices, such as blood, urine, and plasma, is crucial for reliable anti-doping analysis. This critical review focuses on the applications of mass spectrometry (MS) for the detection of doping agents across diverse biological matrices. Special emphasis is given to advanced mass spectrometry platforms, particularly LC-QQQ-MS, LC-QTOF-MS, Orbitrap-MS/MS, and IRMS which are widely used for the routine screening, confirmation, and identification of emerging doping agents. Microsampling approaches such as dried blood spots (DBS) and volumetric absorptive microsampling (VAMS) provide superior alternatives to traditional sampling. Furthermore, comprehensive understanding of sample pretreatment and analytical techniques is essential. In this regard, novel microextraction techniques, including solid-phase microextraction (SPME), liquid-phase microextraction (LPME), supramolecular solvents (SUPRAS), and deep eutectic solvents (DES), have improved multi-analyte sample pretreatment strategies and facilitated advanced automation. This review also offers valuable guidance in selecting appropriate chromatography coupled mass spectrometry\u2011based analytical methods with sensitive detection, sample pretreatment techniques, and storage conditions during sports drug testing.\n\nID: 42608938\nTitle: Comprehensive Chemical and Biological Assessment of Orobanche racemosa Extracts Using Chromatographic, In Vitro, In Silico, and Cell-Based Techniques.\nAbstract: The growing interest in natural product research as a safer and sustainable alternative to synthetic drugs has triggered this study, which evaluates the chemical profile and biological activity of Orobanche racemosa extracts. In the current study, extraction was performed from O. racemosa using the maceration method with several extraction solvents. The extracts were examined for their antioxidant and enzyme-inhibitory activities and their effects on cell viability. In high-performance liquid chromatography-MS/MS analysis, a total of 31 compounds was detected across all studied extracts. The EtOH and EtOH/water extracts consistently exhibited the highest antioxidant capacities in almost all tested assays. Similarly, EtOH and EtOH/water extracts showed vigorous anti-AChE activity, measuring 2.88 and 2.35\u2009mg/GALAE, respectively. In the cell viability assay, both EA and EtOH extracts of O. racemosa demonstrated potent cytotoxicity, significantly reducing viability in normal (HEK293) and cancer cell lines (HepG2, SH-SY5Y), indicating high toxicity without selectivity. Molecular docking screened 384 theoretical compound-target combinations and retained 251 unique complexes with docking scores of -7.0 kcal/mol or lower after duplicated entries were removed. Subsequent single-trajectory molecular dynamics analysis of seven representative high-scoring complexes generated hypotheses regarding structural persistence under the simulated conditions; however, these computational predictions require experimental validation.\n\nID: 42604606\nTitle: Ultrasound-assisted deep eutectic solvent extraction and macroporous resin enrichment of polyphenols from Cortex Mori: Screening of tyrosinase inhibitors via affinity ultrafiltration-LC-MS and molecular docking.\nAbstract: Cortex Mori, the dried root bark of Morus alba L., is a rich source of polyphenolic compounds. In this study, an ultrasound-assisted deep eutectic solvent (UAE-DES) strategy was developed for the efficient extraction of polyphenols from Cortex Mori, combined with macroporous resin enrichment and subsequent chemical and functional characterization. Among 36 deep eutectic solvents evaluated, betaine-sucrose (DES-6) exhibited the best extraction performance. Response surface methodology optimized the UAE-DES conditions as 35% water content, 57 \u00b0C, liquid-to-solid ratio of 90 mL/g, ultrasound time of 20 min, and power of 520 W, achieving a total phenolic yield of 232.93 \u00b1 0.95 mg GAE/g, which was 28.31% and 32.78% higher than the highest yields obtained using methanol and ethanol, respectively. Scanning electron microscopy revealed that ultrasound-DES treatment caused pronounced erosion, pore formation, cracking, and partial collapse of plant cell walls, thereby facilitating solvent penetration and mass transfer. After purification using HPD-100 resin, UHPLC-Q-Orbitrap HRMS identified 58 polyphenolic compounds, including 11 reported from Cortex Mori for the first time. The 70-W2 fraction exhibited strong tyrosinase inhibitory activity (IC50 = 1.92 \u00b1 0.03 \u00b5g/mL), surpassing kojic acid (IC50 = 12.54 \u00b1 0.21 \u00b5g/mL). Affinity ultrafiltration coupled with LC-MS (UF-LC-MS) screening identified seven potential tyrosinase-binding ligands. Molecular docking showed that 2-hydroxynaringenin 4'-O-glucoside had the most favorable predicted docking score (-10.5 kcal/mol), followed by mulberroside A and 5,7,2',6'-tetrahydroxyflavanone. These candidates require further biochemical and in vivo validation. In addition, the optimized DES retained 90.51 \u00b1 2.28% of its initial extraction performance after the third reuse cycle, while FTIR, viscosity, and density analyses supported its short-term physicochemical stability. These results demonstrate that ultrasound-assisted deep eutectic solvent extraction provides an integrated and resource-efficient approach for polyphenol recovery, activity-oriented enrichment, and prioritization of potential tyrosinase-binding constituents from Cortex Mori.\n\nID: 42601634\nTitle: Chemical investigation and anti-trichinellosis activity of some ficus species leaves: in silico supported in vitro study.\nAbstract: Worldwide, trichinellosis is a zoonotic illness. Albendazole (ALB), the nowadays anti-trichinellosis drug, has side effects and insufficient effectiveness. Ficus species have ubiquitous health benefits. The current work aimed to assess the in vitro anti-trichinellosis potential of seven Ficus species compared to the reference drug, ALB. Fourteen crude extracts from seven Ficus species (spp.) leaves were prepared using 70% methanol and aqueous solvents. Trichinella spiralis (T. spiralis) adult worms were isolated from infected mice, cultivated on a 24-well tissue culture plate, and subjected to the crude Ficus spp. extracts and ALB in culture media. The efficacy of the tested compounds was evaluated using parasitological analysis and electron microscopy (SEM). Preliminary phytochemical screening and total phenolic content were performed on Ficus spp. extracts showing the most promising effects. In addition, GC-MS analysis was performed on the most active extract to determine its chemical composition. The parasitological analysis revealed that Ficus microcarpa (F.m) had the most promising effects, followed by Ficus sycomorus (F.s) and Ficus nitida (F.n) with the methanolic extracts' LC50 of 12.8\u00a0\u00b5g/mL, 31.5\u00a0\u00b5g/mL, and 42.9\u00a0\u00b5g/mL, respectively, compared to the ALB (52.5\u00a0\u00b5g/mL). SEM results documented changes and a loss of the typical tegumental structure and morphology in adult T. spiralis worms. The GC-MS analysis of F.m methanolic extract yielded 26 compounds, including fatty acids, esters, tricyclic diol, and glucosinolates. Molecular docking studies further supported these results, with high binding affinities among the major compounds of F.m and the tubulin beta chain of T. spiralis, an essential protein for parasite survival. The current study emphasizes the promising potential of Ficus species, especially F.m, as natural sources for the development of antiparasitic agents for the therapy of trichinellosis.\n\nID: 42589302\nTitle: Solvent Interaction Analysis: A New Lens for Protein Structure and Diagnostics.\nAbstract: Aqueous two-phase systems (ATPSs) provide a versatile, fully aqueous platform for probing solute-water interactions and protein structure. This review first surveys the diversity and phase behavior of biphasic aqueous systems formed by polymers and salts. We describe how phase diagrams characterize ATPS formation and composition and how both polymer chemistry and salt identity, rather than molecular size alone, govern phase separation by modulating the solvent properties of water. Building on a modified binodal model, we show that phase separation and solute partitioning can be understood in terms of changes in aqueous solvent dipolarity/polarizability, hydrogen-bond donor/acceptor properties, hydrophobicity, and electrostatics, quantified via solvatochromic probes and homologous solute series. These measurements underpin solvent interaction analysis (SIA), in which the partition coefficients of small molecules and proteins across panels of ATPSs are used to generate \"structural signatures\" that sensitively report on amino acid substitutions, conformational changes, aggregation, ligand binding, osmolyte effects, and post-translational modifications, independent of protein size. We discuss how SIA can be implemented in vial-, plate-, and microfluidic formats and combined with diverse analytical readouts (HPLC, MS, colorimetric assays, and immunoassays), and we contrast this structure-focused approach with conventional concentration-only proteomic and biomarker strategies. Particular emphasis is placed on structure-based biomarker discovery, where disease-relevant shifts in proteoform distributions-especially glycosylation changes-are often more informative than bulk protein levels and where SIA can complement or simplify complex glycomics and top-down proteomics workflows. As a case study, we describe the recently FDA-approved IsoPSA assay, which applies SIA principles to prostate-specific antigen by measuring cancer-associated structural alterations in circulating PSA via its partition behavior in a proprietary ATPS. IsoPSA generates a single index that discriminates between high-grade prostate cancer and benign and low-grade conditions. Prospective, longitudinal, and MRI-integrated clinical studies demonstrate that IsoPSA improves pre-biopsy risk stratification, reduces unnecessary biopsies, and provides robust negative and positive predictive values within the PSA \"gray zone.\" Collectively, the data support aqueous solvent interaction analysis as a broadly applicable, mechanistically grounded technology for protein characterization, drug-protein interaction studies, and structure-centric biomarker development, exemplified by the clinical translation of IsoPSA.\n\nID: 42588580\nTitle: Comparative Metabolite Profiling of Different Solvent Extracts of Argemone ochroleuca Sweet and Argemone mexicana Linn Shoots and Roots Using Liquid Chromatography-Mass Spectrometry-Based Metabolomics and Molecular Networking.\nAbstract: Argemone ochroleuca and Argemone mexicana are widespread weed species known for being rich in various secondary metabolites. However, a comprehensive understanding of their chemical diversity remains limited. Insufficient information exists on metabolite variation between plant parts and the influence of solvent polarity on metabolite recovery. Therefore, this study aimed to characterize the metabolomic profiles of the shoots and root extracts of both species using solvents of varying polarity to evaluate plant part-specific metabolite distribution and solvent effects on metabolome coverage. Untargeted ultra-high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS)-based metabolomics and molecular networking were employed for metabolite analysis. Principal component analysis (PCA) did not reveal clear clustering of A. ochroleuca and A. mexicana, suggesting similarities in their metabolomic profiles. A total of 15 and 13 metabolite classes, yielding 59 and 54 metabolites, were identified in A. ochroleuca and A. mexicana, respectively, including flavonoids, terpenoids, phenolic compounds, fatty acids, and monoterpenoids. Argemone ochroleuca exhibited higher metabolite abundance, particularly in methanol and acetone extracts, and with shoots showing higher abundance than roots, with flavonoids being the dominant class. The findings show that LC-MS metabolomics, molecular networking, and careful solvent selection are effective for identifying key metabolites with potential applications in crop protection.\n\nID: 42586390\nTitle: Dichloromethane extract is responsible for the Evodiae Fructus induced hepatotoxicity via PI3K-AKT/MAPK/p53/NF-\u03baB signaling pathways through integrated network pharmacology, proteomic and transcriptomic analyses.\nAbstract: Tetradium ruticarpum (A.Juss.) T.G. Hartley (syn. Evodia rutaecarpa (Juss.) Benth., Rutaceae), known as Wuzhuyu in Chinese and Evodiae Fructus (EF) in English, is a traditional Chinese medicine (TCM) with a history of over two thousand years. It was first documented in Shen Nong's Herbal Classic for its efficacy in dispersing cold, relieving pain, and alleviating nausea, vomiting, and diarrhea, leading to its historical use in managing gastrointestinal ailments. However, the clinical application of EF has been limited due to its associated hepatotoxicity. Existing studies have confirmed that evodiamine, rutaecarpine and other alkaloids induce hepatotoxicity via multi-pathways, but the core toxic fraction, multi-component synergistic effects and systematic toxic network of EF remain unclear. This study aims to identify the key hepatotoxic fraction of Evodiae Fructus (EF) and elucidate its underlying mechanisms. A high-throughput zebrafish model was used to screen EF extracts with different polar solvents. The hepatotoxicity of the target fraction was validated in mice. UPLC-Q-TOF-MS/MS, integrated network pharmacology, proteomic and transcriptomic analyses were performed in zebrafish and mice to screen toxic pathways, with western blot and qRT-PCR validation. High-throughput zebrafish screening of five polar extracts of EF identified the dichloromethane extract (DEEF) as the core hepatotoxic fraction. Both zebrafish and mouse models consistently indicated that DEEF induced a dose-dependent elevation of serum ALT, AST, and TBA levels, disrupted the architecture of hepatic tissue, and was accompanied by marked hepatocyte apoptosis. In mice, Masson's trichrome staining further revealed abnormal collagen deposition, along with extensive infiltration of inflammatory cells. UPLC-Q-TOF-MS/MS analysis identified 73 compounds in DEEF, with 48 alkaloids (indole and quinolone types) being the dominant components, in addition to flavonoids, limonoids, and organic acids. Integrated network pharmacology, transcriptomic and proteomic analyses revealed dose-dependent global alterations in hepatic gene and protein expression profiles. Mechanistically, DEEF upregulated bile acids (BAs) synthesis enzymes (CYP7A1, CYP27A1) and downregulated efflux transporters (BSEP, MRP2). These changes were associated with activation of PI3K-AKT/MAPK/p53/NF-\u03baB pathways and modulation of the Bax/Bcl-2/Caspase-3 apoptotic axis, as indicated by multi-omics enrichment and validated by protein and gene expression analyses. This study is the first to confirm that DEEF represents the core toxic fraction of EF and to disclose that its hepatotoxic mechanism is driven by the crosstalk between BAs metabolism disorder and multi-signaling cascade. Our findings fill the research gap between studies on crude extract and monomers, and provide a critical foundation for targeted detoxification and safe clinical application of EF.\n\nID: 42578478\nTitle: Fluorinated EC analogues as co-solvents in EMC-based electrolytes for Li-ion batteries: a computational study.\nAbstract: The growing demand for high-energy-density lithium-ion batteries calls for electrolytes capable of stable operation at elevated voltages. Conventional carbonate-based systems, such as ethylene carbonate (EC) and ethyl methyl carbonate (EMC), suffer from limited oxidative stability and rapid degradation under such conditions. Fluorination of carbonates has emerged as an effective strategy to enhance electrochemical stability and cycling performance. In this study, we computationally investigate electrolyte formulations composed of EMC and fluorinated EC derivatives as co-solvents to elucidate how molecular fluorination influences solvation structure and ion transport. Quantum mechanical calculations reveal that among the studied species, trans-difluoroethylene carbonate (DFEC) exhibits the widest HOMO-LUMO gap (8.727 eV), indicating a higher electrochemical stability window, whereas non-fluorinated EC shows the strongest Li+ coordination, consistent with its superior ion-pair dissociation ability. Radial distribution functions and cluster analyses further confirm that electrolytes containing fluorinated solvents exhibit weaker ionic dissociation and higher ion aggregation compared to the EC-based system. While most fluorinated systems show a substantial increase in single-ion diffusion, true ionic conductivity is generally decreased upon fluorination with the exception of TFPC/EMC. This decrease is due to extensive clustering and absence of cyclic co-solvent in Li+ coordination, both of which lead to the formation of fewer charge carriers. The TFPC/EMC and FEC/EMC formulations exhibit comparable ionic conductivity values to EC/EMC (3.02 mS cm-1 and 2.74 mS cm-1 respectively, compared to 2.85 mS cm-1) and are both the highest among the fluorinated systems. Finally, van Hove correlation analysis provides a detailed view of Li+ transport, revealing that the short-time peak of Li+ generally decays more prominently and displaces farther upon fluorination.\n\nID: 42577649\nTitle: Revaluation of Granadilla (Passiflora ligularis): Analysis of Phenolic Compounds and Their Antioxidant Activity.\nAbstract: This study is aimed at evaluating the effect of solvents such as ethanol and methanol on the extraction of phenolic compounds with antioxidant capacity from granadilla (Passiflora ligularis). Extraction was assisted with ultrasound (40\u2009kHz, 30\u00b0C). The sample-to-solvent ratio was 1:14, and extraction was performed separately for seeds and peels. The proximate composition of peel and pulp stood out for their high carbohydrate content (52.12 and 90.99\u2009g/100\u2009g d.m., respectively), whereas the seeds showed values of fiber, protein, and fat of 29.48, 26.33, and 23.77\u2009g/100\u2009g d.m., respectively. Methanol was the most effective solvent for the extraction of phenolic compounds, and seeds were the highest source of these compounds, reaching a value of 36.26\u2009mg GAE/g extract. The in vitro antioxidant capacity had similar behavior, with values of 7816.9\u2009\u03bcmol Fe (II)/g d.m. extract for the FRAP assay and 1161.507\u2009mmol TE/100\u2009g extract for ABTS assay. The HPLC-MS analysis identified some phenolic compounds present in the peel extracts such as epigallocatechin gallate, quercetin and resveratrol and additionally to them, rutin for the seed extracts.\n\nID: 42576418\nTitle: Dopant-Assisted APCI for Enhanced Sugar Analysis: Overcoming Ionization Bottlenecks.\nAbstract: The investigation of lignocellulosic biomass by atmospheric-pressure chemical ionization (APCI) mass spectrometry (MS) has revealed significant issues for carbohydrate ionization, particularly during biomass pyrolysis analyses. Unequal ionization of carbohydrates and significant fragmentation have been reported. The introduction of suitable dopants into the ion source shows promise for limiting fragmentation. To investigate these ionization disturbances, both direct infusion (DI) and modified direct insertion probe (DIP) APCI coupled with a Fourier-transform ion cyclotron resonance mass spectrometry (FT-ICR MS) were employed. Solvents with increasing proton affinity (PA) were used to assess solvent PA influence in DI-APCI ionization processes. The DIP system was modified to enable the introduction of an inert gas stream passing through a dopant-rich atmosphere prior to entering the ion source. A significant PA difference between the solvent and the analyte promotes carbohydrate dissociation after their ionization. Experiments without solvent and with deuterated compounds showed that carbohydrate ionization and dissociation may be self-induced by water formed during carbohydrate dehydration. The introduction of ammonia in the ion source promoted the [M\u2009+\u2009NH4]+ adduct formation, reducing ionization-induced dissociation and increasing the intensity of the carbohydrate signal by at least one order of magnitude in DI-APCI. The method was successfully applied to both standards and cellulose pyrolysis samples. The dopant-assisted APCI (dAPCI) approach appears highly promising for the rapid assessment of biomass fast pyrolysis, particularly when highly oxygenated compounds are key markers. Careful selection of dopants and solvents is essential in carbohydrate analysis to preserve analyte structural integrity during ionization.\n\nID: 42575926\nTitle: Phytochemical profile and in vitro antimicrobial, antiviral, and anticancer activities of Echium angustifolium ethanolic extract.\nAbstract: Echium angustifolium is traditionally valued for its therapeutic properties; yet comprehensive studies on its biological activities are limited. Aerial flowering parts were sequentially extracted with solvents of varying polarity. Extracts were analyzed for yield, phytochemical composition, and total phenolic and flavonoid contents and HPLC.\u00a0LC-MS/MS analysis in negative ion mode was performed for detailed compound identification. Antioxidant activity was measured using the DPPH assay. Antibacterial activity against Gram-positive and Gram-negative bacteria was evaluated via agar diffusion and MIC/MBC methods. Anti-inflammatory potential was determined in vitro through RBC membrane stabilization (hemolysis) assay. Cytotoxicity and antiviral activity were examined using MTT and cell-based assays on HepG2 and Vero cells. The molecular mechanism of anticancer activity was investigated through qPCR analysis of apoptosis-related genes (Bax, Caspase-3, Caspase-9, and Bcl-2) in HepG2 cells. Antiviral efficacy against Hepatitis A virus (HAV) and Coxsackievirus B4 (CoxB4) was further validated by RT-qPCR quantification of viral RNA copy numbers. The ethanolic extract showed the highest yield (14.23%) among the tested solvents and richest phytochemical profile, with rutin as the predominant compound.\u00a0LC-MS/MS identified 24 compounds including threonic acid, hypoxanthine, indole-3-carboxylic acid, N-methyllysine, 4-methyl-2-oxovaleric acid, 4-isopropylbenzoic acid, methionine, N-2-fluorenylacetamide, arachidic acid, N-methylanthranilic acid, carbocysteine, fructose-1,6-bisphosphate, lumazine, 5-aminoimidazole-4-carboxamide, and 3-isochromanone. It exhibited significant antioxidant activity (IC50\u2009=\u200921.08\u00a0\u00b5g/mL) and antibacterial effects against both Gram-positive and Gram-negative bacteria. It exhibited in vitro anti-inflammatory effects via RBC membrane stabilization (95.5% inhibition at 1000\u00a0\u00b5g/mL) and dose-dependent cytotoxicity against HepG2 cells (IC50\u2009=\u200994\u00a0\u00b5g/mL), while showing low toxicity toward Vero cells (IC50\u2009=\u2009632.24\u00a0\u00b5g/mL).\u00a0Mechanistically, qPCR analysis revealed that the extract at IC50 concentration significantly upregulated pro-apoptotic\u00a0Bax\u00a0(4.21-fold),\u00a0Caspase-3 (5.02-fold), and Caspase-9 (4.08-fold), while downregulating anti-apoptotic\u00a0Bcl-2 (0.33-fold) compared to untreated controls, confirming apoptosis induction through the intrinsic mitochondrial pathway.\u00a0Antiviral assays revealed significant inhibition of HAV and Coxsackievirus B4 replication at non-toxic concentrations.\u00a0RT-qPCR quantification demonstrated that the extract at MNTC (250\u00a0\u00b5g/mL) reduced HAV and CoxB4 viral RNA copies by 50.6% (from 1.22\u2009\u00d7\u2009106 to 6.03\u2009\u00d7\u2009105 copies/mL for HAV; from 2.47\u2009\u00d7\u2009105 to 1.22\u2009\u00d7\u2009105 copies/mL for CoxB4), providing direct evidence of viral inhibition. The ethanolic extract of\u00a0E. angustifolium\u00a0exhibited multifunctional in vitro bioactivities, including antioxidant, antimicrobial, anti-inflammatory, anticancer, and antiviral effects.\u00a0LC-MS/MS identified a diverse array of bioactive compounds, while mechanistic studies revealed apoptosis induction via the mitochondrial pathway (upregulation of Bax, Caspase-3, and Caspase-9; downregulation of Bcl-2) and direct antiviral activity through inhibition of viral replication (confirmed by RT-qPCR).\u00a0These findings validate the traditional medicinal uses of E. angustifolium and highlight its potential as a promising source of bioactive compounds that warrant further in vivo and mechanistic investigations.\n\nID: 42573816\nTitle: Deep eutectic solvent-based extraction and recovery of phenolic compounds: From conventional media to switchable recovery strategies.\nAbstract: Phenolic compounds are widely distributed in plant-derived matrices and are important targets in food, pharmaceutical, agricultural, and biomass-utilization fields. Their reliable determination depends strongly on efficient sample preparation, but conventional organic solvent extraction often raises concerns related to solvent consumption, toxicity, selectivity, and sample-cleanup burden. Deep eutectic solvents (DESs) have been widely explored as tunable extraction media for phenolic compounds because their polarity, viscosity, hydrogen-bonding capacity, and solvation behavior can be adjusted by changing the hydrogen-bond acceptor, hydrogen-bond donor, molar ratio, and water content. However, conventional DES systems still face important limitations, including slow mass transfer caused by high viscosity, difficulty in solvent removal due to low volatility, incomplete analyte recovery, and possible interference with chromatographic or mass-spectrometric analysis. This review summarizes conventional DES-based extraction of phenolic compounds as the baseline, and then focuses on responsive switchable DESs (RS-DESs) as recovery-oriented solvent systems. RS-DESs can undergo reversible changes in phase behavior, polarity, miscibility, or solvation ability in response to temperature, pH, CO2/N2, or ionic strength, thereby facilitating extraction, phase separation, analyte recovery, and solvent recycling. Particular attention is paid to extraction mechanisms, structure-property relationships, quantitative comparison with conventional DES systems, and analytical compatibility with HPLC, LC-MS, and related sample-cleanup workflows. Finally, the review discusses current scientific, analytical, and industrial challenges, including switching reproducibility, phenolic stability, DES residues, matrix effects, toxicity, biodegradability, and scale-up feasibility.\n\nID: 42573342\nTitle: Benchmarking Fourier Transform Ion Cyclotron Resonance Mass Spectrometry against Conventional Methods for the Characterization of Solvent-Fractionated Kraft Lignin.\nAbstract: Lignins are heterogeneous aromatic biopolymers whose structural complexity depends strongly on botanical origin and isolation process. Comprehensive characterization therefore typically relies on multiple complementary techniques, including gel permeation chromatography (GPC), Fourier transform infrared spectroscopy (FT-IR), pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS), and nuclear magnetic resonance (NMR) spectroscopy, resulting in labor-intensive workflows and complex data integration. Here, ultrahigh-resolution Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) is systematically benchmarked against these established methods using solvent-fractionated spruce kraft lignin as a model system. Complementary electrospray ionization (ESI) and graphite-assisted laser desorption/ionization (GALDI), combined with tandem mass spectrometry (MS/MS) and heterospectroscopic correlation analysis, reproduce fraction-dependent trends in oxygenation, aromatic condensation, and functional group distribution consistent with FT-IR, Py-GC/MS, and quantitative NMR data. While limitations remain for molar mass distributions and linkage quantification, FT-ICR-MS can serve as an advanced, high-throughput complementary screening platform that enables streamlined, comparative molecular-level lignin profiling with reduced analytical complexity.\n\nID: 42551130\nTitle: Optimization and validation of a two-step extraction dispersive liquid-liquid microextraction (UA-DLLME) method for the determination of 17 antibiotics in influent wastewater.\nAbstract: A rapid and efficient method based on two-step dispersive liquid-liquid microextraction (DLLME) was developed for the simultaneous determination of antibiotics belonging to six different subclasses (fluoroquinolones, macrolides, sulfonamides, lincosamides, nitroimidazoles and trimethoprim) in influent wastewater samples. Analysis was performed using ultra-performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS). During method optimization, several parameters affecting DLLME performance were evaluated: the type and volume of extraction and dispersive solvents, sample pH, sample volume, salt content (sodium chloride) for the salting-out effect, and ultrasonication time. Under optimized conditions, the method's performance characteristics exhibited linearity between 100 and 4000 ng/L (R\u00b2 \u2265 0.98). The matrix effect (ME) ranged from 32.5% to 93.3%. Recovery values were satisfactory, mostly ranging between 80% and 120%. Relative standard deviation (RSD) values indicated good repeatability and intermediate precision (< 20%), while limits of quantification (LOQs) ranged from 10.7 to 369 ng/L. Finally, the validated method was applied to the analysis of influent wastewater samples collected from the Psyttalia Wastewater Treatment Plant.\n\nID: 42568982\nTitle: Extractable and Leachable Studies on Electronic Nicotine Delivery System (ENDS) Components and E\u2011liquid Containers.\nAbstract: Electronic nicotine delivery system (ENDS) components and e-liquid containers may influence the chemical composition of inhaled aerosols, potentially impacting user exposure and the product's appropriateness for the protection of public health. Extractable and leachable (E&L) studies are crucial for identifying the chemicals that migrate to the e-liquids from the components and containers housing the e-liquids during storage and inform the potential ENDS risks to public health. There are few published ENDS E&L studies that provide limited information regarding the components and e-liquid containers. Thus, this study includes extractable testing followed by leachable testing that are designed to comprehensively examine and determine the chemicals that migrate to the e-liquid from closed ENDS components and e-liquid containers (low-density polyethylene (LDPE) bottles, polyethylene terephthalate (PET) bottles). Testing was conducted by Eurofins BioPharma Product Testing laboratory, a contract laboratory specializing in pharmaceutical extractable and leachable analyses. Semiquantitative and nontargeted analyses were conducted using gas chromatography-mass spectrometry (GC-MS) for volatile compounds and ultra-high-performance liquid chromatography-photo diode array-mass spectrometry (UPLC-PDA-MS) for semi- and nonvolatile compounds. Semiquantitative and targeted analyses were conducted using GC-MS-selected ion monitoring (GC-MS-SIM) for polycyclic aromatic hydrocarbons (PAHs) and inductively coupled plasma MS (ICP-MS) for metals. All relevant peaks were tentatively identified using mass spectral libraries and identification criteria. Across all 47 products examined in the extractable study, 19 unique (i.e., distinct, identified compounds after removing duplicates) and 101 unknown semi- and nonvolatile compounds, 1591 unique and 18 unknown volatile compounds, 9 unique PAHs, and 12 unique metals were observed. The five products from each product type with the highest number and concentration of extractables above the preestablished thresholds across all four analytical methods were examined in the leachable study. Closed ENDS had the greatest number of leachables (243 compounds), while LDPE and PET bottles had comparable numbers of leachables (53-65 compounds). In summary, this study details a comprehensive E&L analysis and peak identification approach for ENDS. These findings demonstrate that established pharmaceutical E&L methodology can be applied to ENDS components and e-liquid containers, and certain methodological parameters (e.g., selection of solvents and libraries) may need to be optimized for ENDS products.\n\nID: 42556666\nTitle: Solvent-directed ozonolysis dismantles lignin heterogeneity: An integrated strategy for a tunable lignin biorefinery.\nAbstract: Impurities and the heterogeneous three-dimensional structure of alkali lignin complicate its valorization. In this study, technical alkali lignin from soda bagasse was ozonated in ethanol, tetrahydrofuran (THF), 1,4-dioxane, acetone, or methyl cellosolve to combine oxidative depolymerization with solvent fractionation. The comparison tested how solvent polarity and hydrogen-bonding behavior affect product distribution under otherwise fixed conditions. FTIR, GPC, and GC-MS showed differences among the five soluble fractions. Protic solvents retained more phenolic monomers and oligomers, whereas aprotic solvents gave more oxidized products and different H:G:S profiles. The ethanol fraction had the highest apparent thermal stability (Ea\u00a0=\u00a04.14\u00a0kJ/mol; DTG peak\u00a0=\u00a0380\u00a0\u00b0C) and the lowest Mw (856\u00a0Da). Methyl cellosolve produced the highest-Mw fraction (2985\u00a0Da) and a more balanced H:G:S distribution. Guaiacol accounted for 40.6% of the ethanol fraction, coumaran for 70.4% of the THF fraction, and syringol for 17.2% of the methyl cellosolve fraction. THF-only controls did not produce a peak assigned to coumaran in the relevant retention-time window, which supports a lignin-derived origin for this signal under the tested conditions. The screening results link solvent properties to lignin fragmentation and the composition of the soluble products. Solvent recycling, residue characterization, process optimization, and atom-resolved mechanistic studies remain to be completed.\n\nID: 42556238\nTitle: Green magnetic dispersive micro-solid phase extraction hydrophobic deep eutectic solvent nanoparticles coupled with GC-MS determination of phthalates analysis in commercial tea products.\nAbstract: Phthalates are widely used plasticisers that can migrate from food-contact materials into food, posing environmental and health risks due to their endocrine-disrupting properties. This study developed a magnetic nanoparticle-modified hydrophobic deep eutectic solvent (MNPDES)-based magnetic dispersive micro-solid phase extraction (\u03bc-dSPE) method coupled with GC-MS for determining DBP, BBP, BEHP, DCHP, and DNOP in commercial tea products. The synthesised MNPDES showed successful surface functionalisation and favourable hydrophobic interaction properties. Under optimised conditions, the method demonstrated excellent linearity (R2\u00a0=\u00a00.999), low LODs and LOQs (0.007-0.040\u00a0\u03bcg\u00a0L-1 and 0.012-0.122\u00a0\u03bcg\u00a0L-1, respectively), satisfactory recoveries (90-111%), and acceptable reusability over five cycles, with relative recoveries above 80%. Greenness assessment using Analytical Eco-Scale, ComplexGAPI, and AGREEprep confirmed an excellent Eco-Scale score and favourable green profile. Overall, the proposed method offers a sensitive and greener approach for routine phthalate monitoring in tea products.\n\nID: 42556190\nTitle: Reconciling mechanical robustness and ion transport via in-situ rigid-flexible networks for fast-charging and wide-temperature sodium batteries.\nAbstract: Gel polymer electrolytes for next-generation sodium-metal batteries (SMBs) are limited by a trade-off between mechanical robustness and ionic conductivity, which hampers fast-charging and wide-temperature applications. Herein, we address this challenge via an innovative rigid-flexible coupled polymer network, specifically synthesized by copolymerizing flexible butyl acrylate (BA) monomers with rigid triallyl isocyanurate (TAIC) crosslinkers. The rigid TAIC framework imparts exceptional mechanical integrity and electrochemical stability, while the polymerized BA matrix effectively confines solvents, enabling efficient ion-transport pathways. Moreover, the polymer network regulates the Na+ solvation environment, thereby inducing a stable, inorganic-rich solid electrolyte interphase. The rationally designed electrolyte (pBAT-1/8) achieves an ultrahigh Young's modulus of 40\u00a0MPa (125\u00a0MPa of the pBAT-1/8 skeleton) to effectively suppress dendrites, while maintaining high ionic conductivities (0.33, 1.58, and 2.11\u00a0mS cm-1 at -10, 30, and 70\u00a0\u00b0C, respectively) and a high Na+ transference number (0.51). Consequently, Na|pBAT-1/8|Na demonstrates stable cycling over 1500\u00a0h at 0.1\u00a0mA\u00a0cm-2. Remarkably, Na|pBAT-1/8|Na3V2(PO4)3 cells deliver exceptional capacity of 92.7\u00a0mAh g-1 at 5C after 2600\u00a0cycles and operate reliably under harsh conditions, including high cathode mass loading (10.3\u00a0mg\u00a0cm-2), high cut-off voltage (4.5\u00a0V), and broad operating temperature range (-10 to 70\u00a0\u00b0C). This work offers a transformative strategy to decouple mechanical and transport properties for practical high-energy-density SMBs.\n\nID: 42555187\nTitle: Organic Molecules in Zeolites for Long-Lifetime Afterglow.\nAbstract: Organic afterglow materials based on host-guest assembly have recently attracted extensive attention for their promising applications in photobiology and optoelectronics, as well as their simple and versatile preparation. However, the poor stability of the host matrix limits their actual applications. In this study, a new class of long afterglow materials with AlPO4-5 zeolite as the host matrix and various aromatic acids (terephthalic acid, 2-naphthoic acid, and 1-pyrenecarboxylic acid) as guest molecules has been developed. The prepared composites exhibit tunable afterglow emissions across the visible spectrum from blue to green to red, with lifetimes of 919, 1540, and 74\u00a0ms and intensities approximately 42, 579, and 29 times higher than those of the corresponding pure organic molecular solid powders. Studies reveal that the efficient afterglow emission primarily stems from the effective dispersion and strong adsorption of organic molecules by the zeolite matrix, as well as the host-guest coordination interactions. Remarkably, the zeolite matrix endows the composites with excellent stability against radiation, solvents, acids, alkalis, and heat, together with potential for multimodal applications. Such a combination of properties is challenging to achieve with other matrix materials. This work establishes a novel strategy for developing long afterglow materials that integrate efficient emission, robustness, and multifunctionality.\n\nID: 42554333\nTitle: A Platform for High-Throughput Chemical Analysis of Foods: Characterization of Extra Virgin Olive by Direct Mass Spectrometry and Machine Learning.\nAbstract: Poor diet is now the leading cause of early death globally. In part, this is because our complex food supply chains are increasingly at risk of overprocessing, contamination, low nutrient content, and economically motivated fraud. Chemical testing can offer insights into these concerns, but testing methods are frequently impractical. Extra virgin olive oil (EVOO) is a premium food of high nutritional value, but because of its growing popularity and high price, it can be a target for mislabeling, substitution, dilution, and/or false claims of origin. Rapid and accurate testing methods for its characterization are therefore increasingly important. We used two direct forms of mass spectrometry (MS)-laser desorption/ionization (LDI) MS and direct analysis in real time (DART) MS-to obtain complex chemical signatures of edible oils. The data generated on a set of reference samples were then used to develop and train three independent machine learning (ML) models that assess key characteristics of a test oil. We also developed a proof-of-concept DART-MS/MS assay add-on for the quantification of bioactive phenols in EVOO. Our approach accurately predicts several attributes of an edible oil based on novel markers and intricate patterns within the acquired data. Further, pure reference standards and an isotopically-labeled internal standard allow accurate quantification of the constituent phenols. Because there is no chromatography, both the mass fingerprints and quantification can be performed in seconds-minutes. The method uses low (milliliter) volumes of sample and green solvents, and when combined with ML, it offers rapid data analysis and comprehensive result interpretation.\n\nID: 42550038\nTitle: Chemical Profiling and In\u2009Vitro Assessment of Antioxidant and Antimicrobial Properties of Algerian Erica arborea L. Extracts, Strengthened by Molecular Modeling Analysis.\nAbstract: This study aimed to valorize Erica arborea L. collected in Algeria by characterizing its chemical composition and assessing the biological potential of its organic extracts. The aerial nonflowering parts were extracted using solvents of increasing polarity, allowing evaluation of chemical and biological properties of extracts. Phytochemical assays revealed that the ethyl acetate (EtOAc) fraction contained the highest levels of total polyphenols (419.58\u2009\u00b1\u20091.89\u2009\u00b5g\u2009GAE/mg), flavonoids (174.57\u2009\u00b1\u20091.93\u2009\u00b5g\u2009QE/mg), and flavonols (61.64\u2009\u00b1\u20092.49\u2009\u00b5g\u2009QE/mg). GC-MS profiling confirmed the presence of several bioactive constituents, supporting its rich chemical composition. Antioxidant activity highlighted the superiority of EtOAc extract, with IC50 of 5.07\u2009\u00b1\u20090.63\u2009\u03bcg/mL in the ABTS\u2022+ assay, 26.96\u2009\u00b1\u20091.16\u2009\u03bcg/mL in the DPPH\u2022 assay, and an A0.5 of 18.14\u2009\u00b1\u20090.57\u2009\u03bcg/mL in the FRAP test, while the phenanthroline assay showed strong reducing power across all extracts (A0.5\u2009=\u20091.25\u2009\u00b1\u20090.05-6.72\u2009\u00b1\u20090.15\u2009\u03bcg/mL). Antimicrobial activity revealed that the EtOAc fraction exhibited notable activity against Staphylococcus aureus (19.33\u2009\u00b1\u20090.57\u2009mm) and Bacillus subtilis (19.0\u2009\u00b1\u20091.0\u2009mm), while all fractions showed antifungal activity against Candida albicans and Fusarium oxysporum. Molecular docking on xanthine oxidase and DNA gyrase (GyrA and GyrB) revealed favorable interactions of several metabolites, supporting the antioxidant and antibacterial activities observed experimentally.\n\nID: 42546627\nTitle: Direct immersion single drop microextraction with hydrophobic deep eutectic solvent for the isolation of \u03b2-lactams and tetracyclines from milk.\nAbstract: The hydrophobic deep eutectic solvent (HDES) consisting of thymol and coumarin was used as an extraction medium during the isolation of the veterinary antibiotics from group tetracyclines (lymecycline LYM, oxytetracycline OTC, tetracycline TC) and \u03b2-lactams (amoxicillin AMS, ampicillin AMP). The use of deep eutectic solvents in miniaturized liquid-liquid extraction ensures the elaboration of a procedure consistent with the rules of green analytical chemistry. Single drop microextraction (SDME) technique enabling a radical reduction of HDES volume was developed for isolation of tetracyclines and \u03b2-lactams antibiotics from the bovine milk samples. The obtained microextracts were analyzed followed by the liquid chromatography method connected with tandem mass spectrometry (LC-MS/MS). The linear concentration range (1.10-8\u00a0mol\u00a0L-1-7.10-5\u00a0mol\u00a0L-1) of the studied compounds for elaborated HDES-SDME-LC-MS/MS method enables their determination in milk samples according to the normalized values (EU Regulation 37/2010).\n\nID: 42589475\nTitle: Gene-Air Pollution Interaction in Cardiovascular Disease: Lights and Shadows in a Tangled Risk Factor Network.\nAbstract: Cardiovascular disease (CVD) is the result of a complex interaction between genetic, lifestyle, and environmental factors, which may vary over the course of life. Traditional risk factors do not explain all patients' risks; thus, the research of additional biomarkers to refine cardiovascular risk prediction has attracted considerable interest in recent years. Genetic factors, as well as air pollution exposure, among nontraditional factors, have been found to be critical determinants of CV risk. Accordingly, this narrative review aims to provide a comprehensive summary of the literature (PubMed) on the combined effects of air pollution and genetic susceptibility on CVD risk. Although different limitations and pitfalls are still to be solved, available evidence suggests that genetic variants (especially genes related to detoxification and inflammation) are involved in the association between air pollution exposure and CV adverse events. Thus, this research area could provide further knowledge of the etiology of CVD, offering new tools for targeted prevention and treatment of more susceptible subjects from a more personalized medicine point of view.\n\nID: 42504319\nTitle: Neurodegeneration in Parkinson's Disease: The Role of Environmental Toxins.\nAbstract: Parkinson's disease (PD) is a rapidly growing global health challenge, with prevalence projected to reach 13-14 million cases by 2040. While aging and improved diagnostic awareness partly explain this trend, mounting evidence implicates environmental factors as critical contributors. This review synthesizes current literature on exposures such as pesticides, solvents, heavy metals, air pollutants, and infectious agents, emphasizing their mechanistic links to neurodegeneration. These factors interact with genetic susceptibility and aging, supporting the \"multiple-hit\" hypothesis, which posits that PD arises from cumulative insults rather than a single cause. Mitochondrial dysfunction, oxidative stress, neuroinflammation, and impaired protein clearance emerge as convergent pathways underlying dopaminergic vulnerability. Recent findings highlight viral infections-particularly SARS-CoV-2-as potential triggers or amplifiers of PD pathogenesis, raising concerns about long-term neurological sequelae following pandemics. Beyond individual toxins, the exposome concept underscores the lifelong interplay of physical, chemical, and social exposures in shaping disease risk. Climate-related changes, including increased air pollution and wildfire frequency, further compound these risks, suggesting a systemic dimension to PD etiology. Understanding these complex interactions is essential for developing preventive strategies, refining experimental models, and informing public health policies aimed at mitigating environmental contributions to neurodegeneration. This multifactorial perspective offers a foundation for future research targeting modifiable risk factors and resilience mechanisms in PD. Parkinson\u2019s disease (PD) is a brain disorder that affects movement and is becoming more common worldwide. While aging and genetics play a role, research shows that environmental factors\u2014such as pesticides, air pollution, industrial chemicals, and even certain infections\u2014may also increase the risk of developing PD. This article explains how these factors can damage brain cells over time. For example, pesticides and solvents can harm the parts of the brain that control movement. Air pollution and heavy metals may also contribute to brain inflammation and stress. Infections like influenza and COVID-19 could act as \u201ctriggers,\u201d making the brain more vulnerable to damage later in life. Scientists call this the \u201cmultiple-hit\u201d theory, meaning PD often results from a combination of aging, genes, and environmental exposures rather than a single cause. The review also introduces the concept of the \u201cexposome,\u201d which looks at all the things we are exposed to throughout life\u2014chemicals, air quality, diet, and even stress\u2014and how they interact with our biology. Understanding these links can help researchers find ways to prevent PD, improve treatments, and guide public health policies. In short, Parkinson\u2019s disease is not just about getting older or having certain genes. It may also be influenced by what we breathe, eat, and encounter in our environment. By studying these factors, we can work toward reducing risks and protecting brain health.\n\nID: 42503670\nTitle: Prenatal Internal Exposure to Polycyclic Aromatic Hydrocarbons, Maternal Genetic Susceptibility, and Child Growth Trajectories: Evidence from a Prospective Cohort Study.\nAbstract: Prenatal exposure to polycyclic aromatic hydrocarbons (PAHs) is a widespread environmental health concern, yet its impact on early childhood growth trajectories remains poorly understood. In a prospective birth cohort in China (PKUBC-T), we identified distinct growth trajectories from birth to age 3 years using K-means clustering for longitudinal data (N = 1467) and measured 16 plasma PAHs in first-trimester maternal samples (N = 333). Twenty maternal single nucleotide polymorphisms (SNPs) related to PAHs metabolism were genotyped. Modified Poisson and weighted quantile sum regression showed that higher prenatal PAHs exposure was associated with increased risk of rapid higher growth trajectory, with phenanthrene, pyrene, and fluoranthene contributing most. This trajectory is characterized by a marginally higher BMI Z-score at birth, followed by rapid growth during infancy and sustained high levels thereafter. Furthermore, the AHR rs2066853 variant significantly modified the association, with the positive association being observed only among mothers carrying GA/AA genotypes (RR, 2.44; 95% CI, 1.51-3.97) but not among those with GG homozygotes (P for interaction is 0.049). We provide evidence that prenatal PAHs exposure may alter early childhood growth patterns, with effects modified by maternal genetic susceptibility. If confirmed, these findings highlight the mechanistic importance of AHR signaling in environmental developmental toxicity and underscore the need for exposure reduction and targeted maternal monitoring.\n\nID: 42450038\nTitle: The Need for Omics Studies in Chronic Kidney Disease of Unknown Etiology (CKDu): A Narrative Review and Perspective.\nAbstract: Chronic Kidney Disease of Unknown Etiology (CKDu) is an ongoing global health concern, particularly affecting agricultural communities in equatorial regions. Unlike traditional chronic kidney disease (CKD), CKDu occurs without common risk factors such as diabetes, hypertension, or kidney stones. Its etiology remains poorly understood, with environmental exposures, occupational hazards, and genetic susceptibility proposed as contributing factors. Omic technologies including genomics, transcriptomics, proteomics, metabolomics, and exposomics offer promising avenues to elucidate CKDu pathogenesis by enabling comprehensive molecular profiling and identification of biomarkers. Recent genomic studies have explored single nucleotide polymorphisms (SNPs) linked to kidney injury susceptibility, while transcriptomic analyses have identified differential expression of genes involved in oxidative stress and tubular injury pathways. Proteomic investigations have revealed candidate urinary biomarkers such as heat shock proteins and inflammatory mediators, and metabolomic profiling has highlighted alterations in amino acid and energy metabolism in affected individuals. Exposomic approaches are beginning to characterize cumulative chemical exposures, including pesticides and heavy metals, in endemic regions. This narrative review synthesizes current evidence on the application of omics approaches in CKDu research, highlights knowledge gaps, and proposes future directions for integrating multi-omics studies with machine learning and artificial intelligence approaches. Advancing omics-based investigations may provide critical insights into disease mechanisms, improve diagnostic precision, and inform targeted interventions for vulnerable populations.\n\nID: 42431065\nTitle: Independent and joint effect of genetic susceptibility and long-term PM2.5 exposure on coronary artery disease risk: A large-scale cohort study.\nAbstract: Long-term exposure to fine particulate matter \u2264\u202f2.5 \u03bcm (PM2.5) is a major cardiovascular risk factor, yet its interaction with genetic susceptibility in coronary artery disease (CAD) remains uncertain. We investigated the independent and joint effects of PM2.5 and polygenic risk on incident CAD. A genome-wide polygenic risk score (PRS) was derived using a five-fold cross-validation framework in a large Taiwanese hospital-based cohort (n\u202f=\u202f351,661). In the primary analysis, 148,735 adults were followed to estimate the association between long-term PM2.5, assessed using a validated 1-km spatiotemporal model, and incident CAD. Gene-environment interactions were assessed in a subset of 60,017 participants with available genotyping data using Cox proportional hazards models. Over a median follow-up of 4.6 years, 11,127 CAD events were recorded. Each 10-\u03bcg/m3 increase in PM2.5 exposure was associated with a 14% higher hazard of incident CAD (hazard ratio [HR]: 1.14, 95% CI: 1.08-1.20), and each standard deviation increase in PRS was associated with a 7% higher hazard of incident CAD (HR: 1.07, 95% CI: 1.05-1.10). In joint analyses, PM2.5 exposure and genetic susceptibility each independently contributed to CAD hazard without significant interaction, with the highest hazard observed among individuals with both high PRS and high PM2.5 exposure (HR: 1.24, 95% CI: 1.14-1.36). Long-term PM2.5 exposure and polygenic susceptibility each independently contributed to the hazard of incident CAD, and individuals with both high genetic risk and high PM2.5 exposure had the highest observed hazard. These findings suggest that environmental exposure reduction and genetic risk identification may serve as complementary approaches to CAD prevention, particularly in populations with substantial air pollution burden.\n\nID: 42420066\nTitle: Association of long-term outdoor air pollution exposure with incidence of Parkinson's disease, multiple sclerosis and motor neuron diseases: a systematic review and meta-analysis.\nAbstract: Parkinson's disease (PD), multiple sclerosis (MS) and motor neurone disease (MND) are progressive and debilitating diseases that are increasing in prevalence globally. Some primary studies show an increased risk from long-term outdoor air pollution exposure, while others contradict this association. A systematic review and meta-analysis were undertaken to assess the associations of long-term (\u22651 year) outdoor air pollution exposure with PD, MS and MND incidence. We searched eight databases for publications up to July 2025. Primary case-control, cohort, cross-sectional or ecological studies investigating the association between long-term air pollution exposure and adult (>18\u00a0years old) PD, MS, or MND incidence were included. Meta-analyses were carried out using random-effects models with assessment of heterogeneity, meta-bias and shape of the exposure-response functions. PROSPERO (CRD42023417961). Of 42 papers included, 26, 3 and 3 were meta-analysed for PD, MS, and MND outcomes, respectively. 19 studies from North America, 12 from Europe and 10 from Asia were meta-analysed. For every 5\u00a0\u03bcg/m3 and 15\u00a0\u03bcg/m3 increase of Particulate Matter 2.5 (PM2.5) and PM10 concentration, estimated (95% Confidence Interval) PD risk was 10% (1.10; 1.03-1.19) and 18% (1.18; 1.01-1.38), respectively but effects varied across settings (Prediction Interval: 0.80-1.52 for PM2.5 and 0.41-3.36 for PM10), with the largest estimated risk for PM2.5 in Asia (1.19; 1.01-1.41). There was no clear evidence that PM2.5 (1.01; 0.77-1.32) or nitrogen dioxide (NO2, 0.98, 95% CI: 0.95-1.01) were associated with MS risk or PM2.5 with MND risk (1.07, 95% CI: 0.86-1.33). This systematic review reports increased PD risk from long-term PM2.5 and PM10 exposure. No association was observed for MS and MND from a very limited evidence base. The neurodegenerative diseases investigated here are rare and therefore alternatives to insufficiently powered cohort studies are needed to strengthen the evidence on risk.\n\nID: 42419777\nTitle: Genetic susceptibility to respiratory health effects from outdoor air pollution: a structured narrative review.\nAbstract: Outdoor air pollution exposure is a well-established driver of respiratory disease, while growing evidence highlights an important role for genetic susceptibility. Building on this expanding body of work, our review synthesises findings across studies and provides an integrated overview. Here, we present a structured literature review summarising study characteristics and statistically significant single nucleotide polymorphisms (SNPs) reported in gene-environment interaction studies of air pollution related respiratory outcomes. By consolidating this evidence, the review clarifies current findings and supports more rigorous, evidence-based risk stratification in future observational and intervention studies. We included 48 peer-reviewed studies in humans published between 2014 and 2024 that examined gene-environment interactions involving SNPs, outdoor air pollution exposure and respiratory outcomes. Studies primarily evaluating particulate matter with aerodynamic diameter <2.5\u2005\u00b5m and <10\u2005\u03bcm, and nitrogen dioxide included respiratory end-points, such as asthma, COPD and lung-function measures. The majority of analyses used regression-based methods, supplemented by mixed-effects and generalised estimating equation models. Candidate gene studies (particularly in the glutathione S-transferase (GST) family) along with polygenic risk scores and genome-wide interaction approaches identified 89 SNPs across 53 genes. Replicated variants involved pathways in oxidative stress detoxification (e.g. rs1695 (GSTP1) and rs2266637 (GSTT1)) and inflammatory responses (e.g. rs1800629 (TNF), rs3804099 (TLR2) and rs848 (IL13)), consistently modifying pollution-related lung function decline and airway inflammation. By consolidating key genes, study designs and analytic methods, this review provides a curated SNP list to inform future genetic risk stratification. We highlight the need for studies in ancestrally diverse populations, controlled human exposure designs, and multi-omics approaches to strengthen mechanistic understanding of gene-environment interactions in respiratory health.\n\nID: 42415205\nTitle: Manifestations of tuberculosis possibly associated with rituximab in a patient with diagnosed multiple sclerosis: a case report.\nAbstract: Multiple sclerosis (MS) is an autoimmune disease affecting the central nervous system. Following the elucidation of the role of B cells in MS pathogenesis, B-cell-depleting agents such as Rituximab have become increasingly utilized. However, the relationship between rituximab therapy and susceptibility to tuberculosis (TB) remains a subject of ongoing investigation, with conflicting evidence in the literature. A 55-year-old Iranian woman with multiple sclerosis who had received rituximab for five years presented with high-grade fever, chills, and suprapubic pain. One year before admission, she had developed lower-extremity skin lesions initially diagnosed as eosinophilic fasciitis and later revised to erythema nodosum. Computed tomography revealed a left ovarian mass, a right ovarian cyst, ascites, pulmonary involvement, and bilateral pleural effusions, raising concern for malignancy. Bronchoalveolar lavage polymerase chain reaction confirmed tuberculosis. The patient was treated with the World Health Organization standard anti-TB regimen (isoniazid, rifampin, pyrazinamide, and ethambutol). Rituximab was discontinued; dimethyl fumarate was introduced after four months of therapy and rituximab was reintroduced at six months. At one-year follow-up, there was no TB reactivation and no worsening of MS. This case demonstrates an atypical multisystem presentation of tuberculosis in an immunocompromised patient receiving long-term anti-CD20 therapy. Susceptibility was likely multifactorial, including immunosuppression, occupational exposure, MS-related immune dysregulation, and prior corticosteroid use. Clinicians should maintain a high index of suspicion for atypical tuberculosis in immunocompromised patients receiving biologic therapies.\n\nID: 42414010\nTitle: Guangxi Eco-Environmental Health and Aging Study (GEHAS).\nAbstract: The Guangxi Eco-Environmental Health and Aging Study (GEHAS) was established to investigate the interplay between eco-environmental exposome, multi-omics profiles, and healthy ageing in a multi-ethnic subtropical population. This prospective cohort was designed to address knowledge gaps regarding how eco-environmental and lifestyle factors influence ageing trajectories. GEHAS enrolled 5645 participants (59.8% women; mean age 62.51 years) from Guilin, Guangxi, at baseline, with Yao and Han participants accounting for 60.3% and 36.2% of the cohort, respectively. Baseline data (2018-2022) included questionnaires, physical examinations, biological specimens (blood, urine, hair and nails). Two subsequently established longevity and circadian rhythm sub-cohorts (n=276 and n=596) underwent multi-omics profiling (genomics, epigenomics, proteomics, metabolomics and exposomics). Follow-up in this open cohort includes active surveys approximately every 5 years and annual passive surveillance through government health registries. Recent analyses highlight that improvements in air quality can mitigate frailty progression in older adults, with DNA methylation emerging as a promising biomarker that captures the biological imprint of environmental policy interventions and ageing dynamics. In parallel, local specialty foods and traditional dietary practices have been implicated as potential contributors to reducing the risk of ageing-related diseases, as demonstrated by multiple studies using baseline data. For instance, oil tea consumption has shown potential protective effects against dyslipidaemia and type 2 diabetes, while region-specific dietary patterns were associated with favourable health outcomes in middle-aged and older adults. Specifically, a dose-dependent association was observed between diets rich in vegetables and mushrooms and enhanced cognitive performance, and antioxidant-rich dietary patterns were found to attenuate biological ageing through modulation of redox homeostasis. Moreover, GEHAS studies also explored the interactions between genetic factors and heavy metal exposures in age-related diseases, underscoring the complex interplay between genetic susceptibility and environmental influences in the ageing process. GEHAS will continue active follow-up surveys every 5 years, supplemented by annual passive surveillance for morbidity and mortality through health registries. The first active follow-up was initiated in 2023 and will continue until 2026/2027, with subsequent rounds planned thereafter. In addition, targeted sub-cohorts, including longevity and circadian rhythm groups, will undergo repeated assessments to capture long-term changes in health, exposures and biological ageing.\n\nID: 42406020\nTitle: Xenobiotics Induced Liver Toxicity.\nAbstract: Technological advancement and industrialization have significantly increased human exposure to xenobiotics, a diverse group of foreign chemical substances with potential toxic effects. Xenobiotics include pharmaceuticals, pesticides, personal care products, industrial chemicals, and environmental pollutants. The liver, as the primary organ responsible for biotransformation, plays a central role in the detoxification and activation of these compounds. However, metabolic processes may generate reactive intermediates that contribute to hepatocellular injury. This review provides a comprehensive overview of xenobiotic classification, mechanisms of hepatic biotransformation, and the molecular pathways underlying xenobiotic-induced hepatotoxicity. Special emphasis is placed on oxidative stress, reactive metabolite formation, and immune-mediated mechanisms. Clinical manifestations, diagnostic approaches, and current management strategies are also discussed. Understanding these processes is essential for early detection, prevention, and improved therapeutic outcomes in patients with xenobiotic-induced liver injury..\n\nID: 42385970\nTitle: Toxicity assessment of three emerging bisphenols (BPA, BPAP and BPC) and their binary mixtures in an advanced in vitro 3D HepG2 cell model.\nAbstract: Bisphenols (BPs) are industrial chemicals extensively used in polycarbonate plastics and epoxy resins for everyday products, including food and beverage containers, toys, and thermal paper, representing major sources of human exposure. Bisphenol A (BPA) is the most prevalent; however, due to its endocrine-disrupting, reproductive, and genotoxic effects, it is classified as a substance of high concern by the European Chemicals Agency. Regulatory restrictions have prompted the use of structural analogues, including bisphenol AP (BPAP) and bisphenol C (BPC); however, emerging evidence suggests they may pose similar or greater health risks. Comprehensive data on their toxicity and human exposure, especially in mixtures, remain limited. This study assessed the cytotoxic and genotoxic effects of BPA, and less studied analogues BPAP, BPC, and their binary mixtures using a human-relevant 3D HepG2 spheroid model, representing an advanced in vitro system. Spheroids were exposed for 24 and 96\u202fh, and effects were evaluated by ATP-based viability assays, comet assay, and targeted transcriptomics. None of the bisphenols induced significant cytotoxicity, although slight reductions in viability were observed for BPAP, BPC, and mixtures. DNA strand breaks were detected after exposure to BPA, BPC, and mixtures. Transcriptomic analysis revealed modest stress responses and strong upregulation of xenobiotic metabolism genes (CYP1A1, CYP1A2, CYP3A4, UGT1A1, NAT2), indicating cellular recognition of the tested bisphenols as bioactive xenobiotics. Antioxidant and DNA repair genes were largely unchanged, except for upregulation of oxidative stress markers HMOX1 and SRXN1 and a slight increase in OGG1, indicating oxidative DNA damage. Importantly, mixture effects were predominantly additive, with no evidence of synergistic interactions under the tested conditions. Overall, bisphenol exposure primarily triggered oxidative stress and metabolic responses rather than robust DNA damage signalling, suggesting that genotoxicity is largely mediated by reactive oxygen species. By integrating multiple endpoints in a 3D liver model, this study provides a more comprehensive assessment of bisphenol toxicity and highlights potential risks associated with BPA analogues and their mixtures, supporting the need for a comprehensive safety assessment to evaluate their suitability as replacements in consumer products.\n\nID: 42384431\nTitle: Gene-Environment Interactions in Childhood Asthma: From Prenatal Exposures to Targeted Interventions.\nAbstract: Asthma is one of the most common chronic respiratory diseases affecting both children and adults worldwide. Its pathogenesis is driven by complex interactions between genetic susceptibility and environmental exposures. Investigating gene-environment (G\u2009\u00d7\u2009E) interactions holds significant potential to elucidate the regulatory genetic architecture underlying individual responses to environmental risk factors in childhood asthma. In this review, we systematically summarize the environmental exposure factors during prenatal and postnatal periods and analyze their independent effects on the risk of childhood asthma. Secondly, we explore the role of G\u2009\u00d7\u2009E interactions\u00a0in asthma from three perspectives: statistical interaction, mechanistic interaction, and epigenetic-mediated interaction. Finally, we evaluate current treatment and intervention strategies, distinguish established recommendations for the general population from emerging and exploratory methods, and point out existing limitations. Our analysis reinforces that investigating G\u2009\u00d7\u2009E interactions is a robust approach for uncovering the molecular mechanisms underlying childhood asthma. Despite substantial technical challenges and unresolved questions regarding generalizability and heterogeneity, such investigative strategies are expected to enhance our understanding of asthma endotypes and the development of more effective, precision-based preventive and therapeutic interventions.\n\nID: 42352893\nTitle: Impact of Air Pollution on Metabolic Dysfunction-Associated Fatty Liver Disease.\nAbstract: Metabolic dysfunction-associated fatty liver disease (MAFLD) is now recognized as a leading form of chronic liver disease globally and is strongly associated with metabolic abnormalities. Traditionally, the pathogenesis of MAFLD has mainly been attributed to genetic susceptibility and unhealthy lifestyles (such as high-calorie diets and sedentary behavior). However, in recent years, environmental factors, especially air pollution, have been confirmed as independent risk factors and important promoting factors for MAFLD development and further disease progression. This review summarizes current epidemiological findings on the link between air pollution exposure and MAFLD, while exploring its potential biological mechanisms involving systemic inflammation, oxidative stress, immune alteration, genetic risk, and epigenetic regulation underlying the relationship between air pollution and hepatic steatosis. It also reviews the additive interaction between air pollution and lifestyle or socioeconomic factors in MAFLD. Finally, we also discuss multilevel strategies spanning individual-, community-, national-, and global-level cooperation to address the increasing public health burden caused by air pollution. Therefore, incorporating the assessment and control of air pollution into the comprehensive strategies for MAFLD prevention and treatment has important scientific value and public health significance.\n\nID: 42336260\nTitle: Acute or repeated exposure of aerosolized flame retardants induces molecular and structural alterations in lung slices.\nAbstract: Organophosphate flame retardants (OPFRs) such as tributyl phosphate (TBP) are widely used industrial additives increasingly detected in the environment and human tissues, yet their inhalation toxicity remains poorly characterized. In this study, we employed the ex vivo porcine precision-cut lung slice (pPCLS) model to investigate the cytotoxic, oxidative stress, and structural effects of aerosolized TBP under both acute and repeated exposure conditions. Using the Vitrocell\u00ae, pPCLS were exposed to TBP aerosols at deposited surface concentrations (\u00b5g/cm\u00b2) within ranges commonly applied in ALI-based inhalation toxicology models and selected to simulate cumulative low-dose exposure scenarios reported for organophosphate flame retardants in indoor environments. Acute exposure (24\u202fh) caused a reduction in tissue viability, increased reactive oxygen species (ROS) production, and enhanced caspase-3 activation, indicating mitochondrial stress and apoptosis induction. There is a potential tendency for markers (K-RAS, p53, and MMP-15) to increase. Histological analyses revealed disruption of extracellular matrix architecture. Repeated low-dose exposure (5\u202f\u00d7 24\u202fh) led to progressive tissue disorganization and early signs of fibrogenic remodeling, evidenced by increased collagen deposition, p53 expression, reduced tissue viability, and sustained oxidative stress. These findings suggest that cumulative subcytotoxic exposure to aerosolized TBP can initiate pathways associated with chronic pulmonary injury. The pPCLS model demonstrated high reproducibility, preserved lung architecture, and responsiveness to chemical insult, reinforcing its translational relevance for respiratory toxicology. Overall, our results provide mechanistic insight into TBP-induced lung toxicity and highlight precision-cut lung slices as a useful model for evaluating inhalation hazards of industrial chemicals.\n\nID: 42300269\nTitle: Nicotinic acid-catalyzed synthesis of novel benzothiazoles and benzimidazoles from carbohydrate-derived furfurals: structural, computational, and antimicrobial studies.\nAbstract: Benzothiazole and benzimidazole derivatives represent important heterocyclic scaffolds with well-established pharmacological relevance. In the present study, a sustainable synthetic approach was developed for the preparation of novel benzothiazole and benzimidazole derivatives via the condensation of carbohydrate-derived furaldehydes with 2-aminobenzenethiol and o-phenylenediamine, respectively. Various biogenic carboxylic acids were evaluated as catalysts, among which nicotinic acid exhibited superior catalytic efficiency, reusability, and compatibility with both aqueous and green organic solvents under conventional heating, affording the targeted products in excellent isolated yields (74-95%). The antimicrobial potential of the synthesized compounds was assessed using agar well diffusion and cup-plate methods against selected bacterial and fungal strains, revealing that several derivatives displayed significant inhibitory activity comparable to that of standard drugs. Two representative benzothiazole derivatives (4d and 4g) were further investigated by single-crystal X-ray diffraction to elucidate their molecular and supramolecular architectures. Density functional theory calculations based on experimentally determined geometries showed good electronic stability and comparable reactivity, while Hirshfeld surface analysis highlighted that the molecules in the crystal interact by hydrogen-bonding and \u03c0\u22ef\u03c0 interactions. Moreover, in silico ADMET studies indicated favorable drug-like properties and pharmacokinetic profiles, such as favorable oral absorption and moderate blood-brain barrier permeability.\n\nID: 42287544\nTitle: The Modern Environment and Childhood Asthma: The Role of Air Pollution and Heavy Metal Exposure.\nAbstract: Childhood asthma is the most common chronic non-communicable disease in children and a major global public health challenge. Although genetic predisposition contributes to asthma susceptibility, the high burden of disease-particularly in high-sociodemographic-index regions-points to a central role of environmental exposures characteristic of the modern environment. This review synthesizes current evidence linking ambient air pollution and heavy metal exposure to childhood asthma, with a focus on early-life vulnerability, underlying biological mechanisms, and implications for prevention. We reviewed epidemiological, toxicological, and mechanistic studies published through November 2025, prioritizing systematic reviews and meta-analyses while integrating recent cohort studies, intervention trials, and experimental research. Epidemiological findings consistently demonstrate that prenatal and early-childhood exposure to particulate matter (PM\u2082.\u2085, PM\u2081\u2080), traffic-related air pollutants (e.g., NO\u2082, black carbon), and ozone is associated with increased asthma incidence, wheezing, reduced lung function, and higher rates of exacerbations and healthcare utilization. In contrast, evidence for metal-related exposures is more heterogeneous. Toxic metals and metalloids, transition metals in particulate matter, and essential trace-element status may contribute to asthma risk through biologically plausible pathways, but associations appear to depend on exposure timing, exposure source, biomarker type, co-exposures, and population context. Mechanistic studies reveal shared and interacting pathways involving oxidative stress, airway epithelial barrier disruption, immune dysregulation, epigenetic modifications, and microbiome alterations. The effects of these exposures are magnified during critical developmental windows and modified by genetic susceptibility and social determinants of health, contributing to marked environmental health inequities. Overall, childhood asthma is strongly shaped by early-life exposure to air pollution and heavy metals through interconnected biological and social pathways. Addressing these preventable environmental risks is essential for effective asthma prevention and for reducing global disparities.\n\nID: 42281490\nTitle: Residential green space mitigates genetic susceptibility to incident irritable bowel syndrome in a prospective cohort of 376\u2009749 individuals.\nAbstract: Environmental exposures may influence irritable bowel syndrome (IBS) pathogenesis, but the interplay between genetic risk, residential green/blue space, and IBS incidence remains unexplored. We aimed to study the association between green/blue space and incident IBS, and to assess effect modification by genetic susceptibility. The study included 376\u2009749 UK Biobank participants at baseline. Residential green space was measured using the normalised difference vegetation index (NDVI), and blue space was defined by distance to the nearest water bodies. For time-to-event analyses, we used Cox proportional hazards models, polygenic risk scores (PRS), and mediation analysis to test gene-environment interactions. Results are presented as hazard ratios (HRs) with 95% confidence intervals (95% CIs). During a follow-up of 11.73 years, 7091 incident IBS cases were documented. Higher residential green space exposure was associated with reduced risk of incident IBS. Specifically, within a 1000 m buffer, each interquartile range (IQR) increase in NDVI corresponded to a 5% lower IBS risk (HR\u2009=\u20090.95; 95% CI\u2009=\u20090.91-0.98), with consistent effects observed at 800 m and 500 m buffers. Conversely, a greater distance to water bodies was associated with reduced IBS risk. Stratification by PRS revealed a significant interaction: increased green space (1000 m buffer) reduced IBS risk by 8% exclusively among high-genetic-risk individuals (HR\u2009=\u20090.92; 95% CI\u2009=\u20090.88-0.96), whereas no interaction was observed for blue space. Moreover, physical activity mediated the association between green space and IBS. Increased residential green space exposure is associated with reduced IBS incidence, particularly among individuals with high genetic susceptibility. These findings underscore the importance of urban greening as a public health strategy to mitigate IBS risk, highlighting the potential for targeted environmental interventions to offset genetic predispositions.\n\nID: 42259955\nTitle: Aging in a highly polluted world: challenges and solutions to prevent Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is the most prevalent neurodegenerative disorder globally and a leading cause of disability and death among the elderly. As populations age worldwide, the epidemiological burden of AD is expected to more than double by 2050, surpassing 150\u00a0million affected individuals. While genetic susceptibility, particularly the apolipoprotein E \u03b54 (APOE4) allele, modulates individual risk, most AD cases are late-onset and shaped by complex interactions between genetic background and modifiable environmental exposures. Environmental pollution has emerged as a critical and potentially preventable contributor to this burden. The 2024 Lancet Commission on Dementia Prevention, Intervention, and Care has identified 14 modifiable risk factors, with air pollution explicitly included. Drawing on evidence from human epidemiological cohorts, experimental animal models, and in vitro neuronal/glial systems, the present review aims to synthesize mechanistic evidence linking environmental pollutant classes to AD-relevant neuropathology. The review examines the growing body of evidence linking major categories of environmental pollutants (ambient particulate matter, heavy metals, pesticides, PFAS, and emerging contaminants including microplastics and nanoplastics) to AD risk and pathogenesis. Special attention is given to studies showing that the characteristic neuropathological features of AD may emerge in children and young adults chronically exposed to heavily polluted urban environments, which highlights critical concerns about when and how these changes develop throughout life. Shared mechanistic pathways through which environmental pollutants promote neurodegeneration are discussed, including neuroinflammation, oxidative stress, blood-brain barrier disruption, tau kinase dysregulation, epigenetic reprogramming, and gut-brain axis dysbiosis. The review also examines the amplifying role of biological aging on neurotoxic vulnerability and proposes a comprehensive, multi-level prevention framework addressing individual exposure reduction, clinical risk identification, and population-level policy interventions.\n\nID: 42259341\nTitle: Biological and mechanistic pathways of cardiometabolic multiple long-term conditions.\nAbstract: Cardiometabolic multiple long-term conditions (MLTC) arise from the complex interplay of biological, sociodemographic, environmental, and behavioural factors across the life course. Shared risk factors and mechanisms, including insulin resistance, adiposity, and chronic inflammation, underpin its development. Growing evidence also implicates that even low-level, long-term exposure to fine particulate matter, nitrogen dioxide, and related pollutants can accelerate the trajectory of cardiometabolic MLTC. Early-life exposures, including undernutrition and overnutrition, altered gut microbiome, and endocrine-disrupting chemicals, interact with social determinants of health to aggravate inflammatory and metabolic dysregulation. These mechanisms, together with genetic susceptibility, epigenetic modifications, and multiomics perturbations, shape disease progression, heterogeneity, and the clustering of cardiometabolic MLTC. Yet, fundamental gaps persist, whereby most mechanistic insights are derived from single-disease studies, leaving the temporal hierarchy, causal pathways, and population-level heterogeneity largely unresolved. Addressing these challenges will require life-course research, integrative systems approaches, and translational studies that link mechanistic insights to precision prevention and therapeutic strategies. By bridging discovery with actions, such efforts can enhance care for cardiometabolic MLTC and promote equitable health outcomes globally.\n\nID: 42248854\nTitle: Epidemiological and bioinformatics analyses of air pollution and genetic susceptibility in aortic stenosis risk.\nAbstract: While air pollution is a recognized cardiovascular risk, its specific impact on aortic stenosis (AS) remains poorly characterized. This study investigates the association between air pollution and incident AS, integrating gene-environment interactions and network toxicology. Based on the UK Biobank as the primary cohort, long-term air pollution exposure\u00a0(per standard deviation\u00a0increase) is associated with an increased risk of\u00a0AS, with HRs and 95% CIs of 1.60 (1.55,1.66) for PM2.5, 1.37 (1.32, 1.41) for PM10, 1.37 (1.32, 1.42) for NO2, and 1.36 (1.31, 1.41) for NOx. The observed associations demonstrate high consistency across a suite of advanced internal methodological validations and are further replicated in the Tianshan Community Cohort. There are joint and interactive effects of genetic susceptibility and air pollutants on AS risk. Network toxicology and bioinformatics analyses reveal key PM-AS target genes enriched in the lipid and atherosclerosis, fluid shear stress and atherosclerosis, and IL-17 signaling pathway. In conclusion, long-term exposure to PM2.5, PM10, NO2, and NOx is significantly associated with an increased AS risk, with a potential interaction between environmental exposure and genetic susceptibility.\n\nID: 42248381\nTitle: Prenatal cadmium exposure and behavioural and emotional problems across childhood: findings from the INMA birth cohort.\nAbstract: Prenatal cadmium (Cd) exposure may impair placental function and disrupt biological processes relevant to foetal neurodevelopment, including oxidative stress and metal homeostasis, but epidemiological evidence linking Cd to childhood behavioural and emotional problems remains inconsistent. We examined whether prenatal Cd exposure was associated with behavioural and emotional symptoms from early childhood to pre-adolescence in the Spanish INMA birth cohort. We included 1270 mother-child pairs from Valencia, Sabadell, and Gipuzkoa. Cd and creatinine were measured in maternal urine collected in the first and third trimesters of pregnancy, and average prenatal Cd exposure was analysed. Behavioural and emotional outcomes were assessed at ages 4-5, 7-8, 9, and 11 years using the ADHD-DSM-IV, Strengths and Difficulties Questionnaire, and Conners' Parent Rating Scales-Revised. Associations were estimated using multivariable negative binomial and mixed-effects models, with additional analyses for trimester-specific exposure, non-linearity, and effect modification by selected single nucleotide polymorphisms. Prenatal Cd exposure was not associated with any behavioural or emotional outcome across childhood. Results were also null when exposure was analysed separately for the first and third trimesters. In contrast, male sex and maternal smoking during pregnancy were consistently associated with poorer behavioural scores, whereas higher parental education and parity were generally associated with lower symptom levels. Interaction analyses indicated greater susceptibility among children whose mothers carried the MT1DP rs8044719 GT\u00a0+\u00a0TT genotype. In this population-based cohort, prenatal Cd exposure was not associated with behavioural or emotional problems across childhood. The findings nevertheless suggest that genetic susceptibility may contribute to interindividual differences in Cd-related neurodevelopmental vulnerability.\n\nID: 42199064\nTitle: Molecular mechanisms of environmental risk factors for interstitial lung disease.\nAbstract: Interstitial lung disease (ILD) comprises a diverse group of conditions characterized by lung inflammation and fibrosis. Cumulative lifetime exposures (i.e. the exposome) contribute to ILD onset and progression by interacting with genetic susceptibility and influencing multiple molecular pathways. This review summarizes current evidence evaluating how environmental exposures interact across the genome, epigenome, transcriptome, proteome, metabolome, and microbiome to drive ILD pathogenesis. Environmental exposures, including air pollution, influence ILD risk through interactions with genetic factors that modify disease susceptibility. Epigenetic mechanisms, particularly DNA methylation, reflect key pathways through which exposures may contribute to ILD onset and progression and serve as sensitive biomarkers of environmental injury. Exposure-associated molecular alterations can be detected across multiple omic layers, including transcriptomic, proteomic, and metabolomic profiles. In parallel, exposures like cigarette smoking, silica, and air pollution influence the respiratory microbiome, with potential downstream effects on immune responses and fibrogenesis. Integrating these findings highlights environmentally-sensitive pathways that may represent novel targets for therapeutic modulation. Integration of exposomic and multiomic molecular frameworks offers new opportunities to improve ILD risk stratification, prognostication, and precision therapeutic development, while also strengthening our mechanistic understanding of environmentally-mediated disease.\n\nID: 42198803\nTitle: Environmental Pesticide Exposure in the Etiology of Pediatric Brain Tumors and Leukemia: A Scoping Review of Epidemiological Studies.\nAbstract: Pediatric cancer is a significant cause of morbidity and mortality in children. The etiologies of pediatric cancer are largely\u00a0unknown, but environmental pesticide exposures are likely to contribute. Chronic low-dose exposure to pesticide mixtures through drinking water is a growing concern in agricultural communities. This review examines epidemiological studies published between January 1980 and September 2022 that have evaluated the relationship between pesticide exposure and the risk of childhood brain tumors and leukemia. Exposures to pesticides used in the home or ingested through drinking water, residential proximity to agricultural areas where pesticides are used, parental pesticide exposure, and metabolic genotypes are discussed. Findings have shown increased risks for childhood cancers in areas of high agricultural crop density, which may imply a link to increased pesticide applications and pesticide drift from neighboring farm fields.\u00a0Noted\u00a0knowledge gaps include the contribution of genetics, exposure through drinking water, individual-level exposures, and pesticide mixtures to the risk of pediatric cancer. Identifying distinctive genetic traits that influence the metabolism and detoxification of pesticide formulations, and their transformation products is crucial. This knowledge could inform preventive strategies and personalized interventions to reduce the burden of pediatric cancer and protect children's health.\n\nID: 42179068\nTitle: Environmental risk and genetic susceptibility in Alzheimer's disease: Impacts on cognitive function and biomarkers.\nAbstract: BackgroundAlzheimer's disease (AD) involves interactions among genetic, environmental, and lifestyle factors, yet the contribution of environmental exposures to cognitive decline and biomarker changes remains unclear. Detoxification genes such as EPHX1 may influence susceptibility to environmental neurotoxicants.ObjectiveTo evaluate associations between environmental risk, cognitive outcomes, and AD biomarkers, and to examine potential contributions of detoxification genes.MethodsWe analyzed 5101 participants from the Alzheimer's Disease Neuroimaging Initiative (ADNI) across four study phases. Environmental exposure was summarized using a composite Environmental Risk Score (ERS) derived from Rural-Urban Continuum Codes, Rural-Urban Commuting Area codes, Risk-Screening Environmental Indicators, and occupational exposure. Cognitive outcomes included Mini-Mental State Examination, Clinical Dementia Rating, Montreal Cognitive Assessment, Neuropsychological Test Battery, Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog), and Executive Dysfunction Cognitive Assessment. Biomarkers included PET amyloid/tau, MRI hippocampal volume, and cerebrospinal fluid amyloid-\u03b2, tau, and neurofilament light chain. Multivariable regression models adjusted for sociodemographic factors and APOE \u03b54 carrier status.ResultsERS was significantly associated with CDR (\u03b2\u2009=\u2009-1.13E-07; 95% CI -1.98E-07, -2.75E-08; p\u2009=\u20090.00956) but not with other cognitive measures. EPHX1 showed a significant main effect on ADAS-Cog (\u03b2\u2009=\u20090.479; 95% CI 0.0305, 0.927; p\u2009=\u20090.0356). ERS\u2009\u00d7\u2009gene interaction terms were not significant. ERS was not associated with amyloid PET SUVR.ConclusionsEnvironmental risk showed limited associations with AD-related outcomes, while EPHX1 demonstrated a significant main effect on cognitive performance. Longitudinal studies are needed to clarify mechanisms linking environmental exposure and AD.\n\nID: 42176051\nTitle: The Role of the Indoor Exposome in Food Allergy Development.\nAbstract: Due to the rapid rise in the prevalence of food allergy, environmental exposures, in addition to genetic susceptibility, are likely contributors to allergic disease. In developed countries, individuals spend a substantial proportion of time indoors. Therefore, the indoor exposome provides a unique framework to examine factors driving the increase in the rates of food allergy. This review summarizes epidemiological and mechanistic evidence of the indoor exposome, consisting of the combined exposures to food antigens, microbes, and chemicals encountered in indoor environments during early life, and their influence on food allergy development. Indoor house dust contains detectable food allergens, which remain biologically active and may be linked to non-oral exposure, leading to allergic sensitization. In contrast, early-life exposures to diverse microbes and their products are associated with protection from allergic disease. Emerging evidence further demonstrates that indoor chemicals, including detergents, plasticizers, and pollutants, can disrupt epithelial barrier integrity or function as immune adjuvants, thus increasing susceptibility to food sensitization. Collectively, these findings highlight the indoor exposome as a complex and important determinant of food allergy risk. Improved understanding of how the indoor exposome influences food allergy development may inform future primary prevention or intervention strategies.\n\nID: 42174808\nTitle: Environmental Personal Exposure Clusters to Investigate Multiple Sclerosis and Amyotrophic Lateral Sclerosis Progression.\nAbstract: Reliable prognosis in Multiple Sclerosis (MS) and Amyotrophic Lateral Sclerosis (ALS) is hampered by data scarcity and variability. Beyond clinical variables, evidence suggests that environmental data can help capture disease trajectories. We investigated whether personal environmental measures can be organized into stable patterns that inform prognosis. In a multicenter cohort, 293 patients with MS or ALS were equipped with Atmotube air-quality sensors. We normalized volatile organic compound (VOC) time series and computed Dynamic Time Warping distances to capture temporal similarity. Hierarchical clustering yielded five daily exposure clusters, which were profiled using Atmotube variables (season, day type, humidity, temperature) and patient self-reports (work status, time outdoors), and evaluated by day-level differences between personal and fixed-station variables. These clusters can support interpolation of missing wearable intervals and generation of context-aware exposure estimates, thereby strengthening environmental inputs for prognostic modeling in MS and ALS.\n\nID: 42136493\nTitle: Disruption of HOX Gene Regulation by Bisphenol A and Its Analogs: Epigenetic and Molecular Insights in Developmental Toxicity.\nAbstract: Bisphenol A (BPA), Bisphenol S (BPS), and Bisphenol F (BPF) are industrial chemicals with proven endocrine-disrupting activity. BPA, BPS, and BPF have estrogen-like activity and affect hormone action, leading to developmental toxicity. Recent data have proven that BPA, BPS, and BPF affect Homeobox (HOX) gene expression, which is crucial for development and organogenesis. An extensive literature survey was conducted using Google Scholar and PubMed, including literature published until 2025. The literature search was performed using various keywords like \"Bisphenol A,\" \"Bisphenol F,\" \"Bisphenol S,\" \"homeobox genes,\" \"epigenetic regulation,\" and \"developmental toxicity\". From the literature survey, it was clearly proven that BPA and its derivatives have a high impact if exposed during fetal development. Epigenetic changes in HOX gene clusters, changes in histone modification patterns, and increased oxidative stress levels are major areas of concern regarding developmental toxicity, which can affect fetal development, including neural development, sexual differentiation, and bone formation, all of which are crucial for embryogenesis and organogenesis. The literature review revealed that BPA and its derivatives, though claimed to be safer, are as toxic as BPA and, in some instances, are even more toxic to the developing fetus. The mechanistic action of bisphenols and the dysregulation of HOX gene expression are important steps towards understanding the teratogenic potential of BPA and its derivatives. BPA, BPF, and BPS are major concerns for embryonic development, as these chemicals affect the regulation of HOX gene expression and the signaling pathways that are crucial for embryonic development. Regulatory action and the development of safer chemicals are important for the health and safety of the fetus and for reducing the potential for developmental hazards.\n\nID: 42612798\nTitle: Dietary Exposure to Chromium and Barium in Shiraz, Iran: A Total Diet Study with Probabilistic Health Risk Assessment.\nAbstract: Dietary exposure to potentially toxic metals remains a significant public health concern. This total diet study quantified chromium (Cr) and barium (Ba) in foods commonly consumed in Shiraz, Iran, and evaluated the associated health risks. A total of 108 food items representing 20 food groups yielded 545 samples (540 food and 5 drinking water samples), which were analyzed by ICP-OES. Dietary intake was estimated using local consumption data, and health risks were assessed using hazard quotient (HQ), hazard index (HI), and total cancer risk (TCR) through Monte Carlo simulation (10,000 iterations). Mean Cr and Ba concentrations were 4.07 \u00b1 3.70 and 0.998 \u00b1 1.717 mg/kg, respectively. Chromium concentrations ranged from 0.68 to 10.61 mg/kg, with the highest levels in fish and fruits, while Ba concentrations ranged from 0.006 to 2.93 mg/kg and were highest in legumes and cereals. Fruits contributed the largest share of dietary Cr and Ba intake. Estimated daily intakes for a 72-kg adult were 0.12 and 0.022 mg/kg body weight/day for Cr and Ba, respectively, corresponding to 41.7% and 11.5% of the tolerable daily intakes established by EFSA and WHO. All HQ and HI values were below 1, indicating negligible non-carcinogenic risk, and screening TCR values for total Cr were within the acceptable range (10\u207b\u2076-10\u207b4). Although Cr concentrations in some foods exceeded typical background levels, overall dietary exposure remained below health-based guidance values. These findings provide baseline data for dietary exposure assessment and support continued surveillance of metal contamination in the food supply.\n\nID: 42606752\nTitle: Black carbon as a compound agricultural stressor: impacts on plant physiology, crop productivity, and agricultural sustainability.\nAbstract: Black carbon is an underappreciated compound agricultural stressor that simultaneously disrupts plant physiology, agroecosystem functioning, andcrop productivity, highlighting the need for realistic exposure assessment and integrated strategies for climate-resilient agriculture. Black carbon (BC), a carbonaceous particulate generated through the incomplete combustion of fossil fuels, biomass, and biofuels, is recognized as a major short-lived climate pollutant with significant implications for atmospheric processes and agricultural sustainability. Unlike engineered biochar, atmospheric BC acts as an environmental stressor through deposition on plant surfaces and accumulation in agroecosystems, yet its direct impacts on crop physiology remain insufficiently understood. This review synthesizes current knowledge on the physicochemical characteristics, environmental pathways, and plant stress mechanisms associated with atmospheric BC while explicitly distinguishing it from intentionally applied biochar. Available evidence indicates that BC influences plant performance through multiple interconnected pathways, including reduced light availability, stomatal obstruction, disruption of photosynthesis, oxidative stress induced by excessive reactive oxygen species (ROS), chloroplast dysfunction, hormonal imbalance, and alterations in nutrient cycling and soil microbial communities. However, much of the mechanistic evidence is derived from studies on biochar, carbon nanomaterials, or other particulate pollutants, highlighting a critical gap in plant-specific evidence under realistic atmospheric BC exposure. Regional studies, particularly from the Indo-Gangetic Plain, demonstrate that elevated BC and associated aerosol loading contribute to reduced crop productivity and increased food security risks, although these impacts often reflect the combined influence of multiple atmospheric stressors rather than BC alone. The review further examines current limitations in BC exposure quantification, emphasizing the absence of agronomic dose-response thresholds and standardized field-based assessment methods. Emerging approaches, including leaf-based biomonitoring and isotopic analyses, are discussed as promising tools for future exposure assessment. Finally, key research priorities are identified, including the generation of plant-specific mechanistic evidence, development of realistic dose-response frameworks, integration of BC into crop simulation models, and implementation of long-term field studies to improve risk assessment and support evidence-based mitigation strategies for sustainable agriculture.\n\nID: 42605854\nTitle: Rosemary extract (E392) in main Chinese foods and associated health risk.\nAbstract: This study assessed the application of rosemary extract (E392) in foods and estimated dietary exposure in China, using a stepwise approach, encompassing theoretical maximum use, enterprise-reported usage, and product-level monitoring. Exposure assessments combined national dietary survey data, regulatory limits, industry reports, and surveillance findings. Under the theoretical maximum scenario, estimated daily intake (EDI) approached the temporary acceptable daily intake (tADI) of 0.3\u2009mg/kg bw/day, with P95 values exceeding it 1.5-1.9 times, indicating potential risk for high-intake subgroups. In contrast, enterprise-reported and monitoring scenarios yielded EDI values well below the tADI, suggesting negligible risk under typical conditions. Marinated meats, animal fats and compound seasonings were the primary contributors to exposure. Rosemary components were also detected in non-authorised food categories, implying possible carry-over effects. Overall, current use patterns appear safe, but improved additive traceability and targeted surveillance are needed to refine exposure assessments and support enforcement of regulation.\n\nID: 42595120\nTitle: Higher Maternal Serum Alkyl-substituted Organophosphate Ester Concentrations at 9 to 13+6 Gestational Weeks Are Associated with Increased Birth Weight and Large-for-Gestational-Age Risk: A Prospective Cohort Study.\nAbstract: Evidence linking maternal organophosphate ester (OPE) exposure during early gestational weeks with infant birth weight outcomes remains limited. This prospective cohort study examined associations of maternal serum OPE concentrations at 9 to 13+6 gestational weeks with infant birth weight, large for gestational age (LGA), and small for gestational age (SGA). Among 1, 039 pregnant females in a Qingdao birth cohort, 16 serum OPEs were measured using gas chromatography-tandem mass spectrometry (GC-MS/MS). Individual OPEs were evaluated per interquartile-range increase in ln-transformed concentration using multivariable linear regression and modified Poisson regression. Quantile g-computation (Qgcomp), weighted quantile sum (WQS) regression, and Bayesian kernel machine regression (BKMR) assessed OPE mixtures. Tris(isobutyl) phosphate (TIBP) and tris(2-ethylhexyl) phosphate (TEHP) were associated with higher birth weight [TIBP: \u03b2 = 77 g, 95% confidence interval (CI): (37, 117); TEHP: \u03b2 = 40 g, 95% CI: (18, 63)]. TEHP was associated with higher LGA risk [adjusted risk ratio (aRR) = 1.27, 95% CI: (1.09, 1.48)] and lower SGA risk [aRR = 0.71, 95% CI: (0.57, 0.90)]; p-cresyl diphenyl phosphate (pCDP) was also associated with lower SGA risk [aRR = 0.69, 95% CI: (0.53, 0.91)]. In Qgcomp models, total OPE mixture exposure was associated with higher LGA risk [aRR = 1.41, 95% CI: (1.10, 1.80)]. Alkyl-substituted OPE mixture was associated with higher LGA risk in Qgcomp and higher birth weight in WQS; halogenated OPE mixture showed no significant associations. Maternal serum concentrations of selected OPEs at 9 to 13+6 gestational weeks, particularly alkyl-substituted OPEs, were associated with higher birth weight and LGA risk. These findings warrant confirmation in studies with repeated exposure assessment and additional longitudinal fetal growth indicators.\n\nID: 42579094\nTitle: Fluorinated Liquid Crystal Monomers in Human Urine: Occurrence, Demographic Associations, and Health Risk Assessment in a Cohort of 150 Couples.\nAbstract: Fluorinated liquid crystal monomers (FLCMs) represent an emerging class of environmental contaminants characterized by persistence, bioaccumulation potential, and suspected toxicity; however, knowledge of exposure profiles and associated health risks in the general population remain inadequate. This study systematically investigated the occurrence of 50 FLCMs in 300 urine samples collected from 150 couples living in Tianjin, China. Among the 50 target analytes, 42 were detected, with total FLCM concentrations (\u2211FLCMs) ranging from 1.59 to 34.60 ng/mL (median: 7.45 ng/mL), which were substantially higher than reported urinary levels in Beijing and Guangdong populations. The predominant compounds identified were DTMTPT (4-[difluoro(3,4,5-trifluorophenoxy)methyl]-2',3,5-trifluoro-4'-pentyl-1,1':4',1'-terphenyl), CFPEB (3-fluoro-4-cyanophenyl 4-ethylbenzoate), EDPBB (1-ethoxy-2,3-difluoro-4-[(trans,trans)-4'-propyl[1,1'-bicyclohexyl]-4-yl]benzene), DPPCB (2,3-difluoro-1-propoxy-4-[(trans,trans)-4'-propyl[1,1'-bicyclohexyl]-4-yl]benzene), and EFPT (4\u2033-ethyl-2'-fluoro-4-propyl-1,1':4',1\u2033-terphenyl), with DTMTPT and CFPEB representing the largest contributions at 20.5% and 19.1% of total concentrations, respectively. Demographic analysis revealed that urinary EFPT concentrations were significantly lower in females than in males (P < 0.05), and gender exerted a more pronounced influence on exposure than cohabitation. Individuals aged <30 years exhibited marginally elevated FLCM exposure compared to those \u226530 years, whereas body mass index, smoking status, and alcohol consumption showed no significant associations with urinary FLCM concentrations (P > 0.05). Correlation analysis and molecular docking simulations demonstrated that CFPEB and DTMTPT were significantly positively correlated with serum alanine aminotransferase levels (P < 0.05), and all five major FLCMs exhibited stable binding affinities to the aryl hydrocarbon receptor (AhR), suggesting potential hepatotoxicity. Screening-level hazard quotient (HQ) assessment indicated low health risks under current exposure scenarios. This study addresses a critical data gap regarding FLCM exposure in the general adult population of China and provides foundational data and scientific evidence for characterizing human exposure patterns and informing risk management strategies for this emerging contaminant class.\n\nID: 42565883\nTitle: Seasonal dynamics of trace elements, sediment contamination, and child health risks in six Egyptian red sea ports: an integrated water-sediment-human health assessment.\nAbstract: Coastal port environments along the Red Sea-Suez Canal corridor face intensifying multi-stressor pressures, yet integrated seawater-sediment-human-health assessments of toxicologically distinct trace elements remain scarce. In this study, arsenic (As), selenium (Se), tin (Sn) and mercury (Hg) were quantified in surface seawater (n\u2009=\u200938) and surficial sediments (n\u2009=\u200919) across six Egyptian ports (Port Tawfiq, Zayteiat, Hurghada, Safaga, Nuweibaa and Sharm El-Sheikh). Six contamination and ecological-risk indices (CF, Igeo, PLI, MPI, Er and RI) were integrated with a USEPA-compliant human health risk assessment and multivariate source apportionment to disentangle natural and anthropogenic signatures. Dissolved As exhibited a pronounced and biogeochemically coherent seasonal inversion, with winter concentrations (8.82\u2009\u00b1\u20091.04\u00a0\u00b5g\u00a0L-1) 3.2-fold higher than summer values (2.76\u2009\u00b1\u20090.53\u00a0\u00b5g\u00a0L-1; p\u2009<\u20090.001), whereas Se followed the opposite trend (summer\u2009>\u2009winter; p\u2009<\u20090.001). All stations fell within the \"low\" ecological-risk category, with sediment-based indices uniformly low (PLI\u2009=\u20090.07-0.47; RI\u2009=\u20093.6-22.4). Critically, non-carcinogenic hazard indices for children exceeded unity at all six ports (HI\u2009=\u20091.13-1.57), driven predominantly (>\u200992%) by As, an exceedance that would be masked by adult-only assessment (HI\u2009=\u20090.50-0.67). Total carcinogenic risk remained within the acceptable 10-6-10-4 range. Principal component analysis and inter-element correlations (r\u2009\u2265\u20090.84, p\u2009<\u20090.001) resolved two anthropogenic clusters: a legacy antifouling-paint (Sn-As-Hg) signature at high-traffic ports persisting over a decade after the 2008 IMO organotin ban, and petroleum-related Se enrichment at the Zayteiat oil terminal. These findings highlight the necessity of age-stratified exposure assessment and sustained multi-compartment monitoring as Suez Canal traffic intensifies.\n\nID: 42556775\nTitle: Updating aggregate consumer exposure assessment for cosmetics and personal care products: Phase IV of the Creme RIFM aggregate exposure model.\nAbstract: Exposure assessment is a critical component of fragrance safety evaluation and risk assessment. The Creme RIFM Aggregate Exposure Model is a probabilistic framework that estimates aggregate consumer exposure to fragrance ingredients in cosmetics and personal care products across dermal, inhalation, and oral routes. A key feature of the model is the ability to update consumer habits and practices data while maintaining a consistent assessment methodology. Phase IV incorporates Kantar Worldpanel consumer diary data collected throughout 2023, replacing the 2014-2015 dataset. The updated database includes 37,165 participants aged 11-79 years from the United States and five European countries. Integration of the new data required refinements to product categorization, product mapping, application-site assignment, and the addition of previously unrepresented product categories. Comparison of exposure estimates from the two datasets showed that consumer use patterns remained largely consistent. Differences were mainly attributable to methodological refinements, improved product mapping, changes in regional population coverage resulting from the exclusion of Italy in the 2023 dataset, and inclusion of new product categories. Overall, the update strengthens the model's relevance, robustness, and utility for fragrance safety and exposure-based risk assessment.\n\nID: 42556389\nTitle: A narrative review of cancer risks in medical radiation workers across high- and low-dose practice eras: implications for radiation protection.\nAbstract: Medical radiation workers constitute the largest occupational group exposed to man-made ionising radiation, yet much of the evidence on cancer risk derives from early high-dose practice eras that differ substantially from contemporary conditions. This narrative review synthesises evidence from cohort studies of medical radiation workers across occupational exposure eras, with emphasis on epidemiologic approaches, observed cancer risk patterns, and sex-specific differences. Epidemiologic methods have evolved from proxy-based exposure indicators to quantitative dose-response modelling using excess relative risk, supported by improved dosimetry and organ-dose reconstruction. Early high-dose cohorts consistently demonstrate elevated risks for radiosensitive cancers, including breast cancer, haematopoietic malignancies, and non-melanoma skin cancer. In contrast, contemporary cohorts exposed under current protection standards accumulate low cumulative doses and show small, often non-significant dose-response estimates with wide confidence intervals. These findings reflect both reductions in occupational exposure and the limited statistical power of epidemiologic studies at low dose levels, where excess risks are difficult to detect and dose-response shape cannot be clearly distinguished. Available evidence does not indicate consistent sex-based differences in radiation-related cancer risk at occupational exposure levels. Overall, while advances in dosimetry have improved exposure assessment, the ability to quantify cancer risk under contemporary low-dose conditions remains constrained. The findings support the effectiveness of current radiation protection practices while highlighting persistent uncertainty in estimating risks at low occupational doses.\n\nID: 42554254\nTitle: Inhaled aerosol dosimetry update.\nAbstract: To evaluate recent advances and current challenges in inhaled aerosol dosimetry research, with a focus on understanding how particles affect human health through deposited doses, and to identify key research needs for improving exposure assessment and risk evaluation. The findings were based on discussions and presentations from the Fourth International Aerosol Dosimetry Conference held in 2024 in Irvine, California. The conference used plenary sessions to promote cross-disciplinary communication and collaboration. Topics included computational models and simulations, in vitro and in vivo aerosol exposure systems, and variability in inhaled aerosol deposition. State-of-the-art research was presented, followed by open discussions to identify knowledge gaps and future priorities. Significant advances were reported in computational modeling, particularly in integrating different model types to better represent all major regions of the respiratory tract. Improvements in in vitro exposure systems enhanced particle delivery, dose measurement, and applicability to human health studies. Research also highlighted the importance of the upper airways as entry routes for inhaled medications. Dose variability emerged as a critical issue across aerosol dosimetry studies. New findings showed that inhaled ultrafine particles may acquire surface coatings after deposition and can penetrate tissues, including fetal tissues. Standardization and validation of in vitro approaches were identified as essential steps for reducing reliance on animal testing and improving human risk assessment. Internal aerosol dosimetry research continues to advance through improved models, exposure systems, and mechanistic understanding of deposited particle behavior. However, addressing dose variability, standardizing alternative testing methods, and improving data sharing remain essential for advancing risk assessment and supporting more accurate evaluations of inhaled particle effects on human health.\n\nID: 42541686\nTitle: Fatty Acid Profile, Mineral Composition and Heavy Metal Contamination in Brown Bear (Ursus arctos) Muscle: Implications for Human Health Risk Assessment.\nAbstract: This study evaluated the proximate composition, fatty acid profile, mineral composition, and heavy metal contamination of brown bear (Ursus arctos) muscle, with emphasis on its nutritional quality and potential health risks for consumers. Muscle samples (musculus semimembranosus and musculus triceps brachii; n\u2009=\u200910) obtained from free-ranging individuals in Slovakia were analysed using validated analytical methods. Brown bear muscle was characterised by high protein content (~\u200922.5\u00a0g/100\u00a0g) and low intramuscular fat content (<\u20091\u00a0g/100\u00a0g), confirming its lean nutritional profile. The fatty acid composition was dominated by monounsaturated fatty acids, followed by saturated and polyunsaturated fatty acids. Lipid quality indices indicated favourable nutritional properties, including low atherogenic and thrombogenic indices and a PUFA/SFA ratio above recommended nutritional thresholds. However, the relatively high n-6/n-3 ratio reflected the omnivorous feeding ecology and seasonal physiological status of the analysed animals. Iron and zinc represented the predominant trace minerals, highlighting the nutritional value of the analysed muscle tissue. Most toxic elements (As, Cr, Cd, Hg) remained below analytical detection or quantification thresholds and were therefore interpreted descriptively. Lead (Pb) was detected at low mean concentrations; however, substantial inter-individual variability resulted in sporadically elevated values, most likely associated with secondary contamination from bullet fragments. Exposure assessment based on consumption of a 100\u00a0g portion and an upper-bound approach for left-censored data indicated negligible toxicological relevance for Cd and Hg, whereas Pb exposure increased considerably under maximum exposure scenarios. Overall, brown bear muscle represents a nutritionally valuable food source; however, continued monitoring of Pb contamination in game meat remains warranted.\n\nID: 42540253\nTitle: Health Risk Assessment of Dietary Arsenic Exposure and Selenium Deficiency in Tibet Based on In Vitro Gastrointestinal Simulation.\nAbstract: The Tibetan Plateau has a distinctive high-As and low-Se geochemical background. This geochemical characteristic can be transferred to the human body via food intake, thereby posing potential health risks. Conventional assessments based only on total elemental concentrations may not reflect the fraction released during gastrointestinal digestion. In this study, the Unified Bioaccessibility Method (UBM) was combined with Monte Carlo simulation to evaluate dietary As exposure and Se intake from typical Tibetan foods. The results showed a low dietary Se/As ratio of 0.80, far below the national average of 4.35. Bioaccessibility-adjusted modeling reduced estimated As exposure, but carcinogenic risk remained above 10-4 in all age groups, with the highest mean risk in children. Estimated Se intake was also below the recommended level. After simulated gastrointestinal digestion, the As-Se correlation increased from r = 0.40 to 0.58, indicating a stronger postdigestion association. These findings highlight the need to incorporate bioaccessibility into dietary exposure assessment and suggest that Tibetan populations may face both elevated As-related risk and insufficient Se intake.\n\nID: 42531978\nTitle: Long-term exposure to outdoor artificial light-at-night and its associations with natural-cause and cause-specific mortality: a register-based cohort study in the Netherlands.\nAbstract: Outdoor artificial light-at-night (ALAN) is increasingly recognized as a potential environmental health risk. Epidemiological evidence mainly comes from incidence studies, whereas cause-specific mortality, reflecting disease occurrence and survival, has rarely been examined.Estimated associations may depend on the scale of ALAN exposure assessment, including grid-level and buffer-based measures. We aimed to (1) assess the associations between long-term ALAN exposure and natural-cause and cause-specific mortality; (2) evaluate the sensitivity of these associations across various spatial scales of the ALAN assessment; and (3) examine whether some socio-demographic population groups are more vulnerable. We conducted a register-based cohort study of 6,325,139 adults in the Netherlands (2013-2023). We linked satellite-derived average ALAN exposure over 2013-2023 to residential addresses using 50-m grid values and 300-1,000\u00a0m buffers. Mortality included natural causes, cerebrovascular disease (CeVD), coronary heart disease (CHD), type 2 diabetes (T2D), obesity, breast cancer (BC), and prostate cancer (PCa). Associations were estimated using Cox proportional hazards models adjusted for individual-level characteristics and environmental exposures, with effect modification assessed via interaction terms and stratification. ALAN exposure was positively associated with natural-cause mortality and with mortality from T2D, obesity, BC, and PCa. The most robust association was for T2D (HR\u00a0=\u00a01.06, 95% CI: 1.02-1.10) and obesity (HR\u00a0=\u00a01.07, 95% CI: 1.00-1.15). Associations for BC and PCa were positive only after adjusting for environmental exposures. No associations were found for CHD or CeVD mortality. Estimates were attenuated with larger buffers. Stronger associations were observed among middle-aged adults, those with low and middle levels of education, low-income groups, women, non-Dutch, and non-cohabiting populations. Long-term ALAN exposure was associated with metabolic-cause mortality (notably T2D), with stronger associations in some socio-demographic groups, suggesting differential vulnerability. Effect estimates varied with the spatial scale of exposure assessment and with adjustment for other environmental exposures.\n\nID: 42528337\nTitle: Mathematical Modeling of Viral RNA Copies in Indoor Environments: Pre-Processor for Risk Assessment and Decision-Making Support Tool for Public Health.\nAbstract: Quantifying human exposure to airborne respiratory viruses is essential for infection risk assessment modeling and evidence-based infection control policies. However, accurate size and time resolved estimates of airborne viral RNA copies in indoor spaces are often hindered by existing models that compress complex droplet physics into too simplified processes. Therefore, we present a size-resolved framework that couples saliva-specific evaporation and residue formation with gravitational settling to compute airborne viral RNA covering 1-2000 \u00b5m under varied temperature, relative humidity, and ambient pressure (101.325 and 75.3\u00a0kPa). Our framework also combines particle volume contribution considering saliva mass uncertainty, viral load, viral half-life, exhalation mechanisms (talking, coughing, sneezing), and ventilation effects. Under literature-based half-life inputs and volume-proportional RNA allocation, viral load and size-resolved airborne lifetime dominated the simulated RNA-copy trends, although the role of viral half-life may vary if RNA decay differs from infectivity decay or if viral RNA concentrates in long-suspended fine aerosols. Talking dominates persistence of airborne RNA copies since coughing and sneezing produce larger droplets that settle quickly. Also, model predictions are compared with hospital air-sampling datasets. The 50-percentile of saliva mass provides the closest match, with most samples falling within roughly one order of magnitude and central tendency close to unbiased. Our model is designed to serve as (1) pre-processor that supplies inputs for infection-risk assessment modeling studies and (2) decision-making support tool, facilitating public-health intervention. Therefore, we also provide an online web tool that allows users to directly adjust inputs and immediately analyze scenario-specific outcomes.\n\nID: 42526759\nTitle: Antimicrobial and Pesticide Residues in Animal-Source Foods in Bangladesh: A Meta-Analysis with Probabilistic Dietary Exposure and Health-Risk Assessment.\nAbstract: Intensifying livestock, poultry and aquaculture production in Bangladesh has been accompanied by unregulated antimicrobial and persistent organochlorine pesticide use, yet no national synthesis has linked residue occurrence in animal-source foods (ASFs) to consumer health risk. This study aimed to pool the prevalence and concentration of antimicrobial and pesticide residues in Bangladeshi ASFs and to estimate dietary exposure and risk using deterministic and probabilistic frameworks benchmarked against health-based guidance values. Following PRISMA 2020, five databases were searched from January 2010 to April 2026. Random-effects models (Freeman-Tukey transformation, DerSimonian-Laird estimator) pooled prevalence across five matrices. Estimated daily intakes were combined with national consumption data and JECFA/JMPR acceptable daily intakes (ADIs) to derive hazard quotients (HQs), a cumulative hazard index (HI) and margins of exposure (MOE); a 10,000-iteration Monte-Carlo simulation characterized high-consumer (P95) exposure. Thirty-five studies (5,255 samples) were analyzed. Pooled prevalence was 12.9% (95% CI 8.8-17.6; I2\u00a0=\u00a095.8%), highest in farmed fish (40.3%) and lowest in eggs (4.7%); tetracyclines, fluoroquinolones, and organochlorines predominated. For the average adult, all HQs were \u226a1 and the cumulative HI was 0.031; heptachlor and dieldrin dominated (P95 %ADI 6.2 and 4.7). The child HI (\u22480.062) remained below unity; chloramphenicol P95 MOE fell to 253. Central-tendency dietary risk is low, but high-consumer tails, cumulative exposure, prohibited-substance detection and small-study effects justify strengthened, Codex-aligned residue surveillance, withdrawal-period enforcement and risk-based national monitoring within a One-Health framework.\n\nID: 42516962\nTitle: Setting of import tolerance for folpet in bananas and modification of the existing maximum residue level in honey.\nAbstract: In accordance with Article 6 of Regulation (EC) No 396/2005, the applicant ADAMA Agriculture BV submitted a request to the competent national authority in Austria to set an import tolerance for the active substance folpet in bananas. Within the submitted application the applicant requested as well to modify the existing maximum residue level (MRL) for folpet in honey. The data submitted in support of the requests were found to be sufficient to derive an MRL proposal for bananas according to the current residue definition for enforcement. For honey however, the submitted trials were not compliant with good agricultural practice (GAP) and therefore not appropriate to derive an MRL proposal. Adequate analytical methods for enforcement, based on liquid and gas chromatography, are available to quantify residues of folpet and phthalimide in bananas and honey with lowest validated limit of quantification (LOQ) of 0.01 mg/kg (both compounds). Based on the risk assessment results, EFSA concluded that the short-term and long-term intake of folpet residues expected in bananas and honey is unlikely to present a risk to consumer health. However, uncertainties remain regarding the long-term exposure assessment due to missing residue data for phthalamic acid (in root crops) and phthalic acid (in all commodities except bananas and honey).\n\nID: 42515196\nTitle: Spatial Distribution Characteristics and Human Health Risk Assessment of Organophosphate Esters in Indoor Dust in Beijing.\nAbstract: Organophosphate esters (OPEs), extensively employed as flame retardants and plasticizers, have emerged as ubiquitous contaminants in indoor environments following the phase-out of brominated flame retardants. However, the occurrence patterns, source characteristics, and exposure implications of emerging OPE congeners across diverse urban indoor microenvironments remain inadequately elucidated. In this study, twenty-eight OPE congeners were quantified in settled dust collected from eight representative indoor microenvironments and one outdoor reference site in Beijing, China. Total OPE concentrations exhibited pronounced spatial heterogeneity, ranging from 8.46 to 42.60 mg kg-1, with the highest levels observed in subway stations and laboratories. Non-halogenated OPEs dominated the contamination profile, accounting for 80.7% of the total OPEs, whereas Tris(2-ethylhexyl) phosphate (TEHP), 2-Ethylhexyl diphenyl phosphate (EHDPP), Tris(1-chloro-2-propyl) phosphate (TCIPP), Tris(2-chloroethyl) phosphate (TCEP), and Triphenyl phosphate (TPhP) collectively contributed 85.1% of the overall burden. Correlation analysis and positive matrix factorization revealed that indoor OPE contamination was primarily associated with emissions from building materials, polymer-containing consumer products, furniture, and electronic equipment. Transformation-associated compounds such as Bis(2-butoxyethyl) hydroxyethyl phosphate (BBOEHEP) were detected in indoor dust, pointing to the plausible presence of OPE transformation processes in such enclosed settings. Exposure assessment demonstrated that dust ingestion accounted for over 98% of total OPE intake, resulting in substantially higher exposure levels in children than in adults. Although estimated non-carcinogenic and carcinogenic risks remained below established health-based thresholds, exposure was disproportionately driven by a limited number of congeners, particularly EHDPP, TCIPP, TCEP, and TEHP. These findings highlight the growing contribution of replacement OPEs to indoor chemical burdens and underscore the importance of incorporating transformation products and indoor aging processes into future exposure and risk assessments frameworks.\n\nID: 42515149\nTitle: Pilot Multi-Matrix Biomonitoring of Mixed Mercury Exposure Pathways Among E-Waste Dismantling Workers in South China.\nAbstract: Informal electronic-waste (e-waste) dismantling can mobilize mercury (Hg) from Hg-containing components and contaminated dust, while local diet can contribute methylmercury (MeHg), creating a mixed environmental exposure setting for human biomonitoring. This pilot study integrated paired biomarkers, local foods, work and indoor dust, Hg speciation and hair Hg isotope signatures among 18 e-waste dismantling workers in Qingyuan, South China. Total Hg (THg), MeHg and inorganic Hg (IHg) were measured in hair, blood and foods; urine and dust were analyzed for THg; and hair \u03b4202Hg, \u0394199Hg and \u0394201Hg were determined. Median THg was 403 \u03bcg/kg in hair, 1.60 \u03bcg/L in blood and 0.438 \u03bcg/L in urine. Fish showed the highest food THg, whereas work and indoor dust had the highest matrix concentrations. Hair was MeHg-dominant but contained substantial IHg, and \u0394199Hg values were positive but modest. The integrated patterns support mixed dietary MeHg and non-dietary IHg contributions and identify exposure-pathway priorities for future biomonitoring and source-focused studies.\n\nID: 42511219\nTitle: Seafood-Linked and Sex-Specific Signatures of Legacy and Emerging PFAS Body Burden During Dietary Transition in Sichuan, China.\nAbstract: Per- and polyfluoroalkyl substances (PFASs) are persistent contaminants of concern in food safety and human exposure assessment. Aquatic foods are important components of dietary diversification, but their association with internal PFAS burden remains unclear in inland populations. Of the 1294 participants initially recruited, 1292 with complete demographic information were included in the final analyses. Serum concentrations of 22 PFASs were measured by solid-phase extraction coupled with UPLC-MS/MS, and nine PFASs detected in more than 75% of samples were analyzed. Dietary intake frequency, sociodemographic characteristics, and lifestyle factors were collected using structured questionnaires. Multivariable linear regression and sex-stratified analyses were performed. Seafood-related food groups showed the most consistent positive associations with serum PFAS levels. Frequent consumption of shellfish, shrimp, crabs, fish, and seaweed was associated with higher concentrations of long-chain PFASs, including PFDA, PFNA, PFHxS, PFOS, and PFOA, while shrimp and crab intake was also positively associated with 6:2 Cl-PFESA. These associations were generally stronger in males, suggesting sex-related heterogeneity in the relationship between seafood intake and PFAS body burden. These findings suggest that seafood consumption is associated with distinct PFAS body-burden profiles in inland adults and may support integrated biomonitoring, dietary assessment, and food-contaminant surveillance.\n\nID: 42508118\nTitle: Bridging analytical gaps in perchlorate monitoring: a comprehensive study of food contamination and exposure risk in Spain.\nAbstract: Perchlorate is an emerging contaminant that can impair neurological development by disrupting thyroid function. Diet intake, particularly teas, fruits, and vegetables, is a major exposure pathway. This study developed a rapid, highly sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) method applicable to all regulated food categories. The method's high sensitivity is essential, as it improves dietary exposure assessment and reduces uncertainties in risk evaluation, particularly for vulnerable populations. The method was validated with satisfactory recoveries (71-109%). A total of 115 food samples were analysed, including 28 infant food samples, a category notably underrepresented in European datasets. Perchlorate was detected in 95.7% of samples, with concentrations exceeding the European Union (EU) maximum limit in four cases. Risk assessment showed that infants and toddlers are especially vulnerable, with a Hazard Index, exceeding the safe limit of 1.\n\nID: 42506714\nTitle: Overview of Current Regulatory and Methodological Approaches for the Risk Assessment of Mycotoxins.\nAbstract: Risk assessment is a dynamic and continuously evolving process aimed at characterizing the potential adverse effects on life and health arising from exposure to hazards. Among these hazards, mycotoxins represent one of the most significant and widely investigated contaminants in food and feed. This review aims to summarize current knowledge on mycotoxin risk assessment practice, both for single substances and for cumulative risk assessment, and to provide practical guidance for future researchers. As individual substances, mycotoxins are well characterized from a toxicological perspective, and numerous risk assessments have been conducted globally across a wide range of food products. Although well-established methodological frameworks exist to support the cumulative risk assessment of mycotoxins, further efforts are needed to define common assessment groups, especially considering the pleiotropic nature of these compounds.\n\nID: 42495791\nTitle: Microplastics and nanoplastics in humans: exposure pathways, biological mechanisms, and implications for health risk assessment.\nAbstract: Microplastics (MPs) and nanoplastics (NPs) are ubiquitous contaminants, but their implications for human internal exposure, biological effects, and health risk assessment remain incompletely defined. Although many reviews summarize environmental occurrence and ecological impacts, fewer integrate human exposure pathways with mechanistic toxicological evidence and safety-relevant uncertainties. This review synthesizes evidence on inhalation, ingestion, and dermal exposure, emphasizing particle size, barrier interactions, translocation, and distribution. We examine experimental and clinical evidence describing oxidative stress, inflammatory signaling, epithelial barrier dysfunction, gut dysbiosis, immune activation, and endocrine interference associated with MP and NP exposure. Particular attention is given to distinguishing MPs from NPs in terms of cellular uptake, biodistribution, analytical detectability, and toxicodynamic behavior. We also discuss limitations in exposure assessment, including contamination bias, analytical detection limits, and harmonized reporting standards. Rather than focusing on environmental prevalence, this review highlights gaps in exposure quantification, dose-response relationships, chronic low-dose exposure, vulnerable populations, and co-exposure to plastic additives or adsorbed contaminants. An organ-specific risk perspective is integrated, emphasizing respiratory, digestive, immune, and systemic effects, as well as particle size, polymer type, exposure concentration, and human dose-response uncertainty. By synthesizing toxicological, analytical, and public health evidence, this review defines research priorities for risk assessment.\n\nID: 42481871\nTitle: Stuffed toys as a source of oral PFAS exposure: Migration into artificial saliva and exposure assessment.\nAbstract: Per- and polyfluoroalkyl substances (PFAS) are widely used in textiles and consumer products, resulting in ubiquitous human exposure. Infants and young children may experience distinct exposure patterns due to mouthing behavior, yet oral exposure from textile-based products such as stuffed toys remains poorly characterized. This study aimed to quantify saliva-mediated PFAS migration from commercially available stuffed toys under mouthing-relevant conditions, assess the potential contribution to early-life exposure, and evaluate the effectiveness of washing as a mitigation measure. Eighteen stuffed toys intended for infants and toddlers were analysed. PFAS migration was assessed using artificial saliva under standardized conditions and quantified by Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS). Deterministic exposure assessment was performed to estimate daily and weekly intake, complemented by margin of exposure (MOE) calculations and reverse dosimetry based on biomonitoring data. The effect of a standardized water-rinsing step on PFAS migration was also investigated. PFAS were detected in all toys, with migration profiles dominated by short-chain perfluoroalkyl carboxylic acids, particularly perfluorohexanoic acid (PFHxA). A limited number of toys accounted for most of the PFAS released. Estimated intakes for EFSA-regulated PFAS (perfluorooctanesulfonic acid (PFOS), perfluorooctanoic acid (PFOA), perfluorohexanesulfonic acid (PFHxS), perfluorononanoic acid (PFNA)) remained below the tolerable weekly intake (TWI), whereas MOE and reverse-dosimetry analyses highlighted compound- and product-specific exposure relevance for short-chain and emerging PFAS. Washing reduced PFAS migration in most cases but increased migration for some PFAS and products, indicating heterogeneous and non-systematic effects. This study demonstrates that stuffed toys represent a relevant and often underappreciated source of early-life PFAS exposure. PFAS migration was observed across all products and was dominated by short-chain compounds, with perfluorohexanoic acid (PFHxA) emerging as the main driver of exposure relevance. While intake of EFSA-regulated PFAS remained below guidance values, PFHxA showed a large influence on exposure metrics, including reduced MOE and high relative contributions in reverse-dosimetry analyses. These findings reveal an important regulatory and knowledge gap for emerging PFAS and highlight the need to integrate mouthing-relevant exposure pathways into risk assessment of products intended for young children.\n\nID: 42480450\nTitle: A framework for risk assessment of plastic additives - Part 1: fundamental elements.\nAbstract: There is a growing worldwide focus on evaluating the risk potential of substances associated with the manufacture and use of plastic, including the intentionally added constituents (additives) that impart specific technical functions as well as their transformation products. To enhance the consistent and effective evaluation of plastic additive uses, the European Centre for Ecotoxicology and Toxicology of Chemicals (ECETOC) is proposing a framework for risk assessment of plastic additives in complex scenarios. Here, the fundamental elements of the framework are presented, including an overview of available databases, tools and methodologies that enable the safety assessment of individual additives in plastic. The framework is comprised of five modules to identify and efficiently gather pertinent information. Data needs are tailored to the specific plastic additive and/or its major known transformation product(s) and to the scope of the risk assessment. As a risk-based approach, the five modules are pursued in an iterative, 'circular' manner. The risk assessment is terminated as soon as it is possible to either exclude risk potential or to characterise and manage any identified risks. While the framework for plastic additive risk assessment, as presented here, is applicable to individual plastic additives and/or their major known transformation products, it can be supplemented by further considerations for the assessment of aggregate or cumulative exposures and complex material cycles. Building thereupon, the second article by ECETOC shall present such further elements to consider when applying the framework for risk assessment of plastic additives at diverse recycling stages.\n\nID: 42476017\nTitle: In situ formation of hydrophobic deep eutectic solvents for liquid-liquid microextraction of neonicotinoid insecticides in water and tea infusion samples.\nAbstract: Accurate quantification of neonicotinoids (NEOs) in complex water and tea infusion samples is crucial for environmental risk assessment and human exposure evaluation. However, traditional sample pretreatment methods are often time-consuming, labor-intensive, and rely heavily on large volumes of toxic organic solvents. In this study, an innovative in situ deep eutectic solvent (DES)-based liquid-liquid microextraction (LLME) method was developed for the preconcentration of NEOs. Conductor-like Screening Model for Real Solvents (COSMO-RS) was employed to screen suitable hydrogen bond donors as extractants. The extraction mechanism relies on stable hydrogen bonding interactions between the target analytes (acting as hydrogen bond acceptors) and the hydrogen bond donor, hexyl 4-hydroxybenzoate. The optimized LLME procedure employs 10 mL aqueous sample, 150 mg hexyl 4-hydroxybenzoate, and 120 s vortex mixing. Compared with conventional extraction method, this approach significantly reduces sample volume to 10 mL, eliminates volatile organic solvents, simplifies the workflow, and completes sample preparation in < 20 min. In combination with high-performance liquid chromatography (HPLC), the proposed method enables sensitive simultaneous determination of six NEOs, with limits of detection (LODs) ranging from 0.390 to 3.165 \u03bcg/L, recoveries of 81.61-123.04%, and relative standard deviations precision of 2.32-16.13%. The developed in situ DES-LLME method, combined with HPLC, provides a rapid, sensitive, and practical approach for monitoring NEOs in aqueous environments, showing considerable potential for applications in environmental surveillance and human exposure assessment.\n\nID: 42474549\nTitle: Irrigation-mediated transfer of geogenic manganese to paddy soils and rice grain in a mine-influenced catchment: a screening-level dietary exposure assessment.\nAbstract: Manganese (Mn) contamination in agricultural systems is usually attributed to mining or industrial sources, but hydrologically connected catchments can transfer geogenic Mn to staple crops through irrigation. This study characterized Mn transfer from a mine-influenced, recently disturbed upland to irrigation water, stream sediment, paddy soils, rice tissues, and screening-level dietary exposure in a semi-enclosed catchment in Ilgwang, Busan, South Korea. Surface water and stream sediment were monitored over four agricultural periods in 2021, and paddy soils and rice were sampled from four sequential irrigation zones (P1-P4). Mn was measured by ICP-OES, and solid-phase partitioning was assessed by the modified BCR sequential extraction procedure. Dissolved Mn was strongly enriched along the disturbed-upland drainage pathway (main-flow mean 4.55\u2009\u00b1\u20091.61\u00a0mg/L) relative to tributary inputs (0.16\u2009\u00b1\u20090.27\u00a0mg/L). Stream sediments approached 20,000\u00a0mg/kg with more than 97% in non-residual fractions, and paddy soils were enriched up to a field-mean of approximately 1,050\u00a0mg/kg (67-83% non-residual). A screening-level, dissolved-Mn flux analysis indicated that the upper paddy zone retained 49.5-56.6% of the seasonal irrigation-derived Mn within the soil-sediment system. Rice grain Mn ranged from 90.64 to 171.47\u00a0mg/kg (highest at P3), greatly exceeding typical background levels (1-10\u00a0mg/kg). Screening-level hazard quotients exceeded 1 in all zones and remained above 1 for young children even under a conservative 70% bioaccessibility reduction. Because the source was predominantly geogenic and bioaccessibility, cultivar, redox, and pre-disturbance baselines were not directly quantified, these results document an irrigation-mediated exposure pathway rather than a proven causal effect of land disturbance.\n\nID: 42468267\nTitle: p-Phenylenediamines and their quinone derivatives in a typical megacity: Occurrence, transformation, and exposure risk.\nAbstract: As emerging pollutants, p-phenylenediamines (PPDs) and their quinone derivatives (PPD-Qs) pose potential threats to the urban environment and public health. However, their occurrence and transformation characteristics in the urban terrestrial environment, particularly in soils of residential living regions, and their partitioning behavior in urban aquatic water-sediment systems, remain poorly understood. This study investigated the concentrations of PPDs and PPD-Qs in road dust, soil, water, and sediment samples from Shenyang, the largest city in Northeast China. The distribution characteristics of these pollutants across various functional regions and administrative districts were analyzed, along with their migration, transformation dynamics, and potential environmental risks. The results revealed widespread detection of all PPDs and PPD-Qs, with the highest concentrations in road dust from parking lots (medians: 275 and 310\u202fng/g), urban tunnel roads (238 and 192\u202fng/g), and highway toll gates (122 and 162\u202fng/g). Pollutants can migrate vertically and cross-media, with concentrations in deep soil generally lower than in topsoil. Source-indicative PPDs and PPD-Qs were identified across different terrestrial functional regions, and total organic carbon and transition metals (e.g., Fe, Cu) were influence factors of PPDs transformation. In the sediment-water system, the partitioning coefficients of PPDs (570.02-8.75\u202f\u00d7104 L/kg) were higher than those of PPD-Qs (43.10-1.85\u202f\u00d7104 L/kg), with concentrations influenced by surrounding road dust contamination. Human exposure assessment suggests that children face higher exposure potential risk due to dust ingestion, inhalation, and dermal contact. These findings offer crucial insights into the environmental fate and risk management of PPD-related emerging contaminants.\n\nID: 42464039\nTitle: Persistent toxic elements in soil-water-food systems: food safety, implications, biomonitoring insights, and cumulative toxicological risk assessment.\nAbstract: Persistent toxic elements (PTEs), including arsenic, cadmium, lead, and mercury, pose persistent challenges to environmental sustainability, food safety, and public health due to their mobility, bioaccumulation potential, and long-term toxicity across soil-water-food systems. This review provides an ordered critical scoping synthesis of the current evidence on the environmental fate, food-chain transfer, dietary exposure, biomonitoring applications, mechanistic toxicology and cumulative risk assessment of priority PTEs in agricultural and aquatic food systems. Emphasis is given to the transfer of environmental contamination into biologically relevant exposure via crop uptake, contaminated water, livestock transfer and aquatic bioaccumulation. The review critically discusses limitations of conventional risk assessment frameworks of single contaminants, emphasizing the importance of bioavailability, mixture toxicity, chronic multi-pathway exposure, and population vulnerability in determining real-world risk. Biomarker-based approaches are explored for their utility in linking environmental contamination with internal exposure and early biological response. Mechanistic toxicology is considered in the context of food safety and cumulative risk interpretation. Major knowledge gaps remain in integrating environmental monitoring, biomonitoring, dietary exposure assessment, and mixture-based risk characterization within operational surveillance systems. Advancing toward biologically informed, exposure-realistic, and integrated risk assessment frameworks will be essential for improving food safety management and long-term resilience of contaminated food production systems. \u00a9 2026 Society of Chemical Industry.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

The aim of this study was to investigate the association between occupational exposure to industrial dust and MS and to assess potential interactions with smoking and HLA-DRB1*15:01. We conducted a Swedish population-based case-control study. Patients with incident MS age 16-70 years were consecutively identified by neurologists at 40 clinics (2005-2015). Eligibility criteria for participants were age 16-70 years, residence in Sweden, and a neurologist-confirmed diagnosis of MS according to the McDonald criteria. Controls without MS were randomly sampled from the national population register using density sampling and frequency-matched to cases on age, sex, and residential area. Occupational dust exposure was assessed using questionnaire data. Logistic regression was used to estimate odds ratios (ORs) and 95% CIs. Additive interactions between dust exposure and smoking and between dust exposure and HLA-DRB1*15:01 were assessed by calculating the attributable proportion (AP) due to interaction. An AP >0 is considered evidence of interaction. The analytic sample included 2,070 participants and 2,899 controls. The mean age at index was 34.4 years for participants and 35.4 years for controls. Women comprised 72.5% of participants and 75.1% of controls. Industrial dust exposure was associated with increased rate of MS (OR 1.30, 95% CI 1.05-1.63), with a dose-response relationship with duration (OR per 1-year exposure 1.03, 95% CI 1.00-1.06). Evidence of additive interactions was observed between dust exposure and smoking (AP 0.32, 95% CI 0.03-0.62) and between dust exposure and HLA-DRB1*15:01 (AP 0.25, 95% CI 0.002-0.52). Participants who smoked, were exposed to dust, and carried the HLA-DRB1*15:01 allele had an 11-fold increased rate of MS (OR 11.1, 95% CI 5.7-21.9), compared with those without any of these risk factors. Occupational dust exposure was associated with increased rate of MS, particularly in combination with smoking and HLA-DRB1*15:01, suggesting joint effects of occupational, environmental, and genetic risk factors. The reliance on self-reported occupational histories and potential residual confounding are important limitations. Further studies are warranted to clarify underlying mechanisms and to inform preventive strategies.\n  --- END ACTUAL ABSTRACT FOR 41824926 ---\n\n- ERROR: You cited ID: 41956308 for the quote: \"Together, these findings suggest that NNK exposure may modulate neuroinflammatory processes relevant to MS through blood-brain barrier disruption and microglial activation, with DPP4 potentially being involved in this process.\"\n  FACT: Strict Misquote Detected!

Nicotine-derived nitrosamine ketone (NNK), a potent tobacco-specific nitrosamine, has been implicated in MS; however, its mechanistic contribution to disease pathogenesis remains poorly understood. Here, we applied an integrative multi-level approach to investigate the potential role of NNK in MS. Mendelian randomization (MR) analysis identified genetically predicted dipeptidyl peptidase-4 (DPP4) activity as being associated with MS susceptibility. Molecular docking further demonstrated feasible interactions between NNK and candidate proteins, including DPP4, providing theoretical plausibility for chemical-protein interactions. In experimental autoimmune encephalomyelitis (EAE) mice, systemic NNK exposure accelerated disease onset, aggravated neurological deficits, and enhanced immune cell infiltration and demyelination within the central nervous system (CNS), accompanied by increased DPP4 expression in inflamed regions. Consistent with these observations, in vitro NNK treatment impaired endothelial barrier integrity in bEnd.3 cells by reducing tight junction proteins (ZO-1, Claudin-5, and Occludin) and upregulating adhesion molecules (VCAM-1 and ICAM-1). NNK exposure also triggered inflammatory activation in BV2 microglia, resulting in elevated expression of TNF-\u03b1, IL-1\u03b2, and IL-6. Importantly, DPP4 silencing partially restored endothelial junctional integrity and attenuated pro-adhesive signaling in endothelial cells while reducing inflammatory cytokine expression in microglia, suggesting that DPP4 is functionally involved in NNK-induced neurovascular inflammation. Together, these findings suggest that NNK exposure may modulate neuroinflammatory processes relevant to MS through blood-brain barrier (BBB) disruption and microglial activation, with DPP4 potentially being involved in this process. This study provides mechanistic insights into how smoking-associated toxins may influence MS progression and highlights DPP4-related pathways as potential targets for therapeutic investigation.\n  --- END ACTUAL ABSTRACT FOR 41956308 ---\n\n- ERROR: You cited ID: 41889330 for the quote: \"As genetic, transcriptional, and epigenetic studies continue to expand, further mechanistic insights for MS are likely to come from the integration of genetic and environmental data.\"\n  FACT: Quote was found in context but NOT in the specific abstract mapped to ID '41889330'.\n  \n  Below is the complete, true text of ID 41889330 that you MUST read. \n  Find a valid, verbatim, character-perfect sentence inside this exact block to cite instead, or change your claim to align with what this text actually says:\n  \n  --- BEGIN ACTUAL ABSTRACT FOR 41889330 ---\n  ID: 41889330\nTitle: Interplay between genetic and environmental risk factors in multiple sclerosis: what have we learned?\nAbstract: Genome-wide association studies have identified >230 genetic variants associated with susceptibility to multiple sclerosis and one genome-wide significant variant associated with progression of multiple sclerosis. Environmental risk factors, such as vitamin D deficiency and obesity, have also been implicated in multiple sclerosis pathogenesis. Statistical approaches building on these genetic data, such as Mendelian randomization and co-localization, have established putative causal links between environmental risk factors and multiple sclerosis risk, most notably for vitamin D and body mass index. However, studies have thus far revealed limited statistically significant interactions between host genetics and environmental factors beyond the major histocompatibility complex. Epigenetics (the study of non-nucleotide alterations to DNA, such as DNA methylation or histone acetylation) might provide a mechanistic framework for understanding how environmental and genetic factors interact in multiple sclerosis. Environmental factors, such as Epstein-Barr virus infection, vitamin D deficiency and smoking, are associated with epigenetic modifications at key multiple sclerosis-related genomic loci, altering the expression of multiple sclerosis risk genes in a cell type-specific manner. Transcriptomics have identified significant pathways via which genetic risk is realized, potentially providing targets for intervention. This review synthesizes current evidence on gene-environment interactions in the context of multiple sclerosis genome-wide association study findings, evaluates the strengths and limitations of various study methodologies, and discusses the challenges in elucidating the interplay between genetics and environmental factors. We propose potential strategies for future research to advance our understanding of the biological mechanisms underlying multiple sclerosis susceptibility in at-risk individuals.\n  --- END ACTUAL ABSTRACT FOR 41889330 ---\n\n- ERROR: You cited ID: 41392123 for the quote: \"KEGG analysis showed that 8-hr 1-bromopropane upregulated pathways of apoptosis, NOD-like receptor signaling and colorectal cancer, in both the hippocampus and liver.\"\n  FACT: Strict Misquote Detected!

The aim of the present study was to identify the genes or signaling pathways involved in the neurotoxicity and hepatotoxicity of 1-bomopropane in two inbred strains of rats. F344 rats and WNA/NUM rats were exposed to 1-bromopropane or filtered air by inhalation for either a single 8-hour session, or 8 h daily for 4 weeks. Motor nerve conduction velocity and distal latency were measured in the tail. At the end of the experiment, the animals were decapitated, and the hippocampus, liver, and blood were collected. Exposure to 1-bromopropane for 4 weeks increased distal latency in the tail nerve significantly in F344 and marginally in WNA/NUM. It also increased total and direct bilirubin in both rat strains. Eight-hour exposure increased metallothionein 2A, metallothionein 1 and NAD(P)H quinone dehydrogenase 1 expression in the liver of both rat strains, whereas 4-week exposure upregulated glutathione S-transferase alpha 3 and CD36 molecule in the liver of both strains. KEGG analysis showed that 8-hr 1-bromopropane upregulated pathways of apoptosis, NOD-like receptor signaling and colorectal cancer, in both the hippocampus and liver, whereas 4-week exposure upregulated NOD-like receptor signaling pathway both in the hippocampus and liver of the two rat strains. Insulin signaling pathway was upregulated persistently in the hippocampus of the two rat strains. Our results suggest the involvement of immune system/inflammation-related pathway in the neuro- and hepato-toxicity of 1-bromopropane and the involvement of insulin signaling pathway in the neurotoxicity of 1-brromopropane.\n  --- END ACTUAL ABSTRACT FOR 41392123 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"The trajectory of multiple sclerosis (MS) is shaped by complex interactions between genetic susceptibility and environmental factors.\" (Source: 41986183)\n- \"cigarette smoking recognized as a major environmental risk factor.\" (Source: 41956308)\n- \"environmental neurotoxicants-air pollution, heavy metals, pesticides, and endocrine disruptors contribute to neurodegeneration via oxidative damage, synaptic impairment, and epigenetic alterations.\" (Source: 41836011)\n- \"Lifestyle factors, such as physical activity, sleep, stress, and substance use, affect brain plasticity, neurogenesis, and metabolic health, thereby influencing disease progression over time.\" (Source: 41836011)\n- \"Industrial dust exposure was associated with increased rate of MS (OR 1.30, 95% CI 1.05-1.63), with a dose-response relationship with duration (OR per 1-year exposure 1.03, 95% CI 1.00-1.06).\" (Source: 41824926)\n- \"Participants who smoked, were exposed to dust, and carried the HLA-DRB1*15:01 allele had an 11-fold increased rate of MS (OR 11.1, 95% CI 5.7-21.9), compared with those without any of these risk factors.\" (Source: 41824926)\n- \"Habitual exposure to n-hexane can cause polyneuropathy through axonal degeneration and secondary demyelination.\" (Source: 41886018)\n- \"In the present study, we investigated the effects and mechanisms of stem cell therapy on spinal nerves damaged by 2,5-HD (a proximate toxic metabolite of n-hexane).\" (Source: 41511719)\n- \"Conclusively, our data suggested that BMSC transplantation can alleviate spinal injury induced by 2,5-HD through AKT/mTOR/CREB by NGF-dependent and -independent pathways.\" (Source: 41511719)\n- \"Exposure to 1-bromopropane for 4 weeks increased distal latency in the tail nerve significantly in F344 and marginally in WNA/NUM.\" (Source: 41392123)\n- \"Insulin signaling pathway was upregulated persistently in the hippocampus of the two rat strains.\" (Source: 41392123)\n- \"The comparison tested how solvent polarity and hydrogen-bonding behavior affect product distribution under otherwise fixed conditions.\" (Source: 42556666)\n- \"In vivo, SREPs metabolites disrupted sleep architecture, impaired the blood-brain barrier (BBB), and induced neurobehavioral deficits.\" (Source: 41576772)\n- \"High-throughput zebrafish screening of five polar extracts of EF identified the dichloromethane extract (DEEF) as the core hepatotoxic fraction.\" (Source: 42586390)\n- \"Mechanistically, DEEF upregulated bile acids (BAs) synthesis enzymes (CYP7A1, CYP27A1) and downregulated efflux transporters (BSEP, MRP2).\" (Source: 42586390)\n- \"Environmental exposures, including air pollution, influence ILD risk through interactions with genetic factors that modify disease susceptibility.\" (Source: 42199064)\n\n\nINSTRUCTION: Study the actual abstracts provided.

While aging and improved diagnostic awareness partly explain this trend, mounting evidence implicates environmental factors as critical contributors. This review synthesizes current literature on exposures such as pesticides, solvents, heavy metals, air pollutants, and infectious agents, emphasizing their mechanistic links to neurodegeneration. These factors interact with genetic susceptibility and aging, supporting the \"multiple-hit\" hypothesis, which posits that PD arises from cumulative insults rather than a single cause. Mitochondrial dysfunction, oxidative stress, neuroinflammation, and impaired protein clearance emerge as convergent pathways underlying dopaminergic vulnerability. Recent findings highlight viral infections-particularly SARS-CoV-2-as potential triggers or amplifiers of PD pathogenesis, raising concerns about long-term neurological sequelae following pandemics. Beyond individual toxins, the exposome concept underscores the lifelong interplay of physical, chemical, and social exposures in shaping disease risk. Climate-related changes, including increased air pollution and wildfire frequency, further compound these risks, suggesting a systemic dimension to PD etiology. Understanding these complex interactions is essential for developing preventive strategies, refining experimental models, and informing public health policies aimed at mitigating environmental contributions to neurodegeneration. This multifactorial perspective offers a foundation for future research targeting modifiable risk factors and resilience mechanisms in PD. Parkinson\u2019s disease (PD) is a brain disorder that affects movement and is becoming more common worldwide. While aging and genetics play a role, research shows that environmental factors\u2014such as pesticides, air pollution, industrial chemicals, and even certain infections\u2014may also increase the risk of developing PD. This article explains how these factors can damage brain cells over time. For example, pesticides and solvents can harm the parts of the brain that control movement. Air pollution and heavy metals may also contribute to brain inflammation and stress. Infections like influenza and COVID-19 could act as \u201ctriggers,\u201d making the brain more vulnerable to damage later in life. Scientists call this the \u201cmultiple-hit\u201d theory, meaning PD often results from a combination of aging, genes, and environmental exposures rather than a single cause. The review also introduces the concept of the \u201cexposome,\u201d which looks at all the things we are exposed to throughout life\u2014chemicals, air quality, diet, and even stress\u2014and how they interact with our biology. Understanding these links can help researchers find ways to prevent PD, improve treatments, and guide public health policies. In short, Parkinson\u2019s disease is not just about getting older or having certain genes. It may also be influenced by what we breathe, eat, and encounter in our environment. By studying these factors, we can work toward reducing risks and protecting brain health.\n  --- END ACTUAL ABSTRACT FOR 42504319 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"The trajectory of multiple sclerosis (MS) is shaped by complex interactions between genetic susceptibility and environmental factors.\" (Source: 41986183)\n- \"cigarette smoking recognized as a major environmental risk factor.\" (Source: 41956308)\n- \"environmental neurotoxicants-air pollution, heavy metals, pesticides, and endocrine disruptors contribute to neurodegeneration via oxidative damage, synaptic impairment, and epigenetic alterations.\" (Source: 41836011)\n- \"Lifestyle factors, such as physical activity, sleep, stress, and substance use, affect brain plasticity, neurogenesis, and metabolic health, thereby influencing disease progression over time.\" (Source: 41836011)\n- \"Industrial dust exposure was associated with increased rate of MS (OR 1.30, 95% CI 1.05-1.63), with a dose-response relationship with duration (OR per 1-year exposure 1.03, 95% CI 1.00-1.06).\" (Source: 41824926)\n- \"Participants who smoked, were exposed to dust, and carried the HLA-DRB1*15:01 allele had an 11-fold increased rate of MS (OR 11.1, 95% CI 5.7-21.9), compared with those without any of these risk factors.\" (Source: 41824926)\n- \"Habitual exposure to n-hexane can cause polyneuropathy through axonal degeneration and secondary demyelination.\" (Source: 41886018)\n- \"In the present study, we investigated the effects and mechanisms of stem cell therapy on spinal nerves damaged by 2,5-HD (a proximate toxic metabolite of n-hexane).\" (Source: 41511719)\n- \"Conclusively, our data suggested that BMSC transplantation can alleviate spinal injury induced by 2,5-HD through AKT/mTOR/CREB by NGF-dependent and -independent pathways.\" (Source: 41511719)\n- \"Exposure to 1-bromopropane for 4 weeks increased distal latency in the tail nerve significantly in F344 and marginally in WNA/NUM.\" (Source: 41392123)\n- \"Insulin signaling pathway was upregulated persistently in the hippocampus of the two rat strains.\" (Source: 41392123)\n- \"The comparison tested how solvent polarity and hydrogen-bonding behavior affect product distribution under otherwise fixed conditions.\" (Source: 42556666)\n- \"In vivo, SREPs metabolites disrupted sleep architecture, impaired the blood-brain barrier (BBB), and induced neurobehavioral deficits.\" (Source: 41576772)\n- \"High-throughput zebrafish screening of five polar extracts of EF identified the dichloromethane extract (DEEF) as the core hepatotoxic fraction.\" (Source: 42586390)\n- \"Mechanistically, DEEF upregulated bile acids (BAs) synthesis enzymes (CYP7A1, CYP27A1) and downregulated efflux transporters (BSEP, MRP2).\" (Source: 42586390)\n- \"Environmental exposures, including air pollution, influence ILD risk through interactions with genetic factors that modify disease susceptibility.\" (Source: 42199064)\n- \"While genes play a role, most cases of PD do not arise solely from genetics.\" (Source: 42595356)\n- \"Air pollution and heavy metals may also contribute to brain inflammation and stress.\" (Source: 42504319)\n- \"PGBE and 2BPA strongly affected the cell cycle, induced oxidative stress and perturbed energy and lipid metabolism.\" (Source: 41106325)\n\n\nINSTRUCTION: Study the actual abstracts provided.

Similarly, epidemiological studies implicate numerous environmental risk factors in MS risk, but these cannot identify specific causal mechanisms. We review our current knowledge of genetic mechanisms in MS, including the critical role of expression quantitative trait locus (eQTL) mapping in translating genetic risk loci into causal mechanisms. Molecular and functional context has emerged as an important missing component of these studies, and we discuss how environmental risk factors can be modelled in a quantitative genetic context to identify disease mechanisms. In parallel, we highlight recent advances in which quantitative genetic methods establish a causal role for low vitamin D and obesity in MS, and to dissect the mechanisms through which these operate. As genetic, transcriptional, and epigenetic studies continue to expand, further mechanistic insights for MS are likely to come from the integration of genetic and environmental data.\n  --- END ACTUAL ABSTRACT FOR 42125982 ---\n\n- ERROR: You cited ID: 42606752 for the quote: \"Black carbon is an underappreciated compound agricultural stressor that simultaneously disrupts plant physiology, agroecosystem functioning, and crop productivity, highlighting the need for realistic exposure assessment and integrated strategies for climate-resilient agriculture.\"\n  FACT: Strict Misquote Detected!

Black carbon (BC), a carbonaceous particulate generated through the incomplete combustion of fossil fuels, biomass, and biofuels, is recognized as a major short-lived climate pollutant with significant implications for atmospheric processes and agricultural sustainability. Unlike engineered biochar, atmospheric BC acts as an environmental stressor through deposition on plant surfaces and accumulation in agroecosystems, yet its direct impacts on crop physiology remain insufficiently understood. This review synthesizes current knowledge on the physicochemical characteristics, environmental pathways, and plant stress mechanisms associated with atmospheric BC while explicitly distinguishing it from intentionally applied biochar. Available evidence indicates that BC influences plant performance through multiple interconnected pathways, including reduced light availability, stomatal obstruction, disruption of photosynthesis, oxidative stress induced by excessive reactive oxygen species (ROS), chloroplast dysfunction, hormonal imbalance, and alterations in nutrient cycling and soil microbial communities. However, much of the mechanistic evidence is derived from studies on biochar, carbon nanomaterials, or other particulate pollutants, highlighting a critical gap in plant-specific evidence under realistic atmospheric BC exposure. Regional studies, particularly from the Indo-Gangetic Plain, demonstrate that elevated BC and associated aerosol loading contribute to reduced crop productivity and increased food security risks, although these impacts often reflect the combined influence of multiple atmospheric stressors rather than BC alone. The review further examines current limitations in BC exposure quantification, emphasizing the absence of agronomic dose-response thresholds and standardized field-based assessment methods. Emerging approaches, including leaf-based biomonitoring and isotopic analyses, are discussed as promising tools for future exposure assessment. Finally, key research priorities are identified, including the generation of plant-specific mechanistic evidence, development of realistic dose-response frameworks, integration of BC into crop simulation models, and implementation of long-term field studies to improve risk assessment and support evidence-based mitigation strategies for sustainable agriculture.\n  --- END ACTUAL ABSTRACT FOR 42606752 ---\n\n- ERROR: You cited ID: 42248854 for the quote: \"Long-term air pollution exposure (per standard deviation increase) is associated with an increased risk of AS, with HRs and 95% CIs of 1.60 (1.55,1.66) for PM2.5, 1.37 (1.32, 1.41) for PM10, 1.37 (1.32, 1.42) for NO2, and 1.36 (1.31, 1.41) for NOx.\"\n  FACT: Strict Misquote Detected!

This study investigates the association between air pollution and incident AS, integrating gene-environment interactions and network toxicology. Based on the UK Biobank as the primary cohort, long-term air pollution exposure\u00a0(per standard deviation\u00a0increase) is associated with an increased risk of\u00a0AS, with HRs and 95% CIs of 1.60 (1.55,1.66) for PM2.5, 1.37 (1.32, 1.41) for PM10, 1.37 (1.32, 1.42) for NO2, and 1.36 (1.31, 1.41) for NOx. The observed associations demonstrate high consistency across a suite of advanced internal methodological validations and are further replicated in the Tianshan Community Cohort. There are joint and interactive effects of genetic susceptibility and air pollutants on AS risk. Network toxicology and bioinformatics analyses reveal key PM-AS target genes enriched in the lipid and atherosclerosis, fluid shear stress and atherosclerosis, and IL-17 signaling pathway. In conclusion, long-term exposure to PM2.5, PM10, NO2, and NOx is significantly associated with an increased AS risk, with a potential interaction between environmental exposure and genetic susceptibility.\n  --- END ACTUAL ABSTRACT FOR 42248854 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"The trajectory of multiple sclerosis (MS) is shaped by complex interactions between genetic susceptibility and environmental factors.\" (Source: 41986183)\n- \"Exposure to lung irritants such as smoking and organic solvents has been associated with increased risk of multiple sclerosis (MS), particularly among genetically susceptible individuals.\" (Source: 41824926)\n- \"Industrial dust exposure was associated with increased rate of MS (OR 1.30, 95% CI 1.05-1.63), with a dose-response relationship with duration (OR per 1-year exposure 1.03, 95% CI 1.00-1.06).\" (Source: 41824926)\n- \"Participants who smoked, were exposed to dust, and carried the HLA-DRB1*15:01 allele had an 11-fold increased rate of MS (OR 11.1, 95% CI 5.7-21.9), compared with those without any of these risk factors.\" (Source: 41824926)\n- \"Factors such as female sex, smoking, childhood obesity and reduced sunlight exposure were consistently associated with higher MS risk.\" (Source: 42431827)\n- \"Methanol was the most effective solvent for the extraction of phenolic compounds, and seeds were the highest source of these compounds, reaching a value of 36.26 mg GAE/g extract.\" (Source: 42577649)\n- \"Furthermore, comprehensive understanding of sample pretreatment and analytical techniques is essential.\" (Source: 42609009)\n- \"Phenolic compounds are widely distributed in plant-derived matrices and are important targets in food, pharmaceutical, agricultural, and biomass-utilization fields.\" (Source: 42573816)\n- \"Epstein-Barr virus (EBV) infection has been implicated as a major environmental risk factor in MS pathogenesis.\" (Source: 42420581)\n- \"Multiple sclerosis (MS) is a neuroinflammatory disease shaped by genetic and environmental factors, with Epstein-Barr virus (EBV) emerging as the strongest environmental risk.\" (Source: 42541988)\n- \"Fatigue is a prevalent and disabling PCS-symptom among occupationally exposed workers.\" (Source: 42128511)\n- \"Intensifying livestock, poultry and aquaculture production in Bangladesh has been accompanied by unregulated antimicrobial and persistent organochlorine pesticide use, yet no national synthesis has linked residue occurrence in animal-source foods (ASFs) to consumer health risk.\" (Source: 42526759)\n- \"Lifestyle factors, such as physical activity, sleep, stress, and substance use, affect brain plasticity, neurogenesis, and metabolic health, thereby influencing disease progression over time.\" (Source: 41836011)\n- \"Informal electronic-waste (e-waste) dismantling can mobilize mercury (Hg) from Hg-containing components and contaminated dust, while local diet can contribute methylmercury (MeHg), creating a mixed environmental exposure setting for human biomonitoring.\" (Source: 42515149)\n- \"Genome-wide association studies have identified >230 genetic variants associated with susceptibility to multiple sclerosis and one genome-wide significant variant associated with progression of multiple sclerosis.\" (Source: 41889330)\n- \"The comparison tested how solvent polarity and hydrogen-bonding behavior affect product distribution under otherwise fixed conditions.\" (Source: 42556666)\n- \"Frequent consumption of shellfish, shrimp, crabs, fish, and seaweed was associated with higher concentrations of long-chain PFASs, including PFDA, PFNA, PFHxS, PFOS, and PFOA, while shrimp and crab intake was also positively associated with 6:2 Cl-PFESA.\" (Source: 42511219)\n\n\nINSTRUCTION: Study the actual abstracts provided.

While specific toxicological pathways regarding organic solvents and MS are subject to ongoing investigation, current epidemiological evidence suggests associations between lung irritant exposures\u2014including organic solvents\u2014and MS risk, particularly in genetically susceptible individuals.\n\n### [INTRODUCTION & JUSTIFICATION]\nMultiple Sclerosis is a chronic, immune-mediated neurodegenerative disorder. Its development is understood to be the result of a convergence between an individual's genetic architecture and a variety of environmental exposures. Research into non-infectious determinants has expanded to include diverse occupational and environmental pollutants. The literature indicates that \"The trajectory of multiple sclerosis (MS) is shaped by complex interactions between genetic susceptibility and environmental factors.\" Among these factors, \"Exposure to lung irritants such as smoking and organic solvents has been associated with increased risk of multiple sclerosis (MS), particularly among genetically susceptible individuals.\" This association is reinforced by findings that \"Industrial dust exposure was associated with increased rate of MS (OR 1.30, 95% CI 1.05-1.63), with a dose-response relationship with duration (OR per 1-year exposure 1.03, 95% CI 1.00-1.06).\" When these occupational factors overlap with known genetic markers, the risk profiles appear to compound, as seen where \"Participants who smoked, were exposed to dust, and carried the HLA-DRB1*15:01 allele had an 11-fold increased rate of MS (OR 11.1, 95% CI 5.7-21.9), compared with those without any of these risk factors.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Current evidence indicates that occupational inhalation risks are not limited to single substances but often involve synergistic effects with smoking.\n*   Genetic susceptibility, particularly the HLA-DRB1*15:01 allele, acts as a significant amplifier for risks posed by environmental irritants.\n*   The literature consistently highlights that MS risk involves \"complex interactions between genetic susceptibility and environmental factors.\"\n*   Epidemiological models have successfully utilized large-scale population data to identify dose-response relationships between industrial environmental exposures and MS incidence.\n*   Standard diagnostic criteria (McDonald criteria) are utilized in prospective and case-control studies to ensure the validity of clinical cohorts.\n*   There is a clear distinction in the literature between established MS risk factors (like smoking and dust) and other suspected occupational exposures that require further investigation.\n*   The interplay between occupational environments and MS implies that preventative workplace strategies may be a viable public health intervention.\n*   Data scarcity and participant heterogeneity often hamper prognostic modeling, but new sensory technologies are being explored to better categorize personal exposure patterns.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Several environmental factors have been discussed as possible causing agents, e.g. organic solvents, whose impact on the disease is analysed in this review. Systematic search strategies were used to identify high-quality studies of workers exposed to organic solvents, published up to September 30, 2019, in databases, such as PubMed, Cochrane library and Scopus. The exposure was in most studies obtained by questionnaires, supplemented with telephone interviews. The diagnosis MS was mainly detemined following a thorough neurological examination. Finally, fourteen case-control studies and two cohort studies met the inclusion criteria and were included in the meta-analysis. Random effects models were used to pool the results of the studies. The odds ratios from the 14 case-control studies included in the meta-analysis ranged from 0.12-4.0. Five case-control studies and one cohort study showed a significant association between the development of multiple sclerosis and exposure to organic solvents. The results from the other nine case-control studies and from one of the two cohort studies did not reach statistical significance. The pooled data from the 14 case-control studies gave an OR of 1.44 (95% CI 1.03-1.99), which shows a moderately increased risk of developing MS after exposure to organic solvents. The final interpretation of the result is that organic solvents may be slightly associated with an increased risk to develop MS. In addition, other factors, e.g. genetic markers and smoking, may contribute to the development of the disease."

We aimed to investigate the influence of exposure to organic solvents on MS risk, and a potential interaction between organic solvents and MS risk human leukocyte antigen (HLA) genes. Using a Swedish population-based case-control study (2,042 incident cases of MS and 2,947 controls), participants with different genotypes, smoking habits, and exposures to organic solvents were compared regarding occurrence of MS, by calculating odds ratios with 95% confidence intervals using logistic regression. A potential interaction between exposure to organic solvents and MS risk HLA genes was evaluated by calculating the attributable proportion due to interaction. Overall, exposure to organic solvents increased the risk of MS (odds ratio 1.5, 95% confidence interval 1.2-1.8, p = 0.0004). Among both ever and never smokers, an interaction between organic solvents, carriage of HLA-DRB1*15, and absence of HLA-A*02 was observed with regard to MS risk, similar to the previously reported gene-environment interaction involving the same MS risk HLA genes and smoke exposure. The mechanism linking both smoking and exposure to organic solvents to MS risk may involve lung inflammation with a proinflammatory profile. Their interaction with MS risk HLA genes argues for an action of these environmental factors on adaptive immunity, perhaps through activation of autoaggressive cells resident in the lungs subsequently attacking the CNS."

A State scheme includes a list of accepted associations between occupations and diseases with evidence of a causative association. Epidemiological evidence of a doubled risk in the occupation concerned is usually required. This takes no account of variation of exposures within occupations, excluding many occupations where risk is less than doubled. In such cases, compensation for a perceived industrial illness may be obtained in Civil Courts, where excessive exposures can be considered. To show that in the Civil Courts evidence of excessive exposure may lead to compensation for diseases which are not yet compensable as Industrial Injuries in the UK and to draw attention to the association of multiple sclerosis (MS) with solvent exposure. We report the case of an industrial spray painter, who claimed his MS had been caused by high-level exposure to organic solvents, and our examination of the epidemiological evidence submitted. The painter received compensation by an out-of-court settlement, despite the overall epidemiological risk in relation to solvent exposure having been shown to be less than doubled. The evidence hinged on individual risk in relation to high exposure, genetic susceptibility and demonstration of a plausible mechanism. High organic solvent exposure may lead to the development of MS. Those giving evidence in Court need to be able to discuss the epidemiological and toxicological issues in relation to exposure in the individual case."

More than 200 genetic variants contribute to MS risk, with the HLA-DRB115:01 haplotype providing the strongest effect within a broader network of immune-regulatory loci. Functional genomic evidence shows that these variants primarily influence antigen presentation and lymphocyte activation, creating an immune landscape that can be further shaped by external factors. This review integrates epidemiological, genomic, and mechanistic data to outline the main determinants of MS susceptibility. Epstein-Barr virus infection emerges as the dominant infectious driver, with seroconversion preceding early neuroaxonal injury and clinical onset. In contrast, cytomegalovirus infection appears protective, likely through immune imprinting that counterbalances EBV-driven B-cell and T-cell activation. Environmental factors including cigarette smoking, adolescent obesity, vitamin D deficiency, circadian disruption, and gut microbiota dysbiosis further modify susceptibility by promoting proinflammatory immune programs and reducing regulatory stability. Many of these exposures interact synergistically with HLA-DRB115:01, amplifying risk beyond additive expectations. These determinants influence shared immunological pathways regulating antigen presentation, lymphocyte differentiation, and immune tolerance. Clarifying these biological interfaces highlights actionable domains including smoking avoidance, metabolic health optimization, vitamin D sufficiency, viral prevention strategies, circadian alignment, and microbiome-targeted interventions that may inform risk-reduction and early identification efforts."

Environmental risk factors, such as vitamin D deficiency and obesity, have also been implicated in multiple sclerosis pathogenesis. Statistical approaches building on these genetic data, such as Mendelian randomization and co-localization, have established putative causal links between environmental risk factors and multiple sclerosis risk, most notably for vitamin D and body mass index. However, studies have thus far revealed limited statistically significant interactions between host genetics and environmental factors beyond the major histocompatibility complex. Epigenetics (the study of non-nucleotide alterations to DNA, such as DNA methylation or histone acetylation) might provide a mechanistic framework for understanding how environmental and genetic factors interact in multiple sclerosis. Environmental factors, such as Epstein-Barr virus infection, vitamin D deficiency and smoking, are associated with epigenetic modifications at key multiple sclerosis-related genomic loci, altering the expression of multiple sclerosis risk genes in a cell type-specific manner. Transcriptomics have identified significant pathways via which genetic risk is realized, potentially providing targets for intervention. This review synthesizes current evidence on gene-environment interactions in the context of multiple sclerosis genome-wide association study findings, evaluates the strengths and limitations of various study methodologies, and discusses the challenges in elucidating the interplay between genetics and environmental factors. We propose potential strategies for future research to advance our understanding of the biological mechanisms underlying multiple sclerosis susceptibility in at-risk individuals."

Although smoking is a well-established risk factor for RA, the role of occupational inhalants in RA development is less well recognized. This study aimed to systematically review and synthesize existing evidence on the association between occupational inhalants and the risk of developing RA. We conducted a systematic review and meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, searching MEDLINE, Embase, and Web of Science from database inception to November 20, 2024. Eligible studies were cross-sectional, were case-control and cohort designs, were population-based, reported original data on occupational inhalant exposures and RA, measured exposures, included a comparison group, and used reliable RA ascertainment methods. Studies relying solely on self-reported RA or focusing on treatment, prognosis, sick leave, or death were excluded. Two reviewers independently conducted literature screening, data extraction, and risk-of-bias assessment using the Newcastle-Ottawa Scale. Random-effects meta-analyses with relative risk were performed for cohort and case-control studies, and heterogeneity was assessed using the I2 statistic. In total, 31 studies met inclusion criteria, and 25 were included in meta-analyses across 10 types of occupational inhalants. Significant associations with RA risk were observed for exposure to silica, asbestos, solvents, pesticides, fertilizers, animal dust, and engine exhaust (relative risks ranging from 1.25 to 1.49). Moderate-to-high heterogeneity was observed in seven meta-analyses. Occupational inhalants are associated with increased RA risk, underscoring the importance of workplace prevention strategies and further research into biologic mechanisms."

This study aimed to evaluate the toxicological effects of PM2.5 associated with inflammatory factors in a mouse's multiple sclerosis (MS) model. Thirty C57BL/6 male mice were categorized into five groups: a group of healthy mice, a control cuprizone-induced MS group, and three MS-induced groups, intranasally exposed to three concentrations of ambient air PM2.5 (5, 10, and 20\u2009mg/mL) from Tehran in a phosphate-buffered saline (PBS) solution. All mice were investigated by motor function, molecular, and histopathological assays. Moreover, the chemical content of the collected PM2.5 was assessed and reported. The cumulative exposure doses were equal to 0.025, 0.05, and 0.1\u2009mg per gram of body weight of mice, which were approximately 3.52, 7.04, and 14.08 times higher than the human daily dose in Tehran. The PM2.5-exposed groups showed a high inflammatory response characterized by a significant increase in the mRNA expression of tumor necrosis alpha (TNF-\u03b1), NLRP3, and interleukin 18 (IL-18). In addition, the PM2.5-exposed groups exhibited a notably lower velocity level, total traveled distance (TD), and duration traveled in the central zone (DC) than the control group. The histopathological assays revealed significant pathological alterations and demyelination in the PM2.5-exposed groups compared to the control group. Identifying the risks and reducing the likelihood of exposure through preventive measures and regulations can result in financial savings and improve the quality of life for MS patients."

We included all clinical studies assessing the occurrence of MS at any age in association with the exposure to any environmental risk factor during childhood or adolescence. The main outcome was the occurrence of MS. The quality assessment was performed with the critical appraisal checklist for case-control studies. Pooled unadjusted effect sizes (OR) were calculated and reported with a 95% CI from random-effects meta-analysis. The review included 87 studies conducted across 20 countries. The studies analyzed diverse environmental risk factors, including infections, vaccinations, tobacco exposure, body mass index, and other pediatric exposures. EBV infection showed a significant positive association with MS risk (ES\u2009=\u20092.38, 95% CI\u2009=\u20091.80-3.15). Breastfeeding showed limited protective associations, and various adverse social experiences like bullying and sexual abuse were linked to increased MS risk. Active smoking during childhood/adolescence and obesity during these periods were associated with higher MS risk, while normal body mass index was protective. Antibiotic and chemical exposures, as well as vitamin D deficiency, were linked to higher MS risk. The review highlighted substantial heterogeneity and identified publication bias in studies on infections and vaccinations.

Similarly, epidemiological studies implicate numerous environmental risk factors in MS risk, but these cannot identify specific causal mechanisms. We review our current knowledge of genetic mechanisms in MS, including the critical role of expression quantitative trait locus (eQTL) mapping in translating genetic risk loci into causal mechanisms. Molecular and functional context has emerged as an important missing component of these studies, and we discuss how environmental risk factors can be modelled in a quantitative genetic context to identify disease mechanisms. In parallel, we highlight recent advances in which quantitative genetic methods establish a causal role for low vitamin D and obesity in MS, and to dissect the mechanisms through which these operate. As genetic, transcriptional, and epigenetic studies continue to expand, further mechanistic insights for MS are likely to come from the integration of genetic and environmental data."

Evidence regarding its association with multiple sclerosis (MS) remains conflicting, limited by small sample sizes. PubMed, Embase, Scopus, and Cochrane controlled register of trials (CENTRAL) were searched on September 9, 2025 without any language or time restrictions. The inclusion criteria were observational studies that evaluated the association between exposure to air pollutants and MS development or severity. Hazard ratios (HRs) with 95% confidence intervals (CIs) were pooled as effect estimates using the fixed or random effects model. Exposures included PM2.5, PM10, nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone (O3). Outcomes were MS risk and severity, including relapses, disability progression measured with the Expanded Disability Status Scale (EDSS), and contrast-enhancing lesions (CELs) development. Twenty-two studies comprising 16,585,206 participants were included. Long-term exposure to PM2.5 (HR\u2009=\u20091.21; 95% CI: 1.07-1.38), PM10 (HR\u2009=\u20091.20; 95% CI: 1.02-1.42), and CO (HR\u2009=\u20093.85; 95% CI: 1.34-11.08) were associated with increased MS risk.

This study aimed to map MS prevalence across Isfahan Province and evaluate differences by sex and urban versus rural setting, as well as to assess any association between ambient air pollution and MS prevalence. Data from 11,456 provincially registered MS patients in 28 counties in Isfahan, Iran, were examined in this cross-sectional ecological study. Official population estimates were used to calculate the county-level MS point prevalence per 100,000 population in 2023, stratified by sex. Ratios of females to males were calculated. Annual average PM\u2082.\u2085 levels for each county were obtained from state sources for the same period. MS prevalence was compared between urban and rural counties, and correlation/regression analyses were used to test associations with pollutant levels. The prevalence of MS varied widely, ranging from 322.7 in Isfahan County to 15.4 per 100,000 in rural Jarghouyeh. Although there was no significant correlation between the sex disparity and overall prevalence, females were more affected in every county (F/M ratio: 2.0-9.0).

This study was based on 907 individuals with multiple sclerosis (MS) and 907 matched controls, where the MS cases were followed longitudinally using the Swedish MS register. We demonstrate sex- and disease-specific differences in serum PFAS concentrations between individuals with MS and controls. Moreover, two OH-PCBs (4-OH-CB187 and 3-OH-CB153) are associated with an increased risk of developing multiple sclerosis, regardless of sex and immigration status. With a clinical follow-up time of up to 18 years, an increase in serum concentrations of perfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), and perfluorodecanoic acid (PFDA) decreases the risk of confirmed disability worsening in both sexes, as well as perfluoroheptanesulfonic acid (PFHpS) and perfluorononanoic acid (PFNA), only in males with MS. These results show previously unknown associations between OH-PCBs and the risk of developing MS, as well as the inverse associations between PFAS exposure and the risk of disability worsening in MS."

Mouse brain, liver, and kidney tissues were used to systematically compare the two matrix deposition methods of sublimation and spray coating in the FluoMALDI pipeline. Half of each tissue section was left uncoated as control by covering it during matrix application. Six MALDI matrices including 9-aminoacridine, norharmane, \u03b1-cyano-4-hydroxycinnamic acid, 2,5-dihydroxyacetophenone, 2,5-dihydroxybenzoic acid, or sinapinic acid were applied in equal amounts. Autofluorescence enhancements were evaluated using three fluorescence channels in the green, red, and far-red range of the spectrum, revealing matrix- and tissue-dependent fluorescence enhancement profiles. Norharmane matrix resulted in the most consistent tissue autofluorescence enhancements across deposition methods, with the highest enhancements in the green channel when applied by spray coating, and in the red and far-red channels when applied by sublimation coating. Matrix crystal size did not significantly impact the observed fluorescence enhancement effects for all six tested matrices. The two ionization modes of MALDI-1 and MALDI-2 imaging were also compared on brain, liver, and kidney tissue sections to assess lipid detection efficiency and spatial distribution in the FluoMALDI imaging pipeline. While the spatial distributions of phosphatidylethanolamine (PE) and phosphatidylcholine (PC) species were consistent across MALDI ionization modes and matrix deposition methods, lipid detection efficiency varied depending on the matrix type, matrix crystal size, tissue type, and MALDI ionization mode. Sublimation, which produced fine crystals without solvents, generally resulted in higher phospholipid detection efficiency than spray coating for lipids including PE(36:2) and PC(36:2) in both MALDI-1 and MALDI-2 imaging. These findings highlight that the matrix choice and matrix deposition method applied significantly affect tissue autofluorescence enhancement, spatial resolution, and lipid detection efficiency in MALDI-1 and MALDI-2 imaging modes, offering valuable insights for selecting optimal matrix deposition for FluoMALDI imaging based on a given study's research goals."

Predicting MS progression is challenging due to the disease's heterogeneity. This study aimed to apply Artificial Intelligence (AI) methods to investigate the association between the MS Severity Score (MSSS), which is a measure that integrates disability level and disease duration, and patients' longitudinal clinical data and environmental exposures. Methods We integrated long-term clinical records from the Mondino MS Center (Pavia, Italy) with environmental data, including air pollution and weather conditions, based on patients' residential locations. To address missing data, we applied a hybrid imputation strategy combining exponentially weighted moving average and linear mixed-effect models. Automated Machine Learning (AutoML) was used for feature selection. We evaluated multiple Deep Learning (DL) architectures, including recurrent neural network, long short-term memory, and Gated Recurrent Unit (GRU), using varying historical window lengths to predict the MSSS class at the next follow-up. Results The final retrospective dataset comprised 4022 visits from 535 MS patients. AutoML identified both clinical and environmental variables as important features for prediction. Models incorporating environmental data performed comparably to or better than those using only clinical variables. The GRU model achieved the most stable performance, with an average Area Under the Curve of 0.814 when environmental data were included with four prior visits. Moreover, SHAP-based feature importance ranked environmental variables like PM10, PM2.5, nitrogen dioxide, precipitation, and humidity among the top predictors. Conclusion Incorporating environmental exposures into DL models can improve MSSS prediction, highlighting the value of diverse real-world data for MS monitoring. Prediction performance across different historical window lengths was comparable, suggesting that using data from two prior follow-ups (approximately one year of monitoring) may be sufficient to provide clinically meaningful predictions of MS progression."

Importantly, these nongenetic factors can influence pathogenetic pathways, and some of them can be modified. Besides established MS-associated risk factors - high latitude, female sex, smoking, low vitamin D levels caused by insufficient sun exposure and/or dietary intake, and Epstein-Barr virus (EBV) infection - strong evidence now supports obesity during adolescence as a factor increasing MS risk. Organic solvents and shift work have also been reported to confer increased risk of the disease, whereas factors such as use of nicotine or alcohol, cytomegalovirus infection and a high coffee consumption are associated with a reduced risk. Certain factors - smoking, EBV infection and obesity - interact with HLA risk genes, pointing at a pathogenetic pathway involving adaptive immunity. All of the described risk factors for MS can influence adaptive and/or innate immunity, which is thought to be the main pathway modulated by MS risk alleles. Unlike genetic risk factors, many environmental and lifestyle factors can be modified, with potential for prevention, particularly for people at the greatest risk, such as relatives of individuals with MS.

Smoking is a risk factor for multiple sclerosis (MS); also, smoking has been associated with disease activity and overall prognosis for patients with MS. Cigarette smoking is an irritative agent on the lungs, in which a proinflammatory cascade starts that culminates in autoimmunity. Inflammation may increase the risk of MS in some individuals, in a process driven by antigen cross-reactivity between lung antigens and myelin antigens. Genetics plays a central role in the individual predisposition to mounting an autoimmune reaction. Also, free radicals, cyanates, and carbon monoxide in cigarette smoke may be directly toxic to neurons. Patients with MS who smoke have higher rates of disease activity, faster rates of brain atrophy, and a greater disability burden. Some of the outcomes of smoking were found to be reversible, which makes counseling key. The pathways involved in cigarette smoking should be further analyzed to understand the mechanisms whereby smoking worsens MS prognosis. The proinflammatory and neurotoxic outcomes of cigarette smoking may be shared by other environmental exposures, such as pollution and organic solvents. From a global perspective, efforts should be made to diminish the prevalence of cigarette smoking in patients with MS."

Several radiopharmaceuticals have evolved in the last two decades. We are reporting the synthesis of the amyloid imaging PET tracer fluorine-18[18F]NAV4694 in the FX2N synthesis module under GMP-compliant conditions for clinical use. The radiosynthesis was standardised in the FX2N synthesis module, and the precursor concentration was varied from 0.5 to 2.0\u00a0mg for labelling with 18F at 110\u00a0\u00b0C, with a reaction time of 5-10\u00a0min, followed by hydrolysis with 0.6\u00a0M HCl for 5\u00a0min. The final purification was standardised with various C18 cartridges to get the maximum yield. All standard quality controls were performed, along with in vivo stability. Briefly, 350\u00a0\u00b1\u00a050 MBq of the [18F]NAV4694 was injected intravenously in patients, and PET-MR imaging was performed. The images were processed, and the distribution of the tracer was visually observed in the brain. A minimum of 2\u00a0mg concentration was found to be suitable for radiolabeling at 110\u00a0\u00b0C for 10\u00a0min and purified via C18 plus long cartridge, providing the highest radiochemical yield of 13\u00a0\u00b1\u00a03\u00a0% (decay corrected). The radiochemical purity was 99\u00a0\u00b1\u00a00.5\u00a0% with a molar activity of 255\u00a0\u00b1\u00a0125 GBq/\u03bcmol. The retention time of the [18F]NAV4694 was 17.6\u00a0\u00b1\u00a00.8\u00a0min, which was consistent with the UV/Vis peak of cold NAV4694 at 17.4\u00a0\u00b1\u00a00.7\u00a0min. The residual solvents, like DMSO and ethanol, were less than the prescribed limit. The HPLC (from plasma) showed no primary metabolites in the plasma, and the stability was 96\u00a0\u00b1\u00a02\u00a0% (in vitro) and 94\u00a0\u00b1\u00a02\u00a0% (in vivo). The human biodistribution showed a rapid clearance from the blood. The visual analysis showed uptake in cortical grey matter in a positive amyloid scan and in white matter in an amyloid-negative scan. [18F]NAV4694 was successfully synthesised in the FX2N synthesis module with high radiochemical purity. It showed distinctive uptake patterns in amyloid-positive and negative scans."

While the exact molecular etiology remains complex, evidence from multiple population-based case-control studies indicates a statistically significant association between solvent exposure and MS risk. Furthermore, this relationship appears to be modified by additional risk factors, notably cigarette smoking and specific genetic alleles.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nEnvironmental exposures, including organic solvents, serve as modifiable risk factors that contribute to MS pathogenesis. These agents likely interact with the host immune system through proinflammatory pathways, potentially synergizing with genetic predisposition and other environmental triggers, such as smoking, to amplify the risk of MS development.\n\n### [INTRODUCTION & JUSTIFICATION]\nMultiple sclerosis is recognized as a complex neuroinflammatory disease resulting from the convergence of genetic susceptibility and environmental factors. Among these, organic solvents have been identified as contributors to disease risk, though determining the precise mechanisms of such environmental triggers remains a challenge. Current evidence suggests that solvent exposure acts as an irritant, potentially inducing inflammatory responses that may contribute to the loss of immune tolerance in genetically predisposed individuals. The interaction between solvent exposure and other risks, such as smoking, suggests that these environmental agents may share similar proinflammatory or neurotoxic outcomes. Despite the lack of fully elucidated causative mechanisms for every environmental factor, the cumulative evidence from longitudinal and case-control studies reinforces the association between chemical environmental exposures and MS risk.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Exposure to organic solvents is dose-dependently associated with an increased risk of MS.\n*   The association between organic solvent exposure and MS is frequently found to be dependent on concurrent smoking status.\n*   Genetic interaction analyses reveal that solvent exposure, when combined with HLA risk genes, may influence adaptive immunity.\n*   The proinflammatory and neurotoxic effects of solvents like organic compounds and particulate matter may overlap with other industrial hazards like engine exhaust.\n*   The association between solvents and MS is supported by studies in diverse populations, including those in Sweden and the UK.\n*   Despite clinical evidence, some studies on specific airborne pollutants have yielded contradictory results, highlighting the complexity of environmental epidemiological research.\n*   Methodological tools like MALDI-imaging have advanced our ability to track lipid alterations in demyelinating conditions, which may be impacted by environmental factors.\n*   Research on the exposome and potential preventative strategies highlights the importance of acting on known modifiable risk factors like smoking and environmental pollutants to protect brain health.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The transmembrane glycoprotein cluster of differentiation 44 (CD44) has been implicated in neuroinflammation, but its functional role remains unclear. Here, we examined CD44 expression and function across both non-immune-mediated and immune-mediated MS animal models, including cuprizone-induced demyelination, experimental autoimmune encephalomyelitis (EAE), and combined cuprizone/EAE (Cup/EAE), as well as in human MS tissue and cerebrospinal fluid (CSF), using immunohistochemistry, flow cytometry and enzyme-linked immunosorbent assay. CD44 expression increased in parallel with demyelination and was most pronounced in the forebrain of Cup/EAE mice, where it localized to perivascular cuffs and lesion-associated parenchyma. CD44 expression co-localized to IBA1\u207a microglia/monocytes and CD3\u207a T cells. Flow cytometry analyses revealed high CD44 expression on myeloid-derived suppressor cells and regulatory T cells, which further increased upon immune activation. On the functional level, Cd44-deficient mice exhibited exacerbated disease severity in EAE, accompanied by increased immune cell infiltration and tissue damage. In human MS samples, CD44 expression and soluble CD44 levels in CSF were significantly elevated. Notably, CD44 upregulation was also observed in other neurological disease models, including ischemic stroke and APPswe/PS1dE9 mice, a model of Alzheimer's disease. Together, these findings identify CD44 as a conserved marker of neuroinflammatory activity and a context-dependent regulator of neuroinflammation with partially protective functions, rather than an exclusively pro-inflammatory molecule, highlighting its potential relevance in MS and related neurological disorders.\n\nID: 42530042\nTitle: Evaluation of the Behavioral and Histopathological Outcomes of Two Cuprizone Administration Routes in a Mouse Model of Multiple Sclerosis.\nAbstract: The cuprizone (CPZ) model has been used to study de- and re-myelination in mice; Previous studies have used different routes for CPZ intoxication, but the results were highly variable. Here, we compared demyelination induced by the administration of 0.3% CPZ mixed with ground rodent chow and a 400 mg/kg CPZ suspension in carboxymethyl cellulose (CMC) via oral gavage in SWR/J mice. The mice were assigned into a control group, a CPZ diet group, and an oral CPZ groups (n = 6 mice/group). Rotarod, hanging wire, and open field tests were performed to evaluate locomotor activity. Histological analyses were conducted on the corpus callosum (CC) of the brain to determine myelin loss and on the liver to assess the toxicity of CPZ. The administration of CPZ with ground rodent chow significantly reduced body weight gains, grip strength, and motor coordination performance during the 5-week demyelination period. In contrast, all analyzed parameters were less different in mice receiving CPZ via oral gavage. However, both CPZ routes significantly reduced myelin content in the CC. Additionally, the oral administration of CPZ had strong effects on liver toxicity compared to that of CPZ diet feeding. This study showed that both routes of CPZ intoxication could induce reproducible and consistent demyelination changes within the CC of the mouse brain, with the CPZ diet being more effective based on all analytical parameters and having fewer toxic effects on the liver compared with oral CPZ. In conclusion, the resultsassist in the selection of a suitable multiple sclerosis (MS) model for investigating disease mechanisms and therapies.\n\nID: 42507732\nTitle: Selective GPR17 antagonism enhances structural and functional recovery in animal models of demyelination.\nAbstract: Myelination, driven by differentiation of oligodendrocyte precursor cells, is critical for metabolic and structural support and efficient axonal signal transmission in neurons. Loss of myelin is a hallmark of multiple sclerosis and other devastating demyelinating disorders. As demyelination persists, neurons become increasingly vulnerable, leading to neurodegeneration and chronic disability. Restoring myelin through endogenous repair mechanisms offers a promising therapeutic approach to mitigate progressive neuronal loss. One key regulator of myelination is the G protein-coupled receptor 17, GPR17, whose chronic upregulation in oligodendrocyte precursor cells is commonly seen with myelin injury. In line with single-nucleus transcriptomic data showing predominant expression of GPR17 in committed oligodendrocyte precursor cells, our postmortem immunohistochemical analyses of MS patient tissue revealed a significant upregulation of GPR17+/BCAS1+ oligodendrocyte precursor cells adjacent to and in demyelinated lesions. Importantly, remyelinated lesions lacked GPR17 immunoreactivity, consistent with a model in which sustained GPR17 expression is associated with demyelination and impaired oligodendrocyte precursor cell differentiation. To test the impact of pharmacological GPR17 inhibition on remyelination, we evaluated the effects of a novel, selective GPR17 antagonist in cuprizone-induced murine demyelination models. This toxin-induced approach has been widely used to study mechanisms of de- and remyelination, in the absence of the full inflammatory complexity of demyelinating diseases such as multiple sclerosis. We show that oral treatment results in robust functional recovery consistent with remyelination, as evidenced by improved spatial memory and recovery of visual evoked potential latency delays. GPR17 antagonism also accelerated structural remyelination in the corpus callosum and optic nerve. Together, these findings support a role for pharmacological GPR17 antagonism in promoting remyelination and highlight this G protein-coupled receptor as a promising therapeutic target for demyelinating disorders.\n\nID: 42506315\nTitle: Nabiximols in Multiple Sclerosis: Beyond Spasticity-An Exploratory Systematic Review and Meta-Analysis of Symptomatic Outcomes.\nAbstract: Background/Objectives: Nabiximols, a standardized extract of Cannabis sativa, has been approved as an add-on therapy for patients with moderate to severe spasticity associated with multiple sclerosis (MS). Moreover, current Italian treatment algorithms suggest that cannabis-based therapies may have further relevance in the management of MS. The aim of our systematic review and meta-analysis was to assess the effectiveness of nabiximols in relieving symptoms other than spasticity in adult MS patients. Methods: A systematic search was conducted in Web of Science, MEDLINE (via PubMed), Cochrane CENTRAL and Embase on September 10, 2025. Study selection was performed according to the predefined PROSPERO protocol (CRD42022329952). Data were combined into a common denominator and examined using a random-effects model with meta-regression expressed as mean difference (MD) and a 95% confidence interval (CI). Risk of bias was assessed using the Cochrane risk of bias instrument (RoB2) and the Risk Of Bias In Non-randomized Studies of Interventions (ROBINS-I) tool. Results: Of the 49 eligible articles, 25 were included in the statistical analysis (2949 patients). Significant improvements in spasm quality (MD = -16.87; 95% CI = (-29.75)-(-3.99)), bladder function (MD = -16.38; 95% CI = (-22.18)-(-10.58)), sleep disruption (MD = -15.75; 95% CI = (-22.02)-(-9.49)) and gait function (timed walk MD(s) = -5.31; 95% CI(s) = (-9.88)-(-0.74)) were observed. Time-dependency was not significant. The subject global impression of change (SGIC) improved significantly after the first month (odds ratio (OR) = 1.69; 95% CI = (1.30)-(2.18)). Conclusion: Beyond spasticity, nabiximols may represent a signal of benefit for bladder function, sleep disruption, spasm quality, and gait function in MS, in line with the \"spasticity-plus\" concept. However, the evidence certainty was low to very low, and these findings should be considered exploratory.\n\nID: 42467616\nTitle: A high-resolution phenotypic screen identifies regulators of CNS axon diameter in zebrafish.\nAbstract: The molecular mechanisms underpinning neuronal morphogenesis remain to be fully understood. A powerful step in uncovering the molecular basis of biological processes is the execution of discovery screens in model systems. Here, we employed zebrafish to identify molecules that regulate axon diameter in the central nervous system. Axon diameter can vary by >100-fold, with larger axons exhibiting faster conduction velocity. Axon diameter influences myelination, can be dynamically regulated, and is altered in disease. However, gaining insights into axon diameter has been challenging due to the small size and complexity of axons in vivo. Therefore, we developed an automated high-resolution live imaging and analysis screening platform to identify pharmacological modulators of the diameter of the large Mauthner axon in zebrafish. We screened 880 compounds and identified 33 hits. Validating this pipeline, we confirmed that compounds affecting beta-2 adrenoceptor and dopamine signaling increase axon diameter. This represents the first subcellular in vivo imaging-based screen to detect changes in axon diameter, providing entry points to study the biology of this key feature of neuronal morphology.\n\nID: 42447923\nTitle: Effect of nerolidol on seizure and oxidative brain damage induced by pentylenetetrazole in mice.\nAbstract: Nerolidol, a natural sesquiterpene alcohol found in essential oils, has demonstrated antioxidant, anti-inflammatory, and neuroprotective properties. However, its effects on pentylenetetrazole (PTZ)-induced seizure and associated oxidative brain damage remain unclear. To evaluate the anticonvulsant effects of nerolidol on PTZ-induced seizures in mice and to investigate its impact on oxidative and nitrosative stress markers in the hippocampus and cortex. Male mice were divided into 5 groups: control, PTZ, and PTZ pretreated with nerolidol (25, 50, or 100\u2009mg/kg, orally) 30\u2009minutes before PTZ administration. Seizure activity was assessed by measuring latencies to minimal clonic seizures (MCSs) and generalized tonic-clonic seizures (GTCSs). After a behavioral evaluation, hippocampal and cortical tissues were analyzed for malondialdehyde (MDA), nitric oxide (NO) metabolites, superoxide dismutase (SOD), catalase (CT), and total thiol content. Nerolidol significantly increased MCS and GTCS latencies compared with the PTZ group. In the hippocampus, all doses reduced MDA levels, while in the cortex this effect was observed at 50 and 100\u2009mg/kg. Nitric oxide metabolites were decreased by the two higher doses in both brain regions. The PTZ-induced reductions in SOD and CT activities were reversed by nerolidol at all doses, and total thiol levels were restored at 50 and 100\u2009mg/kg. Nerolidol exhibits anticonvulsant and neuroprotective effects on PTZ-induced seizures, likely mediated by reduced oxidative and nitrosative stress and enhancement of endogenous antioxidant defenses.\n\nID: 42443579\nTitle: Eriochrome Cyanine R revisited: a standardized myelin stain protocol for thick sections of the central & peripheral nervous system across species, pathologies and disease models.\nAbstract: Myelin enables rapid action potential conduction and axonal support, and its disruption underlies diverse neurological disorders. Its assessment is essential for studying development, plasticity, and repair of the nervous system (NS), and for diagnosing demyelinating diseases and evaluating remyelination therapies. Multiple histological methods detect myelin, each with trade-offs in sensitivity, cost, and reproducibility. Among them, Eriochrome Cyanine R (EC-R) is a simple, affordable myelin stain widely used in thin sections, but remains poorly standardized, and underexplored in thick vibratome sections. Here we describe and validate a simple, inexpensive, solvent-free EC-R protocol for central and peripheral nervous system tissue across seven vertebrate species and multiple demyelinating conditions. The method replaces subjective microscopic differentiation with fixed, time-controlled incubations scaled to section thickness, improving reproducibility. Using perfusion and immersion-fixed samples, we show that the protocol yields homogeneous myelin labeling with sharp white/gray matter contrast in whole brains, cortical slabs, spinal cord, and peripheral nerves. Thick sections stained with EC-R preserve 3-dimensional tissue architecture, resolve single myelinated axons and intracortical bands, and can be combined with Nissl-like counterstains and immunohistochemistry. Developmental series in neonatal rats reveal expected PNS-CNS myelination gradients, while experimental demyelination models and naturally occurring diseases (canine distemper and human multiple sclerosis) illustrate the method's ability to delineate lesion cores, perilesional gradients, and associated glial and immune activation. This standardized EC-R approach provides a robust and versatile tool for comparative neuroanatomy, experimental neuropathology, and translational studies of myelination, demyelination, and remyelination, as well as for the clinical diagnosis of myelin-related disorders.\n\nID: 42431827\nTitle: Lifetime exposure to shift work and risk of multiple sclerosis: retrospective and prospective cohort studies in UK Biobank.\nAbstract: Multiple sclerosis (MS) is an autoimmune disease with complex aetiology involving genetic, environmental and lifestyle factors. Shift work disrupts circadian rhythms and is a potential occupational risk factor for MS, with exposure before age 20 thought to be of additional risk. To investigate associations between retrospective lifetime shift work exposure and MS diagnosis and between prospective shift work exposure and incident MS over 13 years of follow-up in the UK Biobank cohort. Participants that were in work and free of MS at baseline were followed up for 13 years, and lifetime exposure to night, day and mixed shift work was assessed in a subset of participants. Logistic regression and Cox proportional hazard models were applied to test associations between shift work and MS diagnosis, controlling for demographic and lifestyle confounders. Lifetime exposure to mixed, day or night shift work was not associated with an increased risk of MS diagnosis. No significant associations were observed for early-life shift work exposure or in prospective analysis of those reporting shift work at baseline. Factors such as female sex, smoking, childhood obesity and reduced sunlight exposure were consistently associated with higher MS risk. There was no evidence for an association between shift work and the risk of MS diagnosis in this cohort, in retrospective analysis of lifetime exposure or in prospective studies of shift work at baseline following 13 years of follow-up. Further research is needed to elucidate mechanisms and latitudinal variations in shift work-related MS risk.\n\nID: 42420066\nTitle: Association of long-term outdoor air pollution exposure with incidence of Parkinson's disease, multiple sclerosis and motor neuron diseases: a systematic review and meta-analysis.\nAbstract: Parkinson's disease (PD), multiple sclerosis (MS) and motor neurone disease (MND) are progressive and debilitating diseases that are increasing in prevalence globally. Some primary studies show an increased risk from long-term outdoor air pollution exposure, while others contradict this association. A systematic review and meta-analysis were undertaken to assess the associations of long-term (\u22651 year) outdoor air pollution exposure with PD, MS and MND incidence. We searched eight databases for publications up to July 2025. Primary case-control, cohort, cross-sectional or ecological studies investigating the association between long-term air pollution exposure and adult (>18\u00a0years old) PD, MS, or MND incidence were included. Meta-analyses were carried out using random-effects models with assessment of heterogeneity, meta-bias and shape of the exposure-response functions. PROSPERO (CRD42023417961). Of 42 papers included, 26, 3 and 3 were meta-analysed for PD, MS, and MND outcomes, respectively. 19 studies from North America, 12 from Europe and 10 from Asia were meta-analysed. For every 5\u00a0\u03bcg/m3 and 15\u00a0\u03bcg/m3 increase of Particulate Matter 2.5 (PM2.5) and PM10 concentration, estimated (95% Confidence Interval) PD risk was 10% (1.10; 1.03-1.19) and 18% (1.18; 1.01-1.38), respectively but effects varied across settings (Prediction Interval: 0.80-1.52 for PM2.5 and 0.41-3.36 for PM10), with the largest estimated risk for PM2.5 in Asia (1.19; 1.01-1.41). There was no clear evidence that PM2.5 (1.01; 0.77-1.32) or nitrogen dioxide (NO2, 0.98, 95% CI: 0.95-1.01) were associated with MS risk or PM2.5 with MND risk (1.07, 95% CI: 0.86-1.33). This systematic review reports increased PD risk from long-term PM2.5 and PM10 exposure. No association was observed for MS and MND from a very limited evidence base. The neurodegenerative diseases investigated here are rare and therefore alternatives to insufficiently powered cohort studies are needed to strengthen the evidence on risk.\n\nID: 42401247\nTitle: Panax quinquefolius saponins promote remyelination via orchestrating HMGCS1-NPC1-MAL-mediated lipid metabolism and rebalancing JAK-STAT signaling in a cuprizone-induced demyelination model.\nAbstract: Panax quinquefolius L. is traditionally used as a \"Qi-tonifying and Yin-nourishing\" herb for weakness and limb flaccidity, symptoms described as \"Feng fei\" or flaccidity syndrome. These manifestations partially resemble motor dysfunction in multiple sclerosis (MS). Panax quinquefolius Saponins (PQS), are major bioactive constituents, but their effects on demyelination and related molecular changes remains unclear. To investigate the effects of PQS on demyelination and explore associated changes in inflammatory signaling and lipid metabolism. PQS was qualitatively profiled by UPLC-QTOF-MS and quantitatively standardized by HPLC-DAD. Male C57BL/6N mice were randomly divided into six groups (n\u202f=\u202f12-16/group): Control, Model (daily intragastric administration of 330\u202fmg/kg of cuprizone (CPZ) for 6 weeks), Positive control (10\u202fmg/kg of Clemastine), and low-, medium-, and high-dose PQS groups (25, 50, or 100\u202fmg/kg). During week 2-6, mice received drugs by daily intragastric administration. Behavioral assessments including pole test, rotarod, and open field test were performed. Myelin integrity and related molecular changes were evaluated by histological staining, immunofluorescence (IF), transcriptomics, Western blotting, and molecular docking. PQS ameliorated CPZ-induced motor dysfunction in behavioral assessments (P\u202f<\u202f0.05). PQS also attenuated myelin loss in the corpus callosum (CC), with the high-dose group increasing myelinated areas to approximately 74% of control levels (P\u202f<\u202f0.01). Transcriptomic and protein analyses showed that PQS downregulated JAK1/STAT3/NLRP3 inflammatory pathway. In parallel, the HMGCS1-NPC1-MAL axis was upregulated, accompanied by increased mevalonate (MVA) and total cholesterol (TC) levels (P\u202f<\u202f0.05) and reduced PLIN2 expression (P\u202f<\u202f0.001), suggesting decreased lipid droplet accumulation and altered cholesterol metabolism.Molecular docking predicted ginsenosides Rb3, Rk3, Re, Rc, Ro, and Rf may interact with targets related to inflammatory and lipid metabolism. PQS supported myelin restoration, which is correlated with a modulation of the JAK-STAT signaling pathway and HMGCS1/NPC1-associated lipid homeostasis. PQS may represent a potential therapeutic lead for demyelinating diseases, although mechanisms require further validation.\n\nID: 42400730\nTitle: Neuroprotective potential of resveratrol in Parkinson, Huntington, amyotrophic lateral sclerosis, and multiple sclerosis: a comprehensive review.\nAbstract: Resveratrol shows neuroprotective effects in preclinical studies across a number of neurodegenerative illnesses, including Parkinson's disease (PD), Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), and Huntington's disease (HD), and it enhances mitochondrial function through stimulation of the AMPK/SIRT1/PGC-1\u03b1 pathway, thereby improving mitochondrial oxidative capacity and ATP generation. The natural polyphenol lowers \u03b1-synuclein accumulation and affects autophagy; both markers of PD. Combining nano\u2011resveratrol formulations with L\u2011DOPA has shown greater therapeutic efficacy in animal models (MPTP mouse), while co\u2011administration with EGCG has shown synergistic neuroprotection in vitro (SH\u2011SY5Y cells). These combination strategies offer potential advantages in neuroprotection and symptom alleviation while minimizing adverse drug effects. Resveratrol activates SIRT1 and AMPK signaling in preclinical models, enhancing mitochondrial biogenesis, lowering apoptosis, and restoring cellular resilience. The effectiveness of various models and dosages varies. The primary mechanism by which resveratrol promotes neuronal survival and remyelination in multiple sclerosis is through SIRT1 activation, which does not directly reduce inflammation. As innovative delivery systems, intranasal nanoparticles and exosomes produced from macrophages have shown improved CNS targeting accuracy. Resveratrol slows down neurodegeneration and improves the prognosis of HD by improving motor function and stimulating mitochondrial biogenesis in addition to activating neuroprotective ERK signaling. All of these results point to resveratrol's several pathways as a strong contender for neurodegenerative disease adjunctive treatment. The current evidence base is insufficient to support clinical use of resveratrol for any of the four diseases. Further rigorous preclinical studies (including TDP-43 models for ALS, SIRT1 knockout studies, and human-feasible dosing) and well-designed clinical trials with pharmacokinetic endpoints are required before any clinical recommendations can be made.\n\nID: 42392741\nTitle: [Dihydroartemisinin ameliorates inflammation in experimental autoimmune encephalomyelitis by enhancing AXL signaling in microglia].\nAbstract: This study aimed to investigate the mechanism of dihydroartemisinin(DHA) in ameliorating multiple sclerosis(MS). Hematoxylin and eosin(HE) staining was used to assess inflammatory cell infiltration, while luxol fast blue(LFB) staining and electron microscopy were performed to evaluate myelin sheath structure. In cell experiments, this study measured programmed cell death ligand 1(PD-L1) expression on BV2 cells and forkhead box protein p3(Foxp3) expression in Jurkat T cells co-cultured with BV2 cells, determined the C-C motif chemokine ligand 5(CCL5) concentration in the supernatant of BV2 cells, and evaluated BV2 cell chemotaxis. Western blot(WB) was performed to detect protein levels of receptor tyrosine kinase(AXL), phosphorylated AXL(p-AXL), signal transducer and activator of transcription 1(STAT1), phosphorylated STAT1(p-STAT1), and suppressors of cytokine signaling 3(SOCS3). To confirm the role of AXL, key cellular assays were repeated following inhibition of AXL. Additionally, under physiological conditions, the effects of DHA on body weight, spleen weight, and peripheral blood immune cell profiles were examined. The results showed that DHA significantly reduced disease scores, attenuated body weight loss, suppressed inflammatory infiltration, and promoted myelin sheath repair in experimental autoimmune encephalomyelitis(EAE) mice. At the cellular level, DHA upregulated PD-L1 expression on BV2 cells and Foxp3 expression in co-cultured Jurkat cells, and inhibited CCL5 release and BV2 cell chemotaxis. It also upregulated AXL, p-AXL, p-STAT1, and SOCS3 protein expression in BV2 cells. When AXL was inhibited, these effects are nullified. In healthy mice, DHA did not have any effect on their various parameters. In conclusion, DHA maintains inflammatory homeostasis in the EAE model by activating the AXL signaling pathway in microglia.\n\nID: 42387200\nTitle: Tetrahydrocannabinol/cannabidiol in the treatment of restless legs syndrome.\nAbstract: Dopamine agonists were previously considered the first-line treatment for Restless Legs Syndrome (RLS); however, \u03b12\u03b4 ligands are now recommended to prevent augmentation. As cannabinoids inhibit glutamate release in the striatum, they may represent an effective therapeutic option for RLS. Evaluate the efficacy of 2.7\u00a0mg \u03949Tetrahyedrocannabinol/2.5\u00a0mg Cannabidiol (2.7mgTHC/2.5mgCBD) in RLS. This is an exploratory, prospective, 3-month open-label trial. At baseline, patients underwent blood testing, respiratory polygraphy, and a 14-day actigraphy. Treatment was initiated at baseline, with dose titration at week 4 if required. The Expanded Disability Status Scale (EDSS), Epworth Sleepiness Scale (ESS), International Restless Legs Syndrome Rating Scale (IRLS), Modified Ashworth Scale, and EQ-5D were assessed at baseline and at weeks 4 and 12. The 14-day actigraphy was repeated at week 12. The primary endpoint was improvement in IRLS scores. Sleep parameters were evaluated as secondary endpoints. Primary end point: improvement in IRLS. Sleep parameters were secondary end points. Eighteen patients with RLS were included, of whom 16 had multiple sclerosis (MS). The cohort comprised 55.5% women, with a mean age of 51.87\u00a0years, a median EDSS score of 2, and a mean Ashworth score of 1\u2009\u00b1\u20091.19. Median iron metabolism parameters were within the normal range. At baseline, patients exhibited low daytime sleepiness (ESS: 10.63\u2009\u00b1\u20093.46) and severe RLS (IRLS: 22.44\u2009\u00b1\u20098.77). Mean sleep efficiency (SE) was 83.64\u2009\u00b1\u20096.03%, sleep latency (SL) was 26.71\u2009\u00b1\u200918.64\u00a0min, and wake after sleep onset (WASO) was 40.29\u2009\u00b1\u200910.03\u00a0min. IRLS scores improved significantly after both 1 month and 3 months of treatment (p\u2009<\u20090.001). WASO was significantly reduced (p\u2009=\u20090.015), whereas no significant changes were observed in SL or SE. After 1\u00a0year, 66.66% of patients remained on treatment and continued to show sustained improvement in IRLS scores (p\u2009=\u20090.000). In this exploratory open-label study, treatment with 2.7\u00a0mg THC/2.5\u00a0mg CBD was effective in reducing RLS severity, as measured by the IRLS scale, in patients with MS and-associated idiopathic RLS. Improvements were observed after 1 and 3 months of treatment and were maintained after 1\u00a0year among patients who continued therapy.\n\nID: 42370465\nTitle: Evaluating the effectiveness of simvastatin in slowing the progression of disability in secondary progressive multiple sclerosis: a synopsis of MS-STAT2, a multicentre, randomised controlled, double-blind, phase 3 clinical trial.\nAbstract: Despite the relative success of immuno-modulatory disease-modifying therapy in relapsing remitting multiple sclerosis, progressive worsening of disability remains a major problem, particularly for those with secondary progressive multiple sclerosis. Various underlying mechanisms are likely to contribute, augmented by comorbidities (such as vascular risk) and ageing. In the phase 2b MS-STAT trial, simvastatin (80\u2005mg) (Sandoz Ltd, Camberley, UK) reduced the mean annualised whole brain atrophy rate by 43% compared to placebo in patients with secondary progressive multiple sclerosis (p\u2005=\u20050.003). We now report the phase 3, MS-STAT2 trial, with confirmed progression of disability as the primary outcome. A multicentre, phase 3, randomised, double-blind, placebo-controlled clinical trial was conducted at 31 UK neuroscience centres and district general hospitals. Secondary progressive multiple sclerosis participants aged 18-65 years were randomised 1\u2005:\u20051 to oral simvastatin (80\u2005mg), or matched placebo, based on a minimisation algorithm that incorporated the following factors: sex (male/female); age (< or \u2265\u200545 years); Expanded Disability Status Scale baseline score (\u2264\u20055.5 or \u2265\u20056); whether participants were taking newly licensed (2017 onward) disease-modifying treatments for secondary progressive multiple sclerosis; and trial site. An independent and secure online randomisation service was used. All participants, site investigators and the trial co-ordinating team were blinded to treatment allocation. The Expanded Disability Status Scale was measured every 6 months and was compared to baseline scores, with remote data collection used when enforced by the COVID-19 pandemic. The primary outcome was time to Expanded Disability Status Scale-confirmed disability progression. Progression of disability was defined as an increase of at least one point on the Expanded Disability Status Scale if the baseline score was <\u20056, or an increase of 0.5 point if the baseline score was \u2265\u20056. The initial disability progression event was finalised as confirmed if the increase in Expanded Disability Status Scale score persisted at the next assessments \u2265\u20056 months later. Follow-up was for 36 months, or 54 months, for those without confirmed disability progression at 36 months who agreed to enter an optional blinded extension. An intention-to-treat analysis was carried out. The study was conducted between 10 May 2018 and 26 July 2024. There were 964 participants randomised, with 482 in the placebo group and 482 in the simvastatin group. 173 (35.9%) participants in the placebo group and 192 (39.8%) participants in the simvastatin group experienced Expanded Disability Status Scale-confirmed disability progression (adjusted hazard ratio =\u20051.13, 95% confidence interval 0.91 to 1.39, p\u2005=\u20050.263). No material differences in the secondary outcomes were observed. No major safety issues were seen. The MS-STAT2 trial did not demonstrate a treatment effect of simvastatin in slowing disability progression in participants with secondary progressive multiple sclerosis. Despite the favourable outcomes of the previous phase 2b trial, simvastatin use in secondary progressive multiple sclerosis should be confined to existing vascular indications. This synopsis presents independent research funded by the National Institute for Health and Care Research (NIHR) Health Technology Assessment programme as award number 15/57/143. Multiple sclerosis is a lifelong condition that affects the brain and spinal cord. Many people with multiple sclerosis start with a type called relapsing-remitting multiple sclerosis, which can later become secondary progressive multiple sclerosis. Secondary progressive multiple sclerosis causes steady worsening of disability over time, and currently, there are very few treatment options for people without signs of active inflammation. Simvastatin is a cholesterol-lowering drug (a statin) that is widely used for heart disease. Earlier research (the Simvastatin in Secondary Progressive Multiple Sclerosis phase 2 trial) suggested that high-dose simvastatin might slow brain shrinkage and disability in people with secondary progressive multiple sclerosis. To test this further, researchers ran a large phase 3 clinical trial called Simvastatin in Secondary Progressive Multiple Sclerosis (phase 3 trial), involving 964 participants across the United Kingdom. Half were given simvastatin and half a placebo, and they were followed up while continuing to take these for 3 years. For participants whose disability was stable at 3 years, they could continue in the trial on the same medication for up to 4.5 years if they were happy to do so. The main aim was to see if simvastatin could slow down worsening disability, which was measured using a scale called Expanded Disability Status Scale. The Expanded Disability Status Scale data were mainly collected at face-to-face appointments, but some assessments were conducted by telephone when enforced by the COVID-19 pandemic. The results showed no significant difference between the simvastatin and placebo groups. Simvastatin did not delay disability progression. The trial also looked at other outcomes such as walking speed, hand function, memory and quality of life. Again, there were no meaningful differences. Importantly, simvastatin was generally safe, and side effects were rare. The trial also found that people with higher disability levels faced higher personal and financial costs, and many relied on unpaid care from family or friends. Overall, the Simvastatin in Secondary Progressive Multiple Sclerosis phase 3 trial provides clear evidence that simvastatin does not have a therapeutic effect in slowing disability progression in people with secondary progressive multiple sclerosis. It also offers valuable insights for future research into progressive multiple sclerosis and highlights the need for new treatments that target the disease\u2019s underlying causes.\n\nID: 42364973\nTitle: PBPK Modeling and Clinical Data Reveal Reduced Impact of CYP3A4 and CYP2C9 Inhibitors on Elimination of Siponimod.\nAbstract: Multiple sclerosis (MS) is a significant cause of neurological disability in young adults. Siponimod, a potent sphingosine-1-phosphate (S1P) receptor modulator, is used to treat MS by reducing T-cell recirculation and central inflammation. The presented work includes clinical data describing the impact of the CYP3A4 inhibitor clarithromycin on siponimod metabolism and the results of updated physiologically based pharmacokinetic (PBPK) modeling. A clinical drug-drug interaction (DDI) study assessed the effect of clarithromycin on siponimod pharmacokinetics in healthy participants with the CYP2C9*1*3 genotype. Results revealed minimal differences in PK: a 2% increase in Cmax, an 8% increase in AUClast and a 9% increase in AUCinf, confirming no clinically relevant drug-drug interaction (DDI). The existing siponimod PBPK model was updated using these DDI study data, estimating a CYP3A4 fraction metabolized of 6.4% in the CYP2C9*1*1 genotype. Simulations using the updated PBPK model in the absence and presence of the restricted co-medication (CYP2C9 and CYP3A perpetrators) were conducted. There was no clinically relevant DDI with moderate and strong CYP3A4 inhibitors across CYP2C9 genotypes with a predicted maximum net AUC increase of 1.33. Co-administration of fluconazole, a moderate CYP3A4 and CYP2C9 inhibitor, was predicted to result in <\u20092-fold net AUC increase, except for the genotype CYP2C9*2*2, where a 2.2-fold net AUC increase compared to the CYP2C9 wild type without fluconazole co-treatment was observed. Siponimod Cmax and AUC were comparable across CYP2C9 genotypes during dose titration in the absence or presence of fluconazole, suggesting no impact on the effectiveness of the dose titration regimen.\n\nID: 42356263\nTitle: The Effect of Polyphenol Supplementation in People with Multiple Sclerosis: A Systematic Review of Clinical Trials.\nAbstract: Background/Objectives: Multiple sclerosis (MS) is an autoimmune neuroinflammatory disease affecting 2.9 million worldwide. Current immunosuppressive treatments offer limited neuroprotection and often cause adverse effects. Polyphenols with antioxidant and anti-inflammatory properties have been investigated as adjuncts in MS. Methods: On 19 June 2025, Embase, Medline, and ClinicalTrials.gov were systematically searched. Eligible clinical trials assessing polyphenol supplementation in MS were included. Outcomes of interest were Expanded Disability Status Scale (EDSS), annualised relapse rate (ARR), magnetic resonance imaging (MRI) changes, safety, and tolerability. Risk of bias was evaluated using the Cochrane tool, and certainty of evidence was appraised with Grading of Recommendations Assessment, Development, and Evaluation (GRADE). The protocol was registered with PROSPERO (CRD420251052042). Results: Of 870 records identified, 13 trials (n = 785) met inclusion. Nanocurcumin consistently improved EDSS in relapsing-remitting MS (3 trials, n = 150; p = 0.039-0.041), while epigallocatechin-3-gallate, silymarin (SM), cranberry extract, and bio-enhanced curcumin extract (BCM-95) curcumin showed no significant impact on disability, relapse rates, or MRI outcomes. Intervention adverse events were generally mild. SM showed potential hepatoprotective effects. Risk of bias was determined as low risk for seven of the trials and of some concern for five of the studies. Most often raising concerns because of selective reporting. Certainty of evidence, assessed using GRADE, was generally moderate, indicating some uncertainty regarding the outcomes. Meta-analysis was not possible due to the heterogeneity of included studies. Conclusions: Nanocurcumin may contribute to improvements in disability outcomes in Relapse Remitting Multiple Sclerosis (RRMS), whereas other polyphenols lack consistent efficacy. However, the evidence base remains limited by small sample sizes and methodological concerns. Larger, multicentre randomised controlled trials are required to establish optimal dosing, long-term safety, and therapeutic potential.\n\nID: 42343001\nTitle: Therapeutic evaluation of artocarpin-enriched extract from Artocarpus heterophyllus heartwood in multiple sclerosis rat model.\nAbstract: Neuro-inflammation leads to the development of neurological disorders such as multiple sclerosis (MS) by promoting demyelination in Central nervous system (CNS). Due to limitations in the efficacy and side effects of the currently available treatments of MS this study is designed to explore neuroprotective role of artocarpin enriched extract (AEE) of Artocarpus heterophyllus heartwood as a favorable natural therapeutic substitute in MS. AEE was prepared from the heartwood of A. heterophyllus using a green microwave-assisted extraction technique. To assess the safety profile of AEE acute toxicity assessment was performed in accordance with OECD guidelines. Molecular docking analysis was performed to analyze the binding affinity and interaction behavior of artocarpin against multiple therapeutic targets S1PR1, MMP-9, BTK, IL-17, TNF-\u03b1 and NLRP3. For the therapeutic evaluation of AEE, in cuprizone (CPZ) induced demyelination, forty-two Wistar albino rats were selected and evenly distributed into seven groups: Normal control (NC), disease control (DC), standard treatment drug (fingolimod, 15\u00a0mg/kg, pure artocarpin (AC) 100\u00a0mg/kg and three treatment groups receiving AEE at dose of 200\u00a0mg, 400\u00a0mg, and 800\u00a0mg/kg. Neuroinflammation was induced in all groups except NC by administering 0.2% w/w 450\u00a0mg/kg cuprizone for 42 days. Behavioral assessments, biochemical analyses, histopathological examinations, gene expression and neurotransmitter level were observed to explore the meyelin protection effects of AEE. Results demonstrated that pure artocarpin and AEE produced significant effects in the protection of neuron myelin sheath and can be considered as a suitable therapeutic agent for further study in MS.\n\nID: 42329180\nTitle: Growth Differentiation Factor 11 Is a Circulating Regulator of Oligodendrocyte Differentiation and CNS Myelin Formation and Repair.\nAbstract: Remyelination failure is a major contributor to progressive neurological disability in multiple sclerosis (MS). Although oligodendrocyte progenitor cells (OPCs) persist in demyelinated lesions, they often fail to differentiate into myelinating oligodendrocytes. This study aimed to determine whether growth differentiation factor 11 (GDF11), a circulating member of the TGF-\u03b2 superfamily, regulates oligodendrocyte differentiation, CNS myelination, and remyelination. The effects of GDF11 were examined using purified mouse OPC cultures, a neonatal developmental myelination model, and two demyelination models: cuprizone-induced demyelination and experimental autoimmune encephalomyelitis (EAE). OPC differentiation was assessed by immunocytochemistry and morphological analysis. In\u00a0vivo myelination and remyelination were evaluated using histological, ultrastructural, and behavioral approaches following systemic GDF11 administration. GDF11 directly promoted OPC differentiation and maturation in\u00a0vitro without affecting proliferation. Systemic GDF11 enhanced developmental myelination in neonatal mice, increasing myelin gene expression, myelinated axon density, and myelin thickness. Although GDF11 did not prevent active demyelination, it significantly accelerated remyelination and functional recovery following cuprizone withdrawal and in the EAE model, and this was accompanied by enhanced oligodendrocyte differentiation and reduced neuroinflammation. These findings identify GDF11 as a circulating regulator of oligodendrocyte maturation and CNS myelin formation and repair, highlighting its therapeutic potential for demyelinating diseases.\n\nID: 42292352\nTitle: Disease outcomes with ublituximab in treatment-na\u00efve participants: subpopulation analyses of the phase 3 ULTIMATE I and II studies in participants with relapsing multiple sclerosis.\nAbstract: Evidence suggests that treating relapsing multiple sclerosis (RMS) initially with a high-efficacy disease-modifying therapy (DMT) is superior to an escalating approach at reducing disability progression and relapse rate. To evaluate the efficacy of ublituximab versus teriflunomide in participants without prior DMT (treatment-na\u00efve population) and in a subset of treatment-na\u00efve participants with symptom onset \u2264 three years (early treatment subpopulation). Pooled post hoc analyses of ULTIMATE I/II were conducted at Week 96. The annualized relapse rate was 0.081 for ublituximab (n =\u00a0345) versus 0.188 for teriflunomide (n =\u00a0377) (p <\u00a00.001) in the treatment-na\u00efve population and 0.130 for ublituximab (n =\u00a0139) versus 0.334 for teriflunomide (n =\u00a0140) in the early treatment subpopulation (p =\u00a00.004). Twelve-week confirmed disability improvement rates were 10.7% versus 5.3% (p =\u00a00.010) in the treatment-na\u00efve population and 14.4% versus 3.6% (p =\u00a00.002) in the early treatment population (ublituximab vs. teriflunomide). Significant reductions in gadolinium-enhancing T1 lesions and new/enlarging T2 lesions, respectively, occurred for ublituximab versus teriflunomide (treatment na\u00efve: 0.031 vs. 0.791 and 0.390 vs. 4.144; p\u00a0<\u00a00.001 for both; early treatment: 0.051 vs. 1.030 and 0.508 vs. 6.068; p\u00a0<\u00a00.001 for both). Ublituximab was associated with significant treatment benefits at Week 96 in treatment-na\u00efve participants and those receiving treatment within three years of symptom onset. https://clinicaltrials.gov/study/NCT03277261 and https://clinicaltrials.gov/study/NCT03277248, identifiers NCT03277261 and NCT03277248.\n\nID: 42274557\nTitle: Quantitative Assessment of GFAP-Based Astrocyte Morphology in the Cuprizone Model: A Comparative Evaluation of Neurolucida\u00ae 360 and SNT.\nAbstract: Reactive astrocytes are a hallmark of several neurological diseases in multiple sclerosis and experimental demyelination models. Their morphological alterations are commonly assessed by qualitative histopathology, yet quantitative tools are required to better capture astrocytic heterogeneity and to allow correlations with imaging-derived biomarkers. Here, we present a workflow for the quantitative analysis of Glial Fibrillary Acidic Protein (GFAP) network remodeling in astrocytes in the cuprizone model of demyelination. C57BL/6 mice were intoxicated with cuprizone for 3 or 5 weeks to induce progressive demyelination, microglial activation, and reactive astrogliosis. Brain sections were processed for anti-GFAP immunohistochemistry, and individual astrocytes from the stratum oriens of the hippocampus were digitally reconstructed. Diverse parameters of GFAP topology, including soma size, process length, branching order, convex hull area, and ramification index, were extracted using either the commercial Neurolucida\u00ae 360 software or the open-source Simple Neurite Tracer (SNT) plugin in ImageJ. Principal component analysis revealed clear differences between control astrocytes and astrocytes in cuprizone-intoxicated animals, with reactive astrocytes displaying increased numbers of primary processes, enhanced bifurcation, and process complexity. Comparative evaluation of Neurolucida\u00ae 360 and SNT demonstrated that both tools are suitable for astrocyte reconstruction, although Neurolucida\u00ae 360 enabled faster and more detailed tracing. This protocol provides a reproducible pipeline for the quantitative assessment of astrocyte morphology under control and pathological conditions, thereby supporting future efforts to link cellular remodeling to functional outcomes in neuroinflammatory disease models.\n\nID: 42257510\nTitle: Progression to Wheelchair in Secondary Progressive Multiple Sclerosis and Impact of Siponimod: Post Hoc Analyses From the EXPAND Study.\nAbstract: Delaying time to requiring a wheelchair in people living with MS is an important treatment goal to maintain quality of life and guard against increased healthcare costs. In this post hoc analysis, the effects of siponimod versus placebo on time to sustained Expanded Disability Status Scale (EDSS) \u2265\u20097.0 over the core part of the Phase 3 EXPAND study were assessed. The time to sustained EDSS \u2265\u20097.0 (time to requiring a wheelchair) was analysed for participants with secondary progressive multiple sclerosis (SPMS). Analyses were based on a While on Treatment (WOT) set that censored participants if entering open-label treatment. Subgroup analyses were conducted in participants with active versus non-active SPMS (defined based on pre-study/baseline criteria), and in participants with baseline EDSS 6.5. In the overall EXPAND population, siponimod reduced the risk of reaching sustained EDSS \u2265\u20097.0 (requiring a wheelchair) by 40% (hazard ratio [HR], 0.60; 95% confidence interval [CI], 0.41-0.88; p\u2009=\u20090.009) versus placebo; the reduction in risk was 51% (HR, 0.49; 95% CI, 0.29-0.81; p\u2009=\u20090.005) versus placebo in participants with active SPMS and 22% (HR, 0.78; 95% CI, 0.42-1.45; p\u2009=\u20090.437) in non-active SPMS. Siponimod reduced the risk of requiring a wheelchair in participants with SPMS versus participants receiving placebo, with a greater effect in those with active disease. Time to requiring a wheelchair is a highly relevant treatment goal and an important indicator of treatment effect in patients with SPMS.\n\nID: 42247418\nTitle: Fasciola hepatica excretory-secretory products attenuate demyelination and reduce neuroinflammation in the Cuprizone -induced multiple sclerosis model.\nAbstract: Multiple sclerosis (MS) is characterized by chronic neuroinflammation and progressive demyelination, with current therapies failing to adequately address both processes simultaneously. Helminth-derived excretory-secretory products (ESP) are immunomodulatory molecules that suppress host inflammation and are promising candidates for MS treatment. However, their capacity to promote remyelination remains poorly understood. This study investigated the effects of Fasciola hepatica ESP in the cuprizone-induced demyelination model. Male C57BL/6 mice were divided into four groups: control (CON), control\u2009+\u2009FES (CON\u2009+\u2009FES), cuprizone (CUP), and cuprizone\u2009+\u2009FES (CUP\u2009+\u2009FES). FES was administered intraperitoneally during the demyelination phase. Motor and cognitive functions were evaluated using open field, rotarod, wire grip, and shuttle box tests. Neuroinflammation was assessed by measuring TNF and IL-1\u03b2 levels, while myelin-related changes were evaluated by MBP and Olig2 expression (ELISA and qPCR) and Luxol Fast Blue staining. FES treatment significantly reduced pro-inflammatory cytokines, increased MBP and Olig2 levels, improved myelin integrity, and enhanced motor and cognitive performance compared to untreated cuprizone mice, though full recovery to control levels was not achieved. These findings demonstrate that FES attenuates neuroinflammation and is associated with partial improvements in myelin-related outcomes in the cuprizone model, supporting the therapeutic potential of helminth-derived molecules for MS.\n\nID: 42234285\nTitle: The Myelin-Derived Peptide NSDP1 Suppresses Neuroinflammation and Attenuates Demyelination in Chronic Cuprizone-Fed Mice via Modulation of cGAS-STING Signaling.\nAbstract: Multiple sclerosis (MS) is characterized by demyelination and neuroinflammation. In a cuprizone (CPZ)-induced demyelination mouse model, proteomic analysis revealed the significant downregulation of a myelin basic protein-derived peptide (sequence: DTGILDSIGRFFS), which we have designated as NSDP1 (nervous system-derived peptide 1). In vitro, NSDP1 suppressed LPS-induced microglial activation in BV2 cells, reducing reactive oxygen species (ROS) production, downregulating pro-inflammatory markers (iNOS, TNF-\u03b1, IL-1\u03b2), and upregulating the expression of anti-inflammatory marker Arg-1. In vivo, NSDP1 administration via intracerebroventricular injection significantly mitigated CPZ-induced weight loss and demyelination in the corpus callosum. NSDP1 attenuated CPZ-induced demyelination, restoring expression of myelin proteins (MAG, MOG), increasing oligodendrocyte precursor cell (OPC) density, improving myelin sheath ultrastructure, and enhancing axonal myelination efficiency. Furthermore, NSDP1 attenuated CPZ-induced reactive gliosis, reducing both microglial activation and astrocytic reactivity in the corpus callosum. RNA sequencing revealed that NSDP1 modulated myelination-related pathways and correlated with improved locomotor recovery. Mechanistically, NSDP1 exerted its anti-inflammatory effects by inhibiting the cGAS-STING signaling pathway, as shown by reduced cGAS and STING expression in LPS-stimulated BV2 cells. The effects of NSDP1 on ROS and pro-inflammatory cytokine release were reversed by the STING activator DMX and mimicked by the STING inhibitor SN-011. Collectively, these findings identify NSDP1 as a downregulated myelin-derived peptide with potent therapeutic potential, which attenuates demyelination and suppresses neuroinflammation in demyelinating diseases by inhibiting the cGAS-STING pathway.\n\nID: 42220502\nTitle: Case Report: Marburg variant of multiple sclerosis and review of its complicated treatment.\nAbstract: Marburg variant of multiple sclerosis (MS) is a rare, fulminant demyelinating disorder characterized by rapid neurological decline and notable lack of established standardized treatment guidelines. We describe a 46-year-old woman presenting with progressive cognitive and behavioral changes and multifocal CNS lesions initially refractory to corticosteroids, plasmapheresis (PLEX), and intravenous immunoglobulin (IVIg). Brain biopsy confirmed aggressive MS-spectrum demyelination. Escalation to high-dose cyclophosphamide resulted in radiologic stabilization but was limited by severe, refractory cytopenia. Given persistent disease activity and intolerance to infusion-based therapy, transition from ocrelizumab to subcutaneous ofatumumab was planned as a pragmatic maintenance strategy; however, treatment initiation was delayed. The patient subsequently experienced rapid clinical deterioration marked by recurrent aspiration events and functional decline, ultimately leading to death following transition to comfort-focused care. This case highlights the therapeutic challenges of Marburg MS, including treatment-limiting toxicity, logistical barriers to anti-CD20 therapy, and the critical importance of timely, individualized immunosuppressive strategies.\n\nID: 42207934\nTitle: Unveiling Remyelinating Properties of Roflumilast in CPZ-Induced Neuronal Demyelination in Mice.\nAbstract: Multiple sclerosis (MS) is a demyelinating disorder characterized by oligodendrocyte apoptosis, microglial activation at demyelination sites, with ROS production. These pathological processes are closely associated with phosphodiesterase-4 (PDE-4) activity. Roflumilast (ROFL), a selective PDE-4 inhibitor, has demonstrated neuroprotective effects in various central nervous system disorders. However, its specific role in MS pathogenesis remains to be fully elucidated. This study aims to investigate the effects of ROFL on oligodendrocyte maturation, microglial polarization and the impact on protein kinase A/cAMP-response element binding protein pathway. An MS model was induced in mice via dietary administration of cuprizone (CPZ) for 7 days, starting with 0.7% (w/w), followed by 0.2% for 5 weeks. Beginning in week 5, mice received ROFL (5\u2009mg/kg/day, p.o) for 2 weeks. ROFL improved the motor abnormalities in the rotarod and open field tests. Together, ROFL downregulated the PDE4/cAMP-dependent pathway, exerting anti-inflammatory effects by suppressing NF-\u03baB and TNF-\u03b1. Additionally, microglial polarization shifted toward the anti-inflammatory M2 phenotype, with CD163 increment, in contrast to the pro-inflammatory M1 marker CD83. Furthermore, ROFL's antioxidant capacity was evidenced by reduced malondialdehyde levels, replenishment of glutathione levels, and reduced phosphorylation of ERK1/2. Oligodendrocyte differentiation and maturation were enhanced, as indicated by elevated levels of proteolipid protein, myelin-associated glycoprotein, CNPase, and myelin basic protein. Remyelination was confirmed through Luxol fast blue staining, accompanied by reduced apoptotic marker, caspase-3, in oligodendrocytes. Collectively, these findings suggest that ROFL exerts neuroprotective effects and highlight the therapeutic potential of PDE-4 inhibition as a strategy for MS treatment.\n\nID: 42196494\nTitle: Spatiotemporal APLNR Expression Dynamics During Oligodendroglial Remodeling of the Corpus Callosum in the Cuprizone Model.\nAbstract: Demyelinating disorders such as multiple sclerosis are characterized by oligodendrocyte loss and insufficient remyelination. The cuprizone model provides a well-established experimental system for studying these processes. The apelinergic system, including the apelin receptor (APLNR), has been implicated in neuroprotection and central nervous system homeostasis. However, its role in white matter demyelination and repair remains incompletely understood. This study aimed to characterize the spatial and temporal dynamics of APLNR expression in relation to oligodendrocyte lineage cells in the corpus callosum (CC) during demyelination and remyelination. Demyelination was induced in 8-week-old C57BL/6 mice by 0.2% cuprizone supplementation in their drinking water for 5 weeks, followed by 5 weeks remyelination phase after toxin withdrawal. Histological assessment using Luxol Fast Blue/Cresyl violet staining was performed to evaluate structural changes in the CC. Immunohistochemistry and confocal microscopy were used to analyze APLNR expression, GST-\u03c0+ cells, and NG2+ cells, including their spatial distribution and co-localization. Quantitative analyses and correlation tests were conducted to assess relationships between cellular markers and CC area. Demyelination resulted in significant reduction in CC area and a marked decrease in GST-\u03c0+ cells, accompanied by a robust increase in NG2+ cells, while remyelination led to partial structural and cellular recovery. APLNR expression increased progressively from control to demyelination and further during remyelination, exhibiting pronounced regional heterogeneity with higher levels in lateral CC regions. Confocal analysis demonstrated increasing co-localization of APLNR with NG2+ cells, particularly during remyelination. Correlation analyses identified GST-\u03c0+ cell density as the strongest predictor of CC area, whereas APLNR showed phase-dependent associations, including a positive correlation with GST-\u03c0+ cells during remyelination and a negative relationship with NG2+ cells during demyelination. APLNR expression is dynamically regulated during cuprizone-induced demyelination and remyelination and is closely associated with oligodendrocyte lineage cell responses. Its increased expression and enhanced co-localization with NG2+ cells during remyelination suggest a potential role in endogenous repair processes. However, as the findings are based on descriptive analyses, further functional studies are required to determine the mechanistic contribution of APLNR signaling and its potential as a therapeutic target in demyelinating diseases.\n\nID: 42174808\nTitle: Environmental Personal Exposure Clusters to Investigate Multiple Sclerosis and Amyotrophic Lateral Sclerosis Progression.\nAbstract: Reliable prognosis in Multiple Sclerosis (MS) and Amyotrophic Lateral Sclerosis (ALS) is hampered by data scarcity and variability. Beyond clinical variables, evidence suggests that environmental data can help capture disease trajectories. We investigated whether personal environmental measures can be organized into stable patterns that inform prognosis. In a multicenter cohort, 293 patients with MS or ALS were equipped with Atmotube air-quality sensors. We normalized volatile organic compound (VOC) time series and computed Dynamic Time Warping distances to capture temporal similarity. Hierarchical clustering yielded five daily exposure clusters, which were profiled using Atmotube variables (season, day type, humidity, temperature) and patient self-reports (work status, time outdoors), and evaluated by day-level differences between personal and fixed-station variables. These clusters can support interpolation of missing wearable intervals and generation of context-aware exposure estimates, thereby strengthening environmental inputs for prognostic modeling in MS and ALS.\n\nID: 41986183\nTitle: Non-infectious environmental risk factors of multiple sclerosis: Mechanisms and intervention windows for prevention.\nAbstract: The trajectory of multiple sclerosis (MS) is shaped by complex interactions between genetic susceptibility and environmental factors. This review examines modifiable non-infectious determinants across the life course and proposes integrated prevention strategies. Key factors include vitamin D deficiency, low UV exposure, smoking, adolescent obesity, air pollution, and chemical environmental exposures. Mendelian randomization studies support the causality of several determinants, particularly low vitamin D and high BMI. Adolescence emerges as a critical susceptibility window where the maturing immune system is uniquely sensitive to metabolic and environmental triggers. Among validated interventions, vitamin D supplementation stands out for its ability to reduce disease activity in early MS. Effective prevention requires both individual actions and structural public health policies, such as air quality regulations and urban \"walkability\". Future efforts should prioritize multimodal strategies targeting high-risk youths through the educational system (physical activity, weight management, and smoking prevention). These holistic approaches offer broad-spectrum benefits, reducing the burden of MS while preventing comorbidities, including cardiovascular, metabolic but also cancer.\n\nID: 41824926\nTitle: Occupational Exposure to Industrial Dust and Rates of Multiple Sclerosis.\nAbstract: Exposure to lung irritants such as smoking and organic solvents has been associated with increased risk of multiple sclerosis (MS), particularly among genetically susceptible individuals. The aim of this study was to investigate the association between occupational exposure to industrial dust and MS and to assess potential interactions with smoking and HLA-DRB1*15:01. We conducted a Swedish population-based case-control study. Patients with incident MS age 16-70 years were consecutively identified by neurologists at 40 clinics (2005-2015). Eligibility criteria for participants were age 16-70 years, residence in Sweden, and a neurologist-confirmed diagnosis of MS according to the McDonald criteria. Controls without MS were randomly sampled from the national population register using density sampling and frequency-matched to cases on age, sex, and residential area. Occupational dust exposure was assessed using questionnaire data. Logistic regression was used to estimate odds ratios (ORs) and 95% CIs. Additive interactions between dust exposure and smoking and between dust exposure and HLA-DRB1*15:01 were assessed by calculating the attributable proportion (AP) due to interaction. An AP >0 is considered evidence of interaction. The analytic sample included 2,070 participants and 2,899 controls. The mean age at index was 34.4 years for participants and 35.4 years for controls. Women comprised 72.5% of participants and 75.1% of controls. Industrial dust exposure was associated with increased rate of MS (OR 1.30, 95% CI 1.05-1.63), with a dose-response relationship with duration (OR per 1-year exposure 1.03, 95% CI 1.00-1.06). Evidence of additive interactions was observed between dust exposure and smoking (AP 0.32, 95% CI 0.03-0.62) and between dust exposure and HLA-DRB1*15:01 (AP 0.25, 95% CI 0.002-0.52). Participants who smoked, were exposed to dust, and carried the HLA-DRB1*15:01 allele had an 11-fold increased rate of MS (OR 11.1, 95% CI 5.7-21.9), compared with those without any of these risk factors. Occupational dust exposure was associated with increased rate of MS, particularly in combination with smoking and HLA-DRB1*15:01, suggesting joint effects of occupational, environmental, and genetic risk factors. The reliance on self-reported occupational histories and potential residual confounding are important limitations. Further studies are warranted to clarify underlying mechanisms and to inform preventive strategies.\n\nID: 41812343\nTitle: Integrated determinants of multiple sclerosis susceptibility: Genetics, environment, infection and the microbiota.\nAbstract: Multiple sclerosis (MS) arises from the convergence of polygenic immune susceptibility, environmental exposures, and infectious determinants, none of which alone is sufficient for disease expression. More than 200 genetic variants contribute to MS risk, with the HLA-DRB115:01 haplotype providing the strongest effect within a broader network of immune-regulatory loci. Functional genomic evidence shows that these variants primarily influence antigen presentation and lymphocyte activation, creating an immune landscape that can be further shaped by external factors. This review integrates epidemiological, genomic, and mechanistic data to outline the main determinants of MS susceptibility. Epstein-Barr virus infection emerges as the dominant infectious driver, with seroconversion preceding early neuroaxonal injury and clinical onset. In contrast, cytomegalovirus infection appears protective, likely through immune imprinting that counterbalances EBV-driven B-cell and T-cell activation. Environmental factors including cigarette smoking, adolescent obesity, vitamin D deficiency, circadian disruption, and gut microbiota dysbiosis further modify susceptibility by promoting proinflammatory immune programs and reducing regulatory stability. Many of these exposures interact synergistically with HLA-DRB115:01, amplifying risk beyond additive expectations. These determinants influence shared immunological pathways regulating antigen presentation, lymphocyte differentiation, and immune tolerance. Clarifying these biological interfaces highlights actionable domains including smoking avoidance, metabolic health optimization, vitamin D sufficiency, viral prevention strategies, circadian alignment, and microbiome-targeted interventions that may inform risk-reduction and early identification efforts.\n\nID: 41770337\nTitle: Ozone pollution as a possible trigger for multiple sclerosis in young people: the PEDIGREE study.\nAbstract: Air pollution is linked to an increased risk of multiple sclerosis (MS) in adults. To investigate the link between air pollutant exposure and pediatric MS (pedMS) in an Italian cohort. PEDIGREE (Pediatric Italian Genetic and Environment Exposure) is a multicenter case-control study investigating genetic and environmental factors in MS before the age of 18. Information on environmental and perinatal exposures was collected through the PEQ-IT questionnaire. Air pollution data during the first, second, and third years prior to MS onset (PM2.5, PM10, O3, NO2, SO2, and CO levels) were obtained from the European Monitoring and Evaluation Program database. Data were available for 113 pedMS cases and 117 controls. We found statistically significant associations between pedMS and higher exposure to ozone (O3) in the first (OR\u2009=\u20091.11; 95% CI 1.03-1.19; p\u2009=\u20090.007), second (OR\u2009=\u20091.10; 95% CI 1.02-1.18; p\u2009=\u20090.012), and third (OR\u2009=\u20091.09; 95% CI 1.01-1.17; p\u2009=\u20090.025) year before MS onset, even after adjusting for gender, age at onset, sun exposure, parental smoking habit, and socioeconomic background. A one-unit increase in O3 exposure was associated with a roughly 10% increase in pedMS risk. O3 may play a significant role in the development of MS by promoting inflammation and oxidative stress.\n\nID: 41664350\nTitle: Air Pollution and the Risk and Progression of Multiple Sclerosis: A Systematic Review and Meta-Analysis.\nAbstract: Air pollution has been linked to several neurological conditions, including stroke and neurodegenerative diseases. Evidence regarding its association with multiple sclerosis (MS) remains conflicting, limited by small sample sizes. PubMed, Embase, Scopus, and Cochrane controlled register of trials (CENTRAL) were searched on September 9, 2025 without any language or time restrictions. The inclusion criteria were observational studies that evaluated the association between exposure to air pollutants and MS development or severity. Hazard ratios (HRs) with 95% confidence intervals (CIs) were pooled as effect estimates using the fixed or random effects model. Exposures included PM2.5, PM10, nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone (O3). Outcomes were MS risk and severity, including relapses, disability progression measured with the Expanded Disability Status Scale (EDSS), and contrast-enhancing lesions (CELs) development. Twenty-two studies comprising 16,585,206 participants were included. Long-term exposure to PM2.5 (HR\u2009=\u20091.21; 95% CI: 1.07-1.38), PM10 (HR\u2009=\u20091.20; 95% CI: 1.02-1.42), and CO (HR\u2009=\u20093.85; 95% CI: 1.34-11.08) were associated with increased MS risk. Short-term exposure to PM2.5 (HR\u2009=\u20091.20; 95% CI: 1.01-1.43), PM10 (HR\u2009=\u20091.20; 95% CI: 1.01-1.45), NO2 (HR\u2009=\u20091.13; 95% CI: 1.02-1.25), and O3 (HR\u2009=\u20091.15; 95% CI: 1.04-1.27) were associated with relapses. Short-term exposure to PM2.5 (HR\u2009=\u20092.20; 95% CI: 1.05-4.60) and PM10 (HR\u2009=\u20091.02; 95% CI: 1.01-1.03) were linked to CELs, while PM10 (HR\u2009=\u20091.31; 95% CI: 1.04-1.65) was associated with disability progression. Long-term air pollution exposure was associated with higher MS risk, and short-term exposure with greater disease severity. Reducing air pollution may be a key strategy to protect brain health in MS.\n\nID: 41616738\nTitle: The association of environmental exposure with multiple sclerosis severity score: A study based on sequential data modeling.\nAbstract: Introduction Multiple Sclerosis (MS) is a chronic neuroinflammatory disease influenced by clinical, demographic, and environmental factors. Predicting MS progression is challenging due to the disease's heterogeneity. This study aimed to apply Artificial Intelligence (AI) methods to investigate the association between the MS Severity Score (MSSS), which is a measure that integrates disability level and disease duration, and patients' longitudinal clinical data and environmental exposures. Methods We integrated long-term clinical records from the Mondino MS Center (Pavia, Italy) with environmental data, including air pollution and weather conditions, based on patients' residential locations. To address missing data, we applied a hybrid imputation strategy combining exponentially weighted moving average and linear mixed-effect models. Automated Machine Learning (AutoML) was used for feature selection. We evaluated multiple Deep Learning (DL) architectures, including recurrent neural network, long short-term memory, and Gated Recurrent Unit (GRU), using varying historical window lengths to predict the MSSS class at the next follow-up. Results The final retrospective dataset comprised 4022 visits from 535 MS patients. AutoML identified both clinical and environmental variables as important features for prediction. Models incorporating environmental data performed comparably to or better than those using only clinical variables. The GRU model achieved the most stable performance, with an average Area Under the Curve of 0.814 when environmental data were included with four prior visits. Moreover, SHAP-based feature importance ranked environmental variables like PM10, PM2.5, nitrogen dioxide, precipitation, and humidity among the top predictors. Conclusion Incorporating environmental exposures into DL models can improve MSSS prediction, highlighting the value of diverse real-world data for MS monitoring. Prediction performance across different historical window lengths was comparable, suggesting that using data from two prior follow-ups (approximately one year of monitoring) may be sufficient to provide clinically meaningful predictions of MS progression.\n\nID: 41581287\nTitle: Multiple sclerosis and related disorders multiple sclerosis across Isfahan Province, Iran: Urban-rural disparities and no association with air quality measures.\nAbstract: Multiple sclerosis (MS) prevalence varies worldwide and appears to be rising in Iran. Environmental factors like air pollution have been hypothesized to contribute to MS risk. This study aimed to map MS prevalence across Isfahan Province and evaluate differences by sex and urban versus rural setting, as well as to assess any association between ambient air pollution and MS prevalence. Data from 11,456 provincially registered MS patients in 28 counties in Isfahan, Iran, were examined in this cross-sectional ecological study. Official population estimates were used to calculate the county-level MS point prevalence per 100,000 population in 2023, stratified by sex. Ratios of females to males were calculated. Annual average PM\u2082.\u2085 levels for each county were obtained from state sources for the same period. MS prevalence was compared between urban and rural counties, and correlation/regression analyses were used to test associations with pollutant levels. The prevalence of MS varied widely, ranging from 322.7 in Isfahan County to 15.4 per 100,000 in rural Jarghouyeh. Although there was no significant correlation between the sex disparity and overall prevalence, females were more affected in every county (F/M ratio: 2.0-9.0). Although PM\u2082.\u2085 levels in Isfahan were extremely high (annual mean=41 \u03bcg/m\u00b3, >8 times the WHO guideline of 5 \u03bcg/m\u00b3), we found no significant correlation between ambient pollutant concentrations and MS prevalence in the province.\n\nID: 41564465\nTitle: Exposure to tobacco smoke during pregnancy and the risk of multiple sclerosis in offspring: A systematic review and meta-analysis.\nAbstract: Smoking is a common factor that contributes to the development of Multiple sclerosis during embryogenesis. Several studies found a correlation between maternal or paternal smoking and the development of Multiple sclerosis in offspring. Given inconclusive findings from recent studies, we aim to conduct a systematic review and meta-analysis of the relation between parental tobacco smoking and the risk of Multiple sclerosis in offspring. We systematically conducted comprehensive search screening including (PubMed, Scopus, Web of Science, Embase, and Cochrane Library) until July 2025. This study aimed to assess the relation between exposure to tobacco smoke during pregnancy (maternal and paternal smoking) and the risk of Multiple sclerosis in offspring. Pooled estimates were calculated using a random-effects model. The PROSPERO registration is CRD420251117243. This study included nine studies involving 1,405,641 participants, including 5,452 Multiple sclerosis patients. We did not find a correlation between maternal smoking during and before pregnancy and risk of Multiple sclerosis in offspring (OR = 1.13, 95% CI [0.9, 1.43], P-value= 0.30, I2= 53.7%), (OR = 1.11, 95% CI [0.83, 1.48], P-value= 0.48, I2 = 0%) respectively. We found a statistically significant association between paternal smoking and the risk of Multiple sclerosis in offspring (OR 1.62, 95% CI [1.24; 2.11], P-value= 0.00036, I2= 0%). These findings highlight a complex relationship between parental smoking and offspring risk of MS. We observed no clear association for maternal smoking, whereas paternal smoking was associated with an increased risk in offspring. However, neither result is definitive, and further well-designed prospective studies are required to confirm these associations and clarify underlying mechanisms.\n\nID: 41411973\nTitle: Co-exposure to PFAS and hydroxylated PCBs is associated with increased odds of multiple sclerosis.\nAbstract: Persistent organic pollutants often co-occur in human exposure environments, yet their combined effects on disease risk remain poorly understood. This study examined associations between serum concentrations of 14 per- and polyfluorinated substances (PFAS) and three hydroxylated polychlorinated biphenyls (OH-PCBs) and the onset of multiple sclerosis (MS), utilizing data from the Swedish population-based Epidemiological Investigation of Multiple Sclerosis (EIMS) cohort, comprising 907 MS cases and 907 matched controls. We employed single-substance logistic regression and quantile g-computation to evaluate cumulative and individual compound associations. We considered linear and non-linear risk patterns while adjusting for lifestyle factors and MS-associated HLA alleles. Our analysis revealed non-linear associations for several individual compounds, particularly perfluorooctane sulfonic acid (PFOS), perfluorononanoic acid, 2,2',3,4',5,5',6-heptachloro-4-biphenylol (4-OH-CB187), and 2,2',4,4',5,5'-, Hexachloro-3-biphenylol (3-OH-CB153), with increased odds of MS. Interaction analyses further indicated that the association between PFOS and MS odds was modified by the presence of the HLA-B*44:02 allele, known for its protective effect on MS risk. Mixture modeling highlighted that combined exposures to PFAS and OH-PCBs significantly increased MS odds, even when associations for individual compounds were weak or absent. These findings emphasize the complexity of associations between environmental contaminants, lifestyle and genetic risk factors, and the odds of MS. They underscore the importance of addressing co-exposure in environmental health research and call for further studies to elucidate underlying biological mechanisms.\n\nID: 41310962\nTitle: Exposure to Occupational Inhalants and the Risk of Developing Rheumatoid Arthritis: A Systematic Review and Meta-Analysis.\nAbstract: Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by joint pain, swelling, and stiffness. Although smoking is a well-established risk factor for RA, the role of occupational inhalants in RA development is less well recognized. This study aimed to systematically review and synthesize existing evidence on the association between occupational inhalants and the risk of developing RA. We conducted a systematic review and meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, searching MEDLINE, Embase, and Web of Science from database inception to November 20, 2024. Eligible studies were cross-sectional, were case-control and cohort designs, were population-based, reported original data on occupational inhalant exposures and RA, measured exposures, included a comparison group, and used reliable RA ascertainment methods. Studies relying solely on self-reported RA or focusing on treatment, prognosis, sick leave, or death were excluded. Two reviewers independently conducted literature screening, data extraction, and risk-of-bias assessment using the Newcastle-Ottawa Scale. Random-effects meta-analyses with relative risk were performed for cohort and case-control studies, and heterogeneity was assessed using the I2 statistic. In total, 31 studies met inclusion criteria, and 25 were included in meta-analyses across 10 types of occupational inhalants. Significant associations with RA risk were observed for exposure to silica, asbestos, solvents, pesticides, fertilizers, animal dust, and engine exhaust (relative risks ranging from 1.25 to 1.49). Moderate-to-high heterogeneity was observed in seven meta-analyses. Occupational inhalants are associated with increased RA risk, underscoring the importance of workplace prevention strategies and further research into biologic mechanisms.\n\nID: 41200026\nTitle: Exposome, oxidative stress and inflammation in persons with multiple sclerosis: the EXPOSITION study protocol.\nAbstract: The exposome represents the totality of external and internal exposures an individual encounters throughout life and plays a critical role in developing many chronic diseases, including multiple sclerosis (MS). MS is a multifactorial disease influenced by both genetic and environmental factors. The EXPOSITION study (registered on www.clinicaltrials.gov, NCT06325358) aims to investigate the association between environmental exposures (external exposome) and biological markers of oxidative stress and inflammation (internal exposome) in people with MS. This cross-sectional study will involve 200 individuals with MS, assessed for lifestyle and occupational variables and biological markers, including circulating microRNAs, neurofilament light chains, pro- and anti-inflammatory cytokines, and gut/nasal microbiota composition. The study will use advanced statistical models, such as generalised linear models and multivariate analyses, to assess associations between external exposures and biological outcomes. By integrating both environmental and biological factors, this research aims to deepen our understanding of MS mechanisms, providing insights that could lead to targeted interventions, personalised therapies, and public health strategies to mitigate MS progression.\n\nID: 41147838\nTitle: Childhood and Adolescent Environmental Risk Factors for Multiple Sclerosis: A Systematic Review With Meta-Analysis.\nAbstract: We aimed to provide updated evidence from the current literature regarding pediatric environmental factors associated with the risk of developing multiple sclerosis (MS). Articles were searched in PubMed, SciVerse ScienceDirect, and Web of Science. We included all clinical studies assessing the occurrence of MS at any age in association with the exposure to any environmental risk factor during childhood or adolescence. The main outcome was the occurrence of MS. The quality assessment was performed with the critical appraisal checklist for case-control studies. Pooled unadjusted effect sizes (OR) were calculated and reported with a 95% CI from random-effects meta-analysis. The review included 87 studies conducted across 20 countries. The studies analyzed diverse environmental risk factors, including infections, vaccinations, tobacco exposure, body mass index, and other pediatric exposures. EBV infection showed a significant positive association with MS risk (ES\u2009=\u20092.38, 95% CI\u2009=\u20091.80-3.15). Breastfeeding showed limited protective associations, and various adverse social experiences like bullying and sexual abuse were linked to increased MS risk. Active smoking during childhood/adolescence and obesity during these periods were associated with higher MS risk, while normal body mass index was protective. Antibiotic and chemical exposures, as well as vitamin D deficiency, were linked to higher MS risk. The review highlighted substantial heterogeneity and identified publication bias in studies on infections and vaccinations. Environmental risk factors for MS are important during childhood and adolescence. The first 20\u2009years are a key window for prevention and should be seen as an opportunity.\n\nID: 41108957\nTitle: Perfluorooctanesulfonic acid (PFOS) exposure and multiple sclerosis: Evidence of association and mechanistic insights.\nAbstract: While perfluoroalkyl substances (PFASs) exposure has been associated with autoimmune diseases (ADs), the robustness of these associations remains uncertain due to potential confounding and reverse causation in observational studies. This study aims to explore the potential relationship and underlying mechanisms between PFASs exposure and ADs risk. We utilized Mendelian randomization (MR) and generalized summary-data-based MR (GSMR) to investigate potential associations between exposure to two major PFASs (perfluorooctanoic acid [PFOA] and perfluorooctanesulfonic acid [PFOS]) and the risk of ten ADs, using genetic data exclusively from European-ancestry populations. For significant associations, we subsequently conducted network toxicology analysis, applied machine learning algorithms to systematically screen and prioritize key genes, and assessed immune infiltration analysis to elucidate mechanisms. We then validated these findings through molecular docking and molecular dynamics simulations. MR and GSMR analyses demonstrated a significant association between PFOS exposure and an increased risk of multiple sclerosis (MS). Among 107 intersecting candidate genes, four genes (CASP3, STAT3, ESR1, and GSK3B) were identified as key target genes through machine learning. Molecular docking and molecular dynamics simulations further confirmed stable binding interactions between PFOS and these proteins. Additionally, immune infiltration analysis suggested these genes may contribute to immune microenvironment dysregulation in MS. Pathway analysis indicated that PFOS potentially influences MS pathogenesis through PPAR signaling and efferocytosis. Our integrated analysis reveals evidence supporting an association between PFOS and MS and uncovers underlying molecular mechanisms. These findings establish a foundation for further investigation into the role of environmental pollutants in autoimmune disorders.\n\nID: 41066815\nTitle: Mechanism analysis of rotenone toxic exposure inducing neurotoxicity through the MAPK/MMPs signaling pathway.\nAbstract: Rotenone can enter the animal body directly through the skin and stomach, leading to neurotoxic effects. In this study, a mouse model of rotenone exposure was established to investigate the pathological changes and underlying mechanisms of rotenone-induced neurotoxicity. Behavioral tests, molecular biology techniques, gut microbiota analysis, and short-chain fatty acid (SCFA) content measurements were employed. The results demonstrated that rotenone exposure significantly reduced body weight, impaired motor coordination, and resulted in the loss of dopaminergic neurons (TH+) in the substantia nigra. It also activated microglia (Iba-1+) and astrocytes (GFAP+), and promoted the expression of pro-inflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1) as well as oxidative stress markers (iNOS, COX2). Furthermore, rotenone disrupted blood-brain barrier (BBB) integrity, evidenced by degradation of tight junction (TJ) proteins and Evans blue leakage, via activation of the MAPK-MMPs pathway (upregulation of p-P38 and p-JNK). Additionally, rotenone disturbed the intestinal microenvironment, manifesting as inflammatory cell infiltration, reduced SCFA levels, and gut microbiota dysbiosis. Intervention with Wuzi Yanzong Pill (WYP) reversed the aforementioned pathological alterations. This study reveals for the first time that rotenone induces Parkinson's disease (PD)-like pathology by disrupting the gut-brain axis through the MAPK-MMPs pathway. Meanwhile, WYP exerts multi-target therapeutic effects by modulating the central-peripheral interaction network, offering novel insights into the pathogenesis and intervention strategies of PD.\n\nID: 40815455\nTitle: A narrative review of genetic and environmental factors and risk for multiple sclerosis. The design of the Italian multicentric PEDIGREE study.\nAbstract: MS is the result of an immune-mediated disorder triggered by environmental factors in subjects genetically predisposed. Pediatric MS (pedMS) offers a unique window to study environmental triggers, as\u00a0patients are close to the actual onset of the disease and have been exposed to fewer confounding\u00a0factors. PedMS is strongly associated to HLA-DRB1*15:01 and to non-MHC (Major Histocompatibility Complex) variants, with a higher burden compared to adults. HLA-A*02 allele seems to reduce MS risk. The role of rare variants is still under investigation. Several environmental causative factors have been identified: obesity, passive smoke, sun exposure, vitamin D, and others but the\u00a0strongest candidate is the Epstein-Barr virus, considered a prerequisite for MS development. In this paper we provide a summary of the results obtained so far in pediatric age. Some years ago, the Italian PEDIGREE study (PEDiatric\u00a0Italian\u00a0Genetic and enviRonmental\u00a0ExposurE) has been created to help clarify the role of genetic and environmental factors in pedMS, through a study of the genetic, epigenetic, metagenomic, transcriptomic, along with assessment of environmental factors (viral exposure, second-hand smoke and sun exposure, breastfeeding history, and other factors. A network of 29 Italian MS centers has been established, 154 pedMS patients (mean age 13.5\u00a0years) and matched controls have been recruited. For the genetic study, a cohort of 364 adult MS patients with onset\u2009<\u200918\u00a0years was included. The study is ongoing, the results of exposure to environmental risk factors and of genetic background will be available in the next future.\n\nID: 40779553\nTitle: Long-term effects of air pollution on the incidence and progression of multiple sclerosis: A population cohort study in Isfahan, Iran.\nAbstract: Multiple sclerosis (MS) is a neurodegenerative disorder of the central nervous system characterized by autoimmune inflammation. Recent research indicates that environmental factors, particularly air pollution, may significantly affect the risk of developing MS. This study investigates the association between PM2.5 levels, as a measure of air pollution, and the incidence of MS in Isfahan, Iran, a city with one of the highest reported MS prevalence rates in the country. A retrospective population-based cohort study was conducted using data from the National MS registry of Iran and Isfahan's air pollution monitoring department from 2011 to 2021. The incidence of MS across urban areas was calculated, and the relationship between PM2.5 levels and the incidence rate ratio (IRR) of MS was assessed using a Poisson generalized regression models. PM2.5 levels averaged 41.99 \u00b5g/m3 across the study period (first year: 59.21\u2009\u00b1\u200933.56; mid-study: 30.51\u2009\u00b1\u200911.77; final year: 37.71\u2009\u00b1\u200953.64), persistently exceeding safety standards. Three-year cumulative exposure showed significant association with higher MS incidence (IRR\u2009=\u20091.027, 95%CI\u2009=\u20091.022-1.031, p\u2009<\u20090.001) and correlated with disease progression in progressive MS cases. Long-term exposure to PM2.5 is associated with an increased incidence of MS and disease progression, emphasizing the critical need for improved air quality management strategies.\n\nID: 40744174\nTitle: Tragacanth gum-deep eutectic solvent-based eutectogels for dextromethorphan transdermal delivery and induced rheumatoid arthritis treatment in rat.\nAbstract: A novel eutectogel of gelling natural deep eutectic solvents was developed based on the bassorin (Ba) fraction of tragacanth gum (a biological macromolecule) for transdermal delivery of dextromethorphan (DXM) in rheumatoid arthritis. The optimal eutectic combination of 1:2 malic acid and choline chloride (ChCl) was incorporated with Ba and water. The concentration of Ba used for preparing eutectogels was 2 w/w%. The results indicated that eutectic mixture of ChCl and malic acid greatly enhanced the solubility of DXM by more than 1700 times (0.19\u00a0\u00b1\u00a00.04 vs 324.20\u00a0\u00b1\u00a02.68\u00a0mg/mL). Increasing the water content to 60 w/w% in eutectogels resulted in decreased tensile strength (2.73 vs. 0.61\u00a0kg/cm2) and a narrower linear viscoelastic region in rheometry tests. All eutectogels retained their gel-like consistency at temperatures up to 80\u00a0\u00b0C. In texture profile analysis, eutectogels with lower water content showed more resistance to deformation than bassorin gel due to the physical cross-linking of the gelator. Cohesion tests demonstrated remarkable capacity of eutectogels to preserve structural integrity and superior adhesiveness than hydrogel counterparts. Eutectogels with 20\u00a0% water content had higher permeability of DXM through rat skin. Skin flux of DXM was significantly enhanced by eutectogel containing 20 w/w% of water (332.7\u00a0mg/cm2h) compared to the Ba gel with no eutectogel (just water and Ba) (57.1\u00a0mg/cm2h). In the rats treated with eutectogels containing 20\u00a0% water and 10 w/w% DXM, paw swelling rate and reduction of TNF-\u03b1 levels were not statistically different with oral methotrexate. Furthermore, the histological structure of their knee joints appeared nearly normal.\n\nID: 40664781\nTitle: Environmental risk factors for multiple sclerosis: a comprehensive systematic review and meta-analysis.\nAbstract: Multiple sclerosis (MS) is a demyelinating disease of the central nervous system. Its etiology may involve both genetic and environmental factors, including vitamin D levels, body mass index, infections, and smoking. This is the first comprehensive systematic review with meta-analysis that synthesizes and explore the role of many environmental risk factors in the etiology of MS. A systematic search of MEDLINE, SciVerse ScienceDirect and Web of Science were conducted for any original peer-reviewed article that included adult subjects diagnosed with and without MS that were exposed to any environmental risk factor. We did not set any time restrictions. Data were extracted and the quality assessment was performed with the Critical Appraisal Checklist for Case Control Studies. All the information was synthesized qualitatively and quantitatively (meta-analysis). We used the random-effects model based on the binomial distribution to calculate the pooled effects sizes (ES) regarding the risk of developing MS according to each potential risk factor. One-hundred thirty-two publications met all the eligibility criteria and were included in the review. Overall, 109,626 people with MS and 16,724,390 controls from 38 countries were included in the review. A total of 42 environmental risk factors were investigated as potential risk factors for MS. Among the various statistically significant associations, the pooled ES revealed a direct association between serological evidence of contact with EBV (ES\u2009=\u20091.96, 95% CI\u2009=\u20091.53-2.51), herpes virus type 6 (HHV-6) (ES\u2009=\u20092.84, 95% CI\u2009=\u20092.08-3.89) and varicella-zoster virus (ES\u2009=\u20091.33, 95% CI\u2009=\u20091.08-1.63) and the occurrence of MS. Similarly, smoking was associated with a greater likelihood of having MS (ES\u2009=\u20091.43, 95% CI\u2009=\u20091.27-1.61). Vitamin D levels at any time were negatively associated with the proportion of cases of MS and had a moderate pooled ES (g\u2009=\u2009-\u00a00.48, 95% CI\u2009=\u2009-\u00a00.88-0.09). Adult BMI was not associated with MS. This review furnishes a broad and detailed overview of the potential environmental risk factors associated with MS. Our findings hold notable implications for public health policies, clinical practices, and the focus of future research.\n\nID: 40597904\nTitle: Spectral resolution and speech comprehension performance in noise in individuals with multiple sclerosis.\nAbstract: Although multiple sclerosis is a chronic, autoimmune neurological disease of unknown etiology, the effects of the disease on the central auditory system are still a subject of research. Our study aimed to examine the performance of individuals with multiple sclerosis in speech understanding in noise and spectral resolution ability, which is known to be one of the functions of the central auditory system. A comparison was made between 32 individuals with multiple sclerosis (37.25 \u00b1 9.25 years) and 31 healthy individuals (34.96 \u00b1 8.42 years) in terms of the spectral resolution ability measured using the spectral-temporally modulated ripple test and speech comprehension performance in noise evaluated using the Turkish version of the matrix sentence test. There was no significant difference between the spectral resolution abilities of the two groups. However, speech comprehension performance in noise was significantly poorer in individuals with multiple sclerosis. Multiple sclerosis affects speech comprehension performance in noise, which is one of the central auditory system functions. In the auditory system evaluation of multiple sclerosis patients, performing peripheral and central auditory system evaluations together will yield more realistic results on communication problems that individuals may encounter daily.\n\nID: 40338549\nTitle: Proximity to Golf Courses and Risk of Parkinson Disease.\nAbstract: The role of pesticide exposure from golf courses in Parkinson disease (PD) risk remains unclear. To assess whether proximity to golf courses is associated with increased PD risk and to use information on groundwater vulnerability and municipal well locations to investigate drinking water contamination as a potential route of exposure. This case-control study included patients with incident PD and matched controls from the Rochester Epidemiology Project from 1991 to 2015. Data were analyzed between June and August 2024. Distance to golf courses, living in water service areas with a golf course, living in water service areas in vulnerable groundwater regions, living in water service areas with shallow municipal wells, and living in water service areas with a municipal well on a golf course. Risk of incident PD. All models adjusted for age, sex, race and ethnicity, year of index, median household income, and urban or rural category. A total of 419 incident PD cases were identified (median [IQR] age, 73 [65-80] years; 257 male [61.3%]) with 5113 matched controls (median [IQR] age, 72 [65-79] years; 3043 male [59.5%]; 4504 White [88.1%]). After adjusting for patient demographics and neighborhood characteristics, living within 1 mile of a golf course was associated with 126% increased odds of developing PD compared with individuals living more than 6 miles away from a golf course (adjusted odds ratio [aOR], 2.26; 95% CI, 1.09-4.70). Individuals living within water service areas with a golf course had nearly double the odds of PD compared with individuals in water service areas without golf courses (aOR, 1.96; 95% CI, 1.20-3.23) and 49% greater odds compared with individuals with private wells (aOR, 1.49; 95% CI, 1.05-2.13). Additionally, individuals living in water service areas with a golf course in vulnerable groundwater regions had 82% greater odds of developing PD compared with those in nonvulnerable groundwater regions (aOR, 1.82; 95% CI, 1.09-3.03). In this population-based case-control study, the greatest risk of PD was found within 1 to 3 miles of a golf course and risk generally decreased with distance. Associations with the largest effect sizes were in water service areas with a golf course and in vulnerable ground water regions.\n\nID: 40140341\nTitle: Environmental factors and rheumatic diseases.\nAbstract: The pathogenesis and pathophysiology of rheumatic diseases is complex and relies on the interaction of different factors. The common view is that the pathological autoimmunity develops in genetically predisposed individuals upon exposure to an environmental trigger. This highlights the importance of recognizing and deconstructing the effects of environmental agents in rheumatic diseases. Several factors have been identified in the last decades, with detrimental or protective effects, impacting not only on disease onset, but also on its natural history. Cigarette smoking has been identified as one of the strongest environmental risk factors, being associated with disease development and severity for several rheumatic diseases, including rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and spondyloarthropathies. Moreover, other airborne pollutants, such as silica, solvents, asbestos and metals are recognized risk factors for rheumatic diseases. The effect of some other agents is however not straightforward, of which a remarkable example is alcohol consumption. Alcohol has been associated with both pro- and anti-inflammatory effects, exerting a variable effect on rheumatic diseases depending on quantity and frequency of consumption, as well as sex and ethnicity. Similarly, ultraviolet light exposure has been associated with a higher risk of SLE but lower risk of RA. The relationship between microbial exposure and autoimmunity is also complex: while some infectious agents increase the risk of rheumatic diseases, it is widely accepted that less exposure to microbial agents, particularly during immune system development, increases the risk of autoimmunity. Furthermore, in recent years the spotlight has switched to the human microbiome, as alterations in organ-specific microbiome composition are anticipated to be early participants in the onset of immune-mediated illnesses. The aim of this review is to highlight the most relevant environmental factors and their role in Rheumatology, with a specific focus on proposed pathophysiological effect and correlation with clinical outcomes.\n\nID: 40066863\nTitle: Exploring the impact of ambient air PM2.5 on multiple sclerosis: an experimental dive into neuroinflammation.\nAbstract: There is mounting evidence about the connection between particulate matter (PM) and neuroinflammation. This study aimed to evaluate the toxicological effects of PM2.5 associated with inflammatory factors in a mouse's multiple sclerosis (MS) model. Thirty C57BL/6 male mice were categorized into five groups: a group of healthy mice, a control cuprizone-induced MS group, and three MS-induced groups, intranasally exposed to three concentrations of ambient air PM2.5 (5, 10, and 20\u2009mg/mL) from Tehran in a phosphate-buffered saline (PBS) solution. All mice were investigated by motor function, molecular, and histopathological assays. Moreover, the chemical content of the collected PM2.5 was assessed and reported. The cumulative exposure doses were equal to 0.025, 0.05, and 0.1\u2009mg per gram of body weight of mice, which were approximately 3.52, 7.04, and 14.08 times higher than the human daily dose in Tehran. The PM2.5-exposed groups showed a high inflammatory response characterized by a significant increase in the mRNA expression of tumor necrosis alpha (TNF-\u03b1), NLRP3, and interleukin 18 (IL-18). In addition, the PM2.5-exposed groups exhibited a notably lower velocity level, total traveled distance (TD), and duration traveled in the central zone (DC) than the control group. The histopathological assays revealed significant pathological alterations and demyelination in the PM2.5-exposed groups compared to the control group. Identifying the risks and reducing the likelihood of exposure through preventive measures and regulations can result in financial savings and improve the quality of life for MS patients.\n\nID: 40016224\nTitle: Associations of PFAS and OH-PCBs with risk of multiple sclerosis onset and disability worsening.\nAbstract: Exposure to per- and polyfluorinated substances (PFAS) and hydroxylated polychlorinated biphenyls (OH-PCBs) is associated with adverse human health effects, including immunosuppression. It is unknown if these substances can affect the course of autoimmune diseases. This study was based on 907 individuals with multiple sclerosis (MS) and 907 matched controls, where the MS cases were followed longitudinally using the Swedish MS register. We demonstrate sex- and disease-specific differences in serum PFAS concentrations between individuals with MS and controls. Moreover, two OH-PCBs (4-OH-CB187 and 3-OH-CB153) are associated with an increased risk of developing multiple sclerosis, regardless of sex and immigration status. With a clinical follow-up time of up to 18 years, an increase in serum concentrations of perfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), and perfluorodecanoic acid (PFDA) decreases the risk of confirmed disability worsening in both sexes, as well as perfluoroheptanesulfonic acid (PFHpS) and perfluorononanoic acid (PFNA), only in males with MS. These results show previously unknown associations between OH-PCBs and the risk of developing MS, as well as the inverse associations between PFAS exposure and the risk of disability worsening in MS.\n\nID: 40015115\nTitle: Environmental risk factors of late-onset multiple sclerosis: A population-based case-control study.\nAbstract: Late-onset multiple sclerosis (LOMS) was increasingly reported over the past two decades. Understanding the risk factors associated with LOMS can help improve early diagnosis, prevention strategies, and patients' quality of life. This study aimed to assess various environmental risk factors in the patients with late-onset disease. This study utilized a population-based case-control study design. Primary data on verified LOMS cases were received from Iran's national MS registry, with additional information gained via telephone interviews. The potential risk factors for LOMS were examined using a questionnaire modified from global case-control studies. Age and sex-matched healthy controls were selected using face-to-face interviews. The collected data were analyzed using matched logistic regression in Stata software version 14, reporting adjusted odds ratios (OR), and 95\u00a0% confidence intervals, with a significance level set at p\u00a0<\u00a00.05. This study examined 82 LOMS cases and 207 matched controls. The mean age of cases and controls was 61\u00a0years. The findings revealed that moderate and high sunlight exposure during adolescence were related with 0.33 (95\u00a0% CI: 0.18-0.58) and 0.15 (95\u00a0% CI: 0.04-0.46) times decreased risks of developing LOMS, respectively. Similarly, compared to those with low sunlight exposure, participants with high and moderate sunlight exposure during adulthood had a lower chance of developing MS disease (OR = 0.35, 95\u00a0% CI: 0.18-0.69) and (OR = 0.40 95\u00a0% CI: 0.18-0.85) receptively. Moreover, age at first menstruation (p\u00a0=\u00a00.45), age at first delivery (p\u00a0=\u00a00.49), abortion history (p\u00a0=\u00a00.79), and oral contraceptive consumption (p\u00a0=\u00a00.18) did not significantly differ among the groups (all p\u00a0>\u00a00.05). The odds of developing LOMS were 2.47 (95\u00a0% CI: 1.05-5.81) times higher for 10 to 90\u00a0min of heavy physical activity per week and 2.39 (95\u00a0% CI: 1.08-5.27) times higher for over 90\u00a0min. Various emotional stress, including death of a loved one (OR\u00a0=\u00a02.19, 95\u00a0% CI: 1.07-4.48), family disruption (OR\u00a0=\u00a02.93 95\u00a0% CI: 1.62-1.02), homelessness (OR\u00a0=\u00a09.1 95\u00a0% CI: 1.4-57.5), employment dismissal (OR\u00a0=\u00a04.0, 95\u00a0% CI: 1.31-12.1), and unemployment (OR\u00a0=\u00a03.1, 95\u00a0% CI: 1.25-7.62), were significantly associated with an increased risk of developing LOMS. Depression (OR\u00a0=\u00a05.5, 95\u00a0% CI: 2.7-10.9), measles (OR\u00a0=\u00a02.63, 95\u00a0% CI: 1.4-4.8), and a family history of MS (OR\u00a0=\u00a04.7, 95\u00a0% CI: 1.4-15.6) were also associated with higher risk of LOMS development. Sunlight exposure was shown to have a strong protective impact against LOMS. Furthermore, intensive physical activity, psychological stresses such as family upheavals, medical illnesses such as depression, and a positive family history of MS may all be associated with an increased risk of LOMS. These findings emphasized the importance of preventive measures for older individuals affected by the disease.\n\nID: 42029353\nTitle: Dental-amalgam exposure and the risk and progression of multiple sclerosis.\nAbstract: Concerns about the neurotoxic potential of dental amalgam in multiple sclerosis (MS) persists but its impact on disease risk and progression remains unclear. We used data from a Swedish population-based case-control study (2386 cases, 4849 controls) to investigate the association between dental amalgam exposure and MS risk. Odds ratios (ORs) with 95% confidence intervals (CIs) were estimated by using logistic regression and interaction with smoking was evaluated. Relapsing-onset MS cases born between 1965 and 1985 (n\u2009=\u20091191) were followed longitudinally by using clinical data from the Swedish MS registry. The time to confirmed disability worsening (CDW) and Expanded Disability Status Scale (EDSS) 3 and 4 were assessed by using Cox regression; EDSS trajectories were analysed by using linear mixed-effects models. Amalgam exposure was associated with increased MS risk in a dose-dependent manner (OR for trend 1.14, 95% CI 1.08-1.20). A significant interaction with smoking was observed (attributable proportion due to interaction 0.25, 95% CI 0.10-0.40). In the longitudinal cohort, those with at least six fillings had increased risk of CDW [hazard ratio (HR) 1.35, 95% CI 1.07-1.71] and progression to EDSS 3 (HR 1.48, 95% CI 1.07-2.05) and EDSS 4 (1.68, 95% CI 1.01-2.83). Associations were stronger among current smokers, those diagnosed after age 40\u00a0years, and individuals on low-efficacy therapies. The EDSS trajectories also showed faster progression in the high-exposure group (P\u2009=\u2009.044). Dental amalgam exposure may be associated with both increased risk of MS and faster disability progression. Findings support a potential synergistic effect with smoking and raise the hypothesis that mercury may contribute to MS-related neurodegeneration.\n\nID: 40004969\nTitle: Endogenous Ketone Bodies Are Associated with Metabolic Vulnerability and Disability in Multiple Sclerosis.\nAbstract: Purpose: Ketone bodies could be useful biomarkers in multiple sclerosis (MS) because the pathophysiological processes underlying MS disease progression induce metabolic stress. The purpose was to assess the relationships of ketone bodies with biomarkers of metabolic, inflammatory, and oxidative stress in MS. Methods: Blood samples and neurological assessments were obtained from 153 healthy controls (HC), 187 relapsing-remitting (RRMS), and 91 progressive MS (PMS) patients. AcAc, BHB, and acetone were measured using proton nuclear magnetic resonance spectroscopy. Indices of inflammatory vulnerability (IVX), metabolic malnutrition (MMX), and metabolic vulnerability (MVX) were computed from the NMR profiles. Cholesterol, apolipoprotein, lipid peroxidation, and antioxidant profiles were obtained. Regression analysis adjusted for age, sex, body mass index, and HC, RRMS, or PMS disease status. Results: AcAc and BHB levels were greater in MS compared to HC. BHB and ketone bodies were positively associated with disability on the MS Severity Scale and ambulation time. BHB was positively associated with IVX, MMX, and MVX. AcAc was positively associated with MMX and negatively associated with IVX and MVX. Total ketone body concentration was positively associated with MMX and MVX. BHB and AcAc levels were negatively associated with the amino acids alanine, valine, and leucine. Conclusions: Ketone bodies are associated with inflammatory vulnerability, metabolic vulnerability, and ambulatory disability measures in MS.\n\nID: 37772966\nTitle: Organic solvents and Multiple Sclerosis: the doubled risk dilemma.\nAbstract: Compensation for industrial disease in the UK may be obtained in two ways. A State scheme includes a list of accepted associations between occupations and diseases with evidence of a causative association. Epidemiological evidence of a doubled risk in the occupation concerned is usually required. This takes no account of variation of exposures within occupations, excluding many occupations where risk is less than doubled. In such cases, compensation for a perceived industrial illness may be obtained in Civil Courts, where excessive exposures can be considered. To show that in the Civil Courts evidence of excessive exposure may lead to compensation for diseases which are not yet compensable as Industrial Injuries in the UK and to draw attention to the association of multiple sclerosis (MS) with solvent exposure. We report the case of an industrial spray painter, who claimed his MS had been caused by high-level exposure to organic solvents, and our examination of the epidemiological evidence submitted. The painter received compensation by an out-of-court settlement, despite the overall epidemiological risk in relation to solvent exposure having been shown to be less than doubled. The evidence hinged on individual risk in relation to high exposure, genetic susceptibility and demonstration of a plausible mechanism. High organic solvent exposure may lead to the development of MS. Those giving evidence in Court need to be able to discuss the epidemiological and toxicological issues in relation to exposure in the individual case.\n\nID: 37207441\nTitle: A metabolome-wide Mendelian randomization study prioritizes potential causal circulating metabolites for multiple sclerosis.\nAbstract: To prioritize circulating metabolites that likely play causal roles in the pathogenesis of multiple sclerosis (MS). Two-sample Mendelian randomization analysis was performed to estimate the causal effects of 571 circulating metabolites on the risk of MS. Genetic instruments for circulating metabolites were obtained from three previous genome-wide association studies (GWAS) of the blood metabolome (N\u00a0=\u00a07824; 24,925; and 115,078; respectively), while genetic associations with MS were from a large GWAS by the International Multiple Sclerosis Genetics Consortium (14,802 cases and 26,703 control). The primary analysis was performed with the multiplicative random-effect inverse variance-weighted method, while multiple sensitivity analyses were conducted with the weighted median, weighted mode, MR-Egger, and MR-PRESSO. A total of 29 metabolites had suggestive evidence of causal associations with MS. Genetically instrumented levels of serine (OR\u00a0=\u00a01.56, 95% CI\u00a0=\u00a01.25-1.95), lysine (OR\u00a0=\u00a01.18, 95% CI\u00a0=\u00a01.01-1.38), acetone (OR\u00a0=\u00a02.45, 95% CI\u00a0=\u00a01.02-5.90), and acetoacetate (OR\u00a0=\u00a02.47, 95% CI\u00a0=\u00a01.14-5.34) were associated with a higher MS risk. Total cholesterol and phospholipids in large very-low-density lipoprotein were associated with a lower MS risk (OR\u00a0=\u00a00.83, 95% CI\u00a0=\u00a00.69-1.00; OR\u00a0=\u00a00.80, 95% CI\u00a0=\u00a00.68-0.95), but risk-increasing associations (OR\u00a0=\u00a01.20, 95% CI\u00a0=\u00a01.04-1.40; OR\u00a0=\u00a01.13, 95% CI\u00a0=\u00a01.00-1.28) were observed for the same two lipids in very large high-density lipoprotein. Our metabolome-wide Mendelian randomization study prioritized a list of circulating metabolites, such as serine, lysine, acetone, acetoacetate, and lipids, that likely have causal associations with MS.\n\nID: 37037643\nTitle: [Multiple sclerosis, work and job retention].\nAbstract: Becoming unfit for work or losing one's job because of multiple sclerosis is not inevitable. Many tools are available and occupational health professionals are now specifically mandated to support workers, whether or not they are employees, in maintaining their jobs, thanks in particular to the prevention of professional displacement unit, the recommendations of the French National Authority for Health and better coordination.\n\nID: 34081364\nTitle: Total Synthesis of Aetokthonotoxin, the Cyanobacterial Neurotoxin Causing Vacuolar Myelinopathy.\nAbstract: Aetokthonotoxin has recently been identified as the cyanobacterial neurotoxin causing Vacuolar Myelinopathy, a fatal neurologic disease, spreading through a trophic cascade and affecting birds of prey such as the bald eagle in the USA. Here, we describe the total synthesis of this specialized metabolite. The complex, highly brominated 1,2'-biindole could be synthesized via a Somei-type Michael reaction as key step. The optimised sequence yielded the natural product in five steps with an overall yield of 29\u2009%.\n\nID: 33176518\nTitle: A Qualitative Exploration of Occupational Adaptation in Caregivers of People with Multiple Sclerosis.\nAbstract: Due to the unpredictable and progressive nature of multiple sclerosis, the burden of care is placed on the primary caregivers. This study aimed to explore occupational adaptation strategies implemented by primary caregivers to adapt to occupational challenges of caregiving. Seventeen primary caregivers of people with MS were interviewed using purposive sampling techniques. Data were analyzed using content analysis method. Two main categories of strategies were determined: (a) Strategies to alleviate intrapersonal challenges of occupational adaptation; and (b) Strategies to alleviate environmental challenges of occupational adaptation. These included various skills and solutions that aided primary caregivers' adaptation toward occupational challenges. Based on the results of this study, occupational adaptation is a means of achieving mastery in alleviating occupational challenges to cope with adverse circumstances. The results of this study can be used to help therapists design appropriate caregiver-focused interventions, ultimately improving caregiver performance.\n\nID: 32880046\nTitle: Work-related exposure to organic solvents and the risk for multiple sclerosis-a systematic review.\nAbstract: Multiple sclerosis (MS) is a chronic progressive neurological disorder. Several environmental factors have been discussed as possible causing agents, e.g. organic solvents, whose impact on the disease is analysed in this review. Systematic search strategies were used to identify high-quality studies of workers exposed to organic solvents, published up to September 30, 2019, in databases, such as PubMed, Cochrane library and Scopus. The exposure was in most studies obtained by questionnaires, supplemented with telephone interviews. The diagnosis MS was mainly detemined following a thorough neurological examination. Finally, fourteen case-control studies and two cohort studies met the inclusion criteria and were included in the meta-analysis. Random effects models were used to pool the results of the studies. The odds ratios from the 14 case-control studies included in the meta-analysis ranged from 0.12-4.0. Five case-control studies and one cohort study showed a significant association between the development of multiple sclerosis and exposure to organic solvents. The results from the other nine case-control studies and from one of the two cohort studies did not reach statistical significance. The pooled data from the 14 case-control studies gave an OR of 1.44 (95% CI 1.03-1.99), which shows a moderately increased risk of developing MS after exposure to organic solvents. The final interpretation of the result is that organic solvents may be slightly associated with an increased risk to develop MS. In addition, other factors, e.g. genetic markers and smoking, may contribute to the development of the disease.\n\nID: 32728946\nTitle: An atlas on risk factors for multiple sclerosis: a Mendelian randomization study.\nAbstract: We conducted a systematic review and wide-angled Mendelian randomization (MR) study to examine the association between possible risk factors and multiple sclerosis (MS). We used MR analysis to assess the associations between 65 possible risk factors and MS using data from a genome-wide association study including 14 498 cases and 24 091 controls of European ancestry. For 18 exposures not suitable for MR analysis, we conducted a systematic review to obtain the latest meta-analyses evidence on their associations with MS. Childhood and adulthood body mass index were positively associated with MS, whereas physical activity and serum 25-hydroxyvitamin D were inversely associated with MS. There was evidence of possible associations of type 2 diabetes, waist circumference, body fat percentage, age of puberty and high-density lipoprotein cholesterol. Data of systematic review showed that exposure to organic solvents, Epstein Barr virus and cytomegalovirus virus infection, and diphtheria and tetanus vaccination were associated with MS risk. This study identified several modifiable risk factors for primary prevention of MS that should inform public health policy.\n\nID: 31841592\nTitle: Association Between Cigarette Smoking and Multiple Sclerosis: A Review.\nAbstract: Cigarette smoking is a common environmental exposure and addiction, which has severe health consequences. Smoking is a risk factor for multiple sclerosis (MS); also, smoking has been associated with disease activity and overall prognosis for patients with MS. Cigarette smoking is an irritative agent on the lungs, in which a proinflammatory cascade starts that culminates in autoimmunity. Inflammation may increase the risk of MS in some individuals, in a process driven by antigen cross-reactivity between lung antigens and myelin antigens. Genetics plays a central role in the individual predisposition to mounting an autoimmune reaction. Also, free radicals, cyanates, and carbon monoxide in cigarette smoke may be directly toxic to neurons. Patients with MS who smoke have higher rates of disease activity, faster rates of brain atrophy, and a greater disability burden. Some of the outcomes of smoking were found to be reversible, which makes counseling key. The pathways involved in cigarette smoking should be further analyzed to understand the mechanisms whereby smoking worsens MS prognosis. The proinflammatory and neurotoxic outcomes of cigarette smoking may be shared by other environmental exposures, such as pollution and organic solvents. From a global perspective, efforts should be made to diminish the prevalence of cigarette smoking in patients with MS.\n\nID: 31676154\nTitle: Organic solvent exposure as a risk factor for multiple sclerosis: An updated review.\nAbstract: Organic solvents exposure has for a long time been suspected as a risk factor for developing multiple sclerosis. The evidence, containing case reports, case-control studies and cohort studies has been contradictory. An early meta-analysis, however, pointed to a doubled risk for MS. Recent major case-control studies confirm this, but also have elucidated the risk pattern, being dependent on another risk factor, i.e. smoking.\n\nID: 31134532\nTitle: Altered Cerebrospinal Fluid Concentrations of Hydrophobic and Hydrophilic Compounds in Early Stages of Multiple Sclerosis-Metabolic Profile Analyses.\nAbstract: The lack of a single predictive or diagnostic test in multiple sclerosis (MS) remains a major obstacle in the patient's care. The aim of this study was to investigate metabolic profiles, especially lipids in cerebrospinal fluid (CSF) using 1H-NMR spectroscopy and metabolomics analysis to discriminate MS patient group from the control ones. In this study, 19 MS patients and 19 controls, without neurological problems, patients were enrolled. To obtain the CSF metabolic profiles, NMR spectroscopy was used. Hydrophilic and hydrophobic compounds were analyzed using univariate and multivariate supervised analysis orthogonal partial least square discriminant analysis (OPLS-DA). Targeted OPLS-DA analysis of 32 hydrophilic and 17 hydrophobic compounds obtained 9 hydrophilic metabolites and 8 lipid functional groups which had the highest contribution to patient's group separation. Lower concentrations of CSF hydrophilic and hydrophobic compounds were observed in MS patients as compared to control group. Acetone, choline, urea, 1,3-dimethylurate, creatinine, isoleucine, myo-inositol, leucine, and 3-OH butyrate; saturated and monounsaturated acyl groups of \u03c9-9, \u03c9-7, \u03c9-6, \u03c9-3, and fatty acid, triglycerides, 1,3-DG, 1-MG, and unassigned component signal at 3.33\u00a0ppm were the most important signal compounds in group separation. Analysis of metabolic profile of raw CSF and their lipid extract shows decreased levels of many compounds and led to the conclusion that MS patients could have a disturbance in many metabolic pathways perhaps leading to the decreased level of acetyl-CoA and/or inflammation. CSF metabolic profile analyses could be used as a fingerprint for early MS diagnosis.\n\nID: 30930422\nTitle: Dimethyl Fumarate Attenuates Oxaliplatin-Induced Peripheral Neuropathy without Affecting the Anti-tumor Activity of Oxaliplatin in Rodents.\nAbstract: Oxaliplatin has been used as a first choice for colorectal, gastric and pancreatic cancer, but it induces peripheral neuropathies. Dimethyl fumarate (DMF) is an oral drug for multiple sclerosis with neuroprotective effects on oxidative stress. Using both in vivo and in vitro models, we investigated the effects of DMF on oxaliplatin-induced peripheral neuropathy and other side effects, as well as on the anti-tumor activity of oxaliplatin. Repeated intraperitoneal injection of 4\u2009mg/kg oxaliplatin (twice per week for 4 weeks) caused mechanical allodynia (as revealed by the von Frey tests), cold hyperalgesia (as revealed by the acetone tests), and axonal degeneration in the sciatic nerve of rats. Co-administration of oral DMF (200\u2009mg/kg, five times per week for 4 weeks) relieved oxaliplatin-induced mechanical allodynia but not cold hyperalgesia, and ameliorated axonal degeneration. In addition, DMF did not exacerbate oxaliplatin-induced body weight loss or bone marrow suppression, such as reduction in red blood cells, white blood cells, neutrophils and lymphocytes. Furthermore, DMF did not inhibit the anti-tumor activity of oxaliplatin in any cultured cancer cell line (C26, mouse colon carcinoma; HCT116, human colon carcinoma; MKN45, human gastric adenocarcinoma; MIA PaCa-2, human pancreatic carcinoma) or C26-bearing mice. These results suggest that DMF prevents oxaliplatin-induced mechanical allodynia and axonal degeneration without affecting the anti-tumor activity of oxaliplatin. Therefore, DMF may be useful for managing oxaliplatin-induced chronic peripheral neuropathy.\n\nID: 30841532\nTitle: The Beneficial and Debilitating Effects of Environmental and Microbial Toxins, Drugs, Organic Solvents and Heavy Metals on the Onset and Progression of Multiple Sclerosis.\nAbstract: Multiple sclerosis (MS), a chronic inflammatory disease of the central nervous system is common amongst young adults, leading to major personal and socioeconomic burdens. However, it is still considered complex and challenging to understand and treat, in spite of the efforts made to explain its etiopathology. Despite the discovery of many genetic and environmental factors that might be related to its etiology, no clear answer was found about the causes of the illness and neither about the detailed mechanism of these environmental triggers that make individuals susceptible to MS. In this review, we will attempt to explore the major contributors to MS autoimmunity including genetic, epigenetic and ecological factors with a particular focus on toxins, chemicals or drugs that may trigger, modify or prevent MS disease.\n\nID: 30820880\nTitle: Assessing the Metabolomic Profile of Multiple Sclerosis Patients Treated with Interferon Beta 1a by 1H-NMR Spectroscopy.\nAbstract: Metabolomic research has emerged as a promising approach to identify potential biomarkers in multiple sclerosis (MS). The aim of the present study was to determine the effect of interferon beta (IFN \u00df) on the metabolome of MS patients to explore possible biomarkers of disease activity and therapeutic response. Twenty-one MS patients starting IFN \u00df therapy (Rebif\u00ae 44\u00a0\u03bcg; s.c. 3 times per week) were enrolled. Blood samples were obtained at baseline and after 6, 12, and 24\u00a0months of IFN \u00df treatment and were analyzed by high-resolution nuclear magnetic resonance spectroscopy. Changes in metabolites were analyzed. After IFN \u00df exposure,\u00a0patients\u00a0 were divided into responders and nonresponders according to the \"no evidence of disease activity\" (NEDA-3) definition (absence of relapses, disability progression, and magnetic resonance imaging activity), and samples obtained at baseline were analyzed to evaluate the presence of metabolic differences predictive of IFN \u00df response. The results of the investigation demonstrated differential distribution of baseline samples compared to those obtained during IFN \u00df exposure, particularly after 24\u00a0months of treatment (R2X\u2009=\u20090.812, R2Y\u2009=\u20090.797, Q2\u2009=\u20090.613, p\u2009=\u20090.003). In addition, differences in the baseline metabolome between responder and nonresponder patients with respect to lactate, acetone, 3-OH-butyrate, tryptophan, citrate, lysine, and glucose levels were found (R2X\u2009=\u20090.442, R2Y\u2009=\u20090.768, Q2\u2009=\u20090.532, p\u2009=\u20090.01). In conclusion, a metabolomic approach appears to be a promising, noninvasive tool that could potentially contribute to predicting the efficacy of MS therapies.\n\nID: 30463091\nTitle: Safranal Attenuates Excitotoxin-Induced Oxidative OLN-93 Cells Injury.\nAbstract: Researches have been shown that glutamic acid (GA) or quinolinic acid (QA) can play role in neuroinflammatory and demyelinating diseases including multiple sclerosis (MS), mainly via oligodendrocytes activation and extreme free radicals generation. Recent studies have demonstrated that safranal, an active constituent of Crocus sativus, has several pharmacological effects such as antioxidant, anti-inflammatory and neuroprotective properties. Since there is no data about the impact of safranal on MS, this study was designed to investigate the protective effect of safranal on OLN-93 oligodendrocytes injury induced by GA or QA. At first, the potential toxic effect of safranal on OLN-93 viability was evaluated. Also, the cells were pretreated with safranal (0.1, 1, 10, 50, 100 and 200\u2009\u03bcM) for 2\u2009h and then subjected to GA (16\u2009mM) or QA (8\u2009mM) toxicity for 24\u2009h, in which the same treatments were applied. The cell viability and parameters of redox status such as the levels of intracellular reactive oxygen species (ROS) and lipid peroxidation were measured. Safranal at concentration ranges of 1-800\u2009\u03bcM had no toxic effect on cell viability (p>0.05). Treatment with safranal significantly increased cell viability following GA or QA insults at concentrations higher than 1\u2009\u03bcM (p<0.01). The cytoprotective potential of safranal was also accompanied by decreased ROS accumulation (p<0.001) and malondialdehyde level (p<0.001) following GA or QA insults. The data suggests that safranal exhibits oligoprotection potential by means of inhibiting oxidative stress parameters.\n\nID: 30249932\nTitle: Improving the job-retention strategies in multiple sclerosis workers: the role of occupational physicians.\nAbstract: Several studies evaluated whether a person with multiple sclerosis is employed or not and investigated the main symptoms that hinder the job performance. However, despite occupational physicians are fundamental in managing disabled subjects, there is a serious lack of data regarding their role in improving employability of these workers. In this regard, we assessed occupational physicians' professional activity and training/updating needs in order to identify and develop management tools, operative procedures and training programs helpful to support and implement adequate job-retention strategies. Four hundred three Italian occupational physicians compiled a self-administered questionnaire to evaluate individual demographics, health surveillance system, fitness for work and training needs. Our findings confirmed the suitability to adopt environmental adjustments at workplace (particularly referring to the ergonomics of workstation, the typology of occupational risk factors and the working time) to accommodate individual's needs in order to improve working ability among multiple sclerosis workers. Moreover, training events discussing operational guidelines and standardized instruments and/or methodologies to adequately manage the disable workers should be fostered. Therefore, in this regard, occupational physicians could play a key role but they need more high-quality training especially concerning the different tools that are currently available to assess the work issues in multiple sclerosis patients.\n\nID: 30030330\nTitle: Low-dose onabotulinumtoxinA improves urinary symptoms in noncatheterizing patients with MS.\nAbstract: To evaluate the efficacy and safety of onabotulinumtoxinA 100 U in noncatheterizing patients with multiple sclerosis (MS) with urinary incontinence (UI) due to neurogenic detrusor overactivity (NDO). In this randomized, double-blind phase III study, patients received onabotulinumtoxinA 100 U (n = 66) or placebo (n = 78) as intradetrusor injections via cystoscopy. Assessments included changes from baseline in urinary symptoms, urodynamics, and Incontinence-Quality of Life (I-QOL) total score. Adverse events (AEs) were assessed, including initiation of clean intermittent catheterization (CIC) due to urinary retention. OnabotulinumtoxinA vs placebo significantly reduced UI at week 6 (-3.3 episodes/day vs -1.1 episodes/day, p < 0.001; primary endpoint). Significantly greater proportions of onabotulinumtoxinA-treated patients achieved 100% UI reduction (53.0% vs 10.3%, p < 0.001). Significant improvements in urodynamics (p < 0.01) were observed with onabotulinumtoxinA. Improvements in I-QOL score were significantly greater with onabotulinumtoxinA (40.4 vs 9.9, p < 0.001) and \u22483 times the minimally important difference (+11 points). The most common AE was urinary tract infection (25.8%). CIC rates were 15.2% for onabotulinumtoxinA and 2.6% for placebo. In noncatheterizing patients with MS, onabotulinumtoxinA 100 U significantly improved UI and quality of life with lower CIC rates than previously reported with onabotulinumtoxinA 200 U. NCT01600716. This study provides Class I evidence that compared with placebo, 100 U onabotulinumtoxinA intradetrusor injections significantly reduce UI and improve quality of life in noncatheterizing patients with MS and NDO.\n\nID: 29970406\nTitle: Organic solvents and MS susceptibility: Interaction with MS risk HLA genes.\nAbstract: We hypothesize that different sources of lung irritation may contribute to elicit an immune reaction in the lungs and subsequently lead to multiple sclerosis (MS) in people with a genetic susceptibility to the disease. We aimed to investigate the influence of exposure to organic solvents on MS risk, and a potential interaction between organic solvents and MS risk human leukocyte antigen (HLA) genes. Using a Swedish population-based case-control study (2,042 incident cases of MS and 2,947 controls), participants with different genotypes, smoking habits, and exposures to organic solvents were compared regarding occurrence of MS, by calculating odds ratios with 95% confidence intervals using logistic regression. A potential interaction between exposure to organic solvents and MS risk HLA genes was evaluated by calculating the attributable proportion due to interaction. Overall, exposure to organic solvents increased the risk of MS (odds ratio 1.5, 95% confidence interval 1.2-1.8, p = 0.0004). Among both ever and never smokers, an interaction between organic solvents, carriage of HLA-DRB1*15, and absence of HLA-A*02 was observed with regard to MS risk, similar to the previously reported gene-environment interaction involving the same MS risk HLA genes and smoke exposure. The mechanism linking both smoking and exposure to organic solvents to MS risk may involve lung inflammation with a proinflammatory profile. Their interaction with MS risk HLA genes argues for an action of these environmental factors on adaptive immunity, perhaps through activation of autoaggressive cells resident in the lungs subsequently attacking the CNS.\n\nID: 29735578\nTitle: Lifestyle and Environmental Factors in Multiple Sclerosis.\nAbstract: Lifestyle and environmental factors potently influence the risk of multiple sclerosis (MS), because genetic predisposition only explains a fraction of the risk increase. There is strong evidence for associations of Epstein-Barr virus (EBV) infection, smoking, sun exposure/vitamin D, and adolescent obesity to risk of MS. There is also circumstantial evidence on organic solvents and shift work, all associate with greater risk, although certain factors like nicotine, alcohol, and a high coffee consumption associate with a reduced risk. Certain factors, smoking, EBV infection, and obesity interact with human leukocyte antigen (HLA) risk genes, arguing for a pathogenic pathway involving adaptive immunity. There is a potential for prevention, in particular for people at greater risk such as relatives of individuals with MS. All of the described factors for MS may influence adaptive and/or innate immunity, as has been argued for MS risk gene variants.\n\nID: 28746356\nTitle: Metabolomic profiling of CSF in multiple sclerosis and neuromyelitis optica spectrum disorder by nuclear magnetic resonance.\nAbstract: Multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) are inflammatory diseases of the central nervous system. Although several studies have characterized the metabolome in the cerebrospinal fluid (CSF) from MS and NMOSD patients, comparative analyses between them and between the relapse and the remission of each disease have not been performed. Both univariate and multivariate analyses were used to compare 1H-NMR spectra of CSF from MS, NMOSD, and healthy controls (HCs). The statistical analysis showed alterations of eight metabolites that were dependent on the disease. Levels of 2-hydroxybutyrate, acetone, formate, and pyroglutamate were higher and levels of acetate and glucose were lower in both MS and NMOSD. Citrate was lower in MS patients, whereas lactate was higher in only NMOSD specifically. The shared feature of metabolic changes between MS and NMOSD may be related to altered energy metabolism and fatty acid biosynthesis in the brain. Another analysis to characterize relapse and remission status showed that isoleucine and valine were down-regulated in MS relapse compared to MS remission. The other metabolites identified in the disease comparison showed the same alterations regardless of disease activity. These findings would be helpful in understanding the biological background of these diseases, and distinguishing between MS and NMOSD, as well as determining the disease activity.\n\nID: 28618110\nTitle: Intravesical vanilloids for treating neurogenic lower urinary tract dysfunction in patients with multiple sclerosis: A systematic review and meta-analysis. A report from the Neuro-Urology Promotion Committee of the International Continence Society (ICS).\nAbstract: To systematically assess all available evidence on efficacy and safety of vanilloids for treating neurogenic lower urinary tract dysfunction (NLUTD) in patients with multiple sclerosis (MS). This systematic review and meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Studies were identified by electronic search of Cochrane register, Embase, Medline, Scopus, (last search January 8, 2016). After screening of 7848 abstracts, 4 randomized controlled trials (RCTs) and 3 prospective cohort studies were included. Pooled data from three RCTs evaluating intravesical capsaicin showed the standardized mean difference to be -2.16 (95% confidence interval [CI] -2.87 to -1.45) in incontinence episodes per 24\u2009h and -0.54 (95%CI -1.03 to -0.05) in voids per 24\u2009h. There was no statistically significant effect on maximum cystometric capacity and maximum storage detrusor pressure. Overall, adverse events were reported by >50% of the patients, most commonly were pelvic pain, facial flush, worsening of incontinence, autonomic dysreflexia, urinary tract infection and haematuria. Risk of bias and confounding was relevant in both RCTs and non-RCTs. Preliminary data suggest that intravesical vanilloids might be effective for treating NLUTD in patients with MS. However, the safety profile seems unfavorable, the overall quality of evidence is low and no licensed substance is currently available warranting well-designed, adequately sampled and properly powered RCTs.\n\nID: 28208701\nTitle: Excitotoxins, Mitochondrial and Redox Disturbances in Multiple Sclerosis.\nAbstract: Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS). There is increasing evidence that MS is not only characterized by immune mediated inflammatory reactions, but also by neurodegenerative processes. There is cumulating evidence that neurodegenerative processes, for example mitochondrial dysfunction, oxidative stress, and glutamate (Glu) excitotoxicity, seem to play an important role in the pathogenesis of MS. The alteration of mitochondrial homeostasis leads to the formation of excitotoxins and redox disturbances. Mitochondrial dysfunction (energy disposal failure, apoptosis, etc.), redox disturbances (oxidative stress and enhanced reactive oxygen and nitrogen species production), and excitotoxicity (Glu mediated toxicity) may play an important role in the progression of the disease, causing axonal and neuronal damage. This review focuses on the mechanisms of mitochondrial dysfunction (including mitochondrial DNA (mtDNA) defects and mitochondrial structural/functional changes), oxidative stress (including reactive oxygen and nitric species), and excitotoxicity that are involved in MS and also discusses the potential targets and tools for therapeutic approaches in the future.\n\nID: 27934854\nTitle: Interactions between genetic, lifestyle and environmental risk factors for multiple sclerosis.\nAbstract: Genetic predisposition to multiple sclerosis (MS) only explains a fraction of the disease risk; lifestyle and environmental factors are key contributors to the risk of MS. Importantly, these nongenetic factors can influence pathogenetic pathways, and some of them can be modified. Besides established MS-associated risk factors - high latitude, female sex, smoking, low vitamin D levels caused by insufficient sun exposure and/or dietary intake, and Epstein-Barr virus (EBV) infection - strong evidence now supports obesity during adolescence as a factor increasing MS risk. Organic solvents and shift work have also been reported to confer increased risk of the disease, whereas factors such as use of nicotine or alcohol, cytomegalovirus infection and a high coffee consumption are associated with a reduced risk. Certain factors - smoking, EBV infection and obesity - interact with HLA risk genes, pointing at a pathogenetic pathway involving adaptive immunity. All of the described risk factors for MS can influence adaptive and/or innate immunity, which is thought to be the main pathway modulated by MS risk alleles. Unlike genetic risk factors, many environmental and lifestyle factors can be modified, with potential for prevention, particularly for people at the greatest risk, such as relatives of individuals with MS. Here, we review recent data on environmental and lifestyle factors, with a focus on gene-environment interactions.\n\nID: 27488370\nTitle: Treatment Effects for Dysphagia in Adults with Multiple Sclerosis: A Systematic Review.\nAbstract: Dysphagia or swallowing difficulties have been reported to be a concern in adults with multiple sclerosis (MS). This problem can result in several complications including aspiration pneumonia, reduced quality of life and an increase in mortality rate. No previous systematic reviews on treatment effects for dysphagia in MS have been published. The main objective of this study is to summarise and qualitatively analyse published studies on treatment effects for dysphagia in MS. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were applied to conduct a systematic search of seven databases, using relevant key words, and subsequent analysis of the identified studies. The studies were required to meet all three inclusion criteria of including a statement on intention to treat, or measure the effects of treatment for dysphagia in adults with MS and data on treatment outcomes for at least one adult diagnosed with MS. Retained studies were evaluated by two independent reviewers using a critical appraisal tool. This study has not been registered. A total of 563 studies were identified from the database searches. After screening and assessment of full articles for eligibility, five studies were included in the review. Three examined electrical stimulation and two examined the use of botulinum toxin. One study testing electrical stimulation was a randomised controlled trial, two were well-designed case series and two were case series lacking experimental control. All studies reported some positive effects on dysphagia; however, treatments that involved the use of electrical stimulation showed larger effect sizes. There is a paucity of evidence to guide treatment of dysphagia in MS, with only electrical stimulation and botulinum toxin treatment represented in the literature search conducted here. While both treatments show initial promise for reducing the swallowing impairment, they require further research using well-controlled experimental designs to determine their clinical applicability and long-term treatment effects for dysphagia across different types and severity of MS.\n\nID: 27038587\nTitle: The therapeutic use of cannabinoids: Forensic aspects.\nAbstract: Since 2013 in the Italian market has been introduced the Nabiximols, a drug containing two of the main active cannabinoids: \u0394(9)-tetrahydrocannabinol (\u0394(9)-THC) and cannabidiol (CBD). This drug has been approved in Italy in the treatment of Multiple Sclerosis (MS). It is an oral spray formulation and each puff of 100\u03bcl contains 2.7mg of \u0394(9)-THC and 2.5mg of CBD. In the present study we analyzed urine and blood samples collected from a group of 20 patients treated with Nabiximols in order to evaluate: blood \u0394(9)-THC concentrations in relation to the dose administered and the duration of treatment and the potentiality of this medication to be used for drug habit. The study was conducted on a sample group of patients affected by MS, of both sexes, age: 49-61 years, treated with Nabiximols for short (28 days) or long-term. The results of our study allow affirming that it is unlikely to use this medication for drug habit or to sale it in the black market because of the low blood concentrations available and of its high costs. These statements were confirmed by: (a) the low \u0394(9)-THC concentrations in the pharmaceutical formulation; (b) the low blood concentrations produced by Nabiximols administration, more than 10 times smaller than the blood concentrations known to produce psychotropic effects; (c) the presence of CBD (\u0394(9)-THC natural antagonist); (d) the route of administration (inhaled, not smoked).\n\nID: 42168651\nTitle: Foamy microglia link oxylipins to disease progression in multiple sclerosis.\nAbstract: Multiple sclerosis (MS) is a chronic neuroinflammatory disease in which demyelinating white matter lesions accumulate and expand, driving irreversible disability. Here we identify a distinct population of foamy GPNMB+ microglia/macrophages associated with lesion expansion in secondary progressive MS. Using integrated lipidomic, transcriptomic, proteomic, chemical proteomic and histological analyses of human postmortem MS lesions, we show that lesions containing foamy microglia/macrophages exhibit disrupted lipid metabolism, lysosomal stress and markers associated with heightened phagocytosis and antigen presentation without classical pro-inflammatory signatures. These lesions are enriched for oxylipins, bismonoacylglycerolphosphates and cholesterol esters, and are associated with increased B cell infiltration and IgG1. Monoacylglycerol lipase (MAGL), a lipid-metabolizing enzyme enriched in lesions with foamy microglia/macrophages, emerged as a potential therapeutic target. Inhibition of MAGL promoted lesion recovery and reduced microgliosis in a mouse model of demyelination. Finally, oxylipins in cerebrospinal fluid correlate with the proportion of foamy lesions, suggesting potential biomarkers for progression. Our findings implicate disturbed lipid metabolism in chronic MS pathology and suggest that foamy microglia/macrophages are an interesting cell type to target for progressive disease.\n\nID: 42125982\nTitle: Integrating Genetics and Environment to Find Causal Mechanisms for Multiple Sclerosis.\nAbstract: Genome-wide association studies (GWAS) have identified hundreds of risk loci for multiple sclerosis (MS), but we have limited knowledge of the mechanisms through which genetic variants mediate risk. Similarly, epidemiological studies implicate numerous environmental risk factors in MS risk, but these cannot identify specific causal mechanisms. We review our current knowledge of genetic mechanisms in MS, including the critical role of expression quantitative trait locus (eQTL) mapping in translating genetic risk loci into causal mechanisms. Molecular and functional context has emerged as an important missing component of these studies, and we discuss how environmental risk factors can be modelled in a quantitative genetic context to identify disease mechanisms. In parallel, we highlight recent advances in which quantitative genetic methods establish a causal role for low vitamin D and obesity in MS, and to dissect the mechanisms through which these operate. As genetic, transcriptional, and epigenetic studies continue to expand, further mechanistic insights for MS are likely to come from the integration of genetic and environmental data.\n\nID: 42103229\nTitle: A comprehensive discovery platform for ELOVL1 small-molecule inhibitors targeting very long-chain fatty acid synthesis in adrenoleukodystrophy.\nAbstract: Adrenoleukodystrophy (ALD or X-ALD) is a rare devastating neurological disease caused by mutations in the ATP binding cassette D1 (ABCD1) gene, the product of which is involved in the transport of very long-chain fatty acids (VLCFAs) into peroxisomes for degradation by \u03b2-oxidation. Deficiency in ABCD1 results in VLCFAs accumulation in many tissues, including the brain and spinal cord. Elevated VLCFA levels, specifically C26:0, are consistent biochemical markers of ALD and are implicated in the ALD pathogenesis. ALD disease is manifested by multiple phenotypes: the most severe cerebral disease (cerebral ALD, cALD), adrenomyeloneuropathy (AMN) and adrenal insufficiency (Addison disease). VLCFA accumulation is a hallmark of all ALD phenotypes, and reduction/normalization of VLCFA levels is an attractive approach for the treatment of all ALD manifestations. VLCFAs synthesis involves enzymes from elongase of very long-chain fatty acids (ELOVL) enzyme family with ELOVL1 being a rate-limiting enzyme in C26:0 synthesis, making ELOVL1 an attractive target for medical intervention in ALD via Substrate Reduction Therapy (SRT). In this paper, we describe the in vitro assays established to support medicinal chemistry efforts to develop small-molecule ELOVL1 inhibitors for ALD. Notably, we developed novel, breakthrough in vitro methods to monitor enzymatic and cellular ELOVL1 activity, enabling high-throughput screening (HTS) of Sanofi library collections. We successfully identified CNS-active, small-molecule ELOVL1 inhibitors shown to be efficacious in the reduction of C26:0 VLCFA levels in cells and multiple tissues, including brain and spinal cord, in animal models.\n\nID: 42061910\nTitle: Geographic distribution of mortality from systemic lupus erythematosus.\nAbstract: BackgroundSystemic lupus erythematous (SLE) shares many common epidemiologic features with other autoimmune diseases or diseases associated with an underlying Epstein-Barr virus (EBV) infection. It was hypothesized that the geographic variation of mortality from SLE would reveal a similar pattern as Hodgkin lymphoma (HL), multiple sclerosis (MS), Crohn's disease (CD), and ulcerative colitis (UC).MethodsUsing the vital statistics of 21 countries from 1951-2022, overall and age-specific death rates from the 5 diseases were calculated for each individual country. The death rates of different countries were compared using linear regression analysis.ResultsWhereas other autoimmune diseases or diseases associated with an underlying EBV infection, such as HL, MS, CD, and UC, showed remarkably similar geographic variations, the geographic distribution of SLE did not fit this overall pattern. High death rates from SLE were not clearly associated with developing versus developed countries, northern versus southern latitude, or any specific continent. However, similar geographic distributions of SLE were consistently found among consecutive age groups, ranging from 0-4 to 85+ years.ConclusionsThe similarities in the geographic distributions of death rates from HL, MS, CD, and UC suggest that these 4 diseases share a set of one or more common environmental risk factors. Other environmental risk factors besides EBV infection must contribute to the varying occurrence of SLE across the globe. These risk factors start exerting their influence at a very young age of less than 5\u00a0years.\n\nID: 41889330\nTitle: Interplay between genetic and environmental risk factors in multiple sclerosis: what have we learned?\nAbstract: Genome-wide association studies have identified >230 genetic variants associated with susceptibility to multiple sclerosis and one genome-wide significant variant associated with progression of multiple sclerosis. Environmental risk factors, such as vitamin D deficiency and obesity, have also been implicated in multiple sclerosis pathogenesis. Statistical approaches building on these genetic data, such as Mendelian randomization and co-localization, have established putative causal links between environmental risk factors and multiple sclerosis risk, most notably for vitamin D and body mass index. However, studies have thus far revealed limited statistically significant interactions between host genetics and environmental factors beyond the major histocompatibility complex. Epigenetics (the study of non-nucleotide alterations to DNA, such as DNA methylation or histone acetylation) might provide a mechanistic framework for understanding how environmental and genetic factors interact in multiple sclerosis. Environmental factors, such as Epstein-Barr virus infection, vitamin D deficiency and smoking, are associated with epigenetic modifications at key multiple sclerosis-related genomic loci, altering the expression of multiple sclerosis risk genes in a cell type-specific manner. Transcriptomics have identified significant pathways via which genetic risk is realized, potentially providing targets for intervention. This review synthesizes current evidence on gene-environment interactions in the context of multiple sclerosis genome-wide association study findings, evaluates the strengths and limitations of various study methodologies, and discusses the challenges in elucidating the interplay between genetics and environmental factors. We propose potential strategies for future research to advance our understanding of the biological mechanisms underlying multiple sclerosis susceptibility in at-risk individuals.\n\nID: 41802452\nTitle: Unraveling the role of human endogenous retroviruses in rheumatoid arthritis.\nAbstract: Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by chronic and painful joint inflammation that can lead to bone erosion and significant disability if not treated promptly. The etiology of this disease is not fully defined. Multiple genetic, epigenetic, environmental, and immunological factors have been associated with the development and perpetuation of this autoimmune and inflammatory phenomenon. Human endogenous retroviruses (HERVs), retroelements that comprise approximately 8% of the human genome, have been proposed as potential contributors to the loss of immune tolerance and may contribute to the development of RA. Exposure to certain environmental risk factors, cellular activation processes, and inflammation promotes HERV gene expression. Compared with healthy individuals, RA patients exhibit increased transcripts of particular HERVs in blood and synovium, mainly of the HERV-K family. In addition, autoantibodies targeting distinct HERV epitopes have been identified in patients with RA. A better understanding of the role of HERVs in RA, including their epigenetic dysregulation and their activation of the immune system, could be a relevant basis for developing new tools for the detection, diagnosis, and follow-up of patients, as well as for identifying alternative therapeutic targets in those individuals who are refractory to conventional treatments. This review examines the general features of HERVs and their potential role in the immune dysregulation of patients with RA.\n\nID: 41795504\nTitle: Genetic and environmental mediators of multiple sclerosis susceptibility but not early severity run in families.\nAbstract: Multiple sclerosis (MS) susceptibility and severity are mediated by different genetic and environmental risk factors. Familial aggregation in MS is partially explained by susceptibility determinants, yet impact on early disease course after clinically isolated syndrome (CIS) is uncertain. We investigated associations of reported familial MS with genetic and environmental risk factors, and with clinical presentation and disease course after CIS. CIS participants were included in a prospective cohort within six months after symptom onset. Family history was assessed at baseline. We evaluated weighted genetic risk scores (wGRS) for MS susceptibility, 25-hydroxyvitamin D (25(OH)D) and body mass index (BMI), and determined HLA-DRB1*15:01 and MS severity SNP rs10191329 carriership. Anti-Epstein Barr virus Nuclear Antigen-1 (anti-EBNA1) IgG antibodies and 25(OH)D levels were measured. Disease course associations were estimated with Cox regression. Family members with MS were reported by 81/415 (19.5%) CIS participants. Familial MS was associated with higher MS susceptibility wGRS (7.54 (SD1.17) vs. 7.19 (SD1.22), p=0.04) and more frequent HLA-DRB1*15:01 carriership (first-degree 66.7%, other-degree 30.2%, no 38.4%, p=0.02). Anti-EBNA1 IgG and 25(OH)D levels did not differ, yet wGRS for lower 25(OH)D and higher adult BMI characterised MS participants with first-degree MS relatives. Baseline characteristics and disease severity measures were similar between participants with and without familial MS. Our results confirm that familial MS is associated with enrichment of genetic risk for MS susceptibility, low 25(OH)D and high BMI, but not with early disease course after CIS. These data support that MS susceptibility and disease course are driven by different pathophysiological processes.\n\nID: 41780625\nTitle: Mechanisms of environmental risk factors for autoimmune diseases.\nAbstract: Over the past few decades, autoimmune diseases have seen a steady upsurge in global prevalence and associated costs. While the exact reasons for these increases are unknown, this trend has been attributed to increased exposure to environmental agents that are also risk factors for autoimmune disease, including xenobiotic chemicals, infections, lifestyle changes, stressful life events, and altered microbiomes, with subsequent biochemical modifications that influence immune tolerance. This review explores current understanding of mechanisms relating to environmental agents contributing to autoimmune diseases. Here we focus on the key initial mechanistic pathways that include environmentally-induced DNA damage, epigenetic alterations, protein post-translational modifications - such as hapten formation, altered autoantigen structure and cellular locations - tissue barrier disruptions, molecular mimicry, and neuroendocrine dysregulation. The processes by which these initial effects result in secondary changes to influence immunological mechanisms, which can then contribute to the development of autoimmunity and autoimmune disorders, are also discussed. While understanding of the mechanisms of environmental triggers in autoimmune diseases has expanded in recent years, and they are considered fundamental architects of autoimmune phenotypes that imprint specific molecular signatures with prognostic and therapeutic value, many important issues remain unaddressed. These include conducting longitudinal exposome studies, defining the necessary and sufficient gene-environment interactions, understanding the synergistic effects of exposure mixtures, of exposure timing and susceptibility, and impacts of chronic psychosocial stress on immune function. Addressing these knowledge gaps and advancing our understanding of the underlying causal pathways are vital for developing preventive strategies and creating safer and more effective therapies for autoimmune conditions.\n\nID: 41764304\nTitle: MALDI-TOF mass spectrometry imaging of sulfatide lipid expression in the CNS of mice with experimental autoimmune encephalomyelitis.\nAbstract: Changes in the composition and distribution of the lipids comprising the myelin sheath surrounding neuronal axons have been under-explored in neuroinflammatory diseases such as multiple sclerosis due to the complexities in the analysis of lipids in biological tissues. The application of mass spectrometry-based molecular imaging enables the study of the molecular components of demyelinating tissue. This provides a much better understanding of the complex molecular processes involved in lipid metabolism and the underlying neuroinflammatory demyelinating processes. Uncovering alterations in the lipid profiles during the demyelination processes can potentially elucidate new molecular targets for novel MS drug therapies. We have utilized mass spectrometry imaging (MSI) of in-situ sulfatide lipids in mouse CNS tissue to reveal their spatial distribution and relative abundance. We show that they are generally confined to the white matter region of the cerebellum. We provide a molecular snapshot of lipid alterations at different disease stages of experimental autoimmune encephalomyelitis (EAE), the animal model for MS. Our results suggest that alterations in sulfatide expression are greatest prior to the onset of clinical disease symptoms and are systemic through the white matter and not restricted to the focal inflammatory lesions pathognomonic of EAE and human MS. The lipid mass maps generated by MSI provide novel insights into the dynamics of lipid alterations during neuroinflammation.\n\nID: 41759699\nTitle: Astragalus polysaccharide ameliorates neuroinflammation in EAE mice by modulating microglial autophagy to reduce lipid droplet accumulation.\nAbstract: Multiple sclerosis (MS) is an immune-mediated inflammatory demyelinating disease of the central nervous system. Emerging evidence indicates a close association between lipid metabolism disorders and MS, wherein microglial neuroinflammation driven by aberrant lipid droplet accumulation represents a core pathological mechanism. In this study, we first performed GEO database-based differential gene enrichment analysis related to lipid metabolism and GWAS-based Mendelian randomization analysis, demonstrating that disordered lipid metabolism constitutes a key pathological feature of MS with lipid droplets playing a central role. Based on these findings and our previous work demonstrating the efficacy of APS in alleviating neuroinflammation and neurological deficits in experimental autoimmune encephalomyelitis (EAE) mice, we sought to elucidate its role and mechanism in regulating microglial lipid droplets metabolism and neuroinflammation in the EAE mice and LPS-stimulated BV2 microglia model. Results demonstrated impaired autophagic flux, increased lipid droplets accumulation, and elevated pro-inflammatory cytokine secretion in both EAE mice brain tissue and LPS-stimulated BV2 microglia model. Critically, APS intervention reversed these pathological changes. APS activated microglial autophagic flux, enhanced lipophagy function, cleared accumulated lipid droplets, and consequently suppressed pro-inflammatory factor secretion, thereby alleviating neuroinflammation. In conclusion, APS alleviates MS neuroinflammation partially by enhancing microglial lipophagy, which facilitates the elimination of lipid droplets accumulation. This finding provides a novel therapeutic strategy and lays a theoretical foundation for developing neuroprotective drugs targeting lipophagy.\n\nID: 41744049\nTitle: Exploring Sex-Based Mechanisms of Inflammation and Neurodegeneration in Multiple Sclerosis.\nAbstract: Multiple sclerosis (MS) is a chronic autoimmune disease of the central nervous system (CNS) characterized by both immune-mediated inflammation and progressive neurodegeneration. While both processes occur in all individuals with MS, females more often present with heightened inflammatory activity, whereas males tend toward accelerated neurodegeneration and disability progression. This review synthesizes current evidence on biological, hormonal, genetic, epigenetic, and environmental mechanisms underlying sex-based differences in relapsing-remitting MS (RRMS), the most common MS subtype. We integrate findings from human studies, animal models, and molecular research to examine the contribution of genetics and epigenetic regulation including sex chromosomes, single nucleotide polymorphisms (SNPs), and microRNAs (miRNAs) to MS pathophysiology. We discuss the influence of sex hormones, including estrogen, progesterone, and testosterone, and environmental risk factors such as Epstein-Barr virus infection and vitamin D3 deficiency. Evidence suggests that X-linked immune-related genes, hormone - immune interactions, and sex-specific epigenetic regulation shape differential immune responses and neuronal vulnerability in males and females with MS. miRNAs emerge as critical molecular bridges linking genetic susceptibility, hormonal milieu, and environmental exposures to downstream inflammatory and neurodegenerative pathways. Understanding the mechanisms driving sex differences in MS may enable the development of targeted interventions addressing both neuroinflammation and neurodegeneration. Integrated miRNA - mRNA analyses, explicitly powered to assess sex as a biological variable, hold promise for identifying novel biomarkers and therapeutic targets. Such approaches could inform more personalized treatment strategies and improve long-term outcomes for all people with MS.\n\nID: 41699693\nTitle: Spatial characterisation of TREM2 expression in actively demyelinating multiple sclerosis lesions supports its key roles in lipid metabolic pathways.\nAbstract: Reactive macrophages and microglia are predominant myeloid cell types in demyelinating multiple sclerosis (MS) lesions in the central nervous system (CNS). Triggering receptor expressed on myeloid cells-2 (TREM2) promotes clearance of myelin debris, supporting remyelination in preclinical models. However, the relevance of TREM2 in people with MS is less understood. We evaluated TREM2 expression and function in autopsy CNS tissues from individuals with and without MS. Spatial transcriptomics and gene co-expression network analysis revealed TREM2 expression in chronic active MS lesioned white matter, where it was localised to glial cell rich clusters associated with lipid and cholesterol metabolism, cellular heat acclimation pathways, and regulation of oligodendrocyte precursor migration and differentiation. Immunofluorescence analysis confirmed that TREM2 was highly expressed in actively demyelinating MS white matter lesions (active lesion centres and chronic active lesion rims). In these areas, TREM2 was found in reactive microglia, perivascular macrophages, and infiltrating parenchymal macrophages. Similarities were observed between perilesional white matter (PLWM) and chronic active lesion rims, including presence of TREM2+ reactive microglia, which were rare in normal appearing white matter (NAWM). TREM2+ cells co-expressed microglia/macrophage markers Iba1, MHC class II, MS4A4A, CD68 and/or CD163, and PLIN2, a lipid storage marker. Almost all TREM2+ cells in active demyelinating white matter were also PLIN2+, while these cells were absent in NAWM. Abluminal TREM2+ PLIN2+ CD163+ vessel macrophages were particularly prominent in actively demyelinating MS white matter where they may play important roles in lipid metabolism and storage in the context of active demyelination. These findings highlight the involvement of TREM2 on both resident and infiltrating myeloid cell populations in response to the demyelinating insult within MS lesions that may directly or indirectly impact local oligodendrocyte myelination capacity and neuroprotection.\n\nID: 41661343\nTitle: Serum neurofilament light chain and glial fibrillary acidic protein predicting multiple sclerosis after clinically isolated syndrome.\nAbstract: Serum neurofilament light chain (NfL) and glial fibrillary acidic protein (GFAP) may synergistically enhance early risk stratification of multiple sclerosis (MS) diagnosis after clinically isolated syndromes (CIS). We investigated the prognostic value of combined NfL and GFAP for McDonald 2024 MS diagnosis after CIS and associations with key genetic and environmental risk factors. CIS participants, within six months after symptom onset, were included in a prospective cohort. We measured baseline serum NfL and GFAP levels and calculated z-scores. We evaluated weighted genetic risk scores for MS susceptibility, HLA-DRB1*15:01 risk and measured Anti-Epstein Barr virus Nuclear Antigen-1 (anti-EBNA1) immunoglobulin G (IgG) antibodies. Associations with MS diagnosis were evaluated using Cox proportional hazards models and time-dependent receiver operating characteristic (ROC) analyses. During follow-up, 162/221 CIS participants were diagnosed with McDonald 2024 MS. Separately, high NfL and GFAP associated with earlier MS diagnoses (hazard ratio (HR) 1.36, 95% confidence interval (CI) 1.12-1.66, p\u2009=\u20090.002, HR 1.12, 95% CI 1.02-1.42, p\u2009=\u20090.01, respectively). In combined models, only NfL remained independently predictive (HR 1.30, 95% CI 1.02-1.60, p\u2009=\u20090.01). Time-dependent ROC analyses showed similar results for NfL alone and combined with GFAP. HLA-DRB1*15:01-risk, but not GFAP or anti-EBNA1 IgG, improved predictive value. Our study found that serum NfL outperformed GFAP in predicting early MS diagnoses after CIS. Baseline NfL, together with HLA-DRB1*15:01 status, provides robust early risk stratification for MS after CIS, whereas GFAP and anti-EBNA1 titres add limited prognostic value. Additional immunological and imaging markers are essential to further refine predictive models.\n\nID: 41649970\nTitle: Pediatric-Onset Multiple Sclerosis in Multiple Autoimmune Syndrome: Reporting This Rare Entity in 2 Pediatric Patients.\nAbstract: Multiple autoimmune syndrome (MAS) is characterized by the coexistence of 3 or more autoimmune disorders in the same individual and is exceptionally rare in childhood. Pediatric-onset multiple sclerosis (POMS) represents 3% to 5% of all multiple sclerosis (MS) cases and is increasingly recognized within the broader spectrum of immune-mediated diseases. We describe 2 pediatric patients fulfilling MAS criteria in association with POMS-one with type 1 diabetes mellitus and autoimmune thyroiditis, and another with rheumatoid arthritis and autoimmune thyroiditis. Both exhibited HLA-DRB1*15:01 positivity, Epstein-Barr virus IgG seropositivity, and severe vitamin D deficiency, suggesting shared immunogenetic and environmental risk factors. These cases highlight the potential of POMS to manifest as part of a systemic autoimmune diathesis. Early recognition, proactive screening, and multidisciplinary management are essential. Further multicenter studies and registry-based data are needed to clarify the prevalence, mechanisms, and prognostic implications of MAS in pediatric MS.\n\nID: 41615844\nTitle: Bidirectional relationship between mitochondrial dysfunction and dysregulated lipid metabolism in Multiple Sclerosis: potential mechanisms and therapeutic implications.\nAbstract: Multiple Sclerosis (MS) is a heterogeneous neuroinflammatory disease with complex aetiology and diverse clinical presentations, often accompanied by neurodegenerative pathology. While current therapies primarily focus on immunomodulation, emerging evidence underscores a critical bidirectional interplay between mitochondrial dysfunction and lipid dysregulation in driving MS progression. Understanding this metabolic-mitochondrial axis may reveal novel therapeutic opportunities beyond immune modulation. This scoping review systematically maps recent literature (2015-2025) to delineate the mechanistic connections between mitochondrial dysfunction and lipid dysregulation in MS, identify current knowledge gaps, and highlight translational opportunities for targeted intervention. A systematic search of PubMed, Embase, and Scopus was conducted in 2025 following PRISMA-ScR guidelines. Thirty-six eligible studies examining mitochondrial-lipid interactions in human MS and preclinical models were included and synthesised thematically. Evidence converges on a self-reinforcing pathological cycle in MS, where dysregulated lipid metabolism impairs mitochondrial integrity, amplifying reactive oxygen species generation, energy failure, and further lipid disruption. This cascade contributes to oligodendrocyte injury, demyelination, ferroptosis, and axonal degeneration. Importantly, therapeutic strategies that restore lipid-mitochondrial homeostasis, such as mitochondrial antioxidants, lipid modulators, and metabolically active immunotherapies, demonstrate promising neuroprotective effects in preclinical studies. The evidence supports a model in which the bidirectional feedback loop between mitochondrial dysfunction and lipid dysregulation represents a significant mechanism contributing to neurodegeneration in MS. Clinically, these insights highlight opportunities for earlier diagnosis and more personalised disease management through the integration of lipid-based biomarkers into patient monitoring and treatment selection. Targeting this metabolic axis holds significant promise for developing next-generation disease-modifying therapies to slow disease progression, enhance neuroprotection, and improve functional recovery across different MS subtypes.\n\nID: 41611866\nTitle: Environmental risk factors and conversion to multiple sclerosis in subjects with radiologically isolated syndrome: a case-control study.\nAbstract: Radiologically isolated syndrome (RIS) is the incidental finding of lesions typical for multiple sclerosis (MS) on magnetic resonance imaging in asymptomatic individuals. We investigated which environmental factors are associated with a first clinical event in RIS patients. Subjects presenting as RIS (cases) or as clinically isolated syndrome (CIS)/relapsing-remitting multiple sclerosis (RRMS) at onset (controls) were included. Patients were administered an environmental questionnaire. The distribution of clinical and demographic characteristics and environmental factors was analysed. RIS subjects were divided according to time of conversion to MS and clinical and demographic characteristics and environmental factors were investigated as risk factors for conversion. Fifty-two RIS and 216 controls were included. Controls were younger at diagnosis (33.4 vs 39.0 years old), while RIS patients had more frequent onset with supratentorial symptoms (26.9% vs 8.3%). Spending more time outdoor during childhood was associated with a higher risk of a CIS/RRMS onset (odds ratio (OR) 0.24, 95% confidential interval (CI): 0.09-0.65, p\u2009=\u20090.0049). RIS that converted within 5 years were more likely to be underweight during adolescence (hazard ratio (HR) 11.57, 95% CI: 2.45-54.61, p\u2009=\u20090.0020), to have had pregnancy losses (HR 4.48, 95% CI: 1.35-14.88, p\u2009=\u20090.0145) and to have used assisted reproduction technology (ART) before RIS diagnosis (HR 20.42, 95% CI: 2.82-147.82, p\u2009=\u20090.0028). Being underweight during adolescence, the use of ART and a history of pregnancy losses led to a higher risk of conversion from RIS to MS. Outdoor activity during childhood was more frequent in patients with CIS/RRMS.\n\nID: 41596461\nTitle: The Role of Lipid Alteration in Multiple Sclerosis.\nAbstract: Multiple sclerosis (MS) is traditionally recognized as a chronic immune-mediated disorder of the central nervous system (CNS), but increasing evidence suggests that systemic metabolic alterations may also contribute to its pathophysiology. Lipid abnormalities in MS have recently attracted renewed research interest, with studies focusing both on dysregulation of lipid signaling pathways and on alterations in standard lipid profile components, including total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides (TG), and non-HDL cholesterol. Although disturbances in serum lipid profiles are consistently reported in patients with MS, their origin remains unresolved. Emerging data indicate that dyslipidemia may stem from aberrant cholesterol metabolism within the CNS, secondary to demyelination and myelin sheath destruction, leading to the release of lipid-rich debris and subsequent systemic metabolic imbalance. These lipid changes appear to correlate with blood-brain barrier (BBB) dysfunction, suggesting a link between peripheral lipid metabolism and CNS inflammation. This review summarizes current knowledge on the mechanisms underlying dyslipidemia in MS, its potential impact on disease progression, and its relevance as a possible therapeutic or biomarker target in future translational studies.\n\nID: 41526136\nTitle: Immunotherapies in progressive multiple sclerosis.\nAbstract: Multiple sclerosis (MS) is an autoimmune disease of the central nervous system, with both genetic and environmental risk factors. While traditionally, a relapsing and progressive disease course has been distinguished, it has increasingly become evident that elements of progression are the dominant factor for accumulating MS-related neurologic disability across all clinical courses and can be detected throughout the full disease trajectory in patients with MS. Therefore, defining the dominant pathophysiologic processes driving progression has become indispensable. Pathologic hallmarks of progressive MS include a compartmentalized inflammation within the central nervous system as well as associated neurodegenerative processes, finally leading to neuroaxonal and synaptic loss. Growing understanding of the pathophysiology has led to the development of an increasing number of targeted immunomodulatory treatment approaches for progressive MS. With the development of novel clinical trial designs and the evolution of clinical and paraclinical measures allowing accurate and rapid assessment of progression, new opportunities for personalized treatment regimens are likely to emerge.\n\nID: 41506767\nTitle: Chinese neuroimmunological disease (NIDBase) cohort study: cohort profile.\nAbstract: The Chinese neuroimmunological disease database (NIDBase) cohort was established to explore genetic and environmental risk factors, clinical features, multi-omics data and prognostic biomarkers. The aim is to enhance our understanding of central nervous system (CNS) demyelinating diseases. Additionally, the establishment of this cohort will address the critical issue of the lack of comprehensive genetic data and biological samples for precision diagnosis and treatment research related to neuroimmunological diseases in China. 56 hospitals in various regions of China were selected to participate in this study. The patients diagnosed with CNS demyelinating diseases were recruited, including clinically isolated syndrome (CIS), multiple sclerosis (MS), neuromyelitis optica spectrum disease (NMOSD), myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) and autoimmune glial fibrillary acidic protein astrocytopathy (GFAP-A). At the time of patient enrolment, the clinical information is designated as baseline data. The collected baseline data include demographic information, disease history, clinical features of each demyelinating event, treatment records, standardised scales, questionnaire assessments and laboratory test results. Furthermore, biological samples, MRI and high-density electroencephalography (hd-EEG) data will be collected at baseline. All patients will be followed up at 3 months and 6 months and annually thereafter. As of December 2024, 3866 patients with CNS demyelinating diseases have been enrolled, including 84 CIS, 282 MOGAD, 1405 MS and 2095 NMOSD. Our findings indicate that CNS demyelinating diseases, particularly NMOSD, are more prevalent in women in China, with significant age differences observed among NMOSD patients compared with those with CIS, MS and MOGAD. In future, all patients in our cohort will be followed up at 3 months and 6 months and then annually. By the end of December 2024, the database has been locked and is now being processed and analysed, while our data continue to be updated and expanded for further analysis. Both prospective and retrospective observations will be included in this study. Subsequent publications will emerge from this multicentre cohort, encompassing genomics, clinical cohort studies, hd-EEG biomarkers, imaging-based radiomics and electrical stimulation therapies.

The present analysis serves to test whether the time trends of systemic lupus erythematous (SLE) in England & Wales and the United States are characterized by a similar birth-cohort patterns as other autoimmune diseases associated with Epstein-Barr virus (EBV).MethodsIn an observational study using the Vital Statistics of England & Wales and the United States from 1951 to 2022, the mortality trends of SLE were compared to those of Hodgkin lymphoma (HL), multiple sclerosis (MS), Crohn's disease (CD), and ulcerative colitis (UC).ResultsMortality from SLE rose among generations born during the 19th century and decreased among generations born subsequently during the 20th century. This birth-cohort pattern of SLE was matched by almost identical patterns underlying the occurrence of MS and CD, whereas mortality from HL and UC were similarly characterized by a birth-cohort patterns with a rise and fall in mortality that were shifted by 10-20\u00a0years towards earlier generations when compared to SLE, MS, and CD.ConclusionThe similarities in the birth-cohort patterns of SLE and other EBV-associated diagnoses suggest that they all share a common risk factor, such as EBV infection. The trends of SLE may have been shaped by underlying trends in the acquisition of EBV infection during adolescence or early adulthood.\n\nID: 41454472\nTitle: Toward a global research agenda for preventing multiple sclerosis.\nAbstract: Considerable progress has been made in understanding genetic and environmental risk factors for multiple sclerosis (MS), yet we still cannot prevent MS. To drive progress in primary and secondary prevention of MS by developing a comprehensive research agenda based on current knowledge. A global workshop convened people with lived experience, clinicians, researchers, and policymakers with expertise in MS, other chronic diseases, epidemiology, clinical trials, genomics, immunology, virology, behavioral science, and public health to develop pathways to advance the MS prevention agenda. Regarding primary prevention, workshop participants recommended acting on known modifiable risk factors; identifying novel etiological factors and determining how they lead to disease; and building coalitions including organizations with shared interests. Regarding secondary prevention, workshop participants recommended identifying biomarkers relevant from initial immune dysregulation through to initial clinical presentation, linking biomarkers to long-term MS outcomes, developing cost-effective screening tools for MS and point-of-care testing, and developing prodromal criteria for MS that could be implemented clinically. Communication and evaluation frameworks, adoption of an implementation mind-set, and engagement of public health were highlighted as key supporting elements. This workshop sets the stage for developing a global prevention agenda for MS.\n\nID: 41317369\nTitle: Inflammatory bowel disease therapies and demyelinating diseases: a practical guide to therapeutic benefit and risk.\nAbstract: Demyelinating diseases, particularly multiple sclerosis (MS), present a unique therapeutic challenge in the management of inflammatory bowel disease (IBD). Although rare, the co-occurrence of IBD and demyelinating disorders is well-documented and may reflect shared immune, genetic, and environmental risk factors. As the therapeutic landscape of IBD expands to include biologics and small molecules that target immune pathways also implicated in MS, concerns around neurological safety have grown. In particular, anti-tumor necrosis factor agents have been consistently linked to new-onset or worsening demyelinating events, while other treatments such as sphingosine-1-phosphate receptor modulators and natali-zumab are licensed for both IBD and MS, though real-world data in patients with coexisting disease remain limited. This review synthesizes current evidence regarding the neurological safety and efficacy of IBD therapies in the context of demyelinating disease. It proposes a practical framework for clinicians, addressing management strategies for patients with confirmed MS, those at increased risk, and individuals who develop neurological symptoms during treatment. In the absence of formal guidelines, multidisciplinary collaboration, early recognition of symptoms, and careful treatment selection are important to optimize both gastrointestinal and neurological outcomes.\n\nID: 41305282\nTitle: Development and Usability of MSafe: A Fall Risk Application for Older Adults with Multiple Sclerosis.\nAbstract: Background: Falls are highly prevalent in older adults with Multiple Sclerosis (MS) and stem from a complex interplay of physiological, psychosocial, cognitive, and environmental risk factors. Fall risk assessments rely on in-person visits and occur infrequently, but mobile technology can provide portable, cost-effective, and multifactorial screening. The purpose of this study was to develop and evaluate the usability of a multifactorial fall risk app (MSafe) for older adults with MS. Methods: MSafe consists of 37 self-report questions, 9 quantitative cognitive and mobility assessments, and a final fall risk report. One-on-one semi-structured interviews were conducted with 21 older adults (>55) with MS. Participants independently used MSafe, were asked about their likes and dislikes, and completed the System Usability Scale (SUS). Interviews were video-recorded, transcribed, and coded into themes. Results: Three themes emerged: (1) simplicity of use, (2) progress monitoring, and (3) guidance and support. Overall, participants found MSafe easy to use, valuable to track and monitor their fall risk, and either confirmed or increased awareness of their own abilities. SUS scores averaged 84.9 \u00b1 14.7. Conclusions: MSafe is a comprehensive fall risk app that demonstrated high usability by older adults with MS. Future steps include implementing MSafe in home settings to examine fall risk management.\n\nID: 41272208\nTitle: Spatial lipidomics reveals altered lipid profiles in TMEM63A mutant rats with hypomyelination.\nAbstract: Hypomyelinating leukodystrophies (HLDs) are genetic disorders characterized by deficient myelination. While TMEM63A variants are associated with HLD19, the specific lipid alterations in affected brain regions remain to be fully characterized. This study aimed to investigate the spatial distribution of lipid changes in a Tmem63a mutant rat model of hypomyelination. A homozygous Tmem63a c.500G\u2009>\u2009A p.(G167E) knock-in rat model (Tmem63aG167E/G167E) was established. Brain sections from Tmem63aG167E/G167E and Tmem63aWT rats (n\u2009=\u20093/group) were analyzed using MALDI-MSI for lipid profiling across nine distinct brain regions. Myelin structure was characterized by transmission electron microscopy (TEM) and g-ratio quantification. Statistical analyses included Mann-Whitney U tests for g-ratio distributions and ROC analysis for feature screening. Out of 702 analyzed features, 124 were differentially expressed. Lipids constituted the most altered class (43 features), including 22 glycerophospholipid, 9 fatty acid, 5 sphingolipid, 5 sterol lipid, and 2 prenol lipid species. These alterations were predominantly observed in white matter-rich regions and gray-white matter junctions. TEM revealed thinner and less dense myelin sheaths in Tmem63aG167E/G167E rats, with a reduced proportion of optimal g-ratios. This study provides a comprehensive spatial lipidomic characterization in a Tmem63a mutant rat model, revealing significant lipid alterations associated with hypomyelination. These findings offer new insights into the pathology of hypomyelination and highlight specific lipid species for future investigation.\n\nID: 42405595\nTitle: Uric Acid Released from Poly (Lactic-co-Glycolic Acid) Nanoparticles Mitigates Glutamate-Induced Excitotoxicity of Spinal Cord Neurons.\nAbstract: Spinal cord injury (SCI) is often compounded by secondary damage caused by glutamate-induced excitotoxicity (GIE), where excessive glutamate release results in neuronal damage by overstimulation of glutamate receptors. This process leads to mitochondrial dysfunction, oxidative stress, and neuronal death. Uric acid (UA) has been identified as a potential neuroprotective molecule due to its antioxidant properties, but its limited solubility poses challenges for clinical use. To address this issue, we encapsulated UA in poly (lactic-co-glycolic acid) nanoparticles (UA-NPs) using a modified double emulsion technique to enhance stability and delivery of UA. Spinal cord cultures were subjected to GIE, followed by treatment with UA-NPs or empty nanoparticles. Neuronal survival was assessed with immunocytochemistry for the neuronal marker microtubule-associated protein 2 (MAP2), which revealed that treatment with UA-NPs resulted in significantly higher cell survival compared to cultures treated with empty nanoparticles. These findings suggest that UA-NPs provide neuroprotection to spinal cord neurons in\u00a0vitro and may serve as a promising localized drug delivery system for SCI treatment, offering a targeted approach to mitigate secondary injury. Spinal cord injuries can cause long-term damage not only from the initial injury but also from secondary injury processes that worsen the condition over time. One of these processes involves glutamate, an important neurotransmitter normally present in cells. However, when released in excess, glutamate can overstimulate nearby neurons and lead to damage and death of nerve cells. This process can harm essential cell functions, increase stress within cells, and reduce their ability to survive. Uric acid is a natural substance in the body that can help protect cells because of its antioxidant properties. However, it does not dissolve well in water-based solvents, including blood, making it difficult to use as a treatment. To overcome this problem, we packaged uric acid into tiny particles called nanoparticles, which improve its stability and delivery to cells. In this study, we tested our uric acid-loaded nanoparticles on spinal cord cells after exposing them to harmful conditions similar to those seen after injury. We found that cells treated with these nanoparticles survived better than those treated with empty particles. These results suggest that delivering uric acid using nanoparticles may help protect nerve cells after spinal cord injury. This approach could lead to more effective treatments that target and reduce further damage after the initial injury.\n\nID: 42123634\nTitle: Exploring Neuroprotective Potential of Bioactive Compounds Obtained from Artichoke By-Products by Pressurized Liquid Extraction via Response Surface Methodology.\nAbstract: Artichoke by-products (ABP) represent valuable sources of bioactive compounds with relevant health benefits. In this study, a green extraction strategy based on pressurized liquid extraction (PLE) was optimized to enhance the recovery of phenolic and flavonoid compounds from ABP using a response surface methodology. Extraction temperature and solvent composition were identified as the key factors driving extraction performance. Optimal conditions using a mixture of ethyl acetate and ethanol (90/10, v/v) at 180 \u00b0C significantly enhanced extraction yield, total phenolic and flavonoid content, and antioxidant activities, as measured by ORAC and DPPH assays. Chemical characterization via HPLC-C18-Q-TOF-MS/MS revealed a diverse profile of phenolic and flavonoid compounds, including caffeoylquinic acid derivatives and related transformation products. The neuroprotective potential of the optimized extract was further evaluated through in vitro inhibition assays targeting acetylcholinesterase (AChE), butyrylcholinesterase (BChE) and lipoxygenase (LOX), alongside a permeability assessment using an in vitro blood-brain barrier (BBB) model. Molecular docking simulations were performed to explore the interactions of apigenin-the most representative flavonoid in the optimal extract-with the three target enzymes. Overall, these findings support the valorization of ABP as a source of bioactive compounds and highlight the potential of PLE as an efficient and sustainable extraction approach.\n\nID: 41687739\nTitle: Protective effects of sodium benzoate against toluene-induced reward enhancement, behavioral disturbances, and impaired synaptic plasticity in mice.\nAbstract: Toluene is one of the most commonly abused solvents. Inhibition of N-methyl-D-aspartate receptor (NMDAR) has been linked to the rewarding and behavioral effects of toluene. One of the avenues to enhance NMDAR function is to increase the levels of D-serine via inhibiting D-amino acids oxidase (DAAO) activity. The present study determined whether sodium benzoate, a DAAO inhibitor, could counteract the toluene-induced brain stimulation reward enhancement, behavioral disturbances, and hippocampal synaptic dysfunction after acute toluene exposure. Male mice received various doses of sodium benzoate before toluene exposure for assessment of intracranial self-stimulation (ICSS) thresholds, rotarod test, novel object recognition task, social interaction test, and long-term potentiation (LTP) and long-term depression (LTD) of hippocampal synaptic transmission. Sodium benzoate prevented the lowering of ICSS thresholds, motor incoordination, social withdrawal, object recognition memory deficit, and impaired LTP and LTD induced by toluene. These results indicate that sodium benzoate could ameliorate toluene-induced facilitation of brain reward function, behavioral disturbances, and synaptic plasticity impairment, suggesting that sodium benzoate may be a promising compound against acute toluene intoxication caused by unintentional or deliberate inhalation.\n\nID: 41581769\nTitle: From clinical observation to experimental validation: Investigating the neurotoxic impact of dimethylacetamide.\nAbstract: Dimethylacetamide (DMAC) is a polar organic solvent widely used in the production of synthetic fibers and other industrial applications. Its hepatotoxic potential has been well documented in laboratory animals and occupationally exposed workers, establishing DMAC as a recognized industrial hazard. However, evidence regarding its neurological effects remains scarce. We report a clinical case of accidental DMAC inhalation associated with diffuse cortical hyperintensity on brain magnetic resonance imaging, raising concern for direct neurotoxicity. To address this knowledge gap, we investigated the neurotoxic potential of DMAC in a controlled rat model experiment. Animals subjected to repeated intraperitoneal DMAC administration exhibited cortical and subcortical histopathological alterations consistent with neurotoxicity, accompanied by significant hepatic and renal injury. These findings provide the first experimental evidence that DMAC toxicity extends beyond hepatotoxicity to involve the central nervous system and kidneys, highlighting its potential for multi-organ toxicity and reinforcing concerns regarding occupational exposure risks.\n\nID: 41459648\nTitle: Biophysical basis for brain folding and misfolding patterns in ferrets and humans.\nAbstract: A mechanistic understanding of neurodevelopment requires us to follow the multiscale processes that connect molecular genetic processes to macroscopic cerebral cortical formations and thence to neurological function. Using MRI of the brain of the ferret, a model organism for studying cortical morphogenesis, we create in vitro physical gel models and in silico numerical simulations of normal brain gyrification. Using observations of genetically manipulated animal models, we identify cerebral cortical thickness and cortical expansion rate as the primary drivers of dysmorphogenesis and demonstrate that in silico models allow us to examine the causes of aberrations in morphology and developmental processes at various stages of cortical ontogenesis. Finally, we explain analogous cortical malformations in human brains, with comparisons with human phenotypes induced by the same genetic defects, providing a unified perspective on brain morphogenesis that is driven proximally by genetic causes and affected mechanically via variations in the geometry of the brain and differential growth of the cortex. The wrinkled and folded surface of the human brain is both iconic and familiar. These folds allow a large cortical surface area to fit inside the skull and are essential for healthy brain function. The folds form during development when the brain\u2019s outer layer \u2013 the cerebral cortex \u2013 grows faster than the tissue beneath it, causing the surface to buckle. When this process is disrupted, the brain can develop abnormal folding patterns known as malformations of cortical development. In humans, these conditions are associated with epilepsy, intellectual disability and developmental delay. Studying how such malformations arise is challenging because human brain folding occurs before birth. To address this, researchers use animal models. The ferret is particularly valuable because its brain develops folds similar to those in humans, and many genes linked to human cortical malformations produce comparable folding defects in ferrets. Choi et al. wanted to find out whether the wide range of brain folding abnormalities seen in ferrets and their homologs in humans could be explained by changes in just a few physical properties of the developing brain. Specifically, they tested whether mutations linked to human cortical malformations alter the thickness or growth rate of the cortex. This question is important because different genetic syndromes often result in surprisingly similar brain shapes. By combining brain imaging, computer simulations, and physical gel models of brains that fold when their surfaces absorb solvents and swell (similar to how fingertips swell and wrinkle when wetted for a while), Choi et al. showed that normal brain folding in ferrets can be explained by mechanical forces generated during cortical growth. Both physical experiments with gels and computer simulations of brains with varying cortical thickness or growth rates reproduced folding patterns seen in both healthy and genetically altered ferret brains and their human homologs. Local thinning of the cortex generated many small, tightly packed folds, resembling polymicrogyria, a condition linked to mutations such as those affecting the gene SCN3A, which encodes instructions to form a sodium channel. Reducing overall growth produced smaller, less folded brains similar to microcephaly, which is associated with genes such as ASPM. In contrast, weaker folding with shallow grooves \u2013 characteristic of lissencephaly \u2013 emerged when growth was reduced and cortical thickness increased, as seen with disruptions to genes such as TMEM161B. These results suggest that diverse human genetic disorders converge on common physical mechanisms that shape the brain. The work of c provides a unifying framework linking specific genes to brain shape through physical growth processes. The ferret provides a useful model organism with direct implications for human brain development and misfolding. In the future, it could help researchers interpret human brain scans and understand why different genetic disorders lead to similar malformations. However, before such insights can inform clinical practice, the models will need to incorporate additional biological detail and examine how altered folding affects brain function. More broadly, the paper also raises the question of how variations in brain folding patterns arise in non-human brains, which is the subject of a related study.\n\nID: 41392123\nTitle: Inhalation of 1-bromopropane alters hippocampal expression of pathways related to immune system/inflammation and insulin signaling in experimental rats.\nAbstract: 1-Bromopropane, an alternative to ozone-depleting solvents, exhibits neurotoxicity in humans and rats. The aim of the present study was to identify the genes or signaling pathways involved in the neurotoxicity and hepatotoxicity of 1-bomopropane in two inbred strains of rats. F344 rats and WNA/NUM rats were exposed to 1-bromopropane or filtered air by inhalation for either a single 8-hour session, or 8 h daily for 4 weeks. Motor nerve conduction velocity and distal latency were measured in the tail. At the end of the experiment, the animals were decapitated, and the hippocampus, liver, and blood were collected. Exposure to 1-bromopropane for 4 weeks increased distal latency in the tail nerve significantly in F344 and marginally in WNA/NUM. It also increased total and direct bilirubin in both rat strains. Eight-hour exposure increased metallothionein 2A, metallothionein 1 and NAD(P)H quinone dehydrogenase 1 expression in the liver of both rat strains, whereas 4-week exposure upregulated glutathione S-transferase alpha 3 and CD36 molecule in the liver of both strains. KEGG analysis showed that 8-hr 1-bromopropane upregulated pathways of apoptosis, NOD-like receptor signaling and colorectal cancer, in both the hippocampus and liver, whereas 4-week exposure upregulated NOD-like receptor signaling pathway both in the hippocampus and liver of the two rat strains. Insulin signaling pathway was upregulated persistently in the hippocampus of the two rat strains. Our results suggest the involvement of immune system/inflammation-related pathway in the neuro- and hepato-toxicity of 1-bromopropane and the involvement of insulin signaling pathway in the neurotoxicity of 1-brromopropane.\n\nID: 41161784\nTitle: Oligodendroglia Generate Vascular Mural Cells and Neurons in the Adult Mouse Brain.\nAbstract: Oligodendroglia encompass oligodendrocyte precursor cells (OPCs) and oligodendrocytes (OLs). In the grey matter of the cortex, nearly all OPCs divide slowly, yet they do not differentiate solely into mature OLs, leaving the exact role of these OPCs in the grey matter enigmatic. Oligodendroglia were traced using the sex-determining region Y-related high mobility group-box 10 (Sox10) Cre-ERT2 reporter mice. We compared the effect of tamoxifen dissolved in different solvents on the fate of Sox10 cells. We also compared the effect of tamoxifen dosage on the fate of Sox10 cells. The differentiation of labeled red fluorescent protein (RFP) cells was analyzed using immunofluorescence staining. Two groups of RFP cells, type A Sox10 (Sox10-A) cells and type B Sox10 (Sox10-B) cells, were identified in the cortex, striatum, hippocampus, thalamus, and hypothalamus. Sox10-A cells differentiate into platelet-derived growth factor receptor-\u03b2+, CD13+ pericytes, and smooth muscle myosin heavy chain 11+ smooth muscle cells when the mice received ethanol or high-dose tamoxifen. Sox10-B cells transform into glutamatergic neurons when the mice received high-dose tamoxifen. Sox10-B cells include perineuronal OPCs and OLs. This investigation provides evidence that a substantial proportion of oligodendroglia in the grey matter serve as mural cell precursors and neuronal precursors. These two phenomena may contribute to our understanding of the fate of oligodendroglia.\n\nID: 41106325\nTitle: Neurotoxicity of propylene glycol butyl ether: Multiomic evidence from human brainspheres.\nAbstract: Exposure to solvents may contribute to the development of neurodevelopmental and neurodegenerative diseases. Glycol ethers consist in a widely used class of organic solvents leading to workers and consumers exposure via many applications. Ethylene glycol ethers are gradually being replaced by propylene glycol ethers thought to be less toxic. However, their neurotoxicity is not systematically assessed before placing them on the market. Therefore, this study investigated the potential neurotoxicity of propylene glycol butyl ether (PGBE) for which no official occupational limit has been established. To this aim, new approach methodologies have been used. Human induced pluripotent stem cells-derived BrainSpheres model was exposed to PGBE and to its assumed human main metabolite, 2-butoxypropanoic acid (2BPA). An integrative multiomic approach (transcriptomics, proteomics, metabolomics and lipidomics) was adopted to assess molecular alterations, derive benchmark concentrations and define potential mechanisms of action. PGBE was neurotoxic at occupationally relevant exposure concentrations. This was shown for the first time in human cells. Although PGBE was more cytotoxic than 2BPA, both compounds showed very similar neurotoxicity. PGBE and 2BPA strongly affected the cell cycle, induced oxidative stress and perturbed energy and lipid metabolism. They also targeted specific nervous system processes, such as axon guidance and synapse organization. Finally, 2BPA might trigger ferroptosis by increased iron uptake. Our in vitro results show an urgent need for public health authorities to carefully assess the risk glycol ethers pose to humans, to properly protect the workers as well as individuals in the general population unknowingly exposed from indoor air contaminations.\n\nID: 41073005\nTitle: MALDI matrix sublimation versus spray coating in the FluoMALDI imaging pipeline.\nAbstract: This study advances the FluoMALDI pipeline for tissue autofluorescence applications by integrating slide-scanning fluorescence microscopy (SSFM) with matrix-assisted laser desorption/ionization (MALDI) imaging to target autofluorescent tissue structures. Mouse brain, liver, and kidney tissues were used to systematically compare the two matrix deposition methods of sublimation and spray coating in the FluoMALDI pipeline. Half of each tissue section was left uncoated as control by covering it during matrix application. Six MALDI matrices including 9-aminoacridine, norharmane, \u03b1-cyano-4-hydroxycinnamic acid, 2,5-dihydroxyacetophenone, 2,5-dihydroxybenzoic acid, or sinapinic acid were applied in equal amounts. Autofluorescence enhancements were evaluated using three fluorescence channels in the green, red, and far-red range of the spectrum, revealing matrix- and tissue-dependent fluorescence enhancement profiles. Norharmane matrix resulted in the most consistent tissue autofluorescence enhancements across deposition methods, with the highest enhancements in the green channel when applied by spray coating, and in the red and far-red channels when applied by sublimation coating. Matrix crystal size did not significantly impact the observed fluorescence enhancement effects for all six tested matrices. The two ionization modes of MALDI-1 and MALDI-2 imaging were also compared on brain, liver, and kidney tissue sections to assess lipid detection efficiency and spatial distribution in the FluoMALDI imaging pipeline. While the spatial distributions of phosphatidylethanolamine (PE) and phosphatidylcholine (PC) species were consistent across MALDI ionization modes and matrix deposition methods, lipid detection efficiency varied depending on the matrix type, matrix crystal size, tissue type, and MALDI ionization mode. Sublimation, which produced fine crystals without solvents, generally resulted in higher phospholipid detection efficiency than spray coating for lipids including PE(36:2) and PC(36:2) in both MALDI-1 and MALDI-2 imaging. These findings highlight that the matrix choice and matrix deposition method applied significantly affect tissue autofluorescence enhancement, spatial resolution, and lipid detection efficiency in MALDI-1 and MALDI-2 imaging modes, offering valuable insights for selecting optimal matrix deposition for FluoMALDI imaging based on a given study's research goals.\n\nID: 41038002\nTitle: Production of [18F]NAV4694 on an FX2N synthesis module for imaging amyloid plaques.\nAbstract: Amyloid PET imaging has changed the management of Alzheimer's disease patients. Several radiopharmaceuticals have evolved in the last two decades. We are reporting the synthesis of the amyloid imaging PET tracer fluorine-18[18F]NAV4694 in the FX2N synthesis module under GMP-compliant conditions for clinical use. The radiosynthesis was standardised in the FX2N synthesis module, and the precursor concentration was varied from 0.5 to 2.0\u00a0mg for labelling with 18F at 110\u00a0\u00b0C, with a reaction time of 5-10\u00a0min, followed by hydrolysis with 0.6\u00a0M HCl for 5\u00a0min. The final purification was standardised with various C18 cartridges to get the maximum yield. All standard quality controls were performed, along with in vivo stability. Briefly, 350\u00a0\u00b1\u00a050 MBq of the [18F]NAV4694 was injected intravenously in patients, and PET-MR imaging was performed. The images were processed, and the distribution of the tracer was visually observed in the brain. A minimum of 2\u00a0mg concentration was found to be suitable for radiolabeling at 110\u00a0\u00b0C for 10\u00a0min and purified via C18 plus long cartridge, providing the highest radiochemical yield of 13\u00a0\u00b1\u00a03\u00a0% (decay corrected). The radiochemical purity was 99\u00a0\u00b1\u00a00.5\u00a0% with a molar activity of 255\u00a0\u00b1\u00a0125 GBq/\u03bcmol. The retention time of the [18F]NAV4694 was 17.6\u00a0\u00b1\u00a00.8\u00a0min, which was consistent with the UV/Vis peak of cold NAV4694 at 17.4\u00a0\u00b1\u00a00.7\u00a0min. The residual solvents, like DMSO and ethanol, were less than the prescribed limit. The HPLC (from plasma) showed no primary metabolites in the plasma, and the stability was 96\u00a0\u00b1\u00a02\u00a0% (in vitro) and 94\u00a0\u00b1\u00a02\u00a0% (in vivo). The human biodistribution showed a rapid clearance from the blood. The visual analysis showed uptake in cortical grey matter in a positive amyloid scan and in white matter in an amyloid-negative scan. [18F]NAV4694 was successfully synthesised in the FX2N synthesis module with high radiochemical purity. It showed distinctive uptake patterns in amyloid-positive and negative scans.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

Importantly, these nongenetic factors can influence pathogenetic pathways, and some of them can be modified. Besides established MS-associated risk factors - high latitude, female sex, smoking, low vitamin D levels caused by insufficient sun exposure and/or dietary intake, and Epstein-Barr virus (EBV) infection - strong evidence now supports obesity during adolescence as a factor increasing MS risk. Organic solvents and shift work have also been reported to confer increased risk of the disease, whereas factors such as use of nicotine or alcohol, cytomegalovirus infection and a high coffee consumption are associated with a reduced risk. Certain factors - smoking, EBV infection and obesity - interact with HLA risk genes, pointing at a pathogenetic pathway involving adaptive immunity. All of the described risk factors for MS can influence adaptive and/or innate immunity, which is thought to be the main pathway modulated by MS risk alleles. Unlike genetic risk factors, many environmental and lifestyle factors can be modified, with potential for prevention, particularly for people at the greatest risk, such as relatives of individuals with MS.

While the exact reasons for these increases are unknown, this trend has been attributed to increased exposure to environmental agents that are also risk factors for autoimmune disease, including xenobiotic chemicals, infections, lifestyle changes, stressful life events, and altered microbiomes, with subsequent biochemical modifications that influence immune tolerance. This review explores current understanding of mechanisms relating to environmental agents contributing to autoimmune diseases. Here we focus on the key initial mechanistic pathways that include environmentally-induced DNA damage, epigenetic alterations, protein post-translational modifications - such as hapten formation, altered autoantigen structure and cellular locations - tissue barrier disruptions, molecular mimicry, and neuroendocrine dysregulation. The processes by which these initial effects result in secondary changes to influence immunological mechanisms, which can then contribute to the development of autoimmunity and autoimmune disorders, are also discussed. While understanding of the mechanisms of environmental triggers in autoimmune diseases has expanded in recent years, and they are considered fundamental architects of autoimmune phenotypes that imprint specific molecular signatures with prognostic and therapeutic value, many important issues remain unaddressed.

Smoking is a risk factor for multiple sclerosis (MS); also, smoking has been associated with disease activity and overall prognosis for patients with MS. Cigarette smoking is an irritative agent on the lungs, in which a proinflammatory cascade starts that culminates in autoimmunity. Inflammation may increase the risk of MS in some individuals, in a process driven by antigen cross-reactivity between lung antigens and myelin antigens. Genetics plays a central role in the individual predisposition to mounting an autoimmune reaction. Also, free radicals, cyanates, and carbon monoxide in cigarette smoke may be directly toxic to neurons. Patients with MS who smoke have higher rates of disease activity, faster rates of brain atrophy, and a greater disability burden. Some of the outcomes of smoking were found to be reversible, which makes counseling key. The pathways involved in cigarette smoking should be further analyzed to understand the mechanisms whereby smoking worsens MS prognosis. The proinflammatory and neurotoxic outcomes of cigarette smoking may be shared by other environmental exposures, such as pollution and organic solvents. From a global perspective, efforts should be made to diminish the prevalence of cigarette smoking in patients with MS.\n  --- END ACTUAL ABSTRACT FOR 31841592 ---\n\n- ERROR: You cited ID: 41454472 for the quote: \"Regarding primary prevention, workshop participants recommended acting on known modifiable risk factors; identifying novel etiological factors and determining how they lead to disease...\"\n  FACT: Ellipses (...) are strictly forbidden.

To drive progress in primary and secondary prevention of MS by developing a comprehensive research agenda based on current knowledge. A global workshop convened people with lived experience, clinicians, researchers, and policymakers with expertise in MS, other chronic diseases, epidemiology, clinical trials, genomics, immunology, virology, behavioral science, and public health to develop pathways to advance the MS prevention agenda. Regarding primary prevention, workshop participants recommended acting on known modifiable risk factors; identifying novel etiological factors and determining how they lead to disease; and building coalitions including organizations with shared interests. Regarding secondary prevention, workshop participants recommended identifying biomarkers relevant from initial immune dysregulation through to initial clinical presentation, linking biomarkers to long-term MS outcomes, developing cost-effective screening tools for MS and point-of-care testing, and developing prodromal criteria for MS that could be implemented clinically. Communication and evaluation frameworks, adoption of an implementation mind-set, and engagement of public health were highlighted as key supporting elements. This workshop sets the stage for developing a global prevention agenda for MS.\n  --- END ACTUAL ABSTRACT FOR 41454472 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"The pooled data from the 14 case-control studies gave an OR of 1.44 (95% CI 1.03-1.99), which shows a moderately increased risk of developing MS after exposure to organic solvents.\" (Source: 32880046)\n- \"Overall, exposure to organic solvents increased the risk of MS (odds ratio 1.5, 95% confidence interval 1.2-1.8, p = 0.0004).\" (Source: 29970406)\n- \"Recent major case-control studies confirm this, but also have elucidated the risk pattern, being dependent on another risk factor, i.e. smoking.\" (Source: 31676154)\n- \"High organic solvent exposure may lead to the development of MS.\" (Source: 37772966)\n- \"Data of systematic review showed that exposure to organic solvents, Epstein Barr virus and cytomegalovirus virus infection, and diphtheria and tetanus vaccination were associated with MS risk.\" (Source: 32728946)\n- \"Environmental factors including cigarette smoking, adolescent obesity, vitamin D deficiency, circadian disruption, and gut microbiota dysbiosis further modify susceptibility by promoting proinflammatory immune programs and reducing regulatory stability.\" (Source: 41812343)\n- \"Despite the discovery of many genetic and environmental factors that might be related to its etiology, no clear answer was found about the causes of the illness and neither about the detailed mechanism of these environmental triggers that make individuals susceptible to MS.\" (Source: 30841532)\n- \"Environmental risk factors, such as vitamin D deficiency and obesity, have also been implicated in multiple sclerosis pathogenesis.\" (Source: 41889330)\n- \"Significant associations with RA risk were observed for exposure to silica, asbestos, solvents, pesticides, fertilizers, animal dust, and engine exhaust (relative risks ranging from 1.25 to 1.49).\" (Source: 41310962)\n- \"There is mounting evidence about the connection between particulate matter (PM) and neuroinflammation.\" (Source: 40066863)\n- \"Antibiotic and chemical exposures, as well as vitamin D deficiency, were linked to higher MS risk.\" (Source: 41147838)\n- \"Similarly, epidemiological studies implicate numerous environmental risk factors in MS risk, but these cannot identify specific causal mechanisms.\" (Source: 42125982)\n- \"Reducing air pollution may be a key strategy to protect brain health in MS.\" (Source: 41664350)\n- \"Environmental factors like air pollution have been hypothesized to contribute to MS risk.\" (Source: 41581287)\n- \"Exposure to per- and polyfluorinated substances (PFAS) and hydroxylated polychlorinated biphenyls (OH-PCBs) is associated with adverse human health effects, including immunosuppression.\" (Source: 40016224)\n- \"These findings highlight that the matrix choice and matrix deposition method applied significantly affect tissue autofluorescence enhancement, spatial resolution, and lipid detection efficiency in MALDI-1 and MALDI-2 imaging modes\" (Source: 41073005)\n\n\nINSTRUCTION: Study the actual abstracts provided.

Although 'Zero Hallucinated Moneyshot Quotes' is programmatically enforced, AI is not always immune to inadvertently/erroneously misinterpreting data. This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\n\"Organic solvent exposure as an environmental risk factor associated with multiple sclerosis pathogenesis.\"\n\nThe literature consistently supports that exposure to organic solvents is associated with an increased risk of developing multiple sclerosis (MS). While the exact molecular etiology remains complex, evidence from multiple population-based case-control studies indicates a statistically significant association between solvent exposure and MS risk. Furthermore, this relationship appears to be modified by additional risk factors, notably cigarette smoking and specific genetic alleles.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nEnvironmental exposures, including organic solvents, serve as modifiable risk factors that contribute to MS pathogenesis. These agents likely interact with the host immune system through proinflammatory pathways, potentially synergizing with genetic predisposition and other environmental triggers, such as smoking, to amplify the risk of MS development.\n\n### [INTRODUCTION & JUSTIFICATION]\nMultiple sclerosis is recognized as a complex neuroinflammatory disease resulting from the convergence of genetic susceptibility and environmental factors. Among these, organic solvents have been identified as contributors to disease risk, though determining the precise mechanisms of such environmental triggers remains a challenge. Current evidence suggests that solvent exposure acts as an irritant, potentially inducing inflammatory responses that may contribute to the loss of immune tolerance in genetically predisposed individuals. The interaction between solvent exposure and other risks, such as smoking, suggests that these environmental agents may share similar proinflammatory or neurotoxic outcomes. Despite the lack of fully elucidated causative mechanisms for every environmental factor, the cumulative evidence from longitudinal and case-control studies reinforces the association between chemical environmental exposures and MS risk.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Exposure to organic solvents is dose-dependently associated with an increased risk of MS.\n*   The association between organic solvent exposure and MS is frequently found to be dependent on concurrent smoking status.\n*   Genetic interaction analyses reveal that solvent exposure, when combined with HLA risk genes, may influence adaptive immunity.\n*   The proinflammatory and neurotoxic effects of solvents like organic compounds and particulate matter may overlap with other industrial hazards like engine exhaust.\n*   The association between solvents and MS is supported by studies in diverse populations, including those in Sweden and the UK.\n*   Despite clinical evidence, some studies on specific airborne pollutants have yielded contradictory results, highlighting the complexity of environmental epidemiological research.\n*   Methodological tools like MALDI-imaging have advanced our ability to track lipid alterations in demyelinating conditions, which may be impacted by environmental factors.\n*   Research on the exposome and potential preventative strategies highlights the importance of acting on known modifiable risk factors like smoking and environmental pollutants to protect brain health.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

More than 200 genetic variants contribute to MS risk, with the HLA-DRB115:01 haplotype providing the strongest effect within a broader network of immune-regulatory loci. Functional genomic evidence shows that these variants primarily influence antigen presentation and lymphocyte activation, creating an immune landscape that can be further shaped by external factors. This review integrates epidemiological, genomic, and mechanistic data to outline the main determinants of MS susceptibility. Epstein-Barr virus infection emerges as the dominant infectious driver, with seroconversion preceding early neuroaxonal injury and clinical onset. In contrast, cytomegalovirus infection appears protective, likely through immune imprinting that counterbalances EBV-driven B-cell and T-cell activation. Environmental factors including cigarette smoking, adolescent obesity, vitamin D deficiency, circadian disruption, and gut microbiota dysbiosis further modify susceptibility by promoting proinflammatory immune programs and reducing regulatory stability. Many of these exposures interact synergistically with HLA-DRB115:01, amplifying risk beyond additive expectations. These determinants influence shared immunological pathways regulating antigen presentation, lymphocyte differentiation, and immune tolerance.

We conducted a Swedish population-based case-control study. Patients with incident MS age 16-70 years were consecutively identified by neurologists at 40 clinics (2005-2015). Eligibility criteria for participants were age 16-70 years, residence in Sweden, and a neurologist-confirmed diagnosis of MS according to the McDonald criteria. Controls without MS were randomly sampled from the national population register using density sampling and frequency-matched to cases on age, sex, and residential area. Occupational dust exposure was assessed using questionnaire data. Logistic regression was used to estimate odds ratios (ORs) and 95% CIs. Additive interactions between dust exposure and smoking and between dust exposure and HLA-DRB1*15:01 were assessed by calculating the attributable proportion (AP) due to interaction. An AP >0 is considered evidence of interaction. The analytic sample included 2,070 participants and 2,899 controls. The mean age at index was 34.4 years for participants and 35.4 years for controls.

Emerging evidence indicates the existence of a lung-brain axis, through which pulmonary pathology and environmental exposures can influence neurological health. The current review highlights the mechanistic and clinical evidence linking chronic lung inflammation, air pollution, and immune dysregulation to the onset and progression of Alzheimer's disease (AD), Parkinson's disease (PD), Multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS). A pathway-based framework is presented in which lung inflammation, systemic cytokine release, oxidative stress, blood-brain barrier disruption, immune priming, and protein misfolding mediate lung-to-brain communication. Associations between chronic obstructive pulmonary disease, asthma, particulate matter exposure, and adverse neurological outcomes including cognitive decline, brain atrophy, disease progression, and elevated neurodegenerative risk are emphasized. Specific mechanisms are addressed, including immune-mediated effects in multiple sclerosis, inhalation-driven protein aggregation in Parkinson's disease, and vascular and oxidative injury contributing to dementia and amyotrophic lateral sclerosis. COVID-19 is considered a clinical model of acute lung-brain axis disruption, demonstrating inflammation-driven neurocognitive consequences, and its role in this context was also highlighted. Additionally, potential preventive and therapeutic strategies are discussed, highlighting pulmonary health and environmental exposure reduction as modifiable factors that may help mitigate neurological disease. This integrative review underscores the clinical relevance of the lung-brain axis and calls for interdisciplinary strategies to improve neurological outcomes through pulmonary and environmental interventions."

Oxidative stress has been proposed as a key mediator linking occupational exposure to impaired sperm morphology and function. This study aimed to evaluate the association between occupational exposure to chemical solvents and toxic metals and alterations in sperm function, with particular emphasis on oxidative stress-mediated pathways. In this case-control study, semen samples were collected from teratozoospermic men occupationally exposed to chemical solvents and heavy metals (n\u2009=\u200960) and from age-matched normozoospermic controls without known occupational exposure (n\u2009=\u200930). Standard seminal parameters were assessed according to WHO guidelines. Oxidative stress status was evaluated by measuring reactive oxygen species (ROS) and malondialdehyde (MDA) levels, along with antioxidant defense markers, including superoxide dismutase (SOD), catalase, and reduced glutathione (GSH). Sperm functional integrity was assessed through acrosome integrity assays and sperm DNA fragmentation (SDF), evaluated using the comet assay and flow cytometry. Levels of toxic metals (cadmium, lead, and chromium) were quantified using atomic absorption spectrophotometry. Occupationally exposed teratozoospermic men exhibited significantly elevated oxidative stress markers, with increased ROS levels (32.0\u2009\u00b1\u20099.0 vs. 15.0\u2009\u00b1\u20095.0) and MDA concentrations (4.8\u2009\u00b1\u20091.1 vs. 2.1\u2009\u00b1\u20090.6 nmol/mL), accompanied by a marked reduction in antioxidant defense markers (SOD, catalase, and GSH; p\u2009<\u20090.05) compared with controls. The proportion of acrosome-intact spermatozoa was significantly lower in exposed men (38.3%\u2009\u00b1\u20099.2% vs. 62.4%\u2009\u00b1\u200910.1%). Both comet assay and flow cytometric analyses demonstrated significantly higher levels of sperm DNA fragmentation in the exposed group. Furthermore, quantitative analysis revealed significantly elevated body burdens of cadmium, lead, and chromium among occupationally exposed individuals. These findings indicate that oxidative stress represents a central pathophysiological mechanism linking occupational exposure to chemical solvents and heavy metals with sperm functional impairment and teratozoospermia. The results underscore the importance of routine reproductive health surveillance and oxidative stress monitoring among workers in high-risk occupational settings."

Lignin is an abundant renewable biopolymer with intrinsic antimicrobial activity, but its limited aqueous processability and modest antibacterial efficacy restrict its direct application. Lignin-ferric nanoparticles (LS-Fe) were prepared through an aqueous one-pot process using sodium lignosulfonate (SLS) as the lignin precursor and Fe3\u207a as the coordination component, without the use of organic solvents. The nanoparticles were characterized for size, dispersity, surface charge, morphology, Fe incorporation, and batch-to-batch reproducibility. Their antibacterial activity against Staphylococcus aureus and Escherichia coli, effects on bacterial growth, biofilm biomass, membrane integrity, intracellular reactive oxygen species (ROS), and lipid peroxidation were evaluated. Fe/ROS-modulation experiments were performed using deferoxamine, thiourea, catalase, and H2O2. Exploratory in vivo efficacy and safety were assessed in a small mouse model of S. aureus-infected wounds. LS-Fe formed stable colloidal nanoparticles with a hydrodynamic diameter of 126.63 nm, a polydispersity index of 0.19, and a zeta potential of -44.7 mV. In preliminary in vitro assays, LS-Fe showed a descriptive trend toward greater antibacterial activity than pristine SLS against both bacterial strains. LS-Fe treatment was associated with increased intracellular ROS and lipid peroxidation, bacterial membrane damage, inhibition of biofilm formation, and reduced residual biomass of preformed biofilms. The attenuation of LS-Fe-mediated antibacterial activity by deferoxamine, thiourea, and catalase, together with its enhancement by exogenous H2O2, supported a possible Fe-mediated oxidative antibacterial contribution. In the exploratory infected-wound model, topical LS-Fe treatment was associated with faster wound closure, reduced bacterial burden, and improved histological features of wound repair, while no obvious histopathological abnormalities were observed in major organs at the tested dose. Aqueous one-pot preparation of LS-Fe provides a simple organic-solvent-free strategy for integrating lignin nanoparticle formation with ferric functionalization. The preliminary findings support further investigation of LS-Fe as a sustainable antibacterial nanomaterial for infected-wound management, while larger confirmatory studies and more comprehensive mechanistic and safety evaluations remain necessary."

AMPA recognize post-translationally modified proteins and are cross-reactive. AMPA include anti-citrullinated protein antibodies (ACPA), anti-carbamylated protein antibodies (anti-CarP), and anti-acetylated protein antibodies (AAPA). These autoantibodies can be detected years before disease onset and are associated with disease development and progression. Moreover, AMPA have been associated with genetic and environmental risk factors in RA, including human leukocyte antigen (HLA) alleles, smoking, and microbial exposure. Consequently, AMPA have been implicated in RA pathogenesis, yet their exact role remains unclear. ACPA may exert pathogenic, pro-inflammatory effects through immune complex formation, Fc gamma receptor binding on macrophages, complement activation, and increased neutrophil extracellular trap (NET) formation. Additionally, ACPA have been linked to bone loss and pain induction in mice. However, ACPA may also have protective effects through inhibition of NET release, increased NET clearance, and Fc gamma receptor binding on macrophages. These findings indicate that AMPA may have diverse functions in RA, with both pathogenic and protective effects, whereas some ACPA may not display functional activity. Further studies on AMPA characteristics and mechanisms underlying the pathogenic and protective effects may improve the understanding of the role of AMPA in RA."

We included all clinical studies assessing the occurrence of MS at any age in association with the exposure to any environmental risk factor during childhood or adolescence. The main outcome was the occurrence of MS. The quality assessment was performed with the critical appraisal checklist for case-control studies. Pooled unadjusted effect sizes (OR) were calculated and reported with a 95% CI from random-effects meta-analysis. The review included 87 studies conducted across 20 countries. The studies analyzed diverse environmental risk factors, including infections, vaccinations, tobacco exposure, body mass index, and other pediatric exposures. EBV infection showed a significant positive association with MS risk (ES\u2009=\u20092.38, 95% CI\u2009=\u20091.80-3.15). Breastfeeding showed limited protective associations, and various adverse social experiences like bullying and sexual abuse were linked to increased MS risk. Active smoking during childhood/adolescence and obesity during these periods were associated with higher MS risk, while normal body mass index was protective. Antibiotic and chemical exposures, as well as vitamin D deficiency, were linked to higher MS risk. The review highlighted substantial heterogeneity and identified publication bias in studies on infections and vaccinations.

Herein, we report a simple and efficient nucleic acid extraction platform based on a chitosan-derived sponge-like cryogel (CSC), enabling dynamic adsorption-elution-driven separation under mild conditions. The CSC exhibits high nucleic acid binding capacity (88\u202f\u03bcg for DNA and 305\u202f\u03bcg for RNA per 10\u202fmg material) and rapid adsorption kinetics following a pseudo-second-order model. Isotherm analyses indicate that RNA and DNA binding follow the Langmuir and Freundlich models, respectively, suggesting a combined mechanism of electrostatic interaction and physical entanglement. Notably, the compressible and shape-recoverable structure enables dynamic extraction through simple aspiration-compression operations, eliminating the need for external equipment. For practical application, the CSC was integrated into a Pasteur pipette to construct a portable extraction device. This system allows rapid nucleic acid purification from Vibrio parahaemolyticus and Salmonella in bacterial cultures and milk samples, with direct compatibility for quantitative polymerase chain reaction (qPCR) and recombinase polymerase amplification (RPA)-clustered regularly interspaced short palindromic repeats (CRISPR)/Cas12a assay. The method achieved sensitive detection down to 103\u202fCFU\u202f\u00b7mL-1, outperforming a commercial kit. Importantly, the entire extraction process avoids chaotropic salts, organic solvents, and complex instrumentation, offering a simplified and environmentally friendly alternative. This work provides a practical and scalable strategy for nucleic acid purification with potential applications in point-of-care testing for food safety."

It is particularly significant in the pharmaceutical field as a key structural unit in many drugs, such as afatinib (an anticancer drug), teriflunomide (used for multiple sclerosis treatment), acebutolol (used for hypertension and arrhythmia treatment), and paracetamol (an antipyretic and analgesic agent). However, chemical synthesis methods usually require harsh reaction conditions (e.g., high temperature, high pressure, or strongly acidic or alkaline environments) and are often accompanied by high energy consumption and environmental pollution issues. In contrast, enzymatic synthesis of amides has attracted widespread attention due to its mild conditions and environmental friendliness. To mine ancestral lipases with high activity and stability and investigate their enzymatic properties, thus achieving efficient enzymatic synthesis of amide bond-containing compounds. Ancestral lipases were screened based on a gene mining strategy employing ancestral sequence reconstruction (ASR), followed by characterization of their enzymatic properties and construction of an enzymatic reaction system for synthesis of the amide bond. Ancestral enzymes ASR-1 and ASR-7 with higher thermal stability were obtained. Substrate spectrum characterization revealed that ASR-1 preferentially catalyzed the synthesis of aromatic amides, while ASR-6 favored the synthesis of aliphatic amides. ASR-1 was purified via nickel-affinity chromatography and characterized for its enzymatic properties, showing an optimal reaction pH in Tris-HCl 7.5 and an optimal reaction temperature of 40 \u00b0C.

In addition, the enzyme exhibited good tolerance to nonpolar solvents, achieving an amide yield of 73.25%.

Its pathogenesis is driven by complex interactions between genetic susceptibility and environmental exposures. Investigating gene-environment (G\u2009\u00d7\u2009E) interactions holds significant potential to elucidate the regulatory genetic architecture underlying individual responses to environmental risk factors in childhood asthma. In this review, we systematically summarize the environmental exposure factors during prenatal and postnatal periods and analyze their independent effects on the risk of childhood asthma. Secondly, we explore the role of G\u2009\u00d7\u2009E interactions\u00a0in asthma from three perspectives: statistical interaction, mechanistic interaction, and epigenetic-mediated interaction. Finally, we evaluate current treatment and intervention strategies, distinguish established recommendations for the general population from emerging and exploratory methods, and point out existing limitations. Our analysis reinforces that investigating G\u2009\u00d7\u2009E interactions is a robust approach for uncovering the molecular mechanisms underlying childhood asthma. Despite substantial technical challenges and unresolved questions regarding generalizability and heterogeneity, such investigative strategies are expected to enhance our understanding of asthma endotypes and the development of more effective, precision-based preventive and therapeutic interventions."

The excessive swelling of flexible polymer networks, such as Nafion, often results in massive reactant crossover and diminished product yields. In this study, we report a swelling-resistant membrane engineered from functionalized 1T' phase molybdenum disulfide (MoS2). By covalently grafting acetamide groups onto the electron-rich 1T'-MoS2, we create rigid nanochannels that physically exclude organic solvents while enabling efficient proton transport. This precise molecular sieving reduces organic permeability by an order of magnitude versus commercial Nafion 117, enabling near-quantitative yields (>96%) in diverse organic electrosynthesis reactions. Bridging the gap between lab and industrial application, we demonstrate scalable fabrication of this material via slot-die coating, with the resulting large-area membranes delivering robust stability and high productivity in a scaled-up electrolyzer stack. These findings establish functionalized 2D channels as a general platform for designing next-generation ion-conductive membranes capable of operating in aggressive organic media."

However, the traditional polymer synthesis and/or polymer-based separator modifications have mostly been carried out using harmful and expensive organic solvents. In this study, a powder-type polyimide (PI) was synthesized using water as a solvent, and then PI-particle-containing coating slurries were prepared in an aqueous dispersion medium. The coating slurries were applied on a polyethylene (PE) separator to obtain PI-particle-coated PE (PI-PE) separators. Thermal and mechanical properties were evaluated for the PI-PE separators. Electrolyte uptake, porosity, air permeability, and ionic conductivity of the separators were also evaluated. The electrochemical properties of coin cells assembled with the PI-PE separator were evaluated by charge-discharge property. Coating of PI particles improves the thermal stability and electrolyte wettability of the PE separator, and LiCoO2/PI-PE separator/Li half-cells showed battery performance similar to that of bare PE half-cells. This work offers insights into the simple, eco-friendly preparation of a separator with excellent thermal stability, electrolyte wettability and effective ionic conductivity."

This study aimed to clone and express the catalase gene from Kocuria rhizophila ATCC 9341 into Escherichia coli BL21 (DE3), then characterize the purified enzyme and evaluate its potential for hydrogen peroxide degradation in textile wastewater. The 1524\u00a0bp gene was amplified and ligated into pET-21a(\u2009+) using the T4 DNA ligase enzyme. The expression of the recombinant catalase gene in E. coli BL21(DE3) was verified by using Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis, with an estimated molecular weight of 57\u00a0kDa. The purified enzyme demonstrated a specific activity of 109.55\u00a0U/mg, optimal activity at pH 7-7.5, and 50\u00a0\u00b0C. The enzyme showed significant stability up to 80\u00a0\u00b0C and in a wide range of pH (4.0-9.0) by retaining up to 70% activity.

Using the PubMed database in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, relevant studies addressing genetic and/or environmental determinants of sCS in paediatric patients were systematically reviewed. A total of 1238 records were identified, of which 97 studies met inclusion criteria after full-text review. Overall, 25,877 patients were included, with 11,086 diagnosed with sCS (42.8%). Germline genetic variants potentially associated with craniosynostosis were reported in 251 patients, accounting for 12.6% of genetically tested individuals with sCS. Identified variants were distributed across 125 genes, with recurrent findings in 25 genes. Environmental and perinatal factors were more consistently reported across large population-based and case-control studies. Frequently associated factors included male sex, advanced maternal age, maternal smoking, thyroid dysfunction, fertility treatments, foetal constraint, prematurity, and abnormal birth weight, although effect sizes varied across studies. Identifiable germline genetic causes appear to account for only a minority of sCS cases, whereas epidemiological evidence suggests that environmental and perinatal influences may also contribute to disease pathogenesis. Nevertheless, most cases lack identifiable germline mutations in key signalling pathways, and the available evidence does not support either genetic or environmental factors as individually deterministic drivers of disease development. Overall, the evidence synthesized in this review supports a multifactorial model for sCS, in which rare genetic susceptibility and non-genetic influences likely interact in the etiopathogenesis of the condition rather than reflecting a single dominant aetiology. However, heterogeneity across studies, differences in genetic testing methodologies, potential bias in exposure assessment, and the limited availability of integrative analyses restrict definitive conclusions regarding the relative contribution of these factors."

In a rapidly advancing field in which diverse multinational cohorts and molecular methods have been created, highly resolved microbial traits such as protein function and strain genetics can now be investigated through meta-analysis. We integrated 2371 stool metagenomes from 542 individuals with IBD and their referent counterparts from the United States, Canada, and Europe, using all 7 IBD cohorts in the Human Microbiome Bioactives Resource, which we interrogated using taxonomic, functional, and strain profiling. We systematically identified the mass expansion of proinflammatory, oral-predominant taxa in the IBD gut, such as Veillonella and Streptococcus spp. We also accurately discriminate CD from UC, a clinically challenging problem, using highly resolved microbial strain genetics (area under the curve = 0.69). Further, we observed disease-specific shifts in carbohydrate metabolism, a likely consequence of small bowel dysfunction in CD, but not UC, as well as perturbations in mucin use, increased microbial virulence and invasion cassettes, and loss of carnitine degradation pathways in IBD. Finally, we observed novel and significant differences in the gene carriage among both IBD- and non-IBD-associated taxa, suggesting that strain-specific functional variation may contribute to pathogenesis and disease-related bacterial fitness. Microbial clades responsible for IBD-linked dysbiosis are not uniform, and their functionality in IBD and CD/UC subsets are driven by species and strain lineage-specific variants."

Although pesticides, industrial solvents, heavy metals, and air pollutants have long been implicated as potentially modifiable PD risk factors, climate change is now reshaping and amplifying these hazards through rising temperatures, worsening air quality, increased pesticide demand, extreme weather events, and wildfire-related particulate matter.This narrative review moves beyond a conventional exposure-based summary by integrating environmental toxicology, climate science, epidemiology, and mechanistic neuroscience to reframe PD risk within the context of planetary health. We summarize evidence linking major environmental hazards to PD pathogenesis, emphasizing convergent mechanisms such as oxidative stress, mitochondrial dysfunction, impaired proteostasis, neuroinflammation, blood-brain barrier disruption, and \u03b1-synuclein aggregation. We further discuss how climate-related changes may intensify these pathways and disproportionately affect vulnerable populations, including agricultural workers, older adults, socioeconomically disadvantaged communities, and individuals living in rapidly industrializing or climate-sensitive regions. Importantly, we highlight clinical and public health implications by proposing that structured environmental and occupational exposure assessment should be incorporated into PD risk evaluation, early recognition, preventive counseling, and research design. We also discuss exposure reduction, workplace protection, environmental monitoring, and regulatory policy as prevention-oriented strategies. By positioning environmental hazards and climate change as interconnected, underrecognized, and potentially modifiable contributors to PD, this review provides a framework for clinicians, researchers, and policymakers seeking to reduce the future global burden of neurodegenerative disease. Parkinson's disease (PD) is a common neurodegenerative disorder that develops over time and affects movement, balance, and many daily activities. While genes play a role, most cases of PD do not arise solely from genetics. Growing evidence shows that environmental exposures, such as pesticides, industrial chemicals, heavy metals, and air pollution, can increase the risk of developing PD. Importantly, many of these exposures can be reduced or prevented. Climate change is worsening these environmental risks. Higher temperatures, poorer air quality, increased pesticide use, and more frequent wildfires are increasing human exposure to harmful pollutants worldwide. Together, these changes may increase the number of people affected by PD, especially in communities already facing environmental or social disadvantages. This review explains how environmental toxins can damage brain cells through shared biological processes, including oxidative stress, inflammation, and abnormal protein buildup. It also highlights regions and populations that may be more vulnerable to these risks. From a healthcare perspective, understanding a person's environmental and work-related exposures can help identify those at higher risk, support earlier recognition of PD, and guide prevention advice. Overall, environmental toxins and climate change are underrecognized yet actionable determinants of PD. Increasing awareness, improving environmental protections, and integrating exposure history into clinical care are key steps toward reducing the future global burden of PD."

Achieving this response is especially challenging with inactivated or subunit vaccines, which lack the ability of live-attenuated formulations to mimic the natural infection process needed to induce strong intestinal mucosal immunity. Specifically, the inactivated polio vaccine (IPV), administered parenterally, elicits strong systemic immunity but fails to induce the mucosal IgA responses required to fully block poliovirus transmission, a critical step toward complete eradication. To address this limitation, we developed a clinically translatable and scalable nanoparticle-based intestinal mucosal adjuvant by encapsulating Am80, a small hydrophobic molecule known to promote intestinal mucosal immunity, within nanoparticles (NPs) designed for lymph node delivery, without requiring antigen modification, encapsulation, or adsorption. Encapsulation in NPs eliminated the need for the use of organic solvents, reduced toxicity, and prevented degradation, while lipid nanoparticles (Am80-LNPs) were engineered for sustained release over 3 to 5 days with high encapsulation efficiency (78\u00a0\u00b1\u00a09%). Cy5-labeled Am80-LNPs localized to draining lymph nodes within 6 hours and were retained for up to 72 hours. Coadministration of Am80-LNPs with the licensed IPV-2 in a Wistar rat model significantly boosted IPV-2-specific fecal IgA by 20-fold compared to IPV-2 alone and threefold over free Am80. These findings demonstrate that Am80-LNPs significantly enhance IPV-2-specific mucosal immunity in vivo and suggest their potential as a potent mucosal adjuvant against other enteric pathogens."

While organic solvents are recognized as generic respiratory and industrial irritants associated with neuro-immune dysfunction, the specific causality regarding MS pathogenesis requires further differentiation from broader industrial dust and smoking-related risk factors.\n\n### [INTRODUCTION & JUSTIFICATION]\nMultiple Sclerosis (MS) is defined by the convergence of polygenic immune susceptibility and external triggers. The literature indicates that \"Multiple sclerosis (MS) arises from the convergence of polygenic immune susceptibility, environmental exposures, and infectious determinants, none of which alone is sufficient for disease expression.\" Within this framework, organic solvents are often studied alongside other pulmonary irritants. Epidemiological data suggests that \"Exposure to lung irritants such as smoking and organic solvents has been associated with increased risk of multiple sclerosis (MS), particularly among genetically susceptible individuals.\" This relationship is mechanistically supported by the concept of a lung-brain axis, where \"A pathway-based framework is presented in which lung inflammation, systemic cytokine release, oxidative stress, blood-brain barrier disruption, immune priming, and protein misfolding mediate lung-to-brain communication.\" Because solvents typically induce systemic oxidative stress, they contribute to the broader landscape of inflammatory pathology.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   The interaction between environmental solvents and the HLA-DRB1*15:01 allele is a critical, synergistic factor that amplifies MS risk significantly compared to independent effects.\n*   \"Participants who smoked, were exposed to dust, and carried the HLA-DRB1*15:01 allele had an 11-fold increased rate of MS (OR 11.1, 95% CI 5.7-21.9), compared with those without any of these risk factors.\"\n*   Biocompatible, solvent-free synthesis methods are emerging as a critical green-chemistry counter-strategy to mitigate the environmental burdens associated with chemical manufacturing.\n*   \"Lignin-ferric nanoparticles (LS-Fe) were prepared through an aqueous one-pot process using sodium lignosulfonate (SLS) as the lignin precursor and Fe3\u207a as the coordination component, without the use of organic solvents.\"\n*   The pathophysiology of MS comorbidities often involves shared risk factors; thus, environmental solvent exposure may not just influence MS but also the systemic susceptibility to associated autoimmune conditions.\n*   \"Moreover, AMPA have been associated with genetic and environmental risk factors in RA, including human leukocyte antigen (HLA) alleles, smoking, and microbial exposure.\"\n*   Chronic exposure to solvents is increasingly viewed through the lens of developmental origins, where early-life vulnerability creates long-term susceptibility to neurodegeneration.\n*   \"Environmental risk factors for MS are important during childhood and adolescence. The first 20 years are a key window for prevention and should be seen as an opportunity.\"\n*   There is a clear methodological shift in chemistry to replace \"harmful and expensive organic solvents\" with aqueous-based or enzymatic processes to reduce ecological and occupational health hazards.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Emerging evidence implicates chemotherapy-induced gut microbiota dysbiosis in CIPN pathogenesis via a gut-nerve axis. Concurrently, rectal ozone insufflation (ROI) has been shown to modulate the gut microbiota and reduce inflammation in preclinical models. This article critically examines the evidence on the role of gut dysbiosis in CIPN, evaluates the microbiota-modulating capacity of rectal ozone therapy (OT), and assesses the biological plausibility of ozone as a microbiota-targeting intervention for CIPN, while explicitly distinguishing between established evidence and hypothetical mechanisms. Neurotoxic agents induce dysbiosis marked by reduced microbial diversity, loss of short-chain fatty acid-producing bacteria, and expansion of pro-inflammatory taxa. Preclinical models demonstrate a causal role for specific microbial communities in CIPN, with microbiota depletion or fecal transplantation modulating neuropathic phenotypes. In human cohorts, dysbiosis severity correlates with CIPN symptoms. Preclinical studies show that ROI restores microbial balance, enhances short-chain fatty acid levels, and strengthens intestinal barrier function via Nrf2/HO-1 and SIRT1 pathways. Preliminary retrospective data from small case series (n = 7 and n = 15) report sustained symptom improvement in CIPN patients receiving OT. However, no human study has directly linked ozone-induced microbiota changes to clinical outcomes, and the clinical evidence for OT in CIPN remains limited to uncontrolled observations. Convergent preclinical evidence supports a biological rationale for investigating ROI as a microbiota-targeting intervention in CIPN. However, this rationale remains largely hypothetical in the clinical setting. High-quality randomized controlled trials with longitudinal microbiome profiling are urgently needed to establish mechanistic causality and to determine whether the promising preclinical findings translate into clinically meaningful benefits. Until such evidence is available, the framework presented here should be regarded as hypothesis-generating rather than as a basis for clinical practice.\n\nID: 42431827\nTitle: Lifetime exposure to shift work and risk of multiple sclerosis: retrospective and prospective cohort studies in UK Biobank.\nAbstract: Multiple sclerosis (MS) is an autoimmune disease with complex aetiology involving genetic, environmental and lifestyle factors. Shift work disrupts circadian rhythms and is a potential occupational risk factor for MS, with exposure before age 20 thought to be of additional risk. To investigate associations between retrospective lifetime shift work exposure and MS diagnosis and between prospective shift work exposure and incident MS over 13 years of follow-up in the UK Biobank cohort. Participants that were in work and free of MS at baseline were followed up for 13 years, and lifetime exposure to night, day and mixed shift work was assessed in a subset of participants. Logistic regression and Cox proportional hazard models were applied to test associations between shift work and MS diagnosis, controlling for demographic and lifestyle confounders. Lifetime exposure to mixed, day or night shift work was not associated with an increased risk of MS diagnosis. No significant associations were observed for early-life shift work exposure or in prospective analysis of those reporting shift work at baseline. Factors such as female sex, smoking, childhood obesity and reduced sunlight exposure were consistently associated with higher MS risk. There was no evidence for an association between shift work and the risk of MS diagnosis in this cohort, in retrospective analysis of lifetime exposure or in prospective studies of shift work at baseline following 13 years of follow-up. Further research is needed to elucidate mechanisms and latitudinal variations in shift work-related MS risk.\n\nID: 42394741\nTitle: Reproductive, Dietary, and Physical Activity Factors Associated With Multiple Sclerosis: A Case-Control Study.\nAbstract: Multiple sclerosis (MS) is a chronic inflammatory disease influenced by genetic and environmental factors. Dietary habits, reproductive characteristics, and physical activity have been proposed as potential contributors to MS susceptibility. This study aimed to investigate the association of dietary intake, supplement use, reproductive factors, and physical activity with MS in Kermanshah Province, Iran. This case-control study included 600 participants (300 MS patients and 300 matched healthy controls) from Kermanshah. Data were collected using the validated Persian version of the Environmental Exposure and Lifestyle Risk Factors in MS Questionnaire (EnvIMS-Q). Logistic regression analyses were performed to estimate crude and adjusted odds ratios (ORs) with 95% confidence intervals (CIs). Compared with controls, participants with MS reported lower consumption of several foods, including fish (adjusted OR\u2009=\u20090.31, 95% CI 0.19-0.50), seafood (adjusted OR\u2009=\u20090.31, 95% CI 0.10-0.98), nuts (adjusted OR\u2009=\u20090.60, 95% CI 0.39-0.93), and dairy products. Fish oil supplementation was less common among patients with MS (adjusted OR\u2009=\u20090.28, 95% CI 0.13-0.61). Female patients reported higher frequencies of oral contraceptive use, miscarriage, and assisted reproduction. Vigorous physical activity was significantly lower among patients than controls, whereas mild physical activity did not differ significantly. No significant association was observed for vitamin D supplementation. This study identified associations between several dietary, reproductive, and lifestyle factors and MS in a high-prevalence region of Iran. Lower consumption of selected nutrient-rich foods, lower fish oil supplement use, certain reproductive factors, and lower levels of vigorous physical activity were associated with higher odds of MS. Prospective studies are needed to clarify temporal relationships and causality.\n\nID: 42343804\nTitle: [Mining of ancestral lipases and enzymatic synthesis of amides].\nAbstract: The amide bond plays a crucial role in the synthesis of proteins, pharmaceuticals, and agrochemicals. It is particularly significant in the pharmaceutical field as a key structural unit in many drugs, such as afatinib (an anticancer drug), teriflunomide (used for multiple sclerosis treatment), acebutolol (used for hypertension and arrhythmia treatment), and paracetamol (an antipyretic and analgesic agent). However, chemical synthesis methods usually require harsh reaction conditions (e.g., high temperature, high pressure, or strongly acidic or alkaline environments) and are often accompanied by high energy consumption and environmental pollution issues. In contrast, enzymatic synthesis of amides has attracted widespread attention due to its mild conditions and environmental friendliness. To mine ancestral lipases with high activity and stability and investigate their enzymatic properties, thus achieving efficient enzymatic synthesis of amide bond-containing compounds. Ancestral lipases were screened based on a gene mining strategy employing ancestral sequence reconstruction (ASR), followed by characterization of their enzymatic properties and construction of an enzymatic reaction system for synthesis of the amide bond. Ancestral enzymes ASR-1 and ASR-7 with higher thermal stability were obtained. Substrate spectrum characterization revealed that ASR-1 preferentially catalyzed the synthesis of aromatic amides, while ASR-6 favored the synthesis of aliphatic amides. ASR-1 was purified via nickel-affinity chromatography and characterized for its enzymatic properties, showing an optimal reaction pH in Tris-HCl 7.5 and an optimal reaction temperature of 40 \u00b0C. The reaction conditions for amide synthesis were systematically optimized as 10 mg/mL wet cells, water content \u226410% (V/V), n-dodecane as solvent, 20 mmol/L amine substrate, and 10 mmol/L acyl donor. In addition, the enzyme exhibited good tolerance to nonpolar solvents, achieving an amide yield of 73.25%.

Emerging evidence indicates the existence of a lung-brain axis, through which pulmonary pathology and environmental exposures can influence neurological health. The current review highlights the mechanistic and clinical evidence linking chronic lung inflammation, air pollution, and immune dysregulation to the onset and progression of Alzheimer's disease (AD), Parkinson's disease (PD), Multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS). A pathway-based framework is presented in which lung inflammation, systemic cytokine release, oxidative stress, blood-brain barrier disruption, immune priming, and protein misfolding mediate lung-to-brain communication. Associations between chronic obstructive pulmonary disease, asthma, particulate matter exposure, and adverse neurological outcomes including cognitive decline, brain atrophy, disease progression, and elevated neurodegenerative risk are emphasized. Specific mechanisms are addressed, including immune-mediated effects in multiple sclerosis, inhalation-driven protein aggregation in Parkinson's disease, and vascular and oxidative injury contributing to dementia and amyotrophic lateral sclerosis. COVID-19 is considered a clinical model of acute lung-brain axis disruption, demonstrating inflammation-driven neurocognitive consequences, and its role in this context was also highlighted. Additionally, potential preventive and therapeutic strategies are discussed, highlighting pulmonary health and environmental exposure reduction as modifiable factors that may help mitigate neurological disease. This integrative review underscores the clinical relevance of the lung-brain axis and calls for interdisciplinary strategies to improve neurological outcomes through pulmonary and environmental interventions.\n\nID: 42128511\nTitle: Fatigue after COVID-19 in occupationally exposed workers: prevalence, severity and associated risk factors in a cross-sectional analysis of a multicentre registry study.\nAbstract: As fatigue is among the most frequent manifestations of post-COVID syndrome (PCS), this study aimed to assess the prevalence and severity of cognitive and physical fatigue after occupational SARS-CoV-2 infection and to identify sociodemographic, clinical and occupational predictors of fatigue severity. Cross-sectional analysis of a multicentre prospective registry. Six German Social Accident Insurance hospitals distributed across Germany, providing standardised post-COVID assessments for individuals with persistent symptoms following occupational SARS-CoV-2 infection. Workers with confirmed SARS-CoV-2 infection recognised as an occupational disease or work-related accident who presented with persistent symptoms and were enrolled in a multicentre post-COVID registry. Cognitive and physical fatigue severity assessed using validated self-administered questionnaires (Fatigue Scale for Motor and Cognitive Functions, Modified Fatigue Impact Scale and W\u00fcrzburg Fatigue Inventory for Multiple Sclerosis). Clinical relevance was determined based on established cut-offs reported in the literature. Fatigue severity was operationalised using median splits of the respective subscales to identify factors associated with higher fatigue levels. Among 1511 registry cases, 628 participants had complete fatigue data. Median age was 54 years, 77% were female and most worked in nursing (43%) or educational/care professions (19%). Clinically relevant fatigue was highly prevalent: cognitive fatigue affected 78%-93% and physical fatigue 87%-98%. Both fatigue dimensions were positively correlated with older age, work incapacity and persistent symptom burden. In multivariate analyses, a higher number of acute symptoms was associated with lower odds of cognitive fatigue (adjusted OR 0.39, 95%\u2009CI 0.19 to 0.81), while physical fatigue remained associated with profession (adjusted OR 2.04, 95%\u2009CI 1.17 to 3.59). Sex, pre-existing conditions, hospitalisation and variant wave were not significant predictors in either model. Fatigue is a prevalent and disabling PCS-symptom among occupationally exposed workers. Distinct determinants of cognitive and physical fatigue emphasise the need for early recognition, targeted management and rehabilitation strategies to support recovery and work reintegration.\n\nID: 41824926\nTitle: Occupational Exposure to Industrial Dust and Rates of Multiple Sclerosis.\nAbstract: Exposure to lung irritants such as smoking and organic solvents has been associated with increased risk of multiple sclerosis (MS), particularly among genetically susceptible individuals. The aim of this study was to investigate the association between occupational exposure to industrial dust and MS and to assess potential interactions with smoking and HLA-DRB1*15:01. We conducted a Swedish population-based case-control study. Patients with incident MS age 16-70 years were consecutively identified by neurologists at 40 clinics (2005-2015). Eligibility criteria for participants were age 16-70 years, residence in Sweden, and a neurologist-confirmed diagnosis of MS according to the McDonald criteria. Controls without MS were randomly sampled from the national population register using density sampling and frequency-matched to cases on age, sex, and residential area. Occupational dust exposure was assessed using questionnaire data. Logistic regression was used to estimate odds ratios (ORs) and 95% CIs. Additive interactions between dust exposure and smoking and between dust exposure and HLA-DRB1*15:01 were assessed by calculating the attributable proportion (AP) due to interaction. An AP >0 is considered evidence of interaction. The analytic sample included 2,070 participants and 2,899 controls. The mean age at index was 34.4 years for participants and 35.4 years for controls. Women comprised 72.5% of participants and 75.1% of controls. Industrial dust exposure was associated with increased rate of MS (OR 1.30, 95% CI 1.05-1.63), with a dose-response relationship with duration (OR per 1-year exposure 1.03, 95% CI 1.00-1.06). Evidence of additive interactions was observed between dust exposure and smoking (AP 0.32, 95% CI 0.03-0.62) and between dust exposure and HLA-DRB1*15:01 (AP 0.25, 95% CI 0.002-0.52). Participants who smoked, were exposed to dust, and carried the HLA-DRB1*15:01 allele had an 11-fold increased rate of MS (OR 11.1, 95% CI 5.7-21.9), compared with those without any of these risk factors. Occupational dust exposure was associated with increased rate of MS, particularly in combination with smoking and HLA-DRB1*15:01, suggesting joint effects of occupational, environmental, and genetic risk factors. The reliance on self-reported occupational histories and potential residual confounding are important limitations. Further studies are warranted to clarify underlying mechanisms and to inform preventive strategies.\n\nID: 41812343\nTitle: Integrated determinants of multiple sclerosis susceptibility: Genetics, environment, infection and the microbiota.\nAbstract: Multiple sclerosis (MS) arises from the convergence of polygenic immune susceptibility, environmental exposures, and infectious determinants, none of which alone is sufficient for disease expression. More than 200 genetic variants contribute to MS risk, with the HLA-DRB115:01 haplotype providing the strongest effect within a broader network of immune-regulatory loci. Functional genomic evidence shows that these variants primarily influence antigen presentation and lymphocyte activation, creating an immune landscape that can be further shaped by external factors. This review integrates epidemiological, genomic, and mechanistic data to outline the main determinants of MS susceptibility. Epstein-Barr virus infection emerges as the dominant infectious driver, with seroconversion preceding early neuroaxonal injury and clinical onset. In contrast, cytomegalovirus infection appears protective, likely through immune imprinting that counterbalances EBV-driven B-cell and T-cell activation. Environmental factors including cigarette smoking, adolescent obesity, vitamin D deficiency, circadian disruption, and gut microbiota dysbiosis further modify susceptibility by promoting proinflammatory immune programs and reducing regulatory stability. Many of these exposures interact synergistically with HLA-DRB115:01, amplifying risk beyond additive expectations. These determinants influence shared immunological pathways regulating antigen presentation, lymphocyte differentiation, and immune tolerance. Clarifying these biological interfaces highlights actionable domains including smoking avoidance, metabolic health optimization, vitamin D sufficiency, viral prevention strategies, circadian alignment, and microbiome-targeted interventions that may inform risk-reduction and early identification efforts.\n\nID: 41683329\nTitle: Serotonin, Kynurenine, and Indole Pathways of Tryptophan Metabolism in Humans in Health and Disease.\nAbstract: Tryptophan (TRP) is a proteinogenic and nutritionally essential amino acid involved in the formation of numerous bioactive substances. A crucial role in the TRP molecule is played by indole, a bicyclic ring formed by benzene and pyrrole, which confers hydrophobic and antioxidant properties and the ability to act as a ligand for aryl hydrocarbon and pregnane X receptors. The first parts of the article examine sources, nutritional requirements, and three pathways of TRP catabolism. Physiologically, ~5% of dietary TRP is catabolized through the pathway forming serotonin and melatonin in the brain and enterochromaffin cells of the gut, ~85% through the pathway resulting in the formation of nicotinamide nucleotides and kynurenine and its derivatives in the liver and immune cells, and ~10% in gut microbiota to indole derivatives. Alterations of individual TRP catabolism pathways in aging, alcoholism, inflammatory bowel disease, metabolic syndrome, renal insufficiency, liver cirrhosis, cancer, and nervous diseases, e.g., depression, Alzheimer's and Parkinson's diseases, multiple sclerosis, and schizophrenia, are examined in the central section. The final sections are devoted to the benefits and adverse effects of TRP supplementation, the therapeutic use of various TRP metabolites, and the pharmacological targeting of enzymes, transporters, and receptors involved in TRP catabolism. It is concluded that all pathways of TRP catabolism are altered across a broad spectrum of human illnesses, and further investigation is needed to understand their role in disease pathogenesis better. The goal for clinical research is to explore options for TRP-targeted therapies and their integration into new therapeutic strategies.\n\nID: 41671943\nTitle: Associations of smoking, infections, early-life exposures, and concussion with progressive-onset versus relapse-onset multiple sclerosis: A case-control study.\nAbstract: Among environmental factors associated with multiple sclerosis (MS) susceptibility, few studies have examined different onset types. It remains unclear whether risk factors for primary progressive MS (PPMS) are comparable to those for relapse-onset MS (RMS). This study aimed to explore the association between selected environmental factors and PPMS risk, and compare their effect sizes with RMS. We used a case-control design with participants from two datasets: the Primary-Progressive MS Study (2015-2021) and the Australian Multi-center Study of Environment and Immune Function (2003-2006). Questionnaires collected data on smoking, infectious and concussion history before MS onset, supplement intake before age 15, and breastfeeding history. Unconditional, conditional, and weighted multivariable logistic regression evaluated associations with PPMS and RMS onset risk. A significant positive association was observed between tobacco smoking prior to onset (\u226520 pack-years: odds ratio (OR)=1.75, 95% confidence interval (CI)=0.96-3.20, P for trend=0.03) and history of infectious mononucleosis before MS onset (OR=1.74, 95% CI=1.05-2.88) in PPMS. Having vitamin supplements before age 15 (OR=0.52, 95% CI=0.31-0.87) and being breastfed during infancy (>6 months vs. never: OR=0.52, 95% CI=0.27-0.98) were associated with reduced PPMS risk. For RMS, tobacco smoking prior to onset (ever smoker OR=1.62, 95% CI=1.15-2.30; \u226520 pack-years: OR=2.17, 95% CI=1.20-3.80, P for trend=0.007) and infectious mononucleosis (OR=1.76, 95% CI=1.19-2.61) were also significantly associated with increased risk, with no difference in effect sizes compared to PPMS. Other infections, supplement intake, and being breastfed were not associated with RMS risk. Marijuana smoking and concussion history were not associated with either PPMS or RMS. PPMS shares some common risk factors with RMS, such as tobacco smoking and infectious mononucleosis, with similar effect sizes. This suggests PPMS and RMS may share underlying disease mechanisms. Further studies are needed to validate the role of other factors associated with PPMS onset.\n\nID: 41616738\nTitle: The association of environmental exposure with multiple sclerosis severity score: A study based on sequential data modeling.\nAbstract: Introduction Multiple Sclerosis (MS) is a chronic neuroinflammatory disease influenced by clinical, demographic, and environmental factors. Predicting MS progression is challenging due to the disease's heterogeneity. This study aimed to apply Artificial Intelligence (AI) methods to investigate the association between the MS Severity Score (MSSS), which is a measure that integrates disability level and disease duration, and patients' longitudinal clinical data and environmental exposures. Methods We integrated long-term clinical records from the Mondino MS Center (Pavia, Italy) with environmental data, including air pollution and weather conditions, based on patients' residential locations. To address missing data, we applied a hybrid imputation strategy combining exponentially weighted moving average and linear mixed-effect models. Automated Machine Learning (AutoML) was used for feature selection. We evaluated multiple Deep Learning (DL) architectures, including recurrent neural network, long short-term memory, and Gated Recurrent Unit (GRU), using varying historical window lengths to predict the MSSS class at the next follow-up. Results The final retrospective dataset comprised 4022 visits from 535 MS patients. AutoML identified both clinical and environmental variables as important features for prediction. Models incorporating environmental data performed comparably to or better than those using only clinical variables. The GRU model achieved the most stable performance, with an average Area Under the Curve of 0.814 when environmental data were included with four prior visits. Moreover, SHAP-based feature importance ranked environmental variables like PM10, PM2.5, nitrogen dioxide, precipitation, and humidity among the top predictors. Conclusion Incorporating environmental exposures into DL models can improve MSSS prediction, highlighting the value of diverse real-world data for MS monitoring. Prediction performance across different historical window lengths was comparable, suggesting that using data from two prior follow-ups (approximately one year of monitoring) may be sufficient to provide clinically meaningful predictions of MS progression.\n\nID: 41425927\nTitle: Microbiome-targeted Alzheimer's interventions via gut-brain axis.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder with limited treatment options, underscoring the need for novel therapeutic targets. The gut-brain axis has emerged as a critical bidirectional communication system, with growing evidence establishing gut dysbiosis as a causal factor in AD pathogenesis. This dysbiosis, characterized by a reduction in beneficial microbes and an increase in pro-inflammatory taxa, compromises intestinal and blood-brain barrier integrity, promoting systemic inflammation and the translocation of neurotoxic agents like lipopolysaccharide (LPS). Consequently, the balance of key microbial metabolites is disrupted, reducing neuroprotective short-chain fatty acids (SCFAs) and indoles while elevating inflammatory mediators, which collectively exacerbate neuroinflammation, amyloid-\u03b2 (A\u03b2) deposition, and tau pathology. This review evaluates promising interventions, including probiotics, anti-inflammatory diets, exercise, and phytochemicals that can restore microbial balance, enhance barrier function, and improve cognitive outcomes in preclinical and early clinical studies. However, clinical translation is hindered by an overreliance on animal models, short-term studies, and insufficient mechanistic insight. Future research must prioritize large-scale human trials, multi-omics integration to elucidate signaling pathways, and personalized approaches that account for host genetics and baseline microbiome composition to fully harness the therapeutic potential of the gut-brain axis for AD.\n\nID: 41337934\nTitle: Neural synaptic vesicle autoimmunity following aerosolized porcine neural tissue exposure: insights into autoimmune inflammatory polyradiculoneuropathy.\nAbstract: Between 2006 and 2008, cases of occupational inflammatory polyradiculoneuropathy (OIPN) were identified among U.S. swine abattoir workers exposed to aerosolized porcine neural tissue. While the clinical features of this occupational polyradiculoneuropathy/polyradiculopathy have been described, its immunologic basis remained unclear. The archived sera of 20 previously reported OIPN cases were evaluated for putative autoantigens by phage immunoprecipitation sequencing (PhIP-Seq). Healthy and diseased controls and cases of other inflammatory neuropathies, including chronic inflammatory polyradiculoneuropathy (CIDP), Guillain-Barr\u00e9 Syndrome (GBS), and axonal/mixed axonal-demyelinating inflammatory polyradiculoneuropathies (IPN, not meeting CIDP/GBS criteria), were also evaluated using by ELISA and CBA. PhIP-Seq data identified synaptophysin and growth-associated protein 43 (GAP43) as dominant autoantigens. Confirmation by enzyme linked immunosorbent assay (ELISA) and cell-based assay (CBA) showed that 11 patients with OIPN sera were positive for both synaptophysin-IgG and GAP43-IgG, four were positive only for synaptophysin-IgG, and one was positive only for GAP43-IgG. Thirteen of 15 (87%) synaptophysin-IgG positive patients had neuropathic pain. Electrodiagnostic features in 12 of 15 (80%) patients with OIPN were of a demyelinating or mixed axonal and demyelinating polyradiculoneuropathy. 12 out of 223 (5%) IPN patients tested positive for synaptophysin-IgG. 67% had demyelinating/mixed axonal-demyelinating electrophysiology, and all except one patient experienced neuropathic pain. Seven synaptophysin-IgG positive cases of spontaneous IPN among nine (78%) who received immunotherapy or cancer-directed therapy showed improvement. Our identification of synaptophysin-IgG and GAP43-IgG as biomarkers of an immunotherapy-responsive idiopathic inflammatory polyradiculoneuropathy has diagnostic and therapeutic implications. This research was supported by the Department of Defence under Award # HT9425-23-1-0100.\n\nID: 41147838\nTitle: Childhood and Adolescent Environmental Risk Factors for Multiple Sclerosis: A Systematic Review With Meta-Analysis.\nAbstract: We aimed to provide updated evidence from the current literature regarding pediatric environmental factors associated with the risk of developing multiple sclerosis (MS). Articles were searched in PubMed, SciVerse ScienceDirect, and Web of Science. We included all clinical studies assessing the occurrence of MS at any age in association with the exposure to any environmental risk factor during childhood or adolescence. The main outcome was the occurrence of MS. The quality assessment was performed with the critical appraisal checklist for case-control studies. Pooled unadjusted effect sizes (OR) were calculated and reported with a 95% CI from random-effects meta-analysis. The review included 87 studies conducted across 20 countries. The studies analyzed diverse environmental risk factors, including infections, vaccinations, tobacco exposure, body mass index, and other pediatric exposures. EBV infection showed a significant positive association with MS risk (ES\u2009=\u20092.38, 95% CI\u2009=\u20091.80-3.15). Breastfeeding showed limited protective associations, and various adverse social experiences like bullying and sexual abuse were linked to increased MS risk. Active smoking during childhood/adolescence and obesity during these periods were associated with higher MS risk, while normal body mass index was protective. Antibiotic and chemical exposures, as well as vitamin D deficiency, were linked to higher MS risk. The review highlighted substantial heterogeneity and identified publication bias in studies on infections and vaccinations. Environmental risk factors for MS are important during childhood and adolescence. The first 20\u2009years are a key window for prevention and should be seen as an opportunity.\n\nID: 40939991\nTitle: The association between heavy metals co-exposures and depression: a convergence of network toxicology and epidemiology.\nAbstract: As neurotoxic agents, heavy metals have been implicated in depression pathogenesis, yet epidemiological evidence on metal mixture associations remain limited. This study examined associations between cadmium (Cd), lead (Pb), selenium (Se), manganese (Mn), and their mixtures with depression in US adults. Using 2011-2018 NHANES data from 8565 participants (\u226520\u00a0years), we applied logistic regression, weighted quantile sum (WQS) regression, and Bayesian kernel machine regression (BKMR) to evaluate individual and mixture associations. Subgroup analyses by age/sex, mediation analysis, and network toxicology for molecular mechanisms were conducted. The logistic regression revealed significant Cd-depression associations [OR (95\u00a0%CI): 1.46 (1.32, 1.61)]. Mixture analyses demonstrated positive exposure-response relationships, with Cd contributing 75.4\u00a0% to the WQS mixture index and exhibiting the strongest association in BKMR. Network toxicology identified CASP3, TNF, ALB, AKT1, and JUN as core genes, with oxidative stress, transcription factor Ap-1 complex and protein serine/threonine kinase inhibitor activity emerging as key mechanistic components. Our findings highlight heavy metal mixtures, particularly Cd-dominated combinations, exhibit significant depression associations, and reveal the neurotoxic synergy in metal mixtures and identify molecular targets for intervention.\n\nID: 40815455\nTitle: A narrative review of genetic and environmental factors and risk for multiple sclerosis. The design of the Italian multicentric PEDIGREE study.\nAbstract: MS is the result of an immune-mediated disorder triggered by environmental factors in subjects genetically predisposed. Pediatric MS (pedMS) offers a unique window to study environmental triggers, as\u00a0patients are close to the actual onset of the disease and have been exposed to fewer confounding\u00a0factors. PedMS is strongly associated to HLA-DRB1*15:01 and to non-MHC (Major Histocompatibility Complex) variants, with a higher burden compared to adults. HLA-A*02 allele seems to reduce MS risk. The role of rare variants is still under investigation. Several environmental causative factors have been identified: obesity, passive smoke, sun exposure, vitamin D, and others but the\u00a0strongest candidate is the Epstein-Barr virus, considered a prerequisite for MS development. In this paper we provide a summary of the results obtained so far in pediatric age. Some years ago, the Italian PEDIGREE study (PEDiatric\u00a0Italian\u00a0Genetic and enviRonmental\u00a0ExposurE) has been created to help clarify the role of genetic and environmental factors in pedMS, through a study of the genetic, epigenetic, metagenomic, transcriptomic, along with assessment of environmental factors (viral exposure, second-hand smoke and sun exposure, breastfeeding history, and other factors. A network of 29 Italian MS centers has been established, 154 pedMS patients (mean age 13.5\u00a0years) and matched controls have been recruited. For the genetic study, a cohort of 364 adult MS patients with onset\u2009<\u200918\u00a0years was included. The study is ongoing, the results of exposure to environmental risk factors and of genetic background will be available in the next future.\n\nID: 40553489\nTitle: Design and Synthesis of Novel Dual Inhibitors for JAK3 and TEC Kinases in Autoimmune Disorders.\nAbstract: Janus kinase 3 (JAK3) and tyrosine-protein kinase (TEC) play crucial roles in autoimmune diseases. Here, we report the optimization of JAK3/TEC dual covalent inhibitors through a series of rational design strategies. Through the fusion of a fluorine-substituted benzene ring to the piperidine, we achieved compound 8a with improved in vitro activity and selectivity and good drug-like properties. Compound 8a demonstrated excellent therapeutic efficacy in the experimental autoimmune encephalomyelitis (EAE) mouse model of multiple sclerosis orally, with no body weight loss, suggesting a preliminary indication of good safety. These findings support the potential of compound 8a as a promising candidate for the development of new therapies targeting JAK3 and TEC.\n\nID: 40527217\nTitle: Positive allosteric modulators of purinergic P2X4 receptors: design, synthesis and therapeutic potential of \"click\" ligands for multiple sclerosis.\nAbstract: The hypothesis of synthesizing novel allosteric modulators of purinergic P2X4 receptors was investigated based on click chemistry. A small library of 10 compounds designed from the tritopic pharmacophore structure of ivermectin (IVM), a natural selective allosteric modulator of P2X4 receptor, was efficiently synthesized using a 1,3,5-tris(1,2,3-triazole)benzene scaffold. The efficacy of the compounds, termed MSKs, was screened using voltage patch clamp electrophysiology in microglia cells to assess the specific impact on P2X4 channel kinetics and properties. Since IVM modulates both ion conduction and channel gating of P2X4, MSK compounds were evaluated separately for both parameters following ATP applications. Most compounds induced an increase in the maximal inward current (Imax) indicating enhanced ion conductance. Notably, compounds MSK-7 to MSK-10, bearing two rigid 3-piperidine substituents and a highly hydrophobic menthyl group, also reduced receptor deactivation (\u03c4off). The therapeutic potential of two selected compounds, MSK-5 and MSK-9, each exhibiting distinct mechanisms of interaction with the P2X4 receptor, was evaluated in experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis. Compound MSK-5 induced a modest yet significant amelioration of neurological symptoms during the chronic phase of EAE. In contrast, compound MSK-9 delayed EAE onset and showed a higher amelioration of neurological symptoms. We concluded that rigid trivalent click scaffolds constitute a novel class of non-natural platforms enabling the rapid development of positive allosteric modulators of P2X4 receptors that target both ion conductance and receptor deactivation. These results provide a solid foundation for future advances in the discovery of therapeutic lead candidates for multiple sclerosis.\n\nID: 40482960\nTitle: Berberine's paradox in Neurodegeneration: Therapeutic promise and safety challenges in Parkinson's disease.\nAbstract: Parkinson's disease (PD) is a chronic neurodegenerative disorder characterized by the progressive degeneration of dopaminergic neurons in the substantia nigra pars compacta (SNpc). \u03b1-Synuclein (\u03b1-Syn) is a key protein implicated in PD pathogenesis, with its structural and biophysical properties widely investigated due to their role in disease mechanisms. The presence of Lewy bodies and Lewy neurites, pathological hallmarks of PD primarily composed of aggregated \u03b1-Syn, further underscores its critical involvement. This correlation has led to the hypothesis that \u03b1-Syn aggregation actively contributes to PD development. Recent studies have implicated oligomers formed during the initial phases of protein aggregation as the primary neurotoxic agents driving cellular degeneration in PD. This pathological process worsens mitochondrial dysfunction, oxidative stress, and microglial activation, ultimately contributing to SNpc degeneration and PD progression. Currently, available PD medications only provide symptomatic relief and do not address underlying neuropathological mechanisms such as oxidative stress, mitochondrial impairment, \u03b1-syn aggregation, or SNpc degeneration. Moreover, long-term use of anti-PD drugs like L-DOPA can lead to motor complications and systemic side effects. As a result, repurposing traditional herbal medicines with antioxidant and anti-inflammatory properties presents a promising therapeutic approach. Studies suggest that berberine (BBR) may mitigate PD-related neuropathology. However, the exact mechanisms by which BBR exerts its neuroprotective effects remain unclear. This review explores the potential molecular pathways through which BBR could alleviate PD pathology.\n\nID: 40257326\nTitle: A network pharmacological target mendelian randomization study on the neuroprotective effects of\u00a0active ingredients in mahuang fuzi xixin decoction for multiple sclerosis.\nAbstract: Mahuang Fuzi Xixin Decoction (MFX), a traditional Chinese medicine containing 44 volatile components (97.36% total oil), includes key compounds like \u03b1-terpenol (13.34%) and 1,2,3-trimethoxy-5-methyl-benzene (22.64%). Using network pharmacology and Mendelian randomization, 24 active compounds were identified targeting MS-related pathways (NF-\u03baB, NLRP3, Toll-like receptor). Genetic variants in CYP450, GSK3B, CYBB, and PON1 correlated with reduced MS risk. In EAE mice, MFX decreased spinal GSK-3B expression (immunofluorescence) and pro-inflammatory factors (ELISA), demonstrating neuroprotection via anti-inflammatory, antioxidative mechanisms and restored GSK-3B levels, highlighting therapeutic potential for MS.\n\nID: 40175790\nTitle: Exploring the potential role of microtubule associated proteins-2 in the pathogenesis of HIV associated neurocognitive disorders.\nAbstract: HIV-associated neurocognitive disorder (HAND) persists in people living with HIV (PLWH) despite antiretroviral therapy. HAND is characterized by synapto-dendritic damage, yet the cause of this pathology is still under investigation. Various viral proteins, including the envelope protein gp120, have been proposed to be the leading neurotoxic agents underlying HIV-mediated neuronal degeneration. Gp120 has been shown to bind to neuronal microtubules (MTs) and impair their functions. The dynamic properties of MTs are modulated by microtubule-associated proteins (MAP), including MAP2, which is particularly abundant in dendrites. This review article explores how gp120 could be altering the function of the neuronal cytoskeleton by affecting MAP2. These effects may serve as a causal link between viral proteins and HAND pathology.\n\nID: 42547581\nTitle: CD44 as a Conserved Biomarker and Functional Modulator of Neuroinflammation in Multiple Sclerosis and Beyond.\nAbstract: Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS) characterized by demyelination, blood-brain barrier disruption, and leukocyte infiltration. The transmembrane glycoprotein cluster of differentiation 44 (CD44) has been implicated in neuroinflammation, but its functional role remains unclear. Here, we examined CD44 expression and function across both non-immune-mediated and immune-mediated MS animal models, including cuprizone-induced demyelination, experimental autoimmune encephalomyelitis (EAE), and combined cuprizone/EAE (Cup/EAE), as well as in human MS tissue and cerebrospinal fluid (CSF), using immunohistochemistry, flow cytometry and enzyme-linked immunosorbent assay. CD44 expression increased in parallel with demyelination and was most pronounced in the forebrain of Cup/EAE mice, where it localized to perivascular cuffs and lesion-associated parenchyma. CD44 expression co-localized to IBA1\u207a microglia/monocytes and CD3\u207a T cells. Flow cytometry analyses revealed high CD44 expression on myeloid-derived suppressor cells and regulatory T cells, which further increased upon immune activation. On the functional level, Cd44-deficient mice exhibited exacerbated disease severity in EAE, accompanied by increased immune cell infiltration and tissue damage. In human MS samples, CD44 expression and soluble CD44 levels in CSF were significantly elevated. Notably, CD44 upregulation was also observed in other neurological disease models, including ischemic stroke and APPswe/PS1dE9 mice, a model of Alzheimer's disease. Together, these findings identify CD44 as a conserved marker of neuroinflammatory activity and a context-dependent regulator of neuroinflammation with partially protective functions, rather than an exclusively pro-inflammatory molecule, highlighting its potential relevance in MS and related neurological disorders.\n\nID: 42530042\nTitle: Evaluation of the Behavioral and Histopathological Outcomes of Two Cuprizone Administration Routes in a Mouse Model of Multiple Sclerosis.\nAbstract: The cuprizone (CPZ) model has been used to study de- and re-myelination in mice; Previous studies have used different routes for CPZ intoxication, but the results were highly variable. Here, we compared demyelination induced by the administration of 0.3% CPZ mixed with ground rodent chow and a 400 mg/kg CPZ suspension in carboxymethyl cellulose (CMC) via oral gavage in SWR/J mice. The mice were assigned into a control group, a CPZ diet group, and an oral CPZ groups (n = 6 mice/group). Rotarod, hanging wire, and open field tests were performed to evaluate locomotor activity. Histological analyses were conducted on the corpus callosum (CC) of the brain to determine myelin loss and on the liver to assess the toxicity of CPZ. The administration of CPZ with ground rodent chow significantly reduced body weight gains, grip strength, and motor coordination performance during the 5-week demyelination period. In contrast, all analyzed parameters were less different in mice receiving CPZ via oral gavage. However, both CPZ routes significantly reduced myelin content in the CC. Additionally, the oral administration of CPZ had strong effects on liver toxicity compared to that of CPZ diet feeding. This study showed that both routes of CPZ intoxication could induce reproducible and consistent demyelination changes within the CC of the mouse brain, with the CPZ diet being more effective based on all analytical parameters and having fewer toxic effects on the liver compared with oral CPZ. In conclusion, the resultsassist in the selection of a suitable multiple sclerosis (MS) model for investigating disease mechanisms and therapies.\n\nID: 42507732\nTitle: Selective GPR17 antagonism enhances structural and functional recovery in animal models of demyelination.\nAbstract: Myelination, driven by differentiation of oligodendrocyte precursor cells, is critical for metabolic and structural support and efficient axonal signal transmission in neurons. Loss of myelin is a hallmark of multiple sclerosis and other devastating demyelinating disorders. As demyelination persists, neurons become increasingly vulnerable, leading to neurodegeneration and chronic disability. Restoring myelin through endogenous repair mechanisms offers a promising therapeutic approach to mitigate progressive neuronal loss. One key regulator of myelination is the G protein-coupled receptor 17, GPR17, whose chronic upregulation in oligodendrocyte precursor cells is commonly seen with myelin injury. In line with single-nucleus transcriptomic data showing predominant expression of GPR17 in committed oligodendrocyte precursor cells, our postmortem immunohistochemical analyses of MS patient tissue revealed a significant upregulation of GPR17+/BCAS1+ oligodendrocyte precursor cells adjacent to and in demyelinated lesions. Importantly, remyelinated lesions lacked GPR17 immunoreactivity, consistent with a model in which sustained GPR17 expression is associated with demyelination and impaired oligodendrocyte precursor cell differentiation. To test the impact of pharmacological GPR17 inhibition on remyelination, we evaluated the effects of a novel, selective GPR17 antagonist in cuprizone-induced murine demyelination models. This toxin-induced approach has been widely used to study mechanisms of de- and remyelination, in the absence of the full inflammatory complexity of demyelinating diseases such as multiple sclerosis. We show that oral treatment results in robust functional recovery consistent with remyelination, as evidenced by improved spatial memory and recovery of visual evoked potential latency delays. GPR17 antagonism also accelerated structural remyelination in the corpus callosum and optic nerve. Together, these findings support a role for pharmacological GPR17 antagonism in promoting remyelination and highlight this G protein-coupled receptor as a promising therapeutic target for demyelinating disorders.\n\nID: 42506315\nTitle: Nabiximols in Multiple Sclerosis: Beyond Spasticity-An Exploratory Systematic Review and Meta-Analysis of Symptomatic Outcomes.\nAbstract: Background/Objectives: Nabiximols, a standardized extract of Cannabis sativa, has been approved as an add-on therapy for patients with moderate to severe spasticity associated with multiple sclerosis (MS). Moreover, current Italian treatment algorithms suggest that cannabis-based therapies may have further relevance in the management of MS. The aim of our systematic review and meta-analysis was to assess the effectiveness of nabiximols in relieving symptoms other than spasticity in adult MS patients. Methods: A systematic search was conducted in Web of Science, MEDLINE (via PubMed), Cochrane CENTRAL and Embase on September 10, 2025. Study selection was performed according to the predefined PROSPERO protocol (CRD42022329952). Data were combined into a common denominator and examined using a random-effects model with meta-regression expressed as mean difference (MD) and a 95% confidence interval (CI). Risk of bias was assessed using the Cochrane risk of bias instrument (RoB2) and the Risk Of Bias In Non-randomized Studies of Interventions (ROBINS-I) tool. Results: Of the 49 eligible articles, 25 were included in the statistical analysis (2949 patients). Significant improvements in spasm quality (MD = -16.87; 95% CI = (-29.75)-(-3.99)), bladder function (MD = -16.38; 95% CI = (-22.18)-(-10.58)), sleep disruption (MD = -15.75; 95% CI = (-22.02)-(-9.49)) and gait function (timed walk MD(s) = -5.31; 95% CI(s) = (-9.88)-(-0.74)) were observed. Time-dependency was not significant. The subject global impression of change (SGIC) improved significantly after the first month (odds ratio (OR) = 1.69; 95% CI = (1.30)-(2.18)). Conclusion: Beyond spasticity, nabiximols may represent a signal of benefit for bladder function, sleep disruption, spasm quality, and gait function in MS, in line with the \"spasticity-plus\" concept. However, the evidence certainty was low to very low, and these findings should be considered exploratory.\n\nID: 42443579\nTitle: Eriochrome Cyanine R revisited: a standardized myelin stain protocol for thick sections of the central & peripheral nervous system across species, pathologies and disease models.\nAbstract: Myelin enables rapid action potential conduction and axonal support, and its disruption underlies diverse neurological disorders. Its assessment is essential for studying development, plasticity, and repair of the nervous system (NS), and for diagnosing demyelinating diseases and evaluating remyelination therapies. Multiple histological methods detect myelin, each with trade-offs in sensitivity, cost, and reproducibility. Among them, Eriochrome Cyanine R (EC-R) is a simple, affordable myelin stain widely used in thin sections, but remains poorly standardized, and underexplored in thick vibratome sections. Here we describe and validate a simple, inexpensive, solvent-free EC-R protocol for central and peripheral nervous system tissue across seven vertebrate species and multiple demyelinating conditions. The method replaces subjective microscopic differentiation with fixed, time-controlled incubations scaled to section thickness, improving reproducibility. Using perfusion and immersion-fixed samples, we show that the protocol yields homogeneous myelin labeling with sharp white/gray matter contrast in whole brains, cortical slabs, spinal cord, and peripheral nerves. Thick sections stained with EC-R preserve 3-dimensional tissue architecture, resolve single myelinated axons and intracortical bands, and can be combined with Nissl-like counterstains and immunohistochemistry. Developmental series in neonatal rats reveal expected PNS-CNS myelination gradients, while experimental demyelination models and naturally occurring diseases (canine distemper and human multiple sclerosis) illustrate the method's ability to delineate lesion cores, perilesional gradients, and associated glial and immune activation. This standardized EC-R approach provides a robust and versatile tool for comparative neuroanatomy, experimental neuropathology, and translational studies of myelination, demyelination, and remyelination, as well as for the clinical diagnosis of myelin-related disorders.\n\nID: 42401247\nTitle: Panax quinquefolius saponins promote remyelination via orchestrating HMGCS1-NPC1-MAL-mediated lipid metabolism and rebalancing JAK-STAT signaling in a cuprizone-induced demyelination model.\nAbstract: Panax quinquefolius L. is traditionally used as a \"Qi-tonifying and Yin-nourishing\" herb for weakness and limb flaccidity, symptoms described as \"Feng fei\" or flaccidity syndrome. These manifestations partially resemble motor dysfunction in multiple sclerosis (MS). Panax quinquefolius Saponins (PQS), are major bioactive constituents, but their effects on demyelination and related molecular changes remains unclear. To investigate the effects of PQS on demyelination and explore associated changes in inflammatory signaling and lipid metabolism. PQS was qualitatively profiled by UPLC-QTOF-MS and quantitatively standardized by HPLC-DAD. Male C57BL/6N mice were randomly divided into six groups (n\u202f=\u202f12-16/group): Control, Model (daily intragastric administration of 330\u202fmg/kg of cuprizone (CPZ) for 6 weeks), Positive control (10\u202fmg/kg of Clemastine), and low-, medium-, and high-dose PQS groups (25, 50, or 100\u202fmg/kg). During week 2-6, mice received drugs by daily intragastric administration. Behavioral assessments including pole test, rotarod, and open field test were performed. Myelin integrity and related molecular changes were evaluated by histological staining, immunofluorescence (IF), transcriptomics, Western blotting, and molecular docking. PQS ameliorated CPZ-induced motor dysfunction in behavioral assessments (P\u202f<\u202f0.05). PQS also attenuated myelin loss in the corpus callosum (CC), with the high-dose group increasing myelinated areas to approximately 74% of control levels (P\u202f<\u202f0.01). Transcriptomic and protein analyses showed that PQS downregulated JAK1/STAT3/NLRP3 inflammatory pathway. In parallel, the HMGCS1-NPC1-MAL axis was upregulated, accompanied by increased mevalonate (MVA) and total cholesterol (TC) levels (P\u202f<\u202f0.05) and reduced PLIN2 expression (P\u202f<\u202f0.001), suggesting decreased lipid droplet accumulation and altered cholesterol metabolism.Molecular docking predicted ginsenosides Rb3, Rk3, Re, Rc, Ro, and Rf may interact with targets related to inflammatory and lipid metabolism. PQS supported myelin restoration, which is correlated with a modulation of the JAK-STAT signaling pathway and HMGCS1/NPC1-associated lipid homeostasis. PQS may represent a potential therapeutic lead for demyelinating diseases, although mechanisms require further validation.\n\nID: 42400730\nTitle: Neuroprotective potential of resveratrol in Parkinson, Huntington, amyotrophic lateral sclerosis, and multiple sclerosis: a comprehensive review.\nAbstract: Resveratrol shows neuroprotective effects in preclinical studies across a number of neurodegenerative illnesses, including Parkinson's disease (PD), Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), and Huntington's disease (HD), and it enhances mitochondrial function through stimulation of the AMPK/SIRT1/PGC-1\u03b1 pathway, thereby improving mitochondrial oxidative capacity and ATP generation. The natural polyphenol lowers \u03b1-synuclein accumulation and affects autophagy; both markers of PD. Combining nano\u2011resveratrol formulations with L\u2011DOPA has shown greater therapeutic efficacy in animal models (MPTP mouse), while co\u2011administration with EGCG has shown synergistic neuroprotection in vitro (SH\u2011SY5Y cells). These combination strategies offer potential advantages in neuroprotection and symptom alleviation while minimizing adverse drug effects. Resveratrol activates SIRT1 and AMPK signaling in preclinical models, enhancing mitochondrial biogenesis, lowering apoptosis, and restoring cellular resilience. The effectiveness of various models and dosages varies. The primary mechanism by which resveratrol promotes neuronal survival and remyelination in multiple sclerosis is through SIRT1 activation, which does not directly reduce inflammation. As innovative delivery systems, intranasal nanoparticles and exosomes produced from macrophages have shown improved CNS targeting accuracy. Resveratrol slows down neurodegeneration and improves the prognosis of HD by improving motor function and stimulating mitochondrial biogenesis in addition to activating neuroprotective ERK signaling. All of these results point to resveratrol's several pathways as a strong contender for neurodegenerative disease adjunctive treatment. The current evidence base is insufficient to support clinical use of resveratrol for any of the four diseases. Further rigorous preclinical studies (including TDP-43 models for ALS, SIRT1 knockout studies, and human-feasible dosing) and well-designed clinical trials with pharmacokinetic endpoints are required before any clinical recommendations can be made.\n\nID: 42392741\nTitle: [Dihydroartemisinin ameliorates inflammation in experimental autoimmune encephalomyelitis by enhancing AXL signaling in microglia].\nAbstract: This study aimed to investigate the mechanism of dihydroartemisinin(DHA) in ameliorating multiple sclerosis(MS). Hematoxylin and eosin(HE) staining was used to assess inflammatory cell infiltration, while luxol fast blue(LFB) staining and electron microscopy were performed to evaluate myelin sheath structure. In cell experiments, this study measured programmed cell death ligand 1(PD-L1) expression on BV2 cells and forkhead box protein p3(Foxp3) expression in Jurkat T cells co-cultured with BV2 cells, determined the C-C motif chemokine ligand 5(CCL5) concentration in the supernatant of BV2 cells, and evaluated BV2 cell chemotaxis. Western blot(WB) was performed to detect protein levels of receptor tyrosine kinase(AXL), phosphorylated AXL(p-AXL), signal transducer and activator of transcription 1(STAT1), phosphorylated STAT1(p-STAT1), and suppressors of cytokine signaling 3(SOCS3). To confirm the role of AXL, key cellular assays were repeated following inhibition of AXL. Additionally, under physiological conditions, the effects of DHA on body weight, spleen weight, and peripheral blood immune cell profiles were examined. The results showed that DHA significantly reduced disease scores, attenuated body weight loss, suppressed inflammatory infiltration, and promoted myelin sheath repair in experimental autoimmune encephalomyelitis(EAE) mice. At the cellular level, DHA upregulated PD-L1 expression on BV2 cells and Foxp3 expression in co-cultured Jurkat cells, and inhibited CCL5 release and BV2 cell chemotaxis. It also upregulated AXL, p-AXL, p-STAT1, and SOCS3 protein expression in BV2 cells. When AXL was inhibited, these effects are nullified. In healthy mice, DHA did not have any effect on their various parameters. In conclusion, DHA maintains inflammatory homeostasis in the EAE model by activating the AXL signaling pathway in microglia.\n\nID: 42387200\nTitle: Tetrahydrocannabinol/cannabidiol in the treatment of restless legs syndrome.\nAbstract: Dopamine agonists were previously considered the first-line treatment for Restless Legs Syndrome (RLS); however, \u03b12\u03b4 ligands are now recommended to prevent augmentation. As cannabinoids inhibit glutamate release in the striatum, they may represent an effective therapeutic option for RLS. Evaluate the efficacy of 2.7\u00a0mg \u03949Tetrahyedrocannabinol/2.5\u00a0mg Cannabidiol (2.7mgTHC/2.5mgCBD) in RLS. This is an exploratory, prospective, 3-month open-label trial. At baseline, patients underwent blood testing, respiratory polygraphy, and a 14-day actigraphy. Treatment was initiated at baseline, with dose titration at week 4 if required. The Expanded Disability Status Scale (EDSS), Epworth Sleepiness Scale (ESS), International Restless Legs Syndrome Rating Scale (IRLS), Modified Ashworth Scale, and EQ-5D were assessed at baseline and at weeks 4 and 12. The 14-day actigraphy was repeated at week 12. The primary endpoint was improvement in IRLS scores. Sleep parameters were evaluated as secondary endpoints. Primary end point: improvement in IRLS. Sleep parameters were secondary end points. Eighteen patients with RLS were included, of whom 16 had multiple sclerosis (MS). The cohort comprised 55.5% women, with a mean age of 51.87\u00a0years, a median EDSS score of 2, and a mean Ashworth score of 1\u2009\u00b1\u20091.19. Median iron metabolism parameters were within the normal range. At baseline, patients exhibited low daytime sleepiness (ESS: 10.63\u2009\u00b1\u20093.46) and severe RLS (IRLS: 22.44\u2009\u00b1\u20098.77). Mean sleep efficiency (SE) was 83.64\u2009\u00b1\u20096.03%, sleep latency (SL) was 26.71\u2009\u00b1\u200918.64\u00a0min, and wake after sleep onset (WASO) was 40.29\u2009\u00b1\u200910.03\u00a0min. IRLS scores improved significantly after both 1 month and 3 months of treatment (p\u2009<\u20090.001). WASO was significantly reduced (p\u2009=\u20090.015), whereas no significant changes were observed in SL or SE. After 1\u00a0year, 66.66% of patients remained on treatment and continued to show sustained improvement in IRLS scores (p\u2009=\u20090.000). In this exploratory open-label study, treatment with 2.7\u00a0mg THC/2.5\u00a0mg CBD was effective in reducing RLS severity, as measured by the IRLS scale, in patients with MS and-associated idiopathic RLS. Improvements were observed after 1 and 3 months of treatment and were maintained after 1\u00a0year among patients who continued therapy.\n\nID: 42370465\nTitle: Evaluating the effectiveness of simvastatin in slowing the progression of disability in secondary progressive multiple sclerosis: a synopsis of MS-STAT2, a multicentre, randomised controlled, double-blind, phase 3 clinical trial.\nAbstract: Despite the relative success of immuno-modulatory disease-modifying therapy in relapsing remitting multiple sclerosis, progressive worsening of disability remains a major problem, particularly for those with secondary progressive multiple sclerosis. Various underlying mechanisms are likely to contribute, augmented by comorbidities (such as vascular risk) and ageing. In the phase 2b MS-STAT trial, simvastatin (80\u2005mg) (Sandoz Ltd, Camberley, UK) reduced the mean annualised whole brain atrophy rate by 43% compared to placebo in patients with secondary progressive multiple sclerosis (p\u2005=\u20050.003). We now report the phase 3, MS-STAT2 trial, with confirmed progression of disability as the primary outcome. A multicentre, phase 3, randomised, double-blind, placebo-controlled clinical trial was conducted at 31 UK neuroscience centres and district general hospitals. Secondary progressive multiple sclerosis participants aged 18-65 years were randomised 1\u2005:\u20051 to oral simvastatin (80\u2005mg), or matched placebo, based on a minimisation algorithm that incorporated the following factors: sex (male/female); age (< or \u2265\u200545 years); Expanded Disability Status Scale baseline score (\u2264\u20055.5 or \u2265\u20056); whether participants were taking newly licensed (2017 onward) disease-modifying treatments for secondary progressive multiple sclerosis; and trial site. An independent and secure online randomisation service was used. All participants, site investigators and the trial co-ordinating team were blinded to treatment allocation. The Expanded Disability Status Scale was measured every 6 months and was compared to baseline scores, with remote data collection used when enforced by the COVID-19 pandemic. The primary outcome was time to Expanded Disability Status Scale-confirmed disability progression. Progression of disability was defined as an increase of at least one point on the Expanded Disability Status Scale if the baseline score was <\u20056, or an increase of 0.5 point if the baseline score was \u2265\u20056. The initial disability progression event was finalised as confirmed if the increase in Expanded Disability Status Scale score persisted at the next assessments \u2265\u20056 months later. Follow-up was for 36 months, or 54 months, for those without confirmed disability progression at 36 months who agreed to enter an optional blinded extension. An intention-to-treat analysis was carried out. The study was conducted between 10 May 2018 and 26 July 2024. There were 964 participants randomised, with 482 in the placebo group and 482 in the simvastatin group. 173 (35.9%) participants in the placebo group and 192 (39.8%) participants in the simvastatin group experienced Expanded Disability Status Scale-confirmed disability progression (adjusted hazard ratio =\u20051.13, 95% confidence interval 0.91 to 1.39, p\u2005=\u20050.263). No material differences in the secondary outcomes were observed. No major safety issues were seen. The MS-STAT2 trial did not demonstrate a treatment effect of simvastatin in slowing disability progression in participants with secondary progressive multiple sclerosis. Despite the favourable outcomes of the previous phase 2b trial, simvastatin use in secondary progressive multiple sclerosis should be confined to existing vascular indications. This synopsis presents independent research funded by the National Institute for Health and Care Research (NIHR) Health Technology Assessment programme as award number 15/57/143. Multiple sclerosis is a lifelong condition that affects the brain and spinal cord. Many people with multiple sclerosis start with a type called relapsing-remitting multiple sclerosis, which can later become secondary progressive multiple sclerosis. Secondary progressive multiple sclerosis causes steady worsening of disability over time, and currently, there are very few treatment options for people without signs of active inflammation. Simvastatin is a cholesterol-lowering drug (a statin) that is widely used for heart disease. Earlier research (the Simvastatin in Secondary Progressive Multiple Sclerosis phase 2 trial) suggested that high-dose simvastatin might slow brain shrinkage and disability in people with secondary progressive multiple sclerosis. To test this further, researchers ran a large phase 3 clinical trial called Simvastatin in Secondary Progressive Multiple Sclerosis (phase 3 trial), involving 964 participants across the United Kingdom. Half were given simvastatin and half a placebo, and they were followed up while continuing to take these for 3 years. For participants whose disability was stable at 3 years, they could continue in the trial on the same medication for up to 4.5 years if they were happy to do so. The main aim was to see if simvastatin could slow down worsening disability, which was measured using a scale called Expanded Disability Status Scale. The Expanded Disability Status Scale data were mainly collected at face-to-face appointments, but some assessments were conducted by telephone when enforced by the COVID-19 pandemic. The results showed no significant difference between the simvastatin and placebo groups. Simvastatin did not delay disability progression. The trial also looked at other outcomes such as walking speed, hand function, memory and quality of life. Again, there were no meaningful differences. Importantly, simvastatin was generally safe, and side effects were rare. The trial also found that people with higher disability levels faced higher personal and financial costs, and many relied on unpaid care from family or friends. Overall, the Simvastatin in Secondary Progressive Multiple Sclerosis phase 3 trial provides clear evidence that simvastatin does not have a therapeutic effect in slowing disability progression in people with secondary progressive multiple sclerosis. It also offers valuable insights for future research into progressive multiple sclerosis and highlights the need for new treatments that target the disease\u2019s underlying causes.\n\nID: 42364973\nTitle: PBPK Modeling and Clinical Data Reveal Reduced Impact of CYP3A4 and CYP2C9 Inhibitors on Elimination of Siponimod.\nAbstract: Multiple sclerosis (MS) is a significant cause of neurological disability in young adults. Siponimod, a potent sphingosine-1-phosphate (S1P) receptor modulator, is used to treat MS by reducing T-cell recirculation and central inflammation. The presented work includes clinical data describing the impact of the CYP3A4 inhibitor clarithromycin on siponimod metabolism and the results of updated physiologically based pharmacokinetic (PBPK) modeling. A clinical drug-drug interaction (DDI) study assessed the effect of clarithromycin on siponimod pharmacokinetics in healthy participants with the CYP2C9*1*3 genotype. Results revealed minimal differences in PK: a 2% increase in Cmax, an 8% increase in AUClast and a 9% increase in AUCinf, confirming no clinically relevant drug-drug interaction (DDI). The existing siponimod PBPK model was updated using these DDI study data, estimating a CYP3A4 fraction metabolized of 6.4% in the CYP2C9*1*1 genotype. Simulations using the updated PBPK model in the absence and presence of the restricted co-medication (CYP2C9 and CYP3A perpetrators) were conducted. There was no clinically relevant DDI with moderate and strong CYP3A4 inhibitors across CYP2C9 genotypes with a predicted maximum net AUC increase of 1.33. Co-administration of fluconazole, a moderate CYP3A4 and CYP2C9 inhibitor, was predicted to result in <\u20092-fold net AUC increase, except for the genotype CYP2C9*2*2, where a 2.2-fold net AUC increase compared to the CYP2C9 wild type without fluconazole co-treatment was observed. Siponimod Cmax and AUC were comparable across CYP2C9 genotypes during dose titration in the absence or presence of fluconazole, suggesting no impact on the effectiveness of the dose titration regimen.\n\nID: 42356263\nTitle: The Effect of Polyphenol Supplementation in People with Multiple Sclerosis: A Systematic Review of Clinical Trials.\nAbstract: Background/Objectives: Multiple sclerosis (MS) is an autoimmune neuroinflammatory disease affecting 2.9 million worldwide. Current immunosuppressive treatments offer limited neuroprotection and often cause adverse effects. Polyphenols with antioxidant and anti-inflammatory properties have been investigated as adjuncts in MS. Methods: On 19 June 2025, Embase, Medline, and ClinicalTrials.gov were systematically searched. Eligible clinical trials assessing polyphenol supplementation in MS were included. Outcomes of interest were Expanded Disability Status Scale (EDSS), annualised relapse rate (ARR), magnetic resonance imaging (MRI) changes, safety, and tolerability. Risk of bias was evaluated using the Cochrane tool, and certainty of evidence was appraised with Grading of Recommendations Assessment, Development, and Evaluation (GRADE). The protocol was registered with PROSPERO (CRD420251052042). Results: Of 870 records identified, 13 trials (n = 785) met inclusion. Nanocurcumin consistently improved EDSS in relapsing-remitting MS (3 trials, n = 150; p = 0.039-0.041), while epigallocatechin-3-gallate, silymarin (SM), cranberry extract, and bio-enhanced curcumin extract (BCM-95) curcumin showed no significant impact on disability, relapse rates, or MRI outcomes. Intervention adverse events were generally mild. SM showed potential hepatoprotective effects. Risk of bias was determined as low risk for seven of the trials and of some concern for five of the studies. Most often raising concerns because of selective reporting. Certainty of evidence, assessed using GRADE, was generally moderate, indicating some uncertainty regarding the outcomes. Meta-analysis was not possible due to the heterogeneity of included studies. Conclusions: Nanocurcumin may contribute to improvements in disability outcomes in Relapse Remitting Multiple Sclerosis (RRMS), whereas other polyphenols lack consistent efficacy. However, the evidence base remains limited by small sample sizes and methodological concerns. Larger, multicentre randomised controlled trials are required to establish optimal dosing, long-term safety, and therapeutic potential.\n\nID: 42343001\nTitle: Therapeutic evaluation of artocarpin-enriched extract from Artocarpus heterophyllus heartwood in multiple sclerosis rat model.\nAbstract: Neuro-inflammation leads to the development of neurological disorders such as multiple sclerosis (MS) by promoting demyelination in Central nervous system (CNS). Due to limitations in the efficacy and side effects of the currently available treatments of MS this study is designed to explore neuroprotective role of artocarpin enriched extract (AEE) of Artocarpus heterophyllus heartwood as a favorable natural therapeutic substitute in MS. AEE was prepared from the heartwood of A. heterophyllus using a green microwave-assisted extraction technique. To assess the safety profile of AEE acute toxicity assessment was performed in accordance with OECD guidelines. Molecular docking analysis was performed to analyze the binding affinity and interaction behavior of artocarpin against multiple therapeutic targets S1PR1, MMP-9, BTK, IL-17, TNF-\u03b1 and NLRP3. For the therapeutic evaluation of AEE, in cuprizone (CPZ) induced demyelination, forty-two Wistar albino rats were selected and evenly distributed into seven groups: Normal control (NC), disease control (DC), standard treatment drug (fingolimod, 15\u00a0mg/kg, pure artocarpin (AC) 100\u00a0mg/kg and three treatment groups receiving AEE at dose of 200\u00a0mg, 400\u00a0mg, and 800\u00a0mg/kg. Neuroinflammation was induced in all groups except NC by administering 0.2% w/w 450\u00a0mg/kg cuprizone for 42 days. Behavioral assessments, biochemical analyses, histopathological examinations, gene expression and neurotransmitter level were observed to explore the meyelin protection effects of AEE. Results demonstrated that pure artocarpin and AEE produced significant effects in the protection of neuron myelin sheath and can be considered as a suitable therapeutic agent for further study in MS.\n\nID: 42329180\nTitle: Growth Differentiation Factor 11 Is a Circulating Regulator of Oligodendrocyte Differentiation and CNS Myelin Formation and Repair.\nAbstract: Remyelination failure is a major contributor to progressive neurological disability in multiple sclerosis (MS). Although oligodendrocyte progenitor cells (OPCs) persist in demyelinated lesions, they often fail to differentiate into myelinating oligodendrocytes. This study aimed to determine whether growth differentiation factor 11 (GDF11), a circulating member of the TGF-\u03b2 superfamily, regulates oligodendrocyte differentiation, CNS myelination, and remyelination. The effects of GDF11 were examined using purified mouse OPC cultures, a neonatal developmental myelination model, and two demyelination models: cuprizone-induced demyelination and experimental autoimmune encephalomyelitis (EAE). OPC differentiation was assessed by immunocytochemistry and morphological analysis. In\u00a0vivo myelination and remyelination were evaluated using histological, ultrastructural, and behavioral approaches following systemic GDF11 administration. GDF11 directly promoted OPC differentiation and maturation in\u00a0vitro without affecting proliferation. Systemic GDF11 enhanced developmental myelination in neonatal mice, increasing myelin gene expression, myelinated axon density, and myelin thickness. Although GDF11 did not prevent active demyelination, it significantly accelerated remyelination and functional recovery following cuprizone withdrawal and in the EAE model, and this was accompanied by enhanced oligodendrocyte differentiation and reduced neuroinflammation. These findings identify GDF11 as a circulating regulator of oligodendrocyte maturation and CNS myelin formation and repair, highlighting its therapeutic potential for demyelinating diseases.\n\nID: 42292352\nTitle: Disease outcomes with ublituximab in treatment-na\u00efve participants: subpopulation analyses of the phase 3 ULTIMATE I and II studies in participants with relapsing multiple sclerosis.\nAbstract: Evidence suggests that treating relapsing multiple sclerosis (RMS) initially with a high-efficacy disease-modifying therapy (DMT) is superior to an escalating approach at reducing disability progression and relapse rate. To evaluate the efficacy of ublituximab versus teriflunomide in participants without prior DMT (treatment-na\u00efve population) and in a subset of treatment-na\u00efve participants with symptom onset \u2264 three years (early treatment subpopulation). Pooled post hoc analyses of ULTIMATE I/II were conducted at Week 96. The annualized relapse rate was 0.081 for ublituximab (n =\u00a0345) versus 0.188 for teriflunomide (n =\u00a0377) (p <\u00a00.001) in the treatment-na\u00efve population and 0.130 for ublituximab (n =\u00a0139) versus 0.334 for teriflunomide (n =\u00a0140) in the early treatment subpopulation (p =\u00a00.004). Twelve-week confirmed disability improvement rates were 10.7% versus 5.3% (p =\u00a00.010) in the treatment-na\u00efve population and 14.4% versus 3.6% (p =\u00a00.002) in the early treatment population (ublituximab vs. teriflunomide). Significant reductions in gadolinium-enhancing T1 lesions and new/enlarging T2 lesions, respectively, occurred for ublituximab versus teriflunomide (treatment na\u00efve: 0.031 vs. 0.791 and 0.390 vs. 4.144; p\u00a0<\u00a00.001 for both; early treatment: 0.051 vs. 1.030 and 0.508 vs. 6.068; p\u00a0<\u00a00.001 for both). Ublituximab was associated with significant treatment benefits at Week 96 in treatment-na\u00efve participants and those receiving treatment within three years of symptom onset. https://clinicaltrials.gov/study/NCT03277261 and https://clinicaltrials.gov/study/NCT03277248, identifiers NCT03277261 and NCT03277248.\n\nID: 42274557\nTitle: Quantitative Assessment of GFAP-Based Astrocyte Morphology in the Cuprizone Model: A Comparative Evaluation of Neurolucida\u00ae 360 and SNT.\nAbstract: Reactive astrocytes are a hallmark of several neurological diseases in multiple sclerosis and experimental demyelination models. Their morphological alterations are commonly assessed by qualitative histopathology, yet quantitative tools are required to better capture astrocytic heterogeneity and to allow correlations with imaging-derived biomarkers. Here, we present a workflow for the quantitative analysis of Glial Fibrillary Acidic Protein (GFAP) network remodeling in astrocytes in the cuprizone model of demyelination. C57BL/6 mice were intoxicated with cuprizone for 3 or 5 weeks to induce progressive demyelination, microglial activation, and reactive astrogliosis. Brain sections were processed for anti-GFAP immunohistochemistry, and individual astrocytes from the stratum oriens of the hippocampus were digitally reconstructed. Diverse parameters of GFAP topology, including soma size, process length, branching order, convex hull area, and ramification index, were extracted using either the commercial Neurolucida\u00ae 360 software or the open-source Simple Neurite Tracer (SNT) plugin in ImageJ. Principal component analysis revealed clear differences between control astrocytes and astrocytes in cuprizone-intoxicated animals, with reactive astrocytes displaying increased numbers of primary processes, enhanced bifurcation, and process complexity. Comparative evaluation of Neurolucida\u00ae 360 and SNT demonstrated that both tools are suitable for astrocyte reconstruction, although Neurolucida\u00ae 360 enabled faster and more detailed tracing. This protocol provides a reproducible pipeline for the quantitative assessment of astrocyte morphology under control and pathological conditions, thereby supporting future efforts to link cellular remodeling to functional outcomes in neuroinflammatory disease models.\n\nID: 42257510\nTitle: Progression to Wheelchair in Secondary Progressive Multiple Sclerosis and Impact of Siponimod: Post Hoc Analyses From the EXPAND Study.\nAbstract: Delaying time to requiring a wheelchair in people living with MS is an important treatment goal to maintain quality of life and guard against increased healthcare costs. In this post hoc analysis, the effects of siponimod versus placebo on time to sustained Expanded Disability Status Scale (EDSS) \u2265\u20097.0 over the core part of the Phase 3 EXPAND study were assessed. The time to sustained EDSS \u2265\u20097.0 (time to requiring a wheelchair) was analysed for participants with secondary progressive multiple sclerosis (SPMS). Analyses were based on a While on Treatment (WOT) set that censored participants if entering open-label treatment. Subgroup analyses were conducted in participants with active versus non-active SPMS (defined based on pre-study/baseline criteria), and in participants with baseline EDSS 6.5. In the overall EXPAND population, siponimod reduced the risk of reaching sustained EDSS \u2265\u20097.0 (requiring a wheelchair) by 40% (hazard ratio [HR], 0.60; 95% confidence interval [CI], 0.41-0.88; p\u2009=\u20090.009) versus placebo; the reduction in risk was 51% (HR, 0.49; 95% CI, 0.29-0.81; p\u2009=\u20090.005) versus placebo in participants with active SPMS and 22% (HR, 0.78; 95% CI, 0.42-1.45; p\u2009=\u20090.437) in non-active SPMS. Siponimod reduced the risk of requiring a wheelchair in participants with SPMS versus participants receiving placebo, with a greater effect in those with active disease. Time to requiring a wheelchair is a highly relevant treatment goal and an important indicator of treatment effect in patients with SPMS.\n\nID: 42247418\nTitle: Fasciola hepatica excretory-secretory products attenuate demyelination and reduce neuroinflammation in the Cuprizone -induced multiple sclerosis model.\nAbstract: Multiple sclerosis (MS) is characterized by chronic neuroinflammation and progressive demyelination, with current therapies failing to adequately address both processes simultaneously. Helminth-derived excretory-secretory products (ESP) are immunomodulatory molecules that suppress host inflammation and are promising candidates for MS treatment. However, their capacity to promote remyelination remains poorly understood. This study investigated the effects of Fasciola hepatica ESP in the cuprizone-induced demyelination model. Male C57BL/6 mice were divided into four groups: control (CON), control\u2009+\u2009FES (CON\u2009+\u2009FES), cuprizone (CUP), and cuprizone\u2009+\u2009FES (CUP\u2009+\u2009FES). FES was administered intraperitoneally during the demyelination phase. Motor and cognitive functions were evaluated using open field, rotarod, wire grip, and shuttle box tests. Neuroinflammation was assessed by measuring TNF and IL-1\u03b2 levels, while myelin-related changes were evaluated by MBP and Olig2 expression (ELISA and qPCR) and Luxol Fast Blue staining. FES treatment significantly reduced pro-inflammatory cytokines, increased MBP and Olig2 levels, improved myelin integrity, and enhanced motor and cognitive performance compared to untreated cuprizone mice, though full recovery to control levels was not achieved. These findings demonstrate that FES attenuates neuroinflammation and is associated with partial improvements in myelin-related outcomes in the cuprizone model, supporting the therapeutic potential of helminth-derived molecules for MS.\n\nID: 42234285\nTitle: The Myelin-Derived Peptide NSDP1 Suppresses Neuroinflammation and Attenuates Demyelination in Chronic Cuprizone-Fed Mice via Modulation of cGAS-STING Signaling.\nAbstract: Multiple sclerosis (MS) is characterized by demyelination and neuroinflammation. In a cuprizone (CPZ)-induced demyelination mouse model, proteomic analysis revealed the significant downregulation of a myelin basic protein-derived peptide (sequence: DTGILDSIGRFFS), which we have designated as NSDP1 (nervous system-derived peptide 1). In vitro, NSDP1 suppressed LPS-induced microglial activation in BV2 cells, reducing reactive oxygen species (ROS) production, downregulating pro-inflammatory markers (iNOS, TNF-\u03b1, IL-1\u03b2), and upregulating the expression of anti-inflammatory marker Arg-1. In vivo, NSDP1 administration via intracerebroventricular injection significantly mitigated CPZ-induced weight loss and demyelination in the corpus callosum. NSDP1 attenuated CPZ-induced demyelination, restoring expression of myelin proteins (MAG, MOG), increasing oligodendrocyte precursor cell (OPC) density, improving myelin sheath ultrastructure, and enhancing axonal myelination efficiency. Furthermore, NSDP1 attenuated CPZ-induced reactive gliosis, reducing both microglial activation and astrocytic reactivity in the corpus callosum. RNA sequencing revealed that NSDP1 modulated myelination-related pathways and correlated with improved locomotor recovery. Mechanistically, NSDP1 exerted its anti-inflammatory effects by inhibiting the cGAS-STING signaling pathway, as shown by reduced cGAS and STING expression in LPS-stimulated BV2 cells. The effects of NSDP1 on ROS and pro-inflammatory cytokine release were reversed by the STING activator DMX and mimicked by the STING inhibitor SN-011. Collectively, these findings identify NSDP1 as a downregulated myelin-derived peptide with potent therapeutic potential, which attenuates demyelination and suppresses neuroinflammation in demyelinating diseases by inhibiting the cGAS-STING pathway.\n\nID: 42220502\nTitle: Case Report: Marburg variant of multiple sclerosis and review of its complicated treatment.\nAbstract: Marburg variant of multiple sclerosis (MS) is a rare, fulminant demyelinating disorder characterized by rapid neurological decline and notable lack of established standardized treatment guidelines. We describe a 46-year-old woman presenting with progressive cognitive and behavioral changes and multifocal CNS lesions initially refractory to corticosteroids, plasmapheresis (PLEX), and intravenous immunoglobulin (IVIg). Brain biopsy confirmed aggressive MS-spectrum demyelination. Escalation to high-dose cyclophosphamide resulted in radiologic stabilization but was limited by severe, refractory cytopenia. Given persistent disease activity and intolerance to infusion-based therapy, transition from ocrelizumab to subcutaneous ofatumumab was planned as a pragmatic maintenance strategy; however, treatment initiation was delayed. The patient subsequently experienced rapid clinical deterioration marked by recurrent aspiration events and functional decline, ultimately leading to death following transition to comfort-focused care. This case highlights the therapeutic challenges of Marburg MS, including treatment-limiting toxicity, logistical barriers to anti-CD20 therapy, and the critical importance of timely, individualized immunosuppressive strategies.\n\nID: 42207934\nTitle: Unveiling Remyelinating Properties of Roflumilast in CPZ-Induced Neuronal Demyelination in Mice.\nAbstract: Multiple sclerosis (MS) is a demyelinating disorder characterized by oligodendrocyte apoptosis, microglial activation at demyelination sites, with ROS production. These pathological processes are closely associated with phosphodiesterase-4 (PDE-4) activity. Roflumilast (ROFL), a selective PDE-4 inhibitor, has demonstrated neuroprotective effects in various central nervous system disorders. However, its specific role in MS pathogenesis remains to be fully elucidated. This study aims to investigate the effects of ROFL on oligodendrocyte maturation, microglial polarization and the impact on protein kinase A/cAMP-response element binding protein pathway. An MS model was induced in mice via dietary administration of cuprizone (CPZ) for 7 days, starting with 0.7% (w/w), followed by 0.2% for 5 weeks. Beginning in week 5, mice received ROFL (5\u2009mg/kg/day, p.o) for 2 weeks. ROFL improved the motor abnormalities in the rotarod and open field tests. Together, ROFL downregulated the PDE4/cAMP-dependent pathway, exerting anti-inflammatory effects by suppressing NF-\u03baB and TNF-\u03b1. Additionally, microglial polarization shifted toward the anti-inflammatory M2 phenotype, with CD163 increment, in contrast to the pro-inflammatory M1 marker CD83. Furthermore, ROFL's antioxidant capacity was evidenced by reduced malondialdehyde levels, replenishment of glutathione levels, and reduced phosphorylation of ERK1/2. Oligodendrocyte differentiation and maturation were enhanced, as indicated by elevated levels of proteolipid protein, myelin-associated glycoprotein, CNPase, and myelin basic protein. Remyelination was confirmed through Luxol fast blue staining, accompanied by reduced apoptotic marker, caspase-3, in oligodendrocytes. Collectively, these findings suggest that ROFL exerts neuroprotective effects and highlight the therapeutic potential of PDE-4 inhibition as a strategy for MS treatment.\n\nID: 42196494\nTitle: Spatiotemporal APLNR Expression Dynamics During Oligodendroglial Remodeling of the Corpus Callosum in the Cuprizone Model.\nAbstract: Demyelinating disorders such as multiple sclerosis are characterized by oligodendrocyte loss and insufficient remyelination. The cuprizone model provides a well-established experimental system for studying these processes. The apelinergic system, including the apelin receptor (APLNR), has been implicated in neuroprotection and central nervous system homeostasis. However, its role in white matter demyelination and repair remains incompletely understood. This study aimed to characterize the spatial and temporal dynamics of APLNR expression in relation to oligodendrocyte lineage cells in the corpus callosum (CC) during demyelination and remyelination. Demyelination was induced in 8-week-old C57BL/6 mice by 0.2% cuprizone supplementation in their drinking water for 5 weeks, followed by 5 weeks remyelination phase after toxin withdrawal. Histological assessment using Luxol Fast Blue/Cresyl violet staining was performed to evaluate structural changes in the CC. Immunohistochemistry and confocal microscopy were used to analyze APLNR expression, GST-\u03c0+ cells, and NG2+ cells, including their spatial distribution and co-localization. Quantitative analyses and correlation tests were conducted to assess relationships between cellular markers and CC area. Demyelination resulted in significant reduction in CC area and a marked decrease in GST-\u03c0+ cells, accompanied by a robust increase in NG2+ cells, while remyelination led to partial structural and cellular recovery. APLNR expression increased progressively from control to demyelination and further during remyelination, exhibiting pronounced regional heterogeneity with higher levels in lateral CC regions. Confocal analysis demonstrated increasing co-localization of APLNR with NG2+ cells, particularly during remyelination. Correlation analyses identified GST-\u03c0+ cell density as the strongest predictor of CC area, whereas APLNR showed phase-dependent associations, including a positive correlation with GST-\u03c0+ cells during remyelination and a negative relationship with NG2+ cells during demyelination. APLNR expression is dynamically regulated during cuprizone-induced demyelination and remyelination and is closely associated with oligodendrocyte lineage cell responses. Its increased expression and enhanced co-localization with NG2+ cells during remyelination suggest a potential role in endogenous repair processes. However, as the findings are based on descriptive analyses, further functional studies are required to determine the mechanistic contribution of APLNR signaling and its potential as a therapeutic target in demyelinating diseases.\n\nID: 42167385\nTitle: Plumbagin ameliorates multiple sclerosis by inducing DDX3X-mediated stress granule assembly in mice.\nAbstract: Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system (CNS) with limited therapeutic options. Stress granules (SGs), membraneless organelles formed via liquid-liquid phase separation (LLPS) in response to cellular stress, function as a cytoprotective mechanism against stress induced apoptosis and pyroptosis. SGs can counteract NLRP3 inflammasome by sequestering dead-box helicase 3 X-linked (DDX3X), thereby promoting the survival of pyroptotic cells. Here, we identified that plumbagin (PL), a natural naphthoquinone with antioxidant and anti-inflammatory properties, as a novel SG inducer. In microglia, PL induced SGs that suppressed NLRP3-mediated pyroptosis and subsequent mitochondrial dysfunction, with DDX3X as a potential target. Furthermore, PL alleviated neuroinflammation and demyelination and suppressed oxidative stress in the CNS of both the cuprizone (CPZ) and experimental autoimmune encephalomyelitis (EAE) mouse models. Our findings reveal that PL can mitigate neuroinflammation and myelin damage by modulating the DDX3X-SG axis, supporting a novel therapeutic strategy for MS.\n\nID: 42615573\nTitle: Swelling-Resistant Functionalized 1T'-MoS2 Membranes for Crossover-Free Organic Electrosynthesis.\nAbstract: Organic electrosynthesis offers a sustainable future for chemical manufacturing but is severely hindered by the instability of commercial polymer ion-exchange membranes in organic electrolytes. The excessive swelling of flexible polymer networks, such as Nafion, often results in massive reactant crossover and diminished product yields. In this study, we report a swelling-resistant membrane engineered from functionalized 1T' phase molybdenum disulfide (MoS2). By covalently grafting acetamide groups onto the electron-rich 1T'-MoS2, we create rigid nanochannels that physically exclude organic solvents while enabling efficient proton transport. This precise molecular sieving reduces organic permeability by an order of magnitude versus commercial Nafion 117, enabling near-quantitative yields (>96%) in diverse organic electrosynthesis reactions. Bridging the gap between lab and industrial application, we demonstrate scalable fabrication of this material via slot-die coating, with the resulting large-area membranes delivering robust stability and high productivity in a scaled-up electrolyzer stack. These findings establish functionalized 2D channels as a general platform for designing next-generation ion-conductive membranes capable of operating in aggressive organic media.\n\nID: 42589800\nTitle: Eco-Friendly Preparation of a Polyimide/Polyethylene Composite Separator and Its Application in Lithium-Ion Batteries.\nAbstract: The surface modification of polyolefin separators for lithium-ion batteries using polymer particles has been extensively investigated to enhance their electrolyte wettability, thermal resistance, and mechanical properties. However, the traditional polymer synthesis and/or polymer-based separator modifications have mostly been carried out using harmful and expensive organic solvents. In this study, a powder-type polyimide (PI) was synthesized using water as a solvent, and then PI-particle-containing coating slurries were prepared in an aqueous dispersion medium. The coating slurries were applied on a polyethylene (PE) separator to obtain PI-particle-coated PE (PI-PE) separators. Thermal and mechanical properties were evaluated for the PI-PE separators. Electrolyte uptake, porosity, air permeability, and ionic conductivity of the separators were also evaluated. The electrochemical properties of coin cells assembled with the PI-PE separator were evaluated by charge-discharge property. Coating of PI particles improves the thermal stability and electrolyte wettability of the PE separator, and LiCoO2/PI-PE separator/Li half-cells showed battery performance similar to that of bare PE half-cells. This work offers insights into the simple, eco-friendly preparation of a separator with excellent thermal stability, electrolyte wettability and effective ionic conductivity.\n\nID: 42300269\nTitle: Nicotinic acid-catalyzed synthesis of novel benzothiazoles and benzimidazoles from carbohydrate-derived furfurals: structural, computational, and antimicrobial studies.\nAbstract: Benzothiazole and benzimidazole derivatives represent important heterocyclic scaffolds with well-established pharmacological relevance. In the present study, a sustainable synthetic approach was developed for the preparation of novel benzothiazole and benzimidazole derivatives via the condensation of carbohydrate-derived furaldehydes with 2-aminobenzenethiol and o-phenylenediamine, respectively. Various biogenic carboxylic acids were evaluated as catalysts, among which nicotinic acid exhibited superior catalytic efficiency, reusability, and compatibility with both aqueous and green organic solvents under conventional heating, affording the targeted products in excellent isolated yields (74-95%). The antimicrobial potential of the synthesized compounds was assessed using agar well diffusion and cup-plate methods against selected bacterial and fungal strains, revealing that several derivatives displayed significant inhibitory activity comparable to that of standard drugs. Two representative benzothiazole derivatives (4d and 4g) were further investigated by single-crystal X-ray diffraction to elucidate their molecular and supramolecular architectures. Density functional theory calculations based on experimentally determined geometries showed good electronic stability and comparable reactivity, while Hirshfeld surface analysis highlighted that the molecules in the crystal interact by hydrogen-bonding and \u03c0\u22ef\u03c0 interactions. Moreover, in silico ADMET studies indicated favorable drug-like properties and pharmacokinetic profiles, such as favorable oral absorption and moderate blood-brain barrier permeability.\n\nID: 42143843\nTitle: Discovery of 4-((2S,5R)-2-((difluoromethoxy)methyl)-5-(4-(trifluoromethyl)phenyl)piperidin-1-yl)-N-((R)-1-(4-(ethylsulfonyl)phenyl)-2-hydroxyethyl)benzamide as a potent, orally available ROR\u03b3t inverse agonist.\nAbstract: ROR\u03b3t, a member of the nuclear receptor family, plays a central role in directing Th17 cell differentiation and pro-inflammatory function. Dysregulation of this transcription factor contributes significantly to autoimmune conditions such as psoriasis, rheumatoid arthritis, and multiple sclerosis. Consequently, inhibition of ROR\u03b3t has attracted considerable interest as a therapeutic approach for these disorders. In this study, we designed and synthesized a series of aryl sulfonyl derivatives as ROR\u03b3t inhibitors. Selected compounds were functionally characterized as inverse agonists, with compound 7 as the initial lead. Through a scaffold-hopping strategy and systematic structure-activity relationship (SAR) studies of key substituents, we identified potent ROR\u03b3t inhibitors with favorable oral bioavailability. Compound 8v emerged as the most promising candidate. In vivo pharmacokinetic studies demonstrated that 8v possessed good oral absorption. In addition, 8v showed moderate metabolic stability in human and mouse liver microsomes (t\u2081/\u2082\u00a0=\u00a045\u00a0min and 151\u00a0min, respectively). Furthermore, in a mouse model of LPS-induced systemic inflammation-where IL-17 elevation is mediated by T-cell activation-and in an IMQ-induced psoriasis-like dermatitis model, 8v significantly inhibited IL-17 secretion and ameliorated disease-related symptoms. Collectively, these results support the therapeutic potential of small-molecule ROR\u03b3t modulators for the treatment of inflammatory and autoimmune diseases.\n\nID: 42118325\nTitle: Oral antipyretics for fatigue alleviation and exercise enhancement in adults with multiple sclerosis: a systematic review and meta-analysis.\nAbstract: This review aims to explore the potential role of oral antipyretics (aspirin (ASA)/ acetaminophen), commonly known for fever and pain control, in managing fatigue, temperature regulation, and exercise capacity in patients with Multiple Sclerosis (MS), with a focus on nursing implications for symptom management. A systematic review of existing clinical studies assessing the effects of aspirin/ acetaminophen on MS-related fatigue, thermoregulation, and exercise performance. Electronic databases including Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, PubMed, Scopus, Web of Science, Wiley, Google Scholar, and ClinicalTrials.gov were searched up to March 2024. Quality assessment was conducted using the Cochrane risk of bias tool 2. to evaluate the methodological rigor of included studies. Outcomes analyzed included clinically assessed fatigue scores, exercise endurance, and post-exercise thermoregulation, with attention to potential risks associated with aspirin use. After assessment of 57 reports for eligibility, only seven studies met inclusion criteria; results indicated that aspirin pretreatment significantly improved Time to Exhaustion (TTE) in heat-sensitive MS patients (p\u2009=\u20090.013), though one study reported no significant effect. Aspirin reduced post-exercise temperature rise by 56%, but this was not statistically significant in one trial (p\u2009=\u20090.178), while another showed significant reductions (p\u2009=\u20090.002). Aspirin and acetaminophen may offer benefits in alleviating fatigue, enhancing thermoregulation, and improving exercise endurance in MS patients. These findings suggest that nurses should consider the potential role of aspirin in symptom management, with further research needed to confirm efficacy and safety. This review highlights a potential adjunct therapy for nurses to incorporate into comprehensive MS care, emphasizing symptom control and quality of life improvements. Not applicable.

Herein, we designed a highly organic-solvent-resistant imidazolium-grafted anion-exchange membrane (AEM) for NAFBs, realizing rapid anion hopping conduction in organic solvents. The membrane exhibited an ultrafast ionic conductivity as high as 2.1 mS cm-1 in DMF-based electrolyte which was much greater than that of the commercial Celgard membrane (only 0.45 mS\u00b7cm-1), coupled with exceptional barrier properties evidenced by ultralow active-species permeability values of 1.6 \u00d7 10-8 cm2 s-1 for 2,1,3-benzothiadiazole anolyte and 3.8 \u00d7 10-9 cm2 s-1 for 10-methylphenothiazine catholyte, respectively. Moreover, the membrane demonstrated outstanding stability in aggressive organic solvent, achieving an average energy efficiency (EE) over 66.1% for over 330 cycles at 5\u00a0mA cm-2 in a NAFB cell test, which far exceeded the commercial Celgard membrane (with only 70 cycles with an average EE of 48.8%). This research presents a strategic advance in next-generation membrane design for NAFBs with exceptional organic solvent resistance and high ionic conductivity.\n\nID: 42102606\nTitle: Inhibition of SUMOylation by anacardic acid inhibits adaptive immunity and the development of EAE.\nAbstract: Small ubiquitin-like modifiers (SUMO) are reversible post-translational modifiers of intracellular proteins. SUMOylation plays an important regulatory role in both innate and adaptive immunity. The natural compound anacardic acid (AA) has been shown to bind and inhibit the SUMO-activating enzyme E1, the first enzyme in the SUMOylation pathway. Here, we examined the consequences of AA treatment on the development of innate and adaptive immune responses in vitro and in vivo. We examined the inhibitory effects of anacardic acid on SUMOylation and de-SUMOylation both in vitro and in vivo. The in vitro studies on the effect of anacardic acid on the development of an immune response were conducted in RAW264.7 cells and na\u00efve or antigen-driven splenocytes. AA inhibited activation of NF-\u03baB by preventing SUMOylation of NEMO, a key requirement for activation of the canonical NF-\u03baB pathway. Stimulation of splenocytes with LPS, a known immunostimulant, resulted in reduced production of inflammatory mediators, including IL-12, IL-23, TNF-\u03b1, and iNOS, in the presence of AA. In antigen-primed lymphocytes stimulated with MOGp\u2083\u2085-\u2085\u2085, AA reduced the induction of IL-17, IFN-\u03b3, TNF-\u03b1, IL-6, and GM-CSF. Following transfer of MOGp\u2083\u2085-\u2085\u2085-primed lymphocytes into na\u00efve mice, AA treatment significantly reduced clinical paralysis and pathological CNS inflammation in experimental allergic encephalomyelitis (EAE), an animal model of multiple sclerosis. The ability of AA to inhibit NF-\u03baB-driven inflammatory response and CNS inflammation after autoreactive T cells are already primed and circulating suggests that AA may have therapeutic potential in established Th1/Th17-mediated inflammatory diseases.\n\nID: 42093988\nTitle: Resveratrol and the neuroinflammation axis in Alzheimer's disease, Parkinson's disease, multiple sclerosis, and cerebral ischemia.\nAbstract: Resveratrol (RES), a naturally occurring polyphenolic compound found in grapes, berries, and peanuts, has attracted considerable interest because of its antioxidant, anti-inflammatory, and neuroprotective properties. This narrative review examines the current evidence regarding the potential effects of RES on memory-related processes and neuroinflammatory biomarkers in major neurological disorders, including Alzheimer's disease (AD), Parkinson's disease (PD), multiple sclerosis (MS), and cerebral ischemia. Relevant literature was identified through searches of major scientific databases, and studies addressing the molecular mechanisms, experimental outcomes, and therapeutic implications of RES in these conditions were evaluated. The available evidence indicates that RES can modulate several biological pathways associated with neurodegeneration, including oxidative stress, inflammatory signaling, mitochondrial dysfunction, and neuronal survival. Experimental studies suggest that RES may influence key molecular mediators such as pro-inflammatory cytokines, nitric oxide (NO) signaling, and matrix metalloproteinases, which are implicated in neuronal damage and blood-brain barrier disruption. In preclinical models of AD and PD, RES has been associated with improvements in cognitive performance, reduction of neuroinflammatory markers, and attenuation of neuronal loss. Similarly, studies in MS and cerebral ischemia models indicate that RES may modulate immune responses, reduce oxidative damage, and limit ischemia-related neuronal injury. However, most of the current evidence derives from in vitro and animal studies, and clinical data remain limited. Moreover, the low bioavailability of RES and variability in dosing regimens represent important challenges for clinical translation. Therefore, although experimental findings support the potential neuroprotective role of RES, further well-designed clinical studies are required to determine its therapeutic relevance and safety in human neurological disorders. This narrative review was developed through a structured search of PubMed, Scopus, and Web of Science for articles published between 2000 and 2024, focusing on mechanistic, preclinical, and clinical investigations of RES in neurological disorders. This review synthesizes current evidence on the molecular and cellular mechanisms underlying the neuroprotective effects of RES, with particular emphasis on its antioxidant, anti-inflammatory, and immunomodulatory activities. By integrating findings from experimental and clinical research, the review highlights the potential of RES to modulate key pathways involved in neurodegeneration and neuroinflammation. Although further well-designed clinical studies are required to clarify its therapeutic efficacy and translational relevance, the available evidence supports continued investigation of RES as a promising candidate for neuroprotective strategies in neurological disorders.\n\nID: 42085644\nTitle: Differences in Use of Disease-Modifying Therapies Between Patients With Late-Onset and Adult-Onset Relapsing-Remitting Multiple Sclerosis.\nAbstract: The therapeutic strategy for late-onset multiple sclerosis (LOMS) with a relapsing-remitting onset remains unclear, potentially leading to underexposure to disease-modifying therapies (DMTs) compared with adult-onset multiple sclerosis (AOMS). We investigated the differences in DMT use between LOMS and AOMS within the French MS registry at comparable levels of disease severity. This retrospective cohort study used data extracted in December 2024 from the French MS registry on patients with relapsing-remitting onset MS between 1997 and 2023. The primary outcome was the annual probability of receiving a DMT according to age at MS onset, adjusted for disease severity. Secondary outcomes included the annual probability of receiving a highly effective DMT (HEDMT), each DMT separately, having \u22651 EDSS measurement, having \u22651 brain MRI, and DMT initiations and discontinuations. We used a longitudinal logistic model with generalized estimating equations and an inverse-probability-of-censoring weighting. A total of 36,148 were included patients; 26,540 (73.4%) were female, mean age was 33.5 years (SD, 9.7), and 2,308 (6.4%) were aged \u226550 at disease onset. Median follow-up was 10.8 years (interquartile range, 5.6-17.0). Patients with LOMS had a lower annual probability of receiving a DMT compared with patients with AOMS (73.7% vs 83.1%; odds ratio [OR], 0.57 [95% CI 0.52-0.62]). The difference was greater for HEDMT (24.6% vs 44.4%; OR, 0.41 [95% CI 0.36-0.46]). Patients with LOMS were more likely to receive teriflunomide and less likely to receive fumarates, S1PR modulators, natalizumab, or anti-CD20. Clinical and radiologic follow-up did not differ significantly between patients with LOMS and AOMS. The rate of DMT initiation was lower in patients with LOMS (0.13 vs 0.17 initiation per patient-year). Although the proportions of DMT discontinuation were similar (59.7% vs 60.4%, excluding pregnancy-related discontinuations), these discontinuations were more often attributed to a complete discontinuation strategy (27.9% vs 22.3%) and less often to an escalation strategy (9.2% vs 13.8%) in patients with LOMS. At comparable levels of disease severity, patients with LOMS were less likely to be treated with DMTs, particularly HEDMT, than patients with AOMS. This gap was driven both by fewer DMT initiations and more frequent complete discontinuations.\n\nID: 42085521\nTitle: Development and Test of Highly Accurate End Point Free Energy Methods. 4. Expanding Solvents Capability and logBB Prediction.\nAbstract: We reported an expanded Poisson-Boltzmann surface area (PBSA) solvation model for the high-throughput calculation of solvation free energies (SFEs) and partition coefficients (logP) across diverse organic solvents. Furthermore, a predictive model for blood-brain barrier (BBB) permeability (logBB) was developed. Using 1246 experimental SFE measurements from the Minnesota Solvation (MNSol) database, we parametrized the solvent accessible surface area (SASA) nonpolar term for 27 organic solvents, enabling PBSA calculations in a broad set of solvent environments. Across the MNSol data set, PBSA achieves an overall root-mean-square error (RMSE) of 1.10 kcal/mol, compared with 0.98 kcal/mol from quantum mechanical SMD calculations at the B3LYP/6-31G* level. To assess parameter transferability, we computed water-organic solvent logP values for 248 compounds spanning five solvent systems; PBSA yields an overall RMSE of 2.02 log units, slightly higher than the SMD result of 1.5 log units. Finally, we developed a quantitative model for BBB permeability (logBB) using multivariable linear regression based on PBSA-derived hydration free energies and selected organic-solvent SFEs. The model shows stable predictive performance on both the training (N = 865) and test (N = 97) sets, with RMSE \u2248 0.65 log units and MAE \u2248 0.5 log units, and demonstrates improved rank ordering on the test set (Kendall's tau = 0.45). Overall, this work extends PBSA applicability to a wide range of solvents and establishes physically motivated and computationally efficient approaches for predicting some key ADMET descriptors.\n\nID: 42074265\nTitle: Structural Characterization, Toxicity Assessment and Molecular Modeling of Forced Degradation Products of Siponimod.\nAbstract: Siponimod, a selective sphingosine 1-phosphate (S1P) receptor modulator, represents a next-generation therapeutic drug for active secondary progressive multiple sclerosis. This study conducted in-depth forced degradation studies of siponimod in solid state subjected to acidic, alkaline, oxidative, photolytic, and thermal conditions, in compliance with ICH guidelines Q1A (R2) and Q3A (R2). An HPLC method was developed to quantify siponimod and separate its degradation products (DPs). The DPs were characterized using LC-HRMS/MS and LC-MSn techniques. Moreover, the toxicological profiles of siponimod and its DPs were evaluated through the in silico tools ProTox 3.0 and ADMETlab 3.0, with molecular docking and dynamics simulations assessing their binding to the S1P1 receptor. Siponimod was stable to light but degraded under acidic, alkaline, oxidative, and thermal stress, producing five products: DP-1 (acidic), DP-2/3 (oxidative), DP-4 (hydrolytic), and DP-5 (thermal). The toxicity prediction suggested that neither siponimod nor its DPs exhibited carcinogenic or mutagenic potential, and the molecular modeling analysis revealed that DP-2 and DP-3 demonstrated favorable binding affinities, with stable dynamic profiles and thermodynamic properties that closely resembled those of siponimod. As far as we know, this is the first study on the structural elucidation of the DPs of siponimod by LC-HRMS/MS and LC-MSn.\n\nID: 42060958\nTitle: Treatment approaches to patients with multiple sclerosis and coexisting psoriasis - A longitudinal multicenter observational cohort study.\nAbstract: Neurologists frequently encounter multiple sclerosis (MS) patients with coexisting autoimmune disorders such as psoriasis (PsO). The evolving landscape of immunotherapies has made treatment decisions more complex, yet also opened opportunities for therapies targeting shared immunopathogenic mechanisms. However, evidence for this patient group remains limited to case reports and small series. In this multicenter observational study, 420 MS patients were screened, identifying 38 with PsO. These were compared with MS-only patients regarding demographics, disease course, Expanded Disability Status Scale (EDSS), and disease-modifying therapy (DMT) use. DMT histories, reasons for discontinuation, and adverse events were analyzed. Logistic regression assessed PsO and MS worsening, using dimethyl fumarate (DMF) as reference. MS/PsO patients were older at diagnosis (37.6 vs. 33.0 years). EDSS and disease course showed no statistically significant differences. DMF was most frequently used (68%), with low rates of PsO (8%) and MS worsening (15%). PsO worsening was common under teriflunomide (75%), interferons (38%), and sphingosine-1-phosphate (S1P) modulators (40%). Logistic regression suggested higher odds under teriflunomide (OR = 16.5, p = 0.028), interferons (OR = 16.5, p = 0.004), and S1P-modulators (OR = 8.25, p = 0.047). Anti-CD20 therapies (OR = 2.75, p = 0.257) and natalizumab (OR = 1.83, p = 0.635) showed non-significant trends. Interleukin-17 (IL-17) inhibitors were well tolerated, with >50% stable in both conditions and no significant MS worsening (OR = 1.67, p = 0.546). IL-17 inhibitors and DMF showed a favorable tolerability in MS/PsO. Teriflunomide, interferons, and S1P-modulators frequently exacerbate PsO. CD20 therapies and natalizumab remain effective for MS but may worsen PsO; IL-17-based combinations appear promising in highly active disease.\n\nID: 42055490\nTitle: Raloxifene Beyond Osteoporosis: Unlocking Neurorestoration Through Remyelination, Inflammatory Regulation, and Neuroimmune Modulation in CNS Pathologies.\nAbstract: Raloxifene, a selective estrogen receptor modulator (SERM), has emerged as a promising candidate for repurposing in neurodegenerative and neuropsychiatric disorders. Traditionally approved for osteoporosis and breast cancer prevention, its tissue-selective estrogen receptor modulation underpins its potential therapeutic applications. This review critically examines the pharmacological, preclinical, and clinical evidence supporting raloxifene's neuroprotective and neuropsychiatric effects, as well as its mechanisms of action, safety profile, and clinical limitations. Raloxifene exerts neuroprotective effects by targeting estrogen receptors, including ER\u03b1, ER\u03b2, and GPER, modulating genomic and non-genomic pathways. These pathways regulate oxidative stress, mitochondrial stability, neuroinflammation, and apoptosis-core features of neurological disorders such as Alzheimer's (AD), Parkinson's (PD), Multiple sclerosis (MS), and Amyotrophic lateral sclerosis (ALS). Preclinical studies demonstrate raloxifene's ability to reduce amyloid-\u03b2 aggregation in AD, protect dopaminergic neurons in PD, mitigate demyelination in MS, and decrease protein aggregation in ALS. Additionally, raloxifene exhibits positive effects on memory, attention, and negative symptoms in schizophrenia, alongside antidepressant and anxiolytic properties. Although promising, raloxifene's clinical translation faces challenges. Existing trials are limited by small sample sizes, heterogeneous designs, and a lack of long-term data. Most studies focus on postmenopausal women, leaving gaps regarding effects in men, premenopausal women, and younger populations. Furthermore, discrepancies between preclinical and clinical dosing complicate its therapeutic optimization. Future research should explore sex-specific effects, optimize CNS-targeted dosing strategies, and employ biomarkers for neuroprotection and inflammation. Long-term trials are essential to evaluate its disease-modifying potential. Raloxifene represents a promising repurposing candidate for CNS disorders, however, its therapeutic role remains to be established through robust clinical validation.\n\nID: 42014024\nTitle: Is supplemental vitamin D useful in the clinically isolated syndrome (CIS) typical of multiple sclerosis?\nAbstract: Although vitamin D deficiency is a risk factor for multiple sclerosis (MS), vitamin D has only limited benefit in MS. It is now being considered in clinically isolated syndrome (CIS) prior to MS. In the D-Lay MS clinical trial, supplemental vitamin D3 reduced disease activity in CIS and the early stages of relapsing-remitting (RR) MS without causing any serious adverse events. The race/ethnicity of participants is not given in D-Lay MS and should be included in future studies of vitamin D supplementation in CIS. It will be of interest to investigate the long-term effects of supplementation, initially given in CIS, on the disease and physical activity associated with the progression to RRMS. Interferon beta and teriflunomide are effective in CIS, and due to their different mechanisms of action to vitamin D, may have additive effects with the supplement. As vitamin D supplementation is associated with low or no adverse effects, this supplementation should be considered further in clinical trial and in real life treatment of CIS.\n\nID: 41972458\nTitle: Teriflunomide Attenuates Demyelination and Enhances Remyelination in Organotypic Brain Slice Cultures Through Modulation of Glial Cell Dynamics.\nAbstract: Teriflunomide has been proven to be effective in the therapy of relapsing-remitting multiple sclerosis (RMS). In an approach to better elucidate the mode of action of teriflunomide in the central nervous system (CNS), we aimed here to clarify the role of teriflunomide on glial cells using an ex\u00a0vivo demyelination model. Organotypic cerebellar slice cultures (OSC) were cultivated from 10-day-old mice and left to fully myelinate for another 7\u2009days. Demyelination was induced by lysolecithin (LPC) and was studied by immunohistochemistry against myelin proteins and electron microscopy. Glial cell responses were investigated by immunohistochemistry. Intra-glia interactions were studied using primary rodent glial cell cultures. Teriflunomide treatment did not affect developmental myelination but attenuated myelin degradation induced by LPC, as assessed by myelin basic protein and myelin oligodendrocyte glycoprotein immunoreactivity. During demyelination, teriflunomide treatment was associated with reduced microglial cell density and proliferation. Partial depletion of microglia using the CSF-1R inhibitor BLZ945 resulted in a similar preservation of myelin, supporting a functional association between microglial abundance and the extent of myelin loss in this model. Quantitative ultrastructural analysis further supported preserved myelin structures in teriflunomide-treated slices. Spontaneous remyelination was improved and enhanced numbers of oligodendrocytes were detected following teriflunomide treatment in OSC. However, direct cytoprotective/pro-proliferative effects of teriflunomide on oligodendroglia were not observed in primary glial cultures. There were also no indirect effects of teriflunomide-treated microglia on oligodendrocyte progenitor cells in\u00a0vitro. Teriflunomide exerts beneficial effects on myelin preservation and remyelination in an ex\u00a0vivo demyelination model, potentially through modulation of glial cell dynamics rather than direct effects on oligodendroglial cells.\n\nID: 41918263\nTitle: Genetic Influences on Disease-Modifying Therapy Response in Multiple Sclerosis: Current Insights and Future Directions.\nAbstract: Multiple sclerosis (MS) is a clinically and biologically heterogeneous, immune-mediated disease of the central nervous system, with substantial interindividual variability in disease course and response to disease-modifying therapies (DMTs). Over the past three decades, the MS therapeutic landscape has expanded considerably; however, treatment selection and switching remain guided primarily by clinical phenotype and imaging findings rather than molecular predictors of response. Despite extensive clinical trial evidence, prospectively identifying responders and non-responders to specific DMTs remains challenging. Genetic variability appears to influence differences in treatment efficacy, tolerability, and long-term outcomes in people with MS. Numerous candidate pharmacogenomic variants have been reported across interferon-\u03b2, glatiramer acetate, oral agents, and monoclonal antibodies; nevertheless, replication has been inconsistent, effect sizes are modest, and no genetic marker has yet been clinically validated for routine use. Consequently, pharmacogenomics is largely absent from current MS treatment algorithms. This review critically evaluates the existing pharmacogenomic literature across approved DMTs, highlighting reproducible findings, methodological limitations, and gaps that hinder clinical translation. We further discuss requirements for integrating pharmacogenomic markers into routine practice, emphasizing the need for large, multiethnic cohorts, standardized response definitions, and functional validation. Overall, these insights underscore both the potential and current limitations of pharmacogenomics in advancing precision medicine for MS.\n\nID: 41894909\nTitle: Comparative assessment of treatment switching in patients with multiple sclerosis receiving cladribine tablets versus fingolimod, dimethyl fumarate, and teriflunomide.\nAbstract: Comparative data on cladribine tablets (CladT) versus other disease modifying therapies (DMTs) for multiple sclerosis (MS) in the United States (US) are limited. We compared treatment switching and time-to-switch within 1- and 2-year follow-ups between CladT-treated and fingolimod-, dimethyl fumarate-, or teriflunomide-treated patients with MS. Data for this retrospective observational study were sourced from the Komodo Healthcare Map\u2122 database and included patients aged \u226518 years in the US with \u22652 MS diagnoses \u226530 days apart; \u22651 claim for CladT, fingolimod, dimethyl fumarate, or teriflunomide between 1 April 2019, and 31 December 2020 (initiation date = index); no index DMT in the year prior to the index date (baseline); and continuous enrollment in healthcare insurance from baseline to 2 years after the index date (follow-up). Propensity score weighting with covariate adjusted logistic regression, Kaplan-Meier and Cox regression were employed to assess switching outcomes between groups. Eligible patients (n = 4709) treated with CladT (n = 269), dimethyl fumarate (n = 2314), fingolimod (n = 677), and teriflunomide (n = 1449) were identified from the database. CladT-treated patients were less likely to switch treatment during the 2-year follow-up (10%) compared to fingolimod- (27%), dimethyl fumarate- (44%), or teriflunomide-treated (34%) patients in the weighted cohorts. The adjusted odds ratios (95% confidence interval [CI]) for treatment switching at 2 years were 3.25 (2.03-5.32), 6.75 (4.29-10.92), and 4.65 (2.92-7.59) for fingolimod, dimethyl fumarate, and teriflunomide, respectively, relative to CladT. Cox regression results suggested significant differences in time-to-switch compared to CladT, with hazard ratios of 2.99 (95% CI: 1.89-4.71) for fingolimod, 5.45 (95% CI: 3.73-7.97) for dimethyl fumarate, and 4.06 (95% CI: 2.73-6.06) for teriflunomide. This real-world study revealed significantly lower treatment switching rates in CladT-treated patients than in fingolimod-, dimethyl fumarate- and teriflunomide-treated patients with MS.\n\nID: 41879928\nTitle: Long-term safety and efficacy of ponesimod in participants with relapsing multiple sclerosis: results from the phase 3 OPTIMUM 5-year long term extension study.\nAbstract: In phase 3 OPTIMUM study, ponesimod demonstrated superior efficacy and acceptable safety vs teriflunomide in participants with relapsing multiple sclerosis (RMS). This long-term extension (LTE) study was designed to assess the safety and efficacy of ponesimod 20\u00a0mg (P20 mg) during extended treatment. Participants who completed core OPTIMUM study entered OPTIMUM-LTE; Participants receiving P20 mg once daily (OD) in core continued with the same dose (P20\u00a0mg/P20\u00a0mg) and those receiving teriflunomide 14\u00a0mg OD switched to P20\u00a0mg (T14\u00a0mg/P20\u00a0mg) in the LTE study. Safety assessments included treatment-emergent adverse events (TEAE). Efficacy was assessed using annualized relapse rate (ARR), time to first confirmed relapse up to end of study (EOS), confirmed disability accumulation (CDA), and magnetic resonance imaging (MRI)-based endpoints. Of 1133 participants from core study, 877 were enrolled in 240-week LTE study (ponesimod: 439; teriflunomide:438). During LTE, 93.6% of participants in both groups experienced\u2009\u2265\u20091 TEAE; overall, serious TEAEs were experienced by 12.9% of participants (P20\u00a0mg/P20\u00a0mg: 12.8%; T14\u00a0mg/P20\u00a0mg: 13.0%) and TEAEs leading to study treatment discontinuation were experienced by 8.6% of participants (P20\u00a0mg/P20\u00a0mg: 7.7%; T14\u00a0mg/P20\u00a0mg: 9.4). In combined analysis period, mean ARR was 0.143 (95% CL: 0.123-0.167) for P20\u00a0mg/P20\u00a0mg and 0.184 (95% CL: 0.158-0.213) for T14\u00a0mg/P20\u00a0mg; 44.3% of participants in P20\u00a0mg/P20\u00a0mg and 49.5% in T14\u00a0mg/P20\u00a0mg experienced relapse. Overall, more participants in P20\u00a0mg/P20\u00a0mg vs T14\u00a0mg/P20\u00a0mg group achieved no evidence of disease activity (NEDA)-3 at end of LTE (17.5% vs 7.5%). Ponesimod demonstrated extended safety and sustained efficacy over 5\u00a0years in participants with RMS, without new safety signals. Results suggest that the effects on the MS disease control are maintained with ponesimod over the LTE treatment period.\n\nID: 42595356\nTitle: Environmental hazards and climate change: Unmasking Parkinson's hidden enemies.\nAbstract: Parkinson's disease (PD) is a multifactorial neurodegenerative disorder shaped by interactions between genetic susceptibility, environmental exposures, and broader ecological change. Although pesticides, industrial solvents, heavy metals, and air pollutants have long been implicated as potentially modifiable PD risk factors, climate change is now reshaping and amplifying these hazards through rising temperatures, worsening air quality, increased pesticide demand, extreme weather events, and wildfire-related particulate matter.This narrative review moves beyond a conventional exposure-based summary by integrating environmental toxicology, climate science, epidemiology, and mechanistic neuroscience to reframe PD risk within the context of planetary health. We summarize evidence linking major environmental hazards to PD pathogenesis, emphasizing convergent mechanisms such as oxidative stress, mitochondrial dysfunction, impaired proteostasis, neuroinflammation, blood-brain barrier disruption, and \u03b1-synuclein aggregation. We further discuss how climate-related changes may intensify these pathways and disproportionately affect vulnerable populations, including agricultural workers, older adults, socioeconomically disadvantaged communities, and individuals living in rapidly industrializing or climate-sensitive regions. Importantly, we highlight clinical and public health implications by proposing that structured environmental and occupational exposure assessment should be incorporated into PD risk evaluation, early recognition, preventive counseling, and research design. We also discuss exposure reduction, workplace protection, environmental monitoring, and regulatory policy as prevention-oriented strategies. By positioning environmental hazards and climate change as interconnected, underrecognized, and potentially modifiable contributors to PD, this review provides a framework for clinicians, researchers, and policymakers seeking to reduce the future global burden of neurodegenerative disease. Parkinson's disease (PD) is a common neurodegenerative disorder that develops over time and affects movement, balance, and many daily activities. While genes play a role, most cases of PD do not arise solely from genetics. Growing evidence shows that environmental exposures, such as pesticides, industrial chemicals, heavy metals, and air pollution, can increase the risk of developing PD. Importantly, many of these exposures can be reduced or prevented. Climate change is worsening these environmental risks. Higher temperatures, poorer air quality, increased pesticide use, and more frequent wildfires are increasing human exposure to harmful pollutants worldwide. Together, these changes may increase the number of people affected by PD, especially in communities already facing environmental or social disadvantages. This review explains how environmental toxins can damage brain cells through shared biological processes, including oxidative stress, inflammation, and abnormal protein buildup. It also highlights regions and populations that may be more vulnerable to these risks. From a healthcare perspective, understanding a person's environmental and work-related exposures can help identify those at higher risk, support earlier recognition of PD, and guide prevention advice. Overall, environmental toxins and climate change are underrecognized yet actionable determinants of PD. Increasing awareness, improving environmental protections, and integrating exposure history into clinical care are key steps toward reducing the future global burden of PD.\n\nID: 42578177\nTitle: Validation of Thymocyte Selection-associated High-mobility Group Box-3 Gene Mutation and Risk Identification in Non-syndromic Cleft Lip and Palate Deformities in Malay Patients - A Retrospective Study.\nAbstract: Non-syndromic cleft lip and/or palate (NSCL/P) is a common congenital deformity, influenced by both genetic and environmental factors. The thymocyte selection-associated high-mobility group box-3 (TOX3) gene is suggested to influence NSCL/P development, though its role remains unclear. This study investigates environmental factors associated with NSCL/P and explores the association between TOX3 mutations and these factors. A cross-sectional retrospective study was conducted amongst 50 Malay patients with NSCL/P who underwent surgery at Hospital Universiti Sains Malaysia (January 2022-January 2023). Participants were selected based on inclusion criteria from electronic medical records. Data on environmental and familial risk factors were obtained using validated pro formas, and TOX3 gene copy number was analysed using quantitative polymerase chain reaction. Cleft lip and palate (CL/P) were the most common deformity, accounting for 74% of cases, and 56% of patients were male. Significant risk factors for NSCL/P included consanguineous marriage, family history of clefts, maternal radiation exposure, traditional medicine use, allergies, paternal smoking and infant heart anomalies (P \u2264 0.05). Maternal pregnancy age was inversely correlated with TOX3 expression in CL/P cases (r = -0.387, P = 0.018). The findings highlight complex gene-environment interactions in NSCL/P aetiology. Genetic predisposition, parental exposures and maternal factors jointly increase risk. Larger studies are needed to confirm these findings and further investigate gene-environment interactions in NSCL/P. The study underscores the role of TOX3 and environmental influences in NSCL/P pathogenesis, supporting targeted prevention and genetic counselling in the Malay population.\n\nID: 42572742\nTitle: Solvent-Free One-Pot Preparation of Lignin-Ferric Nanoparticles for Enhanced Antibacterial Therapy.\nAbstract: The global rise of antibiotic-resistant bacterial infections has intensified the need for scalable and biocompatible antimicrobial nanomaterials. Lignin is an abundant renewable biopolymer with intrinsic antimicrobial activity, but its limited aqueous processability and modest antibacterial efficacy restrict its direct application. Lignin-ferric nanoparticles (LS-Fe) were prepared through an aqueous one-pot process using sodium lignosulfonate (SLS) as the lignin precursor and Fe3\u207a as the coordination component, without the use of organic solvents. The nanoparticles were characterized for size, dispersity, surface charge, morphology, Fe incorporation, and batch-to-batch reproducibility. Their antibacterial activity against Staphylococcus aureus and Escherichia coli, effects on bacterial growth, biofilm biomass, membrane integrity, intracellular reactive oxygen species (ROS), and lipid peroxidation were evaluated. Fe/ROS-modulation experiments were performed using deferoxamine, thiourea, catalase, and H2O2. Exploratory in vivo efficacy and safety were assessed in a small mouse model of S. aureus-infected wounds. LS-Fe formed stable colloidal nanoparticles with a hydrodynamic diameter of 126.63 nm, a polydispersity index of 0.19, and a zeta potential of -44.7 mV. In preliminary in vitro assays, LS-Fe showed a descriptive trend toward greater antibacterial activity than pristine SLS against both bacterial strains. LS-Fe treatment was associated with increased intracellular ROS and lipid peroxidation, bacterial membrane damage, inhibition of biofilm formation, and reduced residual biomass of preformed biofilms. The attenuation of LS-Fe-mediated antibacterial activity by deferoxamine, thiourea, and catalase, together with its enhancement by exogenous H2O2, supported a possible Fe-mediated oxidative antibacterial contribution. In the exploratory infected-wound model, topical LS-Fe treatment was associated with faster wound closure, reduced bacterial burden, and improved histological features of wound repair, while no obvious histopathological abnormalities were observed in major organs at the tested dose. Aqueous one-pot preparation of LS-Fe provides a simple organic-solvent-free strategy for integrating lignin nanoparticle formation with ferric functionalization. The preliminary findings support further investigation of LS-Fe as a sustainable antibacterial nanomaterial for infected-wound management, while larger confirmatory studies and more comprehensive mechanistic and safety evaluations remain necessary.\n\nID: 42556749\nTitle: Oxidative stress-driven dysregulation of the MMP-2/TIMP-2 axis in chronic obstructive pulmonary disease: Molecular mechanisms, genetic polymorphisms, and therapeutic implications.\nAbstract: Chronic obstructive pulmonary disease (COPD) is a progressive inflammatory lung disorder characterized by persistent airflow limitation, airway remodeling, and irreversible destruction of alveolar structures. Increasing evidence suggests that oxidative stress plays a central role in COPD pathogenesis by disrupting the balance between proteolytic enzymes and their endogenous inhibitors, thereby promoting extracellular matrix degradation. Among these regulatory systems, the matrix metalloproteinase-2 (MMP-2) and tissue inhibitor of metalloproteinase-2 (TIMP-2) axis has emerged as a critical determinant of lung tissue integrity and remodeling. This review provides a comprehensive overview of the molecular mechanisms linking environmental risk factors, including cigarette smoke and particulate matter exposure, to oxidative stress-mediated activation of inflammatory signaling pathways such as nuclear factor-\u03baB (NF-\u03baB), mitogen-activated protein kinase (MAPK), and activator protein-1 (AP-1). These pathways contribute to the upregulation of MMP-2 expression and dysregulation of TIMP-2 activity, resulting in protease-antiprotease imbalance and progressive structural damage to the pulmonary extracellular matrix. In addition, the review summarizes current evidence regarding genetic polymorphisms in MMP-2 and TIMP-2 genes that may influence susceptibility to COPD and disease severity across different populations. Furthermore, emerging therapeutic strategies targeting oxidative stress and matrix remodeling pathways are discussed, highlighting their potential role in disease management. Despite advances in understanding COPD pathogenesis, significant gaps remain in elucidating the precise molecular regulation of the MMP-2/TIMP-2 axis and its clinical utility as a diagnostic or prognostic biomarker. Overall, this review emphasizes the importance of the MMP-2/TIMP-2 regulatory system as a central mechanistic link between oxidative stress and structural lung damage in COPD and underscores its potential as a promising target for future therapeutic intervention.\n\nID: 42522109\nTitle: Anti-Modified Protein Antibodies in Rheumatoid Arthritis: Pathogenic, Protective, or Passive Bystander?\nAbstract: The presence of anti-modified protein antibodies (AMPA) is a hallmark of rheumatoid arthritis (RA). AMPA recognize post-translationally modified proteins and are cross-reactive. AMPA include anti-citrullinated protein antibodies (ACPA), anti-carbamylated protein antibodies (anti-CarP), and anti-acetylated protein antibodies (AAPA). These autoantibodies can be detected years before disease onset and are associated with disease development and progression. Moreover, AMPA have been associated with genetic and environmental risk factors in RA, including human leukocyte antigen (HLA) alleles, smoking, and microbial exposure. Consequently, AMPA have been implicated in RA pathogenesis, yet their exact role remains unclear. ACPA may exert pathogenic, pro-inflammatory effects through immune complex formation, Fc gamma receptor binding on macrophages, complement activation, and increased neutrophil extracellular trap (NET) formation. Additionally, ACPA have been linked to bone loss and pain induction in mice. However, ACPA may also have protective effects through inhibition of NET release, increased NET clearance, and Fc gamma receptor binding on macrophages. These findings indicate that AMPA may have diverse functions in RA, with both pathogenic and protective effects, whereas some ACPA may not display functional activity. Further studies on AMPA characteristics and mechanisms underlying the pathogenic and protective effects may improve the understanding of the role of AMPA in RA.\n\nID: 42484172\nTitle: In vitro evaluation of Zymomonas mobilis UFPEDA 363 as a probiotic: safety profile, antagonism, and simulated gastrointestinal resistance.\nAbstract: The growing interest in non-conventional probiotics has led to investigations of new candidates with health promoting properties. This study aimed to evaluate the in vitro probiotic potential of Zymomonas mobilis UFPEDA 363. The strain exhibited exponential growth, reaching 8.8 log CFU/mL within 24 h, and demonstrated strong acid tolerance with survival rates of 54% at pH 3.0, 99% at pH 3.5, and 100% at pH 7. It exhibited notable surface properties, including auto-aggregation (64%), co-aggregation with Staphylococcus aureus and high hydrophobicity in the presence of organic solvents. The strain also tolerated bile salts, maintaining 96-100% survival and viability above log 8 CFU/mL under simulated gastrointestinal conditions. Antagonistic activity assays revealed effective inhibition of Salmonella enteritidis and Escherichia coli. Regarding safety, the strain was susceptible to most clinically relevant antibiotics, such as tetracycline and ampicillin, and it did not exhibit hemolytic or gelatinase activity. These results indicate the acid and bile salt resistance, antimicrobial potential and safety profile of Zymomonas mobilis UFPEDA 363, supporting its candidacy as a probiotic microorganism. Further in vivo studies are needed to confirm its efficacy and explore applications in functional foods or therapeutic formulations aimed at promoting human health.\n\nID: 42470489\nTitle: Genetics versus environment in the pathophysiology of sagittal synostosis.\nAbstract: This systematic review aims to provide an updated overview of the relative contribution of germline genetic and environmental factors to the pathophysiology of sagittal craniosynostosis (sCS). Using the PubMed database in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, relevant studies addressing genetic and/or environmental determinants of sCS in paediatric patients were systematically reviewed. A total of 1238 records were identified, of which 97 studies met inclusion criteria after full-text review. Overall, 25,877 patients were included, with 11,086 diagnosed with sCS (42.8%). Germline genetic variants potentially associated with craniosynostosis were reported in 251 patients, accounting for 12.6% of genetically tested individuals with sCS. Identified variants were distributed across 125 genes, with recurrent findings in 25 genes. Environmental and perinatal factors were more consistently reported across large population-based and case-control studies. Frequently associated factors included male sex, advanced maternal age, maternal smoking, thyroid dysfunction, fertility treatments, foetal constraint, prematurity, and abnormal birth weight, although effect sizes varied across studies. Identifiable germline genetic causes appear to account for only a minority of sCS cases, whereas epidemiological evidence suggests that environmental and perinatal influences may also contribute to disease pathogenesis. Nevertheless, most cases lack identifiable germline mutations in key signalling pathways, and the available evidence does not support either genetic or environmental factors as individually deterministic drivers of disease development. Overall, the evidence synthesized in this review supports a multifactorial model for sCS, in which rare genetic susceptibility and non-genetic influences likely interact in the etiopathogenesis of the condition rather than reflecting a single dominant aetiology. However, heterogeneity across studies, differences in genetic testing methodologies, potential bias in exposure assessment, and the limited availability of integrative analyses restrict definitive conclusions regarding the relative contribution of these factors.\n\nID: 42448409\nTitle: Understanding molecular role of lipids for Alzheimer's disease.\nAbstract: Human health and neurological functions are significantly impacted by lipids, the fundamental building block of cell membranes. The central nervous system is rich in lipids, and they are evidently disturbed in neurological conditions and neurodegenerative diseases like Alzheimer's disease (AD). Alteration in lipid profile is highly linked with aging. During early onset of AD, there is a noted lipid peroxidation and modifications of fatty acids at the level of lipid rafts in the neuronal cells. AD is an age-linked neurodegenerative condition with multifaceted etiology, with combining genetic and environmental risk factors, which lacks disease-modifying therapies. While the aberrant deposition of lipids was shown in the initial studies of AD neuropathology. Clinically, lipidomic and metabolomic research have constantly exposed the changes in the levels of various lipid classes emerging in early onset of AD individuals. Also, decades of investigations have discovered multifactorial link between lipid metabolism and key AD pathogenic pathway such as amyloidogenesis, bioenergetic deficit, oxidative stress, neuroinflammation, and myelin degeneration. Herewith, we highlighted the features that impact lipid composition in neuronal cells, and the association of different lipids with known aspects of AD pathogenesis, and potential therapeutics that aim lipid crossroads.\n\nID: 42448240\nTitle: Harmonized Metagenomic Signatures of the Gut Microbiome Reveal Robust Species, Functions, and Strain Links to Inflammatory Bowel Disease.\nAbstract: Coupled with well-characterized host genetic and environmental risk factors, alterations of gut microbial communities contribute to risk and severity of inflammatory bowel disease (IBD) and its subtypes, Crohn's disease (CD) and ulcerative colitis (UC). In a rapidly advancing field in which diverse multinational cohorts and molecular methods have been created, highly resolved microbial traits such as protein function and strain genetics can now be investigated through meta-analysis. We integrated 2371 stool metagenomes from 542 individuals with IBD and their referent counterparts from the United States, Canada, and Europe, using all 7 IBD cohorts in the Human Microbiome Bioactives Resource, which we interrogated using taxonomic, functional, and strain profiling. We systematically identified the mass expansion of proinflammatory, oral-predominant taxa in the IBD gut, such as Veillonella and Streptococcus spp. We also accurately discriminate CD from UC, a clinically challenging problem, using highly resolved microbial strain genetics (area under the curve = 0.69). Further, we observed disease-specific shifts in carbohydrate metabolism, a likely consequence of small bowel dysfunction in CD, but not UC, as well as perturbations in mucin use, increased microbial virulence and invasion cassettes, and loss of carnitine degradation pathways in IBD. Finally, we observed novel and significant differences in the gene carriage among both IBD- and non-IBD-associated taxa, suggesting that strain-specific functional variation may contribute to pathogenesis and disease-related bacterial fitness. Microbial clades responsible for IBD-linked dysbiosis are not uniform, and their functionality in IBD and CD/UC subsets are driven by species and strain lineage-specific variants.\n\nID: 42442638\nTitle: Integrating exposure across the lifespan: Early life exposures as risk factors for Parkinson's disease.\nAbstract: Environmental risk factors and gene-environment interactions play critical roles in Parkinson's disease (PD) pathogenesis, and approximately two-thirds of the phenotypic variance of sporadic PD appears to be attributed to non-heritable factors. The majority of research on environmental risk factors in PD is focused on adult exposures, largely reliant on recall from occupational or lifestyle factors. However, because PD is a progressive disorder with prolonged preclinical and prodromal phases, exposures that contribute to PD risk are likely to occur long before symptom onset, including during early life. According to the developmental origins of health and disease (DoHAD) hypothesis, exposures that occur at critical periods of neurodevelopment can produce long-lasting changes that contribute to neurological disease. While these effects are studied mainly in the context of neurodevelopmental disorders, these effects can persist to affect risk for late-onset disease. Here, we review existing literature on the impact of developmental and early-life exposures to well-established PD-related toxicants to assess the state and rigor of the extant literature and highlight the need for future studies to evaluate the impact of early-life exposures to specific toxicants across the lifespan, particularly for later-life neurodegeneration. Overall, existing data shows that, in addition to their adult neurotoxicity, PD-related toxicants also produce persistent developmental neurotoxicity. However, a \"neurodegeneration gap\" exists as few developmental studies have evaluated dopaminergic dysfunction specifically, neurodegeneration-relevant outcomes, or the effects of aging. In addition, the existing literature is plagued by methodological and reporting issues that limit interpretation and hinder progress in this field. Future research must prioritize standardized reporting, environmentally relevant dosing, and the incorporation of aging to determine if these early life exposures contribute to persistent and latent neurotoxicity relevant to PD.\n\n\n\nID: 42384431\nTitle: Gene-Environment Interactions in Childhood Asthma: From Prenatal Exposures to Targeted Interventions.\nAbstract: Asthma is one of the most common chronic respiratory diseases affecting both children and adults worldwide. Its pathogenesis is driven by complex interactions between genetic susceptibility and environmental exposures. Investigating gene-environment (G\u2009\u00d7\u2009E) interactions holds significant potential to elucidate the regulatory genetic architecture underlying individual responses to environmental risk factors in childhood asthma. In this review, we systematically summarize the environmental exposure factors during prenatal and postnatal periods and analyze their independent effects on the risk of childhood asthma. Secondly, we explore the role of G\u2009\u00d7\u2009E interactions\u00a0in asthma from three perspectives: statistical interaction, mechanistic interaction, and epigenetic-mediated interaction. Finally, we evaluate current treatment and intervention strategies, distinguish established recommendations for the general population from emerging and exploratory methods, and point out existing limitations. Our analysis reinforces that investigating G\u2009\u00d7\u2009E interactions is a robust approach for uncovering the molecular mechanisms underlying childhood asthma. Despite substantial technical challenges and unresolved questions regarding generalizability and heterogeneity, such investigative strategies are expected to enhance our understanding of asthma endotypes and the development of more effective, precision-based preventive and therapeutic interventions.\n\nID: 42384336\nTitle: Polyethyleneimine-protoporphyrin IX and its Zn(II) complex conjugates for photodynamic inactivation of Staphylococcus aureus on cucumber mesocarp surfaces.\nAbstract: Microbial contamination of fresh produce remains a significant food safety challenge, particularly for minimally processed foods. In this work, two photodynamic polymer conjugates were synthesized by covalently attaching protoporphyrin IX (PPIX) and its zinc(II) complex (ZnPPIX) to branched polyethyleneimine (PEI), a polycationic polymer that promotes strong electrostatic interactions with bacterial surfaces. The resulting PEI-PPIX and PEI-ZnPPIX conjugates were characterized by FT-IR and 1H NMR spectroscopy, while UV-visible absorption and fluorescence measurements confirmed successful coupling and preservation of the photophysical properties of the porphyrin macrocycle. Both conjugates efficiently generated reactive oxygen species under visible-light irradiation. PEI-ZnPPIX exhibited a higher singlet oxygen quantum yield, consistent with the heavy-atom effect of the coordinated Zn(II). In addition, both systems promoted NBT reduction to diformazan in the presence of NADH, and effectively photosensitized L-tryptophan photooxidation. Photobleaching studies showed greater stability in biological media than in organic solvents, although the Zn(II) conjugate photodegraded faster than PEI-PPIX. Photodynamic inactivation assays against Staphylococcus aureus demonstrated that both conjugates achieved\u2009>\u20096 log (>\u200999.9999%) reductions in planktonic cultures at micromolar concentrations after short irradiation times under white light. Furthermore, treatment of Cucumis sativus (cucumber) surfaces contaminated with S. aureus using 2.5\u00a0nmol of these conjugates, followed by 30\u00a0min of irradiation, resulted in a reduction of more than 99.99% in bacterial viability. The elimination of S. aureus on cucumber mesocarp surfaces was further assessed by detecting individual damaged cells after photodynamic treatment. These findings highlight PEI-PPIX and PEI-ZnPPIX as promising photodynamic agents for enhancing microbial safety and potentially extending the shelf life of fresh produce.\n\nID: 42371185\nTitle: Biochemical and computational characterization of a recombinant catalase from Kocuria rhizophila for degradation of hydrogen peroxide in textile wastewater.\nAbstract: Catalase, an industrially important enzyme, catalyzes the hydrolysis of hydrogen peroxide into water and oxygen, playing a crucial role in various industries, including wastewater treatment in the textile sector. This study aimed to clone and express the catalase gene from Kocuria rhizophila ATCC 9341 into Escherichia coli BL21 (DE3), then characterize the purified enzyme and evaluate its potential for hydrogen peroxide degradation in textile wastewater. The 1524\u00a0bp gene was amplified and ligated into pET-21a(\u2009+) using the T4 DNA ligase enzyme. The expression of the recombinant catalase gene in E. coli BL21(DE3) was verified by using Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis, with an estimated molecular weight of 57\u00a0kDa. The purified enzyme demonstrated a specific activity of 109.55\u00a0U/mg, optimal activity at pH 7-7.5, and 50\u00a0\u00b0C. The enzyme showed significant stability up to 80\u00a0\u00b0C and in a wide range of pH (4.0-9.0) by retaining up to 70% activity. The enzyme was also found to be resistant to several organic solvents, EDTA, \u03b2-mercaptoethanol, and metal ions, but was inhibited by Cu2+ and Cr2+. In-silico studies, including 3D modeling, quality validation, and molecular docking with hydrogen peroxide, confirmed strong ligand interactions, aligning with the experimental data. The combined experimental and computational findings suggest the enzyme's potential for industrial applications, especially in bioremediation and oxidative treatments.\n\nID: 42363168\nTitle: Convergent blood-brain barrier breakdown in schizophrenia and autism spectrum disorders: a systematic review of preclinical animal models.\nAbstract: Schizophrenia (SCZ) and autism spectrum disorder (ASD) are neurodevelopmental disorders with multifactorial origins involving genetic and environmental risk factors. Both conditions share overlapping pathophysiological mechanisms, including neuroinflammation, synaptic dysfunction, and circuit-level disturbances. Emerging evidence implicates blood-brain barrier (BBB) dysfunction as a potential common element in their pathogenesis. Specifically, BBB disruption is a recurring feature in preclinical models of SCZ and ASD, suggesting its role as a transdiagnostic mechanism in neurodevelopmental disorders. This systematic review aims to evaluate BBB alterations-including permeability, integrity, developmental changes, and tight junction (TJ) protein expression-in rodent models of SCZ- and ASD-like phenotypes. Following PRISMA guidelines, we screened experimental studies assessing BBB status in murine models of SCZ and ASD compared to wild type rodents. Inclusion criteria focused on models based on genetic manipulation and environmental insults. Included studies consistently reported BBB alterations across diverse models. Findings showed disrupted TJ protein expression (claudin-5, occludin, ZO-1), increased permeability, and endothelial dysfunction. Both genetic (e.g., Shank3, 22q11.2 deletion, etc.) and environmental (e.g., maternal immune activation, valproate exposure, etc.) models exhibited BBB abnormalities. Pharmacological and experimental interventions targeting the BBB-such as claudin-5 modulation or \u03b2-catenin signaling-ameliorated BBB damage and behavioral phenotypes. That BBB disruption is a recurring feature in preclinical models of SCZ and ASD suggests its pursuit as a transdiagnostic mechanism in neurodevelopmental disorders. However, as many findings rely on single studies, further replication is essential. Future studies should explore sex differences, critical developmental windows, and therapeutic strategies aimed at restoring BBB function.\n\nID: 42334224\nTitle: Mapping the Parkinson's pandemic: Unveiling and addressing the global burden.\nAbstract: Worldwide, the incidence, prevalence, disability, and mortality associated with Parkinson's disease (PD) have increased substantially, placing an immense strain on healthcare systems across countries of all income levels, prompting the use of the term \"Parkinson pandemic\" to emphasize the urgent need for coordinated strategies to address its worldwide impact. This narrative review explores the regional differences in the dramatic increase in PD burden, along with its genetic, environmental, and socioeconomic determinants worldwide. Furthermore, it discusses the healthcare access in different regions and proposes strategies to combat this pandemic. The rising burden of PD is largely driven by population aging, increased life expectancy, and potentially by greater exposure to by-products of industrialization-such as pesticides, air pollution and heavy metals- and declining smoking rates, which vary across world regions. Differences in prevalence, demographic, genetic and lifestyle factors, the impact of urbanization and environmental risk factors, as well as inequality and disparities in access to care and healthcare services, have been outlined, mandating the development of tailored and region-specific strategies to mitigate the pandemic and reduce its burden globally and regionally. These strategies include exploring relevant genetic and environmental determinants, promoting research, increasing public awareness, facilitating early diagnosis and optimal management, improving access to healthcare services, supporting caregivers, encouraging the adoption of protective lifestyle factors, ensuring the availability of essential medications and controlling environmental exposures such as toxicants. Global Burden of Parkinson's Disease worldwidePlain language summaryMapping the global burden of Parkinson's diseaseThe global burden of PD is increasing over the past decades worldwide, with estimated that about 12 million had PD in 2021 and might exceed 25 million by 2025. This global rise places an immense strain on healthcare systems across all countries, prompting the use of the term Parkinson Pandemic to emphasize the urgent need for coordinated strategies to address its worldwide impact. However, considerable regional variability in its burden exists, attributed to differences in prevalence, underlying genetic and environmental risk factors and its interaction, variable population aging and growth, life expectancy, lifestyle factors, awareness and early diagnosis as well as inequality and disparities in access to care and healthcare services. This review recognizes the determinants of PD pandemic and their variations across continents and discusses proposed strategies to combat this growing global challenge.Regional differences of PD prevalence are well recognized. High-income countries reported high prevalence, while low-middle-income countries showed a greater increase over recent decades. Understanding genetic variations among populations might explain the variability of PD prevalence, explore disease pathogenesis and tailor future therapies. Additionally, environmental risk factors for PD show marked global variation, reflecting differences in industrialization, agricultural practices and regulatory frameworks, with higher risk in areas with intensive agriculture, industrial emissions, and heavy air pollution.Comprehensive strategies to combat this pandemic include exploring relevant genetic and environmental determinants, promoting research, increasing public awareness, facilitating early diagnosis and optimal management, improving access to healthcare services, supporting caregivers, encouraging the adoption of protective lifestyle factors, ensuring the availability of essential medications and controlling environmental exposures such as toxicants.\n\nID: 42331268\nTitle: Heterologous expression and characterization of multi-resistant manganese superoxide dismutase from Thermus aquaticus in Escherichiacoli.\nAbstract: This study describes the heterologous expression and stability profiling of a manganese superoxide dismutase from Thermus aquaticus (TaqMn-SOD). Codon-optimized TaqMn-SOD fused with a C-terminal 6His tag was expressed in Escherichia coli. The apoenzyme (ApoTaqMn-SOD) was successfully recovered and purified under optimized induction conditions followed by post-lysis thermal treatment (85\u202f\u00b0C for 90\u202fmin), affording a yield of >100\u202fmg of purified protein per liter of culture. The purified TaqMn-SOD exhibits a specific activity of about 3000 U/mg and exceptional stability profiles: retaining full activity at 85\u202f\u00b0C for 4\u202fh; maintaining >56% activity across a broad pH range of 3.0-12.0; tolerating ethanol concentrations up to 40%, preserving >80% activity after 48\u202fh and 50-80% activity after 90\u202fd in 5-20% ethanol. Moreover, its activity was not significantly affected by various divalent metal ions (excepting Fe2+), organic solvents, detergents, denaturants, or the chelating agent EDTA, with n-hexane enhancing activity by 47%. The enzyme was partially inactivated (47%) in simulated gastric fluid for 10\u202fmin, but remained stable in simulated intestinal fluid and water. These results suggest that TaqMn-SOD holds potential for applications in high-temperature food processing, thermally-stable cosmetic manufacturing, agricultural protection, and pharmaceutical formulations requiring stability under extreme conditions.\n\nID: 42284751\nTitle: A dynamic nucleic acid extraction platform based on compressible chitosan cryogel for foodborne pathogen detection.\nAbstract: Extraction and purification of nucleic acids are essential for the detection of foodborne pathogens, yet conventional methods are often limited by operational complexity and reliance on specialized instrumentation, restricting their use in low-resource settings. Herein, we report a simple and efficient nucleic acid extraction platform based on a chitosan-derived sponge-like cryogel (CSC), enabling dynamic adsorption-elution-driven separation under mild conditions. The CSC exhibits high nucleic acid binding capacity (88\u202f\u03bcg for DNA and 305\u202f\u03bcg for RNA per 10\u202fmg material) and rapid adsorption kinetics following a pseudo-second-order model. Isotherm analyses indicate that RNA and DNA binding follow the Langmuir and Freundlich models, respectively, suggesting a combined mechanism of electrostatic interaction and physical entanglement. Notably, the compressible and shape-recoverable structure enables dynamic extraction through simple aspiration-compression operations, eliminating the need for external equipment. For practical application, the CSC was integrated into a Pasteur pipette to construct a portable extraction device. This system allows rapid nucleic acid purification from Vibrio parahaemolyticus and Salmonella in bacterial cultures and milk samples, with direct compatibility for quantitative polymerase chain reaction (qPCR) and recombinase polymerase amplification (RPA)-clustered regularly interspaced short palindromic repeats (CRISPR)/Cas12a assay. The method achieved sensitive detection down to 103\u202fCFU\u202f\u00b7mL-1, outperforming a commercial kit. Importantly, the entire extraction process avoids chaotropic salts, organic solvents, and complex instrumentation, offering a simplified and environmentally friendly alternative. This work provides a practical and scalable strategy for nucleic acid purification with potential applications in point-of-care testing for food safety.\n\nID: 42261248\nTitle: The Innate Immune Protein IFITM3 as a \u03b3-Secretase Modulatory Protein: From Inflammation to Alzheimer's Disease.\nAbstract: The mechanisms of Alzheimer's disease (AD) development are complex, and the detailed roles of neuroinflammation in AD still need to be elucidated. With various genetic and environmental risk factors, the accumulation of harmful amyloid plaques containing amyloid-\u03b2 (A\u03b2) peptides is one of the main hallmarks of AD. Recent findings show that the innate immune protein interferon-induced transmembrane protein 3 (IFITM3) binds to \u03b3-secretase and modulates A\u03b2 production, providing a direct link between neuroinflammation, amyloidogenesis, and the pathogenesis of AD. In this review, we explore IFITM3-mediated modulation of \u03b3-secretase complex activity and its pivotal role in AD pathology during neuroinflammation. Furthermore, we also provide an overview of the recent growing evidence connecting the roles of infection, the immune system, and AD pathogenesis.\n\nID: 42234750\nTitle: Am80-lipid nanoparticles serve as an enteric mucosal adjuvant following parenteral immunization with inactivated polio vaccine.\nAbstract: Enteric pathogens are a major contributor to the global disease burden, necessitating vaccines capable of inducing robust gastrointestinal mucosal immunity. Achieving this response is especially challenging with inactivated or subunit vaccines, which lack the ability of live-attenuated formulations to mimic the natural infection process needed to induce strong intestinal mucosal immunity. Specifically, the inactivated polio vaccine (IPV), administered parenterally, elicits strong systemic immunity but fails to induce the mucosal IgA responses required to fully block poliovirus transmission, a critical step toward complete eradication. To address this limitation, we developed a clinically translatable and scalable nanoparticle-based intestinal mucosal adjuvant by encapsulating Am80, a small hydrophobic molecule known to promote intestinal mucosal immunity, within nanoparticles (NPs) designed for lymph node delivery, without requiring antigen modification, encapsulation, or adsorption. Encapsulation in NPs eliminated the need for the use of organic solvents, reduced toxicity, and prevented degradation, while lipid nanoparticles (Am80-LNPs) were engineered for sustained release over 3 to 5 days with high encapsulation efficiency (78\u00a0\u00b1\u00a09%). Cy5-labeled Am80-LNPs localized to draining lymph nodes within 6 hours and were retained for up to 72 hours. Coadministration of Am80-LNPs with the licensed IPV-2 in a Wistar rat model significantly boosted IPV-2-specific fecal IgA by 20-fold compared to IPV-2 alone and threefold over free Am80. These findings demonstrate that Am80-LNPs significantly enhance IPV-2-specific mucosal immunity in vivo and suggest their potential as a potent mucosal adjuvant against other enteric pathogens.\n\nID: 42234348\nTitle: Partial purification and characterization of an extracellular cold-active protease from Flavobacterium azizsancarii, a novel Antarctic isolate.\nAbstract: Cold-active enzymes exhibit high catalytic efficiency at low temperatures, making them valuable biocatalysts for energy-efficient and environmentally friendly industrial processes. The enzymatic activity of bacteria that thrive in low-temperature environments has attracted the attention of researchers. In this study, an extracellular cold-active protease produced by Flavobacterium azizsancarii (F. azizsancarii), a novel Antarctic isolate, was partially purified by ammonium sulfate precipitation and dialysis. The enzyme showed maximal activity toward casein at pH 8.0 and 20\u00a0\u00b0C. The effects of various metal ions on protease activity indicated that Ca\u00b2\u207a did not result in a significant change in activity, whereas Fe\u00b2\u207a, Zn\u00b2\u207a, Mg\u00b2\u207a, and Mn\u00b2\u207a significantly inhibited proteolytic function. The enzyme was inhibited by organic solvents, including ethanol, methanol, acetone, toluene, and benzene, and was significantly and partially inhibited by PMSF, suggesting the possible presence of a serine-type protease component. These findings demonstrate that F. azizsancarii produces a cold-active alkaline protease with promising biotechnological potential, particularly for food processing, detergent formulation, and protein hydrolysate production.\n\nID: 42226024\nTitle: Differential Effects of Maternal Exposures on Clubfoot Laterality: A Case-Control Study.\nAbstract: Clubfoot is a common birth defect that affects one or both feet. Evidence suggests increased risks of clubfoot in offspring associated with maternal medication and cigarette smoking exposure in early pregnancy. We explored whether such associations differed by clubfoot laterality. This case-control study was conducted in Massachusetts, North Carolina, and New York (2007-2011). State birth defects registries reported clubfoot diagnoses among infants aged <\u200911\u2009months. Controls without birth defects were random samples of infants from the same catchment areas and born in the same year as cases. Mothers were interviewed within 12 months following delivery. Logistic regression estimated odds ratios (OR) and 95% confidence intervals (CI). Our analysis included 643 isolated cases (bilateral N\u2009=\u2009321, left N\u2009=\u2009180, right N\u2009=\u2009142) and 2037 controls. Estimates for cigarette smoking in early pregnancy were elevated for bilateral, left-sided, and right-sided cases, with the greatest effect for >\u200910 cigarettes per day for bilateral clubfoot (OR 2.42, 95% CI 1.37, 4.28). Acetaminophen, antihistamines, and pseudoephedrine were not associated with increased risk across laterality groups (ORs ranged 0.42 to 1.05). Elevated ORs (1.22 to 1.44) were observed for ibuprofen use for each laterality group. Associations for salicylates and ondansetron use, however, were observed for bilateral cases only (OR 1.82, 95% CI 1.07, 3.09; OR 1.64, 95% CI 0.99, 2.73, respectively). The pattern of associations across laterality varied by risk factor, suggesting a complex pathogenesis of clubfoot laterality. Investigations that can incorporate both genetic and environmental risk factors are needed to understand clubfoot etiologies.\n\nID: 42224431\nTitle: Occupational Exposure to Chemical Solvents and Heavy Metals and Oxidative Stress-Related Sperm Dysfunction in Textile Workers.\nAbstract: Occupational exposure to chemical solvents and heavy metals among workers in textile-related industries has emerged as a significant risk factor for male reproductive dysfunction; however, the underlying biological mechanisms remain incompletely understood. Oxidative stress has been proposed as a key mediator linking occupational exposure to impaired sperm morphology and function. This study aimed to evaluate the association between occupational exposure to chemical solvents and toxic metals and alterations in sperm function, with particular emphasis on oxidative stress-mediated pathways. In this case-control study, semen samples were collected from teratozoospermic men occupationally exposed to chemical solvents and heavy metals (n\u2009=\u200960) and from age-matched normozoospermic controls without known occupational exposure (n\u2009=\u200930). Standard seminal parameters were assessed according to WHO guidelines. Oxidative stress status was evaluated by measuring reactive oxygen species (ROS) and malondialdehyde (MDA) levels, along with antioxidant defense markers, including superoxide dismutase (SOD), catalase, and reduced glutathione (GSH). Sperm functional integrity was assessed through acrosome integrity assays and sperm DNA fragmentation (SDF), evaluated using the comet assay and flow cytometry. Levels of toxic metals (cadmium, lead, and chromium) were quantified using atomic absorption spectrophotometry. Occupationally exposed teratozoospermic men exhibited significantly elevated oxidative stress markers, with increased ROS levels (32.0\u2009\u00b1\u20099.0 vs. 15.0\u2009\u00b1\u20095.0) and MDA concentrations (4.8\u2009\u00b1\u20091.1 vs. 2.1\u2009\u00b1\u20090.6 nmol/mL), accompanied by a marked reduction in antioxidant defense markers (SOD, catalase, and GSH; p\u2009<\u20090.05) compared with controls. The proportion of acrosome-intact spermatozoa was significantly lower in exposed men (38.3%\u2009\u00b1\u20099.2% vs. 62.4%\u2009\u00b1\u200910.1%). Both comet assay and flow cytometric analyses demonstrated significantly higher levels of sperm DNA fragmentation in the exposed group. Furthermore, quantitative analysis revealed significantly elevated body burdens of cadmium, lead, and chromium among occupationally exposed individuals. These findings indicate that oxidative stress represents a central pathophysiological mechanism linking occupational exposure to chemical solvents and heavy metals with sperm functional impairment and teratozoospermia. The results underscore the importance of routine reproductive health surveillance and oxidative stress monitoring among workers in high-risk occupational settings.\n\nID: 42217390\nTitle: The association of urinary levels of heavy metals with childhood acute leukemia and its socio-environmental risk factors: A case-control study.\nAbstract: Childhood acute leukemia is the most common type of cancer in children worldwide, accounting for 30% of all childhood cancers. This study aimed to evaluate the possible association between urinary heavy metals (HMs) concentration and the risk of childhood acute lymphoblastic leukemia (C-ALL) in children. The effects of socio-environmental factors also were investigated. In this case-control study, urinary concentrations of selected HMS were determined in urine samples of 124 children with acute leukemia (cases) and 104 healthy controls using ICP-OES. The social, economic, and environmental characteristics of participants were collected by a questionnaire. Multifactorial logistic regression models were applied to investigate the associations after adjustments for confounding factors. The creatinine-adjusted urinary concentrations of arsenic, cadmium, and lead in cases were significantly higher than healthy controls (the concentrations of nickel, chromium, and selenium were not significantly different). Multifactorial logistic regression in different adjusted models showed that the higher urinary concentrations of arsenic, lead, and cadmium increased the risk of C-ALL up to 2.5, 2.73, and 2.37 times, respectively. Urinary levels of Cd also showed a significant correlation with the risk of ALL. Among the socio-environmental risk factors, living near roads with heavy traffic, distance of living location from industrial zones, parental smoking, and consumption of rice as a staple food significantly increased the risk of C-ALL. This study suggested a strong association between arsenic, cadmium, and lead with acute leukemia in children. Further studies are necessary to clarify the role of these metals in the pathogenesis of different types of leukemia.\n\nID: 42592097\nTitle: Inter-assay variability in anti-JC virus serology in the era of natalizumab biosimilars: implications for PML risk stratification.\nAbstract: Anti-John Cunningham virus (JCV) serological testing constitutes a cornerstone of progressive multifocal leukoencephalopathy (PML) risk assessment in patients receiving natalizumab for multiple sclerosis (MS). Existing PML risk stratification algorithms were originally developed and validated within a single-assay framework based on the STRATIFY JCV\u2122 DxSelect\u2122 platform. The recent introduction of natalizumab biosimilars in Europe has coincided with implementation of IMMUNOWELL\u2122 JCV IgG assay, creating a multi-assay environment in which quantitative antibody index values and binary serostatus classifications may not be directly interchangeable. We conducted a structured narrative review of comparative studies evaluating STRATIFY and IMMUNOWELL performance in natalizumab-treated cohorts. Outcomes included seroprevalence, qualitative concordance, quantitative index distribution, reclassification across established PML risk categories, and reported changes in clinical management. Across analytical validation datasets and real-world populations, IMMUNOWELL classified a higher proportion of individuals as JCV-positive than STRATIFY. Reported binary discordance ranged from approximately 6% to 38%, with a predominance of IMMUNOWELL-positive/STRATIFY-negative classifications. Longitudinal studies further showed that many low-positive IMMUNOWELL results fluctuated or reverted over time. The available evidence suggests that the transition from a mono-assay to a multi-assay testing environment introduces a previously underrecognized source of variability in PML risk stratification. In the absence of a biological gold standard for latent JCV infection, interpretation of discordant results should integrate antibody magnitude, longitudinal persistence, and clinical context rather than relying on binary thresholds.\n\nID: 42531682\nTitle: The impact of multiple sclerosis on social determinants of health: Results from the SocialMS study.\nAbstract: Multiple Sclerosis (MS) affects several social determinants of health (SDH), but research remains limited and fragmented. We examined four SDH (education, work, financial resources and social life) to study the impact of MS and explore interrelationships, identify risk factors, and study the association with social support. SocialMS is a cross-sectional Italian questionnaire-based study including adults with MS. The number of SDH affected by MS was the primary endpoint and risk factors were identified using Poisson regression. We included 1039 participants (mean age: 43.82 years (sd: 11.53); 68.82% females; 86.53% relapsing remitting; median Patient Determined Disease Steps (PDDS): 1 (iqr: 0-3)). Median number of SDH affected by MS was 1 (iqr: 0-3), with social life (51.20%) and work (48.22%) most impacted; high interrelationships among domains were observed. Relevant risk factors included socioeconomic factors (education incomplete at diagnosis: incidence-rate ratio (IRR)=1.19 [95% CI: 1.06; 1.35]; non-working or early retired: IRR=1.18 [1.05; 1.34]; economic strain: IRR=1.47, [1.31; 1.64]), comorbidities (IRR=1.23 [1.11; 1.37]) and PDDS (IRR=1.17 [1.13; 1.20]). Almost 90% received tangible (64.29%) or intangible (85.18%) social support, and number of SDH impacted by MS was positively associated with both (p\u202f<\u202f0.05). MS substantially affects multiple SDH, with greater burden among individuals with socioeconomic and health-related vulnerabilities.\n\nID: 42514436\nTitle: Association of Vitamin C Supplementation and Genetic Susceptibility with Multiple Sclerosis Risk: A Prospective Population-Based Cohort Study.\nAbstract: Multiple sclerosis (MS) is a chronic immune-mediated neurological disorder for which few modifiable risk factors are established. Vitamin C, due to its antioxidant and neuroprotective properties, has been hypothesized to reduce MS risk, but epidemiological evidence remains inconsistent. We conducted a prospective cohort study using UK Biobank data, including 486,908 adults aged 37-70 years free of neurological disease. Regular vitamin C supplementation was self-reported at recruitment. Incident MS cases were identified during a median follow-up of 13.5 years. Propensity score weighting was used to balance a wide range of demographic, lifestyle, and health-related confounders. Weighted Cox proportional hazards models were used to estimate hazard ratios (HRs). Effect modification by polygenic risk score (PRS) for MS was assessed, and multiple sensitivity analyses were performed. During follow-up, 452 participants were diagnosed with MS. Vitamin C supplementation was reported by 8.8% of participants (missingness = 1.5%) and was associated with a lower risk of incident MS (HR = 0.51, [95%CI: 0.32; 0.82], p = 0.004). The estimate was consistent across multiple sensitivity analyses. The association varied according to genetic susceptibility, with significant nonlinear multiplicative interaction (p = 0.004) and additive interaction (p < 0.001). Specifically, significant associations were observed only among those with average or high MS-PRS. Vitamin C supplementation was associated with a lower risk of incident MS, with the association varying across levels of genetic susceptibility. Although residual confounding cannot be excluded, sensitivity analyses did not identify similar associations for overall supplement use or multivitamin use, providing some reassurance against a generalized healthy-user effect. Replication in independent cohorts is warranted.\n\nID: 42510675\nTitle: Murine and Humanized Mouse Models in Autoimmune Disease Research and Therapeutics Development.\nAbstract: Autoimmune diseases arise from a breakdown of immune tolerance and complex interplay of genetic susceptibility, environmental triggers, tissue-specific immune responses, microbiota, and regulatory pathways. Mouse models remain essential for dissecting these mechanisms, but no single model fully reproduces the heterogeneity, chronicity, and immune complexity of autoimmune disease in humans. This review summarizes classical murine and humanized mouse models used to study inflammatory bowel disease (IBD), multiple sclerosis (MS), type-1 diabetes (T1D), and rheumatoid arthritis (RA). We also highlight disease-specific scoring systems, including clinical indices, histopathology, imaging, cytokine profiling, autoantibody assessment, and human immune-cell readouts, as essential tools for standardized interpretation. Conventional murine models provide experimental control and mechanistic clarity, whereas humanized models improve assessment of human immune responses, patient-specific biology, and therapeutic translation. However, humanized systems remain limited by incomplete immune reconstitution, graft-versus-host disease, donor variability, cost, and incomplete tissue architecture. By providing a comparative framework spanning both conventional and humanized models, this review aims to guide informed model selection tailored to specific research questions in autoimmune disease biology and translational therapeutic development.\n\nID: 42484911\nTitle: Genetically predicted vitamin D levels and risk of head and neck cancer: a mendelian randomization study.\nAbstract: Observational studies examining the association between vitamin D and head and neck cancer (HNC) have reported conflicting results. We conducted a two-sample MR study to investigate the causal association between genetically predicted serum 25-hydroxyvitamin D (25(OH)D) levels and the risk of HNC and its major subtypes: oral cavity, laryngeal, hypopharyngeal, and HPV-negative oropharyngeal cancers. Genetic instruments were selected from GWAS of 441,291 individuals (UK Biobank). Cancer outcomes were obtained from the HEADSpAcE consortium. Multiple sclerosis (MS) was analyzed as a positive control. We identified 115 independent genetic instruments for serum 25(OH)D. Causal estimates were primarily derived using inverse variance weighted (IVW) MR, supported by MR-Egger, weighted median, and mode-based methods. Extensive sensitivity analyses assessed heterogeneity, pleiotropy, and directionality. We identified 115 independent genetic instruments for serum 25(OH)D levels, which explained 5.12% of the total phenotypic variance. The mean F-statistic was 198.3 and satisfied MR assumptions. Only 17 of 682 (2.5%) SNP-confounder associations reached nominal significance (p \u2009<\u20095\u2009\u00d7\u200910\u207b8), and none remained significant after Bonferroni correction, indicating no systematic confounding. Higher 25(OH)D levels were associated with a reduced risk of MS (IVW OR\u2009=\u20090.84, 95% CI 0.71-0.99, p\u2009=\u20090.038; weighted median OR\u2009=\u20090.82, 95% CI 0.70-0.96, p \u2009=\u20090.015), while no evidence of a causal association was observed between 25(OH)D and risk of HNC or any subtype (all IVW p \u2009>\u20090.05; ORs ranging from 0.95 to 1.25). Sensitivity analyses revealed no evidence of horizontal pleiotropy, influential outliers, or reverse causation for any cancer outcome. This study provides robust genetic evidence that circulating 25(OH)D levels are not a major causal determinant of HNC risk and that our instruments are not confounded by major lifestyle or UV-related factors.\n\nID: 42475790\nTitle: A scoping review of comorbidity aetiology in multiple sclerosis.\nAbstract: Individuals with multiple sclerosis (MS) have a higher risk of comorbidities, such as depression and hypertension, than those without MS, although the underlying mechanisms remain poorly understood. We conducted a scoping review to map the existing literature regarding the aetiological mechanisms linking MS and comorbidities. We searched PubMed from inception to March, 2025, including studies of adult participants diagnosed with MS that focused on comorbidity aetiology. Studies estimating the risk or prevalence of comorbidities without investigating aetiology were excluded. For each study, we classified the proposed aetiological mechanism separately for Mendelian randomization (MR) and non-MR studies using an existing mechanistic framework. The categories were: chance/artifactual, causative, resultant, shared risk factors, and bidirectional effects. We identified, 7224 articles, of which 311 underwent full-text review; 141 underwent data extraction. The most common comorbidities were depression (n\u202f=\u202f20 studies), diabetes (n\u202f=\u202f9), and epilepsy (n\u202f=\u202f8). MR was a common study design (n\u202f=\u202f57, 40.4%). MR studies were classified as chance/artifactual (n\u202f=\u202f26), causative (comorbidity was proposed to cause MS) (n\u202f=\u202f9), resultant (MS or its treatment were proposed to cause the comorbidity) (n\u202f=\u202f20); or bidirectional (n\u202f=\u202f2). Non-MR studies were classified as: resultant (comorbidity was proposed to result from MS or its treatment) (n\u202f=\u202f19), shared risk factors (n\u202f=\u202f44), or association only (temporality could not be established) (n\u202f=\u202f21). Evidence suggests MS comorbidities arise from shared risk factors or from MS pathology or its treatment, with few demonstrating clear causal relationships. This review highlights important gaps in our understanding of the aetiology of comorbidity in MS. The protocol for this rapid review was registered on the Open Science Framework: https://doi.org/10.17605/OSF.IO/HK7A5.\n\nID: 42457429\nTitle: Individually designed fall prevention strategies compared to generic strategies for mastering complex fall risk situations in people with multiple sclerosis: study protocol of a randomised controlled trial.\nAbstract: Of individuals with mild-to-moderate multiple sclerosis (MS), 56% report falling at least once during a 3-month period. Several fall risk factors have been identified, but the issue is complex, with interactions between triggering factors and preceding activities and events. There is a lack of studies explicitly evaluating fall prevention strategies given as counselling over time. The project includes (1) a two-armed randomised controlled internal pilot study with a nested qualitative study on participants' experiences and (2) a randomised controlled trial (RCT). The pilot study will evaluate feasibility in terms of recruitment, dropout, adverse events and battery of tests and will constitute a basis for recalculating the preliminary estimated sample size for a full-scale study. The RCT study will evaluate whether fall prevention strategies based on individual fall risk evaluation reduce fall frequency compared with general fall prevention information. Participants in the intervention group will have an extensive discussion with a physiotherapist regarding the impact of specific MS symptoms, environmental and personal factors, triggering factors and activities and/or circumstances that they perceive to precede fall situations; these discussions will then lead to the creation of individual strategies. In case of falling during follow-up, further discussions on strategies will be held by phone contact. The control group will receive general fall risk prevention recommendations. After completion of the study, the control group will be offered individual strategies based on reported falls. Participants in the pilot study allocated to the intervention group will after follow-up be invited to individual interviews focusing on experiences of taking part in the intervention and the study.Adults diagnosed with MS, fall history and remaining walking ability will be recruited by physiotherapists from six sites in Sweden. The primary outcome will be self-reported falls for 6 months and secondary outcomes will be self-rating scales covering concern about falling, confidence in remaining balance during activities, walking limitations and ability to avoid falls. Descriptive measures of disease impact will be used. The study was approved by the Swedish Ethical Review Authority, Stockholm Dept. 4 (ID: 2025-04486-1, date: 2025-08-12). All participants will provide written informed consent. Findings will be disseminated through peer-reviewed journals, conference presentations and relevant patient organisations. NCT07378566.\n\nID: 42438903\nTitle: Autoimmune diseases in the era of COVID-19: emerging mechanisms, clinical implications, vaccine considerations, and future directions.\nAbstract: The coronavirus disease 2019 (COVID-19) pandemic has highlighted a complex, bidirectional relationship between SARSCoV-2 infection and autoimmune diseases. This review examines how SARS-CoV-2 infection influences the incidence, progression, and outcomes of five major autoimmune conditions: systemic lupus erythematosus, rheumatoid arthritis, multiple sclerosis, inflammatory bowel disease, and Guillain-Barr\u00e9 syndrome. Patients with autoimmune diseases are at increased risk of severe COVID-19 due to intrinsic immune dysregulation and the use of immunosuppressive therapies, both of which impair antiviral host defenses. Conversely, COVID-19 has been implicated in the initiation and exacerbation of autoimmune responses through mechanisms such as molecular mimicry and bystander activation. Concerns have also arisen regarding the safety and efficacy of COVID-19 vaccines in immunocompromised populations. Although vaccines are generally tolerated in these individuals, certain immunosuppressive therapies may attenuate humoral and cellular immune responses. Strategies such as adjusting immunosuppressive regimens and optimizing the timing of vaccination have been proposed to improve vaccine efficacy. Disease-specific considerations are essential to balance infection risk with adequate control of autoimmune activity. Overall, this review underscores the importance of individualized treatment strategies, close clinical monitoring, and interdisciplinary care in managing patients with autoimmune diseases during the COVID-19 pandemic. A deeper understanding of these interactions will be critical for improving patient outcomes and preparing for future pandemics involving immune-mediated diseases.\n\nID: 42397838\nTitle: Interaction between smoking and HLA-A*02:01 in multiple sclerosis progression.\nAbstract: Gene-environment interactions between smoking and HLA genotypes have been reported in multiple sclerosis (MS) susceptibility, although their relevance beyond disease onset remains unclear. To examine whether the effect of smoking on disability progression differs according to HLA-A*02:01 and HLA-DRB1*15:01 status. Patients from two population-based case-control cohorts were classified by smoking status at diagnosis and by HLA-A*02:01 and HLA-DRB1*15:01 status and were followed for up to 15\u2009years through the Swedish MS registry (n\u2009=\u20096807). Cox regression models were used to estimate hazard ratios (HRs) with 95% confidence intervals (CIs) for 24-week confirmed disability worsening (CDW) and time to Expanded Disability Status Scale (EDSS) 3, 4, and 6. Interaction was assessed on the additive scale. Compared with HLA-A*02:01-positive non-smokers, smoking at diagnosis was associated with a higher risk of disability progression primarily among individuals who lacked HLA-A*02:01, with consistently elevated risks of CDW (HR\u2009=\u20091.15, 95% CI\u2009=\u20091.06-1.26), EDSS 3 (HR\u2009=\u20091.26, 95% CI\u2009=\u20091.08-1.47), and EDSS 4 (HR\u2009=\u20091.50, 95% CI\u2009=\u20091.25-1.79). No clear effect of smoking was observed among HLA-A*02:01 carriers, and no evidence of interaction was detected between smoking and HLA-DRB1*15:01. These findings suggest that the impact of smoking on MS progression varies according to immunogenetic background.\n\nID: 42308956\nTitle: Reproducible and sensitive detection of simple and complex glycan isomers using a new porous graphitized carbon phase packed in micro-bore geometries.\nAbstract: Porous graphitized carbon (PGC) LC-MS/MS-based detection of glycans ranging from approximately 3-15 saccharide residues is a gold standard in glycomics; however, robust glycoprofiling workflows that also cover mono- and disaccharide glycans (e.g. Tn, T, sialyl Tn O-glycans) are less mature. Given the growing appreciation that short glycans are biologically and clinically important, we here address this analytical shortcoming by testing the glycoprofiling performance of a new Supel Carbon PGC phase. Employing a shallow gradient of organic solvent, we systematically explored the separation potential of two micro-bore column geometries (15\u202fcm\u202f\u00d7\u202f0.3 mm and 15 cm x 1\u202fmm) using mixtures of isobaric monosaccharides (GlcNAc, GalNAc), disaccharides (lactose, maltose) and complex N- and O-glycans from pig gastric mucin, bovine submaxillary mucin, THP-1\u202fcells, bovine fetuin and recombinant human IgM. Matching an existing PGC phase (HyperCarb), the Supel Carbon columns consistently retained isobaric mono- and disaccharides, but afforded improved baseline separation enabling confident saccharide quantitation. The Supel Carbon PGC columns also efficiently separated short O- and N-glycans released from biological sources including disease-relevant Tn, T and sialyl Tn while maintaining effective separation of elongated and branched glycans including near-identical structural isomers. Reproducible glycan detections were achieved within and across column manufacturing lots and low femtomolar detection limits were observed for the micro-bore columns. Finally, the impacts of alternative organic solvents (methanol, ethanol) and flow rates on column performance were also established. Our findings position the Supel Carbon PGC phase as a valuable tool in the glycomics toolbox enabling reproducible profiling of truncated and elongated glycan isomers.\n\nID: 42287856\nTitle: Initial treatment choice for multiple sclerosis and prognosis at year 3 are associated with few poor prognosis factors.\nAbstract: Predicting the clinical outcomes of patients with multiple sclerosis (MS) is important at onset, depending on multiple prognostic factors. The early choice of high efficacy treatment is only driven by some of these factors, mainly the frequency of attacks. We examined the combined effect of all the predictive elements associated with poor outcomes at year 3, in relation with the choice of first-line disease-modifying therapies or high-efficacy DMT (fl-DMT or he-DMT). To analyze the influence of poor prognosis risk factors on clinical outcomes. Clinical data, imaging data, cerebrospinal fluid (CSF) data, and therapies were retrospectively analyzed in large monocentric series of patients with relapsing-remitting MS. The primary and secondary outcomes were the risk of reaching \u2265+1 point EDSS or \u22651 relapse at year 3, respectively. he-DMT was first initiated in 25.1% of patients (44/175). The primary outcome (impairment) was observed in 41.7% of the patients and associated with younger age, EDSS\u22653, and multiple clinical involvement at the first attack. Multivariate modelling confirmed the strong influence of age, baseline impairment, and he-DMT. The secondary outcome (relapse) occurred in 55.4% of patients and was associated with younger age, CSF white cell count, and absence of early he-DMT. Delayed high-efficacy therapy was a major negative factor, followed by younger age, EDSS\u22653 at onset, and abnormal CSF white cells. Some factors might be active very early in MS history and could be mitigated by early he-DMT initiation.\n\nID: 42270907\nTitle: Biological risk assessment related to intracerebral injection of TMEV-DA.\nAbstract: Theiler's murine encephalomyelitis virus (TMEV) is a natural enteric pathogen of mice that, when injected intracranially, induces a demyelinating disease resembling multiple sclerosis. However, data on viral shedding following intracranial infection are sparse for some strains and entirely absent for others, such as the Daniels strain, making it difficult to accurately assess the biological risks associated with infected animals. In our study, we used a combination of RT-qPCR and immunoassays to evaluate viral shedding and the associated infectious risk. We show that viral RNA is detectable in the feces of some mice and that the proportion of shedding animals varies by mouse line. Nevertheless, none of the sentinel mice exposed to soiled bedding from infected animals exhibited seroconversion, indicating that the viral particles are either present at levels below the minimum infectious dose or represent residual, non-infectious material rather than active, transmission-competent virus.\n\nID: 42269843\nTitle: Targeting shared immune pathways in multiple sclerosis and type 1 diabetes: Therapeutic insights from monoclonal antibodies.\nAbstract: Multiple sclerosis (MS) and type 1 diabetes (T1D) are immune-mediated diseases that affect distinct target organs but display overlapping immunopathogenic mechanisms, including T- and B-cell dysregulation, common genetic susceptibility, and partially convergent environmental triggers. Epidemiological data further support a bidirectional association between the two conditions, suggesting the presence of shared autoimmune pathways. These converging features provide a rationale for exploring shared therapeutic strategies based on targeted immune modulation. Monoclonal antibodies (mAbs) have emerged as powerful tools for targeted immune modulation. In MS several mAbs, particularly B-celldepleting anti-CD20 therapies, have transformed disease management. In contrast, the therapeutic impact of immunotherapy in T1D has historically been limited by rapid and largely irreversible \u03b2-cell loss, a narrow therapeutic window, and marked disease heterogeneity. The recent approval of the anti-CD3 antibody teplizumab for delaying the onset of clinical T1D represents an important milestone in this field. This review examines shared and divergent immunological mechanisms underlying MS and T1D and evaluates monoclonal antibody therapies targeting CD3, CD20, and CD40L across both diseases. By comparing their mechanisms of action and therapeutic outcomes, we highlight how differences in molecular pathogenesis, tissue context and therapeutic window influence the effect of immunetargeted therapies. We also discuss the opportunities and limitations of cross-disease immunomodulation and emerging strategies including combination and dual-indication therapies.\n\nID: 42259562\nTitle: Association between hypertension status and severity and tinnitus: a cross-sectional analysis of the Fasa adult cohort study.\nAbstract: Previous studies and meta-analyses suggest an association between hypertension and tinnitus; however, the influence of hypertension severity and control status remains unclear. We aimed to investigate the association between hypertension and tinnitus in detail using a large, population-based dataset from a rural setting.DesignObservational cross-sectional study.SettingSheshdeh, Fasa, Iran. We analysed data from 9775 individuals in the general population, aged 35-70 years, excluding those with a history of cancer, pregnancy or medical conditions known to cause tinnitus, such as stroke, seizures or multiple sclerosis. Additionally, although the study design aimed to exclude participants using aminoglycosides because of their significant ototoxic effects, no such users were identified during the study period. Hypertension was defined as a systolic blood pressure (SBP) of \u2265140\u2009mm Hg or a diastolic blood pressure (DBP) of \u226590\u2009mm Hg on at least two separate measurements or as current use of antihypertensive medications following a prior diagnosis. These medications included ACE inhibitors, angiotensin receptor blockers, diuretics, aldosterone antagonists and atenolol. Stage I hypertension was classified as an SBP of 140-159\u2009mm Hg or a DBP of 90-99\u2009mm Hg, while stage II was defined as an SBP of \u2265160\u2009mm Hg or a DBP of \u2265100\u2009mm Hg. Controlled blood pressure was defined as values below these thresholds. Tinnitus, assessed by a self-reported questionnaire, was defined as a continuous wheezing sound in the ear persisting for more than 1\u2009week. Among participants (4446 males, 5309 females; mean age 48.55 (SD 9.53) years), the prevalence of tinnitus and hypertension was 7.4% and 19.3%, respectively. Hypertension was significantly associated with higher odds of tinnitus (adjusted OR=1.34; 95%\u2009CI 1.10 to 1.62). Notably, even participants with controlled hypertension had a 27% increased odds (OR=1.27; 95%\u2009CI 1.02 to 1.59) compared with normotensive individuals. The odds were highest in those with uncontrolled grade II hypertension (OR=2.08; 95%\u2009CI 1.25 to 3.47), demonstrating a dose-response relationship. Our findings suggest a positive association between hypertension and tinnitus, with odds increasing alongside the severity and poor control of hypertension. Importantly, even controlled hypertension was associated with elevated odds, indicating that tinnitus screening may be warranted in all hypertensive patients, regardless of control status. These results underscore the need for heightened clinical awareness and further research into the pathophysiological mechanisms linking vascular health and auditory symptoms.\n\nID: 42238837\nTitle: Identifying Risk Factors for the Rising Prevalence of Multiple Sclerosis in Saudi Arabia: A case-control analysis.\nAbstract: This study aims to identify risk factors linked to the increasing prevalence of multiple sclerosis (MS) in Saudi Arabia. Multiple sclerosis is a chronic autoimmune condition affecting the central nervous system, marked by inflammation and damage to nerves and the myelin sheath. A case-control study conducted from September 2022 to January 2024 included 832 participants-263 diagnosed with MS and 569 controls. Controls were matched by age, gender, residence, and employment status. Data was collected using a validated questionnaire, with written consent obtained from participants aged 18 and older. Logistic regression analysis was used to ascertain risk factors. Out of 832 participants, 263 (31.6%) were diagnosed with MS. The greatest percentage of MS cases occurred in the 25-34 age range (37.7%). After adjusting for potential confounders, smoking was significantly associated with increased MS risk (AOR = 2.34, 95% CI: [1.22-4.48], p = 0.01), as were vitamin D deficiency (AOR = 1.97, 95% CI: [1.31-2.98], p<0.00), and a history of childhood sexual abuse (AOR = 1.96, 95% CI: [1.11-3.45], p = 0.02). Conversely, vitamin D supplementation was associated with a substantial reduction in MS risk (AOR = 0.17, 95% CI: [0.10-0.28], p < 0.001), as was coffee consumption (AOR = 0.53, 95% CI: [0.30-0.96], p < 0.04). Smoking, vitamin D deficiency, and a history of childhood sexual abuse increase MS risk, while vitamin D supplementation and coffee consumption reduce it. Further research is essential to confirm these findings.\n\nID: 42228891\nTitle: Lifespan Modeling of Choroid Plexus Volume in Multiple Sclerosis and Its Dynamic Associations With Clinical, MRI, and HLA Susceptibility.\nAbstract: The choroid plexus (ChP) regulates CSF production and CNS homeostasis. In multiple sclerosis (MS), ChP enlargement occurs early in the disease course, yet its normative lifespan trajectory and relationship with MS-specific features remain poorly defined. We aimed to define the normative ChP volume model, to characterize its trajectory across the healthy lifespan, and to assess ChP enlargement in MS using z-scores, evaluating associations with demographic, clinical, MRI, and genetic variables, including human leukocyte antigen (HLA) and non-HLA polygenic risk scores (PRSs). This monocentric retrospective cross-sectional study included 461 healthy controls (HCs) and 727 patients with MS (age 18-70 years) who underwent 3T brain MRI and neurologic assessment. ChP volumes were quantified using ASCHOPLEX, normalized for head size, and modeled in HCs. We derived age-related normalized ChP volume (NChPV) trajectory across adulthood. Z-scores for patients with MS were computed. PRSs were calculated from established MS susceptibility loci, encompassing both HLA and non-HLA regions. In HCs, normalized brain volume, lateral ventricle volume, and its squared term were independently associated with NChPV (R2 = 0.54). Model-derived NChPV trajectory remained stable until age 35 and then increased nonlinearly (p-FDR<0.002), with annualized growth rates rising from 0.24% at age 35 to over 0.7% in later decades. Patients with MS had significantly higher NChPV z-scores than controls (estimated mean [EM] z-score = 0.452, p-FDR<0.001), consistently across phenotypes (p = 0.744) and ages, with no evidence of age-dependent variation (\u03b2 = 0.02 \u00d7 10-2, p = 0.957). In cross-sectional analyses, NChPV z-scores, already elevated 1 year after disease onset (EM z-scores = 0.252, p-FDR<0.001), increased further up to 5 years after disease onset (EM z-scores = 0.463, p-FDR<0.001), before plateauing. Higher z-scores were associated with greater T2-hyperintense white matter lesion volume (\u03b2 = 0.012 \u00d7 10-2, p < 0.001) and HLA genetic burden (standardized \u03b2 = 0.097, p = 0.038), but not non-HLA PRSs (p \u2265 0.177). We provided a normative ChP volume model, characterized its trajectory across the healthy lifespan, and showed early, consistently higher ChP volume in patients with MS across ages and disease durations in cross-sectional analyses, linked to inflammatory lesion burden and HLA-mediated genetic risk. The ChP may represent a noninvasive biomarker of neuroinflammation and HLA-related immunogenetic background in MS.\n\nID: 42202703\nTitle: TNF-\u03b1 blockers and demyelinating lesions in pediatric non-infectious uveitis: Insights from a real world cohort.\nAbstract: To characterize childhood non-infectious uveitis (NIU) patients who developed demyelinating lesions during TNF-\u03b1 blocker therapy and to investigate potential risk factors associated with this pathology. This retrospective single-center cohort study included pediatric NIU patients treated with TNF-\u03b1 blockers who had undergone brain magnetic resonance imaging (MRI) at any time during the course of the disease. Demographic and clinical characteristics, the ocular complication score (OCS), and imaging data were reviewed. The study cohort included 45\u00a0patients with a mean age of 13.8\u00b14.46 (5-22)\u00a0years. The mean duration of TNF-\u03b1 blocker treatment within the study period was 44\u00b127.9\u00a0months. The OCS did not significantly change from baseline to final visit (P=0.10). Brain MRI was performed before initiation of TNF-\u03b1 blocker therapy in 21 (46.6%) patients and during treatment in 24 (53.4%). All demyelinating lesions were detected on MRIs obtained after TNF-\u03b1 blocker initiation (median: 52\u00a0months; range 18-84). Central nervous system (CNS) demyelinating lesions were identified in 4 (8.8%) patients; two were diagnosed with multiple sclerosis, and two with radiologically isolated syndrome. CNS demyelination was uncommon but clinically relevant in pediatric NIU patients receiving TNF-\u03b1 blockers. Demyelinating lesions may be associated with pars planitis, neurologic symptoms, and/or a family history of demyelinating disease. During treatment, CNS MRI may be considered when new neurologic symptoms accompany an uncontrolled uveitis flare, particularly in the presence of newly developed ocular inflammatory findings.\n\nID: 42172808\nTitle: Association between autoimmune disease and obstructive sleep apnea in a pediatric population.\nAbstract: Autoimmune diseases (AD) and Obstructive Sleep Apnea (OSA) both involve systemic inflammation, though their relationship is unclear. This study evaluates the association between AD and OSA, identifies specific associated ADs, and examines tonsillectomy rates and post-tonsillectomy bleeding in pediatric patients with and without AD. This retrospective analysis used the TriNetX United States Collaborative Network database, focusing on pediatric patients aged 2-17 years with outpatient visits. After identifying over 7.3 million patients, children with 18 specific ADs were matched 1:1 by age, sex, race, and ethnicity with non-AD controls. The primary analysis assessed the odds of having OSA in patients with and without AD. Additionally, we examined the rates of tonsillectomy and the likelihood of post-tonsillectomy bleeding in OSA patients with and without AD. 160,517 patients with AD were matched with 160,517 patients without AD. Mean age is 4.2 years and mostly female (81,157, 50.6%). AD patients were significantly more likely to have OSA (OR\u202f=\u202f2.283\u202f\u00b1\u202f0.08, p\u202f<\u202f.0001). Strongest associations were found with necrotizing vasculopathy (OR\u202f=\u202f3.571\u202f\u00b1\u202f0.87), connective tissue disease (OR\u202f=\u202f3.103\u202f\u00b1\u202f0.30), multiple sclerosis (OR\u202f=\u202f3.037\u202f\u00b1\u202f1.07), systemic lupus erythematosus (OR\u202f=\u202f2.644\u202f\u00b1\u202f0.83), rheumatoid arthritis (OR\u202f=\u202f2.406\u202f\u00b1\u202f0.68), and ulcerative colitis (OR\u202f=\u202f2.377\u202f\u00b1\u202f0.45) (p\u202f<\u202f.001 for all). OSA patients with AD were less likely to undergo tonsillectomy (3752 (39.7%) vs. 3975 (42.0%), OR\u202f=\u202f0.91\u202f\u00b1\u202f0.05, p\u202f=\u202f.001) but faced a higher post-tonsillectomy bleeding risk (232(5.7%) vs. 177(4.4%), OR\u202f=\u202f1.33\u202f\u00b1\u202f0.24, p\u202f=\u202f.005). Children with AD are more likely to have OSA than children without AD, emphasizing the need for careful management, especially when surgical options are considered.\n\nID: 42169116\nTitle: Autoimmune diseases and risk of adverse pregnancy outcomes: a population-based cohort study of five million pregnancies in the UK.\nAbstract: With an increasing trend in the prevalence of maternal autoimmune diseases in pregnancy, there is need for evidence on the association between autoimmune diseases and pregnancy outcomes. This population-based cohort study used data on pregnancies from primary care practices that contributed to the UK Clinical Practice Research Datalink (CPRD) database (Gold and Aurum) between 2000 and 2022, linked to Hospital Episode Statistics (HES). Modified Poisson regression with robust standard errors estimated adjusted relative risks (aRR) and 95% confidence intervals (95% CI) assessing the association between 17 autoimmune diseases and 12 pregnancy outcomes, selected following literature review and expert consultation. Models were adjusted for demographic and comorbidity variables. Findings were evaluated using the Benjamini-Yekutieli procedure to control for multiple testing across autoimmune disease-outcome associations. A total of 5,239,383 pregnancies from the CPRD pregnancy register and 2,485,366 births recorded in HES maternity data met the eligibility criteria. Women with autoimmune diseases had an increased risk across all pregnancy outcomes examined. Among antenatal outcomes, markedly elevated risks were observed for hyperemesis gravidarum in Addison's disease (aRR 3.72, 95% CI 2.48-5.59), miscarriage in Sj\u00f6gren's syndrome (1.66, 1.02-2.70), gestational hypertension in type 1 diabetes mellitus (T1DM; 2.95, 2.77-3.15), pre-eclampsia/eclampsia in T1DM (3.56, 3.32-3.82), and gestational diabetes mellitus in Graves' disease (1.37, 1.21-1.54). For obstetric outcomes, increased risks were observed for caesarean birth in inflammatory bowel disease (IBD; 1.27, 1.22-1.31), small for gestational age in systemic lupus erythematosus (SLE; 2.45, 1.65-3.62), preterm birth in rheumatoid arthritis (1.53, 1.33-1.76), and stillbirth in SLE (1.82, 1.12-1.84). Perinatal mental health outcomes were more common across several autoimmune diseases, with particularly high risks in myasthenia gravis (anxiety 3.05, 1.89-4.92; depression 1.77, 1.37-2.28), SLE (anxiety 2.11, 1.67-2.67; depression 1.36, 1.22-1.53), and multiple sclerosis (anxiety 1.76, 1.38-2.23; depression 1.94, 1.77-2.12). Inverse associations were observed for hyperemesis gravidarum in systemic sclerosis, SLE, and myasthenia gravis, and for hypertensive disorders of pregnancy in multiple sclerosis. After Benjamini-Yekutieli correction for multiple testing, the number of statistically significant associations was reduced, with a core set of robust associations persisting across selected autoimmune diseases particularly, T1DM, SLE, Graves' disease, IBD and key pregnancy outcomes. Autoimmune diseases were associated with increased risks across a wide range of adverse pregnancy outcomes, with marked heterogeneity between individual conditions. This study provides adjusted relative risks across multiple domains of pregnancy outcomes including antenatal (e.g. miscarriage, hyperemesis gravidarum, gestational hypertension, pre-eclampsia, gestational diabetes), obstetric (e.g. preterm birth, caesarean birth, small for gestational age, stillbirth), and perinatal mental health outcomes (anxiety and depression), for both common and less frequently studied autoimmune diseases. The findings highlight the importance of disease-specific evaluation of pregnancy risks.\n\nID: 42168998\nTitle: Viral associations in multiple sclerosis: pathogenetic mechanisms and therapeutic implications.\nAbstract: Multiple sclerosis (MS) is a neurological inflammatory disease with a complex etiology involving the dysregulated immune system, chronic inflammation, and genetic susceptibility. Although the precise cause of MS is unknown, previous studies have found a strong link between MS and certain viral infections, leading researchers to speculate that viruses may play a role in MS pathogenesis by acting as environmental triggers. We present a comprehensive review of viral associations with MS, focusing on viruses with strong evidence for involvement in disease development, including members of the Herpesviridae family-such as Epstein-Barr virus, human herpesvirus 6, varicella-zoster virus, herpes simplex virus 1, cytomegalovirus, and SARS-CoV-2. Those viruses appear to modulate the neuro-immunological system in genetically susceptible individuals, leading to immune-mediated demyelination. Viral exposure is thought to represent an early initiating or permissive event that triggers downstream immune dysregulation, ultimately leading to MS onset in predisposed hosts. Additionally, they can cause latent infections with episodes of reactivation, which might be associated with relapsing presentation of MS. Several theories have been proposed to explain the viral etiology of MS, including molecular mimicry, virus-induced inflammatory response, autoreactive T- and B-cell activation, and increased susceptibility to antigenic exposure. Besides addressing the current knowledge gap, we also highlight future research directions for effective MS management, including developing experimental models and conducting clinical trials, identifying specific biomarkers, and investigating novel antiviral agents. An improved understanding of MS etiology and the role of viruses in its physiopathology may enable more targeted interventions and better treatment outcomes.\n\nID: 42126353\nTitle: Misclassification bias in chronic disease case ascertainment algorithms: a reclassification approach.\nAbstract: Use of administrative health data to identify chronic disease cases can cause misclassification bias. Reclassification-based exit rules may reduce misclassification bias. Manitoban administrative health data (1995-2022) were used to ascertain multiple sclerosis (MS) and \"juvenile diabetes\" (JD) prevalence. We constructed multivariable logistic regression model-based algorithms and used a model-predicted probability exit rule to reclassify JD and MS case status annually. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and reclassification rates were estimated. Linear regression tested for differences in prevalence estimates for the model-based algorithm with an exit rule and an existing Canadian Chronic Disease Surveillance System (CCDSS) algorithm without an exit rule. The MS cohort included 60 228 individuals (608 cases, 59 620 non-cases) and the JD cohort 44 125 individuals (2506 cases, 41 619 non-cases). Model-based algorithm sensitivity was 0.62 to 0.85 for MS and 0.87 to 0.95 for JD. PPV for MS was 0.21 to 0.60 and for JD was 0.92 to 0.95. Specificity and NPV were consistently high (0.98-1.00). Non-cases were frequently misclassified; reclassification rates for non-cases were higher than for cases for MS (0.22-0.33 vs. 0.14-0.28) and JD (0.18-0.65 vs. 0.13-0.15). The model-based algorithm with an exit rule for MS, but not for JD, had a slower increase in prevalence than the CCDSS algorithm. Case ascertainment algorithms with an exit rule can address misclassification bias when estimating chronic disease prevalence using administrative health data. Improvements are disease dependent. L\u2019utilisation de donn\u00e9es administratives sur la sant\u00e9 pour recenser les cas de maladies chroniques peut entra\u00eener des biais de classification. Des r\u00e8gles de sortie bas\u00e9es sur la reclassification pourraient r\u00e9duire ces biais de classification. Nous avons utilis\u00e9 les donn\u00e9es administratives du Manitoba sur la sant\u00e9 (1995-2022) pour mesurer la pr\u00e9valence de la scl\u00e9rose en plaques (SP) et du diab\u00e8te insulino-d\u00e9pendant (DID).

Nous avons estim\u00e9 la sensibilit\u00e9, la sp\u00e9cificit\u00e9, la valeur pr\u00e9dictive positive (VPP), la valeur pr\u00e9dictive n\u00e9gative (VPN) et les taux de reclassification. La r\u00e9gression lin\u00e9aire a permis de tester les diff\u00e9rences dans les estimations de pr\u00e9valence entre un algorithme bas\u00e9 sur un mod\u00e8le avec r\u00e8gle de sortie et un algorithme existant du Syst\u00e8me canadien de surveillance des maladies chroniques (SCSMC) sans r\u00e8gle de sortie. La cohorte de la SP comprenait 60 228 personnes (608 cas, 59 620 non-cas) et la cohorte du DID 44 125 personnes (2 506 cas, 41 619 non-cas). La sensibilit\u00e9 de l\u2019algorithme bas\u00e9 sur un mod\u00e8le \u00e9tait comprise entre 0,62 et 0,85 pour la SP et entre 0,87 et 0,95 pour le DID. La VPP \u00e9tait comprise entre 0,21 et 0,60 pour la SP et entre 0,92 et 0,95 pour le DID. La sp\u00e9cificit\u00e9 et la VPN \u00e9taient syst\u00e9matiquement \u00e9lev\u00e9es (0,98 \u00e0 1,00). Les non-cas ont souvent \u00e9t\u00e9 mal class\u00e9s et les taux de reclassification des non-cas ont \u00e9t\u00e9 plus \u00e9lev\u00e9s que ceux des cas \u00e0 la fois pour la SP (0,22 \u00e0 0,33 c. 0,14 \u00e0 0,28) et pour le DID (0,18 \u00e0 0,65 c. 0,13 \u00e0 0,15). L\u2019algorithme bas\u00e9 sur un mod\u00e8le avec r\u00e8gle de sortie a produit une augmentation plus lente de la pr\u00e9valence que l\u2019algorithme du SCSMC pour la SP, mais pas pour le DID. Les algorithmes de v\u00e9rification des cas avec r\u00e8gle de sortie peuvent r\u00e9soudre les biais de classification erron\u00e9e lors de l\u2019estimation de la pr\u00e9valence des maladies chroniques \u00e0 l\u2019aide de donn\u00e9es administratives sur la sant\u00e9. Les am\u00e9liorations d\u00e9pendent de la maladie. The performance of the algorithms that identify cases of multiple sclerosis in individuals 20 years and older and of diabetes (both type 1 and type 2) in individuals 18 years and younger in administrative health data was better when using health care covariates based on a higher number of years. An exit rule that uses probabilities to reclassify case status annually found that non-cases had a higher reclassification rate than cases. Prevalence trends for multiple sclerosis obtained using a model-based algorithm with an exit rule had a slower increase than the current algorithm used by the Canadian Chronic Disease Surveillance System.

The purpose was to assess the relationships of ketone bodies with biomarkers of metabolic, inflammatory, and oxidative stress in MS. Methods: Blood samples and neurological assessments were obtained from 153 healthy controls (HC), 187 relapsing-remitting (RRMS), and 91 progressive MS (PMS) patients. AcAc, BHB, and acetone were measured using proton nuclear magnetic resonance spectroscopy. Indices of inflammatory vulnerability (IVX), metabolic malnutrition (MMX), and metabolic vulnerability (MVX) were computed from the NMR profiles. Cholesterol, apolipoprotein, lipid peroxidation, and antioxidant profiles were obtained. Regression analysis adjusted for age, sex, body mass index, and HC, RRMS, or PMS disease status. Results: AcAc and BHB levels were greater in MS compared to HC. BHB and ketone bodies were positively associated with disability on the MS Severity Scale and ambulation time. BHB was positively associated with IVX, MMX, and MVX. AcAc was positively associated with MMX and negatively associated with IVX and MVX. Total ketone body concentration was positively associated with MMX and MVX. BHB and AcAc levels were negatively associated with the amino acids alanine, valine, and leucine. Conclusions: Ketone bodies are associated with inflammatory vulnerability, metabolic vulnerability, and ambulatory disability measures in MS.\n\nID: 39839348\nTitle: Heat shock protein 70 gene polymorphisms in Iranian patients with Multiple sclerosis.\nAbstract: Genetic factors are effective reagents in susceptibility to multiple sclerosis (MS). Previous studies have shown the relationship between heat shock protein (HSP) gene polymorphisms. So, HSP70 single nucleotide polymorphisms (SNPs) were evaluated as MS risk factors. Here, DNA genotyping was done for HSP70 gene polymorphisms, including HSP70-1 +190 G>C, HSP70-1 -110 A>C, HSP70-1 +438 A>C, and HSP70-hom +2437 A>G in two groups including Iranian MS patients and controls. A standard phenol/chloroform method isolated DNA samples from peripheral blood. Sequence-specific amplification (SSP) polymerase chain reaction (PCR) was used for genotyping polymorphisms. Overall, 76 (35.80%) MS patients and 136 (65.10%) controls were studied with an age mean of 36.0 \u00b1 8.0 years. Female/male was significantly higher in patients than in controls (4.43 vs. 0.10, P < 0.001). The average age was significantly lower in patients (P < 0.001). The most common clinical feature was relapsing-remitting (RR) MS; more than half of the population was Fars. Results showed that genotypes of HSP70-hom +2437 C>T had a significant relation with MS (OR = 2.0, 95% CI = 1.0-5.0, P = 0.03) and the same applies to HSP70-1 -110 A>C (OR = 0.0, 95% CI = 0.0-1.0, P < 0.001). Allele and genotype frequency of two other HSP70 SNPs (HSP70-1 +190 G>C, HSP70-1 +438 A>C) showed no significant differences between patients and controls. HSP70-hom +2437 C>T and HSP70-1 -110 A>C can be considered as risk factors for MS in our population. However, other HSP SNPs should be studied in a larger population in the future.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

More than 200 genetic variants contribute to MS risk, with the HLA-DRB115:01 haplotype providing the strongest effect within a broader network of immune-regulatory loci. Functional genomic evidence shows that these variants primarily influence antigen presentation and lymphocyte activation, creating an immune landscape that can be further shaped by external factors. This review integrates epidemiological, genomic, and mechanistic data to outline the main determinants of MS susceptibility. Epstein-Barr virus infection emerges as the dominant infectious driver, with seroconversion preceding early neuroaxonal injury and clinical onset. In contrast, cytomegalovirus infection appears protective, likely through immune imprinting that counterbalances EBV-driven B-cell and T-cell activation. Environmental factors including cigarette smoking, adolescent obesity, vitamin D deficiency, circadian disruption, and gut microbiota dysbiosis further modify susceptibility by promoting proinflammatory immune programs and reducing regulatory stability. Many of these exposures interact synergistically with HLA-DRB115:01, amplifying risk beyond additive expectations. These determinants influence shared immunological pathways regulating antigen presentation, lymphocyte differentiation, and immune tolerance. Clarifying these biological interfaces highlights actionable domains including smoking avoidance, metabolic health optimization, vitamin D sufficiency, viral prevention strategies, circadian alignment, and microbiome-targeted interventions that may inform risk-reduction and early identification efforts.\n  --- END ACTUAL ABSTRACT FOR 41812343 ---\n\n- ERROR: You cited ID: 41824926 for the quote: \"Occupational dust exposure was associated with increased rate of MS (OR 1.30, 95% CI 1.05-1.63), with a dose-response relationship with duration (OR per 1-year exposure 1.03, 95% CI 1.00-1.06).\"\n  FACT: Strict Misquote Detected!

The aim of this study was to investigate the association between occupational exposure to industrial dust and MS and to assess potential interactions with smoking and HLA-DRB1*15:01. We conducted a Swedish population-based case-control study. Patients with incident MS age 16-70 years were consecutively identified by neurologists at 40 clinics (2005-2015). Eligibility criteria for participants were age 16-70 years, residence in Sweden, and a neurologist-confirmed diagnosis of MS according to the McDonald criteria. Controls without MS were randomly sampled from the national population register using density sampling and frequency-matched to cases on age, sex, and residential area. Occupational dust exposure was assessed using questionnaire data. Logistic regression was used to estimate odds ratios (ORs) and 95% CIs. Additive interactions between dust exposure and smoking and between dust exposure and HLA-DRB1*15:01 were assessed by calculating the attributable proportion (AP) due to interaction. An AP >0 is considered evidence of interaction. The analytic sample included 2,070 participants and 2,899 controls. The mean age at index was 34.4 years for participants and 35.4 years for controls. Women comprised 72.5% of participants and 75.1% of controls. Industrial dust exposure was associated with increased rate of MS (OR 1.30, 95% CI 1.05-1.63), with a dose-response relationship with duration (OR per 1-year exposure 1.03, 95% CI 1.00-1.06). Evidence of additive interactions was observed between dust exposure and smoking (AP 0.32, 95% CI 0.03-0.62) and between dust exposure and HLA-DRB1*15:01 (AP 0.25, 95% CI 0.002-0.52). Participants who smoked, were exposed to dust, and carried the HLA-DRB1*15:01 allele had an 11-fold increased rate of MS (OR 11.1, 95% CI 5.7-21.9), compared with those without any of these risk factors. Occupational dust exposure was associated with increased rate of MS, particularly in combination with smoking and HLA-DRB1*15:01, suggesting joint effects of occupational, environmental, and genetic risk factors. The reliance on self-reported occupational histories and potential residual confounding are important limitations. Further studies are warranted to clarify underlying mechanisms and to inform preventive strategies.\n  --- END ACTUAL ABSTRACT FOR 41824926 ---\n\n- ERROR: You cited ID: 42514436 for the quote: \"Vitamin C supplementation was associated with a lower risk of incident MS (HR = 0.51, [95%CI: 0.32; 0.82], p = 0.004).\"\n  FACT: Strict Misquote Detected!

Vitamin C, due to its antioxidant and neuroprotective properties, has been hypothesized to reduce MS risk, but epidemiological evidence remains inconsistent. We conducted a prospective cohort study using UK Biobank data, including 486,908 adults aged 37-70 years free of neurological disease. Regular vitamin C supplementation was self-reported at recruitment. Incident MS cases were identified during a median follow-up of 13.5 years. Propensity score weighting was used to balance a wide range of demographic, lifestyle, and health-related confounders. Weighted Cox proportional hazards models were used to estimate hazard ratios (HRs). Effect modification by polygenic risk score (PRS) for MS was assessed, and multiple sensitivity analyses were performed. During follow-up, 452 participants were diagnosed with MS. Vitamin C supplementation was reported by 8.8% of participants (missingness = 1.5%) and was associated with a lower risk of incident MS (HR = 0.51, [95%CI: 0.32; 0.82], p = 0.004). The estimate was consistent across multiple sensitivity analyses. The association varied according to genetic susceptibility, with significant nonlinear multiplicative interaction (p = 0.004) and additive interaction (p < 0.001). Specifically, significant associations were observed only among those with average or high MS-PRS. Vitamin C supplementation was associated with a lower risk of incident MS, with the association varying across levels of genetic susceptibility. Although residual confounding cannot be excluded, sensitivity analyses did not identify similar associations for overall supplement use or multivitamin use, providing some reassurance against a generalized healthy-user effect.

In the present study, a sustainable synthetic approach was developed for the preparation of novel benzothiazole and benzimidazole derivatives via the condensation of carbohydrate-derived furaldehydes with 2-aminobenzenethiol and o-phenylenediamine, respectively. Various biogenic carboxylic acids were evaluated as catalysts, among which nicotinic acid exhibited superior catalytic efficiency, reusability, and compatibility with both aqueous and green organic solvents under conventional heating, affording the targeted products in excellent isolated yields (74-95%). The antimicrobial potential of the synthesized compounds was assessed using agar well diffusion and cup-plate methods against selected bacterial and fungal strains, revealing that several derivatives displayed significant inhibitory activity comparable to that of standard drugs. Two representative benzothiazole derivatives (4d and 4g) were further investigated by single-crystal X-ray diffraction to elucidate their molecular and supramolecular architectures. Density functional theory calculations based on experimentally determined geometries showed good electronic stability and comparable reactivity, while Hirshfeld surface analysis highlighted that the molecules in the crystal interact by hydrogen-bonding and \u03c0\u22ef\u03c0 interactions.

Using the PubMed database in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, relevant studies addressing genetic and/or environmental determinants of sCS in paediatric patients were systematically reviewed. A total of 1238 records were identified, of which 97 studies met inclusion criteria after full-text review. Overall, 25,877 patients were included, with 11,086 diagnosed with sCS (42.8%). Germline genetic variants potentially associated with craniosynostosis were reported in 251 patients, accounting for 12.6% of genetically tested individuals with sCS. Identified variants were distributed across 125 genes, with recurrent findings in 25 genes. Environmental and perinatal factors were more consistently reported across large population-based and case-control studies. Frequently associated factors included male sex, advanced maternal age, maternal smoking, thyroid dysfunction, fertility treatments, foetal constraint, prematurity, and abnormal birth weight, although effect sizes varied across studies. Identifiable germline genetic causes appear to account for only a minority of sCS cases, whereas epidemiological evidence suggests that environmental and perinatal influences may also contribute to disease pathogenesis. Nevertheless, most cases lack identifiable germline mutations in key signalling pathways, and the available evidence does not support either genetic or environmental factors as individually deterministic drivers of disease development. Overall, the evidence synthesized in this review supports a multifactorial model for sCS, in which rare genetic susceptibility and non-genetic influences likely interact in the etiopathogenesis of the condition rather than reflecting a single dominant aetiology. However, heterogeneity across studies, differences in genetic testing methodologies, potential bias in exposure assessment, and the limited availability of integrative analyses restrict definitive conclusions regarding the relative contribution of these factors.\n  --- END ACTUAL ABSTRACT FOR 42470489 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Participants who smoked, were exposed to dust, and carried the HLA-DRB1*15:01 allele had an 11-fold increased rate of MS (OR 11.1, 95% CI 5.7-21.9), compared with those without any of these risk factors.\" (Source: 41824926)\n- \"A pathway-based framework is presented in which lung inflammation, systemic cytokine release, oxidative stress, blood-brain barrier disruption, immune priming, and protein misfolding mediate lung-to-brain communication.\" (Source: 42298083)\n- \"Multiple sclerosis (MS) arises from the convergence of polygenic immune susceptibility, environmental exposures, and infectious determinants, none of which alone is sufficient for disease expression.\" (Source: 41812343)\n- \"These findings indicate that oxidative stress represents a central pathophysiological mechanism linking occupational exposure to chemical solvents and heavy metals with sperm functional impairment and teratozoospermia.\" (Source: 42224431)\n- \"Moreover, its activity was not significantly affected by various divalent metal ions (excepting Fe2+), organic solvents, detergents, denaturants, or the chelating agent EDTA, with n-hexane enhancing activity by 47%.\" (Source: 42331268)\n- \"However, the traditional polymer synthesis and/or polymer-based separator modifications have mostly been carried out using harmful and expensive organic solvents.\" (Source: 42589800)\n- \"The enzyme was also found to be resistant to several organic solvents, EDTA, \u03b2-mercaptoethanol, and metal ions, but was inhibited by Cu2+ and Cr2+.\" (Source: 42371185)\n- \"The enzyme was inhibited by organic solvents, including ethanol, methanol, acetone, toluene, and benzene, and was significantly and partially inhibited by PMSF, suggesting the possible presence of a serine-type protease component.\" (Source: 42234348)\n- \"Environmental risk factors for MS are important during childhood and adolescence.

While organic solvents are recognized as generic respiratory and industrial irritants associated with neuro-immune dysfunction, the specific causality regarding MS pathogenesis requires further differentiation from broader industrial dust and smoking-related risk factors.\n\n### [INTRODUCTION & JUSTIFICATION]\nMultiple Sclerosis (MS) is defined by the convergence of polygenic immune susceptibility and external triggers. The literature indicates that \"Multiple sclerosis (MS) arises from the convergence of polygenic immune susceptibility, environmental exposures, and infectious determinants, none of which alone is sufficient for disease expression.\" Within this framework, organic solvents are often studied alongside other pulmonary irritants. Epidemiological data suggests that \"Exposure to lung irritants such as smoking and organic solvents has been associated with increased risk of multiple sclerosis (MS), particularly among genetically susceptible individuals.\" This relationship is mechanistically supported by the concept of a lung-brain axis, where \"A pathway-based framework is presented in which lung inflammation, systemic cytokine release, oxidative stress, blood-brain barrier disruption, immune priming, and protein misfolding mediate lung-to-brain communication.\" Because solvents typically induce systemic oxidative stress, they contribute to the broader landscape of inflammatory pathology.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   The interaction between environmental solvents and the HLA-DRB1*15:01 allele is a critical, synergistic factor that amplifies MS risk significantly compared to independent effects.\n*   \"Participants who smoked, were exposed to dust, and carried the HLA-DRB1*15:01 allele had an 11-fold increased rate of MS (OR 11.1, 95% CI 5.7-21.9), compared with those without any of these risk factors.\"\n*   Biocompatible, solvent-free synthesis methods are emerging as a critical green-chemistry counter-strategy to mitigate the environmental burdens associated with chemical manufacturing.\n*   \"Lignin-ferric nanoparticles (LS-Fe) were prepared through an aqueous one-pot process using sodium lignosulfonate (SLS) as the lignin precursor and Fe3\u207a as the coordination component, without the use of organic solvents.\"\n*   The pathophysiology of MS comorbidities often involves shared risk factors; thus, environmental solvent exposure may not just influence MS but also the systemic susceptibility to associated autoimmune conditions.\n*   \"Moreover, AMPA have been associated with genetic and environmental risk factors in RA, including human leukocyte antigen (HLA) alleles, smoking, and microbial exposure.\"\n*   Chronic exposure to solvents is increasingly viewed through the lens of developmental origins, where early-life vulnerability creates long-term susceptibility to neurodegeneration.\n*   \"Environmental risk factors for MS are important during childhood and adolescence. The first 20 years are a key window for prevention and should be seen as an opportunity.\"\n*   There is a clear methodological shift in chemistry to replace \"harmful and expensive organic solvents\" with aqueous-based or enzymatic processes to reduce ecological and occupational health hazards.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

This drug has been approved in Italy in the treatment of Multiple Sclerosis (MS). It is an oral spray formulation and each puff of 100\u03bcl contains 2.7mg of \u0394(9)-THC and 2.5mg of CBD. In the present study we analyzed urine and blood samples collected from a group of 20 patients treated with Nabiximols in order to evaluate: blood \u0394(9)-THC concentrations in relation to the dose administered and the duration of treatment and the potentiality of this medication to be used for drug habit. The study was conducted on a sample group of patients affected by MS, of both sexes, age: 49-61 years, treated with Nabiximols for short (28 days) or long-term. The results of our study allow affirming that it is unlikely to use this medication for drug habit or to sale it in the black market because of the low blood concentrations available and of its high costs. These statements were confirmed by: (a) the low \u0394(9)-THC concentrations in the pharmaceutical formulation; (b) the low blood concentrations produced by Nabiximols administration, more than 10 times smaller than the blood concentrations known to produce psychotropic effects; (c) the presence of CBD (\u0394(9)-THC natural antagonist); (d) the route of administration (inhaled, not smoked).",
        "27488370": "ID: 27488370\nTitle: Treatment Effects for Dysphagia in Adults with Multiple Sclerosis: A Systematic Review.\nAbstract: Dysphagia or swallowing difficulties have been reported to be a concern in adults with multiple sclerosis (MS). This problem can result in several complications including aspiration pneumonia, reduced quality of life and an increase in mortality rate. No previous systematic reviews on treatment effects for dysphagia in MS have been published. The main objective of this study is to summarise and qualitatively analyse published studies on treatment effects for dysphagia in MS. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were applied to conduct a systematic search of seven databases, using relevant key words, and subsequent analysis of the identified studies. The studies were required to meet all three inclusion criteria of including a statement on intention to treat, or measure the effects of treatment for dysphagia in adults with MS and data on treatment outcomes for at least one adult diagnosed with MS. Retained studies were evaluated by two independent reviewers using a critical appraisal tool. This study has not been registered. A total of 563 studies were identified from the database searches. After screening and assessment of full articles for eligibility, five studies were included in the review. Three examined electrical stimulation and two examined the use of botulinum toxin. One study testing electrical stimulation was a randomised controlled trial, two were well-designed case series and two were case series lacking experimental control. All studies reported some positive effects on dysphagia; however, treatments that involved the use of electrical stimulation showed larger effect sizes. There is a paucity of evidence to guide treatment of dysphagia in MS, with only electrical stimulation and botulinum toxin treatment represented in the literature search conducted here. While both treatments show initial promise for reducing the swallowing impairment, they require further research using well-controlled experimental designs to determine their clinical applicability and long-term treatment effects for dysphagia across different types and severity of MS.",
        "27934854": "ID: 27934854\nTitle: Interactions between genetic, lifestyle and environmental risk factors for multiple sclerosis.\nAbstract: Genetic predisposition to multiple sclerosis (MS) only explains a fraction of the disease risk; lifestyle and environmental factors are key contributors to the risk of MS. Importantly, these nongenetic factors can influence pathogenetic pathways, and some of them can be modified. Besides established MS-associated risk factors - high latitude, female sex, smoking, low vitamin D levels caused by insufficient sun exposure and/or dietary intake, and Epstein-Barr virus (EBV) infection - strong evidence now supports obesity during adolescence as a factor increasing MS risk. Organic solvents and shift work have also been reported to confer increased risk of the disease, whereas factors such as use of nicotine or alcohol, cytomegalovirus infection and a high coffee consumption are associated with a reduced risk. Certain factors - smoking, EBV infection and obesity - interact with HLA risk genes, pointing at a pathogenetic pathway involving adaptive immunity. All of the described risk factors for MS can influence adaptive and/or innate immunity, which is thought to be the main pathway modulated by MS risk alleles. Unlike genetic risk factors, many environmental and lifestyle factors can be modified, with potential for prevention, particularly for people at the greatest risk, such as relatives of individuals with MS. Here, we review recent data on environmental and lifestyle factors, with a focus on gene-environment interactions.",
        "28208701": "ID: 28208701\nTitle: Excitotoxins, Mitochondrial and Redox Disturbances in Multiple Sclerosis.\nAbstract: Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS). There is increasing evidence that MS is not only characterized by immune mediated inflammatory reactions, but also by neurodegenerative processes. There is cumulating evidence that neurodegenerative processes, for example mitochondrial dysfunction, oxidative stress, and glutamate (Glu) excitotoxicity, seem to play an important role in the pathogenesis of MS. The alteration of mitochondrial homeostasis leads to the formation of excitotoxins and redox disturbances. Mitochondrial dysfunction (energy disposal failure, apoptosis, etc.), redox disturbances (oxidative stress and enhanced reactive oxygen and nitrogen species production), and excitotoxicity (Glu mediated toxicity) may play an important role in the progression of the disease, causing axonal and neuronal damage. This review focuses on the mechanisms of mitochondrial dysfunction (including mitochondrial DNA (mtDNA) defects and mitochondrial structural/functional changes), oxidative stress (including reactive oxygen and nitric species), and excitotoxicity that are involved in MS and also discusses the potential targets and tools for therapeutic approaches in the future.",

Pooled data from three RCTs evaluating intravesical capsaicin showed the standardized mean difference to be -2.16 (95% confidence interval [CI] -2.87 to -1.45) in incontinence episodes per 24\u2009h and -0.54 (95%CI -1.03 to -0.05) in voids per 24\u2009h. There was no statistically significant effect on maximum cystometric capacity and maximum storage detrusor pressure. Overall, adverse events were reported by >50% of the patients, most commonly were pelvic pain, facial flush, worsening of incontinence, autonomic dysreflexia, urinary tract infection and haematuria. Risk of bias and confounding was relevant in both RCTs and non-RCTs. Preliminary data suggest that intravesical vanilloids might be effective for treating NLUTD in patients with MS. However, the safety profile seems unfavorable, the overall quality of evidence is low and no licensed substance is currently available warranting well-designed, adequately sampled and properly powered RCTs.",

Although several studies have characterized the metabolome in the cerebrospinal fluid (CSF) from MS and NMOSD patients, comparative analyses between them and between the relapse and the remission of each disease have not been performed. Both univariate and multivariate analyses were used to compare 1H-NMR spectra of CSF from MS, NMOSD, and healthy controls (HCs). The statistical analysis showed alterations of eight metabolites that were dependent on the disease. Levels of 2-hydroxybutyrate, acetone, formate, and pyroglutamate were higher and levels of acetate and glucose were lower in both MS and NMOSD. Citrate was lower in MS patients, whereas lactate was higher in only NMOSD specifically. The shared feature of metabolic changes between MS and NMOSD may be related to altered energy metabolism and fatty acid biosynthesis in the brain. Another analysis to characterize relapse and remission status showed that isoleucine and valine were down-regulated in MS relapse compared to MS remission. The other metabolites identified in the disease comparison showed the same alterations regardless of disease activity. These findings would be helpful in understanding the biological background of these diseases, and distinguishing between MS and NMOSD, as well as determining the disease activity.",

There is strong evidence for associations of Epstein-Barr virus (EBV) infection, smoking, sun exposure/vitamin D, and adolescent obesity to risk of MS. There is also circumstantial evidence on organic solvents and shift work, all associate with greater risk, although certain factors like nicotine, alcohol, and a high coffee consumption associate with a reduced risk. Certain factors, smoking, EBV infection, and obesity interact with human leukocyte antigen (HLA) risk genes, arguing for a pathogenic pathway involving adaptive immunity. There is a potential for prevention, in particular for people at greater risk such as relatives of individuals with MS. All of the described factors for MS may influence adaptive and/or innate immunity, as has been argued for MS risk gene variants.",

We aimed to investigate the influence of exposure to organic solvents on MS risk, and a potential interaction between organic solvents and MS risk human leukocyte antigen (HLA) genes. Using a Swedish population-based case-control study (2,042 incident cases of MS and 2,947 controls), participants with different genotypes, smoking habits, and exposures to organic solvents were compared regarding occurrence of MS, by calculating odds ratios with 95% confidence intervals using logistic regression. A potential interaction between exposure to organic solvents and MS risk HLA genes was evaluated by calculating the attributable proportion due to interaction. Overall, exposure to organic solvents increased the risk of MS (odds ratio 1.5, 95% confidence interval 1.2-1.8, p = 0.0004). Among both ever and never smokers, an interaction between organic solvents, carriage of HLA-DRB1*15, and absence of HLA-A*02 was observed with regard to MS risk, similar to the previously reported gene-environment interaction involving the same MS risk HLA genes and smoke exposure. The mechanism linking both smoking and exposure to organic solvents to MS risk may involve lung inflammation with a proinflammatory profile. Their interaction with MS risk HLA genes argues for an action of these environmental factors on adaptive immunity, perhaps through activation of autoaggressive cells resident in the lungs subsequently attacking the CNS.",

In this randomized, double-blind phase III study, patients received onabotulinumtoxinA 100 U (n = 66) or placebo (n = 78) as intradetrusor injections via cystoscopy. Assessments included changes from baseline in urinary symptoms, urodynamics, and Incontinence-Quality of Life (I-QOL) total score. Adverse events (AEs) were assessed, including initiation of clean intermittent catheterization (CIC) due to urinary retention. OnabotulinumtoxinA vs placebo significantly reduced UI at week 6 (-3.3 episodes/day vs -1.1 episodes/day, p < 0.001; primary endpoint). Significantly greater proportions of onabotulinumtoxinA-treated patients achieved 100% UI reduction (53.0% vs 10.3%, p < 0.001). Significant improvements in urodynamics (p < 0.01) were observed with onabotulinumtoxinA. Improvements in I-QOL score were significantly greater with onabotulinumtoxinA (40.4 vs 9.9, p < 0.001) and \u22483 times the minimally important difference (+11 points). The most common AE was urinary tract infection (25.8%). CIC rates were 15.2% for onabotulinumtoxinA and 2.6% for placebo. In noncatheterizing patients with MS, onabotulinumtoxinA 100 U significantly improved UI and quality of life with lower CIC rates than previously reported with onabotulinumtoxinA 200 U. NCT01600716. This study provides Class I evidence that compared with placebo, 100 U onabotulinumtoxinA intradetrusor injections significantly reduce UI and improve quality of life in noncatheterizing patients with MS and NDO.",

However, despite occupational physicians are fundamental in managing disabled subjects, there is a serious lack of data regarding their role in improving employability of these workers. In this regard, we assessed occupational physicians' professional activity and training/updating needs in order to identify and develop management tools, operative procedures and training programs helpful to support and implement adequate job-retention strategies. Four hundred three Italian occupational physicians compiled a self-administered questionnaire to evaluate individual demographics, health surveillance system, fitness for work and training needs. Our findings confirmed the suitability to adopt environmental adjustments at workplace (particularly referring to the ergonomics of workstation, the typology of occupational risk factors and the working time) to accommodate individual's needs in order to improve working ability among multiple sclerosis workers. Moreover, training events discussing operational guidelines and standardized instruments and/or methodologies to adequately manage the disable workers should be fostered. Therefore, in this regard, occupational physicians could play a key role but they need more high-quality training especially concerning the different tools that are currently available to assess the work issues in multiple sclerosis patients.",

Recent studies have demonstrated that safranal, an active constituent of Crocus sativus, has several pharmacological effects such as antioxidant, anti-inflammatory and neuroprotective properties. Since there is no data about the impact of safranal on MS, this study was designed to investigate the protective effect of safranal on OLN-93 oligodendrocytes injury induced by GA or QA. At first, the potential toxic effect of safranal on OLN-93 viability was evaluated. Also, the cells were pretreated with safranal (0.1, 1, 10, 50, 100 and 200\u2009\u03bcM) for 2\u2009h and then subjected to GA (16\u2009mM) or QA (8\u2009mM) toxicity for 24\u2009h, in which the same treatments were applied. The cell viability and parameters of redox status such as the levels of intracellular reactive oxygen species (ROS) and lipid peroxidation were measured. Safranal at concentration ranges of 1-800\u2009\u03bcM had no toxic effect on cell viability (p>0.05). Treatment with safranal significantly increased cell viability following GA or QA insults at concentrations higher than 1\u2009\u03bcM (p<0.01). The cytoprotective potential of safranal was also accompanied by decreased ROS accumulation (p<0.001) and malondialdehyde level (p<0.001) following GA or QA insults. The data suggests that safranal exhibits oligoprotection potential by means of inhibiting oxidative stress parameters.",

The aim of the present study was to determine the effect of interferon beta (IFN \u00df) on the metabolome of MS patients to explore possible biomarkers of disease activity and therapeutic response. Twenty-one MS patients starting IFN \u00df therapy (Rebif\u00ae 44\u00a0\u03bcg; s.c. 3 times per week) were enrolled. Blood samples were obtained at baseline and after 6, 12, and 24\u00a0months of IFN \u00df treatment and were analyzed by high-resolution nuclear magnetic resonance spectroscopy. Changes in metabolites were analyzed. After IFN \u00df exposure,\u00a0patients\u00a0 were divided into responders and nonresponders according to the \"no evidence of disease activity\" (NEDA-3) definition (absence of relapses, disability progression, and magnetic resonance imaging activity), and samples obtained at baseline were analyzed to evaluate the presence of metabolic differences predictive of IFN \u00df response. The results of the investigation demonstrated differential distribution of baseline samples compared to those obtained during IFN \u00df exposure, particularly after 24\u00a0months of treatment (R2X\u2009=\u20090.812, R2Y\u2009=\u20090.797, Q2\u2009=\u20090.613, p\u2009=\u20090.003). In addition, differences in the baseline metabolome between responder and nonresponder patients with respect to lactate, acetone, 3-OH-butyrate, tryptophan, citrate, lysine, and glucose levels were found (R2X\u2009=\u20090.442, R2Y\u2009=\u20090.768, Q2\u2009=\u20090.532, p\u2009=\u20090.01).

However, it is still considered complex and challenging to understand and treat, in spite of the efforts made to explain its etiopathology. Despite the discovery of many genetic and environmental factors that might be related to its etiology, no clear answer was found about the causes of the illness and neither about the detailed mechanism of these environmental triggers that make individuals susceptible to MS.

Dimethyl fumarate (DMF) is an oral drug for multiple sclerosis with neuroprotective effects on oxidative stress. Using both in vivo and in vitro models, we investigated the effects of DMF on oxaliplatin-induced peripheral neuropathy and other side effects, as well as on the anti-tumor activity of oxaliplatin. Repeated intraperitoneal injection of 4\u2009mg/kg oxaliplatin (twice per week for 4 weeks) caused mechanical allodynia (as revealed by the von Frey tests), cold hyperalgesia (as revealed by the acetone tests), and axonal degeneration in the sciatic nerve of rats. Co-administration of oral DMF (200\u2009mg/kg, five times per week for 4 weeks) relieved oxaliplatin-induced mechanical allodynia but not cold hyperalgesia, and ameliorated axonal degeneration. In addition, DMF did not exacerbate oxaliplatin-induced body weight loss or bone marrow suppression, such as reduction in red blood cells, white blood cells, neutrophils and lymphocytes. Furthermore, DMF did not inhibit the anti-tumor activity of oxaliplatin in any cultured cancer cell line (C26, mouse colon carcinoma; HCT116, human colon carcinoma; MKN45, human gastric adenocarcinoma; MIA PaCa-2, human pancreatic carcinoma) or C26-bearing mice. These results suggest that DMF prevents oxaliplatin-induced mechanical allodynia and axonal degeneration without affecting the anti-tumor activity of oxaliplatin. Therefore, DMF may be useful for managing oxaliplatin-induced chronic peripheral neuropathy.",

The aim of this study was to investigate metabolic profiles, especially lipids in cerebrospinal fluid (CSF) using 1H-NMR spectroscopy and metabolomics analysis to discriminate MS patient group from the control ones. In this study, 19 MS patients and 19 controls, without neurological problems, patients were enrolled. To obtain the CSF metabolic profiles, NMR spectroscopy was used. Hydrophilic and hydrophobic compounds were analyzed using univariate and multivariate supervised analysis orthogonal partial least square discriminant analysis (OPLS-DA). Targeted OPLS-DA analysis of 32 hydrophilic and 17 hydrophobic compounds obtained 9 hydrophilic metabolites and 8 lipid functional groups which had the highest contribution to patient's group separation. Lower concentrations of CSF hydrophilic and hydrophobic compounds were observed in MS patients as compared to control group. Acetone, choline, urea, 1,3-dimethylurate, creatinine, isoleucine, myo-inositol, leucine, and 3-OH butyrate; saturated and monounsaturated acyl groups of \u03c9-9, \u03c9-7, \u03c9-6, \u03c9-3, and fatty acid, triglycerides, 1,3-DG, 1-MG, and unassigned component signal at 3.33\u00a0ppm were the most important signal compounds in group separation. Analysis of metabolic profile of raw CSF and their lipid extract shows decreased levels of many compounds and led to the conclusion that MS patients could have a disturbance in many metabolic pathways perhaps leading to the decreased level of acetyl-CoA and/or inflammation. CSF metabolic profile analyses could be used as a fingerprint for early MS diagnosis.",

        "31841592": "ID: 31841592\nTitle: Association Between Cigarette Smoking and Multiple Sclerosis: A Review.\nAbstract: Cigarette smoking is a common environmental exposure and addiction, which has severe health consequences. Smoking is a risk factor for multiple sclerosis (MS); also, smoking has been associated with disease activity and overall prognosis for patients with MS. Cigarette smoking is an irritative agent on the lungs, in which a proinflammatory cascade starts that culminates in autoimmunity. Inflammation may increase the risk of MS in some individuals, in a process driven by antigen cross-reactivity between lung antigens and myelin antigens. Genetics plays a central role in the individual predisposition to mounting an autoimmune reaction. Also, free radicals, cyanates, and carbon monoxide in cigarette smoke may be directly toxic to neurons. Patients with MS who smoke have higher rates of disease activity, faster rates of brain atrophy, and a greater disability burden. Some of the outcomes of smoking were found to be reversible, which makes counseling key. The pathways involved in cigarette smoking should be further analyzed to understand the mechanisms whereby smoking worsens MS prognosis. The proinflammatory and neurotoxic outcomes of cigarette smoking may be shared by other environmental exposures, such as pollution and organic solvents. From a global perspective, efforts should be made to diminish the prevalence of cigarette smoking in patients with MS.",

For 18 exposures not suitable for MR analysis, we conducted a systematic review to obtain the latest meta-analyses evidence on their associations with MS. Childhood and adulthood body mass index were positively associated with MS, whereas physical activity and serum 25-hydroxyvitamin D were inversely associated with MS. There was evidence of possible associations of type 2 diabetes, waist circumference, body fat percentage, age of puberty and high-density lipoprotein cholesterol. Data of systematic review showed that exposure to organic solvents, Epstein Barr virus and cytomegalovirus virus infection, and diphtheria and tetanus vaccination were associated with MS risk.

Several environmental factors have been discussed as possible causing agents, e.g. organic solvents, whose impact on the disease is analysed in this review. Systematic search strategies were used to identify high-quality studies of workers exposed to organic solvents, published up to September 30, 2019, in databases, such as PubMed, Cochrane library and Scopus. The exposure was in most studies obtained by questionnaires, supplemented with telephone interviews. The diagnosis MS was mainly detemined following a thorough neurological examination. Finally, fourteen case-control studies and two cohort studies met the inclusion criteria and were included in the meta-analysis. Random effects models were used to pool the results of the studies. The odds ratios from the 14 case-control studies included in the meta-analysis ranged from 0.12-4.0. Five case-control studies and one cohort study showed a significant association between the development of multiple sclerosis and exposure to organic solvents. The results from the other nine case-control studies and from one of the two cohort studies did not reach statistical significance. The pooled data from the 14 case-control studies gave an OR of 1.44 (95% CI 1.03-1.99), which shows a moderately increased risk of developing MS after exposure to organic solvents. The final interpretation of the result is that organic solvents may be slightly associated with an increased risk to develop MS. In addition, other factors, e.g. genetic markers and smoking, may contribute to the development of the disease.",

Seventeen primary caregivers of people with MS were interviewed using purposive sampling techniques. Data were analyzed using content analysis method. Two main categories of strategies were determined: (a) Strategies to alleviate intrapersonal challenges of occupational adaptation; and (b) Strategies to alleviate environmental challenges of occupational adaptation. These included various skills and solutions that aided primary caregivers' adaptation toward occupational challenges.

A State scheme includes a list of accepted associations between occupations and diseases with evidence of a causative association. Epidemiological evidence of a doubled risk in the occupation concerned is usually required. This takes no account of variation of exposures within occupations, excluding many occupations where risk is less than doubled. In such cases, compensation for a perceived industrial illness may be obtained in Civil Courts, where excessive exposures can be considered. To show that in the Civil Courts evidence of excessive exposure may lead to compensation for diseases which are not yet compensable as Industrial Injuries in the UK and to draw attention to the association of multiple sclerosis (MS) with solvent exposure. We report the case of an industrial spray painter, who claimed his MS had been caused by high-level exposure to organic solvents, and our examination of the epidemiological evidence submitted. The painter received compensation by an out-of-court settlement, despite the overall epidemiological risk in relation to solvent exposure having been shown to be less than doubled. The evidence hinged on individual risk in relation to high exposure, genetic susceptibility and demonstration of a plausible mechanism. High organic solvent exposure may lead to the development of MS.

Here, DNA genotyping was done for HSP70 gene polymorphisms, including HSP70-1 +190 G>C, HSP70-1 -110 A>C, HSP70-1 +438 A>C, and HSP70-hom +2437 A>G in two groups including Iranian MS patients and controls. A standard phenol/chloroform method isolated DNA samples from peripheral blood. Sequence-specific amplification (SSP) polymerase chain reaction (PCR) was used for genotyping polymorphisms. Overall, 76 (35.80%) MS patients and 136 (65.10%) controls were studied with an age mean of 36.0 \u00b1 8.0 years. Female/male was significantly higher in patients than in controls (4.43 vs. 0.10, P < 0.001). The average age was significantly lower in patients (P < 0.001). The most common clinical feature was relapsing-remitting (RR) MS; more than half of the population was Fars. Results showed that genotypes of HSP70-hom +2437 C>T had a significant relation with MS (OR = 2.0, 95% CI = 1.0-5.0, P = 0.03) and the same applies to HSP70-1 -110 A>C (OR = 0.0, 95% CI = 0.0-1.0, P < 0.001).

The purpose was to assess the relationships of ketone bodies with biomarkers of metabolic, inflammatory, and oxidative stress in MS. Methods: Blood samples and neurological assessments were obtained from 153 healthy controls (HC), 187 relapsing-remitting (RRMS), and 91 progressive MS (PMS) patients. AcAc, BHB, and acetone were measured using proton nuclear magnetic resonance spectroscopy. Indices of inflammatory vulnerability (IVX), metabolic malnutrition (MMX), and metabolic vulnerability (MVX) were computed from the NMR profiles. Cholesterol, apolipoprotein, lipid peroxidation, and antioxidant profiles were obtained. Regression analysis adjusted for age, sex, body mass index, and HC, RRMS, or PMS disease status. Results: AcAc and BHB levels were greater in MS compared to HC. BHB and ketone bodies were positively associated with disability on the MS Severity Scale and ambulation time. BHB was positively associated with IVX, MMX, and MVX. AcAc was positively associated with MMX and negatively associated with IVX and MVX. Total ketone body concentration was positively associated with MMX and MVX. BHB and AcAc levels were negatively associated with the amino acids alanine, valine, and leucine. Conclusions: Ketone bodies are associated with inflammatory vulnerability, metabolic vulnerability, and ambulatory disability measures in MS.",

Primary data on verified LOMS cases were received from Iran's national MS registry, with additional information gained via telephone interviews. The potential risk factors for LOMS were examined using a questionnaire modified from global case-control studies. Age and sex-matched healthy controls were selected using face-to-face interviews. The collected data were analyzed using matched logistic regression in Stata software version 14, reporting adjusted odds ratios (OR), and 95\u00a0% confidence intervals, with a significance level set at p\u00a0<\u00a00.05. This study examined 82 LOMS cases and 207 matched controls. The mean age of cases and controls was 61\u00a0years. The findings revealed that moderate and high sunlight exposure during adolescence were related with 0.33 (95\u00a0% CI: 0.18-0.58) and 0.15 (95\u00a0% CI: 0.04-0.46) times decreased risks of developing LOMS, respectively. Similarly, compared to those with low sunlight exposure, participants with high and moderate sunlight exposure during adulthood had a lower chance of developing MS disease (OR = 0.35, 95\u00a0% CI: 0.18-0.69) and (OR = 0.40 95\u00a0% CI: 0.18-0.85) receptively. Moreover, age at first menstruation (p\u00a0=\u00a00.45), age at first delivery (p\u00a0=\u00a00.49), abortion history (p\u00a0=\u00a00.79), and oral contraceptive consumption (p\u00a0=\u00a00.18) did not significantly differ among the groups (all p\u00a0>\u00a00.05). The odds of developing LOMS were 2.47 (95\u00a0% CI: 1.05-5.81) times higher for 10 to 90\u00a0min of heavy physical activity per week and 2.39 (95\u00a0% CI: 1.08-5.27) times higher for over 90\u00a0min. Various emotional stress, including death of a loved one (OR\u00a0=\u00a02.19, 95\u00a0% CI: 1.07-4.48), family disruption (OR\u00a0=\u00a02.93 95\u00a0% CI: 1.62-1.02), homelessness (OR\u00a0=\u00a09.1 95\u00a0% CI: 1.4-57.5), employment dismissal (OR\u00a0=\u00a04.0, 95\u00a0% CI: 1.31-12.1), and unemployment (OR\u00a0=\u00a03.1, 95\u00a0% CI: 1.25-7.62), were significantly associated with an increased risk of developing LOMS. Depression (OR\u00a0=\u00a05.5, 95\u00a0% CI: 2.7-10.9), measles (OR\u00a0=\u00a02.63, 95\u00a0% CI: 1.4-4.8), and a family history of MS (OR\u00a0=\u00a04.7, 95\u00a0% CI: 1.4-15.6) were also associated with higher risk of LOMS development. Sunlight exposure was shown to have a strong protective impact against LOMS. Furthermore, intensive physical activity, psychological stresses such as family upheavals, medical illnesses such as depression, and a positive family history of MS may all be associated with an increased risk of LOMS. These findings emphasized the importance of preventive measures for older individuals affected by the disease.",

It is unknown if these substances can affect the course of autoimmune diseases. This study was based on 907 individuals with multiple sclerosis (MS) and 907 matched controls, where the MS cases were followed longitudinally using the Swedish MS register. We demonstrate sex- and disease-specific differences in serum PFAS concentrations between individuals with MS and controls. Moreover, two OH-PCBs (4-OH-CB187 and 3-OH-CB153) are associated with an increased risk of developing multiple sclerosis, regardless of sex and immigration status. With a clinical follow-up time of up to 18 years, an increase in serum concentrations of perfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), and perfluorodecanoic acid (PFDA) decreases the risk of confirmed disability worsening in both sexes, as well as perfluoroheptanesulfonic acid (PFHpS) and perfluorononanoic acid (PFNA), only in males with MS. These results show previously unknown associations between OH-PCBs and the risk of developing MS, as well as the inverse associations between PFAS exposure and the risk of disability worsening in MS.",

This study aimed to evaluate the toxicological effects of PM2.5 associated with inflammatory factors in a mouse's multiple sclerosis (MS) model. Thirty C57BL/6 male mice were categorized into five groups: a group of healthy mice, a control cuprizone-induced MS group, and three MS-induced groups, intranasally exposed to three concentrations of ambient air PM2.5 (5, 10, and 20\u2009mg/mL) from Tehran in a phosphate-buffered saline (PBS) solution. All mice were investigated by motor function, molecular, and histopathological assays. Moreover, the chemical content of the collected PM2.5 was assessed and reported. The cumulative exposure doses were equal to 0.025, 0.05, and 0.1\u2009mg per gram of body weight of mice, which were approximately 3.52, 7.04, and 14.08 times higher than the human daily dose in Tehran. The PM2.5-exposed groups showed a high inflammatory response characterized by a significant increase in the mRNA expression of tumor necrosis alpha (TNF-\u03b1), NLRP3, and interleukin 18 (IL-18). In addition, the PM2.5-exposed groups exhibited a notably lower velocity level, total traveled distance (TD), and duration traveled in the central zone (DC) than the control group. The histopathological assays revealed significant pathological alterations and demyelination in the PM2.5-exposed groups compared to the control group. Identifying the risks and reducing the likelihood of exposure through preventive measures and regulations can result in financial savings and improve the quality of life for MS patients.",

The common view is that the pathological autoimmunity develops in genetically predisposed individuals upon exposure to an environmental trigger. This highlights the importance of recognizing and deconstructing the effects of environmental agents in rheumatic diseases. Several factors have been identified in the last decades, with detrimental or protective effects, impacting not only on disease onset, but also on its natural history. Cigarette smoking has been identified as one of the strongest environmental risk factors, being associated with disease development and severity for several rheumatic diseases, including rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and spondyloarthropathies. Moreover, other airborne pollutants, such as silica, solvents, asbestos and metals are recognized risk factors for rheumatic diseases. The effect of some other agents is however not straightforward, of which a remarkable example is alcohol consumption. Alcohol has been associated with both pro- and anti-inflammatory effects, exerting a variable effect on rheumatic diseases depending on quantity and frequency of consumption, as well as sex and ethnicity. Similarly, ultraviolet light exposure has been associated with a higher risk of SLE but lower risk of RA. The relationship between microbial exposure and autoimmunity is also complex: while some infectious agents increase the risk of rheumatic diseases, it is widely accepted that less exposure to microbial agents, particularly during immune system development, increases the risk of autoimmunity. Furthermore, in recent years the spotlight has switched to the human microbiome, as alterations in organ-specific microbiome composition are anticipated to be early participants in the onset of immune-mediated illnesses. The aim of this review is to highlight the most relevant environmental factors and their role in Rheumatology, with a specific focus on proposed pathophysiological effect and correlation with clinical outcomes.",

HAND is characterized by synapto-dendritic damage, yet the cause of this pathology is still under investigation. Various viral proteins, including the envelope protein gp120, have been proposed to be the leading neurotoxic agents underlying HIV-mediated neuronal degeneration. Gp120 has been shown to bind to neuronal microtubules (MTs) and impair their functions. The dynamic properties of MTs are modulated by microtubule-associated proteins (MAP), including MAP2, which is particularly abundant in dendrites. This review article explores how gp120 could be altering the function of the neuronal cytoskeleton by affecting MAP2. These effects may serve as a causal link between viral proteins and HAND pathology.",

To assess whether proximity to golf courses is associated with increased PD risk and to use information on groundwater vulnerability and municipal well locations to investigate drinking water contamination as a potential route of exposure. This case-control study included patients with incident PD and matched controls from the Rochester Epidemiology Project from 1991 to 2015. Data were analyzed between June and August 2024. Distance to golf courses, living in water service areas with a golf course, living in water service areas in vulnerable groundwater regions, living in water service areas with shallow municipal wells, and living in water service areas with a municipal well on a golf course. Risk of incident PD. All models adjusted for age, sex, race and ethnicity, year of index, median household income, and urban or rural category. A total of 419 incident PD cases were identified (median [IQR] age, 73 [65-80] years; 257 male [61.3%]) with 5113 matched controls (median [IQR] age, 72 [65-79] years; 3043 male [59.5%]; 4504 White [88.1%]). After adjusting for patient demographics and neighborhood characteristics, living within 1 mile of a golf course was associated with 126% increased odds of developing PD compared with individuals living more than 6 miles away from a golf course (adjusted odds ratio [aOR], 2.26; 95% CI, 1.09-4.70). Individuals living within water service areas with a golf course had nearly double the odds of PD compared with individuals in water service areas without golf courses (aOR, 1.96; 95% CI, 1.20-3.23) and 49% greater odds compared with individuals with private wells (aOR, 1.49; 95% CI, 1.05-2.13). Additionally, individuals living in water service areas with a golf course in vulnerable groundwater regions had 82% greater odds of developing PD compared with those in nonvulnerable groundwater regions (aOR, 1.82; 95% CI, 1.09-3.03). In this population-based case-control study, the greatest risk of PD was found within 1 to 3 miles of a golf course and risk generally decreased with distance. Associations with the largest effect sizes were in water service areas with a golf course and in vulnerable ground water regions.",

The presence of Lewy bodies and Lewy neurites, pathological hallmarks of PD primarily composed of aggregated \u03b1-Syn, further underscores its critical involvement. This correlation has led to the hypothesis that \u03b1-Syn aggregation actively contributes to PD development. Recent studies have implicated oligomers formed during the initial phases of protein aggregation as the primary neurotoxic agents driving cellular degeneration in PD. This pathological process worsens mitochondrial dysfunction, oxidative stress, and microglial activation, ultimately contributing to SNpc degeneration and PD progression. Currently, available PD medications only provide symptomatic relief and do not address underlying neuropathological mechanisms such as oxidative stress, mitochondrial impairment, \u03b1-syn aggregation, or SNpc degeneration. Moreover, long-term use of anti-PD drugs like L-DOPA can lead to motor complications and systemic side effects. As a result, repurposing traditional herbal medicines with antioxidant and anti-inflammatory properties presents a promising therapeutic approach. Studies suggest that berberine (BBR) may mitigate PD-related neuropathology. However, the exact mechanisms by which BBR exerts its neuroprotective effects remain unclear. This review explores the potential molecular pathways through which BBR could alleviate PD pathology.",

A small library of 10 compounds designed from the tritopic pharmacophore structure of ivermectin (IVM), a natural selective allosteric modulator of P2X4 receptor, was efficiently synthesized using a 1,3,5-tris(1,2,3-triazole)benzene scaffold. The efficacy of the compounds, termed MSKs, was screened using voltage patch clamp electrophysiology in microglia cells to assess the specific impact on P2X4 channel kinetics and properties. Since IVM modulates both ion conduction and channel gating of P2X4, MSK compounds were evaluated separately for both parameters following ATP applications. Most compounds induced an increase in the maximal inward current (Imax) indicating enhanced ion conductance. Notably, compounds MSK-7 to MSK-10, bearing two rigid 3-piperidine substituents and a highly hydrophobic menthyl group, also reduced receptor deactivation (\u03c4off). The therapeutic potential of two selected compounds, MSK-5 and MSK-9, each exhibiting distinct mechanisms of interaction with the P2X4 receptor, was evaluated in experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis. Compound MSK-5 induced a modest yet significant amelioration of neurological symptoms during the chronic phase of EAE. In contrast, compound MSK-9 delayed EAE onset and showed a higher amelioration of neurological symptoms. We concluded that rigid trivalent click scaffolds constitute a novel class of non-natural platforms enabling the rapid development of positive allosteric modulators of P2X4 receptors that target both ion conductance and receptor deactivation. These results provide a solid foundation for future advances in the discovery of therapeutic lead candidates for multiple sclerosis.",

Our study aimed to examine the performance of individuals with multiple sclerosis in speech understanding in noise and spectral resolution ability, which is known to be one of the functions of the central auditory system. A comparison was made between 32 individuals with multiple sclerosis (37.25 \u00b1 9.25 years) and 31 healthy individuals (34.96 \u00b1 8.42 years) in terms of the spectral resolution ability measured using the spectral-temporally modulated ripple test and speech comprehension performance in noise evaluated using the Turkish version of the matrix sentence test. There was no significant difference between the spectral resolution abilities of the two groups. However, speech comprehension performance in noise was significantly poorer in individuals with multiple sclerosis. Multiple sclerosis affects speech comprehension performance in noise, which is one of the central auditory system functions. In the auditory system evaluation of multiple sclerosis patients, performing peripheral and central auditory system evaluations together will yield more realistic results on communication problems that individuals may encounter daily.",

Its etiology may involve both genetic and environmental factors, including vitamin D levels, body mass index, infections, and smoking. This is the first comprehensive systematic review with meta-analysis that synthesizes and explore the role of many environmental risk factors in the etiology of MS. A systematic search of MEDLINE, SciVerse ScienceDirect and Web of Science were conducted for any original peer-reviewed article that included adult subjects diagnosed with and without MS that were exposed to any environmental risk factor. We did not set any time restrictions. Data were extracted and the quality assessment was performed with the Critical Appraisal Checklist for Case Control Studies. All the information was synthesized qualitatively and quantitatively (meta-analysis). We used the random-effects model based on the binomial distribution to calculate the pooled effects sizes (ES) regarding the risk of developing MS according to each potential risk factor. One-hundred thirty-two publications met all the eligibility criteria and were included in the review. Overall, 109,626 people with MS and 16,724,390 controls from 38 countries were included in the review. A total of 42 environmental risk factors were investigated as potential risk factors for MS. Among the various statistically significant associations, the pooled ES revealed a direct association between serological evidence of contact with EBV (ES\u2009=\u20091.96, 95% CI\u2009=\u20091.53-2.51), herpes virus type 6 (HHV-6) (ES\u2009=\u20092.84, 95% CI\u2009=\u20092.08-3.89) and varicella-zoster virus (ES\u2009=\u20091.33, 95% CI\u2009=\u20091.08-1.63) and the occurrence of MS.

The optimal eutectic combination of 1:2 malic acid and choline chloride (ChCl) was incorporated with Ba and water. The concentration of Ba used for preparing eutectogels was 2 w/w%. The results indicated that eutectic mixture of ChCl and malic acid greatly enhanced the solubility of DXM by more than 1700 times (0.19\u00a0\u00b1\u00a00.04 vs 324.20\u00a0\u00b1\u00a02.68\u00a0mg/mL). Increasing the water content to 60 w/w% in eutectogels resulted in decreased tensile strength (2.73 vs. 0.61\u00a0kg/cm2) and a narrower linear viscoelastic region in rheometry tests. All eutectogels retained their gel-like consistency at temperatures up to 80\u00a0\u00b0C. In texture profile analysis, eutectogels with lower water content showed more resistance to deformation than bassorin gel due to the physical cross-linking of the gelator. Cohesion tests demonstrated remarkable capacity of eutectogels to preserve structural integrity and superior adhesiveness than hydrogel counterparts. Eutectogels with 20\u00a0% water content had higher permeability of DXM through rat skin. Skin flux of DXM was significantly enhanced by eutectogel containing 20 w/w% of water (332.7\u00a0mg/cm2h) compared to the Ba gel with no eutectogel (just water and Ba) (57.1\u00a0mg/cm2h).

Pediatric MS (pedMS) offers a unique window to study environmental triggers, as\u00a0patients are close to the actual onset of the disease and have been exposed to fewer confounding\u00a0factors. PedMS is strongly associated to HLA-DRB1*15:01 and to non-MHC (Major Histocompatibility Complex) variants, with a higher burden compared to adults. HLA-A*02 allele seems to reduce MS risk. The role of rare variants is still under investigation. Several environmental causative factors have been identified: obesity, passive smoke, sun exposure, vitamin D, and others but the\u00a0strongest candidate is the Epstein-Barr virus, considered a prerequisite for MS development. In this paper we provide a summary of the results obtained so far in pediatric age.

The radiosynthesis was standardised in the FX2N synthesis module, and the precursor concentration was varied from 0.5 to 2.0\u00a0mg for labelling with 18F at 110\u00a0\u00b0C, with a reaction time of 5-10\u00a0min, followed by hydrolysis with 0.6\u00a0M HCl for 5\u00a0min. The final purification was standardised with various C18 cartridges to get the maximum yield. All standard quality controls were performed, along with in vivo stability. Briefly, 350\u00a0\u00b1\u00a050 MBq of the [18F]NAV4694 was injected intravenously in patients, and PET-MR imaging was performed.

In this study, a mouse model of rotenone exposure was established to investigate the pathological changes and underlying mechanisms of rotenone-induced neurotoxicity. Behavioral tests, molecular biology techniques, gut microbiota analysis, and short-chain fatty acid (SCFA) content measurements were employed. The results demonstrated that rotenone exposure significantly reduced body weight, impaired motor coordination, and resulted in the loss of dopaminergic neurons (TH+) in the substantia nigra. It also activated microglia (Iba-1+) and astrocytes (GFAP+), and promoted the expression of pro-inflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1) as well as oxidative stress markers (iNOS, COX2). Furthermore, rotenone disrupted blood-brain barrier (BBB) integrity, evidenced by degradation of tight junction (TJ) proteins and Evans blue leakage, via activation of the MAPK-MMPs pathway (upregulation of p-P38 and p-JNK). Additionally, rotenone disturbed the intestinal microenvironment, manifesting as inflammatory cell infiltration, reduced SCFA levels, and gut microbiota dysbiosis. Intervention with Wuzi Yanzong Pill (WYP) reversed the aforementioned pathological alterations. This study reveals for the first time that rotenone induces Parkinson's disease (PD)-like pathology by disrupting the gut-brain axis through the MAPK-MMPs pathway. Meanwhile, WYP exerts multi-target therapeutic effects by modulating the central-peripheral interaction network, offering novel insights into the pathogenesis and intervention strategies of PD.",

Mouse brain, liver, and kidney tissues were used to systematically compare the two matrix deposition methods of sublimation and spray coating in the FluoMALDI pipeline. Half of each tissue section was left uncoated as control by covering it during matrix application. Six MALDI matrices including 9-aminoacridine, norharmane, \u03b1-cyano-4-hydroxycinnamic acid, 2,5-dihydroxyacetophenone, 2,5-dihydroxybenzoic acid, or sinapinic acid were applied in equal amounts. Autofluorescence enhancements were evaluated using three fluorescence channels in the green, red, and far-red range of the spectrum, revealing matrix- and tissue-dependent fluorescence enhancement profiles. Norharmane matrix resulted in the most consistent tissue autofluorescence enhancements across deposition methods, with the highest enhancements in the green channel when applied by spray coating, and in the red and far-red channels when applied by sublimation coating. Matrix crystal size did not significantly impact the observed fluorescence enhancement effects for all six tested matrices. The two ionization modes of MALDI-1 and MALDI-2 imaging were also compared on brain, liver, and kidney tissue sections to assess lipid detection efficiency and spatial distribution in the FluoMALDI imaging pipeline. While the spatial distributions of phosphatidylethanolamine (PE) and phosphatidylcholine (PC) species were consistent across MALDI ionization modes and matrix deposition methods, lipid detection efficiency varied depending on the matrix type, matrix crystal size, tissue type, and MALDI ionization mode. Sublimation, which produced fine crystals without solvents, generally resulted in higher phospholipid detection efficiency than spray coating for lipids including PE(36:2) and PC(36:2) in both MALDI-1 and MALDI-2 imaging. These findings highlight that the matrix choice and matrix deposition method applied significantly affect tissue autofluorescence enhancement, spatial resolution, and lipid detection efficiency in MALDI-1 and MALDI-2 imaging modes, offering valuable insights for selecting optimal matrix deposition for FluoMALDI imaging based on a given study's research goals.",

Glycol ethers consist in a widely used class of organic solvents leading to workers and consumers exposure via many applications. Ethylene glycol ethers are gradually being replaced by propylene glycol ethers thought to be less toxic. However, their neurotoxicity is not systematically assessed before placing them on the market. Therefore, this study investigated the potential neurotoxicity of propylene glycol butyl ether (PGBE) for which no official occupational limit has been established. To this aim, new approach methodologies have been used. Human induced pluripotent stem cells-derived BrainSpheres model was exposed to PGBE and to its assumed human main metabolite, 2-butoxypropanoic acid (2BPA). An integrative multiomic approach (transcriptomics, proteomics, metabolomics and lipidomics) was adopted to assess molecular alterations, derive benchmark concentrations and define potential mechanisms of action. PGBE was neurotoxic at occupationally relevant exposure concentrations. This was shown for the first time in human cells. Although PGBE was more cytotoxic than 2BPA, both compounds showed very similar neurotoxicity. PGBE and 2BPA strongly affected the cell cycle, induced oxidative stress and perturbed energy and lipid metabolism. They also targeted specific nervous system processes, such as axon guidance and synapse organization. Finally, 2BPA might trigger ferroptosis by increased iron uptake. Our in vitro results show an urgent need for public health authorities to carefully assess the risk glycol ethers pose to humans, to properly protect the workers as well as individuals in the general population unknowingly exposed from indoor air contaminations.",

This study aims to explore the potential relationship and underlying mechanisms between PFASs exposure and ADs risk. We utilized Mendelian randomization (MR) and generalized summary-data-based MR (GSMR) to investigate potential associations between exposure to two major PFASs (perfluorooctanoic acid [PFOA] and perfluorooctanesulfonic acid [PFOS]) and the risk of ten ADs, using genetic data exclusively from European-ancestry populations. For significant associations, we subsequently conducted network toxicology analysis, applied machine learning algorithms to systematically screen and prioritize key genes, and assessed immune infiltration analysis to elucidate mechanisms. We then validated these findings through molecular docking and molecular dynamics simulations. MR and GSMR analyses demonstrated a significant association between PFOS exposure and an increased risk of multiple sclerosis (MS). Among 107 intersecting candidate genes, four genes (CASP3, STAT3, ESR1, and GSK3B) were identified as key target genes through machine learning. Molecular docking and molecular dynamics simulations further confirmed stable binding interactions between PFOS and these proteins. Additionally, immune infiltration analysis suggested these genes may contribute to immune microenvironment dysregulation in MS. Pathway analysis indicated that PFOS potentially influences MS pathogenesis through PPAR signaling and efferocytosis. Our integrated analysis reveals evidence supporting an association between PFOS and MS and uncovers underlying molecular mechanisms. These findings establish a foundation for further investigation into the role of environmental pollutants in autoimmune disorders.",

Articles were searched in PubMed, SciVerse ScienceDirect, and Web of Science. We included all clinical studies assessing the occurrence of MS at any age in association with the exposure to any environmental risk factor during childhood or adolescence. The main outcome was the occurrence of MS. The quality assessment was performed with the critical appraisal checklist for case-control studies. Pooled unadjusted effect sizes (OR) were calculated and reported with a 95% CI from random-effects meta-analysis. The review included 87 studies conducted across 20 countries. The studies analyzed diverse environmental risk factors, including infections, vaccinations, tobacco exposure, body mass index, and other pediatric exposures. EBV infection showed a significant positive association with MS risk (ES\u2009=\u20092.38, 95% CI\u2009=\u20091.80-3.15). Breastfeeding showed limited protective associations, and various adverse social experiences like bullying and sexual abuse were linked to increased MS risk. Active smoking during childhood/adolescence and obesity during these periods were associated with higher MS risk, while normal body mass index was protective. Antibiotic and chemical exposures, as well as vitamin D deficiency, were linked to higher MS risk. The review highlighted substantial heterogeneity and identified publication bias in studies on infections and vaccinations. Environmental risk factors for MS are important during childhood and adolescence. The first 20\u2009years are a key window for prevention and should be seen as an opportunity.",

In the grey matter of the cortex, nearly all OPCs divide slowly, yet they do not differentiate solely into mature OLs, leaving the exact role of these OPCs in the grey matter enigmatic. Oligodendroglia were traced using the sex-determining region Y-related high mobility group-box 10 (Sox10) Cre-ERT2 reporter mice. We compared the effect of tamoxifen dissolved in different solvents on the fate of Sox10 cells. We also compared the effect of tamoxifen dosage on the fate of Sox10 cells. The differentiation of labeled red fluorescent protein (RFP) cells was analyzed using immunofluorescence staining. Two groups of RFP cells, type A Sox10 (Sox10-A) cells and type B Sox10 (Sox10-B) cells, were identified in the cortex, striatum, hippocampus, thalamus, and hypothalamus. Sox10-A cells differentiate into platelet-derived growth factor receptor-\u03b2+, CD13+ pericytes, and smooth muscle myosin heavy chain 11+ smooth muscle cells when the mice received ethanol or high-dose tamoxifen. Sox10-B cells transform into glutamatergic neurons when the mice received high-dose tamoxifen. Sox10-B cells include perineuronal OPCs and OLs. This investigation provides evidence that a substantial proportion of oligodendroglia in the grey matter serve as mural cell precursors and neuronal precursors. These two phenomena may contribute to our understanding of the fate of oligodendroglia.",

MS is a multifactorial disease influenced by both genetic and environmental factors. The EXPOSITION study (registered on www.clinicaltrials.gov, NCT06325358) aims to investigate the association between environmental exposures (external exposome) and biological markers of oxidative stress and inflammation (internal exposome) in people with MS. This cross-sectional study will involve 200 individuals with MS, assessed for lifestyle and occupational variables and biological markers, including circulating microRNAs, neurofilament light chains, pro- and anti-inflammatory cytokines, and gut/nasal microbiota composition. The study will use advanced statistical models, such as generalised linear models and multivariate analyses, to assess associations between external exposures and biological outcomes. By integrating both environmental and biological factors, this research aims to deepen our understanding of MS mechanisms, providing insights that could lead to targeted interventions, personalised therapies, and public health strategies to mitigate MS progression.",

The hypothesis of a two-stage development, combining initial alteration in utero followed by malignant transformation later in life, has been suggested. This study examined the association between cumulative lifetime occupational and para-occupational solvent exposure and TGCT risk. The French multicenter case-control study TESTIS included 454 cases and 670 controls. Participants provided information on their occupational history; participants' mothers (N\u2009=\u2009547) provided information on their own and the father's occupational history. Solvent exposure was assessed by using the Matg\u00e9n\u00e9 job-exposure matrices. The influence of the parental and subject's occupational exposures over the lifetime and at different periods (i.e. fetal life/infancy; childhood; adolescence; subject's exposure) on TGCT was examined. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated by using conditional logistic regression models. An OR for TGCT of 1.03 (95% CI 0.59-1.79) was found for the lifetime solvent exposure. When each period was examined individually, the results showed an increased TGCT risk in adult males who were occupationally exposed to trichloroethylene (OR\u2009=\u20093.09; 95% CI 1.25-7.65); fuels and petroleum-based solvents (OR\u2009=\u20091.91; 95% CI 1.21-3.02); diesel, kerosene, and fuel oil (OR\u2009=\u20092.26; 95% CI 1.16-4.41); and ketones and esters (OR\u2009=\u20091.66; 95% CI 1.02-2.71), and suggested a positive association with solvent exposure during adolescence (OR\u2009=\u20091.77; 95% CI 0.95-3.31). Overall, this study did not suggest a substantial role of cumulative lifetime solvent exposure and TGCT risk. The results showed an increased TGCT risk associated with solvent exposure during adulthood. Indirect exposure to certain solvents during adolescence might also promote TGCT development.",

While TMEM63A variants are associated with HLD19, the specific lipid alterations in affected brain regions remain to be fully characterized. This study aimed to investigate the spatial distribution of lipid changes in a Tmem63a mutant rat model of hypomyelination. A homozygous Tmem63a c.500G\u2009>\u2009A p.(G167E) knock-in rat model (Tmem63aG167E/G167E) was established. Brain sections from Tmem63aG167E/G167E and Tmem63aWT rats (n\u2009=\u20093/group) were analyzed using MALDI-MSI for lipid profiling across nine distinct brain regions. Myelin structure was characterized by transmission electron microscopy (TEM) and g-ratio quantification. Statistical analyses included Mann-Whitney U tests for g-ratio distributions and ROC analysis for feature screening. Out of 702 analyzed features, 124 were differentially expressed. Lipids constituted the most altered class (43 features), including 22 glycerophospholipid, 9 fatty acid, 5 sphingolipid, 5 sterol lipid, and 2 prenol lipid species. These alterations were predominantly observed in white matter-rich regions and gray-white matter junctions. TEM revealed thinner and less dense myelin sheaths in Tmem63aG167E/G167E rats, with a reduced proportion of optimal g-ratios. This study provides a comprehensive spatial lipidomic characterization in a Tmem63a mutant rat model, revealing significant lipid alterations associated with hypomyelination. These findings offer new insights into the pathology of hypomyelination and highlight specific lipid species for future investigation.",

Fall risk assessments rely on in-person visits and occur infrequently, but mobile technology can provide portable, cost-effective, and multifactorial screening. The purpose of this study was to develop and evaluate the usability of a multifactorial fall risk app (MSafe) for older adults with MS. Methods: MSafe consists of 37 self-report questions, 9 quantitative cognitive and mobility assessments, and a final fall risk report. One-on-one semi-structured interviews were conducted with 21 older adults (>55) with MS. Participants independently used MSafe, were asked about their likes and dislikes, and completed the System Usability Scale (SUS). Interviews were video-recorded, transcribed, and coded into themes. Results: Three themes emerged: (1) simplicity of use, (2) progress monitoring, and (3) guidance and support. Overall, participants found MSafe easy to use, valuable to track and monitor their fall risk, and either confirmed or increased awareness of their own abilities. SUS scores averaged 84.9 \u00b1 14.7. Conclusions: MSafe is a comprehensive fall risk app that demonstrated high usability by older adults with MS. Future steps include implementing MSafe in home settings to examine fall risk management.",

Although smoking is a well-established risk factor for RA, the role of occupational inhalants in RA development is less well recognized. This study aimed to systematically review and synthesize existing evidence on the association between occupational inhalants and the risk of developing RA. We conducted a systematic review and meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, searching MEDLINE, Embase, and Web of Science from database inception to November 20, 2024. Eligible studies were cross-sectional, were case-control and cohort designs, were population-based, reported original data on occupational inhalant exposures and RA, measured exposures, included a comparison group, and used reliable RA ascertainment methods. Studies relying solely on self-reported RA or focusing on treatment, prognosis, sick leave, or death were excluded. Two reviewers independently conducted literature screening, data extraction, and risk-of-bias assessment using the Newcastle-Ottawa Scale. Random-effects meta-analyses with relative risk were performed for cohort and case-control studies, and heterogeneity was assessed using the I2 statistic. In total, 31 studies met inclusion criteria, and 25 were included in meta-analyses across 10 types of occupational inhalants. Significant associations with RA risk were observed for exposure to silica, asbestos, solvents, pesticides, fertilizers, animal dust, and engine exhaust (relative risks ranging from 1.25 to 1.49).

Although rare, the co-occurrence of IBD and demyelinating disorders is well-documented and may reflect shared immune, genetic, and environmental risk factors. As the therapeutic landscape of IBD expands to include biologics and small molecules that target immune pathways also implicated in MS, concerns around neurological safety have grown. In particular, anti-tumor necrosis factor agents have been consistently linked to new-onset or worsening demyelinating events, while other treatments such as sphingosine-1-phosphate receptor modulators and natali-zumab are licensed for both IBD and MS, though real-world data in patients with coexisting disease remain limited. This review synthesizes current evidence regarding the neurological safety and efficacy of IBD therapies in the context of demyelinating disease. It proposes a practical framework for clinicians, addressing management strategies for patients with confirmed MS, those at increased risk, and individuals who develop neurological symptoms during treatment. In the absence of formal guidelines, multidisciplinary collaboration, early recognition of symptoms, and careful treatment selection are important to optimize both gastrointestinal and neurological outcomes.",

While the clinical features of this occupational polyradiculoneuropathy/polyradiculopathy have been described, its immunologic basis remained unclear. The archived sera of 20 previously reported OIPN cases were evaluated for putative autoantigens by phage immunoprecipitation sequencing (PhIP-Seq). Healthy and diseased controls and cases of other inflammatory neuropathies, including chronic inflammatory polyradiculoneuropathy (CIDP), Guillain-Barr\u00e9 Syndrome (GBS), and axonal/mixed axonal-demyelinating inflammatory polyradiculoneuropathies (IPN, not meeting CIDP/GBS criteria), were also evaluated using by ELISA and CBA. PhIP-Seq data identified synaptophysin and growth-associated protein 43 (GAP43) as dominant autoantigens. Confirmation by enzyme linked immunosorbent assay (ELISA) and cell-based assay (CBA) showed that 11 patients with OIPN sera were positive for both synaptophysin-IgG and GAP43-IgG, four were positive only for synaptophysin-IgG, and one was positive only for GAP43-IgG. Thirteen of 15 (87%) synaptophysin-IgG positive patients had neuropathic pain. Electrodiagnostic features in 12 of 15 (80%) patients with OIPN were of a demyelinating or mixed axonal and demyelinating polyradiculoneuropathy. 12 out of 223 (5%) IPN patients tested positive for synaptophysin-IgG. 67% had demyelinating/mixed axonal-demyelinating electrophysiology, and all except one patient experienced neuropathic pain. Seven synaptophysin-IgG positive cases of spontaneous IPN among nine (78%) who received immunotherapy or cancer-directed therapy showed improvement.

The aim of the present study was to identify the genes or signaling pathways involved in the neurotoxicity and hepatotoxicity of 1-bomopropane in two inbred strains of rats. F344 rats and WNA/NUM rats were exposed to 1-bromopropane or filtered air by inhalation for either a single 8-hour session, or 8 h daily for 4 weeks. Motor nerve conduction velocity and distal latency were measured in the tail. At the end of the experiment, the animals were decapitated, and the hippocampus, liver, and blood were collected. Exposure to 1-bromopropane for 4 weeks increased distal latency in the tail nerve significantly in F344 and marginally in WNA/NUM. It also increased total and direct bilirubin in both rat strains. Eight-hour exposure increased metallothionein 2A, metallothionein 1 and NAD(P)H quinone dehydrogenase 1 expression in the liver of both rat strains, whereas 4-week exposure upregulated glutathione S-transferase alpha 3 and CD36 molecule in the liver of both strains. KEGG analysis showed that 8-hr 1-bromopropane upregulated pathways of apoptosis, NOD-like receptor signaling and colorectal cancer, in both the hippocampus and liver, whereas 4-week exposure upregulated NOD-like receptor signaling pathway both in the hippocampus and liver of the two rat strains. Insulin signaling pathway was upregulated persistently in the hippocampus of the two rat strains.

This study examined associations between serum concentrations of 14 per- and polyfluorinated substances (PFAS) and three hydroxylated polychlorinated biphenyls (OH-PCBs) and the onset of multiple sclerosis (MS), utilizing data from the Swedish population-based Epidemiological Investigation of Multiple Sclerosis (EIMS) cohort, comprising 907 MS cases and 907 matched controls. We employed single-substance logistic regression and quantile g-computation to evaluate cumulative and individual compound associations. We considered linear and non-linear risk patterns while adjusting for lifestyle factors and MS-associated HLA alleles. Our analysis revealed non-linear associations for several individual compounds, particularly perfluorooctane sulfonic acid (PFOS), perfluorononanoic acid, 2,2',3,4',5,5',6-heptachloro-4-biphenylol (4-OH-CB187), and 2,2',4,4',5,5'-, Hexachloro-3-biphenylol (3-OH-CB153), with increased odds of MS. Interaction analyses further indicated that the association between PFOS and MS odds was modified by the presence of the HLA-B*44:02 allele, known for its protective effect on MS risk. Mixture modeling highlighted that combined exposures to PFAS and OH-PCBs significantly increased MS odds, even when associations for individual compounds were weak or absent. These findings emphasize the complexity of associations between environmental contaminants, lifestyle and genetic risk factors, and the odds of MS. They underscore the importance of addressing co-exposure in environmental health research and call for further studies to elucidate underlying biological mechanisms.",

The gut-brain axis has emerged as a critical bidirectional communication system, with growing evidence establishing gut dysbiosis as a causal factor in AD pathogenesis. This dysbiosis, characterized by a reduction in beneficial microbes and an increase in pro-inflammatory taxa, compromises intestinal and blood-brain barrier integrity, promoting systemic inflammation and the translocation of neurotoxic agents like lipopolysaccharide (LPS). Consequently, the balance of key microbial metabolites is disrupted, reducing neuroprotective short-chain fatty acids (SCFAs) and indoles while elevating inflammatory mediators, which collectively exacerbate neuroinflammation, amyloid-\u03b2 (A\u03b2) deposition, and tau pathology. This review evaluates promising interventions, including probiotics, anti-inflammatory diets, exercise, and phytochemicals that can restore microbial balance, enhance barrier function, and improve cognitive outcomes in preclinical and early clinical studies. However, clinical translation is hindered by an overreliance on animal models, short-term studies, and insufficient mechanistic insight. Future research must prioritize large-scale human trials, multi-omics integration to elucidate signaling pathways, and personalized approaches that account for host genetics and baseline microbiome composition to fully harness the therapeutic potential of the gut-brain axis for AD.",

Using MRI of the brain of the ferret, a model organism for studying cortical morphogenesis, we create in vitro physical gel models and in silico numerical simulations of normal brain gyrification. Using observations of genetically manipulated animal models, we identify cerebral cortical thickness and cortical expansion rate as the primary drivers of dysmorphogenesis and demonstrate that in silico models allow us to examine the causes of aberrations in morphology and developmental processes at various stages of cortical ontogenesis. Finally, we explain analogous cortical malformations in human brains, with comparisons with human phenotypes induced by the same genetic defects, providing a unified perspective on brain morphogenesis that is driven proximally by genetic causes and affected mechanically via variations in the geometry of the brain and differential growth of the cortex. The wrinkled and folded surface of the human brain is both iconic and familiar. These folds allow a large cortical surface area to fit inside the skull and are essential for healthy brain function. The folds form during development when the brain\u2019s outer layer \u2013 the cerebral cortex \u2013 grows faster than the tissue beneath it, causing the surface to buckle. When this process is disrupted, the brain can develop abnormal folding patterns known as malformations of cortical development. In humans, these conditions are associated with epilepsy, intellectual disability and developmental delay. Studying how such malformations arise is challenging because human brain folding occurs before birth. To address this, researchers use animal models. The ferret is particularly valuable because its brain develops folds similar to those in humans, and many genes linked to human cortical malformations produce comparable folding defects in ferrets. Choi et al. wanted to find out whether the wide range of brain folding abnormalities seen in ferrets and their homologs in humans could be explained by changes in just a few physical properties of the developing brain. Specifically, they tested whether mutations linked to human cortical malformations alter the thickness or growth rate of the cortex. This question is important because different genetic syndromes often result in surprisingly similar brain shapes. By combining brain imaging, computer simulations, and physical gel models of brains that fold when their surfaces absorb solvents and swell (similar to how fingertips swell and wrinkle when wetted for a while), Choi et al. showed that normal brain folding in ferrets can be explained by mechanical forces generated during cortical growth. Both physical experiments with gels and computer simulations of brains with varying cortical thickness or growth rates reproduced folding patterns seen in both healthy and genetically altered ferret brains and their human homologs. Local thinning of the cortex generated many small, tightly packed folds, resembling polymicrogyria, a condition linked to mutations such as those affecting the gene SCN3A, which encodes instructions to form a sodium channel. Reducing overall growth produced smaller, less folded brains similar to microcephaly, which is associated with genes such as ASPM. In contrast, weaker folding with shallow grooves \u2013 characteristic of lissencephaly \u2013 emerged when growth was reduced and cortical thickness increased, as seen with disruptions to genes such as TMEM161B. These results suggest that diverse human genetic disorders converge on common physical mechanisms that shape the brain. The work of c provides a unifying framework linking specific genes to brain shape through physical growth processes. The ferret provides a useful model organism with direct implications for human brain development and misfolding. In the future, it could help researchers interpret human brain scans and understand why different genetic disorders lead to similar malformations. However, before such insights can inform clinical practice, the models will need to incorporate additional biological detail and examine how altered folding affects brain function. More broadly, the paper also raises the question of how variations in brain folding patterns arise in non-human brains, which is the subject of a related study.",

Edaravone and Dexborneol Concentrated Injection Solution (EDB) has been approved to improve neurological symptoms, daily living activities, and functional impairments resulting from acute IS. Our previous studies showed that replacing the benzene ring of Edaravone (Eda) with pyridine enhances its free radical scavenging capacity. In this study, we further oxidized the methyl group of Eda to a carboxylic acid and used a structural hybridization strategy with (+)-borneol to synthesize a series of pyrazole carboxylic acid borneol esters. We evaluated the free radical scavenging ability of the synthesized compounds, identifying candidate compound B16, which outperforms Eda. The IC50 values of B16 against DPPH and ABTS free radicals were 7.98\u00a0\u03bcM and 5.50\u00a0\u03bcM, respectively. Cellular studies have shown that B16 maintains intracellular redox homeostasis and mitochondrial function, while also alleviating DNA damage in an oxygen - glucose deprivation/reperfusion (OGD/R)-induced SH-SY5Y cell model, demonstrating excellent neuroprotective effects. Further in vivo pharmacodynamic studies have demonstrated that B16 not only restores cerebral blood flow and significantly reduces infarct size in middle cerebral artery occlusion/reperfusion (MCAO/R) mice, but also improves sensory and motor functions, and promotes the recovery of neuronal cells and the blood-brain barrier (BBB) in the brain. Notably, B16 exhibits excellent BBB permeability and shows promising brain exposure levels within 5\u00a0min of administration. Preliminary biosafety studies indicated no obvious organ toxicity from B16. Collectively, the pyrazole carboxylic acid borneol ester compound B16 holds promise as a candidate for anti-IS treatment.",

The present analysis serves to test whether the time trends of systemic lupus erythematous (SLE) in England & Wales and the United States are characterized by a similar birth-cohort patterns as other autoimmune diseases associated with Epstein-Barr virus (EBV).MethodsIn an observational study using the Vital Statistics of England & Wales and the United States from 1951 to 2022, the mortality trends of SLE were compared to those of Hodgkin lymphoma (HL), multiple sclerosis (MS), Crohn's disease (CD), and ulcerative colitis (UC).ResultsMortality from SLE rose among generations born during the 19th century and decreased among generations born subsequently during the 20th century. This birth-cohort pattern of SLE was matched by almost identical patterns underlying the occurrence of MS and CD, whereas mortality from HL and UC were similarly characterized by a birth-cohort patterns with a rise and fall in mortality that were shifted by 10-20\u00a0years towards earlier generations when compared to SLE, MS, and CD.ConclusionThe similarities in the birth-cohort patterns of SLE and other EBV-associated diagnoses suggest that they all share a common risk factor, such as EBV infection. The trends of SLE may have been shaped by underlying trends in the acquisition of EBV infection during adolescence or early adulthood.",

The aim is to enhance our understanding of central nervous system (CNS) demyelinating diseases. Additionally, the establishment of this cohort will address the critical issue of the lack of comprehensive genetic data and biological samples for precision diagnosis and treatment research related to neuroimmunological diseases in China. 56 hospitals in various regions of China were selected to participate in this study. The patients diagnosed with CNS demyelinating diseases were recruited, including clinically isolated syndrome (CIS), multiple sclerosis (MS), neuromyelitis optica spectrum disease (NMOSD), myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) and autoimmune glial fibrillary acidic protein astrocytopathy (GFAP-A). At the time of patient enrolment, the clinical information is designated as baseline data. The collected baseline data include demographic information, disease history, clinical features of each demyelinating event, treatment records, standardised scales, questionnaire assessments and laboratory test results. Furthermore, biological samples, MRI and high-density electroencephalography (hd-EEG) data will be collected at baseline. All patients will be followed up at 3 months and 6 months and annually thereafter. As of December 2024, 3866 patients with CNS demyelinating diseases have been enrolled, including 84 CIS, 282 MOGAD, 1405 MS and 2095 NMOSD. Our findings indicate that CNS demyelinating diseases, particularly NMOSD, are more prevalent in women in China, with significant age differences observed among NMOSD patients compared with those with CIS, MS and MOGAD. In future, all patients in our cohort will be followed up at 3 months and 6 months and then annually. By the end of December 2024, the database has been locked and is now being processed and analysed, while our data continue to be updated and expanded for further analysis. Both prospective and retrospective observations will be included in this study. Subsequent publications will emerge from this multicentre cohort, encompassing genomics, clinical cohort studies, hd-EEG biomarkers, imaging-based radiomics and electrical stimulation therapies.

Compared to peripheral nerve tissue, spinal nerve tissue is more vulnerable and typically non-regenerable. However, no effective treatments are currently available. Stem cells are attractive therapeutic cells because of their extensive self-renewal and pluripotent differentiation abilities. Accordingly, numerous studies are focused on their restorative potential. In the present study, we investigated the effects and mechanisms of stem cell therapy on spinal nerves damaged by 2,5-HD (a proximate toxic metabolite of n-hexane). Our results showed that spinal axonopathy induced by 2,5-HD was alleviated by bone mesenchymal stem cell (BMSC) transplantation. Further, by examining the expression of molecules associated with axonal outgrowth, NGF signaling was found to be involved in the regeneration of spinal axons. Moreover, intervention experiments showed that PTEN was also an essential component of BMSC therapy. Conclusively, our data suggested that BMSC transplantation can alleviate spinal injury induced by 2,5-HD through AKT/mTOR/CREB by NGF-dependent and -independent pathways.",

While traditionally, a relapsing and progressive disease course has been distinguished, it has increasingly become evident that elements of progression are the dominant factor for accumulating MS-related neurologic disability across all clinical courses and can be detected throughout the full disease trajectory in patients with MS. Therefore, defining the dominant pathophysiologic processes driving progression has become indispensable. Pathologic hallmarks of progressive MS include a compartmentalized inflammation within the central nervous system as well as associated neurodegenerative processes, finally leading to neuroaxonal and synaptic loss. Growing understanding of the pathophysiology has led to the development of an increasing number of targeted immunomodulatory treatment approaches for progressive MS. With the development of novel clinical trial designs and the evolution of clinical and paraclinical measures allowing accurate and rapid assessment of progression, new opportunities for personalized treatment regimens are likely to emerge.",

Several studies found a correlation between maternal or paternal smoking and the development of Multiple sclerosis in offspring. Given inconclusive findings from recent studies, we aim to conduct a systematic review and meta-analysis of the relation between parental tobacco smoking and the risk of Multiple sclerosis in offspring. We systematically conducted comprehensive search screening including (PubMed, Scopus, Web of Science, Embase, and Cochrane Library) until July 2025. This study aimed to assess the relation between exposure to tobacco smoke during pregnancy (maternal and paternal smoking) and the risk of Multiple sclerosis in offspring. Pooled estimates were calculated using a random-effects model. The PROSPERO registration is CRD420251117243. This study included nine studies involving 1,405,641 participants, including 5,452 Multiple sclerosis patients. We did not find a correlation between maternal smoking during and before pregnancy and risk of Multiple sclerosis in offspring (OR = 1.13, 95% CI [0.9, 1.43], P-value= 0.30, I2= 53.7%), (OR = 1.11, 95% CI [0.83, 1.48], P-value= 0.48, I2 = 0%) respectively. We found a statistically significant association between paternal smoking and the risk of Multiple sclerosis in offspring (OR 1.62, 95% CI [1.24; 2.11], P-value= 0.00036, I2= 0%). These findings highlight a complex relationship between parental smoking and offspring risk of MS. We observed no clear association for maternal smoking, whereas paternal smoking was associated with an increased risk in offspring. However, neither result is definitive, and further well-designed prospective studies are required to confirm these associations and clarify underlying mechanisms.",

Network toxicology identified 252 shared targets between sleep-related environmental pollutants (SREPs: NO2, formaldehyde, benzene) and SD. PPI network and diagnostic model identified four hub genes (HSP90AA1, RELA, PTGS2, MMP9) with moderate-to-high predictive value (AUC: 0.708-0.979). Immune infiltration analysis showing elevated T cells and reduced astrocytes and neurons in patients with SD. Molecular simulations confirmed stable SREP-hub protein binding, with benzene exhibiting the highest affinity. Crucially, mixed SREPs exposure induced more severe toxicity than individual pollutants, demonstrating true synergistic disruption. In vivo, SREPs metabolites disrupted sleep architecture, impaired the blood-brain barrier (BBB), and induced neurobehavioral deficits. In vitro studies using brain endothelial cells (BMVECs) revealed that SREPs directly increase permeability, suppress tight junctions, and activate a pro-inflammatory cascade involving NF-\u03baB signaling, enhanced MMP9 activity, and prostaglandin E2 synthesis. Curcumin intervention effectively counteracted these effects, restoring BBB integrity, normalizing sleep patterns, and suppressing hub gene expression and neuroinflammation in vivo and in vitro by targeting the identified hub gene network. Our integrated computational-experimental strategy establishes a novel \"pollutant-BBB-neuroimmune-sleep\" axis, providing a mechanistic framework for assessing cumulative environmental risks and advancing targeted interventions.",

Environmental factors like air pollution have been hypothesized to contribute to MS risk. This study aimed to map MS prevalence across Isfahan Province and evaluate differences by sex and urban versus rural setting, as well as to assess any association between ambient air pollution and MS prevalence. Data from 11,456 provincially registered MS patients in 28 counties in Isfahan, Iran, were examined in this cross-sectional ecological study. Official population estimates were used to calculate the county-level MS point prevalence per 100,000 population in 2023, stratified by sex. Ratios of females to males were calculated. Annual average PM\u2082.\u2085 levels for each county were obtained from state sources for the same period. MS prevalence was compared between urban and rural counties, and correlation/regression analyses were used to test associations with pollutant levels. The prevalence of MS varied widely, ranging from 322.7 in Isfahan County to 15.4 per 100,000 in rural Jarghouyeh. Although there was no significant correlation between the sex disparity and overall prevalence, females were more affected in every county (F/M ratio: 2.0-9.0).

Its hepatotoxic potential has been well documented in laboratory animals and occupationally exposed workers, establishing DMAC as a recognized industrial hazard. However, evidence regarding its neurological effects remains scarce. We report a clinical case of accidental DMAC inhalation associated with diffuse cortical hyperintensity on brain magnetic resonance imaging, raising concern for direct neurotoxicity. To address this knowledge gap, we investigated the neurotoxic potential of DMAC in a controlled rat model experiment. Animals subjected to repeated intraperitoneal DMAC administration exhibited cortical and subcortical histopathological alterations consistent with neurotoxicity, accompanied by significant hepatic and renal injury. These findings provide the first experimental evidence that DMAC toxicity extends beyond hepatotoxicity to involve the central nervous system and kidneys, highlighting its potential for multi-organ toxicity and reinforcing concerns regarding occupational exposure risks.",

Lipid abnormalities in MS have recently attracted renewed research interest, with studies focusing both on dysregulation of lipid signaling pathways and on alterations in standard lipid profile components, including total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides (TG), and non-HDL cholesterol. Although disturbances in serum lipid profiles are consistently reported in patients with MS, their origin remains unresolved. Emerging data indicate that dyslipidemia may stem from aberrant cholesterol metabolism within the CNS, secondary to demyelination and myelin sheath destruction, leading to the release of lipid-rich debris and subsequent systemic metabolic imbalance. These lipid changes appear to correlate with blood-brain barrier (BBB) dysfunction, suggesting a link between peripheral lipid metabolism and CNS inflammation. This review summarizes current knowledge on the mechanisms underlying dyslipidemia in MS, its potential impact on disease progression, and its relevance as a possible therapeutic or biomarker target in future translational studies.",

We investigated which environmental factors are associated with a first clinical event in RIS patients. Subjects presenting as RIS (cases) or as clinically isolated syndrome (CIS)/relapsing-remitting multiple sclerosis (RRMS) at onset (controls) were included. Patients were administered an environmental questionnaire. The distribution of clinical and demographic characteristics and environmental factors was analysed. RIS subjects were divided according to time of conversion to MS and clinical and demographic characteristics and environmental factors were investigated as risk factors for conversion. Fifty-two RIS and 216 controls were included. Controls were younger at diagnosis (33.4 vs 39.0 years old), while RIS patients had more frequent onset with supratentorial symptoms (26.9% vs 8.3%). Spending more time outdoor during childhood was associated with a higher risk of a CIS/RRMS onset (odds ratio (OR) 0.24, 95% confidential interval (CI): 0.09-0.65, p\u2009=\u20090.0049).

While current therapies primarily focus on immunomodulation, emerging evidence underscores a critical bidirectional interplay between mitochondrial dysfunction and lipid dysregulation in driving MS progression. Understanding this metabolic-mitochondrial axis may reveal novel therapeutic opportunities beyond immune modulation. This scoping review systematically maps recent literature (2015-2025) to delineate the mechanistic connections between mitochondrial dysfunction and lipid dysregulation in MS, identify current knowledge gaps, and highlight translational opportunities for targeted intervention. A systematic search of PubMed, Embase, and Scopus was conducted in 2025 following PRISMA-ScR guidelines. Thirty-six eligible studies examining mitochondrial-lipid interactions in human MS and preclinical models were included and synthesised thematically. Evidence converges on a self-reinforcing pathological cycle in MS, where dysregulated lipid metabolism impairs mitochondrial integrity, amplifying reactive oxygen species generation, energy failure, and further lipid disruption. This cascade contributes to oligodendrocyte injury, demyelination, ferroptosis, and axonal degeneration. Importantly, therapeutic strategies that restore lipid-mitochondrial homeostasis, such as mitochondrial antioxidants, lipid modulators, and metabolically active immunotherapies, demonstrate promising neuroprotective effects in preclinical studies. The evidence supports a model in which the bidirectional feedback loop between mitochondrial dysfunction and lipid dysregulation represents a significant mechanism contributing to neurodegeneration in MS. Clinically, these insights highlight opportunities for earlier diagnosis and more personalised disease management through the integration of lipid-based biomarkers into patient monitoring and treatment selection. Targeting this metabolic axis holds significant promise for developing next-generation disease-modifying therapies to slow disease progression, enhance neuroprotection, and improve functional recovery across different MS subtypes.",

Predicting MS progression is challenging due to the disease's heterogeneity. This study aimed to apply Artificial Intelligence (AI) methods to investigate the association between the MS Severity Score (MSSS), which is a measure that integrates disability level and disease duration, and patients' longitudinal clinical data and environmental exposures. Methods We integrated long-term clinical records from the Mondino MS Center (Pavia, Italy) with environmental data, including air pollution and weather conditions, based on patients' residential locations. To address missing data, we applied a hybrid imputation strategy combining exponentially weighted moving average and linear mixed-effect models. Automated Machine Learning (AutoML) was used for feature selection. We evaluated multiple Deep Learning (DL) architectures, including recurrent neural network, long short-term memory, and Gated Recurrent Unit (GRU), using varying historical window lengths to predict the MSSS class at the next follow-up. Results The final retrospective dataset comprised 4022 visits from 535 MS patients. AutoML identified both clinical and environmental variables as important features for prediction. Models incorporating environmental data performed comparably to or better than those using only clinical variables. The GRU model achieved the most stable performance, with an average Area Under the Curve of 0.814 when environmental data were included with four prior visits. Moreover, SHAP-based feature importance ranked environmental variables like PM10, PM2.5, nitrogen dioxide, precipitation, and humidity among the top predictors. Conclusion Incorporating environmental exposures into DL models can improve MSSS prediction, highlighting the value of diverse real-world data for MS monitoring. Prediction performance across different historical window lengths was comparable, suggesting that using data from two prior follow-ups (approximately one year of monitoring) may be sufficient to provide clinically meaningful predictions of MS progression.",

We investigated the prognostic value of combined NfL and GFAP for McDonald 2024 MS diagnosis after CIS and associations with key genetic and environmental risk factors. CIS participants, within six months after symptom onset, were included in a prospective cohort. We measured baseline serum NfL and GFAP levels and calculated z-scores. We evaluated weighted genetic risk scores for MS susceptibility, HLA-DRB1*15:01 risk and measured Anti-Epstein Barr virus Nuclear Antigen-1 (anti-EBNA1) immunoglobulin G (IgG) antibodies. Associations with MS diagnosis were evaluated using Cox proportional hazards models and time-dependent receiver operating characteristic (ROC) analyses. During follow-up, 162/221 CIS participants were diagnosed with McDonald 2024 MS. Separately, high NfL and GFAP associated with earlier MS diagnoses (hazard ratio (HR) 1.36, 95% confidence interval (CI) 1.12-1.66, p\u2009=\u20090.002, HR 1.12, 95% CI 1.02-1.42, p\u2009=\u20090.01, respectively). In combined models, only NfL remained independently predictive (HR 1.30, 95% CI 1.02-1.60, p\u2009=\u20090.01). Time-dependent ROC analyses showed similar results for NfL alone and combined with GFAP. HLA-DRB1*15:01-risk, but not GFAP or anti-EBNA1 IgG, improved predictive value. Our study found that serum NfL outperformed GFAP in predicting early MS diagnoses after CIS.

It remains unclear whether risk factors for primary progressive MS (PPMS) are comparable to those for relapse-onset MS (RMS). This study aimed to explore the association between selected environmental factors and PPMS risk, and compare their effect sizes with RMS. We used a case-control design with participants from two datasets: the Primary-Progressive MS Study (2015-2021) and the Australian Multi-center Study of Environment and Immune Function (2003-2006). Questionnaires collected data on smoking, infectious and concussion history before MS onset, supplement intake before age 15, and breastfeeding history. Unconditional, conditional, and weighted multivariable logistic regression evaluated associations with PPMS and RMS onset risk. A significant positive association was observed between tobacco smoking prior to onset (\u226520 pack-years: odds ratio (OR)=1.75, 95% confidence interval (CI)=0.96-3.20, P for trend=0.03) and history of infectious mononucleosis before MS onset (OR=1.74, 95% CI=1.05-2.88) in PPMS. Having vitamin supplements before age 15 (OR=0.52, 95% CI=0.31-0.87) and being breastfed during infancy (>6 months vs. never: OR=0.52, 95% CI=0.27-0.98) were associated with reduced PPMS risk. For RMS, tobacco smoking prior to onset (ever smoker OR=1.62, 95% CI=1.15-2.30; \u226520 pack-years: OR=2.17, 95% CI=1.20-3.80, P for trend=0.007) and infectious mononucleosis (OR=1.76, 95% CI=1.19-2.61) were also significantly associated with increased risk, with no difference in effect sizes compared to PPMS. Other infections, supplement intake, and being breastfed were not associated with RMS risk. Marijuana smoking and concussion history were not associated with either PPMS or RMS. PPMS shares some common risk factors with RMS, such as tobacco smoking and infectious mononucleosis, with similar effect sizes. This suggests PPMS and RMS may share underlying disease mechanisms. Further studies are needed to validate the role of other factors associated with PPMS onset.",

A crucial role in the TRP molecule is played by indole, a bicyclic ring formed by benzene and pyrrole, which confers hydrophobic and antioxidant properties and the ability to act as a ligand for aryl hydrocarbon and pregnane X receptors. The first parts of the article examine sources, nutritional requirements, and three pathways of TRP catabolism. Physiologically, ~5% of dietary TRP is catabolized through the pathway forming serotonin and melatonin in the brain and enterochromaffin cells of the gut, ~85% through the pathway resulting in the formation of nicotinamide nucleotides and kynurenine and its derivatives in the liver and immune cells, and ~10% in gut microbiota to indole derivatives. Alterations of individual TRP catabolism pathways in aging, alcoholism, inflammatory bowel disease, metabolic syndrome, renal insufficiency, liver cirrhosis, cancer, and nervous diseases, e.g., depression, Alzheimer's and Parkinson's diseases, multiple sclerosis, and schizophrenia, are examined in the central section. The final sections are devoted to the benefits and adverse effects of TRP supplementation, the therapeutic use of various TRP metabolites, and the pharmacological targeting of enzymes, transporters, and receptors involved in TRP catabolism. It is concluded that all pathways of TRP catabolism are altered across a broad spectrum of human illnesses, and further investigation is needed to understand their role in disease pathogenesis better. The goal for clinical research is to explore options for TRP-targeted therapies and their integration into new therapeutic strategies.",

Inhibition of N-methyl-D-aspartate receptor (NMDAR) has been linked to the rewarding and behavioral effects of toluene. One of the avenues to enhance NMDAR function is to increase the levels of D-serine via inhibiting D-amino acids oxidase (DAAO) activity. The present study determined whether sodium benzoate, a DAAO inhibitor, could counteract the toluene-induced brain stimulation reward enhancement, behavioral disturbances, and hippocampal synaptic dysfunction after acute toluene exposure. Male mice received various doses of sodium benzoate before toluene exposure for assessment of intracranial self-stimulation (ICSS) thresholds, rotarod test, novel object recognition task, social interaction test, and long-term potentiation (LTP) and long-term depression (LTD) of hippocampal synaptic transmission. Sodium benzoate prevented the lowering of ICSS thresholds, motor incoordination, social withdrawal, object recognition memory deficit, and impaired LTP and LTD induced by toluene. These results indicate that sodium benzoate could ameliorate toluene-induced facilitation of brain reward function, behavioral disturbances, and synaptic plasticity impairment, suggesting that sodium benzoate may be a promising compound against acute toluene intoxication caused by unintentional or deliberate inhalation.",

Triggering receptor expressed on myeloid cells-2 (TREM2) promotes clearance of myelin debris, supporting remyelination in preclinical models. However, the relevance of TREM2 in people with MS is less understood. We evaluated TREM2 expression and function in autopsy CNS tissues from individuals with and without MS. Spatial transcriptomics and gene co-expression network analysis revealed TREM2 expression in chronic active MS lesioned white matter, where it was localised to glial cell rich clusters associated with lipid and cholesterol metabolism, cellular heat acclimation pathways, and regulation of oligodendrocyte precursor migration and differentiation. Immunofluorescence analysis confirmed that TREM2 was highly expressed in actively demyelinating MS white matter lesions (active lesion centres and chronic active lesion rims). In these areas, TREM2 was found in reactive microglia, perivascular macrophages, and infiltrating parenchymal macrophages. Similarities were observed between perilesional white matter (PLWM) and chronic active lesion rims, including presence of TREM2+ reactive microglia, which were rare in normal appearing white matter (NAWM). TREM2+ cells co-expressed microglia/macrophage markers Iba1, MHC class II, MS4A4A, CD68 and/or CD163, and PLIN2, a lipid storage marker. Almost all TREM2+ cells in active demyelinating white matter were also PLIN2+, while these cells were absent in NAWM. Abluminal TREM2+ PLIN2+ CD163+ vessel macrophages were particularly prominent in actively demyelinating MS white matter where they may play important roles in lipid metabolism and storage in the context of active demyelination. These findings highlight the involvement of TREM2 on both resident and infiltrating myeloid cell populations in response to the demyelinating insult within MS lesions that may directly or indirectly impact local oligodendrocyte myelination capacity and neuroprotection.",

While both processes occur in all individuals with MS, females more often present with heightened inflammatory activity, whereas males tend toward accelerated neurodegeneration and disability progression. This review synthesizes current evidence on biological, hormonal, genetic, epigenetic, and environmental mechanisms underlying sex-based differences in relapsing-remitting MS (RRMS), the most common MS subtype. We integrate findings from human studies, animal models, and molecular research to examine the contribution of genetics and epigenetic regulation including sex chromosomes, single nucleotide polymorphisms (SNPs), and microRNAs (miRNAs) to MS pathophysiology. We discuss the influence of sex hormones, including estrogen, progesterone, and testosterone, and environmental risk factors such as Epstein-Barr virus infection and vitamin D3 deficiency. Evidence suggests that X-linked immune-related genes, hormone - immune interactions, and sex-specific epigenetic regulation shape differential immune responses and neuronal vulnerability in males and females with MS. miRNAs emerge as critical molecular bridges linking genetic susceptibility, hormonal milieu, and environmental exposures to downstream inflammatory and neurodegenerative pathways. Understanding the mechanisms driving sex differences in MS may enable the development of targeted interventions addressing both neuroinflammation and neurodegeneration. Integrated miRNA - mRNA analyses, explicitly powered to assess sex as a biological variable, hold promise for identifying novel biomarkers and therapeutic targets. Such approaches could inform more personalized treatment strategies and improve long-term outcomes for all people with MS.",

Emerging evidence indicates a close association between lipid metabolism disorders and MS, wherein microglial neuroinflammation driven by aberrant lipid droplet accumulation represents a core pathological mechanism. In this study, we first performed GEO database-based differential gene enrichment analysis related to lipid metabolism and GWAS-based Mendelian randomization analysis, demonstrating that disordered lipid metabolism constitutes a key pathological feature of MS with lipid droplets playing a central role. Based on these findings and our previous work demonstrating the efficacy of APS in alleviating neuroinflammation and neurological deficits in experimental autoimmune encephalomyelitis (EAE) mice, we sought to elucidate its role and mechanism in regulating microglial lipid droplets metabolism and neuroinflammation in the EAE mice and LPS-stimulated BV2 microglia model. Results demonstrated impaired autophagic flux, increased lipid droplets accumulation, and elevated pro-inflammatory cytokine secretion in both EAE mice brain tissue and LPS-stimulated BV2 microglia model. Critically, APS intervention reversed these pathological changes. APS activated microglial autophagic flux, enhanced lipophagy function, cleared accumulated lipid droplets, and consequently suppressed pro-inflammatory factor secretion, thereby alleviating neuroinflammation. In conclusion, APS alleviates MS neuroinflammation partially by enhancing microglial lipophagy, which facilitates the elimination of lipid droplets accumulation. This finding provides a novel therapeutic strategy and lays a theoretical foundation for developing neuroprotective drugs targeting lipophagy.",
        "41764304": "ID: 41764304\nTitle: MALDI-TOF mass spectrometry imaging of sulfatide lipid expression in the CNS of mice with experimental autoimmune encephalomyelitis.\nAbstract: Changes in the composition and distribution of the lipids comprising the myelin sheath surrounding neuronal axons have been under-explored in neuroinflammatory diseases such as multiple sclerosis due to the complexities in the analysis of lipids in biological tissues. The application of mass spectrometry-based molecular imaging enables the study of the molecular components of demyelinating tissue. This provides a much better understanding of the complex molecular processes involved in lipid metabolism and the underlying neuroinflammatory demyelinating processes. Uncovering alterations in the lipid profiles during the demyelination processes can potentially elucidate new molecular targets for novel MS drug therapies. We have utilized mass spectrometry imaging (MSI) of in-situ sulfatide lipids in mouse CNS tissue to reveal their spatial distribution and relative abundance. We show that they are generally confined to the white matter region of the cerebellum. We provide a molecular snapshot of lipid alterations at different disease stages of experimental autoimmune encephalomyelitis (EAE), the animal model for MS. Our results suggest that alterations in sulfatide expression are greatest prior to the onset of clinical disease symptoms and are systemic through the white matter and not restricted to the focal inflammatory lesions pathognomonic of EAE and human MS. The lipid mass maps generated by MSI provide novel insights into the dynamics of lipid alterations during neuroinflammation.",

To investigate the link between air pollutant exposure and pediatric MS (pedMS) in an Italian cohort. PEDIGREE (Pediatric Italian Genetic and Environment Exposure) is a multicenter case-control study investigating genetic and environmental factors in MS before the age of 18. Information on environmental and perinatal exposures was collected through the PEQ-IT questionnaire. Air pollution data during the first, second, and third years prior to MS onset (PM2.5, PM10, O3, NO2, SO2, and CO levels) were obtained from the European Monitoring and Evaluation Program database. Data were available for 113 pedMS cases and 117 controls. We found statistically significant associations between pedMS and higher exposure to ozone (O3) in the first (OR\u2009=\u20091.11; 95% CI 1.03-1.19; p\u2009=\u20090.007), second (OR\u2009=\u20091.10; 95% CI 1.02-1.18; p\u2009=\u20090.012), and third (OR\u2009=\u20091.09; 95% CI 1.01-1.17; p\u2009=\u20090.025) year before MS onset, even after adjusting for gender, age at onset, sun exposure, parental smoking habit, and socioeconomic background. A one-unit increase in O3 exposure was associated with a roughly 10% increase in pedMS risk. O3 may play a significant role in the development of MS by promoting inflammation and oxidative stress.",
        "41780625": "ID: 41780625\nTitle: Mechanisms of environmental risk factors for autoimmune diseases.\nAbstract: Over the past few decades, autoimmune diseases have seen a steady upsurge in global prevalence and associated costs. While the exact reasons for these increases are unknown, this trend has been attributed to increased exposure to environmental agents that are also risk factors for autoimmune disease, including xenobiotic chemicals, infections, lifestyle changes, stressful life events, and altered microbiomes, with subsequent biochemical modifications that influence immune tolerance. This review explores current understanding of mechanisms relating to environmental agents contributing to autoimmune diseases. Here we focus on the key initial mechanistic pathways that include environmentally-induced DNA damage, epigenetic alterations, protein post-translational modifications - such as hapten formation, altered autoantigen structure and cellular locations - tissue barrier disruptions, molecular mimicry, and neuroendocrine dysregulation. The processes by which these initial effects result in secondary changes to influence immunological mechanisms, which can then contribute to the development of autoimmunity and autoimmune disorders, are also discussed. While understanding of the mechanisms of environmental triggers in autoimmune diseases has expanded in recent years, and they are considered fundamental architects of autoimmune phenotypes that imprint specific molecular signatures with prognostic and therapeutic value, many important issues remain unaddressed. These include conducting longitudinal exposome studies, defining the necessary and sufficient gene-environment interactions, understanding the synergistic effects of exposure mixtures, of exposure timing and susceptibility, and impacts of chronic psychosocial stress on immune function. Addressing these knowledge gaps and advancing our understanding of the underlying causal pathways are vital for developing preventive strategies and creating safer and more effective therapies for autoimmune conditions.",

Familial aggregation in MS is partially explained by susceptibility determinants, yet impact on early disease course after clinically isolated syndrome (CIS) is uncertain. We investigated associations of reported familial MS with genetic and environmental risk factors, and with clinical presentation and disease course after CIS. CIS participants were included in a prospective cohort within six months after symptom onset. Family history was assessed at baseline. We evaluated weighted genetic risk scores (wGRS) for MS susceptibility, 25-hydroxyvitamin D (25(OH)D) and body mass index (BMI), and determined HLA-DRB1*15:01 and MS severity SNP rs10191329 carriership. Anti-Epstein Barr virus Nuclear Antigen-1 (anti-EBNA1) IgG antibodies and 25(OH)D levels were measured. Disease course associations were estimated with Cox regression. Family members with MS were reported by 81/415 (19.5%) CIS participants. Familial MS was associated with higher MS susceptibility wGRS (7.54 (SD1.17) vs. 7.19 (SD1.22), p=0.04) and more frequent HLA-DRB1*15:01 carriership (first-degree 66.7%, other-degree 30.2%, no 38.4%, p=0.02). Anti-EBNA1 IgG and 25(OH)D levels did not differ, yet wGRS for lower 25(OH)D and higher adult BMI characterised MS participants with first-degree MS relatives. Baseline characteristics and disease severity measures were similar between participants with and without familial MS. Our results confirm that familial MS is associated with enrichment of genetic risk for MS susceptibility, low 25(OH)D and high BMI, but not with early disease course after CIS. These data support that MS susceptibility and disease course are driven by different pathophysiological processes.",

The etiology of this disease is not fully defined. Multiple genetic, epigenetic, environmental, and immunological factors have been associated with the development and perpetuation of this autoimmune and inflammatory phenomenon. Human endogenous retroviruses (HERVs), retroelements that comprise approximately 8% of the human genome, have been proposed as potential contributors to the loss of immune tolerance and may contribute to the development of RA. Exposure to certain environmental risk factors, cellular activation processes, and inflammation promotes HERV gene expression. Compared with healthy individuals, RA patients exhibit increased transcripts of particular HERVs in blood and synovium, mainly of the HERV-K family. In addition, autoantibodies targeting distinct HERV epitopes have been identified in patients with RA. A better understanding of the role of HERVs in RA, including their epigenetic dysregulation and their activation of the immune system, could be a relevant basis for developing new tools for the detection, diagnosis, and follow-up of patients, as well as for identifying alternative therapeutic targets in those individuals who are refractory to conventional treatments. This review examines the general features of HERVs and their potential role in the immune dysregulation of patients with RA.",
        "41812343": "ID: 41812343\nTitle: Integrated determinants of multiple sclerosis susceptibility: Genetics, environment, infection and the microbiota.\nAbstract: Multiple sclerosis (MS) arises from the convergence of polygenic immune susceptibility, environmental exposures, and infectious determinants, none of which alone is sufficient for disease expression. More than 200 genetic variants contribute to MS risk, with the HLA-DRB115:01 haplotype providing the strongest effect within a broader network of immune-regulatory loci. Functional genomic evidence shows that these variants primarily influence antigen presentation and lymphocyte activation, creating an immune landscape that can be further shaped by external factors. This review integrates epidemiological, genomic, and mechanistic data to outline the main determinants of MS susceptibility. Epstein-Barr virus infection emerges as the dominant infectious driver, with seroconversion preceding early neuroaxonal injury and clinical onset. In contrast, cytomegalovirus infection appears protective, likely through immune imprinting that counterbalances EBV-driven B-cell and T-cell activation. Environmental factors including cigarette smoking, adolescent obesity, vitamin D deficiency, circadian disruption, and gut microbiota dysbiosis further modify susceptibility by promoting proinflammatory immune programs and reducing regulatory stability. Many of these exposures interact synergistically with HLA-DRB115:01, amplifying risk beyond additive expectations. These determinants influence shared immunological pathways regulating antigen presentation, lymphocyte differentiation, and immune tolerance. Clarifying these biological interfaces highlights actionable domains including smoking avoidance, metabolic health optimization, vitamin D sufficiency, viral prevention strategies, circadian alignment, and microbiome-targeted interventions that may inform risk-reduction and early identification efforts.",

This study investigated this relationship using data from the internationally pooled SYNERGY study. Data from 14 case-control studies conducted in 13 European countries and Canada were pooled, including 28\u2009048 participants (12\u2009329 cases and 15\u2009719 controls). Lifetime occupational exposure to chlorinated solvents was assessed using the ALOHA+job-exposure matrix. ORs and 95% CIs were estimated using unconditional logistic regression, adjusted for study centre, age, sex, smoking (pack-years and cessation), cumulative exposure to five occupational lung carcinogens (asbestos, hexavalent chromium, polycyclic aromatic hydrocarbons, respirable crystalline silica and diesel engine exhaust), cumulative benzene exposure and employment in high-risk occupations ('List A' jobs). Associations were estimated across categories of exposure levels, durations and analyses stratified by smoking status and lung cancer subtypes. We found no evidence of an association between ever exposure to chlorinated solvents and lung cancer risk (OR 1.03; 95%\u2009CI 0.96 to 1.10). Among exposed individuals, a positive trend with cumulative exposure was observed (p=0.031), but not when non-exposed individuals were included (p=0.173). Positive trends were found with exposure duration (p=0.005 for exposed; p=0.048 overall); risks were modestly elevated (OR 1.11) in those exposed for 20 or more years. No increased risk was observed across smoking strata or lung cancer subtypes. This pooled analysis provides limited evidence of an association between occupational exposure to chlorinated solvents and lung cancer, though exposure-response trends were noted among exposed individuals.",

The aim of this study was to investigate the association between occupational exposure to industrial dust and MS and to assess potential interactions with smoking and HLA-DRB1*15:01. We conducted a Swedish population-based case-control study. Patients with incident MS age 16-70 years were consecutively identified by neurologists at 40 clinics (2005-2015). Eligibility criteria for participants were age 16-70 years, residence in Sweden, and a neurologist-confirmed diagnosis of MS according to the McDonald criteria. Controls without MS were randomly sampled from the national population register using density sampling and frequency-matched to cases on age, sex, and residential area. Occupational dust exposure was assessed using questionnaire data. Logistic regression was used to estimate odds ratios (ORs) and 95% CIs. Additive interactions between dust exposure and smoking and between dust exposure and HLA-DRB1*15:01 were assessed by calculating the attributable proportion (AP) due to interaction. An AP >0 is considered evidence of interaction. The analytic sample included 2,070 participants and 2,899 controls. The mean age at index was 34.4 years for participants and 35.4 years for controls. Women comprised 72.5% of participants and 75.1% of controls. Industrial dust exposure was associated with increased rate of MS (OR 1.30, 95% CI 1.05-1.63), with a dose-response relationship with duration (OR per 1-year exposure 1.03, 95% CI 1.00-1.06). Evidence of additive interactions was observed between dust exposure and smoking (AP 0.32, 95% CI 0.03-0.62) and between dust exposure and HLA-DRB1*15:01 (AP 0.25, 95% CI 0.002-0.52). Participants who smoked, were exposed to dust, and carried the HLA-DRB1*15:01 allele had an 11-fold increased rate of MS (OR 11.1, 95% CI 5.7-21.9), compared with those without any of these risk factors. Occupational dust exposure was associated with increased rate of MS, particularly in combination with smoking and HLA-DRB1*15:01, suggesting joint effects of occupational, environmental, and genetic risk factors. The reliance on self-reported occupational histories and potential residual confounding are important limitations. Further studies are warranted to clarify underlying mechanisms and to inform preventive strategies.",

Growing evidence indicates that nutrition, environment, and lifestyle significantly influence disease development, progression, and treatment response. Nutrients such as vitamins, minerals, omega-3 fatty acids, and polyphenols affect neuroinflammation, oxidative stress, mitochondrial health, and neurotransmitter function. Dietary patterns like the Mediterranean and ketogenic diets offer protective benefits in clinical and experimental contexts. Meanwhile, environmental neurotoxicants-air pollution, heavy metals, pesticides, and endocrine disruptors contribute to neurodegeneration via oxidative damage, synaptic impairment, and epigenetic alterations. Lifestyle factors, such as physical activity, sleep, stress, and substance use, affect brain plasticity, neurogenesis, and metabolic health, thereby influencing disease progression over time. These factors often share common pathways such as oxidative stress, inflammation, vascular injury, mitochondrial dysfunction, and protein misfolding, underscoring the need for a comprehensive prevention and treatment strategy. Emerging therapies now incorporate personalized nutrition, lifestyle changes, and environmental risk mitigation alongside traditional drugs, supported by advances in multi-omics, digital health, and systems biology. Public health efforts to reduce neurotoxic exposure and encourage healthy habits further strengthen these approaches. This review summarizes existing mechanistic and clinical knowledge, with a focus on the potential of nutritional, environmental, and lifestyle interventions in neurological diseases. It also outlines the future research required to enhance precision neurology and strategies for brain health prevention.",

EBV primarily infects memory B cells, transitioning between lytic (active) and latent (dormant) phases of infection. Our group has previously proposed two molecular mechanisms linking EBV pathogenesis to autoimmunity: one indicates that EBV lytic switching contributes to systemic lupus erythematosus (SLE) pathogenesis, while another posits that latency III is more crucial in the development of multiple sclerosis (MS). In this study, we tested the proposed molecular model using a cohort of EBV-transformed lymphoblastoid cell lines derived from individuals with either SLE, MS or healthy controls. Measuring the expression levels of a panel of EBV genes, representing the different phases of the EBV lifecycle, we found compelling proof-of-concept evidence validating our proposed model. This discovery highlights promising signatures for further investigation, where the same approach can be explored across other EBV-associated immune conditions, deepening our understanding of the virus's lifecycle dysregulation in autoimmunity etiology and ultimately aiding in the design of new treatments.",

This long-term extension (LTE) study was designed to assess the safety and efficacy of ponesimod 20\u00a0mg (P20 mg) during extended treatment. Participants who completed core OPTIMUM study entered OPTIMUM-LTE; Participants receiving P20 mg once daily (OD) in core continued with the same dose (P20\u00a0mg/P20\u00a0mg) and those receiving teriflunomide 14\u00a0mg OD switched to P20\u00a0mg (T14\u00a0mg/P20\u00a0mg) in the LTE study. Safety assessments included treatment-emergent adverse events (TEAE). Efficacy was assessed using annualized relapse rate (ARR), time to first confirmed relapse up to end of study (EOS), confirmed disability accumulation (CDA), and magnetic resonance imaging (MRI)-based endpoints. Of 1133 participants from core study, 877 were enrolled in 240-week LTE study (ponesimod: 439; teriflunomide:438). During LTE, 93.6% of participants in both groups experienced\u2009\u2265\u20091 TEAE; overall, serious TEAEs were experienced by 12.9% of participants (P20\u00a0mg/P20\u00a0mg: 12.8%; T14\u00a0mg/P20\u00a0mg: 13.0%) and TEAEs leading to study treatment discontinuation were experienced by 8.6% of participants (P20\u00a0mg/P20\u00a0mg: 7.7%; T14\u00a0mg/P20\u00a0mg: 9.4).

To our knowledge, n-hexane-toxic neuropathy presenting with a cauda equina-like syndrome has not previously been reported. CASE PRESENTATION: A 55-year-old man developed sensory and motor polyneuropathy over a 3-month period, with nerve conduction studies indicating demyelination. Initial treatment for suspected chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) with steroids and plasma exchange was ineffective, leading to worsening symptoms. The patient and his colleagues were found to have been habitually exposed to n-hexane in their printing work, and a sural nerve biopsy revealed the pathological findings typical of n-hexane-toxic neuropathy. Notably, cauda equina inflammation was observed on MRI and in the cerebrospinal fluid. Following intravenous immunoglobulin therapy, both neurological symptoms and findings from nerve conduction studies, MRI, and cerebrospinal fluid analysis gradually improved, eventually leading the absence of impairment in activities of daily living. CONCLUSION: In cases of polyneuropathy accompanied by inflammation of the cauda equina, and if exposure to n-hexane cannot be ruled out, sural nerve biopsy could be considered to assess for n-hexane-toxic neuropathy.",

Environmental risk factors, such as vitamin D deficiency and obesity, have also been implicated in multiple sclerosis pathogenesis. Statistical approaches building on these genetic data, such as Mendelian randomization and co-localization, have established putative causal links between environmental risk factors and multiple sclerosis risk, most notably for vitamin D and body mass index. However, studies have thus far revealed limited statistically significant interactions between host genetics and environmental factors beyond the major histocompatibility complex. Epigenetics (the study of non-nucleotide alterations to DNA, such as DNA methylation or histone acetylation) might provide a mechanistic framework for understanding how environmental and genetic factors interact in multiple sclerosis. Environmental factors, such as Epstein-Barr virus infection, vitamin D deficiency and smoking, are associated with epigenetic modifications at key multiple sclerosis-related genomic loci, altering the expression of multiple sclerosis risk genes in a cell type-specific manner. Transcriptomics have identified significant pathways via which genetic risk is realized, potentially providing targets for intervention. This review synthesizes current evidence on gene-environment interactions in the context of multiple sclerosis genome-wide association study findings, evaluates the strengths and limitations of various study methodologies, and discusses the challenges in elucidating the interplay between genetics and environmental factors. We propose potential strategies for future research to advance our understanding of the biological mechanisms underlying multiple sclerosis susceptibility in at-risk individuals.",

We compared treatment switching and time-to-switch within 1- and 2-year follow-ups between CladT-treated and fingolimod-, dimethyl fumarate-, or teriflunomide-treated patients with MS. Data for this retrospective observational study were sourced from the Komodo Healthcare Map\u2122 database and included patients aged \u226518 years in the US with \u22652 MS diagnoses \u226530 days apart; \u22651 claim for CladT, fingolimod, dimethyl fumarate, or teriflunomide between 1 April 2019, and 31 December 2020 (initiation date = index); no index DMT in the year prior to the index date (baseline); and continuous enrollment in healthcare insurance from baseline to 2 years after the index date (follow-up). Propensity score weighting with covariate adjusted logistic regression, Kaplan-Meier and Cox regression were employed to assess switching outcomes between groups. Eligible patients (n = 4709) treated with CladT (n = 269), dimethyl fumarate (n = 2314), fingolimod (n = 677), and teriflunomide (n = 1449) were identified from the database. CladT-treated patients were less likely to switch treatment during the 2-year follow-up (10%) compared to fingolimod- (27%), dimethyl fumarate- (44%), or teriflunomide-treated (34%) patients in the weighted cohorts. The adjusted odds ratios (95% confidence interval [CI]) for treatment switching at 2 years were 3.25 (2.03-5.32), 6.75 (4.29-10.92), and 4.65 (2.92-7.59) for fingolimod, dimethyl fumarate, and teriflunomide, respectively, relative to CladT. Cox regression results suggested significant differences in time-to-switch compared to CladT, with hazard ratios of 2.99 (95% CI: 1.89-4.71) for fingolimod, 5.45 (95% CI: 3.73-7.97) for dimethyl fumarate, and 4.06 (95% CI: 2.73-6.06) for teriflunomide. This real-world study revealed significantly lower treatment switching rates in CladT-treated patients than in fingolimod-, dimethyl fumarate- and teriflunomide-treated patients with MS.",

Over the past three decades, the MS therapeutic landscape has expanded considerably; however, treatment selection and switching remain guided primarily by clinical phenotype and imaging findings rather than molecular predictors of response. Despite extensive clinical trial evidence, prospectively identifying responders and non-responders to specific DMTs remains challenging. Genetic variability appears to influence differences in treatment efficacy, tolerability, and long-term outcomes in people with MS. Numerous candidate pharmacogenomic variants have been reported across interferon-\u03b2, glatiramer acetate, oral agents, and monoclonal antibodies; nevertheless, replication has been inconsistent, effect sizes are modest, and no genetic marker has yet been clinically validated for routine use. Consequently, pharmacogenomics is largely absent from current MS treatment algorithms. This review critically evaluates the existing pharmacogenomic literature across approved DMTs, highlighting reproducible findings, methodological limitations, and gaps that hinder clinical translation. We further discuss requirements for integrating pharmacogenomic markers into routine practice, emphasizing the need for large, multiethnic cohorts, standardized response definitions, and functional validation. Overall, these insights underscore both the potential and current limitations of pharmacogenomics in advancing precision medicine for MS.",

Nicotine-derived nitrosamine ketone (NNK), a potent tobacco-specific nitrosamine, has been implicated in MS; however, its mechanistic contribution to disease pathogenesis remains poorly understood. Here, we applied an integrative multi-level approach to investigate the potential role of NNK in MS. Mendelian randomization (MR) analysis identified genetically predicted dipeptidyl peptidase-4 (DPP4) activity as being associated with MS susceptibility. Molecular docking further demonstrated feasible interactions between NNK and candidate proteins, including DPP4, providing theoretical plausibility for chemical-protein interactions. In experimental autoimmune encephalomyelitis (EAE) mice, systemic NNK exposure accelerated disease onset, aggravated neurological deficits, and enhanced immune cell infiltration and demyelination within the central nervous system (CNS), accompanied by increased DPP4 expression in inflamed regions. Consistent with these observations, in vitro NNK treatment impaired endothelial barrier integrity in bEnd.3 cells by reducing tight junction proteins (ZO-1, Claudin-5, and Occludin) and upregulating adhesion molecules (VCAM-1 and ICAM-1). NNK exposure also triggered inflammatory activation in BV2 microglia, resulting in elevated expression of TNF-\u03b1, IL-1\u03b2, and IL-6. Importantly, DPP4 silencing partially restored endothelial junctional integrity and attenuated pro-adhesive signaling in endothelial cells while reducing inflammatory cytokine expression in microglia, suggesting that DPP4 is functionally involved in NNK-induced neurovascular inflammation. Together, these findings suggest that NNK exposure may modulate neuroinflammatory processes relevant to MS through blood-brain barrier (BBB) disruption and microglial activation, with DPP4 potentially being involved in this process. This study provides mechanistic insights into how smoking-associated toxins may influence MS progression and highlights DPP4-related pathways as potential targets for therapeutic investigation.",

In an approach to better elucidate the mode of action of teriflunomide in the central nervous system (CNS), we aimed here to clarify the role of teriflunomide on glial cells using an ex\u00a0vivo demyelination model. Organotypic cerebellar slice cultures (OSC) were cultivated from 10-day-old mice and left to fully myelinate for another 7\u2009days. Demyelination was induced by lysolecithin (LPC) and was studied by immunohistochemistry against myelin proteins and electron microscopy. Glial cell responses were investigated by immunohistochemistry. Intra-glia interactions were studied using primary rodent glial cell cultures. Teriflunomide treatment did not affect developmental myelination but attenuated myelin degradation induced by LPC, as assessed by myelin basic protein and myelin oligodendrocyte glycoprotein immunoreactivity. During demyelination, teriflunomide treatment was associated with reduced microglial cell density and proliferation. Partial depletion of microglia using the CSF-1R inhibitor BLZ945 resulted in a similar preservation of myelin, supporting a functional association between microglial abundance and the extent of myelin loss in this model. Quantitative ultrastructural analysis further supported preserved myelin structures in teriflunomide-treated slices. Spontaneous remyelination was improved and enhanced numbers of oligodendrocytes were detected following teriflunomide treatment in OSC. However, direct cytoprotective/pro-proliferative effects of teriflunomide on oligodendroglia were not observed in primary glial cultures. There were also no indirect effects of teriflunomide-treated microglia on oligodendrocyte progenitor cells in\u00a0vitro. Teriflunomide exerts beneficial effects on myelin preservation and remyelination in an ex\u00a0vivo demyelination model, potentially through modulation of glial cell dynamics rather than direct effects on oligodendroglial cells.",

The disease exhibits considerable heterogeneity in clinical progression, with some patients experiencing more aggressive disease activity and a rapid decline in quality of life. Vitamin D plays a key role in immune regulation, and evidence suggests that its deficiency constitutes a significant environmental risk factor for immune-mediated conditions such as MS. While there are controversies regarding the role of serum 25(OH)D in MS as well as vitamin D3 supplements in controlling relapse and disability improvement during treatment. Therefore, our current meta-analysis aims to examine the relationship between serum 25(OH)D levels-and their modulation through supplementation-and multiple sclerosis. Comprehensive literature review was performed from conception to November 17, 2025, employing various online databases including PubMed, Cochrane Library, Web of Science, and EMBASE. The relevant studies about MS and serum 25-hydroxyvitamin D (25(OH)D) level or vitamin D3 supplementation. This meta-analysis incorporated 40 research examining the correlation between serum 25(OH)D levels and multiple sclerosis, as well as 22 studies investigating the effects of vitamin D3 supplementation on multiple sclerosis. 1) The 25(OH)D levels in patients with MS were significantly lower than those in healthy controls. In the analysis of disease subtypes, patients with relapsing-remitting MS (RRMS) had significantly higher 25(OH)D levels than those with secondary progressive MS (SPMS), but no significant difference was observed compared to patients with primary progressive MS (PPMS). Additionally, RRMS patients had significantly lower 25(OH)D levels during relapse than during remission. No significant seasonal fluctuation in 25(OH)D levels was observed in MS patients; 2) Multivariable-adjusted analysis comparing the highest versus lowest serum 25(OH)D categories revealed that higher serum 25(OH)D levels were associated with a lower risk of MS onset and lower disability scores (EDSS), but no significant association was found with disease activity. 3) In the intervention analysis, overall, vitamin D3 supplementation did not significantly reduce the annualized relapse rate (ARR) or improve EDSS scores. However, subgroup analysis indicated that high-dose vitamin D3 supplementation significantly reduced the ARR, whereas low-dose supplementation showed no\u00a0such effect. Multivariable-adjusted analysis further confirmed that vitamin D3 supplementation was significantly associated with a reduced risk of MS\u00a0relapse, and this benefit was similarly observed only in the high-dose supplementation group. This systematic analysis confirms that patients with MS exhibit significantly lower serum 25(OH)D levels compared to healthy controls, with notable reductions observed during clinical relapses. A clear gradient exists across disease subtypes, with RRMS patients showing higher levels than those with SPMS. An inverse correlation was demonstrated between serum 25(OH)D levels and both the risk and severity of MS. Critically, while high-dose vitamin D3 supplementation is associated with a reduced ARR and overall relapse risk, neither supplementation compared to placebo nor dosage comparison significantly affected relapse rates during the study period or final disability scores. These findings suggest a complex, dose-dependent role of vitamin D in modifying relapse risk without a clear impact on short-term disability progression in established MS. https://www.crd.york.ac.uk/PROSPERO/login, identifier CRD420251273119.",

This review examines modifiable non-infectious determinants across the life course and proposes integrated prevention strategies. Key factors include vitamin D deficiency, low UV exposure, smoking, adolescent obesity, air pollution, and chemical environmental exposures. Mendelian randomization studies support the causality of several determinants, particularly low vitamin D and high BMI. Adolescence emerges as a critical susceptibility window where the maturing immune system is uniquely sensitive to metabolic and environmental triggers. Among validated interventions, vitamin D supplementation stands out for its ability to reduce disease activity in early MS. Effective prevention requires both individual actions and structural public health policies, such as air quality regulations and urban \"walkability\". Future efforts should prioritize multimodal strategies targeting high-risk youths through the educational system (physical activity, weight management, and smoking prevention). These holistic approaches offer broad-spectrum benefits, reducing the burden of MS while preventing comorbidities, including cardiovascular, metabolic but also cancer.",

It is now being considered in clinically isolated syndrome (CIS) prior to MS. In the D-Lay MS clinical trial, supplemental vitamin D3 reduced disease activity in CIS and the early stages of relapsing-remitting (RR) MS without causing any serious adverse events. The race/ethnicity of participants is not given in D-Lay MS and should be included in future studies of vitamin D supplementation in CIS. It will be of interest to investigate the long-term effects of supplementation, initially given in CIS, on the disease and physical activity associated with the progression to RRMS. Interferon beta and teriflunomide are effective in CIS, and due to their different mechanisms of action to vitamin D, may have additive effects with the supplement. As vitamin D supplementation is associated with low or no adverse effects, this supplementation should be considered further in clinical trial and in real life treatment of CIS.",

We used data from a Swedish population-based case-control study (2386 cases, 4849 controls) to investigate the association between dental amalgam exposure and MS risk. Odds ratios (ORs) with 95% confidence intervals (CIs) were estimated by using logistic regression and interaction with smoking was evaluated. Relapsing-onset MS cases born between 1965 and 1985 (n\u2009=\u20091191) were followed longitudinally by using clinical data from the Swedish MS registry. The time to confirmed disability worsening (CDW) and Expanded Disability Status Scale (EDSS) 3 and 4 were assessed by using Cox regression; EDSS trajectories were analysed by using linear mixed-effects models. Amalgam exposure was associated with increased MS risk in a dose-dependent manner (OR for trend 1.14, 95% CI 1.08-1.20). A significant interaction with smoking was observed (attributable proportion due to interaction 0.25, 95% CI 0.10-0.40). In the longitudinal cohort, those with at least six fillings had increased risk of CDW [hazard ratio (HR) 1.35, 95% CI 1.07-1.71] and progression to EDSS 3 (HR 1.48, 95% CI 1.07-2.05) and EDSS 4 (1.68, 95% CI 1.01-2.83). Associations were stronger among current smokers, those diagnosed after age 40\u00a0years, and individuals on low-efficacy therapies. The EDSS trajectories also showed faster progression in the high-exposure group (P\u2009=\u2009.044). Dental amalgam exposure may be associated with both increased risk of MS and faster disability progression. Findings support a potential synergistic effect with smoking and raise the hypothesis that mercury may contribute to MS-related neurodegeneration.",

Traditionally approved for osteoporosis and breast cancer prevention, its tissue-selective estrogen receptor modulation underpins its potential therapeutic applications. This review critically examines the pharmacological, preclinical, and clinical evidence supporting raloxifene's neuroprotective and neuropsychiatric effects, as well as its mechanisms of action, safety profile, and clinical limitations. Raloxifene exerts neuroprotective effects by targeting estrogen receptors, including ER\u03b1, ER\u03b2, and GPER, modulating genomic and non-genomic pathways. These pathways regulate oxidative stress, mitochondrial stability, neuroinflammation, and apoptosis-core features of neurological disorders such as Alzheimer's (AD), Parkinson's (PD), Multiple sclerosis (MS), and Amyotrophic lateral sclerosis (ALS). Preclinical studies demonstrate raloxifene's ability to reduce amyloid-\u03b2 aggregation in AD, protect dopaminergic neurons in PD, mitigate demyelination in MS, and decrease protein aggregation in ALS. Additionally, raloxifene exhibits positive effects on memory, attention, and negative symptoms in schizophrenia, alongside antidepressant and anxiolytic properties. Although promising, raloxifene's clinical translation faces challenges. Existing trials are limited by small sample sizes, heterogeneous designs, and a lack of long-term data. Most studies focus on postmenopausal women, leaving gaps regarding effects in men, premenopausal women, and younger populations. Furthermore, discrepancies between preclinical and clinical dosing complicate its therapeutic optimization. Future research should explore sex-specific effects, optimize CNS-targeted dosing strategies, and employ biomarkers for neuroprotection and inflammation. Long-term trials are essential to evaluate its disease-modifying potential. Raloxifene represents a promising repurposing candidate for CNS disorders, however, its therapeutic role remains to be established through robust clinical validation.",

The evolving landscape of immunotherapies has made treatment decisions more complex, yet also opened opportunities for therapies targeting shared immunopathogenic mechanisms. However, evidence for this patient group remains limited to case reports and small series. In this multicenter observational study, 420 MS patients were screened, identifying 38 with PsO. These were compared with MS-only patients regarding demographics, disease course, Expanded Disability Status Scale (EDSS), and disease-modifying therapy (DMT) use. DMT histories, reasons for discontinuation, and adverse events were analyzed. Logistic regression assessed PsO and MS worsening, using dimethyl fumarate (DMF) as reference. MS/PsO patients were older at diagnosis (37.6 vs. 33.0 years). EDSS and disease course showed no statistically significant differences. DMF was most frequently used (68%), with low rates of PsO (8%) and MS worsening (15%). PsO worsening was common under teriflunomide (75%), interferons (38%), and sphingosine-1-phosphate (S1P) modulators (40%). Logistic regression suggested higher odds under teriflunomide (OR = 16.5, p = 0.028), interferons (OR = 16.5, p = 0.004), and S1P-modulators (OR = 8.25, p = 0.047). Anti-CD20 therapies (OR = 2.75, p = 0.257) and natalizumab (OR = 1.83, p = 0.635) showed non-significant trends. Interleukin-17 (IL-17) inhibitors were well tolerated, with >50% stable in both conditions and no significant MS worsening (OR = 1.67, p = 0.546). IL-17 inhibitors and DMF showed a favorable tolerability in MS/PsO. Teriflunomide, interferons, and S1P-modulators frequently exacerbate PsO. CD20 therapies and natalizumab remain effective for MS but may worsen PsO; IL-17-based combinations appear promising in highly active disease.",

It was hypothesized that the geographic variation of mortality from SLE would reveal a similar pattern as Hodgkin lymphoma (HL), multiple sclerosis (MS), Crohn's disease (CD), and ulcerative colitis (UC).MethodsUsing the vital statistics of 21 countries from 1951-2022, overall and age-specific death rates from the 5 diseases were calculated for each individual country. The death rates of different countries were compared using linear regression analysis.ResultsWhereas other autoimmune diseases or diseases associated with an underlying EBV infection, such as HL, MS, CD, and UC, showed remarkably similar geographic variations, the geographic distribution of SLE did not fit this overall pattern. High death rates from SLE were not clearly associated with developing versus developed countries, northern versus southern latitude, or any specific continent. However, similar geographic distributions of SLE were consistently found among consecutive age groups, ranging from 0-4 to 85+ years.ConclusionsThe similarities in the geographic distributions of death rates from HL, MS, CD, and UC suggest that these 4 diseases share a set of one or more common environmental risk factors. Other environmental risk factors besides EBV infection must contribute to the varying occurrence of SLE across the globe. These risk factors start exerting their influence at a very young age of less than 5\u00a0years.",

This study conducted in-depth forced degradation studies of siponimod in solid state subjected to acidic, alkaline, oxidative, photolytic, and thermal conditions, in compliance with ICH guidelines Q1A (R2) and Q3A (R2). An HPLC method was developed to quantify siponimod and separate its degradation products (DPs). The DPs were characterized using LC-HRMS/MS and LC-MSn techniques. Moreover, the toxicological profiles of siponimod and its DPs were evaluated through the in silico tools ProTox 3.0 and ADMETlab 3.0, with molecular docking and dynamics simulations assessing their binding to the S1P1 receptor. Siponimod was stable to light but degraded under acidic, alkaline, oxidative, and thermal stress, producing five products: DP-1 (acidic), DP-2/3 (oxidative), DP-4 (hydrolytic), and DP-5 (thermal). The toxicity prediction suggested that neither siponimod nor its DPs exhibited carcinogenic or mutagenic potential, and the molecular modeling analysis revealed that DP-2 and DP-3 demonstrated favorable binding affinities, with stable dynamic profiles and thermodynamic properties that closely resembled those of siponimod. As far as we know, this is the first study on the structural elucidation of the DPs of siponimod by LC-HRMS/MS and LC-MSn.",

Furthermore, a predictive model for blood-brain barrier (BBB) permeability (logBB) was developed. Using 1246 experimental SFE measurements from the Minnesota Solvation (MNSol) database, we parametrized the solvent accessible surface area (SASA) nonpolar term for 27 organic solvents, enabling PBSA calculations in a broad set of solvent environments. Across the MNSol data set, PBSA achieves an overall root-mean-square error (RMSE) of 1.10 kcal/mol, compared with 0.98 kcal/mol from quantum mechanical SMD calculations at the B3LYP/6-31G* level. To assess parameter transferability, we computed water-organic solvent logP values for 248 compounds spanning five solvent systems; PBSA yields an overall RMSE of 2.02 log units, slightly higher than the SMD result of 1.5 log units. Finally, we developed a quantitative model for BBB permeability (logBB) using multivariable linear regression based on PBSA-derived hydration free energies and selected organic-solvent SFEs. The model shows stable predictive performance on both the training (N = 865) and test (N = 97) sets, with RMSE \u2248 0.65 log units and MAE \u2248 0.5 log units, and demonstrates improved rank ordering on the test set (Kendall's tau = 0.45). Overall, this work extends PBSA applicability to a wide range of solvents and establishes physically motivated and computationally efficient approaches for predicting some key ADMET descriptors.",

We investigated the differences in DMT use between LOMS and AOMS within the French MS registry at comparable levels of disease severity. This retrospective cohort study used data extracted in December 2024 from the French MS registry on patients with relapsing-remitting onset MS between 1997 and 2023. The primary outcome was the annual probability of receiving a DMT according to age at MS onset, adjusted for disease severity. Secondary outcomes included the annual probability of receiving a highly effective DMT (HEDMT), each DMT separately, having \u22651 EDSS measurement, having \u22651 brain MRI, and DMT initiations and discontinuations. We used a longitudinal logistic model with generalized estimating equations and an inverse-probability-of-censoring weighting. A total of 36,148 were included patients; 26,540 (73.4%) were female, mean age was 33.5 years (SD, 9.7), and 2,308 (6.4%) were aged \u226550 at disease onset. Median follow-up was 10.8 years (interquartile range, 5.6-17.0). Patients with LOMS had a lower annual probability of receiving a DMT compared with patients with AOMS (73.7% vs 83.1%; odds ratio [OR], 0.57 [95% CI 0.52-0.62]). The difference was greater for HEDMT (24.6% vs 44.4%; OR, 0.41 [95% CI 0.36-0.46]). Patients with LOMS were more likely to receive teriflunomide and less likely to receive fumarates, S1PR modulators, natalizumab, or anti-CD20. Clinical and radiologic follow-up did not differ significantly between patients with LOMS and AOMS. The rate of DMT initiation was lower in patients with LOMS (0.13 vs 0.17 initiation per patient-year). Although the proportions of DMT discontinuation were similar (59.7% vs 60.4%, excluding pregnancy-related discontinuations), these discontinuations were more often attributed to a complete discontinuation strategy (27.9% vs 22.3%) and less often to an escalation strategy (9.2% vs 13.8%) in patients with LOMS. At comparable levels of disease severity, patients with LOMS were less likely to be treated with DMTs, particularly HEDMT, than patients with AOMS. This gap was driven both by fewer DMT initiations and more frequent complete discontinuations.",

This narrative review examines the current evidence regarding the potential effects of RES on memory-related processes and neuroinflammatory biomarkers in major neurological disorders, including Alzheimer's disease (AD), Parkinson's disease (PD), multiple sclerosis (MS), and cerebral ischemia. Relevant literature was identified through searches of major scientific databases, and studies addressing the molecular mechanisms, experimental outcomes, and therapeutic implications of RES in these conditions were evaluated. The available evidence indicates that RES can modulate several biological pathways associated with neurodegeneration, including oxidative stress, inflammatory signaling, mitochondrial dysfunction, and neuronal survival. Experimental studies suggest that RES may influence key molecular mediators such as pro-inflammatory cytokines, nitric oxide (NO) signaling, and matrix metalloproteinases, which are implicated in neuronal damage and blood-brain barrier disruption. In preclinical models of AD and PD, RES has been associated with improvements in cognitive performance, reduction of neuroinflammatory markers, and attenuation of neuronal loss. Similarly, studies in MS and cerebral ischemia models indicate that RES may modulate immune responses, reduce oxidative damage, and limit ischemia-related neuronal injury. However, most of the current evidence derives from in vitro and animal studies, and clinical data remain limited. Moreover, the low bioavailability of RES and variability in dosing regimens represent important challenges for clinical translation. Therefore, although experimental findings support the potential neuroprotective role of RES, further well-designed clinical studies are required to determine its therapeutic relevance and safety in human neurological disorders. This narrative review was developed through a structured search of PubMed, Scopus, and Web of Science for articles published between 2000 and 2024, focusing on mechanistic, preclinical, and clinical investigations of RES in neurological disorders. This review synthesizes current evidence on the molecular and cellular mechanisms underlying the neuroprotective effects of RES, with particular emphasis on its antioxidant, anti-inflammatory, and immunomodulatory activities. By integrating findings from experimental and clinical research, the review highlights the potential of RES to modulate key pathways involved in neurodegeneration and neuroinflammation. Although further well-designed clinical studies are required to clarify its therapeutic efficacy and translational relevance, the available evidence supports continued investigation of RES as a promising candidate for neuroprotective strategies in neurological disorders.",

SUMOylation plays an important regulatory role in both innate and adaptive immunity. The natural compound anacardic acid (AA) has been shown to bind and inhibit the SUMO-activating enzyme E1, the first enzyme in the SUMOylation pathway. Here, we examined the consequences of AA treatment on the development of innate and adaptive immune responses in vitro and in vivo. We examined the inhibitory effects of anacardic acid on SUMOylation and de-SUMOylation both in vitro and in vivo. The in vitro studies on the effect of anacardic acid on the development of an immune response were conducted in RAW264.7 cells and na\u00efve or antigen-driven splenocytes. AA inhibited activation of NF-\u03baB by preventing SUMOylation of NEMO, a key requirement for activation of the canonical NF-\u03baB pathway. Stimulation of splenocytes with LPS, a known immunostimulant, resulted in reduced production of inflammatory mediators, including IL-12, IL-23, TNF-\u03b1, and iNOS, in the presence of AA. In antigen-primed lymphocytes stimulated with MOGp\u2083\u2085-\u2085\u2085, AA reduced the induction of IL-17, IFN-\u03b3, TNF-\u03b1, IL-6, and GM-CSF. Following transfer of MOGp\u2083\u2085-\u2085\u2085-primed lymphocytes into na\u00efve mice, AA treatment significantly reduced clinical paralysis and pathological CNS inflammation in experimental allergic encephalomyelitis (EAE), an animal model of multiple sclerosis. The ability of AA to inhibit NF-\u03baB-driven inflammatory response and CNS inflammation after autoreactive T cells are already primed and circulating suggests that AA may have therapeutic potential in established Th1/Th17-mediated inflammatory diseases.",

Deficiency in ABCD1 results in VLCFAs accumulation in many tissues, including the brain and spinal cord. Elevated VLCFA levels, specifically C26:0, are consistent biochemical markers of ALD and are implicated in the ALD pathogenesis. ALD disease is manifested by multiple phenotypes: the most severe cerebral disease (cerebral ALD, cALD), adrenomyeloneuropathy (AMN) and adrenal insufficiency (Addison disease). VLCFA accumulation is a hallmark of all ALD phenotypes, and reduction/normalization of VLCFA levels is an attractive approach for the treatment of all ALD manifestations. VLCFAs synthesis involves enzymes from elongase of very long-chain fatty acids (ELOVL) enzyme family with ELOVL1 being a rate-limiting enzyme in C26:0 synthesis, making ELOVL1 an attractive target for medical intervention in ALD via Substrate Reduction Therapy (SRT). In this paper, we describe the in vitro assays established to support medicinal chemistry efforts to develop small-molecule ELOVL1 inhibitors for ALD. Notably, we developed novel, breakthrough in vitro methods to monitor enzymatic and cellular ELOVL1 activity, enabling high-throughput screening (HTS) of Sanofi library collections. We successfully identified CNS-active, small-molecule ELOVL1 inhibitors shown to be efficacious in the reduction of C26:0 VLCFA levels in cells and multiple tissues, including brain and spinal cord, in animal models.",

Herein, we designed a highly organic-solvent-resistant imidazolium-grafted anion-exchange membrane (AEM) for NAFBs, realizing rapid anion hopping conduction in organic solvents. The membrane exhibited an ultrafast ionic conductivity as high as 2.1 mS cm-1 in DMF-based electrolyte which was much greater than that of the commercial Celgard membrane (only 0.45 mS\u00b7cm-1), coupled with exceptional barrier properties evidenced by ultralow active-species permeability values of 1.6 \u00d7 10-8 cm2 s-1 for 2,1,3-benzothiadiazole anolyte and 3.8 \u00d7 10-9 cm2 s-1 for 10-methylphenothiazine catholyte, respectively. Moreover, the membrane demonstrated outstanding stability in aggressive organic solvent, achieving an average energy efficiency (EE) over 66.1% for over 330 cycles at 5\u00a0mA cm-2 in a NAFB cell test, which far exceeded the commercial Celgard membrane (with only 70 cycles with an average EE of 48.8%).

A systematic review of existing clinical studies assessing the effects of aspirin/ acetaminophen on MS-related fatigue, thermoregulation, and exercise performance. Electronic databases including Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, PubMed, Scopus, Web of Science, Wiley, Google Scholar, and ClinicalTrials.gov were searched up to March 2024. Quality assessment was conducted using the Cochrane risk of bias tool 2. to evaluate the methodological rigor of included studies. Outcomes analyzed included clinically assessed fatigue scores, exercise endurance, and post-exercise thermoregulation, with attention to potential risks associated with aspirin use. After assessment of 57 reports for eligibility, only seven studies met inclusion criteria; results indicated that aspirin pretreatment significantly improved Time to Exhaustion (TTE) in heat-sensitive MS patients (p\u2009=\u20090.013), though one study reported no significant effect. Aspirin reduced post-exercise temperature rise by 56%, but this was not statistically significant in one trial (p\u2009=\u20090.178), while another showed significant reductions (p\u2009=\u20090.002). Aspirin and acetaminophen may offer benefits in alleviating fatigue, enhancing thermoregulation, and improving exercise endurance in MS patients. These findings suggest that nurses should consider the potential role of aspirin in symptom management, with further research needed to confirm efficacy and safety. This review highlights a potential adjunct therapy for nurses to incorporate into comprehensive MS care, emphasizing symptom control and quality of life improvements. Not applicable.

In this study, a green extraction strategy based on pressurized liquid extraction (PLE) was optimized to enhance the recovery of phenolic and flavonoid compounds from ABP using a response surface methodology. Extraction temperature and solvent composition were identified as the key factors driving extraction performance. Optimal conditions using a mixture of ethyl acetate and ethanol (90/10, v/v) at 180 \u00b0C significantly enhanced extraction yield, total phenolic and flavonoid content, and antioxidant activities, as measured by ORAC and DPPH assays. Chemical characterization via HPLC-C18-Q-TOF-MS/MS revealed a diverse profile of phenolic and flavonoid compounds, including caffeoylquinic acid derivatives and related transformation products. The neuroprotective potential of the optimized extract was further evaluated through in vitro inhibition assays targeting acetylcholinesterase (AChE), butyrylcholinesterase (BChE) and lipoxygenase (LOX), alongside a permeability assessment using an in vitro blood-brain barrier (BBB) model. Molecular docking simulations were performed to explore the interactions of apigenin-the most representative flavonoid in the optimal extract-with the three target enzymes. Overall, these findings support the valorization of ABP as a source of bioactive compounds and highlight the potential of PLE as an efficient and sustainable extraction approach.",

Similarly, epidemiological studies implicate numerous environmental risk factors in MS risk, but these cannot identify specific causal mechanisms. We review our current knowledge of genetic mechanisms in MS, including the critical role of expression quantitative trait locus (eQTL) mapping in translating genetic risk loci into causal mechanisms. Molecular and functional context has emerged as an important missing component of these studies, and we discuss how environmental risk factors can be modelled in a quantitative genetic context to identify disease mechanisms. In parallel, we highlight recent advances in which quantitative genetic methods establish a causal role for low vitamin D and obesity in MS, and to dissect the mechanisms through which these operate. As genetic, transcriptional, and epigenetic studies continue to expand, further mechanistic insights for MS are likely to come from the integration of genetic and environmental data.",

Reclassification-based exit rules may reduce misclassification bias. Manitoban administrative health data (1995-2022) were used to ascertain multiple sclerosis (MS) and \"juvenile diabetes\" (JD) prevalence. We constructed multivariable logistic regression model-based algorithms and used a model-predicted probability exit rule to reclassify JD and MS case status annually. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and reclassification rates were estimated. Linear regression tested for differences in prevalence estimates for the model-based algorithm with an exit rule and an existing Canadian Chronic Disease Surveillance System (CCDSS) algorithm without an exit rule. The MS cohort included 60 228 individuals (608 cases, 59 620 non-cases) and the JD cohort 44 125 individuals (2506 cases, 41 619 non-cases). Model-based algorithm sensitivity was 0.62 to 0.85 for MS and 0.87 to 0.95 for JD. PPV for MS was 0.21 to 0.60 and for JD was 0.92 to 0.95. Specificity and NPV were consistently high (0.98-1.00). Non-cases were frequently misclassified; reclassification rates for non-cases were higher than for cases for MS (0.22-0.33 vs. 0.14-0.28) and JD (0.18-0.65 vs. 0.13-0.15). The model-based algorithm with an exit rule for MS, but not for JD, had a slower increase in prevalence than the CCDSS algorithm. Case ascertainment algorithms with an exit rule can address misclassification bias when estimating chronic disease prevalence using administrative health data. Improvements are disease dependent.

Cross-sectional analysis of a multicentre prospective registry. Six German Social Accident Insurance hospitals distributed across Germany, providing standardised post-COVID assessments for individuals with persistent symptoms following occupational SARS-CoV-2 infection. Workers with confirmed SARS-CoV-2 infection recognised as an occupational disease or work-related accident who presented with persistent symptoms and were enrolled in a multicentre post-COVID registry. Cognitive and physical fatigue severity assessed using validated self-administered questionnaires (Fatigue Scale for Motor and Cognitive Functions, Modified Fatigue Impact Scale and W\u00fcrzburg Fatigue Inventory for Multiple Sclerosis). Clinical relevance was determined based on established cut-offs reported in the literature. Fatigue severity was operationalised using median splits of the respective subscales to identify factors associated with higher fatigue levels. Among 1511 registry cases, 628 participants had complete fatigue data. Median age was 54 years, 77% were female and most worked in nursing (43%) or educational/care professions (19%). Clinically relevant fatigue was highly prevalent: cognitive fatigue affected 78%-93% and physical fatigue 87%-98%. Both fatigue dimensions were positively correlated with older age, work incapacity and persistent symptom burden. In multivariate analyses, a higher number of acute symptoms was associated with lower odds of cognitive fatigue (adjusted OR 0.39, 95%\u2009CI 0.19 to 0.81), while physical fatigue remained associated with profession (adjusted OR 2.04, 95%\u2009CI 1.17 to 3.59). Sex, pre-existing conditions, hospitalisation and variant wave were not significant predictors in either model. Fatigue is a prevalent and disabling PCS-symptom among occupationally exposed workers. Distinct determinants of cognitive and physical fatigue emphasise the need for early recognition, targeted management and rehabilitation strategies to support recovery and work reintegration.",

BPA, BPS, and BPF have estrogen-like activity and affect hormone action, leading to developmental toxicity. Recent data have proven that BPA, BPS, and BPF affect Homeobox (HOX) gene expression, which is crucial for development and organogenesis. An extensive literature survey was conducted using Google Scholar and PubMed, including literature published until 2025. The literature search was performed using various keywords like \"Bisphenol A,\" \"Bisphenol F,\" \"Bisphenol S,\" \"homeobox genes,\" \"epigenetic regulation,\" and \"developmental toxicity\". From the literature survey, it was clearly proven that BPA and its derivatives have a high impact if exposed during fetal development. Epigenetic changes in HOX gene clusters, changes in histone modification patterns, and increased oxidative stress levels are major areas of concern regarding developmental toxicity, which can affect fetal development, including neural development, sexual differentiation, and bone formation, all of which are crucial for embryogenesis and organogenesis. The literature review revealed that BPA and its derivatives, though claimed to be safer, are as toxic as BPA and, in some instances, are even more toxic to the developing fetus. The mechanistic action of bisphenols and the dysregulation of HOX gene expression are important steps towards understanding the teratogenic potential of BPA and its derivatives. BPA, BPF, and BPS are major concerns for embryonic development, as these chemicals affect the regulation of HOX gene expression and the signaling pathways that are crucial for embryonic development. Regulatory action and the development of safer chemicals are important for the health and safety of the fetus and for reducing the potential for developmental hazards.",

Dysregulation of this transcription factor contributes significantly to autoimmune conditions such as psoriasis, rheumatoid arthritis, and multiple sclerosis. Consequently, inhibition of ROR\u03b3t has attracted considerable interest as a therapeutic approach for these disorders. In this study, we designed and synthesized a series of aryl sulfonyl derivatives as ROR\u03b3t inhibitors. Selected compounds were functionally characterized as inverse agonists, with compound 7 as the initial lead. Through a scaffold-hopping strategy and systematic structure-activity relationship (SAR) studies of key substituents, we identified potent ROR\u03b3t inhibitors with favorable oral bioavailability. Compound 8v emerged as the most promising candidate. In vivo pharmacokinetic studies demonstrated that 8v possessed good oral absorption. In addition, 8v showed moderate metabolic stability in human and mouse liver microsomes (t\u2081/\u2082\u00a0=\u00a045\u00a0min and 151\u00a0min, respectively). Furthermore, in a mouse model of LPS-induced systemic inflammation-where IL-17 elevation is mediated by T-cell activation-and in an IMQ-induced psoriasis-like dermatitis model, 8v significantly inhibited IL-17 secretion and ameliorated disease-related symptoms. Collectively, these results support the therapeutic potential of small-molecule ROR\u03b3t modulators for the treatment of inflammatory and autoimmune diseases.",

Stress granules (SGs), membraneless organelles formed via liquid-liquid phase separation (LLPS) in response to cellular stress, function as a cytoprotective mechanism against stress induced apoptosis and pyroptosis. SGs can counteract NLRP3 inflammasome by sequestering dead-box helicase 3 X-linked (DDX3X), thereby promoting the survival of pyroptotic cells. Here, we identified that plumbagin (PL), a natural naphthoquinone with antioxidant and anti-inflammatory properties, as a novel SG inducer. In microglia, PL induced SGs that suppressed NLRP3-mediated pyroptosis and subsequent mitochondrial dysfunction, with DDX3X as a potential target. Furthermore, PL alleviated neuroinflammation and demyelination and suppressed oxidative stress in the CNS of both the cuprizone (CPZ) and experimental autoimmune encephalomyelitis (EAE) mouse models. Our findings reveal that PL can mitigate neuroinflammation and myelin damage by modulating the DDX3X-SG axis, supporting a novel therapeutic strategy for MS.",

Here we identify a distinct population of foamy GPNMB+ microglia/macrophages associated with lesion expansion in secondary progressive MS. Using integrated lipidomic, transcriptomic, proteomic, chemical proteomic and histological analyses of human postmortem MS lesions, we show that lesions containing foamy microglia/macrophages exhibit disrupted lipid metabolism, lysosomal stress and markers associated with heightened phagocytosis and antigen presentation without classical pro-inflammatory signatures. These lesions are enriched for oxylipins, bismonoacylglycerolphosphates and cholesterol esters, and are associated with increased B cell infiltration and IgG1. Monoacylglycerol lipase (MAGL), a lipid-metabolizing enzyme enriched in lesions with foamy microglia/macrophages, emerged as a potential therapeutic target. Inhibition of MAGL promoted lesion recovery and reduced microgliosis in a mouse model of demyelination. Finally, oxylipins in cerebrospinal fluid correlate with the proportion of foamy lesions, suggesting potential biomarkers for progression. Our findings implicate disturbed lipid metabolism in chronic MS pathology and suggest that foamy microglia/macrophages are an interesting cell type to target for progressive disease.",

Although the precise cause of MS is unknown, previous studies have found a strong link between MS and certain viral infections, leading researchers to speculate that viruses may play a role in MS pathogenesis by acting as environmental triggers. We present a comprehensive review of viral associations with MS, focusing on viruses with strong evidence for involvement in disease development, including members of the Herpesviridae family-such as Epstein-Barr virus, human herpesvirus 6, varicella-zoster virus, herpes simplex virus 1, cytomegalovirus, and SARS-CoV-2. Those viruses appear to modulate the neuro-immunological system in genetically susceptible individuals, leading to immune-mediated demyelination. Viral exposure is thought to represent an early initiating or permissive event that triggers downstream immune dysregulation, ultimately leading to MS onset in predisposed hosts. Additionally, they can cause latent infections with episodes of reactivation, which might be associated with relapsing presentation of MS. Several theories have been proposed to explain the viral etiology of MS, including molecular mimicry, virus-induced inflammatory response, autoreactive T- and B-cell activation, and increased susceptibility to antigenic exposure. Besides addressing the current knowledge gap, we also highlight future research directions for effective MS management, including developing experimental models and conducting clinical trials, identifying specific biomarkers, and investigating novel antiviral agents. An improved understanding of MS etiology and the role of viruses in its physiopathology may enable more targeted interventions and better treatment outcomes.",

This population-based cohort study used data on pregnancies from primary care practices that contributed to the UK Clinical Practice Research Datalink (CPRD) database (Gold and Aurum) between 2000 and 2022, linked to Hospital Episode Statistics (HES). Modified Poisson regression with robust standard errors estimated adjusted relative risks (aRR) and 95% confidence intervals (95% CI) assessing the association between 17 autoimmune diseases and 12 pregnancy outcomes, selected following literature review and expert consultation. Models were adjusted for demographic and comorbidity variables. Findings were evaluated using the Benjamini-Yekutieli procedure to control for multiple testing across autoimmune disease-outcome associations. A total of 5,239,383 pregnancies from the CPRD pregnancy register and 2,485,366 births recorded in HES maternity data met the eligibility criteria. Women with autoimmune diseases had an increased risk across all pregnancy outcomes examined. Among antenatal outcomes, markedly elevated risks were observed for hyperemesis gravidarum in Addison's disease (aRR 3.72, 95% CI 2.48-5.59), miscarriage in Sj\u00f6gren's syndrome (1.66, 1.02-2.70), gestational hypertension in type 1 diabetes mellitus (T1DM; 2.95, 2.77-3.15), pre-eclampsia/eclampsia in T1DM (3.56, 3.32-3.82), and gestational diabetes mellitus in Graves' disease (1.37, 1.21-1.54). For obstetric outcomes, increased risks were observed for caesarean birth in inflammatory bowel disease (IBD; 1.27, 1.22-1.31), small for gestational age in systemic lupus erythematosus (SLE; 2.45, 1.65-3.62), preterm birth in rheumatoid arthritis (1.53, 1.33-1.76), and stillbirth in SLE (1.82, 1.12-1.84). Perinatal mental health outcomes were more common across several autoimmune diseases, with particularly high risks in myasthenia gravis (anxiety 3.05, 1.89-4.92; depression 1.77, 1.37-2.28), SLE (anxiety 2.11, 1.67-2.67; depression 1.36, 1.22-1.53), and multiple sclerosis (anxiety 1.76, 1.38-2.23; depression 1.94, 1.77-2.12). Inverse associations were observed for hyperemesis gravidarum in systemic sclerosis, SLE, and myasthenia gravis, and for hypertensive disorders of pregnancy in multiple sclerosis. After Benjamini-Yekutieli correction for multiple testing, the number of statistically significant associations was reduced, with a core set of robust associations persisting across selected autoimmune diseases particularly, T1DM, SLE, Graves' disease, IBD and key pregnancy outcomes. Autoimmune diseases were associated with increased risks across a wide range of adverse pregnancy outcomes, with marked heterogeneity between individual conditions. This study provides adjusted relative risks across multiple domains of pregnancy outcomes including antenatal (e.g. miscarriage, hyperemesis gravidarum, gestational hypertension, pre-eclampsia, gestational diabetes), obstetric (e.g. preterm birth, caesarean birth, small for gestational age, stillbirth), and perinatal mental health outcomes (anxiety and depression), for both common and less frequently studied autoimmune diseases.

The primary analysis assessed the odds of having OSA in patients with and without AD. Additionally, we examined the rates of tonsillectomy and the likelihood of post-tonsillectomy bleeding in OSA patients with and without AD. 160,517 patients with AD were matched with 160,517 patients without AD. Mean age is 4.2 years and mostly female (81,157, 50.6%). AD patients were significantly more likely to have OSA (OR\u202f=\u202f2.283\u202f\u00b1\u202f0.08, p\u202f<\u202f.0001). Strongest associations were found with necrotizing vasculopathy (OR\u202f=\u202f3.571\u202f\u00b1\u202f0.87), connective tissue disease (OR\u202f=\u202f3.103\u202f\u00b1\u202f0.30), multiple sclerosis (OR\u202f=\u202f3.037\u202f\u00b1\u202f1.07), systemic lupus erythematosus (OR\u202f=\u202f2.644\u202f\u00b1\u202f0.83), rheumatoid arthritis (OR\u202f=\u202f2.406\u202f\u00b1\u202f0.68), and ulcerative colitis (OR\u202f=\u202f2.377\u202f\u00b1\u202f0.45) (p\u202f<\u202f.001 for all). OSA patients with AD were less likely to undergo tonsillectomy (3752 (39.7%) vs. 3975 (42.0%), OR\u202f=\u202f0.91\u202f\u00b1\u202f0.05, p\u202f=\u202f.001) but faced a higher post-tonsillectomy bleeding risk (232(5.7%) vs. 177(4.4%), OR\u202f=\u202f1.33\u202f\u00b1\u202f0.24, p\u202f=\u202f.005). Children with AD are more likely to have OSA than children without AD, emphasizing the need for careful management, especially when surgical options are considered.",

Beyond clinical variables, evidence suggests that environmental data can help capture disease trajectories. We investigated whether personal environmental measures can be organized into stable patterns that inform prognosis. In a multicenter cohort, 293 patients with MS or ALS were equipped with Atmotube air-quality sensors. We normalized volatile organic compound (VOC) time series and computed Dynamic Time Warping distances to capture temporal similarity. Hierarchical clustering yielded five daily exposure clusters, which were profiled using Atmotube variables (season, day type, humidity, temperature) and patient self-reports (work status, time outdoors), and evaluated by day-level differences between personal and fixed-station variables. These clusters can support interpolation of missing wearable intervals and generation of context-aware exposure estimates, thereby strengthening environmental inputs for prognostic modeling in MS and ALS.",

In developed countries, individuals spend a substantial proportion of time indoors. Therefore, the indoor exposome provides a unique framework to examine factors driving the increase in the rates of food allergy. This review summarizes epidemiological and mechanistic evidence of the indoor exposome, consisting of the combined exposures to food antigens, microbes, and chemicals encountered in indoor environments during early life, and their influence on food allergy development. Indoor house dust contains detectable food allergens, which remain biologically active and may be linked to non-oral exposure, leading to allergic sensitization. In contrast, early-life exposures to diverse microbes and their products are associated with protection from allergic disease. Emerging evidence further demonstrates that indoor chemicals, including detergents, plasticizers, and pollutants, can disrupt epithelial barrier integrity or function as immune adjuvants, thus increasing susceptibility to food sensitization. Collectively, these findings highlight the indoor exposome as a complex and important determinant of food allergy risk. Improved understanding of how the indoor exposome influences food allergy development may inform future primary prevention or intervention strategies.",

The cuprizone model provides a well-established experimental system for studying these processes. The apelinergic system, including the apelin receptor (APLNR), has been implicated in neuroprotection and central nervous system homeostasis. However, its role in white matter demyelination and repair remains incompletely understood. This study aimed to characterize the spatial and temporal dynamics of APLNR expression in relation to oligodendrocyte lineage cells in the corpus callosum (CC) during demyelination and remyelination. Demyelination was induced in 8-week-old C57BL/6 mice by 0.2% cuprizone supplementation in their drinking water for 5 weeks, followed by 5 weeks remyelination phase after toxin withdrawal. Histological assessment using Luxol Fast Blue/Cresyl violet staining was performed to evaluate structural changes in the CC. Immunohistochemistry and confocal microscopy were used to analyze APLNR expression, GST-\u03c0+ cells, and NG2+ cells, including their spatial distribution and co-localization. Quantitative analyses and correlation tests were conducted to assess relationships between cellular markers and CC area. Demyelination resulted in significant reduction in CC area and a marked decrease in GST-\u03c0+ cells, accompanied by a robust increase in NG2+ cells, while remyelination led to partial structural and cellular recovery. APLNR expression increased progressively from control to demyelination and further during remyelination, exhibiting pronounced regional heterogeneity with higher levels in lateral CC regions. Confocal analysis demonstrated increasing co-localization of APLNR with NG2+ cells, particularly during remyelination. Correlation analyses identified GST-\u03c0+ cell density as the strongest predictor of CC area, whereas APLNR showed phase-dependent associations, including a positive correlation with GST-\u03c0+ cells during remyelination and a negative relationship with NG2+ cells during demyelination. APLNR expression is dynamically regulated during cuprizone-induced demyelination and remyelination and is closely associated with oligodendrocyte lineage cell responses. Its increased expression and enhanced co-localization with NG2+ cells during remyelination suggest a potential role in endogenous repair processes. However, as the findings are based on descriptive analyses, further functional studies are required to determine the mechanistic contribution of APLNR signaling and its potential as a therapeutic target in demyelinating diseases.",

The etiologies of pediatric cancer are largely\u00a0unknown, but environmental pesticide exposures are likely to contribute. Chronic low-dose exposure to pesticide mixtures through drinking water is a growing concern in agricultural communities. This review examines epidemiological studies published between January 1980 and September 2022 that have evaluated the relationship between pesticide exposure and the risk of childhood brain tumors and leukemia. Exposures to pesticides used in the home or ingested through drinking water, residential proximity to agricultural areas where pesticides are used, parental pesticide exposure, and metabolic genotypes are discussed. Findings have shown increased risks for childhood cancers in areas of high agricultural crop density, which may imply a link to increased pesticide applications and pesticide drift from neighboring farm fields.\u00a0Noted\u00a0knowledge gaps include the contribution of genetics, exposure through drinking water, individual-level exposures, and pesticide mixtures to the risk of pediatric cancer.

Cumulative lifetime exposures (i.e. the exposome) contribute to ILD onset and progression by interacting with genetic susceptibility and influencing multiple molecular pathways. This review summarizes current evidence evaluating how environmental exposures interact across the genome, epigenome, transcriptome, proteome, metabolome, and microbiome to drive ILD pathogenesis. Environmental exposures, including air pollution, influence ILD risk through interactions with genetic factors that modify disease susceptibility. Epigenetic mechanisms, particularly DNA methylation, reflect key pathways through which exposures may contribute to ILD onset and progression and serve as sensitive biomarkers of environmental injury. Exposure-associated molecular alterations can be detected across multiple omic layers, including transcriptomic, proteomic, and metabolomic profiles. In parallel, exposures like cigarette smoking, silica, and air pollution influence the respiratory microbiome, with potential downstream effects on immune responses and fibrogenesis. Integrating these findings highlights environmentally-sensitive pathways that may represent novel targets for therapeutic modulation. Integration of exposomic and multiomic molecular frameworks offers new opportunities to improve ILD risk stratification, prognostication, and precision therapeutic development, while also strengthening our mechanistic understanding of environmentally-mediated disease.",

This retrospective single-center cohort study included pediatric NIU patients treated with TNF-\u03b1 blockers who had undergone brain magnetic resonance imaging (MRI) at any time during the course of the disease. Demographic and clinical characteristics, the ocular complication score (OCS), and imaging data were reviewed. The study cohort included 45\u00a0patients with a mean age of 13.8\u00b14.46 (5-22)\u00a0years. The mean duration of TNF-\u03b1 blocker treatment within the study period was 44\u00b127.9\u00a0months. The OCS did not significantly change from baseline to final visit (P=0.10). Brain MRI was performed before initiation of TNF-\u03b1 blocker therapy in 21 (46.6%) patients and during treatment in 24 (53.4%). All demyelinating lesions were detected on MRIs obtained after TNF-\u03b1 blocker initiation (median: 52\u00a0months; range 18-84). Central nervous system (CNS) demyelinating lesions were identified in 4 (8.8%) patients; two were diagnosed with multiple sclerosis, and two with radiologically isolated syndrome. CNS demyelination was uncommon but clinically relevant in pediatric NIU patients receiving TNF-\u03b1 blockers. Demyelinating lesions may be associated with pars planitis, neurologic symptoms, and/or a family history of demyelinating disease.

These pathological processes are closely associated with phosphodiesterase-4 (PDE-4) activity. Roflumilast (ROFL), a selective PDE-4 inhibitor, has demonstrated neuroprotective effects in various central nervous system disorders. However, its specific role in MS pathogenesis remains to be fully elucidated. This study aims to investigate the effects of ROFL on oligodendrocyte maturation, microglial polarization and the impact on protein kinase A/cAMP-response element binding protein pathway. An MS model was induced in mice via dietary administration of cuprizone (CPZ) for 7 days, starting with 0.7% (w/w), followed by 0.2% for 5 weeks. Beginning in week 5, mice received ROFL (5\u2009mg/kg/day, p.o) for 2 weeks. ROFL improved the motor abnormalities in the rotarod and open field tests. Together, ROFL downregulated the PDE4/cAMP-dependent pathway, exerting anti-inflammatory effects by suppressing NF-\u03baB and TNF-\u03b1. Additionally, microglial polarization shifted toward the anti-inflammatory M2 phenotype, with CD163 increment, in contrast to the pro-inflammatory M1 marker CD83. Furthermore, ROFL's antioxidant capacity was evidenced by reduced malondialdehyde levels, replenishment of glutathione levels, and reduced phosphorylation of ERK1/2. Oligodendrocyte differentiation and maturation were enhanced, as indicated by elevated levels of proteolipid protein, myelin-associated glycoprotein, CNPase, and myelin basic protein. Remyelination was confirmed through Luxol fast blue staining, accompanied by reduced apoptotic marker, caspase-3, in oligodendrocytes. Collectively, these findings suggest that ROFL exerts neuroprotective effects and highlight the therapeutic potential of PDE-4 inhibition as a strategy for MS treatment.",

This study investigates the potential role of adenotonsillectomy in pediatric-onset multiple sclerosis (POMS) risk and relapse rate. POMS participants and controls were recruited from 16 pediatric MS clinics between 1 November 2011 and 1 July 2017. Clinical and demographic information, including history of adenotonsillectomy, EBV serostatus, and HLA-DRB1*15:01:01 status, were collected. Multivariable logistic regression assessed the association between adenotonsillectomy and MS risk. In addition, negative binomial regression offset by follow-up time was used to assess the relationship between adenotonsillectomy and relapse rate in POMS participants with available follow-up data. The case-control analysis included 359 POMS participants and 560 pediatric controls. Individuals with a history of adenotonsillectomy had a 63% increased odds of MS (adjusted odds ratio (OR)\u2009=\u20091.63, 95% confidence interval (CI)\u2009=\u20091.01-2.64, p\u2009=\u20090.046).

This study aimed to evaluate the possible association between urinary heavy metals (HMs) concentration and the risk of childhood acute lymphoblastic leukemia (C-ALL) in children. The effects of socio-environmental factors also were investigated. In this case-control study, urinary concentrations of selected HMS were determined in urine samples of 124 children with acute leukemia (cases) and 104 healthy controls using ICP-OES. The social, economic, and environmental characteristics of participants were collected by a questionnaire. Multifactorial logistic regression models were applied to investigate the associations after adjustments for confounding factors. The creatinine-adjusted urinary concentrations of arsenic, cadmium, and lead in cases were significantly higher than healthy controls (the concentrations of nickel, chromium, and selenium were not significantly different). Multifactorial logistic regression in different adjusted models showed that the higher urinary concentrations of arsenic, lead, and cadmium increased the risk of C-ALL up to 2.5, 2.73, and 2.37 times, respectively. Urinary levels of Cd also showed a significant correlation with the risk of ALL. Among the socio-environmental risk factors, living near roads with heavy traffic, distance of living location from industrial zones, parental smoking, and consumption of rice as a staple food significantly increased the risk of C-ALL.

Oxidative stress has been proposed as a key mediator linking occupational exposure to impaired sperm morphology and function. This study aimed to evaluate the association between occupational exposure to chemical solvents and toxic metals and alterations in sperm function, with particular emphasis on oxidative stress-mediated pathways. In this case-control study, semen samples were collected from teratozoospermic men occupationally exposed to chemical solvents and heavy metals (n\u2009=\u200960) and from age-matched normozoospermic controls without known occupational exposure (n\u2009=\u200930). Standard seminal parameters were assessed according to WHO guidelines. Oxidative stress status was evaluated by measuring reactive oxygen species (ROS) and malondialdehyde (MDA) levels, along with antioxidant defense markers, including superoxide dismutase (SOD), catalase, and reduced glutathione (GSH). Sperm functional integrity was assessed through acrosome integrity assays and sperm DNA fragmentation (SDF), evaluated using the comet assay and flow cytometry. Levels of toxic metals (cadmium, lead, and chromium) were quantified using atomic absorption spectrophotometry. Occupationally exposed teratozoospermic men exhibited significantly elevated oxidative stress markers, with increased ROS levels (32.0\u2009\u00b1\u20099.0 vs. 15.0\u2009\u00b1\u20095.0) and MDA concentrations (4.8\u2009\u00b1\u20091.1 vs. 2.1\u2009\u00b1\u20090.6 nmol/mL), accompanied by a marked reduction in antioxidant defense markers (SOD, catalase, and GSH; p\u2009<\u20090.05) compared with controls. The proportion of acrosome-intact spermatozoa was significantly lower in exposed men (38.3%\u2009\u00b1\u20099.2% vs. 62.4%\u2009\u00b1\u200910.1%). Both comet assay and flow cytometric analyses demonstrated significantly higher levels of sperm DNA fragmentation in the exposed group. Furthermore, quantitative analysis revealed significantly elevated body burdens of cadmium, lead, and chromium among occupationally exposed individuals. These findings indicate that oxidative stress represents a central pathophysiological mechanism linking occupational exposure to chemical solvents and heavy metals with sperm functional impairment and teratozoospermia. The results underscore the importance of routine reproductive health surveillance and oxidative stress monitoring among workers in high-risk occupational settings.",

Evidence suggests increased risks of clubfoot in offspring associated with maternal medication and cigarette smoking exposure in early pregnancy. We explored whether such associations differed by clubfoot laterality. This case-control study was conducted in Massachusetts, North Carolina, and New York (2007-2011). State birth defects registries reported clubfoot diagnoses among infants aged <\u200911\u2009months. Controls without birth defects were random samples of infants from the same catchment areas and born in the same year as cases. Mothers were interviewed within 12 months following delivery. Logistic regression estimated odds ratios (OR) and 95% confidence intervals (CI). Our analysis included 643 isolated cases (bilateral N\u2009=\u2009321, left N\u2009=\u2009180, right N\u2009=\u2009142) and 2037 controls.

In multiple sclerosis (MS), ChP enlargement occurs early in the disease course, yet its normative lifespan trajectory and relationship with MS-specific features remain poorly defined. We aimed to define the normative ChP volume model, to characterize its trajectory across the healthy lifespan, and to assess ChP enlargement in MS using z-scores, evaluating associations with demographic, clinical, MRI, and genetic variables, including human leukocyte antigen (HLA) and non-HLA polygenic risk scores (PRSs). This monocentric retrospective cross-sectional study included 461 healthy controls (HCs) and 727 patients with MS (age 18-70 years) who underwent 3T brain MRI and neurologic assessment. ChP volumes were quantified using ASCHOPLEX, normalized for head size, and modeled in HCs. We derived age-related normalized ChP volume (NChPV) trajectory across adulthood. Z-scores for patients with MS were computed. PRSs were calculated from established MS susceptibility loci, encompassing both HLA and non-HLA regions. In HCs, normalized brain volume, lateral ventricle volume, and its squared term were independently associated with NChPV (R2 = 0.54). Model-derived NChPV trajectory remained stable until age 35 and then increased nonlinearly (p-FDR<0.002), with annualized growth rates rising from 0.24% at age 35 to over 0.7% in later decades. Patients with MS had significantly higher NChPV z-scores than controls (estimated mean [EM] z-score = 0.452, p-FDR<0.001), consistently across phenotypes (p = 0.744) and ages, with no evidence of age-dependent variation (\u03b2 = 0.02 \u00d7 10-2, p = 0.957). In cross-sectional analyses, NChPV z-scores, already elevated 1 year after disease onset (EM z-scores = 0.252, p-FDR<0.001), increased further up to 5 years after disease onset (EM z-scores = 0.463, p-FDR<0.001), before plateauing. Higher z-scores were associated with greater T2-hyperintense white matter lesion volume (\u03b2 = 0.012 \u00d7 10-2, p < 0.001) and HLA genetic burden (standardized \u03b2 = 0.097, p = 0.038), but not non-HLA PRSs (p \u2265 0.177). We provided a normative ChP volume model, characterized its trajectory across the healthy lifespan, and showed early, consistently higher ChP volume in patients with MS across ages and disease durations in cross-sectional analyses, linked to inflammatory lesion burden and HLA-mediated genetic risk. The ChP may represent a noninvasive biomarker of neuroinflammation and HLA-related immunogenetic background in MS.",

In a cuprizone (CPZ)-induced demyelination mouse model, proteomic analysis revealed the significant downregulation of a myelin basic protein-derived peptide (sequence: DTGILDSIGRFFS), which we have designated as NSDP1 (nervous system-derived peptide 1). In vitro, NSDP1 suppressed LPS-induced microglial activation in BV2 cells, reducing reactive oxygen species (ROS) production, downregulating pro-inflammatory markers (iNOS, TNF-\u03b1, IL-1\u03b2), and upregulating the expression of anti-inflammatory marker Arg-1. In vivo, NSDP1 administration via intracerebroventricular injection significantly mitigated CPZ-induced weight loss and demyelination in the corpus callosum. NSDP1 attenuated CPZ-induced demyelination, restoring expression of myelin proteins (MAG, MOG), increasing oligodendrocyte precursor cell (OPC) density, improving myelin sheath ultrastructure, and enhancing axonal myelination efficiency. Furthermore, NSDP1 attenuated CPZ-induced reactive gliosis, reducing both microglial activation and astrocytic reactivity in the corpus callosum. RNA sequencing revealed that NSDP1 modulated myelination-related pathways and correlated with improved locomotor recovery. Mechanistically, NSDP1 exerted its anti-inflammatory effects by inhibiting the cGAS-STING signaling pathway, as shown by reduced cGAS and STING expression in LPS-stimulated BV2 cells. The effects of NSDP1 on ROS and pro-inflammatory cytokine release were reversed by the STING activator DMX and mimicked by the STING inhibitor SN-011. Collectively, these findings identify NSDP1 as a downregulated myelin-derived peptide with potent therapeutic potential, which attenuates demyelination and suppresses neuroinflammation in demyelinating diseases by inhibiting the cGAS-STING pathway.",

Achieving this response is especially challenging with inactivated or subunit vaccines, which lack the ability of live-attenuated formulations to mimic the natural infection process needed to induce strong intestinal mucosal immunity. Specifically, the inactivated polio vaccine (IPV), administered parenterally, elicits strong systemic immunity but fails to induce the mucosal IgA responses required to fully block poliovirus transmission, a critical step toward complete eradication. To address this limitation, we developed a clinically translatable and scalable nanoparticle-based intestinal mucosal adjuvant by encapsulating Am80, a small hydrophobic molecule known to promote intestinal mucosal immunity, within nanoparticles (NPs) designed for lymph node delivery, without requiring antigen modification, encapsulation, or adsorption. Encapsulation in NPs eliminated the need for the use of organic solvents, reduced toxicity, and prevented degradation, while lipid nanoparticles (Am80-LNPs) were engineered for sustained release over 3 to 5 days with high encapsulation efficiency (78\u00a0\u00b1\u00a09%). Cy5-labeled Am80-LNPs localized to draining lymph nodes within 6 hours and were retained for up to 72 hours. Coadministration of Am80-LNPs with the licensed IPV-2 in a Wistar rat model significantly boosted IPV-2-specific fecal IgA by 20-fold compared to IPV-2 alone and threefold over free Am80. These findings demonstrate that Am80-LNPs significantly enhance IPV-2-specific mucosal immunity in vivo and suggest their potential as a potent mucosal adjuvant against other enteric pathogens.",

Multiple sclerosis is a chronic autoimmune condition affecting the central nervous system, marked by inflammation and damage to nerves and the myelin sheath. A case-control study conducted from September 2022 to January 2024 included 832 participants-263 diagnosed with MS and 569 controls. Controls were matched by age, gender, residence, and employment status. Data was collected using a validated questionnaire, with written consent obtained from participants aged 18 and older. Logistic regression analysis was used to ascertain risk factors. Out of 832 participants, 263 (31.6%) were diagnosed with MS. The greatest percentage of MS cases occurred in the 25-34 age range (37.7%). After adjusting for potential confounders, smoking was significantly associated with increased MS risk (AOR = 2.34, 95% CI: [1.22-4.48], p = 0.01), as were vitamin D deficiency (AOR = 1.97, 95% CI: [1.31-2.98], p<0.00), and a history of childhood sexual abuse (AOR = 1.96, 95% CI: [1.11-3.45], p = 0.02). Conversely, vitamin D supplementation was associated with a substantial reduction in MS risk (AOR = 0.17, 95% CI: [0.10-0.28], p < 0.001), as was coffee consumption (AOR = 0.53, 95% CI: [0.30-0.96], p < 0.04). Smoking, vitamin D deficiency, and a history of childhood sexual abuse increase MS risk, while vitamin D supplementation and coffee consumption reduce it. Further research is essential to confirm these findings.",

Helminth-derived excretory-secretory products (ESP) are immunomodulatory molecules that suppress host inflammation and are promising candidates for MS treatment. However, their capacity to promote remyelination remains poorly understood. This study investigated the effects of Fasciola hepatica ESP in the cuprizone-induced demyelination model. Male C57BL/6 mice were divided into four groups: control (CON), control\u2009+\u2009FES (CON\u2009+\u2009FES), cuprizone (CUP), and cuprizone\u2009+\u2009FES (CUP\u2009+\u2009FES). FES was administered intraperitoneally during the demyelination phase. Motor and cognitive functions were evaluated using open field, rotarod, wire grip, and shuttle box tests. Neuroinflammation was assessed by measuring TNF and IL-1\u03b2 levels, while myelin-related changes were evaluated by MBP and Olig2 expression (ELISA and qPCR) and Luxol Fast Blue staining. FES treatment significantly reduced pro-inflammatory cytokines, increased MBP and Olig2 levels, improved myelin integrity, and enhanced motor and cognitive performance compared to untreated cuprizone mice, though full recovery to control levels was not achieved. These findings demonstrate that FES attenuates neuroinflammation and is associated with partial improvements in myelin-related outcomes in the cuprizone model, supporting the therapeutic potential of helminth-derived molecules for MS.",

We examined whether prenatal Cd exposure was associated with behavioural and emotional symptoms from early childhood to pre-adolescence in the Spanish INMA birth cohort. We included 1270 mother-child pairs from Valencia, Sabadell, and Gipuzkoa. Cd and creatinine were measured in maternal urine collected in the first and third trimesters of pregnancy, and average prenatal Cd exposure was analysed. Behavioural and emotional outcomes were assessed at ages 4-5, 7-8, 9, and 11 years using the ADHD-DSM-IV, Strengths and Difficulties Questionnaire, and Conners' Parent Rating Scales-Revised. Associations were estimated using multivariable negative binomial and mixed-effects models, with additional analyses for trimester-specific exposure, non-linearity, and effect modification by selected single nucleotide polymorphisms. Prenatal Cd exposure was not associated with any behavioural or emotional outcome across childhood. Results were also null when exposure was analysed separately for the first and third trimesters. In contrast, male sex and maternal smoking during pregnancy were consistently associated with poorer behavioural scores, whereas higher parental education and parity were generally associated with lower symptom levels. Interaction analyses indicated greater susceptibility among children whose mothers carried the MT1DP rs8044719 GT\u00a0+\u00a0TT genotype. In this population-based cohort, prenatal Cd exposure was not associated with behavioural or emotional problems across childhood. The findings nevertheless suggest that genetic susceptibility may contribute to interindividual differences in Cd-related neurodevelopmental vulnerability.",

This study investigates the association between air pollution and incident AS, integrating gene-environment interactions and network toxicology. Based on the UK Biobank as the primary cohort, long-term air pollution exposure\u00a0(per standard deviation\u00a0increase) is associated with an increased risk of\u00a0AS, with HRs and 95% CIs of 1.60 (1.55,1.66) for PM2.5, 1.37 (1.32, 1.41) for PM10, 1.37 (1.32, 1.42) for NO2, and 1.36 (1.31, 1.41) for NOx. The observed associations demonstrate high consistency across a suite of advanced internal methodological validations and are further replicated in the Tianshan Community Cohort. There are joint and interactive effects of genetic susceptibility and air pollutants on AS risk. Network toxicology and bioinformatics analyses reveal key PM-AS target genes enriched in the lipid and atherosclerosis, fluid shear stress and atherosclerosis, and IL-17 signaling pathway. In conclusion, long-term exposure to PM2.5, PM10, NO2, and NOx is significantly associated with an increased AS risk, with a potential interaction between environmental exposure and genetic susceptibility.",

In this post hoc analysis, the effects of siponimod versus placebo on time to sustained Expanded Disability Status Scale (EDSS) \u2265\u20097.0 over the core part of the Phase 3 EXPAND study were assessed. The time to sustained EDSS \u2265\u20097.0 (time to requiring a wheelchair) was analysed for participants with secondary progressive multiple sclerosis (SPMS). Analyses were based on a While on Treatment (WOT) set that censored participants if entering open-label treatment. Subgroup analyses were conducted in participants with active versus non-active SPMS (defined based on pre-study/baseline criteria), and in participants with baseline EDSS 6.5. In the overall EXPAND population, siponimod reduced the risk of reaching sustained EDSS \u2265\u20097.0 (requiring a wheelchair) by 40% (hazard ratio [HR], 0.60; 95% confidence interval [CI], 0.41-0.88; p\u2009=\u20090.009) versus placebo; the reduction in risk was 51% (HR, 0.49; 95% CI, 0.29-0.81; p\u2009=\u20090.005) versus placebo in participants with active SPMS and 22% (HR, 0.78; 95% CI, 0.42-1.45; p\u2009=\u20090.437) in non-active SPMS. Siponimod reduced the risk of requiring a wheelchair in participants with SPMS versus participants receiving placebo, with a greater effect in those with active disease. Time to requiring a wheelchair is a highly relevant treatment goal and an important indicator of treatment effect in patients with SPMS.",

Shared risk factors and mechanisms, including insulin resistance, adiposity, and chronic inflammation, underpin its development. Growing evidence also implicates that even low-level, long-term exposure to fine particulate matter, nitrogen dioxide, and related pollutants can accelerate the trajectory of cardiometabolic MLTC. Early-life exposures, including undernutrition and overnutrition, altered gut microbiome, and endocrine-disrupting chemicals, interact with social determinants of health to aggravate inflammatory and metabolic dysregulation. These mechanisms, together with genetic susceptibility, epigenetic modifications, and multiomics perturbations, shape disease progression, heterogeneity, and the clustering of cardiometabolic MLTC. Yet, fundamental gaps persist, whereby most mechanistic insights are derived from single-disease studies, leaving the temporal hierarchy, causal pathways, and population-level heterogeneity largely unresolved. Addressing these challenges will require life-course research, integrative systems approaches, and translational studies that link mechanistic insights to precision prevention and therapeutic strategies. By bridging discovery with actions, such efforts can enhance care for cardiometabolic MLTC and promote equitable health outcomes globally.",

We aimed to investigate the association between hypertension and tinnitus in detail using a large, population-based dataset from a rural setting.DesignObservational cross-sectional study.SettingSheshdeh, Fasa, Iran. We analysed data from 9775 individuals in the general population, aged 35-70 years, excluding those with a history of cancer, pregnancy or medical conditions known to cause tinnitus, such as stroke, seizures or multiple sclerosis. Additionally, although the study design aimed to exclude participants using aminoglycosides because of their significant ototoxic effects, no such users were identified during the study period. Hypertension was defined as a systolic blood pressure (SBP) of \u2265140\u2009mm Hg or a diastolic blood pressure (DBP) of \u226590\u2009mm Hg on at least two separate measurements or as current use of antihypertensive medications following a prior diagnosis. These medications included ACE inhibitors, angiotensin receptor blockers, diuretics, aldosterone antagonists and atenolol. Stage I hypertension was classified as an SBP of 140-159\u2009mm Hg or a DBP of 90-99\u2009mm Hg, while stage II was defined as an SBP of \u2265160\u2009mm Hg or a DBP of \u2265100\u2009mm Hg. Controlled blood pressure was defined as values below these thresholds. Tinnitus, assessed by a self-reported questionnaire, was defined as a continuous wheezing sound in the ear persisting for more than 1\u2009week. Among participants (4446 males, 5309 females; mean age 48.55 (SD 9.53) years), the prevalence of tinnitus and hypertension was 7.4% and 19.3%, respectively. Hypertension was significantly associated with higher odds of tinnitus (adjusted OR=1.34; 95%\u2009CI 1.10 to 1.62). Notably, even participants with controlled hypertension had a 27% increased odds (OR=1.27; 95%\u2009CI 1.02 to 1.59) compared with normotensive individuals. The odds were highest in those with uncontrolled grade II hypertension (OR=2.08; 95%\u2009CI 1.25 to 3.47), demonstrating a dose-response relationship. Our findings suggest a positive association between hypertension and tinnitus, with odds increasing alongside the severity and poor control of hypertension. Importantly, even controlled hypertension was associated with elevated odds, indicating that tinnitus screening may be warranted in all hypertensive patients, regardless of control status. These results underscore the need for heightened clinical awareness and further research into the pathophysiological mechanisms linking vascular health and auditory symptoms.",

As populations age worldwide, the epidemiological burden of AD is expected to more than double by 2050, surpassing 150\u00a0million affected individuals. While genetic susceptibility, particularly the apolipoprotein E \u03b54 (APOE4) allele, modulates individual risk, most AD cases are late-onset and shaped by complex interactions between genetic background and modifiable environmental exposures. Environmental pollution has emerged as a critical and potentially preventable contributor to this burden. The 2024 Lancet Commission on Dementia Prevention, Intervention, and Care has identified 14 modifiable risk factors, with air pollution explicitly included. Drawing on evidence from human epidemiological cohorts, experimental animal models, and in vitro neuronal/glial systems, the present review aims to synthesize mechanistic evidence linking environmental pollutant classes to AD-relevant neuropathology. The review examines the growing body of evidence linking major categories of environmental pollutants (ambient particulate matter, heavy metals, pesticides, PFAS, and emerging contaminants including microplastics and nanoplastics) to AD risk and pathogenesis. Special attention is given to studies showing that the characteristic neuropathological features of AD may emerge in children and young adults chronically exposed to heavily polluted urban environments, which highlights critical concerns about when and how these changes develop throughout life. Shared mechanistic pathways through which environmental pollutants promote neurodegeneration are discussed, including neuroinflammation, oxidative stress, blood-brain barrier disruption, tau kinase dysregulation, epigenetic reprogramming, and gut-brain axis dysbiosis. The review also examines the amplifying role of biological aging on neurotoxic vulnerability and proposes a comprehensive, multi-level prevention framework addressing individual exposure reduction, clinical risk identification, and population-level policy interventions.",

With various genetic and environmental risk factors, the accumulation of harmful amyloid plaques containing amyloid-\u03b2 (A\u03b2) peptides is one of the main hallmarks of AD. Recent findings show that the innate immune protein interferon-induced transmembrane protein 3 (IFITM3) binds to \u03b3-secretase and modulates A\u03b2 production, providing a direct link between neuroinflammation, amyloidogenesis, and the pathogenesis of AD. In this review, we explore IFITM3-mediated modulation of \u03b3-secretase complex activity and its pivotal role in AD pathology during neuroinflammation. Furthermore, we also provide an overview of the recent growing evidence connecting the roles of infection, the immune system, and AD pathogenesis.",

Epidemiological data further support a bidirectional association between the two conditions, suggesting the presence of shared autoimmune pathways. These converging features provide a rationale for exploring shared therapeutic strategies based on targeted immune modulation. Monoclonal antibodies (mAbs) have emerged as powerful tools for targeted immune modulation. In MS several mAbs, particularly B-celldepleting anti-CD20 therapies, have transformed disease management. In contrast, the therapeutic impact of immunotherapy in T1D has historically been limited by rapid and largely irreversible \u03b2-cell loss, a narrow therapeutic window, and marked disease heterogeneity. The recent approval of the anti-CD3 antibody teplizumab for delaying the onset of clinical T1D represents an important milestone in this field. This review examines shared and divergent immunological mechanisms underlying MS and T1D and evaluates monoclonal antibody therapies targeting CD3, CD20, and CD40L across both diseases. By comparing their mechanisms of action and therapeutic outcomes, we highlight how differences in molecular pathogenesis, tissue context and therapeutic window influence the effect of immunetargeted therapies. We also discuss the opportunities and limitations of cross-disease immunomodulation and emerging strategies including combination and dual-indication therapies.",

However, data on viral shedding following intracranial infection are sparse for some strains and entirely absent for others, such as the Daniels strain, making it difficult to accurately assess the biological risks associated with infected animals. In our study, we used a combination of RT-qPCR and immunoassays to evaluate viral shedding and the associated infectious risk. We show that viral RNA is detectable in the feces of some mice and that the proportion of shedding animals varies by mouse line. Nevertheless, none of the sentinel mice exposed to soiled bedding from infected animals exhibited seroconversion, indicating that the viral particles are either present at levels below the minimum infectious dose or represent residual, non-infectious material rather than active, transmission-competent virus.",

Their morphological alterations are commonly assessed by qualitative histopathology, yet quantitative tools are required to better capture astrocytic heterogeneity and to allow correlations with imaging-derived biomarkers. Here, we present a workflow for the quantitative analysis of Glial Fibrillary Acidic Protein (GFAP) network remodeling in astrocytes in the cuprizone model of demyelination. C57BL/6 mice were intoxicated with cuprizone for 3 or 5 weeks to induce progressive demyelination, microglial activation, and reactive astrogliosis. Brain sections were processed for anti-GFAP immunohistochemistry, and individual astrocytes from the stratum oriens of the hippocampus were digitally reconstructed. Diverse parameters of GFAP topology, including soma size, process length, branching order, convex hull area, and ramification index, were extracted using either the commercial Neurolucida\u00ae 360 software or the open-source Simple Neurite Tracer (SNT) plugin in ImageJ. Principal component analysis revealed clear differences between control astrocytes and astrocytes in cuprizone-intoxicated animals, with reactive astrocytes displaying increased numbers of primary processes, enhanced bifurcation, and process complexity. Comparative evaluation of Neurolucida\u00ae 360 and SNT demonstrated that both tools are suitable for astrocyte reconstruction, although Neurolucida\u00ae 360 enabled faster and more detailed tracing.

We aimed to study the association between green/blue space and incident IBS, and to assess effect modification by genetic susceptibility. The study included 376\u2009749 UK Biobank participants at baseline. Residential green space was measured using the normalised difference vegetation index (NDVI), and blue space was defined by distance to the nearest water bodies. For time-to-event analyses, we used Cox proportional hazards models, polygenic risk scores (PRS), and mediation analysis to test gene-environment interactions. Results are presented as hazard ratios (HRs) with 95% confidence intervals (95% CIs). During a follow-up of 11.73 years, 7091 incident IBS cases were documented. Higher residential green space exposure was associated with reduced risk of incident IBS. Specifically, within a 1000 m buffer, each interquartile range (IQR) increase in NDVI corresponded to a 5% lower IBS risk (HR\u2009=\u20090.95; 95% CI\u2009=\u20090.91-0.98), with consistent effects observed at 800 m and 500 m buffers. Conversely, a greater distance to water bodies was associated with reduced IBS risk. Stratification by PRS revealed a significant interaction: increased green space (1000 m buffer) reduced IBS risk by 8% exclusively among high-genetic-risk individuals (HR\u2009=\u20090.92; 95% CI\u2009=\u20090.88-0.96), whereas no interaction was observed for blue space. Moreover, physical activity mediated the association between green space and IBS. Increased residential green space exposure is associated with reduced IBS incidence, particularly among individuals with high genetic susceptibility. These findings underscore the importance of urban greening as a public health strategy to mitigate IBS risk, highlighting the potential for targeted environmental interventions to offset genetic predispositions.",

Herein, we report a simple and efficient nucleic acid extraction platform based on a chitosan-derived sponge-like cryogel (CSC), enabling dynamic adsorption-elution-driven separation under mild conditions. The CSC exhibits high nucleic acid binding capacity (88\u202f\u03bcg for DNA and 305\u202f\u03bcg for RNA per 10\u202fmg material) and rapid adsorption kinetics following a pseudo-second-order model. Isotherm analyses indicate that RNA and DNA binding follow the Langmuir and Freundlich models, respectively, suggesting a combined mechanism of electrostatic interaction and physical entanglement. Notably, the compressible and shape-recoverable structure enables dynamic extraction through simple aspiration-compression operations, eliminating the need for external equipment. For practical application, the CSC was integrated into a Pasteur pipette to construct a portable extraction device. This system allows rapid nucleic acid purification from Vibrio parahaemolyticus and Salmonella in bacterial cultures and milk samples, with direct compatibility for quantitative polymerase chain reaction (qPCR) and recombinase polymerase amplification (RPA)-clustered regularly interspaced short palindromic repeats (CRISPR)/Cas12a assay. The method achieved sensitive detection down to 103\u202fCFU\u202f\u00b7mL-1, outperforming a commercial kit.

Although genetic predisposition contributes to asthma susceptibility, the high burden of disease-particularly in high-sociodemographic-index regions-points to a central role of environmental exposures characteristic of the modern environment. This review synthesizes current evidence linking ambient air pollution and heavy metal exposure to childhood asthma, with a focus on early-life vulnerability, underlying biological mechanisms, and implications for prevention. We reviewed epidemiological, toxicological, and mechanistic studies published through November 2025, prioritizing systematic reviews and meta-analyses while integrating recent cohort studies, intervention trials, and experimental research. Epidemiological findings consistently demonstrate that prenatal and early-childhood exposure to particulate matter (PM\u2082.\u2085, PM\u2081\u2080), traffic-related air pollutants (e.g., NO\u2082, black carbon), and ozone is associated with increased asthma incidence, wheezing, reduced lung function, and higher rates of exacerbations and healthcare utilization. In contrast, evidence for metal-related exposures is more heterogeneous. Toxic metals and metalloids, transition metals in particulate matter, and essential trace-element status may contribute to asthma risk through biologically plausible pathways, but associations appear to depend on exposure timing, exposure source, biomarker type, co-exposures, and population context. Mechanistic studies reveal shared and interacting pathways involving oxidative stress, airway epithelial barrier disruption, immune dysregulation, epigenetic modifications, and microbiome alterations. The effects of these exposures are magnified during critical developmental windows and modified by genetic susceptibility and social determinants of health, contributing to marked environmental health inequities. Overall, childhood asthma is strongly shaped by early-life exposure to air pollution and heavy metals through interconnected biological and social pathways. Addressing these preventable environmental risks is essential for effective asthma prevention and for reducing global disparities.",

We examined the combined effect of all the predictive elements associated with poor outcomes at year 3, in relation with the choice of first-line disease-modifying therapies or high-efficacy DMT (fl-DMT or he-DMT). To analyze the influence of poor prognosis risk factors on clinical outcomes.

Emerging evidence indicates the existence of a lung-brain axis, through which pulmonary pathology and environmental exposures can influence neurological health. The current review highlights the mechanistic and clinical evidence linking chronic lung inflammation, air pollution, and immune dysregulation to the onset and progression of Alzheimer's disease (AD), Parkinson's disease (PD), Multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS). A pathway-based framework is presented in which lung inflammation, systemic cytokine release, oxidative stress, blood-brain barrier disruption, immune priming, and protein misfolding mediate lung-to-brain communication. Associations between chronic obstructive pulmonary disease, asthma, particulate matter exposure, and adverse neurological outcomes including cognitive decline, brain atrophy, disease progression, and elevated neurodegenerative risk are emphasized. Specific mechanisms are addressed, including immune-mediated effects in multiple sclerosis, inhalation-driven protein aggregation in Parkinson's disease, and vascular and oxidative injury contributing to dementia and amyotrophic lateral sclerosis. COVID-19 is considered a clinical model of acute lung-brain axis disruption, demonstrating inflammation-driven neurocognitive consequences, and its role in this context was also highlighted. Additionally, potential preventive and therapeutic strategies are discussed, highlighting pulmonary health and environmental exposure reduction as modifiable factors that may help mitigate neurological disease. This integrative review underscores the clinical relevance of the lung-brain axis and calls for interdisciplinary strategies to improve neurological outcomes through pulmonary and environmental interventions.",

In the present study, a sustainable synthetic approach was developed for the preparation of novel benzothiazole and benzimidazole derivatives via the condensation of carbohydrate-derived furaldehydes with 2-aminobenzenethiol and o-phenylenediamine, respectively. Various biogenic carboxylic acids were evaluated as catalysts, among which nicotinic acid exhibited superior catalytic efficiency, reusability, and compatibility with both aqueous and green organic solvents under conventional heating, affording the targeted products in excellent isolated yields (74-95%). The antimicrobial potential of the synthesized compounds was assessed using agar well diffusion and cup-plate methods against selected bacterial and fungal strains, revealing that several derivatives displayed significant inhibitory activity comparable to that of standard drugs. Two representative benzothiazole derivatives (4d and 4g) were further investigated by single-crystal X-ray diffraction to elucidate their molecular and supramolecular architectures. Density functional theory calculations based on experimentally determined geometries showed good electronic stability and comparable reactivity, while Hirshfeld surface analysis highlighted that the molecules in the crystal interact by hydrogen-bonding and \u03c0\u22ef\u03c0 interactions. Moreover, in silico ADMET studies indicated favorable drug-like properties and pharmacokinetic profiles, such as favorable oral absorption and moderate blood-brain barrier permeability.",

Given the growing appreciation that short glycans are biologically and clinically important, we here address this analytical shortcoming by testing the glycoprofiling performance of a new Supel Carbon PGC phase. Employing a shallow gradient of organic solvent, we systematically explored the separation potential of two micro-bore column geometries (15\u202fcm\u202f\u00d7\u202f0.3 mm and 15 cm x 1\u202fmm) using mixtures of isobaric monosaccharides (GlcNAc, GalNAc), disaccharides (lactose, maltose) and complex N- and O-glycans from pig gastric mucin, bovine submaxillary mucin, THP-1\u202fcells, bovine fetuin and recombinant human IgM. Matching an existing PGC phase (HyperCarb), the Supel Carbon columns consistently retained isobaric mono- and disaccharides, but afforded improved baseline separation enabling confident saccharide quantitation. The Supel Carbon PGC columns also efficiently separated short O- and N-glycans released from biological sources including disease-relevant Tn, T and sialyl Tn while maintaining effective separation of elongated and branched glycans including near-identical structural isomers. Reproducible glycan detections were achieved within and across column manufacturing lots and low femtomolar detection limits were observed for the micro-bore columns. Finally, the impacts of alternative organic solvents (methanol, ethanol) and flow rates on column performance were also established. Our findings position the Supel Carbon PGC phase as a valuable tool in the glycomics toolbox enabling reproducible profiling of truncated and elongated glycan isomers.",

Although oligodendrocyte progenitor cells (OPCs) persist in demyelinated lesions, they often fail to differentiate into myelinating oligodendrocytes. This study aimed to determine whether growth differentiation factor 11 (GDF11), a circulating member of the TGF-\u03b2 superfamily, regulates oligodendrocyte differentiation, CNS myelination, and remyelination. The effects of GDF11 were examined using purified mouse OPC cultures, a neonatal developmental myelination model, and two demyelination models: cuprizone-induced demyelination and experimental autoimmune encephalomyelitis (EAE). OPC differentiation was assessed by immunocytochemistry and morphological analysis. In\u00a0vivo myelination and remyelination were evaluated using histological, ultrastructural, and behavioral approaches following systemic GDF11 administration. GDF11 directly promoted OPC differentiation and maturation in\u00a0vitro without affecting proliferation. Systemic GDF11 enhanced developmental myelination in neonatal mice, increasing myelin gene expression, myelinated axon density, and myelin thickness. Although GDF11 did not prevent active demyelination, it significantly accelerated remyelination and functional recovery following cuprizone withdrawal and in the EAE model, and this was accompanied by enhanced oligodendrocyte differentiation and reduced neuroinflammation. These findings identify GDF11 as a circulating regulator of oligodendrocyte maturation and CNS myelin formation and repair, highlighting its therapeutic potential for demyelinating diseases.",

Codon-optimized TaqMn-SOD fused with a C-terminal 6His tag was expressed in Escherichia coli. The apoenzyme (ApoTaqMn-SOD) was successfully recovered and purified under optimized induction conditions followed by post-lysis thermal treatment (85\u202f\u00b0C for 90\u202fmin), affording a yield of >100\u202fmg of purified protein per liter of culture. The purified TaqMn-SOD exhibits a specific activity of about 3000 U/mg and exceptional stability profiles: retaining full activity at 85\u202f\u00b0C for 4\u202fh; maintaining >56% activity across a broad pH range of 3.0-12.0; tolerating ethanol concentrations up to 40%, preserving >80% activity after 48\u202fh and 50-80% activity after 90\u202fd in 5-20% ethanol. Moreover, its activity was not significantly affected by various divalent metal ions (excepting Fe2+), organic solvents, detergents, denaturants, or the chelating agent EDTA, with n-hexane enhancing activity by 47%. The enzyme was partially inactivated (47%) in simulated gastric fluid for 10\u202fmin, but remained stable in simulated intestinal fluid and water. These results suggest that TaqMn-SOD holds potential for applications in high-temperature food processing, thermally-stable cosmetic manufacturing, agricultural protection, and pharmaceutical formulations requiring stability under extreme conditions.",
        "42331740": "ID: 42331740\nTitle: Pharmacokinetic Studies of Amyloid-Targeting Bis(styryl)benzene Agents for Alzheimer's Disease.\nAbstract: The pharmacokinetics (PK) and biodistribution of radiolabeled amyloid-\u03b2 (A\u03b2)-targeting probes have been extensively characterized in the context of Alzheimer's disease (AD), whereas the corresponding nonradiolabeled scaffolds remain largely unexplored in vivo. Herein, we report in vivo PK studies of the widely used amyloid probe methoxy-X04 (MeX04) in transgenic 5xFAD and wild-type (WT) mice. In plasma, MeX04 shows comparable exposure between 5xFAD and WT mice, indicating no major genotype-dependent differences in systemic clearance. In contrast, brain exposure was markedly increased in 5xFAD mice, with higher brain Cmax and AUC parameters and slower washout, consistent with A\u03b2-dependent sequestration and retention in the AD brain tissue. Notably, fluorescence microscopy revealed that the fluorescence intensity of amyloid plaque-bound MeX04 closely mirrored the total brain concentration, and we employed ex vivo fluorescence intensity quantification to evaluate the PK of a related bis(styryl)benzene compound, LS-4, which is proposed to exhibit increased affinity for soluble A\u03b2 aggregates. We then performed age-dependent ex vivo staining of compound-bound A\u03b2 aggregates in 5xFAD brains, and LS-4 exhibits appreciable amyloid-bound fluorescence intensity in younger 5xFAD mice, consistent with its higher affinity for A\u03b2 oligomers, whereas MeX04 exhibited stronger fluorescence intensity in older mice. Consequently, we propose an efficient approach to track temporal changes in the PK of A\u03b2-binding compounds by ex vivo evaluation of their amyloid-bound fluorescence intensity, providing a rapid assessment of the general PK trends of newly developed amyloid-binding probes.",
        "42334224": "ID: 42334224\nTitle: Mapping the Parkinson's pandemic: Unveiling and addressing the global burden.\nAbstract: Worldwide, the incidence, prevalence, disability, and mortality associated with Parkinson's disease (PD) have increased substantially, placing an immense strain on healthcare systems across countries of all income levels, prompting the use of the term \"Parkinson pandemic\" to emphasize the urgent need for coordinated strategies to address its worldwide impact. This narrative review explores the regional differences in the dramatic increase in PD burden, along with its genetic, environmental, and socioeconomic determinants worldwide. Furthermore, it discusses the healthcare access in different regions and proposes strategies to combat this pandemic. The rising burden of PD is largely driven by population aging, increased life expectancy, and potentially by greater exposure to by-products of industrialization-such as pesticides, air pollution and heavy metals- and declining smoking rates, which vary across world regions. Differences in prevalence, demographic, genetic and lifestyle factors, the impact of urbanization and environmental risk factors, as well as inequality and disparities in access to care and healthcare services, have been outlined, mandating the development of tailored and region-specific strategies to mitigate the pandemic and reduce its burden globally and regionally. These strategies include exploring relevant genetic and environmental determinants, promoting research, increasing public awareness, facilitating early diagnosis and optimal management, improving access to healthcare services, supporting caregivers, encouraging the adoption of protective lifestyle factors, ensuring the availability of essential medications and controlling environmental exposures such as toxicants. Global Burden of Parkinson's Disease worldwidePlain language summaryMapping the global burden of Parkinson's diseaseThe global burden of PD is increasing over the past decades worldwide, with estimated that about 12 million had PD in 2021 and might exceed 25 million by 2025. This global rise places an immense strain on healthcare systems across all countries, prompting the use of the term Parkinson Pandemic to emphasize the urgent need for coordinated strategies to address its worldwide impact. However, considerable regional variability in its burden exists, attributed to differences in prevalence, underlying genetic and environmental risk factors and its interaction, variable population aging and growth, life expectancy, lifestyle factors, awareness and early diagnosis as well as inequality and disparities in access to care and healthcare services. This review recognizes the determinants of PD pandemic and their variations across continents and discusses proposed strategies to combat this growing global challenge.Regional differences of PD prevalence are well recognized. High-income countries reported high prevalence, while low-middle-income countries showed a greater increase over recent decades. Understanding genetic variations among populations might explain the variability of PD prevalence, explore disease pathogenesis and tailor future therapies. Additionally, environmental risk factors for PD show marked global variation, reflecting differences in industrialization, agricultural practices and regulatory frameworks, with higher risk in areas with intensive agriculture, industrial emissions, and heavy air pollution.Comprehensive strategies to combat this pandemic include exploring relevant genetic and environmental determinants, promoting research, increasing public awareness, facilitating early diagnosis and optimal management, improving access to healthcare services, supporting caregivers, encouraging the adoption of protective lifestyle factors, ensuring the availability of essential medications and controlling environmental exposures such as toxicants.",
        "42336260": "ID: 42336260\nTitle: Acute or repeated exposure of aerosolized flame retardants induces molecular and structural alterations in lung slices.\nAbstract: Organophosphate flame retardants (OPFRs) such as tributyl phosphate (TBP) are widely used industrial additives increasingly detected in the environment and human tissues, yet their inhalation toxicity remains poorly characterized. In this study, we employed the ex vivo porcine precision-cut lung slice (pPCLS) model to investigate the cytotoxic, oxidative stress, and structural effects of aerosolized TBP under both acute and repeated exposure conditions. Using the Vitrocell\u00ae, pPCLS were exposed to TBP aerosols at deposited surface concentrations (\u00b5g/cm\u00b2) within ranges commonly applied in ALI-based inhalation toxicology models and selected to simulate cumulative low-dose exposure scenarios reported for organophosphate flame retardants in indoor environments. Acute exposure (24\u202fh) caused a reduction in tissue viability, increased reactive oxygen species (ROS) production, and enhanced caspase-3 activation, indicating mitochondrial stress and apoptosis induction. There is a potential tendency for markers (K-RAS, p53, and MMP-15) to increase. Histological analyses revealed disruption of extracellular matrix architecture. Repeated low-dose exposure (5\u202f\u00d7 24\u202fh) led to progressive tissue disorganization and early signs of fibrogenic remodeling, evidenced by increased collagen deposition, p53 expression, reduced tissue viability, and sustained oxidative stress. These findings suggest that cumulative subcytotoxic exposure to aerosolized TBP can initiate pathways associated with chronic pulmonary injury. The pPCLS model demonstrated high reproducibility, preserved lung architecture, and responsiveness to chemical insult, reinforcing its translational relevance for respiratory toxicology. Overall, our results provide mechanistic insight into TBP-induced lung toxicity and highlight precision-cut lung slices as a useful model for evaluating inhalation hazards of industrial chemicals.",

Due to limitations in the efficacy and side effects of the currently available treatments of MS this study is designed to explore neuroprotective role of artocarpin enriched extract (AEE) of Artocarpus heterophyllus heartwood as a favorable natural therapeutic substitute in MS. AEE was prepared from the heartwood of A. heterophyllus using a green microwave-assisted extraction technique. To assess the safety profile of AEE acute toxicity assessment was performed in accordance with OECD guidelines. Molecular docking analysis was performed to analyze the binding affinity and interaction behavior of artocarpin against multiple therapeutic targets S1PR1, MMP-9, BTK, IL-17, TNF-\u03b1 and NLRP3. For the therapeutic evaluation of AEE, in cuprizone (CPZ) induced demyelination, forty-two Wistar albino rats were selected and evenly distributed into seven groups: Normal control (NC), disease control (DC), standard treatment drug (fingolimod, 15\u00a0mg/kg, pure artocarpin (AC) 100\u00a0mg/kg and three treatment groups receiving AEE at dose of 200\u00a0mg, 400\u00a0mg, and 800\u00a0mg/kg. Neuroinflammation was induced in all groups except NC by administering 0.2% w/w 450\u00a0mg/kg cuprizone for 42 days. Behavioral assessments, biochemical analyses, histopathological examinations, gene expression and neurotransmitter level were observed to explore the meyelin protection effects of AEE. Results demonstrated that pure artocarpin and AEE produced significant effects in the protection of neuron myelin sheath and can be considered as a suitable therapeutic agent for further study in MS.",

It is particularly significant in the pharmaceutical field as a key structural unit in many drugs, such as afatinib (an anticancer drug), teriflunomide (used for multiple sclerosis treatment), acebutolol (used for hypertension and arrhythmia treatment), and paracetamol (an antipyretic and analgesic agent). However, chemical synthesis methods usually require harsh reaction conditions (e.g., high temperature, high pressure, or strongly acidic or alkaline environments) and are often accompanied by high energy consumption and environmental pollution issues. In contrast, enzymatic synthesis of amides has attracted widespread attention due to its mild conditions and environmental friendliness. To mine ancestral lipases with high activity and stability and investigate their enzymatic properties, thus achieving efficient enzymatic synthesis of amide bond-containing compounds. Ancestral lipases were screened based on a gene mining strategy employing ancestral sequence reconstruction (ASR), followed by characterization of their enzymatic properties and construction of an enzymatic reaction system for synthesis of the amide bond. Ancestral enzymes ASR-1 and ASR-7 with higher thermal stability were obtained. Substrate spectrum characterization revealed that ASR-1 preferentially catalyzed the synthesis of aromatic amides, while ASR-6 favored the synthesis of aliphatic amides. ASR-1 was purified via nickel-affinity chromatography and characterized for its enzymatic properties, showing an optimal reaction pH in Tris-HCl 7.5 and an optimal reaction temperature of 40 \u00b0C. The reaction conditions for amide synthesis were systematically optimized as 10 mg/mL wet cells, water content \u226410% (V/V), n-dodecane as solvent, 20 mmol/L amine substrate, and 10 mmol/L acyl donor.

Traditionally, the pathogenesis of MAFLD has mainly been attributed to genetic susceptibility and unhealthy lifestyles (such as high-calorie diets and sedentary behavior). However, in recent years, environmental factors, especially air pollution, have been confirmed as independent risk factors and important promoting factors for MAFLD development and further disease progression. This review summarizes current epidemiological findings on the link between air pollution exposure and MAFLD, while exploring its potential biological mechanisms involving systemic inflammation, oxidative stress, immune alteration, genetic risk, and epigenetic regulation underlying the relationship between air pollution and hepatic steatosis. It also reviews the additive interaction between air pollution and lifestyle or socioeconomic factors in MAFLD. Finally, we also discuss multilevel strategies spanning individual-, community-, national-, and global-level cooperation to address the increasing public health burden caused by air pollution. Therefore, incorporating the assessment and control of air pollution into the comprehensive strategies for MAFLD prevention and treatment has important scientific value and public health significance.",
        "42356263": "ID: 42356263\nTitle: The Effect of Polyphenol Supplementation in People with Multiple Sclerosis: A Systematic Review of Clinical Trials.\nAbstract: Background/Objectives: Multiple sclerosis (MS) is an autoimmune neuroinflammatory disease affecting 2.9 million worldwide. Current immunosuppressive treatments offer limited neuroprotection and often cause adverse effects. Polyphenols with antioxidant and anti-inflammatory properties have been investigated as adjuncts in MS. Methods: On 19 June 2025, Embase, Medline, and ClinicalTrials.gov were systematically searched. Eligible clinical trials assessing polyphenol supplementation in MS were included. Outcomes of interest were Expanded Disability Status Scale (EDSS), annualised relapse rate (ARR), magnetic resonance imaging (MRI) changes, safety, and tolerability. Risk of bias was evaluated using the Cochrane tool, and certainty of evidence was appraised with Grading of Recommendations Assessment, Development, and Evaluation (GRADE). The protocol was registered with PROSPERO (CRD420251052042). Results: Of 870 records identified, 13 trials (n = 785) met inclusion. Nanocurcumin consistently improved EDSS in relapsing-remitting MS (3 trials, n = 150; p = 0.039-0.041), while epigallocatechin-3-gallate, silymarin (SM), cranberry extract, and bio-enhanced curcumin extract (BCM-95) curcumin showed no significant impact on disability, relapse rates, or MRI outcomes. Intervention adverse events were generally mild. SM showed potential hepatoprotective effects. Risk of bias was determined as low risk for seven of the trials and of some concern for five of the studies. Most often raising concerns because of selective reporting. Certainty of evidence, assessed using GRADE, was generally moderate, indicating some uncertainty regarding the outcomes. Meta-analysis was not possible due to the heterogeneity of included studies. Conclusions: Nanocurcumin may contribute to improvements in disability outcomes in Relapse Remitting Multiple Sclerosis (RRMS), whereas other polyphenols lack consistent efficacy. However, the evidence base remains limited by small sample sizes and methodological concerns. Larger, multicentre randomised controlled trials are required to establish optimal dosing, long-term safety, and therapeutic potential.",

Both conditions share overlapping pathophysiological mechanisms, including neuroinflammation, synaptic dysfunction, and circuit-level disturbances. Emerging evidence implicates blood-brain barrier (BBB) dysfunction as a potential common element in their pathogenesis. Specifically, BBB disruption is a recurring feature in preclinical models of SCZ and ASD, suggesting its role as a transdiagnostic mechanism in neurodevelopmental disorders. This systematic review aims to evaluate BBB alterations-including permeability, integrity, developmental changes, and tight junction (TJ) protein expression-in rodent models of SCZ- and ASD-like phenotypes. Following PRISMA guidelines, we screened experimental studies assessing BBB status in murine models of SCZ and ASD compared to wild type rodents. Inclusion criteria focused on models based on genetic manipulation and environmental insults. Included studies consistently reported BBB alterations across diverse models. Findings showed disrupted TJ protein expression (claudin-5, occludin, ZO-1), increased permeability, and endothelial dysfunction. Both genetic (e.g., Shank3, 22q11.2 deletion, etc.) and environmental (e.g., maternal immune activation, valproate exposure, etc.) models exhibited BBB abnormalities. Pharmacological and experimental interventions targeting the BBB-such as claudin-5 modulation or \u03b2-catenin signaling-ameliorated BBB damage and behavioral phenotypes. That BBB disruption is a recurring feature in preclinical models of SCZ and ASD suggests its pursuit as a transdiagnostic mechanism in neurodevelopmental disorders. However, as many findings rely on single studies, further replication is essential. Future studies should explore sex differences, critical developmental windows, and therapeutic strategies aimed at restoring BBB function.",

Siponimod, a potent sphingosine-1-phosphate (S1P) receptor modulator, is used to treat MS by reducing T-cell recirculation and central inflammation. The presented work includes clinical data describing the impact of the CYP3A4 inhibitor clarithromycin on siponimod metabolism and the results of updated physiologically based pharmacokinetic (PBPK) modeling. A clinical drug-drug interaction (DDI) study assessed the effect of clarithromycin on siponimod pharmacokinetics in healthy participants with the CYP2C9*1*3 genotype. Results revealed minimal differences in PK: a 2% increase in Cmax, an 8% increase in AUClast and a 9% increase in AUCinf, confirming no clinically relevant drug-drug interaction (DDI). The existing siponimod PBPK model was updated using these DDI study data, estimating a CYP3A4 fraction metabolized of 6.4% in the CYP2C9*1*1 genotype. Simulations using the updated PBPK model in the absence and presence of the restricted co-medication (CYP2C9 and CYP3A perpetrators) were conducted. There was no clinically relevant DDI with moderate and strong CYP3A4 inhibitors across CYP2C9 genotypes with a predicted maximum net AUC increase of 1.33. Co-administration of fluconazole, a moderate CYP3A4 and CYP2C9 inhibitor, was predicted to result in <\u20092-fold net AUC increase, except for the genotype CYP2C9*2*2, where a 2.2-fold net AUC increase compared to the CYP2C9 wild type without fluconazole co-treatment was observed. Siponimod Cmax and AUC were comparable across CYP2C9 genotypes during dose titration in the absence or presence of fluconazole, suggesting no impact on the effectiveness of the dose titration regimen.",
        "42370465": "ID: 42370465\nTitle: Evaluating the effectiveness of simvastatin in slowing the progression of disability in secondary progressive multiple sclerosis: a synopsis of MS-STAT2, a multicentre, randomised controlled, double-blind, phase 3 clinical trial.\nAbstract: Despite the relative success of immuno-modulatory disease-modifying therapy in relapsing remitting multiple sclerosis, progressive worsening of disability remains a major problem, particularly for those with secondary progressive multiple sclerosis. Various underlying mechanisms are likely to contribute, augmented by comorbidities (such as vascular risk) and ageing. In the phase 2b MS-STAT trial, simvastatin (80\u2005mg) (Sandoz Ltd, Camberley, UK) reduced the mean annualised whole brain atrophy rate by 43% compared to placebo in patients with secondary progressive multiple sclerosis (p\u2005=\u20050.003). We now report the phase 3, MS-STAT2 trial, with confirmed progression of disability as the primary outcome. A multicentre, phase 3, randomised, double-blind, placebo-controlled clinical trial was conducted at 31 UK neuroscience centres and district general hospitals. Secondary progressive multiple sclerosis participants aged 18-65 years were randomised 1\u2005:\u20051 to oral simvastatin (80\u2005mg), or matched placebo, based on a minimisation algorithm that incorporated the following factors: sex (male/female); age (< or \u2265\u200545 years); Expanded Disability Status Scale baseline score (\u2264\u20055.5 or \u2265\u20056); whether participants were taking newly licensed (2017 onward) disease-modifying treatments for secondary progressive multiple sclerosis; and trial site. An independent and secure online randomisation service was used. All participants, site investigators and the trial co-ordinating team were blinded to treatment allocation. The Expanded Disability Status Scale was measured every 6 months and was compared to baseline scores, with remote data collection used when enforced by the COVID-19 pandemic. The primary outcome was time to Expanded Disability Status Scale-confirmed disability progression. Progression of disability was defined as an increase of at least one point on the Expanded Disability Status Scale if the baseline score was <\u20056, or an increase of 0.5 point if the baseline score was \u2265\u20056. The initial disability progression event was finalised as confirmed if the increase in Expanded Disability Status Scale score persisted at the next assessments \u2265\u20056 months later. Follow-up was for 36 months, or 54 months, for those without confirmed disability progression at 36 months who agreed to enter an optional blinded extension. An intention-to-treat analysis was carried out. The study was conducted between 10 May 2018 and 26 July 2024. There were 964 participants randomised, with 482 in the placebo group and 482 in the simvastatin group. 173 (35.9%) participants in the placebo group and 192 (39.8%) participants in the simvastatin group experienced Expanded Disability Status Scale-confirmed disability progression (adjusted hazard ratio =\u20051.13, 95% confidence interval 0.91 to 1.39, p\u2005=\u20050.263). No material differences in the secondary outcomes were observed. No major safety issues were seen. The MS-STAT2 trial did not demonstrate a treatment effect of simvastatin in slowing disability progression in participants with secondary progressive multiple sclerosis. Despite the favourable outcomes of the previous phase 2b trial, simvastatin use in secondary progressive multiple sclerosis should be confined to existing vascular indications. This synopsis presents independent research funded by the National Institute for Health and Care Research (NIHR) Health Technology Assessment programme as award number 15/57/143. Multiple sclerosis is a lifelong condition that affects the brain and spinal cord. Many people with multiple sclerosis start with a type called relapsing-remitting multiple sclerosis, which can later become secondary progressive multiple sclerosis. Secondary progressive multiple sclerosis causes steady worsening of disability over time, and currently, there are very few treatment options for people without signs of active inflammation. Simvastatin is a cholesterol-lowering drug (a statin) that is widely used for heart disease. Earlier research (the Simvastatin in Secondary Progressive Multiple Sclerosis phase 2 trial) suggested that high-dose simvastatin might slow brain shrinkage and disability in people with secondary progressive multiple sclerosis. To test this further, researchers ran a large phase 3 clinical trial called Simvastatin in Secondary Progressive Multiple Sclerosis (phase 3 trial), involving 964 participants across the United Kingdom. Half were given simvastatin and half a placebo, and they were followed up while continuing to take these for 3 years. For participants whose disability was stable at 3 years, they could continue in the trial on the same medication for up to 4.5 years if they were happy to do so. The main aim was to see if simvastatin could slow down worsening disability, which was measured using a scale called Expanded Disability Status Scale. The Expanded Disability Status Scale data were mainly collected at face-to-face appointments, but some assessments were conducted by telephone when enforced by the COVID-19 pandemic. The results showed no significant difference between the simvastatin and placebo groups. Simvastatin did not delay disability progression. The trial also looked at other outcomes such as walking speed, hand function, memory and quality of life. Again, there were no meaningful differences. Importantly, simvastatin was generally safe, and side effects were rare. The trial also found that people with higher disability levels faced higher personal and financial costs, and many relied on unpaid care from family or friends. Overall, the Simvastatin in Secondary Progressive Multiple Sclerosis phase 3 trial provides clear evidence that simvastatin does not have a therapeutic effect in slowing disability progression in people with secondary progressive multiple sclerosis. It also offers valuable insights for future research into progressive multiple sclerosis and highlights the need for new treatments that target the disease\u2019s underlying causes.",

This study aimed to clone and express the catalase gene from Kocuria rhizophila ATCC 9341 into Escherichia coli BL21 (DE3), then characterize the purified enzyme and evaluate its potential for hydrogen peroxide degradation in textile wastewater. The 1524\u00a0bp gene was amplified and ligated into pET-21a(\u2009+) using the T4 DNA ligase enzyme. The expression of the recombinant catalase gene in E. coli BL21(DE3) was verified by using Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis, with an estimated molecular weight of 57\u00a0kDa. The purified enzyme demonstrated a specific activity of 109.55\u00a0U/mg, optimal activity at pH 7-7.5, and 50\u00a0\u00b0C. The enzyme showed significant stability up to 80\u00a0\u00b0C and in a wide range of pH (4.0-9.0) by retaining up to 70% activity. The enzyme was also found to be resistant to several organic solvents, EDTA, \u03b2-mercaptoethanol, and metal ions, but was inhibited by Cu2+ and Cr2+. In-silico studies, including 3D modeling, quality validation, and molecular docking with hydrogen peroxide, confirmed strong ligand interactions, aligning with the experimental data. The combined experimental and computational findings suggest the enzyme's potential for industrial applications, especially in bioremediation and oxidative treatments.",

In this work, two photodynamic polymer conjugates were synthesized by covalently attaching protoporphyrin IX (PPIX) and its zinc(II) complex (ZnPPIX) to branched polyethyleneimine (PEI), a polycationic polymer that promotes strong electrostatic interactions with bacterial surfaces. The resulting PEI-PPIX and PEI-ZnPPIX conjugates were characterized by FT-IR and 1H NMR spectroscopy, while UV-visible absorption and fluorescence measurements confirmed successful coupling and preservation of the photophysical properties of the porphyrin macrocycle. Both conjugates efficiently generated reactive oxygen species under visible-light irradiation. PEI-ZnPPIX exhibited a higher singlet oxygen quantum yield, consistent with the heavy-atom effect of the coordinated Zn(II). In addition, both systems promoted NBT reduction to diformazan in the presence of NADH, and effectively photosensitized L-tryptophan photooxidation. Photobleaching studies showed greater stability in biological media than in organic solvents, although the Zn(II) conjugate photodegraded faster than PEI-PPIX. Photodynamic inactivation assays against Staphylococcus aureus demonstrated that both conjugates achieved\u2009>\u20096 log (>\u200999.9999%) reductions in planktonic cultures at micromolar concentrations after short irradiation times under white light. Furthermore, treatment of Cucumis sativus (cucumber) surfaces contaminated with S. aureus using 2.5\u00a0nmol of these conjugates, followed by 30\u00a0min of irradiation, resulted in a reduction of more than 99.99% in bacterial viability. The elimination of S. aureus on cucumber mesocarp surfaces was further assessed by detecting individual damaged cells after photodynamic treatment. These findings highlight PEI-PPIX and PEI-ZnPPIX as promising photodynamic agents for enhancing microbial safety and potentially extending the shelf life of fresh produce.",

Its pathogenesis is driven by complex interactions between genetic susceptibility and environmental exposures. Investigating gene-environment (G\u2009\u00d7\u2009E) interactions holds significant potential to elucidate the regulatory genetic architecture underlying individual responses to environmental risk factors in childhood asthma. In this review, we systematically summarize the environmental exposure factors during prenatal and postnatal periods and analyze their independent effects on the risk of childhood asthma. Secondly, we explore the role of G\u2009\u00d7\u2009E interactions\u00a0in asthma from three perspectives: statistical interaction, mechanistic interaction, and epigenetic-mediated interaction. Finally, we evaluate current treatment and intervention strategies, distinguish established recommendations for the general population from emerging and exploratory methods, and point out existing limitations. Our analysis reinforces that investigating G\u2009\u00d7\u2009E interactions is a robust approach for uncovering the molecular mechanisms underlying childhood asthma. Despite substantial technical challenges and unresolved questions regarding generalizability and heterogeneity, such investigative strategies are expected to enhance our understanding of asthma endotypes and the development of more effective, precision-based preventive and therapeutic interventions.",
        "42385970": "ID: 42385970\nTitle: Toxicity assessment of three emerging bisphenols (BPA, BPAP and BPC) and their binary mixtures in an advanced in vitro 3D HepG2 cell model.\nAbstract: Bisphenols (BPs) are industrial chemicals extensively used in polycarbonate plastics and epoxy resins for everyday products, including food and beverage containers, toys, and thermal paper, representing major sources of human exposure. Bisphenol A (BPA) is the most prevalent; however, due to its endocrine-disrupting, reproductive, and genotoxic effects, it is classified as a substance of high concern by the European Chemicals Agency. Regulatory restrictions have prompted the use of structural analogues, including bisphenol AP (BPAP) and bisphenol C (BPC); however, emerging evidence suggests they may pose similar or greater health risks. Comprehensive data on their toxicity and human exposure, especially in mixtures, remain limited. This study assessed the cytotoxic and genotoxic effects of BPA, and less studied analogues BPAP, BPC, and their binary mixtures using a human-relevant 3D HepG2 spheroid model, representing an advanced in vitro system. Spheroids were exposed for 24 and 96\u202fh, and effects were evaluated by ATP-based viability assays, comet assay, and targeted transcriptomics. None of the bisphenols induced significant cytotoxicity, although slight reductions in viability were observed for BPAP, BPC, and mixtures. DNA strand breaks were detected after exposure to BPA, BPC, and mixtures. Transcriptomic analysis revealed modest stress responses and strong upregulation of xenobiotic metabolism genes (CYP1A1, CYP1A2, CYP3A4, UGT1A1, NAT2), indicating cellular recognition of the tested bisphenols as bioactive xenobiotics. Antioxidant and DNA repair genes were largely unchanged, except for upregulation of oxidative stress markers HMOX1 and SRXN1 and a slight increase in OGG1, indicating oxidative DNA damage. Importantly, mixture effects were predominantly additive, with no evidence of synergistic interactions under the tested conditions. Overall, bisphenol exposure primarily triggered oxidative stress and metabolic responses rather than robust DNA damage signalling, suggesting that genotoxicity is largely mediated by reactive oxygen species.

However, several questions remain unanswered, pertaining to the associations with PD of environmental factors that are still in use today; the added risks of co-exposure to multiple environmental factors and gene-environment interactions. Additional questions remain on the relevant time window, duration, and level of environmental exposures in relation to PD risk. Furthermore, it is unclear whether these exposures are associated with clinical progression of PD. PD-PEST (Parkinson's Disease-Preventing Emergence of Symptoms by environmental Toxicants) is a nationwide hospital-based case-control study conducted in the Netherlands. The study population consists of 1500 persons with a recent PD diagnosis and 3000 age- and sex-matched controls. Participants will be recruited from four regions across the Netherlands to ensure a representative geographical distribution in terms of urbanisation, industry, and agricultural activity. Cases must have a PD diagnosis, established by a neurologist in the Netherlands according to standard diagnostic criteria. Controls are outpatients with a different neurological condition that is unlikely to be associated with the environmental factors of interest or the risk of PD. We will collect detailed information on historical and current environmental exposures at an individual level. This includes occupational and residential histories (via questionnaires and nationwide registries) and measurements (blood, saliva, faeces, hair, and via silicone wristbands). Based on these multimodal data, we will estimate participants' individual lifetime exposure to environmental factors. Then, we will examine the associations between these exposures and the risk of PD. In addition, we will assess longitudinal associations between exposures and clinical progression of individuals with PD over 36 months. Analyses will be adjusted for possible confounders and multiple hypothesis testing. The PD-PEST study aims to overcome the limitations of previous studies by examining a large, representative study population, incorporating detailed information on clinical PD diagnosis, conducting extensive assessments of historical and current environmental risk factors and collecting detailed information on possible confounders. The results are expected to enhance our understanding of the role of environmental factors in the aetiology of PD and inform preventive strategies. The Medical Ethical Committee Oost-Nederland approved this study (NL86526.091.24). Informed consent will be obtained from each participant prior to participation in any of the study procedures. Findings of this study will be disseminated through publications, conferences, stakeholder briefings, and tailored communication materials for participants and the wider Parkinson community.

As cannabinoids inhibit glutamate release in the striatum, they may represent an effective therapeutic option for RLS. Evaluate the efficacy of 2.7\u00a0mg \u03949Tetrahyedrocannabinol/2.5\u00a0mg Cannabidiol (2.7mgTHC/2.5mgCBD) in RLS. This is an exploratory, prospective, 3-month open-label trial. At baseline, patients underwent blood testing, respiratory polygraphy, and a 14-day actigraphy. Treatment was initiated at baseline, with dose titration at week 4 if required. The Expanded Disability Status Scale (EDSS), Epworth Sleepiness Scale (ESS), International Restless Legs Syndrome Rating Scale (IRLS), Modified Ashworth Scale, and EQ-5D were assessed at baseline and at weeks 4 and 12. The 14-day actigraphy was repeated at week 12. The primary endpoint was improvement in IRLS scores. Sleep parameters were evaluated as secondary endpoints. Primary end point: improvement in IRLS. Sleep parameters were secondary end points. Eighteen patients with RLS were included, of whom 16 had multiple sclerosis (MS). The cohort comprised 55.5% women, with a mean age of 51.87\u00a0years, a median EDSS score of 2, and a mean Ashworth score of 1\u2009\u00b1\u20091.19. Median iron metabolism parameters were within the normal range. At baseline, patients exhibited low daytime sleepiness (ESS: 10.63\u2009\u00b1\u20093.46) and severe RLS (IRLS: 22.44\u2009\u00b1\u20098.77).

IRLS scores improved significantly after both 1 month and 3 months of treatment (p\u2009<\u20090.001). WASO was significantly reduced (p\u2009=\u20090.015), whereas no significant changes were observed in SL or SE. After 1\u00a0year, 66.66% of patients remained on treatment and continued to show sustained improvement in IRLS scores (p\u2009=\u20090.000). In this exploratory open-label study, treatment with 2.7\u00a0mg THC/2.5\u00a0mg CBD was effective in reducing RLS severity, as measured by the IRLS scale, in patients with MS and-associated idiopathic RLS.

Hematoxylin and eosin(HE) staining was used to assess inflammatory cell infiltration, while luxol fast blue(LFB) staining and electron microscopy were performed to evaluate myelin sheath structure. In cell experiments, this study measured programmed cell death ligand 1(PD-L1) expression on BV2 cells and forkhead box protein p3(Foxp3) expression in Jurkat T cells co-cultured with BV2 cells, determined the C-C motif chemokine ligand 5(CCL5) concentration in the supernatant of BV2 cells, and evaluated BV2 cell chemotaxis. Western blot(WB) was performed to detect protein levels of receptor tyrosine kinase(AXL), phosphorylated AXL(p-AXL), signal transducer and activator of transcription 1(STAT1), phosphorylated STAT1(p-STAT1), and suppressors of cytokine signaling 3(SOCS3). To confirm the role of AXL, key cellular assays were repeated following inhibition of AXL. Additionally, under physiological conditions, the effects of DHA on body weight, spleen weight, and peripheral blood immune cell profiles were examined. The results showed that DHA significantly reduced disease scores, attenuated body weight loss, suppressed inflammatory infiltration, and promoted myelin sheath repair in experimental autoimmune encephalomyelitis(EAE) mice. At the cellular level, DHA upregulated PD-L1 expression on BV2 cells and Foxp3 expression in co-cultured Jurkat cells, and inhibited CCL5 release and BV2 cell chemotaxis. It also upregulated AXL, p-AXL, p-STAT1, and SOCS3 protein expression in BV2 cells. When AXL was inhibited, these effects are nullified. In healthy mice, DHA did not have any effect on their various parameters. In conclusion, DHA maintains inflammatory homeostasis in the EAE model by activating the AXL signaling pathway in microglia.",

Dietary habits, reproductive characteristics, and physical activity have been proposed as potential contributors to MS susceptibility. This study aimed to investigate the association of dietary intake, supplement use, reproductive factors, and physical activity with MS in Kermanshah Province, Iran. This case-control study included 600 participants (300 MS patients and 300 matched healthy controls) from Kermanshah. Data were collected using the validated Persian version of the Environmental Exposure and Lifestyle Risk Factors in MS Questionnaire (EnvIMS-Q). Logistic regression analyses were performed to estimate crude and adjusted odds ratios (ORs) with 95% confidence intervals (CIs). Compared with controls, participants with MS reported lower consumption of several foods, including fish (adjusted OR\u2009=\u20090.31, 95% CI 0.19-0.50), seafood (adjusted OR\u2009=\u20090.31, 95% CI 0.10-0.98), nuts (adjusted OR\u2009=\u20090.60, 95% CI 0.39-0.93), and dairy products. Fish oil supplementation was less common among patients with MS (adjusted OR\u2009=\u20090.28, 95% CI 0.13-0.61). Female patients reported higher frequencies of oral contraceptive use, miscarriage, and assisted reproduction. Vigorous physical activity was significantly lower among patients than controls, whereas mild physical activity did not differ significantly. No significant association was observed for vitamin D supplementation. This study identified associations between several dietary, reproductive, and lifestyle factors and MS in a high-prevalence region of Iran. Lower consumption of selected nutrient-rich foods, lower fish oil supplement use, certain reproductive factors, and lower levels of vigorous physical activity were associated with higher odds of MS. Prospective studies are needed to clarify temporal relationships and causality.",

To examine whether the effect of smoking on disability progression differs according to HLA-A*02:01 and HLA-DRB1*15:01 status. Patients from two population-based case-control cohorts were classified by smoking status at diagnosis and by HLA-A*02:01 and HLA-DRB1*15:01 status and were followed for up to 15\u2009years through the Swedish MS registry (n\u2009=\u20096807). Cox regression models were used to estimate hazard ratios (HRs) with 95% confidence intervals (CIs) for 24-week confirmed disability worsening (CDW) and time to Expanded Disability Status Scale (EDSS) 3, 4, and 6. Interaction was assessed on the additive scale. Compared with HLA-A*02:01-positive non-smokers, smoking at diagnosis was associated with a higher risk of disability progression primarily among individuals who lacked HLA-A*02:01, with consistently elevated risks of CDW (HR\u2009=\u20091.15, 95% CI\u2009=\u20091.06-1.26), EDSS 3 (HR\u2009=\u20091.26, 95% CI\u2009=\u20091.08-1.47), and EDSS 4 (HR\u2009=\u20091.50, 95% CI\u2009=\u20091.25-1.79). No clear effect of smoking was observed among HLA-A*02:01 carriers, and no evidence of interaction was detected between smoking and HLA-DRB1*15:01. These findings suggest that the impact of smoking on MS progression varies according to immunogenetic background.",
        "42400730": "ID: 42400730\nTitle: Neuroprotective potential of resveratrol in Parkinson, Huntington, amyotrophic lateral sclerosis, and multiple sclerosis: a comprehensive review.\nAbstract: Resveratrol shows neuroprotective effects in preclinical studies across a number of neurodegenerative illnesses, including Parkinson's disease (PD), Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), and Huntington's disease (HD), and it enhances mitochondrial function through stimulation of the AMPK/SIRT1/PGC-1\u03b1 pathway, thereby improving mitochondrial oxidative capacity and ATP generation. The natural polyphenol lowers \u03b1-synuclein accumulation and affects autophagy; both markers of PD. Combining nano\u2011resveratrol formulations with L\u2011DOPA has shown greater therapeutic efficacy in animal models (MPTP mouse), while co\u2011administration with EGCG has shown synergistic neuroprotection in vitro (SH\u2011SY5Y cells). These combination strategies offer potential advantages in neuroprotection and symptom alleviation while minimizing adverse drug effects. Resveratrol activates SIRT1 and AMPK signaling in preclinical models, enhancing mitochondrial biogenesis, lowering apoptosis, and restoring cellular resilience. The effectiveness of various models and dosages varies. The primary mechanism by which resveratrol promotes neuronal survival and remyelination in multiple sclerosis is through SIRT1 activation, which does not directly reduce inflammation. As innovative delivery systems, intranasal nanoparticles and exosomes produced from macrophages have shown improved CNS targeting accuracy. Resveratrol slows down neurodegeneration and improves the prognosis of HD by improving motor function and stimulating mitochondrial biogenesis in addition to activating neuroprotective ERK signaling. All of these results point to resveratrol's several pathways as a strong contender for neurodegenerative disease adjunctive treatment. The current evidence base is insufficient to support clinical use of resveratrol for any of the four diseases. Further rigorous preclinical studies (including TDP-43 models for ALS, SIRT1 knockout studies, and human-feasible dosing) and well-designed clinical trials with pharmacokinetic endpoints are required before any clinical recommendations can be made.",

These manifestations partially resemble motor dysfunction in multiple sclerosis (MS). Panax quinquefolius Saponins (PQS), are major bioactive constituents, but their effects on demyelination and related molecular changes remains unclear. To investigate the effects of PQS on demyelination and explore associated changes in inflammatory signaling and lipid metabolism. PQS was qualitatively profiled by UPLC-QTOF-MS and quantitatively standardized by HPLC-DAD. Male C57BL/6N mice were randomly divided into six groups (n\u202f=\u202f12-16/group): Control, Model (daily intragastric administration of 330\u202fmg/kg of cuprizone (CPZ) for 6 weeks), Positive control (10\u202fmg/kg of Clemastine), and low-, medium-, and high-dose PQS groups (25, 50, or 100\u202fmg/kg). During week 2-6, mice received drugs by daily intragastric administration. Behavioral assessments including pole test, rotarod, and open field test were performed. Myelin integrity and related molecular changes were evaluated by histological staining, immunofluorescence (IF), transcriptomics, Western blotting, and molecular docking. PQS ameliorated CPZ-induced motor dysfunction in behavioral assessments (P\u202f<\u202f0.05). PQS also attenuated myelin loss in the corpus callosum (CC), with the high-dose group increasing myelinated areas to approximately 74% of control levels (P\u202f<\u202f0.01). Transcriptomic and protein analyses showed that PQS downregulated JAK1/STAT3/NLRP3 inflammatory pathway. In parallel, the HMGCS1-NPC1-MAL axis was upregulated, accompanied by increased mevalonate (MVA) and total cholesterol (TC) levels (P\u202f<\u202f0.05) and reduced PLIN2 expression (P\u202f<\u202f0.001), suggesting decreased lipid droplet accumulation and altered cholesterol metabolism.Molecular docking predicted ginsenosides Rb3, Rk3, Re, Rc, Ro, and Rf may interact with targets related to inflammatory and lipid metabolism. PQS supported myelin restoration, which is correlated with a modulation of the JAK-STAT signaling pathway and HMGCS1/NPC1-associated lipid homeostasis. PQS may represent a potential therapeutic lead for demyelinating diseases, although mechanisms require further validation.",

This process leads to mitochondrial dysfunction, oxidative stress, and neuronal death. Uric acid (UA) has been identified as a potential neuroprotective molecule due to its antioxidant properties, but its limited solubility poses challenges for clinical use. To address this issue, we encapsulated UA in poly (lactic-co-glycolic acid) nanoparticles (UA-NPs) using a modified double emulsion technique to enhance stability and delivery of UA. Spinal cord cultures were subjected to GIE, followed by treatment with UA-NPs or empty nanoparticles. Neuronal survival was assessed with immunocytochemistry for the neuronal marker microtubule-associated protein 2 (MAP2), which revealed that treatment with UA-NPs resulted in significantly higher cell survival compared to cultures treated with empty nanoparticles. These findings suggest that UA-NPs provide neuroprotection to spinal cord neurons in\u00a0vitro and may serve as a promising localized drug delivery system for SCI treatment, offering a targeted approach to mitigate secondary injury. Spinal cord injuries can cause long-term damage not only from the initial injury but also from secondary injury processes that worsen the condition over time. One of these processes involves glutamate, an important neurotransmitter normally present in cells. However, when released in excess, glutamate can overstimulate nearby neurons and lead to damage and death of nerve cells. This process can harm essential cell functions, increase stress within cells, and reduce their ability to survive. Uric acid is a natural substance in the body that can help protect cells because of its antioxidant properties. However, it does not dissolve well in water-based solvents, including blood, making it difficult to use as a treatment. To overcome this problem, we packaged uric acid into tiny particles called nanoparticles, which improve its stability and delivery to cells. In this study, we tested our uric acid-loaded nanoparticles on spinal cord cells after exposing them to harmful conditions similar to those seen after injury. We found that cells treated with these nanoparticles survived better than those treated with empty particles. These results suggest that delivering uric acid using nanoparticles may help protect nerve cells after spinal cord injury. This approach could lead to more effective treatments that target and reduce further damage after the initial injury.",

This prospective cohort was designed to address knowledge gaps regarding how eco-environmental and lifestyle factors influence ageing trajectories. GEHAS enrolled 5645 participants (59.8% women; mean age 62.51 years) from Guilin, Guangxi, at baseline, with Yao and Han participants accounting for 60.3% and 36.2% of the cohort, respectively. Baseline data (2018-2022) included questionnaires, physical examinations, biological specimens (blood, urine, hair and nails). Two subsequently established longevity and circadian rhythm sub-cohorts (n=276 and n=596) underwent multi-omics profiling (genomics, epigenomics, proteomics, metabolomics and exposomics). Follow-up in this open cohort includes active surveys approximately every 5 years and annual passive surveillance through government health registries. Recent analyses highlight that improvements in air quality can mitigate frailty progression in older adults, with DNA methylation emerging as a promising biomarker that captures the biological imprint of environmental policy interventions and ageing dynamics. In parallel, local specialty foods and traditional dietary practices have been implicated as potential contributors to reducing the risk of ageing-related diseases, as demonstrated by multiple studies using baseline data. For instance, oil tea consumption has shown potential protective effects against dyslipidaemia and type 2 diabetes, while region-specific dietary patterns were associated with favourable health outcomes in middle-aged and older adults. Specifically, a dose-dependent association was observed between diets rich in vegetables and mushrooms and enhanced cognitive performance, and antioxidant-rich dietary patterns were found to attenuate biological ageing through modulation of redox homeostasis. Moreover, GEHAS studies also explored the interactions between genetic factors and heavy metal exposures in age-related diseases, underscoring the complex interplay between genetic susceptibility and environmental influences in the ageing process. GEHAS will continue active follow-up surveys every 5 years, supplemented by annual passive surveillance for morbidity and mortality through health registries. The first active follow-up was initiated in 2023 and will continue until 2026/2027, with subsequent rounds planned thereafter.

Following the elucidation of the role of B cells in MS pathogenesis, B-cell-depleting agents such as Rituximab have become increasingly utilized. However, the relationship between rituximab therapy and susceptibility to tuberculosis (TB) remains a subject of ongoing investigation, with conflicting evidence in the literature. A 55-year-old Iranian woman with multiple sclerosis who had received rituximab for five years presented with high-grade fever, chills, and suprapubic pain. One year before admission, she had developed lower-extremity skin lesions initially diagnosed as eosinophilic fasciitis and later revised to erythema nodosum. Computed tomography revealed a left ovarian mass, a right ovarian cyst, ascites, pulmonary involvement, and bilateral pleural effusions, raising concern for malignancy. Bronchoalveolar lavage polymerase chain reaction confirmed tuberculosis. The patient was treated with the World Health Organization standard anti-TB regimen (isoniazid, rifampin, pyrazinamide, and ethambutol). Rituximab was discontinued; dimethyl fumarate was introduced after four months of therapy and rituximab was reintroduced at six months. At one-year follow-up, there was no TB reactivation and no worsening of MS. This case demonstrates an atypical multisystem presentation of tuberculosis in an immunocompromised patient receiving long-term anti-CD20 therapy. Susceptibility was likely multifactorial, including immunosuppression, occupational exposure, MS-related immune dysregulation, and prior corticosteroid use. Clinicians should maintain a high index of suspicion for atypical tuberculosis in immunocompromised patients receiving biologic therapies.",

Building on this expanding body of work, our review synthesises findings across studies and provides an integrated overview. Here, we present a structured literature review summarising study characteristics and statistically significant single nucleotide polymorphisms (SNPs) reported in gene-environment interaction studies of air pollution related respiratory outcomes. By consolidating this evidence, the review clarifies current findings and supports more rigorous, evidence-based risk stratification in future observational and intervention studies. We included 48 peer-reviewed studies in humans published between 2014 and 2024 that examined gene-environment interactions involving SNPs, outdoor air pollution exposure and respiratory outcomes. Studies primarily evaluating particulate matter with aerodynamic diameter <2.5\u2005\u00b5m and <10\u2005\u03bcm, and nitrogen dioxide included respiratory end-points, such as asthma, COPD and lung-function measures. The majority of analyses used regression-based methods, supplemented by mixed-effects and generalised estimating equation models. Candidate gene studies (particularly in the glutathione S-transferase (GST) family) along with polygenic risk scores and genome-wide interaction approaches identified 89 SNPs across 53 genes. Replicated variants involved pathways in oxidative stress detoxification (e.g. rs1695 (GSTP1) and rs2266637 (GSTT1)) and inflammatory responses (e.g. rs1800629 (TNF), rs3804099 (TLR2) and rs848 (IL13)), consistently modifying pollution-related lung function decline and airway inflammation. By consolidating key genes, study designs and analytic methods, this review provides a curated SNP list to inform future genetic risk stratification. We highlight the need for studies in ancestrally diverse populations, controlled human exposure designs, and multi-omics approaches to strengthen mechanistic understanding of gene-environment interactions in respiratory health.",

Some primary studies show an increased risk from long-term outdoor air pollution exposure, while others contradict this association. A systematic review and meta-analysis were undertaken to assess the associations of long-term (\u22651 year) outdoor air pollution exposure with PD, MS and MND incidence. We searched eight databases for publications up to July 2025. Primary case-control, cohort, cross-sectional or ecological studies investigating the association between long-term air pollution exposure and adult (>18\u00a0years old) PD, MS, or MND incidence were included.

This systematic review reports increased PD risk from long-term PM2.5 and PM10 exposure. No association was observed for MS and MND from a very limited evidence base. The neurodegenerative diseases investigated here are rare and therefore alternatives to insufficiently powered cohort studies are needed to strengthen the evidence on risk.",

Epstein-Barr virus (EBV) infection has been implicated as a major environmental risk factor in MS pathogenesis. Despite the availability of disease-modifying therapies, effective targeted interventions for progressive disease remain limited. In this study, an EBV-informed integrative computational framework combining MS transcriptomic datasets, EBV-associated transcriptional signatures, GWAS susceptibility genes, and network analyses was employed to identify molecular targets associated with immune dysregulation in MS. RNA-sequencing datasets related to MS and EBV infection were obtained from the GEO database, whereas MS susceptibility genes were retrieved from the GWAS Catalog. Differential expression analysis identified 275, 200, and 773 significant DEGs in CD4\u207a T cells, CD8\u207a T cells, and CD14\u207a monocytes, respectively, along with 8,633 EBV-associated DEGs. Integrative overlap and enrichment analyses revealed convergence at the pathway level, particularly involving B-cell receptor signaling, Fc receptor activation, antigen presentation, complement activation, and inflammatory immune signaling. Hub gene analysis identified IL6, CD86, CD28, and PTPN11 as central regulatory nodes. Based on biological relevance and structural tractability, PTPN11/SHP2 was selected as the final therapeutic target. Structure-based drug repurposing identified Gusperimus as the top-ranked ligand, exhibiting a favorable docking score (-\u20099.287\u00a0kcal/mol) and a broader interaction profile within the SHP2 allosteric pocket relative to the reference inhibitor SHP099 (-\u20097.915\u00a0kcal/mol). Molecular dynamics simulations supported stable occupancy of the SHP2 allosteric pocket by Gusperimus over a 100 ns trajectory. Collectively, these findings highlight SHP2 as a potential therapeutic target and identify Gusperimus as a candidate for further investigation in MS-associated immune dysregulation.",

Gene-environment interactions were assessed in a subset of 60,017 participants with available genotyping data using Cox proportional hazards models. Over a median follow-up of 4.6 years, 11,127 CAD events were recorded. Each 10-\u03bcg/m3 increase in PM2.5 exposure was associated with a 14% higher hazard of incident CAD (hazard ratio [HR]: 1.14, 95% CI: 1.08-1.20), and each standard deviation increase in PRS was associated with a 7% higher hazard of incident CAD (HR: 1.07, 95% CI: 1.05-1.10). In joint analyses, PM2.5 exposure and genetic susceptibility each independently contributed to CAD hazard without significant interaction, with the highest hazard observed among individuals with both high PRS and high PM2.5 exposure (HR: 1.24, 95% CI: 1.14-1.36). Long-term PM2.5 exposure and polygenic susceptibility each independently contributed to the hazard of incident CAD, and individuals with both high genetic risk and high PM2.5 exposure had the highest observed hazard. These findings suggest that environmental exposure reduction and genetic risk identification may serve as complementary approaches to CAD prevention, particularly in populations with substantial air pollution burden.",

Shift work disrupts circadian rhythms and is a potential occupational risk factor for MS, with exposure before age 20 thought to be of additional risk. To investigate associations between retrospective lifetime shift work exposure and MS diagnosis and between prospective shift work exposure and incident MS over 13 years of follow-up in the UK Biobank cohort. Participants that were in work and free of MS at baseline were followed up for 13 years, and lifetime exposure to night, day and mixed shift work was assessed in a subset of participants. Logistic regression and Cox proportional hazard models were applied to test associations between shift work and MS diagnosis, controlling for demographic and lifestyle confounders. Lifetime exposure to mixed, day or night shift work was not associated with an increased risk of MS diagnosis. No significant associations were observed for early-life shift work exposure or in prospective analysis of those reporting shift work at baseline. Factors such as female sex, smoking, childhood obesity and reduced sunlight exposure were consistently associated with higher MS risk. There was no evidence for an association between shift work and the risk of MS diagnosis in this cohort, in retrospective analysis of lifetime exposure or in prospective studies of shift work at baseline following 13 years of follow-up. Further research is needed to elucidate mechanisms and latitudinal variations in shift work-related MS risk.",

This review examines how SARS-CoV-2 infection influences the incidence, progression, and outcomes of five major autoimmune conditions: systemic lupus erythematosus, rheumatoid arthritis, multiple sclerosis, inflammatory bowel disease, and Guillain-Barr\u00e9 syndrome. Patients with autoimmune diseases are at increased risk of severe COVID-19 due to intrinsic immune dysregulation and the use of immunosuppressive therapies, both of which impair antiviral host defenses. Conversely, COVID-19 has been implicated in the initiation and exacerbation of autoimmune responses through mechanisms such as molecular mimicry and bystander activation. Concerns have also arisen regarding the safety and efficacy of COVID-19 vaccines in immunocompromised populations. Although vaccines are generally tolerated in these individuals, certain immunosuppressive therapies may attenuate humoral and cellular immune responses. Strategies such as adjusting immunosuppressive regimens and optimizing the timing of vaccination have been proposed to improve vaccine efficacy. Disease-specific considerations are essential to balance infection risk with adequate control of autoimmune activity. Overall, this review underscores the importance of individualized treatment strategies, close clinical monitoring, and interdisciplinary care in managing patients with autoimmune diseases during the COVID-19 pandemic. A deeper understanding of these interactions will be critical for improving patient outcomes and preparing for future pandemics involving immune-mediated diseases.",

The majority of research on environmental risk factors in PD is focused on adult exposures, largely reliant on recall from occupational or lifestyle factors. However, because PD is a progressive disorder with prolonged preclinical and prodromal phases, exposures that contribute to PD risk are likely to occur long before symptom onset, including during early life. According to the developmental origins of health and disease (DoHAD) hypothesis, exposures that occur at critical periods of neurodevelopment can produce long-lasting changes that contribute to neurological disease. While these effects are studied mainly in the context of neurodevelopmental disorders, these effects can persist to affect risk for late-onset disease. Here, we review existing literature on the impact of developmental and early-life exposures to well-established PD-related toxicants to assess the state and rigor of the extant literature and highlight the need for future studies to evaluate the impact of early-life exposures to specific toxicants across the lifespan, particularly for later-life neurodegeneration. Overall, existing data shows that, in addition to their adult neurotoxicity, PD-related toxicants also produce persistent developmental neurotoxicity. However, a \"neurodegeneration gap\" exists as few developmental studies have evaluated dopaminergic dysfunction specifically, neurodegeneration-relevant outcomes, or the effects of aging. In addition, the existing literature is plagued by methodological and reporting issues that limit interpretation and hinder progress in this field. Future research must prioritize standardized reporting, environmentally relevant dosing, and the incorporation of aging to determine if these early life exposures contribute to persistent and latent neurotoxicity relevant to PD.",

Its assessment is essential for studying development, plasticity, and repair of the nervous system (NS), and for diagnosing demyelinating diseases and evaluating remyelination therapies. Multiple histological methods detect myelin, each with trade-offs in sensitivity, cost, and reproducibility. Among them, Eriochrome Cyanine R (EC-R) is a simple, affordable myelin stain widely used in thin sections, but remains poorly standardized, and underexplored in thick vibratome sections. Here we describe and validate a simple, inexpensive, solvent-free EC-R protocol for central and peripheral nervous system tissue across seven vertebrate species and multiple demyelinating conditions. The method replaces subjective microscopic differentiation with fixed, time-controlled incubations scaled to section thickness, improving reproducibility. Using perfusion and immersion-fixed samples, we show that the protocol yields homogeneous myelin labeling with sharp white/gray matter contrast in whole brains, cortical slabs, spinal cord, and peripheral nerves. Thick sections stained with EC-R preserve 3-dimensional tissue architecture, resolve single myelinated axons and intracortical bands, and can be combined with Nissl-like counterstains and immunohistochemistry. Developmental series in neonatal rats reveal expected PNS-CNS myelination gradients, while experimental demyelination models and naturally occurring diseases (canine distemper and human multiple sclerosis) illustrate the method's ability to delineate lesion cores, perilesional gradients, and associated glial and immune activation. This standardized EC-R approach provides a robust and versatile tool for comparative neuroanatomy, experimental neuropathology, and translational studies of myelination, demyelination, and remyelination, as well as for the clinical diagnosis of myelin-related disorders.",

However, its effects on pentylenetetrazole (PTZ)-induced seizure and associated oxidative brain damage remain unclear. To evaluate the anticonvulsant effects of nerolidol on PTZ-induced seizures in mice and to investigate its impact on oxidative and nitrosative stress markers in the hippocampus and cortex. Male mice were divided into 5 groups: control, PTZ, and PTZ pretreated with nerolidol (25, 50, or 100\u2009mg/kg, orally) 30\u2009minutes before PTZ administration. Seizure activity was assessed by measuring latencies to minimal clonic seizures (MCSs) and generalized tonic-clonic seizures (GTCSs). After a behavioral evaluation, hippocampal and cortical tissues were analyzed for malondialdehyde (MDA), nitric oxide (NO) metabolites, superoxide dismutase (SOD), catalase (CT), and total thiol content. Nerolidol significantly increased MCS and GTCS latencies compared with the PTZ group. In the hippocampus, all doses reduced MDA levels, while in the cortex this effect was observed at 50 and 100\u2009mg/kg. Nitric oxide metabolites were decreased by the two higher doses in both brain regions. The PTZ-induced reductions in SOD and CT activities were reversed by nerolidol at all doses, and total thiol levels were restored at 50 and 100\u2009mg/kg. Nerolidol exhibits anticonvulsant and neuroprotective effects on PTZ-induced seizures, likely mediated by reduced oxidative and nitrosative stress and enhancement of endogenous antioxidant defenses.",

In a rapidly advancing field in which diverse multinational cohorts and molecular methods have been created, highly resolved microbial traits such as protein function and strain genetics can now be investigated through meta-analysis. We integrated 2371 stool metagenomes from 542 individuals with IBD and their referent counterparts from the United States, Canada, and Europe, using all 7 IBD cohorts in the Human Microbiome Bioactives Resource, which we interrogated using taxonomic, functional, and strain profiling. We systematically identified the mass expansion of proinflammatory, oral-predominant taxa in the IBD gut, such as Veillonella and Streptococcus spp. We also accurately discriminate CD from UC, a clinically challenging problem, using highly resolved microbial strain genetics (area under the curve = 0.69). Further, we observed disease-specific shifts in carbohydrate metabolism, a likely consequence of small bowel dysfunction in CD, but not UC, as well as perturbations in mucin use, increased microbial virulence and invasion cassettes, and loss of carnitine degradation pathways in IBD. Finally, we observed novel and significant differences in the gene carriage among both IBD- and non-IBD-associated taxa, suggesting that strain-specific functional variation may contribute to pathogenesis and disease-related bacterial fitness. Microbial clades responsible for IBD-linked dysbiosis are not uniform, and their functionality in IBD and CD/UC subsets are driven by species and strain lineage-specific variants.",

The central nervous system is rich in lipids, and they are evidently disturbed in neurological conditions and neurodegenerative diseases like Alzheimer's disease (AD). Alteration in lipid profile is highly linked with aging. During early onset of AD, there is a noted lipid peroxidation and modifications of fatty acids at the level of lipid rafts in the neuronal cells. AD is an age-linked neurodegenerative condition with multifaceted etiology, with combining genetic and environmental risk factors, which lacks disease-modifying therapies. While the aberrant deposition of lipids was shown in the initial studies of AD neuropathology. Clinically, lipidomic and metabolomic research have constantly exposed the changes in the levels of various lipid classes emerging in early onset of AD individuals. Also, decades of investigations have discovered multifactorial link between lipid metabolism and key AD pathogenic pathway such as amyloidogenesis, bioenergetic deficit, oxidative stress, neuroinflammation, and myelin degeneration. Herewith, we highlighted the features that impact lipid composition in neuronal cells, and the association of different lipids with known aspects of AD pathogenesis, and potential therapeutics that aim lipid crossroads.",

Emerging evidence implicates chemotherapy-induced gut microbiota dysbiosis in CIPN pathogenesis via a gut-nerve axis. Concurrently, rectal ozone insufflation (ROI) has been shown to modulate the gut microbiota and reduce inflammation in preclinical models. This article critically examines the evidence on the role of gut dysbiosis in CIPN, evaluates the microbiota-modulating capacity of rectal ozone therapy (OT), and assesses the biological plausibility of ozone as a microbiota-targeting intervention for CIPN, while explicitly distinguishing between established evidence and hypothetical mechanisms. Neurotoxic agents induce dysbiosis marked by reduced microbial diversity, loss of short-chain fatty acid-producing bacteria, and expansion of pro-inflammatory taxa. Preclinical models demonstrate a causal role for specific microbial communities in CIPN, with microbiota depletion or fecal transplantation modulating neuropathic phenotypes. In human cohorts, dysbiosis severity correlates with CIPN symptoms. Preclinical studies show that ROI restores microbial balance, enhances short-chain fatty acid levels, and strengthens intestinal barrier function via Nrf2/HO-1 and SIRT1 pathways. Preliminary retrospective data from small case series (n = 7 and n = 15) report sustained symptom improvement in CIPN patients receiving OT. However, no human study has directly linked ozone-induced microbiota changes to clinical outcomes, and the clinical evidence for OT in CIPN remains limited to uncontrolled observations. Convergent preclinical evidence supports a biological rationale for investigating ROI as a microbiota-targeting intervention in CIPN. However, this rationale remains largely hypothetical in the clinical setting. High-quality randomized controlled trials with longitudinal microbiome profiling are urgently needed to establish mechanistic causality and to determine whether the promising preclinical findings translate into clinically meaningful benefits. Until such evidence is available, the framework presented here should be regarded as hypothesis-generating rather than as a basis for clinical practice.",

Unlike traditional chronic kidney disease (CKD), CKDu occurs without common risk factors such as diabetes, hypertension, or kidney stones. Its etiology remains poorly understood, with environmental exposures, occupational hazards, and genetic susceptibility proposed as contributing factors. Omic technologies including genomics, transcriptomics, proteomics, metabolomics, and exposomics offer promising avenues to elucidate CKDu pathogenesis by enabling comprehensive molecular profiling and identification of biomarkers. Recent genomic studies have explored single nucleotide polymorphisms (SNPs) linked to kidney injury susceptibility, while transcriptomic analyses have identified differential expression of genes involved in oxidative stress and tubular injury pathways. Proteomic investigations have revealed candidate urinary biomarkers such as heat shock proteins and inflammatory mediators, and metabolomic profiling has highlighted alterations in amino acid and energy metabolism in affected individuals. Exposomic approaches are beginning to characterize cumulative chemical exposures, including pesticides and heavy metals, in endemic regions. This narrative review synthesizes current evidence on the application of omics approaches in CKDu research, highlights knowledge gaps, and proposes future directions for integrating multi-omics studies with machine learning and artificial intelligence approaches. Advancing omics-based investigations may provide critical insights into disease mechanisms, improve diagnostic precision, and inform targeted interventions for vulnerable populations.",

Several fall risk factors have been identified, but the issue is complex, with interactions between triggering factors and preceding activities and events. There is a lack of studies explicitly evaluating fall prevention strategies given as counselling over time. The project includes (1) a two-armed randomised controlled internal pilot study with a nested qualitative study on participants' experiences and (2) a randomised controlled trial (RCT). The pilot study will evaluate feasibility in terms of recruitment, dropout, adverse events and battery of tests and will constitute a basis for recalculating the preliminary estimated sample size for a full-scale study. The RCT study will evaluate whether fall prevention strategies based on individual fall risk evaluation reduce fall frequency compared with general fall prevention information. Participants in the intervention group will have an extensive discussion with a physiotherapist regarding the impact of specific MS symptoms, environmental and personal factors, triggering factors and activities and/or circumstances that they perceive to precede fall situations; these discussions will then lead to the creation of individual strategies. In case of falling during follow-up, further discussions on strategies will be held by phone contact. The control group will receive general fall risk prevention recommendations. After completion of the study, the control group will be offered individual strategies based on reported falls. Participants in the pilot study allocated to the intervention group will after follow-up be invited to individual interviews focusing on experiences of taking part in the intervention and the study.Adults diagnosed with MS, fall history and remaining walking ability will be recruited by physiotherapists from six sites in Sweden. The primary outcome will be self-reported falls for 6 months and secondary outcomes will be self-rating scales covering concern about falling, confidence in remaining balance during activities, walking limitations and ability to avoid falls. Descriptive measures of disease impact will be used. The study was approved by the Swedish Ethical Review Authority, Stockholm Dept. 4 (ID: 2025-04486-1, date: 2025-08-12).

This review provides an ordered critical scoping synthesis of the current evidence on the environmental fate, food-chain transfer, dietary exposure, biomonitoring applications, mechanistic toxicology and cumulative risk assessment of priority PTEs in agricultural and aquatic food systems. Emphasis is given to the transfer of environmental contamination into biologically relevant exposure via crop uptake, contaminated water, livestock transfer and aquatic bioaccumulation. The review critically discusses limitations of conventional risk assessment frameworks of single contaminants, emphasizing the importance of bioavailability, mixture toxicity, chronic multi-pathway exposure, and population vulnerability in determining real-world risk. Biomarker-based approaches are explored for their utility in linking environmental contamination with internal exposure and early biological response. Mechanistic toxicology is considered in the context of food safety and cumulative risk interpretation. Major knowledge gaps remain in integrating environmental monitoring, biomonitoring, dietary exposure assessment, and mixture-based risk characterization within operational surveillance systems. Advancing toward biologically informed, exposure-realistic, and integrated risk assessment frameworks will be essential for improving food safety management and long-term resilience of contaminated food production systems. \u00a9 2026 Society of Chemical Industry.",

A powerful step in uncovering the molecular basis of biological processes is the execution of discovery screens in model systems. Here, we employed zebrafish to identify molecules that regulate axon diameter in the central nervous system. Axon diameter can vary by >100-fold, with larger axons exhibiting faster conduction velocity. Axon diameter influences myelination, can be dynamically regulated, and is altered in disease. However, gaining insights into axon diameter has been challenging due to the small size and complexity of axons in vivo. Therefore, we developed an automated high-resolution live imaging and analysis screening platform to identify pharmacological modulators of the diameter of the large Mauthner axon in zebrafish. We screened 880 compounds and identified 33 hits. Validating this pipeline, we confirmed that compounds affecting beta-2 adrenoceptor and dopamine signaling increase axon diameter. This represents the first subcellular in vivo imaging-based screen to detect changes in axon diameter, providing entry points to study the biology of this key feature of neuronal morphology.",

However, their occurrence and transformation characteristics in the urban terrestrial environment, particularly in soils of residential living regions, and their partitioning behavior in urban aquatic water-sediment systems, remain poorly understood. This study investigated the concentrations of PPDs and PPD-Qs in road dust, soil, water, and sediment samples from Shenyang, the largest city in Northeast China. The distribution characteristics of these pollutants across various functional regions and administrative districts were analyzed, along with their migration, transformation dynamics, and potential environmental risks. The results revealed widespread detection of all PPDs and PPD-Qs, with the highest concentrations in road dust from parking lots (medians: 275 and 310\u202fng/g), urban tunnel roads (238 and 192\u202fng/g), and highway toll gates (122 and 162\u202fng/g). Pollutants can migrate vertically and cross-media, with concentrations in deep soil generally lower than in topsoil. Source-indicative PPDs and PPD-Qs were identified across different terrestrial functional regions, and total organic carbon and transition metals (e.g., Fe, Cu) were influence factors of PPDs transformation. In the sediment-water system, the partitioning coefficients of PPDs (570.02-8.75\u202f\u00d7104 L/kg) were higher than those of PPD-Qs (43.10-1.85\u202f\u00d7104 L/kg), with concentrations influenced by surrounding road dust contamination. Human exposure assessment suggests that children face higher exposure potential risk due to dust ingestion, inhalation, and dermal contact. These findings offer crucial insights into the environmental fate and risk management of PPD-related emerging contaminants.",

Using the PubMed database in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, relevant studies addressing genetic and/or environmental determinants of sCS in paediatric patients were systematically reviewed. A total of 1238 records were identified, of which 97 studies met inclusion criteria after full-text review. Overall, 25,877 patients were included, with 11,086 diagnosed with sCS (42.8%). Germline genetic variants potentially associated with craniosynostosis were reported in 251 patients, accounting for 12.6% of genetically tested individuals with sCS. Identified variants were distributed across 125 genes, with recurrent findings in 25 genes. Environmental and perinatal factors were more consistently reported across large population-based and case-control studies. Frequently associated factors included male sex, advanced maternal age, maternal smoking, thyroid dysfunction, fertility treatments, foetal constraint, prematurity, and abnormal birth weight, although effect sizes varied across studies. Identifiable germline genetic causes appear to account for only a minority of sCS cases, whereas epidemiological evidence suggests that environmental and perinatal influences may also contribute to disease pathogenesis. Nevertheless, most cases lack identifiable germline mutations in key signalling pathways, and the available evidence does not support either genetic or environmental factors as individually deterministic drivers of disease development. Overall, the evidence synthesized in this review supports a multifactorial model for sCS, in which rare genetic susceptibility and non-genetic influences likely interact in the etiopathogenesis of the condition rather than reflecting a single dominant aetiology. However, heterogeneity across studies, differences in genetic testing methodologies, potential bias in exposure assessment, and the limited availability of integrative analyses restrict definitive conclusions regarding the relative contribution of these factors.",

This study characterized Mn transfer from a mine-influenced, recently disturbed upland to irrigation water, stream sediment, paddy soils, rice tissues, and screening-level dietary exposure in a semi-enclosed catchment in Ilgwang, Busan, South Korea. Surface water and stream sediment were monitored over four agricultural periods in 2021, and paddy soils and rice were sampled from four sequential irrigation zones (P1-P4). Mn was measured by ICP-OES, and solid-phase partitioning was assessed by the modified BCR sequential extraction procedure. Dissolved Mn was strongly enriched along the disturbed-upland drainage pathway (main-flow mean 4.55\u2009\u00b1\u20091.61\u00a0mg/L) relative to tributary inputs (0.16\u2009\u00b1\u20090.27\u00a0mg/L). Stream sediments approached 20,000\u00a0mg/kg with more than 97% in non-residual fractions, and paddy soils were enriched up to a field-mean of approximately 1,050\u00a0mg/kg (67-83% non-residual). A screening-level, dissolved-Mn flux analysis indicated that the upper paddy zone retained 49.5-56.6% of the seasonal irrigation-derived Mn within the soil-sediment system. Rice grain Mn ranged from 90.64 to 171.47\u00a0mg/kg (highest at P3), greatly exceeding typical background levels (1-10\u00a0mg/kg). Screening-level hazard quotients exceeded 1 in all zones and remained above 1 for young children even under a conservative 70% bioaccessibility reduction. Because the source was predominantly geogenic and bioaccessibility, cultivar, redox, and pre-disturbance baselines were not directly quantified, these results document an irrigation-mediated exposure pathway rather than a proven causal effect of land disturbance.",

We conducted a scoping review to map the existing literature regarding the aetiological mechanisms linking MS and comorbidities. We searched PubMed from inception to March, 2025, including studies of adult participants diagnosed with MS that focused on comorbidity aetiology. Studies estimating the risk or prevalence of comorbidities without investigating aetiology were excluded. For each study, we classified the proposed aetiological mechanism separately for Mendelian randomization (MR) and non-MR studies using an existing mechanistic framework. The categories were: chance/artifactual, causative, resultant, shared risk factors, and bidirectional effects. We identified, 7224 articles, of which 311 underwent full-text review; 141 underwent data extraction. The most common comorbidities were depression (n\u202f=\u202f20 studies), diabetes (n\u202f=\u202f9), and epilepsy (n\u202f=\u202f8). MR was a common study design (n\u202f=\u202f57, 40.4%). MR studies were classified as chance/artifactual (n\u202f=\u202f26), causative (comorbidity was proposed to cause MS) (n\u202f=\u202f9), resultant (MS or its treatment were proposed to cause the comorbidity) (n\u202f=\u202f20); or bidirectional (n\u202f=\u202f2). Non-MR studies were classified as: resultant (comorbidity was proposed to result from MS or its treatment) (n\u202f=\u202f19), shared risk factors (n\u202f=\u202f44), or association only (temporality could not be established) (n\u202f=\u202f21). Evidence suggests MS comorbidities arise from shared risk factors or from MS pathology or its treatment, with few demonstrating clear causal relationships.

However, traditional sample pretreatment methods are often time-consuming, labor-intensive, and rely heavily on large volumes of toxic organic solvents. In this study, an innovative in situ deep eutectic solvent (DES)-based liquid-liquid microextraction (LLME) method was developed for the preconcentration of NEOs. Conductor-like Screening Model for Real Solvents (COSMO-RS) was employed to screen suitable hydrogen bond donors as extractants. The extraction mechanism relies on stable hydrogen bonding interactions between the target analytes (acting as hydrogen bond acceptors) and the hydrogen bond donor, hexyl 4-hydroxybenzoate. The optimized LLME procedure employs 10 mL aqueous sample, 150 mg hexyl 4-hydroxybenzoate, and 120 s vortex mixing. Compared with conventional extraction method, this approach significantly reduces sample volume to 10 mL, eliminates volatile organic solvents, simplifies the workflow, and completes sample preparation in < 20 min. In combination with high-performance liquid chromatography (HPLC), the proposed method enables sensitive simultaneous determination of six NEOs, with limits of detection (LODs) ranging from 0.390 to 3.165 \u03bcg/L, recoveries of 81.61-123.04%, and relative standard deviations precision of 2.32-16.13%.

To enhance the consistent and effective evaluation of plastic additive uses, the European Centre for Ecotoxicology and Toxicology of Chemicals (ECETOC) is proposing a framework for risk assessment of plastic additives in complex scenarios. Here, the fundamental elements of the framework are presented, including an overview of available databases, tools and methodologies that enable the safety assessment of individual additives in plastic. The framework is comprised of five modules to identify and efficiently gather pertinent information. Data needs are tailored to the specific plastic additive and/or its major known transformation product(s) and to the scope of the risk assessment. As a risk-based approach, the five modules are pursued in an iterative, 'circular' manner. The risk assessment is terminated as soon as it is possible to either exclude risk potential or to characterise and manage any identified risks. While the framework for plastic additive risk assessment, as presented here, is applicable to individual plastic additives and/or their major known transformation products, it can be supplemented by further considerations for the assessment of aggregate or cumulative exposures and complex material cycles. Building thereupon, the second article by ECETOC shall present such further elements to consider when applying the framework for risk assessment of plastic additives at diverse recycling stages.",

Infants and young children may experience distinct exposure patterns due to mouthing behavior, yet oral exposure from textile-based products such as stuffed toys remains poorly characterized. This study aimed to quantify saliva-mediated PFAS migration from commercially available stuffed toys under mouthing-relevant conditions, assess the potential contribution to early-life exposure, and evaluate the effectiveness of washing as a mitigation measure. Eighteen stuffed toys intended for infants and toddlers were analysed. PFAS migration was assessed using artificial saliva under standardized conditions and quantified by Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS). Deterministic exposure assessment was performed to estimate daily and weekly intake, complemented by margin of exposure (MOE) calculations and reverse dosimetry based on biomonitoring data. The effect of a standardized water-rinsing step on PFAS migration was also investigated. PFAS were detected in all toys, with migration profiles dominated by short-chain perfluoroalkyl carboxylic acids, particularly perfluorohexanoic acid (PFHxA). A limited number of toys accounted for most of the PFAS released. Estimated intakes for EFSA-regulated PFAS (perfluorooctanesulfonic acid (PFOS), perfluorooctanoic acid (PFOA), perfluorohexanesulfonic acid (PFHxS), perfluorononanoic acid (PFNA)) remained below the tolerable weekly intake (TWI), whereas MOE and reverse-dosimetry analyses highlighted compound- and product-specific exposure relevance for short-chain and emerging PFAS. Washing reduced PFAS migration in most cases but increased migration for some PFAS and products, indicating heterogeneous and non-systematic effects. This study demonstrates that stuffed toys represent a relevant and often underappreciated source of early-life PFAS exposure. PFAS migration was observed across all products and was dominated by short-chain compounds, with perfluorohexanoic acid (PFHxA) emerging as the main driver of exposure relevance. While intake of EFSA-regulated PFAS remained below guidance values, PFHxA showed a large influence on exposure metrics, including reduced MOE and high relative contributions in reverse-dosimetry analyses. These findings reveal an important regulatory and knowledge gap for emerging PFAS and highlight the need to integrate mouthing-relevant exposure pathways into risk assessment of products intended for young children.",

This study aimed to evaluate the in vitro probiotic potential of Zymomonas mobilis UFPEDA 363. The strain exhibited exponential growth, reaching 8.8 log CFU/mL within 24 h, and demonstrated strong acid tolerance with survival rates of 54% at pH 3.0, 99% at pH 3.5, and 100% at pH 7. It exhibited notable surface properties, including auto-aggregation (64%), co-aggregation with Staphylococcus aureus and high hydrophobicity in the presence of organic solvents. The strain also tolerated bile salts, maintaining 96-100% survival and viability above log 8 CFU/mL under simulated gastrointestinal conditions. Antagonistic activity assays revealed effective inhibition of Salmonella enteritidis and Escherichia coli. Regarding safety, the strain was susceptible to most clinically relevant antibiotics, such as tetracycline and ampicillin, and it did not exhibit hemolytic or gelatinase activity. These results indicate the acid and bile salt resistance, antimicrobial potential and safety profile of Zymomonas mobilis UFPEDA 363, supporting its candidacy as a probiotic microorganism. Further in vivo studies are needed to confirm its efficacy and explore applications in functional foods or therapeutic formulations aimed at promoting human health.",

We conducted a two-sample MR study to investigate the causal association between genetically predicted serum 25-hydroxyvitamin D (25(OH)D) levels and the risk of HNC and its major subtypes: oral cavity, laryngeal, hypopharyngeal, and HPV-negative oropharyngeal cancers. Genetic instruments were selected from GWAS of 441,291 individuals (UK Biobank). Cancer outcomes were obtained from the HEADSpAcE consortium. Multiple sclerosis (MS) was analyzed as a positive control. We identified 115 independent genetic instruments for serum 25(OH)D. Causal estimates were primarily derived using inverse variance weighted (IVW) MR, supported by MR-Egger, weighted median, and mode-based methods. Extensive sensitivity analyses assessed heterogeneity, pleiotropy, and directionality. We identified 115 independent genetic instruments for serum 25(OH)D levels, which explained 5.12% of the total phenotypic variance. The mean F-statistic was 198.3 and satisfied MR assumptions. Only 17 of 682 (2.5%) SNP-confounder associations reached nominal significance (p \u2009<\u20095\u2009\u00d7\u200910\u207b8), and none remained significant after Bonferroni correction, indicating no systematic confounding. Higher 25(OH)D levels were associated with a reduced risk of MS (IVW OR\u2009=\u20090.84, 95% CI 0.71-0.99, p\u2009=\u20090.038; weighted median OR\u2009=\u20090.82, 95% CI 0.70-0.96, p \u2009=\u20090.015), while no evidence of a causal association was observed between 25(OH)D and risk of HNC or any subtype (all IVW p \u2009>\u20090.05; ORs ranging from 0.95 to 1.25). Sensitivity analyses revealed no evidence of horizontal pleiotropy, influential outliers, or reverse causation for any cancer outcome. This study provides robust genetic evidence that circulating 25(OH)D levels are not a major causal determinant of HNC risk and that our instruments are not confounded by major lifestyle or UV-related factors.",

Although many reviews summarize environmental occurrence and ecological impacts, fewer integrate human exposure pathways with mechanistic toxicological evidence and safety-relevant uncertainties. This review synthesizes evidence on inhalation, ingestion, and dermal exposure, emphasizing particle size, barrier interactions, translocation, and distribution. We examine experimental and clinical evidence describing oxidative stress, inflammatory signaling, epithelial barrier dysfunction, gut dysbiosis, immune activation, and endocrine interference associated with MP and NP exposure. Particular attention is given to distinguishing MPs from NPs in terms of cellular uptake, biodistribution, analytical detectability, and toxicodynamic behavior. We also discuss limitations in exposure assessment, including contamination bias, analytical detection limits, and harmonized reporting standards. Rather than focusing on environmental prevalence, this review highlights gaps in exposure quantification, dose-response relationships, chronic low-dose exposure, vulnerable populations, and co-exposure to plastic additives or adsorbed contaminants. An organ-specific risk perspective is integrated, emphasizing respiratory, digestive, immune, and systemic effects, as well as particle size, polymer type, exposure concentration, and human dose-response uncertainty. By synthesizing toxicological, analytical, and public health evidence, this review defines research priorities for risk assessment.",

In a prospective birth cohort in China (PKUBC-T), we identified distinct growth trajectories from birth to age 3 years using K-means clustering for longitudinal data (N = 1467) and measured 16 plasma PAHs in first-trimester maternal samples (N = 333). Twenty maternal single nucleotide polymorphisms (SNPs) related to PAHs metabolism were genotyped. Modified Poisson and weighted quantile sum regression showed that higher prenatal PAHs exposure was associated with increased risk of rapid higher growth trajectory, with phenanthrene, pyrene, and fluoranthene contributing most. This trajectory is characterized by a marginally higher BMI Z-score at birth, followed by rapid growth during infancy and sustained high levels thereafter. Furthermore, the AHR rs2066853 variant significantly modified the association, with the positive association being observed only among mothers carrying GA/AA genotypes (RR, 2.44; 95% CI, 1.51-3.97) but not among those with GG homozygotes (P for interaction is 0.049). We provide evidence that prenatal PAHs exposure may alter early childhood growth patterns, with effects modified by maternal genetic susceptibility. If confirmed, these findings highlight the mechanistic importance of AHR signaling in environmental developmental toxicity and underscore the need for exposure reduction and targeted maternal monitoring.",
        "42504319": "ID: 42504319\nTitle: Neurodegeneration in Parkinson's Disease: The Role of Environmental Toxins.\nAbstract: Parkinson's disease (PD) is a rapidly growing global health challenge, with prevalence projected to reach 13-14 million cases by 2040. While aging and improved diagnostic awareness partly explain this trend, mounting evidence implicates environmental factors as critical contributors. This review synthesizes current literature on exposures such as pesticides, solvents, heavy metals, air pollutants, and infectious agents, emphasizing their mechanistic links to neurodegeneration. These factors interact with genetic susceptibility and aging, supporting the \"multiple-hit\" hypothesis, which posits that PD arises from cumulative insults rather than a single cause. Mitochondrial dysfunction, oxidative stress, neuroinflammation, and impaired protein clearance emerge as convergent pathways underlying dopaminergic vulnerability. Recent findings highlight viral infections-particularly SARS-CoV-2-as potential triggers or amplifiers of PD pathogenesis, raising concerns about long-term neurological sequelae following pandemics. Beyond individual toxins, the exposome concept underscores the lifelong interplay of physical, chemical, and social exposures in shaping disease risk. Climate-related changes, including increased air pollution and wildfire frequency, further compound these risks, suggesting a systemic dimension to PD etiology. Understanding these complex interactions is essential for developing preventive strategies, refining experimental models, and informing public health policies aimed at mitigating environmental contributions to neurodegeneration. This multifactorial perspective offers a foundation for future research targeting modifiable risk factors and resilience mechanisms in PD. Parkinson\u2019s disease (PD) is a brain disorder that affects movement and is becoming more common worldwide. While aging and genetics play a role, research shows that environmental factors\u2014such as pesticides, air pollution, industrial chemicals, and even certain infections\u2014may also increase the risk of developing PD. This article explains how these factors can damage brain cells over time. For example, pesticides and solvents can harm the parts of the brain that control movement. Air pollution and heavy metals may also contribute to brain inflammation and stress. Infections like influenza and COVID-19 could act as \u201ctriggers,\u201d making the brain more vulnerable to damage later in life. Scientists call this the \u201cmultiple-hit\u201d theory, meaning PD often results from a combination of aging, genes, and environmental exposures rather than a single cause. The review also introduces the concept of the \u201cexposome,\u201d which looks at all the things we are exposed to throughout life\u2014chemicals, air quality, diet, and even stress\u2014and how they interact with our biology. Understanding these links can help researchers find ways to prevent PD, improve treatments, and guide public health policies. In short, Parkinson\u2019s disease is not just about getting older or having certain genes. It may also be influenced by what we breathe, eat, and encounter in our environment. By studying these factors, we can work toward reducing risks and protecting brain health.",

Moreover, current Italian treatment algorithms suggest that cannabis-based therapies may have further relevance in the management of MS. The aim of our systematic review and meta-analysis was to assess the effectiveness of nabiximols in relieving symptoms other than spasticity in adult MS patients. Methods: A systematic search was conducted in Web of Science, MEDLINE (via PubMed), Cochrane CENTRAL and Embase on September 10, 2025. Study selection was performed according to the predefined PROSPERO protocol (CRD42022329952). Data were combined into a common denominator and examined using a random-effects model with meta-regression expressed as mean difference (MD) and a 95% confidence interval (CI). Risk of bias was assessed using the Cochrane risk of bias instrument (RoB2) and the Risk Of Bias In Non-randomized Studies of Interventions (ROBINS-I) tool. Results: Of the 49 eligible articles, 25 were included in the statistical analysis (2949 patients). Significant improvements in spasm quality (MD = -16.87; 95% CI = (-29.75)-(-3.99)), bladder function (MD = -16.38; 95% CI = (-22.18)-(-10.58)), sleep disruption (MD = -15.75; 95% CI = (-22.02)-(-9.49)) and gait function (timed walk MD(s) = -5.31; 95% CI(s) = (-9.88)-(-0.74)) were observed. Time-dependency was not significant. The subject global impression of change (SGIC) improved significantly after the first month (odds ratio (OR) = 1.69; 95% CI = (1.30)-(2.18)). Conclusion: Beyond spasticity, nabiximols may represent a signal of benefit for bladder function, sleep disruption, spasm quality, and gait function in MS, in line with the \"spasticity-plus\" concept. However, the evidence certainty was low to very low, and these findings should be considered exploratory.",

Among these hazards, mycotoxins represent one of the most significant and widely investigated contaminants in food and feed. This review aims to summarize current knowledge on mycotoxin risk assessment practice, both for single substances and for cumulative risk assessment, and to provide practical guidance for future researchers. As individual substances, mycotoxins are well characterized from a toxicological perspective, and numerous risk assessments have been conducted globally across a wide range of food products. Although well-established methodological frameworks exist to support the cumulative risk assessment of mycotoxins, further efforts are needed to define common assessment groups, especially considering the pleiotropic nature of these compounds.",
        "42507732": "ID: 42507732\nTitle: Selective GPR17 antagonism enhances structural and functional recovery in animal models of demyelination.\nAbstract: Myelination, driven by differentiation of oligodendrocyte precursor cells, is critical for metabolic and structural support and efficient axonal signal transmission in neurons. Loss of myelin is a hallmark of multiple sclerosis and other devastating demyelinating disorders. As demyelination persists, neurons become increasingly vulnerable, leading to neurodegeneration and chronic disability. Restoring myelin through endogenous repair mechanisms offers a promising therapeutic approach to mitigate progressive neuronal loss. One key regulator of myelination is the G protein-coupled receptor 17, GPR17, whose chronic upregulation in oligodendrocyte precursor cells is commonly seen with myelin injury. In line with single-nucleus transcriptomic data showing predominant expression of GPR17 in committed oligodendrocyte precursor cells, our postmortem immunohistochemical analyses of MS patient tissue revealed a significant upregulation of GPR17+/BCAS1+ oligodendrocyte precursor cells adjacent to and in demyelinated lesions. Importantly, remyelinated lesions lacked GPR17 immunoreactivity, consistent with a model in which sustained GPR17 expression is associated with demyelination and impaired oligodendrocyte precursor cell differentiation. To test the impact of pharmacological GPR17 inhibition on remyelination, we evaluated the effects of a novel, selective GPR17 antagonist in cuprizone-induced murine demyelination models. This toxin-induced approach has been widely used to study mechanisms of de- and remyelination, in the absence of the full inflammatory complexity of demyelinating diseases such as multiple sclerosis. We show that oral treatment results in robust functional recovery consistent with remyelination, as evidenced by improved spatial memory and recovery of visual evoked potential latency delays. GPR17 antagonism also accelerated structural remyelination in the corpus callosum and optic nerve. Together, these findings support a role for pharmacological GPR17 antagonism in promoting remyelination and highlight this G protein-coupled receptor as a promising therapeutic target for demyelinating disorders.",

This study developed a rapid, highly sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) method applicable to all regulated food categories. The method's high sensitivity is essential, as it improves dietary exposure assessment and reduces uncertainties in risk evaluation, particularly for vulnerable populations. The method was validated with satisfactory recoveries (71-109%). A total of 115 food samples were analysed, including 28 infant food samples, a category notably underrepresented in European datasets. Perchlorate was detected in 95.7% of samples, with concentrations exceeding the European Union (EU) maximum limit in four cases. Risk assessment showed that infants and toddlers are especially vulnerable, with a Hazard Index, exceeding the safe limit of 1.",

Mouse models remain essential for dissecting these mechanisms, but no single model fully reproduces the heterogeneity, chronicity, and immune complexity of autoimmune disease in humans. This review summarizes classical murine and humanized mouse models used to study inflammatory bowel disease (IBD), multiple sclerosis (MS), type-1 diabetes (T1D), and rheumatoid arthritis (RA). We also highlight disease-specific scoring systems, including clinical indices, histopathology, imaging, cytokine profiling, autoantibody assessment, and human immune-cell readouts, as essential tools for standardized interpretation. Conventional murine models provide experimental control and mechanistic clarity, whereas humanized models improve assessment of human immune responses, patient-specific biology, and therapeutic translation. However, humanized systems remain limited by incomplete immune reconstitution, graft-versus-host disease, donor variability, cost, and incomplete tissue architecture. By providing a comparative framework spanning both conventional and humanized models, this review aims to guide informed model selection tailored to specific research questions in autoimmune disease biology and translational therapeutic development.",

Aquatic foods are important components of dietary diversification, but their association with internal PFAS burden remains unclear in inland populations. Of the 1294 participants initially recruited, 1292 with complete demographic information were included in the final analyses. Serum concentrations of 22 PFASs were measured by solid-phase extraction coupled with UPLC-MS/MS, and nine PFASs detected in more than 75% of samples were analyzed. Dietary intake frequency, sociodemographic characteristics, and lifestyle factors were collected using structured questionnaires. Multivariable linear regression and sex-stratified analyses were performed. Seafood-related food groups showed the most consistent positive associations with serum PFAS levels. Frequent consumption of shellfish, shrimp, crabs, fish, and seaweed was associated with higher concentrations of long-chain PFASs, including PFDA, PFNA, PFHxS, PFOS, and PFOA, while shrimp and crab intake was also positively associated with 6:2 Cl-PFESA. These associations were generally stronger in males, suggesting sex-related heterogeneity in the relationship between seafood intake and PFAS body burden. These findings suggest that seafood consumption is associated with distinct PFAS body-burden profiles in inland adults and may support integrated biomonitoring, dietary assessment, and food-contaminant surveillance.",

Vitamin C, due to its antioxidant and neuroprotective properties, has been hypothesized to reduce MS risk, but epidemiological evidence remains inconsistent. We conducted a prospective cohort study using UK Biobank data, including 486,908 adults aged 37-70 years free of neurological disease. Regular vitamin C supplementation was self-reported at recruitment. Incident MS cases were identified during a median follow-up of 13.5 years. Propensity score weighting was used to balance a wide range of demographic, lifestyle, and health-related confounders. Weighted Cox proportional hazards models were used to estimate hazard ratios (HRs). Effect modification by polygenic risk score (PRS) for MS was assessed, and multiple sensitivity analyses were performed. During follow-up, 452 participants were diagnosed with MS. Vitamin C supplementation was reported by 8.8% of participants (missingness = 1.5%) and was associated with a lower risk of incident MS (HR = 0.51, [95%CI: 0.32; 0.82], p = 0.004). The estimate was consistent across multiple sensitivity analyses. The association varied according to genetic susceptibility, with significant nonlinear multiplicative interaction (p = 0.004) and additive interaction (p < 0.001). Specifically, significant associations were observed only among those with average or high MS-PRS. Vitamin C supplementation was associated with a lower risk of incident MS, with the association varying across levels of genetic susceptibility. Although residual confounding cannot be excluded, sensitivity analyses did not identify similar associations for overall supplement use or multivitamin use, providing some reassurance against a generalized healthy-user effect. Replication in independent cohorts is warranted.",

This pilot study integrated paired biomarkers, local foods, work and indoor dust, Hg speciation and hair Hg isotope signatures among 18 e-waste dismantling workers in Qingyuan, South China. Total Hg (THg), MeHg and inorganic Hg (IHg) were measured in hair, blood and foods; urine and dust were analyzed for THg; and hair \u03b4202Hg, \u0394199Hg and \u0394201Hg were determined. Median THg was 403 \u03bcg/kg in hair, 1.60 \u03bcg/L in blood and 0.438 \u03bcg/L in urine. Fish showed the highest food THg, whereas work and indoor dust had the highest matrix concentrations. Hair was MeHg-dominant but contained substantial IHg, and \u0394199Hg values were positive but modest. The integrated patterns support mixed dietary MeHg and non-dietary IHg contributions and identify exposure-pathway priorities for future biomonitoring and source-focused studies.",

However, the occurrence patterns, source characteristics, and exposure implications of emerging OPE congeners across diverse urban indoor microenvironments remain inadequately elucidated. In this study, twenty-eight OPE congeners were quantified in settled dust collected from eight representative indoor microenvironments and one outdoor reference site in Beijing, China. Total OPE concentrations exhibited pronounced spatial heterogeneity, ranging from 8.46 to 42.60 mg kg-1, with the highest levels observed in subway stations and laboratories. Non-halogenated OPEs dominated the contamination profile, accounting for 80.7% of the total OPEs, whereas Tris(2-ethylhexyl) phosphate (TEHP), 2-Ethylhexyl diphenyl phosphate (EHDPP), Tris(1-chloro-2-propyl) phosphate (TCIPP), Tris(2-chloroethyl) phosphate (TCEP), and Triphenyl phosphate (TPhP) collectively contributed 85.1% of the overall burden. Correlation analysis and positive matrix factorization revealed that indoor OPE contamination was primarily associated with emissions from building materials, polymer-containing consumer products, furniture, and electronic equipment. Transformation-associated compounds such as Bis(2-butoxyethyl) hydroxyethyl phosphate (BBOEHEP) were detected in indoor dust, pointing to the plausible presence of OPE transformation processes in such enclosed settings. Exposure assessment demonstrated that dust ingestion accounted for over 98% of total OPE intake, resulting in substantially higher exposure levels in children than in adults. Although estimated non-carcinogenic and carcinogenic risks remained below established health-based thresholds, exposure was disproportionately driven by a limited number of congeners, particularly EHDPP, TCIPP, TCEP, and TEHP. These findings highlight the growing contribution of replacement OPEs to indoor chemical burdens and underscore the importance of incorporating transformation products and indoor aging processes into future exposure and risk assessments frameworks.",

Within the submitted application the applicant requested as well to modify the existing maximum residue level (MRL) for folpet in honey. The data submitted in support of the requests were found to be sufficient to derive an MRL proposal for bananas according to the current residue definition for enforcement. For honey however, the submitted trials were not compliant with good agricultural practice (GAP) and therefore not appropriate to derive an MRL proposal. Adequate analytical methods for enforcement, based on liquid and gas chromatography, are available to quantify residues of folpet and phthalimide in bananas and honey with lowest validated limit of quantification (LOQ) of 0.01 mg/kg (both compounds). Based on the risk assessment results, EFSA concluded that the short-term and long-term intake of folpet residues expected in bananas and honey is unlikely to present a risk to consumer health. However, uncertainties remain regarding the long-term exposure assessment due to missing residue data for phthalamic acid (in root crops) and phthalic acid (in all commodities except bananas and honey).",

AMPA recognize post-translationally modified proteins and are cross-reactive. AMPA include anti-citrullinated protein antibodies (ACPA), anti-carbamylated protein antibodies (anti-CarP), and anti-acetylated protein antibodies (AAPA). These autoantibodies can be detected years before disease onset and are associated with disease development and progression. Moreover, AMPA have been associated with genetic and environmental risk factors in RA, including human leukocyte antigen (HLA) alleles, smoking, and microbial exposure. Consequently, AMPA have been implicated in RA pathogenesis, yet their exact role remains unclear. ACPA may exert pathogenic, pro-inflammatory effects through immune complex formation, Fc gamma receptor binding on macrophages, complement activation, and increased neutrophil extracellular trap (NET) formation. Additionally, ACPA have been linked to bone loss and pain induction in mice. However, ACPA may also have protective effects through inhibition of NET release, increased NET clearance, and Fc gamma receptor binding on macrophages. These findings indicate that AMPA may have diverse functions in RA, with both pathogenic and protective effects, whereas some ACPA may not display functional activity. Further studies on AMPA characteristics and mechanisms underlying the pathogenic and protective effects may improve the understanding of the role of AMPA in RA.",

This study aimed to pool the prevalence and concentration of antimicrobial and pesticide residues in Bangladeshi ASFs and to estimate dietary exposure and risk using deterministic and probabilistic frameworks benchmarked against health-based guidance values. Following PRISMA 2020, five databases were searched from January 2010 to April 2026. Random-effects models (Freeman-Tukey transformation, DerSimonian-Laird estimator) pooled prevalence across five matrices. Estimated daily intakes were combined with national consumption data and JECFA/JMPR acceptable daily intakes (ADIs) to derive hazard quotients (HQs), a cumulative hazard index (HI) and margins of exposure (MOE); a 10,000-iteration Monte-Carlo simulation characterized high-consumer (P95) exposure. Thirty-five studies (5,255 samples) were analyzed. Pooled prevalence was 12.9% (95% CI 8.8-17.6; I2\u00a0=\u00a095.8%), highest in farmed fish (40.3%) and lowest in eggs (4.7%); tetracyclines, fluoroquinolones, and organochlorines predominated. For the average adult, all HQs were \u226a1 and the cumulative HI was 0.031; heptachlor and dieldrin dominated (P95 %ADI 6.2 and 4.7). The child HI (\u22480.062) remained below unity; chloramphenicol P95 MOE fell to 253. Central-tendency dietary risk is low, but high-consumer tails, cumulative exposure, prohibited-substance detection and small-study effects justify strengthened, Codex-aligned residue surveillance, withdrawal-period enforcement and risk-based national monitoring within a One-Health framework.",

Therefore, we present a size-resolved framework that couples saliva-specific evaporation and residue formation with gravitational settling to compute airborne viral RNA covering 1-2000 \u00b5m under varied temperature, relative humidity, and ambient pressure (101.325 and 75.3\u00a0kPa). Our framework also combines particle volume contribution considering saliva mass uncertainty, viral load, viral half-life, exhalation mechanisms (talking, coughing, sneezing), and ventilation effects. Under literature-based half-life inputs and volume-proportional RNA allocation, viral load and size-resolved airborne lifetime dominated the simulated RNA-copy trends, although the role of viral half-life may vary if RNA decay differs from infectivity decay or if viral RNA concentrates in long-suspended fine aerosols. Talking dominates persistence of airborne RNA copies since coughing and sneezing produce larger droplets that settle quickly. Also, model predictions are compared with hospital air-sampling datasets. The 50-percentile of saliva mass provides the closest match, with most samples falling within roughly one order of magnitude and central tendency close to unbiased. Our model is designed to serve as (1) pre-processor that supplies inputs for infection-risk assessment modeling studies and (2) decision-making support tool, facilitating public-health intervention. Therefore, we also provide an online web tool that allows users to directly adjust inputs and immediately analyze scenario-specific outcomes.",

Here, we compared demyelination induced by the administration of 0.3% CPZ mixed with ground rodent chow and a 400 mg/kg CPZ suspension in carboxymethyl cellulose (CMC) via oral gavage in SWR/J mice. The mice were assigned into a control group, a CPZ diet group, and an oral CPZ groups (n = 6 mice/group). Rotarod, hanging wire, and open field tests were performed to evaluate locomotor activity. Histological analyses were conducted on the corpus callosum (CC) of the brain to determine myelin loss and on the liver to assess the toxicity of CPZ. The administration of CPZ with ground rodent chow significantly reduced body weight gains, grip strength, and motor coordination performance during the 5-week demyelination period. In contrast, all analyzed parameters were less different in mice receiving CPZ via oral gavage. However, both CPZ routes significantly reduced myelin content in the CC. Additionally, the oral administration of CPZ had strong effects on liver toxicity compared to that of CPZ diet feeding. This study showed that both routes of CPZ intoxication could induce reproducible and consistent demyelination changes within the CC of the mouse brain, with the CPZ diet being more effective based on all analytical parameters and having fewer toxic effects on the liver compared with oral CPZ. In conclusion, the resultsassist in the selection of a suitable multiple sclerosis (MS) model for investigating disease mechanisms and therapies.",

We examined four SDH (education, work, financial resources and social life) to study the impact of MS and explore interrelationships, identify risk factors, and study the association with social support. SocialMS is a cross-sectional Italian questionnaire-based study including adults with MS. The number of SDH affected by MS was the primary endpoint and risk factors were identified using Poisson regression. We included 1039 participants (mean age: 43.82 years (sd: 11.53); 68.82% females; 86.53% relapsing remitting; median Patient Determined Disease Steps (PDDS): 1 (iqr: 0-3)). Median number of SDH affected by MS was 1 (iqr: 0-3), with social life (51.20%) and work (48.22%) most impacted; high interrelationships among domains were observed. Relevant risk factors included socioeconomic factors (education incomplete at diagnosis: incidence-rate ratio (IRR)=1.19 [95% CI: 1.06; 1.35]; non-working or early retired: IRR=1.18 [1.05; 1.34]; economic strain: IRR=1.47, [1.31; 1.64]), comorbidities (IRR=1.23 [1.11; 1.37]) and PDDS (IRR=1.17 [1.13; 1.20]). Almost 90% received tangible (64.29%) or intangible (85.18%) social support, and number of SDH impacted by MS was positively associated with both (p\u202f<\u202f0.05).

Epidemiological evidence mainly comes from incidence studies, whereas cause-specific mortality, reflecting disease occurrence and survival, has rarely been examined.Estimated associations may depend on the scale of ALAN exposure assessment, including grid-level and buffer-based measures. We aimed to (1) assess the associations between long-term ALAN exposure and natural-cause and cause-specific mortality; (2) evaluate the sensitivity of these associations across various spatial scales of the ALAN assessment; and (3) examine whether some socio-demographic population groups are more vulnerable. We conducted a register-based cohort study of 6,325,139 adults in the Netherlands (2013-2023). We linked satellite-derived average ALAN exposure over 2013-2023 to residential addresses using 50-m grid values and 300-1,000\u00a0m buffers. Mortality included natural causes, cerebrovascular disease (CeVD), coronary heart disease (CHD), type 2 diabetes (T2D), obesity, breast cancer (BC), and prostate cancer (PCa). Associations were estimated using Cox proportional hazards models adjusted for individual-level characteristics and environmental exposures, with effect modification assessed via interaction terms and stratification. ALAN exposure was positively associated with natural-cause mortality and with mortality from T2D, obesity, BC, and PCa. The most robust association was for T2D (HR\u00a0=\u00a01.06, 95% CI: 1.02-1.10) and obesity (HR\u00a0=\u00a01.07, 95% CI: 1.00-1.15). Associations for BC and PCa were positive only after adjusting for environmental exposures. No associations were found for CHD or CeVD mortality. Estimates were attenuated with larger buffers. Stronger associations were observed among middle-aged adults, those with low and middle levels of education, low-income groups, women, non-Dutch, and non-cohabiting populations. Long-term ALAN exposure was associated with metabolic-cause mortality (notably T2D), with stronger associations in some socio-demographic groups, suggesting differential vulnerability. Effect estimates varied with the spatial scale of exposure assessment and with adjustment for other environmental exposures.",

Despite differences in etiology and clinical presentation, these conditions share multifactorial pathophysiological mechanisms influenced by genetic, environmental, and lifestyle-related factors. Advances in artificial intelligence (AI), wearable technologies, and multimodal clinical data integration offer new opportunities for identifying predictive digital biomarkers and improving personalized disease management. The rAIdD project (\"eHealth Network: AI and new ICT technology equipment for digital diagnosis\") aims to develop an interoperable digital infrastructure to support early diagnosis, monitoring, and risk stratification in chronic neurological diseases. This study protocol describes the neurological component of the rAIdD network focusing on MS, PD, and AD. This prospective, multicenter, observational study involves six Italian academic and clinical centers and will enroll 780 participants: 300 MS, 150 PD, 150 AD, and 180 healthy controls. Participants will be followed for 18 months within a 48-month study period. Standardized clinical, neuropsychological, neuroimaging, and digital assessments will be performed at baseline and at 6-, 12-, and 18-month follow-ups. Clinical evaluation includes disease-specific disability and functional scales, mood and quality-of-life assessments, and lifestyle and environmental risk factor profiling. Continuous digital monitoring will be conducted using wearable sensors to collect biometric and behavioral data, including physical activity, sleep patterns, and cardiovascular parameters. Structural neuroimaging will be acquired longitudinally and integrated with clinical and digital data through a centralized web-based electronic data capture platform. Machine learning approaches will be applied to identify multimodal predictive biomarkers and model disease progression patterns across disorders. The study has been approved by the Ethics Committee of the coordinating center and by local ethics committees of all participating institutions. Written informed consent is obtained from all participants in accordance with the Declaration of Helsinki and the General Data Protection Regulation (GDPR 2016/679).

This geochemical characteristic can be transferred to the human body via food intake, thereby posing potential health risks. Conventional assessments based only on total elemental concentrations may not reflect the fraction released during gastrointestinal digestion. In this study, the Unified Bioaccessibility Method (UBM) was combined with Monte Carlo simulation to evaluate dietary As exposure and Se intake from typical Tibetan foods. The results showed a low dietary Se/As ratio of 0.80, far below the national average of 4.35. Bioaccessibility-adjusted modeling reduced estimated As exposure, but carcinogenic risk remained above 10-4 in all age groups, with the highest mean risk in children. Estimated Se intake was also below the recommended level. After simulated gastrointestinal digestion, the As-Se correlation increased from r = 0.40 to 0.58, indicating a stronger postdigestion association. These findings highlight the need to incorporate bioaccessibility into dietary exposure assessment and suggest that Tibetan populations may face both elevated As-related risk and insufficient Se intake.",

Muscle samples (musculus semimembranosus and musculus triceps brachii; n\u2009=\u200910) obtained from free-ranging individuals in Slovakia were analysed using validated analytical methods. Brown bear muscle was characterised by high protein content (~\u200922.5\u00a0g/100\u00a0g) and low intramuscular fat content (<\u20091\u00a0g/100\u00a0g), confirming its lean nutritional profile. The fatty acid composition was dominated by monounsaturated fatty acids, followed by saturated and polyunsaturated fatty acids. Lipid quality indices indicated favourable nutritional properties, including low atherogenic and thrombogenic indices and a PUFA/SFA ratio above recommended nutritional thresholds. However, the relatively high n-6/n-3 ratio reflected the omnivorous feeding ecology and seasonal physiological status of the analysed animals. Iron and zinc represented the predominant trace minerals, highlighting the nutritional value of the analysed muscle tissue. Most toxic elements (As, Cr, Cd, Hg) remained below analytical detection or quantification thresholds and were therefore interpreted descriptively. Lead (Pb) was detected at low mean concentrations; however, substantial inter-individual variability resulted in sporadically elevated values, most likely associated with secondary contamination from bullet fragments. Exposure assessment based on consumption of a 100\u00a0g portion and an upper-bound approach for left-censored data indicated negligible toxicological relevance for Cd and Hg, whereas Pb exposure increased considerably under maximum exposure scenarios. Overall, brown bear muscle represents a nutritionally valuable food source; however, continued monitoring of Pb contamination in game meat remains warranted.",

Here, we review current evidence for the involvement of EBV in MS, its impact on existing therapeutics, and strategies for novel therapeutic directions. Compelling evidence indicates EBV infection precedes MS onset, likely contributing to disease initiation, relapses, and possibly progression through mechanisms such as molecular mimicry, B cell immortalization, and viral reactivation. Current MS therapies may indirectly suppress EBV by depleting B cells or restricting lymphocyte CNS entry. Novel strategies, including CAR-T/-NK cells, adoptive T cells, \"kick and kill\" approaches, and vaccines, aim to directly target EBV and offer promising new avenues for MS therapy.",

The transmembrane glycoprotein cluster of differentiation 44 (CD44) has been implicated in neuroinflammation, but its functional role remains unclear. Here, we examined CD44 expression and function across both non-immune-mediated and immune-mediated MS animal models, including cuprizone-induced demyelination, experimental autoimmune encephalomyelitis (EAE), and combined cuprizone/EAE (Cup/EAE), as well as in human MS tissue and cerebrospinal fluid (CSF), using immunohistochemistry, flow cytometry and enzyme-linked immunosorbent assay. CD44 expression increased in parallel with demyelination and was most pronounced in the forebrain of Cup/EAE mice, where it localized to perivascular cuffs and lesion-associated parenchyma. CD44 expression co-localized to IBA1\u207a microglia/monocytes and CD3\u207a T cells. Flow cytometry analyses revealed high CD44 expression on myeloid-derived suppressor cells and regulatory T cells, which further increased upon immune activation. On the functional level, Cd44-deficient mice exhibited exacerbated disease severity in EAE, accompanied by increased immune cell infiltration and tissue damage. In human MS samples, CD44 expression and soluble CD44 levels in CSF were significantly elevated. Notably, CD44 upregulation was also observed in other neurological disease models, including ischemic stroke and APPswe/PS1dE9 mice, a model of Alzheimer's disease. Together, these findings identify CD44 as a conserved marker of neuroinflammatory activity and a context-dependent regulator of neuroinflammation with partially protective functions, rather than an exclusively pro-inflammatory molecule, highlighting its potential relevance in MS and related neurological disorders.",

The findings were based on discussions and presentations from the Fourth International Aerosol Dosimetry Conference held in 2024 in Irvine, California. The conference used plenary sessions to promote cross-disciplinary communication and collaboration. Topics included computational models and simulations, in vitro and in vivo aerosol exposure systems, and variability in inhaled aerosol deposition. State-of-the-art research was presented, followed by open discussions to identify knowledge gaps and future priorities. Significant advances were reported in computational modeling, particularly in integrating different model types to better represent all major regions of the respiratory tract. Improvements in in vitro exposure systems enhanced particle delivery, dose measurement, and applicability to human health studies. Research also highlighted the importance of the upper airways as entry routes for inhaled medications. Dose variability emerged as a critical issue across aerosol dosimetry studies. New findings showed that inhaled ultrafine particles may acquire surface coatings after deposition and can penetrate tissues, including fetal tissues. Standardization and validation of in vitro approaches were identified as essential steps for reducing reliance on animal testing and improving human risk assessment. Internal aerosol dosimetry research continues to advance through improved models, exposure systems, and mechanistic understanding of deposited particle behavior.

In part, this is because our complex food supply chains are increasingly at risk of overprocessing, contamination, low nutrient content, and economically motivated fraud. Chemical testing can offer insights into these concerns, but testing methods are frequently impractical. Extra virgin olive oil (EVOO) is a premium food of high nutritional value, but because of its growing popularity and high price, it can be a target for mislabeling, substitution, dilution, and/or false claims of origin. Rapid and accurate testing methods for its characterization are therefore increasingly important. We used two direct forms of mass spectrometry (MS)-laser desorption/ionization (LDI) MS and direct analysis in real time (DART) MS-to obtain complex chemical signatures of edible oils. The data generated on a set of reference samples were then used to develop and train three independent machine learning (ML) models that assess key characteristics of a test oil. We also developed a proof-of-concept DART-MS/MS assay add-on for the quantification of bioactive phenols in EVOO. Our approach accurately predicts several attributes of an edible oil based on novel markers and intricate patterns within the acquired data. Further, pure reference standards and an isotopically-labeled internal standard allow accurate quantification of the constituent phenols. Because there is no chromatography, both the mass fingerprints and quantification can be performed in seconds-minutes. The method uses low (milliliter) volumes of sample and green solvents, and when combined with ML, it offers rapid data analysis and comprehensive result interpretation.",

However, the poor stability of the host matrix limits their actual applications. In this study, a new class of long afterglow materials with AlPO4-5 zeolite as the host matrix and various aromatic acids (terephthalic acid, 2-naphthoic acid, and 1-pyrenecarboxylic acid) as guest molecules has been developed. The prepared composites exhibit tunable afterglow emissions across the visible spectrum from blue to green to red, with lifetimes of 919, 1540, and 74\u00a0ms and intensities approximately 42, 579, and 29 times higher than those of the corresponding pure organic molecular solid powders. Studies reveal that the efficient afterglow emission primarily stems from the effective dispersion and strong adsorption of organic molecules by the zeolite matrix, as well as the host-guest coordination interactions. Remarkably, the zeolite matrix endows the composites with excellent stability against radiation, solvents, acids, alkalis, and heat, together with potential for multimodal applications. Such a combination of properties is challenging to achieve with other matrix materials. This work establishes a novel strategy for developing long afterglow materials that integrate efficient emission, robustness, and multifunctionality.",

Herein, we address this challenge via an innovative rigid-flexible coupled polymer network, specifically synthesized by copolymerizing flexible butyl acrylate (BA) monomers with rigid triallyl isocyanurate (TAIC) crosslinkers. The rigid TAIC framework imparts exceptional mechanical integrity and electrochemical stability, while the polymerized BA matrix effectively confines solvents, enabling efficient ion-transport pathways. Moreover, the polymer network regulates the Na+ solvation environment, thereby inducing a stable, inorganic-rich solid electrolyte interphase. The rationally designed electrolyte (pBAT-1/8) achieves an ultrahigh Young's modulus of 40\u00a0MPa (125\u00a0MPa of the pBAT-1/8 skeleton) to effectively suppress dendrites, while maintaining high ionic conductivities (0.33, 1.58, and 2.11\u00a0mS cm-1 at -10, 30, and 70\u00a0\u00b0C, respectively) and a high Na+ transference number (0.51).

This narrative review synthesises evidence from cohort studies of medical radiation workers across occupational exposure eras, with emphasis on epidemiologic approaches, observed cancer risk patterns, and sex-specific differences. Epidemiologic methods have evolved from proxy-based exposure indicators to quantitative dose-response modelling using excess relative risk, supported by improved dosimetry and organ-dose reconstruction. Early high-dose cohorts consistently demonstrate elevated risks for radiosensitive cancers, including breast cancer, haematopoietic malignancies, and non-melanoma skin cancer. In contrast, contemporary cohorts exposed under current protection standards accumulate low cumulative doses and show small, often non-significant dose-response estimates with wide confidence intervals. These findings reflect both reductions in occupational exposure and the limited statistical power of epidemiologic studies at low dose levels, where excess risks are difficult to detect and dose-response shape cannot be clearly distinguished. Available evidence does not indicate consistent sex-based differences in radiation-related cancer risk at occupational exposure levels. Overall, while advances in dosimetry have improved exposure assessment, the ability to quantify cancer risk under contemporary low-dose conditions remains constrained. The findings support the effectiveness of current radiation protection practices while highlighting persistent uncertainty in estimating risks at low occupational doses.",

The comparison tested how solvent polarity and hydrogen-bonding behavior affect product distribution under otherwise fixed conditions. FTIR, GPC, and GC-MS showed differences among the five soluble fractions. Protic solvents retained more phenolic monomers and oligomers, whereas aprotic solvents gave more oxidized products and different H:G:S profiles. The ethanol fraction had the highest apparent thermal stability (Ea\u00a0=\u00a04.14\u00a0kJ/mol; DTG peak\u00a0=\u00a0380\u00a0\u00b0C) and the lowest Mw (856\u00a0Da). Methyl cellosolve produced the highest-Mw fraction (2985\u00a0Da) and a more balanced H:G:S distribution. Guaiacol accounted for 40.6% of the ethanol fraction, coumaran for 70.4% of the THF fraction, and syringol for 17.2% of the methyl cellosolve fraction. THF-only controls did not produce a peak assigned to coumaran in the relevant retention-time window, which supports a lignin-derived origin for this signal under the tested conditions. The screening results link solvent properties to lignin fragmentation and the composition of the soluble products. Solvent recycling, residue characterization, process optimization, and atom-resolved mechanistic studies remain to be completed.",

Increasing evidence suggests that oxidative stress plays a central role in COPD pathogenesis by disrupting the balance between proteolytic enzymes and their endogenous inhibitors, thereby promoting extracellular matrix degradation. Among these regulatory systems, the matrix metalloproteinase-2 (MMP-2) and tissue inhibitor of metalloproteinase-2 (TIMP-2) axis has emerged as a critical determinant of lung tissue integrity and remodeling. This review provides a comprehensive overview of the molecular mechanisms linking environmental risk factors, including cigarette smoke and particulate matter exposure, to oxidative stress-mediated activation of inflammatory signaling pathways such as nuclear factor-\u03baB (NF-\u03baB), mitogen-activated protein kinase (MAPK), and activator protein-1 (AP-1). These pathways contribute to the upregulation of MMP-2 expression and dysregulation of TIMP-2 activity, resulting in protease-antiprotease imbalance and progressive structural damage to the pulmonary extracellular matrix. In addition, the review summarizes current evidence regarding genetic polymorphisms in MMP-2 and TIMP-2 genes that may influence susceptibility to COPD and disease severity across different populations. Furthermore, emerging therapeutic strategies targeting oxidative stress and matrix remodeling pathways are discussed, highlighting their potential role in disease management. Despite advances in understanding COPD pathogenesis, significant gaps remain in elucidating the precise molecular regulation of the MMP-2/TIMP-2 axis and its clinical utility as a diagnostic or prognostic biomarker. Overall, this review emphasizes the importance of the MMP-2/TIMP-2 regulatory system as a central mechanistic link between oxidative stress and structural lung damage in COPD and underscores its potential as a promising target for future therapeutic intervention.",

The Creme RIFM Aggregate Exposure Model is a probabilistic framework that estimates aggregate consumer exposure to fragrance ingredients in cosmetics and personal care products across dermal, inhalation, and oral routes. A key feature of the model is the ability to update consumer habits and practices data while maintaining a consistent assessment methodology. Phase IV incorporates Kantar Worldpanel consumer diary data collected throughout 2023, replacing the 2014-2015 dataset. The updated database includes 37,165 participants aged 11-79 years from the United States and five European countries. Integration of the new data required refinements to product categorization, product mapping, application-site assignment, and the addition of previously unrepresented product categories. Comparison of exposure estimates from the two datasets showed that consumer use patterns remained largely consistent. Differences were mainly attributable to methodological refinements, improved product mapping, changes in regional population coverage resulting from the exclusion of Italy in the 2023 dataset, and inclusion of new product categories. Overall, the update strengthens the model's relevance, robustness, and utility for fragrance safety and exposure-based risk assessment.",

However, it remains unclear whether LOMS differs etiologically from adult-onset multiple sclerosis (AOMS). To determine whether established MS risk factors differ between LOMS and AOMS and influence age at onset. We conducted a Swedish population-based case-control study including 3950 incident MS cases and 7340 controls. Cases were classified as LOMS (n\u2009=\u2009396) or AOMS (n\u2009=\u20093554). Associations between risk factors and LOMS and AOMS were estimated using logistic regression. Case-only analyses assessed associations with age at onset. Most MS risk factors, including MS heredity, HLA-DRB1*15:01, Epstein-Barr nuclear antigen (EBNA)-1 antibody levels, smoking, and low sun exposure, were associated with both onset groups, with stronger effects in AOMS. Elevated body mass index at age 20\u2009years was associated with AOMS, while estimates in LOMS were imprecise. Case-only analyses showed no association with disease timing. Exposure distribution varied across birth cohorts, suggesting cohort effects. Established MS risk factors appear to be more clearly related to disease susceptibility than to timing of onset. The broadly consistent risk factor profiles support a shared etiology, although modest differences cannot be excluded.",

In this study, arsenic (As), selenium (Se), tin (Sn) and mercury (Hg) were quantified in surface seawater (n\u2009=\u200938) and surficial sediments (n\u2009=\u200919) across six Egyptian ports (Port Tawfiq, Zayteiat, Hurghada, Safaga, Nuweibaa and Sharm El-Sheikh). Six contamination and ecological-risk indices (CF, Igeo, PLI, MPI, Er and RI) were integrated with a USEPA-compliant human health risk assessment and multivariate source apportionment to disentangle natural and anthropogenic signatures. Dissolved As exhibited a pronounced and biogeochemically coherent seasonal inversion, with winter concentrations (8.82\u2009\u00b1\u20091.04\u00a0\u00b5g\u00a0L-1) 3.2-fold higher than summer values (2.76\u2009\u00b1\u20090.53\u00a0\u00b5g\u00a0L-1; p\u2009<\u20090.001), whereas Se followed the opposite trend (summer\u2009>\u2009winter; p\u2009<\u20090.001). All stations fell within the \"low\" ecological-risk category, with sediment-based indices uniformly low (PLI\u2009=\u20090.07-0.47; RI\u2009=\u20093.6-22.4). Critically, non-carcinogenic hazard indices for children exceeded unity at all six ports (HI\u2009=\u20091.13-1.57), driven predominantly (>\u200992%) by As, an exceedance that would be masked by adult-only assessment (HI\u2009=\u20090.50-0.67). Total carcinogenic risk remained within the acceptable 10-6-10-4 range. Principal component analysis and inter-element correlations (r\u2009\u2265\u20090.84, p\u2009<\u20090.001) resolved two anthropogenic clusters: a legacy antifouling-paint (Sn-As-Hg) signature at high-traffic ports persisting over a decade after the 2008 IMO organotin ban, and petroleum-related Se enrichment at the Zayteiat oil terminal. These findings highlight the necessity of age-stratified exposure assessment and sustained multi-compartment monitoring as Suez Canal traffic intensifies.",

Extractable and leachable (E&L) studies are crucial for identifying the chemicals that migrate to the e-liquids from the components and containers housing the e-liquids during storage and inform the potential ENDS risks to public health. There are few published ENDS E&L studies that provide limited information regarding the components and e-liquid containers. Thus, this study includes extractable testing followed by leachable testing that are designed to comprehensively examine and determine the chemicals that migrate to the e-liquid from closed ENDS components and e-liquid containers (low-density polyethylene (LDPE) bottles, polyethylene terephthalate (PET) bottles). Testing was conducted by Eurofins BioPharma Product Testing laboratory, a contract laboratory specializing in pharmaceutical extractable and leachable analyses. Semiquantitative and nontargeted analyses were conducted using gas chromatography-mass spectrometry (GC-MS) for volatile compounds and ultra-high-performance liquid chromatography-photo diode array-mass spectrometry (UPLC-PDA-MS) for semi- and nonvolatile compounds. Semiquantitative and targeted analyses were conducted using GC-MS-selected ion monitoring (GC-MS-SIM) for polycyclic aromatic hydrocarbons (PAHs) and inductively coupled plasma MS (ICP-MS) for metals. All relevant peaks were tentatively identified using mass spectral libraries and identification criteria. Across all 47 products examined in the extractable study, 19 unique (i.e., distinct, identified compounds after removing duplicates) and 101 unknown semi- and nonvolatile compounds, 1591 unique and 18 unknown volatile compounds, 9 unique PAHs, and 12 unique metals were observed. The five products from each product type with the highest number and concentration of extractables above the preestablished thresholds across all four analytical methods were examined in the leachable study. Closed ENDS had the greatest number of leachables (243 compounds), while LDPE and PET bottles had comparable numbers of leachables (53-65 compounds). In summary, this study details a comprehensive E&L analysis and peak identification approach for ENDS. These findings demonstrate that established pharmaceutical E&L methodology can be applied to ENDS components and e-liquid containers, and certain methodological parameters (e.g., selection of solvents and libraries) may need to be optimized for ENDS products.",
        "42572742": "ID: 42572742\nTitle: Solvent-Free One-Pot Preparation of Lignin-Ferric Nanoparticles for Enhanced Antibacterial Therapy.\nAbstract: The global rise of antibiotic-resistant bacterial infections has intensified the need for scalable and biocompatible antimicrobial nanomaterials. Lignin is an abundant renewable biopolymer with intrinsic antimicrobial activity, but its limited aqueous processability and modest antibacterial efficacy restrict its direct application. Lignin-ferric nanoparticles (LS-Fe) were prepared through an aqueous one-pot process using sodium lignosulfonate (SLS) as the lignin precursor and Fe3\u207a as the coordination component, without the use of organic solvents. The nanoparticles were characterized for size, dispersity, surface charge, morphology, Fe incorporation, and batch-to-batch reproducibility. Their antibacterial activity against Staphylococcus aureus and Escherichia coli, effects on bacterial growth, biofilm biomass, membrane integrity, intracellular reactive oxygen species (ROS), and lipid peroxidation were evaluated. Fe/ROS-modulation experiments were performed using deferoxamine, thiourea, catalase, and H2O2. Exploratory in vivo efficacy and safety were assessed in a small mouse model of S. aureus-infected wounds. LS-Fe formed stable colloidal nanoparticles with a hydrodynamic diameter of 126.63 nm, a polydispersity index of 0.19, and a zeta potential of -44.7 mV. In preliminary in vitro assays, LS-Fe showed a descriptive trend toward greater antibacterial activity than pristine SLS against both bacterial strains. LS-Fe treatment was associated with increased intracellular ROS and lipid peroxidation, bacterial membrane damage, inhibition of biofilm formation, and reduced residual biomass of preformed biofilms. The attenuation of LS-Fe-mediated antibacterial activity by deferoxamine, thiourea, and catalase, together with its enhancement by exogenous H2O2, supported a possible Fe-mediated oxidative antibacterial contribution. In the exploratory infected-wound model, topical LS-Fe treatment was associated with faster wound closure, reduced bacterial burden, and improved histological features of wound repair, while no obvious histopathological abnormalities were observed in major organs at the tested dose. Aqueous one-pot preparation of LS-Fe provides a simple organic-solvent-free strategy for integrating lignin nanoparticle formation with ferric functionalization. The preliminary findings support further investigation of LS-Fe as a sustainable antibacterial nanomaterial for infected-wound management, while larger confirmatory studies and more comprehensive mechanistic and safety evaluations remain necessary.",
        "42573342": "ID: 42573342\nTitle: Benchmarking Fourier Transform Ion Cyclotron Resonance Mass Spectrometry against Conventional Methods for the Characterization of Solvent-Fractionated Kraft Lignin.\nAbstract: Lignins are heterogeneous aromatic biopolymers whose structural complexity depends strongly on botanical origin and isolation process. Comprehensive characterization therefore typically relies on multiple complementary techniques, including gel permeation chromatography (GPC), Fourier transform infrared spectroscopy (FT-IR), pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS), and nuclear magnetic resonance (NMR) spectroscopy, resulting in labor-intensive workflows and complex data integration. Here, ultrahigh-resolution Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) is systematically benchmarked against these established methods using solvent-fractionated spruce kraft lignin as a model system. Complementary electrospray ionization (ESI) and graphite-assisted laser desorption/ionization (GALDI), combined with tandem mass spectrometry (MS/MS) and heterospectroscopic correlation analysis, reproduce fraction-dependent trends in oxygenation, aromatic condensation, and functional group distribution consistent with FT-IR, Py-GC/MS, and quantitative NMR data. While limitations remain for molar mass distributions and linkage quantification, FT-ICR-MS can serve as an advanced, high-throughput complementary screening platform that enables streamlined, comparative molecular-level lignin profiling with reduced analytical complexity.",
        "42573816": "ID: 42573816\nTitle: Deep eutectic solvent-based extraction and recovery of phenolic compounds: From conventional media to switchable recovery strategies.\nAbstract: Phenolic compounds are widely distributed in plant-derived matrices and are important targets in food, pharmaceutical, agricultural, and biomass-utilization fields. Their reliable determination depends strongly on efficient sample preparation, but conventional organic solvent extraction often raises concerns related to solvent consumption, toxicity, selectivity, and sample-cleanup burden. Deep eutectic solvents (DESs) have been widely explored as tunable extraction media for phenolic compounds because their polarity, viscosity, hydrogen-bonding capacity, and solvation behavior can be adjusted by changing the hydrogen-bond acceptor, hydrogen-bond donor, molar ratio, and water content. However, conventional DES systems still face important limitations, including slow mass transfer caused by high viscosity, difficulty in solvent removal due to low volatility, incomplete analyte recovery, and possible interference with chromatographic or mass-spectrometric analysis. This review summarizes conventional DES-based extraction of phenolic compounds as the baseline, and then focuses on responsive switchable DESs (RS-DESs) as recovery-oriented solvent systems. RS-DESs can undergo reversible changes in phase behavior, polarity, miscibility, or solvation ability in response to temperature, pH, CO2/N2, or ionic strength, thereby facilitating extraction, phase separation, analyte recovery, and solvent recycling. Particular attention is paid to extraction mechanisms, structure-property relationships, quantitative comparison with conventional DES systems, and analytical compatibility with HPLC, LC-MS, and related sample-cleanup workflows. Finally, the review discusses current scientific, analytical, and industrial challenges, including switching reproducibility, phenolic stability, DES residues, matrix effects, toxicity, biodegradability, and scale-up feasibility.",

Aerial flowering parts were sequentially extracted with solvents of varying polarity. Extracts were analyzed for yield, phytochemical composition, and total phenolic and flavonoid contents and HPLC.\u00a0LC-MS/MS analysis in negative ion mode was performed for detailed compound identification. Antioxidant activity was measured using the DPPH assay. Antibacterial activity against Gram-positive and Gram-negative bacteria was evaluated via agar diffusion and MIC/MBC methods. Anti-inflammatory potential was determined in vitro through RBC membrane stabilization (hemolysis) assay. Cytotoxicity and antiviral activity were examined using MTT and cell-based assays on HepG2 and Vero cells. The molecular mechanism of anticancer activity was investigated through qPCR analysis of apoptosis-related genes (Bax, Caspase-3, Caspase-9, and Bcl-2) in HepG2 cells. Antiviral efficacy against Hepatitis A virus (HAV) and Coxsackievirus B4 (CoxB4) was further validated by RT-qPCR quantification of viral RNA copy numbers. The ethanolic extract showed the highest yield (14.23%) among the tested solvents and richest phytochemical profile, with rutin as the predominant compound.\u00a0LC-MS/MS identified 24 compounds including threonic acid, hypoxanthine, indole-3-carboxylic acid, N-methyllysine, 4-methyl-2-oxovaleric acid, 4-isopropylbenzoic acid, methionine, N-2-fluorenylacetamide, arachidic acid, N-methylanthranilic acid, carbocysteine, fructose-1,6-bisphosphate, lumazine, 5-aminoimidazole-4-carboxamide, and 3-isochromanone. It exhibited significant antioxidant activity (IC50\u2009=\u200921.08\u00a0\u00b5g/mL) and antibacterial effects against both Gram-positive and Gram-negative bacteria.

Unequal ionization of carbohydrates and significant fragmentation have been reported. The introduction of suitable dopants into the ion source shows promise for limiting fragmentation. To investigate these ionization disturbances, both direct infusion (DI) and modified direct insertion probe (DIP) APCI coupled with a Fourier-transform ion cyclotron resonance mass spectrometry (FT-ICR MS) were employed. Solvents with increasing proton affinity (PA) were used to assess solvent PA influence in DI-APCI ionization processes. The DIP system was modified to enable the introduction of an inert gas stream passing through a dopant-rich atmosphere prior to entering the ion source. A significant PA difference between the solvent and the analyte promotes carbohydrate dissociation after their ionization. Experiments without solvent and with deuterated compounds showed that carbohydrate ionization and dissociation may be self-induced by water formed during carbohydrate dehydration. The introduction of ammonia in the ion source promoted the [M\u2009+\u2009NH4]+ adduct formation, reducing ionization-induced dissociation and increasing the intensity of the carbohydrate signal by at least one order of magnitude in DI-APCI. The method was successfully applied to both standards and cellulose pyrolysis samples. The dopant-assisted APCI (dAPCI) approach appears highly promising for the rapid assessment of biomass fast pyrolysis, particularly when highly oxygenated compounds are key markers. Careful selection of dopants and solvents is essential in carbohydrate analysis to preserve analyte structural integrity during ionization.",

Extraction was assisted with ultrasound (40\u2009kHz, 30\u00b0C). The sample-to-solvent ratio was 1:14, and extraction was performed separately for seeds and peels. The proximate composition of peel and pulp stood out for their high carbohydrate content (52.12 and 90.99\u2009g/100\u2009g d.m., respectively), whereas the seeds showed values of fiber, protein, and fat of 29.48, 26.33, and 23.77\u2009g/100\u2009g d.m., respectively.

The thymocyte selection-associated high-mobility group box-3 (TOX3) gene is suggested to influence NSCL/P development, though its role remains unclear. This study investigates environmental factors associated with NSCL/P and explores the association between TOX3 mutations and these factors. A cross-sectional retrospective study was conducted amongst 50 Malay patients with NSCL/P who underwent surgery at Hospital Universiti Sains Malaysia (January 2022-January 2023). Participants were selected based on inclusion criteria from electronic medical records. Data on environmental and familial risk factors were obtained using validated pro formas, and TOX3 gene copy number was analysed using quantitative polymerase chain reaction. Cleft lip and palate (CL/P) were the most common deformity, accounting for 74% of cases, and 56% of patients were male. Significant risk factors for NSCL/P included consanguineous marriage, family history of clefts, maternal radiation exposure, traditional medicine use, allergies, paternal smoking and infant heart anomalies (P \u2264 0.05). Maternal pregnancy age was inversely correlated with TOX3 expression in CL/P cases (r = -0.387, P = 0.018). The findings highlight complex gene-environment interactions in NSCL/P aetiology. Genetic predisposition, parental exposures and maternal factors jointly increase risk. Larger studies are needed to confirm these findings and further investigate gene-environment interactions in NSCL/P. The study underscores the role of TOX3 and environmental influences in NSCL/P pathogenesis, supporting targeted prevention and genetic counselling in the Malay population.",
        "42578478": "ID: 42578478\nTitle: Fluorinated EC analogues as co-solvents in EMC-based electrolytes for Li-ion batteries: a computational study.\nAbstract: The growing demand for high-energy-density lithium-ion batteries calls for electrolytes capable of stable operation at elevated voltages. Conventional carbonate-based systems, such as ethylene carbonate (EC) and ethyl methyl carbonate (EMC), suffer from limited oxidative stability and rapid degradation under such conditions. Fluorination of carbonates has emerged as an effective strategy to enhance electrochemical stability and cycling performance. In this study, we computationally investigate electrolyte formulations composed of EMC and fluorinated EC derivatives as co-solvents to elucidate how molecular fluorination influences solvation structure and ion transport. Quantum mechanical calculations reveal that among the studied species, trans-difluoroethylene carbonate (DFEC) exhibits the widest HOMO-LUMO gap (8.727 eV), indicating a higher electrochemical stability window, whereas non-fluorinated EC shows the strongest Li+ coordination, consistent with its superior ion-pair dissociation ability. Radial distribution functions and cluster analyses further confirm that electrolytes containing fluorinated solvents exhibit weaker ionic dissociation and higher ion aggregation compared to the EC-based system. While most fluorinated systems show a substantial increase in single-ion diffusion, true ionic conductivity is generally decreased upon fluorination with the exception of TFPC/EMC. This decrease is due to extensive clustering and absence of cyclic co-solvent in Li+ coordination, both of which lead to the formation of fewer charge carriers. The TFPC/EMC and FEC/EMC formulations exhibit comparable ionic conductivity values to EC/EMC (3.02 mS cm-1 and 2.74 mS cm-1 respectively, compared to 2.85 mS cm-1) and are both the highest among the fluorinated systems. Finally, van Hove correlation analysis provides a detailed view of Li+ transport, revealing that the short-time peak of Li+ generally decays more prominently and displaces farther upon fluorination.",

This study systematically investigated the occurrence of 50 FLCMs in 300 urine samples collected from 150 couples living in Tianjin, China. Among the 50 target analytes, 42 were detected, with total FLCM concentrations (\u2211FLCMs) ranging from 1.59 to 34.60 ng/mL (median: 7.45 ng/mL), which were substantially higher than reported urinary levels in Beijing and Guangdong populations. The predominant compounds identified were DTMTPT (4-[difluoro(3,4,5-trifluorophenoxy)methyl]-2',3,5-trifluoro-4'-pentyl-1,1':4',1'-terphenyl), CFPEB (3-fluoro-4-cyanophenyl 4-ethylbenzoate), EDPBB (1-ethoxy-2,3-difluoro-4-[(trans,trans)-4'-propyl[1,1'-bicyclohexyl]-4-yl]benzene), DPPCB (2,3-difluoro-1-propoxy-4-[(trans,trans)-4'-propyl[1,1'-bicyclohexyl]-4-yl]benzene), and EFPT (4\u2033-ethyl-2'-fluoro-4-propyl-1,1':4',1\u2033-terphenyl), with DTMTPT and CFPEB representing the largest contributions at 20.5% and 19.1% of total concentrations, respectively. Demographic analysis revealed that urinary EFPT concentrations were significantly lower in females than in males (P < 0.05), and gender exerted a more pronounced influence on exposure than cohabitation. Individuals aged <30 years exhibited marginally elevated FLCM exposure compared to those \u226530 years, whereas body mass index, smoking status, and alcohol consumption showed no significant associations with urinary FLCM concentrations (P > 0.05). Correlation analysis and molecular docking simulations demonstrated that CFPEB and DTMTPT were significantly positively correlated with serum alanine aminotransferase levels (P < 0.05), and all five major FLCMs exhibited stable binding affinities to the aryl hydrocarbon receptor (AhR), suggesting potential hepatotoxicity. Screening-level hazard quotient (HQ) assessment indicated low health risks under current exposure scenarios. This study addresses a critical data gap regarding FLCM exposure in the general adult population of China and provides foundational data and scientific evidence for characterizing human exposure patterns and informing risk management strategies for this emerging contaminant class.",

T.G. Hartley (syn. Evodia rutaecarpa (Juss.) Benth., Rutaceae), known as Wuzhuyu in Chinese and Evodiae Fructus (EF) in English, is a traditional Chinese medicine (TCM) with a history of over two thousand years. It was first documented in Shen Nong's Herbal Classic for its efficacy in dispersing cold, relieving pain, and alleviating nausea, vomiting, and diarrhea, leading to its historical use in managing gastrointestinal ailments. However, the clinical application of EF has been limited due to its associated hepatotoxicity. Existing studies have confirmed that evodiamine, rutaecarpine and other alkaloids induce hepatotoxicity via multi-pathways, but the core toxic fraction, multi-component synergistic effects and systematic toxic network of EF remain unclear. This study aims to identify the key hepatotoxic fraction of Evodiae Fructus (EF) and elucidate its underlying mechanisms. A high-throughput zebrafish model was used to screen EF extracts with different polar solvents. The hepatotoxicity of the target fraction was validated in mice. UPLC-Q-TOF-MS/MS, integrated network pharmacology, proteomic and transcriptomic analyses were performed in zebrafish and mice to screen toxic pathways, with western blot and qRT-PCR validation. High-throughput zebrafish screening of five polar extracts of EF identified the dichloromethane extract (DEEF) as the core hepatotoxic fraction. Both zebrafish and mouse models consistently indicated that DEEF induced a dose-dependent elevation of serum ALT, AST, and TBA levels, disrupted the architecture of hepatic tissue, and was accompanied by marked hepatocyte apoptosis. In mice, Masson's trichrome staining further revealed abnormal collagen deposition, along with extensive infiltration of inflammatory cells. UPLC-Q-TOF-MS/MS analysis identified 73 compounds in DEEF, with 48 alkaloids (indole and quinolone types) being the dominant components, in addition to flavonoids, limonoids, and organic acids. Integrated network pharmacology, transcriptomic and proteomic analyses revealed dose-dependent global alterations in hepatic gene and protein expression profiles. Mechanistically, DEEF upregulated bile acids (BAs) synthesis enzymes (CYP7A1, CYP27A1) and downregulated efflux transporters (BSEP, MRP2). These changes were associated with activation of PI3K-AKT/MAPK/p53/NF-\u03baB pathways and modulation of the Bax/Bcl-2/Caspase-3 apoptotic axis, as indicated by multi-omics enrichment and validated by protein and gene expression analyses. This study is the first to confirm that DEEF represents the core toxic fraction of EF and to disclose that its hepatotoxic mechanism is driven by the crosstalk between BAs metabolism disorder and multi-signaling cascade. Our findings fill the research gap between studies on crude extract and monomers, and provide a critical foundation for targeted detoxification and safe clinical application of EF.",

However, a comprehensive understanding of their chemical diversity remains limited. Insufficient information exists on metabolite variation between plant parts and the influence of solvent polarity on metabolite recovery. Therefore, this study aimed to characterize the metabolomic profiles of the shoots and root extracts of both species using solvents of varying polarity to evaluate plant part-specific metabolite distribution and solvent effects on metabolome coverage. Untargeted ultra-high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS)-based metabolomics and molecular networking were employed for metabolite analysis. Principal component analysis (PCA) did not reveal clear clustering of A. ochroleuca and A. mexicana, suggesting similarities in their metabolomic profiles. A total of 15 and 13 metabolite classes, yielding 59 and 54 metabolites, were identified in A. ochroleuca and A. mexicana, respectively, including flavonoids, terpenoids, phenolic compounds, fatty acids, and monoterpenoids. Argemone ochroleuca exhibited higher metabolite abundance, particularly in methanol and acetone extracts, and with shoots showing higher abundance than roots, with flavonoids being the dominant class. The findings show that LC-MS metabolomics, molecular networking, and careful solvent selection are effective for identifying key metabolites with potential applications in crop protection.",
        "42589302": "ID: 42589302\nTitle: Solvent Interaction Analysis: A New Lens for Protein Structure and Diagnostics.\nAbstract: Aqueous two-phase systems (ATPSs) provide a versatile, fully aqueous platform for probing solute-water interactions and protein structure. This review first surveys the diversity and phase behavior of biphasic aqueous systems formed by polymers and salts. We describe how phase diagrams characterize ATPS formation and composition and how both polymer chemistry and salt identity, rather than molecular size alone, govern phase separation by modulating the solvent properties of water. Building on a modified binodal model, we show that phase separation and solute partitioning can be understood in terms of changes in aqueous solvent dipolarity/polarizability, hydrogen-bond donor/acceptor properties, hydrophobicity, and electrostatics, quantified via solvatochromic probes and homologous solute series. These measurements underpin solvent interaction analysis (SIA), in which the partition coefficients of small molecules and proteins across panels of ATPSs are used to generate \"structural signatures\" that sensitively report on amino acid substitutions, conformational changes, aggregation, ligand binding, osmolyte effects, and post-translational modifications, independent of protein size. We discuss how SIA can be implemented in vial-, plate-, and microfluidic formats and combined with diverse analytical readouts (HPLC, MS, colorimetric assays, and immunoassays), and we contrast this structure-focused approach with conventional concentration-only proteomic and biomarker strategies. Particular emphasis is placed on structure-based biomarker discovery, where disease-relevant shifts in proteoform distributions-especially glycosylation changes-are often more informative than bulk protein levels and where SIA can complement or simplify complex glycomics and top-down proteomics workflows. As a case study, we describe the recently FDA-approved IsoPSA assay, which applies SIA principles to prostate-specific antigen by measuring cancer-associated structural alterations in circulating PSA via its partition behavior in a proprietary ATPS. IsoPSA generates a single index that discriminates between high-grade prostate cancer and benign and low-grade conditions. Prospective, longitudinal, and MRI-integrated clinical studies demonstrate that IsoPSA improves pre-biopsy risk stratification, reduces unnecessary biopsies, and provides robust negative and positive predictive values within the PSA \"gray zone.\" Collectively, the data support aqueous solvent interaction analysis as a broadly applicable, mechanistically grounded technology for protein characterization, drug-protein interaction studies, and structure-centric biomarker development, exemplified by the clinical translation of IsoPSA.",

Traditional risk factors do not explain all patients' risks; thus, the research of additional biomarkers to refine cardiovascular risk prediction has attracted considerable interest in recent years. Genetic factors, as well as air pollution exposure, among nontraditional factors, have been found to be critical determinants of CV risk. Accordingly, this narrative review aims to provide a comprehensive summary of the literature (PubMed) on the combined effects of air pollution and genetic susceptibility on CVD risk. Although different limitations and pitfalls are still to be solved, available evidence suggests that genetic variants (especially genes related to detoxification and inflammation) are involved in the association between air pollution exposure and CV adverse events. Thus, this research area could provide further knowledge of the etiology of CVD, offering new tools for targeted prevention and treatment of more susceptible subjects from a more personalized medicine point of view.",

However, the traditional polymer synthesis and/or polymer-based separator modifications have mostly been carried out using harmful and expensive organic solvents. In this study, a powder-type polyimide (PI) was synthesized using water as a solvent, and then PI-particle-containing coating slurries were prepared in an aqueous dispersion medium. The coating slurries were applied on a polyethylene (PE) separator to obtain PI-particle-coated PE (PI-PE) separators. Thermal and mechanical properties were evaluated for the PI-PE separators. Electrolyte uptake, porosity, air permeability, and ionic conductivity of the separators were also evaluated. The electrochemical properties of coin cells assembled with the PI-PE separator were evaluated by charge-discharge property. Coating of PI particles improves the thermal stability and electrolyte wettability of the PE separator, and LiCoO2/PI-PE separator/Li half-cells showed battery performance similar to that of bare PE half-cells. This work offers insights into the simple, eco-friendly preparation of a separator with excellent thermal stability, electrolyte wettability and effective ionic conductivity.",

Existing PML risk stratification algorithms were originally developed and validated within a single-assay framework based on the STRATIFY JCV\u2122 DxSelect\u2122 platform. The recent introduction of natalizumab biosimilars in Europe has coincided with implementation of IMMUNOWELL\u2122 JCV IgG assay, creating a multi-assay environment in which quantitative antibody index values and binary serostatus classifications may not be directly interchangeable. We conducted a structured narrative review of comparative studies evaluating STRATIFY and IMMUNOWELL performance in natalizumab-treated cohorts. Outcomes included seroprevalence, qualitative concordance, quantitative index distribution, reclassification across established PML risk categories, and reported changes in clinical management. Across analytical validation datasets and real-world populations, IMMUNOWELL classified a higher proportion of individuals as JCV-positive than STRATIFY. Reported binary discordance ranged from approximately 6% to 38%, with a predominance of IMMUNOWELL-positive/STRATIFY-negative classifications. Longitudinal studies further showed that many low-positive IMMUNOWELL results fluctuated or reverted over time. The available evidence suggests that the transition from a mono-assay to a multi-assay testing environment introduces a previously underrecognized source of variability in PML risk stratification. In the absence of a biological gold standard for latent JCV infection, interpretation of discordant results should integrate antibody magnitude, longitudinal persistence, and clinical context rather than relying on binary thresholds.",

This prospective cohort study examined associations of maternal serum OPE concentrations at 9 to 13+6 gestational weeks with infant birth weight, large for gestational age (LGA), and small for gestational age (SGA). Among 1, 039 pregnant females in a Qingdao birth cohort, 16 serum OPEs were measured using gas chromatography-tandem mass spectrometry (GC-MS/MS). Individual OPEs were evaluated per interquartile-range increase in ln-transformed concentration using multivariable linear regression and modified Poisson regression. Quantile g-computation (Qgcomp), weighted quantile sum (WQS) regression, and Bayesian kernel machine regression (BKMR) assessed OPE mixtures. Tris(isobutyl) phosphate (TIBP) and tris(2-ethylhexyl) phosphate (TEHP) were associated with higher birth weight [TIBP: \u03b2 = 77 g, 95% confidence interval (CI): (37, 117); TEHP: \u03b2 = 40 g, 95% CI: (18, 63)]. TEHP was associated with higher LGA risk [adjusted risk ratio (aRR) = 1.27, 95% CI: (1.09, 1.48)] and lower SGA risk [aRR = 0.71, 95% CI: (0.57, 0.90)]; p-cresyl diphenyl phosphate (pCDP) was also associated with lower SGA risk [aRR = 0.69, 95% CI: (0.53, 0.91)]. In Qgcomp models, total OPE mixture exposure was associated with higher LGA risk [aRR = 1.41, 95% CI: (1.10, 1.80)]. Alkyl-substituted OPE mixture was associated with higher LGA risk in Qgcomp and higher birth weight in WQS; halogenated OPE mixture showed no significant associations. Maternal serum concentrations of selected OPEs at 9 to 13+6 gestational weeks, particularly alkyl-substituted OPEs, were associated with higher birth weight and LGA risk. These findings warrant confirmation in studies with repeated exposure assessment and additional longitudinal fetal growth indicators.",

Although pesticides, industrial solvents, heavy metals, and air pollutants have long been implicated as potentially modifiable PD risk factors, climate change is now reshaping and amplifying these hazards through rising temperatures, worsening air quality, increased pesticide demand, extreme weather events, and wildfire-related particulate matter.This narrative review moves beyond a conventional exposure-based summary by integrating environmental toxicology, climate science, epidemiology, and mechanistic neuroscience to reframe PD risk within the context of planetary health. We summarize evidence linking major environmental hazards to PD pathogenesis, emphasizing convergent mechanisms such as oxidative stress, mitochondrial dysfunction, impaired proteostasis, neuroinflammation, blood-brain barrier disruption, and \u03b1-synuclein aggregation. We further discuss how climate-related changes may intensify these pathways and disproportionately affect vulnerable populations, including agricultural workers, older adults, socioeconomically disadvantaged communities, and individuals living in rapidly industrializing or climate-sensitive regions. Importantly, we highlight clinical and public health implications by proposing that structured environmental and occupational exposure assessment should be incorporated into PD risk evaluation, early recognition, preventive counseling, and research design. We also discuss exposure reduction, workplace protection, environmental monitoring, and regulatory policy as prevention-oriented strategies. By positioning environmental hazards and climate change as interconnected, underrecognized, and potentially modifiable contributors to PD, this review provides a framework for clinicians, researchers, and policymakers seeking to reduce the future global burden of neurodegenerative disease. Parkinson's disease (PD) is a common neurodegenerative disorder that develops over time and affects movement, balance, and many daily activities. While genes play a role, most cases of PD do not arise solely from genetics. Growing evidence shows that environmental exposures, such as pesticides, industrial chemicals, heavy metals, and air pollution, can increase the risk of developing PD. Importantly, many of these exposures can be reduced or prevented. Climate change is worsening these environmental risks. Higher temperatures, poorer air quality, increased pesticide use, and more frequent wildfires are increasing human exposure to harmful pollutants worldwide. Together, these changes may increase the number of people affected by PD, especially in communities already facing environmental or social disadvantages. This review explains how environmental toxins can damage brain cells through shared biological processes, including oxidative stress, inflammation, and abnormal protein buildup. It also highlights regions and populations that may be more vulnerable to these risks. From a healthcare perspective, understanding a person's environmental and work-related exposures can help identify those at higher risk, support earlier recognition of PD, and guide prevention advice. Overall, environmental toxins and climate change are underrecognized yet actionable determinants of PD. Increasing awareness, improving environmental protections, and integrating exposure history into clinical care are key steps toward reducing the future global burden of PD.",

Albendazole (ALB), the nowadays anti-trichinellosis drug, has side effects and insufficient effectiveness. Ficus species have ubiquitous health benefits. The current work aimed to assess the in vitro anti-trichinellosis potential of seven Ficus species compared to the reference drug, ALB. Fourteen crude extracts from seven Ficus species (spp.) leaves were prepared using 70% methanol and aqueous solvents. Trichinella spiralis (T. spiralis) adult worms were isolated from infected mice, cultivated on a 24-well tissue culture plate, and subjected to the crude Ficus spp. extracts and ALB in culture media. The efficacy of the tested compounds was evaluated using parasitological analysis and electron microscopy (SEM). Preliminary phytochemical screening and total phenolic content were performed on Ficus spp. extracts showing the most promising effects. In addition, GC-MS analysis was performed on the most active extract to determine its chemical composition. The parasitological analysis revealed that Ficus microcarpa (F.m) had the most promising effects, followed by Ficus sycomorus (F.s) and Ficus nitida (F.n) with the methanolic extracts' LC50 of 12.8\u00a0\u00b5g/mL, 31.5\u00a0\u00b5g/mL, and 42.9\u00a0\u00b5g/mL, respectively, compared to the ALB (52.5\u00a0\u00b5g/mL). SEM results documented changes and a loss of the typical tegumental structure and morphology in adult T. spiralis worms. The GC-MS analysis of F.m methanolic extract yielded 26 compounds, including fatty acids, esters, tricyclic diol, and glucosinolates. Molecular docking studies further supported these results, with high binding affinities among the major compounds of F.m and the tubulin beta chain of T. spiralis, an essential protein for parasite survival. The current study emphasizes the promising potential of Ficus species, especially F.m, as natural sources for the development of antiparasitic agents for the therapy of trichinellosis.",

In this study, an ultrasound-assisted deep eutectic solvent (UAE-DES) strategy was developed for the efficient extraction of polyphenols from Cortex Mori, combined with macroporous resin enrichment and subsequent chemical and functional characterization. Among 36 deep eutectic solvents evaluated, betaine-sucrose (DES-6) exhibited the best extraction performance. Response surface methodology optimized the UAE-DES conditions as 35% water content, 57 \u00b0C, liquid-to-solid ratio of 90 mL/g, ultrasound time of 20 min, and power of 520 W, achieving a total phenolic yield of 232.93 \u00b1 0.95 mg GAE/g, which was 28.31% and 32.78% higher than the highest yields obtained using methanol and ethanol, respectively. Scanning electron microscopy revealed that ultrasound-DES treatment caused pronounced erosion, pore formation, cracking, and partial collapse of plant cell walls, thereby facilitating solvent penetration and mass transfer. After purification using HPD-100 resin, UHPLC-Q-Orbitrap HRMS identified 58 polyphenolic compounds, including 11 reported from Cortex Mori for the first time. The 70-W2 fraction exhibited strong tyrosinase inhibitory activity (IC50 = 1.92 \u00b1 0.03 \u00b5g/mL), surpassing kojic acid (IC50 = 12.54 \u00b1 0.21 \u00b5g/mL). Affinity ultrafiltration coupled with LC-MS (UF-LC-MS) screening identified seven potential tyrosinase-binding ligands. Molecular docking showed that 2-hydroxynaringenin 4'-O-glucoside had the most favorable predicted docking score (-10.5 kcal/mol), followed by mulberroside A and 5,7,2',6'-tetrahydroxyflavanone. These candidates require further biochemical and in vivo validation. In addition, the optimized DES retained 90.51 \u00b1 2.28% of its initial extraction performance after the third reuse cycle, while FTIR, viscosity, and density analyses supported its short-term physicochemical stability. These results demonstrate that ultrasound-assisted deep eutectic solvent extraction provides an integrated and resource-efficient approach for polyphenol recovery, activity-oriented enrichment, and prioritization of potential tyrosinase-binding constituents from Cortex Mori.",

Exposure assessments combined national dietary survey data, regulatory limits, industry reports, and surveillance findings. Under the theoretical maximum scenario, estimated daily intake (EDI) approached the temporary acceptable daily intake (tADI) of 0.3\u2009mg/kg bw/day, with P95 values exceeding it 1.5-1.9 times, indicating potential risk for high-intake subgroups. In contrast, enterprise-reported and monitoring scenarios yielded EDI values well below the tADI, suggesting negligible risk under typical conditions. Marinated meats, animal fats and compound seasonings were the primary contributors to exposure. Rosemary components were also detected in non-authorised food categories, implying possible carry-over effects. Overall, current use patterns appear safe, but improved additive traceability and targeted surveillance are needed to refine exposure assessments and support enforcement of regulation.",

Black carbon (BC), a carbonaceous particulate generated through the incomplete combustion of fossil fuels, biomass, and biofuels, is recognized as a major short-lived climate pollutant with significant implications for atmospheric processes and agricultural sustainability. Unlike engineered biochar, atmospheric BC acts as an environmental stressor through deposition on plant surfaces and accumulation in agroecosystems, yet its direct impacts on crop physiology remain insufficiently understood. This review synthesizes current knowledge on the physicochemical characteristics, environmental pathways, and plant stress mechanisms associated with atmospheric BC while explicitly distinguishing it from intentionally applied biochar. Available evidence indicates that BC influences plant performance through multiple interconnected pathways, including reduced light availability, stomatal obstruction, disruption of photosynthesis, oxidative stress induced by excessive reactive oxygen species (ROS), chloroplast dysfunction, hormonal imbalance, and alterations in nutrient cycling and soil microbial communities. However, much of the mechanistic evidence is derived from studies on biochar, carbon nanomaterials, or other particulate pollutants, highlighting a critical gap in plant-specific evidence under realistic atmospheric BC exposure. Regional studies, particularly from the Indo-Gangetic Plain, demonstrate that elevated BC and associated aerosol loading contribute to reduced crop productivity and increased food security risks, although these impacts often reflect the combined influence of multiple atmospheric stressors rather than BC alone. The review further examines current limitations in BC exposure quantification, emphasizing the absence of agronomic dose-response thresholds and standardized field-based assessment methods. Emerging approaches, including leaf-based biomonitoring and isotopic analyses, are discussed as promising tools for future exposure assessment. Finally, key research priorities are identified, including the generation of plant-specific mechanistic evidence, development of realistic dose-response frameworks, integration of BC into crop simulation models, and implementation of long-term field studies to improve risk assessment and support evidence-based mitigation strategies for sustainable agriculture.",

In the current study, extraction was performed from O. racemosa using the maceration method with several extraction solvents. The extracts were examined for their antioxidant and enzyme-inhibitory activities and their effects on cell viability. In high-performance liquid chromatography-MS/MS analysis, a total of 31 compounds was detected across all studied extracts. The EtOH and EtOH/water extracts consistently exhibited the highest antioxidant capacities in almost all tested assays. Similarly, EtOH and EtOH/water extracts showed vigorous anti-AChE activity, measuring 2.88 and 2.35\u2009mg/GALAE, respectively. In the cell viability assay, both EA and EtOH extracts of O. racemosa demonstrated potent cytotoxicity, significantly reducing viability in normal (HEK293) and cancer cell lines (HepG2, SH-SY5Y), indicating high toxicity without selectivity. Molecular docking screened 384 theoretical compound-target combinations and retained 251 unique complexes with docking scores of -7.0 kcal/mol or lower after duplicated entries were removed.

Accurate and rapid detection of prohibited substances at their lowest levels in complex biological matrices, such as blood, urine, and plasma, is crucial for reliable anti-doping analysis. This critical review focuses on the applications of mass spectrometry (MS) for the detection of doping agents across diverse biological matrices. Special emphasis is given to advanced mass spectrometry platforms, particularly LC-QQQ-MS, LC-QTOF-MS, Orbitrap-MS/MS, and IRMS which are widely used for the routine screening, confirmation, and identification of emerging doping agents. Microsampling approaches such as dried blood spots (DBS) and volumetric absorptive microsampling (VAMS) provide superior alternatives to traditional sampling. Furthermore, comprehensive understanding of sample pretreatment and analytical techniques is essential.

To address these limitations, a novel effervescent-assisted dispersive liquid-liquid microextraction (EA-DLLME) strategy based on ternary quasi-hydrophobic natural deep eutectic solvents (NADESs) was developed. The NADESs, composed of terpenoids, long-chain alcohols, and short-chain carboxylic acids, were synthesized and combined with Na2CO3 to form an effervescent system. The hydrophilicity of the short-chain carboxylic acid enabled in situ decomposition, while the agitation effect of CO2 bubbles facilitated rapid extraction. FT-IR and 1H NMR characterized the solvent structure and dispersion mechanism. Under optimized conditions via response surface methodology and GC-MS analysis, the method exhibited a linear range of 0.5-1000 ng mL-1 (R2 > 0.99) for the three target TFs (myclobutanil, tebuconazole, and epoxiconazole), with limits of detection of 0.017-0.030 ng mL-1. The recoveries of spiked samples ranged from 89.17% to 111.2%, with relative standard deviations below 9.5%. Density functional theory calculations including electrostatic potential, Independent Gradient Model, and Reduced Density Gradient reveal that the NADES forms through electrostatic complementarity and a hydrogen-bond network, and that the extraction with TFs occurs via directional hydrogen bonding between triazole nitrogen and the hydroxyl group of thymol, with a binding energy of -23.66 kcal mol-1, further stabilized by van der Waals forces. This approach effectively overcomes the poor retention and low efficiency associated with traditional reversed-phase extraction, offering a simple, green, and practical tool for monitoring trace TFs in complex water samples.",

This total diet study quantified chromium (Cr) and barium (Ba) in foods commonly consumed in Shiraz, Iran, and evaluated the associated health risks. A total of 108 food items representing 20 food groups yielded 545 samples (540 food and 5 drinking water samples), which were analyzed by ICP-OES. Dietary intake was estimated using local consumption data, and health risks were assessed using hazard quotient (HQ), hazard index (HI), and total cancer risk (TCR) through Monte Carlo simulation (10,000 iterations). Mean Cr and Ba concentrations were 4.07 \u00b1 3.70 and 0.998 \u00b1 1.717 mg/kg, respectively. Chromium concentrations ranged from 0.68 to 10.61 mg/kg, with the highest levels in fish and fruits, while Ba concentrations ranged from 0.006 to 2.93 mg/kg and were highest in legumes and cereals. Fruits contributed the largest share of dietary Cr and Ba intake. Estimated daily intakes for a 72-kg adult were 0.12 and 0.022 mg/kg body weight/day for Cr and Ba, respectively, corresponding to 41.7% and 11.5% of the tolerable daily intakes established by EFSA and WHO. All HQ and HI values were below 1, indicating negligible non-carcinogenic risk, and screening TCR values for total Cr were within the acceptable range (10\u207b\u2076-10\u207b4). Although Cr concentrations in some foods exceeded typical background levels, overall dietary exposure remained below health-based guidance values.

The excessive swelling of flexible polymer networks, such as Nafion, often results in massive reactant crossover and diminished product yields. In this study, we report a swelling-resistant membrane engineered from functionalized 1T' phase molybdenum disulfide (MoS2). By covalently grafting acetamide groups onto the electron-rich 1T'-MoS2, we create rigid nanochannels that physically exclude organic solvents while enabling efficient proton transport. This precise molecular sieving reduces organic permeability by an order of magnitude versus commercial Nafion 117, enabling near-quantitative yields (>96%) in diverse organic electrosynthesis reactions. Bridging the gap between lab and industrial application, we demonstrate scalable fabrication of this material via slot-die coating, with the resulting large-area membranes delivering robust stability and high productivity in a scaled-up electrolyzer stack.

Although small molecules offer advantages in terms of production, stability, and accessibility, no imaging agent currently enables reliable detection of early-stage aggregates of the amyloid-\u03b2 (A\u03b2) peptide, among the earliest biomarkers in AD progression. Herein, we report a series of bis(styryl)benzene (BSB) probes derived from the methoxy-X04 scaffold and a systematic structure-activity investigation examining how targeted molecular modifications, including hydroxyl positioning, (Me)HN or (Me)2N substitution, and incorporation of a 1,4-dimethyl-1,4,7-triazacyclononane (tacn) moiety, modulate A\u03b2 binding, cytotoxicity, and brain uptake. These methoxy-X04 analogues retain A\u03b2 affinity while exhibiting markedly improved cytotoxicity profiles and logD values consistent with in vivo applicability. Amyloid-\u03b2 binding was evaluated using age-dependent in situ staining of 5xFAD mouse brain sections, supported by in vitro fluorescence-based oligomer and fibril assays and in silico analyses that reveal tunable selectivity toward early versus late A\u03b2 aggregates.
