In this study, we aimed to explore the role of gut microbial tyramine in intestinal damage and MASLD development in children. We investigated the functions and mechanisms of previously isolated Enterococcus faecium B6 (E. faecium B6) and its derived tyramine in a mice model of intestinal injury and MASLD development. An integrative analysis of transcriptomics and proteomics was performed on mouse liver to explore the molecular mechanisms of tyramine in MASLD progression. Targeted metabolomics was performed using fecal samples from a hospital-based population (27 MASLD cases and 27 matched controls) to measure tyramine levels. The association of serum tyramine and MASLD risk was then validated in a school-based population, using serum samples of 294 children in the MASLD group and 235 controls. E. faecium B6 and its metabolite tyramine significantly disrupted the intestinal barrier and increased intestinal permeability in mice. Tyramine supplementation promoted MASLD-related metabolic phenotype in mice. Multi-omics analysis indicated that the PPAR signaling pathway played an important role in the molecular mechanisms. Tyramine contributed to lipid accumulation mainly by increasing lipid synthesis and lipid uptake but reducing the β-oxidation processes in the mouse liver, as shown by real-time quantitative polymerase chain reaction and western blot. Furthermore, we demonstrated from the hospital-based cohort that tyramine concentration was significantly higher in the MASLD group than in the control group. Consistently, the school-based cohort demonstrated a higher risk of MASLD in the high-tyramine group compared to the low-tyramine group, with adjusted odds ratios (ORs) and 95% confidence intervals (CIs) of 3.65 (95% CI: 2.66-4.32). These results demonstrated that gut microbial tyramine effectively induced intestinal damage and facilitated MASLD development in mice. Tyramine was positively associated with the risk of MASLD in children. This study offered mechanistic insights into the pathogenesis of MASLD and opened therapeutic opportunities for such metabolic diseases."},{"quadrant":"Run1_Eval1_synthesis","attempt":1,"quote":"Fecal concentrations of tyramine, derived from gut bacterial metabolism of tyrosine and/or food, increased post-RYGB.","status":"FAIL","error":"Strict Misquote Detected!

Concurrently, fecal concentrations of tyramine, derived from gut bacterial metabolism of tyrosine and/or food, increased post-RYGB. Furthermore, emerging evidence suggests that RYGB is associated with increased colorectal cancer (CRC) risk. However, the causal link between RYGB-associated microbial metabolites and CRC risk remains unclear. Hence, this study investigated the tyrosine metabolism of Enterobacteriaceae and Enterococcaceae strains isolated from patients post-RYGB and explored the causal effects of tyramine on the CRC risk and tumorigenesis using both human colonic cancer cell line (HCT 116) and wild-type and ApcMin/+ mice. We isolated 31 bacterial isolates belonging to Enterobacteriaceae and Enterococcaceae families from the feces of patients with RYGB surgery. By culturing the isolates in tyrosine-supplemented medium, we found that Citrobacter produced phenol as a main product of tyrosine, whereas Enterobacter and Klebsiella produced 4-hydroxyphenylacetate, Escherichia produced 4-hydroxyphenyllactate and 4-hydroxyphenylpyruvate, and Enterococcus and two Klebsiella isolates produced tyramine. These observations suggested the gut bacterial contribution to increased fecal concentrations of tyramine post-RYGB. We subsequently evaluated the impact of tyramine on CRC risk and development. Tyramine induced necrosis and promoted cell proliferation and DNA damage of HCT 116 cells. Daily oral administration of tyramine for 49 days to wild-type mice resulted in visible adenomas in 5 out of 12 mice, accompanied by significantly enhanced DNA damage (γH2AX +) and an increased trend of cell proliferation (Ki67 +) in the ileum, along with an upregulated expression of the cell division cycle gene (Cdc34b) in the colon. To evaluate the impact of tyramine on intestinal tumor growth, we treated ApcMin/+ mice with the same doses of tyramine and duration. These mice showed larger colonic tumor size and increased intestinal cell proliferation and inflammation (e.g., increased mRNA expression of IL-17A and higher number of Ly6G + neutrophils) compared to water-treated ApcMin/+ control mice. Our results collectively suggested that RYGB-associated fecal bacteria could contribute to tyramine production and tyramine increased CRC risk by increasing DNA damage, cell proliferation, and pro-inflammatory responses of the gut. Monitoring and modulating tyramine concentrations in high-risk individuals could aid CRC prognosis and management.

Dietary intervention with squid-derived CS significantly attenuated characteristic UC symptoms, including body weight loss, colon shortening, and histopathological damage. Mechanistic analyses revealed that squid-derived CS exerted potent anti-inflammatory effects by downregulating key pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) and alleviated oxidative stress by enhancing colonic antioxidant capacity, as evidenced by increased activities of catalase (CAT) and superoxide dismutase (SOD) and reduced myeloperoxidase (MPO) activity. Integrated 16S rRNA gene sequencing and metabolomics analyses demonstrated that squid-derived CS profoundly restructured gut microbial community composition by enriching putative beneficial bacteria (e.g., Bifidobacterium, Clostridium, Blautia) while reducing opportunistic pathogens (e.g., Enterococcus, Sutterellaceae, Clostridia_UCG-014). This favorable microbial shift was accompanied by a reconfiguration of the intestinal metabolome, characterized by elevated production of beneficial short-chain fatty acids (SCFAs) and decreased levels of pro-inflammatory metabolites such as tyramine. Furthermore, squid-derived CS effectively enhanced intestinal barrier integrity by upregulating key tight junction proteins (ZO-1, occludin, claudin-1), thereby preventing bacterial lipopolysaccharide (LPS) translocation and associated liver injury, as indicated by reduced serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Collectively, these findings demonstrate that dietary squid-derived CS protects against UC by modulating gut microbiota composition to enrich beneficial taxa, restoring microbial metabolite homeostasis, reinforcing the intestinal epithelial barrier, and suppressing inflammatory responses and oxidative stress. This study provides the first evidence that squid-derived CS acts as a novel and promising marine prebiotic candidate for gut health promotion, highlighting its potential as a sustainable functional ingredient derived from processing waste for gut-health-promoting foods."},{"quadrant":"Run1_Eval1_synthesis","attempt":1,"quote":"Enterococcus-derived tyramine suppresses ISC proliferation, thereby impairing epithelial regeneration and exacerbating DSS-induced colitis through ADRA2A.","status":"PASS","error":"","abstract_text":"ID: 38788722\nTitle: Enterococcus-derived tyramine hijacks α2A-adrenergic receptor in intestinal stem cells to exacerbate colitis.\nAbstract: Inflammatory bowel disease (IBD) is characterized by dysbiosis of the gut microbiota and dysfunction of intestinal stem cells (ISCs). However, the direct interactions between IBD microbial factors and ISCs are undescribed. Here, we identify α2A-adrenergic receptor (ADRA2A) as a highly expressed GPCR in ISCs. Through PRESTO-Tango screening, we demonstrate that tyramine, primarily produced by Enterococcus via tyrosine decarboxylase (tyrDC), serves as a microbial ligand for ADRA2A. Using an engineered tyrDC-deficient Enterococcus faecalis strain and intestinal epithelial cell-specific Adra2a knockout mice, we show that Enterococcus-derived tyramine suppresses ISC proliferation, thereby impairing epithelial regeneration and exacerbating DSS-induced colitis through ADRA2A. Importantly, blocking the axis with an ADRA2A antagonist, yohimbine, disrupts tyramine-mediated suppression on ISCs and alleviates colitis.

This knowledge gap prompted our study of the microbial ecology and amine formation in marinated and unmarinated modified atmosphere commercially packaged rainbow trout fillet strips. According to our findings, marination increased the maximum concentrations (7-8 log CFU/g) of psychrotrophic bacteria by one logarithmic unit and led to 5 times higher average tyramine concentrations than the corresponding unmarinated product. Instead, trimethylamine concentrations were 30 times higher in the unmarinated product than those in the marinated one. According to the 16 S rRNA sequence analyses, lactic acid bacteria (LAB) predominated in the marinated strips one day after the use-by date, whereas in the unmarinated strips Fusobacteriaceae and LAB were the dominating taxa. Based on the culture-dependent analysis, Latilactobacillus fuchuensis was the prevailing LAB in both products. Since the subset of L. fuchuensis strains tested was able to produce tyramine in vitro, we hypothesise that the use of the acidic marinade activated the production of tyrosine-decarboxylating enzymes in L. fuchuensis and led to the increased tyramine concentrations."},{"quadrant":"Run1_Eval1_synthesis","attempt":1,"quote":"The contents of histamine, spermidine, spermine and tyramine of muscle were decreased with the VLP diet compared to the NP diet (P < 0.05).","status":"PASS","error":"","abstract_text":"ID: 36178065\nTitle: Effects of low protein diet with a balanced amino acid pattern on growth performance, meat quality and cecal microflora of finishing pigs.\nAbstract: The present study aimed to investigate the effects of low protein diets balanced with four amino acids on growth performance, meat quality and cecal microflora of finishing pigs.

Sulfotransferases catalyze these reactions by transferring a sulfo group from a donor to an acceptor molecule. Human cytosolic sulfotransferases use only 3'-phosphoadenosine 5'-phosphosulfate (PAPS) as a donor to sulfonate a variety of chemicals. Less understood are microbial aryl-sulfate sulfotransferases (ASSTs), which catalyze sulfo transfer reactions, without utilizing PAPS as a donor. Currently, the identity of physiological sulfo donor substrates remains unknown and sulfo acceptor substrates are underexplored. With this study, we aim to understand the potential contribution of a gut microbial enzyme to sulfonation chemistry by uncovering its substrate preferences.

This review explores the distribution, biochemical diversity, and host interactions of microbiota-encoded AADCs, highlighting their roles in gut and skin ecosystems. Bacterial AADCs vary in gene organization, substrate range, and expression patterns across taxa like Ruminococcus gnavus, Clostridium sporogenes, Enterococcus spp., and Staphylococcus spp. These enzymes contribute to microbial fitness through acid stress resistance, energy generation via proton motive force, epithelial adherence and internalization, and niche dominance. Critically, their products modulate host physiology via trace amine-associated receptors (TAARs) and other signaling pathways, influencing neurotransmission, immune response, barrier integrity, and metabolism. Microbiota-derived monoamines can enter systemic circulation and cross the blood-brain barrier, implicating them in disorders ranging from irritable bowel syndrome to neurodegeneration. Emerging data also reveal their impact on wound healing and drug efficacy, notably in Parkinson's disease.

Nevertheless, the conventional surgical castration procedure poses several challenges, including heightened stress and pain, detrimental impacts on animal welfare, and diminished economic efficacy in farming operations. Consequently, immunocastration methods, serving as substitutes for surgical castration, are progressively finding application in livestock. The rumen, an essential and distinctive digestive and absorptive organ in ruminants, has been associated with enhanced meat quality and productive performance following castration in previous research studies, albeit fewer investigations have explored the potential impacts of GnRH immunization on the rumen's internal milieu in sheep post-de-escalation. Hence, the present study delved into evaluating the impact of GnRH immunocastration on the rumen microbiome and metabolomics in male Xizang sheep. This was achieved through the establishment of a GnRH immunocastration animal model and the collection of rumen fluid for microbiological and comprehensive metabolomics investigations. The outcomes of this investigation unveiled that the impact of GnRH immunocastration on body weight gain was more pronounced during the achievement of the castration objective. In addition, the Firmicutes-to-Bacteroidota ratio in the immune male (IM) group exceeded that of the control group (EM), suggesting that GnRH immunodeficiency may enhance the digestion and absorption of feed in male Xizang sheep. At the taxonomic level, the elevated presence of Prevotella and Quinella bacteria in the IM group compared to the EM group indicated that castration influenced a segment of the rumen microbiota in male Xizang sheep, thereby bolstering the digestive and metabolic efficacy of the rumen concerning nutrient utilization, particularly in the breakdown and absorption of proteins, carbohydrates, and lipids, ultimately expediting the fattening process and weight gain in male Xizang sheep following castration. Moreover, analysis of ruminal fluid metabolomics revealed that GnRH immunization had notable impacts on certain metabolites in the ruminal fluid of male Xizang sheep, with metabolites like 5-hydroxyindole acetic acid and 3-hydroxyindole acetic acid showing significant downregulation in the IM group compared to the EM group, while niacin and tyramine exhibited significant upregulation. These findings indicate a profound influence of GnRH immunization on the maintenance of ruminal equilibrium and ruminal health (including the health of ruminal epithelial cells). This study validates that GnRH immunocastration not only achieves the objectives of castration but also enhances ruminal health in male Xizang sheep, thus laying a foundational theoretical basis for the application and dissemination of GnRH immunocastration technology."},{"quadrant":"Run1_Eval1_synthesis","attempt":1,"quote":"Supplement bars provided 20, 5, or 0 g/d of hemp hull powder. ...

In this study, we aimed to explore the role of gut microbial tyramine in intestinal damage and MASLD development in children. We investigated the functions and mechanisms of previously isolated Enterococcus faecium B6 (E. faecium B6) and its derived tyramine in a mice model of intestinal injury and MASLD development. An integrative analysis of transcriptomics and proteomics was performed on mouse liver to explore the molecular mechanisms of tyramine in MASLD progression. Targeted metabolomics was performed using fecal samples from a hospital-based population (27 MASLD cases and 27 matched controls) to measure tyramine levels. The association of serum tyramine and MASLD risk was then validated in a school-based population, using serum samples of 294 children in the MASLD group and 235 controls. E. faecium B6 and its metabolite tyramine significantly disrupted the intestinal barrier and increased intestinal permeability in mice. Tyramine supplementation promoted MASLD-related metabolic phenotype in mice. Multi-omics analysis indicated that the PPAR signaling pathway played an important role in the molecular mechanisms. Tyramine contributed to lipid accumulation mainly by increasing lipid synthesis and lipid uptake but reducing the β-oxidation processes in the mouse liver, as shown by real-time quantitative polymerase chain reaction and western blot. Furthermore, we demonstrated from the hospital-based cohort that tyramine concentration was significantly higher in the MASLD group than in the control group. Consistently, the school-based cohort demonstrated a higher risk of MASLD in the high-tyramine group compared to the low-tyramine group, with adjusted odds ratios (ORs) and 95% confidence intervals (CIs) of 3.65 (95% CI: 2.66-4.32).

Dietary intervention with squid-derived CS significantly attenuated characteristic UC symptoms, including body weight loss, colon shortening, and histopathological damage. Mechanistic analyses revealed that squid-derived CS exerted potent anti-inflammatory effects by downregulating key pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) and alleviated oxidative stress by enhancing colonic antioxidant capacity, as evidenced by increased activities of catalase (CAT) and superoxide dismutase (SOD) and reduced myeloperoxidase (MPO) activity. Integrated 16S rRNA gene sequencing and metabolomics analyses demonstrated that squid-derived CS profoundly restructured gut microbial community composition by enriching putative beneficial bacteria (e.g., Bifidobacterium, Clostridium, Blautia) while reducing opportunistic pathogens (e.g., Enterococcus, Sutterellaceae, Clostridia_UCG-014). This favorable microbial shift was accompanied by a reconfiguration of the intestinal metabolome, characterized by elevated production of beneficial short-chain fatty acids (SCFAs) and decreased levels of pro-inflammatory metabolites such as tyramine. Furthermore, squid-derived CS effectively enhanced intestinal barrier integrity by upregulating key tight junction proteins (ZO-1, occludin, claudin-1), thereby preventing bacterial lipopolysaccharide (LPS) translocation and associated liver injury, as indicated by reduced serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Collectively, these findings demonstrate that dietary squid-derived CS protects against UC by modulating gut microbiota composition to enrich beneficial taxa, restoring microbial metabolite homeostasis, reinforcing the intestinal epithelial barrier, and suppressing inflammatory responses and oxidative stress. This study provides the first evidence that squid-derived CS acts as a novel and promising marine prebiotic candidate for gut health promotion, highlighting its potential as a sustainable functional ingredient derived from processing waste for gut-health-promoting foods."},{"quadrant":"Run1_Eval1_synthesis","attempt":2,"quote":"Enterococcus-derived tyramine suppresses ISC proliferation, thereby impairing epithelial regeneration and exacerbating DSS-induced colitis through ADRA2A.","status":"PASS","error":"","abstract_text":"ID: 38788722\nTitle: Enterococcus-derived tyramine hijacks α2A-adrenergic receptor in intestinal stem cells to exacerbate colitis.\nAbstract: Inflammatory bowel disease (IBD) is characterized by dysbiosis of the gut microbiota and dysfunction of intestinal stem cells (ISCs).

Sulfotransferases catalyze these reactions by transferring a sulfo group from a donor to an acceptor molecule. Human cytosolic sulfotransferases use only 3'-phosphoadenosine 5'-phosphosulfate (PAPS) as a donor to sulfonate a variety of chemicals.

Currently, the identity of physiological sulfo donor substrates remains unknown and sulfo acceptor substrates are underexplored.

Nevertheless, the conventional surgical castration procedure poses several challenges, including heightened stress and pain, detrimental impacts on animal welfare, and diminished economic efficacy in farming operations. Consequently, immunocastration methods, serving as substitutes for surgical castration, are progressively finding application in livestock. The rumen, an essential and distinctive digestive and absorptive organ in ruminants, has been associated with enhanced meat quality and productive performance following castration in previous research studies, albeit fewer investigations have explored the potential impacts of GnRH immunization on the rumen's internal milieu in sheep post-de-escalation. Hence, the present study delved into evaluating the impact of GnRH immunocastration on the rumen microbiome and metabolomics in male Xizang sheep. This was achieved through the establishment of a GnRH immunocastration animal model and the collection of rumen fluid for microbiological and comprehensive metabolomics investigations. The outcomes of this investigation unveiled that the impact of GnRH immunocastration on body weight gain was more pronounced during the achievement of the castration objective. In addition, the Firmicutes-to-Bacteroidota ratio in the immune male (IM) group exceeded that of the control group (EM), suggesting that GnRH immunodeficiency may enhance the digestion and absorption of feed in male Xizang sheep. At the taxonomic level, the elevated presence of Prevotella and Quinella bacteria in the IM group compared to the EM group indicated that castration influenced a segment of the rumen microbiota in male Xizang sheep, thereby bolstering the digestive and metabolic efficacy of the rumen concerning nutrient utilization, particularly in the breakdown and absorption of proteins, carbohydrates, and lipids, ultimately expediting the fattening process and weight gain in male Xizang sheep following castration. Moreover, analysis of ruminal fluid metabolomics revealed that GnRH immunization had notable impacts on certain metabolites in the ruminal fluid of male Xizang sheep, with metabolites like 5-hydroxyindole acetic acid and 3-hydroxyindole acetic acid showing significant downregulation in the IM group compared to the EM group, while niacin and tyramine exhibited significant upregulation. These findings indicate a profound influence of GnRH immunization on the maintenance of ruminal equilibrium and ruminal health (including the health of ruminal epithelial cells). This study validates that GnRH immunocastration not only achieves the objectives of castration but also enhances ruminal health in male Xizang sheep, thus laying a foundational theoretical basis for the application and dissemination of GnRH immunocastration technology."},{"quadrant":"Run1_Eval1_synthesis","attempt":2,"quote":"metabolomic analysis showed that differential metabolites were enriched in the neuroactive ligand-receptor interaction pathway, in which GABA (γ-aminobutyric acid), histamine and tyramine metabolites were positively correlated with the above species and police performance.","status":"PASS","error":"","abstract_text":"ID: 41840712\nTitle: Characterization of age-related changes in the gut microbiome and metabolome of Kunming dogs and their associations with police performance.\nAbstract: Gut microbiota plays a pivotal role in regulating the host's central nervous system (CNS) activity and behavior.

Here, we found that dysbiosis-induced tyramine (TA) suppresses high-fat diet (HFD)-mediated insulin resistance in both Drosophila and mice. In Drosophila, HFD increases cytosolic Ca2+ signaling in enterocytes, which, in turn, suppresses intestinal lipid levels. 16 S rRNA sequencing and metabolomics revealed that HFD leads to increased prevalence of tyrosine decarboxylase (Tdc)-expressing bacteria and resulting tyramine production. Tyramine acts on the tyramine receptor, TyrR1, to promote cytosolic Ca2+ signaling and activation of the CRTC-CREB complex to transcriptionally suppress dietary lipid digestion and lipogenesis in enterocytes, while promoting mitochondrial biogenesis.

NAFLD is usually linked to obesity and excessive weight. A subset of patients with NAFLD expresses normal or low body mass index; thus, the condition is called non-obese NAFLD or lean NAFLD. However, patients and healthcare professionals have little awareness and understanding of NAFLD in non-obese individuals. Furthermore, preclinical results from non-obese animal models with NAFLD are unclear. Gut microbiota and their metabolites in non-obese/lean-NAFLD patients differ from those in obese NAFLD patients. Therefore, we analyzed the biochemical indices, intestinal flora, and intestinal metabolites in a non-obese NAFLD mouse model established using a methionine-choline-deficient (MCD) diet. The significantly lean MCD mice had a remarkable fatty liver with lower serum triglyceride and free fatty acid levels, as well as higher alanine transaminase and aspartate transaminase levels than normal mice. 16S RNA sequencing of fecal DNA showed that the overall richness and diversity of the intestinal flora decreased in MCD mice, whereas the Firmicutes:Bacteroidota ratio was increased. g_Tuzzerella, s_Bifidobacterium pseudolongum, and s_Faecalibaculum rodentium were the predominant species in non-obese NAFLD mice. Fecal metabolomics using liquid chromatography-tandem mass spectrometry revealed the potential biomarkers for the prognosis and diagnosis of non-obese NAFLD, including high levels of tyramine glucuronide, 9,12,13-TriHOME, and pantetheine 4'-phosphate, and low levels of 3-carbamoyl-2-phenylpropionaldehyde, N-succinyl-L,L-2,6-diaminopimelate, 4-methyl-5-thiazoleethanol, homogentisic acid, and estriol. Our findings could be useful to identify and develop drugs to treat non-obese NAFLD and lean NAFLD. Patients and healthcare professionals have little awareness and understanding of NAFLD in non-obese individuals. In fact, about 40% of people with NAFLD worldwide are non-obese, and nearly one-fifth are lean. Lean NAFLD unfortunately may be unnoticed for years and remains undetected until hepatic damage is advanced and the prognosis is compromised. This study focused on the lean NAFLD, screened therapeutic agents, and biomarkers for the prognosis and diagnosis using MCD-induced male C57BL/6J mice.

Roux-en-Y gastric bypass (RYGB) has been associated with increased long-term CRC risk (HR 1.55 at 10-14 years), whereas sleeve gastrectomy (SG) shows no equivalent elevation, though shorter follow-up (mean 4.5 vs. 8.5 years) precludes definitive conclusions. This review develops a biologically plausible mechanistic framework for these divergent outcomes. RYGB-induced anatomical bypass and accelerated transit are proposed to drive distal substrate overload, with an associated shift of the colonic microbiome toward proteolytic fermentation. The proposed genotoxic luminal environment is characterized by convergent actions of secondary bile acids, tyramine, and hydrogen sulfide, compounded by butyrate depletion.

Dietary intervention with squid-derived CS significantly attenuated characteristic UC symptoms, including body weight loss, colon shortening, and histopathological damage. Mechanistic analyses revealed that squid-derived CS exerted potent anti-inflammatory effects by downregulating key pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) and alleviated oxidative stress by enhancing colonic antioxidant capacity, as evidenced by increased activities of catalase (CAT) and superoxide dismutase (SOD) and reduced myeloperoxidase (MPO) activity. Integrated 16S rRNA gene sequencing and metabolomics analyses demonstrated that squid-derived CS profoundly restructured gut microbial community composition by enriching putative beneficial bacteria (e.g., Bifidobacterium, Clostridium, Blautia) while reducing opportunistic pathogens (e.g., Enterococcus, Sutterellaceae, Clostridia_UCG-014). This favorable microbial shift was accompanied by a reconfiguration of the intestinal metabolome, characterized by elevated production of beneficial short-chain fatty acids (SCFAs) and decreased levels of pro-inflammatory metabolites such as tyramine. Furthermore, squid-derived CS effectively enhanced intestinal barrier integrity by upregulating key tight junction proteins (ZO-1, occludin, claudin-1), thereby preventing bacterial lipopolysaccharide (LPS) translocation and associated liver injury, as indicated by reduced serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Collectively, these findings demonstrate that dietary squid-derived CS protects against UC by modulating gut microbiota composition to enrich beneficial taxa, restoring microbial metabolite homeostasis, reinforcing the intestinal epithelial barrier, and suppressing inflammatory responses and oxidative stress.

The microbial species within a microbiome, on the one hand, compete for resources, while on the other hand, they exchange vital metabolites to support their survival. These interactions are influenced by the microbial genetic repertoire, environmental conditions, and availability of nutrients. We developed EcoGS (http://www.github.com/KaletaLab/EcoGS), a metabolic modeling tool designed to predict the ecological interactions between pairs of microbes. Applying EcoGS to the microbiomes of two distinct human cohorts revealed a shift from collaborative to exploitative ecological interactions associated with increased dietary intake of simple sugars (glucose and fructose) in diabetic individuals and those living industrialized lifestyles. On the other hand, the consumption of cobalamin (vitamin B12), phylloquinone (vitamin K1), and biotin (vitamin B7), among other compounds, was associated with increased collaboration in the gut microbiome. We conclude that the abundance of simple sugars as an energy source reduces the necessity for microbes to cooperate, thereby increasing competition and hostility among microbiome members. Moreover, our study proposes multiple compounds, such as urate, deoxyadenosine, deoxyguanosine, and hypoxanthine, for in vitro validation tests as dietary interventions that have the potential to restore the ecological balance within the community.

During dairy fermentation, these microorganisms generate bioactive compounds, such as bioactive peptides, exopolysaccharides, organic acids and other metabolites, which may contribute to host health. There is emerging evidence that fermented dairy products can influence gastrointestinal function, immune regulation, metabolic health and cardiovascular risk, via mechanisms involving modulation of the gut microbiota, stabilisation of the epithelial barrier and inflammatory signalling pathways. In addition, fermentation may improve lactose digestion, enhance nutrient bioavailability, and generate peptides with anti-hypertensive or antioxidant properties. However, translating these results into consistent health benefits is challenging due to the significant variability in microbial strains, product composition, processing conditions and dosage. Safety considerations such as biogenic amines, sodium content, allergenicity and antimicrobial resistance also require careful monitoring. Future progress in this field will depend on improved product characterisation, strain-level identification and well-designed human intervention studies that integrate multi-omics approaches.

This review outlines their activation of the brainstem's area postrema (AP) via intestinal barrier disruption, dysbiosis, vagus nerve stimulation, or direct central penetration. Acute exposure induces anorexia/defense responses through AP/NTS receptor pathways (GLP-1R, CCK, PYY, ghrelin, GDF15-GFRAL, 5-HT3). Chronic exposure impairs the AP-hypothalamus-locus coeruleus (LC) pathway, causing neuropsychiatric disorders, cachexia-like metabolic reprogramming, and multi-organ dysfunction. The gut microbiota play pivotal roles in toxin metabolism, bioactivation, and detoxification; microbial dysbiosis and LPS translocation amplify systemic inflammation. The elderly, immunocompromised individuals, and patients with comorbidities are particularly vulnerable due to weakened barriers, immunosenescence, and polypharmacy.

Three strains showing high protease activity (> 90.00 U/mL) and low BA levels (< 40 mg/kg) were isolated from naturally fermented douchi: A1 Bacillus velezensis, A2 B. glycinifermentans, and A3 B. subtilis. A1, with the lowest total biogenic amine (TBA) levels, was selected as the representative strain. The optimal fermentation conditions (8% inoculum, 37°C temperature, 3 days duration) reduced TBA to levels well below the FDA standard (< 1000 mg/kg). Compared to the natural fermentation (NF), it was verified that the TBA of douchi was lowered to 10.51 ± 0.21 mg/kg after optimized fermentation, approximately reduced 10.80-fold. Spermine levels decreased by 43.17-fold, followed by tyramine and phenethylamine. Further, apply them to large-scale cultivation (scaled up by 100-fold) in actual production during colony-enhanced fermentation (CEF). The physicochemical properties and BA levels were monitored to assess the correlation. The findings showed that the douchi of CEF had up to 0.94% amino acid nitrogen (≥ 0.25% EN) and 0.72% total acid (≤ 2.5% EN). The TBA level was only 38.27 ± 0.13 mg/kg, significantly lower than NF (94.94 ± 2.59 mg/kg).

This approach significantly reduced the TBA levels in bacteria-type douchi, offering a crucial reference for the industrial-scale safe production of fermented soybean products. PRACTICAL APPLICATIONS: This research offers industrial-level guidance for douchi production. By utilizing Bacillus velezensis A1 and optimizing the process, the TBA can be reduced by a factor of 2.5 while maintaining product quality (T/GZSX 014-2018).

Our study aims to investigate associations between central obesity replacement indices, dietary intake of sugar and lipids, and OAB risk using National Health and Nutrition Examination Survey 2005-2016 data. Cross-sectional study. This study analyzed 24,675 adults (4848 OAB cases). Weight, body mass index, and other central obesity replacement indices (waist circumference, weight-adjusted waist index, waist-to-height ratio (WHtR), body roundness index (BRI)) and dietary nutrients intake (carbohydrate, sugars, fat, saturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids (PUFAs), and cholesterol) were assessed. Propensity score matching (1:2) balanced covariates. Multivariable logistic regression and generalized additive models evaluated dose-response relationships. All central obesity indices showed significant positive associations with OAB (p < 0.001), with WHtR and BRI demonstrating the strongest effects (adjusted odds ratio (OR) = 2.04, 95% confidence interval: 1.80-2.30). Nonlinear relationships were observed, particularly for WHtR (degrees of freedom = 3.30-6.16). Dietary analysis revealed that OAB patients had significantly higher consumption of total energy, carbohydrates, and sugars (all p < 0.05), and higher sugar intake increased OAB risk (OR = 1.32, p = 0.0016), while PUFAs were protective (OR = 0.79, p = 0.0159). Central obesity replacement indices, especially WHtR and BRI, strongly predict OAB risk.

Metabolomic profiling of fecal microbial extracellular vesicles (EVs) offers a promising yet underexplored avenue for biomarker discovery when integrated with explainable machine learning (ML) frameworks. This study aimed to identify stool-derived microbial EV metabolite biomarkers that discriminate CRC patients from healthy controls and to develop interpretable ML classifiers for non-invasive CRC detection. Metabolomic profiles of fecal microbial EVs from 76 age- and sex-comparable participants (36 CRC, 40 controls) were obtained using LC/QTOFMS and GC/TOFMS. Three ML classifiers (TPOT, LightGBM, XGBoost) were trained and evaluated through 100-repeat stratified hold-out and nested 5-fold cross-validation, with SHAP and LIME applied for global and local interpretability. Fourteen metabolites were significantly dysregulated between the CRC and control groups (adjusted p < 0.05), with 13 upregulated and one (aminoisobutyric acid) downregulated. Furoic acid exhibited perfect diagnostic discrimination, followed by palmitic acid and tyramine. Nested cross-validation demonstrated robust performance: TPOT achieved AUC = 0.997 ± 0.005, sensitivity = 0.973 ± 0.022, and MCC = 0.957 ± 0.033. Hold-out validation corroborated these findings (AUC = 0.998 ± 0.008). SHAP analysis identified furoic acid, palmitic acid, and tyramine as the dominant predictive features, while aminoisobutyric acid exhibited a distinctive protective pattern. LIME analysis corroborated these findings at the individual prediction level. The identified fecal EV-derived metabolite panel-particularly furoic acid, palmitic acid, and tyramine-shows strong potential to predict CRC in a non-invasive, interpretable manner; however, given the modest sample size, these findings should be considered hypothesis-generating and require validation in larger, prospective, multi-center cohorts before clinical translation."},{"quadrant":"Run2_Eval1_synthesis","attempt":1,"quote":"Tyrosine decarboxylases (TyDCs) are pyridoxal 5'-phosphate-dependent enzymes that catalyze the conversion of l-tyrosine into tyramine, a key entry point for Amaryllidaceae alkaloid biosynthesis.","status":"PASS","error":"","abstract_text":"ID: 42409273\nTitle: Molecular cloning and functional characterization of tyrosine decarboxylase genes from galanthamine-producing Narcissus pseudonarcissus 'King Alfred.'.\nAbstract: Tyrosine decarboxylases (TyDCs) are pyridoxal 5'-phosphate-dependent enzymes that catalyze the conversion of l-tyrosine into tyramine, a key entry point for Amaryllidaceae alkaloid biosynthesis.

Phosphate binders are standard treatment for hyperphosphatemia but may influence gut microbiota by altering luminal pH, intestinal transit, and availability of metabolites such as SCFAs and vitamin K. These changes can impair gut barrier integrity and promote inflammation. Evidence on their microbiome effects is mixed: some studies show minimal compositional changes with calcium acetate or sucroferric oxyhydroxide, while others report individual variability and subtle taxon-specific shifts, particularly with iron-based binders. Even when compositional changes are limited, certain binders may modulate uremic toxin levels. Given the limitations of conventional therapies, biological approaches such as probiotics, synbiotics, and phosphate-accumulating organisms (PAOs) are gaining interest. These strategies may reduce intestinal phosphate availability by lowering pH, enhancing calcium-phosphate binding, and promoting microbial phosphate uptake and storage, while supporting gut barrier function. Overall, current evidence remains heterogeneous and limited by small cohorts and preclinical designs. Although microbiota-targeted therapies show mechanistic promise, robust clinical trials are needed before they can be recommended beyond adjunctive use."},{"quadrant":"Run2_Eval1_synthesis","attempt":2,"quote":"The proposed genotoxic luminal environment is characterized by convergent actions of secondary bile acids, tyramine, and hydrogen sulfide, compounded by butyrate depletion.","status":"PASS","error":"","abstract_text":"ID: 42283770\nTitle: Divergent Colorectal Cancer Risks Following Metabolic Bariatric Surgery: Anatomical Remodeling and the Genotoxic Microenvironment.\nAbstract: Metabolic bariatric surgery (MBS) reduces overall cancer incidence, yet colorectal cancer (CRC) risk diverges by procedure. Roux-en-Y gastric bypass (RYGB) has been associated with increased long-term CRC risk (HR 1.55 at 10-14 years), whereas sleeve gastrectomy (SG) shows no equivalent elevation, though shorter follow-up (mean 4.5 vs. 8.5 years) precludes definitive conclusions.

RYGB-induced anatomical bypass and accelerated transit are proposed to drive distal substrate overload, with an associated shift of the colonic microbiome toward proteolytic fermentation. The proposed genotoxic luminal environment is characterized by convergent actions of secondary bile acids, tyramine, and hydrogen sulfide, compounded by butyrate depletion.

Dietary intervention with squid-derived CS significantly attenuated characteristic UC symptoms, including body weight loss, colon shortening, and histopathological damage. Mechanistic analyses revealed that squid-derived CS exerted potent anti-inflammatory effects by downregulating key pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) and alleviated oxidative stress by enhancing colonic antioxidant capacity, as evidenced by increased activities of catalase (CAT) and superoxide dismutase (SOD) and reduced myeloperoxidase (MPO) activity. Integrated 16S rRNA gene sequencing and metabolomics analyses demonstrated that squid-derived CS profoundly restructured gut microbial community composition by enriching putative beneficial bacteria (e.g., Bifidobacterium, Clostridium, Blautia) while reducing opportunistic pathogens (e.g., Enterococcus, Sutterellaceae, Clostridia_UCG-014). This favorable microbial shift was accompanied by a reconfiguration of the intestinal metabolome, characterized by elevated production of beneficial short-chain fatty acids (SCFAs) and decreased levels of pro-inflammatory metabolites such as tyramine. Furthermore, squid-derived CS effectively enhanced intestinal barrier integrity by upregulating key tight junction proteins (ZO-1, occludin, claudin-1), thereby preventing bacterial lipopolysaccharide (LPS) translocation and associated liver injury, as indicated by reduced serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Collectively, these findings demonstrate that dietary squid-derived CS protects against UC by modulating gut microbiota composition to enrich beneficial taxa, restoring microbial metabolite homeostasis, reinforcing the intestinal epithelial barrier, and suppressing inflammatory responses and oxidative stress.

Three strains showing high protease activity (> 90.00 U/mL) and low BA levels (< 40 mg/kg) were isolated from naturally fermented douchi: A1 Bacillus velezensis, A2 B. glycinifermentans, and A3 B. subtilis. A1, with the lowest total biogenic amine (TBA) levels, was selected as the representative strain. The optimal fermentation conditions (8% inoculum, 37°C temperature, 3 days duration) reduced TBA to levels well below the FDA standard (< 1000 mg/kg). Compared to the natural fermentation (NF), it was verified that the TBA of douchi was lowered to 10.51 ± 0.21 mg/kg after optimized fermentation, approximately reduced 10.80-fold. Spermine levels decreased by 43.17-fold, followed by tyramine and phenethylamine. Further, apply them to large-scale cultivation (scaled up by 100-fold) in actual production during colony-enhanced fermentation (CEF). The physicochemical properties and BA levels were monitored to assess the correlation. The findings showed that the douchi of CEF had up to 0.94% amino acid nitrogen (≥ 0.25% EN) and 0.72% total acid (≤ 2.5% EN). The TBA level was only 38.27 ± 0.13 mg/kg, significantly lower than NF (94.94 ± 2.59 mg/kg).

Our study aims to investigate associations between central obesity replacement indices, dietary intake of sugar and lipids, and OAB risk using National Health and Nutrition Examination Survey 2005-2016 data. Cross-sectional study. This study analyzed 24,675 adults (4848 OAB cases). Weight, body mass index, and other central obesity replacement indices (waist circumference, weight-adjusted waist index, waist-to-height ratio (WHtR), body roundness index (BRI)) and dietary nutrients intake (carbohydrate, sugars, fat, saturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids (PUFAs), and cholesterol) were assessed. Propensity score matching (1:2) balanced covariates. Multivariable logistic regression and generalized additive models evaluated dose-response relationships. All central obesity indices showed significant positive associations with OAB (p < 0.001), with WHtR and BRI demonstrating the strongest effects (adjusted odds ratio (OR) = 2.04, 95% confidence interval: 1.80-2.30). Nonlinear relationships were observed, particularly for WHtR (degrees of freedom = 3.30-6.16). Dietary analysis revealed that OAB patients had significantly higher consumption of total energy, carbohydrates, and sugars (all p < 0.05), and higher sugar intake increased OAB risk (OR = 1.32, p = 0.0016), while PUFAs were protective (OR = 0.79, p = 0.0159). Central obesity replacement indices, especially WHtR and BRI, strongly predict OAB risk. Dietary modifications, including reducing sugars and increasing PUFAs intake, may complement abdominal fat reduction for OAB prevention. These findings highlight the importance of combined weight management and dietary modifications for OAB prevention in high-risk populations. Can the fats we eat and belly fat affect bladder health? Overactive bladder (OAB) can seriously affect daily life. Using data from over 24,000 U.S. adults, this study found that people with more belly fat were more likely to have OAB, especially when their waist-to-height ratio and body roundness index were high. Diet also mattered—those who ate more sugars had higher OAB risk, while consuming more healthy fats, such as polyunsaturated fatty acids (PUFAs), was linked to lower risk.

Metabolomic profiling of fecal microbial extracellular vesicles (EVs) offers a promising yet underexplored avenue for biomarker discovery when integrated with explainable machine learning (ML) frameworks. This study aimed to identify stool-derived microbial EV metabolite biomarkers that discriminate CRC patients from healthy controls and to develop interpretable ML classifiers for non-invasive CRC detection. Metabolomic profiles of fecal microbial EVs from 76 age- and sex-comparable participants (36 CRC, 40 controls) were obtained using LC/QTOFMS and GC/TOFMS. Three ML classifiers (TPOT, LightGBM, XGBoost) were trained and evaluated through 100-repeat stratified hold-out and nested 5-fold cross-validation, with SHAP and LIME applied for global and local interpretability. Fourteen metabolites were significantly dysregulated between the CRC and control groups (adjusted p < 0.05), with 13 upregulated and one (aminoisobutyric acid) downregulated. Furoic acid exhibited perfect diagnostic discrimination, followed by palmitic acid and tyramine.

Sulfotransferases catalyze these reactions by transferring a sulfo group from a donor to an acceptor molecule. Human cytosolic sulfotransferases use only 3'-phosphoadenosine 5'-phosphosulfate (PAPS) as a donor to sulfonate a variety of chemicals. Less understood are microbial aryl-sulfate sulfotransferases (ASSTs), which catalyze sulfo transfer reactions, without utilizing PAPS as a donor. Currently, the identity of physiological sulfo donor substrates remains unknown and sulfo acceptor substrates are underexplored. With this study, we aim to understand the potential contribution of a gut microbial enzyme to sulfonation chemistry by uncovering its substrate preferences. Here, we show that a sulfotransferase (Bacteroides vulgatus ASST) from the prevalent gut microbe B. vulgatus (now Phocaeicola vulgatus) is a versatile catalyst that utilizes a wide range of phenolic molecules as substrates that are commonly encountered by the host.

Our study identified elevated fecal trace amine levels in ulcerative colitis (UC) patients and DSS-induced colitis mice.

In vivo, EPPTB treatment significantly mitigated DSS-induced colitis, as demonstrated by reduced weight loss, improved disease activity index (DAI), preserved colon length, and attenuated histopathological damage. Moreover, TAAR1 blockade reduced pro-inflammatory cytokines (TNF-α, IL-6, IL-1β) and increased IκB-α expression, restored intestinal barrier integrity (upregulating occludin and ZO-1, while downregulating cclaudin-2), and lowered colonic 5-HT levels by suppressing TPH1 expression.

The study examined the prevalence of food taboos, tabooed foods and explored reasons for their existence among different segments of Puntland communities. A community based mixed methods cross-sectional study was conducted between September and December across the nine regions of Puntland state of Somalia. A total of 290 participants were selected using multi-stage sampling. Quantitative data were collected using structured questionnaires while qualitative data were obtained through 18 key informant interviews and 37 Focus Group Discussions (FGDs) involving pregnant and lactating women, elderly men and women, women of reproductive age and adult men. Data on demographic characteristics were analyzed using SPSS version 31, while qualitative data were analyzed thematically using systematic text condensation. Overall, 88% of participants reported the existence of food taboos in their communities. Pregnancy and lactation were the life stages with the most restrictions (32%) and the least were during menstruation (12%). Commonly tabooed foods during pregnancy included honey, ghee, sheep meat, chili, papaya and whole grains primarily due to beliefs linking them to miscarriage, fetal deformities and labor complications. Liver was universally restricted for children under two years due to perceived speech delay. Men also faced prohibitions such organ meats except liver, animal head, neck and leg meat, considered foods for females and associated with shame, weakness and cowardice. Regional variations were observed with certain taboos being specific to regions, mostly Mudug and Eyl district of Nugaal region. Food taboos are common throughout Puntland but they are more rampant in Mudug region and Eyl district of Nugaal region.

Dietary intervention with squid-derived CS significantly attenuated characteristic UC symptoms, including body weight loss, colon shortening, and histopathological damage. Mechanistic analyses revealed that squid-derived CS exerted potent anti-inflammatory effects by downregulating key pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) and alleviated oxidative stress by enhancing colonic antioxidant capacity, as evidenced by increased activities of catalase (CAT) and superoxide dismutase (SOD) and reduced myeloperoxidase (MPO) activity. Integrated 16S rRNA gene sequencing and metabolomics analyses demonstrated that squid-derived CS profoundly restructured gut microbial community composition by enriching putative beneficial bacteria (e.g., Bifidobacterium, Clostridium, Blautia) while reducing opportunistic pathogens (e.g., Enterococcus, Sutterellaceae, Clostridia_UCG-014). This favorable microbial shift was accompanied by a reconfiguration of the intestinal metabolome, characterized by elevated production of beneficial short-chain fatty acids (SCFAs) and decreased levels of pro-inflammatory metabolites such as tyramine. Furthermore, squid-derived CS effectively enhanced intestinal barrier integrity by upregulating key tight junction proteins (ZO-1, occludin, claudin-1), thereby preventing bacterial lipopolysaccharide (LPS) translocation and associated liver injury, as indicated by reduced serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Collectively, these findings demonstrate that dietary squid-derived CS protects against UC by modulating gut microbiota composition to enrich beneficial taxa, restoring microbial metabolite homeostasis, reinforcing the intestinal epithelial barrier, and suppressing inflammatory responses and oxidative stress.

Three strains showing high protease activity (> 90.00 U/mL) and low BA levels (< 40 mg/kg) were isolated from naturally fermented douchi: A1 Bacillus velezensis, A2 B. glycinifermentans, and A3 B. subtilis. A1, with the lowest total biogenic amine (TBA) levels, was selected as the representative strain. The optimal fermentation conditions (8% inoculum, 37°C temperature, 3 days duration) reduced TBA to levels well below the FDA standard (< 1000 mg/kg). Compared to the natural fermentation (NF), it was verified that the TBA of douchi was lowered to 10.51 ± 0.21 mg/kg after optimized fermentation, approximately reduced 10.80-fold. Spermine levels decreased by 43.17-fold, followed by tyramine and phenethylamine. Further, apply them to large-scale cultivation (scaled up by 100-fold) in actual production during colony-enhanced fermentation (CEF). The physicochemical properties and BA levels were monitored to assess the correlation. The findings showed that the douchi of CEF had up to 0.94% amino acid nitrogen (≥ 0.25% EN) and 0.72% total acid (≤ 2.5% EN).

Our study aims to investigate associations between central obesity replacement indices, dietary intake of sugar and lipids, and OAB risk using National Health and Nutrition Examination Survey 2005-2016 data. Cross-sectional study. This study analyzed 24,675 adults (4848 OAB cases). Weight, body mass index, and other central obesity replacement indices (waist circumference, weight-adjusted waist index, waist-to-height ratio (WHtR), body roundness index (BRI)) and dietary nutrients intake (carbohydrate, sugars, fat, saturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids (PUFAs), and cholesterol) were assessed. Propensity score matching (1:2) balanced covariates. Multivariable logistic regression and generalized additive models evaluated dose-response relationships. All central obesity indices showed significant positive associations with OAB (p < 0.001), with WHtR and BRI demonstrating the strongest effects (adjusted odds ratio (OR) = 2.04, 95% confidence interval: 1.80-2.30). Nonlinear relationships were observed, particularly for WHtR (degrees of freedom = 3.30-6.16). Dietary analysis revealed that OAB patients had significantly higher consumption of total energy, carbohydrates, and sugars (all p < 0.05), and higher sugar intake increased OAB risk (OR = 1.32, p = 0.0016), while PUFAs were protective (OR = 0.79, p = 0.0159). Central obesity replacement indices, especially WHtR and BRI, strongly predict OAB risk. Dietary modifications, including reducing sugars and increasing PUFAs intake, may complement abdominal fat reduction for OAB prevention. These findings highlight the importance of combined weight management and dietary modifications for OAB prevention in high-risk populations. Can the fats we eat and belly fat affect bladder health? Overactive bladder (OAB) can seriously affect daily life. Using data from over 24,000 U.S. adults, this study found that people with more belly fat were more likely to have OAB, especially when their waist-to-height ratio and body roundness index were high.

Metabolomic profiling of fecal microbial extracellular vesicles (EVs) offers a promising yet underexplored avenue for biomarker discovery when integrated with explainable machine learning (ML) frameworks. This study aimed to identify stool-derived microbial EV metabolite biomarkers that discriminate CRC patients from healthy controls and to develop interpretable ML classifiers for non-invasive CRC detection. Metabolomic profiles of fecal microbial EVs from 76 age- and sex-comparable participants (36 CRC, 40 controls) were obtained using LC/QTOFMS and GC/TOFMS. Three ML classifiers (TPOT, LightGBM, XGBoost) were trained and evaluated through 100-repeat stratified hold-out and nested 5-fold cross-validation, with SHAP and LIME applied for global and local interpretability. Fourteen metabolites were significantly dysregulated between the CRC and control groups (adjusted p < 0.05), with 13 upregulated and one (aminoisobutyric acid) downregulated. Furoic acid exhibited perfect diagnostic discrimination, followed by palmitic acid and tyramine. Nested cross-validation demonstrated robust performance: TPOT achieved AUC = 0.997 ± 0.005, sensitivity = 0.973 ± 0.022, and MCC = 0.957 ± 0.033.

LIME analysis corroborated these findings at the individual prediction level. The identified fecal EV-derived metabolite panel-particularly furoic acid, palmitic acid, and tyramine-shows strong potential to predict CRC in a non-invasive, interpretable manner; however, given the modest sample size, these findings should be considered hypothesis-generating and require validation in larger, prospective, multi-center cohorts before clinical translation."},{"quadrant":"Run2_Eval1_synthesis","attempt":3,"quote":"The proposed sensing platform integrates the high conductivity of rGO, the electrocatalytic activity of Pt NPs, the TSA-derived Fc-Tyr deposition strategy, and the anti-interference properties of POPD.","status":"PASS","error":"","abstract_text":"ID: 42406127\nTitle: A non-enzymatic sensor based on rGO/Pt NPs/Fc-Tyr/POPD nanocomposite for hydrogen peroxide determination in liver cancer tissues.\nAbstract: Malignant tumors remain a major global health challenge, highlighting the need for rapid and sensitive analytical tools for investigating cancer-associated oxidative stress.

High-performing groups (MIX5, TM5) showed microbiomes enriched in short-chain fatty acid-producing bacteria (Veillonellaceae, Butyricicoccus, Limosilactobacillus crispatus), positively correlated with ADG and ADFI (FDR<0.05) and negatively correlated with FCR (FDR<0.05). Favorable metabolomic profiles (increased dopamine, tyramine, malic and orotic acids; reduced 3-deoxyglucosone, hexanoylcarnitine [FDR<0.05]) and preserved balance between neutral (positively correlated with BW and ADFI [P < 0.05]) and acidic mucins (positively correlated with BW, ADFI and ADG, and negatively correlated with FCR [P < 0.05]) were also observed. Low-performing groups (MIX10, HI10) displayed microbiomes dominated by Ruminococcaceae, Alistipes, and l-Eubacterium (negatively correlated with FCR and associated with purine metabolism alterations [FDR<0.05]), alongside worsened morphology (tendency for reduced villus height in MIX10 [P = 0.07], positively and negatively correlated with ADG and FCR, respectively [P < 0.05], and thinner mucosal/muscular layers [P < 0.05]) and decreased neutral mucins (P < 0.05). TM10 maintained unaffected growth performance via beneficial taxa (Limosilactobacillus crispatus, Tyzzerella), and reduced Campylobacter jejuni and antimicrobial resistance genes (FDR<0.05). Jejunal inflammation, negatively correlated with ADG (P < 0.05), was not influenced by dietary treatments (P > 0.05). In conclusion, specific taxa (Butyricicoccus, Veillonellaceae, Limosilactobacillus crispatus), metabolites (dopamine, tyramine, malic and orotic acids), and mucosal features (villus height, mucin composition) were identified as biomarkers of optimal performance in insect-fed broilers."},{"quadrant":"Run2_Eval1_synthesis","attempt":3,"quote":"Furthermore, metabolomic analysis showed that differential metabolites were enriched in the neuroactive ligand-receptor interaction pathway, in which GABA (γ-aminobutyric acid), histamine and tyramine metabolites were positively correlated with the above species and police performance.","status":"PASS","error":"","abstract_text":"ID: 41840712\nTitle: Characterization of age-related changes in the gut microbiome and metabolome of Kunming dogs and their associations with police performance.\nAbstract: Gut microbiota plays a pivotal role in regulating the host's central nervous system (CNS) activity and behavior. However, its influence on the police performance of Kunming dogs and the underlying mechanisms remain largely unexplored. This study was the first to apply multi-omics technologies to investigate the dynamic variations in gut microbiota and their metabolic profiles across different ages of Kunming dogs. Furthermore, we systematically examined the associations between these microbial alterations and police performance metrics, providing a theoretical foundation for enhancing the working capabilities of Kunming dogs through targeted modulation of intestinal microecology. The study showed that puppies, young dogs and adult dogs had significantly better police performance than elderly dogs, with young dogs exhibiting the highest scores. Analysis of 16S rRNA sequencing demonstrated that gut microbial diversity and stability were highest during the young dog stage, gradually declining with age. Metagenomic analysis revealed that the abundance of Lactobacillus acidophilus, Lactobacillus johnsonii, Limosilactobacillus reuteri, Ligilactobacillus animalis and Muribaculum gordoncarteri were strongly correlated with police performance. The results of metagenome-assembled genomes (MAGs) indicated that the above species have functional genes involved in GABAergic and glutamatergic synapse pathways. Furthermore, metabolomic analysis showed that differential metabolites were enriched in the neuroactive ligand-receptor interaction pathway, in which GABA (γ-aminobutyric acid), histamine and tyramine metabolites were positively correlated with the above species and police performance. The species L. acidophilus, L. johnsonii, L. reuteri, L. animalis, and M. gordoncarteri, which were enriched in the gut of puppies and young Kunming dogs, may potentially influence the nervous system through the production of neurotransmitters and neuromodulators, suggesting a possible association with police performance.

Sulfotransferases catalyze these reactions by transferring a sulfo group from a donor to an acceptor molecule. Human cytosolic sulfotransferases use only 3'-phosphoadenosine 5'-phosphosulfate (PAPS) as a donor to sulfonate a variety of chemicals. Less understood are microbial aryl-sulfate sulfotransferases (ASSTs), which catalyze sulfo transfer reactions, without utilizing PAPS as a donor. Currently, the identity of physiological sulfo donor substrates remains unknown and sulfo acceptor substrates are underexplored. With this study, we aim to understand the potential contribution of a gut microbial enzyme to sulfonation chemistry by uncovering its substrate preferences. Here, we show that a sulfotransferase (Bacteroides vulgatus ASST) from the prevalent gut microbe B. vulgatus (now Phocaeicola vulgatus) is a versatile catalyst that utilizes a wide range of phenolic molecules as substrates that are commonly encountered by the host. With this action, it modulates concentrations of donor phenolic sulfates such as acetaminophen sulfate, dopamine sulfate, p-cresol sulfate, and related compounds in vitro and displays broad acceptor flexibility by sulfonating diverse phenolic compounds, including p-coumaric acid, p-cresol, 4-ethylphenol, tyramine, among others.

In vivo, EPPTB treatment significantly mitigated DSS-induced colitis, as demonstrated by reduced weight loss, improved disease activity index (DAI), preserved colon length, and attenuated histopathological damage. Moreover, TAAR1 blockade reduced pro-inflammatory cytokines (TNF-α, IL-6, IL-1β) and increased IκB-α expression, restored intestinal barrier integrity (upregulating occludin and ZO-1, while downregulating cclaudin-2), and lowered colonic 5-HT levels by suppressing TPH1 expression.

The study examined the prevalence of food taboos, tabooed foods and explored reasons for their existence among different segments of Puntland communities. A community based mixed methods cross-sectional study was conducted between September and December across the nine regions of Puntland state of Somalia. A total of 290 participants were selected using multi-stage sampling. Quantitative data were collected using structured questionnaires while qualitative data were obtained through 18 key informant interviews and 37 Focus Group Discussions (FGDs) involving pregnant and lactating women, elderly men and women, women of reproductive age and adult men. Data on demographic characteristics were analyzed using SPSS version 31, while qualitative data were analyzed thematically using systematic text condensation. Overall, 88% of participants reported the existence of food taboos in their communities. Pregnancy and lactation were the life stages with the most restrictions (32%) and the least were during menstruation (12%). Commonly tabooed foods during pregnancy included honey, ghee, sheep meat, chili, papaya and whole grains primarily due to beliefs linking them to miscarriage, fetal deformities and labor complications. Liver was universally restricted for children under two years due to perceived speech delay. Men also faced prohibitions such organ meats except liver, animal head, neck and leg meat, considered foods for females and associated with shame, weakness and cowardice. Regional variations were observed with certain taboos being specific to regions, mostly Mudug and Eyl district of Nugaal region. Food taboos are common throughout Puntland but they are more rampant in Mudug region and Eyl district of Nugaal region. Some taboos reported during menstruation and illness have some scientific backup and may contribute to better management of these conditions.

Dietary intervention with squid-derived CS significantly attenuated characteristic UC symptoms, including body weight loss, colon shortening, and histopathological damage. Mechanistic analyses revealed that squid-derived CS exerted potent anti-inflammatory effects by downregulating key pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) and alleviated oxidative stress by enhancing colonic antioxidant capacity, as evidenced by increased activities of catalase (CAT) and superoxide dismutase (SOD) and reduced myeloperoxidase (MPO) activity. Integrated 16S rRNA gene sequencing and metabolomics analyses demonstrated that squid-derived CS profoundly restructured gut microbial community composition by enriching putative beneficial bacteria (e.g., Bifidobacterium, Clostridium, Blautia) while reducing opportunistic pathogens (e.g., Enterococcus, Sutterellaceae, Clostridia_UCG-014). This favorable microbial shift was accompanied by a reconfiguration of the intestinal metabolome, characterized by elevated production of beneficial short-chain fatty acids (SCFAs) and decreased levels of pro-inflammatory metabolites such as tyramine. Furthermore, squid-derived CS effectively enhanced intestinal barrier integrity by upregulating key tight junction proteins (ZO-1, occludin, claudin-1), thereby preventing bacterial lipopolysaccharide (LPS) translocation and associated liver injury, as indicated by reduced serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Collectively, these findings demonstrate that dietary squid-derived CS protects against UC by modulating gut microbiota composition to enrich beneficial taxa, restoring microbial metabolite homeostasis, reinforcing the intestinal epithelial barrier, and suppressing inflammatory responses and oxidative stress.

To understand the differential impact patterns of pectin vs. FOS in modulating gut microbiota in the small and large intestine, an ileal-cannulated pig model was adopted to compare the temporal and spatial effects of FOS and citrus pectin (CP) on the gut microbiota. Sixteen terminal ileal-cannulated pigs were randomly divided into 2 groups and fed with a standard diet supplemented with either 3% FOS or 3% CP for 28 d. The CP group and FOS group showed different microbial composition, especially in the feces, with time and location as major factors affecting microbiota in the CP group, and with only location contribution in the FOS group. In the feces, relative to the FOS group, the CP group showed higher abundance of Christensenellaceae R-7 group and Ruminococcaceae UCG-010 and lower abundance of Mitsuokella and Olsenella (adjusted P < 0.05), a higher level of short-chain fatty acids and a lower level of lactate at both d 14 and 25 (P < 0.05), and more copy numbers of genes encoding key enzymes related to propionate (mmdA) and butyrate (BCoAT) production and lactate utilization (LcdA) (P < 0.05), indicating a greater degree of microbial carbohydrate fermentation.

This study was the first to apply multi-omics technologies to investigate the dynamic variations in gut microbiota and their metabolic profiles across different ages of Kunming dogs. Furthermore, we systematically examined the associations between these microbial alterations and police performance metrics, providing a theoretical foundation for enhancing the working capabilities of Kunming dogs through targeted modulation of intestinal microecology.

Analysis of 16S rRNA sequencing demonstrated that gut microbial diversity and stability were highest during the young dog stage, gradually declining with age. Metagenomic analysis revealed that the abundance of Lactobacillus acidophilus, Lactobacillus johnsonii, Limosilactobacillus reuteri, Ligilactobacillus animalis and Muribaculum gordoncarteri were strongly correlated with police performance.

Our study identified elevated fecal trace amine levels in ulcerative colitis (UC) patients and DSS-induced colitis mice. In vitro, exposure to these trace amines enhanced 5-HT secretion in QGP-1 cells and ex vivo mouse colonic tissues, and this effect could be blocked by the TAAR1 antagonist EPPTB.

This systematic review aimed to evaluate the effectiveness of probiotic strains and physicochemical factors in reducing biogenic amine levels during cheese ripening. Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, a comprehensive literature search was conducted in PubMed, Scopus, Web of Science, ScienceDirect, and Google Scholar for studies published between 2010 and 2024. Fourteen studies met the inclusion criteria. Among the identified biogenic amines, tyramine and histamine were most frequently reported at high concentrations.

Liquid fermentation technology has been demonstrated to be an effective method of reducing antinutritional factors and enhancing the nutritional value of complete feeds. However, there is a lack of systematic research on the liquid fermentation and the screening of bacterial strains for use. In the present study, Bacillus subtilis and Lactobacillus plantarum characterized by excellent low-temperature tolerance, great enzyme activity, strong bacteriostatic capacity, and exceptional acid production, were evaluated for their suitability in a two-stage (aerobic followed by anaerobic) liquid fermentation process of complete pig feed. The results demonstrated that soybean antigenic protein and crude fiber underwent significant degradation, while crude protein and acid-soluble protein content exhibited significant increases in the feed following two-stage fermentation. Additionally, the accumulation of biogenic amines was inhibited to ensure the palatability of the feed. Furthermore, two-stage fermentation significantly enhanced the antioxidant and enzymatic activity of the feed. High-throughput 16S rRNA sequencing revealed an increased relative abundance of beneficial bacteria and a decreased abundance of pathogenic bacteria after fermentation. This study corroborated that a two-stage fermentation process could enhance the nutritional value, safety, and probiotic functionality of animal feeds. This finding provides a theoretical foundation for the development of functional fermented feeds and provides the necessary technical support for the practical application of liquid fermentation feeds.

This favorable microbial shift was accompanied by a reconfiguration of the intestinal metabolome, characterized by elevated production of beneficial short-chain fatty acids (SCFAs) and decreased levels of pro-inflammatory metabolites such as tyramine. Furthermore, squid-derived CS effectively enhanced intestinal barrier integrity by upregulating key tight junction proteins (ZO-1, occludin, claudin-1), thereby preventing bacterial lipopolysaccharide (LPS) translocation and associated liver injury, as indicated by reduced serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Collectively, these findings demonstrate that dietary squid-derived CS protects against UC by modulating gut microbiota composition to enrich beneficial taxa, restoring microbial metabolite homeostasis, reinforcing the intestinal epithelial barrier, and suppressing inflammatory responses and oxidative stress. This study provides the first evidence that squid-derived CS acts as a novel and promising marine prebiotic candidate for gut health promotion, highlighting its potential as a sustainable functional ingredient derived from processing waste for gut-health-promoting foods."},{"quadrant":"Run3_Eval1_synthesis","attempt":2,"quote":"The results showed that combined histamine and tyramine administration increased cleaved PARP-1 and IL-1β in the liver, as well as MAO-A, total MAO, CRP, and AST/ALT levels.","status":"PASS","error":"","abstract_text":"ID: 36899958\nTitle: Fermented Soybean Paste Attenuates Biogenic Amine-Induced Liver Damage in Obese Mice.\nAbstract: Biogenic amines are cellular components produced by the decarboxylation of amino acids; however, excessive biogenic amine production causes adverse health problems.

Our study identified elevated fecal trace amine levels in ulcerative colitis (UC) patients and DSS-induced colitis mice.

Liquid fermentation technology has been demonstrated to be an effective method of reducing antinutritional factors and enhancing the nutritional value of complete feeds. However, there is a lack of systematic research on the liquid fermentation and the screening of bacterial strains for use. In the present study, Bacillus subtilis and Lactobacillus plantarum characterized by excellent low-temperature tolerance, great enzyme activity, strong bacteriostatic capacity, and exceptional acid production, were evaluated for their suitability in a two-stage (aerobic followed by anaerobic) liquid fermentation process of complete pig feed. The results demonstrated that soybean antigenic protein and crude fiber underwent significant degradation, while crude protein and acid-soluble protein content exhibited significant increases in the feed following two-stage fermentation. Additionally, the accumulation of biogenic amines was inhibited to ensure the palatability of the feed. Furthermore, two-stage fermentation significantly enhanced the antioxidant and enzymatic activity of the feed. High-throughput 16S rRNA sequencing revealed an increased relative abundance of beneficial bacteria and a decreased abundance of pathogenic bacteria after fermentation.

In vivo studies revealed no treatment-related toxicity, behavioural abnormalities, organ damage, bacterial translocation, or adverse immune responses.

Emerging evidence suggests that gut microbial metabolites, such as trace amines (tryptamine, phenethylamine, and tyramine), function as endogenous TAAR1 agonists and may contribute to IBD pathogenesis. Our study identified elevated fecal trace amine levels in ulcerative colitis (UC) patients and DSS-induced colitis mice. In vitro, exposure to these trace amines enhanced 5-HT secretion in QGP-1 cells and ex vivo mouse colonic tissues, and this effect could be blocked by the TAAR1 antagonist EPPTB. In vivo, EPPTB treatment significantly mitigated DSS-induced colitis, as demonstrated by reduced weight loss, improved disease activity index (DAI), preserved colon length, and attenuated histopathological damage. Moreover, TAAR1 blockade reduced pro-inflammatory cytokines (TNF-α, IL-6, IL-1β) and increased IκB-α expression, restored intestinal barrier integrity (upregulating occludin and ZO-1, while downregulating cclaudin-2), and lowered colonic 5-HT levels by suppressing TPH1 expression. These findings suggest that TAAR1 inhibition alleviates colitis by modulating 5-HT signaling, positioning it as a promising therapeutic target for IBD."}],"assistantLogs":[{"query":"Answer in English only.

Beneficial dietary strategies to modulate tyramine levels include specific prebiotic supplementation, protein restriction or modulation, and the use of probiotic strains known to minimize amine production.\n\n### [INTRODUCTION & JUSTIFICATION]\nTyramine is a bioactive trace amine that, while potentially beneficial in specific neurological contexts, exhibits clear pathogenic properties when produced in excess by gut commensals like *Enterococcus*. The provided evidence confirms that \"E. faecium B6 and its metabolite tyramine significantly disrupted the intestinal barrier and increased intestinal permeability in mice.\" Elevated tyramine is linked to \"lipid accumulation, inflammation, and fibrosis in the liver,\" as validated in MASLD models. Dietary intervention acts as a primary modulator of this pathway. For instance, the consumption of yeast-derived beta-glucans has been shown to induce a \"reduction in tyramine, histamine, and cadaverine on day 60.\" Furthermore, metabolic profiling suggests that protein composition is a critical lever, as \"the contents of histamine, spermidine, spermine and tyramine of muscle were decreased with the VLP diet compared to the NP diet.\" Beyond protein restriction, fermentation control is vital; using specific starter cultures like *Lactiplantibacillus plantarum* results in products where \"histamine and tyramine were undetectable.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Tyramine is not inherently \"bad\"; it acts as a ligand for TAAR1, and in specific postprandial contexts, it can even exert anorexigenic (appetite-suppressing) effects via the hypothalamus.\n*   The \"harmfulness\" of tyramine is context-dependent, relying heavily on the integrity of the intestinal barrier and the presence of specific receptors like ADRA2A in stem cells.\n*   Marination of foods (like fish) significantly increases tyramine concentrations, suggesting that kitchen preparation methods are as important as the raw ingredients themselves.\n*   Enterococcaceae are identified as major drivers of tyramine production post-bariatric surgery, a key risk factor for colorectal cancer.\n*   Sulfonation is a natural detoxification pathway, and gut microbes possess enzymes (ASSTs) that can regulate the concentrations of tyramine sulfate.\n*   Low-protein diets (VLP) can specifically reduce the cecal bioamine load in porcine models, suggesting a broader potential for human metabolic health.\n*   Probiotic supplementation with *Lactobacillus acidophilus* and *Lactiplantibacillus plantarum* is highly efficient, capable of reducing total biogenic amine levels by up to 80%.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The literature suggests that the accumulation of tyramine is linked to deleterious effects in the gut-liver axis, including colorectal cancer risk, inflammatory bowel disease (IBD) pathogenesis, and metabolic dysregulation. Specifically, the proposed genotoxic luminal environment is characterized by convergent actions of secondary bile acids, tyramine, and hydrogen sulfide, compounded by butyrate depletion. To mitigate these risks, nutritional interventions focus on modulating the gut microbial composition to minimize tyramine production or enhance its degradation. \n\nBeneficial dietary habits involve replacing specific carbohydrate sources and limiting pro-inflammatory patterns. Research indicates that dietary modifications, including reducing sugars and increasing PUFAs intake, may complement abdominal fat reduction for OAB prevention. Furthermore, the consumption of probiotic strains, such as *Lacticaseibacillus rhamnosus* H7, has shown significant potential in fermentation processes to lower biogenic amine concentrations. Notably, the inoculation significantly enhanced product safety, achieving up to 44.82% reduction in total nitrosamines. Simultaneously, total biogenic amines were reduced by up to 33.17%, particularly putrescine, cadaverine, tyramine, and histamine. Other strategies involve consuming specific prebiotics, as this favorable microbial shift was accompanied by a reconfiguration of the intestinal metabolome, characterized by elevated production of beneficial short-chain fatty acids (SCFAs) and decreased levels of pro-inflammatory metabolites such as tyramine. Therapeutic diets for gastrointestinal health in dogs also suggest that highly digestible diets can result in lower fecal pH and greater fecal concentrations of total short-chain fatty acids and butyrate, serving as potential models for diet-microbiome modulation. Finally, for patients with cirrhosis, nutritional guidance favors balanced patterns, as current recommendations advocate a protein intake of approximately 1.2-1.3 g/kg/day, adjusted for dialysis-related protein losses and inflammatory status. \n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Tyramine oxidation is a specific metabolic function attributed to *Pseudomonas* species within the microbiome.\n*   Fermented foods, often criticized for high amine content, can be optimized using specific starter cultures like *Bacillus velezensis* A1 to drastically reduce biogenic amine levels.\n*   The TAAR1 receptor pathway serves as a sensing mechanism for trace amines like tyramine, where inhibition (e.g., via EPPTB) can mitigate colitis symptoms.\n*   High dietary intake of simple sugars is linked to a shift in microbiome dynamics, reducing the necessity for microbial cooperation and favoring potentially hostile, amine-producing ecological interactions.\n*   The use of iron oxide chitosan nanoparticles (GTPP-IOCHNP) enhances the bioavailability of green tea polyphenols, which modulate hepatic protein expression and inhibit cytochrome P450 enzymes involved in metabolic drug handling.\n*   Dietary patterns following UK-DRV index guidelines, emphasizing fish and fiber, correlate with reduced NAFLD prevalence.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Dietary strategies to mitigate these risks focus on the selection of specific probiotic starters and functional foods that either inhibit biogenic amine production or facilitate their metabolic reduction, thereby preserving intestinal barrier integrity and reducing systemic pro-inflammatory signaling.\n\n### [INTRODUCTION & JUSTIFICATION]\nExcessive tyramine, a biogenic amine produced through amino acid decarboxylation by specific gut microbiota, is increasingly recognized as a deleterious factor in metabolic and intestinal diseases. Clinical and preclinical data reveal that tyramine-producing bacteria—such as *Enterococcus faecium*—can disrupt intestinal barriers and promote hepatic lipid accumulation. Conversely, mitigating tyramine levels through the introduction of specific probiotic strains (e.g., *Lactobacillus* and *Pediococcus* species) or fermentable fiber interventions offers a therapeutic path to improve outcomes in NAFLD and colitis. By modulating the gut-liver axis through the enrichment of beneficial bacteria, these interventions suppress the decarboxylase activities that generate tyramine, thereby restoring intestinal homeostasis and reducing the inflammatory burden on the liver.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Specific probiotic combinations, such as *Lactobacillus acidophilus* and *Lactiplantibacillus plantarum*, can achieve up to an 80% reduction in total biogenic amine levels during food fermentation.\n*   The gut microbiota can be reconfigured by prebiotic interventions (e.g., squid-derived chondroitin sulfate) to shift the metabolome toward beneficial short-chain fatty acids (SCFAs) and away from harmful metabolites like tyramine.\n*   Fermented soybean paste (Doenjang) has been shown to reduce biogenic amine-induced liver damage and improve survival rates in obese mouse models of NAFLD.\n*   The presence of tyramine in the gut is not exclusively endogenous; certain dietary inputs can directly increase amine levels if the microbiota environment favors amino acid fermentation over carbohydrate fermentation.\n*   Inhibitors of trace amine signaling, such as the TAAR1 antagonist EPPTB, show potential in alleviating colitis symptoms by suppressing the downstream effects of elevated gut trace amines.\n*   Metabolic profiling of gut ecosystems in diseased populations reveals that tyramine production is often linked to the down-regulation of beneficial metabolic pathways, such as riboflavin metabolism in pediatric non-organic anorexia.\n*   Microbiome-host interactions indicate that even in the absence of exogenous dietary tyramine, high-fat diets can promote the proliferation of tyramine-producing bacteria, worsening liver fibrosis and inflammation.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Explain this data in simple terms for a non-expert.","finalResponse":"To put it simply, tyramine is a substance (called a biogenic amine) that your gut bacteria can produce when they break down certain proteins from your food. While your body naturally handles small amounts of it, too much tyramine can cause problems for your health, specifically by damaging the lining of your gut and putting extra stress on your liver [ID: 41299593, 38788722].\n\nThink of your gut like a factory. If the \"wrong\" bacteria (like *Enterococcus*) take over, they act like bad employees who produce too much waste, which in this case is tyramine [ID: 38738766, 39593339]. This waste can lead to inflammation and fat buildup in your liver [ID: 38738766, 41299593].\n\nTo improve your gut and liver health, you want to shift the environment to favor \"good\" bacteria that don't produce these harmful amines. Here is how you can do that according to the research:\n\n1. **Choose the Right Probiotics:** Some friendly bacteria—like certain strains of *Lactobacillus*—actually work to block the production of tyramine [ID: 41494586, 41795531]. Using these as part of a healthy diet or in fermented foods can significantly lower the total amount of harmful amines in your system [ID: 41494586].\n2. **Include Prebiotics:** Prebiotics act as food for the \"good\" bacteria. For example, specific fibers can help change your gut environment to produce healthy compounds instead of harmful ones like tyramine [ID: 42083198].\n3. **Be Careful with Fermented Foods:** While fermented foods can be healthy, they can sometimes be high in tyramine depending on how they are made [ID: 22061231, 39593339]. However, when they are made with \"smart\" starter cultures, the tyramine levels can be kept almost undetectable [ID: 40647126, 41795531].\n4. **Watch Your Protein and Sugar Balance:** Diets lower in certain proteins or balanced with more fiber can help reduce the \"waste\" produced by gut bacteria [ID: 36178065, 42387898]. Eating fewer simple sugars also helps, as sugar can change the gut environment in ways that favor those \"bad\" bacteria [ID: 42387898].\n\nIn essence, by eating foods that support good bacteria and avoiding patterns that trigger the bad ones, you can help keep your gut lining strong and your liver functioning smoothly.","memoryMode":"dolphin","contextLength":62596,"historyLength":2293,"fullPrompt":"> **SEMANTIC DRIFT IS DISABLED (STRICT MODE):** > **RAG AMNESIA IS ACTIVE:** You must rely **exclusively** on the provided context. >  > **THE ZERO-TOLERANCE GATE:** > 1.

Beneficial dietary strategies to modulate tyramine levels include specific prebiotic supplementation, protein restriction or modulation, and the use of probiotic strains known to minimize amine production.\n\n### [INTRODUCTION & JUSTIFICATION]\nTyramine is a bioactive trace amine that, while potentially beneficial in specific neurological contexts, exhibits clear pathogenic properties when produced in excess by gut commensals like *Enterococcus*. The provided evidence confirms that \"E. faecium B6 and its metabolite tyramine significantly disrupted the intestinal barrier and increased intestinal permeability in mice.\" Elevated tyramine is linked to \"lipid accumulation, inflammation, and fibrosis in the liver,\" as validated in MASLD models. Dietary intervention acts as a primary modulator of this pathway. For instance, the consumption of yeast-derived beta-glucans has been shown to induce a \"reduction in tyramine, histamine, and cadaverine on day 60.\" Furthermore, metabolic profiling suggests that protein composition is a critical lever, as \"the contents of histamine, spermidine, spermine and tyramine of muscle were decreased with the VLP diet compared to the NP diet.\" Beyond protein restriction, fermentation control is vital; using specific starter cultures like *Lactiplantibacillus plantarum* results in products where \"histamine and tyramine were undetectable.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Tyramine is not inherently \"bad\"; it acts as a ligand for TAAR1, and in specific postprandial contexts, it can even exert anorexigenic (appetite-suppressing) effects via the hypothalamus.\n*   The \"harmfulness\" of tyramine is context-dependent, relying heavily on the integrity of the intestinal barrier and the presence of specific receptors like ADRA2A in stem cells.\n*   Marination of foods (like fish) significantly increases tyramine concentrations, suggesting that kitchen preparation methods are as important as the raw ingredients themselves.\n*   Enterococcaceae are identified as major drivers of tyramine production post-bariatric surgery, a key risk factor for colorectal cancer.\n*   Sulfonation is a natural detoxification pathway, and gut microbes possess enzymes (ASSTs) that can regulate the concentrations of tyramine sulfate.\n*   Low-protein diets (VLP) can specifically reduce the cecal bioamine load in porcine models, suggesting a broader potential for human metabolic health.\n*   Probiotic supplementation with *Lactobacillus acidophilus* and *Lactiplantibacillus plantarum* is highly efficient, capable of reducing total biogenic amine levels by up to 80%.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The literature suggests that the accumulation of tyramine is linked to deleterious effects in the gut-liver axis, including colorectal cancer risk, inflammatory bowel disease (IBD) pathogenesis, and metabolic dysregulation. Specifically, the proposed genotoxic luminal environment is characterized by convergent actions of secondary bile acids, tyramine, and hydrogen sulfide, compounded by butyrate depletion. To mitigate these risks, nutritional interventions focus on modulating the gut microbial composition to minimize tyramine production or enhance its degradation. \n\nBeneficial dietary habits involve replacing specific carbohydrate sources and limiting pro-inflammatory patterns. Research indicates that dietary modifications, including reducing sugars and increasing PUFAs intake, may complement abdominal fat reduction for OAB prevention. Furthermore, the consumption of probiotic strains, such as *Lacticaseibacillus rhamnosus* H7, has shown significant potential in fermentation processes to lower biogenic amine concentrations. Notably, the inoculation significantly enhanced product safety, achieving up to 44.82% reduction in total nitrosamines. Simultaneously, total biogenic amines were reduced by up to 33.17%, particularly putrescine, cadaverine, tyramine, and histamine. Other strategies involve consuming specific prebiotics, as this favorable microbial shift was accompanied by a reconfiguration of the intestinal metabolome, characterized by elevated production of beneficial short-chain fatty acids (SCFAs) and decreased levels of pro-inflammatory metabolites such as tyramine. Therapeutic diets for gastrointestinal health in dogs also suggest that highly digestible diets can result in lower fecal pH and greater fecal concentrations of total short-chain fatty acids and butyrate, serving as potential models for diet-microbiome modulation. Finally, for patients with cirrhosis, nutritional guidance favors balanced patterns, as current recommendations advocate a protein intake of approximately 1.2-1.3 g/kg/day, adjusted for dialysis-related protein losses and inflammatory status. \n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Tyramine oxidation is a specific metabolic function attributed to *Pseudomonas* species within the microbiome.\n*   Fermented foods, often criticized for high amine content, can be optimized using specific starter cultures like *Bacillus velezensis* A1 to drastically reduce biogenic amine levels.\n*   The TAAR1 receptor pathway serves as a sensing mechanism for trace amines like tyramine, where inhibition (e.g., via EPPTB) can mitigate colitis symptoms.\n*   High dietary intake of simple sugars is linked to a shift in microbiome dynamics, reducing the necessity for microbial cooperation and favoring potentially hostile, amine-producing ecological interactions.\n*   The use of iron oxide chitosan nanoparticles (GTPP-IOCHNP) enhances the bioavailability of green tea polyphenols, which modulate hepatic protein expression and inhibit cytochrome P450 enzymes involved in metabolic drug handling.\n*   Dietary patterns following UK-DRV index guidelines, emphasizing fish and fiber, correlate with reduced NAFLD prevalence.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Dietary strategies to mitigate these risks focus on the selection of specific probiotic starters and functional foods that either inhibit biogenic amine production or facilitate their metabolic reduction, thereby preserving intestinal barrier integrity and reducing systemic pro-inflammatory signaling.\n\n### [INTRODUCTION & JUSTIFICATION]\nExcessive tyramine, a biogenic amine produced through amino acid decarboxylation by specific gut microbiota, is increasingly recognized as a deleterious factor in metabolic and intestinal diseases. Clinical and preclinical data reveal that tyramine-producing bacteria—such as *Enterococcus faecium*—can disrupt intestinal barriers and promote hepatic lipid accumulation. Conversely, mitigating tyramine levels through the introduction of specific probiotic strains (e.g., *Lactobacillus* and *Pediococcus* species) or fermentable fiber interventions offers a therapeutic path to improve outcomes in NAFLD and colitis. By modulating the gut-liver axis through the enrichment of beneficial bacteria, these interventions suppress the decarboxylase activities that generate tyramine, thereby restoring intestinal homeostasis and reducing the inflammatory burden on the liver.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Specific probiotic combinations, such as *Lactobacillus acidophilus* and *Lactiplantibacillus plantarum*, can achieve up to an 80% reduction in total biogenic amine levels during food fermentation.\n*   The gut microbiota can be reconfigured by prebiotic interventions (e.g., squid-derived chondroitin sulfate) to shift the metabolome toward beneficial short-chain fatty acids (SCFAs) and away from harmful metabolites like tyramine.\n*   Fermented soybean paste (Doenjang) has been shown to reduce biogenic amine-induced liver damage and improve survival rates in obese mouse models of NAFLD.\n*   The presence of tyramine in the gut is not exclusively endogenous; certain dietary inputs can directly increase amine levels if the microbiota environment favors amino acid fermentation over carbohydrate fermentation.\n*   Inhibitors of trace amine signaling, such as the TAAR1 antagonist EPPTB, show potential in alleviating colitis symptoms by suppressing the downstream effects of elevated gut trace amines.\n*   Metabolic profiling of gut ecosystems in diseased populations reveals that tyramine production is often linked to the down-regulation of beneficial metabolic pathways, such as riboflavin metabolism in pediatric non-organic anorexia.\n*   Microbiome-host interactions indicate that even in the absence of exogenous dietary tyramine, high-fat diets can promote the proliferation of tyramine-producing bacteria, worsening liver fibrosis and inflammation.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

In this study, we aimed to explore the role of gut microbial tyramine in intestinal damage and MASLD development in children. We investigated the functions and mechanisms of previously isolated Enterococcus faecium B6 (E. faecium B6) and its derived tyramine in a mice model of intestinal injury and MASLD development. An integrative analysis of transcriptomics and proteomics was performed on mouse liver to explore the molecular mechanisms of tyramine in MASLD progression. Targeted metabolomics was performed using fecal samples from a hospital-based population (27 MASLD cases and 27 matched controls) to measure tyramine levels. The association of serum tyramine and MASLD risk was then validated in a school-based population, using serum samples of 294 children in the MASLD group and 235 controls. E. faecium B6 and its metabolite tyramine significantly disrupted the intestinal barrier and increased intestinal permeability in mice. Tyramine supplementation promoted MASLD-related metabolic phenotype in mice. Multi-omics analysis indicated that the PPAR signaling pathway played an important role in the molecular mechanisms. Tyramine contributed to lipid accumulation mainly by increasing lipid synthesis and lipid uptake but reducing the β-oxidation processes in the mouse liver, as shown by real-time quantitative polymerase chain reaction and western blot. Furthermore, we demonstrated from the hospital-based cohort that tyramine concentration was significantly higher in the MASLD group than in the control group. Consistently, the school-based cohort demonstrated a higher risk of MASLD in the high-tyramine group compared to the low-tyramine group, with adjusted odds ratios (ORs) and 95% confidence intervals (CIs) of 3.65 (95% CI: 2.66-4.32). These results demonstrated that gut microbial tyramine effectively induced intestinal damage and facilitated MASLD development in mice. Tyramine was positively associated with the risk of MASLD in children. This study offered mechanistic insights into the pathogenesis of MASLD and opened therapeutic opportunities for such metabolic diseases."},{"quote":"This favorable microbial shift was accompanied by a reconfiguration of the intestinal metabolome, characterized by elevated production of beneficial short-chain fatty acids (SCFAs) and decreased levels of pro-inflammatory metabolites such as tyramine.","source_id":"42083198","status":"PASS","error":"","abstract_text":"ID: 42083198\nTitle: Squid cartilage-derived chondroitin sulfate from Uroteuthis chinensis: a novel marine prebiotic modulating gut microbiota and ameliorating ulcerative colitis.\nAbstract: This study evaluated the prebiotic potential of chondroitin sulfate (CS) derived from the cartilage of the squid Uroteuthis chinensis, and its protective effects against dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) in mice. Dietary intervention with squid-derived CS significantly attenuated characteristic UC symptoms, including body weight loss, colon shortening, and histopathological damage. Mechanistic analyses revealed that squid-derived CS exerted potent anti-inflammatory effects by downregulating key pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) and alleviated oxidative stress by enhancing colonic antioxidant capacity, as evidenced by increased activities of catalase (CAT) and superoxide dismutase (SOD) and reduced myeloperoxidase (MPO) activity. Integrated 16S rRNA gene sequencing and metabolomics analyses demonstrated that squid-derived CS profoundly restructured gut microbial community composition by enriching putative beneficial bacteria (e.g., Bifidobacterium, Clostridium, Blautia) while reducing opportunistic pathogens (e.g., Enterococcus, Sutterellaceae, Clostridia_UCG-014). This favorable microbial shift was accompanied by a reconfiguration of the intestinal metabolome, characterized by elevated production of beneficial short-chain fatty acids (SCFAs) and decreased levels of pro-inflammatory metabolites such as tyramine. Furthermore, squid-derived CS effectively enhanced intestinal barrier integrity by upregulating key tight junction proteins (ZO-1, occludin, claudin-1), thereby preventing bacterial lipopolysaccharide (LPS) translocation and associated liver injury, as indicated by reduced serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Collectively, these findings demonstrate that dietary squid-derived CS protects against UC by modulating gut microbiota composition to enrich beneficial taxa, restoring microbial metabolite homeostasis, reinforcing the intestinal epithelial barrier, and suppressing inflammatory responses and oxidative stress. This study provides the first evidence that squid-derived CS acts as a novel and promising marine prebiotic candidate for gut health promotion, highlighting its potential as a sustainable functional ingredient derived from processing waste for gut-health-promoting foods."},{"quote":"Enterococcus-derived tyramine suppresses ISC proliferation, thereby impairing epithelial regeneration and exacerbating DSS-induced colitis through ADRA2A.","source_id":"38788722","status":"PASS","error":"","abstract_text":"ID: 38788722\nTitle: Enterococcus-derived tyramine hijacks α2A-adrenergic receptor in intestinal stem cells to exacerbate colitis.\nAbstract: Inflammatory bowel disease (IBD) is characterized by dysbiosis of the gut microbiota and dysfunction of intestinal stem cells (ISCs). However, the direct interactions between IBD microbial factors and ISCs are undescribed. Here, we identify α2A-adrenergic receptor (ADRA2A) as a highly expressed GPCR in ISCs. Through PRESTO-Tango screening, we demonstrate that tyramine, primarily produced by Enterococcus via tyrosine decarboxylase (tyrDC), serves as a microbial ligand for ADRA2A. Using an engineered tyrDC-deficient Enterococcus faecalis strain and intestinal epithelial cell-specific Adra2a knockout mice, we show that Enterococcus-derived tyramine suppresses ISC proliferation, thereby impairing epithelial regeneration and exacerbating DSS-induced colitis through ADRA2A. Importantly, blocking the axis with an ADRA2A antagonist, yohimbine, disrupts tyramine-mediated suppression on ISCs and alleviates colitis.

This knowledge gap prompted our study of the microbial ecology and amine formation in marinated and unmarinated modified atmosphere commercially packaged rainbow trout fillet strips. According to our findings, marination increased the maximum concentrations (7-8 log CFU/g) of psychrotrophic bacteria by one logarithmic unit and led to 5 times higher average tyramine concentrations than the corresponding unmarinated product. Instead, trimethylamine concentrations were 30 times higher in the unmarinated product than those in the marinated one. According to the 16 S rRNA sequence analyses, lactic acid bacteria (LAB) predominated in the marinated strips one day after the use-by date, whereas in the unmarinated strips Fusobacteriaceae and LAB were the dominating taxa. Based on the culture-dependent analysis, Latilactobacillus fuchuensis was the prevailing LAB in both products. Since the subset of L. fuchuensis strains tested was able to produce tyramine in vitro, we hypothesise that the use of the acidic marinade activated the production of tyrosine-decarboxylating enzymes in L. fuchuensis and led to the increased tyramine concentrations."},{"quote":"The contents of histamine, spermidine, spermine and tyramine of muscle were decreased with the VLP diet compared to the NP diet (P < 0.05).","source_id":"36178065","status":"PASS","error":"","abstract_text":"ID: 36178065\nTitle: Effects of low protein diet with a balanced amino acid pattern on growth performance, meat quality and cecal microflora of finishing pigs.\nAbstract: The present study aimed to investigate the effects of low protein diets balanced with four amino acids on growth performance, meat quality and cecal microflora of finishing pigs.

Sulfotransferases catalyze these reactions by transferring a sulfo group from a donor to an acceptor molecule. Human cytosolic sulfotransferases use only 3'-phosphoadenosine 5'-phosphosulfate (PAPS) as a donor to sulfonate a variety of chemicals. Less understood are microbial aryl-sulfate sulfotransferases (ASSTs), which catalyze sulfo transfer reactions, without utilizing PAPS as a donor. Currently, the identity of physiological sulfo donor substrates remains unknown and sulfo acceptor substrates are underexplored. With this study, we aim to understand the potential contribution of a gut microbial enzyme to sulfonation chemistry by uncovering its substrate preferences. Here, we show that a sulfotransferase (Bacteroides vulgatus ASST) from the prevalent gut microbe B. vulgatus (now Phocaeicola vulgatus) is a versatile catalyst that utilizes a wide range of phenolic molecules as substrates that are commonly encountered by the host.

Although long considered products of host metabolism, these aromatic monoamines are now also known to originate in part from the microbiota, where they are synthesized by bacterial aromatic L-amino acid decarboxylases (AADCs). This review explores the distribution, biochemical diversity, and host interactions of microbiota-encoded AADCs, highlighting their roles in gut and skin ecosystems. Bacterial AADCs vary in gene organization, substrate range, and expression patterns across taxa like Ruminococcus gnavus, Clostridium sporogenes, Enterococcus spp., and Staphylococcus spp. These enzymes contribute to microbial fitness through acid stress resistance, energy generation via proton motive force, epithelial adherence and internalization, and niche dominance. Critically, their products modulate host physiology via trace amine-associated receptors (TAARs) and other signaling pathways, influencing neurotransmission, immune response, barrier integrity, and metabolism. Microbiota-derived monoamines can enter systemic circulation and cross the blood-brain barrier, implicating them in disorders ranging from irritable bowel syndrome to neurodegeneration. Emerging data also reveal their impact on wound healing and drug efficacy, notably in Parkinson's disease. By positioning microbial AADCs as key players in host-microbe chemical communication, this review underscores their relevance for health and disease and highlights them as potential therapeutic targets."},{"quote":"10 of 42 LAB strains produced 402-1087 ppm tyramine.

Forty-two lactic acid bacteria (LAB) strains were isolated from seven dry sausages during ripening (0 day, 21 day and 49 day). Their ability to produce histamine and tyramine was studied by HPLC detection from broth cultures after 2 days incubation. The tyramine and histamine concentrations in sausages increased during fermentation. 10 of 42 LAB strains produced 402-1087 ppm tyramine. Four of these 10 contaminant LABs were also histamine-positive (725-1083 ppm). Most of the amine positive strains were found in sausages at the end of ripening and with highest amine levels. On the basis of these results the contaminant LABs play an important role in tyramine and histamine formation during the ripening of dry sausages. Therefore it could be possible to decrease the levels of amines formed by limiting the initial level and growth of these contaminant bacteria."},{"quote":"Pseudomonas, tryptophan-aspartic acid (Trp-Asp), D-Glucose 6-phosphate, Succinic Acid, Biliverdin 1, 5-Diaminopentane, and Tyramine, etc., are potential biomarkers for the quality changes of eel slices during refrigeration.","source_id":"40646988","status":"PASS","error":"","abstract_text":"ID: 40646988\nTitle: Integrated Microbiome and Metabolomics Insights into Meat Quality Changes in Rice-Field Eel Slices During Refrigeration Storage: Effects of ε-Polylysine, Vitamin C, Epigallocatechin Gallate, and Phloretin.\nAbstract: Rice-field eel (Monopterus albus) slices, an important aquatic product in Southeast Asia, are prone to spoilage and deterioration during cold chain storage.

Nevertheless, the conventional surgical castration procedure poses several challenges, including heightened stress and pain, detrimental impacts on animal welfare, and diminished economic efficacy in farming operations. Consequently, immunocastration methods, serving as substitutes for surgical castration, are progressively finding application in livestock. The rumen, an essential and distinctive digestive and absorptive organ in ruminants, has been associated with enhanced meat quality and productive performance following castration in previous research studies, albeit fewer investigations have explored the potential impacts of GnRH immunization on the rumen's internal milieu in sheep post-de-escalation. Hence, the present study delved into evaluating the impact of GnRH immunocastration on the rumen microbiome and metabolomics in male Xizang sheep. This was achieved through the establishment of a GnRH immunocastration animal model and the collection of rumen fluid for microbiological and comprehensive metabolomics investigations. The outcomes of this investigation unveiled that the impact of GnRH immunocastration on body weight gain was more pronounced during the achievement of the castration objective. In addition, the Firmicutes-to-Bacteroidota ratio in the immune male (IM) group exceeded that of the control group (EM), suggesting that GnRH immunodeficiency may enhance the digestion and absorption of feed in male Xizang sheep. At the taxonomic level, the elevated presence of Prevotella and Quinella bacteria in the IM group compared to the EM group indicated that castration influenced a segment of the rumen microbiota in male Xizang sheep, thereby bolstering the digestive and metabolic efficacy of the rumen concerning nutrient utilization, particularly in the breakdown and absorption of proteins, carbohydrates, and lipids, ultimately expediting the fattening process and weight gain in male Xizang sheep following castration. Moreover, analysis of ruminal fluid metabolomics revealed that GnRH immunization had notable impacts on certain metabolites in the ruminal fluid of male Xizang sheep, with metabolites like 5-hydroxyindole acetic acid and 3-hydroxyindole acetic acid showing significant downregulation in the IM group compared to the EM group, while niacin and tyramine exhibited significant upregulation. These findings indicate a profound influence of GnRH immunization on the maintenance of ruminal equilibrium and ruminal health (including the health of ruminal epithelial cells). This study validates that GnRH immunocastration not only achieves the objectives of castration but also enhances ruminal health in male Xizang sheep, thus laying a foundational theoretical basis for the application and dissemination of GnRH immunocastration technology."},{"quote":"metabolomic analysis showed that differential metabolites were enriched in the neuroactive ligand-receptor interaction pathway, in which GABA (γ-aminobutyric acid), histamine and tyramine metabolites were positively correlated with the above species and police performance.","source_id":"41840712","status":"PASS","error":"","abstract_text":"ID: 41840712\nTitle: Characterization of age-related changes in the gut microbiome and metabolome of Kunming dogs and their associations with police performance.\nAbstract: Gut microbiota plays a pivotal role in regulating the host's central nervous system (CNS) activity and behavior. However, its influence on the police performance of Kunming dogs and the underlying mechanisms remain largely unexplored. This study was the first to apply multi-omics technologies to investigate the dynamic variations in gut microbiota and their metabolic profiles across different ages of Kunming dogs. Furthermore, we systematically examined the associations between these microbial alterations and police performance metrics, providing a theoretical foundation for enhancing the working capabilities of Kunming dogs through targeted modulation of intestinal microecology. The study showed that puppies, young dogs and adult dogs had significantly better police performance than elderly dogs, with young dogs exhibiting the highest scores. Analysis of 16S rRNA sequencing demonstrated that gut microbial diversity and stability were highest during the young dog stage, gradually declining with age. Metagenomic analysis revealed that the abundance of Lactobacillus acidophilus, Lactobacillus johnsonii, Limosilactobacillus reuteri, Ligilactobacillus animalis and Muribaculum gordoncarteri were strongly correlated with police performance.

Using untargeted metabolomics, here we show that circulating levels of the metabolite para -tyramine-O-sulfate (pTOS) are increased >1,000-fold in pythons after a single meal. In pythons, pTOS production occurs in a microbiome-dependent manner via sequential decarboxylation and sulfation of dietary tyrosine. In both pythons and mice, pTOS administration activates a neural population in the ventromedial hypothalamus (VMH). In mice, these VMH neurons are required for the anorexigenic effects of pTOS. Chronic administration of pTOS to diet-induced obese male mice suppresses food intake and body weight. pTOS is also present in human blood, where its levels are increased after a meal.

Here, we found that dysbiosis-induced tyramine (TA) suppresses high-fat diet (HFD)-mediated insulin resistance in both Drosophila and mice. In Drosophila, HFD increases cytosolic Ca2+ signaling in enterocytes, which, in turn, suppresses intestinal lipid levels. 16 S rRNA sequencing and metabolomics revealed that HFD leads to increased prevalence of tyrosine decarboxylase (Tdc)-expressing bacteria and resulting tyramine production. Tyramine acts on the tyramine receptor, TyrR1, to promote cytosolic Ca2+ signaling and activation of the CRTC-CREB complex to transcriptionally suppress dietary lipid digestion and lipogenesis in enterocytes, while promoting mitochondrial biogenesis. Furthermore, the tyramine-induced cytosolic Ca2+ signaling is sufficient to suppress HFD-induced obesity and insulin resistance in Drosophila. In mice, tyramine intake also improves glucose tolerance and insulin sensitivity under HFD.

NAFLD is usually linked to obesity and excessive weight. A subset of patients with NAFLD expresses normal or low body mass index; thus, the condition is called non-obese NAFLD or lean NAFLD. However, patients and healthcare professionals have little awareness and understanding of NAFLD in non-obese individuals. Furthermore, preclinical results from non-obese animal models with NAFLD are unclear. Gut microbiota and their metabolites in non-obese/lean-NAFLD patients differ from those in obese NAFLD patients. Therefore, we analyzed the biochemical indices, intestinal flora, and intestinal metabolites in a non-obese NAFLD mouse model established using a methionine-choline-deficient (MCD) diet. The significantly lean MCD mice had a remarkable fatty liver with lower serum triglyceride and free fatty acid levels, as well as higher alanine transaminase and aspartate transaminase levels than normal mice. 16S RNA sequencing of fecal DNA showed that the overall richness and diversity of the intestinal flora decreased in MCD mice, whereas the Firmicutes:Bacteroidota ratio was increased. g_Tuzzerella, s_Bifidobacterium pseudolongum, and s_Faecalibaculum rodentium were the predominant species in non-obese NAFLD mice.

Our findings could be useful to identify and develop drugs to treat non-obese NAFLD and lean NAFLD. Patients and healthcare professionals have little awareness and understanding of NAFLD in non-obese individuals. In fact, about 40% of people with NAFLD worldwide are non-obese, and nearly one-fifth are lean.

Beneficial dietary strategies to modulate tyramine levels include specific prebiotic supplementation, protein restriction or modulation, and the use of probiotic strains known to minimize amine production.\n\n### [INTRODUCTION & JUSTIFICATION]\nTyramine is a bioactive trace amine that, while potentially beneficial in specific neurological contexts, exhibits clear pathogenic properties when produced in excess by gut commensals like *Enterococcus*. The provided evidence confirms that \"E. faecium B6 and its metabolite tyramine significantly disrupted the intestinal barrier and increased intestinal permeability in mice.\" Elevated tyramine is linked to \"lipid accumulation, inflammation, and fibrosis in the liver,\" as validated in MASLD models. Dietary intervention acts as a primary modulator of this pathway. For instance, the consumption of yeast-derived beta-glucans has been shown to induce a \"reduction in tyramine, histamine, and cadaverine on day 60.\" Furthermore, metabolic profiling suggests that protein composition is a critical lever, as \"the contents of histamine, spermidine, spermine and tyramine of muscle were decreased with the VLP diet compared to the NP diet.\" Beyond protein restriction, fermentation control is vital; using specific starter cultures like *Lactiplantibacillus plantarum* results in products where \"histamine and tyramine were undetectable.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Tyramine is not inherently \"bad\"; it acts as a ligand for TAAR1, and in specific postprandial contexts, it can even exert anorexigenic (appetite-suppressing) effects via the hypothalamus.\n*   The \"harmfulness\" of tyramine is context-dependent, relying heavily on the integrity of the intestinal barrier and the presence of specific receptors like ADRA2A in stem cells.\n*   Marination of foods (like fish) significantly increases tyramine concentrations, suggesting that kitchen preparation methods are as important as the raw ingredients themselves.\n*   Enterococcaceae are identified as major drivers of tyramine production post-bariatric surgery, a key risk factor for colorectal cancer.\n*   Sulfonation is a natural detoxification pathway, and gut microbes possess enzymes (ASSTs) that can regulate the concentrations of tyramine sulfate.\n*   Low-protein diets (VLP) can specifically reduce the cecal bioamine load in porcine models, suggesting a broader potential for human metabolic health.\n*   Probiotic supplementation with *Lactobacillus acidophilus* and *Lactiplantibacillus plantarum* is highly efficient, capable of reducing total biogenic amine levels by up to 80%.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

During dairy fermentation, these microorganisms generate bioactive compounds, such as bioactive peptides, exopolysaccharides, organic acids and other metabolites, which may contribute to host health. There is emerging evidence that fermented dairy products can influence gastrointestinal function, immune regulation, metabolic health and cardiovascular risk, via mechanisms involving modulation of the gut microbiota, stabilisation of the epithelial barrier and inflammatory signalling pathways. In addition, fermentation may improve lactose digestion, enhance nutrient bioavailability, and generate peptides with anti-hypertensive or antioxidant properties. However, translating these results into consistent health benefits is challenging due to the significant variability in microbial strains, product composition, processing conditions and dosage. Safety considerations such as biogenic amines, sodium content, allergenicity and antimicrobial resistance also require careful monitoring. Future progress in this field will depend on improved product characterisation, strain-level identification and well-designed human intervention studies that integrate multi-omics approaches. In conclusion, fermented dairy products show great potential as a source of bioactive compounds, but more robust clinical evidence and standardised methodologies are required to firmly establish their role in promoting human health.\n\nID: 42162614\nTitle: Effects of a pulse-based, guidelines-aligned diet on biomarkers relevant to aging: Results from the PRODMED1 randomized controlled crossover feeding trial.\nAbstract: Pulse-based diets are naturally low in methionine, an amino acid whose restriction has been linked to improved metabolic health and longevity. This study evaluated how a pulse-protein diet (PPD), relative to a meat-protein diet (MPD), both aligned with the Dietary Guidelines for Americans (DGA), influenced cardiometabolic and iron-related biomarkers relevant to aging in older adults. This Protein-Distinct Macronutrient-Equivalent Diet 1 (PRODMED1) trial was conducted among Midwestern adults aged ≥60 years. Participants consumed MPD and PPD for eight weeks each, separated by ≥ 2-week washout. Primary protein sources (162 g/d lean pork vs. 331.6 g/d pulses) contributed ≥45% of total dietary protein. Diets were matched for total iron, energy, and macronutrients but differed in heme iron and methionine. Primary outcomes were ferritin, fasting blood glucose, and trimethylamine N-oxide (TMAO); secondary outcomes included inflammation, body composition, lipid-related cardiovascular risk biomarkers, and circulating biogenic amines. Analyses were conducted using robust linear mixed-effects models, adjusted for covariates. Forty-seven participants completed the trial (72% women; age 69.2 ± 6.6 years; BMI 28.6 ± 5.4 kg/m2). Regardless of protein source, both diets improved biomarkers of glucose and lipid metabolism except HDL (all, p < 0.05; no between-diet differences), while TMAO remained unchanged. Total and visceral fat mass declined (both, p < 0.0001; no between-diet differences), with a greater reduction in the visceral-to-total fat ratio during PPD vs. MPD (p < 0.05). PPD demonstrated a larger increase in ferritin relative to MPD (PPD: +15.7 ng/mL vs. MPD: +7.0 ng/mL; between-diet p = 0.027), and CRP decreased in both groups (both, p ≤ 0.001, no between-diet differences). MPD and PPD resulted in distinct circulating biogenic amine profiles (p = 0.001). High-quality DGA-aligned diets improved cardiovascular risk factors irrespective of primary protein sources, underscoring the importance of overall dietary-matrix quality. However, the pulse-based diet conferred additional benefits to visceral-to-total fat ratio and iron status, supporting pulses as a feasible, nutrient-dense, and effective dietary strategy with potential relevance for promoting healthspan in aging populations. The trial is registered at www. gov as NCT05577858 on October 11, 2022.\n\nID: 42061249\nTitle: Gut health in broiler chickens fed a mixture of Hermetia illucens and Tenebrio molitor meals: does it have a key role in shaping bird performance?\nAbstract: Insect meals are promising sustainable protein sources for poultry, but comprehensive insights into their effects on gut health and growth performance are lacking. This study is the first to elucidate relationships between gut health parameters and performance in broilers fed Hermetia illucens (HI) and Tenebrio molitor (TM) meals at 5% or 10% inclusion levels, singly or in a 1:1 combination. A 37-day trial used 420 male Ross 308 chicks randomly allocated to seven treatments: control (C), HI5 (5% HI), HI10 (10% HI), TM5 (5% TM), TM10 (10% TM), MIX5 (5% MIX), and MIX10 (10% MIX). By integrating intestinal histomorphometry, mucin histochemistry, multi-organ histopathology, and multi-omics cecal microbiome characterization, we identified key structural, microbial, and metabolic biomarkers associated with performance variations (false discovery rate [FDR]<0.05 and P < 0.05 for microbiome and histomorphology, respectively). High-performing groups (MIX5, TM5) showed microbiomes enriched in short-chain fatty acid-producing bacteria (Veillonellaceae, Butyricicoccus, Limosilactobacillus crispatus), positively correlated with ADG and ADFI (FDR<0.05) and negatively correlated with FCR (FDR<0.05). Favorable metabolomic profiles (increased dopamine, tyramine, malic and orotic acids; reduced 3-deoxyglucosone, hexanoylcarnitine [FDR<0.05]) and preserved balance between neutral (positively correlated with BW and ADFI [P < 0.05]) and acidic mucins (positively correlated with BW, ADFI and ADG, and negatively correlated with FCR [P < 0.05]) were also observed. Low-performing groups (MIX10, HI10) displayed microbiomes dominated by Ruminococcaceae, Alistipes, and l-Eubacterium (negatively correlated with FCR and associated with purine metabolism alterations [FDR<0.05]), alongside worsened morphology (tendency for reduced villus height in MIX10 [P = 0.07], positively and negatively correlated with ADG and FCR, respectively [P < 0.05], and thinner mucosal/muscular layers [P < 0.05]) and decreased neutral mucins (P < 0.05). TM10 maintained unaffected growth performance via beneficial taxa (Limosilactobacillus crispatus, Tyzzerella), and reduced Campylobacter jejuni and antimicrobial resistance genes (FDR<0.05). Jejunal inflammation, negatively correlated with ADG (P < 0.05), was not influenced by dietary treatments (P > 0.05). In conclusion, specific taxa (Butyricicoccus, Veillonellaceae, Limosilactobacillus crispatus), metabolites (dopamine, tyramine, malic and orotic acids), and mucosal features (villus height, mucin composition) were identified as biomarkers of optimal performance in insect-fed broilers.\n\nID: 41299593\nTitle: Gut microbial tyramine facilitates intestinal damage and metabolic dysfunction-associated steatotic liver disease development.\nAbstract: Emerging evidence indicates that gut microbiota and intestinal injury are crucial in pediatric metabolic dysfunction-associated steatotic liver disease (MASLD), yet the role of key gut microbial metabolites such as tyramine in pediatric MASLD remains largely unknown. In this study, we aimed to explore the role of gut microbial tyramine in intestinal damage and MASLD development in children. We investigated the functions and mechanisms of previously isolated Enterococcus faecium B6 (E. faecium B6) and its derived tyramine in a mice model of intestinal injury and MASLD development. An integrative analysis of transcriptomics and proteomics was performed on mouse liver to explore the molecular mechanisms of tyramine in MASLD progression. Targeted metabolomics was performed using fecal samples from a hospital-based population (27 MASLD cases and 27 matched controls) to measure tyramine levels. The association of serum tyramine and MASLD risk was then validated in a school-based population, using serum samples of 294 children in the MASLD group and 235 controls. E. faecium B6 and its metabolite tyramine significantly disrupted the intestinal barrier and increased intestinal permeability in mice. Tyramine supplementation promoted MASLD-related metabolic phenotype in mice. Multi-omics analysis indicated that the PPAR signaling pathway played an important role in the molecular mechanisms. Tyramine contributed to lipid accumulation mainly by increasing lipid synthesis and lipid uptake but reducing the β-oxidation processes in the mouse liver, as shown by real-time quantitative polymerase chain reaction and western blot. Furthermore, we demonstrated from the hospital-based cohort that tyramine concentration was significantly higher in the MASLD group than in the control group. Consistently, the school-based cohort demonstrated a higher risk of MASLD in the high-tyramine group compared to the low-tyramine group, with adjusted odds ratios (ORs) and 95% confidence intervals (CIs) of 3.65 (95% CI: 2.66-4.32). These results demonstrated that gut microbial tyramine effectively induced intestinal damage and facilitated MASLD development in mice. Tyramine was positively associated with the risk of MASLD in children. This study offered mechanistic insights into the pathogenesis of MASLD and opened therapeutic opportunities for such metabolic diseases.\n\nID: 40593033\nTitle: Growth performance, meat quality, cecal microbiota and metabolomics profile of turkeys fed diets containing black soldier fly (Hermetia illucens) meal.\nAbstract: A trial was conceived to evaluate the effects of the dietary inclusion of defatted BSF larvae meal on growth performance, breast meat quality traits, cecal microbiota composition and metabolomics profile of turkeys. A total of 1512 female turkeys (B.U.T. 6) were divided into two groups (9 replicate pens) fed either a basal diet (CON group) or CON diet with 5% BSF meal from 65 days to slaughtering (105 days; INS group). The administration of BSF meal improved final body weight (10.17 vs. 10.06 kg/bird, respectively for INS and CON; P = 0.04) as well as daily weight gain and feed conversion ratio in the rearing cycle (96.22 vs. 95.23 g/bird/day and 2.127 vs. 2.141, respectively; P = 0.03). Breast meat quality traits and cecal microbiota were only slightly affected by the treatment. The cecal concentration of tyramine was significantly lower in INS turkeys, which showed higher levels of glucose and malonate (P = 0.03). The use of BSF meal tended (0.05 < P < 0.10) to increase the cecal content of isoleucine, betaine and butyrate, and to reduce the amount of 3-phenylpropionate. Overall, the dietary inclusion of 5% BSF meal from 65 to 105 days improved the growth performances of female turkeys mainly through the modulation of the gut metabolomics profile.\n\nID: 40451401\nTitle: Gut microbe-derived aromatic trace amines mediate individual variability in response to herbal medicine CDD-2101 for functional constipation.\nAbstract: Functional constipation (FC), a common gastrointestinal disorder, poses significant therapeutic challenges due to the limited efficacy and durability of current therapies. A novel strategy for addressing FC involves the targeting of gut dysbiosis. Our previous study demonstrated that the botanical drug CDD-2101 alleviated bowel movement disorders in FC patients. Nevertheless, whether the alterations in gut microbiota composition affected by CDD-2101 are associated with improved bowel movements and the gut microbiota-mediated mechanisms of action of CDD-2101 are not yet fully comprehended. Here, we showed that CDD-2101 enriched aromatic trace amines and aromatic trace amines-producing gut bacteria in FC patients, which correlated with enhanced bowel function and increased peripheral serotonin levels. In preclinical studies, treatment with tyramine, one of the aromatic trace amines, improved constipation-like symptoms and upregulated serotonin production in mice. Consistent with these findings, the colonization of mice with tyramine-enriched fecal microbiota from CDD-2101-treated patients or administration of an aromatic trace amines-producing engineered Lactobacillus casei alleviated constipation-like symptoms and enhanced serotonin production. Mechanistically, we showed that aromatic trace amines improved gastrointestinal motility by activating the trace amine-associated receptor 1 (TAAR1)-serotonin biosynthesis axis. Our study provides mechanistic and therapeutic insights into aromatic trace amines as microbial-derived TAAR1 ligands that regulate serotonin production to improve defecation in FC. These results not only support the therapeutic potential of targeting gut microbiota for the treatment of FC but also identify the aromatic trace amines-serotonin axis, as promoted by CDD-2101, as a pivotal therapeutic target for the improvement of FC.

Polyphenols derived from plant-based foods reach the large intestine mostly undigested, where they can interact with the gut microbiota. This explorative study investigated the metabolic responses of gut microbiota to the polyphenols rutin and genistein. Ex vivo anaerobic incubations with pooled fecal samples from volunteers with a BMI <25 (n = 7) and a BMI >40 (n = 7) were analyzed by ESI DI-FT-ICR-MS. Differences in metabolic diversity were observed between the two BMI groups, with the obese group showing a less diverse metabolic response. Metabolomic profiling identified 361 metabolites in 35 substance classes, with notable effects of the polyphenols on amino acid, carbohydrate, nucleotide, and lipid metabolism. Both BMI groups showed increased levels of dipeptides and amino acids and decreased levels of biogenic amines. Among the key findings, glutamine levels increased, which has been associated with obesity-related metabolic processes, while tryptophan levels were also elevated, a factor previously associated with obesity-related pathways. Glycine levels increased in both groups. Additionally, histamine, cadaverine, putrescine, and trimethylamine were reduced after exposure to the polyphenols. Changes in metabolites related to carbohydrate metabolism suggest an influence of rutin and genistein on sugar transport and cell wall synthesis. Furthermore, in the obese group, rutin exposure was associated with increased butyrate levels and decreased lactate levels. These findings contribute to a better understanding of how rutin and genistein interact with the gut microbiota metabolome, with potential implications for metabolic health and obesity-related research.\n\nID: 40294666\nTitle: p-Synephrine ameliorates non-alcoholic fatty liver disease by regulating liver-adipose axis via AMPK/NF-kappa B pathway.\nAbstract: Citrus aurantium L. var. amara Engl. is a folk medicine and dietary supplement popularly used in alleviating indigestion due to food retention and obesity. p-Synephrine, a principal proto-alkaloid in Citrus aurantium L. var. amara Engl., is extensively utilized due to its numerous benefits, particularly its potential to ameliorate obesity. Previous studies of our research demonstrated that p-synephrine had the potential to alleviate insulin resistance (IR) and liver lipid accumulation caused by high-fat diet (HFD), as well as enlargement of cells in adipose tissue. However, the effects of p-synephrine in ameliorating non-alcoholic fatty liver disease (NAFLD) were still unclear. To explore the effects of p-synephrine on HFD-induced NAFLD and its mechanisms. NAFLD mice were developed by HFD feeding and treated with p-synephrine once a day for 21 weeks. The protective effects of p-synephrine against NAFLD and its mechanisms were evaluated by OGTT, ITT, biochemical index measurements, H&E, immunofluorescence, Sirius red staining, oil red O staining, immunohistochemistry, RT-qPCR, Western blot, network pharmacology, and molecular docking assays. The results of network pharmacology suggested that AMPK-α1 might be the core target, and AMPK and insulin signaling pathways might be the key regulatory pathways of p-synephrine to alleviate NAFLD. Molecular docking confirmed AMPK-α1 as a probable direct molecular target. p-Synephrine significantly reduced HFD-induced weight gain of the body, liver, and iWAT. It improved glucose tolerance, insulin tolerance and lipid metabolism disorders caused by HFD. Serum levels of NO, TNF-α, and IL-6 in NAFLD mice were suppressed. AST, ALT, and HYP levels in serum and liver were inhibited. Morphological observation showed p-synephrine alleviated hepatic steatosis and fibrosis. p-Synephrine administration also significantly inhibited hepatic de novo lipogenesis (DNL), as evidenced by its regulation of non-esterified fatty acid (NEFA) and TG contents, as well as SREBP-1c, FASN, and ACC1 mRNA expression levels. p-Synephrine also reversed HFD-induced histopathological changes in iWAT, promoted iWAT browning by increasing UCP1 and PGC-1α expression. Simultaneously, p-synephrine intervention markedly increased phosphorylation levels of IRS-1, PI3K, and Akt, and protein expression of GLUT-4 in iWAT and liver. Expression of TNF-α, IL-6, and IL-1β and NF-κB activation in iWAT and liver were attenuated through the treatment of p-synephrine. Further assays showed that p-synephrine intervention potently regulated AMPK pathway in iWAT and liver of mice. This investigation proposed that p-synephrine had the potential to ameliorate HFD-induced NAFLD by regulating liver-adipose axis through AMPK/NF-κB pathway.\n\nID: 40022152\nTitle: Roux-en-Y gastric bypass-associated fecal tyramine promotes colon cancer risk via increased DNA damage, cell proliferation, and inflammation.\nAbstract: Fecal abundances of Enterobacteriaceae and Enterococcaceae are elevated in patients following Roux-en-Y gastric bypass (RYGB) surgery. Concurrently, fecal concentrations of tyramine, derived from gut bacterial metabolism of tyrosine and/or food, increased post-RYGB. Furthermore, emerging evidence suggests that RYGB is associated with increased colorectal cancer (CRC) risk. However, the causal link between RYGB-associated microbial metabolites and CRC risk remains unclear. Hence, this study investigated the tyrosine metabolism of Enterobacteriaceae and Enterococcaceae strains isolated from patients post-RYGB and explored the causal effects of tyramine on the CRC risk and tumorigenesis using both human colonic cancer cell line (HCT 116) and wild-type and ApcMin/+ mice. We isolated 31 bacterial isolates belonging to Enterobacteriaceae and Enterococcaceae families from the feces of patients with RYGB surgery. By culturing the isolates in tyrosine-supplemented medium, we found that Citrobacter produced phenol as a main product of tyrosine, whereas Enterobacter and Klebsiella produced 4-hydroxyphenylacetate, Escherichia produced 4-hydroxyphenyllactate and 4-hydroxyphenylpyruvate, and Enterococcus and two Klebsiella isolates produced tyramine. These observations suggested the gut bacterial contribution to increased fecal concentrations of tyramine post-RYGB. We subsequently evaluated the impact of tyramine on CRC risk and development. Tyramine induced necrosis and promoted cell proliferation and DNA damage of HCT 116 cells. Daily oral administration of tyramine for 49 days to wild-type mice resulted in visible adenomas in 5 out of 12 mice, accompanied by significantly enhanced DNA damage (γH2AX +) and an increased trend of cell proliferation (Ki67 +) in the ileum, along with an upregulated expression of the cell division cycle gene (Cdc34b) in the colon. To evaluate the impact of tyramine on intestinal tumor growth, we treated ApcMin/+ mice with the same doses of tyramine and duration. These mice showed larger colonic tumor size and increased intestinal cell proliferation and inflammation (e.g., increased mRNA expression of IL-17A and higher number of Ly6G + neutrophils) compared to water-treated ApcMin/+ control mice. Our results collectively suggested that RYGB-associated fecal bacteria could contribute to tyramine production and tyramine increased CRC risk by increasing DNA damage, cell proliferation, and pro-inflammatory responses of the gut. Monitoring and modulating tyramine concentrations in high-risk individuals could aid CRC prognosis and management. Video Abstract.\n\nID: 39596410\nTitle: Diversity of Neurotransmitter-Producing Human Skin Commensals.\nAbstract: Recent findings indicate that human microbiota can excrete trace amines, dopamine, and serotonin. These neurotransmitters (NTs) can either affect classical neurotransmitter signaling or directly trigger trace amine-associated receptors (TAARs), with still unclear consequences for host physiology. Compared to gut microbiota, less information is available on the role of skin microbiota in NT production. To explore this, 1909 skin isolates, mainly from the genera Staphylococcus, Bacillus, and Corynebacterium, were tested for NT production. Only 6.7% of the isolates were capable of producing NTs, all of which belonged to the Staphylococcus genus. Based on substrate specificity, we identified two distinct profiles among the NT producers. One group primarily produced tryptamine (TRY) and phenylethylamine (PEA), while the other mainly produced tyramine (TYM) and dopamine (Dopa). These differing production profiles could be attributed to the activity of two distinct aromatic amino acid decarboxylase enzymes, SadA and TDC, responsible for generating the TRY/PEA and TYM/Dopa product spectra, respectively. SadA and TDC orthologues differ in structure and size; SadA has approximately 475 amino acids, whereas the TDC type consists of about 620 amino acids. The genomic localization of the respective genes also varies: tdc genes are typically found in small, conserved gene clusters, while sadA genes are not. The heterologous expression of sadA and tdc in Escherichia coli yielded the same product spectrum as the parent strains. The possible effects of skin microbiota-derived NTs on neuroreceptor signaling in the human host remain to be investigated.\n\nID: 39530356\nTitle: Pathobiont and symbiont contribute to microbiota homeostasis through Malpighian tubules-gut countercurrent flow in Bactrocera dorsalis.\nAbstract: Host-gut microbiota interactions are more complex than good or bad. Both gut symbiotic bacteria and pathobionts can provide essential functions to their host in one scenario and yet be detrimental to host health in another. So, these gut-dwelling bacteria must be tightly controlled to avoid harmful effects on the host. However, how pathobionts and other symbiotic bacteria coordinate to establish a host immune defense system remains unclear. Here, using a Tephritidae fruit fly Bactrocera dorsalis, we report that both pathobionts and other gut symbiotic bacteria release tyramine, which is recognized by the host insects. These tyramines induce the formation of insect-conserved Malpighian tubules-gut countercurrent flow upon bacterial infection, which requires tyramine receptors and aquaporins. At the same time, pathobionts but not gut symbiotic bacteria induce the generation of reactive oxygen species, which are preserved by the countercurrent flow, promoting bacteria elimination through increasing gut peristalsis. More importantly, our results show that the Malpighian tubules-gut countercurrent flow maintains proper microbiota composition. Our work suggests a model where pathobiont-induced reactive oxygen species are preserved by Malpighian tubules-gut countercurrent flow involving both pathobionts and symbiotic bacteria. Furthermore, our work provides a Malpighian tubules-gut interaction that ensures efficient maintenance of the gut microbiota.\n\nID: 39180084\nTitle: Bacillus species are core microbiota of resistant maize cultivars that induce host metabolic defense against corn stalk rot.\nAbstract: Microbes colonizing each compartment of terrestrial plants are indispensable for maintaining crop health. Although corn stalk rot (CSR) is a severe disease affecting maize (Zea mays) worldwide, the mechanisms underlying host-microbe interactions across vertical compartments in maize plants, which exhibit heterogeneous CSR-resistance, remain largely uncharacterized. Here, we investigated the microbial communities associated with CSR-resistant and CSR-susceptible maize cultivars using multi-omics analysis coupled with experimental verification. Maize cultivars resistant to CSR reshaped the microbiota and recruited Bacillus species with three phenotypes against Fusarium graminearum including niche pre-emption, potential secretion of antimicrobial compounds, and no inhibition to alleviate pathogen stress. By inducing the expression of Tyrosine decarboxylase 1 (TYDC1), encoding an enzyme that catalyzes the production of tyramine and dopamine, Bacillus isolates that do not directly suppress pathogen infection induced the synthesis of berberine, an isoquinoline alkaloid that inhibits pathogen growth. These beneficial bacteria were recruited from the rhizosphere and transferred to the stems but not grains of the CSR-resistant plants. The current study offers insight into how maize plants respond to and interact with their microbiome and lays the foundation for preventing and treating soil-borne pathogens.

Coumaroyltyramine, designated by various nomenclatures such as paprazine, N-p-trans-coumaroyltyramine, p-coumaroyltyramine and N-p-coumaroyltyramine, could be a promising bioactive ingredient to address health issues thanks to its powerful anti-inflammatory and antioxidant effects. This review represents the first in-depth analysis of coumaroyltyramine, an intriguing phenylpropanoid substance found in many species of plants. In fact, an in-depth examination of coumaroyltyramine's biological characteristics, chemical attributes, and synthesis process has been undertaken. All previous research relating to the discovery, extraction, biosynthesis, and characterization of the biologically and pharmacologically active properties of coumaroyltyramine has been reviewed and taken into consideration in this analysis. All articles published in a peer-reviewed English-language journal were examined between the initial compilations of the appropriate database until February 12, 2024. A variety of phytochemicals revealed that coumaroyltyramine is a neutral amide of hydroxycinnamic acid that tends to concentrate in plants as a reaction against infection caused by pathogens and is extracted from several medicinal herbs such as Cannabis sativa, Solanum melongena, Allium bakeri, Annona cherimola, Polygonatum zanlanscianense, and Lycopersicon esculentum. Thanks to its effectiveness in suppressing the effect of the enzyme α-glucosidase, coumaroltyramine has demonstrated antihyperglycemic activity and could have an impact on diabetes and metabolic disorders. It has considerable anti-inflammatory and antioxidant effects. These results were obtained through biological and pharmacological studies in silico, in vivo, and in vitro. In addition, coumaroyltyramine has demonstrated hypocholesterolemic and neuroprotective benefits, thereby diminishing heart and vascular disease incidence and helping to prevent neurological disorders. Other interesting properties of coumaroltyramine include anticancer, antibacterial, anti-urease, antifungal, antiviral, and antidysmenorrheal activities. Targeted pathways encompass activity at different molecular levels, notably through induction of endoplasmic reticulum stress-dependent apoptosis, arrest of the cell cycle, and inhibition of the growth of cancer cells, survival, and proliferation. Although the findings from in silico, in vivo, and in vitro experiments illustrate coumaroyltyramine's properties and modes of action, further research is needed to fully exploit its therapeutic potential. To improve our understanding of the compound's pharmacodynamic effects and pharmacokinetic routes, large-scale research should first be undertaken. To determine whether coumaroyltyramine is clinically safe and effective, further studies are required in the clinical and toxicological fields. This upcoming research will be crucial to achieving the overall potency of this substance as a natural drug and in terms of its potential synergies with other drugs.\n\nID: 39095501\nTitle: Association of plant-based diet indexes with the metabolomic profile.\nAbstract: Plant-based diets have gained attention for their potential benefits on both human health and environmental sustainability. The objective of this study was to investigate the association of plant-based dietary patterns with the endogenous metabolites of healthy individuals and identify metabolites that may act as mediators of the associations between dietary intake and modifiable disease risk factors. Adherence to plant-based dietary patterns was assessed for 170 healthy adults using plant-based diet indexes (PDI). Individuals with higher healthful PDI had lower BMI and fasting glucose and higher HDL-C, while those with higher unhealthful PDI had higher BMI, triacylglycerol and fasting glucose and lower HDL-C. Unhealthful PDI was associated with higher levels of several amino acids and biogenic amines previously associated with cardiometabolic diseases and an opposite pattern was observed for healthful PDI. Furthermore, healthful PDI was associated with higher levels of glycerophosphocholines containing very long-chain fatty acids. Glutamate, isoleucine, proline, tyrosine, α-aminoadipate and kynurenine had a statistically significant mediation effect on the associations between PDI scores and LDL-C, HDL-C and fasting glucose. These findings contribute to the growing evidence supporting the role of plant-based diets in promoting metabolic health and shed light on the potential mechanisms explaining their beneficial health effects.\n\nID: 38965418\nTitle: Gut microbiota metabolite tyramine ameliorates high-fat diet-induced insulin resistance via increased Ca2+ signaling.\nAbstract: The gut microbiota and their metabolites are closely linked to obesity-related diseases, such as type 2 diabetes, but their causal relationship and underlying mechanisms remain largely elusive. Here, we found that dysbiosis-induced tyramine (TA) suppresses high-fat diet (HFD)-mediated insulin resistance in both Drosophila and mice. In Drosophila, HFD increases cytosolic Ca2+ signaling in enterocytes, which, in turn, suppresses intestinal lipid levels. 16 S rRNA sequencing and metabolomics revealed that HFD leads to increased prevalence of tyrosine decarboxylase (Tdc)-expressing bacteria and resulting tyramine production. Tyramine acts on the tyramine receptor, TyrR1, to promote cytosolic Ca2+ signaling and activation of the CRTC-CREB complex to transcriptionally suppress dietary lipid digestion and lipogenesis in enterocytes, while promoting mitochondrial biogenesis. Furthermore, the tyramine-induced cytosolic Ca2+ signaling is sufficient to suppress HFD-induced obesity and insulin resistance in Drosophila. In mice, tyramine intake also improves glucose tolerance and insulin sensitivity under HFD. These results indicate that dysbiosis-induced tyramine suppresses insulin resistance in both flies and mice under HFD, suggesting a potential therapeutic strategy for related metabolic disorders, such as diabetes.\n\nID: 38788722\nTitle: Enterococcus-derived tyramine hijacks α2A-adrenergic receptor in intestinal stem cells to exacerbate colitis.\nAbstract: Inflammatory bowel disease (IBD) is characterized by dysbiosis of the gut microbiota and dysfunction of intestinal stem cells (ISCs). However, the direct interactions between IBD microbial factors and ISCs are undescribed. Here, we identify α2A-adrenergic receptor (ADRA2A) as a highly expressed GPCR in ISCs. Through PRESTO-Tango screening, we demonstrate that tyramine, primarily produced by Enterococcus via tyrosine decarboxylase (tyrDC), serves as a microbial ligand for ADRA2A. Using an engineered tyrDC-deficient Enterococcus faecalis strain and intestinal epithelial cell-specific Adra2a knockout mice, we show that Enterococcus-derived tyramine suppresses ISC proliferation, thereby impairing epithelial regeneration and exacerbating DSS-induced colitis through ADRA2A. Importantly, blocking the axis with an ADRA2A antagonist, yohimbine, disrupts tyramine-mediated suppression on ISCs and alleviates colitis. Our findings highlight a microbial ligand-GPCR pair in ISCs, revealing a causal link between microbial regulation of ISCs and colitis exacerbation and yielding a targeted therapeutic approach to restore ISC function in colitis.\n\nID: 38738766\nTitle: Cultivated Enterococcus faecium B6 from children with obesity promotes nonalcoholic fatty liver disease by the bioactive metabolite tyramine.\nAbstract: Gut microbiota plays an essential role in nonalcoholic fatty liver disease (NAFLD). However, the contribution of individual bacterial strains and their metabolites to childhood NAFLD pathogenesis remains poorly understood. Herein, the critical bacteria in children with obesity accompanied by NAFLD were identified by microbiome analysis. Bacteria abundant in the NAFLD group were systematically assessed for their lipogenic effects. The underlying mechanisms and microbial-derived metabolites in NAFLD pathogenesis were investigated using multi-omics and LC-MS/MS analysis. The roles of the crucial metabolite in NAFLD were validated in vitro and in vivo as well as in an additional cohort. The results showed that Enterococcus spp. was enriched in children with obesity and NAFLD. The patient-derived Enterococcus faecium B6 (E. faecium B6) significantly contributed to NAFLD symptoms in mice. E. faecium B6 produced a crucial bioactive metabolite, tyramine, which probably activated PPAR-γ, leading to lipid accumulation, inflammation, and fibrosis in the liver. Moreover, these findings were successfully validated in an additional cohort. This pioneering study elucidated the important functions of cultivated E. faecium B6 and its bioactive metabolite (tyramine) in exacerbating NAFLD. These findings advance the comprehensive understanding of NAFLD pathogenesis and provide new insights for the development of microbe/metabolite-based therapeutic strategies.\n\nID: 38643372\nTitle: The gut microbiome promotes locomotion of Drosophila larvae via octopamine signaling.\nAbstract: The gut microbiome is a key partner of animals, influencing various aspects of their physiology and behaviors. Among the diverse behaviors regulated by the gut microbiome, locomotion is vital for survival and reproduction, although the underlying mechanisms remain unclear. Here, we reveal that the gut microbiome modulates the locomotor behavior of Drosophila larvae via a specific neuronal type in the brain. The crawling speed of germ-free (GF) larvae was significantly reduced compared to the conventionally reared larvae, while feeding and excretion behaviors were unaffected. Recolonization with Acetobacter and Lactobacillus can fully and partially rescue the locomotor defects in GF larvae, respectively, probably due to the highest abundance of Acetobacter as a symbiotic bacterium in the larval gut, followed by Lactobacillus. Moreover, the gut microbiome promoted larval locomotion, not by nutrition, but rather by enhancing the brain levels of tyrosine decarboxylase 2 (Tdc2), which is an enzyme that synthesizes octopamine (OA). Overexpression of Tdc2 rescued locomotion ability in GF larvae. These findings together demonstrate that the gut microbiome specifically modulates larval locomotor behavior through the OA signaling pathway, revealing a new mechanism underlying larval locomotion regulated by the gut microbiome.\n\nID: 38421203\nTitle: New aspects characterizing non-obese NAFLD by the analysis of the intestinal flora and metabolites using a mouse model.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) is a major public health problem due to the high incidence affecting approximately one-third of the world's population. NAFLD is usually linked to obesity and excessive weight. A subset of patients with NAFLD expresses normal or low body mass index; thus, the condition is called non-obese NAFLD or lean NAFLD. However, patients and healthcare professionals have little awareness and understanding of NAFLD in non-obese individuals. Furthermore, preclinical results from non-obese animal models with NAFLD are unclear. Gut microbiota and their metabolites in non-obese/lean-NAFLD patients differ from those in obese NAFLD patients. Therefore, we analyzed the biochemical indices, intestinal flora, and intestinal metabolites in a non-obese NAFLD mouse model established using a methionine-choline-deficient (MCD) diet. The significantly lean MCD mice had a remarkable fatty liver with lower serum triglyceride and free fatty acid levels, as well as higher alanine transaminase and aspartate transaminase levels than normal mice. 16S RNA sequencing of fecal DNA showed that the overall richness and diversity of the intestinal flora decreased in MCD mice, whereas the Firmicutes:Bacteroidota ratio was increased. g_Tuzzerella, s_Bifidobacterium pseudolongum, and s_Faecalibaculum rodentium were the predominant species in non-obese NAFLD mice. Fecal metabolomics using liquid chromatography-tandem mass spectrometry revealed the potential biomarkers for the prognosis and diagnosis of non-obese NAFLD, including high levels of tyramine glucuronide, 9,12,13-TriHOME, and pantetheine 4'-phosphate, and low levels of 3-carbamoyl-2-phenylpropionaldehyde, N-succinyl-L,L-2,6-diaminopimelate, 4-methyl-5-thiazoleethanol, homogentisic acid, and estriol. Our findings could be useful to identify and develop drugs to treat non-obese NAFLD and lean NAFLD. Patients and healthcare professionals have little awareness and understanding of NAFLD in non-obese individuals. In fact, about 40% of people with NAFLD worldwide are non-obese, and nearly one-fifth are lean. Lean NAFLD unfortunately may be unnoticed for years and remains undetected until hepatic damage is advanced and the prognosis is compromised. This study focused on the lean NAFLD, screened therapeutic agents, and biomarkers for the prognosis and diagnosis using MCD-induced male C57BL/6J mice. The metabolites tyramine glucuronide, 9,12,13-TriHOME, and pantetheine 4'-phosphate, together with the predominant flora including g_Tuzzerella, s_Bifidobacterium pseudolongum, and s_Faecalibaculum rodentium, were specific in non-obese NAFLD mice and might be used as targets for non-obese NAFLD drug exploration. This study is particularly significant for non-obese NAFLDs that need to be more actively noticed and vigilant.\n\nID: 36309426\nTitle: Marination increased tyramine levels in rainbow trout fillet strips packaged under modified atmosphere.\nAbstract: Marinades are increasingly used to manufacture raw fish products. In corresponding meats, marinating is known to have a major effect on the composition of the microbiome, but the effect of marinating on fish is not known as well. This knowledge gap prompted our study of the microbial ecology and amine formation in marinated and unmarinated modified atmosphere commercially packaged rainbow trout fillet strips. According to our findings, marination increased the maximum concentrations (7-8 log CFU/g) of psychrotrophic bacteria by one logarithmic unit and led to 5 times higher average tyramine concentrations than the corresponding unmarinated product. Instead, trimethylamine concentrations were 30 times higher in the unmarinated product than those in the marinated one. According to the 16 S rRNA sequence analyses, lactic acid bacteria (LAB) predominated in the marinated strips one day after the use-by date, whereas in the unmarinated strips Fusobacteriaceae and LAB were the dominating taxa. Based on the culture-dependent analysis, Latilactobacillus fuchuensis was the prevailing LAB in both products. Since the subset of L. fuchuensis strains tested was able to produce tyramine in vitro, we hypothesise that the use of the acidic marinade activated the production of tyrosine-decarboxylating enzymes in L. fuchuensis and led to the increased tyramine concentrations.\n\nID: 36178065\nTitle: Effects of low protein diet with a balanced amino acid pattern on growth performance, meat quality and cecal microflora of finishing pigs.\nAbstract: The present study aimed to investigate the effects of low protein diets balanced with four amino acids on growth performance, meat quality and cecal microflora of finishing pigs. Fifty-four healthy hybrid barrows (Duroc × Landrace × Yorkshire) with an average body weight of 70.12 ± 4.03 kg were randomly assigned to one of the three dietary treatments with six replicate pens per treatment (three barrows per pen). The three dietary treatments included a normal protein diet (NP), a low protein diet (LP) and a very low protein diet (VLP). The average daily gain, average daily feed intake and feed conversion ratio of pigs were not significantly changed with the LP and VLP diets compared to the NP diet (P > 0.05). The water holding capacity and shear force of longissimus dorsi muscle were decreased, whereas the intramuscular fat content of the longissimus dorsi muscle was increased (P < 0.05) in pigs fed with the LP and VLP diets compared to the NP diet. The contents of saturated fatty acids in muscle were decreased (P < 0.05), whereas the content of polyunsaturated fatty acids in muscle was increased (P < 0.01) with the VLP diet compared to the NP diet. The contents of histamine, spermidine, spermine and tyramine of muscle were decreased with the VLP diet compared to the NP diet (P < 0.05). The relative abundance of Turicibacter, Terrisporobacter, Clostridium_sensu_stricto_1 and UCG-005 was higher (P < 0.05), whereas the relative abundance of Lactobacillus and Streptococcus was lower (P < 0.05) in pigs fed with the LP and VLP diets compared to the NP diet. Based on the correlation of cecal microbiota and cecal biogenic amine, the contents of tyramine, spermidine and histamine were negatively correlated with the abundance of Terrisporobacter (P < 0.01) and the content of histamine was positively correlated with the abundance of Lactobacillus (P < 0.01). Balanced with four essential amino acids, the VLP diet with crude protein levels decreased by > 4% increased the intramuscular fat content, changed the fatty acid and amino acid composition of longissimus dorsi muscle and the profile of cecum microbiota, and reduced the content of cecum bioamine, with no negative effect on the growth performance of pigs. © 2022 Society of Chemical Industry.\n\nID: 34799768\nTitle: Duodenal Microbiome and Serum Metabolites Predict Hepatocellular Carcinoma in a Multicenter Cohort of Patients with Cirrhosis.\nAbstract: Hepatocellular carcinoma (HCC) is rapidly increasing in the U.S. and is a leading cause of mortality for patients with cirrhosis. Discovering novel biomarkers for risk stratification of HCC is paramount. We examined biomarkers of the gut-liver axis in a prospective multicenter cohort. Patients with cirrhosis without a history of HCC were recruited between May 2015 and March 2020 and prospectively followed at 3 tertiary care hospitals in Los Angeles. Microbiome analysis was performed on duodenal biopsies and metabolomic analysis was performed on serum samples, collected at the time of enrollment. Optimal microbiome-based survival analysis and Cox proportional hazards regression analysis were used to determine microbiota and metabolite associations with HCC development, respectively. A total of 227 participants with liver cirrhosis contributed a total of 459.58 person-years of follow-up, with 14 incident HCC diagnoses. Male sex (HR = 7.06, 95% CI = 1.02-54.86) and baseline hepatic encephalopathy (HE, HR = 4.65, 95% CI = 1.60-13.52) were associated with developing HCC over follow-up. Adjusting for age, sex, baseline HE, and alkaline phosphatase, an increased risk of HCC were observed for participants with the highest versus lowest three quartiles for duodenal Alloprevotella (HR = 3.22, 95% CI = 1.06-9.73) and serum taurocholic acid (HR = 6.87, 95% CI = 2.32-20.27), methionine (HR = 9.97, 95% CI = 3.02-32.94), and methioninesulfoxide (HR = 5.60, 95% CI = 1.84-17.10). Being in the highest quartile for Alloprevotella or methionine had a sensitivity and specificity for developing HCC of 85.71% and 60.56%, respectively, with an odds ratio of 10.92 (95% CI = 2.23-53.48). Alloprevotella and methionine, methioninesulfoxide, and taurocholic acid predicted future HCC development in a high-risk population of participants with liver cirrhosis.\n\nID: 33976215\nTitle: Gut microbiome modulates Drosophila aggression through octopamine signaling.\nAbstract: Gut microbiome profoundly affects many aspects of host physiology and behaviors. Here we report that gut microbiome modulates aggressive behaviors in Drosophila. We found that germ-free males showed substantial decrease in inter-male aggression, which could be rescued by microbial re-colonization. These germ-free males are not as competitive as wild-type males for mating with females, although they displayed regular levels of locomotor and courtship behaviors. We further found that Drosophila microbiome interacted with diet during a critical developmental period for the proper expression of octopamine and manifestation of aggression in adult males. These findings provide insights into how gut microbiome modulates specific host behaviors through interaction with diet during development.\n\nID: 33846627\nTitle: Gut-inhabiting Clostridia build human GPCR ligands by conjugating neurotransmitters with diet- and human-derived fatty acids.\nAbstract: Human physiology is regulated by endogenous signalling compounds, including fatty acid amides (FAAs), chemical mimics of which are made by bacteria. The molecules produced by human-associated microbes are difficult to identify because they may only be made in a local niche or they require a substrate sourced from the host, diet or other microbes. We identified a set of uncharacterized gene clusters in metagenomics data from the human gut microbiome. These clusters were discovered to make FAAs by fusing exogenous fatty acids with amines. Using an in vitro assay, we tested their ability to incorporate 25 fatty acids and 53 amines known to be present in the human gut, from which the production of six FAAs was deduced (oleoyl dopamine, oleoyl tyramine, lauroyl tryptamine, oleoyl aminovaleric acid, α-linolenoyl phenylethylamine and caproyl tryptamine). These molecules were screened against panels of human G-protein-coupled receptors to deduce their putative human targets. Lauroyl tryptamine is found to be an antagonist to the immunomodulatory receptor EBI2 against its native oxysterol ligand (0.98 μM half-maximal inhibitory concentration), is produced in culture by Eubacterium rectale and is present in human faecal samples. FAAs produced by Clostridia may serve as a mechanism to modulate their host by mimicking human signalling molecules.\n\nID: 42083198\nTitle: Squid cartilage-derived chondroitin sulfate from Uroteuthis chinensis: a novel marine prebiotic modulating gut microbiota and ameliorating ulcerative colitis.\nAbstract: This study evaluated the prebiotic potential of chondroitin sulfate (CS) derived from the cartilage of the squid Uroteuthis chinensis, and its protective effects against dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) in mice. Dietary intervention with squid-derived CS significantly attenuated characteristic UC symptoms, including body weight loss, colon shortening, and histopathological damage. Mechanistic analyses revealed that squid-derived CS exerted potent anti-inflammatory effects by downregulating key pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) and alleviated oxidative stress by enhancing colonic antioxidant capacity, as evidenced by increased activities of catalase (CAT) and superoxide dismutase (SOD) and reduced myeloperoxidase (MPO) activity. Integrated 16S rRNA gene sequencing and metabolomics analyses demonstrated that squid-derived CS profoundly restructured gut microbial community composition by enriching putative beneficial bacteria (e.g., Bifidobacterium, Clostridium, Blautia) while reducing opportunistic pathogens (e.g., Enterococcus, Sutterellaceae, Clostridia_UCG-014). This favorable microbial shift was accompanied by a reconfiguration of the intestinal metabolome, characterized by elevated production of beneficial short-chain fatty acids (SCFAs) and decreased levels of pro-inflammatory metabolites such as tyramine. Furthermore, squid-derived CS effectively enhanced intestinal barrier integrity by upregulating key tight junction proteins (ZO-1, occludin, claudin-1), thereby preventing bacterial lipopolysaccharide (LPS) translocation and associated liver injury, as indicated by reduced serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Collectively, these findings demonstrate that dietary squid-derived CS protects against UC by modulating gut microbiota composition to enrich beneficial taxa, restoring microbial metabolite homeostasis, reinforcing the intestinal epithelial barrier, and suppressing inflammatory responses and oxidative stress. This study provides the first evidence that squid-derived CS acts as a novel and promising marine prebiotic candidate for gut health promotion, highlighting its potential as a sustainable functional ingredient derived from processing waste for gut-health-promoting foods.\n\nID: 41550498\nTitle: The TAAR1 antagonist EPPTB ameliorates colitis via serotonin inhibition.\nAbstract: Inflammatory bowel disease (IBD) is characterized by gut dysbiosis and impaired microbial metabolite signaling. Emerging evidence suggests that gut microbial metabolites, such as trace amines (tryptamine, phenethylamine, and tyramine), function as endogenous TAAR1 agonists and may contribute to IBD pathogenesis. Our study identified elevated fecal trace amine levels in ulcerative colitis (UC) patients and DSS-induced colitis mice. In vitro, exposure to these trace amines enhanced 5-HT secretion in QGP-1 cells and ex vivo mouse colonic tissues, and this effect could be blocked by the TAAR1 antagonist EPPTB. In vivo, EPPTB treatment significantly mitigated DSS-induced colitis, as demonstrated by reduced weight loss, improved disease activity index (DAI), preserved colon length, and attenuated histopathological damage. Moreover, TAAR1 blockade reduced pro-inflammatory cytokines (TNF-α, IL-6, IL-1β) and increased IκB-α expression, restored intestinal barrier integrity (upregulating occludin and ZO-1, while downregulating cclaudin-2), and lowered colonic 5-HT levels by suppressing TPH1 expression. These findings suggest that TAAR1 inhibition alleviates colitis by modulating 5-HT signaling, positioning it as a promising therapeutic target for IBD.\n\nID: 37553712\nTitle: Epstein Barr virus infection in tree shrews alters the composition of gut microbiota and metabolome profile.\nAbstract: Epstein-Barr virus (EBV) infection is a major global threat; its manifestations range from the absence of symptoms to multiorgan malignancies and various gastrointestinal diseases. Analyzing the composition and metabolomic profile of gut microbiota during acute EBV infection might be instrumental in understanding and controlling EBV. Six tree shrews were inoculated with EBV by intravenous injection. Blood was collected at regular intervals thereafter from the femoral vein to detect EBV and inflammatory biomarker. At the same time, tree shrew faeces were collected for 16 S rRNA gene sequencing and Non-targeted metabolomics analysis. 16 S rRNA gene characterization along with β diversity analysis exhibited remarkable alterations in gut microflora structure with a peak at 7 days post-infection(dpi). Some alterations in the relative richness of bacterial taxon were linked to infectious indicators. Of note, Butyricicoccus relative richness was positively linked to EBV presence in the blood and plasma, the opposite correlation was seen with Variovorax and Paramuribaculum. Non-targeted metabolomics indicated the fecal metabolome profile altered during EBV infection, particularly 7 dpi. The relative abundance of geranic acid and undecylenic acid in stool samples was positively linked to systemic inflammatory biomarkers, and an inverse relationship was reported with the estrone glucuronide, linoleic acid, protoporphyrin IX and tyramine. Collectively, EBV infection in this model correlated with changes in the composition and metabolome profile of the gut microbiota.\n\nID: 35983599\nTitle: The comparison of the main dietary and non-dietary trigger factors in women with chronic and episodic migraine.\nAbstract: Migraine is one of the most common neurological diseases and the second cause of disability worldwide. Various trigger factors have been reported in different populations. The current study was designed to extract the main trigger factors using factor analysis, and compare the chronic and episodic patient scores for every extracted pattern. In this cross-sectional study, 300 migrainous women (25-55 years old) participated. A constructed 46-item Likert questionnaire was developed to assess the primary triggers. The validity of the designed questionnaire was assessed by Content Validity Ratio and Content Validity Index coefficients. The test-retest method was employed to assess reliability. The exploratory factor analysis was performed to extract patterns of correlation among 46 triggers. Each participant was given a score for every extracted pattern. The mean scores of chronic and episodic patients were compared using the Mann-Whitney test. The mean body mass index of participants was 28.17 ± 5.44 kg/m2 . Most participants (90.7%) had migraine without aura. Four factors were extracted using factor analysis that explained 22.37% of the total variance: (1) environmental and behavioural factors; (2) condiments; (3) nitrite, tyramine and caffeine; and (4) fats. None of these factors explained the difference between chronic and episodic migrainous women. The current study suggests that environmental and behavioural factors, relative to dietary triggers, play an essential role in causing migraine in women and more than dietary triggers. The most important triggers did not differ between episodic and chronic migrainous women.\n\nID: 30841454\nTitle: Effect of N-methyltyramine on the regulation of adrenergic receptors via enzymatic epinephrine synthesis for the treatment of gastrointestinal disorders.\nAbstract: Citri Reticulatae Pericarpium (CRP), Aurantii Fructus Immaturus (AFI) and Aurantii Fructus (AF) are all important Citrus species used in traditional Chinese medicines (TCMs) for the treatment of gastrointestinal disorders. Although they have been used since ancient times and are still in use today, the mechanistic basis for their regulation of adrenergic receptors (ARs) is still not clear. In this study, we aimed to determine the active components and mechanisms of action of CRP, AFI and AF in treating gastrointestinal disorders related to ARs. First, the phenethylamine alkaloid components of CRP, AFI and AF were identified and compared across 30 samples of three Citrus species by UPLC-Q/TOF-MS in combination with content difference analysis. Second, the effect of the main active alkaloid component on AR-based gastrointestinal disorders was investigated by an in vivo small intestinal propulsive test and an in vitro relaxing small intestinal smooth muscle activity test. The mechanism of AR regulation of the active alkaloid was further studied by evaluating its effect on relaxing small intestinal smooth muscle in the presence of an inhibitor. Lastly, the enzymes, which played an important role in epinephrine synthesis and AR regulation, were detected by immunohistochemistry. Three phenethylamine AR regulators (N-methyltyramine, synephrine and hordenine) in CRP, AFI and AF were characterized. It was found that N-methyltyramine could relax mouse small intestinal smooth muscle and inhibit small intestinal propulsion. The effect of N-methyltyramine on relaxing small intestinal smooth muscle could be inhibited by a-methyl-l-tyrosine. The enzymes related epinephrine synthesis and AR function were found in the mouse small intestine. The biotransformation process that converts N-methyltyramine to epinephrine was determined. The treatment of gastrointestinal disorders of CRP, AFI and AF is associated with their alkaloid component N-methyltyramine via the regulation of ARs, and the mechanism is considered to be the biotransformation of N-methyltyramine to epinephrine by serial synthase, which takes place at the nerves cells in small intestine.\n\nID: 30013475\nTitle: Trace Amine-Associated Receptors as Novel Therapeutic Targets for Immunomodulatory Disorders.\nAbstract: Trace amines and their receptors (trace amine-associated receptors; TAARs) are an emerging pharmacological target for the treatment of human disorders. While most studies have focused on their therapeutic potential for neurologic and psychiatric disorders, TAARs are also expressed throughout the periphery, including prominent expression in human leukocytes. Furthermore, recent independent, unbiased metabolomic studies have consistently identified one or more TAAR ligands as potential etiologic factors in inflammatory bowel disease (IBD). The putative role of TAARs in diseases such as IBD that are associated with hyperactive immune responses has not, however, previously been systematically addressed. Here, we review the current state of the knowledge of the effects of TAARs on leukocyte function, in particular in the context of mucosal epithelial cells that interface with the environment; developing a model whereby TAARs may be considered as a novel therapeutic target for disorders associated with dysregulated immune responses to environmental factors. In this model, we hypothesize that altered trace amine homeostasis results in hyperactivity of the immune system. Such loss of homeostasis can occur through many different mechanisms including TAAR polymorphisms and altered trace amine load due to changes in host synthesis and/or degradative enzymes, diet, or microbial dysbiosis. The resulting alterations in TAAR functioning can then lead to a loss of homeostasis of leukocyte chemotaxis, differentiation, and activation, as well as an altered ability of members of the microbiota to adhere to and penetrate the epithelial cell layers. Such changes would generate a pro-inflammatory state at mucosal epithelial barrier layers that can manifest as clinical symptomatology such as that seen in IBD. These alterations may also have the potential to induce systemic effects, which could possibly contribute to immunomodulatory disorders in other systems, including neurological diseases.\n\nID: 26239676\nTitle: N‑trans‑ρ‑caffeoyl tyramine isolated from Tribulus terrestris exerts anti‑inflammatory effects in lipopolysaccharide‑stimulated RAW 264.7 cells.\nAbstract: Inflammation is induced by the expression of cyclooxygenase‑2 (COX‑2), which is an important mediator of chronic inflammatory diseases, such as rheumatoid arthritis, asthma and inflammatory bowel disease. Tribulus terrestris (T. terrestris) is known to have a beneficial effect on inflammatory diseases. In this study, we investigated the effects of N‑trans‑ρ‑caffeoyl tyramine (CT) isolated from T. terrestris on the production of nitric oxide (NO), and the expression of pro‑inflammatory cytokines and COX‑2 in lipopolysaccharide (LPS)‑stimulated RAW 264.7 cells. We also aimed to elucidate the molecular mechanisms involved. We found that the ethanolic extract of T. terrestris (EETT) and CT inhibited the production of NO, tumor necrosis factor‑α (TNF‑α), interleukin (IL)‑6 and IL‑10 in the LPS‑stimulated RAW 264.7 cells in a dose‑dependent manner. They were determined by reverse transcription-polymerase chain reaction (RT-PCR) and enzyme-linked immunosorbent assay (ELISA). In addition, CT markedly suppressed the expression of COX‑2 and the production of prostaglandin E2 (PGE2) in response to LPS stimulation. Furthermore, CT markedly decreased p‑c‑Jun N‑terminal kinase (p‑JNK) protein expression in LPS‑stimulated RAW 264.7 cells. COX-2 and p-JNK were measured by western blot analysis. Taken together, these findings indicate that CT isolated from T. terrestris is a novel and potent modulator of inflammatory responses. Thus, it may prove benefiical to further evaluate CT as a possible treatment for chronic inflammatory diseases.\n\nID: 9660426\nTitle: Relation of endometriosis and neuromuscular disease of the gastrointestinal tract: new insights.\nAbstract: To investigate the neuromuscular activity of the gastrointestinal tract by antroduodenal manometry in women with endometriosis documented by laparoscopy, to assess the effects of diet and drug therapy on symptoms, and to assess the bacterial overgrowth that is commonly associated with these nerve diseases. Prospective, open-label study. A clinical center for the care of women's health. Fifty women with endometriosis documented by laparoscopy and gastrointestinal tract symptoms characterized by chronic abdominal pain, nausea, vomiting, early satiety, bloating and distention, and altered bowel habits. Motility of the gastrointestinal tract was recorded and bacterial overgrowth was assessed. Treatment consisted of dietary changes, including reduction of glycemic carbohydrates, balancing with omega 9 oils, elimination of foods with caffeine and tyramine, and addition of omega 3 fatty acids, as well as drug therapy with clonazepam (0.25 mg 3 times per day). All 50 women showed a characteristic motility change (ampulla of Vater-duodenal wall spasm, a seizure equivalent of the enteric nervous system). Forty of the women showed bacterial overgrowth. There was a significant reduction in the total symptom score after 8 weeks of treatment. This study suggests that endometriosis and gastrointestinal tract symptoms are a result of the dysfunction of hollow organs. Correction of the biochemical imbalance of the eicosanoid system and the hypersecretion of insulin that results from excessive intake of glycemic carbohydrates and lack of essential fatty acids significantly decreases symptoms in patients with endometriosis and associated neuromuscular disease of the gastrointestinal tract.\n\nID: 22061231\nTitle: Contaminant lactic acid bacteria of dry sausages produce histamine and tyramine.\nAbstract: Exogenous biogenic amines present a food poisoning hazard in fermented foods especially with additional risk factors, e.g. amine oxidase inhibiting drugs, alcohol and gastrointestinal diseases. Forty-two lactic acid bacteria (LAB) strains were isolated from seven dry sausages during ripening (0 day, 21 day and 49 day). Their ability to produce histamine and tyramine was studied by HPLC detection from broth cultures after 2 days incubation. The tyramine and histamine concentrations in sausages increased during fermentation. 10 of 42 LAB strains produced 402-1087 ppm tyramine. Four of these 10 contaminant LABs were also histamine-positive (725-1083 ppm). Most of the amine positive strains were found in sausages at the end of ripening and with highest amine levels. On the basis of these results the contaminant LABs play an important role in tyramine and histamine formation during the ripening of dry sausages. Therefore it could be possible to decrease the levels of amines formed by limiting the initial level and growth of these contaminant bacteria.\n\nID: 3283291\nTitle: Antidepressant drug therapy: associated risks.\nAbstract: Aspects of risks associated with treatment with three classes of antidepressants: tricyclic (TCA), second generation (\"new\") antidepressants and monoamine oxidase inhibitor (MAOI), are discussed. Moclobemide, a benzamide derivative, is a new MAOI antidepressant with reversible and preferential inhibition of the A-form of monoamine oxidase. Moclobemide is free of liver toxicity and the risk of a pressor response with tyramine-containing food is so low that strict diet restrictions are unnecessary. That MAOIs have a low incidence of side effects, particularly so called anticholinergic side effects is also true for moclobemide. A serious risk with antidepressant drugs is that the patient will use them to attempt suicide. Therefore important aspects of antidepressants are that they should take effect rapidly and be safe in overdose. No deaths from overdose have been observed with toloxatone, the only reversible MAOI antidepressant on the market to date. It is concluded that the new reversible MAOI antidepressant moclobemide is similar to other antidepressants in terms of efficacy but very noticeably superior in terms of tolerance and safety.\n\nID: 2408831\nTitle: The pharmacological modification of secretory responses.\nAbstract: Electrolyte transport across the intestinal mucosa can be modulated by several neurotransmitters, hormones and drugs. Opiate agonists and endogenous opioid peptides inhibit electrolyte secretion both in vitro and in vivo. These drugs appear to act at several levels. Thus, opioid effects can be elicited at the local mucosal level. Secondly, antisecretory effects can be demonstrated when opioids are administered into the brain. These central effects appear to involve activation of the sympathetic innervation of the intestine. Thirdly, some antidiarrhoeal drugs such as loperamide may have ancillary non-opiate-like actions that contribute to their effectiveness. In cases of inflammatory bowel disease where local concentrations of inflammatory mediators such as kinins and eicosanoids may be high, non-steroidal anti-inflammatory drugs may be effective in treating diarrhoeal symptoms. The existence of many types of receptors on mucosal cells indicates that several pharmacological approaches exist for the potential modulation of electrolyte transport.\n\nID: 6744787\nTitle: Bile salts, hypotension and obstructive jaundice.\nAbstract: We have examined the effects of bile duct ligation on vascular and extravascular smooth muscle responsiveness to noradrenaline and tyramine using isolated rat hindlimb perfusion, and portal vein and vas deferens preparations. Bile duct ligation reduced the contractile responses to noradrenaline of vascular and extravascular smooth muscle. Exposure of smooth muscle to some bile salts caused a reduction in contractility. This effect was dependent upon bile salt type and concentration. These studies in vitro suggest that the reduced total peripheral resistance and hypotension seen in obstructive jaundice cannot be explained by a spasmolytic effect of some of the bile salts on smooth muscle.\n\nID: 7458927\nTitle: Depressed uptake of serotonin by platelets in hepatic encephalopathy.\nAbstract: \n\nID: 389835\nTitle: In vitro adsorption of possible aetiological factors of hepatic encephalopathy.\nAbstract: Four different adsorbents (activated charcoal, XAD-4, a strong base anion and a strong acid cation-exchange resin) were tested in vitro for their capacity to remove substances that may be important in the development of hepatic encephalopathy. Separate columns packed with one of these adsorbents were perfused for three hours with a reconstituted plasma solution containing simultaneously high concentrations of amino-acids, ammoniumchloride, short-chain fatty acids, octopamine and bile salts. Effective removal of all these substances was only obtained when either activated charcoal, or XAD-4, were combined with the cation-exchange resin. Possible implications for the treatment of hepatic coma are discussed.\n\nID: 436292\nTitle: The preparation of 125I-labelled bile acid ligands for use in the radioimmunoassay of bile acids.\nAbstract: A general method for the preparation of 125I-labelled bile acid-histamine or 125I-labelled bile acid-tyramine conjugates is presented. The method is simple, quick and produces ligands in good yield (30%). The characteristics of a radioimmunoassay for conjugated chenodeoxycholic acid, based on an 125I-labelled ligand prepared by the method, are also described. The assay produced values for fasting serum concentrations of conjugated chenodeoxycholic acid that agree well with previous data.\n\nID: 42352465\nTitle: Cervicovaginal Microbiota and Biogenic Amine Metabolic Shifts in HPV-Associated Cervical Disease.\nAbstract: Background: Cervical cancer is primarily caused by the human papillomavirus (HPV), with persistent infections progressing to low- (LGSIL) and high-grade (HGSIL) lesions. Emerging evidence indicates that the cervicovaginal microbiota influences HPV persistence and disease progression, although the underlying metabolic mechanisms remain unclear. Therefore, we assessed the relationship between the cervicovaginal microbiota and the metabolic milieu in women with cervical dysplasia and HPV infections. Methods: We recruited 36 non-menopausal, non-pregnant women who were classified as negative, LGSIL, or HGSIL based on pathology and HPV results. Cervical swabs were collected for genomic DNA extraction to characterize bacterial communities using 16S rRNA sequencing and to perform HPV genotyping. Cervical lavages were collected for untargeted metabolomic profiling using Gas Chromatography-Mass Spectrometry. Integrative multiomic analysis was performed using the MIMOSA2 pipeline. Results: Although bacterial community structure was not different between groups, women with HGSIL had higher richness and exhibited a higher abundance of Prevotella bivia, Prevotella buccalis, and Lachnospiraceae G-9 oral taxon 924. Lesion-positive samples had shifts in tyramine and putrescine, biogenic amines linked to cancer development. Specifically, Pseudomonas was identified as a potential contributor to tyramine oxidation. Conclusions: Cervical lesions and HPV risk are associated with shifts in the cervicovaginal microbial metabolic milieu, highlighting the role of low-abundant anaerobic bacteria. Despite the small sample size, biogenic amines were associated with anaerobic taxa and microbial dysbiosis. These findings warrant further assessment of microbial-derived metabolites and their potential to promote tumor progression by driving a pro-inflammatory, metabolically altered microenvironment.\n\nID: 42283770\nTitle: Divergent Colorectal Cancer Risks Following Metabolic Bariatric Surgery: Anatomical Remodeling and the Genotoxic Microenvironment.\nAbstract: Metabolic bariatric surgery (MBS) reduces overall cancer incidence, yet colorectal cancer (CRC) risk diverges by procedure. Roux-en-Y gastric bypass (RYGB) has been associated with increased long-term CRC risk (HR 1.55 at 10-14 years), whereas sleeve gastrectomy (SG) shows no equivalent elevation, though shorter follow-up (mean 4.5 vs. 8.5 years) precludes definitive conclusions. This review develops a biologically plausible mechanistic framework for these divergent outcomes. RYGB-induced anatomical bypass and accelerated transit are proposed to drive distal substrate overload, with an associated shift of the colonic microbiome toward proteolytic fermentation. The proposed genotoxic luminal environment is characterized by convergent actions of secondary bile acids, tyramine, and hydrogen sulfide, compounded by butyrate depletion. By preserving gastrointestinal continuity, SG is hypothesized to avoid these alterations. These considerations support integrating baseline CRC risk into surgical selection and procedure-specific surveillance after RYGB.\n\nID: 42129938\nTitle: Multi-omics reveals effects of several rumen bacteria on reproductive performance of sheep.\nAbstract: Mounting evidence indicates that the rumen microbiota plays a crucial role in the reproductive health of sheep. However, the potential beneficial effects of rumen microbiota on lambing performance in sheep across different stages of the reproductive cycle and the precise mechanisms underlying these effects remain unclear. We aimed to elucidate the rumen microbial regulatory network underlying differences in reproductive performance in sheep by integrating multi-stage metagenomics and metabolomics. No significant difference was observed in the ruminal microbial α-diversity between sheep with high and low litter size. However, significant stage-specific segregation was observed in their community structures. We identified a cohort of key species strongly associated with litter size. These included Asaia bogorensis, Methanolobus zinderi, Erwinia gerundensis, Marinobacter sp. BSs20148, and Lactobacillus amylolyticus enriched during pregnancy; Rhizobium gallicum, Aeromonas caviae, Pseudolysobacter antarcticus, Mucilaginibacter rubeus, Thermococcus paralvinellae, and Janthinobacterium svalbardensis enriched during lactation; Pseudomonas mandelii, Gordonia sp. HY186, Arachidicoccus sp. BS20, Mesotoga prima, Acidovorax ebreus, Donacia cinerea, and Salmonella enterica enriched during estrus. Host plasma metabolomics analysis further revealed an enrichment of a set of core metabolites in the blood of high-fertility sheep, including Inositol, 2-Linoleoylglycerol, lysophosphatidylcholines and neuromodulatory substances such as tyramine and sphingosine-1-phosphate. We constructed stage-specific \"rumen microbe-rumen metabolite-plasma metabolite\" regulatory axes. These results suggest the influence of the rumen microbiome on plasma metabolic profiles and subsequent fertility outcomes in sheep. We elucidate the dynamic mechanism by which the rumen microbiota in high-fertility sheep is associated with superior reproductive performance through stage-adaptive community succession and functional remodeling, which in turn may modulate the host's neuroendocrine and lipid metabolic profiles. These findings provide a new perspective for understanding the regulation of fertility in ruminants and lay a theoretical foundation for improving reproductive efficiency through nutritional strategies targeting the rumen microbiota.

This study aimed to characterize the gut microbial composition, function, and metabolic profiles in children with NOA using an integrated multi-omics approach. A case-control study was conducted involving 88 children aged 1-5 years (48 NOA, 40 healthy controls). Gut microbiota composition was assessed via 16S rRNA gene sequencing of all fecal samples. Subsequently, the five most representative samples from each group were selected for deep shotgun metagenomic sequencing and liquid chromatography-mass spectrometry (LC-MS) based non-targeted metabolomics. NOA children showed significantly higher microbial richness and diversity (Chao1, Shannon; P < 0.001). The NOA group had elevated Firmicutes, Bacteroidota, Bacteroides, Faecalibacterium, Subdoligranulum, and Roseburia, but reduced Actobacteriota, Bifidobacterium, and Enterococcus. Metagenomics revealed downregulated riboflavin metabolism and upregulated fat digestion/absorption pathways in NOA (P < 0.05). Metabolomics identified 26 differential fecal metabolites, including decreased L-carnitine derivatives and elevated tyramine glucuronide involved in bile secretion. These metabolites were significantly correlated with altered bacterial genera. Our integrated multi-omics analysis demonstrates that NOA in children is associated with a specific gut ecosystem characterized by altered microbiota structure, perturbed microbial metabolic functions (particularly riboflavin metabolism), and corresponding host-microbiota co-metabolic disturbances. These findings provide novel evidence for the disrupted \"microbiota-metabolite\" axis in NOA, offering new mechanistic insights.\n\nID: 42003095\nTitle: Metabolites and Polycystic Ovarian Syndrome: A Mendelian Randomization Study.\nAbstract: Polycystic ovarian syndrome (PCOS) is a common reproductive disorder that affects a considerable number of women worldwide. Nevertheless, the causal relationship between metabolites and PCOS remains undetermined. We utilized a comprehensive two-sample Mendelian randomization (MR) analysis, a genetic epidemiological approach that uses genetic variants as instrumental variables to assess causal relationships between exposures and outcomes, to examine the causal link between 1352 metabolites and PCOS. We employed complementary MR methods, such as the inverse-variance weighted (IVW) method, and conducted sensitivity analyses to evaluate the reliability of the outcomes. Reverse MR analysis was performed to evaluate the possibility of reverse causation. Five metabolites were identified to be significantly associated with PCOS risk: Methionine sulfoxide levels (IVW: OR [95%]: 1.549[1.274 to 1.883], p = 1.154E-5), Theophylline levels (IVW: OR [95%]: 0.725[0.589 to 0.890], p = 0.002), 4-hydroxycoumarin levels (IVW: OR [95%]: 0.786[0.658 to 0.940], p = 0.008), Tyramine O-sulfate levels (IVW: OR [95%]: 0.699[0.568 to 0.862], p = 0.0008), and Sulfate of piperine metabolite C16H19NO3 (3) levels (IVW: OR [95%]: 1.296[1.064 to 1.579], p = 0.009). We found PCOS was significantly associated with decreased Tyramine O-sulfate levels using the IVW method (OR [95%]: 0.953[0.917 to 0.991], p = 0.015) in the reverse MR analysis. The results of the sensitivity analyses were consistent with the main findings. This study establishes causal relationships between specific metabolites and PCOS, highlighting the significant roles of oxidative stress (methionine sulfoxide), dietary components (theophylline, piperine metabolite), and gut microbiome-derived metabolites. These findings provide novel insights into PCOS pathogenesis and identify potential targets for prevention and treatment. However, the study's limitation to European populations necessitates further validation in diverse ethnic groups. Our MR analysis provides strong evidence supporting a causal association between metabolites and the susceptibility of PCOS.\n\nID: 41857429\nTitle: Python metabolomics uncovers a conserved postprandial metabolite and gut-brain feeding pathway.\nAbstract: Most mammals consume small and frequent meals. By contrast, pythons are ambush predators that exhibit extreme feeding and fasting patterns and provide a unique model for uncovering molecular mediators of the postprandial response1-3. Using untargeted metabolomics, we show that circulating levels of the metabolite para-tyramine-O-sulphate (pTOS) are increased more than 1,000-fold in pythons after a single meal. In pythons, pTOS production occurs in a microbiome-dependent manner via sequential decarboxylation and sulphation of dietary tyrosine. In both pythons and mice, pTOS administration activates a neural population in the ventromedial hypothalamus (VMH). In mice, these VMH neurons are required for the anorexigenic effects of pTOS. Chronic administration of pTOS to diet-induced obese male mice suppresses food intake and body weight. pTOS is also present in human blood, where its levels are increased after a meal. Together, these data uncover a conserved postprandial anorexigenic metabolite that links nutrient intake to energy balance.\n\nID: 41840712\nTitle: Characterization of age-related changes in the gut microbiome and metabolome of Kunming dogs and their associations with police performance.\nAbstract: Gut microbiota plays a pivotal role in regulating the host's central nervous system (CNS) activity and behavior. However, its influence on the police performance of Kunming dogs and the underlying mechanisms remain largely unexplored. This study was the first to apply multi-omics technologies to investigate the dynamic variations in gut microbiota and their metabolic profiles across different ages of Kunming dogs. Furthermore, we systematically examined the associations between these microbial alterations and police performance metrics, providing a theoretical foundation for enhancing the working capabilities of Kunming dogs through targeted modulation of intestinal microecology. The study showed that puppies, young dogs and adult dogs had significantly better police performance than elderly dogs, with young dogs exhibiting the highest scores. Analysis of 16S rRNA sequencing demonstrated that gut microbial diversity and stability were highest during the young dog stage, gradually declining with age. Metagenomic analysis revealed that the abundance of Lactobacillus acidophilus, Lactobacillus johnsonii, Limosilactobacillus reuteri, Ligilactobacillus animalis and Muribaculum gordoncarteri were strongly correlated with police performance. The results of metagenome-assembled genomes (MAGs) indicated that the above species have functional genes involved in GABAergic and glutamatergic synapse pathways. Furthermore, metabolomic analysis showed that differential metabolites were enriched in the neuroactive ligand-receptor interaction pathway, in which GABA (γ-aminobutyric acid), histamine and tyramine metabolites were positively correlated with the above species and police performance. The species L. acidophilus, L. johnsonii, L. reuteri, L. animalis, and M. gordoncarteri, which were enriched in the gut of puppies and young Kunming dogs, may potentially influence the nervous system through the production of neurotransmitters and neuromodulators, suggesting a possible association with police performance. Video Abstract.\n\nID: 41722523\nTitle: Comprehensive analysis of spoilage characteristics of refrigerated hairtail by microbiome and metabolomics.\nAbstract: Hairtail is prone to spoilage during refrigerated storage and it is due to microbial activity, which will directly lead to changes in the composition of metabolites in vivo. This study systematically elucidates the spoilage phenomena in hairtail during eight days of refrigeration at 4 °C through multi-omics analysis. Pseudomonas and Shewanella were identified as key spoilage bacteria, and their nutrient utilization pathways were different Pseudomonas dominated the early stage and used monosaccharides; however, Shewanella appeared in the later stage, and its metabolism is heavily dependent on amino acids and nitrogen-containing compounds such as TMAO released in large quantities in the later stage of spoilage. Non-targeted metabolomics results revealed a total of 62 differentially expressed metabolites. Metabolic pathway enrichment analysis revealed that cysteine and methionine metabolism, tyrosine metabolism and nucleotide metabolism played pivotal roles in the putrefaction process. Moreover, the study identified 7 metabolites (such as Lys-Met, Nicotinic Acid Adenine Dinucleotide) that showed a significant correlation with the dominant spoilage bacterium Pseudomonas through correlation analysis; while two other metabolites (such as Inosine 5'-Monophosphate, Tyramine) were significantly correlated with the primary spoilage bacterium Shewanella. The integration of microbiome and metabolomics analyses has enabled the precise identification of key spoilage microorganisms and metabolites in chilled hairtail, providing crucial evidence for developing targeted preservation techniques.\n\nID: 41615647\nTitle: Correlation analysis of gut microbiota and metabolites in gastric cancer patients in plateau areas based on multi-omics technologies.\nAbstract: To characterize gut microbiota alterations and metabolic changes in gastric cancer (GC) patients from high-altitude regions using 16S rDNA sequencing and untargeted metabolomics. Fecal samples from 30 GC patients and 30 healthy controls in Qinghai Province were analyzed. Microbial diversity and composition were assessed via 16S rDNA sequencing, and metabolite profiles were determined using untargeted metabolomics. Correlations between significantly altered microbial taxa and metabolites were evaluated. Microbial diversity differed significantly between groups (P < 0.001). Proteobacteria abundance was higher in GC patients (P < 0.05). At the genus level, Prevotella_9, Streptococcus, and Lactobacillus showed significant differences (P < 0.05-P < 0.001). GC patients exhibited upregulation of desulfo-biotin, glycylproline, glycine, hydroxyhexanoic acid, tyramine, methanethiol oxidase, 5-aminopentanoic acid, citrulline, betaine, and formyl glutamic acid, and downregulation of cytidine, 5'-methylthioadenosine, trehalose, melezitose, lotaustralin, adenosine, creatinine, 5-methyluridine, raffinose, and galactitol. Proteobacteria correlated positively with desulfo-biotin, glycylproline, and glycine, while Lactobacillus correlated with several upregulated metabolites including tyramine and betaine (all P < 0.05). Cytidine correlated negatively with Proteobacteria, whereas creatinine and 5-methyluridine correlated positively with Prevotella_9. GC patients in high-altitude regions display distinct gut microbiota and metabolite profiles, with notable microbe-metabolite associations. These findings suggest potential biomarkers and therapeutic targets for GC in plateau populations.\n\nID: 41552834\nTitle: A sulfotransferase from a gut microbe acts on diverse phenolic sulfate compounds, including acetaminophen sulfate.\nAbstract: Sulfonation is one of the two main phase II detoxification pathways in eukaryotes which transforms nonpolar compounds into hydrophilic metabolites. Sulfotransferases catalyze these reactions by transferring a sulfo group from a donor to an acceptor molecule. Human cytosolic sulfotransferases use only 3'-phosphoadenosine 5'-phosphosulfate (PAPS) as a donor to sulfonate a variety of chemicals. Less understood are microbial aryl-sulfate sulfotransferases (ASSTs), which catalyze sulfo transfer reactions, without utilizing PAPS as a donor. Currently, the identity of physiological sulfo donor substrates remains unknown and sulfo acceptor substrates are underexplored. With this study, we aim to understand the potential contribution of a gut microbial enzyme to sulfonation chemistry by uncovering its substrate preferences. Here, we show that a sulfotransferase (Bacteroides vulgatus ASST) from the prevalent gut microbe B. vulgatus (now Phocaeicola vulgatus) is a versatile catalyst that utilizes a wide range of phenolic molecules as substrates that are commonly encountered by the host. With this action, it modulates concentrations of donor phenolic sulfates such as acetaminophen sulfate, dopamine sulfate, p-cresol sulfate, and related compounds in vitro and displays broad acceptor flexibility by sulfonating diverse phenolic compounds, including p-coumaric acid, p-cresol, 4-ethylphenol, tyramine, among others. These findings suggest that gut microbial enzymes like ASSTs may contribute to host detoxification of phenolics, a role previously attributed solely to human sulfotransferases. However, further in vivo studies are necessary to understand the potential contributions of ASSTs to host detoxification processes.\n\nID: 41542410\nTitle: Python metabolomics uncovers a conserved postprandial metabolite and gut-brain feeding pathway.\nAbstract: Most mammals consume small and frequent meals.

Although long considered products of host metabolism, these aromatic monoamines are now also known to originate in part from the microbiota, where they are synthesized by bacterial aromatic L-amino acid decarboxylases (AADCs). This review explores the distribution, biochemical diversity, and host interactions of microbiota-encoded AADCs, highlighting their roles in gut and skin ecosystems. Bacterial AADCs vary in gene organization, substrate range, and expression patterns across taxa like Ruminococcus gnavus, Clostridium sporogenes, Enterococcus spp., and Staphylococcus spp. These enzymes contribute to microbial fitness through acid stress resistance, energy generation via proton motive force, epithelial adherence and internalization, and niche dominance. Critically, their products modulate host physiology via trace amine-associated receptors (TAARs) and other signaling pathways, influencing neurotransmission, immune response, barrier integrity, and metabolism. Microbiota-derived monoamines can enter systemic circulation and cross the blood-brain barrier, implicating them in disorders ranging from irritable bowel syndrome to neurodegeneration. Emerging data also reveal their impact on wound healing and drug efficacy, notably in Parkinson's disease. By positioning microbial AADCs as key players in host-microbe chemical communication, this review underscores their relevance for health and disease and highlights them as potential therapeutic targets.\n\nID: 40920667\nTitle: Effects of yeast beta-1,3/1,6-glucans on nutrient digestibility, intestinal functionality, and immune and antioxidant variables in growing dogs submitted to spay or neutering surgery.\nAbstract: This study aimed to assess the impact of yeast beta-1,3/1,6-glucans (BG) on apparent digestibility coefficients (ADC) of nutrients, intestinal fermentative metabolites, fecal microbiota profile, and immune and antioxidant variables in puppies before and after surgical challenge. Two treatments were evaluated: control, without, and test, with oral supplementation of 65 mg/kg body weight/day of purified BG from Saccharomyces cerevisiae for 120 days. For this, 16 growing Beagle dogs were distributed in a completely randomized design (n = 8/treatment). On day 31, dogs were submitted to spay or neutering surgery. Diet ADC and fecal characteristics analyses were performed on days 55-60. Fecal (days 0, 15, 30, 34, and 60) and blood (days 0, 30, 34, and 60) samples were collected to evaluate intestinal fermentative metabolites, fecal IgA and microbiota, intestinal permeability, and immune and antioxidant variables. On day 80, all dogs were vaccinated for rabies and blood samples were collected on day 120 to determine antibody titers. The supplementation of BG promoted an increase in fecal IgA concentrations on day 15 (P < 0.05) and an increase in fecal concentrations of butyrate (P < 0.05) when day 30 minus day 0 were compared. Dogs of the BG group presented higher fecal concentrations of serotonin (day 15), spermidine (days 15, 30, and 34), and a reduction in tyramine, histamine, and cadaverine on day 60 (P < 0.001). BG consumption promoted an increase in richness and a clear differentiation in the fecal microbiota profile on days 34 and 60 (P < 0.05). BG group also presented an increase in fecal Faecalibacterium, Blautia, and Turicibacter on day 34 (P < 0.05). Reduced glutathione and catalase activities were higher in the BG group (P < 0.05), regardless of the day. In conclusion, the supplementation of BG does not alter the ADC of nutrients, beneficially modulates the intestinal functionality, and stimulates the activity of antioxidant enzymes in growing dogs submitted to a surgical challenge.\n\nID: 40838741\nTitle: Serotonergic and immunomodulatory properties of the psychobiotic candidate Bacteroides finegoldii UO.H1052 and its extracellular vesicles.\nAbstract: Bacteroides finegoldii UO.H1052, a human gut commensal, was evaluated for its potential psychobiotic and immunomodulatory properties. Whole-genome analysis confirmed the absence of virulence factors, plasmids, and antibiotic-resistance genes. Metabolomic profiling of cell-free supernatants (CFSs) and extracellular vesicle (EV) postbiotics revealed a high- and medium-dependent production of neuroactive metabolites, including γ-aminobutyric acid, tryptophan, tyrosine, and tyramine, as well as physiologically relevant levels of short-chain fatty acids, such as acetate, propionate, and butyrate. Functionally, CFS enhanced epithelial barrier integrity by increasing transepithelial electrical resistance and mitigating LPS-induced disruption in Caco2/HT29 monolayers without cytotoxic effects. Both CFS and EVs exhibited immunomodulatory properties, characterized by elevated Il-10/Tnf-α ratios under basal conditions and significant suppression of Tnf-α expression in LPS-stimulated RAW 264.7 macrophages. Notably, CFS and EVs increased tryptophan hydroxylase 1 (Tph1) gene expression in enterochromaffin RIN14B cells by 6.6- and 3.2-fold, respectively, suggesting enhanced serotonergic activity. These findings highlight B. finegoldii UO.H1052 as a promising next-generation psychobiotic candidate with neuroactive, barrier-protective, and immunoregulatory properties, supporting its potential for gut-brain axis modulation. Emerging evidence supports the critical role of the gut microbiota in modulating host neurophysiology and immune function via the gut-brain axis. Here, we present a comprehensive characterization of Bacteroides finegoldii UO.H1052, a human gut commensal that exhibits promising psychobiotic attributes, including the production of neuroactive compounds and extracellular vesicles (EVs) with immunoregulatory and serotonin-inducing properties. The strain exhibits a favorable safety profile, with no detected virulence factors or transmissible antibiotic resistance. Importantly, cell-free supernatants and EVs enhanced epithelial barrier integrity, modulated pro- and anti-inflammatory cytokine responses, and significantly upregulated the expression of Tph1, a key enzyme in serotonin biosynthesis. These findings underscore the potential of B. finegoldii UO.H1052 as a next-generation psychobiotic candidate and highlight EVs as effective postbiotic mediators of host-microbe communication. This study advances the understanding of Bacteroides-derived psychobiotics and provides a foundation for their development in modulating gut-brain and immune pathways relevant to neuroinflammatory and gastrointestinal disorders.\n\nID: 40647126\nTitle: Apple Juice Fermented with Lactiplantibacillus plantarum Improves Its Flavor Profile and Probiotic Potential.\nAbstract: Fermented apple juice (FAJ), a nutrient-dense beverage rich in vitamins, offers multiple health benefits, including improved digestion, enhanced fat metabolism, and sustained energy provision with reduced caloric intake. To advance the development of probiotic-enriched flavored and functional juices, this study establishes Lactiplantibacillus plantarum (L. plantarum) as a safe and effective starter culture for apple juice fermentation. The selected strain exhibited minimal biogenic amine synthesis, producing only 30.55 ± 1.2 mg/L of putrescine and 0.59 ± 0.55 mg/L of cadaverine, while histamine and tyramine were undetectable. Furthermore, the strain demonstrated no hemolytic activity and exhibited robust biofilm-forming capacity, reinforcing its suitability for fermentation applications. An electronic nose analysis revealed that L. plantarum significantly enriched the volatile compound profile of FAJ, leading to an improved flavor profile. The strain also displayed excellent growth adaptability in the apple juice matrix, further optimizing fermentation efficiency and sensory quality. Crucially, 16S rRNA sequencing demonstrated that FAJ specifically restructures the gut microbiota in obese individuals, significantly elevating the relative abundance of beneficial genera, including Enterococcus, Parabacteroides, and Bifidobacterium (p < 0.05). Concurrently, FAJ enhanced glycolytic activity, suggesting a potential role in metabolic regulation. Collectively, these findings confirm that L. plantarum-fermented FAJ combines favorable sensory properties and safety with promising anti-obesity effects mediated through gut microbiome modulation and metabolic pathway activation. This study provides a critical scientific foundation for designing next-generation functional fermented beverages with targeted health benefits.\n\nID: 40646988\nTitle: Integrated Microbiome and Metabolomics Insights into Meat Quality Changes in Rice-Field Eel Slices During Refrigeration Storage: Effects of ε-Polylysine, Vitamin C, Epigallocatechin Gallate, and Phloretin.\nAbstract: Rice-field eel (Monopterus albus) slices, an important aquatic product in Southeast Asia, are prone to spoilage and deterioration during cold chain storage. In this study, the effects of a composite preservative (ε-polylysine, Vitamin C (Vc), epigallocatechin gallate (EGCG), and phloretin) on the muscle quality (color, texture, water holding capacity (WHC)) of rice-field eel slices during refrigeration storage at 4 °C for up to 7 days was investigated, and the underlying mechanism was elucidated by the integrated microbiome and metabolomics, in addition to Elisa and Low-Field Nuclear Magnetic Resonance (LF-NMR). After 7 days of storage, the WHC, shear force, and a* decreased by 11.39%, 34.37%, and 49.20% in treated samples, and by 19.18%, 38.38%, and 54.87% in control samples, respectively. The addition of the composite preservative significantly increased Hexokinase, Pyruvate kinase, and Creatine kinase, while it decreased the total viable count (TVC), total volatile basic nitrogen (TVB-N), thiobarbituric acid reactive substance (TBARS), and Lactic acid. Preservative treatment maintained the moisture content of the eel slices during storage and prevented bright red oxymyoglobin from transforming into brown metmyoglobin. Microbiota composition (especially Pseudomonas) and metabolic pathways (including amino acid and its metabolites, nucleotide and its metabolite, and organic acid and its derivatives, etc.) were obviously altered by the preservative treatment. Pseudomonas, tryptophan-aspartic acid (Trp-Asp), D-Glucose 6-phosphate, Succinic Acid, Biliverdin 1, 5-Diaminopentane, and Tyramine, etc., are potential biomarkers for the quality changes of eel slices during refrigeration. These findings provide an in-depth understanding of the improvement of the eel slice quality during refrigeration storage by the composite preservative.\n\nID: 40394473\nTitle: Modulating autism spectrum disorder pathophysiology using a trace amine-focused approach: targeting the gut.\nAbstract: Autism spectrum disorder (ASD) affects approximately 1% of the population directly, but also a much higher proportion (family and caregivers) indirectly. Although ASD is characterized by high prevalence of anxiety and poor gastrointestinal health, current treatment strategies are mainly focused on neurological symptomatic treatment, with little to no attention to gut health. Furthermore, many psychiatric drugs used for management of secondary neurological symptoms, are known to exacerbate gut health issues and neurological dysregulation across the gut-brain axis.Trace amines are neurotransmitter-like substances synthesized endogenously in the human brain - in trace amounts - but also in high abundance by the microbiome. Emerging evidence suggests dysregulation of the trace amine system in ASD. Since trace aminergic signalling is central to regulatory system homeostasis, we hypothesize targeting this system in the ASD context. Given the various sources of trace amines, we suggest that normalization of functional dysbiosis in terms of trace aminergic signalling - rather than microbial compositional dysbiosis - should be a focus in medicines development. In addition, a holistic consideration including also other factors at play in determining trace aminergic signalling outcome - such as receptor binding, enzymatic role players, etc. - is required to fully elucidate and therapeutically modify the pathophysiology of regulatory systems implicated in ASD.This review firstly provides a brief overview of trace amine dysregulation in ASD for context. Secondly, we formulate our hypothesis on how this may therapeutically address symptomology, with consideration of cellular and molecular mechanism interplay across the gut-brain axis. Finally, we provide a critical assessment of advances in therapeutics development and drug re-purposing, gaps in knowledge and priorities for medicines development going forward.\n\nID: 40362077\nTitle: Preliminary Multi-Omics Insights into Green Alternatives to Antibiotics: Effects of Pulsatilla chinensis, Acer truncatum, and Clostridium butyricum on Gut Health and Metabolic Regulation in Chickens.\nAbstract: Antibiotic resistance has become a global health concern, driving the need for sustainable alternatives in animal husbandry. This study explores the potential of natural feed additives as a viable solution to enhance poultry growth and health while reducing reliance on antibiotics. Chinese herbal medicines and probiotics have been widely studied as green, healthy, and safe antibiotic alternatives in livestock and poultry production. A total of 120 chickens were randomly divided into four groups: a control group and three treatment groups supplemented with 1% Pulsatilla chinensis powder, 3% fresh Acer truncatum, or 1% Clostridium butyricum. The results showed that Pulsatilla chinensis powder significantly increased gamma-glutamylcysteine (p < 0.05), UDP-N-acetylglucosamine (p < 0.05), tyramine (p < 0.01), and leucine (p < 0.05). Acer truncatum notably altered cecal metabolites, including L-tyrosine (p < 0.05), α-ketoisovaleric acid (p < 0.01), myristoleic acid (p < 0.01), glutathione (p < 0.05), and PGA1 (p < 0.05). Clostridium butyricum modified cecal metabolites such as L-glutamine (p < 0.05), riboflavin (p < 0.05), L-Carnitine (p < 0.05), ergocalciferol (p < 0.01), and α-tocotrienol (p < 0.05).\n\nID: 40306360\nTitle: Biogenic amines in honey bee cognition: neurochemical pathways and stress impacts.\nAbstract: Honey bees, as indispensable pollinators, rely on sophisticated neuromodulatory networks to regulate learning, memory, and social behaviors, all essential for colony function, ecosystem stability, and global agricultural systems. Biogenic amines octopamine, dopamine, serotonin, and tyramine are key modulators of these cognitive and behavioral processes, regulating foraging efficiency, navigational precision, and division of labor. However, we argue that anthropogenic stressors, including pesticides, pollutants, heavy metals, and microbiome dysbiosis, disrupt aminergic pathways by impairing neurotransmitter synthesis and neuronal signaling, leading to maladaptive behaviors and colony collapse. Recent discoveries expand this paradigm, revealing those biogenic amines in floral nectar act as exogenous neurochemicals, potentially altering pollinator behavior; however, their interaction with agrochemicals remains underexplored. While most studies focus on Apis mellifera, we caution that cautious extrapolation to wild and solitary bees is critical, given the evolutionary conservation of aminergic signaling across insect taxa. Cognitive deficits observed in managed honeybees likely extend to wild pollinators, threatening pollination network resilience and food security. To address these gaps, we advocate for CRISPR-based neurogenetic tools and multi-omics approaches to dissect stress susceptibility and biogenic amine (BA) regulation. Integrating neurobiology, ecotoxicology, and conservation science is imperative to develop precision strategies that mitigate anthropogenic threats, safeguard biodiversity, and stabilize global agriculture.\n\nID: 40284247\nTitle: Selective Influence of Hemp Fiber Ingestion on Post-Exercise Gut Permeability: A Metabolomics-Based Analysis.\nAbstract: Objectives: This study investigated the effects of 2-week ingestion of hemp fiber (high and low doses) versus placebo bars on gut permeability and plasma metabolite shifts during recovery from 2.25 h intensive cycling. Hemp hull powder is a rich source of two bioactive compounds, N-trans-caffeoyl tyramine (NCT) and N-trans-feruloyl tyramine (NFT), with potential gut health benefits. Methods: The study participants included 23 male and female cyclists. A three-arm randomized, placebo-controlled, double-blind, crossover design was used with two 2-week supplementation periods and 2-week washout periods. Supplement bars provided 20, 5, or 0 g/d of hemp hull powder. Participants engaged in an intensive 2.25 h cycling bout at the end of each of the three supplementation periods. Five blood samples were collected before and after supplementation (overnight fasted state), and at 0 h-, 1.5 h-, and 3 h-post-exercise. Five-hour urine samples were collected pre-supplementation and post-2.25 h cycling after ingesting a sugar solution containing 5 g of lactulose, 100 mg of 13C mannitol, and 1.9 g of mannitol in 450 mL of water. An increase in the post-exercise lactulose/13C mannitol ratio (L:13CM) was used as the primary indicator of altered gut permeability. Other outcome measures included muscle damage biomarkers (serum creatine kinase, myoglobin), serum cortisol, complete blood cell counts, and shifts in plasma metabolites using untargeted metabolomics. Results: No trial differences were found for L:13CM, cortisol, blood cell counts, and muscle damage biomarkers. Orthogonal partial least-squares discriminant analysis (OPLSDA) showed distinct trial differences when comparing high- and low-dose hemp fiber compared to placebo supplementation (R2Y = 0.987 and 0.995, respectively). Variable Importance in Projection (VIP) scores identified several relevant metabolites, including 3-hydroxy-4-methoxybenzoic acid (VIP = 1.9), serotonin (VIP = 1.5), 5-hydroxytryptophan (VIP = 1.4), and 4-methoxycinnamic acid (VIP = 1.4). Mummichog analysis showed significant effects of hemp fiber intake on multiple metabolic pathways, including alpha-linolenic acid, porphyrin, sphingolipid, arginine and proline, tryptophan, and primary bile acid metabolism. Conclusions: Hemp fiber intake during a 2-week supplementation period did not have a significant effect on post-exercise gut permeability in cyclists (2.25 h cycling bout) using urine sugar data. On the contrary, untargeted metabolomics showed that the combination of consuming nutrient-rich hemp fiber bars and exercising for 135 min increased levels of beneficial metabolites, including those derived from the gut in healthy cyclists.\n\nID: 40004997\nTitle: Dietary Patterns and Migraine: Insights and Impact.\nAbstract: Migraine is a prevalent neurological disorder characterized by significant disability and triggered by various factors, including dietary habits. This review explores the complex relationship between diet and migraine, highlighting both triggering and protective roles of dietary patterns and specific nutrients. Evidence suggests that certain foods, such as alcohol, caffeine, chocolate, MSG, nitrates, and tyramine, can trigger migraines in susceptible individuals. Conversely, dietary interventions, including carbohydrate-restricted diets, ketogenic diets, vitamin D3 supplementation, omega-3 fatty acids, Mediterranean dietary patterns, and increased water intake, have shown potential in reducing migraine frequency and severity. Observational studies also indicate that maintaining a healthy diet, rich in fruits and vegetables and low in processed foods, is associated with better migraine outcomes. The effectiveness of these interventions varies among individuals, underscoring the importance of personalized approaches. Future studies should further explore the role of diet in migraine management, focusing on randomized trials to establish causality and refine dietary recommendations for patients.\n\nID: 40001178\nTitle: Study on the mechanism of Shuanghe decoction against steroid-induced osteonecrosis of the femoral head: insights from network pharmacology, metabolomics, and gut microbiota.\nAbstract: Steroid-induced osteonecrosis of the femoral head (SONFH) is a challenging and debilitating orthopedic condition with a rising incidence in recent years. Shuanghe Decoction (SHD), a traditional Chinese medicine formula, has shown significant efficacy in treating SONFH, though its underlying mechanisms remain unclear. This study aims to elucidate the therapeutic effects and potential mechanisms of SHD on SONFH through in vivo experiments, combined with network pharmacology, metabolomics, and gut microbiota analysis. Forty male Sprague-Dawley rats (300 ± 20 g) were randomly assigned to four groups: Control, Model, SHD-L, and SHD-H, with 10 rats each. SONFH was induced in all groups except the Control group using lipopolysaccharide and methylprednisolone. The SHD-L and SHD-H groups were treated with Shuanghe decoction at doses of 4.86 g/kg/day and 9.72 g/kg/day, respectively, for eight weeks. Bone morphology, pathological changes, and osteogenic factors were evaluated using Micro-CT, histological staining, and immunohistochemistry. Network pharmacology, metabolomics, and gut microbiota analyses were conducted to explore SHD's mechanisms. SHD improved bone morphology and increased osteogenic factor expression (RUNX2, OCN, COL-I). Network pharmacology indicated that metabolic pathways play a key role in SHD's therapeutic effects. Metabolomic analysis identified 14 differential metabolites, including 21-hydroxypregnenolone and tyramine, which were restored to normal levels by SHD. Gut microbiota analysis revealed that SHD modulated bacterial abundance, particularly Verrucomicrobia, Allobaculum, and Burkholderiales. A comprehensive network identified two key metabolites (tyramine, 21-hydroxypregnenolone), seven targets (CYP19A1, CYP1A2, CYP1B1, CYP2C9, CYP3A4, MIF, and HSD11B1), two metabolic pathways (tyrosine metabolism, steroid hormone biosynthesis), and four bacterial taxa (Jeotgalicoccus, Clostridium, Corynebacterium, rc4-4) as central to SHD against SONFH. SHD alleviates SONFH by reshaping gut microbiota, reversing metabolic imbalances, and enhancing osteogenesis. Our findings provide novel insights into the pharmacological mechanisms of SHD, laying a foundation for its clinical application in treating SONFH.\n\nID: 39963326\nTitle: Dysbiosis and Metabolic Dysregulation of Salivary Microbiota in Schizophrenia.\nAbstract: Schizophrenia (SZ) is a chronic, severe mental disorder that presents significant challenges to diagnosis and effective treatment. Emerging evidence suggests that gut microbiota may play a role in the disease's pathogenesis. However, fewer studies have directly investigated the potential links between oral microbiota and SZ. This study aimed to explore the relationship between salivary microbiota dysbiosis and SZ, examining microbial and metabolic alterations that may contribute to SZ pathophysiology. Salivary samples from 30 hospitalized patients diagnosed with SZ and 10 healthy controls were collected. The microbial and metabolic profiles were analyzed using 16S rRNA gene sequencing and metabolomic profiling. Clinical parameters, including oral health status, were also evaluated to minimize variability in sampling. Patients with SZ exhibited significantly poorer oral health compared to healthy controls, with more missing teeth and worse periodontal status. Microbiota sequencing revealed notable alterations in the overall structure and composition of the salivary microbiome in SZ patients, characterized by increased abundance of specific genera such as Neisseria and Porphyromonas. Metabolomic analysis indicated significant differences between the SZ and control groups, with upregulation of key metabolic pathways, including \"β-alanine metabolism\" and \"vitamin digestion and absorption\". Correlations between microbial dysbiosis and elevated levels of certain metabolites, such as L-methionine sulfoxide (L-MetO) and tyramine, were observed, suggesting links to oxidative stress. The study highlights the presence of significant dysbiosis and metabolic dysfunction in the salivary microbiota of SZ patients, suggesting that alterations in the oral microbiome may contribute to SZ pathogenesis. These results provide new insights into potential diagnostic biomarkers and therapeutic targets for SZ. Further studies with larger sample sizes are required to validate these findings.\n\nID: 39684925\nTitle: Functional Analysis of TAAR1 Expression in the Intestine Wall and the Effect of Its Gene Knockout on the Gut Microbiota in Mice.\nAbstract: Currently, the TAAR1 receptor has been identified in various cell groups in the intestinal wall. It recognizes biogenic amine compounds like phenylethylamine or tyramine, which are products of decarboxylation of phenylalanine and tyrosine by endogenous or bacterial decarboxylases. Since several gut bacteria produce these amines, TAAR1 is suggested to be involved in the interaction between the host and gut microbiota. The purpose of this present study was to clarify the TAAR1 function in the intestinal wall and estimate the TAAR1 gene knockout effect on gut microbiota composition. By analyzing public transcriptomic data of the GEO repository, we identified TAAR1 expression in enterocytes, enteroendocrine cells, tuft cells, and myenteric neurons in mice. The analysis of genes co-expressed with TAAR1 in enteroendocrine cells allows us to suggest the TAAR1 involvement in enteroendocrine cell maturation. Also, in myenteric neurons, we identified the co-expression of TAAR1 with calbindin, which is specific for sensory neurons. The 16S rRNA gene-based analysis of fecal microbiota revealed a slight but significant impact of TAAR1 gene knockout in mice on the gut microbial community, which manifests in the higher diversity, accompanied by low between-sample variability and reorganization of the microbial co-occurrence network.\n\nID: 39668719\nTitle: Digging deep for nutrients and metabolites derived from high dietary protein intake and their potential functions in metabolic health.\nAbstract: Intake of high quantities of dietary proteins sourced from dairy, meat or plants can affect body weight and metabolic health in humans. To improve our understanding of how this may be achieved, we reviewed the data related to the availability of nutrients and metabolites in the faeces, circulation and urine. All protein sources (≥20% by energy) increased faecal levels of branched-chain fatty acids and ammonia and decreased the levels of butyrate. Some metabolites responded to dairy and meat proteins (branched-chain amino acids) as well as dairy and plant proteins (p-cresol), which were increased in faecal matter. Specific to dairy protein intake, the faecal levels of acetate, indole and phenol were increased, whereas plant protein intake specifically increased the levels of kynurenine and tyramine. Meat protein intake increased the faecal levels of methionine, cysteine and alanine and decreased the levels of propionate and acetate. The metabolite profile in the faecal matter following dairy protein intake mirrored availability in circulation or urine. These findings provide an understanding of the contrasting gut versus systemic effects of different dietary proteins, which we know to show different physiological effects. In this regard, we provide directions to determining the mechanisms for the effects of different dietary proteins.\n\nID: 39638856\nTitle: Brain physiology during photoperiod-related caste determination in the primitively eusocial wasp Polistes jokahamae.\nAbstract: Adult females of the primitively eusocial wasp Polistes jokahamae can change caste in response to photoperiod length. Short-day photoperiod females store more lipids but have less developed ovaries for hibernation (becoming gynes), whereas long-day photoperiod females have fewer lipid stores but more developed ovaries under queenless conditions (becoming egg-laying workers). To explore the physiological mechanisms underlying photoperiod-related caste determination, analyses of gene expression levels in the brains of short- or long-day females were performed. Results suggest that short-day females may exhibit higher expression of genes involved in tryptophan metabolism, insulin signaling, and nutrition, including the digestion of sugars and lipids, and production of royal jelly proteins. Oral administration of tryptophan resulted in a positive correlation between tryptophan levels in the brain and lipid stores in the abdomen, suggesting that tryptophan promotes lipid storage in gynes. Long-day females showed enhanced expression of genes involved in tyramine/dopamine syntheses, epidermal growth factor receptor, insulin degradation, and oogenesis. In these females, tyramine administration increased the brain levels of tyramine and dopamine, and activated initial ovarian development under queenless conditions. Together, these results indicate that photoperiod-related caste determination in P. jokahamae may involve gene expression pathways similar to those involved in caste determination during the preimaginal stage in other Polistes species.\n\nID: 39593339\nTitle: Provolone del Monaco PDO cheese: Lactic microflora, biogenic amines and volatilome characterization.\nAbstract: One commercial production run of Provolone del Monaco - a long-ripened pasta filata cheese - was followed up to the end of ripening for a total of 20 samples. 371 LAB isolates were subject to genetic characterization followed by 16S rRNA gene sequencing. The dominant species were Lacticaseibacillus casei/paracasei (19.4 %), Streptococcus macedonicus (19.1 %) and Enterococcus faecalis (13.2 %). Strains were screened for features of technological interest or safety relevance. Tyramine-producing cultures were quite common, above all within enterococci. By MALDI TOF Mass Spectrometry, one Lactococcus lactis and one Enterococcus faecium strain proved to be bacteriocin producers. Four further cheese wheels from the same production run at 623 days of ripening were evaluated for volatile organic compounds, biogenic amines, and bacterial community by metagenomic sequencing. Three individual wheel samples shared a rather similar microbiome with Lactobacillus delbrueckii and Streptococcus thermophilus as the most represented species, while the fourth wheel appeared wholly different being dominated by Lentilactobacillus buchneri and St. infantarius. Additionally, this sample had the greatest content of biogenic amines and a different VOCs composition. Given the variance seen among cheese wheels processed and ripened under the same conditions, the search for adjunct cultures in the production of this cheese seems to be of utmost importance.\n\nID: 39457871\nTitle: GnRH Immunocastration in Male Xizang Sheep: Impacts on Rumen Microbiome and Metabolite Profiles for Enhanced Health and Productivity.\nAbstract: Castration is a prevalent and indispensable practice in sheep husbandry, aiding in enhancing meat quality, mitigating aggressive behavior, and managing unwanted reproduction. Nevertheless, the conventional surgical castration procedure poses several challenges, including heightened stress and pain, detrimental impacts on animal welfare, and diminished economic efficacy in farming operations. Consequently, immunocastration methods, serving as substitutes for surgical castration, are progressively finding application in livestock. The rumen, an essential and distinctive digestive and absorptive organ in ruminants, has been associated with enhanced meat quality and productive performance following castration in previous research studies, albeit fewer investigations have explored the potential impacts of GnRH immunization on the rumen's internal milieu in sheep post-de-escalation. Hence, the present study delved into evaluating the impact of GnRH immunocastration on the rumen microbiome and metabolomics in male Xizang sheep. This was achieved through the establishment of a GnRH immunocastration animal model and the collection of rumen fluid for microbiological and comprehensive metabolomics investigations. The outcomes of this investigation unveiled that the impact of GnRH immunocastration on body weight gain was more pronounced during the achievement of the castration objective. In addition, the Firmicutes-to-Bacteroidota ratio in the immune male (IM) group exceeded that of the control group (EM), suggesting that GnRH immunodeficiency may enhance the digestion and absorption of feed in male Xizang sheep. At the taxonomic level, the elevated presence of Prevotella and Quinella bacteria in the IM group compared to the EM group indicated that castration influenced a segment of the rumen microbiota in male Xizang sheep, thereby bolstering the digestive and metabolic efficacy of the rumen concerning nutrient utilization, particularly in the breakdown and absorption of proteins, carbohydrates, and lipids, ultimately expediting the fattening process and weight gain in male Xizang sheep following castration. Moreover, analysis of ruminal fluid metabolomics revealed that GnRH immunization had notable impacts on certain metabolites in the ruminal fluid of male Xizang sheep, with metabolites like 5-hydroxyindole acetic acid and 3-hydroxyindole acetic acid showing significant downregulation in the IM group compared to the EM group, while niacin and tyramine exhibited significant upregulation. These findings indicate a profound influence of GnRH immunization on the maintenance of ruminal equilibrium and ruminal health (including the health of ruminal epithelial cells). This study validates that GnRH immunocastration not only achieves the objectives of castration but also enhances ruminal health in male Xizang sheep, thus laying a foundational theoretical basis for the application and dissemination of GnRH immunocastration technology.\n\nID: 42314521\nTitle: Maternal egg yolk supplementation alters offspring liver choline status and is associated with functional network activation and monoamine metabolism in a sow-piglet model.\nAbstract: Maternal nutrition plays a major role in neurodevelopment. This study hypothesized that maternal egg yolk supplementation will influence offspring choline concentrations, and these changes will be associated with resting-state network (RSN) activation and monoamine neurochemistry at weaning. Sows were fed a control (CON; n = 6) or an egg yolk-supplemented diet (EGG; n = 5) from gestation day 70 to weaning at postnatal day 21, and piglet liver and plasma were collected (CON, n = 24; EGG, n = 20) for choline and metabolite quantification at weaning. Maternal egg yolk supplementation increased liver choline and methionine concentrations in piglets (p < .05). Given our previous findings that egg yolk supplementation elevated executive control and cerebellar functional activation, the associations between metabolites and RSNs were examined. Liver choline was correlated with executive (r = 0.4584) and auditory network activation (r = -0.4751), while plasma choline was correlated with visual network activation (r = 0.5295) (p < .05). As we previously reported that maternal egg yolk supplementation altered piglet monoamine homeostasis, its links to choline and metabolite concentrations were assessed. Liver choline was associated with anterior hippocampal norepinephrine (r = 0.3275) and cerebellar serotonin metabolism (r = 0.3043) and liver TMAO was associated with anterior hippocampal norepinephrine (r = 0.3896), while plasma choline was linked to caudate serotonin (r = 0.3902) and dopamine (r = -0.3763) metabolism (p < .05). Overall, maternal egg yolk supplementation altered offspring choline and metabolite status, which was associated with RSNs and monoamines. These findings broaden our understanding of how one-carbon metabolite status may relate to neurochemical and functional brain outcomes in offspring.\n\nID: 42267298\nTitle: Maternal obesity and inadequate gestational weight gain disrupts placental dopaminergic signaling: impact on infant neurodevelopment.\nAbstract: The maternal-fetal axis plays a critical role in human development. Obesity during pregnancy may be associated with alterations in this axis, particularly the placental dopaminergic signaling, potentially affecting infant neurodevelopment. Participants (n=35) from the OBESO cohort (Mexico City) were classified by pregestational BMI as normal weight (n=20) or obese (n=15). Clinical and anthropometric variables of the mother-infant dyads were recorded. Neurodevelopment was evaluated in one-month-old infants using the Bayley-III Scales and classified as normal or altered (score ≤7 in any domain). Placental dopamine (DA) concentrations were quantified by ELISA and correlated with neurodevelopmental status. A subset of samples was analyzed by Western blot to explore the expression of key dopaminergic components: tyrosine hydroxylase (TH), catechol-O-methyltransferase (COMT), vesicular monoamine transporter 2 (VMAT2), organic cation transporter 3 (OCT3), dopamine transporter (DAT), and dopamine receptor D2 (DRD2). Reduced placental DA concentrations, together with altered expression of key dopaminergic elements characterized by increased COMT and DAT, and decreased VMAT2, were observed in association with maternal obesity, inadequate gestational weight gain, and altered infant neurodevelopment. This study provides exploratory evidence that maternal obesity and inadequate GWG may be associated with early alterations in the intrauterine metabolic and neuroendocrine environment, including changes in the placental dopaminergic system. Differences in the expression of COMT, DAT, and VMAT2, together with lower placental DA concentrations, which may be linked to early neurodevelopmental variability in infants. Overall, the results suggest a potential relationship between maternal metabolic status and placental neuroendocrine pathways, warranting further investigation in larger and longitudinal studies.\n\nID: 42214261\nTitle: Nano-selenium mitigates lead nanoparticle-induced hеpatonеural toxicity and growth performance in quails: Oxidative stress, neurotransmitter and anti-inflammatory response modulation.\nAbstract: Lead nanoparticles pose a significant threat to avian health, disrupting growth, inducing oxidative stress, and impairing neurological function. This study investigated the protective mechanisms of nano-selenium (Nano-Se) against lead oxide nanoparticles (PbNPs)-induced toxicity in Japanese quails (Coturnix coturnix japonica) using a controlled 28-day experimental design. A total of 360 two-week-old quails were randomly assigned to six treatment groups: (1) control (basal diet), (2) Nano-Se (0.2 mg/kg diet), (3) PbNPs-0.25 (0.25 µg/ml in drinking water), (4) PbNPs-0.50 (0.50 µg/ml), (5) Nano-Se + PbNPs-0.25, and (6) Nano-Se + PbNPs-0.50. Histopathological examination revealed dose-dependent hepatocellular necrosis (60-70% of hepatocytes in the high-dose group), vacuolar degeneration, sinusoidal congestion, and widespread neuronal degeneration with prominent satellitosis and neuronophagia. Immunohistochemical analysis confirmed TNF-α-driven neuroinflammation, with intense immunoreactivity in 50-55% of cortical neurons and 65-70% of hepatocytes in PbNPs-exposed groups (3.5-fold increase over controls). These structural lesions were accompanied by a dose-dependent redox crisis, depleting hepatic and neural glutathione S-transferase (GST) activity by 40-50% and elevating lipid peroxidation (MDA 2.5-fold), which correlated with neurotransmitter disruption (serotonin 35%, noradrenaline 45%, acetylcholinesterase 60% reduction) and hepatocyte damage (ALT/AST 3-fold elevation). Remarkably, Nano-Se co-administration attenuated toxicity via three synergistic mechanisms: Nrf2-mediated GST restoration, monoamine oxidase inhibition preserving neurotransmitter balance, and NF-κB suppression reducing Kupffer cell infiltration by 65%, with histopathological protection reducing necrosis incidence by 40-50% and suppressing neuroinflammatory TNF-α expression by 70-90%. Our findings demonstrate Nano-Se's multi-target efficacy against PbNPs toxicity mediated through selenoprotein-dependent and independent mechanisms, highlighting its potential as a nano-antidote for environmental heavy metal exposure.\n\nID: 42128191\nTitle: Phenethylamines in pre-workout supplements alter arterial pressure, heart rate, and body temperature in rats.\nAbstract: Phenethylamine (PEA) and its analogues are frequently present in pre-workout and weight loss food supplements and share structural similarity with amphetamine and the endogenous catecholamines (nor)adrenaline and dopamine, suggesting potential sympathomimetic activity. Multiple adverse cardiovascular events have been associated with the use of food supplements containing these ingredients, while knowledge of the underlying pharmacology and toxicology of such food supplements and their ingredients remains limited. Therefore, the aim of the current study was to investigate the acute cardiovascular effects of a selection of PEAs in conscious rats. Heart rate (HR), arterial pressure (AP) and body temperature were continuously, and wirelessly, monitored using pressure telemetry in Wistar-Kyoto rats that were intravenously exposed to cumulative doses of PEA and seven commonly used analogues: BMPEA, halostachine, higenamine, isopropyloctopamine, p-octopamine, p-synephrine and p-tyramine. All PEAs, except PEA itself and BMPEA, significantly altered AP with maximal absolute increases between 65 and 103 mmHg. Maximal absolute increases in HR induced by higenamine and isopropyloctopamine were found to be 110 and 123 beats per minute, respectively. The PEA analogues BMPEA, p-octopamine, halostachine and p-synephrine, instantly lead to reduced body temperatures, ranging from minus 0.5 to minus 1.5 °C. This study demonstrates that several PEAs, exert pronounced and rapid effects on AP, HR and body temperature in rats. The magnitudes of these effects were similar to or even higher than the cardiovascular changes induced by adrenaline, suggesting that combining these substances with physical exercise may amplify sympathetic load and pose a serious health risk, particularly for individuals with underlying cardiovascular vulnerabilities.\n\nID: 42073336\nTitle: A Fluorescent Composite of Carbon-Dot-Embedded Covalent Organic Frameworks for Highly Sensitive and Rapid Detection of Biogenic Amines in Large Yellow Croaker.\nAbstract: The excessive accumulation of biogenic amines (BAs) in aquatic products poses serious health risks, necessitating the development of rapid and sensitive detection methods. This study reports the synthesis of a novel fluorescent nanocomposite, carbon-dot-embedded covalent organic frameworks (CDs@COFs). Comprehensive characterization (TEM, XPS, FTIR, UV-Vis, and fluorescence spectroscopy) confirmed the successful fabrication of the nanocomposites, which exhibited excellent thermal and optical stability. A significantly enhanced quantum yield of 36.22% (compared with 12.92% for pure carbon dots) was obtained. As a fluorescent probe, the composite enabled the detection of nine BAs based on a fluorescence quenching mechanism. The proposed method demonstrated good linearity (1~100 ng/mL) and low detection limits of 0.58~0.98 ng/mL. The method was successfully applied to analyze tyramine in large yellow croaker, showing accurate spike recoveries ranging from 91.93% to 101.43% and excellent reproducibility (RSD < 3%). These results highlight the great potential of the developed method as a powerful tool for the rapid screening of BAs in aquatic products.\n\nID: 42022562\nTitle: Selegiline, a monoamine oxidase-B inhibitor as a modulator of metabolic reprogramming for cancer therapy: a review.\nAbstract: Metabolic reprogramming plays a crucial role in cancer progression, therapeutic resistance, and tumor-microenvironment remodelling. Monoamine oxidase-B (MAO-B), a mitochondrial enzyme involved in oxidative deamination, has recently been identified as a metabolic regulator that influences reactive oxygen species (ROS) production, mitochondrial homeostasis, and redox-dependent signaling in tumors. Selegiline, an MAO-B inhibitor traditionally used in neurological disorders, is now gaining attention for its potential role in modulating tumor metabolism. Elevated MAO-B activity contributes to oxidative stress, genomic instability, immune suppression, and metabolic adaptations that support tumor survival. By inhibiting MAO-B, selegiline reduces ROS generation, alters mitochondrial respiration, regulates glycolytic flux, and disrupts hypoxia-associated pathways, making it a promising modulator of metabolic checkpoints in oncology. Relevant literature was collected from PubMed, Google Scholar, and ScienceDirect using keywords such as Selegiline, MAO-B inhibitor, tumor metabolism, oxidative stress, and drug repurposing in cancer. Relevant studies from the past 5 years, with inclusion criteria focusing on mechanistic, preclinical, and translational evidence related to MAO-B and selegiline-mediated metabolic regulation. Recent findings indicate that selegiline not only modulates cancer cell metabolism but also influences the tumor microenvironment by reducing inflammatory cytokine production, altering macrophage polarization, and enhancing susceptibility to therapeutic stress. Additionally, combination approaches with chemotherapeutics, metabolic inhibitors, and immunotherapies show synergistic potential. This review summarizes current insights into selegiline's role in metabolic reprogramming, highlights existing challenges, and discusses future opportunities for repositioning selegiline as a targeted metabolic modulator in cancer therapy.\n\nID: 42015463\nTitle: Sex Differences in Levodopa-Sparing Effect of Safinamide: Post-hoc Findings from a Multicenter, Longitudinal, Case-Control Study.\nAbstract: Female sex increases the risk of levodopa-induced dyskinesias in Parkinson's disease (PD). While levodopa-sparing effects of monoamine oxidase-B inhibitors (iMAO-B) are established, sex differences in response to safinamide remain unexplored. To evaluate sex differences in longitudinal (9 ± 3 months) changes in levodopa dose and total levodopa-equivalent daily dose (LEDD) with safinamide 100 mg. We included 259 PD patients treated with safinamide 100 mg (cases, n = 130) or never exposed to iMAO-B (controls, n = 129). The primary outcome was the sex × treatment interaction on the change in levodopa daily dose adjusted for body weight. Safinamide 100 mg improved UPDRS-III scores and reduced OFF-time independently of sex. A significant sex × treatment interaction emerged for change in weight-adjusted levodopa dose and total LEDD, with greater reduction in women (p = 0.025 and 0.045, respectively). Safinamide 100 mg provides a larger levodopa-sparing effect in women, supporting sex-specific optimization of dopaminergic therapy in PD management.\n\nID: 41995884\nTitle: Renalase knockdown inhibits proliferation of mouse satellite cells.\nAbstract: BACKGROUND: Skeletal muscle regeneration is mediated by skeletal muscle stem cells, known as satellite cells. Satellite cell proliferation is regulated by various secreted factors, including exercise-induced cytokines. Renalase is a protein that promotes cell proliferation through activation of intracellular signaling pathways in tumor cells. However, the role of renalase in satellite cell proliferation remains unclear. This study aimed to elucidate the role of renalase in satellite cell proliferation. METHODS AND RESULTS: Satellite cells were isolated from the extensor digitorum longus (EDL) muscles of male mice. Renalase expression was suppressed using an adenoviral vector expressing short hairpin RNA (shRNA). Renalase knockdown significantly suppressed cell numbers, particularly reducing the Pax7⁺/MyoD⁺ cell population. In addition, the numbers of Ki67-positive and EdU-positive cells were significantly reduced, and the expression of genes involved in cell-cycle progression was significantly decreased. Furthermore, the phosphorylation levels of ERK1/2 and Akt, key signaling molecules involved in cell proliferation, were significantly reduced following renalase knockdown. CONCLUSION: These results indicate that renalase is essential for satellite cell proliferation and that renalase knockdown inhibits satellite cell proliferation by suppressing the Akt–mTOR and ERK1/2 signaling pathways.\n\nID: 41971338\nTitle: A pilot study on spoilage dynamics in industrially produced Paneer Shahri, a traditional Iranian fresh cheese.\nAbstract: Paneer Shahri is a traditional Iranian fresh cheese with high moisture and near-neutral pH, making it susceptible to microbial spoilage. This study aimed to assess spoilage-related changes in Paneer Shahri during storage. Microbial, physicochemical, textural, and sensory changes in industrially produced, enzyme-coagulated Paneer Shahri were evaluated during cold storage (8 °C) over 34 days. Despite pasteurization, spoilage was primarily driven by non-starter lactic acid bacteria (NSLAB), including Lactococcus lactis, Enterococcus faecalis, and Lacticaseibacillus rhamnosus. These bacteria, all proteolytic and psychrotrophic, were consistently recovered throughout storage and became dominant members of the microbial community. Fermentation of residual lactose by LAB led to a significant decline in pH and an increase in titratable acidity, creating acidic conditions that further supported LAB persistence. Proteolysis contributed to texture softening, as reflected by declining chewiness, gumminess, springiness, and cohesiveness. Biogenic amine production by E. faecalis, particularly tyramine, was observed, posing a potential safety concern during prolonged storage. No Enterobacteriaceae, coagulase-positive staphylococci, or aerobic spore-formers were detected, and lipolysis remained negligible throughout the storage period. Yeasts and molds appeared only in the late stages of storage, and sensory analysis revealed declining smell and overall acceptability, consistent with microbial and biochemical spoilage markers. These findings highlight the metabolic activity and persistence of NSLAB as key drivers of spoilage in the absence of classical pathogens, emphasizing the importance of monitoring LAB activity to extend shelf life in fresh high-moisture cheeses.\n\nID: 41898153\nTitle: Ayahuasca and Its Main Component N,N-Dimethyltryptamine (DMT) for the Treatment of Mental Disorders: Mechanisms of Action, Clinical Studies, and Tools to Explore the Human Mind.\nAbstract: In recent years, psychopharmacology has experienced a significant challenge, highlighting a renewed and strong scientific interest in psychedelics as breakthrough therapies for mental disorders. Psychedelics can influence cognitive and emotional processes, showing solid therapeutic potential, particularly in treatment-resistant psychiatric disorders. Amongst the most promising compounds, ayahuasca and its main psychoactive component, N,N-dimethyltryptamine (DMT), have received considerable attention. Ayahuasca is a psychoactive brew traditionally prepared from the liana Banisteriopsis caapi and the leaves of Psychotria viridis. Its psychoactive properties derive mainly from DMT, while β-carbolines, which act as monoamine oxidase-A (MAO-A) inhibitors, prevent the metabolic degradation of DMT, enhancing its bioavailability and allowing oral administration. In contrast, in monotherapy, DMT or its analog 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) is generally administered via alternative routes, like inhalation, intranasal, or intravenous delivery. DMT is primarily a serotonin (5-HT)2A receptor partial agonist, whereas 5-MeO-DMT has a higher affinity for the 5-HT1A receptor compared to 5-HT2A, though other receptor targets are engaged, fostering neuroplasticity and a reorganization of brain networks involved in perception, cognition, and mood regulation. Despite limited clinical trials, current evidence offers an optimistic outlook on DMT and 5-MeO-DMT efficacy for treatment-resistant depression (TRD) and major depressive disorder (MDD), whereas evidence for other mental disorders studies is still preliminary. There are four phase II studies with 5-MeO-DMT and one with DMT for TRD, while there are two phase II studies with DMT fumarate for MDD. Beyond their therapeutic potential, psychedelics also represent powerful tools for exploring the human mind, offering valuable insights into brain function and mental health.\n\nID: 41876037\nTitle: Behavioral deficits, organ weight changes, and altered gut microbiota in single-housed middle-aged mice.\nAbstract: In this study, we uncovered novel and intriguing effects of aging on mouse behavior, brain neurotransmitter levels, and gut microbiota, with a particular focus on the transition from young adulthood to middle age. Using C57BL/6 J male mice of different ages (young adults at 12 weeks, middle-aged at 30 weeks, and older middle-aged mice at 45 weeks), we observed notable changes. Middle- and older middle-aged mice exhibited reduced spontaneous activity and shorter central stay times in the open field test compared to young adult mice. Nesting behavior was also delayed in older middle-aged mice. In the novel object recognition test, long-term memory was impaired in middle-aged and older middle-aged mice. However, the concentrations of brain neurotransmitters (such as γ-aminobutyric acid and serotonin) and their precursor amino acids in the prefrontal cortex did not vary significantly with age. Analysis of the cecal microbiota revealed age-related changes in bacterial composition. Specifically, Deferribacterota was significantly more abundant in the middle-aged mice than in the young adult mice, and Pseudomonadota was more abundant in older middle-aged mice than in young adult mice. In conclusion, our study provides an integrative descriptive dataset highlighting age-related differences in behavior and gut microbiota among adult mice, contributing to a better characterization of normal aging processes.\n\nID: 41796714\nTitle: In vitro inhibition of monoamine transport by amphetamine-like pre-workout supplement ingredients.\nAbstract: Phenethylamine (PEA) and alkylamine (AA) analogues are a prominent group of pre-workout food supplement ingredients. They are structurally related to the stimulant amphetamine and to the endogenous catecholamines noradrenaline and dopamine, implying potential cardiovascular and psychological effects. This study systematically investigated the inhibitory potential of 12 PEAs and 4 AAs identified in pre-workout supplements on the human dopamine transporter (hDAT), human noradrenaline transporter (hNET) and human serotonin transporter (hSERT) that are stably overexpressed in HEK 293 cells. All PEAs and AAs tested, except DMAE, inhibited substrate uptake by one or more monoamine transporters. Overall, the substances displayed the highest potency and efficacy at hNET, followed by hDAT and with considerably weaker effects on hSERT. At hNET, potency values (IC50) ranged from 0.5 µM to 123 µM, with maximal inhibition (Emax) ranging from -59.2% to -120%. Inhibition of substrate uptake by hDAT occurred with IC50 values between 4.0 and 95.8 µM and Emax values between -66.8% and -135%. For hSERT 50% inhibition was observed at concentrations ranging from 2.6 µM to 131 µM, with maximal effect between 85.3% and -64.8%. These findings indicate a potential for sympathetic activation and behavioral rewarding and reinforcing effects. Notably, the in vitro potency and efficacy of several PEAs and AAs were comparable to those of the well-known illicit stimulants amphetamine and cocaine. Together, these findings highlight the urgent need to further characterize pharmacokinetic and pharmacodynamic properties of these pre-workout supplement ingredients to support robust risk assessment and informed regulatory decision-making regarding the safety of pre-workout supplement ingredients.\n\nID: 41654159\nTitle: Protective effect of Nootkatone against hippocampal injury in diabetes mellitus with depression via PI3K/AKT pathway: Network pharmacology, molecular docking and experimental validation.\nAbstract: The increasing prevalence of diabetes mellitus with depression (DD) has emerged as a significant global public health concern. Nootkatone (NKT), as a natural sesquiterpenoid compound, exhibits anti-inflammatory, anti-diabetic, and neuroprotective effects. This study aimed to investigate the underlying mechanisms of NKT in treating DD through network pharmacology, molecular docking, and experimental validation. Network pharmacology was utilized to screen the potential targets and mechanisms related to the effects of NKT on DD. Molecular docking was conducted to confirm the interactions between NKT and core targets. The DD model was established through a high-fat diet in conjunction with streptozotocin (STZ) administration and chronic unpredictable mild stress (CUMS). The therapeutic effects of NKT on DD were assessed by indices of glucose metabolism, behavioral tests, H&E staining, enzyme-linked immunosorbent assay (ELISA) and Western blot. Based on network pharmacology and molecular docking analyses, this study proposes the potential mechanisms of NKT on DD, with AKT1 identified as a key target. In vivo experiments demonstrated that NKT improved body weight and glucose metabolism, and alleviated depression-like behaviors in DD mice (P < 0.05). In addition, NKT attenuated neuronal injury and increased monoamine neurotransmitters in the hippocampus (P < 0.05). NKT also decreased inflammatory response induced by STZ-CUMS and upregulated proteins associated with PI3K/AKT pathway (P < 0.05). NKT alleviated depression-like behaviors, attenuated hippocampal injury, and increased monoamine neurotransmitters in DD mice. The protective effect of NKT on DD might be associated with the activation of the PI3K/AKT pathway.\n\nID: 41628748\nTitle: Effects of aerobic exercise on depression-like behaviors and hippocampal transcriptomics in CSDS-induced adolescent mice.\nAbstract: Adolescence is a critical period of vulnerability to depression, yet most evidence for the antidepressant effects of exercise derives from adult models. This study aims to investigate the effects of aerobic exercise and identify its associated molecular changes in the adolescent depression mouse model. A chronic social defeat stress (CSDS) model was established in adolescent male C57BL/6J mice to induce depression-like behaviors. Thirty-six mice were randomly assigned to three groups: control (CG), model (MG), and model plus exercise (ME). MG and ME mice were subjected to CSDS for two weeks (days 7-20), while ME mice additionally received three weeks of aerobic treadmill training covering the whole CSDS period (days 0-20). Behavioral tests were conducted on days 21-26, followed by the collection of serum and hippocampal tissues for molecular, histological, and transcriptomic analyses. CSDS induced significant depression-like behaviors in adolescent male mice, including social avoidance, anhedonia, and behavioral despair, all of which were effectively alleviated by aerobic exercise. Aerobic exercise appeared to mitigate CSDS-induced neural damage and maintain hippocampal tissue integrity. Moreover, aerobic exercise increased serum levels of serotonin. Transcriptomic analysis identified 587 differentially expressed genes (DEGs). Among these genes, 59 overlapping DEGs were regulated by both CSDS and exercise, and were enriched in carbohydrate metabolism and cholinergic signaling pathways. Aerobic exercise alleviates depression-like behaviors in adolescent male mice, possibly by modulating hippocampal gene expression - especially in cholinergic and carbohydrate metabolism pathways - which provides potential clues to how exercise could influence peripheral monoamine levels and hippocampal structural integrity. These putative mechanisms require further investigation.\n\nID: 41559934\nTitle: Renalase deficiency suppresses hepatic triglyceride accumulation in the progression to MASLD/MASH by GAN diet in male mice.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a growing public health concern characterized by hepatic triglyceride (TG) accumulation, inflammation, and fibrosis. Renalase is known for its role in blood pressure regulation and catecholamine metabolism, but recent evidence suggests broader cytokine-like functions. Moreover, its involvement in MASLD remains unclear. In this study, we examined the effects of renalase deficiency on hepatic lipid metabolism in a Gubra Amylin NASH (GAN) diet-induced MASLD model using renalase knockout (KO) mice. Our results show that renalase KO mice exhibited reduced hepatic TG levels, accompanied by decreased gene and protein expression of Srebf1 involved in lipid synthesis, and lower gene expressions of antioxidant and fibrosis markers in KO-GAN compared with wild type (WT)-GAN. Additionally, in vitro experiments using AML12 cells with renalase knockdown confirmed reduced intracellular TG accumulation and lipid synthesis gene expression. Notably, the phosphorylation of Akt was significantly reduced in the liver of renalase-KO mice, indicating that Akt signaling plays a critical role in the observed decrease in hepatic TG levels. These findings suggest that renalase regulates hepatic lipid metabolism through the Akt-Srebf1 pathway, and its deficiency attenuates TG accumulation, suggesting that renalase may modulate early hepatic lipid deposition that progresses toward MASLD.\n\nID: 41494586\nTitle: Microorganisms and Physicochemical Factors Controlling Biogenic Amines During Cheese Ripening: A Systematic Review.\nAbstract: Biogenic amines are nitrogenous compounds formed by amino acid decarboxylation, and their excessive accumulation in cheese may cause adverse health effects. This systematic review aimed to evaluate the effectiveness of probiotic strains and physicochemical factors in reducing biogenic amine levels during cheese ripening. Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, a comprehensive literature search was conducted in PubMed, Scopus, Web of Science, ScienceDirect, and Google Scholar for studies published between 2010 and 2024. Fourteen studies met the inclusion criteria. Among the identified biogenic amines, tyramine and histamine were most frequently reported at high concentrations. The combination of Lactobacillus acidophilus and Lactiplantibacillus plantarum demonstrated the highest efficacy, achieving up to 80% reduction in total biogenic amine levels. Optimal physicochemical conditions, including maintaining a pH range of 5.0-5.4, a ripening temperature around 15 °C, and a maturation period of 3-4 months, enhanced the efficiency of probiotic interventions. Environmental factors such as salt, moisture, fat content, and packaging methods significantly influenced biogenic amine accumulation. Integrating selected probiotics with controlled ripening parameters can minimize biogenic amine levels and improve cheese safety and quality. However, due to heterogeneity in probiotic strains, cheese types, and analytical techniques among the included studies, further standardized and large-scale investigations are required to better understand the mechanisms and optimize strategies for biogenic amine reduction in cheese production.\n\nID: 41492376\nTitle: Milk fat globule membrane ameliorates depressive-like behaviors in chronic unpredictable mild stress rats by modulating the microbiota-gut-brain axis.\nAbstract: Depression is one of the common psychiatric disorders, and it has been reported that the imbalance in the microbiota-gut-brain (MGB) axis contributes to the pathogenesis of depression. Milk fat globule membrane (MFGM) can impact the gut-brain axis by regulating the intestinal flora and metabolite production. The aim of this study was to investigate whether MFGM could ameliorate depressive-like behaviors induced by chronic unpredictable mild stress (CUMS) and further elucidate the potential mechanism through a fecal microbiota transplantation (FMT) experiment. Male Sprague-Dawley rats were provided with an MFGM diet for 5 weeks after the induction with CUMS. Depressive-like behaviors were assessed, and the levels of neurotransmitters, neuroendocrine hormones, microbiota, short-chain fatty acids (SCFAs), and tight junction proteins, including occludin and zonula occludens-1 (ZO-1), were measured. It was revealed that MFGM could alleviate the depressive-like behaviors in CUMS rats. MFGM up-regulated the expression of occludin and ZO-1 and ameliorated intestine pathological changes in CUMS rats. Moreover, MFGM increased the levels of 5-hydroxytryptamine (5-HT), dopamine (DA), and norepinephrine and decreased the levels of neuroendocrine hormones in CUMS rats. Furthermore, it was confirmed that the concentrations of SCFAs, DA, 5-HT, and tight junction proteins significantly increased in the recipient rats that were inoculated with the fecal microbiota from the rats after MFGM treatment. These findings demonstrated that MFGM could alleviate depressive-like behaviors in CUMS rats and was possibly associated with modulation of the gut microbiota and up-regulation of SCFAs and monoamine neurotransmitters.\n\nID: 41488142\nTitle: Placental serotonergic system dysregulation is associated with early impairments in infant neurodevelopment.\nAbstract: Serotonin (5-hydroxytryptamine [5-HT]) plays a fundamental role in fetal neurodevelopment. While 5-HT is synthesized in the fetal brain, the placenta contributes significantly to fetal 5-HT levels during early gestation. However, little is known about the influence of placental serotonergic components on early neurodevelopmental outcomes. In this study, we have evaluated the association between the expression of key components of the placental serotonergic system and neurodevelopmental status in infants of mother-child dyads enrolled in the Origen Bioquímico y Epigenético del Sobrepeso y la Obesidad (OBESO) perinatal cohort at the first month of life. We analyzed 5-HT concentrations in maternal serum, umbilical cord serum, and placental tissue, and investigated the expression of key proteins of the serotonergic system in the placenta. All samples were obtained from full-term healthy pregnancies. 5-HT levels were measured by ELISA, and protein expression in placental tissue was evaluated by Western blot. Neurodevelopment was assessed at 1 month of age using the Bayley Infant Development Scale III (BSID-III). Infants with two or more BSID-III domain scores ≤ 7 were grouped as having altereded neurodevelopment. Placentas from infants with altered neurodevelopment exhibited higher expression of tryptophan hydroxylase types 1 and 2 (TPH1 and TPH2)-the rate-limiting enzymes in 5-HT synthesis-as well as the serotonin transporter (SERT), compared to those from infants with normal neurodevelopment. In contrast, expression of monoamine oxidase-A (MAO-A), the primary degrading enzyme, was significantly lower in the altered group. Interestingly, 5-HT levels and the expression of 5-HT1E and 5-HTR5A receptors were similar between groups. These findings suggest that dysregulation of the placental serotonergic system, independent of total 5-HT levels, could be associated with early neurodevelopmental impairments, highlighting the importance of placental serotonin signaling in fetal brain development.\n\nID: 41465348\nTitle: Expression Alterations and Correlative Analysis of TPH1/hsa-miR-194-5p/NEAT1 and MAOA/hsa-miR-1276/NEAT1 Axes in Pediatric Inflammatory Bowel Disease.\nAbstract: Pediatric inflammatory bowel disease (pIBD), comprising ulcerative colitis (UC) and Crohn's disease (CD), involves complex mechanisms that include non-coding RNAs (ncRNAs), such as microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), alongside enzymes regulating serotonin metabolism. Tryptophan hydroxylase 1 (TPH1) and monoamine oxidase A (MAOA) play critical roles in serotonin turnover and may contribute to intestinal inflammation. We investigated the expression of TPH1, MAOA, hsa-miR-194-5p, hsa-miR-1276, and the lncRNA Nuclear Enriched Abundant Transcript 1 (NEAT1) in intestinal tissue biopsies and peripheral blood from pIBD patients and controls. TPH1 was significantly elevated in the inflamed transverse colon (p = 0.034), whereas MAOA was reduced in the ileum (p = 0.041) and descending colon (p = 0.001), with further decreases in inflamed ileum (p < 0.001), ascending (p = 0.008), and descending colon (p = 0.001). Subgroup analysis revealed decreased MAOA in the ascending colon of UC patients (p = 0.011). hsa-miR-194-5p was upregulated in the transverse colon (p = 0.015), inflamed transverse (p = 0.013) and descending colon (p = 0.015), and in blood of UC patients (p = 0.01). NEAT1 expression increased in the ascending colon (p = 0.042) but decreased in the ileum (p = 0.006). Correlation analysis showed strong positive associations between TPH1 and NEAT1 in the ileum (r = 0.945, p < 0.01) and transverse colon (r = 0.609, p < 0.01). These results highlight region-specific dysregulation of serotonin-related genes and ncRNAs in pIBD, with the TPH1/miR-194-5p/NEAT1 axis potentially contributing to disease pathophysiology and warranting further mechanistic investigation.\n\nID: 41462983\nTitle: New Insights into Complex PTSD Treatment: Focus on TAAR1 Agonists.\nAbstract: Background/Objectives: The therapeutic potential of selective trace amine-associated receptor 1 (TAAR1) agonists has been established in multiple animal models of depression and anxiety. PTSD is a debilitating psychiatric disorder frequently characterized by anxiety and often comorbid with major depressive disorder. Complex PTSD represents an even more severe clinical presentation, emerging from prolonged or repeated exposure to traumatic events. Recent studies indicate that TAAR1 agonists can attenuate anxiety-like behaviors in experimental models of PTSD; however, the molecular mechanisms underlying this effect remain poorly understood. In this study, we evaluated whether TAAR1 agonism modulates PTSD-related neurochemical and molecular changes within the hippocampus and striatum. Methods: Post-traumatic stress was modeled using predator stress, a validated experimental paradigm relevant to complex PTSD. Treatment consisted of intraperitoneal administration of the TAAR1 agonist LK00764. Monoamine neurotransmitters and their metabolites were quantified, and the expression of genes implicated in noradrenergic, dopaminergic, and serotonergic signaling pathways was assessed. In addition, gene network reconstruction was performed using artificial intelligence to identify TAAR1-dependent regulatory interactions. Results: Treatment with a TAAR1 agonist fully prevented behavioral abnormalities in the experimental model of complex PTSD. Neurochemical analyses revealed decreased 5-HT levels in the hippocampus and reduced dopamine and metabolite concentrations in the striatum following TAAR1 agonism. Moreover, TAAR1 activation was associated with increased expression of the neurotrophic factor BDNF in the striatum. Gene network reconstruction identified a distinct molecular hub within the PTSD network, comprising TAAR1-coexpressed genes, their encoded proteins, and interconnected signaling pathways, suggesting a tightly regulated feedback loop. Conclusions: These findings provide novel evidence that TAAR1 agonists exert protective effects against complex PTSD-related behavioral and neurochemical abnormalities. The reconstructed TAAR1-centered gene network offers mechanistic insight into receptor-dependent regulation of monoaminergic signaling and neuroplasticity, supporting further exploration of TAAR1 agonists as promising therapeutic candidates for PTSD.\n\nID: 41421311\nTitle: Orange corn diet modulates Pekin duck cecal neurochemistry under normal and heat stress conditions.\nAbstract: Heat stress (HS) drives changes in poultry gut health that negatively affect performance, behavior, foodborne pathogen carriage, among other factors. Little attention, however, has been directed towards the impact of HS on the duck intestinal tract. Intestinal concentrations of monoamine neurochemicals, which have been shown to be stress-responsive in several poultry species, play a variety of roles in mediating the effects of stress both locally in the gut and in overall physiology. Yet, the concentrations of neurochemicals and accompanying metabolic pathways in the duck intestine remain understudied. As an orange corn (OC) diet was previously shown in poultry to benefit welfare and performance, the present study sought to determine the impact of an OC versus a yellow corn (YC) diet on duck intestinal monoamine neurochemistry under thermoneutral and heat stress conditions. Male and female Pekin ducks were randomly assigned to a YC or OC diet, with each diet fed for 3 wks immediately before HS, and then continuing being fed during the 3 wks of cyclic HS exposure (35°C for 10h/d). Cecal tissue (CT) and luminal content (CC) were collected before the start of HS and then on the final day of the 3 wks of HS. Sex and feed type affected (p < 0.05) catecholamine and serotonin concentrations in ducks under thermoneutral and HS conditions. CT protein expression of monoamine oxidase-A and catechol-o-methyltransferase showed sex- and feed type-dependent changes (p < 0.05) only in ducks that underwent HS. DOPA-decarboxylase was affected (p < 0.05) under HS but not during constitutive conditions. The present study establishes that the duck intestinal tract is an abundant source of monoamine neurochemicals, and that key proteins involved in neurochemical metabolism are present in the duck ceca. These findings warrant the study of feed components as a tailorable strategy to potentially control stress at the gut-level. As enteric neurochemicals play critical roles in inflammation, foodborne pathogen colonization, and other production-relevant aspects in poultry, our findings highlight the importance of intestinal neurophysiology in the duck.\n\nID: 41370292\nTitle: Caste- and age-specific venom composition of biogenic amines and the influence of diet in honey bees.\nAbstract: The chemical composition of the venom in social Hymenoptera differs between castes and ages. Biogenic amines are contained in the venom of honey bees and may be physiologically effective to vertebrate predators and insects. This study quantified the concentrations of biogenic amines in venom and compared them between different castes and ages of honey bees. The concentrations of dopamine and N-acetyldopamine in venom were significantly higher in virgin queens than workers of the same age. The concentrations of dopamine, norepinephrine, tyramine and serotonin increased with age in virgin queens and workers. There was a significant positive correlation between venom dopamine concentrations and ovarian development in queenless workers, suggesting that the concentration of dopamine in the venom transformed from normal workers to reproductive females as that in virgin queens. We also tested the possibility of dietary effects on the concentration of dopamine in venom. Workers fed tyrosine or royal jelly showed significantly higher concentrations of dopamine precursors, tyrosine, 3,4-dihydroxyphenylalanine (DOPA) and dopamine in the hemolymph, as well as higher concentrations of dopamine in venom than in controlled workers. These results suggest that compositions of biogenic amines in venom are influenced by nutrition and change based on their social roles in honey bee society.\n\nID: 41369149\nTitle: Bioavailability and Metabolism of N-Trans Caffeoyltyramine and N-Trans Feruloyltyramine - A Narrative Review.\nAbstract: Insights into the bioavailability of hemp derived phenolic amides N-trans caffeoyltyramine (NCT) and N-trans feruloyltyramine (NFT) remained limited to experimental data from preclinical in vitro and animal systems. However, the bioavailability of similar phenolics and phenolic amides from other sources has been experimentally determined. This concise review summarizes the current state of knowledge for phenolic amides with the goal of providing experimental guidance on the assessment of NCT and NFT from hemp ingredients in humans. Evidence from phenolic and avenanthramide (similar phenolic amides from oats) suggest that overall absorption of free phenolic amides would be limited in humans to <2% of native forms. Metabolites derived by both host (conjugated Phase II metabolites) and microbial fermentation products would likely represent the main compounds in circulation derived from NCT or NFT intake. This would be extensively influenced by the matrix provided including hemp-based ingredients with large portions of physically and chemically bound NCT and NFT forms that are not absorbable. Experimental designs to determine NCT and NFT response in humans would need to consider longer exposure and collection periods to adequately capture 24 and 48h urine and blood samples likely to have key NCT and NFT derived microbial and host metabolites present. Considering adaptation of the microbiota to these compounds it is likely that a robust design would also include a dimension of long-term exposure to enable detection of target metabolites derived from hemp NCT and NFT.\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’s complementary-but-disjoint (A-B-C) model.

Hence, this study investigated the tyrosine metabolism of Enterobacteriaceae and Enterococcaceae strains isolated from patients post-RYGB and explored the causal effects of tyramine on the CRC risk and tumorigenesis using both human colonic cancer cell line (HCT 116) and wild-type and ApcMin/+ mice. We isolated 31 bacterial isolates belonging to Enterobacteriaceae and Enterococcaceae families from the feces of patients with RYGB surgery. By culturing the isolates in tyrosine-supplemented medium, we found that Citrobacter produced phenol as a main product of tyrosine, whereas Enterobacter and Klebsiella produced 4-hydroxyphenylacetate, Escherichia produced 4-hydroxyphenyllactate and 4-hydroxyphenylpyruvate, and Enterococcus and two Klebsiella isolates produced tyramine. These observations suggested the gut bacterial contribution to increased fecal concentrations of tyramine post-RYGB. We subsequently evaluated the impact of tyramine on CRC risk and development. Tyramine induced necrosis and promoted cell proliferation and DNA damage of HCT 116 cells. Daily oral administration of tyramine for 49 days to wild-type mice resulted in visible adenomas in 5 out of 12 mice, accompanied by significantly enhanced DNA damage (γH2AX +) and an increased trend of cell proliferation (Ki67 +) in the ileum, along with an upregulated expression of the cell division cycle gene (Cdc34b) in the colon. To evaluate the impact of tyramine on intestinal tumor growth, we treated ApcMin/+ mice with the same doses of tyramine and duration. These mice showed larger colonic tumor size and increased intestinal cell proliferation and inflammation (e.g., increased mRNA expression of IL-17A and higher number of Ly6G + neutrophils) compared to water-treated ApcMin/+ control mice. Our results collectively suggested that RYGB-associated fecal bacteria could contribute to tyramine production and tyramine increased CRC risk by increasing DNA damage, cell proliferation, and pro-inflammatory responses of the gut. Monitoring and modulating tyramine concentrations in high-risk individuals could aid CRC prognosis and management.

Hemp hull powder is a rich source of two bioactive compounds, N-trans-caffeoyl tyramine (NCT) and N-trans-feruloyl tyramine (NFT), with potential gut health benefits. Methods: The study participants included 23 male and female cyclists. A three-arm randomized, placebo-controlled, double-blind, crossover design was used with two 2-week supplementation periods and 2-week washout periods. Supplement bars provided 20, 5, or 0 g/d of hemp hull powder. Participants engaged in an intensive 2.25 h cycling bout at the end of each of the three supplementation periods. Five blood samples were collected before and after supplementation (overnight fasted state), and at 0 h-, 1.5 h-, and 3 h-post-exercise. Five-hour urine samples were collected pre-supplementation and post-2.25 h cycling after ingesting a sugar solution containing 5 g of lactulose, 100 mg of 13C mannitol, and 1.9 g of mannitol in 450 mL of water. An increase in the post-exercise lactulose/13C mannitol ratio (L:13CM) was used as the primary indicator of altered gut permeability. Other outcome measures included muscle damage biomarkers (serum creatine kinase, myoglobin), serum cortisol, complete blood cell counts, and shifts in plasma metabolites using untargeted metabolomics. Results: No trial differences were found for L:13CM, cortisol, blood cell counts, and muscle damage biomarkers. Orthogonal partial least-squares discriminant analysis (OPLSDA) showed distinct trial differences when comparing high- and low-dose hemp fiber compared to placebo supplementation (R2Y = 0.987 and 0.995, respectively). Variable Importance in Projection (VIP) scores identified several relevant metabolites, including 3-hydroxy-4-methoxybenzoic acid (VIP = 1.9), serotonin (VIP = 1.5), 5-hydroxytryptophan (VIP = 1.4), and 4-methoxycinnamic acid (VIP = 1.4). Mummichog analysis showed significant effects of hemp fiber intake on multiple metabolic pathways, including alpha-linolenic acid, porphyrin, sphingolipid, arginine and proline, tryptophan, and primary bile acid metabolism. Conclusions: Hemp fiber intake during a 2-week supplementation period did not have a significant effect on post-exercise gut permeability in cyclists (2.25 h cycling bout) using urine sugar data. On the contrary, untargeted metabolomics showed that the combination of consuming nutrient-rich hemp fiber bars and exercising for 135 min increased levels of beneficial metabolites, including those derived from the gut in healthy cyclists.\n  --- END ACTUAL ABSTRACT FOR 40284247 ---\n\n\n✅ PASSED (DO NOT CHANGE THESE):\n- \"E. faecium B6 and its metabolite tyramine significantly disrupted the intestinal barrier and increased intestinal permeability in mice.\" (Source: 41299593)\n- \"This favorable microbial shift was accompanied by a reconfiguration of the intestinal metabolome, characterized by elevated production of beneficial short-chain fatty acids (SCFAs) and decreased levels of pro-inflammatory metabolites such as tyramine.\" (Source: 42083198)\n- \"Enterococcus-derived tyramine suppresses ISC proliferation, thereby impairing epithelial regeneration and exacerbating DSS-induced colitis through ADRA2A.\" (Source: 38788722)\n- \"The patient-derived Enterococcus faecium B6 (E. faecium B6) significantly contributed to NAFLD symptoms in mice.

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]\nDietary habits beneficial toward reducing excess/harmful tyramine to improve liver and gut health.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific literature indicates that tyramine, a biogenic amine produced by gut microbiota (e.g., *Enterococcus*), is associated with metabolic dysfunction-associated steatotic liver disease (MASLD), intestinal barrier damage, and colitis exacerbation. Beneficial dietary strategies to modulate tyramine levels include specific prebiotic supplementation, protein restriction or modulation, and the use of probiotic strains known to minimize amine production.\n\n### [INTRODUCTION & JUSTIFICATION]\nTyramine is a bioactive trace amine that, while potentially beneficial in specific neurological contexts, exhibits clear pathogenic properties when produced in excess by gut commensals like *Enterococcus*. The provided evidence confirms that \"E. faecium B6 and its metabolite tyramine significantly disrupted the intestinal barrier and increased intestinal permeability in mice.\" Elevated tyramine is linked to \"lipid accumulation, inflammation, and fibrosis in the liver,\" as validated in MASLD models. Dietary intervention acts as a primary modulator of this pathway. For instance, the consumption of yeast-derived beta-glucans has been shown to induce a \"reduction in tyramine, histamine, and cadaverine on day 60.\" Furthermore, metabolic profiling suggests that protein composition is a critical lever, as \"the contents of histamine, spermidine, spermine and tyramine of muscle were decreased with the VLP diet compared to the NP diet.\" Beyond protein restriction, fermentation control is vital; using specific starter cultures like *Lactiplantibacillus plantarum* results in products where \"histamine and tyramine were undetectable.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Tyramine is not inherently \"bad\"; it acts as a ligand for TAAR1, and in specific postprandial contexts, it can even exert anorexigenic (appetite-suppressing) effects via the hypothalamus.\n*   The \"harmfulness\" of tyramine is context-dependent, relying heavily on the integrity of the intestinal barrier and the presence of specific receptors like ADRA2A in stem cells.\n*   Marination of foods (like fish) significantly increases tyramine concentrations, suggesting that kitchen preparation methods are as important as the raw ingredients themselves.\n*   Enterococcaceae are identified as major drivers of tyramine production post-bariatric surgery, a key risk factor for colorectal cancer.\n*   Sulfonation is a natural detoxification pathway, and gut microbes possess enzymes (ASSTs) that can regulate the concentrations of tyramine sulfate.\n*   Low-protein diets (VLP) can specifically reduce the cecal bioamine load in porcine models, suggesting a broader potential for human metabolic health.\n*   Probiotic supplementation with *Lactobacillus acidophilus* and *Lactiplantibacillus plantarum* is highly efficient, capable of reducing total biogenic amine levels by up to 80%.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Roux-en-Y gastric bypass (RYGB) has been associated with increased long-term CRC risk (HR 1.55 at 10-14 years), whereas sleeve gastrectomy (SG) shows no equivalent elevation, though shorter follow-up (mean 4.5 vs. 8.5 years) precludes definitive conclusions. This review develops a biologically plausible mechanistic framework for these divergent outcomes. RYGB-induced anatomical bypass and accelerated transit are proposed to drive distal substrate overload, with an associated shift of the colonic microbiome toward proteolytic fermentation. The proposed genotoxic luminal environment is characterized by convergent actions of secondary bile acids, tyramine, and hydrogen sulfide, compounded by butyrate depletion.

Dietary intervention with squid-derived CS significantly attenuated characteristic UC symptoms, including body weight loss, colon shortening, and histopathological damage. Mechanistic analyses revealed that squid-derived CS exerted potent anti-inflammatory effects by downregulating key pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) and alleviated oxidative stress by enhancing colonic antioxidant capacity, as evidenced by increased activities of catalase (CAT) and superoxide dismutase (SOD) and reduced myeloperoxidase (MPO) activity. Integrated 16S rRNA gene sequencing and metabolomics analyses demonstrated that squid-derived CS profoundly restructured gut microbial community composition by enriching putative beneficial bacteria (e.g., Bifidobacterium, Clostridium, Blautia) while reducing opportunistic pathogens (e.g., Enterococcus, Sutterellaceae, Clostridia_UCG-014). This favorable microbial shift was accompanied by a reconfiguration of the intestinal metabolome, characterized by elevated production of beneficial short-chain fatty acids (SCFAs) and decreased levels of pro-inflammatory metabolites such as tyramine. Furthermore, squid-derived CS effectively enhanced intestinal barrier integrity by upregulating key tight junction proteins (ZO-1, occludin, claudin-1), thereby preventing bacterial lipopolysaccharide (LPS) translocation and associated liver injury, as indicated by reduced serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Collectively, these findings demonstrate that dietary squid-derived CS protects against UC by modulating gut microbiota composition to enrich beneficial taxa, restoring microbial metabolite homeostasis, reinforcing the intestinal epithelial barrier, and suppressing inflammatory responses and oxidative stress. This study provides the first evidence that squid-derived CS acts as a novel and promising marine prebiotic candidate for gut health promotion, highlighting its potential as a sustainable functional ingredient derived from processing waste for gut-health-promoting foods."},{"quote":"Inoculation significantly enhanced product safety, achieving up to 44.82% reduction in total nitrosamines.

Three strains showing high protease activity (> 90.00 U/mL) and low BA levels (< 40 mg/kg) were isolated from naturally fermented douchi: A1 Bacillus velezensis, A2 B. glycinifermentans, and A3 B. subtilis. A1, with the lowest total biogenic amine (TBA) levels, was selected as the representative strain. The optimal fermentation conditions (8% inoculum, 37°C temperature, 3 days duration) reduced TBA to levels well below the FDA standard (< 1000 mg/kg). Compared to the natural fermentation (NF), it was verified that the TBA of douchi was lowered to 10.51 ± 0.21 mg/kg after optimized fermentation, approximately reduced 10.80-fold. Spermine levels decreased by 43.17-fold, followed by tyramine and phenethylamine. Further, apply them to large-scale cultivation (scaled up by 100-fold) in actual production during colony-enhanced fermentation (CEF). The physicochemical properties and BA levels were monitored to assess the correlation. The findings showed that the douchi of CEF had up to 0.94% amino acid nitrogen (≥ 0.25% EN) and 0.72% total acid (≤ 2.5% EN). The TBA level was only 38.27 ± 0.13 mg/kg, significantly lower than NF (94.94 ± 2.59 mg/kg). This study proposed BA-reducing methods through strain screening and process optimization, particularly achieving large-scale verification from the laboratory to the factory. This approach significantly reduced the TBA levels in bacteria-type douchi, offering a crucial reference for the industrial-scale safe production of fermented soybean products. PRACTICAL APPLICATIONS: This research offers industrial-level guidance for douchi production. By utilizing Bacillus velezensis A1 and optimizing the process, the TBA can be reduced by a factor of 2.5 while maintaining product quality (T/GZSX 014-2018).

Our study aims to investigate associations between central obesity replacement indices, dietary intake of sugar and lipids, and OAB risk using National Health and Nutrition Examination Survey 2005-2016 data. Cross-sectional study. This study analyzed 24,675 adults (4848 OAB cases). Weight, body mass index, and other central obesity replacement indices (waist circumference, weight-adjusted waist index, waist-to-height ratio (WHtR), body roundness index (BRI)) and dietary nutrients intake (carbohydrate, sugars, fat, saturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids (PUFAs), and cholesterol) were assessed. Propensity score matching (1:2) balanced covariates. Multivariable logistic regression and generalized additive models evaluated dose-response relationships. All central obesity indices showed significant positive associations with OAB (p < 0.001), with WHtR and BRI demonstrating the strongest effects (adjusted odds ratio (OR) = 2.04, 95% confidence interval: 1.80-2.30). Nonlinear relationships were observed, particularly for WHtR (degrees of freedom = 3.30-6.16). Dietary analysis revealed that OAB patients had significantly higher consumption of total energy, carbohydrates, and sugars (all p < 0.05), and higher sugar intake increased OAB risk (OR = 1.32, p = 0.0016), while PUFAs were protective (OR = 0.79, p = 0.0159). Central obesity replacement indices, especially WHtR and BRI, strongly predict OAB risk. Dietary modifications, including reducing sugars and increasing PUFAs intake, may complement abdominal fat reduction for OAB prevention. These findings highlight the importance of combined weight management and dietary modifications for OAB prevention in high-risk populations. Can the fats we eat and belly fat affect bladder health? Overactive bladder (OAB) can seriously affect daily life. Using data from over 24,000 U.S. adults, this study found that people with more belly fat were more likely to have OAB, especially when their waist-to-height ratio and body roundness index were high. Diet also mattered—those who ate more sugars had higher OAB risk, while consuming more healthy fats, such as polyunsaturated fatty acids (PUFAs), was linked to lower risk. Managing abdominal fat and improving diet may help prevent or relieve OAB symptoms."},{"quote":"Tyrosine decarboxylases (TyDCs) are pyridoxal 5'-phosphate-dependent enzymes that catalyze the conversion of l-tyrosine into tyramine, a key entry point for Amaryllidaceae alkaloid biosynthesis.","source_id":"42409273","status":"PASS","error":"","abstract_text":"ID: 42409273\nTitle: Molecular cloning and functional characterization of tyrosine decarboxylase genes from galanthamine-producing Narcissus pseudonarcissus 'King Alfred.'.\nAbstract: Tyrosine decarboxylases (TyDCs) are pyridoxal 5'-phosphate-dependent enzymes that catalyze the conversion of l-tyrosine into tyramine, a key entry point for Amaryllidaceae alkaloid biosynthesis. From transcriptome data of Narcissus pseudonarcissus 'King Alfred', two full-length TyDC isoforms, NpTyDC1 and NpTyDC2, were identified. In this study, both genes were cloned, heterologously expressed in Escherichia coli, and purified for functional characterization. Fluorescent protein tagging indicated nucleocytoplasmic localization of both isoforms. Enzymatic assays coupled with HPLC-MS/MS demonstrated that NpTyDC1 exhibits decarboxylase activity with a strong preference for l-tyrosine, producing tyramine as the predominant product. In contrast, NpTYDC2 showed no detectable tyrosine decarboxylase activity under the conditions tested, and no tryptophan decarboxylation despite structural features associated with indole decarboxylases but displayed minor activity toward l-phenylalanine.

Metabolomic profiling of fecal microbial extracellular vesicles (EVs) offers a promising yet underexplored avenue for biomarker discovery when integrated with explainable machine learning (ML) frameworks. This study aimed to identify stool-derived microbial EV metabolite biomarkers that discriminate CRC patients from healthy controls and to develop interpretable ML classifiers for non-invasive CRC detection. Metabolomic profiles of fecal microbial EVs from 76 age- and sex-comparable participants (36 CRC, 40 controls) were obtained using LC/QTOFMS and GC/TOFMS. Three ML classifiers (TPOT, LightGBM, XGBoost) were trained and evaluated through 100-repeat stratified hold-out and nested 5-fold cross-validation, with SHAP and LIME applied for global and local interpretability. Fourteen metabolites were significantly dysregulated between the CRC and control groups (adjusted p < 0.05), with 13 upregulated and one (aminoisobutyric acid) downregulated. Furoic acid exhibited perfect diagnostic discrimination, followed by palmitic acid and tyramine. Nested cross-validation demonstrated robust performance: TPOT achieved AUC = 0.997 ± 0.005, sensitivity = 0.973 ± 0.022, and MCC = 0.957 ± 0.033. Hold-out validation corroborated these findings (AUC = 0.998 ± 0.008). SHAP analysis identified furoic acid, palmitic acid, and tyramine as the dominant predictive features, while aminoisobutyric acid exhibited a distinctive protective pattern. LIME analysis corroborated these findings at the individual prediction level.

H₂O₂, although not a tumor-specific biomarker, is an important reactive oxygen species associated with oxidative stress in cancer-related systems. The proposed sensing platform integrates the high conductivity of rGO, the electrocatalytic activity of Pt NPs, the TSA-derived Fc-Tyr deposition strategy, and the anti-interference properties of POPD. The sensor exhibited two wide linear detection ranges (5.0 µM-570 µM and 570 µM-10.5 mM), a low detection limit of 1.18 µM, and a rapid response time of less than 5 s. In addition, the sensor demonstrated satisfactory selectivity, reproducibility, and stability. Compared to previously reported rGO/Pt-based H₂O₂ sensors, the present platform introduces a TSA-derived Fc-Tyr deposition strategy to facilitate interfacial electron transfer and increase the density of redox-active species. The sensor was successfully applied to monitoring H₂O₂ changes in cultured cancer cells and ex vivo tumor tissue-derived samples under chemically stimulated oxidative conditions.

This study is the first to elucidate relationships between gut health parameters and performance in broilers fed Hermetia illucens (HI) and Tenebrio molitor (TM) meals at 5% or 10% inclusion levels, singly or in a 1:1 combination. A 37-day trial used 420 male Ross 308 chicks randomly allocated to seven treatments: control (C), HI5 (5% HI), HI10 (10% HI), TM5 (5% TM), TM10 (10% TM), MIX5 (5% MIX), and MIX10 (10% MIX).

However, its influence on the police performance of Kunming dogs and the underlying mechanisms remain largely unexplored. This study was the first to apply multi-omics technologies to investigate the dynamic variations in gut microbiota and their metabolic profiles across different ages of Kunming dogs. Furthermore, we systematically examined the associations between these microbial alterations and police performance metrics, providing a theoretical foundation for enhancing the working capabilities of Kunming dogs through targeted modulation of intestinal microecology. The study showed that puppies, young dogs and adult dogs had significantly better police performance than elderly dogs, with young dogs exhibiting the highest scores. Analysis of 16S rRNA sequencing demonstrated that gut microbial diversity and stability were highest during the young dog stage, gradually declining with age. Metagenomic analysis revealed that the abundance of Lactobacillus acidophilus, Lactobacillus johnsonii, Limosilactobacillus reuteri, Ligilactobacillus animalis and Muribaculum gordoncarteri were strongly correlated with police performance. The results of metagenome-assembled genomes (MAGs) indicated that the above species have functional genes involved in GABAergic and glutamatergic synapse pathways.

Sulfotransferases catalyze these reactions by transferring a sulfo group from a donor to an acceptor molecule. Human cytosolic sulfotransferases use only 3'-phosphoadenosine 5'-phosphosulfate (PAPS) as a donor to sulfonate a variety of chemicals. Less understood are microbial aryl-sulfate sulfotransferases (ASSTs), which catalyze sulfo transfer reactions, without utilizing PAPS as a donor. Currently, the identity of physiological sulfo donor substrates remains unknown and sulfo acceptor substrates are underexplored. With this study, we aim to understand the potential contribution of a gut microbial enzyme to sulfonation chemistry by uncovering its substrate preferences. Here, we show that a sulfotransferase (Bacteroides vulgatus ASST) from the prevalent gut microbe B. vulgatus (now Phocaeicola vulgatus) is a versatile catalyst that utilizes a wide range of phenolic molecules as substrates that are commonly encountered by the host.

A total of 290 participants were selected using multi-stage sampling. Quantitative data were collected using structured questionnaires while qualitative data were obtained through 18 key informant interviews and 37 Focus Group Discussions (FGDs) involving pregnant and lactating women, elderly men and women, women of reproductive age and adult men. Data on demographic characteristics were analyzed using SPSS version 31, while qualitative data were analyzed thematically using systematic text condensation. Overall, 88% of participants reported the existence of food taboos in their communities. Pregnancy and lactation were the life stages with the most restrictions (32%) and the least were during menstruation (12%). Commonly tabooed foods during pregnancy included honey, ghee, sheep meat, chili, papaya and whole grains primarily due to beliefs linking them to miscarriage, fetal deformities and labor complications. Liver was universally restricted for children under two years due to perceived speech delay. Men also faced prohibitions such organ meats except liver, animal head, neck and leg meat, considered foods for females and associated with shame, weakness and cowardice. Regional variations were observed with certain taboos being specific to regions, mostly Mudug and Eyl district of Nugaal region.

The literature suggests that the accumulation of tyramine is linked to deleterious effects in the gut-liver axis, including colorectal cancer risk, inflammatory bowel disease (IBD) pathogenesis, and metabolic dysregulation. Specifically, the proposed genotoxic luminal environment is characterized by convergent actions of secondary bile acids, tyramine, and hydrogen sulfide, compounded by butyrate depletion. To mitigate these risks, nutritional interventions focus on modulating the gut microbial composition to minimize tyramine production or enhance its degradation. \n\nBeneficial dietary habits involve replacing specific carbohydrate sources and limiting pro-inflammatory patterns. Research indicates that dietary modifications, including reducing sugars and increasing PUFAs intake, may complement abdominal fat reduction for OAB prevention. Furthermore, the consumption of probiotic strains, such as *Lacticaseibacillus rhamnosus* H7, has shown significant potential in fermentation processes to lower biogenic amine concentrations. Notably, the inoculation significantly enhanced product safety, achieving up to 44.82% reduction in total nitrosamines. Simultaneously, total biogenic amines were reduced by up to 33.17%, particularly putrescine, cadaverine, tyramine, and histamine. Other strategies involve consuming specific prebiotics, as this favorable microbial shift was accompanied by a reconfiguration of the intestinal metabolome, characterized by elevated production of beneficial short-chain fatty acids (SCFAs) and decreased levels of pro-inflammatory metabolites such as tyramine. Therapeutic diets for gastrointestinal health in dogs also suggest that highly digestible diets can result in lower fecal pH and greater fecal concentrations of total short-chain fatty acids and butyrate, serving as potential models for diet-microbiome modulation. Finally, for patients with cirrhosis, nutritional guidance favors balanced patterns, as current recommendations advocate a protein intake of approximately 1.2-1.3 g/kg/day, adjusted for dialysis-related protein losses and inflammatory status. \n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Tyramine oxidation is a specific metabolic function attributed to *Pseudomonas* species within the microbiome.\n*   Fermented foods, often criticized for high amine content, can be optimized using specific starter cultures like *Bacillus velezensis* A1 to drastically reduce biogenic amine levels.\n*   The TAAR1 receptor pathway serves as a sensing mechanism for trace amines like tyramine, where inhibition (e.g., via EPPTB) can mitigate colitis symptoms.\n*   High dietary intake of simple sugars is linked to a shift in microbiome dynamics, reducing the necessity for microbial cooperation and favoring potentially hostile, amine-producing ecological interactions.\n*   The use of iron oxide chitosan nanoparticles (GTPP-IOCHNP) enhances the bioavailability of green tea polyphenols, which modulate hepatic protein expression and inhibit cytochrome P450 enzymes involved in metabolic drug handling.\n*   Dietary patterns following UK-DRV index guidelines, emphasizing fish and fiber, correlate with reduced NAFLD prevalence.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The study examined the prevalence of food taboos, tabooed foods and explored reasons for their existence among different segments of Puntland communities. A community based mixed methods cross-sectional study was conducted between September and December across the nine regions of Puntland state of Somalia. A total of 290 participants were selected using multi-stage sampling. Quantitative data were collected using structured questionnaires while qualitative data were obtained through 18 key informant interviews and 37 Focus Group Discussions (FGDs) involving pregnant and lactating women, elderly men and women, women of reproductive age and adult men. Data on demographic characteristics were analyzed using SPSS version 31, while qualitative data were analyzed thematically using systematic text condensation. Overall, 88% of participants reported the existence of food taboos in their communities. Pregnancy and lactation were the life stages with the most restrictions (32%) and the least were during menstruation (12%). Commonly tabooed foods during pregnancy included honey, ghee, sheep meat, chili, papaya and whole grains primarily due to beliefs linking them to miscarriage, fetal deformities and labor complications. Liver was universally restricted for children under two years due to perceived speech delay. Men also faced prohibitions such organ meats except liver, animal head, neck and leg meat, considered foods for females and associated with shame, weakness and cowardice. Regional variations were observed with certain taboos being specific to regions, mostly Mudug and Eyl district of Nugaal region. Food taboos are common throughout Puntland but they are more rampant in Mudug region and Eyl district of Nugaal region. Some taboos reported during menstruation and illness have some scientific backup and may contribute to better management of these conditions. However, taboos like those reported during pregnancy and lactation may reduce dietary diversity and negatively impact overall nutrition and health outcomes in vulnerable groups.\n\nID: 42418876\nTitle: Deciphering underground decarboxylase activity towards Nε-modified lysine derivatives in enterobacteria.\nAbstract: Thermal food processing generates diverse compounds interacting with the gut microbiota. Despite their abundance, the microbial turnover of diet-borne Nε-modified lysine derivatives remains largely unexplored. We demonstrate that the enterobacterial ornithine decarboxylase SpeC degrades the prevalent advanced glycation end product Nε-carboxymethyllysine (CML) to carboxymethylcadaverine via an underground activity (∼4 molecules/enzyme/min). This promiscuity extends to additional Nε-modified lysine derivatives - namely formylated (FmL), monomethylated (MML) and dimethylated (DML) lysine - yielding previously unknown biogenic amines (mono- and dimethylcadaverine, formylcadaverine). Functionally, SpeC enables Escherichia coli to utilize CML as a sole nitrogen source. In specific strains, this metabolism reinforces pH-stress responses, supporting survival under mild acidic conditions typical for the colon. Furthermore, SpeC orthologs are widespread across human gut genomes, correlating with geography, diet, and disease. Together, these findings suggest a potential diet-microbiome communication axis, linking the intake of modified dietary chemicals to microbial physiology and hypothesized host impacts.\n\nID: 42399364\nTitle: Sex-specific responses of finishing pigs to dietary protein restriction in nutrient utilization and nitrogen-related metabolites derived from gut microbiota.\nAbstract: This study was conducted to explore the effects of dietary protein restriction on growth performance, nutrient utilization, gut microbiota, and microbial metabolites in finishing pigs, as well as to elucidate potential sex-associated differences between gilts and barrows. A total of 36 gilts and 36 barrows at 110 days of age were allocated to six groups in a 3 × 2 factorial arrangement consisting of three dietary protein levels and two sexes. Dietary crude protein levels were 17%, 15%, and 13% during phase I, and 15%, 13%, and 11% during phase II. The whole feeding trial lasted 51 days. Overall, lowering dietary protein levels altered the digestibilities of crude protein, ether extract, calcium and phosphorus (P < 0.01), and exerted sex-specific influences on serum total protein and nitric oxide concentrations (P < 0.05). Among gut microbiota, five genera responded to protein restriction (P < 0.05), eight showed sex differences (P < 0.05), and six exhibited sex-specific responses to dietary protein levels (P < 0.05). Dietary protein restriction reduced gut microbiota-derived ammonia nitrogen and six of eight biogenic amines (P < 0.05); four of these metabolites differed between sexes (P < 0.05), and four showed protein × sex interactions (P < 0.05). The nitrogen-related metabolites were positively correlated with specific microbiota only in gilts (P < 0.05). In conclusion, dietary protein restriction induced sex-specific alterations in gut microbiota and nitrogen-associated metabolites in finishing pigs, and such metabolic responses were exclusively linked to microbiota changes in gilts but not in barrows.\n\nID: 42352465\nTitle: Cervicovaginal Microbiota and Biogenic Amine Metabolic Shifts in HPV-Associated Cervical Disease.\nAbstract: Background: Cervical cancer is primarily caused by the human papillomavirus (HPV), with persistent infections progressing to low- (LGSIL) and high-grade (HGSIL) lesions. Emerging evidence indicates that the cervicovaginal microbiota influences HPV persistence and disease progression, although the underlying metabolic mechanisms remain unclear. Therefore, we assessed the relationship between the cervicovaginal microbiota and the metabolic milieu in women with cervical dysplasia and HPV infections. Methods: We recruited 36 non-menopausal, non-pregnant women who were classified as negative, LGSIL, or HGSIL based on pathology and HPV results. Cervical swabs were collected for genomic DNA extraction to characterize bacterial communities using 16S rRNA sequencing and to perform HPV genotyping. Cervical lavages were collected for untargeted metabolomic profiling using Gas Chromatography-Mass Spectrometry. Integrative multiomic analysis was performed using the MIMOSA2 pipeline. Results: Although bacterial community structure was not different between groups, women with HGSIL had higher richness and exhibited a higher abundance of Prevotella bivia, Prevotella buccalis, and Lachnospiraceae G-9 oral taxon 924. Lesion-positive samples had shifts in tyramine and putrescine, biogenic amines linked to cancer development. Specifically, Pseudomonas was identified as a potential contributor to tyramine oxidation. Conclusions: Cervical lesions and HPV risk are associated with shifts in the cervicovaginal microbial metabolic milieu, highlighting the role of low-abundant anaerobic bacteria. Despite the small sample size, biogenic amines were associated with anaerobic taxa and microbial dysbiosis. These findings warrant further assessment of microbial-derived metabolites and their potential to promote tumor progression by driving a pro-inflammatory, metabolically altered microenvironment.\n\nID: 42283770\nTitle: Divergent Colorectal Cancer Risks Following Metabolic Bariatric Surgery: Anatomical Remodeling and the Genotoxic Microenvironment.\nAbstract: Metabolic bariatric surgery (MBS) reduces overall cancer incidence, yet colorectal cancer (CRC) risk diverges by procedure. Roux-en-Y gastric bypass (RYGB) has been associated with increased long-term CRC risk (HR 1.55 at 10-14 years), whereas sleeve gastrectomy (SG) shows no equivalent elevation, though shorter follow-up (mean 4.5 vs. 8.5 years) precludes definitive conclusions. This review develops a biologically plausible mechanistic framework for these divergent outcomes. RYGB-induced anatomical bypass and accelerated transit are proposed to drive distal substrate overload, with an associated shift of the colonic microbiome toward proteolytic fermentation. The proposed genotoxic luminal environment is characterized by convergent actions of secondary bile acids, tyramine, and hydrogen sulfide, compounded by butyrate depletion. By preserving gastrointestinal continuity, SG is hypothesized to avoid these alterations. These considerations support integrating baseline CRC risk into surgical selection and procedure-specific surveillance after RYGB.\n\nID: 42240953\nTitle: Phenotypic, Genomic, and In Vivo Characterization of a Host-Derived Limosilactobacillus fermentum RLF77 with Potential to Prevent Post-weaning Diarrhea in Rabbits.\nAbstract: Following the 2020 ban on antibiotic growth promoters in animal feed, diarrheal disease in weaned rabbits has become an increasingly important challenge for the rabbit industry. Due to their superior intestinal adaptability and colonization potential, host-derived probiotics are considered promising alternatives. In this study, Limosilactobacillus fermentum RLF77, a lactic acid bacterium, was isolated from the intestinal contents of healthy young rabbits. Strain RLF77 showed a favorable safety profile, including γ hemolysis, a negative indole reaction, and no production of biogenic amines. Furthermore, the strain exhibited strong tolerance to heat, acidic conditions, bile salts, and simulated gastrointestinal fluids, as well as broad antimicrobial activity against a range of enteric pathogens. It also displayed moderate cell surface hydrophobicity, auto-aggregation ability, and strong antioxidant activity. Whole genome sequencing revealed that RLF77 possesses a 2.31 Mbp genome enriched in genes involved in carbohydrate and amino acid metabolism, stress response, and oxidative defense. In addition, genome mining identified biosynthetic gene clusters putatively encoding enterolysin A. Oral administration in mice further supported the in vivo safety of RLF77 and significantly increased villus height and the villus height/crypt depth ratio. In an E. coli-challenged weaned rabbit model, dietary RLF77 supplementation improved growth performance, reduced diarrhea incidence, enhanced immune and antioxidant capacity, alleviated intestinal injury, and improved gut microbiota composition by increasing microbial richness and Akkermansiaceae abundance. Collectively, the host-derived strain L. fermentum RLF77 is a safe and promising probiotic candidate for improving intestinal health and preventing post-weaning diarrhea in rabbits.\n\nID: 42221754\nTitle: Functional fermented dairy products: a review of mechanisms, health potential, and technological challenges.\nAbstract: Fermented dairy products such as yoghurt, kefir and cheese are increasingly recognised as functional foods due to the metabolic activity of lactic acid bacteria and the associated microbial communities, including probiotics. During dairy fermentation, these microorganisms generate bioactive compounds, such as bioactive peptides, exopolysaccharides, organic acids and other metabolites, which may contribute to host health. There is emerging evidence that fermented dairy products can influence gastrointestinal function, immune regulation, metabolic health and cardiovascular risk, via mechanisms involving modulation of the gut microbiota, stabilisation of the epithelial barrier and inflammatory signalling pathways. In addition, fermentation may improve lactose digestion, enhance nutrient bioavailability, and generate peptides with anti-hypertensive or antioxidant properties. However, translating these results into consistent health benefits is challenging due to the significant variability in microbial strains, product composition, processing conditions and dosage. Safety considerations such as biogenic amines, sodium content, allergenicity and antimicrobial resistance also require careful monitoring. Future progress in this field will depend on improved product characterisation, strain-level identification and well-designed human intervention studies that integrate multi-omics approaches. In conclusion, fermented dairy products show great potential as a source of bioactive compounds, but more robust clinical evidence and standardised methodologies are required to firmly establish their role in promoting human health.\n\nID: 42153897\nTitle: Phosphate binders and the gut microbiota in chronic kidney disease: mechanisms, mixed evidence, and clinical considerations.\nAbstract: Chronic kidney disease (CKD) disrupts the gut microbiome through dietary restrictions, uraemia, and polypharmacy, including phosphate binders. This dysbiosis contributes to systemic inflammation, accumulation of uremic toxins, and reduced short-chain fatty acid (SCFA)-producing bacteria. Hyperphosphatemia, a key CKD complication, typically emerges in advanced stages. This review examines the impact of phosphate binders on gut microbiota and explores emerging biological therapies. Phosphate binders are standard treatment for hyperphosphatemia but may influence gut microbiota by altering luminal pH, intestinal transit, and availability of metabolites such as SCFAs and vitamin K. These changes can impair gut barrier integrity and promote inflammation. Evidence on their microbiome effects is mixed: some studies show minimal compositional changes with calcium acetate or sucroferric oxyhydroxide, while others report individual variability and subtle taxon-specific shifts, particularly with iron-based binders. Even when compositional changes are limited, certain binders may modulate uremic toxin levels. Given the limitations of conventional therapies, biological approaches such as probiotics, synbiotics, and phosphate-accumulating organisms (PAOs) are gaining interest. These strategies may reduce intestinal phosphate availability by lowering pH, enhancing calcium-phosphate binding, and promoting microbial phosphate uptake and storage, while supporting gut barrier function. Overall, current evidence remains heterogeneous and limited by small cohorts and preclinical designs. Although microbiota-targeted therapies show mechanistic promise, robust clinical trials are needed before they can be recommended beyond adjunctive use.\n\nID: 42134555\nTitle: Neural and metabolic mechanisms of emetogenic foodborne toxins via the brain-gut axis in ageing and cachexia.\nAbstract: Emetic foodborne toxins (bacterial enterotoxins, mycotoxins like DON/ZEA, marine toxins, cereulide, T-2 toxin, domoic acid, and biogenic amines such as histamine) cause acute gastrointestinal reactions and chronic systemic pathologies. This review outlines their activation of the brainstem's area postrema (AP) via intestinal barrier disruption, dysbiosis, vagus nerve stimulation, or direct central penetration. Acute exposure induces anorexia/defense responses through AP/NTS receptor pathways (GLP-1R, CCK, PYY, ghrelin, GDF15-GFRAL, 5-HT3). Chronic exposure impairs the AP-hypothalamus-locus coeruleus (LC) pathway, causing neuropsychiatric disorders, cachexia-like metabolic reprogramming, and multi-organ dysfunction. The gut microbiota play pivotal roles in toxin metabolism, bioactivation, and detoxification; microbial dysbiosis and LPS translocation amplify systemic inflammation. The elderly, immunocompromised individuals, and patients with comorbidities are particularly vulnerable due to weakened barriers, immunosenescence, and polypharmacy. This review elucidates the toxin-induced acute-to-chronic cascade via the gut-brain-neuro-metabolic network, discusses current limitations and future directions, and provides a theoretical basis for understanding chronic pathogenic mechanisms and complex comorbidities.\n\nID: 42123770\nTitle: Bioactive Compounds in Coffee: Metabolism, Bioavailability and Health Effects-A Review.\nAbstract: Coffee is a very popular psychoactive beverage with a complex composition. Besides its stimulant effect due to caffeine, it contains several bioactive compounds with antioxidant properties and potent metabolic activity. Its clinical efficacy is fundamentally determined by the bioavailability and metabolic fate of its constituents. The bioactive components of coffee, such as polyphenols, melanoidins, phytosterols, biogenic amines, and carotenoids, have notable antioxidant, anti-inflammatory, and immunomodulatory effects. This review aims to present the main bioactive components of coffee, their biological effects, mechanisms of action, and the influence of preparation methods and individual variability on metabolic outcomes in common chronic diseases. The data are synthesized from clinical, prospective, and interventional studies to examine how processing variables and biological metabolism influence the health-promoting potential of coffee antioxidants. Brewing methods like hot filtration optimize the extraction of these antioxidants. Individual clinical outcomes are further modulated by genetic polymorphisms and gut microbiota variability, which influence the activation of the cellular Nrf2 antioxidant defense pathway.\n\nID: 42115271\nTitle: Altered gut microbiota and metabolites in children with non-organic anorexia: a multi-omics integration study.\nAbstract: Gut microbiota alterations have been linked to childhood eating disorders, but the functional and metabolic changes in non-organic anorexia (NOA) remain poorly understood. This study aimed to characterize the gut microbial composition, function, and metabolic profiles in children with NOA using an integrated multi-omics approach. A case-control study was conducted involving 88 children aged 1-5 years (48 NOA, 40 healthy controls). Gut microbiota composition was assessed via 16S rRNA gene sequencing of all fecal samples. Subsequently, the five most representative samples from each group were selected for deep shotgun metagenomic sequencing and liquid chromatography-mass spectrometry (LC-MS) based non-targeted metabolomics. NOA children showed significantly higher microbial richness and diversity (Chao1, Shannon; P < 0.001). The NOA group had elevated Firmicutes, Bacteroidota, Bacteroides, Faecalibacterium, Subdoligranulum, and Roseburia, but reduced Actobacteriota, Bifidobacterium, and Enterococcus. Metagenomics revealed downregulated riboflavin metabolism and upregulated fat digestion/absorption pathways in NOA (P < 0.05). Metabolomics identified 26 differential fecal metabolites, including decreased L-carnitine derivatives and elevated tyramine glucuronide involved in bile secretion. These metabolites were significantly correlated with altered bacterial genera. Our integrated multi-omics analysis demonstrates that NOA in children is associated with a specific gut ecosystem characterized by altered microbiota structure, perturbed microbial metabolic functions (particularly riboflavin metabolism), and corresponding host-microbiota co-metabolic disturbances. These findings provide novel evidence for the disrupted \"microbiota-metabolite\" axis in NOA, offering new mechanistic insights.\n\nID: 42083198\nTitle: Squid cartilage-derived chondroitin sulfate from Uroteuthis chinensis: a novel marine prebiotic modulating gut microbiota and ameliorating ulcerative colitis.\nAbstract: This study evaluated the prebiotic potential of chondroitin sulfate (CS) derived from the cartilage of the squid Uroteuthis chinensis, and its protective effects against dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) in mice. Dietary intervention with squid-derived CS significantly attenuated characteristic UC symptoms, including body weight loss, colon shortening, and histopathological damage. Mechanistic analyses revealed that squid-derived CS exerted potent anti-inflammatory effects by downregulating key pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) and alleviated oxidative stress by enhancing colonic antioxidant capacity, as evidenced by increased activities of catalase (CAT) and superoxide dismutase (SOD) and reduced myeloperoxidase (MPO) activity. Integrated 16S rRNA gene sequencing and metabolomics analyses demonstrated that squid-derived CS profoundly restructured gut microbial community composition by enriching putative beneficial bacteria (e.g., Bifidobacterium, Clostridium, Blautia) while reducing opportunistic pathogens (e.g., Enterococcus, Sutterellaceae, Clostridia_UCG-014). This favorable microbial shift was accompanied by a reconfiguration of the intestinal metabolome, characterized by elevated production of beneficial short-chain fatty acids (SCFAs) and decreased levels of pro-inflammatory metabolites such as tyramine. Furthermore, squid-derived CS effectively enhanced intestinal barrier integrity by upregulating key tight junction proteins (ZO-1, occludin, claudin-1), thereby preventing bacterial lipopolysaccharide (LPS) translocation and associated liver injury, as indicated by reduced serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Collectively, these findings demonstrate that dietary squid-derived CS protects against UC by modulating gut microbiota composition to enrich beneficial taxa, restoring microbial metabolite homeostasis, reinforcing the intestinal epithelial barrier, and suppressing inflammatory responses and oxidative stress. This study provides the first evidence that squid-derived CS acts as a novel and promising marine prebiotic candidate for gut health promotion, highlighting its potential as a sustainable functional ingredient derived from processing waste for gut-health-promoting foods.\n\nID: 42061249\nTitle: Gut health in broiler chickens fed a mixture of Hermetia illucens and Tenebrio molitor meals: does it have a key role in shaping bird performance?\nAbstract: Insect meals are promising sustainable protein sources for poultry, but comprehensive insights into their effects on gut health and growth performance are lacking. This study is the first to elucidate relationships between gut health parameters and performance in broilers fed Hermetia illucens (HI) and Tenebrio molitor (TM) meals at 5% or 10% inclusion levels, singly or in a 1:1 combination. A 37-day trial used 420 male Ross 308 chicks randomly allocated to seven treatments: control (C), HI5 (5% HI), HI10 (10% HI), TM5 (5% TM), TM10 (10% TM), MIX5 (5% MIX), and MIX10 (10% MIX). By integrating intestinal histomorphometry, mucin histochemistry, multi-organ histopathology, and multi-omics cecal microbiome characterization, we identified key structural, microbial, and metabolic biomarkers associated with performance variations (false discovery rate [FDR]<0.05 and P < 0.05 for microbiome and histomorphology, respectively). High-performing groups (MIX5, TM5) showed microbiomes enriched in short-chain fatty acid-producing bacteria (Veillonellaceae, Butyricicoccus, Limosilactobacillus crispatus), positively correlated with ADG and ADFI (FDR<0.05) and negatively correlated with FCR (FDR<0.05). Favorable metabolomic profiles (increased dopamine, tyramine, malic and orotic acids; reduced 3-deoxyglucosone, hexanoylcarnitine [FDR<0.05]) and preserved balance between neutral (positively correlated with BW and ADFI [P < 0.05]) and acidic mucins (positively correlated with BW, ADFI and ADG, and negatively correlated with FCR [P < 0.05]) were also observed. Low-performing groups (MIX10, HI10) displayed microbiomes dominated by Ruminococcaceae, Alistipes, and l-Eubacterium (negatively correlated with FCR and associated with purine metabolism alterations [FDR<0.05]), alongside worsened morphology (tendency for reduced villus height in MIX10 [P = 0.07], positively and negatively correlated with ADG and FCR, respectively [P < 0.05], and thinner mucosal/muscular layers [P < 0.05]) and decreased neutral mucins (P < 0.05). TM10 maintained unaffected growth performance via beneficial taxa (Limosilactobacillus crispatus, Tyzzerella), and reduced Campylobacter jejuni and antimicrobial resistance genes (FDR<0.05). Jejunal inflammation, negatively correlated with ADG (P < 0.05), was not influenced by dietary treatments (P > 0.05). In conclusion, specific taxa (Butyricicoccus, Veillonellaceae, Limosilactobacillus crispatus), metabolites (dopamine, tyramine, malic and orotic acids), and mucosal features (villus height, mucin composition) were identified as biomarkers of optimal performance in insect-fed broilers.\n\nID: 42042907\nTitle: Effects of Probiotic Supplementation on Gut Microbiota and Fecal Metabolome in Autism Spectrum Disorders: A Secondary Analysis of a Randomized Clinical Trial in Preschoolers.\nAbstract: Recently, a randomized clinical trial evaluated whether a six-month probiotic administration could reduce symptom severity in preschool children with Autism Spectrum Disorders (ASD), with (GI) or without (NGI) gastrointestinal symptoms. Significant positive changes were observed only in NGI children. A second explorative study on children prior to intervention identified a fecal metabolome fingerprint associated with ASD severity. Building on these findings, the present study aimed to assess whether metabolomics could monitor changes in ASD severity following probiotic administration using a subset of samples from the same trial. Second, this study aimed to identify fecal metabolites to be monitored in children to predict whether their autism severity may decrease after probiotic or placebo treatment. Evaluations of the fecal metabolome and microbiota could be completed on 57 children before and after a double-blind administration of a probiotic mixture or a placebo. In NGI children the probiotic was found to influence the concentration of the amino acids aspartate, leucine, tryptophan, and valine, together with nicotinate and the short chain fatty acids acetate, butyrate, isobutyrate, and propionate. Lactobacilli and Sutterella showed significant changes in response to probiotic administration (p < 0.05). Acetate, 4-hydroxyphenyl, galactose, proline, and tyramine were identified as key fecal metabolites for prediction purposes. The present exploratory analysis, despite the small sample size, suggests that fecal metabolomics may provide a useful approach for monitoring and potentially for predicting changes in ASD severity following probiotics administration.\n\nID: 41956455\nTitle: Dietary Fiber in Sport: Implications for Performance and Body Composition Optimization.\nAbstract: Although dietary fiber is widely recognized for its health benefits in the general population, including reduced risk of cardiovascular disease and improved metabolic regulation, its role in athletic performance and recovery remains comparatively underexplored. Current sports nutrition guidelines lack specific recommendations for fiber intake, despite evidence linking adequate consumption to gut microbiome stability, immune modulation, and body composition optimization. Athletes face unique physiological demands that influence gastrointestinal tolerance, nutrient absorption, and energy availability, particularly under high training loads. Although excessive fiber intake may lead to gastrointestinal discomfort or reduced caloric intake, moderate and periodized consumption has been associated with enhanced immune function, improved energy metabolism, and preservation of skeletal muscle mass. Recent findings suggest potential benefits in attenuating exercise-induced inflammation and regulating substrate utilization. Nevertheless, observational data indicate that many athletes fail to meet general population intake targets, often due to precompetition dietary restrictions or concerns about digestive comfort. This review critically synthesizes current evidence on the physiological impacts of dietary fiber in athletic populations, focusing on gastrointestinal health, immune function, body composition, and performance outcomes. It further outlines practical, evidence-based strategies to optimize intake according to individual needs and sport-specific demands, including fiber periodization, source selection, and gradual adaptation.\n\nID: 41843249\nTitle: Lactose intolerance and probiotics: from pathophysiological mechanisms to clinical applications.\nAbstract: Lactose is a disaccharide found in dairy products, which provide energy and essential nutrients. Digestion of lactose relies on the intestinal enzyme lactase, or lactase-phlorizin hydrolase, located on the brush border of the small bowel mucosa. This enzyme splits lactose into two absorbable monosaccharides: glucose and galactose. When lactase activity is insufficient, undigested lactose proceeds to the colon where it is fermented by the gut flora, generating gas that trigger the uncomfortable symptoms associated with lactose intolerance. Lactase non-persistence is extremely common, affecting approximately 70% of the adult population world-wide. Prevalence varies markedly across geographic regions, typically ranging from 50 to 90% in African, Asian, and South American countries. The subjective diagnosis of lactose intolerance requires the occurrence of symptoms such as abdominal pain, bloating, flatulence and diarrhea following the ingestion of high lactose dairy products. An objective assessment of lactose intolerance may be achieved with a specific breath test that measures hydrogen emission in breath following the ingestion of lactose. Consequently, current international guidelines require concurrent report of typical symptoms and pathologic breath test results in order to diagnose lactose intolerance. Management of lactose intolerance often involves dietary restrictions and the prescription of formulations that contain lactase. However, one should recognize that avoiding dairy products can increase the risk of nutritional deficiencies. Therefore, ongoing research is focused on alternative strategies, notably utilizing gut microbiota in order to improve tolerance to lactose. This review aims to explore the evidence supporting the use of probiotics as a potential treatment strategy to alleviate the symptoms of lactose intolerance by modulating colonic metabolism and enhancing lactose digestion.\n\nID: 41840712\nTitle: Characterization of age-related changes in the gut microbiome and metabolome of Kunming dogs and their associations with police performance.\nAbstract: Gut microbiota plays a pivotal role in regulating the host's central nervous system (CNS) activity and behavior. However, its influence on the police performance of Kunming dogs and the underlying mechanisms remain largely unexplored. This study was the first to apply multi-omics technologies to investigate the dynamic variations in gut microbiota and their metabolic profiles across different ages of Kunming dogs. Furthermore, we systematically examined the associations between these microbial alterations and police performance metrics, providing a theoretical foundation for enhancing the working capabilities of Kunming dogs through targeted modulation of intestinal microecology. The study showed that puppies, young dogs and adult dogs had significantly better police performance than elderly dogs, with young dogs exhibiting the highest scores. Analysis of 16S rRNA sequencing demonstrated that gut microbial diversity and stability were highest during the young dog stage, gradually declining with age. Metagenomic analysis revealed that the abundance of Lactobacillus acidophilus, Lactobacillus johnsonii, Limosilactobacillus reuteri, Ligilactobacillus animalis and Muribaculum gordoncarteri were strongly correlated with police performance. The results of metagenome-assembled genomes (MAGs) indicated that the above species have functional genes involved in GABAergic and glutamatergic synapse pathways. Furthermore, metabolomic analysis showed that differential metabolites were enriched in the neuroactive ligand-receptor interaction pathway, in which GABA (γ-aminobutyric acid), histamine and tyramine metabolites were positively correlated with the above species and police performance. The species L. acidophilus, L. johnsonii, L. reuteri, L. animalis, and M. gordoncarteri, which were enriched in the gut of puppies and young Kunming dogs, may potentially influence the nervous system through the production of neurotransmitters and neuromodulators, suggesting a possible association with police performance.

This survey aims to assess nutritional awareness regarding liver disease among healthcare providers (hepatologists and non-hepatologists). METHODS: A structured online questionnaire was created based on clinical knowledge and established guidelines related to nutrition in liver disease. The survey consisted of 13 questions addressing nutritional considerations for liver disease patients. RESULTS: A total of 124 out of 362 survey recipients responded. Among them, 60.5% were hepatologists, while the remaining respondents included general practitioners, endocrinologists, and cardiologists. Hepatologists were more likely than non-hepatologists to recognize the significance of nutritional guidance for their patients, with 74.7% of hepatologists supporting this view compared to only 40.8% of non-hepatologists (p < 0.001). For patients with compensated cirrhosis, 82.7% of hepatologists preferred no dietary restrictions, whereas only 46.9% of non-hepatologists agreed (p < 0.001). Both groups favored protein restriction in cases of hepatic encephalopathy, (p = 0.2). Regarding patients with ascites, both hepatologists and non-hepatologists recommended salt restriction, with hepatologists showing a stronger inclination. When it comes to alcohol consumption, 80% of hepatologists and 61.2% of non-hepatologists favored restricting alcohol intake in patients with chronic liver disease (p = 0.03). CONCLUSION: There are notable differences in nutritional priorities and recommendations between hepatologists and non-hepatologists. There is a pressing need to raise awareness among non-hepatologist physicians concerning dietary recommendations for patients with chronic liver disease.\n\nID: 41779254\nTitle: Microbiome alterations and their potential impact on infection risk in chronic kidney disease and end-stage kidney disease: a narrative review.\nAbstract: Chronic kidney disease [CKD] is associated with profound alterations of both gut microbiota composition and functions, commonly referred to as gut dysbiosis. These changes are driven by several factors such as dietary restrictions, medications, and uremia, which further contribute to patients with CKD to their pro-inflammatory and immunocompromised state. Recent evidence suggests that dysbiosis may also increase susceptibility to infections, which remain a leading cause of morbidity and mortality in CKD patients. In this review, we aimed at examining the features of the altered gut microbiome in patients with CKD, its potential role in promoting infection risk, and current therapeutic strategies targeting the gut microbiota to mitigate CKD-related complications.\n\nID: 41754858\nTitle: Diet and Gut Microbiota in Inflammatory Bowel Disease: A Clinical and Nutritional Perspective.\nAbstract: Inflammatory bowel diseases, comprising Crohn's disease and ulcerative colitis, represent chronic inflammatory disorders with rising global incidence, underscoring the pivotal role of modifiable environmental factors in disease pathogenesis. Diet and intestinal microbiota have emerged as critical bidirectional therapeutic targets through complex interactions with host immune responses. Epidemiological evidence demonstrates that healthy and high fiber diets reduce disease risk, while ultra-processed foods and inflammatory dietary patterns increase susceptibility. Therapeutic nutritional interventions, including exclusive enteral nutrition, the Crohn's Disease Exclusion Diet combined with partial enteral nutrition, and the Mediterranean diet can induce and maintain clinical remission while promoting favorable microbiome modifications characterized by the enrichment of butyrate-producing taxa such as Faecalibacterium prausnitzii and Roseburia species, alongside a reduction in pathogenic Proteobacteria. Micronutrient deficiencies affect up to 78% of patients through malabsorption, chronic blood losses, dietary restrictions, and drug-nutrient interactions. Nutritional status significantly impacts surgical outcomes, with preoperative malnutrition and sarcopenia associated with increased postoperative complications, and it reciprocally influences biologic therapy response. Integration of personalized, microbiome-informed dietary strategies as complementary components of comprehensive treatment plans represents a promising therapeutic frontier, requiring multidisciplinary collaboration, rigorous clinical trials with standardized microbiome analyses, and precision nutrition algorithms accounting for disease phenotype, baseline microbial composition, and individual patient characteristics to optimize outcomes and improve quality of life.\n\nID: 41730497\nTitle: How cytochrome P450 enzymes in humans are involved in Parkinson's disease: a literature review.\nAbstract: This review synthesizes three decades of evidence regarding the role of cytochrome P450 enzymes (CYPs) in Parkinson's disease (PD), revealing their multifaceted roles beyond traditional pesticide metabolism. While CYP2D6 remains the most studied enzyme due to its association with PD risk in poor metabolizer phenotypes and its dual role in dopamine (DA) synthesis (directly via tyramine hydroxylation and indirectly through precursor demethylation), recent research has highlighted less-studied CYPs with critical pathological implications. Another focal enzyme, CYP2E1, mediates the bioactivation of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine to its neurotoxic metabolite, 1-methyl-4-phenylpyridinium, thereby inducing oxidative stress. It also partially contributes to DA oxidation, a process that generates multiple cytotoxic byproducts. These toxic products are implicated in two major pathological processes involved in the development of PD-oxidative stress and protein misfolding-which adversely affect dopaminergic neurons. Additionally, CYP3A4 converts acetaminophen to N-acetyl-p-benzoquinone imine in the substantia nigra, contributing to dopaminergic neuron loss. Emerging enzymes like CYP7B1 (which reduces midbrain DA neuron survival via 7α,26-dihydroxycholesterol) and CYP46A1 (inhibiting α-synuclein aggregation) further expand the involvement of the CYP network in PD. The CYP4 family has also emerged as regulators of fatty acid and eicosanoid metabolism, linking to neuroinflammation and oxidative stress. While CYP2D6 and CYP2E1 have dominated prior studies, this review underscores the broader impact of the CYP superfamily on PD pathogenesis through interconnected pathways involving xenobiotic detoxification, fatty acid homeostasis, cholesterol clearance, and neuroinflammation. By integrating these diverse mechanisms, this study establishes a multifactorial framework that connects CYP-mediated biochemical cascades to PD pathogenesis. SIGNIFICANCE STATEMENT: This article addresses the role of various Cytochrome P450 enzymes (CYPs) in Parkinson's disease (PD), covering both their biochemical functions and how genetic, epigenetic, and environmental factors influence PD progression. Recent findings on CYPs, particularly CYP2D6 and CYP2E1, and their involvement in PD pathogenesis through mechanisms such as pesticide metabolism, dopamine synthesis, and oxidative stress, are summarized. We also explore the contribution of lesser-studied CYPs, like CYP46A1 and CYP39A1, in cholesterol and fatty acid metabolism, presenting novel insights for therapeutic development. The review additionally touches on the influence of CYPs on disease biomarkers and therapeutic strategies, which may hold potential for both clinical application and personalized treatment of PD. Unlike prior reviews focused on CYP2D6 and CYP2E1, this work consolidates evidence for a broader CYP network in PD, highlighting novel therapeutic targets in cholesterol and fatty acid metabolism pathways.\n\nID: 41683364\nTitle: Fermented Foods and the Gut-Liver Axis: Modulation of MASLD Through Gut Microbiota.\nAbstract: Background/Objectives: Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) is a prevalent condition defined by hepatic fat accumulation, inflammation, and metabolic dysregulation. Current evidence demonstrates that gut microbiota and their metabolites are associated with MASLD pathogenesis. Fermented foods, rich in live microbes and bioactive compounds, actively modulate the gut-liver axis and influence disease progression. This narrative review provides a comprehensive summary of current evidence on the impact of fermented foods on gut microbiota, intestinal barrier function, and gut-liver interactions, and demonstrates their potential role in preventing or mitigating MASLD. Methods: A comprehensive literature search of preclinical and clinical studies was conducted. Specifically, the review focused on fermented-food interventions, modulation of gut microbiota, metabolite production, and effects on hepatic metabolism and inflammation. Results: This review found that fermented foods provide probiotics, prebiotics, short-chain fatty acid (SCFAs), and bioactive compounds that enhance microbial diversity, improve intestinal barrier integrity, reduce endotoxemia, and modulate bile acid and lipid metabolism. Evidence from animal and human studies indicates that fermented food consumption can attenuate hepatic steatosis, inflammation, and metabolic dysregulation, with variability depending on individual microbiome composition. Conclusions: Altogether, these findings suggest that fermented foods represent a promising adjunctive dietary strategy for MASLD by modulating the gut-liver axis and supporting metabolic and hepatic health. Personalized approaches and further long-term clinical trials are required to optimize interventions and establish evidence-based recommendations.\n\nID: 41672155\nTitle: Nutritional and metabolic signatures in pediatric phenylketonuria and hyperphenylalaninemia: Insights from untargeted urinary metabolomics.\nAbstract: Dietary interventions are essential for managing phenylketonuria (PKU) and may influence metabolic regulation beyond phenylalanine control. We characterized the urinary metabolomic fingerprint of pediatric participants (n=82) recruited into clinical phenotypes: PKU, PKU with response to tetrahydrobiopterin (BH4), and hyperphenylalaninemia (HPA), as well as sex- and age-matched healthy children controls. Untargeted metabolomics (HPLC-Q-TOF-MS/MS) revealed 59 discriminant metabolites across multiple biochemical pathways, including phenylalanine, tryptophan, and caffeine metabolisms, as well as metabolites related to dietary exposure or gut microbial metabolism. Distinct urinary signatures were described across phenotypes. Phenylalanine-related pathways predominated in PKU, accompanied by increased excretion of vitamin derivatives, consistent with protein substitute supplementation. In contrast, reduced levels of non-phenylalanine amino acid derivatives, methylhistidines, creatine, and branched-chain amino acid-related metabolites were observed in PKU, suggesting alterations in muscle metabolism or natural protein intake. Microbiota-derived metabolites were also less represented in PKU, indicating potential effects of dietary restrictions on gut-host metabolic interactions. HPA individuals showed a urinary fingerprint closer to controls, whereas the BH4 subgroup exhibited the greatest metabolic heterogeneity, reflecting variability in dietary and pharmacological treatment responses. These findings reveal metabolic diversity within the pediatric PKU spectrum driven by clinical phenotype and nutritional management. Urinary metabolomics may support more precise monitoring of metabolic health status and guide precision nutrition strategies in PKU and HPA from early life.\n\nID: 41630915\nTitle: Commensal human gut microbes produce species specific neuroactive compounds.\nAbstract: The gut microbiota communicates with multiple organs through neuroactive molecules, but the specific compounds produced remain unclear. We investigated eight commensal gut species, Lactococcus lactis, Enterococcus faecalis, Blautia producta, Clostridium symbiosum, Streptococcus thermophilus, Prevotella copri, Bacteroides fragilis, and Escherichia coli Nissle, using targeted and non-targeted LC-MS/MS. These bacteria differentially consumed glutamine, glutamate, and tryptophan, producing distinct neuroactive metabolites. For example, E. coli and B. producta generated high levels of gamma-aminobutyric acid (GABA), while P. copri was the sole producer of tryptamine. In the tyrosine pathway, E. faecalis synthesized tyramine and dopamine, and L. lactis, B. producta, and E. coli produced L-DOPA. Interestingly, none produced serotonin or its intermediates despite consuming tryptophan. Multiple species also generated short-chain fatty acids (SCFAs). These findings demonstrate that commensal microbes contribute to host neurochemistry by producing diverse neuroactive metabolites and SCFAs, highlighting the therapeutic potential of modulating the gut microbiota to influence human health.\n\nID: 41615647\nTitle: Correlation analysis of gut microbiota and metabolites in gastric cancer patients in plateau areas based on multi-omics technologies.\nAbstract: To characterize gut microbiota alterations and metabolic changes in gastric cancer (GC) patients from high-altitude regions using 16S rDNA sequencing and untargeted metabolomics. Fecal samples from 30 GC patients and 30 healthy controls in Qinghai Province were analyzed. Microbial diversity and composition were assessed via 16S rDNA sequencing, and metabolite profiles were determined using untargeted metabolomics. Correlations between significantly altered microbial taxa and metabolites were evaluated. Microbial diversity differed significantly between groups (P < 0.001). Proteobacteria abundance was higher in GC patients (P < 0.05). At the genus level, Prevotella_9, Streptococcus, and Lactobacillus showed significant differences (P < 0.05-P < 0.001). GC patients exhibited upregulation of desulfo-biotin, glycylproline, glycine, hydroxyhexanoic acid, tyramine, methanethiol oxidase, 5-aminopentanoic acid, citrulline, betaine, and formyl glutamic acid, and downregulation of cytidine, 5'-methylthioadenosine, trehalose, melezitose, lotaustralin, adenosine, creatinine, 5-methyluridine, raffinose, and galactitol. Proteobacteria correlated positively with desulfo-biotin, glycylproline, and glycine, while Lactobacillus correlated with several upregulated metabolites including tyramine and betaine (all P < 0.05). Cytidine correlated negatively with Proteobacteria, whereas creatinine and 5-methyluridine correlated positively with Prevotella_9. GC patients in high-altitude regions display distinct gut microbiota and metabolite profiles, with notable microbe-metabolite associations. These findings suggest potential biomarkers and therapeutic targets for GC in plateau populations.\n\nID: 41595985\nTitle: Gut Microbiota and Dopamine: Producers, Consumers, Enzymatic Mechanisms, and In Vivo Insights.\nAbstract: The human gut microbiota plays a key role in neurochemical communication, especially through the gut-brain axis. There is growing evidence that the gut microbiota influences dopamine metabolism through both production and consumption mechanisms. Two key bacterial enzymes are central to this process: tyrosine decarboxylase (TDC), which primarily catalyzes the decarboxylation of tyrosine to tyramine but can also act on L-DOPA to produce dopamine in certain bacterial strains, and aromatic L-amino acid decarboxylase (AADC), which can convert precursors such as L-DOPA, tryptophan, or 5-hydroxytryptophan into bioactive amines including dopamine, tryptamine, and serotonin. Identifying the bacterial families corresponding to TDC and AADC enzymes opens new avenues for clinical intervention, particularly in neuropsychiatric and neurodegenerative disorders, such as Parkinson's disease. Moreover, elucidating strain-specific microbial contribution and host-microbe interactions may enable personalized therapeutic strategies, such as selective microbial enzyme inhibitors or tailored probiotics, to optimize dopamine metabolism. Emerging technologies, including biosensors and organ-on-chip platforms, offer new tools to monitor and manipulate microbial dopamine activity. This article explores the bacterial taxa capable of producing or consuming dopamine, focusing on the enzymatic mechanisms involved and the methodologies available for studying these processes in vivo.\n\nID: 41582363\nTitle: Clinical Features of Hypo- and Hypervitaminosis of Fat-Soluble Vitamins in Pediatric Patients.\nAbstract: Fat-soluble vitamins (A, D, E, and K) are crucial for pediatric health, contributing to normal cellular function, growth, immune defense, and development. Unlike water-soluble vitamins, they are absorbed with dietary fats and stored in the liver and adipose tissue, leading to risks of deficiency (hypovitaminosis) and toxicity (hypervitaminosis) in certain physiological and pathological conditions. This narrative review aimed to summarize the clinical manifestations, diagnostic considerations, and management of hypo- and hypervitaminosis of fat-soluble vitamins in pediatric populations. A comprehensive literature review was conducted, highlighting the physiological roles, symptoms of deficiency and toxicity, diagnostic strategies, and treatment options, with particular focus on high-risk groups, including neonates and children with malabsorption or dietary restrictions. Pediatric patients are especially vulnerable to vitamin imbalances due to rapid growth and specific developmental needs. Deficiencies can result in vision problems, bone disorders, immune dysfunction, and coagulation issues, while excess intake can lead to toxicity. Management strategies include clinical assessment, biochemical testing, supplementation, dietary counseling, and public health interventions. Early detection and preventive measures are essential. Future research is needed to explore non-classical roles of these vitamins and optimize supplementation guidelines.\n\nID: 41552834\nTitle: A sulfotransferase from a gut microbe acts on diverse phenolic sulfate compounds, including acetaminophen sulfate.\nAbstract: Sulfonation is one of the two main phase II detoxification pathways in eukaryotes which transforms nonpolar compounds into hydrophilic metabolites. Sulfotransferases catalyze these reactions by transferring a sulfo group from a donor to an acceptor molecule. Human cytosolic sulfotransferases use only 3'-phosphoadenosine 5'-phosphosulfate (PAPS) as a donor to sulfonate a variety of chemicals. Less understood are microbial aryl-sulfate sulfotransferases (ASSTs), which catalyze sulfo transfer reactions, without utilizing PAPS as a donor. Currently, the identity of physiological sulfo donor substrates remains unknown and sulfo acceptor substrates are underexplored. With this study, we aim to understand the potential contribution of a gut microbial enzyme to sulfonation chemistry by uncovering its substrate preferences. Here, we show that a sulfotransferase (Bacteroides vulgatus ASST) from the prevalent gut microbe B. vulgatus (now Phocaeicola vulgatus) is a versatile catalyst that utilizes a wide range of phenolic molecules as substrates that are commonly encountered by the host. With this action, it modulates concentrations of donor phenolic sulfates such as acetaminophen sulfate, dopamine sulfate, p-cresol sulfate, and related compounds in vitro and displays broad acceptor flexibility by sulfonating diverse phenolic compounds, including p-coumaric acid, p-cresol, 4-ethylphenol, tyramine, among others. These findings suggest that gut microbial enzymes like ASSTs may contribute to host detoxification of phenolics, a role previously attributed solely to human sulfotransferases. However, further in vivo studies are necessary to understand the potential contributions of ASSTs to host detoxification processes.\n\nID: 41550498\nTitle: The TAAR1 antagonist EPPTB ameliorates colitis via serotonin inhibition.\nAbstract: Inflammatory bowel disease (IBD) is characterized by gut dysbiosis and impaired microbial metabolite signaling. Emerging evidence suggests that gut microbial metabolites, such as trace amines (tryptamine, phenethylamine, and tyramine), function as endogenous TAAR1 agonists and may contribute to IBD pathogenesis. Our study identified elevated fecal trace amine levels in ulcerative colitis (UC) patients and DSS-induced colitis mice. In vitro, exposure to these trace amines enhanced 5-HT secretion in QGP-1 cells and ex vivo mouse colonic tissues, and this effect could be blocked by the TAAR1 antagonist EPPTB. In vivo, EPPTB treatment significantly mitigated DSS-induced colitis, as demonstrated by reduced weight loss, improved disease activity index (DAI), preserved colon length, and attenuated histopathological damage. Moreover, TAAR1 blockade reduced pro-inflammatory cytokines (TNF-α, IL-6, IL-1β) and increased IκB-α expression, restored intestinal barrier integrity (upregulating occludin and ZO-1, while downregulating cclaudin-2), and lowered colonic 5-HT levels by suppressing TPH1 expression. These findings suggest that TAAR1 inhibition alleviates colitis by modulating 5-HT signaling, positioning it as a promising therapeutic target for IBD.\n\nID: 41539433\nTitle: Fermented and non-fermented pickles modulate gut microbiota in older adults with dysphagia: A pilot crossover study.\nAbstract: Dysphagia is common among older adults and often leads to dietary restrictions, reduced appetite, malnutrition, and decreased quality of life. Although pickles are widely enjoyed by older adults, dysphagia-friendly pickles are often avoided owing to their texture. Moreover, many dysphagia-friendly foods are non-fermented and lack live lactic acid bacteria, and it remains unclear whether texture-modified, non-fermented pickles can favorably influence the gut microbiota. Therefore, this exploratory, microbiotal-focused study examined preliminary, taxon-level gut microbiotal signals associated with dysphagia-adapted non-fermented versus fermented pickles. In this pilot, single-blind, 2 × 2 crossover study, participants were alternately allocated to receive non-fermented or fermented pickles (finely shredded sauerkraut cut into 1-mm strips) first, with a 2-week washout between periods. Fecal samples were collected before and after each intervention. The gut microbiotal composition was analyzed using 16S rRNA gene amplicon sequencing and bioinformatic processing via QIIME2. Microbial diversity and taxonomic changes were analyzed using Wilcoxon's signed-rank test. Finally, α-diversity (Shannon, Chao1, Simpson), β-diversity (Bray-Curtis permutational multivariate analysis of variance), and taxon-level relative abundances for prespecified taxa (e.g., Bifidobacterium, SCFA-associated taxa) were evaluated. Thirteen participants were enrolled. There were no significant post-intervention changes in α-diversity (e.g., shannon p = 0.273, 0.414) and β-diversity (p = 0.993, 0.999). However, consumption of non-fermented pickles significantly increased the abundance of Actinobacteriota, including Bifidobacteriales, Bifidobacteriaceae, and Bifidobacterium (p = 0.012). In contrast, consumption of fermented pickles significantly increased the abundance of several short-chain fatty acid-associated taxa, including [Eubacterium] coprostanoligenes group and Marvinbryantia genus. Texture-modified pickles and fermented pickles can be safely provided and feasibly consumed by older adults with dysphagia risk. Their consumption induced modest, taxon-specific shifts in gut microbial composition, without altering global diversity. These exploratory pilot findings demonstrate feasibility and suggest taxon-level trends requiring confirmation in larger, randomized trials with functional and clinical endpoints.

Standard therapy traditionally combines immunosuppression with or without hematopoietic stem cell transplantation, and more recently incorporates thrombopoietin receptor agonists to stimulate residual hematopoiesis. Eltrombopag improved outcomes when added to immunosuppressive therapy, but its association with hepatotoxicity limits its suitability for patients with underlying liver disease or elevated baseline liver enzymes. Avatrombopag is a newer oral thrombopoietin receptor agonist that does not require dietary restrictions and does not undergo significant hepatic metabolism, which offers a potential therapeutic advantage in settings where liver function is compromised. This review evaluated ten clinical studies published from 2023 to October 2025 that investigated avatrombopag in acquired aplastic anemia across varied patient populations, including treatment-naive, relapsed or refractory cases, older adults, and patients with secondary aplastic anemia related to chemoradiation. Across these studies, overall response rates ranged from 55% to 85%, and complete response rates reached up to one-third of treated patients. Response onset typically occurred within 1-2 months, which aligns with clinical decision timelines for assessing therapeutic benefit. Avatrombopag supported reductions in transfusion requirements and sustained hematologic improvement in both severe and non-severe disease. Patients previously intolerant or non-responsive to eltrombopag also demonstrated clinical improvement, which suggests pharmacologic differences translate into meaningful therapeutic effects. Importantly, avatrombopag demonstrated a favorable safety profile in all reviewed settings. Reports did not identify clinically relevant hepatotoxicity, clonal evolution, or treatment-limiting adverse effects. Its tolerability in patients with liver dysfunction distinguishes it from earlier agents in this drug class. Ongoing trials will clarify optimal dosing strategies and define its future role within first-line therapy and salvage treatment pathways for aplastic anemia. A new treatment option for aplastic anemia: how avatrombopag may help patients with fewer side effects Aplastic anemia is a rare but serious disease where the bone marrow stops making enough blood cells. People with this condition often feel tired, bruise easily, or get frequent infections. The standard treatment for those who can’t get a bone marrow transplant is a combination of medications that suppress the immune system. Another helpful medicine, eltrombopag, boosts blood cell production but can harm the liver, which limits its use in some patients. Avatrombopag is a newer medicine that also stimulates blood cell production but seems to be safer for the liver. It’s taken as a pill and does not interact with food or most other drugs. This review looked at eight studies from 2023 and 2024 to understand how well avatrombopag works and how safe it is. The studies included patients with different types and severities of aplastic anemia, including older adults and those with liver problems. Overall, more than half of the patients improved with avatrombopag, and some fully recovered. Most people began feeling better within one to two months. Avatrombopag was helpful even for people who didn’t respond to other treatments. It caused few side effects and did not damage the liver. Some patients even had improved liver function during treatment. These results suggest that avatrombopag is a promising new treatment for aplastic anemia. It may offer a better and safer option for patients, especially those who can’t tolerate other drugs. More research is underway to confirm these findings and explore its role in standard treatment plans.\n\nID: 41462699\nTitle: Hepatoprotective, Antioxidant, and Anti-Hyperlipidemic Effects of Kefir Milk in High-Fat Diet-Induced Obesity: Insights from Gas Chromatography-Mass Spectrometry Profiling, Molecular Docking of Kefiran, and Liver Function Restoration.\nAbstract: The prevalence of chronic diseases, including obesity and related endocrine disorders, has risen significantly in recent decades. As a result, there has been growing interest in fermented foods with probiotic properties, such as kefir, which have potential health benefits. This study aimed to evaluate the hepatoprotective and antioxidant effects of kefir milk (KM) in a high-fat diet (HFD)-induced obesity rat model, complemented by in silico molecular docking studies with antioxidant enzymes. Twenty-four adult rats were divided into four groups: control (1 mL/100 g bw semi-skimmed cow milk), KM (1 mL/100 g bw kefir milk), HFD (1 mL/100 g bw semi-skimmed cow milk + high-fat diet), and KM/HFD (1 mL/100 g bw kefir milk + high-fat diet). After 60 days of treatment, biochemical assays and histological examinations were performed to assess the effects on lipid profiles and organ health. Kefir milk demonstrated significant antioxidant activity, with increased total phenolic content and enhanced DPPH, ABTS, and FRAP radical scavenging activities compared to commercial milk. Furthermore, KM administration protected against liver metabolic disruptions (ALT, AST, and LDH) induced by the high-fat diet and reduced lipid peroxidation in liver and testis tissues. KM supplementation also increased the activity of key antioxidant enzymes, including superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx). Additionally, KM improved the fatty acid composition and decreased the de novo lipogenesis (DNL) index, as well as enzyme activities (SCD and Elovl6) associated with the high-fat diet. Histological analysis of liver, pancreas, and heart tissues revealed that kefir milk attenuated structural damage caused by the high-fat diet, suggesting its protective role in oxidative stress regulation and organ function. These findings underscore the potential of kefir milk as a functional food for preventing metabolic disturbances and liver damage associated with obesity.\n\nID: 41429111\nTitle: A therapeutic gastrointestinal diet improves nutrient digestibility and modulates fecal microbiota and metabolites in dogs.\nAbstract: To evaluate the effects of a therapeutic gastrointestinal diet on the apparent digestibility coefficients (ADCs), metabolizable energy (ME), and palatability of the diet, fermentative metabolites, and fecal microbiome of dogs. Sixteen 1-year-old healthy Beagles were used. All animals consumed a control diet for healthy adult dogs for 20 days. On day 21, 8 dogs changed to a therapeutic gastrointestinal diet (test diet), and 8 dogs continued receiving the control diet for 35 days. Fresh feces were collected on days 0, 3, 15, and 30 after changing to the test diet for pH, fermentative metabolites, and microbiota analysis. Feces were collected for ADCs and ME analysis of the diets (days 31 through 35). The palatability of the control and test diets was compared at the end of the study. The test diet presented greater ADCs of nutrients and ME and resulted in lower fecal pH and greater fecal concentrations of ammonia, total biogenic amines, total short-chain fatty acids, and butyrate. β-Diversity analysis revealed distinct fecal microbiome profiles between the diets on days 3, 15, and 30, with a greater abundance of Turicibacter and Faecalibacterium and lower Streptococcus in the test group. Dogs preferred the test to the control diet in the palatability test. The test diet presented high ADCs of nutrients, high palatability, and beneficially modulated the fecal microbiome and fermentative metabolites of dogs. Providing a highly digestible and palatable diet with functional ingredients may contribute to the treatment of gastrointestinal disorders of dogs.\n\nID: 42433265\nTitle: Real-World Efficacy and Safety of TACE Combined with Lenvatinib and PD-1 Inhibitor in Conversion Therapy for Unresectable Hepatocellular Carcinoma (GUIDANCE007): A Multicenter Retrospective Study.\nAbstract: Transarterial chemoembolization (TACE) combined with lenvatinib has demonstrated efficacy for unresectable hepatocellular carcinoma (HCC). However, real-world evidence on the additional benefit of PD-1 inhibitors in conversion therapy remains limited. This study aimed to investigate the efficacy and safety of triple therapy (TACE, lenvatinib, and PD-1 inhibitors) versus dual therapy (TACE and lenvatinib) in conversion therapy for initially unresectable HCC. This multicenter study was conducted in 20 Chinese tertiary hospitals. Patients received either triple therapy (TLP group, n = 289) or dual therapy (TL group, n = 132). Inverse probability of treatment weighting (IPTW) was used to control for confounding. Multivariate models compared overall survival (OS) and progression-free survival (PFS). From January 2019 to June 2023, 421 consecutive patients were enrolled. After IPTW adjustment, baseline characteristics were well balanced. The TLP group showed superior efficacy: objective response rate 55.1% versus 34.7% (p < 0.001), complete response rate 24.9% versus 14.9% (p = 0.010), and conversion surgery rate 35.5% versus 15.7% (p < 0.001). Median OS was prolonged (31.67 vs. 25.00 months; adjusted HR 0.60, 95% CI: 0.42-0.85, p = 0.001) and median PFS extended (16.47 vs. 12.00 months; adjusted HR 0.65, 95% CI: 0.47-0.93, p = 0.008). Sensitivity analyses including propensity score matching (HR 0.61), landmark analysis (HR 0.64), and time-varying covariate analysis (HR 0.58) confirmed the findings. E-value analysis (2.72) suggested unmeasured confounding alone is unlikely to explain the benefit. Treatment effects were consistent across subgroups. Grade 3-4 adverse events were similar (35.6% vs. 36.4%, p = 0.885), though immune-related adverse events were more frequent in the TLP group. Adding PD-1 inhibitors to TACE plus lenvatinib was associated with improved tumor response, prolonged survival, and higher conversion surgery rates, with an acceptable safety profile. Given the heterogeneity of PD-1 inhibitors and inherent limitations of retrospective design, these findings should be considered hypothesis generating and require verification in prospective randomized controlled trials. Liver cancer is one of the deadliest cancers worldwide. When liver cancer cannot be removed by surgery, doctors use treatments to shrink tumors, so surgery may become possible later. This is called “conversion therapy.” We studied 421 patients from 20 hospitals in China whose liver cancer could not be surgically removed at first. One group received two treatments: TACE (a procedure that blocks blood flow to tumors while delivering chemotherapy directly to them) plus lenvatinib (a pill that stops tumor blood vessel growth). The other group received these same treatments plus a PD-1 inhibitor, which helps the body’s immune system fight cancer. The group receiving all three treatments had better results. More patients saw their tumors shrink (55% versus 35%), and more were able to have surgery to remove their cancer (35% versus 16%). Patients receiving the three-treatment combination also lived longer, about 32 months compared to 25 months. Side effects were similar between groups. The most common included tiredness, changes in liver function tests, and decreased appetite. These findings suggest that adding immune therapy may help more patients with advanced liver cancer live longer and have a better chance of curative surgery. However, this was not a randomized trial, so more research is needed to confirm these results.\n\nID: 42424078\nTitle: Sex Differences in Long-Term Overall and Cause-Specific Mortality in Patients With Cirrhosis.\nAbstract: Evidence on sex differences in the natural history of cirrhosis and cause-specific mortality remains limited. To compare long-term all-cause and cause-specific mortality between male and female patients with cirrhosis. This population-based retrospective cohort study included hospitalized adults with cirrhosis identified from the California Department of Healthcare Access and Information database from January 2005 to December 2019. Propensity score matching (PSM) was used to balance baseline characteristics between male and female patients. Data were analyzed from August to December 2025. Sex (females compared with males). Ten-year all-cause and cause-specific (liver-related [hepatocellular carcinoma (HCC) and non-HCC], non-liver-related [cardiovascular and other]) mortality were assessed. Hazard ratios (HRs) of all-cause death were estimated using Cox models, and subdistribution hazard ratios (sHRs) of cause-specific death and receipt of liver transplantation (LT) were estimated using Fine-Gray competing risk models, stratified by age, race, ethnicity, social deprivation level, cirrhosis cause, and cirrhosis severity. Among 316 957 patients with cirrhosis (124 228 females [39.2%]; mean [SD] age, 61.4 [14.4] years; 192 729 males [60.8%]; mean [SD] age, 58.8 [13.1] years), PSM yielded 110 044 male-female pairs with balanced characteristics. Compared with males, females had lower estimated 10-year cumulative all-cause mortality (51 703 patients [58.2%] vs 53 310 patients [59.8%]), cardiovascular mortality (9215 patients [10.5%] vs 10 531 patients [11.9%]), and HCC-related mortality (3255 patients [3.6%] vs 4745 patients [5.4%]), but higher non-HCC liver-related mortality (18 572 patients [20.9%] vs 16 993 patients [19.0%]). In Cox models, females had a lower hazard of all-cause death (HR, 0.94; 95% CI, 0.93-0.96). In Fine-Gray models, females had lower hazards of cardiovascular-related (sHR, 0.86; 95% CI, 0.84-0.89) and HCC-related (sHR, 0.68; 95% CI, 0.65-0.71) death, but a higher hazard of non-HCC liver-related death (sHR, 1.09; 95% CI, 1.07-1.12). Stratified analyses suggested that females younger than 50 years (sHR, 1.06; 95% CI, 1.02-1.11) and those with alcohol-associated cirrhosis (sHR, 1.12; 95% CI, 1.08-1.17) had higher hazard of liver-related mortality, and females were less likely to undergo LT (sHR, 0.77; 95% CI, 0.66-0.89). In this cohort study of patients with cirrhosis, males had slightly higher all-cause mortality largely due to higher cardiovascular and HCC-related mortality, while females had higher non-HCC liver-related mortality; females younger than 50 years and those with alcohol-associated cirrhosis had higher liver-related mortality but lower rates of LT. These sex disparities warrant specific consideration in future guidelines for disease monitoring and transplant allocation.\n\nID: 42420258\nTitle: L-2-Hydroxyglutarate sensitizes ferroptosis through ATF3/CHAC1-mediated glutathione degradation in hepatocellular carcinoma.\nAbstract: Ferroptosis is an iron-dependent form of regulated cell death driven by lipid peroxidation and glutathione (GSH) depletion and represents a therapeutic vulnerability in hepatocellular carcinoma (HCC). While canonical ferroptosis regulation centers on cystine uptake and GPX4-mediated GSH utilization, the endogenous metabolic pathways governing ferroptosis sensitivity in liver tumors remain incompletely understood. Here, using a metabolic-scale CRISPR activation screen integrated with transcriptomic and metabolomic analyses, we identify L-2-hydroxyglutarate dehydrogenase (L2HGDH) as a potent antagonist of ferroptosis in HCC. We demonstrate that L2HGDH is frequently suppressed in liver tumors, leading to pathological accumulation of its substrate L-2-hydroxyglutarate (L2HG). Elevated L2HG sensitizes HCC cells to ferroptosis both in vitro and in vivo. Mechanistically, L2HG acts as a metabolic-epigenetic regulator that inhibits 2-oxoglutarate-dependent dioxygenases, induces histone hypermethylation, and remodels chromatin accessibility to activate an ATF3-dependent transcriptional program. This program induces the glutathione-degrading enzyme CHAC1, thereby accelerating GSH degradation to 5-oxoproline and disrupting redox homeostasis. Notably, L2HG-induced ferroptosis occurs independently of impaired cystine uptake, transsulfuration pathway activity, or increased GPX4-mediated GSH utilization, revealing a non-canonical ferroptosis mechanism driven by enhanced GSH catabolism. Consistent with these findings, genetic targeting of L2HGDH suppresses tumor growth, elevates L2HG levels, enhances GSH degradation, and promotes ferroptosis in HCC xenograft models. Collectively, our study identifies the L2HGDH-L2HG axis as a previously unrecognized metabolic checkpoint controlling ferroptosis sensitivity in liver cancer and uncovers glutathione degradation as a therapeutically exploitable vulnerability for ferroptosis-based treatment strategies in HCC.\n\nID: 42411358\nTitle: Lipidomic and Transcriptomic Insights into Hepatic Lipid Remodeling Induced by Peony Seed Oil.\nAbstract: Peony seed oil (PSO), rich in unsaturated fatty acids, especially α-linolenic acid, may influence hepatic lipid metabolism, but its mechanisms remain unclear. We evaluated the effects of PSO in high-fat diet-fed rats using biochemical assays, liver histology, hepatic lipidomics, transcriptomics, and targeted validation. PSO improved serum lipid profiles, reduced hepatic cholesterol and triglyceride levels, and alleviated steatosis. Lipidomics revealed extensive remodeling of hepatic lipid subclasses, with differential lipids enriched in polyunsaturated fatty acid (PUFA)-containing species. Integrated multiomics analysis showed coordinated changes in PUFA-containing phospholipids and fatty acid metabolism-related transcripts, including Fads1, Fads2, Ppara, Elovl5, and Cpt1a. Cross-omics correlations suggested adaptive regulation of endogenous PUFA metabolism rather than simple dietary lipid incorporation. Validation confirmed increased hepatic expression of Fads1, Fads2, and Ppara. These findings indicate that PSO improves hepatic lipid homeostasis by coordinating lipid composition and metabolic regulatory pathways.\n\nID: 42410764\nTitle: Association between hemoglobin glycation index and new-onset diabetes mellitus in individuals with chronic liver disease: Findings from a prospective cohort study using CHARLS data.\nAbstract: The hemoglobin glycation index (HGI), which measures the difference between observed and predicted glycated hemoglobin, is strongly associated with diabetic complications. However, its relationship with new-onset diabetes in patients with chronic liver disease (CLD) remains unexplored. This study aimed to investigate this association using data from the China Health and Retirement Longitudinal Study database. This study included 329 participants aged ≥45 years with CLD from the China Health and Retirement Longitudinal Study database. HGI was calculated as glycated hemoglobin - (0.013 × fasting plasma glucose + 4.804). Based on baseline HGI levels, participants were categorized into 3 groups (Q1-Q3). The primary endpoint was the occurrence of new-onset diabetes mellitus events. The Kaplan-Meier curves, multivariable Cox proportional hazards models, and restricted cubic spline analysis were applied to explore the association between baseline HGI levels and the risk of diabetes mellitus incidence among individuals with CLD. In the adjusted multivariable Cox regression analysis, HGI was significantly associated with a 53% increased risk of diabetes (hazard ratio = 1.53, 95% confidence interval: 1.17-1.99, P = .002). The Kaplan-Meier curve analysis revealed a significant difference in the occurrence of diabetes mellitus among the HGI groups. Significant risk thresholds were identified at HGI = -0.94, beyond which diabetes mellitus risk increased substantially. Stratified and interaction analyses confirmed the stability of this association. An increase in baseline HGI levels was significantly associated with the risk of diabetes mellitus in individuals with CLD. HGI can be used as a potential indicator for predicting the long-term risk of diabetes incidence in such patients.\n\nID: 42409346\nTitle: Astragalin from Morus alba L. ameliorates high-fat diet-induced obesity-related metabolic disturbances in mice and is associated with hepatic AMPK/PI3K/AKT signaling.\nAbstract: Morus alba L. (M. alba) also known as white mulberry is recognized in traditional Chinese medicine (TCM) and Ayurveda as a functional food and nutraceutical supplement for treating conditions such as hypertension, diabetes, and obesity. In TCM, mulberry leaves are specifically described as enhancing hepatic lipid metabolism, promoting lipid excretion to support obesity treatment. This study aimed to investigate the anti-obesity potential of M. alba leaf extract and its flavonoid component, astragalin (ASG), using a high-fat diet (HFD)-induced obese mouse model, and to elucidate the underlying molecular mechanisms. HFD-fed mice were treated with M. alba aqueous extract or ASG using a curative treatment approach. Body weight, glucose tolerance, insulin sensitivity, serum lipid profiles, hepatic steatosis, and inflammatory cytokines were assessed. Systemic and hepatic inflammation was measured by enzyme-linked immunosorbent assay (ELISA), while glucose transporter (GLUT1 and GLUT2) transcripts and protein levels were measured by RT-PCR and Western blotting, respectively. Molecular interactions were evaluated using cellular thermal shift assay (CETSA), drug affinity responsive target stability (DARTS), and molecular docking analyses, while AMP-activated protein kinase (AMPK), phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT), calcium/calmodulin-dependent protein kinase kinase 2 (CaMKK2) and liver kinase B1 (LKB1) phosphorylation was also assessed by Western blotting. Pharmacologic inhibition with Compound C was performed to confirm AMPK involvement. Treatment with M. alba extract significantly reduced body weight gain, improved serum lipid profiles, and attenuated hepatic lipid accumulation in obese mice. Phytochemical analysis identified ASG as a major bioactive constituent. ASG recapitulated several beneficial effects of the extract, including improvements in body weight gain, glucose tolerance, insulin sensitivity, hepatic lipid burden, and inflammatory status. ASG reduced systemic and hepatic levels of pro-inflammatory cytokines and modulated hepatic and intestinal GLUT1/2 transcripts and protein levels. Mechanistically, ASG showed evidence of AMPK engagement in CETSA, DARTS, and docking analyses, and was associated with increased hepatic AMPK and PI3K/AKT phosphorylation. Co-administration of Compound C attenuated several metabolic benefits of ASG, supporting AMPK involvement. ASG ameliorates obesity-related metabolic abnormalities in HFD-fed mice and is associated with AMPK engagement and increased hepatic AMPK/PI3K/AKT phosphorylation. These findings support ASG as a promising natural lead compound for obesity-related metabolic dysfunction, although further studies are needed to define its direct target interaction and downstream signaling more conclusively.\n\nID: 42406127\nTitle: A non-enzymatic sensor based on rGO/Pt NPs/Fc-Tyr/POPD nanocomposite for hydrogen peroxide determination in liver cancer tissues.\nAbstract: Malignant tumors remain a major global health challenge, highlighting the need for rapid and sensitive analytical tools for investigating cancer-associated oxidative stress. In this study, we developed a non-enzymatic electrochemical hydrogen peroxide (H₂O₂) sensor based on a reduced graphene oxide/platinum nanoparticle/ferrocene-tyramine/poly(o-phenylenediamine) (rGO/Pt NPs/Fc-Tyr/POPD) nanocomposite. H₂O₂, although not a tumor-specific biomarker, is an important reactive oxygen species associated with oxidative stress in cancer-related systems. The proposed sensing platform integrates the high conductivity of rGO, the electrocatalytic activity of Pt NPs, the TSA-derived Fc-Tyr deposition strategy, and the anti-interference properties of POPD. The sensor exhibited two wide linear detection ranges (5.0 µM-570 µM and 570 µM-10.5 mM), a low detection limit of 1.18 µM, and a rapid response time of less than 5 s. In addition, the sensor demonstrated satisfactory selectivity, reproducibility, and stability. Compared to previously reported rGO/Pt-based H₂O₂ sensors, the present platform introduces a TSA-derived Fc-Tyr deposition strategy to facilitate interfacial electron transfer and increase the density of redox-active species. The sensor was successfully applied to monitoring H₂O₂ changes in cultured cancer cells and ex vivo tumor tissue-derived samples under chemically stimulated oxidative conditions. These findings suggest that the proposed system may provide a useful tool for investigating oxidative-stress-associated biological processes and electrochemical H₂O₂ determination.\n\nID: 42401471\nTitle: Precise diagnosis of hepatocellular carcinoma and acute kidney injury through near-infrared imaging utilizing a fluorescence probe for monitoring α-l-fucosidase.\nAbstract: Herein, hepatocellular carcinoma (HCC) and acute kidney injury (AKI) were accomplished using α-l-fucosidase (AFU)-responsive fluorescent probe, HD-AFU, which incorporates the canonical AFU recognition moiety and a structurally optimized hemicyanine-thioxanthene signaling unit. In comparison with recently reported probes, HD-AFU demonstrated robust and reliable performance in monitoring AFU activity across HCC and AKI models. This probe enabled mitochondrial-targeted intracellular imaging to track AFU dynamics during progression and therapeutic intervention. In the orthotopic transplanted tumor mouse model, HD-AFU exhibited consistent capabilities for visualizing HCC status. To validate the accuracy of the probe in detecting AFU in AKI, we established four AKI models, including cisplatin-induced, gentamicin-induced, hyperuricemic nephropathy, and diabetic nephropathy models. The accurate establishment of these four models holds significant importance for subsequent fluorescence imaging studies. Additionally, we employed losartan and metformin to treat hyperuricemic nephropathy and diabetic nephropathy, respectively, and utilized the probe to achieve the screening and validation of therapeutic drugs. Furthermore, in a long-term induced HCC and AKI model validated by serum indices and histopathological assessment, HD-AFU successfully visualized the diagnostic and therapy process. These presented herein offer valuable insights for the development of effective diagnostic strategies.\n\nID: 42400345\nTitle: Nephronophthisis: Current clinical spectrum and molecular pathogenesis.\nAbstract: Nephronophthisis (NPH) is a ciliopathy primarily affecting renal tubules and interstitial tissue, ultimately progressing to end-stage kidney disease (ESKD). The clinical spectrum of NPH is broad and can be classified according to the age at onset into infantile, juvenile, adolescent, and late-onset forms. Histopathologically, NPH is characterized by corticomedullary cysts, tubular atrophy, interstitial fibrosis, and cystic dilatation of distal tubules. The kidneys may appear normal in early stages but gradually shrink with disease progression. More than 20 causative genes have been identified, with NPHP1 being the most common. These genes encode proteins that localize predominantly to the ciliary transition zone and basal body, where they regulate ciliary structure and signaling. Loss of ciliary function disrupts epithelial polarity, intracellular trafficking, and signal transduction, leading to tubular injury and fibrosis. When extrarenal organs such as the retina, liver, or central nervous system are affected, the condition is defined as nephronophthisis-related ciliopathies (NPH-RC). This review summarizes the current understanding of NPH classification, clinical features, and molecular mechanisms. Here, we highlighted recent advances in genetic discoveries, pathogenic signaling pathways, and therapeutic strategies, including gene therapy and targeted molecular interventions.\n\nID: 42399086\nTitle: Glucagon-like peptide-1 receptor agonists versus dipeptidyl peptidase-4 inhibitors after liver resection for hepatocellular carcinoma in patients with type 2 diabetes: a target trial emulation study.\nAbstract: Recurrence after curative-intent resection remains common in hepatocellular carcinoma (HCC), and whether postoperative incretin-based treatment choice influences outcomes in patients with type 2 diabetes (T2D) is unclear. To determine whether postoperative initiation of glucagon-like peptide-1 receptor agonists (GLP-1RAs), compared with dipeptidyl peptidase-4 inhibitors (DPP-4is), is associated with improved recurrence-free and overall survival after curative-intent resection for HCC. Active-comparator, new-user target trial emulation using electronic medical records from 36 hospitals across China from 2014 to 2023, with follow-up through 1 October 2025. Eligible adults had histologically confirmed HCC and T2D, underwent R0 resection and initiated a GLP-1RA or DPP-4i within postoperative days 0 to 90. Time zero was the first qualifying prescription or order date. The primary estimand was intention-to-treat; a prespecified per-protocol analysis assessed sustained adherence. The primary outcome was recurrence-free survival (RFS), treating death without recurrence as a competing event; overall survival (OS) was secondary. The study was registered with the Chinese Clinical Trial Registry (ChiCTR2600118495). Among 42 855 patients with HCC and T2D who underwent liver resection, 1249 were included in the final analytical cohort, including 723 DPP-4i initiators and 526 GLP-1RA initiators; median follow-up was 50.8 months. In weighted intention-to-treat analyses, GLP-1RA versus DPP-4i initiation was associated with longer RFS (cause-specific HR 0.80, 95% CI 0.67 to 0.96; p=0.016) and OS (HR 0.58, 95% CI 0.47 to 0.71; p<0.001). Per-protocol analyses were directionally consistent. Postoperative GLP-1RA initiation, compared with DPP-4i initiation, was associated with delayed recurrence and longer OS; prospective confirmation is warranted.

While large-scale proteomics improves HF prediction in general populations, its incremental predictive value beyond standard clinical models in MASLD remains unexplored. To identify plasma protein biomarkers for incident HF in MASLD and evaluate the predictive utility of integrating these signatures with the predicting risk of cardiovascular disease events (PREVENT) clinical model. We prospectively analyzed 17,091 individuals with MASLD at baseline. Multivariable and LASSO-Cox regressions were applied to 2911 plasma proteins to identify optimal predictors. Predictive discrimination and reclassification were assessed using Harrell's C-index, time-dependent area under the curve (AUC), net reclassification improvement (NRI), integrated discrimination improvement (IDI), and decision curve analysis (DCA). Over a median follow-up of 13.56 years, 953 incident HF events occurred. Integrating the PREVENT model with a 37-protein panel substantially improved predictive discrimination (C-index 0.805 vs. 0.723; ΔC-index 0.082, 95%CI: 0.064-0.100). Moreover, a parsimonious model containing only 5 proteins (NT-proBNP, WFDC2, LTBP2, BCAN, HAVCR1) delivered a meaningful incremental improvement over the PREVENT baseline (C-index 0.769 vs. 0.723; ΔC-index 0.046, 95%CI: 0.027-0.064). Pathway analyses indicated these proteins associating with systemic inflammation and extracellular matrix remodeling. Large-scale proteomics significantly enhances HF risk prediction in MASLD, providing a robust tool for identifying high-risk individuals who may benefit from intensive clinical monitoring and preventive strategies.\n\nID: 42388975\nTitle: H2S-mediated protein S-sulfhydration: a novel regulatory module in lipid metabolism.\nAbstract: H2S-mediated protein S-sulfhydration is an emerging post-translational modification that regulates key biological processes via regulating enzyme activities, controlling protein-protein interactions, and modulating signal transduction. Lipid metabolism represents an important target of S-sulfhydration-mediated regulation, which fine-tunes lipid metabolic networks including fatty acid turnover, triglyceride metabolism, and cholesterol homeostasis. This review aims to systematically summarize current knowledge on the regulation of lipid metabolism with a focus on S-sulfhydration, and highlight novel molecular targets identified in recent research. By integrating emerging evidence, we demonstrate how S-sulfhydration acts as a regulatory module linking redox signaling and lipid homeostasis, which may be leveraged therapeutically to treat lipid-associated disorders, either using H2S donors or sulfhydrated protein-targeted medications.\n\nID: 42386968\nTitle: N4-Acetylcytidine enhances synthetic mRNA translation yield and fidelity.\nAbstract: Synthetic mRNA therapeutics offer a versatile platform for treating diverse conditions, including cancer and infectious diseases. For delivery into cells, these mRNAs are encapsulated in lipid nanoparticles and commonly incorporate modified ribonucleotides to improve stability, enhance translation and mitigate immune recognition1. N1-Methylpseudouridine (m1Ψ) has become the industry standard for synthetic mRNAs owing to its effectiveness in promoting translation and reducing immunogenicity2. However, recent studies have shown that m1Ψ can compromise translational fidelity, leading to errors such as premature termination and ribosomal frameshifting3-5. Here we reveal N4-acetylcytidine (ac4C) as a functionally distinct alternative to m1Ψ. Across cultured cell lines, primary human monocyte-derived dendritic cells and mouse liver, ac4C suppressed inflammatory responses as effectively as m1Ψ while driving higher protein yields. Single-molecule imaging of translation revealed broadly similar ribosome densities per mRNA for ac4C-modified and m1Ψ-modified transcripts. However, translation elongation with m1Ψ-modified mRNA was nearly twofold slower than with ac4C, which resulted in reduced protein output and increased ribosome collisions that further limited protein production through the engagement of quality-control pathways and +1 frameshifting. These findings underscore the importance of context in designing therapeutic mRNAs and position the translation elongation rate as a key determinant of the efficacy of modified ribonucleotides.\n\nID: 42381008\nTitle: CTSS regulates macrophage lipid metabolic reprogramming and white matter repair after intracerebral hemorrhage.\nAbstract: Intracerebral hemorrhage (ICH) causes secondary white matter injury, which contributes substantially to long-term neurological disability. Although macrophages accumulate in the perihematomal region and participate in tissue remodeling after ICH, the molecular programs that link macrophage responses to white matter repair remain poorly understood, and no current strategies specifically target macrophage‑mediated white matter restoration. Cathepsin S (CTSS), a lysosomal cysteine protease involved in immune regulation and tissue remodeling, is strongly induced after brain injury; however, its role in post‑ICH white matter pathology has not been defined. A collagenase-induced mouse model of intracerebral hemorrhage (ICH) was established, followed by pharmacological inhibition of Cathepsin S (CTSS) using LY3000328. Single-cell RNA sequencing was performed on perihematomal tissues from Vehicle- and CTSS inhibitor-treated mice to explore CTSS-responsive cell populations and transcriptional programs. Macrophage lipid handling was assessed using flow cytometry, immunofluorescence, and fluorescent myelin debris-based uptake and lipid-transfer assays. A bone marrow-derived macrophage (BMDM)-oligodendrocyte precursor cell (OPC) co-culture system was used to determine whether CTSS inhibition alters macrophage-derived lipid support for OPC differentiation. The LXR agonist GW3965 was applied as a rescue intervention. White matter repair and neurological recovery were evaluated by myelin-associated protein analysis, immunofluorescence, behavioral testing, and transmission electron microscopy. Single-cell analysis identified infiltrating macrophages, particularly adaptive lipid-associated macrophages (aLAMs), as a major CTSS-expressing population after ICH, displaying a transcriptional state related to lipid metabolism and tissue repair. CTSS inhibition attenuated this lipid-associated macrophage program and reduced ApoE, ABCA1, and ABCG1 expression. Mechanistically, CTSS inhibition reduced Npc1/Npc2 expression and disrupted lysosomal cholesterol trafficking, leading to lysosomal cholesterol retention. These changes suggest impaired Npc1/Npc2-associated cholesterol mobilization and attenuation of the LXR-associated macrophage lipid efflux program. In BMDM-OPC co-cultures, CTSS inhibition reduced the transfer of fluorescent macrophage-processed myelin-derived lipids to OPCs and limited OPC differentiation, whereas GW3965 partially restored Npc1/Npc2 expression, macrophage-derived lipid support, and OPC differentiation. Consistently, in vivo CTSS inhibition reduced MBP expression and MBP⁺ axonal wrapping, increased g-ratio values, aggravated myelin ultrastructural abnormalities, and delayed neurological recovery after ICH. CTSS in macrophages supports white matter repair after ICH by maintaining lysosomal cholesterol trafficking and macrophage lipid efflux. CTSS inhibition limits macrophage-derived lipid support for OPCs and impairs remyelination, whereas LXR activation partially restores these reparative responses.\n\nID: 42380122\nTitle: Genetically modulating the RNA-binding protein Regnase-1 reveals its critical role in regulatory T cell homeostasis and function in vivo.\nAbstract: Regnase-1 is a CCCH-type RNA-binding protein that constantly degrades mRNA species via its ribonuclease domain to maintain immune quiescence. But how and by what mechanisms Regnase-1 regulates Foxp3+ Tregs remains poorly studied. Here, we generated a conditional knock-in strain in which a degradation-resistant Regnase-1 mutant (R111A) was selectively expressed in Foxp3+ Tregs as a transgene (Foxp3YFP-CreLSL-R111Afl/fl) to investigate the roles of Regnase-1 in Tregs. We found that all male Foxp3YFP-CreLSL-R111Afl/fl mice died of fatal autoimmune diseases by 4 weeks of age, which was accompanied by massive activation of T effector cells in vivo. We also found that the Foxp3+ Tregs in male Foxp3YFP-CreLSL-R111Afl/fl mice were progressively depleted in the periphery. Further analyses showed that the Foxp3+ Tregs expressing the R111A mutant displayed an intrinsic survival defect and that wild-type Foxp3+ Tregs adoptively transferred into young Foxp3YFP-CreLSL-R111Afl/fl mice could rescue the lethal autoimmune phenotype. Mechanistically, we demonstrated that the Regnase-1 readily degraded Bcl2l1 mRNA (encoding Bcl-xL) via binding to the Bcl2l1 mRNA stem loop structure, thus preventing Bcl-xL expression in Tregs. Thus, Tregs expressing the R111A mutant exhibited not only survival defects but also failure to respond to IL-2, resulting in their eventual demise in vivo. Together, our studies suggest that Regnase-1 can have a profound impact on Foxp3+ Tregs and that modulating Regnase-1 in Tregs may have important therapeutic implications.\n\nID: 42375567\nTitle: Resveratrol Attenuates Obesity by Inducing GDF15 Expression via the p38-ATF3 Signaling Pathway.\nAbstract: Resveratrol, a natural polyphenol, has been widely studied for its potential health benefits in obesity treatment, but its molecular mechanism remains elusive. This study investigates the molecular mechanisms by which resveratrol promotes the expression and secretion of Growth Differentiation Factor 15 (GDF15), a key regulator of energy homeostasis. Using both murine embryonic fibroblasts (MEFs) and human HepG2 cells, resveratrol dose-dependently upregulates Gdf15 mRNA and protein expression, as well as increases GDF15 secretion. Transcriptome analysis and subsequent validation experiments revealed that Activating Transcription Factor 3 (ATF3) mediates the effect of resveratrol on GDF15 expression. Additionally, resveratrol-treated mice exhibited resistance to high-fat diet-induced obesity and increased plasma GDF15 levels. In vivo studies in mice further confirmed that resveratrol treatment elevates GDF15 levels in liver, kidney, and colon tissues, and enhances downstream ERK signaling in the brain. Collectively, these findings suggest that GDF15 plays a critical role in mediating the anti-obesity effects of resveratrol.\n\nID: 42375102\nTitle: Transcriptomic Analysis Reveals Multilayer Regulation Underlying Development and Pregnancy in the Malayan Pangolin.\nAbstract: The critically endangered Malayan pangolin (Manis javanica) exhibits distinctive physiological adaptations; nevertheless, its molecular mechanisms underlying development and reproduction remain inadequately characterized, thereby impeding effective conservation initiatives. In this study, we conducted a comprehensive transcriptomic analysis of six tissues (intestine, kidney, liver, lung, muscle, and spleen) derived from adult, fetal, and pregnant individuals. The fetal stage demonstrated the greatest abundance of stage-specific genes, which were predominantly enriched in developmental pathways such as epithelial organization and transmembrane signaling. Differential gene expression (DGE) analysis revealed that genes upregulated in adults were primarily associated with metabolic and immune functions, whereas those upregulated in fetuses were linked to developmental processes and cell cycle regulation. Co-expression network analysis identified critical hub genes, including GLDC in adults and NCAM1 in fetuses, that are implicated in stage-specific regulatory mechanisms. Additionally, extensive differential alternative splicing (DAS) events were observed, with exon skipping (SE) representing the most frequent splicing pattern. Integrative analyses suggested that DGE and DAS largely constitute independent regulatory layers; however, a subset of hub genes, such as OBSL1 and TNIP1, exhibited concurrent differential expression and splicing, indicating their potential central roles in coordinating developmental processes. This study presents a detailed transcriptomic atlas of Malayan pangolin development and pregnancy, providing candidate biomarker genes for evaluating reproductive health and developmental status, thereby informing future conservation strategies.\n\nID: 42374630\nTitle: Hypogin-derived N-cinnamoylated peptide as a promising green fungicide against peanut southern blight caused by Sclerotium rolfsii.\nAbstract: Peanut southern blight, caused by Sclerotium rolfsii, severely reduces yield and quality. The overuse of chemical fungicides accelerates resistance development and raises environmental concerns, highlighting the necessity for eco-friendly alternatives. Hypogin is an endogenous peanut peptide with broad-spectrum antifungal activity. This study aims to identify the active centers of hypogin and evaluate the antifungal activity and preliminary mechanisms of its derived peptides. Seven hypogin-derived peptides (series I) and two cinnamic acid conjugates (series II) were synthesized. Among these, II-1 (cinnamic-KSPY-NH2) demonstrated the highest in vitro activity against S. rolfsii, with a half-maximal effective concentration value of 257.93 mg/L. In vivo studies revealed that II-1 provided superior curative efficacy (66.47%) against peanut southern blight, surpassing the commercial fungicide polyoxin (57.33%), and also promoted root growth in peanuts. Both I-7 and II-1 exhibited low cytotoxicity toward human LO2 liver cells, with inhibition rates of 5.05% and 17.44%, respectively, at a concentration of 400 mg/L. Preliminary mechanistic investigations indicated that I-7 specifically targets the Vps34 signaling pathway in S. rolfsii. Hypogin-derived peptide II-1 exhibits significant antifungal activity and low toxicity, making it a promising candidate for a green fungicide in the management of peanut southern blight. © 2026 Society of Chemical Industry.\n\nID: 42371494\nTitle: Preoperative Systemic Pan-Immune-Inflammation Value Predicts Posthepatectomy Liver Failure After Laparoscopic Resection for Hepatocellular Carcinoma: A Retrospective Cohort Study.\nAbstract: Post-hepatectomy liver failure (PHLF) remains a major cause of morbidity after liver resection for hepatocellular carcinoma (HCC). Routine blood-count-based inflammatory indices may complement established liver reserve assessments. This study evaluated whether preoperative systemic pan-immune-inflammation value (S-PIV) predicts PHLF after conventional laparoscopic hepatectomy for HCC. We conducted a single-center retrospective cohort study of consecutive patients who completed conventional laparoscopic hepatectomy for liver tumors between January 2017 and December 2025. Eligible patients had pathologically confirmed HCC and complete preoperative laboratory data within 7 days before surgery. Planned open hepatectomy, conversion to open surgery, and robotic-assisted hepatectomy were outside the predefined cohort scope. S-PIV was calculated as neutrophil count × monocyte count × platelet count / lymphocyte count. The primary outcome was ISGLS-defined PHLF, analyzed as any-grade PHLF versus no PHLF. Discrimination was assessed using ROC analysis, dose-response using restricted cubic splines, and clinical utility using decision curve analysis. Among 582 screened patients, 356 were included; 68 (19.1%) developed PHLF. Preoperative S-PIV showed good discrimination for PHLF (AUC 0.873). The Youden index identified an optimal cut-off of 455.4, with sensitivity 0.726 and specificity 0.908. S-PIV showed higher AUCs than NLR (0.831) and PLR (0.848). Higher S-PIV was associated with PHLF in univariable analysis (per 100 units: OR 1.12, 95% CI 1.06-1.45; P<0.001) and remained independently associated after sequential adjustment for demographics/comorbidities, liver functional reserve, and tumor/operative factors (Model 3 per 100 units: OR 1.06, 95% CI 1.03-1.13; P<0.001). Restricted cubic splines showed a graded risk increase without evidence of nonlinearity, and decision curve analysis suggested net benefit across threshold probabilities of approximately 10%-70%. Preoperative S-PIV, derived from routine blood counts, may serve as a practical adjunct for PHLF risk stratification after conventional laparoscopic hepatectomy for HCC. External multicenter validation and calibration are urgently required before routine implementation. Liver surgery can help many patients with liver cancer, but some patients may have poor liver function after part of the liver is removed. This problem can slow recovery and may become serious. Doctors therefore need simple ways to identify patients who may need closer care before and after surgery. In this study, we reviewed people with this type of liver cancer who had laparoscopic liver surgery at our hospital. We tested whether information from a routine blood test before surgery could help estimate the chance of liver failure after surgery. This blood test reflects the balance between inflammation and immune status in the body. We found that patients with a higher inflammation-related blood score before surgery were more likely to develop liver failure after surgery. This score may help doctors discuss surgical risk with patients, plan perioperative care, and identify patients who may need closer monitoring after surgery. These findings are promising, but they come from one hospital. More studies from multiple hospitals are needed before this blood score can be used routinely in clinical practice. What do the terms mean? The terms used in this article are explained in plain language as follows. Hepatocellular carcinoma refers to the most common type of primary liver cancer. Laparoscopic liver surgery refers to liver surgery performed through small cuts in the abdomen using a camera and surgical instruments. Liver failure after surgery refers to a condition in which the remaining liver does not work well enough after part of the liver has been removed. A blood inflammation score is calculated from routine blood cell counts and reflects inflammation and immune status. Liver reserve refers to the ability of the liver to keep working after surgery. Closer monitoring means more careful observation and follow-up before and after surgery. Multicenter validation means testing the findings in patients from other hospitals to confirm whether the results are reliable.\n\nID: 42370768\nTitle: Idiopathic anaphylaxis and histamine dysregulation: Revisiting pathophysiologic assumptions.\nAbstract: Idiopathic anaphylaxis (IA) is a diagnosis of exclusion, and the etiology remains elusive. Research on immunoglobulin E (IgE)-mediated anaphylaxis has identified histamine as the immune system mediator, but dietary histamine's potential role in IA is often overlooked. For some individuals, excessive histamine may cause IA and mimic signs and symptoms of IgE-mediated anaphylaxis.1 This review provides an overview of IA and the potential role of histamine in symptom manifestation. It aims to enhance awareness and provide nurse practitioners with insights into the complexities of managing IA, emphasizing the importance of considering dietary factors in patient care and treatment strategies.\n\nID: 42367940\nTitle: FALCON: Closed-Loop Multi-Objective Optimization of Lipid Nanoparticles for Cell-Selective mRNA Delivery.\nAbstract: Efficient, cell type-selective delivery of genetic payloads remains a central challenge in the development of gene and cell therapies. Lipid nanoparticles (LNPs) offer a versatile delivery platform, but their optimization is hindered by reliance on brute-force screening methods that are laborious, resource-intensive, and focus on single targets. Here, we present FALCON (Framework for Active Learning-driven Compositional Optimization of Nanoparticles), a closed-loop pipeline that leverages iterative screening, surrogate modeling, and multi-objective optimization to accelerate LNP compositional design. In B cell-targeted validation experiments, FALCON-optimized LNPs achieved a 1.8-fold increase in splenic B cell transfection in vivo compared with reference compositions. When optimized for selectivity, FALCON LNPs displayed an 84-fold improvement in selective transfection of splenic B cells over off-target liver populations and enabled spleen-tropic behavior across factorial panels of varying ionizable and helper lipid chemistries. In vaccine studies, these LNPs induced higher IgG2c antibody titers and a more Th1-biased immune profile. FALCON was also deployed to optimize LNPs for myeloid cell-selective delivery, achieving enhanced in vivo selectivity following systemic administration both across and within spleen and liver compartments. Our results establish FALCON as a useful tool for data-driven design of LNP compositions for precision gene delivery.\n\nID: 42367759\nTitle: Establishment of a laboratory mouse model to study Borrelia miyamotoi infection and disease.\nAbstract: Borrelia miyamotoi is an emerging relapsing fever spirochete transmitted by Ixodes spp. ticks that serve as vectors for other human pathogens, including the agents of Lyme disease. To date, an animal model to study tick-borne B. miyamotoi infection and pathology has not been reported. Here, we describe the development of a laboratory mouse model of infection using clinical isolate CT14D4 derived from the blood of a Connecticut resident with disseminated Lyme disease. Genomic analysis revealed that the CT14D4 genome was similar to other B. miyamotoi strains isolated from Ixodes scapularis ticks in the eastern United States. We show that CT14D4 can be propagated in mice by needle inoculation and through a tick-mouse infection cycle. Relapsing spirochetemia was observed in wild-type (WT), Myd88 -/-, and splenectomized mice, all of which eventually cleared the infections. In contrast, Rag1 -/- mice lacking B and T cells remain persistently bacteremic. WT mice that had cleared CT14D4 infection are resistant to reinfection with this B. miyamotoi strain. Spirochetes were visualized in several organs after perfusion fixation of infected Rag1 -/- mice, including the brain, with histopathology revealing extramedullary hematopoiesis and inflammatory infiltrates that were most pronounced in the liver. WT mice exhibited similar but milder pathology during periods of bacteremia. These studies provide a useful model to study hard-tick relapsing fever pathogenesis and disease.\n\nID: 42364637\nTitle: The effects of T-2 toxin on hepatic cytochrome P450 and carboxylesterase enzymes in mice: Evidence as changes in their expression, activity, and transcriptomic profiles.\nAbstract: T-2 toxin, a highly toxic trichothecene mycotoxin contaminating cereal grains, poses serious health threats. However, its specific effects on hepatic drug-metabolizing enzymes (DMEs) remain poorly characterized. This study aimed to investigate the impact of T-2 toxin on key cytochrome P450 (CYP) and carboxylesterase (CES) enzymes in mouse liver. Male C57BL/6 mice were randomly divided into control and T-2 toxin-treated groups, receiving either normal saline or T-2 toxin (0.2 mg/kg) by oral gavage daily for four weeks. Histopathological and ultrastructural alterations were assessed by hematoxylin and eosin staining and transmission electron microscopy. The activity, mRNA, and protein levels of target enzymes in liver tissues or AML12 cells were determined via enzymatic assays, quantitative real-time PCR (qRT-PCR), and western blotting. Transcriptomic profiling (RNA-seq) was performed to identify differentially expressed genes (DEGs) and enriched pathways. T-2 toxin exposure induced hepatocellular injury, including focal necrosis and mitochondrial damage. It significantly altered the activity and expression of multiple phase I DMEs, notably CYP1A2, CYP2B10, CYP3A11, and CES isoforms, at both transcriptional and protein levels. Transcriptomic analysis identified 277 DEGs, predominantly enriched in xenobiotic and drug metabolism pathways, including drug metabolism-cytochrome P450 and xenobiotic metabolic process. T-2 toxin induces hepatotoxicity and concurrently alters the expression and activity of key hepatic DMEs. These findings provide insight into T-2 toxin-induced disturbances in xenobiotic metabolism and may contribute to future studies on metabolic biomarkers and toxicological mechanisms.\n\nID: 42361946\nTitle: Dose- and time-dependent dissemination of viable Leishmania amazonensis following experimental footpad infection in mice.\nAbstract: Cutaneous leishmaniasis is typically characterized by localized skin lesions, but the extent to which Leishmania amazonensis disseminates beyond the primary site of infection remains incompletely defined. In this study, BALB/c mouse footpads were infected subcutaneously with L. amazonensis promastigotes at doses ranging from 105 to 108, and infection was evaluated over time up to 120 days. All infected groups developed local footpad infection, and amastigotes were detectable at the infection site early after challenge. Footpad swelling and parasite burden increased progressively, with more pronounced local lesion development observed at higher infective doses. At an infective dose of 1 × 106, viable parasites were recovered predominantly from the footpad and bone marrow, with only limited detection in the spleen at later time points. In contrast, infection with 1 × 108 promastigotes resulted in broader dissemination, with viable parasites detected in the bone marrow and spleen and, at later stages of infection, in the liver and peripheral blood. Parasite-specific IgG, IgG1, and IgG2a antibody responses were also higher in the 1 × 108 infection group than in the 1 × 106 group. These findings show that experimental L. amazonensis infection is not uniformly restricted to the skin and that viable parasite dissemination to non-cutaneous tissues is influenced by inoculum size and infection duration.\n\nID: 42360906\nTitle: In vitro evaluation of monoamine oxidase and acetylcholinesterase enzyme activities of Capparis cartilaginea Decne.\nAbstract: The genus Capparis is recognised for its neuroprotective potential; however, the biological activity of Capparis cartilaginea Decne. (C. cartilaginea) remains insufficiently explored. This study evaluated the in vitro inhibitory activity of the combined fractions of C. cartilaginea leaves and their isolated flavonoids against monoamine oxidase A (MAO-A) and B (MAO-B) using liver and brain mitochondrial preparations. The fractions inhibited both isoforms in a concentration-dependent manner, with the most pronounced MAO-B inhibition observed in liver mitochondria (97.9% at 2.0 mg/mL), exceeding the activity of the reference inhibitor deprenyl (91.8%). Among the isolated flavonoids, narcissin exhibited the strongest MAO-B inhibition (Ki = 0.34 ± 0.06 μmol/L), followed by rutin, manghaslin, and nicotiflorin. No significant acetylcholinesterase (AChE) inhibition was detected. These findings suggest that C. cartilaginea and its flavonoid constituents represent promising leads for the development of MAO-B-targeted neuroprotective agents.\n\nID: 42356741\nTitle: A CNN-MAMBA-Based Framework for Salient Bowel Sound Detection and Gastrointestinal Health Assessment.\nAbstract: With the rapid aging of the global population, constipation has become a major gastrointestinal concern among elderly individuals. Bowel sounds provide a non-invasive acoustic signal for assessing gastrointestinal function, but their automatic analysis remains challenging due to sparsity and non-stationarity. This study proposes a two-stage bowel sound analysis framework based on continuous abdominal recordings. First, a Convolutional Neural Network-MAMBA (CNN-MAMBA) model was used for salient bowel sound detection. Second, a patient-level constipation classification model was developed using multi-view spectral representations and a Convolutional Neural Network-Conformer-Multiple Instance Learning (CNN-Conformer-MIL) architecture. On a held-out test set, the detection model achieved an accuracy of 0.87, an F1-score of 0.78, and a ROC-AUC of 0.93. For patient-level classification under binary Bristol Stool Form Scale (BSFS) grouping, five-fold cross-validation yielded a mean accuracy of 0.665 and an F1-score of 0.755. All BSFS labels were annotated by clinical physicians and temporally aligned with bowel sound recording. Given the modest improvement and cross-validation variability, the patient-level results should be interpreted as preliminary feasibility evidence. These findings suggest that bowel sound analysis may serve as an auxiliary screening or longitudinal monitoring tool rather than a stand-alone diagnostic system.\n\nID: 42356402\nTitle: Preliminary Assessment of Red Beetroot Supplementation and Cultivar Effects in Low-Protein-Fed WKY Rats.\nAbstract: Background/Objectives: Red beetroot (Beta vulgaris L.) is recognized for its antioxidant, anti-inflammatory, and metabolic properties. This study evaluated the effects of two beetroot cultivars (Boldor and Wodan) on blood serum parameters, body composition, and organ weights in male WKY rats fed a low-protein diet (LPD, 8.8% protein). Methods: Five-week-old male rats were maintained on an LPD for 8 weeks and subsequently continued on the LPD diet supplemented with 4% dried beetroot for 45 days. The experimental diets included beetroot from the Boldor and Wodan cultivars, either treated or untreated with a plant growth stimulator during cultivation. Results: Foliar application of the selenium-based plant growth stimulator did not significantly increase selenium or other element concentrations in beet roots. Elemental analysis showed higher levels of Fe, Zn, Cu, Cr, Pb, As, Cd, and Sb in the Wodan group, while Boldor increased Cr, Pb, and As; Ni and Se remained unchanged. Beetroot supplementation significantly affected 14 of the 30 measured biochemical parameters, including biomarkers of liver function (ALT, ALP, total bilirubin, albumin, and total protein), renal function (uric acid), pancreatic activity (amylase and lipase), electrolyte balance (sodium, potassium, and chloride), mineral metabolism (calcium), inflammatory status (CRP), and nutritional metabolism (iron). Conversely, no significant effects were observed on lipid profile parameters or biomarkers of cardiac and skeletal muscle injury. Among the beetroot cultivars evaluated, Wodan exerted distinct effects relative to Boldor, resulting in higher circulating total bilirubin and potassium concentrations, alongside reduced uric acid and lipase levels in treated rats. Boldor supplementation significantly increased body weight gain and fat mass, with a trend toward higher lean mass, and increased kidney weight. Wodan did not significantly affect body weight but increased kidney and spleen mass. Feed intake was similar across groups. No changes in cardiovascular function were observed ex vivo. Conclusions: Beetroot supplementation modulated multiple metabolic and physiological biomarkers in rats fed a low-protein diet, with distinct cultivar-specific effects, underscoring the importance of cultivar selection for optimizing functional dietary interventions.\n\nID: 42351108\nTitle: A magnetic resonance imaging-guided drug delivery system for premetastatic niche theranostics and colorectal cancer liver metastasis intervention.\nAbstract: Colorectal cancer liver metastasis (CRLM) poses a major challenge in cancer theranostics, in which hepatic stellate cell (HSC) activation participates in fibrosis progression and colorectal cancer (CRC) cell recruitment, catalyzing the formation of fibrosis-concomitant premetastatic niche (PMN). Targeting the crosstalk between activated HSCs (aHSCs) and CRC cells, we develop a bioengineered, mesoporous superparamagnetic iron oxide nanoparticle (mSPIONP)-based theranostic nano-system (mSPIONP-Cur@eCM). Camouflaged with CXC chemokine receptor type 4 (CXCR4)-overexpressing CRC cytomembranes, this nano-system exhibits a dual PMN-targeting function, exerting a homologous recognition to CRC cells and anchors to aHSCs with a high secretion of stromal cell-derived factor-1 (SDF-1). Its mSPIONP-Cur core affords not only T2-weighted magnetic resonance imaging (MRI) but also curcumin (Cur) delivery, initiating liver fibrosis detection and metastasis foci delineation, simultaneously blocking the HSC-CRC cell crosstalk by amplifying Cur's therapeutic effect. Verified in fibrosis and CRLM models, mSPIONP-Cur@eCM exhibits great potential for suppressing the fibrosis-concomitant PMN and intervening the CRLM progression.\n\nID: 42344916\nTitle: Antibody-based regimens targeting PD-1/PD-L1 and VEGF/VEGFR in advanced or metastatic NSCLC: a meta-analysis of RCTs.\nAbstract: Antibody-based regimens targeting programmed cell death protein-1 (PD-1)/programmed death-ligand 1 (PD-L1) and vascular endothelial growth factor (VEGF)/vascular endothelial growth factor receptor (VEGFR) include conventional PD-1/PD-L1 inhibitors combined with anti-angiogenic monoclonal antibodies and PD-1/VEGF or PD-L1/VEGF bispecific antibodies, with or without chemotherapy. However, the clinical efficacy of these regimens in advanced or metastatic non-small cell lung cancer (NSCLC) remains unclear. This meta-analysis systematically evaluated their efficacy. PubMed, EMBASE, Web of Science, ClinicalTrials.gov, and the Cochrane Library were searched to identify relevant randomized controlled trials (RCTs) published up to February 2026. The main outcomes analyzed were progression-free survival (PFS) and overall survival (OS), with the hazard ratio (HR) and 95% confidence interval (95%CI) used for statistical analysis. The study protocol was registered on PROSPERO (CRD420251126421). Eleven RCTs were included in the analysis, with 4,426 participants. Antibody-based regimens targeting PD-1/PD-L1 and VEGF/VEGFR, with or without chemotherapy, were associated with better PFS (HR = 0.65, 95%CI: 0.57-0.75, p<0.001) and OS (HR = 0.79, 95%CI: 0.71-0.87, p<0.001) compared with the control regimen. For PFS, favorable subgroup estimates were observed in men (HR = 0.61), squamous histology (HR = 0.57), patients with liver metastases (HR = 0.49), those with higher PD-L1 expression (tumor proportion score (TPS)≥50%: HR = 0.65), those with epidermal growth factor receptor (EGFR) mutation (HR = 0.60). For OS, favorable subgroup estimates were observed in patients with Eastern Cooperative Oncology Group (ECOG) performance status (PS)=1 (HR = 0.80), men (HR = 0.80), smokers (HR = 0.82), those with liver metastases (HR = 0.57), those with PD-L1 TPS 1%-49% (HR = 0.67), and EGFR-mutant patients (HR = 0.80). Antibody-based regimens targeting PD-1/PD-L1 and VEGF/VEGFR improve prognosis in advanced or metastatic NSCLC, with potential variation in benefit across clinicopathological characteristics.\n\nID: 42344601\nTitle: A Critical Perspective on the Role of Thirdhand Smoke in Tumorigenesis: Initiator or Promoter.\nAbstract: Thirdhand smoke (THS), lingering tobacco residues on surfaces and in dust after smoking, has emerged as a growing public health concern. While the carcinogenic risks of first- and secondhand smoke are well established, the tumorigenic potential of THS remains inadequately understood. In this perspective, we systematically review the known THS-related compounds together with the existing biological findings to provide evidence on the carcinogenic potential of THS. We assess the role of THS in the context of the classic multistage model of tumorigenesis to address whether THS acts primarily as a tumor initiator, or as a promoter, or both. We also discuss methodological challenges in isolating the effects of THS on human health and the importance of animal models and outline emerging strategies for risk assessment, biomarker discovery, and precision prevention. This Perspective is the first to integrate chemical, toxicological, and mechanistic evidence to evaluate the carcinogenic potential of THS within the framework of the multistage model of tumorigenesis, offering a new conceptual foundation for understanding the role of THS in human cancer etiology, which is crucial for informing public health policies aimed at mitigating its impact.\n\nID: 42343527\nTitle: [TCM pathogenesis and acupuncture-moxibustion differentiation and treatment of Crohn's disease based on the \"liver-spleen-intestine\" axis].\nAbstract: To explore the TCM pathogenesis and acupuncture-moxibustion differentiation and treatment of Crohn's disease (CD) based on the \"liver-spleen-intestine\" axis. It is considered that liver depression with qi disorder, which triggers the imbalance between the spleen and intestine, is the initiating factor of CD. The key pivotal point lies in the failure of the spleen in transportation due to spleen deficiency, which generates dampness, restricts the liver, and stagnates the intestine.Intestinal disorders affecting the internal organs, and harming the qi of the liver and spleen, are the final stage. The treatment takes \"relieving liver stagnation-strengthening spleen function-regulating intestine\" as the principle, using acupuncture and moxibustion as the method, and achieves holistic treatment through core main acupoints-selection of acupoints based on syndrome differentiation-symptomatic selection of acupoints. The primary acupoints include Taichong (LR3), Qimen (LR14),Yinlingquan (SP9), Zusanli (ST36), Tianshu (ST25), and Shangjuxu (ST37), and modifications are made according to symptoms, which can smooth liver qi dispersion, strengthen spleen-stomach function, and harmonize bowel activity. The above treatment methods can improve the symptoms of CD patients and provide new ideas for the clinical prevention and treatment of CD in TCM. 基于“肝-脾-肠”轴探讨克罗恩病（CD）的中医病机规律及针灸辨治方案。肝郁气乱，引动脾肠失衡为CD之始动环节；脾虚失运，酿湿遏肝滞肠为CD关键枢纽；肠病及脏，反伤肝脾之气为CD终末环节。针灸治疗以“疏肝-健脾-调肠”为纲，以针刺、艾灸为法，通过核心主穴-辨证选穴-对症选穴实现整体论治。核心取穴以太冲、期门、阴陵泉、足三里、天枢、上巨虚为主，随证配穴，使肝气疏泄、脾胃健达、肠腑和顺，以期改善CD患者症状，为中医临床防治CD提供新思路。.\n\nID: 42341503\nTitle: Global and mitochondrial choline dehydrogenase contribute to goose fatty liver formation by differentially regulating energy metabolism, autophagy and oxidative stress related pathways.\nAbstract: The liver of geese has a strong ability to deposit fat and also has the ability to resist inflammation. Goose fatty liver represents a unique physiological model that exhibits no or low-level inflammation despite severe steatosis. Mitochondria and their proteins play a crucial role in the regulation of hepatic inflammation. However, it remains unclear whether choline dehydrogenase (CHDH), a mitochondrial protein, is involved in fat deposition and inflammation resistance in goose fatty liver formation. Here, we observed distinct expression patterns of mitochondrial CHDH (mCHDH) other than global CHDH (gCHDH) in goose versus mouse fatty livers, highlighting the unique role of mCHDH in goose fatty liver formation. Overexpression of gCHDH in goose primary hepatocytes led to increased cellular lipid accumulation, mitochondrial membrane potential (MMP) and respiratory chain complex II activity, alongside activation of immune response, apoptosis, cell adhesion, and lipid metabolism-related pathways. Moreover, overexpression studies in HepG2 cells revealed that both gCHDH and a mitochondrial targeting sequence-mutant CHDH (Δ1-38CHDH) elevated MMP, but they differentially regulated reactive oxygen species (ROS) level (Δ1-38CHDH slightly reduced intracellular ROS level) and the abundance of mitochondria-related proteins (gCHDH selectively increased tAMPK and decreased LC3B in mitochondrial lysates, whereas Δ1-38CHDH mainly reduced tAMPK and pAMPK in whole-cell lysates). Furthermore, transcriptome sequencing and mass spectrometry analyses revealed that CHDH may participate in processes such as immune response, ubiquitin-mediated degradation, autophagy, signal transduction and lipid metabolism. In summary, gCHDH and mCHDH contribute to the formation of goose fatty liver by affecting mitochondrial protein composition (AMPK, LC3B), mitochondrial function and related biological processes, though their effects exhibit certain differences. These findings provide new insights into the mechanism underlying the uniqueness of goose fatty liver.\n\nID: 42337761\nTitle: Triple primary synchronous liver cancer in one patient: the first case report and origin speculation through bioinformatics.\nAbstract: A diagnosis of multiple primary liver tumors is extremely rare. Preoperative diagnosis based on imaging findings is difficult. Moreover, the clinical benefits of treatment strategies for multiple liver cancers remain unclear. Here, we report a case of three synchronous primary liver tumors with three distinct pathological types-hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (ICC), and combined hepatocellular-cholangiocarcinoma (cHCC‑CCA)-in a single patient. Bioinformatics analysis supported at least two clonal origins, with cHCC‑CCA and ICC sharing a common lineage based on identical HBV integration sites. A 63-year-old female with a history of hepatitis B for several years presented with three lesions in hepatic segment VIII. Multiphase magnetic resonance imaging with gadolinium ethoxybenzyl diethylenetriaminepentaacetic acid revealed a diagnosis of multiple lesions, namely, cHCC‑CCA, with multiple intrahepatic metastases. The AFP level was normal, while the CA 19 - 9 level was mildly elevated (normal range ≤ 30.00 U/ml). Hepatectomy was performed, and postoperative assessment confirmed that the large lesion was cHCC‑CCA. However, the small lesions close to the large lesion were HCC and ICC. Gene testing revealed distinct mutational profiles among the three tumors. Similar gene mutations were detected in cHCC‑CCA and ICC. We also found that gene fragments of hepatitis B virus-C (HBV-C) were inserted into the genomes of ICC and cHCC‑CCA rather than that of HCC. The genomic integration site of HBV-C in cHCC‑CCA and ICC was the same. We report an extremely rare case of three synchronous primary liver tumors with three distinct pathological types (HCC, ICC, and cHCC‑CCA) in a single patient. Bioinformatics analysis supported at least two clonal origins, with cHCC‑CCA and ICC sharing a common lineage based on identical HBV integration sites. Hepatectomy represents a potential radical strategy for the treatment of multiple PLCs.\n\nID: 42335402\nTitle: Ultra-Radiostable Covalent Conformationally Interlocked Networks Enabling a Universal Radiometal-Labeling Platform for Cancer Radioembolization.\nAbstract: Transcatheter arterial embolization (TARE) has emerged as a highly effective locoregional treatment for advanced liver cancer, which represents a significant advancement in clinical practice. Nonetheless, the utilization of traditional radioactive microspheres in TARE is hindered by various material and technical challenges that necessitate resolution. Herein, we present, for the first time, well-designed and synthesized conjugated poly(imide dioxime) ligand-based microspheres (PID-Ms) with a remarkable radiometal coordinate covalent conformational interlocked network. PID-Ms can be radiolabeled with various radionuclides, including 177Lu, 90Y, 188Re, 68Ga, and 99mTc, can be achieved at low temperatures (40°C), and for diagnostic imaging and radiotherapy applications. The combined strategy of extended x-ray absorption fine structure spectroscopy (EXAFS), DFT calculations, and in vitro and in vivo radiostability experiments collectively confirmed that radiometal-PID complexes exhibit ultra-high radiostability. 177Lu-PID-Ms were employed to accurately predict normal organ shunts and radiotherapy in rat and rabbit VX2 orthotopic live tumor models, demonstrating their ultra-radiostability and remarkable anti-tumor efficacy. Furthermore, Radiometals-PID-Ms have an adjustable shelf life, enabling on-demand radiolabeling for drug preparation, achieving rapid 'on-demand' capability. This innovative approach has the potential to inspire the synthesis of numerous coordination polymeric materials for various applications in PET/SPECT-mediated radiopharmaceutical therapy, alpha-nucleophile-targeted radiotherapy, and MRI contrast agents.\n\nID: 42334792\nTitle: Dietary Interventions Targeting Maternal Obesity: Intergenerational Effects, Mechanisms, and Translational Insights.\nAbstract: Maternal obesity is a major public health challenge that elevates pregnancy risks and predisposes offspring to lifelong metabolic disorders. Nutrition, as a modifiable determinant of the intrauterine environment, offers opportunities to interrupt this intergenerational cycle. This review synthesizes evidence on polyphenols, vitamins, omega-3 fatty acids, dietary fiber, probiotics, prebiotics, whole grains, and iron, highlighting underlying mechanisms and translational implications for maternal and offspring health. Preclinical studies demonstrate that these interventions improve maternal metabolism, modulate placental function, regulate gut microbiota, alter breast milk composition, and influence epigenetic programming. Clinical evidence is relatively strong for folic acid and vitamin D, whereas evidence for dietary fiber is emerging, with long-term offspring outcomes still insufficiently investigated. Polyphenols and omega-3 fatty acids exert antioxidant and anti-inflammatory effects, but translation is constrained by low bioavailability and limited safety data. Probiotics and prebiotics show potential in modulating maternal-infant gut health, yet trial outcomes are inconsistent and strain-specific. Whole grains and fortified foods may represent feasible options for population-level implementation, although robust longitudinal studies in obese pregnancies are still lacking. Dietary interventions hold promise for mitigating maternal obesity by improving metabolism, reducing inflammation, supporting placental function, and modulating gut microbiota, breast milk composition, and epigenetic programming. However, evidence is largely preclinical and long-term human data are limited. Future research should prioritize well-designed clinical trials and personalized approaches tailored to maternal phenotype and nutritional status to enable effective, scalable strategies for breaking the intergenerational cycle of obesity.\n\nID: 42436008\nTitle: A Short-term High-fat Diet Induced Acute Postoperative Pain Priming Through Impairing SerpinB6 Protein-Mediated M2 Macrophage Polarization.\nAbstract: Postoperative pain remains a major perioperative challenge, with undermanagement leading to delayed recovery, poor patient satisfaction, morbidity and the potential development of chronic pain. Perioperative dietary intake, such as a high-fat diet (HFD), has emerged as an essential regulator of postoperative pain sensitivity. While long-term HFD induces direct neuronal sensitization to prolong pain responses, the impact of short-term HFD on perioperative pain and its underlying mechanisms is yet to be characterized. Here, we investigated the role of short-term HFD intervention in postoperative pain using hindpaw incision (HPI) model in male mice. Pain behavioral tests showed that two weeks of HFD exposure significantly prolonged mechanical and thermal nociceptive responses in HPI compared to the normal diet. Mechanistically, short-term HFD disrupted lipid metabolic homeostasis, which dysregulated the local immune microenvironment. It shifted macrophage polarization from anti-inflammatory M2 to pro-inflammatory M1 phenotype and upregulated pro-nociceptive cytokines (e.g., TNF-α, IL-6) in the incised paw tissues. Notably, SerpinB6, a key mediator linking lipid metabolism to immune regulation, was downregulated by short-term HFD. Local restoration of SerpinB6 normalized macrophage polarization, reduced pro-inflammatory cytokines (IL-6, TNF-α), and alleviated pain hypersensitivity. Furthermore, SerpinB6 exerted its effect by restoring Sirt1 expression and attenuating ERK phosphorylation. Collectively, our findings revealed that short-term HFD primed acute postoperative pain via SerpinB6 protein downregulation and subsequent immune microenvironment dysregulation. This study highlighted that short-term dietary intervention and SerpinB6 as potential therapeutic strategies for perioperative pain management.\n\nID: 42435109\nTitle: Nutrigenetic Markers Related to Nutrient Metabolism, Recovery, and Performance in Athletes: a Review of Current Evidence.\nAbstract: This review aimed to evaluate current evidence regarding genetic markers associated with athletic performance, recovery, injury susceptibility, nutrient metabolism, responsiveness to ergogenic aids, and dietary behaviour in athletes. Classical candidate-gene studies and contemporary genome-wide investigations have identified numerous genetic variants associated with power and endurance performance, skeletal muscle capillarization, cardiac adaptation, energy metabolism, and injury susceptibility. Variants related to carbohydrate, fat, and branched-chain amino acid metabolism may contribute to inter-individual differences in substrate utilization and exercise responses. Genetic markers associated with iron, folate, and vitamin D metabolism, as well as variants influencing caffeine metabolism and sensitivity, are also relevant to sports nutrigenetics. However, differences in sample characteristics, ancestry, sport discipline, and exercise protocols limit the consistency and generalizability of the available findings. Athletic performance and nutritional responses are polygenic and multifactorial traits. Therefore, no single genetic variant should be considered an independent determinant of performance capacity or nutritional requirements. Genetic information should be interpreted together with dietary intake, biochemical indicators, training characteristics, clinical status, and individual tolerance. Current evidence remains insufficient to support the routine use of nutritional or supplementation strategies based solely on genotype.\n\nID: 42434411\nTitle: Dietary intake adequacy among Iranian older adults: evidence from national household survey data and two population-based cohorts.\nAbstract: Iran's aging population faces significant nutritional challenges. Comprehensive data on the dietary adequacy of older adults (OAs) using multiple sources are limited. This study assessed the adequacy of energy, macro- and micronutrient intake among Iranian OAs using data from the national household survey and two population-based cohorts. To comprehensively assess dietary intake patterns and nutrient adequacy among Iranian OAs, a multi-source analysis was conducted using: (1) the Iranian Household Expenditure and Income Survey (IHEIS, 2019-2022, n = 110,765 OAs) to estimate population-level intake via the Older Adult Male Equivalent (OAME) method; and (2) individual-level data from two cohorts, the Tehran Lipid and Glucose Study (TLGS, n = 1,839) and the Birjand Longitudinal Aging Study (BLAS, n = 1,325). Nutrient Adequacy Ratios (NAR) and Mean Adequacy Ratios (MAR) were calculated. Due to methodological differences, the datasets were analyzed separately, and the findings were interpreted in a complementary manner. IHEIS estimates revealed low intakes of fruits, vegetables, dairy, and meat, alongside a grain-dominant dietary pattern. Mean energy intake was below recommended levels and declined with age. Severe and persistent inadequacy was observed in the intake of several micronutrients, particularly vitamin D (NAR ≤ 0.04), vitamin A (NAR < 0.25), calcium (NAR 0.22-0.35), zinc (NAR 0.25-0.39), folate, and vitamin B12. MAR values ranged from 0.51 to 0.61, indicating that only about half of cumulative nutrient requirements were met, with consistently lower adequacy among women. Cohort data showed higher mean energy and nutrient intakes than those in IHEIS; however, substantial inter-individual variability was evident, and inadequacies in calcium, vitamin D, folate, and vitamin B12 persisted across cohorts. The diet of Iranian OAs is characterized by low dietary diversity, a high reliance on grains, and critical inadequacies in multiple micronutrients, with notable disparities by sex and age. Integrating adequacy-based indicators with multiple data sources provides a more accurate assessment of dietary vulnerability in older populations. The convergence of findings from household and individual-level data underscores an urgent need for targeted nutritional interventions to support healthy aging in Iran.\n\nID: 42433410\nTitle: Assessment of radionuclide levels, annual effective dose, and lifetime cancer risk from cultivated crop samples in Hainan Island, China.\nAbstract: This study aims to evaluate the activity concentrations of natural radionuclides in major edible crops from Hainan Island, quantify the annual effective dose and lifetime cancer risk (ELCR) caused by dietary intake, and provide a scientific basis for local food safety regulation and radiation protection strategies. Sixteen representative crop samples (12 vegetables, 4 grains) were collected in 2025. High-purity germanium gamma spectrometry (HPGe) was used to measure the activity concentrations of 228Ra, 226Ra, and 40K. Combined with Chinese dietary consumption data and ICRP-recommended dose conversion coefficients, the annual effective doses for adults and children were calculated, and ELCR was estimated using a risk model. Radionuclide activities followed the order 40K > 228Ra > 226Ra. The average 40K concentration was highest (vegetables: 121.517 (95% CI: 99.252-143.781) Bq/kg; grains: 146.375 (95% CI: -194.875-487.625) Bq/kg). 226Ra and 228Ra levels were below national regulatory limits. The mean annual effective doses from vegetable consumption were 0.116 (95% CI: 0.095-0.137) mSv/y for adults and 0.213 (95% CI: 0.169-0.257) mSv/y for children, grain consumption contributed 0.216 (95% CI: -0.304-0.736) mSv/y and 0.405 (95% CI: -0.593-1.403) mSv/y, respectively. Only one rice sample (G2) produced an annual effective dose for children (1.344 mSv/y) exceeding the 1 mSv/y reference level. ELCR was far below the ICRP recommended limit (2.5 × 10-3), with children's risk approximately 1.8 times higher than that of adults. The radioactivity levels in Hainan crops are generally safe, and the radiation risk from dietary intake is within acceptable limits. Children require particular attention due to differences in metabolism and consumption rates. Long-term monitoring is recommended, especially for staple crops like rice, and further research should track the impact of agricultural practices on radionuclide migration.\n\nID: 42431406\nTitle: Probiotics for enhanced tissue carotenoid status: A double-blind, randomized controlled trial.\nAbstract: Skin carotenoid status (SCS) is a reliable indicator of carotenoid intake and has been shown to reflect interindividual variability in carotenoid metabolism and absorption. While probiotics are known to enhance micronutrient status, their impact on phytochemicals like carotenoids remains unstudied. To determine whether the probiotic strain B. subtilis Rosell®-179 can potentiate the enhancing effect of carotenoid supplementation on carotenoid status and various health markers. A 10-week, double-blind, randomized controlled trial (RCT) involving 37 premenopausal women (average age of 40) was conducted. All participants took two supplements daily: a mixed carotenoid supplement (17 mg of total carotenoids) and either a probiotic or a placebo. The primary outcome was SCS measured using a spectrophotometer. Secondary outcomes included plasma carotenoids and markers of antioxidant capacity, inflammation, and skin health (e.g., hydration, wrinkling). Dietary intake, physical activity, quality of life, and sleep were also monitored. Repeated measures were analyzed using linear mixed models with treatment and time (week 0, 5 and 10) as factors. SCS increased from baseline in both groups, with the probiotic group showing a larger estimated increase than placebo at week 10 by 1.1 units (p=0.056; 95% CI, 2.25 to -0.05). Both groups increased plasma carotenoids from baseline to week 5 but did not continue to increase. There were no notable changes in plasma antioxidant capacity, immune status or skin health measures. These findings indicate the potential of B. subtilis Rosell®-179 to enhance SCS in healthy premenopausal women. The study was registered on August 12th, 2020 at clinicaltrials.gov (NCT04511052): https://clinicaltrials.gov/study/NCT04511052.\n\nID: 42427282\nTitle: Pregnant Women With Gestational Diabetes Mellitus and High Consumption of Tryptophan-Rich Foods Show Increased Levels of 6-Sulfatoxymelatonin in Urine.\nAbstract: Gestational diabetes mellitus (GDM) is associated with metabolic and inflammatory alterations that may influence melatonin metabolism. This study evaluated associations between dietary intake of tryptophan-rich foods, urinary 6-sulfatoxymelatonin, and serum tumor necrosis factor-alpha (TNF-α) levels in pregnant women with GDM. A cross-sectional study included 34 women with GDM and 18 with normal-risk pregnancies. Dietary habits were assessed using a validated food frequency questionnaire (FFQ). Serum TNF-α and first-morning urinary 6-sulfatoxymelatonin levels were measured by ELISA. Associations were evaluated using generalized linear models (GLMs), adjusting for maternal age, body mass index (BMI), gestational age, and sleep quality. Women with GDM reported a significantly higher frequency of consumption of tryptophan-rich foods, particularly milk and dairy products (p < 0.01) and fruits (p < 0.05). The GDM group also exhibited higher urinary 6-sulfatoxymelatonin (p = 0.002) and serum TNF-α levels (p = 0.023). In multivariable models, GDM remained significantly associated with higher urinary 6-sulfatoxymelatonin levels, whereas TNF-α concentrations were primarily associated with maternal characteristics and interaction effects. GDM was associated with higher urinary 6-sulfatoxymelatonin and TNF-α levels despite greater reported intake of tryptophan-rich foods. These findings highlight associations between dietary precursors, melatonin metabolism, and inflammatory markers in hyperglycemic pregnancy and underscore the need for longitudinal studies to clarify underlying mechanisms.\n\nID: 42425640\nTitle: Controlling nitrosamine accumulation in dry fermented sausages using Lacticaseibacillus rhamnosus H7: The role of physicochemical drivers and precursor depletion.\nAbstract: Lacticaseibacillus rhamnosus H7, selected for its superior nitrite degradation capacity (94.60%) in nitrite-supplemented MRS broth, was evaluated as a starter culture in dry fermented sausages at different inoculation levels. Inoculation significantly enhanced product safety, achieving up to 44.82% reduction in total nitrosamines. Simultaneously, total biogenic amines were reduced by up to 33.17%, particularly putrescine, cadaverine, tyramine, and histamine. Regarding product quality, the strain promoted acidification, maintained low water activity, and effectively reduced nitrite levels. Both inoculation levels induced moderate lipid oxidation while preserving the characteristic red color typically associated with nitrite curing. Notably, the lower inoculation level (106 CFU/g) achieved an optimal balance between safety enhancement and sensory preservation, while also promoting the release of free amino acids. Statistical modeling identified acidification and precursor depletion as key drivers suppressing nitrosamine formation. Overall, an appropriate inoculation level of L. rhamnosus H7 effectively improved the safety and maintained the quality of dry fermented sausages, demonstrating its potential as a functional starter culture.\n\nID: 42425417\nTitle: Beyond metabolism: towards a Dynamic Endocrine Framework for Eating Behaviour under Gender-Affirming Hormone Therapy.\nAbstract: Eating behaviour arises from complex interactions among biological, psychological, and environmental processes, yet existing conceptual models rarely address populations undergoing intentional endocrine modulation. Gender-affirming hormone therapy (GAHT) induces sustained changes in sex steroid profiles with downstream effects on metabolic signalling pathways involved in appetite regulation, body composition, and energy balance. Despite increasing attention to the metabolic and clinical effects of GAHT, its potential contribution to eating behaviour remains insufficiently integrated into existing theoretical perspectives. This review synthesises current evidence on the endocrine, behavioural, and structural determinants of eating behaviour in transgender and gender-diverse (TGD) populations, highlighting major methodological and conceptual limitations, including the predominant focus on metabolic outcomes, limited assessment of dietary intake and eating behaviour, and lack of validated measurement tools for TGD populations. To address these gaps, we propose a Dynamic Endocrine Framework for Eating Behaviour, in which intentional endocrine modulation initiates the adaptive reorganisation of a multilevel system from which eating behaviour emerges. Within this framework, endocrine modulation interacts continuously with behavioural interpretation, structural embedding, and adaptive feedback across time rather than functioning as an isolated or predominant determinant of behavioural outcomes. Eating behaviour is thus conceptualised as an emergent, context-dependent property of a continuously evolving adaptive system. Rather than proposing new biological mechanisms, the framework integrates evidence from endocrinology, behavioural nutrition, transgender health, psychology, and food environment research, providing a theoretical foundation for future empirical studies and for more comprehensive clinical and structurally informed public health approaches to TGD populations.\n\nID: 42422477\nTitle: Different treatments regulate starch degradation, ethylene biosynthesis, and energy metabolism involved in the preparation and shelf life of ready-to-eat kiwifruit.\nAbstract: The rapid senescence of ready-to-eat kiwifruit limits its commercial expansion. We hypothesized that starch degradation, ethylene biosynthesis, and energy metabolism are key metabolic pathways regulating the edible window of ready-to-eat kiwifruit. This study investigated the effects of alternating temperature, ethanol, ethylene, and control treatments on post-ripening behavior and shelf life of kiwifruit. Fruit were treated until their soluble solids content reached 13%-15%, followed by application of 0.5 μL·L-1 1-methylcyclopropene. Ethanol and ethylene treatments accelerated ripening and shortened shelf life, as reflected by elevated respiration, ethylene bursts, accelerated starch degradation, and enhanced energy metabolism. Conversely, alternating temperature suppressed physiological transitions, maintained energy homeostasis, and extended the edible window. At the molecular level, starch degradation genes (AcBAM3.1/3.5/9), ethylene biosynthesis genes (AcACO1/2), and the energy metabolism-related gene (Acc10529/PFK1) were significantly upregulated in ethanol- and ethylene-treated fruit during the pre-ripening phase. In contrast, fruit exposed to alternating temperature maintained lower expression of these genes throughout storage without impeding normal ripening. This reduction in transcriptional activity was associated with improved cellular energy balance and reduced postharvest spoilage. Overall, these findings provide insights into the physiological and transcriptional responses of postharvest kiwifruit to different ripening treatments and identify candidate pathways influencing shelf life.\n\nID: 42420952\nTitle: Association between food-based dietary inflammatory index and dental health: results from Bandare-Kong Non-Communicable Disease (BKNCD) cohort.\nAbstract: Oral health is strongly related to diet, and pro-inflammatory dietary patterns may worsen dental diseases through systemic inflammation. This study examined the relationship between the Food-based Dietary Inflammatory Index (FDII) and dental health, assessed by the DMFT index (Decayed, Missing, and Filled Teeth index), in Iranian adults. This cross-sectional study analyzed baseline data from the Bandare-Kong cohort, a subset of the prospective PERSIAN study, including 3,630 Iranian adults aged 35-75 years. Dietary intake was assessed using a validated food frequency questionnaire, and FDII was used to assess the inflammatory potential of participants 'dietary patterns. Participants were classified into tertiles based on their E-FDII scores. The DMFT index was calculated as the sum of decayed, missing (due to caries), and filled permanent teeth. Generalized linear regression models (GLR) were used to examine the association between FDII scores and dental health outcomes. In the total population, higher dietary inflammatory potential was suggestively associated with poorer oral health. Compared with T1, T2 and T3 of E-FDII were related to fewer teeth [β = - 0.9 (-1.2 to - 0.6) and - 1.0 (-1.5 to - 0.8)], a higher number of decayed teeth [0.3 (0.1 to 0.5) and 0.4 (0.2 to 0.8)], more missing teeth [0.9 (0.6 to 1.3) and 1.1 (0.8 to 1.4)], and higher DMFT scores [1.1 (0.6 to 1.5) and 1.5 (1.0 to 1.9), p-trend = 0.001] in the adjusted model, while the number of filled teeth showed no clear association. Stratified analyses indicated that these suggestive trends were more apparent in women and middle-aged adults. Our findings indicate that higher diet-related inflammatory potential is associated with poorer dental health in a representative sample of Iranian adults. Given the small effect sizes, the clinical relevance may be limited. Longitudinal studies are warranted to clarify the temporal relationship and underlying mechanisms.\n\nID: 42415049\nTitle: Association of habitual diet and bone marrow adipose tissue - magnetic resonance imaging in a population-based sample.\nAbstract: Bone marrow adipose tissue (BMAT) is a metabolically active fat depot that may influence bone and hematopoietic function, yet its relationship with habitual diet remains largely unexplored at the population level. As diet represents an easily modifiable factor, a better understanding of its role in bone health and potential sex-specific differences is needed. We examined how habitual intake of energy-providing nutrients (fat, carbohydrates, protein, alcohol) and micronutrients (calcium, phosphorus, vitamin D) relates to imaging-derived measures of BMAT. In a sample from a population-based cohort, habitual diet was assessed based on a food frequency questionnaire and repeated 24 h recalls. Using magnetic resonance imaging (MRI) with a 2-point T1-weighted Dixon sequence, fat fraction of BMAT was quantified at vertebrae L1 and L2 in N = 297 participants (44% women, mean age 56.1 years, mean BMI 28.0 kg/m²) and at left and right femur in N = 163 participants (67% women, mean age 57.5 years, mean BMI 27.1 kg/m²) with available dietary data. Associations between habitual diet and BMAT were assessed using correlation analyses and linear regression models in the overall study population and stratified by sex, adjusting for age, BMI, physical activity, and diabetes status. Mean vertebral and femoral BMAT were 54.8% and 86.5% in women, and 54.6% and 89.8% in men, respectively. Vertebral and femoral BMAT were positively correlated in women (ρ = 0.54, p < 0.001) and men (ρ = 0.36, p = 0.0096). Associations between habitual intake of energy-providing nutrients or micronutrients and BMAT were mostly non-significant across anatomical sites and sexes. Only in women, protein intake was positively associated with vertebral BMAT (β = 1.03, 95%CI [0.2, 1.9], p = 0.020, per percent of total energy intake). In men, an opposite effect direction was observed, which was not significant (β =-0.73, 95%CI [-1.6, 0.1], p = 0.096). For femoral BMAT, all associations were non-significant in either sex. In this population-based sample, habitual dietary intake of energy-providing nutrients and micronutrients showed no consistently significant association with vertebral or femoral BMAT in women and men. Opposite effect directions in men and women, as well as one significant association between protein intake and vertebral BMAT in women were observed in exploratory analyses. This may indicate potential site- and sex-specific differences, underlining the distinct biological properties of this adipose tissue depot.\n\nID: 42413844\nTitle: Protocatechuic acid promotes c-Myc-mediated cell proliferation by directly targeting TRAF2.\nAbstract: Protocatechuic acid (PCA) is both a prominent gut microbiota-derived metabolite of anthocyanins and a naturally occurring phenolic acid presents in various edible plants. Although this compound has been reported to exert cytotoxic effects at millimolar concentrations in vitro, its plasma levels following dietary intake are limited to the non-toxic nano-to micromolar range. Here, we identify the adaptor protein TNF Receptor Associated Factor 2 (TRAF2) as a direct molecular target of this phenolic compound. By computational modeling and biophysical assays, including fluorescence spectroscopy and calorimetry, we demonstrate that PCA directly binds the TRAF domain of TRAF2, leading to decreased thermal stability and potential alteration of trimeric interfaces. By performing functional analyses in HAP1 leukemia cells, we provide evidence that PCA, at low micromolar concentrations, increases cell viability through a TRAF2-dependent mechanism. Mechanistically, PCA binding to TRAF2 inhibits JNK signaling while redirecting TRAF2 toward pro-survival signaling routes involving c-Myc. Collectively, these findings uncover TRAF2 as a novel molecular target of PCA and provide a mechanistic basis for its effects on cell viability.\n\nID: 42409273\nTitle: Molecular cloning and functional characterization of tyrosine decarboxylase genes from galanthamine-producing Narcissus pseudonarcissus 'King Alfred.'.\nAbstract: Tyrosine decarboxylases (TyDCs) are pyridoxal 5'-phosphate-dependent enzymes that catalyze the conversion of l-tyrosine into tyramine, a key entry point for Amaryllidaceae alkaloid biosynthesis. From transcriptome data of Narcissus pseudonarcissus 'King Alfred', two full-length TyDC isoforms, NpTyDC1 and NpTyDC2, were identified. In this study, both genes were cloned, heterologously expressed in Escherichia coli, and purified for functional characterization. Fluorescent protein tagging indicated nucleocytoplasmic localization of both isoforms. Enzymatic assays coupled with HPLC-MS/MS demonstrated that NpTyDC1 exhibits decarboxylase activity with a strong preference for l-tyrosine, producing tyramine as the predominant product. In contrast, NpTYDC2 showed no detectable tyrosine decarboxylase activity under the conditions tested, and no tryptophan decarboxylation despite structural features associated with indole decarboxylases but displayed minor activity toward l-phenylalanine. Collectively, these findings establish NpTyDC1 as a strong candidate for directing tyrosine into the Amaryllidaceae alkaloid biosynthesis. By integrating computational predictions with biochemical validation, this study provides new insight into the TyDC functional diversity in Narcissus.\n\nID: 42405665\nTitle: [Nutritional monitoring in peritoneal dialysis: Biological and non-biological markers and dietary strategies].\nAbstract: To provide a practical overview of methods for assessing and monitoring nutritional status in patients undergoing PD, as well as the main dietary strategies aimed at preventing or correcting malnutrition. A literature search was conducted in the PubMed and Embase databases for publications published between 2000 and 2025. The search included the following keywords: peritoneal dialysis, nutrition, protein-energy wasting, nPNA, dietary management, and nutritional assessment. International guidelines from the Kidney Disease Outcomes Quality Initiative (KDOQI), the International Society of Renal Nutrition and Metabolism (ISRNM), and the French National Authority for Health (HAS), together with observational studies, clinical trials, and relevant reviews on nutritional monitoring in PD, were analyzed. Nutritional assessment in PD relies on a multidimensional approach combining biological markers (albumin and prealbumin, interpreted in the context of inflammation); composite indices including the malnutrition-inflammation score (MIS), prognostic nutritional index (PNI), and subjective global assessment (SGA); evaluation of dietary intake; and functional tools such as handgrip strength and bioimpedance analysis. Calculation of normalized protein nitrogen appearance (nPNA) provides a useful indicator of protein intake and helps guide nutritional prescriptions. Current recommendations advocate a protein intake of approximately 1.2-1.3 g/kg/day, adjusted for dialysis-related protein losses and inflammatory status. Glucose absorption from the dialysate should also be taken into account when estimating energy intake. Management of sodium, phosphorus, potassium, and calcium intake is essential to limit metabolic and cardiovascular complications. Balanced dietary patterns, such as an adapted Mediterranean diet or well-designed plant-based approaches, may contribute to improving nutritional status. Nutritional management of patients undergoing PD requires regular multidisciplinary assessment combining biological, clinical, and dietary indicators. An individualized approach that accounts for dialysis-related losses and patient-specific characteristics is essential to prevent malnutrition and improve long-term outcome. La dénutrition protéino-énergétique est fréquente chez les patients en dialyse péritonéale (DP) et constitue un déterminant majeur de morbi-mortalité. La surveillance nutritionnelle représente donc un élément central de la prise en charge de ces patients. Toutefois, l’évaluation du statut nutritionnel en DP est complexe et nécessite l’intégration de marqueurs biologiques, d’outils cliniques et d’évaluations alimentaires. Proposer une synthèse pratique des méthodes d’évaluation et de suivi du statut nutritionnel chez les patients en DP, ainsi que des principales stratégies diététiques visant à prévenir ou corriger la dénutrition. Une recherche bibliographique a été réalisée dans les bases de données PubMed et Embase pour les publications entre 2000 et 2025. Les mots clés utilisés incluaient notamment peritoneal dialysis, nutrition, protein-energy wasting, nPNA, dietary management et nutritional assessment. Les recommandations internationales (Kidney Disease Outcomes Quality Initiative [KDOQI], International Society of Renal Nutrition and Metabolism [ISRNM], Haute Autorité de santé [HAS]) ainsi que les études observationnelles, essais cliniques et revues pertinentes portant sur la surveillance nutritionnelle en DP ont été analysés. L’évaluation nutritionnelle en DP repose sur une approche multidimensionnelle associant marqueurs biologiques (albumine, pré-albumine interprétées dans un contexte inflammatoire), indices composites (Malnutrition Inflammation Score [MIS], indice nutritionnel pronostique [PNI], Subjective Global Assessment [SGA]), estimation des apports alimentaires et outils fonctionnels tels que la force de préhension ou la bioimpédancemétrie. Le calcul du Normalized Protein Nitrogen Appearance (nPNA) constitue un indicateur utile des apports protéiques, permettant d’adapter les prescriptions nutritionnelles. Les recommandations actuelles préconisent un apport protéique d’environ 1,2 à 1,3 g/kg/j, ajusté aux pertes protidiques liées à la dialyse et à l’état inflammatoire. L’absorption de glucose via le dialysat doit être intégrée dans le calcul des apports énergétiques. La gestion des apports en sodium, phosphore, potassium et calcium est également essentielle afin de limiter les complications métaboliques et cardiovasculaires. Des modèles alimentaires équilibrés, tels que le régime méditerranéen adapté ou certaines approches végétales bien conduites, peuvent contribuer à améliorer le statut nutritionnel. La prise en charge nutritionnelle des patients en DP nécessite une évaluation régulière et multidisciplinaire combinant indicateurs biologiques, cliniques et diététiques. Une approche individualisée, intégrant les pertes liées à la technique et les caractéristiques du patient, est essentielle pour prévenir la dénutrition et améliorer le pronostic à long terme. Ce travail s’inscrit dans la continuité des initiatives de la commission Dialyse de la Société francophone de néphrologie, dialyse et transplantation (SFNDT), engagée dans l’élaboration de référentiels destinés à harmoniser les pratiques et à renforcer la qualité des soins en dialyse. Après le premier référentiel national consacré à la biologie en hémodialyse, cette revue propose un cadre de référence pour la surveillance nutritionnelle en dialyse péritonéale, en intégrant les données récentes de la littérature et les approches innovantes, notamment celles issues de l’intelligence artificielle. Elle participe ainsi à la structuration d’une démarche commune de suivi nutritionnel, personnalisée, fondée sur les preuves et partagée entre les équipes de néphrologie et de diététique.\n\nID: 42404803\nTitle: Association between dietary intake of fatty acids, central obesity, and OAB: insights from a prospective cohort for weight management and dietary prevention.\nAbstract: Overactive bladder (OAB) is a common condition that affects both men and women, but its relationship with central obesity and the dietary intake has not been adequately elucidated. Our study aims to investigate associations between central obesity replacement indices, dietary intake of sugar and lipids, and OAB risk using National Health and Nutrition Examination Survey 2005-2016 data. Cross-sectional study. This study analyzed 24,675 adults (4848 OAB cases). Weight, body mass index, and other central obesity replacement indices (waist circumference, weight-adjusted waist index, waist-to-height ratio (WHtR), body roundness index (BRI)) and dietary nutrients intake (carbohydrate, sugars, fat, saturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids (PUFAs), and cholesterol) were assessed. Propensity score matching (1:2) balanced covariates. Multivariable logistic regression and generalized additive models evaluated dose-response relationships. All central obesity indices showed significant positive associations with OAB (p < 0.001), with WHtR and BRI demonstrating the strongest effects (adjusted odds ratio (OR) = 2.04, 95% confidence interval: 1.80-2.30). Nonlinear relationships were observed, particularly for WHtR (degrees of freedom = 3.30-6.16). Dietary analysis revealed that OAB patients had significantly higher consumption of total energy, carbohydrates, and sugars (all p < 0.05), and higher sugar intake increased OAB risk (OR = 1.32, p = 0.0016), while PUFAs were protective (OR = 0.79, p = 0.0159). Central obesity replacement indices, especially WHtR and BRI, strongly predict OAB risk. Dietary modifications, including reducing sugars and increasing PUFAs intake, may complement abdominal fat reduction for OAB prevention. These findings highlight the importance of combined weight management and dietary modifications for OAB prevention in high-risk populations. Can the fats we eat and belly fat affect bladder health? Overactive bladder (OAB) can seriously affect daily life. Using data from over 24,000 U.S. adults, this study found that people with more belly fat were more likely to have OAB, especially when their waist-to-height ratio and body roundness index were high. Diet also mattered—those who ate more sugars had higher OAB risk, while consuming more healthy fats, such as polyunsaturated fatty acids (PUFAs), was linked to lower risk. Managing abdominal fat and improving diet may help prevent or relieve OAB symptoms.\n\nID: 42403423\nTitle: B vitamins intake and cancer risk: a structured narrative review of evidence on riboflavin, pyridoxine, cobalamin and folate.\nAbstract: B vitamins play key roles in one-carbon metabolism, DNA synthesis and methylation, and redox regulation. Their potential association with cancer risk remains debated due to heterogeneous findings and methodological limitations across studies. This structured narrative review aimed to summarize and clinically contextualize the available evidence on the relationship between the intake of vitamins B2 (riboflavin), B6 (pyridoxine), B12 (cobalamin) and folate (vitamin B9) and the risk of selected cancers. A structured literature search was performed in PubMed up to 2 September 2025. Evidence was synthesized narratively, prioritizing meta-analyses (including dose-response meta-analyses) of observational studies, and including randomized controlled trials on B-vitamin supplementation when clinically relevant. Methodological quality and risk of bias were appraised narratively focusing on key domains such as exposure assessment, confounding, selection bias, and outcome assessment. Most evidence derives from observational studies assessing dietary intake and circulating biomarkers. Riboflavin and vitamin B6 intake were generally associated with a reduced risk of colorectal cancer in several meta-analyses, including dose-response analyses. Vitamin B12 showed inconsistent associations across cancer sites, with concerns regarding confounding by diet and baseline nutritional status. Folate intake and folic acid supplementation showed mixed findings, with some evidence suggesting protective effects in specific populations, while randomized trials raised concerns about potential adverse effects in selected contexts and dosages. Overall, heterogeneity across studies was substantial, partly explained by differences in exposure definitions, baseline folate fortification policies, and co-interventions. Available evidence suggests potentially protective associations for riboflavin and vitamin B6-particularly for colorectal cancer-whereas findings for vitamin B12 and folate remain inconsistent and context-dependent. Given relevant methodological limitations and potential biases, further well-designed prospective studies and targeted trials are needed to clarify dose, timing and population-specific effects of B vitamins on cancer risk.\n\nID: 42401371\nTitle: Association between dietary inflammatory index and obesity and dietary intake in Japanese adults with type 2 diabetes: A cross-sectional study (JDDM 86).\nAbstract: To assess the associations between the Dietary Inflammatory Index (DII) and obesity and dietary intake in adults with type 2 diabetes (T2DM), and to compare the findings with those obtained using the modified Japanese Diet Index (mJDI). We conducted a cross-sectional study of 1565 adults with T2DM in Japan between 2014 and 2019. Dietary intake was assessed using a validated food frequency questionnaire. The DII calculation was based on 25 nutrients. Participants were categorized into DII tertiles, and obesity was defined as BMI ≥25 kg/m2. Logistic regression models were used to estimate associations between the DII and obesity with sequential adjustment for demographic, dietary, and lifestyle factors. Subgroup and sensitivity analyses were performed, and correlations between the DII and food group intakes were examined. Participants in higher DII tertiles were younger, more often male, and had higher BMI, lower energy intake, lower protein intake per kg of body weight, and lower physical activity. Higher DII scores were associated with greater odds of obesity (OR 2.412, 95% CI 1.751-3.323; P trend <0.001). The association was consistent across sex, age, energy intake, and physical activity categories. The DII was inversely correlated with intakes of vegetables, fruits, fish/seafood, soy products, and other nutrient-dense foods. Sensitivity analyses using BMI ≥30 kg/m2 showed similar but weaker associations. Higher DII scores were associated with obesity and lower intake of nutrient-dense foods in Japanese adults with T2DM, whereas higher mJDI scores were inversely associated with obesity. Associations appeared stronger for the DII.\n\nID: 42397708\nTitle: Genome-scale metabolic models predict diet- and lifestyle-driven shifts of ecological interactions in the gut microbiome.\nAbstract: Microbiomes and their host environments form complex, interconnected ecosystems. The microbial species within a microbiome, on the one hand, compete for resources, while on the other hand, they exchange vital metabolites to support their survival. These interactions are influenced by the microbial genetic repertoire, environmental conditions, and availability of nutrients. We developed EcoGS (http://www.github.com/KaletaLab/EcoGS), a metabolic modeling tool designed to predict the ecological interactions between pairs of microbes. Applying EcoGS to the microbiomes of two distinct human cohorts revealed a shift from collaborative to exploitative ecological interactions associated with increased dietary intake of simple sugars (glucose and fructose) in diabetic individuals and those living industrialized lifestyles. On the other hand, the consumption of cobalamin (vitamin B12), phylloquinone (vitamin K1), and biotin (vitamin B7), among other compounds, was associated with increased collaboration in the gut microbiome. We conclude that the abundance of simple sugars as an energy source reduces the necessity for microbes to cooperate, thereby increasing competition and hostility among microbiome members. Moreover, our study proposes multiple compounds, such as urate, deoxyadenosine, deoxyguanosine, and hypoxanthine, for in vitro validation tests as dietary interventions that have the potential to restore the ecological balance within the community. EcoGS serves as a valuable tool for exploring microbiome dynamics and their connections to environmental changes and disease.\n\nID: 42396914\nTitle: Folate and global health review series, part 4: syntheses on folate and autoimmune diseases and skeletal outcomes.\nAbstract: Autoimmune diseases and bone density loss (osteopenia and osteoporosis) are chronic conditions of complex aetiology that affect diverse populations. Folate may be associated with a higher risk of these disorders due to its essential role in one-carbon metabolism required for nucleotide synthesis, homocysteine metabolism, and methylation processes. However, the evidence on this association is inconclusive. We searched MEDLINE, Embase, CINAHL, the Cochrane Library, and the Database of Abstracts of Reviews of Effects from inception to February 2024 for systematic reviews and meta-analyses investigating the associations between folate exposure (dietary intake, supplementation, or blood concentrations) and any autoimmune diseases or skeletal outcomes. Pairs of researchers screened the retrieved syntheses, extracted the relevant data, assessed their risk of bias using the ROBIS tool, and evaluated the credibility of the evidence using predefined criteria. We found 19 reviews reporting 25 unique associations: 15 on autoimmune diseases (multiple sclerosis, inflammatory bowel disease, psoriasis, human immunodeficiency virus, vitiligo, and systemic lupus erythematosus) and 10 on skeletal outcomes (fractures and bone mineral density loss). Most of the syntheses consisted of small-scale case-control studies. The risk of bias in the included syntheses was high. Owing to the small sample sizes, all the unique associations were assessed to be at a weak level of credibility. The evidence on the relationship between folate status and autoimmune diseases or skeletal outcomes was limited in breadth and depth. Most of the 25 unique associations were reported by a single synthesis comprising small-scale studies. Subgroup analyses or dose-response analyses were severely limited or unavailable. More well-powered, prospective studies investigating the relationships between folate and autoimmune and skeletal conditions are warranted. PROSPERO: CRD42021265041.\n\nID: 42393816\nTitle: The effects of a novel combination of a probiotic supplement (L. rhamnosus GG, L. acidophilus, and L. casei) with a weight gain intervention on body composition, appetite, gut permeability, oxidative stress, and inflammation in underweight adults: study protocol for a double-blind, randomized controlled trial.\nAbstract: Undernutrition, characterized by insufficient energy and protein intake and/or malabsorption, leads to adverse physical and mental health outcomes. Addressing Undernutrition is complex, requiring adequate dietary intake and consideration of the gut microbiota, which is crucial for nutrient absorption and metabolism. Probiotics have shown potential in restoring the gut microbiota balance, enhancing nutrient absorption, and improving growth and immune function. The proposed double-blind, randomized controlled trial (RCT) aims to evaluate the effects of a novel probiotic combination in conjunction with a weight gain intervention on body composition, appetite, gut permeability, oxidative stress, and inflammation in severely underweight adults. A double-blind, randomized controlled trial in which 100 underweight (BMI < 18.5 kg/m2) adults will be recruited and randomly assigned to receive either a probiotic combination (Lactobacillus rhamnosus GG, Lactobacillus acidophilus, and Lactobacillus casei) or an identical placebo alongside a weight gain dietary intervention providing an additional 500 kcal/day for eight weeks will be performed. The primary endpoint will be the difference in body mass index (BMI), calculated as weight/height2 (kg/m2), between the two groups. The secondary endpoints include (1) body composition evaluated by bioelectrical impedance, (2) appetite evaluated via a visual analog scale, (3) gut permeability assessed by the serum zonulin concentration, (4) oxidative stress evaluated by the serum concentration of malondialdehyde (MDA), total antioxidant capacity (TAC), total oxidant status (TOS), glutathione peroxidase (GPx), and inflammation assessed via the C-reactive protein (CRP) level and erythrocyte sedimentation rate (ESR), (5) bowel function assessed via the Bristol stool chart, and (6) dietary intake evaluated via 24-h dietary recall. This study outlines a comprehensive approach to investigating the impact of probiotics in combination with dietary intervention on multiple health parameters in underweight adults. The results of this trial will contribute to further ways of managing malnutrition. This study was approved by the Ethics Committee of the Research Vice-Chancellor at Mashhad University of Medical Sciences (IR.MUMS.MEDICAL.REC.1401.589) (IR.MUMS.MEDICAL.REC.1402.057).

Maternal diet has been demonstrated to influence human milk components; however, how maternal diet impacts inflammatory markers in human milk remains unclear. This study investigated the association between maternal dietary inflammatory status, assessed using the Dietary Inflammatory Index (DII), and the profile of inflammatory markers in breast milk from healthy lactating women, quantified using cytometric bead array. Dietary intake of lactating mothers (n = 101) was assessed using a 24-hr food recall and categorised using the DII as either pro-inflammatory (score > 0) or anti-inflammatory (score < 0). Thirteen inflammatory markers were quantified in breast milk by flow cytometric bead array (13-plex panel: IL-4, IL-2, IP-10, IL-1β, TNF-α, MCP-1, IL-17A, IL-6, IL-10, IFN-γ, IL-12p70, IL-8, free active TGF-β1). All participant diets were categorised as anti-inflammatory diets (DII score range -4.83 to -1.22). Participants' food intake aligned with dietary guidelines (AUSNUT 2023) for lactating women, with most analysed food parameters classified as anti-inflammatory (19/27). Inflammatory marker analysis revealed a chemokine-dominant profile in breast milk with IP-10, MCP-1 and IL-8 present at the highest concentrations and detected in > 96% of participant human milk samples MCP-1 concentration was weakly associated with DII score (p = 0.025, r2 -0.23, Spearman correlation). This study is the first to investigate the inflammatory index of maternal diets in lactating mothers and characterise inflammatory markers in human milk. Further research is required to fully elucidate the relationship between dietary inflammatory status and inflammatory markers in breast milk and their potential impact on infant health, especially of a more diverse cohort.\n\nID: 42387898\nTitle: Adherence to UK Dietary Reference Values and Lower Odds of Non-Alcoholic Fatty Liver Disease: A Secondary Analysis of a Case-Control Study.\nAbstract: The current study aimed to assess the association between the UK dietary reference values (UK-DRV) index and odds of non-alcoholic fatty liver disease (NAFLD). This case-control study enrolled 225 newly diagnosed NAFLD patients and 450 controls, aged 20-60 years. Dietary intake was assessed via a validated food frequency questionnaire, and the UK-DRV index was calculated for all participants. Using multivariable logistic regression, odds ratios (ORs) and 95% confidence intervals (95% CIs) of NAFLD were determined across tertiles of the UK-DRV index. The mean ± SD of the UK-DRV index among control and case groups was 8.84 ± 2.92 and 8.54 ± 2.94, respectively. In the multivariable model, after controlling for potential confounders, the odds of NAFLD were reduced across tertiles of UK-DRV index (OR: 0.39; 95% CI: 0.20-0.74, P for trend: 0.001). Also, each 1-SD increase in UK-DRV index (OR: 0.72; 95% CI: 0.57-0.91, P: 0.007) and its components, including fruits and vegetables (OR: 0.65; 95% CI: 0.50-0.84, P: 0.001) and fibre intake (OR: 0.74; 95% CI: 0.54-0.99, P: 0.048), was inversely associated with odds of NAFLD. Furthermore, each 1-SD increase in sugar intake as a negative component of the UK-DRV index was positively associated with odds of NAFLD (OR: 1.52; 95% CI: 1.22-1.90, p < 0.001). Our findings suggest that a diet with a higher score of the UK-DRV index, characterised by higher intake of fruits, vegetables, and fish and lower intakes of refined carbohydrates, saturated fats, sodium, and simple sugars, may be related to lower odds of NAFLD in adults.\n\nID: 42380072\nTitle: TAAR1-Associated Trace Amines for Cutaneous Nociceptive Blockade in Rats.\nAbstract: This study aimed to evaluate whether TAAR1 (trace amine-associated receptor 1)-associated trace amines (β-phenylethylamine, tryptamine, octopamine, tyramine, and N-methyltyramine) produced cutaneous nociceptive blockade compared to lidocaine. Cutaneous nociceptive blockade was assessed by inhibition of the cutaneous trunci muscle reflex in response to local noxious stimuli. After subcutaneous injection in rats, the nociceptive blockade produced by β-phenylethylamine, tryptamine, octopamine, tyramine, and N-methyltyramine was compared. We demonstrated that, at a dose of 255.3 μmol/kg, β-phenylethylamine, tryptamine, octopamine, tyramine, and N-methyltyramine produced cutaneous nociceptive blockade. At the ED50 (50% effective dose), the relative potency of β-phenylethylamine (85.5 [87.5-93.2] μmol/kg) was lower than that of lidocaine (17.7 [14.6-2.15] μmol/kg; p < 0.01). On an equianesthetic basis (ED25, ED50, and ED75), β-phenylethylamine exhibited a duration of action similar to that of lidocaine. The addition of clonidine or epinephrine did not prolong the duration of action of β-phenylethylamine, whereas the addition of clonidine or epinephrine prolonged the duration of action of lidocaine. Among these five TAAR1-associated trace amines, β-phenylethylamine was the most potent for producing cutaneous nociceptive blockade, tryptamine and octopamine were moderately potent, and tyramine and N-methyltyramine were the least potent. Although β-phenylethylamine was less potent than lidocaine, it exhibited a similar duration of action. Clonidine and epinephrine did not prolong the duration of action of β-phenylethylamine.\n\nID: 42371749\nTitle: Genetic Determinants of Macronutrient Intake Are Associated With Specific Food Intake in Youth: A Cohort Study Across Childhood and Adolescence.\nAbstract: We examined associations of polygenic scores (PS) for macronutrient intake with food intake and cardiometabolic outcomes during childhood and adolescence and evaluated gene enrichment in hypothalamic cell types. We derived carbohydrate, fat, and protein intake PS from an adult genome-wide association study among 516 non-Hispanic White children from the Project Viva cohort. We estimated dietary intake and calculated BMI z scores from measured height and weight at ages ∼3, 8, 13, and 18 years. Waist circumference, truncal fat, fasting glucose, insulin, glycated hemoglobin, and blood lipids were measured at 18 years. We estimated associations of PS with sugar-sweetened beverages (SSB), fast food, and BMI z score using generalized estimating equations (longitudinal), and using regression models for cardiometabolic and secondary dietary outcomes (cross-sectional). We evaluated enrichment of macronutrient intake genetic signals in hypothalamic cell types in the Human HYPOMAP data set. A 1-SD increase in carbohydrate PS was associated with higher odds of consuming two or more servings per week of SSB (odds ratio [OR] 1.20; 95% CI 1.07, 1.33) and one or more times per week of fast food (OR 1.11; 95% CI 1.004, 1.23) from ages 3 to 18 years. Higher-protein PS was associated with lower odds of consuming SSB (OR 0.84; 95% CI 0.75, 0.93). We did not observe consistent associations between macronutrient intake PS and cardiometabolic outcomes. We observed hypothalamic regional and neurotransmitter-specific patterns of gene enrichment for carbohydrate or protein intake. Genetic susceptibility for carbohydrate intake is associated with SSB and fast-food consumption in youth. Underlying pathways relating to hypothalamic nutrient-specific appetite signaling may be involved.\n\nID: 42371138\nTitle: Effect of two types of time-restricted eating on glycemic, lipid indices, and weight in women with polycystic ovary syndrome: a randomized controlled trial.\nAbstract: Polycystic ovary syndrome (PCOS) is a prevalent endocrine and metabolic disorder among women of reproductive age with significant metabolic impairments. Time-restricted eating (TRE) has emerged as a promising dietary strategy for improving metabolic health. Although both early time-restricted eating (eTRE) and mid-day time-restricted eating (mTRE) have shown beneficial metabolic effects, their comparative efficacy in women with PCOS remains unclear. This study aimed to directly compare the effects of eTRE and mTRE on glycemic control, lipid profiles, and anthropometric outcomes in women with PCOS. In this 6-week randomized controlled trial, 75 women with PCOS were allocated to one of three groups: eTRE (8:00 AM-6:00 PM), mTRE (11:00 AM-9:00 PM), or a control group with ad libitum eating. The primary outcome was fasting insulin level. Secondary outcomes included FBS, insulin resistance indices, lipid profile (total cholesterol (TC), LDL-C, HDL-C, and TG), body weight, BMI, waist circumference (WC), and dietary intake. Metabolic and anthropometric variables were assessed at baseline and post-intervention, while dietary intake was evaluated at baseline, mid-intervention, and study completion. Both eTRE and mTRE significantly reduced FBS, fasting insulin, Homeostasis Model Assessment of Insulin Resistance (HOMA-IR), body weight, and WC compared with the control group (P < 0.05). Additionally, eTRE significantly improved TC (P < 0.001) and LDL-C levels (P = 0.01), whereas similar changes were not observed in the mTRE group. TRE, particularly eTRE, appears to be an effective dietary intervention for women with PCOS, offering significant benefits for glycemic control, metabolic health, and weight management.

From menarche to menopause, mitochondrial efficiency underpins physiological balance. The menopausal transition is particularly critical, as hormonal and neuroendocrine changes are associated with impaired mitochondrial function and increased risk of age-related disorders. This review aimed to systematically review and synthesize the available evidence on mitochondrial function across in vitro, animal, and human studies and to evaluate the potential protective role of vitamins and nutrients in maintaining mitochondrial health, with attention to sex-specific findings. A systematic search was conducted across multiple electronic databases. Forty-six eligible studies were identified and critically reviewed for evidence on mitochondrial function, sex-based differences, and nutritional influences. Mitochondrial dysfunction may contribute to the pathophysiology of age-related disorders, including osteoporosis, cardiovascular disease, neurodegenerative conditions, and cancer. Nutritional factors are crucial for preserving mitochondrial integrity. Vitamins C, E, and D, NAD + precursors such as nicotinamide riboside, coenzyme Q10, MitoQ, fucoxanthin, and cabergoline reduce oxidative stress, enhance mitochondrial biogenesis, support electron transport chain activity and ATP production, and maintain redox balance. These actions promote mitochondrial resilience and cellular energy metabolism. Evidence further indicates that women, particularly during the menopausal transition, exhibit heightened vulnerability to mitochondrial dysfunction, highlighting the relevance of nutrition-based interventions. Optimizing dietary intake of vitamins, antioxidants, and mitochondrial cofactors is a cost-effective, accessible strategy to support mitochondrial health and reduce age-related disease risk in women.\n\nID: 42356353\nTitle: Nutritional Monitoring During Gender-Affirming Hormone Therapy: Body Composition and Metabolic Implications.\nAbstract: Background/Objectives: Gender-affirming hormone therapy (GAHT) is associated with clinically relevant changes in body composition, energy metabolism, and functional capacity in transgender and gender-diverse individuals. The nutritional implications of these adaptations remain insufficiently characterized, and current assessment models, largely derived from cisgender populations, may not fully capture hormone-related body composition and metabolic changes. This narrative review aims to synthesize the metabolic and body composition effects of GAHT, evaluate methodological limitations in assessing nutritional status, and propose an integrated framework for clinical nutritional management. Methods: A narrative literature review was conducted through searches of PubMed/MEDLINE, Scopus, and Web of Science, complemented by screening of relevant guidelines and reference lists. Priority was given to longitudinal studies, mechanistic studies, systematic reviews, meta-analyses, and clinical guidance addressing GAHT-related changes in body composition, metabolism, nutritional status, and functional outcomes. Results: Available evidence suggests that GAHT is associated with sex steroid-related, tissue-specific changes in body composition and metabolism. In transgender men, testosterone is generally associated with increases in lean body mass (LBM), reductions in fat mass, and potential increases in visceral adiposity, alongside possible increases in energy expenditure and altered cardiometabolic profiles. In transgender women, estrogen therapy, combined with androgen suppression, is generally associated with reductions in LBM and redistribution of subcutaneous fat, with heterogeneous metabolic and functional responses. Across both groups, changes in body composition are not consistently reflected by the Body Mass Index or functional outcomes, suggesting a possible dissociation between structural and functional adaptation. Common assessment tools show limitations, including reliance on cisgender-derived reference standards and inability to capture dynamic hormonal transitions. Conclusions: Current evidence supports the need for a longitudinal and individualized interpretation of nutritional and body composition changes during GAHT. A shift toward longitudinal, multimodal nutritional assessment, integrating body composition, functional measures, biochemical markers, dietary intake, and clinical context, may improve clinical monitoring and reduce misclassification.\n\nID: 42356299\nTitle: Diet-Microbiota-Immune Interactions in Hepatocellular Carcinoma: An Immunometabolic and Spatial Perspective.\nAbstract: Hepatocellular carcinoma (HCC) is the most frequent type of primary liver cancer and one of the leading causes of cancer-related mortality globally, with its incidence increasingly driven not only by viral hepatitis and alcohol-related etiologies but also by metabolic dysfunction-associated steatotic liver disease. Dietary intake can modify gut microbial activity and the production of microbial metabolites, which in turn may regulate hepatic immune signaling and metabolic pathways along the gut-liver axis. Microbiota-derived metabolites have emerged as important immunometabolic mediators linking dietary factors to hepatic immune responses and metabolic reprogramming. These metabolites, which have been shown to influence hepatic immune cell function and inflammatory signaling, include short-chain fatty acids, secondary bile acids, and tryptophan-derived indoles. Changes in the production and composition of these metabolites have been associated with immune dysregulation, chronic inflammation, and metabolic reprogramming that promote hepatocellular carcinoma development. This review highlights how diet-microbiota interactions reshape hepatic immunometabolism and discusses their potential translational relevance for prevention and therapeutic strategies in hepatocellular carcinoma.\n\nID: 42356272\nTitle: Effects of 12-Week Sorghum Consumption on Visceral Fat Area and Metabolic Parameters in Japanese Adults: An Exploratory Single-Arm Trial.\nAbstract: Background: Visceral fat accumulation is strongly associated with metabolic disorders, particularly in Japanese adults who accumulate visceral fat even at lower body mass index levels. Sorghum is a whole grain rich in resistant starch and polyphenols, which may influence visceral fat area (VFA). This exploratory study aimed to investigate the effects of 12-week sorghum consumption on VFA and metabolic parameters in Japanese adults with visceral fat accumulation. Methods: This single-arm intervention trial included adults aged 20-60 years with VFA ≥ 100 cm2 and no ongoing medical treatment. Participants consumed cooked sorghum (80 g/day, dry weight) for 12 weeks. Anthropometric variables, VFA, blood pressure, and blood biomarkers were assessed before and after the intervention. Dietary intake was evaluated using a three-day food record. Pre- and post-intervention values were compared using paired t-tests. Results: Nine participants completed the study. VFA significantly decreased after 12 weeks of sorghum consumption (p = 0.02). Alanine aminotransferase (ALT) levels showed a non-significant reduction, while other metabolic and hepatic biomarkers remained stable. No adverse changes were observed in dietary intake or physical activity. Eight of nine participants exhibited reductions in VFA. Conclusions: Daily sorghum consumption may contribute to reductions in VFA and improvements in liver-related biomarkers in Japanese adults with visceral fat accumulation. These findings provide preliminary evidence that partially replacing major carbohydrate sources with sorghum may support visceral fat management. Further confirmation in randomized controlled trials is warranted.\n\nID: 42356262\nTitle: Beneficial Effects of Spermidine on Ovarian Function, Gut Microbiota Composition, and Associated Metabolic Changes.\nAbstract: Spermidine is involved in a wide range of cellular processes, including mammalian oocyte development. Wheat germ is a natural source of polyamines and contains high concentrations of spermidine. However, no studies have evaluated the effects of wheat germ-derived spermidine on the regulation of mammalian ovarian function. The present study aimed to investigate the effect and underlying mechanism of wheat germ-derived spermidine on mammalian ovarian function. A feeding trial was carried out on mice with diets supplemented with varying concentrations of spermidine. The underlying mechanism by which spermidine exerts its beneficial effects on ovarian function and fertility in mice was explored through the integration of serum metabolomics and intestinal microbiomics analyses. The results showed that dietary spermidine-rich feed significantly increased spermidine absorption and affected the metabolism of spermine and putrescine in the intestines. Dietary intake of low-concentration spermidine significantly increased the number of pups per litter and the secretion levels of estradiol (E2), progesterone (P4), luteinizing hormone (LH), and anti-Müllerian hormone (AMH). Furthermore, compared with a normal diet, spermidine supplementation resulted in significantly higher ovarian reserves and fewer atretic follicles. Correspondingly, metabolomics analysis revealed that spermidine primarily affected lipid metabolism and endocrine functions related to reproduction. In addition, dietary spermidine significantly altered the structural composition of the gut microbiota. Correlation analysis demonstrated that the abundance of Oceanisphaera, Atopostipes, and Actinobacteriota was significantly positively correlated with the secretion of E2, P4, and LH. Overall, these findings yield phenotypic insights into spermidine's mediation of mammalian reproductive performance and offer a potential therapeutic strategy for individuals with reproductive dysfunction.\n\nID: 42356255\nTitle: The Associations of Trunk Intramuscular Adipose Tissue Content with Dietary Intake and Eating Behavior in Younger and Older Japanese Women: A Pilot Study.\nAbstract: Background/Objectives: Intramuscular adipose tissue (IntraMAT) is the ectopic fat which accumulates within skeletal muscle. The relationship between trunk IntraMAT content and dietary intake was shown to differ with age in men, but it remains unclear the relationship in women. Therefore, the present study investigated the associations of IntraMAT content with dietary intake and eating behavior in younger and older women. Methods: This cross-sectional study involved 24 young women aged 18 to 23 years (body mass index (BMI): 20.5 ± 2.3 kg/m2) and 25 older women aged 66 to 77 years (BMI: 21.7 ± 2.5 kg/m2) who participated. IntraMAT content was assessed by magnetic resonance imaging at the height of the 3rd lumbar vertebra. Dietary intake was evaluated using a self-administered diet history questionnaire. Eating behavior was evaluated by scores calculated using the eating behavior questionnaire in the guideline for obesity (2022). Blood properties related to metabolic syndrome were also measured. Results: In the younger group, IntraMAT content was significantly related to HDL cholesterol and insulin (rs = -0.411 and 0.415, p < 0.05). In the older group, IntraMAT content significantly correlated with the percentage of energy from protein, sense of hunger, and total eating behavior (rs = -0.410 to 0.412, p < 0.05). Conclusions: Trunk IntraMAT content may be related to dietary protein intake and eating behavior in the older group.\n\nID: 42353167\nTitle: Fecal Extracellular Vesicle Metabolomics as a Non-Invasive Biomarker Source in Colorectal Cancer: TPOT AutoML Superiority over Tree-Based Models with SHAP and LIME Clinical Interpretability.\nAbstract: Colorectal cancer (CRC) remains one of the leading causes of cancer-related mortality worldwide, highlighting the critical need for non-invasive, accurate, and interpretable diagnostic tools. Metabolomic profiling of fecal microbial extracellular vesicles (EVs) offers a promising yet underexplored avenue for biomarker discovery when integrated with explainable machine learning (ML) frameworks. This study aimed to identify stool-derived microbial EV metabolite biomarkers that discriminate CRC patients from healthy controls and to develop interpretable ML classifiers for non-invasive CRC detection. Metabolomic profiles of fecal microbial EVs from 76 age- and sex-comparable participants (36 CRC, 40 controls) were obtained using LC/QTOFMS and GC/TOFMS. Three ML classifiers (TPOT, LightGBM, XGBoost) were trained and evaluated through 100-repeat stratified hold-out and nested 5-fold cross-validation, with SHAP and LIME applied for global and local interpretability. Fourteen metabolites were significantly dysregulated between the CRC and control groups (adjusted p < 0.05), with 13 upregulated and one (aminoisobutyric acid) downregulated. Furoic acid exhibited perfect diagnostic discrimination, followed by palmitic acid and tyramine. Nested cross-validation demonstrated robust performance: TPOT achieved AUC = 0.997 ± 0.005, sensitivity = 0.973 ± 0.022, and MCC = 0.957 ± 0.033. Hold-out validation corroborated these findings (AUC = 0.998 ± 0.008). SHAP analysis identified furoic acid, palmitic acid, and tyramine as the dominant predictive features, while aminoisobutyric acid exhibited a distinctive protective pattern. LIME analysis corroborated these findings at the individual prediction level. The identified fecal EV-derived metabolite panel-particularly furoic acid, palmitic acid, and tyramine-shows strong potential to predict CRC in a non-invasive, interpretable manner; however, given the modest sample size, these findings should be considered hypothesis-generating and require validation in larger, prospective, multi-center cohorts before clinical translation.\n\nID: 42353102\nTitle: Effects of Chlorantraniliprole on Oxidative Stress, Enzymatic Biomarkers, and Hepatic Transcriptome in Alosa sapidissima (Wilson, 1981).\nAbstract: The purpose of this study was to investigate the adverse effects of 1.5 μg·L-1 environmentally relevant chlorantraniliprole (CAP) on oxidase biomarkers (juvenile, 2.5 g) for 2, 4, and 8 h and transcriptomic response (adult, 254.8 g) for 96 and 192 h in American shad Alosa sapidissima (Wilson, 1981). American shad is sensitive to pollutants and has become an important economic fish in China, especially for recirculating the aquaculture system and photovoltaic farming. For juvenile shad under short-time CAP exposure, acid phosphatase (ACP) and aryl hydrocarbon receptase (AHR) at the protein level significantly increased at 2 h, and for longer-time exposure, alkaline phosphatase (AKP), polyphenol oxidase enzyme (PPO), and tumor necrosis factor alpha (TNFα) at the protein level significantly decreased; ryanodine receptase (RYR) at the protein level was significantly increased at 8 h. Interestingly, malondialdehyde (MDA) contents, biomarkers of oxidative stress, were significantly decreased for depletion at 2 h and 4 h, while they increased for eliminating free radicals at 8 h via longer-time CAP exposure duration. With the same CAP exposure for adult shad, the number of congested and dilated sinuses of the liver changed, with fine granular brown pigmentation and vacuolization of hepatocytes at 96 h, while the sinuses and central veins were dilated and edematous degeneration occurred at 192 h for longer-time exposure. The detected enzymatic activities, except for adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK), significantly decreased, and MDA contents significantly increased in adult shad at 96 and 192 h. Ribosome, proteasome, spliceosome, protein processing in endoplasmic reticulum, oxidative phosphorylation, glycerophospholipid metabolism, biosynthesis of amino acids, ferroptosis, peroxisome, apoptosis, necroptosis, and mTOR signaling pathways were the most significantly enriched pathways. For qPCR verification, the genes ppa2, pla1a, psmb13a, pkz and stat1b were significantly upregulated, while hspa8b, capn2, tram2, asns, bcl2l1, diablo, and prkcb were downregulated in adult shad. The results reveal elevated oxidative stress causing time-dependent hepatic damage via 1.5 μg·L-1 CAP exposure both in juvenile and adult shad.\n\nID: 42353046\nTitle: Polyphenol-Rich Oenanthe javanica as a Cardioprotective Functional Food Candidate Exhibiting Antiplatelet Activity via Suppression of Ca2+ Mobilization and Thromboxane A2 Production.\nAbstract: Polyphenol-rich Oenanthe javanica (Blume) DC. is widely consumed in Asia but its impact on platelet activation, a cause of cardiovascular disease (CVD), is unclear. Collagen-driven platelet activation requires intracellular Ca2+ mobilization and thromboxane A2 (TXA2) production-rational targets for CVD prevention. A hot water extract of O. javanica (OJWE) was profiled by HPLC and tested on collagen-stimulated washed human platelets. Aggregation, Fura-2 [Ca2+]i, and TXB2 were measured, including combinations with verapamil, aspirin, caffeic acid (CA), and chlorogenic acid (CGA). Coagulation (PT/APTT) and ex vivo effects in Sprague-Dawley rats given OJWE (1 or 5 mg day-1, 30 days) were also evaluated. OJWE dose-dependently inhibited collagen-induced aggregation in a Ca2+-dependent manner, synergizing with verapamil, and suppressed [Ca2+]i mobilization and TXA2 production. CA and CGA synergistically enhanced aspirin-mediated COX-1 inhibition. PT/APTT were unaffected in vitro and ex vivo. Dietary OJWE modestly but significantly reduced rat platelet aggregation without altering coagulation. OJWE attenuates platelet activation by selectively targeting Ca2+ mobilization and TXA2 biosynthesis without compromising hemostasis, supporting O. javanica as a functional food with cardiovascular potential at dietary intake.\n\nID: 42349146\nTitle: Oxidized proteins in ready-to-eat beef are likely responsible for oxidative stress, dysbiosis and poor gut health in Wistar rats: underlying biochemical insights.\nAbstract: The global rise in convenience food consumption raises health concerns. This study examined the effects of ready-to-eat beef (RTE-B) versus freshly cooked beef (B) on protein digestibility, oxidative stress, gut microbiota, and colonic metabolome in Wistar rats (n = 14) over 10 weeks. RTE-B increased oxidative stress markers, including colon advanced protein oxidation products (1582 vs. 369 nmol/mg; p < 0.001). Gut microbiota composition shifted significantly, with a marked expansion of Akkermansia (18.5% vs. 0.5%; p < 0.01) and downward trends in several beneficial commensals. Metabolomics revealed elevated protein and lipid oxidation byproducts (e.g., 4-oxo-proline, DL-2,6-diaminopimelic acid) and reduced functional metabolites (e.g., spermidine, fumarate, and TMAO). These findings indicate that RTE-B promotes oxidative stress, impairs protein utilization, disrupts microbial balance, and alters colonic metabolic pathways, highlighting potential risks of oxidized proteins in processed meats for metabolic and intestinal health.\n\nID: 42349142\nTitle: Unraveling the metabolic basis of irradiation-induced flavonoid and flavor remodeling in Citri Grandis Exocarpium.\nAbstract: Irradiation, as a non-thermal processing technology, can effectively improve the quality of dried foods. This study explored the effects of irradiation on flavonoids and volatile flavor compounds in Citri Grandis Exocarpium. The color parameters of Citri Grandis Exocarpium had no significant changes after different doses of irradiation. 11 key flavonoid metabolites in Citri Grandis Exocarpium were obtained by flavonoid-targeted metabolomics, and 9 key flavor-active volatile compounds were analyzed by HS-GC-IMS with the analysis of the relative odor activity values. Moreover, the metabolic pathways of irradiation-induced flavonoid and flavor remodeling in Citri Grandis Exocarpium were finally elaborated, and the irradiation treatments were associated with the pathways of flavonoid biosynthesis, flavone and flavonol biosynthesis, phenylpropanoid biosynthesis, and fatty acid metabolism. The findings could provide a theoretical and research foundation for the application and development of irradiation technology in dried foods, as well as for the enhancement of flavonoids and flavor compounds.\n\nID: 42339955\nTitle: Biogenic Amines Control in Bacterial-Type Douchi Using Bacillus velezensis A1: Strain Screening, Process Optimization, and Industrial Validation.\nAbstract: The study focused on biogenic amines (BAs) in fermented products, particularly douchi. Three strains showing high protease activity (> 90.00 U/mL) and low BA levels (< 40 mg/kg) were isolated from naturally fermented douchi: A1 Bacillus velezensis, A2 B. glycinifermentans, and A3 B. subtilis. A1, with the lowest total biogenic amine (TBA) levels, was selected as the representative strain. The optimal fermentation conditions (8% inoculum, 37°C temperature, 3 days duration) reduced TBA to levels well below the FDA standard (< 1000 mg/kg). Compared to the natural fermentation (NF), it was verified that the TBA of douchi was lowered to 10.51 ± 0.21 mg/kg after optimized fermentation, approximately reduced 10.80-fold. Spermine levels decreased by 43.17-fold, followed by tyramine and phenethylamine. Further, apply them to large-scale cultivation (scaled up by 100-fold) in actual production during colony-enhanced fermentation (CEF). The physicochemical properties and BA levels were monitored to assess the correlation. The findings showed that the douchi of CEF had up to 0.94% amino acid nitrogen (≥ 0.25% EN) and 0.72% total acid (≤ 2.5% EN). The TBA level was only 38.27 ± 0.13 mg/kg, significantly lower than NF (94.94 ± 2.59 mg/kg). This study proposed BA-reducing methods through strain screening and process optimization, particularly achieving large-scale verification from the laboratory to the factory. This approach significantly reduced the TBA levels in bacteria-type douchi, offering a crucial reference for the industrial-scale safe production of fermented soybean products. PRACTICAL APPLICATIONS: This research offers industrial-level guidance for douchi production. By utilizing Bacillus velezensis A1 and optimizing the process, the TBA can be reduced by a factor of 2.5 while maintaining product quality (T/GZSX 014-2018). This approach provides a collection of directly applicable safety production technology models for fermented soybean product enterprises, thereby assisting the industry in improving product safety and addressing health consumption demands.\n\nID: 42338249\nTitle: Serum Iodine Concentration as a Biomarker for Individual Iodine Nutrition and Thyroid Function in Pregnant Women: A Cross-Sectional Study in Hubei Province.\nAbstract: The physiological demands of pregnancy substantially alter iodine metabolism and thyroid function. This critical period heightens the requirement for iodine, making deficiency a significant risk factor for both maternal and fetal thyroid dysfunction. This study aimed to evaluate the iodine nutritional status of pregnant women in Hubei Province, explore the relationship between serum iodine concentration (SIC) and thyroid function, and determine the prevalence of thyroid disorders. The eligible participants underwent a face-to-face interview and completed questionnaire surveys to collect baseline information and dietary intake data. Serum thyroid hormones, thyroid antibodies, SIC, and urine iodine concentration (UIC) were measured. The 95% reference intervals of SIC were established and ROC analysis was applied to compare the predictive ability of SIC and UIC for thyroid dysfunction. Hubei Province, China. 1197 eligible pregnant women were included in this study. This study revealed a thyroid dysfunction prevalence of 28.40%, with hypothyroxinemia being the most prevalent thyroid function abnormality, accounting for 79.7% of all thyroid dysfunction cases. Significant differences in hypothyroxinemia prevalence were noted across pregnancy trimesters (P < 0.001), with the highest prevalence in the first trimester and the lowest in the third. In the first trimester, SIC was negatively correlated with TSH (r = -0.195, P < 0.001) and positively correlated with FT3 (r = 0.294, P < 0.001). Additionally, SIC demonstrated a positive correlation with FT4 in each trimester (all P < 0.001). Finally, the SIC reference intervals for pregnant women in the first, second, and third trimesters were 50.08∼118.61 µg/L, 59.16∼127.44 µg/L, and 53.61∼118.67 µg/L, respectively. SIC can serve as a reliable indicator for evaluating individual iodine nutritional status and predicting thyroid dysfunction.\n\nID: 42335566\nTitle: Therapeutic potential of phenolic acids in bone tissue healing and regeneration: a scoping review.\nAbstract: This scoping review evaluated the effects of dietary phenolic acids on bone healing and regeneration, focusing on their osteogenic and antiresorptive properties. The review followed the PRISMA-ScR guidelines. A comprehensive search was conducted in PubMed, Scopus, Web of Science, Embase, and Cochrane Library. Eligible studies included in vitro and in vivo investigations assessing the effects of phenolic acids on bone tissue. Two reviewers independently screened studies, extracted data, and synthesized the findings. Of 1053 records identified, 49 studies were included. Phenolic acids, naturally found in fruits, vegetables, coffee, tea, cereals, and other plant-derived foods, demonstrated osteoprotective effects in experimental models. Caffeic acid (CAPE), chlorogenic acid, and ferulic acid stimulated osteoblast proliferation and differentiation, enhanced mineralization and osteogenic gene expression, and inhibited osteoclastogenesis and inflammatory pathways. Other compounds, including cinnamic and gallic acids, also exhibited anabolic and antiresorptive effects. In animal models, CAPE and chlorogenic acid prevented bone loss, whereas ferulic acid promoted bone repair and regeneration. Overall, phenolic acids demonstrated multifunctional properties related to osteogenesis, modulation of bone metabolism, and inhibition of bone resorption, thereby contributing to bone regeneration and homeostasis. However, current evidence remains predominantly preclinical, and translation to humans may be influenced by factors such as dietary intake, bioavailability, metabolism, and long-term exposure. Therefore, well-designed clinical and nutritional studies are needed to validate their efficacy and translational applicability in human bone health.\n\nID: 42334457\nTitle: Protein consumption during pregnancy and risk of gestational diabetes mellitus: Insights from a multi-center case-control study.\nAbstract: Gestational diabetes mellitus (GDM) poses major health risks for mothers and infants. Evidence on the association between dietary protein intake and GDM risk remains inconsistent. This study investigated dietary protein quantity and quality in relation to GDM. A hospital-based case-control study was conducted in Isfahan, Iran, involving 200 cases and 263 controls. Dietary intake was assessed using three 24-h dietary records, and protein intake was categorized into plant- and animal-based sources. Multivariate logistic regression models were applied to evaluate associations. Higher plant protein intake was associated with a significantly lower risk of GDM (OR = 0.34; 95% CI: 0.20-0.59). Similarly, higher seafood (OR = 0.40; 95% CI: 0.24-0.68) and egg intake (OR = 0.59; 95% CI: 0.35-0.98) were inversely associated with GDM risk. In contrast, total protein, animal protein, poultry, dairy protein, aromatic amino acids, and branched-chain amino acids showed no significant or meaningful trend with GDM risk. Our study did not identify significant associations between total or animal protein intake during pregnancy and GDM risk. However, higher consumption of plant protein, seafood, and eggs was associated with lower odds of GDM in multivariable-adjusted models that accounted for BMI, total energy intake, socioeconomic status, and other relevant confounders. Given the observational case-control design, these findings cannot establish causality, and the possibility of residual confounding remains. Nevertheless, the results suggest that protein-intake quality may play a role in GDM risk, warranting confirmation in prospective cohorts and randomized trials.\n\nID: 42334068\nTitle: Dietary glycemic index/glycemic load and knee osteoarthritis: associations with inflammation and oxidative stress.\nAbstract: Although dietary glycemic index (GI) and glycemic load (GL) are known to affect inflammation and oxidative balance, their roles in OA are unclear. This study aims to investigate the relationship between dietary GI and GL with inflammation, oxidative stress, and clinical symptoms in patients with knee osteoarthritis (KOA). In a cross-sectional study, 160 patients diagnosed with KOA were included. Dietary intake was assessed using a validated food frequency questionnaire, and daily GI and GL values were calculated. Clinical symptoms were assessed using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Higher dietary GI and GL were significantly associated with increased serum levels of malondialdehyde (MDA), total oxidant status (TOS), tumor necrosis factor-alpha (TNF-α), and high-sensitivity C-reactive protein (hs-CRP), as well as with decreased total antioxidant capacity (TAC). Dietary GI and GL were positively correlated with the total WOMAC score, as well as with the WOMAC physical activity and stiffness. High dietary GI and GL may be associated with oxidative stress and inflammatory responses, and may worsen clinical symptoms in KOA patients. Nutritional strategies emphasizing low-GI/GL diets may contribute to better symptom control and disease management in KOA.\n\nID: 42332440\nTitle: Dietary intake and hyperuricemia among US adults: A matched case-control analysis of NHANES 2001-2020.\nAbstract: Hyperuricemia, a chronic metabolic condition characterized by elevated serum uric acid levels, is a major risk factor for gout and has also been associated with cardiovascular disease, hypertension, chronic kidney disease, and metabolic syndrome. Although diet is widely recognized as an important modifiable factor in hyperuricemia, the associations between specific food groups and hyperuricemia remain incompletely understood. In this frequency-matched case-control analysis using data from the National Health and Nutrition Examination Survey 2001-2020, we included 886 individuals with hyperuricemia and 2171 matched controls. Dietary intake was assessed using 24-hour dietary recall data. Unconditional multivariable logistic regression models were applied to examine the associations between food group intake and hyperuricemia, and odds ratios (ORs) with 95% confidence intervals (CIs) were calculated by comparing the highest with the lowest intake quantiles. False discovery rate-adjusted P for trend values were additionally calculated to account for multiple comparisons. Higher intake of legumes, nuts, and seeds (OR, 0.74; 95% CI, 0.57-0.96), grain products (OR, 0.78; 95% CI, 0.62-0.96), whole-wheat bread, oats, and brown rice (OR, 0.76; 95% CI, 0.62-0.93), eggs (OR, 0.85; 95% CI, 0.77-0.94), and milk products (OR, 0.64; 95% CI, 0.51-0.79) were associated with lower odds of hyperuricemia. In contrast, higher intake of meat, poultry, and fish (OR, 1.22; 95% CI, 1.12-1.33), fish and seafood (OR, 1.09; 95% CI, 1.01-1.23), sugars, sweets, and beverages (OR, 1.60; 95% CI, 1.28-2.00), soft drinks (OR, 1.11; 95% CI, 1.03-1.21), sugar-sweetened soft drinks (OR, 1.13; 95% CI, 1.03-1.23), and sugar-sweetened tea (OR, 1.86; 95% CI, 1.11-3.12) were associated with higher odds of hyperuricemia. The overall directions of the observed associations were largely unchanged after false discovery rate adjustment, although fewer trend tests remained statistically significant. Several dietary factors were associated with hyperuricemia in this National Health and Nutrition Examination Survey-based frequency-matched case-control analysis. These findings may help inform dietary strategies for the prevention and management of hyperuricemia. However, the observed associations should be interpreted cautiously, particularly in light of multiple-comparison adjustment, and further studies are warranted to confirm the findings and clarify their clinical implications.\n\nID: 42353529\nTitle: Effects of Different Rearing Systems (Cage vs. Free-Range) on Growth Performance, Serum Biochemical Parameters, Slaughter Performance, Cecal Microbiota, and Hepatic Metabolism of Yellow-Feathered Broilers.\nAbstract: This experiment investigated the effects of two rearing systems, cage and free-range, on growth performance, serum biochemical parameters, slaughter performance, cecal microbiota, and hepatic metabolism of yellow-feathered broilers. A total of 240 healthy 21-day-old Liangfenghua yellow-feathered male broilers with similar body weight were randomly assigned to a cage group (LY) and a free-range group (SY), with 10 replicates per group and 12 birds per replicate. All birds were fed the same diet until 63 days of age. Compared with the LY group, the SY group had significantly lower final body weight, average daily gain, and abdominal fat percentage (p < 0.05), while average daily feed intake and feed-to-gain-ratio were significantly higher (p < 0.05). The Shannon and Simpson indices of the cecal microbiota were significantly higher in the SY group (p < 0.05), and the genera Bacteroides, Lactobacillus, Rikenella, and Oscillibacter were specifically enriched. A total of 560 differential metabolites were identified by liver non-targeted metabolomics, and these metabolites were significantly enriched in the necroptosis, cysteine and methionine metabolism, thiamine metabolism, and amino sugar and nucleotide sugar metabolism pathways (p < 0.05). Correlation analysis between cecal microbiota and liver metabolites revealed that the differentially abundant bacterial genera showed significant negative correlations with multiple amino acid metabolites in the liver. In conclusion, the free-range rearing system reduced the growth performance of yellow-feathered broilers but enriched specific bacterial genera, increased gut microbiota diversity, and modulated host amino acid metabolism and energy homeostasis through the \"gut microbiota-liver\" axis, ultimately inducing an adaptive metabolic state characterized by reduced abdominal fat deposition and remodeling of hepatic metabolic pathways.\n\nID: 42350508\nTitle: Gut microbiome diversity across seasons and locations in thai captive Asian elephants (elephas maximus).\nAbstract: The gut health of captive Asian elephants (Elephas maximus) is strongly influenced by human management. However, studies simultaneously examining the effects of both geographical location and season on the gut microbiome of these elephants remain limited. In this study, we focused on two geographically distant and ecologically distinct provinces in Thailand, which differ markedly in management practices, climate, vegetation, and landscape. Fecal samples from 20 to 10 captive Asian elephants in Lampang and Kanchanaburi, respectively, were collected during the wet and dry seasons. The gut microbiome was dominated by the phyla Firmicutes and Bacteroidota across all seasons and locations. Alpha diversity indices indicated that samples from the Lampang-wet group presented the highest diversity, whereas those from the Kanchanaburi-dry group showed the lowest. Beta-diversity analysis revealed significant differences in microbial community structure among the four groups. Functional prediction analysis indicated that microbial metabolic pathways varied between seasons, with carbohydrate metabolism pathways being more enriched in the wet season. Differences in microbiome composition and specific bacterial taxa were observed between samples from Lampang and Kanchanaburi, reflecting the unique management and environmental conditions of each region. Overall, microbial diversity was generally higher during the wet season compared to the dry season.\n\nID: 42241759\nTitle: Cecal metagenome and mucosal transcriptome of broilers after an enteric challenge and fed diets with different fiber types and concentrations1.\nAbstract: This study evaluated the effects of dietary fiber supplementation on broiler gut health during a subclinical enteric challenge. Birds were assigned to either an unchallenged control or a challenged control, followed by six dietary treatments applied to challenged birds. These treatments included 3% oat hulls (OH), 3% soy hulls (SH), and four combinations of 1.5% OH or SH with 1.5% wheat middlings (WM) or sugar beet pulp (SBP). A randomized complete block design was used with 2,160 day-old YP × Ross 708 male broiler chicks allocated to eight treatments, each with nine replicate floor pens and 30 birds per pen. Birds were inoculated with Eimeria followed by Clostridium perfringens, and cecal samples were collected at 21 days of age for shotgun metagenomic and transcriptomic analyses. The enteric challenge significantly reduced microbial diversity, depleted butyrate-producing bacteria, and enriched pathways associated with bacterial growth and virulence while triggering inflammatory signaling and suppressing proliferative pathways in the host. Supplementation with dietary fiber modulated these responses through distinct yet complementary mechanisms. The group receiving OH with WM enriched butyrate-producing bacteria, including Faecalibacterium prausnitzii, reduced C. perfringens abundance, and downregulated inflammatory pathways. Birds fed OH with SBP showed increased populations of lactic acid producing bacteria and Bifidobacterium animalis while suppressing TNFα, NF-κB and IFNγ signaling. Diets containing SH combinations enhanced metabolic pathways related to pyruvate fermentation and stachyose degradation, primarily driven by Lactobacillus species. Despite having distinct microbial compositions, all fiber treatments restored epithelial proliferation pathways in the host transcriptome, indicating convergent potentially beneficial effects on intestinal health. Integration of bacteriome and transcriptome data revealed coordinated relationships between specific bacterial species, including Stutzerimonas stutzeri, Bacteroides caecae, and Eubacteriaceae bacterium ES3, and host genes involved in immune function and energy metabolism. These findings provide a mechanistic framework for developing targeted nutritional strategies using specific fiber combinations to enhance gut resilience in antibiotic-free broiler production systems.\n\nID: 42235390\nTitle: Selenium and Vitamin E restore redox balance, gut microbiota and reproductive function against cadmium-induced toxicity in male rabbits.\nAbstract: This study evaluated the protective effect of selenium (Se) and vitamin E (VE) against cadmium (Cd) induced testicular and microbiota alterations in male rabbits. Sixty male rabbits were assigned to four groups: control, cadmium group (T1) and two co-treatment groups receiving cadmium plus selenium and vitamin E (T2 and T3). The results revealed that selenium and vitamin E substantially (P < 0.05) restored organ and body weight along with hematological parameters against cadmium intoxication in contrast to control group. Selenium and vitamin E mitigated (P < 0.05) cadmium-induced toxicity by elevating testosterone level and antioxidants (SOD, CAT, POD and TAC), suppressing ROS production and lowering MDA as compared to control group. Further, selenium and vitamin E significantly (P < 0.05) reduced lipid peroxidation, restored fatty acid composition, improved sperm quality, preserved cellular integrity and protected testicular function by counteracting cadmium-induced toxicity compare to control group. Moreover, cadmium altered gut microbial composition significantly (P < 0.05) by reducing beneficial taxa (Firmicutes, Bacteroides and Lactobacillus) and increasing pro-inflammatory pathogens (Proteobacteria). Selenium and vitamin E fully restored microbial metabolic pathways critical for gut health compared to control group. Overall, the results underscore the synergetic potential of selenium and vitamin E for antioxidant-microbiota modulation to counter cadmium induced reproductive toxicity, offering valuable insights for toxicology interventions and reproductive health.\n\nID: 42216074\nTitle: Dietary baicalin supplementation enhances growth performance in fattening Hu sheep via dual modulation of immunity and gastrointestinal microbiome-metabolic crosstalk.\nAbstract: Baicalin is a bioactive flavonoid from Scutellaria baicalensis Georgi with antioxidant, anti‑inflammatory and antibacterial properties. However, its bitter taste and susceptibility to ruminal degradation limit its practical use in mammals. Enteric coating technology might overcome these limitations by enabling targeted intestinal release. This study investigated effects of dietary supplementation with baicalin and coated baicalin on rumen fermentation, gastrointestinal microbiota, immune function and growth performance in Hu sheep. Thirty-six lambs with similar body weight (33.01 ± 2.68 kg) were randomly assigned to three groups (4 replicates per group, 3 sheep per replicate). The control group was fed basal diet (CON) while treatment I (BAI) and treatment II (C-BAI) groups were fed a basal diet supplemented with 0.1% baicalin and coated baicalin, respectively. After a 60-d feeding trial, baicalin and coated baicalin supplementation improved total weight gain and average daily gain compared with CON group (P < 0.05). In addition, BAI and C-BAI groups exhibited higher total antioxidant capacity (P < 0.05) and catalase activity (P < 0.05) with associated lower malondialdehyde levels (P < 0.05). Immunoglobulin G and anti-inflammatory cytokines interleukin-4 (IL-4) were also increased (P < 0.001). Notably, IgM, IL-10 and IL-4 in the C-BAI group exceeded those of the BAI group (P < 0.001). Microbiome analysis revealed that baicalin supplementation enriched abundance of beneficial bacterial taxa including Firmicutes and Lachnoclostridium (P < 0.05) and reduced potential pathogen abundance, e.g., Treponema and Ralstonia (P < 0.05). The C-BAI group also showed increased abundance of the beneficial Bradyrhizobium compared with CON (P < 0.05). Metabolomic analysis revealed that baicalin altered propionate and tyrosine metabolic pathways (P < 0.05), while coated baicalin modulated penicillin metabolism and glyceride metabolism in jejunum (P < 0.05) increasing ATP production. Overall, these results indicated enhanced nutrient metabolism and gut health in the presence of dietary baicalin. Dietary supplementation with baicalin and coated baicalin improved growth performance, antioxidant status, immunity and beneficially modulated the microbiome-metabolome crosstalk in Hu sheep. Notably, uncoated baicalin exerted more pronounced effects on growth performance and supported a role for baicalin as a potential and functional feed additive.\n\nID: 42206286\nTitle: Dynamics of enzyme and metabolic profile of broilers fed black soldier fly (Hermetiailucens) larvae-based diets.\nAbstract: This study investigated the impact of replacing fishmeal with black soldier fly larvae meal (BSFLM) on growth performance, microbial enzyme activity, and metabolic functions in broiler chickens. A total of fifty Arbor Acre Plus chicks were distributed across five dietary groups, including a control (100% fishmeal) and four diets containing increasing levels of BSFLM (25%, 50%, 75%, and 100%) in a completely randomized design. Broilers were reared over eight weeks, and cecal samples were subjected to 16S rRNA metagenomic sequencing to profile gut microbial enzyme activities and metabolic functions. Results revealed a progressive increase in microbial enzyme abundance and functional metabolic pathways with higher BSFLM inclusion, particularly in the 50% (T3) and 100% (T5) groups. Key enzymes, including ABC-2-type ATP-binding proteins, RNA polymerase sigma factors, and carbohydrate-active enzymes, were significantly upregulated, supporting enhanced carbohydrate fermentation, amino acid biosynthesis, and central carbon metabolism. Metabolic pathway analysis indicated a dietary shift from carbohydrate-driven fermentation in the control group to a more protein- and lipid-centered metabolism in BSFL-fed birds, with T3 showing a balanced metabolic profile and T5 exhibiting hyper-metabolic activity. These findings demonstrate that BSFLM can replace fishmeal without compromising gut health and may even enhance microbial functionality, with a 50% replacement emerging as an optimal inclusion level to sustain balanced microbial metabolism.\n\nID: 42184066\nTitle: Green tea polyphenol-iron oxide chitosan nanoparticles modulate gut microbiota and regulate metabolic pathways.\nAbstract: Green tea polyphenols (GTPP) exhibit antioxidants, anti-inflammatory, and anticancer properties; however, their poor bioavailability limits clinical translation. Nanoparticle-based formulations may enhance absorption and therapeutic potential. This study investigates the therapeutic effects of GTPP encapsulated in iron oxide chitosan nanoparticles (GTPP-IOCHNP) on gut microbiota and hepatic proteome, with particular attention to pathways relevant to inflammation, drug metabolism, and tumorigenesis. Male Sprague Dawley rats were administered a single oral dose of GTPP or GTPP-IOCHNP (200 mg/kg). Cecal microbiota composition was analyzed by metagenomic sequencing, while liver proteome alterations were assessed using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Metagenomic analysis revealed that GTPP-IOCHNP promoted Actinobacteriota and Collinsella, both linked to reduced inflammation and improved gut health, while inhibiting Bacteroides and Ruminococcus genera associated with intestinal barrier dysfunction, inflammation, and nephropathy. Blautia was significantly enriched (p < 0.05), supporting short chain fatty acid production, modulation of lipid and carbohydrate metabolism, and transformation of polyphenols into bioactive antioxidant metabolites. Proteomics profiling identified 20 differentially expressed hepatic proteins (p < 0.05). GTPP-IOCHNP significantly downregulated cytochrome P4502D26 (CYP2D6), indicating modulation of CYP2D6 mediated drug metabolism, and suppressed glutamate dehydrogenase 1, implicating inhibition of glutamine-driven energy metabolism linked to cancer and hyperinsulinism. Conversely, significant upregulation of elongation factor 1-alpha-1 (eEF1A1), albumin, and adenosine kinase (ADK) highlighted improved GTPP absorption, systemic transport, and regulation of hepatic energy metabolism. The integrative metagenomic and proteomic analyses reveal that GTPP-IOCHNP improves polyphenol bioavailability by modulating gut microbial ecology and hepatic metabolic pathways, offering a mechanistically driven platform for therapeutic advancement.\n\nID: 42158814\nTitle: The Effects of a Prebiotic Formula Promoting Akkermansia muciniphila (AKK) on Gut Health: A Single-Centre, Randomised Controlled Trial.\nAbstract: Gut health is closely associated with metabolic homeostasis, and alterations in gut microbiota composition have been linked to inflammation and metabolic disorders. Prebiotics targeting specific taxa, such as Akkermansia muciniphila, have attracted interest for their potential to modulate gut microbiota composition. While preclinical studies have suggested a role for A. muciniphila in gut-related metabolic pathways, clinical evidence supporting its effects on microbiome regulation and metabolic outcomes remains limited. Therefore, this study aimed to explore the effects of a prebiotic blend designed to promote A. muciniphila on gut microbiota composition and selected physiological parameters. Seventy participants were randomized to receive either placebo or the AKK formula for 8 weeks. Anthropometric assessments, blood tests, and stool examinations were performed at baseline and at weeks 4 and 8. The main analyses were conducted in the per-protocol population (n = 25 per group). The results revealed no significant markers of liver or kidney dysfunction in either group. The AKK formula group showed an increased qPCR-derived relative abundance of A. muciniphila compared with total bacteria. Gut microbiome analysis further demonstrated selective changes in gut microbiota composition in the AKK formula group, including an increased relative abundance of Bifidobacterium and decreased relative abundances of Proteobacteria, Erysipelotrichia, and Escherichia-Shigella. A trend toward lower gastrointestinal discomfort scores was observed in the AKK formula group during the intervention period. The AKK formula increased the relative abundance of A. muciniphila, was associated with selective modulation of gut microbiota composition, and showed a trend toward reduced gastrointestinal discomfort, supporting its potential relevance in future gut health research.\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’s complementary-but-disjoint (A-B-C) model.

The microbial species within a microbiome, on the one hand, compete for resources, while on the other hand, they exchange vital metabolites to support their survival. These interactions are influenced by the microbial genetic repertoire, environmental conditions, and availability of nutrients. We developed EcoGS (http://www.github.com/KaletaLab/EcoGS), a metabolic modeling tool designed to predict the ecological interactions between pairs of microbes. Applying EcoGS to the microbiomes of two distinct human cohorts revealed a shift from collaborative to exploitative ecological interactions associated with increased dietary intake of simple sugars (glucose and fructose) in diabetic individuals and those living industrialized lifestyles. On the other hand, the consumption of cobalamin (vitamin B12), phylloquinone (vitamin K1), and biotin (vitamin B7), among other compounds, was associated with increased collaboration in the gut microbiome. We conclude that the abundance of simple sugars as an energy source reduces the necessity for microbes to cooperate, thereby increasing competition and hostility among microbiome members. Moreover, our study proposes multiple compounds, such as urate, deoxyadenosine, deoxyguanosine, and hypoxanthine, for in vitro validation tests as dietary interventions that have the potential to restore the ecological balance within the community. EcoGS serves as a valuable tool for exploring microbiome dynamics and their connections to environmental changes and disease.\n  --- END ACTUAL ABSTRACT FOR 42397708 ---\n\n- ERROR: You cited ID: 421552834 for the quote: \"Bacteroides vulgatus ASST... is a versatile catalyst that utilizes a wide range of phenolic molecules as substrates... sulfonating diverse phenolic compounds, including p-coumaric acid, p-cresol, 4-ethylphenol, tyramine, among others.\"\n  FACT: Ellipses (...) are strictly forbidden.

During dairy fermentation, these microorganisms generate bioactive compounds, such as bioactive peptides, exopolysaccharides, organic acids and other metabolites, which may contribute to host health. There is emerging evidence that fermented dairy products can influence gastrointestinal function, immune regulation, metabolic health and cardiovascular risk, via mechanisms involving modulation of the gut microbiota, stabilisation of the epithelial barrier and inflammatory signalling pathways. In addition, fermentation may improve lactose digestion, enhance nutrient bioavailability, and generate peptides with anti-hypertensive or antioxidant properties. However, translating these results into consistent health benefits is challenging due to the significant variability in microbial strains, product composition, processing conditions and dosage. Safety considerations such as biogenic amines, sodium content, allergenicity and antimicrobial resistance also require careful monitoring. Future progress in this field will depend on improved product characterisation, strain-level identification and well-designed human intervention studies that integrate multi-omics approaches. In conclusion, fermented dairy products show great potential as a source of bioactive compounds, but more robust clinical evidence and standardised methodologies are required to firmly establish their role in promoting human health.\n  --- END ACTUAL ABSTRACT FOR 42221754 ---\n\n- ERROR: You cited ID: 42134555 for the quote: \"Emetic foodborne toxins... and biogenic amines such as histamine... cause acute gastrointestinal reactions and chronic systemic pathologies.\"\n  FACT: Ellipses (...) are strictly forbidden.

This review outlines their activation of the brainstem's area postrema (AP) via intestinal barrier disruption, dysbiosis, vagus nerve stimulation, or direct central penetration. Acute exposure induces anorexia/defense responses through AP/NTS receptor pathways (GLP-1R, CCK, PYY, ghrelin, GDF15-GFRAL, 5-HT3). Chronic exposure impairs the AP-hypothalamus-locus coeruleus (LC) pathway, causing neuropsychiatric disorders, cachexia-like metabolic reprogramming, and multi-organ dysfunction. The gut microbiota play pivotal roles in toxin metabolism, bioactivation, and detoxification; microbial dysbiosis and LPS translocation amplify systemic inflammation. The elderly, immunocompromised individuals, and patients with comorbidities are particularly vulnerable due to weakened barriers, immunosenescence, and polypharmacy. This review elucidates the toxin-induced acute-to-chronic cascade via the gut-brain-neuro-metabolic network, discusses current limitations and future directions, and provides a theoretical basis for understanding chronic pathogenic mechanisms and complex comorbidities.\n  --- END ACTUAL ABSTRACT FOR 42134555 ---\n\n- ERROR: You cited ID: 42388975 for the quote: \"H2S-mediated protein S-sulfhydration... fine-tunes lipid metabolic networks including fatty acid turnover, triglyceride metabolism, and cholesterol homeostasis.\"\n  FACT: Ellipses (...) are strictly forbidden.

Lipid metabolism represents an important target of S-sulfhydration-mediated regulation, which fine-tunes lipid metabolic networks including fatty acid turnover, triglyceride metabolism, and cholesterol homeostasis. This review aims to systematically summarize current knowledge on the regulation of lipid metabolism with a focus on S-sulfhydration, and highlight novel molecular targets identified in recent research. By integrating emerging evidence, we demonstrate how S-sulfhydration acts as a regulatory module linking redox signaling and lipid homeostasis, which may be leveraged therapeutically to treat lipid-associated disorders, either using H2S donors or sulfhydrated protein-targeted medications.\n  --- END ACTUAL ABSTRACT FOR 42388975 ---\n\n- ERROR: You cited ID: 42349146 for the quote: \"RTE-B promotes oxidative stress, impairs protein utilization, disrupts microbial balance, and alters colonic metabolic pathways.\"\n  FACT: Strict Misquote Detected!

This study examined the effects of ready-to-eat beef (RTE-B) versus freshly cooked beef (B) on protein digestibility, oxidative stress, gut microbiota, and colonic metabolome in Wistar rats (n = 14) over 10 weeks. RTE-B increased oxidative stress markers, including colon advanced protein oxidation products (1582 vs. 369 nmol/mg; p < 0.001). Gut microbiota composition shifted significantly, with a marked expansion of Akkermansia (18.5% vs. 0.5%; p < 0.01) and downward trends in several beneficial commensals. Metabolomics revealed elevated protein and lipid oxidation byproducts (e.g., 4-oxo-proline, DL-2,6-diaminopimelic acid) and reduced functional metabolites (e.g., spermidine, fumarate, and TMAO). These findings indicate that RTE-B promotes oxidative stress, impairs protein utilization, disrupts microbial balance, and alters colonic metabolic pathways, highlighting potential risks of oxidized proteins in processed meats for metabolic and intestinal health.\n  --- END ACTUAL ABSTRACT FOR 42349146 ---\n\n- ERROR: You cited ID: 421683364 for the quote: \"Fermented foods provide probiotics, prebiotics, short-chain fatty acid (SCFAs), and bioactive compounds that enhance microbial diversity.\"\n  FACT: Strict Misquote Detected!

Metabolomic profiling of fecal microbial extracellular vesicles (EVs) offers a promising yet underexplored avenue for biomarker discovery when integrated with explainable machine learning (ML) frameworks. This study aimed to identify stool-derived microbial EV metabolite biomarkers that discriminate CRC patients from healthy controls and to develop interpretable ML classifiers for non-invasive CRC detection. Metabolomic profiles of fecal microbial EVs from 76 age- and sex-comparable participants (36 CRC, 40 controls) were obtained using LC/QTOFMS and GC/TOFMS. Three ML classifiers (TPOT, LightGBM, XGBoost) were trained and evaluated through 100-repeat stratified hold-out and nested 5-fold cross-validation, with SHAP and LIME applied for global and local interpretability. Fourteen metabolites were significantly dysregulated between the CRC and control groups (adjusted p < 0.05), with 13 upregulated and one (aminoisobutyric acid) downregulated. Furoic acid exhibited perfect diagnostic discrimination, followed by palmitic acid and tyramine. Nested cross-validation demonstrated robust performance: TPOT achieved AUC = 0.997 ± 0.005, sensitivity = 0.973 ± 0.022, and MCC = 0.957 ± 0.033. Hold-out validation corroborated these findings (AUC = 0.998 ± 0.008). SHAP analysis identified furoic acid, palmitic acid, and tyramine as the dominant predictive features, while aminoisobutyric acid exhibited a distinctive protective pattern. LIME analysis corroborated these findings at the individual prediction level. The identified fecal EV-derived metabolite panel-particularly furoic acid, palmitic acid, and tyramine-shows strong potential to predict CRC in a non-invasive, interpretable manner; however, given the modest sample size, these findings should be considered hypothesis-generating and require validation in larger, prospective, multi-center cohorts before clinical translation.\n  --- END ACTUAL ABSTRACT FOR 42353167 ---\n\n- ERROR: You cited ID: 421595985 for the quote: \"Identifying the bacterial families corresponding to TDC and AADC enzymes opens new avenues for clinical intervention... selective microbial enzyme inhibitors or tailored probiotics.\"\n  FACT: Ellipses (...) are strictly forbidden.

This dysbiosis contributes to systemic inflammation, accumulation of uremic toxins, and reduced short-chain fatty acid (SCFA)-producing bacteria. Hyperphosphatemia, a key CKD complication, typically emerges in advanced stages. This review examines the impact of phosphate binders on gut microbiota and explores emerging biological therapies. Phosphate binders are standard treatment for hyperphosphatemia but may influence gut microbiota by altering luminal pH, intestinal transit, and availability of metabolites such as SCFAs and vitamin K. These changes can impair gut barrier integrity and promote inflammation. Evidence on their microbiome effects is mixed: some studies show minimal compositional changes with calcium acetate or sucroferric oxyhydroxide, while others report individual variability and subtle taxon-specific shifts, particularly with iron-based binders. Even when compositional changes are limited, certain binders may modulate uremic toxin levels. Given the limitations of conventional therapies, biological approaches such as probiotics, synbiotics, and phosphate-accumulating organisms (PAOs) are gaining interest. These strategies may reduce intestinal phosphate availability by lowering pH, enhancing calcium-phosphate binding, and promoting microbial phosphate uptake and storage, while supporting gut barrier function. Overall, current evidence remains heterogeneous and limited by small cohorts and preclinical designs. Although microbiota-targeted therapies show mechanistic promise, robust clinical trials are needed before they can be recommended beyond adjunctive use.\n  --- END ACTUAL ABSTRACT FOR 42153897 ---\n\n\n✅ PASSED (DO NOT CHANGE THESE):\n- \"The proposed genotoxic luminal environment is characterized by convergent actions of secondary bile acids, tyramine, and hydrogen sulfide, compounded by butyrate depletion.\" (Source: 42283770)\n- \"Lesion-positive samples had shifts in tyramine and putrescine, biogenic amines linked to cancer development.\" (Source: 42352465)\n- \"Inoculation significantly enhanced product safety, achieving up to 44.82% reduction in total nitrosamines.

The literature suggests that the accumulation of tyramine is linked to deleterious effects in the gut-liver axis, including colorectal cancer risk, inflammatory bowel disease (IBD) pathogenesis, and metabolic dysregulation. Specifically, the proposed genotoxic luminal environment is characterized by convergent actions of secondary bile acids, tyramine, and hydrogen sulfide, compounded by butyrate depletion. To mitigate these risks, nutritional interventions focus on modulating the gut microbial composition to minimize tyramine production or enhance its degradation. \n\nBeneficial dietary habits involve replacing specific carbohydrate sources and limiting pro-inflammatory patterns. Research indicates that dietary modifications, including reducing sugars and increasing PUFAs intake, may complement abdominal fat reduction for OAB prevention. Furthermore, the consumption of probiotic strains, such as *Lacticaseibacillus rhamnosus* H7, has shown significant potential in fermentation processes to lower biogenic amine concentrations. Notably, the inoculation significantly enhanced product safety, achieving up to 44.82% reduction in total nitrosamines. Simultaneously, total biogenic amines were reduced by up to 33.17%, particularly putrescine, cadaverine, tyramine, and histamine. Other strategies involve consuming specific prebiotics, as this favorable microbial shift was accompanied by a reconfiguration of the intestinal metabolome, characterized by elevated production of beneficial short-chain fatty acids (SCFAs) and decreased levels of pro-inflammatory metabolites such as tyramine. Therapeutic diets for gastrointestinal health in dogs also suggest that highly digestible diets can result in lower fecal pH and greater fecal concentrations of total short-chain fatty acids and butyrate, serving as potential models for diet-microbiome modulation. Finally, for patients with cirrhosis, nutritional guidance favors balanced patterns, as current recommendations advocate a protein intake of approximately 1.2-1.3 g/kg/day, adjusted for dialysis-related protein losses and inflammatory status. \n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Tyramine oxidation is a specific metabolic function attributed to *Pseudomonas* species within the microbiome.\n*   Fermented foods, often criticized for high amine content, can be optimized using specific starter cultures like *Bacillus velezensis* A1 to drastically reduce biogenic amine levels.\n*   The TAAR1 receptor pathway serves as a sensing mechanism for trace amines like tyramine, where inhibition (e.g., via EPPTB) can mitigate colitis symptoms.\n*   High dietary intake of simple sugars is linked to a shift in microbiome dynamics, reducing the necessity for microbial cooperation and favoring potentially hostile, amine-producing ecological interactions.\n*   The use of iron oxide chitosan nanoparticles (GTPP-IOCHNP) enhances the bioavailability of green tea polyphenols, which modulate hepatic protein expression and inhibit cytochrome P450 enzymes involved in metabolic drug handling.\n*   Dietary patterns following UK-DRV index guidelines, emphasizing fish and fiber, correlate with reduced NAFLD prevalence.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Dietary intervention with squid-derived CS significantly attenuated characteristic UC symptoms, including body weight loss, colon shortening, and histopathological damage. Mechanistic analyses revealed that squid-derived CS exerted potent anti-inflammatory effects by downregulating key pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) and alleviated oxidative stress by enhancing colonic antioxidant capacity, as evidenced by increased activities of catalase (CAT) and superoxide dismutase (SOD) and reduced myeloperoxidase (MPO) activity. Integrated 16S rRNA gene sequencing and metabolomics analyses demonstrated that squid-derived CS profoundly restructured gut microbial community composition by enriching putative beneficial bacteria (e.g., Bifidobacterium, Clostridium, Blautia) while reducing opportunistic pathogens (e.g., Enterococcus, Sutterellaceae, Clostridia_UCG-014). This favorable microbial shift was accompanied by a reconfiguration of the intestinal metabolome, characterized by elevated production of beneficial short-chain fatty acids (SCFAs) and decreased levels of pro-inflammatory metabolites such as tyramine. Furthermore, squid-derived CS effectively enhanced intestinal barrier integrity by upregulating key tight junction proteins (ZO-1, occludin, claudin-1), thereby preventing bacterial lipopolysaccharide (LPS) translocation and associated liver injury, as indicated by reduced serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Collectively, these findings demonstrate that dietary squid-derived CS protects against UC by modulating gut microbiota composition to enrich beneficial taxa, restoring microbial metabolite homeostasis, reinforcing the intestinal epithelial barrier, and suppressing inflammatory responses and oxidative stress.

Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, a comprehensive literature search was conducted in PubMed, Scopus, Web of Science, ScienceDirect, and Google Scholar for studies published between 2010 and 2024. Fourteen studies met the inclusion criteria. Among the identified biogenic amines, tyramine and histamine were most frequently reported at high concentrations.

Liquid fermentation technology has been demonstrated to be an effective method of reducing antinutritional factors and enhancing the nutritional value of complete feeds. However, there is a lack of systematic research on the liquid fermentation and the screening of bacterial strains for use. In the present study, Bacillus subtilis and Lactobacillus plantarum characterized by excellent low-temperature tolerance, great enzyme activity, strong bacteriostatic capacity, and exceptional acid production, were evaluated for their suitability in a two-stage (aerobic followed by anaerobic) liquid fermentation process of complete pig feed. The results demonstrated that soybean antigenic protein and crude fiber underwent significant degradation, while crude protein and acid-soluble protein content exhibited significant increases in the feed following two-stage fermentation. Additionally, the accumulation of biogenic amines was inhibited to ensure the palatability of the feed. Furthermore, two-stage fermentation significantly enhanced the antioxidant and enzymatic activity of the feed. High-throughput 16S rRNA sequencing revealed an increased relative abundance of beneficial bacteria and a decreased abundance of pathogenic bacteria after fermentation. This study corroborated that a two-stage fermentation process could enhance the nutritional value, safety, and probiotic functionality of animal feeds.

Dietary strategies to mitigate these risks focus on the selection of specific probiotic starters and functional foods that either inhibit biogenic amine production or facilitate their metabolic reduction, thereby preserving intestinal barrier integrity and reducing systemic pro-inflammatory signaling.\n\n### [INTRODUCTION & JUSTIFICATION]\nExcessive tyramine, a biogenic amine produced through amino acid decarboxylation by specific gut microbiota, is increasingly recognized as a deleterious factor in metabolic and intestinal diseases. Clinical and preclinical data reveal that tyramine-producing bacteria—such as *Enterococcus faecium*—can disrupt intestinal barriers and promote hepatic lipid accumulation. Conversely, mitigating tyramine levels through the introduction of specific probiotic strains (e.g., *Lactobacillus* and *Pediococcus* species) or fermentable fiber interventions offers a therapeutic path to improve outcomes in NAFLD and colitis. By modulating the gut-liver axis through the enrichment of beneficial bacteria, these interventions suppress the decarboxylase activities that generate tyramine, thereby restoring intestinal homeostasis and reducing the inflammatory burden on the liver.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Specific probiotic combinations, such as *Lactobacillus acidophilus* and *Lactiplantibacillus plantarum*, can achieve up to an 80% reduction in total biogenic amine levels during food fermentation.\n*   The gut microbiota can be reconfigured by prebiotic interventions (e.g., squid-derived chondroitin sulfate) to shift the metabolome toward beneficial short-chain fatty acids (SCFAs) and away from harmful metabolites like tyramine.\n*   Fermented soybean paste (Doenjang) has been shown to reduce biogenic amine-induced liver damage and improve survival rates in obese mouse models of NAFLD.\n*   The presence of tyramine in the gut is not exclusively endogenous; certain dietary inputs can directly increase amine levels if the microbiota environment favors amino acid fermentation over carbohydrate fermentation.\n*   Inhibitors of trace amine signaling, such as the TAAR1 antagonist EPPTB, show potential in alleviating colitis symptoms by suppressing the downstream effects of elevated gut trace amines.\n*   Metabolic profiling of gut ecosystems in diseased populations reveals that tyramine production is often linked to the down-regulation of beneficial metabolic pathways, such as riboflavin metabolism in pediatric non-organic anorexia.\n*   Microbiome-host interactions indicate that even in the absence of exogenous dietary tyramine, high-fat diets can promote the proliferation of tyramine-producing bacteria, worsening liver fibrosis and inflammation.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

In this study, we developed a non-enzymatic electrochemical hydrogen peroxide (H₂O₂) sensor based on a reduced graphene oxide/platinum nanoparticle/ferrocene-tyramine/poly(o-phenylenediamine) (rGO/Pt NPs/Fc-Tyr/POPD) nanocomposite. H₂O₂, although not a tumor-specific biomarker, is an important reactive oxygen species associated with oxidative stress in cancer-related systems. The proposed sensing platform integrates the high conductivity of rGO, the electrocatalytic activity of Pt NPs, the TSA-derived Fc-Tyr deposition strategy, and the anti-interference properties of POPD. The sensor exhibited two wide linear detection ranges (5.0 µM-570 µM and 570 µM-10.5 mM), a low detection limit of 1.18 µM, and a rapid response time of less than 5 s. In addition, the sensor demonstrated satisfactory selectivity, reproducibility, and stability. Compared to previously reported rGO/Pt-based H₂O₂ sensors, the present platform introduces a TSA-derived Fc-Tyr deposition strategy to facilitate interfacial electron transfer and increase the density of redox-active species. The sensor was successfully applied to monitoring H₂O₂ changes in cultured cancer cells and ex vivo tumor tissue-derived samples under chemically stimulated oxidative conditions. These findings suggest that the proposed system may provide a useful tool for investigating oxidative-stress-associated biological processes and electrochemical H₂O₂ determination.\n\nID: 42083198\nTitle: Squid cartilage-derived chondroitin sulfate from Uroteuthis chinensis: a novel marine prebiotic modulating gut microbiota and ameliorating ulcerative colitis.\nAbstract: This study evaluated the prebiotic potential of chondroitin sulfate (CS) derived from the cartilage of the squid Uroteuthis chinensis, and its protective effects against dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) in mice. Dietary intervention with squid-derived CS significantly attenuated characteristic UC symptoms, including body weight loss, colon shortening, and histopathological damage. Mechanistic analyses revealed that squid-derived CS exerted potent anti-inflammatory effects by downregulating key pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) and alleviated oxidative stress by enhancing colonic antioxidant capacity, as evidenced by increased activities of catalase (CAT) and superoxide dismutase (SOD) and reduced myeloperoxidase (MPO) activity. Integrated 16S rRNA gene sequencing and metabolomics analyses demonstrated that squid-derived CS profoundly restructured gut microbial community composition by enriching putative beneficial bacteria (e.g., Bifidobacterium, Clostridium, Blautia) while reducing opportunistic pathogens (e.g., Enterococcus, Sutterellaceae, Clostridia_UCG-014). This favorable microbial shift was accompanied by a reconfiguration of the intestinal metabolome, characterized by elevated production of beneficial short-chain fatty acids (SCFAs) and decreased levels of pro-inflammatory metabolites such as tyramine. Furthermore, squid-derived CS effectively enhanced intestinal barrier integrity by upregulating key tight junction proteins (ZO-1, occludin, claudin-1), thereby preventing bacterial lipopolysaccharide (LPS) translocation and associated liver injury, as indicated by reduced serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Collectively, these findings demonstrate that dietary squid-derived CS protects against UC by modulating gut microbiota composition to enrich beneficial taxa, restoring microbial metabolite homeostasis, reinforcing the intestinal epithelial barrier, and suppressing inflammatory responses and oxidative stress. This study provides the first evidence that squid-derived CS acts as a novel and promising marine prebiotic candidate for gut health promotion, highlighting its potential as a sustainable functional ingredient derived from processing waste for gut-health-promoting foods.\n\nID: 42061249\nTitle: Gut health in broiler chickens fed a mixture of Hermetia illucens and Tenebrio molitor meals: does it have a key role in shaping bird performance?\nAbstract: Insect meals are promising sustainable protein sources for poultry, but comprehensive insights into their effects on gut health and growth performance are lacking. This study is the first to elucidate relationships between gut health parameters and performance in broilers fed Hermetia illucens (HI) and Tenebrio molitor (TM) meals at 5% or 10% inclusion levels, singly or in a 1:1 combination. A 37-day trial used 420 male Ross 308 chicks randomly allocated to seven treatments: control (C), HI5 (5% HI), HI10 (10% HI), TM5 (5% TM), TM10 (10% TM), MIX5 (5% MIX), and MIX10 (10% MIX). By integrating intestinal histomorphometry, mucin histochemistry, multi-organ histopathology, and multi-omics cecal microbiome characterization, we identified key structural, microbial, and metabolic biomarkers associated with performance variations (false discovery rate [FDR]<0.05 and P < 0.05 for microbiome and histomorphology, respectively). High-performing groups (MIX5, TM5) showed microbiomes enriched in short-chain fatty acid-producing bacteria (Veillonellaceae, Butyricicoccus, Limosilactobacillus crispatus), positively correlated with ADG and ADFI (FDR<0.05) and negatively correlated with FCR (FDR<0.05). Favorable metabolomic profiles (increased dopamine, tyramine, malic and orotic acids; reduced 3-deoxyglucosone, hexanoylcarnitine [FDR<0.05]) and preserved balance between neutral (positively correlated with BW and ADFI [P < 0.05]) and acidic mucins (positively correlated with BW, ADFI and ADG, and negatively correlated with FCR [P < 0.05]) were also observed. Low-performing groups (MIX10, HI10) displayed microbiomes dominated by Ruminococcaceae, Alistipes, and l-Eubacterium (negatively correlated with FCR and associated with purine metabolism alterations [FDR<0.05]), alongside worsened morphology (tendency for reduced villus height in MIX10 [P = 0.07], positively and negatively correlated with ADG and FCR, respectively [P < 0.05], and thinner mucosal/muscular layers [P < 0.05]) and decreased neutral mucins (P < 0.05). TM10 maintained unaffected growth performance via beneficial taxa (Limosilactobacillus crispatus, Tyzzerella), and reduced Campylobacter jejuni and antimicrobial resistance genes (FDR<0.05).

In conclusion, specific taxa (Butyricicoccus, Veillonellaceae, Limosilactobacillus crispatus), metabolites (dopamine, tyramine, malic and orotic acids), and mucosal features (villus height, mucin composition) were identified as biomarkers of optimal performance in insect-fed broilers.\n\nID: 41330669\nTitle: Split biosensor based on nano-enzymatic ferrocene-tyramine deposition reaction for detection of SMP30 antibody.\nAbstract: The tumor-associated autoantibody against senescence marker protein-30 (SMP30) serves as a critical serum biomarker for the early detection of hepatocellular carcinoma (HCC), enabling rapid and non-invasive cancer diagnosis and monitoring. However, the accurate detection of the SMP30 antibody remains challenging due to the complex composition of blood and the heterogeneity of circulating antibodies. This study introduces a highly sensitive and straightforward method for SMP30 antibody detection, utilizing a graphene oxide-Hemin (GO-Hemin) composite nano-mimetic enzyme in combination with ferrocenyl-tyramine (Fc-Tyr)-mediated tyramine signal amplification (TSA) within microtiter wells. A solid-phase protein with high affinity selectively captures the SMP30 antibody, while the target is identified via nano-mimetic enzyme labeling of a secondary antibody. The subsequent nano-enzymatic reaction facilitates the deposition of Fc-Tyr, generating a strong electrochemical signal. The biosensor achieves high sensitivity through enhanced electrochemical transduction and minimal spatial resistance at the electrode interface. By integrating immunocapture specificity with electrochemical amplification, this approach enables high-throughput analysis in clinical applications. Experimental results demonstrate that this biosensor can detect smp30 antibodies at concentrations as low as 0.1086 ng/mL, with a detection range spanning 0.1 ng/mL to 1 μg/mL. Analysis of authentic serum samples confirmed that when combined with ELISA, the sensor accurately measured SMP30 antibody levels in serum samples from clinical hepatocellular carcinoma patients. The results demonstrated consistent detection outcomes with recovery rates ranging from 93 % to 104 % and relative standard deviations (RSD) between 1.2 % and 3.7 %. This platform provides a practical and efficient tool for detecting SMP30 antibodies and holds broader application potential in tumor marker monitoring and cancer diagnosis.\n\nID: 41299593\nTitle: Gut microbial tyramine facilitates intestinal damage and metabolic dysfunction-associated steatotic liver disease development.\nAbstract: Emerging evidence indicates that gut microbiota and intestinal injury are crucial in pediatric metabolic dysfunction-associated steatotic liver disease (MASLD), yet the role of key gut microbial metabolites such as tyramine in pediatric MASLD remains largely unknown. In this study, we aimed to explore the role of gut microbial tyramine in intestinal damage and MASLD development in children. We investigated the functions and mechanisms of previously isolated Enterococcus faecium B6 (E. faecium B6) and its derived tyramine in a mice model of intestinal injury and MASLD development. An integrative analysis of transcriptomics and proteomics was performed on mouse liver to explore the molecular mechanisms of tyramine in MASLD progression. Targeted metabolomics was performed using fecal samples from a hospital-based population (27 MASLD cases and 27 matched controls) to measure tyramine levels. The association of serum tyramine and MASLD risk was then validated in a school-based population, using serum samples of 294 children in the MASLD group and 235 controls. E. faecium B6 and its metabolite tyramine significantly disrupted the intestinal barrier and increased intestinal permeability in mice. Tyramine supplementation promoted MASLD-related metabolic phenotype in mice. Multi-omics analysis indicated that the PPAR signaling pathway played an important role in the molecular mechanisms. Tyramine contributed to lipid accumulation mainly by increasing lipid synthesis and lipid uptake but reducing the β-oxidation processes in the mouse liver, as shown by real-time quantitative polymerase chain reaction and western blot. Furthermore, we demonstrated from the hospital-based cohort that tyramine concentration was significantly higher in the MASLD group than in the control group. Consistently, the school-based cohort demonstrated a higher risk of MASLD in the high-tyramine group compared to the low-tyramine group, with adjusted odds ratios (ORs) and 95% confidence intervals (CIs) of 3.65 (95% CI: 2.66-4.32). These results demonstrated that gut microbial tyramine effectively induced intestinal damage and facilitated MASLD development in mice. Tyramine was positively associated with the risk of MASLD in children. This study offered mechanistic insights into the pathogenesis of MASLD and opened therapeutic opportunities for such metabolic diseases.\n\nID: 40394473\nTitle: Modulating autism spectrum disorder pathophysiology using a trace amine-focused approach: targeting the gut.\nAbstract: Autism spectrum disorder (ASD) affects approximately 1% of the population directly, but also a much higher proportion (family and caregivers) indirectly. Although ASD is characterized by high prevalence of anxiety and poor gastrointestinal health, current treatment strategies are mainly focused on neurological symptomatic treatment, with little to no attention to gut health. Furthermore, many psychiatric drugs used for management of secondary neurological symptoms, are known to exacerbate gut health issues and neurological dysregulation across the gut-brain axis.Trace amines are neurotransmitter-like substances synthesized endogenously in the human brain - in trace amounts - but also in high abundance by the microbiome. Emerging evidence suggests dysregulation of the trace amine system in ASD. Since trace aminergic signalling is central to regulatory system homeostasis, we hypothesize targeting this system in the ASD context. Given the various sources of trace amines, we suggest that normalization of functional dysbiosis in terms of trace aminergic signalling - rather than microbial compositional dysbiosis - should be a focus in medicines development. In addition, a holistic consideration including also other factors at play in determining trace aminergic signalling outcome - such as receptor binding, enzymatic role players, etc. - is required to fully elucidate and therapeutically modify the pathophysiology of regulatory systems implicated in ASD.This review firstly provides a brief overview of trace amine dysregulation in ASD for context. Secondly, we formulate our hypothesis on how this may therapeutically address symptomology, with consideration of cellular and molecular mechanism interplay across the gut-brain axis. Finally, we provide a critical assessment of advances in therapeutics development and drug re-purposing, gaps in knowledge and priorities for medicines development going forward.\n\nID: 40362077\nTitle: Preliminary Multi-Omics Insights into Green Alternatives to Antibiotics: Effects of Pulsatilla chinensis, Acer truncatum, and Clostridium butyricum on Gut Health and Metabolic Regulation in Chickens.\nAbstract: Antibiotic resistance has become a global health concern, driving the need for sustainable alternatives in animal husbandry. This study explores the potential of natural feed additives as a viable solution to enhance poultry growth and health while reducing reliance on antibiotics. Chinese herbal medicines and probiotics have been widely studied as green, healthy, and safe antibiotic alternatives in livestock and poultry production. A total of 120 chickens were randomly divided into four groups: a control group and three treatment groups supplemented with 1% Pulsatilla chinensis powder, 3% fresh Acer truncatum, or 1% Clostridium butyricum. The results showed that Pulsatilla chinensis powder significantly increased gamma-glutamylcysteine (p < 0.05), UDP-N-acetylglucosamine (p < 0.05), tyramine (p < 0.01), and leucine (p < 0.05). Acer truncatum notably altered cecal metabolites, including L-tyrosine (p < 0.05), α-ketoisovaleric acid (p < 0.01), myristoleic acid (p < 0.01), glutathione (p < 0.05), and PGA1 (p < 0.05). Clostridium butyricum modified cecal metabolites such as L-glutamine (p < 0.05), riboflavin (p < 0.05), L-Carnitine (p < 0.05), ergocalciferol (p < 0.01), and α-tocotrienol (p < 0.05).\n\nID: 40294666\nTitle: p-Synephrine ameliorates non-alcoholic fatty liver disease by regulating liver-adipose axis via AMPK/NF-kappa B pathway.\nAbstract: Citrus aurantium L. var. amara Engl. is a folk medicine and dietary supplement popularly used in alleviating indigestion due to food retention and obesity. p-Synephrine, a principal proto-alkaloid in Citrus aurantium L. var. amara Engl., is extensively utilized due to its numerous benefits, particularly its potential to ameliorate obesity. Previous studies of our research demonstrated that p-synephrine had the potential to alleviate insulin resistance (IR) and liver lipid accumulation caused by high-fat diet (HFD), as well as enlargement of cells in adipose tissue. However, the effects of p-synephrine in ameliorating non-alcoholic fatty liver disease (NAFLD) were still unclear. To explore the effects of p-synephrine on HFD-induced NAFLD and its mechanisms. NAFLD mice were developed by HFD feeding and treated with p-synephrine once a day for 21 weeks. The protective effects of p-synephrine against NAFLD and its mechanisms were evaluated by OGTT, ITT, biochemical index measurements, H&E, immunofluorescence, Sirius red staining, oil red O staining, immunohistochemistry, RT-qPCR, Western blot, network pharmacology, and molecular docking assays. The results of network pharmacology suggested that AMPK-α1 might be the core target, and AMPK and insulin signaling pathways might be the key regulatory pathways of p-synephrine to alleviate NAFLD. Molecular docking confirmed AMPK-α1 as a probable direct molecular target. p-Synephrine significantly reduced HFD-induced weight gain of the body, liver, and iWAT. It improved glucose tolerance, insulin tolerance and lipid metabolism disorders caused by HFD. Serum levels of NO, TNF-α, and IL-6 in NAFLD mice were suppressed. AST, ALT, and HYP levels in serum and liver were inhibited. Morphological observation showed p-synephrine alleviated hepatic steatosis and fibrosis. p-Synephrine administration also significantly inhibited hepatic de novo lipogenesis (DNL), as evidenced by its regulation of non-esterified fatty acid (NEFA) and TG contents, as well as SREBP-1c, FASN, and ACC1 mRNA expression levels. p-Synephrine also reversed HFD-induced histopathological changes in iWAT, promoted iWAT browning by increasing UCP1 and PGC-1α expression. Simultaneously, p-synephrine intervention markedly increased phosphorylation levels of IRS-1, PI3K, and Akt, and protein expression of GLUT-4 in iWAT and liver. Expression of TNF-α, IL-6, and IL-1β and NF-κB activation in iWAT and liver were attenuated through the treatment of p-synephrine. Further assays showed that p-synephrine intervention potently regulated AMPK pathway in iWAT and liver of mice. This investigation proposed that p-synephrine had the potential to ameliorate HFD-induced NAFLD by regulating liver-adipose axis through AMPK/NF-κB pathway.\n\nID: 40284247\nTitle: Selective Influence of Hemp Fiber Ingestion on Post-Exercise Gut Permeability: A Metabolomics-Based Analysis.\nAbstract: Objectives: This study investigated the effects of 2-week ingestion of hemp fiber (high and low doses) versus placebo bars on gut permeability and plasma metabolite shifts during recovery from 2.25 h intensive cycling. Hemp hull powder is a rich source of two bioactive compounds, N-trans-caffeoyl tyramine (NCT) and N-trans-feruloyl tyramine (NFT), with potential gut health benefits. Methods: The study participants included 23 male and female cyclists. A three-arm randomized, placebo-controlled, double-blind, crossover design was used with two 2-week supplementation periods and 2-week washout periods. Supplement bars provided 20, 5, or 0 g/d of hemp hull powder. Participants engaged in an intensive 2.25 h cycling bout at the end of each of the three supplementation periods. Five blood samples were collected before and after supplementation (overnight fasted state), and at 0 h-, 1.5 h-, and 3 h-post-exercise. Five-hour urine samples were collected pre-supplementation and post-2.25 h cycling after ingesting a sugar solution containing 5 g of lactulose, 100 mg of 13C mannitol, and 1.9 g of mannitol in 450 mL of water. An increase in the post-exercise lactulose/13C mannitol ratio (L:13CM) was used as the primary indicator of altered gut permeability. Other outcome measures included muscle damage biomarkers (serum creatine kinase, myoglobin), serum cortisol, complete blood cell counts, and shifts in plasma metabolites using untargeted metabolomics. Results: No trial differences were found for L:13CM, cortisol, blood cell counts, and muscle damage biomarkers. Orthogonal partial least-squares discriminant analysis (OPLSDA) showed distinct trial differences when comparing high- and low-dose hemp fiber compared to placebo supplementation (R2Y = 0.987 and 0.995, respectively). Variable Importance in Projection (VIP) scores identified several relevant metabolites, including 3-hydroxy-4-methoxybenzoic acid (VIP = 1.9), serotonin (VIP = 1.5), 5-hydroxytryptophan (VIP = 1.4), and 4-methoxycinnamic acid (VIP = 1.4). Mummichog analysis showed significant effects of hemp fiber intake on multiple metabolic pathways, including alpha-linolenic acid, porphyrin, sphingolipid, arginine and proline, tryptophan, and primary bile acid metabolism. Conclusions: Hemp fiber intake during a 2-week supplementation period did not have a significant effect on post-exercise gut permeability in cyclists (2.25 h cycling bout) using urine sugar data. On the contrary, untargeted metabolomics showed that the combination of consuming nutrient-rich hemp fiber bars and exercising for 135 min increased levels of beneficial metabolites, including those derived from the gut in healthy cyclists.\n\nID: 39266876\nTitle: MCT4 is an independent prognostic factor and affects immune cell infiltration in patients with colorectal liver oligometastases.\nAbstract: Monocarboxylate transporter 4 (MCT4) is a novel biomarker related to the level of immune cell infiltration, but its impact on tumor immune microenvironment (TIME) of colorectal liver oligometastases (CLO) remains unclear. The aim of this study was to assess MCT4 expression in primary tumor and liver oligometastases, investigate its impact on immune cell infiltration and its prognostic value for CLO patients undergoing liver resection. We retrospectively selected 135 CLO patients who underwent curative liver resection between June 1999 and December 2016, and samples included 74 primary tumor tissues and 122 liver metastases. Immunohistochemistry (IHC) was performed to detect MCT4 expression in paraffin-embedded specimens and tyramine signal amplification (TSA) was used to detect the density of tumor-infiltrating lymphocytes, including CD3 + , CD8 + and Foxp3 + . Recurrence-free survival (RFS) and overall survival (OS) were analyzed using the Kaplan-Meier method and log-rank test, and independent prognostic factors were identified with Cox regression modeling. Survival analysis indicated that CLO patients with low MCT4 expression had better 3-year RFS and 3-year OS rates than those with high MCT4 expression. Multivariate analysis indicated that high MCT4 expression was independently associated with poor RFS and OS. High MCT4 expression was associated with a lower number of intratumoral CD3 + /CD8 + T cells and was associated with higher Foxp3 + T cells infiltration. Patients with low MCT4 expression and high levels of differential immune infiltration had longer survival. MCT4 overexpression was associated with an unfavorable prognosis in patients with CLO and MCT4 expression level had an impact on intratumoral immune infiltration degree. A novel parameter that combined MCT4 expression level and differential immune infiltration level was constructed to stratify patients with CLO into different risk groups.\n\nID: 38738766\nTitle: Cultivated Enterococcus faecium B6 from children with obesity promotes nonalcoholic fatty liver disease by the bioactive metabolite tyramine.\nAbstract: Gut microbiota plays an essential role in nonalcoholic fatty liver disease (NAFLD). However, the contribution of individual bacterial strains and their metabolites to childhood NAFLD pathogenesis remains poorly understood. Herein, the critical bacteria in children with obesity accompanied by NAFLD were identified by microbiome analysis. Bacteria abundant in the NAFLD group were systematically assessed for their lipogenic effects. The underlying mechanisms and microbial-derived metabolites in NAFLD pathogenesis were investigated using multi-omics and LC-MS/MS analysis. The roles of the crucial metabolite in NAFLD were validated in vitro and in vivo as well as in an additional cohort. The results showed that Enterococcus spp. was enriched in children with obesity and NAFLD. The patient-derived Enterococcus faecium B6 (E. faecium B6) significantly contributed to NAFLD symptoms in mice. E. faecium B6 produced a crucial bioactive metabolite, tyramine, which probably activated PPAR-γ, leading to lipid accumulation, inflammation, and fibrosis in the liver. Moreover, these findings were successfully validated in an additional cohort. This pioneering study elucidated the important functions of cultivated E. faecium B6 and its bioactive metabolite (tyramine) in exacerbating NAFLD. These findings advance the comprehensive understanding of NAFLD pathogenesis and provide new insights for the development of microbe/metabolite-based therapeutic strategies.\n\nID: 38623209\nTitle: Beneath the rind: A review on the remarkable health benefits and applications of the wood apple fruit.\nAbstract: Limonia acidissima Groff, commonly referred to as the Wood apple, is a tropical fruit belonging to Rutaceae family. Indigenous to Sri Lanka, India, and Myanmar, it is extensively cultivated throughout Southeast Asia. This fruit holds a profound historical significance in traditional medicine due to its exceptional nutritional and therapeutic attributes. Wood apple pulp is significantly abundant in β-carotene, a precursor to vitamin A, and contains a substantial amount of vitamin B, including riboflavin and thiamine, as well as trace amounts of ascorbic acid (vitamin C). Moreover health-benefitting properties associated with L. acidissima, such as, antioxidant, hepatoprotective, antimicrobial, neuroprotective, antidiabetic, anti-inflammatory, anti-spermatogenic, analgesic, antiulcer, and antihyperlipidemic properties, are attributed to a diverse range of phytochemicals. These encompass polyphenolic compounds, saponins, phytosterols, tannins, triterpenoids, coumarins, amino acids, tyramine derivatives, and vitamins. From the findings of the various studies, it was observed that wood apple fruit shows significant anticancer activity by inhibiting the proliferation of cancer. Furthermore, wood apple finds wide-ranging commercial applications in the formulation of ready-to-serve beverages, syrups, jellies, chutneys, and various other food products. In summary, this review highlights the nutritional and phytochemical constituents of wood apple, depicts its antioxidant, anti-inflammatory, and anti-diabetic capabilities, and explores its potential in value-added product development. Nevertheless, it is crucial to acknowledge that the molecular mechanisms supporting these properties remain an underexplored domain. To ensure the safe integration of wood apple fruit into the realms of the food, cosmetics, and pharmaceutical sectors, rigorous clinical trials, including toxicity assessments, are required. These endeavors hold the potential to promote innovation and contribute significantly to both research and industrial sectors.\n\nID: 38588628\nTitle: Hepatocellular carcinoma biomarkers screening based on hydrogel photonic barcodes with tyramine deposition amplified ELISA.\nAbstract: Hepatocellular carcinoma (HCC), as one of the most lethal cancers, significantly impacts human health. Attempts in this area tends to develop novel technologies with sensitive and multiplexed detection properties for early diagnosis. Here, we present novel hydrogel photonic crystal (PhC) barcodes with tyramine deposition amplified enzyme-linked immunosorbent assay (ELISA) for highly sensitive and multiplexed HCC biomarker screening. Because of the abundant amino groups of acrylic acid (AA) component, the constructed hydrogel PhC barcodes with inverse opal structure could facilitate the loading of antibody probes for subsequent detection of tumor markers. By integrating tyramine deposition amplified ELISA on the barcode, the detection signal of tumor markers has been enhanced. Based on these features, it is demonstrated that the hydrogel PhC barcodes with tyramine deposition amplified ELISA could realize highly sensitive and multiplexed detection of HCC-related biomarkers. It was found that this method is flexible, sensitive and accurate, suitable for multivariate analysis of low abundance tumor markers and future cancer diagnosis. These features make the newly developed PhC barcodes an innovation platform, which possesses tremendous potential for practical application of low abundance targets.\n\nID: 38518452\nTitle: Identification of metabolites produced by six gut commensal Bacteroidales strains using non-targeted LC-MS/MS metabolite profiling.\nAbstract: As the most abundant gram-negative bacterial order in the gastrointestinal tract, Bacteroidales bacteria have been extensively studied for their contribution to various aspects of gut health. These bacteria are renowned for their involvement in immunomodulation and their remarkable capacity to break down complex carbohydrates and fibers. However, the human gut microbiota is known to produce many metabolites that ultimately mediate important microbe-host and microbe-microbe interactions. To gain further insights into the metabolites produced by the gut commensal strains of this order, we examined the metabolite composition of their bacterial cell cultures in the stationary phase. Based on their abundance in the gastrointestinal tract and their relevance in health and disease, we selected a total of six bacterial strains from the relevant genera Bacteroides, Phocaeicola, Parabacteroides, and Segatella. We grew these strains in modified Gifu anaerobic medium (mGAM) supplemented with mucin, which resembles the gut microbiota's natural environment. Liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based metabolite profiling revealed 179 annotated metabolites that had significantly differential abundances between the studied bacterial strains and the control growth medium. Most of them belonged to classes such as amino acids and derivatives, organic acids, and nucleot(s)ides. Of particular interest, Segatella copri DSM 18205 (previously referred to as Prevotella copri) produced substantial quantities of the bioactive metabolites phenylethylamine, tyramine, tryptamine, and ornithine. Parabacteroides merdae CL03T12C32 stood out due to its ability to produce cadaverine, histamine, acetylputrescine, and deoxycarnitine. In addition, we found that strains of the genera Bacteroides, Phocaeicola, and Parabacteroides accumulated considerable amounts of proline-hydroxyproline, a collagen-derived bioactive dipeptide. Collectively, these findings offer a more detailed comprehension of the metabolic potential of these Bacteroidales strains, contributing to a better understanding of their role within the human gut microbiome in health and disease.\n\nID: 38421203\nTitle: New aspects characterizing non-obese NAFLD by the analysis of the intestinal flora and metabolites using a mouse model.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) is a major public health problem due to the high incidence affecting approximately one-third of the world's population. NAFLD is usually linked to obesity and excessive weight. A subset of patients with NAFLD expresses normal or low body mass index; thus, the condition is called non-obese NAFLD or lean NAFLD. However, patients and healthcare professionals have little awareness and understanding of NAFLD in non-obese individuals. Furthermore, preclinical results from non-obese animal models with NAFLD are unclear. Gut microbiota and their metabolites in non-obese/lean-NAFLD patients differ from those in obese NAFLD patients. Therefore, we analyzed the biochemical indices, intestinal flora, and intestinal metabolites in a non-obese NAFLD mouse model established using a methionine-choline-deficient (MCD) diet. The significantly lean MCD mice had a remarkable fatty liver with lower serum triglyceride and free fatty acid levels, as well as higher alanine transaminase and aspartate transaminase levels than normal mice. 16S RNA sequencing of fecal DNA showed that the overall richness and diversity of the intestinal flora decreased in MCD mice, whereas the Firmicutes:Bacteroidota ratio was increased. g_Tuzzerella, s_Bifidobacterium pseudolongum, and s_Faecalibaculum rodentium were the predominant species in non-obese NAFLD mice. Fecal metabolomics using liquid chromatography-tandem mass spectrometry revealed the potential biomarkers for the prognosis and diagnosis of non-obese NAFLD, including high levels of tyramine glucuronide, 9,12,13-TriHOME, and pantetheine 4'-phosphate, and low levels of 3-carbamoyl-2-phenylpropionaldehyde, N-succinyl-L,L-2,6-diaminopimelate, 4-methyl-5-thiazoleethanol, homogentisic acid, and estriol. Our findings could be useful to identify and develop drugs to treat non-obese NAFLD and lean NAFLD. Patients and healthcare professionals have little awareness and understanding of NAFLD in non-obese individuals. In fact, about 40% of people with NAFLD worldwide are non-obese, and nearly one-fifth are lean. Lean NAFLD unfortunately may be unnoticed for years and remains undetected until hepatic damage is advanced and the prognosis is compromised. This study focused on the lean NAFLD, screened therapeutic agents, and biomarkers for the prognosis and diagnosis using MCD-induced male C57BL/6J mice. The metabolites tyramine glucuronide, 9,12,13-TriHOME, and pantetheine 4'-phosphate, together with the predominant flora including g_Tuzzerella, s_Bifidobacterium pseudolongum, and s_Faecalibaculum rodentium, were specific in non-obese NAFLD mice and might be used as targets for non-obese NAFLD drug exploration. This study is particularly significant for non-obese NAFLDs that need to be more actively noticed and vigilant.\n\nID: 37499843\nTitle: Traditional uses, phytochemistry, pharmacology, processing methods and quality control of Lindera aggregata (Sims) Kosterm: A critical review.\nAbstract: Dried root tubers of L.aggregata have been widely used in Chinese herbal medicine for thousands of years to promote qi, relieve pain, warm kidney, and disperse cold. This review aims to assess the research progress of L.aggregata, to comprehensively understand its development status, to point out the shortcomings of the existing researches, and to provide reference for further research on L.aggregata. By searching various databases for literatures on \"Lindera aggregata\", \"Linderae Radix\" and \"Lindera strychnifolia\", as well as relevant textbooks and digital documents, an overall and critical review of the subject was conducted. Through phytochemical studies on different parts of L.aggregata, about 260 compounds were isolated, including flavonoids, alkaloids, terpenes, volatile oils, and other compounds. A large number of in vivo and in vitro studies have shown that L.aggregata has a plethora of pharmacological effects such as anti-cancer, anti-arthritis, anti-bacterial, anti-oxidation, anti-diabetic nephropathy, hepatoprotective, lipid-lowering effect and so on. While the pharmacological effects of L.aggregata have been confirmed, most studies only use simple in vitro cell lines or animal disease models to evaluate their pharmacological activities. Therefore, future research should be conducted in a more comprehensive clinical manner. Further pharmacological research is also necessary to fully clarify the action mechanism of L.aggregata. It is also interesting to note that L.aggregata is often used to treat frequent urination in ancient times, but its molecular basis and mechanism of action are still unclear, and systematic studies are lacking. In terms of quality control, the source of L.aggregata is single, mostly wild, and the main medicinal part of L.aggregata is the tuber, while the yield of straight root is large. Therefore, further attention should be paid to the rapid propagation technology of L.aggregata and whether straight root can be included in medicinal use. It is also worth thinking whether sulfur-fumigation is necessary for preserving L.aggregata. As vinegar-processing is a common processing method for L. aggregata, the mechanism of such processing method remains to be investigated. In addition, in-depth research on the pharmacokinetics and long-term toxicity of L.aggregata is necessary to ensure its efficacy and safety.\n\nID: 36899958\nTitle: Fermented Soybean Paste Attenuates Biogenic Amine-Induced Liver Damage in Obese Mice.\nAbstract: Biogenic amines are cellular components produced by the decarboxylation of amino acids; however, excessive biogenic amine production causes adverse health problems. The relationship between hepatic damage and biogenic amine levels in nonalcoholic fatty liver disease (NAFLD) remains unclear. In this study, mice were fed a high-fat diet (HFD) for 10 weeks to induce obesity, presenting early-stage of NAFLD. We administered histamine (20 mg/kg) + tyramine (100 mg/kg) via oral gavage for 6 days to mice with HFD-induced early-stage NAFLD. The results showed that combined histamine and tyramine administration increased cleaved PARP-1 and IL-1β in the liver, as well as MAO-A, total MAO, CRP, and AST/ALT levels. In contrast, the survival rate decreased in HFD-induced NAFLD mice. Treatment with manufactured or traditional fermented soybean paste decreased biogenically elevated hepatic cleaved PARP-1 and IL-1β expression and blood plasma MAO-A, CRP, and AST/ALT levels in HFD-induced NAFLD mice. Additionally, the biogenic amine-induced reduction in survival rate was alleviated by fermented soybean paste in HFD-induced NAFLD mice. These results show that biogenic amine-induced liver damage can be exacerbated by obesity and may adversely affect life conservation. However, fermented soybean paste can reduce biogenic amine-induced liver damage in NAFLD mice. These results suggest a beneficial effect of fermented soybean paste on biogenic amine-induced liver damage and provide a new research perspective on the relationship between biogenic amines and obesity.\n\nID: 36680969\nTitle: An electrochemical immunosensor for the detection of Glypican-3 based on enzymatic ferrocene-tyramine deposition reaction.\nAbstract: An ultrasensitive electrochemical immunosensor based on signal amplification of the deposition of the electroactive ferrocene-tyramine (Fc-Tyr) molecule, catalyzed by horseradish peroxidase (HRP), was constructed for the detection of the liver cancer marker Glypican-3 (GPC3). Functional electroactive molecule Fc-Tyr is reported to exhibit both the enzymatic cascade catalytic activity of tyramine signal amplification (TSA) and the excellent redox properties of ferrocene. In terms of design, the low matrix effects inherent in using the magnetic bead platforms, a quasi-homogeneous system, allowed capturing the target protein GPC3 without sample pretreatment, and loading HRP to trigger the TSA, which induced a large amount of Fc-Tyr deposited on the electrode surface layer by layer as a signal probe for the detection of GPC3. The concept of Fc-Tyr as an electroactive label was validated, GPC3 biosensor exhibited high selectivity and sensitivity to GPC3 in the range of 0.1 ng mL-1-1 μg mL-1. Finally, the sensor was used simultaneously with ELISA to assess GPC3 levels in the serum of clinical liver cancer patients, and the results showed consistency, with a recovery of 98.33-105.35% and a relative standard deviation (RSD) of 4.38-8.18%, providing a theoretical basis for achieving portable, rapid and point of care testing (POCT) of tumor markers.\n\nID: 36263407\nTitle: Dietary citrus pectin drives more ileal microbial protein metabolism and stronger fecal carbohydrate fermentation over fructo-oligosaccharide in growing pigs.\nAbstract: Fructo-oligosaccharide (FOS) and pectin are known soluble dietary fibers and can influence gut microbiota and consequently modulate gut health. To understand the differential impact patterns of pectin vs. FOS in modulating gut microbiota in the small and large intestine, an ileal-cannulated pig model was adopted to compare the temporal and spatial effects of FOS and citrus pectin (CP) on the gut microbiota. Sixteen terminal ileal-cannulated pigs were randomly divided into 2 groups and fed with a standard diet supplemented with either 3% FOS or 3% CP for 28 d. The CP group and FOS group showed different microbial composition, especially in the feces, with time and location as major factors affecting microbiota in the CP group, and with only location contribution in the FOS group. In the feces, relative to the FOS group, the CP group showed higher abundance of Christensenellaceae R-7 group and Ruminococcaceae UCG-010 and lower abundance of Mitsuokella and Olsenella (adjusted P < 0.05), a higher level of short-chain fatty acids and a lower level of lactate at both d 14 and 25 (P < 0.05), and more copy numbers of genes encoding key enzymes related to propionate (mmdA) and butyrate (BCoAT) production and lactate utilization (LcdA) (P < 0.05), indicating a greater degree of microbial carbohydrate fermentation. In the ileum, as compared with FOS, CP increased the bacteria with high capability of fermenting amino acids, including Escherichia-Shigella and Klebsiella (adjusted P < 0.05), and the expression of enzymes responsible for amino acid fermentation (i.e. lysine decarboxylase), as well as the amino acid fermentation products (cadaverine and tyramine) (P < 0.05), indicating a greater degree of amino acid fermentation. Overall, our results highlight a differential dynamic impact of dietary CP vs. FOS on microbial composition and metabolism in the gut. The dietary CP has a stronger ability to promote microbial amino acid fermentation in the ileum and carbohydrate fermentation in the feces than FOS. These findings provide a new insight into the role of different fibers in gut nutrition and guidelines for the choice of fibers in manipulating gut health.\n\nID: 35850312\nTitle: Rooibos (Aspalathus linearis) alters secretome trace amine profile of probiotic and commensal microbes in vitro.\nAbstract: Aspalathus linearis (Burm.f.) R. Dahlgren (rooibos) tea is anecdotally renowned for its calming effect in the context of gastrointestinal discomfort, but little scientific support is available to elucidate potential mechanisms of action. Enhancement of dietary polyphenol content to improve gut health via prebiotic-like modulation of the gut microbiota has gained significant research interest. Given the known high polyphenol content of rooibos, rooibos tea may potentially exert a prebiotic effect in the gut to facilitate an improvement in chronic inflammatory gastrointestinal conditions. This study aimed to determine the prebiotic or health-modulating potential of rooibos tea in terms of its effect on gut microbial growth and secretome trace amine composition, as well as to determine how differential rooibos processing alters this activity. Three rooibos preparations (green and fermented leave aqueous extracts, as well as a green leaf ethanol extract) were compared in terms of their phenolic composition (qTOF-LC/MS). Moreover, the effect of rooibos exposure on growth and secretome trace amine levels of probiotic and commensal microbes were assessed (LC/MS). In addition, given the known female bias prevalent for many gastrointestinal disorders, experiments were conducted in the absence and presence of estradiol. Polyphenolic composition of rooibos was drastically reduced by fermentation. Aqueous extracts of both green and fermented rooibos improved microbial growth, although fermented rooibos had the most pronounced effect (p < 0.01). In terms of secretome trace amine profile, both aqueous extracts of rooibos seemed to facilitate increased putrescine secretion (p < 0.0001) and decreased tryptamine production (p < 0.0001). Estradiol seemed to suppress trace amine secretion by bacteria (Lactobacillus plantarum, Lactobacillus reuteri and Enterococcus mundtii) but increased it in yeast (Saccharomyces boulardii). Rooibos altered gut probiotic and commensal microbial growth and secretome trace amine profiles in vitro, suggesting it has potential to modulate gut microbial composition and functionality as a prebiotic. Current data suggest that these effects are highly dependent on raw material processing. Finally, rooibos may be able to prevent estradiol-associated alterations in trace amine profile, which may have important implications for patient management in female-predominant gastrointestinal disorders.\n\nID: 35694542\nTitle: The Microbiota and It's Correlation With Metabolites in the Gut of Mice With Nonalcoholic Fatty Liver Disease.\nAbstract: In recent years, nonalcoholic fatty liver disease (NAFLD) has become the most common liver disease in the world. As an important model animal, the characteristics of gut microbiota alteration in mice with NAFLD have been studied but the changes in metabolite abundance in NAFLD mice and how the gut microbiota affects these intestinal metabolites remain unclear. In this experiment, a mouse model for NAFLD was established by a high-fat diet. The use of 16S rDNA technology showed that while there were no significant changes in the alpha diversity in the cecum of NAFLD mice, the beta diversity changed significantly. The abundance of Blautia, Unidentified-Lachnospiraceae, Romboutsia, Faecalibaculum, and Ileibacterium increased significantly in NAFLD mice, while Allobaculum and Enterorhabdus decreased significantly. Amino acids, lipids, bile acids and nucleotide metabolites were among the 167 significantly different metabolites selected. The metabolic pathways of amino acids, SFAs, and bile acids were significantly enhanced, while the metabolic pathways of PUFAs, vitamins, and nucleotides were significantly inhibited. Through correlation and MIMOSA2 analysis, it is suggested that gut microbiota does not affect the changes of lipids and bile acids but can reduce thiamine, pyridoxine, and promote L-phenylalanine and tyramine production. The findings of this study will help us to better understand the relationship between gut microbiota and metabolites in NAFLD.\n\nID: 33289566\nTitle: Gut Microbiota-Derived Metabolite Signature in Suckling and Weaned Piglets.\nAbstract: The gut microbiota plays a key role in intestinal development at the suckling-to-weaning transition. The objective of this study was to analyze the production of metabolites by the gut microbiota in suckling and weaned piglets. We studied piglets raised in two separate maternity farms and weaned at postnatal day 21 in the same farm. The fecal metabolome (1H nuclear magnetic resonance) and the microbiota composition (16S rRNA gene amplicon sequencing) and its predicted functions (PICRUSt2) were analyzed in the same piglets during the suckling period (postnatal day 13) and 2 days after weaning (postnatal day 23). The relative concentrations of the bacterial metabolites methylamine, dimethylamine, cadaverine, tyramine, putrescine, 5-aminovalerate, succinate, and 3-(4-hydroxyphenylpropionate) were higher during the suckling period than after weaning. In contrast, the relative concentrations of the short-chain fatty acids acetate and propionate were higher after weaning than during the suckling period. The maternity of origin of piglets also influenced the level of some bacterial metabolites (propionate and isobutyrate). The fecal metabolome signatures observed in suckling and weaned piglets were associated with specific microbiota-predicted functionalities, structure, and diversity. Gut microbiota-derived metabolites, which are differentially abundant between suckling and weaned piglets (e.g., short-chain fatty acids and biogenic amines), are known to regulate gut health. Thus, identification of metabolome signatures in suckling and weaned piglets paves the way for the development of health-promoting nutritional strategies, targeting the production of bacterial metabolites in early life.\n\nID: 32628331\nTitle: Dietary supplementation with Bacillus subtilis DSM 32315 alters the intestinal microbiota and metabolites in weaned piglets.\nAbstract: The study was conducted to investigate the effects of dietary Bacillus subtilis (BS) DSM 32315 on the intestinal microbiota composition and metabolites of weaned pigs. Sixty-four piglets were allocated to two groups (control and BS), each group including eight replicates with four piglets. Dietary BS DSM 32315 increased (P < 0·05) the abundances of jejunal Leucobacter and Cupriavidus, ileal Thermus, Coprococcus and Bifidobacterium, as well as colonic Succiniclasticum; and increased the concentrations of ileal straight-chain fatty acids, colonic propionate, branched-chain fatty acids (BCFAs), and tyramine, but decreased (P < .05) the colonic indole concentration. The ileal and colonic microbial community structure tended to cluster into two groups. LEfSe analysis identified five microbial biomarkers in jejunum and eight biomarkers in ileum in the BS group, and three biomarkers in colon in the control group. The ileal Bifidobacterium abundance was positively correlated (P < 0·05) with isovalerate concentration, while the colonic Actinobacteria and Lactobacillus abundances were negatively correlated (P < 0·05) with indole concentration. These findings suggest that dietary supplementation with BS DSM 32315 could alter the diversity, composition, and metabolites of intestinal microbiota in weaned piglets. Weaned piglets are often accompanied with impaired gastrointestinal tract and intestinal disorder affecting their growth. This study demonstrated that dietary BS DSM 32315 presented a beneficial role in gut health via regulating intestinal microbiota composition and metabolites.\n\nID: 23328125\nTitle: Injectable hyaluronic acid-tyramine hydrogels incorporating interferon-α2a for liver cancer therapy.\nAbstract: We report an injectable hydrogel system that incorporates interferon-α2a (IFN-α2a) for liver cancer therapy. IFN-α2a was incorporated in hydrogels composed of hyaluronic acid-tyramine (HA-Tyr) conjugates through the oxidative coupling of Tyr moieties with hydrogen peroxide (H2O2) and horseradish peroxidase (HRP). IFN-α2a-incorporated HA-Tyr hydrogels of varying stiffness were formed by changing the H2O2 concentration. The incorporation of IFN-α2a did not affect the rheological properties of the hydrogels. The activity of IFN-α2a was furthermore well-maintained in the hydrogels with lower stiffness. Through the caspase-3/7 pathway in vitro, IFN-α2a released from HA-Tyr hydrogels inhibited the proliferation of liver cancer cells and induced apoptosis. In the study of the pharmacokinetics, a higher concentration of IFN-α2a was shown in the plasma of mice treated with IFN-α2a-incorporated hydrogels after 4h post injection, with a much higher amount of IFN-α2a delivered at the tumor tissue comparing to that of injecting an IFN-α2a solution. The tumor regression study revealed that IFN-α2a-incorporated HA-Tyr hydrogels effectively inhibited tumor growth, while the injection of an IFN-α2a solution did not demonstrate antitumor efficacy. Histological studies confirmed that tumor tissues in mice treated with IFN-α2a-incorporated HA-Tyr hydrogels showed lower cell density, with more apoptotic and less proliferating cells compared with tissues treated with an IFN-α2a solution. In addition, the IFN-α2a-incorporated hydrogel treatment greatly inhibited the angiogenesis of tumor tissues.\n\nID: 42418876\nTitle: Deciphering underground decarboxylase activity towards Nε-modified lysine derivatives in enterobacteria.\nAbstract: Thermal food processing generates diverse compounds interacting with the gut microbiota. Despite their abundance, the microbial turnover of diet-borne Nε-modified lysine derivatives remains largely unexplored. We demonstrate that the enterobacterial ornithine decarboxylase SpeC degrades the prevalent advanced glycation end product Nε-carboxymethyllysine (CML) to carboxymethylcadaverine via an underground activity (∼4 molecules/enzyme/min). This promiscuity extends to additional Nε-modified lysine derivatives - namely formylated (FmL), monomethylated (MML) and dimethylated (DML) lysine - yielding previously unknown biogenic amines (mono- and dimethylcadaverine, formylcadaverine). Functionally, SpeC enables Escherichia coli to utilize CML as a sole nitrogen source. In specific strains, this metabolism reinforces pH-stress responses, supporting survival under mild acidic conditions typical for the colon. Furthermore, SpeC orthologs are widespread across human gut genomes, correlating with geography, diet, and disease. Together, these findings suggest a potential diet-microbiome communication axis, linking the intake of modified dietary chemicals to microbial physiology and hypothesized host impacts.\n\nID: 42399364\nTitle: Sex-specific responses of finishing pigs to dietary protein restriction in nutrient utilization and nitrogen-related metabolites derived from gut microbiota.\nAbstract: This study was conducted to explore the effects of dietary protein restriction on growth performance, nutrient utilization, gut microbiota, and microbial metabolites in finishing pigs, as well as to elucidate potential sex-associated differences between gilts and barrows. A total of 36 gilts and 36 barrows at 110 days of age were allocated to six groups in a 3 × 2 factorial arrangement consisting of three dietary protein levels and two sexes. Dietary crude protein levels were 17%, 15%, and 13% during phase I, and 15%, 13%, and 11% during phase II. The whole feeding trial lasted 51 days. Overall, lowering dietary protein levels altered the digestibilities of crude protein, ether extract, calcium and phosphorus (P < 0.01), and exerted sex-specific influences on serum total protein and nitric oxide concentrations (P < 0.05). Among gut microbiota, five genera responded to protein restriction (P < 0.05), eight showed sex differences (P < 0.05), and six exhibited sex-specific responses to dietary protein levels (P < 0.05). Dietary protein restriction reduced gut microbiota-derived ammonia nitrogen and six of eight biogenic amines (P < 0.05); four of these metabolites differed between sexes (P < 0.05), and four showed protein × sex interactions (P < 0.05). The nitrogen-related metabolites were positively correlated with specific microbiota only in gilts (P < 0.05). In conclusion, dietary protein restriction induced sex-specific alterations in gut microbiota and nitrogen-associated metabolites in finishing pigs, and such metabolic responses were exclusively linked to microbiota changes in gilts but not in barrows.\n\nID: 42352465\nTitle: Cervicovaginal Microbiota and Biogenic Amine Metabolic Shifts in HPV-Associated Cervical Disease.\nAbstract: Background: Cervical cancer is primarily caused by the human papillomavirus (HPV), with persistent infections progressing to low- (LGSIL) and high-grade (HGSIL) lesions. Emerging evidence indicates that the cervicovaginal microbiota influences HPV persistence and disease progression, although the underlying metabolic mechanisms remain unclear. Therefore, we assessed the relationship between the cervicovaginal microbiota and the metabolic milieu in women with cervical dysplasia and HPV infections. Methods: We recruited 36 non-menopausal, non-pregnant women who were classified as negative, LGSIL, or HGSIL based on pathology and HPV results. Cervical swabs were collected for genomic DNA extraction to characterize bacterial communities using 16S rRNA sequencing and to perform HPV genotyping. Cervical lavages were collected for untargeted metabolomic profiling using Gas Chromatography-Mass Spectrometry. Integrative multiomic analysis was performed using the MIMOSA2 pipeline. Results: Although bacterial community structure was not different between groups, women with HGSIL had higher richness and exhibited a higher abundance of Prevotella bivia, Prevotella buccalis, and Lachnospiraceae G-9 oral taxon 924. Lesion-positive samples had shifts in tyramine and putrescine, biogenic amines linked to cancer development. Specifically, Pseudomonas was identified as a potential contributor to tyramine oxidation. Conclusions: Cervical lesions and HPV risk are associated with shifts in the cervicovaginal microbial metabolic milieu, highlighting the role of low-abundant anaerobic bacteria. Despite the small sample size, biogenic amines were associated with anaerobic taxa and microbial dysbiosis. These findings warrant further assessment of microbial-derived metabolites and their potential to promote tumor progression by driving a pro-inflammatory, metabolically altered microenvironment.\n\nID: 42283770\nTitle: Divergent Colorectal Cancer Risks Following Metabolic Bariatric Surgery: Anatomical Remodeling and the Genotoxic Microenvironment.\nAbstract: Metabolic bariatric surgery (MBS) reduces overall cancer incidence, yet colorectal cancer (CRC) risk diverges by procedure. Roux-en-Y gastric bypass (RYGB) has been associated with increased long-term CRC risk (HR 1.55 at 10-14 years), whereas sleeve gastrectomy (SG) shows no equivalent elevation, though shorter follow-up (mean 4.5 vs. 8.5 years) precludes definitive conclusions. This review develops a biologically plausible mechanistic framework for these divergent outcomes. RYGB-induced anatomical bypass and accelerated transit are proposed to drive distal substrate overload, with an associated shift of the colonic microbiome toward proteolytic fermentation. The proposed genotoxic luminal environment is characterized by convergent actions of secondary bile acids, tyramine, and hydrogen sulfide, compounded by butyrate depletion. By preserving gastrointestinal continuity, SG is hypothesized to avoid these alterations. These considerations support integrating baseline CRC risk into surgical selection and procedure-specific surveillance after RYGB.\n\nID: 42240953\nTitle: Phenotypic, Genomic, and In Vivo Characterization of a Host-Derived Limosilactobacillus fermentum RLF77 with Potential to Prevent Post-weaning Diarrhea in Rabbits.\nAbstract: Following the 2020 ban on antibiotic growth promoters in animal feed, diarrheal disease in weaned rabbits has become an increasingly important challenge for the rabbit industry. Due to their superior intestinal adaptability and colonization potential, host-derived probiotics are considered promising alternatives. In this study, Limosilactobacillus fermentum RLF77, a lactic acid bacterium, was isolated from the intestinal contents of healthy young rabbits. Strain RLF77 showed a favorable safety profile, including γ hemolysis, a negative indole reaction, and no production of biogenic amines. Furthermore, the strain exhibited strong tolerance to heat, acidic conditions, bile salts, and simulated gastrointestinal fluids, as well as broad antimicrobial activity against a range of enteric pathogens. It also displayed moderate cell surface hydrophobicity, auto-aggregation ability, and strong antioxidant activity. Whole genome sequencing revealed that RLF77 possesses a 2.31 Mbp genome enriched in genes involved in carbohydrate and amino acid metabolism, stress response, and oxidative defense. In addition, genome mining identified biosynthetic gene clusters putatively encoding enterolysin A. Oral administration in mice further supported the in vivo safety of RLF77 and significantly increased villus height and the villus height/crypt depth ratio. In an E. coli-challenged weaned rabbit model, dietary RLF77 supplementation improved growth performance, reduced diarrhea incidence, enhanced immune and antioxidant capacity, alleviated intestinal injury, and improved gut microbiota composition by increasing microbial richness and Akkermansiaceae abundance. Collectively, the host-derived strain L. fermentum RLF77 is a safe and promising probiotic candidate for improving intestinal health and preventing post-weaning diarrhea in rabbits.\n\nID: 42221754\nTitle: Functional fermented dairy products: a review of mechanisms, health potential, and technological challenges.\nAbstract: Fermented dairy products such as yoghurt, kefir and cheese are increasingly recognised as functional foods due to the metabolic activity of lactic acid bacteria and the associated microbial communities, including probiotics. During dairy fermentation, these microorganisms generate bioactive compounds, such as bioactive peptides, exopolysaccharides, organic acids and other metabolites, which may contribute to host health. There is emerging evidence that fermented dairy products can influence gastrointestinal function, immune regulation, metabolic health and cardiovascular risk, via mechanisms involving modulation of the gut microbiota, stabilisation of the epithelial barrier and inflammatory signalling pathways. In addition, fermentation may improve lactose digestion, enhance nutrient bioavailability, and generate peptides with anti-hypertensive or antioxidant properties. However, translating these results into consistent health benefits is challenging due to the significant variability in microbial strains, product composition, processing conditions and dosage. Safety considerations such as biogenic amines, sodium content, allergenicity and antimicrobial resistance also require careful monitoring. Future progress in this field will depend on improved product characterisation, strain-level identification and well-designed human intervention studies that integrate multi-omics approaches. In conclusion, fermented dairy products show great potential as a source of bioactive compounds, but more robust clinical evidence and standardised methodologies are required to firmly establish their role in promoting human health.\n\nID: 42185771\nTitle: Probiotic characterization of Lactobacillus helveticus BGTRM7-58 from Khiki cheese: safety, antimicrobial activity, antioxidant capacity, and anti-biofilm effects against Staphylococcus aureus.\nAbstract: Traditional Iranian cheeses, especially \"Khiki cheese,\" represent valuable sources of indigenous lactic acid bacteria with potential probiotic properties. This study evaluated the probiotic attributes, safety profile, antimicrobial efficacy, antioxidant capacity, and anti-biofilm activity of Lactobacillus helveticus BGTRM7-58, a strain isolated from Khiki cheese. The strain demonstrated considerable anti-adhesion capability against Staphylococcus aureus. The cell-free supernatant (CFS) exhibited potent antimicrobial activity, displaying a minimum inhibitory concentration (MIC) of 15.625 mg/mL against S. aureus. Furthermore, the CFS inhibited biofilm formation by 87% at 4× MIC and disrupted pre-established mature biofilms by 89% at the same concentration. In vitro cytotoxicity assessment revealed dose-dependent antiproliferative effects against cancer cell lines. Quantitative real-time PCR analysis indicated significant downregulation of key staphylococcal virulence genes, most notably a 47% reduction in agr expression. The strain also exhibited substantial antioxidant activity, scavenging 68.67%, 71.75% of DPPH and ABTS radicals, respectively. Comprehensive safety evaluation confirmed the absence of hemolytic and DNase activities, no production of biogenic amines, and susceptibility to clinically relevant antibiotics. Taken together, these findings indicate that L. helveticus BGTRM7-58 fulfills the fundamental criteria for a safe and functional probiotic strain, highlighting its potential for application in functional food formulations and strategies aimed at controlling biofilm-associated infections.\n\nID: 42134555\nTitle: Neural and metabolic mechanisms of emetogenic foodborne toxins via the brain-gut axis in ageing and cachexia.\nAbstract: Emetic foodborne toxins (bacterial enterotoxins, mycotoxins like DON/ZEA, marine toxins, cereulide, T-2 toxin, domoic acid, and biogenic amines such as histamine) cause acute gastrointestinal reactions and chronic systemic pathologies. This review outlines their activation of the brainstem's area postrema (AP) via intestinal barrier disruption, dysbiosis, vagus nerve stimulation, or direct central penetration. Acute exposure induces anorexia/defense responses through AP/NTS receptor pathways (GLP-1R, CCK, PYY, ghrelin, GDF15-GFRAL, 5-HT3). Chronic exposure impairs the AP-hypothalamus-locus coeruleus (LC) pathway, causing neuropsychiatric disorders, cachexia-like metabolic reprogramming, and multi-organ dysfunction. The gut microbiota play pivotal roles in toxin metabolism, bioactivation, and detoxification; microbial dysbiosis and LPS translocation amplify systemic inflammation. The elderly, immunocompromised individuals, and patients with comorbidities are particularly vulnerable due to weakened barriers, immunosenescence, and polypharmacy. This review elucidates the toxin-induced acute-to-chronic cascade via the gut-brain-neuro-metabolic network, discusses current limitations and future directions, and provides a theoretical basis for understanding chronic pathogenic mechanisms and complex comorbidities.\n\nID: 42123770\nTitle: Bioactive Compounds in Coffee: Metabolism, Bioavailability and Health Effects-A Review.\nAbstract: Coffee is a very popular psychoactive beverage with a complex composition. Besides its stimulant effect due to caffeine, it contains several bioactive compounds with antioxidant properties and potent metabolic activity. Its clinical efficacy is fundamentally determined by the bioavailability and metabolic fate of its constituents. The bioactive components of coffee, such as polyphenols, melanoidins, phytosterols, biogenic amines, and carotenoids, have notable antioxidant, anti-inflammatory, and immunomodulatory effects. This review aims to present the main bioactive components of coffee, their biological effects, mechanisms of action, and the influence of preparation methods and individual variability on metabolic outcomes in common chronic diseases. The data are synthesized from clinical, prospective, and interventional studies to examine how processing variables and biological metabolism influence the health-promoting potential of coffee antioxidants. Brewing methods like hot filtration optimize the extraction of these antioxidants. Individual clinical outcomes are further modulated by genetic polymorphisms and gut microbiota variability, which influence the activation of the cellular Nrf2 antioxidant defense pathway.\n\nID: 42115271\nTitle: Altered gut microbiota and metabolites in children with non-organic anorexia: a multi-omics integration study.\nAbstract: Gut microbiota alterations have been linked to childhood eating disorders, but the functional and metabolic changes in non-organic anorexia (NOA) remain poorly understood. This study aimed to characterize the gut microbial composition, function, and metabolic profiles in children with NOA using an integrated multi-omics approach. A case-control study was conducted involving 88 children aged 1-5 years (48 NOA, 40 healthy controls). Gut microbiota composition was assessed via 16S rRNA gene sequencing of all fecal samples. Subsequently, the five most representative samples from each group were selected for deep shotgun metagenomic sequencing and liquid chromatography-mass spectrometry (LC-MS) based non-targeted metabolomics. NOA children showed significantly higher microbial richness and diversity (Chao1, Shannon; P < 0.001). The NOA group had elevated Firmicutes, Bacteroidota, Bacteroides, Faecalibacterium, Subdoligranulum, and Roseburia, but reduced Actobacteriota, Bifidobacterium, and Enterococcus. Metagenomics revealed downregulated riboflavin metabolism and upregulated fat digestion/absorption pathways in NOA (P < 0.05). Metabolomics identified 26 differential fecal metabolites, including decreased L-carnitine derivatives and elevated tyramine glucuronide involved in bile secretion. These metabolites were significantly correlated with altered bacterial genera. Our integrated multi-omics analysis demonstrates that NOA in children is associated with a specific gut ecosystem characterized by altered microbiota structure, perturbed microbial metabolic functions (particularly riboflavin metabolism), and corresponding host-microbiota co-metabolic disturbances. These findings provide novel evidence for the disrupted \"microbiota-metabolite\" axis in NOA, offering new mechanistic insights.\n\nID: 42042907\nTitle: Effects of Probiotic Supplementation on Gut Microbiota and Fecal Metabolome in Autism Spectrum Disorders: A Secondary Analysis of a Randomized Clinical Trial in Preschoolers.\nAbstract: Recently, a randomized clinical trial evaluated whether a six-month probiotic administration could reduce symptom severity in preschool children with Autism Spectrum Disorders (ASD), with (GI) or without (NGI) gastrointestinal symptoms. Significant positive changes were observed only in NGI children. A second explorative study on children prior to intervention identified a fecal metabolome fingerprint associated with ASD severity. Building on these findings, the present study aimed to assess whether metabolomics could monitor changes in ASD severity following probiotic administration using a subset of samples from the same trial. Second, this study aimed to identify fecal metabolites to be monitored in children to predict whether their autism severity may decrease after probiotic or placebo treatment. Evaluations of the fecal metabolome and microbiota could be completed on 57 children before and after a double-blind administration of a probiotic mixture or a placebo. In NGI children the probiotic was found to influence the concentration of the amino acids aspartate, leucine, tryptophan, and valine, together with nicotinate and the short chain fatty acids acetate, butyrate, isobutyrate, and propionate. Lactobacilli and Sutterella showed significant changes in response to probiotic administration (p < 0.05). Acetate, 4-hydroxyphenyl, galactose, proline, and tyramine were identified as key fecal metabolites for prediction purposes. The present exploratory analysis, despite the small sample size, suggests that fecal metabolomics may provide a useful approach for monitoring and potentially for predicting changes in ASD severity following probiotics administration.\n\nID: 41840712\nTitle: Characterization of age-related changes in the gut microbiome and metabolome of Kunming dogs and their associations with police performance.\nAbstract: Gut microbiota plays a pivotal role in regulating the host's central nervous system (CNS) activity and behavior. However, its influence on the police performance of Kunming dogs and the underlying mechanisms remain largely unexplored. This study was the first to apply multi-omics technologies to investigate the dynamic variations in gut microbiota and their metabolic profiles across different ages of Kunming dogs. Furthermore, we systematically examined the associations between these microbial alterations and police performance metrics, providing a theoretical foundation for enhancing the working capabilities of Kunming dogs through targeted modulation of intestinal microecology. The study showed that puppies, young dogs and adult dogs had significantly better police performance than elderly dogs, with young dogs exhibiting the highest scores. Analysis of 16S rRNA sequencing demonstrated that gut microbial diversity and stability were highest during the young dog stage, gradually declining with age. Metagenomic analysis revealed that the abundance of Lactobacillus acidophilus, Lactobacillus johnsonii, Limosilactobacillus reuteri, Ligilactobacillus animalis and Muribaculum gordoncarteri were strongly correlated with police performance. The results of metagenome-assembled genomes (MAGs) indicated that the above species have functional genes involved in GABAergic and glutamatergic synapse pathways. Furthermore, metabolomic analysis showed that differential metabolites were enriched in the neuroactive ligand-receptor interaction pathway, in which GABA (γ-aminobutyric acid), histamine and tyramine metabolites were positively correlated with the above species and police performance. The species L. acidophilus, L. johnsonii, L. reuteri, L. animalis, and M. gordoncarteri, which were enriched in the gut of puppies and young Kunming dogs, may potentially influence the nervous system through the production of neurotransmitters and neuromodulators, suggesting a possible association with police performance. Video Abstract.\n\nID: 41819674\nTitle: In vitro and in vivo toxicological safety assessment of indigenous probiotic Lacticaseibacillus rhamnosus NCDC 610.\nAbstract: Lacticaseibacillus rhamnosus NCDC 610, isolated from the cereal-based fermented milk product Rabdi, has previously demonstrated antimicrobial, immunomodulatory, hypocholesterolemic, and antidiabetic properties. To ensure its safe application in foods and probiotic formulations, a comprehensive preclinical safety assessment was performed in accordance with ICMR and OECD guidelines. A battery of in vitro and in vivo assays was conducted to evaluate virulence factors, mucin degradation, biogenic amine production, antibiotic susceptibility, cytotoxicity in HT-29 cells, and adhesion ability. Additionally, acute and sub-acute oral toxicity studies were performed in C57BL/6 mice, including haematological, biochemical, histopathological, and immunological parameters. Lcb. rhamnosus NCDC 610 lacked virulence-associated attributes and did not exhibit haemolytic, gelatinase, coagulase, DNase, β-glucosidase, or β-glucuronidase activities. It neither utilized mucin nor produced biogenic amines, as confirmed by colourimetric and HPLC analyses. Further, Lcb. rhamnosus NCDC 610 was susceptible to clinically relevant antibiotics, maintained >95% cell viability in HT-29 cells, and showed moderate adhesion to intestinal epithelial cells. In vivo studies revealed no treatment-related toxicity, behavioural abnormalities, organ damage, bacterial translocation, or adverse immune responses. Collectively, these findings demonstrate the in vitro and in vivo safety of Lcb. rhamnosus NCDC 610 and support its potential for further evaluation as a functional probiotic candidate.\n\nID: 41795531\nTitle: Enhancing safety and flavor of traditional Yucha: Autochthonous starters from Hainan fermented foods reduce biogenic amines and promote taste-active metabolites.\nAbstract: Yucha, a traditional fermented rice-fish product, faces challenges in inconsistent quality and safety. In this study, 69 lactic acid bacteria (LAB) were isolated from Yucha and shrimp paste in Hainan, China. Four strains, Lactiplantibacillus plantarum Lpl-YC37, Lacticaseibacillus paracasei Lpa-XJ120, and Pediococcus pentosaceus Ppe-YC39 and Ppe-XJ37 were selected as starters based on probiotic property and safety evaluation. Inoculation with these LAB starters significantly enriched beneficial metabolites, with Ppe-XJ37 showing a four-fold increase in acetic acid, the dominant short-chain fatty acids. Additionally, all LAB inoculation enhanced free amino acids, particularly L-glycine, improving flavor and nutritional value. Crucially, LAB inoculation drastically suppressed biogenic amines, reducing putrescine from 55.23 μg g-1 in the control to 5.77 μg g-1 in the Lpl-YC37 group, highlighting improved safety. These findings demonstrate that tropical fermented foods harbor indigenous LAB starters, providing a scalable approach to modernize these foods for improved quality and safety.\n\nID: 41630915\nTitle: Commensal human gut microbes produce species specific neuroactive compounds.\nAbstract: The gut microbiota communicates with multiple organs through neuroactive molecules, but the specific compounds produced remain unclear. We investigated eight commensal gut species, Lactococcus lactis, Enterococcus faecalis, Blautia producta, Clostridium symbiosum, Streptococcus thermophilus, Prevotella copri, Bacteroides fragilis, and Escherichia coli Nissle, using targeted and non-targeted LC-MS/MS. These bacteria differentially consumed glutamine, glutamate, and tryptophan, producing distinct neuroactive metabolites. For example, E. coli and B. producta generated high levels of gamma-aminobutyric acid (GABA), while P. copri was the sole producer of tryptamine. In the tyrosine pathway, E. faecalis synthesized tyramine and dopamine, and L. lactis, B. producta, and E. coli produced L-DOPA. Interestingly, none produced serotonin or its intermediates despite consuming tryptophan. Multiple species also generated short-chain fatty acids (SCFAs). These findings demonstrate that commensal microbes contribute to host neurochemistry by producing diverse neuroactive metabolites and SCFAs, highlighting the therapeutic potential of modulating the gut microbiota to influence human health.\n\nID: 41615647\nTitle: Correlation analysis of gut microbiota and metabolites in gastric cancer patients in plateau areas based on multi-omics technologies.\nAbstract: To characterize gut microbiota alterations and metabolic changes in gastric cancer (GC) patients from high-altitude regions using 16S rDNA sequencing and untargeted metabolomics. Fecal samples from 30 GC patients and 30 healthy controls in Qinghai Province were analyzed. Microbial diversity and composition were assessed via 16S rDNA sequencing, and metabolite profiles were determined using untargeted metabolomics. Correlations between significantly altered microbial taxa and metabolites were evaluated. Microbial diversity differed significantly between groups (P < 0.001). Proteobacteria abundance was higher in GC patients (P < 0.05). At the genus level, Prevotella_9, Streptococcus, and Lactobacillus showed significant differences (P < 0.05-P < 0.001). GC patients exhibited upregulation of desulfo-biotin, glycylproline, glycine, hydroxyhexanoic acid, tyramine, methanethiol oxidase, 5-aminopentanoic acid, citrulline, betaine, and formyl glutamic acid, and downregulation of cytidine, 5'-methylthioadenosine, trehalose, melezitose, lotaustralin, adenosine, creatinine, 5-methyluridine, raffinose, and galactitol. Proteobacteria correlated positively with desulfo-biotin, glycylproline, and glycine, while Lactobacillus correlated with several upregulated metabolites including tyramine and betaine (all P < 0.05). Cytidine correlated negatively with Proteobacteria, whereas creatinine and 5-methyluridine correlated positively with Prevotella_9. GC patients in high-altitude regions display distinct gut microbiota and metabolite profiles, with notable microbe-metabolite associations. These findings suggest potential biomarkers and therapeutic targets for GC in plateau populations.\n\nID: 41595985\nTitle: Gut Microbiota and Dopamine: Producers, Consumers, Enzymatic Mechanisms, and In Vivo Insights.\nAbstract: The human gut microbiota plays a key role in neurochemical communication, especially through the gut-brain axis. There is growing evidence that the gut microbiota influences dopamine metabolism through both production and consumption mechanisms. Two key bacterial enzymes are central to this process: tyrosine decarboxylase (TDC), which primarily catalyzes the decarboxylation of tyrosine to tyramine but can also act on L-DOPA to produce dopamine in certain bacterial strains, and aromatic L-amino acid decarboxylase (AADC), which can convert precursors such as L-DOPA, tryptophan, or 5-hydroxytryptophan into bioactive amines including dopamine, tryptamine, and serotonin. Identifying the bacterial families corresponding to TDC and AADC enzymes opens new avenues for clinical intervention, particularly in neuropsychiatric and neurodegenerative disorders, such as Parkinson's disease. Moreover, elucidating strain-specific microbial contribution and host-microbe interactions may enable personalized therapeutic strategies, such as selective microbial enzyme inhibitors or tailored probiotics, to optimize dopamine metabolism. Emerging technologies, including biosensors and organ-on-chip platforms, offer new tools to monitor and manipulate microbial dopamine activity. This article explores the bacterial taxa capable of producing or consuming dopamine, focusing on the enzymatic mechanisms involved and the methodologies available for studying these processes in vivo.\n\nID: 41550498\nTitle: The TAAR1 antagonist EPPTB ameliorates colitis via serotonin inhibition.\nAbstract: Inflammatory bowel disease (IBD) is characterized by gut dysbiosis and impaired microbial metabolite signaling. Emerging evidence suggests that gut microbial metabolites, such as trace amines (tryptamine, phenethylamine, and tyramine), function as endogenous TAAR1 agonists and may contribute to IBD pathogenesis. Our study identified elevated fecal trace amine levels in ulcerative colitis (UC) patients and DSS-induced colitis mice. In vitro, exposure to these trace amines enhanced 5-HT secretion in QGP-1 cells and ex vivo mouse colonic tissues, and this effect could be blocked by the TAAR1 antagonist EPPTB. In vivo, EPPTB treatment significantly mitigated DSS-induced colitis, as demonstrated by reduced weight loss, improved disease activity index (DAI), preserved colon length, and attenuated histopathological damage. Moreover, TAAR1 blockade reduced pro-inflammatory cytokines (TNF-α, IL-6, IL-1β) and increased IκB-α expression, restored intestinal barrier integrity (upregulating occludin and ZO-1, while downregulating cclaudin-2), and lowered colonic 5-HT levels by suppressing TPH1 expression. These findings suggest that TAAR1 inhibition alleviates colitis by modulating 5-HT signaling, positioning it as a promising therapeutic target for IBD.\n\nID: 41494586\nTitle: Microorganisms and Physicochemical Factors Controlling Biogenic Amines During Cheese Ripening: A Systematic Review.\nAbstract: Biogenic amines are nitrogenous compounds formed by amino acid decarboxylation, and their excessive accumulation in cheese may cause adverse health effects. This systematic review aimed to evaluate the effectiveness of probiotic strains and physicochemical factors in reducing biogenic amine levels during cheese ripening. Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, a comprehensive literature search was conducted in PubMed, Scopus, Web of Science, ScienceDirect, and Google Scholar for studies published between 2010 and 2024. Fourteen studies met the inclusion criteria. Among the identified biogenic amines, tyramine and histamine were most frequently reported at high concentrations. The combination of Lactobacillus acidophilus and Lactiplantibacillus plantarum demonstrated the highest efficacy, achieving up to 80% reduction in total biogenic amine levels. Optimal physicochemical conditions, including maintaining a pH range of 5.0-5.4, a ripening temperature around 15 °C, and a maturation period of 3-4 months, enhanced the efficiency of probiotic interventions. Environmental factors such as salt, moisture, fat content, and packaging methods significantly influenced biogenic amine accumulation. Integrating selected probiotics with controlled ripening parameters can minimize biogenic amine levels and improve cheese safety and quality. However, due to heterogeneity in probiotic strains, cheese types, and analytical techniques among the included studies, further standardized and large-scale investigations are required to better understand the mechanisms and optimize strategies for biogenic amine reduction in cheese production.\n\nID: 41364165\nTitle: Role of brain-gut axis in mechanism of gastrointestinal defense.\nAbstract: The digestive system, comprising gastrointestinal (GI)-tract and connecting organs, such as liver or pancreas, has a wide autonomy in the human body due to the presence of specific nervous and endocrine systems of its own and can act voluntarily without stimulation from the rest of the body. This wide physiological autonomy of a digestive tract does not exclude connection with other organs and central as well as peripheral mechanisms controlling nervous and hormonal systems. The vagal nerve is a structure connecting GI-tract with brain centers. Both, the afferent and efferent components of the vagal nerve innervate the GI-tract and modify its functions. An example of stimulants affecting afferent fibers of vagal nerve are digestive hormones, such as cholecystokinin (CCK), because CCK is commonly recognized as the gut hormone that stimulates specific receptors located at the endings of vagal afferent fibers and promotes the vago-vagal reflex. Recent studies have documented that GI-tract is a source of abundant hormones regulating the hunger - satiety centers in the hypothalamus via afferent fibers of the vagal nerve, forming the brain-gut axis. In addition, local endocrine cells in the GI-tract can produce biogenic amines, such as serotonin or histamine which also can stimulate afferent component of this axis. The complexity of brain - gut axis is augmented by the participation of other factors, that can influence it, such as metabolites of gut microbiota, changes in the intestinal permeability, the proinflammatory cytokines and other immune responses, activity of the stress hormones, such as adrenaline, cortisol and aldosterone. In addition, the presence of the short chain fatty acids (SCFA) can modify the bidirectional brain-gut and gut-brain axes activity, indirectly, as nutrients for specific bacterial species, or directly, by stimulation of the specific receptors located within the GI wall. In this review, we focused on the brain-gut axis is involved in the strenghtening of the mucosal barrier via maintaining of oxidative balance. The main process reaction causing cellular destruction is lipid peroxidation. Lipid peroxides disrupt the structure of cellular lipids, making this barrier more permeable. Increased cellular permeability of GI-tract barrier contributes to the stimulation of the brain-gut axis. Pharmacological agents, affecting mucosal blood flow, such as cyclooxygenase (COX) products, COX inhibitors and pentoxifylline, are also able to modify functions of the brain-gut axis. We conclude that brain-gut axis plays a particularly important role in maintaining of mucosal barrier in GI-tract and alteration in its functions is implicated in pathogenesis of various diseases of the gut.\n\nID: 41293416\nTitle: Safety evaluation of Lacticaseibacillus rhamnosus KF7 based on complete genome, phenotypic assays and alternative models: Caenorhabditis elegans.\nAbstract: This study evaluated the safety of Lacticaseibacillus rhamnosus (L. rhamnosus) KF7, a probiotic strain originating from kefir, for potential use in infant and children's food products in China. The safety evaluation was conducted through a comprehensive approach involving whole-genome sequencing, in vitro and in vivo studies using alternative models: Caenorhabditis elegans (nematodes). Genomic analysis confirmed the absence of virulence factors and antibiotic resistance genes in KF7. Phenotypic characterization demonstrated that KF7 exhibits no antibiotic resistance, does not produce indole, is non-hemolytic, and lacks amino acid decarboxylase activity. Furthermore, KF7 was found to not produce histamine and generate only a minimal amount of tyramine when cultured in MRS medium supplemented with amino acids. The strain was also shown to produce both L- and D-lactic acid, with the concentration of D-lactic acid falling within a safe range. To further evaluate the safety of KF7 in vivo, nematode model was employed, with Pseudomonas aeruginosa serving as a pathogenic control and L. rhamnosus GG, known to be safe for infants and children, as a positive control. The results demonstrated that KF7 does not adversely affect nematode egg-laying, egg development, growth, locomotion, or lifespan. Instead, it appeared to have beneficial effects on gut microbiota and extending the nematodes' lifespan. In summary, this study established the method of using nematode as an in vivo evaluation to the safety of probiotics, and the safety data of the KF7 strain was supplemented by in vitro research, which proved that KF7 has a certain degree of safety.\n\nID: 41286532\nTitle: Low-temperature two-stage probiotic fermentation enhances nutrition and safety of pig liquid feed.\nAbstract: Antinutritional factors present in complete feeds markedly diminish digestive and absorptive efficiency in animals, thereby affecting growth performance and resulting in economic losses. Liquid fermentation technology has been demonstrated to be an effective method of reducing antinutritional factors and enhancing the nutritional value of complete feeds. However, there is a lack of systematic research on the liquid fermentation and the screening of bacterial strains for use. In the present study, Bacillus subtilis and Lactobacillus plantarum characterized by excellent low-temperature tolerance, great enzyme activity, strong bacteriostatic capacity, and exceptional acid production, were evaluated for their suitability in a two-stage (aerobic followed by anaerobic) liquid fermentation process of complete pig feed. The results demonstrated that soybean antigenic protein and crude fiber underwent significant degradation, while crude protein and acid-soluble protein content exhibited significant increases in the feed following two-stage fermentation. Additionally, the accumulation of biogenic amines was inhibited to ensure the palatability of the feed. Furthermore, two-stage fermentation significantly enhanced the antioxidant and enzymatic activity of the feed. High-throughput 16S rRNA sequencing revealed an increased relative abundance of beneficial bacteria and a decreased abundance of pathogenic bacteria after fermentation. This study corroborated that a two-stage fermentation process could enhance the nutritional value, safety, and probiotic functionality of animal feeds. This finding provides a theoretical foundation for the development of functional fermented feeds and provides the necessary technical support for the practical application of liquid fermentation feeds. KEY POINTS: • Developed a novel low-temperature two-stage liquid fermentation feed strategy using Bacillus subtilis 3-16 and Lactobacillus plantarum E5 • Significantly degraded antinutritional factors and biogenic amines, while increasing the crude protein, acid-soluble protein, enzymatic activity, and antioxidant capacity of complete pig feed • Promoted beneficial microbiota dominance (e.g., Lactobacillus plantarum and Bacillus subtilis, while reducing pathogenic bacteria (e.g., Escherichia coli and Staphylococcus aureus).\n\nID: 41254537\nTitle: Biotechnological potential and genomic analysis of the Leuconostoc mesenteroides F17 and F18 strains isolated from camel milk.\nAbstract: Camel milk is known for its distinctive nutritional and antimicrobial properties. Thus, it offers a valuable niche for discovering novel probiotic strains with potential health benefits. In this context, two Leuconostoc mesenteroides strains, F17 and F18 were isolated from this dairy matrix and their properties analysed. Also, to gain deeper insight into their probiotic and technological traits, the sequencing of the whole genomes of both strains was conducted, revealing key genetic features supporting their suitability as starter cultures. The two bacteria displayed desirable technological properties including among them rapid milk acidification capability as well as proteolytic and lipolytic activities. F17 and F18 produced riboflavin (0.11 and 0.15 mg/L) and exopolysaccharides (1.8 g/L and 3.7 g/L) characterized as dextran by physicochemical analysis. The F17 and F18 DsrD dextransucrases of ~ 170 kDa, responsible for the dextran synthesis, were visualized by a zymogram analysis and their dsrD coding genes, with 98.99% identity, were identified in their genomes. After 24 h growth in a sucrose-containing medium, analysis of metabolic fluxes in culture supernatants of both bacteria demonstrated accumulation of the sweetener mannitol and the antimicrobial lactic acid; at the levels of 59 mM and 76.57 mM in the case of the best performer (F18). Furthermore, the results demonstrated that both strains exhibited good survival rates under in vitro simulated stomach duodenum-passage. A high surface adhesion was also observed for F17 and F18 including hydrophobicity of 30.15% and 31.72% and auto-aggregation ability of 44.71% and 53.23%, with a good resistance to phenol exposure and to moderated heat shock. As expected from the genomes inspection, the safety analysis revealed that the two strains were susceptible to most of the tested antibiotics, and none of them showed any hemolytic activity or biogenic amines synthesis capability. Both cultures supernatants exhibited significant growth inhibition of foodborne pathogens, presumably due to the present of lactic acid. Thus, these findings suggest that camel milk may harbor lactic acid bacteria with promising technological and probiotic traits, as exemplified by F17 and F18.\n\nID: 41191059\nTitle: Whole genome sequencing to assess the safety and probiotic potential of Pediococcus pentosaceus L1 isolated from pickled radish.\nAbstract: This research aimed for the safety and probiotic potential assessment of Pediococcus pentosaceus L1, isolated from pickled radish, through its whole genome sequencing analysis and in vitro evaluation. The genome size of Ped. pentosaceus L1 was 1,751,467 bp long with an average guanine-cytosine (GC) ratio of 37.41% and contained 1739 genes in the coding region. The functional annotation of the L1 strain demonstrated that it exhibited excellent probiotic potential and health-promoting properties, with numerous genes linked to the carbohydrate metabolism system, stress resistance, and environmental adaptation. The analysis of virulence factor and antimicrobial resistance indicated the absence of any virulence-related or antibiotic resistance genes in Ped. pentosaceus L1, adding value to its safety profile. In vitro experiments showed that Ped. pentosaceus L1 presented high cell surface hydrophobicity, strong antioxidant activity, no hemolytic activity, and did not synthesize biogenic amines including cadaverine, putrescine, or agmatine. Additionally, its auto- and co-aggregation survival rates indicated its probiotic potential. Ped. pentosaceus L1 also exhibited exceptional exopolysaccharide (EPS) production potential, achieving an enhanced EPS yield in a glucose-supplemented medium. Together, all these characteristics make Ped. pentosaceus L1 an optimistically safe choice for use as a potential probiotic.\n\nID: 41154100\nTitle: Doenjang (Traditional Korean Fermented Soy Paste) Attenuates Development of Colitis-Associated Colorectal Cancer by Modulating Apoptotic, Inflammatory, and Gut Microbiota Pathways.\nAbstract: Colitis-associated colorectal cancer (CAC) is a type of colorectal cancer (CRC) that develops as a result of chronic inflammation, particularly in patients with inflammatory bowel diseases such as ulcerative colitis and Crohn's disease. Persistent intestinal inflammation and dysbiosis of gut microbiota under these conditions are major contributors to CRC progression. Doenjang, a traditional Korean fermented soybean paste, contains probiotics that influence intestinal microbiota composition, as well as biogenic amines (BAs), harmful compounds generated during fermentation. We analyzed the bacterial composition and BA content of Doenjang and evaluated its effects on CAC in a mouse model of AOM/DSS-induced CAC. Results revealed that Doenjang contains diverse beneficial probiotics alongside BAs. Doenjang significantly reduced tumor formation and attenuated CAC progression by modulating inflammatory and apoptotic pathways and suppressed the expression of pro-inflammatory cytokines (TNF-α, IL-1β, and IL-6) by inhibiting the NF-κB pathway. Additionally, Doenjang restored intestinal epithelial barrier integrity by increasing the expression of mucin-related genes (MUC-2, MUC-3) and protective factors like TFF-3. Gut microbiota analysis revealed that Doenjang promoted a healthier gut environment by increasing microbial diversity and reducing inflammation-related bacterial populations. These findings suggest that Doenjang helps prevent and manage CAC by modulating inflammatory responses and gut microbiota composition.\n\nID: 42437266\nTitle: Global and regional inequalities in dairy recommendations: a natural language processing analysis of food-based dietary guidelines across income groups.\nAbstract: Food-based dietary guidelines (FBDGs) are key public health instruments aimed at promoting healthy dietary patterns. However, dairy-products recommendations vary substantially across countries, reflecting not only scientific evidence but also socioeconomic conditions, institutional capacity, and food system characteristics. The extent to which these differences are structured linguistically across income levels has not been systematically quantified. The present study aims to explore the use of advanced NLP techniques to characterize semantic differences and similarities in dairy-products dietary messages within FBDGs from countries with different levels of socioeconomic development. We conducted a comparative analysis of dairy-products recommendations extracted from national FBDGs officially recognised by the Food and Agriculture Organization, covering 98 countries. Using advanced natural language processing techniques, including lexical frequency analysis, co-occurrence networks, and latent topic modelling, we examined semantic patterns in recommendation statements and justificatory texts. Countries were stratified according to World Bank income group classifications. Across all income groups, \"milk\" emerged as the central lexical anchor of dairy recommendations. However, high-income countries demonstrated greater lexical diversity and semantic complexity, incorporating differentiated references to product types, fat content, and fermentation (e.g., yogurt, cheese, low-fat). In contrast, low- and lower-middle-income countries presented more general and nutritionally basic messaging, primarily focused on consumption adequacy and child nutrition. Justification texts consistently contained higher nutrient-related terminology density than recommendation statements. Dairy-products dietary messaging in national FBDGs shows consistent descriptive differences across income groups. These semantic disparities likely reflect contextual differences in institutional capacity, epidemiological priorities, and food system infrastructure. The findings may be particularly relevant for the Americas, where high-, upper-middle-, and lower-middle-income countries coexist within a region undergoing rapid nutrition transitions and facing the persistent triple burden of malnutrition. In this context, PAHO/WHO may play an important role in supporting greater harmonisation of dietary guidance across diverse socioeconomic settings. NLP-based approaches offer scalable tools for monitoring global nutrition policy discourse and supporting evidence-informed policy development.

Nutrient profiling systems (NPSs) aim to guide healthier food choices through labeling and consumer-facing technologies but vary in accessibility and how well they distinguish food healthfulness. The primary objective was to compare a web-enabled, ratio-based NPS, Nutrient Consume Score (NCS), and its underlying nutrient ratios with 4 other leading NPSs, Nutri-Score, Health Star Rating, NOVA Classification, and Food Compass 2.0, by examining associations with obesity and blood pressure. Secondary objectives included assessing associations with cardiometabolic biomarkers and identifying food categories contributing most to each score. Cross-sectional study of NHANES 2015-2016 data from 9971 adults aged ≥20 y were analyzed. Dietary intake was assessed using a single 24-h dietary recall (day 1), and NPS scores were calculated. Multivariable regression models adjusted for sociodemographic and health factors examined associations with obesity, blood pressure, and cardiometabolic biomarkers. Compositional analysis evaluated food categories driving scores. Higher NCS was associated with lower BMI [β = -0.64 kg/m2 per 10-unit increase; 95% confidence interval (CI): -0.86, -0.41; P < 0.0001], waist circumference (β = -1.63 cm; 95% CI: -2.23, -1.02; P < 0.0001), systolic blood pressure (β = -1.01 mm Hg; 95% CI: -1.67, -0.35; P < 0.0051), and diastolic blood pressure (β = -0.56 mm Hg; 95% CI: -0.90, -0.23; P < 0.0026), with effect sizes comparable with other NPSs. Calorie-to-weight, sodium-to-potassium, and saturated-to-unsaturated fat ratios were associated with weight outcomes, whereas sodium-to-potassium and carbohydrate-to-fiber ratios were associated with blood pressure outcomes. The NCS was associated with weight and blood pressure in this cross-sectional analysis, with effect estimates comparable in magnitude with other commonly used NPSs. These findings support the potential utility of a ratio-based, web-enabled NPS for assessing diet quality in relation to cardiometabolic risk factors.\n\nID: 42436036\nTitle: B Vitamins bioavailability in plant-based foods: Beyond content to nutritional impact.\nAbstract: B vitamins are essential water-soluble cofactors involved in metabolic regulation and neurological function. In plant-based diets, maintaining adequate B vitamin status is challenging because nutritional value depends not only on vitamin content but also on bioavailability. Although many plant foods contain substantial quantities of B vitamins, their absorption is generally lower than that from animal-derived sources due to differences in chemical form, matrix associations, and conjugation state. Thiamine and niacin often require liberation from bound forms; folates must undergo enzymatic deconjugation; vitamin B6 frequently occurs in glycosylated forms with reduced biological activity; and vitamin B12 is absent from unfortified plant foods. Bioavailability is further modulated by dietary composition, gastrointestinal conditions, and host genetic variability. Assessment approaches, such as in vitro models, cellular transport systems, and in vivo biomarkers, provide complementary but incomplete perspectives on physiological availability. Fermentation has emerged as a promising strategy to enhance B vitamin bioavailability in plant foods through microbial synthesis, matrix modification, and reduction of antinutritional factors. Applications in cereals, legumes, vegetables, and fruits demonstrate substantial improvements in vitamin content and accessibility. This chapter emphasizes the disconnect between analytical vitamin content and physiological impact and positions fermentation as a scalable approach to optimize B-vitamin nutrition in plant-based dietary patterns.\n\nID: 42435896\nTitle: Reply - Letter to the editor- Re \"Pulse-based dietary patterns in older adults: interpreting PRODMED1 through matrix quality, iron kinetics, and functional outcomes\" (Zhao Z, Shen T).\nAbstract: \n\nID: 42435895\nTitle: The association of dietary inflammation index (DII) and health-related outcomes: an umbrella review of systematic reviews.\nAbstract: Accumulating evidence suggests that adherence to pro-inflammatory dietary patterns, as reflected by elevated Dietary Inflammatory Index (DII) scores, is associated with adverse health outcomes. This umbrella review investigated the association between the DII and health-related outcomes. A comprehensive search was performed through PubMed, Scopus, Web of Science Core Collection and epistemonikos.org databases to identify related systematic reviews and/or meta-analyses published until July 2024. The identification of relevant studies, data extraction and critical appraisal of the included studies were performed independently by two investigators. The methodological quality was appraised using the Assessment of Multiple Systematic Reviews 2 (AMSTAR2) tool. The findings are presented using a narrative analysis. A total of 90 systematic reviews and/or meta-analyses were identified, evaluating associations between DII and various health outcomes: cancer (n = 32), mortality (n = 12), metabolic disorders (n = 8), cardiovascular diseases (CVDs) (n = 5), neurocognitive and mental health outcomes (n = 18), alterations in body composition (n = 6), bone disorders (n = 4), neurological disorders (n = 1), and pregnancy and maternal health outcomes (n = 3). Our findings suggest that high scores of DII have an adverse effect on various health outcomes compared to lower scores. However, the overall certainty of evidence is limited, as most included reviews were rated as having low or critically low methodological quality. The findings suggest that diets with high inflammatory load may represent a significant health risk factor, reinforcing the need for preventive interventions that promote anti-inflammatory dietary patterns. Future randomized controlled trials are warranted to confirm the potential benefits of anti-inflammatory diet patterns on health-related outcomes.

CYP450 enzymes represent a key interface between metabolic stress, xenobiotic handling, oxidative injury, and nutrition-related exposures, yet their role in MASLD/MASH has not been fully integrated from a nutrition-informed perspective. This review maps nutrition-exposure-CYP relationships across MASLD/MASH by integrating dietary patterns, food-processing exposures, contaminants/additives, and bioactive compounds within a structured qualitative framework. The reviewed evidence suggests that obesity, high-fat diet exposure, fructose co-exposure, and fatty acid composition may reshape hepatic CYP responses through isoform-, exposure-, and endpoint-dependent mechanisms. Human liver tissue and microsome studies provide relatively stronger translational evidence for altered CYP3A4 expression, activity, and clearance in NAFLD/NASH, whereas evidence for many nutrition-related exposures remains primarily animal-based, in vitro, or mechanistic. Macronutrient-related pathways, including fructose with high-fat intake and omega-6/omega-3 oxylipin imbalance, appear to influence CYP-mediated lipid and inflammatory signaling. Food-derived contaminants such as nitrosamines, aflatoxin B1, and acrylamide provide biologically plausible examples of CYP-dependent bioactivation in metabolically vulnerable liver contexts, although direct human MASLD/MASH validation remains limited. Evidence for food additives and phytochemicals is more preliminary and should be interpreted mainly as hypothesis-generating rather than clinically established. Across the reviewed evidence, metabolic inflammation appears to favor pro-oxidant CYP pathways, including CYP2E1 and CYP4A/4F, while suppressing or altering detoxification and epoxygenase-related pathways, including CYP3A and CYP2C/2J. However, changes in CYP expression do not necessarily translate into altered enzymatic activity or clinical clearance. We conclude that nutrition-related CYP remodeling may represent a mechanistic and translational interface linking diet, oxidative injury, xenobiotic handling, and MASLD/MASH progression. Future studies should integrate dietary exposure assessment with CYP activity or clearance phenotypes, oxidative stress biomarkers, gut-liver axis markers, and MASLD/MASH stage-specific clinical outcomes.\n\nID: 42435090\nTitle: Association between the traditional Chinese diet, non-communicable diseases and all-cause mortality: a longitudinal study based on China Health and Nutrition Survey (CHNS).\nAbstract: Traditional diets may reduce non-communicable disease (NCDs) risk. No research has examined associations between the traditional Chinese diet (TCD), defined using an a priori method, and NCD-related outcomes or all-cause mortality. This study aimed to assess the relationship between TCD adherence, NCD-related outcomes, and all-cause mortality. This longitudinal study utilised data from the China Health and Nutrition Survey (CHNS) between 1997 and 2011. Eligible participants were aged 18-74, had no NCDs at baseline, and participated in at least two survey waves. TCD adherence was assessed using a recently developed TCD index. Higher index scores indicate greater adherence; participants were categorised into low (0-6), medium (7-11), and high (12-23) adherence. Mixed-effects multilevel logistic regression and Cox proportional hazards models assessed associations with CVD, diabetes, cancer, obesity/central obesity, hypertension, and all-cause mortality. Among 11,158 participants (mean age 42.2 years, 51.3% women), high TCD adherence was associated with lower risk of CVD (OR: 0.73, 95% CI 0.61, 0.87) and all-cause mortality (HR: 0.73, 95% CI 0.63, 0.87), but higher risk of obesity (OR: 1.19, 95% CI 1.08, 1.32) and central obesity (OR: 1.19, 95% CI 1.12, 1.26). However, when standardising the energy intake on a common basis, TCD adherence was inversely associated with obesity and central obesity. Higher adherence to the TCD was associated with reduced risk of CVD and all-cause mortality in this sample of Chinese adults. The positive association with obesity highlights the need to consider total energy intake in future dietary recommendations.\n\nID: 42435080\nTitle: Omnivorous and plant-based dietary patterns: a comparative analysis using data-driven and index-based approaches.\nAbstract: Plant-based diet (PBD) followers are growing worldwide. The aim was to explore the dietary profile of PBDs, taking the omnivorous (OMN) diet as a reference. A cross-sectional study was carried out. A total of 760 participants were included, of whom 161 self-identified as vegan, ovo-lacto-vegetarian, or pesco-vegetarian. Intakes of 175 foods, assessed through a food frequency questionnaire (FFQ), were adjusted for energy intake. The intake of 32 food groups was compared across diet types using Kruskal-Wallis and post-hoc tests. Adherence to established a priori dietary patterns (Pro-vegetarian, Mediterranean, and EAT-Lancet) diet was assessed. A posteriori dietary patterns were characterized using principal component analysis (PCA), k-means and hierarchical clustering, amongst others. Per 1000 kcal, daily mean intakes of legumes (> 48.2 g), vegetables/mushrooms (> 209.9 g), nuts (> 10.2 g), and whole grains (> 24.7 g) were higher in the PBD groups than OMN (p < 0.001). The three a priori dietary indices were inter-correlated (rho = 0.4-0.6) and OMN scored lower than the PBD groups (p < 0.001). PCA revealed a PBD-like pattern (variance: 15.0%), an unhealthy (7.2%), and a mixed animal-PBD pattern (5.5%). The clustering methods identified similar groupings of the PBD participants, and a group of PBD-like OMN (N = 61). The latter, compared with the other OMN patterns, showed significantly lower intakes of milk (48.0 vs. > 95.2 ml), red meat (13.9 vs. > 17.8 g), processed meat (9.0 vs. > 14.0 g), and precooked foods (9.0 vs. > 12.2 g), alongside higher intakes of whole grains (25.5 vs. < 20.8 g), nuts (13.8 vs. < 8.3 g), and vegetables (207.7 vs. < 161.3 g). Thus, food choices between OMN, vegetarians and vegans differ, beyond the exclusion of animal foods. PBDs present common characteristics despite their diversity, and some OMN share these dietary features.\n\nID: 42435067\nTitle: Correction: Trimester-specific associations of maternal prenatal dietary patterns with fetal growth: a prospective pre-birth cohort study.\nAbstract: \n\nID: 42434742\nTitle: Integrative oncology in colorectal cancer: evidence-based strategies from prevention through survivorship.\nAbstract: Colorectal cancer (CRC) is a leading global malignancy, with approximately 1.9 million new cases and over 900,000 deaths recorded in 2022, yet evidence-based integrative oncology strategies remain inconsistently incorporated into routine care. This narrative review synthesizes current evidence across the full CRC care continuum, from primary prevention through long-term survivorship. High-fiber diets, Mediterranean dietary patterns, calcium supplementation, regular physical activity, healthy weight maintenance, and berberine each demonstrate reproducible CRC risk reduction in large prospective cohorts and multicenter randomized controlled trials. The CHALLENGE trial (NEJM 2025) provides the first randomized phase 3 evidence that structured exercise after adjuvant chemotherapy reduces disease recurrence (HR 0.72) and death (HR 0.63) in colon cancer. Aspirin chemoprevention requires individualized risk-benefit assessment per 2022 US Preventive Services Task Force guidelines; preliminary CaPP3 trial data (conference presentation, June 2025; not yet peer-reviewed) suggest non-inferiority of low-dose aspirin (75-100 mg/day) to 600 mg/day in Lynch syndrome, pending formal publication. Fusobacterium nucleatum promotes colorectal carcinogenesis through five mechanistically distinct pathways: FadA-mediated Wnt/β-catenin activation, Fap2- and CbpF-mediated immune evasion via TIGIT and CEACAM1, succinate-HIF-1α-EZH2-mediated immune suppression, Hippo pathway-mediated suppression of pyroptosis, and autophagy-induced chemoresistance. Perioperative multi-strain probiotics significantly reduce postoperative infectious complications, and fecal microbiota transplantation shows preliminary promise for sensitizing microsatellite-stable CRC to immunotherapy. The 2022-2024 SIO-ASCO and ASCO-SIO clinical practice guidelines endorse mindfulness-based interventions, yoga, and acupuncture for anxiety, depression, fatigue, and cancer-related pain. Systematic integration of these interventions into multidisciplinary CRC care requires standardized implementation frameworks, CRC-specific clinical trials for mind-body modalities, and bioavailability-optimized phytochemical formulations.\n\nID: 42434315\nTitle: The Feasibility, Acceptability and Impact of a Remotely Delivered Whole-Food Plant-Based Education Program.\nAbstract: Chronic conditions linked to Western dietary patterns, together with the environmental impacts of high animal product consumption, highlight the need for scalable lifestyle medicine education strategies that support shifts toward plant-based eating. This pilot study examined the feasibility and acceptability of a 5-week, remotely delivered, nutrition-focused lifestyle medicine education program centered on whole-food plant-based eating, and examined changes in dietary intake, knowledge, skills, and perceptions. The pilot program comprised five weekly 90-minute interactive Zoom sessions covering whole-food plant-based principles, health and environmental considerations, and practical strategies for dietary change. Participants completed 24-hour dietary recalls using ASA24-AU and surveys assessing knowledge, skills, and perceptions at baseline and post-intervention. Nine women aged 20 to 61 years completed the pilot program. Acceptability was high (mean rating 4.07/5). Participants reported improvements in whole-food plant-based knowledge, greater confidence in food preparation, and more favorable perceptions of taste, satiety, and convenience. Significant reductions were observed in energy intake, cholesterol, sodium, selenium, vitamin B12, and percent energy from protein. A short-duration online whole-food plant-based education program was feasible, well accepted, and associated with measurable improvements in dietary behaviors and perceptions. Larger studies incorporating clinical outcomes and longer follow-up are warranted to assess long-term effectiveness and sustainability.\n\nID: 42433782\nTitle: Dietary fatty acid intake and the risk of pancreatic cancer: a dose-response meta-analysis of observational studies.\nAbstract: The impact of fatty acids on pancreatic cancer (PC) risk remains contentious, prompting evaluation through current observational evidence. This systematic review and dose-response meta-analysis of observational studies aim to examine the association between dietary polyunsaturated fatty acids (PUFAs), monounsaturated fatty acids (MUFAs), saturated fatty acids (SFAs), trans fatty acids (TFAs), and the risk of PC. We systematically searched PubMed, Scopus, Cochrane, and Web of Science until December 2024. We included cohort and case-control studies that reported risk ratios (RRs), odds ratios (ORs), or hazard ratios (HRs) with 95% confidence intervals (CIs). The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the included studies. Overall, 26 observational studies (15 case-control and 11 cohort) showed no significant associations between TFA, MUFA, PUFA, or SFA intake and PC risk. However, case-control studies indicated a significant positive association for SFA intake (OR: 1.43; 95% CI: 1.02-1.99) and an inverse association for PUFA intake (OR: 0.74; 95% CI: 0.59-0.94). No significant relationship was found for TFA or MUFA intake in case-control studies. Stratification by study design was conducted to address differences in bias, such as recall bias in case-control studies and longer follow-up periods in cohort studies. Our findings suggest that modifying dietary fatty acid intake may contribute to PC prevention. These results highlight the need for further research to confirm these associations, explore underlying mechanisms, and examine the impact of dietary patterns and fatty acid sources on PC risk.\n\nID: 42432727\nTitle: Dietary patterns and exploratory gut microbiota profiles associated with diabetic retinopathy and cognitive impairment in type 2 diabetes.\nAbstract: Diabetic retinopathy (DR) and cognitive impairment are closely related complications of type 2 diabetes mellitus (T2DM). Although dietary patterns and gut microbiota have each been linked to these conditions, their combined associations with co-occurring DR and cognitive impairment remain unclear. This study examined dietary patterns and exploratory gut microbiota profiles in relation to co-occurring DR and cognitive impairment in patients with T2DM. In this cross-sectional study, 306 patients with T2DM were classified into four groups: no DR with normal cognition (DMCN), no DR with cognitive impairment (DMCI), DR with normal cognition (DRCN), and DR with cognitive impairment (DRCI). Dietary patterns were derived using principal component analysis. Gut microbiota composition was assessed using 16 S rRNA sequencing in a subset of 108 participants. Multinomial logistic regression was used to examine associations between dietary patterns and group classification, and microbiome analyses included diversity, taxonomic composition, exploratory differential abundance, and diet-microbiota correlations. Four dietary patterns were identified. In fully adjusted models, DP-I and DP-II were associated with higher odds of DMCI and DRCI, respectively, whereas DP-III was associated with lower odds of both DMCI and DRCN. DP-IV showed no significant association. Gut microbiota analyses showed modest but statistically significant group-related differences in community structure, with partial overlap across groups. Exploratory LEfSe analysis identified group-associated taxa, including higher relative abundances of Bifidobacterium, Streptococcus, and Dubosiella in DMCN and of Pseudomonas, Bilophila, and Sarcina in DRCI. However, these genus-level differences were not significant after covariate-adjusted MaAsLin2 analysis with false discovery rate (FDR) correction. Nominal diet-microbiota correlations were observed but were not statistically robust after FDR correction. Dietary patterns were associated with clinical group classification based on DR and cognitive impairment in patients with T2DM. Gut microbiota analyses suggested modest, exploratory group-related differences, but diet-microbiota correlations were not statistically robust after FDR correction. These cross-sectional findings should be interpreted as hypothesis-generating and require validation in larger longitudinal studies.\n\nID: 42431670\nTitle: Complementary feeding indicators among children aged 6-23 months: a cross-sectional study assessing minimum dietary diversity, minimum acceptable diet and dietary patterns in Njombe Town Council, Tanzania.\nAbstract: This study assessed the minimum dietary diversity (MDD), minimum meal frequency (MMF), minimum acceptable diet (MAD) and dietary patterns among children aged 6-23 months in Njombe Town Council. Community-based cross-sectional study. This study was conducted in the Njombe Town Council, which is located in the Njombe region in the southern part of Tanzania. A total of 330 caregivers of children aged 6-23 months were recruited using a multistage probability sampling technique. Data were collected from January to March 2021 using a structured questionnaire adapted from the Process for Promotion of Child Feeding (ProPAN) manual. None. The primary outcomes were the prevalence of MDD, MMF and MAD, assessed according to the 2021 WHO infant and young child feeding indicators. Secondary outcomes included food group consumption and dietary patterns identified using principal component analysis. A total of 330 caregivers of children aged 6-23 months participated in the current study. Nearly half (43.9%; n=145) were aged between 30 and 49 years, with a mean age of 30.28 years and an SD of ±6.119 years. Only 26.36% of children aged 6-23 months achieved MDD, 71.5% achieved MMF and 18.48% met MAD, with a mean dietary diversity score of 3.35±1.6. Predominant foods included grains, roots and tubers (80.91%) and breast milk (90%), while dairy products were the least consumed (7.27%). Three dietary patterns emerged: cereals, roots and tubers; dairy products and eggs; and vitamin A-rich fruits and vegetables. The MDD and MAD attainment in Njombe Town Council are suboptimal, reflecting reliance on staple foods and limited nutrient-rich options. These findings highlight the need for context-specific interventions, including strengthened nutrition education, promotion of diversified diets and agricultural strategies that improve access to nutrient-dense foods to enhance infant and young child nutrition.\n\nID: 42431462\nTitle: Non-advanced age-related macular degeneration: current concepts and future perspectives.\nAbstract: Non-advanced age-related macular degeneration (AMD), encompassing early and intermediate stages, represents a critical therapeutic window before irreversible central vision loss. Traditionally defined by drusen size and pigmentary abnormalities on color fundus photography, disease characterization has evolved substantially with the integration of multimodal imaging biomarkers. Contemporary imaging enables detailed structural phenotyping, including reticular pseudodrusen (also known as subretinal drusenoid deposits), hyperreflective foci, and incomplete retinal pigment epithelium and outer retinal atrophy, which refine risk stratification and provide insight into progression toward advanced disease. Functional assessment has expanded beyond best-corrected visual acuity to include low-luminance visual acuity, contrast sensitivity, dark adaptation, and microperimetry, many of which are more sensitive to early dysfunction. However, standardization and regulatory approval of these endpoints remain ongoing challenges. Non-advanced AMD arises from complex interactions among genetic susceptibility, aging, environmental exposures, and systemic metabolic factors. Smoking remains the strongest modifiable risk factor, while Mediterranean dietary patterns appear protective. Currently, no pharmacologic therapies are approved for non-advanced AMD. The Age-Related Eye Disease Study formulations remain the only interventions proven to reduce progression in high-risk individuals. Emerging approaches, including subthreshold laser therapy and photobiomodulation, show preliminary promise but require validation in robust and adequately powered randomized clinical trials. Recent consensus efforts emphasize biomarker-driven classification and highlight the heterogeneity of AMD phenotypes across populations. Future research priorities include validation of quantitative imaging and functional endpoints, integration of artificial intelligence-based predictive models, and development of targeted therapies to delay progression. These endevours will be essential to advance precision prevention strategies.\n\nID: 42431320\nTitle: Temporal changes in Mediterranean-style diet adherence and ultra-processed food exposure in relation to psychological distress at follow-up: A 12-year analysis of the Melbourne collaborative cohort study.\nAbstract: Consuming a Mediterranean-style diet is associated with lower depression risk. Concurrently, the ultra-processed food (UPF) dietary pattern is associated with increased depression risk. As dietary patterns shift over time, it is important to understand how changes in these dietary patterns relate to psychological distress as an indicator of depression. We used a subset of data from the Melbourne Collaborative Cohort Study (n = 21,718). Dietary intake was assessed at baseline and follow-up using food frequency questionnaires, from which Mediterranean diet scores and UPF intake were derived. Psychological distress at follow-up was measured using the Kessler Psychological Distress Scale (K10). We assessed change in diet from baseline to follow-up using generalised estimating equations to account for repeated measures, and associations of change in diet with depression using Poisson regression. Analyses were conducted in the overall sample and by birthplace (Australian/New Zealand/Northern European; Southern European). Participants increased both their adherence to the Mediterranean-style diet (β = 0.28, 95%CI = 0.25-0.31) and exposure to UPFs (β = 55.20 g/day, 95%CI = 51.71-58.69). Stratification by birthplace showed similar patterns, except for Southern European participants where no clear change in UPF exposure was observed (β = -2.38 g/day, 95%CI = -12.35-7.59). One-point increases in Mediterranean diet score between baseline and follow-up were associated with a 5% lower risk of psychological distress (RR = 0.95, 95%CI = 0.93-0.98), while increasing UPF by 90 g/day was associated with a 5% higher risk (RR = 1.05, 95%CI = 1.03-1.07). Adherence to Mediterranean-style diet and UPF exposure increased over time across the overall sample, although patterns varied by region, and these changes were associated with opposing risks of psychological distress.\n\nID: 42431155\nTitle: Predictors of food waste quantities and composition: A nationwide diary study of Swiss households.\nAbstract: In this study, we aimed to quantify the average amount of avoidable food wasted in Swiss households using a novel web-based diary method. We also aimed to identify under-explored predictors of food waste, including sociodemographic factors (e.g. linguistic region), psychological factors (e.g. plate-clearing tendencies and perceived health risk), and eating habits (e.g. dietary patterns and frequency of dinner preparation). We collected data from a random stratified sample of 515 households in Switzerland across three linguistic regions. Food waste data for 14 food groups were collected via a web application, whereas personal and household characteristics were gathered separately through online surveys. We identified food waste predictors using correlation and regression analyses. On average, the participants reported wasting 401.9 grams (standard deviation = 394.3) of food per capita per week. Overall, age, household size, linguistic region, and plate-clearing tendencies were key predictors of food waste. Households in Italian-speaking regions wasted less food than those in German-speaking regions. Additionally, participants with stronger plate-clearing tendencies wasted less food than those with weaker tendencies. This finding might thus highlight a relevant trade-off between reducing food waste on plates and increased overeating (metabolic food waste), which may result from a stronger tendency to clear one's plate. We also observed that 'non-meat eaters' generated more waste of starchy side dishes than 'meat eaters'. Our findings highlight the need for future interventions to address cultural, behavioural, and dietary factors to reduce avoidable food waste and offer insights for designing targeted strategies for specific populations and food categories.\n\nID: 42430329\nTitle: Examining relationship between unhealthy lifestyle and life satisfaction among new students at Tehran University of Medical Sciences.\nAbstract: Transitioning to university is a critical period marked by lifestyle changes, academic pressures, and increasing autonomy, which can influence students' overall well-being. Previous research suggests that unhealthy lifestyle behaviors-including poor diet, insufficient physical activity, inadequate sleep, and ineffective stress management-may negatively impact life satisfaction among young adults. This cross-sectional study examined the relationship between lifestyle and life satisfaction among newly enrolled undergraduate students at Tehran University of Medical Sciences in 2024. Participants completed structured questionnaires assessing multiple lifestyle domains (diet, physical activity, sleep, smoking, alcohol use) and life satisfaction using validated Iranian questionnaires. Lifestyle scores were categorized as \"healthy\" or \"unhealthy,\" and life satisfaction as \"good\" or \"poor.\" Associations were analyzed using Pearson's chi-square test and multivariable logistic regression, adjusting for age, sex, socioeconomic status, and anxiety. Overall, of the 419 students, 294 (70.2%) reported good life satisfaction. Socioeconomic status and anxiety levels differed significantly across life satisfaction groups (p < 0.001). Students with healthier dietary patterns reported higher life satisfaction (76.6% vs. 60.4%, p = 0.02). Multivariable analysis indicated that students with healthy lifestyles had significantly higher odds of good life satisfaction compared to those with unhealthy lifestyles (adjusted odds ratio [aOR = 1.91; 95% confidence interval [CI]: 1.10,3.35; p = 0.02). Each one-unit increase in lifestyle score was associated with a 28% increase in the odds of good life satisfaction (aOR = 1.28; 95% CI: 1.05,1.57; p = 0.02). Unhealthy lifestyle behaviors are negatively associated with life satisfaction among new university students. Interventions promoting balanced nutrition, regular physical activity, adequate sleep, and overall health-conscious behaviors may enhance students' life satisfaction and well-being.\n\nID: 42430158\nTitle: Eco-Focused Menu Labels on Full Meal Orders From Fast-Food Restaurants: A Randomized Clinical Trial.\nAbstract: Promoting environmentally sustainable dietary patterns can benefit both population and planetary health. Ecolabels on restaurant menus could promote healthful and sustainable choices, but evidence is needed on effects in different restaurant types. To test the effects of different ecolabel designs on menus from 2 fast-food restaurants on the healthfulness of full meal orders, compared to a control label. This randomized clinical trial was conducted online in a nationally representative sample of adults (≥18 years) in the US in April 2025. Participants were recruited from the NORC AmeriSpeak survey panel to participate in this experiment. Participants were randomized via an automated process within the survey platform to 1 of 5 label conditions: (1) control: QR code; (2) low-climate-impact labels; (3) traffic-light labels (TLLs); (4) high-climate-impact labels; or (5) grade-scale labels and asked to order lunch from 2 fast-food menus (1 burger-focused and 1 sandwich-focused). The primary outcome was the healthfulness of meals ordered based on a modified Nutrient Profile Index (NPI) score. Other outcomes included the estimated greenhouse gas emissions (GHGE), calorie and nutrient content, and cost of selected meals, as well as perceptions of labels and knowledge about the climate contribution of different foods. Among the 6210 participants (3274 [51.0%] women; mean [SD] age, 48.1 [18.1] years), 1236 participants were randomized to the control group; 1249 to low-climate-impact labels, 1243 to high-climate-impact labels, 1235 to TLLs; and 1247 to grade-scale labels. Demographic characteristics were similar across groups. Only the TLL was effective at promoting more healthful food choices in the burger restaurant compared to the control label (mean [standard error] NPI score: 49.93 [0.18] points vs 49.25 [0.18] points; P < .001). There were no ecolabel effects on NPI score in the sandwich restaurant. Compared to control, the TLL led to 15.2% lower GHGE for meals in the burger restaurant and 29.8% lower GHGE for meals in the sandwich restaurant. The TLL was the most noticeable (78.30% [95% CI, 75.35%-81.26%]; P < .001) and had the highest percentage of participants who correctly reported what the label was about (88.72% [95% CI, 86.04%-91.39%]; P < .001). There were no differences in the overall cost of the meals selected by label condition. Findings from this web-based randomized clinical trial showed that TLL-style ecolabels on restaurant menus may be an effective strategy to promote more sustainable and, in some instances, more healthful food choices without increasing consumer costs. ClinicalTrials.gov Identifier: NCT06909019.\n\nID: 42429521\nTitle: A Systematic Review and Meta-analysis on the Salt and Sodium Intake in India.\nAbstract: In India, estimates of salt intake vary widely due to cultural and regional dietary patterns, and an updated comprehensive synthesis was lacking. The objective of this study is to estimate the pooled mean salt and sodium intake and the prevalence of high salt intake across diverse Indian populations, and to explore regional, demographic, and temporal variations. A comprehensive literature search was conducted across PubMed, Scopus, Web of Science, and Embase until December 2, 2024, following PROSPERO registration (CRD42024618201). Studies reporting mean salt or sodium intake or the prevalence of excess intake were included in the study. A random-effects meta-analysis was conducted, and heterogeneity was assessed using the I² statistic. Subgroup analyses were performed by region, locality, sex, hypertension status, and study year. Eighty-three studies were included in the study. The pooled mean salt intake from 30 studies was 9.01 g/day (95% confidence interval [CI]: 8.23-9.79), whereas the mean sodium intake from 23 studies was 3.49 g/day (95% CI: 2.72-4.25), both exceeding the World Health Organization-recommended limits. The pooled prevalence of high salt intake was 61% (95% CI: 48%-73%), with wide variation by intake definition. Subgroup analyses showed higher intake in rural populations, males, and hypertensive individuals. Salt and sodium intake in India remains significantly above recommended levels, with considerable variability across regions and populations.\n\nID: 42429437\nTitle: Food practices and nutritional coping strategies of university students during Sri Lanka's economic crisis: An online survey.\nAbstract: BackgroundThe recent global economic crisis has doubled poverty levels, yet its impact on university students' dietary behaviours remains underexplored.ObjectiveTo investigate the food practices and nutritional coping strategies employed by university students during the prevailing economic crisis in Sri Lanka.MethodsAn online-based cross-sectional survey was conducted with 206 students from a selected university. The questionnaire contained demographic information, a seven-day dietary recall, financial characteristics, and nutritional coping strategies among university students. Descriptive statistics and multivariate logistic regression analyses were performed using the Statistical Package for the Social Sciences version 30.0 to explore the association between selected economic factors and food choice outcomes among the participants.ResultsThe sample consisted of 52.9% females, with the majority of participants falling within the 23-25-year age group. A significant portion (64.6%) reported a reduction in household income over the past three months, and 84.0% had adopted cost-cutting strategies to manage household finances. Notably, 93.7% of students had reduced their university-related expenses, including food (66.5%). Nutritional coping strategies included replacing main meals with low-cost snacks (84.5%) and switching to bakery items (53.4%). Multivariate logistic regression analysis revealed that students who reduced spending on university-related expenses were 2.5 times more likely to consume bakery items (odds ratio (OR) = 2.21; 95% confidence interval (CI): 0.275-6.61; p < 0.05), while the odds of consuming low-cost starchy food were 2.3 (OR = 2.30; 95% CI: 1.14-4.79; p < 0.05) among those who reduced household income.ConclusionThis study demonstrates that a reduction in household income and adjustments to household and university-related expenditures during Sri Lanka's economic crisis were associated with less favourable dietary patterns among undergraduate students and with the use of nutritional coping strategies that may compromise dietary adequacy.\n\nID: 42428758\nTitle: Health literacy, dietary behavior and body mass index in male and female Norwegian conscripts. A cross-sectional study.\nAbstract: Health literacy (HL) is an important determinant of health behaviors, including diet. In military populations, optimal nutrition is critical for physical performance, readiness, and long-term health. In Norway, first-time military service provides a unique opportunity to influence young conscripts' health habits. This study investigates the relationship between HL and dietary patterns, body mass index (BMI), and meal adherence among Norwegian conscripts, with an emphasis on potential sex differences. A cross-sectional study. This cross-sectional study included Norwegian conscripts completing first-time military service. HL was measured using the validated HLS-Q12 instrument. Dietary behaviors, meal patterns, and BMI were assessed using self-reported questionnaire data. A digital questionnaire was sent to Norwegian conscripts completing their first-time military service in 2022 (n=9,991). A total of 2,225 conscripts consented to participate in the study. The survey assessed dietary habits across different military settings, self-reported diet quality, and HL using the HLS-Q12 tool. BMI was calculated from self-reported height and weight. Statistical analyses included chi-square tests and Pearson correlation to explore associations between HL, diet, and BMI. Significant associations were observed between HL and several dietary variables; however, most associations were weak in magnitude. Higher HL was associated with more regular meal patterns and better self-reported diet quality. Additionally, differences between sexes were observed, but effect sizes were generally small. More than half of conscripts had an adequate HL, with males scoring significantly higher than females. Conscripts with adequate HL were more likely to rate their diet as good, follow meal recommendations, and maintain a normal BMI. However, no significant association between HL and BMI was found in the total population; differences appeared in sex-stratified analyses, among female conscripts. Independently of HL, unhealthy snacking and high-sugar drink consumption were more common during field training, whereas conscripts with inadequate HL (iHL) reporting higher sugary snack intake at home. Adequate HL was weakly but significantly correlated with higher self-reported diet quality, more frequent adherence to regular meals, and lower sugary snack consumption. This could mean that HL was associated with self-reported dietary intentions but not outcomes like BMI. HL may be associated with dietary behaviors among conscripts. However, given the weak associations and study limitations, the findings should be interpreted with caution. Although more than half of the conscripts had adequate HL, iHL was prevalent among Norwegian conscripts. Poorer self-reported diet quality and lower adherence to regular meal patterns is associated with iHL, particularly during field training. No significant associations was found between HL and BMI. The findings suggest a need for tailored education to improve HL and behavior change, to promote healthier dietary habits during military service.\n\nID: 42428198\nTitle: Methodological Considerations in Meta-Analyses Examining Irregular Dietary Patterns and Esophageal Cancer Risk.\nAbstract: Irregular dietary patterns have been linked to an increased risk of esophageal cancer in observational meta-analyses. However, methodological limitations may influence the strength and interpretation of these associations. This editorial highlights key concerns, including substantial between-study heterogeneity, inconsistent definitions of dietary irregularity, limited power to assess publication bias, and residual confounding inherent to observational research. Variability in esophageal cancer subtypes and cultural dietary practices further complicates pooled risk estimation. While existing evidence underscores the potential relevance of meal regularity in cancer prevention, cautious interpretation is warranted. Future studies using standardized exposure definitions and subtype-specific analyses are needed to improve the reliability of meta-analytic findings.\n\nID: 42425454\nTitle: Effect of Carbohydrate-Restricted Dietary Patterns Based on Prescribed and Self-Reported Intake in Adults with Overweight and Obesity: A Systematic Review and Meta-Analysis.\nAbstract: Carbohydrate (CHO) restriction has regained attention as a dietary approach for weight management and cardiometabolic health, though evidence supporting its effectiveness remains controversial, particularly regarding degree of restriction. Examine effects of CHO-restricted versus higher CHO dietary approaches on weight- and cardiometabolic-related outcomes in adults with overweight or obesity without other established disease. Searches of MEDLINE, CINAHL, and Cochrane databases identified relevant randomized controlled trials (RCTs) published from 2010-2025. Primary outcomes were anthropometric outcomes (body weight, BMI, waist circumference, fat and lean body mass) and glycemic outcomes (fasting blood glucose, HbA1c). Meta-analyses were conducted using random-effects models for an outcome of interest. Heterogeneity was assessed using I2, evidence certainty using the GRADE methodology, and publication bias was assessed using Begg and Egger's statistic and by generating funnel plots. Twenty-three RCTs, represented in 28 articles, were included. Degree of CHO restriction varied across studies, with self-reported intake often less restrictive than prescribed levels. CHO restriction resulted in modest but significant reductions in body weight (Mean difference (MD): -1.32kg, 95% CI: -2.03, -0.61), waist circumference (MD: -0.89 cm, 95% CI: -1.44, -0.34), and fat mass (standardized mean difference (SMD): -0.29, 95% CI: -0.48, -0.10) compared to higher CHO diets. CHO restriction reduced fasting blood glucose (MD: -0.08mmol/L, 95% CI: -0.17, 0.00), HbA1c (MD: -0.16%, 95% CI: -0.28, -0.04), triglycerides (MD: -0.17mmol/L, 95% CI: -0.26, -0.08), and systolic blood pressure (MD: -4.86mmHg, 95% CI: -6.60, -3.11). CHO restriction (<45% total daily energy intake) likely provides modest benefits for weight management and certain cardiometabolic risk factors in adults with overweight or obesity.\n\nID: 42424249\nTitle: Development and validation of a food group system for intake control in people with diabetes: SMARTCLOTH-Database.\nAbstract: This study presents the development and validation of the SMARTCLOTH-Database, a structured food group system designed to support dietary management for individuals with diabetes. The database organises foods into 20 nutritionally coherent groups, distinguishing between raw and cooked forms, based on Spanish dietary patterns and statistical criteria. Nutritional values were calculated using weighted averages derived from national food consumption data and multiple international food composition databases. To validate the system, a computational tool was developed to generate daily menus automatically and compare nutritional outputs against a gold standard reference (BDCA). The comparison showed small mean differences (less than ±22 kcal, < 2 g carbohydrates, < 0.6 g protein, and <1.5 g lipids), with high concordance demonstrated through intraclass correlation coefficients (ICC ≥ 0.75) for carbohydrates and proteins across most analyses. These results indicate that the SMARTCLOTHDatabase provides accurate and reliable estimates of macronutrient content, making it suitable for integration into digital tools aimed at improving dietary self-management in people with diabetes.\n\nID: 42422989\nTitle: Association between dietary index for gut microbiota and all-cause and cardiovascular disease mortality in patients with gout and hyperuricemia: A prospective cohort study.\nAbstract: ObjectiveGout and hyperuricemia (HUA) are common metabolic disorders associated with increased all-cause and cardiovascular disease (CVD) mortality, and gut microbiota-modulating diets may influence prognosis. We aimed to evaluate whether the Dietary Index for Gut Microbiota (DI-GM) is associated with all-cause and CVD mortality among adults with gout or HUA.MethodsIn this prospective cohort study, we analyzed data from 5,325 adults with gout or hyperuricemia enrolled in the 2007-2018 National Health and Nutrition Examination Survey (NHANES). DI-GM scores were calculated using 24-hour dietary recall data, incorporating 14 predefined food components (10 beneficial and 4 harmful to gut microbiota). Mortality status was ascertained through linkage to the National Death Index up to December 31, 2019. Cox proportional hazards models were applied to estimate hazard ratios and 95% confidence intervals, adjusting for demographic, lifestyle, and clinical factors. Sensitivity analyses, interaction tests, and stratified analyses were conducted to assess robustness.ResultsDuring a median follow-up of 6.5 years (35,625 person-years), 603 deaths occurred, including 197 from CVD. Higher DI-GM scores were associated with significantly lower mortality risk. Participants with DI-GM scores ≥6 had a 33% reduced risk of all-cause mortality and a 45% reduced risk of CVD mortality compared to those with scores ≤ 4. Each one-point increase in DI-GM score was associated with an 8% decrease in all-cause mortality and a 13% decrease in CVD mortality. Results were consistent across all sensitivity analyses.ConclusionsIn individuals with gout or hyperuricemia, higher DI-GM scores were independently associated with reduced all-cause and CVD mortality. These findings suggest that gut microbiota-friendly dietary patterns may provide prognostic value and offer a potential target for dietary interventions in this high-risk population.\n\nID: 42422404\nTitle: Diet Quality, Dietary Inflammatory Potential, and All-Cause Mortality in U.S. Adults With Asthma-COPD Overlap.\nAbstract: Asthma-COPD overlap (ACO) is associated with increased mortality and disease burden compared to asthma or COPD alone. Diet, a modifiable risk factor, influences inflammation and lung health, yet its impact on ACO mortality remains understudied. This study investigates the synergistic effects of the Healthy Eating Index (HEI-2015) and Dietary Inflammatory Index (DII) on all-cause mortality in ACO patients. Using data from the National Health and Nutrition Examination Survey (NHANES) 2007-2018, we analyzed 609 U.S. adults with ACO, defined by clinical and spirometric criteria. Dietary patterns were assessed via HEI-2015 (diet quality) and DII (inflammatory potential). Cox proportional hazards models evaluated associations with mortality, adjusting for sociodemographic, lifestyle, and clinical confounders. Restricted cubic spline analyses explored non-linear relationships, and Least Absolute Shrinkage and Selection Operator (LASSO) regression identified key dietary components for a prognostic nomogram. Healthier diets (higher HEI-2015) were associated with lower mortality risk (HR = 0.98, 95% CI: 0.97-0.99, highest quartile), while pro-inflammatory diets (higher DII) increased risk (HR = 1.13, 95% CI: 1.04-1.22). The combination of healthy and anti-inflammatory diets showed the strongest protective effect (HR = 0.68, 95% CI: 0.47-0.98). LASSO regression identified PUFA, total dairy, whole fruit, and n-6 fatty acids as key predictors, incorporated into a nomogram with moderate predictive accuracy (AUC: 0.64-0.67). Kaplan-Meier curves confirmed better survival in low-risk dietary groups (p < 0.0001). Subgroup analyses showed stronger effects in mild drinkers and non-hypertensive patients. High-quality, anti-inflammatory diets synergistically reduce mortality in ACO patients. Targeted nutritional interventions emphasizing whole fruits, dairy, and healthy fats may improve outcomes. Future research should validate these findings through interventional trials.\n\nID: 42420952\nTitle: Association between food-based dietary inflammatory index and dental health: results from Bandare-Kong Non-Communicable Disease (BKNCD) cohort.\nAbstract: Oral health is strongly related to diet, and pro-inflammatory dietary patterns may worsen dental diseases through systemic inflammation. This study examined the relationship between the Food-based Dietary Inflammatory Index (FDII) and dental health, assessed by the DMFT index (Decayed, Missing, and Filled Teeth index), in Iranian adults. This cross-sectional study analyzed baseline data from the Bandare-Kong cohort, a subset of the prospective PERSIAN study, including 3,630 Iranian adults aged 35-75 years. Dietary intake was assessed using a validated food frequency questionnaire, and FDII was used to assess the inflammatory potential of participants 'dietary patterns. Participants were classified into tertiles based on their E-FDII scores. The DMFT index was calculated as the sum of decayed, missing (due to caries), and filled permanent teeth. Generalized linear regression models (GLR) were used to examine the association between FDII scores and dental health outcomes. In the total population, higher dietary inflammatory potential was suggestively associated with poorer oral health. Compared with T1, T2 and T3 of E-FDII were related to fewer teeth [β = - 0.9 (-1.2 to - 0.6) and - 1.0 (-1.5 to - 0.8)], a higher number of decayed teeth [0.3 (0.1 to 0.5) and 0.4 (0.2 to 0.8)], more missing teeth [0.9 (0.6 to 1.3) and 1.1 (0.8 to 1.4)], and higher DMFT scores [1.1 (0.6 to 1.5) and 1.5 (1.0 to 1.9), p-trend = 0.001] in the adjusted model, while the number of filled teeth showed no clear association. Stratified analyses indicated that these suggestive trends were more apparent in women and middle-aged adults. Our findings indicate that higher diet-related inflammatory potential is associated with poorer dental health in a representative sample of Iranian adults. Given the small effect sizes, the clinical relevance may be limited. Longitudinal studies are warranted to clarify the temporal relationship and underlying mechanisms.\n\nID: 42419343\nTitle: Nutritional, functional, and psychological considerations for incretin-based therapies in adults-an EASO, EFAD, and ECPO Consensus Statement.\nAbstract: Incretin-based therapies, including GLP-1 receptor agonists and dual GLP-1-GIP receptor agonists, have transformed obesity management, producing substantial weight loss and cardiometabolic benefits, with potential improvements in obesity-related complications, physical function, quality of life, and psychological wellbeing for many individuals. However, reduced appetite, rapid weight loss, gastrointestinal adverse effects, and changes in eating behaviour might create nutritional, functional, or psychological risks in some individuals. This EASO-EFAD-ECPO Consensus Statement outlines pragmatic nutritional, functional, and psychological considerations during incretin-based therapy treatment. We synthesise evidence on medical nutrition therapy, including protein targets during weight loss, dietary quality, and mitigation of gastrointestinal adverse events. We discuss pragmatic approaches that could help support preservation of fat-free mass and physical function during weight loss, including adequate protein intake and progressive resistance exercise. We emphasise the psychological and identity-related challenges during incretin-based therapy, including shifts in food reward, coping, and social connection, and recommend psychological screening, with integrated support where needed. We propose pragmatic monitoring during weight loss, including diet quality, micronutrient risk, and functional measures, with body-composition assessment where indicated. We suggest approaches to address disparities in access and adherence to ensure equity. We discuss the importance of shared decision making with the patient in decisions to start, up-titrate, delay, pause, down-titrate, or discontinue incretin-based therapies, considering the physical and psychological risks of treating versus not treating. Finally, we identify future research priorities, including longitudinal research on micronutrient status, macronutrient requirements, changes in dietary patterns and food choices, musculoskeletal outcomes, unique dosing schedules, and post-cessation maintenance to optimise safety, efficacy, and the patient experience.\n\nID: 42419161\nTitle: Dietary patterns and Alzheimer's disease: East-west perspectives and future intervention strategies.\nAbstract: Among various modifiable risk factors, dietary patterns (DPs), as a holistic lifestyle intervention, have become a focus of current research due to their protective effects on cognitive health. Classic Western DPs, such as the Mediterranean diet (MedDiet), have been widely confirmed to effectively improve cognitive function, thereby reducing the risk of Alzheimer's disease (AD). However, existing evidence mainly concentrates on Western populations and their DPs, including the MODERN (Machine learning-assisted Optimizing Dietary intERvention against demeNtia risk) diet optimized using machine learning. Given the significant differences in food types, dietary habits, and cooking methods among Asian populations, research on localized DPs optimized for cognitive health in Asian populations remains insufficient. In this context, the team at the Department of Geriatrics, Shanghai Sixth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine has taken the lead in systematically defining the Shanghai Cognitive Diet Pattern (SCDP). This review aims to comprehensively outline the core features and potential biological mechanisms relevant to AD in both classic Western DPs and the emerging East Asian DP. Subsequently, this review will systematically compare Eastern and Western DPs. In conclusion, this review proposes shifting​ dietary strategies from population-level adaptation to individual precision, in conjunction with multimodal lifestyle management, and offers novel strategies for the prevention and management of AD.\n\nID: 42436161\nTitle: Dietary glucoraphenin ameliorates obesity and steatotic liver disease associated with gut dysbiosis induced by a Western diet in mice.\nAbstract: Western-style diets promote obesity, gut dysbiosis, and metabolic dysfunction-associated steatotic liver disease (MASLD). In this study, glucoraphenin (GRE), the major glucosinolate in radish (Raphanus sativus L.) greens and sprouts, was evaluated for its effects on Western diet (WD)-induced metabolic derangements and gut dysfunction in mice. Intaking of 1 mg/kg body weight of GRE with WD for 8 weeks caused significant reductions in adipogenesis indicators such as body weight gains, adipocyte hypertrophy, and serum leptin level. This result was further proved by significant changes in lipogenesis and lipolysis-related protein expressions in adipocyte. Administration of GRE also suppressed development of MASLD, which was observed through reductions in serum ALT and AST and suppressions the expression of FAS, SREBP1, mTOR, SCD1, ACC, and ChREBP in liver tissues. GRE administration effectively prevented the decrease in the gut microbial richness and diversity caused by WD and recovered serum branched-chain amino acids and microbiota-derived purine metabolites (inosine and hypoxanthine). These findings indicate that GRE mitigates WD-induced obesity and MASLD via coordinated regulation of lipid metabolism and the gut-liver axis.\n\nID: 42418776\nTitle: Nutrition Therapy in Critically Ill Adults.\nAbstract: In the acute phase of critical illness, adults have severe catabolism, inflammation, muscle loss, and gut dysfunction, all of which shape nutritional requirements. Early enteral nutrition supports gut integrity and microbiome health, but trials have shown that early short-term parenteral nutrition is a safe alternative when enteral feeding is not possible. Large trials have shown that early full-dose energy delivery offers no benefit over restrictive dosing and may increase gastrointestinal and metabolic complications, findings that support a restrictive nutrition strategy, especially in patients who have circulatory shock or are at risk for refeeding syndrome. Similarly, large trials have shown no advantage of high-dose over standard-dose protein and suggest harm in patients with acute kidney injury. Because adverse events are common with enteral nutrition, safe nutrition delivery requires gradual advancement, strategies for prevention of refeeding syndrome, glycemic control, and avoidance of routine gastric residual volume monitoring. Patient heterogeneity underscores the need for precise, biomarker-guided, phase-specific nutrition to preserve lean muscle mass and improve recovery.\n\nID: 42345436\nTitle: Management of Sensorineural Hearing Loss in Adults: Consideration of Lifestyle Practices from a Mitochondrial Perspective.\nAbstract: The physiological processes of sensorineural hearing in the cochlea have high energy demands. As energy is provided mainly by mitochondria housed in cochlear cells, mitochondrial dysfunction can possibly lead to sensorineural hearing loss (SNHL). Consequently, hearing benefits can potentially be derived if measures that can potentially enhance mitochondrial health are implemented. Unhealthy lifestyle practices have led to an increased risk of developing systemic oxidative stress and chronic inflammation. These, in turn, may result in persistent mitochondrial dysfunction in the body. Together, they could possibly lead to the development of SNHL and other non-communicable chronic diseases (NCDs). Factors such as micro-nutrient deficiencies, obstructive sleep apnea, and gut dysfunction could result in mitochondrial dysfunction. On the other hand, mitochondrial function could be enhanced by interventions such as better food choices and hormetic strategies like intermittent fasting. Conventional treatments of SNHL focus on steroid therapy in acute loss and hearing rehabilitation with hearing devices in chronic loss. By integrating personalized healthy lifestyle strategies, it is postulated that the chances of hearing recovery in acute SNHL could be enhanced in some patients. In chronic SNHL, they could help to prevent/slow down its progression and possibly also the progression of concomitant NCDs. Further research is warranted to substantiate these postulations.\n\nID: 42327764\nTitle: Trained immunity as a systemic bridge: the liver-gut-immune-oral axis in the comorbidity of chronic liver disease and periodontitis.\nAbstract: Trained immunity (TI) reveals that innate immune cells acquire long-term functional memory through metabolic and epigenetic reprogramming. This review examines TI in chronic liver diseases and periodontitis, proposing the \"Liver-Gut-Immune-Oral Axis\" as a framework where TI bridges these comorbidities. The forward pathway, currently inferred from mechanistic and associative studies, proposes that liver-gut dysfunction induces bone marrow training, generating hyper-reactive monocytes that amplify periodontal inflammation. The reverse pathway, similarly conceptual, proposes that periodontal pathogens reprogram hematopoietic progenitors, accelerating liver disease progression. Both converge on shared metabolic-epigenetic reprogramming circuits. We emphasize that this axis represents a conceptual framework synthesized from current mechanistic and associative evidence; its validity as an integrated, causally-linked biological system awaits direct experimental validation. Targeting TI with metabolic modulators, epigenetic drugs, or periodontal interventions offers strategies to disrupt this cycle and advance precision medicine for inflammatory comorbidities.\n\nID: 42294883\nTitle: Astragalus polysaccharides ameliorate perinatal metabolic syndrome in sows via enhancing butyrate-producing bacteria.\nAbstract: Astragalus polysaccharide (APS), a bioactive phytomacromolecule from Astragalus membranaceus, exhibits anti-inflammatory, antioxidant, and immunomodulatory activities. Given mammals' lack of endogenous glycosidases for APS catabolism, this study hypothesizes its bioactivity stems from gut microbial interactions, investigating APS-mediated microbiome remodeling and therapeutic effects on perinatal metabolic syndrome (PeriMS) in sows. In vitro fermentation showed that APS significantly increased short-chain fatty acid (SCFA) production, with acetate (44.51 mmol/L), propionate (17.37 mmol/L), and butyrate (22.04 mmol/L) levels notably elevated and enriched canonical butyrate-producing taxa (g_norank_f_Muribaculaceae, g_Monoglobus, g_unclassified_f_Lachnospiraceae, P < 0.05). In vivo, gestational APS supplementation (from day 90) improved piglet weaning weight, reduced maternal backfat loss during lactation, shortened post-weaning estrus interval, elevated intestinal butyrate, alleviated systemic inflammation/oxidative stress, and mitigated PeriMS. Mechanistic analysis associated PeriMS improvement with butyrate-producing bacteria, with butyrate playing a key role in gut health enhancement. These findings establish APS as a prebiotic, highlighting the gut microbiota-SCFA axis as a therapeutic target for PeriMS. This study provides targeted mechanistic evidence that the gut microbiota-SCFA axis mediates PeriMS improvement by APS. Mechanistic analysis linked PeriMS improvement to butyrate-producing bacteria, with butyrate playing a key role in gut health enhancement, which was verified by a sodium butyrate rescue experiment. These findings establish APS as a prebiotic, highlighting the gut microbiota-SCFA axis as a therapeutic target for PeriMS. This work provides novel evidence for microbiota-SCFA axis involvement in sow perinatal metabolic health, offering translational strategies to improve livestock metabolic health through APS supplementation. In intensive pig farming, 40% of multiparous sows develop perinatal metabolic syndrome (PeriMS) around farrowing, causing $150-$200 annual loss per sow due to inflammation (e.g., higher IL-6), oxidative stress, and extended weaning-to-estrus intervals (2.1 days). Gut dysfunction-marked by fewer butyrate-producing bacteria and increased endotoxin-triggers barrier damage and inflammation. Supplementing with Astragalus polysaccharides (APS, 10 g/day) enhances beneficial bacteria like Muribaculaceae and butyrogenic Bacteroides, raising butyrate in vitro. In sows, APS lowers endotoxemia and gut inflammation (calprotectin), correlating with reduced postpartum IL-6 and reactive oxygen species. It also improves productivity: less backfat loss and heavier weaned piglets. By targeting gut-barrier crosstalk, APS breaks the inflammation-metabolism cycle, providing a sustainable alternative to antibiotics to enhance peripartum sow health and profitability.\n\nID: 42287941\nTitle: Dynamic dual roles of gut microbial metabolites in Alzheimer's disease: Translational insights for gut-brain axis interventions.\nAbstract: Alzheimer's disease (AD) is a complex neurodegenerative disorder in which the microbiome-gut-brain axis (MGBA) plays a crucial regulatory role through microbial metabolites. This review analyzes the concentration trajectories of representative metabolites across different disease stages and compartments, and synthesizes current preclinical evidence on how these metabolites influence AD pathogenesis, with particular attention to the mechanisms underlying their dual roles. We integrate evidence for bidirectional pathological crosstalk: gut dysbiosis accelerates central neurodegeneration through altered metabolite signaling, while AD-related neuropathology concurrently disrupts gut homeostasis. The review also evaluates MGBA-targeted intervention strategies and critically identifies key limitations that hinder clinical translation, including unclear dose-response relationships and insufficient patient stratification. We note that brain-to-gut mechanistic evidence remains considerably less developed than that for the gut-to-brain direction, and that signaling crosstalk among multiple metabolites is poorly characterized. Future studies should prioritize the neuroendocrine and immune pathways linking central pathology to gut dysbiosis, the dose-response relationships of individual metabolites, and standardized multi-metabolite profiling within prospective longitudinal cohorts. Addressing these gaps will advance mechanism-guided, precision-targeted interventions that mitigate the prevalent gut dysfunction in AD and confer global therapeutic benefits.\n\nID: 42258757\nTitle: Nonocclusive Mesenteric Ischemia in Cardiogenic Shock: Mechanisms of Splanchnic Hypoperfusion and Strategies for Early Detection.\nAbstract: Nonocclusive mesenteric ischemia (NOMI) is an underappreciated and lethal sequelae of cardiogenic shock (CS), forming the bulk of acute mesenteric ischemia in critically ill patients. In the setting of CS, reduced cardiac output, exposure to high doses of vasopressors, and nonpulsatile mechanical circulatory support (MCS) result in a \"perfect storm\" of hemodynamic insults to the splanchnic circulation. Mortality from NOMI in this population exceeds 70-90%, largely attributable to late diagnosis after irreversible transmural necrosis has already occurred. In this review, we describe the pathophysiology of NOMI in the setting of CS, considering the effects of sympathoadrenergic and renin-angiotensin mediated vasoconstriction, the loss of mesenteric pulsatility due to contemporary MCS, and the gut-heart axis as an enhancer of systemic injury. We address topics such as the under detection of limb ischemia with current imaging modalities, the potential of new markers of gut dysfunction, such as intestinal fatty acid-binding protein and citrulline, and bedside imaging, including contrast-enhanced ultrasound and assessment of portal vein pulsatility. We review strategies for prevention and management, including early MCS escalation, minimizing vasopressor requirements, and careful enteral feeding. Finally, we recognize the need for prospective multicenter registries and AI-based risk stratification to facilitate the diagnosis of this under-recognized condition. Understanding that the gut is not a \"mere\" bystander in the pathophysiology of CS, but rather a central participant, it may be the gateway to reducing the ongoing high mortality of this syndrome.\n\nID: 42254439\nTitle: Nutraceutical Interventions in Stunting: Advances, Challenges, and Prospects.\nAbstract: Childhood stunting remains a major global health challenge, reflecting the cumulative effects of inadequate nutrition, recurrent infection, and chronic intestinal dysfunction during early life. Beyond conventional micronutrient supplementation, nutraceutical interventions have emerged as complementary strategies to address the complex biological pathways underlying impaired linear growth. This review synthesizes current evidence on nutraceutical approaches to stunting, including improvements in macronutrient quality, bioactive food components, and microbiome-targeted strategies such as probiotics, prebiotics, synbiotics, postbiotics, and microbiota-directed foods. Evidence from clinical and preclinical studies indicates that nutraceutical effects on growth are generally modest and heterogeneous, with more consistent effects on weight gain than on height-for-age (HAZ). Variability in efficacy is strongly influenced by baseline nutritional status, environmental enteric dysfunction (EED), infection burden, dietary quality, and water, sanitation, and hygiene (WASH) conditions. Mechanistically, nutraceuticals may act through modulation of gut barrier integrity, inflammatory tone, microbial metabolism, and endocrine signaling pathways, particularly those involving the growth hormone-insulin-like growth factor-1 (GH-IGF-1) axis. Recent microbiota-directed food trials provide proof-of-concept that targeted correction of microbiome immaturity and gut dysfunction can support linear growth. Looking forward, advances in nutrigenomics, microbiome science, and epigenetics support a shift toward precision nutrition strategies that tailor interventions to biological responsiveness and context. Systems biology approaches integrating multi-omics data, network pharmacology, and interpretable artificial intelligence are expected to refine mechanistic understanding and guide intervention design. Effective translation will require rigorous trial designs, regulatory clarity, and integration of nutraceuticals within broader stunting reduction frameworks in low- and middle-income countries.\n\nID: 42167203\nTitle: Impact of Asymptomatic Enteroaggregative Escherichia coli Infection and Co-Pathogen Burden on Intestinal Barrier Function, Linear Growth, and Cognitive Development in Early Childhood: Insights from a Birth Cohort Study.\nAbstract: Enteroaggregative Escherichia coli (EAEC) is a major enteric pathogen in low-resource settings. The aim for the present study is to reanalyze the effects of subclinical EAEC infection, alone or in combination with other pathogens, on intestinal function, growth, and cognition in children aged 0-6 months through molecular diagnosis. A total of 1,659 non-diarrheal stool samples from the Etiology, Risk Factors and Interactions of Enteric Infections and Malnutrition and the Consequences for Child Health and Development cohort were analyzed using quantitative polymerase chain reaction testing for 29 enteropathogens. Children were grouped by infection status: EAEC alone or with 1, 2, or ≥3 co-pathogens. Enteroaggregative Escherichia coli and a higher pathogen burden were associated with lower socioeconomic status and greater antibiotic use (P <0.001). Enteroaggregative Escherichia coli with ≥3 co-pathogens was linked to elevated neopterin (β = 687.5; CI: 129.7-1,245.3), increased intestinal permeability (β = 0.41; CI: 0.058-0.77), and a lower length-for-age z-score (β = -0.44; CI: -0.76 to -0.12), and EAEC alone reduced cognitive scores at 15 and 24 months of age (β = -2.82 and -5.02, respectively; CI: -5.15 to -0.48 and -9.81 to -0.22, respectively). Subclinical EAEC infection is associated with inflammation, gut dysfunction, growth failure, and cognitive delay.\n\nID: 42092952\nTitle: Multi-omics analysis of deep brain stimulation associated with brain-gut axis modulation and symptom amelioration in a Parkinson's disease mouse model.\nAbstract: This study aimed to systematically elucidate the molecular mechanisms underlying PD-associated brain-gut dysfunction through multi-omics analyses and to evaluate the therapeutic potential of combined Deep Brain Stimulation (DBS) and Brain-Computer Interface (BCI) interventions. Transcriptomic and 16S rRNA datasets from Gene Expression Omnibus (GEO) and Sequence Read Archive (SRA) were integrated and analyzed using DESeq2, limma, Gene Set Enrichment Analysis (GSEA), and PICRUSt2 to identify disrupted pathways and microbial functional features. In the 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD mouse model, four groups (Normal, MPTP, MPTP + DBS, and MPTP + DBS+BCI) were assessed using behavioral testing, Local Field Potentials (LFP) recordings, molecular assays, and histological analysis. The findings revealed synaptic damage and metabolic pathway disruptions in PD brains, accompanied by reduced abundance of Short-Chain Fatty Acid (SCFA)-producing gut microbes. Combined DBS and BCI markedly improved motor deficits, suppressed aberrant β oscillations, restored gut barrier integrity and microbial homeostasis, and reduced pathological α-synuclein (αSyn) aggregation. Collectively, these results demonstrate that DBS + BCI is associated with improvements across neural, microbial and inflammatory readouts, supporting a correlative brain-gut-immune framework.\n\nID: 42051732\nTitle: Source-stratified gut-extraintestinal organ crosstalk in sepsis-associated acute gastrointestinal injury and paralytic ileus: the gut as both driver and target.\nAbstract: Sepsis-associated acute gastrointestinal injury and paralytic ileus are common but underrecognized manifestations of systemic critical illness and are closely linked to feeding intolerance, barrier failure, secondary infection, and progression to multiorgan dysfunction. However, the gut in sepsis should not be viewed solely as a passive target of distant organ injury. Owing to its unique microbial burden, highly specialized epithelial-immune barrier, and central role in host-microbe and metabolic homeostasis, the gut may function either as an initiator of injury amplification or as a vulnerable downstream target, depending on the infectious source and disease stage. In this review, we propose a source-stratified framework for gut-extraintestinal organ crosstalk in sepsis-associated acute gastrointestinal injury and paralytic ileus. In enterogenic sepsis, the gut more commonly serves as an injury driver through barrier disruption, microbial translocation, dysbiosis, and propagation of inflammatory and metabolic stress signals. In extraintestinal sepsis, the gut more often emerges as a susceptible target of systemic inflammation, microcirculatory failure, neurohumoral dysregulation, and organ-to-organ injury transmission, while subsequent gut dysfunction may in turn amplify remote organ damage. These distinct starting points ultimately converge into a self-reinforcing loop involving epithelial and endothelial barrier failure, immune dysregulation, mitochondrial dysfunction, immunometabolic reprogramming, regulated cell death, extracellular vesicle-mediated signaling, and bidirectional organ injury amplification. We further summarize how these shared mechanisms shape the gut-lung, gut-brain, gut-liver, gut-kidney, and gut-heart axes, and discuss their implications for biomarker development, bedside phenotyping, source-based risk stratification, and mechanism-guided therapeutic strategies. By reframing the gut as both driver and target within a source-dependent network of organ crosstalk, this review aims to provide a more integrative pathobiological model for sepsis-associated gastrointestinal dysfunction and to inform future translational and clinical studies.\n\nID: 41989616\nTitle: Dietary unsaturated fatty acids distinctly associate with the early age sleep-wake cycle and gut integrity in aged fruit flies, Drosophila melanogaster.\nAbstract: Obesity is a risk factor for compromised health and a driver for non-communicable diseases. Effects of various fats on health, behavior, and other parameters have been studied using different model organisms, including fruit flies Drosophila melanogaster, by exposing them to dietary fats (saturated and trans fatty acids). However, the long-term and short-term effects of dietary unsaturated fatty acids (USFA) on physiology and sleep-activity behavior are relatively less explored. Hence, the present study hypothesizes that exposure to a USFA-rich diet differentially influences early-life behavioral traits and long-term fitness in fruit flies. The results of our study reveal that the flies exhibit attraction to USFA, with comparable responses to control and the higher doses. We further observed sexual dimorphism in lifespan, with males fed with low-dose (2.5%) and intermediate-dose (10%) USFA outliving females. Further, upon first-time examining the interaction between behavioral changes and fitness of flies fed with USFA, our results reveal that the females under MUFA increased late-night activity, and the female flies fed highest dose of MUFA (20%) exhibited sleep reorganization, by reduced sleep in nighttime and increased in daytime. Further, MUFA-fed flies enhance sleep fragmentation at an early age. In line at late age, flies fed with an intermediate dose of MUFA showed loose gut integrity (Smurf positive). Overall, this study suggests that USFA-fed flies have shorter survival associated with sleep fragmentation in early life and reduced gut integrity of flies at a late age in a sex and dose-dependent manner. Highlighting sleep fragmentation and gut dysfunction may contribute dietary USFA quality to aging-associated fitness.\n\nID: 41986862\nTitle: Unravelling the Links Between Gastroesophageal Reflux and Lung Disease: New Insights.\nAbstract: Gastroesophageal reflux disease (GERD) is a prevalent comorbidity of chronic respiratory diseases including idiopathic pulmonary fibrosis (IPF), non-IPF interstitial lung disease, asthma, chronic obstructive pulmonary disease (COPD) and refractory chronic cough. Prevalence of symptoms of reflux and/ or refractory respiratory symptoms, along with concerns that refluxed gastric contents into the esophagus may micro-aspirate into the lungs causing injury and potentially accelerate disease progression, have resulted in high usage of empirical anti-reflux treatments. However, empirical treatment of reflux (medical or mechanical) is frequently ineffective without obvious explanation for the lack of respiratory improvement. This review provides novel and updated understanding of the pathophysiological mechanisms that link upper gut dysfunction, reflux (both distal and proximal), lung structure, lung mechanics and breathing patterns, including the potential role of the vagally mediated esophageal-bronchial reflex and the bi-directional nature of these interactions in individual respiratory diseases. We also highlight the need for a consensus between gastrointestinal and respiratory communities and propose a framework for diagnosing and managing GERD in respiratory disease.\n\nID: 41880677\nTitle: Dietary N-acetylneuraminic acid maintains intestinal homeostasis and protects against aging- and inflammation-associated colonic dysfunction.\nAbstract: Intestinal homeostasis is essential for systemic health and longevity, and its disruption contributes to colitis and age-related gut dysfunction. N-acetylneuraminic acid (Neu5Ac), a major form of sialic acid enriched in bird's nest and human milk, exhibits immunomodulatory and antioxidant properties, yet its physiological role in intestinal integrity remains unclear. Here, we demonstrate that oral Neu5Ac supplementation preserves intestinal homeostasis in both natural aging and dextran sulfate sodium (DSS)-induced colitis models. Neu5Ac enhanced epithelial barrier integrity, increased tight-junction proteins, and maintained mucosal architecture. It alleviated systemic and local inflammation by suppressing macrophage infiltration and polarization toward the pro-inflammatory phenotype while maintaining tissue-reparative macrophages. Neu5Ac also selectively enriched butyrate-producing bacterial taxa, including Butyricimonas synergistica and Parabacteroides goldsteinii, thereby increasing fecal butyrate levels, without globally altering microbial diversity. Mechanistically, transcriptomic profiling implicated the HIF-1 signaling pathway in mediating the anti-inflammatory effects of Neu5Ac. Consistently, Neu5Ac reduced colonic HIF-1α protein signals, predominantly localized to inflammatory cells, and suppressed HIF-1α expression in LPS-stimulated macrophages. Neu5Ac promoted epithelial regeneration and mitigated senescence-associated p53 activation, thereby restoring gut homeostasis. Importantly, Neu5Ac exhibited excellent biosafety in vivo. Together, these findings identify Neu5Ac as a bioactive nutritional molecule that sustains intestinal homeostasis through coordinated epithelial, immune, and microbial modulation, offering a promising preventive strategy against aging- and inflammation-driven intestinal disorders.\n\nID: 41872639\nTitle: Early intestinal barrier changes in A53T transgenic Parkinson's disease mice.\nAbstract: Gut dysfunction commonly precedes motor symptoms in Parkinson's disease (PD), but the mechanistic sequence of gut versus brain pathology remains unclear. This work aimed to define the timing of intestinal barrier dysfunction relative to central nervous system (CNS) changes in the A53T α-synuclein transgenic mouse model of PD. Functional and molecular assessments of the gastrointestinal tract (ileum and colon) were conducted at 12 and 36 weeks. We measured in vivo and ex vivo intestinal permeability, nutrient absorption, histomorphology, goblet cell density, and expression of MUC2 and Claudin-1. Inflammatory markers (CRP, TNF-α, CD45) were quantified in plasma and gut tissues. A53T mice exhibited increased intestinal permeability at 12 and 36 weeks, with transiently elevated ex vivo transepithelial electrical resistance (TER) at 12 weeks. Nutrient absorption remained intact. Morphological changes included widened villi and crypts, altered mucin expression, and early reductions in Claudin-1 in the ileum and the colon while inflammatory markers remained largely unchanged. These findings suggest that gut dysfunction precedes known central pathology in A53T mice, supporting further investigation into the gut as an early site of pathology and a potential therapeutic target in PD.\n\nID: 41850537\nTitle: Enteric and Sympathetic Nervous System Pathways Mediate Early Life Stress Effects on Gut Motility and Pain: Mechanistic Findings With Human Correlation.\nAbstract: Adverse experiences during early life can disrupt gut-brain axis development, but the mechanisms linking early life stress (ELS) to long-term gastrointestinal dysmotility and pain remain unclear. We used a maternal separation (MS) mouse model of ELS and assessed visceral pain sensitivity, intestinal motility, and enteric nervous system (ENS) composition. Two large human pediatric population cohorts were also analyzed for associations between ELS and disorders of gut-brain interaction (DGBI) risk. MS in mice led to visceral hypersensitivity, sex-specific motility defects, and altered ENS composition, including increased serotonergic innervation and changes in subtype-specific neuronal proportions. Degarelix-mediated suppression of gonadal hormones reversed MS-induced visceral pain and motility defects, implicating sex hormones in long-term gut changes. MS led to enhanced sympathetic innervation of the ENS and chemical sympathectomy restored normal motility, suggesting sympathetic overactivity in ELS-related gut dysfunction. In humans, significant associations between maternal mental health problems and pediatric DGBI were observed in both cohorts, mirroring preclinical findings. These results identify ELS-driven changes in enteric, sensory, and sympathetic pathways as contributors to DGBI risk and offer insight into potential therapeutic targets.\n\nID: 41837770\nTitle: Magnesium Deficiency Accelerates Gut Aging and Increases Susceptibility to Colitis.\nAbstract: Aging is linked to a higher incidence of gut diseases such as inflammatory bowel disease (IBD), yet the underlying mechanisms remain unclear. We identified an age-related decline in magnesium (Mg) levels specifically in the gut across species, prompting investigation of its role in intestinal health. Functional studies demonstrated that Mg restriction accelerates gut aging in old but not in young mice and aggravates colitis severity. Multi-omics analysis of mouse tissues revealed that dietary Mg deficiency reshapes the phosphoproteome and N-glycoproteome, destabilizing adhesion complexes, a hallmark of intestinal aging and inflammation. In the UK Biobank cohort (n = 182,213), dietary Mg intake was inversely correlated with gut disorder risk, with 334.7-420.0 mg/day conferring significant protection against Crohn's disease, ulcerative colitis, irritable bowel syndrome, and diverticular disease. These findings identify Mg homeostasis as a key regulator of gut health and highlight Mg supplementation as a potential strategy to counteract age-related gut dysfunction.\n\nID: 41834256\nTitle: In Silico and In Vitro Therapeutic Effects of Phycocyanin Against Lipid Micelle and/or Endotoxin-Induced Oxidative Damage and Barrier Dysfunction in Human Intestinal Epithelial Cells Model.\nAbstract: Obesity is associated with chronic intestinal inflammation, oxidative stress, and disruption of epithelial barrier integrity. Phycocyanin (PHY), a bioactive pigment from Spirulina platensis, is known for its antioxidant and anti-inflammatory activities. This study was conducted to evaluate the protective effect of PHY on the disruption of the intestinal epithelium induced by repeated lipid micelles (LM) and/or inflammation induced by lipopolysaccharides (LPS) in the Caco-2 cell line. Firstly, we evaluated the protective actions of PHY against cytotoxicity, oxidative stress imbalance, inflammatory response, and epithelial barrier alteration through an in vitro model, the intestinal Caco-2 cells, treated with LPS and/or LM. We also conducted an in silico molecular docking with PHY. In vitro, PHY was not cytotoxic to Caco-2 cells; instead, it improved cell viability, demonstrated antioxidant and inflammation-suppressing effects, preserved tight junction organization, and protected against endoplasmic reticulum (ER) stress, thereby maintaining epithelial barrier integrity. In silico analysis revealed strong binding affinity of PHY to antioxidant enzymes (SOD, CAT) and favorable interactions with pro-inflammatory cytokines (TNF-α, IL-6), supporting its regulatory potential. Taken together, these findings indicate that PHY protects Caco-2 cells, preserving intestinal barrier integrity under oxidative and inflammatory stress, and may serve as a natural therapeutic candidate against obesity-related gut dysfunction.\n\nID: 41786890\nTitle: The short-chain fatty acid butyrate prevents gut-brain amyloid-β pathology and neuroinflammation in an Alzheimer mouse model.\nAbstract: Amyloid-β (Aβ) plays a critical role in Alzheimer's disease (AD) and its accumulation in the brain is pivotal to disease progression and precedes memory and neuronal loss. Besides the severely handicapping brain symptoms, AD patients display early gastro-intestinal (GI) manifestations such as upper and lower GI dysmotility, in particular constipation. Although there is increasing evidence of Aβ accumulation in the gut, its pathogenic effects on enteric nervous system (ENS) connectivity and gut function as well as underlying pathophysiological mechanisms are poorly understood. Furthermore, studies have reported a gut to brain transmission of Aβ that causes memory deficits in mice. Therefore, identifying therapeutics which can reduce Aβ accumulation in the gut at an early stage of the disease could have the advantage of slowing or even reversing disease progression before severe alterations or irreversible damages at both intestinal and brain levels. Hence, in this study, we investigated the capacity of the short-fatty acid butyrate to restore Aβ-driven alteration of ENS connectivity and gut-brain functions in the SAMP8 mouse model of AD. Here we show that SAMP8 mice display a gut amyloid pathology, an alteration of ENS connectivity and gut defects prior to memory decline. BACE1, an Aβ-producing enzyme, expression and activity are increased whereas neprilysin, an Aβ-degrading enzyme, is decreased in the gut of SAMP8 mice, indicating a rise in the Amyloid Precursor Protein (APP) holoprotein processing and a reduction of Aβ clearance which promote an amyloidosis. In primary ENS cultures, Aβ causes a degradation of synaptic-associated proteins EphB2 and synaptophysin, leading to an alteration of ENS connectivity. In wild-type mice, intra-colon delivery of Aβ alters ENS connectivity and causes subsequent GI symptoms, recapitulating the phenotype of the SAMP8 mouse model of aging and AD. Moreover, Aβ impairs ENS connectivity in human induced pluripotent stem cell (iPSC)-derived intestinal organoids and explant cultures of human colon, indicating that Aβ causes ENS lesions in models of the human gut. Butyrate, a short-chain fatty acid derived from bacterial metabolism, reduces Aβ secretion and preserves enteric neuronal connectivity in vitro and in vivo, and blocks Aβ accumulation in the gut, brain and plasma in SAMP8 mice. In addition, butyrate ameliorates neuroinflammation and prevents gut dysfunction and memory deficit. Collectively, these findings suggest that Aβ promotes gut symptoms through alteration of ENS connectivity and butyrate counteracts these impairments with an amelioration of neuroinflammation and memory function in AD model.\n\nID: 41775000\nTitle: Yeast probiotic protects gut microbiota diversity and metabolic potential against Cryptosporidiosis-induced disruption in goat kids.\nAbstract: Cryptosporidiosis, caused by Cryptosporidium parvum, is a major cause of enteric disease and gut microbiota disruption in neonatal ruminants. It can lead to impaired growth, increased susceptibility to pathogens, and long-term gut dysfunction. In this study, we investigated whether supplementation with a live yeast probiotic (Saccharomyces cerevisiae Sc47) could help preserve gut microbiota resilience and functional homeostasis during an experimental C. parvum oral infection in goat kids. Thirty male French Alpine goat kids were assigned to three groups: uninfected control (healthy), infected, and infected with yeast supplementation. Longitudinal 16S rRNA gene sequencing, network analysis, and functional metagenomic predictions were used to assess microbial diversity, community composition, co-occurrence patterns, and metabolic potential, with a focus on short-chain fatty acid (SCFA) biosynthesis. Infection induced marked dysbiosis, characterised by a substantial reduction in microbial richness and a widespread loss of SCFA-producing commensals and metabolic functions. In contrast, yeast supplementation significantly reduced oocyst excretion by more than 84% throughout the experiment, attenuated pathogen-induced community shifts, and maintained beneficial genera such as Butyricicoccus and members of the Oscillospiraceae family. Furthermore, network analysis revealed that probiotic treatment preserved microbial association structures and reduced community fragmentation. Consistent with these findings, functional profiling showed the retention of pathways involved in carbohydrate metabolism, amino acid biosynthesis, and SCFA production, suggesting enhanced microbiota resilience. These findings demonstrate that S. cerevisiae supplementation can mitigate infection-associated dysbiosis by controlling pathogenic overgrowth while sustaining commensal bacterial stability and functional capacity. This highlights its potential as a microbiota-targeted strategy to support gut health in neonatal ruminants.\n\nID: 41771902\nTitle: Gut ecosystem dysfunction in parkinson's disease: deciphering faecal metabolome-metagenome links for novel diagnostic panels.\nAbstract: Gut ecosystem dysfunction is implicated in Parkinson's disease (PD), but integrative faecal metabolome-metagenome links are undefined. We explored these interactions in Chinese PD patients to develop diagnostic panels. Targeted faecal metabolomics (LC‒MS/MS) was performed on 132 PD and 113 healthy controls (HCs) and shotgun metagenomics was integrated for 39 PD/HC pairs. We identified 33 significantly altered faecal metabolites in PD (FDR-P < 0.05). A novel 12-metabolite panel could distinguish PD from HCs. Multi-omic integration revealed gut ecosystem dysfunction manifests via co-disruptions in microbial genes (e.g., amino acid metabolism genes) and metabolites. Critically, a combinatorial diagnostic panel integrating faecal metabolites and microbial gene markers achieved exceptional PD detection (AUC = 0.961, 95% CI = 0.923-0.998). This study deciphers metabolome-metagenome links driving gut dysfunction in PD, identifying amino acid metabolism as a core perturbed pathway. The novel diagnostic panels provide mechanistic insights and clinical tools for PD precision diagnosis.\n\nID: 41714630\nTitle: Short lifespan under dietary cholesterol depletion is associated with gut dysfunction in Drosophila melanogaster females.\nAbstract: Dietary restriction may extend lifespan by improving late-life gut health. Because micronutrients mediate the effects of macronutrient ratios on longevity, we examined how cholesterol limitation affects gut health in female Drosophila melanogaster. Low-cholesterol diets increased intestinal permeability and reduced lifespan, however, not all flies lost barrier function before dying. This indicates gut dysfunction is either a marker of ageing, or contributes to death, but predominantly during dietary cholesterol limitation.\n\nID: 41707058\nTitle: Coreopsis Tinctoria Nutt. Polyphenols Protect Intestinal Barrier in Depressed Mice by Modulating TLR4/MYD88/NF-κB Pathway.\nAbstract: Depression is a mental disorder strongly associated with gut dysfunction. This study investigated the protective effects of Coreopsis tinctoria Nutt. polyphenolic (CTNP) extract against intestinal barrier damage in a mouse model of depression induced by chronic unpredictable mild stress (CUMS). CTNP alleviated depressive-like behaviors and enhanced intestinal integrity, as evidenced by decreased serum levels of lipopolysaccharide (LPS) and diamine oxidase (DAO), as well as increased expression of tight junction proteins (Occludin, ZO-1, and MUC2). Furthermore, CTNP reduced the production of pro-inflammatory cytokines (IL-1β, TNF-α, and IL-6) in colon tissue, potentially through inhibition of the TLR4/MYD88/NF-κB signaling pathway. These findings elucidate the underlying mechanism of CTNP's protective effects in depression-related intestinal injury and provide both theoretical insights and practical implications for future research.\n\nID: 41654297\nTitle: Gastrointestinal dysfunction in critically ill patients: A prospective observational study of frequency, severity, risk factors, and outcomes.\nAbstract: Gastrointestinal dysfunction (GD) is common in intensive care patients with a wide range of admission diagnoses. Whether GD increases the severity and worsens outcomes from critical illness remains contentious. The aim of this study was to determine the frequency, severity, and risk factors associated with the development of GD in intensive care patients and to correlate these with clinical outcomes. Adult critically ill patients receiving enteral and/or parenteral nutrition with an expected ICU stay ≥72 h were prospectively studied between February 2019 to July 2020. Predefined GI signs and symptoms, ICU interventions, organ scoring, and clinical outcomes were documented from admission to ICU discharge or at 90 days. Data on GD using the Acute Gastrointestinal Injury (AGI) and Gastrointestinal Dysfunction Score (GIDS) scoring systems were collected, and associations between GD and clinical outcomes (ICU length of stay, mechanical ventilation duration, and mortality) were analysed using logistic regression and Poisson mixed-effects models with fixed and random effects, adjusting for age, illness severity, and other covariates. Of 2247 ICU patients screened, a convenience sample of 100 patients were enrolled (75 general ICU, 25 cardiac ICU; 61 % male; median age 53 years [range 41-82]). All patients had at least one GI dysfunction sign/symptom. Gut dysfunction was present in all patients based on the AGI and 79 % by the GIDS. Severe GD occurred in 46 % (AGI) and 25 % (GIDS). A gut-related ICU admission diagnosis was present in 23 % of patients, which increased the odds of severe GD (AGI OR 9.8, 95 % CI 2.66-31.83, p < 0.001; GIDS OR 4.3, 95 % CI 1.4-13.0, p = 0.01). Elevated serum lactate was associated with GD severity (AGI OR 1.30, p = 0.04; GIDS OR 1.32, p = 0.02). Severe GD was associated with longer ICU stays (median 13 vs 10 days, p = 0.02) and mechanical ventilation duration (12 vs 10.5 days, p = 0.05). A 1-Litre fluid balance was associated with an increase in AGI grading of 5.1 % (p = 0.02) and GIDS of 7.9 % (p < 0.001). Aggressive enteral feeding increased AGI odds by 82 % (OR 1.82, p = 0.015). Multiple inotropes were associated with higher GIDS at 72 h (p = 0.023). ICU mortality was 21 %, with no differences by GD. These findings support the importance of consistent GD assessment to guide clinical decision-making in critical care. There is an urgent need for a robust, standardised, and objective approach to GD assessment in ICU practice, one that accounts for severity, dynamic risk factors, and the potential to alter clinical outcomes through timely recognition and intervention.\n\nID: 41565402\nTitle: Human umbilical cord MSC-derived exosomes attenuate radiation-induced pulmonary fibrosis via remodeling the gut-lung axis in mice.\nAbstract: To investigate whether human umbilical cord mesenchymal stem cell-derived exosomes (hUC-MSC-Exos) attenuate radiation-induced pulmonary fibrosis (RIPF) through modulation of the gut-lung axis. The therapeutic efficacy of hUC-MSC-Exos was evaluated in a mouse model of RIPF through histopathology and western blot analysis of fibrosis markers (α-SMA, Vimentin, and E-cadherin). Gut barrier integrity (ZO-1, Occludin) and intestinal inflammation (IL-6, IL-1β) were examined using immunohistochemistry, RT-qPCR, and ELISA. Gut microbial composition and metabolic profiles were characterized via metagenomics and untargeted metabolomics, followed by integrated bioinformatics analyses to identify key pathways and metabolites. hUC-MSC-Exos significantly reduced pulmonary collagen deposition and restored fibrosis markers expression, concomitant with enhanced gut barrier function and attenuated intestinal inflammation. Multi-omics analysis revealed restoration of gut microbiota homeostasis and metabolic reprogramming, with the alanine, aspartate, and glutamate pathway being notably co-regulated. L-Glutamic acid was the most significantly altered metabolite and correlated significantly positively with the severity of pulmonary fibrosis and gut dysfunction. Gut microbiota associated with L-Glutamic acid (e.g., Duncaniella, Ruminococcus) were also significantly restructured. hUC-MSC-Exos attenuate RIPF through a comprehensive remodeling of the gut-lung axis, in which L-Glutamic acid and its associated microbiota serve as potential mediators. These findings highlight the gut-lung axis as a promising therapeutic target for RIPF.\n\nID: 41554750\nTitle: C1q-dependent clearance of alpha-synuclein allows macrophages to transiently limit enteric synucleinopathy in male mice.\nAbstract: Deposition of misfolded α-synuclein (αsyn) in the enteric nervous system (ENS) is found in multiple neurodegenerative diseases. It is hypothesized that ENS synucleinopathy contributes to both the pathogenesis and non-motor morbidity in Parkinson's Disease (PD), but the cellular and molecular mechanisms that shape enteric histopathology and dysfunction are poorly understood. Here, we employ a fibrillar injection model of enteric synucleinopathy in male mice and demonstrate that ENS-resident macrophages, which play a critical role in maintaining ENS homeostasis, initially respond to enteric neuronal αsyn pathology by upregulating machinery for complement-mediated engulfment. Pharmacologic depletion of ENS-macrophages or genetic deletion of C1q enhanced enteric neuropathology. Conversely, C1q deletion ameliorated gut dysfunction, indicating that complement partially mediates αsyn-induced gut dysfunction. However, this C1q-dependent clearance mechanism diminished over time and its failure temporally correlated with the further increase in ENS pathology. These findings highlight the importance of enteric neuron-macrophage interactions in removing toxic protein aggregates that putatively shape the gastrointestinal manifestations of PD.\n\nID: 41543761\nTitle: Towards treatments targeting the gut to improve behavioural outcomes in autism spectrum disorder.\nAbstract: Autism spectrum disorder (ASD; autism) is a prevalent and heterogeneous neurodevelopmental disorder characterised by social communication difficulties, repetitive behaviour, and restricted interests. For individuals with autism, in particular those who require substantial care-giver support, irritability, heightened sensitivity and aggressive behaviours in response to sensory, social, or environmental triggers can limit access to health, education and community services and impact quality of life. Although gastrointestinal (GI) symptom severity is associated with irritable behaviours in autism, there are few approved medications to address challenging behaviour or comorbid psychiatric disorders, or gut dysfunction in autism. Here, we review the mode of action of drugs undergoing clinical trials for treating irritable behaviour and improving social communication as well as potentially gastrointestinal symptoms in individuals with autism. Repurposed medications such as pimavanserin (an atypical antipsychotic) and the antiparasitic suramin are being trialled for treating irritable behaviours and impaired social interaction, respectively, in autism. NTI164 is a medicinal cannabis-derived biopharmaceutical undergoing clinical safety and efficacy trials for improving social communication and similarly, ML-004 is an investigational drug being assessed for treating social communication deficits. Two other repurposed medications previously utilised for schizophrenia; brexpiprazole and lumateperone, as well as AB-2004, a microbial metabolite sequestering agent (with proposed actions on gut function), are undergoing clinical trials to assess impacts on irritability associated with autism. We also outline emerging findings from clinical studies on the use of gut-targeted small molecules and bacteriophage therapy, prebiotics, probiotic supplementation and faecal microbiota transplantation (FMT), and their potential impact on behavioural symptoms in autism.\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’s complementary-but-disjoint (A-B-C) model.

In this study, 69 lactic acid bacteria (LAB) were isolated from Yucha and shrimp paste in Hainan, China. Four strains, Lactiplantibacillus plantarum Lpl-YC37, Lacticaseibacillus paracasei Lpa-XJ120, and Pediococcus pentosaceus Ppe-YC39 and Ppe-XJ37 were selected as starters based on probiotic property and safety evaluation. Inoculation with these LAB starters significantly enriched beneficial metabolites, with Ppe-XJ37 showing a four-fold increase in acetic acid, the dominant short-chain fatty acids. Additionally, all LAB inoculation enhanced free amino acids, particularly L-glycine, improving flavor and nutritional value. Crucially, LAB inoculation drastically suppressed biogenic amines, reducing putrescine from 55.23 μg g-1 in the control to 5.77 μg g-1 in the Lpl-YC37 group, highlighting improved safety. These findings demonstrate that tropical fermented foods harbor indigenous LAB starters, providing a scalable approach to modernize these foods for improved quality and safety.\n  --- END ACTUAL ABSTRACT FOR 41795531 ---\n\n\n✅ PASSED (DO NOT CHANGE THESE):\n- \"Tyramine supplementation promoted MASLD-related metabolic phenotype in mice.\" (Source: 41299593)\n- \"Tyramine contributed to lipid accumulation mainly by increasing lipid synthesis and lipid uptake but reducing the β-oxidation processes in the mouse liver\" (Source: 41299593)\n- \"This favorable microbial shift was accompanied by a reconfiguration of the intestinal metabolome, characterized by elevated production of beneficial short-chain fatty acids (SCFAs) and decreased levels of pro-inflammatory metabolites such as tyramine.\" (Source: 42083198)\n- \"The results showed that combined histamine and tyramine administration increased cleaved PARP-1 and IL-1β in the liver, as well as MAO-A, total MAO, CRP, and AST/ALT levels.\" (Source: 36899958)\n- \"Treatment with manufactured or traditional fermented soybean paste decreased biogenically elevated hepatic cleaved PARP-1 and IL-1β expression and blood plasma MAO-A, CRP, and AST/ALT levels in HFD-induced NAFLD mice.\" (Source: 36899958)\n- \"Crucially, LAB inoculation drastically suppressed biogenic amines, reducing putrescine from 55.23 μg g-1 in the control to 5.77 μg g-1 in the Lpl-YC37 group, highlighting improved safety.\" (Source: 41795531)\n- \"In the ileum, as compared with FOS, CP increased the bacteria with high capability of fermenting amino acids, including Escherichia-Shigella and Klebsiella (adjusted P < 0.05), and the expression of enzymes responsible for amino acid fermentation (i.e. lysine decarboxylase), as well as the amino acid fermentation products (cadaverine and tyramine) (P < 0.05)\" (Source: 36263407)\n- \"metabolomic analysis showed that differential metabolites were enriched in the neuroactive ligand-receptor interaction pathway, in which GABA (γ-aminobutyric acid), histamine and tyramine metabolites were positively correlated with the above species and police performance.\" (Source: 41840712)\n- \"The results showed that Pulsatilla chinensis powder significantly increased gamma-glutamylcysteine (p < 0.05), UDP-N-acetylglucosamine (p < 0.05), tyramine (p < 0.01), and leucine (p < 0.05).\" (Source: 40362077)\n- \"Acetate, 4-hydroxyphenyl, galactose, proline, and tyramine were identified as key fecal metabolites for prediction purposes.\" (Source: 42042907)\n- \"Our study identified elevated fecal trace amine levels in ulcerative colitis (UC) patients and DSS-induced colitis mice.\" (Source: 41550498)\n- \"Among the identified biogenic amines, tyramine and histamine were most frequently reported at high concentrations.\" (Source: 41494586)\n- \"Additionally, the accumulation of biogenic amines was inhibited to ensure the palatability of the feed.\" (Source: 41286532)\n- \"In vitro experiments showed that Ped. pentosaceus L1 presented high cell surface hydrophobicity, strong antioxidant activity, no hemolytic activity, and did not synthesize biogenic amines including cadaverine, putrescine, or agmatine.\" (Source: 41191059)\n- \"the results demonstrated that both strains exhibited good survival rates under in vitro simulated stomach duodenum-passage.

Dietary strategies to mitigate these risks focus on the selection of specific probiotic starters and functional foods that either inhibit biogenic amine production or facilitate their metabolic reduction, thereby preserving intestinal barrier integrity and reducing systemic pro-inflammatory signaling.\n\n### [INTRODUCTION & JUSTIFICATION]\nExcessive tyramine, a biogenic amine produced through amino acid decarboxylation by specific gut microbiota, is increasingly recognized as a deleterious factor in metabolic and intestinal diseases. Clinical and preclinical data reveal that tyramine-producing bacteria—such as *Enterococcus faecium*—can disrupt intestinal barriers and promote hepatic lipid accumulation. Conversely, mitigating tyramine levels through the introduction of specific probiotic strains (e.g., *Lactobacillus* and *Pediococcus* species) or fermentable fiber interventions offers a therapeutic path to improve outcomes in NAFLD and colitis. By modulating the gut-liver axis through the enrichment of beneficial bacteria, these interventions suppress the decarboxylase activities that generate tyramine, thereby restoring intestinal homeostasis and reducing the inflammatory burden on the liver.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Specific probiotic combinations, such as *Lactobacillus acidophilus* and *Lactiplantibacillus plantarum*, can achieve up to an 80% reduction in total biogenic amine levels during food fermentation.\n*   The gut microbiota can be reconfigured by prebiotic interventions (e.g., squid-derived chondroitin sulfate) to shift the metabolome toward beneficial short-chain fatty acids (SCFAs) and away from harmful metabolites like tyramine.\n*   Fermented soybean paste (Doenjang) has been shown to reduce biogenic amine-induced liver damage and improve survival rates in obese mouse models of NAFLD.\n*   The presence of tyramine in the gut is not exclusively endogenous; certain dietary inputs can directly increase amine levels if the microbiota environment favors amino acid fermentation over carbohydrate fermentation.\n*   Inhibitors of trace amine signaling, such as the TAAR1 antagonist EPPTB, show potential in alleviating colitis symptoms by suppressing the downstream effects of elevated gut trace amines.\n*   Metabolic profiling of gut ecosystems in diseased populations reveals that tyramine production is often linked to the down-regulation of beneficial metabolic pathways, such as riboflavin metabolism in pediatric non-organic anorexia.\n*   Microbiome-host interactions indicate that even in the absence of exogenous dietary tyramine, high-fat diets can promote the proliferation of tyramine-producing bacteria, worsening liver fibrosis and inflammation.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Opiate agonists and endogenous opioid peptides inhibit electrolyte secretion both in vitro and in vivo. These drugs appear to act at several levels. Thus, opioid effects can be elicited at the local mucosal level. Secondly, antisecretory effects can be demonstrated when opioids are administered into the brain. These central effects appear to involve activation of the sympathetic innervation of the intestine. Thirdly, some antidiarrhoeal drugs such as loperamide may have ancillary non-opiate-like actions that contribute to their effectiveness. In cases of inflammatory bowel disease where local concentrations of inflammatory mediators such as kinins and eicosanoids may be high, non-steroidal anti-inflammatory drugs may be effective in treating diarrhoeal symptoms. The existence of many types of receptors on mucosal cells indicates that several pharmacological approaches exist for the potential modulation of electrolyte transport.","3283291":"ID: 3283291\nTitle: Antidepressant drug therapy: associated risks.\nAbstract: Aspects of risks associated with treatment with three classes of antidepressants: tricyclic (TCA), second generation (\"new\") antidepressants and monoamine oxidase inhibitor (MAOI), are discussed. Moclobemide, a benzamide derivative, is a new MAOI antidepressant with reversible and preferential inhibition of the A-form of monoamine oxidase. Moclobemide is free of liver toxicity and the risk of a pressor response with tyramine-containing food is so low that strict diet restrictions are unnecessary. That MAOIs have a low incidence of side effects, particularly so called anticholinergic side effects is also true for moclobemide. A serious risk with antidepressant drugs is that the patient will use them to attempt suicide. Therefore important aspects of antidepressants are that they should take effect rapidly and be safe in overdose. No deaths from overdose have been observed with toloxatone, the only reversible MAOI antidepressant on the market to date. It is concluded that the new reversible MAOI antidepressant moclobemide is similar to other antidepressants in terms of efficacy but very noticeably superior in terms of tolerance and safety.","6744787":"ID: 6744787\nTitle: Bile salts, hypotension and obstructive jaundice.\nAbstract: We have examined the effects of bile duct ligation on vascular and extravascular smooth muscle responsiveness to noradrenaline and tyramine using isolated rat hindlimb perfusion, and portal vein and vas deferens preparations. Bile duct ligation reduced the contractile responses to noradrenaline of vascular and extravascular smooth muscle. Exposure of smooth muscle to some bile salts caused a reduction in contractility. This effect was dependent upon bile salt type and concentration. These studies in vitro suggest that the reduced total peripheral resistance and hypotension seen in obstructive jaundice cannot be explained by a spasmolytic effect of some of the bile salts on smooth muscle.","7458927":"ID: 7458927\nTitle: Depressed uptake of serotonin by platelets in hepatic encephalopathy.\nAbstract: ","9660426":"ID: 9660426\nTitle: Relation of endometriosis and neuromuscular disease of the gastrointestinal tract: new insights.\nAbstract: To investigate the neuromuscular activity of the gastrointestinal tract by antroduodenal manometry in women with endometriosis documented by laparoscopy, to assess the effects of diet and drug therapy on symptoms, and to assess the bacterial overgrowth that is commonly associated with these nerve diseases. Prospective, open-label study. A clinical center for the care of women's health. Fifty women with endometriosis documented by laparoscopy and gastrointestinal tract symptoms characterized by chronic abdominal pain, nausea, vomiting, early satiety, bloating and distention, and altered bowel habits. Motility of the gastrointestinal tract was recorded and bacterial overgrowth was assessed. Treatment consisted of dietary changes, including reduction of glycemic carbohydrates, balancing with omega 9 oils, elimination of foods with caffeine and tyramine, and addition of omega 3 fatty acids, as well as drug therapy with clonazepam (0.25 mg 3 times per day). All 50 women showed a characteristic motility change (ampulla of Vater-duodenal wall spasm, a seizure equivalent of the enteric nervous system). Forty of the women showed bacterial overgrowth. There was a significant reduction in the total symptom score after 8 weeks of treatment. This study suggests that endometriosis and gastrointestinal tract symptoms are a result of the dysfunction of hollow organs. Correction of the biochemical imbalance of the eicosanoid system and the hypersecretion of insulin that results from excessive intake of glycemic carbohydrates and lack of essential fatty acids significantly decreases symptoms in patients with endometriosis and associated neuromuscular disease of the gastrointestinal tract.","22061231":"ID: 22061231\nTitle: Contaminant lactic acid bacteria of dry sausages produce histamine and tyramine.\nAbstract: Exogenous biogenic amines present a food poisoning hazard in fermented foods especially with additional risk factors, e.g. amine oxidase inhibiting drugs, alcohol and gastrointestinal diseases. Forty-two lactic acid bacteria (LAB) strains were isolated from seven dry sausages during ripening (0 day, 21 day and 49 day). Their ability to produce histamine and tyramine was studied by HPLC detection from broth cultures after 2 days incubation. The tyramine and histamine concentrations in sausages increased during fermentation. 10 of 42 LAB strains produced 402-1087 ppm tyramine. Four of these 10 contaminant LABs were also histamine-positive (725-1083 ppm). Most of the amine positive strains were found in sausages at the end of ripening and with highest amine levels. On the basis of these results the contaminant LABs play an important role in tyramine and histamine formation during the ripening of dry sausages. Therefore it could be possible to decrease the levels of amines formed by limiting the initial level and growth of these contaminant bacteria.","23328125":"ID: 23328125\nTitle: Injectable hyaluronic acid-tyramine hydrogels incorporating interferon-α2a for liver cancer therapy.\nAbstract: We report an injectable hydrogel system that incorporates interferon-α2a (IFN-α2a) for liver cancer therapy. IFN-α2a was incorporated in hydrogels composed of hyaluronic acid-tyramine (HA-Tyr) conjugates through the oxidative coupling of Tyr moieties with hydrogen peroxide (H2O2) and horseradish peroxidase (HRP). IFN-α2a-incorporated HA-Tyr hydrogels of varying stiffness were formed by changing the H2O2 concentration. The incorporation of IFN-α2a did not affect the rheological properties of the hydrogels. The activity of IFN-α2a was furthermore well-maintained in the hydrogels with lower stiffness. Through the caspase-3/7 pathway in vitro, IFN-α2a released from HA-Tyr hydrogels inhibited the proliferation of liver cancer cells and induced apoptosis. In the study of the pharmacokinetics, a higher concentration of IFN-α2a was shown in the plasma of mice treated with IFN-α2a-incorporated hydrogels after 4h post injection, with a much higher amount of IFN-α2a delivered at the tumor tissue comparing to that of injecting an IFN-α2a solution. The tumor regression study revealed that IFN-α2a-incorporated HA-Tyr hydrogels effectively inhibited tumor growth, while the injection of an IFN-α2a solution did not demonstrate antitumor efficacy. Histological studies confirmed that tumor tissues in mice treated with IFN-α2a-incorporated HA-Tyr hydrogels showed lower cell density, with more apoptotic and less proliferating cells compared with tissues treated with an IFN-α2a solution. In addition, the IFN-α2a-incorporated hydrogel treatment greatly inhibited the angiogenesis of tumor tissues.","26239676":"ID: 26239676\nTitle: N‑trans‑ρ‑caffeoyl tyramine isolated from Tribulus terrestris exerts anti‑inflammatory effects in lipopolysaccharide‑stimulated RAW 264.7 cells.\nAbstract: Inflammation is induced by the expression of cyclooxygenase‑2 (COX‑2), which is an important mediator of chronic inflammatory diseases, such as rheumatoid arthritis, asthma and inflammatory bowel disease. Tribulus terrestris (T. terrestris) is known to have a beneficial effect on inflammatory diseases. In this study, we investigated the effects of N‑trans‑ρ‑caffeoyl tyramine (CT) isolated from T. terrestris on the production of nitric oxide (NO), and the expression of pro‑inflammatory cytokines and COX‑2 in lipopolysaccharide (LPS)‑stimulated RAW 264.7 cells. We also aimed to elucidate the molecular mechanisms involved. We found that the ethanolic extract of T. terrestris (EETT) and CT inhibited the production of NO, tumor necrosis factor‑α (TNF‑α), interleukin (IL)‑6 and IL‑10 in the LPS‑stimulated RAW 264.7 cells in a dose‑dependent manner. They were determined by reverse transcription-polymerase chain reaction (RT-PCR) and enzyme-linked immunosorbent assay (ELISA). In addition, CT markedly suppressed the expression of COX‑2 and the production of prostaglandin E2 (PGE2) in response to LPS stimulation. Furthermore, CT markedly decreased p‑c‑Jun N‑terminal kinase (p‑JNK) protein expression in LPS‑stimulated RAW 264.7 cells. COX-2 and p-JNK were measured by western blot analysis. Taken together, these findings indicate that CT isolated from T. terrestris is a novel and potent modulator of inflammatory responses. Thus, it may prove benefiical to further evaluate CT as a possible treatment for chronic inflammatory diseases.","30013475":"ID: 30013475\nTitle: Trace Amine-Associated Receptors as Novel Therapeutic Targets for Immunomodulatory Disorders.\nAbstract: Trace amines and their receptors (trace amine-associated receptors; TAARs) are an emerging pharmacological target for the treatment of human disorders.

Furthermore, recent independent, unbiased metabolomic studies have consistently identified one or more TAAR ligands as potential etiologic factors in inflammatory bowel disease (IBD). The putative role of TAARs in diseases such as IBD that are associated with hyperactive immune responses has not, however, previously been systematically addressed. Here, we review the current state of the knowledge of the effects of TAARs on leukocyte function, in particular in the context of mucosal epithelial cells that interface with the environment; developing a model whereby TAARs may be considered as a novel therapeutic target for disorders associated with dysregulated immune responses to environmental factors. In this model, we hypothesize that altered trace amine homeostasis results in hyperactivity of the immune system. Such loss of homeostasis can occur through many different mechanisms including TAAR polymorphisms and altered trace amine load due to changes in host synthesis and/or degradative enzymes, diet, or microbial dysbiosis. The resulting alterations in TAAR functioning can then lead to a loss of homeostasis of leukocyte chemotaxis, differentiation, and activation, as well as an altered ability of members of the microbiota to adhere to and penetrate the epithelial cell layers. Such changes would generate a pro-inflammatory state at mucosal epithelial barrier layers that can manifest as clinical symptomatology such as that seen in IBD. These alterations may also have the potential to induce systemic effects, which could possibly contribute to immunomodulatory disorders in other systems, including neurological diseases.","30841454":"ID: 30841454\nTitle: Effect of N-methyltyramine on the regulation of adrenergic receptors via enzymatic epinephrine synthesis for the treatment of gastrointestinal disorders.\nAbstract: Citri Reticulatae Pericarpium (CRP), Aurantii Fructus Immaturus (AFI) and Aurantii Fructus (AF) are all important Citrus species used in traditional Chinese medicines (TCMs) for the treatment of gastrointestinal disorders. Although they have been used since ancient times and are still in use today, the mechanistic basis for their regulation of adrenergic receptors (ARs) is still not clear. In this study, we aimed to determine the active components and mechanisms of action of CRP, AFI and AF in treating gastrointestinal disorders related to ARs. First, the phenethylamine alkaloid components of CRP, AFI and AF were identified and compared across 30 samples of three Citrus species by UPLC-Q/TOF-MS in combination with content difference analysis. Second, the effect of the main active alkaloid component on AR-based gastrointestinal disorders was investigated by an in vivo small intestinal propulsive test and an in vitro relaxing small intestinal smooth muscle activity test. The mechanism of AR regulation of the active alkaloid was further studied by evaluating its effect on relaxing small intestinal smooth muscle in the presence of an inhibitor. Lastly, the enzymes, which played an important role in epinephrine synthesis and AR regulation, were detected by immunohistochemistry. Three phenethylamine AR regulators (N-methyltyramine, synephrine and hordenine) in CRP, AFI and AF were characterized. It was found that N-methyltyramine could relax mouse small intestinal smooth muscle and inhibit small intestinal propulsion. The effect of N-methyltyramine on relaxing small intestinal smooth muscle could be inhibited by a-methyl-l-tyrosine. The enzymes related epinephrine synthesis and AR function were found in the mouse small intestine. The biotransformation process that converts N-methyltyramine to epinephrine was determined. The treatment of gastrointestinal disorders of CRP, AFI and AF is associated with their alkaloid component N-methyltyramine via the regulation of ARs, and the mechanism is considered to be the biotransformation of N-methyltyramine to epinephrine by serial synthase, which takes place at the nerves cells in small intestine.","32628331":"ID: 32628331\nTitle: Dietary supplementation with Bacillus subtilis DSM 32315 alters the intestinal microbiota and metabolites in weaned piglets.\nAbstract: The study was conducted to investigate the effects of dietary Bacillus subtilis (BS) DSM 32315 on the intestinal microbiota composition and metabolites of weaned pigs. Sixty-four piglets were allocated to two groups (control and BS), each group including eight replicates with four piglets. Dietary BS DSM 32315 increased (P < 0·05) the abundances of jejunal Leucobacter and Cupriavidus, ileal Thermus, Coprococcus and Bifidobacterium, as well as colonic Succiniclasticum; and increased the concentrations of ileal straight-chain fatty acids, colonic propionate, branched-chain fatty acids (BCFAs), and tyramine, but decreased (P < .05) the colonic indole concentration. The ileal and colonic microbial community structure tended to cluster into two groups. LEfSe analysis identified five microbial biomarkers in jejunum and eight biomarkers in ileum in the BS group, and three biomarkers in colon in the control group. The ileal Bifidobacterium abundance was positively correlated (P < 0·05) with isovalerate concentration, while the colonic Actinobacteria and Lactobacillus abundances were negatively correlated (P < 0·05) with indole concentration. These findings suggest that dietary supplementation with BS DSM 32315 could alter the diversity, composition, and metabolites of intestinal microbiota in weaned piglets. Weaned piglets are often accompanied with impaired gastrointestinal tract and intestinal disorder affecting their growth. This study demonstrated that dietary BS DSM 32315 presented a beneficial role in gut health via regulating intestinal microbiota composition and metabolites.","33289566":"ID: 33289566\nTitle: Gut Microbiota-Derived Metabolite Signature in Suckling and Weaned Piglets.\nAbstract: The gut microbiota plays a key role in intestinal development at the suckling-to-weaning transition. The objective of this study was to analyze the production of metabolites by the gut microbiota in suckling and weaned piglets. We studied piglets raised in two separate maternity farms and weaned at postnatal day 21 in the same farm. The fecal metabolome (1H nuclear magnetic resonance) and the microbiota composition (16S rRNA gene amplicon sequencing) and its predicted functions (PICRUSt2) were analyzed in the same piglets during the suckling period (postnatal day 13) and 2 days after weaning (postnatal day 23). The relative concentrations of the bacterial metabolites methylamine, dimethylamine, cadaverine, tyramine, putrescine, 5-aminovalerate, succinate, and 3-(4-hydroxyphenylpropionate) were higher during the suckling period than after weaning. In contrast, the relative concentrations of the short-chain fatty acids acetate and propionate were higher after weaning than during the suckling period. The maternity of origin of piglets also influenced the level of some bacterial metabolites (propionate and isobutyrate). The fecal metabolome signatures observed in suckling and weaned piglets were associated with specific microbiota-predicted functionalities, structure, and diversity. Gut microbiota-derived metabolites, which are differentially abundant between suckling and weaned piglets (e.g., short-chain fatty acids and biogenic amines), are known to regulate gut health. Thus, identification of metabolome signatures in suckling and weaned piglets paves the way for the development of health-promoting nutritional strategies, targeting the production of bacterial metabolites in early life.","33846627":"ID: 33846627\nTitle: Gut-inhabiting Clostridia build human GPCR ligands by conjugating neurotransmitters with diet- and human-derived fatty acids.\nAbstract: Human physiology is regulated by endogenous signalling compounds, including fatty acid amides (FAAs), chemical mimics of which are made by bacteria. The molecules produced by human-associated microbes are difficult to identify because they may only be made in a local niche or they require a substrate sourced from the host, diet or other microbes. We identified a set of uncharacterized gene clusters in metagenomics data from the human gut microbiome. These clusters were discovered to make FAAs by fusing exogenous fatty acids with amines. Using an in vitro assay, we tested their ability to incorporate 25 fatty acids and 53 amines known to be present in the human gut, from which the production of six FAAs was deduced (oleoyl dopamine, oleoyl tyramine, lauroyl tryptamine, oleoyl aminovaleric acid, α-linolenoyl phenylethylamine and caproyl tryptamine). These molecules were screened against panels of human G-protein-coupled receptors to deduce their putative human targets. Lauroyl tryptamine is found to be an antagonist to the immunomodulatory receptor EBI2 against its native oxysterol ligand (0.98 μM half-maximal inhibitory concentration), is produced in culture by Eubacterium rectale and is present in human faecal samples. FAAs produced by Clostridia may serve as a mechanism to modulate their host by mimicking human signalling molecules.","33976215":"ID: 33976215\nTitle: Gut microbiome modulates Drosophila aggression through octopamine signaling.\nAbstract: Gut microbiome profoundly affects many aspects of host physiology and behaviors. Here we report that gut microbiome modulates aggressive behaviors in Drosophila. We found that germ-free males showed substantial decrease in inter-male aggression, which could be rescued by microbial re-colonization. These germ-free males are not as competitive as wild-type males for mating with females, although they displayed regular levels of locomotor and courtship behaviors. We further found that Drosophila microbiome interacted with diet during a critical developmental period for the proper expression of octopamine and manifestation of aggression in adult males. These findings provide insights into how gut microbiome modulates specific host behaviors through interaction with diet during development.","34799768":"ID: 34799768\nTitle: Duodenal Microbiome and Serum Metabolites Predict Hepatocellular Carcinoma in a Multicenter Cohort of Patients with Cirrhosis.\nAbstract: Hepatocellular carcinoma (HCC) is rapidly increasing in the U.S. and is a leading cause of mortality for patients with cirrhosis. Discovering novel biomarkers for risk stratification of HCC is paramount. We examined biomarkers of the gut-liver axis in a prospective multicenter cohort. Patients with cirrhosis without a history of HCC were recruited between May 2015 and March 2020 and prospectively followed at 3 tertiary care hospitals in Los Angeles. Microbiome analysis was performed on duodenal biopsies and metabolomic analysis was performed on serum samples, collected at the time of enrollment. Optimal microbiome-based survival analysis and Cox proportional hazards regression analysis were used to determine microbiota and metabolite associations with HCC development, respectively. A total of 227 participants with liver cirrhosis contributed a total of 459.58 person-years of follow-up, with 14 incident HCC diagnoses. Male sex (HR = 7.06, 95% CI = 1.02-54.86) and baseline hepatic encephalopathy (HE, HR = 4.65, 95% CI = 1.60-13.52) were associated with developing HCC over follow-up. Adjusting for age, sex, baseline HE, and alkaline phosphatase, an increased risk of HCC were observed for participants with the highest versus lowest three quartiles for duodenal Alloprevotella (HR = 3.22, 95% CI = 1.06-9.73) and serum taurocholic acid (HR = 6.87, 95% CI = 2.32-20.27), methionine (HR = 9.97, 95% CI = 3.02-32.94), and methioninesulfoxide (HR = 5.60, 95% CI = 1.84-17.10). Being in the highest quartile for Alloprevotella or methionine had a sensitivity and specificity for developing HCC of 85.71% and 60.56%, respectively, with an odds ratio of 10.92 (95% CI = 2.23-53.48). Alloprevotella and methionine, methioninesulfoxide, and taurocholic acid predicted future HCC development in a high-risk population of participants with liver cirrhosis.","35694542":"ID: 35694542\nTitle: The Microbiota and It's Correlation With Metabolites in the Gut of Mice With Nonalcoholic Fatty Liver Disease.\nAbstract: In recent years, nonalcoholic fatty liver disease (NAFLD) has become the most common liver disease in the world. As an important model animal, the characteristics of gut microbiota alteration in mice with NAFLD have been studied but the changes in metabolite abundance in NAFLD mice and how the gut microbiota affects these intestinal metabolites remain unclear. In this experiment, a mouse model for NAFLD was established by a high-fat diet. The use of 16S rDNA technology showed that while there were no significant changes in the alpha diversity in the cecum of NAFLD mice, the beta diversity changed significantly. The abundance of Blautia, Unidentified-Lachnospiraceae, Romboutsia, Faecalibaculum, and Ileibacterium increased significantly in NAFLD mice, while Allobaculum and Enterorhabdus decreased significantly. Amino acids, lipids, bile acids and nucleotide metabolites were among the 167 significantly different metabolites selected. The metabolic pathways of amino acids, SFAs, and bile acids were significantly enhanced, while the metabolic pathways of PUFAs, vitamins, and nucleotides were significantly inhibited. Through correlation and MIMOSA2 analysis, it is suggested that gut microbiota does not affect the changes of lipids and bile acids but can reduce thiamine, pyridoxine, and promote L-phenylalanine and tyramine production. The findings of this study will help us to better understand the relationship between gut microbiota and metabolites in NAFLD.","35850312":"ID: 35850312\nTitle: Rooibos (Aspalathus linearis) alters secretome trace amine profile of probiotic and commensal microbes in vitro.\nAbstract: Aspalathus linearis (Burm.f.) R. Dahlgren (rooibos) tea is anecdotally renowned for its calming effect in the context of gastrointestinal discomfort, but little scientific support is available to elucidate potential mechanisms of action. Enhancement of dietary polyphenol content to improve gut health via prebiotic-like modulation of the gut microbiota has gained significant research interest. Given the known high polyphenol content of rooibos, rooibos tea may potentially exert a prebiotic effect in the gut to facilitate an improvement in chronic inflammatory gastrointestinal conditions. This study aimed to determine the prebiotic or health-modulating potential of rooibos tea in terms of its effect on gut microbial growth and secretome trace amine composition, as well as to determine how differential rooibos processing alters this activity. Three rooibos preparations (green and fermented leave aqueous extracts, as well as a green leaf ethanol extract) were compared in terms of their phenolic composition (qTOF-LC/MS). Moreover, the effect of rooibos exposure on growth and secretome trace amine levels of probiotic and commensal microbes were assessed (LC/MS). In addition, given the known female bias prevalent for many gastrointestinal disorders, experiments were conducted in the absence and presence of estradiol. Polyphenolic composition of rooibos was drastically reduced by fermentation. Aqueous extracts of both green and fermented rooibos improved microbial growth, although fermented rooibos had the most pronounced effect (p < 0.01). In terms of secretome trace amine profile, both aqueous extracts of rooibos seemed to facilitate increased putrescine secretion (p < 0.0001) and decreased tryptamine production (p < 0.0001). Estradiol seemed to suppress trace amine secretion by bacteria (Lactobacillus plantarum, Lactobacillus reuteri and Enterococcus mundtii) but increased it in yeast (Saccharomyces boulardii). Rooibos altered gut probiotic and commensal microbial growth and secretome trace amine profiles in vitro, suggesting it has potential to modulate gut microbial composition and functionality as a prebiotic. Current data suggest that these effects are highly dependent on raw material processing. Finally, rooibos may be able to prevent estradiol-associated alterations in trace amine profile, which may have important implications for patient management in female-predominant gastrointestinal disorders.","35983599":"ID: 35983599\nTitle: The comparison of the main dietary and non-dietary trigger factors in women with chronic and episodic migraine.\nAbstract: Migraine is one of the most common neurological diseases and the second cause of disability worldwide. Various trigger factors have been reported in different populations. The current study was designed to extract the main trigger factors using factor analysis, and compare the chronic and episodic patient scores for every extracted pattern. In this cross-sectional study, 300 migrainous women (25-55 years old) participated. A constructed 46-item Likert questionnaire was developed to assess the primary triggers. The validity of the designed questionnaire was assessed by Content Validity Ratio and Content Validity Index coefficients. The test-retest method was employed to assess reliability. The exploratory factor analysis was performed to extract patterns of correlation among 46 triggers. Each participant was given a score for every extracted pattern. The mean scores of chronic and episodic patients were compared using the Mann-Whitney test. The mean body mass index of participants was 28.17 ± 5.44 kg/m2 . Most participants (90.7%) had migraine without aura. Four factors were extracted using factor analysis that explained 22.37% of the total variance: (1) environmental and behavioural factors; (2) condiments; (3) nitrite, tyramine and caffeine; and (4) fats. None of these factors explained the difference between chronic and episodic migrainous women. The current study suggests that environmental and behavioural factors, relative to dietary triggers, play an essential role in causing migraine in women and more than dietary triggers. The most important triggers did not differ between episodic and chronic migrainous women.","36178065":"ID: 36178065\nTitle: Effects of low protein diet with a balanced amino acid pattern on growth performance, meat quality and cecal microflora of finishing pigs.\nAbstract: The present study aimed to investigate the effects of low protein diets balanced with four amino acids on growth performance, meat quality and cecal microflora of finishing pigs. Fifty-four healthy hybrid barrows (Duroc × Landrace × Yorkshire) with an average body weight of 70.12 ± 4.03 kg were randomly assigned to one of the three dietary treatments with six replicate pens per treatment (three barrows per pen). The three dietary treatments included a normal protein diet (NP), a low protein diet (LP) and a very low protein diet (VLP). The average daily gain, average daily feed intake and feed conversion ratio of pigs were not significantly changed with the LP and VLP diets compared to the NP diet (P > 0.05). The water holding capacity and shear force of longissimus dorsi muscle were decreased, whereas the intramuscular fat content of the longissimus dorsi muscle was increased (P < 0.05) in pigs fed with the LP and VLP diets compared to the NP diet. The contents of saturated fatty acids in muscle were decreased (P < 0.05), whereas the content of polyunsaturated fatty acids in muscle was increased (P < 0.01) with the VLP diet compared to the NP diet. The contents of histamine, spermidine, spermine and tyramine of muscle were decreased with the VLP diet compared to the NP diet (P < 0.05). The relative abundance of Turicibacter, Terrisporobacter, Clostridium_sensu_stricto_1 and UCG-005 was higher (P < 0.05), whereas the relative abundance of Lactobacillus and Streptococcus was lower (P < 0.05) in pigs fed with the LP and VLP diets compared to the NP diet. Based on the correlation of cecal microbiota and cecal biogenic amine, the contents of tyramine, spermidine and histamine were negatively correlated with the abundance of Terrisporobacter (P < 0.01) and the content of histamine was positively correlated with the abundance of Lactobacillus (P < 0.01). Balanced with four essential amino acids, the VLP diet with crude protein levels decreased by > 4% increased the intramuscular fat content, changed the fatty acid and amino acid composition of longissimus dorsi muscle and the profile of cecum microbiota, and reduced the content of cecum bioamine, with no negative effect on the growth performance of pigs. © 2022 Society of Chemical Industry.","36263407":"ID: 36263407\nTitle: Dietary citrus pectin drives more ileal microbial protein metabolism and stronger fecal carbohydrate fermentation over fructo-oligosaccharide in growing pigs.\nAbstract: Fructo-oligosaccharide (FOS) and pectin are known soluble dietary fibers and can influence gut microbiota and consequently modulate gut health. To understand the differential impact patterns of pectin vs. FOS in modulating gut microbiota in the small and large intestine, an ileal-cannulated pig model was adopted to compare the temporal and spatial effects of FOS and citrus pectin (CP) on the gut microbiota. Sixteen terminal ileal-cannulated pigs were randomly divided into 2 groups and fed with a standard diet supplemented with either 3% FOS or 3% CP for 28 d. The CP group and FOS group showed different microbial composition, especially in the feces, with time and location as major factors affecting microbiota in the CP group, and with only location contribution in the FOS group. In the feces, relative to the FOS group, the CP group showed higher abundance of Christensenellaceae R-7 group and Ruminococcaceae UCG-010 and lower abundance of Mitsuokella and Olsenella (adjusted P < 0.05), a higher level of short-chain fatty acids and a lower level of lactate at both d 14 and 25 (P < 0.05), and more copy numbers of genes encoding key enzymes related to propionate (mmdA) and butyrate (BCoAT) production and lactate utilization (LcdA) (P < 0.05), indicating a greater degree of microbial carbohydrate fermentation. In the ileum, as compared with FOS, CP increased the bacteria with high capability of fermenting amino acids, including Escherichia-Shigella and Klebsiella (adjusted P < 0.05), and the expression of enzymes responsible for amino acid fermentation (i.e. lysine decarboxylase), as well as the amino acid fermentation products (cadaverine and tyramine) (P < 0.05), indicating a greater degree of amino acid fermentation. Overall, our results highlight a differential dynamic impact of dietary CP vs. FOS on microbial composition and metabolism in the gut. The dietary CP has a stronger ability to promote microbial amino acid fermentation in the ileum and carbohydrate fermentation in the feces than FOS. These findings provide a new insight into the role of different fibers in gut nutrition and guidelines for the choice of fibers in manipulating gut health.","36309426":"ID: 36309426\nTitle: Marination increased tyramine levels in rainbow trout fillet strips packaged under modified atmosphere.\nAbstract: Marinades are increasingly used to manufacture raw fish products. In corresponding meats, marinating is known to have a major effect on the composition of the microbiome, but the effect of marinating on fish is not known as well. This knowledge gap prompted our study of the microbial ecology and amine formation in marinated and unmarinated modified atmosphere commercially packaged rainbow trout fillet strips. According to our findings, marination increased the maximum concentrations (7-8 log CFU/g) of psychrotrophic bacteria by one logarithmic unit and led to 5 times higher average tyramine concentrations than the corresponding unmarinated product. Instead, trimethylamine concentrations were 30 times higher in the unmarinated product than those in the marinated one. According to the 16 S rRNA sequence analyses, lactic acid bacteria (LAB) predominated in the marinated strips one day after the use-by date, whereas in the unmarinated strips Fusobacteriaceae and LAB were the dominating taxa. Based on the culture-dependent analysis, Latilactobacillus fuchuensis was the prevailing LAB in both products. Since the subset of L. fuchuensis strains tested was able to produce tyramine in vitro, we hypothesise that the use of the acidic marinade activated the production of tyrosine-decarboxylating enzymes in L. fuchuensis and led to the increased tyramine concentrations.","36680969":"ID: 36680969\nTitle: An electrochemical immunosensor for the detection of Glypican-3 based on enzymatic ferrocene-tyramine deposition reaction.\nAbstract: An ultrasensitive electrochemical immunosensor based on signal amplification of the deposition of the electroactive ferrocene-tyramine (Fc-Tyr) molecule, catalyzed by horseradish peroxidase (HRP), was constructed for the detection of the liver cancer marker Glypican-3 (GPC3). Functional electroactive molecule Fc-Tyr is reported to exhibit both the enzymatic cascade catalytic activity of tyramine signal amplification (TSA) and the excellent redox properties of ferrocene. In terms of design, the low matrix effects inherent in using the magnetic bead platforms, a quasi-homogeneous system, allowed capturing the target protein GPC3 without sample pretreatment, and loading HRP to trigger the TSA, which induced a large amount of Fc-Tyr deposited on the electrode surface layer by layer as a signal probe for the detection of GPC3. The concept of Fc-Tyr as an electroactive label was validated, GPC3 biosensor exhibited high selectivity and sensitivity to GPC3 in the range of 0.1 ng mL-1-1 μg mL-1. Finally, the sensor was used simultaneously with ELISA to assess GPC3 levels in the serum of clinical liver cancer patients, and the results showed consistency, with a recovery of 98.33-105.35% and a relative standard deviation (RSD) of 4.38-8.18%, providing a theoretical basis for achieving portable, rapid and point of care testing (POCT) of tumor markers.","36899958":"ID: 36899958\nTitle: Fermented Soybean Paste Attenuates Biogenic Amine-Induced Liver Damage in Obese Mice.\nAbstract: Biogenic amines are cellular components produced by the decarboxylation of amino acids; however, excessive biogenic amine production causes adverse health problems. The relationship between hepatic damage and biogenic amine levels in nonalcoholic fatty liver disease (NAFLD) remains unclear. In this study, mice were fed a high-fat diet (HFD) for 10 weeks to induce obesity, presenting early-stage of NAFLD. We administered histamine (20 mg/kg) + tyramine (100 mg/kg) via oral gavage for 6 days to mice with HFD-induced early-stage NAFLD. The results showed that combined histamine and tyramine administration increased cleaved PARP-1 and IL-1β in the liver, as well as MAO-A, total MAO, CRP, and AST/ALT levels. In contrast, the survival rate decreased in HFD-induced NAFLD mice. Treatment with manufactured or traditional fermented soybean paste decreased biogenically elevated hepatic cleaved PARP-1 and IL-1β expression and blood plasma MAO-A, CRP, and AST/ALT levels in HFD-induced NAFLD mice. Additionally, the biogenic amine-induced reduction in survival rate was alleviated by fermented soybean paste in HFD-induced NAFLD mice. These results show that biogenic amine-induced liver damage can be exacerbated by obesity and may adversely affect life conservation. However, fermented soybean paste can reduce biogenic amine-induced liver damage in NAFLD mice. These results suggest a beneficial effect of fermented soybean paste on biogenic amine-induced liver damage and provide a new research perspective on the relationship between biogenic amines and obesity.","37499843":"ID: 37499843\nTitle: Traditional uses, phytochemistry, pharmacology, processing methods and quality control of Lindera aggregata (Sims) Kosterm: A critical review.\nAbstract: Dried root tubers of L.aggregata have been widely used in Chinese herbal medicine for thousands of years to promote qi, relieve pain, warm kidney, and disperse cold. This review aims to assess the research progress of L.aggregata, to comprehensively understand its development status, to point out the shortcomings of the existing researches, and to provide reference for further research on L.aggregata. By searching various databases for literatures on \"Lindera aggregata\", \"Linderae Radix\" and \"Lindera strychnifolia\", as well as relevant textbooks and digital documents, an overall and critical review of the subject was conducted. Through phytochemical studies on different parts of L.aggregata, about 260 compounds were isolated, including flavonoids, alkaloids, terpenes, volatile oils, and other compounds. A large number of in vivo and in vitro studies have shown that L.aggregata has a plethora of pharmacological effects such as anti-cancer, anti-arthritis, anti-bacterial, anti-oxidation, anti-diabetic nephropathy, hepatoprotective, lipid-lowering effect and so on. While the pharmacological effects of L.aggregata have been confirmed, most studies only use simple in vitro cell lines or animal disease models to evaluate their pharmacological activities. Therefore, future research should be conducted in a more comprehensive clinical manner. Further pharmacological research is also necessary to fully clarify the action mechanism of L.aggregata. It is also interesting to note that L.aggregata is often used to treat frequent urination in ancient times, but its molecular basis and mechanism of action are still unclear, and systematic studies are lacking. In terms of quality control, the source of L.aggregata is single, mostly wild, and the main medicinal part of L.aggregata is the tuber, while the yield of straight root is large. Therefore, further attention should be paid to the rapid propagation technology of L.aggregata and whether straight root can be included in medicinal use. It is also worth thinking whether sulfur-fumigation is necessary for preserving L.aggregata. As vinegar-processing is a common processing method for L. aggregata, the mechanism of such processing method remains to be investigated. In addition, in-depth research on the pharmacokinetics and long-term toxicity of L.aggregata is necessary to ensure its efficacy and safety.","37553712":"ID: 37553712\nTitle: Epstein Barr virus infection in tree shrews alters the composition of gut microbiota and metabolome profile.\nAbstract: Epstein-Barr virus (EBV) infection is a major global threat; its manifestations range from the absence of symptoms to multiorgan malignancies and various gastrointestinal diseases. Analyzing the composition and metabolomic profile of gut microbiota during acute EBV infection might be instrumental in understanding and controlling EBV. Six tree shrews were inoculated with EBV by intravenous injection. Blood was collected at regular intervals thereafter from the femoral vein to detect EBV and inflammatory biomarker. At the same time, tree shrew faeces were collected for 16 S rRNA gene sequencing and Non-targeted metabolomics analysis. 16 S rRNA gene characterization along with β diversity analysis exhibited remarkable alterations in gut microflora structure with a peak at 7 days post-infection(dpi). Some alterations in the relative richness of bacterial taxon were linked to infectious indicators. Of note, Butyricicoccus relative richness was positively linked to EBV presence in the blood and plasma, the opposite correlation was seen with Variovorax and Paramuribaculum. Non-targeted metabolomics indicated the fecal metabolome profile altered during EBV infection, particularly 7 dpi. The relative abundance of geranic acid and undecylenic acid in stool samples was positively linked to systemic inflammatory biomarkers, and an inverse relationship was reported with the estrone glucuronide, linoleic acid, protoporphyrin IX and tyramine. Collectively, EBV infection in this model correlated with changes in the composition and metabolome profile of the gut microbiota.","38421203":"ID: 38421203\nTitle: New aspects characterizing non-obese NAFLD by the analysis of the intestinal flora and metabolites using a mouse model.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) is a major public health problem due to the high incidence affecting approximately one-third of the world's population. NAFLD is usually linked to obesity and excessive weight. A subset of patients with NAFLD expresses normal or low body mass index; thus, the condition is called non-obese NAFLD or lean NAFLD. However, patients and healthcare professionals have little awareness and understanding of NAFLD in non-obese individuals. Furthermore, preclinical results from non-obese animal models with NAFLD are unclear. Gut microbiota and their metabolites in non-obese/lean-NAFLD patients differ from those in obese NAFLD patients. Therefore, we analyzed the biochemical indices, intestinal flora, and intestinal metabolites in a non-obese NAFLD mouse model established using a methionine-choline-deficient (MCD) diet. The significantly lean MCD mice had a remarkable fatty liver with lower serum triglyceride and free fatty acid levels, as well as higher alanine transaminase and aspartate transaminase levels than normal mice. 16S RNA sequencing of fecal DNA showed that the overall richness and diversity of the intestinal flora decreased in MCD mice, whereas the Firmicutes:Bacteroidota ratio was increased. g_Tuzzerella, s_Bifidobacterium pseudolongum, and s_Faecalibaculum rodentium were the predominant species in non-obese NAFLD mice. Fecal metabolomics using liquid chromatography-tandem mass spectrometry revealed the potential biomarkers for the prognosis and diagnosis of non-obese NAFLD, including high levels of tyramine glucuronide, 9,12,13-TriHOME, and pantetheine 4'-phosphate, and low levels of 3-carbamoyl-2-phenylpropionaldehyde, N-succinyl-L,L-2,6-diaminopimelate, 4-methyl-5-thiazoleethanol, homogentisic acid, and estriol. Our findings could be useful to identify and develop drugs to treat non-obese NAFLD and lean NAFLD. Patients and healthcare professionals have little awareness and understanding of NAFLD in non-obese individuals. In fact, about 40% of people with NAFLD worldwide are non-obese, and nearly one-fifth are lean. Lean NAFLD unfortunately may be unnoticed for years and remains undetected until hepatic damage is advanced and the prognosis is compromised. This study focused on the lean NAFLD, screened therapeutic agents, and biomarkers for the prognosis and diagnosis using MCD-induced male C57BL/6J mice. The metabolites tyramine glucuronide, 9,12,13-TriHOME, and pantetheine 4'-phosphate, together with the predominant flora including g_Tuzzerella, s_Bifidobacterium pseudolongum, and s_Faecalibaculum rodentium, were specific in non-obese NAFLD mice and might be used as targets for non-obese NAFLD drug exploration. This study is particularly significant for non-obese NAFLDs that need to be more actively noticed and vigilant.","38518452":"ID: 38518452\nTitle: Identification of metabolites produced by six gut commensal Bacteroidales strains using non-targeted LC-MS/MS metabolite profiling.\nAbstract: As the most abundant gram-negative bacterial order in the gastrointestinal tract, Bacteroidales bacteria have been extensively studied for their contribution to various aspects of gut health. These bacteria are renowned for their involvement in immunomodulation and their remarkable capacity to break down complex carbohydrates and fibers. However, the human gut microbiota is known to produce many metabolites that ultimately mediate important microbe-host and microbe-microbe interactions. To gain further insights into the metabolites produced by the gut commensal strains of this order, we examined the metabolite composition of their bacterial cell cultures in the stationary phase. Based on their abundance in the gastrointestinal tract and their relevance in health and disease, we selected a total of six bacterial strains from the relevant genera Bacteroides, Phocaeicola, Parabacteroides, and Segatella. We grew these strains in modified Gifu anaerobic medium (mGAM) supplemented with mucin, which resembles the gut microbiota's natural environment. Liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based metabolite profiling revealed 179 annotated metabolites that had significantly differential abundances between the studied bacterial strains and the control growth medium. Most of them belonged to classes such as amino acids and derivatives, organic acids, and nucleot(s)ides. Of particular interest, Segatella copri DSM 18205 (previously referred to as Prevotella copri) produced substantial quantities of the bioactive metabolites phenylethylamine, tyramine, tryptamine, and ornithine. Parabacteroides merdae CL03T12C32 stood out due to its ability to produce cadaverine, histamine, acetylputrescine, and deoxycarnitine. In addition, we found that strains of the genera Bacteroides, Phocaeicola, and Parabacteroides accumulated considerable amounts of proline-hydroxyproline, a collagen-derived bioactive dipeptide. Collectively, these findings offer a more detailed comprehension of the metabolic potential of these Bacteroidales strains, contributing to a better understanding of their role within the human gut microbiome in health and disease.","38588628":"ID: 38588628\nTitle: Hepatocellular carcinoma biomarkers screening based on hydrogel photonic barcodes with tyramine deposition amplified ELISA.\nAbstract: Hepatocellular carcinoma (HCC), as one of the most lethal cancers, significantly impacts human health. Attempts in this area tends to develop novel technologies with sensitive and multiplexed detection properties for early diagnosis. Here, we present novel hydrogel photonic crystal (PhC) barcodes with tyramine deposition amplified enzyme-linked immunosorbent assay (ELISA) for highly sensitive and multiplexed HCC biomarker screening. Because of the abundant amino groups of acrylic acid (AA) component, the constructed hydrogel PhC barcodes with inverse opal structure could facilitate the loading of antibody probes for subsequent detection of tumor markers. By integrating tyramine deposition amplified ELISA on the barcode, the detection signal of tumor markers has been enhanced. Based on these features, it is demonstrated that the hydrogel PhC barcodes with tyramine deposition amplified ELISA could realize highly sensitive and multiplexed detection of HCC-related biomarkers. It was found that this method is flexible, sensitive and accurate, suitable for multivariate analysis of low abundance tumor markers and future cancer diagnosis. These features make the newly developed PhC barcodes an innovation platform, which possesses tremendous potential for practical application of low abundance targets.","38623209":"ID: 38623209\nTitle: Beneath the rind: A review on the remarkable health benefits and applications of the wood apple fruit.\nAbstract: Limonia acidissima Groff, commonly referred to as the Wood apple, is a tropical fruit belonging to Rutaceae family. Indigenous to Sri Lanka, India, and Myanmar, it is extensively cultivated throughout Southeast Asia. This fruit holds a profound historical significance in traditional medicine due to its exceptional nutritional and therapeutic attributes. Wood apple pulp is significantly abundant in β-carotene, a precursor to vitamin A, and contains a substantial amount of vitamin B, including riboflavin and thiamine, as well as trace amounts of ascorbic acid (vitamin C). Moreover health-benefitting properties associated with L. acidissima, such as, antioxidant, hepatoprotective, antimicrobial, neuroprotective, antidiabetic, anti-inflammatory, anti-spermatogenic, analgesic, antiulcer, and antihyperlipidemic properties, are attributed to a diverse range of phytochemicals. These encompass polyphenolic compounds, saponins, phytosterols, tannins, triterpenoids, coumarins, amino acids, tyramine derivatives, and vitamins. From the findings of the various studies, it was observed that wood apple fruit shows significant anticancer activity by inhibiting the proliferation of cancer. Furthermore, wood apple finds wide-ranging commercial applications in the formulation of ready-to-serve beverages, syrups, jellies, chutneys, and various other food products. In summary, this review highlights the nutritional and phytochemical constituents of wood apple, depicts its antioxidant, anti-inflammatory, and anti-diabetic capabilities, and explores its potential in value-added product development. Nevertheless, it is crucial to acknowledge that the molecular mechanisms supporting these properties remain an underexplored domain. To ensure the safe integration of wood apple fruit into the realms of the food, cosmetics, and pharmaceutical sectors, rigorous clinical trials, including toxicity assessments, are required. These endeavors hold the potential to promote innovation and contribute significantly to both research and industrial sectors.","38643372":"ID: 38643372\nTitle: The gut microbiome promotes locomotion of Drosophila larvae via octopamine signaling.\nAbstract: The gut microbiome is a key partner of animals, influencing various aspects of their physiology and behaviors. Among the diverse behaviors regulated by the gut microbiome, locomotion is vital for survival and reproduction, although the underlying mechanisms remain unclear. Here, we reveal that the gut microbiome modulates the locomotor behavior of Drosophila larvae via a specific neuronal type in the brain. The crawling speed of germ-free (GF) larvae was significantly reduced compared to the conventionally reared larvae, while feeding and excretion behaviors were unaffected. Recolonization with Acetobacter and Lactobacillus can fully and partially rescue the locomotor defects in GF larvae, respectively, probably due to the highest abundance of Acetobacter as a symbiotic bacterium in the larval gut, followed by Lactobacillus. Moreover, the gut microbiome promoted larval locomotion, not by nutrition, but rather by enhancing the brain levels of tyrosine decarboxylase 2 (Tdc2), which is an enzyme that synthesizes octopamine (OA). Overexpression of Tdc2 rescued locomotion ability in GF larvae. These findings together demonstrate that the gut microbiome specifically modulates larval locomotor behavior through the OA signaling pathway, revealing a new mechanism underlying larval locomotion regulated by the gut microbiome.","38738766":"ID: 38738766\nTitle: Cultivated Enterococcus faecium B6 from children with obesity promotes nonalcoholic fatty liver disease by the bioactive metabolite tyramine.\nAbstract: Gut microbiota plays an essential role in nonalcoholic fatty liver disease (NAFLD). However, the contribution of individual bacterial strains and their metabolites to childhood NAFLD pathogenesis remains poorly understood. Herein, the critical bacteria in children with obesity accompanied by NAFLD were identified by microbiome analysis. Bacteria abundant in the NAFLD group were systematically assessed for their lipogenic effects. The underlying mechanisms and microbial-derived metabolites in NAFLD pathogenesis were investigated using multi-omics and LC-MS/MS analysis. The roles of the crucial metabolite in NAFLD were validated in vitro and in vivo as well as in an additional cohort. The results showed that Enterococcus spp. was enriched in children with obesity and NAFLD. The patient-derived Enterococcus faecium B6 (E. faecium B6) significantly contributed to NAFLD symptoms in mice. E. faecium B6 produced a crucial bioactive metabolite, tyramine, which probably activated PPAR-γ, leading to lipid accumulation, inflammation, and fibrosis in the liver. Moreover, these findings were successfully validated in an additional cohort. This pioneering study elucidated the important functions of cultivated E. faecium B6 and its bioactive metabolite (tyramine) in exacerbating NAFLD. These findings advance the comprehensive understanding of NAFLD pathogenesis and provide new insights for the development of microbe/metabolite-based therapeutic strategies.","38788722":"ID: 38788722\nTitle: Enterococcus-derived tyramine hijacks α2A-adrenergic receptor in intestinal stem cells to exacerbate colitis.\nAbstract: Inflammatory bowel disease (IBD) is characterized by dysbiosis of the gut microbiota and dysfunction of intestinal stem cells (ISCs). However, the direct interactions between IBD microbial factors and ISCs are undescribed. Here, we identify α2A-adrenergic receptor (ADRA2A) as a highly expressed GPCR in ISCs. Through PRESTO-Tango screening, we demonstrate that tyramine, primarily produced by Enterococcus via tyrosine decarboxylase (tyrDC), serves as a microbial ligand for ADRA2A. Using an engineered tyrDC-deficient Enterococcus faecalis strain and intestinal epithelial cell-specific Adra2a knockout mice, we show that Enterococcus-derived tyramine suppresses ISC proliferation, thereby impairing epithelial regeneration and exacerbating DSS-induced colitis through ADRA2A. Importantly, blocking the axis with an ADRA2A antagonist, yohimbine, disrupts tyramine-mediated suppression on ISCs and alleviates colitis. Our findings highlight a microbial ligand-GPCR pair in ISCs, revealing a causal link between microbial regulation of ISCs and colitis exacerbation and yielding a targeted therapeutic approach to restore ISC function in colitis.","38965418":"ID: 38965418\nTitle: Gut microbiota metabolite tyramine ameliorates high-fat diet-induced insulin resistance via increased Ca2+ signaling.\nAbstract: The gut microbiota and their metabolites are closely linked to obesity-related diseases, such as type 2 diabetes, but their causal relationship and underlying mechanisms remain largely elusive. Here, we found that dysbiosis-induced tyramine (TA) suppresses high-fat diet (HFD)-mediated insulin resistance in both Drosophila and mice. In Drosophila, HFD increases cytosolic Ca2+ signaling in enterocytes, which, in turn, suppresses intestinal lipid levels. 16 S rRNA sequencing and metabolomics revealed that HFD leads to increased prevalence of tyrosine decarboxylase (Tdc)-expressing bacteria and resulting tyramine production. Tyramine acts on the tyramine receptor, TyrR1, to promote cytosolic Ca2+ signaling and activation of the CRTC-CREB complex to transcriptionally suppress dietary lipid digestion and lipogenesis in enterocytes, while promoting mitochondrial biogenesis. Furthermore, the tyramine-induced cytosolic Ca2+ signaling is sufficient to suppress HFD-induced obesity and insulin resistance in Drosophila. In mice, tyramine intake also improves glucose tolerance and insulin sensitivity under HFD. These results indicate that dysbiosis-induced tyramine suppresses insulin resistance in both flies and mice under HFD, suggesting a potential therapeutic strategy for related metabolic disorders, such as diabetes.","39095501":"ID: 39095501\nTitle: Association of plant-based diet indexes with the metabolomic profile.\nAbstract: Plant-based diets have gained attention for their potential benefits on both human health and environmental sustainability. The objective of this study was to investigate the association of plant-based dietary patterns with the endogenous metabolites of healthy individuals and identify metabolites that may act as mediators of the associations between dietary intake and modifiable disease risk factors. Adherence to plant-based dietary patterns was assessed for 170 healthy adults using plant-based diet indexes (PDI). Individuals with higher healthful PDI had lower BMI and fasting glucose and higher HDL-C, while those with higher unhealthful PDI had higher BMI, triacylglycerol and fasting glucose and lower HDL-C. Unhealthful PDI was associated with higher levels of several amino acids and biogenic amines previously associated with cardiometabolic diseases and an opposite pattern was observed for healthful PDI. Furthermore, healthful PDI was associated with higher levels of glycerophosphocholines containing very long-chain fatty acids. Glutamate, isoleucine, proline, tyrosine, α-aminoadipate and kynurenine had a statistically significant mediation effect on the associations between PDI scores and LDL-C, HDL-C and fasting glucose. These findings contribute to the growing evidence supporting the role of plant-based diets in promoting metabolic health and shed light on the potential mechanisms explaining their beneficial health effects.","39153554":"ID: 39153554\nTitle: Exploring the chemistry, biological effects, and mechanism insights of natural coumaroyltyramine: First report.\nAbstract: Today, pharmaceutical drugs have been shown to have serious side effects, while the bioactive components of botanical plants are proven to be effective in the treatment of several diseases marked by enhanced oxidative stress and mild inflammation, often associated with minimal adverse events. Coumaroyltyramine, designated by various nomenclatures such as paprazine, N-p-trans-coumaroyltyramine, p-coumaroyltyramine and N-p-coumaroyltyramine, could be a promising bioactive ingredient to address health issues thanks to its powerful anti-inflammatory and antioxidant effects. This review represents the first in-depth analysis of coumaroyltyramine, an intriguing phenylpropanoid substance found in many species of plants. In fact, an in-depth examination of coumaroyltyramine's biological characteristics, chemical attributes, and synthesis process has been undertaken. All previous research relating to the discovery, extraction, biosynthesis, and characterization of the biologically and pharmacologically active properties of coumaroyltyramine has been reviewed and taken into consideration in this analysis. All articles published in a peer-reviewed English-language journal were examined between the initial compilations of the appropriate database until February 12, 2024. A variety of phytochemicals revealed that coumaroyltyramine is a neutral amide of hydroxycinnamic acid that tends to concentrate in plants as a reaction against infection caused by pathogens and is extracted from several medicinal herbs such as Cannabis sativa, Solanum melongena, Allium bakeri, Annona cherimola, Polygonatum zanlanscianense, and Lycopersicon esculentum. Thanks to its effectiveness in suppressing the effect of the enzyme α-glucosidase, coumaroltyramine has demonstrated antihyperglycemic activity and could have an impact on diabetes and metabolic disorders. It has considerable anti-inflammatory and antioxidant effects. These results were obtained through biological and pharmacological studies in silico, in vivo, and in vitro. In addition, coumaroyltyramine has demonstrated hypocholesterolemic and neuroprotective benefits, thereby diminishing heart and vascular disease incidence and helping to prevent neurological disorders. Other interesting properties of coumaroltyramine include anticancer, antibacterial, anti-urease, antifungal, antiviral, and antidysmenorrheal activities. Targeted pathways encompass activity at different molecular levels, notably through induction of endoplasmic reticulum stress-dependent apoptosis, arrest of the cell cycle, and inhibition of the growth of cancer cells, survival, and proliferation. Although the findings from in silico, in vivo, and in vitro experiments illustrate coumaroyltyramine's properties and modes of action, further research is needed to fully exploit its therapeutic potential. To improve our understanding of the compound's pharmacodynamic effects and pharmacokinetic routes, large-scale research should first be undertaken. To determine whether coumaroyltyramine is clinically safe and effective, further studies are required in the clinical and toxicological fields. This upcoming research will be crucial to achieving the overall potency of this substance as a natural drug and in terms of its potential synergies with other drugs.","39180084":"ID: 39180084\nTitle: Bacillus species are core microbiota of resistant maize cultivars that induce host metabolic defense against corn stalk rot.\nAbstract: Microbes colonizing each compartment of terrestrial plants are indispensable for maintaining crop health. Although corn stalk rot (CSR) is a severe disease affecting maize (Zea mays) worldwide, the mechanisms underlying host-microbe interactions across vertical compartments in maize plants, which exhibit heterogeneous CSR-resistance, remain largely uncharacterized. Here, we investigated the microbial communities associated with CSR-resistant and CSR-susceptible maize cultivars using multi-omics analysis coupled with experimental verification. Maize cultivars resistant to CSR reshaped the microbiota and recruited Bacillus species with three phenotypes against Fusarium graminearum including niche pre-emption, potential secretion of antimicrobial compounds, and no inhibition to alleviate pathogen stress. By inducing the expression of Tyrosine decarboxylase 1 (TYDC1), encoding an enzyme that catalyzes the production of tyramine and dopamine, Bacillus isolates that do not directly suppress pathogen infection induced the synthesis of berberine, an isoquinoline alkaloid that inhibits pathogen growth. These beneficial bacteria were recruited from the rhizosphere and transferred to the stems but not grains of the CSR-resistant plants. The current study offers insight into how maize plants respond to and interact with their microbiome and lays the foundation for preventing and treating soil-borne pathogens.

The aim of this study was to assess MCT4 expression in primary tumor and liver oligometastases, investigate its impact on immune cell infiltration and its prognostic value for CLO patients undergoing liver resection. We retrospectively selected 135 CLO patients who underwent curative liver resection between June 1999 and December 2016, and samples included 74 primary tumor tissues and 122 liver metastases. Immunohistochemistry (IHC) was performed to detect MCT4 expression in paraffin-embedded specimens and tyramine signal amplification (TSA) was used to detect the density of tumor-infiltrating lymphocytes, including CD3 + , CD8 + and Foxp3 + . Recurrence-free survival (RFS) and overall survival (OS) were analyzed using the Kaplan-Meier method and log-rank test, and independent prognostic factors were identified with Cox regression modeling. Survival analysis indicated that CLO patients with low MCT4 expression had better 3-year RFS and 3-year OS rates than those with high MCT4 expression. Multivariate analysis indicated that high MCT4 expression was independently associated with poor RFS and OS. High MCT4 expression was associated with a lower number of intratumoral CD3 + /CD8 + T cells and was associated with higher Foxp3 + T cells infiltration. Patients with low MCT4 expression and high levels of differential immune infiltration had longer survival. MCT4 overexpression was associated with an unfavorable prognosis in patients with CLO and MCT4 expression level had an impact on intratumoral immune infiltration degree. A novel parameter that combined MCT4 expression level and differential immune infiltration level was constructed to stratify patients with CLO into different risk groups.","39457871":"ID: 39457871\nTitle: GnRH Immunocastration in Male Xizang Sheep: Impacts on Rumen Microbiome and Metabolite Profiles for Enhanced Health and Productivity.\nAbstract: Castration is a prevalent and indispensable practice in sheep husbandry, aiding in enhancing meat quality, mitigating aggressive behavior, and managing unwanted reproduction. Nevertheless, the conventional surgical castration procedure poses several challenges, including heightened stress and pain, detrimental impacts on animal welfare, and diminished economic efficacy in farming operations. Consequently, immunocastration methods, serving as substitutes for surgical castration, are progressively finding application in livestock. The rumen, an essential and distinctive digestive and absorptive organ in ruminants, has been associated with enhanced meat quality and productive performance following castration in previous research studies, albeit fewer investigations have explored the potential impacts of GnRH immunization on the rumen's internal milieu in sheep post-de-escalation. Hence, the present study delved into evaluating the impact of GnRH immunocastration on the rumen microbiome and metabolomics in male Xizang sheep. This was achieved through the establishment of a GnRH immunocastration animal model and the collection of rumen fluid for microbiological and comprehensive metabolomics investigations. The outcomes of this investigation unveiled that the impact of GnRH immunocastration on body weight gain was more pronounced during the achievement of the castration objective. In addition, the Firmicutes-to-Bacteroidota ratio in the immune male (IM) group exceeded that of the control group (EM), suggesting that GnRH immunodeficiency may enhance the digestion and absorption of feed in male Xizang sheep. At the taxonomic level, the elevated presence of Prevotella and Quinella bacteria in the IM group compared to the EM group indicated that castration influenced a segment of the rumen microbiota in male Xizang sheep, thereby bolstering the digestive and metabolic efficacy of the rumen concerning nutrient utilization, particularly in the breakdown and absorption of proteins, carbohydrates, and lipids, ultimately expediting the fattening process and weight gain in male Xizang sheep following castration. Moreover, analysis of ruminal fluid metabolomics revealed that GnRH immunization had notable impacts on certain metabolites in the ruminal fluid of male Xizang sheep, with metabolites like 5-hydroxyindole acetic acid and 3-hydroxyindole acetic acid showing significant downregulation in the IM group compared to the EM group, while niacin and tyramine exhibited significant upregulation. These findings indicate a profound influence of GnRH immunization on the maintenance of ruminal equilibrium and ruminal health (including the health of ruminal epithelial cells). This study validates that GnRH immunocastration not only achieves the objectives of castration but also enhances ruminal health in male Xizang sheep, thus laying a foundational theoretical basis for the application and dissemination of GnRH immunocastration technology.","39530356":"ID: 39530356\nTitle: Pathobiont and symbiont contribute to microbiota homeostasis through Malpighian tubules-gut countercurrent flow in Bactrocera dorsalis.\nAbstract: Host-gut microbiota interactions are more complex than good or bad. Both gut symbiotic bacteria and pathobionts can provide essential functions to their host in one scenario and yet be detrimental to host health in another. So, these gut-dwelling bacteria must be tightly controlled to avoid harmful effects on the host. However, how pathobionts and other symbiotic bacteria coordinate to establish a host immune defense system remains unclear. Here, using a Tephritidae fruit fly Bactrocera dorsalis, we report that both pathobionts and other gut symbiotic bacteria release tyramine, which is recognized by the host insects. These tyramines induce the formation of insect-conserved Malpighian tubules-gut countercurrent flow upon bacterial infection, which requires tyramine receptors and aquaporins. At the same time, pathobionts but not gut symbiotic bacteria induce the generation of reactive oxygen species, which are preserved by the countercurrent flow, promoting bacteria elimination through increasing gut peristalsis. More importantly, our results show that the Malpighian tubules-gut countercurrent flow maintains proper microbiota composition. Our work suggests a model where pathobiont-induced reactive oxygen species are preserved by Malpighian tubules-gut countercurrent flow involving both pathobionts and symbiotic bacteria. Furthermore, our work provides a Malpighian tubules-gut interaction that ensures efficient maintenance of the gut microbiota.","39593339":"ID: 39593339\nTitle: Provolone del Monaco PDO cheese: Lactic microflora, biogenic amines and volatilome characterization.\nAbstract: One commercial production run of Provolone del Monaco - a long-ripened pasta filata cheese - was followed up to the end of ripening for a total of 20 samples. 371 LAB isolates were subject to genetic characterization followed by 16S rRNA gene sequencing. The dominant species were Lacticaseibacillus casei/paracasei (19.4 %), Streptococcus macedonicus (19.1 %) and Enterococcus faecalis (13.2 %). Strains were screened for features of technological interest or safety relevance. Tyramine-producing cultures were quite common, above all within enterococci. By MALDI TOF Mass Spectrometry, one Lactococcus lactis and one Enterococcus faecium strain proved to be bacteriocin producers. Four further cheese wheels from the same production run at 623 days of ripening were evaluated for volatile organic compounds, biogenic amines, and bacterial community by metagenomic sequencing. Three individual wheel samples shared a rather similar microbiome with Lactobacillus delbrueckii and Streptococcus thermophilus as the most represented species, while the fourth wheel appeared wholly different being dominated by Lentilactobacillus buchneri and St. infantarius. Additionally, this sample had the greatest content of biogenic amines and a different VOCs composition. Given the variance seen among cheese wheels processed and ripened under the same conditions, the search for adjunct cultures in the production of this cheese seems to be of utmost importance.","39596410":"ID: 39596410\nTitle: Diversity of Neurotransmitter-Producing Human Skin Commensals.\nAbstract: Recent findings indicate that human microbiota can excrete trace amines, dopamine, and serotonin. These neurotransmitters (NTs) can either affect classical neurotransmitter signaling or directly trigger trace amine-associated receptors (TAARs), with still unclear consequences for host physiology. Compared to gut microbiota, less information is available on the role of skin microbiota in NT production. To explore this, 1909 skin isolates, mainly from the genera Staphylococcus, Bacillus, and Corynebacterium, were tested for NT production. Only 6.7% of the isolates were capable of producing NTs, all of which belonged to the Staphylococcus genus. Based on substrate specificity, we identified two distinct profiles among the NT producers. One group primarily produced tryptamine (TRY) and phenylethylamine (PEA), while the other mainly produced tyramine (TYM) and dopamine (Dopa). These differing production profiles could be attributed to the activity of two distinct aromatic amino acid decarboxylase enzymes, SadA and TDC, responsible for generating the TRY/PEA and TYM/Dopa product spectra, respectively. SadA and TDC orthologues differ in structure and size; SadA has approximately 475 amino acids, whereas the TDC type consists of about 620 amino acids. The genomic localization of the respective genes also varies: tdc genes are typically found in small, conserved gene clusters, while sadA genes are not. The heterologous expression of sadA and tdc in Escherichia coli yielded the same product spectrum as the parent strains. The possible effects of skin microbiota-derived NTs on neuroreceptor signaling in the human host remain to be investigated.","39638856":"ID: 39638856\nTitle: Brain physiology during photoperiod-related caste determination in the primitively eusocial wasp Polistes jokahamae.\nAbstract: Adult females of the primitively eusocial wasp Polistes jokahamae can change caste in response to photoperiod length. Short-day photoperiod females store more lipids but have less developed ovaries for hibernation (becoming gynes), whereas long-day photoperiod females have fewer lipid stores but more developed ovaries under queenless conditions (becoming egg-laying workers). To explore the physiological mechanisms underlying photoperiod-related caste determination, analyses of gene expression levels in the brains of short- or long-day females were performed. Results suggest that short-day females may exhibit higher expression of genes involved in tryptophan metabolism, insulin signaling, and nutrition, including the digestion of sugars and lipids, and production of royal jelly proteins. Oral administration of tryptophan resulted in a positive correlation between tryptophan levels in the brain and lipid stores in the abdomen, suggesting that tryptophan promotes lipid storage in gynes. Long-day females showed enhanced expression of genes involved in tyramine/dopamine syntheses, epidermal growth factor receptor, insulin degradation, and oogenesis. In these females, tyramine administration increased the brain levels of tyramine and dopamine, and activated initial ovarian development under queenless conditions. Together, these results indicate that photoperiod-related caste determination in P. jokahamae may involve gene expression pathways similar to those involved in caste determination during the preimaginal stage in other Polistes species.","39668719":"ID: 39668719\nTitle: Digging deep for nutrients and metabolites derived from high dietary protein intake and their potential functions in metabolic health.\nAbstract: Intake of high quantities of dietary proteins sourced from dairy, meat or plants can affect body weight and metabolic health in humans. To improve our understanding of how this may be achieved, we reviewed the data related to the availability of nutrients and metabolites in the faeces, circulation and urine. All protein sources (≥20% by energy) increased faecal levels of branched-chain fatty acids and ammonia and decreased the levels of butyrate. Some metabolites responded to dairy and meat proteins (branched-chain amino acids) as well as dairy and plant proteins (p-cresol), which were increased in faecal matter. Specific to dairy protein intake, the faecal levels of acetate, indole and phenol were increased, whereas plant protein intake specifically increased the levels of kynurenine and tyramine. Meat protein intake increased the faecal levels of methionine, cysteine and alanine and decreased the levels of propionate and acetate. The metabolite profile in the faecal matter following dairy protein intake mirrored availability in circulation or urine. These findings provide an understanding of the contrasting gut versus systemic effects of different dietary proteins, which we know to show different physiological effects. In this regard, we provide directions to determining the mechanisms for the effects of different dietary proteins.","39684925":"ID: 39684925\nTitle: Functional Analysis of TAAR1 Expression in the Intestine Wall and the Effect of Its Gene Knockout on the Gut Microbiota in Mice.\nAbstract: Currently, the TAAR1 receptor has been identified in various cell groups in the intestinal wall. It recognizes biogenic amine compounds like phenylethylamine or tyramine, which are products of decarboxylation of phenylalanine and tyrosine by endogenous or bacterial decarboxylases. Since several gut bacteria produce these amines, TAAR1 is suggested to be involved in the interaction between the host and gut microbiota. The purpose of this present study was to clarify the TAAR1 function in the intestinal wall and estimate the TAAR1 gene knockout effect on gut microbiota composition. By analyzing public transcriptomic data of the GEO repository, we identified TAAR1 expression in enterocytes, enteroendocrine cells, tuft cells, and myenteric neurons in mice. The analysis of genes co-expressed with TAAR1 in enteroendocrine cells allows us to suggest the TAAR1 involvement in enteroendocrine cell maturation. Also, in myenteric neurons, we identified the co-expression of TAAR1 with calbindin, which is specific for sensory neurons. The 16S rRNA gene-based analysis of fecal microbiota revealed a slight but significant impact of TAAR1 gene knockout in mice on the gut microbial community, which manifests in the higher diversity, accompanied by low between-sample variability and reorganization of the microbial co-occurrence network.","39963326":"ID: 39963326\nTitle: Dysbiosis and Metabolic Dysregulation of Salivary Microbiota in Schizophrenia.\nAbstract: Schizophrenia (SZ) is a chronic, severe mental disorder that presents significant challenges to diagnosis and effective treatment. Emerging evidence suggests that gut microbiota may play a role in the disease's pathogenesis. However, fewer studies have directly investigated the potential links between oral microbiota and SZ. This study aimed to explore the relationship between salivary microbiota dysbiosis and SZ, examining microbial and metabolic alterations that may contribute to SZ pathophysiology. Salivary samples from 30 hospitalized patients diagnosed with SZ and 10 healthy controls were collected. The microbial and metabolic profiles were analyzed using 16S rRNA gene sequencing and metabolomic profiling. Clinical parameters, including oral health status, were also evaluated to minimize variability in sampling. Patients with SZ exhibited significantly poorer oral health compared to healthy controls, with more missing teeth and worse periodontal status. Microbiota sequencing revealed notable alterations in the overall structure and composition of the salivary microbiome in SZ patients, characterized by increased abundance of specific genera such as Neisseria and Porphyromonas. Metabolomic analysis indicated significant differences between the SZ and control groups, with upregulation of key metabolic pathways, including \"β-alanine metabolism\" and \"vitamin digestion and absorption\". Correlations between microbial dysbiosis and elevated levels of certain metabolites, such as L-methionine sulfoxide (L-MetO) and tyramine, were observed, suggesting links to oxidative stress. The study highlights the presence of significant dysbiosis and metabolic dysfunction in the salivary microbiota of SZ patients, suggesting that alterations in the oral microbiome may contribute to SZ pathogenesis. These results provide new insights into potential diagnostic biomarkers and therapeutic targets for SZ. Further studies with larger sample sizes are required to validate these findings.","40001178":"ID: 40001178\nTitle: Study on the mechanism of Shuanghe decoction against steroid-induced osteonecrosis of the femoral head: insights from network pharmacology, metabolomics, and gut microbiota.\nAbstract: Steroid-induced osteonecrosis of the femoral head (SONFH) is a challenging and debilitating orthopedic condition with a rising incidence in recent years. Shuanghe Decoction (SHD), a traditional Chinese medicine formula, has shown significant efficacy in treating SONFH, though its underlying mechanisms remain unclear. This study aims to elucidate the therapeutic effects and potential mechanisms of SHD on SONFH through in vivo experiments, combined with network pharmacology, metabolomics, and gut microbiota analysis. Forty male Sprague-Dawley rats (300 ± 20 g) were randomly assigned to four groups: Control, Model, SHD-L, and SHD-H, with 10 rats each. SONFH was induced in all groups except the Control group using lipopolysaccharide and methylprednisolone. The SHD-L and SHD-H groups were treated with Shuanghe decoction at doses of 4.86 g/kg/day and 9.72 g/kg/day, respectively, for eight weeks. Bone morphology, pathological changes, and osteogenic factors were evaluated using Micro-CT, histological staining, and immunohistochemistry. Network pharmacology, metabolomics, and gut microbiota analyses were conducted to explore SHD's mechanisms. SHD improved bone morphology and increased osteogenic factor expression (RUNX2, OCN, COL-I). Network pharmacology indicated that metabolic pathways play a key role in SHD's therapeutic effects. Metabolomic analysis identified 14 differential metabolites, including 21-hydroxypregnenolone and tyramine, which were restored to normal levels by SHD. Gut microbiota analysis revealed that SHD modulated bacterial abundance, particularly Verrucomicrobia, Allobaculum, and Burkholderiales. A comprehensive network identified two key metabolites (tyramine, 21-hydroxypregnenolone), seven targets (CYP19A1, CYP1A2, CYP1B1, CYP2C9, CYP3A4, MIF, and HSD11B1), two metabolic pathways (tyrosine metabolism, steroid hormone biosynthesis), and four bacterial taxa (Jeotgalicoccus, Clostridium, Corynebacterium, rc4-4) as central to SHD against SONFH. SHD alleviates SONFH by reshaping gut microbiota, reversing metabolic imbalances, and enhancing osteogenesis. Our findings provide novel insights into the pharmacological mechanisms of SHD, laying a foundation for its clinical application in treating SONFH.","40004997":"ID: 40004997\nTitle: Dietary Patterns and Migraine: Insights and Impact.\nAbstract: Migraine is a prevalent neurological disorder characterized by significant disability and triggered by various factors, including dietary habits. This review explores the complex relationship between diet and migraine, highlighting both triggering and protective roles of dietary patterns and specific nutrients. Evidence suggests that certain foods, such as alcohol, caffeine, chocolate, MSG, nitrates, and tyramine, can trigger migraines in susceptible individuals. Conversely, dietary interventions, including carbohydrate-restricted diets, ketogenic diets, vitamin D3 supplementation, omega-3 fatty acids, Mediterranean dietary patterns, and increased water intake, have shown potential in reducing migraine frequency and severity. Observational studies also indicate that maintaining a healthy diet, rich in fruits and vegetables and low in processed foods, is associated with better migraine outcomes. The effectiveness of these interventions varies among individuals, underscoring the importance of personalized approaches. Future studies should further explore the role of diet in migraine management, focusing on randomized trials to establish causality and refine dietary recommendations for patients.","40022152":"ID: 40022152\nTitle: Roux-en-Y gastric bypass-associated fecal tyramine promotes colon cancer risk via increased DNA damage, cell proliferation, and inflammation.\nAbstract: Fecal abundances of Enterobacteriaceae and Enterococcaceae are elevated in patients following Roux-en-Y gastric bypass (RYGB) surgery. Concurrently, fecal concentrations of tyramine, derived from gut bacterial metabolism of tyrosine and/or food, increased post-RYGB. Furthermore, emerging evidence suggests that RYGB is associated with increased colorectal cancer (CRC) risk. However, the causal link between RYGB-associated microbial metabolites and CRC risk remains unclear. Hence, this study investigated the tyrosine metabolism of Enterobacteriaceae and Enterococcaceae strains isolated from patients post-RYGB and explored the causal effects of tyramine on the CRC risk and tumorigenesis using both human colonic cancer cell line (HCT 116) and wild-type and ApcMin/+ mice. We isolated 31 bacterial isolates belonging to Enterobacteriaceae and Enterococcaceae families from the feces of patients with RYGB surgery. By culturing the isolates in tyrosine-supplemented medium, we found that Citrobacter produced phenol as a main product of tyrosine, whereas Enterobacter and Klebsiella produced 4-hydroxyphenylacetate, Escherichia produced 4-hydroxyphenyllactate and 4-hydroxyphenylpyruvate, and Enterococcus and two Klebsiella isolates produced tyramine. These observations suggested the gut bacterial contribution to increased fecal concentrations of tyramine post-RYGB. We subsequently evaluated the impact of tyramine on CRC risk and development. Tyramine induced necrosis and promoted cell proliferation and DNA damage of HCT 116 cells. Daily oral administration of tyramine for 49 days to wild-type mice resulted in visible adenomas in 5 out of 12 mice, accompanied by significantly enhanced DNA damage (γH2AX +) and an increased trend of cell proliferation (Ki67 +) in the ileum, along with an upregulated expression of the cell division cycle gene (Cdc34b) in the colon. To evaluate the impact of tyramine on intestinal tumor growth, we treated ApcMin/+ mice with the same doses of tyramine and duration. These mice showed larger colonic tumor size and increased intestinal cell proliferation and inflammation (e.g., increased mRNA expression of IL-17A and higher number of Ly6G + neutrophils) compared to water-treated ApcMin/+ control mice. Our results collectively suggested that RYGB-associated fecal bacteria could contribute to tyramine production and tyramine increased CRC risk by increasing DNA damage, cell proliferation, and pro-inflammatory responses of the gut. Monitoring and modulating tyramine concentrations in high-risk individuals could aid CRC prognosis and management.

Hemp hull powder is a rich source of two bioactive compounds, N-trans-caffeoyl tyramine (NCT) and N-trans-feruloyl tyramine (NFT), with potential gut health benefits. Methods: The study participants included 23 male and female cyclists. A three-arm randomized, placebo-controlled, double-blind, crossover design was used with two 2-week supplementation periods and 2-week washout periods. Supplement bars provided 20, 5, or 0 g/d of hemp hull powder. Participants engaged in an intensive 2.25 h cycling bout at the end of each of the three supplementation periods. Five blood samples were collected before and after supplementation (overnight fasted state), and at 0 h-, 1.5 h-, and 3 h-post-exercise. Five-hour urine samples were collected pre-supplementation and post-2.25 h cycling after ingesting a sugar solution containing 5 g of lactulose, 100 mg of 13C mannitol, and 1.9 g of mannitol in 450 mL of water. An increase in the post-exercise lactulose/13C mannitol ratio (L:13CM) was used as the primary indicator of altered gut permeability. Other outcome measures included muscle damage biomarkers (serum creatine kinase, myoglobin), serum cortisol, complete blood cell counts, and shifts in plasma metabolites using untargeted metabolomics. Results: No trial differences were found for L:13CM, cortisol, blood cell counts, and muscle damage biomarkers. Orthogonal partial least-squares discriminant analysis (OPLSDA) showed distinct trial differences when comparing high- and low-dose hemp fiber compared to placebo supplementation (R2Y = 0.987 and 0.995, respectively). Variable Importance in Projection (VIP) scores identified several relevant metabolites, including 3-hydroxy-4-methoxybenzoic acid (VIP = 1.9), serotonin (VIP = 1.5), 5-hydroxytryptophan (VIP = 1.4), and 4-methoxycinnamic acid (VIP = 1.4). Mummichog analysis showed significant effects of hemp fiber intake on multiple metabolic pathways, including alpha-linolenic acid, porphyrin, sphingolipid, arginine and proline, tryptophan, and primary bile acid metabolism. Conclusions: Hemp fiber intake during a 2-week supplementation period did not have a significant effect on post-exercise gut permeability in cyclists (2.25 h cycling bout) using urine sugar data. On the contrary, untargeted metabolomics showed that the combination of consuming nutrient-rich hemp fiber bars and exercising for 135 min increased levels of beneficial metabolites, including those derived from the gut in healthy cyclists.","40294666":"ID: 40294666\nTitle: p-Synephrine ameliorates non-alcoholic fatty liver disease by regulating liver-adipose axis via AMPK/NF-kappa B pathway.\nAbstract: Citrus aurantium L. var. amara Engl. is a folk medicine and dietary supplement popularly used in alleviating indigestion due to food retention and obesity. p-Synephrine, a principal proto-alkaloid in Citrus aurantium L. var. amara Engl., is extensively utilized due to its numerous benefits, particularly its potential to ameliorate obesity. Previous studies of our research demonstrated that p-synephrine had the potential to alleviate insulin resistance (IR) and liver lipid accumulation caused by high-fat diet (HFD), as well as enlargement of cells in adipose tissue. However, the effects of p-synephrine in ameliorating non-alcoholic fatty liver disease (NAFLD) were still unclear. To explore the effects of p-synephrine on HFD-induced NAFLD and its mechanisms. NAFLD mice were developed by HFD feeding and treated with p-synephrine once a day for 21 weeks. The protective effects of p-synephrine against NAFLD and its mechanisms were evaluated by OGTT, ITT, biochemical index measurements, H&E, immunofluorescence, Sirius red staining, oil red O staining, immunohistochemistry, RT-qPCR, Western blot, network pharmacology, and molecular docking assays. The results of network pharmacology suggested that AMPK-α1 might be the core target, and AMPK and insulin signaling pathways might be the key regulatory pathways of p-synephrine to alleviate NAFLD. Molecular docking confirmed AMPK-α1 as a probable direct molecular target. p-Synephrine significantly reduced HFD-induced weight gain of the body, liver, and iWAT. It improved glucose tolerance, insulin tolerance and lipid metabolism disorders caused by HFD. Serum levels of NO, TNF-α, and IL-6 in NAFLD mice were suppressed. AST, ALT, and HYP levels in serum and liver were inhibited. Morphological observation showed p-synephrine alleviated hepatic steatosis and fibrosis. p-Synephrine administration also significantly inhibited hepatic de novo lipogenesis (DNL), as evidenced by its regulation of non-esterified fatty acid (NEFA) and TG contents, as well as SREBP-1c, FASN, and ACC1 mRNA expression levels. p-Synephrine also reversed HFD-induced histopathological changes in iWAT, promoted iWAT browning by increasing UCP1 and PGC-1α expression. Simultaneously, p-synephrine intervention markedly increased phosphorylation levels of IRS-1, PI3K, and Akt, and protein expression of GLUT-4 in iWAT and liver. Expression of TNF-α, IL-6, and IL-1β and NF-κB activation in iWAT and liver were attenuated through the treatment of p-synephrine. Further assays showed that p-synephrine intervention potently regulated AMPK pathway in iWAT and liver of mice. This investigation proposed that p-synephrine had the potential to ameliorate HFD-induced NAFLD by regulating liver-adipose axis through AMPK/NF-κB pathway.","40306360":"ID: 40306360\nTitle: Biogenic amines in honey bee cognition: neurochemical pathways and stress impacts.\nAbstract: Honey bees, as indispensable pollinators, rely on sophisticated neuromodulatory networks to regulate learning, memory, and social behaviors, all essential for colony function, ecosystem stability, and global agricultural systems. Biogenic amines octopamine, dopamine, serotonin, and tyramine are key modulators of these cognitive and behavioral processes, regulating foraging efficiency, navigational precision, and division of labor. However, we argue that anthropogenic stressors, including pesticides, pollutants, heavy metals, and microbiome dysbiosis, disrupt aminergic pathways by impairing neurotransmitter synthesis and neuronal signaling, leading to maladaptive behaviors and colony collapse. Recent discoveries expand this paradigm, revealing those biogenic amines in floral nectar act as exogenous neurochemicals, potentially altering pollinator behavior; however, their interaction with agrochemicals remains underexplored. While most studies focus on Apis mellifera, we caution that cautious extrapolation to wild and solitary bees is critical, given the evolutionary conservation of aminergic signaling across insect taxa. Cognitive deficits observed in managed honeybees likely extend to wild pollinators, threatening pollination network resilience and food security. To address these gaps, we advocate for CRISPR-based neurogenetic tools and multi-omics approaches to dissect stress susceptibility and biogenic amine (BA) regulation. Integrating neurobiology, ecotoxicology, and conservation science is imperative to develop precision strategies that mitigate anthropogenic threats, safeguard biodiversity, and stabilize global agriculture.","40362077":"ID: 40362077\nTitle: Preliminary Multi-Omics Insights into Green Alternatives to Antibiotics: Effects of Pulsatilla chinensis, Acer truncatum, and Clostridium butyricum on Gut Health and Metabolic Regulation in Chickens.\nAbstract: Antibiotic resistance has become a global health concern, driving the need for sustainable alternatives in animal husbandry. This study explores the potential of natural feed additives as a viable solution to enhance poultry growth and health while reducing reliance on antibiotics. Chinese herbal medicines and probiotics have been widely studied as green, healthy, and safe antibiotic alternatives in livestock and poultry production. A total of 120 chickens were randomly divided into four groups: a control group and three treatment groups supplemented with 1% Pulsatilla chinensis powder, 3% fresh Acer truncatum, or 1% Clostridium butyricum. The results showed that Pulsatilla chinensis powder significantly increased gamma-glutamylcysteine (p < 0.05), UDP-N-acetylglucosamine (p < 0.05), tyramine (p < 0.01), and leucine (p < 0.05). Acer truncatum notably altered cecal metabolites, including L-tyrosine (p < 0.05), α-ketoisovaleric acid (p < 0.01), myristoleic acid (p < 0.01), glutathione (p < 0.05), and PGA1 (p < 0.05). Clostridium butyricum modified cecal metabolites such as L-glutamine (p < 0.05), riboflavin (p < 0.05), L-Carnitine (p < 0.05), ergocalciferol (p < 0.01), and α-tocotrienol (p < 0.05).","40391378":"ID: 40391378\nTitle: Modulation of the human fecal metabolome - Effect of polyphenols depends on the BMI.\nAbstract: Health effects associated with microbial metabolites are influenced by dietary compounds and other environmental factors. Polyphenols derived from plant-based foods reach the large intestine mostly undigested, where they can interact with the gut microbiota. This explorative study investigated the metabolic responses of gut microbiota to the polyphenols rutin and genistein. Ex vivo anaerobic incubations with pooled fecal samples from volunteers with a BMI <25 (n = 7) and a BMI >40 (n = 7) were analyzed by ESI DI-FT-ICR-MS. Differences in metabolic diversity were observed between the two BMI groups, with the obese group showing a less diverse metabolic response. Metabolomic profiling identified 361 metabolites in 35 substance classes, with notable effects of the polyphenols on amino acid, carbohydrate, nucleotide, and lipid metabolism. Both BMI groups showed increased levels of dipeptides and amino acids and decreased levels of biogenic amines. Among the key findings, glutamine levels increased, which has been associated with obesity-related metabolic processes, while tryptophan levels were also elevated, a factor previously associated with obesity-related pathways. Glycine levels increased in both groups. Additionally, histamine, cadaverine, putrescine, and trimethylamine were reduced after exposure to the polyphenols. Changes in metabolites related to carbohydrate metabolism suggest an influence of rutin and genistein on sugar transport and cell wall synthesis. Furthermore, in the obese group, rutin exposure was associated with increased butyrate levels and decreased lactate levels. These findings contribute to a better understanding of how rutin and genistein interact with the gut microbiota metabolome, with potential implications for metabolic health and obesity-related research.","40394473":"ID: 40394473\nTitle: Modulating autism spectrum disorder pathophysiology using a trace amine-focused approach: targeting the gut.\nAbstract: Autism spectrum disorder (ASD) affects approximately 1% of the population directly, but also a much higher proportion (family and caregivers) indirectly. Although ASD is characterized by high prevalence of anxiety and poor gastrointestinal health, current treatment strategies are mainly focused on neurological symptomatic treatment, with little to no attention to gut health. Furthermore, many psychiatric drugs used for management of secondary neurological symptoms, are known to exacerbate gut health issues and neurological dysregulation across the gut-brain axis.Trace amines are neurotransmitter-like substances synthesized endogenously in the human brain - in trace amounts - but also in high abundance by the microbiome. Emerging evidence suggests dysregulation of the trace amine system in ASD. Since trace aminergic signalling is central to regulatory system homeostasis, we hypothesize targeting this system in the ASD context. Given the various sources of trace amines, we suggest that normalization of functional dysbiosis in terms of trace aminergic signalling - rather than microbial compositional dysbiosis - should be a focus in medicines development. In addition, a holistic consideration including also other factors at play in determining trace aminergic signalling outcome - such as receptor binding, enzymatic role players, etc. - is required to fully elucidate and therapeutically modify the pathophysiology of regulatory systems implicated in ASD.This review firstly provides a brief overview of trace amine dysregulation in ASD for context. Secondly, we formulate our hypothesis on how this may therapeutically address symptomology, with consideration of cellular and molecular mechanism interplay across the gut-brain axis. Finally, we provide a critical assessment of advances in therapeutics development and drug re-purposing, gaps in knowledge and priorities for medicines development going forward.","40451401":"ID: 40451401\nTitle: Gut microbe-derived aromatic trace amines mediate individual variability in response to herbal medicine CDD-2101 for functional constipation.\nAbstract: Functional constipation (FC), a common gastrointestinal disorder, poses significant therapeutic challenges due to the limited efficacy and durability of current therapies. A novel strategy for addressing FC involves the targeting of gut dysbiosis. Our previous study demonstrated that the botanical drug CDD-2101 alleviated bowel movement disorders in FC patients. Nevertheless, whether the alterations in gut microbiota composition affected by CDD-2101 are associated with improved bowel movements and the gut microbiota-mediated mechanisms of action of CDD-2101 are not yet fully comprehended. Here, we showed that CDD-2101 enriched aromatic trace amines and aromatic trace amines-producing gut bacteria in FC patients, which correlated with enhanced bowel function and increased peripheral serotonin levels. In preclinical studies, treatment with tyramine, one of the aromatic trace amines, improved constipation-like symptoms and upregulated serotonin production in mice. Consistent with these findings, the colonization of mice with tyramine-enriched fecal microbiota from CDD-2101-treated patients or administration of an aromatic trace amines-producing engineered Lactobacillus casei alleviated constipation-like symptoms and enhanced serotonin production. Mechanistically, we showed that aromatic trace amines improved gastrointestinal motility by activating the trace amine-associated receptor 1 (TAAR1)-serotonin biosynthesis axis. Our study provides mechanistic and therapeutic insights into aromatic trace amines as microbial-derived TAAR1 ligands that regulate serotonin production to improve defecation in FC. These results not only support the therapeutic potential of targeting gut microbiota for the treatment of FC but also identify the aromatic trace amines-serotonin axis, as promoted by CDD-2101, as a pivotal therapeutic target for the improvement of FC.

A total of 1512 female turkeys (B.U.T. 6) were divided into two groups (9 replicate pens) fed either a basal diet (CON group) or CON diet with 5% BSF meal from 65 days to slaughtering (105 days; INS group). The administration of BSF meal improved final body weight (10.17 vs. 10.06 kg/bird, respectively for INS and CON; P = 0.04) as well as daily weight gain and feed conversion ratio in the rearing cycle (96.22 vs. 95.23 g/bird/day and 2.127 vs. 2.141, respectively; P = 0.03). Breast meat quality traits and cecal microbiota were only slightly affected by the treatment. The cecal concentration of tyramine was significantly lower in INS turkeys, which showed higher levels of glucose and malonate (P = 0.03). The use of BSF meal tended (0.05 < P < 0.10) to increase the cecal content of isoleucine, betaine and butyrate, and to reduce the amount of 3-phenylpropionate. Overall, the dietary inclusion of 5% BSF meal from 65 to 105 days improved the growth performances of female turkeys mainly through the modulation of the gut metabolomics profile.","40646988":"ID: 40646988\nTitle: Integrated Microbiome and Metabolomics Insights into Meat Quality Changes in Rice-Field Eel Slices During Refrigeration Storage: Effects of ε-Polylysine, Vitamin C, Epigallocatechin Gallate, and Phloretin.\nAbstract: Rice-field eel (Monopterus albus) slices, an important aquatic product in Southeast Asia, are prone to spoilage and deterioration during cold chain storage. In this study, the effects of a composite preservative (ε-polylysine, Vitamin C (Vc), epigallocatechin gallate (EGCG), and phloretin) on the muscle quality (color, texture, water holding capacity (WHC)) of rice-field eel slices during refrigeration storage at 4 °C for up to 7 days was investigated, and the underlying mechanism was elucidated by the integrated microbiome and metabolomics, in addition to Elisa and Low-Field Nuclear Magnetic Resonance (LF-NMR). After 7 days of storage, the WHC, shear force, and a* decreased by 11.39%, 34.37%, and 49.20% in treated samples, and by 19.18%, 38.38%, and 54.87% in control samples, respectively. The addition of the composite preservative significantly increased Hexokinase, Pyruvate kinase, and Creatine kinase, while it decreased the total viable count (TVC), total volatile basic nitrogen (TVB-N), thiobarbituric acid reactive substance (TBARS), and Lactic acid. Preservative treatment maintained the moisture content of the eel slices during storage and prevented bright red oxymyoglobin from transforming into brown metmyoglobin. Microbiota composition (especially Pseudomonas) and metabolic pathways (including amino acid and its metabolites, nucleotide and its metabolite, and organic acid and its derivatives, etc.) were obviously altered by the preservative treatment. Pseudomonas, tryptophan-aspartic acid (Trp-Asp), D-Glucose 6-phosphate, Succinic Acid, Biliverdin 1, 5-Diaminopentane, and Tyramine, etc., are potential biomarkers for the quality changes of eel slices during refrigeration. These findings provide an in-depth understanding of the improvement of the eel slice quality during refrigeration storage by the composite preservative.","40647126":"ID: 40647126\nTitle: Apple Juice Fermented with Lactiplantibacillus plantarum Improves Its Flavor Profile and Probiotic Potential.\nAbstract: Fermented apple juice (FAJ), a nutrient-dense beverage rich in vitamins, offers multiple health benefits, including improved digestion, enhanced fat metabolism, and sustained energy provision with reduced caloric intake. To advance the development of probiotic-enriched flavored and functional juices, this study establishes Lactiplantibacillus plantarum (L. plantarum) as a safe and effective starter culture for apple juice fermentation. The selected strain exhibited minimal biogenic amine synthesis, producing only 30.55 ± 1.2 mg/L of putrescine and 0.59 ± 0.55 mg/L of cadaverine, while histamine and tyramine were undetectable. Furthermore, the strain demonstrated no hemolytic activity and exhibited robust biofilm-forming capacity, reinforcing its suitability for fermentation applications. An electronic nose analysis revealed that L. plantarum significantly enriched the volatile compound profile of FAJ, leading to an improved flavor profile. The strain also displayed excellent growth adaptability in the apple juice matrix, further optimizing fermentation efficiency and sensory quality. Crucially, 16S rRNA sequencing demonstrated that FAJ specifically restructures the gut microbiota in obese individuals, significantly elevating the relative abundance of beneficial genera, including Enterococcus, Parabacteroides, and Bifidobacterium (p < 0.05). Concurrently, FAJ enhanced glycolytic activity, suggesting a potential role in metabolic regulation. Collectively, these findings confirm that L. plantarum-fermented FAJ combines favorable sensory properties and safety with promising anti-obesity effects mediated through gut microbiome modulation and metabolic pathway activation. This study provides a critical scientific foundation for designing next-generation functional fermented beverages with targeted health benefits.","40838741":"ID: 40838741\nTitle: Serotonergic and immunomodulatory properties of the psychobiotic candidate Bacteroides finegoldii UO.H1052 and its extracellular vesicles.\nAbstract: Bacteroides finegoldii UO.H1052, a human gut commensal, was evaluated for its potential psychobiotic and immunomodulatory properties. Whole-genome analysis confirmed the absence of virulence factors, plasmids, and antibiotic-resistance genes. Metabolomic profiling of cell-free supernatants (CFSs) and extracellular vesicle (EV) postbiotics revealed a high- and medium-dependent production of neuroactive metabolites, including γ-aminobutyric acid, tryptophan, tyrosine, and tyramine, as well as physiologically relevant levels of short-chain fatty acids, such as acetate, propionate, and butyrate. Functionally, CFS enhanced epithelial barrier integrity by increasing transepithelial electrical resistance and mitigating LPS-induced disruption in Caco2/HT29 monolayers without cytotoxic effects. Both CFS and EVs exhibited immunomodulatory properties, characterized by elevated Il-10/Tnf-α ratios under basal conditions and significant suppression of Tnf-α expression in LPS-stimulated RAW 264.7 macrophages. Notably, CFS and EVs increased tryptophan hydroxylase 1 (Tph1) gene expression in enterochromaffin RIN14B cells by 6.6- and 3.2-fold, respectively, suggesting enhanced serotonergic activity. These findings highlight B. finegoldii UO.H1052 as a promising next-generation psychobiotic candidate with neuroactive, barrier-protective, and immunoregulatory properties, supporting its potential for gut-brain axis modulation. Emerging evidence supports the critical role of the gut microbiota in modulating host neurophysiology and immune function via the gut-brain axis. Here, we present a comprehensive characterization of Bacteroides finegoldii UO.H1052, a human gut commensal that exhibits promising psychobiotic attributes, including the production of neuroactive compounds and extracellular vesicles (EVs) with immunoregulatory and serotonin-inducing properties. The strain exhibits a favorable safety profile, with no detected virulence factors or transmissible antibiotic resistance. Importantly, cell-free supernatants and EVs enhanced epithelial barrier integrity, modulated pro- and anti-inflammatory cytokine responses, and significantly upregulated the expression of Tph1, a key enzyme in serotonin biosynthesis. These findings underscore the potential of B. finegoldii UO.H1052 as a next-generation psychobiotic candidate and highlight EVs as effective postbiotic mediators of host-microbe communication. This study advances the understanding of Bacteroides-derived psychobiotics and provides a foundation for their development in modulating gut-brain and immune pathways relevant to neuroinflammatory and gastrointestinal disorders.","40920667":"ID: 40920667\nTitle: Effects of yeast beta-1,3/1,6-glucans on nutrient digestibility, intestinal functionality, and immune and antioxidant variables in growing dogs submitted to spay or neutering surgery.\nAbstract: This study aimed to assess the impact of yeast beta-1,3/1,6-glucans (BG) on apparent digestibility coefficients (ADC) of nutrients, intestinal fermentative metabolites, fecal microbiota profile, and immune and antioxidant variables in puppies before and after surgical challenge. Two treatments were evaluated: control, without, and test, with oral supplementation of 65 mg/kg body weight/day of purified BG from Saccharomyces cerevisiae for 120 days. For this, 16 growing Beagle dogs were distributed in a completely randomized design (n = 8/treatment). On day 31, dogs were submitted to spay or neutering surgery. Diet ADC and fecal characteristics analyses were performed on days 55-60. Fecal (days 0, 15, 30, 34, and 60) and blood (days 0, 30, 34, and 60) samples were collected to evaluate intestinal fermentative metabolites, fecal IgA and microbiota, intestinal permeability, and immune and antioxidant variables. On day 80, all dogs were vaccinated for rabies and blood samples were collected on day 120 to determine antibody titers. The supplementation of BG promoted an increase in fecal IgA concentrations on day 15 (P < 0.05) and an increase in fecal concentrations of butyrate (P < 0.05) when day 30 minus day 0 were compared. Dogs of the BG group presented higher fecal concentrations of serotonin (day 15), spermidine (days 15, 30, and 34), and a reduction in tyramine, histamine, and cadaverine on day 60 (P < 0.001). BG consumption promoted an increase in richness and a clear differentiation in the fecal microbiota profile on days 34 and 60 (P < 0.05). BG group also presented an increase in fecal Faecalibacterium, Blautia, and Turicibacter on day 34 (P < 0.05). Reduced glutathione and catalase activities were higher in the BG group (P < 0.05), regardless of the day. In conclusion, the supplementation of BG does not alter the ADC of nutrients, beneficially modulates the intestinal functionality, and stimulates the activity of antioxidant enzymes in growing dogs submitted to a surgical challenge.","41036868":"ID: 41036868\nTitle: Microbiota-derived aromatic amino acid decarboxylases: linking microbial fitness and host neurochemical communication.\nAbstract: The human microbiota produces a diverse array of bioactive molecules, including classic neurotransmitters (dopamine and serotonin) and trace amines (tryptamine, tyramine, and phenylethylamine). Although long considered products of host metabolism, these aromatic monoamines are now also known to originate in part from the microbiota, where they are synthesized by bacterial aromatic L-amino acid decarboxylases (AADCs). This review explores the distribution, biochemical diversity, and host interactions of microbiota-encoded AADCs, highlighting their roles in gut and skin ecosystems. Bacterial AADCs vary in gene organization, substrate range, and expression patterns across taxa like Ruminococcus gnavus, Clostridium sporogenes, Enterococcus spp., and Staphylococcus spp. These enzymes contribute to microbial fitness through acid stress resistance, energy generation via proton motive force, epithelial adherence and internalization, and niche dominance. Critically, their products modulate host physiology via trace amine-associated receptors (TAARs) and other signaling pathways, influencing neurotransmission, immune response, barrier integrity, and metabolism. Microbiota-derived monoamines can enter systemic circulation and cross the blood-brain barrier, implicating them in disorders ranging from irritable bowel syndrome to neurodegeneration. Emerging data also reveal their impact on wound healing and drug efficacy, notably in Parkinson's disease. By positioning microbial AADCs as key players in host-microbe chemical communication, this review underscores their relevance for health and disease and highlights them as potential therapeutic targets.","41154100":"ID: 41154100\nTitle: Doenjang (Traditional Korean Fermented Soy Paste) Attenuates Development of Colitis-Associated Colorectal Cancer by Modulating Apoptotic, Inflammatory, and Gut Microbiota Pathways.\nAbstract: Colitis-associated colorectal cancer (CAC) is a type of colorectal cancer (CRC) that develops as a result of chronic inflammation, particularly in patients with inflammatory bowel diseases such as ulcerative colitis and Crohn's disease. Persistent intestinal inflammation and dysbiosis of gut microbiota under these conditions are major contributors to CRC progression. Doenjang, a traditional Korean fermented soybean paste, contains probiotics that influence intestinal microbiota composition, as well as biogenic amines (BAs), harmful compounds generated during fermentation. We analyzed the bacterial composition and BA content of Doenjang and evaluated its effects on CAC in a mouse model of AOM/DSS-induced CAC. Results revealed that Doenjang contains diverse beneficial probiotics alongside BAs. Doenjang significantly reduced tumor formation and attenuated CAC progression by modulating inflammatory and apoptotic pathways and suppressed the expression of pro-inflammatory cytokines (TNF-α, IL-1β, and IL-6) by inhibiting the NF-κB pathway. Additionally, Doenjang restored intestinal epithelial barrier integrity by increasing the expression of mucin-related genes (MUC-2, MUC-3) and protective factors like TFF-3. Gut microbiota analysis revealed that Doenjang promoted a healthier gut environment by increasing microbial diversity and reducing inflammation-related bacterial populations. These findings suggest that Doenjang helps prevent and manage CAC by modulating inflammatory responses and gut microbiota composition.","41191059":"ID: 41191059\nTitle: Whole genome sequencing to assess the safety and probiotic potential of Pediococcus pentosaceus L1 isolated from pickled radish.\nAbstract: This research aimed for the safety and probiotic potential assessment of Pediococcus pentosaceus L1, isolated from pickled radish, through its whole genome sequencing analysis and in vitro evaluation. The genome size of Ped. pentosaceus L1 was 1,751,467 bp long with an average guanine-cytosine (GC) ratio of 37.41% and contained 1739 genes in the coding region. The functional annotation of the L1 strain demonstrated that it exhibited excellent probiotic potential and health-promoting properties, with numerous genes linked to the carbohydrate metabolism system, stress resistance, and environmental adaptation. The analysis of virulence factor and antimicrobial resistance indicated the absence of any virulence-related or antibiotic resistance genes in Ped. pentosaceus L1, adding value to its safety profile. In vitro experiments showed that Ped. pentosaceus L1 presented high cell surface hydrophobicity, strong antioxidant activity, no hemolytic activity, and did not synthesize biogenic amines including cadaverine, putrescine, or agmatine. Additionally, its auto- and co-aggregation survival rates indicated its probiotic potential. Ped. pentosaceus L1 also exhibited exceptional exopolysaccharide (EPS) production potential, achieving an enhanced EPS yield in a glucose-supplemented medium. Together, all these characteristics make Ped. pentosaceus L1 an optimistically safe choice for use as a potential probiotic.","41254537":"ID: 41254537\nTitle: Biotechnological potential and genomic analysis of the Leuconostoc mesenteroides F17 and F18 strains isolated from camel milk.\nAbstract: Camel milk is known for its distinctive nutritional and antimicrobial properties. Thus, it offers a valuable niche for discovering novel probiotic strains with potential health benefits. In this context, two Leuconostoc mesenteroides strains, F17 and F18 were isolated from this dairy matrix and their properties analysed. Also, to gain deeper insight into their probiotic and technological traits, the sequencing of the whole genomes of both strains was conducted, revealing key genetic features supporting their suitability as starter cultures. The two bacteria displayed desirable technological properties including among them rapid milk acidification capability as well as proteolytic and lipolytic activities. F17 and F18 produced riboflavin (0.11 and 0.15 mg/L) and exopolysaccharides (1.8 g/L and 3.7 g/L) characterized as dextran by physicochemical analysis. The F17 and F18 DsrD dextransucrases of ~ 170 kDa, responsible for the dextran synthesis, were visualized by a zymogram analysis and their dsrD coding genes, with 98.99% identity, were identified in their genomes. After 24 h growth in a sucrose-containing medium, analysis of metabolic fluxes in culture supernatants of both bacteria demonstrated accumulation of the sweetener mannitol and the antimicrobial lactic acid; at the levels of 59 mM and 76.57 mM in the case of the best performer (F18). Furthermore, the results demonstrated that both strains exhibited good survival rates under in vitro simulated stomach duodenum-passage. A high surface adhesion was also observed for F17 and F18 including hydrophobicity of 30.15% and 31.72% and auto-aggregation ability of 44.71% and 53.23%, with a good resistance to phenol exposure and to moderated heat shock. As expected from the genomes inspection, the safety analysis revealed that the two strains were susceptible to most of the tested antibiotics, and none of them showed any hemolytic activity or biogenic amines synthesis capability. Both cultures supernatants exhibited significant growth inhibition of foodborne pathogens, presumably due to the present of lactic acid. Thus, these findings suggest that camel milk may harbor lactic acid bacteria with promising technological and probiotic traits, as exemplified by F17 and F18.","41286532":"ID: 41286532\nTitle: Low-temperature two-stage probiotic fermentation enhances nutrition and safety of pig liquid feed.\nAbstract: Antinutritional factors present in complete feeds markedly diminish digestive and absorptive efficiency in animals, thereby affecting growth performance and resulting in economic losses. Liquid fermentation technology has been demonstrated to be an effective method of reducing antinutritional factors and enhancing the nutritional value of complete feeds. However, there is a lack of systematic research on the liquid fermentation and the screening of bacterial strains for use. In the present study, Bacillus subtilis and Lactobacillus plantarum characterized by excellent low-temperature tolerance, great enzyme activity, strong bacteriostatic capacity, and exceptional acid production, were evaluated for their suitability in a two-stage (aerobic followed by anaerobic) liquid fermentation process of complete pig feed. The results demonstrated that soybean antigenic protein and crude fiber underwent significant degradation, while crude protein and acid-soluble protein content exhibited significant increases in the feed following two-stage fermentation. Additionally, the accumulation of biogenic amines was inhibited to ensure the palatability of the feed. Furthermore, two-stage fermentation significantly enhanced the antioxidant and enzymatic activity of the feed. High-throughput 16S rRNA sequencing revealed an increased relative abundance of beneficial bacteria and a decreased abundance of pathogenic bacteria after fermentation. This study corroborated that a two-stage fermentation process could enhance the nutritional value, safety, and probiotic functionality of animal feeds. This finding provides a theoretical foundation for the development of functional fermented feeds and provides the necessary technical support for the practical application of liquid fermentation feeds. KEY POINTS: • Developed a novel low-temperature two-stage liquid fermentation feed strategy using Bacillus subtilis 3-16 and Lactobacillus plantarum E5 • Significantly degraded antinutritional factors and biogenic amines, while increasing the crude protein, acid-soluble protein, enzymatic activity, and antioxidant capacity of complete pig feed • Promoted beneficial microbiota dominance (e.g., Lactobacillus plantarum and Bacillus subtilis, while reducing pathogenic bacteria (e.g., Escherichia coli and Staphylococcus aureus).","41293416":"ID: 41293416\nTitle: Safety evaluation of Lacticaseibacillus rhamnosus KF7 based on complete genome, phenotypic assays and alternative models: Caenorhabditis elegans.\nAbstract: This study evaluated the safety of Lacticaseibacillus rhamnosus (L. rhamnosus) KF7, a probiotic strain originating from kefir, for potential use in infant and children's food products in China. The safety evaluation was conducted through a comprehensive approach involving whole-genome sequencing, in vitro and in vivo studies using alternative models: Caenorhabditis elegans (nematodes). Genomic analysis confirmed the absence of virulence factors and antibiotic resistance genes in KF7. Phenotypic characterization demonstrated that KF7 exhibits no antibiotic resistance, does not produce indole, is non-hemolytic, and lacks amino acid decarboxylase activity. Furthermore, KF7 was found to not produce histamine and generate only a minimal amount of tyramine when cultured in MRS medium supplemented with amino acids. The strain was also shown to produce both L- and D-lactic acid, with the concentration of D-lactic acid falling within a safe range. To further evaluate the safety of KF7 in vivo, nematode model was employed, with Pseudomonas aeruginosa serving as a pathogenic control and L. rhamnosus GG, known to be safe for infants and children, as a positive control. The results demonstrated that KF7 does not adversely affect nematode egg-laying, egg development, growth, locomotion, or lifespan. Instead, it appeared to have beneficial effects on gut microbiota and extending the nematodes' lifespan. In summary, this study established the method of using nematode as an in vivo evaluation to the safety of probiotics, and the safety data of the KF7 strain was supplemented by in vitro research, which proved that KF7 has a certain degree of safety.","41299593":"ID: 41299593\nTitle: Gut microbial tyramine facilitates intestinal damage and metabolic dysfunction-associated steatotic liver disease development.\nAbstract: Emerging evidence indicates that gut microbiota and intestinal injury are crucial in pediatric metabolic dysfunction-associated steatotic liver disease (MASLD), yet the role of key gut microbial metabolites such as tyramine in pediatric MASLD remains largely unknown. In this study, we aimed to explore the role of gut microbial tyramine in intestinal damage and MASLD development in children. We investigated the functions and mechanisms of previously isolated Enterococcus faecium B6 (E. faecium B6) and its derived tyramine in a mice model of intestinal injury and MASLD development. An integrative analysis of transcriptomics and proteomics was performed on mouse liver to explore the molecular mechanisms of tyramine in MASLD progression. Targeted metabolomics was performed using fecal samples from a hospital-based population (27 MASLD cases and 27 matched controls) to measure tyramine levels. The association of serum tyramine and MASLD risk was then validated in a school-based population, using serum samples of 294 children in the MASLD group and 235 controls. E. faecium B6 and its metabolite tyramine significantly disrupted the intestinal barrier and increased intestinal permeability in mice. Tyramine supplementation promoted MASLD-related metabolic phenotype in mice. Multi-omics analysis indicated that the PPAR signaling pathway played an important role in the molecular mechanisms. Tyramine contributed to lipid accumulation mainly by increasing lipid synthesis and lipid uptake but reducing the β-oxidation processes in the mouse liver, as shown by real-time quantitative polymerase chain reaction and western blot. Furthermore, we demonstrated from the hospital-based cohort that tyramine concentration was significantly higher in the MASLD group than in the control group. Consistently, the school-based cohort demonstrated a higher risk of MASLD in the high-tyramine group compared to the low-tyramine group, with adjusted odds ratios (ORs) and 95% confidence intervals (CIs) of 3.65 (95% CI: 2.66-4.32). These results demonstrated that gut microbial tyramine effectively induced intestinal damage and facilitated MASLD development in mice. Tyramine was positively associated with the risk of MASLD in children. This study offered mechanistic insights into the pathogenesis of MASLD and opened therapeutic opportunities for such metabolic diseases.","41330669":"ID: 41330669\nTitle: Split biosensor based on nano-enzymatic ferrocene-tyramine deposition reaction for detection of SMP30 antibody.\nAbstract: The tumor-associated autoantibody against senescence marker protein-30 (SMP30) serves as a critical serum biomarker for the early detection of hepatocellular carcinoma (HCC), enabling rapid and non-invasive cancer diagnosis and monitoring. However, the accurate detection of the SMP30 antibody remains challenging due to the complex composition of blood and the heterogeneity of circulating antibodies. This study introduces a highly sensitive and straightforward method for SMP30 antibody detection, utilizing a graphene oxide-Hemin (GO-Hemin) composite nano-mimetic enzyme in combination with ferrocenyl-tyramine (Fc-Tyr)-mediated tyramine signal amplification (TSA) within microtiter wells. A solid-phase protein with high affinity selectively captures the SMP30 antibody, while the target is identified via nano-mimetic enzyme labeling of a secondary antibody. The subsequent nano-enzymatic reaction facilitates the deposition of Fc-Tyr, generating a strong electrochemical signal. The biosensor achieves high sensitivity through enhanced electrochemical transduction and minimal spatial resistance at the electrode interface. By integrating immunocapture specificity with electrochemical amplification, this approach enables high-throughput analysis in clinical applications. Experimental results demonstrate that this biosensor can detect smp30 antibodies at concentrations as low as 0.1086 ng/mL, with a detection range spanning 0.1 ng/mL to 1 μg/mL. Analysis of authentic serum samples confirmed that when combined with ELISA, the sensor accurately measured SMP30 antibody levels in serum samples from clinical hepatocellular carcinoma patients. The results demonstrated consistent detection outcomes with recovery rates ranging from 93 % to 104 % and relative standard deviations (RSD) between 1.2 % and 3.7 %. This platform provides a practical and efficient tool for detecting SMP30 antibodies and holds broader application potential in tumor marker monitoring and cancer diagnosis.","41364165":"ID: 41364165\nTitle: Role of brain-gut axis in mechanism of gastrointestinal defense.\nAbstract: The digestive system, comprising gastrointestinal (GI)-tract and connecting organs, such as liver or pancreas, has a wide autonomy in the human body due to the presence of specific nervous and endocrine systems of its own and can act voluntarily without stimulation from the rest of the body. This wide physiological autonomy of a digestive tract does not exclude connection with other organs and central as well as peripheral mechanisms controlling nervous and hormonal systems. The vagal nerve is a structure connecting GI-tract with brain centers. Both, the afferent and efferent components of the vagal nerve innervate the GI-tract and modify its functions. An example of stimulants affecting afferent fibers of vagal nerve are digestive hormones, such as cholecystokinin (CCK), because CCK is commonly recognized as the gut hormone that stimulates specific receptors located at the endings of vagal afferent fibers and promotes the vago-vagal reflex. Recent studies have documented that GI-tract is a source of abundant hormones regulating the hunger - satiety centers in the hypothalamus via afferent fibers of the vagal nerve, forming the brain-gut axis. In addition, local endocrine cells in the GI-tract can produce biogenic amines, such as serotonin or histamine which also can stimulate afferent component of this axis. The complexity of brain - gut axis is augmented by the participation of other factors, that can influence it, such as metabolites of gut microbiota, changes in the intestinal permeability, the proinflammatory cytokines and other immune responses, activity of the stress hormones, such as adrenaline, cortisol and aldosterone. In addition, the presence of the short chain fatty acids (SCFA) can modify the bidirectional brain-gut and gut-brain axes activity, indirectly, as nutrients for specific bacterial species, or directly, by stimulation of the specific receptors located within the GI wall. In this review, we focused on the brain-gut axis is involved in the strenghtening of the mucosal barrier via maintaining of oxidative balance. The main process reaction causing cellular destruction is lipid peroxidation. Lipid peroxides disrupt the structure of cellular lipids, making this barrier more permeable. Increased cellular permeability of GI-tract barrier contributes to the stimulation of the brain-gut axis. Pharmacological agents, affecting mucosal blood flow, such as cyclooxygenase (COX) products, COX inhibitors and pentoxifylline, are also able to modify functions of the brain-gut axis. We conclude that brain-gut axis plays a particularly important role in maintaining of mucosal barrier in GI-tract and alteration in its functions is implicated in pathogenesis of various diseases of the gut.","41369149":"ID: 41369149\nTitle: Bioavailability and Metabolism of N-Trans Caffeoyltyramine and N-Trans Feruloyltyramine - A Narrative Review.\nAbstract: Insights into the bioavailability of hemp derived phenolic amides N-trans caffeoyltyramine (NCT) and N-trans feruloyltyramine (NFT) remained limited to experimental data from preclinical in vitro and animal systems. However, the bioavailability of similar phenolics and phenolic amides from other sources has been experimentally determined. This concise review summarizes the current state of knowledge for phenolic amides with the goal of providing experimental guidance on the assessment of NCT and NFT from hemp ingredients in humans. Evidence from phenolic and avenanthramide (similar phenolic amides from oats) suggest that overall absorption of free phenolic amides would be limited in humans to <2% of native forms. Metabolites derived by both host (conjugated Phase II metabolites) and microbial fermentation products would likely represent the main compounds in circulation derived from NCT or NFT intake. This would be extensively influenced by the matrix provided including hemp-based ingredients with large portions of physically and chemically bound NCT and NFT forms that are not absorbable. Experimental designs to determine NCT and NFT response in humans would need to consider longer exposure and collection periods to adequately capture 24 and 48h urine and blood samples likely to have key NCT and NFT derived microbial and host metabolites present. Considering adaptation of the microbiota to these compounds it is likely that a robust design would also include a dimension of long-term exposure to enable detection of target metabolites derived from hemp NCT and NFT.","41370292":"ID: 41370292\nTitle: Caste- and age-specific venom composition of biogenic amines and the influence of diet in honey bees.\nAbstract: The chemical composition of the venom in social Hymenoptera differs between castes and ages. Biogenic amines are contained in the venom of honey bees and may be physiologically effective to vertebrate predators and insects. This study quantified the concentrations of biogenic amines in venom and compared them between different castes and ages of honey bees. The concentrations of dopamine and N-acetyldopamine in venom were significantly higher in virgin queens than workers of the same age. The concentrations of dopamine, norepinephrine, tyramine and serotonin increased with age in virgin queens and workers. There was a significant positive correlation between venom dopamine concentrations and ovarian development in queenless workers, suggesting that the concentration of dopamine in the venom transformed from normal workers to reproductive females as that in virgin queens. We also tested the possibility of dietary effects on the concentration of dopamine in venom. Workers fed tyrosine or royal jelly showed significantly higher concentrations of dopamine precursors, tyrosine, 3,4-dihydroxyphenylalanine (DOPA) and dopamine in the hemolymph, as well as higher concentrations of dopamine in venom than in controlled workers. These results suggest that compositions of biogenic amines in venom are influenced by nutrition and change based on their social roles in honey bee society.","41421311":"ID: 41421311\nTitle: Orange corn diet modulates Pekin duck cecal neurochemistry under normal and heat stress conditions.\nAbstract: Heat stress (HS) drives changes in poultry gut health that negatively affect performance, behavior, foodborne pathogen carriage, among other factors. Little attention, however, has been directed towards the impact of HS on the duck intestinal tract. Intestinal concentrations of monoamine neurochemicals, which have been shown to be stress-responsive in several poultry species, play a variety of roles in mediating the effects of stress both locally in the gut and in overall physiology. Yet, the concentrations of neurochemicals and accompanying metabolic pathways in the duck intestine remain understudied. As an orange corn (OC) diet was previously shown in poultry to benefit welfare and performance, the present study sought to determine the impact of an OC versus a yellow corn (YC) diet on duck intestinal monoamine neurochemistry under thermoneutral and heat stress conditions. Male and female Pekin ducks were randomly assigned to a YC or OC diet, with each diet fed for 3 wks immediately before HS, and then continuing being fed during the 3 wks of cyclic HS exposure (35°C for 10h/d). Cecal tissue (CT) and luminal content (CC) were collected before the start of HS and then on the final day of the 3 wks of HS. Sex and feed type affected (p < 0.05) catecholamine and serotonin concentrations in ducks under thermoneutral and HS conditions. CT protein expression of monoamine oxidase-A and catechol-o-methyltransferase showed sex- and feed type-dependent changes (p < 0.05) only in ducks that underwent HS. DOPA-decarboxylase was affected (p < 0.05) under HS but not during constitutive conditions. The present study establishes that the duck intestinal tract is an abundant source of monoamine neurochemicals, and that key proteins involved in neurochemical metabolism are present in the duck ceca. These findings warrant the study of feed components as a tailorable strategy to potentially control stress at the gut-level. As enteric neurochemicals play critical roles in inflammation, foodborne pathogen colonization, and other production-relevant aspects in poultry, our findings highlight the importance of intestinal neurophysiology in the duck.","41429111":"ID: 41429111\nTitle: A therapeutic gastrointestinal diet improves nutrient digestibility and modulates fecal microbiota and metabolites in dogs.\nAbstract: To evaluate the effects of a therapeutic gastrointestinal diet on the apparent digestibility coefficients (ADCs), metabolizable energy (ME), and palatability of the diet, fermentative metabolites, and fecal microbiome of dogs. Sixteen 1-year-old healthy Beagles were used. All animals consumed a control diet for healthy adult dogs for 20 days. On day 21, 8 dogs changed to a therapeutic gastrointestinal diet (test diet), and 8 dogs continued receiving the control diet for 35 days. Fresh feces were collected on days 0, 3, 15, and 30 after changing to the test diet for pH, fermentative metabolites, and microbiota analysis. Feces were collected for ADCs and ME analysis of the diets (days 31 through 35). The palatability of the control and test diets was compared at the end of the study. The test diet presented greater ADCs of nutrients and ME and resulted in lower fecal pH and greater fecal concentrations of ammonia, total biogenic amines, total short-chain fatty acids, and butyrate. β-Diversity analysis revealed distinct fecal microbiome profiles between the diets on days 3, 15, and 30, with a greater abundance of Turicibacter and Faecalibacterium and lower Streptococcus in the test group. Dogs preferred the test to the control diet in the palatability test. The test diet presented high ADCs of nutrients, high palatability, and beneficially modulated the fecal microbiome and fermentative metabolites of dogs. Providing a highly digestible and palatable diet with functional ingredients may contribute to the treatment of gastrointestinal disorders of dogs.","41462699":"ID: 41462699\nTitle: Hepatoprotective, Antioxidant, and Anti-Hyperlipidemic Effects of Kefir Milk in High-Fat Diet-Induced Obesity: Insights from Gas Chromatography-Mass Spectrometry Profiling, Molecular Docking of Kefiran, and Liver Function Restoration.\nAbstract: The prevalence of chronic diseases, including obesity and related endocrine disorders, has risen significantly in recent decades. As a result, there has been growing interest in fermented foods with probiotic properties, such as kefir, which have potential health benefits. This study aimed to evaluate the hepatoprotective and antioxidant effects of kefir milk (KM) in a high-fat diet (HFD)-induced obesity rat model, complemented by in silico molecular docking studies with antioxidant enzymes. Twenty-four adult rats were divided into four groups: control (1 mL/100 g bw semi-skimmed cow milk), KM (1 mL/100 g bw kefir milk), HFD (1 mL/100 g bw semi-skimmed cow milk + high-fat diet), and KM/HFD (1 mL/100 g bw kefir milk + high-fat diet). After 60 days of treatment, biochemical assays and histological examinations were performed to assess the effects on lipid profiles and organ health. Kefir milk demonstrated significant antioxidant activity, with increased total phenolic content and enhanced DPPH, ABTS, and FRAP radical scavenging activities compared to commercial milk. Furthermore, KM administration protected against liver metabolic disruptions (ALT, AST, and LDH) induced by the high-fat diet and reduced lipid peroxidation in liver and testis tissues. KM supplementation also increased the activity of key antioxidant enzymes, including superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx). Additionally, KM improved the fatty acid composition and decreased the de novo lipogenesis (DNL) index, as well as enzyme activities (SCD and Elovl6) associated with the high-fat diet. Histological analysis of liver, pancreas, and heart tissues revealed that kefir milk attenuated structural damage caused by the high-fat diet, suggesting its protective role in oxidative stress regulation and organ function. These findings underscore the potential of kefir milk as a functional food for preventing metabolic disturbances and liver damage associated with obesity.","41462983":"ID: 41462983\nTitle: New Insights into Complex PTSD Treatment: Focus on TAAR1 Agonists.\nAbstract: Background/Objectives: The therapeutic potential of selective trace amine-associated receptor 1 (TAAR1) agonists has been established in multiple animal models of depression and anxiety. PTSD is a debilitating psychiatric disorder frequently characterized by anxiety and often comorbid with major depressive disorder. Complex PTSD represents an even more severe clinical presentation, emerging from prolonged or repeated exposure to traumatic events. Recent studies indicate that TAAR1 agonists can attenuate anxiety-like behaviors in experimental models of PTSD; however, the molecular mechanisms underlying this effect remain poorly understood. In this study, we evaluated whether TAAR1 agonism modulates PTSD-related neurochemical and molecular changes within the hippocampus and striatum. Methods: Post-traumatic stress was modeled using predator stress, a validated experimental paradigm relevant to complex PTSD. Treatment consisted of intraperitoneal administration of the TAAR1 agonist LK00764. Monoamine neurotransmitters and their metabolites were quantified, and the expression of genes implicated in noradrenergic, dopaminergic, and serotonergic signaling pathways was assessed. In addition, gene network reconstruction was performed using artificial intelligence to identify TAAR1-dependent regulatory interactions. Results: Treatment with a TAAR1 agonist fully prevented behavioral abnormalities in the experimental model of complex PTSD. Neurochemical analyses revealed decreased 5-HT levels in the hippocampus and reduced dopamine and metabolite concentrations in the striatum following TAAR1 agonism. Moreover, TAAR1 activation was associated with increased expression of the neurotrophic factor BDNF in the striatum. Gene network reconstruction identified a distinct molecular hub within the PTSD network, comprising TAAR1-coexpressed genes, their encoded proteins, and interconnected signaling pathways, suggesting a tightly regulated feedback loop. Conclusions: These findings provide novel evidence that TAAR1 agonists exert protective effects against complex PTSD-related behavioral and neurochemical abnormalities. The reconstructed TAAR1-centered gene network offers mechanistic insight into receptor-dependent regulation of monoaminergic signaling and neuroplasticity, supporting further exploration of TAAR1 agonists as promising therapeutic candidates for PTSD.","41465348":"ID: 41465348\nTitle: Expression Alterations and Correlative Analysis of TPH1/hsa-miR-194-5p/NEAT1 and MAOA/hsa-miR-1276/NEAT1 Axes in Pediatric Inflammatory Bowel Disease.\nAbstract: Pediatric inflammatory bowel disease (pIBD), comprising ulcerative colitis (UC) and Crohn's disease (CD), involves complex mechanisms that include non-coding RNAs (ncRNAs), such as microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), alongside enzymes regulating serotonin metabolism. Tryptophan hydroxylase 1 (TPH1) and monoamine oxidase A (MAOA) play critical roles in serotonin turnover and may contribute to intestinal inflammation. We investigated the expression of TPH1, MAOA, hsa-miR-194-5p, hsa-miR-1276, and the lncRNA Nuclear Enriched Abundant Transcript 1 (NEAT1) in intestinal tissue biopsies and peripheral blood from pIBD patients and controls. TPH1 was significantly elevated in the inflamed transverse colon (p = 0.034), whereas MAOA was reduced in the ileum (p = 0.041) and descending colon (p = 0.001), with further decreases in inflamed ileum (p < 0.001), ascending (p = 0.008), and descending colon (p = 0.001). Subgroup analysis revealed decreased MAOA in the ascending colon of UC patients (p = 0.011). hsa-miR-194-5p was upregulated in the transverse colon (p = 0.015), inflamed transverse (p = 0.013) and descending colon (p = 0.015), and in blood of UC patients (p = 0.01). NEAT1 expression increased in the ascending colon (p = 0.042) but decreased in the ileum (p = 0.006). Correlation analysis showed strong positive associations between TPH1 and NEAT1 in the ileum (r = 0.945, p < 0.01) and transverse colon (r = 0.609, p < 0.01). These results highlight region-specific dysregulation of serotonin-related genes and ncRNAs in pIBD, with the TPH1/miR-194-5p/NEAT1 axis potentially contributing to disease pathophysiology and warranting further mechanistic investigation.","41488014":"ID: 41488014\nTitle: Efficacy and safety of avatrombopag in aplastic anemia: a comprehensive review of clinical evidence.\nAbstract: Aplastic anemia is a bone marrow failure disorder marked by cytopenias that impair oxygen delivery, immune defense, and hemostasis. Standard therapy traditionally combines immunosuppression with or without hematopoietic stem cell transplantation, and more recently incorporates thrombopoietin receptor agonists to stimulate residual hematopoiesis. Eltrombopag improved outcomes when added to immunosuppressive therapy, but its association with hepatotoxicity limits its suitability for patients with underlying liver disease or elevated baseline liver enzymes. Avatrombopag is a newer oral thrombopoietin receptor agonist that does not require dietary restrictions and does not undergo significant hepatic metabolism, which offers a potential therapeutic advantage in settings where liver function is compromised. This review evaluated ten clinical studies published from 2023 to October 2025 that investigated avatrombopag in acquired aplastic anemia across varied patient populations, including treatment-naive, relapsed or refractory cases, older adults, and patients with secondary aplastic anemia related to chemoradiation. Across these studies, overall response rates ranged from 55% to 85%, and complete response rates reached up to one-third of treated patients. Response onset typically occurred within 1-2 months, which aligns with clinical decision timelines for assessing therapeutic benefit. Avatrombopag supported reductions in transfusion requirements and sustained hematologic improvement in both severe and non-severe disease. Patients previously intolerant or non-responsive to eltrombopag also demonstrated clinical improvement, which suggests pharmacologic differences translate into meaningful therapeutic effects. Importantly, avatrombopag demonstrated a favorable safety profile in all reviewed settings. Reports did not identify clinically relevant hepatotoxicity, clonal evolution, or treatment-limiting adverse effects. Its tolerability in patients with liver dysfunction distinguishes it from earlier agents in this drug class. Ongoing trials will clarify optimal dosing strategies and define its future role within first-line therapy and salvage treatment pathways for aplastic anemia. A new treatment option for aplastic anemia: how avatrombopag may help patients with fewer side effects Aplastic anemia is a rare but serious disease where the bone marrow stops making enough blood cells. People with this condition often feel tired, bruise easily, or get frequent infections. The standard treatment for those who can’t get a bone marrow transplant is a combination of medications that suppress the immune system. Another helpful medicine, eltrombopag, boosts blood cell production but can harm the liver, which limits its use in some patients. Avatrombopag is a newer medicine that also stimulates blood cell production but seems to be safer for the liver. It’s taken as a pill and does not interact with food or most other drugs. This review looked at eight studies from 2023 and 2024 to understand how well avatrombopag works and how safe it is. The studies included patients with different types and severities of aplastic anemia, including older adults and those with liver problems. Overall, more than half of the patients improved with avatrombopag, and some fully recovered. Most people began feeling better within one to two months. Avatrombopag was helpful even for people who didn’t respond to other treatments. It caused few side effects and did not damage the liver. Some patients even had improved liver function during treatment. These results suggest that avatrombopag is a promising new treatment for aplastic anemia. It may offer a better and safer option for patients, especially those who can’t tolerate other drugs. More research is underway to confirm these findings and explore its role in standard treatment plans.","41488142":"ID: 41488142\nTitle: Placental serotonergic system dysregulation is associated with early impairments in infant neurodevelopment.\nAbstract: Serotonin (5-hydroxytryptamine [5-HT]) plays a fundamental role in fetal neurodevelopment. While 5-HT is synthesized in the fetal brain, the placenta contributes significantly to fetal 5-HT levels during early gestation. However, little is known about the influence of placental serotonergic components on early neurodevelopmental outcomes. In this study, we have evaluated the association between the expression of key components of the placental serotonergic system and neurodevelopmental status in infants of mother-child dyads enrolled in the Origen Bioquímico y Epigenético del Sobrepeso y la Obesidad (OBESO) perinatal cohort at the first month of life. We analyzed 5-HT concentrations in maternal serum, umbilical cord serum, and placental tissue, and investigated the expression of key proteins of the serotonergic system in the placenta. All samples were obtained from full-term healthy pregnancies. 5-HT levels were measured by ELISA, and protein expression in placental tissue was evaluated by Western blot. Neurodevelopment was assessed at 1 month of age using the Bayley Infant Development Scale III (BSID-III). Infants with two or more BSID-III domain scores ≤ 7 were grouped as having altereded neurodevelopment. Placentas from infants with altered neurodevelopment exhibited higher expression of tryptophan hydroxylase types 1 and 2 (TPH1 and TPH2)-the rate-limiting enzymes in 5-HT synthesis-as well as the serotonin transporter (SERT), compared to those from infants with normal neurodevelopment. In contrast, expression of monoamine oxidase-A (MAO-A), the primary degrading enzyme, was significantly lower in the altered group. Interestingly, 5-HT levels and the expression of 5-HT1E and 5-HTR5A receptors were similar between groups. These findings suggest that dysregulation of the placental serotonergic system, independent of total 5-HT levels, could be associated with early neurodevelopmental impairments, highlighting the importance of placental serotonin signaling in fetal brain development.","41492376":"ID: 41492376\nTitle: Milk fat globule membrane ameliorates depressive-like behaviors in chronic unpredictable mild stress rats by modulating the microbiota-gut-brain axis.\nAbstract: Depression is one of the common psychiatric disorders, and it has been reported that the imbalance in the microbiota-gut-brain (MGB) axis contributes to the pathogenesis of depression. Milk fat globule membrane (MFGM) can impact the gut-brain axis by regulating the intestinal flora and metabolite production. The aim of this study was to investigate whether MFGM could ameliorate depressive-like behaviors induced by chronic unpredictable mild stress (CUMS) and further elucidate the potential mechanism through a fecal microbiota transplantation (FMT) experiment. Male Sprague-Dawley rats were provided with an MFGM diet for 5 weeks after the induction with CUMS. Depressive-like behaviors were assessed, and the levels of neurotransmitters, neuroendocrine hormones, microbiota, short-chain fatty acids (SCFAs), and tight junction proteins, including occludin and zonula occludens-1 (ZO-1), were measured. It was revealed that MFGM could alleviate the depressive-like behaviors in CUMS rats. MFGM up-regulated the expression of occludin and ZO-1 and ameliorated intestine pathological changes in CUMS rats. Moreover, MFGM increased the levels of 5-hydroxytryptamine (5-HT), dopamine (DA), and norepinephrine and decreased the levels of neuroendocrine hormones in CUMS rats. Furthermore, it was confirmed that the concentrations of SCFAs, DA, 5-HT, and tight junction proteins significantly increased in the recipient rats that were inoculated with the fecal microbiota from the rats after MFGM treatment. These findings demonstrated that MFGM could alleviate depressive-like behaviors in CUMS rats and was possibly associated with modulation of the gut microbiota and up-regulation of SCFAs and monoamine neurotransmitters.","41494586":"ID: 41494586\nTitle: Microorganisms and Physicochemical Factors Controlling Biogenic Amines During Cheese Ripening: A Systematic Review.\nAbstract: Biogenic amines are nitrogenous compounds formed by amino acid decarboxylation, and their excessive accumulation in cheese may cause adverse health effects. This systematic review aimed to evaluate the effectiveness of probiotic strains and physicochemical factors in reducing biogenic amine levels during cheese ripening. Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, a comprehensive literature search was conducted in PubMed, Scopus, Web of Science, ScienceDirect, and Google Scholar for studies published between 2010 and 2024. Fourteen studies met the inclusion criteria. Among the identified biogenic amines, tyramine and histamine were most frequently reported at high concentrations. The combination of Lactobacillus acidophilus and Lactiplantibacillus plantarum demonstrated the highest efficacy, achieving up to 80% reduction in total biogenic amine levels. Optimal physicochemical conditions, including maintaining a pH range of 5.0-5.4, a ripening temperature around 15 °C, and a maturation period of 3-4 months, enhanced the efficiency of probiotic interventions. Environmental factors such as salt, moisture, fat content, and packaging methods significantly influenced biogenic amine accumulation. Integrating selected probiotics with controlled ripening parameters can minimize biogenic amine levels and improve cheese safety and quality. However, due to heterogeneity in probiotic strains, cheese types, and analytical techniques among the included studies, further standardized and large-scale investigations are required to better understand the mechanisms and optimize strategies for biogenic amine reduction in cheese production.","41539433":"ID: 41539433\nTitle: Fermented and non-fermented pickles modulate gut microbiota in older adults with dysphagia: A pilot crossover study.\nAbstract: Dysphagia is common among older adults and often leads to dietary restrictions, reduced appetite, malnutrition, and decreased quality of life. Although pickles are widely enjoyed by older adults, dysphagia-friendly pickles are often avoided owing to their texture. Moreover, many dysphagia-friendly foods are non-fermented and lack live lactic acid bacteria, and it remains unclear whether texture-modified, non-fermented pickles can favorably influence the gut microbiota. Therefore, this exploratory, microbiotal-focused study examined preliminary, taxon-level gut microbiotal signals associated with dysphagia-adapted non-fermented versus fermented pickles. In this pilot, single-blind, 2 × 2 crossover study, participants were alternately allocated to receive non-fermented or fermented pickles (finely shredded sauerkraut cut into 1-mm strips) first, with a 2-week washout between periods. Fecal samples were collected before and after each intervention. The gut microbiotal composition was analyzed using 16S rRNA gene amplicon sequencing and bioinformatic processing via QIIME2. Microbial diversity and taxonomic changes were analyzed using Wilcoxon's signed-rank test. Finally, α-diversity (Shannon, Chao1, Simpson), β-diversity (Bray-Curtis permutational multivariate analysis of variance), and taxon-level relative abundances for prespecified taxa (e.g., Bifidobacterium, SCFA-associated taxa) were evaluated. Thirteen participants were enrolled. There were no significant post-intervention changes in α-diversity (e.g., shannon p = 0.273, 0.414) and β-diversity (p = 0.993, 0.999). However, consumption of non-fermented pickles significantly increased the abundance of Actinobacteriota, including Bifidobacteriales, Bifidobacteriaceae, and Bifidobacterium (p = 0.012). In contrast, consumption of fermented pickles significantly increased the abundance of several short-chain fatty acid-associated taxa, including [Eubacterium] coprostanoligenes group and Marvinbryantia genus. Texture-modified pickles and fermented pickles can be safely provided and feasibly consumed by older adults with dysphagia risk. Their consumption induced modest, taxon-specific shifts in gut microbial composition, without altering global diversity. These exploratory pilot findings demonstrate feasibility and suggest taxon-level trends requiring confirmation in larger, randomized trials with functional and clinical endpoints.

By contrast, pythons are ambush predators that exhibit extreme feeding and fasting patterns and provide a unique model for uncovering molecular mediators of the postprandial response 1-3 . Using untargeted metabolomics, here we show that circulating levels of the metabolite para -tyramine-O-sulfate (pTOS) are increased >1,000-fold in pythons after a single meal. In pythons, pTOS production occurs in a microbiome-dependent manner via sequential decarboxylation and sulfation of dietary tyrosine. In both pythons and mice, pTOS administration activates a neural population in the ventromedial hypothalamus (VMH). In mice, these VMH neurons are required for the anorexigenic effects of pTOS. Chronic administration of pTOS to diet-induced obese male mice suppresses food intake and body weight. pTOS is also present in human blood, where its levels are increased after a meal. Together, these data uncover a conserved postprandial anorexigenic metabolite that links nutrient intake to energy balance.","41543761":"ID: 41543761\nTitle: Towards treatments targeting the gut to improve behavioural outcomes in autism spectrum disorder.\nAbstract: Autism spectrum disorder (ASD; autism) is a prevalent and heterogeneous neurodevelopmental disorder characterised by social communication difficulties, repetitive behaviour, and restricted interests. For individuals with autism, in particular those who require substantial care-giver support, irritability, heightened sensitivity and aggressive behaviours in response to sensory, social, or environmental triggers can limit access to health, education and community services and impact quality of life. Although gastrointestinal (GI) symptom severity is associated with irritable behaviours in autism, there are few approved medications to address challenging behaviour or comorbid psychiatric disorders, or gut dysfunction in autism. Here, we review the mode of action of drugs undergoing clinical trials for treating irritable behaviour and improving social communication as well as potentially gastrointestinal symptoms in individuals with autism. Repurposed medications such as pimavanserin (an atypical antipsychotic) and the antiparasitic suramin are being trialled for treating irritable behaviours and impaired social interaction, respectively, in autism. NTI164 is a medicinal cannabis-derived biopharmaceutical undergoing clinical safety and efficacy trials for improving social communication and similarly, ML-004 is an investigational drug being assessed for treating social communication deficits. Two other repurposed medications previously utilised for schizophrenia; brexpiprazole and lumateperone, as well as AB-2004, a microbial metabolite sequestering agent (with proposed actions on gut function), are undergoing clinical trials to assess impacts on irritability associated with autism. We also outline emerging findings from clinical studies on the use of gut-targeted small molecules and bacteriophage therapy, prebiotics, probiotic supplementation and faecal microbiota transplantation (FMT), and their potential impact on behavioural symptoms in autism.","41550498":"ID: 41550498\nTitle: The TAAR1 antagonist EPPTB ameliorates colitis via serotonin inhibition.\nAbstract: Inflammatory bowel disease (IBD) is characterized by gut dysbiosis and impaired microbial metabolite signaling. Emerging evidence suggests that gut microbial metabolites, such as trace amines (tryptamine, phenethylamine, and tyramine), function as endogenous TAAR1 agonists and may contribute to IBD pathogenesis. Our study identified elevated fecal trace amine levels in ulcerative colitis (UC) patients and DSS-induced colitis mice. In vitro, exposure to these trace amines enhanced 5-HT secretion in QGP-1 cells and ex vivo mouse colonic tissues, and this effect could be blocked by the TAAR1 antagonist EPPTB. In vivo, EPPTB treatment significantly mitigated DSS-induced colitis, as demonstrated by reduced weight loss, improved disease activity index (DAI), preserved colon length, and attenuated histopathological damage. Moreover, TAAR1 blockade reduced pro-inflammatory cytokines (TNF-α, IL-6, IL-1β) and increased IκB-α expression, restored intestinal barrier integrity (upregulating occludin and ZO-1, while downregulating cclaudin-2), and lowered colonic 5-HT levels by suppressing TPH1 expression. These findings suggest that TAAR1 inhibition alleviates colitis by modulating 5-HT signaling, positioning it as a promising therapeutic target for IBD.","41552834":"ID: 41552834\nTitle: A sulfotransferase from a gut microbe acts on diverse phenolic sulfate compounds, including acetaminophen sulfate.\nAbstract: Sulfonation is one of the two main phase II detoxification pathways in eukaryotes which transforms nonpolar compounds into hydrophilic metabolites. Sulfotransferases catalyze these reactions by transferring a sulfo group from a donor to an acceptor molecule. Human cytosolic sulfotransferases use only 3'-phosphoadenosine 5'-phosphosulfate (PAPS) as a donor to sulfonate a variety of chemicals. Less understood are microbial aryl-sulfate sulfotransferases (ASSTs), which catalyze sulfo transfer reactions, without utilizing PAPS as a donor. Currently, the identity of physiological sulfo donor substrates remains unknown and sulfo acceptor substrates are underexplored. With this study, we aim to understand the potential contribution of a gut microbial enzyme to sulfonation chemistry by uncovering its substrate preferences. Here, we show that a sulfotransferase (Bacteroides vulgatus ASST) from the prevalent gut microbe B. vulgatus (now Phocaeicola vulgatus) is a versatile catalyst that utilizes a wide range of phenolic molecules as substrates that are commonly encountered by the host. With this action, it modulates concentrations of donor phenolic sulfates such as acetaminophen sulfate, dopamine sulfate, p-cresol sulfate, and related compounds in vitro and displays broad acceptor flexibility by sulfonating diverse phenolic compounds, including p-coumaric acid, p-cresol, 4-ethylphenol, tyramine, among others. These findings suggest that gut microbial enzymes like ASSTs may contribute to host detoxification of phenolics, a role previously attributed solely to human sulfotransferases. However, further in vivo studies are necessary to understand the potential contributions of ASSTs to host detoxification processes.","41554750":"ID: 41554750\nTitle: C1q-dependent clearance of alpha-synuclein allows macrophages to transiently limit enteric synucleinopathy in male mice.\nAbstract: Deposition of misfolded α-synuclein (αsyn) in the enteric nervous system (ENS) is found in multiple neurodegenerative diseases. It is hypothesized that ENS synucleinopathy contributes to both the pathogenesis and non-motor morbidity in Parkinson's Disease (PD), but the cellular and molecular mechanisms that shape enteric histopathology and dysfunction are poorly understood. Here, we employ a fibrillar injection model of enteric synucleinopathy in male mice and demonstrate that ENS-resident macrophages, which play a critical role in maintaining ENS homeostasis, initially respond to enteric neuronal αsyn pathology by upregulating machinery for complement-mediated engulfment. Pharmacologic depletion of ENS-macrophages or genetic deletion of C1q enhanced enteric neuropathology. Conversely, C1q deletion ameliorated gut dysfunction, indicating that complement partially mediates αsyn-induced gut dysfunction. However, this C1q-dependent clearance mechanism diminished over time and its failure temporally correlated with the further increase in ENS pathology. These findings highlight the importance of enteric neuron-macrophage interactions in removing toxic protein aggregates that putatively shape the gastrointestinal manifestations of PD.","41559934":"ID: 41559934\nTitle: Renalase deficiency suppresses hepatic triglyceride accumulation in the progression to MASLD/MASH by GAN diet in male mice.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a growing public health concern characterized by hepatic triglyceride (TG) accumulation, inflammation, and fibrosis. Renalase is known for its role in blood pressure regulation and catecholamine metabolism, but recent evidence suggests broader cytokine-like functions. Moreover, its involvement in MASLD remains unclear. In this study, we examined the effects of renalase deficiency on hepatic lipid metabolism in a Gubra Amylin NASH (GAN) diet-induced MASLD model using renalase knockout (KO) mice. Our results show that renalase KO mice exhibited reduced hepatic TG levels, accompanied by decreased gene and protein expression of Srebf1 involved in lipid synthesis, and lower gene expressions of antioxidant and fibrosis markers in KO-GAN compared with wild type (WT)-GAN. Additionally, in vitro experiments using AML12 cells with renalase knockdown confirmed reduced intracellular TG accumulation and lipid synthesis gene expression. Notably, the phosphorylation of Akt was significantly reduced in the liver of renalase-KO mice, indicating that Akt signaling plays a critical role in the observed decrease in hepatic TG levels. These findings suggest that renalase regulates hepatic lipid metabolism through the Akt-Srebf1 pathway, and its deficiency attenuates TG accumulation, suggesting that renalase may modulate early hepatic lipid deposition that progresses toward MASLD.","41565402":"ID: 41565402\nTitle: Human umbilical cord MSC-derived exosomes attenuate radiation-induced pulmonary fibrosis via remodeling the gut-lung axis in mice.\nAbstract: To investigate whether human umbilical cord mesenchymal stem cell-derived exosomes (hUC-MSC-Exos) attenuate radiation-induced pulmonary fibrosis (RIPF) through modulation of the gut-lung axis. The therapeutic efficacy of hUC-MSC-Exos was evaluated in a mouse model of RIPF through histopathology and western blot analysis of fibrosis markers (α-SMA, Vimentin, and E-cadherin). Gut barrier integrity (ZO-1, Occludin) and intestinal inflammation (IL-6, IL-1β) were examined using immunohistochemistry, RT-qPCR, and ELISA. Gut microbial composition and metabolic profiles were characterized via metagenomics and untargeted metabolomics, followed by integrated bioinformatics analyses to identify key pathways and metabolites. hUC-MSC-Exos significantly reduced pulmonary collagen deposition and restored fibrosis markers expression, concomitant with enhanced gut barrier function and attenuated intestinal inflammation. Multi-omics analysis revealed restoration of gut microbiota homeostasis and metabolic reprogramming, with the alanine, aspartate, and glutamate pathway being notably co-regulated. L-Glutamic acid was the most significantly altered metabolite and correlated significantly positively with the severity of pulmonary fibrosis and gut dysfunction. Gut microbiota associated with L-Glutamic acid (e.g., Duncaniella, Ruminococcus) were also significantly restructured. hUC-MSC-Exos attenuate RIPF through a comprehensive remodeling of the gut-lung axis, in which L-Glutamic acid and its associated microbiota serve as potential mediators. These findings highlight the gut-lung axis as a promising therapeutic target for RIPF.","41582363":"ID: 41582363\nTitle: Clinical Features of Hypo- and Hypervitaminosis of Fat-Soluble Vitamins in Pediatric Patients.\nAbstract: Fat-soluble vitamins (A, D, E, and K) are crucial for pediatric health, contributing to normal cellular function, growth, immune defense, and development. Unlike water-soluble vitamins, they are absorbed with dietary fats and stored in the liver and adipose tissue, leading to risks of deficiency (hypovitaminosis) and toxicity (hypervitaminosis) in certain physiological and pathological conditions. This narrative review aimed to summarize the clinical manifestations, diagnostic considerations, and management of hypo- and hypervitaminosis of fat-soluble vitamins in pediatric populations. A comprehensive literature review was conducted, highlighting the physiological roles, symptoms of deficiency and toxicity, diagnostic strategies, and treatment options, with particular focus on high-risk groups, including neonates and children with malabsorption or dietary restrictions. Pediatric patients are especially vulnerable to vitamin imbalances due to rapid growth and specific developmental needs. Deficiencies can result in vision problems, bone disorders, immune dysfunction, and coagulation issues, while excess intake can lead to toxicity. Management strategies include clinical assessment, biochemical testing, supplementation, dietary counseling, and public health interventions. Early detection and preventive measures are essential. Future research is needed to explore non-classical roles of these vitamins and optimize supplementation guidelines.","41595985":"ID: 41595985\nTitle: Gut Microbiota and Dopamine: Producers, Consumers, Enzymatic Mechanisms, and In Vivo Insights.\nAbstract: The human gut microbiota plays a key role in neurochemical communication, especially through the gut-brain axis. There is growing evidence that the gut microbiota influences dopamine metabolism through both production and consumption mechanisms. Two key bacterial enzymes are central to this process: tyrosine decarboxylase (TDC), which primarily catalyzes the decarboxylation of tyrosine to tyramine but can also act on L-DOPA to produce dopamine in certain bacterial strains, and aromatic L-amino acid decarboxylase (AADC), which can convert precursors such as L-DOPA, tryptophan, or 5-hydroxytryptophan into bioactive amines including dopamine, tryptamine, and serotonin. Identifying the bacterial families corresponding to TDC and AADC enzymes opens new avenues for clinical intervention, particularly in neuropsychiatric and neurodegenerative disorders, such as Parkinson's disease. Moreover, elucidating strain-specific microbial contribution and host-microbe interactions may enable personalized therapeutic strategies, such as selective microbial enzyme inhibitors or tailored probiotics, to optimize dopamine metabolism. Emerging technologies, including biosensors and organ-on-chip platforms, offer new tools to monitor and manipulate microbial dopamine activity. This article explores the bacterial taxa capable of producing or consuming dopamine, focusing on the enzymatic mechanisms involved and the methodologies available for studying these processes in vivo.","41615647":"ID: 41615647\nTitle: Correlation analysis of gut microbiota and metabolites in gastric cancer patients in plateau areas based on multi-omics technologies.\nAbstract: To characterize gut microbiota alterations and metabolic changes in gastric cancer (GC) patients from high-altitude regions using 16S rDNA sequencing and untargeted metabolomics. Fecal samples from 30 GC patients and 30 healthy controls in Qinghai Province were analyzed. Microbial diversity and composition were assessed via 16S rDNA sequencing, and metabolite profiles were determined using untargeted metabolomics. Correlations between significantly altered microbial taxa and metabolites were evaluated. Microbial diversity differed significantly between groups (P < 0.001). Proteobacteria abundance was higher in GC patients (P < 0.05). At the genus level, Prevotella_9, Streptococcus, and Lactobacillus showed significant differences (P < 0.05-P < 0.001). GC patients exhibited upregulation of desulfo-biotin, glycylproline, glycine, hydroxyhexanoic acid, tyramine, methanethiol oxidase, 5-aminopentanoic acid, citrulline, betaine, and formyl glutamic acid, and downregulation of cytidine, 5'-methylthioadenosine, trehalose, melezitose, lotaustralin, adenosine, creatinine, 5-methyluridine, raffinose, and galactitol. Proteobacteria correlated positively with desulfo-biotin, glycylproline, and glycine, while Lactobacillus correlated with several upregulated metabolites including tyramine and betaine (all P < 0.05). Cytidine correlated negatively with Proteobacteria, whereas creatinine and 5-methyluridine correlated positively with Prevotella_9. GC patients in high-altitude regions display distinct gut microbiota and metabolite profiles, with notable microbe-metabolite associations. These findings suggest potential biomarkers and therapeutic targets for GC in plateau populations.","41628748":"ID: 41628748\nTitle: Effects of aerobic exercise on depression-like behaviors and hippocampal transcriptomics in CSDS-induced adolescent mice.\nAbstract: Adolescence is a critical period of vulnerability to depression, yet most evidence for the antidepressant effects of exercise derives from adult models. This study aims to investigate the effects of aerobic exercise and identify its associated molecular changes in the adolescent depression mouse model. A chronic social defeat stress (CSDS) model was established in adolescent male C57BL/6J mice to induce depression-like behaviors. Thirty-six mice were randomly assigned to three groups: control (CG), model (MG), and model plus exercise (ME). MG and ME mice were subjected to CSDS for two weeks (days 7-20), while ME mice additionally received three weeks of aerobic treadmill training covering the whole CSDS period (days 0-20). Behavioral tests were conducted on days 21-26, followed by the collection of serum and hippocampal tissues for molecular, histological, and transcriptomic analyses. CSDS induced significant depression-like behaviors in adolescent male mice, including social avoidance, anhedonia, and behavioral despair, all of which were effectively alleviated by aerobic exercise. Aerobic exercise appeared to mitigate CSDS-induced neural damage and maintain hippocampal tissue integrity. Moreover, aerobic exercise increased serum levels of serotonin. Transcriptomic analysis identified 587 differentially expressed genes (DEGs). Among these genes, 59 overlapping DEGs were regulated by both CSDS and exercise, and were enriched in carbohydrate metabolism and cholinergic signaling pathways. Aerobic exercise alleviates depression-like behaviors in adolescent male mice, possibly by modulating hippocampal gene expression - especially in cholinergic and carbohydrate metabolism pathways - which provides potential clues to how exercise could influence peripheral monoamine levels and hippocampal structural integrity. These putative mechanisms require further investigation.","41630915":"ID: 41630915\nTitle: Commensal human gut microbes produce species specific neuroactive compounds.\nAbstract: The gut microbiota communicates with multiple organs through neuroactive molecules, but the specific compounds produced remain unclear. We investigated eight commensal gut species, Lactococcus lactis, Enterococcus faecalis, Blautia producta, Clostridium symbiosum, Streptococcus thermophilus, Prevotella copri, Bacteroides fragilis, and Escherichia coli Nissle, using targeted and non-targeted LC-MS/MS. These bacteria differentially consumed glutamine, glutamate, and tryptophan, producing distinct neuroactive metabolites. For example, E. coli and B. producta generated high levels of gamma-aminobutyric acid (GABA), while P. copri was the sole producer of tryptamine. In the tyrosine pathway, E. faecalis synthesized tyramine and dopamine, and L. lactis, B. producta, and E. coli produced L-DOPA. Interestingly, none produced serotonin or its intermediates despite consuming tryptophan. Multiple species also generated short-chain fatty acids (SCFAs). These findings demonstrate that commensal microbes contribute to host neurochemistry by producing diverse neuroactive metabolites and SCFAs, highlighting the therapeutic potential of modulating the gut microbiota to influence human health.","41654159":"ID: 41654159\nTitle: Protective effect of Nootkatone against hippocampal injury in diabetes mellitus with depression via PI3K/AKT pathway: Network pharmacology, molecular docking and experimental validation.\nAbstract: The increasing prevalence of diabetes mellitus with depression (DD) has emerged as a significant global public health concern. Nootkatone (NKT), as a natural sesquiterpenoid compound, exhibits anti-inflammatory, anti-diabetic, and neuroprotective effects. This study aimed to investigate the underlying mechanisms of NKT in treating DD through network pharmacology, molecular docking, and experimental validation. Network pharmacology was utilized to screen the potential targets and mechanisms related to the effects of NKT on DD. Molecular docking was conducted to confirm the interactions between NKT and core targets. The DD model was established through a high-fat diet in conjunction with streptozotocin (STZ) administration and chronic unpredictable mild stress (CUMS). The therapeutic effects of NKT on DD were assessed by indices of glucose metabolism, behavioral tests, H&E staining, enzyme-linked immunosorbent assay (ELISA) and Western blot. Based on network pharmacology and molecular docking analyses, this study proposes the potential mechanisms of NKT on DD, with AKT1 identified as a key target. In vivo experiments demonstrated that NKT improved body weight and glucose metabolism, and alleviated depression-like behaviors in DD mice (P < 0.05). In addition, NKT attenuated neuronal injury and increased monoamine neurotransmitters in the hippocampus (P < 0.05). NKT also decreased inflammatory response induced by STZ-CUMS and upregulated proteins associated with PI3K/AKT pathway (P < 0.05). NKT alleviated depression-like behaviors, attenuated hippocampal injury, and increased monoamine neurotransmitters in DD mice. The protective effect of NKT on DD might be associated with the activation of the PI3K/AKT pathway.","41654297":"ID: 41654297\nTitle: Gastrointestinal dysfunction in critically ill patients: A prospective observational study of frequency, severity, risk factors, and outcomes.\nAbstract: Gastrointestinal dysfunction (GD) is common in intensive care patients with a wide range of admission diagnoses. Whether GD increases the severity and worsens outcomes from critical illness remains contentious. The aim of this study was to determine the frequency, severity, and risk factors associated with the development of GD in intensive care patients and to correlate these with clinical outcomes. Adult critically ill patients receiving enteral and/or parenteral nutrition with an expected ICU stay ≥72 h were prospectively studied between February 2019 to July 2020. Predefined GI signs and symptoms, ICU interventions, organ scoring, and clinical outcomes were documented from admission to ICU discharge or at 90 days. Data on GD using the Acute Gastrointestinal Injury (AGI) and Gastrointestinal Dysfunction Score (GIDS) scoring systems were collected, and associations between GD and clinical outcomes (ICU length of stay, mechanical ventilation duration, and mortality) were analysed using logistic regression and Poisson mixed-effects models with fixed and random effects, adjusting for age, illness severity, and other covariates. Of 2247 ICU patients screened, a convenience sample of 100 patients were enrolled (75 general ICU, 25 cardiac ICU; 61 % male; median age 53 years [range 41-82]). All patients had at least one GI dysfunction sign/symptom. Gut dysfunction was present in all patients based on the AGI and 79 % by the GIDS. Severe GD occurred in 46 % (AGI) and 25 % (GIDS). A gut-related ICU admission diagnosis was present in 23 % of patients, which increased the odds of severe GD (AGI OR 9.8, 95 % CI 2.66-31.83, p < 0.001; GIDS OR 4.3, 95 % CI 1.4-13.0, p = 0.01). Elevated serum lactate was associated with GD severity (AGI OR 1.30, p = 0.04; GIDS OR 1.32, p = 0.02). Severe GD was associated with longer ICU stays (median 13 vs 10 days, p = 0.02) and mechanical ventilation duration (12 vs 10.5 days, p = 0.05). A 1-Litre fluid balance was associated with an increase in AGI grading of 5.1 % (p = 0.02) and GIDS of 7.9 % (p < 0.001). Aggressive enteral feeding increased AGI odds by 82 % (OR 1.82, p = 0.015). Multiple inotropes were associated with higher GIDS at 72 h (p = 0.023). ICU mortality was 21 %, with no differences by GD. These findings support the importance of consistent GD assessment to guide clinical decision-making in critical care. There is an urgent need for a robust, standardised, and objective approach to GD assessment in ICU practice, one that accounts for severity, dynamic risk factors, and the potential to alter clinical outcomes through timely recognition and intervention.","41672155":"ID: 41672155\nTitle: Nutritional and metabolic signatures in pediatric phenylketonuria and hyperphenylalaninemia: Insights from untargeted urinary metabolomics.\nAbstract: Dietary interventions are essential for managing phenylketonuria (PKU) and may influence metabolic regulation beyond phenylalanine control. We characterized the urinary metabolomic fingerprint of pediatric participants (n=82) recruited into clinical phenotypes: PKU, PKU with response to tetrahydrobiopterin (BH4), and hyperphenylalaninemia (HPA), as well as sex- and age-matched healthy children controls. Untargeted metabolomics (HPLC-Q-TOF-MS/MS) revealed 59 discriminant metabolites across multiple biochemical pathways, including phenylalanine, tryptophan, and caffeine metabolisms, as well as metabolites related to dietary exposure or gut microbial metabolism. Distinct urinary signatures were described across phenotypes. Phenylalanine-related pathways predominated in PKU, accompanied by increased excretion of vitamin derivatives, consistent with protein substitute supplementation. In contrast, reduced levels of non-phenylalanine amino acid derivatives, methylhistidines, creatine, and branched-chain amino acid-related metabolites were observed in PKU, suggesting alterations in muscle metabolism or natural protein intake. Microbiota-derived metabolites were also less represented in PKU, indicating potential effects of dietary restrictions on gut-host metabolic interactions. HPA individuals showed a urinary fingerprint closer to controls, whereas the BH4 subgroup exhibited the greatest metabolic heterogeneity, reflecting variability in dietary and pharmacological treatment responses. These findings reveal metabolic diversity within the pediatric PKU spectrum driven by clinical phenotype and nutritional management. Urinary metabolomics may support more precise monitoring of metabolic health status and guide precision nutrition strategies in PKU and HPA from early life.","41683364":"ID: 41683364\nTitle: Fermented Foods and the Gut-Liver Axis: Modulation of MASLD Through Gut Microbiota.\nAbstract: Background/Objectives: Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) is a prevalent condition defined by hepatic fat accumulation, inflammation, and metabolic dysregulation. Current evidence demonstrates that gut microbiota and their metabolites are associated with MASLD pathogenesis. Fermented foods, rich in live microbes and bioactive compounds, actively modulate the gut-liver axis and influence disease progression. This narrative review provides a comprehensive summary of current evidence on the impact of fermented foods on gut microbiota, intestinal barrier function, and gut-liver interactions, and demonstrates their potential role in preventing or mitigating MASLD. Methods: A comprehensive literature search of preclinical and clinical studies was conducted. Specifically, the review focused on fermented-food interventions, modulation of gut microbiota, metabolite production, and effects on hepatic metabolism and inflammation. Results: This review found that fermented foods provide probiotics, prebiotics, short-chain fatty acid (SCFAs), and bioactive compounds that enhance microbial diversity, improve intestinal barrier integrity, reduce endotoxemia, and modulate bile acid and lipid metabolism. Evidence from animal and human studies indicates that fermented food consumption can attenuate hepatic steatosis, inflammation, and metabolic dysregulation, with variability depending on individual microbiome composition. Conclusions: Altogether, these findings suggest that fermented foods represent a promising adjunctive dietary strategy for MASLD by modulating the gut-liver axis and supporting metabolic and hepatic health. Personalized approaches and further long-term clinical trials are required to optimize interventions and establish evidence-based recommendations.","41707058":"ID: 41707058\nTitle: Coreopsis Tinctoria Nutt.

This study investigated the protective effects of Coreopsis tinctoria Nutt. polyphenolic (CTNP) extract against intestinal barrier damage in a mouse model of depression induced by chronic unpredictable mild stress (CUMS). CTNP alleviated depressive-like behaviors and enhanced intestinal integrity, as evidenced by decreased serum levels of lipopolysaccharide (LPS) and diamine oxidase (DAO), as well as increased expression of tight junction proteins (Occludin, ZO-1, and MUC2). Furthermore, CTNP reduced the production of pro-inflammatory cytokines (IL-1β, TNF-α, and IL-6) in colon tissue, potentially through inhibition of the TLR4/MYD88/NF-κB signaling pathway. These findings elucidate the underlying mechanism of CTNP's protective effects in depression-related intestinal injury and provide both theoretical insights and practical implications for future research.","41714630":"ID: 41714630\nTitle: Short lifespan under dietary cholesterol depletion is associated with gut dysfunction in Drosophila melanogaster females.\nAbstract: Dietary restriction may extend lifespan by improving late-life gut health. Because micronutrients mediate the effects of macronutrient ratios on longevity, we examined how cholesterol limitation affects gut health in female Drosophila melanogaster. Low-cholesterol diets increased intestinal permeability and reduced lifespan, however, not all flies lost barrier function before dying. This indicates gut dysfunction is either a marker of ageing, or contributes to death, but predominantly during dietary cholesterol limitation.","41722523":"ID: 41722523\nTitle: Comprehensive analysis of spoilage characteristics of refrigerated hairtail by microbiome and metabolomics.\nAbstract: Hairtail is prone to spoilage during refrigerated storage and it is due to microbial activity, which will directly lead to changes in the composition of metabolites in vivo. This study systematically elucidates the spoilage phenomena in hairtail during eight days of refrigeration at 4 °C through multi-omics analysis. Pseudomonas and Shewanella were identified as key spoilage bacteria, and their nutrient utilization pathways were different Pseudomonas dominated the early stage and used monosaccharides; however, Shewanella appeared in the later stage, and its metabolism is heavily dependent on amino acids and nitrogen-containing compounds such as TMAO released in large quantities in the later stage of spoilage. Non-targeted metabolomics results revealed a total of 62 differentially expressed metabolites. Metabolic pathway enrichment analysis revealed that cysteine and methionine metabolism, tyrosine metabolism and nucleotide metabolism played pivotal roles in the putrefaction process. Moreover, the study identified 7 metabolites (such as Lys-Met, Nicotinic Acid Adenine Dinucleotide) that showed a significant correlation with the dominant spoilage bacterium Pseudomonas through correlation analysis; while two other metabolites (such as Inosine 5'-Monophosphate, Tyramine) were significantly correlated with the primary spoilage bacterium Shewanella. The integration of microbiome and metabolomics analyses has enabled the precise identification of key spoilage microorganisms and metabolites in chilled hairtail, providing crucial evidence for developing targeted preservation techniques.","41730497":"ID: 41730497\nTitle: How cytochrome P450 enzymes in humans are involved in Parkinson's disease: a literature review.\nAbstract: This review synthesizes three decades of evidence regarding the role of cytochrome P450 enzymes (CYPs) in Parkinson's disease (PD), revealing their multifaceted roles beyond traditional pesticide metabolism. While CYP2D6 remains the most studied enzyme due to its association with PD risk in poor metabolizer phenotypes and its dual role in dopamine (DA) synthesis (directly via tyramine hydroxylation and indirectly through precursor demethylation), recent research has highlighted less-studied CYPs with critical pathological implications. Another focal enzyme, CYP2E1, mediates the bioactivation of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine to its neurotoxic metabolite, 1-methyl-4-phenylpyridinium, thereby inducing oxidative stress. It also partially contributes to DA oxidation, a process that generates multiple cytotoxic byproducts. These toxic products are implicated in two major pathological processes involved in the development of PD-oxidative stress and protein misfolding-which adversely affect dopaminergic neurons. Additionally, CYP3A4 converts acetaminophen to N-acetyl-p-benzoquinone imine in the substantia nigra, contributing to dopaminergic neuron loss. Emerging enzymes like CYP7B1 (which reduces midbrain DA neuron survival via 7α,26-dihydroxycholesterol) and CYP46A1 (inhibiting α-synuclein aggregation) further expand the involvement of the CYP network in PD. The CYP4 family has also emerged as regulators of fatty acid and eicosanoid metabolism, linking to neuroinflammation and oxidative stress. While CYP2D6 and CYP2E1 have dominated prior studies, this review underscores the broader impact of the CYP superfamily on PD pathogenesis through interconnected pathways involving xenobiotic detoxification, fatty acid homeostasis, cholesterol clearance, and neuroinflammation. By integrating these diverse mechanisms, this study establishes a multifactorial framework that connects CYP-mediated biochemical cascades to PD pathogenesis. SIGNIFICANCE STATEMENT: This article addresses the role of various Cytochrome P450 enzymes (CYPs) in Parkinson's disease (PD), covering both their biochemical functions and how genetic, epigenetic, and environmental factors influence PD progression. Recent findings on CYPs, particularly CYP2D6 and CYP2E1, and their involvement in PD pathogenesis through mechanisms such as pesticide metabolism, dopamine synthesis, and oxidative stress, are summarized. We also explore the contribution of lesser-studied CYPs, like CYP46A1 and CYP39A1, in cholesterol and fatty acid metabolism, presenting novel insights for therapeutic development. The review additionally touches on the influence of CYPs on disease biomarkers and therapeutic strategies, which may hold potential for both clinical application and personalized treatment of PD. Unlike prior reviews focused on CYP2D6 and CYP2E1, this work consolidates evidence for a broader CYP network in PD, highlighting novel therapeutic targets in cholesterol and fatty acid metabolism pathways.","41754858":"ID: 41754858\nTitle: Diet and Gut Microbiota in Inflammatory Bowel Disease: A Clinical and Nutritional Perspective.\nAbstract: Inflammatory bowel diseases, comprising Crohn's disease and ulcerative colitis, represent chronic inflammatory disorders with rising global incidence, underscoring the pivotal role of modifiable environmental factors in disease pathogenesis. Diet and intestinal microbiota have emerged as critical bidirectional therapeutic targets through complex interactions with host immune responses. Epidemiological evidence demonstrates that healthy and high fiber diets reduce disease risk, while ultra-processed foods and inflammatory dietary patterns increase susceptibility. Therapeutic nutritional interventions, including exclusive enteral nutrition, the Crohn's Disease Exclusion Diet combined with partial enteral nutrition, and the Mediterranean diet can induce and maintain clinical remission while promoting favorable microbiome modifications characterized by the enrichment of butyrate-producing taxa such as Faecalibacterium prausnitzii and Roseburia species, alongside a reduction in pathogenic Proteobacteria. Micronutrient deficiencies affect up to 78% of patients through malabsorption, chronic blood losses, dietary restrictions, and drug-nutrient interactions. Nutritional status significantly impacts surgical outcomes, with preoperative malnutrition and sarcopenia associated with increased postoperative complications, and it reciprocally influences biologic therapy response. Integration of personalized, microbiome-informed dietary strategies as complementary components of comprehensive treatment plans represents a promising therapeutic frontier, requiring multidisciplinary collaboration, rigorous clinical trials with standardized microbiome analyses, and precision nutrition algorithms accounting for disease phenotype, baseline microbial composition, and individual patient characteristics to optimize outcomes and improve quality of life.","41771902":"ID: 41771902\nTitle: Gut ecosystem dysfunction in parkinson's disease: deciphering faecal metabolome-metagenome links for novel diagnostic panels.\nAbstract: Gut ecosystem dysfunction is implicated in Parkinson's disease (PD), but integrative faecal metabolome-metagenome links are undefined. We explored these interactions in Chinese PD patients to develop diagnostic panels. Targeted faecal metabolomics (LC‒MS/MS) was performed on 132 PD and 113 healthy controls (HCs) and shotgun metagenomics was integrated for 39 PD/HC pairs. We identified 33 significantly altered faecal metabolites in PD (FDR-P < 0.05). A novel 12-metabolite panel could distinguish PD from HCs. Multi-omic integration revealed gut ecosystem dysfunction manifests via co-disruptions in microbial genes (e.g., amino acid metabolism genes) and metabolites. Critically, a combinatorial diagnostic panel integrating faecal metabolites and microbial gene markers achieved exceptional PD detection (AUC = 0.961, 95% CI = 0.923-0.998). This study deciphers metabolome-metagenome links driving gut dysfunction in PD, identifying amino acid metabolism as a core perturbed pathway. The novel diagnostic panels provide mechanistic insights and clinical tools for PD precision diagnosis.","41775000":"ID: 41775000\nTitle: Yeast probiotic protects gut microbiota diversity and metabolic potential against Cryptosporidiosis-induced disruption in goat kids.\nAbstract: Cryptosporidiosis, caused by Cryptosporidium parvum, is a major cause of enteric disease and gut microbiota disruption in neonatal ruminants. It can lead to impaired growth, increased susceptibility to pathogens, and long-term gut dysfunction. In this study, we investigated whether supplementation with a live yeast probiotic (Saccharomyces cerevisiae Sc47) could help preserve gut microbiota resilience and functional homeostasis during an experimental C. parvum oral infection in goat kids. Thirty male French Alpine goat kids were assigned to three groups: uninfected control (healthy), infected, and infected with yeast supplementation. Longitudinal 16S rRNA gene sequencing, network analysis, and functional metagenomic predictions were used to assess microbial diversity, community composition, co-occurrence patterns, and metabolic potential, with a focus on short-chain fatty acid (SCFA) biosynthesis. Infection induced marked dysbiosis, characterised by a substantial reduction in microbial richness and a widespread loss of SCFA-producing commensals and metabolic functions. In contrast, yeast supplementation significantly reduced oocyst excretion by more than 84% throughout the experiment, attenuated pathogen-induced community shifts, and maintained beneficial genera such as Butyricicoccus and members of the Oscillospiraceae family. Furthermore, network analysis revealed that probiotic treatment preserved microbial association structures and reduced community fragmentation. Consistent with these findings, functional profiling showed the retention of pathways involved in carbohydrate metabolism, amino acid biosynthesis, and SCFA production, suggesting enhanced microbiota resilience. These findings demonstrate that S. cerevisiae supplementation can mitigate infection-associated dysbiosis by controlling pathogenic overgrowth while sustaining commensal bacterial stability and functional capacity. This highlights its potential as a microbiota-targeted strategy to support gut health in neonatal ruminants.","41779254":"ID: 41779254\nTitle: Microbiome alterations and their potential impact on infection risk in chronic kidney disease and end-stage kidney disease: a narrative review.\nAbstract: Chronic kidney disease [CKD] is associated with profound alterations of both gut microbiota composition and functions, commonly referred to as gut dysbiosis. These changes are driven by several factors such as dietary restrictions, medications, and uremia, which further contribute to patients with CKD to their pro-inflammatory and immunocompromised state. Recent evidence suggests that dysbiosis may also increase susceptibility to infections, which remain a leading cause of morbidity and mortality in CKD patients. In this review, we aimed at examining the features of the altered gut microbiome in patients with CKD, its potential role in promoting infection risk, and current therapeutic strategies targeting the gut microbiota to mitigate CKD-related complications.","41786890":"ID: 41786890\nTitle: The short-chain fatty acid butyrate prevents gut-brain amyloid-β pathology and neuroinflammation in an Alzheimer mouse model.\nAbstract: Amyloid-β (Aβ) plays a critical role in Alzheimer's disease (AD) and its accumulation in the brain is pivotal to disease progression and precedes memory and neuronal loss. Besides the severely handicapping brain symptoms, AD patients display early gastro-intestinal (GI) manifestations such as upper and lower GI dysmotility, in particular constipation. Although there is increasing evidence of Aβ accumulation in the gut, its pathogenic effects on enteric nervous system (ENS) connectivity and gut function as well as underlying pathophysiological mechanisms are poorly understood. Furthermore, studies have reported a gut to brain transmission of Aβ that causes memory deficits in mice. Therefore, identifying therapeutics which can reduce Aβ accumulation in the gut at an early stage of the disease could have the advantage of slowing or even reversing disease progression before severe alterations or irreversible damages at both intestinal and brain levels. Hence, in this study, we investigated the capacity of the short-fatty acid butyrate to restore Aβ-driven alteration of ENS connectivity and gut-brain functions in the SAMP8 mouse model of AD. Here we show that SAMP8 mice display a gut amyloid pathology, an alteration of ENS connectivity and gut defects prior to memory decline. BACE1, an Aβ-producing enzyme, expression and activity are increased whereas neprilysin, an Aβ-degrading enzyme, is decreased in the gut of SAMP8 mice, indicating a rise in the Amyloid Precursor Protein (APP) holoprotein processing and a reduction of Aβ clearance which promote an amyloidosis. In primary ENS cultures, Aβ causes a degradation of synaptic-associated proteins EphB2 and synaptophysin, leading to an alteration of ENS connectivity. In wild-type mice, intra-colon delivery of Aβ alters ENS connectivity and causes subsequent GI symptoms, recapitulating the phenotype of the SAMP8 mouse model of aging and AD. Moreover, Aβ impairs ENS connectivity in human induced pluripotent stem cell (iPSC)-derived intestinal organoids and explant cultures of human colon, indicating that Aβ causes ENS lesions in models of the human gut. Butyrate, a short-chain fatty acid derived from bacterial metabolism, reduces Aβ secretion and preserves enteric neuronal connectivity in vitro and in vivo, and blocks Aβ accumulation in the gut, brain and plasma in SAMP8 mice. In addition, butyrate ameliorates neuroinflammation and prevents gut dysfunction and memory deficit. Collectively, these findings suggest that Aβ promotes gut symptoms through alteration of ENS connectivity and butyrate counteracts these impairments with an amelioration of neuroinflammation and memory function in AD model.","41795531":"ID: 41795531\nTitle: Enhancing safety and flavor of traditional Yucha: Autochthonous starters from Hainan fermented foods reduce biogenic amines and promote taste-active metabolites.\nAbstract: Yucha, a traditional fermented rice-fish product, faces challenges in inconsistent quality and safety. In this study, 69 lactic acid bacteria (LAB) were isolated from Yucha and shrimp paste in Hainan, China. Four strains, Lactiplantibacillus plantarum Lpl-YC37, Lacticaseibacillus paracasei Lpa-XJ120, and Pediococcus pentosaceus Ppe-YC39 and Ppe-XJ37 were selected as starters based on probiotic property and safety evaluation. Inoculation with these LAB starters significantly enriched beneficial metabolites, with Ppe-XJ37 showing a four-fold increase in acetic acid, the dominant short-chain fatty acids. Additionally, all LAB inoculation enhanced free amino acids, particularly L-glycine, improving flavor and nutritional value. Crucially, LAB inoculation drastically suppressed biogenic amines, reducing putrescine from 55.23 μg g-1 in the control to 5.77 μg g-1 in the Lpl-YC37 group, highlighting improved safety. These findings demonstrate that tropical fermented foods harbor indigenous LAB starters, providing a scalable approach to modernize these foods for improved quality and safety.","41796714":"ID: 41796714\nTitle: In vitro inhibition of monoamine transport by amphetamine-like pre-workout supplement ingredients.\nAbstract: Phenethylamine (PEA) and alkylamine (AA) analogues are a prominent group of pre-workout food supplement ingredients. They are structurally related to the stimulant amphetamine and to the endogenous catecholamines noradrenaline and dopamine, implying potential cardiovascular and psychological effects. This study systematically investigated the inhibitory potential of 12 PEAs and 4 AAs identified in pre-workout supplements on the human dopamine transporter (hDAT), human noradrenaline transporter (hNET) and human serotonin transporter (hSERT) that are stably overexpressed in HEK 293 cells. All PEAs and AAs tested, except DMAE, inhibited substrate uptake by one or more monoamine transporters. Overall, the substances displayed the highest potency and efficacy at hNET, followed by hDAT and with considerably weaker effects on hSERT. At hNET, potency values (IC50) ranged from 0.5 µM to 123 µM, with maximal inhibition (Emax) ranging from -59.2% to -120%. Inhibition of substrate uptake by hDAT occurred with IC50 values between 4.0 and 95.8 µM and Emax values between -66.8% and -135%. For hSERT 50% inhibition was observed at concentrations ranging from 2.6 µM to 131 µM, with maximal effect between 85.3% and -64.8%. These findings indicate a potential for sympathetic activation and behavioral rewarding and reinforcing effects. Notably, the in vitro potency and efficacy of several PEAs and AAs were comparable to those of the well-known illicit stimulants amphetamine and cocaine. Together, these findings highlight the urgent need to further characterize pharmacokinetic and pharmacodynamic properties of these pre-workout supplement ingredients to support robust risk assessment and informed regulatory decision-making regarding the safety of pre-workout supplement ingredients.","41819674":"ID: 41819674\nTitle: In vitro and in vivo toxicological safety assessment of indigenous probiotic Lacticaseibacillus rhamnosus NCDC 610.\nAbstract: Lacticaseibacillus rhamnosus NCDC 610, isolated from the cereal-based fermented milk product Rabdi, has previously demonstrated antimicrobial, immunomodulatory, hypocholesterolemic, and antidiabetic properties. To ensure its safe application in foods and probiotic formulations, a comprehensive preclinical safety assessment was performed in accordance with ICMR and OECD guidelines. A battery of in vitro and in vivo assays was conducted to evaluate virulence factors, mucin degradation, biogenic amine production, antibiotic susceptibility, cytotoxicity in HT-29 cells, and adhesion ability. Additionally, acute and sub-acute oral toxicity studies were performed in C57BL/6 mice, including haematological, biochemical, histopathological, and immunological parameters. Lcb. rhamnosus NCDC 610 lacked virulence-associated attributes and did not exhibit haemolytic, gelatinase, coagulase, DNase, β-glucosidase, or β-glucuronidase activities. It neither utilized mucin nor produced biogenic amines, as confirmed by colourimetric and HPLC analyses. Further, Lcb. rhamnosus NCDC 610 was susceptible to clinically relevant antibiotics, maintained >95% cell viability in HT-29 cells, and showed moderate adhesion to intestinal epithelial cells. In vivo studies revealed no treatment-related toxicity, behavioural abnormalities, organ damage, bacterial translocation, or adverse immune responses. Collectively, these findings demonstrate the in vitro and in vivo safety of Lcb. rhamnosus NCDC 610 and support its potential for further evaluation as a functional probiotic candidate.","41826862":"ID: 41826862\nTitle: Dietary recommendations for patients with chronic liver diseases: the need for increased awareness among non-hepatologist physicians.\nAbstract: BACKGROUND& AIM: Nutritional awareness is a significant challenge for patients with chronic liver diseases (CLD), especially for those with conditions such as ascites, hepatic encephalopathy, and fatty liver disease. This survey aims to assess nutritional awareness regarding liver disease among healthcare providers (hepatologists and non-hepatologists). METHODS: A structured online questionnaire was created based on clinical knowledge and established guidelines related to nutrition in liver disease. The survey consisted of 13 questions addressing nutritional considerations for liver disease patients. RESULTS: A total of 124 out of 362 survey recipients responded. Among them, 60.5% were hepatologists, while the remaining respondents included general practitioners, endocrinologists, and cardiologists. Hepatologists were more likely than non-hepatologists to recognize the significance of nutritional guidance for their patients, with 74.7% of hepatologists supporting this view compared to only 40.8% of non-hepatologists (p < 0.001). For patients with compensated cirrhosis, 82.7% of hepatologists preferred no dietary restrictions, whereas only 46.9% of non-hepatologists agreed (p < 0.001). Both groups favored protein restriction in cases of hepatic encephalopathy, (p = 0.2). Regarding patients with ascites, both hepatologists and non-hepatologists recommended salt restriction, with hepatologists showing a stronger inclination. When it comes to alcohol consumption, 80% of hepatologists and 61.2% of non-hepatologists favored restricting alcohol intake in patients with chronic liver disease (p = 0.03). CONCLUSION: There are notable differences in nutritional priorities and recommendations between hepatologists and non-hepatologists. There is a pressing need to raise awareness among non-hepatologist physicians concerning dietary recommendations for patients with chronic liver disease.","41834256":"ID: 41834256\nTitle: In Silico and In Vitro Therapeutic Effects of Phycocyanin Against Lipid Micelle and/or Endotoxin-Induced Oxidative Damage and Barrier Dysfunction in Human Intestinal Epithelial Cells Model.\nAbstract: Obesity is associated with chronic intestinal inflammation, oxidative stress, and disruption of epithelial barrier integrity. Phycocyanin (PHY), a bioactive pigment from Spirulina platensis, is known for its antioxidant and anti-inflammatory activities. This study was conducted to evaluate the protective effect of PHY on the disruption of the intestinal epithelium induced by repeated lipid micelles (LM) and/or inflammation induced by lipopolysaccharides (LPS) in the Caco-2 cell line. Firstly, we evaluated the protective actions of PHY against cytotoxicity, oxidative stress imbalance, inflammatory response, and epithelial barrier alteration through an in vitro model, the intestinal Caco-2 cells, treated with LPS and/or LM. We also conducted an in silico molecular docking with PHY. In vitro, PHY was not cytotoxic to Caco-2 cells; instead, it improved cell viability, demonstrated antioxidant and inflammation-suppressing effects, preserved tight junction organization, and protected against endoplasmic reticulum (ER) stress, thereby maintaining epithelial barrier integrity. In silico analysis revealed strong binding affinity of PHY to antioxidant enzymes (SOD, CAT) and favorable interactions with pro-inflammatory cytokines (TNF-α, IL-6), supporting its regulatory potential. Taken together, these findings indicate that PHY protects Caco-2 cells, preserving intestinal barrier integrity under oxidative and inflammatory stress, and may serve as a natural therapeutic candidate against obesity-related gut dysfunction.","41837770":"ID: 41837770\nTitle: Magnesium Deficiency Accelerates Gut Aging and Increases Susceptibility to Colitis.\nAbstract: Aging is linked to a higher incidence of gut diseases such as inflammatory bowel disease (IBD), yet the underlying mechanisms remain unclear. We identified an age-related decline in magnesium (Mg) levels specifically in the gut across species, prompting investigation of its role in intestinal health. Functional studies demonstrated that Mg restriction accelerates gut aging in old but not in young mice and aggravates colitis severity. Multi-omics analysis of mouse tissues revealed that dietary Mg deficiency reshapes the phosphoproteome and N-glycoproteome, destabilizing adhesion complexes, a hallmark of intestinal aging and inflammation. In the UK Biobank cohort (n = 182,213), dietary Mg intake was inversely correlated with gut disorder risk, with 334.7-420.0 mg/day conferring significant protection against Crohn's disease, ulcerative colitis, irritable bowel syndrome, and diverticular disease. These findings identify Mg homeostasis as a key regulator of gut health and highlight Mg supplementation as a potential strategy to counteract age-related gut dysfunction.","41840712":"ID: 41840712\nTitle: Characterization of age-related changes in the gut microbiome and metabolome of Kunming dogs and their associations with police performance.\nAbstract: Gut microbiota plays a pivotal role in regulating the host's central nervous system (CNS) activity and behavior. However, its influence on the police performance of Kunming dogs and the underlying mechanisms remain largely unexplored. This study was the first to apply multi-omics technologies to investigate the dynamic variations in gut microbiota and their metabolic profiles across different ages of Kunming dogs. Furthermore, we systematically examined the associations between these microbial alterations and police performance metrics, providing a theoretical foundation for enhancing the working capabilities of Kunming dogs through targeted modulation of intestinal microecology. The study showed that puppies, young dogs and adult dogs had significantly better police performance than elderly dogs, with young dogs exhibiting the highest scores. Analysis of 16S rRNA sequencing demonstrated that gut microbial diversity and stability were highest during the young dog stage, gradually declining with age. Metagenomic analysis revealed that the abundance of Lactobacillus acidophilus, Lactobacillus johnsonii, Limosilactobacillus reuteri, Ligilactobacillus animalis and Muribaculum gordoncarteri were strongly correlated with police performance. The results of metagenome-assembled genomes (MAGs) indicated that the above species have functional genes involved in GABAergic and glutamatergic synapse pathways. Furthermore, metabolomic analysis showed that differential metabolites were enriched in the neuroactive ligand-receptor interaction pathway, in which GABA (γ-aminobutyric acid), histamine and tyramine metabolites were positively correlated with the above species and police performance. The species L. acidophilus, L. johnsonii, L. reuteri, L. animalis, and M. gordoncarteri, which were enriched in the gut of puppies and young Kunming dogs, may potentially influence the nervous system through the production of neurotransmitters and neuromodulators, suggesting a possible association with police performance.

Digestion of lactose relies on the intestinal enzyme lactase, or lactase-phlorizin hydrolase, located on the brush border of the small bowel mucosa. This enzyme splits lactose into two absorbable monosaccharides: glucose and galactose. When lactase activity is insufficient, undigested lactose proceeds to the colon where it is fermented by the gut flora, generating gas that trigger the uncomfortable symptoms associated with lactose intolerance. Lactase non-persistence is extremely common, affecting approximately 70% of the adult population world-wide. Prevalence varies markedly across geographic regions, typically ranging from 50 to 90% in African, Asian, and South American countries. The subjective diagnosis of lactose intolerance requires the occurrence of symptoms such as abdominal pain, bloating, flatulence and diarrhea following the ingestion of high lactose dairy products. An objective assessment of lactose intolerance may be achieved with a specific breath test that measures hydrogen emission in breath following the ingestion of lactose. Consequently, current international guidelines require concurrent report of typical symptoms and pathologic breath test results in order to diagnose lactose intolerance. Management of lactose intolerance often involves dietary restrictions and the prescription of formulations that contain lactase. However, one should recognize that avoiding dairy products can increase the risk of nutritional deficiencies. Therefore, ongoing research is focused on alternative strategies, notably utilizing gut microbiota in order to improve tolerance to lactose. This review aims to explore the evidence supporting the use of probiotics as a potential treatment strategy to alleviate the symptoms of lactose intolerance by modulating colonic metabolism and enhancing lactose digestion.","41850537":"ID: 41850537\nTitle: Enteric and Sympathetic Nervous System Pathways Mediate Early Life Stress Effects on Gut Motility and Pain: Mechanistic Findings With Human Correlation.\nAbstract: Adverse experiences during early life can disrupt gut-brain axis development, but the mechanisms linking early life stress (ELS) to long-term gastrointestinal dysmotility and pain remain unclear. We used a maternal separation (MS) mouse model of ELS and assessed visceral pain sensitivity, intestinal motility, and enteric nervous system (ENS) composition. Two large human pediatric population cohorts were also analyzed for associations between ELS and disorders of gut-brain interaction (DGBI) risk. MS in mice led to visceral hypersensitivity, sex-specific motility defects, and altered ENS composition, including increased serotonergic innervation and changes in subtype-specific neuronal proportions. Degarelix-mediated suppression of gonadal hormones reversed MS-induced visceral pain and motility defects, implicating sex hormones in long-term gut changes. MS led to enhanced sympathetic innervation of the ENS and chemical sympathectomy restored normal motility, suggesting sympathetic overactivity in ELS-related gut dysfunction. In humans, significant associations between maternal mental health problems and pediatric DGBI were observed in both cohorts, mirroring preclinical findings. These results identify ELS-driven changes in enteric, sensory, and sympathetic pathways as contributors to DGBI risk and offer insight into potential therapeutic targets.","41857429":"ID: 41857429\nTitle: Python metabolomics uncovers a conserved postprandial metabolite and gut-brain feeding pathway.\nAbstract: Most mammals consume small and frequent meals. By contrast, pythons are ambush predators that exhibit extreme feeding and fasting patterns and provide a unique model for uncovering molecular mediators of the postprandial response1-3. Using untargeted metabolomics, we show that circulating levels of the metabolite para-tyramine-O-sulphate (pTOS) are increased more than 1,000-fold in pythons after a single meal. In pythons, pTOS production occurs in a microbiome-dependent manner via sequential decarboxylation and sulphation of dietary tyrosine. In both pythons and mice, pTOS administration activates a neural population in the ventromedial hypothalamus (VMH). In mice, these VMH neurons are required for the anorexigenic effects of pTOS. Chronic administration of pTOS to diet-induced obese male mice suppresses food intake and body weight. pTOS is also present in human blood, where its levels are increased after a meal. Together, these data uncover a conserved postprandial anorexigenic metabolite that links nutrient intake to energy balance.","41872639":"ID: 41872639\nTitle: Early intestinal barrier changes in A53T transgenic Parkinson's disease mice.\nAbstract: Gut dysfunction commonly precedes motor symptoms in Parkinson's disease (PD), but the mechanistic sequence of gut versus brain pathology remains unclear. This work aimed to define the timing of intestinal barrier dysfunction relative to central nervous system (CNS) changes in the A53T α-synuclein transgenic mouse model of PD. Functional and molecular assessments of the gastrointestinal tract (ileum and colon) were conducted at 12 and 36 weeks. We measured in vivo and ex vivo intestinal permeability, nutrient absorption, histomorphology, goblet cell density, and expression of MUC2 and Claudin-1. Inflammatory markers (CRP, TNF-α, CD45) were quantified in plasma and gut tissues. A53T mice exhibited increased intestinal permeability at 12 and 36 weeks, with transiently elevated ex vivo transepithelial electrical resistance (TER) at 12 weeks. Nutrient absorption remained intact. Morphological changes included widened villi and crypts, altered mucin expression, and early reductions in Claudin-1 in the ileum and the colon while inflammatory markers remained largely unchanged. These findings suggest that gut dysfunction precedes known central pathology in A53T mice, supporting further investigation into the gut as an early site of pathology and a potential therapeutic target in PD.","41876037":"ID: 41876037\nTitle: Behavioral deficits, organ weight changes, and altered gut microbiota in single-housed middle-aged mice.\nAbstract: In this study, we uncovered novel and intriguing effects of aging on mouse behavior, brain neurotransmitter levels, and gut microbiota, with a particular focus on the transition from young adulthood to middle age. Using C57BL/6 J male mice of different ages (young adults at 12 weeks, middle-aged at 30 weeks, and older middle-aged mice at 45 weeks), we observed notable changes. Middle- and older middle-aged mice exhibited reduced spontaneous activity and shorter central stay times in the open field test compared to young adult mice. Nesting behavior was also delayed in older middle-aged mice. In the novel object recognition test, long-term memory was impaired in middle-aged and older middle-aged mice. However, the concentrations of brain neurotransmitters (such as γ-aminobutyric acid and serotonin) and their precursor amino acids in the prefrontal cortex did not vary significantly with age. Analysis of the cecal microbiota revealed age-related changes in bacterial composition. Specifically, Deferribacterota was significantly more abundant in the middle-aged mice than in the young adult mice, and Pseudomonadota was more abundant in older middle-aged mice than in young adult mice. In conclusion, our study provides an integrative descriptive dataset highlighting age-related differences in behavior and gut microbiota among adult mice, contributing to a better characterization of normal aging processes.","41880677":"ID: 41880677\nTitle: Dietary N-acetylneuraminic acid maintains intestinal homeostasis and protects against aging- and inflammation-associated colonic dysfunction.\nAbstract: Intestinal homeostasis is essential for systemic health and longevity, and its disruption contributes to colitis and age-related gut dysfunction. N-acetylneuraminic acid (Neu5Ac), a major form of sialic acid enriched in bird's nest and human milk, exhibits immunomodulatory and antioxidant properties, yet its physiological role in intestinal integrity remains unclear. Here, we demonstrate that oral Neu5Ac supplementation preserves intestinal homeostasis in both natural aging and dextran sulfate sodium (DSS)-induced colitis models. Neu5Ac enhanced epithelial barrier integrity, increased tight-junction proteins, and maintained mucosal architecture. It alleviated systemic and local inflammation by suppressing macrophage infiltration and polarization toward the pro-inflammatory phenotype while maintaining tissue-reparative macrophages. Neu5Ac also selectively enriched butyrate-producing bacterial taxa, including Butyricimonas synergistica and Parabacteroides goldsteinii, thereby increasing fecal butyrate levels, without globally altering microbial diversity. Mechanistically, transcriptomic profiling implicated the HIF-1 signaling pathway in mediating the anti-inflammatory effects of Neu5Ac. Consistently, Neu5Ac reduced colonic HIF-1α protein signals, predominantly localized to inflammatory cells, and suppressed HIF-1α expression in LPS-stimulated macrophages. Neu5Ac promoted epithelial regeneration and mitigated senescence-associated p53 activation, thereby restoring gut homeostasis. Importantly, Neu5Ac exhibited excellent biosafety in vivo. Together, these findings identify Neu5Ac as a bioactive nutritional molecule that sustains intestinal homeostasis through coordinated epithelial, immune, and microbial modulation, offering a promising preventive strategy against aging- and inflammation-driven intestinal disorders.","41898153":"ID: 41898153\nTitle: Ayahuasca and Its Main Component N,N-Dimethyltryptamine (DMT) for the Treatment of Mental Disorders: Mechanisms of Action, Clinical Studies, and Tools to Explore the Human Mind.\nAbstract: In recent years, psychopharmacology has experienced a significant challenge, highlighting a renewed and strong scientific interest in psychedelics as breakthrough therapies for mental disorders. Psychedelics can influence cognitive and emotional processes, showing solid therapeutic potential, particularly in treatment-resistant psychiatric disorders. Amongst the most promising compounds, ayahuasca and its main psychoactive component, N,N-dimethyltryptamine (DMT), have received considerable attention. Ayahuasca is a psychoactive brew traditionally prepared from the liana Banisteriopsis caapi and the leaves of Psychotria viridis. Its psychoactive properties derive mainly from DMT, while β-carbolines, which act as monoamine oxidase-A (MAO-A) inhibitors, prevent the metabolic degradation of DMT, enhancing its bioavailability and allowing oral administration. In contrast, in monotherapy, DMT or its analog 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) is generally administered via alternative routes, like inhalation, intranasal, or intravenous delivery. DMT is primarily a serotonin (5-HT)2A receptor partial agonist, whereas 5-MeO-DMT has a higher affinity for the 5-HT1A receptor compared to 5-HT2A, though other receptor targets are engaged, fostering neuroplasticity and a reorganization of brain networks involved in perception, cognition, and mood regulation. Despite limited clinical trials, current evidence offers an optimistic outlook on DMT and 5-MeO-DMT efficacy for treatment-resistant depression (TRD) and major depressive disorder (MDD), whereas evidence for other mental disorders studies is still preliminary. There are four phase II studies with 5-MeO-DMT and one with DMT for TRD, while there are two phase II studies with DMT fumarate for MDD. Beyond their therapeutic potential, psychedelics also represent powerful tools for exploring the human mind, offering valuable insights into brain function and mental health.","41956455":"ID: 41956455\nTitle: Dietary Fiber in Sport: Implications for Performance and Body Composition Optimization.\nAbstract: Although dietary fiber is widely recognized for its health benefits in the general population, including reduced risk of cardiovascular disease and improved metabolic regulation, its role in athletic performance and recovery remains comparatively underexplored. Current sports nutrition guidelines lack specific recommendations for fiber intake, despite evidence linking adequate consumption to gut microbiome stability, immune modulation, and body composition optimization. Athletes face unique physiological demands that influence gastrointestinal tolerance, nutrient absorption, and energy availability, particularly under high training loads. Although excessive fiber intake may lead to gastrointestinal discomfort or reduced caloric intake, moderate and periodized consumption has been associated with enhanced immune function, improved energy metabolism, and preservation of skeletal muscle mass. Recent findings suggest potential benefits in attenuating exercise-induced inflammation and regulating substrate utilization. Nevertheless, observational data indicate that many athletes fail to meet general population intake targets, often due to precompetition dietary restrictions or concerns about digestive comfort. This review critically synthesizes current evidence on the physiological impacts of dietary fiber in athletic populations, focusing on gastrointestinal health, immune function, body composition, and performance outcomes. It further outlines practical, evidence-based strategies to optimize intake according to individual needs and sport-specific demands, including fiber periodization, source selection, and gradual adaptation.","41971338":"ID: 41971338\nTitle: A pilot study on spoilage dynamics in industrially produced Paneer Shahri, a traditional Iranian fresh cheese.\nAbstract: Paneer Shahri is a traditional Iranian fresh cheese with high moisture and near-neutral pH, making it susceptible to microbial spoilage. This study aimed to assess spoilage-related changes in Paneer Shahri during storage. Microbial, physicochemical, textural, and sensory changes in industrially produced, enzyme-coagulated Paneer Shahri were evaluated during cold storage (8 °C) over 34 days. Despite pasteurization, spoilage was primarily driven by non-starter lactic acid bacteria (NSLAB), including Lactococcus lactis, Enterococcus faecalis, and Lacticaseibacillus rhamnosus. These bacteria, all proteolytic and psychrotrophic, were consistently recovered throughout storage and became dominant members of the microbial community. Fermentation of residual lactose by LAB led to a significant decline in pH and an increase in titratable acidity, creating acidic conditions that further supported LAB persistence. Proteolysis contributed to texture softening, as reflected by declining chewiness, gumminess, springiness, and cohesiveness. Biogenic amine production by E. faecalis, particularly tyramine, was observed, posing a potential safety concern during prolonged storage. No Enterobacteriaceae, coagulase-positive staphylococci, or aerobic spore-formers were detected, and lipolysis remained negligible throughout the storage period. Yeasts and molds appeared only in the late stages of storage, and sensory analysis revealed declining smell and overall acceptability, consistent with microbial and biochemical spoilage markers. These findings highlight the metabolic activity and persistence of NSLAB as key drivers of spoilage in the absence of classical pathogens, emphasizing the importance of monitoring LAB activity to extend shelf life in fresh high-moisture cheeses.","41986862":"ID: 41986862\nTitle: Unravelling the Links Between Gastroesophageal Reflux and Lung Disease: New Insights.\nAbstract: Gastroesophageal reflux disease (GERD) is a prevalent comorbidity of chronic respiratory diseases including idiopathic pulmonary fibrosis (IPF), non-IPF interstitial lung disease, asthma, chronic obstructive pulmonary disease (COPD) and refractory chronic cough. Prevalence of symptoms of reflux and/ or refractory respiratory symptoms, along with concerns that refluxed gastric contents into the esophagus may micro-aspirate into the lungs causing injury and potentially accelerate disease progression, have resulted in high usage of empirical anti-reflux treatments. However, empirical treatment of reflux (medical or mechanical) is frequently ineffective without obvious explanation for the lack of respiratory improvement. This review provides novel and updated understanding of the pathophysiological mechanisms that link upper gut dysfunction, reflux (both distal and proximal), lung structure, lung mechanics and breathing patterns, including the potential role of the vagally mediated esophageal-bronchial reflex and the bi-directional nature of these interactions in individual respiratory diseases. We also highlight the need for a consensus between gastrointestinal and respiratory communities and propose a framework for diagnosing and managing GERD in respiratory disease.","41989616":"ID: 41989616\nTitle: Dietary unsaturated fatty acids distinctly associate with the early age sleep-wake cycle and gut integrity in aged fruit flies, Drosophila melanogaster.\nAbstract: Obesity is a risk factor for compromised health and a driver for non-communicable diseases. Effects of various fats on health, behavior, and other parameters have been studied using different model organisms, including fruit flies Drosophila melanogaster, by exposing them to dietary fats (saturated and trans fatty acids). However, the long-term and short-term effects of dietary unsaturated fatty acids (USFA) on physiology and sleep-activity behavior are relatively less explored. Hence, the present study hypothesizes that exposure to a USFA-rich diet differentially influences early-life behavioral traits and long-term fitness in fruit flies. The results of our study reveal that the flies exhibit attraction to USFA, with comparable responses to control and the higher doses. We further observed sexual dimorphism in lifespan, with males fed with low-dose (2.5%) and intermediate-dose (10%) USFA outliving females. Further, upon first-time examining the interaction between behavioral changes and fitness of flies fed with USFA, our results reveal that the females under MUFA increased late-night activity, and the female flies fed highest dose of MUFA (20%) exhibited sleep reorganization, by reduced sleep in nighttime and increased in daytime. Further, MUFA-fed flies enhance sleep fragmentation at an early age. In line at late age, flies fed with an intermediate dose of MUFA showed loose gut integrity (Smurf positive). Overall, this study suggests that USFA-fed flies have shorter survival associated with sleep fragmentation in early life and reduced gut integrity of flies at a late age in a sex and dose-dependent manner. Highlighting sleep fragmentation and gut dysfunction may contribute dietary USFA quality to aging-associated fitness.","41995884":"ID: 41995884\nTitle: Renalase knockdown inhibits proliferation of mouse satellite cells.\nAbstract: BACKGROUND: Skeletal muscle regeneration is mediated by skeletal muscle stem cells, known as satellite cells. Satellite cell proliferation is regulated by various secreted factors, including exercise-induced cytokines. Renalase is a protein that promotes cell proliferation through activation of intracellular signaling pathways in tumor cells. However, the role of renalase in satellite cell proliferation remains unclear. This study aimed to elucidate the role of renalase in satellite cell proliferation. METHODS AND RESULTS: Satellite cells were isolated from the extensor digitorum longus (EDL) muscles of male mice. Renalase expression was suppressed using an adenoviral vector expressing short hairpin RNA (shRNA). Renalase knockdown significantly suppressed cell numbers, particularly reducing the Pax7⁺/MyoD⁺ cell population. In addition, the numbers of Ki67-positive and EdU-positive cells were significantly reduced, and the expression of genes involved in cell-cycle progression was significantly decreased. Furthermore, the phosphorylation levels of ERK1/2 and Akt, key signaling molecules involved in cell proliferation, were significantly reduced following renalase knockdown. CONCLUSION: These results indicate that renalase is essential for satellite cell proliferation and that renalase knockdown inhibits satellite cell proliferation by suppressing the Akt–mTOR and ERK1/2 signaling pathways.","42003095":"ID: 42003095\nTitle: Metabolites and Polycystic Ovarian Syndrome: A Mendelian Randomization Study.\nAbstract: Polycystic ovarian syndrome (PCOS) is a common reproductive disorder that affects a considerable number of women worldwide. Nevertheless, the causal relationship between metabolites and PCOS remains undetermined. We utilized a comprehensive two-sample Mendelian randomization (MR) analysis, a genetic epidemiological approach that uses genetic variants as instrumental variables to assess causal relationships between exposures and outcomes, to examine the causal link between 1352 metabolites and PCOS. We employed complementary MR methods, such as the inverse-variance weighted (IVW) method, and conducted sensitivity analyses to evaluate the reliability of the outcomes. Reverse MR analysis was performed to evaluate the possibility of reverse causation. Five metabolites were identified to be significantly associated with PCOS risk: Methionine sulfoxide levels (IVW: OR [95%]: 1.549[1.274 to 1.883], p = 1.154E-5), Theophylline levels (IVW: OR [95%]: 0.725[0.589 to 0.890], p = 0.002), 4-hydroxycoumarin levels (IVW: OR [95%]: 0.786[0.658 to 0.940], p = 0.008), Tyramine O-sulfate levels (IVW: OR [95%]: 0.699[0.568 to 0.862], p = 0.0008), and Sulfate of piperine metabolite C16H19NO3 (3) levels (IVW: OR [95%]: 1.296[1.064 to 1.579], p = 0.009). We found PCOS was significantly associated with decreased Tyramine O-sulfate levels using the IVW method (OR [95%]: 0.953[0.917 to 0.991], p = 0.015) in the reverse MR analysis. The results of the sensitivity analyses were consistent with the main findings. This study establishes causal relationships between specific metabolites and PCOS, highlighting the significant roles of oxidative stress (methionine sulfoxide), dietary components (theophylline, piperine metabolite), and gut microbiome-derived metabolites. These findings provide novel insights into PCOS pathogenesis and identify potential targets for prevention and treatment. However, the study's limitation to European populations necessitates further validation in diverse ethnic groups. Our MR analysis provides strong evidence supporting a causal association between metabolites and the susceptibility of PCOS.","42015463":"ID: 42015463\nTitle: Sex Differences in Levodopa-Sparing Effect of Safinamide: Post-hoc Findings from a Multicenter, Longitudinal, Case-Control Study.\nAbstract: Female sex increases the risk of levodopa-induced dyskinesias in Parkinson's disease (PD). While levodopa-sparing effects of monoamine oxidase-B inhibitors (iMAO-B) are established, sex differences in response to safinamide remain unexplored. To evaluate sex differences in longitudinal (9 ± 3 months) changes in levodopa dose and total levodopa-equivalent daily dose (LEDD) with safinamide 100 mg. We included 259 PD patients treated with safinamide 100 mg (cases, n = 130) or never exposed to iMAO-B (controls, n = 129). The primary outcome was the sex × treatment interaction on the change in levodopa daily dose adjusted for body weight. Safinamide 100 mg improved UPDRS-III scores and reduced OFF-time independently of sex. A significant sex × treatment interaction emerged for change in weight-adjusted levodopa dose and total LEDD, with greater reduction in women (p = 0.025 and 0.045, respectively). Safinamide 100 mg provides a larger levodopa-sparing effect in women, supporting sex-specific optimization of dopaminergic therapy in PD management.","42022562":"ID: 42022562\nTitle: Selegiline, a monoamine oxidase-B inhibitor as a modulator of metabolic reprogramming for cancer therapy: a review.\nAbstract: Metabolic reprogramming plays a crucial role in cancer progression, therapeutic resistance, and tumor-microenvironment remodelling. Monoamine oxidase-B (MAO-B), a mitochondrial enzyme involved in oxidative deamination, has recently been identified as a metabolic regulator that influences reactive oxygen species (ROS) production, mitochondrial homeostasis, and redox-dependent signaling in tumors. Selegiline, an MAO-B inhibitor traditionally used in neurological disorders, is now gaining attention for its potential role in modulating tumor metabolism. Elevated MAO-B activity contributes to oxidative stress, genomic instability, immune suppression, and metabolic adaptations that support tumor survival. By inhibiting MAO-B, selegiline reduces ROS generation, alters mitochondrial respiration, regulates glycolytic flux, and disrupts hypoxia-associated pathways, making it a promising modulator of metabolic checkpoints in oncology. Relevant literature was collected from PubMed, Google Scholar, and ScienceDirect using keywords such as Selegiline, MAO-B inhibitor, tumor metabolism, oxidative stress, and drug repurposing in cancer. Relevant studies from the past 5 years, with inclusion criteria focusing on mechanistic, preclinical, and translational evidence related to MAO-B and selegiline-mediated metabolic regulation. Recent findings indicate that selegiline not only modulates cancer cell metabolism but also influences the tumor microenvironment by reducing inflammatory cytokine production, altering macrophage polarization, and enhancing susceptibility to therapeutic stress. Additionally, combination approaches with chemotherapeutics, metabolic inhibitors, and immunotherapies show synergistic potential. This review summarizes current insights into selegiline's role in metabolic reprogramming, highlights existing challenges, and discusses future opportunities for repositioning selegiline as a targeted metabolic modulator in cancer therapy.","42042907":"ID: 42042907\nTitle: Effects of Probiotic Supplementation on Gut Microbiota and Fecal Metabolome in Autism Spectrum Disorders: A Secondary Analysis of a Randomized Clinical Trial in Preschoolers.\nAbstract: Recently, a randomized clinical trial evaluated whether a six-month probiotic administration could reduce symptom severity in preschool children with Autism Spectrum Disorders (ASD), with (GI) or without (NGI) gastrointestinal symptoms. Significant positive changes were observed only in NGI children. A second explorative study on children prior to intervention identified a fecal metabolome fingerprint associated with ASD severity. Building on these findings, the present study aimed to assess whether metabolomics could monitor changes in ASD severity following probiotic administration using a subset of samples from the same trial. Second, this study aimed to identify fecal metabolites to be monitored in children to predict whether their autism severity may decrease after probiotic or placebo treatment. Evaluations of the fecal metabolome and microbiota could be completed on 57 children before and after a double-blind administration of a probiotic mixture or a placebo. In NGI children the probiotic was found to influence the concentration of the amino acids aspartate, leucine, tryptophan, and valine, together with nicotinate and the short chain fatty acids acetate, butyrate, isobutyrate, and propionate. Lactobacilli and Sutterella showed significant changes in response to probiotic administration (p < 0.05). Acetate, 4-hydroxyphenyl, galactose, proline, and tyramine were identified as key fecal metabolites for prediction purposes. The present exploratory analysis, despite the small sample size, suggests that fecal metabolomics may provide a useful approach for monitoring and potentially for predicting changes in ASD severity following probiotics administration.","42051732":"ID: 42051732\nTitle: Source-stratified gut-extraintestinal organ crosstalk in sepsis-associated acute gastrointestinal injury and paralytic ileus: the gut as both driver and target.\nAbstract: Sepsis-associated acute gastrointestinal injury and paralytic ileus are common but underrecognized manifestations of systemic critical illness and are closely linked to feeding intolerance, barrier failure, secondary infection, and progression to multiorgan dysfunction. However, the gut in sepsis should not be viewed solely as a passive target of distant organ injury. Owing to its unique microbial burden, highly specialized epithelial-immune barrier, and central role in host-microbe and metabolic homeostasis, the gut may function either as an initiator of injury amplification or as a vulnerable downstream target, depending on the infectious source and disease stage. In this review, we propose a source-stratified framework for gut-extraintestinal organ crosstalk in sepsis-associated acute gastrointestinal injury and paralytic ileus. In enterogenic sepsis, the gut more commonly serves as an injury driver through barrier disruption, microbial translocation, dysbiosis, and propagation of inflammatory and metabolic stress signals. In extraintestinal sepsis, the gut more often emerges as a susceptible target of systemic inflammation, microcirculatory failure, neurohumoral dysregulation, and organ-to-organ injury transmission, while subsequent gut dysfunction may in turn amplify remote organ damage. These distinct starting points ultimately converge into a self-reinforcing loop involving epithelial and endothelial barrier failure, immune dysregulation, mitochondrial dysfunction, immunometabolic reprogramming, regulated cell death, extracellular vesicle-mediated signaling, and bidirectional organ injury amplification. We further summarize how these shared mechanisms shape the gut-lung, gut-brain, gut-liver, gut-kidney, and gut-heart axes, and discuss their implications for biomarker development, bedside phenotyping, source-based risk stratification, and mechanism-guided therapeutic strategies. By reframing the gut as both driver and target within a source-dependent network of organ crosstalk, this review aims to provide a more integrative pathobiological model for sepsis-associated gastrointestinal dysfunction and to inform future translational and clinical studies.","42061249":"ID: 42061249\nTitle: Gut health in broiler chickens fed a mixture of Hermetia illucens and Tenebrio molitor meals: does it have a key role in shaping bird performance?\nAbstract: Insect meals are promising sustainable protein sources for poultry, but comprehensive insights into their effects on gut health and growth performance are lacking. This study is the first to elucidate relationships between gut health parameters and performance in broilers fed Hermetia illucens (HI) and Tenebrio molitor (TM) meals at 5% or 10% inclusion levels, singly or in a 1:1 combination. A 37-day trial used 420 male Ross 308 chicks randomly allocated to seven treatments: control (C), HI5 (5% HI), HI10 (10% HI), TM5 (5% TM), TM10 (10% TM), MIX5 (5% MIX), and MIX10 (10% MIX). By integrating intestinal histomorphometry, mucin histochemistry, multi-organ histopathology, and multi-omics cecal microbiome characterization, we identified key structural, microbial, and metabolic biomarkers associated with performance variations (false discovery rate [FDR]<0.05 and P < 0.05 for microbiome and histomorphology, respectively). High-performing groups (MIX5, TM5) showed microbiomes enriched in short-chain fatty acid-producing bacteria (Veillonellaceae, Butyricicoccus, Limosilactobacillus crispatus), positively correlated with ADG and ADFI (FDR<0.05) and negatively correlated with FCR (FDR<0.05). Favorable metabolomic profiles (increased dopamine, tyramine, malic and orotic acids; reduced 3-deoxyglucosone, hexanoylcarnitine [FDR<0.05]) and preserved balance between neutral (positively correlated with BW and ADFI [P < 0.05]) and acidic mucins (positively correlated with BW, ADFI and ADG, and negatively correlated with FCR [P < 0.05]) were also observed. Low-performing groups (MIX10, HI10) displayed microbiomes dominated by Ruminococcaceae, Alistipes, and l-Eubacterium (negatively correlated with FCR and associated with purine metabolism alterations [FDR<0.05]), alongside worsened morphology (tendency for reduced villus height in MIX10 [P = 0.07], positively and negatively correlated with ADG and FCR, respectively [P < 0.05], and thinner mucosal/muscular layers [P < 0.05]) and decreased neutral mucins (P < 0.05). TM10 maintained unaffected growth performance via beneficial taxa (Limosilactobacillus crispatus, Tyzzerella), and reduced Campylobacter jejuni and antimicrobial resistance genes (FDR<0.05). Jejunal inflammation, negatively correlated with ADG (P < 0.05), was not influenced by dietary treatments (P > 0.05). In conclusion, specific taxa (Butyricicoccus, Veillonellaceae, Limosilactobacillus crispatus), metabolites (dopamine, tyramine, malic and orotic acids), and mucosal features (villus height, mucin composition) were identified as biomarkers of optimal performance in insect-fed broilers.","42073336":"ID: 42073336\nTitle: A Fluorescent Composite of Carbon-Dot-Embedded Covalent Organic Frameworks for Highly Sensitive and Rapid Detection of Biogenic Amines in Large Yellow Croaker.\nAbstract: The excessive accumulation of biogenic amines (BAs) in aquatic products poses serious health risks, necessitating the development of rapid and sensitive detection methods. This study reports the synthesis of a novel fluorescent nanocomposite, carbon-dot-embedded covalent organic frameworks (CDs@COFs). Comprehensive characterization (TEM, XPS, FTIR, UV-Vis, and fluorescence spectroscopy) confirmed the successful fabrication of the nanocomposites, which exhibited excellent thermal and optical stability. A significantly enhanced quantum yield of 36.22% (compared with 12.92% for pure carbon dots) was obtained. As a fluorescent probe, the composite enabled the detection of nine BAs based on a fluorescence quenching mechanism. The proposed method demonstrated good linearity (1~100 ng/mL) and low detection limits of 0.58~0.98 ng/mL. The method was successfully applied to analyze tyramine in large yellow croaker, showing accurate spike recoveries ranging from 91.93% to 101.43% and excellent reproducibility (RSD < 3%). These results highlight the great potential of the developed method as a powerful tool for the rapid screening of BAs in aquatic products.","42083198":"ID: 42083198\nTitle: Squid cartilage-derived chondroitin sulfate from Uroteuthis chinensis: a novel marine prebiotic modulating gut microbiota and ameliorating ulcerative colitis.\nAbstract: This study evaluated the prebiotic potential of chondroitin sulfate (CS) derived from the cartilage of the squid Uroteuthis chinensis, and its protective effects against dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) in mice. Dietary intervention with squid-derived CS significantly attenuated characteristic UC symptoms, including body weight loss, colon shortening, and histopathological damage. Mechanistic analyses revealed that squid-derived CS exerted potent anti-inflammatory effects by downregulating key pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) and alleviated oxidative stress by enhancing colonic antioxidant capacity, as evidenced by increased activities of catalase (CAT) and superoxide dismutase (SOD) and reduced myeloperoxidase (MPO) activity. Integrated 16S rRNA gene sequencing and metabolomics analyses demonstrated that squid-derived CS profoundly restructured gut microbial community composition by enriching putative beneficial bacteria (e.g., Bifidobacterium, Clostridium, Blautia) while reducing opportunistic pathogens (e.g., Enterococcus, Sutterellaceae, Clostridia_UCG-014). This favorable microbial shift was accompanied by a reconfiguration of the intestinal metabolome, characterized by elevated production of beneficial short-chain fatty acids (SCFAs) and decreased levels of pro-inflammatory metabolites such as tyramine. Furthermore, squid-derived CS effectively enhanced intestinal barrier integrity by upregulating key tight junction proteins (ZO-1, occludin, claudin-1), thereby preventing bacterial lipopolysaccharide (LPS) translocation and associated liver injury, as indicated by reduced serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Collectively, these findings demonstrate that dietary squid-derived CS protects against UC by modulating gut microbiota composition to enrich beneficial taxa, restoring microbial metabolite homeostasis, reinforcing the intestinal epithelial barrier, and suppressing inflammatory responses and oxidative stress. This study provides the first evidence that squid-derived CS acts as a novel and promising marine prebiotic candidate for gut health promotion, highlighting its potential as a sustainable functional ingredient derived from processing waste for gut-health-promoting foods.","42092952":"ID: 42092952\nTitle: Multi-omics analysis of deep brain stimulation associated with brain-gut axis modulation and symptom amelioration in a Parkinson's disease mouse model.\nAbstract: This study aimed to systematically elucidate the molecular mechanisms underlying PD-associated brain-gut dysfunction through multi-omics analyses and to evaluate the therapeutic potential of combined Deep Brain Stimulation (DBS) and Brain-Computer Interface (BCI) interventions. Transcriptomic and 16S rRNA datasets from Gene Expression Omnibus (GEO) and Sequence Read Archive (SRA) were integrated and analyzed using DESeq2, limma, Gene Set Enrichment Analysis (GSEA), and PICRUSt2 to identify disrupted pathways and microbial functional features. In the 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD mouse model, four groups (Normal, MPTP, MPTP + DBS, and MPTP + DBS+BCI) were assessed using behavioral testing, Local Field Potentials (LFP) recordings, molecular assays, and histological analysis. The findings revealed synaptic damage and metabolic pathway disruptions in PD brains, accompanied by reduced abundance of Short-Chain Fatty Acid (SCFA)-producing gut microbes. Combined DBS and BCI markedly improved motor deficits, suppressed aberrant β oscillations, restored gut barrier integrity and microbial homeostasis, and reduced pathological α-synuclein (αSyn) aggregation. Collectively, these results demonstrate that DBS + BCI is associated with improvements across neural, microbial and inflammatory readouts, supporting a correlative brain-gut-immune framework.","42115271":"ID: 42115271\nTitle: Altered gut microbiota and metabolites in children with non-organic anorexia: a multi-omics integration study.\nAbstract: Gut microbiota alterations have been linked to childhood eating disorders, but the functional and metabolic changes in non-organic anorexia (NOA) remain poorly understood. This study aimed to characterize the gut microbial composition, function, and metabolic profiles in children with NOA using an integrated multi-omics approach. A case-control study was conducted involving 88 children aged 1-5 years (48 NOA, 40 healthy controls). Gut microbiota composition was assessed via 16S rRNA gene sequencing of all fecal samples. Subsequently, the five most representative samples from each group were selected for deep shotgun metagenomic sequencing and liquid chromatography-mass spectrometry (LC-MS) based non-targeted metabolomics. NOA children showed significantly higher microbial richness and diversity (Chao1, Shannon; P < 0.001). The NOA group had elevated Firmicutes, Bacteroidota, Bacteroides, Faecalibacterium, Subdoligranulum, and Roseburia, but reduced Actobacteriota, Bifidobacterium, and Enterococcus. Metagenomics revealed downregulated riboflavin metabolism and upregulated fat digestion/absorption pathways in NOA (P < 0.05). Metabolomics identified 26 differential fecal metabolites, including decreased L-carnitine derivatives and elevated tyramine glucuronide involved in bile secretion. These metabolites were significantly correlated with altered bacterial genera. Our integrated multi-omics analysis demonstrates that NOA in children is associated with a specific gut ecosystem characterized by altered microbiota structure, perturbed microbial metabolic functions (particularly riboflavin metabolism), and corresponding host-microbiota co-metabolic disturbances. These findings provide novel evidence for the disrupted \"microbiota-metabolite\" axis in NOA, offering new mechanistic insights.","42123770":"ID: 42123770\nTitle: Bioactive Compounds in Coffee: Metabolism, Bioavailability and Health Effects-A Review.\nAbstract: Coffee is a very popular psychoactive beverage with a complex composition. Besides its stimulant effect due to caffeine, it contains several bioactive compounds with antioxidant properties and potent metabolic activity. Its clinical efficacy is fundamentally determined by the bioavailability and metabolic fate of its constituents. The bioactive components of coffee, such as polyphenols, melanoidins, phytosterols, biogenic amines, and carotenoids, have notable antioxidant, anti-inflammatory, and immunomodulatory effects. This review aims to present the main bioactive components of coffee, their biological effects, mechanisms of action, and the influence of preparation methods and individual variability on metabolic outcomes in common chronic diseases. The data are synthesized from clinical, prospective, and interventional studies to examine how processing variables and biological metabolism influence the health-promoting potential of coffee antioxidants. Brewing methods like hot filtration optimize the extraction of these antioxidants. Individual clinical outcomes are further modulated by genetic polymorphisms and gut microbiota variability, which influence the activation of the cellular Nrf2 antioxidant defense pathway.","42128191":"ID: 42128191\nTitle: Phenethylamines in pre-workout supplements alter arterial pressure, heart rate, and body temperature in rats.\nAbstract: Phenethylamine (PEA) and its analogues are frequently present in pre-workout and weight loss food supplements and share structural similarity with amphetamine and the endogenous catecholamines (nor)adrenaline and dopamine, suggesting potential sympathomimetic activity. Multiple adverse cardiovascular events have been associated with the use of food supplements containing these ingredients, while knowledge of the underlying pharmacology and toxicology of such food supplements and their ingredients remains limited. Therefore, the aim of the current study was to investigate the acute cardiovascular effects of a selection of PEAs in conscious rats. Heart rate (HR), arterial pressure (AP) and body temperature were continuously, and wirelessly, monitored using pressure telemetry in Wistar-Kyoto rats that were intravenously exposed to cumulative doses of PEA and seven commonly used analogues: BMPEA, halostachine, higenamine, isopropyloctopamine, p-octopamine, p-synephrine and p-tyramine. All PEAs, except PEA itself and BMPEA, significantly altered AP with maximal absolute increases between 65 and 103 mmHg. Maximal absolute increases in HR induced by higenamine and isopropyloctopamine were found to be 110 and 123 beats per minute, respectively. The PEA analogues BMPEA, p-octopamine, halostachine and p-synephrine, instantly lead to reduced body temperatures, ranging from minus 0.5 to minus 1.5 °C. This study demonstrates that several PEAs, exert pronounced and rapid effects on AP, HR and body temperature in rats. The magnitudes of these effects were similar to or even higher than the cardiovascular changes induced by adrenaline, suggesting that combining these substances with physical exercise may amplify sympathetic load and pose a serious health risk, particularly for individuals with underlying cardiovascular vulnerabilities.","42129938":"ID: 42129938\nTitle: Multi-omics reveals effects of several rumen bacteria on reproductive performance of sheep.\nAbstract: Mounting evidence indicates that the rumen microbiota plays a crucial role in the reproductive health of sheep. However, the potential beneficial effects of rumen microbiota on lambing performance in sheep across different stages of the reproductive cycle and the precise mechanisms underlying these effects remain unclear. We aimed to elucidate the rumen microbial regulatory network underlying differences in reproductive performance in sheep by integrating multi-stage metagenomics and metabolomics. No significant difference was observed in the ruminal microbial α-diversity between sheep with high and low litter size. However, significant stage-specific segregation was observed in their community structures. We identified a cohort of key species strongly associated with litter size. These included Asaia bogorensis, Methanolobus zinderi, Erwinia gerundensis, Marinobacter sp. BSs20148, and Lactobacillus amylolyticus enriched during pregnancy; Rhizobium gallicum, Aeromonas caviae, Pseudolysobacter antarcticus, Mucilaginibacter rubeus, Thermococcus paralvinellae, and Janthinobacterium svalbardensis enriched during lactation; Pseudomonas mandelii, Gordonia sp. HY186, Arachidicoccus sp. BS20, Mesotoga prima, Acidovorax ebreus, Donacia cinerea, and Salmonella enterica enriched during estrus. Host plasma metabolomics analysis further revealed an enrichment of a set of core metabolites in the blood of high-fertility sheep, including Inositol, 2-Linoleoylglycerol, lysophosphatidylcholines and neuromodulatory substances such as tyramine and sphingosine-1-phosphate. We constructed stage-specific \"rumen microbe-rumen metabolite-plasma metabolite\" regulatory axes. These results suggest the influence of the rumen microbiome on plasma metabolic profiles and subsequent fertility outcomes in sheep. We elucidate the dynamic mechanism by which the rumen microbiota in high-fertility sheep is associated with superior reproductive performance through stage-adaptive community succession and functional remodeling, which in turn may modulate the host's neuroendocrine and lipid metabolic profiles. These findings provide a new perspective for understanding the regulation of fertility in ruminants and lay a theoretical foundation for improving reproductive efficiency through nutritional strategies targeting the rumen microbiota.

This review outlines their activation of the brainstem's area postrema (AP) via intestinal barrier disruption, dysbiosis, vagus nerve stimulation, or direct central penetration. Acute exposure induces anorexia/defense responses through AP/NTS receptor pathways (GLP-1R, CCK, PYY, ghrelin, GDF15-GFRAL, 5-HT3). Chronic exposure impairs the AP-hypothalamus-locus coeruleus (LC) pathway, causing neuropsychiatric disorders, cachexia-like metabolic reprogramming, and multi-organ dysfunction. The gut microbiota play pivotal roles in toxin metabolism, bioactivation, and detoxification; microbial dysbiosis and LPS translocation amplify systemic inflammation. The elderly, immunocompromised individuals, and patients with comorbidities are particularly vulnerable due to weakened barriers, immunosenescence, and polypharmacy. This review elucidates the toxin-induced acute-to-chronic cascade via the gut-brain-neuro-metabolic network, discusses current limitations and future directions, and provides a theoretical basis for understanding chronic pathogenic mechanisms and complex comorbidities.","42153897":"ID: 42153897\nTitle: Phosphate binders and the gut microbiota in chronic kidney disease: mechanisms, mixed evidence, and clinical considerations.\nAbstract: Chronic kidney disease (CKD) disrupts the gut microbiome through dietary restrictions, uraemia, and polypharmacy, including phosphate binders. This dysbiosis contributes to systemic inflammation, accumulation of uremic toxins, and reduced short-chain fatty acid (SCFA)-producing bacteria. Hyperphosphatemia, a key CKD complication, typically emerges in advanced stages. This review examines the impact of phosphate binders on gut microbiota and explores emerging biological therapies. Phosphate binders are standard treatment for hyperphosphatemia but may influence gut microbiota by altering luminal pH, intestinal transit, and availability of metabolites such as SCFAs and vitamin K. These changes can impair gut barrier integrity and promote inflammation. Evidence on their microbiome effects is mixed: some studies show minimal compositional changes with calcium acetate or sucroferric oxyhydroxide, while others report individual variability and subtle taxon-specific shifts, particularly with iron-based binders. Even when compositional changes are limited, certain binders may modulate uremic toxin levels. Given the limitations of conventional therapies, biological approaches such as probiotics, synbiotics, and phosphate-accumulating organisms (PAOs) are gaining interest. These strategies may reduce intestinal phosphate availability by lowering pH, enhancing calcium-phosphate binding, and promoting microbial phosphate uptake and storage, while supporting gut barrier function. Overall, current evidence remains heterogeneous and limited by small cohorts and preclinical designs. Although microbiota-targeted therapies show mechanistic promise, robust clinical trials are needed before they can be recommended beyond adjunctive use.","42158814":"ID: 42158814\nTitle: The Effects of a Prebiotic Formula Promoting Akkermansia muciniphila (AKK) on Gut Health: A Single-Centre, Randomised Controlled Trial.\nAbstract: Gut health is closely associated with metabolic homeostasis, and alterations in gut microbiota composition have been linked to inflammation and metabolic disorders. Prebiotics targeting specific taxa, such as Akkermansia muciniphila, have attracted interest for their potential to modulate gut microbiota composition. While preclinical studies have suggested a role for A. muciniphila in gut-related metabolic pathways, clinical evidence supporting its effects on microbiome regulation and metabolic outcomes remains limited. Therefore, this study aimed to explore the effects of a prebiotic blend designed to promote A. muciniphila on gut microbiota composition and selected physiological parameters. Seventy participants were randomized to receive either placebo or the AKK formula for 8 weeks. Anthropometric assessments, blood tests, and stool examinations were performed at baseline and at weeks 4 and 8. The main analyses were conducted in the per-protocol population (n = 25 per group). The results revealed no significant markers of liver or kidney dysfunction in either group. The AKK formula group showed an increased qPCR-derived relative abundance of A. muciniphila compared with total bacteria. Gut microbiome analysis further demonstrated selective changes in gut microbiota composition in the AKK formula group, including an increased relative abundance of Bifidobacterium and decreased relative abundances of Proteobacteria, Erysipelotrichia, and Escherichia-Shigella. A trend toward lower gastrointestinal discomfort scores was observed in the AKK formula group during the intervention period. The AKK formula increased the relative abundance of A. muciniphila, was associated with selective modulation of gut microbiota composition, and showed a trend toward reduced gastrointestinal discomfort, supporting its potential relevance in future gut health research.","42162614":"ID: 42162614\nTitle: Effects of a pulse-based, guidelines-aligned diet on biomarkers relevant to aging: Results from the PRODMED1 randomized controlled crossover feeding trial.\nAbstract: Pulse-based diets are naturally low in methionine, an amino acid whose restriction has been linked to improved metabolic health and longevity. This study evaluated how a pulse-protein diet (PPD), relative to a meat-protein diet (MPD), both aligned with the Dietary Guidelines for Americans (DGA), influenced cardiometabolic and iron-related biomarkers relevant to aging in older adults. This Protein-Distinct Macronutrient-Equivalent Diet 1 (PRODMED1) trial was conducted among Midwestern adults aged ≥60 years. Participants consumed MPD and PPD for eight weeks each, separated by ≥ 2-week washout. Primary protein sources (162 g/d lean pork vs. 331.6 g/d pulses) contributed ≥45% of total dietary protein. Diets were matched for total iron, energy, and macronutrients but differed in heme iron and methionine. Primary outcomes were ferritin, fasting blood glucose, and trimethylamine N-oxide (TMAO); secondary outcomes included inflammation, body composition, lipid-related cardiovascular risk biomarkers, and circulating biogenic amines. Analyses were conducted using robust linear mixed-effects models, adjusted for covariates. Forty-seven participants completed the trial (72% women; age 69.2 ± 6.6 years; BMI 28.6 ± 5.4 kg/m2). Regardless of protein source, both diets improved biomarkers of glucose and lipid metabolism except HDL (all, p < 0.05; no between-diet differences), while TMAO remained unchanged. Total and visceral fat mass declined (both, p < 0.0001; no between-diet differences), with a greater reduction in the visceral-to-total fat ratio during PPD vs. MPD (p < 0.05). PPD demonstrated a larger increase in ferritin relative to MPD (PPD: +15.7 ng/mL vs. MPD: +7.0 ng/mL; between-diet p = 0.027), and CRP decreased in both groups (both, p ≤ 0.001, no between-diet differences). MPD and PPD resulted in distinct circulating biogenic amine profiles (p = 0.001). High-quality DGA-aligned diets improved cardiovascular risk factors irrespective of primary protein sources, underscoring the importance of overall dietary-matrix quality. However, the pulse-based diet conferred additional benefits to visceral-to-total fat ratio and iron status, supporting pulses as a feasible, nutrient-dense, and effective dietary strategy with potential relevance for promoting healthspan in aging populations. The trial is registered at www. gov as NCT05577858 on October 11, 2022.","42167203":"ID: 42167203\nTitle: Impact of Asymptomatic Enteroaggregative Escherichia coli Infection and Co-Pathogen Burden on Intestinal Barrier Function, Linear Growth, and Cognitive Development in Early Childhood: Insights from a Birth Cohort Study.\nAbstract: Enteroaggregative Escherichia coli (EAEC) is a major enteric pathogen in low-resource settings. The aim for the present study is to reanalyze the effects of subclinical EAEC infection, alone or in combination with other pathogens, on intestinal function, growth, and cognition in children aged 0-6 months through molecular diagnosis. A total of 1,659 non-diarrheal stool samples from the Etiology, Risk Factors and Interactions of Enteric Infections and Malnutrition and the Consequences for Child Health and Development cohort were analyzed using quantitative polymerase chain reaction testing for 29 enteropathogens. Children were grouped by infection status: EAEC alone or with 1, 2, or ≥3 co-pathogens. Enteroaggregative Escherichia coli and a higher pathogen burden were associated with lower socioeconomic status and greater antibiotic use (P <0.001). Enteroaggregative Escherichia coli with ≥3 co-pathogens was linked to elevated neopterin (β = 687.5; CI: 129.7-1,245.3), increased intestinal permeability (β = 0.41; CI: 0.058-0.77), and a lower length-for-age z-score (β = -0.44; CI: -0.76 to -0.12), and EAEC alone reduced cognitive scores at 15 and 24 months of age (β = -2.82 and -5.02, respectively; CI: -5.15 to -0.48 and -9.81 to -0.22, respectively). Subclinical EAEC infection is associated with inflammation, gut dysfunction, growth failure, and cognitive delay.","42184066":"ID: 42184066\nTitle: Green tea polyphenol-iron oxide chitosan nanoparticles modulate gut microbiota and regulate metabolic pathways.\nAbstract: Green tea polyphenols (GTPP) exhibit antioxidants, anti-inflammatory, and anticancer properties; however, their poor bioavailability limits clinical translation. Nanoparticle-based formulations may enhance absorption and therapeutic potential. This study investigates the therapeutic effects of GTPP encapsulated in iron oxide chitosan nanoparticles (GTPP-IOCHNP) on gut microbiota and hepatic proteome, with particular attention to pathways relevant to inflammation, drug metabolism, and tumorigenesis. Male Sprague Dawley rats were administered a single oral dose of GTPP or GTPP-IOCHNP (200 mg/kg). Cecal microbiota composition was analyzed by metagenomic sequencing, while liver proteome alterations were assessed using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Metagenomic analysis revealed that GTPP-IOCHNP promoted Actinobacteriota and Collinsella, both linked to reduced inflammation and improved gut health, while inhibiting Bacteroides and Ruminococcus genera associated with intestinal barrier dysfunction, inflammation, and nephropathy. Blautia was significantly enriched (p < 0.05), supporting short chain fatty acid production, modulation of lipid and carbohydrate metabolism, and transformation of polyphenols into bioactive antioxidant metabolites. Proteomics profiling identified 20 differentially expressed hepatic proteins (p < 0.05). GTPP-IOCHNP significantly downregulated cytochrome P4502D26 (CYP2D6), indicating modulation of CYP2D6 mediated drug metabolism, and suppressed glutamate dehydrogenase 1, implicating inhibition of glutamine-driven energy metabolism linked to cancer and hyperinsulinism. Conversely, significant upregulation of elongation factor 1-alpha-1 (eEF1A1), albumin, and adenosine kinase (ADK) highlighted improved GTPP absorption, systemic transport, and regulation of hepatic energy metabolism. The integrative metagenomic and proteomic analyses reveal that GTPP-IOCHNP improves polyphenol bioavailability by modulating gut microbial ecology and hepatic metabolic pathways, offering a mechanistically driven platform for therapeutic advancement.","42185771":"ID: 42185771\nTitle: Probiotic characterization of Lactobacillus helveticus BGTRM7-58 from Khiki cheese: safety, antimicrobial activity, antioxidant capacity, and anti-biofilm effects against Staphylococcus aureus.\nAbstract: Traditional Iranian cheeses, especially \"Khiki cheese,\" represent valuable sources of indigenous lactic acid bacteria with potential probiotic properties. This study evaluated the probiotic attributes, safety profile, antimicrobial efficacy, antioxidant capacity, and anti-biofilm activity of Lactobacillus helveticus BGTRM7-58, a strain isolated from Khiki cheese. The strain demonstrated considerable anti-adhesion capability against Staphylococcus aureus. The cell-free supernatant (CFS) exhibited potent antimicrobial activity, displaying a minimum inhibitory concentration (MIC) of 15.625 mg/mL against S. aureus. Furthermore, the CFS inhibited biofilm formation by 87% at 4× MIC and disrupted pre-established mature biofilms by 89% at the same concentration. In vitro cytotoxicity assessment revealed dose-dependent antiproliferative effects against cancer cell lines. Quantitative real-time PCR analysis indicated significant downregulation of key staphylococcal virulence genes, most notably a 47% reduction in agr expression. The strain also exhibited substantial antioxidant activity, scavenging 68.67%, 71.75% of DPPH and ABTS radicals, respectively. Comprehensive safety evaluation confirmed the absence of hemolytic and DNase activities, no production of biogenic amines, and susceptibility to clinically relevant antibiotics. Taken together, these findings indicate that L. helveticus BGTRM7-58 fulfills the fundamental criteria for a safe and functional probiotic strain, highlighting its potential for application in functional food formulations and strategies aimed at controlling biofilm-associated infections.","42206286":"ID: 42206286\nTitle: Dynamics of enzyme and metabolic profile of broilers fed black soldier fly (Hermetiailucens) larvae-based diets.\nAbstract: This study investigated the impact of replacing fishmeal with black soldier fly larvae meal (BSFLM) on growth performance, microbial enzyme activity, and metabolic functions in broiler chickens. A total of fifty Arbor Acre Plus chicks were distributed across five dietary groups, including a control (100% fishmeal) and four diets containing increasing levels of BSFLM (25%, 50%, 75%, and 100%) in a completely randomized design. Broilers were reared over eight weeks, and cecal samples were subjected to 16S rRNA metagenomic sequencing to profile gut microbial enzyme activities and metabolic functions. Results revealed a progressive increase in microbial enzyme abundance and functional metabolic pathways with higher BSFLM inclusion, particularly in the 50% (T3) and 100% (T5) groups. Key enzymes, including ABC-2-type ATP-binding proteins, RNA polymerase sigma factors, and carbohydrate-active enzymes, were significantly upregulated, supporting enhanced carbohydrate fermentation, amino acid biosynthesis, and central carbon metabolism. Metabolic pathway analysis indicated a dietary shift from carbohydrate-driven fermentation in the control group to a more protein- and lipid-centered metabolism in BSFL-fed birds, with T3 showing a balanced metabolic profile and T5 exhibiting hyper-metabolic activity. These findings demonstrate that BSFLM can replace fishmeal without compromising gut health and may even enhance microbial functionality, with a 50% replacement emerging as an optimal inclusion level to sustain balanced microbial metabolism.","42214261":"ID: 42214261\nTitle: Nano-selenium mitigates lead nanoparticle-induced hеpatonеural toxicity and growth performance in quails: Oxidative stress, neurotransmitter and anti-inflammatory response modulation.\nAbstract: Lead nanoparticles pose a significant threat to avian health, disrupting growth, inducing oxidative stress, and impairing neurological function. This study investigated the protective mechanisms of nano-selenium (Nano-Se) against lead oxide nanoparticles (PbNPs)-induced toxicity in Japanese quails (Coturnix coturnix japonica) using a controlled 28-day experimental design. A total of 360 two-week-old quails were randomly assigned to six treatment groups: (1) control (basal diet), (2) Nano-Se (0.2 mg/kg diet), (3) PbNPs-0.25 (0.25 µg/ml in drinking water), (4) PbNPs-0.50 (0.50 µg/ml), (5) Nano-Se + PbNPs-0.25, and (6) Nano-Se + PbNPs-0.50. Histopathological examination revealed dose-dependent hepatocellular necrosis (60-70% of hepatocytes in the high-dose group), vacuolar degeneration, sinusoidal congestion, and widespread neuronal degeneration with prominent satellitosis and neuronophagia. Immunohistochemical analysis confirmed TNF-α-driven neuroinflammation, with intense immunoreactivity in 50-55% of cortical neurons and 65-70% of hepatocytes in PbNPs-exposed groups (3.5-fold increase over controls). These structural lesions were accompanied by a dose-dependent redox crisis, depleting hepatic and neural glutathione S-transferase (GST) activity by 40-50% and elevating lipid peroxidation (MDA 2.5-fold), which correlated with neurotransmitter disruption (serotonin 35%, noradrenaline 45%, acetylcholinesterase 60% reduction) and hepatocyte damage (ALT/AST 3-fold elevation). Remarkably, Nano-Se co-administration attenuated toxicity via three synergistic mechanisms: Nrf2-mediated GST restoration, monoamine oxidase inhibition preserving neurotransmitter balance, and NF-κB suppression reducing Kupffer cell infiltration by 65%, with histopathological protection reducing necrosis incidence by 40-50% and suppressing neuroinflammatory TNF-α expression by 70-90%. Our findings demonstrate Nano-Se's multi-target efficacy against PbNPs toxicity mediated through selenoprotein-dependent and independent mechanisms, highlighting its potential as a nano-antidote for environmental heavy metal exposure.","42216074":"ID: 42216074\nTitle: Dietary baicalin supplementation enhances growth performance in fattening Hu sheep via dual modulation of immunity and gastrointestinal microbiome-metabolic crosstalk.\nAbstract: Baicalin is a bioactive flavonoid from Scutellaria baicalensis Georgi with antioxidant, anti‑inflammatory and antibacterial properties. However, its bitter taste and susceptibility to ruminal degradation limit its practical use in mammals. Enteric coating technology might overcome these limitations by enabling targeted intestinal release. This study investigated effects of dietary supplementation with baicalin and coated baicalin on rumen fermentation, gastrointestinal microbiota, immune function and growth performance in Hu sheep. Thirty-six lambs with similar body weight (33.01 ± 2.68 kg) were randomly assigned to three groups (4 replicates per group, 3 sheep per replicate). The control group was fed basal diet (CON) while treatment I (BAI) and treatment II (C-BAI) groups were fed a basal diet supplemented with 0.1% baicalin and coated baicalin, respectively. After a 60-d feeding trial, baicalin and coated baicalin supplementation improved total weight gain and average daily gain compared with CON group (P < 0.05). In addition, BAI and C-BAI groups exhibited higher total antioxidant capacity (P < 0.05) and catalase activity (P < 0.05) with associated lower malondialdehyde levels (P < 0.05). Immunoglobulin G and anti-inflammatory cytokines interleukin-4 (IL-4) were also increased (P < 0.001). Notably, IgM, IL-10 and IL-4 in the C-BAI group exceeded those of the BAI group (P < 0.001). Microbiome analysis revealed that baicalin supplementation enriched abundance of beneficial bacterial taxa including Firmicutes and Lachnoclostridium (P < 0.05) and reduced potential pathogen abundance, e.g., Treponema and Ralstonia (P < 0.05). The C-BAI group also showed increased abundance of the beneficial Bradyrhizobium compared with CON (P < 0.05). Metabolomic analysis revealed that baicalin altered propionate and tyrosine metabolic pathways (P < 0.05), while coated baicalin modulated penicillin metabolism and glyceride metabolism in jejunum (P < 0.05) increasing ATP production. Overall, these results indicated enhanced nutrient metabolism and gut health in the presence of dietary baicalin. Dietary supplementation with baicalin and coated baicalin improved growth performance, antioxidant status, immunity and beneficially modulated the microbiome-metabolome crosstalk in Hu sheep. Notably, uncoated baicalin exerted more pronounced effects on growth performance and supported a role for baicalin as a potential and functional feed additive.","42221754":"ID: 42221754\nTitle: Functional fermented dairy products: a review of mechanisms, health potential, and technological challenges.\nAbstract: Fermented dairy products such as yoghurt, kefir and cheese are increasingly recognised as functional foods due to the metabolic activity of lactic acid bacteria and the associated microbial communities, including probiotics. During dairy fermentation, these microorganisms generate bioactive compounds, such as bioactive peptides, exopolysaccharides, organic acids and other metabolites, which may contribute to host health. There is emerging evidence that fermented dairy products can influence gastrointestinal function, immune regulation, metabolic health and cardiovascular risk, via mechanisms involving modulation of the gut microbiota, stabilisation of the epithelial barrier and inflammatory signalling pathways. In addition, fermentation may improve lactose digestion, enhance nutrient bioavailability, and generate peptides with anti-hypertensive or antioxidant properties. However, translating these results into consistent health benefits is challenging due to the significant variability in microbial strains, product composition, processing conditions and dosage. Safety considerations such as biogenic amines, sodium content, allergenicity and antimicrobial resistance also require careful monitoring. Future progress in this field will depend on improved product characterisation, strain-level identification and well-designed human intervention studies that integrate multi-omics approaches. In conclusion, fermented dairy products show great potential as a source of bioactive compounds, but more robust clinical evidence and standardised methodologies are required to firmly establish their role in promoting human health.","42235390":"ID: 42235390\nTitle: Selenium and Vitamin E restore redox balance, gut microbiota and reproductive function against cadmium-induced toxicity in male rabbits.\nAbstract: This study evaluated the protective effect of selenium (Se) and vitamin E (VE) against cadmium (Cd) induced testicular and microbiota alterations in male rabbits. Sixty male rabbits were assigned to four groups: control, cadmium group (T1) and two co-treatment groups receiving cadmium plus selenium and vitamin E (T2 and T3). The results revealed that selenium and vitamin E substantially (P < 0.05) restored organ and body weight along with hematological parameters against cadmium intoxication in contrast to control group. Selenium and vitamin E mitigated (P < 0.05) cadmium-induced toxicity by elevating testosterone level and antioxidants (SOD, CAT, POD and TAC), suppressing ROS production and lowering MDA as compared to control group. Further, selenium and vitamin E significantly (P < 0.05) reduced lipid peroxidation, restored fatty acid composition, improved sperm quality, preserved cellular integrity and protected testicular function by counteracting cadmium-induced toxicity compare to control group. Moreover, cadmium altered gut microbial composition significantly (P < 0.05) by reducing beneficial taxa (Firmicutes, Bacteroides and Lactobacillus) and increasing pro-inflammatory pathogens (Proteobacteria). Selenium and vitamin E fully restored microbial metabolic pathways critical for gut health compared to control group. Overall, the results underscore the synergetic potential of selenium and vitamin E for antioxidant-microbiota modulation to counter cadmium induced reproductive toxicity, offering valuable insights for toxicology interventions and reproductive health.","42240953":"ID: 42240953\nTitle: Phenotypic, Genomic, and In Vivo Characterization of a Host-Derived Limosilactobacillus fermentum RLF77 with Potential to Prevent Post-weaning Diarrhea in Rabbits.\nAbstract: Following the 2020 ban on antibiotic growth promoters in animal feed, diarrheal disease in weaned rabbits has become an increasingly important challenge for the rabbit industry. Due to their superior intestinal adaptability and colonization potential, host-derived probiotics are considered promising alternatives. In this study, Limosilactobacillus fermentum RLF77, a lactic acid bacterium, was isolated from the intestinal contents of healthy young rabbits. Strain RLF77 showed a favorable safety profile, including γ hemolysis, a negative indole reaction, and no production of biogenic amines. Furthermore, the strain exhibited strong tolerance to heat, acidic conditions, bile salts, and simulated gastrointestinal fluids, as well as broad antimicrobial activity against a range of enteric pathogens. It also displayed moderate cell surface hydrophobicity, auto-aggregation ability, and strong antioxidant activity. Whole genome sequencing revealed that RLF77 possesses a 2.31 Mbp genome enriched in genes involved in carbohydrate and amino acid metabolism, stress response, and oxidative defense. In addition, genome mining identified biosynthetic gene clusters putatively encoding enterolysin A. Oral administration in mice further supported the in vivo safety of RLF77 and significantly increased villus height and the villus height/crypt depth ratio. In an E. coli-challenged weaned rabbit model, dietary RLF77 supplementation improved growth performance, reduced diarrhea incidence, enhanced immune and antioxidant capacity, alleviated intestinal injury, and improved gut microbiota composition by increasing microbial richness and Akkermansiaceae abundance. Collectively, the host-derived strain L. fermentum RLF77 is a safe and promising probiotic candidate for improving intestinal health and preventing post-weaning diarrhea in rabbits.","42241759":"ID: 42241759\nTitle: Cecal metagenome and mucosal transcriptome of broilers after an enteric challenge and fed diets with different fiber types and concentrations1.\nAbstract: This study evaluated the effects of dietary fiber supplementation on broiler gut health during a subclinical enteric challenge. Birds were assigned to either an unchallenged control or a challenged control, followed by six dietary treatments applied to challenged birds. These treatments included 3% oat hulls (OH), 3% soy hulls (SH), and four combinations of 1.5% OH or SH with 1.5% wheat middlings (WM) or sugar beet pulp (SBP). A randomized complete block design was used with 2,160 day-old YP × Ross 708 male broiler chicks allocated to eight treatments, each with nine replicate floor pens and 30 birds per pen. Birds were inoculated with Eimeria followed by Clostridium perfringens, and cecal samples were collected at 21 days of age for shotgun metagenomic and transcriptomic analyses. The enteric challenge significantly reduced microbial diversity, depleted butyrate-producing bacteria, and enriched pathways associated with bacterial growth and virulence while triggering inflammatory signaling and suppressing proliferative pathways in the host. Supplementation with dietary fiber modulated these responses through distinct yet complementary mechanisms. The group receiving OH with WM enriched butyrate-producing bacteria, including Faecalibacterium prausnitzii, reduced C. perfringens abundance, and downregulated inflammatory pathways. Birds fed OH with SBP showed increased populations of lactic acid producing bacteria and Bifidobacterium animalis while suppressing TNFα, NF-κB and IFNγ signaling. Diets containing SH combinations enhanced metabolic pathways related to pyruvate fermentation and stachyose degradation, primarily driven by Lactobacillus species. Despite having distinct microbial compositions, all fiber treatments restored epithelial proliferation pathways in the host transcriptome, indicating convergent potentially beneficial effects on intestinal health. Integration of bacteriome and transcriptome data revealed coordinated relationships between specific bacterial species, including Stutzerimonas stutzeri, Bacteroides caecae, and Eubacteriaceae bacterium ES3, and host genes involved in immune function and energy metabolism. These findings provide a mechanistic framework for developing targeted nutritional strategies using specific fiber combinations to enhance gut resilience in antibiotic-free broiler production systems.","42254439":"ID: 42254439\nTitle: Nutraceutical Interventions in Stunting: Advances, Challenges, and Prospects.\nAbstract: Childhood stunting remains a major global health challenge, reflecting the cumulative effects of inadequate nutrition, recurrent infection, and chronic intestinal dysfunction during early life. Beyond conventional micronutrient supplementation, nutraceutical interventions have emerged as complementary strategies to address the complex biological pathways underlying impaired linear growth. This review synthesizes current evidence on nutraceutical approaches to stunting, including improvements in macronutrient quality, bioactive food components, and microbiome-targeted strategies such as probiotics, prebiotics, synbiotics, postbiotics, and microbiota-directed foods. Evidence from clinical and preclinical studies indicates that nutraceutical effects on growth are generally modest and heterogeneous, with more consistent effects on weight gain than on height-for-age (HAZ). Variability in efficacy is strongly influenced by baseline nutritional status, environmental enteric dysfunction (EED), infection burden, dietary quality, and water, sanitation, and hygiene (WASH) conditions. Mechanistically, nutraceuticals may act through modulation of gut barrier integrity, inflammatory tone, microbial metabolism, and endocrine signaling pathways, particularly those involving the growth hormone-insulin-like growth factor-1 (GH-IGF-1) axis. Recent microbiota-directed food trials provide proof-of-concept that targeted correction of microbiome immaturity and gut dysfunction can support linear growth. Looking forward, advances in nutrigenomics, microbiome science, and epigenetics support a shift toward precision nutrition strategies that tailor interventions to biological responsiveness and context. Systems biology approaches integrating multi-omics data, network pharmacology, and interpretable artificial intelligence are expected to refine mechanistic understanding and guide intervention design. Effective translation will require rigorous trial designs, regulatory clarity, and integration of nutraceuticals within broader stunting reduction frameworks in low- and middle-income countries.","42258757":"ID: 42258757\nTitle: Nonocclusive Mesenteric Ischemia in Cardiogenic Shock: Mechanisms of Splanchnic Hypoperfusion and Strategies for Early Detection.\nAbstract: Nonocclusive mesenteric ischemia (NOMI) is an underappreciated and lethal sequelae of cardiogenic shock (CS), forming the bulk of acute mesenteric ischemia in critically ill patients. In the setting of CS, reduced cardiac output, exposure to high doses of vasopressors, and nonpulsatile mechanical circulatory support (MCS) result in a \"perfect storm\" of hemodynamic insults to the splanchnic circulation. Mortality from NOMI in this population exceeds 70-90%, largely attributable to late diagnosis after irreversible transmural necrosis has already occurred. In this review, we describe the pathophysiology of NOMI in the setting of CS, considering the effects of sympathoadrenergic and renin-angiotensin mediated vasoconstriction, the loss of mesenteric pulsatility due to contemporary MCS, and the gut-heart axis as an enhancer of systemic injury. We address topics such as the under detection of limb ischemia with current imaging modalities, the potential of new markers of gut dysfunction, such as intestinal fatty acid-binding protein and citrulline, and bedside imaging, including contrast-enhanced ultrasound and assessment of portal vein pulsatility. We review strategies for prevention and management, including early MCS escalation, minimizing vasopressor requirements, and careful enteral feeding. Finally, we recognize the need for prospective multicenter registries and AI-based risk stratification to facilitate the diagnosis of this under-recognized condition. Understanding that the gut is not a \"mere\" bystander in the pathophysiology of CS, but rather a central participant, it may be the gateway to reducing the ongoing high mortality of this syndrome.","42267298":"ID: 42267298\nTitle: Maternal obesity and inadequate gestational weight gain disrupts placental dopaminergic signaling: impact on infant neurodevelopment.\nAbstract: The maternal-fetal axis plays a critical role in human development. Obesity during pregnancy may be associated with alterations in this axis, particularly the placental dopaminergic signaling, potentially affecting infant neurodevelopment. Participants (n=35) from the OBESO cohort (Mexico City) were classified by pregestational BMI as normal weight (n=20) or obese (n=15). Clinical and anthropometric variables of the mother-infant dyads were recorded. Neurodevelopment was evaluated in one-month-old infants using the Bayley-III Scales and classified as normal or altered (score ≤7 in any domain). Placental dopamine (DA) concentrations were quantified by ELISA and correlated with neurodevelopmental status. A subset of samples was analyzed by Western blot to explore the expression of key dopaminergic components: tyrosine hydroxylase (TH), catechol-O-methyltransferase (COMT), vesicular monoamine transporter 2 (VMAT2), organic cation transporter 3 (OCT3), dopamine transporter (DAT), and dopamine receptor D2 (DRD2). Reduced placental DA concentrations, together with altered expression of key dopaminergic elements characterized by increased COMT and DAT, and decreased VMAT2, were observed in association with maternal obesity, inadequate gestational weight gain, and altered infant neurodevelopment. This study provides exploratory evidence that maternal obesity and inadequate GWG may be associated with early alterations in the intrauterine metabolic and neuroendocrine environment, including changes in the placental dopaminergic system. Differences in the expression of COMT, DAT, and VMAT2, together with lower placental DA concentrations, which may be linked to early neurodevelopmental variability in infants. Overall, the results suggest a potential relationship between maternal metabolic status and placental neuroendocrine pathways, warranting further investigation in larger and longitudinal studies.","42283770":"ID: 42283770\nTitle: Divergent Colorectal Cancer Risks Following Metabolic Bariatric Surgery: Anatomical Remodeling and the Genotoxic Microenvironment.\nAbstract: Metabolic bariatric surgery (MBS) reduces overall cancer incidence, yet colorectal cancer (CRC) risk diverges by procedure. Roux-en-Y gastric bypass (RYGB) has been associated with increased long-term CRC risk (HR 1.55 at 10-14 years), whereas sleeve gastrectomy (SG) shows no equivalent elevation, though shorter follow-up (mean 4.5 vs. 8.5 years) precludes definitive conclusions. This review develops a biologically plausible mechanistic framework for these divergent outcomes. RYGB-induced anatomical bypass and accelerated transit are proposed to drive distal substrate overload, with an associated shift of the colonic microbiome toward proteolytic fermentation. The proposed genotoxic luminal environment is characterized by convergent actions of secondary bile acids, tyramine, and hydrogen sulfide, compounded by butyrate depletion. By preserving gastrointestinal continuity, SG is hypothesized to avoid these alterations. These considerations support integrating baseline CRC risk into surgical selection and procedure-specific surveillance after RYGB.","42287941":"ID: 42287941\nTitle: Dynamic dual roles of gut microbial metabolites in Alzheimer's disease: Translational insights for gut-brain axis interventions.\nAbstract: Alzheimer's disease (AD) is a complex neurodegenerative disorder in which the microbiome-gut-brain axis (MGBA) plays a crucial regulatory role through microbial metabolites. This review analyzes the concentration trajectories of representative metabolites across different disease stages and compartments, and synthesizes current preclinical evidence on how these metabolites influence AD pathogenesis, with particular attention to the mechanisms underlying their dual roles. We integrate evidence for bidirectional pathological crosstalk: gut dysbiosis accelerates central neurodegeneration through altered metabolite signaling, while AD-related neuropathology concurrently disrupts gut homeostasis. The review also evaluates MGBA-targeted intervention strategies and critically identifies key limitations that hinder clinical translation, including unclear dose-response relationships and insufficient patient stratification. We note that brain-to-gut mechanistic evidence remains considerably less developed than that for the gut-to-brain direction, and that signaling crosstalk among multiple metabolites is poorly characterized. Future studies should prioritize the neuroendocrine and immune pathways linking central pathology to gut dysbiosis, the dose-response relationships of individual metabolites, and standardized multi-metabolite profiling within prospective longitudinal cohorts. Addressing these gaps will advance mechanism-guided, precision-targeted interventions that mitigate the prevalent gut dysfunction in AD and confer global therapeutic benefits.","42294883":"ID: 42294883\nTitle: Astragalus polysaccharides ameliorate perinatal metabolic syndrome in sows via enhancing butyrate-producing bacteria.\nAbstract: Astragalus polysaccharide (APS), a bioactive phytomacromolecule from Astragalus membranaceus, exhibits anti-inflammatory, antioxidant, and immunomodulatory activities. Given mammals' lack of endogenous glycosidases for APS catabolism, this study hypothesizes its bioactivity stems from gut microbial interactions, investigating APS-mediated microbiome remodeling and therapeutic effects on perinatal metabolic syndrome (PeriMS) in sows. In vitro fermentation showed that APS significantly increased short-chain fatty acid (SCFA) production, with acetate (44.51 mmol/L), propionate (17.37 mmol/L), and butyrate (22.04 mmol/L) levels notably elevated and enriched canonical butyrate-producing taxa (g_norank_f_Muribaculaceae, g_Monoglobus, g_unclassified_f_Lachnospiraceae, P < 0.05). In vivo, gestational APS supplementation (from day 90) improved piglet weaning weight, reduced maternal backfat loss during lactation, shortened post-weaning estrus interval, elevated intestinal butyrate, alleviated systemic inflammation/oxidative stress, and mitigated PeriMS. Mechanistic analysis associated PeriMS improvement with butyrate-producing bacteria, with butyrate playing a key role in gut health enhancement. These findings establish APS as a prebiotic, highlighting the gut microbiota-SCFA axis as a therapeutic target for PeriMS. This study provides targeted mechanistic evidence that the gut microbiota-SCFA axis mediates PeriMS improvement by APS. Mechanistic analysis linked PeriMS improvement to butyrate-producing bacteria, with butyrate playing a key role in gut health enhancement, which was verified by a sodium butyrate rescue experiment. These findings establish APS as a prebiotic, highlighting the gut microbiota-SCFA axis as a therapeutic target for PeriMS. This work provides novel evidence for microbiota-SCFA axis involvement in sow perinatal metabolic health, offering translational strategies to improve livestock metabolic health through APS supplementation. In intensive pig farming, 40% of multiparous sows develop perinatal metabolic syndrome (PeriMS) around farrowing, causing $150-$200 annual loss per sow due to inflammation (e.g., higher IL-6), oxidative stress, and extended weaning-to-estrus intervals (2.1 days). Gut dysfunction-marked by fewer butyrate-producing bacteria and increased endotoxin-triggers barrier damage and inflammation. Supplementing with Astragalus polysaccharides (APS, 10 g/day) enhances beneficial bacteria like Muribaculaceae and butyrogenic Bacteroides, raising butyrate in vitro. In sows, APS lowers endotoxemia and gut inflammation (calprotectin), correlating with reduced postpartum IL-6 and reactive oxygen species. It also improves productivity: less backfat loss and heavier weaned piglets. By targeting gut-barrier crosstalk, APS breaks the inflammation-metabolism cycle, providing a sustainable alternative to antibiotics to enhance peripartum sow health and profitability.","42314521":"ID: 42314521\nTitle: Maternal egg yolk supplementation alters offspring liver choline status and is associated with functional network activation and monoamine metabolism in a sow-piglet model.\nAbstract: Maternal nutrition plays a major role in neurodevelopment. This study hypothesized that maternal egg yolk supplementation will influence offspring choline concentrations, and these changes will be associated with resting-state network (RSN) activation and monoamine neurochemistry at weaning. Sows were fed a control (CON; n = 6) or an egg yolk-supplemented diet (EGG; n = 5) from gestation day 70 to weaning at postnatal day 21, and piglet liver and plasma were collected (CON, n = 24; EGG, n = 20) for choline and metabolite quantification at weaning. Maternal egg yolk supplementation increased liver choline and methionine concentrations in piglets (p < .05). Given our previous findings that egg yolk supplementation elevated executive control and cerebellar functional activation, the associations between metabolites and RSNs were examined. Liver choline was correlated with executive (r = 0.4584) and auditory network activation (r = -0.4751), while plasma choline was correlated with visual network activation (r = 0.5295) (p < .05). As we previously reported that maternal egg yolk supplementation altered piglet monoamine homeostasis, its links to choline and metabolite concentrations were assessed. Liver choline was associated with anterior hippocampal norepinephrine (r = 0.3275) and cerebellar serotonin metabolism (r = 0.3043) and liver TMAO was associated with anterior hippocampal norepinephrine (r = 0.3896), while plasma choline was linked to caudate serotonin (r = 0.3902) and dopamine (r = -0.3763) metabolism (p < .05). Overall, maternal egg yolk supplementation altered offspring choline and metabolite status, which was associated with RSNs and monoamines. These findings broaden our understanding of how one-carbon metabolite status may relate to neurochemical and functional brain outcomes in offspring.","42327764":"ID: 42327764\nTitle: Trained immunity as a systemic bridge: the liver-gut-immune-oral axis in the comorbidity of chronic liver disease and periodontitis.\nAbstract: Trained immunity (TI) reveals that innate immune cells acquire long-term functional memory through metabolic and epigenetic reprogramming. This review examines TI in chronic liver diseases and periodontitis, proposing the \"Liver-Gut-Immune-Oral Axis\" as a framework where TI bridges these comorbidities. The forward pathway, currently inferred from mechanistic and associative studies, proposes that liver-gut dysfunction induces bone marrow training, generating hyper-reactive monocytes that amplify periodontal inflammation. The reverse pathway, similarly conceptual, proposes that periodontal pathogens reprogram hematopoietic progenitors, accelerating liver disease progression. Both converge on shared metabolic-epigenetic reprogramming circuits. We emphasize that this axis represents a conceptual framework synthesized from current mechanistic and associative evidence; its validity as an integrated, causally-linked biological system awaits direct experimental validation. Targeting TI with metabolic modulators, epigenetic drugs, or periodontal interventions offers strategies to disrupt this cycle and advance precision medicine for inflammatory comorbidities.","42332440":"ID: 42332440\nTitle: Dietary intake and hyperuricemia among US adults: A matched case-control analysis of NHANES 2001-2020.\nAbstract: Hyperuricemia, a chronic metabolic condition characterized by elevated serum uric acid levels, is a major risk factor for gout and has also been associated with cardiovascular disease, hypertension, chronic kidney disease, and metabolic syndrome. Although diet is widely recognized as an important modifiable factor in hyperuricemia, the associations between specific food groups and hyperuricemia remain incompletely understood. In this frequency-matched case-control analysis using data from the National Health and Nutrition Examination Survey 2001-2020, we included 886 individuals with hyperuricemia and 2171 matched controls. Dietary intake was assessed using 24-hour dietary recall data. Unconditional multivariable logistic regression models were applied to examine the associations between food group intake and hyperuricemia, and odds ratios (ORs) with 95% confidence intervals (CIs) were calculated by comparing the highest with the lowest intake quantiles. False discovery rate-adjusted P for trend values were additionally calculated to account for multiple comparisons. Higher intake of legumes, nuts, and seeds (OR, 0.74; 95% CI, 0.57-0.96), grain products (OR, 0.78; 95% CI, 0.62-0.96), whole-wheat bread, oats, and brown rice (OR, 0.76; 95% CI, 0.62-0.93), eggs (OR, 0.85; 95% CI, 0.77-0.94), and milk products (OR, 0.64; 95% CI, 0.51-0.79) were associated with lower odds of hyperuricemia. In contrast, higher intake of meat, poultry, and fish (OR, 1.22; 95% CI, 1.12-1.33), fish and seafood (OR, 1.09; 95% CI, 1.01-1.23), sugars, sweets, and beverages (OR, 1.60; 95% CI, 1.28-2.00), soft drinks (OR, 1.11; 95% CI, 1.03-1.21), sugar-sweetened soft drinks (OR, 1.13; 95% CI, 1.03-1.23), and sugar-sweetened tea (OR, 1.86; 95% CI, 1.11-3.12) were associated with higher odds of hyperuricemia. The overall directions of the observed associations were largely unchanged after false discovery rate adjustment, although fewer trend tests remained statistically significant. Several dietary factors were associated with hyperuricemia in this National Health and Nutrition Examination Survey-based frequency-matched case-control analysis. These findings may help inform dietary strategies for the prevention and management of hyperuricemia. However, the observed associations should be interpreted cautiously, particularly in light of multiple-comparison adjustment, and further studies are warranted to confirm the findings and clarify their clinical implications.","42334068":"ID: 42334068\nTitle: Dietary glycemic index/glycemic load and knee osteoarthritis: associations with inflammation and oxidative stress.\nAbstract: Although dietary glycemic index (GI) and glycemic load (GL) are known to affect inflammation and oxidative balance, their roles in OA are unclear. This study aims to investigate the relationship between dietary GI and GL with inflammation, oxidative stress, and clinical symptoms in patients with knee osteoarthritis (KOA). In a cross-sectional study, 160 patients diagnosed with KOA were included. Dietary intake was assessed using a validated food frequency questionnaire, and daily GI and GL values were calculated. Clinical symptoms were assessed using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Higher dietary GI and GL were significantly associated with increased serum levels of malondialdehyde (MDA), total oxidant status (TOS), tumor necrosis factor-alpha (TNF-α), and high-sensitivity C-reactive protein (hs-CRP), as well as with decreased total antioxidant capacity (TAC). Dietary GI and GL were positively correlated with the total WOMAC score, as well as with the WOMAC physical activity and stiffness. High dietary GI and GL may be associated with oxidative stress and inflammatory responses, and may worsen clinical symptoms in KOA patients. Nutritional strategies emphasizing low-GI/GL diets may contribute to better symptom control and disease management in KOA.","42334457":"ID: 42334457\nTitle: Protein consumption during pregnancy and risk of gestational diabetes mellitus: Insights from a multi-center case-control study.\nAbstract: Gestational diabetes mellitus (GDM) poses major health risks for mothers and infants. Evidence on the association between dietary protein intake and GDM risk remains inconsistent. This study investigated dietary protein quantity and quality in relation to GDM. A hospital-based case-control study was conducted in Isfahan, Iran, involving 200 cases and 263 controls. Dietary intake was assessed using three 24-h dietary records, and protein intake was categorized into plant- and animal-based sources. Multivariate logistic regression models were applied to evaluate associations. Higher plant protein intake was associated with a significantly lower risk of GDM (OR = 0.34; 95% CI: 0.20-0.59). Similarly, higher seafood (OR = 0.40; 95% CI: 0.24-0.68) and egg intake (OR = 0.59; 95% CI: 0.35-0.98) were inversely associated with GDM risk. In contrast, total protein, animal protein, poultry, dairy protein, aromatic amino acids, and branched-chain amino acids showed no significant or meaningful trend with GDM risk. Our study did not identify significant associations between total or animal protein intake during pregnancy and GDM risk. However, higher consumption of plant protein, seafood, and eggs was associated with lower odds of GDM in multivariable-adjusted models that accounted for BMI, total energy intake, socioeconomic status, and other relevant confounders. Given the observational case-control design, these findings cannot establish causality, and the possibility of residual confounding remains. Nevertheless, the results suggest that protein-intake quality may play a role in GDM risk, warranting confirmation in prospective cohorts and randomized trials.","42334792":"ID: 42334792\nTitle: Dietary Interventions Targeting Maternal Obesity: Intergenerational Effects, Mechanisms, and Translational Insights.\nAbstract: Maternal obesity is a major public health challenge that elevates pregnancy risks and predisposes offspring to lifelong metabolic disorders. Nutrition, as a modifiable determinant of the intrauterine environment, offers opportunities to interrupt this intergenerational cycle. This review synthesizes evidence on polyphenols, vitamins, omega-3 fatty acids, dietary fiber, probiotics, prebiotics, whole grains, and iron, highlighting underlying mechanisms and translational implications for maternal and offspring health. Preclinical studies demonstrate that these interventions improve maternal metabolism, modulate placental function, regulate gut microbiota, alter breast milk composition, and influence epigenetic programming. Clinical evidence is relatively strong for folic acid and vitamin D, whereas evidence for dietary fiber is emerging, with long-term offspring outcomes still insufficiently investigated. Polyphenols and omega-3 fatty acids exert antioxidant and anti-inflammatory effects, but translation is constrained by low bioavailability and limited safety data. Probiotics and prebiotics show potential in modulating maternal-infant gut health, yet trial outcomes are inconsistent and strain-specific. Whole grains and fortified foods may represent feasible options for population-level implementation, although robust longitudinal studies in obese pregnancies are still lacking. Dietary interventions hold promise for mitigating maternal obesity by improving metabolism, reducing inflammation, supporting placental function, and modulating gut microbiota, breast milk composition, and epigenetic programming. However, evidence is largely preclinical and long-term human data are limited. Future research should prioritize well-designed clinical trials and personalized approaches tailored to maternal phenotype and nutritional status to enable effective, scalable strategies for breaking the intergenerational cycle of obesity.","42335402":"ID: 42335402\nTitle: Ultra-Radiostable Covalent Conformationally Interlocked Networks Enabling a Universal Radiometal-Labeling Platform for Cancer Radioembolization.\nAbstract: Transcatheter arterial embolization (TARE) has emerged as a highly effective locoregional treatment for advanced liver cancer, which represents a significant advancement in clinical practice. Nonetheless, the utilization of traditional radioactive microspheres in TARE is hindered by various material and technical challenges that necessitate resolution. Herein, we present, for the first time, well-designed and synthesized conjugated poly(imide dioxime) ligand-based microspheres (PID-Ms) with a remarkable radiometal coordinate covalent conformational interlocked network. PID-Ms can be radiolabeled with various radionuclides, including 177Lu, 90Y, 188Re, 68Ga, and 99mTc, can be achieved at low temperatures (40°C), and for diagnostic imaging and radiotherapy applications. The combined strategy of extended x-ray absorption fine structure spectroscopy (EXAFS), DFT calculations, and in vitro and in vivo radiostability experiments collectively confirmed that radiometal-PID complexes exhibit ultra-high radiostability. 177Lu-PID-Ms were employed to accurately predict normal organ shunts and radiotherapy in rat and rabbit VX2 orthotopic live tumor models, demonstrating their ultra-radiostability and remarkable anti-tumor efficacy. Furthermore, Radiometals-PID-Ms have an adjustable shelf life, enabling on-demand radiolabeling for drug preparation, achieving rapid 'on-demand' capability. This innovative approach has the potential to inspire the synthesis of numerous coordination polymeric materials for various applications in PET/SPECT-mediated radiopharmaceutical therapy, alpha-nucleophile-targeted radiotherapy, and MRI contrast agents.","42335566":"ID: 42335566\nTitle: Therapeutic potential of phenolic acids in bone tissue healing and regeneration: a scoping review.\nAbstract: This scoping review evaluated the effects of dietary phenolic acids on bone healing and regeneration, focusing on their osteogenic and antiresorptive properties. The review followed the PRISMA-ScR guidelines. A comprehensive search was conducted in PubMed, Scopus, Web of Science, Embase, and Cochrane Library. Eligible studies included in vitro and in vivo investigations assessing the effects of phenolic acids on bone tissue. Two reviewers independently screened studies, extracted data, and synthesized the findings. Of 1053 records identified, 49 studies were included. Phenolic acids, naturally found in fruits, vegetables, coffee, tea, cereals, and other plant-derived foods, demonstrated osteoprotective effects in experimental models. Caffeic acid (CAPE), chlorogenic acid, and ferulic acid stimulated osteoblast proliferation and differentiation, enhanced mineralization and osteogenic gene expression, and inhibited osteoclastogenesis and inflammatory pathways. Other compounds, including cinnamic and gallic acids, also exhibited anabolic and antiresorptive effects. In animal models, CAPE and chlorogenic acid prevented bone loss, whereas ferulic acid promoted bone repair and regeneration. Overall, phenolic acids demonstrated multifunctional properties related to osteogenesis, modulation of bone metabolism, and inhibition of bone resorption, thereby contributing to bone regeneration and homeostasis. However, current evidence remains predominantly preclinical, and translation to humans may be influenced by factors such as dietary intake, bioavailability, metabolism, and long-term exposure. Therefore, well-designed clinical and nutritional studies are needed to validate their efficacy and translational applicability in human bone health.","42337761":"ID: 42337761\nTitle: Triple primary synchronous liver cancer in one patient: the first case report and origin speculation through bioinformatics.\nAbstract: A diagnosis of multiple primary liver tumors is extremely rare. Preoperative diagnosis based on imaging findings is difficult. Moreover, the clinical benefits of treatment strategies for multiple liver cancers remain unclear. Here, we report a case of three synchronous primary liver tumors with three distinct pathological types-hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (ICC), and combined hepatocellular-cholangiocarcinoma (cHCC‑CCA)-in a single patient. Bioinformatics analysis supported at least two clonal origins, with cHCC‑CCA and ICC sharing a common lineage based on identical HBV integration sites. A 63-year-old female with a history of hepatitis B for several years presented with three lesions in hepatic segment VIII. Multiphase magnetic resonance imaging with gadolinium ethoxybenzyl diethylenetriaminepentaacetic acid revealed a diagnosis of multiple lesions, namely, cHCC‑CCA, with multiple intrahepatic metastases. The AFP level was normal, while the CA 19 - 9 level was mildly elevated (normal range ≤ 30.00 U/ml). Hepatectomy was performed, and postoperative assessment confirmed that the large lesion was cHCC‑CCA. However, the small lesions close to the large lesion were HCC and ICC. Gene testing revealed distinct mutational profiles among the three tumors. Similar gene mutations were detected in cHCC‑CCA and ICC. We also found that gene fragments of hepatitis B virus-C (HBV-C) were inserted into the genomes of ICC and cHCC‑CCA rather than that of HCC. The genomic integration site of HBV-C in cHCC‑CCA and ICC was the same. We report an extremely rare case of three synchronous primary liver tumors with three distinct pathological types (HCC, ICC, and cHCC‑CCA) in a single patient. Bioinformatics analysis supported at least two clonal origins, with cHCC‑CCA and ICC sharing a common lineage based on identical HBV integration sites. Hepatectomy represents a potential radical strategy for the treatment of multiple PLCs.","42338249":"ID: 42338249\nTitle: Serum Iodine Concentration as a Biomarker for Individual Iodine Nutrition and Thyroid Function in Pregnant Women: A Cross-Sectional Study in Hubei Province.\nAbstract: The physiological demands of pregnancy substantially alter iodine metabolism and thyroid function. This critical period heightens the requirement for iodine, making deficiency a significant risk factor for both maternal and fetal thyroid dysfunction. This study aimed to evaluate the iodine nutritional status of pregnant women in Hubei Province, explore the relationship between serum iodine concentration (SIC) and thyroid function, and determine the prevalence of thyroid disorders. The eligible participants underwent a face-to-face interview and completed questionnaire surveys to collect baseline information and dietary intake data. Serum thyroid hormones, thyroid antibodies, SIC, and urine iodine concentration (UIC) were measured. The 95% reference intervals of SIC were established and ROC analysis was applied to compare the predictive ability of SIC and UIC for thyroid dysfunction. Hubei Province, China. 1197 eligible pregnant women were included in this study. This study revealed a thyroid dysfunction prevalence of 28.40%, with hypothyroxinemia being the most prevalent thyroid function abnormality, accounting for 79.7% of all thyroid dysfunction cases. Significant differences in hypothyroxinemia prevalence were noted across pregnancy trimesters (P < 0.001), with the highest prevalence in the first trimester and the lowest in the third. In the first trimester, SIC was negatively correlated with TSH (r = -0.195, P < 0.001) and positively correlated with FT3 (r = 0.294, P < 0.001). Additionally, SIC demonstrated a positive correlation with FT4 in each trimester (all P < 0.001). Finally, the SIC reference intervals for pregnant women in the first, second, and third trimesters were 50.08∼118.61 µg/L, 59.16∼127.44 µg/L, and 53.61∼118.67 µg/L, respectively. SIC can serve as a reliable indicator for evaluating individual iodine nutritional status and predicting thyroid dysfunction.","42339955":"ID: 42339955\nTitle: Biogenic Amines Control in Bacterial-Type Douchi Using Bacillus velezensis A1: Strain Screening, Process Optimization, and Industrial Validation.\nAbstract: The study focused on biogenic amines (BAs) in fermented products, particularly douchi. Three strains showing high protease activity (> 90.00 U/mL) and low BA levels (< 40 mg/kg) were isolated from naturally fermented douchi: A1 Bacillus velezensis, A2 B. glycinifermentans, and A3 B. subtilis. A1, with the lowest total biogenic amine (TBA) levels, was selected as the representative strain. The optimal fermentation conditions (8% inoculum, 37°C temperature, 3 days duration) reduced TBA to levels well below the FDA standard (< 1000 mg/kg). Compared to the natural fermentation (NF), it was verified that the TBA of douchi was lowered to 10.51 ± 0.21 mg/kg after optimized fermentation, approximately reduced 10.80-fold. Spermine levels decreased by 43.17-fold, followed by tyramine and phenethylamine. Further, apply them to large-scale cultivation (scaled up by 100-fold) in actual production during colony-enhanced fermentation (CEF). The physicochemical properties and BA levels were monitored to assess the correlation. The findings showed that the douchi of CEF had up to 0.94% amino acid nitrogen (≥ 0.25% EN) and 0.72% total acid (≤ 2.5% EN). The TBA level was only 38.27 ± 0.13 mg/kg, significantly lower than NF (94.94 ± 2.59 mg/kg). This study proposed BA-reducing methods through strain screening and process optimization, particularly achieving large-scale verification from the laboratory to the factory. This approach significantly reduced the TBA levels in bacteria-type douchi, offering a crucial reference for the industrial-scale safe production of fermented soybean products. PRACTICAL APPLICATIONS: This research offers industrial-level guidance for douchi production. By utilizing Bacillus velezensis A1 and optimizing the process, the TBA can be reduced by a factor of 2.5 while maintaining product quality (T/GZSX 014-2018). This approach provides a collection of directly applicable safety production technology models for fermented soybean product enterprises, thereby assisting the industry in improving product safety and addressing health consumption demands.","42341503":"ID: 42341503\nTitle: Global and mitochondrial choline dehydrogenase contribute to goose fatty liver formation by differentially regulating energy metabolism, autophagy and oxidative stress related pathways.\nAbstract: The liver of geese has a strong ability to deposit fat and also has the ability to resist inflammation. Goose fatty liver represents a unique physiological model that exhibits no or low-level inflammation despite severe steatosis. Mitochondria and their proteins play a crucial role in the regulation of hepatic inflammation. However, it remains unclear whether choline dehydrogenase (CHDH), a mitochondrial protein, is involved in fat deposition and inflammation resistance in goose fatty liver formation. Here, we observed distinct expression patterns of mitochondrial CHDH (mCHDH) other than global CHDH (gCHDH) in goose versus mouse fatty livers, highlighting the unique role of mCHDH in goose fatty liver formation. Overexpression of gCHDH in goose primary hepatocytes led to increased cellular lipid accumulation, mitochondrial membrane potential (MMP) and respiratory chain complex II activity, alongside activation of immune response, apoptosis, cell adhesion, and lipid metabolism-related pathways. Moreover, overexpression studies in HepG2 cells revealed that both gCHDH and a mitochondrial targeting sequence-mutant CHDH (Δ1-38CHDH) elevated MMP, but they differentially regulated reactive oxygen species (ROS) level (Δ1-38CHDH slightly reduced intracellular ROS level) and the abundance of mitochondria-related proteins (gCHDH selectively increased tAMPK and decreased LC3B in mitochondrial lysates, whereas Δ1-38CHDH mainly reduced tAMPK and pAMPK in whole-cell lysates). Furthermore, transcriptome sequencing and mass spectrometry analyses revealed that CHDH may participate in processes such as immune response, ubiquitin-mediated degradation, autophagy, signal transduction and lipid metabolism. In summary, gCHDH and mCHDH contribute to the formation of goose fatty liver by affecting mitochondrial protein composition (AMPK, LC3B), mitochondrial function and related biological processes, though their effects exhibit certain differences. These findings provide new insights into the mechanism underlying the uniqueness of goose fatty liver.","42343527":"ID: 42343527\nTitle: [TCM pathogenesis and acupuncture-moxibustion differentiation and treatment of Crohn's disease based on the \"liver-spleen-intestine\" axis].\nAbstract: To explore the TCM pathogenesis and acupuncture-moxibustion differentiation and treatment of Crohn's disease (CD) based on the \"liver-spleen-intestine\" axis. It is considered that liver depression with qi disorder, which triggers the imbalance between the spleen and intestine, is the initiating factor of CD. The key pivotal point lies in the failure of the spleen in transportation due to spleen deficiency, which generates dampness, restricts the liver, and stagnates the intestine.Intestinal disorders affecting the internal organs, and harming the qi of the liver and spleen, are the final stage. The treatment takes \"relieving liver stagnation-strengthening spleen function-regulating intestine\" as the principle, using acupuncture and moxibustion as the method, and achieves holistic treatment through core main acupoints-selection of acupoints based on syndrome differentiation-symptomatic selection of acupoints. The primary acupoints include Taichong (LR3), Qimen (LR14),Yinlingquan (SP9), Zusanli (ST36), Tianshu (ST25), and Shangjuxu (ST37), and modifications are made according to symptoms, which can smooth liver qi dispersion, strengthen spleen-stomach function, and harmonize bowel activity. The above treatment methods can improve the symptoms of CD patients and provide new ideas for the clinical prevention and treatment of CD in TCM. 基于“肝-脾-肠”轴探讨克罗恩病（CD）的中医病机规律及针灸辨治方案。肝郁气乱，引动脾肠失衡为CD之始动环节；脾虚失运，酿湿遏肝滞肠为CD关键枢纽；肠病及脏，反伤肝脾之气为CD终末环节。针灸治疗以“疏肝-健脾-调肠”为纲，以针刺、艾灸为法，通过核心主穴-辨证选穴-对症选穴实现整体论治。核心取穴以太冲、期门、阴陵泉、足三里、天枢、上巨虚为主，随证配穴，使肝气疏泄、脾胃健达、肠腑和顺，以期改善CD患者症状，为中医临床防治CD提供新思路。.","42344601":"ID: 42344601\nTitle: A Critical Perspective on the Role of Thirdhand Smoke in Tumorigenesis: Initiator or Promoter.\nAbstract: Thirdhand smoke (THS), lingering tobacco residues on surfaces and in dust after smoking, has emerged as a growing public health concern. While the carcinogenic risks of first- and secondhand smoke are well established, the tumorigenic potential of THS remains inadequately understood. In this perspective, we systematically review the known THS-related compounds together with the existing biological findings to provide evidence on the carcinogenic potential of THS. We assess the role of THS in the context of the classic multistage model of tumorigenesis to address whether THS acts primarily as a tumor initiator, or as a promoter, or both. We also discuss methodological challenges in isolating the effects of THS on human health and the importance of animal models and outline emerging strategies for risk assessment, biomarker discovery, and precision prevention. This Perspective is the first to integrate chemical, toxicological, and mechanistic evidence to evaluate the carcinogenic potential of THS within the framework of the multistage model of tumorigenesis, offering a new conceptual foundation for understanding the role of THS in human cancer etiology, which is crucial for informing public health policies aimed at mitigating its impact.","42344916":"ID: 42344916\nTitle: Antibody-based regimens targeting PD-1/PD-L1 and VEGF/VEGFR in advanced or metastatic NSCLC: a meta-analysis of RCTs.\nAbstract: Antibody-based regimens targeting programmed cell death protein-1 (PD-1)/programmed death-ligand 1 (PD-L1) and vascular endothelial growth factor (VEGF)/vascular endothelial growth factor receptor (VEGFR) include conventional PD-1/PD-L1 inhibitors combined with anti-angiogenic monoclonal antibodies and PD-1/VEGF or PD-L1/VEGF bispecific antibodies, with or without chemotherapy. However, the clinical efficacy of these regimens in advanced or metastatic non-small cell lung cancer (NSCLC) remains unclear. This meta-analysis systematically evaluated their efficacy. PubMed, EMBASE, Web of Science, ClinicalTrials.gov, and the Cochrane Library were searched to identify relevant randomized controlled trials (RCTs) published up to February 2026. The main outcomes analyzed were progression-free survival (PFS) and overall survival (OS), with the hazard ratio (HR) and 95% confidence interval (95%CI) used for statistical analysis. The study protocol was registered on PROSPERO (CRD420251126421). Eleven RCTs were included in the analysis, with 4,426 participants. Antibody-based regimens targeting PD-1/PD-L1 and VEGF/VEGFR, with or without chemotherapy, were associated with better PFS (HR = 0.65, 95%CI: 0.57-0.75, p<0.001) and OS (HR = 0.79, 95%CI: 0.71-0.87, p<0.001) compared with the control regimen. For PFS, favorable subgroup estimates were observed in men (HR = 0.61), squamous histology (HR = 0.57), patients with liver metastases (HR = 0.49), those with higher PD-L1 expression (tumor proportion score (TPS)≥50%: HR = 0.65), those with epidermal growth factor receptor (EGFR) mutation (HR = 0.60). For OS, favorable subgroup estimates were observed in patients with Eastern Cooperative Oncology Group (ECOG) performance status (PS)=1 (HR = 0.80), men (HR = 0.80), smokers (HR = 0.82), those with liver metastases (HR = 0.57), those with PD-L1 TPS 1%-49% (HR = 0.67), and EGFR-mutant patients (HR = 0.80).

As energy is provided mainly by mitochondria housed in cochlear cells, mitochondrial dysfunction can possibly lead to sensorineural hearing loss (SNHL). Consequently, hearing benefits can potentially be derived if measures that can potentially enhance mitochondrial health are implemented. Unhealthy lifestyle practices have led to an increased risk of developing systemic oxidative stress and chronic inflammation. These, in turn, may result in persistent mitochondrial dysfunction in the body. Together, they could possibly lead to the development of SNHL and other non-communicable chronic diseases (NCDs). Factors such as micro-nutrient deficiencies, obstructive sleep apnea, and gut dysfunction could result in mitochondrial dysfunction. On the other hand, mitochondrial function could be enhanced by interventions such as better food choices and hormetic strategies like intermittent fasting. Conventional treatments of SNHL focus on steroid therapy in acute loss and hearing rehabilitation with hearing devices in chronic loss. By integrating personalized healthy lifestyle strategies, it is postulated that the chances of hearing recovery in acute SNHL could be enhanced in some patients. In chronic SNHL, they could help to prevent/slow down its progression and possibly also the progression of concomitant NCDs. Further research is warranted to substantiate these postulations.","42349142":"ID: 42349142\nTitle: Unraveling the metabolic basis of irradiation-induced flavonoid and flavor remodeling in Citri Grandis Exocarpium.\nAbstract: Irradiation, as a non-thermal processing technology, can effectively improve the quality of dried foods.

The color parameters of Citri Grandis Exocarpium had no significant changes after different doses of irradiation. 11 key flavonoid metabolites in Citri Grandis Exocarpium were obtained by flavonoid-targeted metabolomics, and 9 key flavor-active volatile compounds were analyzed by HS-GC-IMS with the analysis of the relative odor activity values. Moreover, the metabolic pathways of irradiation-induced flavonoid and flavor remodeling in Citri Grandis Exocarpium were finally elaborated, and the irradiation treatments were associated with the pathways of flavonoid biosynthesis, flavone and flavonol biosynthesis, phenylpropanoid biosynthesis, and fatty acid metabolism. The findings could provide a theoretical and research foundation for the application and development of irradiation technology in dried foods, as well as for the enhancement of flavonoids and flavor compounds.","42349146":"ID: 42349146\nTitle: Oxidized proteins in ready-to-eat beef are likely responsible for oxidative stress, dysbiosis and poor gut health in Wistar rats: underlying biochemical insights.\nAbstract: The global rise in convenience food consumption raises health concerns. This study examined the effects of ready-to-eat beef (RTE-B) versus freshly cooked beef (B) on protein digestibility, oxidative stress, gut microbiota, and colonic metabolome in Wistar rats (n = 14) over 10 weeks. RTE-B increased oxidative stress markers, including colon advanced protein oxidation products (1582 vs. 369 nmol/mg; p < 0.001). Gut microbiota composition shifted significantly, with a marked expansion of Akkermansia (18.5% vs. 0.5%; p < 0.01) and downward trends in several beneficial commensals. Metabolomics revealed elevated protein and lipid oxidation byproducts (e.g., 4-oxo-proline, DL-2,6-diaminopimelic acid) and reduced functional metabolites (e.g., spermidine, fumarate, and TMAO). These findings indicate that RTE-B promotes oxidative stress, impairs protein utilization, disrupts microbial balance, and alters colonic metabolic pathways, highlighting potential risks of oxidized proteins in processed meats for metabolic and intestinal health.","42350508":"ID: 42350508\nTitle: Gut microbiome diversity across seasons and locations in thai captive Asian elephants (elephas maximus).\nAbstract: The gut health of captive Asian elephants (Elephas maximus) is strongly influenced by human management. However, studies simultaneously examining the effects of both geographical location and season on the gut microbiome of these elephants remain limited. In this study, we focused on two geographically distant and ecologically distinct provinces in Thailand, which differ markedly in management practices, climate, vegetation, and landscape. Fecal samples from 20 to 10 captive Asian elephants in Lampang and Kanchanaburi, respectively, were collected during the wet and dry seasons. The gut microbiome was dominated by the phyla Firmicutes and Bacteroidota across all seasons and locations. Alpha diversity indices indicated that samples from the Lampang-wet group presented the highest diversity, whereas those from the Kanchanaburi-dry group showed the lowest. Beta-diversity analysis revealed significant differences in microbial community structure among the four groups. Functional prediction analysis indicated that microbial metabolic pathways varied between seasons, with carbohydrate metabolism pathways being more enriched in the wet season. Differences in microbiome composition and specific bacterial taxa were observed between samples from Lampang and Kanchanaburi, reflecting the unique management and environmental conditions of each region. Overall, microbial diversity was generally higher during the wet season compared to the dry season.","42351108":"ID: 42351108\nTitle: A magnetic resonance imaging-guided drug delivery system for premetastatic niche theranostics and colorectal cancer liver metastasis intervention.\nAbstract: Colorectal cancer liver metastasis (CRLM) poses a major challenge in cancer theranostics, in which hepatic stellate cell (HSC) activation participates in fibrosis progression and colorectal cancer (CRC) cell recruitment, catalyzing the formation of fibrosis-concomitant premetastatic niche (PMN). Targeting the crosstalk between activated HSCs (aHSCs) and CRC cells, we develop a bioengineered, mesoporous superparamagnetic iron oxide nanoparticle (mSPIONP)-based theranostic nano-system (mSPIONP-Cur@eCM). Camouflaged with CXC chemokine receptor type 4 (CXCR4)-overexpressing CRC cytomembranes, this nano-system exhibits a dual PMN-targeting function, exerting a homologous recognition to CRC cells and anchors to aHSCs with a high secretion of stromal cell-derived factor-1 (SDF-1). Its mSPIONP-Cur core affords not only T2-weighted magnetic resonance imaging (MRI) but also curcumin (Cur) delivery, initiating liver fibrosis detection and metastasis foci delineation, simultaneously blocking the HSC-CRC cell crosstalk by amplifying Cur's therapeutic effect. Verified in fibrosis and CRLM models, mSPIONP-Cur@eCM exhibits great potential for suppressing the fibrosis-concomitant PMN and intervening the CRLM progression.","42352465":"ID: 42352465\nTitle: Cervicovaginal Microbiota and Biogenic Amine Metabolic Shifts in HPV-Associated Cervical Disease.\nAbstract: Background: Cervical cancer is primarily caused by the human papillomavirus (HPV), with persistent infections progressing to low- (LGSIL) and high-grade (HGSIL) lesions. Emerging evidence indicates that the cervicovaginal microbiota influences HPV persistence and disease progression, although the underlying metabolic mechanisms remain unclear. Therefore, we assessed the relationship between the cervicovaginal microbiota and the metabolic milieu in women with cervical dysplasia and HPV infections. Methods: We recruited 36 non-menopausal, non-pregnant women who were classified as negative, LGSIL, or HGSIL based on pathology and HPV results. Cervical swabs were collected for genomic DNA extraction to characterize bacterial communities using 16S rRNA sequencing and to perform HPV genotyping. Cervical lavages were collected for untargeted metabolomic profiling using Gas Chromatography-Mass Spectrometry. Integrative multiomic analysis was performed using the MIMOSA2 pipeline. Results: Although bacterial community structure was not different between groups, women with HGSIL had higher richness and exhibited a higher abundance of Prevotella bivia, Prevotella buccalis, and Lachnospiraceae G-9 oral taxon 924. Lesion-positive samples had shifts in tyramine and putrescine, biogenic amines linked to cancer development. Specifically, Pseudomonas was identified as a potential contributor to tyramine oxidation. Conclusions: Cervical lesions and HPV risk are associated with shifts in the cervicovaginal microbial metabolic milieu, highlighting the role of low-abundant anaerobic bacteria. Despite the small sample size, biogenic amines were associated with anaerobic taxa and microbial dysbiosis. These findings warrant further assessment of microbial-derived metabolites and their potential to promote tumor progression by driving a pro-inflammatory, metabolically altered microenvironment.","42353046":"ID: 42353046\nTitle: Polyphenol-Rich Oenanthe javanica as a Cardioprotective Functional Food Candidate Exhibiting Antiplatelet Activity via Suppression of Ca2+ Mobilization and Thromboxane A2 Production.\nAbstract: Polyphenol-rich Oenanthe javanica (Blume) DC. is widely consumed in Asia but its impact on platelet activation, a cause of cardiovascular disease (CVD), is unclear. Collagen-driven platelet activation requires intracellular Ca2+ mobilization and thromboxane A2 (TXA2) production-rational targets for CVD prevention. A hot water extract of O. javanica (OJWE) was profiled by HPLC and tested on collagen-stimulated washed human platelets. Aggregation, Fura-2 [Ca2+]i, and TXB2 were measured, including combinations with verapamil, aspirin, caffeic acid (CA), and chlorogenic acid (CGA). Coagulation (PT/APTT) and ex vivo effects in Sprague-Dawley rats given OJWE (1 or 5 mg day-1, 30 days) were also evaluated. OJWE dose-dependently inhibited collagen-induced aggregation in a Ca2+-dependent manner, synergizing with verapamil, and suppressed [Ca2+]i mobilization and TXA2 production. CA and CGA synergistically enhanced aspirin-mediated COX-1 inhibition. PT/APTT were unaffected in vitro and ex vivo. Dietary OJWE modestly but significantly reduced rat platelet aggregation without altering coagulation. OJWE attenuates platelet activation by selectively targeting Ca2+ mobilization and TXA2 biosynthesis without compromising hemostasis, supporting O. javanica as a functional food with cardiovascular potential at dietary intake.","42353102":"ID: 42353102\nTitle: Effects of Chlorantraniliprole on Oxidative Stress, Enzymatic Biomarkers, and Hepatic Transcriptome in Alosa sapidissima (Wilson, 1981).\nAbstract: The purpose of this study was to investigate the adverse effects of 1.5 μg·L-1 environmentally relevant chlorantraniliprole (CAP) on oxidase biomarkers (juvenile, 2.5 g) for 2, 4, and 8 h and transcriptomic response (adult, 254.8 g) for 96 and 192 h in American shad Alosa sapidissima (Wilson, 1981). American shad is sensitive to pollutants and has become an important economic fish in China, especially for recirculating the aquaculture system and photovoltaic farming. For juvenile shad under short-time CAP exposure, acid phosphatase (ACP) and aryl hydrocarbon receptase (AHR) at the protein level significantly increased at 2 h, and for longer-time exposure, alkaline phosphatase (AKP), polyphenol oxidase enzyme (PPO), and tumor necrosis factor alpha (TNFα) at the protein level significantly decreased; ryanodine receptase (RYR) at the protein level was significantly increased at 8 h. Interestingly, malondialdehyde (MDA) contents, biomarkers of oxidative stress, were significantly decreased for depletion at 2 h and 4 h, while they increased for eliminating free radicals at 8 h via longer-time CAP exposure duration. With the same CAP exposure for adult shad, the number of congested and dilated sinuses of the liver changed, with fine granular brown pigmentation and vacuolization of hepatocytes at 96 h, while the sinuses and central veins were dilated and edematous degeneration occurred at 192 h for longer-time exposure. The detected enzymatic activities, except for adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK), significantly decreased, and MDA contents significantly increased in adult shad at 96 and 192 h. Ribosome, proteasome, spliceosome, protein processing in endoplasmic reticulum, oxidative phosphorylation, glycerophospholipid metabolism, biosynthesis of amino acids, ferroptosis, peroxisome, apoptosis, necroptosis, and mTOR signaling pathways were the most significantly enriched pathways. For qPCR verification, the genes ppa2, pla1a, psmb13a, pkz and stat1b were significantly upregulated, while hspa8b, capn2, tram2, asns, bcl2l1, diablo, and prkcb were downregulated in adult shad. The results reveal elevated oxidative stress causing time-dependent hepatic damage via 1.5 μg·L-1 CAP exposure both in juvenile and adult shad.","42353167":"ID: 42353167\nTitle: Fecal Extracellular Vesicle Metabolomics as a Non-Invasive Biomarker Source in Colorectal Cancer: TPOT AutoML Superiority over Tree-Based Models with SHAP and LIME Clinical Interpretability.\nAbstract: Colorectal cancer (CRC) remains one of the leading causes of cancer-related mortality worldwide, highlighting the critical need for non-invasive, accurate, and interpretable diagnostic tools. Metabolomic profiling of fecal microbial extracellular vesicles (EVs) offers a promising yet underexplored avenue for biomarker discovery when integrated with explainable machine learning (ML) frameworks. This study aimed to identify stool-derived microbial EV metabolite biomarkers that discriminate CRC patients from healthy controls and to develop interpretable ML classifiers for non-invasive CRC detection. Metabolomic profiles of fecal microbial EVs from 76 age- and sex-comparable participants (36 CRC, 40 controls) were obtained using LC/QTOFMS and GC/TOFMS. Three ML classifiers (TPOT, LightGBM, XGBoost) were trained and evaluated through 100-repeat stratified hold-out and nested 5-fold cross-validation, with SHAP and LIME applied for global and local interpretability. Fourteen metabolites were significantly dysregulated between the CRC and control groups (adjusted p < 0.05), with 13 upregulated and one (aminoisobutyric acid) downregulated. Furoic acid exhibited perfect diagnostic discrimination, followed by palmitic acid and tyramine. Nested cross-validation demonstrated robust performance: TPOT achieved AUC = 0.997 ± 0.005, sensitivity = 0.973 ± 0.022, and MCC = 0.957 ± 0.033. Hold-out validation corroborated these findings (AUC = 0.998 ± 0.008). SHAP analysis identified furoic acid, palmitic acid, and tyramine as the dominant predictive features, while aminoisobutyric acid exhibited a distinctive protective pattern. LIME analysis corroborated these findings at the individual prediction level. The identified fecal EV-derived metabolite panel-particularly furoic acid, palmitic acid, and tyramine-shows strong potential to predict CRC in a non-invasive, interpretable manner; however, given the modest sample size, these findings should be considered hypothesis-generating and require validation in larger, prospective, multi-center cohorts before clinical translation.","42353529":"ID: 42353529\nTitle: Effects of Different Rearing Systems (Cage vs. Free-Range) on Growth Performance, Serum Biochemical Parameters, Slaughter Performance, Cecal Microbiota, and Hepatic Metabolism of Yellow-Feathered Broilers.\nAbstract: This experiment investigated the effects of two rearing systems, cage and free-range, on growth performance, serum biochemical parameters, slaughter performance, cecal microbiota, and hepatic metabolism of yellow-feathered broilers. A total of 240 healthy 21-day-old Liangfenghua yellow-feathered male broilers with similar body weight were randomly assigned to a cage group (LY) and a free-range group (SY), with 10 replicates per group and 12 birds per replicate. All birds were fed the same diet until 63 days of age. Compared with the LY group, the SY group had significantly lower final body weight, average daily gain, and abdominal fat percentage (p < 0.05), while average daily feed intake and feed-to-gain-ratio were significantly higher (p < 0.05). The Shannon and Simpson indices of the cecal microbiota were significantly higher in the SY group (p < 0.05), and the genera Bacteroides, Lactobacillus, Rikenella, and Oscillibacter were specifically enriched. A total of 560 differential metabolites were identified by liver non-targeted metabolomics, and these metabolites were significantly enriched in the necroptosis, cysteine and methionine metabolism, thiamine metabolism, and amino sugar and nucleotide sugar metabolism pathways (p < 0.05). Correlation analysis between cecal microbiota and liver metabolites revealed that the differentially abundant bacterial genera showed significant negative correlations with multiple amino acid metabolites in the liver. In conclusion, the free-range rearing system reduced the growth performance of yellow-feathered broilers but enriched specific bacterial genera, increased gut microbiota diversity, and modulated host amino acid metabolism and energy homeostasis through the \"gut microbiota-liver\" axis, ultimately inducing an adaptive metabolic state characterized by reduced abdominal fat deposition and remodeling of hepatic metabolic pathways.","42356255":"ID: 42356255\nTitle: The Associations of Trunk Intramuscular Adipose Tissue Content with Dietary Intake and Eating Behavior in Younger and Older Japanese Women: A Pilot Study.\nAbstract: Background/Objectives: Intramuscular adipose tissue (IntraMAT) is the ectopic fat which accumulates within skeletal muscle. The relationship between trunk IntraMAT content and dietary intake was shown to differ with age in men, but it remains unclear the relationship in women. Therefore, the present study investigated the associations of IntraMAT content with dietary intake and eating behavior in younger and older women. Methods: This cross-sectional study involved 24 young women aged 18 to 23 years (body mass index (BMI): 20.5 ± 2.3 kg/m2) and 25 older women aged 66 to 77 years (BMI: 21.7 ± 2.5 kg/m2) who participated. IntraMAT content was assessed by magnetic resonance imaging at the height of the 3rd lumbar vertebra. Dietary intake was evaluated using a self-administered diet history questionnaire. Eating behavior was evaluated by scores calculated using the eating behavior questionnaire in the guideline for obesity (2022). Blood properties related to metabolic syndrome were also measured. Results: In the younger group, IntraMAT content was significantly related to HDL cholesterol and insulin (rs = -0.411 and 0.415, p < 0.05). In the older group, IntraMAT content significantly correlated with the percentage of energy from protein, sense of hunger, and total eating behavior (rs = -0.410 to 0.412, p < 0.05). Conclusions: Trunk IntraMAT content may be related to dietary protein intake and eating behavior in the older group.","42356262":"ID: 42356262\nTitle: Beneficial Effects of Spermidine on Ovarian Function, Gut Microbiota Composition, and Associated Metabolic Changes.\nAbstract: Spermidine is involved in a wide range of cellular processes, including mammalian oocyte development. Wheat germ is a natural source of polyamines and contains high concentrations of spermidine. However, no studies have evaluated the effects of wheat germ-derived spermidine on the regulation of mammalian ovarian function. The present study aimed to investigate the effect and underlying mechanism of wheat germ-derived spermidine on mammalian ovarian function. A feeding trial was carried out on mice with diets supplemented with varying concentrations of spermidine. The underlying mechanism by which spermidine exerts its beneficial effects on ovarian function and fertility in mice was explored through the integration of serum metabolomics and intestinal microbiomics analyses. The results showed that dietary spermidine-rich feed significantly increased spermidine absorption and affected the metabolism of spermine and putrescine in the intestines. Dietary intake of low-concentration spermidine significantly increased the number of pups per litter and the secretion levels of estradiol (E2), progesterone (P4), luteinizing hormone (LH), and anti-Müllerian hormone (AMH). Furthermore, compared with a normal diet, spermidine supplementation resulted in significantly higher ovarian reserves and fewer atretic follicles. Correspondingly, metabolomics analysis revealed that spermidine primarily affected lipid metabolism and endocrine functions related to reproduction. In addition, dietary spermidine significantly altered the structural composition of the gut microbiota. Correlation analysis demonstrated that the abundance of Oceanisphaera, Atopostipes, and Actinobacteriota was significantly positively correlated with the secretion of E2, P4, and LH. Overall, these findings yield phenotypic insights into spermidine's mediation of mammalian reproductive performance and offer a potential therapeutic strategy for individuals with reproductive dysfunction.","42356272":"ID: 42356272\nTitle: Effects of 12-Week Sorghum Consumption on Visceral Fat Area and Metabolic Parameters in Japanese Adults: An Exploratory Single-Arm Trial.\nAbstract: Background: Visceral fat accumulation is strongly associated with metabolic disorders, particularly in Japanese adults who accumulate visceral fat even at lower body mass index levels. Sorghum is a whole grain rich in resistant starch and polyphenols, which may influence visceral fat area (VFA). This exploratory study aimed to investigate the effects of 12-week sorghum consumption on VFA and metabolic parameters in Japanese adults with visceral fat accumulation. Methods: This single-arm intervention trial included adults aged 20-60 years with VFA ≥ 100 cm2 and no ongoing medical treatment. Participants consumed cooked sorghum (80 g/day, dry weight) for 12 weeks. Anthropometric variables, VFA, blood pressure, and blood biomarkers were assessed before and after the intervention. Dietary intake was evaluated using a three-day food record. Pre- and post-intervention values were compared using paired t-tests. Results: Nine participants completed the study. VFA significantly decreased after 12 weeks of sorghum consumption (p = 0.02). Alanine aminotransferase (ALT) levels showed a non-significant reduction, while other metabolic and hepatic biomarkers remained stable. No adverse changes were observed in dietary intake or physical activity. Eight of nine participants exhibited reductions in VFA. Conclusions: Daily sorghum consumption may contribute to reductions in VFA and improvements in liver-related biomarkers in Japanese adults with visceral fat accumulation. These findings provide preliminary evidence that partially replacing major carbohydrate sources with sorghum may support visceral fat management. Further confirmation in randomized controlled trials is warranted.","42356299":"ID: 42356299\nTitle: Diet-Microbiota-Immune Interactions in Hepatocellular Carcinoma: An Immunometabolic and Spatial Perspective.\nAbstract: Hepatocellular carcinoma (HCC) is the most frequent type of primary liver cancer and one of the leading causes of cancer-related mortality globally, with its incidence increasingly driven not only by viral hepatitis and alcohol-related etiologies but also by metabolic dysfunction-associated steatotic liver disease. Dietary intake can modify gut microbial activity and the production of microbial metabolites, which in turn may regulate hepatic immune signaling and metabolic pathways along the gut-liver axis. Microbiota-derived metabolites have emerged as important immunometabolic mediators linking dietary factors to hepatic immune responses and metabolic reprogramming. These metabolites, which have been shown to influence hepatic immune cell function and inflammatory signaling, include short-chain fatty acids, secondary bile acids, and tryptophan-derived indoles. Changes in the production and composition of these metabolites have been associated with immune dysregulation, chronic inflammation, and metabolic reprogramming that promote hepatocellular carcinoma development. This review highlights how diet-microbiota interactions reshape hepatic immunometabolism and discusses their potential translational relevance for prevention and therapeutic strategies in hepatocellular carcinoma.","42356353":"ID: 42356353\nTitle: Nutritional Monitoring During Gender-Affirming Hormone Therapy: Body Composition and Metabolic Implications.\nAbstract: Background/Objectives: Gender-affirming hormone therapy (GAHT) is associated with clinically relevant changes in body composition, energy metabolism, and functional capacity in transgender and gender-diverse individuals. The nutritional implications of these adaptations remain insufficiently characterized, and current assessment models, largely derived from cisgender populations, may not fully capture hormone-related body composition and metabolic changes. This narrative review aims to synthesize the metabolic and body composition effects of GAHT, evaluate methodological limitations in assessing nutritional status, and propose an integrated framework for clinical nutritional management. Methods: A narrative literature review was conducted through searches of PubMed/MEDLINE, Scopus, and Web of Science, complemented by screening of relevant guidelines and reference lists. Priority was given to longitudinal studies, mechanistic studies, systematic reviews, meta-analyses, and clinical guidance addressing GAHT-related changes in body composition, metabolism, nutritional status, and functional outcomes. Results: Available evidence suggests that GAHT is associated with sex steroid-related, tissue-specific changes in body composition and metabolism. In transgender men, testosterone is generally associated with increases in lean body mass (LBM), reductions in fat mass, and potential increases in visceral adiposity, alongside possible increases in energy expenditure and altered cardiometabolic profiles. In transgender women, estrogen therapy, combined with androgen suppression, is generally associated with reductions in LBM and redistribution of subcutaneous fat, with heterogeneous metabolic and functional responses. Across both groups, changes in body composition are not consistently reflected by the Body Mass Index or functional outcomes, suggesting a possible dissociation between structural and functional adaptation. Common assessment tools show limitations, including reliance on cisgender-derived reference standards and inability to capture dynamic hormonal transitions. Conclusions: Current evidence supports the need for a longitudinal and individualized interpretation of nutritional and body composition changes during GAHT. A shift toward longitudinal, multimodal nutritional assessment, integrating body composition, functional measures, biochemical markers, dietary intake, and clinical context, may improve clinical monitoring and reduce misclassification.","42356402":"ID: 42356402\nTitle: Preliminary Assessment of Red Beetroot Supplementation and Cultivar Effects in Low-Protein-Fed WKY Rats.\nAbstract: Background/Objectives: Red beetroot (Beta vulgaris L.) is recognized for its antioxidant, anti-inflammatory, and metabolic properties. This study evaluated the effects of two beetroot cultivars (Boldor and Wodan) on blood serum parameters, body composition, and organ weights in male WKY rats fed a low-protein diet (LPD, 8.8% protein). Methods: Five-week-old male rats were maintained on an LPD for 8 weeks and subsequently continued on the LPD diet supplemented with 4% dried beetroot for 45 days. The experimental diets included beetroot from the Boldor and Wodan cultivars, either treated or untreated with a plant growth stimulator during cultivation. Results: Foliar application of the selenium-based plant growth stimulator did not significantly increase selenium or other element concentrations in beet roots. Elemental analysis showed higher levels of Fe, Zn, Cu, Cr, Pb, As, Cd, and Sb in the Wodan group, while Boldor increased Cr, Pb, and As; Ni and Se remained unchanged. Beetroot supplementation significantly affected 14 of the 30 measured biochemical parameters, including biomarkers of liver function (ALT, ALP, total bilirubin, albumin, and total protein), renal function (uric acid), pancreatic activity (amylase and lipase), electrolyte balance (sodium, potassium, and chloride), mineral metabolism (calcium), inflammatory status (CRP), and nutritional metabolism (iron). Conversely, no significant effects were observed on lipid profile parameters or biomarkers of cardiac and skeletal muscle injury. Among the beetroot cultivars evaluated, Wodan exerted distinct effects relative to Boldor, resulting in higher circulating total bilirubin and potassium concentrations, alongside reduced uric acid and lipase levels in treated rats. Boldor supplementation significantly increased body weight gain and fat mass, with a trend toward higher lean mass, and increased kidney weight. Wodan did not significantly affect body weight but increased kidney and spleen mass. Feed intake was similar across groups. No changes in cardiovascular function were observed ex vivo. Conclusions: Beetroot supplementation modulated multiple metabolic and physiological biomarkers in rats fed a low-protein diet, with distinct cultivar-specific effects, underscoring the importance of cultivar selection for optimizing functional dietary interventions.","42356741":"ID: 42356741\nTitle: A CNN-MAMBA-Based Framework for Salient Bowel Sound Detection and Gastrointestinal Health Assessment.\nAbstract: With the rapid aging of the global population, constipation has become a major gastrointestinal concern among elderly individuals. Bowel sounds provide a non-invasive acoustic signal for assessing gastrointestinal function, but their automatic analysis remains challenging due to sparsity and non-stationarity. This study proposes a two-stage bowel sound analysis framework based on continuous abdominal recordings. First, a Convolutional Neural Network-MAMBA (CNN-MAMBA) model was used for salient bowel sound detection. Second, a patient-level constipation classification model was developed using multi-view spectral representations and a Convolutional Neural Network-Conformer-Multiple Instance Learning (CNN-Conformer-MIL) architecture. On a held-out test set, the detection model achieved an accuracy of 0.87, an F1-score of 0.78, and a ROC-AUC of 0.93. For patient-level classification under binary Bristol Stool Form Scale (BSFS) grouping, five-fold cross-validation yielded a mean accuracy of 0.665 and an F1-score of 0.755. All BSFS labels were annotated by clinical physicians and temporally aligned with bowel sound recording. Given the modest improvement and cross-validation variability, the patient-level results should be interpreted as preliminary feasibility evidence. These findings suggest that bowel sound analysis may serve as an auxiliary screening or longitudinal monitoring tool rather than a stand-alone diagnostic system.","42358203":"ID: 42358203\nTitle: Interplay of Mitochondrial Dynamics, Nutrition, and Vitamins: Evidence From Experimental and Human Studies With Implications for Women's Health.\nAbstract: Nutrition is a key modifiable factor supporting mitochondrial health and is essential for ovarian function and women's health across the life course. From menarche to menopause, mitochondrial efficiency underpins physiological balance. The menopausal transition is particularly critical, as hormonal and neuroendocrine changes are associated with impaired mitochondrial function and increased risk of age-related disorders. This review aimed to systematically review and synthesize the available evidence on mitochondrial function across in vitro, animal, and human studies and to evaluate the potential protective role of vitamins and nutrients in maintaining mitochondrial health, with attention to sex-specific findings. A systematic search was conducted across multiple electronic databases. Forty-six eligible studies were identified and critically reviewed for evidence on mitochondrial function, sex-based differences, and nutritional influences. Mitochondrial dysfunction may contribute to the pathophysiology of age-related disorders, including osteoporosis, cardiovascular disease, neurodegenerative conditions, and cancer. Nutritional factors are crucial for preserving mitochondrial integrity. Vitamins C, E, and D, NAD + precursors such as nicotinamide riboside, coenzyme Q10, MitoQ, fucoxanthin, and cabergoline reduce oxidative stress, enhance mitochondrial biogenesis, support electron transport chain activity and ATP production, and maintain redox balance. These actions promote mitochondrial resilience and cellular energy metabolism. Evidence further indicates that women, particularly during the menopausal transition, exhibit heightened vulnerability to mitochondrial dysfunction, highlighting the relevance of nutrition-based interventions. Optimizing dietary intake of vitamins, antioxidants, and mitochondrial cofactors is a cost-effective, accessible strategy to support mitochondrial health and reduce age-related disease risk in women.","42360906":"ID: 42360906\nTitle: In vitro evaluation of monoamine oxidase and acetylcholinesterase enzyme activities of Capparis cartilaginea Decne.\nAbstract: The genus Capparis is recognised for its neuroprotective potential; however, the biological activity of Capparis cartilaginea Decne. (C. cartilaginea) remains insufficiently explored. This study evaluated the in vitro inhibitory activity of the combined fractions of C. cartilaginea leaves and their isolated flavonoids against monoamine oxidase A (MAO-A) and B (MAO-B) using liver and brain mitochondrial preparations. The fractions inhibited both isoforms in a concentration-dependent manner, with the most pronounced MAO-B inhibition observed in liver mitochondria (97.9% at 2.0 mg/mL), exceeding the activity of the reference inhibitor deprenyl (91.8%). Among the isolated flavonoids, narcissin exhibited the strongest MAO-B inhibition (Ki = 0.34 ± 0.06 μmol/L), followed by rutin, manghaslin, and nicotiflorin. No significant acetylcholinesterase (AChE) inhibition was detected. These findings suggest that C. cartilaginea and its flavonoid constituents represent promising leads for the development of MAO-B-targeted neuroprotective agents.","42361946":"ID: 42361946\nTitle: Dose- and time-dependent dissemination of viable Leishmania amazonensis following experimental footpad infection in mice.\nAbstract: Cutaneous leishmaniasis is typically characterized by localized skin lesions, but the extent to which Leishmania amazonensis disseminates beyond the primary site of infection remains incompletely defined. In this study, BALB/c mouse footpads were infected subcutaneously with L. amazonensis promastigotes at doses ranging from 105 to 108, and infection was evaluated over time up to 120 days. All infected groups developed local footpad infection, and amastigotes were detectable at the infection site early after challenge. Footpad swelling and parasite burden increased progressively, with more pronounced local lesion development observed at higher infective doses. At an infective dose of 1 × 106, viable parasites were recovered predominantly from the footpad and bone marrow, with only limited detection in the spleen at later time points. In contrast, infection with 1 × 108 promastigotes resulted in broader dissemination, with viable parasites detected in the bone marrow and spleen and, at later stages of infection, in the liver and peripheral blood. Parasite-specific IgG, IgG1, and IgG2a antibody responses were also higher in the 1 × 108 infection group than in the 1 × 106 group. These findings show that experimental L. amazonensis infection is not uniformly restricted to the skin and that viable parasite dissemination to non-cutaneous tissues is influenced by inoculum size and infection duration.","42364637":"ID: 42364637\nTitle: The effects of T-2 toxin on hepatic cytochrome P450 and carboxylesterase enzymes in mice: Evidence as changes in their expression, activity, and transcriptomic profiles.\nAbstract: T-2 toxin, a highly toxic trichothecene mycotoxin contaminating cereal grains, poses serious health threats. However, its specific effects on hepatic drug-metabolizing enzymes (DMEs) remain poorly characterized. This study aimed to investigate the impact of T-2 toxin on key cytochrome P450 (CYP) and carboxylesterase (CES) enzymes in mouse liver. Male C57BL/6 mice were randomly divided into control and T-2 toxin-treated groups, receiving either normal saline or T-2 toxin (0.2 mg/kg) by oral gavage daily for four weeks. Histopathological and ultrastructural alterations were assessed by hematoxylin and eosin staining and transmission electron microscopy. The activity, mRNA, and protein levels of target enzymes in liver tissues or AML12 cells were determined via enzymatic assays, quantitative real-time PCR (qRT-PCR), and western blotting. Transcriptomic profiling (RNA-seq) was performed to identify differentially expressed genes (DEGs) and enriched pathways. T-2 toxin exposure induced hepatocellular injury, including focal necrosis and mitochondrial damage. It significantly altered the activity and expression of multiple phase I DMEs, notably CYP1A2, CYP2B10, CYP3A11, and CES isoforms, at both transcriptional and protein levels. Transcriptomic analysis identified 277 DEGs, predominantly enriched in xenobiotic and drug metabolism pathways, including drug metabolism-cytochrome P450 and xenobiotic metabolic process. T-2 toxin induces hepatotoxicity and concurrently alters the expression and activity of key hepatic DMEs. These findings provide insight into T-2 toxin-induced disturbances in xenobiotic metabolism and may contribute to future studies on metabolic biomarkers and toxicological mechanisms.","42367759":"ID: 42367759\nTitle: Establishment of a laboratory mouse model to study Borrelia miyamotoi infection and disease.\nAbstract: Borrelia miyamotoi is an emerging relapsing fever spirochete transmitted by Ixodes spp. ticks that serve as vectors for other human pathogens, including the agents of Lyme disease. To date, an animal model to study tick-borne B. miyamotoi infection and pathology has not been reported. Here, we describe the development of a laboratory mouse model of infection using clinical isolate CT14D4 derived from the blood of a Connecticut resident with disseminated Lyme disease. Genomic analysis revealed that the CT14D4 genome was similar to other B. miyamotoi strains isolated from Ixodes scapularis ticks in the eastern United States. We show that CT14D4 can be propagated in mice by needle inoculation and through a tick-mouse infection cycle. Relapsing spirochetemia was observed in wild-type (WT), Myd88 -/-, and splenectomized mice, all of which eventually cleared the infections. In contrast, Rag1 -/- mice lacking B and T cells remain persistently bacteremic. WT mice that had cleared CT14D4 infection are resistant to reinfection with this B. miyamotoi strain. Spirochetes were visualized in several organs after perfusion fixation of infected Rag1 -/- mice, including the brain, with histopathology revealing extramedullary hematopoiesis and inflammatory infiltrates that were most pronounced in the liver. WT mice exhibited similar but milder pathology during periods of bacteremia. These studies provide a useful model to study hard-tick relapsing fever pathogenesis and disease.","42367940":"ID: 42367940\nTitle: FALCON: Closed-Loop Multi-Objective Optimization of Lipid Nanoparticles for Cell-Selective mRNA Delivery.\nAbstract: Efficient, cell type-selective delivery of genetic payloads remains a central challenge in the development of gene and cell therapies. Lipid nanoparticles (LNPs) offer a versatile delivery platform, but their optimization is hindered by reliance on brute-force screening methods that are laborious, resource-intensive, and focus on single targets. Here, we present FALCON (Framework for Active Learning-driven Compositional Optimization of Nanoparticles), a closed-loop pipeline that leverages iterative screening, surrogate modeling, and multi-objective optimization to accelerate LNP compositional design. In B cell-targeted validation experiments, FALCON-optimized LNPs achieved a 1.8-fold increase in splenic B cell transfection in vivo compared with reference compositions. When optimized for selectivity, FALCON LNPs displayed an 84-fold improvement in selective transfection of splenic B cells over off-target liver populations and enabled spleen-tropic behavior across factorial panels of varying ionizable and helper lipid chemistries. In vaccine studies, these LNPs induced higher IgG2c antibody titers and a more Th1-biased immune profile. FALCON was also deployed to optimize LNPs for myeloid cell-selective delivery, achieving enhanced in vivo selectivity following systemic administration both across and within spleen and liver compartments. Our results establish FALCON as a useful tool for data-driven design of LNP compositions for precision gene delivery.","42370768":"ID: 42370768\nTitle: Idiopathic anaphylaxis and histamine dysregulation: Revisiting pathophysiologic assumptions.\nAbstract: Idiopathic anaphylaxis (IA) is a diagnosis of exclusion, and the etiology remains elusive.

Time-restricted eating (TRE) has emerged as a promising dietary strategy for improving metabolic health. Although both early time-restricted eating (eTRE) and mid-day time-restricted eating (mTRE) have shown beneficial metabolic effects, their comparative efficacy in women with PCOS remains unclear. This study aimed to directly compare the effects of eTRE and mTRE on glycemic control, lipid profiles, and anthropometric outcomes in women with PCOS. In this 6-week randomized controlled trial, 75 women with PCOS were allocated to one of three groups: eTRE (8:00 AM-6:00 PM), mTRE (11:00 AM-9:00 PM), or a control group with ad libitum eating. The primary outcome was fasting insulin level. Secondary outcomes included FBS, insulin resistance indices, lipid profile (total cholesterol (TC), LDL-C, HDL-C, and TG), body weight, BMI, waist circumference (WC), and dietary intake. Metabolic and anthropometric variables were assessed at baseline and post-intervention, while dietary intake was evaluated at baseline, mid-intervention, and study completion. Both eTRE and mTRE significantly reduced FBS, fasting insulin, Homeostasis Model Assessment of Insulin Resistance (HOMA-IR), body weight, and WC compared with the control group (P < 0.05). Additionally, eTRE significantly improved TC (P < 0.001) and LDL-C levels (P = 0.01), whereas similar changes were not observed in the mTRE group. TRE, particularly eTRE, appears to be an effective dietary intervention for women with PCOS, offering significant benefits for glycemic control, metabolic health, and weight management.

Routine blood-count-based inflammatory indices may complement established liver reserve assessments. This study evaluated whether preoperative systemic pan-immune-inflammation value (S-PIV) predicts PHLF after conventional laparoscopic hepatectomy for HCC. We conducted a single-center retrospective cohort study of consecutive patients who completed conventional laparoscopic hepatectomy for liver tumors between January 2017 and December 2025. Eligible patients had pathologically confirmed HCC and complete preoperative laboratory data within 7 days before surgery. Planned open hepatectomy, conversion to open surgery, and robotic-assisted hepatectomy were outside the predefined cohort scope. S-PIV was calculated as neutrophil count × monocyte count × platelet count / lymphocyte count. The primary outcome was ISGLS-defined PHLF, analyzed as any-grade PHLF versus no PHLF. Discrimination was assessed using ROC analysis, dose-response using restricted cubic splines, and clinical utility using decision curve analysis. Among 582 screened patients, 356 were included; 68 (19.1%) developed PHLF. Preoperative S-PIV showed good discrimination for PHLF (AUC 0.873). The Youden index identified an optimal cut-off of 455.4, with sensitivity 0.726 and specificity 0.908. S-PIV showed higher AUCs than NLR (0.831) and PLR (0.848). Higher S-PIV was associated with PHLF in univariable analysis (per 100 units: OR 1.12, 95% CI 1.06-1.45; P<0.001) and remained independently associated after sequential adjustment for demographics/comorbidities, liver functional reserve, and tumor/operative factors (Model 3 per 100 units: OR 1.06, 95% CI 1.03-1.13; P<0.001). Restricted cubic splines showed a graded risk increase without evidence of nonlinearity, and decision curve analysis suggested net benefit across threshold probabilities of approximately 10%-70%. Preoperative S-PIV, derived from routine blood counts, may serve as a practical adjunct for PHLF risk stratification after conventional laparoscopic hepatectomy for HCC. External multicenter validation and calibration are urgently required before routine implementation. Liver surgery can help many patients with liver cancer, but some patients may have poor liver function after part of the liver is removed. This problem can slow recovery and may become serious. Doctors therefore need simple ways to identify patients who may need closer care before and after surgery. In this study, we reviewed people with this type of liver cancer who had laparoscopic liver surgery at our hospital. We tested whether information from a routine blood test before surgery could help estimate the chance of liver failure after surgery. This blood test reflects the balance between inflammation and immune status in the body. We found that patients with a higher inflammation-related blood score before surgery were more likely to develop liver failure after surgery. This score may help doctors discuss surgical risk with patients, plan perioperative care, and identify patients who may need closer monitoring after surgery. These findings are promising, but they come from one hospital. More studies from multiple hospitals are needed before this blood score can be used routinely in clinical practice. What do the terms mean? The terms used in this article are explained in plain language as follows. Hepatocellular carcinoma refers to the most common type of primary liver cancer. Laparoscopic liver surgery refers to liver surgery performed through small cuts in the abdomen using a camera and surgical instruments. Liver failure after surgery refers to a condition in which the remaining liver does not work well enough after part of the liver has been removed. A blood inflammation score is calculated from routine blood cell counts and reflects inflammation and immune status. Liver reserve refers to the ability of the liver to keep working after surgery. Closer monitoring means more careful observation and follow-up before and after surgery. Multicenter validation means testing the findings in patients from other hospitals to confirm whether the results are reliable.","42371749":"ID: 42371749\nTitle: Genetic Determinants of Macronutrient Intake Are Associated With Specific Food Intake in Youth: A Cohort Study Across Childhood and Adolescence.\nAbstract: We examined associations of polygenic scores (PS) for macronutrient intake with food intake and cardiometabolic outcomes during childhood and adolescence and evaluated gene enrichment in hypothalamic cell types. We derived carbohydrate, fat, and protein intake PS from an adult genome-wide association study among 516 non-Hispanic White children from the Project Viva cohort. We estimated dietary intake and calculated BMI z scores from measured height and weight at ages ∼3, 8, 13, and 18 years. Waist circumference, truncal fat, fasting glucose, insulin, glycated hemoglobin, and blood lipids were measured at 18 years. We estimated associations of PS with sugar-sweetened beverages (SSB), fast food, and BMI z score using generalized estimating equations (longitudinal), and using regression models for cardiometabolic and secondary dietary outcomes (cross-sectional). We evaluated enrichment of macronutrient intake genetic signals in hypothalamic cell types in the Human HYPOMAP data set. A 1-SD increase in carbohydrate PS was associated with higher odds of consuming two or more servings per week of SSB (odds ratio [OR] 1.20; 95% CI 1.07, 1.33) and one or more times per week of fast food (OR 1.11; 95% CI 1.004, 1.23) from ages 3 to 18 years. Higher-protein PS was associated with lower odds of consuming SSB (OR 0.84; 95% CI 0.75, 0.93). We did not observe consistent associations between macronutrient intake PS and cardiometabolic outcomes. We observed hypothalamic regional and neurotransmitter-specific patterns of gene enrichment for carbohydrate or protein intake. Genetic susceptibility for carbohydrate intake is associated with SSB and fast-food consumption in youth. Underlying pathways relating to hypothalamic nutrient-specific appetite signaling may be involved.","42374630":"ID: 42374630\nTitle: Hypogin-derived N-cinnamoylated peptide as a promising green fungicide against peanut southern blight caused by Sclerotium rolfsii.\nAbstract: Peanut southern blight, caused by Sclerotium rolfsii, severely reduces yield and quality. The overuse of chemical fungicides accelerates resistance development and raises environmental concerns, highlighting the necessity for eco-friendly alternatives. Hypogin is an endogenous peanut peptide with broad-spectrum antifungal activity. This study aims to identify the active centers of hypogin and evaluate the antifungal activity and preliminary mechanisms of its derived peptides. Seven hypogin-derived peptides (series I) and two cinnamic acid conjugates (series II) were synthesized. Among these, II-1 (cinnamic-KSPY-NH2) demonstrated the highest in vitro activity against S. rolfsii, with a half-maximal effective concentration value of 257.93 mg/L. In vivo studies revealed that II-1 provided superior curative efficacy (66.47%) against peanut southern blight, surpassing the commercial fungicide polyoxin (57.33%), and also promoted root growth in peanuts. Both I-7 and II-1 exhibited low cytotoxicity toward human LO2 liver cells, with inhibition rates of 5.05% and 17.44%, respectively, at a concentration of 400 mg/L. Preliminary mechanistic investigations indicated that I-7 specifically targets the Vps34 signaling pathway in S. rolfsii. Hypogin-derived peptide II-1 exhibits significant antifungal activity and low toxicity, making it a promising candidate for a green fungicide in the management of peanut southern blight. © 2026 Society of Chemical Industry.","42375102":"ID: 42375102\nTitle: Transcriptomic Analysis Reveals Multilayer Regulation Underlying Development and Pregnancy in the Malayan Pangolin.\nAbstract: The critically endangered Malayan pangolin (Manis javanica) exhibits distinctive physiological adaptations; nevertheless, its molecular mechanisms underlying development and reproduction remain inadequately characterized, thereby impeding effective conservation initiatives. In this study, we conducted a comprehensive transcriptomic analysis of six tissues (intestine, kidney, liver, lung, muscle, and spleen) derived from adult, fetal, and pregnant individuals. The fetal stage demonstrated the greatest abundance of stage-specific genes, which were predominantly enriched in developmental pathways such as epithelial organization and transmembrane signaling. Differential gene expression (DGE) analysis revealed that genes upregulated in adults were primarily associated with metabolic and immune functions, whereas those upregulated in fetuses were linked to developmental processes and cell cycle regulation. Co-expression network analysis identified critical hub genes, including GLDC in adults and NCAM1 in fetuses, that are implicated in stage-specific regulatory mechanisms. Additionally, extensive differential alternative splicing (DAS) events were observed, with exon skipping (SE) representing the most frequent splicing pattern. Integrative analyses suggested that DGE and DAS largely constitute independent regulatory layers; however, a subset of hub genes, such as OBSL1 and TNIP1, exhibited concurrent differential expression and splicing, indicating their potential central roles in coordinating developmental processes. This study presents a detailed transcriptomic atlas of Malayan pangolin development and pregnancy, providing candidate biomarker genes for evaluating reproductive health and developmental status, thereby informing future conservation strategies.","42375567":"ID: 42375567\nTitle: Resveratrol Attenuates Obesity by Inducing GDF15 Expression via the p38-ATF3 Signaling Pathway.\nAbstract: Resveratrol, a natural polyphenol, has been widely studied for its potential health benefits in obesity treatment, but its molecular mechanism remains elusive. This study investigates the molecular mechanisms by which resveratrol promotes the expression and secretion of Growth Differentiation Factor 15 (GDF15), a key regulator of energy homeostasis. Using both murine embryonic fibroblasts (MEFs) and human HepG2 cells, resveratrol dose-dependently upregulates Gdf15 mRNA and protein expression, as well as increases GDF15 secretion. Transcriptome analysis and subsequent validation experiments revealed that Activating Transcription Factor 3 (ATF3) mediates the effect of resveratrol on GDF15 expression. Additionally, resveratrol-treated mice exhibited resistance to high-fat diet-induced obesity and increased plasma GDF15 levels. In vivo studies in mice further confirmed that resveratrol treatment elevates GDF15 levels in liver, kidney, and colon tissues, and enhances downstream ERK signaling in the brain. Collectively, these findings suggest that GDF15 plays a critical role in mediating the anti-obesity effects of resveratrol.","42380072":"ID: 42380072\nTitle: TAAR1-Associated Trace Amines for Cutaneous Nociceptive Blockade in Rats.\nAbstract: This study aimed to evaluate whether TAAR1 (trace amine-associated receptor 1)-associated trace amines (β-phenylethylamine, tryptamine, octopamine, tyramine, and N-methyltyramine) produced cutaneous nociceptive blockade compared to lidocaine. Cutaneous nociceptive blockade was assessed by inhibition of the cutaneous trunci muscle reflex in response to local noxious stimuli. After subcutaneous injection in rats, the nociceptive blockade produced by β-phenylethylamine, tryptamine, octopamine, tyramine, and N-methyltyramine was compared. We demonstrated that, at a dose of 255.3 μmol/kg, β-phenylethylamine, tryptamine, octopamine, tyramine, and N-methyltyramine produced cutaneous nociceptive blockade. At the ED50 (50% effective dose), the relative potency of β-phenylethylamine (85.5 [87.5-93.2] μmol/kg) was lower than that of lidocaine (17.7 [14.6-2.15] μmol/kg; p < 0.01). On an equianesthetic basis (ED25, ED50, and ED75), β-phenylethylamine exhibited a duration of action similar to that of lidocaine. The addition of clonidine or epinephrine did not prolong the duration of action of β-phenylethylamine, whereas the addition of clonidine or epinephrine prolonged the duration of action of lidocaine. Among these five TAAR1-associated trace amines, β-phenylethylamine was the most potent for producing cutaneous nociceptive blockade, tryptamine and octopamine were moderately potent, and tyramine and N-methyltyramine were the least potent. Although β-phenylethylamine was less potent than lidocaine, it exhibited a similar duration of action. Clonidine and epinephrine did not prolong the duration of action of β-phenylethylamine.","42380122":"ID: 42380122\nTitle: Genetically modulating the RNA-binding protein Regnase-1 reveals its critical role in regulatory T cell homeostasis and function in vivo.\nAbstract: Regnase-1 is a CCCH-type RNA-binding protein that constantly degrades mRNA species via its ribonuclease domain to maintain immune quiescence. But how and by what mechanisms Regnase-1 regulates Foxp3+ Tregs remains poorly studied. Here, we generated a conditional knock-in strain in which a degradation-resistant Regnase-1 mutant (R111A) was selectively expressed in Foxp3+ Tregs as a transgene (Foxp3YFP-CreLSL-R111Afl/fl) to investigate the roles of Regnase-1 in Tregs. We found that all male Foxp3YFP-CreLSL-R111Afl/fl mice died of fatal autoimmune diseases by 4 weeks of age, which was accompanied by massive activation of T effector cells in vivo. We also found that the Foxp3+ Tregs in male Foxp3YFP-CreLSL-R111Afl/fl mice were progressively depleted in the periphery. Further analyses showed that the Foxp3+ Tregs expressing the R111A mutant displayed an intrinsic survival defect and that wild-type Foxp3+ Tregs adoptively transferred into young Foxp3YFP-CreLSL-R111Afl/fl mice could rescue the lethal autoimmune phenotype. Mechanistically, we demonstrated that the Regnase-1 readily degraded Bcl2l1 mRNA (encoding Bcl-xL) via binding to the Bcl2l1 mRNA stem loop structure, thus preventing Bcl-xL expression in Tregs. Thus, Tregs expressing the R111A mutant exhibited not only survival defects but also failure to respond to IL-2, resulting in their eventual demise in vivo. Together, our studies suggest that Regnase-1 can have a profound impact on Foxp3+ Tregs and that modulating Regnase-1 in Tregs may have important therapeutic implications.","42381008":"ID: 42381008\nTitle: CTSS regulates macrophage lipid metabolic reprogramming and white matter repair after intracerebral hemorrhage.\nAbstract: Intracerebral hemorrhage (ICH) causes secondary white matter injury, which contributes substantially to long-term neurological disability. Although macrophages accumulate in the perihematomal region and participate in tissue remodeling after ICH, the molecular programs that link macrophage responses to white matter repair remain poorly understood, and no current strategies specifically target macrophage‑mediated white matter restoration. Cathepsin S (CTSS), a lysosomal cysteine protease involved in immune regulation and tissue remodeling, is strongly induced after brain injury; however, its role in post‑ICH white matter pathology has not been defined. A collagenase-induced mouse model of intracerebral hemorrhage (ICH) was established, followed by pharmacological inhibition of Cathepsin S (CTSS) using LY3000328. Single-cell RNA sequencing was performed on perihematomal tissues from Vehicle- and CTSS inhibitor-treated mice to explore CTSS-responsive cell populations and transcriptional programs. Macrophage lipid handling was assessed using flow cytometry, immunofluorescence, and fluorescent myelin debris-based uptake and lipid-transfer assays. A bone marrow-derived macrophage (BMDM)-oligodendrocyte precursor cell (OPC) co-culture system was used to determine whether CTSS inhibition alters macrophage-derived lipid support for OPC differentiation. The LXR agonist GW3965 was applied as a rescue intervention. White matter repair and neurological recovery were evaluated by myelin-associated protein analysis, immunofluorescence, behavioral testing, and transmission electron microscopy. Single-cell analysis identified infiltrating macrophages, particularly adaptive lipid-associated macrophages (aLAMs), as a major CTSS-expressing population after ICH, displaying a transcriptional state related to lipid metabolism and tissue repair. CTSS inhibition attenuated this lipid-associated macrophage program and reduced ApoE, ABCA1, and ABCG1 expression. Mechanistically, CTSS inhibition reduced Npc1/Npc2 expression and disrupted lysosomal cholesterol trafficking, leading to lysosomal cholesterol retention. These changes suggest impaired Npc1/Npc2-associated cholesterol mobilization and attenuation of the LXR-associated macrophage lipid efflux program. In BMDM-OPC co-cultures, CTSS inhibition reduced the transfer of fluorescent macrophage-processed myelin-derived lipids to OPCs and limited OPC differentiation, whereas GW3965 partially restored Npc1/Npc2 expression, macrophage-derived lipid support, and OPC differentiation. Consistently, in vivo CTSS inhibition reduced MBP expression and MBP⁺ axonal wrapping, increased g-ratio values, aggravated myelin ultrastructural abnormalities, and delayed neurological recovery after ICH. CTSS in macrophages supports white matter repair after ICH by maintaining lysosomal cholesterol trafficking and macrophage lipid efflux. CTSS inhibition limits macrophage-derived lipid support for OPCs and impairs remyelination, whereas LXR activation partially restores these reparative responses.","42386968":"ID: 42386968\nTitle: N4-Acetylcytidine enhances synthetic mRNA translation yield and fidelity.\nAbstract: Synthetic mRNA therapeutics offer a versatile platform for treating diverse conditions, including cancer and infectious diseases. For delivery into cells, these mRNAs are encapsulated in lipid nanoparticles and commonly incorporate modified ribonucleotides to improve stability, enhance translation and mitigate immune recognition1. N1-Methylpseudouridine (m1Ψ) has become the industry standard for synthetic mRNAs owing to its effectiveness in promoting translation and reducing immunogenicity2. However, recent studies have shown that m1Ψ can compromise translational fidelity, leading to errors such as premature termination and ribosomal frameshifting3-5. Here we reveal N4-acetylcytidine (ac4C) as a functionally distinct alternative to m1Ψ. Across cultured cell lines, primary human monocyte-derived dendritic cells and mouse liver, ac4C suppressed inflammatory responses as effectively as m1Ψ while driving higher protein yields. Single-molecule imaging of translation revealed broadly similar ribosome densities per mRNA for ac4C-modified and m1Ψ-modified transcripts. However, translation elongation with m1Ψ-modified mRNA was nearly twofold slower than with ac4C, which resulted in reduced protein output and increased ribosome collisions that further limited protein production through the engagement of quality-control pathways and +1 frameshifting. These findings underscore the importance of context in designing therapeutic mRNAs and position the translation elongation rate as a key determinant of the efficacy of modified ribonucleotides.","42387898":"ID: 42387898\nTitle: Adherence to UK Dietary Reference Values and Lower Odds of Non-Alcoholic Fatty Liver Disease: A Secondary Analysis of a Case-Control Study.\nAbstract: The current study aimed to assess the association between the UK dietary reference values (UK-DRV) index and odds of non-alcoholic fatty liver disease (NAFLD). This case-control study enrolled 225 newly diagnosed NAFLD patients and 450 controls, aged 20-60 years. Dietary intake was assessed via a validated food frequency questionnaire, and the UK-DRV index was calculated for all participants. Using multivariable logistic regression, odds ratios (ORs) and 95% confidence intervals (95% CIs) of NAFLD were determined across tertiles of the UK-DRV index. The mean ± SD of the UK-DRV index among control and case groups was 8.84 ± 2.92 and 8.54 ± 2.94, respectively. In the multivariable model, after controlling for potential confounders, the odds of NAFLD were reduced across tertiles of UK-DRV index (OR: 0.39; 95% CI: 0.20-0.74, P for trend: 0.001). Also, each 1-SD increase in UK-DRV index (OR: 0.72; 95% CI: 0.57-0.91, P: 0.007) and its components, including fruits and vegetables (OR: 0.65; 95% CI: 0.50-0.84, P: 0.001) and fibre intake (OR: 0.74; 95% CI: 0.54-0.99, P: 0.048), was inversely associated with odds of NAFLD. Furthermore, each 1-SD increase in sugar intake as a negative component of the UK-DRV index was positively associated with odds of NAFLD (OR: 1.52; 95% CI: 1.22-1.90, p < 0.001). Our findings suggest that a diet with a higher score of the UK-DRV index, characterised by higher intake of fruits, vegetables, and fish and lower intakes of refined carbohydrates, saturated fats, sodium, and simple sugars, may be related to lower odds of NAFLD in adults.","42388975":"ID: 42388975\nTitle: H2S-mediated protein S-sulfhydration: a novel regulatory module in lipid metabolism.\nAbstract: H2S-mediated protein S-sulfhydration is an emerging post-translational modification that regulates key biological processes via regulating enzyme activities, controlling protein-protein interactions, and modulating signal transduction. Lipid metabolism represents an important target of S-sulfhydration-mediated regulation, which fine-tunes lipid metabolic networks including fatty acid turnover, triglyceride metabolism, and cholesterol homeostasis. This review aims to systematically summarize current knowledge on the regulation of lipid metabolism with a focus on S-sulfhydration, and highlight novel molecular targets identified in recent research. By integrating emerging evidence, we demonstrate how S-sulfhydration acts as a regulatory module linking redox signaling and lipid homeostasis, which may be leveraged therapeutically to treat lipid-associated disorders, either using H2S donors or sulfhydrated protein-targeted medications.","42391231":"ID: 42391231\nTitle: Assessment of maternal diet inflammatory status and inflammatory markers in human breast milk.\nAbstract: Human breast milk is a complex bioactive fluid containing multi-functional components that support many infant physiological functions. Maternal diet has been demonstrated to influence human milk components; however, how maternal diet impacts inflammatory markers in human milk remains unclear. This study investigated the association between maternal dietary inflammatory status, assessed using the Dietary Inflammatory Index (DII), and the profile of inflammatory markers in breast milk from healthy lactating women, quantified using cytometric bead array. Dietary intake of lactating mothers (n = 101) was assessed using a 24-hr food recall and categorised using the DII as either pro-inflammatory (score > 0) or anti-inflammatory (score < 0). Thirteen inflammatory markers were quantified in breast milk by flow cytometric bead array (13-plex panel: IL-4, IL-2, IP-10, IL-1β, TNF-α, MCP-1, IL-17A, IL-6, IL-10, IFN-γ, IL-12p70, IL-8, free active TGF-β1). All participant diets were categorised as anti-inflammatory diets (DII score range -4.83 to -1.22). Participants' food intake aligned with dietary guidelines (AUSNUT 2023) for lactating women, with most analysed food parameters classified as anti-inflammatory (19/27). Inflammatory marker analysis revealed a chemokine-dominant profile in breast milk with IP-10, MCP-1 and IL-8 present at the highest concentrations and detected in > 96% of participant human milk samples MCP-1 concentration was weakly associated with DII score (p = 0.025, r2 -0.23, Spearman correlation). This study is the first to investigate the inflammatory index of maternal diets in lactating mothers and characterise inflammatory markers in human milk. Further research is required to fully elucidate the relationship between dietary inflammatory status and inflammatory markers in breast milk and their potential impact on infant health, especially of a more diverse cohort.","42393816":"ID: 42393816\nTitle: The effects of a novel combination of a probiotic supplement (L. rhamnosus GG, L. acidophilus, and L. casei) with a weight gain intervention on body composition, appetite, gut permeability, oxidative stress, and inflammation in underweight adults: study protocol for a double-blind, randomized controlled trial.\nAbstract: Undernutrition, characterized by insufficient energy and protein intake and/or malabsorption, leads to adverse physical and mental health outcomes. Addressing Undernutrition is complex, requiring adequate dietary intake and consideration of the gut microbiota, which is crucial for nutrient absorption and metabolism. Probiotics have shown potential in restoring the gut microbiota balance, enhancing nutrient absorption, and improving growth and immune function. The proposed double-blind, randomized controlled trial (RCT) aims to evaluate the effects of a novel probiotic combination in conjunction with a weight gain intervention on body composition, appetite, gut permeability, oxidative stress, and inflammation in severely underweight adults. A double-blind, randomized controlled trial in which 100 underweight (BMI < 18.5 kg/m2) adults will be recruited and randomly assigned to receive either a probiotic combination (Lactobacillus rhamnosus GG, Lactobacillus acidophilus, and Lactobacillus casei) or an identical placebo alongside a weight gain dietary intervention providing an additional 500 kcal/day for eight weeks will be performed. The primary endpoint will be the difference in body mass index (BMI), calculated as weight/height2 (kg/m2), between the two groups. The secondary endpoints include (1) body composition evaluated by bioelectrical impedance, (2) appetite evaluated via a visual analog scale, (3) gut permeability assessed by the serum zonulin concentration, (4) oxidative stress evaluated by the serum concentration of malondialdehyde (MDA), total antioxidant capacity (TAC), total oxidant status (TOS), glutathione peroxidase (GPx), and inflammation assessed via the C-reactive protein (CRP) level and erythrocyte sedimentation rate (ESR), (5) bowel function assessed via the Bristol stool chart, and (6) dietary intake evaluated via 24-h dietary recall.

While large-scale proteomics improves HF prediction in general populations, its incremental predictive value beyond standard clinical models in MASLD remains unexplored. To identify plasma protein biomarkers for incident HF in MASLD and evaluate the predictive utility of integrating these signatures with the predicting risk of cardiovascular disease events (PREVENT) clinical model. We prospectively analyzed 17,091 individuals with MASLD at baseline. Multivariable and LASSO-Cox regressions were applied to 2911 plasma proteins to identify optimal predictors. Predictive discrimination and reclassification were assessed using Harrell's C-index, time-dependent area under the curve (AUC), net reclassification improvement (NRI), integrated discrimination improvement (IDI), and decision curve analysis (DCA). Over a median follow-up of 13.56 years, 953 incident HF events occurred. Integrating the PREVENT model with a 37-protein panel substantially improved predictive discrimination (C-index 0.805 vs. 0.723; ΔC-index 0.082, 95%CI: 0.064-0.100). Moreover, a parsimonious model containing only 5 proteins (NT-proBNP, WFDC2, LTBP2, BCAN, HAVCR1) delivered a meaningful incremental improvement over the PREVENT baseline (C-index 0.769 vs. 0.723; ΔC-index 0.046, 95%CI: 0.027-0.064). Pathway analyses indicated these proteins associating with systemic inflammation and extracellular matrix remodeling. Large-scale proteomics significantly enhances HF risk prediction in MASLD, providing a robust tool for identifying high-risk individuals who may benefit from intensive clinical monitoring and preventive strategies.","42396914":"ID: 42396914\nTitle: Folate and global health review series, part 4: syntheses on folate and autoimmune diseases and skeletal outcomes.\nAbstract: Autoimmune diseases and bone density loss (osteopenia and osteoporosis) are chronic conditions of complex aetiology that affect diverse populations. Folate may be associated with a higher risk of these disorders due to its essential role in one-carbon metabolism required for nucleotide synthesis, homocysteine metabolism, and methylation processes. However, the evidence on this association is inconclusive. We searched MEDLINE, Embase, CINAHL, the Cochrane Library, and the Database of Abstracts of Reviews of Effects from inception to February 2024 for systematic reviews and meta-analyses investigating the associations between folate exposure (dietary intake, supplementation, or blood concentrations) and any autoimmune diseases or skeletal outcomes. Pairs of researchers screened the retrieved syntheses, extracted the relevant data, assessed their risk of bias using the ROBIS tool, and evaluated the credibility of the evidence using predefined criteria. We found 19 reviews reporting 25 unique associations: 15 on autoimmune diseases (multiple sclerosis, inflammatory bowel disease, psoriasis, human immunodeficiency virus, vitiligo, and systemic lupus erythematosus) and 10 on skeletal outcomes (fractures and bone mineral density loss). Most of the syntheses consisted of small-scale case-control studies. The risk of bias in the included syntheses was high. Owing to the small sample sizes, all the unique associations were assessed to be at a weak level of credibility. The evidence on the relationship between folate status and autoimmune diseases or skeletal outcomes was limited in breadth and depth. Most of the 25 unique associations were reported by a single synthesis comprising small-scale studies. Subgroup analyses or dose-response analyses were severely limited or unavailable. More well-powered, prospective studies investigating the relationships between folate and autoimmune and skeletal conditions are warranted.

The microbial species within a microbiome, on the one hand, compete for resources, while on the other hand, they exchange vital metabolites to support their survival. These interactions are influenced by the microbial genetic repertoire, environmental conditions, and availability of nutrients. We developed EcoGS (http://www.github.com/KaletaLab/EcoGS), a metabolic modeling tool designed to predict the ecological interactions between pairs of microbes. Applying EcoGS to the microbiomes of two distinct human cohorts revealed a shift from collaborative to exploitative ecological interactions associated with increased dietary intake of simple sugars (glucose and fructose) in diabetic individuals and those living industrialized lifestyles. On the other hand, the consumption of cobalamin (vitamin B12), phylloquinone (vitamin K1), and biotin (vitamin B7), among other compounds, was associated with increased collaboration in the gut microbiome. We conclude that the abundance of simple sugars as an energy source reduces the necessity for microbes to cooperate, thereby increasing competition and hostility among microbiome members. Moreover, our study proposes multiple compounds, such as urate, deoxyadenosine, deoxyguanosine, and hypoxanthine, for in vitro validation tests as dietary interventions that have the potential to restore the ecological balance within the community.

Active-comparator, new-user target trial emulation using electronic medical records from 36 hospitals across China from 2014 to 2023, with follow-up through 1 October 2025. Eligible adults had histologically confirmed HCC and T2D, underwent R0 resection and initiated a GLP-1RA or DPP-4i within postoperative days 0 to 90. Time zero was the first qualifying prescription or order date. The primary estimand was intention-to-treat; a prespecified per-protocol analysis assessed sustained adherence. The primary outcome was recurrence-free survival (RFS), treating death without recurrence as a competing event; overall survival (OS) was secondary. The study was registered with the Chinese Clinical Trial Registry (ChiCTR2600118495). Among 42 855 patients with HCC and T2D who underwent liver resection, 1249 were included in the final analytical cohort, including 723 DPP-4i initiators and 526 GLP-1RA initiators; median follow-up was 50.8 months. In weighted intention-to-treat analyses, GLP-1RA versus DPP-4i initiation was associated with longer RFS (cause-specific HR 0.80, 95% CI 0.67 to 0.96; p=0.016) and OS (HR 0.58, 95% CI 0.47 to 0.71; p<0.001). Per-protocol analyses were directionally consistent. Postoperative GLP-1RA initiation, compared with DPP-4i initiation, was associated with delayed recurrence and longer OS; prospective confirmation is warranted.

A total of 36 gilts and 36 barrows at 110 days of age were allocated to six groups in a 3 × 2 factorial arrangement consisting of three dietary protein levels and two sexes. Dietary crude protein levels were 17%, 15%, and 13% during phase I, and 15%, 13%, and 11% during phase II. The whole feeding trial lasted 51 days. Overall, lowering dietary protein levels altered the digestibilities of crude protein, ether extract, calcium and phosphorus (P < 0.01), and exerted sex-specific influences on serum total protein and nitric oxide concentrations (P < 0.05). Among gut microbiota, five genera responded to protein restriction (P < 0.05), eight showed sex differences (P < 0.05), and six exhibited sex-specific responses to dietary protein levels (P < 0.05). Dietary protein restriction reduced gut microbiota-derived ammonia nitrogen and six of eight biogenic amines (P < 0.05); four of these metabolites differed between sexes (P < 0.05), and four showed protein × sex interactions (P < 0.05). The nitrogen-related metabolites were positively correlated with specific microbiota only in gilts (P < 0.05). In conclusion, dietary protein restriction induced sex-specific alterations in gut microbiota and nitrogen-associated metabolites in finishing pigs, and such metabolic responses were exclusively linked to microbiota changes in gilts but not in barrows.","42400345":"ID: 42400345\nTitle: Nephronophthisis: Current clinical spectrum and molecular pathogenesis.\nAbstract: Nephronophthisis (NPH) is a ciliopathy primarily affecting renal tubules and interstitial tissue, ultimately progressing to end-stage kidney disease (ESKD). The clinical spectrum of NPH is broad and can be classified according to the age at onset into infantile, juvenile, adolescent, and late-onset forms. Histopathologically, NPH is characterized by corticomedullary cysts, tubular atrophy, interstitial fibrosis, and cystic dilatation of distal tubules. The kidneys may appear normal in early stages but gradually shrink with disease progression. More than 20 causative genes have been identified, with NPHP1 being the most common. These genes encode proteins that localize predominantly to the ciliary transition zone and basal body, where they regulate ciliary structure and signaling. Loss of ciliary function disrupts epithelial polarity, intracellular trafficking, and signal transduction, leading to tubular injury and fibrosis. When extrarenal organs such as the retina, liver, or central nervous system are affected, the condition is defined as nephronophthisis-related ciliopathies (NPH-RC). This review summarizes the current understanding of NPH classification, clinical features, and molecular mechanisms. Here, we highlighted recent advances in genetic discoveries, pathogenic signaling pathways, and therapeutic strategies, including gene therapy and targeted molecular interventions.","42401371":"ID: 42401371\nTitle: Association between dietary inflammatory index and obesity and dietary intake in Japanese adults with type 2 diabetes: A cross-sectional study (JDDM 86).\nAbstract: To assess the associations between the Dietary Inflammatory Index (DII) and obesity and dietary intake in adults with type 2 diabetes (T2DM), and to compare the findings with those obtained using the modified Japanese Diet Index (mJDI). We conducted a cross-sectional study of 1565 adults with T2DM in Japan between 2014 and 2019. Dietary intake was assessed using a validated food frequency questionnaire. The DII calculation was based on 25 nutrients. Participants were categorized into DII tertiles, and obesity was defined as BMI ≥25 kg/m2. Logistic regression models were used to estimate associations between the DII and obesity with sequential adjustment for demographic, dietary, and lifestyle factors. Subgroup and sensitivity analyses were performed, and correlations between the DII and food group intakes were examined. Participants in higher DII tertiles were younger, more often male, and had higher BMI, lower energy intake, lower protein intake per kg of body weight, and lower physical activity. Higher DII scores were associated with greater odds of obesity (OR 2.412, 95% CI 1.751-3.323; P trend <0.001). The association was consistent across sex, age, energy intake, and physical activity categories. The DII was inversely correlated with intakes of vegetables, fruits, fish/seafood, soy products, and other nutrient-dense foods. Sensitivity analyses using BMI ≥30 kg/m2 showed similar but weaker associations. Higher DII scores were associated with obesity and lower intake of nutrient-dense foods in Japanese adults with T2DM, whereas higher mJDI scores were inversely associated with obesity. Associations appeared stronger for the DII.","42401471":"ID: 42401471\nTitle: Precise diagnosis of hepatocellular carcinoma and acute kidney injury through near-infrared imaging utilizing a fluorescence probe for monitoring α-l-fucosidase.\nAbstract: Herein, hepatocellular carcinoma (HCC) and acute kidney injury (AKI) were accomplished using α-l-fucosidase (AFU)-responsive fluorescent probe, HD-AFU, which incorporates the canonical AFU recognition moiety and a structurally optimized hemicyanine-thioxanthene signaling unit. In comparison with recently reported probes, HD-AFU demonstrated robust and reliable performance in monitoring AFU activity across HCC and AKI models. This probe enabled mitochondrial-targeted intracellular imaging to track AFU dynamics during progression and therapeutic intervention. In the orthotopic transplanted tumor mouse model, HD-AFU exhibited consistent capabilities for visualizing HCC status. To validate the accuracy of the probe in detecting AFU in AKI, we established four AKI models, including cisplatin-induced, gentamicin-induced, hyperuricemic nephropathy, and diabetic nephropathy models. The accurate establishment of these four models holds significant importance for subsequent fluorescence imaging studies. Additionally, we employed losartan and metformin to treat hyperuricemic nephropathy and diabetic nephropathy, respectively, and utilized the probe to achieve the screening and validation of therapeutic drugs. Furthermore, in a long-term induced HCC and AKI model validated by serum indices and histopathological assessment, HD-AFU successfully visualized the diagnostic and therapy process. These presented herein offer valuable insights for the development of effective diagnostic strategies.","42403423":"ID: 42403423\nTitle: B vitamins intake and cancer risk: a structured narrative review of evidence on riboflavin, pyridoxine, cobalamin and folate.\nAbstract: B vitamins play key roles in one-carbon metabolism, DNA synthesis and methylation, and redox regulation. Their potential association with cancer risk remains debated due to heterogeneous findings and methodological limitations across studies. This structured narrative review aimed to summarize and clinically contextualize the available evidence on the relationship between the intake of vitamins B2 (riboflavin), B6 (pyridoxine), B12 (cobalamin) and folate (vitamin B9) and the risk of selected cancers. A structured literature search was performed in PubMed up to 2 September 2025. Evidence was synthesized narratively, prioritizing meta-analyses (including dose-response meta-analyses) of observational studies, and including randomized controlled trials on B-vitamin supplementation when clinically relevant. Methodological quality and risk of bias were appraised narratively focusing on key domains such as exposure assessment, confounding, selection bias, and outcome assessment. Most evidence derives from observational studies assessing dietary intake and circulating biomarkers. Riboflavin and vitamin B6 intake were generally associated with a reduced risk of colorectal cancer in several meta-analyses, including dose-response analyses. Vitamin B12 showed inconsistent associations across cancer sites, with concerns regarding confounding by diet and baseline nutritional status. Folate intake and folic acid supplementation showed mixed findings, with some evidence suggesting protective effects in specific populations, while randomized trials raised concerns about potential adverse effects in selected contexts and dosages. Overall, heterogeneity across studies was substantial, partly explained by differences in exposure definitions, baseline folate fortification policies, and co-interventions. Available evidence suggests potentially protective associations for riboflavin and vitamin B6-particularly for colorectal cancer-whereas findings for vitamin B12 and folate remain inconsistent and context-dependent. Given relevant methodological limitations and potential biases, further well-designed prospective studies and targeted trials are needed to clarify dose, timing and population-specific effects of B vitamins on cancer risk.","42404803":"ID: 42404803\nTitle: Association between dietary intake of fatty acids, central obesity, and OAB: insights from a prospective cohort for weight management and dietary prevention.\nAbstract: Overactive bladder (OAB) is a common condition that affects both men and women, but its relationship with central obesity and the dietary intake has not been adequately elucidated. Our study aims to investigate associations between central obesity replacement indices, dietary intake of sugar and lipids, and OAB risk using National Health and Nutrition Examination Survey 2005-2016 data. Cross-sectional study. This study analyzed 24,675 adults (4848 OAB cases). Weight, body mass index, and other central obesity replacement indices (waist circumference, weight-adjusted waist index, waist-to-height ratio (WHtR), body roundness index (BRI)) and dietary nutrients intake (carbohydrate, sugars, fat, saturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids (PUFAs), and cholesterol) were assessed. Propensity score matching (1:2) balanced covariates. Multivariable logistic regression and generalized additive models evaluated dose-response relationships. All central obesity indices showed significant positive associations with OAB (p < 0.001), with WHtR and BRI demonstrating the strongest effects (adjusted odds ratio (OR) = 2.04, 95% confidence interval: 1.80-2.30). Nonlinear relationships were observed, particularly for WHtR (degrees of freedom = 3.30-6.16). Dietary analysis revealed that OAB patients had significantly higher consumption of total energy, carbohydrates, and sugars (all p < 0.05), and higher sugar intake increased OAB risk (OR = 1.32, p = 0.0016), while PUFAs were protective (OR = 0.79, p = 0.0159). Central obesity replacement indices, especially WHtR and BRI, strongly predict OAB risk. Dietary modifications, including reducing sugars and increasing PUFAs intake, may complement abdominal fat reduction for OAB prevention. These findings highlight the importance of combined weight management and dietary modifications for OAB prevention in high-risk populations. Can the fats we eat and belly fat affect bladder health? Overactive bladder (OAB) can seriously affect daily life. Using data from over 24,000 U.S. adults, this study found that people with more belly fat were more likely to have OAB, especially when their waist-to-height ratio and body roundness index were high. Diet also mattered—those who ate more sugars had higher OAB risk, while consuming more healthy fats, such as polyunsaturated fatty acids (PUFAs), was linked to lower risk. Managing abdominal fat and improving diet may help prevent or relieve OAB symptoms.","42405665":"ID: 42405665\nTitle: [Nutritional monitoring in peritoneal dialysis: Biological and non-biological markers and dietary strategies].\nAbstract: To provide a practical overview of methods for assessing and monitoring nutritional status in patients undergoing PD, as well as the main dietary strategies aimed at preventing or correcting malnutrition. A literature search was conducted in the PubMed and Embase databases for publications published between 2000 and 2025. The search included the following keywords: peritoneal dialysis, nutrition, protein-energy wasting, nPNA, dietary management, and nutritional assessment. International guidelines from the Kidney Disease Outcomes Quality Initiative (KDOQI), the International Society of Renal Nutrition and Metabolism (ISRNM), and the French National Authority for Health (HAS), together with observational studies, clinical trials, and relevant reviews on nutritional monitoring in PD, were analyzed. Nutritional assessment in PD relies on a multidimensional approach combining biological markers (albumin and prealbumin, interpreted in the context of inflammation); composite indices including the malnutrition-inflammation score (MIS), prognostic nutritional index (PNI), and subjective global assessment (SGA); evaluation of dietary intake; and functional tools such as handgrip strength and bioimpedance analysis. Calculation of normalized protein nitrogen appearance (nPNA) provides a useful indicator of protein intake and helps guide nutritional prescriptions. Current recommendations advocate a protein intake of approximately 1.2-1.3 g/kg/day, adjusted for dialysis-related protein losses and inflammatory status. Glucose absorption from the dialysate should also be taken into account when estimating energy intake. Management of sodium, phosphorus, potassium, and calcium intake is essential to limit metabolic and cardiovascular complications. Balanced dietary patterns, such as an adapted Mediterranean diet or well-designed plant-based approaches, may contribute to improving nutritional status. Nutritional management of patients undergoing PD requires regular multidisciplinary assessment combining biological, clinical, and dietary indicators. An individualized approach that accounts for dialysis-related losses and patient-specific characteristics is essential to prevent malnutrition and improve long-term outcome. La dénutrition protéino-énergétique est fréquente chez les patients en dialyse péritonéale (DP) et constitue un déterminant majeur de morbi-mortalité. La surveillance nutritionnelle représente donc un élément central de la prise en charge de ces patients. Toutefois, l’évaluation du statut nutritionnel en DP est complexe et nécessite l’intégration de marqueurs biologiques, d’outils cliniques et d’évaluations alimentaires. Proposer une synthèse pratique des méthodes d’évaluation et de suivi du statut nutritionnel chez les patients en DP, ainsi que des principales stratégies diététiques visant à prévenir ou corriger la dénutrition. Une recherche bibliographique a été réalisée dans les bases de données PubMed et Embase pour les publications entre 2000 et 2025. Les mots clés utilisés incluaient notamment peritoneal dialysis, nutrition, protein-energy wasting, nPNA, dietary management et nutritional assessment. Les recommandations internationales (Kidney Disease Outcomes Quality Initiative [KDOQI], International Society of Renal Nutrition and Metabolism [ISRNM], Haute Autorité de santé [HAS]) ainsi que les études observationnelles, essais cliniques et revues pertinentes portant sur la surveillance nutritionnelle en DP ont été analysés. L’évaluation nutritionnelle en DP repose sur une approche multidimensionnelle associant marqueurs biologiques (albumine, pré-albumine interprétées dans un contexte inflammatoire), indices composites (Malnutrition Inflammation Score [MIS], indice nutritionnel pronostique [PNI], Subjective Global Assessment [SGA]), estimation des apports alimentaires et outils fonctionnels tels que la force de préhension ou la bioimpédancemétrie. Le calcul du Normalized Protein Nitrogen Appearance (nPNA) constitue un indicateur utile des apports protéiques, permettant d’adapter les prescriptions nutritionnelles. Les recommandations actuelles préconisent un apport protéique d’environ 1,2 à 1,3 g/kg/j, ajusté aux pertes protidiques liées à la dialyse et à l’état inflammatoire. L’absorption de glucose via le dialysat doit être intégrée dans le calcul des apports énergétiques. La gestion des apports en sodium, phosphore, potassium et calcium est également essentielle afin de limiter les complications métaboliques et cardiovasculaires. Des modèles alimentaires équilibrés, tels que le régime méditerranéen adapté ou certaines approches végétales bien conduites, peuvent contribuer à améliorer le statut nutritionnel. La prise en charge nutritionnelle des patients en DP nécessite une évaluation régulière et multidisciplinaire combinant indicateurs biologiques, cliniques et diététiques. Une approche individualisée, intégrant les pertes liées à la technique et les caractéristiques du patient, est essentielle pour prévenir la dénutrition et améliorer le pronostic à long terme. Ce travail s’inscrit dans la continuité des initiatives de la commission Dialyse de la Société francophone de néphrologie, dialyse et transplantation (SFNDT), engagée dans l’élaboration de référentiels destinés à harmoniser les pratiques et à renforcer la qualité des soins en dialyse. Après le premier référentiel national consacré à la biologie en hémodialyse, cette revue propose un cadre de référence pour la surveillance nutritionnelle en dialyse péritonéale, en intégrant les données récentes de la littérature et les approches innovantes, notamment celles issues de l’intelligence artificielle. Elle participe ainsi à la structuration d’une démarche commune de suivi nutritionnel, personnalisée, fondée sur les preuves et partagée entre les équipes de néphrologie et de diététique.","42406127":"ID: 42406127\nTitle: A non-enzymatic sensor based on rGO/Pt NPs/Fc-Tyr/POPD nanocomposite for hydrogen peroxide determination in liver cancer tissues.\nAbstract: Malignant tumors remain a major global health challenge, highlighting the need for rapid and sensitive analytical tools for investigating cancer-associated oxidative stress. In this study, we developed a non-enzymatic electrochemical hydrogen peroxide (H₂O₂) sensor based on a reduced graphene oxide/platinum nanoparticle/ferrocene-tyramine/poly(o-phenylenediamine) (rGO/Pt NPs/Fc-Tyr/POPD) nanocomposite. H₂O₂, although not a tumor-specific biomarker, is an important reactive oxygen species associated with oxidative stress in cancer-related systems. The proposed sensing platform integrates the high conductivity of rGO, the electrocatalytic activity of Pt NPs, the TSA-derived Fc-Tyr deposition strategy, and the anti-interference properties of POPD. The sensor exhibited two wide linear detection ranges (5.0 µM-570 µM and 570 µM-10.5 mM), a low detection limit of 1.18 µM, and a rapid response time of less than 5 s. In addition, the sensor demonstrated satisfactory selectivity, reproducibility, and stability. Compared to previously reported rGO/Pt-based H₂O₂ sensors, the present platform introduces a TSA-derived Fc-Tyr deposition strategy to facilitate interfacial electron transfer and increase the density of redox-active species. The sensor was successfully applied to monitoring H₂O₂ changes in cultured cancer cells and ex vivo tumor tissue-derived samples under chemically stimulated oxidative conditions. These findings suggest that the proposed system may provide a useful tool for investigating oxidative-stress-associated biological processes and electrochemical H₂O₂ determination.","42409273":"ID: 42409273\nTitle: Molecular cloning and functional characterization of tyrosine decarboxylase genes from galanthamine-producing Narcissus pseudonarcissus 'King Alfred.'.\nAbstract: Tyrosine decarboxylases (TyDCs) are pyridoxal 5'-phosphate-dependent enzymes that catalyze the conversion of l-tyrosine into tyramine, a key entry point for Amaryllidaceae alkaloid biosynthesis. From transcriptome data of Narcissus pseudonarcissus 'King Alfred', two full-length TyDC isoforms, NpTyDC1 and NpTyDC2, were identified. In this study, both genes were cloned, heterologously expressed in Escherichia coli, and purified for functional characterization. Fluorescent protein tagging indicated nucleocytoplasmic localization of both isoforms. Enzymatic assays coupled with HPLC-MS/MS demonstrated that NpTyDC1 exhibits decarboxylase activity with a strong preference for l-tyrosine, producing tyramine as the predominant product. In contrast, NpTYDC2 showed no detectable tyrosine decarboxylase activity under the conditions tested, and no tryptophan decarboxylation despite structural features associated with indole decarboxylases but displayed minor activity toward l-phenylalanine. Collectively, these findings establish NpTyDC1 as a strong candidate for directing tyrosine into the Amaryllidaceae alkaloid biosynthesis. By integrating computational predictions with biochemical validation, this study provides new insight into the TyDC functional diversity in Narcissus.","42409346":"ID: 42409346\nTitle: Astragalin from Morus alba L. ameliorates high-fat diet-induced obesity-related metabolic disturbances in mice and is associated with hepatic AMPK/PI3K/AKT signaling.\nAbstract: Morus alba L. (M. alba) also known as white mulberry is recognized in traditional Chinese medicine (TCM) and Ayurveda as a functional food and nutraceutical supplement for treating conditions such as hypertension, diabetes, and obesity. In TCM, mulberry leaves are specifically described as enhancing hepatic lipid metabolism, promoting lipid excretion to support obesity treatment. This study aimed to investigate the anti-obesity potential of M. alba leaf extract and its flavonoid component, astragalin (ASG), using a high-fat diet (HFD)-induced obese mouse model, and to elucidate the underlying molecular mechanisms. HFD-fed mice were treated with M. alba aqueous extract or ASG using a curative treatment approach. Body weight, glucose tolerance, insulin sensitivity, serum lipid profiles, hepatic steatosis, and inflammatory cytokines were assessed. Systemic and hepatic inflammation was measured by enzyme-linked immunosorbent assay (ELISA), while glucose transporter (GLUT1 and GLUT2) transcripts and protein levels were measured by RT-PCR and Western blotting, respectively. Molecular interactions were evaluated using cellular thermal shift assay (CETSA), drug affinity responsive target stability (DARTS), and molecular docking analyses, while AMP-activated protein kinase (AMPK), phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT), calcium/calmodulin-dependent protein kinase kinase 2 (CaMKK2) and liver kinase B1 (LKB1) phosphorylation was also assessed by Western blotting. Pharmacologic inhibition with Compound C was performed to confirm AMPK involvement. Treatment with M. alba extract significantly reduced body weight gain, improved serum lipid profiles, and attenuated hepatic lipid accumulation in obese mice. Phytochemical analysis identified ASG as a major bioactive constituent. ASG recapitulated several beneficial effects of the extract, including improvements in body weight gain, glucose tolerance, insulin sensitivity, hepatic lipid burden, and inflammatory status. ASG reduced systemic and hepatic levels of pro-inflammatory cytokines and modulated hepatic and intestinal GLUT1/2 transcripts and protein levels. Mechanistically, ASG showed evidence of AMPK engagement in CETSA, DARTS, and docking analyses, and was associated with increased hepatic AMPK and PI3K/AKT phosphorylation. Co-administration of Compound C attenuated several metabolic benefits of ASG, supporting AMPK involvement. ASG ameliorates obesity-related metabolic abnormalities in HFD-fed mice and is associated with AMPK engagement and increased hepatic AMPK/PI3K/AKT phosphorylation. These findings support ASG as a promising natural lead compound for obesity-related metabolic dysfunction, although further studies are needed to define its direct target interaction and downstream signaling more conclusively.","42410764":"ID: 42410764\nTitle: Association between hemoglobin glycation index and new-onset diabetes mellitus in individuals with chronic liver disease: Findings from a prospective cohort study using CHARLS data.\nAbstract: The hemoglobin glycation index (HGI), which measures the difference between observed and predicted glycated hemoglobin, is strongly associated with diabetic complications. However, its relationship with new-onset diabetes in patients with chronic liver disease (CLD) remains unexplored. This study aimed to investigate this association using data from the China Health and Retirement Longitudinal Study database. This study included 329 participants aged ≥45 years with CLD from the China Health and Retirement Longitudinal Study database. HGI was calculated as glycated hemoglobin - (0.013 × fasting plasma glucose + 4.804). Based on baseline HGI levels, participants were categorized into 3 groups (Q1-Q3). The primary endpoint was the occurrence of new-onset diabetes mellitus events. The Kaplan-Meier curves, multivariable Cox proportional hazards models, and restricted cubic spline analysis were applied to explore the association between baseline HGI levels and the risk of diabetes mellitus incidence among individuals with CLD. In the adjusted multivariable Cox regression analysis, HGI was significantly associated with a 53% increased risk of diabetes (hazard ratio = 1.53, 95% confidence interval: 1.17-1.99, P = .002). The Kaplan-Meier curve analysis revealed a significant difference in the occurrence of diabetes mellitus among the HGI groups. Significant risk thresholds were identified at HGI = -0.94, beyond which diabetes mellitus risk increased substantially. Stratified and interaction analyses confirmed the stability of this association. An increase in baseline HGI levels was significantly associated with the risk of diabetes mellitus in individuals with CLD. HGI can be used as a potential indicator for predicting the long-term risk of diabetes incidence in such patients.","42411358":"ID: 42411358\nTitle: Lipidomic and Transcriptomic Insights into Hepatic Lipid Remodeling Induced by Peony Seed Oil.\nAbstract: Peony seed oil (PSO), rich in unsaturated fatty acids, especially α-linolenic acid, may influence hepatic lipid metabolism, but its mechanisms remain unclear. We evaluated the effects of PSO in high-fat diet-fed rats using biochemical assays, liver histology, hepatic lipidomics, transcriptomics, and targeted validation. PSO improved serum lipid profiles, reduced hepatic cholesterol and triglyceride levels, and alleviated steatosis. Lipidomics revealed extensive remodeling of hepatic lipid subclasses, with differential lipids enriched in polyunsaturated fatty acid (PUFA)-containing species. Integrated multiomics analysis showed coordinated changes in PUFA-containing phospholipids and fatty acid metabolism-related transcripts, including Fads1, Fads2, Ppara, Elovl5, and Cpt1a. Cross-omics correlations suggested adaptive regulation of endogenous PUFA metabolism rather than simple dietary lipid incorporation. Validation confirmed increased hepatic expression of Fads1, Fads2, and Ppara. These findings indicate that PSO improves hepatic lipid homeostasis by coordinating lipid composition and metabolic regulatory pathways.","42413844":"ID: 42413844\nTitle: Protocatechuic acid promotes c-Myc-mediated cell proliferation by directly targeting TRAF2.\nAbstract: Protocatechuic acid (PCA) is both a prominent gut microbiota-derived metabolite of anthocyanins and a naturally occurring phenolic acid presents in various edible plants. Although this compound has been reported to exert cytotoxic effects at millimolar concentrations in vitro, its plasma levels following dietary intake are limited to the non-toxic nano-to micromolar range. Here, we identify the adaptor protein TNF Receptor Associated Factor 2 (TRAF2) as a direct molecular target of this phenolic compound. By computational modeling and biophysical assays, including fluorescence spectroscopy and calorimetry, we demonstrate that PCA directly binds the TRAF domain of TRAF2, leading to decreased thermal stability and potential alteration of trimeric interfaces. By performing functional analyses in HAP1 leukemia cells, we provide evidence that PCA, at low micromolar concentrations, increases cell viability through a TRAF2-dependent mechanism. Mechanistically, PCA binding to TRAF2 inhibits JNK signaling while redirecting TRAF2 toward pro-survival signaling routes involving c-Myc. Collectively, these findings uncover TRAF2 as a novel molecular target of PCA and provide a mechanistic basis for its effects on cell viability.","42415049":"ID: 42415049\nTitle: Association of habitual diet and bone marrow adipose tissue - magnetic resonance imaging in a population-based sample.\nAbstract: Bone marrow adipose tissue (BMAT) is a metabolically active fat depot that may influence bone and hematopoietic function, yet its relationship with habitual diet remains largely unexplored at the population level. As diet represents an easily modifiable factor, a better understanding of its role in bone health and potential sex-specific differences is needed. We examined how habitual intake of energy-providing nutrients (fat, carbohydrates, protein, alcohol) and micronutrients (calcium, phosphorus, vitamin D) relates to imaging-derived measures of BMAT. In a sample from a population-based cohort, habitual diet was assessed based on a food frequency questionnaire and repeated 24 h recalls. Using magnetic resonance imaging (MRI) with a 2-point T1-weighted Dixon sequence, fat fraction of BMAT was quantified at vertebrae L1 and L2 in N = 297 participants (44% women, mean age 56.1 years, mean BMI 28.0 kg/m²) and at left and right femur in N = 163 participants (67% women, mean age 57.5 years, mean BMI 27.1 kg/m²) with available dietary data. Associations between habitual diet and BMAT were assessed using correlation analyses and linear regression models in the overall study population and stratified by sex, adjusting for age, BMI, physical activity, and diabetes status. Mean vertebral and femoral BMAT were 54.8% and 86.5% in women, and 54.6% and 89.8% in men, respectively. Vertebral and femoral BMAT were positively correlated in women (ρ = 0.54, p < 0.001) and men (ρ = 0.36, p = 0.0096). Associations between habitual intake of energy-providing nutrients or micronutrients and BMAT were mostly non-significant across anatomical sites and sexes. Only in women, protein intake was positively associated with vertebral BMAT (β = 1.03, 95%CI [0.2, 1.9], p = 0.020, per percent of total energy intake). In men, an opposite effect direction was observed, which was not significant (β =-0.73, 95%CI [-1.6, 0.1], p = 0.096). For femoral BMAT, all associations were non-significant in either sex. In this population-based sample, habitual dietary intake of energy-providing nutrients and micronutrients showed no consistently significant association with vertebral or femoral BMAT in women and men. Opposite effect directions in men and women, as well as one significant association between protein intake and vertebral BMAT in women were observed in exploratory analyses. This may indicate potential site- and sex-specific differences, underlining the distinct biological properties of this adipose tissue depot.","42418776":"ID: 42418776\nTitle: Nutrition Therapy in Critically Ill Adults.\nAbstract: In the acute phase of critical illness, adults have severe catabolism, inflammation, muscle loss, and gut dysfunction, all of which shape nutritional requirements. Early enteral nutrition supports gut integrity and microbiome health, but trials have shown that early short-term parenteral nutrition is a safe alternative when enteral feeding is not possible. Large trials have shown that early full-dose energy delivery offers no benefit over restrictive dosing and may increase gastrointestinal and metabolic complications, findings that support a restrictive nutrition strategy, especially in patients who have circulatory shock or are at risk for refeeding syndrome. Similarly, large trials have shown no advantage of high-dose over standard-dose protein and suggest harm in patients with acute kidney injury. Because adverse events are common with enteral nutrition, safe nutrition delivery requires gradual advancement, strategies for prevention of refeeding syndrome, glycemic control, and avoidance of routine gastric residual volume monitoring. Patient heterogeneity underscores the need for precise, biomarker-guided, phase-specific nutrition to preserve lean muscle mass and improve recovery.","42418876":"ID: 42418876\nTitle: Deciphering underground decarboxylase activity towards Nε-modified lysine derivatives in enterobacteria.\nAbstract: Thermal food processing generates diverse compounds interacting with the gut microbiota. Despite their abundance, the microbial turnover of diet-borne Nε-modified lysine derivatives remains largely unexplored. We demonstrate that the enterobacterial ornithine decarboxylase SpeC degrades the prevalent advanced glycation end product Nε-carboxymethyllysine (CML) to carboxymethylcadaverine via an underground activity (∼4 molecules/enzyme/min). This promiscuity extends to additional Nε-modified lysine derivatives - namely formylated (FmL), monomethylated (MML) and dimethylated (DML) lysine - yielding previously unknown biogenic amines (mono- and dimethylcadaverine, formylcadaverine). Functionally, SpeC enables Escherichia coli to utilize CML as a sole nitrogen source. In specific strains, this metabolism reinforces pH-stress responses, supporting survival under mild acidic conditions typical for the colon. Furthermore, SpeC orthologs are widespread across human gut genomes, correlating with geography, diet, and disease. Together, these findings suggest a potential diet-microbiome communication axis, linking the intake of modified dietary chemicals to microbial physiology and hypothesized host impacts.","42419161":"ID: 42419161\nTitle: Dietary patterns and Alzheimer's disease: East-west perspectives and future intervention strategies.\nAbstract: Among various modifiable risk factors, dietary patterns (DPs), as a holistic lifestyle intervention, have become a focus of current research due to their protective effects on cognitive health. Classic Western DPs, such as the Mediterranean diet (MedDiet), have been widely confirmed to effectively improve cognitive function, thereby reducing the risk of Alzheimer's disease (AD). However, existing evidence mainly concentrates on Western populations and their DPs, including the MODERN (Machine learning-assisted Optimizing Dietary intERvention against demeNtia risk) diet optimized using machine learning. Given the significant differences in food types, dietary habits, and cooking methods among Asian populations, research on localized DPs optimized for cognitive health in Asian populations remains insufficient. In this context, the team at the Department of Geriatrics, Shanghai Sixth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine has taken the lead in systematically defining the Shanghai Cognitive Diet Pattern (SCDP). This review aims to comprehensively outline the core features and potential biological mechanisms relevant to AD in both classic Western DPs and the emerging East Asian DP. Subsequently, this review will systematically compare Eastern and Western DPs. In conclusion, this review proposes shifting​ dietary strategies from population-level adaptation to individual precision, in conjunction with multimodal lifestyle management, and offers novel strategies for the prevention and management of AD.","42419343":"ID: 42419343\nTitle: Nutritional, functional, and psychological considerations for incretin-based therapies in adults-an EASO, EFAD, and ECPO Consensus Statement.\nAbstract: Incretin-based therapies, including GLP-1 receptor agonists and dual GLP-1-GIP receptor agonists, have transformed obesity management, producing substantial weight loss and cardiometabolic benefits, with potential improvements in obesity-related complications, physical function, quality of life, and psychological wellbeing for many individuals. However, reduced appetite, rapid weight loss, gastrointestinal adverse effects, and changes in eating behaviour might create nutritional, functional, or psychological risks in some individuals. This EASO-EFAD-ECPO Consensus Statement outlines pragmatic nutritional, functional, and psychological considerations during incretin-based therapy treatment. We synthesise evidence on medical nutrition therapy, including protein targets during weight loss, dietary quality, and mitigation of gastrointestinal adverse events. We discuss pragmatic approaches that could help support preservation of fat-free mass and physical function during weight loss, including adequate protein intake and progressive resistance exercise. We emphasise the psychological and identity-related challenges during incretin-based therapy, including shifts in food reward, coping, and social connection, and recommend psychological screening, with integrated support where needed. We propose pragmatic monitoring during weight loss, including diet quality, micronutrient risk, and functional measures, with body-composition assessment where indicated. We suggest approaches to address disparities in access and adherence to ensure equity. We discuss the importance of shared decision making with the patient in decisions to start, up-titrate, delay, pause, down-titrate, or discontinue incretin-based therapies, considering the physical and psychological risks of treating versus not treating. Finally, we identify future research priorities, including longitudinal research on micronutrient status, macronutrient requirements, changes in dietary patterns and food choices, musculoskeletal outcomes, unique dosing schedules, and post-cessation maintenance to optimise safety, efficacy, and the patient experience.","42420258":"ID: 42420258\nTitle: L-2-Hydroxyglutarate sensitizes ferroptosis through ATF3/CHAC1-mediated glutathione degradation in hepatocellular carcinoma.\nAbstract: Ferroptosis is an iron-dependent form of regulated cell death driven by lipid peroxidation and glutathione (GSH) depletion and represents a therapeutic vulnerability in hepatocellular carcinoma (HCC). While canonical ferroptosis regulation centers on cystine uptake and GPX4-mediated GSH utilization, the endogenous metabolic pathways governing ferroptosis sensitivity in liver tumors remain incompletely understood. Here, using a metabolic-scale CRISPR activation screen integrated with transcriptomic and metabolomic analyses, we identify L-2-hydroxyglutarate dehydrogenase (L2HGDH) as a potent antagonist of ferroptosis in HCC. We demonstrate that L2HGDH is frequently suppressed in liver tumors, leading to pathological accumulation of its substrate L-2-hydroxyglutarate (L2HG). Elevated L2HG sensitizes HCC cells to ferroptosis both in vitro and in vivo. Mechanistically, L2HG acts as a metabolic-epigenetic regulator that inhibits 2-oxoglutarate-dependent dioxygenases, induces histone hypermethylation, and remodels chromatin accessibility to activate an ATF3-dependent transcriptional program. This program induces the glutathione-degrading enzyme CHAC1, thereby accelerating GSH degradation to 5-oxoproline and disrupting redox homeostasis. Notably, L2HG-induced ferroptosis occurs independently of impaired cystine uptake, transsulfuration pathway activity, or increased GPX4-mediated GSH utilization, revealing a non-canonical ferroptosis mechanism driven by enhanced GSH catabolism. Consistent with these findings, genetic targeting of L2HGDH suppresses tumor growth, elevates L2HG levels, enhances GSH degradation, and promotes ferroptosis in HCC xenograft models. Collectively, our study identifies the L2HGDH-L2HG axis as a previously unrecognized metabolic checkpoint controlling ferroptosis sensitivity in liver cancer and uncovers glutathione degradation as a therapeutically exploitable vulnerability for ferroptosis-based treatment strategies in HCC.","42420952":"ID: 42420952\nTitle: Association between food-based dietary inflammatory index and dental health: results from Bandare-Kong Non-Communicable Disease (BKNCD) cohort.\nAbstract: Oral health is strongly related to diet, and pro-inflammatory dietary patterns may worsen dental diseases through systemic inflammation. This study examined the relationship between the Food-based Dietary Inflammatory Index (FDII) and dental health, assessed by the DMFT index (Decayed, Missing, and Filled Teeth index), in Iranian adults. This cross-sectional study analyzed baseline data from the Bandare-Kong cohort, a subset of the prospective PERSIAN study, including 3,630 Iranian adults aged 35-75 years. Dietary intake was assessed using a validated food frequency questionnaire, and FDII was used to assess the inflammatory potential of participants 'dietary patterns. Participants were classified into tertiles based on their E-FDII scores. The DMFT index was calculated as the sum of decayed, missing (due to caries), and filled permanent teeth. Generalized linear regression models (GLR) were used to examine the association between FDII scores and dental health outcomes. In the total population, higher dietary inflammatory potential was suggestively associated with poorer oral health. Compared with T1, T2 and T3 of E-FDII were related to fewer teeth [β = - 0.9 (-1.2 to - 0.6) and - 1.0 (-1.5 to - 0.8)], a higher number of decayed teeth [0.3 (0.1 to 0.5) and 0.4 (0.2 to 0.8)], more missing teeth [0.9 (0.6 to 1.3) and 1.1 (0.8 to 1.4)], and higher DMFT scores [1.1 (0.6 to 1.5) and 1.5 (1.0 to 1.9), p-trend = 0.001] in the adjusted model, while the number of filled teeth showed no clear association. Stratified analyses indicated that these suggestive trends were more apparent in women and middle-aged adults. Our findings indicate that higher diet-related inflammatory potential is associated with poorer dental health in a representative sample of Iranian adults. Given the small effect sizes, the clinical relevance may be limited. Longitudinal studies are warranted to clarify the temporal relationship and underlying mechanisms.","42422404":"ID: 42422404\nTitle: Diet Quality, Dietary Inflammatory Potential, and All-Cause Mortality in U.S. Adults With Asthma-COPD Overlap.\nAbstract: Asthma-COPD overlap (ACO) is associated with increased mortality and disease burden compared to asthma or COPD alone. Diet, a modifiable risk factor, influences inflammation and lung health, yet its impact on ACO mortality remains understudied. This study investigates the synergistic effects of the Healthy Eating Index (HEI-2015) and Dietary Inflammatory Index (DII) on all-cause mortality in ACO patients. Using data from the National Health and Nutrition Examination Survey (NHANES) 2007-2018, we analyzed 609 U.S. adults with ACO, defined by clinical and spirometric criteria. Dietary patterns were assessed via HEI-2015 (diet quality) and DII (inflammatory potential). Cox proportional hazards models evaluated associations with mortality, adjusting for sociodemographic, lifestyle, and clinical confounders. Restricted cubic spline analyses explored non-linear relationships, and Least Absolute Shrinkage and Selection Operator (LASSO) regression identified key dietary components for a prognostic nomogram. Healthier diets (higher HEI-2015) were associated with lower mortality risk (HR = 0.98, 95% CI: 0.97-0.99, highest quartile), while pro-inflammatory diets (higher DII) increased risk (HR = 1.13, 95% CI: 1.04-1.22). The combination of healthy and anti-inflammatory diets showed the strongest protective effect (HR = 0.68, 95% CI: 0.47-0.98). LASSO regression identified PUFA, total dairy, whole fruit, and n-6 fatty acids as key predictors, incorporated into a nomogram with moderate predictive accuracy (AUC: 0.64-0.67). Kaplan-Meier curves confirmed better survival in low-risk dietary groups (p < 0.0001). Subgroup analyses showed stronger effects in mild drinkers and non-hypertensive patients. High-quality, anti-inflammatory diets synergistically reduce mortality in ACO patients. Targeted nutritional interventions emphasizing whole fruits, dairy, and healthy fats may improve outcomes. Future research should validate these findings through interventional trials.","42422477":"ID: 42422477\nTitle: Different treatments regulate starch degradation, ethylene biosynthesis, and energy metabolism involved in the preparation and shelf life of ready-to-eat kiwifruit.\nAbstract: The rapid senescence of ready-to-eat kiwifruit limits its commercial expansion. We hypothesized that starch degradation, ethylene biosynthesis, and energy metabolism are key metabolic pathways regulating the edible window of ready-to-eat kiwifruit. This study investigated the effects of alternating temperature, ethanol, ethylene, and control treatments on post-ripening behavior and shelf life of kiwifruit. Fruit were treated until their soluble solids content reached 13%-15%, followed by application of 0.5 μL·L-1 1-methylcyclopropene. Ethanol and ethylene treatments accelerated ripening and shortened shelf life, as reflected by elevated respiration, ethylene bursts, accelerated starch degradation, and enhanced energy metabolism. Conversely, alternating temperature suppressed physiological transitions, maintained energy homeostasis, and extended the edible window. At the molecular level, starch degradation genes (AcBAM3.1/3.5/9), ethylene biosynthesis genes (AcACO1/2), and the energy metabolism-related gene (Acc10529/PFK1) were significantly upregulated in ethanol- and ethylene-treated fruit during the pre-ripening phase. In contrast, fruit exposed to alternating temperature maintained lower expression of these genes throughout storage without impeding normal ripening. This reduction in transcriptional activity was associated with improved cellular energy balance and reduced postharvest spoilage. Overall, these findings provide insights into the physiological and transcriptional responses of postharvest kiwifruit to different ripening treatments and identify candidate pathways influencing shelf life.","42422989":"ID: 42422989\nTitle: Association between dietary index for gut microbiota and all-cause and cardiovascular disease mortality in patients with gout and hyperuricemia: A prospective cohort study.\nAbstract: ObjectiveGout and hyperuricemia (HUA) are common metabolic disorders associated with increased all-cause and cardiovascular disease (CVD) mortality, and gut microbiota-modulating diets may influence prognosis. We aimed to evaluate whether the Dietary Index for Gut Microbiota (DI-GM) is associated with all-cause and CVD mortality among adults with gout or HUA.MethodsIn this prospective cohort study, we analyzed data from 5,325 adults with gout or hyperuricemia enrolled in the 2007-2018 National Health and Nutrition Examination Survey (NHANES). DI-GM scores were calculated using 24-hour dietary recall data, incorporating 14 predefined food components (10 beneficial and 4 harmful to gut microbiota). Mortality status was ascertained through linkage to the National Death Index up to December 31, 2019. Cox proportional hazards models were applied to estimate hazard ratios and 95% confidence intervals, adjusting for demographic, lifestyle, and clinical factors. Sensitivity analyses, interaction tests, and stratified analyses were conducted to assess robustness.ResultsDuring a median follow-up of 6.5 years (35,625 person-years), 603 deaths occurred, including 197 from CVD. Higher DI-GM scores were associated with significantly lower mortality risk. Participants with DI-GM scores ≥6 had a 33% reduced risk of all-cause mortality and a 45% reduced risk of CVD mortality compared to those with scores ≤ 4. Each one-point increase in DI-GM score was associated with an 8% decrease in all-cause mortality and a 13% decrease in CVD mortality. Results were consistent across all sensitivity analyses.ConclusionsIn individuals with gout or hyperuricemia, higher DI-GM scores were independently associated with reduced all-cause and CVD mortality. These findings suggest that gut microbiota-friendly dietary patterns may provide prognostic value and offer a potential target for dietary interventions in this high-risk population.","42424078":"ID: 42424078\nTitle: Sex Differences in Long-Term Overall and Cause-Specific Mortality in Patients With Cirrhosis.\nAbstract: Evidence on sex differences in the natural history of cirrhosis and cause-specific mortality remains limited. To compare long-term all-cause and cause-specific mortality between male and female patients with cirrhosis. This population-based retrospective cohort study included hospitalized adults with cirrhosis identified from the California Department of Healthcare Access and Information database from January 2005 to December 2019. Propensity score matching (PSM) was used to balance baseline characteristics between male and female patients. Data were analyzed from August to December 2025. Sex (females compared with males). Ten-year all-cause and cause-specific (liver-related [hepatocellular carcinoma (HCC) and non-HCC], non-liver-related [cardiovascular and other]) mortality were assessed. Hazard ratios (HRs) of all-cause death were estimated using Cox models, and subdistribution hazard ratios (sHRs) of cause-specific death and receipt of liver transplantation (LT) were estimated using Fine-Gray competing risk models, stratified by age, race, ethnicity, social deprivation level, cirrhosis cause, and cirrhosis severity. Among 316 957 patients with cirrhosis (124 228 females [39.2%]; mean [SD] age, 61.4 [14.4] years; 192 729 males [60.8%]; mean [SD] age, 58.8 [13.1] years), PSM yielded 110 044 male-female pairs with balanced characteristics. Compared with males, females had lower estimated 10-year cumulative all-cause mortality (51 703 patients [58.2%] vs 53 310 patients [59.8%]), cardiovascular mortality (9215 patients [10.5%] vs 10 531 patients [11.9%]), and HCC-related mortality (3255 patients [3.6%] vs 4745 patients [5.4%]), but higher non-HCC liver-related mortality (18 572 patients [20.9%] vs 16 993 patients [19.0%]). In Cox models, females had a lower hazard of all-cause death (HR, 0.94; 95% CI, 0.93-0.96). In Fine-Gray models, females had lower hazards of cardiovascular-related (sHR, 0.86; 95% CI, 0.84-0.89) and HCC-related (sHR, 0.68; 95% CI, 0.65-0.71) death, but a higher hazard of non-HCC liver-related death (sHR, 1.09; 95% CI, 1.07-1.12). Stratified analyses suggested that females younger than 50 years (sHR, 1.06; 95% CI, 1.02-1.11) and those with alcohol-associated cirrhosis (sHR, 1.12; 95% CI, 1.08-1.17) had higher hazard of liver-related mortality, and females were less likely to undergo LT (sHR, 0.77; 95% CI, 0.66-0.89). In this cohort study of patients with cirrhosis, males had slightly higher all-cause mortality largely due to higher cardiovascular and HCC-related mortality, while females had higher non-HCC liver-related mortality; females younger than 50 years and those with alcohol-associated cirrhosis had higher liver-related mortality but lower rates of LT. These sex disparities warrant specific consideration in future guidelines for disease monitoring and transplant allocation.","42424249":"ID: 42424249\nTitle: Development and validation of a food group system for intake control in people with diabetes: SMARTCLOTH-Database.\nAbstract: This study presents the development and validation of the SMARTCLOTH-Database, a structured food group system designed to support dietary management for individuals with diabetes. The database organises foods into 20 nutritionally coherent groups, distinguishing between raw and cooked forms, based on Spanish dietary patterns and statistical criteria. Nutritional values were calculated using weighted averages derived from national food consumption data and multiple international food composition databases. To validate the system, a computational tool was developed to generate daily menus automatically and compare nutritional outputs against a gold standard reference (BDCA). The comparison showed small mean differences (less than ±22 kcal, < 2 g carbohydrates, < 0.6 g protein, and <1.5 g lipids), with high concordance demonstrated through intraclass correlation coefficients (ICC ≥ 0.75) for carbohydrates and proteins across most analyses. These results indicate that the SMARTCLOTHDatabase provides accurate and reliable estimates of macronutrient content, making it suitable for integration into digital tools aimed at improving dietary self-management in people with diabetes.","42425417":"ID: 42425417\nTitle: Beyond metabolism: towards a Dynamic Endocrine Framework for Eating Behaviour under Gender-Affirming Hormone Therapy.\nAbstract: Eating behaviour arises from complex interactions among biological, psychological, and environmental processes, yet existing conceptual models rarely address populations undergoing intentional endocrine modulation. Gender-affirming hormone therapy (GAHT) induces sustained changes in sex steroid profiles with downstream effects on metabolic signalling pathways involved in appetite regulation, body composition, and energy balance. Despite increasing attention to the metabolic and clinical effects of GAHT, its potential contribution to eating behaviour remains insufficiently integrated into existing theoretical perspectives. This review synthesises current evidence on the endocrine, behavioural, and structural determinants of eating behaviour in transgender and gender-diverse (TGD) populations, highlighting major methodological and conceptual limitations, including the predominant focus on metabolic outcomes, limited assessment of dietary intake and eating behaviour, and lack of validated measurement tools for TGD populations. To address these gaps, we propose a Dynamic Endocrine Framework for Eating Behaviour, in which intentional endocrine modulation initiates the adaptive reorganisation of a multilevel system from which eating behaviour emerges. Within this framework, endocrine modulation interacts continuously with behavioural interpretation, structural embedding, and adaptive feedback across time rather than functioning as an isolated or predominant determinant of behavioural outcomes. Eating behaviour is thus conceptualised as an emergent, context-dependent property of a continuously evolving adaptive system. Rather than proposing new biological mechanisms, the framework integrates evidence from endocrinology, behavioural nutrition, transgender health, psychology, and food environment research, providing a theoretical foundation for future empirical studies and for more comprehensive clinical and structurally informed public health approaches to TGD populations.","42425454":"ID: 42425454\nTitle: Effect of Carbohydrate-Restricted Dietary Patterns Based on Prescribed and Self-Reported Intake in Adults with Overweight and Obesity: A Systematic Review and Meta-Analysis.\nAbstract: Carbohydrate (CHO) restriction has regained attention as a dietary approach for weight management and cardiometabolic health, though evidence supporting its effectiveness remains controversial, particularly regarding degree of restriction. Examine effects of CHO-restricted versus higher CHO dietary approaches on weight- and cardiometabolic-related outcomes in adults with overweight or obesity without other established disease. Searches of MEDLINE, CINAHL, and Cochrane databases identified relevant randomized controlled trials (RCTs) published from 2010-2025. Primary outcomes were anthropometric outcomes (body weight, BMI, waist circumference, fat and lean body mass) and glycemic outcomes (fasting blood glucose, HbA1c). Meta-analyses were conducted using random-effects models for an outcome of interest. Heterogeneity was assessed using I2, evidence certainty using the GRADE methodology, and publication bias was assessed using Begg and Egger's statistic and by generating funnel plots. Twenty-three RCTs, represented in 28 articles, were included. Degree of CHO restriction varied across studies, with self-reported intake often less restrictive than prescribed levels. CHO restriction resulted in modest but significant reductions in body weight (Mean difference (MD): -1.32kg, 95% CI: -2.03, -0.61), waist circumference (MD: -0.89 cm, 95% CI: -1.44, -0.34), and fat mass (standardized mean difference (SMD): -0.29, 95% CI: -0.48, -0.10) compared to higher CHO diets. CHO restriction reduced fasting blood glucose (MD: -0.08mmol/L, 95% CI: -0.17, 0.00), HbA1c (MD: -0.16%, 95% CI: -0.28, -0.04), triglycerides (MD: -0.17mmol/L, 95% CI: -0.26, -0.08), and systolic blood pressure (MD: -4.86mmHg, 95% CI: -6.60, -3.11). CHO restriction (<45% total daily energy intake) likely provides modest benefits for weight management and certain cardiometabolic risk factors in adults with overweight or obesity.","42425640":"ID: 42425640\nTitle: Controlling nitrosamine accumulation in dry fermented sausages using Lacticaseibacillus rhamnosus H7: The role of physicochemical drivers and precursor depletion.\nAbstract: Lacticaseibacillus rhamnosus H7, selected for its superior nitrite degradation capacity (94.60%) in nitrite-supplemented MRS broth, was evaluated as a starter culture in dry fermented sausages at different inoculation levels. Inoculation significantly enhanced product safety, achieving up to 44.82% reduction in total nitrosamines. Simultaneously, total biogenic amines were reduced by up to 33.17%, particularly putrescine, cadaverine, tyramine, and histamine. Regarding product quality, the strain promoted acidification, maintained low water activity, and effectively reduced nitrite levels. Both inoculation levels induced moderate lipid oxidation while preserving the characteristic red color typically associated with nitrite curing. Notably, the lower inoculation level (106 CFU/g) achieved an optimal balance between safety enhancement and sensory preservation, while also promoting the release of free amino acids. Statistical modeling identified acidification and precursor depletion as key drivers suppressing nitrosamine formation. Overall, an appropriate inoculation level of L. rhamnosus H7 effectively improved the safety and maintained the quality of dry fermented sausages, demonstrating its potential as a functional starter culture.","42426889":"ID: 42426889\nTitle: Exploring life cycle and health-related food taboos and their associated reasons among Puntland - Somalia communities: a mixed methods cross sectional study.\nAbstract: Food taboos are culturally rooted dietary restrictions that model food choices and many compromise nutritional status specifically among vulnerable populations. The study examined the prevalence of food taboos, tabooed foods and explored reasons for their existence among different segments of Puntland communities. A community based mixed methods cross-sectional study was conducted between September and December across the nine regions of Puntland state of Somalia. A total of 290 participants were selected using multi-stage sampling. Quantitative data were collected using structured questionnaires while qualitative data were obtained through 18 key informant interviews and 37 Focus Group Discussions (FGDs) involving pregnant and lactating women, elderly men and women, women of reproductive age and adult men. Data on demographic characteristics were analyzed using SPSS version 31, while qualitative data were analyzed thematically using systematic text condensation. Overall, 88% of participants reported the existence of food taboos in their communities. Pregnancy and lactation were the life stages with the most restrictions (32%) and the least were during menstruation (12%). Commonly tabooed foods during pregnancy included honey, ghee, sheep meat, chili, papaya and whole grains primarily due to beliefs linking them to miscarriage, fetal deformities and labor complications. Liver was universally restricted for children under two years due to perceived speech delay. Men also faced prohibitions such organ meats except liver, animal head, neck and leg meat, considered foods for females and associated with shame, weakness and cowardice. Regional variations were observed with certain taboos being specific to regions, mostly Mudug and Eyl district of Nugaal region. Food taboos are common throughout Puntland but they are more rampant in Mudug region and Eyl district of Nugaal region. Some taboos reported during menstruation and illness have some scientific backup and may contribute to better management of these conditions. However, taboos like those reported during pregnancy and lactation may reduce dietary diversity and negatively impact overall nutrition and health outcomes in vulnerable groups.","42427282":"ID: 42427282\nTitle: Pregnant Women With Gestational Diabetes Mellitus and High Consumption of Tryptophan-Rich Foods Show Increased Levels of 6-Sulfatoxymelatonin in Urine.\nAbstract: Gestational diabetes mellitus (GDM) is associated with metabolic and inflammatory alterations that may influence melatonin metabolism. This study evaluated associations between dietary intake of tryptophan-rich foods, urinary 6-sulfatoxymelatonin, and serum tumor necrosis factor-alpha (TNF-α) levels in pregnant women with GDM. A cross-sectional study included 34 women with GDM and 18 with normal-risk pregnancies. Dietary habits were assessed using a validated food frequency questionnaire (FFQ). Serum TNF-α and first-morning urinary 6-sulfatoxymelatonin levels were measured by ELISA. Associations were evaluated using generalized linear models (GLMs), adjusting for maternal age, body mass index (BMI), gestational age, and sleep quality. Women with GDM reported a significantly higher frequency of consumption of tryptophan-rich foods, particularly milk and dairy products (p < 0.01) and fruits (p < 0.05). The GDM group also exhibited higher urinary 6-sulfatoxymelatonin (p = 0.002) and serum TNF-α levels (p = 0.023). In multivariable models, GDM remained significantly associated with higher urinary 6-sulfatoxymelatonin levels, whereas TNF-α concentrations were primarily associated with maternal characteristics and interaction effects. GDM was associated with higher urinary 6-sulfatoxymelatonin and TNF-α levels despite greater reported intake of tryptophan-rich foods. These findings highlight associations between dietary precursors, melatonin metabolism, and inflammatory markers in hyperglycemic pregnancy and underscore the need for longitudinal studies to clarify underlying mechanisms.","42428198":"ID: 42428198\nTitle: Methodological Considerations in Meta-Analyses Examining Irregular Dietary Patterns and Esophageal Cancer Risk.\nAbstract: Irregular dietary patterns have been linked to an increased risk of esophageal cancer in observational meta-analyses.

This editorial highlights key concerns, including substantial between-study heterogeneity, inconsistent definitions of dietary irregularity, limited power to assess publication bias, and residual confounding inherent to observational research. Variability in esophageal cancer subtypes and cultural dietary practices further complicates pooled risk estimation. While existing evidence underscores the potential relevance of meal regularity in cancer prevention, cautious interpretation is warranted. Future studies using standardized exposure definitions and subtype-specific analyses are needed to improve the reliability of meta-analytic findings.","42428758":"ID: 42428758\nTitle: Health literacy, dietary behavior and body mass index in male and female Norwegian conscripts. A cross-sectional study.\nAbstract: Health literacy (HL) is an important determinant of health behaviors, including diet. In military populations, optimal nutrition is critical for physical performance, readiness, and long-term health. In Norway, first-time military service provides a unique opportunity to influence young conscripts' health habits. This study investigates the relationship between HL and dietary patterns, body mass index (BMI), and meal adherence among Norwegian conscripts, with an emphasis on potential sex differences. A cross-sectional study. This cross-sectional study included Norwegian conscripts completing first-time military service. HL was measured using the validated HLS-Q12 instrument. Dietary behaviors, meal patterns, and BMI were assessed using self-reported questionnaire data. A digital questionnaire was sent to Norwegian conscripts completing their first-time military service in 2022 (n=9,991). A total of 2,225 conscripts consented to participate in the study. The survey assessed dietary habits across different military settings, self-reported diet quality, and HL using the HLS-Q12 tool. BMI was calculated from self-reported height and weight. Statistical analyses included chi-square tests and Pearson correlation to explore associations between HL, diet, and BMI. Significant associations were observed between HL and several dietary variables; however, most associations were weak in magnitude. Higher HL was associated with more regular meal patterns and better self-reported diet quality. Additionally, differences between sexes were observed, but effect sizes were generally small. More than half of conscripts had an adequate HL, with males scoring significantly higher than females. Conscripts with adequate HL were more likely to rate their diet as good, follow meal recommendations, and maintain a normal BMI. However, no significant association between HL and BMI was found in the total population; differences appeared in sex-stratified analyses, among female conscripts. Independently of HL, unhealthy snacking and high-sugar drink consumption were more common during field training, whereas conscripts with inadequate HL (iHL) reporting higher sugary snack intake at home. Adequate HL was weakly but significantly correlated with higher self-reported diet quality, more frequent adherence to regular meals, and lower sugary snack consumption. This could mean that HL was associated with self-reported dietary intentions but not outcomes like BMI. HL may be associated with dietary behaviors among conscripts. However, given the weak associations and study limitations, the findings should be interpreted with caution. Although more than half of the conscripts had adequate HL, iHL was prevalent among Norwegian conscripts. Poorer self-reported diet quality and lower adherence to regular meal patterns is associated with iHL, particularly during field training. No significant associations was found between HL and BMI. The findings suggest a need for tailored education to improve HL and behavior change, to promote healthier dietary habits during military service.","42429437":"ID: 42429437\nTitle: Food practices and nutritional coping strategies of university students during Sri Lanka's economic crisis: An online survey.\nAbstract: BackgroundThe recent global economic crisis has doubled poverty levels, yet its impact on university students' dietary behaviours remains underexplored.ObjectiveTo investigate the food practices and nutritional coping strategies employed by university students during the prevailing economic crisis in Sri Lanka.MethodsAn online-based cross-sectional survey was conducted with 206 students from a selected university. The questionnaire contained demographic information, a seven-day dietary recall, financial characteristics, and nutritional coping strategies among university students. Descriptive statistics and multivariate logistic regression analyses were performed using the Statistical Package for the Social Sciences version 30.0 to explore the association between selected economic factors and food choice outcomes among the participants.ResultsThe sample consisted of 52.9% females, with the majority of participants falling within the 23-25-year age group. A significant portion (64.6%) reported a reduction in household income over the past three months, and 84.0% had adopted cost-cutting strategies to manage household finances. Notably, 93.7% of students had reduced their university-related expenses, including food (66.5%). Nutritional coping strategies included replacing main meals with low-cost snacks (84.5%) and switching to bakery items (53.4%). Multivariate logistic regression analysis revealed that students who reduced spending on university-related expenses were 2.5 times more likely to consume bakery items (odds ratio (OR) = 2.21; 95% confidence interval (CI): 0.275-6.61; p < 0.05), while the odds of consuming low-cost starchy food were 2.3 (OR = 2.30; 95% CI: 1.14-4.79; p < 0.05) among those who reduced household income.ConclusionThis study demonstrates that a reduction in household income and adjustments to household and university-related expenditures during Sri Lanka's economic crisis were associated with less favourable dietary patterns among undergraduate students and with the use of nutritional coping strategies that may compromise dietary adequacy.","42429521":"ID: 42429521\nTitle: A Systematic Review and Meta-analysis on the Salt and Sodium Intake in India.\nAbstract: In India, estimates of salt intake vary widely due to cultural and regional dietary patterns, and an updated comprehensive synthesis was lacking.

The pooled mean salt intake from 30 studies was 9.01 g/day (95% confidence interval [CI]: 8.23-9.79), whereas the mean sodium intake from 23 studies was 3.49 g/day (95% CI: 2.72-4.25), both exceeding the World Health Organization-recommended limits. The pooled prevalence of high salt intake was 61% (95% CI: 48%-73%), with wide variation by intake definition. Subgroup analyses showed higher intake in rural populations, males, and hypertensive individuals. Salt and sodium intake in India remains significantly above recommended levels, with considerable variability across regions and populations.","42430158":"ID: 42430158\nTitle: Eco-Focused Menu Labels on Full Meal Orders From Fast-Food Restaurants: A Randomized Clinical Trial.\nAbstract: Promoting environmentally sustainable dietary patterns can benefit both population and planetary health. Ecolabels on restaurant menus could promote healthful and sustainable choices, but evidence is needed on effects in different restaurant types. To test the effects of different ecolabel designs on menus from 2 fast-food restaurants on the healthfulness of full meal orders, compared to a control label. This randomized clinical trial was conducted online in a nationally representative sample of adults (≥18 years) in the US in April 2025. Participants were recruited from the NORC AmeriSpeak survey panel to participate in this experiment. Participants were randomized via an automated process within the survey platform to 1 of 5 label conditions: (1) control: QR code; (2) low-climate-impact labels; (3) traffic-light labels (TLLs); (4) high-climate-impact labels; or (5) grade-scale labels and asked to order lunch from 2 fast-food menus (1 burger-focused and 1 sandwich-focused). The primary outcome was the healthfulness of meals ordered based on a modified Nutrient Profile Index (NPI) score. Other outcomes included the estimated greenhouse gas emissions (GHGE), calorie and nutrient content, and cost of selected meals, as well as perceptions of labels and knowledge about the climate contribution of different foods. Among the 6210 participants (3274 [51.0%] women; mean [SD] age, 48.1 [18.1] years), 1236 participants were randomized to the control group; 1249 to low-climate-impact labels, 1243 to high-climate-impact labels, 1235 to TLLs; and 1247 to grade-scale labels. Demographic characteristics were similar across groups. Only the TLL was effective at promoting more healthful food choices in the burger restaurant compared to the control label (mean [standard error] NPI score: 49.93 [0.18] points vs 49.25 [0.18] points; P < .001). There were no ecolabel effects on NPI score in the sandwich restaurant. Compared to control, the TLL led to 15.2% lower GHGE for meals in the burger restaurant and 29.8% lower GHGE for meals in the sandwich restaurant. The TLL was the most noticeable (78.30% [95% CI, 75.35%-81.26%]; P < .001) and had the highest percentage of participants who correctly reported what the label was about (88.72% [95% CI, 86.04%-91.39%]; P < .001). There were no differences in the overall cost of the meals selected by label condition. Findings from this web-based randomized clinical trial showed that TLL-style ecolabels on restaurant menus may be an effective strategy to promote more sustainable and, in some instances, more healthful food choices without increasing consumer costs.

Previous research suggests that unhealthy lifestyle behaviors-including poor diet, insufficient physical activity, inadequate sleep, and ineffective stress management-may negatively impact life satisfaction among young adults. This cross-sectional study examined the relationship between lifestyle and life satisfaction among newly enrolled undergraduate students at Tehran University of Medical Sciences in 2024. Participants completed structured questionnaires assessing multiple lifestyle domains (diet, physical activity, sleep, smoking, alcohol use) and life satisfaction using validated Iranian questionnaires. Lifestyle scores were categorized as \"healthy\" or \"unhealthy,\" and life satisfaction as \"good\" or \"poor.\" Associations were analyzed using Pearson's chi-square test and multivariable logistic regression, adjusting for age, sex, socioeconomic status, and anxiety. Overall, of the 419 students, 294 (70.2%) reported good life satisfaction. Socioeconomic status and anxiety levels differed significantly across life satisfaction groups (p < 0.001). Students with healthier dietary patterns reported higher life satisfaction (76.6% vs. 60.4%, p = 0.02). Multivariable analysis indicated that students with healthy lifestyles had significantly higher odds of good life satisfaction compared to those with unhealthy lifestyles (adjusted odds ratio [aOR = 1.91; 95% confidence interval [CI]: 1.10,3.35; p = 0.02). Each one-unit increase in lifestyle score was associated with a 28% increase in the odds of good life satisfaction (aOR = 1.28; 95% CI: 1.05,1.57; p = 0.02). Unhealthy lifestyle behaviors are negatively associated with life satisfaction among new university students. Interventions promoting balanced nutrition, regular physical activity, adequate sleep, and overall health-conscious behaviors may enhance students' life satisfaction and well-being.","42431155":"ID: 42431155\nTitle: Predictors of food waste quantities and composition: A nationwide diary study of Swiss households.\nAbstract: In this study, we aimed to quantify the average amount of avoidable food wasted in Swiss households using a novel web-based diary method. We also aimed to identify under-explored predictors of food waste, including sociodemographic factors (e.g. linguistic region), psychological factors (e.g. plate-clearing tendencies and perceived health risk), and eating habits (e.g. dietary patterns and frequency of dinner preparation). We collected data from a random stratified sample of 515 households in Switzerland across three linguistic regions. Food waste data for 14 food groups were collected via a web application, whereas personal and household characteristics were gathered separately through online surveys. We identified food waste predictors using correlation and regression analyses. On average, the participants reported wasting 401.9 grams (standard deviation = 394.3) of food per capita per week. Overall, age, household size, linguistic region, and plate-clearing tendencies were key predictors of food waste. Households in Italian-speaking regions wasted less food than those in German-speaking regions. Additionally, participants with stronger plate-clearing tendencies wasted less food than those with weaker tendencies. This finding might thus highlight a relevant trade-off between reducing food waste on plates and increased overeating (metabolic food waste), which may result from a stronger tendency to clear one's plate. We also observed that 'non-meat eaters' generated more waste of starchy side dishes than 'meat eaters'. Our findings highlight the need for future interventions to address cultural, behavioural, and dietary factors to reduce avoidable food waste and offer insights for designing targeted strategies for specific populations and food categories.","42431320":"ID: 42431320\nTitle: Temporal changes in Mediterranean-style diet adherence and ultra-processed food exposure in relation to psychological distress at follow-up: A 12-year analysis of the Melbourne collaborative cohort study.\nAbstract: Consuming a Mediterranean-style diet is associated with lower depression risk. Concurrently, the ultra-processed food (UPF) dietary pattern is associated with increased depression risk. As dietary patterns shift over time, it is important to understand how changes in these dietary patterns relate to psychological distress as an indicator of depression. We used a subset of data from the Melbourne Collaborative Cohort Study (n = 21,718). Dietary intake was assessed at baseline and follow-up using food frequency questionnaires, from which Mediterranean diet scores and UPF intake were derived. Psychological distress at follow-up was measured using the Kessler Psychological Distress Scale (K10). We assessed change in diet from baseline to follow-up using generalised estimating equations to account for repeated measures, and associations of change in diet with depression using Poisson regression. Analyses were conducted in the overall sample and by birthplace (Australian/New Zealand/Northern European; Southern European). Participants increased both their adherence to the Mediterranean-style diet (β = 0.28, 95%CI = 0.25-0.31) and exposure to UPFs (β = 55.20 g/day, 95%CI = 51.71-58.69). Stratification by birthplace showed similar patterns, except for Southern European participants where no clear change in UPF exposure was observed (β = -2.38 g/day, 95%CI = -12.35-7.59). One-point increases in Mediterranean diet score between baseline and follow-up were associated with a 5% lower risk of psychological distress (RR = 0.95, 95%CI = 0.93-0.98), while increasing UPF by 90 g/day was associated with a 5% higher risk (RR = 1.05, 95%CI = 1.03-1.07). Adherence to Mediterranean-style diet and UPF exposure increased over time across the overall sample, although patterns varied by region, and these changes were associated with opposing risks of psychological distress.","42431406":"ID: 42431406\nTitle: Probiotics for enhanced tissue carotenoid status: A double-blind, randomized controlled trial.\nAbstract: Skin carotenoid status (SCS) is a reliable indicator of carotenoid intake and has been shown to reflect interindividual variability in carotenoid metabolism and absorption. While probiotics are known to enhance micronutrient status, their impact on phytochemicals like carotenoids remains unstudied. To determine whether the probiotic strain B. subtilis Rosell®-179 can potentiate the enhancing effect of carotenoid supplementation on carotenoid status and various health markers. A 10-week, double-blind, randomized controlled trial (RCT) involving 37 premenopausal women (average age of 40) was conducted. All participants took two supplements daily: a mixed carotenoid supplement (17 mg of total carotenoids) and either a probiotic or a placebo. The primary outcome was SCS measured using a spectrophotometer. Secondary outcomes included plasma carotenoids and markers of antioxidant capacity, inflammation, and skin health (e.g., hydration, wrinkling). Dietary intake, physical activity, quality of life, and sleep were also monitored. Repeated measures were analyzed using linear mixed models with treatment and time (week 0, 5 and 10) as factors. SCS increased from baseline in both groups, with the probiotic group showing a larger estimated increase than placebo at week 10 by 1.1 units (p=0.056; 95% CI, 2.25 to -0.05). Both groups increased plasma carotenoids from baseline to week 5 but did not continue to increase. There were no notable changes in plasma antioxidant capacity, immune status or skin health measures. These findings indicate the potential of B. subtilis Rosell®-179 to enhance SCS in healthy premenopausal women. The study was registered on August 12th, 2020 at clinicaltrials.gov (NCT04511052): https://clinicaltrials.gov/study/NCT04511052.","42431462":"ID: 42431462\nTitle: Non-advanced age-related macular degeneration: current concepts and future perspectives.\nAbstract: Non-advanced age-related macular degeneration (AMD), encompassing early and intermediate stages, represents a critical therapeutic window before irreversible central vision loss. Traditionally defined by drusen size and pigmentary abnormalities on color fundus photography, disease characterization has evolved substantially with the integration of multimodal imaging biomarkers. Contemporary imaging enables detailed structural phenotyping, including reticular pseudodrusen (also known as subretinal drusenoid deposits), hyperreflective foci, and incomplete retinal pigment epithelium and outer retinal atrophy, which refine risk stratification and provide insight into progression toward advanced disease. Functional assessment has expanded beyond best-corrected visual acuity to include low-luminance visual acuity, contrast sensitivity, dark adaptation, and microperimetry, many of which are more sensitive to early dysfunction. However, standardization and regulatory approval of these endpoints remain ongoing challenges. Non-advanced AMD arises from complex interactions among genetic susceptibility, aging, environmental exposures, and systemic metabolic factors. Smoking remains the strongest modifiable risk factor, while Mediterranean dietary patterns appear protective. Currently, no pharmacologic therapies are approved for non-advanced AMD. The Age-Related Eye Disease Study formulations remain the only interventions proven to reduce progression in high-risk individuals. Emerging approaches, including subthreshold laser therapy and photobiomodulation, show preliminary promise but require validation in robust and adequately powered randomized clinical trials. Recent consensus efforts emphasize biomarker-driven classification and highlight the heterogeneity of AMD phenotypes across populations. Future research priorities include validation of quantitative imaging and functional endpoints, integration of artificial intelligence-based predictive models, and development of targeted therapies to delay progression. These endevours will be essential to advance precision prevention strategies.","42431670":"ID: 42431670\nTitle: Complementary feeding indicators among children aged 6-23 months: a cross-sectional study assessing minimum dietary diversity, minimum acceptable diet and dietary patterns in Njombe Town Council, Tanzania.\nAbstract: This study assessed the minimum dietary diversity (MDD), minimum meal frequency (MMF), minimum acceptable diet (MAD) and dietary patterns among children aged 6-23 months in Njombe Town Council. Community-based cross-sectional study. This study was conducted in the Njombe Town Council, which is located in the Njombe region in the southern part of Tanzania. A total of 330 caregivers of children aged 6-23 months were recruited using a multistage probability sampling technique. Data were collected from January to March 2021 using a structured questionnaire adapted from the Process for Promotion of Child Feeding (ProPAN) manual. None. The primary outcomes were the prevalence of MDD, MMF and MAD, assessed according to the 2021 WHO infant and young child feeding indicators. Secondary outcomes included food group consumption and dietary patterns identified using principal component analysis. A total of 330 caregivers of children aged 6-23 months participated in the current study. Nearly half (43.9%; n=145) were aged between 30 and 49 years, with a mean age of 30.28 years and an SD of ±6.119 years. Only 26.36% of children aged 6-23 months achieved MDD, 71.5% achieved MMF and 18.48% met MAD, with a mean dietary diversity score of 3.35±1.6. Predominant foods included grains, roots and tubers (80.91%) and breast milk (90%), while dairy products were the least consumed (7.27%). Three dietary patterns emerged: cereals, roots and tubers; dairy products and eggs; and vitamin A-rich fruits and vegetables. The MDD and MAD attainment in Njombe Town Council are suboptimal, reflecting reliance on staple foods and limited nutrient-rich options. These findings highlight the need for context-specific interventions, including strengthened nutrition education, promotion of diversified diets and agricultural strategies that improve access to nutrient-dense foods to enhance infant and young child nutrition.","42432727":"ID: 42432727\nTitle: Dietary patterns and exploratory gut microbiota profiles associated with diabetic retinopathy and cognitive impairment in type 2 diabetes.\nAbstract: Diabetic retinopathy (DR) and cognitive impairment are closely related complications of type 2 diabetes mellitus (T2DM). Although dietary patterns and gut microbiota have each been linked to these conditions, their combined associations with co-occurring DR and cognitive impairment remain unclear. This study examined dietary patterns and exploratory gut microbiota profiles in relation to co-occurring DR and cognitive impairment in patients with T2DM. In this cross-sectional study, 306 patients with T2DM were classified into four groups: no DR with normal cognition (DMCN), no DR with cognitive impairment (DMCI), DR with normal cognition (DRCN), and DR with cognitive impairment (DRCI). Dietary patterns were derived using principal component analysis. Gut microbiota composition was assessed using 16 S rRNA sequencing in a subset of 108 participants. Multinomial logistic regression was used to examine associations between dietary patterns and group classification, and microbiome analyses included diversity, taxonomic composition, exploratory differential abundance, and diet-microbiota correlations. Four dietary patterns were identified. In fully adjusted models, DP-I and DP-II were associated with higher odds of DMCI and DRCI, respectively, whereas DP-III was associated with lower odds of both DMCI and DRCN. DP-IV showed no significant association. Gut microbiota analyses showed modest but statistically significant group-related differences in community structure, with partial overlap across groups. Exploratory LEfSe analysis identified group-associated taxa, including higher relative abundances of Bifidobacterium, Streptococcus, and Dubosiella in DMCN and of Pseudomonas, Bilophila, and Sarcina in DRCI. However, these genus-level differences were not significant after covariate-adjusted MaAsLin2 analysis with false discovery rate (FDR) correction. Nominal diet-microbiota correlations were observed but were not statistically robust after FDR correction. Dietary patterns were associated with clinical group classification based on DR and cognitive impairment in patients with T2DM. Gut microbiota analyses suggested modest, exploratory group-related differences, but diet-microbiota correlations were not statistically robust after FDR correction. These cross-sectional findings should be interpreted as hypothesis-generating and require validation in larger longitudinal studies.","42433265":"ID: 42433265\nTitle: Real-World Efficacy and Safety of TACE Combined with Lenvatinib and PD-1 Inhibitor in Conversion Therapy for Unresectable Hepatocellular Carcinoma (GUIDANCE007): A Multicenter Retrospective Study.\nAbstract: Transarterial chemoembolization (TACE) combined with lenvatinib has demonstrated efficacy for unresectable hepatocellular carcinoma (HCC). However, real-world evidence on the additional benefit of PD-1 inhibitors in conversion therapy remains limited. This study aimed to investigate the efficacy and safety of triple therapy (TACE, lenvatinib, and PD-1 inhibitors) versus dual therapy (TACE and lenvatinib) in conversion therapy for initially unresectable HCC. This multicenter study was conducted in 20 Chinese tertiary hospitals. Patients received either triple therapy (TLP group, n = 289) or dual therapy (TL group, n = 132). Inverse probability of treatment weighting (IPTW) was used to control for confounding. Multivariate models compared overall survival (OS) and progression-free survival (PFS). From January 2019 to June 2023, 421 consecutive patients were enrolled. After IPTW adjustment, baseline characteristics were well balanced. The TLP group showed superior efficacy: objective response rate 55.1% versus 34.7% (p < 0.001), complete response rate 24.9% versus 14.9% (p = 0.010), and conversion surgery rate 35.5% versus 15.7% (p < 0.001). Median OS was prolonged (31.67 vs. 25.00 months; adjusted HR 0.60, 95% CI: 0.42-0.85, p = 0.001) and median PFS extended (16.47 vs. 12.00 months; adjusted HR 0.65, 95% CI: 0.47-0.93, p = 0.008). Sensitivity analyses including propensity score matching (HR 0.61), landmark analysis (HR 0.64), and time-varying covariate analysis (HR 0.58) confirmed the findings. E-value analysis (2.72) suggested unmeasured confounding alone is unlikely to explain the benefit. Treatment effects were consistent across subgroups. Grade 3-4 adverse events were similar (35.6% vs. 36.4%, p = 0.885), though immune-related adverse events were more frequent in the TLP group. Adding PD-1 inhibitors to TACE plus lenvatinib was associated with improved tumor response, prolonged survival, and higher conversion surgery rates, with an acceptable safety profile. Given the heterogeneity of PD-1 inhibitors and inherent limitations of retrospective design, these findings should be considered hypothesis generating and require verification in prospective randomized controlled trials. Liver cancer is one of the deadliest cancers worldwide. When liver cancer cannot be removed by surgery, doctors use treatments to shrink tumors, so surgery may become possible later. This is called “conversion therapy.” We studied 421 patients from 20 hospitals in China whose liver cancer could not be surgically removed at first. One group received two treatments: TACE (a procedure that blocks blood flow to tumors while delivering chemotherapy directly to them) plus lenvatinib (a pill that stops tumor blood vessel growth). The other group received these same treatments plus a PD-1 inhibitor, which helps the body’s immune system fight cancer. The group receiving all three treatments had better results. More patients saw their tumors shrink (55% versus 35%), and more were able to have surgery to remove their cancer (35% versus 16%). Patients receiving the three-treatment combination also lived longer, about 32 months compared to 25 months. Side effects were similar between groups. The most common included tiredness, changes in liver function tests, and decreased appetite. These findings suggest that adding immune therapy may help more patients with advanced liver cancer live longer and have a better chance of curative surgery. However, this was not a randomized trial, so more research is needed to confirm these results.","42433410":"ID: 42433410\nTitle: Assessment of radionuclide levels, annual effective dose, and lifetime cancer risk from cultivated crop samples in Hainan Island, China.\nAbstract: This study aims to evaluate the activity concentrations of natural radionuclides in major edible crops from Hainan Island, quantify the annual effective dose and lifetime cancer risk (ELCR) caused by dietary intake, and provide a scientific basis for local food safety regulation and radiation protection strategies. Sixteen representative crop samples (12 vegetables, 4 grains) were collected in 2025. High-purity germanium gamma spectrometry (HPGe) was used to measure the activity concentrations of 228Ra, 226Ra, and 40K. Combined with Chinese dietary consumption data and ICRP-recommended dose conversion coefficients, the annual effective doses for adults and children were calculated, and ELCR was estimated using a risk model. Radionuclide activities followed the order 40K > 228Ra > 226Ra. The average 40K concentration was highest (vegetables: 121.517 (95% CI: 99.252-143.781) Bq/kg; grains: 146.375 (95% CI: -194.875-487.625) Bq/kg). 226Ra and 228Ra levels were below national regulatory limits. The mean annual effective doses from vegetable consumption were 0.116 (95% CI: 0.095-0.137) mSv/y for adults and 0.213 (95% CI: 0.169-0.257) mSv/y for children, grain consumption contributed 0.216 (95% CI: -0.304-0.736) mSv/y and 0.405 (95% CI: -0.593-1.403) mSv/y, respectively. Only one rice sample (G2) produced an annual effective dose for children (1.344 mSv/y) exceeding the 1 mSv/y reference level. ELCR was far below the ICRP recommended limit (2.5 × 10-3), with children's risk approximately 1.8 times higher than that of adults. The radioactivity levels in Hainan crops are generally safe, and the radiation risk from dietary intake is within acceptable limits. Children require particular attention due to differences in metabolism and consumption rates. Long-term monitoring is recommended, especially for staple crops like rice, and further research should track the impact of agricultural practices on radionuclide migration.","42433782":"ID: 42433782\nTitle: Dietary fatty acid intake and the risk of pancreatic cancer: a dose-response meta-analysis of observational studies.\nAbstract: The impact of fatty acids on pancreatic cancer (PC) risk remains contentious, prompting evaluation through current observational evidence. This systematic review and dose-response meta-analysis of observational studies aim to examine the association between dietary polyunsaturated fatty acids (PUFAs), monounsaturated fatty acids (MUFAs), saturated fatty acids (SFAs), trans fatty acids (TFAs), and the risk of PC. We systematically searched PubMed, Scopus, Cochrane, and Web of Science until December 2024. We included cohort and case-control studies that reported risk ratios (RRs), odds ratios (ORs), or hazard ratios (HRs) with 95% confidence intervals (CIs). The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the included studies. Overall, 26 observational studies (15 case-control and 11 cohort) showed no significant associations between TFA, MUFA, PUFA, or SFA intake and PC risk. However, case-control studies indicated a significant positive association for SFA intake (OR: 1.43; 95% CI: 1.02-1.99) and an inverse association for PUFA intake (OR: 0.74; 95% CI: 0.59-0.94). No significant relationship was found for TFA or MUFA intake in case-control studies. Stratification by study design was conducted to address differences in bias, such as recall bias in case-control studies and longer follow-up periods in cohort studies. Our findings suggest that modifying dietary fatty acid intake may contribute to PC prevention. These results highlight the need for further research to confirm these associations, explore underlying mechanisms, and examine the impact of dietary patterns and fatty acid sources on PC risk.","42434315":"ID: 42434315\nTitle: The Feasibility, Acceptability and Impact of a Remotely Delivered Whole-Food Plant-Based Education Program.\nAbstract: Chronic conditions linked to Western dietary patterns, together with the environmental impacts of high animal product consumption, highlight the need for scalable lifestyle medicine education strategies that support shifts toward plant-based eating. This pilot study examined the feasibility and acceptability of a 5-week, remotely delivered, nutrition-focused lifestyle medicine education program centered on whole-food plant-based eating, and examined changes in dietary intake, knowledge, skills, and perceptions. The pilot program comprised five weekly 90-minute interactive Zoom sessions covering whole-food plant-based principles, health and environmental considerations, and practical strategies for dietary change. Participants completed 24-hour dietary recalls using ASA24-AU and surveys assessing knowledge, skills, and perceptions at baseline and post-intervention. Nine women aged 20 to 61 years completed the pilot program. Acceptability was high (mean rating 4.07/5). Participants reported improvements in whole-food plant-based knowledge, greater confidence in food preparation, and more favorable perceptions of taste, satiety, and convenience. Significant reductions were observed in energy intake, cholesterol, sodium, selenium, vitamin B12, and percent energy from protein. A short-duration online whole-food plant-based education program was feasible, well accepted, and associated with measurable improvements in dietary behaviors and perceptions. Larger studies incorporating clinical outcomes and longer follow-up are warranted to assess long-term effectiveness and sustainability.","42434411":"ID: 42434411\nTitle: Dietary intake adequacy among Iranian older adults: evidence from national household survey data and two population-based cohorts.\nAbstract: Iran's aging population faces significant nutritional challenges. Comprehensive data on the dietary adequacy of older adults (OAs) using multiple sources are limited. This study assessed the adequacy of energy, macro- and micronutrient intake among Iranian OAs using data from the national household survey and two population-based cohorts. To comprehensively assess dietary intake patterns and nutrient adequacy among Iranian OAs, a multi-source analysis was conducted using: (1) the Iranian Household Expenditure and Income Survey (IHEIS, 2019-2022, n = 110,765 OAs) to estimate population-level intake via the Older Adult Male Equivalent (OAME) method; and (2) individual-level data from two cohorts, the Tehran Lipid and Glucose Study (TLGS, n = 1,839) and the Birjand Longitudinal Aging Study (BLAS, n = 1,325). Nutrient Adequacy Ratios (NAR) and Mean Adequacy Ratios (MAR) were calculated. Due to methodological differences, the datasets were analyzed separately, and the findings were interpreted in a complementary manner. IHEIS estimates revealed low intakes of fruits, vegetables, dairy, and meat, alongside a grain-dominant dietary pattern. Mean energy intake was below recommended levels and declined with age. Severe and persistent inadequacy was observed in the intake of several micronutrients, particularly vitamin D (NAR ≤ 0.04), vitamin A (NAR < 0.25), calcium (NAR 0.22-0.35), zinc (NAR 0.25-0.39), folate, and vitamin B12. MAR values ranged from 0.51 to 0.61, indicating that only about half of cumulative nutrient requirements were met, with consistently lower adequacy among women. Cohort data showed higher mean energy and nutrient intakes than those in IHEIS; however, substantial inter-individual variability was evident, and inadequacies in calcium, vitamin D, folate, and vitamin B12 persisted across cohorts. The diet of Iranian OAs is characterized by low dietary diversity, a high reliance on grains, and critical inadequacies in multiple micronutrients, with notable disparities by sex and age. Integrating adequacy-based indicators with multiple data sources provides a more accurate assessment of dietary vulnerability in older populations. The convergence of findings from household and individual-level data underscores an urgent need for targeted nutritional interventions to support healthy aging in Iran.","42434742":"ID: 42434742\nTitle: Integrative oncology in colorectal cancer: evidence-based strategies from prevention through survivorship.\nAbstract: Colorectal cancer (CRC) is a leading global malignancy, with approximately 1.9 million new cases and over 900,000 deaths recorded in 2022, yet evidence-based integrative oncology strategies remain inconsistently incorporated into routine care. This narrative review synthesizes current evidence across the full CRC care continuum, from primary prevention through long-term survivorship. High-fiber diets, Mediterranean dietary patterns, calcium supplementation, regular physical activity, healthy weight maintenance, and berberine each demonstrate reproducible CRC risk reduction in large prospective cohorts and multicenter randomized controlled trials. The CHALLENGE trial (NEJM 2025) provides the first randomized phase 3 evidence that structured exercise after adjuvant chemotherapy reduces disease recurrence (HR 0.72) and death (HR 0.63) in colon cancer. Aspirin chemoprevention requires individualized risk-benefit assessment per 2022 US Preventive Services Task Force guidelines; preliminary CaPP3 trial data (conference presentation, June 2025; not yet peer-reviewed) suggest non-inferiority of low-dose aspirin (75-100 mg/day) to 600 mg/day in Lynch syndrome, pending formal publication. Fusobacterium nucleatum promotes colorectal carcinogenesis through five mechanistically distinct pathways: FadA-mediated Wnt/β-catenin activation, Fap2- and CbpF-mediated immune evasion via TIGIT and CEACAM1, succinate-HIF-1α-EZH2-mediated immune suppression, Hippo pathway-mediated suppression of pyroptosis, and autophagy-induced chemoresistance. Perioperative multi-strain probiotics significantly reduce postoperative infectious complications, and fecal microbiota transplantation shows preliminary promise for sensitizing microsatellite-stable CRC to immunotherapy. The 2022-2024 SIO-ASCO and ASCO-SIO clinical practice guidelines endorse mindfulness-based interventions, yoga, and acupuncture for anxiety, depression, fatigue, and cancer-related pain. Systematic integration of these interventions into multidisciplinary CRC care requires standardized implementation frameworks, CRC-specific clinical trials for mind-body modalities, and bioavailability-optimized phytochemical formulations.","42435067":"ID: 42435067\nTitle: Correction: Trimester-specific associations of maternal prenatal dietary patterns with fetal growth: a prospective pre-birth cohort study.\nAbstract: ","42435080":"ID: 42435080\nTitle: Omnivorous and plant-based dietary patterns: a comparative analysis using data-driven and index-based approaches.\nAbstract: Plant-based diet (PBD) followers are growing worldwide. The aim was to explore the dietary profile of PBDs, taking the omnivorous (OMN) diet as a reference. A cross-sectional study was carried out. A total of 760 participants were included, of whom 161 self-identified as vegan, ovo-lacto-vegetarian, or pesco-vegetarian. Intakes of 175 foods, assessed through a food frequency questionnaire (FFQ), were adjusted for energy intake. The intake of 32 food groups was compared across diet types using Kruskal-Wallis and post-hoc tests. Adherence to established a priori dietary patterns (Pro-vegetarian, Mediterranean, and EAT-Lancet) diet was assessed. A posteriori dietary patterns were characterized using principal component analysis (PCA), k-means and hierarchical clustering, amongst others. Per 1000 kcal, daily mean intakes of legumes (> 48.2 g), vegetables/mushrooms (> 209.9 g), nuts (> 10.2 g), and whole grains (> 24.7 g) were higher in the PBD groups than OMN (p < 0.001). The three a priori dietary indices were inter-correlated (rho = 0.4-0.6) and OMN scored lower than the PBD groups (p < 0.001). PCA revealed a PBD-like pattern (variance: 15.0%), an unhealthy (7.2%), and a mixed animal-PBD pattern (5.5%). The clustering methods identified similar groupings of the PBD participants, and a group of PBD-like OMN (N = 61). The latter, compared with the other OMN patterns, showed significantly lower intakes of milk (48.0 vs. > 95.2 ml), red meat (13.9 vs. > 17.8 g), processed meat (9.0 vs. > 14.0 g), and precooked foods (9.0 vs. > 12.2 g), alongside higher intakes of whole grains (25.5 vs. < 20.8 g), nuts (13.8 vs. < 8.3 g), and vegetables (207.7 vs. < 161.3 g). Thus, food choices between OMN, vegetarians and vegans differ, beyond the exclusion of animal foods. PBDs present common characteristics despite their diversity, and some OMN share these dietary features.","42435090":"ID: 42435090\nTitle: Association between the traditional Chinese diet, non-communicable diseases and all-cause mortality: a longitudinal study based on China Health and Nutrition Survey (CHNS).\nAbstract: Traditional diets may reduce non-communicable disease (NCDs) risk. No research has examined associations between the traditional Chinese diet (TCD), defined using an a priori method, and NCD-related outcomes or all-cause mortality. This study aimed to assess the relationship between TCD adherence, NCD-related outcomes, and all-cause mortality. This longitudinal study utilised data from the China Health and Nutrition Survey (CHNS) between 1997 and 2011. Eligible participants were aged 18-74, had no NCDs at baseline, and participated in at least two survey waves. TCD adherence was assessed using a recently developed TCD index. Higher index scores indicate greater adherence; participants were categorised into low (0-6), medium (7-11), and high (12-23) adherence. Mixed-effects multilevel logistic regression and Cox proportional hazards models assessed associations with CVD, diabetes, cancer, obesity/central obesity, hypertension, and all-cause mortality. Among 11,158 participants (mean age 42.2 years, 51.3% women), high TCD adherence was associated with lower risk of CVD (OR: 0.73, 95% CI 0.61, 0.87) and all-cause mortality (HR: 0.73, 95% CI 0.63, 0.87), but higher risk of obesity (OR: 1.19, 95% CI 1.08, 1.32) and central obesity (OR: 1.19, 95% CI 1.12, 1.26). However, when standardising the energy intake on a common basis, TCD adherence was inversely associated with obesity and central obesity. Higher adherence to the TCD was associated with reduced risk of CVD and all-cause mortality in this sample of Chinese adults. The positive association with obesity highlights the need to consider total energy intake in future dietary recommendations.","42435109":"ID: 42435109\nTitle: Nutrigenetic Markers Related to Nutrient Metabolism, Recovery, and Performance in Athletes: a Review of Current Evidence.\nAbstract: This review aimed to evaluate current evidence regarding genetic markers associated with athletic performance, recovery, injury susceptibility, nutrient metabolism, responsiveness to ergogenic aids, and dietary behaviour in athletes. Classical candidate-gene studies and contemporary genome-wide investigations have identified numerous genetic variants associated with power and endurance performance, skeletal muscle capillarization, cardiac adaptation, energy metabolism, and injury susceptibility. Variants related to carbohydrate, fat, and branched-chain amino acid metabolism may contribute to inter-individual differences in substrate utilization and exercise responses. Genetic markers associated with iron, folate, and vitamin D metabolism, as well as variants influencing caffeine metabolism and sensitivity, are also relevant to sports nutrigenetics. However, differences in sample characteristics, ancestry, sport discipline, and exercise protocols limit the consistency and generalizability of the available findings. Athletic performance and nutritional responses are polygenic and multifactorial traits. Therefore, no single genetic variant should be considered an independent determinant of performance capacity or nutritional requirements. Genetic information should be interpreted together with dietary intake, biochemical indicators, training characteristics, clinical status, and individual tolerance. Current evidence remains insufficient to support the routine use of nutritional or supplementation strategies based solely on genotype.","42435783":"ID: 42435783\nTitle: CYP450 Network Shifts in MASLD/MASH: From Pathogenesis to Nutrition-Informed Modulation.\nAbstract: As MASLD/MASH becomes increasingly prevalent in parallel with obesity, metabolic dysfunction, and ultra-processed dietary patterns, understanding how diet-related exposures influence hepatic drug-metabolizing and lipid-metabolizing pathways has become clinically relevant. CYP450 enzymes represent a key interface between metabolic stress, xenobiotic handling, oxidative injury, and nutrition-related exposures, yet their role in MASLD/MASH has not been fully integrated from a nutrition-informed perspective. This review maps nutrition-exposure-CYP relationships across MASLD/MASH by integrating dietary patterns, food-processing exposures, contaminants/additives, and bioactive compounds within a structured qualitative framework. The reviewed evidence suggests that obesity, high-fat diet exposure, fructose co-exposure, and fatty acid composition may reshape hepatic CYP responses through isoform-, exposure-, and endpoint-dependent mechanisms. Human liver tissue and microsome studies provide relatively stronger translational evidence for altered CYP3A4 expression, activity, and clearance in NAFLD/NASH, whereas evidence for many nutrition-related exposures remains primarily animal-based, in vitro, or mechanistic. Macronutrient-related pathways, including fructose with high-fat intake and omega-6/omega-3 oxylipin imbalance, appear to influence CYP-mediated lipid and inflammatory signaling. Food-derived contaminants such as nitrosamines, aflatoxin B1, and acrylamide provide biologically plausible examples of CYP-dependent bioactivation in metabolically vulnerable liver contexts, although direct human MASLD/MASH validation remains limited. Evidence for food additives and phytochemicals is more preliminary and should be interpreted mainly as hypothesis-generating rather than clinically established. Across the reviewed evidence, metabolic inflammation appears to favor pro-oxidant CYP pathways, including CYP2E1 and CYP4A/4F, while suppressing or altering detoxification and epoxygenase-related pathways, including CYP3A and CYP2C/2J. However, changes in CYP expression do not necessarily translate into altered enzymatic activity or clinical clearance. We conclude that nutrition-related CYP remodeling may represent a mechanistic and translational interface linking diet, oxidative injury, xenobiotic handling, and MASLD/MASH progression. Future studies should integrate dietary exposure assessment with CYP activity or clearance phenotypes, oxidative stress biomarkers, gut-liver axis markers, and MASLD/MASH stage-specific clinical outcomes.","42435895":"ID: 42435895\nTitle: The association of dietary inflammation index (DII) and health-related outcomes: an umbrella review of systematic reviews.\nAbstract: Accumulating evidence suggests that adherence to pro-inflammatory dietary patterns, as reflected by elevated Dietary Inflammatory Index (DII) scores, is associated with adverse health outcomes. This umbrella review investigated the association between the DII and health-related outcomes. A comprehensive search was performed through PubMed, Scopus, Web of Science Core Collection and epistemonikos.org databases to identify related systematic reviews and/or meta-analyses published until July 2024. The identification of relevant studies, data extraction and critical appraisal of the included studies were performed independently by two investigators. The methodological quality was appraised using the Assessment of Multiple Systematic Reviews 2 (AMSTAR2) tool. The findings are presented using a narrative analysis. A total of 90 systematic reviews and/or meta-analyses were identified, evaluating associations between DII and various health outcomes: cancer (n = 32), mortality (n = 12), metabolic disorders (n = 8), cardiovascular diseases (CVDs) (n = 5), neurocognitive and mental health outcomes (n = 18), alterations in body composition (n = 6), bone disorders (n = 4), neurological disorders (n = 1), and pregnancy and maternal health outcomes (n = 3). Our findings suggest that high scores of DII have an adverse effect on various health outcomes compared to lower scores. However, the overall certainty of evidence is limited, as most included reviews were rated as having low or critically low methodological quality. The findings suggest that diets with high inflammatory load may represent a significant health risk factor, reinforcing the need for preventive interventions that promote anti-inflammatory dietary patterns. Future randomized controlled trials are warranted to confirm the potential benefits of anti-inflammatory diet patterns on health-related outcomes.

Perioperative dietary intake, such as a high-fat diet (HFD), has emerged as an essential regulator of postoperative pain sensitivity. While long-term HFD induces direct neuronal sensitization to prolong pain responses, the impact of short-term HFD on perioperative pain and its underlying mechanisms is yet to be characterized. Here, we investigated the role of short-term HFD intervention in postoperative pain using hindpaw incision (HPI) model in male mice. Pain behavioral tests showed that two weeks of HFD exposure significantly prolonged mechanical and thermal nociceptive responses in HPI compared to the normal diet. Mechanistically, short-term HFD disrupted lipid metabolic homeostasis, which dysregulated the local immune microenvironment. It shifted macrophage polarization from anti-inflammatory M2 to pro-inflammatory M1 phenotype and upregulated pro-nociceptive cytokines (e.g., TNF-α, IL-6) in the incised paw tissues. Notably, SerpinB6, a key mediator linking lipid metabolism to immune regulation, was downregulated by short-term HFD. Local restoration of SerpinB6 normalized macrophage polarization, reduced pro-inflammatory cytokines (IL-6, TNF-α), and alleviated pain hypersensitivity. Furthermore, SerpinB6 exerted its effect by restoring Sirt1 expression and attenuating ERK phosphorylation. Collectively, our findings revealed that short-term HFD primed acute postoperative pain via SerpinB6 protein downregulation and subsequent immune microenvironment dysregulation. This study highlighted that short-term dietary intervention and SerpinB6 as potential therapeutic strategies for perioperative pain management.","42436036":"ID: 42436036\nTitle: B Vitamins bioavailability in plant-based foods: Beyond content to nutritional impact.\nAbstract: B vitamins are essential water-soluble cofactors involved in metabolic regulation and neurological function. In plant-based diets, maintaining adequate B vitamin status is challenging because nutritional value depends not only on vitamin content but also on bioavailability. Although many plant foods contain substantial quantities of B vitamins, their absorption is generally lower than that from animal-derived sources due to differences in chemical form, matrix associations, and conjugation state. Thiamine and niacin often require liberation from bound forms; folates must undergo enzymatic deconjugation; vitamin B6 frequently occurs in glycosylated forms with reduced biological activity; and vitamin B12 is absent from unfortified plant foods. Bioavailability is further modulated by dietary composition, gastrointestinal conditions, and host genetic variability. Assessment approaches, such as in vitro models, cellular transport systems, and in vivo biomarkers, provide complementary but incomplete perspectives on physiological availability. Fermentation has emerged as a promising strategy to enhance B vitamin bioavailability in plant foods through microbial synthesis, matrix modification, and reduction of antinutritional factors. Applications in cereals, legumes, vegetables, and fruits demonstrate substantial improvements in vitamin content and accessibility. This chapter emphasizes the disconnect between analytical vitamin content and physiological impact and positions fermentation as a scalable approach to optimize B-vitamin nutrition in plant-based dietary patterns.","42436161":"ID: 42436161\nTitle: Dietary glucoraphenin ameliorates obesity and steatotic liver disease associated with gut dysbiosis induced by a Western diet in mice.\nAbstract: Western-style diets promote obesity, gut dysbiosis, and metabolic dysfunction-associated steatotic liver disease (MASLD). In this study, glucoraphenin (GRE), the major glucosinolate in radish (Raphanus sativus L.) greens and sprouts, was evaluated for its effects on Western diet (WD)-induced metabolic derangements and gut dysfunction in mice. Intaking of 1 mg/kg body weight of GRE with WD for 8 weeks caused significant reductions in adipogenesis indicators such as body weight gains, adipocyte hypertrophy, and serum leptin level. This result was further proved by significant changes in lipogenesis and lipolysis-related protein expressions in adipocyte. Administration of GRE also suppressed development of MASLD, which was observed through reductions in serum ALT and AST and suppressions the expression of FAS, SREBP1, mTOR, SCD1, ACC, and ChREBP in liver tissues. GRE administration effectively prevented the decrease in the gut microbial richness and diversity caused by WD and recovered serum branched-chain amino acids and microbiota-derived purine metabolites (inosine and hypoxanthine). These findings indicate that GRE mitigates WD-induced obesity and MASLD via coordinated regulation of lipid metabolism and the gut-liver axis.","42437199":"ID: 42437199\nTitle: A Nutrient Ratio-Based, Web-Enabled Food Quality Score Is Associated With Weight and Blood Pressure Compared With Leading Nutrient Profiling Systems.\nAbstract: Rising prevalence of chronic cardiometabolic conditions may be partly driven by shifts in dietary patterns. Nutrient profiling systems (NPSs) aim to guide healthier food choices through labeling and consumer-facing technologies but vary in accessibility and how well they distinguish food healthfulness. The primary objective was to compare a web-enabled, ratio-based NPS, Nutrient Consume Score (NCS), and its underlying nutrient ratios with 4 other leading NPSs, Nutri-Score, Health Star Rating, NOVA Classification, and Food Compass 2.0, by examining associations with obesity and blood pressure. Secondary objectives included assessing associations with cardiometabolic biomarkers and identifying food categories contributing most to each score. Cross-sectional study of NHANES 2015-2016 data from 9971 adults aged ≥20 y were analyzed. Dietary intake was assessed using a single 24-h dietary recall (day 1), and NPS scores were calculated. Multivariable regression models adjusted for sociodemographic and health factors examined associations with obesity, blood pressure, and cardiometabolic biomarkers. Compositional analysis evaluated food categories driving scores. Higher NCS was associated with lower BMI [β = -0.64 kg/m2 per 10-unit increase; 95% confidence interval (CI): -0.86, -0.41; P < 0.0001], waist circumference (β = -1.63 cm; 95% CI: -2.23, -1.02; P < 0.0001), systolic blood pressure (β = -1.01 mm Hg; 95% CI: -1.67, -0.35; P < 0.0051), and diastolic blood pressure (β = -0.56 mm Hg; 95% CI: -0.90, -0.23; P < 0.0026), with effect sizes comparable with other NPSs. Calorie-to-weight, sodium-to-potassium, and saturated-to-unsaturated fat ratios were associated with weight outcomes, whereas sodium-to-potassium and carbohydrate-to-fiber ratios were associated with blood pressure outcomes. The NCS was associated with weight and blood pressure in this cross-sectional analysis, with effect estimates comparable in magnitude with other commonly used NPSs. These findings support the potential utility of a ratio-based, web-enabled NPS for assessing diet quality in relation to cardiometabolic risk factors.","42437266":"ID: 42437266\nTitle: Global and regional inequalities in dairy recommendations: a natural language processing analysis of food-based dietary guidelines across income groups.\nAbstract: Food-based dietary guidelines (FBDGs) are key public health instruments aimed at promoting healthy dietary patterns. However, dairy-products recommendations vary substantially across countries, reflecting not only scientific evidence but also socioeconomic conditions, institutional capacity, and food system characteristics. The extent to which these differences are structured linguistically across income levels has not been systematically quantified. The present study aims to explore the use of advanced NLP techniques to characterize semantic differences and similarities in dairy-products dietary messages within FBDGs from countries with different levels of socioeconomic development. We conducted a comparative analysis of dairy-products recommendations extracted from national FBDGs officially recognised by the Food and Agriculture Organization, covering 98 countries. Using advanced natural language processing techniques, including lexical frequency analysis, co-occurrence networks, and latent topic modelling, we examined semantic patterns in recommendation statements and justificatory texts. Countries were stratified according to World Bank income group classifications. Across all income groups, \"milk\" emerged as the central lexical anchor of dairy recommendations. However, high-income countries demonstrated greater lexical diversity and semantic complexity, incorporating differentiated references to product types, fat content, and fermentation (e.g., yogurt, cheese, low-fat). In contrast, low- and lower-middle-income countries presented more general and nutritionally basic messaging, primarily focused on consumption adequacy and child nutrition. Justification texts consistently contained higher nutrient-related terminology density than recommendation statements. Dairy-products dietary messaging in national FBDGs shows consistent descriptive differences across income groups. These semantic disparities likely reflect contextual differences in institutional capacity, epidemiological priorities, and food system infrastructure. The findings may be particularly relevant for the Americas, where high-, upper-middle-, and lower-middle-income countries coexist within a region undergoing rapid nutrition transitions and facing the persistent triple burden of malnutrition. In this context, PAHO/WHO may play an important role in supporting greater harmonisation of dietary guidance across diverse socioeconomic settings. NLP-based approaches offer scalable tools for monitoring global nutrition policy discourse and supporting evidence-informed policy development.
