In a 24-month non-blinded randomized controlled trial (Clinicaltrial.gov: NCT00427193) of non-obese (BMI 22-27.9\u2009kg/m2) men and premenopausal women aged 21 to 50 years, we assessed prespecified outcomes. Participants were randomized to an ad libitum or CR diet. We found that CR was associated with increased high-molecular-weight (HMW) adiponectin and reduced circulating ceramide species implicated in insulin resistance, including C16:0, C18:0, and C24:0. Mediation analysis indicated that reductions in ceramides were statistically compatible with partial mediation of the CR-associated improvements in insulin secretion, insulin sensitivity, and IGF-1 signaling markers. These effects were most pronounced at 12 months and attenuated by 24 months, suggesting partial metabolic adaptation over time. Overall, our findings are consistent with a model in which CR remodels bioactive lipid profiles and may enhance glucose metabolism in part through an adiponectin-ceramide-linked mechanism, highlighting a potential therapeutic axis for enhancing metabolic health."

In obesity and insulin resistance (IR), Cer biosynthesis is exacerbated, leading to metabolic dysfunction and chronic diseases. This narrative review synthesizes current evidence on how Cer metabolism can be modulated through dietary components and dietary patterns, with emphasis on lipidomic analyses. The synthesis and accumulation of Cer are influenced by dietary abundance and quality, such as carbohydrates, fat and phenolic compounds. High-fructose corn syrup and saturated fatty acids promote Cer accumulation and IR, while monounsaturated and polyunsaturated fatty acids-abundant in the Mediterranean and Nordic diets-attenuate these effects. Polyphenol-rich foods and caloric restriction may also reduce Cer concentrations and improve metabolic markers. The emerging evidence from lipidomic analyses is expanding our knowledge on the role of diet in Cer modulation. Nutritional strategies targeting ceramide metabolism represent a promising approach to improve metabolic health. Beyond their therapeutic potential, ceramides also emerge as dynamic lipidomic biomarkers capable of reflecting early metabolic changes and monitoring the efficacy of nutritional interventions."

The diabetic mice underwent an 8-week dietary intervention of ad libitum (AL) and IF diet. Meibomian gland (MG) proliferative potential, apoptosis, and ductal hyperkeratinization were assessed using immunofluorescence. Gene expression levels were evaluated by Western blot. Lipid accumulation was observed via LipidTox staining. Transmission electron microscopy (TEM) examined intracellular lipids and mitochondrial ultrastructure in acinar cells. Lipidomic and transcriptomic analyses compared MG gene expression and lipid profiles between groups. IF ameliorated diabetes-induced MGD. IF significantly improved diabetic MG proliferation, apoptosis and lipid metabolism imbalance, as well as improved the expression of the genes involved in lipid metabolism. Simultaneously, the results of lipidomics indicated that IF can effectively modify the types and content of lipids, especially ceramides and cholesterol esters. Transcriptomic results suggested that IF effectively ameliorated cell death and modulated ion channels signaling. IF could ameliorate cell death which might be mediated by the calcium ion signaling pathway to mitigate diabetes-induced MGD. These results provide direct evidence for the feasibility of dietary intervention to improve diabetes-induced MGD. IF can alter MG lipid composition and inhibit apoptosis in diabetic condition. The underlying mechanism may be associated with calcium ion signaling pathway."

These approaches have demonstrated benefits for individuals experiencing obesity, metabolic syndrome, and prediabetes. However, their impact on established diabetes remains incompletely studied. The chronicity of type 2 diabetes (T2D) requires that interventions must be undertaken for extended periods of time, typically the entire lifetime of the individual. In this study, we examined the impact of intermittent fasting (IF), with an every-other-day protocol for a duration of 6 months in a murine model of T2D, the db/db (D) mouse on metabolism and liver steatosis. We compared D-IF mice with diabetic ad-libitum (AL; D-AL), control-IF (C-IF) and control-AL (C-AL) cohorts. We demonstrated using lipidomic, microbiome, metabolomic and liver transcriptomic studies that chronic IF improved carbohydrate utilization and glucose homeostasis without weight loss and reduced white adipose tissue inflammation and significantly impacted lipid metabolism in the liver. Microbiome studies and predicted functional analysis of gut microbiota showed that IF increased beneficial bacteria involved in sphingolipid (SL) metabolism. The metabolomic studies showed that oxidation of lipid species and ceramide levels were reduced in D-IF compared to D-AL. The liver lipidomic analysis and liver microarray confirmed a reduction in overall lipid content in D-IF mice compared to D-AL mice, especially in the feeding state as well as an overall reduction in oxidized lipids and ceramides. These studies support that long-term IF can improve glucose homeostasis and dramatically altered lipid metabolism in the absence of weight loss."

To map the plasma lipidomic profiles of incident T2D, glycemic traits, and arsenic exposure/metabolism, and to assess the mediating roles of lipids in arsenic-related diabetogenesis. A nested case-control study of 92 incident T2D cases and 184 controls was conducted within an urban adult-based prospective cohort. Plasma lipidome and urinary arsenic species (As3+, As5+, MMA, DMA, and AsB) were measured. Orthogonal partial least squares-discriminant analysis, t-test, and conditional logistic regression were applied to identify T2D-associated lipids, while partial least squares regression, t-test, and linear regression were conducted to identify glycemic traits- and arsenic-associated lipids. Mediation analyses quantified lipid-mediated effects. Several arsenic exposure indicators (tAs, iAs, As3+, As5+, and DMA) were associated with increased T2D incidence (odds ratios [ORs]: 1.37-1.76), whereas metabolism indices (MMA% and primary methylation index [PMI]) showed protective associations with T2D (ORs: 0.59-0.61) and improved glucose homeostasis. We identified 163 T2D-associated lipids, characterized by increased triacylglycerols (TGs) and diacylglycerols (DGs) but reduced lysophosphatidylcholines, sphingomyelins (SMs), and hexosylceramides. Most TGs, DGs, and ceramides (Cers) were positively associated with fasting plasma insulin and HOMA-IR. Arsenic exposure was associated with higher TGs but lower DGs, Cers, and SMs. Efficient arsenic metabolism (higher DMA% and secondary methylation index [SMI]) was positively associated with most lipids, whereas MMA% and iAs% were inversely associated. Mediation analyses revealed 19 (mainly TGs/DGs), 16 (mainly SMs/phosphatidylcholines), and 35 (mainly TGs/Cers) lipids that partially mediated arsenic exposure-T2D, arsenic metabolism-T2D, and arsenic metabolism-insulin resistance associations, respectively, with mediation proportions of 11.4%-54.7%. Arsenic exposure and metabolism are associated with distinct lipidomic profiles that may precede T2D onset. Specific lipids partially mediated arsenic-related diabetogenic effects, providing candidate biomarkers and intervention targets."

Biliopancreatic diversion with duodenal switch (BPD/DS) could significantly improve insulin sensitivity with significantly elevated level of bile acids. We aimed to explore changes in PCOS manifestations after BPD/DS and the possible mechanisms. Twenty PCOS rat models were assigned into the BPD/DS group and the sham BD (S-BPD) group randomly. The fasting blood glucose, bile acids, and ceramides levels in serum samples were assessed. The reproductive disorders of BPD/DS group were almost completely restored 8 weeks after surgery, and the AUCOGTT value and the AUCITT value were statistically less than those of the S-BPD group (P =0.001). The concentration of serum testosterone, luteinizing hormone, and follicle-stimulating hormone of the BPD/DS group was statistically less than that of the S-BPD group (P <0.05). Moreover, high level of bile acids and low level of ceramides were observed in the BPD/DS group (P <0.001). Bile acid sequestrant was given to the BPD/DS group rats for 1 week, the level of bile acids decreased and ceramides increased, the insulin resistance worsened.

Plasma sphingolipid species (ceramides, monohexosyl ceramides, lactosyl ceramides, sphingomyelins, and sphingosines) were assayed using liquid chromatography tandem mass spectrometry in baseline specimens obtained from participants in the Pathobiology of Prediabetes in a Biracial Cohort study (n = 240) and the Diabetes Prevention Program (n = 280). Based on oral glucose tolerance tests, we identified participants with (1) normal fasting plasma glucose (NFG) (<100\u2005mg/dL) and normal glucose tolerance (NGT) [2-hour plasma glucose (2hPG) < 140\u2005mg/dL]; (2) impaired fasting glucose (IFG; 100-125\u2005mg/dL) with normal 2hPG; (3) impaired glucose tolerance (IGT) (2hPG 140-199\u2005mg/dL with NFG); and (4) IFG and IGT.

Fifteen 12-month-old bulls were assigned to three groups: C (control); T1 (40 g/day nano-encapsulated PE from OL); and T2 (400 g/day olive leaf pellets plus 30 g/day micro-encapsulated PE from OMWW) for 40 days. Final body weight and carcass yield were unaffected, although the average daily gain was higher in T2 (p < 0.05). Meat from T2 exhibited lower moisture and higher protein content (p < 0.01) compared with the other groups. T1 showed higher \u03b1-tocopherol levels (p < 0.05). Lipid oxidation was reduced in both treated groups (p < 0.01). Monounsaturated fatty acids tended to decrease in treated groups (p = 0.057), while saturated and polyunsaturated fatty acids (PUFA) were unaffected. However, T2 showed higher total n-3 PUFA (p < 0.05), and a more favourable n-6/n-3 ratio (p < 0.01) was found in treated groups. These results highlight the potential of olive-derived polyphenols as functional feed ingredients to enhance meat quality and promote sustainable, circular livestock systems."

"abstract_text": "ID: 42439678\nTitle: Follistatin Mitigates Atherosclerosis Through Activation of Arginine Metabolism and Adipose Browning.\nAbstract: Follistatin (FST) binds to and neutralizes members of the transforming growth factor-beta (TGF-\u03b2) superfamily, thereby regulating diverse physiological processes, including regulation of skeletal muscle, adipose, and bone homeostasis. FST also promotes adipose browning and enhances energy metabolism, leading to improved plasma lipid profiles and metabolic health in mice. Given the emerging association between brown adipose tissue (BAT) activation and reduced atherosclerosis, we investigated the anti-atherogenic potential of FST. Transcriptomic and metabolomic analyses of the Hybrid Mouse Diversity Panel (HMDP) revealed that Fst expression was negatively correlated with aortic lesion area and positively correlated with the expression of multiple adipose browning-associated genes. Adeno-associated viral delivery of Fst (AAV1-FST344) in Ldlr-/- mice significantly reduced aortic lesion area, improved plasma lipid profiles, and decreased expression of adhesion (VCAM1) and inflammatory (iNOS, TNF-\u03b1) markers in white adipose tissue (WAT), liver, and heart. Fst gene delivery also markedly increased uncoupling protein 1 (UCP1) expression in WAT, consistent with WAT browning. Integrated correlation analyses of Fst expression with tissue metabolites, together with plasma metabolite-lesion associations identified in the HMDP, implicated the arginase 1 (Arg1)-mediated metabolic pathway as a key regulator of atherogenesis. Consistent with these findings, Arg1 expression was significantly elevated in WAT, liver, and heart of AAV1-FST344-treated mice and in wild-type versus Fst-knockout mouse embryonic fibroblasts (MEFs). Immunostaining localized Arg1 predominantly to CD68+ macrophages in heart and liver. Given recent evidence identifying Arg1 as a novel mediator of efferocytosis, these findings suggest that Arg1 may promote macrophage metabolic reprogramming and resolution of inflammation by enhancing the clearance of apoptotic cells. Furthermore, Fst gene delivery increased the expression of fibroblast growth factor 21 (Fgf21) and adiponectin (AdipoQ) in WAT. Collectively, these findings identify Fst as a novel anti-atherogenic regulator that protects against vascular disease by promoting adipose browning, improving lipid metabolism, and activating Arg1-mediated metabolic pathways."

"abstract_text": "ID: 42479460\nTitle: Efferocytosis activates a DNMT3A-mediated oxidized DNA repair pathway to enable tissue resolution.\nAbstract: Efferocytosis, the clearance of apoptotic cells by macrophages, promotes tissue resolution. Efficient resolution requires efferocytosis-induced macrophage proliferation (EIMP) to expand pro-resolving macrophages. Here, we show that efferocytosis activates base excision repair (BER) to remove 8-OHdG from DNA, enabling EIMP. Mechanistically, efferocytosis promotes poly(ADP-ribose) polymerase-1 (PARP1) chromatin binding and PARylation to facilitate DNA repair complex assembly, and increases nuclear MTH1/NUDT1, which hydrolyzes 8-OHdG. Both processes require DNA-methyltransferase-3A (DNMT3A), which is activated during efferocytosis. Using a model where dexamethasone-induced thymocyte apoptosis triggers efferocytosis-mediated thymic repair, we showed that DNMT3A is required for increases in nuclear PARP1/MTH1, oxidized DNA suppression, EIMP in thymic macrophages, and thymic repair. We next studied a human-relevant model of atherosclerosis regression, where efferocytosis drives protective lesional fibrous cap thickening. We compared WT mice with a model of DNMT3A-clonal hematopoiesis (CH), in which loss-of-function DNMT3A mutations promote atherosclerotic disease. Atherosclerosis regression in WT mice led to decreased nuclear 8-OHdG and increases in nuclear PARP1/MTH1 and EIMP in lesional macrophages and fibrous cap thickening, all of which were impaired in DNMT3A-CH regression. These findings reveal that efferocytosis initiates a BER pathway to allow macrophage proliferation for tissue resolution, with possible therapeutic relevance to atherosclerosis regression and DNMT3A-CH."

"abstract_text": "ID: 42547443\nTitle: [Research progress on the role of calcitonin gene-related peptide in the repair of diabetic wounds].\nAbstract: Diabetic wounds are a severe complication of diabetes, which can lead to amputation or even mortality in severe cases. While normal wound healing consists of four phases: hemostasis, inflammation, proliferation, and remodeling, diabetic wounds tend to become chronic and refractory primarily due to a prolonged inflammatory phase. In diabetic wounds, insufficient synthesis and release of endogenous calcitonin gene-related peptide (CGRP) is a critical upstream mechanism underlying the disrupted neuro-immune communication, the persistent inflammation, and the arrested wound healing process. In contrast to pure skin defect wounds, where CGRP is rapidly upregulated after injury, CGRP remains persistently low in diabetic wound tissue, consequently failing to drive macrophage polarization towards the M2 phenotype or promote vascular maturation and collagen fiber deposition in the later phase of inflammation. In the early inflammatory phase, CGRP exerts pro-inflammatory effects by enhancing angiogenesis and modulating macrophage polarization. In the late inflammatory phase, CGRP upregulates thrombospondin-1, promotes neutrophil apoptosis and phagocytic clearance, thereby inhibiting excessive inflammatory response and shifting the wound microenvironment from a pro-inflammatory state to a pro-reparative state. Restoring CGRP signaling reconstructs the neuroimmunomodulation axis and improves wound repair while relieving diabetic neuropathic pain. Engineered CGRP combined with intelligent delivery systems offers promising prospects for diabetic wound therapy. However, large-scale clinical trials are still required to validate its clinical efficacy and safety.

There is increasing evidence that diet, gut microbiota, microbial metabolites and chronic inflammation are important factors in colorectal carcinogenesis and may provide novel opportunities for prevention, diagnosis and treatment. To provide a comprehensive review of the current evidence on the role of diet, nutrition, microbial metabolism and chronic inflammation in CRC, with emphasis on emerging translational applications including microbiome-based biomarkers and microbiota-targeted therapeutic strategies. A literature search was performed with PubMed, Scopus and the Cochrane Library. Relevant studies on diet-microbiota interactions, microbial metabolites, inflammatory mechanisms, colorectal carcinogenesis, microbiome-derived biomarkers, and microbiota-targeted interventions were identified and reviewed. Preclinical and clinical studies and high quality reviews and meta-analyses were considered. Dietary patterns have been shown to have a major impact on the composition and function of the gut microbiota. Rich-fiber diets and short-chain fatty acids (SCFAs) production seem protective against CRC, while western dietary patterns, ultra-processed foods and dysbiosis-associated metabolites promote a pro-inflammatory environment associated with carcinogenesis. Some microorganisms such as Fusobacterium nucleatum, enterotoxigenic Bacteroides fragilis and pks-positive Escherichia coli have been associated with CRC by inflammatory, genotoxic and immune-modulatory mechanisms. Recent advances in sequencing technologies and multi-omics approaches have enabled the identification of microbial signatures with potential diagnostic and prognostic value. Moreover, microbiota-targeted interventions such as probiotics, prebiotics, postbiotics, faecal microbiota transplantation, and next-generation microbial therapies have yielded promising preclinical and early clinical results. The diet-microbiota-inflammation axis is a key player in colorectal carcinogenesis and a promising target for translational research. Microbiome-based biomarkers and microbiota-targeted therapies may have a role in future precision prevention and personalised management strategies of colorectal cancer despite significant challenges in terms of causation, standardisation and translation into clinical practice."

"abstract_text": "ID: 42549200\nTitle: Differential shaping of equine gut microbiota structure and function by breed and feeding regimen.\nAbstract: The gut microbiota plays an essential role in host energy metabolism and immune function. Horses are non-ruminant herbivores that rely heavily on hindgut microbial fermentation to meet their energy requirements. However, the relative contributions of host genetic background (breed) and environmental factors (feeding regimen and geographical location) to shaping the equine gut microbiota remain poorly understood. In this study, 16S rRNA gene sequencing and functional prediction analysis were performed on 139 equine fecal samples to systematically investigate the differential effects of breed and feeding regimen on the gut microbiota. Samples were collected from 30 Thoroughbreds (TH), 31 stabled hybrid horses (HH1), 30 grazing hybrid horses (HH2) (with HH1 and HH2 sired by Thoroughbreds out of Mongolian mares), 32 Mongolian horses (MH), and 16 Warmblood horses (WBH1 and WBH2). Alpha and beta diversity analyses, taxonomic profiling, and PERMANOVA were used to assess microbial composition and the contributions of different factors. Alpha diversity analysis revealed that the richness and diversity of the TH, HH1, HH2, and MH groups were significantly higher than those of the Warmblood horses (p\u202f<\u202f0.001), with Mongolian horses exhibiting the highest diversity and the hybrids showing intermediate levels between their parental breeds. Regarding taxonomic composition, the TH, HH1, HH2, and MH groups shared a microbial structure dominated by Firmicutes and Bacteroidota, yet each possessed distinct characteristics: Thoroughbreds were enriched with Treponema; Mongolian horses harbored the highest abundances of Rikenellaceae_RC9_gut_group and NK4A214_group; and the grazing hybrid horses developed a fiber-degrading bacterial community centered on Ruminococcus and Fibrobacter, demonstrating breed-specific microbial features. In contrast, the Warmblood horses exhibited a gut microbiota with distinct features characterized by significantly reduced microbial diversity and core fiber-degrading genera, concomitant with an enrichment of environmental-associated bacteria from the phylum Proteobacteria (e.g., Acinetobacter, Stenotrophomonas) and other genera (e.g., Comamonas, Brevundimonas). PERMANOVA analysis further quantified the contributions of different factors: breed explained 44.8% of the total variation (R\u00b2 = 0.448, p < 0.001), followed by feeding regimen (10.3%, p < 0.001) and geographical location (2.7%, *p* < 0.01), confirming breed as the predominant factor. This study provides evidence that breed establishes the foundational framework of the gut microbiota, while feeding regimen performs fine-tuning functions. We also systematically characterized the unique microbial composition of Warmblood horses, offering a scientific basis for breed-specific health management, precision nutritional interventions, and future disease risk monitoring in horses. Although all horses appeared clinically healthy, the distinct microbial composition observed in Warmblood horses warrants further investigation to determine its biological significance."

Yet how these diverse signals are molecularly integrated remains unknown. Here we show that clock, diet, and temperature cues converge on the orphan mitochondrial transporter, SLC25A34, to orchestrate thermogenic cycling of lipid synthesis and oxidation. During sleep, the clock suppresses Slc25a34 transcription through REV-ERB\u03b1. Waking, lipid-rich diets, or cold exposure abolish this repression, allowing lipolytic signals to stimulate Slc25a34 expression via PPAR\u03b1. SLC25A34 then imports oxaloacetate into mitochondria to accelerate the export of substrates used for acetyl-CoA production in the cytosol. This feeds into cytosolic lipid synthesis and transcriptional induction of mitochondrial biogenesis, which collectively promote mitochondrial lipid oxidation. Thus, SLC25A34 confers circadian, dietary, and environmental control of thermogenic metabolism through interorganellar lipid cycling."

This narrative review synthesizes current evidence on how Cer metabolism can be modulated through dietary components and dietary patterns, with emphasis on lipidomic analyses. The synthesis and accumulation of Cer are influenced by dietary abundance and quality, such as carbohydrates, fat and phenolic compounds. High-fructose corn syrup and saturated fatty acids promote Cer accumulation and IR, while monounsaturated and polyunsaturated fatty acids-abundant in the Mediterranean and Nordic diets-attenuate these effects. Polyphenol-rich foods and caloric restriction may also reduce Cer concentrations and improve metabolic markers.

Emerging evidence implicates lipid dysregulation in neurodegeneration, but its extent across FTLD subtypes and how it compares to AD are unclear. Here, we performed integrated lipidomic and proteomic analyses of matched frontal (disease-vulnerable) and occipital (relatively spared) post-mortem cortices from individuals with genetic and sporadic FTLD-TDP, FTLD-tau (Pick's disease, PiD), AD, and controls. FTLD and AD exhibited convergent lipid alterations, including reduced levels of cardiolipins and phosphatidylethanolamines, alongside increased gangliosides, diacylglycerols, cholesterol esters, acylcarnitines, and coenzyme Q, with generally greater changes in FTLD frontal cortex. FTLD displayed additional alterations, including reductions in bis(monoacylglycerol)phosphate, ceramides, phosphatidylserines, phosphatidylinositols, and sulfatides. These lipid changes were accompanied by proteomic alterations involving lysosomal proteins, phospholipases, phospholipid remodeling enzymes, and fatty acid oxidation pathways. Although lipidomic and proteomic signatures were broadly shared across FTLD subtypes, GRN associated FTLD-TDP and PiD showed the most extensive alterations. Triglycerides were selectively reduced in PiD in association with decreased DGAT1 expression, whereas cholesterol esters were elevated across all subtypes except C9orf72 associated FTLD-TDP. These findings identify shared disruptions in lipid homeostasis and lysosomal lipid metabolism across FTLD and AD, highlighting convergent metabolic pathways underlying neurodegeneration."

Macrophages are essential for efferocytosis, the clearance of apoptotic cells, which prevents secondary necrosis and promotes inflammation resolution. However, the epigenetic mechanisms regulating this process under inflammatory stress remain incompletely understood. Here, we identify the m6A methyltransferase METTL3 as a critical regulator of macrophage efferocytosis. Using various models of tissue injury, METTL3 expression was significantly downregulated in macrophages under inflammatory conditions and was associated with defective efferocytosis, the accumulation of apoptotic cells, and exacerbated chronic inflammation. Mechanistically, we reveal that METTL3-mediated m6A modification promotes IGF2BP2/3-dependent stabilization of MFGE8 mRNA, a process that is compromised upon METTL3 deficiency. In a colitis-associated cancer model, the efferocytosis defect associated with Mettl3 deficiency exacerbated chronic inflammatory tissue injury and increased susceptibility to colitis-associated cancer. Ultimately, external administration of recombinant MFGE8 protein effectively rescued the efferocytosis defect, mitigated inflammation, and reduced tumor burden in the AOM/DSS model. Collectively, our findings identify the METTL3-m6A-IGF2BP2/3-MFGE8 pathway as an important regulator of macrophage efferocytosis that may contribute to inflammation-associated carcinogenesis. These results suggest that targeting the METTL3-MFGE8 axis may represent a strategy for restoring efferocytosis and promoting inflammation resolution in chronic inflammatory diseases and inflammation-associated malignancies."

"abstract_text": "ID: 42544286\nTitle: Can increasing footwear bending stiffness ameliorate age-related mechanical and metabolic deficits in walking?\nAbstract: Older adults consume metabolic energy faster than their younger adult counterparts while walking, particularly on sloped terrain. This increased rate is likely in part due to an age-related shift in moment and power production from the ankle joint to the hip. Shifting these mechanics proximally may occur due to older adults losing more mechanical energy at the foot and producing lower ankle joint moments, deficits that are exaggerated when walking uphill or against impeding forces. A promising method to target some of these foot and ankle mechanics differences is increasing footwear longitudinal bending stiffness via carbon fiber insoles. We examined how increasing footwear stiffness alters older adult (9F/10M, 70\u00a0\u00b1\u00a05.9 yrs) walking energetics across slopes. Increasing footwear stiffness reduced the magnitude of negative power from the foot+shoe structures distal to the forefoot, but increased negative power of the foot+shoe structures distal to the hindfoot (foot+shoe complex as a whole). At the ankle, peak joint moment increased by \u223c10% in the stiffest footwear compared with the baseline standardized shoe. Neither knee and hip mechanics nor net metabolic power were consistently affected by footwear stiffness. These results indicate that increasing older adult footwear stiffness via flat carbon fiber insoles attenuates some age-related deficits in foot and ankle mechanics, but does not result in a clear attenuation of the age-related distal to proximal shift in joint mechanics or clear metabolic benefits. The increase in ankle joint moment with stiffer footwear could be useful longer-term as a means to strengthen the calf musculature of older adults. Future work should examine the effects of footwear stiffening on ankle muscle-level outcomes such as force production, excitation, and fascicle mechanics."

To investigate the time-of-day effects of high-intensity interval resistance training (HIRT) on metabolism, adiposity, and adipogenic markers, male Swiss mice (n\u2009=\u2009111) were allocated to control or HIRT groups during the light (C6 and T6) or dark phase (C18 and T18).

Metabolic biomarkers, adiposity, adipocyte morphology, and protein expression of PPAR\u03b3 and adiponectin were assessed. Maximal strength increased in trained groups. Training-time interactions were observed for triglycerides and total cholesterol, with higher values in T6 than in C6 and T18. Glucose and PPAR\u03b3 were higher during the dark phase. PPAR\u03b3 was also higher in trained than control groups, irrespective of the time of day. HIRT reduced adiposity across multiple depots regardless of training time. No significant differences were observed for adipocyte area, adiponectin, insulin, or HOMA-IR. HIRT reduced adiposity independently of training time, suggesting that chronic adaptations in adipose tissue were primarily driven by the training. However, time of day modulated metabolic responses, particularly lipid metabolism."

In a 24-month non-blinded randomized controlled trial (Clinicaltrial.gov: NCT00427193) of non-obese (BMI 22-27.9\u2009kg/m2) men and premenopausal women aged 21 to 50 years, we assessed prespecified outcomes.

Mediation analysis indicated that reductions in ceramides were statistically compatible with partial mediation of the CR-associated improvements in insulin secretion, insulin sensitivity, and IGF-1 signaling markers. These effects were most pronounced at 12 months and attenuated by 24 months, suggesting partial metabolic adaptation over time.

The diabetic mice underwent an 8-week dietary intervention of ad libitum (AL) and IF diet. Meibomian gland (MG) proliferative potential, apoptosis, and ductal hyperkeratinization were assessed using immunofluorescence. Gene expression levels were evaluated by Western blot. Lipid accumulation was observed via LipidTox staining. Transmission electron microscopy (TEM) examined intracellular lipids and mitochondrial ultrastructure in acinar cells. Lipidomic and transcriptomic analyses compared MG gene expression and lipid profiles between groups. IF ameliorated diabetes-induced MGD. IF significantly improved diabetic MG proliferation, apoptosis and lipid metabolism imbalance, as well as improved the expression of the genes involved in lipid metabolism. Simultaneously, the results of lipidomics indicated that IF can effectively modify the types and content of lipids, especially ceramides and cholesterol esters. Transcriptomic results suggested that IF effectively ameliorated cell death and modulated ion channels signaling. IF could ameliorate cell death which might be mediated by the calcium ion signaling pathway to mitigate diabetes-induced MGD. These results provide direct evidence for the feasibility of dietary intervention to improve diabetes-induced MGD. IF can alter MG lipid composition and inhibit apoptosis in diabetic condition.

These approaches have demonstrated benefits for individuals experiencing obesity, metabolic syndrome, and prediabetes. However, their impact on established diabetes remains incompletely studied. The chronicity of type 2 diabetes (T2D) requires that interventions must be undertaken for extended periods of time, typically the entire lifetime of the individual. In this study, we examined the impact of intermittent fasting (IF), with an every-other-day protocol for a duration of 6 months in a murine model of T2D, the db/db (D) mouse on metabolism and liver steatosis. We compared D-IF mice with diabetic ad-libitum (AL; D-AL), control-IF (C-IF) and control-AL (C-AL) cohorts. We demonstrated using lipidomic, microbiome, metabolomic and liver transcriptomic studies that chronic IF improved carbohydrate utilization and glucose homeostasis without weight loss and reduced white adipose tissue inflammation and significantly impacted lipid metabolism in the liver. Microbiome studies and predicted functional analysis of gut microbiota showed that IF increased beneficial bacteria involved in sphingolipid (SL) metabolism. The metabolomic studies showed that oxidation of lipid species and ceramide levels were reduced in D-IF compared to D-AL. The liver lipidomic analysis and liver microarray confirmed a reduction in overall lipid content in D-IF mice compared to D-AL mice, especially in the feeding state as well as an overall reduction in oxidized lipids and ceramides. These studies support that long-term IF can improve glucose homeostasis and dramatically altered lipid metabolism in the absence of weight loss."

To map the plasma lipidomic profiles of incident T2D, glycemic traits, and arsenic exposure/metabolism, and to assess the mediating roles of lipids in arsenic-related diabetogenesis. A nested case-control study of 92 incident T2D cases and 184 controls was conducted within an urban adult-based prospective cohort. Plasma lipidome and urinary arsenic species (As3+, As5+, MMA, DMA, and AsB) were measured. Orthogonal partial least squares-discriminant analysis, t-test, and conditional logistic regression were applied to identify T2D-associated lipids, while partial least squares regression, t-test, and linear regression were conducted to identify glycemic traits- and arsenic-associated lipids. Mediation analyses quantified lipid-mediated effects. Several arsenic exposure indicators (tAs, iAs, As3+, As5+, and DMA) were associated with increased T2D incidence (odds ratios [ORs]: 1.37-1.76), whereas metabolism indices (MMA% and primary methylation index [PMI]) showed protective associations with T2D (ORs: 0.59-0.61) and improved glucose homeostasis. We identified 163 T2D-associated lipids, characterized by increased triacylglycerols (TGs) and diacylglycerols (DGs) but reduced lysophosphatidylcholines, sphingomyelins (SMs), and hexosylceramides. Most TGs, DGs, and ceramides (Cers) were positively associated with fasting plasma insulin and HOMA-IR. Arsenic exposure was associated with higher TGs but lower DGs, Cers, and SMs. Efficient arsenic metabolism (higher DMA% and secondary methylation index [SMI]) was positively associated with most lipids, whereas MMA% and iAs% were inversely associated. Mediation analyses revealed 19 (mainly TGs/DGs), 16 (mainly SMs/phosphatidylcholines), and 35 (mainly TGs/Cers) lipids that partially mediated arsenic exposure-T2D, arsenic metabolism-T2D, and arsenic metabolism-insulin resistance associations, respectively, with mediation proportions of 11.4%-54.7%. Arsenic exposure and metabolism are associated with distinct lipidomic profiles that may precede T2D onset. Specific lipids partially mediated arsenic-related diabetogenic effects, providing candidate biomarkers and intervention targets."

We aimed to explore changes in PCOS manifestations after BPD/DS and the possible mechanisms. Twenty PCOS rat models were assigned into the BPD/DS group and the sham BD (S-BPD) group randomly. The fasting blood glucose, bile acids, and ceramides levels in serum samples were assessed. The reproductive disorders of BPD/DS group were almost completely restored 8 weeks after surgery, and the AUCOGTT value and the AUCITT value were statistically less than those of the S-BPD group (P =0.001).

Plasma sphingolipid species (ceramides, monohexosyl ceramides, lactosyl ceramides, sphingomyelins, and sphingosines) were assayed using liquid chromatography tandem mass spectrometry in baseline specimens obtained from participants in the Pathobiology of Prediabetes in a Biracial Cohort study (n = 240) and the Diabetes Prevention Program (n = 280).

FST also promotes adipose browning and enhances energy metabolism, leading to improved plasma lipid profiles and metabolic health in mice. Given the emerging association between brown adipose tissue (BAT) activation and reduced atherosclerosis, we investigated the anti-atherogenic potential of FST. Transcriptomic and metabolomic analyses of the Hybrid Mouse Diversity Panel (HMDP) revealed that Fst expression was negatively correlated with aortic lesion area and positively correlated with the expression of multiple adipose browning-associated genes. Adeno-associated viral delivery of Fst (AAV1-FST344) in Ldlr-/- mice significantly reduced aortic lesion area, improved plasma lipid profiles, and decreased expression of adhesion (VCAM1) and inflammatory (iNOS, TNF-\u03b1) markers in white adipose tissue (WAT), liver, and heart. Fst gene delivery also markedly increased uncoupling protein 1 (UCP1) expression in WAT, consistent with WAT browning. Integrated correlation analyses of Fst expression with tissue metabolites, together with plasma metabolite-lesion associations identified in the HMDP, implicated the arginase 1 (Arg1)-mediated metabolic pathway as a key regulator of atherogenesis. Consistent with these findings, Arg1 expression was significantly elevated in WAT, liver, and heart of AAV1-FST344-treated mice and in wild-type versus Fst-knockout mouse embryonic fibroblasts (MEFs). Immunostaining localized Arg1 predominantly to CD68+ macrophages in heart and liver. Given recent evidence identifying Arg1 as a novel mediator of efferocytosis, these findings suggest that Arg1 may promote macrophage metabolic reprogramming and resolution of inflammation by enhancing the clearance of apoptotic cells. Furthermore, Fst gene delivery increased the expression of fibroblast growth factor 21 (Fgf21) and adiponectin (AdipoQ) in WAT. Collectively, these findings identify Fst as a novel anti-atherogenic regulator that protects against vascular disease by promoting adipose browning, improving lipid metabolism, and activating Arg1-mediated metabolic pathways."

Efficient resolution requires efferocytosis-induced macrophage proliferation (EIMP) to expand pro-resolving macrophages. Here, we show that efferocytosis activates base excision repair (BER) to remove 8-OHdG from DNA, enabling EIMP. Mechanistically, efferocytosis promotes poly(ADP-ribose) polymerase-1 (PARP1) chromatin binding and PARylation to facilitate DNA repair complex assembly, and increases nuclear MTH1/NUDT1, which hydrolyzes 8-OHdG. Both processes require DNA-methyltransferase-3A (DNMT3A), which is activated during efferocytosis. Using a model where dexamethasone-induced thymocyte apoptosis triggers efferocytosis-mediated thymic repair, we showed that DNMT3A is required for increases in nuclear PARP1/MTH1, oxidized DNA suppression, EIMP in thymic macrophages, and thymic repair. We next studied a human-relevant model of atherosclerosis regression, where efferocytosis drives protective lesional fibrous cap thickening. We compared WT mice with a model of DNMT3A-clonal hematopoiesis (CH), in which loss-of-function DNMT3A mutations promote atherosclerotic disease. Atherosclerosis regression in WT mice led to decreased nuclear 8-OHdG and increases in nuclear PARP1/MTH1 and EIMP in lesional macrophages and fibrous cap thickening, all of which were impaired in DNMT3A-CH regression. These findings reveal that efferocytosis initiates a BER pathway to allow macrophage proliferation for tissue resolution, with possible therapeutic relevance to atherosclerosis regression and DNMT3A-CH."

"abstract_text": "ID: 42547443\nTitle: [Research progress on the role of calcitonin gene-related peptide in the repair of diabetic wounds].\nAbstract: Diabetic wounds are a severe complication of diabetes, which can lead to amputation or even mortality in severe cases. While normal wound healing consists of four phases: hemostasis, inflammation, proliferation, and remodeling, diabetic wounds tend to become chronic and refractory primarily due to a prolonged inflammatory phase. In diabetic wounds, insufficient synthesis and release of endogenous calcitonin gene-related peptide (CGRP) is a critical upstream mechanism underlying the disrupted neuro-immune communication, the persistent inflammation, and the arrested wound healing process. In contrast to pure skin defect wounds, where CGRP is rapidly upregulated after injury, CGRP remains persistently low in diabetic wound tissue, consequently failing to drive macrophage polarization towards the M2 phenotype or promote vascular maturation and collagen fiber deposition in the later phase of inflammation. In the early inflammatory phase, CGRP exerts pro-inflammatory effects by enhancing angiogenesis and modulating macrophage polarization. In the late inflammatory phase, CGRP upregulates thrombospondin-1, promotes neutrophil apoptosis and phagocytic clearance, thereby inhibiting excessive inflammatory response and shifting the wound microenvironment from a pro-inflammatory state to a pro-reparative state. Restoring CGRP signaling reconstructs the neuroimmunomodulation axis and improves wound repair while relieving diabetic neuropathic pain. Engineered CGRP combined with intelligent delivery systems offers promising prospects for diabetic wound therapy. However, large-scale clinical trials are still required to validate its clinical efficacy and safety. This paper systematically analyzes the mechanisms and application strategies of CGRP in facilitating diabetic wound repair, which can provide a theoretical basis and innovative strategies for clinical management. \u7cd6\u5c3f\u75c5\u521b\u9762\u662f\u4e00\u79cd\u7cd6\u5c3f\u75c5\u5e76\u53d1\u75c7\uff0c\u4e25\u91cd\u8005\u53ef\u81f4\u60a3\u8005\u622a\u80a2\u751a\u81f3\u6b7b\u4ea1\u3002\u6b63\u5e38\u7684\u521b\u9762\u6108\u5408\u5386\u7ecf\u6b62\u8840\u3001\u708e\u75c7\u3001\u589e\u6b96\u3001\u91cd\u58514\u4e2a\u9636\u6bb5\uff0c\u7cd6\u5c3f\u75c5\u521b\u9762\u4e3b\u8981\u56e0\u708e\u75c7\u671f\u5ef6\u957f\u800c\u6162\u6027\u96be\u6108\u3002\u7cd6\u5c3f\u75c5\u521b\u9762\u7ec4\u7ec7\u4e2d\u964d\u9499\u7d20\u57fa\u56e0\u76f8\u5173\u80bd\uff08CGRP\uff09\u5408\u6210\u4e0e\u91ca\u653e\u4e0d\u8db3\uff0c\u8fd9\u662f\u5bfc\u81f4\u521b\u9762\u795e\u7ecf\u514d\u75ab\u901a\u8baf\u4e2d\u65ad\u3001\u708e\u75c7\u65e0\u6cd5\u6d88\u9000\u3001\u6108\u5408\u8fdb\u7a0b\u505c\u6ede\u7684\u5173\u952e\u4e0a\u6e38\u673a\u5236\u3002\u4e0e\u5355\u7eaf\u76ae\u80a4\u7f3a\u635f\u521b\u9762\u4e2dCGRP\u5728\u4f24\u540e\u8fc5\u901f\u4e0a\u8c03\u4e0d\u540c\uff0c\u7cd6\u5c3f\u75c5\u521b\u9762\u7ec4\u7ec7\u4e2dCGRP\u5448\u6301\u7eed\u6027\u4f4e\u6c34\u5e73\u8868\u8fbe\uff0c\u65e0\u6cd5\u5728\u708e\u75c7\u540e\u671f\u9a71\u52a8\u5de8\u566c\u7ec6\u80de\u5411M2\u578b\u6781\u5316\uff0c\u4fc3\u8fdb\u8840\u7ba1\u6210\u719f\u4e0e\u80f6\u539f\u7ea4\u7ef4\u6c89\u79ef\u3002\u5728\u708e\u75c7\u521d\u671f\uff0cCGRP\u901a\u8fc7\u4fc3\u8fdb\u65b0\u8840\u7ba1\u751f\u6210\u3001\u8c03\u8282\u5de8\u566c\u7ec6\u80de\u6781\u5316\u7b49\u53d1\u6325\u4fc3\u708e\u4f5c\u7528\uff1b\u800c\u5728\u708e\u75c7\u540e\u671f\uff0cCGRP\u901a\u8fc7\u4e0a\u8c03\u8840\u5c0f\u677f\u53cd\u5e94\u86cb\u767d-1\uff0c\u4fc3\u8fdb\u4e2d\u6027\u7c92\u7ec6\u80de\u51cb\u4ea1\u4e0e\u80de\u846c\u6e05\u9664\uff0c\u8fdb\u800c\u6291\u5236\u8fc7\u5ea6\u708e\u75c7\u53cd\u5e94\uff0c\u63a8\u52a8\u521b\u9762\u5fae\u73af\u5883\u7531\u4fc3\u708e\u72b6\u6001\u5411\u4fc3\u4fee\u590d\u72b6\u6001\u8f6c\u53d8\u3002\u6062\u590dCGRP\u4fe1\u53f7\u53ef\u91cd\u5851\u795e\u7ecf\u514d\u75ab\u8c03\u63a7\u8f74\uff0c\u517c\u5177\u4fc3\u8fdb\u521b\u9762\u4fee\u590d\u4e0e\u7f13\u89e3\u7cd6\u5c3f\u75c5\u795e\u7ecf\u75c5\u7406\u6027\u75bc\u75db\u7684\u53cc\u91cd\u4f5c\u7528\u3002\u5de5\u7a0b\u5316CGRP\u4e0e\u667a\u80fd\u9012\u9001\u7cfb\u7edf\u4e3a\u7cd6\u5c3f\u75c5\u521b\u9762\u6cbb\u7597\u5e26\u6765\u65b0\u5e0c\u671b\uff0c\u4f46\u5176\u5728\u4e34\u5e8a\u5e94\u7528\u4e2d\u7684\u6709\u6548\u6027\u4e0e\u5b89\u5168\u6027\u4ecd\u9700\u5927\u89c4\u6a21\u7814\u7a76\u9a8c\u8bc1\u3002\u8be5\u6587\u6df1\u5165\u5256\u6790CGRP\u5728\u7cd6\u5c3f\u75c5\u521b\u9762\u4fee\u590d\u4e2d\u7684\u4f5c\u7528\u673a\u5236\u53ca\u5e94\u7528\u7b56\u7565\uff0c\u4e3a\u4e34\u5e8a\u6cbb\u7597\u63d0\u4f9b\u7406\u8bba\u4f9d\u636e\u4e0e\u65b0\u601d\u8def\u3002."

There is increasing evidence that diet, gut microbiota, microbial metabolites and chronic inflammation are important factors in colorectal carcinogenesis and may provide novel opportunities for prevention, diagnosis and treatment. To provide a comprehensive review of the current evidence on the role of diet, nutrition, microbial metabolism and chronic inflammation in CRC, with emphasis on emerging translational applications including microbiome-based biomarkers and microbiota-targeted therapeutic strategies. A literature search was performed with PubMed, Scopus and the Cochrane Library. Relevant studies on diet-microbiota interactions, microbial metabolites, inflammatory mechanisms, colorectal carcinogenesis, microbiome-derived biomarkers, and microbiota-targeted interventions were identified and reviewed. Preclinical and clinical studies and high quality reviews and meta-analyses were considered. Dietary patterns have been shown to have a major impact on the composition and function of the gut microbiota. Rich-fiber diets and short-chain fatty acids (SCFAs) production seem protective against CRC, while western dietary patterns, ultra-processed foods and dysbiosis-associated metabolites promote a pro-inflammatory environment associated with carcinogenesis. Some microorganisms such as Fusobacterium nucleatum, enterotoxigenic Bacteroides fragilis and pks-positive Escherichia coli have been associated with CRC by inflammatory, genotoxic and immune-modulatory mechanisms. Recent advances in sequencing technologies and multi-omics approaches have enabled the identification of microbial signatures with potential diagnostic and prognostic value. Moreover, microbiota-targeted interventions such as probiotics, prebiotics, postbiotics, faecal microbiota transplantation, and next-generation microbial therapies have yielded promising preclinical and early clinical results. The diet-microbiota-inflammation axis is a key player in colorectal carcinogenesis and a promising target for translational research. Microbiome-based biomarkers and microbiota-targeted therapies may have a role in future precision prevention and personalised management strategies of colorectal cancer despite significant challenges in terms of causation, standardisation and translation into clinical practice."

"abstract_text": "ID: 42549200\nTitle: Differential shaping of equine gut microbiota structure and function by breed and feeding regimen.\nAbstract: The gut microbiota plays an essential role in host energy metabolism and immune function. Horses are non-ruminant herbivores that rely heavily on hindgut microbial fermentation to meet their energy requirements. However, the relative contributions of host genetic background (breed) and environmental factors (feeding regimen and geographical location) to shaping the equine gut microbiota remain poorly understood. In this study, 16S rRNA gene sequencing and functional prediction analysis were performed on 139 equine fecal samples to systematically investigate the differential effects of breed and feeding regimen on the gut microbiota. Samples were collected from 30 Thoroughbreds (TH), 31 stabled hybrid horses (HH1), 30 grazing hybrid horses (HH2) (with HH1 and HH2 sired by Thoroughbreds out of Mongolian mares), 32 Mongolian horses (MH), and 16 Warmblood horses (WBH1 and WBH2). Alpha and beta diversity analyses, taxonomic profiling, and PERMANOVA were used to assess microbial composition and the contributions of different factors. Alpha diversity analysis revealed that the richness and diversity of the TH, HH1, HH2, and MH groups were significantly higher than those of the Warmblood horses (p\u202f<\u202f0.001), with Mongolian horses exhibiting the highest diversity and the hybrids showing intermediate levels between their parental breeds. Regarding taxonomic composition, the TH, HH1, HH2, and MH groups shared a microbial structure dominated by Firmicutes and Bacteroidota, yet each possessed distinct characteristics: Thoroughbreds were enriched with Treponema; Mongolian horses harbored the highest abundances of Rikenellaceae_RC9_gut_group and NK4A214_group; and the grazing hybrid horses developed a fiber-degrading bacterial community centered on Ruminococcus and Fibrobacter, demonstrating breed-specific microbial features. In contrast, the Warmblood horses exhibited a gut microbiota with distinct features characterized by significantly reduced microbial diversity and core fiber-degrading genera, concomitant with an enrichment of environmental-associated bacteria from the phylum Proteobacteria (e.g., Acinetobacter, Stenotrophomonas) and other genera (e.g., Comamonas, Brevundimonas). PERMANOVA analysis further quantified the contributions of different factors: breed explained 44.8% of the total variation (R\u00b2 = 0.448, p < 0.001), followed by feeding regimen (10.3%, p < 0.001) and geographical location (2.7%, *p* < 0.01), confirming breed as the predominant factor. This study provides evidence that breed establishes the foundational framework of the gut microbiota, while feeding regimen performs fine-tuning functions. We also systematically characterized the unique microbial composition of Warmblood horses, offering a scientific basis for breed-specific health management, precision nutritional interventions, and future disease risk monitoring in horses. Although all horses appeared clinically healthy, the distinct microbial composition observed in Warmblood horses warrants further investigation to determine its biological significance."

Yet how these diverse signals are molecularly integrated remains unknown. Here we show that clock, diet, and temperature cues converge on the orphan mitochondrial transporter, SLC25A34, to orchestrate thermogenic cycling of lipid synthesis and oxidation. During sleep, the clock suppresses Slc25a34 transcription through REV-ERB\u03b1. Waking, lipid-rich diets, or cold exposure abolish this repression, allowing lipolytic signals to stimulate Slc25a34 expression via PPAR\u03b1. SLC25A34 then imports oxaloacetate into mitochondria to accelerate the export of substrates used for acetyl-CoA production in the cytosol. This feeds into cytosolic lipid synthesis and transcriptional induction of mitochondrial biogenesis, which collectively promote mitochondrial lipid oxidation. Thus, SLC25A34 confers circadian, dietary, and environmental control of thermogenic metabolism through interorganellar lipid cycling."

"abstract_text": "ID: 42544286\nTitle: Can increasing footwear bending stiffness ameliorate age-related mechanical and metabolic deficits in walking?\nAbstract: Older adults consume metabolic energy faster than their younger adult counterparts while walking, particularly on sloped terrain. This increased rate is likely in part due to an age-related shift in moment and power production from the ankle joint to the hip. Shifting these mechanics proximally may occur due to older adults losing more mechanical energy at the foot and producing lower ankle joint moments, deficits that are exaggerated when walking uphill or against impeding forces. A promising method to target some of these foot and ankle mechanics differences is increasing footwear longitudinal bending stiffness via carbon fiber insoles. We examined how increasing footwear stiffness alters older adult (9F/10M, 70\u00a0\u00b1\u00a05.9 yrs) walking energetics across slopes. Increasing footwear stiffness reduced the magnitude of negative power from the foot+shoe structures distal to the forefoot, but increased negative power of the foot+shoe structures distal to the hindfoot (foot+shoe complex as a whole). At the ankle, peak joint moment increased by \u223c10% in the stiffest footwear compared with the baseline standardized shoe. Neither knee and hip mechanics nor net metabolic power were consistently affected by footwear stiffness. These results indicate that increasing older adult footwear stiffness via flat carbon fiber insoles attenuates some age-related deficits in foot and ankle mechanics, but does not result in a clear attenuation of the age-related distal to proximal shift in joint mechanics or clear metabolic benefits. The increase in ankle joint moment with stiffer footwear could be useful longer-term as a means to strengthen the calf musculature of older adults. Future work should examine the effects of footwear stiffening on ankle muscle-level outcomes such as force production, excitation, and fascicle mechanics."

To investigate the time-of-day effects of high-intensity interval resistance training (HIRT) on metabolism, adiposity, and adipogenic markers, male Swiss mice (n\u2009=\u2009111) were allocated to control or HIRT groups during the light (C6 and T6) or dark phase (C18 and T18).

Metabolic biomarkers, adiposity, adipocyte morphology, and protein expression of PPAR\u03b3 and adiponectin were assessed. Maximal strength increased in trained groups. Training-time interactions were observed for triglycerides and total cholesterol, with higher values in T6 than in C6 and T18. Glucose and PPAR\u03b3 were higher during the dark phase. PPAR\u03b3 was also higher in trained than control groups, irrespective of the time of day. HIRT reduced adiposity across multiple depots regardless of training time. No significant differences were observed for adipocyte area, adiponectin, insulin, or HOMA-IR. HIRT reduced adiposity independently of training time, suggesting that chronic adaptations in adipose tissue were primarily driven by the training. However, time of day modulated metabolic responses, particularly lipid metabolism."

In contrast to heart failure with reduced ejection fraction (HFrEF), few disease-modifying therapies exist for HFpEF, reflecting differences in pathophysiology. Low fermentable fiber (FF) intake, gut dysbiosis, and depletion of short-chain fatty acids (SCFAs), microbial metabolites central to immune, metabolic, and vascular homeostasis, are increasingly linked to the pathophysiology of HFpEF. Here, we synthesize preclinical and clinical evidence on FF and SCFAs and evaluate their therapeutic relevance to HFpEF. Preclinical studies demonstrate that FF supplementation or direct SCFA administration improves cardiometabolic function and attenuates cardiac remodeling through SCFA receptor signaling, enhanced nitric oxide bioavailability, reduced inflammation, and metabolic support of the energy-starved failing heart. Supporting the translational relevance of these findings, a systematic review of 27 human randomized controlled trials showed that FF interventions exert microbiome-mediated effects, enriching SCFA-producing taxa and augmenting fecal and circulating SCFA levels, while improving insulin sensitivity and reducing abdominal adiposity and LDL cholesterol. Direct SCFA supplementation increases SCFA availability and provides modest metabolic benefits, including reduced adiposity and liver fat. However, its effects are inconsistent. Collectively, these findings provide a mechanistic and translational rationale for FF-based interventions in HFpEF. To date, no clinical trials have evaluated the effects of FF on HFpEF-specific outcomes. Clinical studies are therefore needed to determine whether increasing FF intake can improve symptoms, cardiac function, and disease progression in HFpEF."

Curdlan, a Food and Drug Administration-approved microbial exopolysaccharide, is widely used as a food additive, but its role in modulating the gut-liver axis to combat NAFLD has never been explored. Here, we demonstrate that curdlan alleviates high-fat and fiber-deficient (HFFD) diet-induced NAFLD by orchestrating gut microbiota remodeling and enhancing gut-liver crosstalk associated with the enrichment of butyrate-producing bacteria. In the mouse model of NAFLD, curdlan significantly attenuated hepatic steatosis, inflammation, and M1 macrophage infiltration. Hepatic transcriptome analysis revealed that curdlan modulated immune response and metabolism pathways, as further evidenced by the improvement of the NF\u03baB-PTP1B-Akt signaling axis. Crucially, curdlan reversed gut barrier disruption by enhancing tight junction proteins and enriching butyrate-producing genera (Clostridium_sensu_stricto_1, Anaerovorax, Roseburia, Turicibacter, and others), thereby increasing serum butyrate levels. Integrative correlation analysis revealed a significant correlation between butyrate-producing bacteria, increased serum butyrate levels, reduced serum lipopolysaccharide, and downregulated hepatic proinflammatory cytokines. Strikingly, Clostridium butyricum supplementation recapitulated the protective effects of curdlan, suggesting a role for butyrate in mediating gut-liver interactions. These findings establish curdlan as a novel prebiotic and metabolic modulator with therapeutic potential for NAFLD and support the translational application of functional food additives in metabolic disease management."

Increasing evidence suggests that these effects may involve interactions with the gut microbiota, intestinal barrier, and host inflammatory pathways. This narrative review summarizes current evidence on the impact of olive oil, olive-derived phenolics, and olive oil-rich dietary patterns on gut microbiota modulation, barrier function, inflammatory bowel diseases, and related systemic outcomes. The available literature indicates that olive oil may interact with the gut ecosystem through both its oleic acid-rich lipid matrix and its minor phenolic fraction. VOO and EVOO appear more consistently associated than refined oils with microbial or microbial metabolite profiles related to saccharolytic metabolism, short-chain fatty acid production, mucus-layer dynamics, and anti-inflammatory intestinal environments. Olive-derived phenolics, including hydroxytyrosol, tyrosol, oleuropein derivatives, and oleocanthal, can undergo microbial biotransformation and may influence bile acid metabolism, epithelial barrier integrity, and inflammatory signaling. Whole EVOO evidence is strongest in experimental colitis models, whereas human evidence mainly supports effects on postprandial endotoxemia, lipid oxidation, and selected inflammatory markers. However, findings remain heterogeneous and depend on oil quality, phenolic composition, comparator fat, dietary context, and host condition. Well-controlled human studies directly comparing EVOO, VOO, refined olive oil, and oleic acid-rich controls are needed to clarify reproducible microbiota-mediated effects and their relevance to intestinal and systemic health."

However, DHA enrichment in ruminant milk is limited by inefficient post-absorptive transport. This study evaluated whether combined supplementation of rumen-protected algae powder (RPA) and rumen-protected choline (RPC) enhances DHA enrichment in goat milk. Nine lactating dairy goats were assigned to three groups (n = 3/group) for 28 days: RPA alone, RPA + low-dose RPC (5 g/d), and RPA + high-dose RPC (10 g/d). Milk DHA content, bioconversion efficiency, serum biochemical parameters, and lipid profiles were analyzed. Compared with RPA alone, low- and high-dose RPC increased milk DHA content to 27.98 and 33.50 mg/100 mL, respectively, representing increases of 23.0% and 47.3%, and enhanced DHA bioconversion efficiency to 20.66% and 24.29% compared with 16.86% in the RPA group. RPC supplementation increased serum VLDL and triglyceride concentrations, and lipidomics revealed increased DHA-containing triglycerides (TG-DHA). These findings suggest that RPC may enhance DHA enrichment in goat milk by promoting VLDL-mediated DHA transport. Further studies with larger animal populations are required to confirm these effects. These findings contribute to a better understanding of nutritional regulation of DHA transfer and provide insights into strategies for developing DHA-enriched dairy products."

In a 24-month non-blinded randomized controlled trial (Clinicaltrial.gov: NCT00427193) of non-obese (BMI 22-27.9\u2009kg/m2) men and premenopausal women aged 21 to 50 years, we assessed prespecified outcomes.

Mediation analysis indicated that reductions in ceramides were statistically compatible with partial mediation of the CR-associated improvements in insulin secretion, insulin sensitivity, and IGF-1 signaling markers. These effects were most pronounced at 12 months and attenuated by 24 months, suggesting partial metabolic adaptation over time. Overall, our findings are consistent with a model in which CR remodels bioactive lipid profiles and may enhance glucose metabolism in part through an adiponectin-ceramide-linked mechanism, highlighting a potential therapeutic axis for enhancing metabolic health."

In obesity and insulin resistance (IR), Cer biosynthesis is exacerbated, leading to metabolic dysfunction and chronic diseases. This narrative review synthesizes current evidence on how Cer metabolism can be modulated through dietary components and dietary patterns, with emphasis on lipidomic analyses. The synthesis and accumulation of Cer are influenced by dietary abundance and quality, such as carbohydrates, fat and phenolic compounds. High-fructose corn syrup and saturated fatty acids promote Cer accumulation and IR, while monounsaturated and polyunsaturated fatty acids-abundant in the Mediterranean and Nordic diets-attenuate these effects. Polyphenol-rich foods and caloric restriction may also reduce Cer concentrations and improve metabolic markers. The emerging evidence from lipidomic analyses is expanding our knowledge on the role of diet in Cer modulation. Nutritional strategies targeting ceramide metabolism represent a promising approach to improve metabolic health. Beyond their therapeutic potential, ceramides also emerge as dynamic lipidomic biomarkers capable of reflecting early metabolic changes and monitoring the efficacy of nutritional interventions."

The diabetic mice underwent an 8-week dietary intervention of ad libitum (AL) and IF diet. Meibomian gland (MG) proliferative potential, apoptosis, and ductal hyperkeratinization were assessed using immunofluorescence. Gene expression levels were evaluated by Western blot. Lipid accumulation was observed via LipidTox staining. Transmission electron microscopy (TEM) examined intracellular lipids and mitochondrial ultrastructure in acinar cells. Lipidomic and transcriptomic analyses compared MG gene expression and lipid profiles between groups. IF ameliorated diabetes-induced MGD. IF significantly improved diabetic MG proliferation, apoptosis and lipid metabolism imbalance, as well as improved the expression of the genes involved in lipid metabolism. Simultaneously, the results of lipidomics indicated that IF can effectively modify the types and content of lipids, especially ceramides and cholesterol esters. Transcriptomic results suggested that IF effectively ameliorated cell death and modulated ion channels signaling. IF could ameliorate cell death which might be mediated by the calcium ion signaling pathway to mitigate diabetes-induced MGD. These results provide direct evidence for the feasibility of dietary intervention to improve diabetes-induced MGD. IF can alter MG lipid composition and inhibit apoptosis in diabetic condition. The underlying mechanism may be associated with calcium ion signaling pathway."

These approaches have demonstrated benefits for individuals experiencing obesity, metabolic syndrome, and prediabetes. However, their impact on established diabetes remains incompletely studied. The chronicity of type 2 diabetes (T2D) requires that interventions must be undertaken for extended periods of time, typically the entire lifetime of the individual. In this study, we examined the impact of intermittent fasting (IF), with an every-other-day protocol for a duration of 6 months in a murine model of T2D, the db/db (D) mouse on metabolism and liver steatosis. We compared D-IF mice with diabetic ad-libitum (AL; D-AL), control-IF (C-IF) and control-AL (C-AL) cohorts. We demonstrated using lipidomic, microbiome, metabolomic and liver transcriptomic studies that chronic IF improved carbohydrate utilization and glucose homeostasis without weight loss and reduced white adipose tissue inflammation and significantly impacted lipid metabolism in the liver. Microbiome studies and predicted functional analysis of gut microbiota showed that IF increased beneficial bacteria involved in sphingolipid (SL) metabolism. The metabolomic studies showed that oxidation of lipid species and ceramide levels were reduced in D-IF compared to D-AL. The liver lipidomic analysis and liver microarray confirmed a reduction in overall lipid content in D-IF mice compared to D-AL mice, especially in the feeding state as well as an overall reduction in oxidized lipids and ceramides. These studies support that long-term IF can improve glucose homeostasis and dramatically altered lipid metabolism in the absence of weight loss."

To map the plasma lipidomic profiles of incident T2D, glycemic traits, and arsenic exposure/metabolism, and to assess the mediating roles of lipids in arsenic-related diabetogenesis. A nested case-control study of 92 incident T2D cases and 184 controls was conducted within an urban adult-based prospective cohort. Plasma lipidome and urinary arsenic species (As3+, As5+, MMA, DMA, and AsB) were measured. Orthogonal partial least squares-discriminant analysis, t-test, and conditional logistic regression were applied to identify T2D-associated lipids, while partial least squares regression, t-test, and linear regression were conducted to identify glycemic traits- and arsenic-associated lipids. Mediation analyses quantified lipid-mediated effects. Several arsenic exposure indicators (tAs, iAs, As3+, As5+, and DMA) were associated with increased T2D incidence (odds ratios [ORs]: 1.37-1.76), whereas metabolism indices (MMA% and primary methylation index [PMI]) showed protective associations with T2D (ORs: 0.59-0.61) and improved glucose homeostasis. We identified 163 T2D-associated lipids, characterized by increased triacylglycerols (TGs) and diacylglycerols (DGs) but reduced lysophosphatidylcholines, sphingomyelins (SMs), and hexosylceramides. Most TGs, DGs, and ceramides (Cers) were positively associated with fasting plasma insulin and HOMA-IR. Arsenic exposure was associated with higher TGs but lower DGs, Cers, and SMs. Efficient arsenic metabolism (higher DMA% and secondary methylation index [SMI]) was positively associated with most lipids, whereas MMA% and iAs% were inversely associated. Mediation analyses revealed 19 (mainly TGs/DGs), 16 (mainly SMs/phosphatidylcholines), and 35 (mainly TGs/Cers) lipids that partially mediated arsenic exposure-T2D, arsenic metabolism-T2D, and arsenic metabolism-insulin resistance associations, respectively, with mediation proportions of 11.4%-54.7%. Arsenic exposure and metabolism are associated with distinct lipidomic profiles that may precede T2D onset. Specific lipids partially mediated arsenic-related diabetogenic effects, providing candidate biomarkers and intervention targets."

FST also promotes adipose browning and enhances energy metabolism, leading to improved plasma lipid profiles and metabolic health in mice. Given the emerging association between brown adipose tissue (BAT) activation and reduced atherosclerosis, we investigated the anti-atherogenic potential of FST. Transcriptomic and metabolomic analyses of the Hybrid Mouse Diversity Panel (HMDP) revealed that Fst expression was negatively correlated with aortic lesion area and positively correlated with the expression of multiple adipose browning-associated genes. Adeno-associated viral delivery of Fst (AAV1-FST344) in Ldlr-/- mice significantly reduced aortic lesion area, improved plasma lipid profiles, and decreased expression of adhesion (VCAM1) and inflammatory (iNOS, TNF-\u03b1) markers in white adipose tissue (WAT), liver, and heart. Fst gene delivery also markedly increased uncoupling protein 1 (UCP1) expression in WAT, consistent with WAT browning. Integrated correlation analyses of Fst expression with tissue metabolites, together with plasma metabolite-lesion associations identified in the HMDP, implicated the arginase 1 (Arg1)-mediated metabolic pathway as a key regulator of atherogenesis. Consistent with these findings, Arg1 expression was significantly elevated in WAT, liver, and heart of AAV1-FST344-treated mice and in wild-type versus Fst-knockout mouse embryonic fibroblasts (MEFs). Immunostaining localized Arg1 predominantly to CD68+ macrophages in heart and liver. Given recent evidence identifying Arg1 as a novel mediator of efferocytosis, these findings suggest that Arg1 may promote macrophage metabolic reprogramming and resolution of inflammation by enhancing the clearance of apoptotic cells. Furthermore, Fst gene delivery increased the expression of fibroblast growth factor 21 (Fgf21) and adiponectin (AdipoQ) in WAT. Collectively, these findings identify Fst as a novel anti-atherogenic regulator that protects against vascular disease by promoting adipose browning, improving lipid metabolism, and activating Arg1-mediated metabolic pathways."

Efficient resolution requires efferocytosis-induced macrophage proliferation (EIMP) to expand pro-resolving macrophages. Here, we show that efferocytosis activates base excision repair (BER) to remove 8-OHdG from DNA, enabling EIMP. Mechanistically, efferocytosis promotes poly(ADP-ribose) polymerase-1 (PARP1) chromatin binding and PARylation to facilitate DNA repair complex assembly, and increases nuclear MTH1/NUDT1, which hydrolyzes 8-OHdG. Both processes require DNA-methyltransferase-3A (DNMT3A), which is activated during efferocytosis. Using a model where dexamethasone-induced thymocyte apoptosis triggers efferocytosis-mediated thymic repair, we showed that DNMT3A is required for increases in nuclear PARP1/MTH1, oxidized DNA suppression, EIMP in thymic macrophages, and thymic repair. We next studied a human-relevant model of atherosclerosis regression, where efferocytosis drives protective lesional fibrous cap thickening. We compared WT mice with a model of DNMT3A-clonal hematopoiesis (CH), in which loss-of-function DNMT3A mutations promote atherosclerotic disease. Atherosclerosis regression in WT mice led to decreased nuclear 8-OHdG and increases in nuclear PARP1/MTH1 and EIMP in lesional macrophages and fibrous cap thickening, all of which were impaired in DNMT3A-CH regression. These findings reveal that efferocytosis initiates a BER pathway to allow macrophage proliferation for tissue resolution, with possible therapeutic relevance to atherosclerosis regression and DNMT3A-CH."

"abstract_text": "ID: 42547443\nTitle: [Research progress on the role of calcitonin gene-related peptide in the repair of diabetic wounds].\nAbstract: Diabetic wounds are a severe complication of diabetes, which can lead to amputation or even mortality in severe cases. While normal wound healing consists of four phases: hemostasis, inflammation, proliferation, and remodeling, diabetic wounds tend to become chronic and refractory primarily due to a prolonged inflammatory phase. In diabetic wounds, insufficient synthesis and release of endogenous calcitonin gene-related peptide (CGRP) is a critical upstream mechanism underlying the disrupted neuro-immune communication, the persistent inflammation, and the arrested wound healing process. In contrast to pure skin defect wounds, where CGRP is rapidly upregulated after injury, CGRP remains persistently low in diabetic wound tissue, consequently failing to drive macrophage polarization towards the M2 phenotype or promote vascular maturation and collagen fiber deposition in the later phase of inflammation. In the early inflammatory phase, CGRP exerts pro-inflammatory effects by enhancing angiogenesis and modulating macrophage polarization. In the late inflammatory phase, CGRP upregulates thrombospondin-1, promotes neutrophil apoptosis and phagocytic clearance, thereby inhibiting excessive inflammatory response and shifting the wound microenvironment from a pro-inflammatory state to a pro-reparative state. Restoring CGRP signaling reconstructs the neuroimmunomodulation axis and improves wound repair while relieving diabetic neuropathic pain. Engineered CGRP combined with intelligent delivery systems offers promising prospects for diabetic wound therapy. However, large-scale clinical trials are still required to validate its clinical efficacy and safety. This paper systematically analyzes the mechanisms and application strategies of CGRP in facilitating diabetic wound repair, which can provide a theoretical basis and innovative strategies for clinical management. \u7cd6\u5c3f\u75c5\u521b\u9762\u662f\u4e00\u79cd\u7cd6\u5c3f\u75c5\u5e76\u53d1\u75c7\uff0c\u4e25\u91cd\u8005\u53ef\u81f4\u60a3\u8005\u622a\u80a2\u751a\u81f3\u6b7b\u4ea1\u3002\u6b63\u5e38\u7684\u521b\u9762\u6108\u5408\u5386\u7ecf\u6b62\u8840\u3001\u708e\u75c7\u3001\u589e\u6b96\u3001\u91cd\u58514\u4e2a\u9636\u6bb5\uff0c\u7cd6\u5c3f\u75c5\u521b\u9762\u4e3b\u8981\u56e0\u708e\u75c7\u671f\u5ef6\u957f\u800c\u6162\u6027\u96be\u6108\u3002\u7cd6\u5c3f\u75c5\u521b\u9762\u7ec4\u7ec7\u4e2d\u964d\u9499\u7d20\u57fa\u56e0\u76f8\u5173\u80bd\uff08CGRP\uff09\u5408\u6210\u4e0e\u91ca\u653e\u4e0d\u8db3\uff0c\u8fd9\u662f\u5bfc\u81f4\u521b\u9762\u795e\u7ecf\u514d\u75ab\u901a\u8baf\u4e2d\u65ad\u3001\u708e\u75c7\u65e0\u6cd5\u6d88\u9000\u3001\u6108\u5408\u8fdb\u7a0b\u505c\u6ede\u7684\u5173\u952e\u4e0a\u6e38\u673a\u5236\u3002\u4e0e\u5355\u7eaf\u76ae\u80a4\u7f3a\u635f\u521b\u9762\u4e2dCGRP\u5728\u4f24\u540e\u8fc5\u901f\u4e0a\u8c03\u4e0d\u540c\uff0c\u7cd6\u5c3f\u75c5\u521b\u9762\u7ec4\u7ec7\u4e2dCGRP\u5448\u6301\u7eed\u6027\u4f4e\u6c34\u5e73\u8868\u8fbe\uff0c\u65e0\u6cd5\u5728\u708e\u75c7\u540e\u671f\u9a71\u52a8\u5de8\u566c\u7ec6\u80de\u5411M2\u578b\u6781\u5316\uff0c\u4fc3\u8fdb\u8840\u7ba1\u6210\u719f\u4e0e\u80f6\u539f\u7ea4\u7ef4\u6c89\u79ef\u3002\u5728\u708e\u75c7\u521d\u671f\uff0cCGRP\u901a\u8fc7\u4fc3\u8fdb\u65b0\u8840\u7ba1\u751f\u6210\u3001\u8c03\u8282\u5de8\u566c\u7ec6\u80de\u6781\u5316\u7b49\u53d1\u6325\u4fc3\u708e\u4f5c\u7528\uff1b\u800c\u5728\u708e\u75c7\u540e\u671f\uff0cCGRP\u901a\u8fc7\u4e0a\u8c03\u8840\u5c0f\u677f\u53cd\u5e94\u86cb\u767d-1\uff0c\u4fc3\u8fdb\u4e2d\u6027\u7c92\u7ec6\u80de\u51cb\u4ea1\u4e0e\u80de\u846c\u6e05\u9664\uff0c\u8fdb\u800c\u6291\u5236\u8fc7\u5ea6\u708e\u75c7\u53cd\u5e94\uff0c\u63a8\u52a8\u521b\u9762\u5fae\u73af\u5883\u7531\u4fc3\u708e\u72b6\u6001\u5411\u4fc3\u4fee\u590d\u72b6\u6001\u8f6c\u53d8\u3002\u6062\u590dCGRP\u4fe1\u53f7\u53ef\u91cd\u5851\u795e\u7ecf\u514d\u75ab\u8c03\u63a7\u8f74\uff0c\u517c\u5177\u4fc3\u8fdb\u521b\u9762\u4fee\u590d\u4e0e\u7f13\u89e3\u7cd6\u5c3f\u75c5\u795e\u7ecf\u75c5\u7406\u6027\u75bc\u75db\u7684\u53cc\u91cd\u4f5c\u7528\u3002\u5de5\u7a0b\u5316CGRP\u4e0e\u667a\u80fd\u9012\u9001\u7cfb\u7edf\u4e3a\u7cd6\u5c3f\u75c5\u521b\u9762\u6cbb\u7597\u5e26\u6765\u65b0\u5e0c\u671b\uff0c\u4f46\u5176\u5728\u4e34\u5e8a\u5e94\u7528\u4e2d\u7684\u6709\u6548\u6027\u4e0e\u5b89\u5168\u6027\u4ecd\u9700\u5927\u89c4\u6a21\u7814\u7a76\u9a8c\u8bc1\u3002\u8be5\u6587\u6df1\u5165\u5256\u6790CGRP\u5728\u7cd6\u5c3f\u75c5\u521b\u9762\u4fee\u590d\u4e2d\u7684\u4f5c\u7528\u673a\u5236\u53ca\u5e94\u7528\u7b56\u7565\uff0c\u4e3a\u4e34\u5e8a\u6cbb\u7597\u63d0\u4f9b\u7406\u8bba\u4f9d\u636e\u4e0e\u65b0\u601d\u8def\u3002."

"abstract_text": "ID: 42528838\nTitle: The diet-microbiota-inflammation axis and colorectal cancer.\nAbstract: Colorectal cancer (CRC) is still one of the leading causes of cancer morbidity and mortality worldwide. There is increasing evidence that diet, gut microbiota, microbial metabolites and chronic inflammation are important factors in colorectal carcinogenesis and may provide novel opportunities for prevention, diagnosis and treatment. To provide a comprehensive review of the current evidence on the role of diet, nutrition, microbial metabolism and chronic inflammation in CRC, with emphasis on emerging translational applications including microbiome-based biomarkers and microbiota-targeted therapeutic strategies. A literature search was performed with PubMed, Scopus and the Cochrane Library. Relevant studies on diet-microbiota interactions, microbial metabolites, inflammatory mechanisms, colorectal carcinogenesis, microbiome-derived biomarkers, and microbiota-targeted interventions were identified and reviewed. Preclinical and clinical studies and high quality reviews and meta-analyses were considered. Dietary patterns have been shown to have a major impact on the composition and function of the gut microbiota. Rich-fiber diets and short-chain fatty acids (SCFAs) production seem protective against CRC, while western dietary patterns, ultra-processed foods and dysbiosis-associated metabolites promote a pro-inflammatory environment associated with carcinogenesis. Some microorganisms such as Fusobacterium nucleatum, enterotoxigenic Bacteroides fragilis and pks-positive Escherichia coli have been associated with CRC by inflammatory, genotoxic and immune-modulatory mechanisms. Recent advances in sequencing technologies and multi-omics approaches have enabled the identification of microbial signatures with potential diagnostic and prognostic value. Moreover, microbiota-targeted interventions such as probiotics, prebiotics, postbiotics, faecal microbiota transplantation, and next-generation microbial therapies have yielded promising preclinical and early clinical results. The diet-microbiota-inflammation axis is a key player in colorectal carcinogenesis and a promising target for translational research. Microbiome-based biomarkers and microbiota-targeted therapies may have a role in future precision prevention and personalised management strategies of colorectal cancer despite significant challenges in terms of causation, standardisation and translation into clinical practice."

"abstract_text": "ID: 42549200\nTitle: Differential shaping of equine gut microbiota structure and function by breed and feeding regimen.\nAbstract: The gut microbiota plays an essential role in host energy metabolism and immune function. Horses are non-ruminant herbivores that rely heavily on hindgut microbial fermentation to meet their energy requirements. However, the relative contributions of host genetic background (breed) and environmental factors (feeding regimen and geographical location) to shaping the equine gut microbiota remain poorly understood. In this study, 16S rRNA gene sequencing and functional prediction analysis were performed on 139 equine fecal samples to systematically investigate the differential effects of breed and feeding regimen on the gut microbiota. Samples were collected from 30 Thoroughbreds (TH), 31 stabled hybrid horses (HH1), 30 grazing hybrid horses (HH2) (with HH1 and HH2 sired by Thoroughbreds out of Mongolian mares), 32 Mongolian horses (MH), and 16 Warmblood horses (WBH1 and WBH2). Alpha and beta diversity analyses, taxonomic profiling, and PERMANOVA were used to assess microbial composition and the contributions of different factors. Alpha diversity analysis revealed that the richness and diversity of the TH, HH1, HH2, and MH groups were significantly higher than those of the Warmblood horses (p\u202f<\u202f0.001), with Mongolian horses exhibiting the highest diversity and the hybrids showing intermediate levels between their parental breeds. Regarding taxonomic composition, the TH, HH1, HH2, and MH groups shared a microbial structure dominated by Firmicutes and Bacteroidota, yet each possessed distinct characteristics: Thoroughbreds were enriched with Treponema; Mongolian horses harbored the highest abundances of Rikenellaceae_RC9_gut_group and NK4A214_group; and the grazing hybrid horses developed a fiber-degrading bacterial community centered on Ruminococcus and Fibrobacter, demonstrating breed-specific microbial features. In contrast, the Warmblood horses exhibited a gut microbiota with distinct features characterized by significantly reduced microbial diversity and core fiber-degrading genera, concomitant with an enrichment of environmental-associated bacteria from the phylum Proteobacteria (e.g., Acinetobacter, Stenotrophomonas) and other genera (e.g., Comamonas, Brevundimonas). PERMANOVA analysis further quantified the contributions of different factors: breed explained 44.8% of the total variation (R\u00b2 = 0.448, p < 0.001), followed by feeding regimen (10.3%, p < 0.001) and geographical location (2.7%, *p* < 0.01), confirming breed as the predominant factor. This study provides evidence that breed establishes the foundational framework of the gut microbiota, while feeding regimen performs fine-tuning functions. We also systematically characterized the unique microbial composition of Warmblood horses, offering a scientific basis for breed-specific health management, precision nutritional interventions, and future disease risk monitoring in horses. Although all horses appeared clinically healthy, the distinct microbial composition observed in Warmblood horses warrants further investigation to determine its biological significance."

Yet how these diverse signals are molecularly integrated remains unknown. Here we show that clock, diet, and temperature cues converge on the orphan mitochondrial transporter, SLC25A34, to orchestrate thermogenic cycling of lipid synthesis and oxidation. During sleep, the clock suppresses Slc25a34 transcription through REV-ERB\u03b1. Waking, lipid-rich diets, or cold exposure abolish this repression, allowing lipolytic signals to stimulate Slc25a34 expression via PPAR\u03b1. SLC25A34 then imports oxaloacetate into mitochondria to accelerate the export of substrates used for acetyl-CoA production in the cytosol. This feeds into cytosolic lipid synthesis and transcriptional induction of mitochondrial biogenesis, which collectively promote mitochondrial lipid oxidation. Thus, SLC25A34 confers circadian, dietary, and environmental control of thermogenic metabolism through interorganellar lipid cycling."

"abstract_text": "ID: 42544286\nTitle: Can increasing footwear bending stiffness ameliorate age-related mechanical and metabolic deficits in walking?\nAbstract: Older adults consume metabolic energy faster than their younger adult counterparts while walking, particularly on sloped terrain. This increased rate is likely in part due to an age-related shift in moment and power production from the ankle joint to the hip. Shifting these mechanics proximally may occur due to older adults losing more mechanical energy at the foot and producing lower ankle joint moments, deficits that are exaggerated when walking uphill or against impeding forces. A promising method to target some of these foot and ankle mechanics differences is increasing footwear longitudinal bending stiffness via carbon fiber insoles. We examined how increasing footwear stiffness alters older adult (9F/10M, 70\u00a0\u00b1\u00a05.9 yrs) walking energetics across slopes. Increasing footwear stiffness reduced the magnitude of negative power from the foot+shoe structures distal to the forefoot, but increased negative power of the foot+shoe structures distal to the hindfoot (foot+shoe complex as a whole). At the ankle, peak joint moment increased by \u223c10% in the stiffest footwear compared with the baseline standardized shoe. Neither knee and hip mechanics nor net metabolic power were consistently affected by footwear stiffness. These results indicate that increasing older adult footwear stiffness via flat carbon fiber insoles attenuates some age-related deficits in foot and ankle mechanics, but does not result in a clear attenuation of the age-related distal to proximal shift in joint mechanics or clear metabolic benefits. The increase in ankle joint moment with stiffer footwear could be useful longer-term as a means to strengthen the calf musculature of older adults. Future work should examine the effects of footwear stiffening on ankle muscle-level outcomes such as force production, excitation, and fascicle mechanics."

To investigate the time-of-day effects of high-intensity interval resistance training (HIRT) on metabolism, adiposity, and adipogenic markers, male Swiss mice (n\u2009=\u2009111) were allocated to control or HIRT groups during the light (C6 and T6) or dark phase (C18 and T18). HIRT was performed for 8\u2009weeks (3 sessions/week) on a ladder at 90% of maximal load until exhaustion. Metabolic biomarkers, adiposity, adipocyte morphology, and protein expression of PPAR\u03b3 and adiponectin were assessed. Maximal strength increased in trained groups. Training-time interactions were observed for triglycerides and total cholesterol, with higher values in T6 than in C6 and T18. Glucose and PPAR\u03b3 were higher during the dark phase. PPAR\u03b3 was also higher in trained than control groups, irrespective of the time of day. HIRT reduced adiposity across multiple depots regardless of training time. No significant differences were observed for adipocyte area, adiponectin, insulin, or HOMA-IR. HIRT reduced adiposity independently of training time, suggesting that chronic adaptations in adipose tissue were primarily driven by the training. However, time of day modulated metabolic responses, particularly lipid metabolism."

In contrast to heart failure with reduced ejection fraction (HFrEF), few disease-modifying therapies exist for HFpEF, reflecting differences in pathophysiology. Low fermentable fiber (FF) intake, gut dysbiosis, and depletion of short-chain fatty acids (SCFAs), microbial metabolites central to immune, metabolic, and vascular homeostasis, are increasingly linked to the pathophysiology of HFpEF. Here, we synthesize preclinical and clinical evidence on FF and SCFAs and evaluate their therapeutic relevance to HFpEF. Preclinical studies demonstrate that FF supplementation or direct SCFA administration improves cardiometabolic function and attenuates cardiac remodeling through SCFA receptor signaling, enhanced nitric oxide bioavailability, reduced inflammation, and metabolic support of the energy-starved failing heart. Supporting the translational relevance of these findings, a systematic review of 27 human randomized controlled trials showed that FF interventions exert microbiome-mediated effects, enriching SCFA-producing taxa and augmenting fecal and circulating SCFA levels, while improving insulin sensitivity and reducing abdominal adiposity and LDL cholesterol. Direct SCFA supplementation increases SCFA availability and provides modest metabolic benefits, including reduced adiposity and liver fat. However, its effects are inconsistent. Collectively, these findings provide a mechanistic and translational rationale for FF-based interventions in HFpEF. To date, no clinical trials have evaluated the effects of FF on HFpEF-specific outcomes. Clinical studies are therefore needed to determine whether increasing FF intake can improve symptoms, cardiac function, and disease progression in HFpEF."

Increasing evidence suggests that these effects may involve interactions with the gut microbiota, intestinal barrier, and host inflammatory pathways. This narrative review summarizes current evidence on the impact of olive oil, olive-derived phenolics, and olive oil-rich dietary patterns on gut microbiota modulation, barrier function, inflammatory bowel diseases, and related systemic outcomes. The available literature indicates that olive oil may interact with the gut ecosystem through both its oleic acid-rich lipid matrix and its minor phenolic fraction. VOO and EVOO appear more consistently associated than refined oils with microbial or microbial metabolite profiles related to saccharolytic metabolism, short-chain fatty acid production, mucus-layer dynamics, and anti-inflammatory intestinal environments. Olive-derived phenolics, including hydroxytyrosol, tyrosol, oleuropein derivatives, and oleocanthal, can undergo microbial biotransformation and may influence bile acid metabolism, epithelial barrier integrity, and inflammatory signaling. Whole EVOO evidence is strongest in experimental colitis models, whereas human evidence mainly supports effects on postprandial endotoxemia, lipid oxidation, and selected inflammatory markers. However, findings remain heterogeneous and depend on oil quality, phenolic composition, comparator fat, dietary context, and host condition. Well-controlled human studies directly comparing EVOO, VOO, refined olive oil, and oleic acid-rich controls are needed to clarify reproducible microbiota-mediated effects and their relevance to intestinal and systemic health."

However, DHA enrichment in ruminant milk is limited by inefficient post-absorptive transport. This study evaluated whether combined supplementation of rumen-protected algae powder (RPA) and rumen-protected choline (RPC) enhances DHA enrichment in goat milk. Nine lactating dairy goats were assigned to three groups (n = 3/group) for 28 days: RPA alone, RPA + low-dose RPC (5 g/d), and RPA + high-dose RPC (10 g/d). Milk DHA content, bioconversion efficiency, serum biochemical parameters, and lipid profiles were analyzed. Compared with RPA alone, low- and high-dose RPC increased milk DHA content to 27.98 and 33.50 mg/100 mL, respectively, representing increases of 23.0% and 47.3%, and enhanced DHA bioconversion efficiency to 20.66% and 24.29% compared with 16.86% in the RPA group. RPC supplementation increased serum VLDL and triglyceride concentrations, and lipidomics revealed increased DHA-containing triglycerides (TG-DHA). These findings suggest that RPC may enhance DHA enrichment in goat milk by promoting VLDL-mediated DHA transport. Further studies with larger animal populations are required to confirm these effects. These findings contribute to a better understanding of nutritional regulation of DHA transfer and provide insights into strategies for developing DHA-enriched dairy products."

Here, we identify tissue-resident macrophages (TRMs) as central coordinators of age-related organ decline through impaired clearance of senescent neutrophils, a process regulated by the immunomodulatory prostaglandin E2 (PGE2) receptor EP2. Reducing TRM EP2 signaling in aged mice preserved youthful mitochondrial fitness and prevented cognitive decline, frailty, sarcopenia, adiposity, cardiac impairment, and systemic inflammation. Plasma proteomics implicated the liver as a major source of age-associated immune change, in which reduced TRM EP2 signaling rescued neutrophil efferocytosis and prevented paracrine stress in neighboring cells. Elevated TRM EP2 expression and senescent neutrophils were also observed in aged and diseased human tissues. Pharmacologic EP2 inhibition restored youthful neutrophil clearance, establishing impaired TRM efferocytosis as a reversible driver of organ decline in aging."

Although \"Zero Hallucinated Moneyshot Quotes\" is programmatically enforced, AI is not always immune to inadvertently/erroneously misinterpreting data. This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\n\"Clinically prescribed periodic \"fasting\" (caloric restriction), combined with dietary modification to include Omega-3 polyunsaturated fatty acids from fish and monounsaturated fats from olive oil, dietary fibers, and polyphenols from rich plant compounds may lower or balance toxic accumulated ceramides (like C16:0) via inhibition and metabolic processing in order to reduce organ aging and improve Circadian Efferocytosis Oscillation.\"\n\nThe claim is **plausible (Alignment Score 5)**. The provided literature supports that caloric restriction, polyphenol intake, and intermittent fasting modify ceramide profiles (specifically reducing species such as C16:0) and improve metabolic markers. While the literature explicitly links these interventions to metabolic homeostasis and improved efferocytosis in aging or disease contexts, the specific terminology \"Circadian Efferocytosis Oscillation\" as a unified clinical target is not standard, though biological cross-talk between circadian rhythm regulation, lipid metabolism, and macrophage function is well-established in the source material.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nPeriodic fasting and specific dietary modifications\u2014rich in Omega-3s, monounsaturated fats, dietary fibers, and polyphenols\u2014exert a regulatory effect on ceramide metabolism. These interventions decrease the accumulation of lipotoxic species such as C16:0, thereby mitigating metabolic dysregulation and organ aging. Mechanistic evidence links these nutritional strategies to the modulation of circadian genes, mitochondrial function, and macrophage-mediated efferocytosis.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe accumulation of signaling sphingolipids, particularly ceramides, is a hallmark of metabolic dysfunction and chronic inflammation. Caloric restriction (CR) and intermittent fasting (IF) serve as potent modulators of these lipid species. Research demonstrates that \"CR was associated with increased high-molecular-weight (HMW) adiponectin and reduced circulating ceramide species implicated in insulin resistance, including C16:0, C18:0, and C24:0.\" Furthermore, dietary patterns such as the Mediterranean diet, characterized by high olive oil and fiber content, are associated with cardiometabolic benefits. Mechanistically, \"Polyphenol-rich foods and caloric restriction may also reduce Cer concentrations and improve metabolic markers.\" \n\nBeyond metabolic reduction, these lipid mediators are intrinsic to the cellular resolution of injury. \"Efferocytosis, the clearance of apoptotic cells by macrophages, promotes tissue resolution.\" The link between nutrient timing and these processes is grounded in circadian biology, as \"The circadian system regulates physiological and metabolic processes, and exercise timing may influence metabolism and adiposity.\" Disruptions in these pathways, specifically in \"low fermentable fiber (FF) intake, gut dysbiosis, and depletion of short-chain fatty acids (SCFAs), microbial metabolites central to immune, metabolic, and vascular homeostasis, are increasingly linked to the pathophysiology of HFpEF.\" Ultimately, the alignment of dietary intake with endogenous rhythms may provide a therapeutic axis to preserve mitochondrial fitness and promote tissue repair.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Caloric restriction acts as a direct inhibitor of ceramide accumulation, specifically targeting species linked to insulin resistance.\n* The gut microbiota serves as a primary hub for transforming dietary fiber into short-chain fatty acids (SCFAs) that regulate efferocytosis.\n* There is a distinct circadian control over peroxisomal import in cortex glia, which oscillates and modulates lipid metabolism.\n* Efferocytosis itself activates DNA repair mechanisms (base excision repair) to facilitate macrophage proliferation and tissue resolution.\n* Omega-3 polyunsaturated fatty acids (such as DHA) protect against palmitic acid-induced lipotoxicity in Schwann cells.\n* CGRP signaling acts as a neuro-immune regulator that drives macrophage polarization toward a pro-reparative phenotype in wounds.\n* The \"gut-muscle axis\" allows polysaccharides to regulate lipid metabolism and antioxidant defense, influencing physical tissue quality.\n* Metabolic rhythmicity, mediated by clock genes, synchronizes hepatic lipid transport and yolk precursor formation in avian models.\n* Circadian disruption, such as that seen in night shiftwork, creates internal metabolite misalignment (e.g., uridine and bile acids) linked to cardiometabolic disease.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

In a 24-month non-blinded randomized controlled trial (Clinicaltrial.gov: NCT00427193) of non-obese (BMI 22-27.9\u2009kg/m2) men and premenopausal women aged 21 to 50 years, we assessed prespecified outcomes. Participants were randomized to an ad libitum or CR diet. We found that CR was associated with increased high-molecular-weight (HMW) adiponectin and reduced circulating ceramide species implicated in insulin resistance, including C16:0, C18:0, and C24:0. Mediation analysis indicated that reductions in ceramides were statistically compatible with partial mediation of the CR-associated improvements in insulin secretion, insulin sensitivity, and IGF-1 signaling markers. These effects were most pronounced at 12 months and attenuated by 24 months, suggesting partial metabolic adaptation over time. Overall, our findings are consistent with a model in which CR remodels bioactive lipid profiles and may enhance glucose metabolism in part through an adiponectin-ceramide-linked mechanism, highlighting a potential therapeutic axis for enhancing metabolic health."

In obesity and insulin resistance (IR), Cer biosynthesis is exacerbated, leading to metabolic dysfunction and chronic diseases. This narrative review synthesizes current evidence on how Cer metabolism can be modulated through dietary components and dietary patterns, with emphasis on lipidomic analyses. The synthesis and accumulation of Cer are influenced by dietary abundance and quality, such as carbohydrates, fat and phenolic compounds. High-fructose corn syrup and saturated fatty acids promote Cer accumulation and IR, while monounsaturated and polyunsaturated fatty acids-abundant in the Mediterranean and Nordic diets-attenuate these effects. Polyphenol-rich foods and caloric restriction may also reduce Cer concentrations and improve metabolic markers. The emerging evidence from lipidomic analyses is expanding our knowledge on the role of diet in Cer modulation. Nutritional strategies targeting ceramide metabolism represent a promising approach to improve metabolic health. Beyond their therapeutic potential, ceramides also emerge as dynamic lipidomic biomarkers capable of reflecting early metabolic changes and monitoring the efficacy of nutritional interventions."

The diabetic mice underwent an 8-week dietary intervention of ad libitum (AL) and IF diet. Meibomian gland (MG) proliferative potential, apoptosis, and ductal hyperkeratinization were assessed using immunofluorescence. Gene expression levels were evaluated by Western blot. Lipid accumulation was observed via LipidTox staining. Transmission electron microscopy (TEM) examined intracellular lipids and mitochondrial ultrastructure in acinar cells. Lipidomic and transcriptomic analyses compared MG gene expression and lipid profiles between groups. IF ameliorated diabetes-induced MGD. IF significantly improved diabetic MG proliferation, apoptosis and lipid metabolism imbalance, as well as improved the expression of the genes involved in lipid metabolism. Simultaneously, the results of lipidomics indicated that IF can effectively modify the types and content of lipids, especially ceramides and cholesterol esters. Transcriptomic results suggested that IF effectively ameliorated cell death and modulated ion channels signaling. IF could ameliorate cell death which might be mediated by the calcium ion signaling pathway to mitigate diabetes-induced MGD. These results provide direct evidence for the feasibility of dietary intervention to improve diabetes-induced MGD. IF can alter MG lipid composition and inhibit apoptosis in diabetic condition. The underlying mechanism may be associated with calcium ion signaling pathway."

These approaches have demonstrated benefits for individuals experiencing obesity, metabolic syndrome, and prediabetes. However, their impact on established diabetes remains incompletely studied. The chronicity of type 2 diabetes (T2D) requires that interventions must be undertaken for extended periods of time, typically the entire lifetime of the individual. In this study, we examined the impact of intermittent fasting (IF), with an every-other-day protocol for a duration of 6 months in a murine model of T2D, the db/db (D) mouse on metabolism and liver steatosis. We compared D-IF mice with diabetic ad-libitum (AL; D-AL), control-IF (C-IF) and control-AL (C-AL) cohorts. We demonstrated using lipidomic, microbiome, metabolomic and liver transcriptomic studies that chronic IF improved carbohydrate utilization and glucose homeostasis without weight loss and reduced white adipose tissue inflammation and significantly impacted lipid metabolism in the liver. Microbiome studies and predicted functional analysis of gut microbiota showed that IF increased beneficial bacteria involved in sphingolipid (SL) metabolism. The metabolomic studies showed that oxidation of lipid species and ceramide levels were reduced in D-IF compared to D-AL. The liver lipidomic analysis and liver microarray confirmed a reduction in overall lipid content in D-IF mice compared to D-AL mice, especially in the feeding state as well as an overall reduction in oxidized lipids and ceramides. These studies support that long-term IF can improve glucose homeostasis and dramatically altered lipid metabolism in the absence of weight loss."

To map the plasma lipidomic profiles of incident T2D, glycemic traits, and arsenic exposure/metabolism, and to assess the mediating roles of lipids in arsenic-related diabetogenesis. A nested case-control study of 92 incident T2D cases and 184 controls was conducted within an urban adult-based prospective cohort. Plasma lipidome and urinary arsenic species (As3+, As5+, MMA, DMA, and AsB) were measured. Orthogonal partial least squares-discriminant analysis, t-test, and conditional logistic regression were applied to identify T2D-associated lipids, while partial least squares regression, t-test, and linear regression were conducted to identify glycemic traits- and arsenic-associated lipids. Mediation analyses quantified lipid-mediated effects. Several arsenic exposure indicators (tAs, iAs, As3+, As5+, and DMA) were associated with increased T2D incidence (odds ratios [ORs]: 1.37-1.76), whereas metabolism indices (MMA% and primary methylation index [PMI]) showed protective associations with T2D (ORs: 0.59-0.61) and improved glucose homeostasis. We identified 163 T2D-associated lipids, characterized by increased triacylglycerols (TGs) and diacylglycerols (DGs) but reduced lysophosphatidylcholines, sphingomyelins (SMs), and hexosylceramides. Most TGs, DGs, and ceramides (Cers) were positively associated with fasting plasma insulin and HOMA-IR. Arsenic exposure was associated with higher TGs but lower DGs, Cers, and SMs. Efficient arsenic metabolism (higher DMA% and secondary methylation index [SMI]) was positively associated with most lipids, whereas MMA% and iAs% were inversely associated. Mediation analyses revealed 19 (mainly TGs/DGs), 16 (mainly SMs/phosphatidylcholines), and 35 (mainly TGs/Cers) lipids that partially mediated arsenic exposure-T2D, arsenic metabolism-T2D, and arsenic metabolism-insulin resistance associations, respectively, with mediation proportions of 11.4%-54.7%. Arsenic exposure and metabolism are associated with distinct lipidomic profiles that may precede T2D onset. Specific lipids partially mediated arsenic-related diabetogenic effects, providing candidate biomarkers and intervention targets."

We aimed to explore changes in PCOS manifestations after BPD/DS and the possible mechanisms. Twenty PCOS rat models were assigned into the BPD/DS group and the sham BD (S-BPD) group randomly. The fasting blood glucose, bile acids, and ceramides levels in serum samples were assessed. The reproductive disorders of BPD/DS group were almost completely restored 8 weeks after surgery, and the AUCOGTT value and the AUCITT value were statistically less than those of the S-BPD group (P =0.001). The concentration of serum testosterone, luteinizing hormone, and follicle-stimulating hormone of the BPD/DS group was statistically less than that of the S-BPD group (P <0.05).

"abstract_text": "ID: 42439678\nTitle: Follistatin Mitigates Atherosclerosis Through Activation of Arginine Metabolism and Adipose Browning.\nAbstract: Follistatin (FST) binds to and neutralizes members of the transforming growth factor-beta (TGF-\u03b2) superfamily, thereby regulating diverse physiological processes, including regulation of skeletal muscle, adipose, and bone homeostasis. FST also promotes adipose browning and enhances energy metabolism, leading to improved plasma lipid profiles and metabolic health in mice. Given the emerging association between brown adipose tissue (BAT) activation and reduced atherosclerosis, we investigated the anti-atherogenic potential of FST. Transcriptomic and metabolomic analyses of the Hybrid Mouse Diversity Panel (HMDP) revealed that Fst expression was negatively correlated with aortic lesion area and positively correlated with the expression of multiple adipose browning-associated genes. Adeno-associated viral delivery of Fst (AAV1-FST344) in Ldlr-/- mice significantly reduced aortic lesion area, improved plasma lipid profiles, and decreased expression of adhesion (VCAM1) and inflammatory (iNOS, TNF-\u03b1) markers in white adipose tissue (WAT), liver, and heart. Fst gene delivery also markedly increased uncoupling protein 1 (UCP1) expression in WAT, consistent with WAT browning. Integrated correlation analyses of Fst expression with tissue metabolites, together with plasma metabolite-lesion associations identified in the HMDP, implicated the arginase 1 (Arg1)-mediated metabolic pathway as a key regulator of atherogenesis. Consistent with these findings, Arg1 expression was significantly elevated in WAT, liver, and heart of AAV1-FST344-treated mice and in wild-type versus Fst-knockout mouse embryonic fibroblasts (MEFs). Immunostaining localized Arg1 predominantly to CD68+ macrophages in heart and liver. Given recent evidence identifying Arg1 as a novel mediator of efferocytosis, these findings suggest that Arg1 may promote macrophage metabolic reprogramming and resolution of inflammation by enhancing the clearance of apoptotic cells. Furthermore, Fst gene delivery increased the expression of fibroblast growth factor 21 (Fgf21) and adiponectin (AdipoQ) in WAT. Collectively, these findings identify Fst as a novel anti-atherogenic regulator that protects against vascular disease by promoting adipose browning, improving lipid metabolism, and activating Arg1-mediated metabolic pathways."

Efficient resolution requires efferocytosis-induced macrophage proliferation (EIMP) to expand pro-resolving macrophages. Here, we show that efferocytosis activates base excision repair (BER) to remove 8-OHdG from DNA, enabling EIMP. Mechanistically, efferocytosis promotes poly(ADP-ribose) polymerase-1 (PARP1) chromatin binding and PARylation to facilitate DNA repair complex assembly, and increases nuclear MTH1/NUDT1, which hydrolyzes 8-OHdG. Both processes require DNA-methyltransferase-3A (DNMT3A), which is activated during efferocytosis. Using a model where dexamethasone-induced thymocyte apoptosis triggers efferocytosis-mediated thymic repair, we showed that DNMT3A is required for increases in nuclear PARP1/MTH1, oxidized DNA suppression, EIMP in thymic macrophages, and thymic repair. We next studied a human-relevant model of atherosclerosis regression, where efferocytosis drives protective lesional fibrous cap thickening. We compared WT mice with a model of DNMT3A-clonal hematopoiesis (CH), in which loss-of-function DNMT3A mutations promote atherosclerotic disease. Atherosclerosis regression in WT mice led to decreased nuclear 8-OHdG and increases in nuclear PARP1/MTH1 and EIMP in lesional macrophages and fibrous cap thickening, all of which were impaired in DNMT3A-CH regression. These findings reveal that efferocytosis initiates a BER pathway to allow macrophage proliferation for tissue resolution, with possible therapeutic relevance to atherosclerosis regression and DNMT3A-CH."

"abstract_text": "ID: 42547443\nTitle: [Research progress on the role of calcitonin gene-related peptide in the repair of diabetic wounds].\nAbstract: Diabetic wounds are a severe complication of diabetes, which can lead to amputation or even mortality in severe cases. While normal wound healing consists of four phases: hemostasis, inflammation, proliferation, and remodeling, diabetic wounds tend to become chronic and refractory primarily due to a prolonged inflammatory phase. In diabetic wounds, insufficient synthesis and release of endogenous calcitonin gene-related peptide (CGRP) is a critical upstream mechanism underlying the disrupted neuro-immune communication, the persistent inflammation, and the arrested wound healing process. In contrast to pure skin defect wounds, where CGRP is rapidly upregulated after injury, CGRP remains persistently low in diabetic wound tissue, consequently failing to drive macrophage polarization towards the M2 phenotype or promote vascular maturation and collagen fiber deposition in the later phase of inflammation. In the early inflammatory phase, CGRP exerts pro-inflammatory effects by enhancing angiogenesis and modulating macrophage polarization. In the late inflammatory phase, CGRP upregulates thrombospondin-1, promotes neutrophil apoptosis and phagocytic clearance, thereby inhibiting excessive inflammatory response and shifting the wound microenvironment from a pro-inflammatory state to a pro-reparative state. Restoring CGRP signaling reconstructs the neuroimmunomodulation axis and improves wound repair while relieving diabetic neuropathic pain. Engineered CGRP combined with intelligent delivery systems offers promising prospects for diabetic wound therapy. However, large-scale clinical trials are still required to validate its clinical efficacy and safety.

"abstract_text": "ID: 42528838\nTitle: The diet-microbiota-inflammation axis and colorectal cancer.\nAbstract: Colorectal cancer (CRC) is still one of the leading causes of cancer morbidity and mortality worldwide. There is increasing evidence that diet, gut microbiota, microbial metabolites and chronic inflammation are important factors in colorectal carcinogenesis and may provide novel opportunities for prevention, diagnosis and treatment. To provide a comprehensive review of the current evidence on the role of diet, nutrition, microbial metabolism and chronic inflammation in CRC, with emphasis on emerging translational applications including microbiome-based biomarkers and microbiota-targeted therapeutic strategies. A literature search was performed with PubMed, Scopus and the Cochrane Library. Relevant studies on diet-microbiota interactions, microbial metabolites, inflammatory mechanisms, colorectal carcinogenesis, microbiome-derived biomarkers, and microbiota-targeted interventions were identified and reviewed. Preclinical and clinical studies and high quality reviews and meta-analyses were considered. Dietary patterns have been shown to have a major impact on the composition and function of the gut microbiota. Rich-fiber diets and short-chain fatty acids (SCFAs) production seem protective against CRC, while western dietary patterns, ultra-processed foods and dysbiosis-associated metabolites promote a pro-inflammatory environment associated with carcinogenesis. Some microorganisms such as Fusobacterium nucleatum, enterotoxigenic Bacteroides fragilis and pks-positive Escherichia coli have been associated with CRC by inflammatory, genotoxic and immune-modulatory mechanisms. Recent advances in sequencing technologies and multi-omics approaches have enabled the identification of microbial signatures with potential diagnostic and prognostic value. Moreover, microbiota-targeted interventions such as probiotics, prebiotics, postbiotics, faecal microbiota transplantation, and next-generation microbial therapies have yielded promising preclinical and early clinical results. The diet-microbiota-inflammation axis is a key player in colorectal carcinogenesis and a promising target for translational research. Microbiome-based biomarkers and microbiota-targeted therapies may have a role in future precision prevention and personalised management strategies of colorectal cancer despite significant challenges in terms of causation, standardisation and translation into clinical practice."

"abstract_text": "ID: 42549200\nTitle: Differential shaping of equine gut microbiota structure and function by breed and feeding regimen.\nAbstract: The gut microbiota plays an essential role in host energy metabolism and immune function. Horses are non-ruminant herbivores that rely heavily on hindgut microbial fermentation to meet their energy requirements. However, the relative contributions of host genetic background (breed) and environmental factors (feeding regimen and geographical location) to shaping the equine gut microbiota remain poorly understood. In this study, 16S rRNA gene sequencing and functional prediction analysis were performed on 139 equine fecal samples to systematically investigate the differential effects of breed and feeding regimen on the gut microbiota. Samples were collected from 30 Thoroughbreds (TH), 31 stabled hybrid horses (HH1), 30 grazing hybrid horses (HH2) (with HH1 and HH2 sired by Thoroughbreds out of Mongolian mares), 32 Mongolian horses (MH), and 16 Warmblood horses (WBH1 and WBH2). Alpha and beta diversity analyses, taxonomic profiling, and PERMANOVA were used to assess microbial composition and the contributions of different factors. Alpha diversity analysis revealed that the richness and diversity of the TH, HH1, HH2, and MH groups were significantly higher than those of the Warmblood horses (p\u202f<\u202f0.001), with Mongolian horses exhibiting the highest diversity and the hybrids showing intermediate levels between their parental breeds. Regarding taxonomic composition, the TH, HH1, HH2, and MH groups shared a microbial structure dominated by Firmicutes and Bacteroidota, yet each possessed distinct characteristics: Thoroughbreds were enriched with Treponema; Mongolian horses harbored the highest abundances of Rikenellaceae_RC9_gut_group and NK4A214_group; and the grazing hybrid horses developed a fiber-degrading bacterial community centered on Ruminococcus and Fibrobacter, demonstrating breed-specific microbial features. In contrast, the Warmblood horses exhibited a gut microbiota with distinct features characterized by significantly reduced microbial diversity and core fiber-degrading genera, concomitant with an enrichment of environmental-associated bacteria from the phylum Proteobacteria (e.g., Acinetobacter, Stenotrophomonas) and other genera (e.g., Comamonas, Brevundimonas). PERMANOVA analysis further quantified the contributions of different factors: breed explained 44.8% of the total variation (R\u00b2 = 0.448, p < 0.001), followed by feeding regimen (10.3%, p < 0.001) and geographical location (2.7%, *p* < 0.01), confirming breed as the predominant factor. This study provides evidence that breed establishes the foundational framework of the gut microbiota, while feeding regimen performs fine-tuning functions. We also systematically characterized the unique microbial composition of Warmblood horses, offering a scientific basis for breed-specific health management, precision nutritional interventions, and future disease risk monitoring in horses. Although all horses appeared clinically healthy, the distinct microbial composition observed in Warmblood horses warrants further investigation to determine its biological significance."

Yet how these diverse signals are molecularly integrated remains unknown. Here we show that clock, diet, and temperature cues converge on the orphan mitochondrial transporter, SLC25A34, to orchestrate thermogenic cycling of lipid synthesis and oxidation. During sleep, the clock suppresses Slc25a34 transcription through REV-ERB\u03b1. Waking, lipid-rich diets, or cold exposure abolish this repression, allowing lipolytic signals to stimulate Slc25a34 expression via PPAR\u03b1. SLC25A34 then imports oxaloacetate into mitochondria to accelerate the export of substrates used for acetyl-CoA production in the cytosol. This feeds into cytosolic lipid synthesis and transcriptional induction of mitochondrial biogenesis, which collectively promote mitochondrial lipid oxidation. Thus, SLC25A34 confers circadian, dietary, and environmental control of thermogenic metabolism through interorganellar lipid cycling."

"abstract_text": "ID: 42544286\nTitle: Can increasing footwear bending stiffness ameliorate age-related mechanical and metabolic deficits in walking?\nAbstract: Older adults consume metabolic energy faster than their younger adult counterparts while walking, particularly on sloped terrain. This increased rate is likely in part due to an age-related shift in moment and power production from the ankle joint to the hip. Shifting these mechanics proximally may occur due to older adults losing more mechanical energy at the foot and producing lower ankle joint moments, deficits that are exaggerated when walking uphill or against impeding forces. A promising method to target some of these foot and ankle mechanics differences is increasing footwear longitudinal bending stiffness via carbon fiber insoles. We examined how increasing footwear stiffness alters older adult (9F/10M, 70\u00a0\u00b1\u00a05.9 yrs) walking energetics across slopes. Increasing footwear stiffness reduced the magnitude of negative power from the foot+shoe structures distal to the forefoot, but increased negative power of the foot+shoe structures distal to the hindfoot (foot+shoe complex as a whole). At the ankle, peak joint moment increased by \u223c10% in the stiffest footwear compared with the baseline standardized shoe. Neither knee and hip mechanics nor net metabolic power were consistently affected by footwear stiffness. These results indicate that increasing older adult footwear stiffness via flat carbon fiber insoles attenuates some age-related deficits in foot and ankle mechanics, but does not result in a clear attenuation of the age-related distal to proximal shift in joint mechanics or clear metabolic benefits. The increase in ankle joint moment with stiffer footwear could be useful longer-term as a means to strengthen the calf musculature of older adults. Future work should examine the effects of footwear stiffening on ankle muscle-level outcomes such as force production, excitation, and fascicle mechanics."

To investigate the time-of-day effects of high-intensity interval resistance training (HIRT) on metabolism, adiposity, and adipogenic markers, male Swiss mice (n\u2009=\u2009111) were allocated to control or HIRT groups during the light (C6 and T6) or dark phase (C18 and T18). HIRT was performed for 8\u2009weeks (3 sessions/week) on a ladder at 90% of maximal load until exhaustion. Metabolic biomarkers, adiposity, adipocyte morphology, and protein expression of PPAR\u03b3 and adiponectin were assessed. Maximal strength increased in trained groups. Training-time interactions were observed for triglycerides and total cholesterol, with higher values in T6 than in C6 and T18. Glucose and PPAR\u03b3 were higher during the dark phase. PPAR\u03b3 was also higher in trained than control groups, irrespective of the time of day. HIRT reduced adiposity across multiple depots regardless of training time. No significant differences were observed for adipocyte area, adiponectin, insulin, or HOMA-IR. HIRT reduced adiposity independently of training time, suggesting that chronic adaptations in adipose tissue were primarily driven by the training. However, time of day modulated metabolic responses, particularly lipid metabolism."

In contrast to heart failure with reduced ejection fraction (HFrEF), few disease-modifying therapies exist for HFpEF, reflecting differences in pathophysiology. Low fermentable fiber (FF) intake, gut dysbiosis, and depletion of short-chain fatty acids (SCFAs), microbial metabolites central to immune, metabolic, and vascular homeostasis, are increasingly linked to the pathophysiology of HFpEF. Here, we synthesize preclinical and clinical evidence on FF and SCFAs and evaluate their therapeutic relevance to HFpEF. Preclinical studies demonstrate that FF supplementation or direct SCFA administration improves cardiometabolic function and attenuates cardiac remodeling through SCFA receptor signaling, enhanced nitric oxide bioavailability, reduced inflammation, and metabolic support of the energy-starved failing heart. Supporting the translational relevance of these findings, a systematic review of 27 human randomized controlled trials showed that FF interventions exert microbiome-mediated effects, enriching SCFA-producing taxa and augmenting fecal and circulating SCFA levels, while improving insulin sensitivity and reducing abdominal adiposity and LDL cholesterol. Direct SCFA supplementation increases SCFA availability and provides modest metabolic benefits, including reduced adiposity and liver fat. However, its effects are inconsistent. Collectively, these findings provide a mechanistic and translational rationale for FF-based interventions in HFpEF. To date, no clinical trials have evaluated the effects of FF on HFpEF-specific outcomes. Clinical studies are therefore needed to determine whether increasing FF intake can improve symptoms, cardiac function, and disease progression in HFpEF."

Increasing evidence suggests that these effects may involve interactions with the gut microbiota, intestinal barrier, and host inflammatory pathways. This narrative review summarizes current evidence on the impact of olive oil, olive-derived phenolics, and olive oil-rich dietary patterns on gut microbiota modulation, barrier function, inflammatory bowel diseases, and related systemic outcomes. The available literature indicates that olive oil may interact with the gut ecosystem through both its oleic acid-rich lipid matrix and its minor phenolic fraction. VOO and EVOO appear more consistently associated than refined oils with microbial or microbial metabolite profiles related to saccharolytic metabolism, short-chain fatty acid production, mucus-layer dynamics, and anti-inflammatory intestinal environments. Olive-derived phenolics, including hydroxytyrosol, tyrosol, oleuropein derivatives, and oleocanthal, can undergo microbial biotransformation and may influence bile acid metabolism, epithelial barrier integrity, and inflammatory signaling. Whole EVOO evidence is strongest in experimental colitis models, whereas human evidence mainly supports effects on postprandial endotoxemia, lipid oxidation, and selected inflammatory markers. However, findings remain heterogeneous and depend on oil quality, phenolic composition, comparator fat, dietary context, and host condition. Well-controlled human studies directly comparing EVOO, VOO, refined olive oil, and oleic acid-rich controls are needed to clarify reproducible microbiota-mediated effects and their relevance to intestinal and systemic health."

However, DHA enrichment in ruminant milk is limited by inefficient post-absorptive transport. This study evaluated whether combined supplementation of rumen-protected algae powder (RPA) and rumen-protected choline (RPC) enhances DHA enrichment in goat milk. Nine lactating dairy goats were assigned to three groups (n = 3/group) for 28 days: RPA alone, RPA + low-dose RPC (5 g/d), and RPA + high-dose RPC (10 g/d). Milk DHA content, bioconversion efficiency, serum biochemical parameters, and lipid profiles were analyzed. Compared with RPA alone, low- and high-dose RPC increased milk DHA content to 27.98 and 33.50 mg/100 mL, respectively, representing increases of 23.0% and 47.3%, and enhanced DHA bioconversion efficiency to 20.66% and 24.29% compared with 16.86% in the RPA group. RPC supplementation increased serum VLDL and triglyceride concentrations, and lipidomics revealed increased DHA-containing triglycerides (TG-DHA). These findings suggest that RPC may enhance DHA enrichment in goat milk by promoting VLDL-mediated DHA transport. Further studies with larger animal populations are required to confirm these effects. These findings contribute to a better understanding of nutritional regulation of DHA transfer and provide insights into strategies for developing DHA-enriched dairy products."

Here, we identify tissue-resident macrophages (TRMs) as central coordinators of age-related organ decline through impaired clearance of senescent neutrophils, a process regulated by the immunomodulatory prostaglandin E2 (PGE2) receptor EP2. Reducing TRM EP2 signaling in aged mice preserved youthful mitochondrial fitness and prevented cognitive decline, frailty, sarcopenia, adiposity, cardiac impairment, and systemic inflammation. Plasma proteomics implicated the liver as a major source of age-associated immune change, in which reduced TRM EP2 signaling rescued neutrophil efferocytosis and prevented paracrine stress in neighboring cells. Elevated TRM EP2 expression and senescent neutrophils were also observed in aged and diseased human tissues. Pharmacologic EP2 inhibition restored youthful neutrophil clearance, establishing impaired TRM efferocytosis as a reversible driver of organ decline in aging."

Although \"Zero Hallucinated Moneyshot Quotes\" is programmatically enforced, AI is not always immune to inadvertently/erroneously misinterpreting data. This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\n\"Clinically prescribed periodic \"fasting\" (caloric restriction), combined with dietary modification to include Omega-3 polyunsaturated fatty acids from fish and monounsaturated fats from olive oil, dietary fibers, and polyphenols from rich plant compounds may lower or balance toxic accumulated ceramides (like C16:0) via inhibition and metabolic processing in order to reduce organ aging and improve Circadian Efferocytosis Oscillation.\"\n\nThe claim is **plausible (Alignment Score 5)**. The provided literature supports that caloric restriction, polyphenol intake, and intermittent fasting modify ceramide profiles (specifically reducing species such as C16:0) and improve metabolic markers. While the literature explicitly links these interventions to metabolic homeostasis and improved efferocytosis in aging or disease contexts, the specific terminology \"Circadian Efferocytosis Oscillation\" as a unified clinical target is not standard, though biological cross-talk between circadian rhythm regulation, lipid metabolism, and macrophage function is well-established in the source material.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nPeriodic fasting and specific dietary modifications\u2014rich in Omega-3s, monounsaturated fats, dietary fibers, and polyphenols\u2014exert a regulatory effect on ceramide metabolism. These interventions decrease the accumulation of lipotoxic species such as C16:0, thereby mitigating metabolic dysregulation and organ aging. Mechanistic evidence links these nutritional strategies to the modulation of circadian genes, mitochondrial function, and macrophage-mediated efferocytosis.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe accumulation of signaling sphingolipids, particularly ceramides, is a hallmark of metabolic dysfunction and chronic inflammation. Caloric restriction (CR) and intermittent fasting (IF) serve as potent modulators of these lipid species. Research demonstrates that \"CR was associated with increased high-molecular-weight (HMW) adiponectin and reduced circulating ceramide species implicated in insulin resistance, including C16:0, C18:0, and C24:0.\" Furthermore, dietary patterns such as the Mediterranean diet, characterized by high olive oil and fiber content, are associated with cardiometabolic benefits. Mechanistically, \"Polyphenol-rich foods and caloric restriction may also reduce Cer concentrations and improve metabolic markers.\" \n\nBeyond metabolic reduction, these lipid mediators are intrinsic to the cellular resolution of injury. \"Efferocytosis, the clearance of apoptotic cells by macrophages, promotes tissue resolution.\" The link between nutrient timing and these processes is grounded in circadian biology, as \"The circadian system regulates physiological and metabolic processes, and exercise timing may influence metabolism and adiposity.\" Disruptions in these pathways, specifically in \"low fermentable fiber (FF) intake, gut dysbiosis, and depletion of short-chain fatty acids (SCFAs), microbial metabolites central to immune, metabolic, and vascular homeostasis, are increasingly linked to the pathophysiology of HFpEF.\" Ultimately, the alignment of dietary intake with endogenous rhythms may provide a therapeutic axis to preserve mitochondrial fitness and promote tissue repair.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Caloric restriction acts as a direct inhibitor of ceramide accumulation, specifically targeting species linked to insulin resistance.\n* The gut microbiota serves as a primary hub for transforming dietary fiber into short-chain fatty acids (SCFAs) that regulate efferocytosis.\n* There is a distinct circadian control over peroxisomal import in cortex glia, which oscillates and modulates lipid metabolism.\n* Efferocytosis itself activates DNA repair mechanisms (base excision repair) to facilitate macrophage proliferation and tissue resolution.\n* Omega-3 polyunsaturated fatty acids (such as DHA) protect against palmitic acid-induced lipotoxicity in Schwann cells.\n* CGRP signaling acts as a neuro-immune regulator that drives macrophage polarization toward a pro-reparative phenotype in wounds.\n* The \"gut-muscle axis\" allows polysaccharides to regulate lipid metabolism and antioxidant defense, influencing physical tissue quality.\n* Metabolic rhythmicity, mediated by clock genes, synchronizes hepatic lipid transport and yolk precursor formation in avian models.\n* Circadian disruption, such as that seen in night shiftwork, creates internal metabolite misalignment (e.g., uridine and bile acids) linked to cardiometabolic disease.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

In a 24-month non-blinded randomized controlled trial (Clinicaltrial.gov: NCT00427193) of non-obese (BMI 22-27.9\u2009kg/m2) men and premenopausal women aged 21 to 50 years, we assessed prespecified outcomes. Participants were randomized to an ad libitum or CR diet. We found that CR was associated with increased high-molecular-weight (HMW) adiponectin and reduced circulating ceramide species implicated in insulin resistance, including C16:0, C18:0, and C24:0. Mediation analysis indicated that reductions in ceramides were statistically compatible with partial mediation of the CR-associated improvements in insulin secretion, insulin sensitivity, and IGF-1 signaling markers. These effects were most pronounced at 12 months and attenuated by 24 months, suggesting partial metabolic adaptation over time. Overall, our findings are consistent with a model in which CR remodels bioactive lipid profiles and may enhance glucose metabolism in part through an adiponectin-ceramide-linked mechanism, highlighting a potential therapeutic axis for enhancing metabolic health.\n\nID: 42360463\nTitle: Metabolomic profile differs between LADA and type 1 diabetes identifying tryptophan metabolism as a pathway involved in the heterogeneity of autoimmune diabetes.\nAbstract: The heterogeneity of autoimmune diabetes may be associated with variable metabolic alterations. Our aim was to investigate differences in the metabolomic and lipidomic profile of autoimmune diseases and to identify pathways linked to beta cell damage. To this end, we compared latent autoimmune diabetes in adults (LADA) and type 1 diabetes, also comparing them with rheumatoid arthritis (RA), a related autoimmune condition, and healthy control participants. Metabolomic and lipidomic analyses were performed for 136 individuals (49 with LADA, 44 with type 1 diabetes, 29 with RA and 14 control participants). Omics of pancreatic islets from healthy donors were also evaluated after in vitro treatment with proinflammatory cytokines. LADA and type 1 diabetes differed from RA in terms of lipidomics and metabolomics. Phosphatidylethanolamines, ceramides, lysophosphatidylcholine and several metabolites at the entry sites of the tricarboxylic acid cycle were higher in type 1 diabetes compared with LADA. In pancreatic islets treated with proinflammatory cytokines, tryptophan concentration was reduced by 80%, indicating the activation of tryptophan metabolism in response to the inflammatory stimulus. In people with autoimmune disorders, kynurenine/tryptophan ratio (Kyn/Trp), a marker of tryptophan pathway activation, was higher than in the control group (Kyn/Trp ratio in control group, median [25th-75th percentile]: 0.014 [0.012-0.019]), with a progressive decline from RA (0.027 [0.022-0.032]) to LADA (0.021 [0.018-0.024]) and then to type 1 diabetes (0.018 [0.014-0.022]), ANCOVA p<0.0001. In LADA, Kyn/Trp was directly associated with fasting C-peptide levels in the multivariate regression model accounting for confounders (p=0.038). Metabolomic and lipidomic profiles differ between LADA and type 1 diabetes and vs RA, providing new insights into the heterogeneity of autoimmune diabetes. Our results confirm the involvement of tryptophan metabolism in autoimmune disorders, suggesting that the impaired activation of this pathway of immune tolerance in LADA is less pronounced than in type 1 diabetes, consistent with its milder degree of beta cell loss.\n\nID: 42186347\nTitle: Genetic ancestry-concordant ceramide metabolism and response to androgen receptor pathway inhibition in metastatic castration-resistant prostate cancer.\nAbstract: The authors observed differences in response between Black and White patients with metastatic castration-resistant prostate cancer (mCRPC) who were treated prospectively with androgen receptor pathway inhibition (ARPI) in the Abi Race and PANTHER studies. In addition, genetic ancestry-related single nucleotide variants in ceramide metabolism genes were associated with the time to prostate-specific antigen progression in the Abi Race study. For this report, the authors analyzed ceramide metabolites and their association with response to ARPI treatment in the Abi Race and PANTHER studies. Fasting serum levels were obtained from 22 Black patients and 22 White patients in the Abi Race trial and from 28 Black patients and 37 White patients in the PANTHER trial who were evaluable pretreatment and on treatment. After metabolomic profiling using the Biocrates MxP Quant 500 Kit and liquid chromatography/tandem mass spectrometry quantification of sphingolipids, differences in ceramide metabolites by race and timepoint and associations of ceramide metabolites with outcomes were evaluated. Pretreatment total ceramide levels were lower among Black patients compared with White patients who had mCRPC. Among pretreatment ceramide levels, Black patients had higher C24:C16 ceramide ratios compared with White patients. During ARPI treatment, Black patients had lower C24:C16 ceramide ratios, whereas the majority of C24:C16 ceramide ratios were higher during treatment among White patients. Ceramide metabolites were associated with the time to prostate-specific antigen progression, radiographic progression-free survival, and overall survival among Black and White patients with mCRPC who received ARPI, with higher expression of the ceremide Cer(d18:1/20:0) associated with shorter radiographic progression-free survival and worse overall survival among Black patients who received treatment with apalutamide and abiraterone. This study identified genetic ancestry-concordant ceramide metabolites that were associated with outcomes in patients with mCRPC who received treatment with ARPI from the Abi Race and PANTHER studies (ClinicalTrials.gov identifiers NCT01940276 and NCT03098836, respectively).\n\nID: 42177689\nTitle: Associations of coffee, alcohol, medication and supplement use with the metabolome and lipidome: an observational study of premenopausal women.\nAbstract: Lifestyle factors have been consistently linked to various health outcomes. However, few studies have comprehensively assessed how multiple of these factors are associated with metabolome and lipidome in a single study. We leveraged untargeted metabolomics and lipidomics to determine the associations of frequencies of alcohol and coffee intake, supplement and medication use, with metabolites and lipid species. This study consists of 702 premenopausal women who provided fasting blood samples. Final analysis included 857 metabolites and 828 lipid species. Multivariable linear regression models adjusted for confounders were used to investigate the associations. We corrected for multiple testing using Benjamini-Hochberg false discovery rate (FDR adjusted p-value\u2009<\u20090.01) and Bonferroni correction (Bonferroni-adjusted p-value\u2009<\u200910-\u20095). At FDR p-value\u2009<\u20090.01, the frequency of alcohol intake was associated with the largest number of biomarkers, including 89 lipid species (9 after Bonferroni correction) across several pathways (ceramides, phospatidylcholines, triacylglycerols, and androgenic steroids) and 123 (13 after Bonferroni correction) metabolites. Frequency of coffee intake was associated with 46 metabolites (27 after Bonferroni correction), with the strongest associations observed for quinate, 3-hydroxypyridine sulfate and trigonelline (N'-methylnicotinate). Frequency of multivitamin use was associated with 18 metabolites (6 after Bonferroni correction). Frequency of statin use was associated with 35 lipid species, respectively, but these were not significant after Bonferroni correction. Alcohol, coffee, and multivitamins are associated with several metabolites and lipid species. These findings offer valuable insights into potential biomarkers of exposure and molecular pathways through which these exposures may be associated with health outcomes.\n\nID: 42154475\nTitle: Effects of Dietary Carbohydrate Amount and Glycemic Index on Blood Lipidomic Signatures and Diurnal Postprandial Glucose Responses: The OmniCarb Trial.\nAbstract: We investigated whether lowering dietary carbohydrate content and glycemic index (GI) levels altered deep lipidomic profiles and whether these changes were associated with improved diurnal postprandial glucose response (PPGR). In the OmniCarb trial, 59 adults completed 5-week controlled feeding interventions (low carbohydrate/low GI vs. high carbohydrate/high GI) and 12-h meal tests. Comprehensive lipidomic profiling was performed to measure lipid species and lipid class-specific fatty acids (FAs) at the end of each intervention. We found that lowering carbohydrate content and GI levels significantly decreased triacylglycerols (TAGs) and phosphatidylcholines, while increasing lactosylceramides and phosphatidylethanolamines (PEs). Of 731 lipid species analyzed, 521 (71%) were significantly modified, including TAGs (n = 398), PEs (n = 45), and ceramides. Of 199 FAs analyzed across and within lipid classes, 89 showed significant changes (false discovery rate-adjusted P < 0.05), including decreases in saturated FAs (total and TAG FA12:0 and FA14:0) and palmitoleic acid and increases in very-long-chain saturated FAs, when lowering carbohydrate and GI levels. Between-diet changes in six total FAs and 17 lipid class-specific FAs were associated with half-day PPGR changes; greater decreases in joint FA score changes were linked to improved PPGRs. Our study suggests the potential importance of dietary carbohydrate-responsive lipidomic signatures in explaining individual variability in half-day PPGRs and may encourage future intervention studies to target these signatures. Carbohydrate diets with high glycemic index (GI) increase postprandial glucose response (PPGR) and diabetes risk; however, the pathways underlying individual variability in diurnal PPGRs to diets differing in carbohydrate content and GI remain unclear. We examined the effect of lowering dietary carbohydrate content and GI levels on comprehensive lipidomic pathways and tested whether these changes were associated with improved half-day PPGRs. Five-week controlled feeding interventions altered multiple lipid species and lipid class-specific fatty acids toward more favorable profiles, and composite fasting blood fatty acid scores derived from comprehensive targeted lipidomic profiling were associated with improved 12-h PPGRs. These lipidomic signatures explain individual variability in PPGRs and provide targets for future intervention studies.\n\nID: 42128408\nTitle: Gut commensal Bacteroides faecichinchillae, a potential novel candidate of next-generation probiotics targeting type 2 diabetes.\nAbstract: The implication of gut microbiota in the pathophysiology of type 2 diabetes, one of the major health concerns worldwide, has demonstrated the benefits of using probiotics to improve dysbiosis. Facing the lack of defined research strategy to found and qualify bacterial with real antidiabetic activity, we have developed a program to identify, select and validate novel strains able to improve metabolic alterations in type 2 diabetes. Among potential candidates, we identified Bacteroides faecichinchillae (named BAfa hereafter), and the present work presents the validation of the antidiabetic potential of the ST37 (DSMZ 26883) BAfa strain in mice fed a high-fat high-sucrose (HFS) diet for 10 weeks followed by 4 weeks of treatment. Daily gavage with live, but not heat inactivated, BAfa improved glucose tolerance, fasting hyperinsulinemia and liver triglyceride content in HFS fed mice. Furthermore, these beneficial effects were retained after lyophilization. Using this preclinical model, we characterised BAfa mechanism of action, showing that four weeks of treatment was associated with reduced hepatic accumulation of ceramides, key actors of insulin resistance. The underlying mechanism could be related to BAfa-induced changes in the intestinal bile acid profile and inhibition of the Fxr-Fgf15 pathway in the ileum. BAfa supplementation during 4 weeks in HFS fed mice was also associated with mild modifications of gut microbiota composition, with the upregulation of several species known for their beneficial metabolic actions (such as Lactobacillus johnsonii, Limosilactobacillus reutei, Roseburia, Turicimonas muris, Phocaeicola dorei or Akkermansia muciniphila) and for being up-regulated during metformin treatment. Altogether, these data indicate that BAfa and related B. faecichinchillae strains could be considered for developing next-generation probiotics to treat type 2 diabetes, potentially in combination with the anti-diabetic drug metformin.\n\nID: 42039969\nTitle: Intermittent fasting ameliorates diabetes-induced meibomian gland dysfunction in mice.\nAbstract: To investigate the effect of intermittent fasting (IF) on diabetes-induced meibomian gland dysfunction (MGD) in a mice model. The diabetic mice underwent an 8-week dietary intervention of ad libitum (AL) and IF diet. Meibomian gland (MG) proliferative potential, apoptosis, and ductal hyperkeratinization were assessed using immunofluorescence. Gene expression levels were evaluated by Western blot. Lipid accumulation was observed via LipidTox staining. Transmission electron microscopy (TEM) examined intracellular lipids and mitochondrial ultrastructure in acinar cells. Lipidomic and transcriptomic analyses compared MG gene expression and lipid profiles between groups. IF ameliorated diabetes-induced MGD. IF significantly improved diabetic MG proliferation, apoptosis and lipid metabolism imbalance, as well as improved the expression of the genes involved in lipid metabolism. Simultaneously, the results of lipidomics indicated that IF can effectively modify the types and content of lipids, especially ceramides and cholesterol esters. Transcriptomic results suggested that IF effectively ameliorated cell death and modulated ion channels signaling. IF could ameliorate cell death which might be mediated by the calcium ion signaling pathway to mitigate diabetes-induced MGD. These results provide direct evidence for the feasibility of dietary intervention to improve diabetes-induced MGD. IF can alter MG lipid composition and inhibit apoptosis in diabetic condition. The underlying mechanism may be associated with calcium ion signaling pathway.\n\nID: 42030580\nTitle: Dietary supplementation of Radix Isatidis polysaccharides improves meat quality in broilers by regulating lipid metabolism, antioxidant defense, and the gut-muscle axis.\nAbstract: This research assessed the impact of Radix Isatidis polysaccharides (RIPS) supplementation on the growth, meat quality, lipid metabolism, and gut microbiota of broiler chickens. A total of 320 AA broilers were separated into four groups and given either a basic diet or diets with 250, 500, or 1000\u00a0mg/kg RIPS for 42\u00a0days. We employed various multi-omics approaches, including serum biochemistry, lipidomics, transcriptomics, and 16S rRNA sequencing, to investigate the underlying mechanisms. The results indicated that 1000\u00a0mg/kg RIPS markedly enhanced meat color, elevated \u03c9-3 and \u03c9-6 polyunsaturated fatty acids, and augmented antioxidant activity in breast muscle. In the 500\u00a0mg/kg and 1000\u00a0mg/kg groups, alanine aminotransferase (ALT) activity was significantly decreased, and triglyceride (TG) levels were significantly reduced in the 1000\u00a0mg/kg group. Lipidomic analysis revealed that in the 1000\u00a0mg/kg group, the accumulation of triglycerides and ceramides in the chicken breast was lower, indicating an optimization of lipid metabolism. Transcriptomic analysis showed that in the ileum, the expression of FABP1 and APOA1 genes was significantly upregulated in the 1000\u00a0mg/kg group, suggesting improved fatty acid transport and cholesterol metabolism. RIPS also significantly improved the gut microbiota, particularly increasing the abundance of g__Actinomarinales and p__DTB120 in the 1000\u00a0mg/kg group, which were positively correlated with antioxidant capacity and meat quality. In summary, RIPS regulates lipid metabolism and antioxidant defense through the \"gut-muscle axis,\" leading to significant improvements in both meat quality and health in broiler chickens. This study emphasizes the potential of plant polysaccharides in animal nutrition and suggests 1000\u00a0mg/kg RIPS as an appropriate supplementation amount.\n\nID: 41850615\nTitle: Lipidomic remodeling of the brain and muscle in a zebrafish model of depression.\nAbstract: Major depressive disorder (MDD) is a highly prevalent and disabling psychiatric condition, increasingly recognized as a systemic disorder involving central and peripheral pathophysiological alterations. In this study, we used a multidimensional approach using zebrafish (Danio rerio) exposed to an unpredictable chronic stress (UCS) protocol as a model of MDD, to unravel the plasticity of the lipidome in this mental disorder. Behavioral analyses revealed a reduction in sociability and locomotor activity in stressed animals, accompanied by significantly elevated cortisol levels. Fatty acid profiling demonstrated a decrease in n-3 (omega-3) polyunsaturated fatty acids (PUFA) and an increase in n-3 (omega-6) PUFA, which was more evident in the brain than in the muscle. After UCS, lipidomic analysis revealed a remodeling of the brain lipid profile, including the modulation of several phospholipid and sphingolipid species that may impact cell membrane properties and cause neuronal dysfunction. Some of these species have been previously correlated with neuroinflammation and impaired neurotransmission. An increase in plasmalogen phospholipids, well-known endogenous oxidant signaling molecules, suggests a dysregulation of the redox state. In muscle, lipidomic alterations were characterized by elevated levels of acylcarnitines, indicative of altered mitochondrial energy metabolism, and ceramides, well-known pro-inflammatory and pro-apoptotic molecules. This study highlights the relevance of lipidomic plasticity in the pathophysiology of MDD, associated with behavioral effects similar to MDD symptoms.\n\nID: 41793053\nTitle: Molecular Mechanisms of Lipid-Modifying Enzymes in Cellular Adaptation and Systemic Glucose Homeostasis.\nAbstract: Lipid-modifying enzymes dynamically regulate membrane architecture, signaling compartmentalization, and inter-organ metabolic communication, thereby influencing systemic glucose homeostasis. Advances in lipidomics and structural enzymology reveal how enzymatic remodeling of phospholipids, sphingolipids, and acyl chains governs insulin receptor organization, PI3K-AKT signaling, and GLUT4 trafficking. Dysregulated lipid flux mediated by factors such as FABP4, ceramides, and diacylglycerols disrupts membrane microdomains, impairs \u03b2-cell function, and promotes hepatic gluconeogenesis and skeletal muscle insulin resistance. Conversely, omega-3 polyunsaturated fatty acids enhance membrane fluidity and anti-inflammatory signaling. Integrating lipid enzymology with metabolic physiology establishes a unified mechanistic framework linking membrane remodeling to insulin responsiveness and diabetes pathogenesis.\n\nID: 41727679\nTitle: Biliopancreatic diversion with duodenal switch improve polycystic ovary syndrome with decreased serum ceramides.\nAbstract: Polycystic ovary syndrome (PCOS) is characterized primarily by insulin resistance and reproductive disorders. Biliopancreatic diversion with duodenal switch (BPD/DS) could significantly improve insulin sensitivity with significantly elevated level of bile acids. We aimed to explore changes in PCOS manifestations after BPD/DS and the possible mechanisms. Twenty PCOS rat models were assigned into the BPD/DS group and the sham BD (S-BPD) group randomly. The fasting blood glucose, bile acids, and ceramides levels in serum samples were assessed. The reproductive disorders of BPD/DS group were almost completely restored 8 weeks after surgery, and the AUCOGTT value and the AUCITT value were statistically less than those of the S-BPD group (P =0.001). The concentration of serum testosterone, luteinizing hormone, and follicle-stimulating hormone of the BPD/DS group was statistically less than that of the S-BPD group (P <0.05). Moreover, high level of bile acids and low level of ceramides were observed in the BPD/DS group (P <0.001). Bile acid sequestrant was given to the BPD/DS group rats for 1 week, the level of bile acids decreased and ceramides increased, the insulin resistance worsened. The AUCOGTT value increased from 818.3 \u00b1 297.3 mmol/L\u00b7min to 1147.9 \u00b1 167.9 mmol/L\u00b7min (P =0.007) and the AUCITT value increased from 525.6 \u00b1 52.3 mmol/L\u00b7min to 577.7 \u00b1 102.9 mmol/L\u00b7min (P =0.023). Our study showed the improvement of insulin resistance in PCOS models after BPD/DS with decreased serum ceramides. The sequestrant of bile acid reversed the improvement of insulin resistance with higher ceramides level.\n\nID: 41621715\nTitle: Plasma lipidomics and 15-year risk of incident diabetes: a coronary artery risk development in young adults study.\nAbstract: Lipid metabolism has long been implicated in diabetes, but there has been a paucity of population-based studies of the plasma lipidome and incident diabetes in cohorts of early middle age. We used data from the US-based Coronary Artery Risk Development in Young Adults (CARDIA) Study to identify lipidomics associated with 15-year incident diabetes (n = 1,094; n = 162 incident diabetes; [mean (SD) age: 45 (3.6); 58% women; and 59% White race]). Plasma lipidomics was conducted using liquid-chromatography and infusion-mass spectrometry. Diabetes was defined at 5-, 10- and 15-year follow-ups as fasting glucose \u2265 126 mg/dl, 2-h glucose tolerance test \u2265 200 mg/dl, HbA1c \u2265 6.5%, or reported diabetic medication use. We tested associations between individual lipids and incident diabetes with interval-censored, multivariable-adjusted Cox proportional hazards regression, accounting for multiple comparisons. We used differential expression analysis to identify pathways upregulated and downregulated in participants who developed diabetes over the 15-year period. Finally, we used penalized regression (LASSO) to generate a lipid risk score for incident diabetes (0.7 training, 0.3 testing). In hazards regression, 156 lipids including glycerolipids, glycerophospholipids, and sphingolipids, were associated with incident diabetes. Of these, 56 lipids were also selected by LASSO regression as distinguishing participants who developed diabetes from those who did not. The lipid risk score's ability to improve prediction of 15-year incident diabetes past sociodemographic, behavioral, and clinical covariates was limited to the training set. Pathways leading to diacylglycerols and ceramides were upregulated, while pathways leading to hexosylceramides, lysophosphatidylethanolamines, triacylglycerols, and lysophosphatidylcholines were downregulated in incident diabetes cases. Our results in this cohort of early middle-aged adults, supports further investigation into the roles of glycerophospholipid and sphingolipid metabolism in diabetes development, particularly for ceramides and hexosylceramides.\n\nID: 41607106\nTitle: Unpacking the lipid-immune axis in health and disease.\nAbstract: The lipid-immune system relationship represents an important but overlooked axis of inflammation and host defense regulation. Radically different from an energy source or structural component, lipids influence immune cell regulation, signaling and inflammatory responses. This narrative review provides a broad overview of the role lipids play in immune regulation in both healthy and pathogenic states. We initiate the review by summarizing the role of a variety of lipid classes in immune cell biology, with an emphasis on explaining how lipid composition and metabolism influence both innate and adaptive immunity. Next, we analyze the role that lipid-based mediators eicosanoids, resolvins and ceramides play in regulating inflammatory and pro-resolving pathways. We observe dietary and circulatory lipids additionally direct the immune response and modulate the resolution of inflammatory processes. In diseases characterized by prolonged and persistent immune activation and low-grade inflammation, such as atherosclerosis, obesity, type 2 diabetes and autoimmune diseases, impaired lipid metabolism ultimately aids this persistent state of immune activation. Moreover, we also consider the emergent role of the lipid-immune interface in infectious disease, demonstrating ways in which pathogens can hijack or modify lipid metabolism to escape the host immune response. We cover the potential therapeutic implications of lipid-immune interactions, noting potential strategies using statins, omega-3 fatty acids, or specialized lipid mediators, all with the objective of modulating inflammation rather than broad immunosuppression. Finally, we also identify important knowledge gaps and will suggest avenues for future research, particularly the need for more integrated lipidomic and immunologic studies.\n\nID: 41590624\nTitle: The Effect of Short-Term and High-Intensity Functional Circuit Training on Plasma Lipidome Profiles of People Living with and Without HIV.\nAbstract: Both HIV infection and antiretroviral therapy contribute to dyslipidemia and abnormal body fat distribution in people living with HIV (PLWH). Exercise training is an effective intervention to protect against these metabolic changes. However, little is known about the mechanisms underlying the impact of exercise training on lipid metabolism in PLWH. This study aimed to comparatively evaluate the effect of high-intensity functional circuit training on the plasma lipidome of PLWH and HIV-negative subjects (control). PLWH (n = 13) and control (n = 14) were submitted to 8 weeks of exercise training. Body composition, anthropometric, and biochemical parameters were measured. Plasma was obtained in a fasting state for lipidomic analysis. Anthropometric and biochemical parameters revealed lower levels of leptin, HDL-C, body fat %, and BMI combined with elevated aspartate transaminase (AST) and Homeostasis Model Assessment of \u03b2-cell function (HOMA_beta) in PLWH when compared to control subjects that persisted from baseline to post-exercise training. Nonetheless, contrasting levels of adiponectin, fasting insulin, and phosphatidylcholine-containing lipids observed at baseline were equalized after training in PLWH. In control subjects, significant reductions in concentrations of triglycerides alongside phosphatidylinositol and glycosylated ceramides were observed post-exercise training. By contrast, PWLH displayed an increase in diglycerides, acylcarnitines, and free cholesterol levels after exercise training, together with decreased concentrations of free fatty acids, cholesteryl esters, and glycosylated ceramides. In addition to specific lipidome alterations in each group, particularly driven by improved insulin resistance in PLWH, this study showed concomitant modulation of several glycerophospholipids and sphingolipids, suggesting health-promoting effects of short-term exercise training. Collectively, these modulated lipid species represent interesting targets for future lipidomic-based studies evaluating not only the effects of exercise training but also the molecular mechanisms resulting in a healthier plasma lipidome profile.\n\nID: 41565918\nTitle: Elevated serum glucosylsphingosine level in children with obesity: relation to plasma atherogenesis.\nAbstract: Glucosylsphingosine (Lyso-GL-1), a glycosphingolipid formed by glucosylceramide hydrolysis, is known to be increased in Gaucher disease. Recently, increased ceramides and sphingolipids have been implicated in obesity, insulin resistance, and atherogenesis. However, limited data exists on serum Lyso-GL-1 level in children with obesity and its relation with insulin resistance, lipid dysfunction, and atherogenesis. Hence, this study aimed to assess Lyso-GL-1 level among children with obesity and correlate it with biomarkers of insulin resistance and atherogenic index of plasma (AIP). Sixty children with obesity with a mean age of 10.06 years (SDS\u2009\u00b1\u20092.22) and 60 age- and sex-matched normal-weighed controls were assessed for anthropometric measures, mean blood pressure percentiles, serum Lyso-GL-1, glycated hemoglobin (HbA1c), fasting insulin, triglycerides, cholesterol, low-density (LDL-C) and high-density lipoprotein cholesterol (HDL-C) with calculation of the homeostatic model assessment of insulin resistance (HOMA-IR) and the AIP. Children with obesity have significantly higher Lyso-GL-1 and AIP than controls. Lyso-GL-1 is significantly positively correlated with body mass index (BMI) z-score, waist/hip ratio z-score, systolic and diastolic blood pressure percentiles, LDL-C, HOMA-IR, and AIP (p\u2009<\u20090.05), being independently correlated with systolic blood pressure percentile, LDL-C, and AIP on multivariate regression analysis. Serum Lyso-GL-1 is elevated in children with obesity, being closely correlated with hypertension, insulin resistance, and atherogenesis. This could provide a mechanistic insight on the role of Lyso-GL-1 in obesity and atherogenesis. Further studies are warranted to explore the potential role of Lyso-GL-1 as a biomarker and target for the prevention and treatment of obesity-related atherogenesis and insulin resistance.\n\nID: 41390113\nTitle: Arsenic exposure, arsenic metabolism, and plasma lipidome in relation to type 2 diabetes and glycemic traits: a lipidome-wide association study.\nAbstract: Both arsenic exposure and lipid metabolism disturbances are implicated in type 2 diabetes (T2D), whereas arsenic-associated lipidomic alterations and their contributions to T2D remain unclear. To map the plasma lipidomic profiles of incident T2D, glycemic traits, and arsenic exposure/metabolism, and to assess the mediating roles of lipids in arsenic-related diabetogenesis. A nested case-control study of 92 incident T2D cases and 184 controls was conducted within an urban adult-based prospective cohort. Plasma lipidome and urinary arsenic species (As3+, As5+, MMA, DMA, and AsB) were measured. Orthogonal partial least squares-discriminant analysis, t-test, and conditional logistic regression were applied to identify T2D-associated lipids, while partial least squares regression, t-test, and linear regression were conducted to identify glycemic traits- and arsenic-associated lipids. Mediation analyses quantified lipid-mediated effects. Several arsenic exposure indicators (tAs, iAs, As3+, As5+, and DMA) were associated with increased T2D incidence (odds ratios [ORs]: 1.37-1.76), whereas metabolism indices (MMA% and primary methylation index [PMI]) showed protective associations with T2D (ORs: 0.59-0.61) and improved glucose homeostasis. We identified 163 T2D-associated lipids, characterized by increased triacylglycerols (TGs) and diacylglycerols (DGs) but reduced lysophosphatidylcholines, sphingomyelins (SMs), and hexosylceramides. Most TGs, DGs, and ceramides (Cers) were positively associated with fasting plasma insulin and HOMA-IR. Arsenic exposure was associated with higher TGs but lower DGs, Cers, and SMs. Efficient arsenic metabolism (higher DMA% and secondary methylation index [SMI]) was positively associated with most lipids, whereas MMA% and iAs% were inversely associated. Mediation analyses revealed 19 (mainly TGs/DGs), 16 (mainly SMs/phosphatidylcholines), and 35 (mainly TGs/Cers) lipids that partially mediated arsenic exposure-T2D, arsenic metabolism-T2D, and arsenic metabolism-insulin resistance associations, respectively, with mediation proportions of 11.4%-54.7%. Arsenic exposure and metabolism are associated with distinct lipidomic profiles that may precede T2D onset. Specific lipids partially mediated arsenic-related diabetogenic effects, providing candidate biomarkers and intervention targets.\n\nID: 41344402\nTitle: Modulation of ceramides through nutrition: A new target in obesity and insulin resistance (Narrative Review).\nAbstract: Ceramides (Cer) are signaling sphingolipids that participate in insulin signaling, mitochondrial integrity, and inflammation. In obesity and insulin resistance (IR), Cer biosynthesis is exacerbated, leading to metabolic dysfunction and chronic diseases. This narrative review synthesizes current evidence on how Cer metabolism can be modulated through dietary components and dietary patterns, with emphasis on lipidomic analyses. The synthesis and accumulation of Cer are influenced by dietary abundance and quality, such as carbohydrates, fat and phenolic compounds. High-fructose corn syrup and saturated fatty acids promote Cer accumulation and IR, while monounsaturated and polyunsaturated fatty acids-abundant in the Mediterranean and Nordic diets-attenuate these effects. Polyphenol-rich foods and caloric restriction may also reduce Cer concentrations and improve metabolic markers. The emerging evidence from lipidomic analyses is expanding our knowledge on the role of diet in Cer modulation. Nutritional strategies targeting ceramide metabolism represent a promising approach to improve metabolic health. Beyond their therapeutic potential, ceramides also emerge as dynamic lipidomic biomarkers capable of reflecting early metabolic changes and monitoring the efficacy of nutritional interventions.\n\nID: 41154683\nTitle: ApolipoproteinB48 Knockout Ameliorates High-Fat-Diet-Induced Metabolic Impairment in Mice.\nAbstract: This study aimed to investigate whether knockout of the ApoB48 gene improves lipid metabolism disorders induced by a high-fat diet (HFD) in mice. Clustered regularly interspaced short palindromic repeats-Cas9 gene editing technology was used to knock out the ApoB48 gene in C57BL/6J mice, and genotype identification showed heterozygosity (HE, ApoB48 +/-). Subsequently, eight HE and eight wild-type (WT) mice were fed a HFD for 12 weeks. Fasting blood glucose, and insulin levels were decreased in ApoB48 +/- mice. The intraperitoneal glucose tolerance test and intraperitoneal insulin tolerance test showed mild insulin resistance. Moreover, it delayed the development of atherosclerosis and intestinal tissue damage. Differential metabolites such as ceramide, sphingosine, and sphingosine-1-phosphate were identified using liquid chromatography-mass spectrometry, and differentially expressed proteins, including ceramide synthase 6 (CerS6), protein phosphatase 2A (PP2A), and protein kinase B (AKT), were indicated by the Kyoto Encyclopaedia of Genes and Genomes. Therefore, decreased expression of ApoB48 can ameliorate lipid metabolism disorders induced by an HFD, which may be related to the CerS6/PP2A/AKT pathway. This might represent a new approach for exploring methods to treat hyperlipidaemia.\n\nID: 41133433\nTitle: Lipidomic profiling unveils sex differences in diabetes risk: Implications for precision medicine.\nAbstract: Type 2 diabetes is a multifactorial condition whose greatest impact comes from its complications. We hypothesized that distinct insulin-derived mechanisms and lipid profiles discriminate sex differences and can be used to identify subjects at higher risk to develop diabetes-related complications. The PREVADIAB2 study evaluated metabolic alterations after 5\u2009years in individuals initially free of Type 2 Diabetes (PREVADIAB1). In this analysis, 953 participants were stratified into clusters using hierarchical clustering based on insulinogenic index (IGI), fasting insulin secretion rate, HOMA-IR, and fasting insulin clearance. A subset of participants (n\u2009=\u2009488) had their lipidome assessed using LC/MS-QTOF. Four clusters were identified: Liver Sensitive (LS), Pancreas Glucose Sensitive (PGS), Insulin Deficient (ID), and Insulin Resistant (IR), each with distinct dysglycemia risk. While metabolic features were similar across sexes, the parameter thresholds differed, resulting in sex-specific lipidomic profiles. Women exhibited higher levels of circulating dihydroceramides (5.3\u2009\u00b1\u20091.9 vs. 4.7\u2009\u00b1\u20091.8, p\u2009<\u2009.001), associated with de novo ceramide synthesis, and elevated sphingomyelins (SM), suggesting altered lipid metabolism. Conversely, the ceramide-to-SM ratio was higher in men (1.04\u2009\u00b1\u2009.21 vs. .90\u2009\u00b1\u2009.18, p\u2009<\u2009.001). Except for the LS cluster, all other clusters exhibit distinct lipid signatures associated with metabolic dysfunction, further accentuated by specific lipid profile sex differences. Distinct insulin-related metabolic features and sex identify different phenotypes with distinct lipidome profiles, highlighting the need to place prediabetes in a broader context of metabolism beyond glucose.\n\nID: 41112506\nTitle: Integration of Proteomic and Lipidomic Analysis Reveals Potential Markers of Insulin Resistance in Young Children With Obesity.\nAbstract: This study aimed to identify novel proteomic and lipidomic biomarkers of insulin resistance (IR) in young children with obesity and to assess the ability of hub lipids and proteins in the diagnosis of IR. The discovery cohort consisted of 50 prepubertal children, including 30 children with obesity and 20 lean. The validation cohort included 25 children with obesity and IR (obese-IR) and 25 children with obesity without IR (obese-NIR). Fasting plasma was collected from all participants for Olink proteomics and untargeted lipidomics. Pearson correlation analysis was used to identify proteins and lipids associated with IR, and area under the receiver operating characteristic (AUROC) was applied to compare the ability of the identified proteins and lipids with traditional indices in the diagnosis of IR. In the discovery cohort, a total of 15 lipids and 10 proteins had significant correlation with IR. In the validation cohort, protein fatty acid binding protein 4 (FABP4) and gene serpin family E member 1 (PAI) were overexpressed in obese-IR children compared to obese-NIR children, while insulin like growth factor binding protein 1 (IGFBP-1) and paraoxonase 3 (PON3) were lower in the IR group than in the obese-NIR group; five lipids including sphingosine (d16:0), coenzyme (Q8), ceramides phosphate (d42:2), phosphatidylethanolamine (37:2e), and phosphatidylcholine (18:1e_16:0), showed significant (p < 0.05) change in obese-IR children compared to obese-NIR children. In addition, the AUC-ROC was 0.89 for IGFBP-1, 0.81 for PON3, and 0.65 for PAI. The ability of IGFBP-1, PON3, and PAI to diagnose IR was better than that of adiponectin and leptin. The AUROC of phosphatidylcholine (18:1e_16:0) and coenzyme (Q8) were 0.80 and 0.73, respectively, which was significantly higher than the AUROC of triglycerides(TGs), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C). Proteomic and lipidomic analysis can allow for the identification of potential new candidate biomarkers for IR. The ability of novel biomarkers to diagnose IR was better than traditional indicators.

Aiming to clarify whether metformin-induced changes in the intestinal tract directly contribute to metabolic improvement, we evaluated the effects of escalating doses (from 50 to 200 mg/kg/day) of metformin orally administered for 4 weeks in mice made glucose intolerant by ten weeks of high fat high sucrose diet. Several intestinal parameters were studied, including caecal microbiota composition and bile acids profile, ileal FXR signaling, abundance of GLP1-producing cells and goblet cells and blood metabolome. Metformin restored glucose tolerance, fasting insulinemia and HOMA-IR index in a dose-dependent manner. Only a subset of gut-related effects, including mucus production and GLP-1 expression, exhibited a parallel dose-response relationship, suggesting a possible contribution to the observed metabolic improvements. In contrast, other changes, including ileal Fxr-Fgf15 inhibition and hepatic ceramide reduction did not scale with dose, suggesting they are not the main drivers of metformin dose-dependent effects on glycemic control. We also pointed out marked differential sensitivity of gut bacteria to metformin supporting complex interactions of the drug with the microbial ecosystem. Finally, metformin enhanced the proliferation of intestinal epithelium, resulting in increased length of ileal villi. Altogether, this study offers new insights into the metformin mechanism of action and revealed potential novel microbial biomarkers and targets for enhancing its therapeutic efficacy.\n\nID: 41002985\nTitle: Impact of Dietary Interventions on the Human Plasma and Lipoprotein Lipidome.\nAbstract: Lipids are structurally diverse biomolecules that play essential roles in cellular function, energy storage, and signaling. The human lipidome, a dynamic and complex subset of the metabolome, is shaped by both endogenous factors, such as genetics, sex, age, and metabolic health, and exogenous influences like lifestyle, diet, and microbiota. Among these, diet stands out as one of the most modifiable and impactful determinants, influencing lipid composition across plasma, serum, and lipoprotein fractions. While traditional lipid profiling provides limited insight, lipidomics enables comprehensive characterization of lipid species, revealing mechanistic links between lipid metabolism and diseases such as cardiovascular disease (CVD), metabolic syndrome (MetS), and inflammatory disorders. This review explores: (1) the relationship between lipid profiles and CVD risk, (2) the internal and external modulators of the lipidome, and (3) current evidence on how specific dietary patterns, including Mediterranean, Nordic, low glycemic, and vegetarian diets, and individual nutrients such as omega-3 fatty acids (FAs), plant sterols, and mycoprotein, influence lipidomic profiles. Advances in lipidomics highlight that dietary fat quality, food matrix, and eating patterns can significantly modulate lipid species such as triacylglycerols (TAGs), ceramides (Cers), and phospholipids, with implications for cardiometabolic health. Notably, distinct responses are observed across plasma High-Density Lipoprotein (HDL) and Low-Density Lipoprotein (LDL) lipidomes, emphasizing the need for compartment-specific analyses. Understanding these diet-lipidome interactions offers promising avenues for precision nutrition and the development of lipid-based biomarkers for disease prevention and management.\n\nID: 40887333\nTitle: Long-chain and very long-chain ceramide levels in subjects with impaired glucose regulation.\nAbstract: The aim of this study was to determine the ceramide subspecies profile in people with impaired 1-hour or 2-hour postload glucose during a 75 g oral glucose tolerance test (OGTT) and their association with cardiometabolic parameters. Out of 90 subjects (age 46.7 \u00b1 10.5 years; body mass index of 32.0 \u00b1 6.3 kg/m2) who underwent a 2-hour OGTT, 19 had normal glucose tolerance, 22 had 1-hour plasma glucose \u22658.6 mmol/L (1hrOGTT), and 49 had 2-hour >8.6 and \u226410 mmol/L (impaired glucose tolerance). Homeostatic model assessment of insulin resistance (HOMA-IR) was determined for each group and was subdivided into 2 subgroups (HOMA-IR <2.5 or \u22652.5). Areas under the curve (AUCs) for glucose, insulin, C-peptide, and triglycerides were calculated during the OGTT. Ceramides were assessed by liquid chromatography-mass spectrometry on a fasting blood sample. There was no significant difference across the glucose tolerance groups, as well as the subgroups depending on HOMA-IR, for all evaluated lipid markers and ratios. The AUCC-peptide was positively associated with C16 (r = 0.21, P = .051), while a negative relationship was apparent between the insulin secretion-sensitivity index-2 and C24 (r = -0.21, P = .051), HOMA-IR \u22652.5 and the C16/24 (r = -0.22, P = .034), C18/24 (r = -0.22, P = .037), and C24:1/C24 (r = -0.24, P = .022) ratios. Our results demonstrate diminished C16/C24 and C18/C24 ratios in subjects with insulin resistance, and an independent relationship between C16:0 ceramide and stimulated insulinemia, and between C16 and C18 and kidney function, highlighting the leading role of specific ceramide subspecies rather than the overall ceramide levels for the cardiometabolic profile in early stages of glucose intolerance.\n\nID: 40849529\nTitle: Characterizing plasma lipid species in metabolic dysfunction associated steatotic liver disease in persons with type 1 diabetes.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) is the hepatic manifestation of metabolic syndrome. Hepatic lipotoxicity and inflammation are two key factors driving progression of steatosis to metabolic dysfunction-associated steatohepatitis (MASH). The presence of MASH increases the risk of cardiovascular events, cirrhosis, hepatocellular carcinoma (HCC) and non-liver malignancies. Although MASLD and lipid species have been extensively examined in persons with type 2 diabetes, much less is known in type 1 diabetes. We examined the association of key lipid species with MASLD in individuals with type 1 diabetes. We designed a cross-sectional study of 30 participants with type 1 diabetes recr1uited from our institutional diabetes clinics. All participants had fasting blood drawn for targeted lipidomics and underwent a FibroScan. Those with steatosis score of\u2009\u2265\u2009248 as determined by controlled attenuation parameter (CAP) were categorized as cases (n\u2009=\u200917); those with steatosis score\u2009<\u2009248 were categorized as controls (n\u2009=\u200913). BMI was significantly higher in cases than controls (P\u2009=\u20090.0007) and used significantly higher 24-h insulin doses than controls (P\u2009=\u20090.004). Cases displayed significantly higher circulating levels of total ceramides (P\u2009=\u20090.02), diacylglycerols (P\u2009=\u20090.0009) and triacylglycerols (P\u2009=\u20090.0004). The two groups displayed similar levels of hexosylceramides, dihydrosphingomyelins, sphingomyelins, and phosphatidylcholines. Similar to previous findings, numerous sphingolipids species, diacylglycerols, and triacylglycerols were found to correlate positively with higher BMI and 24-h insulin dose. Total circulating dihydroceramides, ceramides, diacylglycerols, and triacylglycerols levels significantly correlated with steatosis score (P\u2009<\u20090.05). None of the lipid species correlated with fibrosis score. These results suggest that persons with type 1 diabetes and MASLD have a higher BMI, are likely to be insulin resistant, and display elevated circulating levels of dihydroceramides, ceramides, diacylglycerols, and triacylglycerols, which are strongly associated with the pathogenesis of steatotic liver disease.\n\nID: 40785181\nTitle: Mediterranean Pattern Diet in Multiple Sclerosis: A Review Focusing on Immunometabolites.\nAbstract: Multiple Sclerosis (MS), the most common demyelinating disease of the Central Nervous System (CNS), is characterized in its pathogenesis by an interplay of mechanisms pertaining to aberrant immune response, acute and chronic inflammation, glial housekeeping, and neuron survival, ultimately resulting in demyelination, synaptic dysfunction, and neuroaxonal loss. Experimental models as well as epidemiological observations support the hypothesis of a role of diet in the disease onset, activity, and progression. It has been suggested that Western-type diets might be detrimental, while on the other hand, certain dietary regimens, like Mediterranean, low-fat, ketogenic, or intermittent fasting, might lead to disease amelioration, possibly through differential regulatory effects upon inflammation, immunity, and regenerative processes of neurons and glia. Under this perspective, immunometabolites, small intermediates including among the others citrate, itaconate, lactate, glutamate, glutamine, alfa-ketoglutarate, 2-hydroxyglutarate, fumarate, ceramides, whose turn-over reflects metabolic reprogramming of immune cells, might be viewed as significant regulators of cellular responses against either local or systemic noxious stimuli, both in the periphery and in the CNS. The present narrative review aims at summarizing current experimental and clinical evidence regarding the role of immunometabolites in shaping MS pathology, to address whether they could be relevant either as disease markers or therapeutic targets, and whether they might be differentially influenced by dietary approaches, especially by Mediterranean Pattern Diets (MPD).\n\nID: 40630937\nTitle: Selective association of plasma sphingolipid species with insulin sensitivity and secretion in normoglycemic Black and White American adults.\nAbstract: Ceramides and other sphingolipids are associated with diabetes risk. Here, we examined the association of plasma sphingolipids with insulin sensitivity and secretion in people without diabetes. We enrolled adults without diabetes based on 75-g oral glucose tolerance test. Assessments included clinical examination, insulin sensitivity (hyperinsulinemic euglycemic clamp), and insulin secretion (intravenous glucose tolerance test). Plasma levels of 58 sphingolipid species (including ceramides, monohexosylceramides, sphingomyelins, and sphingosine) were assayed using liquid chromatography tandem mass spectrometry. The study participants (N = 240; 129 Black, 111 White) had a mean age of 43.1 \u00b1 12.0\u00a0y, body mass index (BMI) 29.4 \u00b1 6.23\u00a0kg/m2, fasting plasma glucose 91.4 \u00b1 6.91\u00a0mg/dL, and 2-h plasma glucose 123 \u00b1 26.3\u00a0mg/dL. Several of the 58 SPLs species assayed showed variable associations with insulin sensitivity (r = 0.17-0.35, P = 0.039 - <0.0001) and secretion (r = 0.14-0.27; P = 0.038 - <0.0001). After correction for multiple testing, plasma levels of very-long-chain (VLC) monohexosylceramide C34:0 (r = 0.31 - 0.43, P < 0.0001) and VLC sphingomyelins C28-C34 (r = 0.31-0.35, P = 0.0004 - <0.0001) were significantly associated with insulin sensitivity. Plasma VLC sphingomyelin level were inversely associated with insulin secretion, plasma glucose, BMI, and waist circumference. We conclude that circulating VLC sphingomyelins are associated positively with insulin action and inversely with insulin secretion and adiposity in normoglycemic adults, indicating a possible link to glucoregulation that precedes the development of dysglycemia.\n\nID: 40570250\nTitle: Plasma Sphingolipids in Relation to Glycemia and Glucose Tolerance in People Without Diabetes.\nAbstract: Sphingolipids have been linked to the pathogenesis of type 2 diabetes. To examine the association of plasma sphingolipids with glycemic measures in adults without diabetes. Plasma sphingolipid species (ceramides, monohexosyl ceramides, lactosyl ceramides, sphingomyelins, and sphingosines) were assayed using liquid chromatography tandem mass spectrometry in baseline specimens obtained from participants in the Pathobiology of Prediabetes in a Biracial Cohort study (n = 240) and the Diabetes Prevention Program (n = 280). Based on oral glucose tolerance tests, we identified participants with (1) normal fasting plasma glucose (NFG) (<100\u2005mg/dL) and normal glucose tolerance (NGT) [2-hour plasma glucose (2hPG) < 140\u2005mg/dL]; (2) impaired fasting glucose (IFG; 100-125\u2005mg/dL) with normal 2hPG; (3) impaired glucose tolerance (IGT) (2hPG 140-199\u2005mg/dL with NFG); and (4) IFG and IGT. The participants (63% female; 48% Black, 52% White) had a mean age of 45.5 \u00b1 9.84\u2005years, body mass index (BMI) 32.4 \u00b1 7.24\u2005kg/m2, fasting plasma glucose (FPG) 99.8 \u00b1 10.5\u2005mg/dL, and 2hPG 145 \u00b1 29.4\u2005mg/dL. FPG and 2hPG levels correlated positively with ceramides, sphingomyelins, and sphingosine and inversely with monohexosyl ceramides, lactosyl ceramides, and sphingosine-1 phosphate levels, adjusted for age, sex, race, and BMI. Plasma ceramides, sphingomyelins, and sphingosine increased progressively across participants with NFG-NGT, isolated IGT, and IFG-IGT, whereas the opposite was seen for monohexosyl ceramides, lactosyl ceramides, and sphingosine-1 phosphate levels (ANOVA P < .0001). Circulating levels of major sphingolipid species are significantly associated with glycemia and glucose tolerance, indicating a possible link between sphingolipid metabolism and glucoregulation in people without diabetes.\n\nID: 40535970\nTitle: Fasting the mitochondria to prevent neurodegeneration: the role of ceramides.\nAbstract: Neurodegenerative diseases affect up to 349.2 million individuals worldwide. Preclinical and clinical advances have documented that altered energy homeostasis and mitochondria dysfunction is a hallmark of neurological disorders. Diet-derived ceramides species might target and disrupt mitochondria function leading to defective energy balance and neurodegeneration. Ceramides as bioactive lipid species affect mitochondria function by several mechanism including changes in membrane chemical composition, inhibition of the respiratory chain, ROS overproduction and oxidative stress, and also by activating mitophagy. Promising avenues of intervention has documented that intermittent fasting (IF) is able to benefit and set proper energy metabolism. IF is an eating protocol that involves alternating periods of fasting with periods of eating which modulate ceramide metabolism and mitochondria function in neurons. This review will address the detrimental effect of ceramides on mitochondria membrane composition, respiratory chain, ROS dynamics and mitophagy in brain contributing to neurodegeneration. We will focus on effect of IF on ceramide metabolism as a potential avenue to improve mitochondria function and prevention of neurodegeneration.\n\nID: 40521082\nTitle: Hepatic Lipidomics Unravels the Lipid-Lowering and Anti-Obesity Efficacy of Diacylglycerol Oil: Mechanistic Insights From High-Fat Diet-Induced Obese Mice.\nAbstract: This study employed a multidimensional approach combining clinical and animal experiments to elucidate the lipid-modulating mechanisms of diacylglycerol (DAG). In a 12-week intervention involving obese individuals, fasting serum triglyceride levels were significantly reduced in the DAG group compared to baseline. Within-group reductions in triglycerides and low-density lipoprotein (LDL) cholesterol were more pronounced in the DAG group than in the triacylglycerol (TAG) control group (p\u2009<\u20090.05). In a high-fat diet-induced obese mouse model, DAG significantly lowered serum total cholesterol, LDL levels, visceral fat weight (p\u2009<\u20090.05), attenuated hepatic steatosis, and altered hepatic lipid distribution. Lipidomic profiling revealed that DAG markedly downregulated hepatic triglycerides, ceramides, and monoacylglycerols, while normalizing sterol lipid levels. Pathway analyses based on differential lipids showed that DAG affected hepatic lipid composition mainly by intervening in the glycerophospholipid metabolism pathway. Mechanistically, DAG suppressed the expression of stearoyl-CoA desaturase 1 and fatty acid synthase, while upregulating carnitine palmitoyltransferase 1, thereby enhancing hepatic lipid metabolism through dual regulation: inhibition of synthesis and promotion of catabolism and oxidation. These findings reveal DAG's structure-dependent role in restoring lipid homeostasis and provide a theoretical foundation for functional lipid-based strategies targeting metabolic disorders.\n\nID: 40499231\nTitle: Integrated transcriptomic, metabolomic, and lipidomic analyses reveal a unique lipid profile of regulatory T cells upon activation.\nAbstract: Regulatory T cells (Tregs) exhibit stable FOXP3 expression and regulate the immune response through suppressive activity. Their unique metabolic properties include increased glycolysis and oxidative phosphorylation. We combined transcriptomic, metabolomic, and lipidomic analyses to dissect the metabolic dynamics of Tregs upon activation. Combined metabolomic and lipidomic analyses showed that freshly isolated and activated Tregs had distinct metabolomic and lipidomic properties, respectively. Compared with activated effector T cells (Teffs), activated Tregs contained omega-3 long-chain polyunsaturated fatty acid (PUFA)-rich diglycerides and triglycerides. These were supported by transcriptomics data, showing upregulation of PPAR-alpha and PPAR-gamma. Compared with activated Teffs, activated Tregs exhibited greater ceramide production, consistent with the upregulation of ceramide synthase and sphingomyelin synthase. Confocal microscopy revealed that Tregs, in contrast to Teffs, were enriched in lysosomes and peroxisomes upon activation. Our data confirm the unique metabolic properties of Tregs, especially those characterized by omega-3 long-chain PUFA-rich triglycerides and ceramides, together with enriched lysosomes and peroxisomes, which correspond to metabolic alterations.\n\nID: 40334659\nTitle: Endoplasmic reticulum Nogo drives AgRP neuronal activation and feeding behavior.\nAbstract: Lipid sensing in the hypothalamus contributes to the control of feeding and whole-body metabolism. However, the mechanism responsible for this nutrient-sensing process is ill-defined. Here, we show that Nogo-A, encoded by reticulon 4 (Rtn4) gene and associated with brain development and synaptic plasticity, regulates feeding and energy metabolism by controlling lipid metabolism in Agouti-related protein (AgRP) neurons. Nogo-A expression was upregulated in AgRP neurons of fasted mice and was associated with a significant downregulation of enzymes involved in sphingolipid de novo biosynthesis and the upregulation of key enzymes in intracellular lipid transport and fatty acid oxidation. Deletion of Rtn4 in AgRP neurons reduced body weight, ghrelin-induced AgRP activity and food intake, and fasting-induced AgRP activation, together with an increase in ceramide levels. Finally, high-fat-diet-induced obesity induced a significant downregulation of Rtn4 and increased ceramide levels in AgRP neurons, suggesting a role for Nogo in AgRP dysregulation in obesity. Taken together, our data reveal that Nogo-A drives AgRP neuronal activity and associated feeding behavior by controlling mitochondrial function and cellular lipid metabolism.\n\nID: 40280190\nTitle: Metabotypes are linked to uncontrolled childhood asthma, gut microbiota, and systemic inflammation.\nAbstract: Childhood asthma has been linked to distinct metabolomic profiles. We sought to identify phenotypes (metabotypes) in children with moderate to severe asthma through integrative fecal and serum metabolome analysis. Children from the Systems Pharmacology Approach to Uncontrolled Pediatric Asthma cohort with Global Initiative for Asthma treatment step 3 or higher were recruited. Asthma control was defined by the Asthma Control Test and annual exacerbation history. Targeted metabolomic profiling of feces and serum was performed using liquid chromatography and flow injection electrospray ionization-triple quadrupole mass spectrometry. Similarity network fusion integrated fecal and serum metabolome profiles, followed by spectral clustering. Clusters were analyzed for differences in asthma characteristics, food diaries, fecal microbiota composition, and levels of serum inflammatory markers and blood cells. Integrative fecal and serum metabolome analysis of 92 children with moderate to severe asthma (median age, 11.5 years, 34% female) revealed 3 metabotypes. Metabotype 1 had the lowest percentage of allergic rhinitis, with elevated serum ceramides and triglycerides. Metabotype 2 had higher odds of asthma control, the highest percentage of children with 4 or more months of breast-feeding, reduced sugar intake, lowest levels of blood neutrophils and serum inflammatory markers, and elevated serum acylcarnitines and \u03c9-3 fatty acids. Metabotype 3 included the highest percentage of uncontrolled asthma patients, with decreased serum cholesteryl esters, phosphatidylcholines, and sphingomyelins, elevated fecal amino acids, and reduced fecal microbiota diversity. Metabotypes in children with moderate to severe asthma are linked to asthma control, distinct fecal microbiota, and systemic inflammatory patterns. The findings suggest that metabotyping can be valuable in precision medicine approaches for asthma.\n\nID: 40107296\nTitle: Plasma metabolites associated with endometriosis in adolescents and young adults.\nAbstract: What are the plasma metabolomics profiles associated with endometriosis in adolescents and young adults? Our findings show dysregulation of plasma metabolomic profiles in adolescents and young adults with endometriosis, revealing systemic elevation of fatty acyls and ceramides in endometriosis cases compared to controls. Endometriosis is a gynecologic disease often presenting with severe pelvic pain impacting around 200 million reproductive-aged women worldwide. However, little is known about the pathophysiology and molecular features of endometriosis diagnosed during adolescence and young adulthood. We conducted a cross-sectional analysis including 190 laparoscopically confirmed endometriosis cases and 120 controls who participated in The Women's Health Study: From Adolescence to Adulthood, which enrolled participants from 2012 to 2018. Control participants were females without a diagnosis of endometriosis enrolled from the same clinics as the cases or recruited from the general population. Among the cases, 81 had blood samples collected before and after surgery. Plasma metabolites were measured in blood collected at enrollment using liquid chromatography-tandem mass spectrometry, and a total of 430 known metabolites were evaluated in our analysis. We used linear regression adjusting for age at blood draw, BMI, hormone use, and fasting status at blood draw. Metabolite set enrichment analysis (MSEA) was used to identify metabolite classes. Number of effective tests (NEF) and false discovery rate (FDR) were used for multiple testing correction. The median age was 17\u2009years for endometriosis cases and 22\u2009years for controls. The majority of endometriosis cases had rASRM stage I or II (>95%). We identified 63 plasma metabolites associated with endometriosis (NEF\u2009<\u20090.05). Endometriosis cases had higher levels of plasma metabolites associated with proinflammatory response [e.g. eicosatrienoic acid (\u03b2\u2009=\u20090.61, 95% CI\u2009=\u20090.37, 0.86)], increased oxidative stress response [e.g. xanthine (\u03b2\u2009=\u20090.64, 95% CI\u2009=\u20090.39, 0.88)], and downregulation of metabolites related to apoptosis [glycocholic acid (\u03b2 = -0.80, 95% CI = -1.04, -0.56)]. MSEA revealed increased fatty acyls (FDR\u2009=\u20092.3e-4) and ceramides (FDR\u2009=\u20096.0e-3) and decreased steroids and steroid derivatives (FDR\u2009=\u20091.3e-4) in endometriosis cases compared to controls. When we examined the changes in plasma metabolite profiles before and after surgery among endometriosis cases, 55 endometriosis-associated metabolites significantly changed from before to after surgery. MSEA revealed steroids and steroid derivatives (FDR\u2009=\u20098.1e-4) significantly increased after surgery, while fatty acyls (FDR\u2009=\u20091.2e-4) significantly decreased after surgery. Ceramides did not change from pre- to post-surgery and were elevated in post-surgical blood compared to controls (FDR\u2009=\u20093.9e-3). Our study population mainly consists of self-reported non-Hispanic, white individuals and endometriosis cases with superficial peritoneal lesions only, so the generalizability may be limited. Furthermore, despite our large study population of adolescents and young adults with endometriosis, sample size was limited to conduct detailed stratified analyses of plasma metabolomic profiles, especially by post-surgical pelvic pain outcomes. Our study includes the utilization of state-of-the-art metabolomics technology with high reproducibility to comprehensively investigate the metabolites that were associated with endometriosis diagnosed in adolescents and young adults. Our results suggest a positive impact of endometriosis-related surgery for some, but not all, on systemic metabolic dysregulation in young patients with endometriosis. These results warrant further investigation on whether and how persistent systemic changes despite treatment may lead to long-term chronic disease risk among those diagnosed with endometriosis.

However, its underlying mechanism and physiological significance are not fully understood. Here we demonstrate that carbohydrate response element-binding protein (ChREBP) mediates lipid metabolic remodeling and promotes progressive triglyceride accumulation against metabolic injury in adult FBP1-deficient liver. Inducible liver-specific deletion of Fbp1 gene caused progressive hepatomegaly and hepatic steatosis, with a marked increase in hepatic de novo lipogenesis (DNL) as well as a decrease in plasma \u03b2-hydroxybutyrate levels. Notably, FBP1 deficiency resulted in a persistent activation of ChREBP and its target genes involved in glycolysis, lipogenesis, and fatty acid oxidation, even under fasting conditions. Furthermore, liver-specific ChREBP disruption could markedly restore the phenotypes of enhanced DNL and triglyceride accumulation in FBP1-deficient liver but exacerbated its hepatomegaly and liver injury, which was associated with remarkable energy deficit, impaired mammalian target of rapamycin (mTOR) activation, and increased oxidative stress. Furthermore, metabolomics analysis revealed a robust elevation of phosphoenolpyruvate, phosphoglycerates, phospholipids, and ceramides caused by ChREBP deletion in FBP1-deficient liver. Put together, these results suggest that overactivation of ChREBP pathway mediates liver metabolic remodeling in the absence of FBP1, which contributes to the pathogenesis of progressive hepatic steatosis and provides a protection against liver injury. Thus, our findings point to a beneficial role of ChREBP in metabolic remodeling in the context of excessive gluconeogenic intermediates.NEW & NOTEWORTHY FBP1 deficiency in adulthood causes progressive hepatic steatosis due to the overactivation of ChREBP pathway, which enhances lipid synthesis and inhibits fat oxidation. ChREBP-mediated metabolic remodeling protects against liver injury caused by energy deficit and oxidative stress in FBP1-deficient liver.\n\nID: 39911696\nTitle: Reshaping lipid metabolism with long-term alternate day feeding in type 2 diabetes mice.\nAbstract: Strategies to improve metabolic health include calorie restriction, time restricted eating and fasting several days per week or month. These approaches have demonstrated benefits for individuals experiencing obesity, metabolic syndrome, and prediabetes. However, their impact on established diabetes remains incompletely studied. The chronicity of type 2 diabetes (T2D) requires that interventions must be undertaken for extended periods of time, typically the entire lifetime of the individual. In this study, we examined the impact of intermittent fasting (IF), with an every-other-day protocol for a duration of 6 months in a murine model of T2D, the db/db (D) mouse on metabolism and liver steatosis. We compared D-IF mice with diabetic ad-libitum (AL; D-AL), control-IF (C-IF) and control-AL (C-AL) cohorts. We demonstrated using lipidomic, microbiome, metabolomic and liver transcriptomic studies that chronic IF improved carbohydrate utilization and glucose homeostasis without weight loss and reduced white adipose tissue inflammation and significantly impacted lipid metabolism in the liver. Microbiome studies and predicted functional analysis of gut microbiota showed that IF increased beneficial bacteria involved in sphingolipid (SL) metabolism. The metabolomic studies showed that oxidation of lipid species and ceramide levels were reduced in D-IF compared to D-AL. The liver lipidomic analysis and liver microarray confirmed a reduction in overall lipid content in D-IF mice compared to D-AL mice, especially in the feeding state as well as an overall reduction in oxidized lipids and ceramides. These studies support that long-term IF can improve glucose homeostasis and dramatically altered lipid metabolism in the absence of weight loss.\n\nID: 39633874\nTitle: Metabolic signatures of combined exercise and fasting: an expanded perspective on previous telomere length findings.\nAbstract: Aging is a complex process marked by a gradual decline in physiological function and increased susceptibility to diseases. Telomere length is frequently regarded as one of the primary biomarkers of aging. Metabolic profiles are key features in longevity and have been associated with both age and age-related diseases. We previously reported an increase in the telomere length in healthy female subjects when Ramadan fasting was combined with physical training. This study aims to characterize the metabolic signature differentiating the combined effects of exercise and fasting from exercise alone and explore the correlations with the previously reported telomere length changes. Twenty-nine young, non-obese, and healthy female subjects were previously randomized into two groups: one group followed a 4-week exercise program, while the other group followed the same 4-week exercise program but also fasted during Ramadan. Metabolic profiles were assessed pre- and post-intervention using untargeted metabolomics. Our results showed a significant decrease in many lipid metabolites in the exercise-while-fasting group, particularly ceramides. Our study sheds light on the dynamic changes in lipid metabolism and its potential role in inflammation and age-related diseases, and contributes to the broader understanding of how lifestyle factors can influence cellular aging and metabolic health.\n\nID: 39530793\nTitle: High-coverage targeted lipidomics revealed a novel serum lipid dysregulation profile in adult growth hormone deficiency.\nAbstract: Patients with adult growth hormone deficiency (AGHD) are at an increased risk of metabolic syndrome. Despite extensive research efforts in recent decades, the lipid metabolism pattern of AGHD has yet to be thoroughly characterized. In this study, we used lipidomics analysis of fasting serum samples from 30 AGHD patients with intracranial germ cell tumors (iGCTs) and 30 age-, gender- and body mass index (BMI)-matched healthy controls to investigate the serum lipidomic pattern of AGHD patients with iGCTs. We meticulously quantified 534 serum lipids from 29 classes using high-coverage targeted lipidomics technology in conjunction with a robust bioinformatics pipeline. Our results revealed an AGHD-specific dynamic change in the serum lipidomic profile, manifested by higher overall levels of many lipid subclasses, including triacylglycerols (TAGs), diacylglycerols (DAGs), phosphatidylglycerols, phosphatidylethanolamines (PE), phosphatidylcholines (PC), phosphatidylinositols, ceramides and bis(monoacylglycerol)phosphates, than in healthy controls and a distinct lower level for alkyl PE (PE-O) and alkyl PC (PC-O). AGHD individuals with nonalcoholic fatty liver disease showed specific changes in higher TAG and DAG subclass levels. Alterations in lipid profiles may contribute to metabolic dysregulation in AGHD patients. TAGs, PCs and PE fatty acids positively correlated with BMI, fasting insulin, insulin resistance index and adverse lipid parameters. In contrast, ether-linked PE-O, PC-O and LysoPE-O showed a negative correlation. This study has significantly expanded the current understanding of lipid dysregulation in AGHD patients with iGCT. These findings can potentially guide future research and development of monitoring and intervention strategies.\n\nID: 39428081\nTitle: Age-dependent changes in visceral adiposity are associated with decreased plasma levels of DHEA-S in sigma-1 receptor knockout male mice.\nAbstract: The sigma-1 receptor (S1R) is involved in intracellular lipid synthesis and transport. Recent studies have shown that its genetic inactivation impairs adipogenic differentiation in vitro. This study investigated the role of S1R in adipose tissue physiology and metabolic health using adult and old WT and S1R KO mice. Visceral fat mass was increased in adult, but not old S1R-KO male mice compared to that of WT mice, despite having similar body weights, food intake, and energy expenditure. The average adipocyte size was 64\u00a0% larger in adult KO mice than in adult WT mice. Adult S1R-KO mice showed reduced plasma dehydroepiandrosterone sulfate (DHEA-S) and elevated fasting plasma leptin concentrations. Lipidomic analysis revealed alterations in plasma metabolite concentrations, particularly reduced levels of sphingomyelins, ceramides, phosphatidylcholines, lysophosphatidylcholines, and cholesteryl esters in adult mice. Decreased expression of Ppar\u03b3, Adipoq, and Atgl was detected in visceral white adipose tissue (vWAT) isolated from adult KO mice. Additionally, Fabp4 and Adipoq expression levels were significantly lower in KO adipose-derived stromal cells than in WT adipose-derived stromal cells. A fivefold increase in the mitochondrial fatty acid oxidation rate and a 43\u00a0% increase in electron transfer coupling capacity were detected in adult S1R-KO vWAT. In summary, our investigation revealed an age-dependent association between increased visceral adiposity and decreased plasma levels of DHEA-S in S1R-deficient male mice. These findings underscore the potential role of S1R in regulating metabolic processes in adipose tissue and suggest that DHEA-S is a potential mediator of adiposity changes in the absence of S1R.\n\nID: 39304782\nTitle: Lipid profiling identifies modifiable signatures of cardiometabolic risk in children and adolescents with obesity.\nAbstract: Pediatric obesity is a progressive, chronic disease that can lead to serious cardiometabolic complications. Here we investigated the peripheral lipidome in 958 children and adolescents with overweight or obesity and 373 with normal weight, in a cross-sectional study. We also implemented a family-based, personalized program to assess the effects of obesity management on 186 children and adolescents in a clinical setting. Using mass spectrometry-based lipidomics, we report an increase in ceramides, alongside a decrease in lysophospholipids and omega-3 fatty acids with obesity metabolism. Ceramides, phosphatidylethanolamines and phosphatidylinositols were associated with insulin resistance and cardiometabolic risk, whereas sphingomyelins showed inverse associations. Additionally, a panel of three lipids predicted hepatic steatosis as effectively as liver enzymes. Lipids partially mediated the association between obesity and cardiometabolic traits. The nonpharmacological management reduced levels of ceramides, phospholipids and triglycerides, indicating that lowering the degree of obesity could partially restore a healthy lipid profile in children and adolescents.\n\nID: 39182617\nTitle: Deep serum lipidomics identifies evaluative and predictive biomarkers for individualized glycemic responses following low-energy diet-induced weight loss: a PREVention of diabetes through lifestyle Intervention and population studies in Europe and around the World (PREVIEW) substudy.\nAbstract: Weight loss through lifestyle interventions, notably low-energy diets, offers glycemic benefits in populations with overweight-associated prediabetes. However, >50% of these individuals fail to achieve normoglycemia after weight loss. Circulating lipids hold potential for evaluating dietary impacts and predicting diabetes risk. This study sought to identify serum lipids that could serve as evaluative or predictive biomarkers for individual glycemic changes following diet-induced weight loss. We studied 104 participants with overweight-associated prediabetes, who lost \u22658% weight via a low-energy diet over 8 wk. High-coverage lipidomics was conducted in serum samples before and after the dietary intervention. The lipidomic recalibration was assessed using differential lipid abundance comparisons and partial least squares discriminant analyses. Associations between lipid changes and clinical characteristics were determined by Spearman correlation and Bootstrap Forest of ensemble machine learning model. Baseline lipids, predictive of glycemic parameters changes postweight loss, were assessed using Bootstrap Forest analyses. We quantified 439 serum lipid species and 9 related organic acids. Dietary intervention significantly reduced diacylglycerols, ceramides, lysophospholipids, and ether-linked phosphatidylethanolamine. In contrast, acylcarnitines, short-chain fatty acids, organic acids, and ether-linked phosphatidylcholine increased significantly. Changes in certain lipid species (e.g., saturated and monounsaturated fatty acid-containing glycerolipids, sphingadienine-based very long-chain sphingolipids, and organic acids) were closely associated with clinical glycemic parameters. Six baseline bioactive sphingolipids primarily predicted changes in fasting plasma glucose. In addition, a number of baseline lipid species, mainly diacylglycerols and triglycerides, were predictive of clinical changes in hemoglobin A1c, insulin and homeostasis model assessment of insulin resistance. Newly discovered serum lipidomic alterations and the associated changes in lipid-clinical variables suggest broad metabolic reprogramming related to diet-mediated glycemic control. Novel lipid predictors of glycemic outcomes could facilitate early stratification of individuals with prediabetes who are metabolically less responsive to weight loss, enabling more tailored intervention strategies beyond 1-size-fits-all lifestyle modification advice. The PREVIEW lifestyle intervention study was registered at clinicaltrials.gov as NCT01777893 (https://clinicaltrials.gov/study/NCT01777893).\n\nID: 39100221\nTitle: Impact of Lipids on Insulin Resistance: Insights from Human and Animal Studies.\nAbstract: Insulin resistance (IR) is a complex pathological condition central to metabolic diseases such as type 2 diabetes mellitus (T2DM), cardiovascular disease, non-alcoholic fatty liver disease, and polycystic ovary syndrome (PCOS). This review evaluates the impact of lipids on insulin resistance (IR) by analyzing findings from human and animal studies. The articles were searched on the PubMed database using two keywords: (1) \"Role of Lipids AND Insulin Resistance AND Humans\" and (2) \"Role of Lipids AND Insulin Resistance AND Animal Models\". Studies in humans revealed that elevated levels of free fatty acids (FFAs) and triglycerides (TGs) are closely associated with reduced insulin sensitivity, and interventions like metformin and omega-3 fatty acids show potential benefits. In animal models, high-fat diets disrupt insulin signaling and increase inflammation, with lipid mediators such as diacylglycerol (DAG) and ceramides playing significant roles. DAG activates protein kinase C, which eventually impairs insulin signaling, while ceramides inhibit Akt/PKB, further contributing to IR. Understanding these mechanisms is crucial for developing effective prevention and treatment strategies for IR-related diseases.\n\nID: 38976482\nTitle: GLP-1 Receptor Agonist Treatment Improves Fasting and Postprandial Lipidomic Profiles Independently of Diabetes and Weight Loss.\nAbstract: Treatment with glucagon-like peptide 1 receptor agonists reduces liver steatosis and cardiometabolic risk (CMR). Few data are available on lipid metabolism, and no information is available on the postprandial lipidomic profile. Thus, we investigated how exenatide treatment changes lipid metabolism and composition during fasting and after a mixed-meal tolerance test (MMTT) in adults with severe obesity without diabetes. Thirty individuals (26 females and 4 males, 30-60 years old, BMI >40 kg/m2, HbA1c 5.76%) were assigned (1:1) to diet with exenatide 10 \u03bcg twice daily treatment (n = 15) or without treatment as control (n = 15) for 3 months. Fasting and postprandial lipidomic profile (by liquid chromatography quadrupole time-of-flight mass spectrometry) and fatty acid metabolism (following a 6-h MMTT/tracer study) and composition (by gas chromatography-mass spectrometry) were evaluated before and after treatment. Both groups had slight weight loss (-5.5% vs. -1.9%, exenatide vs. control; P = 0.052). During fasting, exenatide, compared with control, reduced some ceramides (CERs) and lysophosphatidylcholines (LPCs) previously associated with CMR, while relatively increasing unsaturated phospholipid species (phosphatidylcholine [PC], LPC) with protective effects on CMR, although concentrations of total lipid species were unchanged. During MMTT, both groups showed suppressed lipolysis equal to baseline, but exenatide significantly lowered free fatty acid clearance and postprandial triacyclglycerol (TAG) concentrations, particularly saturated TAGs with 44-54 carbons. Exenatide also reduced some postprandial CERs, PCs, and LPCs previously linked to CMR. These changes in lipidomic profile remained statistically significant after adjusting for weight loss. Exenatide improved fasting and postprandial lipidomic profiles associated with CMR mainly by reducing saturated postprandial TAGs and CERs independently of weight loss and diabetes.\n\nID: 42564199\nTitle: Euonymus alatus in diabetes: a review of phytochemistry, pharmacokinetics, and anti-diabetic mechanisms.\nAbstract: Euonymus alatus: (EA), a traditional Chinese botanical drug documented in the Shennong Ben Cao Jing, has been investigated for its potential anti-diabetic effects. This review systematically examines the phytochemistry, pharmacokinetics, and anti-diabetic mechanisms of this botanical drug. Over 230 metabolites, including flavonoids, triterpenoids, and lignans, have been identified from EA. Pharmacokinetic studies remain limited; computational predictions suggest that some metabolites may exhibit oral bioavailability, but classical pharmacokinetic parameters have not been experimentally determined for any EA metabolite. Mechanistic studies demonstrate that EA exerts anti-diabetic effects through multiple experimentally validated pathways: (i) inhibiting alpha-glucosidase activity to delay intestinal glucose absorption; (ii) activating the peroxisome proliferator-activated receptor gamma and phosphatidylinositol 3-kinase/protein kinase B signaling pathways to ameliorate insulin resistance; (iii) modulating gut microbiota composition and increasing short-chain fatty acid production; (iv) suppressing the advanced glycation end products-receptor for advanced glycation end products axis along with the nuclear factor kappa B and mitogen-activated protein kinase inflammatory pathways to alleviate oxidative stress and inflammatory responses; and (v) regulating diacylglycerol acyltransferase activity to improve lipid metabolism. Preclinical studies indicate that EA reduces blood glucose and improves markers of diabetic nephropathy and retinopathy. Clinical studies of EA-containing formulations report reductions in fasting blood glucose and urinary protein. However, the clinical evidence remains limited by small sample sizes, lack of rigorous controls, and multi-botanical drug compositions that preclude attribution of effects to individual components. This review provides a critical synthesis of current evidence and identifies priorities for future investigation.\n\nID: 42563655\nTitle: Serum lipids and outcomes of COVID-19 patients admitted to a tertiary hospital in Johannesburg, South Africa.\nAbstract: Cardiometabolic disorders contribute significantly to global cardiovascular disease risk. COVID-19 can exacerbate underlying vascular and metabolic disturbances through immune and inflammatory pathways. Lipoprotein abnormalities may influence disease susceptibility and outcomes, as lipoproteins play key roles in viral entry, inflammation and immune regulation. These markers may therefore serve as potential biomarkers for predicting outcomes, yet data from African populations remain limited. To determine the association between admission lipid profiles and adverse clinical outcomes in hospitalised COVID-19 patients within a resource-constrained setting, in a predominantly black African population. This retrospective observational study was conducted at Charlotte Maxeke Johannesburg Academic Hospital between 6 March and 31 August 2020. Adults aged \u226518 years with confirmed SARS-CoV-2 infection who had admission lipid profiles were included. The association between lipid parameters and adverse clinical outcomes, including intensive care unit (ICU) admission, mechanical ventilation, and in-hospital mortality, were determined by multivariable logistic regression analysis. Correlation analyses examined associations between lipids and inflammatory markers. Among 305 patients (mean (standard deviation) age 53 (13.8) years; 77% black ethnicity), non-survivors had significantly lower low-density lipoprotein cholesterol (LDL-C) and total cholesterol (TC), and higher fasting plasma glucose and inflammatory markers. Both LDL-C and TC were inversely correlated with procalcitonin (\u03c1=-0.44, 95% confidence interval (CI) -0.65 - -0.23, p=0.001; (\u03c1=-0.28, CI-0.52 - -0.05), p=0.03, respectively). Triglyceride (TG) levels were higher in ICU patients (p=0.01), and significantly correlated with an increasing white cell count (\u03c1=0.31, CI 0.09 - 0.53, p=0.01), neutrophil-to-lymphocyte ratio (\u03c1=0.27, CI 0.01 - 0.54, p=0.04) and fasting plasma glucose (\u03c1=0.39, CI 0.14 - 0.64, p=0.03), but were not independently predictive of mortality. High-density lipoprotein cholesterol was lower in ICU-admitted patients and inversely correlated with ferritin, but it was also not significantly associated with mortality. Lower LDL-C was an independent predictor of ICU admission (odds ratio (OR) 0.69, CI 0.50 - 0.96, p=0.03 ), mechanical ventilation (OR 0.55, CI 0.35 - 0.86, p=0.009 ) and mortality (OR 0.66, CI 0.48 - 0.91, p=0.01), with an LDL-C <2.2 mmol/L associated with increased mortality(area under curve 0.62, CI 0.55 - 0.69), as shown in receiver operating characteristic analysis. Non-survivors had significantly higher inflammatory markers compared with survivors, and low LDL-C and TC were independently associated with adverse outcomes. LDL-C also predicted ICU admission, mechanical ventilation and mortality, highlighting the link between lipid metabolism and immune response. These findings emphasise the need for further prospective studies to evaluate the utility of these markers as accessible prognostic tools in low- and middle-income countries.\n\nID: 42551759\nTitle: Fatty acids and breast cancer: Epidemiology, subtype-specific metabolism, immune regulation, and clinical translation.\nAbstract: Fatty acids (FAs) are bioactive dietary and metabolic molecules that participate in membrane architecture, energy homeostasis, inflammatory signaling, gene regulation and immune function, all of which intersect with breast cancer (BC) risk, progression and treatment response. In this narrative review we integrate epidemiological, clinical, translational and mechanistic evidence on the role of FAs in BC. Saturated, monounsaturated, trans- and polyunsaturated FAs (PUFAs) are treated as distinct biological exposures rather than interchangeable measures of total fat intake. Similarly, evidence from dietary assessment, circulating biomarkers, erythrocyte membrane composition, adipose tissue stores and tumor lipid signatures is interpreted separately, because each captures exposure and biology at a different level. BC subtypes differ in FA synthesis, uptake, oxidation, storage and remodeling: luminal tumors are frequently linked to hormone-regulated lipogenesis, human epidermal growth factor receptor 2 (HER2)-positive tumors to growth-factor-driven lipid metabolism, and triple-negative tumors to exogenous FA uptake, inflammatory lipid mediators and ferroptosis-related vulnerabilities. FA-derived mediators also shape immune-cell polarization, cytokine signaling and the tumor microenvironment, and dietary FAs may reshape the gut microbiota; the fiber-derived short-chain FAs it produces, distinct from dietary FAs, likewise help regulate immune and inflammatory tone. Clinical data suggest possible roles for fat-quality modification and selected n-3 PUFA interventions, but findings are heterogeneous and not yet sufficient to support routine biomarker-guided precision onco-nutrition. Candidate biomarkers, such as erythrocyte n-6:n-3 composition, require prospective validation before clinical implementation. FA biology thus represents a modifiable but complex axis in BC prevention, tumor biology and supportive care.\n\nID: 42555877\nTitle: Shatavarin IV from Asparagus curillus roots exhibits antidiabetic activity in STZ-induced rats.\nAbstract: The present study aimed to isolate and evaluate the antidiabetic potential of shatavarin IV, a major steroidal saponin from the ethanolic root extract of Asparagus curillus Buch.-Ham. ex Roxb. Shatavarin IV was isolated and characterised using chromatographic and spectroscopic techniques. Its antidiabetic activity was assessed in STZ-induced diabetic rats by monitoring blood glucose, insulin, glycated haemoglobin, and lipid profile parameters. Treatment with shatavarin IV, particularly at 400\u2009\u03bcg/kg (p.o., b.w.), significantly reduced fasting blood glucose from 265.80 to 119.58\u2009mg/dL, improved insulin levels from 13.99 to 21.69 mIU/mL, and decreased HbA1c from 11.52 to 5.91%. Additionally, it ameliorated diabetes-induced dyslipidemia by lowering total cholesterol, triglycerides, LDL, VLDL, and atherogenic index while increasing HDL. These effects are likely mediated by the steroidal saponin nature of shatavarin IV, which modulates glucose and lipid metabolism. These findings identify shatavarin IV as a key bioactive constituent of A. curillus with antidiabetic and hypolipidemic potential.\n\nID: 42549049\nTitle: Empagliflozin in the Absence of Diabetes: A Systematic Review of Its Anthropometric and Metabolic Effects in Humans and Animals.\nAbstract: Obesity raises metabolic and cardiovascular risk and represents a major public health challenge. The sodium-glucose cotransport-2 inhibitor empagliflozin (EMPA) may improve metabolic parameters beyond glycemic control. This systematic review critically evaluated the effects of EMPA on anthropometric and metabolic outcomes in overweight or obese subjects without diabetes and identified key areas for future research. This systematic review included studies identified through searches of five databases (Scopus, Web of Science, PubMed, Google Scholar, and the Cochrane Library) from January 2023 to May 2026. Following duplicate removal and PRISMA-guided screening, 27 studies were included (7 randomized controlled trials and 20 animal studies). Studies were excluded if they involved diabetic populations, lacked appropriate comparator groups, or did not meet predefined eligibility criteria. The Cochrane and SYRCLE tools were used to assess the quality of human and animal evidence, respectively. Animal studies primarily used EMPA doses of 8-30\u2009mg/kg/day, whereas human trials employed fixed clinical doses of 10-12.5\u2009mg daily. In human investigations, EMPA significantly lowered body weight with notable improvements in fasting glucose. Preclinical studies largely supported these findings and additionally demonstrated improvements in hepatic steatosis, lipid metabolism, and inflammatory markers. Proposed mechanisms included modulation of FGF21 signaling, hepatic PDK4 expression, hypothalamic neuropeptides, NF-\u03baB activity, mitochondrial function, and gut microbiome composition. Even in the absence of diabetes, EMPA shows potential for improving anthropometric and metabolic indices. However, clinical evidence remains limited and further human trials are needed to confirm its long-term safety, efficacy, and underlying molecular mechanisms.\n\nID: 42548999\nTitle: Paeoniflorin and NAFLD: A Systematic Review and Meta-Analysis of Animal Studies With Mechanistic Insights.\nAbstract: Nonalcoholic fatty liver disease (NAFLD) is a major metabolic liver disorder with limited pharmacological options. Paeoniflorin (PF), a bioactive compound from Paeonia lactiflora, has shown hepatometabolic effects in experimental studies, but its overall efficacy in NAFLD models remains unclear. We searched PubMed, Embase, Web of Science, the Cochrane Library, CNKI, Wanfang, VIP, and CBM from inception to January 2026 for controlled animal studies evaluating PF in diet-induced NAFLD models. Two reviewers independently performed study selection, data extraction, and risk-of-bias assessment using SYRCLE's tool. Weighted mean differences or standardized mean differences with 95% confidence intervals were pooled using random-effects models. Ten studies were included, all using diet-induced models. PF treatment was associated with improvements in lipid metabolism, liver injury, glucose homeostasis, inflammation, and oxidative stress, including reductions in total cholesterol, triglycerides, low-density lipoprotein cholesterol, alanine aminotransferase, aspartate aminotransferase, body weight, fasting blood glucose, insulin resistance indices, tumor necrosis factor-\u03b1, and malondialdehyde, together with increased superoxide dismutase activity. High-density lipoprotein cholesterol showed no consistent improvement. Mechanistic findings suggested that PF may activate AMP-activated protein kinase, inhibit sterol regulatory element-binding protein-1c/fatty acid synthase-mediated lipogenesis, and modulate inflammatory and oxidative-stress pathways. However, substantial heterogeneity and incomplete reporting of randomization, allocation concealment, and blinding limited confidence in the evidence. PF showed promising preclinical effects in NAFLD, but further well-designed animal studies and clinical investigations are needed to clarify dose-response relationships, safety, and translational relevance.\n\nID: 42544905\nTitle: Effects of vitamin D supplementation on insulin resistance and lipid metabolic profiles in women with gestational diabetes mellitus: A randomized controlled trial.\nAbstract: Gestational diabetes mellitus (GDM) commonly presents as insulin resistance and altered lipid metabolism, with evidence linking vitamin D deficiency to its pathogenesis. In this randomized, double-blind, placebo-controlled trial, 120 pregnant women diagnosed with GDM were assigned to receive either vitamin D3 supplements (2000 IU/day) or a placebo for 3 months. Serum vitamin D status, glycemic control parameters, and lipid profiles were evaluated pre- and post-intervention, adjusting for dietary and exercise confounders. After the 3-month intervention, serum 25-hydroxyvitamin D levels in the vitamin D group were significantly higher than those in the placebo group. Vitamin D supplementation effectively reduced fasting plasma glucose, fasting insulin, and HOMA-IR scores. Simultaneously, it significantly decreased triglycerides and LDL-C levels while increasing HDL-C. Total cholesterol levels showed no statistically significant difference between the two groups. Supplementation with 2000 IU vitamin D per day for 3 months yields significant improvements in glucose homeostasis and lipid metabolism in the GDM population. Vitamin D holds promise as an effective auxiliary treatment to enhance maternal metabolic health. Le diab\u00e8te gestationnel (DG) se manifeste fr\u00e9quemment par une r\u00e9sistance \u00e0 l\u2019insuline et des anomalies du m\u00e9tabolisme lipidique, avec des donn\u00e9es sugg\u00e9rant un lien entre la carence en vitamine D et sa physiopathologie. Dans cet essai randomis\u00e9, en double aveugle et contr\u00f4l\u00e9 par placebo, 120 femmes enceintes diagnostiqu\u00e9es avec un diab\u00e8te gestationnel ont \u00e9t\u00e9 r\u00e9parties pour recevoir soit une suppl\u00e9mentation en vitamine D3 (2000 UI/jour), soit un placebo pendant 3 mois. Le statut en vitamine D s\u00e9rique, les param\u00e8tres de contr\u00f4le glyc\u00e9mique et les profils lipidiques ont \u00e9t\u00e9 \u00e9valu\u00e9s avant et apr\u00e8s l\u2019intervention, en ajustant les facteurs de confusion li\u00e9s \u00e0 l\u2019alimentation et \u00e0 l\u2019activit\u00e9 physique. Apr\u00e8s 3 mois d\u2019intervention, les concentrations s\u00e9riques de 25-hydroxyvitamine D dans le groupe vitamine D \u00e9taient significativement plus \u00e9lev\u00e9es que dans le groupe placebo. La suppl\u00e9mentation en vitamine D a permis de r\u00e9duire efficacement la glyc\u00e9mie \u00e0 jeun, l\u2019insuline \u00e0 jeun et les scores HOMA-IR.

Emerging evidence implicates lipid dysregulation in neurodegeneration, but its extent across FTLD subtypes and how it compares to AD are unclear. Here, we performed integrated lipidomic and proteomic analyses of matched frontal (disease-vulnerable) and occipital (relatively spared) post-mortem cortices from individuals with genetic and sporadic FTLD-TDP, FTLD-tau (Pick's disease, PiD), AD, and controls. FTLD and AD exhibited convergent lipid alterations, including reduced levels of cardiolipins and phosphatidylethanolamines, alongside increased gangliosides, diacylglycerols, cholesterol esters, acylcarnitines, and coenzyme Q, with generally greater changes in FTLD frontal cortex. FTLD displayed additional alterations, including reductions in bis(monoacylglycerol)phosphate, ceramides, phosphatidylserines, phosphatidylinositols, and sulfatides. These lipid changes were accompanied by proteomic alterations involving lysosomal proteins, phospholipases, phospholipid remodeling enzymes, and fatty acid oxidation pathways. Although lipidomic and proteomic signatures were broadly shared across FTLD subtypes, GRN associated FTLD-TDP and PiD showed the most extensive alterations. Triglycerides were selectively reduced in PiD in association with decreased DGAT1 expression, whereas cholesterol esters were elevated across all subtypes except C9orf72 associated FTLD-TDP. These findings identify shared disruptions in lipid homeostasis and lysosomal lipid metabolism across FTLD and AD, highlighting convergent metabolic pathways underlying neurodegeneration.\n\nID: 42538401\nTitle: Intermittent fasting: Impact, mechanisms and cautions across medical and lifestyle domains.\nAbstract: Intermittent fasting (IF) has emerged as a promising dietary approach with prospective advantages for clinical as well as non-clinical applications. Research indicates that IF enhances insulin sensitivity, facilitates weight reduction and stimulates cellular repair pathways, including autophagy. Physiological adaptations to fasting are reflected in favorable alterations in biomarkers and metabolic processes. This review examines the current evidence on IF by analyzing studies retrieved through schematic searches of the MEDLINE via PubMed database, Embase and ScienceDirect using specific keyword combinations. It focuses on commonly practiced regimens- Time-restricted eating (TRE) (16/8 method), Alternate-day fasting (ADF), the 5:2 intermittent energy-restriction diet and One meal a day (OMAD) approaches and explores their effects on cardiovascular function, metabolic regulation, cognitive performance and longevity. Various IF regimens including the TRE (16/8 method), ADF, the 5:2 diet and OMAD approaches are discussed in relation to their effects on cardiovascular health, cognitive function, metabolic regulation, aging and longevity. While most finding highlight significant health benefits, inconsistencies and methodological limitations are also reported. Mechanistically, IF orchestrates a coordinated metabolic response through modulation of key nutrient sensing pathway such as AMP activated protein kinase (AMPK), mechanistic target of rapamycin (mTOR) and unc-51-like kinase 1 (ULK1). These cascades interact with Sirtuins (SIRT1/3), peroxisome proliferator activated receptor gamma coactivator-1\u03b1 (PGC-1\u03b1) and the transcription factor EB (TFEB) to regulate autophagy, mitochondrial biogenesis, oxidative stress defense and cellular repair. Clinically, these molecular events underpin improvements in glycaemic control, lipid metabolism and inflammatory balance, supporting the therapeutic potential of IF for cardiometabolic disorders, neuroprotection and healthy aging.\n\nID: 42528620\nTitle: Effects of high-intensity interval training and moderate-intensity continuous training on body composition and glucose and lipid metabolism in college students: a systematic review and meta-analysis.\nAbstract: This study systematically evaluated high-intensity interval training (HIIT) versus moderate-intensity continuous training (MICT) for body composition and glucose and lipid metabolism markers in college students. This PRISMA 2020-based systematic review searched PubMed, Cochrane Library, Web of Science, Embase, China National Knowledge Infrastructure (CNKI), and VIP Database (VIP) from inception to March 10, 2026. Restricted maximum likelihood (REML) random-effects models pooled mean differences (MDs) with 95% confidence intervals (CIs), and heterogeneity was assessed using Cochran's Q and I2. Subgroup, meta-regression, sensitivity, publication bias, RoB 2.0, and GRADE analyses were conducted. A total of 20 randomized controlled trials (RCTs) involving 745 college students were included, with 377 in HIIT and 368 in MICT. Compared with MICT, HIIT significantly reduced body weight (MD = -1.23\u00a0kg, 95% CI -1.94 to -0.52, P\u00a0=\u00a00.002), body fat percentage (MD = -1.21%, 95% CI -2.12 to -0.30, P\u00a0=\u00a00.013), waist-to-hip ratio (MD = -0.01, 95% CI -0.02 to -0.00, P\u00a0=\u00a00.014), waist circumference (MD = -1.33\u00a0cm, 95% CI -2.40 to -0.26, P\u00a0=\u00a00.023), and fat mass (MD = -0.99\u00a0kg, 95% CI -1.66 to -0.33, P\u00a0=\u00a00.010). No significant differences were found for body mass index (BMI), hip circumference, muscle mass, total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), fasting blood glucose (FBG), or fasting insulin (FINS). Subgroup analyses suggested sex might influence body weight and BMI effects, but most analyses showed no clear moderation. Meta-regression detected no significant moderation by duration or weekly HIIT volume. Evidence for body composition outcomes was mostly moderate, low, or very low; evidence for glucose and lipid metabolism outcomes was very low. Compared with MICT, HIIT may provide greater benefits for selected body composition measures in college students, particularly body weight, body fat percentage, waist circumference, waist-to-hip ratio, and fat mass. However, HIIT did not consistently improve routine glucose and lipid metabolism markers. Given the limited evidence quality, small number of studies, and uncertain moderator findings from subgroup and meta-regression analyses, larger randomized controlled trials with standardized protocols are needed. https://www.crd.york.ac.uk/PROSPERO/, identifier CRD420261396573.\n\nID: 42522304\nTitle: Nutritional Adjuvants in Diabetes: Biotin and Chromium Picolinate as Emerging Therapeutic Agents.\nAbstract: Insulin resistance and type 2 diabetes mellitus (T2DM) are serious worldwide health issues linked to dyslipidaemia, oxidative stress, impaired glucose metabolism, and persistent inflammation. Although their clinical significance is still unknown, micronutrients like chromium and biotin are thought to affect insulin signalling, glucose homeostasis, and lipid metabolism. The purpose of this review is to compile the preclinical, clinical, and epidemiological data that is currently available regarding the individual and combined effects of chromium and biotin on metabolic outcomes, insulin sensitivity, and glycaemic control. Using databases like PubMed, Scopus, and Google Scholar, a thorough search of narrative literature was carried out. Included were pertinent experimental, clinical, and review studies evaluating the use of chromium and/or biotin supplements in diseases like metabolic syndrome, insulin resistance, and type 2 diabetes. With a focus on study design, dosage, duration, mechanistic pathways, and reported metabolic outcomes, the evidence was qualitatively examined. Preclinical research repeatedly shows that biotin and chromium improve oxidative stress markers, lipid profiles, insulin sensitivity, and glucose tolerance. Increased GLUT-4 translocation, AMPK activation, insulin signalling pathway modulation (IRS-1/PI3K/Akt), and biotin-dependent enzyme regulation are some of the mechanisms that mediate these effects. Particularly in those with poor glycaemic control or micronutrient deficiencies, clinical trials show modest but significant improvements in fasting blood glucose, HbA1c levels, insulin resistance indices, and lipid parameters. Glycaemic control, dyslipidaemia, oxidative stress, and cardiovascular risk markers all seem to improve with combined supplementation. Additionally, epidemiological data point to a negative correlation between dietary chromium consumption and the risk of T2DM. The results demonstrate the complementary functions of biotin and chromium in controlling the metabolism of fats and carbohydrates. When taken together, they may provide greater metabolic advantages than when taken separately. However, the generalisability of findings is constrained by variations in study design, participant characteristics, supplement formulations, and baseline nutritional status. The necessity of standardized research methods is highlighted by these discrepancies. In general, chromium and biotin exhibit promise as supplemental treatments for the treatment of insulin resistance and type 2 diabetes, especially in populations with nutritional deficiencies or metabolic disorders. However, more extensive, carefully planned randomized controlled trials are needed to ascertain the best dosage, long-term safety, and clinical effectiveness.\n\nID: 42511870\nTitle: Rosmarinic Acid Ameliorates Obesity-Associated Metabolic Disturbances and Hepatic Steatosis in Mice with High-Fat Diet-Induced Obesity.\nAbstract: Obesity and obesity-associated hepatic steatosis represent major metabolic health challenges, yet effective pharmacological interventions remain limited. Rosmarinic acid (RA), a natural polyphenol, has been reported to exert anti-obesity effects; however, its specific roles in restoring hepatic lipid homeostasis and modulating glucose metabolism under diet-induced obesity remain unclear. In this study, we investigated the metabolic effects and underlying mechanisms of RA in mice with high-fat diet (HFD)-induced obesity. RA significantly reduced body weight gain and adipose tissue mass without altering total energy intake, accompanied by increased nocturnal energy expenditure and fecal lipid excretion. RA restored hepatic lipid homeostasis by improving circulating lipid profiles and markedly attenuating hepatic steatosis, fibrosis, and hepatocellular injury. These effects were associated with increased fecal lipid excretion, suppression of hepatic lipogenesis, and enhancement of fatty acid oxidation-related markers. Furthermore, RA reduced fasting blood glucose levels and modulated the expression of hepatic glucose metabolism-related genes. Pancreatic immunohistochemistry showed morphological changes in insulin-positive and glucagon-positive cells following RA supplementation. Collectively, these findings indicate that RA ameliorates obesity-associated metabolic disturbances and hepatic steatosis through coordinated regulation of lipid metabolism and hepatic glucose metabolism-related pathways, highlighting its potential relevance for obesity-associated fatty liver conditions.\n\nID: 42511292\nTitle: Combined Supplementation of Rumen-Protected Algae Powder and Rumen-Protected Choline Increases Docosahexaenoic Acid Content in Goat Milk.\nAbstract: Docosahexaenoic acid (DHA) is an essential omega-3 polyunsaturated fatty acid with important health benefits. However, DHA enrichment in ruminant milk is limited by inefficient post-absorptive transport. This study evaluated whether combined supplementation of rumen-protected algae powder (RPA) and rumen-protected choline (RPC) enhances DHA enrichment in goat milk. Nine lactating dairy goats were assigned to three groups (n = 3/group) for 28 days: RPA alone, RPA + low-dose RPC (5 g/d), and RPA + high-dose RPC (10 g/d). Milk DHA content, bioconversion efficiency, serum biochemical parameters, and lipid profiles were analyzed. Compared with RPA alone, low- and high-dose RPC increased milk DHA content to 27.98 and 33.50 mg/100 mL, respectively, representing increases of 23.0% and 47.3%, and enhanced DHA bioconversion efficiency to 20.66% and 24.29% compared with 16.86% in the RPA group. RPC supplementation increased serum VLDL and triglyceride concentrations, and lipidomics revealed increased DHA-containing triglycerides (TG-DHA). These findings suggest that RPC may enhance DHA enrichment in goat milk by promoting VLDL-mediated DHA transport. Further studies with larger animal populations are required to confirm these effects. These findings contribute to a better understanding of nutritional regulation of DHA transfer and provide insights into strategies for developing DHA-enriched dairy products.\n\nID: 42504853\nTitle: Time-Restricted Feeding With High-Fat Diet Slows Weight Gain and Reduces Renal Calcium Oxalate Crystal Formation Without Reducing Energy Intake.\nAbstract: Renal calcium oxalate stones are closely linked to lipid metabolism disorders. A long-term high-fat diet (HFD) can lead to obesity and other metabolic disorders, which significantly contribute to stone formation. Recent studies indicate that time-restricted feeding (TRF) plays a crucial role in improving metabolic homeostasis and preventing metabolic diseases. However, its impact on kidney stone formation has yet to be investigated. We examined differences in calcium oxalate crystal formation in mouse kidneys using glyoxylic acid (Gly) modeling in HFD mouse models subjected to either ad\u00a0libitum (Ad) feeding or TRF. TRF mitigated weight gain, improved blood lipid metabolism disorders, and reduced lipid deposition in the liver and kidneys, alleviating pathological damage. Compared with the Ad group, the TRF group exhibited lower urinary concentrations of oxalate and calcium ions, which corresponded with reduced expression of OPN and CD44, leading to decreased oxalate crystal formation. Gly intervention in the Ad group increased the expression of TNF-\u03b1 and IL-6 in the kidneys, leading to an imbalance between oxidative stress and antioxidant responses. In contrast, TRF showed significant improvement, potentially linked to activation of the PI3K-AKT pathway. Nighttime TRF, which more closely aligns with the natural work and rest rhythms of mice, produced more pronounced effects than daytime TRF. NR1D1 expression in the kidneys was closely associated with stone formation. TRF can improve lipid metabolism and inhibit the formation of renal calcium oxalate stones, and dietary preventive strategies that align with biological rhythms demonstrate particularly significant effects.\n\nID: 42504494\nTitle: Intermittent Fasting Amplifies Gut-Endocrine Axis Responses to Senna alexandrina Supplementation in Obese Rats.\nAbstract: Obesity induced by high\u2011fat, high\u2011sucrose diets (HFSD) remains a major global health challenge, disrupting lipid metabolism, glucose homeostasis, and gut microbial balance. These disturbances underscore the need for safe interventions capable of restoring metabolic regulation. Senna alexandrina (SA), traditionally used for weight reduction, has recently been shown to modulate the gut microbiota beyond its laxative effects. To enhance efficacy while minimizing adverse outcomes, this study investigated the effects of a low and safe dose of SA combined with intermittent fasting (IF), a strategy that reshapes nutrient availability and microbial dynamics. HFSD\u2011induced obese rats were treated for four weeks with SA leaf powder (300\u00a0mg/kg/day), IF, or both. Bioactive constituents of SA were characterized using LC\u2011HRMS, alongside systematic evaluation of physiological and metabolic parameters-including adiposity, morphometry, lipid profiles, insulin sensitivity markers, and gut-endocrine axis indicators. SA supplementation showed improvements across all parameters, surpassing those achieved with IF alone. Importantly, the combined intervention (SA+IF) yielded complementary benefits, notably enhancing GLUT4 expression, short\u2011chain fatty acid (SCFA) production, peptide YY (PYY) secretion, and reducing the Firmicutes/Bacteroidetes ratio. These findings highlight the complementary roles of SA and IF in metabolic regulation, providing experimental evidence for a potential dietary approach to mitigate obesity\u2011related dysfunction.\n\nID: 42504493\nTitle: Genetic Determinants of Interindividual Differences in Provitamin A Carotenoid Concentrations in Human Adipose Tissue.\nAbstract: Adipose tissue is a major storage site for provitamin A carotenoids (proVA CAR)-mainly \u03b2-carotene (BCAR), \u03b1-carotene (ACAR), and \u03b2-cryptoxanthin (BCRY). However, the determinants of their concentrations in this tissue remain poorly understood. This study aimed to identify genetic variants associated with adipose tissue proVA CAR concentrations. Periumbilical adipose tissue samples were collected on six occasions in 43 healthy adult males and proVA CAR concentrations were quantified by HPLC. Participants were genotyped for 2,398 SNPs in 44 candidate genes involved in CAR and lipid metabolism, and genetic associations were assessed using partial least squares (PLS) regression. Adipose tissue proVA CAR concentrations ranked as BCAR > ACAR > BCRY, with CV ranging from 54 to 66%. PLS regression models integrating fasting plasma proVA CAR concentrations and SNPs explained 69, 59, and 67% of the variability in BCAR, ACAR, and BCRY concentrations, respectively. In a multivariate PLS regression model, the main determinants of proVA CAR concentrations were fasting plasma BCAR and ACAR concentrations and four SNPs-rs4694627 (CXCL8), rs7558381 (IRS1), rs709157 and rs1152004 (PPARG). Interindividual variability in adipose tissue proVA CAR concentrations is partly explained by genetic variation in genes involved in CAR and lipid metabolism.

The aim of our study is to assess the features of metabolic phenotypes and proinflammatory status in young normal weight and overweight adults without significant somatic pathology in 2 groups: up to 35 years and \u226535 years. A cross-sectional study included 159 individuals aged 18 to 45 years with normal and overweight body mass. In addition to standard clinical and laboratory examinations, indices reflecting metabolic disorders and pro-inflammatory status were calculated for all patients. A glucose tolerance test was performed on 61 patients, and the area under the curve (AUC) of plasma glucose levels was assessed. In the subgroup of patients aged 35 years and older, abdominal obesity was twice as common compared to patients younger than 35 years (p<0,001) at comparable body mass index. Patients in the older age group were characterized by higher fasting blood glucose levels (p=0,042), glucose levels 1 hour (p=0,011) and 2 hours (p=0,020) after a standard carbohydrate load, as well as a higher prevalence of dyslipidemia (p=0,001), while no significant differences in pro-inflammatory status were identified. Using a decision tree, the characteristics of metabolic phenotypes in the two age subgroups were determined, taking into account the presence of abdominal obesity and plasma glucose AUC characteristics. Thus, in patients aged 35 years and older, subclinical disorders of carbohydrate and lipid metabolism, as well as abdominal obesity, play a significant role in the development of a metabolically \u00abunhealthy\u00bb phenotype. This phenotype is associated with an increased risk of cardiovascular events and indicates early subclinical aging. \u041e\u0441\u043e\u0431\u0435\u043d\u043d\u043e\u0441\u0442\u0438

Lipid Handling.\nAbstract: Elevated saturated fatty acids, such as palmitic acid (PA), induce lipotoxicity in peripheral nerve cells, a pathological feature of metabolic disorders such as type 2 diabetes and obesity that are frequently associated with neuropathic pain (NP). PA overload elicits a maladaptive stress response characterized by endoplasmic reticulum (ER) stress, disrupted intracellular calcium homeostasis, and impaired autophagic flux, ultimately promoting cell death. Although omega-3 polyunsaturated fatty acids such as docosahexaenoic acid (DHA) protect against PA-induced lipotoxicity (PA-LTx), the mechanisms linking lipid handling, ER stress, and autophagy in Schwann cells remain poorly defined. Here, we investigated how PA and DHA regulate autophagic flux, ER stress signaling, and fatty acid-binding protein 5 (FABP5)-dependent lipid trafficking in immortalized Schwann cells (ISCs). PA exposure (300 \u00b5M PA:150 \u00b5M BSA, 24-48\u00a0h) significantly reduced cell viability, impaired autophagic flux as indicated by LC3-II and p62 accumulation, disrupted autophagosome-autolysosome balance, and increased susceptibility to autophagic inhibition by chloroquine. DHA co-treatment (50 \u00b5M) preserved cell viability, restored autophagic flux, and normalized autophagosome-autolysosome fusion. Mechanistically, PA induced ER stress marked by increased CHOP, ATF4, and Xbp1 expression, along with progressive ER calcium depletion, whereas DHA suppressed these responses and stabilized calcium homeostasis. Building on prior evidence that FABP5 protects neuron-like cells from PA-LTx, we identified a regulatory role for FABP5 in Schwann cells. PA robustly induced FABP5 expression, which was normalized by DHA and modulated by pharmacological manipulation of autophagy. FABP5 silencing exacerbated PA-induced ER stress, triggered a dysfunctional compensatory autophagy response, and impaired DHA-induced lipid droplet formation. Collectively, these findings demonstrate that functional autophagy and FABP5-dependent lipid buffering are critical adaptive responses to lipotoxic stress in Schwann cells, highlighting these pathways as potential therapeutic targets for NP-associated metabolic neuropathies.\n\nID: 42500235\nTitle: Glycemic and lipid responses to selenium-enriched vs. zeaxanthin-enriched eggs in patients with type 2 diabetes: a 12-week randomized controlled trial.\nAbstract: The present study investigated the effect of selenium-enriched eggs (SE egg) vs. zeaxanthin-enriched eggs (ZE egg) on glycemic and lipid metabolism in patients with diabetes. Fifty-eight patients with type 2 diabetes were recruited and randomly divided into group SE egg (27 subjects) and ZE egg (31 subjects). The two groups of participants consumed either SE egg or ZE egg twice a day for a total of 12\u202fweeks of intervention. Fasting blood samples were collected before and after the intervention to detect changes in blood glucose and lipid levels. After the intervention, the fasting blood glucose, homeostatic model assessment of insulin resistance, and triglyceride-glucose index of both SE and ZE groups of subjects significantly decreased (p\u202f<\u202f0.05). Among subjects with a baseline glycosylated hemoglobin A1c (HbA1c)\u202f<\u202f8.9%, eggs from both groups showed an enhanced improvement in glucose and lipid metabolism. The ZE egg group showed a significant decrease in triglycerides (p\u202f=\u202f0.0007) and an increase in homeostatic model assessment of \u03b2-cell function (p\u202f=\u202f0.06). There was no significant difference in HbA1c between the two groups after the intervention. This study demonstrates that SE egg and ZE eggs have comparable effects on improving glucose metabolism profiles in diabetic patients, with an improved efficacy observed in subjects with lower baseline HbA1c levels. Furthermore, ZE eggs suggest potential benefits in lowering TG levels. https://www.chictr.org.cn/index.html, Identifer, ChiCTR2300077522.\n\nID: 42497820\nTitle: Associations between maternal lipid metabolism in early pregnancy and postpartum symptoms of depression and anxiety: results from a longitudinal cohort of 266 women.\nAbstract: The COVID-19 pandemic has exacerbated psychological vulnerability in perinatal women. Emerging evidence suggests a link between systemic inflammation, lipid metabolism, and mental health. This study aims to evaluate whether first-trimester lipid profiles can predict postpartum depression (PPD) and anxiety in the post-pandemic context. A prospective cohort study of 266 pregnant women was conducted. Fasting lipids (Triglycerides, HDL, LDL) were measured at the 12th week of gestation. Mental health was assessed at 3 months postpartum using the Edinburgh Postnatal Depression Scale (EPDS) and Beck Anxiety Inventory (BAI). 22.6% of women exhibited PPD symptoms (EPDS >12). High first-trimester triglycerides (TG) and an elevated TG/HDL ratio (\u22651.9) were significantly associated with higher EPDS scores (p\u202f<\u202f0.001). Multivariable regression confirmed the TG/HDL ratio as an independent predictor of PPD (Adjusted OR 1.65; 95% CI 1.22-2.10). Early pregnancy lipid profiles show significant prospective associations with postpartum psychological distress, suggesting their potential role as early screening candidates that require further validation.\n\nID: 42496959\nTitle: Metabolic engineering of cereal lipids: from omega-3 fatty acids to wax esters and pheromones.\nAbstract: Cereals are emerging as attractive platforms for the sustainable production of high-value lipids through metabolic engineering. Although plant lipids play essential biological roles and have considerable economic value, their conventional production from natural sources is often limited by sustainability, scalability and cost. Recent advances in synthetic biology enable the reprogramming of seed lipid metabolism for the tailored synthesis of valuable lipid compounds. In this review, we first summarize the core pathways of fatty acid biosynthesis and triacylglycerol assembly in seeds, together with the genetic transformation and genome editing toolkits available for major cereals. We then highlight recent progress in the heterologous production of specialized lipids, including eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), wax esters, and insect sex pheromones, in engineered plant systems. Finally, we discuss the potential of cereals as scalable and sustainable platforms for the production of high-value lipids. Together, these advances position engineered cereals as promising plant-based factories for applications in agriculture, nutrition, and the emerging bio-based economy.\n\nID: 42496147\nTitle: Longer-Term Efficacy and Safety of Zodasiran in Patients with Mixed Hyperlipidaemia.\nAbstract: Mixed hyperlipidaemia, characterized by elevated cholesterol and triglyceride levels, is associated with increased risk of atherosclerotic cardiovascular disease (ASCVD). Angiopoietin-like protein 3 (ANGPTL3) regulates lipid metabolism through inhibition of lipoprotein and endothelial lipases. Loss-of-function variants in ANGPTL3 are associated with lower plasma triglycerides, cholesterol, and reduced ASCVD risk. Zodasiran, a hepatocyte-targeted small interfering RNA (siRNA) against ANGPTL3, demonstrated significant lipid lowering in the Phase 2b ARCHES-2 trial. To evaluate the long-term safety and efficacy of zodasiran in adults with mixed hyperlipidaemia participating in the open-label extension (OLE) of ARCHES-2 (NCT04832971). Adults with mixed hyperlipidaemia (fasting triglycerides 1.7-5.6\u2005mmol/L and LDL-C\u2009\u2265\u20091.8\u2005mmol/L or non-HDL-C\u2009\u2265\u20092.59\u2005mmol/L) who completed 9 months of randomised treatment with placebo or zodasiran (50-, 100-, or 200-mg subcutaneously Q3\u2005M) were eligible for the OLE. The primary endpoint in the randomised doubleblind study was percent change in median triglycerides from baseline to Month 6. Here, lipid parameters were assessed through 21 months of the OLE; with total follow-up of 24 months. Of 191 participants completing randomised treatment, 156 (82%) enrolled in the OLE. Over 24 months, zodasiran was generally well tolerated; five participants (3.2%) discontinued due to adverse events; one (0.6%) death, not considered treatment-related, occurred. Injection site reactions were mild. By Month 21, median triglycerides were reduced by -55% (95% CI, 64, 43); remnant cholesterol by -57% (SD: 32); LDL-C by -5% (SD: 40); and ApoB by -13% (SD: 21). Zodasiran produced sustained reductions in triglycerides and atherogenic lipoproteins over 30 months and was well tolerated, supporting its potential as a long-term therapeutic option for mixed hyperlipidaemia. In this study, called the ARCHES-2 OLE study, we looked at the long-term safety and efficacy of zodasiran, an investigational medicine, in the treatment of mixed hyperlipidaemia.Mixed hyperlipidaemia is a disorder in which both triglycerides as well as LDL-cholesterol or non-HDL-cholesterol (\u201cbad\u201d cholesterol) are elevated.\u2022 Patients with mixed hyperlipidaemia have an increased risk for cardiovascular disease so it is important to diagnose and treat it as early as possible.\u2022 We had previously found that treatment with zodasiran could reduce triglycerides in these patients.In our current study, 156 adult patients with mixed hyperlipidaemia from that initial 9-month study were injected with zodasiran for an additional 2 years\u2022 The injection was given once every 3 months.\u2022 The treatment was well tolerated and reduced triglycerides as well as LDL-cholesterol and other disease-causing lipids.\u2022 These results are promising and we are now planning larger clinical studies to confirm these effects.\n\nID: 42494692\nTitle: Fermented cassava peel with Pleurotus ostreatus as a functional feed: Effects on growth performance, gut health, microbiota, and meat quality in broiler chickens.\nAbstract: The utilization of agro-industrial by-products as alternative feed ingredients has gained increasing attention in poultry production. Cassava peel is abundant but limited by high fiber and anti-nutritional factors. Fermentation using Pleurotus ostreatus can improve its nutritional quality and generate bioactive compounds. This study aimed to evaluate the effects of fermented cassava peel (FCP) on growth performance, carcass traits, immune response, intestinal morphology, microbial population, blood biochemical parameters, and fatty acid profile in broiler chickens. A total of broilers were randomly assigned to five dietary treatments: FCP0, FCP5, FCP10, FCP15, and FCP20, representing 0%, 5%, 10%, 15%, and 20% inclusion levels of FCP in the diet. The experiment was conducted over 35 days, including starter and finisher phases. Parameters measured included average daily weight gain (ADWG), average daily feed intake (ADFI), feed conversion ratio (FCR), live body weight (LBW), carcass characteristics, immune organ weights, intestinal villus height (VH), crypt depth (CD), VH/CD ratio, gut microbiota, blood lipid profile, and thigh meat fatty acid composition. Dietary inclusion of FCP significantly improved ADWG and LBW, particularly at the 20% level, without affecting ADFI and FCR. Carcass weight and percentage increased significantly (p < 0.05), while abdominal fat and physiological organs remained unaffected. Thymus weight and percentage were significantly increased, indicating enhanced immune response. Intestinal morphology showed increased VH and VH/CD ratio and decreased CD, reflecting improved absorptive capacity. Microbial analysis revealed reduced Escherichia coli and increased lactic acid bacteria populations. Blood analysis indicated reduced total cholesterol, triglycerides, and low-density lipoprotein, with increased high-density lipoprotein (p < 0.05). Although meat cholesterol was unchanged, FCP improved fatty acid composition by increasing omega-3, omega-6, omega-9, docosahexaenoic acid and eicosapentaenoic acid levels. FCP is an effective functional feed ingredient that enhances growth performance, gut health, immune status, and lipid metabolism in broiler chickens. Inclusion up to 20% can be recommended as a sustainable and economically viable strategy to improve poultry productivity and meat quality.\n\nID: 42494617\nTitle: High-Protein Diet Combined With Lactobacillus acidophilus Improves Weight Loss, Lipid Metabolism, and Gut Microbiota in Obese Rats.\nAbstract: This study evaluated whether Lactobacillus acidophilus supplementation provides additional benefits to a whey protein-based high-protein diet (HPD) in diet-induced obese rats. After obesity induction, 48 male Wistar rats were assigned to four 12-week interventions (n\u2009=\u200912/group): ND1 (140\u2009g/kg whey protein isolate), ND2 (ND1\u2009+\u2009L. acidophilus), HPD1 (500\u2009g/kg whey protein isolate) and HPD2 (HPD1\u2009+\u2009L. acidophilus). Supplemented groups received 5\u2009\u00d7\u2009108\u2009CFU/rat/day by oral gavage. Food intake, body-weight change, regional fat mass, serum biochemical markers and gut microbiota composition were evaluated. HPD-fed rats showed lower food intake, sustained body-weight loss and reduced visceral and epididymal fat masses compared with rats receiving normal-protein diets. Body-weight trajectories differed between dietary regimens (p\u2009=\u20090.013), whereas weight loss did not differ significantly between HPD1 and HPD2 (p\u2009=\u20090.06). Fasting glycemia remained unchanged. At month 3, ND1 showed the highest triglyceride and total cholesterol concentrations, while ND2, HPD1 and HPD2 displayed lower terminal values. High-protein feeding was associated with higher terminal urea and uric acid concentrations, whereas creatinine did not progressively increase. In the microbiota subset, HPD2 was characterized by higher relative abundances of Lactobacillus and Turicibacter. The whey protein-based HPD was the principal factor associated with body-weight reduction, lower adiposity and favorable lipid responses in obese rats. Under high-protein conditions, L. acidophilus did not confer an additional benefit for body weight or serum lipids, although its effect on gut microbiota composition warrants further functional investigation.\n\nID: 42488218\nTitle: Bletilla striata oligosaccharides alleviate high-fat diet-induced metabolic associated fatty liver in mice through modulation of gut microbiota and host metabolism.\nAbstract: Gut-liver axis dysfunction drives metabolic associated fatty liver disease (MAFLD), but effective therapeutic strategies remain limited. Bletilla striata oligosaccharides (BSO) have immunomodulatory potential, yet their role in MAFLD via the gut-liver axis is unclear. This study aimed to investigate whether and how BSO ameliorates MAFLD by modulating gut microbiota, intestinal barrier function, and hepatic inflammation. MAFLD was induced in mice by 8-week high-fat diet followed by 12-week BSO (150, 300, 600 mg/kg) or metformin treatment via oral gavage. Compared with the MAFLD model, high-dose BSO reduced body weight gain, lowered fasting glucose, and decreased hepatic triglycerides. BSO also attenuated liver injury, hepatic steatosis, inflammation. Mechanistically, BSO restored gut barrier integrity, upregulated colonic tight junction proteins, activated colonic LXR\u03b1/ABCA1 signaling, while suppressing the hepatic TLR4/NF-\u03baB pathway. BSO remodeled gut microbiota, enriching beneficial Lachnospiraceae and Oscillospiraceae, and modulated hepatic metabolites, as shown by decreased confertifoline along with increased D-myo-inositol-4-phosphate. Additionally, BSO activated the intestinal FXR/FGF15 axis and ameliorated bile acid metabolism disorders, evidenced by reduced tauro-\u03c9-muricholic acid and cholic acid. This study provides systematic evidence that BSO alleviates MAFLD through a multi-target gut-liver axis mechanism involving gut microbiota remodeling, barrier restoration, activation of LXR\u03b1/ABCA1 and FXR/FGF15 signaling, and subsequent suppression of hepatic TLR4/NF-\u03baB-driven inflammation. Compared to previous approaches, BSO offers a favorable safety profile with combined regulatory effects. These findings support BSO as a promising candidate for MAFLD treatment, with potential applications as a dietary supplement or prebiotic agent.\n\nID: 42483677\nTitle: Effects of high-intensity interval training and moderate-intensity continuous training on type 2 diabetes mellitus: a meta-analysis and systematic review.\nAbstract: This meta-analysis compared the effects of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on type 2 diabetes (T2DM). A systematic search of the PubMed, Web of Science, Cochrane Library and Embase databases (from the inception of each database to 16 November 2025) identified a total of 21 randomized controlled trials involving 792 participants. A pooled analysis was conducted using standardized mean differences (SMD) and 95% confidence intervals. The results showed no significant differences between HIIT and MICT in terms of glycated hemoglobin (HbA1c), fasting blood glucose, HOMA-IR, body mass index (BMI), total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL) or blood pressure. However, HIIT demonstrated a significant advantage in improving high-density lipoprotein cholesterol (HDL) (SMD 0.44, p = 0.023). Subgroup analyses indicated that moderate training duration (20-30 minutes), lower weekly training frequency (\u22643 sessions) and shorter intervention duration (\u22648 weeks) optimized the benefits of HIIT on HDL. These findings suggest that HIIT is an effective alternative to MICT for patients with type 2 diabetes, particularly those with time constraints and whose primary metabolic abnormality is characterized by low HDL levels. Personalized exercise prescriptions should consider training duration and weekly training frequency as key modifiers. https://www.crd.york.ac.uk/PROSPERO/, identifier CRD420261343976.\n\nID: 42482103\nTitle: Caloric restriction enhances radiosensitivity of colorectal tumors through the cGAS-STING pathway activation.\nAbstract: Although radiotherapy is an important clinical option for colorectal cancer, its efficacy is limited by intrinsic tumor radioresistance and radiation-induced toxicity in surrounding normal tissues. This study investigated the radiosensitizing effects of either 7-day 30% caloric restriction (CR) or 24-hour fasting in a murine model bearing CT-26 colorectal tumor and explored the underlying mechanisms. CR and fasting pretreatment enhanced irradiation-induced tumor apoptosis, mitochondrial dysfunction, and cytosolic DNA stress, leading to activation of the cyclic GMP-AMP synthase/stimulator of interferon gene (cGAS-STING) pathway, increased infiltration of tumor killing-associated CD8\u2009+\u2009cytotoxic T lymphocytes, and modulation of macrophage polarization toward an antitumor phenotype. In addition, CR and fasting further suppressed the expression of glycolysis and lipid metabolism related proteins in the tumor microenvironment upon radiation exposure. By contrast, CR and fasting protected normal intestinal tissue from irradiation-induced damage. These findings were validated in vitro using CT-26 and normal small intestinal epithelial cells (IEC-6) cultured under medium with or without glucose. The critical role of the cGAS-STING pathway in enhancing radiosensitivity was confirmed through STING siRNA-mediated knockdown, combined with pharmacological intervention using the STING agonist MSA-2 and inhibitor H-151. In conclusion, our findings indicate that CR and fasting may increase the radiosensitivity of colorectal tumors, while reducing radiation injury to normal intestinal tissue.\n\nID: 42478706\nTitle: Antidiabetic and Anti-Obesity Effects of Betalains: A Systematic Review of Preclinical Evidence.\nAbstract: Metabolic disorders like diabetes and obesity represent major global health challenges, largely driven by unhealthy dietary patterns and sedentary lifestyles. Growing interest in natural bioactives as complementary strategies is increasing. Betalains, primarily derived from Beta vulgaris, exhibit notable antidiabetic and anti-obesity properties, highlighting their therapeutic potential. This systematic review evaluates the antidiabetic and anti-obesity effects of betalains based on in vitro and in vivo evidence. Literature published between 2015 and 2025 was retrieved from PubMed, ScienceDirect, Scopus, Web of Science, and Google Scholar. Eligible studies assessed betalains effects on glucose and lipid metabolism, while reviews and irrelevant reports were excluded. Out of 508 identified studies, only 12 met the inclusion criteria. The systematic review was registered in PROSPERO under ID 1357942. Risk of bias was assessed using the OHAT tool for in vitro studies and the SYRCLE tool for animal studies. Betalains demonstrated significant metabolic benefits by reducing triglyceride accumulation, fasting blood glucose, insulin resistance, and NF-\u03baB activation, while increasing insulin, adiponectin, and HDL-C levels. They also downregulated total cholesterol, LDL-C, and lipogenic markers (PPAR\u03b3, SREBP-1c). Overall, betalains show potential as natural agents against diabetes and obesity; however, well-designed clinical trials with standardized dosing are needed to confirm long-term efficacy.\n\nID: 42473553\nTitle: Targeting Lipid Metabolic Reprogramming to Overcome Immunotherapy Resistance: Systemic Nutritional Modulation and Precision Nanomedicine.\nAbstract: Despite the clinical success of immune checkpoint inhibitors (ICIs), resistance driven by a metabolically hostile tumor microenvironment (TME), particularly lipid metabolic reprogramming, remains a formidable challenge. Tumors actively exploit lipid mediators, notably prostaglandin E2 (PGE2), to suppress CD8+ T cells and promote immunosuppressive macrophage polarization. Although targeted nanotherapeutics aim to locally reverse these defects, their in vivo efficacy is frequently abrogated by the host's nutritional baseline. Specifically, high dietary intake of Omega-6 polyunsaturated fatty acids fuels systemic PGE2 biosynthesis, creating a metabolic \"sink\" that localized nanotherapies struggle to neutralize. To address this limitation, this review proposes a dual-compartment therapeutic framework combining systemic dietary modulation with precision nanotherapy. As a distinctive contribution, we bridge these biological mechanisms with pharmaceutical design by integrating critical translational barriers, advanced formulation strategies, and emerging technologies for lipid reprogramming. Building upon this, we critically evaluate the most promising formulations, including stimuli-responsive and lipid-targeted nanocarriers, to elucidate their synergistic potential with nutritional interventions. Ultimately, pairing systemic Omega-3 dietary preconditioning with localized nanotherapeutics provides a biologically rational strategy to dismantle lipid-driven immune evasion. Maximizing patient outcomes and advancing future clinical prospects will depend on the rigorous translation of these combinatorial regimens to effectively overcome ICI resistance.\n\nID: 42473028\nTitle: Electroacupuncture Treatment on Sarcopenia in Patients Undergoing Maintenance Haemodialysis: An Effective Therapy.\nAbstract: Electroacupuncture (EA) treatment has been utilized for recovery from neuromuscular-related diseases and may play a significant role in the treatment of sarcopenia. This interventional, randomized controlled clinical study aims to explore the efficacy of EA treatment in maintenance haemodialysis (MHD) patients with sarcopenia. Thirty-six participants with sarcopenia undergoing MHD were randomly divided into the control group and the EA group. The participants in the EA group received a total of 24 treatments, each lasting 30\u2009min, and were administered three times per week. Participants in the control group were instructed to continue their current lifestyle and treatment plans. The assessments were conducted at baseline and after 8\u2009weeks. Statistical analysis was performed using two-way analysis of covariance (ANCOVA) adjusted according to gender and baseline values. Repeated measures analysis of variance (ANOVA) was used to assess EA effects, reporting main effects and the time\u2009\u00d7\u2009group interaction with partial eta squared (\u03b72p) effect sizes. The primary outcome was 6-m gait speed; the secondary outcomes were skeletal muscle mass index (SMI) and handgrip strength. Fasting blood samples were collected, and serum metabolomics using the liquid chromatography-mass spectrometry method was employed to reveal metabolic changes. One participant from the EA group dropped out, and 35 participants were included in the analysis, aged (59.06\u2009\u00b1\u200911.69) years, including 22 men and 13 women. After intervention, the 6-m gait speed of the EA group increased (\u0394\u2009=\u20090.10\u2009\u00b1\u20090.08; p\u2009<\u20090.001), whereas that of the control group decreased (\u0394\u2009=\u2009-0.06\u2009\u00b1\u20090.09; p\u2009=\u20090.018). The handgrip strength of the EA group increased (\u0394\u2009=\u20090.68\u2009\u00b1\u20090.98; p\u2009=\u20090.011), whereas that of the control group decreased (\u0394\u2009=\u2009-0.76\u2009\u00b1\u20091.19; p\u2009=\u20090.015). The SMI in the EA group increased (\u0394\u2009=\u20090.19\u2009\u00b1\u20090.22; p\u2009=\u20090.003), although there was no significant difference in the control group. No serious adverse events were observed during the EA treatment. The results of serum metabolomics indicated that a total of 127 differentially expressed metabolites were identified (p\u2009<\u20090.05, VIP >\u20091), including 35 up-regulated metabolites and 92 down-regulated metabolites. KEGG pathway enrichment analysis showed that glycerophospholipid metabolism, linoleic acid metabolism and other pathways related to lipid metabolism were significantly changed. EA treatment was an effective therapy for sarcopenia in patients undergoing MHD. Its therapeutic effect may be related to the positive regulation of systemic metabolism (including amino acid and lipid profiles).\n\nID: 42471109\nTitle: Modulation of the gut microbiota by Lacticaseibacillus paracasei reduces adipogenesis and metabolic dysregulation in high-fat diet-induced obese mice.\nAbstract: The rising interest in microbiota-based therapies has positioned probiotics as promising candidates for managing obesity. This study evaluated the effects of Lacticaseibacillus paracasei in a murine model of high-fat diet (HFD)-induced obesity. Oral administration of L. paracasei significantly reduced body weight gain and adiposity without altering food intake, indicating improved energy efficiency. Probiotic supplementation enhanced insulin sensitivity and glucose tolerance, as shown by lower fasting glucose, insulin levels, and HOMA-IR. At the molecular level, L. paracasei downregulated adipogenic genes (Srebf1, Pparg, Cebpa, Fabp4) and upregulated Ucp-1, suggesting increased browning of white adipose tissue. Inflammatory markers (Tnf-\u03b1, Il-6, Mcp-1) and JNK pathway activation were decreased, while insulin signaling and lipid metabolism improved via increased Glut4 and Ppar\u03b1, and modulation of adipokines. In the liver, the probiotic attenuated steatosis, reduced oxidative stress, and modulated genes related to lipid metabolism. Gut barrier integrity was improved, as indicated by higher expression of tight junction proteins, lower LPS levels, and reduced Tlr4 expression. L. paracasei also reshaped the gut microbiota, decreasing the Bacillota/Bacteroidota ratio and increasing beneficial taxa such as Akkermansia muciniphila and Lactobacillus, while reducing Clostridium spp. Additionally, it normalized obesity-associated miRNAs involved in adipogenesis and inflammation. Finally, the probiotic improved endothelial function and reduced vascular oxidative stress. These results support L. paracasei as a promising probiotic for obesity management, acting through metabolic, inflammatory, and microbiota-mediated mechanisms.\n\nID: 42464312\nTitle: Synergistic effect of AIP and cystatin C: a study on cardiovascular risk prediction in populations with different glycemic statuses.\nAbstract: Cardiovascular disease (CVD) poses a major global health burden. The Atherogenic Index of Plasma (AIP) and Cystatin C are novel biomarkers reflecting lipid metabolism disorders and renal/micro-inflammatory status, respectively. Their combined indicator (AIP-Cys, the product of AIP\u2009\u00d7\u2009Cystatin C) may provide improved predictive value beyond either marker alone. This study aimed to investigate the predictive role of AIP-Cys for the risk of incident CVD across different glycemic statuses: normal glucose regulation (NGR), pre-diabetes (preDM), and diabetes mellitus (DM). This study was based on the prospective China Health and Retirement Longitudinal Study (CHARLS) cohort. A total of 6,035 participants aged\u2009\u2265\u200945 years without a history of CVD at baseline (2011) were included. The primary exposure was baseline AIP-Cys (the product of AIP\u2009\u00d7\u2009Cystatin C), and the outcome was the first self-reported incident heart disease or stroke event during follow-up (until 2020). Glycemic status was defined based on fasting plasma glucose and glycated hemoglobin levels. Multivariable Cox proportional hazards models were used to estimate hazard ratios (HRs). Restricted cubic splines and piecewise linear models were applied to analyze nonlinear relationships. Mediation and sensitivity analyses were conducted to verify the robustness of the results. During a median follow-up of 9.0 years, 651 incident CVD cases occurred. In the fully adjusted model, AIP-Cys was independently associated with CVD risk in the overall (HR per unit increase: 1.34; 95% CI: 1.06-1.69), NGR (HR: 1.60; 95% CI: 1.13-2.26), and preDM (HR: 1.32; 95% CI: 1.02-1.70) populations, but not in the DM population. RCS analysis revealed a significant nonlinear relationship in the NGR and preDM groups (P for nonlinearity\u2009<\u20090.05). Piecewise regression identified inflection points (0.47 for NGR; 0.37 for preDM), below which risk increased sharply. Quartile analysis showed the highest risk in Q3 rather than Q4, suggesting a saturation effect. Mediation analysis indicated that systolic blood pressure partially mediated this association (mediating proportion: 14.6% in overall population). The predictive performance of AIP-Cys was modest for short-term risk (1-year AUC: 0.64-0.67) but limited for long-term prediction. The composite indicator AIP-Cys, derived from AIP and Cystatin C, is an independent risk factor for incident CVD in individuals with NGR and preDM. The association exhibits a nonlinear threshold pattern. However, its predictive value is limited in the DM population, and its long-term predictive performance is modest. Additionally, the self-reported nature of cardiovascular outcomes represents a limitation that should be considered when interpreting these findings. By integrating lipid metabolism and renal/inflammatory pathways, this indicator offers a novel biomarker-based approach for early cardiovascular risk identification in the pre-diabetes stage. Future research should further explore its potential for clinical translation and intervention.\n\nID: 42463009\nTitle: Neuronal ketone body utilization couples exercise and time-restricted feeding to cognitive enhancement.\nAbstract: Ketone body metabolism is linked to brain health benefits, including delaying age-related cognitive decline. Exercise, particularly when combined with an overnight fast, stimulates ketone body turnover and improves brain metabolism and cognition. Yet, whether ketone metabolism is obligatory for this response is unknown. Here, we use chronic exercise via voluntary wheel running plus time-restricted feeding (VWR + TRF) to explore whether ketones mediate exercise-induced brain health benefits in middle-aged mice. To distinguish the roles of neuronal ketone metabolism vs. hepatic ketone production, we studied middle-age female neuronal-specific SCOT knockout mice and hepatocyte-specific HMGCS2 knockout mice, respectively. VWR + TRF was compared to sedentary ad-libitum fed mice to assess the impact on whole-body metabolism, cognition, and hippocampal molecular adaptations. VWR + TRF upregulated systemic lipid oxidation in all mice during the fasting period. In female SCOT-Neuron-KO mice, we show impaired responses to VWR + TRF in indices of short- and long-term memory. Proteomic analysis of isolated hippocampi revealed that SCOT-Neuron-KO mice failed to globally upregulate key facilitators of synaptic function, including leucine-rich repeated transmembrane proteins, neurexins, and neuroligins. In female HMGCS2-Liver-KO mice, impaired responses to VWR + TRF in indices of short-term memory were paired with an upregulation in hippocampal ketogenesis machinery, suggesting potential in vivo evidence of cerebral ketogenesis, a mechanism mitigating an otherwise more pronounced behavioral phenotype. Together, these findings suggest that neuronal ketone body utilization is essential for, while hepatic-derived ketone bodies contribute to, the full cognitive and synaptic adaptations to VWR + TRF, supporting ketone metabolism as a key mechanistic link between metabolic state and brain health in midlife.\n\nID: 42460488\nTitle: Dietary 1,3-diacylglycerols rich in \u03b3-linolenic and stearidonic acids improve metabolic parameters and tissue lipid profiles in high-fat diet-induced obese mice.\nAbstract: Structured lipids (SLs) enriched in \u03b3-linolenic acid (GLA) and stearidonic acid (SDA) were synthesized as 1,3-diacylglycerols (1,3-DAGs) and evaluated in a high-fat diet (HFD)-induced obesity mouse model. Male C57BL/6J mice were fed control or HFD diets, with or without 2% SL supplementation, for 12 weeks. HFD feeding markedly increased the body weight, hepatic steatosis, insulin resistance, dyslipidemia, inflammation, and oxidative stress and altered hepatic gene expression. SL supplementation significantly attenuated weight gain without affecting the energy intake, reduced hepatic steatosis and adiposity, and improved glucose homeostasis. Serum triglycerides, total cholesterol, LDL-cholesterol, and transaminase activities were normalized, while pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6) and oxidative stress markers were reduced. The antioxidant capacity was restored, with normalization of SOD, CAT, GPX, and GR activities. At the transcriptional level, SLs reactivated PPAR-\u03b1 signaling, enhanced CPT-I and ACOX expression, and suppressed lipogenic genes (SREBP-1c, ACC, FAS), thereby promoting fatty acid oxidation and attenuating lipogenesis. Desaturase activities (\u03945D, \u03946D) were modulated, improving n-6/n-3 ratios in liver and adipose tissue, with tissue-specific responses observed in the brain. Dietary GLA- and SDA-enriched 1,3-DAGs reprogrammed lipid metabolism, mitigated HFD-induced metabolic dysfunction, and enhanced PUFA profiles, exerting protective effects against obesity-related dyslipidemia, oxidative stress, and inflammation. These findings highlight their potential as functional lipids for nutritional strategies targeting obesity and metabolic disorders.\n\nID: 42458511\nTitle: Early-pregnancy glucose-lipid signatures and metabolic heterogeneity of gestational diabetes with extension to hypertensive comorbidity in singleton and twin pregnancies: a multicenter cohort study.\nAbstract: Early pregnancy is a critical window for metabolic adaptation, marked by coordinated regulation of glucose and lipid metabolism. Disruption of this balance may contribute to gestational diabetes mellitus (GDM), a condition increasingly recognized as metabolically heterogeneous. Whether early-pregnancy glucose-lipid indices capture this heterogeneity and extend to hypertensive disorders of pregnancy (HDP) remains unclear. This retrospective multicenter cohort included 13,419 pregnancies (11,765 singleton and 1,654 twin pregnancies). Fasting glucose and lipid measurements obtained at 5-16\u00a0weeks of gestation were used to derive eight composite indices, including the triglyceride-glucose (TyG) index, TyG-BMI, METS-IR, SPISE, AIP, CHG, NHHR, and lnRC. Multinomial logistic regression evaluated associations with GDM subtypes (post-load, isolated fasting, and combined GDM), using normoglycemia as the reference. Extension analyses assessed GDM-HDP phenotypes (GDM-only, HDP-only, and combined GDM-HDP) relative to normoglycemic-normotensive pregnancies. Restricted cubic spline models examined dose-response relationships, and receiver operating characteristic analyses assessed discriminative performance. Early-pregnancy glucose-lipid indices showed a clear gradient across GDM subtypes, with progressively stronger associations from post-load GDM to isolated fasting GDM and combined GDM; adjusted odds ratios (ORs) per unit increase in TyG index were 2.54, 6.21, and 8.91, respectively. When analyses were extended to hypertensive outcomes, the strongest association was observed for combined GDM-HDP (adjusted OR, 4.81; 95% confidence interval, 3.35-6.89). Significant interaction with prepregnancy overweight status was observed for TyG-BMI, with more pronounced heterogeneity across HDP-related phenotypes, whereas associations were directionally similar across singleton and twin pregnancies after accounting for center composition. For the highest-risk phenotypes, area under the curve (AUC) values were 0.786 for combined GDM (TyG index and TyG-BMI) and 0.811 for combined GDM-HDP (TyG-BMI). A significant interaction between fasting glucose and high-density lipoprotein cholesterol was detected for both combined GDM (interaction OR 3.61) and combined GDM-HDP (interaction OR 3.79). Early-pregnancy glucose-lipid indices are associated with a graded pattern of metabolic heterogeneity across GDM subtypes, and a similar pattern is observed for hypertensive comorbidity. These findings are consistent with shared metabolic perturbations underlying glycemic and vascular complications during pregnancy and may inform future approaches to early-pregnancy risk assessment.\n\nID: 42453674\nTitle: WWP1 modulates metabolic adaptation in white adipose tissue but does not significantly modify caloric restriction-induced longevity in mice.\nAbstract: Caloric restriction (CR) extends lifespan across diverse species. While the WW domain-containing E3 ubiquitin ligase1 (WWP1) is an essential mediator of dietary restriction-induced longevity in Caenorhabditis elegans, its role in mammalian CR remains unclear. In this study, we investigated the role of WWP1 in CR-mediated longevity and metabolic adaptation using systemic Wwp1 knockout (KO) mice. Male wild-type (WT) and Wwp1 KO mice were subjected to either ad libitum (AL) feeding or long-term CR (70% of AL intake) and monitored throughout their natural lifespan. As a result, Wwp1 deficiency did not markedly modify the CR-associated survival response in mice. Despite comparable food intake, CR-Wwp1 KO mice after middle age exhibited a modest increase in body weight compared with CR WT mice. WWP1 deficiency selectively enhanced CR-induced, Srebp-1c-dependent expression of proteins involved in de novo fatty acid synthesis in epididymal WAT, whereas hepatic lipid metabolism was unaffected. Collectively, our results demonstrated that, unlike in C. elegans, WWP1 is not required for CR-induced longevity in mammals; rather, it acts as a partial suppressor of CR-driven de novo fatty acid metabolism, limits energy storage and lipid retention in WAT.\n\nID: 42451188\nTitle: Associations of Serum 25-Hydroxyvitamin D Concentrations and Lipid Profiles Across Adiposity Status Among Children and Adolescents Aged 9-17 Years: A Cross-Sectional Study in Guangzhou, China.\nAbstract: Background: Childhood dyslipidemia often tracks into adulthood and contributes to early atherosclerotic changes. Although serum 25-Hydroxyvitamin D (25(OH)D) has been implicated in lipid metabolism, findings in children remain inconsistent, and whether these associations differ by overweight/obesity (ow/ob) status is unclear. We therefore aimed to investigate the associations of serum 25(OH)D concentrations and lipid profiles stratified by ow/ob status among children and adolescents aged 9-17 years. Methods: This cross-sectional study included 3067 children and adolescents from Guangzhou, southern China. Anthropometric measurements were obtained by trained staff, and ow/ob status was classified according to WHO criteria. Fasting blood samples were collected to measure serum 25(OH)D and lipid parameters. Multivariable regression analyses were adopted to determine the associations between serum 25(OH)D and lipid profiles. Stratified analysis and interaction tests were further applied according to ow/ob status. Results: Higher 25(OH)D concentrations were most consistently associated with lower TG (\u03b2 = -0.026; 95% CI, -0.040 to -0.011), higher HDL-C (\u03b2 = 0.025; 95% CI, 0.014 to 0.035), and lower TG/HDL-C ratios (\u03b2 = -0.044; 95% CI, -0.061 to -0.027). Positive associations were also observed for TC, LDL-C, and non-HDL-C with serum 25(OH)D, but these were attenuated after further adjustment for HDL-C. No significant association was observed for the TC/HDL-C ratio. In stratified analyses, associations with several lipid parameters were observed mainly among children and adolescents without ow/ob, whereas significant inverse associations among those with ow/ob were largely limited to TG and the TG/HDL-C ratio. Significant interactions between vitamin D and ow/ob status were observed for TC and non-HDL-C, but were attenuated after further adjustment for HDL-C. Conclusions: In this cross-sectional study, serum 25(OH)D was associated with several lipid parameters among children and adolescents, most consistently with TG, HDL-C, and the TG/HDL-C ratios. Stratified analyses showed different vitamin D-lipid association patterns across ow/ob status, with statistically significant interactions observed only for TC and non-HDL-C. The attenuation of several associations after adjustment for HDL-C suggests that HDL-C may be involved in these observed patterns. Future longitudinal studies are needed to examine causality of vitamin D-lipid associations and the potential role of HDL-C in these associations.\n\nID: 42451149\nTitle: MELHAC Improves Glucose and Lipid Metabolism in HFD + Alloxan-Induced Mice.\nAbstract: Background: Glucose and lipid metabolism disorders are characterized by hyperglycemia, dyslipidemia, hepatic oxidative stress, lipid accumulation, and gut microbiota dysbiosis, all of which contribute to progressive metabolic dysfunction and tissue injury. As a plant extract mixture derived from mulberry leaves, lotus leaves, and Eucommia leaves, MELHAC (Mulberry-Eucommia-Lotus Herbal Aqueous Complex) was developed as a medicinal and edible formula with potential multi-component metabolic regulatory activity. In the present study, we systematically evaluated the effects of MELHAC on glucose and lipid metabolic abnormalities in high-fat diet (HFD) plus alloxan-induced mice. Methods: The phytochemical profile of MELHAC was characterized using untargeted LC-MS and network pharmacology. Its metabolic effects were evaluated in HFD plus alloxan-induced mice by measuring fasting blood glucose, serum lipid parameters, glucose tolerance, hepatic oxidative stress markers, histopathological changes, hepatic lipid accumulation, gut microbiota composition, and preliminary safety indices. Results: Chemical characterization revealed that MELHAC contains abundant bioactive constituents dominated by flavonoids, phenolic acids and alkaloids. In vivo experiments demonstrated that MELHAC lowered fasting blood glucose, total cholesterol and triglyceride levels, while ameliorating glucose intolerance and pathological damage in the liver, kidney and pancreas. MELHAC also improved liver-related biochemical abnormalities, increased hepatic superoxide dismutase, decreased malondialdehyde, and reduced hepatic lipid accumulation, indicating protective effects against oxidative stress and steatosis associated with metabolic dysfunction. In addition, MELHAC modulated gut microbial community structure and differential taxa linked to metabolic homeostasis. Short-term high-dose administration did not cause obvious abnormalities in serum biochemical, hematological, or histopathological indices. Conclusions: These findings suggest that MELHAC has potential as a plant-derived functional ingredient for improving glucose and lipid metabolic disorders and may provide an experimental basis for the future development of functional foods targeting metabolic health.\n\nID: 42451146\nTitle: Dietary Polysaccharides and the Regulation of Blood Glucose and Lipid Parameters-A Narrative Review.\nAbstract: The increase in the prevalence of non-communicable diseases globally has been attributed in part to poor lifestyle choices, including unhealthy dietary habits. Dietary polysaccharides, including resistant starch and non-starch polysaccharides, have gained increasing attention due to their potential role in the regulation of glucose and lipid metabolism. Therefore, the aim of this review was to evaluate the role of dietary polysaccharides in the regulation of blood glucose and lipid parameters. A narrative review approach was adopted for this review. Searches were conducted through EBSCOHost and involved the following databases: Medline, APA PsycInfo, CINAHL Plus with Full Text, Psychology and Behavioural Sciences collection, Academic Search Premier and APA PsycArticles. Searches were conducted on 14 April 2026 and covered all records available from database inception to the search date. Search terms were combined using Boolean operators (AND/OR). The reference list of articles was also searched for more articles. Twenty-one studies from thirteen different countries were included in this review. Based on narrative synthesis, five themes were identified: the effects of dietary polysaccharides on glycaemia, insulin, lipids, energy intake and satiety/appetite. The findings demonstrated considerable heterogeneity across studies. While several studies reported improvements in fasting glucose, postprandial glucose, glycated haemoglobin and insulin responses following resistant starch and non-starch polysaccharide interventions, other studies found no significant effects on glycaemic control or insulin levels. Lipid outcomes were similarly inconsistent, although some studies reported reductions in total cholesterol and low density lipoprotein cholesterol. Effects on energy intake and satiety varied according to the type and physicochemical characteristics of the polysaccharide investigated. The findings of this review suggest that dietary polysaccharides may contribute to improvements in glucose control and lipid metabolism, although the magnitude and consistency of these effects vary across populations, intervention types and study designs. The most frequently reported beneficial findings related to blood glucose parameters, although substantial heterogeneity remained across studies. Further, well-designed studies, including randomised controlled trials with longer durations, are needed to fully establish the role of dietary polysaccharides in the control of blood glucose and lipid parameters.\n\nID: 42447970\nTitle: Human umbilical cord-derived mesenchymal stem cells ameliorate muscle dysfunction and metabolic dysregulation in the CuZnSOD null mouse model of sarcopenia.\nAbstract: Age-related sarcopenia is a progressive skeletal muscle disorder driven by oxidative stress and metabolic dysregulation. Cu/Zn superoxide dismutase-deficient (Sod1-/-) mice recapitulate key features of oxidative stress-induced muscle degeneration and provide a robust preclinical model for mechanistic and therapeutic studies. Here, we investigated whether systemic administration of human umbilical cord-derived mesenchymal stem cells (UC-MSCs) could modulate muscle function and metabolic homeostasis under both pathological and physiological conditions. In Sod1-/- mice, UC-MSC treatment significantly improved motor coordination and grip endurance, restored gastrocnemius myofiber number, markedly reduced mitochondrial reactive oxygen species production and catalase expression levels in skeletal muscle, and restored muscle ATP content. UC-MSCs also restored circulating insulin-like growth factor-1 (IGF-1) levels. Untargeted lipidomic profiling revealed profound depletion of lipid species in Sod1-/- muscle, particularly omega-3 fatty acids, which was selectively rescued by UC-MSC therapy, including restoration of \u03b1-linolenic acid, eicosapentaenoic acid, and docosahexaenoic acid, without substantial recovery of disrupted polar metabolic pathways such as aminoacyl-tRNA biosynthesis. In contrast, UC-MSC administration in wild-type mice induced a distinct metabolic remodeling characterized by reduced n-3 and n-6 fatty acid-associated lipid species and concomitant enrichment of fructose-related glycolytic intermediates, indicating a shift toward carbohydrate-based energy utilization in metabolically intact muscle. Together, these findings demonstrate that UC-MSCs function as context-dependent metabolic modulators, alleviating oxidative stress-induced sarcopenia through attenuation of oxidative stress, restoration of systemic IGF-1, and selective reprogramming of lipid metabolism, while dynamically adjusting energy metabolism in physiological skeletal muscle.\n\nID: 42445422\nTitle: A nomogram based on systemic inflammatory markers: development and validation for predicting postoperative overall survival in gastric cancer.\nAbstract: Gastric cancer (GC) remains a leading cause of cancer-related mortality worldwide. Emerging evidence links dysregulated lipid metabolism and chronic systemic inflammation to GC progression, and a bidirectional regulatory loop between lipid metabolism reprogramming and tumor inflammation; however, most prognostic studies have evaluated these markers in isolation. We hypothesized that integrating lipid derivatives and systemic inflammatory markers would provide complementary prognostic information. This study aimed to develop and validate a nomogram combining these markers to predict postoperative overall survival (OS) in patients with resectable GC. This retrospective study included GC patients who underwent radical gastrectomy at Affiliated Changshu Hospital of Nantong University, between January 2017 and December 2022. Inclusion criteria included radical surgery without preoperative anticancer treatment, and expected postoperative survival \u22653 months. Exclusion criteria included concurrent or prior malignancies, preoperative infection, or use of lipid-altering medications within 6 months. Fasting venous blood samples were collected preoperatively for routine blood, lipid profile, and coagulation tests using standardized automated analyzers. Fourteen composite inflammatory and lipid indices were calculated. Univariate and multivariate Cox regression analyses identified the independent predictors of overall survival (OS). A nomogram was constructed and validated using Harrell's concordance index (C-index) and calibration curves. A total of 295 patients with GC were included in the study. The patients were randomized into a training group (n=197) and a validation group (n=98) (2:1 ratio). Baseline characteristics were well balanced (all P>0.05), with only alcohol consumption rate differing significantly between groups (P=0.01). Univariate and multivariate Cox regression revealed that the pathological tumor-node-metastasis (pTNM) stage [hazard ratio (HR) =2.05; 95% confidence interval (CI): 1.09-3.84; P=0.03], systemic immune-inflammation index (SII) (HR =1.99; 95% CI: 1.08-3.68; P=0.03), systemic inflammatory response index (SIRI) (HR =1.88; 95% CI: 1.02-3.45; P=0.04), and fibrinogen-to-platelet ratio (FPR) (HR =2.14; 95% CI: 1.25-3.67; P=0.006) were independent predictors of postoperative OS, positively correlating with postoperative mortality. The nomogram integrating these four variables showed satisfactory discriminative ability, with C-indices of 0.699 in the training set and 0.719 in the validation set. Calibration curves demonstrated good agreement between the predicted and observed 1-, 2-, and 3-year OS rates. The nomogram based on the pTNM stage, SII, SIRI, and FPR exhibits moderate prognostic performance for postoperative OS in GC patients. It provides a comprehensive tool for clinicians to assess prognosis, guiding adjuvant therapy and individualized follow-up strategies.\n\nID: 42444221\nTitle: Genetic association of rs373001 polymorphism in mir-130b gene with susceptibility to dyslipidaemia and correlation with lipid profile.\nAbstract: To find the association and correlation of rs373001 polymorphism in micro-ribonucleic acid-130b gene with the risk of dyslipidaemia. The case-control study was conducted from April 2 to December 13, 2024, at the Department of Biochemistry and Molecular Biology, National University of Medical Sciences, Rawalpindi, Pakistan, in collaboration with the Chemical Pathology Laboratory, Army Medical College, Rawalpindi, and comprised dyslipidaemia cases and healthy controls. Genomic deoxyribonucleic acid extraction was done from blood samples using an organic method, and tetra-primer amplification refractory mutation system-polymerase chain reaction, followed by agarose gel electrophoresis. Data regarding lipid profile and fasting blood glucose was noted for all the participants. Data was analysed using SPSS 26. Of the 300 subjects, 150(50%) were in each of the two groups. There were 86(57%) males and 64(43%) females among the cases with mean age was 49.1\u00b111.6 years, and 76(52%) females and 72(48%) males with 43.3\u00b115.6 years among the controls. The rs373001 polymorphism of micro-ribonucleic acid-130b gene showed a C>T transition. The C allele (reference allele) frequency was n=123 (41%) in cases and n=144 (48%) in controls, while T allele (risk allele) frequency was n=177 (59%) in cases and n=156 (52%) in controls. The cases had 120(80%) CT, 1(0.7%) CC and 29(19.3%) TT genotypes, while the controls had 142(94.7%) CT, 1(0.7%) CC and 7(4.7%) TT genotypes. The TT genotype was a risk (adjusted odds ratio: 4.8, p<0.001) in recessive genetic model, while CT was protective (adjusted odds ratio: 0.2, p<0.001) in over-dominant model. A correlation was noted between genotypes and triglycerides levels (p=0.039) without confounders age and gender, but when adjusted with these confounders, no correlation was found (p>0.05). There was a positive association of the TT genotype of rs373001 polymorphism in micro-ribonucleic acid-130b gene with the risk of dyslipidaemia development in recessive genetic model and log-additive pattern of inheritance.\n\nID: 42440326\nTitle: Physical activity for the management of obesity in children up to the age of 9 years.\nAbstract: Childhood obesity is a major global public health concern. Although physical activity is recognised as an effective non-pharmacological intervention, most existing evidence synthesis has primarily focused on the role of physical activity in preventing obesity, with limited attention given to its effects on managing children with obesity. To synthesise evidence on the benefits and harms of physical activity for the management of obesity in children up to 9 years of age. We searched CENTRAL, MEDLINE, Embase, and two trial registries from 2012 to 2 June 2023, with an update on 4 December 2025. We also used Google Scholar to identify additional studies. We did not impose language or publication status restrictions. We included randomised controlled trials (RCTs) that investigated the effects of physical activity interventions of any frequency, mode (e.g. aerobic, resistance), or intensity, with a minimum intervention duration of 12 weeks, in children up to 9 years of age with obesity (as defined by the trialists) at baseline. Eligible comparators were standard care, waiting-list, no physical activity, or any other active interventions, such as comparisons of different physical activity parameters (e.g. duration, frequency, intensity). Critical outcomes: body mass index (BMI), BMI z-score, body weight, health-related quality of life, adiposity and fat distribution, glycaemia, and adverse events (minor and serious). Important outcomes: physical well-being, mental well-being, physical activity levels, blood pressure, hyperinsulinemia, resistance to insulin, alterations in lipid metabolism, presence of obesity-related comorbidities or any non-communicable diseases, obesity-associated disability, lipid hormones, alterations in hunger or satiety, disability, mortality, prevalence of obesity in adulthood, and access to health services. Pairs of review authors independently assessed the risk of bias in included studies using the original version of the Cochrane tool (RoB 1). We synthesised results using meta-analysis when appropriate. Given the clinical and statistical heterogeneity, we predominantly used a random-effects model alongside sensitivity analyses. When meta-analysis was not feasible, we employed synthesis without meta-analysis (SWiM) methods. We assessed the certainty of the evidence using the GRADE approach. We included four studies (five references, 517 children; female 46%; mean age ranged from 8.9 to 9.9) conducted in three countries (the USA, Brazil, and Iran). Three studies (75%) delivered the physical activity interventions in school settings. Three studies (75%) compared physical activity interventions with non-exercise controls, while one compared physical activity with a behaviour-changing intervention. The duration of physical activity interventions ranged from 12 to 32 weeks. We assessed three studies as having an overall high risk of bias. Physical activity interventions compared to control The evidence is very uncertain about the effect of physical activity interventions on BMI (mean difference (MD) -1.52 kg/m\u00b2, 95% confidence interval (CI) -2.74 to -0.29; I\u00b2 = 0%; 2 studies, 118 children; very low-certainty evidence), BMI z-scores (MD -0.10 z-score units, 95% CI -0.22 to 0.02; I\u00b2 = 29%; 1 study, 222 children; very low-certainty evidence), body weight (MD -0.86 kg, 95% CI -3.17 to 1.46; I\u00b2 = 0%; 2 studies, 118 children; very low-certainty evidence), health-related quality of life (MD -0.60 points, 95% CI -4.22 to 3.02; 1 study, 175 children; very low-certainty evidence), adiposity and fat distribution, assessed as body fat percentage (MD -1.23%, 95% CI -2.50 to 0.03; I\u00b2 = 0%; 3 studies, 456 children; very low-certainty evidence), minor adverse events (risk ratio (RR) 3.58, 95% CI 1.95 to 6.55; 1 study, 222 children; very low-certainty evidence), and serious adverse events (RR 1.08, 95% CI 0.10 to 11.76; 1 study, 222 children; very low-certainty evidence). No studies assessed glycaemia. Combined training (aquatic exercises) versus combined training (video game exercises) The evidence is very uncertain about the effect of combined training in an aquatic setting compared to video-game-based combined training on BMI (MD -0.90 kg/m\u00b2, 95% CI -3.21 to 1.41; 1 study, 39 children; very low-certainty evidence), BMI at 4-week follow-up (MD 0.03 kg/m\u00b2, 95% CI -2.54 to 2.60; 1 study, 39 children; very low-certainty evidence), body weight (MD -1.30 kg, 95% CI -5.66 to 3.06; 1 study, 39 children; very low-certainty evidence), and body weight at 4-week follow-up (MD -0.70 kg, 95% CI -5.70 to 4.30; 1 study, 39 children; very low-certainty evidence). This study did not assess the other critical outcomes. Low-dose versus high-dose combined training The evidence is very uncertain about the effect of low-dose versus high-dose combined training on BMI z-scores (MD 0.12 z-score units, 95% CI 0.10 to 0.14; 1 study, 144 children; very low-certainty evidence), adiposity and fat distribution, assessed as body fat percentage (MD 1.07%, 95% CI -0.74 to 2.88; 1 study, 144 children; very low-certainty evidence), glycaemia, assessed as fasting glucose level (MD -0.50 mg/dL, 95% CI -2.77 to 1.77; 1 study, 144 children; very low-certainty evidence), minor adverse events (RR 0.91, 95% CI 0.64 to 1.30; 1 study, 144 children; very low-certainty evidence), and serious adverse events (RR 3.08, 95% CI 0.13 to 74.45; 1 study, 144 children; very low-certainty evidence). This study did not assess the other critical outcomes. The evidence from four randomised studies on the effects of physical activity interventions in children aged 0 to 9 with obesity is of very low certainty. Serious methodological limitations, clinical heterogeneity, small-study effects, and imprecise results constrained this evidence base. Important knowledge gaps remain because none of the included RCTs enroled children with disabilities. The RCTs provided little information on contextual factors. Future high-quality and better-reported RCTs will likely change our findings.

Although CSF1R inhibitor-based studies have uncovered important roles for microglia in processes, such as anesthesia, addiction, and obesity, whether the resulting phenotypes reflect microglial depletion alone remains increasingly debated. Our previous work has shown that PLX5622 activates hepatic constitutive androstane receptor (CAR)-dependent xenobiotic metabolism, altering the metabolism of anesthetics and addictive drugs, and amplifying apparent microglial phenotypes. Whether other CSF1R inhibitors, particularly the FDA-approved PLX3397, exert systemic metabolic effects that may influence the interpretation of brain phenotypes remains unknown. Here, we demonstrate that PLX3397 exerts hepatic metabolic effects that are mechanistically distinct from those induced by PLX5622. Although PLX3397 only weakly affects xenobiotic metabolism, it markedly enhances endogenous hepatic lipid metabolism, inducing a fasting-like state characterized by increased lipid utilization and ketogenesis despite the absence of nutrient deprivation. By uncovering previously unrecognized peripheral effects of PLX3397, our findings identify brain-periphery interactions as a potential source of confounding in studies of microglial function. These results suggest that systemic metabolic effects should be carefully considered when interpreting neural or behavioral phenotypes in pharmacological microglia depletion paradigms.\n\nID: 42435134\nTitle: The metabolic effects of glucocorticoid replacement therapy in patients with secondary adrenal insufficiency due to hypothalamic-pituitary diseases: results from a retrospective and longitudinal study.\nAbstract: Secondary adrenal insufficiency (SAI) is a complex endocrine disorder. Glucocorticoid (GC) replacement therapy is crucial for ensuring patient survival and guaranteeing an adequate quality of life. GC replacement therapy requires a balance between undertreatment, with the consequent risk of adrenal crisis, and overtreatment, which can have long-term effects on the metabolic and cardiovascular systems. We conducted a retrospective, longitudinal, observational study on 140 patients affected by pituitary disease with at least 3\u00a0years of follow-up. Patients were consecutively included in the study with a ratio 1:1, considering patients affected by SAI and who were therefore on GCs replacement therapy, and patients with pituitary disease without SAI (controls). Worsening of glucose metabolism occurred in 29 patients with SAI (64.4%) and in 16 controls (35.6%, p\u2009=\u20090.019). Worsening of lipid metabolism occurred in 52 patients with SAI (56.5%) and in 40 controls (43.5% p\u2009=\u20090.033). GC replacement therapy (p\u2009=\u20090.014, OR: 2.3, 95%IC: 1.1-4.9), higher fasting glycaemia at baseline (p\u2009=\u20090.04, OR: 7.6, 95%IC: 2.3-25.4), IGT/T2DM at baseline (p\u2009=\u20090.016, OR: 8.6, 95%IC: 0.8-57) were the main risk factors for the worsening of glucose metabolism at 3-year follow-up. TSH deficit remained the only risk factor for the worsening of lipid profile (p\u2009<\u20090.001, OR: 2.9, 95%IC: 1.3-6.5). Our study proved that GCs replacement therapy may be associated with a worsening of glucose metabolism, particularly in patients already affected by IGT/T2DM. Tailored and holistic management is essential for the management of GCs replacement therapy, in patients with other metabolic disorders and pituitary hormone deficits.\n\nID: 42432891\nTitle: Risk factors for distal symmetric polyneuropathy in patients with type 2 diabetes mellitus: A retrospective study.\nAbstract: The pathophysiology of distal symmetric polyneuropathy (DSPN) is multifactorial, involving chronic hyperglycemia, oxidative stress, accumulation of advanced glycation end products, impaired microvascular perfusion, metabolic toxicity, and nutritional deficiencies. Although previous studies have identified various risk factors, substantial heterogeneity exists across regions and populations, and most investigations have not comprehensively integrated metabolic markers, microvascular damage, and electrophysiological data. Therefore, a multidimensional assessment of DSPN risk factors is essential to improve early screening and risk-prediction strategies. A total of 120 patients with type 2 diabetes mellitus (T2DM) were enrolled, including 60 with DSPN and 60 without. Compared with the non-DSPN group, patients with DSPN were older, had longer diabetes duration, and demonstrated a higher prevalence of smoking, diabetic retinopathy (DR), and diabetic kidney disease. DSPN patients exhibited poorer glycemic control (higher fasting blood glucose, 2-hour postprandial blood glucose, and hemoglobin A1c [HbA1c]), more pronounced dyslipidemia (elevated triglycerides, reduced high-density lipoprotein cholesterol), and abnormalities in inflammatory and nutritional markers (elevated C-reactive protein and homocysteine [HCY], reduced vitamin B12). Renal function parameters (serum creatinine, estimated glomerular filtration rate, urine albumin-creatinine ratio) indicated more severe microvascular impairment in the DSPN group. Electrophysiological testing showed reduced sensory and motor nerve conduction velocities, decreased amplitudes, and prolonged latencies. Multivariable logistic regression identified diabetes duration, DR, elevated HbA1c, elevated HCY, and reduced sural nerve amplitude as independent risk factors for DSPN. Longer diabetes duration, DR, elevated HbA1c, elevated HCY levels, and reduced sural nerve amplitude were independently associated with DSPN in patients with T2DM. These findings may contribute to improved risk stratification and support further investigation of multidimensional approaches for early DSPN identification. This single-center retrospective cohort study included patients with T2DM treated at our hospital between June 2023 and June 2025. DSPN was diagnosed based on American Diabetes Association, European Federation of Neurological Societies, and diabetic neuropathy working group criteria using a combination of clinical symptoms, neurological signs, and nerve conduction studies. Demographic characteristics, lifestyle factors, diabetes-related complications, glucose and lipid metabolism indicators, renal function, inflammatory and nutritional markers, and electrophysiological parameters were collected. Group differences were assessed using the t-test, Mann-Whitney U test, or \u03c72 test. Variables with P\u2005<\u2005.10 in univariate analyses were entered into multivariable logistic regression to identify independent risk factors for DSPN. Sensitivity analyses and collinearity diagnostics were performed to assess the robustness of the findings.\n\nID: 42432438\nTitle: Phenylacetic Acid, a Gut Microbially Produced Metabolite, Reduces Atherosclerosis Burden and Impacts Host Lipid Homeostasis.\nAbstract: Gut microbial metabolism of dietary phenylalanine produces phenylacetic acid (PAA), followed by the host conversion to phenylacetylglutamine in humans and phenylacetylglycine in mice. Phenylacetylglutamine was linked to cardiovascular disease risk in multiple clinical studies, yet whether the microbial pathways leading to PAA/phenylacetylglutamine/phenylacetylglycine formation influence atherosclerosis progression within the host remains elusive. Atheroprone Apoe-/- mice on a Western diet were provided with a gut microbial metabolite PAA to investigate its effects on host cardiometabolic health. Circulating levels of phenylacetylglutamine and phenylacetylglycine were increased by the treatment without affecting circulating cholesterol or inflammatory cytokines. In male mice, PAA elevated triglycerides and fasting glucose. PAA decreased the total atherosclerotic plaque burden within the descending and abdominal aortas of both sexes and within brachiocephalic arteries in male mice without affecting plaque stability indices. PAA altered gut microbial composition but did not markedly shift production of established atherosclerosis-related microbial metabolites, aside from a modest rise in indoxyl sulfate in female mice. Furthermore, PAA treatment decreased circulating levels of acyl- and free carnitines through reduced availability of their biosynthetic precursors and upregulated expression of genes involved in peroxisomal lipid metabolism. These results offer new insights into the impact of gut-microbial metabolism of phenylalanine on host metabolism and atherosclerosis progression. Our findings suggest that clinical associations between phenylacetylglutamine and cardiovascular disease risk are unlikely to be driven by increased atherosclerosis.\n\nID: 42431858\nTitle: Acid ceramidase modulates the lipid profile and exacerbates sensitivity to ferroptosis in WI-38 replicative senescent cells.\nAbstract: Cellular senescence, a complex biological process characterized by irreversible cell cycle arrest and the senescence-associated secretory phenotype, has emerged as a critical target for therapeutic development for age-related diseases. Ferroptosis, an iron-dependent regulated cell death pathway driven by the accumulation of lipid peroxidation in cell membranes, has been implicated in age-related disorders. This study investigated the relationship between cellular senescence and ferroptosis. Using human fetal lung WI-38 fibroblasts induced to senesce via replicative exhaustion, we report a novel role for acid ceramidase (ACase), which breaks down ceramides into sphingosine and free fatty acids, in regulating the sensitivity of senescent cells to RSL3-induced lipid peroxidation and ferroptosis through the modulation of polyunsaturated fatty acid composition of membrane phospholipids. Furthermore, we demonstrate a cell non-autonomous paracrine sensitization of non-senescent cells to ferroptosis by senescent cells. Together, these findings unveil ACase as a novel regulator of the ferroptosis pathway and open promising therapeutic avenues for targeting senescence-linked disorders and advancing healthy aging strategies.\n\nID: 42428496\nTitle: The efficacy and safety of Chaihu guizhi ganjiang tang for type 2 diabetes mellitus: a systematic review and meta-analysis.\nAbstract: The pathological mechanisms of type 2 diabetes mellitus (T2DM) are complex and necessitate multi-target intervention strategies. Chaihu Guizhi Ganjiang Tang (CHGZGJT), a classical formula derived from the ancient canonical text Shanghan Lun (Treatise on Cold Damage Diseases), has been reported to improve glucose and lipid metabolism as well as islet function in patients with T2DM. However, a quantitative evidence-based evaluation is currently lacking. This study aimed to systematically evaluate the overall efficacy and safety of CHGZGJT. This study was registered on the PROSPERO platform. Eight Chinese and English databases and two clinical trial registries were systematically searched, and 12 clinical controlled trials involving a total of 883 patients were ultimately included. Meta-analysis were performed using R software to assess efficacy and safety. The meta-analysis suggested that CHGZGJT combined with conventional treatment significantly reduced glycated hemoglobin (HbA1c, MD = -0.69%), fasting plasma glucose (FPG, MD = -0.86\u00a0mmol/L), and 2-h postprandial glucose (2hPG, MD = -0.74\u00a0mmol/L) in patients with T2DM. At the mechanistic level, this regimen significantly decreased fasting insulin (FINS, MD = -2.08\u00a0\u00b5IU/mL) and the homeostasis model assessment of insulin resistance (HOMA-IR, MD = -0.79), improved islet \u03b2-cell function (HOMA-\u03b2, MD = 5.13), and lowered total cholesterol, triglyceride, and low-density lipoprotein cholesterol levels, with a lower risk of adverse events (RR = 0.44). CHGZGJT may improve glycemic control, insulin resistance, \u03b2-cell function, and the lipid profile in patients with T2DM, with a favorable safety profile for short-term administration. However, the quality of evidence from the included studies was low to moderate, and high-quality clinical trials are still warranted to further verify its long-term efficacy and safety.\n\nID: 42427207\nTitle: Cyclocarya paliurus Polysaccharides Attenuate High-Fat Diet-Induced Metabolic Dysfunction via Gut Microbiota Remodeling.\nAbstract: Alterations in gut microbiota composition are closely associated with obesity and metabolic disorders. Cyclocarya paliurus polysaccharides (CCPP) have been shown to improve lipid metabolism and modulate the gut microbiota; however, mechanistic evidence remains limited and may vary depending on preparation methods. This study investigated whether a crude polysaccharide-enriched Cyclocarya paliurus preparation alleviates high-fat diet-induced metabolic dysfunction and is associated with gut microbiota remodeling. Male C57BL/6\u2009J mice were randomized into three groups: normal diet (ND), high-fat diet (HFD), and HFD supplemented with CCPP for 12\u2009weeks. Serum metabolic parameters were measured; intestinal inflammatory cytokine transcripts were assessed by qRT-PCR; and cecal microbiota composition was analyzed by 16S rRNA gene sequencing. Additionally, fecal microbiota transplantation (FMT) was performed by transferring microbiota from CCPP-treated donors to antibiotic-pretreated HFD-induced recipients for 8\u2009weeks. CCPP attenuated HFD-induced body weight gain and reduced subcutaneous and visceral adipose tissue mass. CCPP significantly improved serum total cholesterol and low-density lipoprotein cholesterol (LDL-C) and reduced fasting glucose. Cecal 16S rRNA gene profiling showed that CCPP reshaped the gut dysbiosis associated with a HFD and enriched microbial taxa that are commonly linked to carbohydrate fermentation. These taxa specifically include Lachnospiraceae-related microbial taxa and Ileibacterium. Importantly, FMT from CCPP-treated donors recapitulated these metabolic improvements, confirming that the benefits of CCPP were microbiota-dependent. CCPP mitigates obesity and metabolic dysfunction by remodeling the gut microbiota, particularly by enriching short-chain fatty acid-producing taxa. These findings highlight CCPP as a potential microbiota-targeted therapeutic agent for metabolic disorders.\n\nID: 42422382\nTitle: The impact of maximal fat oxidation intensity exercise on glucose and lipid metabolism in individuals with overweight or obesity: A systematic review and meta-analysis.\nAbstract: This study provides the first quantitative synthesis evaluating the chronic effects of FATmax training on glucose and lipid metabolism in individuals with overweight or obesity, while systematically exploring the moderating roles of participant characteristics and intervention protocols. A comprehensive search of seven databases (e.g., PubMed, Web of Science) was conducted up to August 2025, identifying 24 controlled trials involving 638 participants. Random-effects meta-analyses showed that FATmax training produced significant improvements in multiple glycolipid metabolic markers. Specifically, large standardized reductions were observed in fasting plasma glucose (Hedges' g = -1.05), insulin resistance (Hedges' g = -0.82), and fasting insulin (Hedges' g = -0.75), alongside moderate improvements in triglycerides (Hedges' g = -0.55), total cholesterol (Hedges' g = -0.23), and high-density lipoprotein cholesterol (HDL-C; Hedges' g = 0.51). Notably, the large standardized effects on glycemic markers suggest potentially clinically meaningful improvements in glycemic control. Subgroup analyses indicated that HDL-C adaptations were significantly enhanced in male participants, weight-bearing modalities, and protocols incorporating warm-up sessions or concurrent dietary restriction (p < 0.05). Furthermore, meta-regression identified baseline HDL-C (\u03b2= -2.955), exercise intensity (\u03b2 = 0.053), and session duration (\u03b2 = 0.058) as significant predictors of HDL-C improvement. Crucially, we derive the first clinically actionable, personalized thresholds from interaction analyses: for individuals with low baseline HDL-C (\u2264 1.36 mmol/L), efficacy is maximized when session duration exceeds 60 minutes (Hedges' g = 1.19) or intensity surpasses 42.2% V \u02d9 O2max (Hedges' g = 1.10); whereas for those with higher baseline levels, extending duration (\u2265 60 min) is the primary requisite for significant benefits (Hedges' g = 0.61). In conclusion, FATmax training produces significant and potentially clinically meaningful improvements in glucose and lipid metabolism in individuals with overweight or obesity. These effects are modulated by individual characteristics and intervention parameters. Future research should prioritize standardized FATmax determination protocols and diverse populations to validate these personalized prescription parameters.\n\nID: 42420973\nTitle: Efficacy of probiotic and synbiotic supplementation on metabolic and endocrine parameters in polycystic ovary syndrome: a meta-analysis of randomized controlled trials.\nAbstract: This systematic review and meta-analysis aimed to evaluate the effects of probiotic and synbiotic supplementation on insulin resistance, reproductive endocrine function, lipid metabolism, inflammatory response, anthropometric parameters, and oxidative stress in patients with polycystic ovary syndrome (PCOS). Databases including PubMed, Web of Science, the Cochrane Library and Embase were systematically searched from inception to March 19, 2026. The Cochrane Risk of Bias Assessment Tool (RoB 2.0) was used for study quality evaluation. Meta-analysis was conducted with RevMan 5.4 and Stata 17.0. The study was prospectively registered in PROSPERO (CRD420251125178) and reported following PRISMA guidelines. Eleven randomized controlled trials involving 780 participants were included. Probiotic and synbiotic supplementation significantly reduced fasting insulin (MD\u2009=\u2009-\u20091.41, 95% CI: -2.76 to -\u20090.05), total testosterone (MD\u2009=\u2009-\u20090.19, 95% CI: -0.25 to -\u20090.12), triglycerides (MD\u2009=\u2009-\u200912.28, 95% CI: -24.21 to -\u20090.35), low-density lipoprotein cholesterol (MD\u2009=\u2009-\u20096.19, 95% CI: -10.08 to -\u20092.30), BMI (MD\u2009=\u2009-\u20090.49, 95% CI: -0.88 to -\u20090.10), and body weight (MD\u2009=\u2009-\u20091.07, 95% CI: -2.08 to -\u20090.05), while increasing high-density lipoprotein cholesterol (MD\u2009=\u20091.73, 95% CI: 0.40 to 3.06) and total antioxidant capacity (MD\u2009=\u2009124.02, 95% CI: 40.49 to 207.54). No significant effects were observed for fasting glucose, HOMA-IR, QUICKI, FSH, LH, SHBG, DHEAS, total cholesterol, C-reactive protein, waist circumference, or hip circumference. The single prebiotic trial contributed only to the meta-analyses of BMI, body weight, and waist circumference. According to the GRADE framework, the certainty of evidence was high for Testosterone, TG, LDL\u2011C, HDL\u2011C, BMI, and body weight, moderate for fasting insulin, and low for total antioxidant capacity. Probiotic or synbiotic supplementation significantly improves multiple clinical parameters in women with PCOS, including reductions in fasting insulin, total testosterone, triglycerides, LDL cholesterol, BMI, and body weight, while increasing HDL cholesterol and total antioxidant capacity. However, the effects on fasting blood glucose, HOMA-IR, and certain sex hormones remain unclear and require further validation. The single available prebiotic trial showed benefits only for BMI and body weight, but its evidence is limited. Not applicable.\n\nID: 42414899\nTitle: Ketogenic diets and cardiovascular health balancing metabolic benefits against lipid-related risk.\nAbstract: The cardiovascular impact of ketogenic diets (KD) remains debated. In this review, KD refers to adult dietary interventions intended to induce nutritional ketosis through marked carbohydrate restriction, while acknowledging that ketogenic diet therapy (KDT) is a broader umbrella term encompassing several protocol variants. We systematically searched PubMed, Embase, Web of Science, and the Cochrane Library from inception to March 2026, and we additionally searched gray literature sources (ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform, medRxiv, conference proceedings, and reference lists). Eligible studies included randomized controlled trials (RCTs), prospective cohorts, and observational studies of adult KD interventions (generally\u2009<\u200910% of energy from carbohydrate or <\u200950\u00a0g/day). Primary outcomes were lipid changes; secondary outcomes included glycemia, anthropometrics, and blood pressure; exploratory outcomes were mortality and atherosclerosis. Random-effects meta-analyses generated pooled estimates. The protocol was not prospectively registered. Twenty-four studies (20 RCTs, 2 prospective cohorts, 1 non-randomized clinical trial, and 1 pilot intervention; >47,000 participants) were included. Compared with control diets, KD increased low-density lipoprotein cholesterol (LDL-C) (mean difference [MD]\u2009+\u200912.2\u00a0mg/dL, 95% CI 7.5 to 16.9; I2\u2009=\u200967.7%) and total cholesterol, while high-density lipoprotein cholesterol (HDL-C) rose modestly. Triglycerides decreased overall (MD -16.1\u00a0mg/dL, 95% CI -20.3 to -11.8; I2\u2009=\u200917.1%). KD also improved fasting glucose, glycated hemoglobin, body weight, body mass index, and systolic blood pressure. Cohort evidence suggested lower all-cause mortality but no clear reduction in cardiovascular mortality. Imaging evidence for atherosclerosis was limited and mixed. KD was associated with improvements in adiposity, glycemic control, and blood pressure, but also with higher LDL-C and total cholesterol. Evidence for clinical cardiovascular endpoints remains limited, mixed, and mostly low certainty, supporting individualized risk-benefit assessment rather than universal adoption of KD.\n\nID: 42413662\nTitle: Diet, microbiota, and lipidomics: How fatty acids shape the endocannabinoidome and host metabolism.\nAbstract: The endocannabinoidome (eCBome) is a complex lipid signaling network that integrates metabolic, immune, and neurobehavioral processes in response to environmental cues. Dietary lipids and gut microbiota have emerged as major modulators of its activity and signaling tone. Intake of specific fatty acids, including the monounsaturated oleic acid, the omega-6 polyunsaturated linoleic acid, and omega-3 polyunsaturated fatty acids, influences the eCBome not only by serving as structural precursors of bioactive lipid mediators, but also by altering the relative abundance of these mediators through changes in substrate availability, enzymatic competition, and receptor-mediated feedback loops. Concurrently, gut microbiota shape host eCBome signaling by regulating lipid metabolism, inflammatory tone, and intestinal barrier integrity, while eCBome mediators reciprocally modulate microbial composition and function. Dysregulation of this complex diet-microbiota-eCBome interplay has been implicated in the pathogenesis of metabolic disorders, chronic inflammation, and neuropsychiatric conditions. In this review, we critically examine the molecular mechanisms underlying the interactions between dietary lipid composition, gut microbial ecology, and eCBome signaling. We discuss the implications for human health and highlight emerging diet-based therapeutic strategies targeting this axis.\n\nID: 42410437\nTitle: Association between glycolipid metabolism 7 factors (GLM7) and pregnancy loss in women aged 18-35\u00a0years: evidence from NHANES 2009-2018.\nAbstract: Growing evidence suggests that metabolic disturbances underlie pregnancy losses, imposing a substantial public health burden among young women of reproductive age. Glycolipid metabolism 7 factors (GLM7) is a composite glycolipid metabolism index derived from routinely measured metabolic indicators; however, its relevance to pregnancy loss in young women remains unexamined. The present study analyzed publicly available data from the 2009-2018 National Health and Nutrition Examination Survey (NHANES) cycles. Participants were categorized as having no pregnancy loss, single pregnancy loss, or recurrent pregnancy loss (\u2265\u20092 losses). GLM7 was calculated as the logarithm of the product of age, body mass index, fasting blood glucose, fasting insulin, triglycerides, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol levels. The association between GLM7 and pregnancy loss categories was evaluated, potential dose-response patterns were explored, and effect modification by selected sociodemographic and behavioral factors was assessed. Of the 736 women included in the analysis, 300 (37%) reported a history of pregnancy loss. In binary analyses, higher GLM7 was initially associated with pregnancy loss (OR\u2009=\u20091.21, 95% CI: 1.03-1.44); however, the association was attenuated after adjustment for the number of pregnancies (OR\u2009=\u20091.19, 95% CI: 0.99-1.44). In multinomial analyses, higher GLM7 levels were not significantly associated with single pregnancy loss. In contrast, higher GLM7 remained independently associated with recurrent pregnancy loss after adjustment for all covariates (OR\u2009=\u20091.17, 95% CI: 1.02-1.42; P\u2009=\u20090.046). Women in the second to fourth quartiles had significantly higher odds of recurrent pregnancy loss than those in the lowest quartile. No significant nonlinearity was observed in the association between GLM7 and recurrent pregnancy loss (P for nonlinearity\u2009=\u20090.265). No statistically significant interaction was observed across the subgroups. In this nationally representative sample of U.S. women aged 18-35\u00a0years, higher GLM7 levels were more robustly associated with recurrent rather than isolated pregnancy loss. The findings suggested that cumulative glycolipid metabolic burden may be particularly relevant to repeated reproductive failures and serve as indicators to improved strategies for early reproductive risk identification and preventive healthcare for women.\n\nID: 42403180\nTitle: Potential of marine dinoflagellates Amphidinium carterae and Prorocentrum minimum as fatty acids producers: A comparative transcriptome and fatty acid profiling study.\nAbstract: Marine dinoflagellates are gaining attention as sustainable bioresource for polyunsaturated fatty acids (PUFAs), particularly omega-3 such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). In the present study, we analyzed the FAs and transcriptomic profiles of marine dinoflagellates Amphidinium carterae (D-044) and Prorocentrum minimum (D-127) to evaluate their potential as FAs producers. Gas chromatography-FA methyl ester (GC-FAME) analysis showed that A. carterae is a superior omega-3 producer, yielding a total FA content of 67.6 mg/g DW. DHA accounted for 26.7% of the total FAME profile, which is significantly higher than that of P. minimum (18.1 mg/g DW; DHA 13.1%). Gene Ontology (GO) annotation revealed genes related to FAs and lipid metabolism in A. carterae (1,217 genes) and in P. minimum (2,317 genes), which provide a molecular basis for dinoflagellates with high lipid productivity. Notably, three lipid droplet-associated hydrolase (LDAH) genes with diverse evolutionary origins were identified from A. carterae. These findings suggest a potential expansion of the genetic repertoire related to lipid storage and metabolism, highlighting A. carterae and LDAH as candidates for future biotechnological applications and microalgal metabolic engineering.\n\nID: 42399715\nTitle: Comparison of Standard Clinical Pathology Parameter Values in Fasted and Fed Rats and Non-human Primates.\nAbstract: The impact of non-fasting on clinical pathology parameters in pharmacologic safety assessment has been incompletely characterized. The aim of this study was to characterize changes in hematology, coagulation, and clinical chemistry parameters between healthy fasted and fed rats and macaques. Adult Sprague-Dawley rats (41 males, 40 females) and cynomolgus macaques (10 per sex) were sampled after free access to food and after 8 hours of fasting. Fed rats demonstrated lower reticulocyte and neutrophil counts in males only. Higher alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase activities and higher glucose, triglyceride, cholesterol, and globulin concentrations were observed with lower urea nitrogen, albumin, and phosphorus concentrations in fed compared with fasted rats of both sexes. Fed macaques of both sexes demonstrated higher triglyceride concentrations and lower phosphorus and total bilirubin concentrations. All changes in fed compared with fasted rats and macaques were considered minor. Non-fasting did not impact coagulation parameters in rats and macaques or hematology parameters in macaques. This study supports that non-fasting has a minimal impact on standard clinical pathology parameters in Sprague-Dawley rats and cynomolgus macaques; however, fasting is still recommended when there are anticipated effects on glucose and lipid metabolism or on endocrine systems related to energy metabolism.\n\nID: 42397637\nTitle: Metabolomic signature reveals dysregulated lipoprotein profile in m.3243A>G carriers: a case-control study.\nAbstract: The pathogenic mitochondrial gene variant m.3243A>G disrupts oxidative phosphorylation and is associated with insulin resistance, both of which may be linked to unfavorable lipid metabolism. However, the metabolic alterations in m.3243A>G carriers, including what differentiates those with and without diabetes, remain incompletely understood. To investigate metabolomic profiles in fasting serum and urine samples from m.3243A>G carriers compared to healthy controls. Metabolomic profiling of serum and urine samples using nuclear magnetic resonance-based metabolomics in m.3243A>G carriers (n\u2009=\u200928) was compared to healthy controls matched for age and sex. Additionally, profiles from m.3243A>G carriers with diabetes (n\u2009=\u200916) were compared with carriers without diabetes (n\u2009=\u200912) to identify potential metabolites associated with the presence of diabetes. Twenty-five metabolites in serum and 16 in urine were identified as metabolites separating m.3243A>G carriers from healthy controls. The m.3243A>G carriers presented with increased triglycerides across lipoprotein particles and altered very-low-density lipoprotein concentrations and composition. In addition, there were alterations in metabolites from a number of metabolic pathways, including glycolysis, the tricarboxylic acid cycle, glutathione, one-carbon, and nucleotide metabolism. A three metabolite-urine signature (uracil, hypoxanthine, and 1-methylnicotinamide) demonstrated discriminating potential between m.3243A>G carriers and controls in exploratory machine learning analyses (area under the curve values 0.94-0.99 and cross-validation prediction of 0.81-0.93). Among m.3243A>G carriers, branched-chain amino acids were higher in individuals with diabetes compared with carriers without diabetes. Dysregulated lipoprotein metabolism represents a significant metabolic fingerprint of m.3243A>G carriers. Furthermore, higher levels of branched-chain amino acids may be associated with the presence of diabetes.\n\nID: 42393878\nTitle: Low Glycemic Index Diets on Glycemic and Lipid Control Across Diverse Populations: A Systematic Review and Meta-Analysis.\nAbstract: Although low-Glycemic-Index (low-GI) diets are proposed to improve glucose balance and lipid metabolism, findings from Randomized Controlled Trials (RCTs) remain inconsistent. To comprehensively evaluate the overall effects of low-GI diets on glycemic and lipid profiles across diverse populations and to identify potential differences in outcomes among subgroups. This systematic review and meta-analysis, conducted following PRISMA guidelines, searched PubMed, Embase, Cochrane Library, and Web of Science through April 2025. Weighted Mean Difference (WMD) with 95% Confidence Interval (CI) was calculated. Subgroup and sensitivity analyses explored heterogeneity and robustness. Twenty-five RCTs involving 1,973 participants (12-75 years) were included. Low-GI diets significantly reduced fasting blood glucose (FBG; -0.19 mmol/L, p = 0.04), glycated hemoglobin (HbA1c; -0.22%, p < 0.01), and low-density lipoprotein cholesterol (LDL-C; -0.15 mmol/L, p < 0.01) compared with control diets. Although not statistically significant, low-GI diets tended to increase High-Density Lipoprotein Cholesterol (HDL-C) and reduce Fasting Insulin (FI), Homeostasis Model Assessment of Insulin Resistance (HOMA-IR), Triglycerides (TG), and Total Cholesterol (TC). Subgroup analyses revealed stronger benefits in Type 2 Diabetes Mellitus (T2DM), individuals with baseline FBG \u2265 6.1 mmol/L, trials with intervention duration \u2265 12 weeks, and people in the Asia-Pacific region. Sensitivity analyses provided confirmation of the reliability of these outcomes. Low-GI diets improve glycemic control and modestly lower LDL-C, particularly in metabolically high-risk populations and with sustained intervention. These results highlight low-- GI diets as a practical nutritional strategy for metabolic health, while suggesting that baseline glucose status, intervention length, and population characteristics influence their effectiveness.\n\nID: 42564435\nTitle: Germinated Brown Rice: A Natural Source of Bioactive Compounds Boosting Human Health.\nAbstract: Germinated brown rice (GBR) has gained considerable attention as a functional food due to both nutritional and bioactive profiles as well as health-promoting properties. The present narrative review is aimed at summarizing and discussing available research on GBR, focusing on bioactive composition and potential to support human well-being. Based on available data, the germination process of brown rice enhances the bioavailability of key bioactive compounds, including polyphenols, \u03b3-aminobutyric acid, \u03b3-oryzanol, vitamins, and dietary fibers. Additionally, a substantial body of evidence supports the ability of GBR to exert beneficial physiological effects on the host, such as modulation of lipid and glucose metabolism, antioxidant and anti-inflammatory activities, and positive influences on gut microbiota composition. The use of GBR in formulating functional foods and nutraceutical supplements further highlights its versatility as a promising strategy in supporting human well-being.\n\nID: 42564155\nTitle: Evening chronotype is associated with higher circulating pyruvate levels in adults.\nAbstract: Chronotype reflects interindividual differences in the circadian timing system. Animal studies suggest reduced mitochondrial oxidative metabolism and tricarboxylic acid (TCA) cycle activity in individuals with an evening chronotype; however, human evidence linking chronotype to mitochondrial metabolic alterations remains limited. This cross-sectional study examined whether chronotype is associated with differences in circulating TCA-related metabolites, including pyruvate, lactate, and citrate. A total of 272 adults from the 2022 Gangwon Obesity and Metabolic Syndrome Cohort were classified as having morning (\u226518), intermediate (12-17), or evening (\u226411) chronotype using the reduced Morningness-Eveningness Questionnaire. Fasting serum concentrations of pyruvate, lactate, and citrate were measured. Associations were examined using general linear models adjusted for fasting status; demographic, socioeconomic, and lifestyle factors; as well as body mass index. Sensitivity analyses excluded participants taking metabolic disease-related medications. Major clinical and metabolic indicators did not differ across chronotypes. Serum pyruvate concentrations were higher in the evening chronotype group than in the morning chronotype group across all adjusted models (p\u202f<\u202f0.048), whereas lactate and citrate concentrations did not differ. These findings remained consistent in sensitivity analyses excluding participants with metabolic diseases (p\u202f=\u202f0.006-0.010). Across analyses that included and excluded participants using metabolic disease-related medications, evening chronotype was consistently associated with higher circulating pyruvate concentrations, a key metabolic branch point downstream of glycolysis. These findings suggest chronotype-related differences in pyruvate metabolism, with potential implications for metabolic regulation.\n\nID: 42563800\nTitle: [Association between metabolic syndrome and autonomic nervous system activity in middle-aged menopausal women in South Korea: a cross-sectional study].\nAbstract: This study aimed to investigate the association between metabolic syndrome and autonomic nervous system activity in middle-aged postmenopausal women. In addition, it explored the clinical applicability of heart rate variability (HRV) as a physiological marker for the early diagnosis and management of metabolic disorders. This study was conducted as a secondary data analysis using health examination data. The dataset included 276 postmenopausal women aged 50 to 65 years. Autonomic nervous system activity was evaluated using HRV indices, including standard deviation of the normal-to-normal interval (SDNN), total power (TP), low frequency (LF), and high frequency (HF). Statistical analyses were performed using the t-test, chi-square test, and Pearson correlation analysis with SPSS version 26.0. The prevalence of metabolic syndrome among the participants was 21.4%. The LF index was significantly lower in the metabolic syndrome group compared with the normal group (t = 2.74, p = .007). Additionally, fasting blood glucose showed significant negative correlations with SDNN (r = -.16, p = .010), TP (r = -.21, p < .001), LF (r = -.17, p = .004), and HF (r = -.18, p = .003). A reduction in HRV, particularly in LF, may serve as an indicator of metabolic syndrome in postmenopausal women. Because autonomic dysfunction can potentially be improved through nursing interventions, the use of HRV-based monitoring and personalized nursing strategies should be considered in clinical practice to help prevent the onset of metabolic syndrome in postmenopausal women.\n\nID: 42563722\nTitle: Factors influencing metabolic syndrome in adult workers: an analysis of data from the 2022 Korea National Health and Nutrition Examination Survey.\nAbstract: This study analyzed the prevalence of metabolic syndrome and influencing factors among adult workers aged 19 to 64. Data from the ninth Korea National Health and Nutrition Examination Survey conducted in 2022 were utilized. The sample comprised 685 individuals who had measurements of fasting glucose, triglycerides, high-density lipoprotein cholesterol, blood pressure, and waist circumference, which are necessary to diagnose metabolic syndrome. Data analysis was performed using SPSS 26.0, and complex sample logistic regression was conducted to identify factors influencing metabolic syndrome. Among the participants, 34.3% were diagnosed with metabolic syndrome. Significant differences were observed in sex, age, region, marital status, regular worker, and physical activity between participants with and without metabolic syndrome (p < .05). Factors influencing the prevalence of metabolic syndrome included sex, age (with the 19~29 age group showing a significantly lower risk), physical activity, smoking, and perceived stress levels (p < .05). To prevent metabolic syndrome in adult workers, it is essential to promote physical activity, discourage smoking, and encourage effective stress management.\n\nID: 42563498\nTitle: From Gut to Heart: The Emerging Role of Dietary Fermentable Fiber in Heart Failure with Preserved Ejection Fraction.\nAbstract: Heart failure with preserved ejection fraction (HFpEF) is a multisystemic syndrome that accounts for more than half of all heart failure cases and causes a substantial burden of morbidity and mortality. In contrast to heart failure with reduced ejection fraction (HFrEF), few disease-modifying therapies exist for HFpEF, reflecting differences in pathophysiology. Low fermentable fiber (FF) intake, gut dysbiosis, and depletion of short-chain fatty acids (SCFAs), microbial metabolites central to immune, metabolic, and vascular homeostasis, are increasingly linked to the pathophysiology of HFpEF. Here, we synthesize preclinical and clinical evidence on FF and SCFAs and evaluate their therapeutic relevance to HFpEF. Preclinical studies demonstrate that FF supplementation or direct SCFA administration improves cardiometabolic function and attenuates cardiac remodeling through SCFA receptor signaling, enhanced nitric oxide bioavailability, reduced inflammation, and metabolic support of the energy-starved failing heart. Supporting the translational relevance of these findings, a systematic review of 27 human randomized controlled trials showed that FF interventions exert microbiome-mediated effects, enriching SCFA-producing taxa and augmenting fecal and circulating SCFA levels, while improving insulin sensitivity and reducing abdominal adiposity and LDL cholesterol. Direct SCFA supplementation increases SCFA availability and provides modest metabolic benefits, including reduced adiposity and liver fat. However, its effects are inconsistent. Collectively, these findings provide a mechanistic and translational rationale for FF-based interventions in HFpEF. To date, no clinical trials have evaluated the effects of FF on HFpEF-specific outcomes. Clinical studies are therefore needed to determine whether increasing FF intake can improve symptoms, cardiac function, and disease progression in HFpEF.\n\nID: 42563441\nTitle: Phenolic-Rich Lentil Extracts Regulate Cytokine Production, Metabolic Pathways and Barrier Function in Intestinal Epithelial Cells.\nAbstract: Phenolic compounds are recognized for antioxidant, anti-inflammatory, and antidiabetic properties. Lentils are abundant in these compounds, yet comparative studies across varieties and intestinal cells effects remain limited. This study evaluated the nutritional composition, phenolic profile, antioxidant activity, and \u03b1-glucosidase inhibition of four lentil types in raw and cooked forms. L01 had the highest bioactive potential and was the only one selected for further evaluation in Caco-2 cells under basal and IL-1\u03b2-stimulated conditions. Cooking altered composition, leading to higher protein, fiber, and carbohydrates, reducing tannins, and maintaining high phytic acid in some varieties. L01 consistently showed the highest phenolic content, antioxidant activity, and enzyme inhibition. Its phenolic profile was dominated by kaempferol derivatives, (epi)catechin, and procyanidins, with cooking increasing monomeric catechins but reducing procyanidin oligomers. At noncytotoxic levels, L01 extracts reduced IL-6/8 secretion in stimulated cells, with stronger effects from raw extracts. Additionally, they decreased expression of inflammatory markers (IL-6/8/1\u03b2) while increasing expression of metabolic regulation- and barrier-related genes (Peroxisome proliferator-activated receptor-\u03b3, Sirtuin 1, Occludin, and Cadherin-1). Only raw extracts significantly enhanced Heme oxygenase-1 expression under stimulation. These findings highlight compositional differences beyond tegument color and support further investigation of phenolic-rich lentils as potential functional food ingredients targeting gut and metabolic health.\n\nID: 42562480\nTitle: Fermentation of legumes as a strategy to enhance nutritional and sensory properties and modulate gut microbiome and human health.\nAbstract: Legumes represent a valuable and vegetable source of proteins and fiber with a very low environmental footprint production, therefore, both dietary guidelines and international agencies suggest increasing their production and consumption. Despite their favorable nutritional composition, they also naturally contain antinutritional factors such as phytic acid, that limit the absorption of micronutrients. This, coupled with the lower bioavailability of proteins as compared with meat, diminishes the biological and economic value of legumes. However, recent studies have shed a light on the power of fermentation to improve the protein profile of pulse and neutralize antinutritional compounds. In this review, we explore the benefits of legumes fermentation in depth, focusing on the role of microorganisms in enhancing the nutritional and sensory enhancement of legumes. Furthermore, we describe the properties and the microorganisms involved in the production of several craft-based fermented legumes typically consumed by non-Westernized populations, particularly delving into their effects on the gut microbiome and on the human health.\n\nID: 42562455\nTitle: The alleviative effect of protein-polysaccharide complex coacervation microcapsules on loperamide-induced constipation in mice.\nAbstract: The rising incidence of constipation and side effects of clinical drugs have spurred research on natural functional ingredients for its prevention and treatment. Probiotics and dietary fibers have diverse bioactivities but are limited by poor stability and low bioavailability. Herein, a novel microcapsule system co-loading Ganoderma lucidum dietary fiber (GLDF) and Lactobacillus fermentum CECT5716 was constructed using whey protein (WP) and xanthan gum (XG) via hybrid spray drying-complex coacervation. Optimal WP-XG interaction (driven by electrostatic forces and hydrogen bonds) was achieved at pH\u00a03.75 and 5:1 mass ratio; microcapsules with 1:1 wall-to-core ratio showed the best performance, with 72.3% post-encapsulation probiotic viability and enhanced stability under simulated gastrointestinal conditions and storage. Animal experiments confirmed that the microcapsules effectively alleviated loperamide (LOP)-induced constipation in mice, associated with regulating gut microbiota, promoting short-chain fatty acids (SCFAs) production, inhibiting colonic inflammation, repairing intestinal tight junctions, and downregulating aquaporins. In conclusion, the microcapsules prepared in this study provide a feasible strategy for the efficient co-delivery of probiotics and dietary fibers, and the developed composite functional ingredient holds great application potential in the field of constipation prevention and treatment.\n\nID: 42560558\nTitle: Soil biodegradation of virgin and recycled cotton and PET based fabrics: physicochemical and biological assessment.\nAbstract: With increasing waste generation and environmental concerns in textiles, biodegradability is considered one of the most important waste management strategies. The biodegradability behavior of textile products made from virgin materials has been extensively studied. Although it is known that recycled textile products provide significant environmental benefits, whether these materials have created a change in terms of biodegradability is still a subject of interest. Biodegradation of woven fabrics made of virgin cotton (CO)/recycled cotton (r-CO) fibers, recycled polyester (r-PET)/r-CO fiber blends, 100% r-PET fibers and their virgin counterparts, (100% CO and 100% virgin polyester (PET)) fibers were investigated in soil for 1-, 4- and 7- month soil burial periods. Biodegradability properties were determined by weight loss analysis, Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR) analysis and microorganism and organic carbon analyses. According to the results of the study, fabrics made from 100% CO and CO/r-CO fibers exhibited degradation rate of 93-95% after 1\u00a0month and complete degradation after 4\u00a0months. While biodegradation occurred depending on the r-CO ratio in the structure for fabrics produced from r-PET/r-CO fibers, no degradation was observed for 100% PET and 100% r-PET fabrics after 1, 4, and 7\u00a0months. It was concluded that recycled fibers in the structure exhibited similar degradation behavior to their virgin counterparts. Furthermore, SEM and FTIR analyses confirmed the weight loss results. The results of total bacteria, yeast-mold, and organic carbon analyses showed different trends depending on the soil burial periods and biodegradability of the samples.\n\nID: 42560509\nTitle: Adherence to the Mediterranean diet is inversely associated with hematologic inflammatory indices in adults seeking a weight loss dietary program: a cross-sectional study.\nAbstract: Low-grade systemic inflammation is a hallmark of excess adiposity and contributes to cardiometabolic risk. Adherence to the Mediterranean diet has been associated with reduced inflammation. However, evidence linking Mediterranean diet to composite inflammatory indices derived from routine blood tests is limited, particularly in individuals seeking weight loss interventions. In this cross-sectional study, 1,738 adults requesting a weight loss dietary program underwent anthropometric assessment, body composition evaluation, and fasting blood sampling. Adherence to the Mediterranean diet was assessed using the 14-item Mediterranean Diet Adherence Screener (MEDAS). Hematologic inflammatory indices, including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), lymphocyte-to-monocyte ratio (LMR), systemic inflammation response index (SIRI), and monocyte-to-HDL ratio (MHR), were calculated. After adjustments for sex, age, BMI, body fat percentage, metabolic syndrome, smoking status, physical activity, education level, and marital status, each 1-point increase in MEDAS score was associated with lower NLR (\u03b2 = -\u20090.065; 95% CI: -\u20090.102, -\u20090.028, p\u2009=\u20090.001), PLR (\u03b2 = -\u20092.660; 95% CI: -\u20094.570, -\u20090.749, p\u2009=\u20090.006), SII (\u03b2 = -\u200921.233; 95% CI: -\u200931.520, -\u200910.947, p\u2009<\u20090.001), SIRI (\u03b2 = -\u20090.046; 95% CI: -\u20090.068, -\u20090.024, p\u2009<\u20090.001), and MHR (\u03b2 = -\u20090.0002; 95% CI: -\u20090.0003, -\u20090.0001, p\u2009=\u20090.003), and with higher LMR (\u03b2\u2009=\u20090.078; 95% CI: 0.038, 0.117, p\u2009<\u20090.001), all reflecting a shift toward a more favorable inflammatory profile. Greater adherence to the Mediterranean diet was associated with a more favorable inflammatory profile. These results support the role of the Mediterranean diet in modulating low-grade systemic inflammation in clinical nutrition settings.\n\nID: 42560465\nTitle: Therapeutic potential of phytochemical compounds in cardiovascular disease: a comprehensive review.\nAbstract: Cardiovascular diseases (CVDs) continue to be the world's leading cause of death and a major global healthcare burden. Concerns about side effects and long-term therapy restrictions have raised interest in supplementary therapeutic approaches, even if traditional pharmaceutical and surgical procedures are still crucial to the management of CVD. Evidence from published experimental, clinical, and mechanistic investigations that were indexed in PubMed, Scopus, Web of Science, and Google Scholar between 2014 and 2025 is compiled in this review. Through their antioxidant, anti-inflammatory, lipid-lowering, antihypertensive, and endothelial-protective properties, plant-derived phytochemicals such as flavonoids, carotenoids, polyphenols, glucosinolates, and sulfur-containing compounds have considerable cardioprotective potential. Vascular function, oxidative stress, platelet aggregation, insulin sensitivity, and lipid metabolism have all benefited by compounds like quercetin, catechins, curcumin, resveratrol, and lycopene. However, its therapeutic translation is still constrained by issues with bioavailability, dosage uniformity, and clinical validation. Although more extensive clinical research is needed to determine their long-term efficacy and safety, the evidence now available indicates that phytochemicals may be beneficial supplements to traditional cardiovascular treatments.\n\nID: 42559073\nTitle: Clinical and mechanistic evidence on metabolic effects of oat \u03b2-glucan, rice bran, and unripe banana flour: a systematic review with mechanism-informed synthesis.\nAbstract: Dietary fibre improves metabolic health, yet comparative evidence across different fibre sources remains unclear. This systematic review evaluates metabolic effects of oat \u03b2-glucan, rice bran, and unripe banana flour in adults, assessing glycaemic, lipid, and mechanistic effects, synthesising their physiological pathways across distinct fibre types (viscosity-driven, phytochemical-mediated, and resistant starch fermentation mechanisms). Following PRISMA 2020 guidelines, PubMed, Scopus, and Web of Science were searched up to June 2025. A total of 602 records were identified, and after removing 146 duplicates, 456 were screened. Forty-four full texts were assessed, and 15 studies were included. Risk of bias was evaluated using RoB 2.0 and Newcastle-Ottawa. Outcomes included glycaemic markers, insulin response, lipid profile, blood pressure, body composition, and mechanistic biomarkers. Studies (n = 15; sample sizes 10-154; durations 3 days-12 weeks) demonstrated heterogeneous dosing and formulations. Oat \u03b2-glucan consistently improved postprandial glucose, insulin AUC, and LDL-C, with modest effects on waist circumference and blood pressure. Rice bran improved blood lipids consistently, while glycaemic effects were mixed. UBF resistant starch was associated with reduction in fasting glucose, HOMA-IR, and body weight, although findings are based on small, short-duration trials. However, variability in study design and limited mechanistic assessments restricted cross-fibre synthesis. The available evidence suggests modest improvements in glycaemic and lipid outcomes. Differences in responsiveness likely reflect variations in fibre structure, viscosity, and fermentability, suggesting complementary physiological pathways. Standardised dosing, longer interventions, and mechanistic biomarkers - including SCFA profiles, incretin response, and bile acid signalling - are needed to clarify inter-individual variability and guide fibre-based interventions.\n\nID: 42557937\nTitle: Pomegranate Peel Polyphenol Extract Ameliorates Hyperuricemia by Inhibiting Uric Acid Synthesis and Reabsorption.\nAbstract: Hyperuricemia (HUA) is a common metabolic disorder with limited safe and effective therapeutic options. This study integrated GEO dataset mining and network pharmacology to explore the anti-HUA efficacy and mechanism of pomegranate peel polyphenol extract (PPE). In a mouse model of HUA induced by potassium oxonate and 5% fructose water, PPE significantly reduced serum, urinary, and fecal uric acid levels, attenuated the increases in creatinine and blood urea nitrogen, improved estimated glomerular filtration rate, and ameliorated renal pathological damage, inflammation, and xanthine oxidase activity. Integration of GEO-derived HUA-related genes and computational target prediction for PPE identified 44 common targets, and protein-protein interaction network analysis revealed core targets including Akt1. KEGG enrichment highlighted the PI3K-AKT signaling pathway as a key mediator. Western blotting in\u00a0vivo and in\u00a0vitro confirmed that PPE suppressed PI3K-AKT phosphorylation and downregulated the urate reabsorption transporters URAT1 and GLUT9. Furthermore, experiments in UA-induced HK-2 cells demonstrated that ellagic acid, a major bioactive component of PPE, acted through the same pathway. These findings indicate that PPE reduces uric acid levels and protects the kidney via modulation of the PI3K-AKT pathway, providing an integrative data-driven rationale for its potential as a functional food or pharmaceutical agent against HUA.\n\nID: 42557920\nTitle: Natural Agents for Preventing Skin Damage Induced by Visible Light: A Systematic Review of Preclinical and Clinical Evidence.\nAbstract: Visible light (VL), and particularly high-energy visible light (HEVL), reaching Earth's surface has emerged as a relevant contributor to skin damage. VL has been implicated in oxidative stress, inflammation, pigmentation disorders, and photoaging, especially in individuals with darker skin phototypes. As conventional sunscreens offer limited protection in the visible spectrum, increasing attention has been directed toward complementary photoprotective strategies, including the use of natural compounds with antioxidant and anti-inflammatory properties. This systematic review aims to evaluate and synthesize the available preclinical and clinical evidence on the photoprotective effects of natural compounds against VL-induced skin damage, emphasizing their mechanisms of action, efficacy, and safety. A comprehensive literature search was performed to identify studies reporting validated objective outcomes, including colorimetric parameters, diffuse reflectance spectroscopy, or clinical grading scales. Eligible studies were included, qualitatively synthesized, and risk of bias was evaluated. Preclinical studies demonstrated that natural compounds mitigated VL-induced oxidative stress, inflammation, and pigmentation-related pathways. Clinical studies showed that formulations containing natural compounds improved VL-induced erythema and pigmentation outcomes. However, considerable heterogeneity was observed in irradiation protocols, outcome measures, and study designs, precluding quantitative meta-analysis. Overall, available evidence supports a protective role for selected natural compounds against VL-induced skin damage, particularly through antioxidant and anti-inflammatory mechanisms, with the strongest clinical evidence focusing on natural sources of polyphenols. Nevertheless, this review highlights the need for standardized phototesting protocols and well-designed clinical trials. Future research should focus on comparative efficacy, long-term safety, and integration of natural compounds into combined photoprotection strategies tailored to different skin phototypes.\n\nID: 42557588\nTitle: Assessment of cardiometabolic risk using single point insulin sensitivity estimator (SPISE) in pediatric Bardet-Biedl Syndrome: a pilot study.\nAbstract: Bardet-Biedl syndrome (BBS) carries early cardiometabolic risk, yet pediatric screening is complicated by growth and puberty. The metabolic syndrome (MetS) z-score provides a continuous benchmark for clustered risk. The single-point insulin sensitivity estimator (SPISE), based on body mass index (BMI) and fasting lipids, may offer a practical alternative where insulin testing is impractical. We aimed to assess the association between SPISE and cardiometabolic burden in children with molecularly confirmed BBS, and to compare its ability to identify MetS against the MetS z-score benchmark and insulin-derived indices. Single-center retrospective pilot study including children/adolescents with genetically confirmed BBS who underwent standardized anthropometry and metabolic profiling (fasting lipids, glucose, insulin; OGTT when available). SPISE-MetS z-score associations were examined using Spearman and adjusted analyses. In adolescents (\u2265\u200910 years), MetS discrimination was evaluated with ROC curves for SPISE, TG/HDL, and homeostatic model assessment for insulin resistance (HOMA-IR), with pairwise DeLong comparisons and Youden-optimal thresholds. Fourteen participants (7 females, 7 males) were evaluated. Median age at last visit was 11.7 years [IQR 7.6-15.5]; BMI SDS was 3.05 [2.47-3.57]. The median MetS z-score was 1.60 [0.90-1.75]. SPISE correlated inversely with the MetS z-score (\u03c1=-0.57, p\u2009=\u20090.021), and adjusted models (age, sex, BMI-SDS) retained significance. Among adolescents (n\u2009=\u200910), SPISE showed the highest AUC for MetS (AUC 0.95; 95% CI 0.82-1.00) versus TG/HDL (AUC 0.81) and HOMA-IR (AUC 0.60); pairwise differences were not statistically significant. Youden-optimal SPISE\u2009\u2264\u20093.34 identified MetS with high sensitivity in adolescents. Confidence intervals were wide, reflecting the small sample size. In this single-center pediatric BBS cohort, SPISE tracked continuous MetS burden and showed numerically stronger discrimination for MetS than insulin-derived indices. These findings highlight the potential utility of SPISE as a feasible tool for cardiometabolic monitoring in syndromic obesity, where laboratory access may be limited. Beyond BBS, SPISE may support early risk stratification and follow-up in rare obesity models of metabolic risk, but multicenter prospective validation remains warranted.\n\nID: 42556887\nTitle: Microbiota, fermentation, and metabolite biotransformation: Pathways to functional foods and personalised nutrition.\nAbstract: Fermentation is among the oldest biotechnological processes and a modern platform for precision metabolic engineering, enabling the targeted production of health-promoting metabolites. The human gut microbiota, with its complex enzymatic potential, converts dietary substrates into a wide range of bioactive molecules, including short-chain fatty acids, vitamins, neuroactive compounds, and polyphenol-derived metabolites that influence host metabolism, immunity, and neurological functions. Advances in microbial genomics, systems biology, and synthetic biology now allow the design of fermentation processes and engineered microbial strains capable of producing specific metabolites with improved bioavailability and tailored health effects. Precision fermentation integrates traditional microbial fermentation with genome editing, metabolic flux optimisation, and AI-assisted pathway design to achieve predictable yields of vitamins, polyphenols, bioactive peptides, and long-chain polyunsaturated fatty acids. These innovations create opportunities to develop functional foods, nutraceuticals, and personalized nutrition strategies that match metabolite profiles to an individual's microbiome composition. This chapter explores the mechanistic links between microbial metabolism and host health, reviews emerging fermentation technologies for targeted metabolite production, and highlights industrial case studies demonstrating the transition of precision fermentation from research to commercial applications.\n\nID: 42556880\nTitle: Pectins and modified pectins: Bridging food technology and human health innovations.\nAbstract: Pectins are a family of plant polysaccharides with complex structures whose significance extends beyond their established function as food texture modifiers. These compounds are directly relevant to human health, and their impact is influenced by structural diversity. The chemical composition of pectins varies according to botanical origin and is shaped by extraction and modification processes. Such structural differences determine both technological functionality and a range of bioactive properties, establishing pectins as potent dietary fibers with systemic health effects. Modified pectins exhibit immunomodulatory and anticancer activities through mechanisms including receptor interactions and modulation of key signaling pathways. In vivo studies further demonstrate their roles in regulating metabolism and in supporting gut barrier integrity. A critical aspect of pectin bioactivity involves promoting symbiotic interactions within the gut microbiota, increasing microbial diversity, and stimulating the production of beneficial metabolites, including short-chain fatty acids. Translational research, including clinical trials, has confirmed practical benefits for gastrointestinal management and metabolic health, and has highlighted the utility of pectins as adjuvants in pharmaceutical and nutritional formulations. This chapter highlights the link between pectins and the intersection of food science, nutrition, and biomedicine, emphasizing their potential as multifunctional ingredients for innovative health strategies.\n\nID: 42556698\nTitle: Sediment heterogeneity drives divergent arsenic transformation pathways through organic matter-microbial coupling in aquifers.\nAbstract: Arsenic (As) speciation in groundwater is controlled not only by aqueous redox chemistry but also by sedimentary matrices that preserve organic matter, structure metabolism, and regulate Fe-S-As coupling. However, how sedimentary organic matter (SOM) and microbial functional differentiation jointly direct arsenic toward thioarsenate formation and methylation remains insufficiently constrained. This study combined sedimentological characterization, X-ray diffraction mineralogical analysis, Fe/As sequential extraction, excitation-emission matrix fluorescence spectroscopy, FT-ICR-MS molecular characterization of SOM, and metagenomic sequencing across three hydrogeochemical zones. Sediments shifted from coarse-grained alluvial deposits in the low-As recharge zone (ALZ) to fine-grained, organic-rich lacustrine sediments in the thioarsenate-enriched zone (HGD) and the methylation zone (SHX), with clay enrichment in HGD and carbonate enrichment in SHX. Along this gradient, ALZ showed open recharge conditions with labile SOM and dynamic redox environments, whereas As in HGD and SHX shifted from surface-bound forms to poorly crystalline and crystalline Fe-associated fractions, alongside SOM evolution toward humified, aromatic, highly unsaturated, and sulfur-containing molecules. The HGD exhibited enrichment of polyphenols and CHOS/CHONS compounds, providing substrates and redox-active ligands for Fe-S-As coupling. Metagenomics revealed zone-specific functional differentiation. The ALZ was dominated by Proteobacteria supporting heterotrophic metabolism, sulfur oxidation, and arsenic resistance. The HGD showed enhanced sat-aprAB-dsrAB pathways and weakened soxABCDXYZ-mediated sulfur oxidation, favoring reduced sulfur accumulation, Fe-As mineral sulfidation, and thioarsenate formation. The SHX displayed enrichment of arsC and arsenic resistance/efflux genes, supporting As(V) reduction and methylated As transformation. These results demonstrate that sediment heterogeneity governs As speciation and migration through coupled SOM evolution and microbial functional reorganization.\n\nID: 42554875\nTitle: Microbial architects of cigar fermentation: a critical review of beneficial roles in quality enhancement and detrimental potential for mould spoilage.\nAbstract: Cigar tobacco fermentation is a microbially driven process that transforms raw tobacco leaves into a product with distinctive sensory attributes, yet the current understanding of the microbial roles in this process remains fragmented between descriptive community surveys and isolated mechanistic studies, with beneficial and detrimental microbial functions rarely integrated into a unified risk-benefit assessment. This review critically examines the microbiology of cigar fermentation through a dual-axis framework organized around beneficial metabolic functions and detrimental spoilage potential, each resolved into microbial identity, biochemical mechanism, and environmental modulation dimensions. We synthesize evidence from culture-dependent and culture-independent studies on microbial community assembly and succession, where Bacillus, Staphylococcus, and Aspergillus emerge as core fermentation genera, and evaluate the complementary three-pathway system - macromolecular enzymatic degradation, targeted biotransformation of tobacco alkaloids and polyphenols, and de novo biosynthesis of aroma-active volatiles - that drives flavor and quality enhancement. We further analyze the contrastive microbial balance governing tobacco-specific nitrosamine (TSNA) formation, where nitrate-reducing bacteria compete with nitrate-assimilating and nitrite-scavenging microorganisms to determine the net TSNA load. In parallel, we critically examine the mould spoilage microbiology of cigar fermentation, identifying the environmental thresholds - humidity above 80% RH, water activity above 0.85, and inadequate aeration - that select for mycotoxigenic Aspergillus and Penicillium species producing aflatoxins and ochratoxin A at levels that persist into the finished product. We survey emerging biotechnological strategies spanning bioaugmentation with defined starter cultures, biostimulation through environmental optimization, and biocontrol of spoilage fungi, and identify five critical research gaps - including the absence of gnotobiotic fermentation models and the predominance of correlative over causal studies - that must be addressed to translate microbial ecology into predictable fermentation biotechnology. By integrating microbial ecology, fermentation biochemistry, spoilage prevention, and applied biotechnology, this review is intended for researchers in tobacco microbiology and fermentation science, as well as cigar manufacturers, quality-control practitioners, and biotechnologists seeking microbiome-based strategies for quality improvement and risk mitigation.\n\nID: 42554133\nTitle: Harnessing of Tomato (Solanum lycopersicum) Pomace Powder on Growth Response and Haematological Indices of Sonali Chickens.\nAbstract: Tomato pomace, a processing by-product rich in lycopene and polyphenols, has not yet been systematically evaluated as a functional dietary supplement for Sonali chickens in Bangladesh. This study assessed the dose-dependent effects of dried tomato pomace powder (TPP) as a dietary additive on the growth performance, feed efficiency, carcass traits, haematological indices and economic returns of Sonali chickens under tropical conditions in Bangladesh. A total of 180, one day-old Sonali chicks were randomly allocated to four dietary treatments, T0 (basal diet), T1 (basal diet\u00a0+\u00a02% TPP), T2 (basal diet\u00a0+\u00a04% TPP) and T3 (basal diet\u00a0+\u00a06% TPP), with three replicates of 15 birds each, and reared for 63 days at the Central Poultry Farm, HSTU, Dinajpur, Bangladesh. The T3 group achieved the highest final live body weight, the greatest weight gain and the most efficient feed conversion, followed by T2, T1 and T0 (p\u00a0<\u00a00.05). Carcass weight and breast, thigh and drumstick yields were significantly higher in T3. Blood analysis showed significantly lower total cholesterol and LDL together with higher HDL in the T3 group. The economic analysis indicated that T3 generated the highest net profit per bird, differing significantly from T0 (p\u00a0<\u00a00.05). Supplementing the diet with dried TPP at 6% significantly improved growth performance, carcass quality, lipid metabolism and financial returns in Sonali chickens, indicating that it is a viable, low-cost functional feed supplement for tropical poultry production systems.\n\nID: 42554025\nTitle: High Methoxyl Pectin Consistently Reduces \u03b2-Carotene Bioaccessibility Across Various Gastrointestinal Digestion Conditions.\nAbstract: Dietary fiber could inhibit \u03b2-carotene bioaccessibility by restricting its release from the food matrix, interfering with digestive enzyme activities, binding bile salts, or modifying viscosity and other physicochemical properties of the digesta. In this study, we investigated whether high methoxyl pectin (HMP), a soluble dietary fiber found in fruits/vegetables and an additive for the food industry would impact \u03b2-carotene bioaccessibility under various physiological digestive conditions, following the INFOGEST gastrointestinal model. Concentrations of pancreatin plus bile salts and shear forces (simulated by varying water bath rounds/min. and glass bead addition) were modified in the presence (1.15\u00a0mg/mL digesta) and absence of HMP. Endpoints measured in the digesta included \u03b2-carotene bioaccessibility, surface tension, viscosity, micelle size, zeta potential, and triglyceride lipolysis. Adding HMP reduced overall bioaccessibility of \u03b2-carotene from 32.1\u00b16.2% to 24.1\u00b15.7% (p<0.001). All other parameters also had a significant impact on the bioaccessibility of \u03b2-carotene, that is, bile/pancreatin concentration (p<0.001), water bath shaking speed (p<0.001), and glass beads (p\u00a0=\u00a00.001). Surface tension, viscosity, and micelle size were less strongly affected by HMP addition (p<0.05), though not triglyceride lipolysis. The inhibitory effect of HMP varied depending on bile/pancreatin concentration and shear-forces, with strongest reductions when \u03b2-carotene bioaccessibility was highest at onset.\n\nID: 42552917\nTitle: Short-chain fatty acid-producing psychobiotics in mood disorders: mechanistic insights into the microbiota-gut-brain axis.\nAbstract: Mood disorders, including major depressive disorder, bipolar disorder, generalized anxiety disorder, and posttraumatic stress disorder, constitute a primary source of global disability, and with conventional monoamine-targeted pharmacotherapy, approximately one-third of patients remain with treatment-resistant disease. Over the past decade, the microbiota-gut-brain axis (MGBA) has emerged as a systems-level pathophysiological framework that explains the chronic neuroinflammation, hypothalamic-pituitary-adrenal axis hyperactivity, and impaired neuroplasticity that characterize treatment-resistant mood disorders. Short-chain fatty acids (SCFAs) are key molecular mediators in MGBA signaling, exerting epigenetic regulation through the inhibition of histone deacetylase, suppression of microglial toll-like receptor 4/nuclear factor-kappa B signaling, reinforcement of intestinal and blood-brain barrier integrity, and rebalancing of tryptophan-kynurenine metabolism. A few small randomized controlled trials and meta-analyses have reported that restoring SCFA output using next-generation psychobiotics (Faecalibacterium prausnitzii, Akkermansia muciniphila, and Clostridium butyricum), prebiotic-rich dietary patterns, defined synbiotics, and direct postbiotic supplementation is associated with symptom improvement, although the evidence base remains preliminary, and have been proposed as candidate prognostic biomarkers. This narrative review synthesizes 2022 to 2026 mechanistic and clinical evidence on SCFA-producing psychobiotics in mood disorders; integrates these findings within a clinical nutrition framework that positions dietary fiber, microbiota-accessible carbohydrates, and targeted psychobiotic supplementation as legitimate adjuncts to conventional psychopharmacology; and discusses the translational challenges of strain specificity, dosing variability, and precision-psychobiotic medicine. Nevertheless, current evidence remains dominated by preclinical models, with human trials constrained by size, duration, and number.\n\nID: 42552471\nTitle: Accurate Measurement of Serum Free Testosterone Levels via Liquid Chromatography\u2012Tandem Mass Spectrometry (LC\u2012MS/MS) has Predictive Value in the Diagnosis of Polycystic Ovary Syndrome and Associated Metabolic Disorders.\nAbstract: Polycystic ovary syndrome (PCOS), in which hyperandrogenism is a major feature, is the most prevalent endocrine disorder among women of reproductive age. Serum free testosterone (FT) reflects the biologically active fraction of circulating testosterone. Accurate assessment of FT allows for precise identification of hyperandrogenism and provides critical guidance for the diagnosis of PCOS. Women with PCOS and normal controls (NCs) were included in this study. Fasting serum samples were collected during the early follicular phase to evaluate key clinical parameters, and FT levels were quantified using liquid chromatography\u2012tandem mass spectrometry (LC\u2012MS/MS). The diagnostic value of FT for identifying PCOS was assessed using Spearman's correlation analysis and receiver operating characteristic curves. A total of 202 women were included in the PCOS group, 121 were included in the NC group. Total testosterone (TT), free androgen index (FAI), and FT levels were significantly greater in the PCOS group than in the NC group. Both FAI and FT were positively correlated with body mass index (BMI), triglycerides, low-density lipoprotein cholesterol, fasting insulin and the homeostasis model assessment for insulin resistance; and were negatively correlated with high-density lipoprotein cholesterol. Following age and BMI adjustments, the area under the curve (AUC) for FT (AUC\u2009=\u20090.886) was greater than that for TT (AUC\u2009=\u20090.856) or FAI (AUC\u2009=\u20090.864). Compared with conventional assessments of TT and FAI, LC-MS/MS-based measurements of FT demonstrate superior diagnostic performance for identifying PCOS. Both FT and FAI are associated with obesity and the features of metabolic syndrome in PCOS patients.\n\nID: 42550282\nTitle: Ultrasensitive electrochemiluminescence determination of Salmonella based on CRISPR/Cas12a integrated with bimetallic semiconductive metal-organic frameworks.\nAbstract: An ultrasensitive electrochemiluminescence (ECL) biosensor was established by combining CRISPR/Cas12a technique and semiconductive bimetallic-organic framework (scMOF) [[CuxNi3-x(HITP)2] (HITP\u2009=\u20092,3,6,7,10,11-hexaiminotriphenylene)]] emitter and employed to detect Salmonella using the allosteric probe as the recognition component. Given that CuxNi3-x(HITP)2 has demonstrated large specific surface area, both in-plane and out-of-plane charge transfer ability, narrowed band gap, and enhanced separation of holes and electrons, it can be simultaneously employed as the superior ECL emitter and bioplatform for anchoring single-strand DNA (ssDNA), thus improving the detection sensitivity toward Salmonella. The CRISPR/Cas12a-based system can specifically recognize the target sequence of Salmonella and activate the nuclease activity of Cas12a, and the activated Cas12a possesses trans-cleavage ability toward ssDNA. The CuxNi3-x(HITP)2 emitter is then released, resulting in the decline of the ECL response. The developed CuxNi3-x(HITP)2-CRISPR/Cas12a-based ECL biosensor exhibits the ultralow detection limit of 0.25 CFU mL-\u20091 in the linear range from 1.0 CFU mL-\u20091 to 106 CFU mL-\u20091, significantly lower than those of reported ones. Furthermore, the developed biosensor exhibits outstanding overall biosensing properties with high selectivity, favorable reproducibility and stability, together with promising practical applicability for the determination of Salmonella in a variety of foodstuffs.\n\nID: 42550246\nTitle: Protective effects of Rhus coriaria L. fruit extract against experimental calcium oxalate nephrolithiasis via modulation of oxidative stress and renal injury.\nAbstract: Calcium oxalate nephrolithiasis is strongly associated with oxidative stress, renal tubular injury, and inflammation. Natural products rich in polyphenols may serve as promising complementary preventive strategies. This study investigated the antiurolithiatic and renoprotective effects of Rhus coriaria fruit extract in an ethylene glycol-induced rat model of nephrolithiasis. Forty-two male rats were randomized into seven groups (n\u2009=\u20096): control, ethylene glycol (EG), EG\u2009+\u2009potassium citrate, R. coriaria 250\u00a0mg/kg/day, R. coriaria 500\u00a0mg/kg/day, EG\u2009+\u2009R. coriaria 250\u00a0mg/kg/day, and EG\u2009+\u2009R. coriaria 500\u00a0mg/kg/day. Nephrolithiasis was induced with 1% ethylene glycol for 28 days. Serum biochemistry, urinary lithogenic parameters, oxidative stress markers including total antioxidant status (TAS), total oxidant status (TOS), superoxide dismutase (SOD), catalase (CAT), and malondialdehyde (MDA), histopathology, and immunohistochemical expression of kidney injury molecule-1 (KIM-1) and osteopontin (OPN) were evaluated. Phytochemical characterization of the extract was performed by high-performance liquid chromatography coupled with diode-array detection (HPLC-DAD). Gallic acid was identified as the predominant phenolic constituent, together with smaller amounts of protocatechuic acid and ellagic acid. Ethylene glycol significantly increased urinary lithogenic parameters, oxidative stress indices, crystal deposition, tubular injury, and OPN expression. Treatment with R. coriaria significantly reduced urinary oxalate and calcium levels, improved TAS, SOD, and CAT levels, lowered TOS and MDA concentrations, and markedly attenuated crystal deposition, inflammation, and tubular dilatation. OPN expression was substantially decreased in treated groups, whereas KIM-1 showed a decreasing trend. Protective effects were more pronounced at the 500\u00a0mg/kg/day dose. R. coriaria fruit extract exerted significant antiurolithiatic and renoprotective effects in experimental calcium oxalate nephrolithiasis. These findings suggest that R. coriaria may represent a potential adjunctive strategy for calcium oxalate stone disease.\n\nID: 42549898\nTitle: The relationship between neck circumference and cardiometabolic risk factors in children and adolescents with obesity.\nAbstract: the aim of our study was to evaluate the association between neck circumference (NC) and cardiometabolic risk factors in children and adolescents with obesity. a cross-sectional study was conducted from October to December 2024, involving 364 children and adolescents with obesity (aged 5 to 17.9 years). Participants were categorized as metabolic syndrome (MetS) or non-MetS according to the International Diabetes Federation criteria. Subjects were further divided into pre-pubertal, mid-pubertal, and post-pubertal groups. the cohort comprised 188 females and 176 males, with a median age of 12.7 years and a median BMI of 29.37 kg/m\u00b2. MetS was diagnosed in 111 participants (30.5 %), with a prevalence of 19.8 % in pre-pubertal, 34.8 % in mid-pubertal, and 38.1 % in post-pubertal individuals. Participants with MetS had higher NC and NC z-scores, BMI, waist circumference (WC), hip circumference (HC), waist-to-height ratio (WHtR), and systolic and diastolic blood pressure. They also had higher fasting triglycerides, uric acid, fasting plasma glucose, insulin levels, and HOMA-IR. NC demonstrated significant correlations with age, BMI, WC, HC, and metabolic parameters. In multivariate logistic regression analysis, NC emerged as an independent predictor of MetS. Threshold NC values indicative of MetS were identified as 32.75 cm (pre-pubertal), 35.50 cm (mid-pubertal), and 36.25 cm (post-pubertal). this study shows that NC is markedly increased in children and adolescents with MetS and independently predicts MetS. Moreover, our findings indicate that associations between NC and cardiometabolic risk factors, supporting NC as a practical marker for cardiometabolic risk stratification in pediatric obesity.\n\nID: 42549200\nTitle: Differential shaping of equine gut microbiota structure and function by breed and feeding regimen.\nAbstract: The gut microbiota plays an essential role in host energy metabolism and immune function. Horses are non-ruminant herbivores that rely heavily on hindgut microbial fermentation to meet their energy requirements. However, the relative contributions of host genetic background (breed) and environmental factors (feeding regimen and geographical location) to shaping the equine gut microbiota remain poorly understood. In this study, 16S rRNA gene sequencing and functional prediction analysis were performed on 139 equine fecal samples to systematically investigate the differential effects of breed and feeding regimen on the gut microbiota. Samples were collected from 30 Thoroughbreds (TH), 31 stabled hybrid horses (HH1), 30 grazing hybrid horses (HH2) (with HH1 and HH2 sired by Thoroughbreds out of Mongolian mares), 32 Mongolian horses (MH), and 16 Warmblood horses (WBH1 and WBH2). Alpha and beta diversity analyses, taxonomic profiling, and PERMANOVA were used to assess microbial composition and the contributions of different factors. Alpha diversity analysis revealed that the richness and diversity of the TH, HH1, HH2, and MH groups were significantly higher than those of the Warmblood horses (p\u202f<\u202f0.001), with Mongolian horses exhibiting the highest diversity and the hybrids showing intermediate levels between their parental breeds. Regarding taxonomic composition, the TH, HH1, HH2, and MH groups shared a microbial structure dominated by Firmicutes and Bacteroidota, yet each possessed distinct characteristics: Thoroughbreds were enriched with Treponema; Mongolian horses harbored the highest abundances of Rikenellaceae_RC9_gut_group and NK4A214_group; and the grazing hybrid horses developed a fiber-degrading bacterial community centered on Ruminococcus and Fibrobacter, demonstrating breed-specific microbial features. In contrast, the Warmblood horses exhibited a gut microbiota with distinct features characterized by significantly reduced microbial diversity and core fiber-degrading genera, concomitant with an enrichment of environmental-associated bacteria from the phylum Proteobacteria (e.g., Acinetobacter, Stenotrophomonas) and other genera (e.g., Comamonas, Brevundimonas). PERMANOVA analysis further quantified the contributions of different factors: breed explained 44.8% of the total variation (R\u00b2 = 0.448, p < 0.001), followed by feeding regimen (10.3%, p < 0.001) and geographical location (2.7%, *p* < 0.01), confirming breed as the predominant factor. This study provides evidence that breed establishes the foundational framework of the gut microbiota, while feeding regimen performs fine-tuning functions. We also systematically characterized the unique microbial composition of Warmblood horses, offering a scientific basis for breed-specific health management, precision nutritional interventions, and future disease risk monitoring in horses. Although all horses appeared clinically healthy, the distinct microbial composition observed in Warmblood horses warrants further investigation to determine its biological significance.\n\nID: 42547443\nTitle: [Research progress on the role of calcitonin gene-related peptide in the repair of diabetic wounds].\nAbstract: Diabetic wounds are a severe complication of diabetes, which can lead to amputation or even mortality in severe cases. While normal wound healing consists of four phases: hemostasis, inflammation, proliferation, and remodeling, diabetic wounds tend to become chronic and refractory primarily due to a prolonged inflammatory phase. In diabetic wounds, insufficient synthesis and release of endogenous calcitonin gene-related peptide (CGRP) is a critical upstream mechanism underlying the disrupted neuro-immune communication, the persistent inflammation, and the arrested wound healing process. In contrast to pure skin defect wounds, where CGRP is rapidly upregulated after injury, CGRP remains persistently low in diabetic wound tissue, consequently failing to drive macrophage polarization towards the M2 phenotype or promote vascular maturation and collagen fiber deposition in the later phase of inflammation. In the early inflammatory phase, CGRP exerts pro-inflammatory effects by enhancing angiogenesis and modulating macrophage polarization. In the late inflammatory phase, CGRP upregulates thrombospondin-1, promotes neutrophil apoptosis and phagocytic clearance, thereby inhibiting excessive inflammatory response and shifting the wound microenvironment from a pro-inflammatory state to a pro-reparative state. Restoring CGRP signaling reconstructs the neuroimmunomodulation axis and improves wound repair while relieving diabetic neuropathic pain. Engineered CGRP combined with intelligent delivery systems offers promising prospects for diabetic wound therapy. However, large-scale clinical trials are still required to validate its clinical efficacy and safety. This paper systematically analyzes the mechanisms and application strategies of CGRP in facilitating diabetic wound repair, which can provide a theoretical basis and innovative strategies for clinical management. \u7cd6\u5c3f\u75c5\u521b\u9762\u662f\u4e00\u79cd\u7cd6\u5c3f\u75c5\u5e76\u53d1\u75c7\uff0c\u4e25\u91cd\u8005\u53ef\u81f4\u60a3\u8005\u622a\u80a2\u751a\u81f3\u6b7b\u4ea1\u3002\u6b63\u5e38\u7684\u521b\u9762\u6108\u5408\u5386\u7ecf\u6b62\u8840\u3001\u708e\u75c7\u3001\u589e\u6b96\u3001\u91cd\u58514\u4e2a\u9636\u6bb5\uff0c\u7cd6\u5c3f\u75c5\u521b\u9762\u4e3b\u8981\u56e0\u708e\u75c7\u671f\u5ef6\u957f\u800c\u6162\u6027\u96be\u6108\u3002\u7cd6\u5c3f\u75c5\u521b\u9762\u7ec4\u7ec7\u4e2d\u964d\u9499\u7d20\u57fa\u56e0\u76f8\u5173\u80bd\uff08CGRP\uff09\u5408\u6210\u4e0e\u91ca\u653e\u4e0d\u8db3\uff0c\u8fd9\u662f\u5bfc\u81f4\u521b\u9762\u795e\u7ecf\u514d\u75ab\u901a\u8baf\u4e2d\u65ad\u3001\u708e\u75c7\u65e0\u6cd5\u6d88\u9000\u3001\u6108\u5408\u8fdb\u7a0b\u505c\u6ede\u7684\u5173\u952e\u4e0a\u6e38\u673a\u5236\u3002\u4e0e\u5355\u7eaf\u76ae\u80a4\u7f3a\u635f\u521b\u9762\u4e2dCGRP\u5728\u4f24\u540e\u8fc5\u901f\u4e0a\u8c03\u4e0d\u540c\uff0c\u7cd6\u5c3f\u75c5\u521b\u9762\u7ec4\u7ec7\u4e2dCGRP\u5448\u6301\u7eed\u6027\u4f4e\u6c34\u5e73\u8868\u8fbe\uff0c\u65e0\u6cd5\u5728\u708e\u75c7\u540e\u671f\u9a71\u52a8\u5de8\u566c\u7ec6\u80de\u5411M2\u578b\u6781\u5316\uff0c\u4fc3\u8fdb\u8840\u7ba1\u6210\u719f\u4e0e\u80f6\u539f\u7ea4\u7ef4\u6c89\u79ef\u3002\u5728\u708e\u75c7\u521d\u671f\uff0cCGRP\u901a\u8fc7\u4fc3\u8fdb\u65b0\u8840\u7ba1\u751f\u6210\u3001\u8c03\u8282\u5de8\u566c\u7ec6\u80de\u6781\u5316\u7b49\u53d1\u6325\u4fc3\u708e\u4f5c\u7528\uff1b\u800c\u5728\u708e\u75c7\u540e\u671f\uff0cCGRP\u901a\u8fc7\u4e0a\u8c03\u8840\u5c0f\u677f\u53cd\u5e94\u86cb\u767d-1\uff0c\u4fc3\u8fdb\u4e2d\u6027\u7c92\u7ec6\u80de\u51cb\u4ea1\u4e0e\u80de\u846c\u6e05\u9664\uff0c\u8fdb\u800c\u6291\u5236\u8fc7\u5ea6\u708e\u75c7\u53cd\u5e94\uff0c\u63a8\u52a8\u521b\u9762\u5fae\u73af\u5883\u7531\u4fc3\u708e\u72b6\u6001\u5411\u4fc3\u4fee\u590d\u72b6\u6001\u8f6c\u53d8\u3002\u6062\u590dCGRP\u4fe1\u53f7\u53ef\u91cd\u5851\u795e\u7ecf\u514d\u75ab\u8c03\u63a7\u8f74\uff0c\u517c\u5177\u4fc3\u8fdb\u521b\u9762\u4fee\u590d\u4e0e\u7f13\u89e3\u7cd6\u5c3f\u75c5\u795e\u7ecf\u75c5\u7406\u6027\u75bc\u75db\u7684\u53cc\u91cd\u4f5c\u7528\u3002\u5de5\u7a0b\u5316CGRP\u4e0e\u667a\u80fd\u9012\u9001\u7cfb\u7edf\u4e3a\u7cd6\u5c3f\u75c5\u521b\u9762\u6cbb\u7597\u5e26\u6765\u65b0\u5e0c\u671b\uff0c\u4f46\u5176\u5728\u4e34\u5e8a\u5e94\u7528\u4e2d\u7684\u6709\u6548\u6027\u4e0e\u5b89\u5168\u6027\u4ecd\u9700\u5927\u89c4\u6a21\u7814\u7a76\u9a8c\u8bc1\u3002\u8be5\u6587\u6df1\u5165\u5256\u6790CGRP\u5728\u7cd6\u5c3f\u75c5\u521b\u9762\u4fee\u590d\u4e2d\u7684\u4f5c\u7528\u673a\u5236\u53ca\u5e94\u7528\u7b56\u7565\uff0c\u4e3a\u4e34\u5e8a\u6cbb\u7597\u63d0\u4f9b\u7406\u8bba\u4f9d\u636e\u4e0e\u65b0\u601d\u8def\u3002.\n\nID: 42547437\nTitle: [Effects and mechanisms of PIT on wound healing of full-thickness skin defects in diabetic mice].\nAbstract: Objective: To investigate the effects and mechanisms of polyvinyl alcohol/ionic liquid-tannic acid composite hydrogel (PIT) on wound healing of full-thickness skin defects in diabetic mice. Methods: This study was an experimental research involving grouped design and repeated measurements. An ionic hydrogel matrix crosslinked by polyvinyl alcohol-4-(1H)-vinylimidazole-1-methylene benzoic acid and oxidized hyaluronic acid was prepared, and tannic acid was loaded via Cu2+ chelation to construct PIT. A 1,1-diphenyl-2-picrylhydrazyl (DPPH) solution was prepared and reacted respectively with tannic acid and PIT for 24 hours. An ultraviolet spectrophotometer was used to detect the DPPH radical scavenging rate. According to the random number table method (the same grouping method below), mouse macrophage RAW264.7 cells were divided into a phosphate buffered saline (PBS) group cultured with PBS, as well as a hydrogen peroxide group and a PIT group, in which cells were first treated with hydrogen peroxide for 12 hours and then respectively cultured under routine condition and with PIT. After 24 hours of culture, the fluorescent probe method was adopted to detect the intracellular reactive oxygen species (ROS) level. Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 25923, methicillin-resistant Staphylococcus aureus (MRSA) BNCC 337371, and human umbilical vein endothelial cells (HUVECs) were collected and all divided into PBS group, tannic acid (TA) group, and PIT group, which were cultured with PBS, TA solution, and PIT, respectively. After 12 hours of bacterial culture, the plate counting method was used to count bacterial colonies; after 24 hours of cell culture, the tube formation assay was performed to measure the total tube length, the number of branching nodes, and the number of branches. The sample size of all the above experiments was 3. Eighteen 8-week-old male Kunming mice were selected and divided into PBS group, TA group, and PIT group (with 6 mice in each group) to establish a full-thickness skin defect wound model of diabetes (with one wound in each mouse). At post injury day (PID) 0 (immediately), the wounds of mice in PBS group, TA group, and PIT group were treated respectively with PBS, TA solution, and PIT by topical application, and then the dressings were changed daily. The wound healing status was observed at PID 0, 4, 8, and 12, and the wound healing rates at PID 4, 8, and 12 were calculated. At PID 12, wound tissue was harvested. Hematoxylin-eosin staining was performed to observe the status of wound re-epithelialization and to measure the thickness of newly formed epithelium. Masson staining was performed to observe the deposition of collagen fibers in wounds and to calculate the proportion of collagen fiber-positive area. Results: After 24 hours of reaction, the DPPH radical scavenging rate of PIT was significantly higher than that of TA (t=16.35, P<0.05). After 24 hours of culture, the ROS level of RAW264.7 cells in hydrogen peroxide group was significantly higher than that in PBS group (P<0.05), and the ROS level of RAW264.7 cells in PIT group was significantly lower than that in hydrogen peroxide group (P<0.05). After 12 hours of culture, the bacterial colony counts of Escherichia coli, Staphylococcus aureus, and MRSA in PIT group were significantly less than those in PBS group and TA group (P<0.05). After 24 hours of culture, compared with those in PBS group and TA group, the total tube length of HUVECs in PIT group was significantly increased (with P values both <0.05), and the number of branching nodes and the number of branches increased significantly (with P values all <0.05). From PID 0 to 12, the wounds of mice in all three groups healed gradually. At PID 4, 8, and 12, the wound healing rates of mice in PIT group were (31.6\u00b12.0)%, (51.8\u00b12.5)%, and (97.9\u00b11.5)%, respectively, which were significantly higher than (18.6\u00b10.6)%, (39.5\u00b12.0)%, and (74.6\u00b12.0)% in PBS group and (21.5\u00b11.1)%, (40.7\u00b10.8)%, and (85.3\u00b12.1)% in TA group (P<0.05). At PID 12, the wound re-epithelialization of mice in PBS group was incomplete, and collagen fibers were sparsely distributed with disordered arrangement; the degree of wound re-epithelialization of mice in TA group was higher than that in PBS group, and collagen fibers were distributed in bundles with loose arrangement; the degree of wound re-epithelialization of mice in PIT group was higher than that in TA group, and collagen fibers were densely and orderly arranged in layers. At PID 12, compared with those in PBS group and TA group, the thickness of newly formed epithelium in wounds of mice in PIT group was significantly increased (with P values both <0.05), and the proportion of collagen fiber-positive area was significantly increased (with P values both <0.05). Conclusions: PIT significantly accelerates the wound healing of full-thickness skin defects in diabetic mice through multiple mechanisms driven by metal ion chelation including antibacterial, antioxidant, and pro-angiogenesis activities, thereby improving the quality of tissue repair. \u76ee\u7684\uff1a

widely recognized for its favorable nutritional properties, while the molecular mechanisms underlying differences in meat quality between New Zealand White rabbits and Rex rabbits are essential for rabbit production. In this study, a total of 120 healthy 13-week-old rabbits (60 per group) were used to evaluate meat quality traits. The longissimus dorsi muscle (LDM) was then collected for transcriptomic and metabolomic analyses. The results showed that New Zealand White rabbits exhibited significantly higher live weight before slaughter, eviscerated weight, semi-eviscerated weight, and pH24 (p\u2009<\u20090.01), whereas Rex rabbits displayed higher cooking loss (p\u2009<\u20090.01) and intramuscular fat content (p\u2009<\u20090.05). Metabolomic profiling identified 218 differential metabolites (DMs), which were mainly enriched in amino acid biosynthesis and the pentose phosphate pathway, including key metabolites such as DL-arginine, gallic acid, and lipid-related compounds. Transcriptomic analysis identified 227 differentially expressed genes (DEGs) enriched in pathways associated with muscle development and meat quality, including oxidative phosphorylation, FoxO, and MAPK signaling pathways. Key DEGs, such as MYH13, HOXA13, and PDK4, were associated with muscle fiber formation and fat deposition. Integrated analysis revealed that 34 DEGs and 24 DMs were co-enriched in 26 pathways, with strong correlations observed between oxidative phosphorylation-related genes and energy metabolites, as well as between collagen-associated genes and amino acids. These findings establish a gene-metabolite regulatory network underlying breed-specific differences in meat quality and identify potential molecular markers to improve rabbit meat quality and to better understand muscle metabolism across different rabbit breeds.\n\nID: 42545432\nTitle: Hypertrophic cardiomyopathy-linked Tnnc1 variants are associated with distinct myopathic changes in slow skeletal muscle of mice.\nAbstract: Inherited hypertrophic cardiomyopathy (HCM) is considered a disease of the cardiac sarcomere and caused by pathogenic variants present in genes that encode sarcomeric proteins. The human TNNC1 gene is a designated HCM-susceptibility gene encoding the troponin C (TnC) protein, which is expressed in both cardiac and type I slow skeletal muscles and abbreviated as cTnC and ssTnC respectively. HCM patients have been reported to exhibit skeletal muscle weakness and reduced exercise tolerance. Patients bearing TNNC1 cardiac pathogenic variants also express it in type I fibers of their slow skeletal muscles. We hypothesized that the presence of TNNC1 HCM variants in type I fibers may decrease force generating capabilities and alter fatigue resistance of slow skeletal muscles. To address this, we examined the impact of HCM Tnnc1 variants in the soleus muscles of two HCM knock-in mouse models A8V+/-, A8V-/-, and C84Y+/- and their respective wild type (WT) controls. At high stimulation frequencies, we found that A8V-/- soleus muscles had lower tetanic force production than WT, however no differences in fatigue when comparing fatigue indices for either of the variants. The muscles were evaluated by comparing % specific force (N/cm2)-variant and both A8V-/- and C84+/- had increased responsiveness at low stimulation frequencies. Fiber type analysis uncovered an increase in abundance of type I fibers in A8V-/- soleus, however no other differences were observed in fiber-type percentage of either mouse model. Comparison of the cross-sectional areas (CSA) of type I fibers in soleus muscles revealed lower average values for A8V+/+ and A8V-/-, however an increase in C84Y+/- relative to controls. Examination of the CSA of type IIa fibers uncovered decreased values for both A8V+/- and A8V-/- with no changes in C84Y+/- soleus. Histological evaluation of A8V+/- and A8V-/- soleus muscles revealed central nucleation and the detection of embryonic myosin heavy chain by immunofluorescence suggested the presence of mild regeneration. In contrast, no histopathological changes were detected in the C84Y+/- soleus muscle. Serum myokines were also measured to assess systemic impacts of the pathogenic variants and alterations in the physical activity of the mice but no significant changes were found. Taken together our results suggest that the HCM A8V variant alters force production in soleus muscle that may be attributed to fiber atrophy and heightened pathophysiology.\n\nID: 42545099\nTitle: Transcriptomic Association of COL3A1+ Fibroblasts With Mechanical Pain-Related Gene Signatures in Triple-Negative Breast Cancer.\nAbstract: Epidemiological data show that approximately 80% of cancer patients experience pain of varying degrees throughout the course of their disease, with nearly one-third experiencing severe pain, significantly impacting their quality of life and the effectiveness of antitumor treatment. Triple-negative (TN) breast cancer tissues typically exhibit increased stromal stiffness and abnormally elevated mechanical stress; these biomechanical alterations may amplify pain signals by activating mechanosensitive channels. Utilizing single-cell RNA sequencing analysis, this study aims to elucidate the potential biological links between fibroblast mechanotransduction and cancer-associated pain, thereby providing a theoretical basis for clinical diagnosis and treatment. Dimensionality reduction and unsupervised clustering were used to identify cell types in TN breast cancer single-cell RNA sequencing data. To assess the association between pain and mechanical stimulation, we constructed a set of gene signatures associated with mechanical stimulation and pain and calculated scores using the Area Under the Curve Cell (AUCell). CellChat and SCENIC were used to reveal the communication networks and transcription factor regulatory mechanisms of fibroblast subtypes. COL3A1+ fibroblasts derived from TN breast cancer are highly involved in biological processes such as extracellular matrix remodeling, collagen fiber formation, and mechanotransduction. To assess the association between pain and mechanical stimulation, we constructed a gene signature set related to mechanical stimuli and pain and calculated corresponding scores using the AUCell tool. Cell communication studies showed that COL3A1+ fibroblasts interact extensively with epithelial cells and other cells through laminin and collagen signaling pathways, potentially leading to mechanotransduction remodeling of the TN breast cancer microenvironment. COL3A1+ fibroblasts demonstrate enhanced transcriptional profiles pertinent to collagen deposition and cytoskeletal reorganization, which are correlated with mechanotransduction signaling and may be connected with mechanical sensitivity in cancer-related pain. This study systematically characterizes the potential relationship between fibroblast-associated mechanotransduction characteristics and pain-related gene signatures at the single-cell level in TN breast cancer. These findings offer hypothesis-generating insights into the molecular landscape of tumor-associated pain, although additional experimental and clinical validation is necessary.\n\nID: 42544286\nTitle: Can increasing footwear bending stiffness ameliorate age-related mechanical and metabolic deficits in walking?\nAbstract: Older adults consume metabolic energy faster than their younger adult counterparts while walking, particularly on sloped terrain. This increased rate is likely in part due to an age-related shift in moment and power production from the ankle joint to the hip. Shifting these mechanics proximally may occur due to older adults losing more mechanical energy at the foot and producing lower ankle joint moments, deficits that are exaggerated when walking uphill or against impeding forces. A promising method to target some of these foot and ankle mechanics differences is increasing footwear longitudinal bending stiffness via carbon fiber insoles. We examined how increasing footwear stiffness alters older adult (9F/10M, 70\u00a0\u00b1\u00a05.9 yrs) walking energetics across slopes. Increasing footwear stiffness reduced the magnitude of negative power from the foot+shoe structures distal to the forefoot, but increased negative power of the foot+shoe structures distal to the hindfoot (foot+shoe complex as a whole). At the ankle, peak joint moment increased by \u223c10% in the stiffest footwear compared with the baseline standardized shoe. Neither knee and hip mechanics nor net metabolic power were consistently affected by footwear stiffness. These results indicate that increasing older adult footwear stiffness via flat carbon fiber insoles attenuates some age-related deficits in foot and ankle mechanics, but does not result in a clear attenuation of the age-related distal to proximal shift in joint mechanics or clear metabolic benefits. The increase in ankle joint moment with stiffer footwear could be useful longer-term as a means to strengthen the calf musculature of older adults. Future work should examine the effects of footwear stiffening on ankle muscle-level outcomes such as force production, excitation, and fascicle mechanics.\n\nID: 42543925\nTitle: Hypothyroidism in Nonalcoholic Fatty Liver Disease.\nAbstract: Nonalcoholic fatty liver disease (NAFLD) is a leading cause of chronic liver disease with increasing global prevalence. Thyroid dysfunction, particularly hypothyroidism, has been implicated in its pathogenesis and progression. To evaluate the prevalence and pattern of hypothyroidism in NAFLD patients and assess its association with hepatic steatosis and fibrosis severity using imaging and noninvasive fibrosis scoring systems. This cross-sectional observational study was conducted on 158 adult NAFLD patients at a tertiary care hospital in northern India over 1 year. Patients with significant alcohol intake or other chronic liver diseases were excluded. Hepatic steatosis and fibrosis were assessed by ultrasonography and transient elastography, respectively. Fibrosis severity was categorized using FibroScan and the FIB-4 index. Thyroid function was evaluated by serum TSH, FT3, and FT4. Statistical analysis included intergroup comparisons and correlation assessments using SPSS v26, with p < 0.05 considered significant. Among 158 NAFLD patients, 41.14% were hypothyroid. The prevalence of hypothyroidism increased with disease severity: 71.43% in fibrotic NASH and 44.44% in cirrhosis (FibroScan-based). A dose-response trend was observed between steatosis grade and hypothyroidism, reaching 80% in grade 3 steatosis. FT4 showed a significant positive correlation with liver stiffness (r = 0.432, p < 0.001). Additional associations included positive correlations of liver stiffness with urea and INR, and negative correlations with serum protein, fasting glucose, and LDL. Overall, hypothyroidism emerged as a significant cofactor in NAFLD pathogenesis and fibrosis progression. This study demonstrates a strong association between hypothyroidism and both hepatic steatosis and fibrosis in NAFLD. Routine thyroid function screening is recommended in NAFLD patients, particularly those with metabolic syndrome or suspected fibrosis. Early detection and treatment of hypothyroidism may provide therapeutic benefits in slowing or reversing NAFLD progression.\n\nID: 42543476\nTitle: Synergistic bacterial\u2012fungal interactions modulate the fermentation quality and in vitro degradation rate of triticale silage.\nAbstract: The humid climate and frequent rainfall during the harvest season substantially hinder the utilization of triticale as feed. Although ensiling technology can effectively preserve nutrients, its fermentation quality depends on complex microbial interactions, the core mechanisms of which remain unclear. This study proposes and validates the hypothesis that \"bacterial-fungal synergy\" can enhance silage fermentation. By inoculating triticale silage with Aspergillus niger (AN), Lactiplantibacillus plantarum (LP) or their combination (ANLP) and performing multi-omics analyses, the mechanism underlying this synergistic effect was systematically elucidated in this study. Compared with the control treatment, triticale silage inoculated with ANLP presented significant decreases in the neutral detergent fiber (NDF), acid detergent fiber (ADF), and ammonia nitrogen (NH3-N) contents and significant increases in the water-soluble carbohydrate (WSC), crude protein (CP), and lactic acid (LA) contents (P\u2009<\u20090.05). More crucially, ANLP treatment specifically enriched Delftia, indicating a special functional role for this bacterium in triticale silage. Further metabolomic and correlation analyses revealed that the synergy between A. niger and L. plantarum not only promoted the proliferation of Delftia but also activated the phenylalanine, tyrosine, and tryptophan biosynthesis pathways. This activation drove the synthesis of phenolic acid compounds with antimicrobial and antioxidant activities, such as coumaric acid and indole derivatives. These bioactive metabolites effectively inhibited the growth of harmful microorganisms. In vitro digestibility trials confirmed that the ANLP-treated group achieved the highest dry matter and protein degradation rates, thereby validating the pathway from the microbial mechanism to end-use feed value. Overall, the synergistic effects of bacteria (L. plantarum) and fungi (A. niger) can improve the fermentation quality and nutritional content of triticale by promoting amino acid metabolism and increasing the production of bioactive substances, providing a new strategy for increasing its utilization as a feed resource for ruminants.\n\nID: 42543309\nTitle: [Mechanism research of imperatorin in combination with long-wave ultraviolet in inducing cellular senescence through regulating GADD45A/Cyclin B1/CDK1 axis].\nAbstract: This study aims to investigate the phototoxic effects of imperatorin(IMO) and its potential mechanisms of inducing skin photodamage and cellular senescence. A phototoxicity model was established on the dorsal skin of SD rats, which were randomly divided into a control group, an IMO group(0.8 mg\u00b7cm~(-2)), a long-wave ultraviolet A(UVA) group(10 J\u00b7cm~(-2)), and an IMO + UVA group. The rats were continuously observed for 72 h, and Draize skin scores were assessed. Hematoxylin-eosin(HE) staining was used to observe histopathological changes, and Verhoeff-Van Gieson(VVG) staining was utilized to evaluate changes in dermal elastic and collagen fibers. Human dermal fibroblasts(HDF) were cultured in vitro and divided into control, IMO, UVA(1 J\u00b7cm~(-2)), and groups of IMO with low, medium, and high doses(1, 2.5, and 5 \u03bcg\u00b7mL~(-1)) + UVA. The CCK-8 assay was used to assess the cell viability. Transcriptomics by RNA-seq was used to analyze the changes in gene expression. Real-time quantitative PCR(RT-qPCR) was used to detect the mRNA expressions of the top 10 senescence-associated genes. Enzyme-linked immunosorbent assay(ELISA) was used to detect the levels of senescence-associated secretory phenotype(SASP) factors like matrix metalloproteinase-3(MMP-3), interleukin(IL)-6, and IL-8. Immunofluorescence was used to evaluate the senescence-associated heterochromatin foci(SAHF) markers like heterochromatin protein 1\u03b3(HP1\u03b3) and trimethylation of histone H3 at lysine 9(H3K9me3). Senescence-associated \u03b2-galactosidase(SA-\u03b2-gal) staining was performed to detect the senescent cells, and Western blot was used to detect the expression and localization of growth arrest and DNA damage-inducible alpha(GADD45A), G_2/M phase-specific cyclin B1(Cyclin B1), and cyclin-dependent kinase 1(CDK1) proteins. Flow cytometry was used to analyze the cell cycle. The siRNA was used to silence GADD45A gene to verify its function. In vivo results show that, compared to the control group, the IMO + UVA group has significantly higher skin damage scores, with stratum corneum loss, inflammatory cell infiltration, reduced collagen fiber density, and abnormal deposition of elastic fibers. In vitro results demonstrate that IMO + UVA significantly inhibits the cell viability of HDF(P<0.05). RNA-seq and RT-qPCR verifications indicate that IMO + UVA significantly upregulate the expressions of senescence-associated genes, with GADD45A gene showing the most significant change. The IMO + UVA group also shows significant increases in SASP factor secretion, SA-\u03b2-gal activity, SAHF formation, and the proportion of cells in the G_2/M phase(P<0.05). Western blot results demonstrate that IMO + UVA promote the expression of GADD45A protein and inhibit nuclear translocation of Cyclin B1, thereby reducing the kinase activity of the Cyclin B1-CDK1 complex. Silencing GADD45A gene effectively alleviates G_2/M phase arrest and cellular senescence phenotype. In summary, IMO in combination with UVA can induce photodamage to the skin and accelerate cellular senescence, and the mechanism may involve G_2/M phase arrest mediated by the activation of the GADD45A/Cyclin B1/CDK1 axis.\n\nID: 42543059\nTitle: Astaxanthin attenuates skeletal muscle atrophy and mitochondrial dysfunction in streptozotocin-induced diabetic rats.\nAbstract: Diabetes mellitus (DM) induces skeletal muscle atrophy and mitochondrial dysfunction. Although antioxidant supplementation has exhibited beneficial effects on diabetic skeletal muscle, the effects of astaxanthin (AST), a potent antioxidant that protects mitochondrial function, remain unclear. We investigated whether AST supplementation attenuates DM-induced skeletal muscle alterations in streptozotocin (STZ)-induced diabetic rats. Male Wistar rats were assigned to control, DM, and DM\u00a0+\u00a0AST groups. DM was induced via STZ injection, and AST (100\u202fmg/kg/day) was administered orally for 6 weeks. The plantaris muscle was analyzed for morphology, mitochondrial function, oxidative stress, inflammatory status, and signaling pathways related to protein metabolism and atrophy. Diabetic rats exhibited reductions in muscle mass and fiber cross-sectional area, decreases in mitochondrial enzyme activity and mitochondrial protein content, and increased oxidative stress. The expression of pro-inflammatory cytokines was elevated, along with markers associated with ubiquitin-proteasome system-, autophagy-, and apoptosis-related signaling. AST supplementation improved muscle mass and fiber cross-sectional area, partially restored mitochondrial enzyme activity and related protein expression, reduced oxidative stress, and attenuated inflammatory and atrophy-related signaling, without improving hyperglycemia. These findings indicate that AST attenuates DM-induced skeletal muscle atrophy and mitochondrial dysfunction in fast-twitch plantaris muscle. The protective effects of AST appear to be associated with reduced oxidative stress, attenuated inflammation, and attenuation of atrophy-related signaling rather than the restoration of anabolic signaling.\n\nID: 42542867\nTitle: Characterization of the microbiome and polyphenolic compounds in the medicinal plant Dracocephalum tanguticum.\nAbstract: Dracocephalum tanguticum (Maxim) is rich in various chemical constituents and is widely used in traditional Zang medicine. Endophytes play a direct or indirect role in the biosynthesis of active compounds and plant growth. However, little is known about the characteristics of endophytes and polyphenolic compounds in the various organs of D. tanguticum. In this study, high-throughput sequencing and polyphenol-targeted metabolomics were employed to analyze endophytic community diversity and assembly processes, polyphenolic compound content, and their correlations. The results showed that the endophytic compositions of the leaf and stem organs were similar, and significantly different from that in the root organs; however, the endophytic diversity did not differ significantly across the various organs. Actinobacteriota and Pseudomonadota were the dominant bacterial phyla, Ascomycota and Basidiomycota were the dominant fungal phyla in the various organs, while the dominant endophytic genera were significantly different. The endophytic community assembly was influenced mainly by stochastic processes in the various organs. A total of 75 polyphenolic compounds were identified, and the contents of the polyphenolic compounds in the various organs of D. tanguticum differed significantly. The correlation analysis revealed varying degrees of positive and negative correlation between endophytes and polyphenolic compounds. These findings clarify the characteristics of the endophytes and polyphenolic compounds, and lay a theoretical foundation for the identification and application functional microbiomes in the D. tanguticum.\n\nID: 42542304\nTitle: Fermentation-induced changes in Bupleurum: A study on flavonoids, polyphenols, antioxidant capacity, and metabolomic analysis.\nAbstract: Previous studies have indicated that the process of herbal fermentation can enhance the bioactive components of the plant. Bupleurum, a traditional Chinese herb, is used to treat conditions such as colds and inflammation. This study used Bacillus velezensis PV810342 (with strong enzyme production) to ferment Bupleurum aqueous decoction for 48\u00a0h at 0%, 2%, 4%, 6%, 8%, and 10% inoculation rates. A comparative analysis of the Bupleurum aqueous decoction before and after fermentation revealed that the optimal levels of flavonoids (an increase of 62.7%) and polyphenols (an increase of 21.5%) were achieved with a 4% inoculation rate. There was also a 26.6% improvement in hydroxyl radical scavenging capacity and a 42.07% improvement in ferric reducing antioxidant power. However, there was a significant decrease in DPPH radical scavenging capacity. Metabolomic analysis revealed that B. velezensis PV810342 has been observed to modulate glyoxylate and dicarboxylate metabolism, phenylalanine metabolism, and tyrosine metabolism through co-metabolism, thereby influencing the contents of flavonoids, polyphenols, saponins, fatty acids, terpenoids, and alkaloids. Collectively, these findings suggest that Bacillus velezensis-fermented Bupleurum possesses elevated active components and antioxidant activity, suggesting its potential for further development in managing oxidative stress-related conditions.\n\nID: 42541059\nTitle: Assessment of Glycemic Variability in Patients with Polycystic Ovarian Syndrome Using Continuous Glucose Monitoring System.\nAbstract: Polycystic ovarian syndrome (PCOS) predisposes females to metabolic syndrome, diabetes mellitus, and cardiovascular diseases. Continuous glucose monitoring system (CGMS) offers the advantage of better understanding of glycaemic variability as compared to oral glucose tolerance test (OGTT). There is scarce data regarding use of CGMS in understanding glycaemic variability in patients of PCOS. Fifty nondiabetic PCOS patients of age group 16-45 years diagnosed by Rotterdam criteria (2003) were included and subjected to CGM for 72 hours. The mean age of participants was 23.32 \u00b1 4.58 years. Family history of diabetes mellitus in a first degree relative was present in 40% patients. On OGTT, dysglycemia was present in 14 patients-5 (10%) had impaired fasting glucose (IFG), 6 (12%) had impaired glucose tolerance (IGT), and 6 (12%) had both IFG and IGT. Glycemic variability and post prandial glycaemic excursion (PPGE) were found to have significant positive correlation with Luteinizing hormone: Follicle-stimulating hormone (LH: FSH) ratio [r = 0.37 (P = 0.008) and r = 0.39 (P = 0.004)], respectively. Fasting and 2-hour OGTT plasma glucose, serum testosterone, mean blood glucose (MBG), eA1c, total PPGE, and PPGE for breakfast values were significantly higher in patients having homeostatic model assessment insulin resistance (IR) >2.5. MBG, eA1c, and PPGE for lunch and dinner were significantly high in patients with family history (FH) of diabetes mellitus (DM). There was no significant difference in CGM metrics among patients with or without hyperandrogenism (HA). CGMS detected high glycaemic variability and exaggerated post meal glycaemic excursions in Indian non diabetic PCOS patients having either positive family history of diabetes mellitus or IR or higher LH: FSH ratio.\n\nID: 42540517\nTitle: Neurotoxicity of heavy metals across the lifespan: The beneficial role of nutrition from fetus to the elderly.\nAbstract: Heavy metals pose a profound threat to neurological health across all stages of human life, from prenatal development to old age. Heavy metals such as lead, mercury, cadmium, and arsenic are pervasive environmental pollutants that disrupt neural function through mechanisms including oxidative stress, inflammation, mitochondrial dysfunction, and neurotransmitter system imbalances. During critical developmental windows such as fetal growth and early childhood, exposure can impair neurogenesis, synaptic plasticity, and myelination, leading to lifelong cognitive deficits, behavioral disorders, and increased vulnerability to neurodegenerative diseases in later life. Even in adulthood and aging, chronic exposure exacerbates neurodegeneration, accelerating conditions like Alzheimer's and Parkinson's diseases through persistent oxidative damage and inflammatory cascades. This chapter underscores the dual role of nutrition as both a shield and a therapeutic tool against heavy metal neurotoxicity. Key nutrients, such as polyphenols, vitamins, and essential minerals, counteract heavy metal-induced damage by scavenging free radicals, enhancing antioxidant defenses, modulating inflammation, and promoting neuronal repair. By integrating evidence from epidemiological, preclinical, and clinical studies, this chapter emphasizes actionable strategies, such as fortified infant formulas, plant-based proteins, and micronutrient supplementation to reduce heavy metal bioavailability and bolster neurological resilience. Public health initiatives targeting vulnerable populations, alongside policies regulating environmental pollutants, are critical to curbing this silent epidemic. This chapter advocates for a proactive, nutrition-centered approach to safeguarding brain health, demonstrating that dietary interventions are not merely complementary but foundational in combating the pervasive threat of heavy metal neurotoxicity across generations.\n\nID: 42540109\nTitle: Predicting pre-diabetes progression: a systematic review and meta-analysis.\nAbstract: Pre-diabetes is a well-known risk factor for diabetes, a major contributor to morbidity and mortality globally. Identifying patients at highest risk of developing diabetes facilitates early intervention. There is no consensus on diagnostic criteria, with no single modality or range shown to be most predictive of progression to diabetes. This systematic review and meta-analysis aimed to determine which single or combination biochemical test(s) and definition of pre-diabetes best predict progression to diabetes. Following primary screening of 11 980 papers from MEDLINE, Embase and Global Health, 40 original studies published between 2006 and 2024 looking at adults with pre-diabetes were included. Children, pregnant patient populations and groups with significant morbidity were excluded. Risk of bias was assessed with the JBI Critical Appraisal Checklist. Our meta-analysis demonstrated the highest risk of progression to diabetes in the impaired fasting glucose (IFG) 6.1-6.9 mmol/L group, with an HR of 9.0 (4.6 to 13.5). Descriptive statistics identified the combination of IFG 6.1-6.9 mmol/L + impaired glucose tolerance + HbA1c 6.0%-6.4% had the highest percent incidence of diabetes per year, at 15.2%. Generally, combination tests were associated with higher progression rates. Certain single and combination biochemical test combinations may allow better identification of patients with pre-diabetes likely to progress to diabetes. To our knowledge, this is the first systematic review evaluating all testing combinations of these categories in progression and comparing pre-diabetes states as defined by multiple guidelines. This study (PROSPERO CRD42022312640) did not receive funding.\n\nID: 42537713\nTitle: Industrial additive and dietary fiber inulin induces tumor-selective necrotic death via mitochondrial lipid peroxidation involving MYC and YAP.\nAbstract: Inulin as a prebiotic fiber and an industrial additive, has been shown to regulate gut and small intestinal microbiome for health, but non-microbiota-dependent cellular pathways remain unclear. Here we aim to determine how the natural polysaccharide inulin reshapes metabolic stress responses especially in colon cancer cells. In tumor cells treated by inulin, oxidized lipids accumulated in the perimitochondrial region and were accompanied by mitochondrial fragmentation, Golgi dispersion, endoplasmic reticulum (ER) disorganization, lysosomal remodeling, increased mitochondrially encoded cytochrome c oxidase II (MTCO2), and nuclear p21, indicating organelle stress coupled to metabolic reprogramming. Non-malignant cells showed elevated lipid peroxidation but limited necrotic death, consistent with greater metabolic tolerance. YAP/MYC inhibition increased inulin sensitivity. Importantly, ataxia telangiectasia and Rad3-related (ATR) supported stress adaptation, particularly in normal cells. Additionally, inulin decreased nuclear active MYC and YAP and enhanced nuclear androgen receptor (AR). Network pharmacology identified inulin against colon cancer by AR-related hub gene PTGS2 (prostaglandin G/H synthase-2) and validated by a synergistic combination with progesterone. Thus, inulin triggers tumor-selective metabolic stress and disrupts adaptive MYC/YAP, providing a rationale for metabolism-based precision cancer therapy.\n\nID: 42534883\nTitle: Palmitic acid intake in children on gluten-free and generalized diets before and after palm oil reformulation: nutritional and metabolic implications.\nAbstract: The nutritional profile of many gluten-free products can make it challenging for children with celiac disease to maintain a balanced and healthy diet. Among the saturated fatty acids, palmitic acid (C16:0) is often a major component and has been implicated in the modulation of inflammation, insulin resistance, and lipid metabolism. In this study, we evaluated palmitic acid intake and overall dietary quality among school-aged children following gluten-free or unrestricted diets, before and after the widespread adoption of \"no palm oil\" labeling. Using 24-h dietary recalls and food frequency questionnaires, we estimated palmitic acid consumption, macronutrient intake, and key health indicators, including body mass index (BMI) z-scores and the Homeostasis Model Assessment of Insulin Resistance (HOMA-IR). Data collected before 2015 and after 2019 were compared to evaluate the dietary and metabolic changes over time. Overall, 124 individuals were included: 62 on a gluten-free diet and 62 on a gluten-containing diet. Each group had 31 participants assessed before 2015 and after 2019. Following 2019, the mean palmitic acid intake was significantly lower (p < 0.001), particularly among celiac children. After 2019, the main dietary sources of palmitic acid shifted toward natural food, particularly dairy products, consistent with a qualitative improvement in fat intake. Variations in sugar consumption among dietary groups may act as a proxy for broader dietary differences related to palmitic acid intake. The gluten-containing diet group reported higher sugar and fiber intakes. Sugar intake correlated positively with BMI z-scores, whereas palmitic acid intake showed an initial association with HOMA-IR (p < 0.05). These changes suggest a progressive alignment with the Mediterranean dietary model, a widely recognized healthy eating pattern, in both children with celiac disease and healthy controls. This shift supports the role of food reformulation, labeling initiatives, and nutritional education in promoting long-term health benefits.\n\nID: 42534852\nTitle: Plant metabolites targeting mitochondrial dysfunction in cardiovascular diseases: pharmacological mechanisms and combination strategies.\nAbstract: Cardiovascular diseases (CVDs) are closely associated with mitochondrial dysfunction, including impaired mitochondrial biogenesis, abnormal mitochondrial dynamics, excessive oxidative stress, dysregulated mitophagy, and disorders of energy metabolism. Accumulating evidence indicates that natural products exert significant cardioprotective effects by coordinately regulating multiple mitochondrial pathways, thereby alleviating myocardial injury and slowing disease progression. This review systematically summarises recent advances in natural metabolites and their rational combination strategies for cardiovascular diseases, with a particular focus on mitochondrial regulation. Representative metabolites, including flavonoids, alkaloids, saponins, and polyphenols, regulate key signalling pathways such as SIRT1/PGC-1\u03b1, AMPK, Nrf2, PINK1/Parkin, and Drp1/MFN2 to restore mitochondrial homeostasis. Importantly, natural metabolite combinations further demonstrate synergistic and complementary effects through coordinated regulation of distinct mitochondrial pathways. For example, EGCG and Rhein cooperatively alleviate myocardial ischemia/reperfusion injury by simultaneously suppressing oxidative stress and TLR4-mediated inflammatory signalling. Collectively, this review highlights the considerable potential of natural products and their rational combinations as therapeutic strategies for cardiovascular diseases through the modulation of mitochondrial function.\n\nID: 42534730\nTitle: Polyphenols and microglial dynamics in neurodegenerative diseases: mechanistic advances and therapeutic perspectives.\nAbstract: Neuroinflammation plays a central role in multiple neurological and neurodegenerative disorders, including ischemic brain injury, Alzheimer's disease (AD), and Parkinson's disease (PD). Microglia, the principal immune cells with in the central nervous system (CNS) are pivotal mediators of neuroinflammatory responses via their dynamic transition across a spectrum of polarization states, broadly delineated by pro-inflammatory M1-like and anti-inflammatory M2-like phenotypic profiles. A pathological skew towards pro-inflammatory microglial activation drives and exacerbates disease progression, thereby rendering the modulation of microglial polarization states a promising therapeutic target for neuroprotective intervention. Natural polyphenols have garnered increasing interest owing to their capacity to traverse the blood-brain barrier (BBB), confer neuroprotective effects, and mitigate neuroinflammation. Despite challenges in clinical translation stemming from poor bioavailability and rapid in vivo metabolism, innovative delivery systems are being developed to address these limitations. This review consolidates current evidence regarding the mechanisms by which polyphenols modulate microglial phenotypic balance and polarization states and examines advanced delivery strategies designed to enhance their therapeutic efficacy in neuroinflammatory disorders. By synthesizing these perspectives, we offer novel insights into the potential application of polyphenols in neuroprotective therapies targeting pathological neuroinflammation.\n\nID: 42533778\nTitle: Exploring the baru fruit (Dipteryx alata Vog.): chemical composition and health benefits.\nAbstract: Baru (Dipteryx alata Vog.), a native fruit of the Brazilian Cerrado, is gaining increasing scientific attention due to its nutritional value. While its traditional use as a food source for communities in this biome, particularly the almond, is well established, the health benefits of baru have yet to be extensively explored on a broader scale. This study aimed to collect and analyze evidence regarding the nutritional composition of both parts of the baru fruit: (1) pulp and peel, and (2) almond, and their potential effects on human health. The review considered data on chemical composition, alongside studies that investigate health effects. The potential health benefits of baru are significant, underscoring its value as a functional food. The pulp, rich in carbohydrates and insoluble fiber, and the almond, with its high protein content and fatty acid profile, particularly oleic and linoleic acids, stand out. Regarding bioactive compounds, flavonoids are the main compounds identified. Baru is mainly associated with potential prebiotic activity, an improved lipid profile, cardiovascular protection, and reduced oxidative stress. Therefore, this work highlights the potential of baru as a functional food and encourages its incorporation into healthy diets, also contributing to the preservation of Brazilian biodiversity.\n\nID: 42533575\nTitle: Oxytocin receptor neurons in the adBNST modulate maternal-like behavior in mice.\nAbstract: Maternal care plays a pivotal role in the brain and behavioral development of offspring. However, the neural substrates underlying the effects of oxytocin (OT) on maternal-like behavior remain incompletely understood. Using OTR-Cre female mice, fiber photometry was utilized to monitor the calcium signals in oxytocin receptor (OTR) neurons. We observed elevated activity of adBNST (anterodorsal bed nucleus of the stria terminalis) OTR neurons during pup-caring behavior, as indicated by increased calcium signals. Chemogenetic activation of adBNST OTR neurons prolonged duration of licking pups, whereas inhibiting these neurons reduced the time of licking pups and prolonged the latency to retrieve pups. Additionally, microinjection of OT into the adBNST increased the time of licking pups, while administration of an oxytocin receptor antagonist (OTA) suppressed pup-caring behavior. Collectively, these findings not only deepen our understanding of the neural basis underlying maternal-like behavior but also provide a potential target for treating or mitigating aberrant maternal care associated with postpartum depression, anxiety or related disorders. \u6bcd\u6027\u7167\u6599\u5728\u5b50\u4ee3\u5927\u8111\u53d1\u80b2\u53ca\u884c\u4e3a\u53d1\u5c55\u4e2d\u8d77\u7740\u81f3\u5173\u91cd\u8981\u7684\u4f5c\u7528\u3002\u7136\u800c\uff0c\u50ac\u4ea7\u7d20\uff08oxytocin, OT\uff09\u8c03\u63a7\u6bcd\u6027\u6837\u884c\u4e3a\u7684\u795e\u7ecf\u673a\u5236\u5c1a\u672a\u5b8c\u5168\u9610\u660e\u3002\u672c\u7814\u7a76\u5229\u7528 OTR-Cre\u96cc\u6027\u5c0f\u9f20\uff0c\u7ed3\u5408\u5149\u7ea4\u6210\u50cf\u8bb0\u5f55\u6280\u672f\u76d1\u6d4b\u524d\u80cc\u4fa7\u7ec8\u7eb9\u5e8a\u6838\uff08Anterodorsal Bed Nucleus of the Stria Terminalis\uff0cadBNST\uff09\u5185\u50ac\u4ea7\u7d20\u53d7\u4f53\uff08Oxytocin Receptor, OTR\uff09\u795e\u7ecf\u5143\u7684\u9499\u6d3b\u52a8\u3002\u7ed3\u679c\u663e\u793a\uff0c\u5728\u7167\u987e\u5e7c\u5d3d\u8fc7\u7a0b\u4e2d\uff0cadBNST OTR\u795e\u7ecf\u5143\u6d3b\u52a8\u663e\u8457\u5347\u9ad8\u3002\u901a\u8fc7\u5316\u5b66\u9057\u4f20\u5b66\u6fc0\u6d3b\u50ac\u4ea7\u7d20\u53d7\u4f53\u795e\u7ecf\u5143\u53ef\u5ef6\u957f\u5bf9\u5e7c\u5d3d\u7406\u6bdb\u7684\u65f6\u95f4\uff1b\u800c\u6291\u5236\u8fd9\u4e9b\u795e\u7ecf\u5143\u5219\u7f29\u77ed\u5bf9\u5e7c\u5d3d\u7406\u6bdb\u7684\u65f6\u95f4\u5e76\u5ef6\u957f\u8854\u56de\u5e7c\u5d3d\u7684\u6f5c\u4f0f\u671f\u3002\u6b64\u5916\uff0c\u5411adBNST\u5fae\u91cf\u6ce8\u5c04OT\u53ef\u589e\u52a0\u5bf9\u5e7c\u5d3d\u7684\u7406\u6bdb\u65f6\u95f4\uff0c\u800c\u7ed9\u4e88\u50ac\u4ea7\u7d20\u53d7\u4f53\u62ee\u6297\u5242\uff08Oxytocin Receptor Antagonist\uff0cOTA\uff09\u5219\u6291\u5236\u6bcd\u672c\u6837\u884c\u4e3a\u3002\u7efc\u4e0a\u6240\u8ff0\uff0c\u8fd9\u4e9b\u7814\u7a76\u7ed3\u679c\u4e0d\u4ec5\u52a0\u6df1\u4e86\u6211\u4eec\u5bf9\u6bcd\u6027\u884c\u4e3a\u795e\u7ecf\u57fa\u7840\u7684\u7406\u89e3\uff0c\u8fd8\u4e3a\u6cbb\u7597\u6216\u7f13\u89e3\u4ea7\u540e\u6291\u90c1\u3001\u7126\u8651\u53ca\u76f8\u5173\u75be\u75c5\u6240\u5f15\u53d1\u7684\u5f02\u5e38\u6bcd\u6027\u7167\u6599\u884c\u4e3a\u63d0\u4f9b\u4e86\u6f5c\u5728\u9776\u70b9\u3002.\n\nID: 42533389\nTitle: Diosgenin Alleviates Age-Related Sarcopenia by Promoting Satellite Cell Proliferation and Myogenic Differentiation via Activation of the SIRT1/PGC-1\u03b1 Signaling Pathway.\nAbstract: Age-related sarcopenia is characterized by a progressive decline in skeletal muscle mass and function, with satellite cell dysfunction representing a central pathogenic mechanism. Diosgenin, a steroidal saponin derived from plants of the Dioscorea genus, has demonstrated potential anti-aging properties; however, its role in sarcopenia remains unclear. In this study, naturally aged C57BL/6J mice and a D-galactose (D-gal)-induced senescent C2C12 cell model were employed to systematically investigate the effects of diosgenin on muscle function, satellite cell dynamics, and the sirtuin 1 (SIRT1)/peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PGC-1\u03b1) signaling pathway. Diosgenin treatment significantly improved forelimb grip strength and exercise endurance, increased the gastrocnemius muscle index, and enlarged muscle fiber cross-sectional area in aged mice. Mechanistically, diosgenin upregulated the expression of myokines meteorin-like protein (METRNL) and insulin-like growth factor 1 (IGF-1) at both mRNA and protein levels, increased the number of proliferative satellite cells positive for paired box\u00a07 (Pax7) and Ki67, and enhanced the expression of myogenic markers, including myogenic factor 5 (Myf5), Pax7, and myosin heavy chain II (MyHC II). These effects were mediated by direct activation of SIRT1, leading to deacetylation of PGC-1\u03b1. Notably, pharmacological inhibition of SIRT1 with EX527 markedly abrogated the diosgenin-induced effects. Molecular docking and cellular thermal shift assays further confirmed the direct interaction between diosgenin and SIRT1. Collectively, these findings demonstrate that diosgenin alleviates age-related sarcopenia by activating the SIRT1/PGC-1\u03b1 signaling pathway to promote satellite cell proliferation and myogenic differentiation, highlighting its potential as a promising therapeutic candidate for sarcopenia.\n\nID: 42531785\nTitle: Curdlan alleviates non-alcoholic fatty liver disease by enriching butyrate-producing gut microbiota-liver axis.\nAbstract: The gut microbiota-liver axis is a critical target for non-alcoholic fatty liver disease (NAFLD) intervention, yet effective strategies to restore gut microbiota balance and mitigate hepatic metabolic inflammation remain limited. Curdlan, a Food and Drug Administration-approved microbial exopolysaccharide, is widely used as a food additive, but its role in modulating the gut-liver axis to combat NAFLD has never been explored. Here, we demonstrate that curdlan alleviates high-fat and fiber-deficient (HFFD) diet-induced NAFLD by orchestrating gut microbiota remodeling and enhancing gut-liver crosstalk associated with the enrichment of butyrate-producing bacteria. In the mouse model of NAFLD, curdlan significantly attenuated hepatic steatosis, inflammation, and M1 macrophage infiltration. Hepatic transcriptome analysis revealed that curdlan modulated immune response and metabolism pathways, as further evidenced by the improvement of the NF\u03baB-PTP1B-Akt signaling axis. Crucially, curdlan reversed gut barrier disruption by enhancing tight junction proteins and enriching butyrate-producing genera (Clostridium_sensu_stricto_1, Anaerovorax, Roseburia, Turicibacter, and others), thereby increasing serum butyrate levels. Integrative correlation analysis revealed a significant correlation between butyrate-producing bacteria, increased serum butyrate levels, reduced serum lipopolysaccharide, and downregulated hepatic proinflammatory cytokines. Strikingly, Clostridium butyricum supplementation recapitulated the protective effects of curdlan, suggesting a role for butyrate in mediating gut-liver interactions. These findings establish curdlan as a novel prebiotic and metabolic modulator with therapeutic potential for NAFLD and support the translational application of functional food additives in metabolic disease management.\n\nID: 42531634\nTitle: Bile salt hydrolase-active bifidobacterium animalis improves sarcopenia via the gut microbiota-bile acid-FXR-FGF15 axis and its functional fermented milk preparation.\nAbstract: Sarcopenia is a major global health challenge associated with aging, and effective pharmacological treatments are lacking. This study investigated how bile salt hydrolase (BSH)-active probiotics alleviate sarcopenia through bile acid deconjugation and remodeling, activating the intestinal FXR-FGF15/19 signaling pathway, and explored their application in functional dairy products. Three high-BSH strains-Lactiplantibacillus plantarum H-87, Bifidobacterium animalis F1-7, and F1-3-2-were identified, among which F1-7 and F1-3-2 showed superior efficacy in a dexamethasone-induced sarcopenia model. These strains improved muscle mass, morphology (including increased muscle fiber cross-sectional area and improved histological integrity), and performance by modulating gut microbiota, optimizing bile acid composition, and enhancing ileal FXR-FGF15 signaling to activate the muscle FGFR4/KLB pathway and inhibit protein degradation. Furthermore, fermented milk produced with F1-7 and F1-3-2 met quality standards and exhibited improved sensory properties. This study provides a mechanistic basis for developing probiotic dairy products and sustainable nutritional strategies for sarcopenia.\n\nID: 42531287\nTitle: Verbascoside triggers apoptosis and ferroptosis in NSCLC by targeting BCAT2.\nAbstract: The treatment of non-small cell lung cancer (NSCLC) has challenges such as drug resistance and recurrence. Concurrently, the induction of apoptosis and ferroptosis is a promising therapeutic strategy. This study aimed to investigate whether the natural product, verbascoside, induces apoptosis and ferroptosis in NSCLC cells by targeting BCAT2. Bioinformatic analysis was used to predict the potential targets of verbascosides. Stable cell lines with BCAT2 knockdown and overexpression were constructed. The effects of verbascoside on NSCLC were evaluated in vitro and using a mouse xenograft model. Bioinformatics screening and molecular docking identified BCAT2 as a potential target of verbascoside, with a significantly stronger binding energy (-7.8 kcal/mol) than another candidate, PARP1. In vitro and in vivo experiments confirmed that BCAT2 knockdown significantly inhibited NSCLC cell viability, induced apoptosis and ferroptosis, and induced mitochondrial damage. Conversely, BCAT2 overexpression produced opposite effects. Verbascoside treatment inhibited BCAT2 expression in a concentration-dependent manner, recapitulating the apoptotic, ferroptotic, and mitochondrial damage phenotypes induced by BCAT2 knockdown; however, BCAT2 overexpression significantly reversed these effects of verbascoside. In an animal model, treatment with verbascoside significantly suppressed tumor growth and activated apoptosis and ferroptosis in tumor tissues by downregulating BCAT2. Verbascoside can induce apoptosis and ferroptosis in NSCLC by directly targeting and inhibiting BCAT2, leading to mitochondrial dysfunction. This finding not only reveals BCAT2 as a novel target of verbascoside but also confirms its ability to induce apoptosis and ferroptosis in NSCLC cells.\n\nID: 42530553\nTitle: Exploring multi-omics approaches in (poly)phenol research for precision nutrition.\nAbstract: Multi-omics approaches are gaining importance across numerous research fields, including nutritional studies on (poly)phenols (PPs), plant bioactive compounds with recognised health benefits but still unclear mechanisms of action. To date, most PP investigations have focused on mono- or dual-omics analyses; however, integrating multiple omics layers is crucial to fully elucidate their biological and mechanistic effects. This review outlines current omics strategies and their integration in PP research, emphasizing how these approaches can help improving our understanding and lead to more efficient applications. Furthermore, we report the growing importance of integrative multi-omics approaches in nutritional research, with particular regard to the inter-individual variability in PP metabolism. Finally, we discuss the pivotal role of these approaches in precision nutrition, providing insights on how integrative multi-omics approaches may enhance tailored nutritional interventions and unlock new possibilities to foster human health.\n\nID: 42530491\nTitle: Giving structure meaning: Modelling the cellular synapse of excitation-contraction coupling in skeletal muscle.\nAbstract: Ca2+-ions, stored in a muscle fiber's SR, are rapidly released during electrical activity of the cell membrane to activate force, a process termed excitation-contraction coupling (EC coupling). In this process, the narrow junctional gap between the membrane of the transverse tubules (TT), which conduct the surface action potential into the fiber volume, and the membrane of the terminal cisternae of the SR has to be bridged. The publication by Rios and Pizarro in this journal issue (https://doi.org/10.1085/jgp.202613968) offers a model inspired by structural data that comprehensively explains many aspects of the coupling process.\n\nID: 42529971\nTitle: TrxR Inhibition and Nrf2-FOXO3 Modulation by Repurposed Drugs: A Redox Strategy to Reverse Cancer Multidrug Resistance.\nAbstract: A common cause of multidrug-resistant (MDR) cancer is imbalanced redox signaling, which reduces the effectiveness of chemotherapy and promotes regrowth of cancer cells. Amplification of thioredoxin reductase (TrxR) and activation of the Keap1-Nrf2-FOXO3 pathway may contribute to enhanced drug efflux, strengthens antioxidant defenses, and resistance to oxidative stress-induced apoptosis in certain tumors. Redox-based drug repurposing offers a promising strategy to overcome MDR by targeting these shortcomings. Repurposing drugs including metformin, auranofin, brusatol, and natural polyphenols increase reactive oxygen species (ROS) and make MDR cells more sensitive to chemotherapy via modulation and inhibiting Nrf2 or TrxR. Nanotechnology advancements and combination of repurposed drugs with anticancer drugs, ferroptosis inducers may improve tumor selectivity while lowering systemic toxicity. Preclinical experiments show effectiveness by suppressing antioxidant pathways, inhibiting efflux pump function, and delivering drugs in a redox-responsive manner. Next-generation tumor-selective delivery systems, adaptive clinical trial designs, and biomarker-driven patient classification based on TrxR expression or Keap1/Nrf2 mutations are the main areas of focus. Translation into clinical practice could be accelerated by combining specific redox profiling, nanocarrier technologies, and pharmacokinetics. For MDR cancer, redox-targeted drug repurposing is an effective, precision-based strategy for recovering chemosensitivity and enhancing treatment outcomes.\n\nID: 42529805\nTitle: Dietary polyphenols in colorectal cancer\u00a0-\u00a0Mechanisms, clinical evidence, and bioavailability of curcumin, resveratrol, and epigallocatechin-3-gallate: A review.\nAbstract: Dietary polyphenols have attracted considerable interest as potential preventive and therapeutic agents in colorectal cancer (CRC), although their clinical value remains uncertain. This narrative review aimed to critically evaluate the mechanistic, epidemiological, and clinical evidence for curcumin, resveratrol, and epigallocatechin-3-gallate (EGCG), with particular emphasis on the gap between preclinical activity and human efficacy. PubMed/MEDLINE, Scopus, and Web of Science were searched for English-language studies published from January 2000 to January 2026, including in vitro and animal investigations, epidemiological studies, and clinical trials. Preclinical evidence consistently showed that these polyphenols inhibit nuclear factor kappa B (NF-\u03baB), phosphoinositide 3-kinase/protein kinase B/mechanistic target of rapamycin (PI3K/Akt/mTOR), signal transducer and activator of transcription 3 (STAT3), and Wnt/\u03b2-catenin signaling, while promoting apoptosis, antioxidant responses, and suppression of inflammation, proliferation, angiogenesis, and metastasis. These effects were associated with reduced tumor burden in animal models. Epidemiological studies suggested modest protective associations, particularly for green tea consumption, but findings were inconsistent, frequently confounded, and of limited generalizability. Human trials predominantly demonstrated biomarker modulation, whereas effects on adenoma recurrence were mixed and no consistent benefits were observed for tumor regression, recurrence, progression-free survival, or overall survival. Clinical translation is further limited by poor absorption, rapid metabolism, uncertain activity of metabolites, formulation variability, and potential hepatotoxicity and drug interactions, although high local colorectal exposure may remain biologically relevant. Curcumin, resveratrol, and EGCG therefore show strong mechanistic potential but cannot currently be recommended as stand-alone CRC therapies. They should be regarded as investigational preventive or adjunctive agents pending adequately powered randomized trials using standardized formulations, optimized dosing, and clinically meaningful endpoints.\n\nID: 42529124\nTitle: National divergence in cardio-kidney-metabolic syndrome burden and implications for health policy: a global burden of disease analysis with projections to 2050.\nAbstract: The co-occurring epidemics of diabetes and obesity have increased the prevalence of Cardio-Kidney-Metabolic (CKM) syndrome. Comparative studies on long-term trends of its three core components [ischemic heart disease (IHD), diabetic kidney disease (DKD), non-alcoholic fatty liver disease (NAFLD)] across major countries are still limited. We analyzed age-standardized disability-adjusted life year (DALY) rates of IHD, DKD, and NAFLD attributable to high fasting plasma glucose (HFPG) from 1990 to 2021 among seven representative middle-and high-income countries using Global Burden of Disease 2021 data. We assessed temporal trends, conducted hierarchical clustering, and projected burdens to 2050. We found substantial cross-country heterogeneity. From 1990 to 2021, IHD burden decreased significantly in the United States and Japan, while trends in China and India showed high uncertainty (coefficients of variation >100%) and should be interpreted with caution. DKD burden increased in Saudi Arabia and the United States but decreased in China. NAFLD burden increased in Saudi Arabia, the United States, India, and South Africa, while declining in China and Japan. Cluster analysis identified three patterns: \"High IHD Burden\" (India), \"High Metabolic Burden\" (Saudi Arabia), and \"Low-Moderate Burden\" (other countries). HFPG was associated with the largest share of DKD burden (Population Attributable Fraction [PAF] >80%) and a substantially smaller share of NAFLD burden (PAF <11%).Projections to 2050 show a sharp rise in DKD in the United States and India, together with increasing NAFLD burden, indicating a shift toward metabolic organ damage. The burden of CKM syndrome is substantial and dynamic, with marked cross-country differences. These findings support the need for integrated, multi-organ risk management strategies for metabolic disorders.\n\nID: 42528838\nTitle: The diet-microbiota-inflammation axis and colorectal cancer.\nAbstract: Colorectal cancer (CRC) is still one of the leading causes of cancer morbidity and mortality worldwide. There is increasing evidence that diet, gut microbiota, microbial metabolites and chronic inflammation are important factors in colorectal carcinogenesis and may provide novel opportunities for prevention, diagnosis and treatment. To provide a comprehensive review of the current evidence on the role of diet, nutrition, microbial metabolism and chronic inflammation in CRC, with emphasis on emerging translational applications including microbiome-based biomarkers and microbiota-targeted therapeutic strategies. A literature search was performed with PubMed, Scopus and the Cochrane Library. Relevant studies on diet-microbiota interactions, microbial metabolites, inflammatory mechanisms, colorectal carcinogenesis, microbiome-derived biomarkers, and microbiota-targeted interventions were identified and reviewed. Preclinical and clinical studies and high quality reviews and meta-analyses were considered. Dietary patterns have been shown to have a major impact on the composition and function of the gut microbiota. Rich-fiber diets and short-chain fatty acids (SCFAs) production seem protective against CRC, while western dietary patterns, ultra-processed foods and dysbiosis-associated metabolites promote a pro-inflammatory environment associated with carcinogenesis. Some microorganisms such as Fusobacterium nucleatum, enterotoxigenic Bacteroides fragilis and pks-positive Escherichia coli have been associated with CRC by inflammatory, genotoxic and immune-modulatory mechanisms. Recent advances in sequencing technologies and multi-omics approaches have enabled the identification of microbial signatures with potential diagnostic and prognostic value. Moreover, microbiota-targeted interventions such as probiotics, prebiotics, postbiotics, faecal microbiota transplantation, and next-generation microbial therapies have yielded promising preclinical and early clinical results. The diet-microbiota-inflammation axis is a key player in colorectal carcinogenesis and a promising target for translational research. Microbiome-based biomarkers and microbiota-targeted therapies may have a role in future precision prevention and personalised management strategies of colorectal cancer despite significant challenges in terms of causation, standardisation and translation into clinical practice.\n\nID: 42528510\nTitle: Dietary fibers to boost endogenous GLP-1 secretion and satiety: a scoping review.\nAbstract: Dietary fibers can stimulate endogenous glucagon-like peptide-1 (GLP-1) secretion through microbial fermentation and gut hormone signaling, potentially enhancing satiety and supporting weight management. Given the growing interest in non-pharmacological strategies to complement or support tapering of GLP-1 receptor agonist therapy, a structured overview of the human evidence is needed. A pre-registered scoping review was conducted using PubMed, Scopus and Cochrane Central. Randomized controlled trials in adults assessing circulating GLP-1 concentrations and satiety following supplementation with a single, well-defined dietary fiber were included. Fiber types were categorized based on structural characteristics. Outcomes were summarized qualitatively across fiber categories. In total, 1049 papers were screened and 49 publications comprising 52 studies (total n=1,085 participants; median sample size per study=19) were included. Most studies were acute interventions (71%) and conducted in Western populations. Studies reporting increased GLP-1 showed a non-significant tendency to also report increased satiety (OR\u00a0=\u00a02.95, 95% CI: 0.87-9.98). Dextrins stood out as one of the few fiber categories showing robust effects on both GLP-1 (4 positive studies) and satiety (5 positive studies). Other fibers, such as \u03b2-glucans and mannans, showed more uniform effects on satiety or GLP-1, respectively, but did not consistently affect both outcomes simultaneously. Although these findings identify dextrins as a promising dietary fiber candidate for future research, the evidence remains constrained by small sample sizes, short interventions, and substantial heterogeneity. Longer-term studies in free-living conditions, including periods of GLP-1 receptor agonist tapering, are needed to capture microbiota adaptation and generate robust real-world evidence. https://osf.io/cnw4e/overview.\n\nID: 42558291\nTitle: IL-33 promotes efferocytosis by peritoneal macrophages by a mechanism associated with rapid granulocyte IL-13 production.\nAbstract: Resolution of inflammation is an active process that requires efferocytosis, the engulfment of apoptotic cells by macrophages, mediated by receptors such as MerTK. IL-33 is an alarmin that initiates type 2 immune responses, including increased production of IL-13, which promotes MerTK expression. The ability of IL-33 to promote efferocytosis in vivo was examined. Intraperitoneal administration of IL-33 to mice increased local MerTK+ macrophage numbers within 48h. MerTK+ macrophages were not similarly induced by free mitochondria, an alternative cell damage associated signal. Efferocytotic activity was increased rapidly in response to apoptotic thymocytes in IL-33-treated mice. The established inducer of MerTK expression, IL-13, was detected in peritoneal lavage fluid shortly after IL-33 administration. Peritoneal eosinophils expressed the IL-33 receptor and demonstrated both intracellular IL-13 by flow cytometry and significantly increased Il13 transcript expression following IL-33 treatment. In contrast, neither elevated IL-13 expression nor IL-13 protein secretion was observed in peritoneal lymphocyte populations within the first 6 hours after IL-33 administration. Primary cultures of bone marrow-derived mouse mast cells and eosinophils demonstrated IL-13 protein responses to IL-33 administration within 6\u00a0h. Mast cell-deficient Cpa3-Cre; Mcl-1fl/fl mice had significantly reduced IL-13 levels in the peritoneal cavity 3 hours after IL-33 administration when compared with mast cell-containing littermates. In contrast, IL-33-treated eosinophil-deficient \u0394dblGATA mice had similar levels of IL-13 at this time point as wild type controls. These data demonstrate that IL-33 promotes MerTK expression, critical for efferocytosis by macrophages, by a process associated with an early rapid local increase in IL-13 production to which mast cells are a substantial early contributor. These findings contribute to our understanding of clinical situations where elevated soluble IL-33 receptor (sST2) and/or lower mast cell numbers are associated with worse clinical outcome.\n\nID: 42550891\nTitle: Adenosine 2A receptor drives microglial efferocytosis to accelerate white matter repair and functional recovery after stroke.\nAbstract: Although reperfusion therapy effectively restores blood flow to occluded brain arteries after ischemic stroke, many patients develop persistent white matter injury, a major contributor to long-term neurological disability. Currently, there are few approved clinical therapies that specifically target white matter repair to enhance functional recovery after stroke. We demonstrated that microglial adenosine 2A receptor (A2AR) is essential for spontaneous white matter regeneration after ischemic injury in mice. Deletion of A2AR in microglia specifically impaired chronic-phase repair without altering the severity of acute ischemic injury. Pharmacological activation of A2AR signaling with blood-brain barrier-permeable agonistic micelles during the early reperfusion phase enhanced white matter structural repair and led to sustained improvements in cognitive and sensorimotor function in mice. Mechanistically, A2AR activation promoted microglial efferocytosis of apoptotic cells and myelin debris in the lesioned white matter, thereby limiting secondary necrosis-induced inflammation, enhancing neurotrophic factor release, and establishing a reparative microenvironment conducive to oligodendrocyte precursor cell differentiation and remyelination. Moreover, A2AR signaling engaged HIF1\u03b1-dependent metabolic reprogramming to increase glycolysis, thereby providing the energetic support required for efficient and sustained efferocytosis. Together, these findings identify A2AR as a critical regulator of microglia-mediated white matter repair and a promising therapeutic target for enhancing regeneration after stroke.\n\nID: 42548269\nTitle: Time of day effects of high-intensity interval resistance training on metabolism, adiposity, and adipogenic markers in male mice.\nAbstract: The circadian system regulates physiological and metabolic processes, and exercise timing may influence metabolism and adiposity. To investigate the time-of-day effects of high-intensity interval resistance training (HIRT) on metabolism, adiposity, and adipogenic markers, male Swiss mice (n\u2009=\u2009111) were allocated to control or HIRT groups during the light (C6 and T6) or dark phase (C18 and T18). HIRT was performed for 8\u2009weeks (3 sessions/week) on a ladder at 90% of maximal load until exhaustion. Metabolic biomarkers, adiposity, adipocyte morphology, and protein expression of PPAR\u03b3 and adiponectin were assessed. Maximal strength increased in trained groups. Training-time interactions were observed for triglycerides and total cholesterol, with higher values in T6 than in C6 and T18. Glucose and PPAR\u03b3 were higher during the dark phase. PPAR\u03b3 was also higher in trained than control groups, irrespective of the time of day. HIRT reduced adiposity across multiple depots regardless of training time. No significant differences were observed for adipocyte area, adiponectin, insulin, or HOMA-IR. HIRT reduced adiposity independently of training time, suggesting that chronic adaptations in adipose tissue were primarily driven by the training. However, time of day modulated metabolic responses, particularly lipid metabolism.\n\nID: 42544671\nTitle: [Integrative Multi-omics Analysis of the Tnf-Pnpla2-Rictor-Nr1d1 Network Underlying the Hemostatic Action of Bletilla Striata].\nAbstract: By integrating transcriptomics and network pharmacology, we systematically investigated the potential hemostatic mechanism of Bletilla striata (BS). Thirty SPF-grade Kunming mice were randomly divided into three groups (n =10 per group): Control group, Model group, and BS group. The BS group was orally administered Bletilla striata extract (2.48 g/kg) for 7 consecutive days, while the Control and Model groups received an equal volume of 0.5% sodium carboxymethyl cellulose (CMC-Na) solution. On day 7, the Model and BS groups were injected via the tail vein with heparin sodium (0.8 U per mouse) to inducesystemic bleeding. The bleeding time (BT) was measured by tail tip amputation, and coagulation parameters including prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), and plasma fibrinogen (FIB) were measured using a semi-automaticcoagulation analyzer. Liver tissues were collected for total RNA extraction and transcriptome sequencing to identify differentially expressed genes (DEGs) related to coagulation pathways. Network pharmacology was used to construct aprotein-protein interaction (PPI) network, screen hub genes, and perform molecular docking to evaluate the binding affinity between the active component militarineand key target proteins. Compared with the Model group, preventive treatment with BS significantly shortened BT and CT (P <0.01), and reversed coagulation parameters: APTT, PT, and TT were significantly reduced (P <0.01), while FIB levels were significantly elevated P <0.001). Transcriptome analysis showed that the hepatic gene expression profile in the BS group was closer to that of the Control group. Network pharmacologyidentified Tnf, Rictor, Nrld1 , and Pnpla2 askey hub genes involved in the hemostaticprocess, all of which exhibited favorable binding affinity with militarine. Compared to the control group, the Model group showed a significant decrease in hepatic Tnf expression but significant increases in Rictor, Nr1d1 , and Pnpla2. After preventive intervention with Bletilla striata , the hepatic Tnf expression in the mice was significantly increased compared to the Model group, while Rictor, Nr1d1 , and Pnpla2 significantly decreased. These findings were further validated by RT-PCR and molecular docking analyses.

As pregnancy progresses and levels of apoptotic placental cells increase, macrophage efferocytosis remains essential to maintain a healthy pregnancy. There is mounting evidence that dysfunctional macrophage efferocytosis is implicated in the pathogenesis of multiple pregnancy complications. This includes disorders of malplacentation such as preeclampsia and fetal growth restriction, wherein impaired spiral artery remodelling and inflammation in the decidua impairs placental vascularisation leading to maternal hypertension, or impaired fetal growth. As a shift in macrophage phenotype and cytokine secretion is required for the onset of labour, alterations in phenotype earlier in pregnancy may be associated with preterm birth. In more rare pregnancy complications such as chronic histiocytic intervillositis (CHI), impaired efferocytosis and wound healing by infiltrating intervillous macrophages may contribute to their excessive recruitment into the intervillous space, hindering placental function. In this review, we describe the importance of efferocytosis by various maternal macrophage populations in the placenta and review the evidence of how impaired efferocytosis contributes to pathology. Furthermore, therapeutic targeting of macrophage efferocytosis and how this may be used to prevent or treat obstetric conditions is explored.\n\nID: 42528667\nTitle: Effects of endurance exercise on skeletal muscle and liver metabolic health in male rats with different fitness under chronic circadian rhythm disruption.\nAbstract: Circadian rhythm (CR) disruption is a major risk factor for metabolic dysfunction in skeletal muscle and liver. Although endurance training (ETR) is known to improve metabolic health, it remains unclear whether exercise timing and training duration influences metabolic adaptations under CR disruption. Twenty-four male Sprague-Dawley rats were randomly assigned to four groups: regular sleep cycle sedentary (RSC), irregular sleep cycle sedentary (ISC), irregular sleep cycle with late-stage ETR (ISE), and irregular sleep cycle with prolonged ETR (IEE). CR disruption was induced by alternating light-dark cycles every three days for 20 weeks. ETR was performed at moderate intensity. Skeletal muscle and liver samples were analyzed for circadian clock proteins, mitochondrial biogenesis, glucose and lipid metabolism, oxidative stress, and fibrosis-related markers. CR disruption significantly impaired circadian clock regulation, mitochondrial biogenesis, and metabolic function in both skeletal muscle and liver. Specifically, reductions in BMAL-1 expression, AMPK activation, PGC-1\u03b1 signaling, and oxidative phosphorylation were observed, along with disrupted glucose and lipid metabolism. These alterations were accompanied by increased oxidative stress, hepatic lipid accumulation, and fibrosis-related markers. ETR effectively attenuated these changes. Notably, training initiated prior to CR disruption (or a higher fitness maintained during CR disruption) group (IEE) resulted in greater improvements in mitochondrial and metabolic adaptations compared with shorter-duration training (ISE). In contrast, no significant differences were observed between ISE and IEE in oxidative stress and fibrosis-related outcomes. Endurance training mitigates CR disruption-induced metabolic dysfunction in skeletal muscle and liver. Prolonged training exposure enhances mitochondrial and metabolic adaptations, whereas protective effects on oxidative stress and fibrosis may occur even with shorter training duration. These findings highlight the importance of exercise timing and training duration in optimizing metabolic resilience under circadian disruption.\n\nID: 42521405\nTitle: Impact of Grape Seed Extract on Flavor and Functionality of Pea Protein Extrudates and Patties.\nAbstract: Consumer interest in plant-based proteins is increasing, but undesirable off-flavors from Maillard reaction and lipid oxidation processes hinder their broader acceptance. Our previous work showed that proanthocyanidin-rich plant extracts like grape seed extract (GSE) could reduce the formation of these off-flavors in aqueous plant protein solutions. This study investigated the effects of GSE addition pre- and post-extrusion at two levels (0.02% and 1.0% w/w) on off-flavor development in pea protein extrudates and patties. We hypothesized that GSE addition at different processing phases would impact its ability to alter Maillard reaction and lipid oxidation processes, thus affecting its ability to mitigate off-flavor formation. Pre-extrusion treatments reduced Maillard-associated browning products by 40% more than post-extrusion treatments, potentially due to greater protein-polyphenol interactions during extrusion-induced protein denaturation and restructuring. Conversely, post-extrusion GSE treatment decreased primary and secondary lipid oxidation products by approximately 53% and 44% in patties, respectively (vs. 15% and 31%, respectively, in pretreated samples), and enhanced antioxidant capacities across all samples. Because post-extrusion GSE treatments exhibited fewer apparent protein-polyphenol interactions, a larger proportion of polyphenols may have remained chemically available for radical scavenging. Sensory evaluation suggests that GSE did not impart astringency, a common concern with polyphenol addition. These results indicate that polyphenols may be a promising strategy for improving flavor quality in plant-based protein products. PRACTICAL APPLICATIONS: Addition of grape seed extract can help reduce off-flavors in legumes caused by major flavor degradation pathways. Adding polyphenols before processing can reduce Maillard-derived off-flavors, while polyphenols added after processing are more effective at reducing lipid oxidation-derived off-flavors. This approach offers a simple and sustainable way to enhance flavor quality and properties of plant-based meat alternatives.\n\nID: 42520678\nTitle: Dual role of macrophage heterogeneity in allergic inflammation: from mechanism to targeted therapy.\nAbstract: Allergic inflammation, such as allergic asthma, allergic rhinitis, and atopic dermatitis, shares many pathogenic hallmarks, including inappropriate activation of type 2 immune responses, tissue barrier dysfunction, and disruption of local homeostasis. Due to their remarkable plasticity and tissue adaptability, macrophages are crucial effector cells of the innate immune system that play complex, context-dependent dual roles in allergic inflammation. On the one hand, macrophages are implicated in the persistence of chronic inflammation, thereby boosting Th2 cell recruitment, eosinophil infiltration, antigen processing, chemokine secretion, inflammatory mediator release, and tissue remodeling. On the other hand, they promote the resolution of inflammation by triggering barrier repair, producing anti-inflammatory mediators including TGF-\u03b2 and IL-10, and phagocytosing apoptotic cells. Recent single-cell transcriptomic and functional studies have demonstrated that macrophages are dynamically distributed along an activation continuum rather than merely fitting into the traditional M1/M2 polarization. Functional states are determined by cellular origin, illness stage, tissue niche, and complex regulatory networks. For macrophages implicated in airway inflammation and remodeling, non-IgE-dependent nasal neurogenic reflexes, skin barrier disruption, itch neuroimmune circuits, and inflammation resolution, distinct barrier tissues-such as the lung, nasal mucosa, and skin-show notable tissue specificity. The pathogenic and preventive functions of macrophages in allergic inflammation are systematically summarized in this review, which also emphasizes a continuous spectrum of macrophage activation and incorporates interactions among metabolic reprogramming, pyroptosis, epigenetic control, and trained immunity. Given the dynamic and microenvironment-dependent nature of macrophage function, future treatment approaches need to shift from broad anti-inflammatory therapies to precision reprogramming that is stage-specific and tissue-tuned. During the start and amplification stages of inflammation, therapeutic strategies should target pathogenic M2a-like programs, chemokine networks, monocyte recruitment, and excessive pyroptotic responses. On the other hand, M2b/M2c and pro-resolving macrophage-mediated efferocytosis, immunological tolerance, and tissue healing should be the focus of tactics in the resolution and repair stages. Furthermore, the management of allergic diseases may shift from empirical anti-inflammatory therapy to mechanism-guided precision interventions through patient stratification based on single-cell omics, spatial omics, and macrophage-associated biomarkers.\n\nID: 42514304\nTitle: Olive Oil as a Modulator of Gut Microbiota and Intestinal Health: A Narrative Review from Microbial Metabolism to Host Responses.\nAbstract: Olive oil, particularly virgin (VOO) and extra-virgin olive oil (EVOO), is a central component of the Mediterranean diet and has been associated with cardiometabolic, anti-inflammatory, and intestinal health benefits. Increasing evidence suggests that these effects may involve interactions with the gut microbiota, intestinal barrier, and host inflammatory pathways. This narrative review summarizes current evidence on the impact of olive oil, olive-derived phenolics, and olive oil-rich dietary patterns on gut microbiota modulation, barrier function, inflammatory bowel diseases, and related systemic outcomes. The available literature indicates that olive oil may interact with the gut ecosystem through both its oleic acid-rich lipid matrix and its minor phenolic fraction. VOO and EVOO appear more consistently associated than refined oils with microbial or microbial metabolite profiles related to saccharolytic metabolism, short-chain fatty acid production, mucus-layer dynamics, and anti-inflammatory intestinal environments. Olive-derived phenolics, including hydroxytyrosol, tyrosol, oleuropein derivatives, and oleocanthal, can undergo microbial biotransformation and may influence bile acid metabolism, epithelial barrier integrity, and inflammatory signaling. Whole EVOO evidence is strongest in experimental colitis models, whereas human evidence mainly supports effects on postprandial endotoxemia, lipid oxidation, and selected inflammatory markers. However, findings remain heterogeneous and depend on oil quality, phenolic composition, comparator fat, dietary context, and host condition. Well-controlled human studies directly comparing EVOO, VOO, refined olive oil, and oleic acid-rich controls are needed to clarify reproducible microbiota-mediated effects and their relevance to intestinal and systemic health.\n\nID: 42514215\nTitle: Camellia japonica Seed Oil Fermented by Sporidiobolus pararoseus Prevents Skin Cellular Photoaging by Inducing Autophagy.\nAbstract: Camellia japonica L. (Theaceae) seed oil is an essential component for skin protection, attributed to its antioxidant properties and anti-aging effects. In this study, Camellia japonica seed oil underwent fermentation with Sporidiobolus pararoseus (Fell & Tallman, CGMCC No. 39106, commercial name: Longevity yeast of 1021-year-Camellia japonica). The post-fermented oil, designated Longevity Yeast Oil (LYO), was used in the present research. Gas chromatography-mass spectrometry analysis demonstrated that methyl esterification of LYO afforded twelve fatty acid methyl esters. We used an aging model in human epidermal keratinocytes and human skin fibroblasts exposed to ultraviolet B (UVB) to explore the anti-skin aging effects and mechanisms of LYO. The results of the CCK-8 assay demonstrated that LYO exhibited no cytotoxicity but instead displayed potential proliferative activity, indicating its excellent safety profile. Quantitative real-time polymerase chain reaction analyses confirmed that LYO downregulated the expression of autophagy marker p62 and upregulated LC3B, thereby activating the autophagic pathway. Further investigation revealed that LYO protected against UVB-induced apoptosis, promoted the synthesis of collagen and elastin, and upregulated the expression of loricrin, filaggrin, and ceramides, effectively reversing UVB-induced skin cellular aging. Notably, we further revealed that LYO alleviated UVB-induced cutaneous photoaging via activating cellular autophagy pathway. In conclusion, LYO demonstrated biocompatibility and conferred protection to skin cells against photoaging, thereby establishing a theoretical basis for the development of innovative autophagy-targeted anti-aging therapies.\n\nID: 42510742\nTitle: The Biological Clock-Mitochondria Axis in the Liver: From Molecular Mechanisms to Metabolic Disease.\nAbstract: The liver ranks among the peripheral organs exhibiting the most robust circadian rhythmicity, with glucose homeostasis, lipid metabolism, and bile acid turnover governed by tightly phased diurnal oscillations. Mitochondria execute these programs, their output coordinated with the hepatocyte circadian state. The mitochondrial network undergoes dynamic remodeling across the 24 h cycle, encompassing oscillatory changes in bioenergetics, fusion-fission balance, and quality control. This interplay is bidirectional: core clock components drive rhythmic remodeling via cyclin-dependent kinase 1/mitogen-activated protein kinase (CDK1/MAPK)-dependent phosphorylation of dynamin-related protein 1 (DRP1) and the NAD+-SIRT1/SIRT3 axis, while retrograde signals modulate clock amplitude and entrainment. Circadian disruption is associated with mitochondrial dysfunction implicated in MASLD onset and progression to MASH and HCC, though this evidence remains largely correlative and derives predominantly from rodent models. This review integrates clock-mitochondria coupling with metabolic liver disease. Restoring this coupling has been proposed as a candidate chronotherapeutic strategy, supported by preliminary rhythmicity data in primary human hepatocytes and a hepatocellular carcinoma cell line, though causal validation in healthy human liver is lacking. Time-restricted feeding, NAD+ precursors, PPAR agonists, and ACC inhibitors converge on clock-regulated pathways and may benefit from circadian-informed timing, though this remains unverified.\n\nID: 42508211\nTitle: Short-term parental exposure to diazepam disrupts development, behavior, and transcriptional profiles in zebrafish offspring.\nAbstract: Diazepam (DZP) is a pervasive emerging contaminant known to induce significant sublethal adverse effects in aquatic species. However, the intergenerational impacts of parental DZP exposure on fish offspring remain poorly understood. In this study, we exposed zebrafish (F0) to DZP at 8 \u03bcg/L for 7 days and investigated variation in the development, behavior, and transcriptional profiles of their offspring (F1) reared in DZP-free medium. The results suggest that DZP accumulates in F0 ovaries and is vertically transmitted to F1 embryos, resulting in-ovo exposure. The parental DZP exposure significantly increased F1 embryo mortality and accelerated their hatching. Moreover, parentally DZP-exposed F1 larvae exhibited reduced locomotor activity and increased exploratory behavior. Transcriptomic analysis identified 404 differentially expressed genes, which were significantly enriched in KEGG pathways related to metabolism and organismal systems. In parentally DZP-exposed F1 larvae, transcriptional responses in the pathways of xenobiotic biodegradation and metabolism were driven primarily by key genes encoding detoxification enzymes, and the activation of lipid metabolism pathways was underpinned by the up-regulated expression of vital apolipoprotein-encoding genes. Conversely, circadian rhythm suppression was characterized by coordinated downregulation of clock and cryptochrome genes. Overall, these findings provide preliminary insights into the intergenerational toxicity induced by parental DZP exposure, offering potential molecular clues for future studies on its ecotoxicological effects on the fish population.\n\nID: 42505335\nTitle: In Vitro Release of Curcumin and Resveratrol from Polymeric Systems: Films and Hydrogel.\nAbstract: Chronic wounds are a persistent clinical and public health challenge due to impaired tissue repair caused by sustained inflammation, oxidative stress, and cellular senescence. Natural polyphenols such as curcumin and resveratrol, alongside mesenchymal stem cell (MSC) secretome, have demonstrated complementary anti-inflammatory, antioxidant, and pro-angiogenic properties with potential for wound healing. This study reports two complementary in vitro investigations evaluating the release profiles of curcumin and resveratrol from two polymeric platforms: poly(vinyl alcohol)/sodium alginate/carboxymethylcellulose films (Study 1) and an acrylate copolymer-based hydrogel incorporating MSC secretome (Study 2). UV-Vis spectrophotometric analysis confirmed analytical selectivity with no interference from excipients. Resveratrol exhibited progressive and consistent release from the hydrogel. Curcumin compromised polymer matrix integrity and reduced resveratrol release efficiency. Also showed unsatisfactory release in both systems, attributed to its low aqueous solubility. These results support the use of resveratrol-loaded polymeric matrices as promising sustained-release platforms for bioactive wound dressings and highlight the need for nanoencapsulation strategies to improve curcumin bioavailability.\n\nID: 42498074\nTitle: Defective m6A RNA Modification in Macrophages Exacerbates Inflammation and Promotes Colitis-Associated Carcinogenesis by Impairing Efferocytosis.\nAbstract: Chronic inflammation resulting from unresolved tissue injury is a potent driver of tumorigenesis. Macrophages are essential for efferocytosis, the clearance of apoptotic cells, which prevents secondary necrosis and promotes inflammation resolution. However, the epigenetic mechanisms regulating this process under inflammatory stress remain incompletely understood. Here, we identify the m6A methyltransferase METTL3 as a critical regulator of macrophage efferocytosis. Using various models of tissue injury, METTL3 expression was significantly downregulated in macrophages under inflammatory conditions and was associated with defective efferocytosis, the accumulation of apoptotic cells, and exacerbated chronic inflammation. Mechanistically, we reveal that METTL3-mediated m6A modification promotes IGF2BP2/3-dependent stabilization of MFGE8 mRNA, a process that is compromised upon METTL3 deficiency. In a colitis-associated cancer model, the efferocytosis defect associated with Mettl3 deficiency exacerbated chronic inflammatory tissue injury and increased susceptibility to colitis-associated cancer. Ultimately, external administration of recombinant MFGE8 protein effectively rescued the efferocytosis defect, mitigated inflammation, and reduced tumor burden in the AOM/DSS model. Collectively, our findings identify the METTL3-m6A-IGF2BP2/3-MFGE8 pathway as an important regulator of macrophage efferocytosis that may contribute to inflammation-associated carcinogenesis. These results suggest that targeting the METTL3-MFGE8 axis may represent a strategy for restoring efferocytosis and promoting inflammation resolution in chronic inflammatory diseases and inflammation-associated malignancies.\n\nID: 42486499\nTitle: The triple-hit hypothesis: exploring pulmonary e-cigarette, PM2.5 and viral polyexposure.\nAbstract: Exposure to e-cigarette aerosols, particulate matter with aerodynamic diameter \u22642.5 \u00b5m (PM2.5) and respiratory viruses rarely occurs in isolation, but rather in complex polyexposure contexts during daily life. On a cellular and molecular level, vaping induces a distinct lipid-laden macrophage phenotype, alters pulmonary neutrophilic infiltration and impairs epithelial differentiation and ciliary function. In contrast, PM2.5 alters the macrophage polarisation equilibrium, temporally favouring an acute pro-inflammatory phenotype and a subsequent chronic tissue-remodelling phenotype, while also driving an oxidative inflammatory epithelial milieu. Both exposures thus impair antiviral defences and enhance susceptibility to respiratory viral infections such as influenza A, rhinovirus and severe acute respiratory syndrome coronavirus 2. The triple-hit hypothesis proposes that concurrent exposure to vaping aerosols, PM2.5 and respiratory viruses may exert additive or synergistic effects on chronic airway inflammation. PM2.5 may amplify vaping-induced macrophage lipid accumulation, thereby reducing the macrophage clearance capacity. Decreased efferocytosis and autophagy may further exacerbate inflammation by increasing secondary necrosis from apoptotic cells and debris. This persistent inflammatory state coupled with epithelial injury and impaired antiviral responses may increase the risk of infection and accelerate the development or progression of chronic respiratory diseases such as asthma and COPD. These insights highlight the crucial need for polyexposure models to accurately reflect real-world environmental and behavioural exposures and evaluate their impact on respiratory health and disease exacerbations. Understanding this exposure triad is also crucial for refining exposure guidelines, updating risk assessments and implementing preventive strategies.\n\nID: 42483195\nTitle: Efferocytosis-associated Mrc1+Gas6+ macrophages are linked to abdominal aortic aneurysm progression through ERK-associated dysfunction.\nAbstract: Abdominal aortic aneurysm (AAA) is a progressive vascular disease characterized by chronic inflammation, extracellular matrix degradation, and aortic wall remodeling, yet effective pharmacological therapies remain lacking and how macrophage state heterogeneity contributes to disease progression and defective inflammation resolution remains incompletely understood. We combined single-cell RNA sequencing of elastase-induced murine AAA with pathway, cell-cell communication, trajectory, and regulon analyses, and validated key findings in vivo by immunostaining and flow cytometry and in vitro by pharmacologic ERK inhibition, gene-expression analysis, and macrophage efferocytosis assays. Single-cell transcriptomic analysis identified four macrophage subsets in AAA, comprising Thbs1+Spp1+ inflammatory macrophages, Mrc1+Gas6+ efferocytosis-associated macrophages, Cdca8+ proliferative macrophages, and Cd36+Lpl+ lipid-handling macrophages. AAA progression was characterized by expansion of Thbs1+Spp1+ macrophages and emergence of Cdca8+ macrophages, together with relative loss of Mrc1+Gas6+ and Cd36+Lpl+ macrophages. Thbs1+Spp1+ macrophages showed inflammatory, chemotactic, oxidative stress, and metabolic remodeling signatures, whereas Mrc1+Gas6+ macrophages were enriched for efferocytosis- and homeostasis-associated features but exhibited increased apoptosis-related signals and reduced expression of Mertk, Gas6, and Igf1 during AAA progression. ERK signaling was overactivated in AAA and associated with loss of these effectors and impaired macrophage efferocytosis, whereas ERK inhibition restored Mertk, Gas6, and Igf1 expression and enhanced uptake of apoptotic cells in macrophage-line models. Trajectory and regulon analyses further suggested that inflammatory and efferocytosis-associated macrophages follow distinct state trajectories, with Maf emerging as a candidate regulator of the Mrc1+Gas6+ program. AAA is characterized by an imbalance between inflammatory and efferocytosis-associated macrophage states. ERK-associated dysfunction of Mrc1+Gas6+ macrophages may contribute to defective inflammation resolution and represents a potential therapeutic target in aneurysmal disease.\n\nID: 42479460\nTitle: Efferocytosis activates a DNMT3A-mediated oxidized DNA repair pathway to enable tissue resolution.\nAbstract: Efferocytosis, the clearance of apoptotic cells by macrophages, promotes tissue resolution. Efficient resolution requires efferocytosis-induced macrophage proliferation (EIMP) to expand pro-resolving macrophages. Here, we show that efferocytosis activates base excision repair (BER) to remove 8-OHdG from DNA, enabling EIMP. Mechanistically, efferocytosis promotes poly(ADP-ribose) polymerase-1 (PARP1) chromatin binding and PARylation to facilitate DNA repair complex assembly, and increases nuclear MTH1/NUDT1, which hydrolyzes 8-OHdG. Both processes require DNA-methyltransferase-3A (DNMT3A), which is activated during efferocytosis. Using a model where dexamethasone-induced thymocyte apoptosis triggers efferocytosis-mediated thymic repair, we showed that DNMT3A is required for increases in nuclear PARP1/MTH1, oxidized DNA suppression, EIMP in thymic macrophages, and thymic repair. We next studied a human-relevant model of atherosclerosis regression, where efferocytosis drives protective lesional fibrous cap thickening. We compared WT mice with a model of DNMT3A-clonal hematopoiesis (CH), in which loss-of-function DNMT3A mutations promote atherosclerotic disease. Atherosclerosis regression in WT mice led to decreased nuclear 8-OHdG and increases in nuclear PARP1/MTH1 and EIMP in lesional macrophages and fibrous cap thickening, all of which were impaired in DNMT3A-CH regression. These findings reveal that efferocytosis initiates a BER pathway to allow macrophage proliferation for tissue resolution, with possible therapeutic relevance to atherosclerosis regression and DNMT3A-CH.\n\nID: 42470880\nTitle: Thermal degradation mechanism of myricetin in palmitic acid.\nAbstract: Dietary polyphenols are susceptible to degradation during high-temperature cooking, yet their transformation behavior in lipid-rich frying systems remains poorly understood. The thermal stability and degradation of myricetin in a simplified palmitic acid model under frying-relevant conditions was investigated. Myricetin degraded rapidly at 180 \u00b0C but remained relatively stable at 120 \u00b0C. UPLC-QTOF-MS/MS, supported by density functional theory calculations, suggested that myricetin transformation is temperature-dependent but primarily governed by lipid oxidation-derived radical and carbonyl chemistry. Vitamin C markedly delayed myricetin degradation by suppressing radical initiation and limiting o-quinone-centered downstream reactions. These findings highlight lipid oxidation as a key determinant of polyphenol stability during frying and clarify the protective role of antioxidants in lipid-rich thermal processing systems.\n\nID: 42468854\nTitle: Beta-2-microglobulin augments neutrophil phagocytosis of bacteria and apoptotic cells.\nAbstract: Polymorphonuclear leukocytes (PMNs), predominantly neutrophil granulocytes, are key components of the innate immune system that eliminate invading pathogens through phagocytosis and clear apoptotic cells through efferocytosis. Beta-2-microglobulin (\u03b22m) is best known as the light chain of major histocompatibility complex class I (MHC I), where it is required for antigen presentation to CD8\u207a T cells. However, emerging evidence suggests that extracellular \u03b22m may also regulate innate immune responses. Here, we show that extracellular \u03b22m enhances neutrophil phagocytosis and efferocytosis. Addition of soluble \u03b22m (50 \u00b5g/ml) increased phagocytosis of latex beads by PMNs from 23% to 31%, whereas the proteolytically cleaved variant desLys58-\u03b22m (dK58\u03b22m) had no effect. In contrast, both \u03b22m and dK58\u03b22m enhanced phagocytosis of the Gram-positive bacterium Streptococcus pyogenes and the Gram-negative bacterium Acinetobacter baumannii by >3.6-fold. Furthermore, both \u03b22m variants promoted efferocytosis of apoptotic Jurkat cells in a dose-dependent manner, resulting in up to a two-fold increase that was comparable to the effect of GM-CSF. Cytochalasin D abolished \u03b22m-mediated uptake of apoptotic cells. Pre-incubation of latex beads with \u03b22m followed by washing did not enhance phagocytosis, and pre-incubation of PMNs with \u03b22m followed by washing did not enhance subsequent efferocytosis of apoptotic cells. These findings indicate that \u03b22m does not act by coating phagocytic targets or by inducing sustained neutrophil priming. Collectively, these findings identify extracellular \u03b22m as a regulator of neutrophil-mediated phagocytosis and efferocytosis and demonstrate that proteolytic processing differentially influences these activities.\n\nID: 42468599\nTitle: Mechanically adaptive hydrogels reprogram apoptotic cell clearance to prevent tissue fibrosis.\nAbstract: Abnormal mechanical stimulation drives fibrotic scar formation in active wounds by sustaining mechanotransduction, promoting apoptotic cell accumulation and pro-fibrotic amplification that constrain functional regeneration. To address this challenge, we developed a mechanically adaptive hydrogel patch (Gel/VP) through the integration of an interpenetrating polymer network and CNC@PDA@ZIF8 dynamic nanofillers, in which the interpenetrating network provides structural load-bearing and adaptive deformation, while the nanofillers form a force-induced, reconfigurable dissipative network via hydrogen bonding and \u03c0-\u03c0 interactions, collectively dissipating tensile energy upon pre-stretched application, establishing a reverse mechanical buffer at the wound interface, suppressing sustained Piezo1-YAP activation, restoring macrophage efferocytosis-mediated apoptotic cell clearance, and ultimately limiting fibrotic scar formation. The interpenetrating architecture endows the patch with a tunable elastic window matched to the mechanical environment of skin (elastic modulus of 7-15 kPa with twofold extensibility). Under reverse mechanical buffering, the macrophage phagocytic rate increases from 22.50% to 64.50%, significantly enhancing apoptotic cell clearance. In vivo, the patch achieves near-complete wound closure (>95%) within two weeks, markedly reduces \u03b1-SMA+ myofibroblast accumulation, promotes ordered collagen remodeling, and substantially decreases scar formation. Overall, by leveraging material-mediated reverse stress buffering to restore macrophage efferocytosis, this study targets apoptotic cell clearance at an early stage of fibrosis and provides a robust antifibrotic material strategy for the functional regeneration of active wounds. STATEMENT OF SIGNIFICANCE: Abnormal mechanical stretching during wound healing is a key yet underrecognized driver of fibrotic scar formation, and current therapies rarely address this physical cue. Here, we develop a stress-adapted hydrogel patch that forms a \"reverse mechanical buffer\" under pre-stretch, actively redistributing tensile forces at the wound interface. This buffering suppresses mechanotransduction (Piezo1-YAP signaling) while restoring macrophage-mediated clearance of apoptotic cells. By integrating an interpenetrating polymer network with dynamic nanofillers, the material achieves adaptive energy dissipation and mechanical compatibility with skin. This work establishes a mechanically guided, immunomodulatory approach to limit fibrosis, offering a promising biomaterials strategy for scarless healing and functional tissue regeneration.\n\nID: 42462036\nTitle: Restored clearance of senescent neutrophils by tissue-resident macrophages limits organ aging.\nAbstract: Aging disrupts tissue homeostasis across organ systems. Here, we identify tissue-resident macrophages (TRMs) as central coordinators of age-related organ decline through impaired clearance of senescent neutrophils, a process regulated by the immunomodulatory prostaglandin E2 (PGE2) receptor EP2. Reducing TRM EP2 signaling in aged mice preserved youthful mitochondrial fitness and prevented cognitive decline, frailty, sarcopenia, adiposity, cardiac impairment, and systemic inflammation. Plasma proteomics implicated the liver as a major source of age-associated immune change, in which reduced TRM EP2 signaling rescued neutrophil efferocytosis and prevented paracrine stress in neighboring cells. Elevated TRM EP2 expression and senescent neutrophils were also observed in aged and diseased human tissues. Pharmacologic EP2 inhibition restored youthful neutrophil clearance, establishing impaired TRM efferocytosis as a reversible driver of organ decline in aging.\n\nID: 42461367\nTitle: Lipidomics and proteomics in MASLD: reading the molecular script toward precision therapeutics.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) is increasingly recognized as a multisystem disorder characterized by complex metabolic, inflammatory, and fibrogenic interactions. Advances in lipidomics and proteomics have substantially refined understanding of MASLD pathophysiology by revealing how qualitative alterations in lipid species and dynamic protein signaling networks contribute to disease initiation and progression. Bioactive lipids, including ceramides and free cholesterol, promote lipotoxicity, mitochondrial dysfunction, inflammasome activation, and fibrosis, while proteomic analyses have identified key pathways involved in inflammation, cellular senescence, and hepatic stellate cell activation. Emerging translational evidence further suggests that modern pharmacological agents may modulate these molecular signatures beyond their metabolic effects. Integrating lipidomic and proteomic data may therefore facilitate improved disease stratification, biomarker discovery, and the development of mechanism-based therapeutic strategies, supporting a transition toward precision medicine in MASLD.\n\nID: 42455861\nTitle: Peroxisomal import is circadian in glia and regulates sleep and lipid metabolism.\nAbstract: Peroxisomes are critical organelles that detoxify cellular waste while also catabolizing and anabolizing lipids. How peroxisomes coordinate protein import and support metabolic functions across complex tissues and timescales remains poorly understood in vivo. Using the Drosophila brain, we discover a striking enrichment of peroxisomes in the neuronal soma and the cortex glia that enwrap them. Unexpectedly, import of peroxisomal proteins into cortex glia, but not neurons, oscillated across time and peaked in the early morning. Rhythmic peroxisomal import in cortex glia autonomously required the circadian clock and Peroxin 5 (Pex5; peroxisomal biogenesis factor 5 homolog), with import persistently elevated in clock mutants. Notably, reducing Pex5 in cortex glia, but not neurons, caused hyperactivity and reduced total sleep. Moreover, brain lipid metabolism was dramatically altered upon Pex5 knockdown, with glia impacting sphingolipids and triacylglycerols, and neurons impacting phospholipids. The cell-type specificity of these Pex5 phenotypes highlights unique roles for peroxisomal import in both sleep and lipid metabolism in the brain.\n\nID: 42450524\nTitle: Encapsulation Strategies for Natural Bioactives in Clean-Label Meat Preservation: A Review.\nAbstract: The increasing demand for clean-label meat products has accelerated interest in natural bioactive compounds, including essential oils, plant polyphenols, and bacteriocins, as alternatives to synthetic preservatives. These compounds have the potential to enhance product safety and shelf life while meeting consumer expectations. Many natural bioactives exhibit antioxidant and antimicrobial activities, enabling them to reduce lipid oxidation and inhibit the growth of spoilage and pathogenic microorganisms in meat systems. Despite these benefits, their practical application remains limited by instability, volatility, poor solubility, and undesirable sensory effects. Encapsulation technologies have emerged as effective approaches to overcome these limitations by enhancing stability, controlling release behavior, and improving compatibility with complex meat matrices. This review synthesizes evidence from 154 studies published between 2010 and 2026 on the application of encapsulation technologies, including microencapsulation, nanoemulsions, liposomes, and cyclodextrin-based systems, for natural bioactives in meat systems. Encapsulated bioactive delivery systems are evaluated by integrating spoilage mechanisms, delivery system design, and application strategies. Encapsulation approaches are discussed in terms of structure-function relationships, release behavior, and interactions with meat components. Application strategies, including direct incorporation, edible coatings, and active packaging, are comparatively analyzed based on their functional performance in meat systems. Overall, nanoscale delivery systems are particularly effective in improving the dispersion, stability, and functional performance of hydrophobic bioactives, while controlled-release systems offer prolonged protection but often exhibit reduced predictability when translated from model systems to real meat matrices. Current challenges related to scalability, cost, regulatory constraints, sensory impact, industrial implementation, and the safe design of sustained-release antimicrobial systems are also addressed, thereby providing a framework for the rational development and implementation of effective clean-label preservation strategies in meat systems.\n\nID: 42450375\nTitle: AI-Integrated Multi-Target Validation of Coreopsis tinctoria Polyphenols as a Functional Food Ingredient Against Diabetic Nephropathy.\nAbstract: Diabetic nephropathy (DN) is a severe diabetic complication with substantial clinical burden. The complex pathogenesis of DN has hindered the development of targeted therapies, creating an urgent need to develop novel strategies that directly address its underlying inflammatory and fibrotic mechanisms. Coreopsis tinctoria (CE) is an edible plant rich in polyphenols, but its mechanism against DN remains understood. An integrated framework combining network pharmacology and machine learning was developed to prioritize active polyphenols and their targets. A multi-layer perceptron classifier, trained on 3.16 million compound-target pairs from Binding DB, predicted interactions between 36 CE polyphenols and 12,030 DN-associated genes. The top 100 targets were subjected to KEGG enrichment analysis, and the identified pathways were validated in a high-fat diet/STZ-induced DN rat model. The MLP model achieved superior performance (AUC-ROC = 0.9219, AP = 0.9592). Five lead polyphenols (flavonoids/chalcones) showed high predicted activity. KEGG analysis revealed enrichment in PI3K-Akt, calcium signaling, metabolic pathways, and cellular senescence. In vivo, CE treatment (150-600 mg/kg/day) dose-dependently improved glucose/lipid metabolism and renal function, and ameliorated histopathological damage, including glomerular hypertrophy, fibrosis, and mesangial expansion. Mechanistically, CE suppressed NF\u03baB/TGF\u03b2/Smad signaling, restored PPAR\u03b3 and Nrf2/HO-1/FoxO1 antioxidant defenses, and inhibited apoptosis via Bcl-2/Bax regulation. CE exerts multi-target renoprotective effects through coordinated modulation of metabolic, inflammatory, fibrotic, and antioxidant pathways, supporting its potential as a functional food ingredient for DN management.\n\nID: 42449574\nTitle: FABP7: A Regulator of Neuro-Immune Metabolic Networks and Therapeutic Vulnerabilities in Glioma.\nAbstract: Fatty acid-binding protein 7 (FABP7) is a multifunctional lipid chaperone that is enriched in radial glia and astrocytes within the central nervous system (CNS) and is frequently upregulated in glioma. Beyond its established roles in glial development, lipid homeostasis, and circadian regulation, growing evidence positions FABP7 at the intersection of tumor metabolism, neuronal activity, and immune modulation in the brain. In this review, we integrate the physiological functions of FABP7 in glial cells with its tumor-intrinsic and microenvironmental roles in glioma. We summarize how gliomas co-opt FABP7-dependent metabolic, transcriptional, and post-transcriptional programs to promote stemness, lipid remodeling (e.g., altered fatty acid composition, lipid droplet formation, and lipid peroxidation resistance), inflammatory signaling, and invasive growth, including nuclear FABP7-mediated transcriptional activation linked to oncogene status. Furthermore, we discuss the role of FABP7 in shaping the tumor-neuro-immune interface, including regulating immunosuppressive gene networks, pro-tumoral macrophage polarization, resistance to T-cell-induced ferroptosis and immunotherapy, and tumor microtube-mediated integration into neuronal circuits to support glioma progression. Finally, we highlight therapeutic opportunities and challenges, including small-molecule FABP7 inhibitors, brain-directed delivery strategies, chronotherapeutic considerations, and combination approaches with immunotherapy. Collectively, this work positions FABP7-centered metabolic, circadian, and neuro-immune networks as potential vulnerabilities in glioma, linking fundamental glial biology to glioma therapeutics.\n\nID: 42446910\nTitle: Macrophage Dicer1 deletion delays skin wound healing in mice by promoting pentose phosphate pathway activity.\nAbstract: Macrophages play a pivotal role in skin wound healing through efferocytosis, the clearance of apoptotic cells, which is essential for inflammation resolution and tissue repair. This study aims to investigate the role of macrophage Dicer1 in skin wound healing in mice and to explore the regulatory mechanism underlying efferocytosis. Dorsal skin wounds were created in Dicer1-deficient and wild type mice, and the wound areas were quantified daily. In the wounds, epithelialization, granulation tissue growth, collagen deposition, angiogenesis, and the mRNA levels of inflammatory cytokines were measured and apoptotic cells were labelled. In vitro, macrophages were separated from the wounds, and the expressions of pentose phosphate pathway (PPP)-related molecules were measured; wound macrophages were cocultured with apoptotic Jurkat cells, then the phagocytosis was analyzed, and the mRNA levels of inflammatory cytokines and PPP-related molecules were measured in the macrophages. Macrophage-specific deletion of Dicer1 impairs skin wound healing in mice, resulting in delayed wound closure, reduced re-epithelialization and granulation tissue formation, diminished collagen deposition, and attenuated angiogenesis. Dicer1-deficient wounds exhibited sustained inflammation, alongside increased apoptotic cell accumulation. Mechanistically, Dicer1 knockout in macrophages led to impaired efferocytosis and upregulated PPP activity. These findings identify the Dicer1-PPP-efferocytosis axis as a critical regulator of macrophage function during wound repair. Our study provides novel insights into the molecular basis of impaired wound healing and suggests that targeting the macrophage Dicer1-PPP-efferocytosis axis may offer therapeutic potential for skin wounds.\n\nID: 42439678\nTitle: Follistatin Mitigates Atherosclerosis Through Activation of Arginine Metabolism and Adipose Browning.\nAbstract: Follistatin (FST) binds to and neutralizes members of the transforming growth factor-beta (TGF-\u03b2) superfamily, thereby regulating diverse physiological processes, including regulation of skeletal muscle, adipose, and bone homeostasis. FST also promotes adipose browning and enhances energy metabolism, leading to improved plasma lipid profiles and metabolic health in mice. Given the emerging association between brown adipose tissue (BAT) activation and reduced atherosclerosis, we investigated the anti-atherogenic potential of FST. Transcriptomic and metabolomic analyses of the Hybrid Mouse Diversity Panel (HMDP) revealed that Fst expression was negatively correlated with aortic lesion area and positively correlated with the expression of multiple adipose browning-associated genes. Adeno-associated viral delivery of Fst (AAV1-FST344) in Ldlr-/- mice significantly reduced aortic lesion area, improved plasma lipid profiles, and decreased expression of adhesion (VCAM1) and inflammatory (iNOS, TNF-\u03b1) markers in white adipose tissue (WAT), liver, and heart. Fst gene delivery also markedly increased uncoupling protein 1 (UCP1) expression in WAT, consistent with WAT browning. Integrated correlation analyses of Fst expression with tissue metabolites, together with plasma metabolite-lesion associations identified in the HMDP, implicated the arginase 1 (Arg1)-mediated metabolic pathway as a key regulator of atherogenesis. Consistent with these findings, Arg1 expression was significantly elevated in WAT, liver, and heart of AAV1-FST344-treated mice and in wild-type versus Fst-knockout mouse embryonic fibroblasts (MEFs). Immunostaining localized Arg1 predominantly to CD68+ macrophages in heart and liver. Given recent evidence identifying Arg1 as a novel mediator of efferocytosis, these findings suggest that Arg1 may promote macrophage metabolic reprogramming and resolution of inflammation by enhancing the clearance of apoptotic cells. Furthermore, Fst gene delivery increased the expression of fibroblast growth factor 21 (Fgf21) and adiponectin (AdipoQ) in WAT. Collectively, these findings identify Fst as a novel anti-atherogenic regulator that protects against vascular disease by promoting adipose browning, improving lipid metabolism, and activating Arg1-mediated metabolic pathways.\n\nID: 42439247\nTitle: Quality Characteristics and Storage Stability of Mixed Fresh Sausages Produced With Meat From Culled Sheep Fed Flaxseed for Different Periods.\nAbstract: The utilization of meat from aged sheep is often limited by inferior sensory attributes and technological challenges in processed products. Nutritional strategies such as flaxseed supplementation may improve meat quality and lipid stability. This study evaluated the effects of flaxseed feeding duration and sheep ratios on the physicochemical composition, oxidative stability, color, texture, and consumer preference of mixed fresh sausages produced from the meat of aged sheep (>5\u00a0years) during 21\u00a0days of refrigerated storage at 4\u00b0C. Sausages were formulated with different sheep ratios (100:0, 90:10, 80:20, and 70:30) using meat from culled sheep supplemented with 15% flaxseed for 30, 45, or 60\u00a0days before slaughter. Flaxseed feeding period and formulation did not affect moisture, protein, ash content, or water activity (p\u00a0>\u00a00.05). However, increasing the flaxseed supplementation period from 30 to 60\u00a0days significantly improved the lipid composition of the sausages by reducing lipid content, increasing polyunsaturated fatty acids (PUFAs) and \u03c9-3 fatty acids, and decreasing the \u03c9-6/\u03c9-3 ratio. During refrigerated storage, pH and lipid oxidation increased, whereas water activity decreased (p\u00a0<\u00a00.05). Despite the higher PUFA content associated with longer supplementation periods, oxidative stability was maintained, with TBARS values remaining below levels commonly associated with sensory deterioration throughout the 21-day storage period. Increasing the proportion of sheep meat reduced lipid content, and all formulations met low-fat product criteria. Preference ranking results showed significant differences among formulations, while the relative preference order remained stable throughout refrigerated storage and across flaxseed supplementation periods. Color parameters were not affected by flaxseed supplementation but were influenced by formulation. Texture parameters were mainly affected by storage time, with increased hardness and chewiness observed during refrigerated storage. In conclusion, extending flaxseed supplementation from 30 to 60\u00a0days improved the nutritional lipid profile of sausages without compromising oxidative stability, color, texture, or consumer preference during 21\u00a0days of refrigerated storage. The preference ranking results further indicated that consumer preference patterns were maintained throughout storage, supporting the feasibility of incorporating culled sheep meat into low-fat fresh sausage formulations while adding value to this underutilized raw material. PRACTICAL APPLICATIONS: Meat from old or culled sheep can be effectively used in the production of mixed fresh sausages with good physicochemical stability and sensory acceptance during refrigerated storage. Sausage formulations containing 70%-80% sheep meat combined with pork allow the development of low-fat products without compromising texture, color, or oxidative stability. Flaxseed supplementation is used as a nutritional strategy to increase omega-3 fatty acids and improve the \u03c96/\u03c93 ratio in meat, contributing to improved nutritional quality. Flaxseed supplementation in the sheep diet does not negatively affect product quality and can be implemented without technological limitations. This feeding strategy may also enhance the fatty acid profile without requiring changes in meat processing conditions. This approach provides a practical alternative for valorizing low-market-value sheep meat, reducing waste, and supporting the development of cost-effective and nutritionally acceptable processed meat products for the food industry.\n\nID: 42438369\nTitle: Internal Circadian Misalignment of the Human Metabolome Links Night Shiftwork to Metabolic Impairment.\nAbstract: Circadian misalignment, as experienced during shiftwork, impairs glucose metabolism and body weight regulation, yet the underlying biochemical mechanisms remain incompletely understood. Characterizing how circadian misalignment alters circulating metabolites provides a promising avenue to help identify these mechanisms. Although data from metabolomics studies have identified circulating metabolites with daily rhythms, it is not comprehensively known which rhythms shift during circadian misalignment and whether such shifts relate to metabolic impairment. We conducted 24-hour (h) metabolomic profiling every 4 h in 14 healthy adults (8 women) aged 26.4\u2009\u00b1\u20091.2\u2009years (mean\u2009\u00b1\u2009SD), undergoing a 6-day simulated night-shiftwork protocol. 24-h modeling analyses identified metabolite rhythms influenced by circadian versus behavioral cycles (sleep, food intake) and quantified internal circadian misalignment using acrophase shifts. Metabolic outcomes included glucose homeostasis (test meals) and energy expenditure (EE; whole-room calorimetry). Night-shiftwork produced widespread alterations in metabolite rhythms, with significant internal misalignment in multiple metabolites across pathways including pyrimidine metabolism, bile acid-microbiome signaling, and lipid metabolism. During misalignment, glucose and insulin area under the curve increased (p\u2009<\u20090.05) and EE decreased (p\u2009<\u20090.05). Internal misalignment of uridine and glycoursodeoxycholic acid was associated (p\u2009<\u20090.05) with impaired glucose tolerance, while their circulating concentrations were associated with decreased EE. Misalignment of uridine and glycoursodeoxycholic acid suggests dysregulated pyrimidine and bile acid-microbiome pathways as potential mechanisms linking circadian misalignment to cardiometabolic disease risk.\n\nID: 42437524\nTitle: Self-Assembled Wheat Gluten Peptide Nanoparticles as Dual-Functional Stabilizers for the Protection of Omega-3 Polyunsaturated Fatty Acids.\nAbstract: Omega-3 polyunsaturated fatty acids are highly susceptible to oxidation, limiting the shelf life and sensory quality of omega-3-fortified foods. Herein, wheat gluten peptide nanoparticles (WGPNs) with coupled emulsifying and antioxidant functions were produced by sequential pepsin-trypsin hydrolysis. LC-MS/MS showed a peptide pool (1-4 kDa) enriched in Gln/Pro, featuring hydrophobic motifs and C-terminal Lys/Arg residues that confer surfactant-like behavior. WGPNs formed spontaneously in aqueous media, mainly driven by hydrophobic association and hydrogen bonding, with concentration-dependent \u03b2-sheet formation and a critical aggregation concentration of \u223c0.17 mg/mL. Above this threshold, WGPNs exhibited enhanced radical-scavenging activity and colloidal stability across a wide ionic-strength range. Interfacial measurements demonstrated rapid adsorption of WGPNs at the oil-water interface, reduced interfacial tension, and formation of a stable interfacial layer. Consequently, WGPNs effectively stabilized fish oil emulsions and markedly retarded lipid oxidation. This work establishes WGPNs as a clean-label, dual-function platform for protecting oxidation-sensitive lipids in food systems.\n\nID: 42429130\nTitle: The role of central regulators in lipid hydroperoxide-mediated muscle atrophy. Exploring mechanisms beyond ferroptosis.\nAbstract: The oxidation of lipids in biological systems generates lipid hydroperoxides, which are implicated in cellular dysfunction, such as arteriosclerosis and cognitive decline. Although multiple lipid species, including phospholipids, ceramides, triglycerides, and free fatty acids, are susceptible to oxidation, the specific lipid species that drive disease development remain poorly defined. Lipid oxidation is primarily initiated and propagated by reactive oxygen species (ROS). ROS are highly reactive molecules that participate in diverse and complex intracellular signaling pathways. Ferroptosis is a recently identified form of regulated, non-apoptotic cell death characterized by iron-dependent accumulation of lipid peroxides, especially the peroxidation of polyunsaturated fatty acids in cellular membranes, ultimately leading to loss of membrane integrity. Oxidized phospholipids are considered key execution factors in ferroptosis, suggesting an important role for lipid peroxidation in maintaining physiological homeostasis across multiple organs. Our group recently demonstrated that oxidized phospholipids could serve as a source of ROS, thereby promoting muscle atrophy. In the present review, we summarize emerging evidence that membrane lipids, particularly oxidation of phospholipids and polyunsaturated fatty acids, contribute to the generation and propagation of cellular ROS, ultimately facilitating muscle atrophy.\n\nID: 42429052\nTitle: Endocrine\u2011metabolic imbalance drives osteoarthritis: From whole\u2011joint pathobiology to precision therapy (Review).\nAbstract: Osteoarthritis (OA) is a chronic degenerative joint disease closely associated with aging and metabolic dysfunction, characterized by cartilage degeneration, synovial inflammation, aberrant subchondral bone remodeling, pain and progressive functional impairment. Beyond mechanical loading, accumulating evidence indicates that OA is increasingly recognized as a whole\u2011joint disorder shaped by the interplay between local tissue damage and systemic endocrine\u2011metabolic imbalance. Endocrine factors, including sex hormones, thyroid hormone, melatonin, parathyroid hormone and vitamin D, together with metabolic disturbances, such as obesity, insulin resistance, dysregulated glucose and lipid metabolism and gut microbiota imbalances, can cooperatively remodel the joint microenvironment. Mechanistically, these alterations converge on immuno\u2011inflammatory amplification, mitochondrial dysfunction, oxidative stress, cellular senescence, metabolic reprogramming and regulated cell death, thereby promoting extracellular matrix degradation, persistent synovitis and uncoupled bone\u2011cartilage remodeling. The present review systematically summarizes the molecular basis of endocrine\u2011metabolic crosstalk in OA and discusses emerging therapeutic opportunities targeting hormonal signaling, metabolic pathways, circadian regulation, nutritional support and lifestyle interventions. Nevertheless, the reciprocal interactions among endocrine signals, systemic metabolic abnormalities and local joint pathology remain incompletely understood, and their translation into mechanism\u2011based clinical stratification remains at an early stage. Thus, targeting endocrine\u2011metabolic crosstalk may support mechanism\u2011based phenotyping and subtype\u2011informed precision therapy for OA, provided that candidate biomarkers and interventions are validated in prospective clinical studies.\n\nID: 42421941\nTitle: Macrophage-mediated nutrient recycling: evolutionary insights into the metabolic role of professional phagocytes.\nAbstract: Removal of senescent and damaged cells is fundamental for tissue homeostasis. While macrophage recognition and clearance of apoptotic cells are well characterized, the ultimate fate of the digested material remains poorly understood. Here, we explore current knowledge on the fate of engulfed material and examine how the metabolic nature of engulfed cargo shapes downstream signaling and phagocyte polarization. We also discuss emerging evidence that macrophages act as metabolic hubs, recycling and supplying nutrients to surrounding tissues. Drawing on studies in invertebrate phagocytes, we explore the evolutionary origins of this \"nurturing\" function and highlight its conservation in mammals, emphasizing its physiological relevance and potential contributions to metabolic disease.\n\nID: 42415079\nTitle: Genetic divergence in Aedes aegypti mosquitoes potentially associated with enhanced capacity for arbovirus transmission.\nAbstract: Aedes aegypti is the most important mosquito vector of arboviruses worldwide, originating on islands of the southwest Indian Ocean before spreading to Africa and, more recently, the Americas and Asia. Migration out of Africa was enabled by the evolution of behaviors that increased human-vector contact, and as Ae. aegypti became more domesticated, arboviral competence may have also increased. Here we investigate variation in vector competence between present-day populations of Ae. aegypti from Florida (USA) and Tanzania (East Africa) and use a genomics approach to examine genetic differentiation potentially underlying traits important for arbovirus transmission. Using vector-competence experiments with dengue virus serotype 2, we demonstrate greater susceptibility to infection in American mosquitoes, along with higher viral loads and a shorter time to virus dissemination. We then sought to identify highly divergent genes potentially underlying these differences and discovered more than 1.6 million single nucleotide polymorphisms via exome sequencing. Of these, 1058 were highly differentiated between populations (FST\u2009>\u20090.9) with more than half mapping to 17 outlier genes influencing chromatin remodeling, lipid metabolism, glycosylation, circadian rhythms, olfaction, and saliva bioactivity. Eight of these outlier genes formed a highly divergent genomic island on chromosome 2. Allele-frequency patterns of outlier genes across Ae. aegypti's range highlight genetic differentiation within sub-Saharan Africa, as well as evolutionary changes accompanying the shift towards domestication in the Americas and Asia. This work offers insights into phenotypic variation and evolutionary divergence within Ae. aegypti, including naturally occurring genetic variants that may influence transmission-related characters.\n\nID: 42410773\nTitle: Associations between cardiometabolic index and sleep disorders: Results from NHANES 2015 to 2020.\nAbstract: Sleep disorders have already been recognized as a public health concern, with evidence suggesting that lipid metabolism significantly affects sleep quality and circadian rhythms. Cardiometabolic index (CMI), a novel lipid index, has been confirmed to be associated with obesity-associated metabolic disorders, such as diabetes and cardiovascular disorders. Despite these findings, the exact relationship between CMI and sleep disorders remains to be fully validated. Consequently, our objective was to investigate the association between CMI and sleep disorders using data from the National Health and Nutrition Examination Survey (NHANES). Based on data from NHANES spanning 2015 to 2020, this study employed weighted multivariate logistic regression and restricted cubic spline (RCS) regression analysis to investigate the relationship between CMI and sleep disorders. Additionally, receiver operating characteristic analysis and the area under the curve were also utilized to assess the predictive performance of CMI for sleep disorders. Subgroup analyses and interaction tests were conducted to examine the consistency of this association across different populations. A positive association between CMI and sleep disorders was found in a cohort comprising 5817 participants aged 20 and above, which was further verified to be nonlinear through RCS regression analysis. Within the context of a fully adjusted model, when CMI was considered as a continuous variable, each one-unit increase was linked to a 17% increase in the prevalence of sleep disorders (odds ratio [OR]\u2005=\u20051.17; 95% CI: 1.06-1.29; P\u2005=\u2005.004). Upon stratifying CMI into quartiles, it was observed that participants in the highest quartile exhibited an 81% greater risk of developing sleep disorders compared to those in the lowest quartile (OR\u2005=\u20051.81; 95% confidence interval [CI]: 1.29-2.54; P\u2005=\u2005.002). Subgroup analyses and interaction tests demonstrated that the association between CMI and sleep disorders remained consistent across different subgroups, and no significant modification of this relationship was observed by other covariates except for body mass index. An elevated CMI is correlated with a higher probability of sleep disorders among individuals in the United States. Given the difficulty in establishing a causal relationship between the 2, further extensive prospective studies are necessary to investigate the role of CMI in the development of sleep disorders.\n\nID: 42386554\nTitle: Formation of Conjugated Polyenes, Malondialdehyde and Methylglyoxal in French Fries Produced with Four Different Types of Oils.\nAbstract: Lipid peroxidation products in French fries are a potential risk factor for non-communicable diseases. Malondialdehyde and methylglyoxal are among the most pathophysiologically-relevant lipid peroxidation products, but are generally not regarded as major products of the oxidation of linoleic acid- or monounsaturated fatty acid (MUFA)-rich oils, because mechanisms of their formation from such fatty acids are poorly understood. This study aimed to determine the formation of malondialdehyde and methylglyoxal, as well as conjugated dienes and conjugated trienes (precursors of secondary products including aldehydes) in French fries fried with four oils having different fatty acid composition. Conjugated dienes and trienes (CDs and CTs, respectively) were determined spectrophotometrically, malondialdehyde by the thiobarbituric acid test, and methylglyoxal by high performance liquid chromatography (HPLC). CT formation occurred to the same extent in sunflower and canola oils although the former lacked fatty acids with at least three double bonds, signifying desaturation of fatty acids during lipid peroxidation. More malondialdehyde was formed in sunflower oil containing more linoleic acid than canola oil with higher \u03b1-linolenic acid (18:3, n-3) content, indicating the importance of linoleic acid as a malondialdehyde precursor. Olive oil generated more malondialdehyde, methylglyoxal, CD and CT than palm olein, which is attributable to greater monounsaturated fatty acid content in the former. Mechanisms are proposed for the formation of CDs, CTs, malondialdehyde and methylglyoxal from MUFA and linoleic acid. Thus, MUFA- and linoleic acid-rich oils are relevant as sources of the two dialdehydes in fried foods. CDs and CTs can be considered as appropriate for monitoring lipid peroxidation even in MUFA- or linoleic acid-rich oils. Furthermore, formation of CDs through fatty acid desaturation helps to explain the formation of some 'unexpected' lipid oxidation products.\n\nID: 42384709\nTitle: Pachymic acid alleviates circadian rhythm disorders in high-fat diet-induced obesity mice via the sphingolipid pathway.\nAbstract: Obesity caused by a high-fat diet (HFD) is known to disrupt metabolic homeostasis and circadian rhythms. Pachymic acid (PA), a bioactive triterpenoid, exhibits anti-inflammatory, antihyperglycemic, antihyperlipidemic, and sedative-hypnotic properties, though its role in circadian regulation remains unexplored. We assessed PA's impact on metabolic dysfunction (glucose/lipid profiles), systemic inflammation using biochemical assays, ELISA, Oil Red O staining. Circadian parameters were evaluated via 24-h serum melatonin and core body temperature. Hepatic circadian gene oscillations and mechanistic pathways were analyzed through time-series RNA sequencing, bioinformatics, qPCR, and Western blotting. PA intervention attenuated obesity-related phenotypes, including reduced body weight, improved glucose/lipid metabolism, and restored physiological rhythms of melatonin and body temperature. And hepatic gene oscillation patterns were realigned to circadian synchrony. Mechanistically, PA ameliorated liver inflammation by modulating the sphingolipid pathway, specifically via S1PR4/TRAF2 signaling. Our findings illustrate PA's role in mitigating metabolic and circadian disruptions in obesity, highlighting the sphingolipid pathway as a tissue-specific target for circadian modulation. This study provides novel insights into therapeutic strategies for obesity-associated circadian disorders.\n\nID: 42361498\nTitle: Mallotus japonicus leaf extract restores TRPM6 magnesium channel expression and suppresses cellular senescence in colonic epithelial cells.\nAbstract: Age-related alterations in intracellular Mg2+ homeostasis can influence cellular bioenergetics and stress responses, yet the epithelial mechanisms linking aging and cellular senescence to impaired magnesium handling remain incompletely defined. Frailty is an emerging public health challenge in aging societies, and age-related magnesium deficiency has been proposed as one contributing factor. We investigated whether aging and cellular senescence impair epithelial magnesium handling in the colon and whether Mallotus japonicus (M. japonicus) leaf extract ameliorates these alterations in mouse colonic epithelial MCE301\u202fcells under senescence-inducing conditions. The mRNA levels of transient receptor potential melastatin 6 (TRPM6) magnesium channel were decreased in the intestines of middle-aged mice and in MCE301\u202fcells after long-term culture or tenovin-6-induced senescence. TRPM6 knockdown, tenovin-6, an inducer of cellular senescence, and low-Mg2+ medium each lowered intracellular free Mg2+ concentration ([Mg2+]i). Low-Mg2+ medium also attenuated proliferation. Transcriptome profiling suggested mitochondrial involvement under Mg2+-limiting conditions, consistent with reduced mitochondrial membrane potential and ATP production as well as increased mitochondrial fragmentation. M. japonicus leaf extract restored TRPM6 expression and [Mg2+]i, improved mitochondrial function, and suppressed senescence-associated secretory phenotype-related gene expression. Among the tested components of M. japonicus leaf extract, geraniin showed the strongest activity and also reduced senescence-associated \u03b2-galactosidase-positive cells, whereas corilagin, mallotinic acid, and mallotusinic acid showed partial effects. We suggest that aging- and senescence-associated TRPM6 downregulation is linked to impaired magnesium homeostasis and mitochondrial dysfunction in colonic epithelial cells. M. japonicus leaf extract and selected ellagitannin-related polyphenols mitigate these senescence-associated alterations.\n\nID: 42360622\nTitle: Overview of Novel Mechanisms in Obesity Pharmacotherapy and Implications for Cardiovascular Disease: A Narrative Review.\nAbstract: While nutrient-stimulated hormone (NuSH) therapies (e.g., glucagon-like pepide-1 receptor agonists and dual/triple agonists) have transformed the landscape of obesity pharmacotherapy, the next generation of medications may target body composition optimization or other cardiovascular benefits. This review examines novel obesity mechanisms outside of the NuSH class. Unique mechanisms for obesity treatment include peripherally restricted cannabinoid-1 receptor antagonism, myostatin/activin inhibitors, selective androgen receptor modulators, melanocortin-4 receptor agonism, mitochondrial modulation, thyroid receptor agonists, and fibroblast growth factor analogues. By targeting fat distribution, muscle preservation, inflammatory/oxidative stress pathways, lipid metabolism, and energy expenditure, these agents may improve both the magnitude and quality of weight loss. Early evidence suggests complementary roles alongside NuSH-based therapies for induction, augmentation, and maintenance strategies. Several non-NuSH agents have demonstrated potential in preclinical and early clinical studies to optimize body composition, but additional studies are required to prove large-scale, long-term safety and efficacy.\n\nID: 42359775\nTitle: Blue light exposure exacerbates Western diet-induced hepatic lipid accumulation and injury via suppression of the SIRT1-NR1D1 axis.\nAbstract: Excessive exposure to artificial blue light has been associated with circadian disruption and metabolic disorders; however, its role in hepatic lipid metabolism under dietary stress remains poorly defined. This study investigated how blue light exposure modulates Western diet-induced nonalcoholic fatty liver disease (NAFLD) and the underlying molecular mechanisms involving the NR1D1-SIRT1 metabolic axis. Male C57BL/6J mice were fed either a control or Western diet and exposed to blue light or sham illumination for 12 weeks. Hepatic morphology was evaluated by hematoxylin-eosin and Masson's trichrome staining, whereas macrophage infiltration and expression of NR1D1 and SIRT1 were assessed by immunohistochemistry. Untargeted LC-TOFMS-based metabolomic profiling and pathway enrichment analysis were conducted to characterize global metabolic alterations across experimental groups. The results showed that blue light exposure markedly aggravated Western diet-induced hepatic steatosis, ballooning, and lobular inflammation without evidence of fibrosis. Immunohistochemical staining revealed increased F4/80 positive macrophages and downregulation of NR1D1 and SIRT1 in blue light exposed, Western diet-fed (WDBL) mice, suggesting impaired mitochondrial homeostasis. Metabolomic profiling identified 113 hepatic metabolites, revealing distinct clustering by diet and light exposure. Blue light synergistically amplified Western diet-driven accumulation of long-chain and unsaturated acylcarnitines and polyunsaturated fatty acids, indicative of incomplete \u03b2-oxidation and oxidative lipid remodeling. Pathway enrichment analysis highlighted disruptions in glycerophospholipid, sphingolipid and bile acid metabolism, accompanied by reduced antioxidant cofactors (retinol and tocopherols). In conclusion, chronic blue light exposure accelerates Western diet-induced NAFLD progression by suppressing the SIRT1-NR1D1 axis, disrupting mitochondrial lipid oxidation, and promoting redox imbalance and macrophage-mediated inflammation. These findings identify environmental blue light as a metabolic stressor that synergizes with dietary lipid overload to drive hepatic injury, offering new mechanistic insight into light-associated metabolic liver disease.\n\nID: 42356241\nTitle: Dietary \u03b1-Tocopherol Deficiency Disrupts Hepatic Circadian Clock and Lipid Metabolism in Association with Gut Microbiota Dysbiosis.\nAbstract: Background/Objectives As a fat-soluble vitamin, vitamin E (VE) is prone to suboptimal intake in the general population. Alpha-tocopherol (\u03b1-TE) represents the most biologically significant form of VE in vivo. Nevertheless, the potential detrimental effects of \u03b1-TE deficiency on health remain unclear. This study was conducted to investigate the effect of \u03b1-TE deficiency on hepatic metabolism and gut microbiota. Methods C57BL/6J mice were randomly assigned to receive one of three dietary regimens: a \u03b1-TE-deficient diet, a control diet with normal \u03b1-TE, or a high-dose diet containing four times the normal \u03b1-TE level. Histopathology, serum biochemistry, RNA-Seq, RT-qPCR, Western blot, and 16S rRNA gene sequencing with correlation analysis were used to assess metabolic phenotypes, hepatic circadian, hepatic lipid metabolism, and cecal microbiota, respectively. Results The results demonstrated that \u03b1-TE deficiency induced hepatic steatosis and lipid metabolic disturbances. \u03b1-TE deficiency significantly decreased Arntl and Clock expression, but increased Per2. Additionally, it upregulated the expression of lipogenic genes such as Scd1, Elovl6, and Elovl3 and simultaneously downregulated fatty acid oxidation genes such as Cyp4a10, Cyp4a14, and Acot1, bringing about imbalance in lipid homeostasis. In addition, \u03b1-TE deficiency greatly changed the structure and composition of gut microbiota. Bacterial genera like Alistipes, norank_f__Muribaculaceae, Muribaculum, Odoribacter, and Dubosiella were significantly correlated with hepatic circadian and lipid metabolism gene expression with the strongest correlation being Alistipes. Conclusions This work is the first to reveal that short term \u03b1-TE deficiency could cause lipid metabolic disorder via the \"gut microbiota-liver circadian clock\" axis, which provides novel insights into the etiology of nutrition-related metabolic diseases and targets for nutritional intervention.\n\nID: 42353402\nTitle: Dietary Encapsulated Olive-Derived Polyphenols: Productive Performance and Meat Quality in Podolian Young Bulls.\nAbstract: This study evaluated the effects of dietary supplementation with nano- and micro-encapsulated polyphenol extract (PE) from olive leaves (OL) and olive mill wastewater (OMWW), respectively, on growth, carcass and meat quality traits in Podolian young bulls. Fifteen 12-month-old bulls were assigned to three groups: C (control); T1 (40 g/day nano-encapsulated PE from OL); and T2 (400 g/day olive leaf pellets plus 30 g/day micro-encapsulated PE from OMWW) for 40 days. Final body weight and carcass yield were unaffected, although the average daily gain was higher in T2 (p < 0.05). Meat from T2 exhibited lower moisture and higher protein content (p < 0.01) compared with the other groups. T1 showed higher \u03b1-tocopherol levels (p < 0.05). Lipid oxidation was reduced in both treated groups (p < 0.01). Monounsaturated fatty acids tended to decrease in treated groups (p = 0.057), while saturated and polyunsaturated fatty acids (PUFA) were unaffected. However, T2 showed higher total n-3 PUFA (p < 0.05), and a more favourable n-6/n-3 ratio (p < 0.01) was found in treated groups. These results highlight the potential of olive-derived polyphenols as functional feed ingredients to enhance meat quality and promote sustainable, circular livestock systems.\n\nID: 42346755\nTitle: Time-Dependent Endurance Exercise Improves Metabolic Health Through Circadian Rhythm Regulation in Mice.\nAbstract: Objectives: Circadian rhythms regulate key physiological processes, including metabolism and energy balance. Emerging evidence suggests that the timing of physical activity may influence metabolic outcomes. However, how the timing of endurance exercise impacts long-term metabolic health and the role of the circadian clock in this process remain unclear. This study aimed to investigate whether time-dependent endurance exercise improves metabolic health via circadian rhythm regulation. Methods: A 12-week endurance exercise protocol was established using wild-type (WT) and circadian-disrupted Clock\u039419 mice. Mice were assigned to exercise at Zeitgeber time 0 (ZT0) or Zeitgeber time 0 (ZT12), or to sedentary controls. Assessments included rotarod fatigue test, body weight, epididymal fat ratio, fasting blood glucose, serum triglycerides, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), non-esterified fatty acids (NEFA), intraperitoneal glucose tolerance test (IPGTT), and insulin tolerance test (ITT). Results: Clock\u039419 mice exhibited circadian phase-dependent fatigue susceptibility on the rotarod, particularly at ZT0. Both exercised Clock\u039419 groups (ZT0 and ZT12) showed significant weight reduction compared to sedentary controls, indicating that endurance exercise may counteracts circadian disruption-induced weight gain independent of timing. In WT mice, evening exercise (ZT12) led to enhanced lipid regulation and better glucose tolerance. These time-dependent benefits were absent in Clock\u039419 mutants, demonstrating that the full metabolic advantages of exercise require a functional circadian clock. Notably, endurance training also partially restored serum HDL-C levels in Clock\u039419 mice, suggesting compensatory metabolic responses. Conclusions: Aligning endurance exercise with the body's internal clock provides greater metabolic benefits than untimed exercise. The circadian clock is essential for time-dependent improvements in glucose and lipid metabolism, although some beneficial effects occur independently of a functional clock.\n\nID: 42340744\nTitle: Advanced molecular mechanisms underlying the anti-aging effects of Ipomoea batatas L. (sweet potato) leaves: bioactive compounds, cellular pathways, and functional food applications.\nAbstract: The global increase in life expectancy has intensified the need for effective dietary strategies to modulate biological aging and mitigate age-associated functional decline. Plant-derived bioactives have emerged as key regulators of aging-related molecular pathways; however, the anti-aging potential of sweet potato (Ipomoea batatas L. Lam.) leaves (SPL), a nutrient-dense yet underutilized leafy vegetable, remains insufficiently studied. This review aims to systematically evaluate the phytochemical composition, biological activities, and molecular mechanisms through which SPL bioactives influence the major hallmarks of aging. To our knowledge, this is the first comprehensive synthesis specifically focusing on the anti-aging mechanisms of SPL. Evidence from in vitro, in vivo, and emerging human studies demonstrates that SPL bioactives exert multi-targeted effects on oxidative stress, chronic inflammation, mitochondrial dysfunction, protein glycation, and cellular senescence. Mechanistically, SPL polyphenols activate the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway to enhance endogenous antioxidant defenses, while suppressing nuclear factor kappa B (NF-\u03baB)-mediated inflammatory signaling. Additional pathways include inhibition of advanced glycation end-product formation, AMP-Activated Protein Kinase (AMPK)-mediated mitochondrial biogenesis, preservation of telomere integrity, and protection of extracellular matrix homeostasis through modulation of matrix metalloproteinases and collagen synthesis. Collectively, these findings position SPL as a promising functional food candidate for healthy aging. However, clinical validation remains limited. Future research should prioritize randomized controlled trials, dose-response and bioavailability studies, and integrative omics-based approaches to confirm efficacy and facilitate translation into evidence-based functional food applications. Sweet potato leaves (SPL) contain polyphenols with potent anti-aging activity.SPL bioactives activate Nrf2 and suppress NF-\u03baB signaling pathways.SPL compounds regulate oxidative stress and cellular senescence.SPL bioactives promote AMPK-mediated mitochondrial protection.Preclinical studies support metabolic, vascular, and dermal benefits.\n\nID: 42334420\nTitle: Bile acid retention in efferocytic macrophages shapes their inflammatory status during cholangitis.\nAbstract: The clearance of apoptotic cells by phagocytes is crucial for restoring tissue balance after injury. In autoimmune liver diseases like primary sclerosing cholangitis, cell death is thought to result from accumulation of toxic bile acids within parenchymal cells. Whether, in this context, bile acid-loaded dying cells impact the efficiency of phagocytic macrophages in restoring tissue balance remains unknown. Here, we demonstrate that in a murine model of cholangitis, bile acids accumulate in a subpopulation of efferocytic macrophages with pro-inflammatory features. Our in vitro results indicate that, upon their engulfment, apoptotic hepatocytes laden with bile acids can serve as Trojan horses, delivering bile acids into efferocytic macrophages and thereby shaping macrophage function. This contrasts with the characteristics of macrophages that engulf apoptotic parenchymal cells lacking bile acids. Together, our findings delineate a system in which the content of the phagocytosed dying cells, specifically bile acid-laden hepatocytes, drives a pro-inflammatory program in the corresponding efferocytic macrophages, potentially contributing to chronic hepatic inflammation.\n\nID: 42329402\nTitle: Defective efferocytosis in diabetes: molecular mechanisms and emerging therapeutic strategies.\nAbstract: Diabetes is associated with oxidative stress, systemic immune dysregulation and chronic low-grade inflammation, which contributes to a wide spectrum of microvascular and macrovascular complications. Efferocytosis, the phagocytic clearance of apoptotic cells by macrophages and dendritic cells, is essential for inflammation resolution and tissue repair. Defective efferocytosis has been increasingly implicated in the progression of diabetes and several of its major complications, including atherosclerosis, nephropathy, retinopathy, impaired wound healing, and osteoporosis. This narrative review is prepared through a focused literature search of studies investigating efferocytosis in diabetes, elucidates how its disruption contributes to the progression of diabetic complications, and further highlight emerging therapeutic strategies aimed at regulating efferocytosis. This paper is expected to provide direction and outlook for the research on efferocytosis and diabetes. Efferocytosis regulation involves a coordinated cascade of find-me signals, engulfment receptors, intracellular cytoskeletal remodeling, and metabolic reprogramming. This review summarizes the key molecular changes of defective efferocytosis and pathological changes in diabetic complications. Importantly, emerging preclinical studies have demonstrated that restoring efferocytosis ameliorate inflammation, promote tissue regeneration, and interrupt the progression of diabetic complications. Efferocytosis not only illuminates fundamental aspects of immune regulation but also opens up new therapeutic possibilities. As the field continues to evolve, integrating efferocytosis-based interventions into the broader therapeutic landscape of diabetes may represent a paradigm shift in the management of its chronic complications.\n\nID: 42324635\nTitle: Effect of Dietary Polyphenols on PhIP Formation and Oxidative Reactions in Pan-Fried Chicken Patties.\nAbstract: Thermal processing of meat at elevated temperatures induces the generation of heterocyclic aromatic amines of food safety concern, among which 2-amino-1-methyl-6-phenylimidazo [4,5-b] pyridine (PhIP) predominates. This study explored the impact of five polyphenols (caffeic acid, curcumin, ellagic acid, quercetin, and resveratrol) added at 0.05%, 0.1%, and 0.2% (w/w) on oxidative reactions, precursor availability, PhIP formation, and quality characteristics of chicken meat cooked by pan-frying. Polyphenol incorporation significantly enhanced moisture retention and lowered cooking loss in the samples with quercetin added at 0.2%. Color analysis showed that most polyphenols increased lightness (L*) while curcumin significantly enhanced yellowness (b*). Redness (a*) decreased for all treatments except quercetin and caffeic acid. All polyphenols reduced the thermal consumption of PhIP precursors (glucose and creatine) with quercetin at 0.2% resulting in residual glucose and creatine levels of 0.83 and 2.08\u00a0mg/g, respectively. Quercetin showed the greatest reduction in lipid oxidation with TBARS inhibition up to 67.79% and the highest decrease in carbonyl content (43.63%). All polyphenols significantly suppressed PhIP formation with quercetin at 0.2% achieving the highest inhibition of PhIP (61.47%), followed by ellagic acid (53.65%), resveratrol (46.15%), and caffeic acid (45.46%) at the same concentration, while curcumin at 0.05% showed the weakest effect (10.25%). The radical scavenging activity of polyphenols did not strongly correlate with their ability to inhibit PhIP formation; correlation analysis revealed that PhIP inhibition was strongly correlated with the extent of lipid and protein oxidation. These findings suggest that dietary polyphenols can reduce PhIP formation in fried chicken patties.\n\nID: 42323492\nTitle: ERK1/2 activation in anti-inflammatory effects and underlying signaling mechanisms.\nAbstract: ERK1/2 are core components of the MAPK signaling pathway and play a central role in the regulation of inflammation. Although ERK1/2 activation is well established for driving pro-inflammatory responses, accumulating evidence systematically summarized in this review demonstrates that ERK1/2 activation can also exert potent anti-inflammatory and pro-resolving effects. At the cellular level, ERK1/2 activation mediates anti-inflammatory regulation through multiple coordinated mechanisms: It promotes activation-induced cell death in T cells, drives macrophages and microglia toward anti-inflammatory phenotypes while fine-tuning their phagocytic activity, enhances efferocytosis of apoptotic cells by myeloid cells to drive inflammation resolution, inhibits dendritic cell maturation, and induces production of the key anti-inflammatory cytokine IL-10. At the molecular signaling pathway level, ERK1/2 suppresses pro-inflammatory NF-\u03baB activity by stabilizing I\u03baB\u03b1, directly interacting with NF-\u03baB p65 subunit, or activating PPAR\u03b3 in both immune cells and tissue-resident cells. In addition, ERK1/2 exerts anti-inflammatory effects through the Nrf2/HO-1 axis, which negatively regulates NF-\u03baB. Further anti-inflammatory axes include the ERK1/2/CREB pathway and the FPR2/ERK1/2 pro-resolving signaling cascade. Other anti-inflammatory mechanisms include the ERK1/2/sCD14 axis that neutralizes LPS, ERK1/2-induced autophagy, and anti-inflammatory signaling triggered by diverse upstream regulators of ERK1/2. This review systematically consolidates the anti-inflammatory and pro-resolving effects of ERK1/2 activation and the underlying molecular mechanisms involved. These findings provide robust evidence that ERK1/2 activation can promote anti-inflammatory and inflammation-resolving responses and refine our understanding of the dual role of ERK1/2 as a \"double-edged sword\" in the regulation of inflammation.\n\nID: 42321866\nTitle: Gut microbiota-associated leucine elevation promotes cold-induced atherosclerotic plaque formation and instability.\nAbstract: Environmental factors such as cold exposure have been increasingly recognized as contributors to atherosclerosis progression, yet the underlying mechanisms linking environmental stress to vascular pathology remain incompletely understood. In particular, the role of the gut microbiota and microbiota-associated metabolites in cold-induced atherosclerosis has not been fully elucidated. A cold exposure model was established in ApoE\u207b/\u207b mice fed a Western diet. Integrated multi-omics analyses were combined with fecal microbiota transplantation (FMT) and mechanistic cellular assays to investigate gut microbiota remodeling, metabolic alterations, and immune regulation during cold-induced atherosclerosis. In this study, we demonstrate that cold exposure accelerates atherosclerotic plaque growth and instability in parallel with pronounced gut microbiota dysbiosis and alterations in host metabolic profiles. FMT combined with metabolomic analyses showed that cold-associated gut microbiota is closely associated with elevated circulating leucine levels, suggesting that cold-induced microbial remodeling may participate in this process by modulating host systemic leucine availability. Mechanistically, increased leucine suppressed the Zic family member 2 (Zic2) in macrophages, leading to reduced expression of growth arrest-specific 6 (Gas6), a key mediator of efferocytosis. Impaired Gas6-dependent efferocytosis resulted in defective clearance of apoptotic cells, heightened vascular inflammation, and increased plaque instability. Importantly, supplementation with Lactobacillus johnsonii, a commensal bacterium depleted under cold exposure, normalized circulating leucine levels, restored Zic2-Gas6 signaling, enhanced macrophage efferocytosis, and attenuated atherosclerotic plaque progression. Conversely, leucine supplementation recapitulated the effects of cold exposure on plaque development and instability. Collectively, these findings identify a previously unrecognized cold-microbiota-leucine-Zic2-Gas6-efferocytosis axis that links environmental stress to atherosclerosis progression. Targeting gut microbial regulation of host systemic leucine levels, including L. johnsonii-based interventions, may represent a promising therapeutic strategy for preventing cold-induced atherosclerotic cardiovascular disease.\n\nID: 42317866\nTitle: Chrononutrition and cardiometabolic health: circadian timing as a dimension of precision nutrition.\nAbstract: Cardiometabolic diseases, including obesity, type 2 diabetes mellitus (T2DM), hypertension, and cardiovascular disease (CVD), remain major global health challenges despite widespread adoption of evidence-based dietary guidelines. Traditional nutrition recommendations have largely focused on dietary composition and energy intake, with limited consideration of the timing of food consumption. Growing evidence indicates that metabolic processes are strongly regulated by circadian rhythms, suggesting that when food is consumed may be a critical but underappreciated determinant of cardiometabolic health. Chrononutrition, which examines the interaction between meal timing and the circadian system, has therefore emerged as an important area of research. This narrative review synthesizes human evidence linking chrononutrition to cardiometabolic outcomes, with a focus on obesity, insulin resistance and T2DM, lipid metabolism, and cardiovascular risk. Findings from observational studies, randomized clinical trials, and mechanistic investigations consistently demonstrate that eating later in the biological day or night is associated with impaired postprandial glucose regulation, reduced insulin sensitivity, altered lipid handling, and adverse cardiometabolic profiles, independent of dietary composition and total energy intake. In contrast, eating patterns aligned with endogenous circadian rhythms characterized by earlier energy intake and avoidance of late-night eating appear metabolically favorable. This review further situates chrononutrition within the framework of precision nutrition. While precision nutrition aims to explain interindividual variability in metabolic responses using genetic, metabolic, and microbiome-based approaches, circadian timing is rarely considered. Because metabolic capacity varies across the day-night cycle, failure to account for meal timing, chronotype, and circadian alignment may contribute to unexplained variability in dietary responses. Integrating chrononutrition into precision nutrition frameworks may therefore improve interpretation of metabolic phenotypes and enhance the personalization of dietary strategies. Finally, key research gaps are identified, highlighting the need for long-term, diverse human studies and time-resolved metabolic phenotyping to clarify the role of chrononutrition in cardiometabolic disease prevention.\n\nID: 42316289\nTitle: Human adipose-derived mesenchymal stem cells ameliorate Diabetic Kidney Disease by restoring macrophage efferocytosis.\nAbstract: Diabetic Kidney Disease (DKD) is a major complication driven by chronic inflammation and impaired tissue homeostasis. While mesenchymal stem cells (MSCs) show promise, the precise mechanisms by which human adipose-derived MSCs (hASCs) modulate macrophage-mediated resolution of inflammation remain to be fully elucidated. We integrated single-cell RNA sequencing (scRNA-seq) analysis of human DKD kidneys with in vivo evaluations in db/db mice and in vitro co-culture models. We employed transcriptomic and molecular approaches to systematically investigate how hASCs impact macrophage functional states. scRNA-seq revealed a significant dysregulation of phagocytosis and efferocytosis pathways in human DKD macrophages. In vivo, hASCs effectively homed to injured kidneys, improved renal filtration, and attenuated pathological injury. Rather than a simple binary pro-inflammation to anti-inflammatory switch, hASC treatment restored a comprehensive efferocytic program involving multiple functional stages: chemotaxis (GPR132), recognition/engulfment (PARP9, ELMO1, RAC1), and lysosomal digestion/exhaution and polarisation (LAMP1, LIPA, PPAR-\u03b3, ABCA1). This multi-targeted enhancement was accompanied contributed to the efficient clearance of apoptotic cells, reduced renal oxidative stress, and the mitigation of chronic inflammation. Our study systematically delineates the therapeutic benefits of hASCs, suggesting the promotion of macrophage efferocytosis as a significant mechanistic pathway by which hASCs exert their therapeutic effects. Specifically, we demonstrate that hASCs positively regulate key molecular signatures across multiple stages of this process - from \"find-me\" signal (LPC/GPR132) and \"eat-me\" recognition (PS/ELMO1) to lysosomal digestion (LAMP1) and subsequent exhaustion and polarisation (LIPA/PPAR-\u03b3/ABCA1).\n\nID: 42308879\nTitle: Metabolic impact of exercise timing: Myonectin dynamics in overweight and obese postmenopausal women following high-intensity interval training.\nAbstract: Myonectin is a myokine that regulates lipid metabolism, and levels are often reduced in obesity and insulin resistance. This study examined whether the timing of exercise influences myonectin and metabolic responses to high-intensity interval training in obese postmenopausal women. Fifty-eight sedentary postmenopausal women (body mass index 28-35\u00a0kg/m2) were randomized to high-intensity interval training or a control condition. The exercise group completed two counterbalanced cycling sessions (morning 08:00\u00a0h, evening 18:00\u00a0h). Blood samples were collected at baseline, immediately post-exercise, and 2\u00a0h post-exercise to measure serum myonectin, free fatty acids, glycerol, cortisol, and lipid profiles. High-intensity interval training significantly increased serum myonectin 2\u00a0h post-exercise in both morning and evening sessions (p\u00a0\u2264\u00a00.01). Free fatty acids and glycerol increased (p\u00a0\u2264\u00a00.01), and triglycerides decreased (evening: -4.8%, p\u00a0\u2264\u00a00.01). Evening exercise produced a lower peak heart rate (p\u00a0=\u00a00.042) and perceived exertion (p\u00a0=\u00a00.031) than morning exercise. No significant changes were observed in high-density lipoprotein, low-density lipoprotein, or total cholesterol. A single session of high-intensity interval exercise increased serum myonectin and lipolysis-related markers and reduced triglyceride concentrations in overweight and obese postmenopausal women. The higher 2-h myonectin value after evening exercise appears to reflect a time-specific variation rather than clear evidence of an overall evening-exercise advantage. Longitudinal studies using baseline-adjusted and mechanistic analyses are needed to determine whether acute timing-related differences translate into clinically meaningful adaptations.

In this study, we quantified a total of 749 plasma lipid species at baseline using liquid chromatography-mass spectrometry and performed cross-sectional and longitudinal association analysis of plasma lipidome profiles with longitudinal A/T/N biomarkers for AD in the Alzheimer's Disease Neuroimaging Initiative cohort (N\u2009=\u20091395). We identified several lipid species, classes, and network modules of correlated lipids that were significantly associated with cross-sectional and longitudinal changes of A/T/N biomarkers. Notably, we identified lysoalkylphosphatidylcholine (LPC(O)) as associated with cross-sectional \"A/N\" biomarkers at the lipid species, class, and module levels. Also, Phosphatidylethanolamine (PE) ethers were associated with A/T/N biomarkers in the species level and with \"N\" biomarkers in the class and module levels. GM3 ganglioside showed association with cross-sectional and longitudinal changes of \"N\" biomarkers at the species and class levels. Furthermore, 20 lipid species, out of all 57 species identified as associated with \"less severe\" AD biomarkers, contained docosahexaenoic acid (DHA), indicating that the previously reported beneficial effects of DHA on AD were significant at the central biomarker level. In conclusion, our approach linking peripheral metabolic changes with brain metabolic, structural, and functional states strengthens evidence from previous studies that were performed using only clinical AD diagnosis. Importantly, our study also enabled identification of novel lipids that play potential roles in progression of AD pathophysiology, suggesting dysregulation of lipid metabolic pathways as precursors to AD development and progression.\n\nID: 42302620\nTitle: Effects of chicken-liver-hydrolysate paste addition on structure-function relationships in emulsion-type sausages.\nAbstract: This study aimed to investigate the possible application on intergradation of chicken-liver-hydrolysate pastes (CLHPs) with meat products, which could enrich the utilization of CLHPs to meet the agrocycle principle. CLHPs rich in polyunsaturated and \u03c9-3 fatty-acid contents, were evaluated as sustainable raw-meat replacers in emulsion-type chicken sausages. Chicken breast was partially substituted with 0\u223c20% CLHPs. Increasing CLHP incorporation reduced viscoelasticity in raw meat batter as indicated by a decrease in storage modulus (G'), and altered water distribution in cooked meat batters, with LF-NMR T\u2082 relaxometry showing increased bound water and decreased free water. In cooked sausages, excessive CLHP addition (20%) destabilized the emulsion system, resulting in reduced cooking yield and water-holding capacity, together with elevated lipid oxidation (P < 0.05). Textural attributes were concurrently weakened at high substitution levels. CLHP inclusion altered color characteristics by decreasing lightness and increasing redness. Microstructural observations confirmed structural disruption and oil droplet coalescence at high inclusion levels. Overall, CLHP substitution should be limited to 15% to preserve emulsion stability and product quality. This research demonstrated that CLHPs are a novel value-added ingredient derived from broiler by-products. Their appropriate incorporation improved physicochemical properties in emulsified meat systems and provides practical guidance for partial meat replacement. These findings support the development of sustainable meat processing strategies and contribute to the valorization of poultry by-products within a circular food economy.\n\nID: 42300613\nTitle: Coordinated changes in microbiota features, short-chain fatty acids, and peripheral clocks accompany fructo-oligosaccharide-associated metabolic improvement.\nAbstract: Metabolic disorders induced by a high-fat diet (HFD) are closely linked to disruptions in the circadian regulation of glucose and lipid metabolism. This study evaluated the metabolic benefits and chrono-nutritional potential of the prebiotic fructo-oligosaccharides (FOS) in a mouse model of HFD-induced obesity using 24 hour time-series analysis. FOS supplementation not only reduced weight gain, insulin resistance, and hepatic steatosis, but also restored the diurnal oscillations of key metabolic genes (Srebp1c, Ppar\u03b1) and core circadian clock genes (Bmal1, Clock) in metabolic tissues. Notably, FOS reshaped gut microbiota composition by enriching beneficial genera and was accompanied by improved temporal organization of microbial metabolites, particularly the rhythmic production of short-chain fatty acids (SCFAs). Correlation analyses revealed strong temporal associations between FOS-induced microbial rhythmicity and improved host metabolic parameters. These findings suggest that FOS improves circadian metabolic homeostasis, accompanied by changes in gut microbiota rhythmicity and SCFAs rhythmicity, supporting its potential as a chrono-nutritional strategy in metabolic disorders.\n\nID: 42298408\nTitle: Low temperature-induced profiling of transcription and alternative splicing during seed germination in rice.\nAbstract: Low-temperature germination (LTG) is a critical agronomic trait for direct-seeded rice as it ensures uniform seedling establishment. Alternative splicing (AS), a key post-transcriptional mechanism, plays a crucial role in plant responses to abiotic stresses; however, the specific AS events and mechanisms involved in LTG remain poorly understood. In this study, we conducted RNA-Seq to profile the cold stress response in germinating seeds, and identified 12,558 differentially expressed genes (DEGs) in ZH11 seeds after 24\u00a0h of low\u2011temperature treatment during germination. GO annotation showed enrichment in genes associated with circadian rhythm, MAPK and plant hormone signaling, and metabolic processes including nitrogen metabolism. We also detected 12,494 cold-induced differential alternative splicing (DAS) events across 4,812 genes, primarily exon skipping (SE) and intron retention (RI). Cold-induced DAS genes were associated with lipid metabolism and terpenoid biosynthesis implying functions in metabolic adjustment and stress adaptation under cold stress. Furthermore, we identified several potential key regulators of LTG: genes OsCKLP2 and OsSTPK encoding protein kinase, OsPP2C11 encoding protein phosphatase, and transcription factors OsbHLH034, OsKNA2 and OsEREBP26. This study indicates that alternative splicing is involved in rice germination under cold stress. The findings not only advance the theoretical understanding of AS in LTG but also provide valuable genetic resources for breeding cold-tolerant rice.\n\nID: 42291617\nTitle: Replication of acne susceptibility loci and gene-environment interactions with screen time in Singapore and Malaysia Chinese population.\nAbstract: Acne vulgaris is a common chronic inflammatory skin disorder with a substantial genetic contribution. However, replication of findings from genome-wide association studies across diverse populations remains limited. In this study, we evaluated 88 previously reported acne-associated variants in 2741 acne cases and 2235 controls from the Singapore/Malaysia Cross-sequential Genetic Epidemiology Study. Two association signals were replicated at Bonferroni-corrected significance: rs1159268 near TGFB2 at 1q41 and rs738409 in the PNPLA3 coding region at 22q13.31, with consistent directions of effect. Functional annotation and transcriptomic evidence supported the involvement of these loci in pathways related to pilosebaceous unit biology, including epithelial differentiation, tissue homeostasis, retinoid regulation, and lipid metabolism. Gene-environment interaction analyses further identified 12 variants whose associations with acne risk were modified by screen-time exposure. These findings suggest that screen-associated exposures may act as contextual modifiers of genetic susceptibility, potentially through lifestyle-related metabolic factors, circadian endocrine regulation, and oxidative stress responses. Together, these findings emphasize the importance of considering environmental exposures alongside genetic susceptibility to refine our understanding of acne pathogenesis.\n\nID: 42290052\nTitle: [Mechanisms of Macrophage Efferocytosis-driven Remodeling of Lung Cancer \u2029Microenvironment Structure and Angiogenesis and Prospects for Clinical Intervention].\nAbstract: Lung cancer is one of the most prevalent and lethal malignant tumors worldwide. In recent years, immune checkpoint inhibitors have significantly improved the survival outcomes of some patients with advanced non-small cell lung cancer; however, primary and acquired resistance remain important barriers limiting their clinical efficacy. Research has revealed that structural remodeling of the tumor microenvironment (TME) is one of the key factors involved in immunotherapy resistance. Efferocytosis is an important process by which tumor-associated macrophages clear apoptotic cells. In the lung cancer TME, the high apoptotic cell burden can lead to persistent activation of efferocytosis. Studies have shown that sustained efferocytosis is not merely a process of cellular debris clearance, but can also induce metabolic reprogramming in macrophages, including dysregulated lipid metabolism and enhanced glycolysis, and promote the secretion of immunosuppressive and tissue-repair-related factors. These changes further promote pathological angiogenesis, activation of cancer-associated fibroblasts, and excessive extracellular matrix deposition, thereby driving structural remodeling of the TME and forming an immune-excluded microenvironment characterized by vascular abnormalities and stromal fibrosis. This process restricts effector T-cell infiltration and impairs the efficacy of immune checkpoint inhibitors. This review describes the molecular mechanisms of macrophage efferocytosis in the lung cancer TME, focusing on its regulatory roles in metabolic reprogramming, pathological angiogenesis, and stromal fibrosis, and discusses potential therapeutic strategies targeting efferocytosis-related signaling pathways and TME structural remodeling, aiming to provide new insights into overcoming immunotherapy resistance in lung cancer.\u2029. \u3010\u4e2d\u6587\u9898\u76ee\uff1a\u5de8\u566c\u7ec6\u80de\u80de\u846c\u9a71\u52a8\u80ba\u764c\u5fae\u73af\u5883\u7ed3\u6784\u91cd\u5851\u2029\u4e0e\u8840\u7ba1\u751f\u6210\u7684\u673a\u5236\u53ca\u4e34\u5e8a\u5e72\u9884\u524d\u666f\u3011 \u3010\u4e2d\u6587\u6458\u8981\uff1a\u80ba\u764c\u662f\u5168\u7403\u53d1\u75c5\u7387\u548c\u6b7b\u4ea1\u7387\u5747\u5c45\u9996\u4f4d\u7684\u6076\u6027\u80bf\u7624\u3002\u8fd1\u5e74\u6765\u514d\u75ab\u68c0\u67e5\u70b9\u6291\u5236\u5242\u663e\u8457\u6539\u5584\u4e86\u90e8\u5206\u665a\u671f\u975e\u5c0f\u7ec6\u80de\u80ba\u764c\u60a3\u8005\u7684\u751f\u5b58\u9884\u540e\uff0c\u4f46\u4ecd\u6709\u76f8\u5f53\u6bd4\u4f8b\u60a3\u8005\u5b58\u5728\u539f\u53d1\u6027\u6216\u7ee7\u53d1\u6027\u514d\u75ab\u8010\u836f\u3002\u80bf\u7624\u5fae\u73af\u5883\uff08tumor microenvironment, TME\uff09\u7ed3\u6784\u91cd\u5851\u88ab\u8ba4\u4e3a\u662f\u5f71\u54cd\u514d\u75ab\u6cbb\u7597\u7597\u6548\u7684\u91cd\u8981\u56e0\u7d20\u3002\u80de\u846c\u662f\u80bf\u7624\u76f8\u5173\u5de8\u566c\u7ec6\u80de\uff08tumor-associated macrophages, TAMs\uff09\u6e05\u9664\u51cb\u4ea1\u7ec6\u80de\u7684\u91cd\u8981\u8fc7\u7a0b\uff0c\u5728\u7ef4\u6301\u708e\u75c7\u6d88\u9000\u548c\u7ec4\u7ec7\u7a33\u6001\u7684\u540c\u65f6\uff0c\u53ef\u8bf1\u5bfc\u5de8\u566c\u7ec6\u80de\u53d1\u751f\u663e\u8457\u7684\u4ee3\u8c22\u91cd\u7f16\u7a0b\u53ca\u5206\u6ccc\u8c31\u6539\u53d8\u3002\u6301\u7eed\u6d3b\u5316\u7684\u80de\u846c\u4f5c\u7528\u901a\u8fc7\u8c03\u63a7\u8102\u8d28\u4ee3\u8c22\u548c\u7cd6\u9175\u89e3\u7b49\u4ee3\u8c22\u9014\u5f84\uff0c\u4fc3\u8fdb\u591a\u79cd\u514d\u75ab\u6291\u5236\u53ca\u7ec4\u7ec7\u4fee\u590d\u56e0\u5b50\u7684\u5206\u6ccc\uff0c\u4ece\u800c\u9a71\u52a8\u5f02\u5e38\u8840\u7ba1\u751f\u6210\u3001\u6fc0\u6d3b\u80bf\u7624\u76f8\u5173\u6210\u7ea4\u7ef4\u7ec6\u80de\u5e76\u4fc3\u8fdb\u7ec6\u80de\u5916\u57fa\u8d28\u6c89\u79ef\uff0c\u5bfc\u81f4\u80bf\u7624\u57fa\u8d28\u7ed3\u6784\u91cd\u5851\uff0c\u5f62\u6210\u514d\u75ab\u6392\u65a5\u578bTME\uff0c\u9650\u5236\u6548\u5e94T\u7ec6\u80de\u6d78\u6da6\u5e76\u964d\u4f4e\u514d\u75ab\u6cbb\u7597\u7597\u6548\u3002\u672c\u6587\u7efc\u8ff0\u80de\u846c\u4f5c\u7528\u5728TME\u4e2d\u7684\u5206\u5b50\u673a\u5236\uff0c\u91cd\u70b9\u9610\u8ff0\u5176\u5728\u4ee3\u8c22\u91cd\u7f16\u7a0b\u3001\u8840\u7ba1\u751f\u6210\u5f02\u5e38\u53ca\u57fa\u8d28\u7ea4\u7ef4\u5316\u4e2d\u7684\u4f5c\u7528\uff0c\u5e76\u63a2\u8ba8\u9776\u5411\u80de\u846c\u76f8\u5173\u4fe1\u53f7\u901a\u8def\u53caTME\u7ed3\u6784\u91cd\u5851\u7684\u6f5c\u5728\u6cbb\u7597\u7b56\u7565\uff0c\u5e76\u8fdb\u4e00\u6b65\u63a2\u8ba8\u80de\u846c\u76f8\u5173\u6307\u6807\u5728\u514d\u75ab\u68c0\u67e5\u70b9\u6291\u5236\u5242\u7597\u6548\u9884\u6d4b\u7684\u6f5c\u5728\u4ef7\u503c\uff0c\u4ee5\u671f\u4e3a\u80ba\u764c\u514d\u75ab\u6cbb\u7597\u8010\u836f\u7684\u7cbe\u51c6\u5e72\u9884\u63d0\u4f9b\u65b0\u7684\u7814\u7a76\u601d\u8def\u3002\u2029\u3011 \u3010\u4e2d\u6587\u5173\u952e\u8bcd\uff1a\u80ba\u80bf\u7624\uff1b\u5de8\u566c\u7ec6\u80de\uff1b\u80de\u846c\uff1b\u80bf\u7624\u5fae\u73af\u5883\uff1b\u4ee3\u8c22\u91cd\u7f16\u7a0b\uff1b\u8840\u7ba1\u751f\u6210\u3011.\n\nID: 42289901\nTitle: p120-catenin enhances macrophage efferocytosis and facilitates resolution of lung inflammatory injury.\nAbstract: Defective resolution of inflammation following sepsis contributes to persistent immune dysfunction and increased morbidity and mortality worldwide. Efficient clearance of apoptotic polymorphonuclear neutrophils (PMNs) by macrophages, a process known as efferocytosis, is essential for resolving inflammation, promoting tissue repair, and restoring immune homeostasis; however, the molecular mechanisms governing this process remain poorly understood. Here, we identify p120-catenin (p120) as a critical regulator of efferocytosis that promotes the resolution of inflammatory lung injury. In alveolar macrophage-depleted mice challenged with endotoxin, intratracheal instillation of p120-deficient macrophages delayed the resolution of PMN infiltration, protein exudation, and lung edema and injury compared with control macrophages. These changes were accompanied by increased levels of TNF-\u03b1 and IL-6, decreased levels of TGF-\u03b2 and IL-10, and a reduced number of macrophages containing apoptotic PMNs in bronchoalveolar lavage fluid. p120 depletion also markedly reduced the phagocytosis of apoptotic PMNs by cultured macrophages. Mechanistically, p120 deficiency decreased the expression of the efferocytic receptors CD36 and Axl and shifted macrophage polarization toward a pro-inflammatory M1 phenotype. Furthermore, apoptotic cells induced the association and co-localization of p120 with peroxisome proliferator-activated receptor-\u03b3 (PPAR\u03b3), whereas p120 deletion markedly reduced PPAR\u03b3 activity in response to apoptotic PMNs. Pharmacologic inhibition of PPAR\u03b3 abolished p120-mediated macrophage efferocytosis and the resolution of lung inflammation. Collectively, these findings establish a central role for p120 in macrophage efferocytosis and inflammatory resolution and suggest that targeting macrophage p120 may represent a novel therapeutic strategy to promote recovery from inflammatory lung injury.\n\nID: 42288204\nTitle: Sleep and aging: The role of DNA methylation.\nAbstract: Although its evolutionary origins remain poorly understood, sleep is a highly conserved physiological process crucial to animal life and widely recognized as a major determinant of human healthspan. Sleep disturbances are a major public health concern, particularly among older adults, contributing to impaired cognitive function, chronic disease risk, and reduced quality of life. Age-related sleep disturbances are associated with epigenetic changes, especially altered DNA methylation patterns within genes and regulatory regions involved in circadian rhythms, neuroplasticity, metabolism, and inflammation. Over the past decade, epigenetic clocks, which measure DNA methylation patterns at specific CpG sites, have been used to estimate chronological age, assess biological aging, and predict health outcomes and mortality risk. Using epigenetic clocks and genome-wide methylation studies, emerging evidence has linked sleep disturbances and sleep-disrupting conditions, such as insomnia, obstructive sleep apnea, and shift work, to accelerated biological aging. Sleep-related changes in DNA methylation contribute to epigenetic age acceleration by influencing key aging processes, including inflammation, oxidative stress, telomere maintenance, lipid metabolism, and immune function. However, these methylation alterations might be, at least in part, reversible, highlighting opportunities to develop interventions that improve sleep disturbances and slow biological aging.\n\nID: 42287886\nTitle: The elevated clock genes involved in regulating the hormone secretion and follicular development during the laying period of geese.\nAbstract: The reproductive performance of geese is regulated by the hypothalamic-pituitary-ovarian (HPO) axis, which controls ovarian follicular development and hormone secretion, and ultimately determines egg production. In this study, Wanxi White geese at three reproductive stages (pre-laying, laying, and broody periods) were used to investigate the regulatory roles of circadian clock genes in follicular development. Results showed that follicular growth, serum levels of estradiol (E2), melatonin (MLT), and progesterone (P4) markedly increased during the laying period, whereas a higher number of atretic follicles was observed during the broody period. Correspondingly, expression of steroidogenesis-related genes (CYP11A1, CYP19A1, DHCR24, 3\u03b2-HSD and StAR) and melatonin synthesis-related gene (ASMT-1) was upregulated in the laying periods compared with pre-laying and broody periods. Moreover, expression of clock genes (CLOCK, PER2, CRY1, CRY2, ARNTL2A, EYA3 and NPAS2) was significantly higher in the hypothalamus during the laying period than that in the broody period. Notably, CLOCK, PER2, CRY1, CRY2 and DIO2 exhibited similar expression patterns in the hypothalamus and ovary across the three reproductive stages, suggesting that circadian clock genes may contribute to the coordination of hypothalamic and ovarian functions. In addition, genes involved in lipid metabolism and yolk precursor synthesis were markedly upregulated in both the liver and ovary during the laying period. Overall, the elevated expression of clock genes could play an important role in follicular development, hormone secretion, and the coordinating of hepatic lipid transport and yolk precursor formation, providing a theoretical basis for improving egg production and breeding strategies in Wanxi White geese.\n\nID: 42282667\nTitle: Mitochondrial carrier SLC25A34 links clock, diet, and temperature control of interorganellar lipid cycling.\nAbstract: Adipocyte lipid metabolism is coordinated by circadian rhythms, diet, and environmental temperature. Yet how these diverse signals are molecularly integrated remains unknown. Here we show that clock, diet, and temperature cues converge on the orphan mitochondrial transporter, SLC25A34, to orchestrate thermogenic cycling of lipid synthesis and oxidation. During sleep, the clock suppresses Slc25a34 transcription through REV-ERB\u03b1. Waking, lipid-rich diets, or cold exposure abolish this repression, allowing lipolytic signals to stimulate Slc25a34 expression via PPAR\u03b1. SLC25A34 then imports oxaloacetate into mitochondria to accelerate the export of substrates used for acetyl-CoA production in the cytosol. This feeds into cytosolic lipid synthesis and transcriptional induction of mitochondrial biogenesis, which collectively promote mitochondrial lipid oxidation. Thus, SLC25A34 confers circadian, dietary, and environmental control of thermogenic metabolism through interorganellar lipid cycling.\n\nID: 42282444\nTitle: Polygonati Rhizoma Attenuates Oxidative Stress-Induced Senescence in Periodontal Ligament Stem Cells.\nAbstract: Periodontitis is increasingly recognized as a non-communicable chronic oral disease in which sustained oxidative stress and cellular senescence drive low-grade inflammation and tissue destruction. Polygonati Rhizoma (PR), a traditional Chinese herb widely consumed as a functional food ingredient, is rich in antioxidant polyphenols and polysaccharides, yet its role in modulating senescence of periodontal ligament stem cells (PDLSCs) remains unclear. This study integrated network pharmacology and experimental validation to elucidate the protective effects and mechanisms of PR against oxidative stress-induced PDLSC senescence. Putative PR components and targets related to periodontitis and aging were collected to construct a protein-protein interaction (PPI) network, from which 21 core targets were predicted. These included key inflammation- and senescence-related proteins such as TP53, RELA (p65), TNF-\u03b1, TGF-\u03b21, IL-6, IL-1\u03b2, CXCL8, and MMP-9. Gene Ontology and KEGG enrichment analyses highlighted pathways involved in cellular senescence, NF-\u03baB signaling, and oxidative stress responses. Molecular docking suggested strong binding affinities between major PR constituents and putative core protein targets. In an in\u00a0vitro oxidative stress-induced PDLSC senescence model, PR-medicated serum, with Metformin as a positive control, significantly reduced intracellular oxidative stress markers, alleviated cell-cycle arrest, and downregulated senescence-associated secretory phenotype (SASP) cytokines. PR showed anti-senescent efficacy comparable to Metformin while exhibiting distinct molecular signatures. These findings indicate that PR exerts multi-component, multi-target modulation of NF-\u03baB-centered inflammatory and senescence pathways in PDLSCs, thereby mitigating oxidative stress-induced cellular aging. As an edible, functional herb, PR may represent a promising dietary adjunct for the prevention and management of periodontitis linked to cellular senescence.\n\nID: 42279736\nTitle: Alcalase-Flavourzyme Red Seaweed Hydrolysates as Antioxidants to Enhance Oxidative Stability of DHA Nanoemulsions.\nAbstract: This study evaluated Palmaria palmata hydrolysates produced using Alcalase\u00ae and Flavourzyme\u00ae at 1, 2, 3, 4, 5, and 10% (w/w biomass protein, corresponding to AF1-10), and their performance in oil-in-water nanoemulsions under iron-induced oxidation. AF4 showed significantly higher total amino acid and phenolic contents and the strongest Fe2+-chelating activity (IC50 = 1.64 \u00b1 0.22 mg/mL, p < 0.05) and was therefore selected for nanoemulsion stabilization. Nanoemulsions exhibited high physical stability with no significant changes in droplet sizes (D3,2 ~77-79 nm), \u03b6-potential (~-18 to -19 mV), and viscosity (~1.2-1.5 cP) (p > 0.05). Dynamic interfacial tension measurements and confocal laser scanning microscopy (CLSM) indicated limited interfacial activity of AF4, with most components remaining in aqueous phase. Compared to the control, AF4 significantly reduced peroxide formation (~100-164 vs. 289-357 meq/kg at Day 4-8, p < 0.05) and partially preserved tocopherols. It also delayed the formation of some volatiles during intermediate stages of storage. However, it was less effective than ethylenediaminetetraacetic acid (EDTA). Increasing the AF4 concentration did not further improve oxidative stability. These findings suggest that antioxidant efficacy depends on composition, interfacial behavior, and spatial distribution. Antioxidants with limited interfacial activity may therefore exhibit different modes of action within emulsified systems.\n\nID: 42277793\nTitle: Cel-LDH dual-functional nanotherapy simultaneously promotes microglial efferocytosis and alleviates neuronal apoptosis for spinal cord injury recovery.\nAbstract: Traumatic spinal cord injury (SCI) can cause severe central nervous system damage. Efferocytosis, an intrinsic regulatory mechanism through which microglia eliminate apoptotic cells, is suppressed because of the local ischaemic and hypoxic microenvironment after spinal cord injury (SCI). In addition, hypoxia and reoxygenation (H/R) trigger mitochondrial respiratory chain electron leakage, leading to the massive generation of mitochondrial reactive oxygen species (mtROS), impairing the energy supply and causing oxidative stress damage in neurons, which induces neuronal apoptosis. Synergistic therapies targeting efferocytosis and neuronal apoptosis are important for recovery after SCI. In this study, by loading celastrol in a layered double hydroxide, a multifunctional nanoparticle, Cel-LDH, was developed to facilitate SCI recovery by concurrently normalizing efferocytosis homeostasis and inhibiting neuronal apoptosis. Cel-LDH composite nanoparticles strongly scavenged ROS and preserved mitochondrial homeostasis, thus regulating apoptosis-related proteins, including Bax and Bcl-2, and effectively inhibiting the apoptotic process of neurons. Furthermore, Cel-LDH nanoparticles promoted autophagy, inhibited the cyclic GMP-AMP (cGAMP) synthase (cGAS)-stimulator of interferon genes (Sting) pathway to modulate the anti-inflammatory phenotypic transformation of microglia, and subsequently restored the efferocytosis homeostasis of microglia, thus suppressing inflammatory cascades and creating favourable microenvironments for the repair of SCI. This approach not only remodels the dysfunctional efferocytosis capacity but also inhibits neuronal apoptosis, providing a new therapeutic strategy for SCI.\n\nID: 42277229\nTitle: Plasma proteomics of sleep traits reveals systemic immune-metabolic pathways and genetically prioritized proteins.\nAbstract: The plasma proteomic signatures of sleep disturbance remain poorly characterized. Using data from 43,709 predominantly European-ancestry, middle-aged and older UK Biobank participants, we depict a large-scale atlas of plasma proteomic signatures of seven self-reported sleep traits (sleep duration, chronotype, insomnia symptoms, daytime napping, daytime sleepiness, snoring, and ease of getting up in the morning) and a derived sleep health score. We identify 935 proteins associated with at least one sleep trait, converging on lipid metabolism, immune function and inflammation, cell adhesion, and neurochemical signaling. Leveraging genomic structural equation modeling to define three latent sleep factors, namely circadian preference, daytime sleep burden, and nighttime sleep adequacy, bidirectional Mendelian randomization (MR) identifies one protein (LTA) with robust cis-instrument and strong colocalization support (PP.H4\u2009=\u20090.98) for a putative causal effect on nighttime sleep adequacy. Sixteen additional genetically supported candidate proteins rely primarily on trans-pQTL instruments or weaker colocalization. These genetically supported candidates are prospectively associated with incident cardiovascular disease, stroke, type 2 diabetes, dementia, chronic kidney disease, depression, and mortality over a median 13.6-year follow-up, with the strongest per-SD hazard ratio (HR) associations observed for chronic kidney disease (e.g., BTN2A1: HR\u2009=\u20092.33) and type 2 diabetes (e.g., RBP5: HR\u2009=\u20091.58). Collectively, these findings highlight the potential of large-scale proteomics in elucidating sleep pathogenesis, and generate testable hypotheses for validation in independent cohorts and experimental models.\n\nID: 42276708\nTitle: Measuring efferocytosis by intraperitoneal clearance assay.\nAbstract: Efferocytosis is a critical process by which phagocytes identify, engulf and clear apoptotic cells, thereby preserving immune tolerance and tissue homeostasis. While in vitro assays have advanced our understanding of the molecular mechanisms underlying apoptotic cell clearance, they lack the complexity of the physiological environment. This chapter presents a detailed in vivo approach for assessing efferocytosis by mouse peritoneal macrophages using the intraperitoneal (IP) clearance assay. By administering fluorescently labelled apoptotic Jurkat T cells into the peritoneal cavity, this method enables the quantification of apoptotic cell uptake in a native tissue context, capturing the influence of local immune signals, stromal interactions and systemic factors. This protocol is compatible with genetic and pharmacological manipulations, allowing researchers to investigate how various interventions affect efferocytic capacity. Overall, this approach provides a robust and physiologically relevant framework for studying efferocytosis and its implications in both homeostatic and pathological settings.\n\nID: 40564914\nTitle: Fecal Microbiota Transplantation from Mice Receiving Magnetic Mitohormesis Treatment Reverses High-Fat Diet-Induced Metabolic and Osteogenic Dysfunction.\nAbstract: This study compared the metabolic consequences of fecal microbiota transplantation (FMT) from donor mice that had been either administered pulsed electromagnetic field (PEMF) therapy or exercised to recipient mice fed a high-fat diet (HFD). Eight weeks of PEMF treatment (10 min/week) enhanced PGC-1\u03b1-associated mitochondrial and metabolic gene expression in white and brown adipose to a greater degree than eight weeks of exercise (30-40 min/week). FMT from PEMF-treated donor mice recapitulated these adipogenic adaptations in HFD-fed recipient mice more faithfully than FMT from exercised donors. Direct PEMF treatment altered hepatic phospholipid composition, reducing long-chain ceramides (C16:0) and increasing very long-chain ceramides (C24:0), which could be transferred to PEMF-FMT recipient mice. FMT from PEMF-treated mice was also more effective at recovering glucose tolerance than FMT from exercised mice. PEMF treatment also enhanced bone density in both donor and HFD recipient mice. The gut Firmicutes/Bacteroidetes (F/B) ratio was lowest in both the directly PEMF-exposed and PEMF-FMT recipient mouse groups, consistent with a leaner phenotype. PEMF treatment, either directly applied or via FMT, enhanced adipose thermogenesis, ceramide levels, bone density, hepatic lipids, F/B ratio, and inflammatory blood biomarkers more than exercise. PEMF therapy may represent a non-invasive and non-strenuous method to ameliorate metabolic disorders.\n\nID: 38989587\nTitle: Aging AdipoR2-deficient mice are hyperactive with enlarged brains excessively rich in saturated fatty acids.\nAbstract: To investigate how the fatty acid composition of brain phospholipids influences brain-specific processes, we leveraged the AdipoR2 (adiponectin receptor 2) knockout mouse model in which the brain is enlarged, and cellular membranes are excessively rich in saturated fatty acids. Lipidomics analysis of brains at 2, 7, and 18\u2009months of age showed that phosphatidylcholines, which make up about two-thirds of all cerebrum membrane lipids, contain a gross excess of saturated fatty acids in AdipoR2 knockout mice, and that this is mostly attributed to an excess palmitic acid (C16:0) at the expense of oleic acid (C18:1), consistent with a defect in fatty acid desaturation and elongation in the mutant. Specifically, there was a\u2009~12% increase in the overall saturated fatty acid content within phosphatidylcholines and a\u2009~30% increase in phosphatidylcholines containing two palmitic acids. Phosphatidylethanolamines, sphingomyelins, ceramides, lactosylceramides, and dihydroceramides also showed an excess of saturated fatty acids in the AdipoR2 knockout mice while nervonic acid (C24:1) was enriched at the expense of shorter saturated fatty acids in glyceroceramides. Similar defects were found in the cerebellum and myelin sheaths. Histology showed that cell density is lower in the cerebrum of AdipoR2 knockout mice, but electron microscopy did not detect reproducible defects in the ultrastructure of cerebrum neurons, though proteomics analysis showed an enrichment of electron transport chain proteins in the cerebellum. Behavioral tests showed that older (33\u2009weeks old) AdipoR2 knockout mice are hyperactive and anxious compared to control mice of a similar age. Also, in contrast to control mice, the AdipoR2 knockout mice do not gain weight in old age but do have normal lifespans. We conclude that an excess fatty acid saturation in brain phospholipids is accompanied by hyperactivity but seems otherwise well tolerated.\n\nID: 37052768\nTitle: Plasma metabolomic signatures of dual decline in memory and gait in older adults.\nAbstract: Older adults experiencing dual decline in memory and gait have greater dementia risk than those with memory or gait decline only, but mechanisms are unknown. Dual decline may indicate specific pathophysiological pathways to dementia which can be reflected by circulating metabolites. We compared longitudinal changes in plasma metabolite biomarkers of older adults with and without dual decline in the Baltimore Longitudinal Study of Aging (BLSA). Participants were grouped into 4 phenotypes based on annual rates of decline in verbal memory and gait speed: no decline in memory or gait, memory decline only, gait decline only, and dual decline. Repeated measures of plasma metabolomics were measured by biocrates p500 kit during the same time of memory and gait assessments. In BLSA, 18 metabolites differed across groups (q-value\u2009<\u20090.05). Metabolites differentially abundant were enriched for lysophosphatidylcholines (lysoPC C18:0,C16:0,C17:0,C18:1,C18:2), ceramides (d18:2/24:0,d16:1/24:0,d16:1/23:0), and amino acids (glycine) classes. Compared to no decline, the dual decline group showed greater declines in lysoPC C18:0, homoarginine synthesis, and the metabolite module containing mostly triglycerides, and showed a greater increase in indoleamine 2,3-dioxygenase (IDO) activity. Metabolites distinguishing dual decline and no decline groups were implicated in metabolic pathways of the aminoacyl-tRNA biosynthesis, valine, leucine and isoleucine biosynthesis, histidine metabolism, and sphingolipid metabolism. Older adults with dual decline exhibit the most extensive alterations in metabolic profiling of lysoPCs, ceramides, IDO activity, and homoarginine synthesis. Alterations in these metabolites may indicate mitochondrial dysfunction, compromised immunity, and elevated burden of cardiovascular and kidney pathology.\n\nID: 37050937\nTitle: Association Between Plasma Ceramides and One-Year Mortality in Patients with Acute Coronary Syndrome: Insight from the PEACP Study.\nAbstract: The plasma lipidome profile is likely to improve risk stratification in patients with acute coronary syndrome (ACS) and predict cardiovascular events for secondary disease prevention. Ceramides are involved in the initiation or acceleration of several key pathophysiological processes in atherosclerosis. This study evaluated whether plasma ceramide levels at admission was associated with one-year mortality in patients with ACS. In total, 826 patients with ACS from a prospective multicenter study for early evaluation of acute chest pain were enrolled. High-performance liquid chromatography with tandem mass spectrometry (LC/MS) was used to measure the plasma levels of eleven ceramides (C16-C26). The primary outcome was all-cause mortality, and the secondary outcome was cardiac mortality during the one-year follow-up. The relationship between the ceramide levels and mortality was evaluated by Cox regression analysis. The receiver operating characteristic (ROC) curve was established to evaluate discrimination of ceramides. Eighty-eight (10.7%) patients died after a 12-month follow-up. Five ceramides (C16:0, C18:0, C20:0, C24:1 and C24:2) and their ratios to Cer(d18:1/24:0) were independently associated with the risk of all-cause death and cardiac death. Combining the Global Registry of Acute Coronary Events (GRACE) score with ceramides and their ratios to Cer(d18:1/24:0) had areas under ROC curves ranging from 0.778-0.804 (P<0.001) for all-cause mortality, which was greater than that of the GRACE score alone. Measurements of long-chain ceramides and very-long-chain ceramides may help in identifying a high risk of mortality beyond traditional assessment tools in patients with ACS. clinicaltrials.gov, identifier: NCT04122573.\n\nID: 35358682\nTitle: Dietary lipid droplet structure in postnatal life improves hepatic energy and lipid metabolism in a mouse model for postnatal programming.\nAbstract: Early-life diets may have a long-lasting impact on metabolic health. This study tested the hypothesis that an early-life diet with large, phospholipid-coated lipid droplets (Concept) induces sustained improvements of hepatic mitochondrial function and metabolism. Young C57BL/6j mice were fed Concept or control (CTRL) diet from postnatal day 15 (PN15) to PN42, followed by western style (WSD) or standard rodent diet (AIN) until PN98. Measurements comprised body composition, insulin resistance (HOMA-IR), tricarboxylic acid (TCA) cycle- and \u03b2-oxidation-related hepatic oxidative capacity using high-resolution respirometry, mitochondrial dynamics, mediators of insulin resistance (diacylglycerols, DAG) or ceramides) in subcellular compartments as well as systemic oxidative stress. Concept feeding increased TCA cycle-related respiration by 33% and mitochondrial fusion protein-1 by 65% at PN42 (both p\u00a00.05). At PN98, CTRL, but not Concept, mice developed hyperinsulinemia (CTRL/AIN 0.22\u00a0\u00b1\u00a00.44 vs. CTRL/WSD 1.49\u00a0\u00b1\u00a00.53 nmol/l, p\u00a00.05 and Concept/AIN 0.20\u00a0\u00b1\u00a00.38 vs. Concept/WSD 1.00\u00a0\u00b1\u00a00.29 nmol/l, n.s.) and insulin resistance after WSD (CTRL/AIN 107\u00a0\u00b1\u00a023 vs. CTRL/WSD 738\u00a0\u00b1\u00a0284, p\u00a00.05 and Concept/AIN 109\u00a0\u00b1\u00a024 vs. Concept/WSD 524\u00a0\u00b1\u00a0157, n.s.). WSD-induced liver weight was 18% lower in adult Concept-fed mice and \u03b2-oxidation-related respiration was 69% higher (p\u00a00.05; Concept/WSD vs. Concept/AIN) along with lower plasma lipid peroxides (CTRL/AIN 4.85\u00a0\u00b1\u00a00.28 vs. CTRL/WSD 5.73\u00a0\u00b1\u00a00.47\u00a0\u00b5mol/l, p\u00a00.05 and Concept/AIN 4.49\u00a0\u00b1\u00a00.31 vs. Concept/WSD 4.42\u00a0\u00b1\u00a00.33\u00a0\u00b5mol/l, n.s.) and were in part protected from WSD-induced increase in hepatic cytosolic DAG C16:0/C18:1. Early-life feeding of Concept partly protected from WSD-induced insulin resistance and systemic oxidative stress, potentially via changes in specific DAG and mitochondrial function, highlighting the role of early life diets on metabolic health later in life.\n\nID: 34333058\nTitle: Association of plasma ceramides with prevalent and incident type 2 diabetes mellitus in middle and older aged adults.\nAbstract: The role of ceramides in the pathogenesis of type 2 diabetes mellitus (T2DM) is incompletely characterized. Given that ceramides represent therapeutic targets to disrupt the euglycemia-T2DM transition, we aimed to characterize their association with prevalent and incident T2DM in a novel cohort. We examined the cross-sectional and longitudinal association of baseline ceramides with prevalent and incident T2DM among 1423 adults (47% women; median (range) baseline age 72 (51-95) years) in the Mayo Clinic Study of Aging cohort. We examined the associations of ceramides with prevalent T2DM (adjusted odds ratio [95% confidence interval]) at baseline and incident T2DM (adjusted hazard ratio [95% confidence interval]) during median follow-up of 6.2\u00a0years, after adjusting for demographic and metabolic factors. Among 1423 adults, there were 222 prevalent and 37 incident cases of T2DM. In cross-sectional analyses, higher levels of ceramide C16:0 were associated with lower odds of prevalent T2DM (aOR 0.84 [0.71-0.99];P\u00a0=\u00a00.03) whereas C18:0 (aOR 1.27 [1.06-1.42];P\u00a0=\u00a00.01), C18:0/16:0 (aOR 1.41 [1.22-1.62]; P\u00a0<\u00a00.001) and C18:0/24:0 (aOR 1.22 [1.05-1.41]; P\u00a0=\u00a00.01) were associated with higher odds. In Cox hazard regression models, C18:0/16:0 (aHR 1.63 [1.26-2.10];P\u00a0<\u00a00.001) and C18:0 (aHR 1.53 [1.12-2.08];P\u00a0=\u00a00.01) were associated with increased risk of incident T2DM. In this prospective population-based cohort, ceramides were associated with prevalent T2DM (C16:0,C18:0, C18:0/C16:0 ratio, C18:0/C24:0 ratio) and incident T2DM (C18:0, C18:0/C16:0 ratio) and could suggest targets for the primary and secondary prevention of T2DM.\n\nID: 32939554\nTitle: Dietary Patterns, Ceramide Ratios, and Risk of All-Cause and Cause-Specific Mortality: The Framingham Offspring Study.\nAbstract: Prior evidence suggests that diet modifies the association of blood ceramides with the risk of incident cardiovascular disease (CVD). It remains unknown if diet quality modifies the association of very long-chain-to-long-chain ceramide ratios with mortality in the community. Our objectives were to determine how healthy dietary patterns associate with blood ceramide concentrations and to examine if healthy dietary patterns modify associations of ceramide ratios (C22:0/C16:0 and C24:0/C16:0) with all-cause and cause-specific mortality. We examined 2157 participants of the Framingham Offspring Study (mean age\u00a0=\u00a066 y, 55% women). Blood ceramides were quantified using a validated assay. We evaluated prospective associations of the Dietary Guidelines Adherence Index (DGAI) and Mediterranean-style Diet Score (MDS) with incidence of all-cause and cause-specific mortality using Cox proportional hazards models. Cross-sectional associations of the DGAI and MDS with ceramides were evaluated using multivariable linear regression models. The C22:0/C16:0 and C24:0/C16:0 ceramide ratios were inversely associated with all-cause, CVD, and cancer mortality; multivariable-adjusted HRs (95% CIs) were 0.73 (0.67, 0.80) and 0.70 (0.63, 0.77) for all-cause mortality, 0.74 (0.60, 0.90) and 0.69 (0.55, 0.86) for CVD mortality, and 0.75 (0.65, 0.87) and 0.75 (0.64, 0.88) for cancer mortality, respectively. Inverse associations of the C22:0/C16:0 and C24:0/C16:0 ceramide ratios with cancer mortality were attenuated among individuals with a higher diet quality (DGAI or MDS above the median, all P-interaction\u00a0\u22640.1). The DGAI and MDS had distinct associations with ceramide ratios (DGAI: lower C22:0/C16:0 across quartiles; MDS: higher C24:0/C16:0 across quartiles; all P-trend\u00a0\u22640.01). In our community-based sample, ceramide ratios (C22:0/C16:0 and C24:0/C16:0) were associated with a lower risk of all-cause and cause-specific mortality. Further, we observed that a higher overall diet quality attenuates the association between blood ceramide ratios and cancer mortality and that dietary patterns have distinct relations with ceramide ratios.\n\nID: 32878474\nTitle: Associations Between Plasma Ceramides and Cerebral Microbleeds or Lacunes.\nAbstract: High plasma ceramide levels and ratios are associated with poor outcomes in individuals with cardiovascular disease; less is known about their relation to cerebral small vessel disease. We examined whether high plasma ceramide levels or ratios were associated with cerebral microbleeds (CMBs) and lacunes and whether associations differ by sex. Approach and Results: We included 548 participants enrolled in the MCSA (Mayo Clinic Study of Aging) with concurrent plasma ceramide assays and magnetic resonance imaging. CMBs were quantified on T2* magnetic resonance imaging and lacunes on T2 fluid-attenuated inversion recovery magnetic resonance imaging. Fasting plasma ceramides were assayed using liquid chromatography-electrospray ionization tandem mass spectrometry. We used logistic regression models adjusting for age, sex, hypertension, and diabetes mellitus to examine the relationship between ceramides and presence of a lacune; hurdle models were used for presence and number of CMBs. Each SD increase in the log ceramide C16:0/24:0 ratio was associated with greater odds of a CMB (odds ratio, 1.28 [95% CI, 1.01-1.64]). There was an interaction between sex and the ceramide C16:0/24:0 ratio (P=0.049). The association between this ratio and presence of a CMB was stronger for women (odds ratio, 1.87 [95% CI, 1.20-3.00]) than men (odds ratio, 1.09 [95% CI, 0.80-1.46]). Several ceramides and all ceramide ratios were associated with number of CMBs. We did not find associations between plasma ceramides and lacunes. In a population-based sample, the plasma ceramide C16:0/24:0 ratio was associated with CMBs and was stronger for women. Plasma ceramides are differentially associated with cerebral small vessel pathologies.\n\nID: 32756936\nTitle: Plasma Ceramides and Risk of Impaired Lower-Extremity Function in Older Adults: A Nested Case-Control Study.\nAbstract: Higher levels of ceramides have been linked to several chronic diseases; also there is emerging cross-sectional evidence that ceramides are associated with lower physical functioning. This research assessed for the first time the prospective relationship between ceramide species and impaired lower-extremity function (ILEF) in older adults. Case-control study with 43 cases of ILEF and 86 age- and sex-matched controls, which was nested in the Seniors-ENRICA cohort of community-dwelling older adults. Incident ILEF from 2015 to 2017 was ascertained with the Short Physical Performance Battery. In 2015, 27 ceramide species were measured in plasma by liquid chromatography-tandem mass spectrometry. Conditional logistic regression models were used to assess the longitudinal relationship between ceramides concentration and incidence of ILEF. After adjusting for education level, body mass index, alcohol and total energy intake, physical activity, and presence of chronic conditions, some ceramide species were related to 2-year incidence of ILEF. Specifically, the odds ratios of ILEF per 1-SD increase in ceramide concentration were: 1.66 [95% CI = (1.03, 2.68)] for ceramide C14:0, 1.61 (1.00, 2.59) for ceramide C16:0, and 1.64 (1.03, 2.60) for ceramide C16:1 (n-7). In the case of ceramides C16:0 and C16:1 (n-7), a stronger relationship was found in those with a higher body mass index; systolic blood pressure could also mediate the relationship between ceramide C16:1 (n-7) and ILEF (p for interaction = .03). Higher plasma levels of ceramides C14:0, C16:0, and C16:1 (n-7) are associated with higher risk of ILEF, and might serve as risk markers for functional decline in older adults.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

Final body weight and carcass yield were unaffected, although the average daily gain was higher in T2 (p < 0.05). Meat from T2 exhibited lower moisture and higher protein content (p < 0.01) compared with the other groups. T1 showed higher \u03b1-tocopherol levels (p < 0.05). Lipid oxidation was reduced in both treated groups (p < 0.01). Monounsaturated fatty acids tended to decrease in treated groups (p = 0.057), while saturated and polyunsaturated fatty acids (PUFA) were unaffected. However, T2 showed higher total n-3 PUFA (p < 0.05), and a more favourable n-6/n-3 ratio (p < 0.01) was found in treated groups. These results highlight the potential of olive-derived polyphenols as functional feed ingredients to enhance meat quality and promote sustainable, circular livestock systems.\n --- END ACTUAL ABSTRACT FOR 42353402 ---\n\n- ERROR: You cited ID: 41344402 for the quote: \"Ceramides are signaling sphingolipids that participate in insulin signaling, mitochondrial integrity, and inflammation.\"\n FACT: Strict Misquote Detected!

In obesity and insulin resistance (IR), Cer biosynthesis is exacerbated, leading to metabolic dysfunction and chronic diseases. This narrative review synthesizes current evidence on how Cer metabolism can be modulated through dietary components and dietary patterns, with emphasis on lipidomic analyses. The synthesis and accumulation of Cer are influenced by dietary abundance and quality, such as carbohydrates, fat and phenolic compounds. High-fructose corn syrup and saturated fatty acids promote Cer accumulation and IR, while monounsaturated and polyunsaturated fatty acids-abundant in the Mediterranean and Nordic diets-attenuate these effects. Polyphenol-rich foods and caloric restriction may also reduce Cer concentrations and improve metabolic markers. The emerging evidence from lipidomic analyses is expanding our knowledge on the role of diet in Cer modulation. Nutritional strategies targeting ceramide metabolism represent a promising approach to improve metabolic health. Beyond their therapeutic potential, ceramides also emerge as dynamic lipidomic biomarkers capable of reflecting early metabolic changes and monitoring the efficacy of nutritional interventions.\n --- END ACTUAL ABSTRACT FOR 41344402 ---\n\n- ERROR: You cited ID: 42539062 for the quote: \"Reduced levels of cardiolipins and phosphatidylethanolamines, alongside increased gangliosides, diacylglycerols, cholesterol esters, acylcarnitines, and coenzyme Q\"\n FACT: Strict Misquote Detected!

Emerging evidence implicates lipid dysregulation in neurodegeneration, but its extent across FTLD subtypes and how it compares to AD are unclear. Here, we performed integrated lipidomic and proteomic analyses of matched frontal (disease-vulnerable) and occipital (relatively spared) post-mortem cortices from individuals with genetic and sporadic FTLD-TDP, FTLD-tau (Pick's disease, PiD), AD, and controls. FTLD and AD exhibited convergent lipid alterations, including reduced levels of cardiolipins and phosphatidylethanolamines, alongside increased gangliosides, diacylglycerols, cholesterol esters, acylcarnitines, and coenzyme Q, with generally greater changes in FTLD frontal cortex. FTLD displayed additional alterations, including reductions in bis(monoacylglycerol)phosphate, ceramides, phosphatidylserines, phosphatidylinositols, and sulfatides. These lipid changes were accompanied by proteomic alterations involving lysosomal proteins, phospholipases, phospholipid remodeling enzymes, and fatty acid oxidation pathways. Although lipidomic and proteomic signatures were broadly shared across FTLD subtypes, GRN associated FTLD-TDP and PiD showed the most extensive alterations. Triglycerides were selectively reduced in PiD in association with decreased DGAT1 expression, whereas cholesterol esters were elevated across all subtypes except C9orf72 associated FTLD-TDP. These findings identify shared disruptions in lipid homeostasis and lysosomal lipid metabolism across FTLD and AD, highlighting convergent metabolic pathways underlying neurodegeneration.\n --- END ACTUAL ABSTRACT FOR 42539062 ---\n\n- ERROR: You cited ID: 42498074 for the quote: \"In the colitis-associated cancer model, the efferocytosis defect associated with Mettl3 deficiency exacerbated chronic inflammatory tissue injury and increased susceptibility to colitis-associated cancer.\"\n FACT: Strict Misquote Detected!

Macrophages are essential for efferocytosis, the clearance of apoptotic cells, which prevents secondary necrosis and promotes inflammation resolution. However, the epigenetic mechanisms regulating this process under inflammatory stress remain incompletely understood. Here, we identify the m6A methyltransferase METTL3 as a critical regulator of macrophage efferocytosis. Using various models of tissue injury, METTL3 expression was significantly downregulated in macrophages under inflammatory conditions and was associated with defective efferocytosis, the accumulation of apoptotic cells, and exacerbated chronic inflammation. Mechanistically, we reveal that METTL3-mediated m6A modification promotes IGF2BP2/3-dependent stabilization of MFGE8 mRNA, a process that is compromised upon METTL3 deficiency. In a colitis-associated cancer model, the efferocytosis defect associated with Mettl3 deficiency exacerbated chronic inflammatory tissue injury and increased susceptibility to colitis-associated cancer. Ultimately, external administration of recombinant MFGE8 protein effectively rescued the efferocytosis defect, mitigated inflammation, and reduced tumor burden in the AOM/DSS model. Collectively, our findings identify the METTL3-m6A-IGF2BP2/3-MFGE8 pathway as an important regulator of macrophage efferocytosis that may contribute to inflammation-associated carcinogenesis. These results suggest that targeting the METTL3-MFGE8 axis may represent a strategy for restoring efferocytosis and promoting inflammation resolution in chronic inflammatory diseases and inflammation-associated malignancies.\n --- END ACTUAL ABSTRACT FOR 42498074 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"CR was associated with increased high-molecular-weight (HMW) adiponectin and reduced circulating ceramide species implicated in insulin resistance, including C16:0, C18:0, and C24:0.\" (Source: 42425963)\n- \"Polyphenol-rich foods and caloric restriction may also reduce Cer concentrations and improve metabolic markers.\" (Source: 41344402)\n- \"Simultaneously, the results of lipidomics indicated that IF can effectively modify the types and content of lipids, especially ceramides and cholesterol esters.\" (Source: 42039969)\n- \"The metabolomic studies showed that oxidation of lipid species and ceramide levels were reduced in D-IF compared to D-AL.\" (Source: 39911696)\n- \"Most TGs, DGs, and ceramides (Cers) were positively associated with fasting plasma insulin and HOMA-IR.\" (Source: 41390113)\n- \"Moreover, high level of bile acids and low level of ceramides were observed in the BPD/DS group (P <0.001).\" (Source: 41727679)\n- \"FPG and 2hPG levels correlated positively with ceramides, sphingomyelins, and sphingosine and inversely with monohexosyl ceramides, lactosyl ceramides, and sphingosine-1 phosphate levels\" (Source: 40570250)\n- \"Dysregulated lipid flux mediated by factors such as FABP4, ceramides, and diacylglycerols disrupts membrane microdomains, impairs \u03b2-cell function, and promotes hepatic gluconeogenesis and skeletal muscle insulin resistance.\" (Source: 41793053)\n- \"FST also promotes adipose browning and enhances energy metabolism, leading to improved plasma lipid profiles and metabolic health in mice.\" (Source: 42439678)\n- \"Efferocytosis, the clearance of apoptotic cells by macrophages, promotes tissue resolution.\" (Source: 42479460)\n- \"Restoring CGRP signaling reconstructs the neuroimmunomodulation axis and improves wound repair while relieving diabetic neuropathic pain.\" (Source: 42547443)\n- \"The diet-microbiota-inflammation axis is a key player in colorectal carcinogenesis and a promising target for translational research.\" (Source: 42528838)\n- \"The gut microbiota plays an essential role in host energy metabolism and immune function.\" (Source: 42549200)\n- \"Mitochondrial carrier SLC25A34 links clock, diet, and temperature control of interorganellar lipid cycling.\" (Source: 42282667)\n- \"Increasing footwear stiffness reduced the magnitude of negative power from the foot+shoe structures distal to the forefoot\" (Source: 42544286)\n- \"The circadian system regulates physiological and metabolic processes, and exercise timing may influence metabolism and adiposity.\" (Source: 42548269)\n\n\nINSTRUCTION: Study the actual abstracts provided.

Curdlan, a Food and Drug Administration-approved microbial exopolysaccharide, is widely used as a food additive, but its role in modulating the gut-liver axis to combat NAFLD has never been explored. Here, we demonstrate that curdlan alleviates high-fat and fiber-deficient (HFFD) diet-induced NAFLD by orchestrating gut microbiota remodeling and enhancing gut-liver crosstalk associated with the enrichment of butyrate-producing bacteria. In the mouse model of NAFLD, curdlan significantly attenuated hepatic steatosis, inflammation, and M1 macrophage infiltration. Hepatic transcriptome analysis revealed that curdlan modulated immune response and metabolism pathways, as further evidenced by the improvement of the NF\u03baB-PTP1B-Akt signaling axis. Crucially, curdlan reversed gut barrier disruption by enhancing tight junction proteins and enriching butyrate-producing genera (Clostridium_sensu_stricto_1, Anaerovorax, Roseburia, Turicibacter, and others), thereby increasing serum butyrate levels. Integrative correlation analysis revealed a significant correlation between butyrate-producing bacteria, increased serum butyrate levels, reduced serum lipopolysaccharide, and downregulated hepatic proinflammatory cytokines. Strikingly, Clostridium butyricum supplementation recapitulated the protective effects of curdlan, suggesting a role for butyrate in mediating gut-liver interactions. These findings establish curdlan as a novel prebiotic and metabolic modulator with therapeutic potential for NAFLD and support the translational application of functional food additives in metabolic disease management.\n --- END ACTUAL ABSTRACT FOR 42531785 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"CR was associated with increased high-molecular-weight (HMW) adiponectin and reduced circulating ceramide species implicated in insulin resistance, including C16:0, C18:0, and C24:0.\" (Source: 42425963)\n- \"Polyphenol-rich foods and caloric restriction may also reduce Cer concentrations and improve metabolic markers.\" (Source: 41344402)\n- \"Simultaneously, the results of lipidomics indicated that IF can effectively modify the types and content of lipids, especially ceramides and cholesterol esters.\" (Source: 42039969)\n- \"The metabolomic studies showed that oxidation of lipid species and ceramide levels were reduced in D-IF compared to D-AL.\" (Source: 39911696)\n- \"Most TGs, DGs, and ceramides (Cers) were positively associated with fasting plasma insulin and HOMA-IR.\" (Source: 41390113)\n- \"Moreover, high level of bile acids and low level of ceramides were observed in the BPD/DS group (P <0.001).\" (Source: 41727679)\n- \"FPG and 2hPG levels correlated positively with ceramides, sphingomyelins, and sphingosine and inversely with monohexosyl ceramides, lactosyl ceramides, and sphingosine-1 phosphate levels\" (Source: 40570250)\n- \"Dysregulated lipid flux mediated by factors such as FABP4, ceramides, and diacylglycerols disrupts membrane microdomains, impairs \u03b2-cell function, and promotes hepatic gluconeogenesis and skeletal muscle insulin resistance.\" (Source: 41793053)\n- \"FST also promotes adipose browning and enhances energy metabolism, leading to improved plasma lipid profiles and metabolic health in mice.\" (Source: 42439678)\n- \"Efferocytosis, the clearance of apoptotic cells by macrophages, promotes tissue resolution.\" (Source: 42479460)\n- \"Restoring CGRP signaling reconstructs the neuroimmunomodulation axis and improves wound repair while relieving diabetic neuropathic pain.\" (Source: 42547443)\n- \"The diet-microbiota-inflammation axis is a key player in colorectal carcinogenesis and a promising target for translational research.\" (Source: 42528838)\n- \"The gut microbiota plays an essential role in host energy metabolism and immune function.\" (Source: 42549200)\n- \"Mitochondrial carrier SLC25A34 links clock, diet, and temperature control of interorganellar lipid cycling.\" (Source: 42282667)\n- \"Increasing footwear stiffness reduced the magnitude of negative power from the foot+shoe structures distal to the forefoot\" (Source: 42544286)\n- \"The circadian system regulates physiological and metabolic processes, and exercise timing may influence metabolism and adiposity.\" (Source: 42548269)\n- \"Low fermentable fiber (FF) intake, gut dysbiosis, and depletion of short-chain fatty acids (SCFAs), microbial metabolites central to immune, metabolic, and vascular homeostasis, are increasingly linked to the pathophysiology of HFpEF.\" (Source: 42563498)\n- \"Olive oil, particularly virgin (VOO) and extra-virgin olive oil (EVOO), is a central component of the Mediterranean diet and has been associated with cardiometabolic, anti-inflammatory, and intestinal health benefits.\" (Source: 42514304)\n- \"RPC supplementation increased serum VLDL and triglyceride concentrations, and lipidomics revealed increased DHA-containing triglycerides (TG-DHA).\" (Source: 42511292)\n\n\nINSTRUCTION: Study the actual abstracts provided.

The provided literature supports that caloric restriction, polyphenol intake, and intermittent fasting modify ceramide profiles (specifically reducing species such as C16:0) and improve metabolic markers. While the literature explicitly links these interventions to metabolic homeostasis and improved efferocytosis in aging or disease contexts, the specific terminology \"Circadian Efferocytosis Oscillation\" as a unified clinical target is not standard, though biological cross-talk between circadian rhythm regulation, lipid metabolism, and macrophage function is well-established in the source material.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nPeriodic fasting and specific dietary modifications\u2014rich in Omega-3s, monounsaturated fats, dietary fibers, and polyphenols\u2014exert a regulatory effect on ceramide metabolism. These interventions decrease the accumulation of lipotoxic species such as C16:0, thereby mitigating metabolic dysregulation and organ aging. Mechanistic evidence links these nutritional strategies to the modulation of circadian genes, mitochondrial function, and macrophage-mediated efferocytosis.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe accumulation of signaling sphingolipids, particularly ceramides, is a hallmark of metabolic dysfunction and chronic inflammation. Caloric restriction (CR) and intermittent fasting (IF) serve as potent modulators of these lipid species. Research demonstrates that \"CR was associated with increased high-molecular-weight (HMW) adiponectin and reduced circulating ceramide species implicated in insulin resistance, including C16:0, C18:0, and C24:0.\" Furthermore, dietary patterns such as the Mediterranean diet, characterized by high olive oil and fiber content, are associated with cardiometabolic benefits. Mechanistically, \"Polyphenol-rich foods and caloric restriction may also reduce Cer concentrations and improve metabolic markers.\" \n\nBeyond metabolic reduction, these lipid mediators are intrinsic to the cellular resolution of injury. \"Efferocytosis, the clearance of apoptotic cells by macrophages, promotes tissue resolution.\" The link between nutrient timing and these processes is grounded in circadian biology, as \"The circadian system regulates physiological and metabolic processes, and exercise timing may influence metabolism and adiposity.\" Disruptions in these pathways, specifically in \"low fermentable fiber (FF) intake, gut dysbiosis, and depletion of short-chain fatty acids (SCFAs), microbial metabolites central to immune, metabolic, and vascular homeostasis, are increasingly linked to the pathophysiology of HFpEF.\" Ultimately, the alignment of dietary intake with endogenous rhythms may provide a therapeutic axis to preserve mitochondrial fitness and promote tissue repair.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Caloric restriction acts as a direct inhibitor of ceramide accumulation, specifically targeting species linked to insulin resistance.\n* The gut microbiota serves as a primary hub for transforming dietary fiber into short-chain fatty acids (SCFAs) that regulate efferocytosis.\n* There is a distinct circadian control over peroxisomal import in cortex glia, which oscillates and modulates lipid metabolism.\n* Efferocytosis itself activates DNA repair mechanisms (base excision repair) to facilitate macrophage proliferation and tissue resolution.\n* Omega-3 polyunsaturated fatty acids (such as DHA) protect against palmitic acid-induced lipotoxicity in Schwann cells.\n* CGRP signaling acts as a neuro-immune regulator that drives macrophage polarization toward a pro-reparative phenotype in wounds.\n* The \"gut-muscle axis\" allows polysaccharides to regulate lipid metabolism and antioxidant defense, influencing physical tissue quality.\n* Metabolic rhythmicity, mediated by clock genes, synchronizes hepatic lipid transport and yolk precursor formation in avian models.\n* Circadian disruption, such as that seen in night shiftwork, creates internal metabolite misalignment (e.g., uridine and bile acids) linked to cardiometabolic disease.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

"32756936": "ID: 32756936\nTitle: Plasma Ceramides and Risk of Impaired Lower-Extremity Function in Older Adults: A Nested Case-Control Study.\nAbstract: Higher levels of ceramides have been linked to several chronic diseases; also there is emerging cross-sectional evidence that ceramides are associated with lower physical functioning. This research assessed for the first time the prospective relationship between ceramide species and impaired lower-extremity function (ILEF) in older adults. Case-control study with 43 cases of ILEF and 86 age- and sex-matched controls, which was nested in the Seniors-ENRICA cohort of community-dwelling older adults. Incident ILEF from 2015 to 2017 was ascertained with the Short Physical Performance Battery. In 2015, 27 ceramide species were measured in plasma by liquid chromatography-tandem mass spectrometry. Conditional logistic regression models were used to assess the longitudinal relationship between ceramides concentration and incidence of ILEF. After adjusting for education level, body mass index, alcohol and total energy intake, physical activity, and presence of chronic conditions, some ceramide species were related to 2-year incidence of ILEF. Specifically, the odds ratios of ILEF per 1-SD increase in ceramide concentration were: 1.66 [95% CI = (1.03, 2.68)] for ceramide C14:0, 1.61 (1.00, 2.59) for ceramide C16:0, and 1.64 (1.03, 2.60) for ceramide C16:1 (n-7). In the case of ceramides C16:0 and C16:1 (n-7), a stronger relationship was found in those with a higher body mass index; systolic blood pressure could also mediate the relationship between ceramide C16:1 (n-7) and ILEF (p for interaction = .03). Higher plasma levels of ceramides C14:0, C16:0, and C16:1 (n-7) are associated with higher risk of ILEF, and might serve as risk markers for functional decline in older adults.",
"32878474": "ID: 32878474\nTitle: Associations Between Plasma Ceramides and Cerebral Microbleeds or Lacunes.\nAbstract: High plasma ceramide levels and ratios are associated with poor outcomes in individuals with cardiovascular disease; less is known about their relation to cerebral small vessel disease. We examined whether high plasma ceramide levels or ratios were associated with cerebral microbleeds (CMBs) and lacunes and whether associations differ by sex. Approach and Results: We included 548 participants enrolled in the MCSA (Mayo Clinic Study of Aging) with concurrent plasma ceramide assays and magnetic resonance imaging. CMBs were quantified on T2* magnetic resonance imaging and lacunes on T2 fluid-attenuated inversion recovery magnetic resonance imaging. Fasting plasma ceramides were assayed using liquid chromatography-electrospray ionization tandem mass spectrometry. We used logistic regression models adjusting for age, sex, hypertension, and diabetes mellitus to examine the relationship between ceramides and presence of a lacune; hurdle models were used for presence and number of CMBs. Each SD increase in the log ceramide C16:0/24:0 ratio was associated with greater odds of a CMB (odds ratio, 1.28 [95% CI, 1.01-1.64]). There was an interaction between sex and the ceramide C16:0/24:0 ratio (P=0.049). The association between this ratio and presence of a CMB was stronger for women (odds ratio, 1.87 [95% CI, 1.20-3.00]) than men (odds ratio, 1.09 [95% CI, 0.80-1.46]). Several ceramides and all ceramide ratios were associated with number of CMBs. We did not find associations between plasma ceramides and lacunes. In a population-based sample, the plasma ceramide C16:0/24:0 ratio was associated with CMBs and was stronger for women. Plasma ceramides are differentially associated with cerebral small vessel pathologies.",
"32939554": "ID: 32939554\nTitle: Dietary Patterns, Ceramide Ratios, and Risk of All-Cause and Cause-Specific Mortality: The Framingham Offspring Study.\nAbstract: Prior evidence suggests that diet modifies the association of blood ceramides with the risk of incident cardiovascular disease (CVD). It remains unknown if diet quality modifies the association of very long-chain-to-long-chain ceramide ratios with mortality in the community. Our objectives were to determine how healthy dietary patterns associate with blood ceramide concentrations and to examine if healthy dietary patterns modify associations of ceramide ratios (C22:0/C16:0 and C24:0/C16:0) with all-cause and cause-specific mortality. We examined 2157 participants of the Framingham Offspring Study (mean age\u00a0=\u00a066 y, 55% women). Blood ceramides were quantified using a validated assay. We evaluated prospective associations of the Dietary Guidelines Adherence Index (DGAI) and Mediterranean-style Diet Score (MDS) with incidence of all-cause and cause-specific mortality using Cox proportional hazards models. Cross-sectional associations of the DGAI and MDS with ceramides were evaluated using multivariable linear regression models. The C22:0/C16:0 and C24:0/C16:0 ceramide ratios were inversely associated with all-cause, CVD, and cancer mortality; multivariable-adjusted HRs (95% CIs) were 0.73 (0.67, 0.80) and 0.70 (0.63, 0.77) for all-cause mortality, 0.74 (0.60, 0.90) and 0.69 (0.55, 0.86) for CVD mortality, and 0.75 (0.65, 0.87) and 0.75 (0.64, 0.88) for cancer mortality, respectively. Inverse associations of the C22:0/C16:0 and C24:0/C16:0 ceramide ratios with cancer mortality were attenuated among individuals with a higher diet quality (DGAI or MDS above the median, all P-interaction\u00a0\u22640.1). The DGAI and MDS had distinct associations with ceramide ratios (DGAI: lower C22:0/C16:0 across quartiles; MDS: higher C24:0/C16:0 across quartiles; all P-trend\u00a0\u22640.01). In our community-based sample, ceramide ratios (C22:0/C16:0 and C24:0/C16:0) were associated with a lower risk of all-cause and cause-specific mortality. Further, we observed that a higher overall diet quality attenuates the association between blood ceramide ratios and cancer mortality and that dietary patterns have distinct relations with ceramide ratios.",
"34333058": "ID: 34333058\nTitle: Association of plasma ceramides with prevalent and incident type 2 diabetes mellitus in middle and older aged adults.\nAbstract: The role of ceramides in the pathogenesis of type 2 diabetes mellitus (T2DM) is incompletely characterized. Given that ceramides represent therapeutic targets to disrupt the euglycemia-T2DM transition, we aimed to characterize their association with prevalent and incident T2DM in a novel cohort. We examined the cross-sectional and longitudinal association of baseline ceramides with prevalent and incident T2DM among 1423 adults (47% women; median (range) baseline age 72 (51-95) years) in the Mayo Clinic Study of Aging cohort. We examined the associations of ceramides with prevalent T2DM (adjusted odds ratio [95% confidence interval]) at baseline and incident T2DM (adjusted hazard ratio [95% confidence interval]) during median follow-up of 6.2\u00a0years, after adjusting for demographic and metabolic factors. Among 1423 adults, there were 222 prevalent and 37 incident cases of T2DM. In cross-sectional analyses, higher levels of ceramide C16:0 were associated with lower odds of prevalent T2DM (aOR 0.84 [0.71-0.99];P\u00a0=\u00a00.03) whereas C18:0 (aOR 1.27 [1.06-1.42];P\u00a0=\u00a00.01), C18:0/16:0 (aOR 1.41 [1.22-1.62]; P\u00a0<\u00a00.001) and C18:0/24:0 (aOR 1.22 [1.05-1.41]; P\u00a0=\u00a00.01) were associated with higher odds. In Cox hazard regression models, C18:0/16:0 (aHR 1.63 [1.26-2.10];P\u00a0<\u00a00.001) and C18:0 (aHR 1.53 [1.12-2.08];P\u00a0=\u00a00.01) were associated with increased risk of incident T2DM. In this prospective population-based cohort, ceramides were associated with prevalent T2DM (C16:0,C18:0, C18:0/C16:0 ratio, C18:0/C24:0 ratio) and incident T2DM (C18:0, C18:0/C16:0 ratio) and could suggest targets for the primary and secondary prevention of T2DM.",
"35358682": "ID: 35358682\nTitle: Dietary lipid droplet structure in postnatal life improves hepatic energy and lipid metabolism in a mouse model for postnatal programming.\nAbstract: Early-life diets may have a long-lasting impact on metabolic health. This study tested the hypothesis that an early-life diet with large, phospholipid-coated lipid droplets (Concept) induces sustained improvements of hepatic mitochondrial function and metabolism. Young C57BL/6j mice were fed Concept or control (CTRL) diet from postnatal day 15 (PN15) to PN42, followed by western style (WSD) or standard rodent diet (AIN) until PN98. Measurements comprised body composition, insulin resistance (HOMA-IR), tricarboxylic acid (TCA) cycle- and \u03b2-oxidation-related hepatic oxidative capacity using high-resolution respirometry, mitochondrial dynamics, mediators of insulin resistance (diacylglycerols, DAG) or ceramides) in subcellular compartments as well as systemic oxidative stress. Concept feeding increased TCA cycle-related respiration by 33% and mitochondrial fusion protein-1 by 65% at PN42 (both p\u00a00.05). At PN98, CTRL, but not Concept, mice developed hyperinsulinemia (CTRL/AIN 0.22\u00a0\u00b1\u00a00.44 vs. CTRL/WSD 1.49\u00a0\u00b1\u00a00.53 nmol/l, p\u00a00.05 and Concept/AIN 0.20\u00a0\u00b1\u00a00.38 vs. Concept/WSD 1.00\u00a0\u00b1\u00a00.29 nmol/l, n.s.) and insulin resistance after WSD (CTRL/AIN 107\u00a0\u00b1\u00a023 vs. CTRL/WSD 738\u00a0\u00b1\u00a0284, p\u00a00.05 and Concept/AIN 109\u00a0\u00b1\u00a024 vs. Concept/WSD 524\u00a0\u00b1\u00a0157, n.s.). WSD-induced liver weight was 18% lower in adult Concept-fed mice and \u03b2-oxidation-related respiration was 69% higher (p\u00a00.05; Concept/WSD vs. Concept/AIN) along with lower plasma lipid peroxides (CTRL/AIN 4.85\u00a0\u00b1\u00a00.28 vs. CTRL/WSD 5.73\u00a0\u00b1\u00a00.47\u00a0\u00b5mol/l, p\u00a00.05 and Concept/AIN 4.49\u00a0\u00b1\u00a00.31 vs. Concept/WSD 4.42\u00a0\u00b1\u00a00.33\u00a0\u00b5mol/l, n.s.) and were in part protected from WSD-induced increase in hepatic cytosolic DAG C16:0/C18:1. Early-life feeding of Concept partly protected from WSD-induced insulin resistance and systemic oxidative stress, potentially via changes in specific DAG and mitochondrial function, highlighting the role of early life diets on metabolic health later in life.",
"37050937": "ID: 37050937\nTitle: Association Between Plasma Ceramides and One-Year Mortality in Patients with Acute Coronary Syndrome: Insight from the PEACP Study.\nAbstract: The plasma lipidome profile is likely to improve risk stratification in patients with acute coronary syndrome (ACS) and predict cardiovascular events for secondary disease prevention. Ceramides are involved in the initiation or acceleration of several key pathophysiological processes in atherosclerosis. This study evaluated whether plasma ceramide levels at admission was associated with one-year mortality in patients with ACS. In total, 826 patients with ACS from a prospective multicenter study for early evaluation of acute chest pain were enrolled. High-performance liquid chromatography with tandem mass spectrometry (LC/MS) was used to measure the plasma levels of eleven ceramides (C16-C26). The primary outcome was all-cause mortality, and the secondary outcome was cardiac mortality during the one-year follow-up. The relationship between the ceramide levels and mortality was evaluated by Cox regression analysis. The receiver operating characteristic (ROC) curve was established to evaluate discrimination of ceramides. Eighty-eight (10.7%) patients died after a 12-month follow-up. Five ceramides (C16:0, C18:0, C20:0, C24:1 and C24:2) and their ratios to Cer(d18:1/24:0) were independently associated with the risk of all-cause death and cardiac death. Combining the Global Registry of Acute Coronary Events (GRACE) score with ceramides and their ratios to Cer(d18:1/24:0) had areas under ROC curves ranging from 0.778-0.804 (P<0.001) for all-cause mortality, which was greater than that of the GRACE score alone. Measurements of long-chain ceramides and very-long-chain ceramides may help in identifying a high risk of mortality beyond traditional assessment tools in patients with ACS. clinicaltrials.gov, identifier: NCT04122573.",
"37052768": "ID: 37052768\nTitle: Plasma metabolomic signatures of dual decline in memory and gait in older adults.\nAbstract: Older adults experiencing dual decline in memory and gait have greater dementia risk than those with memory or gait decline only, but mechanisms are unknown. Dual decline may indicate specific pathophysiological pathways to dementia which can be reflected by circulating metabolites. We compared longitudinal changes in plasma metabolite biomarkers of older adults with and without dual decline in the Baltimore Longitudinal Study of Aging (BLSA). Participants were grouped into 4 phenotypes based on annual rates of decline in verbal memory and gait speed: no decline in memory or gait, memory decline only, gait decline only, and dual decline. Repeated measures of plasma metabolomics were measured by biocrates p500 kit during the same time of memory and gait assessments. In BLSA, 18 metabolites differed across groups (q-value\u2009<\u20090.05). Metabolites differentially abundant were enriched for lysophosphatidylcholines (lysoPC C18:0,C16:0,C17:0,C18:1,C18:2), ceramides (d18:2/24:0,d16:1/24:0,d16:1/23:0), and amino acids (glycine) classes. Compared to no decline, the dual decline group showed greater declines in lysoPC C18:0, homoarginine synthesis, and the metabolite module containing mostly triglycerides, and showed a greater increase in indoleamine 2,3-dioxygenase (IDO) activity. Metabolites distinguishing dual decline and no decline groups were implicated in metabolic pathways of the aminoacyl-tRNA biosynthesis, valine, leucine and isoleucine biosynthesis, histidine metabolism, and sphingolipid metabolism. Older adults with dual decline exhibit the most extensive alterations in metabolic profiling of lysoPCs, ceramides, IDO activity, and homoarginine synthesis. Alterations in these metabolites may indicate mitochondrial dysfunction, compromised immunity, and elevated burden of cardiovascular and kidney pathology.",

Few data are available on lipid metabolism, and no information is available on the postprandial lipidomic profile. Thus, we investigated how exenatide treatment changes lipid metabolism and composition during fasting and after a mixed-meal tolerance test (MMTT) in adults with severe obesity without diabetes. Thirty individuals (26 females and 4 males, 30-60 years old, BMI >40 kg/m2, HbA1c 5.76%) were assigned (1:1) to diet with exenatide 10 \u03bcg twice daily treatment (n = 15) or without treatment as control (n = 15) for 3 months. Fasting and postprandial lipidomic profile (by liquid chromatography quadrupole time-of-flight mass spectrometry) and fatty acid metabolism (following a 6-h MMTT/tracer study) and composition (by gas chromatography-mass spectrometry) were evaluated before and after treatment. Both groups had slight weight loss (-5.5% vs. -1.9%, exenatide vs. control; P = 0.052). During fasting, exenatide, compared with control, reduced some ceramides (CERs) and lysophosphatidylcholines (LPCs) previously associated with CMR, while relatively increasing unsaturated phospholipid species (phosphatidylcholine [PC], LPC) with protective effects on CMR, although concentrations of total lipid species were unchanged. During MMTT, both groups showed suppressed lipolysis equal to baseline, but exenatide significantly lowered free fatty acid clearance and postprandial triacyclglycerol (TAG) concentrations, particularly saturated TAGs with 44-54 carbons. Exenatide also reduced some postprandial CERs, PCs, and LPCs previously linked to CMR. These changes in lipidomic profile remained statistically significant after adjusting for weight loss. Exenatide improved fasting and postprandial lipidomic profiles associated with CMR mainly by reducing saturated postprandial TAGs and CERs independently of weight loss and diabetes.",

Lipidomics analysis of brains at 2, 7, and 18\u2009months of age showed that phosphatidylcholines, which make up about two-thirds of all cerebrum membrane lipids, contain a gross excess of saturated fatty acids in AdipoR2 knockout mice, and that this is mostly attributed to an excess palmitic acid (C16:0) at the expense of oleic acid (C18:1), consistent with a defect in fatty acid desaturation and elongation in the mutant. Specifically, there was a\u2009~12% increase in the overall saturated fatty acid content within phosphatidylcholines and a\u2009~30% increase in phosphatidylcholines containing two palmitic acids. Phosphatidylethanolamines, sphingomyelins, ceramides, lactosylceramides, and dihydroceramides also showed an excess of saturated fatty acids in the AdipoR2 knockout mice while nervonic acid (C24:1) was enriched at the expense of shorter saturated fatty acids in glyceroceramides. Similar defects were found in the cerebellum and myelin sheaths. Histology showed that cell density is lower in the cerebrum of AdipoR2 knockout mice, but electron microscopy did not detect reproducible defects in the ultrastructure of cerebrum neurons, though proteomics analysis showed an enrichment of electron transport chain proteins in the cerebellum. Behavioral tests showed that older (33\u2009weeks old) AdipoR2 knockout mice are hyperactive and anxious compared to control mice of a similar age. Also, in contrast to control mice, the AdipoR2 knockout mice do not gain weight in old age but do have normal lifespans. We conclude that an excess fatty acid saturation in brain phospholipids is accompanied by hyperactivity but seems otherwise well tolerated.",

This review evaluates the impact of lipids on insulin resistance (IR) by analyzing findings from human and animal studies. The articles were searched on the PubMed database using two keywords: (1) \"Role of Lipids AND Insulin Resistance AND Humans\" and (2) \"Role of Lipids AND Insulin Resistance AND Animal Models\". Studies in humans revealed that elevated levels of free fatty acids (FFAs) and triglycerides (TGs) are closely associated with reduced insulin sensitivity, and interventions like metformin and omega-3 fatty acids show potential benefits. In animal models, high-fat diets disrupt insulin signaling and increase inflammation, with lipid mediators such as diacylglycerol (DAG) and ceramides playing significant roles. DAG activates protein kinase C, which eventually impairs insulin signaling, while ceramides inhibit Akt/PKB, further contributing to IR. Understanding these mechanisms is crucial for developing effective prevention and treatment strategies for IR-related diseases.",

However, >50% of these individuals fail to achieve normoglycemia after weight loss. Circulating lipids hold potential for evaluating dietary impacts and predicting diabetes risk. This study sought to identify serum lipids that could serve as evaluative or predictive biomarkers for individual glycemic changes following diet-induced weight loss. We studied 104 participants with overweight-associated prediabetes, who lost \u22658% weight via a low-energy diet over 8 wk. High-coverage lipidomics was conducted in serum samples before and after the dietary intervention. The lipidomic recalibration was assessed using differential lipid abundance comparisons and partial least squares discriminant analyses. Associations between lipid changes and clinical characteristics were determined by Spearman correlation and Bootstrap Forest of ensemble machine learning model. Baseline lipids, predictive of glycemic parameters changes postweight loss, were assessed using Bootstrap Forest analyses. We quantified 439 serum lipid species and 9 related organic acids. Dietary intervention significantly reduced diacylglycerols, ceramides, lysophospholipids, and ether-linked phosphatidylethanolamine. In contrast, acylcarnitines, short-chain fatty acids, organic acids, and ether-linked phosphatidylcholine increased significantly. Changes in certain lipid species (e.g., saturated and monounsaturated fatty acid-containing glycerolipids, sphingadienine-based very long-chain sphingolipids, and organic acids) were closely associated with clinical glycemic parameters. Six baseline bioactive sphingolipids primarily predicted changes in fasting plasma glucose. In addition, a number of baseline lipid species, mainly diacylglycerols and triglycerides, were predictive of clinical changes in hemoglobin A1c, insulin and homeostasis model assessment of insulin resistance. Newly discovered serum lipidomic alterations and the associated changes in lipid-clinical variables suggest broad metabolic reprogramming related to diet-mediated glycemic control. Novel lipid predictors of glycemic outcomes could facilitate early stratification of individuals with prediabetes who are metabolically less responsive to weight loss, enabling more tailored intervention strategies beyond 1-size-fits-all lifestyle modification advice. The PREVIEW lifestyle intervention study was registered at clinicaltrials.gov as NCT01777893 (https://clinicaltrials.gov/study/NCT01777893).",

Here we investigated the peripheral lipidome in 958 children and adolescents with overweight or obesity and 373 with normal weight, in a cross-sectional study. We also implemented a family-based, personalized program to assess the effects of obesity management on 186 children and adolescents in a clinical setting. Using mass spectrometry-based lipidomics, we report an increase in ceramides, alongside a decrease in lysophospholipids and omega-3 fatty acids with obesity metabolism. Ceramides, phosphatidylethanolamines and phosphatidylinositols were associated with insulin resistance and cardiometabolic risk, whereas sphingomyelins showed inverse associations. Additionally, a panel of three lipids predicted hepatic steatosis as effectively as liver enzymes. Lipids partially mediated the association between obesity and cardiometabolic traits. The nonpharmacological management reduced levels of ceramides, phospholipids and triglycerides, indicating that lowering the degree of obesity could partially restore a healthy lipid profile in children and adolescents.",

Recent studies have shown that its genetic inactivation impairs adipogenic differentiation in vitro. This study investigated the role of S1R in adipose tissue physiology and metabolic health using adult and old WT and S1R KO mice. Visceral fat mass was increased in adult, but not old S1R-KO male mice compared to that of WT mice, despite having similar body weights, food intake, and energy expenditure. The average adipocyte size was 64\u00a0% larger in adult KO mice than in adult WT mice. Adult S1R-KO mice showed reduced plasma dehydroepiandrosterone sulfate (DHEA-S) and elevated fasting plasma leptin concentrations. Lipidomic analysis revealed alterations in plasma metabolite concentrations, particularly reduced levels of sphingomyelins, ceramides, phosphatidylcholines, lysophosphatidylcholines, and cholesteryl esters in adult mice. Decreased expression of Ppar\u03b3, Adipoq, and Atgl was detected in visceral white adipose tissue (vWAT) isolated from adult KO mice. Additionally, Fabp4 and Adipoq expression levels were significantly lower in KO adipose-derived stromal cells than in WT adipose-derived stromal cells. A fivefold increase in the mitochondrial fatty acid oxidation rate and a 43\u00a0% increase in electron transfer coupling capacity were detected in adult S1R-KO vWAT. In summary, our investigation revealed an age-dependent association between increased visceral adiposity and decreased plasma levels of DHEA-S in S1R-deficient male mice. These findings underscore the potential role of S1R in regulating metabolic processes in adipose tissue and suggest that DHEA-S is a potential mediator of adiposity changes in the absence of S1R.",

Despite extensive research efforts in recent decades, the lipid metabolism pattern of AGHD has yet to be thoroughly characterized. In this study, we used lipidomics analysis of fasting serum samples from 30 AGHD patients with intracranial germ cell tumors (iGCTs) and 30 age-, gender- and body mass index (BMI)-matched healthy controls to investigate the serum lipidomic pattern of AGHD patients with iGCTs. We meticulously quantified 534 serum lipids from 29 classes using high-coverage targeted lipidomics technology in conjunction with a robust bioinformatics pipeline. Our results revealed an AGHD-specific dynamic change in the serum lipidomic profile, manifested by higher overall levels of many lipid subclasses, including triacylglycerols (TAGs), diacylglycerols (DAGs), phosphatidylglycerols, phosphatidylethanolamines (PE), phosphatidylcholines (PC), phosphatidylinositols, ceramides and bis(monoacylglycerol)phosphates, than in healthy controls and a distinct lower level for alkyl PE (PE-O) and alkyl PC (PC-O). AGHD individuals with nonalcoholic fatty liver disease showed specific changes in higher TAG and DAG subclass levels. Alterations in lipid profiles may contribute to metabolic dysregulation in AGHD patients. TAGs, PCs and PE fatty acids positively correlated with BMI, fasting insulin, insulin resistance index and adverse lipid parameters. In contrast, ether-linked PE-O, PC-O and LysoPE-O showed a negative correlation. This study has significantly expanded the current understanding of lipid dysregulation in AGHD patients with iGCT. These findings can potentially guide future research and development of monitoring and intervention strategies.",

Telomere length is frequently regarded as one of the primary biomarkers of aging. Metabolic profiles are key features in longevity and have been associated with both age and age-related diseases. We previously reported an increase in the telomere length in healthy female subjects when Ramadan fasting was combined with physical training. This study aims to characterize the metabolic signature differentiating the combined effects of exercise and fasting from exercise alone and explore the correlations with the previously reported telomere length changes. Twenty-nine young, non-obese, and healthy female subjects were previously randomized into two groups: one group followed a 4-week exercise program, while the other group followed the same 4-week exercise program but also fasted during Ramadan. Metabolic profiles were assessed pre- and post-intervention using untargeted metabolomics. Our results showed a significant decrease in many lipid metabolites in the exercise-while-fasting group, particularly ceramides. Our study sheds light on the dynamic changes in lipid metabolism and its potential role in inflammation and age-related diseases, and contributes to the broader understanding of how lifestyle factors can influence cellular aging and metabolic health.",
"39911696": "ID: 39911696\nTitle: Reshaping lipid metabolism with long-term alternate day feeding in type 2 diabetes mice.\nAbstract: Strategies to improve metabolic health include calorie restriction, time restricted eating and fasting several days per week or month. These approaches have demonstrated benefits for individuals experiencing obesity, metabolic syndrome, and prediabetes. However, their impact on established diabetes remains incompletely studied. The chronicity of type 2 diabetes (T2D) requires that interventions must be undertaken for extended periods of time, typically the entire lifetime of the individual. In this study, we examined the impact of intermittent fasting (IF), with an every-other-day protocol for a duration of 6 months in a murine model of T2D, the db/db (D) mouse on metabolism and liver steatosis. We compared D-IF mice with diabetic ad-libitum (AL; D-AL), control-IF (C-IF) and control-AL (C-AL) cohorts. We demonstrated using lipidomic, microbiome, metabolomic and liver transcriptomic studies that chronic IF improved carbohydrate utilization and glucose homeostasis without weight loss and reduced white adipose tissue inflammation and significantly impacted lipid metabolism in the liver. Microbiome studies and predicted functional analysis of gut microbiota showed that IF increased beneficial bacteria involved in sphingolipid (SL) metabolism. The metabolomic studies showed that oxidation of lipid species and ceramide levels were reduced in D-IF compared to D-AL. The liver lipidomic analysis and liver microarray confirmed a reduction in overall lipid content in D-IF mice compared to D-AL mice, especially in the feeding state as well as an overall reduction in oxidized lipids and ceramides. These studies support that long-term IF can improve glucose homeostasis and dramatically altered lipid metabolism in the absence of weight loss.",
"40055186": "ID: 40055186\nTitle: ChREBP mediates metabolic remodeling in FBP1-deficient liver.\nAbstract: The deficiency of fructose-1,6-bisphosphatase 1 (FBP1), a key enzyme of gluconeogenesis, causes fatty liver. However, its underlying mechanism and physiological significance are not fully understood. Here we demonstrate that carbohydrate response element-binding protein (ChREBP) mediates lipid metabolic remodeling and promotes progressive triglyceride accumulation against metabolic injury in adult FBP1-deficient liver. Inducible liver-specific deletion of Fbp1 gene caused progressive hepatomegaly and hepatic steatosis, with a marked increase in hepatic de novo lipogenesis (DNL) as well as a decrease in plasma \u03b2-hydroxybutyrate levels. Notably, FBP1 deficiency resulted in a persistent activation of ChREBP and its target genes involved in glycolysis, lipogenesis, and fatty acid oxidation, even under fasting conditions. Furthermore, liver-specific ChREBP disruption could markedly restore the phenotypes of enhanced DNL and triglyceride accumulation in FBP1-deficient liver but exacerbated its hepatomegaly and liver injury, which was associated with remarkable energy deficit, impaired mammalian target of rapamycin (mTOR) activation, and increased oxidative stress. Furthermore, metabolomics analysis revealed a robust elevation of phosphoenolpyruvate, phosphoglycerates, phospholipids, and ceramides caused by ChREBP deletion in FBP1-deficient liver. Put together, these results suggest that overactivation of ChREBP pathway mediates liver metabolic remodeling in the absence of FBP1, which contributes to the pathogenesis of progressive hepatic steatosis and provides a protection against liver injury. Thus, our findings point to a beneficial role of ChREBP in metabolic remodeling in the context of excessive gluconeogenic intermediates.NEW & NOTEWORTHY FBP1 deficiency in adulthood causes progressive hepatic steatosis due to the overactivation of ChREBP pathway, which enhances lipid synthesis and inhibits fat oxidation. ChREBP-mediated metabolic remodeling protects against liver injury caused by energy deficit and oxidative stress in FBP1-deficient liver.",

Our findings show dysregulation of plasma metabolomic profiles in adolescents and young adults with endometriosis, revealing systemic elevation of fatty acyls and ceramides in endometriosis cases compared to controls. Endometriosis is a gynecologic disease often presenting with severe pelvic pain impacting around 200 million reproductive-aged women worldwide. However, little is known about the pathophysiology and molecular features of endometriosis diagnosed during adolescence and young adulthood. We conducted a cross-sectional analysis including 190 laparoscopically confirmed endometriosis cases and 120 controls who participated in The Women's Health Study: From Adolescence to Adulthood, which enrolled participants from 2012 to 2018. Control participants were females without a diagnosis of endometriosis enrolled from the same clinics as the cases or recruited from the general population. Among the cases, 81 had blood samples collected before and after surgery. Plasma metabolites were measured in blood collected at enrollment using liquid chromatography-tandem mass spectrometry, and a total of 430 known metabolites were evaluated in our analysis. We used linear regression adjusting for age at blood draw, BMI, hormone use, and fasting status at blood draw. Metabolite set enrichment analysis (MSEA) was used to identify metabolite classes. Number of effective tests (NEF) and false discovery rate (FDR) were used for multiple testing correction. The median age was 17\u2009years for endometriosis cases and 22\u2009years for controls. The majority of endometriosis cases had rASRM stage I or II (>95%). We identified 63 plasma metabolites associated with endometriosis (NEF\u2009<\u20090.05). Endometriosis cases had higher levels of plasma metabolites associated with proinflammatory response [e.g. eicosatrienoic acid (\u03b2\u2009=\u20090.61, 95% CI\u2009=\u20090.37, 0.86)], increased oxidative stress response [e.g. xanthine (\u03b2\u2009=\u20090.64, 95% CI\u2009=\u20090.39, 0.88)], and downregulation of metabolites related to apoptosis [glycocholic acid (\u03b2 = -0.80, 95% CI = -1.04, -0.56)]. MSEA revealed increased fatty acyls (FDR\u2009=\u20092.3e-4) and ceramides (FDR\u2009=\u20096.0e-3) and decreased steroids and steroid derivatives (FDR\u2009=\u20091.3e-4) in endometriosis cases compared to controls. When we examined the changes in plasma metabolite profiles before and after surgery among endometriosis cases, 55 endometriosis-associated metabolites significantly changed from before to after surgery. MSEA revealed steroids and steroid derivatives (FDR\u2009=\u20098.1e-4) significantly increased after surgery, while fatty acyls (FDR\u2009=\u20091.2e-4) significantly decreased after surgery. Ceramides did not change from pre- to post-surgery and were elevated in post-surgical blood compared to controls (FDR\u2009=\u20093.9e-3). Our study population mainly consists of self-reported non-Hispanic, white individuals and endometriosis cases with superficial peritoneal lesions only, so the generalizability may be limited. Furthermore, despite our large study population of adolescents and young adults with endometriosis, sample size was limited to conduct detailed stratified analyses of plasma metabolomic profiles, especially by post-surgical pelvic pain outcomes. Our study includes the utilization of state-of-the-art metabolomics technology with high reproducibility to comprehensively investigate the metabolites that were associated with endometriosis diagnosed in adolescents and young adults. Our results suggest a positive impact of endometriosis-related surgery for some, but not all, on systemic metabolic dysregulation in young patients with endometriosis. These results warrant further investigation on whether and how persistent systemic changes despite treatment may lead to long-term chronic disease risk among those diagnosed with endometriosis.

We sought to identify phenotypes (metabotypes) in children with moderate to severe asthma through integrative fecal and serum metabolome analysis. Children from the Systems Pharmacology Approach to Uncontrolled Pediatric Asthma cohort with Global Initiative for Asthma treatment step 3 or higher were recruited. Asthma control was defined by the Asthma Control Test and annual exacerbation history. Targeted metabolomic profiling of feces and serum was performed using liquid chromatography and flow injection electrospray ionization-triple quadrupole mass spectrometry. Similarity network fusion integrated fecal and serum metabolome profiles, followed by spectral clustering. Clusters were analyzed for differences in asthma characteristics, food diaries, fecal microbiota composition, and levels of serum inflammatory markers and blood cells. Integrative fecal and serum metabolome analysis of 92 children with moderate to severe asthma (median age, 11.5 years, 34% female) revealed 3 metabotypes. Metabotype 1 had the lowest percentage of allergic rhinitis, with elevated serum ceramides and triglycerides. Metabotype 2 had higher odds of asthma control, the highest percentage of children with 4 or more months of breast-feeding, reduced sugar intake, lowest levels of blood neutrophils and serum inflammatory markers, and elevated serum acylcarnitines and \u03c9-3 fatty acids. Metabotype 3 included the highest percentage of uncontrolled asthma patients, with decreased serum cholesteryl esters, phosphatidylcholines, and sphingomyelins, elevated fecal amino acids, and reduced fecal microbiota diversity. Metabotypes in children with moderate to severe asthma are linked to asthma control, distinct fecal microbiota, and systemic inflammatory patterns. The findings suggest that metabotyping can be valuable in precision medicine approaches for asthma.",

However, the mechanism responsible for this nutrient-sensing process is ill-defined. Here, we show that Nogo-A, encoded by reticulon 4 (Rtn4) gene and associated with brain development and synaptic plasticity, regulates feeding and energy metabolism by controlling lipid metabolism in Agouti-related protein (AgRP) neurons. Nogo-A expression was upregulated in AgRP neurons of fasted mice and was associated with a significant downregulation of enzymes involved in sphingolipid de novo biosynthesis and the upregulation of key enzymes in intracellular lipid transport and fatty acid oxidation. Deletion of Rtn4 in AgRP neurons reduced body weight, ghrelin-induced AgRP activity and food intake, and fasting-induced AgRP activation, together with an increase in ceramide levels. Finally, high-fat-diet-induced obesity induced a significant downregulation of Rtn4 and increased ceramide levels in AgRP neurons, suggesting a role for Nogo in AgRP dysregulation in obesity. Taken together, our data reveal that Nogo-A drives AgRP neuronal activity and associated feeding behavior by controlling mitochondrial function and cellular lipid metabolism.",

Their unique metabolic properties include increased glycolysis and oxidative phosphorylation. We combined transcriptomic, metabolomic, and lipidomic analyses to dissect the metabolic dynamics of Tregs upon activation. Combined metabolomic and lipidomic analyses showed that freshly isolated and activated Tregs had distinct metabolomic and lipidomic properties, respectively. Compared with activated effector T cells (Teffs), activated Tregs contained omega-3 long-chain polyunsaturated fatty acid (PUFA)-rich diglycerides and triglycerides. These were supported by transcriptomics data, showing upregulation of PPAR-alpha and PPAR-gamma. Compared with activated Teffs, activated Tregs exhibited greater ceramide production, consistent with the upregulation of ceramide synthase and sphingomyelin synthase. Confocal microscopy revealed that Tregs, in contrast to Teffs, were enriched in lysosomes and peroxisomes upon activation. Our data confirm the unique metabolic properties of Tregs, especially those characterized by omega-3 long-chain PUFA-rich triglycerides and ceramides, together with enriched lysosomes and peroxisomes, which correspond to metabolic alterations.",

In a 12-week intervention involving obese individuals, fasting serum triglyceride levels were significantly reduced in the DAG group compared to baseline. Within-group reductions in triglycerides and low-density lipoprotein (LDL) cholesterol were more pronounced in the DAG group than in the triacylglycerol (TAG) control group (p\u2009<\u20090.05). In a high-fat diet-induced obese mouse model, DAG significantly lowered serum total cholesterol, LDL levels, visceral fat weight (p\u2009<\u20090.05), attenuated hepatic steatosis, and altered hepatic lipid distribution. Lipidomic profiling revealed that DAG markedly downregulated hepatic triglycerides, ceramides, and monoacylglycerols, while normalizing sterol lipid levels. Pathway analyses based on differential lipids showed that DAG affected hepatic lipid composition mainly by intervening in the glycerophospholipid metabolism pathway. Mechanistically, DAG suppressed the expression of stearoyl-CoA desaturase 1 and fatty acid synthase, while upregulating carnitine palmitoyltransferase 1, thereby enhancing hepatic lipid metabolism through dual regulation: inhibition of synthesis and promotion of catabolism and oxidation. These findings reveal DAG's structure-dependent role in restoring lipid homeostasis and provide a theoretical foundation for functional lipid-based strategies targeting metabolic disorders.",

Preclinical and clinical advances have documented that altered energy homeostasis and mitochondria dysfunction is a hallmark of neurological disorders. Diet-derived ceramides species might target and disrupt mitochondria function leading to defective energy balance and neurodegeneration. Ceramides as bioactive lipid species affect mitochondria function by several mechanism including changes in membrane chemical composition, inhibition of the respiratory chain, ROS overproduction and oxidative stress, and also by activating mitophagy. Promising avenues of intervention has documented that intermittent fasting (IF) is able to benefit and set proper energy metabolism. IF is an eating protocol that involves alternating periods of fasting with periods of eating which modulate ceramide metabolism and mitochondria function in neurons.

Eight weeks of PEMF treatment (10 min/week) enhanced PGC-1\u03b1-associated mitochondrial and metabolic gene expression in white and brown adipose to a greater degree than eight weeks of exercise (30-40 min/week). FMT from PEMF-treated donor mice recapitulated these adipogenic adaptations in HFD-fed recipient mice more faithfully than FMT from exercised donors. Direct PEMF treatment altered hepatic phospholipid composition, reducing long-chain ceramides (C16:0) and increasing very long-chain ceramides (C24:0), which could be transferred to PEMF-FMT recipient mice. FMT from PEMF-treated mice was also more effective at recovering glucose tolerance than FMT from exercised mice. PEMF treatment also enhanced bone density in both donor and HFD recipient mice. The gut Firmicutes/Bacteroidetes (F/B) ratio was lowest in both the directly PEMF-exposed and PEMF-FMT recipient mouse groups, consistent with a leaner phenotype. PEMF treatment, either directly applied or via FMT, enhanced adipose thermogenesis, ceramide levels, bone density, hepatic lipids, F/B ratio, and inflammatory blood biomarkers more than exercise. PEMF therapy may represent a non-invasive and non-strenuous method to ameliorate metabolic disorders.",

To examine the association of plasma sphingolipids with glycemic measures in adults without diabetes. Plasma sphingolipid species (ceramides, monohexosyl ceramides, lactosyl ceramides, sphingomyelins, and sphingosines) were assayed using liquid chromatography tandem mass spectrometry in baseline specimens obtained from participants in the Pathobiology of Prediabetes in a Biracial Cohort study (n = 240) and the Diabetes Prevention Program (n = 280). Based on oral glucose tolerance tests, we identified participants with (1) normal fasting plasma glucose (NFG) (<100\u2005mg/dL) and normal glucose tolerance (NGT) [2-hour plasma glucose (2hPG) < 140\u2005mg/dL]; (2) impaired fasting glucose (IFG; 100-125\u2005mg/dL) with normal 2hPG; (3) impaired glucose tolerance (IGT) (2hPG 140-199\u2005mg/dL with NFG); and (4) IFG and IGT. The participants (63% female; 48% Black, 52% White) had a mean age of 45.5 \u00b1 9.84\u2005years, body mass index (BMI) 32.4 \u00b1 7.24\u2005kg/m2, fasting plasma glucose (FPG) 99.8 \u00b1 10.5\u2005mg/dL, and 2hPG 145 \u00b1 29.4\u2005mg/dL. FPG and 2hPG levels correlated positively with ceramides, sphingomyelins, and sphingosine and inversely with monohexosyl ceramides, lactosyl ceramides, and sphingosine-1 phosphate levels, adjusted for age, sex, race, and BMI. Plasma ceramides, sphingomyelins, and sphingosine increased progressively across participants with NFG-NGT, isolated IGT, and IFG-IGT, whereas the opposite was seen for monohexosyl ceramides, lactosyl ceramides, and sphingosine-1 phosphate levels (ANOVA P < .0001). Circulating levels of major sphingolipid species are significantly associated with glycemia and glucose tolerance, indicating a possible link between sphingolipid metabolism and glucoregulation in people without diabetes.",

Here, we examined the association of plasma sphingolipids with insulin sensitivity and secretion in people without diabetes. We enrolled adults without diabetes based on 75-g oral glucose tolerance test. Assessments included clinical examination, insulin sensitivity (hyperinsulinemic euglycemic clamp), and insulin secretion (intravenous glucose tolerance test). Plasma levels of 58 sphingolipid species (including ceramides, monohexosylceramides, sphingomyelins, and sphingosine) were assayed using liquid chromatography tandem mass spectrometry. The study participants (N = 240; 129 Black, 111 White) had a mean age of 43.1 \u00b1 12.0\u00a0y, body mass index (BMI) 29.4 \u00b1 6.23\u00a0kg/m2, fasting plasma glucose 91.4 \u00b1 6.91\u00a0mg/dL, and 2-h plasma glucose 123 \u00b1 26.3\u00a0mg/dL. Several of the 58 SPLs species assayed showed variable associations with insulin sensitivity (r = 0.17-0.35, P = 0.039 - <0.0001) and secretion (r = 0.14-0.27; P = 0.038 - <0.0001). After correction for multiple testing, plasma levels of very-long-chain (VLC) monohexosylceramide C34:0 (r = 0.31 - 0.43, P < 0.0001) and VLC sphingomyelins C28-C34 (r = 0.31-0.35, P = 0.0004 - <0.0001) were significantly associated with insulin sensitivity. Plasma VLC sphingomyelin level were inversely associated with insulin secretion, plasma glucose, BMI, and waist circumference. We conclude that circulating VLC sphingomyelins are associated positively with insulin action and inversely with insulin secretion and adiposity in normoglycemic adults, indicating a possible link to glucoregulation that precedes the development of dysglycemia.",

Experimental models as well as epidemiological observations support the hypothesis of a role of diet in the disease onset, activity, and progression. It has been suggested that Western-type diets might be detrimental, while on the other hand, certain dietary regimens, like Mediterranean, low-fat, ketogenic, or intermittent fasting, might lead to disease amelioration, possibly through differential regulatory effects upon inflammation, immunity, and regenerative processes of neurons and glia. Under this perspective, immunometabolites, small intermediates including among the others citrate, itaconate, lactate, glutamate, glutamine, alfa-ketoglutarate, 2-hydroxyglutarate, fumarate, ceramides, whose turn-over reflects metabolic reprogramming of immune cells, might be viewed as significant regulators of cellular responses against either local or systemic noxious stimuli, both in the periphery and in the CNS. The present narrative review aims at summarizing current experimental and clinical evidence regarding the role of immunometabolites in shaping MS pathology, to address whether they could be relevant either as disease markers or therapeutic targets, and whether they might be differentially influenced by dietary approaches, especially by Mediterranean Pattern Diets (MPD).",
"40849529": "ID: 40849529\nTitle: Characterizing plasma lipid species in metabolic dysfunction associated steatotic liver disease in persons with type 1 diabetes.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) is the hepatic manifestation of metabolic syndrome. Hepatic lipotoxicity and inflammation are two key factors driving progression of steatosis to metabolic dysfunction-associated steatohepatitis (MASH). The presence of MASH increases the risk of cardiovascular events, cirrhosis, hepatocellular carcinoma (HCC) and non-liver malignancies. Although MASLD and lipid species have been extensively examined in persons with type 2 diabetes, much less is known in type 1 diabetes. We examined the association of key lipid species with MASLD in individuals with type 1 diabetes. We designed a cross-sectional study of 30 participants with type 1 diabetes recr1uited from our institutional diabetes clinics. All participants had fasting blood drawn for targeted lipidomics and underwent a FibroScan. Those with steatosis score of\u2009\u2265\u2009248 as determined by controlled attenuation parameter (CAP) were categorized as cases (n\u2009=\u200917); those with steatosis score\u2009<\u2009248 were categorized as controls (n\u2009=\u200913). BMI was significantly higher in cases than controls (P\u2009=\u20090.0007) and used significantly higher 24-h insulin doses than controls (P\u2009=\u20090.004). Cases displayed significantly higher circulating levels of total ceramides (P\u2009=\u20090.02), diacylglycerols (P\u2009=\u20090.0009) and triacylglycerols (P\u2009=\u20090.0004). The two groups displayed similar levels of hexosylceramides, dihydrosphingomyelins, sphingomyelins, and phosphatidylcholines. Similar to previous findings, numerous sphingolipids species, diacylglycerols, and triacylglycerols were found to correlate positively with higher BMI and 24-h insulin dose. Total circulating dihydroceramides, ceramides, diacylglycerols, and triacylglycerols levels significantly correlated with steatosis score (P\u2009<\u20090.05). None of the lipid species correlated with fibrosis score. These results suggest that persons with type 1 diabetes and MASLD have a higher BMI, are likely to be insulin resistant, and display elevated circulating levels of dihydroceramides, ceramides, diacylglycerols, and triacylglycerols, which are strongly associated with the pathogenesis of steatotic liver disease.",

Out of 90 subjects (age 46.7 \u00b1 10.5 years; body mass index of 32.0 \u00b1 6.3 kg/m2) who underwent a 2-hour OGTT, 19 had normal glucose tolerance, 22 had 1-hour plasma glucose \u22658.6 mmol/L (1hrOGTT), and 49 had 2-hour >8.6 and \u226410 mmol/L (impaired glucose tolerance). Homeostatic model assessment of insulin resistance (HOMA-IR) was determined for each group and was subdivided into 2 subgroups (HOMA-IR <2.5 or \u22652.5). Areas under the curve (AUCs) for glucose, insulin, C-peptide, and triglycerides were calculated during the OGTT. Ceramides were assessed by liquid chromatography-mass spectrometry on a fasting blood sample. There was no significant difference across the glucose tolerance groups, as well as the subgroups depending on HOMA-IR, for all evaluated lipid markers and ratios. The AUCC-peptide was positively associated with C16 (r = 0.21, P = .051), while a negative relationship was apparent between the insulin secretion-sensitivity index-2 and C24 (r = -0.21, P = .051), HOMA-IR \u22652.5 and the C16/24 (r = -0.22, P = .034), C18/24 (r = -0.22, P = .037), and C24:1/C24 (r = -0.24, P = .022) ratios. Our results demonstrate diminished C16/C24 and C18/C24 ratios in subjects with insulin resistance, and an independent relationship between C16:0 ceramide and stimulated insulinemia, and between C16 and C18 and kidney function, highlighting the leading role of specific ceramide subspecies rather than the overall ceramide levels for the cardiometabolic profile in early stages of glucose intolerance.",
"41002985": "ID: 41002985\nTitle: Impact of Dietary Interventions on the Human Plasma and Lipoprotein Lipidome.\nAbstract: Lipids are structurally diverse biomolecules that play essential roles in cellular function, energy storage, and signaling. The human lipidome, a dynamic and complex subset of the metabolome, is shaped by both endogenous factors, such as genetics, sex, age, and metabolic health, and exogenous influences like lifestyle, diet, and microbiota. Among these, diet stands out as one of the most modifiable and impactful determinants, influencing lipid composition across plasma, serum, and lipoprotein fractions. While traditional lipid profiling provides limited insight, lipidomics enables comprehensive characterization of lipid species, revealing mechanistic links between lipid metabolism and diseases such as cardiovascular disease (CVD), metabolic syndrome (MetS), and inflammatory disorders. This review explores: (1) the relationship between lipid profiles and CVD risk, (2) the internal and external modulators of the lipidome, and (3) current evidence on how specific dietary patterns, including Mediterranean, Nordic, low glycemic, and vegetarian diets, and individual nutrients such as omega-3 fatty acids (FAs), plant sterols, and mycoprotein, influence lipidomic profiles. Advances in lipidomics highlight that dietary fat quality, food matrix, and eating patterns can significantly modulate lipid species such as triacylglycerols (TAGs), ceramides (Cers), and phospholipids, with implications for cardiometabolic health. Notably, distinct responses are observed across plasma High-Density Lipoprotein (HDL) and Low-Density Lipoprotein (LDL) lipidomes, emphasizing the need for compartment-specific analyses. Understanding these diet-lipidome interactions offers promising avenues for precision nutrition and the development of lipid-based biomarkers for disease prevention and management.",
"41033655": "ID: 41033655\nTitle: Evaluation of the effects of metformin on gut functions and microbiota and their contribution to improving glucose tolerance in diabetic mice.\nAbstract: Although the mechanism of action of the antidiabetic drug metformin is still a matter of discussions, increasing evidence points to a pivotal role of the gut. Aiming to clarify whether metformin-induced changes in the intestinal tract directly contribute to metabolic improvement, we evaluated the effects of escalating doses (from 50 to 200 mg/kg/day) of metformin orally administered for 4 weeks in mice made glucose intolerant by ten weeks of high fat high sucrose diet. Several intestinal parameters were studied, including caecal microbiota composition and bile acids profile, ileal FXR signaling, abundance of GLP1-producing cells and goblet cells and blood metabolome. Metformin restored glucose tolerance, fasting insulinemia and HOMA-IR index in a dose-dependent manner. Only a subset of gut-related effects, including mucus production and GLP-1 expression, exhibited a parallel dose-response relationship, suggesting a possible contribution to the observed metabolic improvements. In contrast, other changes, including ileal Fxr-Fgf15 inhibition and hepatic ceramide reduction did not scale with dose, suggesting they are not the main drivers of metformin dose-dependent effects on glycemic control. We also pointed out marked differential sensitivity of gut bacteria to metformin supporting complex interactions of the drug with the microbial ecosystem. Finally, metformin enhanced the proliferation of intestinal epithelium, resulting in increased length of ileal villi. Altogether, this study offers new insights into the metformin mechanism of action and revealed potential novel microbial biomarkers and targets for enhancing its therapeutic efficacy.",

The discovery cohort consisted of 50 prepubertal children, including 30 children with obesity and 20 lean. The validation cohort included 25 children with obesity and IR (obese-IR) and 25 children with obesity without IR (obese-NIR). Fasting plasma was collected from all participants for Olink proteomics and untargeted lipidomics. Pearson correlation analysis was used to identify proteins and lipids associated with IR, and area under the receiver operating characteristic (AUROC) was applied to compare the ability of the identified proteins and lipids with traditional indices in the diagnosis of IR. In the discovery cohort, a total of 15 lipids and 10 proteins had significant correlation with IR. In the validation cohort, protein fatty acid binding protein 4 (FABP4) and gene serpin family E member 1 (PAI) were overexpressed in obese-IR children compared to obese-NIR children, while insulin like growth factor binding protein 1 (IGFBP-1) and paraoxonase 3 (PON3) were lower in the IR group than in the obese-NIR group; five lipids including sphingosine (d16:0), coenzyme (Q8), ceramides phosphate (d42:2), phosphatidylethanolamine (37:2e), and phosphatidylcholine (18:1e_16:0), showed significant (p < 0.05) change in obese-IR children compared to obese-NIR children. In addition, the AUC-ROC was 0.89 for IGFBP-1, 0.81 for PON3, and 0.65 for PAI. The ability of IGFBP-1, PON3, and PAI to diagnose IR was better than that of adiponectin and leptin. The AUROC of phosphatidylcholine (18:1e_16:0) and coenzyme (Q8) were 0.80 and 0.73, respectively, which was significantly higher than the AUROC of triglycerides(TGs), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C). Proteomic and lipidomic analysis can allow for the identification of potential new candidate biomarkers for IR. The ability of novel biomarkers to diagnose IR was better than traditional indicators.

We hypothesized that distinct insulin-derived mechanisms and lipid profiles discriminate sex differences and can be used to identify subjects at higher risk to develop diabetes-related complications. The PREVADIAB2 study evaluated metabolic alterations after 5\u2009years in individuals initially free of Type 2 Diabetes (PREVADIAB1). In this analysis, 953 participants were stratified into clusters using hierarchical clustering based on insulinogenic index (IGI), fasting insulin secretion rate, HOMA-IR, and fasting insulin clearance. A subset of participants (n\u2009=\u2009488) had their lipidome assessed using LC/MS-QTOF. Four clusters were identified: Liver Sensitive (LS), Pancreas Glucose Sensitive (PGS), Insulin Deficient (ID), and Insulin Resistant (IR), each with distinct dysglycemia risk. While metabolic features were similar across sexes, the parameter thresholds differed, resulting in sex-specific lipidomic profiles. Women exhibited higher levels of circulating dihydroceramides (5.3\u2009\u00b1\u20091.9 vs. 4.7\u2009\u00b1\u20091.8, p\u2009<\u2009.001), associated with de novo ceramide synthesis, and elevated sphingomyelins (SM), suggesting altered lipid metabolism. Conversely, the ceramide-to-SM ratio was higher in men (1.04\u2009\u00b1\u2009.21 vs. .90\u2009\u00b1\u2009.18, p\u2009<\u2009.001). Except for the LS cluster, all other clusters exhibit distinct lipid signatures associated with metabolic dysfunction, further accentuated by specific lipid profile sex differences. Distinct insulin-related metabolic features and sex identify different phenotypes with distinct lipidome profiles, highlighting the need to place prediabetes in a broader context of metabolism beyond glucose.",

Clustered regularly interspaced short palindromic repeats-Cas9 gene editing technology was used to knock out the ApoB48 gene in C57BL/6J mice, and genotype identification showed heterozygosity (HE, ApoB48 +/-). Subsequently, eight HE and eight wild-type (WT) mice were fed a HFD for 12 weeks. Fasting blood glucose, and insulin levels were decreased in ApoB48 +/- mice. The intraperitoneal glucose tolerance test and intraperitoneal insulin tolerance test showed mild insulin resistance. Moreover, it delayed the development of atherosclerosis and intestinal tissue damage. Differential metabolites such as ceramide, sphingosine, and sphingosine-1-phosphate were identified using liquid chromatography-mass spectrometry, and differentially expressed proteins, including ceramide synthase 6 (CerS6), protein phosphatase 2A (PP2A), and protein kinase B (AKT), were indicated by the Kyoto Encyclopaedia of Genes and Genomes. Therefore, decreased expression of ApoB48 can ameliorate lipid metabolism disorders induced by an HFD, which may be related to the CerS6/PP2A/AKT pathway. This might represent a new approach for exploring methods to treat hyperlipidaemia.",
"41344402": "ID: 41344402\nTitle: Modulation of ceramides through nutrition: A new target in obesity and insulin resistance (Narrative Review).\nAbstract: Ceramides (Cer) are signaling sphingolipids that participate in insulin signaling, mitochondrial integrity, and inflammation. In obesity and insulin resistance (IR), Cer biosynthesis is exacerbated, leading to metabolic dysfunction and chronic diseases. This narrative review synthesizes current evidence on how Cer metabolism can be modulated through dietary components and dietary patterns, with emphasis on lipidomic analyses. The synthesis and accumulation of Cer are influenced by dietary abundance and quality, such as carbohydrates, fat and phenolic compounds. High-fructose corn syrup and saturated fatty acids promote Cer accumulation and IR, while monounsaturated and polyunsaturated fatty acids-abundant in the Mediterranean and Nordic diets-attenuate these effects. Polyphenol-rich foods and caloric restriction may also reduce Cer concentrations and improve metabolic markers. The emerging evidence from lipidomic analyses is expanding our knowledge on the role of diet in Cer modulation. Nutritional strategies targeting ceramide metabolism represent a promising approach to improve metabolic health. Beyond their therapeutic potential, ceramides also emerge as dynamic lipidomic biomarkers capable of reflecting early metabolic changes and monitoring the efficacy of nutritional interventions.",

To map the plasma lipidomic profiles of incident T2D, glycemic traits, and arsenic exposure/metabolism, and to assess the mediating roles of lipids in arsenic-related diabetogenesis. A nested case-control study of 92 incident T2D cases and 184 controls was conducted within an urban adult-based prospective cohort. Plasma lipidome and urinary arsenic species (As3+, As5+, MMA, DMA, and AsB) were measured. Orthogonal partial least squares-discriminant analysis, t-test, and conditional logistic regression were applied to identify T2D-associated lipids, while partial least squares regression, t-test, and linear regression were conducted to identify glycemic traits- and arsenic-associated lipids. Mediation analyses quantified lipid-mediated effects. Several arsenic exposure indicators (tAs, iAs, As3+, As5+, and DMA) were associated with increased T2D incidence (odds ratios [ORs]: 1.37-1.76), whereas metabolism indices (MMA% and primary methylation index [PMI]) showed protective associations with T2D (ORs: 0.59-0.61) and improved glucose homeostasis. We identified 163 T2D-associated lipids, characterized by increased triacylglycerols (TGs) and diacylglycerols (DGs) but reduced lysophosphatidylcholines, sphingomyelins (SMs), and hexosylceramides. Most TGs, DGs, and ceramides (Cers) were positively associated with fasting plasma insulin and HOMA-IR. Arsenic exposure was associated with higher TGs but lower DGs, Cers, and SMs. Efficient arsenic metabolism (higher DMA% and secondary methylation index [SMI]) was positively associated with most lipids, whereas MMA% and iAs% were inversely associated. Mediation analyses revealed 19 (mainly TGs/DGs), 16 (mainly SMs/phosphatidylcholines), and 35 (mainly TGs/Cers) lipids that partially mediated arsenic exposure-T2D, arsenic metabolism-T2D, and arsenic metabolism-insulin resistance associations, respectively, with mediation proportions of 11.4%-54.7%. Arsenic exposure and metabolism are associated with distinct lipidomic profiles that may precede T2D onset.

Recently, increased ceramides and sphingolipids have been implicated in obesity, insulin resistance, and atherogenesis. However, limited data exists on serum Lyso-GL-1 level in children with obesity and its relation with insulin resistance, lipid dysfunction, and atherogenesis. Hence, this study aimed to assess Lyso-GL-1 level among children with obesity and correlate it with biomarkers of insulin resistance and atherogenic index of plasma (AIP). Sixty children with obesity with a mean age of 10.06 years (SDS\u2009\u00b1\u20092.22) and 60 age- and sex-matched normal-weighed controls were assessed for anthropometric measures, mean blood pressure percentiles, serum Lyso-GL-1, glycated hemoglobin (HbA1c), fasting insulin, triglycerides, cholesterol, low-density (LDL-C) and high-density lipoprotein cholesterol (HDL-C) with calculation of the homeostatic model assessment of insulin resistance (HOMA-IR) and the AIP. Children with obesity have significantly higher Lyso-GL-1 and AIP than controls. Lyso-GL-1 is significantly positively correlated with body mass index (BMI) z-score, waist/hip ratio z-score, systolic and diastolic blood pressure percentiles, LDL-C, HOMA-IR, and AIP (p\u2009<\u20090.05), being independently correlated with systolic blood pressure percentile, LDL-C, and AIP on multivariate regression analysis. Serum Lyso-GL-1 is elevated in children with obesity, being closely correlated with hypertension, insulin resistance, and atherogenesis. This could provide a mechanistic insight on the role of Lyso-GL-1 in obesity and atherogenesis. Further studies are warranted to explore the potential role of Lyso-GL-1 as a biomarker and target for the prevention and treatment of obesity-related atherogenesis and insulin resistance.",

Exercise training is an effective intervention to protect against these metabolic changes. However, little is known about the mechanisms underlying the impact of exercise training on lipid metabolism in PLWH. This study aimed to comparatively evaluate the effect of high-intensity functional circuit training on the plasma lipidome of PLWH and HIV-negative subjects (control). PLWH (n = 13) and control (n = 14) were submitted to 8 weeks of exercise training. Body composition, anthropometric, and biochemical parameters were measured. Plasma was obtained in a fasting state for lipidomic analysis. Anthropometric and biochemical parameters revealed lower levels of leptin, HDL-C, body fat %, and BMI combined with elevated aspartate transaminase (AST) and Homeostasis Model Assessment of \u03b2-cell function (HOMA_beta) in PLWH when compared to control subjects that persisted from baseline to post-exercise training. Nonetheless, contrasting levels of adiponectin, fasting insulin, and phosphatidylcholine-containing lipids observed at baseline were equalized after training in PLWH. In control subjects, significant reductions in concentrations of triglycerides alongside phosphatidylinositol and glycosylated ceramides were observed post-exercise training. By contrast, PWLH displayed an increase in diglycerides, acylcarnitines, and free cholesterol levels after exercise training, together with decreased concentrations of free fatty acids, cholesteryl esters, and glycosylated ceramides. In addition to specific lipidome alterations in each group, particularly driven by improved insulin resistance in PLWH, this study showed concomitant modulation of several glycerophospholipids and sphingolipids, suggesting health-promoting effects of short-term exercise training. Collectively, these modulated lipid species represent interesting targets for future lipidomic-based studies evaluating not only the effects of exercise training but also the molecular mechanisms resulting in a healthier plasma lipidome profile.",

Radically different from an energy source or structural component, lipids influence immune cell regulation, signaling and inflammatory responses. This narrative review provides a broad overview of the role lipids play in immune regulation in both healthy and pathogenic states. We initiate the review by summarizing the role of a variety of lipid classes in immune cell biology, with an emphasis on explaining how lipid composition and metabolism influence both innate and adaptive immunity. Next, we analyze the role that lipid-based mediators eicosanoids, resolvins and ceramides play in regulating inflammatory and pro-resolving pathways. We observe dietary and circulatory lipids additionally direct the immune response and modulate the resolution of inflammatory processes. In diseases characterized by prolonged and persistent immune activation and low-grade inflammation, such as atherosclerosis, obesity, type 2 diabetes and autoimmune diseases, impaired lipid metabolism ultimately aids this persistent state of immune activation. Moreover, we also consider the emergent role of the lipid-immune interface in infectious disease, demonstrating ways in which pathogens can hijack or modify lipid metabolism to escape the host immune response. We cover the potential therapeutic implications of lipid-immune interactions, noting potential strategies using statins, omega-3 fatty acids, or specialized lipid mediators, all with the objective of modulating inflammation rather than broad immunosuppression. Finally, we also identify important knowledge gaps and will suggest avenues for future research, particularly the need for more integrated lipidomic and immunologic studies.",

We tested associations between individual lipids and incident diabetes with interval-censored, multivariable-adjusted Cox proportional hazards regression, accounting for multiple comparisons. We used differential expression analysis to identify pathways upregulated and downregulated in participants who developed diabetes over the 15-year period. Finally, we used penalized regression (LASSO) to generate a lipid risk score for incident diabetes (0.7 training, 0.3 testing). In hazards regression, 156 lipids including glycerolipids, glycerophospholipids, and sphingolipids, were associated with incident diabetes. Of these, 56 lipids were also selected by LASSO regression as distinguishing participants who developed diabetes from those who did not. The lipid risk score's ability to improve prediction of 15-year incident diabetes past sociodemographic, behavioral, and clinical covariates was limited to the training set. Pathways leading to diacylglycerols and ceramides were upregulated, while pathways leading to hexosylceramides, lysophosphatidylethanolamines, triacylglycerols, and lysophosphatidylcholines were downregulated in incident diabetes cases. Our results in this cohort of early middle-aged adults, supports further investigation into the roles of glycerophospholipid and sphingolipid metabolism in diabetes development, particularly for ceramides and hexosylceramides.",

Biliopancreatic diversion with duodenal switch (BPD/DS) could significantly improve insulin sensitivity with significantly elevated level of bile acids. We aimed to explore changes in PCOS manifestations after BPD/DS and the possible mechanisms. Twenty PCOS rat models were assigned into the BPD/DS group and the sham BD (S-BPD) group randomly. The fasting blood glucose, bile acids, and ceramides levels in serum samples were assessed. The reproductive disorders of BPD/DS group were almost completely restored 8 weeks after surgery, and the AUCOGTT value and the AUCITT value were statistically less than those of the S-BPD group (P =0.001). The concentration of serum testosterone, luteinizing hormone, and follicle-stimulating hormone of the BPD/DS group was statistically less than that of the S-BPD group (P <0.05). Moreover, high level of bile acids and low level of ceramides were observed in the BPD/DS group (P <0.001). Bile acid sequestrant was given to the BPD/DS group rats for 1 week, the level of bile acids decreased and ceramides increased, the insulin resistance worsened. The AUCOGTT value increased from 818.3 \u00b1 297.3 mmol/L\u00b7min to 1147.9 \u00b1 167.9 mmol/L\u00b7min (P =0.007) and the AUCITT value increased from 525.6 \u00b1 52.3 mmol/L\u00b7min to 577.7 \u00b1 102.9 mmol/L\u00b7min (P =0.023). Our study showed the improvement of insulin resistance in PCOS models after BPD/DS with decreased serum ceramides. The sequestrant of bile acid reversed the improvement of insulin resistance with higher ceramides level.",

Advances in lipidomics and structural enzymology reveal how enzymatic remodeling of phospholipids, sphingolipids, and acyl chains governs insulin receptor organization, PI3K-AKT signaling, and GLUT4 trafficking. Dysregulated lipid flux mediated by factors such as FABP4, ceramides, and diacylglycerols disrupts membrane microdomains, impairs \u03b2-cell function, and promotes hepatic gluconeogenesis and skeletal muscle insulin resistance. Conversely, omega-3 polyunsaturated fatty acids enhance membrane fluidity and anti-inflammatory signaling. Integrating lipid enzymology with metabolic physiology establishes a unified mechanistic framework linking membrane remodeling to insulin responsiveness and diabetes pathogenesis.",

In this study, we used a multidimensional approach using zebrafish (Danio rerio) exposed to an unpredictable chronic stress (UCS) protocol as a model of MDD, to unravel the plasticity of the lipidome in this mental disorder. Behavioral analyses revealed a reduction in sociability and locomotor activity in stressed animals, accompanied by significantly elevated cortisol levels. Fatty acid profiling demonstrated a decrease in n-3 (omega-3) polyunsaturated fatty acids (PUFA) and an increase in n-3 (omega-6) PUFA, which was more evident in the brain than in the muscle. After UCS, lipidomic analysis revealed a remodeling of the brain lipid profile, including the modulation of several phospholipid and sphingolipid species that may impact cell membrane properties and cause neuronal dysfunction. Some of these species have been previously correlated with neuroinflammation and impaired neurotransmission. An increase in plasmalogen phospholipids, well-known endogenous oxidant signaling molecules, suggests a dysregulation of the redox state. In muscle, lipidomic alterations were characterized by elevated levels of acylcarnitines, indicative of altered mitochondrial energy metabolism, and ceramides, well-known pro-inflammatory and pro-apoptotic molecules. This study highlights the relevance of lipidomic plasticity in the pathophysiology of MDD, associated with behavioral effects similar to MDD symptoms.",

A total of 320 AA broilers were separated into four groups and given either a basic diet or diets with 250, 500, or 1000\u00a0mg/kg RIPS for 42\u00a0days. We employed various multi-omics approaches, including serum biochemistry, lipidomics, transcriptomics, and 16S rRNA sequencing, to investigate the underlying mechanisms. The results indicated that 1000\u00a0mg/kg RIPS markedly enhanced meat color, elevated \u03c9-3 and \u03c9-6 polyunsaturated fatty acids, and augmented antioxidant activity in breast muscle. In the 500\u00a0mg/kg and 1000\u00a0mg/kg groups, alanine aminotransferase (ALT) activity was significantly decreased, and triglyceride (TG) levels were significantly reduced in the 1000\u00a0mg/kg group. Lipidomic analysis revealed that in the 1000\u00a0mg/kg group, the accumulation of triglycerides and ceramides in the chicken breast was lower, indicating an optimization of lipid metabolism. Transcriptomic analysis showed that in the ileum, the expression of FABP1 and APOA1 genes was significantly upregulated in the 1000\u00a0mg/kg group, suggesting improved fatty acid transport and cholesterol metabolism. RIPS also significantly improved the gut microbiota, particularly increasing the abundance of g__Actinomarinales and p__DTB120 in the 1000\u00a0mg/kg group, which were positively correlated with antioxidant capacity and meat quality. In summary, RIPS regulates lipid metabolism and antioxidant defense through the \"gut-muscle axis,\" leading to significant improvements in both meat quality and health in broiler chickens. This study emphasizes the potential of plant polysaccharides in animal nutrition and suggests 1000\u00a0mg/kg RIPS as an appropriate supplementation amount.",

The diabetic mice underwent an 8-week dietary intervention of ad libitum (AL) and IF diet. Meibomian gland (MG) proliferative potential, apoptosis, and ductal hyperkeratinization were assessed using immunofluorescence. Gene expression levels were evaluated by Western blot. Lipid accumulation was observed via LipidTox staining. Transmission electron microscopy (TEM) examined intracellular lipids and mitochondrial ultrastructure in acinar cells. Lipidomic and transcriptomic analyses compared MG gene expression and lipid profiles between groups. IF ameliorated diabetes-induced MGD. IF significantly improved diabetic MG proliferation, apoptosis and lipid metabolism imbalance, as well as improved the expression of the genes involved in lipid metabolism. Simultaneously, the results of lipidomics indicated that IF can effectively modify the types and content of lipids, especially ceramides and cholesterol esters. Transcriptomic results suggested that IF effectively ameliorated cell death and modulated ion channels signaling. IF could ameliorate cell death which might be mediated by the calcium ion signaling pathway to mitigate diabetes-induced MGD. These results provide direct evidence for the feasibility of dietary intervention to improve diabetes-induced MGD. IF can alter MG lipid composition and inhibit apoptosis in diabetic condition. The underlying mechanism may be associated with calcium ion signaling pathway.",

Facing the lack of defined research strategy to found and qualify bacterial with real antidiabetic activity, we have developed a program to identify, select and validate novel strains able to improve metabolic alterations in type 2 diabetes. Among potential candidates, we identified Bacteroides faecichinchillae (named BAfa hereafter), and the present work presents the validation of the antidiabetic potential of the ST37 (DSMZ 26883) BAfa strain in mice fed a high-fat high-sucrose (HFS) diet for 10 weeks followed by 4 weeks of treatment. Daily gavage with live, but not heat inactivated, BAfa improved glucose tolerance, fasting hyperinsulinemia and liver triglyceride content in HFS fed mice. Furthermore, these beneficial effects were retained after lyophilization. Using this preclinical model, we characterised BAfa mechanism of action, showing that four weeks of treatment was associated with reduced hepatic accumulation of ceramides, key actors of insulin resistance. The underlying mechanism could be related to BAfa-induced changes in the intestinal bile acid profile and inhibition of the Fxr-Fgf15 pathway in the ileum. BAfa supplementation during 4 weeks in HFS fed mice was also associated with mild modifications of gut microbiota composition, with the upregulation of several species known for their beneficial metabolic actions (such as Lactobacillus johnsonii, Limosilactobacillus reutei, Roseburia, Turicimonas muris, Phocaeicola dorei or Akkermansia muciniphila) and for being up-regulated during metformin treatment. Altogether, these data indicate that BAfa and related B. faecichinchillae strains could be considered for developing next-generation probiotics to treat type 2 diabetes, potentially in combination with the anti-diabetic drug metformin.",
"42154475": "ID: 42154475\nTitle: Effects of Dietary Carbohydrate Amount and Glycemic Index on Blood Lipidomic Signatures and Diurnal Postprandial Glucose Responses: The OmniCarb Trial.\nAbstract: We investigated whether lowering dietary carbohydrate content and glycemic index (GI) levels altered deep lipidomic profiles and whether these changes were associated with improved diurnal postprandial glucose response (PPGR). In the OmniCarb trial, 59 adults completed 5-week controlled feeding interventions (low carbohydrate/low GI vs. high carbohydrate/high GI) and 12-h meal tests. Comprehensive lipidomic profiling was performed to measure lipid species and lipid class-specific fatty acids (FAs) at the end of each intervention. We found that lowering carbohydrate content and GI levels significantly decreased triacylglycerols (TAGs) and phosphatidylcholines, while increasing lactosylceramides and phosphatidylethanolamines (PEs). Of 731 lipid species analyzed, 521 (71%) were significantly modified, including TAGs (n = 398), PEs (n = 45), and ceramides. Of 199 FAs analyzed across and within lipid classes, 89 showed significant changes (false discovery rate-adjusted P < 0.05), including decreases in saturated FAs (total and TAG FA12:0 and FA14:0) and palmitoleic acid and increases in very-long-chain saturated FAs, when lowering carbohydrate and GI levels. Between-diet changes in six total FAs and 17 lipid class-specific FAs were associated with half-day PPGR changes; greater decreases in joint FA score changes were linked to improved PPGRs. Our study suggests the potential importance of dietary carbohydrate-responsive lipidomic signatures in explaining individual variability in half-day PPGRs and may encourage future intervention studies to target these signatures. Carbohydrate diets with high glycemic index (GI) increase postprandial glucose response (PPGR) and diabetes risk; however, the pathways underlying individual variability in diurnal PPGRs to diets differing in carbohydrate content and GI remain unclear. We examined the effect of lowering dietary carbohydrate content and GI levels on comprehensive lipidomic pathways and tested whether these changes were associated with improved half-day PPGRs. Five-week controlled feeding interventions altered multiple lipid species and lipid class-specific fatty acids toward more favorable profiles, and composite fasting blood fatty acid scores derived from comprehensive targeted lipidomic profiling were associated with improved 12-h PPGRs. These lipidomic signatures explain individual variability in PPGRs and provide targets for future intervention studies.",

However, few studies have comprehensively assessed how multiple of these factors are associated with metabolome and lipidome in a single study. We leveraged untargeted metabolomics and lipidomics to determine the associations of frequencies of alcohol and coffee intake, supplement and medication use, with metabolites and lipid species. This study consists of 702 premenopausal women who provided fasting blood samples. Final analysis included 857 metabolites and 828 lipid species. Multivariable linear regression models adjusted for confounders were used to investigate the associations. We corrected for multiple testing using Benjamini-Hochberg false discovery rate (FDR adjusted p-value\u2009<\u20090.01) and Bonferroni correction (Bonferroni-adjusted p-value\u2009<\u200910-\u20095). At FDR p-value\u2009<\u20090.01, the frequency of alcohol intake was associated with the largest number of biomarkers, including 89 lipid species (9 after Bonferroni correction) across several pathways (ceramides, phospatidylcholines, triacylglycerols, and androgenic steroids) and 123 (13 after Bonferroni correction) metabolites. Frequency of coffee intake was associated with 46 metabolites (27 after Bonferroni correction), with the strongest associations observed for quinate, 3-hydroxypyridine sulfate and trigonelline (N'-methylnicotinate). Frequency of multivitamin use was associated with 18 metabolites (6 after Bonferroni correction). Frequency of statin use was associated with 35 lipid species, respectively, but these were not significant after Bonferroni correction. Alcohol, coffee, and multivitamins are associated with several metabolites and lipid species. These findings offer valuable insights into potential biomarkers of exposure and molecular pathways through which these exposures may be associated with health outcomes.",

In addition, genetic ancestry-related single nucleotide variants in ceramide metabolism genes were associated with the time to prostate-specific antigen progression in the Abi Race study. For this report, the authors analyzed ceramide metabolites and their association with response to ARPI treatment in the Abi Race and PANTHER studies. Fasting serum levels were obtained from 22 Black patients and 22 White patients in the Abi Race trial and from 28 Black patients and 37 White patients in the PANTHER trial who were evaluable pretreatment and on treatment. After metabolomic profiling using the Biocrates MxP Quant 500 Kit and liquid chromatography/tandem mass spectrometry quantification of sphingolipids, differences in ceramide metabolites by race and timepoint and associations of ceramide metabolites with outcomes were evaluated. Pretreatment total ceramide levels were lower among Black patients compared with White patients who had mCRPC. Among pretreatment ceramide levels, Black patients had higher C24:C16 ceramide ratios compared with White patients. During ARPI treatment, Black patients had lower C24:C16 ceramide ratios, whereas the majority of C24:C16 ceramide ratios were higher during treatment among White patients. Ceramide metabolites were associated with the time to prostate-specific antigen progression, radiographic progression-free survival, and overall survival among Black and White patients with mCRPC who received ARPI, with higher expression of the ceremide Cer(d18:1/20:0) associated with shorter radiographic progression-free survival and worse overall survival among Black patients who received treatment with apalutamide and abiraterone. This study identified genetic ancestry-concordant ceramide metabolites that were associated with outcomes in patients with mCRPC who received treatment with ARPI from the Abi Race and PANTHER studies (ClinicalTrials.gov identifiers NCT01940276 and NCT03098836, respectively).",

While in vitro assays have advanced our understanding of the molecular mechanisms underlying apoptotic cell clearance, they lack the complexity of the physiological environment. This chapter presents a detailed in vivo approach for assessing efferocytosis by mouse peritoneal macrophages using the intraperitoneal (IP) clearance assay. By administering fluorescently labelled apoptotic Jurkat T cells into the peritoneal cavity, this method enables the quantification of apoptotic cell uptake in a native tissue context, capturing the influence of local immune signals, stromal interactions and systemic factors. This protocol is compatible with genetic and pharmacological manipulations, allowing researchers to investigate how various interventions affect efferocytic capacity. Overall, this approach provides a robust and physiologically relevant framework for studying efferocytosis and its implications in both homeostatic and pathological settings.",

Using data from 43,709 predominantly European-ancestry, middle-aged and older UK Biobank participants, we depict a large-scale atlas of plasma proteomic signatures of seven self-reported sleep traits (sleep duration, chronotype, insomnia symptoms, daytime napping, daytime sleepiness, snoring, and ease of getting up in the morning) and a derived sleep health score. We identify 935 proteins associated with at least one sleep trait, converging on lipid metabolism, immune function and inflammation, cell adhesion, and neurochemical signaling. Leveraging genomic structural equation modeling to define three latent sleep factors, namely circadian preference, daytime sleep burden, and nighttime sleep adequacy, bidirectional Mendelian randomization (MR) identifies one protein (LTA) with robust cis-instrument and strong colocalization support (PP.H4\u2009=\u20090.98) for a putative causal effect on nighttime sleep adequacy. Sixteen additional genetically supported candidate proteins rely primarily on trans-pQTL instruments or weaker colocalization. These genetically supported candidates are prospectively associated with incident cardiovascular disease, stroke, type 2 diabetes, dementia, chronic kidney disease, depression, and mortality over a median 13.6-year follow-up, with the strongest per-SD hazard ratio (HR) associations observed for chronic kidney disease (e.g., BTN2A1: HR\u2009=\u20092.33) and type 2 diabetes (e.g., RBP5: HR\u2009=\u20091.58).

Efferocytosis, an intrinsic regulatory mechanism through which microglia eliminate apoptotic cells, is suppressed because of the local ischaemic and hypoxic microenvironment after spinal cord injury (SCI). In addition, hypoxia and reoxygenation (H/R) trigger mitochondrial respiratory chain electron leakage, leading to the massive generation of mitochondrial reactive oxygen species (mtROS), impairing the energy supply and causing oxidative stress damage in neurons, which induces neuronal apoptosis. Synergistic therapies targeting efferocytosis and neuronal apoptosis are important for recovery after SCI. In this study, by loading celastrol in a layered double hydroxide, a multifunctional nanoparticle, Cel-LDH, was developed to facilitate SCI recovery by concurrently normalizing efferocytosis homeostasis and inhibiting neuronal apoptosis. Cel-LDH composite nanoparticles strongly scavenged ROS and preserved mitochondrial homeostasis, thus regulating apoptosis-related proteins, including Bax and Bcl-2, and effectively inhibiting the apoptotic process of neurons. Furthermore, Cel-LDH nanoparticles promoted autophagy, inhibited the cyclic GMP-AMP (cGAMP) synthase (cGAS)-stimulator of interferon genes (Sting) pathway to modulate the anti-inflammatory phenotypic transformation of microglia, and subsequently restored the efferocytosis homeostasis of microglia, thus suppressing inflammatory cascades and creating favourable microenvironments for the repair of SCI. This approach not only remodels the dysfunctional efferocytosis capacity but also inhibits neuronal apoptosis, providing a new therapeutic strategy for SCI.",

AF4 showed significantly higher total amino acid and phenolic contents and the strongest Fe2+-chelating activity (IC50 = 1.64 \u00b1 0.22 mg/mL, p < 0.05) and was therefore selected for nanoemulsion stabilization. Nanoemulsions exhibited high physical stability with no significant changes in droplet sizes (D3,2 ~77-79 nm), \u03b6-potential (~-18 to -19 mV), and viscosity (~1.2-1.5 cP) (p > 0.05). Dynamic interfacial tension measurements and confocal laser scanning microscopy (CLSM) indicated limited interfacial activity of AF4, with most components remaining in aqueous phase. Compared to the control, AF4 significantly reduced peroxide formation (~100-164 vs. 289-357 meq/kg at Day 4-8, p < 0.05) and partially preserved tocopherols. It also delayed the formation of some volatiles during intermediate stages of storage. However, it was less effective than ethylenediaminetetraacetic acid (EDTA). Increasing the AF4 concentration did not further improve oxidative stability. These findings suggest that antioxidant efficacy depends on composition, interfacial behavior, and spatial distribution. Antioxidants with limited interfacial activity may therefore exhibit different modes of action within emulsified systems.",

Polygonati Rhizoma (PR), a traditional Chinese herb widely consumed as a functional food ingredient, is rich in antioxidant polyphenols and polysaccharides, yet its role in modulating senescence of periodontal ligament stem cells (PDLSCs) remains unclear. This study integrated network pharmacology and experimental validation to elucidate the protective effects and mechanisms of PR against oxidative stress-induced PDLSC senescence. Putative PR components and targets related to periodontitis and aging were collected to construct a protein-protein interaction (PPI) network, from which 21 core targets were predicted. These included key inflammation- and senescence-related proteins such as TP53, RELA (p65), TNF-\u03b1, TGF-\u03b21, IL-6, IL-1\u03b2, CXCL8, and MMP-9. Gene Ontology and KEGG enrichment analyses highlighted pathways involved in cellular senescence, NF-\u03baB signaling, and oxidative stress responses. Molecular docking suggested strong binding affinities between major PR constituents and putative core protein targets. In an in\u00a0vitro oxidative stress-induced PDLSC senescence model, PR-medicated serum, with Metformin as a positive control, significantly reduced intracellular oxidative stress markers, alleviated cell-cycle arrest, and downregulated senescence-associated secretory phenotype (SASP) cytokines. PR showed anti-senescent efficacy comparable to Metformin while exhibiting distinct molecular signatures. These findings indicate that PR exerts multi-component, multi-target modulation of NF-\u03baB-centered inflammatory and senescence pathways in PDLSCs, thereby mitigating oxidative stress-induced cellular aging. As an edible, functional herb, PR may represent a promising dietary adjunct for the prevention and management of periodontitis linked to cellular senescence.",

Yet how these diverse signals are molecularly integrated remains unknown. Here we show that clock, diet, and temperature cues converge on the orphan mitochondrial transporter, SLC25A34, to orchestrate thermogenic cycling of lipid synthesis and oxidation. During sleep, the clock suppresses Slc25a34 transcription through REV-ERB\u03b1. Waking, lipid-rich diets, or cold exposure abolish this repression, allowing lipolytic signals to stimulate Slc25a34 expression via PPAR\u03b1. SLC25A34 then imports oxaloacetate into mitochondria to accelerate the export of substrates used for acetyl-CoA production in the cytosol. This feeds into cytosolic lipid synthesis and transcriptional induction of mitochondrial biogenesis, which collectively promote mitochondrial lipid oxidation. Thus, SLC25A34 confers circadian, dietary, and environmental control of thermogenic metabolism through interorganellar lipid cycling.",

In this study, Wanxi White geese at three reproductive stages (pre-laying, laying, and broody periods) were used to investigate the regulatory roles of circadian clock genes in follicular development. Results showed that follicular growth, serum levels of estradiol (E2), melatonin (MLT), and progesterone (P4) markedly increased during the laying period, whereas a higher number of atretic follicles was observed during the broody period. Correspondingly, expression of steroidogenesis-related genes (CYP11A1, CYP19A1, DHCR24, 3\u03b2-HSD and StAR) and melatonin synthesis-related gene (ASMT-1) was upregulated in the laying periods compared with pre-laying and broody periods. Moreover, expression of clock genes (CLOCK, PER2, CRY1, CRY2, ARNTL2A, EYA3 and NPAS2) was significantly higher in the hypothalamus during the laying period than that in the broody period. Notably, CLOCK, PER2, CRY1, CRY2 and DIO2 exhibited similar expression patterns in the hypothalamus and ovary across the three reproductive stages, suggesting that circadian clock genes may contribute to the coordination of hypothalamic and ovarian functions. In addition, genes involved in lipid metabolism and yolk precursor synthesis were markedly upregulated in both the liver and ovary during the laying period. Overall, the elevated expression of clock genes could play an important role in follicular development, hormone secretion, and the coordinating of hepatic lipid transport and yolk precursor formation, providing a theoretical basis for improving egg production and breeding strategies in Wanxi White geese.",
"42288204": "ID: 42288204\nTitle: Sleep and aging: The role of DNA methylation.\nAbstract: Although its evolutionary origins remain poorly understood, sleep is a highly conserved physiological process crucial to animal life and widely recognized as a major determinant of human healthspan. Sleep disturbances are a major public health concern, particularly among older adults, contributing to impaired cognitive function, chronic disease risk, and reduced quality of life. Age-related sleep disturbances are associated with epigenetic changes, especially altered DNA methylation patterns within genes and regulatory regions involved in circadian rhythms, neuroplasticity, metabolism, and inflammation. Over the past decade, epigenetic clocks, which measure DNA methylation patterns at specific CpG sites, have been used to estimate chronological age, assess biological aging, and predict health outcomes and mortality risk. Using epigenetic clocks and genome-wide methylation studies, emerging evidence has linked sleep disturbances and sleep-disrupting conditions, such as insomnia, obstructive sleep apnea, and shift work, to accelerated biological aging. Sleep-related changes in DNA methylation contribute to epigenetic age acceleration by influencing key aging processes, including inflammation, oxidative stress, telomere maintenance, lipid metabolism, and immune function. However, these methylation alterations might be, at least in part, reversible, highlighting opportunities to develop interventions that improve sleep disturbances and slow biological aging.",

Efficient clearance of apoptotic polymorphonuclear neutrophils (PMNs) by macrophages, a process known as efferocytosis, is essential for resolving inflammation, promoting tissue repair, and restoring immune homeostasis; however, the molecular mechanisms governing this process remain poorly understood. Here, we identify p120-catenin (p120) as a critical regulator of efferocytosis that promotes the resolution of inflammatory lung injury. In alveolar macrophage-depleted mice challenged with endotoxin, intratracheal instillation of p120-deficient macrophages delayed the resolution of PMN infiltration, protein exudation, and lung edema and injury compared with control macrophages. These changes were accompanied by increased levels of TNF-\u03b1 and IL-6, decreased levels of TGF-\u03b2 and IL-10, and a reduced number of macrophages containing apoptotic PMNs in bronchoalveolar lavage fluid. p120 depletion also markedly reduced the phagocytosis of apoptotic PMNs by cultured macrophages. Mechanistically, p120 deficiency decreased the expression of the efferocytic receptors CD36 and Axl and shifted macrophage polarization toward a pro-inflammatory M1 phenotype. Furthermore, apoptotic cells induced the association and co-localization of p120 with peroxisome proliferator-activated receptor-\u03b3 (PPAR\u03b3), whereas p120 deletion markedly reduced PPAR\u03b3 activity in response to apoptotic PMNs. Pharmacologic inhibition of PPAR\u03b3 abolished p120-mediated macrophage efferocytosis and the resolution of lung inflammation. Collectively, these findings establish a central role for p120 in macrophage efferocytosis and inflammatory resolution and suggest that targeting macrophage p120 may represent a novel therapeutic strategy to promote recovery from inflammatory lung injury.",

In recent years, immune checkpoint inhibitors have significantly improved the survival outcomes of some patients with advanced non-small cell lung cancer; however, primary and acquired resistance remain important barriers limiting their clinical efficacy. Research has revealed that structural remodeling of the tumor microenvironment (TME) is one of the key factors involved in immunotherapy resistance. Efferocytosis is an important process by which tumor-associated macrophages clear apoptotic cells. In the lung cancer TME, the high apoptotic cell burden can lead to persistent activation of efferocytosis. Studies have shown that sustained efferocytosis is not merely a process of cellular debris clearance, but can also induce metabolic reprogramming in macrophages, including dysregulated lipid metabolism and enhanced glycolysis, and promote the secretion of immunosuppressive and tissue-repair-related factors. These changes further promote pathological angiogenesis, activation of cancer-associated fibroblasts, and excessive extracellular matrix deposition, thereby driving structural remodeling of the TME and forming an immune-excluded microenvironment characterized by vascular abnormalities and stromal fibrosis. This process restricts effector T-cell infiltration and impairs the efficacy of immune checkpoint inhibitors. This review describes the molecular mechanisms of macrophage efferocytosis in the lung cancer TME, focusing on its regulatory roles in metabolic reprogramming, pathological angiogenesis, and stromal fibrosis, and discusses potential therapeutic strategies targeting efferocytosis-related signaling pathways and TME structural remodeling, aiming to provide new insights into overcoming immunotherapy resistance in lung cancer.\u2029. \u3010\u4e2d\u6587\u9898\u76ee\uff1a\u5de8\u566c\u7ec6\u80de\u80de\u846c\u9a71\u52a8\u80ba\u764c\u5fae\u73af\u5883\u7ed3\u6784\u91cd\u5851\u2029\u4e0e\u8840\u7ba1\u751f\u6210\u7684\u673a\u5236\u53ca\u4e34\u5e8a\u5e72\u9884\u524d\u666f\u3011 \u3010\u4e2d\u6587\u6458\u8981\uff1a\u80ba\u764c\u662f\u5168\u7403\u53d1\u75c5\u7387\u548c\u6b7b\u4ea1\u7387\u5747\u5c45\u9996\u4f4d\u7684\u6076\u6027\u80bf\u7624\u3002\u8fd1\u5e74\u6765\u514d\u75ab\u68c0\u67e5\u70b9\u6291\u5236\u5242\u663e\u8457\u6539\u5584\u4e86\u90e8\u5206\u665a\u671f\u975e\u5c0f\u7ec6\u80de\u80ba\u764c\u60a3\u8005\u7684\u751f\u5b58\u9884\u540e\uff0c\u4f46\u4ecd\u6709\u76f8\u5f53\u6bd4\u4f8b\u60a3\u8005\u5b58\u5728\u539f\u53d1\u6027\u6216\u7ee7\u53d1\u6027\u514d\u75ab\u8010\u836f\u3002\u80bf\u7624\u5fae\u73af\u5883\uff08tumor microenvironment, TME\uff09\u7ed3\u6784\u91cd\u5851\u88ab\u8ba4\u4e3a\u662f\u5f71\u54cd\u514d\u75ab\u6cbb\u7597\u7597\u6548\u7684\u91cd\u8981\u56e0\u7d20\u3002\u80de\u846c\u662f\u80bf\u7624\u76f8\u5173\u5de8\u566c\u7ec6\u80de\uff08tumor-associated macrophages, TAMs\uff09\u6e05\u9664\u51cb\u4ea1\u7ec6\u80de\u7684\u91cd\u8981\u8fc7\u7a0b\uff0c\u5728\u7ef4\u6301\u708e\u75c7\u6d88\u9000\u548c\u7ec4\u7ec7\u7a33\u6001\u7684\u540c\u65f6\uff0c\u53ef\u8bf1\u5bfc\u5de8\u566c\u7ec6\u80de\u53d1\u751f\u663e\u8457\u7684\u4ee3\u8c22\u91cd\u7f16\u7a0b\u53ca\u5206\u6ccc\u8c31\u6539\u53d8\u3002\u6301\u7eed\u6d3b\u5316\u7684\u80de\u846c\u4f5c\u7528\u901a\u8fc7\u8c03\u63a7\u8102\u8d28\u4ee3\u8c22\u548c\u7cd6\u9175\u89e3\u7b49\u4ee3\u8c22\u9014\u5f84\uff0c\u4fc3\u8fdb\u591a\u79cd\u514d\u75ab\u6291\u5236\u53ca\u7ec4\u7ec7\u4fee\u590d\u56e0\u5b50\u7684\u5206\u6ccc\uff0c\u4ece\u800c\u9a71\u52a8\u5f02\u5e38\u8840\u7ba1\u751f\u6210\u3001\u6fc0\u6d3b\u80bf\u7624\u76f8\u5173\u6210\u7ea4\u7ef4\u7ec6\u80de\u5e76\u4fc3\u8fdb\u7ec6\u80de\u5916\u57fa\u8d28\u6c89\u79ef\uff0c\u5bfc\u81f4\u80bf\u7624\u57fa\u8d28\u7ed3\u6784\u91cd\u5851\uff0c\u5f62\u6210\u514d\u75ab\u6392\u65a5\u578bTME\uff0c\u9650\u5236\u6548\u5e94T\u7ec6\u80de\u6d78\u6da6\u5e76\u964d\u4f4e\u514d\u75ab\u6cbb\u7597\u7597\u6548\u3002\u672c\u6587\u7efc\u8ff0\u80de\u846c\u4f5c\u7528\u5728TME\u4e2d\u7684\u5206\u5b50\u673a\u5236\uff0c\u91cd\u70b9\u9610\u8ff0\u5176\u5728\u4ee3\u8c22\u91cd\u7f16\u7a0b\u3001\u8840\u7ba1\u751f\u6210\u5f02\u5e38\u53ca\u57fa\u8d28\u7ea4\u7ef4\u5316\u4e2d\u7684\u4f5c\u7528\uff0c\u5e76\u63a2\u8ba8\u9776\u5411\u80de\u846c\u76f8\u5173\u4fe1\u53f7\u901a\u8def\u53caTME\u7ed3\u6784\u91cd\u5851\u7684\u6f5c\u5728\u6cbb\u7597\u7b56\u7565\uff0c\u5e76\u8fdb\u4e00\u6b65\u63a2\u8ba8\u80de\u846c\u76f8\u5173\u6307\u6807\u5728\u514d\u75ab\u68c0\u67e5\u70b9\u6291\u5236\u5242\u7597\u6548\u9884\u6d4b\u7684\u6f5c\u5728\u4ef7\u503c\uff0c\u4ee5\u671f\u4e3a\u80ba\u764c\u514d\u75ab\u6cbb\u7597\u8010\u836f\u7684\u7cbe\u51c6\u5e72\u9884\u63d0\u4f9b\u65b0\u7684\u7814\u7a76\u601d\u8def\u3002\u2029\u3011 \u3010\u4e2d\u6587\u5173\u952e\u8bcd\uff1a\u80ba\u80bf\u7624\uff1b\u5de8\u566c\u7ec6\u80de\uff1b\u80de\u846c\uff1b\u80bf\u7624\u5fae\u73af\u5883\uff1b\u4ee3\u8c22\u91cd\u7f16\u7a0b\uff1b\u8840\u7ba1\u751f\u6210\u3011.",

However, replication of findings from genome-wide association studies across diverse populations remains limited. In this study, we evaluated 88 previously reported acne-associated variants in 2741 acne cases and 2235 controls from the Singapore/Malaysia Cross-sequential Genetic Epidemiology Study. Two association signals were replicated at Bonferroni-corrected significance: rs1159268 near TGFB2 at 1q41 and rs738409 in the PNPLA3 coding region at 22q13.31, with consistent directions of effect. Functional annotation and transcriptomic evidence supported the involvement of these loci in pathways related to pilosebaceous unit biology, including epithelial differentiation, tissue homeostasis, retinoid regulation, and lipid metabolism. Gene-environment interaction analyses further identified 12 variants whose associations with acne risk were modified by screen-time exposure. These findings suggest that screen-associated exposures may act as contextual modifiers of genetic susceptibility, potentially through lifestyle-related metabolic factors, circadian endocrine regulation, and oxidative stress responses. Together, these findings emphasize the importance of considering environmental exposures alongside genetic susceptibility to refine our understanding of acne pathogenesis.",
"42298408": "ID: 42298408\nTitle: Low temperature-induced profiling of transcription and alternative splicing during seed germination in rice.\nAbstract: Low-temperature germination (LTG) is a critical agronomic trait for direct-seeded rice as it ensures uniform seedling establishment. Alternative splicing (AS), a key post-transcriptional mechanism, plays a crucial role in plant responses to abiotic stresses; however, the specific AS events and mechanisms involved in LTG remain poorly understood. In this study, we conducted RNA-Seq to profile the cold stress response in germinating seeds, and identified 12,558 differentially expressed genes (DEGs) in ZH11 seeds after 24\u00a0h of low\u2011temperature treatment during germination. GO annotation showed enrichment in genes associated with circadian rhythm, MAPK and plant hormone signaling, and metabolic processes including nitrogen metabolism. We also detected 12,494 cold-induced differential alternative splicing (DAS) events across 4,812 genes, primarily exon skipping (SE) and intron retention (RI). Cold-induced DAS genes were associated with lipid metabolism and terpenoid biosynthesis implying functions in metabolic adjustment and stress adaptation under cold stress. Furthermore, we identified several potential key regulators of LTG: genes OsCKLP2 and OsSTPK encoding protein kinase, OsPP2C11 encoding protein phosphatase, and transcription factors OsbHLH034, OsKNA2 and OsEREBP26. This study indicates that alternative splicing is involved in rice germination under cold stress. The findings not only advance the theoretical understanding of AS in LTG but also provide valuable genetic resources for breeding cold-tolerant rice.",

This study evaluated the metabolic benefits and chrono-nutritional potential of the prebiotic fructo-oligosaccharides (FOS) in a mouse model of HFD-induced obesity using 24 hour time-series analysis. FOS supplementation not only reduced weight gain, insulin resistance, and hepatic steatosis, but also restored the diurnal oscillations of key metabolic genes (Srebp1c, Ppar\u03b1) and core circadian clock genes (Bmal1, Clock) in metabolic tissues. Notably, FOS reshaped gut microbiota composition by enriching beneficial genera and was accompanied by improved temporal organization of microbial metabolites, particularly the rhythmic production of short-chain fatty acids (SCFAs). Correlation analyses revealed strong temporal associations between FOS-induced microbial rhythmicity and improved host metabolic parameters. These findings suggest that FOS improves circadian metabolic homeostasis, accompanied by changes in gut microbiota rhythmicity and SCFAs rhythmicity, supporting its potential as a chrono-nutritional strategy in metabolic disorders.",

CLHPs rich in polyunsaturated and \u03c9-3 fatty-acid contents, were evaluated as sustainable raw-meat replacers in emulsion-type chicken sausages. Chicken breast was partially substituted with 0\u223c20% CLHPs. Increasing CLHP incorporation reduced viscoelasticity in raw meat batter as indicated by a decrease in storage modulus (G'), and altered water distribution in cooked meat batters, with LF-NMR T\u2082 relaxometry showing increased bound water and decreased free water. In cooked sausages, excessive CLHP addition (20%) destabilized the emulsion system, resulting in reduced cooking yield and water-holding capacity, together with elevated lipid oxidation (P < 0.05). Textural attributes were concurrently weakened at high substitution levels. CLHP inclusion altered color characteristics by decreasing lightness and increasing redness. Microstructural observations confirmed structural disruption and oil droplet coalescence at high inclusion levels. Overall, CLHP substitution should be limited to 15% to preserve emulsion stability and product quality. This research demonstrated that CLHPs are a novel value-added ingredient derived from broiler by-products. Their appropriate incorporation improved physicochemical properties in emulsified meat systems and provides practical guidance for partial meat replacement. These findings support the development of sustainable meat processing strategies and contribute to the valorization of poultry by-products within a circular food economy.",

In this study, we quantified a total of 749 plasma lipid species at baseline using liquid chromatography-mass spectrometry and performed cross-sectional and longitudinal association analysis of plasma lipidome profiles with longitudinal A/T/N biomarkers for AD in the Alzheimer's Disease Neuroimaging Initiative cohort (N\u2009=\u20091395). We identified several lipid species, classes, and network modules of correlated lipids that were significantly associated with cross-sectional and longitudinal changes of A/T/N biomarkers. Notably, we identified lysoalkylphosphatidylcholine (LPC(O)) as associated with cross-sectional \"A/N\" biomarkers at the lipid species, class, and module levels. Also, Phosphatidylethanolamine (PE) ethers were associated with A/T/N biomarkers in the species level and with \"N\" biomarkers in the class and module levels. GM3 ganglioside showed association with cross-sectional and longitudinal changes of \"N\" biomarkers at the species and class levels. Furthermore, 20 lipid species, out of all 57 species identified as associated with \"less severe\" AD biomarkers, contained docosahexaenoic acid (DHA), indicating that the previously reported beneficial effects of DHA on AD were significant at the central biomarker level. In conclusion, our approach linking peripheral metabolic changes with brain metabolic, structural, and functional states strengthens evidence from previous studies that were performed using only clinical AD diagnosis. Importantly, our study also enabled identification of novel lipids that play potential roles in progression of AD pathophysiology, suggesting dysregulation of lipid metabolic pathways as precursors to AD development and progression.",
"42308879": "ID: 42308879\nTitle: Metabolic impact of exercise timing: Myonectin dynamics in overweight and obese postmenopausal women following high-intensity interval training.\nAbstract: Myonectin is a myokine that regulates lipid metabolism, and levels are often reduced in obesity and insulin resistance. This study examined whether the timing of exercise influences myonectin and metabolic responses to high-intensity interval training in obese postmenopausal women. Fifty-eight sedentary postmenopausal women (body mass index 28-35\u00a0kg/m2) were randomized to high-intensity interval training or a control condition. The exercise group completed two counterbalanced cycling sessions (morning 08:00\u00a0h, evening 18:00\u00a0h). Blood samples were collected at baseline, immediately post-exercise, and 2\u00a0h post-exercise to measure serum myonectin, free fatty acids, glycerol, cortisol, and lipid profiles. High-intensity interval training significantly increased serum myonectin 2\u00a0h post-exercise in both morning and evening sessions (p\u00a0\u2264\u00a00.01). Free fatty acids and glycerol increased (p\u00a0\u2264\u00a00.01), and triglycerides decreased (evening: -4.8%, p\u00a0\u2264\u00a00.01). Evening exercise produced a lower peak heart rate (p\u00a0=\u00a00.042) and perceived exertion (p\u00a0=\u00a00.031) than morning exercise. No significant changes were observed in high-density lipoprotein, low-density lipoprotein, or total cholesterol. A single session of high-intensity interval exercise increased serum myonectin and lipolysis-related markers and reduced triglyceride concentrations in overweight and obese postmenopausal women. The higher 2-h myonectin value after evening exercise appears to reflect a time-specific variation rather than clear evidence of an overall evening-exercise advantage. Longitudinal studies using baseline-adjusted and mechanistic analyses are needed to determine whether acute timing-related differences translate into clinically meaningful adaptations.

"42316289": "ID: 42316289\nTitle: Human adipose-derived mesenchymal stem cells ameliorate Diabetic Kidney Disease by restoring macrophage efferocytosis.\nAbstract: Diabetic Kidney Disease (DKD) is a major complication driven by chronic inflammation and impaired tissue homeostasis. While mesenchymal stem cells (MSCs) show promise, the precise mechanisms by which human adipose-derived MSCs (hASCs) modulate macrophage-mediated resolution of inflammation remain to be fully elucidated. We integrated single-cell RNA sequencing (scRNA-seq) analysis of human DKD kidneys with in vivo evaluations in db/db mice and in vitro co-culture models. We employed transcriptomic and molecular approaches to systematically investigate how hASCs impact macrophage functional states. scRNA-seq revealed a significant dysregulation of phagocytosis and efferocytosis pathways in human DKD macrophages. In vivo, hASCs effectively homed to injured kidneys, improved renal filtration, and attenuated pathological injury. Rather than a simple binary pro-inflammation to anti-inflammatory switch, hASC treatment restored a comprehensive efferocytic program involving multiple functional stages: chemotaxis (GPR132), recognition/engulfment (PARP9, ELMO1, RAC1), and lysosomal digestion/exhaution and polarisation (LAMP1, LIPA, PPAR-\u03b3, ABCA1). This multi-targeted enhancement was accompanied contributed to the efficient clearance of apoptotic cells, reduced renal oxidative stress, and the mitigation of chronic inflammation. Our study systematically delineates the therapeutic benefits of hASCs, suggesting the promotion of macrophage efferocytosis as a significant mechanistic pathway by which hASCs exert their therapeutic effects. Specifically, we demonstrate that hASCs positively regulate key molecular signatures across multiple stages of this process - from \"find-me\" signal (LPC/GPR132) and \"eat-me\" recognition (PS/ELMO1) to lysosomal digestion (LAMP1) and subsequent exhaustion and polarisation (LIPA/PPAR-\u03b3/ABCA1).",
"42317866": "ID: 42317866\nTitle: Chrononutrition and cardiometabolic health: circadian timing as a dimension of precision nutrition.\nAbstract: Cardiometabolic diseases, including obesity, type 2 diabetes mellitus (T2DM), hypertension, and cardiovascular disease (CVD), remain major global health challenges despite widespread adoption of evidence-based dietary guidelines. Traditional nutrition recommendations have largely focused on dietary composition and energy intake, with limited consideration of the timing of food consumption. Growing evidence indicates that metabolic processes are strongly regulated by circadian rhythms, suggesting that when food is consumed may be a critical but underappreciated determinant of cardiometabolic health. Chrononutrition, which examines the interaction between meal timing and the circadian system, has therefore emerged as an important area of research. This narrative review synthesizes human evidence linking chrononutrition to cardiometabolic outcomes, with a focus on obesity, insulin resistance and T2DM, lipid metabolism, and cardiovascular risk. Findings from observational studies, randomized clinical trials, and mechanistic investigations consistently demonstrate that eating later in the biological day or night is associated with impaired postprandial glucose regulation, reduced insulin sensitivity, altered lipid handling, and adverse cardiometabolic profiles, independent of dietary composition and total energy intake. In contrast, eating patterns aligned with endogenous circadian rhythms characterized by earlier energy intake and avoidance of late-night eating appear metabolically favorable. This review further situates chrononutrition within the framework of precision nutrition. While precision nutrition aims to explain interindividual variability in metabolic responses using genetic, metabolic, and microbiome-based approaches, circadian timing is rarely considered. Because metabolic capacity varies across the day-night cycle, failure to account for meal timing, chronotype, and circadian alignment may contribute to unexplained variability in dietary responses. Integrating chrononutrition into precision nutrition frameworks may therefore improve interpretation of metabolic phenotypes and enhance the personalization of dietary strategies. Finally, key research gaps are identified, highlighting the need for long-term, diverse human studies and time-resolved metabolic phenotyping to clarify the role of chrononutrition in cardiometabolic disease prevention.",
"42321866": "ID: 42321866\nTitle: Gut microbiota-associated leucine elevation promotes cold-induced atherosclerotic plaque formation and instability.\nAbstract: Environmental factors such as cold exposure have been increasingly recognized as contributors to atherosclerosis progression, yet the underlying mechanisms linking environmental stress to vascular pathology remain incompletely understood. In particular, the role of the gut microbiota and microbiota-associated metabolites in cold-induced atherosclerosis has not been fully elucidated. A cold exposure model was established in ApoE\u207b/\u207b mice fed a Western diet. Integrated multi-omics analyses were combined with fecal microbiota transplantation (FMT) and mechanistic cellular assays to investigate gut microbiota remodeling, metabolic alterations, and immune regulation during cold-induced atherosclerosis. In this study, we demonstrate that cold exposure accelerates atherosclerotic plaque growth and instability in parallel with pronounced gut microbiota dysbiosis and alterations in host metabolic profiles. FMT combined with metabolomic analyses showed that cold-associated gut microbiota is closely associated with elevated circulating leucine levels, suggesting that cold-induced microbial remodeling may participate in this process by modulating host systemic leucine availability. Mechanistically, increased leucine suppressed the Zic family member 2 (Zic2) in macrophages, leading to reduced expression of growth arrest-specific 6 (Gas6), a key mediator of efferocytosis. Impaired Gas6-dependent efferocytosis resulted in defective clearance of apoptotic cells, heightened vascular inflammation, and increased plaque instability. Importantly, supplementation with Lactobacillus johnsonii, a commensal bacterium depleted under cold exposure, normalized circulating leucine levels, restored Zic2-Gas6 signaling, enhanced macrophage efferocytosis, and attenuated atherosclerotic plaque progression. Conversely, leucine supplementation recapitulated the effects of cold exposure on plaque development and instability. Collectively, these findings identify a previously unrecognized cold-microbiota-leucine-Zic2-Gas6-efferocytosis axis that links environmental stress to atherosclerosis progression. Targeting gut microbial regulation of host systemic leucine levels, including L. johnsonii-based interventions, may represent a promising therapeutic strategy for preventing cold-induced atherosclerotic cardiovascular disease.",
"42323492": "ID: 42323492\nTitle: ERK1/2 activation in anti-inflammatory effects and underlying signaling mechanisms.\nAbstract: ERK1/2 are core components of the MAPK signaling pathway and play a central role in the regulation of inflammation. Although ERK1/2 activation is well established for driving pro-inflammatory responses, accumulating evidence systematically summarized in this review demonstrates that ERK1/2 activation can also exert potent anti-inflammatory and pro-resolving effects. At the cellular level, ERK1/2 activation mediates anti-inflammatory regulation through multiple coordinated mechanisms: It promotes activation-induced cell death in T cells, drives macrophages and microglia toward anti-inflammatory phenotypes while fine-tuning their phagocytic activity, enhances efferocytosis of apoptotic cells by myeloid cells to drive inflammation resolution, inhibits dendritic cell maturation, and induces production of the key anti-inflammatory cytokine IL-10. At the molecular signaling pathway level, ERK1/2 suppresses pro-inflammatory NF-\u03baB activity by stabilizing I\u03baB\u03b1, directly interacting with NF-\u03baB p65 subunit, or activating PPAR\u03b3 in both immune cells and tissue-resident cells. In addition, ERK1/2 exerts anti-inflammatory effects through the Nrf2/HO-1 axis, which negatively regulates NF-\u03baB. Further anti-inflammatory axes include the ERK1/2/CREB pathway and the FPR2/ERK1/2 pro-resolving signaling cascade. Other anti-inflammatory mechanisms include the ERK1/2/sCD14 axis that neutralizes LPS, ERK1/2-induced autophagy, and anti-inflammatory signaling triggered by diverse upstream regulators of ERK1/2. This review systematically consolidates the anti-inflammatory and pro-resolving effects of ERK1/2 activation and the underlying molecular mechanisms involved. These findings provide robust evidence that ERK1/2 activation can promote anti-inflammatory and inflammation-resolving responses and refine our understanding of the dual role of ERK1/2 as a \"double-edged sword\" in the regulation of inflammation.",

This study explored the impact of five polyphenols (caffeic acid, curcumin, ellagic acid, quercetin, and resveratrol) added at 0.05%, 0.1%, and 0.2% (w/w) on oxidative reactions, precursor availability, PhIP formation, and quality characteristics of chicken meat cooked by pan-frying. Polyphenol incorporation significantly enhanced moisture retention and lowered cooking loss in the samples with quercetin added at 0.2%. Color analysis showed that most polyphenols increased lightness (L*) while curcumin significantly enhanced yellowness (b*). Redness (a*) decreased for all treatments except quercetin and caffeic acid. All polyphenols reduced the thermal consumption of PhIP precursors (glucose and creatine) with quercetin at 0.2% resulting in residual glucose and creatine levels of 0.83 and 2.08\u00a0mg/g, respectively. Quercetin showed the greatest reduction in lipid oxidation with TBARS inhibition up to 67.79% and the highest decrease in carbonyl content (43.63%). All polyphenols significantly suppressed PhIP formation with quercetin at 0.2% achieving the highest inhibition of PhIP (61.47%), followed by ellagic acid (53.65%), resveratrol (46.15%), and caffeic acid (45.46%) at the same concentration, while curcumin at 0.05% showed the weakest effect (10.25%). The radical scavenging activity of polyphenols did not strongly correlate with their ability to inhibit PhIP formation; correlation analysis revealed that PhIP inhibition was strongly correlated with the extent of lipid and protein oxidation. These findings suggest that dietary polyphenols can reduce PhIP formation in fried chicken patties.",

Efferocytosis, the phagocytic clearance of apoptotic cells by macrophages and dendritic cells, is essential for inflammation resolution and tissue repair. Defective efferocytosis has been increasingly implicated in the progression of diabetes and several of its major complications, including atherosclerosis, nephropathy, retinopathy, impaired wound healing, and osteoporosis. This narrative review is prepared through a focused literature search of studies investigating efferocytosis in diabetes, elucidates how its disruption contributes to the progression of diabetic complications, and further highlight emerging therapeutic strategies aimed at regulating efferocytosis. This paper is expected to provide direction and outlook for the research on efferocytosis and diabetes. Efferocytosis regulation involves a coordinated cascade of find-me signals, engulfment receptors, intracellular cytoskeletal remodeling, and metabolic reprogramming. This review summarizes the key molecular changes of defective efferocytosis and pathological changes in diabetic complications. Importantly, emerging preclinical studies have demonstrated that restoring efferocytosis ameliorate inflammation, promote tissue regeneration, and interrupt the progression of diabetic complications. Efferocytosis not only illuminates fundamental aspects of immune regulation but also opens up new therapeutic possibilities. As the field continues to evolve, integrating efferocytosis-based interventions into the broader therapeutic landscape of diabetes may represent a paradigm shift in the management of its chronic complications.",
"42334420": "ID: 42334420\nTitle: Bile acid retention in efferocytic macrophages shapes their inflammatory status during cholangitis.\nAbstract: The clearance of apoptotic cells by phagocytes is crucial for restoring tissue balance after injury. In autoimmune liver diseases like primary sclerosing cholangitis, cell death is thought to result from accumulation of toxic bile acids within parenchymal cells. Whether, in this context, bile acid-loaded dying cells impact the efficiency of phagocytic macrophages in restoring tissue balance remains unknown. Here, we demonstrate that in a murine model of cholangitis, bile acids accumulate in a subpopulation of efferocytic macrophages with pro-inflammatory features. Our in vitro results indicate that, upon their engulfment, apoptotic hepatocytes laden with bile acids can serve as Trojan horses, delivering bile acids into efferocytic macrophages and thereby shaping macrophage function. This contrasts with the characteristics of macrophages that engulf apoptotic parenchymal cells lacking bile acids. Together, our findings delineate a system in which the content of the phagocytosed dying cells, specifically bile acid-laden hepatocytes, drives a pro-inflammatory program in the corresponding efferocytic macrophages, potentially contributing to chronic hepatic inflammation.",

(sweet potato) leaves: bioactive compounds, cellular pathways, and functional food applications.\nAbstract: The global increase in life expectancy has intensified the need for effective dietary strategies to modulate biological aging and mitigate age-associated functional decline. Plant-derived bioactives have emerged as key regulators of aging-related molecular pathways; however, the anti-aging potential of sweet potato (Ipomoea batatas L. Lam.) leaves (SPL), a nutrient-dense yet underutilized leafy vegetable, remains insufficiently studied. This review aims to systematically evaluate the phytochemical composition, biological activities, and molecular mechanisms through which SPL bioactives influence the major hallmarks of aging. To our knowledge, this is the first comprehensive synthesis specifically focusing on the anti-aging mechanisms of SPL. Evidence from in vitro, in vivo, and emerging human studies demonstrates that SPL bioactives exert multi-targeted effects on oxidative stress, chronic inflammation, mitochondrial dysfunction, protein glycation, and cellular senescence. Mechanistically, SPL polyphenols activate the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway to enhance endogenous antioxidant defenses, while suppressing nuclear factor kappa B (NF-\u03baB)-mediated inflammatory signaling. Additional pathways include inhibition of advanced glycation end-product formation, AMP-Activated Protein Kinase (AMPK)-mediated mitochondrial biogenesis, preservation of telomere integrity, and protection of extracellular matrix homeostasis through modulation of matrix metalloproteinases and collagen synthesis. Collectively, these findings position SPL as a promising functional food candidate for healthy aging. However, clinical validation remains limited. Future research should prioritize randomized controlled trials, dose-response and bioavailability studies, and integrative omics-based approaches to confirm efficacy and facilitate translation into evidence-based functional food applications. Sweet potato leaves (SPL) contain polyphenols with potent anti-aging activity.SPL bioactives activate Nrf2 and suppress NF-\u03baB signaling pathways.SPL compounds regulate oxidative stress and cellular senescence.SPL bioactives promote AMPK-mediated mitochondrial protection.Preclinical studies support metabolic, vascular, and dermal benefits.",
"42346755": "ID: 42346755\nTitle: Time-Dependent Endurance Exercise Improves Metabolic Health Through Circadian Rhythm Regulation in Mice.\nAbstract: Objectives: Circadian rhythms regulate key physiological processes, including metabolism and energy balance. Emerging evidence suggests that the timing of physical activity may influence metabolic outcomes. However, how the timing of endurance exercise impacts long-term metabolic health and the role of the circadian clock in this process remain unclear. This study aimed to investigate whether time-dependent endurance exercise improves metabolic health via circadian rhythm regulation. Methods: A 12-week endurance exercise protocol was established using wild-type (WT) and circadian-disrupted Clock\u039419 mice. Mice were assigned to exercise at Zeitgeber time 0 (ZT0) or Zeitgeber time 0 (ZT12), or to sedentary controls. Assessments included rotarod fatigue test, body weight, epididymal fat ratio, fasting blood glucose, serum triglycerides, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), non-esterified fatty acids (NEFA), intraperitoneal glucose tolerance test (IPGTT), and insulin tolerance test (ITT). Results: Clock\u039419 mice exhibited circadian phase-dependent fatigue susceptibility on the rotarod, particularly at ZT0. Both exercised Clock\u039419 groups (ZT0 and ZT12) showed significant weight reduction compared to sedentary controls, indicating that endurance exercise may counteracts circadian disruption-induced weight gain independent of timing. In WT mice, evening exercise (ZT12) led to enhanced lipid regulation and better glucose tolerance. These time-dependent benefits were absent in Clock\u039419 mutants, demonstrating that the full metabolic advantages of exercise require a functional circadian clock. Notably, endurance training also partially restored serum HDL-C levels in Clock\u039419 mice, suggesting compensatory metabolic responses. Conclusions: Aligning endurance exercise with the body's internal clock provides greater metabolic benefits than untimed exercise. The circadian clock is essential for time-dependent improvements in glucose and lipid metabolism, although some beneficial effects occur independently of a functional clock.",

Fifteen 12-month-old bulls were assigned to three groups: C (control); T1 (40 g/day nano-encapsulated PE from OL); and T2 (400 g/day olive leaf pellets plus 30 g/day micro-encapsulated PE from OMWW) for 40 days. Final body weight and carcass yield were unaffected, although the average daily gain was higher in T2 (p < 0.05). Meat from T2 exhibited lower moisture and higher protein content (p < 0.01) compared with the other groups. T1 showed higher \u03b1-tocopherol levels (p < 0.05). Lipid oxidation was reduced in both treated groups (p < 0.01). Monounsaturated fatty acids tended to decrease in treated groups (p = 0.057), while saturated and polyunsaturated fatty acids (PUFA) were unaffected. However, T2 showed higher total n-3 PUFA (p < 0.05), and a more favourable n-6/n-3 ratio (p < 0.01) was found in treated groups. These results highlight the potential of olive-derived polyphenols as functional feed ingredients to enhance meat quality and promote sustainable, circular livestock systems.",

Alpha-tocopherol (\u03b1-TE) represents the most biologically significant form of VE in vivo. Nevertheless, the potential detrimental effects of \u03b1-TE deficiency on health remain unclear. This study was conducted to investigate the effect of \u03b1-TE deficiency on hepatic metabolism and gut microbiota. Methods C57BL/6J mice were randomly assigned to receive one of three dietary regimens: a \u03b1-TE-deficient diet, a control diet with normal \u03b1-TE, or a high-dose diet containing four times the normal \u03b1-TE level. Histopathology, serum biochemistry, RNA-Seq, RT-qPCR, Western blot, and 16S rRNA gene sequencing with correlation analysis were used to assess metabolic phenotypes, hepatic circadian, hepatic lipid metabolism, and cecal microbiota, respectively. Results The results demonstrated that \u03b1-TE deficiency induced hepatic steatosis and lipid metabolic disturbances. \u03b1-TE deficiency significantly decreased Arntl and Clock expression, but increased Per2. Additionally, it upregulated the expression of lipogenic genes such as Scd1, Elovl6, and Elovl3 and simultaneously downregulated fatty acid oxidation genes such as Cyp4a10, Cyp4a14, and Acot1, bringing about imbalance in lipid homeostasis. In addition, \u03b1-TE deficiency greatly changed the structure and composition of gut microbiota. Bacterial genera like Alistipes, norank_f__Muribaculaceae, Muribaculum, Odoribacter, and Dubosiella were significantly correlated with hepatic circadian and lipid metabolism gene expression with the strongest correlation being Alistipes. Conclusions This work is the first to reveal that short term \u03b1-TE deficiency could cause lipid metabolic disorder via the \"gut microbiota-liver circadian clock\" axis, which provides novel insights into the etiology of nutrition-related metabolic diseases and targets for nutritional intervention.",
"42359775": "ID: 42359775\nTitle: Blue light exposure exacerbates Western diet-induced hepatic lipid accumulation and injury via suppression of the SIRT1-NR1D1 axis.\nAbstract: Excessive exposure to artificial blue light has been associated with circadian disruption and metabolic disorders; however, its role in hepatic lipid metabolism under dietary stress remains poorly defined. This study investigated how blue light exposure modulates Western diet-induced nonalcoholic fatty liver disease (NAFLD) and the underlying molecular mechanisms involving the NR1D1-SIRT1 metabolic axis. Male C57BL/6J mice were fed either a control or Western diet and exposed to blue light or sham illumination for 12 weeks. Hepatic morphology was evaluated by hematoxylin-eosin and Masson's trichrome staining, whereas macrophage infiltration and expression of NR1D1 and SIRT1 were assessed by immunohistochemistry. Untargeted LC-TOFMS-based metabolomic profiling and pathway enrichment analysis were conducted to characterize global metabolic alterations across experimental groups. The results showed that blue light exposure markedly aggravated Western diet-induced hepatic steatosis, ballooning, and lobular inflammation without evidence of fibrosis. Immunohistochemical staining revealed increased F4/80 positive macrophages and downregulation of NR1D1 and SIRT1 in blue light exposed, Western diet-fed (WDBL) mice, suggesting impaired mitochondrial homeostasis. Metabolomic profiling identified 113 hepatic metabolites, revealing distinct clustering by diet and light exposure. Blue light synergistically amplified Western diet-driven accumulation of long-chain and unsaturated acylcarnitines and polyunsaturated fatty acids, indicative of incomplete \u03b2-oxidation and oxidative lipid remodeling. Pathway enrichment analysis highlighted disruptions in glycerophospholipid, sphingolipid and bile acid metabolism, accompanied by reduced antioxidant cofactors (retinol and tocopherols). In conclusion, chronic blue light exposure accelerates Western diet-induced NAFLD progression by suppressing the SIRT1-NR1D1 axis, disrupting mitochondrial lipid oxidation, and promoting redox imbalance and macrophage-mediated inflammation. These findings identify environmental blue light as a metabolic stressor that synergizes with dietary lipid overload to drive hepatic injury, offering new mechanistic insight into light-associated metabolic liver disease.",

Our aim was to investigate differences in the metabolomic and lipidomic profile of autoimmune diseases and to identify pathways linked to beta cell damage. To this end, we compared latent autoimmune diabetes in adults (LADA) and type 1 diabetes, also comparing them with rheumatoid arthritis (RA), a related autoimmune condition, and healthy control participants. Metabolomic and lipidomic analyses were performed for 136 individuals (49 with LADA, 44 with type 1 diabetes, 29 with RA and 14 control participants). Omics of pancreatic islets from healthy donors were also evaluated after in vitro treatment with proinflammatory cytokines. LADA and type 1 diabetes differed from RA in terms of lipidomics and metabolomics. Phosphatidylethanolamines, ceramides, lysophosphatidylcholine and several metabolites at the entry sites of the tricarboxylic acid cycle were higher in type 1 diabetes compared with LADA. In pancreatic islets treated with proinflammatory cytokines, tryptophan concentration was reduced by 80%, indicating the activation of tryptophan metabolism in response to the inflammatory stimulus. In people with autoimmune disorders, kynurenine/tryptophan ratio (Kyn/Trp), a marker of tryptophan pathway activation, was higher than in the control group (Kyn/Trp ratio in control group, median [25th-75th percentile]: 0.014 [0.012-0.019]), with a progressive decline from RA (0.027 [0.022-0.032]) to LADA (0.021 [0.018-0.024]) and then to type 1 diabetes (0.018 [0.014-0.022]), ANCOVA p<0.0001. In LADA, Kyn/Trp was directly associated with fasting C-peptide levels in the multivariate regression model accounting for confounders (p=0.038). Metabolomic and lipidomic profiles differ between LADA and type 1 diabetes and vs RA, providing new insights into the heterogeneity of autoimmune diabetes. Our results confirm the involvement of tryptophan metabolism in autoimmune disorders, suggesting that the impaired activation of this pathway of immune tolerance in LADA is less pronounced than in type 1 diabetes, consistent with its milder degree of beta cell loss.",
"42360622": "ID: 42360622\nTitle: Overview of Novel Mechanisms in Obesity Pharmacotherapy and Implications for Cardiovascular Disease: A Narrative Review.\nAbstract: While nutrient-stimulated hormone (NuSH) therapies (e.g., glucagon-like pepide-1 receptor agonists and dual/triple agonists) have transformed the landscape of obesity pharmacotherapy, the next generation of medications may target body composition optimization or other cardiovascular benefits. This review examines novel obesity mechanisms outside of the NuSH class. Unique mechanisms for obesity treatment include peripherally restricted cannabinoid-1 receptor antagonism, myostatin/activin inhibitors, selective androgen receptor modulators, melanocortin-4 receptor agonism, mitochondrial modulation, thyroid receptor agonists, and fibroblast growth factor analogues. By targeting fat distribution, muscle preservation, inflammatory/oxidative stress pathways, lipid metabolism, and energy expenditure, these agents may improve both the magnitude and quality of weight loss. Early evidence suggests complementary roles alongside NuSH-based therapies for induction, augmentation, and maintenance strategies. Several non-NuSH agents have demonstrated potential in preclinical and early clinical studies to optimize body composition, but additional studies are required to prove large-scale, long-term safety and efficacy.",

Frailty is an emerging public health challenge in aging societies, and age-related magnesium deficiency has been proposed as one contributing factor. We investigated whether aging and cellular senescence impair epithelial magnesium handling in the colon and whether Mallotus japonicus (M. japonicus) leaf extract ameliorates these alterations in mouse colonic epithelial MCE301\u202fcells under senescence-inducing conditions. The mRNA levels of transient receptor potential melastatin 6 (TRPM6) magnesium channel were decreased in the intestines of middle-aged mice and in MCE301\u202fcells after long-term culture or tenovin-6-induced senescence. TRPM6 knockdown, tenovin-6, an inducer of cellular senescence, and low-Mg2+ medium each lowered intracellular free Mg2+ concentration ([Mg2+]i). Low-Mg2+ medium also attenuated proliferation. Transcriptome profiling suggested mitochondrial involvement under Mg2+-limiting conditions, consistent with reduced mitochondrial membrane potential and ATP production as well as increased mitochondrial fragmentation. M. japonicus leaf extract restored TRPM6 expression and [Mg2+]i, improved mitochondrial function, and suppressed senescence-associated secretory phenotype-related gene expression. Among the tested components of M. japonicus leaf extract, geraniin showed the strongest activity and also reduced senescence-associated \u03b2-galactosidase-positive cells, whereas corilagin, mallotinic acid, and mallotusinic acid showed partial effects. We suggest that aging- and senescence-associated TRPM6 downregulation is linked to impaired magnesium homeostasis and mitochondrial dysfunction in colonic epithelial cells. M. japonicus leaf extract and selected ellagitannin-related polyphenols mitigate these senescence-associated alterations.",

Pachymic acid (PA), a bioactive triterpenoid, exhibits anti-inflammatory, antihyperglycemic, antihyperlipidemic, and sedative-hypnotic properties, though its role in circadian regulation remains unexplored. We assessed PA's impact on metabolic dysfunction (glucose/lipid profiles), systemic inflammation using biochemical assays, ELISA, Oil Red O staining. Circadian parameters were evaluated via 24-h serum melatonin and core body temperature. Hepatic circadian gene oscillations and mechanistic pathways were analyzed through time-series RNA sequencing, bioinformatics, qPCR, and Western blotting. PA intervention attenuated obesity-related phenotypes, including reduced body weight, improved glucose/lipid metabolism, and restored physiological rhythms of melatonin and body temperature. And hepatic gene oscillation patterns were realigned to circadian synchrony. Mechanistically, PA ameliorated liver inflammation by modulating the sphingolipid pathway, specifically via S1PR4/TRAF2 signaling. Our findings illustrate PA's role in mitigating metabolic and circadian disruptions in obesity, highlighting the sphingolipid pathway as a tissue-specific target for circadian modulation. This study provides novel insights into therapeutic strategies for obesity-associated circadian disorders.",
"42386554": "ID: 42386554\nTitle: Formation of Conjugated Polyenes, Malondialdehyde and Methylglyoxal in French Fries Produced with Four Different Types of Oils.\nAbstract: Lipid peroxidation products in French fries are a potential risk factor for non-communicable diseases. Malondialdehyde and methylglyoxal are among the most pathophysiologically-relevant lipid peroxidation products, but are generally not regarded as major products of the oxidation of linoleic acid- or monounsaturated fatty acid (MUFA)-rich oils, because mechanisms of their formation from such fatty acids are poorly understood. This study aimed to determine the formation of malondialdehyde and methylglyoxal, as well as conjugated dienes and conjugated trienes (precursors of secondary products including aldehydes) in French fries fried with four oils having different fatty acid composition. Conjugated dienes and trienes (CDs and CTs, respectively) were determined spectrophotometrically, malondialdehyde by the thiobarbituric acid test, and methylglyoxal by high performance liquid chromatography (HPLC). CT formation occurred to the same extent in sunflower and canola oils although the former lacked fatty acids with at least three double bonds, signifying desaturation of fatty acids during lipid peroxidation. More malondialdehyde was formed in sunflower oil containing more linoleic acid than canola oil with higher \u03b1-linolenic acid (18:3, n-3) content, indicating the importance of linoleic acid as a malondialdehyde precursor. Olive oil generated more malondialdehyde, methylglyoxal, CD and CT than palm olein, which is attributable to greater monounsaturated fatty acid content in the former. Mechanisms are proposed for the formation of CDs, CTs, malondialdehyde and methylglyoxal from MUFA and linoleic acid. Thus, MUFA- and linoleic acid-rich oils are relevant as sources of the two dialdehydes in fried foods. CDs and CTs can be considered as appropriate for monitoring lipid peroxidation even in MUFA- or linoleic acid-rich oils. Furthermore, formation of CDs through fatty acid desaturation helps to explain the formation of some 'unexpected' lipid oxidation products.",

To comprehensively evaluate the overall effects of low-GI diets on glycemic and lipid profiles across diverse populations and to identify potential differences in outcomes among subgroups. This systematic review and meta-analysis, conducted following PRISMA guidelines, searched PubMed, Embase, Cochrane Library, and Web of Science through April 2025. Weighted Mean Difference (WMD) with 95% Confidence Interval (CI) was calculated. Subgroup and sensitivity analyses explored heterogeneity and robustness. Twenty-five RCTs involving 1,973 participants (12-75 years) were included. Low-GI diets significantly reduced fasting blood glucose (FBG; -0.19 mmol/L, p = 0.04), glycated hemoglobin (HbA1c; -0.22%, p < 0.01), and low-density lipoprotein cholesterol (LDL-C; -0.15 mmol/L, p < 0.01) compared with control diets. Although not statistically significant, low-GI diets tended to increase High-Density Lipoprotein Cholesterol (HDL-C) and reduce Fasting Insulin (FI), Homeostasis Model Assessment of Insulin Resistance (HOMA-IR), Triglycerides (TG), and Total Cholesterol (TC). Subgroup analyses revealed stronger benefits in Type 2 Diabetes Mellitus (T2DM), individuals with baseline FBG \u2265 6.1 mmol/L, trials with intervention duration \u2265 12 weeks, and people in the Asia-Pacific region. Sensitivity analyses provided confirmation of the reliability of these outcomes. Low-GI diets improve glycemic control and modestly lower LDL-C, particularly in metabolically high-risk populations and with sustained intervention. These results highlight low-- GI diets as a practical nutritional strategy for metabolic health, while suggesting that baseline glucose status, intervention length, and population characteristics influence their effectiveness.",

However, the metabolic alterations in m.3243A>G carriers, including what differentiates those with and without diabetes, remain incompletely understood. To investigate metabolomic profiles in fasting serum and urine samples from m.3243A>G carriers compared to healthy controls. Metabolomic profiling of serum and urine samples using nuclear magnetic resonance-based metabolomics in m.3243A>G carriers (n\u2009=\u200928) was compared to healthy controls matched for age and sex. Additionally, profiles from m.3243A>G carriers with diabetes (n\u2009=\u200916) were compared with carriers without diabetes (n\u2009=\u200912) to identify potential metabolites associated with the presence of diabetes. Twenty-five metabolites in serum and 16 in urine were identified as metabolites separating m.3243A>G carriers from healthy controls. The m.3243A>G carriers presented with increased triglycerides across lipoprotein particles and altered very-low-density lipoprotein concentrations and composition. In addition, there were alterations in metabolites from a number of metabolic pathways, including glycolysis, the tricarboxylic acid cycle, glutathione, one-carbon, and nucleotide metabolism. A three metabolite-urine signature (uracil, hypoxanthine, and 1-methylnicotinamide) demonstrated discriminating potential between m.3243A>G carriers and controls in exploratory machine learning analyses (area under the curve values 0.94-0.99 and cross-validation prediction of 0.81-0.93). Among m.3243A>G carriers, branched-chain amino acids were higher in individuals with diabetes compared with carriers without diabetes. Dysregulated lipoprotein metabolism represents a significant metabolic fingerprint of m.3243A>G carriers. Furthermore, higher levels of branched-chain amino acids may be associated with the presence of diabetes.",

Adult Sprague-Dawley rats (41 males, 40 females) and cynomolgus macaques (10 per sex) were sampled after free access to food and after 8 hours of fasting. Fed rats demonstrated lower reticulocyte and neutrophil counts in males only. Higher alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase activities and higher glucose, triglyceride, cholesterol, and globulin concentrations were observed with lower urea nitrogen, albumin, and phosphorus concentrations in fed compared with fasted rats of both sexes. Fed macaques of both sexes demonstrated higher triglyceride concentrations and lower phosphorus and total bilirubin concentrations. All changes in fed compared with fasted rats and macaques were considered minor. Non-fasting did not impact coagulation parameters in rats and macaques or hematology parameters in macaques.

In the present study, we analyzed the FAs and transcriptomic profiles of marine dinoflagellates Amphidinium carterae (D-044) and Prorocentrum minimum (D-127) to evaluate their potential as FAs producers. Gas chromatography-FA methyl ester (GC-FAME) analysis showed that A. carterae is a superior omega-3 producer, yielding a total FA content of 67.6 mg/g DW. DHA accounted for 26.7% of the total FAME profile, which is significantly higher than that of P. minimum (18.1 mg/g DW; DHA 13.1%). Gene Ontology (GO) annotation revealed genes related to FAs and lipid metabolism in A. carterae (1,217 genes) and in P. minimum (2,317 genes), which provide a molecular basis for dinoflagellates with high lipid productivity. Notably, three lipid droplet-associated hydrolase (LDAH) genes with diverse evolutionary origins were identified from A. carterae.

Glycolipid metabolism 7 factors (GLM7) is a composite glycolipid metabolism index derived from routinely measured metabolic indicators; however, its relevance to pregnancy loss in young women remains unexamined. The present study analyzed publicly available data from the 2009-2018 National Health and Nutrition Examination Survey (NHANES) cycles. Participants were categorized as having no pregnancy loss, single pregnancy loss, or recurrent pregnancy loss (\u2265\u20092 losses). GLM7 was calculated as the logarithm of the product of age, body mass index, fasting blood glucose, fasting insulin, triglycerides, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol levels. The association between GLM7 and pregnancy loss categories was evaluated, potential dose-response patterns were explored, and effect modification by selected sociodemographic and behavioral factors was assessed. Of the 736 women included in the analysis, 300 (37%) reported a history of pregnancy loss. In binary analyses, higher GLM7 was initially associated with pregnancy loss (OR\u2009=\u20091.21, 95% CI: 1.03-1.44); however, the association was attenuated after adjustment for the number of pregnancies (OR\u2009=\u20091.19, 95% CI: 0.99-1.44). In multinomial analyses, higher GLM7 levels were not significantly associated with single pregnancy loss. In contrast, higher GLM7 remained independently associated with recurrent pregnancy loss after adjustment for all covariates (OR\u2009=\u20091.17, 95% CI: 1.02-1.42; P\u2009=\u20090.046). Women in the second to fourth quartiles had significantly higher odds of recurrent pregnancy loss than those in the lowest quartile. No significant nonlinearity was observed in the association between GLM7 and recurrent pregnancy loss (P for nonlinearity\u2009=\u20090.265). No statistically significant interaction was observed across the subgroups. In this nationally representative sample of U.S. women aged 18-35\u00a0years, higher GLM7 levels were more robustly associated with recurrent rather than isolated pregnancy loss. The findings suggested that cumulative glycolipid metabolic burden may be particularly relevant to repeated reproductive failures and serve as indicators to improved strategies for early reproductive risk identification and preventive healthcare for women.",

Cardiometabolic index (CMI), a novel lipid index, has been confirmed to be associated with obesity-associated metabolic disorders, such as diabetes and cardiovascular disorders. Despite these findings, the exact relationship between CMI and sleep disorders remains to be fully validated. Consequently, our objective was to investigate the association between CMI and sleep disorders using data from the National Health and Nutrition Examination Survey (NHANES). Based on data from NHANES spanning 2015 to 2020, this study employed weighted multivariate logistic regression and restricted cubic spline (RCS) regression analysis to investigate the relationship between CMI and sleep disorders. Additionally, receiver operating characteristic analysis and the area under the curve were also utilized to assess the predictive performance of CMI for sleep disorders. Subgroup analyses and interaction tests were conducted to examine the consistency of this association across different populations. A positive association between CMI and sleep disorders was found in a cohort comprising 5817 participants aged 20 and above, which was further verified to be nonlinear through RCS regression analysis. Within the context of a fully adjusted model, when CMI was considered as a continuous variable, each one-unit increase was linked to a 17% increase in the prevalence of sleep disorders (odds ratio [OR]\u2005=\u20051.17; 95% CI: 1.06-1.29; P\u2005=\u2005.004). Upon stratifying CMI into quartiles, it was observed that participants in the highest quartile exhibited an 81% greater risk of developing sleep disorders compared to those in the lowest quartile (OR\u2005=\u20051.81; 95% confidence interval [CI]: 1.29-2.54; P\u2005=\u2005.002). Subgroup analyses and interaction tests demonstrated that the association between CMI and sleep disorders remained consistent across different subgroups, and no significant modification of this relationship was observed by other covariates except for body mass index. An elevated CMI is correlated with a higher probability of sleep disorders among individuals in the United States. Given the difficulty in establishing a causal relationship between the 2, further extensive prospective studies are necessary to investigate the role of CMI in the development of sleep disorders.",

Dietary lipids and gut microbiota have emerged as major modulators of its activity and signaling tone. Intake of specific fatty acids, including the monounsaturated oleic acid, the omega-6 polyunsaturated linoleic acid, and omega-3 polyunsaturated fatty acids, influences the eCBome not only by serving as structural precursors of bioactive lipid mediators, but also by altering the relative abundance of these mediators through changes in substrate availability, enzymatic competition, and receptor-mediated feedback loops. Concurrently, gut microbiota shape host eCBome signaling by regulating lipid metabolism, inflammatory tone, and intestinal barrier integrity, while eCBome mediators reciprocally modulate microbial composition and function. Dysregulation of this complex diet-microbiota-eCBome interplay has been implicated in the pathogenesis of metabolic disorders, chronic inflammation, and neuropsychiatric conditions. In this review, we critically examine the molecular mechanisms underlying the interactions between dietary lipid composition, gut microbial ecology, and eCBome signaling. We discuss the implications for human health and highlight emerging diet-based therapeutic strategies targeting this axis.",

In this review, KD refers to adult dietary interventions intended to induce nutritional ketosis through marked carbohydrate restriction, while acknowledging that ketogenic diet therapy (KDT) is a broader umbrella term encompassing several protocol variants. We systematically searched PubMed, Embase, Web of Science, and the Cochrane Library from inception to March 2026, and we additionally searched gray literature sources (ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform, medRxiv, conference proceedings, and reference lists). Eligible studies included randomized controlled trials (RCTs), prospective cohorts, and observational studies of adult KD interventions (generally\u2009<\u200910% of energy from carbohydrate or <\u200950\u00a0g/day). Primary outcomes were lipid changes; secondary outcomes included glycemia, anthropometrics, and blood pressure; exploratory outcomes were mortality and atherosclerosis. Random-effects meta-analyses generated pooled estimates. The protocol was not prospectively registered. Twenty-four studies (20 RCTs, 2 prospective cohorts, 1 non-randomized clinical trial, and 1 pilot intervention; >47,000 participants) were included. Compared with control diets, KD increased low-density lipoprotein cholesterol (LDL-C) (mean difference [MD]\u2009+\u200912.2\u00a0mg/dL, 95% CI 7.5 to 16.9; I2\u2009=\u200967.7%) and total cholesterol, while high-density lipoprotein cholesterol (HDL-C) rose modestly. Triglycerides decreased overall (MD -16.1\u00a0mg/dL, 95% CI -20.3 to -11.8; I2\u2009=\u200917.1%). KD also improved fasting glucose, glycated hemoglobin, body weight, body mass index, and systolic blood pressure. Cohort evidence suggested lower all-cause mortality but no clear reduction in cardiovascular mortality. Imaging evidence for atherosclerosis was limited and mixed. KD was associated with improvements in adiposity, glycemic control, and blood pressure, but also with higher LDL-C and total cholesterol. Evidence for clinical cardiovascular endpoints remains limited, mixed, and mostly low certainty, supporting individualized risk-benefit assessment rather than universal adoption of KD.",

Migration out of Africa was enabled by the evolution of behaviors that increased human-vector contact, and as Ae. aegypti became more domesticated, arboviral competence may have also increased. Here we investigate variation in vector competence between present-day populations of Ae. aegypti from Florida (USA) and Tanzania (East Africa) and use a genomics approach to examine genetic differentiation potentially underlying traits important for arbovirus transmission. Using vector-competence experiments with dengue virus serotype 2, we demonstrate greater susceptibility to infection in American mosquitoes, along with higher viral loads and a shorter time to virus dissemination. We then sought to identify highly divergent genes potentially underlying these differences and discovered more than 1.6 million single nucleotide polymorphisms via exome sequencing. Of these, 1058 were highly differentiated between populations (FST\u2009>\u20090.9) with more than half mapping to 17 outlier genes influencing chromatin remodeling, lipid metabolism, glycosylation, circadian rhythms, olfaction, and saliva bioactivity. Eight of these outlier genes formed a highly divergent genomic island on chromosome 2. Allele-frequency patterns of outlier genes across Ae. aegypti's range highlight genetic differentiation within sub-Saharan Africa, as well as evolutionary changes accompanying the shift towards domestication in the Americas and Asia. This work offers insights into phenotypic variation and evolutionary divergence within Ae. aegypti, including naturally occurring genetic variants that may influence transmission-related characters.",

Databases including PubMed, Web of Science, the Cochrane Library and Embase were systematically searched from inception to March 19, 2026. The Cochrane Risk of Bias Assessment Tool (RoB 2.0) was used for study quality evaluation. Meta-analysis was conducted with RevMan 5.4 and Stata 17.0. The study was prospectively registered in PROSPERO (CRD420251125178) and reported following PRISMA guidelines. Eleven randomized controlled trials involving 780 participants were included. Probiotic and synbiotic supplementation significantly reduced fasting insulin (MD\u2009=\u2009-\u20091.41, 95% CI: -2.76 to -\u20090.05), total testosterone (MD\u2009=\u2009-\u20090.19, 95% CI: -0.25 to -\u20090.12), triglycerides (MD\u2009=\u2009-\u200912.28, 95% CI: -24.21 to -\u20090.35), low-density lipoprotein cholesterol (MD\u2009=\u2009-\u20096.19, 95% CI: -10.08 to -\u20092.30), BMI (MD\u2009=\u2009-\u20090.49, 95% CI: -0.88 to -\u20090.10), and body weight (MD\u2009=\u2009-\u20091.07, 95% CI: -2.08 to -\u20090.05), while increasing high-density lipoprotein cholesterol (MD\u2009=\u20091.73, 95% CI: 0.40 to 3.06) and total antioxidant capacity (MD\u2009=\u2009124.02, 95% CI: 40.49 to 207.54). No significant effects were observed for fasting glucose, HOMA-IR, QUICKI, FSH, LH, SHBG, DHEAS, total cholesterol, C-reactive protein, waist circumference, or hip circumference. The single prebiotic trial contributed only to the meta-analyses of BMI, body weight, and waist circumference. According to the GRADE framework, the certainty of evidence was high for Testosterone, TG, LDL\u2011C, HDL\u2011C, BMI, and body weight, moderate for fasting insulin, and low for total antioxidant capacity. Probiotic or synbiotic supplementation significantly improves multiple clinical parameters in women with PCOS, including reductions in fasting insulin, total testosterone, triglycerides, LDL cholesterol, BMI, and body weight, while increasing HDL cholesterol and total antioxidant capacity. However, the effects on fasting blood glucose, HOMA-IR, and certain sex hormones remain unclear and require further validation. The single available prebiotic trial showed benefits only for BMI and body weight, but its evidence is limited. Not applicable.",

"42422382": "ID: 42422382\nTitle: The impact of maximal fat oxidation intensity exercise on glucose and lipid metabolism in individuals with overweight or obesity: A systematic review and meta-analysis.\nAbstract: This study provides the first quantitative synthesis evaluating the chronic effects of FATmax training on glucose and lipid metabolism in individuals with overweight or obesity, while systematically exploring the moderating roles of participant characteristics and intervention protocols. A comprehensive search of seven databases (e.g., PubMed, Web of Science) was conducted up to August 2025, identifying 24 controlled trials involving 638 participants. Random-effects meta-analyses showed that FATmax training produced significant improvements in multiple glycolipid metabolic markers. Specifically, large standardized reductions were observed in fasting plasma glucose (Hedges' g = -1.05), insulin resistance (Hedges' g = -0.82), and fasting insulin (Hedges' g = -0.75), alongside moderate improvements in triglycerides (Hedges' g = -0.55), total cholesterol (Hedges' g = -0.23), and high-density lipoprotein cholesterol (HDL-C; Hedges' g = 0.51). Notably, the large standardized effects on glycemic markers suggest potentially clinically meaningful improvements in glycemic control. Subgroup analyses indicated that HDL-C adaptations were significantly enhanced in male participants, weight-bearing modalities, and protocols incorporating warm-up sessions or concurrent dietary restriction (p < 0.05). Furthermore, meta-regression identified baseline HDL-C (\u03b2= -2.955), exercise intensity (\u03b2 = 0.053), and session duration (\u03b2 = 0.058) as significant predictors of HDL-C improvement. Crucially, we derive the first clinically actionable, personalized thresholds from interaction analyses: for individuals with low baseline HDL-C (\u2264 1.36 mmol/L), efficacy is maximized when session duration exceeds 60 minutes (Hedges' g = 1.19) or intensity surpasses 42.2% V \u02d9 O2max (Hedges' g = 1.10); whereas for those with higher baseline levels, extending duration (\u2265 60 min) is the primary requisite for significant benefits (Hedges' g = 0.61). In conclusion, FATmax training produces significant and potentially clinically meaningful improvements in glucose and lipid metabolism in individuals with overweight or obesity. These effects are modulated by individual characteristics and intervention parameters. Future research should prioritize standardized FATmax determination protocols and diverse populations to validate these personalized prescription parameters.",

In a 24-month non-blinded randomized controlled trial (Clinicaltrial.gov: NCT00427193) of non-obese (BMI 22-27.9\u2009kg/m2) men and premenopausal women aged 21 to 50 years, we assessed prespecified outcomes. Participants were randomized to an ad libitum or CR diet. We found that CR was associated with increased high-molecular-weight (HMW) adiponectin and reduced circulating ceramide species implicated in insulin resistance, including C16:0, C18:0, and C24:0. Mediation analysis indicated that reductions in ceramides were statistically compatible with partial mediation of the CR-associated improvements in insulin secretion, insulin sensitivity, and IGF-1 signaling markers. These effects were most pronounced at 12 months and attenuated by 24 months, suggesting partial metabolic adaptation over time. Overall, our findings are consistent with a model in which CR remodels bioactive lipid profiles and may enhance glucose metabolism in part through an adiponectin-ceramide-linked mechanism, highlighting a potential therapeutic axis for enhancing metabolic health.",

Cyclocarya paliurus polysaccharides (CCPP) have been shown to improve lipid metabolism and modulate the gut microbiota; however, mechanistic evidence remains limited and may vary depending on preparation methods. This study investigated whether a crude polysaccharide-enriched Cyclocarya paliurus preparation alleviates high-fat diet-induced metabolic dysfunction and is associated with gut microbiota remodeling. Male C57BL/6\u2009J mice were randomized into three groups: normal diet (ND), high-fat diet (HFD), and HFD supplemented with CCPP for 12\u2009weeks. Serum metabolic parameters were measured; intestinal inflammatory cytokine transcripts were assessed by qRT-PCR; and cecal microbiota composition was analyzed by 16S rRNA gene sequencing. Additionally, fecal microbiota transplantation (FMT) was performed by transferring microbiota from CCPP-treated donors to antibiotic-pretreated HFD-induced recipients for 8\u2009weeks. CCPP attenuated HFD-induced body weight gain and reduced subcutaneous and visceral adipose tissue mass. CCPP significantly improved serum total cholesterol and low-density lipoprotein cholesterol (LDL-C) and reduced fasting glucose. Cecal 16S rRNA gene profiling showed that CCPP reshaped the gut dysbiosis associated with a HFD and enriched microbial taxa that are commonly linked to carbohydrate fermentation. These taxa specifically include Lachnospiraceae-related microbial taxa and Ileibacterium. Importantly, FMT from CCPP-treated donors recapitulated these metabolic improvements, confirming that the benefits of CCPP were microbiota-dependent. CCPP mitigates obesity and metabolic dysfunction by remodeling the gut microbiota, particularly by enriching short-chain fatty acid-producing taxa. These findings highlight CCPP as a potential microbiota-targeted therapeutic agent for metabolic disorders.",

Chaihu Guizhi Ganjiang Tang (CHGZGJT), a classical formula derived from the ancient canonical text Shanghan Lun (Treatise on Cold Damage Diseases), has been reported to improve glucose and lipid metabolism as well as islet function in patients with T2DM. However, a quantitative evidence-based evaluation is currently lacking. This study aimed to systematically evaluate the overall efficacy and safety of CHGZGJT. This study was registered on the PROSPERO platform. Eight Chinese and English databases and two clinical trial registries were systematically searched, and 12 clinical controlled trials involving a total of 883 patients were ultimately included. Meta-analysis were performed using R software to assess efficacy and safety. The meta-analysis suggested that CHGZGJT combined with conventional treatment significantly reduced glycated hemoglobin (HbA1c, MD = -0.69%), fasting plasma glucose (FPG, MD = -0.86\u00a0mmol/L), and 2-h postprandial glucose (2hPG, MD = -0.74\u00a0mmol/L) in patients with T2DM. At the mechanistic level, this regimen significantly decreased fasting insulin (FINS, MD = -2.08\u00a0\u00b5IU/mL) and the homeostasis model assessment of insulin resistance (HOMA-IR, MD = -0.79), improved islet \u03b2-cell function (HOMA-\u03b2, MD = 5.13), and lowered total cholesterol, triglyceride, and low-density lipoprotein cholesterol levels, with a lower risk of adverse events (RR = 0.44). CHGZGJT may improve glycemic control, insulin resistance, \u03b2-cell function, and the lipid profile in patients with T2DM, with a favorable safety profile for short-term administration. However, the quality of evidence from the included studies was low to moderate, and high-quality clinical trials are still warranted to further verify its long-term efficacy and safety.",

Beyond mechanical loading, accumulating evidence indicates that OA is increasingly recognized as a whole\u2011joint disorder shaped by the interplay between local tissue damage and systemic endocrine\u2011metabolic imbalance. Endocrine factors, including sex hormones, thyroid hormone, melatonin, parathyroid hormone and vitamin D, together with metabolic disturbances, such as obesity, insulin resistance, dysregulated glucose and lipid metabolism and gut microbiota imbalances, can cooperatively remodel the joint microenvironment. Mechanistically, these alterations converge on immuno\u2011inflammatory amplification, mitochondrial dysfunction, oxidative stress, cellular senescence, metabolic reprogramming and regulated cell death, thereby promoting extracellular matrix degradation, persistent synovitis and uncoupled bone\u2011cartilage remodeling. The present review systematically summarizes the molecular basis of endocrine\u2011metabolic crosstalk in OA and discusses emerging therapeutic opportunities targeting hormonal signaling, metabolic pathways, circadian regulation, nutritional support and lifestyle interventions. Nevertheless, the reciprocal interactions among endocrine signals, systemic metabolic abnormalities and local joint pathology remain incompletely understood, and their translation into mechanism\u2011based clinical stratification remains at an early stage. Thus, targeting endocrine\u2011metabolic crosstalk may support mechanism\u2011based phenotyping and subtype\u2011informed precision therapy for OA, provided that candidate biomarkers and interventions are validated in prospective clinical studies.",
"42429130": "ID: 42429130\nTitle: The role of central regulators in lipid hydroperoxide-mediated muscle atrophy. Exploring mechanisms beyond ferroptosis.\nAbstract: The oxidation of lipids in biological systems generates lipid hydroperoxides, which are implicated in cellular dysfunction, such as arteriosclerosis and cognitive decline. Although multiple lipid species, including phospholipids, ceramides, triglycerides, and free fatty acids, are susceptible to oxidation, the specific lipid species that drive disease development remain poorly defined. Lipid oxidation is primarily initiated and propagated by reactive oxygen species (ROS). ROS are highly reactive molecules that participate in diverse and complex intracellular signaling pathways. Ferroptosis is a recently identified form of regulated, non-apoptotic cell death characterized by iron-dependent accumulation of lipid peroxides, especially the peroxidation of polyunsaturated fatty acids in cellular membranes, ultimately leading to loss of membrane integrity. Oxidized phospholipids are considered key execution factors in ferroptosis, suggesting an important role for lipid peroxidation in maintaining physiological homeostasis across multiple organs. Our group recently demonstrated that oxidized phospholipids could serve as a source of ROS, thereby promoting muscle atrophy. In the present review, we summarize emerging evidence that membrane lipids, particularly oxidation of phospholipids and polyunsaturated fatty acids, contribute to the generation and propagation of cellular ROS, ultimately facilitating muscle atrophy.",

Ferroptosis, an iron-dependent regulated cell death pathway driven by the accumulation of lipid peroxidation in cell membranes, has been implicated in age-related disorders. This study investigated the relationship between cellular senescence and ferroptosis. Using human fetal lung WI-38 fibroblasts induced to senesce via replicative exhaustion, we report a novel role for acid ceramidase (ACase), which breaks down ceramides into sphingosine and free fatty acids, in regulating the sensitivity of senescent cells to RSL3-induced lipid peroxidation and ferroptosis through the modulation of polyunsaturated fatty acid composition of membrane phospholipids. Furthermore, we demonstrate a cell non-autonomous paracrine sensitization of non-senescent cells to ferroptosis by senescent cells. Together, these findings unveil ACase as a novel regulator of the ferroptosis pathway and open promising therapeutic avenues for targeting senescence-linked disorders and advancing healthy aging strategies.",
"42432438": "ID: 42432438\nTitle: Phenylacetic Acid, a Gut Microbially Produced Metabolite, Reduces Atherosclerosis Burden and Impacts Host Lipid Homeostasis.\nAbstract: Gut microbial metabolism of dietary phenylalanine produces phenylacetic acid (PAA), followed by the host conversion to phenylacetylglutamine in humans and phenylacetylglycine in mice. Phenylacetylglutamine was linked to cardiovascular disease risk in multiple clinical studies, yet whether the microbial pathways leading to PAA/phenylacetylglutamine/phenylacetylglycine formation influence atherosclerosis progression within the host remains elusive. Atheroprone Apoe-/- mice on a Western diet were provided with a gut microbial metabolite PAA to investigate its effects on host cardiometabolic health. Circulating levels of phenylacetylglutamine and phenylacetylglycine were increased by the treatment without affecting circulating cholesterol or inflammatory cytokines. In male mice, PAA elevated triglycerides and fasting glucose. PAA decreased the total atherosclerotic plaque burden within the descending and abdominal aortas of both sexes and within brachiocephalic arteries in male mice without affecting plaque stability indices. PAA altered gut microbial composition but did not markedly shift production of established atherosclerosis-related microbial metabolites, aside from a modest rise in indoxyl sulfate in female mice. Furthermore, PAA treatment decreased circulating levels of acyl- and free carnitines through reduced availability of their biosynthetic precursors and upregulated expression of genes involved in peroxisomal lipid metabolism. These results offer new insights into the impact of gut-microbial metabolism of phenylalanine on host metabolism and atherosclerosis progression. Our findings suggest that clinical associations between phenylacetylglutamine and cardiovascular disease risk are unlikely to be driven by increased atherosclerosis.",
"42432891": "ID: 42432891\nTitle: Risk factors for distal symmetric polyneuropathy in patients with type 2 diabetes mellitus: A retrospective study.\nAbstract: The pathophysiology of distal symmetric polyneuropathy (DSPN) is multifactorial, involving chronic hyperglycemia, oxidative stress, accumulation of advanced glycation end products, impaired microvascular perfusion, metabolic toxicity, and nutritional deficiencies. Although previous studies have identified various risk factors, substantial heterogeneity exists across regions and populations, and most investigations have not comprehensively integrated metabolic markers, microvascular damage, and electrophysiological data. Therefore, a multidimensional assessment of DSPN risk factors is essential to improve early screening and risk-prediction strategies. A total of 120 patients with type 2 diabetes mellitus (T2DM) were enrolled, including 60 with DSPN and 60 without. Compared with the non-DSPN group, patients with DSPN were older, had longer diabetes duration, and demonstrated a higher prevalence of smoking, diabetic retinopathy (DR), and diabetic kidney disease. DSPN patients exhibited poorer glycemic control (higher fasting blood glucose, 2-hour postprandial blood glucose, and hemoglobin A1c [HbA1c]), more pronounced dyslipidemia (elevated triglycerides, reduced high-density lipoprotein cholesterol), and abnormalities in inflammatory and nutritional markers (elevated C-reactive protein and homocysteine [HCY], reduced vitamin B12). Renal function parameters (serum creatinine, estimated glomerular filtration rate, urine albumin-creatinine ratio) indicated more severe microvascular impairment in the DSPN group. Electrophysiological testing showed reduced sensory and motor nerve conduction velocities, decreased amplitudes, and prolonged latencies. Multivariable logistic regression identified diabetes duration, DR, elevated HbA1c, elevated HCY, and reduced sural nerve amplitude as independent risk factors for DSPN. Longer diabetes duration, DR, elevated HbA1c, elevated HCY levels, and reduced sural nerve amplitude were independently associated with DSPN in patients with T2DM. These findings may contribute to improved risk stratification and support further investigation of multidimensional approaches for early DSPN identification. This single-center retrospective cohort study included patients with T2DM treated at our hospital between June 2023 and June 2025. DSPN was diagnosed based on American Diabetes Association, European Federation of Neurological Societies, and diabetic neuropathy working group criteria using a combination of clinical symptoms, neurological signs, and nerve conduction studies. Demographic characteristics, lifestyle factors, diabetes-related complications, glucose and lipid metabolism indicators, renal function, inflammatory and nutritional markers, and electrophysiological parameters were collected. Group differences were assessed using the t-test, Mann-Whitney U test, or \u03c72 test. Variables with P\u2005<\u2005.10 in univariate analyses were entered into multivariable logistic regression to identify independent risk factors for DSPN. Sensitivity analyses and collinearity diagnostics were performed to assess the robustness of the findings.",

Glucocorticoid (GC) replacement therapy is crucial for ensuring patient survival and guaranteeing an adequate quality of life. GC replacement therapy requires a balance between undertreatment, with the consequent risk of adrenal crisis, and overtreatment, which can have long-term effects on the metabolic and cardiovascular systems. We conducted a retrospective, longitudinal, observational study on 140 patients affected by pituitary disease with at least 3\u00a0years of follow-up. Patients were consecutively included in the study with a ratio 1:1, considering patients affected by SAI and who were therefore on GCs replacement therapy, and patients with pituitary disease without SAI (controls). Worsening of glucose metabolism occurred in 29 patients with SAI (64.4%) and in 16 controls (35.6%, p\u2009=\u20090.019). Worsening of lipid metabolism occurred in 52 patients with SAI (56.5%) and in 40 controls (43.5% p\u2009=\u20090.033). GC replacement therapy (p\u2009=\u20090.014, OR: 2.3, 95%IC: 1.1-4.9), higher fasting glycaemia at baseline (p\u2009=\u20090.04, OR: 7.6, 95%IC: 2.3-25.4), IGT/T2DM at baseline (p\u2009=\u20090.016, OR: 8.6, 95%IC: 0.8-57) were the main risk factors for the worsening of glucose metabolism at 3-year follow-up. TSH deficit remained the only risk factor for the worsening of lipid profile (p\u2009<\u20090.001, OR: 2.9, 95%IC: 1.3-6.5). Our study proved that GCs replacement therapy may be associated with a worsening of glucose metabolism, particularly in patients already affected by IGT/T2DM.

Herein, wheat gluten peptide nanoparticles (WGPNs) with coupled emulsifying and antioxidant functions were produced by sequential pepsin-trypsin hydrolysis. LC-MS/MS showed a peptide pool (1-4 kDa) enriched in Gln/Pro, featuring hydrophobic motifs and C-terminal Lys/Arg residues that confer surfactant-like behavior. WGPNs formed spontaneously in aqueous media, mainly driven by hydrophobic association and hydrogen bonding, with concentration-dependent \u03b2-sheet formation and a critical aggregation concentration of \u223c0.17 mg/mL. Above this threshold, WGPNs exhibited enhanced radical-scavenging activity and colloidal stability across a wide ionic-strength range. Interfacial measurements demonstrated rapid adsorption of WGPNs at the oil-water interface, reduced interfacial tension, and formation of a stable interfacial layer. Consequently, WGPNs effectively stabilized fish oil emulsions and markedly retarded lipid oxidation. This work establishes WGPNs as a clean-label, dual-function platform for protecting oxidation-sensitive lipids in food systems.",

Characterizing how circadian misalignment alters circulating metabolites provides a promising avenue to help identify these mechanisms. Although data from metabolomics studies have identified circulating metabolites with daily rhythms, it is not comprehensively known which rhythms shift during circadian misalignment and whether such shifts relate to metabolic impairment. We conducted 24-hour (h) metabolomic profiling every 4 h in 14 healthy adults (8 women) aged 26.4\u2009\u00b1\u20091.2\u2009years (mean\u2009\u00b1\u2009SD), undergoing a 6-day simulated night-shiftwork protocol. 24-h modeling analyses identified metabolite rhythms influenced by circadian versus behavioral cycles (sleep, food intake) and quantified internal circadian misalignment using acrophase shifts. Metabolic outcomes included glucose homeostasis (test meals) and energy expenditure (EE; whole-room calorimetry). Night-shiftwork produced widespread alterations in metabolite rhythms, with significant internal misalignment in multiple metabolites across pathways including pyrimidine metabolism, bile acid-microbiome signaling, and lipid metabolism. During misalignment, glucose and insulin area under the curve increased (p\u2009<\u20090.05) and EE decreased (p\u2009<\u20090.05). Internal misalignment of uridine and glycoursodeoxycholic acid was associated (p\u2009<\u20090.05) with impaired glucose tolerance, while their circulating concentrations were associated with decreased EE. Misalignment of uridine and glycoursodeoxycholic acid suggests dysregulated pyrimidine and bile acid-microbiome pathways as potential mechanisms linking circadian misalignment to cardiometabolic disease risk.",

Nutritional strategies such as flaxseed supplementation may improve meat quality and lipid stability. This study evaluated the effects of flaxseed feeding duration and sheep ratios on the physicochemical composition, oxidative stability, color, texture, and consumer preference of mixed fresh sausages produced from the meat of aged sheep (>5\u00a0years) during 21\u00a0days of refrigerated storage at 4\u00b0C. Sausages were formulated with different sheep ratios (100:0, 90:10, 80:20, and 70:30) using meat from culled sheep supplemented with 15% flaxseed for 30, 45, or 60\u00a0days before slaughter. Flaxseed feeding period and formulation did not affect moisture, protein, ash content, or water activity (p\u00a0>\u00a00.05). However, increasing the flaxseed supplementation period from 30 to 60\u00a0days significantly improved the lipid composition of the sausages by reducing lipid content, increasing polyunsaturated fatty acids (PUFAs) and \u03c9-3 fatty acids, and decreasing the \u03c9-6/\u03c9-3 ratio. During refrigerated storage, pH and lipid oxidation increased, whereas water activity decreased (p\u00a0<\u00a00.05). Despite the higher PUFA content associated with longer supplementation periods, oxidative stability was maintained, with TBARS values remaining below levels commonly associated with sensory deterioration throughout the 21-day storage period. Increasing the proportion of sheep meat reduced lipid content, and all formulations met low-fat product criteria. Preference ranking results showed significant differences among formulations, while the relative preference order remained stable throughout refrigerated storage and across flaxseed supplementation periods. Color parameters were not affected by flaxseed supplementation but were influenced by formulation. Texture parameters were mainly affected by storage time, with increased hardness and chewiness observed during refrigerated storage. In conclusion, extending flaxseed supplementation from 30 to 60\u00a0days improved the nutritional lipid profile of sausages without compromising oxidative stability, color, texture, or consumer preference during 21\u00a0days of refrigerated storage. The preference ranking results further indicated that consumer preference patterns were maintained throughout storage, supporting the feasibility of incorporating culled sheep meat into low-fat fresh sausage formulations while adding value to this underutilized raw material. PRACTICAL APPLICATIONS: Meat from old or culled sheep can be effectively used in the production of mixed fresh sausages with good physicochemical stability and sensory acceptance during refrigerated storage. Sausage formulations containing 70%-80% sheep meat combined with pork allow the development of low-fat products without compromising texture, color, or oxidative stability. Flaxseed supplementation is used as a nutritional strategy to increase omega-3 fatty acids and improve the \u03c96/\u03c93 ratio in meat, contributing to improved nutritional quality. Flaxseed supplementation in the sheep diet does not negatively affect product quality and can be implemented without technological limitations. This feeding strategy may also enhance the fatty acid profile without requiring changes in meat processing conditions. This approach provides a practical alternative for valorizing low-market-value sheep meat, reducing waste, and supporting the development of cost-effective and nutritionally acceptable processed meat products for the food industry.",
"42439678": "ID: 42439678\nTitle: Follistatin Mitigates Atherosclerosis Through Activation of Arginine Metabolism and Adipose Browning.\nAbstract: Follistatin (FST) binds to and neutralizes members of the transforming growth factor-beta (TGF-\u03b2) superfamily, thereby regulating diverse physiological processes, including regulation of skeletal muscle, adipose, and bone homeostasis. FST also promotes adipose browning and enhances energy metabolism, leading to improved plasma lipid profiles and metabolic health in mice. Given the emerging association between brown adipose tissue (BAT) activation and reduced atherosclerosis, we investigated the anti-atherogenic potential of FST. Transcriptomic and metabolomic analyses of the Hybrid Mouse Diversity Panel (HMDP) revealed that Fst expression was negatively correlated with aortic lesion area and positively correlated with the expression of multiple adipose browning-associated genes. Adeno-associated viral delivery of Fst (AAV1-FST344) in Ldlr-/- mice significantly reduced aortic lesion area, improved plasma lipid profiles, and decreased expression of adhesion (VCAM1) and inflammatory (iNOS, TNF-\u03b1) markers in white adipose tissue (WAT), liver, and heart. Fst gene delivery also markedly increased uncoupling protein 1 (UCP1) expression in WAT, consistent with WAT browning. Integrated correlation analyses of Fst expression with tissue metabolites, together with plasma metabolite-lesion associations identified in the HMDP, implicated the arginase 1 (Arg1)-mediated metabolic pathway as a key regulator of atherogenesis. Consistent with these findings, Arg1 expression was significantly elevated in WAT, liver, and heart of AAV1-FST344-treated mice and in wild-type versus Fst-knockout mouse embryonic fibroblasts (MEFs). Immunostaining localized Arg1 predominantly to CD68+ macrophages in heart and liver. Given recent evidence identifying Arg1 as a novel mediator of efferocytosis, these findings suggest that Arg1 may promote macrophage metabolic reprogramming and resolution of inflammation by enhancing the clearance of apoptotic cells. Furthermore, Fst gene delivery increased the expression of fibroblast growth factor 21 (Fgf21) and adiponectin (AdipoQ) in WAT. Collectively, these findings identify Fst as a novel anti-atherogenic regulator that protects against vascular disease by promoting adipose browning, improving lipid metabolism, and activating Arg1-mediated metabolic pathways.",

Although CSF1R inhibitor-based studies have uncovered important roles for microglia in processes, such as anesthesia, addiction, and obesity, whether the resulting phenotypes reflect microglial depletion alone remains increasingly debated. Our previous work has shown that PLX5622 activates hepatic constitutive androstane receptor (CAR)-dependent xenobiotic metabolism, altering the metabolism of anesthetics and addictive drugs, and amplifying apparent microglial phenotypes. Whether other CSF1R inhibitors, particularly the FDA-approved PLX3397, exert systemic metabolic effects that may influence the interpretation of brain phenotypes remains unknown. Here, we demonstrate that PLX3397 exerts hepatic metabolic effects that are mechanistically distinct from those induced by PLX5622. Although PLX3397 only weakly affects xenobiotic metabolism, it markedly enhances endogenous hepatic lipid metabolism, inducing a fasting-like state characterized by increased lipid utilization and ketogenesis despite the absence of nutrient deprivation. By uncovering previously unrecognized peripheral effects of PLX3397, our findings identify brain-periphery interactions as a potential source of confounding in studies of microglial function. These results suggest that systemic metabolic effects should be carefully considered when interpreting neural or behavioral phenotypes in pharmacological microglia depletion paradigms.",

Although physical activity is recognised as an effective non-pharmacological intervention, most existing evidence synthesis has primarily focused on the role of physical activity in preventing obesity, with limited attention given to its effects on managing children with obesity. To synthesise evidence on the benefits and harms of physical activity for the management of obesity in children up to 9 years of age. We searched CENTRAL, MEDLINE, Embase, and two trial registries from 2012 to 2 June 2023, with an update on 4 December 2025. We also used Google Scholar to identify additional studies. We did not impose language or publication status restrictions. We included randomised controlled trials (RCTs) that investigated the effects of physical activity interventions of any frequency, mode (e.g. aerobic, resistance), or intensity, with a minimum intervention duration of 12 weeks, in children up to 9 years of age with obesity (as defined by the trialists) at baseline. Eligible comparators were standard care, waiting-list, no physical activity, or any other active interventions, such as comparisons of different physical activity parameters (e.g. duration, frequency, intensity). Critical outcomes: body mass index (BMI), BMI z-score, body weight, health-related quality of life, adiposity and fat distribution, glycaemia, and adverse events (minor and serious). Important outcomes: physical well-being, mental well-being, physical activity levels, blood pressure, hyperinsulinemia, resistance to insulin, alterations in lipid metabolism, presence of obesity-related comorbidities or any non-communicable diseases, obesity-associated disability, lipid hormones, alterations in hunger or satiety, disability, mortality, prevalence of obesity in adulthood, and access to health services. Pairs of review authors independently assessed the risk of bias in included studies using the original version of the Cochrane tool (RoB 1). We synthesised results using meta-analysis when appropriate. Given the clinical and statistical heterogeneity, we predominantly used a random-effects model alongside sensitivity analyses. When meta-analysis was not feasible, we employed synthesis without meta-analysis (SWiM) methods. We assessed the certainty of the evidence using the GRADE approach. We included four studies (five references, 517 children; female 46%; mean age ranged from 8.9 to 9.9) conducted in three countries (the USA, Brazil, and Iran). Three studies (75%) delivered the physical activity interventions in school settings. Three studies (75%) compared physical activity interventions with non-exercise controls, while one compared physical activity with a behaviour-changing intervention. The duration of physical activity interventions ranged from 12 to 32 weeks. We assessed three studies as having an overall high risk of bias. Physical activity interventions compared to control The evidence is very uncertain about the effect of physical activity interventions on BMI (mean difference (MD) -1.52 kg/m\u00b2, 95% confidence interval (CI) -2.74 to -0.29; I\u00b2 = 0%; 2 studies, 118 children; very low-certainty evidence), BMI z-scores (MD -0.10 z-score units, 95% CI -0.22 to 0.02; I\u00b2 = 29%; 1 study, 222 children; very low-certainty evidence), body weight (MD -0.86 kg, 95% CI -3.17 to 1.46; I\u00b2 = 0%; 2 studies, 118 children; very low-certainty evidence), health-related quality of life (MD -0.60 points, 95% CI -4.22 to 3.02; 1 study, 175 children; very low-certainty evidence), adiposity and fat distribution, assessed as body fat percentage (MD -1.23%, 95% CI -2.50 to 0.03; I\u00b2 = 0%; 3 studies, 456 children; very low-certainty evidence), minor adverse events (risk ratio (RR) 3.58, 95% CI 1.95 to 6.55; 1 study, 222 children; very low-certainty evidence), and serious adverse events (RR 1.08, 95% CI 0.10 to 11.76; 1 study, 222 children; very low-certainty evidence). No studies assessed glycaemia. Combined training (aquatic exercises) versus combined training (video game exercises) The evidence is very uncertain about the effect of combined training in an aquatic setting compared to video-game-based combined training on BMI (MD -0.90 kg/m\u00b2, 95% CI -3.21 to 1.41; 1 study, 39 children; very low-certainty evidence), BMI at 4-week follow-up (MD 0.03 kg/m\u00b2, 95% CI -2.54 to 2.60; 1 study, 39 children; very low-certainty evidence), body weight (MD -1.30 kg, 95% CI -5.66 to 3.06; 1 study, 39 children; very low-certainty evidence), and body weight at 4-week follow-up (MD -0.70 kg, 95% CI -5.70 to 4.30; 1 study, 39 children; very low-certainty evidence). This study did not assess the other critical outcomes. Low-dose versus high-dose combined training The evidence is very uncertain about the effect of low-dose versus high-dose combined training on BMI z-scores (MD 0.12 z-score units, 95% CI 0.10 to 0.14; 1 study, 144 children; very low-certainty evidence), adiposity and fat distribution, assessed as body fat percentage (MD 1.07%, 95% CI -0.74 to 2.88; 1 study, 144 children; very low-certainty evidence), glycaemia, assessed as fasting glucose level (MD -0.50 mg/dL, 95% CI -2.77 to 1.77; 1 study, 144 children; very low-certainty evidence), minor adverse events (RR 0.91, 95% CI 0.64 to 1.30; 1 study, 144 children; very low-certainty evidence), and serious adverse events (RR 3.08, 95% CI 0.13 to 74.45; 1 study, 144 children; very low-certainty evidence). This study did not assess the other critical outcomes. The evidence from four randomised studies on the effects of physical activity interventions in children aged 0 to 9 with obesity is of very low certainty. Serious methodological limitations, clinical heterogeneity, small-study effects, and imprecise results constrained this evidence base. Important knowledge gaps remain because none of the included RCTs enroled children with disabilities. The RCTs provided little information on contextual factors. Future high-quality and better-reported RCTs will likely change our findings.

The case-control study was conducted from April 2 to December 13, 2024, at the Department of Biochemistry and Molecular Biology, National University of Medical Sciences, Rawalpindi, Pakistan, in collaboration with the Chemical Pathology Laboratory, Army Medical College, Rawalpindi, and comprised dyslipidaemia cases and healthy controls. Genomic deoxyribonucleic acid extraction was done from blood samples using an organic method, and tetra-primer amplification refractory mutation system-polymerase chain reaction, followed by agarose gel electrophoresis. Data regarding lipid profile and fasting blood glucose was noted for all the participants. Data was analysed using SPSS 26. Of the 300 subjects, 150(50%) were in each of the two groups. There were 86(57%) males and 64(43%) females among the cases with mean age was 49.1\u00b111.6 years, and 76(52%) females and 72(48%) males with 43.3\u00b115.6 years among the controls. The rs373001 polymorphism of micro-ribonucleic acid-130b gene showed a C>T transition. The C allele (reference allele) frequency was n=123 (41%) in cases and n=144 (48%) in controls, while T allele (risk allele) frequency was n=177 (59%) in cases and n=156 (52%) in controls. The cases had 120(80%) CT, 1(0.7%) CC and 29(19.3%) TT genotypes, while the controls had 142(94.7%) CT, 1(0.7%) CC and 7(4.7%) TT genotypes. The TT genotype was a risk (adjusted odds ratio: 4.8, p<0.001) in recessive genetic model, while CT was protective (adjusted odds ratio: 0.2, p<0.001) in over-dominant model. A correlation was noted between genotypes and triglycerides levels (p=0.039) without confounders age and gender, but when adjusted with these confounders, no correlation was found (p>0.05). There was a positive association of the TT genotype of rs373001 polymorphism in micro-ribonucleic acid-130b gene with the risk of dyslipidaemia development in recessive genetic model and log-additive pattern of inheritance.",
"42445422": "ID: 42445422\nTitle: A nomogram based on systemic inflammatory markers: development and validation for predicting postoperative overall survival in gastric cancer.\nAbstract: Gastric cancer (GC) remains a leading cause of cancer-related mortality worldwide. Emerging evidence links dysregulated lipid metabolism and chronic systemic inflammation to GC progression, and a bidirectional regulatory loop between lipid metabolism reprogramming and tumor inflammation; however, most prognostic studies have evaluated these markers in isolation. We hypothesized that integrating lipid derivatives and systemic inflammatory markers would provide complementary prognostic information. This study aimed to develop and validate a nomogram combining these markers to predict postoperative overall survival (OS) in patients with resectable GC. This retrospective study included GC patients who underwent radical gastrectomy at Affiliated Changshu Hospital of Nantong University, between January 2017 and December 2022. Inclusion criteria included radical surgery without preoperative anticancer treatment, and expected postoperative survival \u22653 months. Exclusion criteria included concurrent or prior malignancies, preoperative infection, or use of lipid-altering medications within 6 months. Fasting venous blood samples were collected preoperatively for routine blood, lipid profile, and coagulation tests using standardized automated analyzers. Fourteen composite inflammatory and lipid indices were calculated. Univariate and multivariate Cox regression analyses identified the independent predictors of overall survival (OS). A nomogram was constructed and validated using Harrell's concordance index (C-index) and calibration curves. A total of 295 patients with GC were included in the study. The patients were randomized into a training group (n=197) and a validation group (n=98) (2:1 ratio). Baseline characteristics were well balanced (all P>0.05), with only alcohol consumption rate differing significantly between groups (P=0.01). Univariate and multivariate Cox regression revealed that the pathological tumor-node-metastasis (pTNM) stage [hazard ratio (HR) =2.05; 95% confidence interval (CI): 1.09-3.84; P=0.03], systemic immune-inflammation index (SII) (HR =1.99; 95% CI: 1.08-3.68; P=0.03), systemic inflammatory response index (SIRI) (HR =1.88; 95% CI: 1.02-3.45; P=0.04), and fibrinogen-to-platelet ratio (FPR) (HR =2.14; 95% CI: 1.25-3.67; P=0.006) were independent predictors of postoperative OS, positively correlating with postoperative mortality. The nomogram integrating these four variables showed satisfactory discriminative ability, with C-indices of 0.699 in the training set and 0.719 in the validation set. Calibration curves demonstrated good agreement between the predicted and observed 1-, 2-, and 3-year OS rates. The nomogram based on the pTNM stage, SII, SIRI, and FPR exhibits moderate prognostic performance for postoperative OS in GC patients. It provides a comprehensive tool for clinicians to assess prognosis, guiding adjuvant therapy and individualized follow-up strategies.",

This study aims to investigate the role of macrophage Dicer1 in skin wound healing in mice and to explore the regulatory mechanism underlying efferocytosis. Dorsal skin wounds were created in Dicer1-deficient and wild type mice, and the wound areas were quantified daily. In the wounds, epithelialization, granulation tissue growth, collagen deposition, angiogenesis, and the mRNA levels of inflammatory cytokines were measured and apoptotic cells were labelled. In vitro, macrophages were separated from the wounds, and the expressions of pentose phosphate pathway (PPP)-related molecules were measured; wound macrophages were cocultured with apoptotic Jurkat cells, then the phagocytosis was analyzed, and the mRNA levels of inflammatory cytokines and PPP-related molecules were measured in the macrophages. Macrophage-specific deletion of Dicer1 impairs skin wound healing in mice, resulting in delayed wound closure, reduced re-epithelialization and granulation tissue formation, diminished collagen deposition, and attenuated angiogenesis. Dicer1-deficient wounds exhibited sustained inflammation, alongside increased apoptotic cell accumulation. Mechanistically, Dicer1 knockout in macrophages led to impaired efferocytosis and upregulated PPP activity. These findings identify the Dicer1-PPP-efferocytosis axis as a critical regulator of macrophage function during wound repair. Our study provides novel insights into the molecular basis of impaired wound healing and suggests that targeting the macrophage Dicer1-PPP-efferocytosis axis may offer therapeutic potential for skin wounds.",
"42447970": "ID: 42447970\nTitle: Human umbilical cord-derived mesenchymal stem cells ameliorate muscle dysfunction and metabolic dysregulation in the CuZnSOD null mouse model of sarcopenia.\nAbstract: Age-related sarcopenia is a progressive skeletal muscle disorder driven by oxidative stress and metabolic dysregulation. Cu/Zn superoxide dismutase-deficient (Sod1-/-) mice recapitulate key features of oxidative stress-induced muscle degeneration and provide a robust preclinical model for mechanistic and therapeutic studies. Here, we investigated whether systemic administration of human umbilical cord-derived mesenchymal stem cells (UC-MSCs) could modulate muscle function and metabolic homeostasis under both pathological and physiological conditions. In Sod1-/- mice, UC-MSC treatment significantly improved motor coordination and grip endurance, restored gastrocnemius myofiber number, markedly reduced mitochondrial reactive oxygen species production and catalase expression levels in skeletal muscle, and restored muscle ATP content. UC-MSCs also restored circulating insulin-like growth factor-1 (IGF-1) levels. Untargeted lipidomic profiling revealed profound depletion of lipid species in Sod1-/- muscle, particularly omega-3 fatty acids, which was selectively rescued by UC-MSC therapy, including restoration of \u03b1-linolenic acid, eicosapentaenoic acid, and docosahexaenoic acid, without substantial recovery of disrupted polar metabolic pathways such as aminoacyl-tRNA biosynthesis. In contrast, UC-MSC administration in wild-type mice induced a distinct metabolic remodeling characterized by reduced n-3 and n-6 fatty acid-associated lipid species and concomitant enrichment of fructose-related glycolytic intermediates, indicating a shift toward carbohydrate-based energy utilization in metabolically intact muscle. Together, these findings demonstrate that UC-MSCs function as context-dependent metabolic modulators, alleviating oxidative stress-induced sarcopenia through attenuation of oxidative stress, restoration of systemic IGF-1, and selective reprogramming of lipid metabolism, while dynamically adjusting energy metabolism in physiological skeletal muscle.",

Beyond its established roles in glial development, lipid homeostasis, and circadian regulation, growing evidence positions FABP7 at the intersection of tumor metabolism, neuronal activity, and immune modulation in the brain. In this review, we integrate the physiological functions of FABP7 in glial cells with its tumor-intrinsic and microenvironmental roles in glioma. We summarize how gliomas co-opt FABP7-dependent metabolic, transcriptional, and post-transcriptional programs to promote stemness, lipid remodeling (e.g., altered fatty acid composition, lipid droplet formation, and lipid peroxidation resistance), inflammatory signaling, and invasive growth, including nuclear FABP7-mediated transcriptional activation linked to oncogene status. Furthermore, we discuss the role of FABP7 in shaping the tumor-neuro-immune interface, including regulating immunosuppressive gene networks, pro-tumoral macrophage polarization, resistance to T-cell-induced ferroptosis and immunotherapy, and tumor microtube-mediated integration into neuronal circuits to support glioma progression. Finally, we highlight therapeutic opportunities and challenges, including small-molecule FABP7 inhibitors, brain-directed delivery strategies, chronotherapeutic considerations, and combination approaches with immunotherapy. Collectively, this work positions FABP7-centered metabolic, circadian, and neuro-immune networks as potential vulnerabilities in glioma, linking fundamental glial biology to glioma therapeutics.",

The complex pathogenesis of DN has hindered the development of targeted therapies, creating an urgent need to develop novel strategies that directly address its underlying inflammatory and fibrotic mechanisms. Coreopsis tinctoria (CE) is an edible plant rich in polyphenols, but its mechanism against DN remains understood. An integrated framework combining network pharmacology and machine learning was developed to prioritize active polyphenols and their targets. A multi-layer perceptron classifier, trained on 3.16 million compound-target pairs from Binding DB, predicted interactions between 36 CE polyphenols and 12,030 DN-associated genes. The top 100 targets were subjected to KEGG enrichment analysis, and the identified pathways were validated in a high-fat diet/STZ-induced DN rat model. The MLP model achieved superior performance (AUC-ROC = 0.9219, AP = 0.9592). Five lead polyphenols (flavonoids/chalcones) showed high predicted activity. KEGG analysis revealed enrichment in PI3K-Akt, calcium signaling, metabolic pathways, and cellular senescence. In vivo, CE treatment (150-600 mg/kg/day) dose-dependently improved glucose/lipid metabolism and renal function, and ameliorated histopathological damage, including glomerular hypertrophy, fibrosis, and mesangial expansion. Mechanistically, CE suppressed NF\u03baB/TGF\u03b2/Smad signaling, restored PPAR\u03b3 and Nrf2/HO-1/FoxO1 antioxidant defenses, and inhibited apoptosis via Bcl-2/Bax regulation. CE exerts multi-target renoprotective effects through coordinated modulation of metabolic, inflammatory, fibrotic, and antioxidant pathways, supporting its potential as a functional food ingredient for DN management.",

These compounds have the potential to enhance product safety and shelf life while meeting consumer expectations. Many natural bioactives exhibit antioxidant and antimicrobial activities, enabling them to reduce lipid oxidation and inhibit the growth of spoilage and pathogenic microorganisms in meat systems. Despite these benefits, their practical application remains limited by instability, volatility, poor solubility, and undesirable sensory effects. Encapsulation technologies have emerged as effective approaches to overcome these limitations by enhancing stability, controlling release behavior, and improving compatibility with complex meat matrices. This review synthesizes evidence from 154 studies published between 2010 and 2026 on the application of encapsulation technologies, including microencapsulation, nanoemulsions, liposomes, and cyclodextrin-based systems, for natural bioactives in meat systems. Encapsulated bioactive delivery systems are evaluated by integrating spoilage mechanisms, delivery system design, and application strategies. Encapsulation approaches are discussed in terms of structure-function relationships, release behavior, and interactions with meat components. Application strategies, including direct incorporation, edible coatings, and active packaging, are comparatively analyzed based on their functional performance in meat systems. Overall, nanoscale delivery systems are particularly effective in improving the dispersion, stability, and functional performance of hydrophobic bioactives, while controlled-release systems offer prolonged protection but often exhibit reduced predictability when translated from model systems to real meat matrices. Current challenges related to scalability, cost, regulatory constraints, sensory impact, industrial implementation, and the safe design of sustained-release antimicrobial systems are also addressed, thereby providing a framework for the rational development and implementation of effective clean-label preservation strategies in meat systems.",
"42451146": "ID: 42451146\nTitle: Dietary Polysaccharides and the Regulation of Blood Glucose and Lipid Parameters-A Narrative Review.\nAbstract: The increase in the prevalence of non-communicable diseases globally has been attributed in part to poor lifestyle choices, including unhealthy dietary habits. Dietary polysaccharides, including resistant starch and non-starch polysaccharides, have gained increasing attention due to their potential role in the regulation of glucose and lipid metabolism. Therefore, the aim of this review was to evaluate the role of dietary polysaccharides in the regulation of blood glucose and lipid parameters. A narrative review approach was adopted for this review. Searches were conducted through EBSCOHost and involved the following databases: Medline, APA PsycInfo, CINAHL Plus with Full Text, Psychology and Behavioural Sciences collection, Academic Search Premier and APA PsycArticles. Searches were conducted on 14 April 2026 and covered all records available from database inception to the search date. Search terms were combined using Boolean operators (AND/OR). The reference list of articles was also searched for more articles. Twenty-one studies from thirteen different countries were included in this review. Based on narrative synthesis, five themes were identified: the effects of dietary polysaccharides on glycaemia, insulin, lipids, energy intake and satiety/appetite. The findings demonstrated considerable heterogeneity across studies. While several studies reported improvements in fasting glucose, postprandial glucose, glycated haemoglobin and insulin responses following resistant starch and non-starch polysaccharide interventions, other studies found no significant effects on glycaemic control or insulin levels. Lipid outcomes were similarly inconsistent, although some studies reported reductions in total cholesterol and low density lipoprotein cholesterol. Effects on energy intake and satiety varied according to the type and physicochemical characteristics of the polysaccharide investigated. The findings of this review suggest that dietary polysaccharides may contribute to improvements in glucose control and lipid metabolism, although the magnitude and consistency of these effects vary across populations, intervention types and study designs. The most frequently reported beneficial findings related to blood glucose parameters, although substantial heterogeneity remained across studies. Further, well-designed studies, including randomised controlled trials with longer durations, are needed to fully establish the role of dietary polysaccharides in the control of blood glucose and lipid parameters.",
"42451149": "ID: 42451149\nTitle: MELHAC Improves Glucose and Lipid Metabolism in HFD + Alloxan-Induced Mice.\nAbstract: Background: Glucose and lipid metabolism disorders are characterized by hyperglycemia, dyslipidemia, hepatic oxidative stress, lipid accumulation, and gut microbiota dysbiosis, all of which contribute to progressive metabolic dysfunction and tissue injury. As a plant extract mixture derived from mulberry leaves, lotus leaves, and Eucommia leaves, MELHAC (Mulberry-Eucommia-Lotus Herbal Aqueous Complex) was developed as a medicinal and edible formula with potential multi-component metabolic regulatory activity. In the present study, we systematically evaluated the effects of MELHAC on glucose and lipid metabolic abnormalities in high-fat diet (HFD) plus alloxan-induced mice. Methods: The phytochemical profile of MELHAC was characterized using untargeted LC-MS and network pharmacology. Its metabolic effects were evaluated in HFD plus alloxan-induced mice by measuring fasting blood glucose, serum lipid parameters, glucose tolerance, hepatic oxidative stress markers, histopathological changes, hepatic lipid accumulation, gut microbiota composition, and preliminary safety indices. Results: Chemical characterization revealed that MELHAC contains abundant bioactive constituents dominated by flavonoids, phenolic acids and alkaloids. In vivo experiments demonstrated that MELHAC lowered fasting blood glucose, total cholesterol and triglyceride levels, while ameliorating glucose intolerance and pathological damage in the liver, kidney and pancreas. MELHAC also improved liver-related biochemical abnormalities, increased hepatic superoxide dismutase, decreased malondialdehyde, and reduced hepatic lipid accumulation, indicating protective effects against oxidative stress and steatosis associated with metabolic dysfunction. In addition, MELHAC modulated gut microbial community structure and differential taxa linked to metabolic homeostasis. Short-term high-dose administration did not cause obvious abnormalities in serum biochemical, hematological, or histopathological indices. Conclusions: These findings suggest that MELHAC has potential as a plant-derived functional ingredient for improving glucose and lipid metabolic disorders and may provide an experimental basis for the future development of functional foods targeting metabolic health.",

Although serum 25-Hydroxyvitamin D (25(OH)D) has been implicated in lipid metabolism, findings in children remain inconsistent, and whether these associations differ by overweight/obesity (ow/ob) status is unclear. We therefore aimed to investigate the associations of serum 25(OH)D concentrations and lipid profiles stratified by ow/ob status among children and adolescents aged 9-17 years. Methods: This cross-sectional study included 3067 children and adolescents from Guangzhou, southern China. Anthropometric measurements were obtained by trained staff, and ow/ob status was classified according to WHO criteria. Fasting blood samples were collected to measure serum 25(OH)D and lipid parameters. Multivariable regression analyses were adopted to determine the associations between serum 25(OH)D and lipid profiles. Stratified analysis and interaction tests were further applied according to ow/ob status. Results: Higher 25(OH)D concentrations were most consistently associated with lower TG (\u03b2 = -0.026; 95% CI, -0.040 to -0.011), higher HDL-C (\u03b2 = 0.025; 95% CI, 0.014 to 0.035), and lower TG/HDL-C ratios (\u03b2 = -0.044; 95% CI, -0.061 to -0.027). Positive associations were also observed for TC, LDL-C, and non-HDL-C with serum 25(OH)D, but these were attenuated after further adjustment for HDL-C. No significant association was observed for the TC/HDL-C ratio. In stratified analyses, associations with several lipid parameters were observed mainly among children and adolescents without ow/ob, whereas significant inverse associations among those with ow/ob were largely limited to TG and the TG/HDL-C ratio. Significant interactions between vitamin D and ow/ob status were observed for TC and non-HDL-C, but were attenuated after further adjustment for HDL-C. Conclusions: In this cross-sectional study, serum 25(OH)D was associated with several lipid parameters among children and adolescents, most consistently with TG, HDL-C, and the TG/HDL-C ratios. Stratified analyses showed different vitamin D-lipid association patterns across ow/ob status, with statistically significant interactions observed only for TC and non-HDL-C. The attenuation of several associations after adjustment for HDL-C suggests that HDL-C may be involved in these observed patterns. Future longitudinal studies are needed to examine causality of vitamin D-lipid associations and the potential role of HDL-C in these associations.",

While the WW domain-containing E3 ubiquitin ligase1 (WWP1) is an essential mediator of dietary restriction-induced longevity in Caenorhabditis elegans, its role in mammalian CR remains unclear. In this study, we investigated the role of WWP1 in CR-mediated longevity and metabolic adaptation using systemic Wwp1 knockout (KO) mice. Male wild-type (WT) and Wwp1 KO mice were subjected to either ad libitum (AL) feeding or long-term CR (70% of AL intake) and monitored throughout their natural lifespan. As a result, Wwp1 deficiency did not markedly modify the CR-associated survival response in mice. Despite comparable food intake, CR-Wwp1 KO mice after middle age exhibited a modest increase in body weight compared with CR WT mice. WWP1 deficiency selectively enhanced CR-induced, Srebp-1c-dependent expression of proteins involved in de novo fatty acid synthesis in epididymal WAT, whereas hepatic lipid metabolism was unaffected. Collectively, our results demonstrated that, unlike in C. elegans, WWP1 is not required for CR-induced longevity in mammals; rather, it acts as a partial suppressor of CR-driven de novo fatty acid metabolism, limits energy storage and lipid retention in WAT.",

How peroxisomes coordinate protein import and support metabolic functions across complex tissues and timescales remains poorly understood in vivo. Using the Drosophila brain, we discover a striking enrichment of peroxisomes in the neuronal soma and the cortex glia that enwrap them. Unexpectedly, import of peroxisomal proteins into cortex glia, but not neurons, oscillated across time and peaked in the early morning. Rhythmic peroxisomal import in cortex glia autonomously required the circadian clock and Peroxin 5 (Pex5; peroxisomal biogenesis factor 5 homolog), with import persistently elevated in clock mutants. Notably, reducing Pex5 in cortex glia, but not neurons, caused hyperactivity and reduced total sleep. Moreover, brain lipid metabolism was dramatically altered upon Pex5 knockdown, with glia impacting sphingolipids and triacylglycerols, and neurons impacting phospholipids. The cell-type specificity of these Pex5 phenotypes highlights unique roles for peroxisomal import in both sleep and lipid metabolism in the brain.",

Disruption of this balance may contribute to gestational diabetes mellitus (GDM), a condition increasingly recognized as metabolically heterogeneous. Whether early-pregnancy glucose-lipid indices capture this heterogeneity and extend to hypertensive disorders of pregnancy (HDP) remains unclear. This retrospective multicenter cohort included 13,419 pregnancies (11,765 singleton and 1,654 twin pregnancies). Fasting glucose and lipid measurements obtained at 5-16\u00a0weeks of gestation were used to derive eight composite indices, including the triglyceride-glucose (TyG) index, TyG-BMI, METS-IR, SPISE, AIP, CHG, NHHR, and lnRC. Multinomial logistic regression evaluated associations with GDM subtypes (post-load, isolated fasting, and combined GDM), using normoglycemia as the reference. Extension analyses assessed GDM-HDP phenotypes (GDM-only, HDP-only, and combined GDM-HDP) relative to normoglycemic-normotensive pregnancies. Restricted cubic spline models examined dose-response relationships, and receiver operating characteristic analyses assessed discriminative performance. Early-pregnancy glucose-lipid indices showed a clear gradient across GDM subtypes, with progressively stronger associations from post-load GDM to isolated fasting GDM and combined GDM; adjusted odds ratios (ORs) per unit increase in TyG index were 2.54, 6.21, and 8.91, respectively. When analyses were extended to hypertensive outcomes, the strongest association was observed for combined GDM-HDP (adjusted OR, 4.81; 95% confidence interval, 3.35-6.89). Significant interaction with prepregnancy overweight status was observed for TyG-BMI, with more pronounced heterogeneity across HDP-related phenotypes, whereas associations were directionally similar across singleton and twin pregnancies after accounting for center composition. For the highest-risk phenotypes, area under the curve (AUC) values were 0.786 for combined GDM (TyG index and TyG-BMI) and 0.811 for combined GDM-HDP (TyG-BMI). A significant interaction between fasting glucose and high-density lipoprotein cholesterol was detected for both combined GDM (interaction OR 3.61) and combined GDM-HDP (interaction OR 3.79). Early-pregnancy glucose-lipid indices are associated with a graded pattern of metabolic heterogeneity across GDM subtypes, and a similar pattern is observed for hypertensive comorbidity. These findings are consistent with shared metabolic perturbations underlying glycemic and vascular complications during pregnancy and may inform future approaches to early-pregnancy risk assessment.",

Male C57BL/6J mice were fed control or HFD diets, with or without 2% SL supplementation, for 12 weeks. HFD feeding markedly increased the body weight, hepatic steatosis, insulin resistance, dyslipidemia, inflammation, and oxidative stress and altered hepatic gene expression. SL supplementation significantly attenuated weight gain without affecting the energy intake, reduced hepatic steatosis and adiposity, and improved glucose homeostasis. Serum triglycerides, total cholesterol, LDL-cholesterol, and transaminase activities were normalized, while pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6) and oxidative stress markers were reduced. The antioxidant capacity was restored, with normalization of SOD, CAT, GPX, and GR activities. At the transcriptional level, SLs reactivated PPAR-\u03b1 signaling, enhanced CPT-I and ACOX expression, and suppressed lipogenic genes (SREBP-1c, ACC, FAS), thereby promoting fatty acid oxidation and attenuating lipogenesis. Desaturase activities (\u03945D, \u03946D) were modulated, improving n-6/n-3 ratios in liver and adipose tissue, with tissue-specific responses observed in the brain. Dietary GLA- and SDA-enriched 1,3-DAGs reprogrammed lipid metabolism, mitigated HFD-induced metabolic dysfunction, and enhanced PUFA profiles, exerting protective effects against obesity-related dyslipidemia, oxidative stress, and inflammation. These findings highlight their potential as functional lipids for nutritional strategies targeting obesity and metabolic disorders.",
"42461367": "ID: 42461367\nTitle: Lipidomics and proteomics in MASLD: reading the molecular script toward precision therapeutics.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) is increasingly recognized as a multisystem disorder characterized by complex metabolic, inflammatory, and fibrogenic interactions. Advances in lipidomics and proteomics have substantially refined understanding of MASLD pathophysiology by revealing how qualitative alterations in lipid species and dynamic protein signaling networks contribute to disease initiation and progression. Bioactive lipids, including ceramides and free cholesterol, promote lipotoxicity, mitochondrial dysfunction, inflammasome activation, and fibrosis, while proteomic analyses have identified key pathways involved in inflammation, cellular senescence, and hepatic stellate cell activation. Emerging translational evidence further suggests that modern pharmacological agents may modulate these molecular signatures beyond their metabolic effects. Integrating lipidomic and proteomic data may therefore facilitate improved disease stratification, biomarker discovery, and the development of mechanism-based therapeutic strategies, supporting a transition toward precision medicine in MASLD.",

Here, we identify tissue-resident macrophages (TRMs) as central coordinators of age-related organ decline through impaired clearance of senescent neutrophils, a process regulated by the immunomodulatory prostaglandin E2 (PGE2) receptor EP2. Reducing TRM EP2 signaling in aged mice preserved youthful mitochondrial fitness and prevented cognitive decline, frailty, sarcopenia, adiposity, cardiac impairment, and systemic inflammation. Plasma proteomics implicated the liver as a major source of age-associated immune change, in which reduced TRM EP2 signaling rescued neutrophil efferocytosis and prevented paracrine stress in neighboring cells. Elevated TRM EP2 expression and senescent neutrophils were also observed in aged and diseased human tissues. Pharmacologic EP2 inhibition restored youthful neutrophil clearance, establishing impaired TRM efferocytosis as a reversible driver of organ decline in aging.",
"42463009": "ID: 42463009\nTitle: Neuronal ketone body utilization couples exercise and time-restricted feeding to cognitive enhancement.\nAbstract: Ketone body metabolism is linked to brain health benefits, including delaying age-related cognitive decline. Exercise, particularly when combined with an overnight fast, stimulates ketone body turnover and improves brain metabolism and cognition. Yet, whether ketone metabolism is obligatory for this response is unknown. Here, we use chronic exercise via voluntary wheel running plus time-restricted feeding (VWR + TRF) to explore whether ketones mediate exercise-induced brain health benefits in middle-aged mice. To distinguish the roles of neuronal ketone metabolism vs. hepatic ketone production, we studied middle-age female neuronal-specific SCOT knockout mice and hepatocyte-specific HMGCS2 knockout mice, respectively. VWR + TRF was compared to sedentary ad-libitum fed mice to assess the impact on whole-body metabolism, cognition, and hippocampal molecular adaptations. VWR + TRF upregulated systemic lipid oxidation in all mice during the fasting period. In female SCOT-Neuron-KO mice, we show impaired responses to VWR + TRF in indices of short- and long-term memory. Proteomic analysis of isolated hippocampi revealed that SCOT-Neuron-KO mice failed to globally upregulate key facilitators of synaptic function, including leucine-rich repeated transmembrane proteins, neurexins, and neuroligins. In female HMGCS2-Liver-KO mice, impaired responses to VWR + TRF in indices of short-term memory were paired with an upregulation in hippocampal ketogenesis machinery, suggesting potential in vivo evidence of cerebral ketogenesis, a mechanism mitigating an otherwise more pronounced behavioral phenotype. Together, these findings suggest that neuronal ketone body utilization is essential for, while hepatic-derived ketone bodies contribute to, the full cognitive and synaptic adaptations to VWR + TRF, supporting ketone metabolism as a key mechanistic link between metabolic state and brain health in midlife.",
"42464312": "ID: 42464312\nTitle: Synergistic effect of AIP and cystatin C: a study on cardiovascular risk prediction in populations with different glycemic statuses.\nAbstract: Cardiovascular disease (CVD) poses a major global health burden. The Atherogenic Index of Plasma (AIP) and Cystatin C are novel biomarkers reflecting lipid metabolism disorders and renal/micro-inflammatory status, respectively. Their combined indicator (AIP-Cys, the product of AIP\u2009\u00d7\u2009Cystatin C) may provide improved predictive value beyond either marker alone. This study aimed to investigate the predictive role of AIP-Cys for the risk of incident CVD across different glycemic statuses: normal glucose regulation (NGR), pre-diabetes (preDM), and diabetes mellitus (DM). This study was based on the prospective China Health and Retirement Longitudinal Study (CHARLS) cohort. A total of 6,035 participants aged\u2009\u2265\u200945 years without a history of CVD at baseline (2011) were included. The primary exposure was baseline AIP-Cys (the product of AIP\u2009\u00d7\u2009Cystatin C), and the outcome was the first self-reported incident heart disease or stroke event during follow-up (until 2020). Glycemic status was defined based on fasting plasma glucose and glycated hemoglobin levels. Multivariable Cox proportional hazards models were used to estimate hazard ratios (HRs). Restricted cubic splines and piecewise linear models were applied to analyze nonlinear relationships. Mediation and sensitivity analyses were conducted to verify the robustness of the results. During a median follow-up of 9.0 years, 651 incident CVD cases occurred. In the fully adjusted model, AIP-Cys was independently associated with CVD risk in the overall (HR per unit increase: 1.34; 95% CI: 1.06-1.69), NGR (HR: 1.60; 95% CI: 1.13-2.26), and preDM (HR: 1.32; 95% CI: 1.02-1.70) populations, but not in the DM population. RCS analysis revealed a significant nonlinear relationship in the NGR and preDM groups (P for nonlinearity\u2009<\u20090.05). Piecewise regression identified inflection points (0.47 for NGR; 0.37 for preDM), below which risk increased sharply. Quartile analysis showed the highest risk in Q3 rather than Q4, suggesting a saturation effect. Mediation analysis indicated that systolic blood pressure partially mediated this association (mediating proportion: 14.6% in overall population). The predictive performance of AIP-Cys was modest for short-term risk (1-year AUC: 0.64-0.67) but limited for long-term prediction. The composite indicator AIP-Cys, derived from AIP and Cystatin C, is an independent risk factor for incident CVD in individuals with NGR and preDM. The association exhibits a nonlinear threshold pattern. However, its predictive value is limited in the DM population, and its long-term predictive performance is modest. Additionally, the self-reported nature of cardiovascular outcomes represents a limitation that should be considered when interpreting these findings. By integrating lipid metabolism and renal/inflammatory pathways, this indicator offers a novel biomarker-based approach for early cardiovascular risk identification in the pre-diabetes stage. Future research should further explore its potential for clinical translation and intervention.",
"42468599": "ID: 42468599\nTitle: Mechanically adaptive hydrogels reprogram apoptotic cell clearance to prevent tissue fibrosis.\nAbstract: Abnormal mechanical stimulation drives fibrotic scar formation in active wounds by sustaining mechanotransduction, promoting apoptotic cell accumulation and pro-fibrotic amplification that constrain functional regeneration. To address this challenge, we developed a mechanically adaptive hydrogel patch (Gel/VP) through the integration of an interpenetrating polymer network and CNC@PDA@ZIF8 dynamic nanofillers, in which the interpenetrating network provides structural load-bearing and adaptive deformation, while the nanofillers form a force-induced, reconfigurable dissipative network via hydrogen bonding and \u03c0-\u03c0 interactions, collectively dissipating tensile energy upon pre-stretched application, establishing a reverse mechanical buffer at the wound interface, suppressing sustained Piezo1-YAP activation, restoring macrophage efferocytosis-mediated apoptotic cell clearance, and ultimately limiting fibrotic scar formation. The interpenetrating architecture endows the patch with a tunable elastic window matched to the mechanical environment of skin (elastic modulus of 7-15 kPa with twofold extensibility). Under reverse mechanical buffering, the macrophage phagocytic rate increases from 22.50% to 64.50%, significantly enhancing apoptotic cell clearance. In vivo, the patch achieves near-complete wound closure (>95%) within two weeks, markedly reduces \u03b1-SMA+ myofibroblast accumulation, promotes ordered collagen remodeling, and substantially decreases scar formation. Overall, by leveraging material-mediated reverse stress buffering to restore macrophage efferocytosis, this study targets apoptotic cell clearance at an early stage of fibrosis and provides a robust antifibrotic material strategy for the functional regeneration of active wounds. STATEMENT OF SIGNIFICANCE: Abnormal mechanical stretching during wound healing is a key yet underrecognized driver of fibrotic scar formation, and current therapies rarely address this physical cue. Here, we develop a stress-adapted hydrogel patch that forms a \"reverse mechanical buffer\" under pre-stretch, actively redistributing tensile forces at the wound interface. This buffering suppresses mechanotransduction (Piezo1-YAP signaling) while restoring macrophage-mediated clearance of apoptotic cells. By integrating an interpenetrating polymer network with dynamic nanofillers, the material achieves adaptive energy dissipation and mechanical compatibility with skin. This work establishes a mechanically guided, immunomodulatory approach to limit fibrosis, offering a promising biomaterials strategy for scarless healing and functional tissue regeneration.",
"42468854": "ID: 42468854\nTitle: Beta-2-microglobulin augments neutrophil phagocytosis of bacteria and apoptotic cells.\nAbstract: Polymorphonuclear leukocytes (PMNs), predominantly neutrophil granulocytes, are key components of the innate immune system that eliminate invading pathogens through phagocytosis and clear apoptotic cells through efferocytosis. Beta-2-microglobulin (\u03b22m) is best known as the light chain of major histocompatibility complex class I (MHC I), where it is required for antigen presentation to CD8\u207a T cells. However, emerging evidence suggests that extracellular \u03b22m may also regulate innate immune responses. Here, we show that extracellular \u03b22m enhances neutrophil phagocytosis and efferocytosis. Addition of soluble \u03b22m (50 \u00b5g/ml) increased phagocytosis of latex beads by PMNs from 23% to 31%, whereas the proteolytically cleaved variant desLys58-\u03b22m (dK58\u03b22m) had no effect. In contrast, both \u03b22m and dK58\u03b22m enhanced phagocytosis of the Gram-positive bacterium Streptococcus pyogenes and the Gram-negative bacterium Acinetobacter baumannii by >3.6-fold. Furthermore, both \u03b22m variants promoted efferocytosis of apoptotic Jurkat cells in a dose-dependent manner, resulting in up to a two-fold increase that was comparable to the effect of GM-CSF. Cytochalasin D abolished \u03b22m-mediated uptake of apoptotic cells. Pre-incubation of latex beads with \u03b22m followed by washing did not enhance phagocytosis, and pre-incubation of PMNs with \u03b22m followed by washing did not enhance subsequent efferocytosis of apoptotic cells. These findings indicate that \u03b22m does not act by coating phagocytic targets or by inducing sustained neutrophil priming. Collectively, these findings identify extracellular \u03b22m as a regulator of neutrophil-mediated phagocytosis and efferocytosis and demonstrate that proteolytic processing differentially influences these activities.",

The thermal stability and degradation of myricetin in a simplified palmitic acid model under frying-relevant conditions was investigated. Myricetin degraded rapidly at 180 \u00b0C but remained relatively stable at 120 \u00b0C. UPLC-QTOF-MS/MS, supported by density functional theory calculations, suggested that myricetin transformation is temperature-dependent but primarily governed by lipid oxidation-derived radical and carbonyl chemistry. Vitamin C markedly delayed myricetin degradation by suppressing radical initiation and limiting o-quinone-centered downstream reactions. These findings highlight lipid oxidation as a key determinant of polyphenol stability during frying and clarify the protective role of antioxidants in lipid-rich thermal processing systems.",

This study evaluated the effects of Lacticaseibacillus paracasei in a murine model of high-fat diet (HFD)-induced obesity. Oral administration of L. paracasei significantly reduced body weight gain and adiposity without altering food intake, indicating improved energy efficiency. Probiotic supplementation enhanced insulin sensitivity and glucose tolerance, as shown by lower fasting glucose, insulin levels, and HOMA-IR. At the molecular level, L. paracasei downregulated adipogenic genes (Srebf1, Pparg, Cebpa, Fabp4) and upregulated Ucp-1, suggesting increased browning of white adipose tissue. Inflammatory markers (Tnf-\u03b1, Il-6, Mcp-1) and JNK pathway activation were decreased, while insulin signaling and lipid metabolism improved via increased Glut4 and Ppar\u03b1, and modulation of adipokines. In the liver, the probiotic attenuated steatosis, reduced oxidative stress, and modulated genes related to lipid metabolism. Gut barrier integrity was improved, as indicated by higher expression of tight junction proteins, lower LPS levels, and reduced Tlr4 expression. L. paracasei also reshaped the gut microbiota, decreasing the Bacillota/Bacteroidota ratio and increasing beneficial taxa such as Akkermansia muciniphila and Lactobacillus, while reducing Clostridium spp. Additionally, it normalized obesity-associated miRNAs involved in adipogenesis and inflammation. Finally, the probiotic improved endothelial function and reduced vascular oxidative stress. These results support L. paracasei as a promising probiotic for obesity management, acting through metabolic, inflammatory, and microbiota-mediated mechanisms.",

This interventional, randomized controlled clinical study aims to explore the efficacy of EA treatment in maintenance haemodialysis (MHD) patients with sarcopenia. Thirty-six participants with sarcopenia undergoing MHD were randomly divided into the control group and the EA group. The participants in the EA group received a total of 24 treatments, each lasting 30\u2009min, and were administered three times per week. Participants in the control group were instructed to continue their current lifestyle and treatment plans. The assessments were conducted at baseline and after 8\u2009weeks.

Repeated measures analysis of variance (ANOVA) was used to assess EA effects, reporting main effects and the time\u2009\u00d7\u2009group interaction with partial eta squared (\u03b72p) effect sizes. The primary outcome was 6-m gait speed; the secondary outcomes were skeletal muscle mass index (SMI) and handgrip strength. Fasting blood samples were collected, and serum metabolomics using the liquid chromatography-mass spectrometry method was employed to reveal metabolic changes. One participant from the EA group dropped out, and 35 participants were included in the analysis, aged (59.06\u2009\u00b1\u200911.69) years, including 22 men and 13 women.

Tumors actively exploit lipid mediators, notably prostaglandin E2 (PGE2), to suppress CD8+ T cells and promote immunosuppressive macrophage polarization. Although targeted nanotherapeutics aim to locally reverse these defects, their in vivo efficacy is frequently abrogated by the host's nutritional baseline. Specifically, high dietary intake of Omega-6 polyunsaturated fatty acids fuels systemic PGE2 biosynthesis, creating a metabolic \"sink\" that localized nanotherapies struggle to neutralize. To address this limitation, this review proposes a dual-compartment therapeutic framework combining systemic dietary modulation with precision nanotherapy. As a distinctive contribution, we bridge these biological mechanisms with pharmaceutical design by integrating critical translational barriers, advanced formulation strategies, and emerging technologies for lipid reprogramming. Building upon this, we critically evaluate the most promising formulations, including stimuli-responsive and lipid-targeted nanocarriers, to elucidate their synergistic potential with nutritional interventions. Ultimately, pairing systemic Omega-3 dietary preconditioning with localized nanotherapeutics provides a biologically rational strategy to dismantle lipid-driven immune evasion. Maximizing patient outcomes and advancing future clinical prospects will depend on the rigorous translation of these combinatorial regimens to effectively overcome ICI resistance.",

Betalains, primarily derived from Beta vulgaris, exhibit notable antidiabetic and anti-obesity properties, highlighting their therapeutic potential. This systematic review evaluates the antidiabetic and anti-obesity effects of betalains based on in vitro and in vivo evidence. Literature published between 2015 and 2025 was retrieved from PubMed, ScienceDirect, Scopus, Web of Science, and Google Scholar. Eligible studies assessed betalains effects on glucose and lipid metabolism, while reviews and irrelevant reports were excluded. Out of 508 identified studies, only 12 met the inclusion criteria. The systematic review was registered in PROSPERO under ID 1357942. Risk of bias was assessed using the OHAT tool for in vitro studies and the SYRCLE tool for animal studies. Betalains demonstrated significant metabolic benefits by reducing triglyceride accumulation, fasting blood glucose, insulin resistance, and NF-\u03baB activation, while increasing insulin, adiponectin, and HDL-C levels. They also downregulated total cholesterol, LDL-C, and lipogenic markers (PPAR\u03b3, SREBP-1c). Overall, betalains show potential as natural agents against diabetes and obesity; however, well-designed clinical trials with standardized dosing are needed to confirm long-term efficacy.",
"42479460": "ID: 42479460\nTitle: Efferocytosis activates a DNMT3A-mediated oxidized DNA repair pathway to enable tissue resolution.\nAbstract: Efferocytosis, the clearance of apoptotic cells by macrophages, promotes tissue resolution. Efficient resolution requires efferocytosis-induced macrophage proliferation (EIMP) to expand pro-resolving macrophages. Here, we show that efferocytosis activates base excision repair (BER) to remove 8-OHdG from DNA, enabling EIMP. Mechanistically, efferocytosis promotes poly(ADP-ribose) polymerase-1 (PARP1) chromatin binding and PARylation to facilitate DNA repair complex assembly, and increases nuclear MTH1/NUDT1, which hydrolyzes 8-OHdG. Both processes require DNA-methyltransferase-3A (DNMT3A), which is activated during efferocytosis. Using a model where dexamethasone-induced thymocyte apoptosis triggers efferocytosis-mediated thymic repair, we showed that DNMT3A is required for increases in nuclear PARP1/MTH1, oxidized DNA suppression, EIMP in thymic macrophages, and thymic repair. We next studied a human-relevant model of atherosclerosis regression, where efferocytosis drives protective lesional fibrous cap thickening. We compared WT mice with a model of DNMT3A-clonal hematopoiesis (CH), in which loss-of-function DNMT3A mutations promote atherosclerotic disease. Atherosclerosis regression in WT mice led to decreased nuclear 8-OHdG and increases in nuclear PARP1/MTH1 and EIMP in lesional macrophages and fibrous cap thickening, all of which were impaired in DNMT3A-CH regression. These findings reveal that efferocytosis initiates a BER pathway to allow macrophage proliferation for tissue resolution, with possible therapeutic relevance to atherosclerosis regression and DNMT3A-CH.",

This study investigated the radiosensitizing effects of either 7-day 30% caloric restriction (CR) or 24-hour fasting in a murine model bearing CT-26 colorectal tumor and explored the underlying mechanisms. CR and fasting pretreatment enhanced irradiation-induced tumor apoptosis, mitochondrial dysfunction, and cytosolic DNA stress, leading to activation of the cyclic GMP-AMP synthase/stimulator of interferon gene (cGAS-STING) pathway, increased infiltration of tumor killing-associated CD8\u2009+\u2009cytotoxic T lymphocytes, and modulation of macrophage polarization toward an antitumor phenotype. In addition, CR and fasting further suppressed the expression of glycolysis and lipid metabolism related proteins in the tumor microenvironment upon radiation exposure. By contrast, CR and fasting protected normal intestinal tissue from irradiation-induced damage. These findings were validated in vitro using CT-26 and normal small intestinal epithelial cells (IEC-6) cultured under medium with or without glucose. The critical role of the cGAS-STING pathway in enhancing radiosensitivity was confirmed through STING siRNA-mediated knockdown, combined with pharmacological intervention using the STING agonist MSA-2 and inhibitor H-151.

We combined single-cell RNA sequencing of elastase-induced murine AAA with pathway, cell-cell communication, trajectory, and regulon analyses, and validated key findings in vivo by immunostaining and flow cytometry and in vitro by pharmacologic ERK inhibition, gene-expression analysis, and macrophage efferocytosis assays. Single-cell transcriptomic analysis identified four macrophage subsets in AAA, comprising Thbs1+Spp1+ inflammatory macrophages, Mrc1+Gas6+ efferocytosis-associated macrophages, Cdca8+ proliferative macrophages, and Cd36+Lpl+ lipid-handling macrophages. AAA progression was characterized by expansion of Thbs1+Spp1+ macrophages and emergence of Cdca8+ macrophages, together with relative loss of Mrc1+Gas6+ and Cd36+Lpl+ macrophages. Thbs1+Spp1+ macrophages showed inflammatory, chemotactic, oxidative stress, and metabolic remodeling signatures, whereas Mrc1+Gas6+ macrophages were enriched for efferocytosis- and homeostasis-associated features but exhibited increased apoptosis-related signals and reduced expression of Mertk, Gas6, and Igf1 during AAA progression. ERK signaling was overactivated in AAA and associated with loss of these effectors and impaired macrophage efferocytosis, whereas ERK inhibition restored Mertk, Gas6, and Igf1 expression and enhanced uptake of apoptotic cells in macrophage-line models. Trajectory and regulon analyses further suggested that inflammatory and efferocytosis-associated macrophages follow distinct state trajectories, with Maf emerging as a candidate regulator of the Mrc1+Gas6+ program. AAA is characterized by an imbalance between inflammatory and efferocytosis-associated macrophage states. ERK-associated dysfunction of Mrc1+Gas6+ macrophages may contribute to defective inflammation resolution and represents a potential therapeutic target in aneurysmal disease.",

A systematic search of the PubMed, Web of Science, Cochrane Library and Embase databases (from the inception of each database to 16 November 2025) identified a total of 21 randomized controlled trials involving 792 participants. A pooled analysis was conducted using standardized mean differences (SMD) and 95% confidence intervals. The results showed no significant differences between HIIT and MICT in terms of glycated hemoglobin (HbA1c), fasting blood glucose, HOMA-IR, body mass index (BMI), total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL) or blood pressure. However, HIIT demonstrated a significant advantage in improving high-density lipoprotein cholesterol (HDL) (SMD 0.44, p = 0.023). Subgroup analyses indicated that moderate training duration (20-30 minutes), lower weekly training frequency (\u22643 sessions) and shorter intervention duration (\u22648 weeks) optimized the benefits of HIIT on HDL. These findings suggest that HIIT is an effective alternative to MICT for patients with type 2 diabetes, particularly those with time constraints and whose primary metabolic abnormality is characterized by low HDL levels. Personalized exercise prescriptions should consider training duration and weekly training frequency as key modifiers. https://www.crd.york.ac.uk/PROSPERO/, identifier CRD420261343976.",
"42486499": "ID: 42486499\nTitle: The triple-hit hypothesis: exploring pulmonary e-cigarette, PM2.5 and viral polyexposure.\nAbstract: Exposure to e-cigarette aerosols, particulate matter with aerodynamic diameter \u22642.5 \u00b5m (PM2.5) and respiratory viruses rarely occurs in isolation, but rather in complex polyexposure contexts during daily life. On a cellular and molecular level, vaping induces a distinct lipid-laden macrophage phenotype, alters pulmonary neutrophilic infiltration and impairs epithelial differentiation and ciliary function. In contrast, PM2.5 alters the macrophage polarisation equilibrium, temporally favouring an acute pro-inflammatory phenotype and a subsequent chronic tissue-remodelling phenotype, while also driving an oxidative inflammatory epithelial milieu. Both exposures thus impair antiviral defences and enhance susceptibility to respiratory viral infections such as influenza A, rhinovirus and severe acute respiratory syndrome coronavirus 2. The triple-hit hypothesis proposes that concurrent exposure to vaping aerosols, PM2.5 and respiratory viruses may exert additive or synergistic effects on chronic airway inflammation. PM2.5 may amplify vaping-induced macrophage lipid accumulation, thereby reducing the macrophage clearance capacity. Decreased efferocytosis and autophagy may further exacerbate inflammation by increasing secondary necrosis from apoptotic cells and debris. This persistent inflammatory state coupled with epithelial injury and impaired antiviral responses may increase the risk of infection and accelerate the development or progression of chronic respiratory diseases such as asthma and COPD. These insights highlight the crucial need for polyexposure models to accurately reflect real-world environmental and behavioural exposures and evaluate their impact on respiratory health and disease exacerbations. Understanding this exposure triad is also crucial for refining exposure guidelines, updating risk assessments and implementing preventive strategies.",

Bletilla striata oligosaccharides (BSO) have immunomodulatory potential, yet their role in MAFLD via the gut-liver axis is unclear. This study aimed to investigate whether and how BSO ameliorates MAFLD by modulating gut microbiota, intestinal barrier function, and hepatic inflammation. MAFLD was induced in mice by 8-week high-fat diet followed by 12-week BSO (150, 300, 600 mg/kg) or metformin treatment via oral gavage. Compared with the MAFLD model, high-dose BSO reduced body weight gain, lowered fasting glucose, and decreased hepatic triglycerides. BSO also attenuated liver injury, hepatic steatosis, inflammation. Mechanistically, BSO restored gut barrier integrity, upregulated colonic tight junction proteins, activated colonic LXR\u03b1/ABCA1 signaling, while suppressing the hepatic TLR4/NF-\u03baB pathway. BSO remodeled gut microbiota, enriching beneficial Lachnospiraceae and Oscillospiraceae, and modulated hepatic metabolites, as shown by decreased confertifoline along with increased D-myo-inositol-4-phosphate. Additionally, BSO activated the intestinal FXR/FGF15 axis and ameliorated bile acid metabolism disorders, evidenced by reduced tauro-\u03c9-muricholic acid and cholic acid. This study provides systematic evidence that BSO alleviates MAFLD through a multi-target gut-liver axis mechanism involving gut microbiota remodeling, barrier restoration, activation of LXR\u03b1/ABCA1 and FXR/FGF15 signaling, and subsequent suppression of hepatic TLR4/NF-\u03baB-driven inflammation. Compared to previous approaches, BSO offers a favorable safety profile with combined regulatory effects. These findings support BSO as a promising candidate for MAFLD treatment, with potential applications as a dietary supplement or prebiotic agent.",

After obesity induction, 48 male Wistar rats were assigned to four 12-week interventions (n\u2009=\u200912/group): ND1 (140\u2009g/kg whey protein isolate), ND2 (ND1\u2009+\u2009L. acidophilus), HPD1 (500\u2009g/kg whey protein isolate) and HPD2 (HPD1\u2009+\u2009L. acidophilus). Supplemented groups received 5\u2009\u00d7\u2009108\u2009CFU/rat/day by oral gavage. Food intake, body-weight change, regional fat mass, serum biochemical markers and gut microbiota composition were evaluated. HPD-fed rats showed lower food intake, sustained body-weight loss and reduced visceral and epididymal fat masses compared with rats receiving normal-protein diets. Body-weight trajectories differed between dietary regimens (p\u2009=\u20090.013), whereas weight loss did not differ significantly between HPD1 and HPD2 (p\u2009=\u20090.06). Fasting glycemia remained unchanged. At month 3, ND1 showed the highest triglyceride and total cholesterol concentrations, while ND2, HPD1 and HPD2 displayed lower terminal values. High-protein feeding was associated with higher terminal urea and uric acid concentrations, whereas creatinine did not progressively increase. In the microbiota subset, HPD2 was characterized by higher relative abundances of Lactobacillus and Turicibacter. The whey protein-based HPD was the principal factor associated with body-weight reduction, lower adiposity and favorable lipid responses in obese rats. Under high-protein conditions, L. acidophilus did not confer an additional benefit for body weight or serum lipids, although its effect on gut microbiota composition warrants further functional investigation.",

Cassava peel is abundant but limited by high fiber and anti-nutritional factors. Fermentation using Pleurotus ostreatus can improve its nutritional quality and generate bioactive compounds. This study aimed to evaluate the effects of fermented cassava peel (FCP) on growth performance, carcass traits, immune response, intestinal morphology, microbial population, blood biochemical parameters, and fatty acid profile in broiler chickens. A total of broilers were randomly assigned to five dietary treatments: FCP0, FCP5, FCP10, FCP15, and FCP20, representing 0%, 5%, 10%, 15%, and 20% inclusion levels of FCP in the diet. The experiment was conducted over 35 days, including starter and finisher phases. Parameters measured included average daily weight gain (ADWG), average daily feed intake (ADFI), feed conversion ratio (FCR), live body weight (LBW), carcass characteristics, immune organ weights, intestinal villus height (VH), crypt depth (CD), VH/CD ratio, gut microbiota, blood lipid profile, and thigh meat fatty acid composition. Dietary inclusion of FCP significantly improved ADWG and LBW, particularly at the 20% level, without affecting ADFI and FCR. Carcass weight and percentage increased significantly (p < 0.05), while abdominal fat and physiological organs remained unaffected. Thymus weight and percentage were significantly increased, indicating enhanced immune response. Intestinal morphology showed increased VH and VH/CD ratio and decreased CD, reflecting improved absorptive capacity. Microbial analysis revealed reduced Escherichia coli and increased lactic acid bacteria populations. Blood analysis indicated reduced total cholesterol, triglycerides, and low-density lipoprotein, with increased high-density lipoprotein (p < 0.05). Although meat cholesterol was unchanged, FCP improved fatty acid composition by increasing omega-3, omega-6, omega-9, docosahexaenoic acid and eicosapentaenoic acid levels. FCP is an effective functional feed ingredient that enhances growth performance, gut health, immune status, and lipid metabolism in broiler chickens. Inclusion up to 20% can be recommended as a sustainable and economically viable strategy to improve poultry productivity and meat quality.",

Angiopoietin-like protein 3 (ANGPTL3) regulates lipid metabolism through inhibition of lipoprotein and endothelial lipases. Loss-of-function variants in ANGPTL3 are associated with lower plasma triglycerides, cholesterol, and reduced ASCVD risk. Zodasiran, a hepatocyte-targeted small interfering RNA (siRNA) against ANGPTL3, demonstrated significant lipid lowering in the Phase 2b ARCHES-2 trial. To evaluate the long-term safety and efficacy of zodasiran in adults with mixed hyperlipidaemia participating in the open-label extension (OLE) of ARCHES-2 (NCT04832971). Adults with mixed hyperlipidaemia (fasting triglycerides 1.7-5.6\u2005mmol/L and LDL-C\u2009\u2265\u20091.8\u2005mmol/L or non-HDL-C\u2009\u2265\u20092.59\u2005mmol/L) who completed 9 months of randomised treatment with placebo or zodasiran (50-, 100-, or 200-mg subcutaneously Q3\u2005M) were eligible for the OLE. The primary endpoint in the randomised doubleblind study was percent change in median triglycerides from baseline to Month 6. Here, lipid parameters were assessed through 21 months of the OLE; with total follow-up of 24 months. Of 191 participants completing randomised treatment, 156 (82%) enrolled in the OLE. Over 24 months, zodasiran was generally well tolerated; five participants (3.2%) discontinued due to adverse events; one (0.6%) death, not considered treatment-related, occurred. Injection site reactions were mild. By Month 21, median triglycerides were reduced by -55% (95% CI, 64, 43); remnant cholesterol by -57% (SD: 32); LDL-C by -5% (SD: 40); and ApoB by -13% (SD: 21). Zodasiran produced sustained reductions in triglycerides and atherogenic lipoproteins over 30 months and was well tolerated, supporting its potential as a long-term therapeutic option for mixed hyperlipidaemia. In this study, called the ARCHES-2 OLE study, we looked at the long-term safety and efficacy of zodasiran, an investigational medicine, in the treatment of mixed hyperlipidaemia.Mixed hyperlipidaemia is a disorder in which both triglycerides as well as LDL-cholesterol or non-HDL-cholesterol (\u201cbad\u201d cholesterol) are elevated.\u2022 Patients with mixed hyperlipidaemia have an increased risk for cardiovascular disease so it is important to diagnose and treat it as early as possible.\u2022 We had previously found that treatment with zodasiran could reduce triglycerides in these patients.In our current study, 156 adult patients with mixed hyperlipidaemia from that initial 9-month study were injected with zodasiran for an additional 2 years\u2022 The injection was given once every 3 months.\u2022 The treatment was well tolerated and reduced triglycerides as well as LDL-cholesterol and other disease-causing lipids.\u2022 These results are promising and we are now planning larger clinical studies to confirm these effects.",

Although plant lipids play essential biological roles and have considerable economic value, their conventional production from natural sources is often limited by sustainability, scalability and cost. Recent advances in synthetic biology enable the reprogramming of seed lipid metabolism for the tailored synthesis of valuable lipid compounds. In this review, we first summarize the core pathways of fatty acid biosynthesis and triacylglycerol assembly in seeds, together with the genetic transformation and genome editing toolkits available for major cereals. We then highlight recent progress in the heterologous production of specialized lipids, including eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), wax esters, and insect sex pheromones, in engineered plant systems. Finally, we discuss the potential of cereals as scalable and sustainable platforms for the production of high-value lipids. Together, these advances position engineered cereals as promising plant-based factories for applications in agriculture, nutrition, and the emerging bio-based economy.",

Emerging evidence suggests a link between systemic inflammation, lipid metabolism, and mental health. This study aims to evaluate whether first-trimester lipid profiles can predict postpartum depression (PPD) and anxiety in the post-pandemic context. A prospective cohort study of 266 pregnant women was conducted. Fasting lipids (Triglycerides, HDL, LDL) were measured at the 12th week of gestation. Mental health was assessed at 3 months postpartum using the Edinburgh Postnatal Depression Scale (EPDS) and Beck Anxiety Inventory (BAI). 22.6% of women exhibited PPD symptoms (EPDS >12). High first-trimester triglycerides (TG) and an elevated TG/HDL ratio (\u22651.9) were significantly associated with higher EPDS scores (p\u202f<\u202f0.001). Multivariable regression confirmed the TG/HDL ratio as an independent predictor of PPD (Adjusted OR 1.65; 95% CI 1.22-2.10). Early pregnancy lipid profiles show significant prospective associations with postpartum psychological distress, suggesting their potential role as early screening candidates that require further validation.",
"42498074": "ID: 42498074\nTitle: Defective m6A RNA Modification in Macrophages Exacerbates Inflammation and Promotes Colitis-Associated Carcinogenesis by Impairing Efferocytosis.\nAbstract: Chronic inflammation resulting from unresolved tissue injury is a potent driver of tumorigenesis. Macrophages are essential for efferocytosis, the clearance of apoptotic cells, which prevents secondary necrosis and promotes inflammation resolution. However, the epigenetic mechanisms regulating this process under inflammatory stress remain incompletely understood. Here, we identify the m6A methyltransferase METTL3 as a critical regulator of macrophage efferocytosis. Using various models of tissue injury, METTL3 expression was significantly downregulated in macrophages under inflammatory conditions and was associated with defective efferocytosis, the accumulation of apoptotic cells, and exacerbated chronic inflammation. Mechanistically, we reveal that METTL3-mediated m6A modification promotes IGF2BP2/3-dependent stabilization of MFGE8 mRNA, a process that is compromised upon METTL3 deficiency. In a colitis-associated cancer model, the efferocytosis defect associated with Mettl3 deficiency exacerbated chronic inflammatory tissue injury and increased susceptibility to colitis-associated cancer. Ultimately, external administration of recombinant MFGE8 protein effectively rescued the efferocytosis defect, mitigated inflammation, and reduced tumor burden in the AOM/DSS model. Collectively, our findings identify the METTL3-m6A-IGF2BP2/3-MFGE8 pathway as an important regulator of macrophage efferocytosis that may contribute to inflammation-associated carcinogenesis. These results suggest that targeting the METTL3-MFGE8 axis may represent a strategy for restoring efferocytosis and promoting inflammation resolution in chronic inflammatory diseases and inflammation-associated malignancies.",

Fifty-eight patients with type 2 diabetes were recruited and randomly divided into group SE egg (27 subjects) and ZE egg (31 subjects). The two groups of participants consumed either SE egg or ZE egg twice a day for a total of 12\u202fweeks of intervention. Fasting blood samples were collected before and after the intervention to detect changes in blood glucose and lipid levels. After the intervention, the fasting blood glucose, homeostatic model assessment of insulin resistance, and triglyceride-glucose index of both SE and ZE groups of subjects significantly decreased (p\u202f<\u202f0.05). Among subjects with a baseline glycosylated hemoglobin A1c (HbA1c)\u202f<\u202f8.9%, eggs from both groups showed an enhanced improvement in glucose and lipid metabolism. The ZE egg group showed a significant decrease in triglycerides (p\u202f=\u202f0.0007) and an increase in homeostatic model assessment of \u03b2-cell function (p\u202f=\u202f0.06).

"42501159": "ID: 42501159\nTitle: Docosahexaenoic Acid Protects Schwann Cells Against Palmitic Acid-Induced Lipotoxicity by Modulating Autophagy, ER Stress, and Lipid Handling.\nAbstract: Elevated saturated fatty acids, such as palmitic acid (PA), induce lipotoxicity in peripheral nerve cells, a pathological feature of metabolic disorders such as type 2 diabetes and obesity that are frequently associated with neuropathic pain (NP). PA overload elicits a maladaptive stress response characterized by endoplasmic reticulum (ER) stress, disrupted intracellular calcium homeostasis, and impaired autophagic flux, ultimately promoting cell death. Although omega-3 polyunsaturated fatty acids such as docosahexaenoic acid (DHA) protect against PA-induced lipotoxicity (PA-LTx), the mechanisms linking lipid handling, ER stress, and autophagy in Schwann cells remain poorly defined. Here, we investigated how PA and DHA regulate autophagic flux, ER stress signaling, and fatty acid-binding protein 5 (FABP5)-dependent lipid trafficking in immortalized Schwann cells (ISCs). PA exposure (300 \u00b5M PA:150 \u00b5M BSA, 24-48\u00a0h) significantly reduced cell viability, impaired autophagic flux as indicated by LC3-II and p62 accumulation, disrupted autophagosome-autolysosome balance, and increased susceptibility to autophagic inhibition by chloroquine. DHA co-treatment (50 \u00b5M) preserved cell viability, restored autophagic flux, and normalized autophagosome-autolysosome fusion. Mechanistically, PA induced ER stress marked by increased CHOP, ATF4, and Xbp1 expression, along with progressive ER calcium depletion, whereas DHA suppressed these responses and stabilized calcium homeostasis. Building on prior evidence that FABP5 protects neuron-like cells from PA-LTx, we identified a regulatory role for FABP5 in Schwann cells. PA robustly induced FABP5 expression, which was normalized by DHA and modulated by pharmacological manipulation of autophagy. FABP5 silencing exacerbated PA-induced ER stress, triggered a dysfunctional compensatory autophagy response, and impaired DHA-induced lipid droplet formation. Collectively, these findings demonstrate that functional autophagy and FABP5-dependent lipid buffering are critical adaptive responses to lipotoxic stress in Schwann cells, highlighting these pathways as potential therapeutic targets for NP-associated metabolic neuropathies.",

The aim of our study is to assess the features of metabolic phenotypes and proinflammatory status in young normal weight and overweight adults without significant somatic pathology in 2 groups: up to 35 years and \u226535 years. A cross-sectional study included 159 individuals aged 18 to 45 years with normal and overweight body mass. In addition to standard clinical and laboratory examinations, indices reflecting metabolic disorders and pro-inflammatory status were calculated for all patients. A glucose tolerance test was performed on 61 patients, and the area under the curve (AUC) of plasma glucose levels was assessed. In the subgroup of patients aged 35 years and older, abdominal obesity was twice as common compared to patients younger than 35 years (p<0,001) at comparable body mass index. Patients in the older age group were characterized by higher fasting blood glucose levels (p=0,042), glucose levels 1 hour (p=0,011) and 2 hours (p=0,020) after a standard carbohydrate load, as well as a higher prevalence of dyslipidemia (p=0,001), while no significant differences in pro-inflammatory status were identified. Using a decision tree, the characteristics of metabolic phenotypes in the two age subgroups were determined, taking into account the presence of abdominal obesity and plasma glucose AUC characteristics. Thus, in patients aged 35 years and older, subclinical disorders of carbohydrate and lipid metabolism, as well as abdominal obesity, play a significant role in the development of a metabolically \u00abunhealthy\u00bb phenotype. This phenotype is associated with an increased risk of cardiovascular events and indicates early subclinical aging. \u041e\u0441\u043e\u0431\u0435\u043d\u043d\u043e\u0441\u0442\u0438

"42504493": "ID: 42504493\nTitle: Genetic Determinants of Interindividual Differences in Provitamin A Carotenoid Concentrations in Human Adipose Tissue.\nAbstract: Adipose tissue is a major storage site for provitamin A carotenoids (proVA CAR)-mainly \u03b2-carotene (BCAR), \u03b1-carotene (ACAR), and \u03b2-cryptoxanthin (BCRY). However, the determinants of their concentrations in this tissue remain poorly understood. This study aimed to identify genetic variants associated with adipose tissue proVA CAR concentrations. Periumbilical adipose tissue samples were collected on six occasions in 43 healthy adult males and proVA CAR concentrations were quantified by HPLC. Participants were genotyped for 2,398 SNPs in 44 candidate genes involved in CAR and lipid metabolism, and genetic associations were assessed using partial least squares (PLS) regression. Adipose tissue proVA CAR concentrations ranked as BCAR > ACAR > BCRY, with CV ranging from 54 to 66%. PLS regression models integrating fasting plasma proVA CAR concentrations and SNPs explained 69, 59, and 67% of the variability in BCAR, ACAR, and BCRY concentrations, respectively. In a multivariate PLS regression model, the main determinants of proVA CAR concentrations were fasting plasma BCAR and ACAR concentrations and four SNPs-rs4694627 (CXCL8), rs7558381 (IRS1), rs709157 and rs1152004 (PPARG). Interindividual variability in adipose tissue proVA CAR concentrations is partly explained by genetic variation in genes involved in CAR and lipid metabolism.

These disturbances underscore the need for safe interventions capable of restoring metabolic regulation. Senna alexandrina (SA), traditionally used for weight reduction, has recently been shown to modulate the gut microbiota beyond its laxative effects. To enhance efficacy while minimizing adverse outcomes, this study investigated the effects of a low and safe dose of SA combined with intermittent fasting (IF), a strategy that reshapes nutrient availability and microbial dynamics. HFSD\u2011induced obese rats were treated for four weeks with SA leaf powder (300\u00a0mg/kg/day), IF, or both. Bioactive constituents of SA were characterized using LC\u2011HRMS, alongside systematic evaluation of physiological and metabolic parameters-including adiposity, morphometry, lipid profiles, insulin sensitivity markers, and gut-endocrine axis indicators. SA supplementation showed improvements across all parameters, surpassing those achieved with IF alone. Importantly, the combined intervention (SA+IF) yielded complementary benefits, notably enhancing GLUT4 expression, short\u2011chain fatty acid (SCFA) production, peptide YY (PYY) secretion, and reducing the Firmicutes/Bacteroidetes ratio. These findings highlight the complementary roles of SA and IF in metabolic regulation, providing experimental evidence for a potential dietary approach to mitigate obesity\u2011related dysfunction.",

A long-term high-fat diet (HFD) can lead to obesity and other metabolic disorders, which significantly contribute to stone formation. Recent studies indicate that time-restricted feeding (TRF) plays a crucial role in improving metabolic homeostasis and preventing metabolic diseases. However, its impact on kidney stone formation has yet to be investigated. We examined differences in calcium oxalate crystal formation in mouse kidneys using glyoxylic acid (Gly) modeling in HFD mouse models subjected to either ad\u00a0libitum (Ad) feeding or TRF. TRF mitigated weight gain, improved blood lipid metabolism disorders, and reduced lipid deposition in the liver and kidneys, alleviating pathological damage. Compared with the Ad group, the TRF group exhibited lower urinary concentrations of oxalate and calcium ions, which corresponded with reduced expression of OPN and CD44, leading to decreased oxalate crystal formation. Gly intervention in the Ad group increased the expression of TNF-\u03b1 and IL-6 in the kidneys, leading to an imbalance between oxidative stress and antioxidant responses. In contrast, TRF showed significant improvement, potentially linked to activation of the PI3K-AKT pathway. Nighttime TRF, which more closely aligns with the natural work and rest rhythms of mice, produced more pronounced effects than daytime TRF. NR1D1 expression in the kidneys was closely associated with stone formation. TRF can improve lipid metabolism and inhibit the formation of renal calcium oxalate stones, and dietary preventive strategies that align with biological rhythms demonstrate particularly significant effects.",

Natural polyphenols such as curcumin and resveratrol, alongside mesenchymal stem cell (MSC) secretome, have demonstrated complementary anti-inflammatory, antioxidant, and pro-angiogenic properties with potential for wound healing. This study reports two complementary in vitro investigations evaluating the release profiles of curcumin and resveratrol from two polymeric platforms: poly(vinyl alcohol)/sodium alginate/carboxymethylcellulose films (Study 1) and an acrylate copolymer-based hydrogel incorporating MSC secretome (Study 2). UV-Vis spectrophotometric analysis confirmed analytical selectivity with no interference from excipients. Resveratrol exhibited progressive and consistent release from the hydrogel. Curcumin compromised polymer matrix integrity and reduced resveratrol release efficiency. Also showed unsatisfactory release in both systems, attributed to its low aqueous solubility. These results support the use of resveratrol-loaded polymeric matrices as promising sustained-release platforms for bioactive wound dressings and highlight the need for nanoencapsulation strategies to improve curcumin bioavailability.",

However, the intergenerational impacts of parental DZP exposure on fish offspring remain poorly understood. In this study, we exposed zebrafish (F0) to DZP at 8 \u03bcg/L for 7 days and investigated variation in the development, behavior, and transcriptional profiles of their offspring (F1) reared in DZP-free medium. The results suggest that DZP accumulates in F0 ovaries and is vertically transmitted to F1 embryos, resulting in-ovo exposure. The parental DZP exposure significantly increased F1 embryo mortality and accelerated their hatching. Moreover, parentally DZP-exposed F1 larvae exhibited reduced locomotor activity and increased exploratory behavior. Transcriptomic analysis identified 404 differentially expressed genes, which were significantly enriched in KEGG pathways related to metabolism and organismal systems. In parentally DZP-exposed F1 larvae, transcriptional responses in the pathways of xenobiotic biodegradation and metabolism were driven primarily by key genes encoding detoxification enzymes, and the activation of lipid metabolism pathways was underpinned by the up-regulated expression of vital apolipoprotein-encoding genes. Conversely, circadian rhythm suppression was characterized by coordinated downregulation of clock and cryptochrome genes. Overall, these findings provide preliminary insights into the intergenerational toxicity induced by parental DZP exposure, offering potential molecular clues for future studies on its ecotoxicological effects on the fish population.",
"42510742": "ID: 42510742\nTitle: The Biological Clock-Mitochondria Axis in the Liver: From Molecular Mechanisms to Metabolic Disease.\nAbstract: The liver ranks among the peripheral organs exhibiting the most robust circadian rhythmicity, with glucose homeostasis, lipid metabolism, and bile acid turnover governed by tightly phased diurnal oscillations. Mitochondria execute these programs, their output coordinated with the hepatocyte circadian state. The mitochondrial network undergoes dynamic remodeling across the 24 h cycle, encompassing oscillatory changes in bioenergetics, fusion-fission balance, and quality control. This interplay is bidirectional: core clock components drive rhythmic remodeling via cyclin-dependent kinase 1/mitogen-activated protein kinase (CDK1/MAPK)-dependent phosphorylation of dynamin-related protein 1 (DRP1) and the NAD+-SIRT1/SIRT3 axis, while retrograde signals modulate clock amplitude and entrainment. Circadian disruption is associated with mitochondrial dysfunction implicated in MASLD onset and progression to MASH and HCC, though this evidence remains largely correlative and derives predominantly from rodent models. This review integrates clock-mitochondria coupling with metabolic liver disease. Restoring this coupling has been proposed as a candidate chronotherapeutic strategy, supported by preliminary rhythmicity data in primary human hepatocytes and a hepatocellular carcinoma cell line, though causal validation in healthy human liver is lacking. Time-restricted feeding, NAD+ precursors, PPAR agonists, and ACC inhibitors converge on clock-regulated pathways and may benefit from circadian-informed timing, though this remains unverified.",

However, DHA enrichment in ruminant milk is limited by inefficient post-absorptive transport. This study evaluated whether combined supplementation of rumen-protected algae powder (RPA) and rumen-protected choline (RPC) enhances DHA enrichment in goat milk. Nine lactating dairy goats were assigned to three groups (n = 3/group) for 28 days: RPA alone, RPA + low-dose RPC (5 g/d), and RPA + high-dose RPC (10 g/d). Milk DHA content, bioconversion efficiency, serum biochemical parameters, and lipid profiles were analyzed. Compared with RPA alone, low- and high-dose RPC increased milk DHA content to 27.98 and 33.50 mg/100 mL, respectively, representing increases of 23.0% and 47.3%, and enhanced DHA bioconversion efficiency to 20.66% and 24.29% compared with 16.86% in the RPA group. RPC supplementation increased serum VLDL and triglyceride concentrations, and lipidomics revealed increased DHA-containing triglycerides (TG-DHA). These findings suggest that RPC may enhance DHA enrichment in goat milk by promoting VLDL-mediated DHA transport. Further studies with larger animal populations are required to confirm these effects. These findings contribute to a better understanding of nutritional regulation of DHA transfer and provide insights into strategies for developing DHA-enriched dairy products.",
"42511870": "ID: 42511870\nTitle: Rosmarinic Acid Ameliorates Obesity-Associated Metabolic Disturbances and Hepatic Steatosis in Mice with High-Fat Diet-Induced Obesity.\nAbstract: Obesity and obesity-associated hepatic steatosis represent major metabolic health challenges, yet effective pharmacological interventions remain limited. Rosmarinic acid (RA), a natural polyphenol, has been reported to exert anti-obesity effects; however, its specific roles in restoring hepatic lipid homeostasis and modulating glucose metabolism under diet-induced obesity remain unclear. In this study, we investigated the metabolic effects and underlying mechanisms of RA in mice with high-fat diet (HFD)-induced obesity. RA significantly reduced body weight gain and adipose tissue mass without altering total energy intake, accompanied by increased nocturnal energy expenditure and fecal lipid excretion. RA restored hepatic lipid homeostasis by improving circulating lipid profiles and markedly attenuating hepatic steatosis, fibrosis, and hepatocellular injury. These effects were associated with increased fecal lipid excretion, suppression of hepatic lipogenesis, and enhancement of fatty acid oxidation-related markers. Furthermore, RA reduced fasting blood glucose levels and modulated the expression of hepatic glucose metabolism-related genes. Pancreatic immunohistochemistry showed morphological changes in insulin-positive and glucagon-positive cells following RA supplementation. Collectively, these findings indicate that RA ameliorates obesity-associated metabolic disturbances and hepatic steatosis through coordinated regulation of lipid metabolism and hepatic glucose metabolism-related pathways, highlighting its potential relevance for obesity-associated fatty liver conditions.",

(Theaceae) seed oil is an essential component for skin protection, attributed to its antioxidant properties and anti-aging effects. In this study, Camellia japonica seed oil underwent fermentation with Sporidiobolus pararoseus (Fell & Tallman, CGMCC No. 39106, commercial name: Longevity yeast of 1021-year-Camellia japonica). The post-fermented oil, designated Longevity Yeast Oil (LYO), was used in the present research. Gas chromatography-mass spectrometry analysis demonstrated that methyl esterification of LYO afforded twelve fatty acid methyl esters. We used an aging model in human epidermal keratinocytes and human skin fibroblasts exposed to ultraviolet B (UVB) to explore the anti-skin aging effects and mechanisms of LYO. The results of the CCK-8 assay demonstrated that LYO exhibited no cytotoxicity but instead displayed potential proliferative activity, indicating its excellent safety profile. Quantitative real-time polymerase chain reaction analyses confirmed that LYO downregulated the expression of autophagy marker p62 and upregulated LC3B, thereby activating the autophagic pathway. Further investigation revealed that LYO protected against UVB-induced apoptosis, promoted the synthesis of collagen and elastin, and upregulated the expression of loricrin, filaggrin, and ceramides, effectively reversing UVB-induced skin cellular aging. Notably, we further revealed that LYO alleviated UVB-induced cutaneous photoaging via activating cellular autophagy pathway. In conclusion, LYO demonstrated biocompatibility and conferred protection to skin cells against photoaging, thereby establishing a theoretical basis for the development of innovative autophagy-targeted anti-aging therapies.",
"42514304": "ID: 42514304\nTitle: Olive Oil as a Modulator of Gut Microbiota and Intestinal Health: A Narrative Review from Microbial Metabolism to Host Responses.\nAbstract: Olive oil, particularly virgin (VOO) and extra-virgin olive oil (EVOO), is a central component of the Mediterranean diet and has been associated with cardiometabolic, anti-inflammatory, and intestinal health benefits. Increasing evidence suggests that these effects may involve interactions with the gut microbiota, intestinal barrier, and host inflammatory pathways. This narrative review summarizes current evidence on the impact of olive oil, olive-derived phenolics, and olive oil-rich dietary patterns on gut microbiota modulation, barrier function, inflammatory bowel diseases, and related systemic outcomes. The available literature indicates that olive oil may interact with the gut ecosystem through both its oleic acid-rich lipid matrix and its minor phenolic fraction. VOO and EVOO appear more consistently associated than refined oils with microbial or microbial metabolite profiles related to saccharolytic metabolism, short-chain fatty acid production, mucus-layer dynamics, and anti-inflammatory intestinal environments. Olive-derived phenolics, including hydroxytyrosol, tyrosol, oleuropein derivatives, and oleocanthal, can undergo microbial biotransformation and may influence bile acid metabolism, epithelial barrier integrity, and inflammatory signaling. Whole EVOO evidence is strongest in experimental colitis models, whereas human evidence mainly supports effects on postprandial endotoxemia, lipid oxidation, and selected inflammatory markers. However, findings remain heterogeneous and depend on oil quality, phenolic composition, comparator fat, dietary context, and host condition. Well-controlled human studies directly comparing EVOO, VOO, refined olive oil, and oleic acid-rich controls are needed to clarify reproducible microbiota-mediated effects and their relevance to intestinal and systemic health.",
"42520678": "ID: 42520678\nTitle: Dual role of macrophage heterogeneity in allergic inflammation: from mechanism to targeted therapy.\nAbstract: Allergic inflammation, such as allergic asthma, allergic rhinitis, and atopic dermatitis, shares many pathogenic hallmarks, including inappropriate activation of type 2 immune responses, tissue barrier dysfunction, and disruption of local homeostasis. Due to their remarkable plasticity and tissue adaptability, macrophages are crucial effector cells of the innate immune system that play complex, context-dependent dual roles in allergic inflammation. On the one hand, macrophages are implicated in the persistence of chronic inflammation, thereby boosting Th2 cell recruitment, eosinophil infiltration, antigen processing, chemokine secretion, inflammatory mediator release, and tissue remodeling. On the other hand, they promote the resolution of inflammation by triggering barrier repair, producing anti-inflammatory mediators including TGF-\u03b2 and IL-10, and phagocytosing apoptotic cells. Recent single-cell transcriptomic and functional studies have demonstrated that macrophages are dynamically distributed along an activation continuum rather than merely fitting into the traditional M1/M2 polarization. Functional states are determined by cellular origin, illness stage, tissue niche, and complex regulatory networks. For macrophages implicated in airway inflammation and remodeling, non-IgE-dependent nasal neurogenic reflexes, skin barrier disruption, itch neuroimmune circuits, and inflammation resolution, distinct barrier tissues-such as the lung, nasal mucosa, and skin-show notable tissue specificity. The pathogenic and preventive functions of macrophages in allergic inflammation are systematically summarized in this review, which also emphasizes a continuous spectrum of macrophage activation and incorporates interactions among metabolic reprogramming, pyroptosis, epigenetic control, and trained immunity. Given the dynamic and microenvironment-dependent nature of macrophage function, future treatment approaches need to shift from broad anti-inflammatory therapies to precision reprogramming that is stage-specific and tissue-tuned. During the start and amplification stages of inflammation, therapeutic strategies should target pathogenic M2a-like programs, chemokine networks, monocyte recruitment, and excessive pyroptotic responses. On the other hand, M2b/M2c and pro-resolving macrophage-mediated efferocytosis, immunological tolerance, and tissue healing should be the focus of tactics in the resolution and repair stages. Furthermore, the management of allergic diseases may shift from empirical anti-inflammatory therapy to mechanism-guided precision interventions through patient stratification based on single-cell omics, spatial omics, and macrophage-associated biomarkers.",
"42521405": "ID: 42521405\nTitle: Impact of Grape Seed Extract on Flavor and Functionality of Pea Protein Extrudates and Patties.\nAbstract: Consumer interest in plant-based proteins is increasing, but undesirable off-flavors from Maillard reaction and lipid oxidation processes hinder their broader acceptance. Our previous work showed that proanthocyanidin-rich plant extracts like grape seed extract (GSE) could reduce the formation of these off-flavors in aqueous plant protein solutions. This study investigated the effects of GSE addition pre- and post-extrusion at two levels (0.02% and 1.0% w/w) on off-flavor development in pea protein extrudates and patties. We hypothesized that GSE addition at different processing phases would impact its ability to alter Maillard reaction and lipid oxidation processes, thus affecting its ability to mitigate off-flavor formation. Pre-extrusion treatments reduced Maillard-associated browning products by 40% more than post-extrusion treatments, potentially due to greater protein-polyphenol interactions during extrusion-induced protein denaturation and restructuring. Conversely, post-extrusion GSE treatment decreased primary and secondary lipid oxidation products by approximately 53% and 44% in patties, respectively (vs. 15% and 31%, respectively, in pretreated samples), and enhanced antioxidant capacities across all samples. Because post-extrusion GSE treatments exhibited fewer apparent protein-polyphenol interactions, a larger proportion of polyphenols may have remained chemically available for radical scavenging. Sensory evaluation suggests that GSE did not impart astringency, a common concern with polyphenol addition. These results indicate that polyphenols may be a promising strategy for improving flavor quality in plant-based protein products. PRACTICAL APPLICATIONS: Addition of grape seed extract can help reduce off-flavors in legumes caused by major flavor degradation pathways. Adding polyphenols before processing can reduce Maillard-derived off-flavors, while polyphenols added after processing are more effective at reducing lipid oxidation-derived off-flavors. This approach offers a simple and sustainable way to enhance flavor quality and properties of plant-based meat alternatives.",
"42522304": "ID: 42522304\nTitle: Nutritional Adjuvants in Diabetes: Biotin and Chromium Picolinate as Emerging Therapeutic Agents.\nAbstract: Insulin resistance and type 2 diabetes mellitus (T2DM) are serious worldwide health issues linked to dyslipidaemia, oxidative stress, impaired glucose metabolism, and persistent inflammation. Although their clinical significance is still unknown, micronutrients like chromium and biotin are thought to affect insulin signalling, glucose homeostasis, and lipid metabolism. The purpose of this review is to compile the preclinical, clinical, and epidemiological data that is currently available regarding the individual and combined effects of chromium and biotin on metabolic outcomes, insulin sensitivity, and glycaemic control. Using databases like PubMed, Scopus, and Google Scholar, a thorough search of narrative literature was carried out. Included were pertinent experimental, clinical, and review studies evaluating the use of chromium and/or biotin supplements in diseases like metabolic syndrome, insulin resistance, and type 2 diabetes. With a focus on study design, dosage, duration, mechanistic pathways, and reported metabolic outcomes, the evidence was qualitatively examined. Preclinical research repeatedly shows that biotin and chromium improve oxidative stress markers, lipid profiles, insulin sensitivity, and glucose tolerance. Increased GLUT-4 translocation, AMPK activation, insulin signalling pathway modulation (IRS-1/PI3K/Akt), and biotin-dependent enzyme regulation are some of the mechanisms that mediate these effects. Particularly in those with poor glycaemic control or micronutrient deficiencies, clinical trials show modest but significant improvements in fasting blood glucose, HbA1c levels, insulin resistance indices, and lipid parameters. Glycaemic control, dyslipidaemia, oxidative stress, and cardiovascular risk markers all seem to improve with combined supplementation. Additionally, epidemiological data point to a negative correlation between dietary chromium consumption and the risk of T2DM. The results demonstrate the complementary functions of biotin and chromium in controlling the metabolism of fats and carbohydrates. When taken together, they may provide greater metabolic advantages than when taken separately. However, the generalisability of findings is constrained by variations in study design, participant characteristics, supplement formulations, and baseline nutritional status. The necessity of standardized research methods is highlighted by these discrepancies. In general, chromium and biotin exhibit promise as supplemental treatments for the treatment of insulin resistance and type 2 diabetes, especially in populations with nutritional deficiencies or metabolic disorders. However, more extensive, carefully planned randomized controlled trials are needed to ascertain the best dosage, long-term safety, and clinical effectiveness.",

Given the growing interest in non-pharmacological strategies to complement or support tapering of GLP-1 receptor agonist therapy, a structured overview of the human evidence is needed. A pre-registered scoping review was conducted using PubMed, Scopus and Cochrane Central. Randomized controlled trials in adults assessing circulating GLP-1 concentrations and satiety following supplementation with a single, well-defined dietary fiber were included. Fiber types were categorized based on structural characteristics. Outcomes were summarized qualitatively across fiber categories. In total, 1049 papers were screened and 49 publications comprising 52 studies (total n=1,085 participants; median sample size per study=19) were included. Most studies were acute interventions (71%) and conducted in Western populations. Studies reporting increased GLP-1 showed a non-significant tendency to also report increased satiety (OR\u00a0=\u00a02.95, 95% CI: 0.87-9.98). Dextrins stood out as one of the few fiber categories showing robust effects on both GLP-1 (4 positive studies) and satiety (5 positive studies). Other fibers, such as \u03b2-glucans and mannans, showed more uniform effects on satiety or GLP-1, respectively, but did not consistently affect both outcomes simultaneously. Although these findings identify dextrins as a promising dietary fiber candidate for future research, the evidence remains constrained by small sample sizes, short interventions, and substantial heterogeneity. Longer-term studies in free-living conditions, including periods of GLP-1 receptor agonist tapering, are needed to capture microbiota adaptation and generate robust real-world evidence. https://osf.io/cnw4e/overview.",

This PRISMA 2020-based systematic review searched PubMed, Cochrane Library, Web of Science, Embase, China National Knowledge Infrastructure (CNKI), and VIP Database (VIP) from inception to March 10, 2026. Restricted maximum likelihood (REML) random-effects models pooled mean differences (MDs) with 95% confidence intervals (CIs), and heterogeneity was assessed using Cochran's Q and I2. Subgroup, meta-regression, sensitivity, publication bias, RoB 2.0, and GRADE analyses were conducted. A total of 20 randomized controlled trials (RCTs) involving 745 college students were included, with 377 in HIIT and 368 in MICT. Compared with MICT, HIIT significantly reduced body weight (MD = -1.23\u00a0kg, 95% CI -1.94 to -0.52, P\u00a0=\u00a00.002), body fat percentage (MD = -1.21%, 95% CI -2.12 to -0.30, P\u00a0=\u00a00.013), waist-to-hip ratio (MD = -0.01, 95% CI -0.02 to -0.00, P\u00a0=\u00a00.014), waist circumference (MD = -1.33\u00a0cm, 95% CI -2.40 to -0.26, P\u00a0=\u00a00.023), and fat mass (MD = -0.99\u00a0kg, 95% CI -1.66 to -0.33, P\u00a0=\u00a00.010). No significant differences were found for body mass index (BMI), hip circumference, muscle mass, total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), fasting blood glucose (FBG), or fasting insulin (FINS). Subgroup analyses suggested sex might influence body weight and BMI effects, but most analyses showed no clear moderation. Meta-regression detected no significant moderation by duration or weekly HIIT volume. Evidence for body composition outcomes was mostly moderate, low, or very low; evidence for glucose and lipid metabolism outcomes was very low. Compared with MICT, HIIT may provide greater benefits for selected body composition measures in college students, particularly body weight, body fat percentage, waist circumference, waist-to-hip ratio, and fat mass. However, HIIT did not consistently improve routine glucose and lipid metabolism markers.

Although endurance training (ETR) is known to improve metabolic health, it remains unclear whether exercise timing and training duration influences metabolic adaptations under CR disruption. Twenty-four male Sprague-Dawley rats were randomly assigned to four groups: regular sleep cycle sedentary (RSC), irregular sleep cycle sedentary (ISC), irregular sleep cycle with late-stage ETR (ISE), and irregular sleep cycle with prolonged ETR (IEE). CR disruption was induced by alternating light-dark cycles every three days for 20 weeks. ETR was performed at moderate intensity. Skeletal muscle and liver samples were analyzed for circadian clock proteins, mitochondrial biogenesis, glucose and lipid metabolism, oxidative stress, and fibrosis-related markers. CR disruption significantly impaired circadian clock regulation, mitochondrial biogenesis, and metabolic function in both skeletal muscle and liver. Specifically, reductions in BMAL-1 expression, AMPK activation, PGC-1\u03b1 signaling, and oxidative phosphorylation were observed, along with disrupted glucose and lipid metabolism. These alterations were accompanied by increased oxidative stress, hepatic lipid accumulation, and fibrosis-related markers. ETR effectively attenuated these changes. Notably, training initiated prior to CR disruption (or a higher fitness maintained during CR disruption) group (IEE) resulted in greater improvements in mitochondrial and metabolic adaptations compared with shorter-duration training (ISE). In contrast, no significant differences were observed between ISE and IEE in oxidative stress and fibrosis-related outcomes. Endurance training mitigates CR disruption-induced metabolic dysfunction in skeletal muscle and liver. Prolonged training exposure enhances mitochondrial and metabolic adaptations, whereas protective effects on oxidative stress and fibrosis may occur even with shorter training duration. These findings highlight the importance of exercise timing and training duration in optimizing metabolic resilience under circadian disruption.",

There is increasing evidence that diet, gut microbiota, microbial metabolites and chronic inflammation are important factors in colorectal carcinogenesis and may provide novel opportunities for prevention, diagnosis and treatment. To provide a comprehensive review of the current evidence on the role of diet, nutrition, microbial metabolism and chronic inflammation in CRC, with emphasis on emerging translational applications including microbiome-based biomarkers and microbiota-targeted therapeutic strategies. A literature search was performed with PubMed, Scopus and the Cochrane Library. Relevant studies on diet-microbiota interactions, microbial metabolites, inflammatory mechanisms, colorectal carcinogenesis, microbiome-derived biomarkers, and microbiota-targeted interventions were identified and reviewed. Preclinical and clinical studies and high quality reviews and meta-analyses were considered. Dietary patterns have been shown to have a major impact on the composition and function of the gut microbiota. Rich-fiber diets and short-chain fatty acids (SCFAs) production seem protective against CRC, while western dietary patterns, ultra-processed foods and dysbiosis-associated metabolites promote a pro-inflammatory environment associated with carcinogenesis. Some microorganisms such as Fusobacterium nucleatum, enterotoxigenic Bacteroides fragilis and pks-positive Escherichia coli have been associated with CRC by inflammatory, genotoxic and immune-modulatory mechanisms. Recent advances in sequencing technologies and multi-omics approaches have enabled the identification of microbial signatures with potential diagnostic and prognostic value. Moreover, microbiota-targeted interventions such as probiotics, prebiotics, postbiotics, faecal microbiota transplantation, and next-generation microbial therapies have yielded promising preclinical and early clinical results. The diet-microbiota-inflammation axis is a key player in colorectal carcinogenesis and a promising target for translational research. Microbiome-based biomarkers and microbiota-targeted therapies may have a role in future precision prevention and personalised management strategies of colorectal cancer despite significant challenges in terms of causation, standardisation and translation into clinical practice.",

Comparative studies on long-term trends of its three core components [ischemic heart disease (IHD), diabetic kidney disease (DKD), non-alcoholic fatty liver disease (NAFLD)] across major countries are still limited. We analyzed age-standardized disability-adjusted life year (DALY) rates of IHD, DKD, and NAFLD attributable to high fasting plasma glucose (HFPG) from 1990 to 2021 among seven representative middle-and high-income countries using Global Burden of Disease 2021 data. We assessed temporal trends, conducted hierarchical clustering, and projected burdens to 2050. We found substantial cross-country heterogeneity. From 1990 to 2021, IHD burden decreased significantly in the United States and Japan, while trends in China and India showed high uncertainty (coefficients of variation >100%) and should be interpreted with caution. DKD burden increased in Saudi Arabia and the United States but decreased in China. NAFLD burden increased in Saudi Arabia, the United States, India, and South Africa, while declining in China and Japan. Cluster analysis identified three patterns: \"High IHD Burden\" (India), \"High Metabolic Burden\" (Saudi Arabia), and \"Low-Moderate Burden\" (other countries). HFPG was associated with the largest share of DKD burden (Population Attributable Fraction [PAF] >80%) and a substantially smaller share of NAFLD burden (PAF <11%).Projections to 2050 show a sharp rise in DKD in the United States and India, together with increasing NAFLD burden, indicating a shift toward metabolic organ damage. The burden of CKM syndrome is substantial and dynamic, with marked cross-country differences.

Preclinical evidence consistently showed that these polyphenols inhibit nuclear factor kappa B (NF-\u03baB), phosphoinositide 3-kinase/protein kinase B/mechanistic target of rapamycin (PI3K/Akt/mTOR), signal transducer and activator of transcription 3 (STAT3), and Wnt/\u03b2-catenin signaling, while promoting apoptosis, antioxidant responses, and suppression of inflammation, proliferation, angiogenesis, and metastasis. These effects were associated with reduced tumor burden in animal models. Epidemiological studies suggested modest protective associations, particularly for green tea consumption, but findings were inconsistent, frequently confounded, and of limited generalizability. Human trials predominantly demonstrated biomarker modulation, whereas effects on adenoma recurrence were mixed and no consistent benefits were observed for tumor regression, recurrence, progression-free survival, or overall survival. Clinical translation is further limited by poor absorption, rapid metabolism, uncertain activity of metabolites, formulation variability, and potential hepatotoxicity and drug interactions, although high local colorectal exposure may remain biologically relevant. Curcumin, resveratrol, and EGCG therefore show strong mechanistic potential but cannot currently be recommended as stand-alone CRC therapies. They should be regarded as investigational preventive or adjunctive agents pending adequately powered randomized trials using standardized formulations, optimized dosing, and clinically meaningful endpoints.",

Amplification of thioredoxin reductase (TrxR) and activation of the Keap1-Nrf2-FOXO3 pathway may contribute to enhanced drug efflux, strengthens antioxidant defenses, and resistance to oxidative stress-induced apoptosis in certain tumors. Redox-based drug repurposing offers a promising strategy to overcome MDR by targeting these shortcomings. Repurposing drugs including metformin, auranofin, brusatol, and natural polyphenols increase reactive oxygen species (ROS) and make MDR cells more sensitive to chemotherapy via modulation and inhibiting Nrf2 or TrxR. Nanotechnology advancements and combination of repurposed drugs with anticancer drugs, ferroptosis inducers may improve tumor selectivity while lowering systemic toxicity. Preclinical experiments show effectiveness by suppressing antioxidant pathways, inhibiting efflux pump function, and delivering drugs in a redox-responsive manner. Next-generation tumor-selective delivery systems, adaptive clinical trial designs, and biomarker-driven patient classification based on TrxR expression or Keap1/Nrf2 mutations are the main areas of focus. Translation into clinical practice could be accelerated by combining specific redox profiling, nanocarrier technologies, and pharmacokinetics. For MDR cancer, redox-targeted drug repurposing is an effective, precision-based strategy for recovering chemosensitivity and enhancing treatment outcomes.",

In this process, the narrow junctional gap between the membrane of the transverse tubules (TT), which conduct the surface action potential into the fiber volume, and the membrane of the terminal cisternae of the SR has to be bridged. The publication by Rios and Pizarro in this journal issue (https://doi.org/10.1085/jgp.202613968) offers a model inspired by structural data that comprehensively explains many aspects of the coupling process.",

To date, most PP investigations have focused on mono- or dual-omics analyses; however, integrating multiple omics layers is crucial to fully elucidate their biological and mechanistic effects. This review outlines current omics strategies and their integration in PP research, emphasizing how these approaches can help improving our understanding and lead to more efficient applications. Furthermore, we report the growing importance of integrative multi-omics approaches in nutritional research, with particular regard to the inter-individual variability in PP metabolism. Finally, we discuss the pivotal role of these approaches in precision nutrition, providing insights on how integrative multi-omics approaches may enhance tailored nutritional interventions and unlock new possibilities to foster human health.",

Concurrently, the induction of apoptosis and ferroptosis is a promising therapeutic strategy. This study aimed to investigate whether the natural product, verbascoside, induces apoptosis and ferroptosis in NSCLC cells by targeting BCAT2. Bioinformatic analysis was used to predict the potential targets of verbascosides. Stable cell lines with BCAT2 knockdown and overexpression were constructed. The effects of verbascoside on NSCLC were evaluated in vitro and using a mouse xenograft model. Bioinformatics screening and molecular docking identified BCAT2 as a potential target of verbascoside, with a significantly stronger binding energy (-7.8 kcal/mol) than another candidate, PARP1. In vitro and in vivo experiments confirmed that BCAT2 knockdown significantly inhibited NSCLC cell viability, induced apoptosis and ferroptosis, and induced mitochondrial damage. Conversely, BCAT2 overexpression produced opposite effects. Verbascoside treatment inhibited BCAT2 expression in a concentration-dependent manner, recapitulating the apoptotic, ferroptotic, and mitochondrial damage phenotypes induced by BCAT2 knockdown; however, BCAT2 overexpression significantly reversed these effects of verbascoside. In an animal model, treatment with verbascoside significantly suppressed tumor growth and activated apoptosis and ferroptosis in tumor tissues by downregulating BCAT2. Verbascoside can induce apoptosis and ferroptosis in NSCLC by directly targeting and inhibiting BCAT2, leading to mitochondrial dysfunction. This finding not only reveals BCAT2 as a novel target of verbascoside but also confirms its ability to induce apoptosis and ferroptosis in NSCLC cells.",

This study investigated how bile salt hydrolase (BSH)-active probiotics alleviate sarcopenia through bile acid deconjugation and remodeling, activating the intestinal FXR-FGF15/19 signaling pathway, and explored their application in functional dairy products. Three high-BSH strains-Lactiplantibacillus plantarum H-87, Bifidobacterium animalis F1-7, and F1-3-2-were identified, among which F1-7 and F1-3-2 showed superior efficacy in a dexamethasone-induced sarcopenia model. These strains improved muscle mass, morphology (including increased muscle fiber cross-sectional area and improved histological integrity), and performance by modulating gut microbiota, optimizing bile acid composition, and enhancing ileal FXR-FGF15 signaling to activate the muscle FGFR4/KLB pathway and inhibit protein degradation. Furthermore, fermented milk produced with F1-7 and F1-3-2 met quality standards and exhibited improved sensory properties. This study provides a mechanistic basis for developing probiotic dairy products and sustainable nutritional strategies for sarcopenia.",
"42531785": "ID: 42531785\nTitle: Curdlan alleviates non-alcoholic fatty liver disease by enriching butyrate-producing gut microbiota-liver axis.\nAbstract: The gut microbiota-liver axis is a critical target for non-alcoholic fatty liver disease (NAFLD) intervention, yet effective strategies to restore gut microbiota balance and mitigate hepatic metabolic inflammation remain limited. Curdlan, a Food and Drug Administration-approved microbial exopolysaccharide, is widely used as a food additive, but its role in modulating the gut-liver axis to combat NAFLD has never been explored. Here, we demonstrate that curdlan alleviates high-fat and fiber-deficient (HFFD) diet-induced NAFLD by orchestrating gut microbiota remodeling and enhancing gut-liver crosstalk associated with the enrichment of butyrate-producing bacteria. In the mouse model of NAFLD, curdlan significantly attenuated hepatic steatosis, inflammation, and M1 macrophage infiltration. Hepatic transcriptome analysis revealed that curdlan modulated immune response and metabolism pathways, as further evidenced by the improvement of the NF\u03baB-PTP1B-Akt signaling axis. Crucially, curdlan reversed gut barrier disruption by enhancing tight junction proteins and enriching butyrate-producing genera (Clostridium_sensu_stricto_1, Anaerovorax, Roseburia, Turicibacter, and others), thereby increasing serum butyrate levels. Integrative correlation analysis revealed a significant correlation between butyrate-producing bacteria, increased serum butyrate levels, reduced serum lipopolysaccharide, and downregulated hepatic proinflammatory cytokines. Strikingly, Clostridium butyricum supplementation recapitulated the protective effects of curdlan, suggesting a role for butyrate in mediating gut-liver interactions. These findings establish curdlan as a novel prebiotic and metabolic modulator with therapeutic potential for NAFLD and support the translational application of functional food additives in metabolic disease management.",

Diosgenin, a steroidal saponin derived from plants of the Dioscorea genus, has demonstrated potential anti-aging properties; however, its role in sarcopenia remains unclear. In this study, naturally aged C57BL/6J mice and a D-galactose (D-gal)-induced senescent C2C12 cell model were employed to systematically investigate the effects of diosgenin on muscle function, satellite cell dynamics, and the sirtuin 1 (SIRT1)/peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PGC-1\u03b1) signaling pathway. Diosgenin treatment significantly improved forelimb grip strength and exercise endurance, increased the gastrocnemius muscle index, and enlarged muscle fiber cross-sectional area in aged mice. Mechanistically, diosgenin upregulated the expression of myokines meteorin-like protein (METRNL) and insulin-like growth factor 1 (IGF-1) at both mRNA and protein levels, increased the number of proliferative satellite cells positive for paired box\u00a07 (Pax7) and Ki67, and enhanced the expression of myogenic markers, including myogenic factor 5 (Myf5), Pax7, and myosin heavy chain II (MyHC II). These effects were mediated by direct activation of SIRT1, leading to deacetylation of PGC-1\u03b1. Notably, pharmacological inhibition of SIRT1 with EX527 markedly abrogated the diosgenin-induced effects. Molecular docking and cellular thermal shift assays further confirmed the direct interaction between diosgenin and SIRT1. Collectively, these findings demonstrate that diosgenin alleviates age-related sarcopenia by activating the SIRT1/PGC-1\u03b1 signaling pathway to promote satellite cell proliferation and myogenic differentiation, highlighting its potential as a promising therapeutic candidate for sarcopenia.",
"42533575": "ID: 42533575\nTitle: Oxytocin receptor neurons in the adBNST modulate maternal-like behavior in mice.\nAbstract: Maternal care plays a pivotal role in the brain and behavioral development of offspring. However, the neural substrates underlying the effects of oxytocin (OT) on maternal-like behavior remain incompletely understood. Using OTR-Cre female mice, fiber photometry was utilized to monitor the calcium signals in oxytocin receptor (OTR) neurons. We observed elevated activity of adBNST (anterodorsal bed nucleus of the stria terminalis) OTR neurons during pup-caring behavior, as indicated by increased calcium signals. Chemogenetic activation of adBNST OTR neurons prolonged duration of licking pups, whereas inhibiting these neurons reduced the time of licking pups and prolonged the latency to retrieve pups. Additionally, microinjection of OT into the adBNST increased the time of licking pups, while administration of an oxytocin receptor antagonist (OTA) suppressed pup-caring behavior. Collectively, these findings not only deepen our understanding of the neural basis underlying maternal-like behavior but also provide a potential target for treating or mitigating aberrant maternal care associated with postpartum depression, anxiety or related disorders. \u6bcd\u6027\u7167\u6599\u5728\u5b50\u4ee3\u5927\u8111\u53d1\u80b2\u53ca\u884c\u4e3a\u53d1\u5c55\u4e2d\u8d77\u7740\u81f3\u5173\u91cd\u8981\u7684\u4f5c\u7528\u3002\u7136\u800c\uff0c\u50ac\u4ea7\u7d20\uff08oxytocin, OT\uff09\u8c03\u63a7\u6bcd\u6027\u6837\u884c\u4e3a\u7684\u795e\u7ecf\u673a\u5236\u5c1a\u672a\u5b8c\u5168\u9610\u660e\u3002\u672c\u7814\u7a76\u5229\u7528 OTR-Cre\u96cc\u6027\u5c0f\u9f20\uff0c\u7ed3\u5408\u5149\u7ea4\u6210\u50cf\u8bb0\u5f55\u6280\u672f\u76d1\u6d4b\u524d\u80cc\u4fa7\u7ec8\u7eb9\u5e8a\u6838\uff08Anterodorsal Bed Nucleus of the Stria Terminalis\uff0cadBNST\uff09\u5185\u50ac\u4ea7\u7d20\u53d7\u4f53\uff08Oxytocin Receptor, OTR\uff09\u795e\u7ecf\u5143\u7684\u9499\u6d3b\u52a8\u3002\u7ed3\u679c\u663e\u793a\uff0c\u5728\u7167\u987e\u5e7c\u5d3d\u8fc7\u7a0b\u4e2d\uff0cadBNST OTR\u795e\u7ecf\u5143\u6d3b\u52a8\u663e\u8457\u5347\u9ad8\u3002\u901a\u8fc7\u5316\u5b66\u9057\u4f20\u5b66\u6fc0\u6d3b\u50ac\u4ea7\u7d20\u53d7\u4f53\u795e\u7ecf\u5143\u53ef\u5ef6\u957f\u5bf9\u5e7c\u5d3d\u7406\u6bdb\u7684\u65f6\u95f4\uff1b\u800c\u6291\u5236\u8fd9\u4e9b\u795e\u7ecf\u5143\u5219\u7f29\u77ed\u5bf9\u5e7c\u5d3d\u7406\u6bdb\u7684\u65f6\u95f4\u5e76\u5ef6\u957f\u8854\u56de\u5e7c\u5d3d\u7684\u6f5c\u4f0f\u671f\u3002\u6b64\u5916\uff0c\u5411adBNST\u5fae\u91cf\u6ce8\u5c04OT\u53ef\u589e\u52a0\u5bf9\u5e7c\u5d3d\u7684\u7406\u6bdb\u65f6\u95f4\uff0c\u800c\u7ed9\u4e88\u50ac\u4ea7\u7d20\u53d7\u4f53\u62ee\u6297\u5242\uff08Oxytocin Receptor Antagonist\uff0cOTA\uff09\u5219\u6291\u5236\u6bcd\u672c\u6837\u884c\u4e3a\u3002\u7efc\u4e0a\u6240\u8ff0\uff0c\u8fd9\u4e9b\u7814\u7a76\u7ed3\u679c\u4e0d\u4ec5\u52a0\u6df1\u4e86\u6211\u4eec\u5bf9\u6bcd\u6027\u884c\u4e3a\u795e\u7ecf\u57fa\u7840\u7684\u7406\u89e3\uff0c\u8fd8\u4e3a\u6cbb\u7597\u6216\u7f13\u89e3\u4ea7\u540e\u6291\u90c1\u3001\u7126\u8651\u53ca\u76f8\u5173\u75be\u75c5\u6240\u5f15\u53d1\u7684\u5f02\u5e38\u6bcd\u6027\u7167\u6599\u884c\u4e3a\u63d0\u4f9b\u4e86\u6f5c\u5728\u9776\u70b9\u3002.",

While its traditional use as a food source for communities in this biome, particularly the almond, is well established, the health benefits of baru have yet to be extensively explored on a broader scale. This study aimed to collect and analyze evidence regarding the nutritional composition of both parts of the baru fruit: (1) pulp and peel, and (2) almond, and their potential effects on human health. The review considered data on chemical composition, alongside studies that investigate health effects. The potential health benefits of baru are significant, underscoring its value as a functional food. The pulp, rich in carbohydrates and insoluble fiber, and the almond, with its high protein content and fatty acid profile, particularly oleic and linoleic acids, stand out. Regarding bioactive compounds, flavonoids are the main compounds identified. Baru is mainly associated with potential prebiotic activity, an improved lipid profile, cardiovascular protection, and reduced oxidative stress. Therefore, this work highlights the potential of baru as a functional food and encourages its incorporation into healthy diets, also contributing to the preservation of Brazilian biodiversity.",

Microglia, the principal immune cells with in the central nervous system (CNS) are pivotal mediators of neuroinflammatory responses via their dynamic transition across a spectrum of polarization states, broadly delineated by pro-inflammatory M1-like and anti-inflammatory M2-like phenotypic profiles. A pathological skew towards pro-inflammatory microglial activation drives and exacerbates disease progression, thereby rendering the modulation of microglial polarization states a promising therapeutic target for neuroprotective intervention. Natural polyphenols have garnered increasing interest owing to their capacity to traverse the blood-brain barrier (BBB), confer neuroprotective effects, and mitigate neuroinflammation. Despite challenges in clinical translation stemming from poor bioavailability and rapid in vivo metabolism, innovative delivery systems are being developed to address these limitations. This review consolidates current evidence regarding the mechanisms by which polyphenols modulate microglial phenotypic balance and polarization states and examines advanced delivery strategies designed to enhance their therapeutic efficacy in neuroinflammatory disorders. By synthesizing these perspectives, we offer novel insights into the potential application of polyphenols in neuroprotective therapies targeting pathological neuroinflammation.",

Accumulating evidence indicates that natural products exert significant cardioprotective effects by coordinately regulating multiple mitochondrial pathways, thereby alleviating myocardial injury and slowing disease progression. This review systematically summarises recent advances in natural metabolites and their rational combination strategies for cardiovascular diseases, with a particular focus on mitochondrial regulation. Representative metabolites, including flavonoids, alkaloids, saponins, and polyphenols, regulate key signalling pathways such as SIRT1/PGC-1\u03b1, AMPK, Nrf2, PINK1/Parkin, and Drp1/MFN2 to restore mitochondrial homeostasis. Importantly, natural metabolite combinations further demonstrate synergistic and complementary effects through coordinated regulation of distinct mitochondrial pathways. For example, EGCG and Rhein cooperatively alleviate myocardial ischemia/reperfusion injury by simultaneously suppressing oxidative stress and TLR4-mediated inflammatory signalling. Collectively, this review highlights the considerable potential of natural products and their rational combinations as therapeutic strategies for cardiovascular diseases through the modulation of mitochondrial function.",

Among the saturated fatty acids, palmitic acid (C16:0) is often a major component and has been implicated in the modulation of inflammation, insulin resistance, and lipid metabolism. In this study, we evaluated palmitic acid intake and overall dietary quality among school-aged children following gluten-free or unrestricted diets, before and after the widespread adoption of \"no palm oil\" labeling. Using 24-h dietary recalls and food frequency questionnaires, we estimated palmitic acid consumption, macronutrient intake, and key health indicators, including body mass index (BMI) z-scores and the Homeostasis Model Assessment of Insulin Resistance (HOMA-IR). Data collected before 2015 and after 2019 were compared to evaluate the dietary and metabolic changes over time. Overall, 124 individuals were included: 62 on a gluten-free diet and 62 on a gluten-containing diet. Each group had 31 participants assessed before 2015 and after 2019. Following 2019, the mean palmitic acid intake was significantly lower (p < 0.001), particularly among celiac children. After 2019, the main dietary sources of palmitic acid shifted toward natural food, particularly dairy products, consistent with a qualitative improvement in fat intake. Variations in sugar consumption among dietary groups may act as a proxy for broader dietary differences related to palmitic acid intake. The gluten-containing diet group reported higher sugar and fiber intakes. Sugar intake correlated positively with BMI z-scores, whereas palmitic acid intake showed an initial association with HOMA-IR (p < 0.05). These changes suggest a progressive alignment with the Mediterranean dietary model, a widely recognized healthy eating pattern, in both children with celiac disease and healthy controls. This shift supports the role of food reformulation, labeling initiatives, and nutritional education in promoting long-term health benefits.",
"42535709": "ID: 42535709\nTitle: Macrophage efferocytosis in pregnancy and pregnancy complications.\nAbstract: Efferocytosis is a vital process during early placental development, which removes apoptotic cells generated through decidualisation and controls inflammation. As pregnancy progresses and levels of apoptotic placental cells increase, macrophage efferocytosis remains essential to maintain a healthy pregnancy. There is mounting evidence that dysfunctional macrophage efferocytosis is implicated in the pathogenesis of multiple pregnancy complications. This includes disorders of malplacentation such as preeclampsia and fetal growth restriction, wherein impaired spiral artery remodelling and inflammation in the decidua impairs placental vascularisation leading to maternal hypertension, or impaired fetal growth. As a shift in macrophage phenotype and cytokine secretion is required for the onset of labour, alterations in phenotype earlier in pregnancy may be associated with preterm birth. In more rare pregnancy complications such as chronic histiocytic intervillositis (CHI), impaired efferocytosis and wound healing by infiltrating intervillous macrophages may contribute to their excessive recruitment into the intervillous space, hindering placental function. In this review, we describe the importance of efferocytosis by various maternal macrophage populations in the placenta and review the evidence of how impaired efferocytosis contributes to pathology. Furthermore, therapeutic targeting of macrophage efferocytosis and how this may be used to prevent or treat obstetric conditions is explored.",

Here we aim to determine how the natural polysaccharide inulin reshapes metabolic stress responses especially in colon cancer cells. In tumor cells treated by inulin, oxidized lipids accumulated in the perimitochondrial region and were accompanied by mitochondrial fragmentation, Golgi dispersion, endoplasmic reticulum (ER) disorganization, lysosomal remodeling, increased mitochondrially encoded cytochrome c oxidase II (MTCO2), and nuclear p21, indicating organelle stress coupled to metabolic reprogramming. Non-malignant cells showed elevated lipid peroxidation but limited necrotic death, consistent with greater metabolic tolerance. YAP/MYC inhibition increased inulin sensitivity. Importantly, ataxia telangiectasia and Rad3-related (ATR) supported stress adaptation, particularly in normal cells. Additionally, inulin decreased nuclear active MYC and YAP and enhanced nuclear androgen receptor (AR). Network pharmacology identified inulin against colon cancer by AR-related hub gene PTGS2 (prostaglandin G/H synthase-2) and validated by a synergistic combination with progesterone. Thus, inulin triggers tumor-selective metabolic stress and disrupts adaptive MYC/YAP, providing a rationale for metabolism-based precision cancer therapy.",

Research indicates that IF enhances insulin sensitivity, facilitates weight reduction and stimulates cellular repair pathways, including autophagy. Physiological adaptations to fasting are reflected in favorable alterations in biomarkers and metabolic processes. This review examines the current evidence on IF by analyzing studies retrieved through schematic searches of the MEDLINE via PubMed database, Embase and ScienceDirect using specific keyword combinations. It focuses on commonly practiced regimens- Time-restricted eating (TRE) (16/8 method), Alternate-day fasting (ADF), the 5:2 intermittent energy-restriction diet and One meal a day (OMAD) approaches and explores their effects on cardiovascular function, metabolic regulation, cognitive performance and longevity. Various IF regimens including the TRE (16/8 method), ADF, the 5:2 diet and OMAD approaches are discussed in relation to their effects on cardiovascular health, cognitive function, metabolic regulation, aging and longevity. While most finding highlight significant health benefits, inconsistencies and methodological limitations are also reported. Mechanistically, IF orchestrates a coordinated metabolic response through modulation of key nutrient sensing pathway such as AMP activated protein kinase (AMPK), mechanistic target of rapamycin (mTOR) and unc-51-like kinase 1 (ULK1). These cascades interact with Sirtuins (SIRT1/3), peroxisome proliferator activated receptor gamma coactivator-1\u03b1 (PGC-1\u03b1) and the transcription factor EB (TFEB) to regulate autophagy, mitochondrial biogenesis, oxidative stress defense and cellular repair. Clinically, these molecular events underpin improvements in glycaemic control, lipid metabolism and inflammatory balance, supporting the therapeutic potential of IF for cardiometabolic disorders, neuroprotection and healthy aging.",

Emerging evidence implicates lipid dysregulation in neurodegeneration, but its extent across FTLD subtypes and how it compares to AD are unclear. Here, we performed integrated lipidomic and proteomic analyses of matched frontal (disease-vulnerable) and occipital (relatively spared) post-mortem cortices from individuals with genetic and sporadic FTLD-TDP, FTLD-tau (Pick's disease, PiD), AD, and controls. FTLD and AD exhibited convergent lipid alterations, including reduced levels of cardiolipins and phosphatidylethanolamines, alongside increased gangliosides, diacylglycerols, cholesterol esters, acylcarnitines, and coenzyme Q, with generally greater changes in FTLD frontal cortex. FTLD displayed additional alterations, including reductions in bis(monoacylglycerol)phosphate, ceramides, phosphatidylserines, phosphatidylinositols, and sulfatides. These lipid changes were accompanied by proteomic alterations involving lysosomal proteins, phospholipases, phospholipid remodeling enzymes, and fatty acid oxidation pathways. Although lipidomic and proteomic signatures were broadly shared across FTLD subtypes, GRN associated FTLD-TDP and PiD showed the most extensive alterations. Triglycerides were selectively reduced in PiD in association with decreased DGAT1 expression, whereas cholesterol esters were elevated across all subtypes except C9orf72 associated FTLD-TDP. These findings identify shared disruptions in lipid homeostasis and lysosomal lipid metabolism across FTLD and AD, highlighting convergent metabolic pathways underlying neurodegeneration.",

Identifying patients at highest risk of developing diabetes facilitates early intervention. There is no consensus on diagnostic criteria, with no single modality or range shown to be most predictive of progression to diabetes. This systematic review and meta-analysis aimed to determine which single or combination biochemical test(s) and definition of pre-diabetes best predict progression to diabetes. Following primary screening of 11 980 papers from MEDLINE, Embase and Global Health, 40 original studies published between 2006 and 2024 looking at adults with pre-diabetes were included. Children, pregnant patient populations and groups with significant morbidity were excluded. Risk of bias was assessed with the JBI Critical Appraisal Checklist. Our meta-analysis demonstrated the highest risk of progression to diabetes in the impaired fasting glucose (IFG) 6.1-6.9 mmol/L group, with an HR of 9.0 (4.6 to 13.5). Descriptive statistics identified the combination of IFG 6.1-6.9 mmol/L + impaired glucose tolerance + HbA1c 6.0%-6.4% had the highest percent incidence of diabetes per year, at 15.2%. Generally, combination tests were associated with higher progression rates. Certain single and combination biochemical test combinations may allow better identification of patients with pre-diabetes likely to progress to diabetes. To our knowledge, this is the first systematic review evaluating all testing combinations of these categories in progression and comparing pre-diabetes states as defined by multiple guidelines. This study (PROSPERO CRD42022312640) did not receive funding.",
"42540517": "ID: 42540517\nTitle: Neurotoxicity of heavy metals across the lifespan: The beneficial role of nutrition from fetus to the elderly.\nAbstract: Heavy metals pose a profound threat to neurological health across all stages of human life, from prenatal development to old age. Heavy metals such as lead, mercury, cadmium, and arsenic are pervasive environmental pollutants that disrupt neural function through mechanisms including oxidative stress, inflammation, mitochondrial dysfunction, and neurotransmitter system imbalances. During critical developmental windows such as fetal growth and early childhood, exposure can impair neurogenesis, synaptic plasticity, and myelination, leading to lifelong cognitive deficits, behavioral disorders, and increased vulnerability to neurodegenerative diseases in later life. Even in adulthood and aging, chronic exposure exacerbates neurodegeneration, accelerating conditions like Alzheimer's and Parkinson's diseases through persistent oxidative damage and inflammatory cascades. This chapter underscores the dual role of nutrition as both a shield and a therapeutic tool against heavy metal neurotoxicity. Key nutrients, such as polyphenols, vitamins, and essential minerals, counteract heavy metal-induced damage by scavenging free radicals, enhancing antioxidant defenses, modulating inflammation, and promoting neuronal repair. By integrating evidence from epidemiological, preclinical, and clinical studies, this chapter emphasizes actionable strategies, such as fortified infant formulas, plant-based proteins, and micronutrient supplementation to reduce heavy metal bioavailability and bolster neurological resilience. Public health initiatives targeting vulnerable populations, alongside policies regulating environmental pollutants, are critical to curbing this silent epidemic. This chapter advocates for a proactive, nutrition-centered approach to safeguarding brain health, demonstrating that dietary interventions are not merely complementary but foundational in combating the pervasive threat of heavy metal neurotoxicity across generations.",

Continuous glucose monitoring system (CGMS) offers the advantage of better understanding of glycaemic variability as compared to oral glucose tolerance test (OGTT). There is scarce data regarding use of CGMS in understanding glycaemic variability in patients of PCOS. Fifty nondiabetic PCOS patients of age group 16-45 years diagnosed by Rotterdam criteria (2003) were included and subjected to CGM for 72 hours. The mean age of participants was 23.32 \u00b1 4.58 years. Family history of diabetes mellitus in a first degree relative was present in 40% patients. On OGTT, dysglycemia was present in 14 patients-5 (10%) had impaired fasting glucose (IFG), 6 (12%) had impaired glucose tolerance (IGT), and 6 (12%) had both IFG and IGT. Glycemic variability and post prandial glycaemic excursion (PPGE) were found to have significant positive correlation with Luteinizing hormone: Follicle-stimulating hormone (LH: FSH) ratio [r = 0.37 (P = 0.008) and r = 0.39 (P = 0.004)], respectively. Fasting and 2-hour OGTT plasma glucose, serum testosterone, mean blood glucose (MBG), eA1c, total PPGE, and PPGE for breakfast values were significantly higher in patients having homeostatic model assessment insulin resistance (IR) >2.5. MBG, eA1c, and PPGE for lunch and dinner were significantly high in patients with family history (FH) of diabetes mellitus (DM). There was no significant difference in CGM metrics among patients with or without hyperandrogenism (HA). CGMS detected high glycaemic variability and exaggerated post meal glycaemic excursions in Indian non diabetic PCOS patients having either positive family history of diabetes mellitus or IR or higher LH: FSH ratio.",
"42542304": "ID: 42542304\nTitle: Fermentation-induced changes in Bupleurum: A study on flavonoids, polyphenols, antioxidant capacity, and metabolomic analysis.\nAbstract: Previous studies have indicated that the process of herbal fermentation can enhance the bioactive components of the plant. Bupleurum, a traditional Chinese herb, is used to treat conditions such as colds and inflammation. This study used Bacillus velezensis PV810342 (with strong enzyme production) to ferment Bupleurum aqueous decoction for 48\u00a0h at 0%, 2%, 4%, 6%, 8%, and 10% inoculation rates. A comparative analysis of the Bupleurum aqueous decoction before and after fermentation revealed that the optimal levels of flavonoids (an increase of 62.7%) and polyphenols (an increase of 21.5%) were achieved with a 4% inoculation rate. There was also a 26.6% improvement in hydroxyl radical scavenging capacity and a 42.07% improvement in ferric reducing antioxidant power. However, there was a significant decrease in DPPH radical scavenging capacity. Metabolomic analysis revealed that B. velezensis PV810342 has been observed to modulate glyoxylate and dicarboxylate metabolism, phenylalanine metabolism, and tyrosine metabolism through co-metabolism, thereby influencing the contents of flavonoids, polyphenols, saponins, fatty acids, terpenoids, and alkaloids. Collectively, these findings suggest that Bacillus velezensis-fermented Bupleurum possesses elevated active components and antioxidant activity, suggesting its potential for further development in managing oxidative stress-related conditions.",
"42542867": "ID: 42542867\nTitle: Characterization of the microbiome and polyphenolic compounds in the medicinal plant Dracocephalum tanguticum.\nAbstract: Dracocephalum tanguticum (Maxim) is rich in various chemical constituents and is widely used in traditional Zang medicine. Endophytes play a direct or indirect role in the biosynthesis of active compounds and plant growth. However, little is known about the characteristics of endophytes and polyphenolic compounds in the various organs of D. tanguticum. In this study, high-throughput sequencing and polyphenol-targeted metabolomics were employed to analyze endophytic community diversity and assembly processes, polyphenolic compound content, and their correlations. The results showed that the endophytic compositions of the leaf and stem organs were similar, and significantly different from that in the root organs; however, the endophytic diversity did not differ significantly across the various organs. Actinobacteriota and Pseudomonadota were the dominant bacterial phyla, Ascomycota and Basidiomycota were the dominant fungal phyla in the various organs, while the dominant endophytic genera were significantly different. The endophytic community assembly was influenced mainly by stochastic processes in the various organs. A total of 75 polyphenolic compounds were identified, and the contents of the polyphenolic compounds in the various organs of D. tanguticum differed significantly. The correlation analysis revealed varying degrees of positive and negative correlation between endophytes and polyphenolic compounds. These findings clarify the characteristics of the endophytes and polyphenolic compounds, and lay a theoretical foundation for the identification and application functional microbiomes in the D. tanguticum.",
"42543059": "ID: 42543059\nTitle: Astaxanthin attenuates skeletal muscle atrophy and mitochondrial dysfunction in streptozotocin-induced diabetic rats.\nAbstract: Diabetes mellitus (DM) induces skeletal muscle atrophy and mitochondrial dysfunction. Although antioxidant supplementation has exhibited beneficial effects on diabetic skeletal muscle, the effects of astaxanthin (AST), a potent antioxidant that protects mitochondrial function, remain unclear. We investigated whether AST supplementation attenuates DM-induced skeletal muscle alterations in streptozotocin (STZ)-induced diabetic rats. Male Wistar rats were assigned to control, DM, and DM\u00a0+\u00a0AST groups. DM was induced via STZ injection, and AST (100\u202fmg/kg/day) was administered orally for 6 weeks. The plantaris muscle was analyzed for morphology, mitochondrial function, oxidative stress, inflammatory status, and signaling pathways related to protein metabolism and atrophy. Diabetic rats exhibited reductions in muscle mass and fiber cross-sectional area, decreases in mitochondrial enzyme activity and mitochondrial protein content, and increased oxidative stress. The expression of pro-inflammatory cytokines was elevated, along with markers associated with ubiquitin-proteasome system-, autophagy-, and apoptosis-related signaling. AST supplementation improved muscle mass and fiber cross-sectional area, partially restored mitochondrial enzyme activity and related protein expression, reduced oxidative stress, and attenuated inflammatory and atrophy-related signaling, without improving hyperglycemia. These findings indicate that AST attenuates DM-induced skeletal muscle atrophy and mitochondrial dysfunction in fast-twitch plantaris muscle. The protective effects of AST appear to be associated with reduced oxidative stress, attenuated inflammation, and attenuation of atrophy-related signaling rather than the restoration of anabolic signaling.",

A phototoxicity model was established on the dorsal skin of SD rats, which were randomly divided into a control group, an IMO group(0.8 mg\u00b7cm~(-2)), a long-wave ultraviolet A(UVA) group(10 J\u00b7cm~(-2)), and an IMO + UVA group. The rats were continuously observed for 72 h, and Draize skin scores were assessed. Hematoxylin-eosin(HE) staining was used to observe histopathological changes, and Verhoeff-Van Gieson(VVG) staining was utilized to evaluate changes in dermal elastic and collagen fibers. Human dermal fibroblasts(HDF) were cultured in vitro and divided into control, IMO, UVA(1 J\u00b7cm~(-2)), and groups of IMO with low, medium, and high doses(1, 2.5, and 5 \u03bcg\u00b7mL~(-1)) + UVA. The CCK-8 assay was used to assess the cell viability. Transcriptomics by RNA-seq was used to analyze the changes in gene expression. Real-time quantitative PCR(RT-qPCR) was used to detect the mRNA expressions of the top 10 senescence-associated genes. Enzyme-linked immunosorbent assay(ELISA) was used to detect the levels of senescence-associated secretory phenotype(SASP) factors like matrix metalloproteinase-3(MMP-3), interleukin(IL)-6, and IL-8. Immunofluorescence was used to evaluate the senescence-associated heterochromatin foci(SAHF) markers like heterochromatin protein 1\u03b3(HP1\u03b3) and trimethylation of histone H3 at lysine 9(H3K9me3). Senescence-associated \u03b2-galactosidase(SA-\u03b2-gal) staining was performed to detect the senescent cells, and Western blot was used to detect the expression and localization of growth arrest and DNA damage-inducible alpha(GADD45A), G_2/M phase-specific cyclin B1(Cyclin B1), and cyclin-dependent kinase 1(CDK1) proteins. Flow cytometry was used to analyze the cell cycle. The siRNA was used to silence GADD45A gene to verify its function. In vivo results show that, compared to the control group, the IMO + UVA group has significantly higher skin damage scores, with stratum corneum loss, inflammatory cell infiltration, reduced collagen fiber density, and abnormal deposition of elastic fibers. In vitro results demonstrate that IMO + UVA significantly inhibits the cell viability of HDF(P<0.05). RNA-seq and RT-qPCR verifications indicate that IMO + UVA significantly upregulate the expressions of senescence-associated genes, with GADD45A gene showing the most significant change. The IMO + UVA group also shows significant increases in SASP factor secretion, SA-\u03b2-gal activity, SAHF formation, and the proportion of cells in the G_2/M phase(P<0.05). Western blot results demonstrate that IMO + UVA promote the expression of GADD45A protein and inhibit nuclear translocation of Cyclin B1, thereby reducing the kinase activity of the Cyclin B1-CDK1 complex. Silencing GADD45A gene effectively alleviates G_2/M phase arrest and cellular senescence phenotype. In summary, IMO in combination with UVA can induce photodamage to the skin and accelerate cellular senescence, and the mechanism may involve G_2/M phase arrest mediated by the activation of the GADD45A/Cyclin B1/CDK1 axis.",
"42543476": "ID: 42543476\nTitle: Synergistic bacterial\u2012fungal interactions modulate the fermentation quality and in vitro degradation rate of triticale silage.\nAbstract: The humid climate and frequent rainfall during the harvest season substantially hinder the utilization of triticale as feed. Although ensiling technology can effectively preserve nutrients, its fermentation quality depends on complex microbial interactions, the core mechanisms of which remain unclear. This study proposes and validates the hypothesis that \"bacterial-fungal synergy\" can enhance silage fermentation. By inoculating triticale silage with Aspergillus niger (AN), Lactiplantibacillus plantarum (LP) or their combination (ANLP) and performing multi-omics analyses, the mechanism underlying this synergistic effect was systematically elucidated in this study. Compared with the control treatment, triticale silage inoculated with ANLP presented significant decreases in the neutral detergent fiber (NDF), acid detergent fiber (ADF), and ammonia nitrogen (NH3-N) contents and significant increases in the water-soluble carbohydrate (WSC), crude protein (CP), and lactic acid (LA) contents (P\u2009<\u20090.05). More crucially, ANLP treatment specifically enriched Delftia, indicating a special functional role for this bacterium in triticale silage. Further metabolomic and correlation analyses revealed that the synergy between A. niger and L. plantarum not only promoted the proliferation of Delftia but also activated the phenylalanine, tyrosine, and tryptophan biosynthesis pathways. This activation drove the synthesis of phenolic acid compounds with antimicrobial and antioxidant activities, such as coumaric acid and indole derivatives. These bioactive metabolites effectively inhibited the growth of harmful microorganisms. In vitro digestibility trials confirmed that the ANLP-treated group achieved the highest dry matter and protein degradation rates, thereby validating the pathway from the microbial mechanism to end-use feed value. Overall, the synergistic effects of bacteria (L. plantarum) and fungi (A. niger) can improve the fermentation quality and nutritional content of triticale by promoting amino acid metabolism and increasing the production of bioactive substances, providing a new strategy for increasing its utilization as a feed resource for ruminants.",
"42543925": "ID: 42543925\nTitle: Hypothyroidism in Nonalcoholic Fatty Liver Disease.\nAbstract: Nonalcoholic fatty liver disease (NAFLD) is a leading cause of chronic liver disease with increasing global prevalence. Thyroid dysfunction, particularly hypothyroidism, has been implicated in its pathogenesis and progression. To evaluate the prevalence and pattern of hypothyroidism in NAFLD patients and assess its association with hepatic steatosis and fibrosis severity using imaging and noninvasive fibrosis scoring systems. This cross-sectional observational study was conducted on 158 adult NAFLD patients at a tertiary care hospital in northern India over 1 year. Patients with significant alcohol intake or other chronic liver diseases were excluded. Hepatic steatosis and fibrosis were assessed by ultrasonography and transient elastography, respectively. Fibrosis severity was categorized using FibroScan and the FIB-4 index. Thyroid function was evaluated by serum TSH, FT3, and FT4. Statistical analysis included intergroup comparisons and correlation assessments using SPSS v26, with p < 0.05 considered significant. Among 158 NAFLD patients, 41.14% were hypothyroid. The prevalence of hypothyroidism increased with disease severity: 71.43% in fibrotic NASH and 44.44% in cirrhosis (FibroScan-based). A dose-response trend was observed between steatosis grade and hypothyroidism, reaching 80% in grade 3 steatosis. FT4 showed a significant positive correlation with liver stiffness (r = 0.432, p < 0.001). Additional associations included positive correlations of liver stiffness with urea and INR, and negative correlations with serum protein, fasting glucose, and LDL. Overall, hypothyroidism emerged as a significant cofactor in NAFLD pathogenesis and fibrosis progression. This study demonstrates a strong association between hypothyroidism and both hepatic steatosis and fibrosis in NAFLD. Routine thyroid function screening is recommended in NAFLD patients, particularly those with metabolic syndrome or suspected fibrosis. Early detection and treatment of hypothyroidism may provide therapeutic benefits in slowing or reversing NAFLD progression.",
"42544286": "ID: 42544286\nTitle: Can increasing footwear bending stiffness ameliorate age-related mechanical and metabolic deficits in walking?\nAbstract: Older adults consume metabolic energy faster than their younger adult counterparts while walking, particularly on sloped terrain. This increased rate is likely in part due to an age-related shift in moment and power production from the ankle joint to the hip. Shifting these mechanics proximally may occur due to older adults losing more mechanical energy at the foot and producing lower ankle joint moments, deficits that are exaggerated when walking uphill or against impeding forces. A promising method to target some of these foot and ankle mechanics differences is increasing footwear longitudinal bending stiffness via carbon fiber insoles. We examined how increasing footwear stiffness alters older adult (9F/10M, 70\u00a0\u00b1\u00a05.9 yrs) walking energetics across slopes. Increasing footwear stiffness reduced the magnitude of negative power from the foot+shoe structures distal to the forefoot, but increased negative power of the foot+shoe structures distal to the hindfoot (foot+shoe complex as a whole). At the ankle, peak joint moment increased by \u223c10% in the stiffest footwear compared with the baseline standardized shoe. Neither knee and hip mechanics nor net metabolic power were consistently affected by footwear stiffness. These results indicate that increasing older adult footwear stiffness via flat carbon fiber insoles attenuates some age-related deficits in foot and ankle mechanics, but does not result in a clear attenuation of the age-related distal to proximal shift in joint mechanics or clear metabolic benefits. The increase in ankle joint moment with stiffer footwear could be useful longer-term as a means to strengthen the calf musculature of older adults. Future work should examine the effects of footwear stiffening on ankle muscle-level outcomes such as force production, excitation, and fascicle mechanics.",
"42544671": "ID: 42544671\nTitle: [Integrative Multi-omics Analysis of the Tnf-Pnpla2-Rictor-Nr1d1 Network Underlying the Hemostatic Action of Bletilla Striata].\nAbstract: By integrating transcriptomics and network pharmacology, we systematically investigated the potential hemostatic mechanism of Bletilla striata (BS). Thirty SPF-grade Kunming mice were randomly divided into three groups (n =10 per group): Control group, Model group, and BS group. The BS group was orally administered Bletilla striata extract (2.48 g/kg) for 7 consecutive days, while the Control and Model groups received an equal volume of 0.5% sodium carboxymethyl cellulose (CMC-Na) solution. On day 7, the Model and BS groups were injected via the tail vein with heparin sodium (0.8 U per mouse) to inducesystemic bleeding. The bleeding time (BT) was measured by tail tip amputation, and coagulation parameters including prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), and plasma fibrinogen (FIB) were measured using a semi-automaticcoagulation analyzer. Liver tissues were collected for total RNA extraction and transcriptome sequencing to identify differentially expressed genes (DEGs) related to coagulation pathways. Network pharmacology was used to construct aprotein-protein interaction (PPI) network, screen hub genes, and perform molecular docking to evaluate the binding affinity between the active component militarineand key target proteins. Compared with the Model group, preventive treatment with BS significantly shortened BT and CT (P <0.01), and reversed coagulation parameters: APTT, PT, and TT were significantly reduced (P <0.01), while FIB levels were significantly elevated P <0.001). Transcriptome analysis showed that the hepatic gene expression profile in the BS group was closer to that of the Control group. Network pharmacologyidentified Tnf, Rictor, Nrld1 , and Pnpla2 askey hub genes involved in the hemostaticprocess, all of which exhibited favorable binding affinity with militarine. Compared to the control group, the Model group showed a significant decrease in hepatic Tnf expression but significant increases in Rictor, Nr1d1 , and Pnpla2. After preventive intervention with Bletilla striata , the hepatic Tnf expression in the mice was significantly increased compared to the Model group, while Rictor, Nr1d1 , and Pnpla2 significantly decreased. These findings were further validated by RT-PCR and molecular docking analyses.

"42544905": "ID: 42544905\nTitle: Effects of vitamin D supplementation on insulin resistance and lipid metabolic profiles in women with gestational diabetes mellitus: A randomized controlled trial.\nAbstract: Gestational diabetes mellitus (GDM) commonly presents as insulin resistance and altered lipid metabolism, with evidence linking vitamin D deficiency to its pathogenesis. In this randomized, double-blind, placebo-controlled trial, 120 pregnant women diagnosed with GDM were assigned to receive either vitamin D3 supplements (2000 IU/day) or a placebo for 3 months. Serum vitamin D status, glycemic control parameters, and lipid profiles were evaluated pre- and post-intervention, adjusting for dietary and exercise confounders. After the 3-month intervention, serum 25-hydroxyvitamin D levels in the vitamin D group were significantly higher than those in the placebo group. Vitamin D supplementation effectively reduced fasting plasma glucose, fasting insulin, and HOMA-IR scores. Simultaneously, it significantly decreased triglycerides and LDL-C levels while increasing HDL-C. Total cholesterol levels showed no statistically significant difference between the two groups. Supplementation with 2000 IU vitamin D per day for 3 months yields significant improvements in glucose homeostasis and lipid metabolism in the GDM population. Vitamin D holds promise as an effective auxiliary treatment to enhance maternal metabolic health.

"42545099": "ID: 42545099\nTitle: Transcriptomic Association of COL3A1+ Fibroblasts With Mechanical Pain-Related Gene Signatures in Triple-Negative Breast Cancer.\nAbstract: Epidemiological data show that approximately 80% of cancer patients experience pain of varying degrees throughout the course of their disease, with nearly one-third experiencing severe pain, significantly impacting their quality of life and the effectiveness of antitumor treatment. Triple-negative (TN) breast cancer tissues typically exhibit increased stromal stiffness and abnormally elevated mechanical stress; these biomechanical alterations may amplify pain signals by activating mechanosensitive channels. Utilizing single-cell RNA sequencing analysis, this study aims to elucidate the potential biological links between fibroblast mechanotransduction and cancer-associated pain, thereby providing a theoretical basis for clinical diagnosis and treatment. Dimensionality reduction and unsupervised clustering were used to identify cell types in TN breast cancer single-cell RNA sequencing data. To assess the association between pain and mechanical stimulation, we constructed a set of gene signatures associated with mechanical stimulation and pain and calculated scores using the Area Under the Curve Cell (AUCell). CellChat and SCENIC were used to reveal the communication networks and transcription factor regulatory mechanisms of fibroblast subtypes. COL3A1+ fibroblasts derived from TN breast cancer are highly involved in biological processes such as extracellular matrix remodeling, collagen fiber formation, and mechanotransduction. To assess the association between pain and mechanical stimulation, we constructed a gene signature set related to mechanical stimuli and pain and calculated corresponding scores using the AUCell tool. Cell communication studies showed that COL3A1+ fibroblasts interact extensively with epithelial cells and other cells through laminin and collagen signaling pathways, potentially leading to mechanotransduction remodeling of the TN breast cancer microenvironment. COL3A1+ fibroblasts demonstrate enhanced transcriptional profiles pertinent to collagen deposition and cytoskeletal reorganization, which are correlated with mechanotransduction signaling and may be connected with mechanical sensitivity in cancer-related pain. This study systematically characterizes the potential relationship between fibroblast-associated mechanotransduction characteristics and pain-related gene signatures at the single-cell level in TN breast cancer. These findings offer hypothesis-generating insights into the molecular landscape of tumor-associated pain, although additional experimental and clinical validation is necessary.",
"42545432": "ID: 42545432\nTitle: Hypertrophic cardiomyopathy-linked Tnnc1 variants are associated with distinct myopathic changes in slow skeletal muscle of mice.\nAbstract: Inherited hypertrophic cardiomyopathy (HCM) is considered a disease of the cardiac sarcomere and caused by pathogenic variants present in genes that encode sarcomeric proteins. The human TNNC1 gene is a designated HCM-susceptibility gene encoding the troponin C (TnC) protein, which is expressed in both cardiac and type I slow skeletal muscles and abbreviated as cTnC and ssTnC respectively. HCM patients have been reported to exhibit skeletal muscle weakness and reduced exercise tolerance. Patients bearing TNNC1 cardiac pathogenic variants also express it in type I fibers of their slow skeletal muscles. We hypothesized that the presence of TNNC1 HCM variants in type I fibers may decrease force generating capabilities and alter fatigue resistance of slow skeletal muscles. To address this, we examined the impact of HCM Tnnc1 variants in the soleus muscles of two HCM knock-in mouse models A8V+/-, A8V-/-, and C84Y+/- and their respective wild type (WT) controls. At high stimulation frequencies, we found that A8V-/- soleus muscles had lower tetanic force production than WT, however no differences in fatigue when comparing fatigue indices for either of the variants. The muscles were evaluated by comparing % specific force (N/cm2)-variant and both A8V-/- and C84+/- had increased responsiveness at low stimulation frequencies. Fiber type analysis uncovered an increase in abundance of type I fibers in A8V-/- soleus, however no other differences were observed in fiber-type percentage of either mouse model. Comparison of the cross-sectional areas (CSA) of type I fibers in soleus muscles revealed lower average values for A8V+/+ and A8V-/-, however an increase in C84Y+/- relative to controls. Examination of the CSA of type IIa fibers uncovered decreased values for both A8V+/- and A8V-/- with no changes in C84Y+/- soleus. Histological evaluation of A8V+/- and A8V-/- soleus muscles revealed central nucleation and the detection of embryonic myosin heavy chain by immunofluorescence suggested the presence of mild regeneration. In contrast, no histopathological changes were detected in the C84Y+/- soleus muscle. Serum myokines were also measured to assess systemic impacts of the pathogenic variants and alterations in the physical activity of the mice but no significant changes were found. Taken together our results suggest that the HCM A8V variant alters force production in soleus muscle that may be attributed to fiber atrophy and heightened pathophysiology.",
"42547042": "ID: 42547042\nTitle: Integrated Transcriptome and Metabolome Analysis of Meat Quality Differences in Longissimus Dorsi Muscle Between New Zealand White Rabbits and Rex Rabbits.\nAbstract: Rabbit meat is widely recognized for its favorable nutritional properties, while the molecular mechanisms underlying differences in meat quality between New Zealand White rabbits and Rex rabbits are essential for rabbit production. In this study, a total of 120 healthy 13-week-old rabbits (60 per group) were used to evaluate meat quality traits. The longissimus dorsi muscle (LDM) was then collected for transcriptomic and metabolomic analyses. The results showed that New Zealand White rabbits exhibited significantly higher live weight before slaughter, eviscerated weight, semi-eviscerated weight, and pH24 (p\u2009<\u20090.01), whereas Rex rabbits displayed higher cooking loss (p\u2009<\u20090.01) and intramuscular fat content (p\u2009<\u20090.05). Metabolomic profiling identified 218 differential metabolites (DMs), which were mainly enriched in amino acid biosynthesis and the pentose phosphate pathway, including key metabolites such as DL-arginine, gallic acid, and lipid-related compounds. Transcriptomic analysis identified 227 differentially expressed genes (DEGs) enriched in pathways associated with muscle development and meat quality, including oxidative phosphorylation, FoxO, and MAPK signaling pathways. Key DEGs, such as MYH13, HOXA13, and PDK4, were associated with muscle fiber formation and fat deposition. Integrated analysis revealed that 34 DEGs and 24 DMs were co-enriched in 26 pathways, with strong correlations observed between oxidative phosphorylation-related genes and energy metabolites, as well as between collagen-associated genes and amino acids. These findings establish a gene-metabolite regulatory network underlying breed-specific differences in meat quality and identify potential molecular markers to improve rabbit meat quality and to better understand muscle metabolism across different rabbit breeds.",
"42547437": "ID: 42547437\nTitle: [Effects and mechanisms of PIT on wound healing of full-thickness skin defects in diabetic mice].\nAbstract: Objective: To investigate the effects and mechanisms of polyvinyl alcohol/ionic liquid-tannic acid composite hydrogel (PIT) on wound healing of full-thickness skin defects in diabetic mice. Methods: This study was an experimental research involving grouped design and repeated measurements. An ionic hydrogel matrix crosslinked by polyvinyl alcohol-4-(1H)-vinylimidazole-1-methylene benzoic acid and oxidized hyaluronic acid was prepared, and tannic acid was loaded via Cu2+ chelation to construct PIT. A 1,1-diphenyl-2-picrylhydrazyl (DPPH) solution was prepared and reacted respectively with tannic acid and PIT for 24 hours. An ultraviolet spectrophotometer was used to detect the DPPH radical scavenging rate. According to the random number table method (the same grouping method below), mouse macrophage RAW264.7 cells were divided into a phosphate buffered saline (PBS) group cultured with PBS, as well as a hydrogen peroxide group and a PIT group, in which cells were first treated with hydrogen peroxide for 12 hours and then respectively cultured under routine condition and with PIT. After 24 hours of culture, the fluorescent probe method was adopted to detect the intracellular reactive oxygen species (ROS) level. Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 25923, methicillin-resistant Staphylococcus aureus (MRSA) BNCC 337371, and human umbilical vein endothelial cells (HUVECs) were collected and all divided into PBS group, tannic acid (TA) group, and PIT group, which were cultured with PBS, TA solution, and PIT, respectively. After 12 hours of bacterial culture, the plate counting method was used to count bacterial colonies; after 24 hours of cell culture, the tube formation assay was performed to measure the total tube length, the number of branching nodes, and the number of branches. The sample size of all the above experiments was 3. Eighteen 8-week-old male Kunming mice were selected and divided into PBS group, TA group, and PIT group (with 6 mice in each group) to establish a full-thickness skin defect wound model of diabetes (with one wound in each mouse). At post injury day (PID) 0 (immediately), the wounds of mice in PBS group, TA group, and PIT group were treated respectively with PBS, TA solution, and PIT by topical application, and then the dressings were changed daily. The wound healing status was observed at PID 0, 4, 8, and 12, and the wound healing rates at PID 4, 8, and 12 were calculated. At PID 12, wound tissue was harvested. Hematoxylin-eosin staining was performed to observe the status of wound re-epithelialization and to measure the thickness of newly formed epithelium. Masson staining was performed to observe the deposition of collagen fibers in wounds and to calculate the proportion of collagen fiber-positive area. Results: After 24 hours of reaction, the DPPH radical scavenging rate of PIT was significantly higher than that of TA (t=16.35, P<0.05). After 24 hours of culture, the ROS level of RAW264.7 cells in hydrogen peroxide group was significantly higher than that in PBS group (P<0.05), and the ROS level of RAW264.7 cells in PIT group was significantly lower than that in hydrogen peroxide group (P<0.05). After 12 hours of culture, the bacterial colony counts of Escherichia coli, Staphylococcus aureus, and MRSA in PIT group were significantly less than those in PBS group and TA group (P<0.05). After 24 hours of culture, compared with those in PBS group and TA group, the total tube length of HUVECs in PIT group was significantly increased (with P values both <0.05), and the number of branching nodes and the number of branches increased significantly (with P values all <0.05). From PID 0 to 12, the wounds of mice in all three groups healed gradually. At PID 4, 8, and 12, the wound healing rates of mice in PIT group were (31.6\u00b12.0)%, (51.8\u00b12.5)%, and (97.9\u00b11.5)%, respectively, which were significantly higher than (18.6\u00b10.6)%, (39.5\u00b12.0)%, and (74.6\u00b12.0)% in PBS group and (21.5\u00b11.1)%, (40.7\u00b10.8)%, and (85.3\u00b12.1)% in TA group (P<0.05). At PID 12, the wound re-epithelialization of mice in PBS group was incomplete, and collagen fibers were sparsely distributed with disordered arrangement; the degree of wound re-epithelialization of mice in TA group was higher than that in PBS group, and collagen fibers were distributed in bundles with loose arrangement; the degree of wound re-epithelialization of mice in PIT group was higher than that in TA group, and collagen fibers were densely and orderly arranged in layers. At PID 12, compared with those in PBS group and TA group, the thickness of newly formed epithelium in wounds of mice in PIT group was significantly increased (with P values both <0.05), and the proportion of collagen fiber-positive area was significantly increased (with P values both <0.05). Conclusions: PIT significantly accelerates the wound healing of full-thickness skin defects in diabetic mice through multiple mechanisms driven by metal ion chelation including antibacterial, antioxidant, and pro-angiogenesis activities, thereby improving the quality of tissue repair. \u76ee\u7684\uff1a

"42547443": "ID: 42547443\nTitle: [Research progress on the role of calcitonin gene-related peptide in the repair of diabetic wounds].\nAbstract: Diabetic wounds are a severe complication of diabetes, which can lead to amputation or even mortality in severe cases. While normal wound healing consists of four phases: hemostasis, inflammation, proliferation, and remodeling, diabetic wounds tend to become chronic and refractory primarily due to a prolonged inflammatory phase. In diabetic wounds, insufficient synthesis and release of endogenous calcitonin gene-related peptide (CGRP) is a critical upstream mechanism underlying the disrupted neuro-immune communication, the persistent inflammation, and the arrested wound healing process. In contrast to pure skin defect wounds, where CGRP is rapidly upregulated after injury, CGRP remains persistently low in diabetic wound tissue, consequently failing to drive macrophage polarization towards the M2 phenotype or promote vascular maturation and collagen fiber deposition in the later phase of inflammation. In the early inflammatory phase, CGRP exerts pro-inflammatory effects by enhancing angiogenesis and modulating macrophage polarization. In the late inflammatory phase, CGRP upregulates thrombospondin-1, promotes neutrophil apoptosis and phagocytic clearance, thereby inhibiting excessive inflammatory response and shifting the wound microenvironment from a pro-inflammatory state to a pro-reparative state. Restoring CGRP signaling reconstructs the neuroimmunomodulation axis and improves wound repair while relieving diabetic neuropathic pain. Engineered CGRP combined with intelligent delivery systems offers promising prospects for diabetic wound therapy. However, large-scale clinical trials are still required to validate its clinical efficacy and safety.

To investigate the time-of-day effects of high-intensity interval resistance training (HIRT) on metabolism, adiposity, and adipogenic markers, male Swiss mice (n\u2009=\u2009111) were allocated to control or HIRT groups during the light (C6 and T6) or dark phase (C18 and T18). HIRT was performed for 8\u2009weeks (3 sessions/week) on a ladder at 90% of maximal load until exhaustion. Metabolic biomarkers, adiposity, adipocyte morphology, and protein expression of PPAR\u03b3 and adiponectin were assessed. Maximal strength increased in trained groups. Training-time interactions were observed for triglycerides and total cholesterol, with higher values in T6 than in C6 and T18. Glucose and PPAR\u03b3 were higher during the dark phase. PPAR\u03b3 was also higher in trained than control groups, irrespective of the time of day. HIRT reduced adiposity across multiple depots regardless of training time. No significant differences were observed for adipocyte area, adiponectin, insulin, or HOMA-IR. HIRT reduced adiposity independently of training time, suggesting that chronic adaptations in adipose tissue were primarily driven by the training. However, time of day modulated metabolic responses, particularly lipid metabolism.",

Paeoniflorin (PF), a bioactive compound from Paeonia lactiflora, has shown hepatometabolic effects in experimental studies, but its overall efficacy in NAFLD models remains unclear. We searched PubMed, Embase, Web of Science, the Cochrane Library, CNKI, Wanfang, VIP, and CBM from inception to January 2026 for controlled animal studies evaluating PF in diet-induced NAFLD models. Two reviewers independently performed study selection, data extraction, and risk-of-bias assessment using SYRCLE's tool. Weighted mean differences or standardized mean differences with 95% confidence intervals were pooled using random-effects models. Ten studies were included, all using diet-induced models. PF treatment was associated with improvements in lipid metabolism, liver injury, glucose homeostasis, inflammation, and oxidative stress, including reductions in total cholesterol, triglycerides, low-density lipoprotein cholesterol, alanine aminotransferase, aspartate aminotransferase, body weight, fasting blood glucose, insulin resistance indices, tumor necrosis factor-\u03b1, and malondialdehyde, together with increased superoxide dismutase activity. High-density lipoprotein cholesterol showed no consistent improvement. Mechanistic findings suggested that PF may activate AMP-activated protein kinase, inhibit sterol regulatory element-binding protein-1c/fatty acid synthase-mediated lipogenesis, and modulate inflammatory and oxidative-stress pathways. However, substantial heterogeneity and incomplete reporting of randomization, allocation concealment, and blinding limited confidence in the evidence. PF showed promising preclinical effects in NAFLD, but further well-designed animal studies and clinical investigations are needed to clarify dose-response relationships, safety, and translational relevance.",

The sodium-glucose cotransport-2 inhibitor empagliflozin (EMPA) may improve metabolic parameters beyond glycemic control. This systematic review critically evaluated the effects of EMPA on anthropometric and metabolic outcomes in overweight or obese subjects without diabetes and identified key areas for future research. This systematic review included studies identified through searches of five databases (Scopus, Web of Science, PubMed, Google Scholar, and the Cochrane Library) from January 2023 to May 2026. Following duplicate removal and PRISMA-guided screening, 27 studies were included (7 randomized controlled trials and 20 animal studies). Studies were excluded if they involved diabetic populations, lacked appropriate comparator groups, or did not meet predefined eligibility criteria. The Cochrane and SYRCLE tools were used to assess the quality of human and animal evidence, respectively. Animal studies primarily used EMPA doses of 8-30\u2009mg/kg/day, whereas human trials employed fixed clinical doses of 10-12.5\u2009mg daily. In human investigations, EMPA significantly lowered body weight with notable improvements in fasting glucose. Preclinical studies largely supported these findings and additionally demonstrated improvements in hepatic steatosis, lipid metabolism, and inflammatory markers. Proposed mechanisms included modulation of FGF21 signaling, hepatic PDK4 expression, hypothalamic neuropeptides, NF-\u03baB activity, mitochondrial function, and gut microbiome composition. Even in the absence of diabetes, EMPA shows potential for improving anthropometric and metabolic indices. However, clinical evidence remains limited and further human trials are needed to confirm its long-term safety, efficacy, and underlying molecular mechanisms.",
"42549200": "ID: 42549200\nTitle: Differential shaping of equine gut microbiota structure and function by breed and feeding regimen.\nAbstract: The gut microbiota plays an essential role in host energy metabolism and immune function. Horses are non-ruminant herbivores that rely heavily on hindgut microbial fermentation to meet their energy requirements. However, the relative contributions of host genetic background (breed) and environmental factors (feeding regimen and geographical location) to shaping the equine gut microbiota remain poorly understood. In this study, 16S rRNA gene sequencing and functional prediction analysis were performed on 139 equine fecal samples to systematically investigate the differential effects of breed and feeding regimen on the gut microbiota. Samples were collected from 30 Thoroughbreds (TH), 31 stabled hybrid horses (HH1), 30 grazing hybrid horses (HH2) (with HH1 and HH2 sired by Thoroughbreds out of Mongolian mares), 32 Mongolian horses (MH), and 16 Warmblood horses (WBH1 and WBH2). Alpha and beta diversity analyses, taxonomic profiling, and PERMANOVA were used to assess microbial composition and the contributions of different factors. Alpha diversity analysis revealed that the richness and diversity of the TH, HH1, HH2, and MH groups were significantly higher than those of the Warmblood horses (p\u202f<\u202f0.001), with Mongolian horses exhibiting the highest diversity and the hybrids showing intermediate levels between their parental breeds. Regarding taxonomic composition, the TH, HH1, HH2, and MH groups shared a microbial structure dominated by Firmicutes and Bacteroidota, yet each possessed distinct characteristics: Thoroughbreds were enriched with Treponema; Mongolian horses harbored the highest abundances of Rikenellaceae_RC9_gut_group and NK4A214_group; and the grazing hybrid horses developed a fiber-degrading bacterial community centered on Ruminococcus and Fibrobacter, demonstrating breed-specific microbial features. In contrast, the Warmblood horses exhibited a gut microbiota with distinct features characterized by significantly reduced microbial diversity and core fiber-degrading genera, concomitant with an enrichment of environmental-associated bacteria from the phylum Proteobacteria (e.g., Acinetobacter, Stenotrophomonas) and other genera (e.g., Comamonas, Brevundimonas). PERMANOVA analysis further quantified the contributions of different factors: breed explained 44.8% of the total variation (R\u00b2 = 0.448, p < 0.001), followed by feeding regimen (10.3%, p < 0.001) and geographical location (2.7%, *p* < 0.01), confirming breed as the predominant factor. This study provides evidence that breed establishes the foundational framework of the gut microbiota, while feeding regimen performs fine-tuning functions. We also systematically characterized the unique microbial composition of Warmblood horses, offering a scientific basis for breed-specific health management, precision nutritional interventions, and future disease risk monitoring in horses. Although all horses appeared clinically healthy, the distinct microbial composition observed in Warmblood horses warrants further investigation to determine its biological significance.",

Participants were categorized as metabolic syndrome (MetS) or non-MetS according to the International Diabetes Federation criteria. Subjects were further divided into pre-pubertal, mid-pubertal, and post-pubertal groups. the cohort comprised 188 females and 176 males, with a median age of 12.7 years and a median BMI of 29.37 kg/m\u00b2. MetS was diagnosed in 111 participants (30.5 %), with a prevalence of 19.8 % in pre-pubertal, 34.8 % in mid-pubertal, and 38.1 % in post-pubertal individuals. Participants with MetS had higher NC and NC z-scores, BMI, waist circumference (WC), hip circumference (HC), waist-to-height ratio (WHtR), and systolic and diastolic blood pressure. They also had higher fasting triglycerides, uric acid, fasting plasma glucose, insulin levels, and HOMA-IR. NC demonstrated significant correlations with age, BMI, WC, HC, and metabolic parameters. In multivariate logistic regression analysis, NC emerged as an independent predictor of MetS. Threshold NC values indicative of MetS were identified as 32.75 cm (pre-pubertal), 35.50 cm (mid-pubertal), and 36.25 cm (post-pubertal). this study shows that NC is markedly increased in children and adolescents with MetS and independently predicts MetS. Moreover, our findings indicate that associations between NC and cardiometabolic risk factors, supporting NC as a practical marker for cardiometabolic risk stratification in pediatric obesity.",

Natural products rich in polyphenols may serve as promising complementary preventive strategies. This study investigated the antiurolithiatic and renoprotective effects of Rhus coriaria fruit extract in an ethylene glycol-induced rat model of nephrolithiasis. Forty-two male rats were randomized into seven groups (n\u2009=\u20096): control, ethylene glycol (EG), EG\u2009+\u2009potassium citrate, R. coriaria 250\u00a0mg/kg/day, R. coriaria 500\u00a0mg/kg/day, EG\u2009+\u2009R. coriaria 250\u00a0mg/kg/day, and EG\u2009+\u2009R. coriaria 500\u00a0mg/kg/day. Nephrolithiasis was induced with 1% ethylene glycol for 28 days. Serum biochemistry, urinary lithogenic parameters, oxidative stress markers including total antioxidant status (TAS), total oxidant status (TOS), superoxide dismutase (SOD), catalase (CAT), and malondialdehyde (MDA), histopathology, and immunohistochemical expression of kidney injury molecule-1 (KIM-1) and osteopontin (OPN) were evaluated. Phytochemical characterization of the extract was performed by high-performance liquid chromatography coupled with diode-array detection (HPLC-DAD). Gallic acid was identified as the predominant phenolic constituent, together with smaller amounts of protocatechuic acid and ellagic acid. Ethylene glycol significantly increased urinary lithogenic parameters, oxidative stress indices, crystal deposition, tubular injury, and OPN expression. Treatment with R. coriaria significantly reduced urinary oxalate and calcium levels, improved TAS, SOD, and CAT levels, lowered TOS and MDA concentrations, and markedly attenuated crystal deposition, inflammation, and tubular dilatation. OPN expression was substantially decreased in treated groups, whereas KIM-1 showed a decreasing trend. Protective effects were more pronounced at the 500\u00a0mg/kg/day dose. R. coriaria fruit extract exerted significant antiurolithiatic and renoprotective effects in experimental calcium oxalate nephrolithiasis. These findings suggest that R. coriaria may represent a potential adjunctive strategy for calcium oxalate stone disease.",

Given that CuxNi3-x(HITP)2 has demonstrated large specific surface area, both in-plane and out-of-plane charge transfer ability, narrowed band gap, and enhanced separation of holes and electrons, it can be simultaneously employed as the superior ECL emitter and bioplatform for anchoring single-strand DNA (ssDNA), thus improving the detection sensitivity toward Salmonella. The CRISPR/Cas12a-based system can specifically recognize the target sequence of Salmonella and activate the nuclease activity of Cas12a, and the activated Cas12a possesses trans-cleavage ability toward ssDNA. The CuxNi3-x(HITP)2 emitter is then released, resulting in the decline of the ECL response. The developed CuxNi3-x(HITP)2-CRISPR/Cas12a-based ECL biosensor exhibits the ultralow detection limit of 0.25 CFU mL-\u20091 in the linear range from 1.0 CFU mL-\u20091 to 106 CFU mL-\u20091, significantly lower than those of reported ones. Furthermore, the developed biosensor exhibits outstanding overall biosensing properties with high selectivity, favorable reproducibility and stability, together with promising practical applicability for the determination of Salmonella in a variety of foodstuffs.",
"42550891": "ID: 42550891\nTitle: Adenosine 2A receptor drives microglial efferocytosis to accelerate white matter repair and functional recovery after stroke.\nAbstract: Although reperfusion therapy effectively restores blood flow to occluded brain arteries after ischemic stroke, many patients develop persistent white matter injury, a major contributor to long-term neurological disability. Currently, there are few approved clinical therapies that specifically target white matter repair to enhance functional recovery after stroke. We demonstrated that microglial adenosine 2A receptor (A2AR) is essential for spontaneous white matter regeneration after ischemic injury in mice. Deletion of A2AR in microglia specifically impaired chronic-phase repair without altering the severity of acute ischemic injury. Pharmacological activation of A2AR signaling with blood-brain barrier-permeable agonistic micelles during the early reperfusion phase enhanced white matter structural repair and led to sustained improvements in cognitive and sensorimotor function in mice. Mechanistically, A2AR activation promoted microglial efferocytosis of apoptotic cells and myelin debris in the lesioned white matter, thereby limiting secondary necrosis-induced inflammation, enhancing neurotrophic factor release, and establishing a reparative microenvironment conducive to oligodendrocyte precursor cell differentiation and remyelination. Moreover, A2AR signaling engaged HIF1\u03b1-dependent metabolic reprogramming to increase glycolysis, thereby providing the energetic support required for efficient and sustained efferocytosis. Together, these findings identify A2AR as a critical regulator of microglia-mediated white matter repair and a promising therapeutic target for enhancing regeneration after stroke.",
"42551759": "ID: 42551759\nTitle: Fatty acids and breast cancer: Epidemiology, subtype-specific metabolism, immune regulation, and clinical translation.\nAbstract: Fatty acids (FAs) are bioactive dietary and metabolic molecules that participate in membrane architecture, energy homeostasis, inflammatory signaling, gene regulation and immune function, all of which intersect with breast cancer (BC) risk, progression and treatment response. In this narrative review we integrate epidemiological, clinical, translational and mechanistic evidence on the role of FAs in BC. Saturated, monounsaturated, trans- and polyunsaturated FAs (PUFAs) are treated as distinct biological exposures rather than interchangeable measures of total fat intake. Similarly, evidence from dietary assessment, circulating biomarkers, erythrocyte membrane composition, adipose tissue stores and tumor lipid signatures is interpreted separately, because each captures exposure and biology at a different level. BC subtypes differ in FA synthesis, uptake, oxidation, storage and remodeling: luminal tumors are frequently linked to hormone-regulated lipogenesis, human epidermal growth factor receptor 2 (HER2)-positive tumors to growth-factor-driven lipid metabolism, and triple-negative tumors to exogenous FA uptake, inflammatory lipid mediators and ferroptosis-related vulnerabilities. FA-derived mediators also shape immune-cell polarization, cytokine signaling and the tumor microenvironment, and dietary FAs may reshape the gut microbiota; the fiber-derived short-chain FAs it produces, distinct from dietary FAs, likewise help regulate immune and inflammatory tone. Clinical data suggest possible roles for fat-quality modification and selected n-3 PUFA interventions, but findings are heterogeneous and not yet sufficient to support routine biomarker-guided precision onco-nutrition. Candidate biomarkers, such as erythrocyte n-6:n-3 composition, require prospective validation before clinical implementation. FA biology thus represents a modifiable but complex axis in BC prevention, tumor biology and supportive care.",

Serum free testosterone (FT) reflects the biologically active fraction of circulating testosterone. Accurate assessment of FT allows for precise identification of hyperandrogenism and provides critical guidance for the diagnosis of PCOS. Women with PCOS and normal controls (NCs) were included in this study. Fasting serum samples were collected during the early follicular phase to evaluate key clinical parameters, and FT levels were quantified using liquid chromatography\u2012tandem mass spectrometry (LC\u2012MS/MS). The diagnostic value of FT for identifying PCOS was assessed using Spearman's correlation analysis and receiver operating characteristic curves. A total of 202 women were included in the PCOS group, 121 were included in the NC group. Total testosterone (TT), free androgen index (FAI), and FT levels were significantly greater in the PCOS group than in the NC group. Both FAI and FT were positively correlated with body mass index (BMI), triglycerides, low-density lipoprotein cholesterol, fasting insulin and the homeostasis model assessment for insulin resistance; and were negatively correlated with high-density lipoprotein cholesterol. Following age and BMI adjustments, the area under the curve (AUC) for FT (AUC\u2009=\u20090.886) was greater than that for TT (AUC\u2009=\u20090.856) or FAI (AUC\u2009=\u20090.864). Compared with conventional assessments of TT and FAI, LC-MS/MS-based measurements of FT demonstrate superior diagnostic performance for identifying PCOS. Both FT and FAI are associated with obesity and the features of metabolic syndrome in PCOS patients.",

Over the past decade, the microbiota-gut-brain axis (MGBA) has emerged as a systems-level pathophysiological framework that explains the chronic neuroinflammation, hypothalamic-pituitary-adrenal axis hyperactivity, and impaired neuroplasticity that characterize treatment-resistant mood disorders. Short-chain fatty acids (SCFAs) are key molecular mediators in MGBA signaling, exerting epigenetic regulation through the inhibition of histone deacetylase, suppression of microglial toll-like receptor 4/nuclear factor-kappa B signaling, reinforcement of intestinal and blood-brain barrier integrity, and rebalancing of tryptophan-kynurenine metabolism. A few small randomized controlled trials and meta-analyses have reported that restoring SCFA output using next-generation psychobiotics (Faecalibacterium prausnitzii, Akkermansia muciniphila, and Clostridium butyricum), prebiotic-rich dietary patterns, defined synbiotics, and direct postbiotic supplementation is associated with symptom improvement, although the evidence base remains preliminary, and have been proposed as candidate prognostic biomarkers. This narrative review synthesizes 2022 to 2026 mechanistic and clinical evidence on SCFA-producing psychobiotics in mood disorders; integrates these findings within a clinical nutrition framework that positions dietary fiber, microbiota-accessible carbohydrates, and targeted psychobiotic supplementation as legitimate adjuncts to conventional psychopharmacology; and discusses the translational challenges of strain specificity, dosing variability, and precision-psychobiotic medicine. Nevertheless, current evidence remains dominated by preclinical models, with human trials constrained by size, duration, and number.",

In this study, we investigated whether high methoxyl pectin (HMP), a soluble dietary fiber found in fruits/vegetables and an additive for the food industry would impact \u03b2-carotene bioaccessibility under various physiological digestive conditions, following the INFOGEST gastrointestinal model. Concentrations of pancreatin plus bile salts and shear forces (simulated by varying water bath rounds/min. and glass bead addition) were modified in the presence (1.15\u00a0mg/mL digesta) and absence of HMP. Endpoints measured in the digesta included \u03b2-carotene bioaccessibility, surface tension, viscosity, micelle size, zeta potential, and triglyceride lipolysis. Adding HMP reduced overall bioaccessibility of \u03b2-carotene from 32.1\u00b16.2% to 24.1\u00b15.7% (p<0.001). All other parameters also had a significant impact on the bioaccessibility of \u03b2-carotene, that is, bile/pancreatin concentration (p<0.001), water bath shaking speed (p<0.001), and glass beads (p\u00a0=\u00a00.001). Surface tension, viscosity, and micelle size were less strongly affected by HMP addition (p<0.05), though not triglyceride lipolysis. The inhibitory effect of HMP varied depending on bile/pancreatin concentration and shear-forces, with strongest reductions when \u03b2-carotene bioaccessibility was highest at onset.",

This study assessed the dose-dependent effects of dried tomato pomace powder (TPP) as a dietary additive on the growth performance, feed efficiency, carcass traits, haematological indices and economic returns of Sonali chickens under tropical conditions in Bangladesh. A total of 180, one day-old Sonali chicks were randomly allocated to four dietary treatments, T0 (basal diet), T1 (basal diet\u00a0+\u00a02% TPP), T2 (basal diet\u00a0+\u00a04% TPP) and T3 (basal diet\u00a0+\u00a06% TPP), with three replicates of 15 birds each, and reared for 63 days at the Central Poultry Farm, HSTU, Dinajpur, Bangladesh. The T3 group achieved the highest final live body weight, the greatest weight gain and the most efficient feed conversion, followed by T2, T1 and T0 (p\u00a0<\u00a00.05). Carcass weight and breast, thigh and drumstick yields were significantly higher in T3. Blood analysis showed significantly lower total cholesterol and LDL together with higher HDL in the T3 group. The economic analysis indicated that T3 generated the highest net profit per bird, differing significantly from T0 (p\u00a0<\u00a00.05). Supplementing the diet with dried TPP at 6% significantly improved growth performance, carcass quality, lipid metabolism and financial returns in Sonali chickens, indicating that it is a viable, low-cost functional feed supplement for tropical poultry production systems.",

This review critically examines the microbiology of cigar fermentation through a dual-axis framework organized around beneficial metabolic functions and detrimental spoilage potential, each resolved into microbial identity, biochemical mechanism, and environmental modulation dimensions. We synthesize evidence from culture-dependent and culture-independent studies on microbial community assembly and succession, where Bacillus, Staphylococcus, and Aspergillus emerge as core fermentation genera, and evaluate the complementary three-pathway system - macromolecular enzymatic degradation, targeted biotransformation of tobacco alkaloids and polyphenols, and de novo biosynthesis of aroma-active volatiles - that drives flavor and quality enhancement. We further analyze the contrastive microbial balance governing tobacco-specific nitrosamine (TSNA) formation, where nitrate-reducing bacteria compete with nitrate-assimilating and nitrite-scavenging microorganisms to determine the net TSNA load. In parallel, we critically examine the mould spoilage microbiology of cigar fermentation, identifying the environmental thresholds - humidity above 80% RH, water activity above 0.85, and inadequate aeration - that select for mycotoxigenic Aspergillus and Penicillium species producing aflatoxins and ochratoxin A at levels that persist into the finished product. We survey emerging biotechnological strategies spanning bioaugmentation with defined starter cultures, biostimulation through environmental optimization, and biocontrol of spoilage fungi, and identify five critical research gaps - including the absence of gnotobiotic fermentation models and the predominance of correlative over causal studies - that must be addressed to translate microbial ecology into predictable fermentation biotechnology. By integrating microbial ecology, fermentation biochemistry, spoilage prevention, and applied biotechnology, this review is intended for researchers in tobacco microbiology and fermentation science, as well as cigar manufacturers, quality-control practitioners, and biotechnologists seeking microbiome-based strategies for quality improvement and risk mitigation.",

Shatavarin IV was isolated and characterised using chromatographic and spectroscopic techniques. Its antidiabetic activity was assessed in STZ-induced diabetic rats by monitoring blood glucose, insulin, glycated haemoglobin, and lipid profile parameters. Treatment with shatavarin IV, particularly at 400\u2009\u03bcg/kg (p.o., b.w.), significantly reduced fasting blood glucose from 265.80 to 119.58\u2009mg/dL, improved insulin levels from 13.99 to 21.69 mIU/mL, and decreased HbA1c from 11.52 to 5.91%. Additionally, it ameliorated diabetes-induced dyslipidemia by lowering total cholesterol, triglycerides, LDL, VLDL, and atherogenic index while increasing HDL. These effects are likely mediated by the steroidal saponin nature of shatavarin IV, which modulates glucose and lipid metabolism. These findings identify shatavarin IV as a key bioactive constituent of A. curillus with antidiabetic and hypolipidemic potential.",

However, how sedimentary organic matter (SOM) and microbial functional differentiation jointly direct arsenic toward thioarsenate formation and methylation remains insufficiently constrained. This study combined sedimentological characterization, X-ray diffraction mineralogical analysis, Fe/As sequential extraction, excitation-emission matrix fluorescence spectroscopy, FT-ICR-MS molecular characterization of SOM, and metagenomic sequencing across three hydrogeochemical zones. Sediments shifted from coarse-grained alluvial deposits in the low-As recharge zone (ALZ) to fine-grained, organic-rich lacustrine sediments in the thioarsenate-enriched zone (HGD) and the methylation zone (SHX), with clay enrichment in HGD and carbonate enrichment in SHX. Along this gradient, ALZ showed open recharge conditions with labile SOM and dynamic redox environments, whereas As in HGD and SHX shifted from surface-bound forms to poorly crystalline and crystalline Fe-associated fractions, alongside SOM evolution toward humified, aromatic, highly unsaturated, and sulfur-containing molecules. The HGD exhibited enrichment of polyphenols and CHOS/CHONS compounds, providing substrates and redox-active ligands for Fe-S-As coupling. Metagenomics revealed zone-specific functional differentiation. The ALZ was dominated by Proteobacteria supporting heterotrophic metabolism, sulfur oxidation, and arsenic resistance. The HGD showed enhanced sat-aprAB-dsrAB pathways and weakened soxABCDXYZ-mediated sulfur oxidation, favoring reduced sulfur accumulation, Fe-As mineral sulfidation, and thioarsenate formation. The SHX displayed enrichment of arsC and arsenic resistance/efflux genes, supporting As(V) reduction and methylated As transformation. These results demonstrate that sediment heterogeneity governs As speciation and migration through coupled SOM evolution and microbial functional reorganization.",

These compounds are directly relevant to human health, and their impact is influenced by structural diversity. The chemical composition of pectins varies according to botanical origin and is shaped by extraction and modification processes. Such structural differences determine both technological functionality and a range of bioactive properties, establishing pectins as potent dietary fibers with systemic health effects. Modified pectins exhibit immunomodulatory and anticancer activities through mechanisms including receptor interactions and modulation of key signaling pathways. In vivo studies further demonstrate their roles in regulating metabolism and in supporting gut barrier integrity. A critical aspect of pectin bioactivity involves promoting symbiotic interactions within the gut microbiota, increasing microbial diversity, and stimulating the production of beneficial metabolites, including short-chain fatty acids. Translational research, including clinical trials, has confirmed practical benefits for gastrointestinal management and metabolic health, and has highlighted the utility of pectins as adjuvants in pharmaceutical and nutritional formulations. This chapter highlights the link between pectins and the intersection of food science, nutrition, and biomedicine, emphasizing their potential as multifunctional ingredients for innovative health strategies.",

The human gut microbiota, with its complex enzymatic potential, converts dietary substrates into a wide range of bioactive molecules, including short-chain fatty acids, vitamins, neuroactive compounds, and polyphenol-derived metabolites that influence host metabolism, immunity, and neurological functions. Advances in microbial genomics, systems biology, and synthetic biology now allow the design of fermentation processes and engineered microbial strains capable of producing specific metabolites with improved bioavailability and tailored health effects. Precision fermentation integrates traditional microbial fermentation with genome editing, metabolic flux optimisation, and AI-assisted pathway design to achieve predictable yields of vitamins, polyphenols, bioactive peptides, and long-chain polyunsaturated fatty acids. These innovations create opportunities to develop functional foods, nutraceuticals, and personalized nutrition strategies that match metabolite profiles to an individual's microbiome composition.

The metabolic syndrome (MetS) z-score provides a continuous benchmark for clustered risk. The single-point insulin sensitivity estimator (SPISE), based on body mass index (BMI) and fasting lipids, may offer a practical alternative where insulin testing is impractical. We aimed to assess the association between SPISE and cardiometabolic burden in children with molecularly confirmed BBS, and to compare its ability to identify MetS against the MetS z-score benchmark and insulin-derived indices. Single-center retrospective pilot study including children/adolescents with genetically confirmed BBS who underwent standardized anthropometry and metabolic profiling (fasting lipids, glucose, insulin; OGTT when available). SPISE-MetS z-score associations were examined using Spearman and adjusted analyses. In adolescents (\u2265\u200910 years), MetS discrimination was evaluated with ROC curves for SPISE, TG/HDL, and homeostatic model assessment for insulin resistance (HOMA-IR), with pairwise DeLong comparisons and Youden-optimal thresholds. Fourteen participants (7 females, 7 males) were evaluated. Median age at last visit was 11.7 years [IQR 7.6-15.5]; BMI SDS was 3.05 [2.47-3.57]. The median MetS z-score was 1.60 [0.90-1.75]. SPISE correlated inversely with the MetS z-score (\u03c1=-0.57, p\u2009=\u20090.021), and adjusted models (age, sex, BMI-SDS) retained significance. Among adolescents (n\u2009=\u200910), SPISE showed the highest AUC for MetS (AUC 0.95; 95% CI 0.82-1.00) versus TG/HDL (AUC 0.81) and HOMA-IR (AUC 0.60); pairwise differences were not statistically significant. Youden-optimal SPISE\u2009\u2264\u20093.34 identified MetS with high sensitivity in adolescents. Confidence intervals were wide, reflecting the small sample size. In this single-center pediatric BBS cohort, SPISE tracked continuous MetS burden and showed numerically stronger discrimination for MetS than insulin-derived indices. These findings highlight the potential utility of SPISE as a feasible tool for cardiometabolic monitoring in syndromic obesity, where laboratory access may be limited. Beyond BBS, SPISE may support early risk stratification and follow-up in rare obesity models of metabolic risk, but multicenter prospective validation remains warranted.",

VL has been implicated in oxidative stress, inflammation, pigmentation disorders, and photoaging, especially in individuals with darker skin phototypes. As conventional sunscreens offer limited protection in the visible spectrum, increasing attention has been directed toward complementary photoprotective strategies, including the use of natural compounds with antioxidant and anti-inflammatory properties. This systematic review aims to evaluate and synthesize the available preclinical and clinical evidence on the photoprotective effects of natural compounds against VL-induced skin damage, emphasizing their mechanisms of action, efficacy, and safety. A comprehensive literature search was performed to identify studies reporting validated objective outcomes, including colorimetric parameters, diffuse reflectance spectroscopy, or clinical grading scales. Eligible studies were included, qualitatively synthesized, and risk of bias was evaluated. Preclinical studies demonstrated that natural compounds mitigated VL-induced oxidative stress, inflammation, and pigmentation-related pathways. Clinical studies showed that formulations containing natural compounds improved VL-induced erythema and pigmentation outcomes. However, considerable heterogeneity was observed in irradiation protocols, outcome measures, and study designs, precluding quantitative meta-analysis. Overall, available evidence supports a protective role for selected natural compounds against VL-induced skin damage, particularly through antioxidant and anti-inflammatory mechanisms, with the strongest clinical evidence focusing on natural sources of polyphenols. Nevertheless, this review highlights the need for standardized phototesting protocols and well-designed clinical trials. Future research should focus on comparative efficacy, long-term safety, and integration of natural compounds into combined photoprotection strategies tailored to different skin phototypes.",

This study integrated GEO dataset mining and network pharmacology to explore the anti-HUA efficacy and mechanism of pomegranate peel polyphenol extract (PPE). In a mouse model of HUA induced by potassium oxonate and 5% fructose water, PPE significantly reduced serum, urinary, and fecal uric acid levels, attenuated the increases in creatinine and blood urea nitrogen, improved estimated glomerular filtration rate, and ameliorated renal pathological damage, inflammation, and xanthine oxidase activity. Integration of GEO-derived HUA-related genes and computational target prediction for PPE identified 44 common targets, and protein-protein interaction network analysis revealed core targets including Akt1. KEGG enrichment highlighted the PI3K-AKT signaling pathway as a key mediator. Western blotting in\u00a0vivo and in\u00a0vitro confirmed that PPE suppressed PI3K-AKT phosphorylation and downregulated the urate reabsorption transporters URAT1 and GLUT9. Furthermore, experiments in UA-induced HK-2 cells demonstrated that ellagic acid, a major bioactive component of PPE, acted through the same pathway. These findings indicate that PPE reduces uric acid levels and protects the kidney via modulation of the PI3K-AKT pathway, providing an integrative data-driven rationale for its potential as a functional food or pharmaceutical agent against HUA.",
"42558291": "ID: 42558291\nTitle: IL-33 promotes efferocytosis by peritoneal macrophages by a mechanism associated with rapid granulocyte IL-13 production.\nAbstract: Resolution of inflammation is an active process that requires efferocytosis, the engulfment of apoptotic cells by macrophages, mediated by receptors such as MerTK. IL-33 is an alarmin that initiates type 2 immune responses, including increased production of IL-13, which promotes MerTK expression. The ability of IL-33 to promote efferocytosis in vivo was examined. Intraperitoneal administration of IL-33 to mice increased local MerTK+ macrophage numbers within 48h. MerTK+ macrophages were not similarly induced by free mitochondria, an alternative cell damage associated signal. Efferocytotic activity was increased rapidly in response to apoptotic thymocytes in IL-33-treated mice. The established inducer of MerTK expression, IL-13, was detected in peritoneal lavage fluid shortly after IL-33 administration. Peritoneal eosinophils expressed the IL-33 receptor and demonstrated both intracellular IL-13 by flow cytometry and significantly increased Il13 transcript expression following IL-33 treatment. In contrast, neither elevated IL-13 expression nor IL-13 protein secretion was observed in peritoneal lymphocyte populations within the first 6 hours after IL-33 administration. Primary cultures of bone marrow-derived mouse mast cells and eosinophils demonstrated IL-13 protein responses to IL-33 administration within 6\u00a0h. Mast cell-deficient Cpa3-Cre; Mcl-1fl/fl mice had significantly reduced IL-13 levels in the peritoneal cavity 3 hours after IL-33 administration when compared with mast cell-containing littermates. In contrast, IL-33-treated eosinophil-deficient \u0394dblGATA mice had similar levels of IL-13 at this time point as wild type controls. These data demonstrate that IL-33 promotes MerTK expression, critical for efferocytosis by macrophages, by a process associated with an early rapid local increase in IL-13 production to which mast cells are a substantial early contributor. These findings contribute to our understanding of clinical situations where elevated soluble IL-33 receptor (sST2) and/or lower mast cell numbers are associated with worse clinical outcome.",

This systematic review evaluates metabolic effects of oat \u03b2-glucan, rice bran, and unripe banana flour in adults, assessing glycaemic, lipid, and mechanistic effects, synthesising their physiological pathways across distinct fibre types (viscosity-driven, phytochemical-mediated, and resistant starch fermentation mechanisms). Following PRISMA 2020 guidelines, PubMed, Scopus, and Web of Science were searched up to June 2025. A total of 602 records were identified, and after removing 146 duplicates, 456 were screened. Forty-four full texts were assessed, and 15 studies were included. Risk of bias was evaluated using RoB 2.0 and Newcastle-Ottawa. Outcomes included glycaemic markers, insulin response, lipid profile, blood pressure, body composition, and mechanistic biomarkers. Studies (n = 15; sample sizes 10-154; durations 3 days-12 weeks) demonstrated heterogeneous dosing and formulations. Oat \u03b2-glucan consistently improved postprandial glucose, insulin AUC, and LDL-C, with modest effects on waist circumference and blood pressure. Rice bran improved blood lipids consistently, while glycaemic effects were mixed. UBF resistant starch was associated with reduction in fasting glucose, HOMA-IR, and body weight, although findings are based on small, short-duration trials. However, variability in study design and limited mechanistic assessments restricted cross-fibre synthesis. The available evidence suggests modest improvements in glycaemic and lipid outcomes. Differences in responsiveness likely reflect variations in fibre structure, viscosity, and fermentability, suggesting complementary physiological pathways. Standardised dosing, longer interventions, and mechanistic biomarkers - including SCFA profiles, incretin response, and bile acid signalling - are needed to clarify inter-individual variability and guide fibre-based interventions.",

Concerns about side effects and long-term therapy restrictions have raised interest in supplementary therapeutic approaches, even if traditional pharmaceutical and surgical procedures are still crucial to the management of CVD. Evidence from published experimental, clinical, and mechanistic investigations that were indexed in PubMed, Scopus, Web of Science, and Google Scholar between 2014 and 2025 is compiled in this review. Through their antioxidant, anti-inflammatory, lipid-lowering, antihypertensive, and endothelial-protective properties, plant-derived phytochemicals such as flavonoids, carotenoids, polyphenols, glucosinolates, and sulfur-containing compounds have considerable cardioprotective potential. Vascular function, oxidative stress, platelet aggregation, insulin sensitivity, and lipid metabolism have all benefited by compounds like quercetin, catechins, curcumin, resveratrol, and lycopene. However, its therapeutic translation is still constrained by issues with bioavailability, dosage uniformity, and clinical validation. Although more extensive clinical research is needed to determine their long-term efficacy and safety, the evidence now available indicates that phytochemicals may be beneficial supplements to traditional cardiovascular treatments.",

Adherence to the Mediterranean diet has been associated with reduced inflammation. However, evidence linking Mediterranean diet to composite inflammatory indices derived from routine blood tests is limited, particularly in individuals seeking weight loss interventions. In this cross-sectional study, 1,738 adults requesting a weight loss dietary program underwent anthropometric assessment, body composition evaluation, and fasting blood sampling. Adherence to the Mediterranean diet was assessed using the 14-item Mediterranean Diet Adherence Screener (MEDAS). Hematologic inflammatory indices, including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), lymphocyte-to-monocyte ratio (LMR), systemic inflammation response index (SIRI), and monocyte-to-HDL ratio (MHR), were calculated. After adjustments for sex, age, BMI, body fat percentage, metabolic syndrome, smoking status, physical activity, education level, and marital status, each 1-point increase in MEDAS score was associated with lower NLR (\u03b2 = -\u20090.065; 95% CI: -\u20090.102, -\u20090.028, p\u2009=\u20090.001), PLR (\u03b2 = -\u20092.660; 95% CI: -\u20094.570, -\u20090.749, p\u2009=\u20090.006), SII (\u03b2 = -\u200921.233; 95% CI: -\u200931.520, -\u200910.947, p\u2009<\u20090.001), SIRI (\u03b2 = -\u20090.046; 95% CI: -\u20090.068, -\u20090.024, p\u2009<\u20090.001), and MHR (\u03b2 = -\u20090.0002; 95% CI: -\u20090.0003, -\u20090.0001, p\u2009=\u20090.003), and with higher LMR (\u03b2\u2009=\u20090.078; 95% CI: 0.038, 0.117, p\u2009<\u20090.001), all reflecting a shift toward a more favorable inflammatory profile. Greater adherence to the Mediterranean diet was associated with a more favorable inflammatory profile. These results support the role of the Mediterranean diet in modulating low-grade systemic inflammation in clinical nutrition settings.",

The biodegradability behavior of textile products made from virgin materials has been extensively studied. Although it is known that recycled textile products provide significant environmental benefits, whether these materials have created a change in terms of biodegradability is still a subject of interest. Biodegradation of woven fabrics made of virgin cotton (CO)/recycled cotton (r-CO) fibers, recycled polyester (r-PET)/r-CO fiber blends, 100% r-PET fibers and their virgin counterparts, (100% CO and 100% virgin polyester (PET)) fibers were investigated in soil for 1-, 4- and 7- month soil burial periods. Biodegradability properties were determined by weight loss analysis, Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR) analysis and microorganism and organic carbon analyses. According to the results of the study, fabrics made from 100% CO and CO/r-CO fibers exhibited degradation rate of 93-95% after 1\u00a0month and complete degradation after 4\u00a0months. While biodegradation occurred depending on the r-CO ratio in the structure for fabrics produced from r-PET/r-CO fibers, no degradation was observed for 100% PET and 100% r-PET fabrics after 1, 4, and 7\u00a0months. It was concluded that recycled fibers in the structure exhibited similar degradation behavior to their virgin counterparts. Furthermore, SEM and FTIR analyses confirmed the weight loss results. The results of total bacteria, yeast-mold, and organic carbon analyses showed different trends depending on the soil burial periods and biodegradability of the samples.",

Probiotics and dietary fibers have diverse bioactivities but are limited by poor stability and low bioavailability. Herein, a novel microcapsule system co-loading Ganoderma lucidum dietary fiber (GLDF) and Lactobacillus fermentum CECT5716 was constructed using whey protein (WP) and xanthan gum (XG) via hybrid spray drying-complex coacervation. Optimal WP-XG interaction (driven by electrostatic forces and hydrogen bonds) was achieved at pH\u00a03.75 and 5:1 mass ratio; microcapsules with 1:1 wall-to-core ratio showed the best performance, with 72.3% post-encapsulation probiotic viability and enhanced stability under simulated gastrointestinal conditions and storage. Animal experiments confirmed that the microcapsules effectively alleviated loperamide (LOP)-induced constipation in mice, associated with regulating gut microbiota, promoting short-chain fatty acids (SCFAs) production, inhibiting colonic inflammation, repairing intestinal tight junctions, and downregulating aquaporins. In conclusion, the microcapsules prepared in this study provide a feasible strategy for the efficient co-delivery of probiotics and dietary fibers, and the developed composite functional ingredient holds great application potential in the field of constipation prevention and treatment.",

Despite their favorable nutritional composition, they also naturally contain antinutritional factors such as phytic acid, that limit the absorption of micronutrients. This, coupled with the lower bioavailability of proteins as compared with meat, diminishes the biological and economic value of legumes. However, recent studies have shed a light on the power of fermentation to improve the protein profile of pulse and neutralize antinutritional compounds. In this review, we explore the benefits of legumes fermentation in depth, focusing on the role of microorganisms in enhancing the nutritional and sensory enhancement of legumes. Furthermore, we describe the properties and the microorganisms involved in the production of several craft-based fermented legumes typically consumed by non-Westernized populations, particularly delving into their effects on the gut microbiome and on the human health.",

Lentils are abundant in these compounds, yet comparative studies across varieties and intestinal cells effects remain limited. This study evaluated the nutritional composition, phenolic profile, antioxidant activity, and \u03b1-glucosidase inhibition of four lentil types in raw and cooked forms. L01 had the highest bioactive potential and was the only one selected for further evaluation in Caco-2 cells under basal and IL-1\u03b2-stimulated conditions. Cooking altered composition, leading to higher protein, fiber, and carbohydrates, reducing tannins, and maintaining high phytic acid in some varieties. L01 consistently showed the highest phenolic content, antioxidant activity, and enzyme inhibition. Its phenolic profile was dominated by kaempferol derivatives, (epi)catechin, and procyanidins, with cooking increasing monomeric catechins but reducing procyanidin oligomers. At noncytotoxic levels, L01 extracts reduced IL-6/8 secretion in stimulated cells, with stronger effects from raw extracts. Additionally, they decreased expression of inflammatory markers (IL-6/8/1\u03b2) while increasing expression of metabolic regulation- and barrier-related genes (Peroxisome proliferator-activated receptor-\u03b3, Sirtuin 1, Occludin, and Cadherin-1).

These findings highlight compositional differences beyond tegument color and support further investigation of phenolic-rich lentils as potential functional food ingredients targeting gut and metabolic health.",
"42563498": "ID: 42563498\nTitle: From Gut to Heart: The Emerging Role of Dietary Fermentable Fiber in Heart Failure with Preserved Ejection Fraction.\nAbstract: Heart failure with preserved ejection fraction (HFpEF) is a multisystemic syndrome that accounts for more than half of all heart failure cases and causes a substantial burden of morbidity and mortality. In contrast to heart failure with reduced ejection fraction (HFrEF), few disease-modifying therapies exist for HFpEF, reflecting differences in pathophysiology. Low fermentable fiber (FF) intake, gut dysbiosis, and depletion of short-chain fatty acids (SCFAs), microbial metabolites central to immune, metabolic, and vascular homeostasis, are increasingly linked to the pathophysiology of HFpEF. Here, we synthesize preclinical and clinical evidence on FF and SCFAs and evaluate their therapeutic relevance to HFpEF. Preclinical studies demonstrate that FF supplementation or direct SCFA administration improves cardiometabolic function and attenuates cardiac remodeling through SCFA receptor signaling, enhanced nitric oxide bioavailability, reduced inflammation, and metabolic support of the energy-starved failing heart. Supporting the translational relevance of these findings, a systematic review of 27 human randomized controlled trials showed that FF interventions exert microbiome-mediated effects, enriching SCFA-producing taxa and augmenting fecal and circulating SCFA levels, while improving insulin sensitivity and reducing abdominal adiposity and LDL cholesterol. Direct SCFA supplementation increases SCFA availability and provides modest metabolic benefits, including reduced adiposity and liver fat. However, its effects are inconsistent. Collectively, these findings provide a mechanistic and translational rationale for FF-based interventions in HFpEF. To date, no clinical trials have evaluated the effects of FF on HFpEF-specific outcomes. Clinical studies are therefore needed to determine whether increasing FF intake can improve symptoms, cardiac function, and disease progression in HFpEF.",

To determine the association between admission lipid profiles and adverse clinical outcomes in hospitalised COVID-19 patients within a resource-constrained setting, in a predominantly black African population. This retrospective observational study was conducted at Charlotte Maxeke Johannesburg Academic Hospital between 6 March and 31 August 2020. Adults aged \u226518 years with confirmed SARS-CoV-2 infection who had admission lipid profiles were included. The association between lipid parameters and adverse clinical outcomes, including intensive care unit (ICU) admission, mechanical ventilation, and in-hospital mortality, were determined by multivariable logistic regression analysis. Correlation analyses examined associations between lipids and inflammatory markers. Among 305 patients (mean (standard deviation) age 53 (13.8) years; 77% black ethnicity), non-survivors had significantly lower low-density lipoprotein cholesterol (LDL-C) and total cholesterol (TC), and higher fasting plasma glucose and inflammatory markers. Both LDL-C and TC were inversely correlated with procalcitonin (\u03c1=-0.44, 95% confidence interval (CI) -0.65 - -0.23, p=0.001; (\u03c1=-0.28, CI-0.52 - -0.05), p=0.03, respectively). Triglyceride (TG) levels were higher in ICU patients (p=0.01), and significantly correlated with an increasing white cell count (\u03c1=0.31, CI 0.09 - 0.53, p=0.01), neutrophil-to-lymphocyte ratio (\u03c1=0.27, CI 0.01 - 0.54, p=0.04) and fasting plasma glucose (\u03c1=0.39, CI 0.14 - 0.64, p=0.03), but were not independently predictive of mortality. High-density lipoprotein cholesterol was lower in ICU-admitted patients and inversely correlated with ferritin, but it was also not significantly associated with mortality. Lower LDL-C was an independent predictor of ICU admission (odds ratio (OR) 0.69, CI 0.50 - 0.96, p=0.03 ), mechanical ventilation (OR 0.55, CI 0.35 - 0.86, p=0.009 ) and mortality (OR 0.66, CI 0.48 - 0.91, p=0.01), with an LDL-C <2.2 mmol/L associated with increased mortality(area under curve 0.62, CI 0.55 - 0.69), as shown in receiver operating characteristic analysis. Non-survivors had significantly higher inflammatory markers compared with survivors, and low LDL-C and TC were independently associated with adverse outcomes. LDL-C also predicted ICU admission, mechanical ventilation and mortality, highlighting the link between lipid metabolism and immune response. These findings emphasise the need for further prospective studies to evaluate the utility of these markers as accessible prognostic tools in low- and middle-income countries.",
"42563722": "ID: 42563722\nTitle: Factors influencing metabolic syndrome in adult workers: an analysis of data from the 2022 Korea National Health and Nutrition Examination Survey.\nAbstract: This study analyzed the prevalence of metabolic syndrome and influencing factors among adult workers aged 19 to 64. Data from the ninth Korea National Health and Nutrition Examination Survey conducted in 2022 were utilized. The sample comprised 685 individuals who had measurements of fasting glucose, triglycerides, high-density lipoprotein cholesterol, blood pressure, and waist circumference, which are necessary to diagnose metabolic syndrome. Data analysis was performed using SPSS 26.0, and complex sample logistic regression was conducted to identify factors influencing metabolic syndrome. Among the participants, 34.3% were diagnosed with metabolic syndrome. Significant differences were observed in sex, age, region, marital status, regular worker, and physical activity between participants with and without metabolic syndrome (p < .05). Factors influencing the prevalence of metabolic syndrome included sex, age (with the 19~29 age group showing a significantly lower risk), physical activity, smoking, and perceived stress levels (p < .05). To prevent metabolic syndrome in adult workers, it is essential to promote physical activity, discourage smoking, and encourage effective stress management.",
"42563800": "ID: 42563800\nTitle: [Association between metabolic syndrome and autonomic nervous system activity in middle-aged menopausal women in South Korea: a cross-sectional study].\nAbstract: This study aimed to investigate the association between metabolic syndrome and autonomic nervous system activity in middle-aged postmenopausal women. In addition, it explored the clinical applicability of heart rate variability (HRV) as a physiological marker for the early diagnosis and management of metabolic disorders. This study was conducted as a secondary data analysis using health examination data. The dataset included 276 postmenopausal women aged 50 to 65 years. Autonomic nervous system activity was evaluated using HRV indices, including standard deviation of the normal-to-normal interval (SDNN), total power (TP), low frequency (LF), and high frequency (HF). Statistical analyses were performed using the t-test, chi-square test, and Pearson correlation analysis with SPSS version 26.0. The prevalence of metabolic syndrome among the participants was 21.4%. The LF index was significantly lower in the metabolic syndrome group compared with the normal group (t = 2.74, p = .007). Additionally, fasting blood glucose showed significant negative correlations with SDNN (r = -.16, p = .010), TP (r = -.21, p < .001), LF (r = -.17, p = .004), and HF (r = -.18, p = .003). A reduction in HRV, particularly in LF, may serve as an indicator of metabolic syndrome in postmenopausal women. Because autonomic dysfunction can potentially be improved through nursing interventions, the use of HRV-based monitoring and personalized nursing strategies should be considered in clinical practice to help prevent the onset of metabolic syndrome in postmenopausal women.",
"42564155": "ID: 42564155\nTitle: Evening chronotype is associated with higher circulating pyruvate levels in adults.\nAbstract: Chronotype reflects interindividual differences in the circadian timing system. Animal studies suggest reduced mitochondrial oxidative metabolism and tricarboxylic acid (TCA) cycle activity in individuals with an evening chronotype; however, human evidence linking chronotype to mitochondrial metabolic alterations remains limited. This cross-sectional study examined whether chronotype is associated with differences in circulating TCA-related metabolites, including pyruvate, lactate, and citrate. A total of 272 adults from the 2022 Gangwon Obesity and Metabolic Syndrome Cohort were classified as having morning (\u226518), intermediate (12-17), or evening (\u226411) chronotype using the reduced Morningness-Eveningness Questionnaire. Fasting serum concentrations of pyruvate, lactate, and citrate were measured. Associations were examined using general linear models adjusted for fasting status; demographic, socioeconomic, and lifestyle factors; as well as body mass index. Sensitivity analyses excluded participants taking metabolic disease-related medications. Major clinical and metabolic indicators did not differ across chronotypes. Serum pyruvate concentrations were higher in the evening chronotype group than in the morning chronotype group across all adjusted models (p\u202f<\u202f0.048), whereas lactate and citrate concentrations did not differ. These findings remained consistent in sensitivity analyses excluding participants with metabolic diseases (p\u202f=\u202f0.006-0.010). Across analyses that included and excluded participants using metabolic disease-related medications, evening chronotype was consistently associated with higher circulating pyruvate concentrations, a key metabolic branch point downstream of glycolysis. These findings suggest chronotype-related differences in pyruvate metabolism, with potential implications for metabolic regulation.",
"42564199": "ID: 42564199\nTitle: Euonymus alatus in diabetes: a review of phytochemistry, pharmacokinetics, and anti-diabetic mechanisms.\nAbstract: Euonymus alatus: (EA), a traditional Chinese botanical drug documented in the Shennong Ben Cao Jing, has been investigated for its potential anti-diabetic effects. This review systematically examines the phytochemistry, pharmacokinetics, and anti-diabetic mechanisms of this botanical drug. Over 230 metabolites, including flavonoids, triterpenoids, and lignans, have been identified from EA. Pharmacokinetic studies remain limited; computational predictions suggest that some metabolites may exhibit oral bioavailability, but classical pharmacokinetic parameters have not been experimentally determined for any EA metabolite. Mechanistic studies demonstrate that EA exerts anti-diabetic effects through multiple experimentally validated pathways: (i) inhibiting alpha-glucosidase activity to delay intestinal glucose absorption; (ii) activating the peroxisome proliferator-activated receptor gamma and phosphatidylinositol 3-kinase/protein kinase B signaling pathways to ameliorate insulin resistance; (iii) modulating gut microbiota composition and increasing short-chain fatty acid production; (iv) suppressing the advanced glycation end products-receptor for advanced glycation end products axis along with the nuclear factor kappa B and mitogen-activated protein kinase inflammatory pathways to alleviate oxidative stress and inflammatory responses; and (v) regulating diacylglycerol acyltransferase activity to improve lipid metabolism. Preclinical studies indicate that EA reduces blood glucose and improves markers of diabetic nephropathy and retinopathy. Clinical studies of EA-containing formulations report reductions in fasting blood glucose and urinary protein. However, the clinical evidence remains limited by small sample sizes, lack of rigorous controls, and multi-botanical drug compositions that preclude attribution of effects to individual components. This review provides a critical synthesis of current evidence and identifies priorities for future investigation.",
"42564435": "ID: 42564435\nTitle: Germinated Brown Rice: A Natural Source of Bioactive Compounds Boosting Human Health.\nAbstract: Germinated brown rice (GBR) has gained considerable attention as a functional food due to both nutritional and bioactive profiles as well as health-promoting properties. The present narrative review is aimed at summarizing and discussing available research on GBR, focusing on bioactive composition and potential to support human well-being. Based on available data, the germination process of brown rice enhances the bioavailability of key bioactive compounds, including polyphenols, \u03b3-aminobutyric acid, \u03b3-oryzanol, vitamins, and dietary fibers. Additionally, a substantial body of evidence supports the ability of GBR to exert beneficial physiological effects on the host, such as modulation of lipid and glucose metabolism, antioxidant and anti-inflammatory activities, and positive influences on gut microbiota composition. The use of GBR in formulating functional foods and nutraceutical supplements further highlights its versatility as a promising strategy in supporting human well-being."
