Bacteroides intestinalis AM-1 rewires glutathione and bile acid metabolism to restore mitochondrial homeostasis and ameliorate necro-apoptosis in acute liver failure

This study demonstrates that the probiotic *Bacteroides intestinalis* AM-1 ameliorates acute liver failure by rewiring glutathione and bile acid metabolism to restore mitochondrial homeostasis and suppress necro-apoptosis, thereby significantly reducing liver injury and mortality.

Mitochondrial Macro-Haplogroup U and Multiple Sclerosis Risk in Arab and Near Eastern Populations: A Pedigree-Anchored Systematic Review and Meta-Analysis

This pedigree-anchored systematic review and meta-analysis demonstrates a robust, directionally consistent association between mitochondrial macro-haplogroup U and Multiple Sclerosis risk across Arab, Iranian, and European populations, yielding a pooled odds ratio of 1.91 despite the limited power of the initial Arab discovery cohort.

Differential placental immune mediators in pregnant women with preeclampsia infected or not with SARS-CoV-2

This study investigates the differential placental immune mediators in pregnant women with preeclampsia, with or without SARS-CoV-2 infection, revealing that specific alterations in immune molecule expression at the maternal-fetal interface may explain why preeclamptic women infected with COVID-19 exhibit a less severe clinical presentation compared to those with COVID-19 alone.

TRIM36 Catalyzes K63-Linked Ubiquitination of TAK1 to Drive Septic Inflammation

This study identifies TRIM36 as a critical positive regulator of septic inflammation that drives TLR4 signaling by catalyzing K63-linked ubiquitination of TAK1, thereby promoting NF-κB activation and cytokine production, which suggests its potential as a therapeutic target for sepsis.

Technical replicates and multiple sequencing approaches reveal weak and inconsistent microbiome signals in tumour and blood samples

This study demonstrates that microbiome signals in low-biomass lung cancer tumor, adjacent tissue, and blood samples are weak, inconsistent, and indistinguishable from contamination, highlighting the critical need for rigorous validation methods like technical replicates and absolute quantification to ensure data reliability.

The Influence of 5-HT2 Receptors on Multimodal Sensorimotor Gating and Hallucination-Like Behavior in Hemiparkinsonian Rats

This study demonstrates that hemiparkinsonian rats exhibit impaired multimodal sensorimotor gating and heightened sensitivity to 5-HT2 receptor-mediated hallucination-like behaviors, suggesting that upregulated 5-HT2 receptors contribute significantly to psychosis-associated symptoms in Parkinson's disease.

Alpha and beta diversity of macroinvertebrate community in relation to river freezing: a case study in the mountainous stream system of north China

This study demonstrates that river freezing in a North Chinese mountain stream significantly alters environmental conditions and macroinvertebrate community structure by shifting diversity patterns from being jointly shaped by water chemistry and spatial distance to being dominated by specific abiotic filters and dispersal limitation, respectively.

Low flow enhances pigmentation and lipid reserves but reduces survival in newly settled Acropora digitifera corals

While low water flow enhances pigmentation and lipid reserves in newly settled *Acropora digitifera* corals, it significantly increases early mortality risk compared to moderate and high flow regimes, demonstrating that optimal conditions for physiological development do not necessarily maximize survival.
