Microbial keystone taxa and metabolic signatures in centenarians regulate intestinal homeostasis during aging

iMeta, EarlyView.
Clostridium scindens and its metabolite indole‐3‐acetic acid (IAA) are identified as a keystone taxon and metabolic signature in centenarians. Clostridium scindens enhances microbial network stability and produces IAA via its own amidase (AMIE) and aldehyde dehydrogenase (ALDH), thus promoting intestinal homeostasis by activating the aryl hydrocarbon ...

Multi‐omics biomarkers for intestinal infection and inflammation in inflammatory bowel disease: Current evidence, translational challenges, and diagnostic opportunities

Interdisciplinary Medicine, EarlyView.
Prospective multi‐site cohorts, multi‐omics profiling, and computational analysis may help identify biomarker patterns across clinical settings in IBD and superimposed infections. With further mechanistic and clinical validation, these signals could support the development of practical multi‐analyte tools for more precise diagnosis and management ...

Miniaturized Droplet‐Based Adaptation of the Ames Test for High‐Throughput Mutagenicity Assessment

Journal of Applied Toxicology, EarlyView.
ABSTRACT This work presents the first demonstration of a tube‐based droplet microfluidic implementation of the Ames test, bridging single‐droplet resolution with regulatory genotoxicity testing. The Ames test is a cornerstone assay for detecting mutagenicity, but conventional plate‐ and well‐based formats suffer from high reagent consumption, low ...

Immunomodulation of the Prostate Tumor Microenvironment Following Inorganic Arsenic Exposure

Journal of Applied Toxicology, EarlyView.
ABSTRACT The tumor microenvironment (TME) influences prostate cancer (PCa) progression through stromal and immune interactions. Adipose‐derived mesenchymal stromal cells (ASCs) modulate immune tone, while inorganic arsenic (iAs), a widespread toxicant, is linked to immune suppression and carcinogenesis.

Beyond Tradition: An Integrated Toxicological, Ecological, and Public Health Perspective on Aristolochic Acids

Journal of Applied Toxicology, EarlyView.
ABSTRACT Aristolochia species have long been used in traditional medicine for their presumed anti‐inflammatory, analgesic and antimicrobial properties. However, extensive toxicological and epidemiological evidence now demonstrates that these plants contain aristolochic acids (AAs) I and II, highly potent nephrotoxic, genotoxic, and carcinogenic ...

Colonic Barrier Dysfunction and Inflammation Induced by Nano‐/Micro‐Plastics Fibers in Mice via the FAK/NF‐κB/iNOS and TLR4/NF‐κB/iNOS Pathways

Journal of Applied Toxicology, EarlyView.
ABSTRACT As emerging environmental contaminants, nano‐ and micro‐plastics (NMPs) have drawn increasing research attention due to potential hazards to organisms. Particle shape is a key factor influencing the toxic effects of NMPs, and NMPs of different shapes cause varying degrees of tissue damage. We investigated the specific mechanisms of polystyrene
