Second‐trimester multimetabolite panel for early preeclampsia rule‐out

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective We aimed to establish a high‐sensitivity, multimetabolite rule‐out model for the development of preeclampsia (PE), prioritizing minimizing false negatives to exclude low‐risk individuals from intensive surveillance confidently. Methods In this prospective, nested case–control study, maternal serum samples were collected between 20+0 ...

Ginseng polysaccharides prevent mastitis through Lactobacillus murinus‐derived deoxycholic acid and TGR5 signaling

iMetaOmics, EarlyView.
Prebiotic Ginseng polysaccharides (GP) alleviate mastitis through selective enrichment of gut L. murinus, which elevates its anti‐inflammatory metabolite deoxycholic acid (DCA). Circulating DCA engages mammary epithelial TGR5 receptors, triggering the cAMP–PKA pathway to suppress NF‐κB/NLRP3‐mediated inflammation.

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 ...

Health Biomarkers of Pesticide Exposure in Rural Populations of Santa Fe, Argentina: Oxidative Stress and Genotoxicity

Journal of Applied Toxicology, EarlyView.
ABSTRACT The present study aimed to quantify pesticide residues in environmental matrices and plasma and to evaluate their potential effects on oxidative stress and DNA damage in rural populations of Santa Fe province. Soil and rainwater samples were collected, and biological samples and semistructured surveys were obtained from volunteers in three ...
