Proteomic analysis of the zone of degeneration at the mitosis–meiosis transition stage in wild‐caught male catshark (Scyliorhinus canicula), correlated with an unusually high‐water temperature in the English Channel

Journal of Fish Biology, EarlyView.
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...

A gas-liquid solid phase peptide and protein sequenator [PDF]

, 1981
A new miniaturized protein and peptide sequenator has been constructed which uses gas phase reagents at the coupling and cleavage steps of the Edman degradation. The sample is embedded in a matrix of Polybrene dried onto a porous glass fiber disc located

Choline Metabolism to the Proatherogenic Metabolite Trimethylamine Occurs Primarily in the Distal Colon Microbiome In Vitro

Metabolites
Background/Objectives: Gut microbial metabolism of choline and related quaternary amines to trimethylamine (TMA) is the first step in the production of trimethylamine N-oxide (TMAO), a circulating metabolite that contributes to the development of ...

Bacterial Extracellular Vesicles in the Pathogenesis and Treatment of Liver Diseases

Journal of Gastroenterology and Hepatology, EarlyView.
Liver diseases are a major global health challenge, with current treatments inadequate. This review highlights the role of bacterial extracellular vesicles in liver inflammation, fibrosis, and metabolism. We also explore these from commensals and probiotics, their protective effects, and discuss research challenges and future therapeutic potential ...

When chemistry meets taxonomy: Studying glycolipidic chemomarkers in pelagic Sargassum spp. (Phaeophyceae) using molecular networking

Journal of Phycology, EarlyView.
Abstract To chemically differentiate the three pelagic Sargassum morphotypes co‐occurring in floating rafts and drifting across the Atlantic Ocean before stranding on West African, Caribbean, and Atlantic Mexican coastlines, we conducted an investigation of their metabolomic profiles.
