Possibilities of the use of fast scan voltammetry in simultaneous determination of purines at carbon fiber ultramicroelectrodes

Journal of the Brazilian Chemical Society, 2000
Hypoxanthine, xanthine and uric acid are purines present in extracellular fluids that can be used as metabolic markers, in evaluation of meat conservation and other applications. Voltammetric studies were performed in order to investigate the possibility

Application of Liquid Chromatography Coupled to Mass Spectrometry for Direct Estimation of the Total Levels of Adenosine and Its Catabolites in Human Blood

Pharmaceuticals
Adenosine is a multifunctional nucleoside with several roles across various levels in organisms. Beyond its intracellular involvement in cellular metabolism, extracellular adenosine potently influences both physiological and pathological processes.

Ruminococcus gnavus in the gut: driver, contributor, or innocent bystander in steatotic liver disease?

The FEBS Journal, Volume 292, Issue 6, Page 1252-1264, March 2025.
Ruminococcus gnavus (R. gnavus) can degrade mucin, modify bile acids, and secrete metabolites into circulation via the portal vein to the liver for further processing and subsequent systemic circulation. R. gnavus is associated with metabolic syndrome and inflammatory bowel disease severity. It is suspected that R.

Stress exposure in the mdx mouse model of Duchenne muscular dystrophy provokes a widespread metabolic response

The FEBS Journal, EarlyView.
A targeted mass spectrometry‐based metabolomics assay was conducted to identify the impact of stress exposure on the regulation of biological stress pathways in the mdx mouse model of Duchenne muscular dystrophy. We demonstrated a broad shift in the circulating stress‐relevant plasma metabolome associated with stressful scruff handling that was ...

Phosphoproteomic Reveals That Phosphoglycerate Kinase 2 Suppresses Hypoxanthine Accumulation in Broiler

Food Frontiers
Recent studies have found that the amount and proportion of meat flavor–related metabolites differ among different parts of muscle, which is partly attributed to their diverse myofiber type composition.

Achilles tenocytes from diabetic and non diabetic donors exposed to hyperglycemia respond differentially to inflammatory stimuli and stretch

Journal of Anatomy, EarlyView.
Scheme depicting the experimental set up of the study. Achilles tendons and tenocytes were isolated from heterozygous (fa/+, non diabetic: non DMT2) and homozygous (fa/fa, diabetic: DMT2) Zucker Diabetic Fatty (ZDF) rats. Tendon degeneration, collagen type 1 alpha 1 chain (COL1A1) and alpha smooth muscle actin (αSMA) expression was determined in rat ...

Age‐dependent reduction in voltage‐gated inward sodium current and Scn8a gene expression in murine stellate ganglia

Annals of the New York Academy of Sciences, Volume 1545, Issue 1, Page 91-104, March 2025.
An investigation into the electrophysiological properties of murine ventricular myocardium and stellate ganglia was conducted using the loose patch clamp technique at two distinct age points to assess aging‐mediated alterations in ionic currents. The voltage‐gated inward sodium current, quantified as maximum sodium current (INa(Max)), was reduced with ...
