A simple specific method for the detection of glycogen concentration in various tissues without disintegration of its structure is described. The method includes staining of glycogen molecules with iodine. The results of determination do not depend on the presence of polysaccharides because they are not stained with iodine but release reducing sugars during hydrolysis. Glycogen content is calculated from the calibration curve.

This study investigated the effects of bisphenol A (BPA) and the involvement of nuclear estrogen receptors (ESR) on testicular energy metabolism and spermatogenesis in zebrafish. Testes were incubated with DMSO, 10 pM or 10μM BPA for 6 or 72h, with some samples pre-incubated with the ESRα/β antagonist ICI 182,780. Gene and protein expressions were analyzed using real-time PCR and Western blot, respectively.

This study evaluated the effects of a glyphosate-based herbicide on the oxidative balance, energy metabolism, and body condition indices in tadpoles of Boana faber. Anuran spawns were collected, and after hatching and reaching Gosner stage 25, they were acclimated and exposed (168hours) to concentrations of glyphosate (G1: 65, G2: 260, and G3: 520µg/L). The body condition markers revealed a significant decrease in all these biomarkers in G2 and G3.

Environmental pH is an important parameter that impacts the growth, reproduction, and carbohydrate metabolism of Aureobasidium spp.. This study identifies the ApGph1 gene (encoded with Glycogen Phosphatase) reflecting significant carbohydrate metabolism difference through transcriptome analysis of Aureobasidium Pullulans YQ65 cultured under different pH.

Ingestion of fructose and galactose may result in elevated lactate concentrations in patients with glycogen storage disease type 1 (GSD1). In this randomized cross-over pilot study, 7 patients with GSD 1a (6) and GSD1b (1) orally consumed a common-size fructose and galactose from either 200 mL of skimmed milk, 200 mL juice or 200 mL water. This was given after a night with their usual dietary treatment using either cornstarch, glycosade or continuous feed.

Background: Sepsis-induced cardiomyopathy (SICM) often occurs in the acute phase of sepsis and is associated with increased mortality due to cardiac dysfunction. The pathogenesis remains poorly understood, and no specific treatments are available. Although SICM is considered reversible, emerging evidence suggests potential long-term sequelae.
