UNLABELLED 3T3-L1 adipocytes develop insulin-resistant glucose transport upon preincubation with high glucose or glucosamine, provided insulin (0.6 nM) is present during preincubation. Insulin receptor substrate-1 (IRS-1)-associated phosphatidylinositol (PI) 3-kinase activity is unaffected (30). Total cellular IRS-1, PI 3-kinase, or Akt concentrations were unchanged. Akt activation in subcellul...

Glucose, as the major energy source in cellular metabolism, plays an important role in the natural growth of cells. Herein, a simple, rapid and low-cost method for the glucose determination by utilizing glucose oxidase and CdTe/thioglycolic acid (TGA) quantum dots (QDs) on a thin layer chromatography (TLC) plate has been described. The detection was based on the combination of the glucose enzym...

BACKGROUND/AIMS High glucose-induced oxidative damage to endothelial cells plays a central role in the pathogenesis of diabetic vascular complications. This study was undertaken to explore the role of periostin in high glucose-induced endothelial cell apoptosis and associated molecular mechanisms. METHODS Human umbilical vein endothelial cells (HUVECs) were exposed to high glucose (33.3 mmol/...

Objective(s):The neuroprotective effect offruit aqueous extract of Ziziphus jujuba Lam on glucose-induced neurotoxicity in PC12 cells as an appropriate in vitro model of diabetic neuropathy was investigated. Materials and Methods: Cell viability was determined by the MTT assay. Cellular reactive oxygen species (ROS) generation was measured by DCFH-DA analysis. Cleaved caspase-3, a biochemical p...

Glucose oxidase is an important enzyme hydrolyzing for its hydrolyzing activity on glucos. It possesses and has a wide board of applications in different industries such as bakery, pharmaceutical, plant pathology and biosensors. In this study, yeast (Saccharomyces cerevisiae) was transformed successfully by the glucose oxidase gene (gox) obtained from Penicillium funicolusum. The secreted gluco...

Peroxisome proliferator-activated receptor-gamma (PPARgamma) are ligand-activated transcription factors that regulate cell growth, inflammation, lipid metabolism, and insulin sensitivity. We recently demonstrated that PPARgamma agonists limit high glucose-induced inflammation in a model of proximal tubular cells (PTC; Panchapakesan U, Pollock CA, and Chen XM. Am J Physiol Renal Physiol 287: F52...

BACKGROUND High blood glucose level is frequently encountered in acute coronary syndrome. We investigated the effects of high blood glucose measured on arrival on hospitalization adverse events in acute coronary syndrome. Our study patients were Javanese in ethnicity, which constitute half of population in Indonesia. We hypothesized that elevated blood glucose has detrimental effects on hospita...

objective(s) the purpose of the present study was to evaluate the effect of ramadan fasting and weight-lifting training on plasma volume, glucose, and lipids profile of male weight-lifter. materials and methods forty male weight-lifters were recruited and divided into 4 groups (n=10 each) and as the following groups: control (c), fasting (f), training (t) and fasting-training (f-t). the t and f...
