چکیده

We present the synthesis and characterisation of naphthalimide-flavin redox sensor 1 (NpFR1), a novel flavin molecule that is almost non-fluorescent in reduced form, but oxidation gives rise to a 125-fold increase in fluorescence. Confocal microscopy experiments confirm that is sensitive to redox changes within living cells.

Increased glucose uptake promotes oxidative stress and PKC-delta activation in adipocytes of obese, insulin-resistant mice.

Increased oxidative stress is believed to be one of the mechanisms responsible for hyperglycemia-induced tissue damage and diabetic complications. In these studies, we undertook to characterize glucose uptake and oxidative stress in adipocytes of type 2 diabetic animals and to determine whether these promote the activation of PKC-delta. The adipocytes used were isolated either from C57Bl/6J mic...

Oxidative stress as pathogenesis of cardiovascular risk associated with metabolic syndrome.

Metabolic syndrome (MetS) is characterized by accumulation of visceral fat associated with the clustering of metabolic and pathophysiological cardiovascular risk factors: impaired glucose tolerance, dyslipidemia, and hypertension. Although the definition of MetS is different among countries, visceral obesity is an indispensable component of MetS. A growing body of evidence suggests that increas...

Effect of maternal variable stress on oxidative status and glucose metabolism in pubertal male rats

Introduction: Metabolic disorders are affected by negative stress experiences in the early stages of life. Accordingly, in this study, the effects of stress during pregnancy on oxidative status and glucose homeostasis in pubertal male Wistar rats were investigated. Materials and Methods: After pregnancy, female rats (200±30 g) were divided into 2 groups (6 rats per group) of stress and non-stre...

Protective Effect of Quercetin on Oxidative Stress in Glucose-6-Phosphate Dehydrogenase-Deficient Erythrocytes in Vitro

Glucose-6-phosphate dehydrogenase (G6PD) deficient subjects are vulnerable to oxidative stress. Quercetin, a flavonoids, has been employed as a potent oxygen-free radical scavenger in order to assess the protective effects of quercetin against H2O2-induced oxidative damage in G6PD-deficient and normal human erythrocytes. Erythrocytes of G6PD-deficient (n = 10) and normal (n = 10) subjects were ...

Lysosomal Oxidative Stress Cytotoxicity Induced by Dacarbazine and It’s Pyridine Derivative in Hepatocytes

     Dacarbazine (DTIC) is a synthetic chemical antitumor agent which is used to treat malignant melanoma and Hodgkin’s disease. DTIC is a prodrug which is converted to an active form undergoing demethylation by liver enzymes. The active form prevents the progress of disease via alkylation of DNA strand. In the structure of this drug, the imidazole ring, a triazen chain and carboxamide group ex...
