background: it is well known that the development of brain oxidative stress is one of the most serious complications of arterial hypertension that evokes brain tissue damage. the aim of this study was to examine the effects of atorvastatin treatment (20 mg/kg/day), as an antioxidant, to prevent the brain tissue oxidative stress in the hypertensive (htn) rats. methods: experiments were performed...

The effect of regucalcin, a regulatory protein in the intracellular signaling process, on superoxide dismutase (SOD) activity in the cytosol of rat liver was investigated. The presence of zinc sulfate (10(-6) or 10(-5) m) or cupric sulfate (10(-6) m) in the enzyme reaction mixture caused a significant increase in SOD activity, indicating that Cu/Zn-SOD may be present in the liver cytosol. SOD a...

tobacco smoke contains numerous compounds, many ‎of which are oxidants and capable of producing free radical and enhancing ‎the oxidative stress. the aim of this study was to investigate the effect of cigarette smoking on the erythrocyte antioxidative enzyme activities and the plasma ‎concentration of their cofactors. ‎sixty eight healthy men were enrolled, 32 of whom had never smoked and 36 ha...

GST-TAT-SOD, a cell-permeable bifunctional antioxidant enzyme, is a potential selective radioprotector. This study aimed to investigate the cytoprotective activity of GST-TAT-SOD against cisplatin-induced damage. The current study showed that cisplatin induced the formation of reactive oxygen species in normal L-02 cells. GST-TAT-SOD (2000 U/mL) executed its antioxidant role by directly scaveng...

Background and Objective: Type 2 Diabetes Mellitus (T2DM) is among the epidemic metabolic chronic diseases that attenuates physiological functions, including hematopoiesis and immune responses, developing a higher risk of COVID-19 incidence. This study purposed to study the association of physical activity level (PAL) with the COVID-19 incidence in patients with T2DM. Materials and Methods: Al...

background: vitamin d deficiency may play a key role in the development of impaired glucose tolerance, type 2 diabetes mellitus (t2dm), and metabolic syndrome. several studies have shown that vitamin d has an antioxidant property. we aimed to investigate 25?hydroxy vitamin d (25[oh]d) levels in patients with t2dm and in nondiabetic healthy controls and to ascertain the impact of 25(oh)d levels ...

Mature soybean (Glycine max L. cv Harosoy 63) leaves normally contain kaempferol-3-glycosides but they accumulate no other flavonoids. Whole leaves sprayed with the diphenyl ether herbicide Acifluorfen and maintained in the light developed small necrotic lesions and accumulated isoflavone aglycones, isoflavone glucosides, and pterocarpans. Isoflavonoid accumulation was preceded by induced activ...

Oxidative processes play an important role in atherogenesis. Because superoxide anion and nitric oxide (NO) are important mediators in vascular pathology, we studied the expression of extracellular superoxide dismutase (EC-SOD) and inducible nitric oxide synthase (iNOS) in human and rabbit atherosclerotic lesions by using simultaneous in situ hybridization and immunocytochemistry and EC-SOD enz...

RATIONALE Increased oxidative stress and decreased superoxide dismutase (SOD) activity in the asthmatic airway are correlated to airflow limitation and hyperreactivity. We hypothesized that asthmatic individuals with higher levels of oxidative stress may have greater loss of SOD activity, which would be reflected systemically in loss of circulating SOD activity and clinically by development of ...

Phenylketonuria (PKU), with its associated hyperphenylalaninemia (HPA) and mental retardation, is a classic genetic disease and the first to have an identified chemical cause of impaired cognitive development. Treatment from birth with a low phenylalanine diet largely prevents the deviant cognitive phenotype by ameliorating HPA and is recognized as one of the first effective treatments of a gen...
