Aging is associated with a pro-oxidant state and a decline in endothelial function. Whether acute, enteral antioxidant treatment can reverse this decrement in vascular function is not well known. Flow-mediated vasodilation and reactive hyperemia were evaluated after consumption of either placebo or an oral antioxidant cocktail (vitamin C, 1000 mg; vitamin E, 600 IU; -lipoic acid, 600 mg) in 87 ...
BACKGROUND Increased oxidative stress is a hallmark of end-stage renal disease (ESRD). Glutathione S-transferases (GST) are involved in the detoxification of xenobiotics and protection of oxidative damage. We hypothesized that genetic polymorphism in antioxidant enzymes GSTA1, GSTM1, GSTP1 and GSTT1 is more frequent in ESRD and modulates the degree of oxidative stress in these patients. METHO...
Okra (A.esculentus) is an antidiabetic plant that it's beneficial effects on ovarian dysfunction in diabetes condition has not been clarified. The present study was designed to examine the effect of Okra powder on serum oxidant/antioxidant status, ovarian structure and expression of apoptotic/antiapoptotic related genes in ovary of experimentally induced high fat diet diabetic rats. Diabetes wa...
DESIGN In order to characterize whether different degrees of adipose tissue storage may be associated with markers of early atherosclerosis, we evaluated oxidant-antioxidant status and inflammatory markers and determined carotid intima-media thickness (cIMT) in healthy constitutional lean and obese pre-pubertal children. METHODS Eighty healthy pre-pubertal lean and obese children were recruit...

Radiation-induced free radicals are considered to initiate and perpetuate the action of ionizing radiation (IR) on living organisms, causing mutations, cell apoptosis or even genetic instability. Oxidative processes play an important role in the pathogenesis of several diseases (e.g. neurodegenerative and cardiovascular diseases or cancer). In contrast, some authors state that a ‘radiation adap...
Thymocytes exposed to the pro-oxidant tert-butyl-hydroperoxide (ButOOH) display a number of dramatic changes in morphology similar to those observed in the case of dexamethasone-treated cells. Both reagents induce nuclear chromatin peripheral aggregation below the nuclear membrane. Some nuclei themselves break up producing two or more fragments. ButOOH-treated cells are morphologically characte...
Inhaled corticosteroids (ICS) are widely used for the treatment of COPD despite of controversial statements concerning their efficacy. The use of N-acetylcysteine (NAC), a mucolytic drug with antioxidant properties, is less clear, but it may counteract the oxidant-antioxidant imbalance in COPD. The aim of this study was to evaluate whether treatment of COPD patients with ICS or NAC is able to i...
