conclusions beta-alanine supplementation has limited antioxidant effect during the repeated wts. background carnosine is a dipeptide formed from the β-alanine and histidine amino acids and found in mainly in the brain and muscle, especially fast twitch muscle. carnosine and creatine has an antioxidant effect and carnosine accounts for about 10% of the muscle's ability to buffer the h+ ions prod...
BACKGROUND Hemodynamically significant patent ductus arteriosus (hsPDA) leads to injury in tissues/organs by reducing perfusion of organs and causing oxidative stress. The purpose of this study was to evaluate the oxidant/antioxidant status in preterm infants with hsPDA by measuring the total antioxidant capacity and total oxidant status and to assess neuronal damage due to oxidant stress relat...
Introduction: The effects of Ramadan observance and any associated dietary restriction upon oxidative stress are not well known. The topic has thus been examined in a brief systematic review of available literature concerning non-athletic but otherwise healthy subjects, patients with selected clinical conditions, and in athletes. Methods: Ovid/Medline and Google searches were supplemented by a ...
OBJECTIVES To determine the oxidant - antioxidant imbalance in asthmatic children, by measuring the levels of malondialdehyde (MDA) as an oxidant marker of lipid peroxidation as well as antioxidant compounds like vitamin C, vitamin E and uric acid and to investigate whether their concentrations are associated with more severe asthma. METHODS This case controlled prospective study was conducte...
BACKGROUND & OBJECTIVES Contrast media may cause contrast-induced nephropathy (CIN) in risk group. This study was taken up to establish possible effects of non ionic low osmolar contrast medium administration on oxidant/antioxidant status and nitric oxide (NO) levels in rat kidney tissues. METHODS Fourteen female, 14 wk old Wistar-albino rats were divided into 2 groups of 7 rats each (control...
OBJECTIVES This study investigated the effects of melatonin, famotidine, mirtazapine, and thiamine pyrophosphate on ischemia/reperfusion (I/R) injury in diabetic rats and evaluated oxidant and antioxidant marker measurement results. It also examined the effects of the drugs aimed at preventing infertility that may result from I/R injury. MATERIALS AND METHODS Diabetic rats were divided into a...
Cells that utilize molecular oxygen generate highly reactive oxygen-derived free radicals. Endogenous cellular oxidants inactivate oxidant free radicals and protect aerobic cells from oxidant injury. Glutathione, glutathione reductase, and superoxide dismutase are key components of this antioxidant defense. Inhibition of antioxidant components would be expected to result in cell injury. Using e...
