Absence of oxidative stress following paradoxical sleep deprivation in rats
(Elsevier B.V., 1997-10-10)Paradoxical sleep deprivation was performed on rats using platform technique to investigate the oxidative process associated with it. Levels of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), total ...

Acute stressor-selective effects on homocysteine metabolism and oxidative stress parameters in female rats
(Elsevier B.V., 2006-10-01)Homocysteine levels are affected by diet factors such as vitamin deficiencies, non-diet factors such as genetic disorders, and stress exposure. Hyperhomocysteinemia has been implicated in several disorders, including ...

Aerobic exercise affects C57BL/6 murine intestinal contractile function
(Springer, 2008-05-01)This study investigated the influence of a moderate exercise training program on the intestinal contractility based on the hypothesis that this organ may endure repetitive periods of ischemia-reperfusion events during ...

Age-dependent detection of erythrocytes glucose-6-phosphate dehydrogenase and its correlation with oxidative stress
(Taylor & Francis Ltd, 2016)Context: Glucose-6-phosphate dehydrogenase (G6PD) is an important enzyme of hexose monophosphate shunt, involved in the biosynthesis of reduced nicotinamide adenine dinucleotide phosphate hydrogen (NADPH). Objective: This ...

Antioxidant defense in rat brain after chronic treatment with anorectic drugs
(Elsevier B.V., 1995-11-15)Mazindol (5-hydroxy-5-p-chlorophenyl-2,3-dihydro-5H-isoindole) although not chemically related to the phenylethylamine group, shows a pharmacological profile similar to that of amphetamines. in rats these anorectic drugs ...

Antioxidant vitamins C and E supplementation increases markers of haemolysis in sickle cell anaemia patients: a randomized, double-blind, placebo-controlled trial
(Wiley-Blackwell, 2013-03-01)Erythrocytes from sickle cell anaemia (SCA) patients continuously produce larger amounts of pro-oxidants than normal cells. Oxidative stress seems to primarily affect the membrane and results in haemolysis. the use of ...

Association of polymorphisms of glutamate-cystein ligase and microsomal triglyceride transfer protein genes in non-alcoholic fatty liver disease
(Wiley-Blackwell, 2010-02-01)Background and Aims: Although the metabolic risk factors for non-alcoholic fatty liver disease (NAFLD) progression have been recognized, the role of genetic susceptibility remains a field to be explored. the aim of this ...
