sperm is particularly susceptible to reactive oxygen species (ros) during critical phases of spermiogenesis. however, the level of seminal ros is restricted by seminal antioxidants which have beneficial effects on sperm parameters and developmental potentials. mitochondria and sperm plasma membrane are two major sites of ros generation in sperm cells. besides, leukocytes including polymer phonu...
Niemann-Pick C disease (NPC) is an autosomal recessive neurodegenerative disorder caused by the abnormal function of NPC1 or NPC2 proteins, leading to an accumulation of unesterified cholesterol and glycosphingolipids (GSLs) in the lysosomes. The mechanisms underlying the pathophysiology in NPC disease are not clear. Oxidative damage is implicated in the pathophysiology of different neurologica...
exposure to air pollutants, steel dust or other occupational and environmental hazards as oxidative stress have adverse effects on subway workers' health. oxidative stress generates an excessive amount of reactive oxygen species (ros) and oxygen free radicals during their work time in the tunnels. once dna is repaired, urinary 8-hydroxy-deoxyguanosine (8-ohdg) is excreted in the urine. therefor...

background: this study investigated the protective effects of aqueous extracts of anogeissus leiocarpus (dc) guill & perr (combretaceae) and terminalia avicennioides guill & perr (combretaceae) root barks, as well as their 1:1 (w/w) mixture on liver redox and haematological parameters of diethylnitrosamine-treated rats. methods: rats were orally administered distilled water, diethylnitrosamine ...
introduction: the role of ovarian hormones and nitric oxide (no) on oxidative damage in brain tissues as well as learning and memory has been widely investigated.the present study was carried out to evaluate the effect of the precursor of no, l-arginine on learning and brain damage due to oxidative stress in ovariectomized (ovx) rats.methods: thirty -two rats were divided into four groups: 1) s...
background: diabetes is one of the most common metabolic disorders and is related to oxidative-stress-induced diseases. given the role of dietary antioxidants in the control and prevention of diabetes, this study aimed to examine the effects of sesame butter versus sesame oil on the serum levels of glucose, lipid profile, and oxidative stress biomarkers in diabetic rats. methods: forty male alb...
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...
objective(s): oxidative stress has been established as a key cause of alcohol-induced hepatotoxicity. licochalcone b, an extract of licorice root, has shown antioxidative properties. this study was to investigate the effects and mechanisms of licochalcone b in ethanol-induced hepatic injury in an in vitro study. materials and methods: an in vitro model of ethanol-induced cytotoxicity in brl cel...
