fish larvae experience major cellular and biochemical changes during their early life stages.the aim of the present study was to evaluate alterations in the antioxidant status and values oflipid peroxidation and vitamin c content during the different life developmental stages ofhypophthalmichthys molitrix. eggs and larvae were sampled at fertilization, organogenesis,eyed egg, hatch, active feed...

effects of salinity and drought on growth, contents of proline, malondialdehyde (mda), proteinand activity of antioxidative enzymes were studied in two trigonella species. seeds andexplants of t. foenum-graecum and t. aphanoneura were grown on murashige and skoogmedium (ms) complemented with iso-osmotic concentrations of nacl (0, 100, 150 mm) andmannitol (0, 180, 275 mm). growth and relative wa...

despite the preventative and therapeutic effects of regular exercise, exhaustive exercise may be harmful to health. the present study aimed to determine the protective effect of endurance training and cinnamon bark extract (cbe) supplementation on oxidative responses induced by an exhaustive exercise schedule in rats. the rats were randomly divided into the following five groups of 6; control s...

conclusions contrast-agent-induced nephropathic changes are more closely related to the magnitude of lipid peroxidation than protein oxidation. results compared with the control group, groups cin and n + cin had significantly higher urea and lhp levels (p < 0.05 and p < 0.001, respectively) and significantly lower cu, zn-sod activity and creatinine clearance (p < 0.05). there was no statistical...

background and objectives: parkinson&apos;s disease (pd) is a common neuropathologic disorder that is caused by degeneration of dopaminergic neurons of dense part of nigra. oxidative stress has been found in the pathophysiology of pd. since α-pinene has strong anti-oxidant effects, the purpose of this research was to study its effects on movement disorders and memory and lipid peroxidation in p...

background: the lipid peroxides and their degradation products are highly toxic to spermatozoa and may play a major role in sperm dysfunction. the purpose of this study was to determine the level of lipid peroxidation as indicated by malondialdehyde (mda) in the spermatozoa and seminal plasma of asthenozoospermic and normozoospermic males. in addition, correlation of lipid peroxidation with mot...

background: nitric oxide (no) is synthesized from l-arginine by a family of enzymes known as nitric oxide synthases. low concentrations of no is essential in biology and physiology of spermatozoa, but high amounts of no is toxic and has negative effects on sperm functions. moreover, sperm membrane contains high concentrations of polyunsaturated fatty acids that are highly susceptible to oxidati...

objective(s):acrylamide (acr) has broad applications in different industries. it also forms in food during heating process. oxidative stress has a critical role in acr-induced neurotoxicity in both in vitro and in vivo models; therefore, the aim of the current study was the evaluation of effects of thymoquinone, the main constituent of volatile oil from nigella sativa seeds in acr-induced neuro...

objective(s):this study was planned to appraise the protective effect of nigella sativa fixed oil (nso) against subchronic ethanol induced toxicity in rats. materials and methods: studies were carried out on six groups of six animals each, including control (normal saline, gavage), ethanol (3 g/kg/day, gavage), nso (0.125, 0.25 and 0.5 ml/kg/day, ip) plus ethanol and nso (0.5 ml/kg/day, ip) gro...

background: exercise can change the release of numerous cytokines and modulate their receptor systems. dietary ω-3 lipids may decrease the levels of inflammatory cytokines and prostaglandins (pgs). therefore, in this study, we investigated the effects of exercise and eicosapentaenoic acid (epa) supplementation, with or without vitamin e, on the blood levels of il-2, tnf-α, catalase, glutathione...
