We aimed to investigate the relation between serum inflammatory markers, 25OHvit-D3 and oxidative stress markers, namely paraoxonase1-arylesterase (PON1-ARE), total antioxidant status (TAS) and total oxidant status (TOS) in 30 male patients with ST-elevation myocardial infarction(STEMI) . There was negative correlation between tumor necrosis factor alpha and ARE; positive correlations between s...
OBJECTIVE To examine the effects of increased sperm DNA damage in relation to seminal oxidative stress in men with idiopathic and male factor infertility. Prospective study. SETTINGS Infertility clinic at a tertiary care academic institution. PATIENT(S) Ninety-two infertile men with normal female partners. Sixteen fertile donors served as the control group. INTERVENTION(S) Standard semen ...
The ocular surface is always attacked by oxidative stress, and cornea epithelial cells are supposed to have their own recovery system against oxidative stress. Therefore we hypothesized that tears supply key molecules for preventing oxidative stress in cornea. The potential target key molecule we focused is selenoprotein P (SeP). SeP is a carrier of selenium, which is an essential trace element...
background: in the recent years, various studies have shown a link between the free radicals, antioxidants and periodontal diseases. the purpose of the present study was to evaluate the oxidative stress and the antioxidant status present in the gingival tissue and plasma of patients with chronic periodontitis and to evaluate the antioxidant property of taurine. materials and methods: periodonta...
background and objective: in neurodegenerative disorders, oxidative stress mediated by reactive oxygen species is strongly associated with increased neuronal damages that lead to apoptosis. pro-apoptotic and anti-apoptotic gene expressions were changed during cell differentiation that affect cell viability and differentiation. this study was conducted to determine the effects of hydrogen peroxi...
Inflammatory abnormalities may be involved in the inadequate basal oxidant/antioxidant balance and local exercise-induced oxidative stress in chronic obstructive pulmonary disease (COPD) patients. The time course of oxidative stress and inflammation was investigated in 10 COPD patients and seven healthy subjects before and after local dynamic quadriceps endurance exercise at 40% of maximal stre...
BACKGROUND AND AIMS Periodontitis is a chronic inflammation that involves nitro-oxidative stress with damaging periodontal structural effects. We aimed to evaluate the consequences of low-dose cimetidine on nitro-oxidative stress in periodontitis. METHODS A rat model of ligature-induced periodontitis was used. After two weeks, the periodontitis groups were treated with cimetidine, aminoguanid...
statins have antioxidant and anti-inflammatory effects that are not directly related to their cholesterol-lowering activity. this study aimed to investigate the effect of simvastatin on the extent of tissue damage in cisplatin-induced nephrotoxicity. simvastatin was orally given to rats in different doses (1, 2 and 4 mg/kg), 1 h prior to cisplatin injection (5 mg/kg, i.p.). all animals were dec...
background: prepubertal varicocele has the most devastating effects on the testes. oxidative stress is the major cause leading to infertility in varicocele. the antioxidant properties of flaxseed (fs) treatment in some oxidative diseases have been reported. objective: this study aimed to evaluate the antioxidant effect of fs in prepubertal rats with experimental varicocele. materials and method...
introduction: acrylamide (acr) known as a neurotoxic agent in human and animals. previous studies have been shown; fasudil improves neurological deficit and neuronal damage. in this study, the effect of fasudil, potent rho-kinase inhibitor, on acr-induced cytotoxicity was evaluated using pc12 cells as a suitable in vitro model. materials and methods: pc12 cells were exposed to different concent...
