Despite the knowledge on the antiatherogenic effects of exercise, the mechanism by which exercise reduces atherogenic risk remains unknown. In this study, we investigated the hypothesis that chronic exercise-induced oxidative stress may increase plasma total antioxidant capacity and antioxidant defense in the red cells. For 8 weeks, 60 male Dutch rabbits were fed rabbit chow with or without the...

Aims. Maternal smoking is considered as a source of oxidative stress, which has been implicated to disrupted adipokines expression in adipose tissue. We examined the relationship between selected adipokines and markers of oxidative stress/antioxidant defence in the umbilical cord of neonates exposed and nonexposed in utero to tobacco smoke. Methods. Subjects including 85 healthy neonates (born ...

Reactive oxygen species (ROS) generation, induced by the cryopreservation process, can be responsible for mammalian sperm damage. Curcumin is known as an effective antioxidant against oxidative stress. The aim of this study was to evaluate the effects of curcumin on sperm count, motility and viability, semen total antioxidant capacity and DNA integrity of rat spermatozoa during semen freeze-tha...

objective (s): there is corroborating evidence to substantiate redox imbalance and oxidative stress in sepsis that finally leads to organ damage or even death. gamma oryzanol (go) is one of the major bioactive components in rice bran has been considered to function as an antioxidant. the present study was carried out to evaluate the antioxidant activity of gamma oryzanol in vitro and its effica...

We aimed to investigate whether agoraphobia (A) in panic disorder (PD) has any effects on oxidative and anti-oxidative parameters. We measured total antioxidant capacity (TAC), paraoxonase (PON), arylesterase (ARE) antioxidant and malondialdehyde (MDA) oxidant levels using blood samples from a total of 31 PD patients with A, 22 PD patients without A and 53 control group subjects. There was a si...

Background: N-acetylcysteine (NAC) is a putative antioxidant and has gained attention as a promising agent for chelating heavy metals including lead. Considering the animal studies results, we hypothesized that adding NAC to the treatment regimen may improve the success of treatment with lead chelators. Methods: A total of 46 patients who were lead-poisoned opioid addicts were divided into two ...

background antioxidant effects of propofol (2, 6-diisopropylphenol) were evaluated against cisplatin-i‎nduced oxidative stress in rat. objectives in this experimental study, 20 male rats were equally divided into 4 groups (5 rats each), and were treated by propofol (10 mg/kg/day, ip), or cisplatin (7 mg /kg/day, ip), or both. conclusions it is concluded that oxidative ‎damage is the mechanism o...

Introduction: Oxidative stress is an imbalance between the formation of Reactive oxygen species and protective antioxidant defense. It is known that oxidative stress increases the Acute renal failure. Measurement of oxidative stress parameters may be a simple tool for monitoring the progression of acute renal failure. Aim: The aim of this study was to evaluate oxidative stress in acute renal fa...

There is some evidence showing an inverse correlation between dietary sources including natural antioxidant vitamins and the risk of cardiovascular disease (CVD). The aim of this study was to evaluate the effect of dietary antioxidants on oxidative stress in CVD patients. This study was carried out on 31 CVD patients and 63 healthy individuals. Nutritional status and dietary antioxidant vitamin...

Background: The cigarette compounds are associated with the increase in the incidence of oral cancer andprecancerous lesions. Salivary antioxidant system plays an important role in anti-carcinogenic capacity ofsaliva. Cotinine, a nicotine metabolite, has a longer half-life in comparison with nicotine and is a suitablemarker for exposure to cigarette smoke. This study aims to measure total antio...
