introduction: the aim of the present study was to evaluate the effect of exercise training and l-arginine supplementation on oxidative stress and systolic ventricular function in rats with myocardial infarction (mi). methods: four weeks after the surgically-induced mi, 40 male wistar rats were randomly assigned to the following 4 groups (n=10): mi-sedentary control (sed) mi-exercise (ex) mi-sed...

Many degenerative diseases are associated with increased oxidative stress. Creatine has the potential to act as an indirect and direct antioxidant; however, limited data exist to evaluate the antioxidant capabilities of creatine supplementation within in-vivo human systems. This study aimed to investigate the effects of oral creatine supplementation on markers of oxidative stress and antioxidan...

Obesity and insulin resistance (IR) increase the risk for coronary heart disease; however, much of this risk is not attributable to traditional risk factors. We sought to determine whether weight loss associated with supervised aerobic exercise beneficially alters biomarkers of oxidative stress and whether these alterations are associated with improvements in measures of insulin resistance. Twe...

Routine exercise is widely recognized as cardioprotective. Exercise induces a variety of effects within the cardiovasculature, including decreased mitochondrial damage and improved aerobic capacity. It has been generally thought that the transient increase in oxidative stress associated with exercise initiates cardioprotective processes. Somewhat paradoxically, increased oxidative stress associ...

Introduction: Polycystic ovary syndrome (PCOS) is one of the most common endocrinological pathologies in women during their reproductive years with ovulatory dysfunction, abdominal obesity, hyperandrogenism and insulin resistance. The aim of the present research was to evaluate the total antioxidant capacity (TAC), total oxidant status (TOS), free testosterone, ovarian morphology and estrous cy...

Renal lipid accumulation exhibits slowly developing chronic kidney disease and is associated with increased oxidative stress. The impact of exercise on the obese- and oxidative stress-related renal disease is not well understood. The purpose of this study was to investigate whether a high-fat diet (HFD) would accelerate d-galactose-induced aging process in rat kidney and to examine the preventi...

Exercise training causes increased oxidative stress. Pistacia Atlantica Extract (Mastic) is known to have a protective effect against oxidative stress and inflammation. We examined the effects of exercise training with and without Pistacia Atlantica extract administration on antioxidant markers in vistar rats. Twenty-eight Vistar female rats (six to eight weeks old, 150-200 g weight) allocate...
