Although acute exercise is apparently pro-inflammatory and increases oxidative stress, it can promote the necessary stress stimulus to train chronic adaptations in patients with chronic heart failure (CHF). This study aimed to compare the effects of exercise intensity and duration on the inflammatory mar...

In this study, we aim to examine effects of an experimentally induced unilateral varicose ovarian vein on the activities of anti-oxidant enzymes in an adult rat ovary. In this experimental study, a total of 30 adult female Wistar albino rats were divided into three groups. 10 rats in group 1 as the varic...
Abstract Introduction: Oxidative stress seems to be a role in the atherosclerosis process, but research in human beings is scarce. Objective: To evaluate the role of oxidative stress on human aortas of patients submitted to surgical treatment for advanced aortoiliac occlusive disease. Methods: Twenty-...

ABSTRACT PURPOSE: To evaluated the role of oxidative stress on aging process in patients submitted to carotid endarterectomy. METHODS: Twenty patients were divided into two groups: older group (≥ 70 years old); and the younger group (< 70 years old). We evaluated the reactive oxygen species ...
ABSTRACT PURPOSE: To determine the toxic effect of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) on reproductive system and the beneficial effects of Montelukast (ML) with histological and biochemical analysis. METHODS: Rats were randomly divided into four equal groups (control, TCDD, ML and TCDD+ML). Ti...
