methylsulfonylmethane (msm) is a sulfur-containing compound commonly found in diet and known to reduce oxidative stress. this trial was conducted to determine whether single dose supplementation with msm attenuates post-exercise oxidative stress in healthy untrained young men. sixteen untrained men volunteered for this study. participants were randomized in a double-blind placebo-controlled fas...

In this study18 female sheep aged between 20-25 months was used in this experiment in alqasim city .the mow procedure was performed in a closed area using traditional method with shearers. The aim of study was to evaluate the stress response and the oxidant antioxidant balance against shearing process in sheep. Blood malonaldldhyde (MDA)and glutathione (GSH)concentration , were measured in 18 f...

Since "free radical research" started in 1954, understanding the role of oxidants and antioxidants in physiological and pathological conditions has increased continuously. Oxidants are essentially generated by metabolic enzymes, inflammatory cells and mitochondrial electron leakage; they are indispensable for the cellular redox regulation and may, under certain conditions, have a pro-inflammato...

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/AIMS Helicobacter pylori infection has been suggested to be associated with atherosclerosis. The issue is still controversial. It is well known that abnormal lipid profile and oxidative stress are related to atherosclerosis and the measurement of carotid intima-media thickness. The aim of this study was to investigate carotid intima-media thickness and oxidative stress along with lip...

INTRODUCTION The surgical stress response after laparoscopy is smaller when compared with open surgery, and it is expected that after minimally invasive surgery the possible development of oxidative stress will be less severe. AIM To evaluate markers of pro-oxidant activity - levels of lipid peroxides and malondialdehyde - and activity of the antioxidant enzymes superoxide dismutase and gluta...
