Oxidative Stress and Defense System in vivo.

Oxidative Stress and Antioxidant Defense

Reactive oxygen species (ROS) are produced by living organisms as a result of normal cellular metabolism and environmental factors, such as air pollutants or cigarette smoke. ROS are highly reactive molecules and can damage cell structures such as carbohydrates, nucleic acids, lipids, and proteins and alter their functions. The shift in the balance between oxidants and antioxidants in favor of ...

oxidative stress and anti-oxidant defense system in iranian women with polycystic ovary syndrome

background: polycystic ovary syndrome (pcos) is a common disorder of infertility which affects more than 100 million women. it is characterized by chronic anovulation, hyper androgenism and obesity. pcos is also associated with oxidative stress changes. objective: here, we aimed to investigate the level of antioxidants and oxidative stress in iranian women with pcos as a predictive factor for c...

Oxidative stress and antioxidant defense in Egyptian favism patients.

BACKGROUND Favism occurs as the result of intolerance to the ingesting of fava beans or to the inhalation of pollen from the Vicia faba plant. Patients with favism are always Glucose-6-phosphate dehydrogenase (G6PD)-deficient, but not all G6PD-deficient individuals develop hemolysis as a result of fava beans consumption. PATIENTS AND METHODS Blood samples were collected from children with fav...
