Effect of peritoneal dialysis on antioxidant defense system and oxidative stress

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 ...

Inflammatory Activity and Oxidative Stress in Hemodialysis and Peritoneal Dialysis

Background. Some authors suggest that the inflammatory status is a factor, influencing the oxidative stress in dialysis patients. Evaluating the level of oxidative stress by two lipid peroxidation markers and its dependence on the chronic inflammation in patients treated by the two main methods of blood purification, this study intends to compare the inflammatory activity and the plasma levels ...

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...

Extreme Temperature Responses, Oxidative Stress and Antioxidant Defense in Plants

Oxidative Stress and Antioxidant System in Periodontitis

Periodontitis is a common inflammatory disease, which is initiated by bacterial infection and subsequently progressed by aberrant host response. It can result in the destruction of teeth supporting tissues and have an influence on systemic health. When periodontitis occurs, reactive oxygen species, which are overproduced mostly by hyperactive neutrophils, could not be balanced by antioxidant de...
