Dietary oxidative stress and antioxidant defense with an emphasis on plant extract administration

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 ...

Supplementation with gliadin-combined plant superoxide dismutase extract promotes antioxidant defences and protects against oxidative stress.

The potential benefits to health of antioxidant enzymes supplied either through dietary intake or supplementation is still a matter of controversy. The development of dietary delivery systems using wheat gliadin biopolymers as a natural carrier represents a new alternative. Combination of antioxidant enzymes with this natural carrier not only delayed their degradation (i.e. the superoxide dismu...

Relationship between Dietary Total Antioxidant Capacity and Oxidative Stress Markers in Patients with Knee Osteoarthritis

Background and purpose: Considering the pathologic importance of oxidative stress in osteoarthritis (OA), this study aimed to investigate the association between dietary total antioxidant capacity (DTAC) and oxidative stress markers in patients with knee OA. Materials and methods: In a cross-sectional study, dietary intakes of 152 patients with knee OA attending health centers in Zabol, Iran (...

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...
