Can dietary micronutrients influence tissue antioxidant capacity?
Numerous recent studies have indicated possible roles for free-radical-mediated processes in human pathology. This has led to a great interest in the substances thought to prevent the deleterious effects of these substances in vivo, the antioxidants. The biochemistry of free-radical reactions, the manner in which they damage cells and the antioxidants inhibiting their reaction with cellular con...

متن کاملMicronutrients: oxidant/antioxidant status.
Potentially damaging species (reactive oxygen, nitrogen and chlorine species) arise as by-products of metabolism and as physiological mediators and signalling molecules. Levels of these species are controlled by the antioxidant defence system. Several components of this system are micronutrients (e.g. vitamins C and E) or are dependent upon dietary micronutrients (e.g. CuZn and Mn superoxide di...
متن کاملTissue antioxidant capacity during anesthesia: propofol enhances in vivo red cell and tissue antioxidant capacity in a rat model.
UNLABELLED The effects of anesthesia on ischemia-reperfusion injury are of considerable scientific and clinical interest. We examined the effects of propofol (known to possess antioxidant activity) and halothane (devoid of antioxidant activity in vitro) on tissue and red blood cell (RBC) antioxidant capacity. Adult male Wistar rats were anesthetized with halothane 0.5%-1.0% (n = 7), propofol 50...
متن کاملThe Importance of Antioxidant Micronutrients in Pregnancy
Pregnancy places increased demands on the mother to provide adequate nutrition to the growing conceptus. A number of micronutrients function as essential cofactors for or themselves acting as antioxidants. Oxidative stress is generated during normal placental development; however, when supply of antioxidant micronutrients is limited, exaggerated oxidative stress within both the placenta and mat...
