The present controlled-training double-blind study (supplemented (S) group, n 7; placebo (P) group, n 10) was designed to investigate whether an antioxidant mixture (Se 150 microg, retinyl acetate mg, ascorbic acid 120 mg, alpha-tocopheryl succinate 20 mg) would allow overloaded triathletes to avoid adaptation failure in the antioxidant system [corrected]. Dietary intakes were recorded. The sup...

Vitamins have traditionally been considered as food components that are required in the normal diet to prevent deficiencies. However, a newer concept of the function of vitamins in nutrition has taken them beyond simply prevention of deficiency symptoms.

It is generally agreed that reactive oxygen species (ROS) contribute to skin aging, skin disorders, and skin diseases. Skin possesses an extremely efficient antioxidant system. This antioxidant activity is conferred by two systems: antioxidant enzymes and small molecules that can scavenge ROS by donating electrons. No gene-encoded secreted ROS scavengers have been reported. Amphibian skin is a ...

Oxidative stress is an important feature in the pathogenesis of COPD. Targeting oxidative stress with antioxidants or boosting the endogenous levels of antioxidants is likely to be beneficial in the treatment of COPD. Antioxidant agents such as thiol molecules (glutathione and mucolytic drugs, such as N-acetyl-L-cysteine and N-acystelyn), dietary polyphenols (curcumin, resveratrol, green tea, c...

0892-6638/92/0006-2675/$01.50. © FASEB 2675 ABSTRACT Free radicals generated by a partial reduction of 02 pose a serious hazard to tissues and vital organs, especially membrane lipids, connective tissues, and the nucleic acids of cells. For protection, enzymes have evolved that specifically attack Of, hydrogen, and organic peroxides, and repair any damage incurred to DNA. With few exceptions, a...

Introduction T h e potential importance of oestrogens as antioxidant cardioprotectants is currently attracting considerable attention. Oestrogen is recognized to have a protective effect against coronary heart disease and its antioxidant action could contribute to the cardiovascular benefits observed on oestrogen administration in postmenopausal women [ 1,2]. This antioxidant-mediated cardiopro...

HIV infection is characterized by many immunological, neurological and metabolic abnormalities. The intra and extra cellular redox balance also is severely disturbed in HIV-infected individuals. The tripeptide glutathione (GSH) is the main intracellular defense against oxidative stress and regulates the cellular redox potential. Other antioxidant systems, such as thioredoxin, vitamin C, vitamin...
