OXIDANTS AND ANTIOXIDANTS | Antioxidants, Nonenzymatic
2006Oxidant generation is part of the normal metabolism of many types of cells. To protect itself against exposure to noxious oxidants the lung has a well-developed antioxidant system. When an imbalance occurs between oxidants and antioxidants in favor of oxidants, oxidative stress is said to occur.

Exercise, depletion of antioxidants and antioxidant manipulation
Cell Biochemistry and Function, 1998Strenuous physical activity is known to increase the production of reactive oxygen species (ROS), associated with depletion of antioxidant defence. In the present work we evaluated the level of lipid peroxidation and antioxidant components in blood of sportsmen under resting conditions and compared the data obtained with those in age- and sex-matched ...

Antioxidants and antioxidant methods: an updated overview
Archives of Toxicology, 2020Antioxidants had a growing interest owing to their protective roles in food and pharmaceutical products against oxidative deterioration and in the body and against oxidative stress-mediated pathological processes. Screening of antioxidant properties of plants and plant-derived compounds requires appropriate methods, which address the mechanism of ...

Antiradical and antioxidant activities of new bio-antioxidants
Biochimie, 2012Antioxidants could be promising agents for management of oxidative stress-related diseases. New biologically active compounds, belonging to a rare class of natural lignans with antiangiogenic, antitumoral and DNA intercalating properties, have been recently synthesized.

Free Radical Research, 2013
The major causes for cataract formation are free radicals, and these free radicals are neutralized by the presence of endogenous antioxidants in the eye. Using xenobiotics, it has been confirmed that free radicals mediate the formation of cataract.

Nutrigenomics and Antioxidants
Personalized Medicine, 2007Since the complete sequencing of the human genome, the era of the 'omics' has appeared. Among them, a new discipline called 'nutrigenomics' emerged from the interface of nutrition research and genetics. Its aim is to understand how nutrients modulate gene expression. This powerful tool allows determinination of new biomarkers and the molecular pathways

Contact Dermatitis, 1984
Antioxidants are commonly added to cosmetics. Allergy to these substances will be missed unless specifically looked for. During a 2‐year period, patients with facial dermatitis have been routinely tested with butylhydroxyanisole and tertiary butylhydroquinone.

Scientific American, 2013
The article looks at research into the role of oxidative damage caused by free radicals in aging and the effectiveness of antioxidant vitamins to prevent age-related diseases. In a study of Caenorhabditis elegans worms genetically engineered to stop producing antioxidant enzymes, researchers found that the worms exhibited oxidative damage, but not ...

Oxidant agents, including reactive oxygen and nitrogen species (ROS and RNS, respectively) are molecules that can cause oxidative stress in tissues and organs. They are either endogenously produced during normal metabolism or they can come from the environment.
