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.

Current Opinion in Nephrology and Hypertension, 1998
Increasing evidence implicates reactive oxygen species in the pathogenesis of hypertension and its cardiovascular complications. By altering the balance in the endothelium between vasoconstrictors such as thromboxane and isoprostanes and vasodilators such as nitric oxide, reactive oxygen species contribute to endothelium-dependent contractions and ...

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.

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

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.

In order to ascertain the role of dietary flavonoids as antioxidants in vivo it is necessary to understand the chemical nature of the absorbed forms in the circulation in vivo and how the multiplicity of research findings in vitro reflect the bioactivity of flavonoids in vivo. Only when we gain adequate information on the circulating forms can we begin

Overproduction of superoxide by the mitochondrial electron transport chain is the common link between the various pathways of glucotoxicity. The increased oxidative byproducts in diabetes are the result of a glucose-induced increase in the production of reactive oxygen species and decreased antioxidant defense capacity.
