EXPLORE, 2009
Abstract Patients with cancer are taking antioxidant supplements in combination with conventional chemotherapy and radiotherapy to enhance the anticancer activity and to reduce the side effects of conventional treatment. Many oncologists are concerned that the protective mechanisms of antioxidants may not distinguish between normal and ...

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

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.

Physiological Measurement, 2007
Chemical reactions, including oxidation and reduction of molecules, occur in every cell. These reactions can lead to the production of free radicals. Free radicals react with organic substrates such as lipids, proteins, and DNA. Through oxidation free radicals cause damage to these molecules, disturbing their normal function, and may therefore ...

Journal of Natural Products, 2000
Flavonoids are phenolic substances isolated from a wide range of vascular plants, with over 8000 individual compounds known. They act in plants as antioxidants, antimicrobials, photoreceptors, visual attractors, feeding repellants, and for light screening.

Antioxidant Compounds and Antioxidant Activity in “Early Potatoes”
Journal of Agricultural and Food Chemistry, 2008The antioxidant content and the antioxidant capacity of both hydrophilic and lipophilic antioxidant extracts from four "early potato" cultivars, grown in two different locations (Racale and Monteroni), were examined. There was a considerable variation in carotenoid content and weak differences in the ascorbic acid concentration of the examined ...

Antioxidants and Micronutrients
Disease-a-Month, 2006ver the last two decades, we have seen a tremendous increase in onsumer use of antioxidants and other micronutrient supplements for educing risk of disease prevention and ailments. There is therefore a rowing need to understand the characteristics, tissue uptake, metabolism, iochemical interactions, and the biological activities of various dietary ...

Antioxidants and atherosclerosis
Biochemical Society Transactions, 2004The oxidative modification of low-density lipoprotein (LDL) can be induced by various active species by different mechanisms. Vitamin E and other radical-scavenging antioxidants can inhibit the free radical-mediated oxidation of LDL, but they are not effective against LDL oxidation induced by non-radical mechanisms.

Cyclodextrins and Antioxidants
Critical Reviews in Food Science and Nutrition, 2013In recent years, the growth of the functional foods industry has increased research into new compounds with high added value for use in the fortification of traditional products. One of the most promising functional food groups is those enriched in antioxidant compounds of a lipophilic nature.

Antioxidants and Osteoarthritis
2014© Springer-Verlag Berlin Heidelberg 2014. All rights are reserved. Oxidative stress produces reactive oxygen species (ROS) that play key roles in the development of osteoarthritis (OA) and rheumatoid arthritis (RA). Metabolic reactions in chondrocytes and synoviocytes produce free radicals, ROS, and their derivatives.
