Antioxidants from Plants Protect against Skin Photoaging [PDF]
Oxidative Medicine and Cellular Longevity, 2018 Exposure to UV light triggers the rapid generation and accumulation of reactive oxygen species (ROS) in skin cells, with consequent increase in oxidative stress and thus in photoaging. Exogenous supplementation with dietary antioxidants and/or skin pretreatment with antioxidant‐based lotions before sun exposure might be a winning strategy against age ...

Ocular Oxidants and Antioxidant Protection
Experimental Biology and Medicine, 1998 Oxidative damage and antioxidant protection in ocular tissues has not been reviewed recently. Metabolism in the eye is of increasing interest because the organ is highly susceptible to damage by sunlight, oxygen, various chemicals, and pollutants. Interest is expected to increase because of an aging Western world population and a continued depletion of

Aerobic Performance and Antioxidant Protection in Runners [PDF]
International Journal of Sports Medicine, 2009 Reactive oxygen species (ROS) production is known to increase as a result of muscular contractile activity and this phenomenon may perturb the fine-controlled cellular redox homeostasis within cells and tissues. We studied the possible correlations between individual aerobic performance-related factors and the oxidative stress markers profile in the ...

Protection of Bortezomib-induced Neurotoxicity by Antioxidants [PDF]
Anticancer Research, 2020 Although chemotherapy agents, such as oxaliplatin, cisplatin, paclitaxel and bortezomib frequently cause severe peripheral neuropathy, very few studies have reported the effective strategy to prevent this side effect. In this study, we first investigated whether these drugs show higher neuropathy compared to a set of 15 other anticancer drugs, and then

Biochemical indicators of green photosynthetic bacteria Chlorobium limicola response to Cu(2+) action [PDF]
The Ukrainian Biochemical Journal, 2020 Photolithotrophic sulfur bacteria are involved in biota functioning and have a biotechnological potential for bioremediation of contaminated environment, but the mechanisms of xenobiotics, in particular of heavy metal ions damaging action and the ...

Radio-protective role of antioxidant agents
Oncology Reviews, 2012 Ionizing radiation interacts with biological systems to produce reactive oxygen species and reactive nitrogen species which attack various cellular components. Radio-protectors act as prophylactic agents to shield healthy cells and tissues from the harmful effects of radiation.

Lipid peroxidation, antioxidant protection and aging
Biochimica et Biophysica Acta (BBA) - Molecular Basis of Disease, 1997 The free radical hypothesis of aging proposes that deleterious actions of oxygen-derived radicals are responsible for the functional deterioration associated with aging. Because cellular membranes house the production apparatus of these radicals and because membranes suffer great damage from these radicals, modification of membrane lipids has been ...
