Nutraceuticals against Oxidative Stress in Autoimmune Disorders

Oxidative Stress in Human Autoimmune Joint Diseases

Living with oxygen is basically unsafe, but vital. During evolution, oxygen originally a waste product of the metabolism in primitive unicellular organisms became normal product of the metabolism in higher animal species involving humans. Even when oxidative reactions are toxic, and destructive, they are tolerated by all organisms to some extent. The fact has opened the discussion about efficie...

Protection against Oxidative Stress

Oxidative Stress and Neurodegenerative Disorders

Living cells continually generate reactive oxygen species (ROS) through the respiratory chain during energetic metabolism. ROS at low or moderate concentration can play important physiological roles. However, an excessive amount of ROS under oxidative stress would be extremely deleterious. The central nervous system (CNS) is particularly vulnerable to oxidative stress due to its high oxygen con...

Oxidative Stress and Psychological Disorders

Oxidative stress is an imbalance between cellular production of reactive oxygen species and the counteracting antioxidant mechanisms. The brain with its high oxygen consumption and a lipid-rich environment is considered highly susceptible to oxidative stress or redox imbalances. Therefore, the fact that oxidative stress is implicated in several mental disorders including depression, anxiety dis...

Preventive or Potential Therapeutic Value of Nutraceuticals against Ionizing Radiation-Induced Oxidative Stress in Exposed Subjects and Frequent Fliers

Humans are constantly exposed to ionizing radiation deriving from outer space sources or activities related to medical care. Absorption of ionizing radiation doses over a prolonged period of time can result in oxidative damage and cellular dysfunction inducing several diseases, especially in ageing subjects. In this report, we analyze the effects of ionizing radiation, particularly at low doses...
