Oxidative shielding or oxidative stress?
In this review I report evidence that the mainstream field of oxidative damage biology has been running fast in the wrong direction for more than 50 years. Reactive oxygen species (ROS) and chronic oxidative changes in membrane lipids and proteins found in many chronic diseases are not the result of accidental damage. Instead, these changes are the result of a highly evolved, stereotyped, and p...

متن کاملQuinolinic Acid: Neurotoxin or Oxidative Stress Modulator?
Quinolinic acid (2,3-pyridinedicarboxylic acid, QUIN) is a well-known neurotoxin. Consequently, QUIN could produce reactive oxygen species (ROS). ROS are generated in reactions catalyzed by transition metals, especially iron (Fe). QUIN can form coordination complexes with iron. A combination of differential pulse voltammetry, deoxyribose degradation and Fe(II) autoxidation assays was used for e...
متن کاملOxidative Stress in Neurodegeneration
It has been demonstrated that oxidative stress has a ubiquitous role in neurodegenerative diseases. Major source of oxidative stress due to reactive oxygen species (ROS) is related to mitochondria as an endogenous source. Although there is ample evidence from tissues of patients with neurodegenerative disorders of morphological, biochemical, and molecular abnormalities in mitochondria, it is st...
متن کاملOxidative Stress and Schizophrenia
Many studies show that oxidative stress is a pathophysiological mechanism of schizophrenia. Elevated oxidative stress levels and the damage to the antioxidant defense system can observed in early schizophrenia. High oxidation levels damage lipids, proteins, nucleic acids and other tissues. Antioxidant defense system imbalance has been observed in both neuroleptic-naïve first-episode schizophren...
