Inclusion of natural antioxidant compounds in fish feeds to counteract oxidative stress
Revista Bio Ciencias, 2015 Oxidative stress is a type of damage caused by different kinds of pollutants such as xenobiotics, or by a deficiency in the body’s own antioxidant mechanisms.

Common Mitochondrial DNA Mutations Generated through DNA-Mediated Charge Transport [PDF]
, 2009 Mutation sites that arise in human mitochondrial DNA as a result of oxidation by a rhodium photooxidant have been identified. HeLa cells were incubated with [Rh(phi)2bpy]Cl3 (phi is 9,10-phenanthrenequinone diimine), an intercalating photooxidant, to ...

Superoxide Dismutase (SOD)-mimetic M40403 is protective in cell and fly models of paraquat toxicity: Implications for Parkinson disease [PDF]
, 2016 Parkinson disease is a debilitating and incurable neurodegenerative disorder affecting 3c1-2% of people over 65 years of age. Oxidative damage is considered to play a central role in the progression of Parkinson disease and strong evidence links chronic

Overexpression of beta-carotene hydroxylase enhances stress tolerance in Arabidopsis [PDF]
, 2002 Plant stress caused by extreme environmental conditions is already a principal reason for yield reduction in crops. The threat of global environment change makes it increasingly important to generate crop plants that will withstand such conditions ...

Oxidative damage and carcinogenesis
Współczesna Onkologia, 2012 Oxygen is an essential element to conduct life processes but some of the metabolic byproducts e.g. reactive oxygen species (ROS), are toxic for living organisms. Endogenous ROS are produced e.g. reduction of dioxygen; some exogenous sources of radicals also exist, including nicotine and ionizing radiation.

Nogo-A aggravates oxidative damage in oligodendrocytes
Neural Regeneration Research, 2021 Nogo-A is considered one of the most important inhibitors of myelin-associated axonal regeneration in the central nervous system. It is mainly expressed by oligodendrocytes.
