Inclusion of natural antioxidant compounds in fish feeds to counteract oxidative stress

open access: yesRevista 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.

Oxidative damage and carcinogenesis

open access: yesWspółczesna 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.

Oxidative damage, ageing, and life-history evolution: where now? [PDF]

open access: yes, 2012
The idea that resources are limited and animals can maximise fitness by trading costly activities off against one another forms the basis of life-history theory.

Nogo-A aggravates oxidative damage in oligodendrocytes

open access: yesNeural 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.

Potent antioxidant alpha lipoic acid reduces STZ-induced oxidative stress and apoptosis levels in the erythrocytes and brain cells of diabetic rats

open access: yes, 2023
Diabetes, which causes oxidative stress-induced neuronal damage, is still one of the most important chronic health problems in the world. It can cause serious cellular loss and damage throughout the course of the disease.

Lung Oxidative Damage by Hypoxia [PDF]

open access: yesOxidative Medicine and Cellular Longevity, 2012
One of the most important functions of lungs is to maintain an adequate oxygenation in the organism. This organ can be affected by hypoxia facing both physiological and pathological situations. Exposure to this condition favors the increase of reactive oxygen species from mitochondria, as from NADPH oxidase, xanthine oxidase/reductase, and nitric oxide

Acute ethanol gavage attenuates hemorrhage/resuscitation-induced hepatic oxidative stress in rats [PDF]

open access: yes, 2012
Acute ethanol intoxication increases the production of reactive oxygen species (ROS). Hemorrhagic shock with subsequent resuscitation (H/R) also induces ROS resulting in cellular and hepatic damage in vivo.

Investigation of Neurotoxicity Oxidative Stress and Oxidative DNA Damage in Cadmium-Induced Brain Injury in Rats

open access: yes, 2023
Cadmium, which is one of the toxic metals widely used in many areas of the world, is taken intothe body in different ways. In this study, the damage caused by cadmium in the brain and howthis damage affects the levels of glial fibrial acidic protein, 8 ...

Polyamine catabolism and oxidative damage [PDF]

open access: yesJournal of Biological Chemistry, 2018
Polyamines (PAs) are indispensable polycations ubiquitous to all living cells. Among their many critical functions, PAs contribute to the oxidative balance of the cell. Beginning with studies by the Tabor laboratory in bacteria and yeast, the requirement for PAs as protectors against oxygen radical-mediated damage has been well established in many ...

Genotypic Diversity of Cross-Tolerance to Oxidative and Drought Stresses in Rice Seedlings Evaluated by the Maximum Quantum Yield of Photosystem II and Membrane Stability

open access: yesPlant Production Science, 2013
The genotypic variation of oxidative damage under oxidative and drought stresses was evaluated for a total of 67 rice cultivars consisting of 61 from the rice diversity research set of germplasm and 6 high-yielding varieties. The maximum quantum yield of
