Oxidative Stress in Bacteria and the Central Dogma of Molecular Biology

Frontiers in Molecular Biosciences, 2021
Ever since the “great oxidation event,” Earth’s cellular life forms had to cope with the danger of reactive oxygen species (ROS) affecting the integrity of biomolecules and hampering cellular metabolism circuits.

Ameliorative effect of diazepam against ethanol-induced mitochondrial disruption in brains of the mice

Toxicology Reports, 2023
Brain oxidative damage and neurodegeneration by ethanol (ETH) are considered as important factors that triggered by oxidative stress. Recently, the abuse of diazepam (DZM) has increased by alcoholism-addicted patients.

Oxidative Damage in Korean Medicine

Antioxidants, 2022
Korean medicine originated in ancient and prehistoric times, as evidenced by the discovery of stone and bone needles in the North Hamgyeong Province, dating back to 3000 BC [...]

Oxidative Stress: What Is It? Can It Be Measured? Where Is It Located? Can It Be Good or Bad? Can It Be Prevented? Can It Be Cured?

Antioxidants, 2022
The meaning, the appropriate usage and the misusage of the terms oxidative stress, oxidative eustress, and oxidative distress have been evaluated. It has been realized that the terms oxidative stress and oxidative damage are often used inappropriately as

Quantification of mitochondrial DNA damage and copy number in circulating blood of patients with systemic sclerosis by a qPCR-based assay, [PDF]

Anais Brasileiros de Dermatologia, 2020
Background: Although not fully understood, oxidative stress has been implicated in the pathogenesis of different autoimmune diseases such as systemic sclerosis.

Interactions between Biliverdin, Oxidative Damage, and Spleen Morphology after Simulated Aggressive Encounters in Veiled Chameleons. [PDF]

PLoS ONE, 2015
Stressors frequently increase oxidative damage--unless organisms simultaneously mount effective antioxidant responses. One putative mitigative mechanism is the use of biliverdin, an antioxidant produced in the spleen during erythrocyte degradation.

Biomarker changes and oxidative damage in living plant cells as new biomonitoring indicators for combined heavy metal stress assessment

Ecological Indicators, 2023
The damage that combined heavy metals cause to plants is a global environmental problem, and it is also harder to detect compared with that from solitary heavy metal.

Evidence of Oxidative Shielding of Offspring in a Wild Mammal

Frontiers in Ecology and Evolution, 2016
Oxidative damage has been proposed as a potential mechanism underlying a life history tradeoff between survival and reproduction. However, evidence that reproduction is associated with increased oxidative damage is equivocal, and some studies have found ...

Oxidative Stress and Oocyte Cryopreservation: Recent Advances in Mitigation Strategies Involving Antioxidants

Cells, 2022
Oocyte cryopreservation is widely used in assisted-reproductive technology and animal production. However, cryopreservation not only induces a massive accumulation of reactive oxygen species (ROS) in oocytes, but also leads to oxidative-stress-inflicted ...

Testing the Effects of DL-Alpha-Tocopherol Supplementation on Oxidative Damage, Total Antioxidant Protection and the Sex-Specific Responses of Reproductive Effort and Lifespan to Dietary Manipulation in Australian Field Crickets (Teleogryllus commodus)

Antioxidants, 2015
The oxidative stress theory predicts that the accumulation of oxidative damage causes aging. More generally, oxidative damage could be a cost of reproduction that reduces survival. Both of these hypotheses have mixed empirical support.
