Reactive Oxygen Species (ROS): A Review [PDF]
AbstractIn the late 1950's free radicals and antioxidants were almost unheard of in the clinical and biological sciences but chemists had known about them for years in the context of radiation, polymer and combustion technology. Daniel Gilbert, Rebeca Gerschman and their colleagues related the toxic effects of elevated oxygen levels on aerobes to those

Detection of reactive oxygen and nitrogen species by electron paramagnetic resonance (EPR) technique [PDF]
During the last decade there has been growing interest in physical-chemical oxidation processes and the behavior of free radicals in living systems. Radicals are known as intermediate species in a variety of biochemical reactions.

Dietary Antioxidant An Indispensible Nutrient
Free radicals prevail as atoms, molecules or unpaired electrons being extremely reactive as well as unstable1. They can lead to chemical reactions alongside different molecules.

Highly efficient optogenetic cell ablation in C. elegans using membrane-targeted miniSOG. [PDF]
The genetically encoded photosensitizer miniSOG (mini Singlet Oxygen Generator) can be used to kill cells in C. elegans. miniSOG generates the reactive oxygen species (ROS) singlet oxygen after illumination with blue light.

What Did We Accomplish in Fighting Radical Species in Human Health?
Maintaining the physiological level of reactive oxygen species (ROS) and reactive nitrogen species (RNS) in the body is highly important in the fight against radical species in the context of human health [...]

Reactive Oxygen Species (ROS), Intimal Thickening, and Subclinical Atherosclerotic Disease
Arteriosclerosis causes significant morbidity and mortality worldwide. Central to this process is the development of subclinical non-atherosclerotic intimal lesions before the appearance of pathologic intimal thickening and advanced atherosclerotic ...

Glutathione Metabolism in Renal Cell Carcinoma Progression and Implications for Therapies [PDF]
A significantly increased level of the reactive oxygen species (ROS) scavenger glutathione (GSH) has been identified as a hallmark of renal cell carcinoma (RCC). The proposed mechanism for increased GSH levels is to counteract damaging ROS to sustain the

Reactive Oxygen Species (ROS) and Nucleic Acid Modifications during Seed Dormancy
The seed is the propagule of higher plants and allows its dissemination and the survival of the species. Seed dormancy prevents premature germination under favourable conditions.

Reactive oxygen species (ROS): Beneficial companions of plants’ developmental processes
Reactive oxygen species (ROS) are continuously generated inevitably in the redox reactions of plants, including respiration and photosynthesis. In earlier studies, ROS were considered as toxic by-products of aerobic pathways of the metabolism.
