Oxygen levels do not determine radiation survival of breast cancer stem cells. [PDF]
PLoS ONE, 2012 For more than a century oxygen has been known to be one of the most powerful radiosensitizers. However, despite decades of preclinical and clinical research aimed at overcoming tumor hypoxia, little clinical progress has been made so far.

Photoinduced Electron-transfer Reaction of Pentafluoroiodobenzene with Alkenes
Molecules, 1997 Irradiation of pentafluoroiodobenzene and alkenes gave the corresponding adducts. The presence of single electron-transfer scavengers, (p-dinitrobenzene and t-Bu2NO) and the free radical inhibitor (hydroquinone) suppressed the reaction.

Free radical scavenging properties of pyrimidine derivatives [PDF]
Organic and Medicinal Chemistry Letters, 2012 Free radicals are well known for playing a dual role in our body- deleterious as well as beneficial. It includes a metabolic pathway for its generation. Oxidative stress in our body occurs due to excessive generation of free radicals and reduced level of antioxidants, but at low concentrations, these radicals help to perform normal physiological ...

Role of cytoglobin, a novel radical scavenger, in stellate cell activation and hepatic fibrosis [PDF]
Clinical and Molecular Hepatology, 2020 Cytoglobin (Cygb), a stellate cell-specific globin, has recently drawn attention due to its association with liver fibrosis. In the livers of both humans and rodents, Cygb is expressed only in stellate cells and can be utilized as a marker to distinguish
