Low density lipoprotein cytotoxicity induced by free radical peroxidation of lipid.

Journal of Lipid Research, 1983
Low density lipoprotein (LDL) has been reported to be injurious or toxic to cells in vitro. This injurious effect is, in some instances, due to oxidation of the lipid moiety of the lipoprotein.

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 activity of propolis

Redox Report, 2002
We investigated the radical scavenging activity of propolis by ESR spectroscopy using spin trapping method. In addition, we examined the influence of a diet of 2% propolis on mice under oxidative stress. At low concentrations, the methanolic extract of propolis exhibited strong scavenging activity in vitro towards both the superoxide anion radical ...

Scavenging Effects of Dexrazoxane on Free Radicals [PDF]

Journal of Clinical Biochemistry and Nutrition, 2010
Dexrazoxane (ICRF-187) has been clinically used to reduce doxorubicin-induced cardiotoxicity for more than 20 years. It has been proposed that dexrazoxane may act through its rings-opened hydrolysis product ADR-925, which can either remove iron from the iron-doxorubicin complex or bind to free iron, thus preventing iron-based oxygen radical formation ...
