Electron Transfer Induced Photofragmentation as a Route to Free Radicals

This paper describes the use of electron transfer induced photofragmentation reactions for the generation of free radicals. Two general reactions (eqns. 1, 2) are presented. Equation I

THE DECAY OF FREE RADICALS iN POLYMER

Kinetic laws and particularities of migration mechanisms of free valence in the processes of decay of free radicals in polymers are dealt with. The basic examples correspond to the results for polyethylene and polymethyl methacrylate. The kinetics of the decay reactions are discussed from the viewpoint of Waite's cage diffusion theory and Levedev's model. From the kinetic data of various author...

P-216: Dual Targeting of TNF-? and Free Radicals Toxic Stress as A Promising Strategy to Manage Experimental Polycystic Ovary

The Simplest Free Radicals

INTRODUCTION Every lexicographer knows that the meaning of a word is time dependent, and, in favour of the argument that it is also dependent on latitude and longitude, the perverse amonst us would cite Oscar Wilde's dictum, "England and America are two countries separated by a common language". Certainly the word radical has changed its meaning for chemits who originally thought of it as part ...

Free radicals in carcinogenesis.

It has become clear since the workshop that free radicals are implicated not only in the promotion phase of carcinogenesis but during initiation as well. Since the workshop, however, despite intriguing trapping studies with Superoxide disimilase. catalase, and Cu-DIPS [copper(II)(3,5-diisopropylsalicylate)2] and generation of OJ using xanthine oxidase, little substantive evidence has been obtai...
