Free radical formation and subsequent lipid peroxidation may participate in the pathogenesis of tissue injury, including the brain injury induced by hypoxia or trauma and cardiac injury arising from ischemia and reperfusion. However, the exact cellular mechanisms by which the initial oxidative insult leads to the ultimate tissue damage are not known. A(More)
Paraquat induced the SOS response in Escherichia coli. This was measured in terms of acquired resistance towards UV lethality in a wild-type strain and in terms of appearance of beta-galactosidase activity in a din::Mu d(Ap lac) fusion strain. However measured, the induction of the SOS response by paraquat was entirely dioxygen-dependent; whereas induction(More)
