Oxidative nerve cell death in Alzheimer's disease and stroke: antioxidants as neuroprotective compounds.

abstract：:A novel approach to studying the inter- and intrasubunit communication required for the activity of homodimeric proteins is described. It was developed for the restriction endonuclease EcoRV, but should also be useful for other homodimeric enzymes. Two ecorV genes encoding different EcoRV mutants are coexpressed in th...

abstract：:Oxidative stress has for a long time been associated with cell death, especially classical necrosis, however, its role in other cell death pathways is less clear. Here, we evaluated in a comparative way, the effect of four different reactive oxygen species (ROS) scavengers, N-acetyl-L-cysteine (NAC), α-tocopherol and ...
