Protective effects of Alpha-lipoic acid on MeHg-induced oxidative damage and intracellular Ca(2+) dyshomeostasis in primary cultured neurons.

abstract：:Peroxisome proliferator-activated receptor gamma (PPARγ) is known to be activated via exercise-associated transient increases in oxidative stress. However, the precise mechanism(s) triggering PPARγ activation in monocytes during/following exercise remain to be confirmed. Here, two cohorts of five healthy male individu...
