Abstract:
:We investigated the effects of radio frequency electromagnetic fields on brain physiology. Twenty-four healthy young men were exposed for 30 min to pulse-modulated or continuous-wave radio frequency electromagnetic fields (900 MHz; peak specific absorption rate 1 W/kg), or sham exposed. During exposure, participants performed cognitive tasks. Waking electroencephalogram was recorded during baseline, immediately after, and 30 and 60 min after exposure. Pulse-modulated radio frequency electromagnetic field exposure reduced reaction speed and increased accuracy in a working-memory task. It also increased spectral power in the waking electroencephalogram in the 10.5-11 Hz range 30 min after exposure. No effects were observed for continuous-wave radio frequency electromagnetic fields. These findings provide further evidence for a nonthermal biological effect of pulsed radio frequency electromagnetic fields.

NEUROREPORT文献大全abstract::Sirtuin 2 (SIRT2) is a member of the sirtuin family. Previous studies have suggested that SIRT2 mediates the cell death in models of Parkinson's disease and Huntington's disease. However, the role of SIRT2 in oxidative stress-induced cell death has remained unclear. In this study, we investigated the roles of SIRT2 in...
