Acute effect of small doses of alcohol on the NSD parameters (normalized slope descriptors) of human EEG.

abstract：RATIONALE:Individual differences in the rate of nicotine metabolism (RNM) could be related to dependence and success in stopping smoking. A range of studies have examined RNM measured by the ratio of trans-3'-hydroxycotinine and cotinine in body fluids (the ratio). A systematic review of this literature is needed to dr...
