Extensive evidence indicates that current and recently abstinent cocaine abusers compared to drug-naïve controls have decreased grey matter in regions such as the anterior cingulate, lateral prefrontal and insular cortex. Relatively little is known, however, about the persistence of these deficits in long-term abstinence despite the implications this has for recovery and relapse. Optimized voxe...

Previous studies have reported some significant participation by gastric alcohol dehydrogenase (ADH) in alcohol metabolism, similar to that by hepatic ADH. However, the localization of this ADH in the stomach is not yet determined and there has been no study on the localization of ADH in the stomach of alcoholics before and after abstinence from alcohol. The aim of the present study was to reve...
