There is strong evidence for genetic influences on personality traits. Interest in one such gene, the dopamine D4 receptor (DRD4) grew after an exon III polymorphism was associated with Novelty Seeking and related measures of Extraversion. However, the findings were not confirmed in later studies. Recently, a -521C/T single nucleotide polymorphism (SNP)(More)
Although strong positive association between alcoholism and depression is a common epidemiological observance, the causal relationship and the neurobiological substrates of such observations are far from clear. We have reported that chronic daily exposure to a relatively high dose of alcohol in rats can induce or exacerbate an already existing(More)
BACKGROUND Chronic substance abuse has been associated with decrements in the processing and expression of language. The present study utilized the N400 event-related electroencephalographic potential to index semantic processing in 133 adults with (n=49) or without (n=84) a history of alcohol and/or cocaine dependence. The contributions of age, gender, and(More)
Strong positive correlation between depression and alcoholism is evident in epidemiological reports. However, a causal relationship for this co-morbidity has not been established. We have observed that chronic daily exposure to a relatively high dose of alcohol can induce depressive-like behavior in rats and that pretreatment with nomifensine or imipramine(More)
A consecutive sample of 63 adventitiously blinded American military veterans in a interdisciplinary inpatient rehabilitation program participated in this study examining the relation of hope to self-reported functional ability level. Scores from a modified oral administration of the Hope Scale and the Millon Behavioral Health Inventory basic coping styles(More)
It is well established that combination of heavy drinking and smoking has severe health consequences. However, at relatively low concentrations, both alcohol and nicotine may have beneficial effects including neuroprotection. Thus, protective effects of low alcohol concentration against beta-amyloid-induced toxicity in organotypic hippocampal slices and(More)
Both alcohol and nicotine have been shown to possess antinociceptive or analgesic effects. An additive or synergistic antinociceptive effect induced by simultaneous administration of alcohol and nicotine could further contribute to their co-abuse. In this study, we sought to evaluate the antinociceptive effects of various combinations of ethanol and(More)
Alcoholism is associated with a higher incidence of smoking. In addition to the stimulatory effects of both ethanol and nicotine on the mesolimbic reward pathway, nicotine's ability to counteract some of the adverse effects of ethanol (e.g. ataxia) may be a powerful incentive for alcohol consumers to increase their tobacco (nicotine) intake. The cerebellum(More)
BACKGROUND Beliefs, attitudes, and preferences about the risk and benefits of genetic testing are important determinants of willingness to undergo testing. AIMS The purpose of this study was to evaluate the perceived importance of genetic testing for alcohol dependence compared with other multifactorial diseases among African Americans.
