The objective of the present study was to examine allelic prevalence of the D2 dopamine receptor (DRD2) gene in male cocaine-dependent (CD) Caucasian (non-Hispanic) subjects and to determine the relationship of DRD2 alleles to family history and selected behavioral measures. The prevalence of the A1 allele in CD subjects (n = 53) was 50.9%. It was(More)
Event-related potentials were recorded during a visual, continuous performance task from 36 boys before use of alcohol or other drugs began. The boys were sons of 13 recovering alcoholics who themselves had a family history of alcoholism, 11 nonalcoholics with a family history of alcoholism, and 12 nonalcoholics with no family history of alcoholism. Four(More)
Previous studies have shown an association of the 3' Taq1 A1 allele of the D2 dopamine receptor (DRD2) gene with severe alcoholism. The recent demonstration of a new polymorphism located closer to the regulatory regions of this gene, permits an associational analysis of these 5' Taq1 B alleles with alcoholism and a comparison with the 3' Taq1 A alleles.(More)
The prevalence of TaqI A alleles of the D2 dopamine receptor (DRD2) gene was examined in two subgroups of medically ill nonalcoholics (more prevalent and less prevalent substance users, MPSU and LPSU, respectively) and in two subgroups of medically ill alcoholics (more severe and less severe alcoholics, MSA and LSA, respectively). The prevalence of the A1(More)
We have sequenced the complete genomes of 72 individuals affected with early-onset familial Alzheimer's disease caused by an autosomal dominant, highly penetrant mutation in the presenilin-1 (PSEN1) gene, and performed genome-wide association testing to identify variants that modify age at onset (AAO) of Alzheimer's disease. Our analysis identified a(More)
In a blinded study, 159 subjects composed of nonalcoholics (N = 43), less severe alcoholics (N = 44), severe alcoholics (N = 52) and young children of alcoholics (CoAs, N = 20) were studied for their allelic association with the D2 dopamine receptor (D2DR) gene utilizing peripheral lymphocytes as the DNA source. The combined alcoholic group compared to the(More)
The efficacy, safety and disposition of olsalazine was assessed in patients with left-sided ulcerative colitis or proctitis in a double-blind placebo controlled trial. Thirty patients with a mild-to-moderate attack of ulcerative colitis were randomly allocated to olsalazine capsules, 1 g b.d., or placebo for 6 weeks. Good clinical response was found in six(More)
There is now growing evidence that the less prevalent allele (A1) of the D2 dopamine receptor (DRD2) gene is strongly associated with severe alcoholism. Similarly, subjects who abuse illegal drugs or who are obese also show a significantly higher prevalence of the A1 DRD2 allele compared to controls. Moreover, cigarette smokers, both past and current,(More)
A histological study was made of the carotid bodies of man and various animal species from low and high altitudes. The animals studied were the alpaca, llama, cattle, guinea-pig, rabbit, dog, rat and man. As well as a qualitative microscopic study, a differential cell count was carried out to determine the percentage of the light and dark variants of chief(More)
