BACKGROUND Ukraine has experienced an increase in injection drug use since the 1990s. An increase in HIV and hepatitis C virus infections has followed, but not measures of prevalence and risk factors. The purposes of this study are to estimate the prevalence of HIV, HCV, and co-infection among injection drug users (IDUs) in central Ukraine and to describe risk factors for HIV and HCV. METHODS...
The metabolic pathways of clozapine (CZ, Clozaril (Novartis Pharmaceuticals Corporation, East Hanover, NJ), 8-chloro-11-(4-methyl-1-piperazinyl)-5H-dibenzo [b,e][1,4]diazepine, a tricyclic benzodiazepine neuroleptic which has a reduced risk of unwanted neurological effects, were determined in normal male volunteers after a single oral dose of 50 mg of [14C]CZ. There was no radio-activity in exh...
Uptake by the dopamine transporter (DAT) is the primary pathway for the clearance of extracellular dopamine (DA) and consequently for regulating the magnitude and duration of dopaminergic signaling. Amphetamine (AMPH) has been shown to decrease simultaneously DAT cell-surface expression and [(3)H]DA uptake. We have shown that insulin and its subsequent signaling through the phosphatidylinositol...
Drugs that antagonize D2-like receptors are effective antipsychotics, but the debilitating movement disorder side effects associated with these drugs cannot be dissociated from dopamine receptor blockade. The "atypical" antipsychotics have a lower propensity to cause extrapyramidal symptoms (EPS), but the molecular basis for this is not fully understood nor is the impact of inverse agonism upon...
The compound 2-amino-4-0~0-6-acety1-7,8-dihydro-3H,9H-pyrimido[4,5-b]-[1,4]diazepine (pyrimidodiazepine or PDA, for short) is a precursor of the red eye pigments called the drosopterins in Drosophila melanogaster. The precursor of PDA is 2-amino-4oxo-6-(~-erythro-l’,2‘,3’-trihydroxypropyl)-7,8-dihydropteridine triphosphate (dihydroneopterin triphosphate or Hz-NTP). The synthesis of of PDA from ...
Systematically synthesized derivatives of ML-9, 1-(5-chloronaphthalenesulfonyl)-1H-hexahydro-1,4-diazepine, were found to inhibit both Ca2+-calmodulin-dependent and -independent smooth muscle myosin light chain kinases with a similar concentration dependence, and their inhibitions were of the competitive type with respect to ATP. Moreover, ML-9 as well as ATP or ADP exhibited an effective prote...
