The purpose of this study was to elucidate the etiological pathways towards substance use and risky sexual behavior in female adolescent substance abusers. The study had three aims: (1) to determine the relations between behavioral dysregulation, negative affectivity, and childhood victimization with substance use and risky sexual behavior, (2) to determine(More)
OBJECTIVE To determine whether deficient executive cognitive functioning (ECF) in association with high behavioral activity level comprise components of the liability to substance abuse. METHOD A high-risk (HR) group having fathers with a lifetime DSM-III-R diagnosis of a psychoactive substance use disorder was compared with a low-average-risk (LAR) group(More)
The aim of the present research is to investigate the effects of vasonatrin peptide (VNP) on hypoxia-induced proliferation and collagen synthesis in pulmonary artery smooth muscle cells (PASMCs). Smooth muscle cells isolated from rat pulmonary artery were cultured and used at passages 3-5. Cell proliferation and collagen synthesis were evaluated by cell(More)
Alcoholic cirrhotics (n = 49), nonalcoholic cirrhotics (n = 42), and normal controls (n = 50) were compared on measures of isokinetic muscle strength and neuropsychological capacity. Alcoholic cirrhotics were deficient on measures of eccentric and concentric muscle movements, compared with normal controls but were not different from nonalcoholic cirrhotics.(More)
This study had three aims: (1) to determine the relations between behavioral dysregulation, negative affectivity, and familial impairment with violence and suicidality (i.e., severity of ideation and attempts) in a sample of adolescent females with a psychoactive substance use disorder and controls; (2) to determine whether these relations are mediated by(More)
AIM To investigate the relaxation effect and underlying mechanism of U50,488H (a selective kappa-opioid receptor agonist) in pulmonary artery in the rat. METHODS Isolated pulmonary artery ring was perfused and the tension of the vessel was measured. RESULTS U50,488H relaxed the pulmonary artery ring in a dose-dependent manner and the effect was(More)
In this study, we determined the effect of U50,488H (a selective kappa-opioid receptor agonist) on pulmonary artery in rats and investigated its prevention and treatment effects on hypoxic pulmonary hypertension (HPH). Isolated pulmonary arterial rings were superfused and the tension of the vessel was measured. The model of HPH was developed and indexes for(More)
Abnormal proliferation of vascular smooth muscle cells (VSMCs) is known to be a key event in the development of atherosclerosis and restenosis. The present study examined the effect of a novel synthetic natriuretic peptide, vasonatrin peptide (VNP), on norepinephrine (NE)-induced proliferation of VSMCs from coronary bypass vessels. Human VSMCs were isolated(More)
OBJECTIVE To test the hypothesis that low socioeconomic status (SES), a disturbed parent-daughter relationship, early sexual development, and antisocial behavior are risk factors in adolescent females affiliating with adult male sexual partners. To determine whether the relation between these risk factors and affiliating with adult male sexual partners is(More)
Intensity of isometric muscle contractions was measured in alcoholic subjects with cirrhosis (N = 42), nonalcoholic subjects with cirrhosis (N = 33), and normal controls (N = 31). Muscle strength and endurance were comparable in the alcoholic and nonalcoholic cirrhotic subjects for all variables. Both cirrhotic groups were inferior to normal controls for(More)
