BACKGROUND Recent studies have reported a high comorbidity between posttraumatic stress disorder (PTSD) and psychotic symptoms, and it has been hypothesized that PTSD with comorbid psychosis is a severe form of PTSD. Few studies have examined the neurobiology of PTSD with comorbid psychosis. If PTSD with secondary psychotic symptoms (PTSD-SP) is a severe(More)
A national probability survey of human immunodeficiency virus (HIV)-related risk factors among the general heterosexual population, the National AIDS (acquired immunodeficiency syndrome) Behavioral Surveys, has obtained data from 10,630 respondents. Data are presented on the prevalence of HIV-related risks in the general heterosexual population, on the(More)
The adenosine agonists 5'-N-ethylcarboxamideadenosine (NECA), 2-chloroadenosine (2-CLA), N6-cyclohexyladenosine (CHA), N6-cyclopentyladenosine (CPA), 2-(phenylamino)adenosine (CV-1808) and R and S isomers of N6-phenylisopropyladenosine (R-PIA and S-PIA) decreased spontaneous locomotor activity in mice and, except for CPA, did so at doses that did not impair(More)
This article describes the association between drug and alcohol use during sexual activity and high-risk sex for AIDS. Data to test this association are drawn from a prospective study of the behavioral changes made by gay men in San Francisco in response to the AIDS epidemic. Findings drawn from the May, 1984 and May 1985 waves of data collection are(More)
Administration of B-HT 920 alone produced weak stereotypy in a small percentage (4-8%) of rats. In contrast, after combined administration of idazoxane and B-HT 920, stereotyped behaviors (sniffing and licking) were consistently produced in all rats. The appearance of stereotypy after combined treatment with yohimbine and B-HT 920 was inversely related to(More)
Lower hemoglobin is associated with cognitive impairment and Alzheimer's disease (AD). Since brain iron homeostasis is perturbed in AD, we investigated whether this is peripherally reflected in the hematological and related blood chemistry values from the Australian Imaging Biomarker and Lifestyle (AIBL) study (a community-based, cross-sectional cohort(More)
The pharmacology of PD 144418 (1-propyl-5-(3-p-tolyl-isoxazol-5-yl)-1,2,3,6-tetrahydropyridine) was characterized using neurochemical, biochemical and behavioral techniques. For sigma (sigma 1 and sigma 2 respectively) sites, PD 144418 affinities were determined using whole guinea pig brain membranes with [3H](+)-pentazocine and neuroblastoma x glioma cell(More)
CI-1007 has been described in receptor binding and biochemical tests as a dopamine (DA) partial agonist that exhibits DA autoreceptor agonist effects. The present studies describe the profile of CI-1007 in electrophysiological and behavioral tests. CI-1007 inhibited the firing of substantia nigra DA neurons with intrinsic DA agonist activity that was less(More)
PD 158771 has been described in receptor binding and biochemical tests as a partial agonist at dopamine (DA) D2 and D3 receptors as well as an agonist at serotonin (5-HT)(1A) receptors. The present studies describe the profile of PD 158771 in rodent and primate behavioral tests. PD 158771 reduced spontaneous locomotor activity in mice (ED(50)=0.38 mg/kg,(More)
OBJECTIVE A family history approach was used to determine if posttraumatic stress disorder (PTSD) with secondary psychotic symptoms was associated with a familial vulnerability to schizophrenia and other psychoses. METHOD Family history methods were used to compare rates of familial psychopathology in the first-degree relatives of three proband groups: 1)(More)
