Chronic treatment with beta-receptor blockers or angiotensin-converting enzyme (ACE) inhibitors in heart failure can reduce mortality and improve left ventricular function, but the mechanisms involved in their beneficial action remain to be fully defined. Our hypothesis was that these agents prevent the derangement of cardiac energy metabolism. Rats were(More)
Although factor scores are commonly used to interpret the Weschsler Adult Intelligence Scale--Revised (WAIS-R), the WAIS-R factor structure has not been investigated in patients with schizophrenia. We used confirmatory factor analysis (CFA) to examine five latent construct models in 169 males with schizophrenia. The WAIS-R standardization sample (ages(More)
OBJECTIVES The purpose of this study was to examine whether endogenous estrogen deficiency induced by ovariectomy affects chronic left ventricular dysfunction post-myocardial infarction (MI). BACKGROUND Epidemiologic findings suggest that mortality of postmenopausal women is increased after MI, but the underlying mechanisms are unknown. METHODS Rats(More)
The purpose of this study was to define the dose-dependent effects of 17beta-estradiol on coronary flow and cardiac function in isolated rat hearts and to identify the mechanisms involved in its vasodilator action. Hearts from female and male Wistar rats were perfused at constant pressure (100 mm Hg). Stereoisomer specificity and the mechanism of(More)
Validity studies of neuropsychological tests have typically examined individuals with neurological disorders. The present study was designed to investigate the construct validity of neuropsychological measures in patients with schizophrenia. We used Wechsler Adult Intelligence Scale Revised (WAIS-R) factor scores that were generated from the population of(More)
PURPOSE Angiotensin-converting enzyme (ACE) inhibitors show beneficial long-term hemodynamic effects in chronically infarcted hearts. The purpose of this study was to test whether prevention of the deterioration of mechanical function by ACE inhibitors is related to beneficial effects on high-energy phosphate metabolism that is deranged in heart failure.

A recovery-oriented manual was developed for patients with schizophrenia and suicidality. It included psychoeducational information, vignettes, "workbook" sections and was reviewed by experts in suicidology, recovery, patient education, manual development and psychosocial interventions. The revised version was tested in 22 consumers with schizophrenia and a(More)
Recently, short forms of the Wechsler Adult Intelligence Scale-Revised (Wechsler, 1981) have received increasing attention because of their ability to provide estimated IQ scores with substantial time savings (in some cases 85-90% savings). These short forms may have particular utility for individuals with schizophrenia because they require less time to(More)
Dashboards which collect and display real-time streamed data from a variety of rudimentary sensors positioned in the built environment provide an immediate portal for decision-makers to get some sense of their city and environment. These devices are linked to previous renditions of control and management of real time services in cities, particularly(More)
Nicorandil (SG75) is a potent K+-channel activator with an additional nitro moiety. In the present study we investigated the potential mechanisms (K+-channel activation and nitric oxide [NO] release) for the effects of nicorandil on isolated perfused rat hearts during total global ischemia using 31P-nuclear magnetic resonance. After a 10-min control(More)
