BACKGROUND This study examines the effects of long-term continuous exposure to light on dopaminergic supersensitivity induced by repeated treatment with haloperidol in rats. METHODS Spontaneous general activity in an open-field (SGA) and stereotyped behavior induced by apomorphine (SB-APO) or amphetamine (SB-AMP) were used as experimental parameters. Rats(More)
1. To determine whether the association between mitral valve prolapse and Graves' disease is related to thyroid function, three groups of individuals were studied: 16 patients with Graves' disease and hyperthyroidism (hyperthyroid: T4 greater than 11.5 micrograms/100 ml), 16 patients with Graves' disease without hyperthyroidism (euthyroid: T4 less than 11.5(More)
Metabolic syndrome is a cluster of metabolic risk factors that is linked to central obesity, elevated blood pressure, insulin resistance (IR), and dyslipidemia, where the renin-angiotensin system (RAS) may provide a link among them. This study aimed to evaluate volume exercise effects comparing low vs. high volume of chronic aerobic exercise on RAS axes in(More)
Antibiotics are potentially a cause of neurotoxicity in dialysis patients, the most common are the beta-lactams as ceftazidime and cefepime, and few cases have been reported after piperacillin/tazobactam use. This report presents a case of a hypertensive and diabetic 67-year-old woman in regular hemodialysis, which previously had a stroke. She was(More)
1. In order to evaluate the mechanism by which beta blockers with intrinsic sympathomimetic activity preserve left ventricular systolic function at rest, 46 patients with coronary artery disease were studied by right and left heart catheterization and left ventriculography. Patients were studied using a double-blind, randomized protocol before and after a(More)
Infection by human T-cell lymphotrophic virus type I (HTLV-I) is associated with a myelopathy known as tropical spastic paraparesis (TSP). The prevalence of HTLV-I infection was found to be high in a pilot study in Bahia, Brazil. In the present study, among patients with myelopathy of unclear etiology, 27% (17/62) were immunoblot reactive to HTLV-I/II(More)
