In 43 cases with symptomatic cerebral vasospasm after aneurysmal subarachnoid hemorrhage treated by intraarterial infusion of papaverine (IAP), we studied cerebral hemodynamics by measuring cerebral circulation time (CCT) using digital subtraction angiogram. CCT on the middle cerebral artery site was defined as CCT-LAV and on the anterior cerebral artery side as CCT-MAV. In the CCT-LAV, two pha...
Objective: The aim of this study was to predict mid-term left atrial reverse remodeling after mitral valve surgery. Patients and Methods: Echocardiographic data was obtained preoperatively and at follow-up from 105 patients who underwent mitral valve surgery. Left atrial volume (LAV) was decreased by >30% from baseline in 43 patients (group A), but not in 62 patients (group B). Results: Patient...
Dengue is a mosquito-borne infection caused by four distinct serotypes of dengue virus, each appearing cyclically in the tropics and subtropics along the equator. Although vaccines are currently under development, none are available to the general population. One of the main impediments to the successful advancement of these vaccines is the lack of well-defined immune correlates of protection. ...
A study of 304 sexually active homosexual men, most of whom had multiple casual partners, showed that receptive anogenital intercourse, independent of anal bleeding, was the only risk factor for HTLV-III/LAV transmission. There was no evidence that HTLV-III/LAV infection, measured by seropositivity, was transmitted by oroanal or orogenital routes, or that insertive penile intercourse constitute...
Simian T-lymphotropic retroviruses with structural, antigenic, and cytopathic features similar to the etiologic agent of human acquired immunodeficiency syndrome, human T-lymphotropic virus type III/lymphadenopathy-associated virus (HTLV-III/LAV), have been isolated from a variety of primate species including African green monkeys (STLV-IIIAGM). This report describes nucleic acid cross-reactivi...
Noise and whole-body vibration measurements were made in the following Canadian Forces vehicles: LAV III, Bison and M113A2 ADATS (air defence anti-tank system). Measurements were made at different crew positions while the vehicles were driven at different speeds over rough terrain and paved roads. The participants completed a questionnaire at the end of each measurement session on their reactio...
