Ratio of stroke volume (SV, M-mode echocardiography) to pulse pressure (PP) has been proposed as an estimate of total arterial compliance and has been shown to be related to body size, age, and heart rate in normal adults. SV/PP was estimated in 294 hypertensive patients (98 women) as a raw value by use of SV/body surface area (SVi) and by the ratio of SV/PP to the value predicted by a previous...

Reflection and transmission of plane waves between two initially stressed thermoelastic half-spaces with orthotropic type of anisotropy is studied. Incidence of a SV-type wave from the lower half-space is considered and the amplitude ratios of the reflected and transmitted SV-wave, P-wave and thermal wave are obtained by using appropriate boundary conditions. Numerical computation for a particu...

Background: Sodium valproate (SV) has been approved for migraine prophylaxis and its intravenous form is used to treat acute migraine attacks. We compared the efficacy and safety of intravenous SV and subcutaneous Sumatriptan in managing acute migraine attacks. Methods: This double-blind randomized clinical trial divided 90 patients into two groups: one group received 400 mg of intravenous SV a...

conclusions in our patients, the ra grafts had an acceptable patency rate in 2 to 5 years’ follow-up. although the sv grafts had a relatively higher patency rate than ra grafts in our asymptomatic patients, the patency rates in ra and sv grafts were close to each other. the ra graft function was poor in the patients with a higher number of risk factors and in the females. background patency of ...

SV-rings are commutative rings whose factor rings modulo prime ideals are valuation rings. SV-rings occur most naturally in connection with partially ordered rings (= porings) and have been studied only in this context so far. The present note first develops the theory of SV-rings systematically, without assuming the presence of a partial order. Particular attention is paid to the question of a...

OBJECTIVE To investigate liver lobe volumes and the ratios of liver lobe volumes to spleen volume measured with magnetic resonance imaging (MRI) for quantitatively monitoring and staging liver fibrosis. METHODS Animal study was approved by Institutional Animal Care and Use Committee. Sixteen minipigs were prospectively used to model liver fibrosis, and underwent abdominal gadolinium-enhanced ...

BACKGROUND The resistance of internal mammary artery (IMA) toward thrombotic occlusion and accelerated atherosclerosis is not well understood. This study analyzed gene expression profiles of vascular smooth muscle cells (VSMCs) from IMA versus saphenous vein (SV). METHODS AND RESULTS 54'675 probe sets were examined by Affymetrix microarrays. Thirty-one genes belonged to the coagulation system...

OBJECTIVES There is a lack of information on sexual violence (SV) among men who have sex with men and transgendered individuals (MSM-T) in southern India. As SV has been associated with HIV vulnerability, this study examined health related behaviours and practices associated with SV among MSM-T. DESIGN Data were from cross-sectional surveys from four districts in Karnataka, India. METHODS M...
