Studies of cardiac performance in hypertension have often been restricted to cardiac output determinations, although the latter alone are inadequate for that purpose. To define the range of cardiac performance in hypertension, the response of left ventricular filling pressure to increased workload (static exercise) was determined in 39 subjects--eight normotensive (NT) volunteers, seven patient...

BACKGROUND Falls amongst people with Parkinson's (PwP) result in significant disability and reduced quality of life. There is emerging evidence that exercise-based and physiotherapeutic interventions are of benefit for improving fall risk factors, such as balance. However, the benefit, in terms of preventing falls, is mixed. The development of effective interventions has been identified as the ...

Left ventricular function was assessed in 10 patients with alcoholic cirrhosis and ascites without clinical evidence of heart disease. In the resting state pulmonary wedge pressure (PWP) was normal (average 9.7 mm Hg), cardiac output (CO) was elevated (average 9.7 L/min) and systemic vascular resistance (SVR) was low (average 825 dynes-sec-cm-5). During infusion of angiotensin in a dose suffici...

Stability Analysis and Controller Synthesis for a Class of Piecewise Smooth Systems Behzad Samadi, Ph.D. Concordia Unviersity, 2008 This thesis deals with the analysis and synthesis of piecewise smooth (PWS) systems. In general, PWS systems are nonsmooth systems, which means their vector fields are discontinuous functions of the state vector. Dynamic behavior of nonsmooth systems is richer than...

BACKGROUND People with Parkinson's (PwP) experience frequent and recurrent falls. As these falls may have devastating consequences, there is an urgent need to identify cost-effective interventions with the potential to reduce falls in PwP. The purpose of this economic evaluation is to compare the costs and cost-effectiveness of a targeted exercise programme versus usual care for PwP who were at...

BACKGROUND Public-private partnerships (PPP) could be effective in scaling up services. We estimated cost and cost-effectiveness of different PPP arrangements in the provision of tuberculosis (TB) treatment, and the financing required for the different models from the perspective of the provincial TB programme, provider, and the patient. METHODS Two different models of TB provider partnership...

PHONOLOGICAL MEAN LENGTH OF UTTERANCE AS AN INDICATOR OF TYPICAL AND IMPAIRED PHONOLOGICAL DEVELOPMENT IN CHILDREN ACQUIRING FINNISH Katri Saaristo-Helin University of Helsinki, FIN The aim of this study was to examine the applicability of the Phonological Mean Length of Utterance (pMLU) method to the data of children acquiring Finnish, for both typically developing children and children with a...

A 50-year-old man, who is an active smoker without a previous medical history, was admitted for recent dyspnea (New York Heart Association functional class III) and an episode of exertional syncope. His familial history included the sudden death of his mother at the age of 50. His blood pressure was 123/90 mm Hg; heart rate, 80 beats/min; peripheral oxygen saturation, 95%; and clinical examinat...

Abstract Heavy metals (HMs) are highly toxic water pollutants abundant in industrial wastewater. Herein, a bis[3-(trimethoxysilyl)propyl]amine (BTMSPA) cross-linked multiwalled carbon nanotube (MWCNT) nanomaterial (CQACNT) was synthesized by silanization of MWCNT-OH followed grafting positively charged quaternary ammonium groups (glycidyl trimethyl chloride (GTMAC)) an epoxide ring-opening reac...
