(Stellenbosch : University of Stellenbosch, 2010-12)ENGLISH ABSTRACT: Sperm morphology remains an important parameter in the prediction of fertility, both in vivo and in vitro. However, there remains a considerable level of concern surrounding the true potential of this ... -
A critical analysis of mitochondrial functioning and associated proteins in obesity-related cardiomyopathy
(Stellenbosch : Stellenbosch University, 2013-03)ENGLISH ABSTRACT: INTRODUCTION: The mechanism behind obesity-related cardiomyopathies is at present not completely known, however, cardiac insulin resistance has been implicated as one of the main arbitrators of obesity-related ... -
A diffusion tensor imaging study in HIV patients with and without apathy
(Stellenbosch : University of Stellenbosch, 2010-12)ENGLISH ABSTRACT: HIV/AIDS is a global epidemic that accounts for a large percentage of the mortality in South Africa every year. Since the implementation of anti-retroviral treatment, HIV positive individuals have been ... -
The effect of 5'-aminoimidazole-4-carboxamide ribonucleoside (AICAR) and 5'-aminoimidazole-4-carboxamide-ribonucleoside-phosphate (ZMP) on myocardial glucose uptake
(Stellenbosch : Stellenbosch University, 2005-03)ENGLISH ABSTRACT: Introduction: Exercise increases skeletal muscle glucose uptake via AMP-activated protein kinase (AMPK) activation and GLUT4 translocation from cytosol to cell membrane. It also promotes glucose ... -
Effect of Aspalathus linearis supplementation, during anti-retroviral treatment, on the heart and aortas of male Wistar rats and the effects of drinking rooibos on the cardiovascular profile of patients on ART.
(Stellenbosch : Stellenbosch University, 2017-03)ENGLISH ABSTRACT : Introduction Improved survival rates in the human immunodeficiency virus (HIV) population, due to the use of antiretroviral therapy (ART), are associated with increased risk for cardiovascular disease ... -

(Stellenbosch : Stellenbosch University, 2018-03)Introduction: Obesity is an excessive fat accumulation in the body, known to be a significant precursor to insulin resistance and type 2 diabetes. Complications associated with obesity can contribute to the development of ... -
The effect of CPT-1 inhibition on myocardial function and resistance to ischemia/reperfusion injury in a rodent model of the metabolic syndrome
(Stellenbosch : University of Stellenbosch, 2010-12)ENGLISH ABSTRACT: Background: Obesity is associated with dyslipidemia, insulin resistance and glucose intolerance and together these components characterise the metabolic syndrome (Dandona et al. 2005). In the state of ... -
The effect of hypoxia on nitric oxide and endothelial nitric oxide synthase in the whole heart and isolated cardiac cells: the role of the PI3–K / PKB pathway as a possible mediator.
(Stellenbosch : University of Stellenbosch, 2009-03)In the heart, endothelial nitric oxide synthase (eNOS) is regarded as the most important constitutively expressed enzymatic source of nitric oxide (NO), a major cardiac signalling molecule. On the whole, NO is regarded ... -
