(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: Diet-induced obesity (DIO) due to a high caloric diet (HCD) predisposes an individual to the development of diabetes and cardiovascular diseases, with high prevalence in young populations. Existing evidence ... -
The effect of green rooibos extract on rat hearts in a pre-diabetic model : an evaluation of the function and mechanisms involved
(Stellenbosch : Stellenbosch University, 2019-03)ENGLISH ABSTRACT: Background— Cardiovascular diseases (CVD) remains the leading cause of death globally, with a rising prevalence of individual risk factors such as obesity and insulin resistance. Furthermore, diabetic ... -
An investigation into the role of ATM protein in mitochondrial defects associated with cardiovascular pathology resulting from insulin resistance
(Stellenbosch : Stellenbosch University, 2019-04)Background: Ataxia-telangiectasia (A-T) is a rare, recessive disorder that develops in the absence of Ataxia-Telangiectasia Mutated protein kinase (ATM). This complex disease is characterised by neurodegeneration, increased ... -
The manipulation of autophagy during early and late reperfusion : the effect on myocardial protection
(Stellenbosch : Stellenbosch University, 2019-03)ENGLISH ABSTRACT: Introduction: Ischemic heart disease, the leading cause of death worldwide, often has devastating effects on myocardial function. ReFestablishment of coronary flow to salvage myocardial cells results in ... -
Basic semen parameters assisted by Computer-Aided sperm analysis (CASA) and their correlations with advanced semen parameters in normozoospermic men with different abstinence periods
(Stellenbosch : Stellenbosch University, 2018-03)Introduction: Affordable basic semen analysis remains a fundamental procedure to be performed routinely during the diagnosis of male infertility. Advanced semen analyses, provide valuable clinical insights in treatment ... -
Contribution of highly active anti-retroviral therapy to the development of non-alcoholic fatty liver disease with concomitant cardiovascular dysfunction in an obese rat model
(Stellenbosch : Stellenbosch University, 2018-03)Introduction: HIV/AIDS mortality is declining due to successful highly active anti-retroviral therapy (HAART). However, obesity, non-alcoholic fatty liver disease (NAFLD) and cardiovascular disease (CVD) in treated ... -
Effect of different substrates on functional performance and kinase activation during reperfusion after ischaemia in hearts from obese insulin resistant rats
(Stellenbosch : Stellenbosch University, 2017-03)ENGLISH ABSTRACT : Obesity is an important risk factor for the development of insulin resistance, the metabolic syndrome and diabetes and has also been implicated as one of the major risk factors for coronary heart disease. ... -
