(Stellenbosch : Stellenbosch University, 2022-04)Introduction: Prenatal cigarette exposure (PCE) and prenatal alcohol exposure (PAE) are associated with obstetric complications such as intrauterine growth restriction. This could lead to small for gestational age (SGA) ... -
A mechanistic study on the mu-opioid receptor in human spermatozoa
(Stellenbosch : Stellenbosch University, 2021-12)Background: Infertility remains a complex and often unexplained phenomenon. The effect of opioids on male reproductive parameters is best understood by the suppression of the hypothalamic- pituitary-gonadal (HPG) axis. ... -
Cardio-metabolic risk profile of people living with HIV: Is retinal microvascular geometric morphology a marker of effect?
(Stellenbosch : Stellenbosch University, 2022-04)Background and Aim Cardiovascular disease in people living with HIV has become of great concern. HI-viral factors, ART-toxicity and HIV/ART-associated cardiometabolic adverse effects have been implicated in the development ... -
Factors that affect the adipocytic differentiation of adipose-derived mesenchymal stem cells
(Stellenbosch : Stellenbosch University, 2022-04)Background – Increased adiposity, particularly the accumulation of visceral adipose tissue is linked to the onset and progression of the metabolic syndrome. Despite the known pathogenicity of excessive visceral fat ... -
The effect of an aspalathin-rich rooibos extract on inflammatory crosstalk between adipocytes and muscle cells
(Stellenbosch : Stellenbosch University, 2021, 2021-12)ENGLISH ABSTRACT: The skeletal muscle not only plays a role in maintaining posture and generating force (contraction), but also is a dynamic metabolically active tissue that plays a central role in the regulation of ... -
Modeling changes in resting heart rate and its relationship to all-cause mortality in humans
(Stellenbosch : Stellenbosch University, 2021-03)Background Resting heart rate (RHR) is an easily measurable proxy of cardiovascular and general health. Extensive cohort studies have indicated that a higher RHR among individuals, results in an increased risk of all-cause ... -

Effect of rooibos treatment on inflammatory and oxidative stress genes in in vitro and in vivo models of NAFLD
(Stellenbosch : Stellenbosch University, 2021-03)ENGLISH ABSTRACT: Background: Non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) have been associated with the rise in metabolic diseases. Inflammation and oxidative stress are key mediators ... -
Antioxidant supplementation as protective strategy against stem cell impairment in Type 2 Diabetes
(Stellenbosch : Stellenbosch University, 2021-03)ENGLISH ABSTRACT: Type 2 Diabetes Mellitus (T2DM) is a global epidemic. It is a complex disorder that leads to cellular dysfunction and the development of co-morbidities. The underlying pathologic microenvironment in T2DM, ... -
A potential link between adiposity and the heart: Investigating a posttranscriptional mechanism of cardiac ATM protein regulation in obesity
