The development and implementation of biomarker assays for estrogenic endocrine disruptors
(University of the Western Cape, 2008)Endocrine disrupting chemicals (EDCs) are compounds found in the environment that have the potential to disrupt normal endocrine function. Estrogenic EDCs (e-EDCs) is a subclass of EDCs and is defined as substances ... -
The development of targeting nanosystems for the treatment of glioblastoma and neuroblastoma tumours
(University of the Western Cape, 2022)Chlorotoxin (CTX) peptide selectively targets glioblastoma multiforme (GB) and neuroblastoma (NB) and has excellent blood-brain barrier permeability. Therefore, CTX is a promising targeting molecule for nanoparticle (NP) ... -
Differential toxicity of two murine endothelial cells to ROS duress: Understanding oxidative stress-induced blood-brain barrier dysfunction
(University of the Western Cape, 2020)The blood-brain barrier (BBB) is a critical interface between the blood circulation and brain tissue which performs critical selection of circulating molecules that gain access to the brain tissue. Its unique ability to ... -
The effect of maternal exposure to alcohol and nicotine on pancreas and kidney size, aorta and carotid intima thickness and visceral fat in their children.
(University of Western Cape, 2019)In utero exposure to teratogens, increasing urbanization, rapid nutritional transition from poverty to affluence, adoption of a Western-style diet and physical inactivity have contributed to the growing obesity epidemic ... -
The effect of maternal oral health on pregnancy outcomes
(University of the Western Cape, 2014)Adverse pregnancy outcomes such as preterm birth and low birth weight are major causes of maternal and neonatal morbidity and mortality. Increasing evidence points to an association between periodontal disease and adverse ... -
The effect of nicotine and prostaglandin A2 on the lung cancer cell line NCI-H157
(2009)Lung cancer is the most common fatal cancer in terms of both incidence and mortality in the world. The most important cause of lung cancer is exposure to tobacco smoke through active or passive smoking. Nicotine which is ... -
Effect of tea and herbal infusions on mammalian reproduction and fertility
(University of the Western Cape, 2013)Camellia sinensis (tea) and Aspalathus linearis (rooibos) may improve reproductive function owing to their antioxidant properties. To test this hypothesis, male and female rats were given 2% and 5% green tea (Gt), black ... -
The effects of artificial and natural sweeteners on various physiological systems
(University of the Western Cape, 2011)This study aimed to investigate the effects of commercially available natural (sugar cane molasses, white sugar and brown sugar) and artificial (Canderel, Equal, Natreen, Sweetex, Splenda and Swheet) sweeteners on various ... -
Effects of Fucoidan and Chemotherapeutic agent combinations on Malignant and Non-Malignant breast cell lines
(University of the Western Cape, 2017)Breast cancer is currently one of the most common malignancies in women. Fucoidan (FUC) is a natural polysaccharide with anticancer properties. Despite a number of in vitro and in vivo studies reporting the efficacy of ... -
The effects of green tea, green rooibos and their major flavonoids (EGCG and aspalathin) on testicular cell health in vitro
(University of Western Cape, 2021)The testes play a central role in the male reproductive system, as they represent the sites of male sex steroidogenesis and of spermatogenesis. Leydig cells, located at the testicular interstitium, produce predominantly ... -
Effects of Libyan traditional plants on the reproductive system of male and female rats
(University of the Western cape, 2015)In different parts of the world, medicinal plants have demonstrated a lot of health benefits to mankind and remains an important source for the discovery of new bio-active compounds. Libya is a typical example of a country ... -

The effects of various combinations of different Cdasses of anticancer drugs and tyrosine kinase inhibitors on the human MCF-7 and triple-negative MDA-MB 231 breast carcinoma cell lines
(University of the Western Cape, 2020)Globally, breast cancer is the most common cancer affecting women and it is predicted that in 2030 about 12 million deaths will occur with approximately 21.7 million new cases [2]. Genetic risk factors as well as race and ... -
An evaluation of cancer biomarkers in normal ovarian epithelial cells and ovarian cancer cell lines
(University of the Western Cape, 2019)Introduction: Globally, there are over 190,000 new reported cases of ovarian cancers per annum. This comprises 3% to 4% of all cancers in women. Ovarian cancer is one of the leading causes of deaths in women. Ovarian cancer ... -
Fatty acids as cancer preventive tools in the dietary modulation of altered lipid profiles associated with hepatocarcinogenesis
(University of the Western Cape, 2005)This thesis consists of a brief description on cancer, carcinogenesis, the changes in the type and level of dietary fat available in our diets over time and association with the development of certain diseases. The main ... -
The frequency and characterization of streptococci in aerobic vaginitis (AV) and its association with pregnancy outcomes
(University of the Western Cape, 2014)The aim of the study was to detect the prevalence of AV and its associated bacteria with preterm delivery in the Western Cape, South Africa. Furthermore, it sought particularly to examine and investigate the predictive ... -
Holarrhena floribunda leaves as a potential source of bioactive anticancer compounds
(University of the Western Cape, 2014)Cancer is one of the leading causes of morbidity and mortality in developed and developing nations. It is estimated that 86% of new cases and 64% of death due to cancer are from Africa and 13.1 million deaths are estimated ... -
