(University of the Western Cape, 2019)The emergence of virulent and drug-resistant bacterial strains such as methicillin-resistant Staphylococcus aureus (MRSA) is a global public health burden. The World Health Organization (WHO) has placed MRSA and ... -
Effects of graphene oxide nanoparticles on the immune system biomarkers produced by RAW 264.7
(University of the Western Cape, 2019)Graphene oxide (GO) is a single carbon layer, oxygen bearing graphene derivative, containing hydroxyl and carboxyl groups. Graphene oxide nanoparticles (GONPs) are promising nanomaterials for a variety of applications such ... -
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 ... -
An analysis of the morphological and biological properties of a novel human leukocyte- and platelet- rich concentrate
(University of the Western Cape, 2018)Wound healing is a complex process that involves several overlapping and interacting biological pathways. The consequences of delayed or abnormal wound healing may result in tissue formation that has impaired function ... -
Mercury leaching from dental amalgam fillings and its association with urinary zinc
(University of the Western Cape, 2019)Mercury (Hg) is an example of a toxic metal that is not essential for nutrition. It exists in organic and inorganic forms in seafood and vapour from dental amalgam fillings respectively. Elemental mercury (Hg0) from dental ... -
Seasonal differences in semen characteristics and sperm functionality in Tankwa goats
(University of the Western Cape, 2018)Tankwa goats have been free-ranging in the Tankwa Karoo National Park in the Northern Cape for more than 80 years. A genetic study concluded that these feral goats are a unique genetic resource compared to other goat breeds ... -
Evaluating the neuroprotective effects of fermented rooibos herbal tea in Wistar rats exposed to bisphenol-A during gestation and lactation
(University of the Western Cape, 2019)Exposure to endocrine-disrupting chemicals as bisphenol A (BPA) during gestation and early postnatal life is known to disrupt normal developmental processes and alter the body’s endocrine system leading to deleterious ... -
The effect of methamphetamine on the blood-testis barrier
(University of the Western Cape, 2018)Introduction The blood-testis barrier (BTB) is formed by tight junctions between adjacent Sertoli cells. The barrier formed by these tight junction helps to create a specialized environment for spermatogenesis and provide ... -
The association of mercury from dental amalgam with urinary selenium
(University of the Western Cape, 2017)Background: Dental amalgam has been the traditional material for filling cavities in teeth. Mercury (Hg) is a component of dental amalgam, from where it is continuously released and deposited in different tissues, mostly ... -
Medicinal uses of Galenia africana: A study of the antimicrobial, antifungal and anticancer properties
(University of the Western Cape, 2018)Medicinal uses of Galenia africana: A study of the antimicrobial, antifungal and anticancer properties Over the years, microorganisms have become resistant to commonly used antimicrobial agents leading to multidrug resistance. ... -
The role of high-risk human papillomavirus in periocular cancers
(University of the Western Cape, 2018)PURPOSE: High risk human papillomavirus (HR-HPV) is well established as a causative agent of squamous cell carcinoma (SCC) of the orophaynx. HR-HPV has also been reported in periocular cancers and precancers, but controversy ... -
The potential neuroprotective effects of two South African plant extracts in hydrogen peroxide-induced neuronal toxicity
(University of the Western Cape, 2018)Background: Oxidative stress induced by reactive oxygen species has been strongly associated with many neurodegenerative diseases (NDDs) and many medicinal plant-derived products have been reported to exert potent antioxidant ... -
Aspects of the reproduction of male and female African penguins (Spheniscus demersus) with special reference to sperm biology and cryopreservation
(University of the Western Cape, 2018)In the marine environment, penguins have been described as curators and serve a critical role in ecological balance. The African penguin (Spheniscus demersus) has undergone a rapid population decline, mainly due to ... -
Radioprotective effects of rooibos herbal tea on the developing central nervous system of wistar rats
(University of the Western Cape, 2018)Background: Early postnatal radiation exposure from environmental, diagnostic or therapeutic sources is potentially deleterious to the developing nervous system resulting in oxidative stress, structural damage, altered ... -
