The relationship between "fertilizaiton environment" and structure and physiology of selected Anuran Spermatozoa
(University of the Western Cape, 1993)The propagation of species and modes of fertilization of higher vertebrates are aspects which have been extensively researched. Studies on the spermatology of lower vertebrates have not received the same attention. Anurans ... -
A molecular investigation of the prevalence of suspected periodontopathogens and their association with preterm birth
(University of the Western Cape, 2010)More than 20 million infants in the world (15.5 % of all births) are born with low birth weight. Ninety-five % of them are in developing countries. oral colonization of gram-negative anaerobes has been implicated as a risk ... -
Investigation of the in vitro antidiabetic and neuroprotective effects of selected Helichrysum species against high monosaccharide-induced toxicity
(University of the Western Cape, 2022)Chronic hyperglycaemia (glucotoxicity), a common complication in diabetes mellitus (DM), is known to cause cognitive decline in some of these patients, often affecting their overall quality of life. Some medicinal plants ... -
Proteome profiling as tool to determine the effectiveness of traditional Africa therapies for Type 2 diabetes mellitus
(University of the Western Cape, 2022)Type 2 diabetes mellitus (T2DM) involves multiple organ dysfunction accompanied by a chronic inflammatory state and oxidative stress resulting from a combination of factors such as hyperglycaemia and dyslipidaemia. Although ... -

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) ... -
Sperm function in different human sperm subpopulations
(University of the Western Cape, 2022)Human semen contains a heterogenous population of spermatozoa of which only a certain fraction is physiologically suitable for fertilization. Functional characteristics of these subpopulations and sperm separation ... -
The paracrine effect of normoxic and hypoxic cancer secretions on blood-brain barrier endothelial cells
(University of the Western Cape, 2022)Cancer is the most common leading cause of death worldwide. Glioblastoma and breast cancer are the most aggressive solid tumour. The survival rate of these tumours depends on their ability to progress and spread. These ... -
A retrospective analysis of semen samples and reproductive hormones in Africa and the middle east
(University of Western Cape, 2022)Semen analysis is the cornerstone for the investigation of male infertility. Semen quality can be influenced by geographical location, age, ejaculatory abstinence, and season. In 2010, the WHO published criteria for human ... -
Investigating novel aspects of the blood-brain barrier using high resolution electron microscopy
(University of the Western Cape, 2022)The blood-brain barrier (BBB) is a restrictive interface located between the blood circulation and the central nervous system (CNS), regulating the homeostatic environment of the neuronal milieu, by controlling the ... -
The screening of phyto-pesticides for potential adverse effects on human health
(University of the Western Cape, 2010)Pesticides are designed to control or eliminate pests such as insects, rodents, weeds, bacteria, and fungi. They are used at a global scale for agricultural produce. Although pesticides playa significant role in increasing ... -
The impact of nanoparticles on the proteome of cultured human cells
(2021)Living organisms are constantly being exposed to nanoparticles (NPs) in the environment via air, water, soil. Routes of exposure are usually in the form of industrial, occupational exposure, as well as therapeutic ... -
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 ... -
Investigations on the antifungal and cancer modulating properties of extracts from selected species of Tulbaghia
(University of the Western Cape, 2012)Fusarium verticil/ioides (Sacc) Nirenberg a common phytopathogen of maize and maize-based products produces fumonisin B (FB) mycotoxins that have been related to several diseases such as equine leukoencephalomalacia (ELEM), ... -
The characterisation of human coronavirus nl63 proteins
(University of Western Cape, 2021)Human Coronavirus NL63 (HCoV-NL63) is one of seven coronaviruses (CoVs) that cause respiratory disease in the global population. The Membrane (M) and Nucleocapsid (N) proteins are part of the core CoV-structural proteins, ... -
Cell culture biomarkers for monitoring of wastewater pollutants
(University of the Western Cape, 2021)Wastewater is normally composed of a mixture of pollutants. The type and composition of pollutants in a particular wastewater depend on the source of origin. The source and characteristics of a particular wastewater determine ... -
Radiation-induced leukaemia in South Africa: response of lymphocytes and cd34+ cells to different radiation qualities.
(University of the Western Cape, 2020)Epidemiological studies have highlighted that leukaemia can be considered as the most prominent malignancy after radiation exposure during childhood. The lifetime risk on radiation-induced leukaemia for a given dose is 3 ... -
