Semen characteristics of free-ranging African elephants (Loxodonta africana) and Southern white rhinoceros (Ceratotherium simum simum) using Computer-aided sperm analysis, Electron microscopy and Genomics as diagnostic tools
(University of the Western Cape, 2016)The survival of free-ranging (in situ) African elephant and Southern white rhinoceros populations are currently being challenged on a daily basis in Africa. Reproductive health is considered a vital component of species ... -
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 ... -
Sperm mitochondria: species specificity and relationships to sperm morphometric features and sperm function in selected mammalian species
(University of the Western Cape, 2011)Numerous studies on mammalian spermatozoa have reported large variations in the dimensions of the main sperm structural components, namely the head, midpiece and flagellum. These variations in sperm architecture are believed ... -
Structural and functional characterization of human DDX5 and its interaction with NS5B of hepatitis C virus
(University of the Western Cape, 2011)Hepatitis C was first recognized as a transfusion-associated liver disease not caused by hepatitis A or hepatitis B virus after serological tests were developed to screen for their presence in the blood. The infectious ... -
Synergistic effects of mixtures of fungicides and medicinal plant extracts against Botrytis cinerea
(University of the Western Cape, 2008)We hypothesize that South African medicinal plants contain compounds that can act in synergism with synthetic antifungal compounds. Four fungicides - Sporekill™, Rovral™, Terminator™ and Teldor™ at doses 0.1, 0.2, 0.4 and ... -

The antifungal effect of Salvadora persica and Euclea natalensis on Candida isolates from Libyan patients with type 2 Diabetes mellitus.
(University of the Western Cape, 2018)Improved oral hygiene plays a vital role on quality of health and well-being of diabetic patients. Poor oral health leads to an increased incidence of oral diseases, particularly oral candidiasis. The emergence and global ... -
The assessment of Namibian water resources for endocrine disruptors
(University of the Western Cape, 2018)Namibia is the driest sub-Saharan country in Africa and it is characterised by low and variable rainfall. As a result, potable water in this mostly semi-arid country is considered an extremely valuable resource. Given ... -
The in vitro effects of heavy metals and nanoparticles on the immune system
(University of the Western Cape, 2017)Heavy metals and nanoparticles may be released into the environment due to their use and applications. Sources of high, toxic metal concentrations may result from leachates from hazardous waste sites, discharge from ... -
Typha capensis—An electron rich resource for the synthesis of phytochemical-encapsulated gold nanoparticles through green nanotechnology
(University of the Western Cape, 2020)Typha capensis (T. capensis), commonly known as bulrush, is a medicinal plant found growing in the wetland areas of South Africa. In traditional medicine, rhizome decoctions of T. capensis are used to treat a wide variety ... -
Ursolic acid and oleanolic acid as novel therapeutic agents in breast cancer
(University of the Western Cape, 2015)Breast cancer is one of the most common cancers among women in South Africa and the second leading cause of cancer death after lung cancer. According to the American Cancer Society 2015, women have a 12% chance of developing ...
