The effects of Exomis micriphylla and Atriplex lindleyi on metabolism and health
(University of the Western Cape, 2002)For many decades people have used plants for healing various ailments. Plant products have been used in herbal remedies especially for their anti-infective properties. The following study was undertaken to assess the ... -
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 ... -
Effects of green, black and rooibos tea, coffee and buchu on testosterone production by mouse testicular cultures
(University of the Western Cape, 2013)Modulation of the male reproductive system occurs as a result of exposure to endocrine disrupting compounds (EDCs) in different life stages. The effects of EDCs on the male reproductive system include infertility, decreased ... -
The effects of hypoxis hemerocallidea on blood glucose levels in rats with Type 2 diabetes
(University of the Western Cape, 2015)About 180 million people have been estimated to suffer from type 2 diabetes (T2DM) in 2006 and the annual death rate due to this disease was 3 million by that time. More than 400 medicinal plants used for the treatment ... -
The effects of maternal nicotine exposure during pregnancy or lactation on hypertension of the offspring
(University of the Western Cape, 2016)Blood pressure and heart rate is known to increase during smoking. These effects are specifically associated with nicotine while the other components of tobacco smoke seem to be of minor importance. It is becoming increasingly ... -
The effects of nanomaterials, in the presence and absence of serum proteins, on testicular cell metabolic processes and steroidogenesis
(University of the Western Cape, 2014)The aim of this study is to be the first to ascertain the effects of silver nanoparticles on testosterone production. The Ag NPs used for this study have the following characteristics; purity ≥ 99.5%; 66.7 % of particles ... -
The effects of PGA2 on cell cycle progression in oesophageal carcinoma cells
(University of the Western Cape, 2003)The molecular mechanisms causing anti-mitotic and cytotoxic effects of prostaglandin .A2 [PGA2 (CzoHroOa)] treatment of human oesophageal carcinoma (WHCO3) cells were investigated. WHCO3 cells, incubated with cytotoxic ... -
The effects of silver nanoparticles on the expression of protein biomarkers of cell stress, apoptosis and inflammation by the human liver cancer cell line, HepG2
(University of Western Cape, 2021)Nanoscience is the study of phenomena and objects at the nanoscale (around 1-100 nm), socalled nanomaterials. These nanomaterials exhibit novel properties that are often very different to those of the bulk materials used ... -
The effects of titanium oxide nanoparticles on cultured cells and the immune system
(University of Western Cape, 2021)Engineered nanomaterials derived from various bulk materials are being developed in ever larger quantities and with very diverse chemical compositions. The physical and chemical properties of the smaller nanoparticles are ... -
The effects of various combinations of different classes of anticancer drugs and tyrosine kinase inhibitors on the human MCF-7 breast carcinoma cell line
(University of the Western Cape, 2014)This study investigated the effects of TKIs on the growth and proliferation of MCF-7 breast carcinoma cells in culture. MCF-7 cells were exposed to different concentrations of TKIs alone and in combination with each other. ... -
The efficiency of drinking water treatment plants in removing immunotoxins
(University of the Western Cape, 2010)The aim of this study was to evaluate the effectiveness of water treatment processes of two drinking water plants to remove immunotoxins and steroid hormones. Raw and treated drinking water was screened for effects on ... -
An electrophysiological exploration into the Sertoli cell, utilizing plant extracts with a view to contraception
(University of the western cape, 2003)Certa in medicinal plant extracts have been shown to have a contraceptive effect on male rats (Rajasekaran et al. , 1988) and mice (Kong et al., 1986). A possible site for the mechanism of action has been identified as the ... -
Epidemiological study of Tuberculosis in Macassar camp
(University of the Western Cape, 1995)The aim of this study was to determine and evaluate the prevalence of TB infection, active TB cases and the risk factors associated with TB infection in Macassar Camp in Macassar (about 40 km from Cape Town on the False ... -
Evaluating cape honey bee sperm quality and the in vitro effect of miticides on sperm functionality and structure
(University of Western Cape, 2021)Apis mellifera (honey bees) are essential pollinators and thus considered a keystone species. Reproductive success is therefore important to the survival of the species, with drone sperm quality playing a vital role in ... -
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 ... -
Evaluation of standard and development of new sperm function tests in selected primate species
(University of the Western Cape, 2017)Male infertility in humans has increased in the last few decades and could be as high as 40%, while up to 50% of these men have ''unexplained'' (idiopathic) infertility. Although newly developed molecular techniques have ... -
Evaluation of sperm functionality in non-human primates, focussing on sperm capacitation
(University of the Western Cape, 2019)The incidence of male infertility is increasing, with up to 50% of infertile males having “unexplained” (idiopathic) infertility. Newly developed molecular techniques have great value in detecting subtle causes of male ... -
An evaluation of the biopesticidal characteristics of Helichrysum marifolium and Helichrysum patulum and their effects on animal metabolism
