Cardiopulmonary exercise testing for high-risk South African surgical patients.
(2007)Aim: To determine the prognostic value of cardiopulmonary exercise testing (CPET) for major vascular surgery in South African patients. Methods: CPET has been used in Durban since October 2004 to predict cardiac risk for ... -
The case for critical thought : an investigation into contemporary determinist knowledge, its social effects, and the alternative offered by a 'mode 2' approach to teaching, learning and research.
(2002)This thesis is centrally concerned with the current nee-liberal world order and its effects upon society. It is concerned to expose the contradictions and weaknesses within the knowledge systems that underpin our political ... -
Chemical investigation of isihlambezo or traditional pregnancy-related medicines.
(2004)This study was undertaken to redress the scant knowledge regarding the chemistry and mode of action of pregnancy-related traditional medicines, or isihlambezo (Zulu), which are used by 60 to 80% of women in South Africa. ... -
A comparative assessment of local, commercial and homemade amahewu with respect to nutritional value, hygiene, and other health benefits to the community.
(2003)Fermentation is a process by which primary food products are modified biochemically by the action of microorganisms and/or their enzymes. Several societies have, over the years, intentionally carried it out to enhance the ... -
Contractile effects of Gunnera perpensa and Rhoicissus tridentata bioactive extracts in isolated rat uterine muscles.
(2014)Abstract available in PDF file. -
The cytotoxic effects of aflatoxin B1 and fumonisin B1 on cultured human cells.
(2004)Aflatoxin B1 (AFB1) and Fumonisin B1 (FB1), potentially cytotoxic and carcinogenic mycotoxins are common contaminants of agricultural commodities in South Africa and thus could be detrimental to the human immune system. ... -
The cytotoxic effects of deoxynivalenol and fumonisin B1 on the HT-29 human colonic adenocarcinoma cell line.
(2005)The human population can be considered as a subject of combined exposure to chemicals against which the gastrointestinal tract represents the first barrier. The most relevant are those compounds that occur in plants which ... -
The cytotoxic effects of T-2 toxin on normal human lymphocytes.
(1998)T -2 toxin is an immunosuppressive mycotoxin that has been conjoined with several symptoms and diseases as early as the turn of the century, but whose mechanisms of action are still being investigated. Accordingly, this ... -
A cytotoxic evaluation of aflatoxin B1, zearalenone and their epoxide derivatives using human cell lines.
(1996)Since the discovery of mycotoxins in food, the thrust of biochemical and toxicological research has been carried out on animals which has proven to be uncoordinated and not easily extrapolated to humans. Over the last ... -
Determination of exposure of humans to selected mycotoxins with particular reference to aflatoxins.
(1995)Mycotoxins are poisonous secondary metabolites commonly produced by fungi and are involved in human disease conditions known as mycotoxicoses. There is evidence to show that food eaten by the rural Black population of ... -
Development and application of an ELISA method of analysis for fumonisins
(2000)Fumonisins, mycotoxins produced by the fungus, Fusarium moniliforme, which grows on maize, are a major worldwide agricultural problem. Consumption of contaminated maize feeds causes a wide variety of toxic effects in animals ... -
The effect of dietary egg on human plasma cholesterol and triglyceride levels.
(1990)No abstract available. -
Effect of highly active antiretroviral therapy (HAART) on HIV-1 tat protein-induced neurotoxicity.
(2014)Background: HIV-1-trans-activating (Tat) protein has been associated with development of HIVassociated neurocognitive disorder (HAND). Previous studies have demonstrated that Tat protein causes neurotoxicity through an ... -
The effect of sildenafil citrate and kraussianone-2 on pre-eclampsia-like manifestations in Sprague-Dawley rats.
(2011)Pre-eclampsia, often described as toxaemia of pregnancy, historically represents one of the most widely investigated conditions relating to human reproduction. To date no firm cure has been found and a clear, well defined ... -
The effect of ultradistance running on premenopausal women of different ethnic groups.
(2005)No abstract available. -
The effect of vitamin B-6 deficiency on copper, zinc and iron balance in the rat.
(1988)In order to address the contradictory reports on the rat trace element status during a vitamin 8-6 deficiency, Zn, Cu and Fe balance was assessed over 8 weeks in 3 groups of young male rats. Group 1 was the control group ... -
The effect of vitamin B-6 deficiency on the bioavailability of zinc in the rat.
(1990)No abstract available. -
The effect of vitamin B-6 deficiency on the levels of tissue copper, iron and zinc in the rat.
(1989)No abstract available. -
The effects of insulin and Syzygium aromaticum-derived oleanolic acid containing dermal patches on kidney function and renal expression of glucose transporters in streptozotocin-induced diabetic rats.
(2014)Introduction The tight glycaemic control required to attenuate chronic complications in type 1 diabetes mellitus requires multiple daily injections of bolus insulin which have been reported to be associated with Na+ ... -
Effects of maslimic acid and related triterpene derivatives on kidney function of male Sprague-Dawley rats.
(2014)Reports indicate that hyperglycaemia leads to development of kidney complications which result in sodium retention, decrease in glomerular filtration rate (GFR) and high blood pressure. Various biochemical processes such ...
