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 determination of unilateral ratios (knee and shoulder muscle strength), of provincial cricketers.
(2002)Abstract available in PDF. -
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 ... -
An investigation into the apoptotic inducing effect of fusaric acid on human lymphocytes and its role in cell growth inhibition.
(2003)Fusaric acid (FA) (5-butylpicolinic acid) is a divalent ion chelating agent that has low affinity for Ca2+ and Mg2+ and a high affinity for other essential metal ions such as Fe2+ Mn2+, Zn2+ and Cu2+. Its mode of action ... -
The fate of mycotoxins in non-alcoholic lactic acid maize meal fermentation.
(2003)This study was aimed at investigating the potential of lactic acid fermentation in reducing myco toxin concentration in maize meal products. Maize meal was spiked separately with aflatoxin Bi, fumonism Bi, and zearalenone, ... -
An immunohistochemical evaluation of the effect of salt (NaCI) on adrenal adrenomedullin content in Dahl rats.
(2003)Adrenomedullin (ADM) is a 52 amino acid vasodilator peptide isolated, in 1993, from human pheochromocytoma. It has been demonstrated in the adrenal medulla of several mammalian species, including humans and rats. There ... -
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 effect of ultradistance running on premenopausal women of different ethnic groups.
(2005)No abstract available. -
The kind of society required for human flourishing : a critical comparison of the formation of ethical character in Aristotelian and African ethics.
(2005)One thing that ethics attempts to determine is the right way to live in order to attain human flourishing. Both Aristotelian and African ethics give us communitarian accounts of how flourishing is attained by individuals ... -
An investigation into the chemopreventive properties of an indigenous herb, Amaranthus lividus, using cancerous cell lines.
(2005)Chemoprevention may be defined as the inhibition, delay or reversal of carcinogenesis by dietary compounds or their derivatives. "Imifino" is a collective name for many wild plants used predominantly by rural people as ... -
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 ... -
Oxidative stress of tissue in hypertensive rats.
(2006)Oxidative stress, resulting from an antioxidant/free radical imbalance, is considered to be an important etiologic factor in the patho-physiological changes associated with salt sensitive hypertension. An important unresolved ... -
Optimisation of an analytical method for the analysis of folic acid derivatives in biological materials.
(2007)Folic acid is a water-soluble, B-complex vitamin influencing a number of biological processes in humans and particularly important in the prevention of neural tube defects (associated with spinal bifida) in unborn children. ... -
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 ... -
Effects of plants-derived oleanolic acid in an in-vitro model hyperglycaemia-induced oxidative stress.
(2010)Diabetes mellitus (DM) has become a global threat in developing and developed countries, where diabetic patients are more prone to cardiovascular complications, a condition called diabetic cardiomyopathy. Studies have shown ... -
The effects of plant-derived oleanolic acid on kidney function in male Sprague-Dawley rats and, in cell lines of the kidney and liver.
(2012)Adverse effects and increasing cost of therapeutic drugs have renewed an interest in the use of medicinal plant products for the treatment of a variety of chronic disorders. One such bioactive plant-derived compound is ... -
