The cytotoxic effects of deoxynivalenol and fumonisin B1 on the HT-29 human colonic adenocarcinoma cell line.
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 aflatoxin B1 and fumonisin B1 on cultured human cells.
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. ...
Development and application of an ELISA method of analysis for fumonisins
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 ...
An investigation into the apoptotic inducing effect of fusaric acid on human lymphocytes and its role in cell growth inhibition.
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 kind of society required for human flourishing : a critical comparison of the formation of ethical character in Aristotelian and African ethics.
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 ...
Optimisation of an analytical method for the analysis of folic acid derivatives in biological materials.

Cardiopulmonary exercise testing for high-risk South African surgical patients.
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 fate of mycotoxins in non-alcoholic lactic acid maize meal fermentation.
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, ...
