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 ...
The possible implication of selected Fusarium Mycotoxins in the aetiology of brain cancer.
The central nervous system is a potential site of action for the Fusarium mycotoxin Fumonisin B1 (FB1), and is exemplified in horses by the disease equine leukoencephalomalacia. Structurally resembling sphingoid bases, FB1 ...
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 ...
