Determination of exposure of humans to selected mycotoxins with particular reference to aflatoxins.
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 ...
A cytotoxic evaluation of aflatoxin B1, zearalenone and their epoxide derivatives using human cell lines.
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 ...
The effect of vitamin B-6 deficiency on copper, zinc and iron balance in the rat.
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 value of morphological analysis in duodenal ulcer therapy
This study was designed to examine two premises: that the morphological "severity" of duodenal ulcers (DU) may influence the incidence of drug mediated healing and the morphological "quality" of healing after curative ...
Evaluation of the anthropometric parameters and fitness levels of prepubertal Indian soccer players.
Due to the lack of morphological data on prepubertal Indian male soccer players in South Africa, this study was undertaken on ninety male prepubertal subjects. The subjects were divided into three groups of thirty subjects ...
The effect of ultradistance running on premenopausal women of different ethnic groups.
No abstract available.
Studies on the isolation of the polymerase genes from the H1N1 influenza A virus.
Vaccines directed against the influenza virus become ineffective due to continuous mutation. An alternative approach might be to control replication at the genomic level by enzymatic methylation of the polymerase genes. ...
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. ...
