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 ...
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 ...
An investigation into the chemopreventive properties of an indigenous herb, Amaranthus lividus, using cancerous cell lines.
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 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 cytotoxic effects of T-2 toxin on normal human lymphocytes.
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 ...
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. ...
