The effects of nerve stimulation on pacemaking activities of biological tissues.
(1973)The effects on the cardiac cycle length of stimulating the vagus nerves with single supramaximal electrical shocks depended upon when they were stimulated during the cycle. A maximum prolongation of the cardiac cycle was ... -
The effect of dietary egg on human plasma cholesterol and triglyceride levels.
(1990)No abstract available. -
The effect of vitamin B-6 deficiency on the bioavailability of zinc in the rat.
(1990)No abstract available. -
Studies on the isolation of the polymerase genes from the H1N1 influenza A virus.
(1992)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 interrelationship of dietary cholesterol, copper and zinc on plasma lipids and tissue copper and zinc levels in the rat.
(1992)No abstract available. -
The interrelationship of dietary cholesterol, copper and zinc on plasma lipids and tissue copper and zinc levels in the rat.
(1992)No abstract available. -
The Use of an enzyme-linked immunosorbent assay (Elisa) for the determination and characterization of antiendotoxin antibodies.
(1994)Recent clinical studies have highlighted the effectiveness of immunotherapy for Gram-negative bacteraemia in humans. Studies in America, undertaken on patients with Gram-negative bacteraemia, have shown that mortality was ... -
Determination of exposure of humans to selected mycotoxins with particular reference to aflatoxins.
(1995)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.
(1996)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 ... -
Evaluation of the anthropometric parameters and fitness levels of prepubertal Indian soccer players.
(1997)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 ... -
Heart rate response and ECG monitoring in veteran squash players.
(1997)The incidence of sudden death during or after squash play has become a source of concern. In order to screen for coronary artery disease, exercise stress testing has been advocated, by the American College of Sports Medicine ... -
The use of laser doppler fluxmetry in the pre-operative assessment of amputation wound healing in the dysvascular patient.
(1997)Abstract available in PDF. -
The cytotoxic effects of T-2 toxin on normal human lymphocytes.
(1998)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 occurrence and detection of aflatoxin-macromolecular conjugates in humans.
(1998)Aflatoxin Bi (AFBi), a highly toxic fungal metabolite (mycotoxin) of certain strains of Aspergillus, has long been known to be carcinogenic in animal species. Accumulation of epidemiological evidence led to its classification, ... -
The immunocytochemical and electrophoretic localisation of aflatoxin B1-binding proteins in isolated liver mitochondria.
(1998)Mitochondria perform functions which are central to the life of most eukaryotic cells. These organelles can be considered the ultimate energy power house of a living cell. The role of mitochondria in cancer phenotype remains ... -
Mycotoxins in food with particular reference to fumonisin B1 : their health impact on a Kranskop rural community, KwaZulu Natal.
(1998)The use of the multi-mycotoxin screen based on dialysis to analyze foods and feeds for mycotoxins, is well documented. This study investigated the possibility of incorporating FB I into the screen. Maize meal (25g) was ... -
Quantitative determination of fumonisin B1 in biological material.
(1999)The mycotoxin, fumonisin B1 is produced by the mould Fusarium moniliforme, a common contaminant of maize and maize products. Small doses (mg/kg) of ingested fumonisin B1 have been shown to cause diseases and even death in ... -
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 ... -
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 ...
