The fate of mycotoxins in non-alcoholic lactic acid maize meal fermentation.
(2003)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, ... -
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 ... -
HIV-1 transactivator of transcription (TAT) protein causes neurotoxicity via astrocyte activation.
(2015)HIV is most well-known for its negative effects on the immune system and the resulting development of AIDS, however it also has severe damaging effects on the central nervous system. Many infected individuals exhibit ... -
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 ... -
An immunohistochemical evaluation of the effect of salt (NaCI) on adrenal adrenomedullin content in Dahl rats.
(2003)Adrenomedullin (ADM) is a 52 amino acid vasodilator peptide isolated, in 1993, from human pheochromocytoma. It has been demonstrated in the adrenal medulla of several mammalian species, including humans and rats. There ... -
The interrelationship of dietary cholesterol, copper and zinc on plasma lipids and tissue copper and zinc levels in the rat.

The interrelationship of dietary cholesterol, copper and zinc on plasma lipids and tissue copper and zinc levels in the rat.
(1992)No abstract available. -
Investigating changes to the insulin signalling pathway in a diet-induced pre-diabetic rat model: effects on selected markers.
(2019)No abstract available. -
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 ... -
An investigation into the chemopreventive properties of an indigenous herb, Amaranthus lividus, using cancerous cell lines.
(2005)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 kind of society required for human flourishing : a critical comparison of the formation of ethical character in Aristotelian and African ethics.
(2005)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 ... -
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 ... -
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 optimisation of a preeclampsia-like L-NAME rat model : a focus on utero-placental dysfunction.
(2014)Preeclampsia is a multi-system pregnancy syndrome characterized by the sudden onset of hypertension, escalated proteinuria and in some cases oedema usually after 20 weeks of gestation. Preeclampsia is further categorized ... -
Optimisation of an analytical method for the analysis of folic acid derivatives in biological materials.
(2007)Folic acid is a water-soluble, B-complex vitamin influencing a number of biological processes in humans and particularly important in the prevention of neural tube defects (associated with spinal bifida) in unborn children. ... -
Oxidative stress of tissue in hypertensive rats.
(2006)Oxidative stress, resulting from an antioxidant/free radical imbalance, is considered to be an important etiologic factor in the patho-physiological changes associated with salt sensitive hypertension. An important unresolved ... -
Prenatal stress and febrile seizures effects on the epigenetic mechanisms involved in cognitive function following treatment with Searsia chirindensis.
(2016)Febrile seizures are of growing concern in the health fraternity within the African continent. These seizures predominantly affect children between the ages of 3 months and 5 years of age. Stress during pregnancy may ... -
A quantification of heat load as assessed by indicators of tissue damage in rats.
(1984)Heatstroke is an illness that occurs when body temperature is grossly elevated, causing widespread tissue damage. The extent of tissue damage depends on the level of body temperature elevation and the duration. Despite ... -
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 ... -
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. ...
