Cardiopulmonary exercise testing for high-risk South African surgical patients.
(2007)Aim: To determine the prognostic value of cardiopulmonary exercise testing (CPET) for major vascular surgery in South African patients. Methods: CPET has been used in Durban since October 2004 to predict cardiac risk for ... -
A comparative assessment of local, commercial and homemade amahewu with respect to nutritional value, hygiene, and other health benefits to the community.
(2003)Fermentation is a process by which primary food products are modified biochemically by the action of microorganisms and/or their enzymes. Several societies have, over the years, intentionally carried it out to enhance the ... -
Contractile effects of Gunnera perpensa and Rhoicissus tridentata bioactive extracts in isolated rat uterine muscles.
(2014)Abstract available in PDF file. -
The cytotoxic effects of aflatoxin B1 and fumonisin B1 on cultured human cells.
(2004)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. ... -
The cytotoxic effects of deoxynivalenol and fumonisin B1 on the HT-29 human colonic adenocarcinoma cell line.
(2005)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 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 ... -
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 ... -
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 ... -
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 ... -
The effect of dietary egg on human plasma cholesterol and triglyceride levels.
(1990)No abstract available. -
Effect of highly active antiretroviral therapy (HAART) on HIV-1 tat protein-induced neurotoxicity.
(2014)Background: HIV-1-trans-activating (Tat) protein has been associated with development of HIVassociated neurocognitive disorder (HAND). Previous studies have demonstrated that Tat protein causes neurotoxicity through an ... -
The effect of ultradistance running on premenopausal women of different ethnic groups.
(2005)No abstract available. -
The effect of vitamin B-6 deficiency on copper, zinc and iron balance in the rat.
(1988)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 effect of vitamin B-6 deficiency on the bioavailability of zinc in the rat.
(1990)No abstract available. -
The effect of vitamin B-6 deficiency on the levels of tissue copper, iron and zinc in the rat.
(1989)No abstract available. -
Effects of antipsychotic dose reduction on metabolic syndrome in patients with first episode psychosis treated with a long-acting injectable antipsychotic.
(2019)Background: The introduction of antipsychotics has been a significant milestone in the treatment of schizophrenia. However, these agents have several important side effects, such as metabolic syndrome. Options to curb these ... -
Effects of Momordica balsamina methanolic extract on cardiovascular and haematological function in streptozotocin-induced diabetic rats : effects on selected markers.
(2018)Background The hyperglycaemia-induced haemanetic changes reduces the oxygen-carrying capacity of erythrocytes, thus aggravating cardiovascular disorders in diabetic patients. The conventional therapies have been shown to ... -
Effects of momordica balsamina on glucose handling in high fat high carbohydrate induced prediabetic rat model and glucose handling in C2C12 induced insulin resistant cell lines: effects on selected metabolic markers.
(2020)Increased consumption of fat and high carbohydrate coincided with increased prevalence in type 2 diabetes, a condition whose onset is always preceded by prediabetes. Prediabetes is best characterised by hyperglycaemia, ... -
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 ... -
