Immunological techniques for the serum determination of specific-IgE levels among workers exposed to seafood allergens
(Cape Technikon, 2003)Allergic conditions among workers processing seafood are most often related to inhalation of the seafood antigens or via direct unprotected handling of the seafood and its products. This can cause sensitised individuals ... -
In vitro anti-bacterial activity of titanium oxide nano-composites containing benzalkonium chloride and chlorhexidine gluconate
(Cape Peninsula University of Technology, 2013)Newly developed and commercial dental resins which are commonly used nowadays have to be tested for their antimicrobial susceptibility. The purpose of this in vitro study was to investigate the antimicrobial activity of ... -

An in vitro comparison of cellular destruction and metabolic effects occurring in stored, leuco-reduced and irradiated red blood cells
(Cape Peninsula University of Technology, 2016)Biochemical and haematological changes occur in red blood cellular products during the recommended storage period of 35 to 42 days at 1°C to 6°C. The restriction of the sodium/potassium pump at specified temperatures result ... -
In vitro prediction of inherent cellular radiosensitivity
(Cape Peninsula University of Technology, 2005)The principal objective in irradiating tumours is to permanently inhibit their reproductive ability. More than half of all malignancies are primarily treated with radiation but tumours of different histologies differ ... -
Influence of temperature and pH on corrosion resistance of Ni–Cr and Co–Cr dental alloys on oral environment
(Cape Peninsula University of Technology, 2015)Dental alloys are widely used in direct contact with oral tissue. In recent years after the price of gold significantly increased, cheaper dental materials were generally considered in the market particularly dental ... -
Investigating the association between Leucocyte Telomere length and glucose intolerance
(Cape Peninsula University of Technology, 2017)Background: Telomeres are DNA-proteins situated at the ends of linear chromosomes, responsible for genome stabilization. A link has been previously described between leucocyte telomere length (LTL) and age-related inflammatory ... -
The leukocyte apoptosis assay : a clinical predictor of radiosensitivity?
(Cape Peninsula University of Technology, 2009)The main objective of radiotherapy is to completely eradicate tumours while preserving the integrity of the normal surrounding tissue. The severity of normal tissue reactions varies considerably amongst individuals. ... -
The level and persistence of antibiotic resistant strains of bacteria in wastewater before, during and after treatment at a municipal wastewater treatment plant in Stellenbosch
(Cape Peninsula University of Technology, 2015)Wastewater treatment plants (WWTPs) are designed to remove/decrease conventional pollution parameters from the wastewater influent, so that the final effluent (run off) does not compromise the receiving surface water source. ... -
Marker studies of the solid state formation of CrSi2 on Pd2Si
(Peninsula Technikon, 1998)The chemical system, Si < >1 Pd 1Cr, was investigated to study the formation of CrSil on polycrystalline PdlSi, formed on Si<IOO> and epitaxial PdlSi formed on Si<lll>. To ascertain the reaction mechanism during the ... -
Markers of chronic immune activation and T-cell function in hyperglycaemia
(Cape Peninsula University of Technology, 2017)Type 2 diabetes mellitus (T2DM) is a chronic inflammatory condition characterised by hyperglycaemia; continuous activation of T-lymphocytes and immune dysregulation. Although the exact mechanisms of these phenomena are not ... -
Mitochondrial DNA heteroplasmy in radiation induced myelodysplasia and leukaemia
(Cape Technikon, 1996)Haematological defects observed in clonal deletions of mtDNA and the inhibition of mitochondrial function by benzene and chloramphenicol, suggest a role for mtDNA in the pathogenesis of radiation - induced preleukaemia ... -
Mitochondrial DNA heteroplasmy in radiation induced myelodysplasia and leukaemia
(Cape Technikon, 1996)Haematol.ogical defects observed in cl.onal deletions of mtDNA and the inhibition of mitochondrial function by benzene and chloramphenicol., suggest a role for mtDNA in the pathogenesis of radiation - induced ... -
Modulation of oxidative stress biomarkers by rooibos in adults at risk of developing coronary heart disease
(Cape Peninsula University of Technology, 2008)Observational studies link higher intake of polyphenols from plant based foods and beverages with a lower risk of cardiovascular disease (CVD) which remains the leading cause of death in the world. Although the mechanisms ... -
Modulation of oxidative stress by rooibos (aspalathus linearis) herbal tea, chinese green (camellia sinensis) tea and commercial tea supplements using a rodent model
(Cape Peninsula University of Technology, 2012)Human and experimental animal studies have shown that biomarkers of oxidative damage are elevated in subjects with certain diseases or risk factors. Consequently, it is hypothesized that oxidative stress plays an important ... -
Modulation of postprandial oxidative stress by rooibos (aspalathus linearis) in normolipidaemic individuals
(Cape Peninsula University of Technology, 2010)Consumption of sucrose with a meal containing oxidised and oxidisable lipids cause an increase in oxidative stress which is referred to as postprandial oxidative stress. The modulating effect on postprandial oxidative ... -
Modulation of ultrviolet light induced skin carcinogenesis by extracts of Rooibos and Honeybush using a mouse model:elucidating possible protective mechanisms
(Cape Peninsula University of Technology, 2009)This thesis provides the first scientific evidence of the photoprotective properties of rooibos and honeybush herbal tea extracts and to some extent, two major honeybush polyphenols, hesperidin and mangiferin. These ... -
Molecular characterisation of Mycobacterium Tuberculosis, clinical isolates obtained in the Khomas region, Windhoek, Namibia
(Cape Peninsula University of Technology, 2017)According to the Namibia National Tuberculosis Control Programme (NTCP) report of 2008, Namibia has one of the highest TB infection rates in the world with a case notification rate of 748/100,000. Rapid, specific and ... -
Molecular characterisation of the multi-antibiotic resistant bacteria, Klebsiella Pneumoniae isolated from nosocomial infections
(Cape Peninsula University of Technology, 2017)Background: It is well established that Klebsiella pneumoniae (K. pneumoniae) is an opportunistic pathogenic organism that has been frequently identified as the cause of nosocomial and community acquired infections. ... -
Mutation screening of the ENPP1 gene and its possible contribution to the development of obesity/overweight and metabolic syndrome in South African children
(Cape Peninsula University of Technology, 2008)Epidemiological reports have shown that South Africa, whilst a developing country, irs overweight and obesity prevalence rates in children is fast approaching those seen in the developed world. This country's population ...
