Proteome signature of breast cancer cells treated with fucoidan
(University of the Western Cape, 2016)Breast cancer is responsible for a large portion of cancer-related deaths. Worldwide, incidence is increasing. Routinely-used treatments for breast cancer are invasive and are associated with a range of side-effects which ... -
A proteomic analysis of drought and salt stress responsive proteins of different sorghum varieties
(University of the Western Cape, 2009)This study reports on a proteomic analysis of sorghum proteomes in response to salt and hyperosmotic stresses. Two-dimensional gel electrophoresis (2DE) in combination with mass spectrometry (MS) was used to separate, ... -
A proteomic analysis of drought and salt stress responsive proteins of different sorghum varieties
(University of the Western Cape, 2009)Sorghum (Sorghum bicolorï, a drought tolerant cereal crop, is not only an important food source in the semi arid/arid regions but also a potential model for studying and gaining a better understanding of the molecular ... -
Proteomic and functional characterisation of biofilm formation in Xylophilus ampelinus
(University of the Western Cape, 2019)Xylophilus ampelinus, the causal agent of bacterial blight of grapevine, inhabits the vascular tissues of infected plants where the cells appear to form assemblages resembling biofilms. Bacterial blight of grapevine ... -
Proteomic and metabolomic characterisation of novel wine yeasts: towards the evaluation and improvements of their ability to produce aromatic sauvignon blanc wines
(University of the Western Cape, 2017)Wine yeast Saccharomyces cerevisiae and wild yeasts e.g. Torulaspora delbrueckii forms an integral part of wine production by converting relatively 'neutral' flavoured Sauvignon blanc grape must into varietal aromatic ... -
Proteomic and SNP analysis of the Cadherin 10 type-II (CDH10) gene, in the South African autistic population
(University of the Western Cape, 2013)Autism or autism spectrum disorder (ASD) is a very diverse neurological disorder that manifests specifically in children and infants between the ages of two to three years of age. An individual suffering is deemed as ... -
Proteomic characterisation of wine yeast strains for the expression of arginases involved in urea formation during fermentation
(University of the Western Cape, 2018)Wine is a fermented beverage widely consumed all over the world as a recreational drink, but is known for its health benefits to humans. However, wine contain urea, a by-product of arginine hydrolysis by arginases expressed ... -
Protocols towards the synthesis of Chiral Isochromanquinones
(University of the Western Cape, 2001)Very few protocols have been developed for the synthesis of chiral isochromanols. In recent years the active group of Giles et al. have developed a very successful and highly efficient protocol using (^9)-ethyl lactate ... -
Proton conducting polymer composite membrane development for Direct Methanol Fuel Cell applications
(University of Western Cape, 2008)The objective of this study was thus to prepare highly proton condictivity membranes that are cheap to manufacture and have low methanol permeability. -
Proton conductivity stability studies by modelling
(University of the Western Cape, 2016)In this thesis, some of the challenges experienced by high temperature polymer electrolyte membrane fuel cells are explored through material modelling techniques. A very important aspect for a fuel cell is that it should ... -
Provenance and depositional environments of early Cretaceous sediments in the Bredasdorp sub-basin, offshore South Africa: An integrated approach
(University of Western Cape, 2020)Southern offshore basins of South Africa are well known as potential provinces of hydrocarbon exploration and production. The complex nature of the Bredasdorp sub-basin’s syn-rift architecture (transform fault system) can ... -
Provenance and depositional environments of early cretaceous sediments in the Bredasdorp Sub-basin, offshore South Africa: an integrated approach
(University of the Western Cape, 2020)Southern offshore basins of South Africa are well known as potential provinces of hydrocarbon exploration and production. The complex nature of the Bredasdorp sub-basin’s syn-rift architecture (transform fault system) can ... -
Proximate determinants of fertility and contraceptive use among currently married women in Ethiopia
(University of the Western Cape, 2017)Fertility is one of the elements in population dynamics that has significant contribution towards changing population size and structure over time. In Ethiopia, fertility dropped only slightly between 2000 and 2005, from ... -
Pseudo proximate analysis: method using wireline logs to estimate components of coal bearing rock matrix without control data
(University of the Western Cape, 2015)Lab conducted proximate analysis of coal bearing rock units calculates the weight percentage of ash, moisture, fixed carbon and volatile matter through a series of combustion steps. The data obtained is quintessential in ... -
Pt Nanophase supported catalysts and electrode systems for water electrolysis
(University of the Western Cape, 2008)In this study novel composite electrodes were developed, in which the catalytic components were deposited in nanoparticulate form. The efficiency of the nanophase catalysts and membrane electrodes were tested in an important ... -
Public participation as governance the role of catchment forums in water governance Mluleki Matiwane
(2012)Catchment forums are concerned groups of people that come together on a voluntary basis in a specific area. They share the same goal and purpose to achieve - sustainable water resources management. These Catchment Forums ... -
Public sector spending in Nigeria: implications for poverty, demographic changes and millennium development goals target
(University of the Western Cape, 2015)Over the last two decades, budgetary allocations to both the Health and Education sectors have been on the increase in Nigeria, while a counter-factual feedback on its effects for various economic groups and distributional ... -
Purification and characterisation of plasmodium falciparum Hypoxanthine phosphoribosyltransferase
(University of the Western Cape, 2007)Malaria remains the most important parasitic disease worldwide. It is estimated that over 500 million infections and more that 2.7 million deaths arising from malaria occur each year. Most (90%) of the infections occur in ... -
Pyramlyl palladium(Il) complexes as phenylacetylene oligomerization and polymerization catalysts'
(University of the Western Cape, 2004)PyrazoM compounds have been extensively used to prepare metal complexes, but it is only recently that they have been investigated as catalysts for the polymerization of unsaturated hydrocarbons. In catalyzn11g the ... -
Pyrazole and pyrazolyl palladium(II) and platinum(II) complexes: synthesis and in vitro evaluation as anticancer agents
(University of the Western Cape, 2004)The use of metallo-pharmaceuticals, such as the platinum drugs, for cancer treatment illustrates the utility of metal complexes as therapeutic agents. Platinum group metal complexes therefore offer potential as anti-tumour ...
