Identification of sub-clinical biomarkers that predict the risk of developing diabetic cardiomyopathy
(University of the Western Cape, 2022)Cardiovascular disease (CVD) is the leading cause of death of people with obesity and type 2 diabetes (T2DM). According to a statistical report from the World Health Organization (WHO), approximately 17.9 million people ... -
Identification, separation and quantification of persistent organic pollutants using capillary electrophoresis
(University of the Western Cape, 2022)Water quality deterioration and scarcity can be attributed to natural causes and anthropogenic activities which include climate change and an incessant industrialisation, yet with lack of functional and reliable wastewater ... -
Identifying and mapping invasive alien plant individuals and stands from aerial photography and satellite images in the central Hawequa conservation area
(University of the Western Cape, 2012)The Cape Floristic Region, situated at the southern tip of Africa, is one of the world’s most botanically diverse regions. The biodiversity of this region faces various types of threats, which can be divided into three ... -
Identifying potential areas suitable for managed aquifer recharge in Saldanha bay, Western Cape
(University of the Western Cape, 2022)The West Coast in the Western Cape of South Africa is a water-scarce area. Pressure from population and industrial growth, recurring droughts and climate change has resulted in an increasing urgency in the West Coast to ... -
Ideologies and discourses underpinning paradigms of small-scale farmer development: a critical analysis of state and non-governmental extension support programmes in uPhongolo, KwaZulu-Natal
(2013)As a means to reduce poverty particularly in rural areas, the South African government has placed great emphasis on the development of small-scale farmers into becoming commercial farmers. Central to this effort is the ... -
Immobilized catalysts for alkene oxidation
(University of the Western Cape, 2007)Tertiary butyl substituted and unsubstituted Schiff base systems containing N,O donor ligands (Salicylaldimines) with aminotriethoxysilane tail were synthesized and complexed to Copper and Cobalt acetate. The ligands were ... -
The immune-modulating activity of Artemisia afra
(University of the Western Cape, 2010)This study shows that herbs can be effectively screened for potiential bio-activity using in vitro methods. Further studies will be needed to better explore Artemisia afra’s effect on immunoregulation, particularly ... -
The immune-modulating activity of Sutherlandia frutescens
(University of the Western Cape, 2010)The aim of this study was to investigate the effects of Sutherlandia frutescens on the inflammatory response and T cell differentiation in vitro using cytokines as biomarkers. Whole blood cells containing various concentrations ... -
Immunohistochemical analysis of a panel of human and murine markers on xenografted human vaginal mucosa: a comparative study
(University of the Western Cape, 2012)Athymic nude mouse models have been extensively used to study biological behaviour of normal and diseased human tissues. In such models, immune-deficient mice act as hosts for cysts constructed from human material. A unique ... -
Immunosensors developed on clathrate platform compounds
(University of the Western Cape, 2013)Organic noncyclic compounds were used in the development of immunosensor for rapid fish species detection. Flourene derivatives show unique chemical and physical properties because they contain a rigid planar biphenyl unit, ... -
The impact an accredited third party assessor will have on the regulator’s response time
(University of the Western Cape, 2014)Globally regulators have been under scrutiny for delays in market application (MA) approvals. The main issue that surfaces in studies related to these delays is a shortage in competent reviewers. The concept of a third ... -
The impact of different storage temperatures and storage period on the antioxidant activity of pomegranate
(University of Western Cape, 2021)Fruit storage at cold temperatures is normally used to delay decay while maintaining the fruit’s quality. However, storage at low temperatures for a prolonged period causes some important metabolic functions within the ... -
The impact of environment and mergers on the H I content of galaxies in hydrodynamic simulations
(University of the Western Cape, 2015)We quantitatively examine the effects of merger and environment within a cosmological hydrodynamic simulation. We show that our simulation model broadly reproduces the observed scatter in H I at a given stellar mass as ... -
The impact of HIV/AIDS on poverty in the Eastern Cape: a case study of Lusikisiki
(University of the Western Cape, 2007)In recent publications and reports it has been outlined that HIV/AIDS is growing rapidly in the rural communities and the levels of poverty are on the increase. HIV/AIDS has been viewed to have a disastrous impact in almost ... -
The impact of land use and land cover changes on wetland productivity and hydrological systems in the Limpopo transboundary river basin, South Africa
(University of Western Cape, 2021)Wetlands are highly productive systems that act as habitats for a variety of flora and fauna. Despite their ecohydrological significance, wetland ecosystems are under severe threat as a result of environmental changes (e.g. ... -
The impact of nanoparticles on the proteome of cultured human cells
(2021)Living organisms are constantly being exposed to nanoparticles (NPs) in the environment via air, water, soil. Routes of exposure are usually in the form of industrial, occupational exposure, as well as therapeutic ... -
The impact of Niacin on PCSK9 levels in vervet monkeys (Chlorocebus aethiops)
(University of the Western Cape, 2020)Cardiovascular diseases (CVDs) such as ischaemic heart diseases, heart failure and stroke remain a major cause of death globally. Various deep-rooted factors influence CVD development; these include but are not limited ... -
