Bacterial community composition of an urban river in the North West Province, South Africa, in relation to physico-chemical water quality
(Springer, 2016)The aim of this study was to determine the impacts of anthropogenic disturbances on bacterial community composition in an urban river (Mooi River). Physico-chemical analysis, bacterial enumeration and 454-pyrosequencing ... -
Bioaccumulation and human health risk assessment of DDT and other organochlorine pesticides in an apex aquatic predator from a premier conservation area
(Elsevier, 2016)With the second highest gross domestic product in Africa, South Africa is known to have a high pesticide usage, including the highly persistent and banned group of organochlorine pesticides (OCPs). South Africa is also one ... -
Biomarkers in tigerfish (Hydrocynus vittatus) as indicators of metal and organic pollution in ecologically sensitive subtropical rivers
(Elsevier, 2018)Studies have shown high levels of contamination of both metals and organochlorine pesticides (OCPs) in aquatic systems of the world renowned Kruger National Park, South Africa. With effects evident in top predators, ... -
Exploratory data analysis of the dependencies between skin permeability, molecular weight and log P
(Govi-Verlag, 2016)Molecular weight and log P remain the most frequently used physicochemical properties in models that predict skin permeability. However, several reports over the past two decades have suggested that predictions made by ... -
Metabolomics of bilharziasis
(North-West University, 2012)Bilharziasis, a disease that is a major health problem in tropical and subtropical countries, is caused by worms of the genus Schistosoma. The main disease–causing species are S. haematobium, S. mansoni and S. japonicum. ... -
A metabolomics study of selected perturbations of normal human metabolism
(North-West University, 2010)Metabolism is an integrated network of biochemical pathways involving a series of enzymecatalysed anabolic or catabolic reactions in cells. Metabolites are chemical compounds that are involved in or are products ... -
Molecular profiling of microbial population dynamics in environmental water
(North-West University, 2015)Increasing socio-economic growth and development of South Africa’s freshwater systems require continuous augmentation of water sources to meet the growing water requirements of communities and industries. Anthropogenic ... -
