Genome-wide annotation of chemosensory and glutamate-gated receptors, and related genes in Glossina morsitans morsitans tsetse fly
(University of the Western Cape, 2014)Tsetse flies are the sole vectors of trypanosomes that cause nagana and sleeping sickness in animals and humans respectively in tropical Africa. Tsetse are unique: both sexes adults are exclusive blood-feeders, females are ... -
Genome-wide identification and comprehensive analysis of transcriptionsl desert regions
(University of the Western Cape, 2009)The initiation of transcription in mammalian genomes predominatly occurs at 5' promoter regions, however increasingly initiation events have been observed within introns, coding exons and 3' UTRs. Nevertheless there ... -
Genomic and proteomic analysis of drought tolerance in Sorghum (Sorghum bicolor (L.) Moench)
(University of the Western Cape, 2014)Drought is the most complex phenomenon that remained to be a potential and historic challenge to human welfare. It affects plant productivity by eliciting perturbations related to a pathway that controls a normal, ... -
Genomic diversity and functional analysis of the solute carrier genes within indigenous African and Cape Admixed populations
(University of the Western Cape, 2016)Solute carrier transporters belonging to the major facilitator family of membrane transporter are increasingly being recognized as a possible mechanism to explain inter-individual variation in drug efficacy and response. ... -
Genomic epidemiology of Rift Valley fever in East Africa
(University of the Western Cape, 2023)Rift Valley fever (RVF) is a climate-driven zoonotic disease of significant importance to public and livestock health given its epidemic potential. The disease was first identified in 1930 in the great rift valley region ... -
Genomic instability in South African breast cancer patients
(2013)Breast cancer (BC) is one of the most common malignancies in women. Death results from treatment failure and metastatic disease. Thousands of lives might be saved if it was possible to detect and eliminate occult metastatic ... -
The genus Spongites (Corallinales, Rhodophyta) in South Africa
(University of the Western Cape, 2019)Coralline red algae (Corallinales, Hapalidiales, Sporolithales: Corallinophycidae, Rhodophyta) are widespread and common in all the world’s oceans (Adey & McIntyre 1973; Johansen 1981; Littler et al. 1985; Björk et al. ... -
Geo-physical parameter forecasting on imagery{based data sets using machine learning techniques
(University of Western Cape, 2021)This research objectively investigates the e ectiveness of machine learning (ML) tools towards predicting several geo-physical parameters. This is based on a large number of studies that have reported high levels of ... -
Geochemical and mineralogical evaluation of toxic contaminants mobility in weathered coal fly ash: as a case study, Tutuka dump site, South Africa
(University of the Western Cape, 2011)The management and disposal of huge volumes of coal combustion by products such as fly ash has constituted a major challenge to the environment. In most cases due to the inadequate alternative use of coal fly ash, the ... -
