Novel siRNA lipoplexes : their targeted and untargeted delivery to mammalian cells in culture.
The high gene knockdown specificity and efficiency of RNA interference (RNAi) provides a potentially viable avenue for the development of a new class of nucleic acid therapeutics for gene-based disease conditions. However, ...
Molecular characterization of selected enterococcus strains (previously streptococcus) using genotyping techniques.
The genus Enterococcus comprises of a group of commensal organisms of the human gut which has been associated with cases of endocarditis and urinary tract infections. In the present study, 12 Enterococcus isolates were ...
Induction of polyploidy in Eucalyptus species and interspecific hybrids.
A large sector of the forestry industry of South Africa comprises Eucalyptus species, covering approximately 49% of the forestry plantation area. Polyploidy induction has become an attractive tool to increase yield and ...
Regulation of the thioredoxin system in Saccharomyces cerevisiae.
The thioredoxin system consisting of thioredoxin (Trx), thioredoxin reductase and NADPH plays a significant role in a large number of redox-dependent processes such as DNA synthesis and anti-oxidant defense. Elevated levels ...
Genetic identification of kikuyu grass (Pennisetum clandestinum) cultivars by RAPD and ISSR techniques.
Kikuyu grass (Pennisetum clandestinum), originally from tropical and subtropical African countries, is one of the most important pasture grasses in the higher rainfall regions of South Africa (of utmost importance in ...
Cloning, expression and purification of the subunits of the Mannose PTS Permease of Listeria monocytogenes EGD.
The disease listeriosis is caused by Listeria monocytogenes. This common food-borne disease has been responsible for about 0.1 to 10 cases per million inhabitants per year. However, this disease is serious with its high ...
The transformation of South African soya bean cultivars with a synthetic Basta resistance gene.
The development of a genetic engineering system for soya bean (Glycine max L.) is described in this thesis. Routine tissue culture regeneration systems were developed for South African cultivars of soya bean despite the ...
Genetic evaluation of South African indigenous chickens for disease resistance.
An alternative standard disease control method would be selective breeding in order to increase disease resistance. To set up marker assisted selection programmes, knowledge of the genetic diversity of the chickens is ...
Molecular detection and genetic characterization of antimicrobial resistance genes in foodborne pathogens isolated from slaughtered broiler chickens in Durban.
Salmonella and Staphylococcus aureus are the most troublesome micro-organisms in poultry industry, because their presence poses health hazards and risks to consumers and to the economy of the country. Since they entail ...
