(University of Pretoria, 2006-06-23)The saliva of hematophagous ectoparasites contains a cocktail of vasodilators, anticoagulants and immunosuppressors that maintain blood in a liquid state at the site of the lesion and evade the host's defense mechanisms ...
-
(University of Pretoria, 2017)The main focus of this research was to study in detail the selected plant growth promoting bacteria (PGPR) from Bacillus group. PGPR have been described as possible solution to the negative effects of chemicals fertilizers ...
-
(University of Pretoria, 2015)In 1963 the study of marine natural products was just beginning and there were only a handful of public records with only one of these publications reporting a new compound. There has since been 9220 papers published, ...
-
(University of Pretoria, 2009-11-03)Tea is made from the young leaves of Camellia sinensis, an evergreen, outbreeding tree species. The replacing of seedling with clonal plantations and the use of small numbers of parental plants in breeding programs could ...
-
(University of Pretoria, 2010-11-05)Background : Host protein beta-2 microglobulin (β2m) is incorporated into the human immunodeficiency virus (HIV) -1 coat during budding. Antibodies directed to R7V, an epitope contained in β2m, increased with the duration ...

(University of Pretoria, 2014)No abstract
-
(University of Pretoria, 2013)The cattle tick, Rhipicephalus microplus, has a debilitating effect on the livestock industry worldwide, owing to its being a vector of the causative agents of bovine babesiosis and anaplasmosis. In South Africa, co-infestation ...
-
(University of Pretoria, 2013)Thermus bacteria are of special interest because of their ability to live in high temperature environments. Their enzymes exhibit higher and stable activity in industry as compared to mesophilic or synthetic counterparts. ...
-
Comparing biochemical and biophysical methodologies for the characterization of induced cell death (University of Pretoria, 2015)Background: In specific circumstances, the induction of cell death can be an appropriate treatment of disease. Cell death can occur because of internal programming or external stress caused by infection, radiation or ...
-
(University of Pretoria, 2013-06-28)The reusability of active enzyme is important in industrial bio-catalysis applications. This is not readily accomplished with free enzymes. The project investigated a new enzyme immobilization matrix, ReSynTM, and compared ...
-
(University of Pretoria, 2017)First year students at tertiary institutions find themselves in an environment that is both exciting and intimidating. This study explores the dynamics of the classroom where biology students meet an experienced and a ...
-
(University of Pretoria, 2009-06-17)Literature highlights the effects of mycolic acid (MA) fine-structure on biological activity, pathogenicity, virulence and cell wall structure and permeability. Knowledge on MA-structure and how their conformations are ...
-
(University of Pretoria, 2020)Late-stage gametocytes of P. falciparum parasites are responsible for the ongoing human-to-mosquito transmission of malaria disease. To block transmission, novel gametocytocidal compounds are required. It is thus important ...
-
(University of Pretoria, 2017)Functional genomic tools can be used to interrogate unique features of parasite biology that could be marked for future intervention strategies. One such unique biological feature is the atypical cell cycle of the Plasmodium ...
-
(University of Pretoria, 2008-08-05)The polyamines putrescine, spermidine and spermine play essential roles in the proliferation and differentiation of most eukaryotic cells. Inhibition of the polyamine pathway is known to have antitumour and antiparasitic ...
-
(University of Pretoria, 2007-05-02)The high incidence of malaria, coupled to the increasing occurrence of parasite resistance against commonly used anti-malaria drugs and the absence of an effective vaccine, makes the implementation of alternative strategies ...
-
(University of Pretoria, 2020)Diabetes mellitus which is characterized by a high levels of blood glucose is a major source of mortality, morbidity and health costs worldwide. Major gaps exist in efforts to comprehend the burden nationally and globally, ...
-
(University of Pretoria, 2009-09-16)Microarray technology makes it possible to identify changes in gene expression of an organism, under various conditions. The challenge to researchers that employ microarray expression profiling is that once pre-processing ...
-
(University of Pretoria, 2013-05-17)Although conventional two-dimensional (2D) cell culture is convenient for routine work, researchers are turning to three-dimensional (3D) cell culture for more accurate, physiologically representative information on the ...
-
(University of Pretoria, 2013)Nitric oxide is a small diatomic molecule and is part of the nitrogen radical species. As a gas, it diffuses easily across cell membranes and is involved in numerous physiological processes and inflammation. This peculiar ...
