Variability at Human Immunodeficiency Virus Type 1 Subtype C Protease Cleavage Sites : an indication of viral fitness

Cassol, Sharon; De Oliveira, Tulio; Engelbrecht, Susan; Janse van Rensburg, Estrelita; Gordon, Michelle; Bishop, Karen; Zur Megede, Jan; Barnett, Susan W. (American Society for Microbiology, 2003-09)

Naturally occurring polymorphisms in the protease of human immunodeficiency virus type 1 (HIV-1)subtype C would be expected to lead to adaptive (compensatory) changes in protease cleavage sites. To test this hypothesis, ...
Effects of sub-lethal concentrations of pneumolysin on the proinflammatory activities of human neutrophils in vitro

Cockeran, Riana (University of Pretoria, 2005-09-22)

The Streptococcus pneumoniae-derived toxin, pneumolysin, has been reported to augment neutrophil-mediated inflammatory responses in murine models of experimental infection of the airways, and to favour invasive pneumococcal ...

Motivation: Genetic analysis of HIV-1 is important not only for vaccine development, but also to guide treatment strategies, track the emergence of new viral variants and ensure that diagnostic assays are contemporary and ...
Membrane potential and intracellular cyclic AMP as regulators of calcium homeostasis in formyl peptide-activated human neutrophils : lessons from chronic granulomatous disease

Tintinger, Gregory Ronald (University of Pretoria, 2005-11-07)

Neutrophils playa key role in the systemic inflammatory response which may lead to serious tissue injury and multiple organ dysfunction. In this setting, activated neutrophils, largely in response to tumour necrosis ...
Absence of Helicobacter pylori within the oral cavities of members of a healthy South African community

Olivier, Brenda J.; Bond, Robert P.; Van Zyl, Walda B.; Delport, Maraliese; Slavik, Tomas; Ziady, Christopher; Terhaar sive Droste, Jochim S.; Lastovica, Albert; Van der Merwe, Schalk Willem (American Society for Microbiology, 2006-02)

Our study aimed to evaluate the oral cavity as a reservoir from where Helicobacter pylori may be transmitted. Histology and PCR amplification were performed. Eighty-four percent of the stomach biopsies tested positive; ...
