Odontogenic myxoma: a clinicopathological study in a South African population
(Blackwell, 2016)Background: Odontogenic myxoma is a benign, locally aggressive neoplasm of the jaws. Prevalence rates range between 0.5% and 17.7% of odontogenic tumours. There are few reports in the literature on this lesion in African ... -
Oestrogen, testosterone, cytotoxin and cholinesterase inhibitor removal during reclamation of sewage to drinking water
(Water Research Commission, 2013)Namibia is the driest sub-Saharan country in Africa. Namibia’s capital, Windhoek, reclaims sewage water for domestic use at the Goreangab Water Reclamation Plant (GWRP). Risks associated with sewage effluent and reclaimed ... -
Oral colonization of Gram-negative anaerobes as a risk factor for preterm birth
(Landes Bioscience, 2011)Preterm birth significantly impacts on neonatal morbidity and mortality and is apparently increasing worldwide. Several studies have attempted to define a causative role for periodontal disease in adverse pregnancy ... -
Over-expression of severe acute respiratory syndrome coronavirus 3b protein induces both apoptosis and necrosis in Vero E6 cells
(Elsevier, 2006)The genome of the severe acute respiratory syndrome coronavirus encodes for eight accessory viral proteins with no known homologues in other coronaviruses. One of these is the 3b protein, which is encoded by the second ... -
Overexpression of 7a, a Protein Specifically Encoded by the Severe Acute Respiratory Syndrome Coronavirus, Induces Apoptosis via a Caspase-Dependent Pathway
(American Society for Microbiology, 2004)Besides genes that are homologous to proteins found in other coronaviruses, the severe acute respiratory syndrome coronavirus genome also contains nine other potential open reading frames. Previously, we have characterized ... -
Preliminary study on the effect of sugar cane (Saccharum officinarum) molasses on steroidogenesis in testicular cell cultures
(Academic Journals, 2010)Blackstrap molasses has been used for centuries in the preparation of food products and have also been used to treat numerous ailments such as high blood pressure, arthritis, ulcers, dermatitits, eczema, constipation, ... -

Proteomic mechanisms of drug resistance in Candida cell membrane fractions
(International Association for Dental Research, 2014)INTRODUCTION: The African continent has the highest burden of HIV infection, accounting for approximately 65% of new infections globally. Oral candidiasis is a major cause of increased morbidity in HIV-infected individuals ... -
Quantification and identification of sperm subpopulations using computer-aided sperm analysis and species-specific cut-off values for swimming speed
(Taylor & Francis, 2013)Motility is an essential characteristic of all fl agellated spermatozoa and assessment of this parameter is one criterion for most semen or sperm evaluations. Computer-aided sperm analysis (CASA) can be used to measure ... -
Reconstruction of major maternal and paternal lineages of the Cape Muslim population
(Sociedade Brasileira de Genética, 2013)The earliest Cape Muslims were brought to the Cape (Cape Town - South Africa) from Africa and Asia from 1652 to 1834. They were part of an involuntary migration of slaves, political prisoners and convicts, and they ... -
The relationship between seminal leukocytes, oxidative status in the ejaculate, and apoptotic markers in human spermatozoa
(Taylor & Francis, 2013)The aim of this study was to investigate the relationship between seminal leukocytes, reactive oxygen species (ROS) production in the ejaculate, and markers of apoptosis in human spermatozoa. Semen samples were collected ... -
Relative contribution of various chronic diseases and multi-morbidity to potential disability among Dutch elderly
(2018, 2018)BACKGROUND: The amount of time spent living with disease greatly influences elderly people’s wellbeing, disability and healthcare costs, but differs by disease, age and sex. METHODS: We assessed how various single and ... -
Risk factors of preterm delivery of low birth weight (plbw) in an African population
(Academic Journals, 2010)More than 20 million infants in the world (15.5% of all births) are born with low birth weight. Ninety-five percent of them are in developing countries. The objective of this study was to examine different factors which ... -

The role of Severe Acute Respiratory Syndrome (SARS)-Coronavirus Accessory Proteins in Virus Pathogenesis
(MDPI, 2012)A respiratory disease caused by a novel coronavirus, termed the severe acute respiratory syndrome coronavirus (SARS-CoV), was first reported in China in late 2002. The subsequent efficient human-to-human transmission of ... -
Rutin as a potent antioxidant: implications for neurodegenerative disorders
(Hindawi Publishing Corporation, 2018)A wide range of neurodegenerative diseases (NDs), including Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, and prion diseases, share common mechanisms such as neuronal loss, apoptosis, mitochondrial ... -
The scientific merit of Carpobrotus mellei L. based on antimicrobial activity and chemical profiling
(Academic Journals, 2006)Species of the genus Carpobrotus are similar in appearance and have been used for medicinal purposes over many generations. Carpobrotus mellei is endemic to the south-Western Cape of South Africa, and also used for various ... -
Seasonal variation of citrinin in traditionally brewed African beer
(Academic Journals, 2013)A seasonal study on citrinin concentrations in traditional beer was conducted using a standardised enzyme-linked immunosorbent assay. Representative samples of indigenous South African beer were collected during the hot, ... -
The Severe Acute Respiratory Syndrome Coronavirus 3a Protein Up-Regulates Expression of Fibrinogen in Lung Epithelial Cells
(American Society for Microbiology, 2005)Here we analyzed the gene expression profile of cells that stably express the severe acute respiratory syndrome coronavirus (SARS-CoV) 3a protein to determine its effects on host functions. A lung epithelial cell-line, ... -
Severe acute respiratory syndrome coronavirus protein 7a interacts with hSGT
(Elsevier, 2006)Severe acute respiratory syndrome coronavirus (SARS-CoV) 7a is an accessory protein with no known homologues. In this study, we report the interaction of a SARS-CoV 7a and small glutamine-rich tetratricopeptide repeat-containing ...
