Traditionally, the success of a researcher is assessed by the number of publications he or she publishes in peer-reviewed, indexed,
high impact journals. This essential yardstick, often referred to as the impact of a ...
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 ...
Is human Immunodeficiency Virus (HIV) stage an independent risk factor for altering the periodontal status of HIV-positive patients? A South African study
(BioMed Central, 2013)
Background: The immunosuppresion in HIV patients makes them highly susceptible to microbial infections. The
aim of the study was to establish whether HIV stage (as depicted by CD4+ T lymphocyte counts) could
independently ...
Strengths and limitations of different Chromogenic Media for the identification of Candida species
(Scientific & Academic Publishing, 2012)
The treatment of invasive candidiasis and other Candida infections with the appropriate antifungal agent is assisted by the identification of Candida isolates to the species level. Rapid and accurate methods of differentiation ...
Drug susceptibility profiles of Candida species isolated from the oral mucosa of HIV-positive West African patients using the TREK Sensititre system
(2013)
BACKGROUND: Candida infections are a common cause of death in
immunocompromised patients. The prevalence and anti-mycotic
drug susceptibility profiles of Candida species from Cameroon in
Africa are unavailable. This ...
Characterisation of human coronavirus-NL63 nucleocapsid protein
(Academic Journals, 2012)
Coronavirus N is a multifunctional protein that plays an essential role in enhancing the efficiency of virus transcription and assembly. This manuscript reports the analysis of HCoV-NL63 N protein by comparing the amino ...
Antimicrobial-resistant Klebsiella species isolated from free-range chicken samples in an informal settlement
(Termedia Publishing House, 2012)
Sub-therapeutic doses of antimicrobial agents are administered
routinely to poultry to aid growth and to prevent disease, with prolonged exposure
often resulting in bacterial resistance. Crossover of antibiotic resistant ...
The impact of sperm DNA damage in assisted conception and beyond: recent advances in diagnosis and treatment
(Elsevier, 2013)
Sperm DNA damage is a useful biomarker for male infertility diagnosis and prediction of assisted reproduction outcomes.

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 ...
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 ...
