Reciprocal chromosome painting among human, aardvark, and elephant (superorder Afrotheria) reveals the likely eutherian ancestral karyotype
The Afrotheria, a supraordinal grouping of mammals whose radiation is rooted in Africa, is strongly supported by DNA sequence data but not by their disparate anatomical features. We have used flow-sorted human, aardvark, ...
The establishment of sperm morphology satellite training laboratories in Africa
Discrepancies in the results of semen analysis can be caused by a variety of factors, for example, a microscope for semen analysis can be situated in the practice of an urologist, cytologist or microbiologist, or even in ...
Outcome of children treated for cancer in the republic of Namibia
The data of a survey undertaken to record all cases of childhood cancer in Namibia from 1983 to 1988 were analyzed to estimate 5-year survival rates. The projected survival rate for 150 children with cancer was 37% with ...
AIDS defining lymphomas in the era of highly active antiretroviral therapy (HAART) - An African perspective
The intermediate to high grade B-cell non-Hodgkin lymphomas are now one of three malignant AIDS defining conditions. The others being Kaposi's sarcoma and cervical carcinoma. While co-infection with oncogenic agents including ...
External genital human papillomavirus prevalence and associated factors among heterosexual men on 5 continents
Background. We examined the baseline prevalence of penile, scrotal, and perineal/perianal human papillomavirus (HPV) in heterosexual men (HM). We also evaluated baseline characteristics of HM to assess factors associated ...

The spectrum of anorectal malformations in Africa
Anorectal malformations (ARM) remain a significant birth defect with geographic variation in incidence, individual phenotypes and regional geographic subtypes. Although early studies indicated a low incidence in Black ...
Genome-wide analysis of the structure of the South African Coloured Population in the Western Cape
Admixed populations present unique opportunities to discover the genetic factors underlying many multifactorial diseases. The geographical position and complex history of South Africa has led to the establishment of the ...
Are Polymorphic Markers within the α-1-Antitrypsin Gene Associated with Risk of Human Immunodeficiency Virus Disease?
We sought to determine whether variants of the human α-1-antitrypsin (AAT) gene, also known as "PI," or "SERPINA1," are associated with human immunodeficiency virus (HIV) infection in 2 African-based populations from ...
Positive and negative symptoms in affected sib pairs with schizophrenia: Implications for genetic studies in an African Xhosa sample
Careful phenotyping and the identification of subtypes of schizophrenia can contribute significantly to the success of genetic studies in schizophrenia. The phenomenology of schizophrenia in affected sib pairs has been ...
