Nutrition, oral health and the young child
(Wiley Open Access, 2007)
Oral health is integral to general health and essential to well-being and quality of life. Socio-behavioural and environmental factors play a significant role in oral disease and oral health.Dental caries is a global disease ...
A low-cost flow cytometric assay for the detection and quantification of apoptosis using an anionic halogenated fluorescein dye
(Future Science Group, 2008)
We describe here a technical improvement of an established colorimetric method used to detect and measure the occurrence of apoptosis in mammalian cells during in vitro cell culture. This assay uses an anionic halogenated ...
Should subsistence agriculture be supported as a strategy to address rural food insecurity?
(Taylor and Francis Group, 2009)
At first glance South Africa’s black farming sector appears to contribute rather
minimally to overall agricultural output in South Africa. However, despite the
complexity involved in this sector and the often marginal ...
Development of infectious transcripts and genome manipulation of black queen-cell virus of honey bees
(Microbiology Society, 2002)
The South African isolate of Black queen-cell virus (BQCV), a honey bee virus, was previously found
to have an 8550 nucleotide genome excluding the poly(A) tail. Its genome contained two ORFs, a
5«-proximal ORF encoding ...
Foetal alcohol syndrome: A cephalometric analysis of patients and controls
(Oxford University Press, 2006)
Foetal alcohol syndrome (FAS) consists of multi-system abnormalities and is caused by the
excessive intake of alcohol during pregnancy. The teratogenic effect of alcohol on the human foetus
has now been established beyond ...
FRAGS: Estimation of coding sequence substitution rates from fragmentary data
(BMC, 2004)
Rates of substitution in protein-coding sequences can provide important insights into evolutionary processes that are of biomedical and theoretical interest. Increased availability of coding sequence data has enabled ...
Responding to the crisis in sub-Saharan Africa: The role of nutrition
(Cambridge University Press, 2006)
In the chapter dealing with education and health, the report of the influential
Commission for Africa prioritises basic health systems, HIV/AIDS, malaria and
tuberculosis. In contrast, nutrition is given less than half ...
Improving the coverage of the PMTCT programme through a participatory quality improvement intervention in South Africa
(BMC, 2009)
Despite several years of implementation, prevention of mother-to-child transmission (PMTCT) programmes in many resource poor settings are failing to reach the majority of HIV positive women. We report on a data driven ...
The contribution of exon-skipping events on chromosome 22 to protein coding diversity
(Cold Spring Harbor Laboratory Press, 2001)
Completion of the human genome sequence provides evidence for a gene count with lower bound 30,000–40,000. Significant protein complexity may derive in part from multiple transcript isoforms. Recent EST based studies have ...
Scaling up health promotion interventions in the era of HIV/AIDS: Challenges for a rights based approach
(Oxford University Press, 2005)
A sustained scaled up response to global public health
challenges such as HIV/AIDS will require a functioning and
efficient health system, based on the foundation of strong
primary healthcare. Whilst this is necessary, ...
