Objective: The purpose of this study was to examine the relationship between fat patterning, age and body composition, among urban South African children in Pretoria, Central. Methods: Samples for the study comprised 1136 participants (548 boys and 588 girls) and 581 black and 555 white drawn from 12 primary schools in Pretoria Central. Anthropometrical measurements include stature, body mass and eight skinfolds: triceps, subscapular, biceps, supraspinal, abdomen, front thigh, iliac crest and medial calf. Principal components analysis technique was applied to examine the components loadings. An eigenvalue of >1.0 was retained for analysis. Pearson's correlation coefficient was used to determine the relationship of fat patterning scores, age and body composition measures. Findings: Three principal components emerged. The first principal component was a size component (fatness), accounting for 62.3% variance. The second component (central-peripheral patterning) accounted for the total variance of 14.1%. The third component (lower trunk-upper extremity) of relative subcutaneous fat distribution, explained about 10.2% of the total residual variance. Overall, the three components account approximately for 87.0% of the total variance. The correlation coefficients indicating probabilities demonstrated that the overall body fatness (PC1), but not PC2 or PC3 was significantly correlated with body mass index (r=0.745, P<0.01), FM (r=0.672, P<0.01), fat-free mass (r=0.583, P<0.01), Percentage body fat (r=0.701, P<0.01) and children's age (r=0.062, P<0.05). Conclusion: The central-peripheral and upper-lower body extremity fat patterning components are discernible among the sample of South African children in Pretoria. The results indicated that principal component 1, but not 2 and 3 was significantly correlated with body composition variables and age, suggesting that component 1 is truly an indicator of total body fatness and not fat patterning. © 2013 by Pediatrics Center of Excellence, Children's Medical Center, Tehran University of Medical Sciences, All rights reserved.

An ethnobotanical survey was carried out in the former Transkei homeland to document the unwritten knowledge related to traditional uses of medicinal plants. The indigenous people of Transkei, Eastern Cape, South Africa depend on the natural plant resources from their environment for medicine, food, pastoral, cultural and religious needs. This area, mainly inhabited by the Xhosa people, has remained ethnobotanically unexplored until recently. The present investigation among the herbalist, traditional doctors, herb traders, tribal priests and other knowledgeable local people documented medicinal and other uses of 35 species of traditional medicinal plants belonging to 34 genera and 26 families. The study recorded the local, scientific and family names of the medicinal plants. The plant parts used and method of administration are also presented in this paper. This firsthand information points out the importance of local flora to tribal groups and non-tribal people of Transkei. In spite of western influence, the Xhosa people of Transkei still believe in the efficacy of herbal medicine, and prefer to use these traditional remedies. Further, scientific study will be required for validation of these ethnomedicines. Source

This study assessed the knowledge, attitude and practices (KAP) of learners on issues related to water, sanitation and hygiene in selected schools in Vhembe District, South Africa. The methodology relied on a questionnaire, an inspection of sanitary facilities and discussion with the school authorities. The data was analyzed using the Statistical Package for Social Science. The study revealed that the level of knowledge about waterborne diseases was relatively high (76.7 ± 1.75%), but knowledge on transmission routes was inadequate. The majority of the respondents had no knowledge when it comes to water-based diseases and their prevention (78.4 ± 1.71%).The attitude and practice on hygiene was also found to be high (91.40 ± 1.16%). Some schools from the urban area had proper handwashing facilities, but there was no soap available. The borehole water quality for rural schools appeared clear, but the microbial quality was unknown. The water supply and sanitation facilities were inadequate in rural schools, with no handwashing areas and no sanitary bins for girls. Some schools had toilets with broken doors which did not offer privacy. The only water tap, located at the centre of the school premises, was not enough for the whole school community. Source

Senegalia lotterii is a proposed new species to science, characterized by its paired prickles pointing straight ahead or slightly upwards one of which is often lost due to malformation. This species was found to be a distinct edaphic entity, endemic to the Barberton Centre of Endemism. © 2013 Magnolia Press. Source

Toxicological and Environmental Chemistry | Year: 2014

A laboratory batch experimental study has been carried out to evaluate the adsorption capacity of selected metal species in acid mine drainage (AMD) by bentonite clay. Bentonite clay was mixed with simulated AMD at specific solid–liquid (S/L) ratios and agitated in a reciprocating shaker and adsorption of selected toxic metals assessed over time. Cation exchange capacity varied from 1140 to 1290 meq kg−1. Contact of AMD with bentonite leads to increase in pH and a possible reduction in electrical conductivity and total dissolved solids. At constant agitation time of 60 min, the pH increased with dosage of bentonite. Removal of Mn2+, Al 3+, and Fe3+ was observed to be greatest at 60 min of agitation. Bentonite clay exhibits high adsorption for Al3+ and Fe3+ at concentration less than 300 mg L−1, while the capacity for Mn2+ was observed to be lower. Adsorption capacity for SO4 2− was low with a great percentage of the SO4 2− remaining in solution. Adsorption capacity of bentonite with more complex formulated AMD and gold tailing leachates was low for Fe3+, Al3+, and Mn2+. This indicates that optimum adsorption of bentonite clay is dependent on the chemistry of the AMD and its application might be site specific. © 2014, © 2014 Taylor & Francis. Source
