In Sub-Saharan Africa there is an urgent need to sustain and improve the quality of its food resources. Poverty eradication features high on the agenda of a number of world health organisations, while the number of underweight ...

Understanding the dynamics and mechanism of protein folding continues to be one of the central problems in molecular biology. Peptide folding experiments characterize the dynamics and molecular mechanisms of the early ...

Information regarding the nutritional value of wild food plants in Africa and current information varies from source to source. Prior to commercialization of wild foods the nutritional, ethnobotanical, medical, chemical, ...

Riboflavin (vitamin B2), an essential water-soluble vitamin is commercially produced because it cannot be synthesized by vertebrates. Although this vitamin is produced chemically, bioproduction is a better option since it ...

The provision of safe and sanitary water is a constitutional right and above all, a necessity of life. As a result of the rapid urbanisation and the past policies of apartheid, a large population of South Africa dwell in ...

Previous studies indicate that a mutation in the non-oncogenic p53 gene is epidemiologically linked to human HCC (Ozturk, 1991; Chan et al., 2003). Hsu et al. (1991) found this link in Chinese, South African and Asian ...

A comparative thermostability analysis of different partially purified xylanases from Rhodothermus marinus, Bacillus halodurans, Thermomyces lanuginosus and Pulpzyme HC was studied using differential scanning fluorometry ...

This study involved a series of molecular dynamics (MD) simulations applied to case studies of small and medium-size polypeptides to assess the thermodynamics of their folding characteristics. Peptide folding is a complex ...

Unprecedented cycloaddition reactions of azatrienes (1) with sulfene leading to the synthesis of functionalized thiazine-dioxide derivatives (5) are described. The reactions were found be highly regioselective resulting ...
