Benefit-sharing with human participants in health research in South Africa: A call for clarity.

This study critically examines the concept of benefit-sharing in the context of health research involving human participants in South Africa, identifying a significant gap in the precision and application of terminology. It introduces a new terminological framework designed to provide clarity and facilitate standardisation in both national and international discourse on benefit-sharing. The analysis extends to the complex legal landscape in South Africa, highlighting the nuances of mandated, permitted, and prohibited practices of benefit-sharing across various statutes.

Introducing dynamic consent for improved trust and privacy in research involving human biological material and associated data in South Africa.

Biomedical research using human biological material and data is essential for improving human health, but it requires the active participation of many human volunteers in addition to the distribution of data. As a result, it has raised numerous vexing questions related to trust, privacy and consent. Trust is essential in biomedical research as it relates directly to the willingness of participants to continue participating in research.

Medicine and the Law.

Medico-legal claims in the South African health sector have markedly increased since approximately 2007. This is noteworthy as money spent on these claims from the public health budget, is money which should have been spent on the healthcare priorities identified in the National Department of Health Strategic Plan. As such, it becomes important to understand why these claims have shown drastic increases.

Large increase in disulphide bonds containing cytosol proteins after chronic cadmium administration, estimated in isolated rat liver cells.

Using histochemical staining, followed by cytophotometric quantitation of disulphide bonds and total protein in isolated liver cells of rats treated for a long time with low doses of CdCl2, a large increase in disulphide bonds containing proteins could be demonstrated in cells of one ploidy class. This increase seems to be due to an increase in high molecular weight (HMW) cytosol proteins as estimated biochemically. They probably represent polymers of metallothionein.

Autoradiographic demonstration of the copper-accumulating tissues in mice with a defect homologous to Menkes' Kinky Hair disease.

Mutated Brindled mice have a genetic defect homologous to the human disorder Menkes' or Kinky Hair disease. These animals were used to survey the tissues in which copper accumulates as result of this defect. Heterozygous and unaffected animals were i.
