Two South African government departments have granted the University of the Free State’s Department of Pharmacology a combined amount of R15 million for the establishment of four tea farms in the disadvantaged communities in the North West and Eastern Cape Communities.

The head of the project Prof Motlalepula Matsabisa at the Department of Pharmacology said that that Department of Environmental Affairs (DEA) has granted an amount of R10 million for the community research in the respective provinces.

This grant is a top up to the R5 million they received from the Department of Science and Technology for the “community implementation on indigenous health infusions or teas as commonly known.”

The DEA will in the near future sign a Memorandum of Agreement (MOA) with the university.


Tea project set to empower communities


“The project is to implement and build structures in the four communities we work with in the North West and Eastern Cape,” he said.

The identified areas for the project are in the Eastern Cape towns of Alice and Idutywa as well another two North West communities in Zeerust.

Prof Matsabisa indicated that the project will be a manifestation of “how science can contribute to economic growth, poverty alleviation and job creation.” 

“It was very interesting to have discovered that some French and German companies have already displayed interest in the projects,” he said.

He stated that a project of this nature is a good initiative by the UFS and it will also show that the university’s research activities are national. “We have been researching and developing indigenous teas which have now attracted interest locally and internationally by huge companies such as Nestle, Tiger Brands, Moringa World etc,” he said. 


Taking it slowly


At the initial stages of the tea farming project, Prof Matsabisa said they would start in small portions of utilising five hectares in each of the four projects and as the project gains momentum, they would expand.

Prof Matlabisa said that an environmental impact assessment has already been conducted and they were waiting for the DEA to give them a go ahead for the land preparations.

Three heart-valve studies which have been developed at the Robert WM Frater Cardiovascular Research Centre at the School of Medicine at the University of the Free State (UFS) were recently presented in Monte Carlo at the conference of the prestigious global Heart Valve Society (HVS).

These studies are all headed by Prof Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS, and Manager of the Robert WM Frater Cardiovascular Research Centre.
Prof Smit says the HVS is a combination of the former heart-valve societies of Europe and the US. “Studies on heart-valve disease, heart-valve-related products and operations, as well as the design and development of new valves were presented. There are both clinical and development divisions.

He says the study in which the hemodynamics of their redesigned mechanical poppet valve was compared to a commercial bi-leaflet mechanical heart valve, was named as the best poster presentation in the experimental valve development and numerical flow dynamics division. The study, which was presented by Kyle Davis, mechanical engineer at the centre, competed against some of the best heart-valve research units in the world.

The redesigned valve, based on the 1960s Cape Town poppet valve, has the potential to provide a low-cost solution for mechanical heart-valve replacement. It is possible to produce the titanium ring with 3-D printers and is, together with the silicon poppet valve, extremely inexpensive compared to current mechanical valve-manufacturing processes.
The advantages of this valve over current mechanical valves is that, due to the effective and laminar flow characteristics, as well as the simple locking mechanisms, there is a reduced chance of valve thrombosis, and the need for anti-clotting drugs is therefore limited.

It was also confirmed that the new valve more than meets the published FDA (Federal Drug Agency) requirements, which determine the minimum standards of valves for human use in the US.

The redesigned valve also has a very low platelet activation impact, which is responsible for platelet thrombosis and leads to valve thrombosis or strokes. This valve is another heart-valve project by the centre, which is also in the process of evaluating a tri-leaflet polyurethane valve developed by them.
