UFS Traditional Medicine
Recardia Schoeman, Scientific Officer in the Department of Pharmacology, gave Prof Paul Waako, Dr Samuel Baker Obakiro, and Dr Richard Oriko Owor from the Busitema University a tour of the department and its laboratories.

Prof Motlalepula Matsabisa, Director of Pharmacology at the University of the Free State (UFS), played host to academics from the Busitema University in Uganda for benchmarking on traditional medicine and to establish collaboration between the two institutions.

Prof Paul Waako, Vice-Chancellor of the Busitema University – who was part of the visiting party – and Prof Francis Petersen, UFS Rector and Vice-Chancellor, signed a collaboration agreement that enables the two institutions to work together and to get involved in the exchange of expertise as part of the collaboration.

Dr Samuel Baker Obakiro, Lecturer of Pharmacology and Therapeutics and Head of the Department of Pharmacology, and Dr Richard  Oriko Owor, a natural products chemist, accompanied Prof Waako on the visit to the UFS from 18 to 21 July, during which they undertook tours of various departments and laboratories, including Pharmacology, Virology, Chemistry, Genetics, Physics, Microbiology, and others. They also visited FARMOVS.

 

Establishing collaboration

Uganda – through their Ministry of Science, Technology, and Innovation – has a national drive to ensure that science contributes to socio-economic development through their major national agenda, which promotes local production, reduces importation, and increases exportation of goods. Dr Monica Musenero Masanza, Minister of Science, Technology, and Innovation, wants to ensure that the capacity of Ugandan scientists to conduct applied research will promote national development and reduce poverty.

Prof Waako said they came to the UFS to establish collaboration, as universities have an obligation to ensure that science improves the socio-economic situation in Africa. They would like to work with the UFS to ensure that science strengthens science in order to serve the people.

“Currently, one of the biggest challenges is the local manufacturing of pharmaceuticals, and that is why we came to the Department of Pharmacology. We need to come together as African universities and use all the existing capacities to transform the lives of our people.”

“African traditional medicine has a lot to offer, and a lot of research has been done, but we have not been able to take it to the level of final commercialisable products. This is the reason of us coming here, we want to create that link to ensure that the science – which has already been identified and established – is able to move to product production,” says Prof Waako.

 

At the right place

They decided to visit the UFS after meeting Prof Matsabisa during his visit to their country’s universities as part of the WHO team.

According to Dr Obakiro, when walking down the corridors of the department, they can see that they are in the right place. “We are also looking at mentorship, as our university is still very young. I am happy and privileged to be here. We cannot succeed on our journey if we do not stand on your shoulders.”

Dr Obakiro said they are also looking at how to set up partnerships between academia and industry, as well as collaboration between the different academic departments, such as pharmacology, chemistry, microbiology, and virology, and how these collaborative initiatives can be effective and efficient to drive their agenda.

In welcoming the colleagues from West Africa, Prof Matsabisa said, “Let’s find a way to crawl together and eventually run together. If you want to move into drug discovery and development, no single scientist can do it alone, it is a multidisciplinary approach. It is a team effort with a shared vision. We have some experience that we can share with you, but we are not perfect, and I think we can learn together.”

NRF grants of millions for Kovsie professors

Two professors received research grants from the National Research Foundation (NRF). The money will be used for the purchase of equipment to add more value to their research and take the university further in specific research fields.

Prof Martin Ntwaeaborwa from the Department of Physics has received a R10 million award, following a successful application to the National Nanotechnology Equipment Programme (NNEP) of the NRF for a high-resolution field emission scanning electron microscope (SEM) with integrated cathodoluminescence (CL) and energy dispersive X-ray spectrometers (EDS).

Prof Bennie Viljoen from the Department of Microbial, Biochemical and Food Biotechnology has also been awarded R1,171 million, following a successful application to the Research Infrastructure Support Programme (RISP) for the purchase of a LECO CHN628 Series Elemental Analyser with a Sulphur add-on module.

Prof Ntwaeaborwa says the SEM-CL-EDS’ state-of-the art equipment combines three different techniques in one and it is capable of analysing a variety of materials ranging from bulk to individual nanoparticles. This combination is the first of its kind in Africa. This equipment is specifically designed for nanotechnology and can analyse particles as small as 5nm in diameter, a scale which the old tungsten SEM at the Centre of Microscopy cannot achieve.

The equipment will be used to simultaneously analyse the shapes and sizes of submicron particles, chemical composition and cathodoluminescence properties of materials. The SEM-CL-EDS is a multi-user facility and it will be used for multi- and interdisciplinary research involving physics, chemistry, materials science, life sciences and geological sciences. It will be housed at the Centre of Microscopy.
“I have no doubt that this equipment is going to give our university a great leap forward in research in the fields of electron microscopy and cathodoluminescence,” Prof Ntwaeaborwa said.

Prof Viljoen says the analyser is used to determine nitrogen, carbon/nitrogen, and carbon/hydrogen/nitrogen in organic matrices. The instrument utilises a combustion technique and provides a result within 4,5 minutes for all the elements being determined. In addition to the above, the machine also offers a sulphur add-on module which provides sulphur analysis for any element combination. The CHN 628 S module is specifically designed to determine the sulphur content in a wide variety of organic materials such as coal and fuel oils, as well as some inorganic materials such as soil, cement and limestone.

The necessity of environmental protection has stimulated the development of various methods, allowing the determination of different pollutants in the natural environment, including methods for determining inorganic nitrogen ions, carbon and sulphur. Many of the methods used so far have proven insufficiently sensitive, selective or inaccurate. The availability of the LECO analyser in a research programme on environmental pollution/ food security will facilitate accurate and rapid quantification of these elements. Ions in water, waste water, air, food products and other complex matrix samples have become a major problem and studies are showing that these pollutants are likely to cause severe declines in native plant communities and eventually food security.

“With the addition of the analyser, we will be able to identify these polluted areas, including air, water and land pollution, in an attempt to enhance food security,” Viljoen said. “Excess levels of nitrogen and phosphorous wreaking havoc on human health and food security, will be investigated.”
