Prof Motlalepula Matsabisa, Associate Professor in the Department of Pharmacology at the University of the Free State (UFS), has been appointed as the chairperson of the World Health Organisation’s (WHO) Regional Expert Advisory Committee on Traditional Medicines for COVID-19.

Prof Motlalepula Matsabisa, Associate Professor in the Department of Pharmacology at the University of the Free State (UFS), will lead Africa’s fight against the COVID-19 pandemic with his appointment as chairperson of the World Health Organisation’s (WHO) Regional Expert Advisory Committee on Traditional Medicines for COVID-19.

Prof Matsabisa has been chosen over 25 other experts from 27 African countries to head this expert committee tasked with setting up research and clinical trials for COVID-19 and beyond. The committee is also supported by the African Union (AU), the Centers for Disease Control and Prevention (CDC – Africa), and the European and Developing Countries Clinical Trials Partnership (EDCTP).

This committee was established by the WHO and the Africa CDC on 22 July with the aim of providing independent scientific advice and support to countries on the safety, efficacy, and quality of traditional medicine therapies. It is also an effort to enhance research and development of traditional medicines for COVID-19 in Africa.

Looking forward

“This is a huge continental and global responsibility being laid on my shoulders as a chairperson.  I have to keep the committee together and ensure that it delivers on its set mandate and terms of reference.  I need to ensure that the committee helps the continent and region to get the scientific and legislative aspects on traditional medicine development on track.”  

“I have taken this position and responsibility, knowing quite well what it entails. I want to do this for the continent and for the sake of good science of all traditional healers and consumers of traditional medicines on the continent and beyond,” says Prof Matsabisa.

According to Prof Matsabisa, he is looking forward to working with a team of dedicated experts from 27 countries in the African region, and being of help to countries that need assistance with clinical trials, including preclinical work to move to clinical research.

Prof Matsabisa says he is also looking forward to countries asking South Africa to be part of their multi-centre studies in clinical trials for traditional medicines, and to help set up clinical trial teams that include Western-trained clinicians to get into traditional medicine studies. 

The work of the committee

According to Prof Matsabisa, his new position took effect the same day as his appointment and will run as long as COVID-19 is part of our daily lives and even beyond. It entails supporting member states to implement the WHO master plan for clinical trial protocols in order to generate credible data for COVID-19 results, based on traditional medicines. The committee will also coordinate support to member states in the African region to collaborate on clinical trials of traditional medicine-based therapies – elevating standards by pooling expertise in multicentre studies, as well as complying with GCP and good participatory practice guidelines for trials of emerging and re-emerging pathogens.
“The committee will also advise on strengthening the capacity of national medicine regulatory authorities to accelerate the issuance of marketing authorisations for traditional medicine products that have been well researched for safety, efficacy, and quality, as well as to expedite the approval of clinical trials on traditional medicines. This will help to meet the national registration criteria and the WHO norms and standards of quality, safety, and efficacy for the management of COVID-19 and others.”

“It will also provide independent scientific advice to the WHO and other partners regarding policies, strategies, and plans for integrating traditional medicines into COVID-19 responses and health systems,” explains Prof Matsabisa. 

Aiming for the top spot 

Prof Matsabisa has been described as having the third highest research output – something he is not satisfied with. 
“I was disappointed that only one point separated me from the second place. I will push for first place as this is my ultimate aim. My motivation for this is simple – I like what I am doing, I do not take it as a job but do it because I love research.”  

“I always like to tell students that we should be proud to one day see products in the shops that we can relate to and to which we have contributed or that we have made.   This is what drives me and my staff.  I have a beautiful team of students, staff, and postdoctoral fellows who share my vision of research.  We all have a shared vision and strive to be relevant at all times in science research, development, and teaching.”

• Prof Matsabisa was recently part of a national conference with the theme: Harnessing science, technology, and innovation in response to COVID-19: A national and international effort. The conference was hosted by Dr Blade Nzimande, Minister of Higher Education, Science and Innovation, with Pres Cyril Ramaphosa, Dr Zweli Mkhize, Minister of Health, Ebrahim Patel, Minister of Trade, Industry and Competition, Prof Sarah Anyang Agbor, African Union Commissioner for Human Resources, Science and Technology, and Dr Tedros Adhanom Ghebreyesus, Director-General of the World Health Organisation, in attendance.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
