Prof Ashafa’s research documents plants used by the Basotho in the management of different ailments.
The Phytomedicine and Phytopharmacology Research Programme (PPRP) in the Department of Plant Sciences on the Qwaqwa Campus researches the biological effects of medicinal plants used in the folkloric medicine of the Eastern Free State, particularly to explore the values and contribution of indigenous knowledge systems (IKS) towards broader scientific research. This is according to the programme’s principal investigator and researcher, NRF C2-rated researcher, Professor Anofi Ashafa. 

 “Our research is mainly aimed at documenting plants used by the Basotho in the management of different ailments and to further discover, isolate, and purify active phytoconstituents that are responsible for disease curation or amelioration, thereby assisting in the global promotion of accessible and affordable medication in developing countries,” said Prof Ashafa. 

Since 2012, the PPRP has worked extensively on Basotho medicinal plants (BMP) used as antimicrobials, antioxidants, antidiabetics, antitubercular, anticancer, anthelmintic, and antidiarrheal agents, starting from biological activities up to the  evaluation of the toxicity of these plants for the kidney, liver, and heart functions in order to establish safe dosage parameters. These activities have led to the discovery of four potent antidiabetic biomolecules that are awaiting the processes of patency and commercialisation. Additional outputs include 104 published peer-reviewed articles , 7 postdoctoral fellows, 6 PhDs, 9 master’s, and 16 honours graduates. 

“Our research informs teaching and the development of expertise in ethnobotany, 
phytomedicine, and phytopharmacology in order to contribute to the National Development Plan (NDP) through human capacity development, skills, and knowledge transfer.

The group is also investigating some medicinal plants on the endangered red list of the South African National Biodiversity Institute (SANBI), through micropropagation and field trials as well as proposing conservation strategies to preserve these valuable species.

The PPRP consists of postdoctoral fellows, PhD, master’s, and honours students and research is done in collaboration with several local and international universities as well as the Agricultural Research Council of South Africa.

It is better for Super Rugby teams not to have the ball, which also leads to reduced overall playing time in matches.

This observation is from a study by the University of the Free State on the difference between winning and losing teams. Statistics between 2011 and 2015 show that Super Rugby winning teams kick more and their defence is better.

These statistics were applied by Riaan Schoeman, lecturer in Exercise and Sport Sciences, Prof Derik Coetzee, Head of Department: Exercise and Sport Sciences, and Prof Robert Schall, Department of Mathematics and Actuarial Sciences. The purpose of the study, Changes in match variables for winning and losing teams in Super Rugby from 2011 to 2015, was to observe changes. Data on 30 games (four from each team) per season, supplied by the Cheetahs via Verusco TryMaker Pro, were used.

About two minutes less action
“We found that the playing time has decreased. This is the time the ball is in play during 80 minutes,” says Schoeman. In 2011, the average playing time was 34.12 minutes and in 2015 it was 31.95.

“The winning team has less possession of the ball and doesn’t want it. They play more conservatively. They dominate with kicks and then they play,” says Prof Coetzee, who was the conditioning coach for the Springboks in 2007 when they won the World Cup.

Lineouts also more about kicking
As a result, the number of line-outs also increased (from 0.31 per minute in 2011 to 0.34 in 2015) and the winning teams are better in this regard.

“The winning team has less possession of the ball
and doesn’t want it. They play a more conservative
game. They dominate with kicks and then they play.”

Schoeman believes that rule changes could also have contributed to reduced playing time, since something like scrum work nowadays causes more problems. “When a scrum falls, the time thereafter is not playing time.”

According to Prof Coetzee, rucks and mauls have also increased, (rucks from 2.08 per minute in 2011 to 2.16 in 2015 and mauls from 0.07 per minute in 2011 to 0.10 in 2015). “The teams that win, dominate these areas,” he says.
