Dr Lisa Komoreng’s research highlights traditional medicinal plant qualities used to deal with diseases like TB and elephantiasis.

The burden that diseases like tuberculosis (TB), lymphatic filariasis (elephantiasis), sexually transmitted infections (STIs), skin infections, and ear, nose and throat (ENT) infections bring to the country, mainly poverty-stricken communities, has prompted Dr Lisa Komoreng to focus her research on traditional medicinal plants.

 

South Africa, says Dr Komoreng, has the third highest number of reported cases and the fifth highest number of estimated prevalent cases, with the second highest burden of drug-resistant TB cases in the world amongst the 22 high-burden countries.

South Africa is burdened
by elephantiasis and treating
it remains a huge problem,
says Dr Lisa Komoreng.

 

“According to the Free State Provincial Strategic Plan (2012-2016), HIV and TB are the leading causes of death in the Province, with TB being the second most leading cause. Our country is also burdened by elephantiasis and treating it remains a huge problem. Patients are often turned away from some of the public hospitals, reasons being that there is no treatment in the country or that the disease needs specialist care. It with this in mind that my research focuses on providing treatment that is cheaper than western medicine, easily accessible, with fewer or no side effects,” she said.

 

“People suffering from elephantiasis are not only physically disabled, but they suffer mental, social and financial losses contributing to stigma and poverty. Some of the drugs used to treat the disease are ineffective against adult parasitic worms, which are the ones that cause the disease, and they also have side effects. Our research in dealing with these diseases enables us to work hand-in-hand with herbalists, traditional healers and people who have indigenous knowledge about the use of traditional medicine. We consult with them in order to acquire information about the medicinal plants that are used to treat and manage those diseases. Once they provide us with information, we collect the plant species together, which we subsequently take to the University herbarium for proper identification of their scientific names and to the laboratory for experiments,” she added.

 

Dr Komoreng is a Senior Lecturer in the Department of Plant Sciences at the Qwaqwa Campus. She has authored and co-authored over 15 research articles and has presented her research at various national and international conferences.  Her research team comprises of 5 MSc and 4 PhD students.

 

The Thuthuka NRF Rating Track (2015 – 2017 and 2018 – 2020) funds the research project on elephantiasis.

Einstein's gravitational waves as creative as Bach's music, says UFS physicist

Profile of the gravitational waves of the colliding black holes.

Prof Pieter Meintjes, Affiliated Researcher in the Department of Physics at the University of the Free State, welcomed the work done by the Laser Interferometer Gravitational-Wave Observatory (LIGO) science team.
 
For the first time, researchers from two of the American Ligo centres, in Washington and Louisiana respectively, observed gravitational waves directly, 100 years after Albert Einstein said they existed. "My study field in astrophysics involves relativistic systems. Therefore, Einstein's view of gravity is crucial to me. I consider the theory as the highest form of human creativity - just like the music of JS Bach. Over the past 100 years, the theory has been tested through various experiments and in different ways.
 
“The discovery of gravitational waves was the last hurdle to overcome in making this absolutely unfaltering. I am therefore thrilled by the discovery. It is absolutely astounding to imagine that the equations used to make the predictions about the gravitational-wave emissions when two gravitational whirlpools collide - as discovered on 14 September 2015 by LIGO - are basically Einstein's original equations that were published way back in 1916 - in other words, 100 years ago.
 
“The LIGO detectors have been operational since the early 1990s, but they had to undergo several stages of upgrades before being sensitive enough to make detections. LIGO is currently in its final stage, and is expected to function at optimal sensitivity only within a year or two. To be able to conduct the measurements at this stage is therefore a fantastic achievement, since much more funding will certainly be deposited in the project,” Prof Meintjes says.

The search for gravitational waves by means of the Square Kilometre Array (SKA) is one of the focus points in research by both Prof Meintjes and PhD student, Jacques Maritz. This involves the study of radio signals from pulsars that might show signs of effects by gravitational waves. They are looking for signs of gravitational waves. The gravitational waves discovered and studied in this manner would naturally vary much more slowly than the signal discovered from the two colliding gravitational waves.
 
The discovery will definitely provide renewed impetus to the Square Kilometre Array (SKA) Project to use the dispersion of pulsar signals, and to search for the impact of gravitational waves on signals as they travel through the universe. According to Prof Meintjes, the SKA will definitely contribute fundamentally to the Frontier research, which will provide a good deal of publicity for the UFS and South Africa, if significant contributions are made by local researchers in this field.
