The UFS winners of the Old Mutual Agricultural Student of the Year Competition are Michelle Marais and Wian Visser.

The University of the Free State (UFS) once again produced winners at this year’s Old Mutual Agricultural Student of the Year competition. Michelle Marais, honours student in the UFS Department of Agricultural Economics, and Wian Visser, final-year BScAgric Agronomy student, were top scorers in the Agricultural Economics and Crop Production sections respectively. 

Learning from the best

Apart from the opportunity to compete in their field of study, Michelle and Wian also benefited from the expertise of industry leaders in agricultural economics, animal science, and crop production. They had the opportunity to learn from Dr John Purchase (Agbiz), Dr Dirk Strydom (Grain SA), and Gerhard Schutte (Red Meat Producers’ Organisation), who acted as industry partners and judges during the competition. 

Michelle always had a particular interest in the development of emerging farmers and plans on doing her master’s degree in Agricultural Economics, focusing on emerging wool farmers. “Beyond that, I hope to get an opportunity to work finding solutions to some of the problems facing development in agriculture,” she said. 

Wian also plans on completing his master’s. “Thereafter, I would like to enter the workforce and help the current and future producers to farm better in a changing environment. The ideal would be to remain in a research-oriented position while working full time,” he said. 

Participating with the UFS in this competition, were Stellenbosch University (producing the overall winner in the Animal Science section, Pieter Theron), the University of Fort Hare, North-West University, and the University of Pretoria. As with last year’s competition, the students first had to compete in an initial round at their respective universities, after which eleven finalists went through to the final round held during the ALFA expo at the Afridome in Parys. 

Rewarded for hard work

The winners were announced during a gala dinner at the expo. Besides a green blazer and R1 000 prize money, Michelle and Wian also received an Old Mutual investment portfolio worth R5 000. They furthermore gained exposure on Grootplaas and RSG Landbou and in Plaas Media’s magazines Veeplaas, Stockfarm, and FarmBiz.

According to Dr Frikkie Maré, Academic Head of the Department of Agricultural Economics (UFS), the Old Mutual Agricultural Student of the Year competition provides the ideal opportunity for universities to showcase the quality of their Agricultural students, and thus the quality of their teaching and research practices. 

He said: “In the two years that the competition was hosted, the UFS managed to win the Agricultural Economics and Animal Science divisions in 2018, and the Agricultural Economics and Plant Production divisions in 2019.  We have thus been able to win all three categories over the two years, which can only serve as an indication that the UFS is indeed one of the top Agricultural Science universities in the country.”

Preparing for the workplace

Wian and Michelle both agree that they have received more than just the exposure and funding. 

In her own words, Michelle described the value added: “This competition challenged me to become more aware of current events within the politics, policy, and economic development in the country and the influence on our specific industry. The opportunity to present my findings and opinions on current issues in agriculture to several industry leaders, challenged me to combine the theoretical knowledge gathered in my four years of study with my practical experiences. Applying it to real-world problems and finding possible solutions helped me to realise that I could not have asked for better preparation in the workplace.”

According to Wian, the competition presented him with the opportunity to develop his networking skills and a chance to express his opinion in a professional environment. “It broadened my perception on agriculture by exposing me to different entities in the agricultural community. I also saw different methods and approaches in the sector that I am not necessarily familiar with,” he said. 

Wian believes the UFS has one of the best agricultural faculties in the country and that staff put a lot of effort into preparing students for the world of work. “The Department of Agronomy encourages critical thinking, an essential skill in an ever-changing work environment,” said Wian. He added: “Assessments are not only theoretical, but practical. These practical skills are related to the work required in a work environment. The department also exposes its students to companies, resources, and contacts that are helpful for networking when one enters the workforce.”

According to Michelle, the Department of Agricultural Economics also play their part in preparing students for the job market. “Our assignments always challenged us to contact people in the industry, to do industry research, and to plan practically,” she said. 

Old Mutual has been involved as the name sponsor of this Plaas Media competition since 2018 and has played an active role in promoting and developing the competition.

Imagine that you have been diagnosed with bone cancer and only have six months to live. You are in a wheelchair because the pain in your legs is so immense that you can’t walk anymore – similar to a mechanism eating your bones from the inside.

You are lucky though, since you could be injected with a drug to control the pain so effective that you will be able to get out of the wheelchair within a day-and-a-half and be able to walk again. Real-life incidents like these provide intense job satisfaction to Prof André Roodt, Head of Inorganic Chemistry at the University of the Free State (UFS). The research, which is conducted by the Inorganic Group at the UFS, contributes greatly to the availability of pain therapy that does not involve drugs, but improves the quality of life for cancer patients.

The research conducted by the Inorganic Group under the leadership of Prof Roodt, plays a major role in the clever design of model medicines to better detect and treat cancer.

The Department of Chemistry is one of approximately 10 institutions worldwide that conducts research on chemical mechanisms to identify and control cancer. “The fact that we are able to cooperate with the Departments of Nuclear Medicine and Medical Physics at the UFS, the Animal Research Centre, and other collaborators in South Africa and abroad, but especially the methodology we utilise to conduct research (studying the chemical manner in which drugs are absorbed in cancer as well as the time involved), enhances the possibility of making a contribution to cancer research,” says Prof Roodt.

Technique to detect cancer spots on bone
According to the professor, there are various ways of detecting cancer in the body. Cancer can, inter alia, be identified by analysing blood, X-rays (external) or through an internal technique where the patient is injected with a radioactive isotope.

Prof Roodt explains: “The doctor suspects that the patient has bone cancer and injects the person with a drug consisting of an isotope (only emits X-rays and does no damage to tissue) that is connected to a phosphonate (similar to those used for osteoporosis). Once the drug is injected, the isotope (Technetium-99m) moves to the spot on the bone where the cancer is located. The gamma rays in the isotope illuminate the area and the doctor can see exactly where treatment should be applied. The Technetium-99m has the same intensity gamma rays as normal X-rays and therefore operates the same as an internal X-ray supply.” With this technique, the doctor can see where the cancer spots are within a few hours.

The same technique can be used to identify inactive parts of the brain in Alzheimer patients, as well as areas of the heart where there is no blood supply or where the heart muscle is dead.

Therapeutic irradiation of cancer
For the treatment of pain connected with cancer, the isotope Rhenium-186 is injected. Similar to the manner in which the Technetium-99m phosphonate compound is ingested into the body, the Rhenium-186 phosphonate travels to the cancer spots. Patients thus receive therapeutic irradiation – a technique known as palliative therapy, which is excellent for treating pain. A dosage of this therapy usually lasts for about two months.

The therapy is, however, patient specific. The dosages should correspond with the occurrence and size of cancer spots in the patient’s body. First, the location of the cancer will be determined by means of a technetium scan. After that, the size of the area where the cancer occurs has to be determined. The dosage for addressing total pain distribution will be calculated according to these results.

Technique to detect cancer spots on soft tissue
Another technique to detect cancer as spots on bone or in soft tissue and organs throughout the body is by utilising a different type of irradiation, a so-called PET isotope. The Fluor-18 isotope is currently used widely, and in Pretoria a machine called a cyclotron was produced by Dr Gerdus Kemp, who is a former PhD graduate from the Inorganic Research Group. The F-18 is then hidden within a glucose molecule and a patient will be injected with the drug after being tranquillised and after the metabolism has been lowered considerably. The glucose, which is the ‘food' that cancer needs to grow, will then travel directly to the cancer area and the specific area where the cancer is located will thus be traced and ‘illuminated’ by the Fluor-18, which emits its own 'X-rays'.

In the late 80s, Prof Roodt did his own postdoctoral study on this research in the US. He started collaborating with the Department of Nuclear Medicine at the UFS in the early 90s, when he initiated testing for this research.

Through their research of more than 15 years, the Inorganic Group in the Department of Chemistry has made a major contribution to cancer research. Research on mechanisms for the detection of cancer, by designing new clever chemical agents, and the chemical ways in which these agents are taken up in the body, especially contributes to the development in terms of cancer therapy and imaging, and has been used by a number of hospitals in South Africa.

The future holds great promise
Prof Roodt and his team are already working on a bilateral study between the UFS and Kenya. It involves the linking of radio isotopes, as mentioned above, to known natural products (such as rooibos tea), which possess anti-cancer qualities.
