Five PhDs for Chemistry group at June 2018 graduation
Pictured here are the Department of Chemistry graduates and their promoters/ co-promoters. From the left are: Dr Alebel Belay, Dr Dumisani Kama, Dr Orbett Alexander, Dr Pennie Mokolokolo and Dr Pule Molokoane; back: Prof Andreas Roodt, Dr Marietjie Schutte-Smith, Dr Alice Brink and Dr Johan Venter. Prof Roodt was either promoter or co-promoter to four of the graduates, while Prof Deon Visser (promoter; not present) and Dr Alice Brink (co-promoter) supervised Dr Orbett Alexander.

What is the common factor among metal extraction from mineral reserves, the treatment of cancer, and nanomaterials in cellular phones? The answer is Chemistry. 

For the first time since the Department of Chemistry at the University of the Free State (UFS) was founded some 114 years ago, a single research group in Chemistry delivered five PhD students.  This was achieved in the division of Inorganic Chemistry at the 2018 Winter graduation ceremony by the group under leadership of Prof Andreas Roodt and senior colleagues, Drs Johan Venter, Alice Brink and Marietjie Schutte-Smith. Prof Deon Visser, a former group member, was promoter for one of the students. 

The five graduandi are Drs Alebel Belay, Dumisani Kama, Pennie Mokolokolo, Pule Molokoane and Orbett Alexander. Their research involved the use of special chemical groups which are attached to metals such as platinum, rhodium, niobium, technetium and rhenium to create compounds with special pre-selected properties. 

The combination of these special groups with the metals allow many different potential applications – all adding value. These include metal extraction from South Africa’s rich mineral reserves, the treatment of diseases such as cancer, the diagnosis of heart and brain damages, nanomaterials which are used in cellular phones, catalysts to produce cleaner petrol, special light devices which by themselves ‘glow in the dark’, and more. 

Three of the students completed part of their research in Switzerland.

UFS doctors fight childhood cancer

Of 23 paediatric oncology specialists nationally, Prof David Stones and Dr Jan du Plessis of the University of Free State are the only ones in the province.

Committed to giving holistic care to their patients, the two doctors specialise in all types of childhood cancers, the most common being leukaemia, brain tumour, and nephroblastoma.

They describe the childhood malignancy as a lethal disease, unpredictability being its harshest trait. “With cancer, you can just never know. It precipitates and multiplies, and leads to the failure of other organs. You can just always hope, and keep trying,” said Du Plessis.

The paediatric oncology unit of the Universitas Academic Hospital, their unit, is the liveliest floor in the entire building. It is also the third busiest in South Africa, serving a demographic that spans the Free State and Northern Cape, as well as parts of North West, Eastern Cape and Lesotho.

Each year, the unit receives more than 100 new childhood cancer patients. In 2015, the unit had 113 newly diagnosed patients, an increase from 93 in 2014.

Lack of knowledge poses a serious challenge
According to the two experts, the lack of insight and awareness of the disease remain a big challenge to fighting it. “It is frustrating. Parents and family members don’t know anything about it. Nurses and doctors aren’t always clinically trained to pick up the early warning signs. By the time a diagnosis is made, life and death is on a 50% margin,” Stones said.

Poverty, a lack of resources, overcrowding and a range of health issues are other factors that have a profound effect on the diagnosis and treatment of the disease.

Making a contribution that will last
With a desire to see an improvement on life outcomes in the health sector, the team is focusing on educating the country’s doctors of tomorrow. Their unit is the only one in the country that actively involves medical students in an oncology unit, giving them practical experience and exposure to the individual cases each patient presents. They have also produced a substantial amount of research literature on childhood malignancies in South Africa as a developing country.

Driven by passion to see a better South Africa
The doctors are passionate about the work they do, and remain hopeful there will be a change in the incidence of childhood cancer   not just in decreased levels of the disease, but also in the overall state of well-being of young South Africans.
