Prof Marian Tredoux is a geochemist and lecturer in the Department of Geology at the University of the Free State (UFS). Her research interests are rocks, particularly the chemistry of rocks and the minerals they are composed of – chemicals similar to those found in laboratories, although they occur in nature.
Prof Tredoux started her research career at the University of the Witwatersrand (Wits), after which she spent a number of years at the University of Cape Town (UCT). For the past 11 years, she has been at the UFS, which has brought her in close proximity of her primary field-research area in Barberton. This fascinating part of the country has been the focus of her research for 30 years. She has always been intrigued by the earth's crust in this area, which she describes as "very old, very strange, and very interesting".
Prof Tredoux has been collaborating with colleagues and peers overseas in an attempt to unravel the intricacies of this unusual geological area. Some of these colleagues recently discovered a new mineral in one of the rock formations of the Barberton mountain range. They decided to name the mineral after Prof Tredoux, dubbing it tredouxite. "I am very honoured by this, and very grateful that all these years of collaboration are being acknowledged," Prof Tredoux said.
HIV Cure – Just another fantasy?
2016-07-27
Twenty-years ago, after a person had been diagnosed with HIV, their lifespan did not exceed three years, but thanks to the success of antiretroviral therapy programmes, life expectancy has risen by an average of ten years. However, is antiretroviral therapy always going to be for life? This is the societal issue that Professor John Frater, addressed in his talk at the University of the Free State. He is an MRC Senior Clinical Fellow, Associate Professor and Honorary Consultant Physician in Infectious Diseases at Oxford University.
Antiretroviral medicine therapeutic
The discovery of antiretroviral therapy - the use of HIV medicines to treat the virus - has had a positive effect on the health and well-being of people living with it, improving their quality of life. Unfortunately, if treatment is stopped, HIV rebounds to the detriment of the patient. Now, research has shown that some patients, who are treated soon after being infected by HIV, may go off treatment for prolonged periods. Work is being done to predict who will be able to stop treatment.
“The difference made by starting treatment earlier is enormous. Delaying treatment is denying yourself the right to health,” Professor Frater says. However, this does not mean that the virus is cured. “A person can live for ten years without being on HIV treatment, but is that enough?” he went on to ask.
Healthy lifestyles encouraged
The National Department of Health will adopt a test and treat immediately strategy later this year to improve patient health and curb the spread of HIV. ,This is another reason why everybody should know their status and start treatment as soon as possible.
Search for a cure continues
More research is being conducted to establish whether HIV can be eradicated. Remission gives hope that a permanent cure may be found eventually. “Will a cure for HIV ever be found? Time will tell,” he concluded.
