2019 is the year of the national general elections in South Africa – 8 May is when South Africans will have an opportunity to vote and to impact change, hopefully for the better.  But the beginning of 2019 saw the resurfacing of student protests, mainly driven by issues of registration, challenges associated with the National Student Financial Aid Scheme (NSFAS), student accommodation, safety of students (off-campus), insourcing, and various other issues influenced by local institutional context.
  
Challenges for university vice-chancellors

Our Constitution promotes protest, but emphasises the peaceful nature thereof, and that it should not infringe on the rights of others or damage property.  However, the protests experienced by the majority of higher-education institutions in South Africa in 2019 was exactly the opposite – disruption of classes, intimidation and victimisation, disrespect and often destruction of property.  A notion or approach of almost entitlement, even if the university management was willing to engage and was constantly open to assess ways and means to resolve these issues.  The drive for these protests was short-term gains, totally divorced from the long-term implications on the institution’s welfare.  This puts the university management under enormous pressure, sometimes feeling exposed and alone in ensuring that the institution remains sustainable – financially, as well as from an infrastructure and human resource perspective.

There is no doubt that the upcoming elections are used for political lobbying, tactical manoeuvring, and undermining to demonstrate political muscle – all playing out on our university campuses and to be managed by university vice-chancellors (VCs) and their executives.

Are universities not the pillars of knowledge in society, the providers of human capital and new knowledge to ‘lubricate’ our economy, the delivery of the next generation of professionals who will shape how our society, or a new South African citizenship should look like?  If this is the case, who are protecting our universities, who is standing with our VCs and university executives to ensure that our universities remain the beacon of hope for generations to come?  What is expected of VCs and university management in situations where there is a continual push for more, and if the response is not positive or immediate, protests, and in most instances violent and criminal behaviour. My personal view is not to securitise or militarise our campuses, but to resolve these issues through continuous engagement – but what if protests becomes violent and criminal?  What if disruptions challenge or threaten students, staff, infrastructure, and the academic project?  Student leaders seem to have forgotten the engagement with university leadership through a principle of ‘give and take’, always balancing short-term wins with the long-term sustainability and growth of the university.

Although universities often have their own internal disciplinary processes, these are slow, and the transgressors are often repeat offenders.  The sanctions are also in many cases restorative – which I believe it should, but to what end?

Help needed to ensure sustainability of universities 

We have seen how weak leadership, corrupt practices, and inadequate government funding have had a detrimental effect on the overall state of universities in the rest of the continent.  This has led to the outflow of excellent academics from the continent to elsewhere on the globe – a loss for the university and the continent!  Universities, although resilient, are also fragile as a system.  The protests associated with the #Rhodes and #FeesMustFall movements, together with the continued protests in 2019, run the risk of putting South African universities on a similar trajectory.  A fragile university system, when broken, will take decades to be restored.

Therefore, if universities are important institutions for society and the country, should there not be more concerted efforts from government and society to ensure that our universities remain strong and competitive? Although I do not offer a specific solution per se, should government, together with university leadership, staff, and students not be more vocal, thinking of a mechanism to curb and/or disallow immediate disruptions and the breakdown of infrastructure, and show visible support to university leadership in an effort to continue the academic project?  Our universities are performing extremely well against global counterparts, keeping in mind the current (and the past 10 years) South African economic growth and investment constraints with respect to infrastructure, research, and high-level scientific equipment – even a more critical argument to protect these national assets.

Academic project remains crucial

I am not for a moment belittling the issues raised by students and student leaderships – in fact, most, if not all of these issues, are legitimate.  I can understand the frustrations of the students – the slow pace of transformation, social integration, and often the lack of urgency in executing agreed decisions within the higher-education sector.  However, I am questioning the type of reaction or action exhibited by the students if, for similar legitimate reasons (through proper engagements), student demands cannot be completely met by university leaders.

In the final analysis, South Africa needs strong universities which are competitive – the country needs appropriate skills to enable and support the economy.  Also, universities need to listen to the student voice – deal with their concerns in a fair and socially-just manner; but as a sector with all its stakeholders, we need to ultimately respect the academic project and the infrastructure (physical and human) which support it.  We cannot afford party-political dynamics to ‘abuse’ the university campus in a way that can destroy the fibre of our higher-education system.  This will be catastrophic for South Africa, and I believe for the continent.

I call on government, voices in society, fellow students, student leadership, and staff to support university management openly, pro-actively and firmly, so that our universities remain places of intellectual engagement and discovery, places where different views are respected and heard, and by ‘jealously guarding’ the institutions as ‘country resources’, responding to all stakeholders’ concerns in a fair and just manner.

It is only then that universities ‘regain’ their rightful place in society, educating the next generation of scholars and professionals, advancing new knowledge, and purposefully disseminate and apply these to society – contributing to ‘lubricating the economy’ and to the betterment of the quality of life of our people!

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.
