Mission: Possible

Dr Samantha Potgieter, Senior Lecturer in the Department of Internal Medicine and Dr Nicholas Pearce, Senior Lecturer in the Department of Surgery comment on their team members’ commitment and determination during the pandemic.

On the forefront of the battle against the COVID-19 pandemic, two UFS doctors are leading a team of inspired healthcare workers in a superhuman effort to make a positive difference.

With the pandemic in its second year and the recurring challenges of new waves and strains consistently in the news, one would expect the doctors to be tired. However, quite the opposite is true. Upon entering the office where Dr Samantha Potgieter, Senior Lecturer in the Department of Internal Medicine and Dr Nicholas Pearce, Senior Lecturer in the Department of Surgery are in a meeting with colleagues, the debate is vibrant; an energetic sense of mission.

Miraculously succeeded

My brief is to collect stories and experiences they’ve had over the past 18 months at the Tumelo ward for general and high-care patients, where the team has miraculously succeeded in not running out of oxygen or ventilators, despite handling high volumes of patients from the Free State and Northern Cape. “We saw those pictures of piled-up bodies in Italy. We were committed to avoiding that at all costs. And we did.”

Success stories? First mentioned are their team members’ commitment and determination. The team had to stand in when families could not support dying patients. “They did not die alone. Our team was there.”

“Really sad and frustrating are the deaths that could have been prevented. Unvaccinated patients. They arrive ill, wanting to know if they can get it. Too late...” – Dr Nicholas Pearce

Then came hope

Sad stories? The past year has had its share of sad stories. “Someone comes in during the morning, needs oxygen, in the afternoon they are in ICU, then ventilator – and then they die. We’ve never faced anything like this before.”

Then came hope. Vaccines. Dr Pearce is in charge of the vaccination site at Universitas Hospital. “Really sad and frustrating are the deaths that could have been prevented. Unvaccinated patients. They arrive ill, wanting to know if they can get it. Too late ...” He opens his cell phone – shares the stats. “We can handle 2 000 vaccinations a day. At the moment about 250 comes in.” He shakes his head.

“We can beat this virus, but we need to stand together ...”

UFS boasts with most advanced chemical research apparatus in Africa

The University of the Free State’s (UFS) Department of Chemistry now boasts with some of the most advanced chemical research apparatus in Africa after the latest addition, a nuclear magnetic resonance (NMR) spectrometer, was inaugurated today by the Rector and Vice-Chancellor, Prof Frederick Fourie. The NMR is used to analyse molecular structures.

Last month the Department of Chemistry celebrated the installation of the most advanced single crystal X-ray diffractometer in Africa. The diffractometer provides an indispensable technique to investigate among others the solid state of compounds for medicinal application.

“Three years ago the UFS executive management realised that, if we want to build a university of excellence, we should invest in research. We started to think strategically about chemistry and decided to bring the apparatus at the Department of Chemistry on a more competitive standard. Strategic partnerships were therefore secured with companies like Sasol,” said Prof Fourie during the inauguration ceremony.

“The installation of the NMR symbolises the ability of the UFS to turn academic areas around. I hope that this is the beginning of a decade of excellence for chemistry at the UFS,” said Prof Fourie.

”The catalogue value of the Bruker 600 MHz NMR is approximately R11 million. With such an advanced apparatus we are now able to train much more post-graduate students,“ said Prof Jannie Swarts, head of the Division Physical Chemistry at the UFS.

”The NMR is the flagship apparatus of the UFS Department of Chemistry that enables chemists to look at compounds more easily at a molecular level. Research in chemistry is critically dependent on NMR, which is a technique that can determine the composition of reactants and products in complicated chemical reactions, with direct application is most focus areas in chemistry,“ said Prof Swarts.

”Parts of the spectrometer consists of non-commercial items that were specifically designed for the UFS Department of Chemistry to allow the study of unique interactions in e.g. rhodium and platinum compounds,” said Prof Swarts.

According to Prof Swarts the NMR enables chemists to conduct investigations on the following:

To evaluate for example the complex behaviour of DNA in proteins as well as the analysis of illegal drugs sometimes used by athletes.
It provides an indispensable technique to investigate compounds for medicinal application for example in breast, prostate and related bone cancer identification and therapy, which are currently synthesised in the Department of Chemistry.
It can also be applied to the area of homogeneous catalysis where new and improved compounds for industrial application are synthesized and characterised, whereby Sasol and even the international petrochemical industry could benefit. This analytical capacity is highly rated, especially in the current climate of increased oil prices.
The NMR can detect and identify small concentrations of impurities in feed streams in the petrochemical industry, e.g. at Sasol and also the international petrochemical industry. These minute amounts of impurities can result in metal catalyst deactivation or decomposition and can cause million of rands worth in product losses.
It is indispensable for studying the complexity of samples that is non-crystalline. These materials represent the vast majority of chemical compounds such as solvents, gasoline, cooking oil, cleaning agents and colorants as examples.

According to Prof Swarts the general medical technique of MRI (magnetic resonance imaging) in use at larger hospitals, is based on NMR technology.

”The NMR apparatus enabled the Department of Chemistry to characterise complex molecules that were synthesised for the multi-national company, FARMOFS-PAREXEL, and to negotiate research agreements with overseas universities,” said Prof Swarts.
