Karla takes netball world by storm
Karla Pretorius, vice-captain of the Protea netball team, has become a leading player in world netball.

The University of the Free State (UFS) has produced a number of exceptional netball players over the years, but none quite on the level of Karla Pretorius, who is widely considered as probably the very best in her position.

 

A whole new level


Pretorius, who is completing her postgraduate studies in Dietetics, was already deemed one of the best when she left for Australia at the end of 2016; however, she has since risen to a whole new level. The Protea vice-captain plays for the Sunshine Coast Lightning in Australia’s Suncorp Super Netball league, the world’s leading competition. She is scheduled to return there again next year. Karla comfortably leads the stats with a total of 50 intercepts and was named in the Team of the Tournament.

 

According to the former Australian coach, Norma Plummer, who is now at the helm of the Proteas, “Karla currently has to be one of the best, if not the best, goal defenders playing at this moment in time.”

 

Karla’s ability to come through with speed-anticipating interceptions is something that is so exciting to watch. She is very versatile and can switch from one-on-one to split circle or other defensive styles, explained Norma. She says Karla is light in stature but physically very strong.

 

Keep on improving

 

According to Pretorius, who played for the Kovsies between 2009 and 2015, playing in an environment where every possible aspect gets attention – with emphasis on detail – has benefited her immensely. “Everything is done so professionally to eventually push you to become the best possible player.” Karla explained that she experiences challenges in many fields of her life but has the chance to play with and against the best players with different skills, which helps her to keep on improving and bettering her craft.

Champagne and cancer have more in common than you might think

No, a glass of champagne will not cure cancer....

…But they have more in common than you might think.

Researchers from the Departments of Microbial Biochemical and Food Biotechnology, Physics and the Centre for Microscopy at the University of the Free State in South Africa were recently exploring the properties of yeast cells in wine and food to find out more of how yeast was able to manufacture the gas that caused bread to rise, champagne to fizz and traditional beer to foam. And the discovery they made is a breakthrough that may have enormous implications for the treatment of diseases in humans.

The team discovered that they could slice open cells with argon gas particles, and look inside. They were surprised to find a maze of tiny passages like gas chambers that allowed each cell to ‘breathe.’ It is this tiny set of ‘lungs’ that puts the bubbles in your bubbly and the bounce in your bread.

But it was the technique that the researchers used to open up the cells that caught the attention of the scientists at the Mayo Clinic (Tumor Angiogenesis and Vascular Biology Research Centre) in the US.

Using this technology, they ultimately aim to peer inside cells taken from a cancer patient to see how treatment was progressing. In this way they would be able to assist the Mayo team to target treatments more effectively, reduce dosages in order to make treatment gentler on the patient, and have an accurate view of how the cancer was being eliminated.

“Yes, we are working with the Mayo Clinic,” said Profes Lodewyk Kock from the Microbial, Biochemical and Food Biotechnology Department at the UFS.

“This technique we developed has enormous potential for cell research, whether it is for cancer treatment or any other investigation into the working of cells. Through nanotechnology, and our own invention called Auger-architectomics, we are able to see where no-one has been able to see before.”

The team of Prof Kock including Dr Chantel Swart, Kumisho Dithebe, Prof Hendrik Swart (Physics, UFS) and Prof Pieter van Wyk (Centre for Microscopy, UFS) unlocked the ‘missing link’ that explains the existence of bubbles inside yeasts, and incidentally have created a possible technique for tracking drug and chemotherapy treatment in human cells.

Their work has been published recently in FEMS Yeast Research, the leading international journal on yeast research. In addition, their discovery has been selected for display on the cover page of all 2013 issues of this journal.

One can most certainly raise a glass of champagne to celebrate that!
