Alison Botha
Over and above being a survivor, Alison Botha is an inspiration.
It was an ordinary December 1994 evening in Port Elizabeth. Alison Botha parked her car in front of her home. A man ambushed her at knife point. Minutes later, she was forced into the passenger seat and the perpetrator drove off, picking his friend up on their way to the coastal bushes of the city.
 
What was supposed to be an ordinary evening turned into a horrific experience which changed Botha’s life forever. She was raped, strangled, had her throat slit and her stomach cut open. Physicians called her survival a medical miracle. The true miracle though, is how she has chosen to deal with the experience. 

Botha overcame her fear of public speaking and has become an international motivational speaker who also authored a first-person account of her ordeal and recovery in 1998, titled I Have Life.

Aluta continua against gender-based violence

As part of our university’s advocacy against gender-based violence, the Human Resources’ Division for Organisational Development and Employee Wellness hosted Botha for a motivational talk on 5 June 2019 at the Bloemfontein Campus. In telling her story, Botha stated that she still receives healing.

While welcoming guests and the speaker, Prof Prakash Naidoo, Vice-Rector: Operations touched on Project Caring which is supported by the Rectorate. “We care for you and part of that caring agenda is gender-based violence. We encourage you to speak out about this issue, don’t remain silent, someone will listen,” he advised.

From victim to victor

Botha believes that if her story serves to help someone else avoid the same situation or perhaps even survive a similar trauma, then she has served her purpose. “I now believe that the evil is far outweighed by all the good that has come out of my choice to share my story,” she said.

Much of the reason behind her strength lies in what she terms her own ABC principle which speaks to attitude, belief and choice. “We are not always going to be in control of everything that happens to us. But we always control how we respond,” said Botha. 

The story of Botha’s survival, recovery and victory proves that the human spirit cannot be crushed. There is indeed life after a near-death tragedy.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
