WomenofKovsies Kesa praises the most important woman in her life
Kesa Molotsane, top Kovsies athlete says much of her success is thanks to the amazing backing of her mother Shani.

Most of Kesa Molotsane’s achievements on the athletic track and road can be attributed to the tireless support of her mother, Kesa says.  

“It might sound like a cliché, but my mother has taught me so much and I have learnt enough from her to survive anything. She has played the biggest role in my career and made it a priority in her life even before it (her athletics career) blossomed. 

‘My mother invested in me’

“My mother Shani has invested so much. She was present at the start and to this day she is still there for me,” Kesa says about the most important woman in her life.

Molotsane, who is doing her BA honours at the University of the Free State, has had a good 12 months behind her. She is the Spar Grand Prix 10km champion from last year, is the national student champion in the 5 000m and 10 000m and was the best South African performer at the Confederation of African Athletics African Cross Country Championships.

‘Improvement and growth motivates me’

She says improvement and growth motivates her big time. “It’s a way of weighing my efforts and hard work. I am inspired by a lot of things, depending on what situation I am in and the inspiration I’m looking for. I believe in and value inspiration in abundance.”

According to her, representing her country at the World Cross Country Championships in Uganda in March 2017 was the biggest accomplishment of her career. “It was my first time at world championships and I was the first South African to cross the finish line. I want to leave my legacy for years to come and want to touch lives using my God-given talent and gift.”

Link between champagne bubbles and the UFS?

What is the link between the bubbles in champagne and breakthrough research being done at the Mayo Clinic in America? Nano research being done at our university.

Prof. Lodewyk Kock of Biotechnology says a human being consists of millions of minute cells that are invisible to the eye. The nano technology team at the UFS have developed a technique that allows researchers to look into such a cell, as well as other microorganisms. In this way, they can get an idea of what the cell’s “insides” look like.

The UFS team – consisting of Profs. Kock, Hendrik Swart (Physics), Pieter van Wyk (Centre for Microscopy), as well as Dr Chantel Swart (Biotechnology), Dr Carlien Pohl (Biotechnology) and Liza Coetsee (Physics) – were amazed to see that the inside of cells consist of a maze of small tunnels or blisters. Each tunnel is about 100 and more nanometres in diameter – about one ten thousandth of a millimetre – that weaves through the cells in a maze.

It was also found that these tunnels are the “lungs” of the cells. Academics doing research on yeast have had to sit up and take notice of the research being done at the UFS – to the extent that these “lungs” will appear on the front page of the highly acclaimed FEMS Yeast Research for all of 2013.

The Mayo Clinic, in particular, now wants to work with the UFS to study cancer cells in more detail in order to fight this disease, says Prof. Kock. The National Cancer Institute of America has also shown interest. This new nano technology for biology can assist in the study and development of nano medicine that can be used in the treatment of cancer and other life threatening diseases. Nano medicine uses nano metal participles that are up to one billionth of a metre in size.

Prof. Kock says laboratory tests indicate that nano medicine can improve the efficacy of anti-cancer medicine, which makes the treatment less toxic. “According to the Mayo Clinic team, nano particles are considered as a gold cartridge which is being fired directly at a cancer tumour. This is compared to fine shot that spreads through the body and also attacks healthy cells.”

“This accuracy implies that the chemotherapy dose can be lowered with fewer side effects. The Mayo Clinic found that one-tenth of the normal dosage is more effective against pancreas cancer in this way than the full dosage with a linkage to nano particles. According to the clinic, this nano medicine could also delay the spread of cancer,” says Prof. Kock.

The nano particles are used as messengers that convey anti-cancer treatment to cancer cells, where it then selectively kills the cancer cells. The transport and transfer of these medicines with regard to gold nano particles can be traced with the UFS’s nano technology to collect more information, especially where it works on the cell.

“With the new nano technology of the UFS, it is possible to do nano surgery on the cells by slicing the cells in nanometre thin slices while the working of the nano medicine is studied. In this way, it can be established if the nano medicine penetrates the cells or if it is only associated with the tiny tunnels,” says Prof. Kock.

And in champagne the small “lungs” are responsible for the bubbles. The same applies to beer and with this discovery a whole new reach field opens for scientists.
