As part of the Faculty of Health Sciences’ Awareness Initiative for Mental Health (FoHS AIM High) to raise awareness regarding mental health and well-being among students and staff, the faculty held a photo competition for its students and staff members. 

The competition with the theme, Things my Gogo taught me, received 70 entries and according to the Programme Director in the School of Clinical medicine, Dr Lynette Van der Merwe, the project was aimed at encouraging students and staff members to show creativity and passion by sharing photos with a reflection on the theme.
For the year 2021, the mental health awareness competition had six (6) winners for both student and staff. The photo competition was judged by Prof Willem Kruger, head of the Department of Community Health and an award-winning photographer.

An opportunity to celebrate grandmothers

Mrs Mary-Ann Naudé, author, and Mrs Madeleen Eygelaar, photographer, were the joint winners of the first prize in the staff category. The competition gave Naude, an Assistant Officer at the Clinical Skills Unit for the School of Health and Rehabilitation Sciences, an opportunity to celebrate the life of her grandmother Mary, whose value, despite her generous soul, was unfortunately not always valued while she was alive.

“The competition made me think of the influences on my life of strong women like my two oumas and my mother. I realised that I am who I am today because of their hard work and their examples. I am overwhelmed with gratitude. I feel honoured that our entry was chosen above the many, many excellent other entries,” says Naudé.

The joint winner of the staff category, Eygelaar, a physiotherapy junior lecturer at the Department of Physiotherapy, says she grew up without a mother, losing hers at a young age, and learnt about life, nature, love and art from her grandmother. 

“I wished to celebrate her, capturing the influence she had over my life. She is still the light in my life and the warmth in my soul, as I am fortunate that she is still alive. However, she lives far away. I was happy to join with Mary-Ann in sharing our love of our grandmothers in order to symbolically capture those expressions of love.

joint winners of the first prize in the staff category of the Faculty of Health Sciences’
photo competition with the theme, Things my Gogo taught me.

“The photo competition made me realise what a privilege it is to have a grandmother in your life, who share love and wisdom with you in a gentle and kind manner. Winning the competition, I was surprised, as I did not expect others to feel the same emotions I felt when taking the photos. It is a blessing to touch others with a picture that means so much to me personally. In that regard, I am very thankful. I was impressed with so many other beautiful photos that told the story of the love of their grandmothers, so I was humbled to receive acknowledgement for mine.”


Competition was a way of expressing her journey

The student category winner, Shezree Tiel, who is a third-year medical student, said the competition was a way of expressing her journey in the medical field. She saw an opportunity to tell her story on how she dealt with mental health problems during her studies through a photo. 

Shezree had lost hope in her studies and her mental health was a serious challenge. She wanted to share her story by encouraging other students not to lose hope and the competition gave her motivation to speak out about how she feels and deals with mental-health related issues. 

Given the hardships during COVID-19, Shezree felt happy and courageous to win the prize. “It will help me to encourage others to share how they feel about mental health and well-being,” she said.

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.
