My roller-coaster ride of mental health

My name is Thokozane Ngcongwane. I coordinate the UFSS1504 module in the Centre for Teaching and Learning (CTL). The journey of struggles and triumphs against mental illness has often peppered my life more than I thought. Having grown up in rural Free State, it was hard for my parents, as well as those around me, to believe that things such as mental illness exist – let alone their own son!

I grew up with attention-deficit / hyperactivity disorder (ADHD) and was admitted numerous times as the illness was misdiagnosed and untreated. This laid the foundation for a childhood filled with amazing feats of energetic activity, but also had the downside of being misunderstood, or ill-treated due to this illness. Before I knew about this illness, I believed that because of my height (I have been given the names ‘Napoleon’ and ‘Goliath’ by various people, throughout) and stature. I was a prime target for bullying.

Fast forward to university, and with the world as my oyster, I believed I would do well, graduate, and become the scientist I have always dreamed of becoming. Nothing could prepare me for the roller-coaster ride that, even to this day, has taught me highly valuable life lessons that I would never have received anywhere else. I started a degree in Chemistry (Extended) and was doing well in the first year. I was even fortunate enough to be selected for the F1 Leadership for Change exchange programme that took me to the USA. That was an incredible experience. Fast forward to my third year, and things took a turn for the worse.

By 2013, I started getting panic and anxiety attacks, the origin of which was quite unknown to me at the time. I thought that I was starting to go insane and this caused a huge drop in my academics, as well as distorting my overall view on life. I started refusing to see friends and family and even shunned myself from engaging in academics. This was the start of my battles and little prepared me for the fight ahead. I took a trip outside of my surroundings and became aware of how the people I avoided cared for me, and the result was that I overcame anxiety for that period. Family, friends, and lecturers were supportive and encouraged me to do my best amid this unknown period in my life. My academics improved and I became social again.

When I thought the worst was behind me, I was diagnosed with generalised anxiety disorder (GAD). I contacted Student Counselling and Development and received professional assistance. I started feeling better again and was on my way to graduating, albeit the journey was fraught with anxious moments. My graduation was delayed due to a credit shortfall, and this threw me in the deep end once again. This time, I dealt with it better by engaging myself in my passions – sports and the outdoors. I graduated in May 2016 and secured a temporary job as a Science teacher.

I returned home to the Qwaqwa Campus, where I became an intern in CTL. My troubles reached a boiling point in 2019, and I contacted Careways on recommendation of my head of department. It is now 2020, the year of global anxieties. I have learnt that institutions such as the South African Depression and Anxiety Group (SADAG) are available to help. Higher Health is also available to deal with issues around stigmatisation. In short, seek help and never abandon your support structures. Your mental health matters.

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.

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast 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.
