Melissa de Aveiro inspires UFS with journey about rising from the ashes

Singer, writer, and motivational speaker, Melissa de Aveiro, says: “One can only rise from the ashes when the fire starts again, and the beauty of it all is that the ashes is stuck to your clothes. As you move on, you build off it as it falls from your clothes.”

She said: “When the fire starts in you, nothing is going to stop it.”

This she said at the Division of Organisational Development and Employee Well-being’s Rising from the Ashes event held at the Centenary Complex on the Bloemfontein Campus. Melissa’s story is about never giving up and “never backing down – even when people throw you with rocks, use the rocks to build a new road”.

Melissa said: “Many people unfortunately do not rise from the ashes because there is no support from friends, people. You can never do it alone as the journey through the ashes is lonely.”

Melissa believes to get through the ashes, one has to go back and “remind yourself of when it was good in your life, remind yourself about the positive things – even though things might not be great now”.

Known as the 'Weskus Dutchess', and growing up in Vredendal, Western Cape, Melissa’s tough life, sexual abuse, drug abuse, homelessness, and the death of her son never stopped her from dreaming. All the setbacks planted in her a “passion for a guitar and people, a birth of a new season, a desire to change the world”.

To rise from the ashes, Melissa said, “You need to go back to the place where you were hurting, confront the demons, the people that abused you, maybe forgive them and remove the chains you are tied with.”

Susan van Jaarsveld, Senior Director: Human Resources at the University of the Free State, believes that hosting wellness events is a way for the UFS to show that “employees are the most valuable asset of the university and need to be looked after”.

Susan said: “Staff need to know that it is okay not to be okay. However, the UFS has systems to look after your well-being. People need to know that they are not alone, they can make use of the Department of Human Resources’ Careways Employee Wellness Programme.”

Susan believes it was important to host the event, as “staff need face-to-face interaction for their well-being, it helps people to know they are not alone”.

Melissa, the author of the book Weskus Wonderwerk, believes in being unstoppable. She said: “To rise from the trenches, always think positive about yourself, you must exist. You cannot give up; your worth cannot be determined by an individual.”

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.
