Michelle Middle, CMO of Farmovs, looks forward to expanding their operations after the UFS acquired 100% shareholding in 2018.

In medical research, there are NO shortcuts.

The journey of a new medicine from lab to pharmacy shelf takes on average at least 10 years.

Michelle Middle’s journey from young medical graduate starting her first job at FARMOVS to becoming the company’s Chief Medical Officer, was more than twice that long. It was a journey that systematically and adequately equipped her to now Co-captain this flagship enterprise through its biggest challenge yet.

Michelle remembers how Farmovs started in 1974 as a research centre in the Department of Pharmacology. After graduating as medical doctor, she joined Farmovs in 1993, shortly before they moved to their current extensive facilities just south of the Sasol Library.

In 2000, international Clinical Research Organization (CRO) giant Parexel acquired a 70% shareholding, and the name changed to Farmovs-Parexel.

“Parexel really invested a lot in infrastructure and technology, bringing facilities here on par with the best in the world,” says Michelle.

Her own journey in medical research took her to George and later to the US and UK, where she held various international executive leadership positions in international companies.

When the UFS acquired a 100% shareholding in Farmovs earlier this year, she came full circle, as she returned to Bloemfontein to spearhead the expansion of patient studies in collaboration with the Faculty of Health Sciences.

“The opportunities we have here are really enormous,” says an excited Michelle.

“We are the only university in the country with this kind of infrastructure. Apart from our state-of-the-art bioanalytical lab, we also have facilities to accommodate close to 100 research participants. We now have 45 years’ experience in advanced medical research, plus established international clients. We can provide pharmaceutical companies with basically everything they need to develop new medicines.”

Another exciting development is that they are expanding their clinical-trial patient population next year from healthy individuals to people suffering from a host of chronic conditions.

“While they are part of our clinical trials, patients gain valuable insight in their own conditions. We also sometimes pick up underlying medical issues they were not even aware of,” says Michelle.

The 150 Farmovs staff members range from doctors and nurses, to technologists, medical writers, and managers. While not technically part of the university staff, they form a valued part of the Bloemfontein Campus community.

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.
