The executive committee of the University of the Free State (UFS) has today resumed the training of its undergraduate students in the School of Clinical Medicine at the Pelonomi Hospital in Bloemfontein with immediate effect.

The decision to suspend the training of undergraduate students at the hospital came after the attempted rape of a medical intern last week, as well as the robbery of a medical officer in the parking area of the hospital over the weekend.

This morning, discussions involving the university management, the Head of the Department of Health (DoH) in the Free State Province, the executive committee of the Pelonomi Hospital, and the South African Police Service (SAPS) took place regarding the security situation at the hospital. The DoH provided the university with a security project plan comprising immediate and medium-term interventions, and a commitment to execute the plan as a matter of urgency. The university’s executive management furthermore met with the management of the Faculty of Health Sciences and, based on a safety risk assessment, the university’s executive management agreed that undergraduate students could again fully access the clinical platform at Pelonomi Hospital.

Interventions in the security project plan include the installation of high-mast lights in the precinct of the hospital, reparation of the perimeter fence, security locks, and limiting access to the hospital and the hospital grounds after 20:00 until 06:00. A Venue Operation Centre (VOC) made up of SAPS, institutional security management, and the Community Policing Forum will also be established at the hospital.

“The main focus and concern for the executive management of the university is the safety of its students and staff. We are satisfied with the security plan and the overall interventions committed to by the DoH and will monitor the implementation of these interventions with the management of the Pelonomi Hospital and the DoH. The security interventions will alleviate the situation at the hospital in order for the university to continue sending its undergraduate students there for training,” said Prof Francis Petersen, UFS Rector and Vice-Chancellor, during a media briefing today.

Prof Petersen also met with undergraduate students in the Schools of Clinical Medicine, Nursing, and Allied Health Professions today to discuss the situation at the hospital. Trauma counselling is provided to undergraduate students and staff and those in need of counselling at the Pelonomi Hospital.

The DoH has furthermore extended its bus service between the clinical platforms in Bloemfontein to students in need of transport of the School of Clinical Medicine according to time slots as from the beginning of the second semester. This service will ultimately be extended to undergraduate students in the Schools of Nursing and Allied Health Professions. “We will also look into further transport solutions for the longer term for our students,” said Prof Petersen.

Undergraduate students from the university’s Schools of Clinical Medicine, Nursing, and Allied Health Professions are trained on the clinical platforms in Bloemfontein – these include the Pelonomi Hospital, Universitas Hospital, National Hospital, the Mangaung University Community Partnership Programme (MUCPP), and the Free State Psychiatric Complex.

Although these clinical training platforms are under the jurisdiction of the DoH in the Free State Province, they form a critical part of the training of undergraduate students in the university’s Faculty of Health Sciences. Staff on the joint establishment of the UFS and the DoH also work at hospitals on the clinical platforms.

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.
