Research possibilities of zebrafish exposed
Leading global genetics laboratories are replacing research on human and animal populations with zebrafish, says Prof Paul Grobler, Head of the UFS Department of Genetics.

The UFS Department of Genetics is on par with current research trends in terms of their zebrafish project. About a year has passed since they seriously started focusing on the potential of this tiny four-centimetre-long fish, and the possibilities are hugely exciting.

Looks are deceiving

Leading global genetics laboratories are replacing research on human and animal populations with zebrafish due to several fascinating reasons, of which the most profound is probably that the zebrafish share large portions of its genome with mammals. For genetics researchers this may make a lot of sense, but most people battle to see any resemblance between a six-foot-tall rugby player or 600 kg buffalo and a small, nearly transparent fish. It is in the detail, the researchers say.

Fast, effective, and visible

“The complete genome sequence of the zebrafish is known, and as much as 84% of genes known to be associated with human disease have zebrafish counterparts,” explains Head of Department, Prof Paul Grobler. Another advantage is the fast breeding rate and short generation time, and the fact that some research is ethically more justifiable when done on fish larvae rather than on adult mammals. The fact that zebrafish embryos are virtually transparent, also allow researchers to examine the development of internal structures without effort. Every blood vessel in a living zebrafish embryo is visible under a low-power microscope.

Multidisciplinary

Zebrafish provide research potential for many different study fields besides that of Prof Grobler and his team, Sue Rica Schneider and Dr Willem Coetzer. In the near future, they aim to have undergraduate students use zebrafish as a research model to develop a real sense of research and laboratory work. The Department of Chemistry are also initiating research on zebrafish housed in the Department of Genetics.

First M degree in Sport Medicine commences at the UFS   
 

The classes of the first group of nine students registered for the M degree in Sport Medicine at the University of the Free State (UFS) commenced at the School of Medicine this week.

This is the first degree of its kind presented by the UFS.  Only two other universities in South Africa are presenting the course, namely the University of Cape Town and the University of Pretoria.

“It is an important new subject field for medicine in South Africa and is aimed at medical doctors,” said Dr Louis Holtzhausen, Programme Director of Sport Medicine in the School of Medicine and head of the UFS Sport and Exercise Medicine Clinic.

The course focuses on the wellness and healthy lifestyle of patients and also intercepts the growing need for a specialized medical service for sportsmen,” said Dr Holtzhausen.

Athletes’ needs for specialised medical care have increased dramatically during the past ten years.  “The primary health care practitioner has already surrendered a great deal of the athletics community to disciplines such as physiotherapy, bio kinetics, homeopathy, chirology and other alternative disciplines because of a lack to provide for these practitioners,” said Dr Holtzhausen.

“The course is especially in demand with general practitioners because they want to deliver a more specialized service to patients.  With this course a student can call him/herself a sport doctor and will then not only be able to present patients with scientifically funded exercise, food supplements and advice on their lifestyle, but will also be able to help with the rehabilitation of patients with chronic illnesses,” said Dr Holtzhausen.

“The greatest medical care expense in South African stems from lifestyle bound illnesses such as depression, strokes and obesesiveness.  The M degree in Sports Medicine at the UFS will intercept some of these problems,” said Dr Holtzhausen.

According to Dr Holtzhausen the duration of the degree is three years and it comprises of three legs.  In the first leg, attention is given to an athlete’s performance and how it can be improved with the correct methods and supplements.  In the second leg attention is given to the wellness of patients and the reversibility of the risk of illness and the exercise rehabilitation of chronic illnesses such as diabetes and hart problems to assist patients to exercise in a scientific way in order for them to start living optimally again.  In the third leg attention is given to a healthier lifestyle as a precautionary measure. 

The course also includes a lecture part (four attendance sessions of seven days each) and a thesis.  

“The new course is important for the UFS as the whole tendency in medicine is to move into a direction of a more affordable precaution.  There is no other qualification or programme with as much detail as this course,” he said.
