Tobias van den Bergh
Tobias van den Bergh, President of the Southern African Association for Counselling and Development in Higher Education (SAACHDE)

Tobias van den Bergh, Counselling Psychologist at the University of the Free State, has been appointed as the President of the Southern African Association for Counselling and Development in Higher Education (SAACDHE).  The appointment became official at the annual SAACDHE conference, which took place in Pretoria from 12 to 14 September 2022. As such, van den Bergh perceives this appointment as an opportunity: “To be part of a creative process that tackles the challenges faced in higher education and knowing the difficulty that students and my colleagues across the country are struggling with, accepting this appointment felt right.”

The role of SAACDHE

“The organisation represents members of several higher education counselling and career development centres from the SADC region. The organisation’s mission is to promote, guide, and advance best practices in centres at institutions of higher education,” explained Van den Bergh. Through this representation and assistance, members are able to provide quality support to the students they serve. SAACDHE members include mental health professionals, social workers, HIV/AIDS counsellors, researchers, and career development specialists from more than 15 higher education institutions in South Africa and Botswana. Furthermore, Van den Bergh asserts that, “SAACDHE represents its members through lobbying for increased institutional support, the promotion of scholarly, ethical, and best practices, and the training and development of professionals.”

Van den Bergh as President of the organisation

 As the newly elected President of the organisation, there are several challenges that Van den Bergh believes require the immediate attention of SAACDHE.  For instance, he maintains that student populations and the mental health challenges they face have grown at a substantial rate over the past few decades. However, the staff capacity in counselling and career development centres has not increased commensurately. As such, the challenge in this regard is that the need for mental health interventions continues to grow, but the capacity is not sufficient to deal with those challenges and to fill the gap in public mental health services. To address this challenge, he indicates that “the organisation is striving to innovate counselling centres, and to find ways to work smarter and be preventative where possible”.

In addition, Van den Bergh is adamant about ensuring that the organisation continues to be innovative in the way mental health services are provided to students, and to create practices that are culturally and contextually relevant. However, his long-term vision for the organisation is, “to continue serving as a training, development, and practice-based organisation, so that we can equip members with support and knowledge that will help them to continue helping students in a smarter and better way”.

UFS study on cell development in top international science journal
2008-09-16

A study from the University of the Free State (UFS) on how the change in the packaging of DNA with cell development influenced the expression of genes, will be published in this week’s early edition of the prestigious international, peer-reviewed science journal, the Proceeding of the National Academy of Sciences of the USA (PNAS).

The PNAS journal has an impact factor of 10, which means that studies published in the journal are, on average, referred to by ten other scientific studies in a two year period. The South African Journal of Science, by comparison, has an impact factor of 0.7.

The UFS study, funded by the Wellcome Trust and the National Research Foundation (NRF), looked at how the change in the packaging of DNA with cell development influenced the expression of genes. It is very relevant to research on stem cells, an area of medicine that studies the possible use of undifferentiated cells to replace damaged tissue.

Prof. Hugh Patterton, of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, who led the study, said: "We are extremely proud of this study. It was conceived in South Africa, it was performed in South Africa, the data were analysed in South Africa, and it was published from South Africa."

When a gene is expressed, the information encoded in the gene is used to manufacture a specific protein. In eukaryotes, which include humans, there is approximately 1m of DNA, containing the genes, in every cell. This length of DNA has to fit into a cell nucleus with a diameter of only about 10 micrometer. In order to fit the DNA into such a small volume, eukaryotic cells wrap their DNA onto successive protein balls, termed nucleosomes. Strings of nucleosomes, resembling a bead of pearls, is folded into a helix to form a chromatin fiber. The study from the UFS investigated how the binding of a specific protein, termed a linker histone, that binds to the length of DNA between nucleosomes, influenced the formation of the chromatin fiber and also the activity of genes.

"We found that the linker histone bound to chromatin in yeast, which we use as a model eukaryote, under conditions where virtually all the genes in the organism were inactive. It was widely believed that the binding of the linker histone caused the inactivation of genes. We studied the relationship between the amount of linker histone bound in the vicinity of each gene and the expression of that gene for all the genes in yeast, using genomic techniques. We made the surprising discovery that even through the linker histone preferentially bound to genes under conditions where the genes were shut off, this inactivation of genes was not caused by the binding of the linker histone and folding of the chromatin,” said Prof. Patterton.

He said: “Instead our data strongly suggested that the observed anti-correlation was due to the movement of enzymes along the DNA molecule, involved in processing the information in genes for the eventual manufacture of proteins. This movement of enzymes displaced the linker histones from the DNA. This finding now requires a rethink on aspects of how packaging of DNA influences gene activity."

Prof. Patterton said that his research group, using the Facility for Genomics and Proteomics as well as the Bioinformatics Node at the UFS, was currently busy with follow-up studies to understand how other proteins in nucleosomes affected the activities of genes, as well as with projects to understand how chemicals found in red wine and in green tea extended lifespan. "We are certainly having a marvelous time trying to understand the fundamental mechanisms of life, and the UFS is an exciting place to be if one was interested in studying life at the level of molecules," he said.
