The research efforts in the Department of Cardiothoracic Surgery in the Faculty of Health Sciences, UFS, have come a long way since the establishment of a homograft bank, animal research, and laboratory-based research on cardioplegia by Prof Hannes Meyer in the 1980s

Several world-class scientists and academics in the field of cardiovascular research will converge at the University of the Free State (UFS) on Thursday (5 May 2022) for a one-day hybrid conference to explore and celebrate the massive strides made in this critical field at the UFS Robert W M Frater Cardiovascular Research Centre.

The research efforts in the Department of Cardiothoracic Surgery in the Faculty of Health Sciences, UFS, have come a long way since the establishment of a homograft bank, animal research, and laboratory-based research on cardioplegia by Prof Hannes Meyer in the 1980s. Renewed interest in 2004 under the leadership of Prof Francis E Smit culminated in the establishment of the Robert W M Frater Cardiovascular Research Centre (the Frater Centre) in 2015. This was made possible through donor funding, especially by Dr Robert W M Frater MD PhD (honoris causa, UFS), a South Africa-born New York-based cardiothoracic surgeon, researcher and innovator as infrastructure and project support by the UFS.

The vision of the Frater Centre is to be a leading cardiovascular research institution in South Africa and sub-Saharan Africa. It provides an interdisciplinary training and research platform for scientists and clinicians from different backgrounds to develop as researchers and collaborators in cardiovascular and thoracic surgery and related domains. Activities are focused on the development of African solutions for African problems.

Three main divisions
The Frater Celebration day will highlight the achievements made thus far in a hybrid format in four sessions, which can be attended on a virtual platform or in person. The centre’s local and international collaborators will participate in the programme, and Dr Ronnie van der Merwe, the Group CEO of Mediclinic International, is the guest of honour.

The Frater Centre consists of three main divisions, all of which will form part of the focus of the conference programme in various forms during the day:

1) The Clinical Research Division addresses cardiovascular disease on a broad front, ranging from population and prevalence studies, healthcare solutions and clinical outcomes studies in a specific South African and African context.

2) The Research, Development and Commercialisation division is divided into Tissue Engineering and Cell Biology, Tissue Banking and Large Animal studies, and bioengineering to develop African solutions and technology within these domains.

3) The Simulation Programme provides an integrated interdisciplinary platform for the education and training of individuals and teams in cardiovascular, thoracic, anaesthetic, perfusion technology and related nursing fields in a state-of-the-art simulation unit. The research centre is developing a unique and leading programme and systems in this field. This endeavour is also developing IT models for training, evaluation and research.

The Frater Centre and 4IR
The Centre is firmly established in the fourth industrial revolution. It is new technology-driven, creating new IT platforms and boasts extensive interdisciplinary projects at the biomedical sector's local, national, and international levels.

It is essential to note that the extensive and successful collaboration within the Frater Centre not only exists on institutional level but also nationally and internationally. These collaborators assist, mentor, direct and contribute to the research activities.

From wheat protein to perfect pizza

Barend Wentzel, an alumnus of the University of the Free State’s Department of Plant Sciences, is passionate about plant breeding. 

He literally eats and lives wheat proteins. In 1989 he initiated a breeding programme on arum lilies. “This breeding programme is at an advanced stage,” he said. Besides reading, playing the piano and accordion, Barend, due to the nature of his research at the Agricultural Research Council, also experiments with different types of ciabatta recipes made from sour dough. “I usually make my own pizza on Saturday evenings,” he said.

He is working at the Agricultural Research Council – Small Grain (ARC-SG) at the Wheat Quality Laboratory where he established a Cereal Chemistry Laboratory.

Complexity of flour quality

He explains that the focus of his research is on wheat protein composition. “The research conducted for my PhD study explains the complexity of flour quality to a certain extent, and it further emphasises the influence of the environment and genetic composition on selected baking characteristics. 

“Wheat protein can be divided into different types of protein fractions. These protein fractions contribute differently to dough properties and baking quality and the expression is affected by different components in the environment, including locality, rainfall and temperature. 

“Protein content alone does, however, not explain the variation in baking quality parameters, such as mixing time, dough strength and extensibility, and loaf volume.

“Several methods can be applied to quantify the different protein fractions. I am using high-performance liquid-chromatography (HPLC). The procedure entails the separation of a wheat protein extract through a column with chromatographic packing material. The injected sample is pumped through the column (known as the stationary phase) with a solvent (known as the mobile phase). The specific procedure, size-exclusion high-performance liquid-chromatography (SE-HPLC), is also used by the university’s Department of Plant Breeding, as well as in several international Cereal Chemistry Laboratories,” said Barend.

Dough strength and to loaf volume
“One of the highlights from the study was the positive contribution of the albumin and globulin protein fractions to dough strength and to loaf volume. The findings were wheat cultivar specific and the growing environment influenced the expression. The contribution of these protein fractions was much larger than previously reported for South African wheat cultivars,” said Barend. 
“Previous reports indicated that these protein fractions had a non-specific contribution to the gluten network during dough formation. The findings from this PhD justify further research on albumins and globulin proteins.” 

The Cereal Chemistry Laboratory at ARC-SG is involved in postgraduate student training under Barend’s guidance. He serves as co-promoter for several MSc and PhD students. He is also a collaborator on an international project with the International Maize and Wheat Improvement Centre (CIMMYT) in Mexico. Barend is furthermore working on improving wheat quality for processing and health purposes as a member of the expert working group of the International Wheat Initiative.
