Dr Michael Pienaar, Senior Lecturer and specialist in the UFS Department of Paediatrics and Child Health, is a finalist in two categories of this year’s NSTF-South32 Awards. Dr Edward C Netherlands, Senior Lecturer in the UFS Department of Zoology and Entomology, is also in the running for his first NSTF-South32 Award.

Dr Michael Pienaar, Senior Lecturer and Specialist in the University of the Free State (UFS) Department of Paediatrics and Child Health, is a finalist in two categories of the 2023 NSTF-South32 Awards, popularly known as the ‘Science Oscars’ of South Africa.

Dr Pienaar, who has been working in paediatric critical care since 2019 and sees the care of critically ill children as his mission and calling in life, has been named a finalist in the TW Kambule-NSTF Award: Emerging Researcher and the NSTF-SAMRC Clinician-Scientist Award categories.

Another UFS staff member, Dr Edward C Netherlands, Senior Lecturer in the Department of Zoology and Entomology, is also a finalist in the TW Kambule-NSTF Award: Emerging Researcher category.

The NSTF-SAMRC Clinician-Scientist Award, sponsored by the South African Medical Research Council (SAMRC), is a new award for an outstanding contribution by a clinician-scientist, with a focus on work to enhance life and improve community health. This new category is modelled on the Emerging Researcher category.

‘Validating to have research recognised’

Dr Pienaar says it is humbling to be considered for these awards alongside formidable, accomplished, and innovative clinicians and scientists. “This is all somewhat surreal, as I was not anticipating being shortlisted as a finalist. It is validating to have had my research, which I am committed to, recognised on this platform. I am very grateful to the School of Clinical Medicine and the Faculty of Health Sciences and University of the Free State for nominating me for these awards.”

He was nominated by Dr Claire Armour Barrett, Clinical Research Director and Specialist Physician in the UFS School of Clinical Medicine.

Dr Pienaar says his current research focusses on applied machine learning in paediatric critical care. He has been working on the development of machine learning models that can be used in clinical practice to improve patient care.

“The work leading to these nominations focused on triage and identification of critically ill children in South Africa. Currently, I am working towards machine learning models implemented in point-of-care ultrasonography and mechanical ventilation.

“I am pleased just to be shortlisted for these awards. I think this provides important visibility for my work, which I feel has major long-term implications for clinical practice. I am also very happy to represent the research work being done in the Faculty of Health Sciences and the UFS on this platform.”

On what it will mean to win a ‘Science Oscar’, Dr Pienaar says, “While this would advance my career, I am very aware that all the candidates would be worthy winners. As it is, the opportunity to be a scholar is reward unto itself, and I am very privileged to be able to do the research I do. As ever, I am very grateful to the University and the Faculty of Health Sciences as well as the National Research Foundation for supporting my work.”

‘Honour and privilege’

Dr Netherlands, who was nominated by Prof Corli Witthuhn, former UFS Vice-Rector for Research and Internationalisation, says, “It is a great honour and privilege to represent the UFS.”

His work as a parasitologist and herpetologist involves specialised research in the study of blood parasites. His current research focuses on the diversity, evolution, and ecological implications of blood parasites in herpetofauna (reptiles and amphibians of a particular region).

“Being shortlisted as a finalist for this award will be a humbling achievement in my career, that may lead to new opportunities and new collaborations,” Dr Netherlands says. “Furthermore, being shortlisted provides a sense of validation and affirmation for the effort that has gone into conducting my research.”

The announcement of the winners will take place at the NSTF-South32 Awards Gala Event on 13 July 2023.

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.
