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.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
