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.

Well-established root system important for sustainable production in semi-arid grasslands

The importance of a well-established root system for sustainable production in the semi-arid grasslands cannot be over-emphasised.

A study of Prof Hennie Snyman from the Department of Animal and Wildlife and Grassland Sciences at the University of the Free State is of the few studies in which soil-water instead of rainfall has been used to estimate above- and below-ground production of semi-arid grasslands. “In the past, plant ecological studies have concentrated largely on above-ground parts of the grassland ecosystem with less emphasis on root growth. This study is, therefore, one of the few done on root dynamics in drier areas,” said Prof Snyman.

The longevity of grass seeds in the soil seed bank is another aspect that is being investigated at present. This information could provide guidelines in grassland restoration.

“Understanding changes in the hydrological characteristics of grassland ecosystems with degradation is essential when making grassland management decisions in arid and semi-arid areas to ensure sustainable animal production. The impact of grassland degradation on productivity, root production, root/shoot ratios, and water-use efficiency has been quantified for the semi-arid grasslands over the last 35 years. Because of the great impact of sustainable management guidelines on land users, this study will be continuing for many years,” said Prof Snyman.

Water-use efficiency (WUE) is defined as the quantity of above- and/or below-ground plant produced over a given period of time per unit of water evapotranspired. Sampling is done from grassland artificially maintained in three different grassland conditions: good, moderate, and poor.

As much as 86, 89 and 94% of the roots for grasslands in good, moderate and poor conditions respectively occur at a depth of less than 300 mm. Root mass is strongly seasonal with the most active growth taking place during March and April. Root mass appears to be greater than above-ground production for these semi-arid areas, with an increase in roots in relation to above-ground production with grassland degradation. The mean monthly root/shoot ratios for grasslands in good, moderate, and poor conditions are 1.16, 1.11, and 1.37 respectively. Grassland degradation lowered above- and below-ground plant production significantly as well as water-use efficiency. The mean WUE (root production included) was 4.79, 3.54 and 2.47 kg ha -1 mm -1 for grasslands in good, moderate, and poor conditions respectively.

These water-use efficiency observations are among the few that also include root production in their calculations.
