Dr Mariana Erasmus (Vice Director, CMBG) demonstrates some of the equipment in the newly established, state-of-the-art laboratories at the Centre for Mineral Biogeochemistry.

The University of the Free State (UFS) recently hosted a landmark event-the national launch of the South African Biogeochemistry Research Infrastructure Platform (BIOGRIP) - in the Centenary Complex on its Bloemfontein Campus. This significant occasion marked the establishment of the Centre for Mineral Biogeochemistry at the UFS and underscored South Africa’s growing commitment to biogeochemistry research.

Prof Anthea Rhoda welcomed the distinguished gathering of scientists, students, industry leaders, and stakeholders, highlighting the launch as a collaborative milestone in South Africa's scientific journey. In her address, Prof Rhoda emphasised the importance of the interdisciplinary nature of biogeochemistry, where biology, geology, and chemistry converge to offer insights into critical issues such as climate change, water quality, and soil health. She remarked on the necessity of collaboration, explaining that BIOGRIP’s platform, built on shared resources and expertise, exemplifies the power of uniting across institutional boundaries to accelerate impactful discoveries.

The programme featured insightful scientific talks by leading experts, each focusing on how biogeochemistry addresses key environmental issues such as sustainability and resource management. These presentations reinforced BIOGRIP’s commitment to advancing knowledge that can influence policy and improve practices.

Attendees were also given guided tours of the state-of-the-art laboratories in the Centre for Mineral Biogeochemistry, which provided a behind-the-scenes look at the advanced tools and methods employed in studying interactions between minerals, biology, and the environment. For many, this was a highlight, as they observed firsthand how biogeochemical research is conducted and contributes to soil health, pollution control, and environmental conservation.

The launch provided ample networking opportunities, fostering connections among academics, government representatives, industry professionals, and environmental organisations. Over a catered lunch, participants engaged in vibrant discussions about potential collaborations and the role of biogeochemistry in addressing South Africa’s environmental challenges.

The BIOGRIP national launch stands as a milestone event, not only for the UFS, but for the broader South African scientific community. With the establishment of this research platform, South Africa is well-positioned to tackle pressing environmental issues through innovative research and cross-sector collaboration. The event left attendees inspired and motivated, setting an optimistic tone for the future of biogeochemistry research in the region.

Three heart-valve studies which have been developed at the Robert WM Frater Cardiovascular Research Centre at the School of Medicine at the University of the Free State (UFS) were recently presented in Monte Carlo at the conference of the prestigious global Heart Valve Society (HVS).

These studies are all headed by Prof Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS, and Manager of the Robert WM Frater Cardiovascular Research Centre.
Prof Smit says the HVS is a combination of the former heart-valve societies of Europe and the US. “Studies on heart-valve disease, heart-valve-related products and operations, as well as the design and development of new valves were presented. There are both clinical and development divisions.

He says the study in which the hemodynamics of their redesigned mechanical poppet valve was compared to a commercial bi-leaflet mechanical heart valve, was named as the best poster presentation in the experimental valve development and numerical flow dynamics division. The study, which was presented by Kyle Davis, mechanical engineer at the centre, competed against some of the best heart-valve research units in the world.

The redesigned valve, based on the 1960s Cape Town poppet valve, has the potential to provide a low-cost solution for mechanical heart-valve replacement. It is possible to produce the titanium ring with 3-D printers and is, together with the silicon poppet valve, extremely inexpensive compared to current mechanical valve-manufacturing processes.
The advantages of this valve over current mechanical valves is that, due to the effective and laminar flow characteristics, as well as the simple locking mechanisms, there is a reduced chance of valve thrombosis, and the need for anti-clotting drugs is therefore limited.

It was also confirmed that the new valve more than meets the published FDA (Federal Drug Agency) requirements, which determine the minimum standards of valves for human use in the US.

The redesigned valve also has a very low platelet activation impact, which is responsible for platelet thrombosis and leads to valve thrombosis or strokes. This valve is another heart-valve project by the centre, which is also in the process of evaluating a tri-leaflet polyurethane valve developed by them.
