Kovsies Women Cross-Country Team Marné Mentz, Vicky Oelofse, and Channah du Plessis
Marné Mentz, Ts’epang Sello, and Tyler Beling played a huge role in Kovsies' cross-country champions win.

After coming within a whisker of claiming the title in 2018, the University of the Free State’s (UFS) runners ensured that the University Sports South Africa (USSA) cross-country trophy comes to Bloemfontein in 2019.

Kovsies are the new national student cross-country champions after they (men and women combined) won the USSA Championships in Nelspruit on Saturday, 21 September. Kovsies and the University of Johannesburg (UJ) both finished with three gold medals at the same event in 2018. UJ finished with nine overall medals compared to the eight (three gold, two silver, and three silver) of the UFS, who had to settle for second place. In 2017, the UFS finished third.

The Kovsie women’s team played a huge role in carrying the team to the top of the medal table, winning four golds. They won the 4 km and 10 km women’s team competitions as well as the road relay. The top three places by the runners of a university determined the team winner.

USSA Cross Country Championships helped the Kovsies
win the overall title.

Marné Mentz (first), Vicky Oelofse (fifth), and Channah du Plessis (sixth) dominated the four-kilometre race. In the 10 km, Ts’epang Sello (third), Tyler Beling (sixth), and Lizandré Mulder (seventh) did enough to ensure another gold for the Free State students. Mentz, Sello, and Beling jointly took first place in the road relay.

In the 10-km race for men, Kovsies came fifth, with Victor Makhabesela the best performer (finishing ninth). Pakiso Mthembu, one of the contenders for the medal who won the silver medal at the National Cross Country Championships two weeks before, had to withdraw after 7 km in the race due to an injury.

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.
