Rynardt and Lynique selected for SA team at World Cup
Long jumper Lynique Beneke is one of two Kovsies selected for the South African team to the inaugural Athletics World Cup.

University of the Free State (UFS) middle-distance runner, Rynardt van Rensburg, and long jumper, Lynique Beneke, have both secured a spot in the South African athletics team for the inaugural edition of the Athletics World Cup to be held in London, United Kingdom, on 14 and 15 July 2018. 

The 2018 domestic rankings were used to select the team, with one UFS athlete in each discipline set to represent the country as one of the eight competing nations at the event. Beneke, aged 27, won the long jump for women over the past two years at the national track and field championships, this year with a winning distance of 6,22 m. Van Rensburg, aged 26, won silver.

South Africa will compete against teams from the United States, Poland, China, Germany, France, Jamaica, Great Britain, and Northern Ireland. Beneke and Van Rensburg are both experienced athletes who have competed in the Olympic Games in 2016. The programme for the two-day championship does not include long-distance or combined event disciplines. Yolandi Stander, Van Rensburg, and Beneke have also been selected as part of the preliminary team for the CAA African Championships taking place in Asaba, Nigeria from 1 to 5 August 2018.

Van Rensburg recently clocked his personal best, which was also recorded as the 24th best time of the year, when he finished the Hengelo World Challenge meeting in 1:45.15.
Stander, who has a personal best of 52,81 m, won the bronze medal at this year’s nationals and a silver at the University Sports South Africa (USSA) meeting.

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.
