Young researcher to jet out to UK

When Mamosa Ngcala jets out to the United Kingdom (UK) on 31 July 2018, she will not only be doing research and improving herself academically at the Durham University, but she will also put yet another feather in the growing research profile cap of the Qwaqwa Campus.

“I am looking forward to my study visit under the mentorship of Dr Steve Chivasa, my supervisor’s co-researcher in the Department of Biosciences at the renowned Durham University. This will enable me to grow academically as much as it will get me closer to concluding my research on climate change and food security,” said Mamosa, a master’s student in Science (Botany). Her supervisor is Dr Rudo Ngara.

“Going there will fast-track my research that looks at how food security can be enhanced in as far as growing sorghum is concerned. This study in Plant Biotechnology aims to identify heat responsive genes in sorghum, which is the fifth most important cereal crop in the world. The information obtained in this study will serve as fundamental knowledge regarding molecular responses of plants to heat stress and will be used in breeding programmes to develop crops that can tolerate high temperature stress conditions caused by climate change, thus resulting in high crop yield in agriculture as well as food security,” she said. She will be in the UK until 12 September 2018.

Mamosa has recently won the 3-Minute thesis competition for graduates that was part of the ‘Sorghum in the 21st Century’ international conference held in Cape Town.

Talking about this achievement, she said: “Going head-to-head with PhD students from all over the world gave me extra motivation and drive to do well, and I did. This goes to show that we can achieve whatever we put our minds to. Having to summarise my entire study in three minutes for a non-specialist audience, using one PowerPoint slide, was a challenge that had to be overcome,” said Mamosa. The conference was organised by the Collaborative Research on Sorghum and Millet and the University of Pretoria.

Mamosa graduated with distinction in Botany for her honours degree. She is a member of the Golden Key International Honour Society and Chairperson of the Postgraduate Student Council and is looking forward to advancing her studies to PhD level.

Medical team performs first hybrid procedure in the Free State
2014-12-08

The days when a heart operation meant hours in an operating theatre, with weeks and even months of convalescing, will soon be something of the past.

A team of cardiologists from the University of the Free State’s (UFS) Faculty of Health Sciences once again made medical history when they performed the first hybrid procedure in the Free State.

The Department of Paediatric Cardiology, in conjunction with the Department of Cardiothoracic Surgery, performed this very successful procedure on a 45-year-old woman from Kuruman.

During the procedure of 30 minutes, the patient’s thorax was opened up through a mini thoracotomy to operate on the beating heart.

“The patient received an artificial valve in 2011. Due to infection, a giant aneurism developed from the left ventricle, next to the aorta. Surgery would pose a very high risk to the patient. Furthermore, her health was such that it would contribute to problems during open-heart surgery,” explains Prof Stephen Brown, Head of the UFS’s Department of Paediatric Cardiology.

“After the heart was opened up through a mini thoracotomy, the paediatric cardiologists performed a direct puncture with a needle to the left ventricle cavity. A Special sheath was then placed in the left ventricle to bypass the catheters. Aided by highly advanced three-dimensional echocardiography and dihedral X-ray guidance, the opening to the aneurism, located directly below the artificial aorta valve, was identified and the aneurism cannulated.”
 
During the operation, a special coil, called a Nester Retractor, was used for the first time on a patient in South Africa to obtain stasis of extravasation and ensure the stability of devices in the aneurism.

“This is highly advanced and specialist work, as we had to make sure that the aneurism doesn’t rupture during manipulation and the devices had to be positioned in such a way that it doesn’t cause obstruction in valve function or the coronary artery. The surgical team was ready all the time to switch the patient to the heart-lung machine should something go wrong, but the procedure was very successful and the patient was discharged after a few days.”
