Prof Frank Zachos
Prof Frank Zachos recently delivered his inaugural lecture on the UFS Bloemfontein Campus.

Prof Frank Zachos, a scientist and Head of the Mammal Collection at the Natural History Museum (NHM) in Vienna – one of the world’s largest natural history museums – recently delivered his inaugural lecture at the University of the Free State (UFS) on the Bloemfontein Campus.

His lecture was titled: Of bat bombs and super moms – the wondrous and wondrously curious world of mammals.

Prof Zachos, an affiliated researcher at the UFS, says he chose mammals as the topic of his lecture because he is a mammalogist and curator of mammals at the Natural History Museum. Additionally, he collaborates with Prof Paul Grobler, Head of the Department of Genetics, on mammal projects.

Exposure to almost unparalleled biodiversity in SA

With a mixture of entertaining fun facts and some proper research results, he presented his lecture, providing an overview of some of the most interesting aspects of mammals. These included their different ways of reproduction: the platypuses laying eggs, the tiny marsupial offspring growing in a pouch, and placental mammals having long gestation times. Furthermore, he compared levels of biodiversity in South Africa and Europe and highlighted some particularly bizarre mammals, such as the aye-aye, naked mole-rat, the platypus, and two extinct South African ungulates from their collection in Vienna – the quagga and the blue antelope.

Prof Zachos also discussed his own research on blue antelope genetics, as well as research on other species, in the context of the detrimental impact humans have on mammals and other wildlife.

Moreover, his lecture included a reference to Project X-Ray, a story of how the US army pursued an unsuccessful plan to use bats as carriers of mini bombs in World War II.

Prof Zachos, who is specifically known for his research on the systematics, biogeography, and genetics of red deer, as well as his theoretical work on the species problem (‘what is a species?’ –  one of the most hotly debated topics in evolutionary biology), is affiliated with the UFS due to his longstanding collaboration with Prof Grobler. He says they have known each other for a long time, have published together, and that he has also served as an external reviewer for several theses coming from the Department of Genetics.

“Apart from this personal connection, what made this collaboration particularly interesting to me from a professional viewpoint, is the rich wildlife biodiversity and the research focus of Prof Grobler’s research group, which overlaps significantly with my own longstanding interests,” adds Prof Zachos.

“Working with Prof Grobler, I am involved in studies on the genetic diversity and structuring of different mammal species occurring in South Africa. The opportunity to spend time in the field for sample collection and other activities is definitely also a highlight,” remarks Prof Zachos.

Ideal combination of academic and personal growth

Regarding his connection with the UFS and its impact on shaping the future direction of his research, he states that he has a strong interest in antelopes – a group of mammals not found in Europe, but very prominent in South Africa. “Apart from that, people in the Department of Genetics have expertise in relevant areas that I personally do not have, for example bioinformatics. For me, it is the ideal combination of academic and personal growth, and I am very grateful to have this unique opportunity.”

He believes that his affiliation with the UFS and its Department of Genetics will continue to provide him with opportunities to expand his research and knowledge to different species and ecosystems.

Beyond science, he says that he has developed an interest in the country as well. “I have been reading books about South Africa, and I consider myself very privileged to have a second academic home here, which gives me the opportunity for exchange with people of different backgrounds,” he comments.

UFS Doctors make History in South Africa
2011-07-14

 

New aortic valve

Three members of our Faculty of Health Sciences made history by being the first to implant a special new aortic valve in South Africa. 
 
In a combined effort, the Departments of Cardiology, Pediatric Cardiology and Cardiothoracic Surgery did the first Medtronic CoreValve implant in South Africa on a patient in Universitas Academic Hospital. 
 
With the support of hospital management and the Medtronic company, Prof. Hennie Theron, Prof. Stephen Brown and Dr JP Theron of the Faculty of Health Sciences, with the assistance of Dr Jean-Claude Laborde, performed the operation early on Wednesday morning, 06 July 2011.
 
The advantage of this new valve is that it can be implanted percutaneously through a catheter from the groin. This eliminates the need for invasive surgery.
 
The valve is made from porcine pericardium (tissue derived from pigs) and is mounted on an expandable stent, which is threaded along an artery, until it reaches its desired position. Prof. Theron says the valve is especially useful in older patients who suffer from aortic valve disease and pose a high surgical risk. Furthermore, the use of this valve greatly reduces hospitalisation time, in comparison to traditional surgery.
 
“One patient already received an implant this morning and we hope to finish 2 more today,” Prof. Brown said, emphasizing the swiftness and efficiency of the new valve implanting process.
 
“It is a complex procedure, but this service can in future be offered to all patients in the public and private sectors of the Free State. It is heartwarming that the academic complex can take the lead in this modern, high-tech therapy.”
 
For more information on the procedure, please contact Prof. Theron at 051 4053428.
