| Prof Gerhard Walzl receives A-rating from NRF | http://www.sun.ac.za/english/Lists/news/DispForm.aspx?ID=10017 | | Prof Gerhard Walzl receives A-rating from NRF | Corporate Communication & Marketing / Korporatiewe Kommunikasie & Bemarking [Alec Basson] | <p>One of Stellenbosch University (SU)'s eminent scientists, Prof Gerhard Walzl, Head of the Department of Biomedical Sciences in the Faculty of Medicine and Health Sciences, received his first A-rating from the National Research Foundation (NRF) recently. <br></p><p>Walzl's rating puts SU's total of A-rated researchers at 21 – the most ever at the institution. SU now boasts a total of 504 NRF-rated researchers. </p><p>An A-rating is the highest achievable rating for researchers on the NRF's rating system. A-rated researchers are unequivocally recognised by their peers as leading international scholars in their respective fields for the high quality and impact of recent research outputs. </p><p>A clinician scientist, trained in internal medicine, pulmonology and immunology, Walzl, who is also a Distinguished Professor, leads the multi-disciplinary Immunology Research Group in the Division of Molecular Biology and Human Genetics at SU. </p><p>He was honoured by the NRF for his outstanding research on the immunology of Mycobacterium tuberculosis (MTB) infection and in particular host biomarkers, including diagnostic markers and markers of TB treatment response and of protective immunity against MTB. </p><p>Commenting on his A-rating, Walzl said it signifies the leading role that South African scientists can and do play. He added that this is only possible through sustained collaboration both within the country and globally, and through the support of the university and South Africa and global funders of an exceptional team.</p><p>“My team is humbled by this recognition and grateful that more than two decades of hard work is seen as meaningful and cutting edge. It also shows that our research topic, immunology and biomarkers of TB, is seen as important. At the same time, we recognise that the job is not at all done and that a lot has to happen before one can say that health sciences have made a meaningful dent into the devastating TB challenge."</p><p>Prior to receiving an A-rating, Walzl was honoured by the South African Medical Research Council with a gold medal for Outstanding Lifetime Scientific Contributions to Health Research and also elected a member of the Academy of Science of South Africa in 2021. In the same year, an international research team led by him received the EDCTP (European & Developing Countries Clinical Trials Partnership) Scientific Research Team Prize.</p><p>Walzl has played a leading role in several international multisite projects funded by the Bill and Melinda Gates Foundation, the EDCTP and the US National Institute for Health. Under his leadership, the Department of Biomedical Sciences was instrumental in the recent launch of the state-of-the-art Biomedical Research Institute at SU, the most cutting-edge and advanced biomedical research complex of its kind in Africa. </p><p>Walzl has published widely on biomarkers for TB treatment response and contributed significantly to educational activities by supervising more than 30 postgraduate students during the past 15 years. He has also submitted six different patent applications, two of which were granted and four are still pending.</p><p>The NRF rating system is a benchmarking system whereby individuals who exemplify the highest standards of research, as well as those demonstrating strong potential as researchers, are identified by an extensive network of South African and international peer reviewers. Ratings are based on the quality and impact of recent research outputs (over an eight-year period).</p><ul><li>Click <a href="/english/research-innovation/Research-Development/Pages/ratedlist.aspx"><strong class="ms-rteThemeForeColor-5-0">here</strong></a><strong class="ms-rteThemeForeColor-5-0"> </strong>for a list of SU's NRF-rated researchers.<br></li></ul><p><strong>Photo by Stefan Els</strong><br></p> |

| New model sheds light on the origin of humans in Africa | http://www.sun.ac.za/english/Lists/news/DispForm.aspx?ID=9933 | | New model sheds light on the origin of humans in Africa | FMHS Marketing & Communications / FGGW Bemarking & Kommunikasie | <p>Two <a href="/english/"><strong class="ms-rteThemeForeColor-5-0">Stellenbosch University</strong></a> (SU) scientists were instrumental in the development of an evolutionary model shedding new light on questions around human origins in Africa. </p><p>This new model, recently published in the prominent journal <em class="ms-rteThemeForeColor-5-0"><a href="https://www.nature.com/"><strong class="ms-rteThemeForeColor-5-0">Nature</strong></a></em>, claims that at least two evolutionary branches of <em>Homo sapiens</em> split (but continued to mix) over hundreds of thousands of years. This so-called “weakly structured stem" (made up by a mixture of these two branches) is proposed to have contributed to the formation of an ancestral African human group, which then branched off into contemporary African populations, as well as populations living outside of Africa. </p><p>"While it is widely believed that <em>Homo sapiens</em> originated in Africa, there is uncertainty around how branches of human evolution diverged and migrated across the continent," says Marlo Möller, a professor of molecular biology and human genetics at SU's <a href="/english/faculty/healthsciences"><strong class="ms-rteThemeForeColor-5-0">Faculty of Medicine and Health Sciences</strong></a> (FMHS). “This uncertainty is due to limited fossil and ancient genomic data, and the fact that the fossil record does not always align with expectations from models built using modern DNA."</p><p>Möller and Prof Eileen Hoal, both SU scientists affiliated with the <a href="http://www.tuberculosis.org.za/"><strong class="ms-rteThemeForeColor-5-0">DSI-NRF Centre of Excellence in Biomedical Tuberculosis Research</strong></a> and the <a href="http://www.mrc.ac.za/intramural-research-units/Tuberculosis"><strong class="ms-rteThemeForeColor-5-0">SAMRC Centre for Tuberculosis Research</strong></a>, collaborated with Prof Brenna Henn, a population geneticist from the University of California, Davis, and evolution geneticist Prof Aaron Ragsdale and colleagues from the University of Wisconsin-Madison on this research. </p><p>For the study, they sequenced the genome of 44 modern Nama individuals. (The Nama people are an indigenous southern African population known to carry exceptional levels of genetic diversity compared with other modern groups.) They then tested a range of competing models of evolution and migration across Africa proposed in paleoanthropological and genetics literature, incorporating population genome data from southern, eastern, and western Africa.</p><p>The model they developed suggests the earliest population split among early humans that is detectable in contemporary populations occurred 120 000 to 135 000 years ago, after two or more weakly genetically differentiated <em>Homo</em> populations had been mixing for hundreds of thousands of years. After the split, ancient human-like species (hominis) still migrated between the stem populations, creating a weakly structured stem. </p><p>“This model offers a better explanation of genetic variation among individual humans and human groups than do previous models," says Möller.</p><p>The authors predict that according to this model, 1-4% of genetic differentiation among contemporary human populations can be attributed to variation in the stem populations. </p><p>This model may have important consequences for the interpretation of the fossil record – owing to migration between the branches, these multiple lineages were probably morphologically similar, which means morphologically divergent hominid fossils (such as <em>Homo naledi</em>) are unlikely to represent branches that contributed to the evolution of <em>Homo sapiens</em>.<br></p><p><br></p><p><em>Caption: Profs Eileen Hoal and Marlo Möller.</em><br></p> |
| A world-class biomedical research facility in Africa, for Africa | http://www.sun.ac.za/english/Lists/news/DispForm.aspx?ID=9882 | | A world-class biomedical research facility in Africa, for Africa | FMHS Marketing & Communications / FGGW Bemarking & Kommunikasie – Wilma Stassen | <p>South African Deputy Minister of Higher Education, Science and Innovation, Mr Buti Manamela, commended Stellenbosch University (SU) on its visionary leadership in establishing the cutting-edge Biomedical Research Institute (BMRI) – which will not only benefit the people of South Africa, but the entire African continent.<br></p><p>“Building on SU's long tradition of world-class research, the creation of this state-of-the-art facility is a very important milestone in our efforts to strengthen our national system of innovation, and more specifically, the health research innovation and infrastructure of both our country and our continent," Manamela said at the inauguration of SU's BMRI. This facility is the most advanced biomedical research complex on the African continent and is focussed on finding solutions to some of the most pressing health issues affecting people in South Africa and the rest of Africa.</p><p>Manamela officiated the opening of this R1,2 billion (approximately US$ 66 million) facility during a gala dinner, held last night (19 April 2023) at the BMRI on SU's Tygerberg campus in Cape Town. The event formed part of a week-long programme hosted by SU's Faculty of Medicine and Health Sciences to introduce the new facility to the public and the global and local scientific community. </p><p>“The BMRI is not just a facility – it represents a new way of doing science on the African continent. It is a symbol of our commitment to using science to create a better future for all," SU Rector, Prof Wim de Villiers said in his address. “We believe that the BMRI will be a catalyst for change, leading the way in the fight against disease and promoting the health and well-being of people throughout the continent."</p><p>The BMRI houses more than 500 biomedical researchers and students, including some of the world's foremost scientists in the fields of bioinformatics, tuberculosis, neuroscience, and urology. The leading-edge research emanating from the facility has a decidedly African focus and seeks to understand the genetic and biomolecular basis of diseases afflicting South Africa and the rest of the African continent, such as tuberculosis, HIV/AIDS and cardio-metabolic disorders.</p><p>The BMRI boasts numerous state-of-the-art laboratories, including the largest (600 m<sup>2</sup>) biosafety level 3 (BSL-3) laboratory and fully automated biorepository in Africa, a bioinformatics hub, electron microscopy laboratories, proteomics and flow cytometry services (FACS) laboratories, a medical morphological learning centre; a Sunskill laboratory, and clinical research facilities.</p><p>“We see the creation of this facility by SU as an important addition to our country's scientific resources. The research focus of the facility aligns perfectly with the objectives of government policy – the White Paper on Science, Technology and Innovation and the decadal plan – which aims to strengthen our country's national system of innovation, to the benefit of all," said Manamela.<br></p><p><br></p><p><em>Caption: Prof Wim de Villiers (SU Rector and Vice-Chancellor), Prof Elmi Muller (Dean of SU's Faculty of Medicine and Health Sciences) and Deputy Minister for Higher Education, Science and Innovation, Mr Buti Manamela, cutting the ribbon at the BMRI's inauguration.</em><br></p><p><em>Photo credit: Nardus Engelbrecht</em><br></p> |
| Improving lives with breakthroughs in biomedical sciences | http://www.sun.ac.za/english/Lists/news/DispForm.aspx?ID=9862 | | Improving lives with breakthroughs in biomedical sciences | Gerhard Walzl | <p>A leading-edge biomedical research facility, the Biomedical Research Institute (BMRI), is being launched by Stellenbosch University (SU) this week. In an opinion piece for the <em>Daily Maverick </em>(13 April 2023), Prof Gerhard Walzl, Head of the Department of Biomedical Sciences at SU's Faculty of Medicine and Health Sciences, explains why this R1,2 billion investment in biomedical sciences is important, and what it will mean for Africa. </p><ul><li><p>Read the article below or click <a href="https://www.dailymaverick.co.za/article/2023-04-13-stellenbosch-university-unveils-r1-2-billion-investment-in-biomedical-science-for-africa/"><strong class="ms-rteThemeForeColor-5-0">here</strong></a><strong class="ms-rteThemeForeColor-5-0"> </strong>for the piece as published.</p></li></ul><p><strong>The case for biomedical sciences</strong><br></p><p>Doctors, nurses, and other healthcare workers are most often viewed as the heroes of healthcare. And while they undoubtedly play a crucial role in delivering treatment to patients (often selflessly and courageously under difficult circumstances), this paradigm does not account for the multitude of scientists and thousands of laboratory hours behind the research and development of every tablet, injection or medical device used to treat you, the patient. </p><p>To use a cycling metaphor – if healthcare workers are the cyclists, biomedical science is not only the bicycle they're riding, but also the road, the road map, the construction worker who built the road, and the town planner who designed it.</p><p>Biomedical research has long been at the heart of sweeping changes to the practice of medicine and underpins new ground-breaking developments. </p><p>Immediately coming to mind is Sir Alex Fleming's almost forgotten Petri dish that led to the discovery of penicillin – the antibiotic touted as having saved more than 200 million lives over the past eight decades. Or the discovery of insulin and consequent scientific developments enabling mass production of this hormone, making it accessible to millions of type 1 diabetes patients whose lives would otherwise have been cut short. </p><p>More recent developments include the development of 3D-printed medical devices that have revolutionised some fields of medicine. Some of the applications in use today include 3D-printed skin for burn victims; airway splints for lungs; noses and ears for cancer patients; heart valves; joint implants; and functional artificial hands. Experimentally, spontaneously beating 3D-printed hearts have been produced, albeit for rabbits. In future, such developments could be game changers for the treatment of life-threatening conditions, like heart failure. </p><p>Biomedical science concerns itself with finding answers to medical questions and provides pieces of the puzzle that have been essential for the progress that we have seen over the past 100 years, accelerating dramatically over the past few decades.</p><p>Taken together, there are too many applications of biomedical sciences to mention. All preventive, diagnostic, therapeutic or treatment monitoring interventions have been channelled through biomedical science processes. This includes vaccines, pain killers, new cancer treatments, contraceptives, antibiotics, nutritional support, cholesterol-lowering drugs, heart failure drugs, immune suppressive drugs, organ transplantation-related drugs and many more.</p><p><strong>Biomedical science </strong><strong><em>in</em></strong><strong> Africa</strong></p><p>In South Africa, biomedical science was thrust onto the international stage during the recent Covid-19 pandemic, when genomic surveillance – conducted right here on the Cape Flats – enabled South African scientists to quickly identify the Beta and Omicron variants of SARS-CoV-2 and warn the rest of the world about the impending threat.</p><p>Covid-19 will not be the last pathogen to cause epidemics and pandemics. As was evident during the last epidemic, there are significant barriers to the rapid availability and sharing of available genomic data. The Network for Genomic Surveillance in South Africa (NGS-SA), established by Prof Tulio de Oliveira, a key member of the BMRI, allows the combination of near-real time genomic surveillance data with other epidemiological data and to rapidly analyse the data to produce actionable information for public health officials and policymakers. </p><p>Clear communication lines between scientists and policy makers in South Africa, Africa and the rest of the world will be essential for rapid responses, the formulation of public health interventions and monitoring of future pandemics, to prevent a repetition of the devastating economic and public health consequences that were seen during the Covid-19 pandemic.</p><p><strong>Biomedical science </strong><strong><em>for</em></strong><strong> Africa</strong></p><p>Africa has its own set of health challenges and needs to develop its own solutions that take African realities into account. These include a lack of infrastructure, such as transportation and cold chain challenges, affordability, disease profiles, such as higher prevalence of infectious diseases like TB, malaria and HIV and population genetic make-up. </p><p>Simply relying on solutions developed in other areas for their own realities will not ensure that the most appropriate solutions are researched or adopted. Africa should not only be the recipient of biomedical technology, but also a provider of solutions. An investment in biomedical research, which is dedicated to understanding the genetic and bio-molecular basis of disease with a decidedly African focus, will play a significant role in achieving this.</p><p>In addition, African researchers have a lot to offer to the world of biomedical sciences, particularly in the field of infectious diseases, where ground-breaking research on SARS-CoV-2, HIV and TB is being conducted. The BMRI will allow significant human capacity development through training some of the best students from the continent and exposing them to extensive national and international research networks to result in a next generation of successful scientists. </p><p><strong>Investing in biomedical science in and for Africa</strong></p><p>Against the background of the many medical breakthroughs that have saved countless lives, SU's investment of R1,2 billion in the BMRI is of huge significance for South Africa and the rest of Africa. </p><p>The more than 500 scientists at the BMRI conduct research which translates into discoveries that help improve the diagnosis, prevention and treatment of illnesses contributing most to morbidity and mortality in South Africa and Africa<em>. </em></p><p>The<em> </em>BMRI consists of several state-of-the-art laboratories, including electron microscopy, proteomics, molecular biology, genetics, immunology, microbiology and FACS laboratories (for fluorescence-activated cell sorting); the largest fully automated biorepository on the African continent; a bioinformatics hub; and a clinical research unit. It also hosts the SUNSkill facility that offers advanced surgical training to local and international specialists.</p><p>The immense value of the BMRI was recognised even before its completion in 2023, and high-profile visitors, including President Cyril Ramaphosa and WHO Director-General Dr Tedros Adhanom Ghebreyesus, came to view the facility in 2022. </p><p>The facility's potential was endorsed when the Centre for Epidemic Response and Innovation (CERI), located in the BMRI, was selected by the WHO as a partner-member of the first Covid mRNA Vaccine Technology Transfer Hub. </p><p><strong>The bicycle and the cyclist</strong></p><p>But back to the cycling metaphor: Just like the bicycle would mean nothing without a willing and able cyclist, the solid foundation that biomedical sciences provide would be nothing without healthcare workers taking it to patients in need. <br></p><p><br></p> |

BSL-3 laboratories are designed to be easily decontaminated. </li><li>A system of negative air pressure keeps hazardous fumes or airborne toxins from flowing out of laboratories and into adjacent areas. A powerful ventilation and filtration plant continuously draw air out of laboratories and to the top of the building, where it is filtered and released.</li><li>The BMRI boasts advanced energy recovery technology fitted to the air system that reduces the building's carbon footprint compared to other similar buildings.</li></ul><p> </p><p><em>Click </em><a href="/english/faculty/healthsciences/biomedical-research-institute/Pages/Groups.aspx"><em>here</em></a><em> for more information on the research being conducted at the BMRI.</em></p><p><em>Click </em><a href="/english/Lists/Events/DispForm.aspx?ID=5476"><em>here</em></a><em> for more information about the BMRI launch activities taking place over the next week.</em></p><ul><li><em>Click </em><a href="/english/faculty/healthsciences/biomedical-research-institute/Pages/Resources.aspx#GB"><em>here</em></a><em> for a link to photos, videos and soundbites</em></li></ul><p><em><br></em></p><p> </p><p> </p><p><br></p> |
| Doctoral study can help prevent spreading of bovine TB in African buffaloes | http://www.sun.ac.za/english/Lists/news/DispForm.aspx?ID=9830 | | Doctoral study can help prevent spreading of bovine TB in African buffaloes | Corporate Communication & Marketing / Korporatiewe Kommunikasie & Bemarking [Alec Basson] | <p>A researcher at Stellenbosch University (SU) has found an innovative way to diagnose bovine Tuberculosis (TB) in African buffaloes and identify infected animals more accurately and rapidly. <br></p><p>This can help to prevent the spread of the disease in one of the continent's most iconic and high-valued species.<br></p><p>“It is essential to diagnose bovine TB quicker and to accurately identify infected buffaloes early because these animals keep the disease-causing bacteria in the ecosystem, which can cause infection of other species such as lions, wild dogs, rhinos, elephants, and antelopes," says Dr Charlene Clarke from the DST/NRF Centre of Excellence for Biomedical Tuberculosis Research in the Faculty of Medicine and Health Sciences at SU. <br></p><p>“This could negatively impact wildlife tourism, the economy, and conservation programmes," cautions Clarke, who obtained her PhD in Molecular Biology on Tuesday 28 March 2023 at one of SU's March graduation ceremonies. <br></p><p>For her doctorate, Clarke combined molecular and immune-based tests to help improve the diagnosis of bovine TB in buffaloes. She says current strategies to eradicate bovine TB require the testing of animals, followed by the culling of infected animals.<br></p><p>As part of her study, Clarke collected tissue and swab samples from the mouths and noses (oronasal) of infected animals while they were immobilised. She also collected oronasal swabs from buffaloes that tested negative for bovine TB. These swabs also allowed her to identify and characterise nontuberculous mycobacteria (NTMs) species in buffaloes. All the swab samples were stored in a medium that inactivates all pathogens and stabilises the DNA, thereby rendering them safe to handle.<img src="/english/PublishingImages/Lists/dualnews/My%20Items%20View/Clarke-fieldwork.jpg" alt="Clarke-fieldwork.jpg" class="ms-rtePosition-2" style="margin:5px;width:505px;height:377px;" /><br></p><p>Clarke then used these inactivated samples together with a human TB diagnostic test to detect the presence of <em>Mycobacterium bovis</em> DNA in buffaloes. <em>M. bovis</em> causes bovine TB in wildlife and livestock species. She says her study is the first to combine these methods for the detection of bovine TB in buffaloes.<br></p><p>“We found that the combined use of swab samples, stored in a pathogen-inactivating medium, and the test used to diagnose TB in humans made it possible to accurately and rapidly identify <em>M. bovis</em> infected buffaloes, while ensuring the safety of the humans who handle samples that potentially contain zoonotic bacteria.<br></p><p>“We further found that there is a great diversity of NTM species present in buffaloes, some of which seem to cause false positive bovine TB test results in these animals. The wide diversity of NTMs in buffaloes identified in this study provides a foundation for further research to investigate their role in wildlife bovine TB diagnostic testing and host immune responses.</p><p>“This novel approach provided a safe sampling method and quick, accurate results, making it possible to bypass the requirement for costly and laborious tests of mycobacterial tissue grown in a laboratory for diagnosis."<br></p><p>Clarke adds that the human TB diagnostic test, which is available in many developing countries with African buffalo populations, could potentially minimise the need to transport samples from remote locations to specialised laboratories for bovine TB diagnosis. It could also provide same-day results to diagnose infected buffaloes. Currently, it takes more than two months before results from tissue grown in the laboratory are ready.<br></p><p>Clarke says her study is important given the factors that complicate accurate diagnosis in buffaloes, such as the confirmation of infection by mycobacterial isolation from tissue grown in a laboratory, which relies on time-consuming methods with limited sensitivity; exposure of buffaloes to more than 250 NTMs that are closely related to <em>M. bovis</em>; and the inappropriate interpretation of diagnostic tests. </p><p>“The presence of NTMs, for example, can cause false-positive test results which can lead to the unnecessary loss of animals due to culling, and quarantine of the farm on which 'positive' animals were identified." <br></p><p>Going forward, we need to continuously improve the diagnostic tools for accurately identifying infected buffaloes at early stages of infection, before they shed bacteria and transmit it to other animals, concludes Clarke. <br></p><p>“The development of new molecular-based tools that are used directly on collected samples is a step in the right direction, as it significantly improves the accurate detection of infected animals at a faster turnaround time than culture-based tests, thereby giving same-day results. This will dramatically improve disease control strategies in the quest towards eradicating bovine TB in South Africa."<br></p><p><strong>Photo</strong>: Dr Charlene Clarke at the graduation ceremony. <strong>Photographer</strong>: Stefan Els<br></p><p><strong>Photo 1</strong> (supplied): Dr Charlene Clarke and fellow researcher Dr Wynand Goosen collecting samples.<br></p><p> </p><p><br></p><p><br></p> |
