A high-sugar diet is seen as a risk factor for obesity and chronic illness. University of Bonn researchers have analyzed data on sugar intake among children and adolescents in a long-term study, finding that intake has been declining steadily since 2010—but is still above the level recommended by the World Health Organization (WHO). The results, to be published in the European Journal of Nutrition, is already available online.
What distinguishes the growth and development patterns of early mammals of the Jurassic period? This is the question jointly investigated by researchers of Queen Mary University of London and the University of Bonn. Paleontologists have been able to gauge the lifespan and growth rates of these ancient animals, and even when they reached sexual maturity, by studying growth rings in fossilized tooth roots. The study has now been published in the journal Science Advances.
The University of Bonn is expanding exchange opportunities for students and employees. This year’s call for proposals for the Erasmus+ Worldwide Exchange Programme has resulted in the University acquiring two additional scholarship projects with partner universities in Armenia and Georgia. These come in addition to the existing partnerships with universities in four countries.
Food in hospitals often does not enjoy a good reputation. The proportion of meat on the plate in particular is too high and often does not meet the recommendations of the German Nutrition Society (DGE), which advocates a more plant-based diet in hospitals (in German). Clinics can do a lot to motivate patients to choose a healthier menu, as two new studies by Bonn University Hospital (UKB) and the University of Bonn show. Around 2,000 people took part. The results can now serve as a basis for decision-makers in hospitals to make culinary changes. The results of the study will be published in the current August issue of the “Journal of Environmental Psychology”.
The innermost layer of blood vessels is formed by endothelial cells, which in turn play a role in the development of diseases of the cardiovascular system. Human endothelial cells are therefore required for the "in vitro" investigation of the causes of these diseases. Researchers at the University Hospital Bonn (UKB) and the University of Bonn have now established a highly efficient, cost-effective and reproducible way to generate functional endothelial cells from human induced pluripotent stem cells (hiPSCs) for tests in cell culture dishes. The results of the study have now been published in the journal " Cardiovascular Research".
The Argentinian archaeologist Professor Gustavo Politis is to receive a research prize from the Humboldt Foundation. Among other things, the researcher is studying the early settlement of the Americas. Professor Carla Jaimes Betancourt from the Department of Anthropology of the Americas at the University of Bonn had put his name forward for the €60,000 award. The pair are now stepping up their collaboration.
The University of Bonn in partnership with Santander Germany has awarded two students a Uni Bonn Sorgenfrei Stipendium Powered by Santander Universities (“Worry-free Scholarship”). The fortunate winners, Zilan Erol and Corinne Oetker-Álvarez, are each to receive 5,000 euros in scholarship funds.
Whether or not a person becomes seriously ill with COVID-19 depends, among other things, on genetic factors. With this in mind, researchers from the University Hospital Bonn (UKB) and the University of Bonn, in cooperation with other research teams from Germany, the Netherlands, Spain and Italy, investigated a particularly large group of affected individuals. They confirmed the central and already known role of the TLR7 gene in severe courses of the disease in men, but were also able to find evidence for a contribution of the gene in women. In addition, they were able to show that genetic changes in three other genes of the innate immune system contribute to severe COVID-19. The results have now been published in the journal "Human Genetics and Genomics Advances".
