The term bicuspid aortal valve means that the valve between the left cardiac ventricle and the aorta has two flaps (cusps) instead of the normal three. This defect often leads to complications such as a widening of the aorta, leakage or constriction of the valve, and subsequent heart surgery. Patients with normal tricuspid aortal valves can also suffer from valve-related diseases, but not to the same extent as those with bicuspid valves.
The reason why so many people are born with a defective valve is not fully known. Nor do scientists know why only some of these patients develop problems with the valve and the aorta. More research is also needed into how these patients should undergo surgery for the best results. Researchers are inclined to favour what is known as valve-sparing surgery (which reconstructs the valve) over total valve replacement, something which they will now be examining more closely. A total of 600 patients will be taking part in the study, which is unique in its kind.
The project is led by Professor Anders Franco-Cereceda from KI’s Division of Thorax Surgery and Thorax Anaesthesiology. With him are Professor Anders Hamsten and Senior Lecturer Per Eriksson from the Atherosclerosis Research Unit at KI, Professor Kenneth Caidahl and associate professor Maria Eriksson from the Division of Clinical Physiology at KI, and associate professor Jan Liska of Karolinska University Hospital’s Thorax Clinic.
Industrialist Fredrik Lundberg is contributing a private donation of 18 million kronor (about 1.9 million euro) to the research project. Mr Lundberg is a major shareholder in Holmen, Hufvudstaden, Cardo and Industrivärden through the investment company that bears his name.
“We’re overwhelmed by his generosity, which is not only important to the actual study but also for making sure that Sweden keeps hold of its competent researchers,” says Professor Franco-Cereceda. ”This project is unique in that we’ll be looking at everything, from genetic causes to the consequences of different surgical methods and aftercare.”

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
