The widely used erectile dysfunction drug Levitra is now the second drug in its class found to protect the heart against tissue damage following acute heart attack, according to a new study by Virginia Commonwealth University researchers.
“Our findings further support the concept that the novel class of phosphodiesterase-5 inhibitors, or PDE-5 inhibitors, including Levitra and Viagra, may have a new utility in cardiac protection, in addition to their well-known use for the management of erectile dysfunction in men,” said Rakesh C. Kukreja, Ph.D., professor of medicine, physiology, biochemistry and emergency medicine at VCU. Kukreja is lead author of the study.
In the study, currently available online and to be published in the March issue of the Journal of Molecular and Cellular Cardiology, Kukreja and his team demonstrated for the first time that pretreatment with a clinically relevant dose of Levitra, generically known as vardenafil, induces a protective effect against heart attack injury by opening the mitochondrial KATP channel in an animal model. The Journal of Molecular and Cellular Cardiology is the official publication of the International Society for Heart Research.

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.
