One of the nations leading cardiovascular medical researchers has issued a call for less aggressive direct-to-consumer advertising and better safety assurances of medications in a special article posted online today by JAMA because of its relevance to the recent withdrawals and warning labels on the pain-relieving drugs known as COX-2 inhibitors. The article will be published in a print edition of JAMA in early 2005.
Eric J. Topol, M.D., from the Cleveland Clinic Foundation, writes that the cardiovascular risks of the various coxib drugs were not well-studied in clinical trials. "Based on data available in 2001 for celecoxib and rofecoxib, my colleagues and I concluded: it is mandatory to conduct a trial specifically assessing cardiovascular risk and benefit of these agents. Until then, we urge caution in prescribing these agents to patients at risk for cardiovascular morbidity. Unfortunately, no such trials were ever initiated and the official warnings for the coxib drugs took years to materialize."
"Importantly, providing more authority to the FDA (Food and Drug Administration) to shape and require the execution of vital trials is perhaps the most important lesson from the coxibs," Dr. Topol writes.

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.
