Research published by the University of Helsinki, Finland, indicates that cytostatic and radiation therapies administered before stem cell transplantation often damage children’s permanent teeth.
Detrimental effects of cytostatic and radiation therapies on dental development have been known for a long time, but knowledge about the dental consequences of high-dose anticancer therapy preceding stem cell transplantation has so far been scarce. Päivi Hölttä, Licentiate in Dentistry, from the Institute of Dentistry, University of Helsinki, has studied the effects of high-dose anticancer chemotherapy and total body irradiation on the development of permanent teeth.
Tooth development is a genetically controlled chain of events that can be disturbed by various environmental factors. The development of permanent teeth begins as early as the 20th week of gestation and continues until the age of 14 to 15 years with the exception of wisdom teeth, which still continue their development for several years. All this time teeth are vulnerable to developmental aberrations.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
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.
