A drug used for the treatment of sickle cell anemia in adults has now been shown to cause significant improvements in very young children with the disorder. The finding is an important one as these young patients are especially vulnerable to serious organ failure and even death at an early age. The study results will be published in the October 1, 2005, issue of Blood, the official journal of the American Society of Hematology.
Sickle cell anemia is a genetic blood disorder that can cause severe pain, fatigue, and organ damage to the kidneys, spleen, and liver. It occurs in about one in every 500 African-Americans. In the new study, 21 children from two to four years old who had sickle cell anemia were given the drug hydroxyurea orally as a flavored liquid formula. A majority of the children took the drug for at least four years and more than half of the participants completed all six years of the study.
The treatment was well-tolerated in the patients, with only one childs dosage permanently reduced during the study due to adverse effects. The drugs primary function, to counteract the effects of the disease by increasing and sustaining fetal hemoglobin production, was achieved in all study participants. Patients treated with hydroxyurea also weighed more and were taller than untreated children with the disorder – their growth rates were even comparable to those of normal children.

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.
