Doctors in Canada have discovered that treating high-risk prostate cancer patients with radiation therapy and adding hormone therapy for more than one year allows patients to live longer, have better control of their prostate specific antigen levels and lowers the rate of death specifically from prostate cancer, according to a study published in the November 1, 2005, issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of ASTRO.
A total of 307 patients with a PSA level greater than 20 were split into two groups, both with a similar demographic of age, Gleason score and tumor stage. The first group had 151 patients receiving hormone therapy for less than 12 months (short term) and the second set had 156 patients receiving hormone therapy for more than 12 months (long term). Both groups were treated with hormone therapy in conjunction with external beam radiation therapy.
In the long-term hormone therapy group, 62.5 percent of patients showed a greater control over their PSA level, compared with 37 percent in the short-term group. The five-year overall survival rate was 87.5 percent for the long-term group and 75 percent in the short-term group. The chance of dying of prostate cancer was reduced from 18 percent to 6 percent in the long-term group.

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.
