Treatment for prostate cancer leads to significant five-year declines in sexual and urinary function, according to a new study. However, general and other specific health-related quality of life factors, such as bowel function, are not affected. These findings come from the first prospective comparative study examining differences between normal aging and the effects of prostate cancer treatment, published in the November 1, 2004 issue of CANCER, a peer-reviewed journal of the American Cancer Society. A free abstract of the article will be available via the CANCER News Room upon online publication.
Generally a very slow progressing cancer, early prostate cancer is treated aggressively with radiation or radical prostatectomy. However, only one study, on surgical removal of the prostate, has proven therapeutic benefit of treatment compared with observation. Meanwhile, treatments themselves are often associated with significant adverse effects, such as impotence and urinary incontinence. To date, studies have been unable to distinguish between the normal effects of aging and the adverse effects of treatment, confounding any informed decision-making about which treatment to use.
In the first prospective comparative quality of life analysis of prostate cancer patients and matched healthy subjects, Richard M. Hoffman, M.D., M.P.H., of the New Mexico Veterans Administration Health Care System in Albuquerque, New Mexico and his colleagues compared the effects of cancer treatment versus aging in men over a five-year period.

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.
