Removing the aortic and pelvic lymph nodes during surgery for advanced ovarian cancer improves progression-free survival but not overall survival, according to a new study in the April 20 issue of the Journal of the National Cancer Institute.
Ovarian cancer is the fifth most common cancer in women worldwide. In the United States, about 25,000 women were diagnosed with the disease in 2004 and 16,000 women died from it. Long-term survival is possible after surgery and chemotherapy, but only about 30% of patients with advanced ovarian cancer survive 5 or more years after diagnosis. Retrospective studies have suggested that lymphadenectomy--the removal of the aortic and pelvic lymph nodes during cytoreductive surgery to remove the cancer--may improve survival, but the value of the procedure remains controversial.
To determine whether systematic aortic and pelvic lymphadenectomy improves progression-free and overall survival, Pierluigi Benedetti Panici, M.D., of "La Sapienza" University in Rome, and colleagues conducted a clinical trial in which 427 patients with advanced ovarian cancer were randomly assigned to undergo either primary cytoreductive surgery followed by lymphadenectomy or cytoreductive surgery only. The patients were followed for an average of 68.4 months.

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.
