A new analysis shows the drug finasteride will save lives if given to men to prevent prostate cancer. Published in the April 1, 2005 issue of CANCER, a peer-reviewed journal of the American Cancer Society, the new analysis of data from the Prostate Cancer Prevention Trial (PCPT), says that any possible increase in the incidence of higher-grade tumors would be more than offset by an overall reduction in the number of prostate cancer cases in the general population.
The recent results from the PCPT represent a milestone in cancer research, showing that prostate cancer could be prevented through chemoprevention. The study found the commonly used drug finasteride reduced the incidence of prostate cancer by 24.8 percent compared to a placebo. However, a possible increase in the number of high-grade tumors in the trial prompted many to question whether any benefits of the drug would be offset by an increase in mortality related to the higher-grade tumors. No difference in mortality was seen during the 7 years of PCPT.
To explore the problem, Joseph M. Unger, M.S. and a team of researchers from the Southwest Oncology Group Statistical Center at the Fred Hutchinson Cancer Research Center in Seattle, WA analyzed Surveillance, Epidemiology, and End Results (SEER) registry data and applied the results from the PCPT.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
