Doctors in Brazil have concluded that the drug amifostine eases many of the most common side effects associated with patients receiving radiation therapy to treat their cancer while simultaneously making the cancer more susceptible to radiation. The study was published in the March 1, 2006, issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of ASTRO, the American Society for Therapeutic Radiology and Oncology.
The researchers set out to evaluate, via a clinical investigation of already published work, whether adding amifostine to radiation therapy would prevent common side effects, such as mouth dryness, difficulty swallowing, lung inflammation, bladder inflammation, problems with the esophagus and inflammation of the mucous membranes. In some cases, these side effects can be severe enough that the patients treatment has to be suspended or stopped completely – potentially preventing their cancer from being completely cured. The other major purpose of the study was to discover if amifostine would inadvertently protect the tumor from radiation.
The investigators narrowed their research to 14 randomized, controlled trials in which 1,451 patients were split into two groups: one receiving radiation therapy alone and the second receiving radiation therapy in addition to amifostine. Patients taking amifostine were shown to have less radiation-related side effects. The research also showed that the drug did not protect the tumor from the radiation therapy and patients receiving the drug were more likely to have their cancer affected by the radiation than patients not given amifostine.

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...

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...
