However, they are also more likely to lead to restenosis, a recurrence of artery clogging. According to findings in Journal of Cardiac Surgery, newly developed drug-eluting stents (DES) that release a drug directly to the injured blood vessels are less likely to lead to restenosis than traditionally used bare-metal stents (BMS). Controversy exists regarding the role of stents in the treatment of complex multi-vessel coronary artery disease and the potential for late complications.
While studies have found that DES procedures limit restenosis and, consequently, improve quality of life, the associated medical care would cost patients an average of $900 more during the two-year period following the procedure than with BMS. This cost is expected to decrease within five years, however, rendering DES cost-neutral or cost-saving when compared to BMS.
Despite the positive outcomes associated with DES, the procedure should not be viewed as a replacement for surgery. DES have proven to be safe and effective over the short and medium term, but long term effects have not been sufficiently explored.
“The impact of DES has greatly reduced the volume of coronary artery surgeries, however, the two must be regarded as complementary and not competitive strategies,” says Dr. Shahzad G. Raja, author of the study.

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...
