The results of a study presented today at the American College of Cardiologys 53rd Scientific Sessions in New Orleans concludes that coronary aneurysms -- regardless of size -- are associated with a increased risk of death over a five year period and should be aggressively monitored.
The University of Chicago Hospitals and Emory Heart Center researchers studied the records of 32,372 patients undergoing coronary angiography at Emory University Hospitals in Atlanta between 1995 and 2003 and identified 276 with coronary artery aneurysms (abnormal enlargement or bulging of arteries) .The presence of an aneurysm of any size was found to have an adverse effect on long-term mortality similar to diabetes, coronary artery disease (CAD) and high cholesterol levels. "The results also show that no single risk factor -- CAD, hypertension, hyperlipidemia, diabetes, sex, or age -- was associated with the size of an aneurysm," says Emory Heart Center cardiologist Laurence S. Sperling, MD, co-author of the study. Other study authors are Timir S. Baman, MD; Jason H. Cole, MD; and Chandan M. Devireddy, MD.
"In addition, we found these patients have a predicted 5-year mortality rate of 29.1% -- a figure that is somewhat troubling, especially with the marked improvement in medical technology over recent years," Dr. Sperling, Director of Preventive Cardiology at Emory, adds. "In light of these findings, we believe all patients with angiographic evidence of coronary aneurysms should receive aggressive modification of coronary risk factors -- whether or not serious coronary disease is present. This research shows that clinicians should take all coronary aneurysms, regardless of size, seriously and monitor them aggressively."

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...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
