Columbia University Medical Center study shows link between depression and worsening heart disease
Depression is known to be "hard on the heart" – now researchers are a step closer to understanding why. A new Columbia University Medical Center study examining potential links between depression and heart disease found that heart disease patients who showed symptoms of depression were substantially less adherent to taking a prescribed medicine than patients without depression. Patients who continued to show signs of depression three months after a heart attack or angina only took prescribed medications 67 percent of the time, compared to almost 90 percent in non-depressed patients.
The research, which was presented for the first time at the 63rd American Psychosomatic Society Annual Meeting is part of the Coronary Psychosocial Patient Evaluation Study (COPES), a multi-site, multi-project consortium that is funded by the National Heart, Lung, and Blood Institute. According to Karina W. Davidson, Ph.D., assistant professor of medicine at Columbia University Medical Center and principal investigator of the study, it was known that depression in heart disease patients increases the risk of death after a heart attack, but the explanation for the link had remained unclear until now.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
