Cardiologist Dr. James White and his colleagues at Western's Schulich School of Medicine & Dentistry, found CMR is a highly effective diagnostic imaging tool, identifying a cardiac diagnosis in 75 per cent of cases compared with only 50 per cent in all other testing. Overall, CMR identified a new or alternate explanation for the arrhythmia in 50 per cent of patients. The findings are published in Circulation: Cardiovascular Imaging, a Journal of the American Heart Association.
The study tested the impact of performing CMR in 82 consecutive patients that presented to hospital with either resuscitated Sudden Cardiac Death or Ventricular Tachycardia. "In these cases, there is a fear of recurrence, so we want to identify what might be at the root of the heart rhythm," explains Dr. White, the Director of the Cardiovascular MRI Clinical Research Program at Schulich's Robarts Research Institute.
Standard cardiac imaging tests were conducted in all patients. But the researchers also used a 3-Tesla MRI at the Robarts Research Institute to evaluate whether they could find an answer with one test. "What we found was interesting. In three-quarters of the patients who had an MRI performed, we were able to identify a plausible reason why that heart rhythm occurred. When we looked at the conventional testing and in only half the patients found a cause. So this made a very big and incremental difference to our diagnosis of these patients. We also found that about 50 per cent of the time, we provided either a new or alternate diagnosis for this patient population." Often the patients were found to have inflammation of the heart muscle or small heart attacks that had gone undetected.
The research was conducted in conjunction with the arrhythmia department at London Health Sciences Centre (LHSC). Dr. White is a Cardiologist and a scientist with Robarts and the Biomedical Imaging Research Centre (BIRC) at Western and Lawson Health Research Institute. He is an assistant professor in the Department of Medicine at Schulich Medicine & Dentistry and practices within the Division of Cardiology at the LHSC.
Dr. White is supported by a Clinician Scientist Award from the Heart & Stroke Foundation of Ontario. Additional funding was supplied by the Canada Foundation for Innovation and the Ontario Research Fund.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
