A study that summarizes the good work of our research team over the past three years and is part of the bachelor’s degree final project in Biomedical Engineering by Ainhoa M. Aguado, first author of the study.”Òscar Camara VIDAA, a web-based 3D interactive virtual implantation platformRelated StoriesNew method improves detection of atrial fibrillation in stroke survivorsStudy explores role of iron in over 900 diseasesMeasuring blood protein levels in diabetic patients to predict risk of strokeTo obtain the most appropriate LAAO configurations for a given patient-specific LAA morphology, the researchers created a web-based 3D interactive virtual implantation platform called VIDAA. Then, based on the features of the shape of the patient’s appendage, the researchers calculated the most promising LAAO device.Using the geometric and anatomic data of the patient’s left atrial appendage, together with the most suitable ad hoc device, volumetric meshes were built to run computational fluid dynamics simulations. Thus the researchers were able to assess estimated blood flow patterns after device implantation.Thus, by combining the VIDAA platform with computational simulations it has been possible to identify the LAAO configurations associated to a lower risk of thrombus formation and also to reveal that the positioning of the device is a key element in the creation of regions with turbulent blood flows after implantation.Source:Universitat Pompeu Fabra – BarcelonaJournal reference:Aguado,A.M. et al.

Frontiers in Physiology. doi.org/10.3389/fphys.2019.00237 Reviewed by James Ives, M.Psych. (Editor)May 16 2019According to clinical studies, about a third of patients with atrial fibrillation will suffer a stroke during their lifetime. Between 70 and 90% of these strokes are caused by a thrombus formed in the left atrial appendage.In patients with contraindications to oral anticoagulants, a left atrial appendage occluder (LAAO) is often implanted to prevent blood flow entering in the LAA. But this strategy is not without problems and often the success of the device depends on the clinician’s experience. Implementation can even lead to blood clots outside the device, eventually leading to stroke if not treated.The aim of a study, published in March in Frontiers in Physiology, was to develop tools based on biophysical models and interactive interfaces to optimize LAAO device therapies. The study was led by Òscar Camara, a researcher with the Physense Research Group, which is a part of the BCN MedTech Unit at the UPF Department of Information and Communication Technologies (DTIC).

However, researchers at the University of Bayreuth, Donghua University in Shanghai, and Nanjing Forestry University have now developed new nonwoven materials that are electrically conductive as well as flexible and breathable. This paves the way for comfortable high-tech clothes which, for example, convert sunlight to warmth, supply wearable electronic devices with electricity, or contain sensors for fitness training. The scientists have published their findings in the journal npj Flexible Electronics. Prof. Dr. Andreas Greiner’s team of researchers at the University of Bayreuth and their Chinese partners have succeeded in producing electrically conductive nonwovens which have all the other characteristics you would expect from clothing that is suitable for daily use. The materials are flexible, and thus adapt to movements and changes in posture. In addition, they are air-permeable, meaning they do not interfere with the natural breathing of the skin.The combination of these properties is based on a special production process. In contrast to common methods of production, metal wires were not inserted into finished textiles. Rather, the scientists modified classical electro-spinning, which has been used to produce nonwovens for many years: short electro-spun polymer fibres and small amounts of tiny silver wires with a diameter of only 80 nanometres are mixed in a liquid. Afterwards, they are filtered, dried, and briefly heated up. If the composition is right, the resulting nonwoven material exhibits a very high degree of electrical conductivity.This opens up a whole range of possibilities for innovative applications, especially in the area of smart clothes (i.e. wearables). Everyday clothing, for example, can be equipped with solar cells such that the captured sunlight is converted to warmth, heating up the textiles themselves. Mobile phones, cameras, mini-computers, and other wearable electronic devices could be charged by plugging them into the textiles. Sensors installed in the clothes could provide athletes and trainers with important fitness and health data or could give family and friends information on its location. “In addition to articles of clothing, similar functions could also just as easily be installed in textile materials for use in seats and instruments in cars or airplanes,” explained Prof. Dr. Andreas Greiner, Chair of Macromolecular Chemistry II at the University of Bayreuth. “Our approach, which takes the production of conductive textiles as its basis, can in principle be applied to many different systems,” added Steffen Reich, doctoral researcher and lead author of the new study. As an example, he cites current Bayreuth research projects on microbial fuel cells, which could eventually be used as electrodes in such nonwoven materials.The research findings that were published in npj Flexible Electronics resulted from close cooperation between the University of Bayreuth, Donghua University in Shanghai, and Nanjing Forestry University. It was only two years ago that the University of Bayreuth signed a cooperation agreement with Donghua University, which has had a research priority on the research and development of textiles since the establishment of the institution. The mutual exchange in research and teaching that was agreed on is now beginning to bear fruit.
U.S President Donald Trump and French President Emmanuel Macron at the 75th anniversary of D-Day at the American cemetery of Colleville-sur-Mer in Normandy, France, June 6, 2019. REUTERS/Carlos BarriaLONDON (Reuters Breakingviews) – Donald Trump has landed a pre-emptive blow in a brewing fight over how to tax technology giants like Facebook. The U.S. president on Wednesday initiated a probe into whether France’s digital levy unfairly targets American companies. The move gives him more leverage in talks about how to revamp international corporate tax but also means there’s more riding on the success of those discussions. France’s plan to impose a 3% tax on the worldwide revenue of digital groups that generate at least 750 million euros of sales globally and 25 million euros in France aims to fix what Finance Minister Bruno Le Maire calls a “fiscal injustice”: tech giants paying little tax in large European countries. Trump and other U.S. politicians, including Democrats, suspect the levy, which was approved on Thursday by the French Senate, is a cynical raid on the likes of Google parent Alphabet. The U.S. probe means there’s a risk of U.S. tariffs on French goods. Yet shares of companies like LVMH, Pernod Ricard, Kering and Airbus, whose products are imported to the United States, were little changed on Thursday. That’s probably because investors view the move as classic Trumpian posturing. The problem is, both sides have a point and may not want to give ground. Le Maire’s tax would raise about 500 million euros from 30 companies. Only one is French – advertising-technology group Criteo – and most of the rest are American, such as Alphabet, Amazon, Facebook and Apple. To the United States, that looks like discrimination, not least because European competition regulators have targeted many of the same companies with multibillion-dollar antitrust fines. At the same time, Le Maire is right to want a level playing field. International digital companies pay corporate tax in Europe at less than half the average rate of non-digital companies, according to the European Commission. And while France was in Trump’s sights on Wednesday, Britain, Austria, Spain and Italy have moved forward with digital taxes of their own. These European governments are effectively using national digital taxes as a way to press their case at the Organisation for Economic Co-operation and Development, where plans are afoot to rewrite global tax rules so that digital companies pay more tax in countries where users are based, rather than in low-tax countries like Ireland. Trump has just produced a bargaining chip of his own. But with both sides now brandishing threats, there’s a risk of a harmful spiral if the OECD talks break down. —Additional reporting by Gina Chon in San Francisco.BreakingviewsReuters Breakingviews is the world’s leading source of agenda-setting financial insight.
