This technique can potentially enhance patients' comfort and, by reducing post-operative morbidity, promote lowering the length of stay and global costs. Medicine Standardized Technique of Aortic Valve Re-implantation for Valve-sparing Aortic Root Replacement Reza Tavakoli1,2, Guillaume Lebreton1, Max Gassmann2, Peiman Jamshidi3, Pascal Leprince1 1Department of Cardiovascular and Thoracic Surgery, Pitie Salpetriere University Hospital, Assistance Publique, Hopitaux de Paris (APHP), Institut de Cardiologie, 2Institute of Veterinary Physiology and Zurich Center for Integrative Human Physiology, University of Zurich, 3Herzzentrum Hirslanden, Klinik St Anna Valve-sparing aortic root replacement has the advantage of preserving the patient's own aortic valve. The complexity of the reported techniques to date restricts their use to a limited number of cardiac surgeons. This protocol describes step-by-step a standardized technique reproducible by a greater number of cardiac surgeons. Medicine Confocal Time Lapse Imaging as an Efficient Method for the Cytocompatibility Evaluation of Dental Composites Ghania Nina Attik1, Kerstin Gritsch1,2, Pierre Colon1,3, Brigitte Grosgogeat1,2 1Laboratoire des Multimatériaux et Interfaces, UMR CNRS 5615, Université Lyon1, 2UFR d'Odontologie, Université Lyon1; Service de Consultations et de Traitements Dentaires, Hospices Civils de Lyon, 3UFR d'Odontologie, Université Paris Diderot; Service d'Odontologie, APHP, Hôpital Rothschild The most studied aspect of the biocompatibility of dental composites is their cytotoxicity 3D CLSM time lapse imaging combined with fluorescent signal quantification allows sensitive evaluation of the cell fate over time. Utilizing this method could be an efficient tool to assess the cytocompatibility of dental composites.
