Kruppa1,2,4, Laura Bell1, Wolfgang Scharke1 1Child Neuropsychology Section, Department of Child and Adolescent Psychiatry, Psychosomatics and Psychotherapy, Medical Faculty, RWTH Aachen University, 2JARA-Brain Institute II, Molecular Neuroscience and Neuroimaging, RWTH Aachen & Research Centre Juelich, 3Lehrstuhl II für Mathematik, RWTH Aachen University, 4Translational Brain Research in Psychiatry and Neurology, Department of Child and Adolescent Psychiatry, Psychosomatics, and Psychotherapy, University Hospital Aachen The present protocol describes how to conduct fNIRS hyperscanning experiments and analyze brain-to-brain synchrony. Further, we discuss challenges and possible solutions. Medicine Isolation of Endothelial Progenitor Cells from Healthy Volunteers and Their Migratory Potential Influenced by Serum Samples After Cardiac Surgery Christoph Emontzpohl1,2, David Simons3, Sandra Kraemer4, Andreas Goetzenich4, Gernot Marx1, Jürgen Bernhagen5,6, Christian Stoppe1 1Department of Intensive Care Medicine, University Hospital Aachen, 2Institute of Biochemistry and Molecular Biology, University Hospital Aachen, 3Department of Radiology, German Cancer Research Center, 4Department of Thoracic and Cardiovascular Surgery, University Hospital Aachen, 5Department of Vascular Biology, Institute for Stroke and Dementia Research (ISD), Klinikum der Universität München, 6Deutsches Zentrum für Herz-/Kreislaufkrankheiten (DZHK), Munich Heart Alliance Endothelial progenitor cells (EPCs) are crucially involved in the neovascularization of ischemic tissues. This method describes the isolation of human EPCs from peripheral blood, as well as the identification of their migratory potential against serum samples of cardiac surgical patients. Medicine Heterotopic Auxiliary Rat Liver Transplantation With Flow-regulated Portal Vein Arterialization in Acute Hepatic Failure Karina Schleimer1, Johannes Kalder1, Jochen Grommes1, Houman Jalaie1, Samir Tawadros1, Andreas Greiner1, Michael Jacobs1, Maria Kokozidou1 1European Vascular Center Aachen-Maastricht, Department of Vascular Surgery, University Hospital RWTH Aachen Auxiliary liver transplantation provides a temporary support in acute hepatic failure, until regeneration of the failing liver. The heterotopic auxiliary liver transplantation (HALT) with portal vein arterialization (PVA) renders sufficient liver function. We developed an analogous technique in the rat, to examine the influence of the portal vein arterialization on the morphology and function of the graft.
