Here, an optimized protocol for basophil activation test is used to investigate drug hypersensitivity. A method for the efficient production of covalent drug-protein conjugates and their physicochemical characterization is described. Medicine Microsurgical Venous Pouch Arterial-Bifurcation Aneurysms in the Rabbit Model: Technical Aspects Camillo Sherif*1,2,3, Javier Fandino*2,4, Salome Erhardt2,4, Antonio di Ieva5, Monika Killer6, Guenther Kleinpeter1, Serge Marbacher2,4 1Department of Neurosurgery, Hospital Rudolfstiftung, 2Department of Neurosurgery, Kantonsspital Aarau, 3Cerebrovascular Research Group, Department of Biomedical Research, Medical University of Vienna, 4Cerebrovascular Research Group, Department of Intensive Care Medicine, University of Berne, 5Centre for Anatomy and Cell Biology, Department of Systematic Anatomy, Medical University of Vienna, 6Department of Neurology, Paracelsus University Salzburg An optimized technique for the microsurgical creation of arterial bifurcation aneurysms mimicking bifurcation human cerebral aneurysms is described. A venous pouch is sutured into an artificially created true bifurcation of both common carotid arteries. Facilitated microsurgical techniques and aggressive postoperative anticoagulation and analgesia lead to minimized morbidity rates and high aneurysm patency rates.
