Rat Model of the Associating Liver Partition and Portal Vein Ligation for Staged Hepatectomy (ALPPS) Procedure Erik Schadde1,2,3, Martin Hertl2, Stefan Breitenstein3, Beatrice Beck-Schimmer1,4, Martin Schläpfer1,4 1Institute of Physiology - Center for Integrative Human Physiology, University of Zurich, 2Department of Surgery, Rush University Medical Center, 3Department of Surgery, Cantonal Hospital Winterthur, 4Institute of Anesthesiology, University and University Hospital Zurich Inducing rapid liver hypertrophy using Associating Liver Partition and Portal vein ligation for a Staged hepatectomy (ALPPS) has been proposed for resection of borderline resectable liver tumors. This model may elucidate mechanisms involved in rapid hypertrophy and allows testing of drugs that promote or block the acceleration of regeneration.
Roux-en-Y Gastric Bypass Operation in Rats Marco Bueter1,2, Kathrin Abegg2,3, Florian Seyfried4, Thomas A. Lutz2,3, Carel W. le Roux4 1Department of Surgery, University Hospital Zürich, 2Zürich Centre for Integrative Human Physiology, University of Zürich, 3Institute of Veterinary Physiology, Vetsuisse Faculty, University of Zürich, 4Imperial Weight Centre, Department of Investigative Medicine, Imperial College London Numerous studies using gastric bypass rat models have been recently conducted to uncover the underlying physiological mechanisms of Roux-en-Y gastric bypass operations. This article aims to demonstrate and discuss the technical and experimental details of our published gastric bypass rat model to understand advantages and limitations of this experimental tool.
Implantation of Radiotelemetry Transmitters Yielding Data on ECG, Heart Rate, Core Body Temperature and Activity in Free-moving Laboratory Mice Nikola Cesarovic1, Paulin Jirkof2, Andreas Rettich2, Margarete Arras1 1Division of Surgical Research, University Hospital Zurich, 2Institute of Laboratory Animal Science, University of Zurich A surgical technique for implantation of commercially available telemetry transmitters used for continuous measurement of biopotential (one-lead ECG), heart rate, core body temperature and locomotor activity in freely moving mice is shown. Recommendations and protocols for post-operative care and pain relief, improving recovery, well being and survival rate are also presented.
