A 3D Reactive Collision Avoidance Algorithm for Underactuated Vehicles
Syre Wiig, Martin; Pettersen, Kristin; Krogstad, Thomas Røbekk (Journal article; Peer reviewed, 2019)This paper presents a 3D reactive collision avoidance algorithm for vehicles with underactuated dynamics. The underactuated states cannot be directly controlled, but are controlled indirectly by steering the direction of ... -
A Novel Porcine Model of Ischemia-Reperfusion Injury After Cross-Clamping the Thoracic Aorta Revealed Substantial Cardiopulmonary, Thromboinflammatory and Biochemical Changes Without Effect of C1-Inhibitor Treatment
Nielsen, Erik Waage; Miller, Yoav; Brekke, Ole Lars; Grond, Joost; Duong, Anh Hoang; Fure, Hilde; Ludviksen, Judith K; Pettersen, Kristin; Reubsaet, Leon; Solberg, Rigmor; Johansen, Harald Thidemann; Mollnes, Tom Eirik (Peer reviewed; Journal article, 2022)Ischemic injury worsens upon return of blood and innate immunity including the complement system play a central role in ischemia-reperfusion injury (IRI) as in thoracic aortic surgery. Complement component1 inhibitor ... -
Observer based path following for underactuated marine vessels in the presence of ocean currents: A global approach
Belleter, Dennis Johannes Wouter; Maghenem, Mohamed; Paliotta, Claudio; Pettersen, Kristin (Journal article; Peer reviewed, 2019)In this paper a solution to the problem of following a curved path in the presence of a constant unknown ocean current disturbance is presented. We introduce a path variable that represents the curvilinear abscissa on the ... -
Quantification of Porcine Complement Activation Fragment C3a by a Neoepitope-Based Enzyme-Linked Immunosorbent Assay
Nilsson, Per; Pettersen, Kristin; Oppermann, Martin; Skjeflo, Espen Waage; Fure, Hilde; Christiansen, Dorte; Mollnes, Tom Eirik (Peer reviewed; Journal article, 2021)Enzyme-linked immunosorbent assay (ELISA) enables fast and simple quantification of analytes in the pico- to nanogram range in complex samples. Here, we describe an ELISA for the detection of porcine C3a as a marker for ... -
Simultaneous C5 and CD14 inhibition limits inflammation and organ dysfunction in pig polytrauma
Lupu, Ludmila; Horst, Klemens; Greven, Johannes; Mert, Ümit; Ludviksen, Judith K; Pettersen, Kristin; Lau, Corinna; Li, Yang; Palmer, Annette; Qin, Kang; Zhang, Xing; Mayer, Benjamin; van Griensven, Martijn; Huber-Lang, Markus; Hildebrand, Frank; Mollnes, Tom Eirik (Peer reviewed; Journal article, 2022)Dysfunctional complement activation and Toll-like receptor signaling immediately after trauma are associated with development of trauma-induced coagulopathy and multiple organ dysfunction syndrome. We assessed the efficacy ... -
Venous Air Embolism Activates Complement C3 Without Corresponding C5 Activation and Trigger Thromboinflammation in Pigs
Storm, Benjamin; Ludviksen, Judith K; Christiansen, Dorte; Fure, Hilde; Pettersen, Kristin; Landsem, Anne; Nilsen, Bent Aksel; Dybwik, Knut Gustav; Braaten, Tonje; Nielsen, Erik Waage; Mollnes, Tom Eirik (Peer reviewed; Journal article, 2022)Introduction: Air embolism may complicate invasive medical procedures. Bubbles trigger complement C3-mediated cytokine release, coagulation, and platelet activation in vitro in human whole blood. Since these findings have ...
