Setså, Erling Johan; Svendsen, Øyvind Sverre; Henriksen, Bård; Stangeland, Lodve; Husby, Paul; Brauckhoff, Katrin (Journal article; Peer reviewed, 2023)Objective Vocal cord (VC) movement has been demonstrated by the use of accelerometry (ACC) to decrease in parallel with the electromyographic amplitude (EMG) during ongoing traction injury to the recurrent laryngeal nerve ... -
Allele diversity of the H-ras-1 variable number of tandem repeats in Norwegian lung cancer patients
Ryberg, D.; Tefre, T.; Skaug, V.; Stangeland, Lodve; Øvrebø, S.; Naalsund, A.; Børresen, A.-L.; Haugen, Aa. (Peer reviewed; Journal article, 1992-11)We have examined restriction fragment length polymorphisms of the H-ras-1 gene in germ-line DNA from 214 lung cancer patients and 309 unaffected controls. When DNA samples were digested with MspI/HpaII, Southern blot ... -

An experimental study on intraoperative recovery of recurrent laryngeal nerve function
Setså, Erling Johan; Svendsen, Øyvind Sverre; Husby, Paul; Heimdal, John-Helge; Stangeland, Lodve; Dahle, Geir Olav; Brauckhoff, Katrin (Journal article; Peer reviewed, 2020)Objective If bilateral thyroid surgery is planned and staged thyroidectomy considered in case of loss of neuromonitoring signal (LOS), a waiting time of 20 minutes is suggested for evaluation of early nerve recovery. This ... -
The influence of acute unloading on left ventricular strain and strain rate by speckle tracking echocardiography in a porcine model
Dahle, Geir Olav; Stangeland, Lodve; Moen, Christian Arvei; Salminen, Pirjo-Riitta; Haavestad, Rune; Matre, Knut; Grong, Ketil (Peer reviewed; Journal article, 2016)Noninvasive measurements of myocardial strain and strain rate by speckle tracking echocardiography correlate to cardiac contractile state but also to load, which may weaken their value as indices of inotropy. In a porcine ... -
