A novel non-canonical Wnt signature for prostate cancer aggressiveness
(Journal article; Peer reviewed, 2016)Activation of the Canonical Wnt pathway (CWP) has been linked to advanced and metastatic prostate cancer, whereas the Wnt5a-induced non-canonical Wnt pathway (NCWP) has been associated with both good and poor prognosis. A ... -
A particular effect of sleep, but not pain or depression, on the blood-oxygen-level dependent response during working memory tasks in patients with chronic pain
(Peer reviewed; Journal article, 2015)Background: Patients with chronic pain (CP) are often reported to have deficits in working memory. Pain impairs working memory, but so do depression and sleep problems, which are also common in CP. Depression has been ... -
A PET/MRI study towards finding the optimal [18F]Fluciclovine PET protocol for detection and characterisation of primary prostate cancer.
(Journal article; Peer reviewed, 2016)Purpose: [18F]Fluciclovine PET imaging shows promise for the assessment of prostate cancer. The purpose of this PET/MRI study is to optimise the PET imaging protocol for detection and characterisation of primary prostate ... -
A Physiological Approach to a New Decompression Algorithm Using Nonlinear Model Predictive Control
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:321, Doctoral thesis, 2011)Diving involves breathing of pressurized inert gas, which accumulates in body tissues during the dive. When the diver ascends towards the surface, the pressure is relieved and gas bubbles may form. These bubbles are the ... -
A pig model of acute right ventricular afterload increase by hypoxic pulmonary vasoconstriction
(Master thesis, 2017)Background: The aim of this study was to construct a non-invasive model for acute right ventricular afterload increase by hypoxic pulmonary vasoconstriction. Intact animal models are vital to improving our understanding ... -

A Preoperative Multimarker Approach to Evaluate Acute Kidney Injury After Cardiac Surgery.
(Journal article; Peer reviewed, 2016)Objective To investigate whether a multimarker strategy combining preoperative biomarkers representing distinct pathophysiologic pathways enhances preoperative risk assessment of acute kidney injury after cardiac surgery ... -
A Prospective Population Study of Resting Heart Rate and Peak Oxygen Uptake (the HUNT Study, Norway)
(Journal article; Peer reviewed, 2012)Objectives: We assessed the prospective association of resting heart rate (RHR) at baseline with peak oxygen uptake (VO2peak) 23 years later, and evaluated whether physical activity (PA) could modify this association. ... -
A randomised controlled study of the long-term effects of exercise training on mortality in elderly people: Study protocol for the generation 100 study
(Journal article; Peer reviewed, 2015)Introduction: Epidemiological studies suggest that exercise has a tremendous preventative effect on morbidity and premature death, but these findings need to be confirmed by randomised trials. Generation 100 is a randomised, ... -
A single simulated heliox dive modifies endothelial function in the vascular wall of ApoE knockout male rats more than females
(Journal article; Peer reviewed, 2019)Introduction: The number of divers is rising every year, including an increasing number of aging persons with impaired endothelial function and concomitant atherosclerosis. While diving is an independent modulator of ... -
A Single-Arm, Multicenter Validation Study of Prostate Cancer Localization and Aggressiveness With a Quantitative Multiparametric Magnetic Resonance Imaging Approach.
(Journal article; Peer reviewed, 2019)Objectives: The aims of this study were to assess the discriminative performance of quantitative multiparametric magnetic resonance imaging (mpMRI) between prostate cancer and noncancer tissues and between tumor grade ... -
A small molecule activator of AKT does not reduce ischemic injury of the rat heart
(Journal article; Peer reviewed, 2015)Background Activation of protein kinase AKT is required for cardioprotection by ischemic preconditioning, and transgenic overexpression of AKT protects the heart against ischemia. However, it is unknown whether acute ... -
Abdominal Aortic Aneurysm Repair: Factors influencing early and late mortality
(Doctoral theses at NTNU;2017:125, Doctoral thesis, 2017)English summary Abdominal aortic aneurysm (AAA) is a common disease that particularly affects elderly individuals (> 60 years). Open surgical repair has for several decades been regarded as the standard treatment modality ... -
Abnormal blood-brain barrier permeability in normal appearing white matter in multiple sclerosis investigated by MRI
(Journal article, 2014)Objectives: To investigate whether blood–brain barrier (BBB) permeability is disrupted in normal appearing white matter in MS patients, when compared to healthy controls and whether it is correlated with MS clinical ch ... -
Abnormal glucose regulation and coronary artery disease
(Master thesis, 2016)Abnormal glucose regulation describes a condition with disturbed glucometabolic status. Patients with this abnormality have an increased risk of developing both micro- and macrovascular complications. Patients with abnormal ... -
Absolute and relative accelerometer thresholds for determining the association between physical activity and metabolic syndrome in the older adults: The Generation-100 study
(Journal article; Peer reviewed, 2017)Background When assessing population adherence to physical activity (PA) recommendation using accelerometers, absolute intensity threshold definition is applied despite having limited validity in those with low cardiorespiratory ... -
Accelerating adaptive ultrasound imaging algorithms by means of general-purpose computing on graphics processing units
(Doctoral theses at NTNU;2014:268, Doctoral thesis, 2014)A rapid development in computer game technology and accompanying programming languages have recently provided researchers with small personal supercomputers, comprised in a single graphics processing unit (GPU). This ... -
Accuracy of breast cancer lesion classification using intravoxel incoherent motion diffusion-weighted imaging is improved by the inclusion of global or local prior knowledge with bayesian methods
(Journal article; Peer reviewed, 2019)Background Diffusion‐weighted MRI (DWI) has potential to noninvasively characterize breast cancer lesions; models such as intravoxel incoherent motion (IVIM) provide pseudodiffusion parameters that reflect tissue perfusion, ... -
