Metacognitions are associated with subjective memory problems in individuals on sick leave due to chronic fatigue
(Peer reviewed; Journal article, 2016)Background: Subjective cognitive impairments are frequent, but poorly understood in patients with chronic fatigue. We hypothesized that maladaptive metacognitive beliefs at baseline were associated with baseline subjective ... -
Metacognitive Beliefs as Predictors of Return to Work After Intensive Return-to-Work Rehabilitation in Patients With Chronic Pain, Chronic Fatigue and Common Psychological Disorders: Results From a Prospective Trial
(Peer reviewed; Journal article, 2020)Background: Metacognitions are associated with work status, but no research has examined to what extent metacognitions before treatment and change in metacognitions following treatment predict return to work (RTW) ... -
Metal Artifact Reduction for Total Hip Replacement in MRI
(Master thesis, 2019)Projektets baggrund: Philips 1.5 T-scanneren gennemgik en hardware-og softwareopgradering. Under denne proces var nogle af protokollerne ikke blevet opgraderet. Den gyldne standard pseudotumor hofte protokol bestod af 4 ... -
Method for Designing Semantic Annotation of Sepsis Signs in Clinical Text
(Chapter, 2023)Annotated clinical text corpora are essential for machine learning studies that model and predict care processes and disease progression. However, few studies describe the necessary experimental design of the annotation ... -
MGMT Promoter Methylation Status Is Not Related to Histological or Radiological Features in IDH Wild-type Glioblastomas
(Peer reviewed; Journal article, 2020)O6-methylguanine DNA methyltransferase (MGMT) promoter methylation is an important favorable predictive marker in patients with glioblastoma (GBM). We hypothesized that MGMT status could be a surrogate marker of pretreatment ... -
MicroRNA as biomarkers in colorectal cancer
(Master thesis, 2016)Colorectal cancer (CRC) is one of the worlds leading causes of cancer-related deaths in both men and women. Nearly 1.4 million new cases were reported in 2012 and over half of the cases ended in death. High mortality rates ... -
microRNA-451a prevents activation of matrix metalloproteinases 2 and 9 in human cardiomyocytes during pathological stress stimulation.
(Peer reviewed; Journal article, 2019)Matrix metalloproteinases (MMP) are important for cardiac remodeling. Recently, microRNA (miR)-451a has been found to inhibit the expression of both MMP-2 and MMP-9 in human malignancies, but its role in cardiomyocytes has ... -
Microscale nuclear magnetic resonance gradient chip
(Peer reviewed; Journal article, 2022)We propose a design, micro fabrication process, and nuclear magnetic resonance (NMR) based evaluation, of a magnetic field gradient chip. The uni-axial linear z-gradient coil design was computed by a stream-function method, ... -
Midterm Outcomes for Endovascular Repair of Thoraco-Abdominal Aortic Aneurysms
(Journal article; Peer reviewed, 2022) -
Migraine and endothelial function: The HUNT3 Study.
(Journal article; Peer reviewed, 2016)Background: Reduced endothelial function is associated with elevated risk of cardiovascular disease, but evidence on the association between migraine and endothelial function is conflicting. The aim of this population-based ... -
Minimally invasive beat-by-beat monitoring of cardiac power in normal hearts and during acute ventricular dysfunction
(Journal article; Peer reviewed, 2016)Cardiac power, the product of aortic flow and blood pressure, appears to be a fundamental cardiovascular parameter. The simplified version named cardiac power output (CPO), calculated as the product of cardiac output (CO) ... -
Minor Myocardial Scars in Association with Cardiopulmonary Function after COVID-19
(Peer reviewed; Journal article, 2023)Background: Myocardial scars detected by cardiovascular magnetic resonance (CMR) imaging after COVID-19 have caused concerns regarding potential long-term cardiovascular consequences. Objective: The objective of this study ... -
miR-210 Regulates Apoptotic Cell Death during Cellular Hypoxia and Reoxygenation in a Diametrically Opposite Manner
(Peer reviewed; Journal article, 2021)Apoptotic cell death of cardiomyocytes is a characteristic hallmark of ischemia–reperfusion (I/R) injury. The master hypoxamiR, microRNA-210 (miR-210), is considered the primary driver of the cellular response to hypoxic ... -
Mitochondrial Function and Exercise in Cardiovascular Diseases
(Doctoral theses at NTNU;2019:221, Doctoral thesis, 2019)Kardiovaskulær sykdom er den vanligste dødsårsaken i verden, men epidemiologiske undersøkelser indikerer at trening kan redusere denne dødeligheten. Mekanismene bak den positive effekten av trening på kardiovaskulær helse ... -
Mitochondrial respiration after one session of calf raise exercise in patients with peripheral vascular disease and healthy older adults
(Journal article; Peer reviewed, 2016)Purpose: Mitochondria are essential for energy production in the muscle cell and for this they are dependent upon a sufficient supply of oxygen by the circulation. Exercise training has shown to be a potent stimulus for ... -
Mn-alginate gels as a novel system for controlled release of Mn2+ in manganese-enhanced MRI
(Journal article; Peer reviewed, 2012)The aim of the present study was to test alginate gels of different compositions as a system for controlled release of manganese ions (Mn2+) for application in manganese‐enhanced MRI (MEMRI), in order to circumvent the ... -
Model-Based Evaluation of Blood Velocity Estimation Techniques
(Doctoral thesis at NTNU;2015:81, Doctoral thesis, 2015)Pulsed Wave (PW) Doppler is a flow imaging modality in which the velocity distribution of the blood flow in a spatial region is displayed over time. In this work, methods for improvement of the conventional PW Doppler ... -
Modeling the diffusion-weighted imaging signal for breast lesions in the b = 200 to 3000 s/mm 2 range: quality of fit and classification accuracy for different representations
(Peer reviewed; Journal article, 2020)Purpose To evaluate different non‐Gaussian representations for the diffusion‐weighted imaging (DWI) signal in the b‐value range 200 to 3000 s/mm2 in benign and malignant breast lesions. Methods Forty‐three patients ... -
Modelling acoustic radiation from vibrating surfaces around coincidence: Radiation into fluids
(Peer reviewed; Journal article, 2023)It is well-known that vibrating surfaces generate sound waves in adjacent fluids. According to the classical radiation model, the nature of these waves depends on whether the vibration’s phase speed cv is above (supersonic) ... -
