(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) ... -
Models and Methods for Investigation of Reverberations in Nonlinear Ultrasound Imaging
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:217, Doctoral thesis, 2011)Models and methods for investigation of reverberations in nonlinear imaging techniques are presented in this thesis. Four independent papers provide insight on nonlinear propagation effects, a theoretical description of ... -
Moderate and severe traumatic brain injury in general hospitals: a ten-year population-based retrospective cohort study in central Norway
(Peer reviewed; Journal article, 2022)Background Patients with moderate and severe traumatic brain injury (TBI) are admitted to general hospitals (GHs) without neurosurgical services, but few studies have addressed the management of these patients. This ... -
Moderate continuous or high intensity interval exercise in heart failure with reduced ejection fraction: Differences between ischemic and non-ischemic etiology
(Peer reviewed; Journal article, 2022)Background Exercise for heart failure (HF) with reduced ejection fraction (HFrEF) is recommended by guidelines, but exercise mode and intensities are not differentiated between HF etiologies. We, therefore, investigated ... -
Moderate traumatic brain injury, acute phase course and deviations in physiological variables: an observational study
(Journal article; Peer reviewed, 2016)Background: Patients with moderate traumatic brain injury (TBI) are a heterogeneous group with great variability in clinical course. Guidelines for monitoring and level of care in the acute phase are lacking. The main ... -
Molecular and functional characterization of breast cancer through a combination of MR imaging, transcriptomics and metabolomics
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:14, Doctoral thesis, 2012)Breast cancer is the most frequent cancer among women in Norway. The outcome of this disease is heterogeneous. Some patients have slowly growing tumors which stay confined within the mammary gland, whereas others have ... -
Monitoring quality of care for peripheral intravenous catheters; feasibility and reliability of the peripheral intravenous catheters mini questionnaire (PIVC-miniQ)
(Journal article; Peer reviewed, 2019)Background Peripheral intravenous catheters (PIVCs) account for a mean of 38% of catheter associated bloodstream infections (CABSI) with Staphylococcus aureus, which are preventable if deficiencies in best practice are ... -
Monitoring variability in parameter estimates for lumped parameter models of the systemic circulation using longitudinal hemodynamic measurements
(Journal article; Peer reviewed, 2023)Background Physics-based cardiovascular models are only recently being considered for disease diagnosis or prognosis in clinical settings. These models depend on parameters representing the physical and physiological ... -
