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 ... -
Absent exercise-induced improvements in fat oxidation in women with polycystic ovary syndrome after high-intensity interval training
(Peer reviewed; Journal article, 2021)Background: Polycystic ovary syndrome (PCOS) and metabolic inflexibility are linked to insulin resistance, and women with PCOS appear to be metabolic inflexible in the rested, insulin-stimulated state. Exercise training ... -
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, ... -
Accuracy of electromagnetic tracking with a prototype field generator in an interventional OR setting
(Journal article; Peer reviewed, 2012)Purpose: The authors have studied the accuracy and robustness of a prototype electromagnetic window field generator (WFG) in an interventional radiology suite with a robotic C-arm. The overall purpose is the development ... -
Accuracy of heart rate watches: Implications for weight management
(Peer reviewed; Journal article, 2016)Background Wrist-worn monitors claim to provide accurate measures of heart rate and energy expenditure. People wishing to lose weight use these devices to monitor energy balance, however the accuracy of these devices ... -
Accuracy of Longitudinal Assessment of Visceral Adipose Tissue by Dual-Energy X-Ray Absorptiometry in Children with Obesity
(Peer reviewed; Journal article, 2019)Background. Increased visceral adipose tissue (VAT) is strongly associated with cardiometabolic risk factors. Accurate quantification of VAT is available through magnetic resonance imaging (MRI), which incurs a significant ... -
Acute and potentially persistent effects of scuba diving on the blood transcriptome of experienced divers
(Journal article; Peer reviewed, 2013)During scuba diving, the circulatory system is stressed by an elevated partial pressure of oxygen while the diver is submerged and by decompression-induced gas bubbles on ascent to the surface. This diving-induced stress ... -
Acute cardiac effects of exercise in the healthy and diseased
(Doctoral theses at NTNU;2023:344, Doctoral thesis, 2023)A growing trend in modern society is a polarization of the population into two distinct health groups. On the one hand, we see a steady increase in people who are health conscious and interested in exercise, while on the ... -
Acute Diffusion Tensor and Kurtosis Imaging and Outcome following Mild Traumatic Brain Injury
(Peer reviewed; Journal article, 2021)In this prospective cohort study, we investigated associations between acute diffusion tensor imaging (DTI) and diffusion kurtosis imaging (DKI) metrics and persistent post-concussion symptoms (PPCS) 3 months after mild ... -
Acute Effects of Different Types of Resistance Training on Cardiometabolic Health
(Master thesis, 2022)Bakgrunn: Til tross for at styrketrening er anerkjent som en effektiv strategi for å forebygge overvekt og kardiometabolsk sykdom, har vi fortsatt langt mer kunnskap om effekten av kondisjonstrening enn styrketrening på ... -
Acute effects of high intensity training on cardiac function: a pilot study comparing subjects with type 2 diabetes to healthy controls
(Peer reviewed; Journal article, 2022)This study evaluated acute cardiac stress after a high-intensity interval training session in patients with type 2 diabetes (T2D) versus healthy controls. High intensity aerobic exercise was performed by 4 × 4-min intervals ... -
Acute effects of strength and endurance training on bone turnover markers in young adults and elderly men
(Peer reviewed; Journal article, 2022)Context: Exercise is recognized as an important strategy to prevent bone loss, but its acute effects on bone turnover markers (BTMs) and related markers remain uncertain. Objective: To assess the acute effects of two ... -
Acute effects on the human peripheral blood transcriptome of decompression sickness secondary to scuba diving
(Peer reviewed; Journal article, 2021)Decompression sickness (DCS) develops due to inert gas bubble formation in bodily tissues and in the circulation, leading to a wide range of potentially serious clinical manifestations. Its pathophysiology remains incompletely ... -
Acute exercise is not cardioprotective and may induce apoptotic signalling in heart surgery: a randomized controlled trial
(Journal article; Peer reviewed, 2018)OBJECTIVES During open-heart surgery, the myocardium experiences ischaemia–reperfusion injury. A single bout of moderate, 30-min exercise induces preconditioning and protects the heart from ischaemia–reperfusion injury ... -
Acute exhaustive aerobic exercise training impair cardiomyocyte function and calcium handling in Sprague-Dawley rats
(Journal article; Peer reviewed, 2017)Introduction: Recent data from long-distance endurance participants suggest that cardiac function is impaired after completion. Existing data further indicate that right ventricular function is more affected than left ... -
Acute kidney injury in intensive care patients: Incidence, time course, and risk factors
