Atrial fibrillation and exercise
(Doctoral theses at NTNU;2019:60, Doctoral thesis, 2019)Atrial fibrillation (AF) is the most common persistent arrhythmia, with a prevalence of 2-3% in the adult population and is associated with an increased morbidity and mortality. This is caused by an increased risk of stroke ... -
Atrial Myocyte Function and Ca2+ Handling Is Associated with Inborn Aerobic Capacity
(Peer reviewed; Journal article, 2013-10-16)Background: Although high aerobic capacity is associated with effective cardiac function, the effect of aerobic capacity on atrial function, especially in terms of cellular mechanisms, is not known. We aimed to investigate ... -
Atrial myocyte structure, function and calcium handling in cardiac disease: Effects of maximal oxygen uptake
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:105, Doctoral thesis, 2014)Atrial function, through its refilling of the ventricles, plays an important role in cardiac performance. The atrial contribution is particularly important during periods of high heart rates, such as during exercise or ... -

Atypical brain structure mediates reduced IQ in young adults born preterm with very low birth weight
(Peer reviewed; Journal article, 2022)Preterm birth with very low birth weight (VLBW) confers heightened risk for perinatal brain injury and long-term cognitive deficits, including a reduction in IQ of up to one standard deviation. Persisting gray and white ... -
Augmenting drug-carrier compatibility improves tumour nanotherapy efficacy
(Journal article; Peer reviewed, 2016)A major goal of cancer nanotherapy is to use nanoparticles as carriers for targeted delivery of anti-tumour agents. The drug–carrier association after intravenous administration is essential for efficient drug delivery to ... -
Autocrine activin A signalling in ovarian cancer cells regulates secretion of interleukin 6, autophagy, and cachexia
(Journal article; Peer reviewed, 2019)Background The majority of patients with advanced cancer develop cachexia, a weight loss syndrome that severely reduces quality of life and limits survival. Our understanding of the underlying mechanisms that cause the ... -
Automated 2-D and 3-D Left Atrial Volume Measurements Using Deep Learning
(Journal article; Peer reviewed, 2023)Objective: Echocardiography, a critical tool for assessing left atrial (LA) volume, often relies on manual or semi-automated measurements. This study introduces a fully automated, real-time method for measuring LA volume ... -
Automated blood glucose control: Development and Testing of an Artificial Endocrine Pancreas Using a Novel Intravascular Glucose Monitor and a New Approach to Insulin Pharmacology
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:275, Doctoral thesis, 2012)This thesis describes the stepwise development and testing of the components of a novel artificial endocrine pancreas, consisting of a continuous glucose monitor, an insulin infusion device and a control algorithm. The ... -
Automated estimation of mitral annular plane systolic excursion by artificial intelligence from 3D ultrasound recordings
(Peer reviewed; Journal article, 2023)Perioperative monitoring of cardiac function is beneficial for early detection of cardiovascular complications. The standard of care for cardiac monitoring performed by trained cardiologists and anesthesiologists involves ... -
Automated Patient-level Prostate Cancer Detection with Quantitative Diffusion Magnetic Resonance Imaging
(Peer reviewed; Journal article, 2023)Background Multiparametric magnetic resonance imaging (mpMRI) improves detection of clinically significant prostate cancer (csPCa), but the subjective Prostate Imaging Reporting and Data System (PI-RADS) system and ... -
Automated reference tissue normalization of T2-weighted MR images of the prostate using object recognition
(Peer reviewed; Journal article, 2020)Objectives To develop and evaluate an automated method for prostate T2-weighted (T2W) image normalization using dual-reference (fat and muscle) tissue. Materials and methods Transverse T2W images from the publicly ... -
Automatic analysis in echocardiography using machine learning
(Doctoral theses at NTNU, 2021:230, Doctoral thesis, 2021)Echocardiography is the cornerstone of modern cardiac imaging due to its availability, low cost and real-time functionality. The modality has enabled sophisticated non-invasive evaluation of the hearts morphophysiology, ... -
Automatic assessment of left ventricular function for hemodynamic monitoring using artificial intelligence and transesophageal echocardiography
(Peer reviewed; Journal article, 2024)We have developed a method to automatically assess LV function by measuring mitral annular plane systolic excursion (MAPSE) using artificial intelligence and transesophageal echocardiography (autoMAPSE). Our aim was to ... -
