Aerobic exercise training rescues cardiac protein quality control and blunts endoplasmic reticulum stress in heart failure rats
(Peer reviewed; Journal article, 2016)Cardiac endoplasmic reticulum (ER) stress through accumulation of misfolded proteins plays a pivotal role in cardiovascular diseases. In an attempt to reestablish ER homoeostasis, the unfolded protein response (UPR) is ... -
Aerobic high intensity interval training is an effective treatment for patients with Chronic Obstructive Pulmonary Disease
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:194, Doctoral thesis, 2009)Aerobic high intensity interval cycling at 85-95% of peak heart rate improves peak oxygen uptake (VO2peak) and performance in severe chronic obstructive pulmonary disease patients (COPD). One leg cycling demonstrates greater ... -
Aerobic High-Intensity Interval Training Improve VO2max More Than Sprint Interval Training
(Master thesis, 2020)Purpose: To compare the effects of sprint interval training (SIT) and high-intensity interval training (HIIT) on endurance performance and endurance performance determinants. Methods: Twenty-three healthy, trained female ... -
Aerobic high-intensity intervals improve V̇O2max more than supramaximal sprint intervals in females, similar to males
(Journal article; Peer reviewed, 2023)Introduction: Maximal oxygen uptake (V̇O2max) is a pivotal factor for aerobic endurance performance. Recently, aerobic high-intensity interval training (HIIT) was documented to be superior to sprint interval training (SIT) ... -
Aerobic interval training partly reverse contractile dysfunction and impaired Ca2+ handling in atrial myocytes from rats with post infarction heart failure
(Journal article; Peer reviewed, 2013)Background: There is limited knowledge about atrial myocyte Ca2+ handling in the failing hearts. The aim of this study was to examine atrial myocyte contractile function and Ca2+ handling in rats with post-infarction heart ... -
Aerobic Interval Training Prevents Age-Dependent Vulnerability to Atrial Fibrillation in Rodents
(Journal article; Peer reviewed, 2018)Aims: Increasing age is the most important risk factor for atrial fibrillation (AF). Very high doses of exercise training might increase AF risk, while moderate levels seem to be protective. This study aimed to examine the ... -
Age, weight and decompression sickness in rats
(Journal article; Peer reviewed, 2016)Objective: The aim of this study was to determine if, after controlling for weight, age is associated with decompression sickness (DCS) in rats. Methods: Following compression-decompression, male rats aged 11 weeks were ... -
Age-related change in peak oxygen uptake and change of cardiovascular risk factors. The HUNT Study
(Peer reviewed; Journal article, 2020)Background Large longitudinal studies on change in directly measured peak oxygen uptake (VO2peak) is lacking, and its significance for change of cardiovascular risk factors is uncertain. We aimed to assess ten-year ... -
Age-related decline in peak oxygen uptake: Cross-sectional vs. longitudinal findings. A review
(Peer reviewed; Journal article, 2023)Cardiorespiratory fitness is established as an important prognostic factor for cardiovascular and general health. In clinical settings cardiorespiratory fitness is often measured by cardiopulmonary exercise testing determining ... -
AI Risk Score on Screening Mammograms Preceding Breast Cancer Diagnosis
(Peer reviewed; Journal article, 2023)Background Few studies have evaluated the role of artificial intelligence (AI) in prior screening mammography. Purpose To examine AI risk scores assigned to screening mammography in women who were later diagnosed ... -
AI-driven attenuation correction for brain PET/MRI: Clinical evaluation of a dementia cohort and importance of the training group size
(Peer reviewed; Journal article, 2020)Introduction Robust and reliable attenuation correction (AC) is a prerequisite for accurate quantification of activity concentration. In combined PET/MRI, AC is challenged by the lack of bone signal in the MRI from which ... -
Airway segmentation and centerline extraction from thoracic CT - Comparison of a new method to state of the art commercialized methods
(Peer reviewed; Journal article, 2015)Introduction Our motivation is increased bronchoscopic diagnostic yield and optimized preparation, for navigated bronchoscopy. In navigated bronchoscopy, virtual 3D airway visualization is often used to guide a bronchoscopic ... -
Akutt abdomen ved en observasjonsenhet
(Master thesis, 2016)Målet med denne retrospektive studien er å beskrive pasientpopulasjonen som innlegges med akutte magesmerter ved en observasjonsenhet ved et norsk universitetssykehus. Oppgaven tar for seg hvordan pasientene utredes og ... -
Akutt lungesviktsyndrom hos covid-19-pasient med negative nasofarynksprøver
(Peer reviewed; Journal article, 2020)En kvinne i 40-årene som ble innlagt etter tre ukers sykehistorie med luftveisinfeksjon, utviklet alvorlig akutt lungesviktsyndrom. Nasofarynksprøver tatt dag 1 og 3 etter innleggelse var negative for sars-CoV-2-viruset, ... -
Aligning peripheral intravenous catheter quality with nursing culture—A mixed method study
(Journal article; Peer reviewed, 2024)Aim: To explore barriers and facilitators that influence adherence to evidence-based guidelines for peripheral intravenous catheter care in different hospital wards. Design: Sequential explanatory mixedmethod study design, ... -
Allocentric representation in the human amygdala and ventral visual stream
(Peer reviewed; Journal article, 2021)The hippocampus and the entorhinal cortex are considered the main brain structures for allocentric representation of the external environment. Here, we show that the amygdala and the ventral visual stream are involved in ... -
