(Peer reviewed; Journal article, 2021)This study examines the feasibility of blood speckle tracking for vector flow imaging in healthy adults and describes the physiologic flow pattern and vortex formation in relation to the wall motion in the left ventricle. ... -
INTRAVENØS ERNÆRING TIL PASIENTER MED UHELBREDELIG KREFT- EN RETROSPEKTIV STUDIE AV KLINISK PRAKSIS VED SYKEHUSET I VESTFOLD
(Master thesis, 2023)Sammendrag Bakgrunn: Intravenøs ernæring til pasienter med uhelbredelig kreft er forsket lite på. Det er lite systematisk og evidensbasert kunnskap, samt upresise retningslinjer for hvem vi skal gi det til, hvordan det ... -
Intravenøs optimalisering av kontrast ved CT-angiografi
(Bachelor thesis, 2020)SAMMENDRAG Introduksjon: CT-angiografi med kontrastinjeksjon kan gi en god fremstilling av kroppens blodårer. Til tross for at CT har mange fordeler som tilknyttet bildediagnostikk, har denne avbildningsteknikken også ... -
Intra‐arterial blood pressure traits during and after heavy resistance exercise in healthy males
(Journal article; Peer reviewed, 2019)This randomized within‐subjects crossover‐designed study evaluated intra‐arterial blood pressure (BP) traits in seven healthy males (24 ± 1 years) during heavy resistance exercise (HRE) to failure (10 × 5 repetitions, 5RES) ... -
The introduction of a regional Norwegian HEMS coordinator: an assessment of the effects on response times, geographical service areas and severity scores
(Peer reviewed; Journal article, 2022)Background Due to unwanted delays and suboptimal resource control of helicopter emergency medical services (HEMS), regional HEMS coordinators have recently been introduced in Norway. This may represent an unnecessary ... -
Investigating the causal interplay between sleep traits and risk of acute myocardial infarction: a Mendelian randomization study
(Peer reviewed; Journal article, 2023)Background Few studies have investigated the joint effects of sleep traits on the risk of acute myocardial infarction (AMI). No previous study has used factorial Mendelian randomization (MR) which may reduce confounding, ... -
Investigation of cellular and structural basis of cardiac arrhythmias using two-photon microscopy
(Doctoral theses at NTNU;2020:165, Doctoral thesis, 2020)Cardiovascular diseases are often associated with arrhythmias, an electrical dysfunction in which the normal heart rhythm is disturbed. Arrhythmias are multifactorial phenomena, and understanding the mechanisms underlying ... -
Investigation of Differences in Appetite-Related Hormones and Subjective Feelings of Appetite Between Patients with Suboptimal and Optimal Weight Loss Ten Years After Roux-en-Y Gastric Bypass Surgery
(Master thesis, 2020)Sammendrag (norsk) Undersøkelse av forskjeller i appetittrelaterte hormoner og subjektiv appetitt opplevelse mellom pasienter med suboptimal og optimal vektnedgang 10 år etter Roux-en-Y Gastrisk Bypass kirurgi Introduksjon: ... -
Investigation of the role of carbohydrate intake on gut microbiota and short-chain fatty acids
(Master thesis, 2021)Bakgrunn: Ketogene dietter har stadig økt i popularitet de siste årene, antakelig fordi de har vist at de kan føre til vekttap, samtidig som de forebygger en økning i appetitt som vanligvis forekommer ved vektreduksjon. ... -
Iodinated contrast media and their effect on thyroid function – Routines and practices among diagnostic imaging departments in Norway
(Peer reviewed; Journal article, 2020)Introduction In order to minimise adverse effects or patient injuries related to the effect of iodinated contrast media (ICM) on the thyroid, international guidelines and research recommend developing routines for ... -

Is APIM functional in RAD5 homolog HLTF?
(Master thesis, 2016)To ensure secure transmission of genome to daughter cells, all cells carry out highly processive error-free replication of the genome. Proliferating cell nuclear antigen (PCNA) plays a central part as processivity factor ... -
Is dietary nitrate supplementation necessary to ensure proper endothelial function at altitude?
(Master thesis, 2014)Introduction: At altitude the body is exposed to systemic hypobaric hypoxia and adapts in order to optimize oxygen delivery to the tissue. Maintaining peripheral vascular function is essential in this process, tightly ... -
Is the anatomical distribution of low-grade gliomas linked to regions of gliogenesis?
(Peer reviewed; Journal article, 2020)Introduction According to the stem cell theory, two neurogenic niches in the adult human brain may harbor cells that initiate the formation of gliomas: The larger subventricular zone (SVZ) and the subgranular zone (SGZ) ... -
