Low-grade impairments in cognitive and kidney function in a healthy middle-aged general population: a cross-sectional study
(Master thesis; Mastergradsoppgave, 2019-10-28)Background: Although the relationship between manifest chronic kidney disease and reduced cognitive function is well established, limited data exists on GFR and cognitive function in the general population. Both the brain and kidneys have low-impedance vascular beds, rendering them susceptible to damage from pulsatile blood flow. An association between mildly reduced GFR and cognitive function in ... -
Mapping of Nuclear Export Signals and domains mediating aggregation of NBR1
(Master thesis; Mastergradsoppgave, 2017-11-02)Autophagy is a conserved catabolic pathway for the lysosomal degradation of cytoplasmic components. Autophagy can be both selective and unselective. Selective autophagy receptor proteins are involved in mediating the degradation of specific substrates. Among these receptors we find the evolutionary related proteins p62 and NBR1, which are both involved in autophagic degradation of different ubiquitinated ... -
Outcome of aneurysmal subarachnoid hemorrhage in a population-based cohort: Retrospective registry study
(Master thesis; Mastergradsoppgave, 2023-10-31)Background: Studies of aneurysmal subarachnoid hemorrhage (aSAH) report an association between higher patient volumes and better outcomes. In regions with dispersed settlement, this must be balanced against the advantages with shorter pre-hospital transport times and timely access. The aim of this study is to report outcome for unselected aSAH-cases from a well-defined rural population treated in a ... -
Overexpression of miR-20a-5p in Tumor Epithelium Is an Independent Negative Prognostic Indicator in Prostate Cancer — A Multi-Institutional Study
(Master thesis; Mastergradsoppgave; Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-26)<p><i>Background:</i> MicroRNAs (miRs) have critical regulatory roles in cell functions, and are involved in prostate cancer tumorigenesis. miR-20a-5p is a member of the oncogenic miR-17-92 cluster. Overexpressed miR-20a-5p has been shown to increase both cell proliferation and cell migration in cancers. The aim of our cohort study was to evaluate the prognostic role of miR-20a-5p in prostate cancer. ... -
Performance and clinical applicability of machine learning in liver computed tomography imaging: a systematic review
(Master thesis; Mastergradsoppgave, 2023-09-12)Abstract Objectives: Machine learning (ML) for medical imaging is emerging for several organs and image modalities. Our objectives were to provide clinicians with an overview of this field by answering the following questions: (1) How is ML applied in liver computed tomography (CT) imaging? (2) How well do ML systems perform in liver CT imaging? (3) What are the clinical applications of ML in liver ... -
Possible origin of a vanB-type Enterococcus faecium causing a multicentre outbreak in Sweden
(Master thesis; Mastergradsoppgave, 2013-11-01)Dissemination of vancomycin-resistant Enterococcus faecium (VREfm) with similar pulsed-field gel electrophoresis patterns in three Swedish hospitals between 2007 and 2011 prompted molecular characterization to reveal the possible origins and features of the strain. A representative subset of collected isolates (VREfm (n=18) and vancomycin-susceptible Enterococcus faecium (VSEfm) (n=2)) reflecting ... -
Pre-test characteristics of unstable angina patients with obstructive coronary artery disease confirmed by coronary angiography
(Master thesis; Mastergradsoppgave, 2017-10-31)Objective As the mortality and rate of obstructive coronary artery disease (CAD) is low in patients with unstable angina (UA), better pre-test selection criteria for acute coronary angiography (CAG) is warranted. We aimed to validate the current guidelines against other clinical variables as predictors of obstructive CAD in UA patients referred for acute CAG. Methods From 2005 to 2012, all CAGs ... -
Presence of high-endothelial venules correlates with a favorable immune microenvironment in oral squamous cell carsinoma
(Master thesis; Mastergradsoppgave, 2017-10-31)Oral squamous cell carcinomas (OSCC) are associated with a poor prognosis, which may be partly due to functional impairment of the immune response. Lymphocyte recruitment to the tumor site is facilitated by high-endothelial venules (HEV), whereas expression of programmed-death ligand 1 (PD-L1) can impair T cell function. Thus, we hypothesize that these factors are important in shaping the immune ... -
Prognostic impact of CXCL16 and CXCR6 in non-small cell lung cancer: combined high CXCL16 expression in tumor stroma and cancer cells yields improved survival
(Master thesis; Mastergradsoppgave, 2015-10-27)BACKGROUND: The chemokine CXCL16 and its receptor CXCR6 are expressed by a variety of immune cells and have been shown to influence angiogenesis. The expression of CXCR6 and CXCL16 has been examined in numerous human cancers; however no studies have yet investigated their influence on prognosis in non-small cell lung cancer (NSCLC). We aimed to explore their prognostic significance in NSCLC, in ... -
Recombinant T-cell receptors from HPA-1a specific T-cells
(Mastergradsoppgave; Master thesis, 2022-02-01)Fetal- and neonatal alloimmune thrombocytopenia is a condition that can cause hemorrhage and potential brain damage or death in neonates. It is most often a result of maternal alloantibodies specific for fetal Human Platelet antigen 1a (HPA-1a) that destroy fetal platelets. The recognition of the HPA-1a peptide-MHC complex by T-cells involve a peculiar form of T-cell receptor peptide-MHC ... -
Serum free and bio-available 25-hydroxyvitamin D correlate better with bone density than serum total 25-hydroxyvitamin D
(Master thesis; Mastergradsoppgave, 2015-10-29)Introduction/background In the circulation 25-hydroxyvitamin D (25(OH)D) is bound to vitamin D-binding protein (DBP) and albumin. Only a small fraction is in the unbound, free form. According to the ‘free-hormone-hypothesis’ only the free form is biologically active. Genetic differences in DBP may affect the binding to 25(OH)D and thereby the amount of free 25(OH)D. Methods In the present study ... -
Treatment of Cardiovascular Dysfunction With PDE5-Inhibitors – Temperature Dependent Effects on Transport and Metabolism of cAMP and cGMP
(Master thesis; Mastergradsoppgave, 2023-10-21)Introduction: Cardiovascular dysfunction is a potentially lethal complication of hypothermia. Due to a knowledge gap, pharmacological interventions are not recommended at core temperatures below 30°C. Yet, further cooling is induced in surgical procedures and survival of accidental hypothermia is reported after rewarming from below 15°C, advocating a need for evidence-based treatment guidelines. In ... -
Trends in prevalence of ultrasound-assessed carotid atherosclerosis in a general population over time. The Tromsø Study 1994-2016
(Master thesis; Mastergradsoppgave, 2021-11-11)<p><i>Background:</i> During the past decades, there has been a shift in risk factor levels in many high-income countries, with decrease in smoking, blood pressure and cholesterol levels, while body mass index, obesity and diabetes increase. The diverging trends may have opposite effects on prevalence of atherosclerosis. We aimed to assess carotid plaque prevalence and the association with risk ...
