    • The creation of long-lived HPA-1a specific T-cell clones 

      Roalsø, Marcus T.T. (Master thesis; Mastergradsoppgave, 2016-08-09)
      Neonatal alloimmune thrombocytopenia (NAIT) is a disease where the fetus or newborn experience pathological low levels of blood platelets. This is a potentially fatal condition. Antibodies produced by the mother, crossing the placental barrier, targeting the β3-integrins expressed on fetal platelets, drive the disease. The antibodies are initially produced by B-cells, which are dependent on T-cells ...
    • Early fulminant BK polyomavirus-associated nephropathy in two kidney transplant patients with low neutralizing antibody titers receiving allografts from the same donor 

      Lorentzen, Elias Myrvoll; Henriksen, Stian; Kaur, Amandeep; Kro, Grete Birkeland; Hammarström, Clara; Hirsch, Hans H; Midtvedt, Karsten; Rinaldo, Christine Hanssen (Journal article; Tidsskriftartikkel; Peer reviewed; Mastergradsoppgave; Master thesis, 2020-01-10)
      <i>Background</i> - BK Polyomavirus (BKPyV) causes premature graft failure in 1 to 15% of kidney transplant (KT) recipients. High-level BKPyV-viruria and BKPyV-DNAemia precede polyomavirus-associated nephropathy (PyVAN), and guide clinical management decisions. In most cases, BKPyV appears to come from the donor kidney, but data from biopsy-proven PyVAN cases are lacking. Here, we report the early ...
    • EEG-based effective connectivity distinguishes between unresponsive states with and without report of conscious experience and correlates with brain complexity 

      Bremnes, Thomas René; Juel, B.E.; Gosseries, O.; Rosanova, M.; Boly, M.; Laureys, S.; Larsson, P.G.; Massimini, M.; Storm, Johan Frederik (Master thesis; Mastergradsoppgave, 2017-11-01)
      Objective methods for distinguishing conscious from unconscious states in humans are of key importance for clinical evaluation of general anesthesia and patients with disorders or consciousness. Here, we test the generalizability of a DTF-based algorithm - a measure of effective connectivity - as an objective measure of conscious experience during anesthesia and correlate it with a well-tested index ...

      Purpose: Type 2 diabetes mellitus is associated with increased fracture risk and recent studies show crosstalk between bone and glucose metabolism. Few studies have investigated the effect of vitamin D supplementation on bone without additional calcium. In the present study, we aimed to determine whether a high dose of vitamin D3 could improve bone mass density (BMD) in prediabetic subjects. Methods: ...
    • The effect of one-hour hypothermia on long term spatial memory in male Long Evans rats 

      Marsteen, Håvar (Master thesis; Mastergradsoppgave, 2020-11-01)
      The human body is willing to expend great amount of energy on mechanisms that keep the core temperature within a very small range. When these mechanisms are overwhelmed the body temperature either rises (hyperthermia) or drops (hypothermia). Hypothermia has earlier been used to induce retrograde amnesia (forgetting) and we have in this study examined if hypothermia can affect a robust long-term ...
    • Estrogen receptors α and β and aromatase as independent predictors for prostate cancer outcome 

      Grindstad, Thea Karoline Walstad (Master thesis; Mastergradsoppgave, 2016-10-11)
      Androgens are considered important in normal prostate physiology and prostate cancer (PCa) pathogenesis. However, androgen-targeted treatment preventing PCa recurrence is still lacking. This indicates additional mediators contributing to cancer development. We sought to determine the prognostic significance of estrogen receptors, ERα and -β, and the aromatase enzyme in PCa. Tissue microarrays ...

    • Fibrinogen gamma gene rs2066865 and risk of cancer-related venous thromboembolism 

      Paulsen, Benedikte (Master thesis; Mastergradsoppgave, 2019-10-31)
      Venous thromboembolism is a frequent complication in patients with cancer. Homozygous carriers of the fibrinogen gamma gene (FGG) rs2066865 have a moderately increased risk of venous thromboembolism, but the effect of the FGG variant in cancer is unknown. We aimed to investigate the effect of the FGG variant and active cancer on the risk of venous thromboembolism. Cases with incident venous ...
    • Gender differences in hearts subjected to decreased NO-production and elevated blood pressure 

      Kildal, Simon; Ludvigsen, Stian; Norvik, Jon Viljar; Johansen, David; Ytrehus, Kirsti (Master thesis; Mastergradsoppgave, 2016-10-31)
      Hypertension is one of the most important risk factors for heart failure in the general population. Hypertensive heart failure is associated with heart failure with preserved ejection fraction (HFpEF). Women have an increase proportion of HFpEF compared to men. Endothelial dysfunction thereby reduced NO production is proposed to play an important role in the pathophysiology of HFpEF. A suggested ...
    • Hepatic steatosis detected by ultrasonography as a predictor of insulin resistance in obese patients 

      Isaksen, Victoria Therese (Master thesis; Mastergradsoppgave, 2014-10-31)
      Non-alcoholic fatty liver disease is closely related to the Metabolic syndrome. A significant feature of NAFLD is the presence of hepatic steatosis, which can be assessed by ultrasonography, by measuring the hepatorenal index (HRI), a comparison of liver and kidney acoustic echo densities. This study aims to investigate if HRI can predict insulin resistance. Ninety participants from the obesity ...

Objectives: To examine the association between hyperglycemia, assessed by HbA1c, and future risk of VTE in a population based cohort. Methods: HbA1c was measured in 16 156 unique subjects (25-87 years) ...
    • Impact of incident venous thromboembolism on risk of arterial thrombotic diseases 

      Lind, Caroline (Master thesis; Mastergradsoppgave, 2015-10-26)
      Background: Growing evidence support an association between venous thromboembolism (VTE) and arterial thrombotic diseases (i.e. myocardial infarction (MI) and ischemic stroke). We aimed to study the association between VTE and future arterial events, and to determine the population attributable risk (PAR%) of arterial events by VTE in a large prospective cohort recruited from the general ...
    • Ischemic stroke and risk of venous thromboembolism in the general population. The Tromsø study 

      Rinde, Ludvig Balteskard (Master thesis; Mastergradsoppgave, 2017-10-21)
      Background: Even though clinical data support a relation between ischemic stroke and venous thromboembolism (VTE), the strength and time dependence of the association remain to be settled at the population level. We therefore aimed to investigate the association between ischemic stroke and VTE in a prospective population-based cohort. Methods and Results: Participants (n=30 002) were recruited from ...
    • Low-grade impairments in cognitive and kidney function in a healthy middle-aged general population: a cross-sectional study 

      Småbrekke, Silje; Schirmer, Henrik; Melsom, Toralf; Solbu, Marit Dahl; Eriksen, Bjørn Odvar (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 

      Næss, Morten Svendsen (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 

      Iversen, Mathilde Vea (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 ...
