    • Exploring the roles of TRIM27 and TRIM32 in autophagy 

      Garcia Garcia, Juncal (Doctoral thesis; Doktorgradsavhandling, 2021-05-21)
      <p>Tripartite motif family proteins (TRIMs) are a wide family of E3 ligases involved in the control of several cellular processes such as intracellular signaling, innate immunity, transcription, cell cycle regulation and carcinogenesis. In recent years, some members of this family have been found to have a role in autophagy. <p>The central theme of this thesis is the role of two TRIM proteins in ...
    • Causes and Consequences of Gender Roles 

      Olsson, Maria (Doctoral thesis; Doktorgradsavhandling, 2021-05-03)
      This dissertation addresses the pervasive issue of women’s underrepresentation in agentic work and the equally important (but underexamined) issue of men’s underrepresentation in communal unpaid work. First, I review research and identify what conditions need to be met in order for counterstereotypical role models to break down some of the barriers to women’s entry into agentic work (Chapter 2). One ...
    • The role of ovarian reserve markers in fertility and fertility treatment 

      Bhide, Priya (Doctoral thesis; Doktorgradsavhandling, 2021-05-14)
      Ovarian reserve is a key component influencing reproductive function and fertility. Serum anti-Mullerian hormone (AMH) and antral follicle count (AFC) are established quantitative markers of ovarian reserve. The overall aim of this thesis comprising four work packages was to study the role of AMH and AFC on different aspects of fertility and fertility treatment. Their specific objectives were: 1) To ...
    • The development journey of an artificial intestinal model predicting oral drug absorption: the mucus-PVPA model 

      Falavigna, Margherita (Doctoral thesis; Doktorgradsavhandling, 2021-04-23)
      Oral drug administration is the most convenient route to systemically deliver drugs because of its cost-effectiveness, ease of administration and high patient compliance. However, when a drug is orally administered it will be exposed to the different physiological processes and environments found along the gastrointestinal (GI) tract, which will determine its ability of being absorbed and reach the ...
    • We Ran a Hospital. The Norwegian Nurses efforts During the Korean War and the Impact of their Experiences on Norwegian Nursing and Theatre Nursing 

      Lockertsen, Jan-Thore (Doctoral thesis; Doktorgradsavhandling, 2021-04-23)
      <p>During the Korean War (1951-53), Norway operated and staffed a surgical field hospital at the front along the 38th parallel. The Norwegian Mobile Army Surgical Hospital – NORMASH – was a part of the United Nations peace-enforcing force to stop aggression from North-Korea towards South-Korea. <p>NORMASH was staffed only with civilian volunteers. Without any training as a military group or in war ...
    • Studies of sleep and seasonal variations in patients with chronic musculoskeletal pain 

      Abeler, Karin (Doctoral thesis; Doktorgradsavhandling, 2021-04-19)
      <p><i>Background/aims:</i> Chronic pain is a major health problem, and contributing factors include poor sleep and mental distress. In the subarctic city of Tromsø, clinical impression also suggests worse pain in winter. We aimed to examine whether sleep in patients with chronic musculoskeletal pain differs from pain-free controls, and how psychological processes are related to sleep in these groups. ...
    • Metacognition and decision-making in schizophrenia: Exploring how aberrant processing and representation of uncertainty may explain cognitive-behavioral biases 

      Kreis, Isabel Viola (Doctoral thesis; Doktorgradsavhandling, 2021-04-13)
      The cognitive profile associated with schizophrenia has long been a research subject of interest. A plethora of studies have not only revealed cognitive deficits but also cognitive biases, meaning qualitative deviations in the way information is processed and evaluated. Such biases are for example reflected in findings of diminished metacognitive accuracy, or premature and disadvantageous decision-making. ...
    • Biomarkers of major bleeding after incident venous thromboembolism 

      Johnsen, Håkon Sandbukt (Doctoral thesis; Doktorgradsavhandling, 2021-03-23)
      Major bleeding (MB) events are feared and potentially fatal complications of anticoagulant treatment in patients with venous thromboembolism (VTE). Even though several clinical risk factors are associated with MB risk, the predictive power of currently available risk assessment models remain limited for VTE. The aim of this thesis was to identify biomarkers of MB risk during the first year after an ...
    • A biomarker approach to explain high cardiovascular disease burden in Russia: insights from population-based studies in Russia and Norway 

      Iakunchykova, Olena (Doctoral thesis; Doktorgradsavhandling, 2021-03-25)
      Although the problem of cardiovascular disease (CVD) in Russia has been the subject of attention for decades, a definitive and comprehensive explanation of why the CVD burden there is so high and generally greater than in many other countries has still not been found. In this thesis, I have attempted to advance research on these issues by examining the role of blood lipids, heart damage biomarkers ...
    • mHealth: opportunities and challenges for diabetes intervention research 

      Bradway, Meghan (Doctoral thesis; Doktorgradsavhandling, 2021-03-12)
      <p><i>Background:</i> Traditionally, health intervention evaluations provide long-term evidence of efficacy and safety via validated protocols, following a positivist paradigm, or approach, to research. However, modern mobile health (mHealth) technologies develop too quickly and outside of medical regulation, making it challenging for health research to keep pace. <p><i>Objective:</i> This thesis ...

      The present thesis has investigated the cross-sectional and prospective associations between self-reported and objectively measured physical activity with five objectively measured indices of body composition in Norwegian adolescents participating in the Tromsø Study Fit: Futures Cohort. The three included papers used regression analyses to assess the cross-sectional association between self-reported ...
    • Unraveling nanoscale alterations in liver cell fenestrations - Morphological studies via optical super-resolution microscopy approaches 

      Mao, Hong (Doctoral thesis; Doktorgradsavhandling, 2021-01-22)
      The endothelium makes up the innermost cell layer of blood vessels. It consists of a thin layer of simple squamous cells, forming an interface between circulating blood and the surrounding tissue. Endothelial cells of different vascular beds are specialized according to tissue-specific functions. For this project emphasis was placed upon high-resolution methods enabling the study of liver sinusoidal ...
    • Bacterial Extracellular vesicles and their cargo 

      Joshi, Bishnu (Doctoral thesis; Doktorgradsavhandling, 2021-02-05)
      <i>Staphylococcus aureus</i> and <i>Enterococcus faecium</i> are opportunistic pathogens that may cause diseases ranging from minor skin infection to severe blood stream infections. The emergence of methicillin-resistant <i>Staphylococcus aureus</i> (MRSA) and vancomycin-resistant enterococcal strains severely limits treatment options. Bacteria release extracellular vesicles (EVs), defined as ...
    • Human platelet antigen (HPA)-1a alloimmunization - Why only blame it on the platelets? 

      Heide, Gøril (Doctoral thesis; Doktorgradsavhandling, 2021-01-15)
      Antibodies against human platelet antigen (HPA)-1a are the most common cause of fetal and neonatal alloimmune thrombocytopenia (FNAIT) in Caucasians, and is a break of the tolerance normally seen for the fetus in pregnant women. The initiation of immunization is suggested to be feto-maternal transfer of platelets during pregnancy and at delivery, and one of the consequences of anti-HPA-1a antibodies ...
    • Acute intermittent porphyria. Inflammation, diet and biomarkers in acute intermittent porphyria 

      Storjord, Elin (Doctoral thesis; Doktorgradsavhandling, 2021-01-22)
      Acute intermittent porphyria (AIP) is a rare autosomal dominant inherited metabolic disease with lowered function of the enzyme hydroxymethylbilan synthase due to mutation in this gene of the heme synthesis. The resulting excess of aminolevulinic acid and porphobilinogen can result in acute abdominal pain, paresis, fatigue, increased risk for kidney failure and hepatocellular carcinoma. Some drugs, ...
