      Ramberg, Cathrine (Doctoral thesis; Doktorgradsavhandling, 2021-11-05)
      Venous thromboembolism (VTE) is the formation of a blood clot in, most commonly, the deep veins of the lower extremities and the pulmonary circulation. VTE is a prevalent disease associated with severe short- and long-term complications. Negatively charged procoagulant phospholipids (PPL), and phosphatidylserine (PS) in particular, are vital to efficient coagulation activation, and found expressed ...

    • The role of the estrogen receptor α in the medial amygdala and the ventromedial nucleus of the hypothalamus in sexual motivation, social recognition, aggression and anxiety 

      Spiteri, Thierry (Doctoral thesis; Doktorgradsavhandling, 2010-09-01)
      Estrogens have been shown to be implicated not only in sexual behaviors but also in several cognitive functions, social behaviors, and emotional reactions. Estrogen receptors mediate estrogen actions in the brain and the estrogen receptor α (ERα) has attracted some attention. Although the display of female sexual motivation and copulatory behaviors require estrogens, their sites of action in brain ...

    • Safety of Treatment Provided by Homeopaths Homeopathic Aggravations, Adverse Effects and Risk Assessment 

      Stub, Trine (Doctoral thesis; Doktorgradsavhandling, 2014-03-28)
      Introduction Homeopathic treatment has a long tradition. Because of its widespread use as alternative therapy in Norway and Europe, but also in nations such as India, investigation into patient safety related to homeopathic treatment is important. Risk in homeopathy can be divided into direct and indirect risk. Direct risk is directly linked to the intervention itself while indirect risk is related ...

    • Sámi ethnicity as a variable. Premises and implications for population-based studies on health and living conditions in Norway 

      Pettersen, Torunn (Doctoral thesis; Doktorgradsavhandling, 2015-11-04)
      Summary: The use of Sámi ethnicity as a variable in studies aiming at quantitative knowledge on health and living conditions at the population level in contemporary Norway is challenged by in-sufficient Sámi-demographic data and blurred Sámi-ethnic boundaries. Based on the premise that the Sámi can be conceptualized as an ethnic group which is also an indigenous people, this thesis explores aspects ...

    • The secretome of cartilage, chondrocytes and chondroprogenitors : Implications for cell transplantation strategies 

      Polacek, Martin (Doctoral thesis; Doktorgradsavhandling, 2011-02-11)
      Leddbrusk har dårlig eller ingen reparasjonsevne, noe som gjør leddslitasje til et alvorlig medisinsk problem hos voksne. Flere metoder har blitt utviklet for å reparere bruskskader ved å bruke kroppens egne celler og vev. Selv om resultatene er lovende, har reparert bruskvev både dårligere kvalitet og mekaniske egenskaper, sammenlignet med friskt bruskvev. For å bedre kvaliteten til reparasjonsvevet, ...

      Food hypersensitivity (FH) has received increased attention in recent years; however, little attention has been given to the self-management work of FH. The aim of the present thesis was to explore the characteristics of women with FH, the nature of the self-management work of FH, and what makes women with FH do the self-management work of FH. The thesis consists of quantitative and qualitative ...
    • Self-regulating Physical and Mental Activities: Intensive Longitudinal Intervention Studies of Physical Fitness and Happiness 

      Thorsteinsen, Kjærsti (Doctoral thesis; Doktorgradsavhandling, 2018-11-29)
      Being active is a primary necessity in life, but it is also an essential part of what makes life worth living. This thesis explored goal pursuit activities people might not experience as pleasant in the moment, but where the self-chosen activities are still considered good and worthwhile. We hypothesized that online self-regulation interventions would be effective in increasing effortful physical ...

    • Semantic and Perceptual Models for Clinical Decision Support Systems 

      Marco Ruiz, Luis (Doctoral thesis; Doktorgradsavhandling, 2017-05-05)
      The current vision of healthcare is evolving in directions towards the secondary use of health data for producing new evidence, rapidly assimilating new knowledge, including the patient as an active component in decision-making and developing communication strategies to coordinate different areas of health care, among others. The work in these directions heavily relies on the appropriate use of ...
