    • Exploring and Targeting Novel Cancer Networks in Multidrug Resistant Neuroblastoma 

      Olsen, Lotte (Doctoral thesis; Doktorgradsavhandling, 2020-06-19)
      High-risk neuroblastoma has an overall survival of only 50%, and alternative treatment options for this patient group are needed. In this thesis, I will present novel insight into potential anti-tumor mechanisms for high-risk neuroblastoma. Firstly, our investigations have revealed a tumor suppressor function of the microRNA (miRNA) <i>miR-323a-3p</i> in neuroblastoma cells, and that this miRNA ...

      Franklin-Alming, Fiona; Kaspersen, Håkon; Hetland, Marit A. K.; Bakksjø, Ragna-Johanne; Nesse, Live L.; Leangapichart, Thongpan; Löhr, Iren Høyland; Telke, Amar; Sunde, Marianne (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-07)
      Klebsiella pneumoniae is a well-studied human pathogen for which antimicrobial resistant and hypervirulent clones have emerged globally. K. pneumoniae is also present in a variety of environmental niches, but currently there is a lack of knowledge on the occurrence and characteristics of K. pneumoniae from non-human sources. Certain environmental niches, e.g., animals, may be associated with high ...
    • Exploring mitochondrial quality control mechanisms and mitochondria-lipid droplet interactions in cardiac cell models 

      Godtliebsen, Gustav (Doctoral thesis; Doktorgradsavhandling, 2024-01-11)
      Mitochondria are the main energy producing units (organelles) in cardiac cells (cardiomyocytes). Cardiomyocytes have especially high mitochondrial content due to the heart’s continuous energy-intensive pumping. Studies of heart disease (such as heart failure) indicate that mitochondrial dysfunction is central to disease progression. There are many cellular mechanisms that protect mitochondria from ...

    • Exploring patient safety in rural general practice - a mixed-methods approach 

      Harbitz, Martin Bruusgaard (Doctoral thesis; Doktorgradsavhandling, 2022-11-08)
      <p>Unsafe medical practices and incidents where safety hazards cause harm to patients occur daily in general practice. The costs to society, health care personnel and individual patients are substantial and deserve attention. “Hazards” can be regarded as local error-producing factors, latent failures, which create conditions for unsafe medical practice to take place. “Harm” occurs when these conditions ...

    • Exploring the determinants of reinvestment decisions: Sense of personal responsibility, preferences, and loss framing 

      Doerflinger, Johannes T.; Martiny-Huenger, Torsten; Gollwitzer, Peter M. (Journal article; Tidsskriftartikkel, 2023-01-12)
      Two potentially costly errors are common in sequential investment decisions: sticking too long to a failing course of action (escalation of commitment), and abandoning a successful course of action prematurely. Past research has mostly focused on escalation of commitment, and identified three critical determinants: personal responsibility, preferences for prior decisions, and decision framing. We ...

    • Exploring the gender specific association between use of complementary and alternative medicine and alcohol consumption and injuries caused by drinking. The sixth Tromsø study 

      Sivertsen, Kristina (Master thesis; Mastergradsoppgave, 2017-08-25)
      Background: Previous studies have found that the use of complementary and alternative medicine (CAM) is associated with several characteristic, such as female gender, higher education and higher income. However, studies investigating the relationship between alcohol consumption patterns and different CAM approaches have so far been limited. Harmful use of alcohol has detrimental consequences to ...
    • Exploring the genomes of the Norwegian vancomycin resistant enterococci 

      AL-Rubaye, Mushtaq Talib Shawi (Doctoral thesis; Doktorgradsavhandling, 2023-03-24)
      Enterococci are gram-positive commensals in the human gut microbiota that may cause severe infections, especially in immunocompromised and hospitalised patients. Their ability to accumulate antimicrobial resistance and virulence genes has been vital in their evolution into leading pathogens. Vancomycin resistant enterococci (VRE) are among the most important resistant pathogens causing outbreaks ...
    • Exploring the in vitro expansion of CD4 T cells. For improved culturing of CD4 T cells linked to FNAIT 

      von Hofsten, Susannah (Master thesis; Mastergradsoppgave, 2018-05-15)
      Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a rare disease that may cause serious bleedings in the fetus or neonate of a woman who has developed antibodies against the fetus’ platelets. Development of FNAIT has been linked to the presence of platelet reactive CD4 T cells that help B cells to develop into antibody producing plasma cells. To be able to conduct research on such T cells, ...

    • Exploring the overlapping binding sites of ifenprodil and EVT‐101 in GluN2B‐containing NMDA receptors using novel chicken embryo forebrain cultures and molecular modeling 

      Fjelldal, Marthe Fredheim; Freyd, Thibaud; Evenseth, Linn; Sylte, Ingebrigt; Ring, Avi; Paulsen, Ragnhild Elisabeth (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-30)
      N‐methyl‐d‐aspartate receptors (NMDAR) are widely expressed in the brain. GluN2B subunit‐containing NMDARs has recently attracted significant attention as potential pharmacological targets, with emphasis on the functional properties of allosteric antagonists. We used primary cultures from chicken embryo forebrain (E10), expressing native GluN2B‐containing NMDA receptors as a novel model system. ...
