      Obesity‐induced insulin resistance and type 2 diabetes mellitus can ultimately result in various complications, including diabetic cardiomyopathy. In this case, cardiac dysfunction is characterized by metabolic disturbances such as impaired glucose oxidation and an increased reliance on fatty acid (FA) oxidation. Mitochondrial dysfunction has often been associated with the altered metabolic function ...
    • Altered pharmacological effects of adrenergic agonists during hypothermia 

      Dietrichs, Erik Sveberg; Sager, Georg; Tveita, Torkjel (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-12-05)
      Rewarming from accidental hypothermia is often complicated by hypothermia-induced cardiac dysfunction, calling for immediate pharmacologic intervention. Studies show that although cardiac pharmacologic support is applied when rewarming these patients, a lack of updated treatment recommendations exist. Mainly due to lack of clinical and experimental data, neither of the international guidelines ...

      The RNA-binding protein ALYREF (THOC4) is involved in transcriptional regulation and nuclear mRNA export, though its role and molecular mode of action in breast carcinogenesis are completely unknown. Here, we identifed high ALYREF expression as a factor for poor survival in breast cancer patients. ALYREF signifcantly infuenced cellular growth, apoptosis and mitochondrial energy metabolism in ...
    • Aminoglycoside resistance in clinical Gram-negative isolates from Norway 

      Haldorsen, Bjørg Christina (Master thesis; Mastergradsoppgave, 2011-04-06)
      Aminoglycosides represent an important class of antimicrobial agents. The prevalence of aminoglycoside resistance among Gram-negative bacteria in Norway is low, but an increased prevalence among clinical isolates of Escherichia coli has been observed during the last years. The most prevalent resistance mechanism is aminoglycoside modifying enzymes. In addition, resistance may occur when bacteria ...
    • Amphipathic barbiturates as marine product mimics with cytolytic and immunogenic effects on head and neck squamous cell carcinoma cell lines 

      von Hofsten, Susannah; Langer, Manuel K; Korelin, Katja; Norvoll Magnussen, Synnøve; Ausbacher, Dominik; Anderssen, Trude; Salo, Tuula; Strøm, Morten B.; Bayer, Annette; Al-Samadi, Ahmed; Berge, gerd (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-30)
      The incidence of head and neck squamous cell carcinoma (HNSCC) is increasing and the conventional treatments for this form of cancer can be tough. Despite the success of existing immunotherapies in some HNSCC patients, many do not respond to this type of treatment. Thus, the development of novel anti-cancer therapies should be prioritized. In the current study, the anticancer activity of a panel ...
    • Analysis of 30 Y-chromosomal STR markers in the Norwegian population 

      Støtvig, Ingrid (Mastergradsoppgave; Master thesis, 2019-05-15)
      Autosomal STR-analysis is the standard method of DNA-typing in casework. However, there are forensic sample types that may contain a large fraction of female DNA and a minimal fraction of male DNA. The male fraction may not be successfully amplified using autosomal STR-analysis because it “drowns” in the female fraction. However, the analysis of male-specific YSTR markers may circumvent this obstacle. ...
    • Analysis of glomerular target structures for nephritic anti-dsDNA antibodies playing central roles in lupus nephritis 

      Tømmerås, Berit (Master thesis; Mastergradsoppgave, 2008-05)
      Systemic lupus erythematosus is an autoimmune disease characterized by the presence of autoantibodies towards nuclear antigens. Sub-populations of anti-dsDNA antibodies have the potential to bind in the kidney and thereby induce nephritis, but there is no definite distinction that separates non-pathogenic from pathogenic antibodies. There must be parameters that determine anti-dsDNA antibody binding, ...

      Barutcuoglu, Z; Airoldi, EM; Dumeaux, vanessa; Schapire, RE; Troyanskaya, Olga (Journal article; Tidsskriftartikkel; Peer reviewed, 2009)
      The heterogeneity of cancer cannot always be recognized by tumor morphology, but may be reflected by the underlying genetic aberrations. Array comparative genome hybridization (array-CGH) methods provide high-throughput data on genetic copy numbers, but determining the clinically relevant copy number changes remains a challenge. Conventional classification methods for linking recurrent alterations ...
    • Antenatal intravenous immunoglobulins in pregnancies at risk of fetal and neonatal alloimmune thrombocytopenia: comparison of neonatal outcome in treated and nontreated pregnancies

      <i>Klebsiella</i> spp. are a major cause of both nosocomial and community acquired infections, with <i>K. pneumoniae</i> being responsible for most human infections. Although <i>Klebsiella</i> spp. are present in a variety of environments, their distribution in the sea and the associated antibiotic resistance is largely unknown. In order to examine prevalence of <i>K. pneumoniae</i> and related ...
    • Antibiotics to outpatients in Norway—Assessing effect of latitude and municipality population size using quantile regression in a cross-sectional study. 

      Haugen, Pål; Simonsen, Gunnar Skov; Primicerio, Raul; Furberg, Anne-Sofie; Småbrekke, Lars (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-09-29)
      High antibiotic consumption rates are associated to high prevalence of antimicrobial resistance. Geographical differences in dispensing rates of antibiotics are frequently analysed using statistical methods addressing the central tendency of the data. Yet, examining extreme quantiles may be of equal or greater interest if the problem relates to the extremes of consumption rates, as is the case for ...
    • Antibiotikaresistens - globalt, lokalt, i dag och i morgon 

      Lund, Bodil Kristina; Klinge, Björn; Larsen, Tove; Olsvik, Ørjan; Vällimaa, Hannamari (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-09)
      Antibiotikaresistensen ökar kraftigt, och i dag pågår ett internationellt samarbete för att motverka detta. Antibiotikaförskrivningen i tandvården i de nordiska länderna är ur ett internationellt perspektiv låg. Det finns dock en del indikationer på att denna kan reduceras ytterligare.
