    • Expression of S100A4, ephrin-A1 and osteopontin in non-small cell lung cancer 

      Rud, Ane Kristine Kongsgaard; Lund-Iversen, Marius; Berge, Gisle; Brustugun, Odd Terje; Solberg, Steinar; Mælandsmo, Gunhild; Pedersen, Kjetil Boye (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      The metastasis-promoting protein S100A4 induces expression of ephrin-A1 and osteopontin in osteosarcoma cell lines. The aim of this study was to investigate S100A4-mediated stimulation of ephrin-A1 and osteopontin in non-small cell lung cancer (NSCLC) cell lines, and to characterize the expression of these biomarkers in primary tumor tissue from NSCLC patients. Four NSCLC cell lines were treated ...

      Knutsen, Erik; Lellahi, Seyed Mohammad; Aure, Miriam Ragle; Nord, Silje; Fismen, Silje; Larsen, Kenneth Bowitz; Tellez Gabriel, Marta; Hedberg, Annica; Bjørklund, Sunniva; Bofin, Anna M.; Mælandsmo, Gunhild Mari; Sørlie, Therese; Mortensen, Elin Synnøve; Perander, Maria (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-28)
      The long non-coding RNA <i>NEAT1</i> locus is transcribed into two overlapping isoforms, <i>NEAT1_1</i> and <i>NEAT1_2</i>, of which the latter is essential for the assembly of nuclear paraspeckles. <i>NEAT1</i> is abnormally expressed in a wide variety of human cancers. Emerging evidence suggests that the two isoforms have distinct functions in gene expression regulation, and recently it was shown ...

      Nunes-Xavier, Caroline Elisabeth; Emaldi, Maite; Mingo, Janire; Øyjord, Tove Ragnhild; Mælandsmo, Gunhild Mari; Fodstad, Øystein; Errarte, Peio; Larrinaga, Gorka; Llarena, Roberto; López, José I.; Pulido, Rafael (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-05)
      Renal cancer cells constitute a paradigm of tumor cells with a glycolytic reprogramming which drives metabolic alterations favouring cell survival and transformation. We studied the expression and activity of pyruvate dehydrogenase kinases (PDK1-4), key enzymes of the energy metabolism, in renal cancer cells. We analysed the expression, subcellular distribution and clinicopathological correlations ...

    • Extending the EQ-5D: the case for a complementary set of 4 psycho-social dimensions 

      Chen, Gang; Olsen, Jan Abel (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-20)
      Objectives - The EQ-5D is the most widely applied preference-based health-related quality of life measure. However, concerns have been raised that the existing dimensional structure lacks sufficient components of mental and social aspects of health. This study empirically explored the performance of a coherent set of four psycho-social bolt-ons: Vitality; Sleep; Personal relationships; and Social ...
    • Extending the usefulness of the verbal memory test: The promise of machine learning 

      Chandler, Chelsea; Holmlund, Terje Bektesevic; Foltz, Peter W.; Cohen, Alex S.; Elvevåg, Brita (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-19)
      The evaluation of verbal memory is a core component of neuropsychological assessment in a wide range of clinical and research settings. Leveraging story recall to assay neurocognitive function could be made more useful if it were possible to administer frequently (i.e., would allow for the collection of more patient data over time) and automatically assess the recalls with machine learning methods. ...
    • Extent of Preoperative False Lumen Thrombosis Does Not Influence Long-Term Survival in Patients With Acute Type A Aortic Dissection 

      Larsen, Magnus; Bartnes, Kristian; Tsai, TT; Eagle, KA; Evangelista, Arturo; Nienaber, CA; Suzuki, Toru; Fattori, Rossella; Forehlich, James B; Hutchinson, Stuart J.; Sundt, Thoralf M.; Januzzi, James L.; Isselbacher, Eric M.; Montgomery, Daniel G.; Myrmel, Truls (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Background-—Partial thrombosis of the false lumen has been related to aortic growth, reoperations, and death in the chronic phase of type B and repaired type A aortic dissections. The impact of preoperative false lumen thrombosis has not been studied previously. We used data from a contemporary, multinational database on aortic dissections to evaluate whether different degrees of preoperative ...
    • Extent, Awareness and Perception of Dissemination Bias in Qualitative Research: An Explorative Survey 

      Toews, Ingrid; Glenton, Claire; Lewin, Simon; Berg, Rigmor C.; Noyes, Jane; Booth, Andrew; Marusic, Ana; Malicki, Mario; Munthe-Kaas, Heather M.; Meerpohl, Joerg J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-03)
      <b>Background</b> <br> Qualitative research findings are increasingly used to inform decision-making. Research has indicated that not all quantitative research on the effects of interventions is disseminated or published. The extent to which qualitative researchers also systematically underreport or fail to publish certain types of research findings, and the impact this may have, has received ...

      Schierenberg, Alwin; Minnaard, Margaretha C.; Hopstaken, Rogier M.; Van De Pol, Alma C.; Broekhuizen, Berna D.L.; De Wit, Niek J.; Reitsma, Johannes B.; Van Vugt, Saskia F.; Graffelman, Aleida W.; Melbye, Hasse; Rainer, Timothy H.; Steurer, Johann; Holm, Anette; Gonzales, Ralph; Dinant, Geert-Jan; De Groot, Joris A.H.; Verheij, Theo J.M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-02-26)
      Background:<br> Pneumonia remains difficult to diagnose in primary care. Prediction models based on signs and symptoms (S&S) serve to minimize the diagnostic uncertainty. External validation of these models is essential before implementation into routine practice. In this study all published S&S models for prediction of pneumonia in primary care were externally validated in the individual patient ...

      Extracellular vesicles (EVs)—particularly exosomes and microvesicles (MVs)—are attracting considerable interest in the cardiovascular field as the wide range of their functions is recognized. These capabilities include transporting regulatory molecules including different RNA species, lipids, and proteins through the extracellular space including blood and delivering these cargos to recipient ...
    • Extracorporeal rewarming from experimental hypothermia: Effects of hydroxyethyl starch versus saline priming on fluid balance and blood flow distribution 

      Schanche, Torstein Lindahl; Kondratyev, Timofey; Tveita, Torkjel (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-29)
      Rewarming by extracorporeal circulation (ECC) is the recommended treatment for accidental hypothermia patients with cardiac instability. Hypothermia, along with initiation of ECC, introduces major changes in fluid homeostasis and blood flow. Scientific data to recommend best practice use of ECC for rewarming these patients is lacking, and no current guidelines exist concerning the choice of priming ...
