      Björkhem, Ingemar; Diczfalusy, Ulf; Lövgren-Sandblom, Anita; Starck, Lena; Jonsson, Monica; Tallman, Keri; Schirmer, Henrik; Ousager, Lillian Bomme; Crick, Peter J; Wang, Yuqing; Griffiths, William J; Guengerich, F.Peter (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-04-25)
      Abstract A new mechanism for formation of 7-ketocholesterol was recently described involving cytochrome P-450 (CYP)7A1-catalyzed conversion of 7-dehydrocholesterol into 7-ketocholesterol with cholesterol-7,8-epoxide as a side product. Some patients with cerebrotendinous xanthomatosis (CTX) and all patients with Smith-Lemli-Opitz syndrome (SLO) have markedly increased levels of 7-dehydrocholesterol ...

      Escudero-Arnanz, Oscar; Rodríguez-Álvarez, Joaquín; Mikalsen, Karl Øyvind; Jenssen, Robert; Soguero-Ruiz, Cristina (Conference object; Konferansebidrag, 2021)
      The acquisition of Antimicrobial Multidrug Resistance (AMR) in patients admitted to the Intensive Care Units (ICU) is a major global concern. This study analyses data in the form of multivariate time series (MTS) from 3476 patients recorded at the ICU of University Hospital of Fuenlabrada (Madrid) from 2004 to 2020. 18% of the patients acquired AMR during their stay in the ICU. The goal of ...
    • The One-stop trial : does electronic referral and booking by the general practitioner (GPs) to outpatient day case surgery reduce waiting time and costs? A randomized controlled trial protocol 

      Augestad, Knut Magne; Revhaug, Arthur; Vonen, Barthold; Johnsen, Roar; Lindsetmo, Rolv-Ole (Journal article; Tidsskriftartikkel, 2008-08-11)
      Background: Waiting time and costs from referral to day case outpatient surgery are at an unacceptably high level. The waiting time in Norway averages 240 days for common surgical conditions. Furthermore, in North Norway the population is scattered throughout a large geographic area, making the cost of travel to a specialist examination before surgery considerable. Electronic standardised referrals ...

      Sørlie, Andreas; Gulati, Sasha; Giannadakis, Charalampis; Carlsen, Sven Magnus; Salvesen, Øyvind; Nygaard, Øystein Petter; Solberg, Tore (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-09-02)
      Introduction:<br>Since the introduction of lumbar microdiscectomy in the 1970’s, many studies have attempted to compare the effectiveness of this method with that of standard open discectomy with conflicting results. This observational study is designed to compare the relative effectiveness of microdiscectomy (MD) with open discectomy (OD) for treating lumbar disc herniation, -within a large cohort, ...

      Lamsal, Apsana; Andersen, Sonja Benedikte; Johansson, Ida; Vietri, Marina; Bokil, Ansooya Avinash; Kurganovs, Natalie Jayne; Rylander, Felicia; Bjørkøy, Geir; Pettersen, Kristine; Giambelluca, Miriam Soledad (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-07)
      Background To our current understanding, solid tumors depend on suppressed local immune reactions, often elicited by the interaction between tumor cells and tumor microenvironment (TME) components. Despite an improved understanding of anti-cancer immune responses in the TME, it is still unclear how immuno-suppressive TME are formed and how some cancer cells survive and metastasize.<p> <p>Methods ...
    • Optimal sleep duration in the subarctic with respect to obesity risk is 8-9 hours 

      Johnsen, May Trude; Wynn, Rolf; Bratlid, Trond (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Sleep duration, chronotype and social jetlag have been associated with body mass index (BMI) and abdominal obesity. The optimal sleep duration regarding BMI has previously been found to be 7–8 hours, but these studies have not been carried out in the subarctic or have lacked some central variables. The aims of our study were to examine the associations between sleep variables and body composition ...

      Caglayan, Safak; Hansen, John Bjarne; Snir, Omri (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-15)
      Background - A comprehensive dissection of the role of microRNAs (miRNAs) in gene regulation and subsequent cell functions requires a specific and efficient knockdown or overexpression of the miRNA of interest; these are achieved by transfecting the cell of interest with a miRNA inhibitor or a miRNA mimic, respectively. Inhibitors and mimics of miRNAs with a unique chemistry and/or structural ...

    • Outcomes in pancreas transplantation with exocrine drainage through a duodenoduodenostomy versus duodenojejunostomy 

      Lindahl, Jørn Petter Hanto; Horneland, Rune; Nordheim, Espen; Hartmann, Anders; Aandahl, Einar Martin; Grzyb, Krzysztof; Haugaa, Håkon; Kjøsen, Gisle; Åsberg, Anders; Jenssen, Trond Geir (Journal article; Tidsskriftartikkel, 2017-08-23)
      Until recently, pancreas transplantation has mostly been performed with exocrine drainage via duodenojejunostomy (DJ). Since 2012, DJ was substituted with duodenoduodenostomy (DD) in our hospital, allowing endoscopic access for biopsies. This study assessed safety profiles with DD versus DJ procedures and clinical outcomes with the DD technique in pancreas transplantation. DD patients (n = 117; 62 ...

    • Overexpression of the HIF Hydroxylases PHD1, PHD2, PHD3 and FIH Are Individually and Collectively Unfavorable Prognosticators for NSCLC Survival 

      Andersen, Sigve; Dønnem, Tom; Stenvold, Helge; Al-Saad, Samer; Al-Shibli, Khalid Ibrahim; Busund, Lill-Tove; Bremnes, Roy M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Hypoxia induced factors (HIFs) are at the heart of the adaptive mechanisms cancer cells must implement for survival. HIFs are regulated by four hydroxylases; Prolyl hydroxylase (PHD)-1,-2,-3 and factor inhibiting HIF (FIH). We aimed to investigate the prognostic impact of these oxygen sensors in NSCLC. Tumor tissue samples from 335 resected stages I to IIIA NSCLC patients was obtained and tissue ...
