    • Early sexual behaviour and Chlamydia trachomatis infection - a population based cross-sectional study on gender differences among adolescents in Norway. 

      Gravningen, Kirsten Midttun; Furberg, Anne-Sofie; Simonsen, Gunnar Skov; Wilsgaard, Tom (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Early sexual behaviour has been shown to differ significantly between genders, but few studies have addressed this topic to explain the commonly observed differences in chlamydia rates between adolescent girls and boys. Our study aimed to determine chlamydia prevalence in adolescents aged 15–20 years in a high-incidence area in Norway, and to identify gender-specific early sexual behaviours associated ...

    • The effect of interleukin-17F on vasculogenic mimicry in oral tongue squamous cell carcinoma 

      Almahmoudi, Rabeia; Salem, Abdelhakim; Hadler-Olsen, Elin Synnøve; Svineng, Gunbjørg; Salo, Tuula; Al-Samadi, Ahmed (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-20)
      Oral tongue squamous cell carcinoma (OTSCC) is one of the most common cancers worldwide and is characterized by early metastasis and poor prognosis. Recently, we reported that extracellular interleukin-17F (IL-17F) correlates with better disease-specific survival in OTSCC patients and has promising anticancer effects in vitro. Vasculogenic mimicry (VM) is the formation of an alternative vasculogenic ...

    • Effect of Perioperative Dexamethasone and Different NSAIDs on Anastomotic Leak Risk: A Propensity Score Analysis 

      Rushfeldt, Christian; Agledahl, Uwe; Sveinbjørnsson, Baldur; Søreide, Kjetil; Wilsgaard, Tom (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-11)
      Background Perioperative use of nonsteroidal anti-inflammatory drugs (NSAIDs) is associated with risk of anastomotic leak (AL). However, concomitant use of other drugs could infer a bias in risk assessment. Thus, we aimed to interrogate the risk of AL associated with NSAIDs and steroids used perioperatively. Methods This study includes a consecutive series of patients having surgery involving ...

      Resolvin D1 (RvD1) is a pro-resolving lipid mediator of inflammation, endogenously synthesized from omega-3 docosahexaenoic acid. The purpose of this study was to investigate the effect of RvD1 on bone regeneration using a rat calvarial defect model. Collagen 3D nanopore scaffold (COL) and Pluronic F127 hydrogel (F127) incorporated with RvD1 (RvD1-COL-F127 group) or COL and F127 (COL-F127 group) ...

      Næsheim, Torvind; How, Ole-Jakob; Myrmel, Truls (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-12)
      <p><i>Introduction - </i>Riociguat is a soluble guanylate cyclase stimulator approved for the treatment of pulmonary hypertension. Its effect on cardiometabolic efficiency is unknown. A potential cardiac energy sparing effect of this drug could imply a positive prognostic effect, particularly in patients with right heart failure from pulmonary hypertension. <p><i>Method - </i>We infused Riociguat ...

    • The effect of stimulation therapy and donepezil on cognitive function in Alzheimer's disease. A community based RCT with a two-by-two factorial design 

      Andersen, Fred; Viitanen, Matti; Halvorsen, Dag; Straume, Bjørn; Wilsgaard, Tom; Engstad, Torgeir (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Progressive neurodegeneration in Alzheimer’s disease (AD) induces cognitive deterioration, and there is controversy regarding the optimal treatment strategy in early AD. Stimulation therapy, including physical exercise and cholinesterase inhibitors are both reported to postpone cognitive deterioration in separate studies. We aimed to study the effect of stimulation therapy and the additional effect ...

    • Effect of the Large and Small T-Antigens of Human Polyomaviruses on Signaling Pathways 

      Moens, Ugo; Macdonald, Andrew (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-12)
      Viruses are intracellular parasites that require a permissive host cell to express the viral genome and to produce new progeny virus particles. However, not all viral infections are productive and some viruses can induce carcinogenesis. Irrespective of the type of infection (productive or neoplastic), viruses hijack the host cell machinery to permit optimal viral replication or to transform the ...

    • The effect of traditional cupping on pain and mechanical thresholds in patients with chronic nonspecific neck pain : a randomised controlled pilot study 

      Lauche, Romy; Cramer, Holger; Hohmann, Claudia; Choi, Kyung-Eun; Rampp, Thomas; Saha, Felix Joyonto; Musial, Frauke; Langhorst, Jost; Dobos, Gustav J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Cupping has been used since antiquity in the treatment of pain conditions. In this pilot study, we investigated the effect of traditional cupping therapy on chronic nonspecific neck pain (CNP) and mechanical sensory thresholds. Fifty CNP patients were randomly assigned to treatment (TG, n = 25) or waiting list control group (WL, n = 25). TG received a single cupping treatment. Pain at rest (PR), ...

    • Effect of Unfractionated Heparin on TFPI Elimination 

      Øie, Cristina Ionica; Appa, Rupa Shree; Brodin, Ellen; Hilden, Ida; Smedsrød, Bård; Hansen, John-Bjarne (Journal article; Tidsskriftartikkel, 2010)
      Background: Tissue factor pathway inhibitor (TFPI) plays an important role for the anticoagulant effect of heparin. Depletion of intravascular TFPI by treatment with unfractionated heparin (UFH), and not by low molecular weight heparin (LMWH), has been suggested to explain the superiority of LMWH in treatment of both arterial and venous thrombosis. The present study was undertaken to investigate ...

    • Effectiveness of school-based preventive interventions on adolescent alcohol use: a meta-analysis of randomized controlled trials 

      Strøm, Henriette Kyrrestad; Adolfsen, Frode; Fossum, Sturla; Kaiser, Sabine; Martinussen, Monica (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-12-13)
      Background - Preventive interventions for adolescents are an important priority within school systems. Several interventions have been developed, but the effectiveness of such interventions varies considerably between studies. The purpose of this study was to assess the effectiveness of universal school-based prevention programs on alcohol use among adolescents by using meta-analytic techniques.<p ...

    • Effects of Agricultural Pesticides in Aquafeeds on Wild Fish Feeding on Leftover Pellets Near Fish Farms 

      Olsvik, Pål Asgeir; Larsen, Anett Kristin; Berntssen, Marc; Goksøyr, Anders; Karlsen, Odd Andre; Yadetie, Fekadu; Sanden, Monica; Kristensen, Torstein (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-26)
      Screening has revealed that modern-day feeds used in Atlantic salmon aquaculture might contain trace amounts of agricultural pesticides. To reach slaughter size, salmon are produced in open net pens in the sea. Uneaten feed pellets and undigested feces deposited beneath the net pens represent a source of contamination for marine organisms. To examine the impacts of long-term and continuous dietary ...

    • The Effects of Metformin on Age-Related Changes in the Liver Sinusoidal Endothelial Cell 

      Hunt, Nicholas J; Lockwood, Glen P; Kang, Sun; Pulpitel, Tamara; Clark, Ximonie; Mao, Hong; McCourt, Peter Anthony; Cooney, Greg; Wali, Jibran; Le Couteur, Frank; Le Couteur, David G; Cogger, Victoria C (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-14)
      Age-related changes in the liver sinusoidal endothelium, particularly the reduction in fenestrations, contribute to insulin resistance in old age. Metformin impacts on the aging process and improves insulin resistance. Therefore, the effects of metformin on the liver sinusoidal endothelium were studied. Metformin increased fenestrations in liver sinusoidal endothelial cells isolated from both young ...

    • Efficacy of mecillinam against clinical multidrug-resistant Escherichia coli in a murine urinary tract infection model 

      Zykov, Ilya Nikolaevich; Frimodt-Møller, Niels; Småbrekke, Lars; Sundsfjord, Arnfinn; Samuelsen, Ørjan (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-23)
      Pivmecillinam, a pro-drug of mecillinam, has been used extensively in Scandinavia for the treatment of acute lower urinary tract infections (UTIs) caused by Enterobacterales. It is still an attractive first-line drug for the empirical treatment of UTIs owing to the low prevalence of resistance as well as its favourable impact on the intestinal microbiota as a pro-drug and good in vitro efficacy ...
