      Bankes, Nigel; Mascher, Sharon; Olszynski, Martin (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
    • Can nanomedicine improve the semen quality? The potentials of liposomal curcumin. 

      Wu, Iren Yeeling (Master thesis; Mastergradsoppgave, 2015-05-13)
      INTRODUCTION: Worldwide, 10-15 % couples are infertile, and 50 % of the couples seeking assisted reproductive techniques do so because of defective sperm quality. The semen quality can be directly linked to oxidative stress (OS). Due to high metabolic rates and weak anti-oxidant systems, sperm cells are unable to defend against OS produced exogenously and endogenously. Vitamin C and/or vitamin E are ...

      Rossen, Janne; Klungsøyr, Kari; Albrechtsen, Susanne; Løkkegård, Ellen; Rasmussen, Steen; Bergholt, Thomas; Skjeldestad, Finn Egil (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-07)
      <p><i>Introduction</i>: Maternal age is an established risk factor for cesarean section; epidural analgesia and oxytocin augmentation may modify this association. We investigated the effects and interactions of oxytocin augmentation, epidural analgesia and maternal age on the risk of cesarean section.</p> <p><i>Material and methods</i>: In all, 416 386 nulliparous women with spontaneous onset of ...
    • Can structural indicators explain gender difference in life expectancy (LE) at birth among WHO member countries? 

      Bye, Stefan (Master thesis; Mastergradsoppgave, 2012-06)
      Forskjellen i life expectancy at birth mellom kjønn varierer fra land til land og i de fleste tilfellene så lever kvinner lengre enn menn. Det globale gjennomsnittet er på ca 7% lengre levetid for kvinner enn menn, men man har forskjeller som er helt opp i 23%. Det finnes etablerte hypoteser på hvorfor kvinner lever lengre enn menn og i denne oppgaven vil jeg se på hvordan sosiale og strukturelle ...

    • Can vitamin D3 supplementation prevent bone loss in persons with MS? 

      Steffensen, Linn Hofsøy (Doctoral thesis; Doktorgradsavhandling, 2012-12-13)
      In persons with Multiple sclerosis (MS) low bone mineral density (BMD) is more prevalent when compared with healthy controls and MS may be a possible cause of secondary osteoporosis. BMD is primarily determined by genetic and hormonal factors, body mass index, physical activity and intake of calcium and vitamin D. Vitamin D level at 50 nmol/L or higher is classified as sufficient, however, optimal ...
    • Can we rely on simulated patients' satisfaction with their consultation for assessing medical students' communication skills? A cross-sectional study 

      Gude, Tore; Grimstad, Hilde; Holen, Are; Anvik, Tor; Baerheim, Anders; Fasmer, Ole Bernt; Hjortdahl, Per; Vaglum, Per Jørgen Wiggen (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-12-18)
      Background: In medical education, teaching methods offering intensive practice without high utilization of faculty resources are needed.

    • Cancer and venous thromboembolism 

      Jensvoll, Hilde (Doctoral thesis; Doktorgradsavhandling, 2015-10-02)
      Venøs tromboembolisme (VTE) er et samlebegrep for lungeemboli og dyp venetrombose. VTE rammer ofte kreftpasienter og representerer en ledende dødsårsak i denne pasient gruppen. Dette understreker viktigheten av å kartlegge risikofaktorer for kreft-relatert VTE for å muliggjøre forebyggende behandling hos pasienter med høy risiko. En VTE hendelse kan også være det første symptomet på en bakenforliggende ...
    • Cancer associated fibroblasts in stage I-IIIA NSCLC: Prognostic impact and their correlations with tumor molecular markers 

      Kilvær, Thomas Karsten; Rakaeekhanehkenari, Mehrdad; Hellevik, Turid; Al-Saad, Samer; Paulsen, Erna-Elise; Busund, Lill-Tove; Dønnem, Tom; Martinez, Inigo Zubiavrre (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-08-07)
      Background Cancer Associated Fibroblasts (CAFs) are thought to regulate tumor growth and metastasis. Fibroblast Activating Protein 1 (FAP-1) is a marker for fibroblast activation and by many recognized as the main marker of CAFs. Alpha Smooth Muscle Actin (α-SMA) is a general myofibroblast marker, and can be used to identify CAFs. This study investigates the prognostic impact of FAP-1 and α-SMA ...
    • Cancer cervicis uteri i Sub-Sahara Afrika : en litteraturstudie 

      Hana, Johan (Master thesis; Mastergradsoppgave, 2011-09-15)
      Insidensen av livmorhalskreft i regionen er blant verdens høyeste. Kontinentet er hardt rammet av HIV/AIDS, og da denne sykdommen medfører smitte av andre og flere typer onkogene HPV, samt raskere progresjon av dysplasi, vanskeliggjør dette arbeidet med å få ned nye krefttilfeller. Videre viser studier generelt manglende kunnskap om livmorhalskreft i befolkningen, også blant velutdannende og urbane ...
