  • Detection of tissue factor in platelets: why is it so troublesome? 

    Østerud, Bjarne; Bouchard, Beth A (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-30)
    Tissue factor (TF) is the most important trigger for the extrinsic coagulation pathway. TF, earlier denoted as thromboplastin, has always been a mystery since its discovery due to its abundant presence in most human tissues but not blood. The latter has been extensively studied in a vast quest for possible sources of blood-borne TF yielding many conflicting findings and confusing conclusions regarding ...

    Peres, Lauren C.; Mallen, Adrianne R.; Townsend, Mary K.; Poole, Elizabeth M.; Trabert, Britton; Allen, Naomi E.; Arslan, Alan A.; Dossus, Laure; Fortner, Renee T.; Gram, Inger T.; Hartge, Patricia; Idahl, Annika; Kaaks, Rudolf; Kvaskoff, Marina; Magliocco, Anthony M.; Merritt, Melissa A.; Quirós, Ramón; Tjonneland, Anne; Trichopoulou, Antonia; Tumino, Rosario; van Gils, Carla H.; Visvanathan, Kala; Wentzensen, Nicolas; Zeleniuch-Jacquotte, Anne; Tworoger, Shelley S. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-28)
    Growing epidemiologic evidence supports chronic inflammation as a mechanism of ovarian carcinogenesis. An association between a circulating marker of inflammation, C-reactive protein (CRP), and ovarian cancer risk has been consistently observed, yet, potential heterogeneity of this association by tumor and patient characteristics has not been adequately explored. In this study, we pooled data from ...
  • Sex-specific reference ranges of cerebroplacental and umbilicocerebral ratios: A longitudinal study 

    Acharya, Ganesh; Ebbing, Cathrine; Karlsen, Henriette Odland; Kiserud, Torvid; Rasmussen, Svein (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-10)
    <p><i>Objectives - </i>The ratio of middle cerebral artery (MCA) pulsatility index (PI) to umbilical artery (UA) PI, i.e. cerebro‐placental ratio (CPR), has been suggested as a measure of fetal “brain sparing” phenomenon reflecting redistribution of fetal cardiac output as a response to placental insufficiency. Observational studies have shown that low CPR values predict increased risk of adverse ...

    Cohen, Alex S.; Fedechko, Taylor L.; Schwartz, Elana K.; Le, Thanh P.; Foltz, Peter W.; Bernstein, Jared; Cheng, Jian; Rosenfeld, Elizabeth; Elvevåg, Brita (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-01)
    Accurate prediction of risk-states in Serious Mental Illnesses (SMIs) is critical for reducing their massive societal burden. Risk-state assessments are notably inaccurate. Recent innovations, including widely available and inexpensive mobile technologies for ambulatory “biobehavioral” data, can reshape risk assessment. To help understand and accelerate clinician involvement, we surveyed 90 ...
  • Murine models for studying treatment, prevention and pathogenesis of FNAIT 

    Rasmussen, Trude Victoria; Ahlen, Maria Therese (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-31)
    Maternal alloimmunization to paternally inherited antigens on fetal/neonatal platelets can cause fetal/neonatal alloimmune thrombocytopenia (FNAIT) after antibody-mediated removal of platelets from the fetal circulation. The complications vary from mild bleeding symptoms to severe intracranial hemorrhage and subsequent neurological impairment or death. Studies on <i>in vivo</i> mechanisms are ...
  • Second re-irradiation: A delicate balance between safety and efficacy 

    Nieder, Carsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-08)
    Except for straightforward palliative indications such as painful bone metastases, re-irradiation is often characterized by a narrow therapeutic window and the potential for decreased efficacy and increased toxicity, especially if the cumulative total dose from both courses is high. Second re-irradiations tend to pose even bigger challenges and are thus offered in a restrictive manner to highly ...
