      Infected chronic skin wounds and other skin infections are increasingly putting pressure on the health care providers and patients. The pressure is especially concerning due to the rise of antimicrobial resistance and biofilm-producing bacteria that further impair treatment success. Therefore, innovative strategies for wound healing and bacterial eradication are urgently needed; utilization ...
    • Differentially Expressed MicroRNAs in Meningiomas Grades I and II Suggest Shared Biomarkers with Malignant Tumors 

      El-Gewely, Mohamed Raafat; Andreassen, Morten; Walquist, Mari; Ursvik, Anita; Knutsen, Erik; Nystad, Mona; Coucheron, Dag H; Myrmel, Kristin Smistad; Hennig, Rune; Johansen, Steinar D (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-03-03)
      Meningiomas represent the most common primary tumors of the central nervous system, but few microRNA (miRNA) profiling studies have been reported so far. Deep sequencing of small RNA libraries generated from two human meningioma biopsies WHO grades I (benign) and II (atypical) were compared to excess dura controls. Nineteen differentially expressed miRNAs were validated by RT-qPCR using tumor RNA ...
    • Dyes in Disguise: characterization of fluorescently labeled liposomes 

      Cauzzo, Jennifer; Nystad, Mona; Holsæter, Ann Mari; Basnet, Purusotam; Skalko-Basnet, Natasa (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-09)
      The rather limited success of translation from basic research to clinical application has been highlighted as a major issue in the nanomedicine field. To identify the factors influencing the applicability of nanosystems as drug carriers and potential nanomedicine, we focused on following their fate through fluorescence-based assays, namely flow cytometry and imaging. These methods are often used to ...

    • Laeverin Protein Expression in Normal and Preeclamptic Placentas using Tissue Microarray Analysis 

      Nystad, Mona; Sitras, Vasilis; Nordbakken, Cecilie Valborg; Pedersen, Mona Irene; Acharya, Ganesh (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-21)
      <p><i>Introduction - </i>Laeverin is a placenta‐specific protein that is normally expressed in the plasma membrane of human trophoblasts. In previous studies, we showed higher expression levels of laeverin gene in preeclamptic compared with normal placentas and found that laeverin protein was ectopically expressed in the cytoplasm of the preeclamptic placentas. Our objective was to investigate ...
    • Longitudinal reference ranges for maternal plasma laeverin, and its role as a potential biomarker of preeclampsia 

      Nystad, Mona; Sitras, Vasilis; Flo, Kari; Widnes, Christian; Vårtun, Åse; Wilsgaard, Tom; Acharya, Ganesh (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-11-25)
      Background: Laeverin is a placenta-specific membrane-bound aminopeptidase. In this study we wanted to: 1) serially measure plasma levels of laeverin in healthy women during the second half of pregnancy and postpartum, 2) determine whether laeverin is differently expressed at 22–24 weeks in women who later develop preeclampsia compared to controls, 3) compare laeverin protein expression in placenta ...
    • Maternal serum laeverin (aminopeptidase Q) measured in the first trimester of pregnancy does not predict preeclampsia 

      Pihl, Kasper; Sørensen, Steen; Nystad, Mona; Acharya, Ganesh; Jørgensen, Finn S. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-22)
      <i>Objective</i>: The aim of this study was to compare the laeverin level in maternal serum from first trimester (11–14 weeks) of pregnancy between normal pregnancies and pregnancies that later developed preeclampsia (PE).<p><p> <i>Material and methods</i>: This was a case-cohort study. The laeverin concentration was measured in cases with preterm PE (<i>n</i> = 55), term PE (<i>n</i> = 95), and ...
    • Platelet alloimmunization is associated with low grade chronic histiocytic intervillositis - A new link to a rare placental lesion? 

      Nedberg, Nora Hersoug; Turowski, Gitta Erika; Guz, Katarzyna; Przytuła, Ewa; Uhrynowska, Małgorzata; Roald, Borghild; Husebekk, Anne; Sitras, Vasilis; Nystad, Mona; Dębska, Marzena; Brojer, Ewa; Tiller, Heidi (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-23)
      <i>Introduction</i> - Maternal alloimmunization against human platelet antigen (HPA)-1a has been implied to mediate both reduced birth weight and chronic placental inflammation. Fetal growth restriction is associated with different types of chronic inflammation in the placenta, mainly chronic histiocytic intervillositis and chronic villitis. The aim of this prospective study was to do a systematic ...
    • Role of Laeverin in the pathophysiology of preeclampsia 

      Nystad, Mona (Doctoral thesis; Doktorgradsavhandling, 2018-05-11)
      Preeclampsia is a pregnancy-specific disease, affecting 5-10% of human pregnancies worldwide. It is defined as new-onset hypertension after 20 weeks of gestation with either proteinuria and/or organ failure. Laeverin is a membrane-bound aminopeptidase exclusively expressed in the placenta. Our previous studies revealed a significant upregulation of laeverin mRNA in preeclamptic placentas, building ...
