    • Investigations of immunogenic, allergenic and adjuvant properties of Cry1Ab protein after intragastric exposure in a food allergy model in mice 

      Andreassen, Monica; Bøhn, Thomas; Wikmark, Odd Gunnar; Bodin, Johanna; Traavik, Terje; Løvik, Martinus; Nygaard, Unni Cecilie (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-05-04)
      BACKGROUND In genetically modified (GM) crops there is a risk that the inserted genes may introduce new allergens and/or adjuvants into the food and feed chain. The MON810 maize, expressing the insecticidal Cry1Ab toxin, is grown in many countries worldwide. In animal models, intranasal and intraperitoneal immunisations with the purified Cry1Ab proteins have induced immune responses, and feeding ...

    • MicroRNAs in Daphnia magna identified and characterized by deep sequencing, genome mapping and manual curation 

      Coucheron, Dag H; Wojewodzic, Marcin; Bøhn, Thomas (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-04)
      MicroRNAs (miRNAs) are small non-coding RNAs that function in RNA silencing and post-transcriptional regulation of gene expression in most organisms. The water flea, <i>Daphnia magna</i> is a key model to study phenotypic, physiological and genomic responses to environmental cues and miRNAs can potentially mediate these responses. By using deep sequencing, genome mapping and manual curations, we ...

    • Miljørisikovurdering genmodifisert mais MON 89034 x NK603 fra Monsanto Company (EFSA/GMO/NL/2009/72). Uttalelse fra Faggruppe for genmodifiserte organismer Vitenskapskomiteen for mattrygghet 

      Sorteberg, Hilde-Gunn Opsahl; Bøhn, Thomas; Finne, Merethe Aasmo; Holck, Askild Lorentz; Klungland, Helge; Meadow, Richard; Myhr, Anne Ingeborg; Nerland, Audun Helge; Nes, Ingolf; Nielsen, Kaare Magne; Stabbetorp, Odd Egil; Vikse, Rose (Research report; Forskningsrapport, 2010-04-07)
      Helse- og miljørisikovurderingen av den insektresistente og herbicidtolerante maishybriden MON 89034 x NK603 (EFSA/GMO/NL/2009/72) fra Monsanto Company er utført av Faggruppe for genmodifiserte organismer i Vitenskapskomiteen for mattrygghet (VKM). VKM er bedt av Direktoratet for naturforvalting (DN) om å vurdere miljørisiko ved en eventuell godkjenning av maislinje MON 89034 x NK603 til dyrking og ...

    • Molecular characterization and phylogenetics of Fennoscandian cowpox virus isolates based on the p4c and atip genes 

      Okeke, Malachy Ifeanyi; Okoli, Arinze Stanley; Nilssen, Øivind; Moens, Ugo; Tryland, Morten; Bøhn, Thomas; Traavik, Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
      Background: Cowpox virus (CPXV), a rodent-borne Orthopoxvirus (OPV) that is indigenous to Eurasia can infect humans, cattle, felidae and other animals. Molecular characterization of CPXVs isolated from different geographic locations is important for the understanding of their biology, geographic distribution, classification and evolution. Our aim was to characterize CPXVs isolated from Fennoscandia ...

    • Retrospective evidence for a biological cost of vancomycin resistance determinants in the absence of glycopeptide selective pressures 

      Johnsen, Pål jarle; Townsend, JP; Bøhn, Thomas; Simonsen, Gunnar Skov; Sundsfjord, arnfinn; Nielsen, Kaare Magne (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      To estimate the relative fitness differences between glycopeptide-resistant Enterococcus faecium (GREF) and glycopeptide-susceptible E. faecium (GSEF) from yearly surveillance data on the occurrence of GREF in Danish poultry farm environments. A population genetic model was adapted to retrospectively estimate the biological fitness cost of acquired resistance. Maximization of a likelihood function ...

    • Salmon louse infestation levels on sea trout can be predicted from a hydrodynamic lice dispersal model 

      Bøhn, Thomas; Nilsen, Rune; Gjelland, Karl Øystein; Biuw, Martin; Primicerio, Raul; Karlsen, Ørjan; Serra Llinares, Rosa Maria (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-13)
      1. The abundance of the parasitic salmon louse has increased with the growth in aquaculture of salmonids in open net pens. This represents a threat to wild salmonid populations as well as a key limiting factor for salmon farming. The Norwegian ‘traffic light’ management system for salmon farming aims to increase aquaculture production while securing sustainable wild salmonid populations. However, ...

    • The Seralini affair: degeneration of Science to Re-Science? 

      Fagan, John; Traavik, Terje; Bøhn, Thomas (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-08-29)
      A paper reporting findings relevant to safety of the genetically modified (GM) maize NK603 and the herbicide Roundup (Séralini et al., Food Chem Toxicol. 50:4221–4231, 2012) was retracted against the wishes of the authors, and subsequently republished in another peer-reviewed journal (Séralini et al. Environ Sci Europe, doi:10.1186/s12302- 014-0014-5, 2014). These events exemplify a trend in which ...

    • Timing is everything: Survival of Atlantic salmon Salmo salar postsmolts during events of high salmon lice densities 

      Bøhn, Thomas; Gjelland, Karl Øystein; Serra Llinares, Rosa Maria; Finstad, Bengt; Primicerio, Raul; Nilsen, Rune; Karlsen, Ørjan; Sandvik, Anne Dagrun; Skilbrei, Ove Tommy; Elvik, Kristine Marit Schrøder; Skaala, Øystein; Bjørn, Pål Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-07)
      <ol> <li>Atlantic salmon in aquaculture act as reservoir hosts and vectors of parasites like salmon lice and this parasite is shown to harm wild salmonid populations.</li> <li>In this study, <i>n</i> = 29,817 tagged Atlantic salmon were studied in four release trials. Half of the released fish were given prophylactic treatment against lice, the other half represented sham control fish. We used ...
