The chemical structure of 1 was elucidated by spectroscopic experiments, including 1D and 2D NMR and HRESIMS analysis. Compound 1 is a lipoamino acid, consisting of a C<sub>12</sub> fatty acid anchored to the amino acid arginine. The bioactivity of 1 ...

    • Dendrobeaniamine A, a new alkaloid from the Arctic marine bryozoan Dendrobeania murrayana 

      Michael Siranjeevi, Raja Priyanka Mary (Conference object; Konferansebidrag, 2019)
      Chemistry guided purification of the organic extract of the Arctic marine bryozoan <i>Dendrobeania murrayana</i> yielded one new compound, Dendrobeaniamine A, and it was present in abundant amounts in the organic extract. Dendrobeaniamine A is a fusion of long chain aliphatic fatty acid and the cationic amino acid residue arginine.The bioactivity and natural function of this compound thus remain to ...

Seal and/or krill oil intended for human consumption might be included but in separate chapters. EU’s hygiene regulations for the ...

    • Detection of specific Atlantic salmon antibodies against salmonid alphavirus using a bead-based immunoassay 

      Teige, Lena Hammerlund; Aksnes, Ida; Røsæg, Magnus Vikan; Jensen, Ingvill; Jørgensen, Jorunn; Sindre, Hilde; Collins, Catherine; Collet, Bertrand; Rimstad, Espen; Dahle, Maria; Boysen, Preben (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-30)
      Salmonid alphavirus (SAV) is the etiological cause of pancreas disease (PD) in Atlantic salmon (<i>Salmo salar</i>). Several vaccines against SAV are in use, but PD still cause significant mortality and concern in European aquaculture, raising the need for optimal tools to monitor SAV immunity. To monitor and control the distribution of PD in Norway, all salmonid farms are regularly screened for SAV ...

      How long a tourist stays in a host country acts as an indicator of tourism industry’s contribution towards the national economy. The purpose of this study is to examine how socio-demographic characteristics of international tourists, their travelling purpose, tourism products and characteristics of the destination influence the length of stay in Norway, by estimating a parametric survival model. ...

    • Determination of pH in pre rigor fish muscle - method matters 

      Skjold, Vetle; Joensen, Joan Karl; Esaiassen, Margrethe; Olsen, Ragnar Ludvig (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-06)
      The determination of post mortem muscle pH are often carried out in studies on how pre-slaughter handling influences the development of rigor mortis and the quality of the fish products. The analysis might be performed by inserting a pH-electrode into the intact flesh or using a suspension containing a minced muscle sample. Although it has been known for a long time that mincing muscle tissue ...

      Spring viremia of carp virus (SVCV) can cause high mortality of fish. The aim of this study was to investigate the effects of Lactobacillus rhamnosus GCC-3 exopolysaccharides (GCC-3 EPS) on zebrafish (Danio rerio) infected with SVCV and elucidate the underlying mechanisms. Zebrafish were fed with a control diet or diet supplemented with 0.5% and 1% of GCC-3 EPS for 2 weeks. The results showed ...

      Jensen, Ingvill; Overrein, Mathias; Fredriksen, Børge Nilsen; Strandskog, Guro; Seternes, Tore (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-18)
      In today's aquaculture of Atlantic salmon (<i>Salmo salar</i> L.), a majority of viral disease outbreaks occur after seawater transfer. A relevant question is how the parr–smolt transformation influences the efficacy of viral vaccines and the innate resistance against viral diseases. In this study, vaccinated and unvaccinated A. salmon parr were exposed to different photoperiodic regimens (1‐, 3‐ ...

    • Different types of intuition at the workplace: an integrative review 

      Svenson, Frithiof; Pietrzak, Piotr; Launer, Markus A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-16)
      To make good decisions, employees must manage their own intuitions and be able to anticipate decision-making in their work environment. How well this is accomplished has significant consequences for the workplace. A closer examination indicates that individuals utilize various types of intuition. People’s work context is frequently omitted from studies on the use of intuition, resulting in a ...

    • Disentangling the influence of knowledge on attribute non-attendance 

      Sandorf, Erlend Dancke; Campbell, Danny; Hanley, Nick (Journal article; Tidsskriftartikkel, 2016-09-22)
      We seek to disentangle the effect of knowledge about an environmental good on respondents' propensity to ignore one or more attributes on the choice cards in a discrete choice experiment eliciting people's preferences for increased protection of cold-water corals in Norway. We hypothesize that a respondent's level of knowledge influences the degree to which she ignores attributes. Respondents ...
