Agonistic and potentiating effects of perfluoroalkyl substances (PFAS) on the Atlantic cod (Gadus morhua) peroxisome proliferator-activated receptors (Ppars)
(Journal article; Peer reviewed, 2022)Toxicity mediated by per- and polyfluoroalkyl substances (PFAS), and especially perfluoroalkyl acids (PFAAs), has been linked to activation of peroxisome proliferator-activated receptors (Ppar) in many vertebrates. Here, ... -
Aktivering av aryl hydrokarbonreseptor (Ahr)-signalveien og lokalisering av ahr genuttrykking i tidlige livsstadier til Atlanterhavstorsk (Gadus morhua) etter eksponering for råolje

Algal toxin azaspiracid-1 induces early neuronal differentiation and alters peripherin isoform stoichiometry
(Peer reviewed; Journal article, 2015-12-14)Azaspiracid-1 is an algal toxin that accumulates in edible mussels, and ingestion may result in human illness as manifested by vomiting and diarrhoea. When injected into mice, it causes neurotoxicological symptoms and ... -
Alginate and tunicate nanocellulose composite microbeads – Preparation, characterization and cell encapsulation
(Journal article; Peer reviewed, 2022)Alginate has been used for decades for cell encapsulation. Cellulose nanofibrils (CNF) from tunicates are desirable in biomedicine due to high molecular weight, purity, crystallinity, and sustainable production. We prepared ... -
Alien plants, animals, fungi and algae in Norway:an inventory of neobiota
(Peer reviewed; Journal article, 2019-08-03)We present the results of an inventory and status assessment of alien species in Norway. The inventory covered all known multicellular neobiota, 2496 in total, 1039 of which were classified as naturalised. The latter ... -
Alien species in Norway: Results from quantitative ecological impact assessments
(Journal article, 2020)1. Due to globalisation, trade and transport, the spread of alien species is increasing dramatically. Some alien species become ecologically harmful by threatening native biota. This can lead to irreversible changes in ... -
Amino Acid Carriers of the Solute Carrier Families 7 (SLC7) and 38 (SLC38) Are Involved in Leucine Sensing in the Brain of Atlantic Salmon (Salmo salar)
(Journal article; Peer reviewed, 2021)Sensing of amino acids in fish brain, especially branched-chain amino acids (BCAA) like leucine, is involved in regulation of feed intake through different mechanisms. However, there is limited information regarding the ... -
Ammonia oxidation and oxygen consumption rate measurements in RAS at different alkalinities
(Master thesis, 2023-06-02)The need for environmentally friendly sustainable nutritious food has never been more imminent than today, with a need to increase the world´s animal-based food supply by 70% by 2050. By simply increasing the number of ... -
Ammonia-eliminating potential of Gracilaria sp. And zeolite: a preliminary study of the efficient ammonia eliminator in aquatic environment
(Peer reviewed; Journal article, 2019-02-01)High density and high feeding volume are regarded as factors causing huge accumulations of Total Ammonia Nitrogen (TAN) in an aquaculture system. An uncontrolled TAN concentration in an aquaculture system can pose a threat ... -
An amphipathic helix in Brl1 is required for nuclear pore complex biogenesis in S. cerevisiae
(Journal article; Peer reviewed, 2022)The nuclear pore complex (NPC) is the central portal for macromolecular exchange between the nucleus and cytoplasm. In all eukaryotes, NPCs assemble into an intact nuclear envelope (NE) during interphase, but the process ... -

Anaesthesia of farmed fish with special empasis on atlantic cod (Gadus morhua) and atlantic habibut (Hippoglossus hippoglossus)
(Doctoral thesis, 2011-03-23)During the life cycle as farmed animals there are numerous situations where fish are subjected to handling and confinement. Netting, weighing, sorting, vaccination, transport and, at the end, slaughter are common events ... -
Analyse av biomarkører i leverprøver fra atlanterhavstorsk (Gadus morhua) benyttet i et burforsøk i Kollevåg, Askøy kommune
(Master thesis, 2017-09-05)Kollevåg er et etablert friluftsområde på vestsiden av Askøy i Hordaland. Området har også i tidsperioden 1930-1975 fungert som et avfallsdeponi for usortert avfall for innbyggere i Bergen kommune. Avfallet ble dumpet på ... -
