Antibiotic uptake by cultured Atlantic cod leucocytes and effect on intracellular Francisella noatunensis subsp. noatunensis replication
(Peer reviewed; Journal article, 2014-02-04)The granuloma disease caused by Francisella noatunensis subsp. noatunensis in farmed Atlantic cod has not been successfully treated by use of antibacterials, even when antibacterial resistance testing indicates a sufficient ... -
Anticancer activity in Planctomycetes
(Peer reviewed; Journal article, 2019-01-07)There is a strong need to develop new drugs against many severe diseases. Therapy resistance is a major problem, for instance, in infectious diseases and cancer. Drug discovery has again turned to nature to search for ... -
Antiviral immune responses in lumpfish (Cyclopterus lumpus) - with emphasis on type I interferons
(Master thesis, 2021-06-01) -
Apparent availability of zinc, selenium and manganese as inorganic metal salts or organic forms in plant-based diets for Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2019-03)The composition of salmonid diets has changed from the use of mainly marine ingredients to increased use of plant ingredients, and this has an impact on the mineral content and availability. Minerals, like zinc (Zn), ... -
Application of CRISPR-based gene editing tools in Atlantic salmon
(Doctoral thesis, 2024-05-15)Atlantisk laks er den viktigaste arten i norsk havbruksnæring. Næringa i Noreg er i dag ramma av fleire berekraftsufordringar, til dømes genetisk innblanding av rømt laks, og spreiing av smittsame sjukdommar. Dette påverkar ... -
Application of in vitro transcribed and translated HIV-1 reverse transcriptase and integrase in protein-protein interaction studies
(Master thesis, 2000)Replication of the human immunodeficiency virus (HIV) necessitates the two viral enzymes reverse transcriptase (RT) and integrase (IN). These two proteins are found to associate in a large nucleoprotein complex called the ... -
Application of laboratory methods for understanding fish responses to black soldier fly (Hermetia illucens) based diets
(Journal article; Peer reviewed, 2022)A major challenge for development of sustainable aquafeeds is its dependence on fish meal and fish oil. Replacement with more sustainable, nutritious and safe ingredients is now a priority. Over the last years, among several ... -
Approaches to defining a planetary boundary for biodiversity
(Peer reviewed; Journal article, 2014-09)The idea that there is an identifiable set of boundaries, beyond which anthropogenic change will put the Earth system outside a safe operating space for humanity, is attracting interest in the scientific community and ... -
Approaches to pollen taxonomic harmonisation in Quaternary palynology
(Journal article; Peer reviewed, 2023)Pollen taxonomic harmonisation involves the standardisation of the nomenclature of pollen and fern spores with similar morphotypes at the determination level that is common to all grains or spores with that morphotype ... -
Aquaculture relevant stressors and their impacts on skin and wound healing in post-smolt Atlantic salmon (Salmo salar L.)
(Doctoral thesis, 2018-11-30)The work described in this thesis focuses on the response mechanisms in the skin of post-smolt Atlantic salmon (Salmo salar L.) under the following challenging conditions: <ul> i. The effect of high biomass and low specific ... -
Aquaculture-driven evolution of the salmon louse (Lepeophtheirus salmonis) mtDNA genome
(Master thesis, 2022-06-01)Widespread resistance towards pyrethroids, a pesticide that has been extensively used in salmonid aquaculture to control sea lice, is reported in the salmon louse (Lepeophtheirus salmonis). The resistance mechanism has ... -
Aquaculture-driven evolution of the salmon louse mtDNA genome
(Journal article; Peer reviewed, 2023)Resistance toward the antiparasitic pyrethroid, deltamethrin, is reported in the Atlantic salmon louse (Lepeophtheirus salmonis salmonis), a persistent ectoparasite of farmed and wild salmonids. The resistance mechanism ... -
Aquaculture-driven evolution: distribution of pyrethroid resistance in the salmon louse throughout the North Atlantic in the years 2000–2017
(Journal article; Peer reviewed, 2020)The parasitic salmon louse, and its documented resistance to chemotherapeutants, represents the most persistent environmental challenge to global salmonid aquaculture. We used a genetic marker associated with pyrethroid ... -
Aquaporin evolution in fishes
(Peer reviewed; Journal article, 2011-07-26)Aquaporins represent a primordial group of transmembrane solvent channels that have been documented throughout the living biota. This facet alone emphasizes the positive selection pressure for proteins associated with ... -
The Arabidopsis (ASHH2) CW domain binds monomethylated K4 of the histone H3 tail through conformational selection
(Journal article; Peer reviewed, 2020)Chromatin post‐translational modifications are thought to be important for epigenetic effects on gene expression. Methylation of histone N‐terminal tail lysine residues constitutes one of many such modifications, executed ... -
Archaeological bird remains from Norway as a means to identify long-term patterns in a Northern European avifauna
(Doctoral thesis, 2021-06-18)Birds are currently facing a biodiversity crisis. Seabirds, birds in agricultural landscapes, and montane birds are particularly vulnerable to extinction. Whilst their modern distributions are well studied, how past events ... -
The Arctic Mid-Ocean Ridge Vent Fields - A valuable Resource for Marine Bioprospecting?
(Doctoral thesis, 2016-05-25)The past decade the awareness for sustainability has come more and more into focus of society in terms of a need for eco-friendlier processes and renewable energies, new and better pharmaceuticals, and agricultural- and ... -
An Arctic natural oil seep investigated from space to the seafloor
(Journal article; Peer reviewed, 2023)Due to climate change, decreasing ice cover and increasing industrial activities, Arctic marine ecosystems are expected to face higher levels of anthropogenic stress. To sustain healthy and productive ocean ecosystems, it ... -
