      Gabrielsen, Mari; Ravna, aina westrheim; Kristiansen, kurt; Sylte, Ingebrigt (Journal article; Tidsskriftartikkel; Peer reviewed, 2011-06-14)
      The serotonin (5-HT) transporter (SERT) plays an important role in the termination of 5-HT-mediated neurotransmission by transporting 5-HT away from the synaptic cleft and into the presynaptic neuron. In addition, SERT is the main target for antidepressant drugs, including the selective serotonin reuptake inhibitors (SSRIs). The three-dimensional (3D) structure of SERT has not yet been determined, ...

      Climate change is a major challenge to Arctic and other Indigenous peoples, but not the only and often not the most pressing one. We propose re-framing the treatment of climate change in policy and research, to make sure health, poverty, education, cultural vitality, equity, justice, and other topics highlighted by the people themselves and not just climate science also get the attention they ...
    • The three Endonuclease III variants of Deinococcus radiodurans possess distinct and complementary DNA repair activities 

      Sarre, Aili; Stelter, Meike; Rollo, Filipe; De Bonis, Salvatore; Seck, Anna; Hognon, Cecilia; Ravanat, Jean-Luc; Monari, Antonio; Dehez, Francois; Moe, Elin; Timmins, Joanna (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-28)
      Endonuclease III (EndoIII) is a bifunctional DNA glycosylase that removes oxidized pyrimidines from DNA. The genome of Deinococcus radiodurans encodes for an unusually high number of DNA glycosylases, including three EndoIII enzymes (drEndoIII1-3). Here, we compare the properties of these enzymes to those of their well-studied homologues from E. coli and human. Our biochemical and mutational data, ...
    • Binding Specificity of ASHH2 CW Domain Toward H3K4me1 Ligand Is Coupled to Its Structural Stability Through Its α1-Helix 

      Bril'kov, Maxim; Dobrovolska, Olena; Ødegård-Fougner, Øyvind; Turcu, Diana Cornelia; Strømland, Øyvind; Underhaug, Jarl; Aasland, Rein; Halskau, Øyvind (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-13)
      The CW domain binds to histone tail modifications found in different protein families involved in epigenetic regulation and chromatin remodeling. CW domains recognize the methylation state of the fourth lysine on histone 3 and could, therefore, be viewed as a reader of epigenetic information. The specificity toward different methylation states such as me1, me2, or me3 depends on the particular ...
    • Monitoring bacterial community dynamics in a drinking water treatment plant: an integrative approach using metabarcoding and microbial indicators in large water volumes

      Kleiven, Eivind Flittie (Doctoral thesis; Doktorgradsavhandling, 2022-06-08)
      Population cycles in small rodents have attracted attention from ecologists for more than a century. This spectacular phenomenon is crucial for the functioning of many northern food-webs and has intrigued ecologist because of its lessons for general ecology. Knowledge about the rodent cycle has, however, been hampered by the lack of reliable monitoring methods both for rodents and some of their ...
    • For all audiences: Incorporating immature stages into standardised spider inventories has a major impact on the assessment of biodiversity patterns 

      Domènech, Marc; Wangensteen, Owen S.; Enguídanos, Alba; Malumbres-Olarte, Jagoba; Arnedo, Miquel A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-25)
      Although arthropods are the largest component of animal diversity, they are traditionally underrepresented in biological inventories and monitoring programmes. However, no biodiversity assessment can be considered informative without including them. Arthropod immature stages are often discarded during sorting, despite frequently representing more than half of the collected individuals. To date, ...
    • Cutoff Latitudes of Solar Proton Events Measured by GPS Satellites 

      van Hazendonk, Charlotte Maartje; Heino, Erkka Petteri; Jiggens, Piers T.A.; Taylor, Matthew G.G.T.; Partamies, Noora; Mulders, Hjalmar C. J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-15)
      Solar energetic particles (SEPs), one of the main causes of particle radiation in interplanetary space, can disrupt radio communication, induce spacecraft failures and change the heating and cooling rates in the atmosphere among others. To investigate the impact of SEPs and more specifically solar proton events (SPEs), we established a cutoff latitude database based on energetic particle data from ...
    • Evaluation of a Simple Clinical Language Paradigm With Respect to Sensory Independency, Functional Asymmetry, and Effective Connectivity 

      Rødland, Erik; Melleby, Kathrine Midgaard; Specht, Karsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-03)
      The present study replicates a known visual language paradigm, and extends it to a paradigm that is independent from the sensory modality of the stimuli and, hence, could be administered either visually or aurally, such that both patients with limited sight or hearing could be examined. The stimuli were simple sentences, but required the subject not only to understand the content of the sentence but ...

    • Kiselalger som fôrkomponent i laksefôr. Biokjemisk sammensetning og fettsyreprofil hos atlantisk laks (Salmo salar L.) fôret med ulike lipid- og proteinkilder 

      Heimland, Maria (Master thesis; Mastergradsoppgave, 2020-05-15)
      Det økende behovet for marine ressurser som ingrediens i fôr har ført til et søk etter nye ressurser, da dagens ressurser ikke lengre er bærekraftig. For å øke utbytte er det foreslått å rette søket lengre ned i næringskjeden. Marine kiselalger er et eksempel på slike organismer. Disse er ikke godt utnyttet i dag, hovedsakelig på grunn av manglende kunnskap rundt teknologi, samt forskning på hvilke ...
