    • Photophysiological cycles in Arctic krill are entrained by weak midday twilight during the Polar Night 

      Cohen, Jonathan H.; Last, Kim; Charpentier, Corie L.; Cottier, Finlo; Daase, Malin; Hobbs, Laura; Johnsen, Geir; Berge, Jørgen (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-19)
      Light plays a fundamental role in the ecology of organisms in nearly all habitats on Earth and is central for processes such as vision and the entrainment of the circadian clock. The poles represent extreme light regimes with an annual light cycle including periods of Midnight Sun and Polar Night. The Arctic Ocean extends to the North Pole, and marine light extremes reach their maximum extent in ...
    • A Green, Scalable, and Catalyst-Free One-Minute Synthesis of Quinoxalines 

      Elumalai, Vijayaragavan; Hansen, Jørn H (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-10)
      A highly efficient and catalyst-free protocol is reported for the synthesis of quinoxalines via the classical cyclocondensation reaction between aryldiamines and dicarbonyl compounds. Remarkably simple and green reaction conditions employing methanol as solvent afforded medium to excellent yield of quinoxalines after only one-minute reaction time at ambient temperature. The conditions allow at least ...
    • Drivers of Atmosphere-Ocean CO2 Flux in Northern Norwegian Fjords 

      Aalto, Nerea Johanna; Campbell, Karley; Eilertsen, Hans Christian; Bernstein, Hans Christopher (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-07)
      High-latitude fjords and continental shelves are shown to be sinks for atmospheric CO2, yet large spatial-temporal variability and poor regional coverage of sea-air CO2 flux data, especially from fjord systems, makes it difficult to scale our knowledge on how they contribute to atmospheric carbon regulation. The magnitude and seasonal variability of atmosphere-sea CO2 flux was investigated in ...
    • Female Mice Reaching Exceptionally High Old Age Have Preserved 20S Proteasome Activities 

      Martínez de Toda, Irene; Rattan, Suresh IS; De la Fuente, Mónica; Arranz, Lorena (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-31)
      Oxidized, damaged and misfolded proteins accumulate during aging and contribute to impaired cell function and tissue homeodynamics. Damaged proteins are degraded by cellular clearance mechanisms like the 20S proteasome. Aging relates to low 20S proteasome function, whereas long-lived species show high levels. However, contradictory results exist depending on the tissue or cell type and it is ...
    • Samisk kunst og norsk kunsthistorie: delvise forbindelser 

      Grini, Monica (Book; Bok, 2021)
      Hvordan er samisk kunst fremstilt i norsk kunsthistorie? Så enkelt og så komplekst er spørsmålet som driver denne boken frem. Utgangspunktet er en nysgjerrighet omkring hvordan samisk transnasjonalstatelighet slår ut i kunsthistorien; et spørsmål som ikke tidligere har blitt fremhevet som eksplisitt innfallsvinkel i undersøkelser av samisk kunst. Tilnærmingen hviler på en antagelse om at et ...

    • Irradiated tumor fibroblasts avoid immune recognition and retain immunosuppressive functions over natural killer cells 

      Yang, Nannan; Lode, Kristin; Berzaghi, Rodrigo; Islam, Md Ashraful; Martinez, Inigo Zubiavrre; Hellevik, Turid (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-22)
      Recent studies have demonstrated that radiotherapy is able to induce anti-tumor immune responses in addition to mediating direct cytotoxic effects. Cancer-associated fibroblasts (CAFs) are central constituents of the tumor stroma and participate actively in tumor immunoregulation. However, the capacity of CAFs to influence immune responses in the context of radiotherapy is still poorly understood. ...
