    • Sport Plus the Shooting: An Examination of International Sporting Success and Event Hostship's Impact on the National Willingness to Fight 

      Storm, Rasmus K.; Jakobsen, Tor Georg; Jakobsen, Jo (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-09-08)
      Research has long aimed to identify the effects of international sporting success or event hostship on nations. Overall findings suggest that tangible benefits are marginal at best. Still, some studies find that sport may have significant intangible effects, such as bolstering (short-term) feelings of national pride or happiness. Following this strand of research, the present paper asks whether ...
    • Relevance of the bacteriophage adherence to mucus model for Pseudomonas aeruginosa phages 

      de Freitas Almeida, Gabriel Magno; Ravantti, Janne; Grdzelishvili, Nino; Kakabadze, Elene; Bakuradze, Nata; Javakhishvili, Elene; Megremis, Spyridon; Chanishvili, Nina; Papadopoulos, Nikolaos; Sundberg, Lotta-Riina (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-06-24)
      Pseudomonas aeruginosa infections are getting increasingly serious as antimicrobial resistance spreads. Phage therapy may be a solution to the problem, especially if improved by current advances on phage-host studies. As a mucosal pathogen, we hypothesize that P. aeruginosa and its phages are linked to the bacteriophage adherence to mucus (BAM) model. This means that phage-host interactions ...

      Cardiomyopathy syndrome (CMS) caused by piscine myocarditis virus (PMCV) is a severe cardiac disease in Atlantic salmon (Salmo salar) and one of the leading causes of morbidity and mortality in the Norwegian aquaculture industry. Previous research suggest a variation in individual susceptibility to develop severe disease, however the role of the immune response in determining individual outcome ...
    • Circadian coupling of mitochondria in a deep-diving mammal 

      Ciccone, Chiara; Kante, Fayiri; Folkow, Lars; Hazlerigg, David Grey; West, Alexander Christopher; Wood, Shona Hiedi (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-04-08)
      Regulation of mitochondrial oxidative phosphorylation is essential to match energy supply to changing cellular energy demands, and to cope with periods of hypoxia. Recent work implicates the circadian molecular clock in control of mitochondrial function and hypoxia sensing. Because diving mammals experience intermittent episodes of severe hypoxia, with diel patterning in dive depth and duration, ...
