      Schanche, Torstein Lindahl; Kondratyev, Timofey; Tveita, Torkjel (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-29)
      Rewarming by extracorporeal circulation (ECC) is the recommended treatment for accidental hypothermia patients with cardiac instability. Hypothermia, along with initiation of ECC, introduces major changes in fluid homeostasis and blood flow. Scientific data to recommend best practice use of ECC for rewarming these patients is lacking, and no current guidelines exist concerning the choice of priming ...

    • Impact of mucin on drug diffusion: Development of a straightforward in vitro method for the determination of drug diffusivity in the presence of mucin 

      Falavigna, Margherita; Stein, Paul C.; Flaten, Gøril Eide; Di Cagno, Massimiliano Pio (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-17)
      Mucosal drug delivery accounts for various administration routes (i.e., oral, vaginal, ocular, pulmonary, etc.) and offers a vast surface for the permeation of drugs. However, the mucus layer which shields and lubricates all mucosal tissues can compromise drugs from reaching the epithelial site, thus affecting their absorption and therapeutic effect. Therefore, the effect of the mucus layer on drug ...
