    • Using chemical reaction kinetics to predict optimal antibiotic treatment strategies 

      Abel zur Wiesch, Pia; Clarelli, Fabrizio; Cohen, Ted (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-01-06)
      Identifying optimal dosing of antibiotics has proven challenging—some antibiotics are most effective when they are administered periodically at high doses, while others work best when minimizing concentration fluctuations. Mechanistic explanations for why antibiotics differ in their optimal dosing are lacking, limiting our ability to predict optimal therapy and leading to long and costly experiments. ...
    • Hormonbehandling og hormonkonsentrasjon hos kvinner behandlet for eggstokkreft 

      Egeberg, Celine Victoria (Master thesis; Mastergradsoppgave, 2016-05-13)
      Epitelial eggstokkreft (EEK) er den 6. mest vanlige kreftformen blant norske kvinner. Det diagnostiseres ca. 450 nye tilfeller per år. Fem års overlevelse har økt og det har derfor vært viktig å se på langtidseffektene som påvirker kvinnene. Kvinnene kommer i en umiddelbar menopause etter kirurgisk fjerning av eggstokkene. Dette gjør også at de ofte opplever mer symptomer og plager enn kvinner som ...
