    Sammanfattning : Infertility is a worldwide problem and the main reason for the use of assisted reproductive technol- ogy (ART). In-vitro fertilization (IVF) is one ART treatment normally used, where the fertilization of oocytes occurs in vitro. LÄS MER

  3. 2. How does different fresh gas flows affect stress in rats during anaesthesia induction with sevoflurane in a chamber?

    Master-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Linda Klevestedt; [2023]
    Nyckelord :råtta; beteende; stress; anestesi; inhalationskammare; excitation; induktion; uppvakning; färskgasflöde; sevofluran;

    Sammanfattning : The rat is one of the most used laboratory animals in Europe today. When replacement of live animals in research is not feasible, the aim is to improve the welfare of those animals by reducing stress and suffering. LÄS MER
