  2. 1. Heart preservation

    Author : Guangqi Qin; Thoraxkirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : In clinical transplantation today, the donor heart is preserved with cold ischemic storage that gives safe preservation for 4 hours. Non-ischemic perfusion preservation is able to preserve the donor heart for 24 hours in pre-clinical studies. The aim of this thesis is to investigate: 1. READ MORE

  4. 2. Intestinal preservation for transplantation: translational approaches

    Author : John M. Söfteland; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intestinal transplantation; intestinal preservation; apoptosis; tight junction; luminal preservation;

    Abstract : Background: Intestinal preservation injury (IPI) may result in various degrees of mucosal damage, which may later favor bacterial translocation, post-reperfusion syndrome, and upregulation of alloreactivity. Experimental evidence suggests that combining vascular perfusion and cold storage with luminal interventions using polyethylene glycol (PEG) solutions may mitigate the mucosal damage and extend the safe storage time.
