  1. 1. Heart preservation

    Författare :Guangqi Qin; Thoraxkirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : 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. LÄS MER

  3. 2. Intestinal preservation for transplantation: translational approaches

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

    Sammanfattning : 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.

  5. 4. Enhanced Energy Efficiency and Preservation of Historic Buildings : Methods and Tools for Modeling

    Författare :Torun Widström; Folke Björk; Carl-Eric Hagentoft; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; preservation; historic buildings; building simulation;

    Sammanfattning : As the environmental impacts of the energy usage of the world today becomes more and more evident, enhancement of energy performance of the already existing building stock becomes more urgent. Buildings belonging to the cultural heritage are often the ones that are most difficult to deal with in this context. LÄS MER
