  1. 16. Validation of a Next Generation Sequencing based method for chimerism analysis in clinical practice

    Kandidat-uppsats, Uppsala universitet/Institutionen för medicinsk cellbiologi

    Författare :Maria Högberg; [2022]
    Nyckelord :Devyser chimerism; fragment analysis; hematopoietic stem cell transplantation; short tandem repeats; indels;

    Sammanfattning : Hematopoietic stem cell transplantation (HSCT) is used to treat patient with hematological diseases such as leukemia and genetic conditions such as sickle cell anemia. After HSCT the patients are supervised for signs of relapse of disease or rejection of transplanted cells. This is done by using chimerism analysis. LÄS MER

  3. 17. The Effect of Residual Bacterial Products Associated to Root Canal Infection on Stem Cells from the Apical Papilla: Understanding Basis on Regenerative Endodontic Treatment

    Master-uppsats, Umeå universitet/Tandläkarutbildning

    Författare :Alhussan Sora; Abla Afnan; [2022]
    Nyckelord :SCAP; RTCA; regenerative endodontic; Inactivated bacteria;

    Sammanfattning : Background: The regenerative function of stem cells from the apical papilla (SCAPs) is affected by the presence of bacteria from infected root canals. Living microorganisms influence SCAP function but the effect of inactive bacteria and its components on SCAPs needs further investigation. LÄS MER

  4. 18. Injectable and shape-retaining collagen hydrogel, crosslinked using bio-orthogonal cycloaddition chemistry

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Murtaza Sharq; [2022]
    Nyckelord :Injectable and shape-retaining collagen hydrogel; crosslinked using bio-orthogonal cycloaddition chemistry; Injicerbara och formbevarande kollagenhydrogeler; tvärbundna med bio-ortagonal cykloadditionskemi;

    Sammanfattning : Under senaste decennierna, har intresset kring implantat från naturliga och syntetiska polymerer ökat markant i samband med en ökad marknadsefterfrågan på vävnadsdonationer. Detta har lett till efterforskningen av nya in-situ formerande geler med formbevarande egenskaper in-vivo. LÄS MER

  5. 19. Surface Guided Helical Tomotherapy for Total Marrow Irradiation

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Hedda Enocson; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Background: Total marrow irradiation (TMI) with helical tomotherapy treatment (HT-TMI) can be used as conditioning regimen for leukemia patients prior to stem cell transplantation by radiating the skeletal tissue. To ensure adequate dose coverage a margin is applied to the clinical target volume (CTV), i.e. planning target volume (PTV) margin. LÄS MER

  7. 20. Energy Landscapes for Early T Cell Development

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Yukun Cheng; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : T cell lineage development from an early thymic progenitor involves programmed shutoff of progenitor gene expression, upregulation of T cell specification genes, and proliferation. This biological system has been deeply studied and a gene regulatory network (GRN) that can accurately describe the system has been presented. LÄS MER
