In this contribution, we have studied structural and photophysical properties of aggregated CdS quantum dots (QDs) capped with 2-mercaptoethanol in aqueous medium. The hydrodynamic diameter of the nanostructures in aqueous solution was found to be approximately 160 nm with the dynamic light scattering (DLS) technique, which is in close agreement with atomic force microscopy (AFM) studies (diame...
Murine models of bone marrow transplantation were used to study the mechanisms governing the activation of donor lymphocyte infusions (DLIs) manifesting as lymphohematopoietic graft-versus-host (LH-GVH) and graft-versus-leukemia (GVL) reactivities. We demonstrate here that established mixed chimerism influences the potency of DLI-mediated alloreactivity only in the MHC-mismatched but not MHC-ma...
The clinical success of allotransplantation and the shortage of donor organs have led to a proposal for the use of animal organs as alternative therapeutic materials for humans. In that regard, swine are preferable to non-human primates as a source of donor organs. While applications for clinical trials for xenotransplantation have not yet been received in Canada, several trials have already be...
Allogeneic bone marrow transplantation is an essential therapy for acquired aplastic anemia and prognosis has recently improved. However, engraftment failure and graft-versus-host disease are potential fatal complications. Various risk factors for poor prognosis have been identified, such as patient age and human-leukocyte antigen disparity, but the relationship between donor age and prognosis ...
Composite endpoints that not only encompass mortality and relapse, but other critical post-transplant events such as graft-versus-host disease, are being increasingly utilized to quantify survival without significant morbidity after allogeneic blood or marrow transplantation. High-dose, post-transplantation cyclophosphamide reduces severe graft-versus-host disease with allogeneic marrow transpl...
Xenotransplantation is a potential solution to the current donor shortage for solid organ transplantation. The transmission of infectious agents from donor organs or bone marrow to the recipient is a well-recognized phenomenon following allotransplantation. Thus the prospect of xenotransplantation raises the issue of xenozoonoses-i.e., the transmission of animal infections to the human host. An...
