Fourteen donors were given recombinant G-CSF to mobilize progenitor cells. Circulating CD34+ cells were monitored daily and leukapheresis was performed at 3-5 days when the level exceeded 20 x 10(6)/L. Monitoring of CD34+ cells collected at intervals during apheresis gave results within 20 min. Yields of 2.6-7.4 x 10(6) per kg recipient body weight were(More)
Twenty-six patients with haematological malignancy received cryopreserved but otherwise unmanipulated blood cell transplants (BCT) from five- or six-antigen matched siblings in whom progenitor cells had been mobilized by G-CSF. Outcomes were compared with a historical control group of 26 BMT patients matched for age and disease status. Granulocyte counts(More)
The study purpose was to determine if G-CSF plus dose-intensive cyclophosphamide 5.25 g/m2, etoposide 1.05 g/m2 and cisplatin 105 mg/m2 (DICEP) results in superior autologous blood stem cell mobilization (BSCM) than less intensive chemotherapy. From January 1993 until May 1997, 152 consecutive patients with non-Hodgkin's lymphoma (n = 55), breast cancer (n(More)
Yersinia enterocolitica is a bacterium capable of growth at 4 degrees C in donated blood and has been responsible for many deaths following transfusion. Interaction of Y. enterocolitica with blood cells is of interest in understanding the mechanisms of survival and growth in blood. The closely related organism Y. pseudotuberculosis is known to invade(More)
Autoimmune lymphoproliferative syndrome (ALPS) is a rare, newly recognized, chronic lymphoproliferative disorder in children and is characterized by lymphadenopathy, splenomegaly, pancytopenia, autoimmune phenomena and expansion of double-negative (DN) T lymphocytes (TCR alpha beta+, CD4-, CD8-). Defective lymphocyte apoptosis caused by mutations of the Fas(More)
BACKGROUND Distinction between 2 forms of inflammatory bowel disease (IBD), ulcerative colitis (UC) and Crohn's disease (CD), can be challenging. Aberrant mucosal immunity suggests that CD is a T helper type 1 cell (Th1)-driven disease, whereas UC as Th2-driven response. However, whether this paradigm truly distinguishes CD from UC is controversial. We(More)
Reoviruses infect cells that manifest an activated Ras-signaling pathway, and have been shown to effectively destroy many different types of neoplastic cells, including those derived from brain, breast, colon, ovaries, and prostate. In this study, we investigated the reovirus as a potential therapeutic agent against lymphoid malignancies. A total of 9(More)
Laser capture microdissection (LCM) has recently been identified as a quick, simple, and effective method by which microdissection of complex tissue specimens for molecular analysis can be routinely performed. Assessment of gene copy number by fluorescence in situ hybridization (FISH) is useful for the analysis of molecular genetic alterations in cancer.(More)
Reovirus is a nonattenuated double-stranded RNA virus that exploits aberrant signaling pathways allowing selective cytotoxicity against multiple cancer histologies. The use of reovirus as a potential treatment modality for prostate cancer has not previously been described, and in this study evidence of in vitro and in vivo activity against prostate cancer(More)
