Do some patients benefit from an unrelated donor (URD) transplant because of a stronger graft-versus-leukemia (GVL) effect? We analyzed 4099 patients with acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), and chronic myeloid leukemia (CML) undergoing a myeloablative allogeneic hematopoietic cell transplantation (HCT) from an URD (8/8 human leukocyte antigen [HLA]-matched, n=941)...
The present study is a long-term review and follow-up on conclusions and recommendations on the role and contents of a User Requirements Specification Document (URD) from a previous in-depth case study. The follow-up comprises a succession of investigations and two case studies to explore the role and contents of a URD within systems development and assessment, thereby gradually extending and r...
Bone marrow transplantation (BMT) can cure patients with high-risk or recurrent acute lymphoblastic leukemia (ALL). Those lacking a related donor can receive either autologous or histocompatible unrelated donor (URD) marrow. Autotransplantation may result in higher risk of relapse, whereas URD allografts, although associated with serious posttransplant toxicities, may reduce relapse risk. Six y...
PURPOSE The study aimed to compare the outcomes of patients undergoing hematopoietic stem cell transplantation (HSCT) from partially matched related donors (PMRD) and unrelated donors (URD) for hematologic malignancies without the use of in vitro T cell depletion. EXPERIMENTAL DESIGN HSCT was done on 297 consecutive patients from URDs (n = 78) and PMRDs (n = 219) during the same time period. ...
BACKGROUND Opioids have been shown to affect learning and memory processes. Different protocols of morphine withdrawal can substantially vary in their success to prevent opioid induced impairments of cognitive performance. In the present study, we report the effects of single and repetitive ultra-rapid detoxification (URD) on spatial learning and memory in morphine addicted rats. METHODS Morp...
The gas-phase conformations of protonated uridine, [Urd+H](+), and its 2'-deoxy form, protonated 2'-deoxyuridine, [dUrd+H](+), have been examined in detail previously by infrared multiple photon dissociation action spectroscopy techniques. Both 2,4-dihydroxy tautomers and O4 protonated conformers of [Urd+H](+) and [dUrd+H](+) were found to coexist in the experiments with the 2,4-dihydroxy tauto...
The gas-phase conformations of protonated uridine, [Urd+H](+), and its modified form, protonated 2'-deoxyuridine, [dUrd+H](+), generated by electrospray ionization are investigated using infrared multiple photon dissociation (IRMPD) action spectroscopy techniques. IRMPD action spectra of [Urd+H](+) and [dUrd+H](+) are measured over the IR fingerprint and hydrogen-stretching regions. [Urd+H](+) ...
A correlation between endoplasmic reticulum (ER) stress and laxative effects was first reported in a constipation model treated with an aqueous extract of Liriope platyphylla (AEtLP) roots. To investigate the correlation between the laxative effect of uridine (Urd) and ER stress response, alterations in the key parameters for ER stress were measured in loperamide (Lop) induced constipation Spra...
We have studied the outcome of 211 consecutive unrelated donor (URD) bone marrow transplants (BMT) performed at the University of Minnesota (Minneapolis, MN) between May 1985 and December 1992. Ninety patients (43%) received marrow matched serologically at HLA A, B, and DR loci; 86 (41%) received marrow with a major and 32 (15%) marrow with a minor serologic mismatch at the HLA A or B locus. Mu...
Infectious complications are a major cause of morbidity and mortality after allogeneic bone marrow transplantation (BMT). We have evaluated the incidence of late infections (beyond day +50) in recipients of related (RD) and unrelated donor (URD) allogeneic BMT, factors associated with increased risks of infection, and the impact of the late infections on survival. Between 1989 and 1991, 249 pat...
