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 levels of the five methylated nucleosides pseudouridine (psi-Urd), 1-methyladenosine (1-MeAdo), 4 acetylcytidine (4-AcCyd), 1 methylinosine (1-Melno) and 7 methylguanosine (7-MeGuo) resulting from RNA degradation were examined in the urine of rheumatoid arthritis (RA) patients. Of these five, 1-MeAdo and psi-Urd were correlated with the active phase of the disease, while two others (4-AcCyd...
Addition of BrdUrd in combination with prednisolone to HSV1-transformed hamster embryo cells induces an alkaline phosphatase (AP). FdURd enhances, dThd reduces the inducing capacity of BrdUrd and prednisolone. Induction is prevented by addition of cycloheximide or of cytosine arabinoside. BrdUrd reduces transport and phosphorylation of exogenously applied labeled Urd, especially the amount of U...
Increased extracellular concentrations of uridine (Urd) have been reported to reduce, in vitro, azidothymidine (AZT)-induced inhibition of human granulocyte-macrophage progenitor cells without impairment of its antihuman immunodeficiency virus (HIV) activity. Because of the clinical toxicities associated with chronic Urd administration, the ability of benzylacyclouridine (BAU) to effect, in viv...
PURPOSE This study compared outcomes in children with acute leukemia who underwent transplantations with umbilical cord blood (UCB), bone marrow, or peripheral blood stem cells from a human leukocyte antigen (HLA)-matched related donor (MRD) or an unrelated donor (URD). METHODS This retrospective study included consecutive acute leukemia patients who underwent their first allogeneic hematopoi...
PURPOSE We evaluated the outcome of children with acute lymphoblastic leukemia (ALL) in second remission (2CR), comparing bone marrow transplantation (BMT) using either matched sibling donors or unrelated donors (URDs). PATIENTS AND METHODS A total of 65 patients, aged 2 months to 20 years at BMT, with ALL in 2CR underwent allogeneic BMT at seven Nordic centers during 1990 to 1997. Of the fir...
The ribonucleoside analogues (E)-5-(2-bromovinyl)uridine (5-BV-Urd) and 3'-spiro-(4'-amino-1',2'-oxathiole-2',2'-dioxide)-5-methyluridine (3'-AOD-5-MeUrd) emerged as potent and selective competitive inhibitors of mitochondrial thymidine kinase (TK)-2 with respect to thymidine (K(i)/K(m) values of 9.0 and 1.2 respectively). Cytosolic TK-1 did not show measurable affinity for these compounds. [(3...
PURPOSE OF REVIEW This review summarizes the state of the art of unrelated donor (URD) umbilical cord blood transplantation (UCBT) for the treatment of hematologic malignancies and discusses the current issues associated with the use of this hematopoietic stem cell (HSC) source. RECENT FINDINGS In contrast to the very high transplant-related mortality associated with the early experience of U...
Limited data are available for adults undergoing unrelated donor (URD) BMT for AML using chemotherapy-only preparative regimens. Previous studies incorporated irradiation, included adults and children, and excluded secondary leukemia. Herein we report long-term outcomes for adults with poor-prognostic AML receiving a novel regimen of busulfan (16 mg/kg), cytarabine (8,000 mg/m(2)), and cyclopho...
We assessed the combination of sirolimus and tacrolimus without methotrexate after myeloablative allogeneic stem cell transplantation from 53 matched related donors (MRDs) and 30 unrelated donors (URDs). All patients received cyclophosphamide and total body irradiation conditioning followed by transplantation of mobilized peripheral blood stem cells. The median time to neutrophil engraftment wa...
