Subnanometer Pd clusters stabilized within micelles of random copolymers were formed by direct immobilization of Pd(0) via ligand exchange. The clusters were estimated to contain approximately seven Pd atoms on average (cluster diameter approximately 0.7 nm). Several Pd-containing micelle morphologies could be obtained by polymer cross-linking. These(More)
Homogeneously alloyed bimetallic particles of AuPd with an average size of ca. 2 nm were successfully prepared by simultaneous sputter deposition of Au and Pd in an ionic liquid in the absence of any additional stabilizing agents. The chemical composition of the AuPd alloy was tunable depending on the area fraction of Au plates in the Au-Pd binary targets(More)
Anthracyclines are key drugs for the treatment of children with acute lymphoblastic leukemia (ALL). However, anthracyclines are known to induce QT prolongation, and life-threatening complications, such as torsades de pointe may also occur. To date, there have been no reports on the use of anthracyclines in patients with congenital long QT syndrome (LQTS).(More)
Multidrug-resistant Pseudomonas aeruginosa (MDRP) is a major problem among hospital-acquired infections. We had a one-month outbreak of this strain at a university hospital in Osaka, Japan, from May to June 2004. To determine the cause of the outbreak, we collected and analyzed epidemiological information about the patients from whom MDRP was isolated, and(More)
BACKGROUND Invasive fungal infections (IFIs) remain a major cause of infectious morality in neutropenic patients receiving chemotherapy or hematopoietic stem cell transplantation (HSCT). Micafungin exhibits broad antifungal activity against both Aspergillus and Candida species. We performed a retrospective study to determine the efficacy and safety of(More)
Anaplastic large cell lymphoma (ALCL) is chemosensitive, but recurrence is frequently observed. Allogeneic hematopoietic stem cell transplantation (HSCT) has recently been reported to be effective against recurrent disease, suggesting a graft-versus-lymphoma effect. We present a 3-year-old child with recurrent ALCL who underwent HSCT from an HLA-1-locus(More)
SUMMARY Retropharyngeal neuroblastoma is rare. We report a 3-month-old infant with retropharyngeal neuroblastoma presenting with airway compression, which had an unresectable localized tumor without N-myc amplification. He was promptly treated with chemotherapy, resulting in a dramatic resolution. Subsequently, he received no surgical intervention and is(More)
The prognosis of high-risk rhabdomyosarcoma (RMS) with metastatic or recurrent disease remains poor. We report a 6-year-old girl who successfully underwent allogeneic hematopoietic stem cell transplantation against recurrent metastatic alveolar RMS. The disease recurred at distant lymph node metastasis with bone marrow involvement. After chemotherapy and(More)
OBJECTIVE To determine the safety and efficacy of long-term use of mizoribine by undertaking a 3-year post-marketing surveillance study. METHODS Subjects were all lupus nephritis patients newly treated with mizoribine between 1 October 2003 and 30 September 2005 at contracted study sites. RESULTS Mizoribine was administered to 881 lupus nephritis(More)
