To establish a more appropriate animal recipient for xenotransplantation, NOD/SCID/gamma(c)(null) mice double homozygous for the severe combined immunodeficiency (SCID) mutation and interleukin-2Rgamma (IL-2Rgamma) allelic mutation (gamma(c)(null)) were generated by 8 backcross matings of C57BL/6J-gamma(c)(null) mice and NOD/Shi-scid mice. When human CD34+(More)
Globoid cell leukodystrophy (GLD; also known as Krabbe disease) is an invariably fatal lysosomal storage disorder caused by mutations in the galactocerebrosidase (GALC) gene. Hematopoietic stem cell (HSC)-based gene therapy is being explored for GLD; however, we found that forced GALC expression was toxic to HSCs and early progenitors, highlighting the need(More)
Hyperinsulinism-hyperammonemia syndrome (HHS) is a recently identified genetic disorder characterized by hyperinsulinemic hypoglycemia with concomitant hyperammonemia. In patients with HHS, activating mutations in the glutamate dehydrogenase (GDH) gene have been identified. GDH is a key enzyme linking glutamate metabolism with the Krebs cycle and catalyzes(More)
PURPOSE The role of three-dimensional (3D) helical CT in the treatment planning of breast cancer was evaluated. METHODS Of 36 patients examined, 30 had invasive ductal carcinoma, three had invasive lobular carcinoma, one had DCIS, one had DCIS with minimal invasion, and 1 had Paget's disease. Patients were examined in the supine position. The whole breast(More)
Lifelong blood cell production is governed through the poorly understood integration of cell-intrinsic and -extrinsic control of hematopoietic stem cell (HSC) quiescence and activation. MicroRNAs (miRNAs) coordinately regulate multiple targets within signaling networks, making them attractive candidate HSC regulators. We report that miR-126, a miRNA(More)
From 1966 through 1988, 124 patients with non-Hodgkin's lymphoma of the Waldeyer's ring were treated. Seventy patients were male, and 54 were female. Age ranged from 5 to 81 years with a median value of 53 years. Pathological slides were reviewed and reclassified according to the Working Formulation. Diffuse large cell type was most common (53%). Since(More)
HAX1 was identified as the gene responsible for the autosomal recessive type of severe congenital neutropenia. However, the connection between mutations in the HAX1 gene and defective granulopoiesis in this disease has remained unclear, mainly due to the lack of a useful experimental model for this disease. In this study, we generated induced pluripotent(More)
Dynamic behaviors of liposomes caused by interactions between liposomal membranes and surfactant were studied by direct real-time observation by using high-intensity dark-field microscopy. Solubilization of liposomes by surfactants is thought to be a catastrophic event akin to the explosion of soap bubbles in the air; however, the actual process has not(More)
Hepatoblastoma is the most common malignant liver tumor in children. Recently, liver transplantation has been indicated for unresectable hepatoblastoma. We retrospectively reviewed 14 children with a diagnosis of hepatoblastoma who had undergone living-donor liver transplantation (LDLT) at Kyoto University Hospital. During the period from June 1990 to(More)
