Neuroblastoma, one of the most common pediatric solid tumors, is characterized by two extreme disease courses, spontaneous regression and life-threatening progression. Here, we conducted a genome-wide search for differences in DNA methylation that distinguish between neuroblastomas of the two types. Three CpG islands (CGI) and two groups of CGIs were found(More)
This report describes a case of Abernethy malformation associated with hepatopulmonary syndrome, which was resolved after shunt ligation. The clinical course indicated that hepatopulmonary syndrome can develop in Abernethy malformation in which liver function and portal pressure is normal, and liver transplantation is not the exclusive therapy for(More)
BACKGROUND/PURPOSE Congenital bronchial atresia (CBA) usually presents incidentally in asymptomatic young male adults but is rarely diagnosed in children. The aim of this study was to clarify the clinical characteristics of CBA in childhood and to describe the spectrum of this condition. METHODS The clinical features in 29 patients with CBA, aged from 1(More)
BACKGROUND Late-presenting congenital diaphragmatic hernia (CDH) is a rare subset of CDH, most of the information derived from small series or case reports. The aim of this study was to document the clinical manifestations of late-presenting CDH using a large multicenter database. METHODS Information about late-presenting CDH (diagnosed at later than 30(More)
It has been difficult to characterize murine bone marrow (BM)-derived mesenchymal progenitor cells (MPCs) because of contamination with hematopoietic cells. We took advantage of the rapid proliferation of MPCs after replating to enrich murine MPCs by transfection with a retroviral vector carrying both LacZ and the selective neomycin resistance (neoR) gene.(More)
OBJECTIVES To document outcome and to explore prognostic factors in fetal left congenital diaphragmatic hernia (CDH). METHODS This was a multicenter retrospective study of 109 patients with prenatally diagnosed isolated left CDH born between 2002 and 2007. The primary outcome was intact discharge, defined as discharge from hospital without major(More)
PURPOSE Although various urologic complications have been reported after abdominoperineal pull-through and posterior sagittal anorectoplasty for the treatment of high-type imperforate anus, reports regarding complications after laparoscopically assisted anorectoplasty (LAARP) are surprisingly rare. Here, we discuss the potential complications of LAARP. (More)
An accurate prenatal assessment of the patients’ severity is essential for the optimal treatment of individuals with congenital diaphragmatic hernia (CDH). The purpose of this study was to clarify the reliability of the lung to thorax transverse area ratio (L/T) as a prenatal predictive parameter. A multicenter retrospective cohort study was conducted on(More)
Cynomolgus monkey embryonic stem cell (cyESC)-derived in vivo hematopoiesis was examined in an allogeneic transplantation model. cyESCs were induced to differentiate into the putative hematopoietic precursors in vitro, and the cells were transplanted into the fetal cynomolgus liver at approximately the end of the first trimester (n = 3). Although(More)
This article presents a microscopic MR technique for imaging small mammalian fetuses in utero and in vivo which can be used as a tool for studying normal and abnormal development in small animal fetal models, for targeting in utero intervention in such models, and for following development serially. This new method is applied to a rat model of congenital(More)
