PURPOSE To measure both volume and signal intensity of the fetal lung at magnetic resonance (MR) imaging and to evaluate the clinical use of this method to predict fetal pulmonary hypoplasia. MATERIALS AND METHODS A total of 87 fetuses evaluated with MR imaging at 24-39 weeks of gestation were classified into a control group with good respiratory outcome(More)
OBJECTIVE To prepare nomograms for normal fetal lung volume using three-dimensional ultrasonography and to evaluate the possibility of clinical applications of this procedure. METHODS One hundred twenty-five healthy neonates with birth weights within +/-1.5 SD (group A), 9 neonates with intrauterine growth restriction (birth weight less than -1.5 SD) but(More)
We isolated Nd1, a novel kelch family gene that encodes two forms of proteins, Nd1-L and Nd1-S. Nd1-L contains a BTB/POZ domain in its N terminus and six kelch repeats in the C terminus. Nd1-S has the BTB/POZ domain but lacks the six kelch repeats. Nd1-L but not Nd1-S mRNA is detected ubiquitously in normal mouse tissues. Nd1-L and Nd1-S proteins can form a(More)
This study compared subsequent pregnancy outcome in patients with complete and partial hydatidiform moles. Among 1052 patients with molar pregnancy (complete mole, 801; partial mole, 251) monitored at Chiba University Hospital between 1981 and 1999, 891 patients (84.7%) had spontaneous resolution of human chorionic gonadotrophin (HCG) after mole evacuation,(More)
The Ncx/Hox11L.1 gene, a member of the Hox11 homeobox gene family, is mainly expressed in neural crest-derived tissues. To elucidate the role of Ncx/Hox11L.1, the gene has been inactivated in embryonic stem cells by homologous recombination. The homozygous mutant mice were viable. These mice developed megacolon with enteric ganglia by age 3-5 wk.(More)
OBJECTIVE To evaluate the efficacy of adjuvant hysterectomy with chemotherapy for women with low-risk gestational trophoblastic disease. METHODS One hundred fifteen consecutive Japanese women (16-52 years old) with low-risk gestational trophoblastic disease (46 with metastatic disease and 69 without) were treated initially with single-agent chemotherapy(More)
Ewing's sarcoma of the bone is a malignant bone tumor occurring mostly in adolescence and was considered to have poor prognosis. With recent advances in multi-agent combined chemotherapy, prognosis has improved, and more patients with primary lesions in the pelvis opt for limb-saving surgeries. In the present case, Ewing's sarcoma in the left pelvis was(More)
 We have isolated the murine homeobox gene (Ncx) that belong to a Hox11 gene family. Expression of the Ncx gene was analyzed in total RNAs from embryos by reverse transcribed polymerase chain reaction (RT-PCR). The mRNA was detected in embryos after 9.5 days of embryogenesis (E9.5) and was maximal at E12.5. The RT-PCR also detected the message in total RNAs(More)
Clinical guidelines for obstetrical practice were first published by the Japan Society of Obstetrics and Gynecology (JSOG) and the Japan Association of Obstetricians and Gynecologists (JAOG) in 2008, and a revised version was published in 2011. The aims of this publication include the determination of current standard care practices for pregnant women in(More)
BACKGROUND: The aim of this population-based retrospective study was to evaluate the trend in the incidence of molar pregnancy. METHODS: Questionnaires about the occurrence of hydatidiform mole were mailed to all clinics and hospitals in Chiba Prefecture between 1974 and 2000. The diagnosis of hydatidiform mole was based on the post-operative morphological(More)
