Cbfa1, a transcription factor that belongs to the runt-domain gene family, plays an essential role in osteogenesis. Cbfa1-deficient mice completely lacked both intramembranous and endochondral ossification, owing to the maturational arrest of osteoblasts, indicating that Cbfa1 has a fundamental role in osteoblast differentiation. However, Cbfa1 was also(More)
BACKGROUND This study examined the clinical value of intraoperative peritoneal lavage for cytological examination in patients with gastric cancer. Peritoneal dissemination is the most frequent mode of recurrence for this tumor. METHODS A retrospective of lavage findings, other factors, and outcome was performed in 1,297 patients with gastric cancer who(More)
We have identified the lymphocyte semaphorin CD100/Sema4D as a CD40-inducible molecule by subtractive cDNA cloning. CD100 stimulation significantly enhanced the effects of CD40 on B cell responses. Administration of soluble CD100 markedly accelerated in vivo antigen-specific antibody responses. CD100 receptors with different binding affinities were detected(More)
The class IV semaphorin CD100/Sema4D differentially utilizes two distinct receptors: plexin-B1 in nonlymphoid tissues, such as brain and kidney, and CD72 in lymphoid tissues. We have generated CD100-deficient mice and demonstrated that they have functional defects in their immune system, without apparent abnormalities in other tissues. The number of CD5(+)(More)
OBJECTIVE The aim of this study was to elucidate the detail profiles of circulating osteoprotegerin (OPG) and soluble receptor activator of nuclear factor kappaB ligand (sRANKL) in post-menopausal women. METHODS Eighty Japanese post-menopausal women were enrolled in this cross-sectional study. Circulating OPG and free fraction of sRANKL (free sRANKL),(More)
Osteopontin (Opn) and polyoma enhancer-binding protein (PEBP) 2alphaA/core binding factor (CBFA) 1 have been suggested to play important roles in ossification. The overlapping localization of opn and PEBP2alphaA/CBFA1 mRNA, and the marked decrease of opn mRNA expression in PEBP2alphaA knockout mice, indicated that the transcription of opn gene was(More)
Among the cases of ruptured aneurysms we have handled, some patients have rebled before surgery was performed. In this study, we examine the factors that contribute to the rerupture of cerebral aneurysms in the acute stage and suggest measures to prevent rerupture prior to surgery. We have encountered 32 cases of rebleeding prior to surgery. The rebleeding(More)
The authors report eight cases of trigeminal neurinoma managed over the past 13 years with radical resection at a single-stage operation. Three patients were male and five were female, ranging in age from 25 to 56 years (mean 41.5 years). One had von Recklinghausen's disease. The tumors were located mainly within the middle fossa in two cases and within the(More)
OBJECTIVE AND IMPORTANCE The occurrence of spontaneous spinal subarachnoid hematoma of unknown pathogenesis is extremely rare. In the cases reported to date, the hematoma, located dorsal to the spinal cord (dorsal type), has caused paraplegia and has required emergency surgical intervention. CLINICAL PRESENTATION We examined two patients who sustained(More)
PURPOSE Our goal was to analyze the anatomic similarity between the duplicated middle cerebral artery (MCA) and the accessory MCA and their relationship to the early branches of the MCA. METHODS We reviewed stereoscopic angiograms of duplicated MCAs in four patients and accessory MCAs in four patients with reference to the origin, size, and cortical(More)
