Human chromosome 14q32.2 harbors the germline-derived primary DLK1-MEG3 intergenic differentially methylated region (IG-DMR) and the postfertilization-derived secondary MEG3-DMR, together with multiple imprinted genes. Although previous studies in cases with microdeletions and epimutations affecting both DMRs and paternal/maternal uniparental disomy 14-like(More)
Asian individuals have much lower incidences of prostate and breast cancer than populations from Western developed countries. They also consume a lower fat, higher fiber diet, with a large intake of phytoestrogens. These phytoestrogens may protect against hormone-dependent cancers and other diseases. Our study used established gas chromatography-mass(More)
OBJECTIVE One of the thyroid-specific transcription factors, thyroid transcription factor-2 (TTF-2), performs a crucial role in the development of the thyroid gland. We performed genetic analysis of the TITF2 gene (encoding TTF-2) in patients with thyroid dysgenesis. METHODS By direct sequencing of the PCR products of TITF2, we screened the genomic DNA(More)
BACKGROUND Although neurogenic inflammation via the activation of C fibers in the airway must have an important role in the pathogenesis of asthma, their regulatory mechanism remains uncertain. OBJECTIVE The pharmacological profiles of endogenous cannabinoid receptor agonists on the activation of C fibers in airway tissues were investigated and the(More)
BACKGROUND The dose of ciclosporine-A (CSA) for long-term treatment of nephrotic syndrome remains unclear due to the chronic nephrotoxicity of CSA. PATIENTS AND METHODS We examined 14 children with steroid-dependent nephrotic syndrome (SDNS) who showed signs of steroid toxicity and did not respond to cyclophosphamide. CSA was started at a dose between 2.0(More)
Cerebro-oculo-facio-skeletal (COFS) syndrome is an autosomal recessive inherited disorder characterized by congenital microcephaly, congenital cataracts and/or microphthalmia, arthrogryposis, severe developmental delay, severe postnatal growth failure and facial dysmorphism with prominent nasal root and/or overhanging upper lip. This syndrome is now(More)
Glucocorticoid treatment for steroid-dependent nephrotic syndrome (NS) is associated with severe adverse effects, such as bone fractures and epidural lipomatosis. Furthermore, a high trough level of cyclosporine (CsA) over an extended period of time is known to induce CsA nephropathy. We present a girl with steroid-dependent NS and steroid-induced vertebral(More)
We examined the effects of cannabinoid receptor agonists on various respiratory reactions induced by the activation of capsaicin-sensitive afferent sensory nerves (C-fibers). (R)-(+)-[2,3-dihydro-5-methyl-3-[(4-merpholino)methyl]pyrrolo-[1,2,3-de]-1,4-benzoxazin-6-yl](1-naphthyl)methanone (WIN 55212-2) dose-dependently inhibited electrical field(More)
The E2A-HLF fusion transcription factor generated by t(17;19)(q22;p13) translocation is found in a small subset of pro-B cell acute lymphoblastic leukemias (ALLs) and promotes leukemogenesis by substituting for the antiapoptotic function of cytokines. Here we show that t(17;19)+ ALL cells express Survivin at high levels and that a dominant negative mutant(More)
Sex differences are recognized in children's free drawings with respect to motifs, colors, figure compositions, and expression. Boys tend to draw mobile objects and mechanical objects with dark or cold colors and often use bird's-eye-view composition when they draw pictures, whereas girls like to draw human motifs (especially girls and women), flowers, and(More)
