Orexin neurons are exclusively localized in the lateral hypothalamic area and project their fibers to the entire central nervous system, including the histaminergic tuberomammillary nucleus (TMN). Dysfunction of the orexin system results in the sleep disorder narcolepsy, but the role of orexin in physiological sleep-wake regulation and the mechanisms(More)
Considerable evidence indicates that adenosine may be an endogenous somnogen, yet the mechanism through which it promotes sleep is unknown. Adenosine may act via A1 receptors to promote sleep, but an A2a receptor antagonist can block the sleep induced by prostaglandin D(2). We previously reported that prostaglandin D(2) activates sleep-promoting neurons of(More)
PURPOSE The aim of our study was to update the rate of severe complications following CT-guided needle biopsy in Japan via a mailed survey. MATERIALS AND METHODS Postal questionnaires regarding CT-guided needle biopsy were sent out to multiple hospitals in Japan. The questions regarded: the total number and duration of CT-guided lung biopsies performed at(More)
PURPOSE To identify patient characteristics and magnetic resonance (MR) imaging findings associated with subsequent hypervascularization in hypovascular nodules that show hypointensity on hepatobiliary phase gadoxetic acid-enhanced MR images in patients with chronic liver diseases. MATERIALS AND METHODS Institutional review board approval was obtained,(More)
The mutual phylogenetic relationships of dermatophytes of the genera Trichophyton, Microsporum, and Epidermophyton were demonstrated by using internal transcribed spacer 1 (ITS1) region ribosomal DNA sequences. Trichophyton spp. and Microsporum spp. form a cluster in the phylogenetic tree with Epidermophyton floccosum as an outgroup, and within this(More)
Using internal transcribed spacer 1 (ITS1) region ribosomal DNA sequences from 37 stock strains and clinical isolates provisionally termed Trichophyton mentagrophytes complex in Japan, we demonstrated the mutual phylogenetic relationships of these strains. Members of this complex were classified into 3 ITS1-homologous groups and 13 ITS1-identical groups by(More)
To evaluate the genetic homogeneity of Trichophyton mentagrophytes var. interdigitale, restriction enzyme analysis of mitochondrial(mt) DNA was performed on 29 isolates of T. mentagrophytes var. interdigitale isolated from Belgian or Indian patients with dermatophytosis. The restriction enzyme profiles of these mtDNAs were compared with those of the(More)
The pim-1 oncogene encodes a serine/threonine kinase (Pim-1) involved in the transduction of cytokine-triggered mitogenic signals. Pim-1 is unique in that it closely cooperates with c-Myc not only in oncogenesis, but also in apoptosis induction. However, the molecular basis of Pim-1 function remains poorly understood, largely because the downstream effector(More)
The efficacy of random amplification of polymorphic DNA (RAPD) analysis, a polymerase chain reaction (PCR)-based technology, as a tool for differentiation of several anthropophilic dermatophytes, that is, Trichophyton mentagrophytes var. interdigitale, T. rubrum and Epidermophyton floccosum, was examined. Total cellular DNA extracted by a mini-preparation(More)
We previously reported a conserved haplotype of HLA B52-DR2 and a significantly high frequency of the major histocompatibility complex (MHC) class I chain-related gene A (MICA) transmembrane-short tandem repeat (TM-STR) 6 allele in Japanese patients with ulcerative colitis (UC). To examine the predominance of the MICA TM-STR 6 allele as a marker of the(More)
