The extracellular lysophospholipase D autotaxin (ATX) and its product, lysophosphatidic acid, have diverse functions in development and cancer, but little is known about their functions in the immune system. Here we found that ATX had high expression in the high endothelial venules of lymphoid organs and was secreted. Chemokine-activated lymphocytes(More)
A region in the vicinity of D17Mit119 on mouse chromosome 17 harbors a susceptibility gene, designated as Ahl3, to age-related hearing loss (AHL). We produced congenic lines of C57BL/6 background that substituted regions around D17Mit119 with MSM-derived ones, and examined auditory brainstem response (ABR) thresholds for their hearing capacity at 6 and(More)
The H1N1 influenza A virus, which originated in swine, caused a global pandemic in 2009, and the highly pathogenic H5N1 avian influenza virus has also caused epidemics in Southeast Asia in recent years. Thus, the threat from influenza A remains a serious global health issue, and novel drugs that target these viruses are highly desirable. Influenza A RNA(More)
It has been shown that lysophosphatidic acid (LPA), a signaling phospholipid, induces neurite retraction and the formation of retraction fibers in young cortical neurons by actin rearrangement. This study examined the rearrangement of microtubules (MTs) during LPA-induced neurite remodeling by immunostaining with antibodies against several types of tubulin.(More)
Alpha-fetoprotein (AFP) is a fetal glycoprotein that is known as a biomarker for monitoring pregnancy in many mammalian species. However, characterization of AFP has not yet been undertaken in any cetacean species. Here, we purified AFP from the serum of fetal striped dolphin by chemical precipitation followed by a combination of immunoadsorbent column(More)
The purpose of this work is to estimate optimum surgical treatment of ranula according to the type of the lesion. Nine patients with ranula surgically treated between 1989 and 2000 were investigated retrospectively. Six patients had sublingual type ranula and three had submandibular type. In five cases including recurrence cases, the sublingual gland was(More)
BACKGROUND The pathogenesis of recurrent cholesteatoma can be roughly divided into residual lesions and re-retraction of the epithelium. To prevent both residual and re-retraction cholesteatoma, we performed canal wall down tympanoplasty with mastoid obliteration using the bone pate plate for canal wall reconstruction as a fundamental surgical treatment for(More)
OBJECTIVE In general, cholesteatoma tends to recur more frequently in children than in adults. This has been suggested to be due to immature Eustachian tube function, underdeveloped mastoid air cells, and subsequent repetitive otitis media in children. This study was undertaken to determine the characteristics of acquired cholesteatoma in children by(More)
A single radial immunodiffusion (SRID) assay and a chemiluminescent immunoassay (CLIA) were initially developed for alpha-fetoprotein (AFP) of the striped dolphin. Utilizing these developed assays, we investigated pregnancy-associated changes in the levels of AFP in the sera of fetuses and pregnant females of three dolphin species; samples were either(More)
BACKGROUND Differentiating Kawasaki disease (KD) from cervical lymphadenitis (CL) is clinically difficult but essential given that treatment and outcome differ significantly. Research on differentiation between KD and CL using ultrasound (US) and computed tomography (CT) is limited. The purpose of this study was to identify cervical US and CT findings that(More)
