The modeling and remodeling of bone requires activation and polarization of osteoclasts, achieved by reorganization of the cytoskeleton. Members of the Rho subfamily of small GTPases, including Cdc42, are known regulators of cytoskeletal components, but the role of these proteins in bone physiology and pathophysiology remains unclear. Here, we examined(More)
We report a novel mutation of tau (L266V missense mutation in exon 9) which may cause a type of familial frontotemporal dementia. The brain of a patient showed Pick body-like inclusions and unique tau-positive, argyrophilic astrocytes with stout filaments and naked, round, or irregular argyrophilic inclusions with deposits of both three-repeat and(More)
BACKGROUND Some patients with hypertrophic cardiomyopathy (HCM) develop left ventricular (LV) wall thinning associated with LV dilatation and systolic dysfunction. Recently, matrix metalloproteinases (MMPs) and tissue inhibitors of MMPs (TIMPs) were reported to be involved in ventricular remodeling, however, little is known about MMPs and TIMPs in patients(More)
We have reported that the protein-protein interaction between UDP-glucuronosyltransferase (UGT) 2B7 and cytochrome P450 3A4 (CYP3A4) alters UGT2B7 function. However, the domain(s) involved in the interaction are largely unknown. To address this issue, we examined in more detail the CYP3A4-UGT2B7 association by means of immunoprecipitation, overlay assay,(More)
In Alzheimer's disease (AD), amyloid-β (Aβ) peptides accumulate in the brain in different forms, including fibrils and oligomers. Recently, we established three distinct conformation-dependent human single-chain Fv (scFv) antibodies, including B6 scFv, which bound to Aβ42 fibril but not to soluble-form Aβ, inhibiting Aβ42 fibril formation. In this study, we(More)
OBJECTIVE The aim of this study was to clarify characteristics of post-encephalopathic epilepsy (PEE) in children after acute encephalopathy with biphasic seizures and late reduced diffusion (AESD), paying particular attention to precise diagnosis of seizure types. METHODS Among 262 children with acute encephalopathy/encephalitis registered in a database(More)
BACKGROUND Rectal carcinoids comprise only about 1% of all anorectal neoplasms. In addition, ganglioneuroma of the gastrointestinal tract is a rare tumor composed ganglion cells, nerve fibers, and supporting cells. Multiple carcinoid tumors with diffuse ganglioneuromatosis limited to the rectum are quite unusual. CASE PRESENTATION A 69-year-old man was(More)
The Lutheran glycoprotein (Lu), also known as basal cell adhesion molecule (B-CAM), is an Ig superfamily (IgSF) transmembrane receptor for laminin α5. Although Lu is not present in normal hepatocytes, its expression is significantly increased in hepatocellular carcinoma (HCC). In this study, we isolated thirteen phage antibodies to Lu from a phage library(More)
OBJECTIVE The aim of this study was to clarify the characteristics of paroxysmal nonepileptic events (PNEs) suspected as being epileptic seizures by families of children with epilepsy. METHODS The video-EEG (vEEG) recordings of habitual paroxysmal events in children with epilepsy at Nagoya University Hospital between October 2006 and January 2016 were(More)
BACKGROUND AND PURPOSE West syndrome is an epileptic encephalopathy characterized by epileptic spasms, a specific pattern on electroencephalography of hypsarrhythmia, and developmental regression. Our aim was to assess white matter abnormalities in West syndrome of unknown etiology. We hypothesized that diffusion tensor imaging reveals white matter(More)
