We report 2 cases of plexiform angiomyxoid myofibroblastic tumor of the stomach, a tumor entity that has not been described previously. The patients were a 50-year-old man (case 1) and a 68-year-old man (case 2). In case 1, the patient presented with acute abdominal pain. The tumor in case 2 was incidentally found at laparoscopic cholecystectomy. Grossly,(More)
The authors report a case of the rhabdoid predisposition syndrome (RPS) secondary to a germline hSNF5/INI1 mutation, whose brain tumor was originally unclassified but finally diagnosed as an atypical teratoid/rhabdoid tumor (AT/RT) by molecular analysis. A 7-month-old infant presented with hydrocephalus secondary to a huge pineal tumor and subsequently(More)
Salt-inducible kinase 3 (SIK3), an AMP-activated protein kinase-related kinase, is induced in the murine liver after the consumption of a diet rich in fat, sucrose, and cholesterol. To examine whether SIK3 can modulate glucose and lipid metabolism in the liver, we analyzed phenotypes of SIK3-deficent mice. Sik3(-/-) mice have a malnourished the phenotype(More)
Although Japanese herbal medicines (JHMs) are widely used in Japan, only a few studies have investigated their effects on nonalcoholic steatohepatitis (NASH). In the present study, we examined the effect of 4 kinds of JHMs [sho-saiko-to (TJ-9), inchin-ko-to (TJ-135), juzen-taiho-to (TJ-48), and keishi-bukuryo-gan (TJ-25)] on a mouse model of NASH. Db/db(More)
BACKGROUND/PURPOSE Hepatocellular carcinomas (HCCs) commonly originate from pre-malignant lesions consisting of mature hepatocytes. However, recent studies have suggested that some HCCs emerge from hepatic stem/progenitor cells because stem/progenitor cell markers and cholangiocyte markers are found in these HCCs. At the same time, the expression of(More)
OBJECT Medulloblastoma is a malignant cerebellar tumor of childhood and is difficult to cure due to frequent cerebrospinal fluid dissemination. Amplification of the c-myc gene (4%) and messenger (mRNA) overexpression (50%) are known to be adverse prognostic indicators. Because mRNA overexpression cannot be explained by gene amplification alone, mechanisms(More)
BACKGROUND AND AIMS Some follow-up studies of large regenerative nodules (LRNs) and dysplastic nodules (DNs) were reported previously. However, the pre-malignant potentiality of LRNs has remained controversial up to now. No LRNs showed malignant transformation in our previous study. We aimed to evaluate the pre-malignant potentiality of LRNs and DNs with a(More)
The expression of the alpha and beta isoforms of phosphatidylinositol transfer protein (PI-TP alpha and PI-TP beta) in the adult rat brain was examined by in situ hybridization analysis with isoform-specific RNA probes. PI-TP alpha mRNA was detected in rather restricted regions of the brain whereas PI-TP beta mRNA was widely distributed in the brain. PI-TP(More)
Nonalcoholic steatohepatitis (NASH) is a liver disease associated with metabolic syndrome. The aim of this work was to examine whether eucalyptus (Eucalyptus globulus) leaf extract (ELE) and banaba (Lagerstroemia speciosa L.) leaf extract (BLE) inhibited NASH induced by excessive ingestion of fructose in rats. Wistar rats were divided into four groups(More)
A 67-year-old Japanese woman with liver cirrhosis was affected by an unusual acute progressive encephalopathy, presenting mental confusion and slurred speech as its initial symptoms. She died in profound coma, following the entire course of 17 days. Autopsy disclosed bilateral symmetrical, widespread, edematous and necrotic lesions, their centers being(More)
