To investigate the pathobiological behaviors of gastric mixed-type (MT) carcinomas and gastric carcinogenesis, the clinicopathological characteristics of MT carcinomas were analyzed and compared with intestinal-type (IT) and diffuse-type (DT) carcinomas. The expression of Ki-67, caspase-3, p53, fragile histine triad (FHIT), maspin, extracellular matrix(More)
In the main olfactory bulb, activation of group I metabotropic glutamate receptors (mGluRs) by olfactory nerve stimulation generates slow (2 Hz) oscillations near the basal respiratory frequency. These oscillations arise in the glomerular layer and may be generated, in part, by the intrinsic neurons, the juxtaglomerular neurons. We investigated the(More)
Abnormal electrophysiological activity in the striatum, which receives dense innervation from the cerebral cortex, is believed to set the stage for the behavioral phenotype observed in Huntington's disease (HD), a neurodegenerative condition caused by mutation of the huntingtin (mhtt) protein. However, cortical involvement is far from clear. To determine(More)
The phosphatase and tensin homolog deleted on chromosome 10 (PTEN) tumor suppressor is a phosphatase that antagonizes the phosphoinositol-3-kinase/AKT signaling pathway and suppresses cell survival as well as cell proliferation. To investigate the molecular role of PTEN expression and mutation in colorectal carcinomas, we performed immunohistochemistry to(More)
AIM To investigate the mechanisms underlying the protective effects of sodium tanshinone IIA sulfonate (STS) in an ischemia-reperfusion (I/R)-induced rat myocardial injury model. METHODS Male SD rats were iv injected with STS, STS+LY294002 or saline (NS) for 15 d. Then the hearts were subjected to 30 min of global ischemia followed by 2 h of reperfusion.(More)
BACKGROUND Tumor metastasis depends on cell adhesion, motility and deformability, resulting from quantitative alterations and rearrangement of actin-related protein (Arp) 2 and 3. The aim of this study was to clarify the roles of both molecules in tumorigenesis and progression of gastric carcinomas. PATIENTS AND METHODS Immunohistochemistry (IHC) was(More)
ING4 (inhibitor of growth gene 4) is a new member of the ING gene family and is implicated in chromatin remodeling and repression of cell growth. In order to explore the roles of ING4 in head and neck squamous cell carcinoma (HNSCC), ING4 expression was assessed in 214 cases of HNSCC by immunohistochemistry using tissue microarray, and in three oral SCC(More)
To clarify the role of p33ING1b in tumorigenesis and progression of head and neck squamous cell carcinoma (HNSCC), we examined the expression and subcellular localization of p33ING1b in 214 HNSCC cases in parallel with 60 dysplasia samples and 48 normal epithelium samples by immunohistochemistry, and analyzed correlations of expression of p33ING1b in HNSCC(More)
OBJECTIVE To evaluate the feasibility of endometrial sampler Pipelle for endometrial histologic diagnosis. METHODS Using prospective and self-control methods, 200 patients with endometrial biopsy firstly used Pipelle endometrial sampler for endometrial tissue, then followed by diagnostic curettage, the same pathologist evaluated the specimen quality and(More)
Different cortical areas are organized into distinct intracortical subnetworks. The manner in which descending pathways from the entire cortex interact subcortically as a network remains unclear. We developed an open-access comprehensive mesoscale mouse cortico-striatal projectome: a detailed connectivity projection map from the entire cerebral cortex to(More)
