We have designed and implemented a virtual machine monitor that virtualizes a sharedmemory multi-processor machine on a commodity cluster. This functionality greatly simplifies utilization of commodity clusters. For example, it enables parallel applications for sharedmemory multi-processor systems to run on clusters without any change of the applications.(More)
Clinicopathologic features and postoperative outcomes were investigated for patients who underwent curative surgery for biliary marker (CK7 and CK19)-positive hepatocellular carcinoma (HCC). Of 157 HCCs, 93 were CK7(-)CK19(-), 49 were CK7(+)-CK19(-), 1 was CK7(-)CK19(+), and 14 were CK7(+)- CK19(+). Semiquantitative analysis of expression levels(More)
A blind source deconvolution method without indeterminacy of permutation and scaling is proposed by using notable features of split spectrum and locational information on signal sources. A method for extracting human speech exclusively is also proposed by taking advantage of the rule, the property of FastICA separates sources in order of large(More)
This paper proposes Phoenix, a programming model for writing parallel and distributed applications that accommodate dynamically joining/leaving compute resources. In the proposed model, nodes involved in an application see a large and fixed <i>virtual node name space</i>. They communicate via messages, whose destinations are specified by virtual node names,(More)
We design and implement Virtual Private Grid (VPG), a shell that can easily and securely utilize a large number of machines distributed over multiple administrative domains. Today, many people have an access to a large number of machines across multiple subnets or geographically distributed places. These machines are managed by different administrators, and(More)
Expression of heat-shock protein 47 in intact and fibrotic liver and in hepatic constituent cells was investigated in mice. Immunohistochemical study of intact liver and Western blot analysis of the protein from isolated liver cells revealed that stellate cells and smooth muscle cells of interlobular vessels, but not hepatocytes, Kupffer cells, or(More)
Granulated metrial gland (GMG) cells are a major immune cell population in the murine pregnant uterus, and contribute to the maintenance of pregnancy by functioning as uterus-specific natural killer (NK) cells. In order to reveal their kinetics, activation, and functional roles in pregnancy, we conducted quantitative and immunohistochemical analyses in(More)
Activated hepatic stellate cells (HSCs) produce cyclooxygenase-2 (COX-2) protein to induce vascular endothelial growth factor (VEGF) production that participates in angiogenesis in injured liver. To reveal the unknown regulatory mechanism, we used hypoxic atmosphere mimicking injured-tissue microenvironment to induce VEGF expression in a rat hepatic(More)
Neural cell adhesion molecule (N-CAM) is distributed in most nerve cells and some non-neural tissues. The present immunohistochemical study has revealed, for the first time, the expression of N-CAM in perisinusoidal stellate cells of the human liver. Liver specimens were stained with monoclonal antibody against human Leu19 (N-CAM) by a(More)
 Liver failure following major hepatectomy is characterized pathologically by massive hepatic necrosis, which is thought to begin with injury of sinusoidal endothelial cells (SECs). To examine the early events of SECs leading to hepatic damage, we performed time-course analyses of the morphological and functional perturbation of SECs after endotoxin(More)
