In a Linux cluster, as in any multi-processor system, the inter-processor communication rate is the major limiting factor to its general usefulness. This research is geared toward improving the communication performance by identifying where the inefficiencies lie and trying to understand their cause. The NetPIPE utility is being used to compare the latency(More)
The performance of the communication network can greatly affect the ability of scientific applications to make efficient use of the computational power available in high-performance computing systems. Many tools exist for analyzing network performance, but most concentrate on a single layer in the communication subsystem or on one type of network hardware.(More)
Iron deficiency anemia is an extra-stomach disease experienced in H. pylori carriers. Individuals with type A blood are more prone to suffering from H. pylori infection than other individuals. To clarify the molecular mechanisms underlying H. pylori-associated anemia, we collected erythrocytes from A, B, O, and AB blood donors and analyzed morphology, the(More)
MicroRNA has been recently recognized as playing a prominent role in tumorigenesis and metastasis. Here, we report that miR-338-3p was epigenetically silenced in gastric cancer, and its down-regulation was significantly correlated with gastric cancer clinicopathological features. Strikingly, restoring miR-338-3p expression in SGC-7901 gastric cancer cells(More)
Tumor initiation and growth depend on its microenvironment in which cancer-associated fibroblasts (CAFs) in tumor stroma play an important role. Prostaglandin E2 (PGE2) and interleukin (IL)-6 signal pathways are involved in the crosstalk between tumor and stromal cells. However, how PGE2-mediated signaling modulates this crosstalk remains unclear. Here, we(More)
MTA2 gene belongs to metastasis associated family, and is highly expressed in some solid tumors, including gastric cancer. Its biological function in gastric cancer is currently undefined. Metastasis-associated tumor gene family 2 (MTA2) and transcription factor specificity protein 1 (Sp1) expression were detected in 127 gastric cancer samples by(More)
Fibroblasts play a critical role in tumorigenesis, tumor progression and metastasis. However, their detailed molecular characteristics and clinical significance are still elusive. TAGLN is an actin-binding protein that plays an important role in tumorigenesis. We investigated the interaction between cancer cells and the tumor microenvironment to determine(More)
The purpose of the study was to investigate the expression of Aurora-A in human laryngeal squamous cell carcinoma (LSCC) and to explore the effects of Aurora-A silencing on invasion and chromosomal instability in laryngeal cancer HEp-2 cells. The expression of Aurora-A mRNA and protein were studied using reverse transcription-PCR and Western blot in LSCC(More)
