There is considerable debate In economics literatmre on ensure that the equilibrium flow of licensing higher-whether a decision by developing countries to strengthen qualitv goods meets these objectives. When the South their protectiot of intellectual property rights (IPRs) will strengthens its patent rights, copying by licensees is made increase or reduce(More)
Caveolin-1 (Cav-1) expression deficiency and autophagy in tumor stromal fibroblasts (hereafter fibroblasts) are involved in tumor proliferation and progression, particularly in breast and prostate cancer. The aim of this study was to detect the expression of fibroblastic Cav-1 and LC3B, markers of autophagy, in gastric cancer (GC) and to analyze their(More)

HER2 detection is important for breast cancer (BC) treatment and prognosis, but the detection methods currently used have some disadvantages. Quantum dots (QDs)-based probes provide a potentially important new method for HER2 detection in clinical practice. This potential is examined in this paper. A QDs HER2 probe kit and QDs image acquisition and analysis(More)
AIM To elucidate the role and alterations of syndecan-1 and E-cadherin expression in different cellular phenotypes of differentiated-type gastric cancers (DGCs). METHODS A total of 120 DGCs at an early stage, and their adjacent mucosa, were studied both by immunohistochemistry. Syndecan-1 and E-cadherin were assessed by immunohistochemical staining with(More)
To study the clinical significance of lymph node ratio (LNR) in gastric cancer (GC), this study analyzed 613 patients with GC who underwent surgical resection. Of 613 patients with GC, 138 patients who had >15 lymph nodes (LNs) resected and radical resection were enrolled into the final study. All major clinicopathological data were entered into a central(More)
AIM To examine the expression of nuclear factor kappaB (NF-kappaB) and its target genes in intestinal metaplasia (IM), dysplasia (DYS) and gastric carcinoma (GC) infected with Helicobacter pylori (H pylori) and to investigate the mechanism underlying H pylori cytotoxin associated gene A (cag A) infection leading to gastric adenocarcinoma. METHODS(More)
RATIONALE AND OBJECTIVES Both preoperative computed tomography (CT) staging and postoperative surgical Masaoka clinical staging are of great clinical importance for diagnosing thymomas. Our study aimed to investigate the relationships between these two staging systems. MATERIALS AND METHODS This was a retrospective review of 129 patients who had undergone(More)
AIMS Altered expression of epithelial or stromal caveolin-1 (Cav-1) is observed in various types of human cancers. However, the clinical significance of Cav-1 expression in gastric cancer (GC) remains largely unknown. The present study aims to explore the clinicopathological significance and prognostic value of both tumor cells and cancer associated(More)
Although the relationships between CXCR4 and EGFR expression and survival in non‑small cell lung cancer (NSCLC) have been studied independently, dual CXCR4/EGFR tumor status and its relationship with survival has not been previously investigated. In the present study, we examined the relationship between CXCR4 expression, EGFR expression and dual CXCR4/EGFR(More)
BACKGROUND/AIMS Transform growth factors beta (TGFbeta) plays different roles at different stages of tumor development. TGFbeta1 is one isoform of TGFbeta, with complex secretion mechanism and bidirectional functions. This study was to investigate TGFbeta1 expression and its clinical significance in different clinicopathological subgroups of gastric cancer(More)
