BACKGROUND The aim of this study was to identify the unique molecular characteristics of biliary tract cancer (BTC) for the development of novel molecular-targeted therapies. MATERIALS AND METHODS We performed mutational analysis of KRAS, BRAF, PIK3CA, and FBXW7 and immunohistochemical analysis of EGFR and TP53 in 63 Japanese patients with BTC and retrospectively evaluated the association bet...
Dispersive effects induced by weak hydrostatic imbalance in the presence of topography and stratification are incorporated into a new model of barotropic (vertically integrated) mesoscale ocean dynamics. This barotropic model is obtained by first expanding the solutions of three dimensional Euler-Boussinesq equations in a regular perturbation expansion in terms of the several small dimensionles...
Cu3(BTC)2 is an efficient and reusable heterogeneous catalyst for the dehydrogenative coupling of silanes with alcohols. Activity data and CO adsorption suggest that Cu(II) and in situ generated Cu(I) are the active species. Other MOFs such as Fe(BTC), MIL-101(Cr) and UiO-66(Zr) are unable to promote this cross-coupling.
Rietveld analyses of neutron powder diffraction data of D2 in Cu3(BTC)2, where BTC = 1,3,5-benzenetricarboxylate, reveals the location and progressive filling of six distinct D2 sites within the nanopore structure. Location of the primary site at the coordinatively unsaturated Cu atoms provides direct structural evidence of the potential importance of such metal sites to hydrogen storage. Compe...
Biliary tract cancer (BTC) is the second most common primary hepatobiliary cancer after hepatocellular cancer. At the time of diagnosis, most BTC are at an advanced stage and are unresectable. There is presently no effective curative treatment of the advanced disease nor is there any effective clinical therapy that will prevent the development of BTC. All of these factors render gallbladder can...
Extensive stromal interaction is one reason for the dismal outcome of biliary tract cancer (BTC) patients. Epithelial to mesenchymal transition (EMT) is involved in tumor invasion and metastasis and is partly regulated by microRNAs (miRs). This study explores the expression of anti-EMT miR200 family (miR141, -200a/b/c, -429) and miR205 as well as the EMT-related proteins E-cadherin and vimentin...
BACKGROUND The patterns of radiotherapy (RT) practice for biliary tract cancer (BTC) in Japan are not clearly established. METHODS A questionnaire-based national survey of RT used for BTC treatment between 2000 and 2011 was conducted by the Japanese Radiation Oncology Study Group. Detailed information was collected for 555 patients from 31 radiation oncology institutions. RESULTS The median...
Copper trimesate (Cu-BTC) MOF has been pointed out as a promising adsorbent for separating carbon dioxide from methane. However, MOF’s need to be shaped prior to their use in packed bed adsorbers in order to reduce pressure drop; on the other hand, the production of mechanically resistant shaped bodies reduces their adsorption performance. In this work, Cu-BTC tablets provided by BASF are evalu...
BACKGROUND The optimal treatment strategy for biliary tract cancer (BTC) after curative-intent resection remains controversial. The purpose of this study was to evaluate the efficacy of fluoropyrimidine-based adjuvant chemotherapy for BTC patients undergoing microscopically margin-negative (R0) resection. METHODS We retrospectively analyzed the clinical data of BTC patients who underwent cura...
Mode-1 internal tides were observed the western North Atlantic using an ocean acoustic tomography array deployed in 1991–1992 centered on 251N, 661W. The pentagonal array, 700-km across, acted as an antenna for mode-1 internal-tides. Coherent internal-tide waves with O(1m) displacements were observed traveling in several directions. Although the internal tides of the region were relatively quie...
