Conclusions: Immunocytochemical stain for cytokeratin along with TP processed specimen helps in decreasing potential diagnostic errors in the cytological diagnosis of metastatic carcinoma in CSF specimen.”
“The effect of epoxy-based cross-linking additives with different functionalities on the photolithographic properties, adhesion to substrates, and cross-link density of a tetramethyl ammonium hydroxide-developable polynorbornene-based dielectric was investigated. Three different multifunctional

epoxy additives were investigated: difunctional, trifunctional, and tetrafunctional compounds. It was found that incorporation of a small quantity (1 wt % of solution) of an ultraviolet-absorbing tetrafunctional cross-linker, tetraphenylol PCI-32765 order ethane tetraglycidyl ether, activated selleck kinase inhibitor the photo-catalyst

and improved the sensitivity of a previously photosensitive polynorbornene-based formulation by a factor of 3.7. The impact of the epoxy cross-linkers on the physical and optical properties of the polymer formulations was evaluated. The contrast was improved from 7.37, for the control formulation, to 24.2. The polymer-to-substrate adhesion was also improved by addition of the tetrafunctional epoxy cross-linker, which facilitates the development of high-aspect-ratio structures. Hollow-core pillar structures in 40-mu m-thick films with a depth-to-width aspect ratio of 13 : 1 were produced. The cross-link density was Selleckchem MLN4924 studied by using swelling measurements of cured films to evaluate the average molecular weight between cross-links. (c) 2010 Wiley Periodicals, Inc.

“Cavernous hemangioma of the uterus is an uncommon mesenchymal tumor. Most cases have been reported in young, pregnant women and the condition is very rare in a postmenopausal patient. An 81-year-old woman presented with a huge pelvic mass. Abdominal computed tomography and magnetic resonance imaging results suggested a leiomyoma with degenerative change and hemorrhage. Microscopically, large, thick-walled

and variable-sized vascular channels were evident in the majority part of myometrium; the lining cells were immunohistochemically reactive for CD31. Vascular tumors of the female genital tract should be cautiously excised due to the profuse intra-operative bleeding. The pathological examination of a hysterectomy specimen is the only method to confirm the diagnosis of this tumor.”
“In this study, ethylene-propylene-diene monomer (EPDM)/fibrillar silicate (FS) nanocomposites were successfully prepared by mechanically blending EPDM with FS, which was modified by silane coupling agent KH570 containing methacryloxy group. The effects of silane content and modified FS on the dispersion of FS and mechanical properties of the composites were investigated. The impact of water in FS on mechanical properties of the composites was also evaluated.
