The patients with one or two of aforementioned parameters had significantly longer survival than those with three or four parameters (p = 0.017). In patients with largest mass (<= 5 cm), the risk grouping was found to be an independent prognostic factor (p = 0.022). However, differences in immunohistochemical staining were not related to patients’ survival. Conclusions: A risk grouping of MLC patients by using combinations of histologic
parameters can be a useful tool in evaluating the survival of patients with MLCs, and may indicate clonal relationship between multiple tumors.”
“Novel phase change materials based on paraffin and alumina-filled polyethylene (FPE) were prepared using a two-step process. In the first step, PE is synthesized using check details metallocene catalyst system. The synthesized PE is subsequently purified, whereas hydrated alumina-PE composites will be formed by the hydrolysis of aluminum organic cocatalyst and dispersion of hydrated alumina in the PE matrix. In the second step, paraffin-alumina-FPE composites were prepared by using the ex situ technique. Scanning electron microscopy, X-ray diffraction, Fourier-transform infrared spectroscopy, thermogravimetric analysis, selleck compound and differential scanning calorimetry were used to evaluate the structure and thermal properties of the composites. The results
show that the incorporation of a suitable amount of alumina into the composites changes their thermal stability. It is also possible to improve the thermophysical properties of the thermal energy storage materials by altering the paraffin ratio to the FPE. (c) 2010 Wiley Periodicals, Inc.

“Background: AS1842856 in vitro The purpose of this study was to describe
potential pitfalls in the diagnosis of metastatic adenocarcinoma in cerebrospinal fluid (CSF) and to suggest additional work in association with cytokeratin immunocytochemistry for the proper diagnosis, especially in the specimens with low cellularity. Methods: We collected 267 cytologic specimens of CSF from patients, who were diagnosed over a 9-month period. Each of the individual samples were divided into half the sample size and processed via both, ThinPrep (TP) with Papanicolau stain and cytocentrifugationbased preparation (cytospin, CP) with immunocytochemical stain for cytokeratin. Results: Amongst the 267 cases, 45 cases from 22 patients were diagnosed to be positive for metastasis adenocarcinoma in CSF. TP with Papanicolau stain showed satisfactory cytomorphology when compared with specimen of CP preparation and cytokeratin immunocytochemical staining. All the TP processed cases belonged to satisfactory/superior categories based on the assessment of technical artifact, which potentially helps in decreasing diagnositc errors.
