Moreover, the swelling behavior of the CMCh/PVA hydrogels was studied in different buffered solutions and in different salt solutions at various concentrations. CMCh/PVA hydrogels swell much more than CMCh especially at alkaline pH. Both metal and dye uptake were studied for CMCh/PVA hydrogels. The hydrogels adsorb much more dyestuff and metal ions like Cu2+, Cd2+, and Co2+ than CMCh itself. Much dyestuff and metal ions are adsorbed by the hydrogels as PVA content increases in the hydrogel. selleck chemical (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci 123: 3459-3469, 2012″
“Background
Meningioangiomatosis is a meningovascular disorder that only rarefy occurs in association
with a meningioma. Occasionally, as in this case, imaging g studies do not readily identify this disorder as a benjn process. In addition, this disorder may infiltrate the underlying cerebral cortex, simulating, intraoperatively, it malignant infiltrative process. To allow better recognition of this disorder, we report it
case with emphasis on the unique cytologic features of the 2 components (meningioangiomatosis and meningioma) and potential pitfalls in diagnosis.
Case
A 3-year-old girl was examined in the neurosurgery service for history of refractory seizure. Neuroimaging showed an ill-defined signal abnormality in the left frontal lobe suggestive of it high-grade BAY 73-4506 cell line tumor. Tumor resection was performed, and intraoperative smear preparation showed meningioangiomatosis associated with meningioma.
Conclusion
Familiarity with cytologic preparations of this rare variant is very important in providing accurate introperative consultation. To our knowledge, this is the first description of the cytologic features oil smear preparation of meningioangiomatosis occurring in association with meningioma. (Acta Cytol 2009;53:93-97)”

distribution in a spherically symmetrical metal-insulator-semiconductor structure with a tunnel-thin insulating layer has been analyzed using the proposed analytic model and compared with that in a regular planar structure. In many electrostatic respects, the spherical system was shown to behave like a planar one with higher than specified semiconductor doping level. Special attention is paid to the reverse bias polarity. With a decrease of BKM120 the insulator-semiconductor interface radius, for a fixed terminal bias, the insulator voltage becomes higher and the band bending smaller. The geometry effects are revealed for the radii below 100-200 nm, i.e., by far not in the extreme quantum limit. The elaborated model is useful for treatment of non-planar metal-insulator-semiconductor structures in the cases when the consideration of an exact topology is problematic or too speculative.
