A 62-year-old woman was diagnosed as an ovarian cancer on abdominal CT. However, it was diagnosed as a cystadenofibroma on magnetic resonance T2-weighted AZD8186 images that showed the solid components of the tumor with very low intensity. Although ovarian cystadenofibroma is a relatively rare benign tumor, its ultrasonographic feature of cystic lesions with solid components resembles that of malignant ovarian tumor.

MRI was considered to be useful modality for ovarian cystadenofibroma to be effectively diagnosed preoperatively.”
“The

dependence of the magnetization profile of Co/Pd multilayer films with very thin individual layers, Co (0.4 nm)/Pd (0.6 nm), on the energy of ion milling is investigated using scanning electron microscopy with polarization analysis (SEMPA). The effect of Ar ion milling on the Co/Pd magnetization angle distribution is compared for ion milling at 50 eV, 1 keV, and 2 keV. We find that 1 and 2 keV Ar ion milling causes a measurable change in the out-of-plane magnetization angle distribution as material is removed, but ion milling with 50 eV Ar ions does not significantly alter the magnetization. This enables quantitative imaging of all three vector components of the surface magnetization of the Co/Pd multilayer films with 20 nm lateral Quisinostat spatial resolution using SEMPA.

“A series of

sulfonated poly(ether sulfone) (SPIES)/silica composite membranes were prepared by sol-gel method using tetraethylorthosilicate (TEOS) hydrolysis. Physico-chemical properties of the composite membranes were characterized by thermogravimetric analysis (TGA), X-ray diffraction (XRD), scanning electron microscope-energy CH5424802 nmr dispersive X-ray (SEM-EDX), and water uptake. Compared to a pure SPIES membrane, SiO(2) doping in the membranes led to a higher thermal stability and water uptake. SEM-EDX indicated that SiO(2) particles were uniformly embedded throughout the SPIES matrix. Proper silica loadings (below 5 wt %) in the composite membranes helped to inhibit methanol permeation. The permeability

coefficient of the composite membrane with 5 wt % SiO(2) was 1.06 x 10(-7) cm(2)/s, which was lower than that of the SPIES and just one tenth of that of Nafion (R) 112. Although proton conductivity of the composite membranes decreased with increasing silica content, the selectivity (the ratio of proton conductivity and methanol permeability) of the composite membrane with 5 wt % silica loading was higher than that of the SPIES and Nafion (R) 112 membrane. This excellent selectivity of SPIES/SiO(2) composite membranes could indicate a potential feasibility as a promising electrolyte for direct methanol fuel cell. (C) 2010 Wiley Periodicals, Inc.
