We examined the effects of dimethyl sulfoxide (DMSO), hyaluronidase and saponin on drug absorption through the bladder mucosa. Female Wistar rats underwent intravesical instillation of each agent prior to the administration of lanthanum solution or anticancer drug; 4'-O-tetrahydropyranyldoxorubicin (THP). The absorption of lanthanum was recognized as dense grain in bladder tissue under electron...

The recent Spitzer detections of the 9.7μm Si–O silicate emission in type 1 AGNs provide support for the AGN unification scheme. The properties of the silicate dust are of key importance to understanding the physical, chemical and evolutionary properties of the obscuring dusty torus around AGNs. Compared to that of the Galactic interstellar medium (ISM), the 10μm silicate emission profile of ty...

Among the techniques which have been reported to stain the surface coat of cells, for electron microscopy, is lanthanum staining en bloc. Similarly, the presence of the cationic dye, Alcian blue 8GX, in a primary glutaraldehyde fixative has been reported to improve the preservation of the surface coat of cells of many types; however, the preserved coat is not very electron opaque unless thin se...

Cerium doped lutetium silicate powders were prepared by solegel process with different cerium concentrations (0, 0.01 and 0.03 mol%). The synthesized lutetium silicate powders were investigated by X-ray diffraction (XRD), TG-DTA, SEM, and Photoluminescence excitation and emissions. The crystallization of lutetium silicate is observed at 1.073 C in S2 (and S3: 1.058 C) sample. The formation of l...

The exploitation of massive rare-earth element (REE) deposits is frequently contested because the pollution generated by heavy mining operations and REE extractive metallurgy operations. In an effort to minimise environmental footprint production meet increasing demand for these elements, mine wastes tailings are attracting attention as alternative primary sources. However, residues contain sma...

The structure of the 5 p 5 p R26:6 reconstruction of LaAlO3 (001) has been determined using transmission electron diffraction combined with direct methods. It has a lanthanum oxide termination with one lanthanum vacancy per surface unit cell. Density functional calculations indicate that charge compensation occurs by a fractional number of highly delocalized holes, and that the surface contains...

Experiments are performed at the Enormous Toroidal Plasma Device at UCLA to study the neutral boundary layer (NBL) between a magnetized plasma and a neutral gas along the direction of a confining magnetic field. This is the first experiment to measure plasma termination within a neutral gas without the presence of a wall or obstacle. A magnetized, current-free helium plasma created by a lanthan...

concrete is one of the most utilized construction materials in the world. nowadays, nano silicate usage due to its special property attracted considerable attention. on this basis, studying its environmental functions is an essential issue. accordingly, the behavior of normal concrete and the one with nano silicate were compared via taking advantage of life cycle assessment (lca) method in this...

Controlled conversion of right-handed B-DNA to left-handed Z-DNA is one of the greatest conformational transitions in biology. Recently, the B-Z transition has been explored from nanotechnological points of view and used as the driving machinery of many nanomechanical devices. Using a combination of CD spectroscopy, fluorescence spectroscopy, and PAGE, we demonstrate that low concentration of l...
