7Edberg SC, Bottonbley CJ and Gam K. Use of sodium polyanethol sulfonate to selectively inhibit aminoglycoside and polymyxin antibiotics in a rapid blood level antibiotic assay. There are numerous empirical methods for staining elastic fibres.' Most require relatively lengthy procedures which involve overnight incubation, and are therefore not adapted to simultaneous evaluation with the corresp...

Tungsten trioxide nanoparticles with monoclinic structure and average particle size about 80 nm were prepared by the spray pyrolysis method. WO3 nanorods with hexagonal structure and average dimension about 15 × 100 nm were synthesized in gram quantities by modified hydrothermal method at lower temperature and shorter reaction time in comparison to the previous research. Photo de...

Hydrothermal synthesis of nickel-chitosan hybrid  has  been accomplished using Ni(CH3COO)2,4H2O, chitosan and water as starting material, template and solvent respectively, followed by calcination at 800 and 900˚C to provide nanoporous NiO800  and NiO900. The solid products were characterized by X-ray diffraction (XRD), nitrogen adsorption-desorption, scanning electron microscopy (SEM) and Four...

A kinetic-spectrophotometric procedure is reported for determination of trace amounts of Ag(I). This method is based on catalytic effect of silver ion on the oxidation of congo red by potassium peroxodisulphate at pH=3.4 and 30 oC in the presence of 1,10-phenanthroline as an activator. The reaction was followed spectrophotometrically by measuring the rate of change in absorbance ...

Background: A rippled type of pigmentation is observed on the arms, forearms, and bony prominences, more commonly in women with a history of chronic rubbing. The terminology (commonly referred to as frictional melanosis) and its relation with cutaneous amyloidosis has been debated. Materials and Methods: Twenty one patients with pigmented skin lesions with manifestations suggestive of frictiona...

The phosphomolybdic acid (PMA) has been used as an adsorbent for the removal of dyes (Methylene blue and Congo red dye) from synthetic aqueous solution. Different factors of the adsorbent, like, contact time, pH of the sorption medium, concentration of the dye solution, were investigated by the batch sorption experiment. The adsorption equilibrium data was best fitted by the Langmuir isotherm m...

Tungsten trioxide nanoparticles with two different sizes (average particle sizes about 50 and 80 nm) were prepared by the spray pyrolysis method. Photo degradation of Congo Red (azo dye) showed that photo catalytic property of the as-prepared WO3 nanoparticles with average size about 80 nm is higher than the sample with average size about 50 nm. Photo degradation of Rhodamine B (...

the study was undertaken to answer the question that how many patients with pigmentation of back and arms actually have amyloid deposits in pathology. 44 patients presenting with diffuse pigmentation of back and arms (dpoba) were selected. skin biopsies were performed in all cases from the affected sites. on all formalin fixed and paraffin embedded specimens, the following histochemical stains ...

Cadmium oxide rhombus-shaped nanostructure was synthesized using hydrothermal process followed by heating treatment. Clearly, X-ray diffraction pattern demonstrated the formation of CdO crystalline phase. Scanning electron microscopy (SEM) showed that the obtained rhombus-like structure is composed of nanoparticles with the average size of 29 nm. In addition, we evaluated adsorption of org...

Only 6 cases with an association of disseminated superficial porokeratosis with dermal amyloid deposits are reported in the literature. We present the case of a 76-year-old woman who presented with a disseminated superficial porokeratosis. Histological examination revealed amyloid deposits in the upper dermis, which were typed with routine HE stains, Congo red stains and anticytokeratin antibod...
