Technological investigation of luster decorated ancient majolicas
No full textIn this work some luster decorated ancient ceramics have been analyzed in order to acquire knowledge about technological procedures in luster production during the Renaissance period in Italy. Luster is a thin decorative metallic film present on the surfaces of some previously glazed ancient majolicas. It was obtained by applying on the majolica surface a mixture containing silver and copper compounds. Subsequently the object was fired in a reducing atmosphere. It was found that the luster color, red-like or gold-like, depends not only on the chemical composition, determined by Inductively Coupled Plasma Emission Spectroscopy (ICP-OES), but on the dimensions of silver and copper metallic nanoparticles forming the luster too. Nanocrystals' dimensions and structural characteristics were determined by Transmission Electron Microscopy (TEM). As obtaining a satisfactory luster depends on the composition of the underlying glaze too, the chemical composition of the glazes have been determined and the analytical data were submitted to statistical multivariate analysis
Measurement of hair luster by diffuse reflectance spectrophotometry
No full textWe studied the application of the diffuse reflectance spectrophotometry technique in order to obtain consistent hair-luster measurements. The influence on data quality of such experimental conditions as sample color, texture, geometry, and position, and of such instrumental operating conditions as viewing angle, viewing aperture, and inclusion or exclusion of the specular component, were established. The color-difference parameter (DE) appears as the best parameter to measure hair luster in CIELAB and FMCII systems of equations. Hair tresses submitted to several treatments, including shampooing and conditioning, were used to choose the best reference (zero-luster value) and hair-luster saturation (maximum-luster value). A luster scale was assembled from DE values, pointing out that diffuse reflectance spectrophotometry data allows measuring and quantifying hair luster.51528930

Pearl luster and shelf-life enhancement through pearl treatment
No full textTo investigate the pearl luster and shelf life enhancement a study was conducted at the Pearl laboratory, Bangladesh Fisheries Research Institute, Mymensingh with rice pearls and image pearls from July 2017-June 2018. Rice pearls and image pearls were kept in bottles, each filled with different concentrations (10%, 15%, 20%, 25%, 30%, 35%, 40%) of H2O2,CH3OH and C2H5OH solutions and kept in treatment units under (1,700-15,300 lumens) and at a temperature of 33-400C for 4 months. Shelf life of the treated pearls were measured by examining the longevity of the luster for a period of eight months. Treatments were used for enhancement of pearl quality. During the experiment highest luster increase (49%) was observed in treatment with 10% C2H5OH followed by treatment with 10% CH3OH (47%), 15% C2H5OH (43%), 15% CH3OH (39%). Decaying and decrease in pearl luster was found in treatments with 30, 35 and 40% H2O2 (-23%, -29% and -38%); 35 and 40% CH3OH treatment (-8% and -13%); 40% C2H5OH treatment (-7% and -15%, respectively. Current study revealed that pearl treatment with 10% C2H5OH for four months showed better peal luster and shelf life
Luster pottery from the thirteenth century to the sixteenth century: A nanostructured thin metallic film
No full textLuster is a decorative metallic film that was applied an the surface of medieval glazed pottery. It can be obtained via the low-temperature (similar to 650 degreesC), controlled reduction of copper and silver compounds. In this paper, we show that luster is a thin layered film (200-500 nm thick) that contains metallic spherical nanocrystals dispersed in a silicon-rich matrix and has a metal-free outermost glassy layer that is 10-20 nm thick. Silver nanocrystals seem to be separated from those of copper, forming aggregates 5-100 pm in diameter. This composite structure exhibits optical properties that are dependent on both the particle size and the matrix. Luster is indeed the first reproducible nanostructured thin metallic film that was made by humans
Pentamidine blocks the pathophysiologic effects of endotoxemia through inhibition of cytokine release
No full textPentamidine isethionate, an antiprotozoal agent with therapeutic value against Pneumocystis carinii pneumonia, has been used for over 30 years without a precise understanding of its mechanism of pharmacologic action. We have previously reported that pentamidine has the capacity to inhibit the release of cytokines from macrophages through a post-translational processing event. The present studies were undertaken to assess the ability of pentamidine to modulate the detrimental effects of murine endotoxemia, a disease with a pathophysiology clearly linked to host-produced cytokines. Under conditions where normal B6C3F1 mice succumbed to the lethal effects of endotoxin, mice pretreated with pentamidine were significantly protected from both mortality and loss of thermoregulatory control. The EC50 for protection from mortality by pentamidine was approximately 11.4 mg/kg. These observations correlated with decreased serum levels of tumor necrosis factor (TNF) and interleukin 6. Inhibition of cytokines was not manifested as part of a generalized inhibition of protein synthesis as demonstrated by the lack of significant modulation of serum albumin in pentamidine-treated animals. In addition to decreased serum concentrations of cytokines, lungs isolated from mice treated with both pentamidine and endotoxin exhibited a decreased release of TNF compared to lungs isolated from mice treated with vehicle and endotoxin. The lower levels of TNF released from lung tissue in pentamidine- treated mice correlated with a lesser degree of alveolar deterioration than was observed in vehicle-treated mice. These data indicate that following endotoxin administration, pentamidine has a protective and antiinflammatory role both systemically and in the lung and suggest that inhibition of inflammatory cytokines may be one mechanism operable in the therapeutic activity of the drug against P carinii pneumonia
