Malignant cells grown in culture excrete into their growth medium a folate catabolite that can be seen as a blue-fluorescent region on paper chromatograms of such media. This folate catabolite has now been identified by paper chromatography, thin-layer chromatography, and combined gas chromatography-mass spectrometry as 6- hydroxymethylpterin and not as pterin-6-carboxaldehyde as previously rep...
for art history issues. The task is complex however because of the highly heterogeneous character of a paint layer, which consists of a mixture of pigments and a binder on a support. All the components interact and infl uence the ageing process of the paint layer. The work described here is focused on understanding the discoloration over time of a particular pigment, Prussian blue, a synthetic ...
Cobalt-based blue ceramic pigments are widely used in ceramic industries due to characteristics such as temperature stability, chemical stability and high resistance to these coatings. In this research, the blue silicate - titanate cobalt ceramic pigment is synthesized by sol-gel method and the dispersed pigments were printed on the ceramic by silk screen printing method in the industrial produ...
Prussian Blue (ferric hexacyanoferrate(II)) was discovered accidentally by Johann Jacob Diesbach (1) and Johann Konrad Dippel (2) in Berlin in 1706 (3). As the first synthetic pigment, Prussian Blue received its name from the country in which its discovery occurred. It revolutionized the use of the color blue in artwork because it was less expensive and/or more stable than other blue pigments o...
Introduction: Several reports show a relationship between health equity, and health status and longevity of individuals. In this study, effects of food deprivation, inequality and social instability were investigated on the formation of lipofuscin pigment in Balb/C mice by histopathological and biochemical methods. Methods: Thirty-six male mice were divided into 6 groups, then different kind...
OBJECTIVES This study was carried out to detect vulnerable coronary plaques by color fluorescent angioscopy. BACKGROUND Collagen fibers (CFs) mainly provide mechanical support to coronary plaques. Oxidized low-density lipoprotein (Ox-LDL) induces macrophage proliferation, which in turn destroy CFs while accumulating lipids. As such, demonstration of the absence of CFs, deposition of lipids, a...
they form juxtaposed pointillistic colour centres which, to our eyes, create the stimulus of the colour green (the same principle is used in many neo-impressionist paintings). One further special feature of this structurally coloured system, and possibly the reason it evolved, is that only the blue colour component is significantly linearly polarised; linear polarisation is sometimes used for i...
