Cyanine–aryl acetylene conjugates (pink) accumulate in the mitochondria of cancer cells, where elevated pH and reactive oxygen species (white) levels allow formation thiyl radicals (yellow glowing pin first arrow) from thiols (dark yellow pin). The activation enables radical thiol-yne coupling biomolecules to dye–alkyne conjugate (second arrow). This represents a powerful tool for selective tar...
The adsorption behaviour of Methyl violet and Auramine yellow from aqueous solution onto Stishovite clay was investigated as a function of parameters such as initial dye concentration, contact time, p and temperature. The Langmuir and Freundlich adsorption models were applied to describe the equilibrium isotherms. Adsorption followed pseudo-second order model. The experimental data fitted well ...
I found some mistakes on Table 2 (page 1643) in my published paper in Materials [1]. A correct table is provided here. Table 2. The relationships between molecular structures of yellow anthraquinone dyes and their solubilities and dichroic ratios. Dye Solubility (wt %) 1) Dichroic ratio r. t. Low temp.
Herein we report, the robustness of UV/H2O2/Fe2+ system for efficient decolorization of azo-dye Acid Yellow (AY17) solution. It has been found that 88% AY17 decolorized by UV/H2O2/Fe2+ system in 25 minutes under the following optimized conditions; [dye] = 0.14 mM, [H2O2] =1.0 mM, [Fe<s...
BACKGROUND Enzymatic elimination of synthetic dyes, one of the most environmentally hazardous chemicals, has gained a great interest during the two last decades. The present study was performed to evaluate the decolorization and detoxification potential of the purified laccase of Paraconiothyrium variabile in both non-assisted and hydroxybenzotriazole-aided form against six azo dyes. RESULTS ...
Chromonic phases are a family of lyotropic liquid crystals (LC) formed by ionic aromatic mesogens such as disodium cromoglycate (cromolyn), sunset yellow and others. It is well known that chromonic phases are oriented in the presence of external magnetic fields, leading to the observation of anisotropic NMR observables such as quadrupolar splittings or residual dipolar couplings. Despite the fa...
A method is described for counterstaining tissue for use with the glyoxylic acid reaction for visual detection of biogenic amines. Counterstaining is achieved by addition of the fluorescent dye malachite green to the sucrose-phosphate-glyoxylic acid (SPG) solution used for processing of cryostat sections of unfixed tissues. When bound to tissues, the dye provides red-orange fluorescence of back...
در این مطالعه نانوالیاف pva/dye در غلظت های مختلف با موفقیت آماده و به عنوان لایه حساس کننده در سلول های خورشیدی استفاده شد. نانوالیاف به دست آمده با روش تحلیلی مانندftir ، طیف سنجی uv-visو sem مورد بررسی قرار گرفت. تجزیه و تحلیل ساختاری وجود رنگزا در نانوالیاف pva/dye الکتروریسی شده را تایید کرد. باتوجه به نتایج جذب uv-vis راندمان تبدیل بالاتر برای نانولایه ی pva/dye که در غلظت 15? از محلول پل...
PURPOSE To investigate the relationship between gap-junction mediated intercellular communication and the proliferative activity of retinal pigment epithelial cells in the retinal tear base. METHODS Retinal tears were created experimentally in white rabbits, and the changes of intercellular communication via gap junctions between retinal pigment epithelial cells in the retinal tear base were in...
