In the present work, the simultaneous determination of Brilliant green (BG) and Crystal violet (CV) dyes with overlapped absorption spectra in binary mixture solution, was carreid out using the partial least squares (PLS) and direct ortogonal signal correction-partial least squares (DOSC-PLS) methods. The results obtained indicate that by applying DOSC on the calibration and prediction data for...

An acetylene dye rotaxane with alpha-CD has been synthesized using the Heck-Cassar-Sonogashira-Hagihara-type reaction in aqueous solution. Free dye with tetracarboxylic acids is found to be highly sensitive to various metal ions, showing high Stern-Volmer constants, KSV. As CD encapsulation protects and stabilizes the threaded chromophore against an outside quencher, metal-insensitive biologica...

objectives: application of sealants is a safe and effective way to prevent occlusal caries in the posterior teeth. a successful sealant therapy depends on good isolation. decreased steps of adhesive application may enable proper isolation and use of self-adhering flowable composites for sealant therapy. this study sought to compare the marginal microleakage of fissure sealants and self-adhering...

The indocyanine green fluorescence imaging is a promising technique for sentinel node biopsy with advantages of dye-guided method, which is potentially safer, more convenient, and more cost-effective compared with the radioguided one. It could simplify the dye-guided method in both open and laparoscopic gastric cancer surgery, and possibly shortens the learning curve, which is one of the most c...

Cationic dyes of various natures have been investigated in order to select a dye that is stable under strongly alkaline conditions and applicable for the quantitative extraction-photometric determination higher carboxylic acids. The nature dye, solvent, length hydrocarbon radical acids pH aqueous phase extraction ionic associates with cationic pyronin G were experimentally studied. study substa...

Voltage-sensitive dye imaging of neurons is a key methodology for the understanding of how neuronal networks are organised and how the simultaneous activity of participating neurons leads to the emergence of the integral functionality of the network. Here we present the methodology of application of this technique to identified pattern generating neurons in the crab stomatogastric ganglion. We ...

This work reports the adsorption of crystal violet (CV) dye onto magnetic zeolite (MZ) nanoparticles, synthesized by direct fusion of fly ash (FA) and magnetite particles. The synthesised MZ showed high capacity for CV dye adsorption, removing 95% of the dye at an equilibrium adsorption time of 10 min and 25 ̊C. The effects of adsorbent dosage, dye concentration, and pH, on adsorption were evalu...

[Purpose] This study aimed to examine the effects of low-dye taping on paretic side plantar pressure in patients with plantar fasciitis. [Subjects] The 30 patients in this study were randomly allocated to a low-dye taping group (n = 15) or a conservative treatment group (n =15). [Methods] Both groups received treatment thrice a week for six weeks. BioRescue was used to measure the weight distri...
