High mobility group box 1 (HMGB1) was originally defined as a nuclear protein. However, later studies showed that HMGB1 was released from damaged cells into the extracellular milieu and functioned as a danger signaling molecule. HMGB1 has also been shown to exert proliferative and chemoattractant effects on many cell types. In this study, we investigated the in vitro effect of human recombinant...

Dental cementum is a specialized calcified structure covering the root of a tooth. This study aims to investigate cementum using various stains which can be exceedingly useful in investigation, observation and diagnosis. 4µm sections of 25 extracted normal teeth, 25 cases of various cemental pathologies and 25 ground sections were stained using cresyl violet, H/E, toluidine blue and periodic ac...

In this research, a response surface methodology (RSM) was used to investigate the effects of independent parameters (pH, contact time, temperature, adsorbent dosage, and initial concentration of pollutant), their simultaneous interactions, and quadratic effects on crystal violet adsorption onto two starch based materials in the form of batch experiments. The characterizing results indicated th...

Copper (I) oxide microparticles with the morphology of cubic and hollow sphere were synthesized with the assistance of surfactant as the shape controller. Both particles were then subjected to study the catalytic activity and observed the results of shape effects of catalysts on rate of catalytic reaction. The decolorizing reaction of crystal violet and sodium hydroxide was chosen and measured ...

Two-component relativistic time-dependent density functional theory calculations with spin-orbit coupling predict yellow and orange-red absorption for BiPh5 and BiMe5, respectively, providing an excellent explanation for their respective violet and blue-violet colors. According to the calculations, the visible absorption is clearly attributable to a single transition from a ligand-based HOMO to...

Adsorption techniques are widely used to remove the pollutants from waters, especially those that are not easily biodegradable. The removal of crystal violet dye (CVD) from water was studied by using Amberlyst 15, a cation-exchange resin (CER), along with Ferrous (Fe 2+ ) and H2O2 . In this study the main factors that can influence the degradation of crystal violet dye are molar ratio of [(H2O2...

Many fish, amphibians, reptiles, birds, and some mammals use UV vision for such basic activities as foraging, mate selection, and communication. UV vision is mediated by UV pigments in the short wavelength-sensitive type 1 (SWS1) group that absorb light maximally (lambda max) at approximately 360 nm. Reconstructed SWS1 pigments of most vertebrate ancestors have lambda max values of approximatel...

Although they combine the best of covalent and non-covalent bonds, dynamic covalent bonds are usually not used together. Building on pioneering examples for functional systems with two orthogonal dynamic covalent bonds, we herein elaborate on multicomponent surface architectures that operate with three different types of dynamic covalent bonds. Disulfide exchange under basic conditions is used ...

Results with two ultramicro methods for plasma uric acid analysis with uricase are described: a crystal violet (gentian violet) method, modified from an automated procedure by Gochman and Schmitz [C/in. Chem. 17, 1154 (1971)] and adapted to manual analysis, and a polarographic oxygen-sensing system (Beckman Instruments,Inc.).The coefficientof variation (CV) for the crystal violet method varied ...
