Crystal violet exhibited characteristics of an uncoupler of oxidative phosphorylation, i.e. it released respiratory control, hindered ATP synthesis, enhanced ATPase activity, and produced swelling of isolated rat liver mitochondria. Maximal stimulation of respiration, ATPase activity, and swelling was observed at a concentration of 40 microM. The inhibition of State 3 respiration by oligomycin ...

We study the statistical properties of melanoma cell colonies grown in vitro by analyzing the results of crystal violet assays at different concentrations of initial plated cells and for different growth times. The distribution of colony sizes is described well by a continuous time branching process. To characterize the shape fluctuations of the colonies, we compute the distribution of eccentri...

A new spectrophotometric method is proposed for the assay of ranitidine hydrochloride (RNH) in bulk drug and in its dosage forms using ceric ammonium sulphate (CAS) and two dyes, malachite (MAG) green and crystal violet (CV) as reagents. The method involves the addition of a known excess of ceric ammonium sulphate to ranitidine hydrochloride in acid medium, followed by the determination of unre...

The heterogeneous photo-Fenton degradation of crystal violet under visible light has been investigated usingcopper modified iron oxide. The photocatalyst has been prepared by coprecipitation method. The rate ofphotocatalyic degradation of dye was monitored spectrophotometrically. It has been observed thatphotocatalytic degradation follows pseudo first order kinetics. The effect of various param...

The ability of 71 strains of Salmonella enterica originating from produce, meat, or clinical sources to form biofilms was investigated. A crystal violet binding assay demonstrated no significant differences in biofilm formation by isolates from any source when tested in any of the following three media: Luria-Bertani broth supplemented with 2% glucose, tryptic soy broth (TSB), or 1/20th-strengt...

We report herein the G-quadruplex-selective property of a luminescent cyclometallated iridium(III) complex for the detection of adenosine-5'-triphosphate (ATP) in aqueous solution. The ATP-binding aptamer was employed as the ATP recognition unit, while the iridium(III) complex was used to monitor the formation of the G-quadruplex structure induced by ATP. The sensitivity and fold enhancement of...

INTRODUCTION Crystal violet was commonly used for the treatment of oral and vaginal candidiasis or for sterilization during operations up to the 1960s. Because crystal violet is potentially toxic to mucosal membranes, it has been replaced with other disinfectants, and crystal violet is rarely used. We report a case of chemical cystitis due to intravesical instillation of crystal violet dye. C...

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 ...

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...
