The recent observation of a sharp selective bactericidal property possessed by gentian violet 1 raised the question as to which part of the gentian violet molecule was responsible for the sensitive affinity. It seemed wise to attack this problem by studying substances closely allied to gentian violet in chemical structure, 2 and the results obtained will be briefly reported in the present commu...

background: a highly efficient genetic transformation system is essential for a successful genetic manipulation of the african violet (saintpaulia ionantha wendl.).objectives: developing a particle bombardment-based genetic transformation system for the african violet.materials and methods: a local cultivar of the african violet from guilan province was used for transformation experiments. the ...

Several studies have validated the effectiveness of narrow-band imaging (NBI) in estimating invasion depth of early colorectal cancers. However, comparative diagnostic accuracy between NBI and chromoendoscopy remains unclear. Other than crystal violet, use of acetic acid as a new staining method to diagnose deep submucosal invasive (SM-d) carcinomas has not been extensively evaluated. We aimed ...

Bacterial colonization of polymeric medical aids causing so-called nosocomial infections is one of the main problems linked with the extensive use of polymeric devices in clinical applications. In this study, the properties of medical-grade polyvinyl chloride were modified by incorporating crystal violet into its bulk structure. Sodium montmorillonite was used as a carrier for the crystal viole...

Shades ranging from violet to black pigmentation in pepper (Capsicum annuum L.) are attributed to anthocyanin accumulation. High-performance liquid chromatography and mass spectrometry analysis of violet and black fruit tissue identified a single anthocyanin that was determined to be delphinidin-3-p-coumaroyl-rutinoside-5-glucoside. Leaf tissue of a black-pigmented foliage genotype contained th...

A series of aminotriarylmethane dyes were examined for binding to the nicotinic acetylcholine receptor (AChR) from Torpedo californica. Several compounds were found to bind to the noncompetitive antagonist site of the AChR as demonstrated by inhibition of [3H]phencyclidine binding; apparent KD values ranged from 50 nM to >100 microM. One dye with high affinity, crystal violet, revealed a greate...
