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...

conclusions vo can be presented as a safe, well-tolerated, and effective herbal preparation in patients with chronic insomnia. results improvements in sleep and isi scores were significantly greater in patients after a month receiving vo drop in comparison with before starting treatment (p < 0.05). a few patients reported some complications about vo consumption, most of which were mild and no s...

There have been a considerable number of studies on alkali molecular diffuse bands concerning their excimertype nature.’ Such diffuse bands might be developed as possible sources of tunable, high-power lasers.2 Fluorescence of a Naa violet diffuse band could be observed either by one-photon excitation of X’c,’ w C’II, or two-photon excitation of an X’c,’ -+ A’C: -+ high-lying g state in Na,, or...

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 ...

Various reactive oxygen and nitrogen species are accompanied by electrons, ultra-violet (UV) radiation, ions, photons, electric fields in non-thermal atmospheric pressure plasma. Plasma technology is already used diverse fields, such as biomedicine, dentistry, agriculture, ozone generation, chemical synthesis, surface treatment, coating. Non-thermal plasma also considered a promising environmen...

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...
