The current study enumerates the use of supported liquid membrane (SLM) technology to remove and recover crystal violet dye from wastewaters. management textile industry waste effluents is one main concerns environmental health experts due having excessive concentrations dyes resistance biodegradation. Liquid membranes offer an affordable green method for selective removal aqueous solutions. To...
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...
conclusions these results indicate that a. kellalensis extracts exert potent anti-rotaviral activity only after viral adsorption. the two extracts from a. kellalensis showed a good selectivity index. also these results suggest that extracts prepared from the flowers of a. kellalensis may be potential anti-rotaviral agents in vivo and be useful in veterinary medicine. background achillea kellale...
The feasibility of liquid-phase evanescent-wave cavity ring-down spectroscopy (EW-CRDS) for surface-binding studies under flow-injection analysis (FIA) conditions is demonstrated. The EW-CRDS setup consists of an anti-reflection coated Dove prism inside a linear cavity (with standard or super-polishing of the total internal reflective (TIR) surface). A teflon spacer with an elliptical hole clam...
Many years ago Hertwig (1) and Dalcq (2) showed that trypaflavine has the property of inactivating the frog sperm nucleus without affecting the extranuclear parts of the cell. Following an appropriate treatment with the dye, the sperm cells still retain their capacity to activate eggs, but contribute no chromosomes to the resulting embryos, which then develop as haploids with the maternal chrom...
Borzani and Vairo (1959) reported that grampositive and gram-negative microorganisms are fundamentally different with respect to crystal violet adsorption. They claimed that the binding of crystal violet by gram-positive cells followed the Freundlich and the Langmuir adsorption laws; whereas the binding of crystal violet by gram-negative cells did not follow any known adsorption law. The presen...
1. Bacterial spores are highly resistant to the bactericidal action of the triphenylmethane dyes. Many Bacillus anthracis and Bacillus subtilis spores resist a saturated aqueous solution of gentian violet for 24 hours at 37 degrees C. They also resist exposure to the same dye solution for 10 minutes at 80 degrees C. 2. The selective bactericidal action of these dyes applies only to the vegetati...
Bimetallic Au –Pt catalysts supporting TiO2 were synthesised using two methods; sol immobilization and impregnation methods. The prepared catalyst underwent a thermal treatment process at 400◦ C, while the reduction reaction under same condition was done obtained identified with transmission electron microscopy (TEM) energy-dispersive spectroscopy (EDS). It has been found that have dimension ar...
