The application of Leuco Crystal Violet (LCV) for the enhancement of footwear and fingerprint impression evidence was first utilized in the FBI Laboratory in late 1993, after learning from Mr. John F. Fischer (1) of the formulation of this reagent. Mr. Fischer subsequently made a presentation on this topic at the International Symposium on Footwear and Tire Tread Impression Evidence at the FBI ...

Effluent of various industries contain number of inhibitory substances which are continuously added in sea via river and results in water pollution. There is need to degrade the organic content to abate water pollution. In the present study, actinomycetes were isolated on glycerol aspargine agar from marine sample of Calangut beach, Goa. The isolates were tested for their potential to tolerate ...

Objective
 The aim of this study was to compare four commonly
 used cytotoxicity assays (XTT, neutral red uptake, crys-
 tal violet assay, and propidium iodide staining) which
 analyzed the antiproliferative effects vitamin K2.
 Material Method
 Saos-2 cells, an osteosarcoma cell line, were
 exposed K2 at different concentrations (10
 μM, 20 30 40 50 100 ...

The effect of oxidative stress exerted by 0.03% crystal violet, 0.3% bile salt, 4.0% NaCl and 8% ethanol on the survival and production of virulence factors among Acinetobacter haemolyticus isolates obtained from wastewater and river water samples was investigated. Though generally there was insignificant lethal effect against all the isolates, crystal violet exerted the highest lethal effect f...

Introduction The reduced susceptibility of biofilms to disinfectants presents a challenge the successful reprocessing medical equipment. This study examined effect residual biomass remaining after previous disinfection with peracetic acid (PAA) on tolerance subsequent mature Pseudomonas aeruginosa PAA. enzymatic degradation specific components extracellular polymeric substance (EPS) P. biofilm ...

Ninety-nine selected compounds and eleven antibiotic-producing organisms were tested for antiphage activity and host toxicity. A paper disc-agar diffusion method was used for primary screening and quantitative methods were employed for confirmatory investigation. Most of the agents tested, although previously reported as inhibitory to one or more other virus-host systems, did not selectively pr...

Purpose : To investigate the modulatory effect of natural phytochemical, carvacrol, on Topotecan (TOPO) cytotoxicity and cellular uptake in different cancer cell lines. Methods The carvacrol/TOPO combination therapy was determined vitro using crystal violet assay. Coomassie blue DAPI fluorescent stains were used for morphology molecular death assessments, respectively. Additionally, TOPO after ...

Plasmid pGNB1 was isolated from bacteria residing in the activated sludge compartment of a wastewater treatment plant by using a transformation-based approach. This 60-kb plasmid confers resistance to the triphenylmethane dye crystal violet and enables its host bacterium to decolorize crystal violet. Partial sequencing of pGNB1 revealed that its backbone is very similar to that of previously se...

Background: Various medicinal plants have much efficacious value as treatment of many fatal conditions including cancer. Kigelia africana has known therapeutic efficacy in different ailments and been used traditional medicine since ages. Aim: To evaluate anticancer property any drug or plant extract HepG2 cell line. Methodology: Anticancer activity n-hexane ethanolic extracts was checked. IC50 ...
