As there are sparse data on the impact of growth media on the phenomenon of biofilm development for Candida we evaluated the efficacy of three culture media on growth, adhesion and biofilm formation of two pathogenic yeasts, Candida albicans and Candida tropicalis. The planktonic phase yeast growth, either as monocultures or mixed cultures, in sabouraud dextrose broth (SDB), yeast nitrogen base...
A mesoporous hybrid silicate microsphere with superior adsorption performance has been successfully synthesized by employing an "all-into-one" strategy and a simple one-pot hydrothermal process using naturally abundant low-grade red palygorskite (PAL) clay as raw material in the presence of non-toxic SiO32- and Mg2+ ions. As is expected, both the PAL and associated minerals transformed into a n...
The classification of Barrett esophagus (BE) using magnifying endoscopy with narrow band imaging (ME-NBI) is not widely used in clinical settings because of its complexity. To establish a new simplified available classification using ME-NBI.We conducted a cross-sectional study in a single-referral center. One hundred eight consecutive patients with BE using ME-NBI and crystal violet (CV) chromo...
A novel immunoassay based on surface-enhanced Raman scattering (SERS) has been developed. The method exploits the SERS-derived signal from reporter molecules (crystal violet, CV) encapsulated in antibody-modified liposome particles. The antigen is firstly captured by the primary antibody immobilized in microwell plates and then sandwiched by secondary antibody-modified liposome. The CV molecule...
The detection of bifenthrin is closely related to the adsorption SERS substrates. In this study, superparamagnetic Fe3O4@Au MNPs coated with GO were used detect and enrichment molecules benzene rings. Firstly, thermal solvent method synthesized Fe3O4 magnetic nanoparticles (MNPs) a particle size ~250 nm. Next, polyethylene imide (PEI) was as an intermediate layer modify surface form positively ...
Nutraceutical industrial fenugreek seed spent (NIFGS), a relatively low-cost material abundantly available with little toxicity is used in crystal violet (CV) dye remediation from aqueous media and reported the present study. To access adsorption capacity, factors affecting it are kinetics equilibrium thermodynamics. All experiments were designed at approximately pH 7. The isotherm model propos...
Surface active agents (SAA) with negative charge of polar group are named as anionic compounds. They are the main constituent of most products containing synthetic surfactants. Anionic surfactants after use are passed into sewage-treatment plants, where they are partially degraded and adsorbed to sewage sludge. Therefore, it is important to investigate the environmental fate of those classes of...
AIM OF THE STUDY The aim of the work was to determine the influence of tyrphostin AG1296, an inhibitor of platelet-derived growth factor receptor (PDGFR) tyrosine kinase, on autocrine growth of rhabdomyosarcoma (RMS) cells. MATERIALS AND METHODS RMS cells were cultured in serum-free DMEM/F12 medium. Modified crystal violet (CV) and MTT methods were used to determine the RMS cells' proliferati...
Through in-situ reduction of silver nitrate without using any coupling-agent, a substrate for surface-enhanced Raman scattering (SERS) was prepared by coating silver on hollow buoyant silica microspheres as a lab on a bubble (LoB). The silver coated LoBs (LoBs@Ag) floated on surface of a solution could provide a very convenient platform for the detection of target molecules in the solution. The...
Consumption of meat contaminated with Yersinia pestis can cause oropharyngeal plague in humans. Existing microbiological media designed for selective detection of Y. pestis in food are not satisfactory for that purpose. Expression of genetic determinants in Yersinia species including low calcium response (Lcr), colony size, crystal violet (CV) binding, Congo red (CR) uptake, autoagglutination (...
