BACKGROUND Near infrared-guided indocyanine green (ICG) fluorescence has vast potential for guiding sentinel lymph node biopsy (SLNB) in patients with breast cancer. The purpose of this study was to evaluate any additional clinical benefit for SLNB when blue dye is used in combination with ICG. METHODS Between November of 2009 and September of 2013, 86 patients diagnosed with breast cancer we...

The interaction of Toluidine blue with Sodium Alginate has been investigated by spectrophotometric method. The polymer induces metachromasy in the dye as evidenced from the considerable blue shift in the absorption maxima of the dye. The interaction constant and thermodynamic parameters of polymer-dye interaction have been determined. The effect of alcohols on the reversal of metachromasy has b...

The optical sensor for "tea catechins" was built by immobilizing 2,2'-(1,4-phenylenedivinylene)bis-8-hydroxyquinoline (PBHQ) on TiO₂ nanoparticles (NPs). The sensor worked by "indophenol blue" dye formation on PBHQ-immobilized TiO₂ NPs as a result of p-aminophenol (PAP) autoxidation with dissolved O₂ at pH 10. Among quercetin, rutin, naringenin, naringin, gallic acid, caffeic acid, ferulic acid...

Pseudomonas desmolyticum NCIM 2112 was able to degrade a diazo dye Direct Blue-6 (100 mg l(-1)) completely within 72 h of incubation with 88.95% reduction in COD in static anoxic condition. Induction in the activity of oxidative enzymes (LiP, laccase) and tyrosinase while decolorization in the batch culture represents their role in degradation. Dye also induced the activity of aminopyrine N-dem...

background: one of the most important environmental pollutants is industrial wastewaters. discharging of colorful industrial effluents to receptive waters can lead to eutrification and it has the carcinogenic and mutagenic properties. therefore, the aim of this study is evaluation of acid blue 15 dye removal by dried azolla from aqueous solution. material and methods: the azolla biomass was dri...

AIMS This paper describes a simple technique of axillary and breast massage which improves the successful identification of blue sentinel nodes using patent blue dye alone. METHODS Patent blue dye was injected in the subdermal part of the retroaroelar area in 167 patients having surgical treatment for invasive breast cancer. Three stage axillary lymphatic massage was performed prior to making...

Malachite green (MG) is a fluorogenic dye that shows fluorescence enhancement upon binding to its engineered cognate protein, a fluorogen activating protein (FAP). Energy transfer donors such as cyanine and rhodamine dyes have been conjugated with MG to modify the spectral properties of the fluorescent complexes, where the donor dyes transfer energy through Förster resonance energy transfer to ...

In the present study, activated bleaching earth was used as clay adsorbent for an investigation of the adsorbability and adsorption kinetics of acid dyes (i.e., acid orange 51, acid blue 9, and acid orange 10) with three different molecular sizes from aqueous solution at 25 degrees C in a batch adsorber. The rate of adsorption has been investigated under the most important process parameters (i...

Six assays for protein in urine were compared for linearity, ease of standardization, precision, comparability of assay values, technical ease of assay, and current cost. The assays investigated were three dye-binding techniques, a recent turbidimetric technique, the trichloroacetic acid--biuret reaction, and a tannic acid protein precipitation reaction with ferric chloride. All assays suffered...

Abstract Starch-g-poly(acrylic acid)/ Pterocladia capillacea –derived activated carbon (St-g-P(AA)/P-AC) composites were prepared via aqueous solution graft copolymerization using starch, acrylic acid, and of red alga (0–10%) with N , N′ -methylenebisacrylamide crosslinker ammonium persulfate (NH 4 ) 2 S O 8 initiator. Fourier-transform infrared (FTIR) spectroscopy, Brunauer–Emmett–Teller (BET)...
