Glucokinase from Bacillus stearothermophilus was irreversibly inactivated by the reactive dichlorotriazinyl dye Procion Blue MX-3G at pH 8.0. The enzyme was protected from inactivation by the substrate MgATP. Kinetic data implied that the dye occupied the MgATP-binding site. The apparent Km values for MgATP and D-glucose were found to be 70 microM and 210 microM respectively, and the Kd of the ...

Experiments were performed to determine the extent of penetration of drill water into Grouse Canyon densely welded t ff during use of normal drilling practices. Core samples were examin d from a borehole cored in a rib of the Rock Mechanics drift in G Tunnel at the Nevada Test Site, Nye County, Nevada. Methylene blu dye was added to the drill water to act as a tracer which stained the rock blue...

The possible utilization of rice husk activated carbon as an adsorbent for the removal of methylene blue dye from aqueous solutions has been investigated. In this study, activated carbons, prepared from low-cost rice husk by sulfuric acid and zinc chloride activation, were used as the adsorbent for the removal of methylene blue, a basic dye, from aqueous solutions. Effects of various experiment...

PURPOSE Near-infrared fluorescence imaging with indocyanine green (ICG) has the potential to improve sentinel lymph node (SLN) mapping in breast cancer. In this clinical trial, we compared the potential value of ICG combined with blue dye with that of blue dye alone for detecting SLNs. METHODS Patients undergoing SLN biopsy (SLNB) between November 2010 and November 2013 were included. Up to D...

This study investigated the efficiency of electerocoagulation (EC) in removing color from synthetic and simulated textile wastewater. The study on decolorization of mixed dyes is a step toward an effective treatment of textile wastewater. Two representative reactive dye molecules were selected for the synthetic dye wastewater, a blue dye alone and mixed dye (black, blue, red, 1:1:1v/v). The EC ...

Although the potency of trypan blue as a teratogenic agent in rodents has been known for almost twenty years the mechanism of its action remains obscure. The dye produces a variety of biological effects (see review by Beck & Lloyd, 1966) and most of these have at some time been suggested as possibly relevant to its teratogenicity. The investigation of such correlations would clearly be assisted...

two potassium oxalate doped tio2 samples, designated as k1-tio2 and k2-tio2, were synthesized by the base-catalyzed sol-gel process. these samples were impregnated into rubber sheets. two commercial tio2 samples, anatase and degussa p25, were used as reference materials with which the synthesized samples were to be compared. anatase and p25 were also impregnated into rubber sheets and designate...

Selective polymeric extractants were prepared for preconcentration of Cibacron reactive red dye, a dye that is often applied with Cibacron reactive blue and Cibacron reactive yellow for dyeing of fabrics. The best extractant was fabricated (in chloroform) using methacrylic acid (as monomer), ethylene glycol dimethacrylate (as crosslinker), AIBN (as initiator for polymerization), and red dye as ...

UNLABELLED Colloidal radiopharmaceuticals are commonly used in combination with blue dye for localization of the sentinel node. Liposomes are colloidal particles composed of spontaneously forming lipid spheres that can carry a wide variety of diagnostic and therapeutic agents. Conventional liposomes are poorly retained in lymph nodes (<2% of the subcutaneously injected dose). We have previously...

OBJECTIVE To determine whether intraoperative lymphatic mapping with isosulfan blue dye and sentinel lymph node biopsy accurately demonstrates the pathway of regional metastases from mucosal sites in squamous cell carcinoma of the head and neck. DESIGN A prospective clinical study of intraoperative lymphatic mapping. SETTING An academic tertiary referral center. PATIENTS Patients with pre...
