Replacement of barbiturate buffer by a tris-hydroxymethylaminomethane buffer in the thymol test reagent of Maclagan greatly improves the stability of the reagent. Thymol turbidity measurements made by means of the modified reagent agreed closely with those made with barbiturate-containing reagents. However in hyperlipemic sera, the latter reagent gave higher turbidities. A reaction of barbitura...

Three reagents for detecting indole, Kovac, Ehrlich, and p-dimethylaminocinnamaldehyde (DMCA), were evaluated with commercial microtest systems for characterizing and identifying anaerobic bacteria. The DMCA reagent, the most sensitive of the three reagents, gave a positive reaction with 445 of 449 strains of various indole-producing anaerobic bacteria. There was 99.6% agreement between the res...

We describe the use of electrogenerated reactants for continuous on-line reaction detection with thin-layer hydrodynamic amperometry. The reagent is introduced into the liquid-chromatographic column effluent at a constant rate by using controlled-current electrochemistry. After the effluent passes through a short reaction coil, the reagent concentration is monitored at the detector. Reaction of...

TLR signaling is associated with the transcription of various proinflammatory cytokines, including TNF-α, IL-6, and IL-1β. After transcription, the mRNA of these proinflammatory cytokines needs to be tightly controlled at the posttranscriptional level to achieve an optimal expression. However, the precise mechanism of posttranscriptional regulation is not fully understood. In the current study,...

Abstract In this study, the Fenton/adsorption of dye effluent containing Levafix blue has been carried out via a cost-efficient and eco-friendly heterogeneous Fenton solar-Fenton methods. Alum sludge, water treatment by-product were successfully collected calcined to 400 °C (AS400) tested for use as catalyst in process. X-ray diffraction, Scanned electron microscopy techniques applied investiga...

We describe a modified glucose oxidase reagent for use in the polarographic determination of glucose with the Beckman "Glucose Analyzer." The reagent contains 1 mL/L of a surfactant (Brij-35 250 g/L solution) as the wetting agent instead of glycerol. Precipitation of components associated with the formulation recommended by Fischl et al. [Clin. Chem. 21, 760 (1975)] does not occur with this rea...

Abstract Organic electrochemistry is a technique that allows for the heterogeneous redox reactions avoiding both use of stoichiometric amounts reagents and resulting formation by-products. In fact, reagent in these electron, which naturally eco-friendly produces no side compounds. It therefore quite obvious can be classified as “green” technology. The this methodology synthesis β-lactams not no...
