the present work reports a kinetic spectrophotometric method for the determination of traceamounts of sulphite that is based on inhibitory effect of sulphite on the oxidation of methyleneblue (mb) in acidic media. the reaction is followed spectrophotometrically by monitoring thedecrease in absorbance of mb at 664 nm with a fixed time of 0.5-4.5 minutes. it was found thatsulphite exert a strong ...
© 2017 Asian Journal of Transfusion Science | Published by Wolters Kluwer ‐ Medknow Sir, A 29‐year‐old male patient with carcinoma of the gastroesophageal junction was posted for transhiatal esophagectomy. Intraoperatively, 2 units of packed red cells were ordered for transfusion to the patient and were issued to the patient as per the departmental standard operating procedure including pretran...
In 2009, Blue Cross Blue Shield of Massachusetts implemented a global budget-based payment system, the Alternative Quality Contract (AQC), in which provider groups assumed accountability for spending. We investigate the impact of global budgets on the utilization of prescription drugs and related expenditures. Our analyses indicate no statistically significant evidence that the AQC reduced the ...
background: helicobacter pylori, which is associated with many upper gastrointestinal diseases, is found in half of the population of the world. several special stains and immunohistochemistry stain for h. pylori are available. the need for and usefulness of immunohistochemical (ihc) technique has been debated for years. toluidine blue is a simple stain for microbiological studies and is easily...
fertilizer plant waste carbon slurry has been investigated after some processing as an adsorbent for the removal of dyes and phenols using columns. the results show that the carbonaceous adsorbent prepared from carbon slurry being porous and having appreciable surface area (380 m2/g) can remove dyes both cationic (meldola blue, methylene blue, chrysoidine g, crystal violet) as well as anionic (...
Three rapid spectrophotometric methods were developed for the determination of sunitinib based on the formation of ion-pair complex in acidic medium with bromocresol purple, bromothymol blue, and bromophenol blue. The formed ion-pair complexes, extractable with chloroform, were measured at 422 nm for bromocresol purple, 425 nm for bromothymol blue and 427 nm for bromophenol blue. All these meth...
One of the famous dyes is methylene blue (MB) which is a symbol of hazardous dyes. In this research, methylene blue was adsorbed using the blends of saffron petals with activated carbon. Five independent variables involving pH (2-13), contact time (5-270 min), saffron petals powder dosage (0.1-10 g/l), initial concentration of methylene blue solution (20-300 ppm) and activated carbon dosage (0....
