Two sensitive spectrophotometric methods are presented for the assay of pantoprazole sodium sesqui hydrate (PNT) in bulk drug and in formulations using N-bromosuccinimide (NBS) and two dyes, methyl orange and indigo carmine, as reagents. The methods involve the addition of a known excess of NBS to PNT  in acid medium, followed by determination of unreacted oxidant by reacting with a fixed a...

effects of catechin for preventing black spots forming in whiteleg shrimp (litopenaeus vannamei) were evaluated. for processing whole shrimp, catechin was used at a concentration of 0.2 and 0.3 % for 15 minutes. sodium metabisulfite was used at a concentration of 3 % for 10 minutes as control samples. without antioxidant shrimp were used as control samples too. treatments quality was evaluated ...

The method of continuous variation in conjunction with (1)H and (19)F NMR spectroscopies was used to characterize lithium and sodium enolates solvated by N,N,N',N'-tetramethylethyldiamine (TMEDA) and tetrahydrofuran (THF). A strategy developed using lithium enolates was then applied to the more challenging sodium enolates. A number of sodium enolates solvated by TMEDA or THF afford exclusively ...

Abstract INTRODUCTION Sodium MRI has been recently explored in brain tumors to potentially reveal complementary information with proton about the tumor microenvironment. However, there remains limited investigation combining sodium and quantitative techniques. This pilot study associations of diffusion-, pH-, hypoxia-weighted biomarkers gliomas. METHODS Eleven patients gliomas (n=8 IDH-wild-typ...
