INTRODUCTION Peak and trough serum concentrations of vancomycin were determined in term newborn infants with confirmed or suspected Staphylococcus sp sepsis by high performance liquid chromatography and flourescence polarization immunoassay. OBJECTIVE To statistically compare the results of the high performance liquid chromatography and flourescence polarization immunoassay techniques for mea...

Background and Objectives: Furfural (F) and hydroxymethyl furfural (HMF) are cyclic aldehydes, which are formed during the heat processing of foods. These chemical contaminants have received much attention due to their suspected health hazards and heat damage indicators. The aim of the present study was extraction and determination of F and HMF in baby-foods using dispersive liquid-liquid micro...

Chemical modification of target analytes is widely used in modern analytical methods. This review focuses on the application of chemical modification techniques is the simultaneous analysis of metallic species by capillary electrophoresis, liquid chromatography and gas chromatography. Emphasis is placed on the procedures relating to analyses carried out by capillary electrophoresis. The develop...

stachys lavandulifolia vahl is an herbaceous wild plant native to iran which is traditionally used in iranian folk medicine as a mild sedative tea for reducing anxiety and for treatment of gastrointestinal disorders. our previous study on ethyl acetate extract of s. lavandulifolia proved anti-anxiolytic activity and so the present study was designed to determine chemical components of this biol...

Some studies reported the presence chemicals are deliberately added to Jamu. Jamuthat containing usually had a faster healing effect compared do not contain chemicals. cause serious...

in this study, for the analysis of human urine samples, a novel method explained for the determination of celecoxib, a nonsteroidal anti-inflammatory drug (nsaid), using molecularly imprinted solid-phase extraction (mispe) coupled with high-performance liquid chromatography (hplc). the synthesis of the mip was performed by precipitation polymerization in methacrylic acid (maa), ethylene glycol ...
