Assessment of free fatty acid (FFA) concentration and isotopic enrichment is useful for studies of FFA kinetics in vivo. A new procedure to recover the major FFA from plasma for concentration and isotopic enrichment measurements is described and validated. The procedure involves extraction of plasma lipids with hexane, methylation with iodomethane (CH(3)I) to form fatty acid methyl esters (FAME...

This paper addresses the solution of peak overlapping, as a fundamental problem in TLC, by multivariate analysis of the images recorded by a digital camera. We report the results of our study on the application of multivariate image analysis (MIA) for simultaneous determination of several species on thin layer chromatography (TLC) sheet for the first time. An imaging system, composed of a dark ...

book through his lucid presentation of much technical data. The discussion of corrosive qualities of water is unusually thorough and explicit as is his discussion of the sanitary significance of impurities in water and on bacterial decomposition of organic matter in water. What might be considered to be a deficiency is the rather limited discussion of waterborne diseases. The liberal footnotes ...

BACKGROUND The market of hypnotic and sedative drugs is being updated due to the high toxicity barbiturates limitations their use. Currently, safer such as Z-drugs, Doxylamine, some benzodiazepine derivatives are often prescribed for treatment anxiety insomnia, but they can cause acute poisoning if overdosed or in case nonmedical AIM To establish an affordable express thin-layer chromatography ...
