spectrometric techniques for the analysis of trace lead have developed rapidly due to the increasing need for accurate measurements at extremely low levels of this element in diverse matrices. this review covers separation and preconcentration procedures, and considers the features of the application with several spectrometric techniques. the use of an appropriate sample handling technique is a...

conclusions cd5l might be a useful biomarker for early diagnosis of hcc in hcv cirrhotic patients. lrg and hp α2 isoforms could be potential markers for distinguishing viral hcc. our results also further support the presence of varying molecules involved in hepatocarcinogenesis in hbv when compared with hcv infection. patients and methods two-dimensional polyacrylamide gel electrophoresis combi...

Chromatography coupling to mass spectrometry becomes a vital instrumentation tool for the separation and determination of small molecules qualitatively and quantitatively. In this study, the author is focused on the mitragynine and 7hydroxymitragynine. Mitragynine and its major metabolite, 7-hydroxymitragynine (also known as “kratom”), are drugs which extracted from a tree planted in Thailand, ...
