ABSTRACT

Liquid chromatography tandem mass chromatography (LC-MS/MS) is an important hyphenated technique for quantitative analysis of drugs in biological fluids. Because of high sensitivity and selectivity, LC-MS/MS has been used for pharmacokinetic studies, metabolites identification in the plasma and urine. This manuscript gives comprehensive analytical review, focusing on chromatographic separation approaches (column packing materials, column length and mobile phase) as well as different acquisition modes (SIM, MRM) for quantitative analysis of glucocorticoids and stimulants. This review is not meant to be exhaustive but rather to provide a general overview for detection and confirmation of target drugs using LC-MS/MS and thus useful in the doping analysis, toxicological studies as well as in pharmaceutical analysis.

ABSTRACT

Helicobacter pylori is a major human pathogen and its transmission and epidemiology have been extensively studied; it has been found that H. pylori's prevalence and infection outcome is characterized by marked differences between the developing and the developed worlds. Recent data on genomic analyses and comparative core genome haplotyping have revealed that H. pylori has coevolved with its human host. While several studies advocate the protective effects of H. pylori colonization, it is prudent to systematically unleash the role of the strong virulence apparatus present within most H. pylori strains and to determine how to disarm them [or protect the host from the effects] if the intent is to allow it to remain a friendly organism or to use it as a vaccine delivery tool. While genotyping and phenotyping based on a few genetic markers have not provided much insight into such issues, use of replicate/chronological genomics [of virulent versus innocuous strains] coupled with functional screens in animal models is expected to be able to explain the acquisition and evolution of virulence factors of H. pylori and their discreet associations with serious clinical outcomes such as gastric cancer
