International journal of molecular sciences
Mar 7, 2018
Colorectal cancer (CRC) is one of the most daunting diseases due to its increasing worldwide prevalence, which requires imperative development of minimally or non-invasive screening tests. Urinary polyamines have been reported as potential markers to...
Detection of potential new biomarkers of atherosclerosis by probe electrospray ionization mass spectrometry.
Metabolomics : Official journal of the Metabolomic Society
Feb 27, 2018
INTRODUCTION: Atherosclerotic diseases are the leading cause of death worldwide. Biomarkers of atherosclerosis are required to monitor and prevent disease progression. While mass spectrometry is a promising technique to search for such biomarkers, it...
Simultaneous determination of TPN729 and its five metabolites in human plasma and urine by liquid chromatography coupled to tandem mass spectrometry.
Journal of pharmaceutical and biomedical analysis
Dec 30, 2017
A specific and sensitive method was firstly developed using high performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS) to simultaneously quantify TPN729 and its metabolites (TPN729-D1, TPN729-D2, TPN729M15-3 and TPN729M...
Development of an improved sample preparation platform for acidic endogenous hormones in plant tissues using electromembrane extraction.
Journal of chromatography. A
Dec 30, 2017
Despite their importance in pivotal signaling pathways due to trace quantities and complex matrices, the analysis of plant hormones is a challenge. Here, to improve this issue, we present an electromembrane extraction technology combined with liquid ...
Determination of IMM-H004 and its active glucuronide metabolite in rat plasma and Ringer's solution by ultra-performance liquid chromatography-tandem mass spectrometry.
Journal of chromatography. B, Analytical technologies in the biomedical and life sciences
Dec 29, 2017
IMM-H004 is a novel neuroprotective agent and its glucuronide metabolite IMM-H004G has similar protective effects against cerebral ischemic injury in vivo and in vitro. A specific and sensitive ultra-performance liquid chromatography-tandem mass spec...
2-methyl butyramide, a previously identified urine biomarker for Ascaris lumbricoides, is not present in infected Indonesian individuals.
Parasites & vectors
Dec 29, 2017
UNLABELLED: ᅟ: Previous reports suggest that the 2-methyl butyramide and 2-methyl valeramide metabolites of Ascaris lumbricoides in urine of infected individuals could be considered as urinary biomarkers for active infection. We have developed an LC-...
A simple LC-MS/MS method for determination of deferasirox in human plasma: Troubleshooting of interference from ferric ion in method development and its application.
Journal of pharmaceutical and biomedical analysis
Dec 28, 2017
As an orally active iron chelator, deferasirox forms its ion complexes in the prepared plasma samples and LC-MS mobile phase where ferric ion exists, and then comparing with the nominal concentration level, a lower detected concentration level of def...
