MetabolomicsMetabolomic profiling of Campylobacter jejuni with resistance gene ermB by ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry and tandem quadrupole mass spectrometry
The metabolome changes of Campylobacter jejuni with resistant gene ermB remain unclear. Here, we described an untargeted metabolomic workflow based on ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry to investigate the metabolites perturbations mediated by erm...

ProteomicsIdentification of Missing Proteins in Human Olfactory Epithelial Tissue by Liquid Chromatography-Tandem Mass Spectrometry
We performed proteomic analyses of human olfactory epithelial tissue to identify missing proteins using liquid chromatography-tandem mass spectrometry. Using a next-generation proteomic pipeline with a <1.0% false discovery rate at the peptide and protein levels, we identified 3,731 proteins, among ...

MetabolomicsComputational mass spectrometry accelerates C=C position-resolved untargeted lipidomics using oxygen attachment dissociation
Mass spectrometry-based untargeted lipidomics has revealed the lipidome atlas of living organisms at the molecular species level. Despite the double bond (C=C) position being a crucial factor for enzyme preference, cellular membrane milieu, and biological activity, the C=C defined structures have no...

MetabolomicsMAVEN2: An Updated Open-Source Mass Spectrometry Exploration Platform

MAVEN, an open-source software program for analysis of LC-MS metabolomics data, was originally released in 2010. As mass spectrometry has advanced in the intervening years, MAVEN has been periodically updated to reflect this advancement. This manuscript describes a major update to the program, MA...

MetabolomicsRapid chromatography combined with trapped ion mobility mass spectrometry for analysis of derivatized small molecules
Liquid chromatography (LC) separates biomolecules based on their physicochemical properties. Reproducible retention times support compound identification, while efficient separation of structurally similar compounds is essential for accurate quantification. However, conventional LC methods are often...

MetabolomicsElucidations on the structures of some putative flavonoids identified in postharvest withered grapes (Vitis vinifera L.) by quadrupole time-of-flight mass spectrometry
Grape dehydration is an oenological process used for production of high-quality reinforced and sweet wines. High-resolution mass spectrometry (ultrahigh-performance liquid chromatography/quadrupole time-of-flight [UHPLC/QTOF]) was used to deepen the characterization of some flavonoids previously pro...
