Mass Spectrometry Fingerprints of Small-Molecule Metabolites in Biofluids. Building a Spectral Library of Recurrent Spectra for Urine Analysis.

August 19, 2019
Author(s)
Yamil Simon, Ramesh Marupaka, Xinjian Yan, Yuxue Liang, Kelly H. Telu, Yuri A. Mirokhin, Stephen E. Stein
A large fraction of ions observed in electrospray liquid chromatography-mass spectrometry (LC-MS) experiments of biological samples remain unidentified. One the main reasons for this is that spectral libraries of pure compounds fail to account for the

A large fraction of ions observed in electrospray liquid chromatography–mass spectrometry (LC–ESI-MS) experiments of biological samples remain unidentified. One of the main reasons for this is that spectral libraries of pure compounds fail to account for

Pairwise Alignment of Chromatograms using a Fisher-Rao Metric

September 2, 2014
Author(s)
William E. Wallace, Anuj Srivastava, Kelly H. Telu, Yamil Simon
A new approach to aligning chromatograms is introduced and applied to examples of metabolite identification by liquid chromatography mass spectrometry (LC MS). A square root representation of the chromatogram’s derivative coupled with a Fisher Rao

Yamil Simon, Mark S. Lowenthal, Lisa E. Kilpatrick, Maureen L. Sampson, Kelly H. Telu, Paul A. Rudnick, William G. Mallard, Daniel W. Bearden, Tracey B. Schock, Dmitrii V. Tchekhovskoi, Niksa Blonder, Xinjian Yan, Yuxue Liang, Yufang Zheng, William E. Wallace, Pedatsur Neta, Karen W. Phinney, Alan T. Remaley, Stephen E. Stein
Recent progress in metabolomics and the development of increasingly sensitive analytical techniques have renewed interest in global profiling, i.e., semi-quantitative monitoring of all chemical constituents of biological fluids. In this work, we have
