Metabolomics
. 2015 May;
11(3):753-763.
PMID: 25960696
Quantitative biases in the abundance of precursor and product ions due to mass discrimination in RF-only ion guides results in inaccurate collision induced dissociation (CID) spectra. We evaluated the effects...

J Chem Inf Model
. 2015 Feb;
55(3):709-18.
PMID: 25668446
Metabolic pathways are composed of a series of chemical reactions occurring within a cell. In each pathway, enzymes catalyze the conversion of substrates into structurally similar products. Thus, structural similarity...

Curr Comput Aided Drug Des
. 2015 Jan;
10(4):374-82.
PMID: 25549758
A novel approach is developed for modeling situations in which the modeled property is an algebraically transformed version of the original experimental data. In many cases such a transformation results...

Anal Chem
. 2014 Dec;
87(2):1137-44.
PMID: 25495617
Despite recent advances in analytical and computational chemistry, lipid identification remains a significant challenge in lipidomics. Ion-mobility spectrometry provides an accurate measure of the molecules' rotationally averaged collision cross-section (CCS)...

Comput Struct Biotechnol J
. 2014 Apr;
5:e201302005.
PMID: 24688698
The identification of compounds in complex mixtures remains challenging despite recent advances in analytical techniques. At present, no single method can detect and quantify the vast array of compounds that...

J Chem Inf Model
. 2013 Sep;
53(9):2483-92.
PMID: 23991755
Current methods of structure identification in mass-spectrometry-based nontargeted metabolomics rely on matching experimentally determined features of an unknown compound to those of candidate compounds contained in biochemical databases. A major...
