Chemometric approaches to improve PLSDA model outcome for predicting human non-alcoholic fatty liver disease using UPLC-MS as a metabolic profiling tool

Quintás, Guillermo; Portillo Poblador, Nuria; García Cañaveras, Juan Carlos; Castell, José Vicente; Ferrer, Alberto; Lahoz, Agustín (Springer Verlag (Germany), 2012-02)

An MS-based metabolomics strategy including variable selection and PLSDA analysis has been assessed as a tool to discriminate between non-steatotic and steatotic human liver profiles. Different chemometric approaches for ...
Detection of prostate cancer using a voltammetric electronic tongue

Pascual, Lluís; Campos Sánchez, Inmaculada; Vivancos, José-Luis; Quintás, Guillermo; Loras Monfort, Alba; Martínez-Bisbal, M.Carmen; Martínez-Máñez, Ramón; Boronat-Tormo, Francisco; Ruiz Cerda, Jose Luis (Royal Society of Chemistry, 2016)

[EN] A simple method based on the multivariate analysis of data from urine using an electronic voltammetric tongue is used to detect patients with prostate cancer. A sensitivity of 91% and a specificity of 73% were obtained ...
Evaluation of the effect of chance correlations on variable selection using Partial Least Squares -Discriminant Analysis

Kuligowski, Julia; Pérez Guaita, David; Escobar, Javier; Guardia, Miguel de la; Vento, Máximo; Ferrer Riquelme, Alberto José; Quintás, Guillermo (Elsevier, 2013-11-15)

Variable subset selection is often mandatory in high throughput metabolomics and proteomics. However, depending on the variable to sample ratio there is a significant susceptibility of variable selection towards chance ...
Towards the potential use of (1)H NMR spectroscopy in urine samples for prostate cancer detection

Zaragozá Torres, Patricia; Ruiz Cerda, Jose Luis; Quintás, Guillermo; Gil Grau, Salvador; Costero Nieto, Ana María; León, Zacarías; Vivancos, José-Luis; Martínez Mañez, Ramón (Royal Society of Chemistry, 2014-08-21)

A simple method based in multivariate analysis of 1H NMR spectra profiles of urine samples can be used to detect patients with prostate cancer.
