“…The collinearity of the measured variables complicates this analysis. 91 Sample acquisition, analysis, preprocessing and identi cation will be described in detail in the following chapters. Final biological interpretation depends on online databases of molecular pathways and interactions, previous research, and intimate knowledge of the system and disease under study.…”

“…This is because an NMR profile contains qualitative and quantitative information on the hundreds of different small molecules present in a sample at Ͼ1 M concentration (21). Moreover, NMR-based metabolomics makes no assumption on the identity of the metabolites that are relevant for the selected pathology, because information on the significant metabolic pattern alterations is directly obtained through statistical analysis of the NMR profiles (22,23).The present work describes a combined approach based on quantitative PCR (qPCR) of bacterial 16S rRNA genes and metabolomics to characterize the vaginal environment of women affected by BV as well as to search for modifications induced by the administration of different dosages of rifaximin vaginal tablets. To the best of our knowledge, this is the first work describing the vaginal environment through a metabolomic approach based on NMR, as well as the first describing, by means of this technique,…”
