Abstract :

This work deals with metabolome screening of blood plasma by nuclear magnetic resonance H1-NMR. The main focus is the bio-marker discovery of T2D disease by means of NMR and pattern recognition methods. Specifically, attention is paid to data acquisition, data pretreatment, data preprocessing and multivariate analysis of metabolomics data. We propose BinPCA or what we called: ?metabogram? as a data mining approach for pre-processing data using binning method, for visualizing it using PCA and for reducing the noise and brining the group effect of metabolites using regularized sparse vector machine algorithm to discover the biological variations of metabolites measurable by NMR and other analytical methods. These biological variations in healthy individuals form a base line for detecting significant fluctuations in disease inflicted people. Inter-individual fluctuations in metabolites concentrations in the healthy people versus disease inflicted people are compared with analytical variations and found to be much smaller. In addition, variation in T2D metabolites abundance in gender?s and group age is demonstrated.
