Metabolomic profile of multiple sclerosis patients by means of 1H-NMR analysis

Multiple sclerosis (MS) is a chronic disease characterized by a high level of heterogeneity. Metabolomics is an “-omics” approach with the potential to discover new biomarkers.

Isolation, Identification, and Determination of Designer Anabolic Steroids Commonly Found in Dietary Supplements

A general analytical approach in identifying emerging steroid-like compounds is presented, including analysis by GC-MS, LC-MS, and/or HPLC-UV. Isolation of unknown compounds was achieved by high performance liquid chromatography with fraction collection. Isolated compounds were characterized by Nuclear Magnetic Resonance spectroscopy and high resolution accurate mass-mass spectrometry to elucidate their structure.

AN INTEGRATED 1H NMR, GC-MS AND HPLC-(ESI/TOF) BASED METABOLOMICS APPROACH TO THE STUDY OF ACUTE EXERCISE IN HUMAN SERUM METABOLOME

There is an increasing concern about the different response and effect that acute exercise induces on diabetic people and a novel insight into this effect can be performed using a metabolomic approach. Metabolomic is becoming widely spread used as a new and powerful tool for discerning significant changes at metabolic level. In this study we aimed to perform a non-targeted analysis and to identify metabolic differences arisen after 30 minutes of acute exercise in both young men suffering from Ty

Alignment of 1H-NMR data using a Generalized Fuzzy Hough Transform

In metabolic profiling, multivariate data analysis techniques are used to interpret 1D 1H–NMR data. Multivariate data analysis techniques require that peaks are located in the same variables in every spectrum – this requirement is not met in native NMR spectra. Current state-of-the-art alignment algorithms are unable to align peaks when the spatial order of the peaks changes. We present the Fuzzy Generalized Hough Transform alignment which solves the alignment problem.

1H NMR for the Accurate Quantification of Analytical Reference Standards

NMR can be used for the quantification of minute quantities of standard compounds. The high specificity of NMR signals permits absolute quantifications independent of the presence of impurities. The feasibility and limits of NMR application are demonstrated through the analysis of algal toxins and polar substances in butter.
