NMR, Metabonomics and Molecular Profiles: Applications to the Quality Assessment of Foodstuffs
Nuclear Magnetic Resonance (NMR) is a branch of spectroscopy that is based on the fact that many atomic nuclei may be oriented by a strong magnetic field and will absorb radiofrequency radiation at characteristic frequencies. The parameters that can be measured on the resulting spectral lines (line …

Multivariate analysis of metabonomic data
Metabonomics is one of the main technologies used in biomedical sciences to improve understanding of how various biological processes of living organisms work. It is considered a more advanced technology than e.g. genomics and proteomics, as it can provide important evidence of molecular biomarkers …

Quantitative analysis and metabonomic study of phytoestrogens in Africans
… including location, gender and age. 1H NMR-metabonomics was performed on the collected bio-fluids to investigate soy - phytoestrogens' effects on specific endogenous metabolites involved in major metabolic processes. Twenty-two endogenous metabolites were quantified using Chenomx® NIVIR …

Toxicity and biotransformation of 1,1,1,3,3-Pentafluoropropane, 3,3,3-Trifluoropropionic acid and 1,1,1,3-Tetrachloropropane
The biotransformation of 1,1,1,3,3-pentafluoropropane was investigated in rats and in in vitro systems. First, the metabolites were identified in vivo using GC/MS and 19F NMR analysis. The main metabolite was identified as trifluoroacetic acid, the minor metabolite as 3,3,3-trifluoropropionic acid …

Defining the metabolic effect of peroxisome proliferator-activated receptor δ activation
Peroxisome proliferator-activated receptors (PPARs) are nuclear receptors that function as ligand activated transcription factors. There are three identified isotypes: PPAR alpha, PPAR gamma and PPAR delta, together controlling the expression of genes involved in inflammation, cell differentiation, …

Biochemistry in healthy and neoplastic human tissues: metabolic alteration revealed by HR-MAS nuclear magnetic resonance spectroscopy
… and it has become very important for integrated metabonomics studies. The objective is to identify metabolites that can be used as markers for the discrimination of the different types of cancer, for the grading, and for the assessment of the evolution of the tumour. Furthermore, an attempt to …
