This work aims to evaluate the potential of H Nuclear Magnetic Resonance (NMR) spectroscopy combined with multivariate statistics (metabonomics) for finding malignancy biomarkers in lung tissue and discriminating between different tumour histological types. Paired tissue samples from 32 patients with primary lung cancer were directly analysed by H High Resolution Magic Angle Spinning (HRMAS) NM...

The health of animals, including humans, is dependent on their resident microbiota, but the complexity of the microbial communities makes these associations difficult to study in most animals. Exceptionally, the microbiology of the pea aphid Acyrthosiphon pisum is dominated by a single bacterium Buchnera aphidicola (B. aphidicola). A (1)H NMR-based metabonomic strategy was applied to investigat...

Stress in the form of moderate periods of maternal separation of newborn rats has been postulated to cause permanent changes in the central nervous system and diseases in later life. It is also considered that dietary supplementation with long chain polyunsaturated fatty acids (LC-PUFAs) can potentially ameliorate the effects of stress. The metabolic consequences of early life maternal separati...

Inflammatory bowel diseases (IBD) including Crohn's disease (CD) and ulcerative colitis (UC) have a major impact on the health of individuals and populations. Accurate diagnosis of inflammatory bowel disease (IBD) at an early stage, and correct differentiation between Crohn's disease (CD) and ulcerative colitis (UC), is important for optimum treatment and prognosis. We present here the first ch...

There is increasing evidence that biomarkers of exhaled gases or exhaled breath condensate (EBC) may help in detecting abnormalities in respiratory diseases mirroring increased, oxidative stress, airways inflammation and endothelial dysfunction. Beside the traditional techniques to investigate biomarker profiles, "omics" sciences have raised interest in the clinical field as potentially improvi...

Plasma obtained from three strains of Zucker rats was analysed using capillary gas chromatography/mass spectrometry (GC/MS) to obtain global metabolite profiles as part of a series of metabonomic investigations of animal models of diabetes. Samples were obtained from 20-week-old male wild-type Zucker lean, (fa/fa) obese and lean/(fa) animals and were analysed following protein precipitation, us...
