Functional foods are foods or dietary ingredients that provide a health benefit beyond basic nutrition. A new legislation, known as the Nutrition and Health Claims Regulation, defines the legal framework for such claims within the European Union. Any claim about the nutritional or physiological effects of a product must be scientifically demonstrated. In this study, we have focused on the exploration of metabonomics as a complementary profiling technology to establish monitoring/data analysis procedures of randomized nutritional trials. More specifically, a combined intake of soybean and grapefruit in a human intervention study was analyzed with respect to both pharmacological and physiological effects. Resulting multivariate models showed a diet-induced decrease of lactate, cholesterols and triglycerides. The most drastically elevated metabolite, myo-inositol, was found to accompany a marked reduction of triglyceride levels. Suggestively, this is due to the biotransformation of myo-inositol to phosphatidylinositol, which results in a decrease of available precursors to form triglycerides. Strong inter-subject variation was present that required special attention. Dynamic modelling of collected time series data that provided the opportunity to identify slow, medium or fast responders as well as groups of subjects showing different response profiles, was also highlighted in the study. The applied strategy of time series data has proven to be a powerful complement to randomized nutritional studies adopting a clinical trial design. © 2010 Elsevier B.V.

Recently intense research identified around 4,000 single nucleotide polymorphisms (SNPs) associated with human age related diseases such as metabolic disorders. Despite their highly significant association to pathology, the functional role of these genetic variants is, in most cases, yet to be elucidated. The evolutionary distance of most animal models from humans represents a major limitation for the functional validation of these SNPs. To overcome these difficulties, HUMAN will generate mouse models carrying human hepatocytes or pancreatic cells from either primary cells (hepatocytes) or induced pluripotent stem cells (iPSCs). This innovative approach offers the unique possibility of studying function of genetic risk variants associated with metabolic diseases in an integrated living system (the mouse body), but within human-derived organs, i.e. liver and pancreas. iPSCs used to generate hepatocytes and cells will derive from extreme phenotypes, i.e. patients affected by severe metabolic diseases such as type 2 diabetes (T2D) or subjects selected for exceptional healthy longevity (subjects over 105 years and offspring of nonagenarian sibships) all fully clinically and metabolically characterised and genotyped; they will be selected according to the best combination of risk and protective alleles. We will test the effect of different nutritional regimes (e.g. high fat diet, caloric restriction), to disentangle the complex molecular mechanisms and circuitry across organs (e.g. hypothalamus-liver axis) which lead to pathology. HUMAN associates a core of outstanding basic research institutions to leading European biotech SMEs, and has the capability to produce at least 500 humanised mice. HUMAN will generate iPSCs biobanks and comprehensively manage all associated information. HUMAN is uniquely situated to drive innovation towards a better knowledge of the genetic basis of human metabolic diseases, thereby contributing to healthier aging of European citizens.

The clinical presentation of type 1 diabetes is preceded by a prodrome of beta cell autoimmunity. We probed the short period of subtle metabolic abnormalities, which precede the acute onset of diabetes in the spontaneously diabetic BB rat, by analyzing the serum metabolite profile detected with combined gas chromatography/mass spectrometry (GC/MS) and liquid chromatography/mass spectrometry (LC/MS). We found that the metabolite pattern prior to diabetes included 17 metabolites, which differed between individual diabetes prone (DP) BB rats and their age and sex matched diabetes resistant (DR) littermates. As the metabolite signature at the 40 days of age baseline failed to distinguish DP from DR, there was a brief 10-day period after which the diabetes prediction pattern was observed, that includes fatty acids (e.g. oleamide), phospholipids (e.g. phosphocholines) and amino acids (e.g. isoleucine). It is concluded that distinct changes in the serum metabolite pattern predict type 1 diabetes and precede the appearance of insulitis in spontaneously diabetic BB DP rats. This observation should prove useful to dissect mechanisms of type 1 diabetes. © 2011 Springer Science+Business Media, LLC.

2-Substituted 3-chlorobenzaldehydes were prepared from the corresponding 2-(3-chlorophenyl)-1,3-dioxolanes using an ortho-lithiation strategy. The 6-chloro-2-formylbenzamide exists only in a ring form, but 6-chloro-2- formylbenzoic acid esters were isolated in both forms as open chain and cyclic tautomers. 7-Chloro-3-hydroxy-3H-isobenzofuran-1-one reacted with nucleophilic reagents at the carbonyl or quaternary carbon depending on the character of nucleophile. © Georg Thieme Verlag Stuttgart New York.
