Abstract: Disclosed is a class of compounds which inhibit the enzymatic conversion of fructose-lysine into fructose-lysine-3-phosphate in an ATP dependent reaction in a newly discovered metabolic pathway. According to the normal functioning on this pathway, fructose-lysine-3-phosphate (FL3P) is broken down to form free lysine, inorganic phosphate and 3-deoxyglucosone (3DG), the latter being a reactive protein modifying agent. 3DG can be detoxified by reduction to 3-deoxyfructose (3DF), or it can react with endogenous proteins to form advanced glycation end-product modified proteins (AGE-proteins) Also disclosed are therapeutic methods of using such inhibitors to alleviate deleterious effects of 3DG.

Abstract: Systems and methods for blood flow and perfusion measurement using complex amplitude modulation of MRI pulses are presented. In exemplary embodiments of the disclosed subject matter, inflowing arterial spins can be modulated using a complex modulation function having certain mathematical properties in the frequency domain, such as, for example, a pseudo-random sequence. In exemplary embodiments of the disclosed subject matter the mathematical properties of such complex modulation functions can be used to measure individual transit times by deconvolving them from a series of acquired images. In exemplary embodiments of the disclosed subject matter images can be acquired at the same rapid rate as arterial modulation, and transit time distribution in the imaged tissue can be determined as part of a single integrated acquisition.

Abstract: The invention includes a computer implemented process to identify at least one pattern and its distribution in a set of data for the purpose of interpreting the data. The process comprises (a) representing a set of data by an original data matrix D residing in a storage device, and; (b) decomposing the set of data into a set of patterns represented by a matrix F and their distribution represented by a matrix A, wherein the matrix F represents the set of patterns needed to describe the data and the matrix A represents the distribution of the set of patterns within the data matrix D, the decomposing comprising performing a Bayesian-based Monte Carlo calculation using at least the data matrix D to determine the matrices A and F, wherein the matrices A and F reconstruct the data matrix D and are more amenable to analysis than the data matrix D. Application of the process to environmental, biological and medical, econometric, and other fields is included in the invention.

Abstract: The present invention is based on the discovery of a metabolic pathway in which a specific kinase converts fructose-lysine into fructose-lysine-3-phosphate in an ATP dependent reaction. Fructose-lysine-3-phosphate (FL3P) is then broken down to form free lysine, inorganic phosphate and 3-deoxyglucosone (3DG), the latter being a reactive protein modifying agent. 3DG can be detoxified by reduction to 3-deoxyfructose (3DF), or it can react with endogenous proteins to form advanced glycation end-product modified proteins (AGE-proteins), which are believed to be a cause of diabetic complications. Disclosed is a class of compounds which inhibit the action of FL3P kinase in the above-mentioned pathway.

Abstract: Concentrations of one or more carbohydrates phosphorylated at a secondary hydroxyl, including fructose-3-phosphate and sorbitol-3-phosphate, in biological tissue or cells of diabetic patients are determined by .sup.31 P NMR Spectroscopy, High Performance Liquid Chromatography (HPLC) or other appropriate analytical techniques. Elevated levels of such phosphorylated carbohydrates, relative to a prescribed standard or threshold level, are associated with an increased risk for developing the degenerative complications of diabetes. A method is provided for determining the relative concentrations of such phosphorylated carbohydrates, whereby the relative risk of a patient for the development of diabetic complications and the efficacy of therapeutic intervention in prevention of such complications may be assessed.

Abstract: Imaging of 1-, 2-, or 3-dimensional specimens is effected based on nuclear magnetic resonance of a chemical species. A specimen is placed in an essentially constant magnetic field H.sub.o, exposed to an electromagnetic pulse, and exposed to an an additional magnetic field H.sub.1 whose strength is linearly increasing across the specimen. A free induction decay signal is sampled after field H.sub.1 is turned off, and sample values are stored for later processing. These steps are carried out repeatedly for different fields H.sub.1, and stored sample values are Fourier transformed into desired frequency spectra at points in the specimen.
