  • Patent number: 8333952
    Abstract: A microfluidic radiopharmaceutical production system and process for synthesizing per run approximately, but not less than, one (1) unit dose of a radiopharmaceutical biomarker for use in positron emission tomography (PET). The radiopharmaceutical production system includes a reaction vessel that receives a radioisotope from an accelerator or other radioisotope generator. Organic and aqueous reagents are introduced into the reaction vessel, and the mixture is heated to synthesize a solution of a pre-selected radiopharmaceutical. The radiopharmaceutical solution is purified by passing the solution through a solid phase extraction column and a filter. The synthesis process produces per run a quantity of radiopharmaceutical approximately equal to, but not less than, one (1) unit dose of a radiopharmaceutical, reducing waste and allowing for the production of radiopharmaceutical on an as-needed basis.

  • Patent number: 8329142
    Abstract: Compounds, compositions and methods for the detection and diagnosis of Parkinson's disease. Derivative lycerophosphocholine (GPC) compounds are used as a detection and diagnostic aid to measure progression of Parkinson's disease by detecting GPC binding to ?-synuclein. Derivative CPG compounds including non-radioactive, paramagnetic, and radioactive derivatives of GPC are presented. These compounds possess similar binding properties to original GPC molecules and are useful in medical magnetic resonance imaging (MRI) and/or positron emission tomography (PET) applications. By employing these radiological techniques in conjunction with the compositions of the present invention, the detection, diagnosis and assessment of the progression of Parkinson's disease may be achieved.

    Abstract: This invention relates to compositions, methods utilizing fructose and other monosaccharides for the diagnosis of cancer. Cancer cells have shown a higher level of fructose utilization as compared to glucose. Further, cancer cells have shown a preferential use of fructose for nucleic acid synthesis. The present invention takes advantage of these features and provides for fructose or fructose-based compositions for the diagnosis of cancer using imaging techniques such as positron emission tomography.
