Patent application numberDescriptionPublished
20080277578Nanoporous substrates for the analytical methods - Nanoporous materials can be used to enrich samples for subsequent analysis of substances contained in the sample. The method is shown to enrich the yield of species in the low molecular weight proteome, allowing detection of small peptides in the low nanomolar range.11-13-2008
20090087346Method for Harvesting Nanoparticles and Sequestering Biomarkers - Capture particles for harvesting analytes from solution and methods for using them are described. The capture particles are made up of a polymeric matrix having pore size that allows for the analytes to enter the capture particles. The pore size of the capture particles are changeable upon application of a stimulus to the particles, allowing the pore size of the particles to be changed so that analytes of interest remain sequestered inside the particles. The polymeric matrix of the capture particles are made of co-polymeric materials having a structural monomer and an affinity monomer, the affinity monomer having properties that attract the analyte to the capture particle. The capture particles may be used to isolate and identify analytes present in a mixture. They may also be used to protect analytes which are typically subject to degradation upon harvesting and to concentrate low an analyte in low abundance in a fluid.04-02-2009
20090148961SMART HYDROGEL PARTICLES FOR BIOMARKER HARVESTING - Capture particles for harvesting analytes from solution and methods for using them are described.

20090305432Polypeptide Molecular Switch - A polypeptide can conduct electricity in a closed circuit. Conformational changes in the polypeptide due to posttranslational modifications or ligand binding can effect the conductive properties of the polypeptide which can be measured. In such a closed circuit, a polypeptide having at least one residue capable of reversible modification can be used as a molecular switch. Circuits comprising such molecular switches can be used, for example, in methods for assessing the modification state of a polypeptide, determining the activity of an enzyme of interest, identifying compounds that affect the activity of an enzyme of interest, storing data, detecting the presence of a compound and identifying inhibitors of protein-protein interactions.12-10-2009
20100105087BIOMARKERS FOR BREAST CANCER - Low molecular weight (LMW) peptides have been discovered that are indicative of breast cancer. Evaluating patient samples for the presence of such LMW peptides is an effective means of detecting breast cancer and monitoring the progression of the disease, for example during treatment. The LMW peptides are particularly useful in detecting breast cancer during its early stages.04-29-2010
20100143949BIOMARKERS FOR COLORECTAL CANCER - Low molecular weight (LMW) peptides have been discovered that are indicative of colorectal cancer. Evaluating patient samples for the presence of such LMW peptides is an effective means of detecting colorectal cancer and monitoring the progression of the disease. The LMW peptides are particularly useful in detecting colorectal cancer during its early stages.06-10-2010
20100240543Method of isolating analytes from a sample - The current invention is a capture-particle comprising: a) a molecular sieve portion; and b) an analyte binding portion; wherein the molecular sieve portion, analyte binding portion or both further comprise a cross-linked region having modified porosity. Capture particles wherein the molecular sieve portion, analyte binding portion or both comprise pore dimensions sufficient to exclude molecules larger than about 60 kDa. These particles are useful in purification and diagnostic methods. Kits comprising the capture particles are also described.09-23-2010
20100298157PHOSPHOPROTEOMIC EVALUATION OF DIABETES AND OBESITY - A subject's likelihood of responding to bariatric surgery can be assessed by measuring the phosphorylation state of certain proteins found in white adipose tissue (WAT). In particular, measuring the phosphorylation state of particular proteins can predict a patient's likelihood of resolving diabetes mellitus following bariatric surgery. In addition, evaluating the phosphorylation state of certain proteins forecasts a patient's capacity to reduce excess body weight and/or waist size following bariatric surgery. Such tests are valuable tools for managing the diseases of diabetes and obesity and determining who would most likely benefit from bariatric surgical procedures such as gastic bypass surgery.11-25-2010
20110104065GENETIC ALTERATION ASSOCIATED WITH PRE-MALIGNANT CANCER - Described herein are progenitor cancer cells and cell lines isolated from human breast ductal carcinoma in situ (DCIS) lesions and the uses of these cells or cell lines in drug design, drug screening, and monitoring in vivo therapy. The DCIS malignant precursor cells or cell lines are epithelial in origin, are positive for markers of autophagy, show at least one genetic difference from normal cells of said fragment, form 3-D tube-like structures or ball aggregates, or are inhibited in formation of 3-D structures and migration by treatment with chloroquine. In one embodiment, there is a loss of heterozygosity (LOH) that is narrowly confined to a region of chromosome 6p (6p21.1-6p12.3) that contains the SUPT3H gene.05-05-2011
20110137627METHOD AND SYSTEM FOR HOMOLOGOUS CONTROL OF NETWORKS - A system and method for creating at least one new network, comprising: selecting at least one node and at least one set of reactions where reagents in each reaction of the at least one set of reactions are known in at least one reference network; and creating at least one new network by causing the at least one new network to behave in a similar way with respect to the at least one node and the at least one set of reactions as the at least one reference network reacts with the at least one node and the at least one set of reactions.06-09-2011
