  • Publication number: 20190365921
    Abstract: A system and method configured to achieve hydrogel particle treatment for the reduction of metastatic burden in an immunocompetent syngeneic mouse model is described. The system seeks to achieve methodic optimization for the extraction and purification of extracellular vesicles (EVs) from cultured cells as well as from fresh breast cancer interstitium. Similarly, the system provides for lymph node remodeling by human breast cancer EVs in a humanized mouse model. Hydrogel particles are employed to convey cytokine releasing and EV-displaying treatment to afflicted bodies.

  • Publication number: 20190117156
    Abstract: A wearable device measures, tracks, and monitors a wearer's physical physiological conditions during a rehabilitation period. Metrics such as temperature, patellar shifting, limb circumference, and acceleration may be collected. Changes in monitored conditions may be assessed for detecting medical abnormalities which require specialized attention, including for example embolisms or infections. A networked communication system and various user interfaces may be used for medical support personnel and patients alike to stay updated with the patient's rehabilitation progress and to make adjustments in a patient's individual rehabilitation program.

  • Publication number: 20160320401
    Abstract: An assay device for determining the presence of analytes in a cell lysate comprises a porous support member and a plurality of binding reagents arranged and immobilized at multiple reaction sites on the support member. The binding reagents are selected and arranged to assess the status of a selected cellular signal transduction pathway/protein-protein interactive network. In a further aspect, a method for assessing the status of a signal transduction pathway comprises generating a lysate of cells, the lysate retaining one or more pathway molecules present in one or more states and the pathway molecules reflecting signal transduction events taking place in the cells. The method further includes applying the lysate to an immobilized series of binding reagents which can discriminate the pathway molecules and their states. Binding events between the pathway molecules and the binding reagents are identified and the state of the selected signal pathway is determined.

  • Patent number: 9383299
    Abstract: 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.

  • Patent number: 9096833
    Abstract: 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.

  • Patent number: 9086414
    Abstract: The present invention provides reliable methods to identify subsets of subjects with a cancer of epithelial origin characterized by a high level of phosphorylated c-erbB2 which does not correlate with the over-expression of total c-erbB2 as measured by IHC or FISH, for selection and inclusion for c-erbB2-direct treatment and therapy. Furthermore, the present invention provides a reliable method to determine whether a subject with a cancer of epithelial origin who has been determined to be c-erbB2 positive by IHC and by FISH should be excluded from c-erbB2-direct treatment because of a non-significant level of phosphorylated c-erbB2 in epithelial tumor tissue.

  • Patent number: 9029076
    Abstract: This invention relates, e.g., to a composition that, at room temperature, when contacted with a sample comprising phosphoproteins, can fix and stabilize cellular phosphoproteins, preserve cellular morphology, and allow the sample to be frozen to generate a cryostat frozen section suitable for molecular analysis. The composition comprises (1) a fixative that stabilizes the proteins in the sample and that has a sufficient water content for a stabilizer and/or a permeability enhancing agent to be soluble therein; (2) a stabilizer, comprising (a) a kinase inhibitor and (b) a phosphatase inhibitor and, optionally, (c) a protease (e.g., proteinase) inhibitor; (3) a permeability enhancing agent; and (4) lactic acid. Methods and kits are described for preserving phosphoproteins, using such a composition. Also described are endogenous surrogate markers for monitoring protein degradation, including the loss of posttranslational modifications (such as phosphorylation), e.g.

  • Patent number: 9012240
    Abstract: An immunoassay device incorporating porous polymeric capture nanoparticles within either the sample collection vessel or pre-impregnated into a porous substratum within fluid flow path of the analytical device is presented. This incorporation of capture particles within the immunoassay device improves sensitivity while removing the requirement for pre-processing of samples prior to loading the immunoassay device. A preferred embodiment is coreshell bait containing capture nanoparticles which perform three functions in one step, in solution: a) molecular size sieving, b) target analyte sequestration and concentration, and c) protection from degradation. The polymeric matrix of the capture particles may be 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.
