Abstract: The present invention provides methods for identification of subjects with a rise in plasma coagulability post-diagnosis of thrombotic event (and consequent increased risk for recurrent thromboembolism) as well as for identification of subjects without thrombotic event who exhibit a rise in plasma coagulability for which prophylactic anticoagulation may be warranted for TE prevention, and other methods for identification of perioperative subjects who are at heightened risk for perioperative bleeding and/or for requiring blood transfusion, using the CloFAL assay, to aid in clinical decision making regarding anticoagulant and/or adjunctive clinical management designed to mitigate this heightened thromboembolic risk.
Abstract: A wearable sensor system includes a flexible patch, an electronic circuit disposed on the flexible patch, and a disposable sensor disposed on the flexible patch and connected to the electronic circuit via a socket. The disposable sensor detects a chemical compound. The electronic circuit generates a detection signal commensurate with the chemical compound detected by the disposable sensor. The disposable sensor is removably plugged into the socket, thereby permitting replacement of the disposable sensor upon satisfaction of a predetermined condition. A battery disposed is on the flexible patch and connected to the electronic circuit to power the electronic circuit. A transceiver is connected to the electronic circuit, wherein the transceiver transmits the detection signal.

Abstract: An antenna includes a waveguide defined by a gap between a backplane with radial support ribs and a facesheet, a teardrop-shaped feed pin at a center of the backplane, and a foam spacer between the backplane and facesheet. An outward facing side of the facesheet includes thermal paint. The facesheet includes pairs of through-hole slots for releasing portions of a wave of radiation in the waveguide to generate a transmit-beam or to receive the receive-beam to generate the wave of radiation. The pairs may be disposed as a spiral array about a center of the facesheet. Each of the pairs may include first and second slots. A length of the second slot is oriented approximately perpendicular to a length of the first slot. Dispositions of the slots are set by a computer process. The dispositions optimize a trade-off between transmit and receive gains.
Abstract: The presently disclosed subject matter provides a scalable and electrostretching approach for generating hydrogel microfibers exhibiting uniaxial alignment from aqueous polymer solutions. Such hydrogel microfibers can be generated from a variety of water-soluble natural polymers or synthetic polymers. The hydrogel microfibers can be used for controlled release of bioactive agents. The internal uniaxial alignment exhibited by the presently disclosed hydrogel fibers provides improved mechanical properties to hydrogel microfibers, and contact guidance cues and induces alignment for cells seeded on or within the hydrogel microfibers.

Abstract: The instant disclosure provides methods and compositions for the diagnosis, treatment and prevention of a TGF?2-associated disease, disorder and/or condition, including, e.g., Scleroderma, other fibrotic disease, grade 4 glioblastoma (GBM) and/or Primary Open-Angle Glaucoma (POAG).

Abstract: The identification of mutations that are present in a small fraction of DNA templates is essential for progress in several areas of biomedical research. Though massively parallel sequencing instruments are in principle well-suited to this task, the error rates in such instruments are generally too high to allow confident identification of rare variants. We here describe an approach that can substantially increase the sensitivity of massively parallel sequencing instruments for this purpose. One example of this approach, called “Safe-SeqS” for (Safe-Sequencing System) includes (i) assignment of a unique identifier (UID) to each template molecule; (ii) amplification of each uniquely tagged template molecule to create UID-families; and (iii) redundant sequencing of the amplification products. PCR fragments with the same UID are truly mutant (“super-mutants”) if ?95% of them contain the identical mutation.

Abstract: Described herein are methods comprising administering to a mammalian subject an effective amount of an annexin chimeric fusion protein, wherein the annexin chimeric fusion protein comprises at least one immunogenic antigen, thereby enhancing the antigen specific immune response relative to administration of the immunogenic antigen alone. Methods and kits for treating or preventing recurrence of hyper proliferating diseases, e.g., cancer, are described. A method may comprise priming a mammal by administering to the mammal an effective amount of a chemotherapeutic agent and boosting the mammal by administering to the mammal an effective amount of an annexin chimeric fusion.

Abstract: A device may obtain field images of a tissue sample, apply, to the field images, spatial distortion and illumination-based corrections (including corrections for photobleaching of reagents) to derive processed field images, identify, in each processed field image, a primary area including data useful for cell or subcellular component characterization, identify, in the processed field images, areas that overlap with one another, and derive information regarding a spatial mapping of cell(s) and/or sub-cellular components of the tissue sample. Deriving the information may include performing segmentation based on the data included in the primary area of each processed field image, and obtaining flux measurements based on other data included in the overlapping areas.
Abstract: Blockade of immune checkpoints such as cytotoxic T-lymphocyte antigen-4 (CTLA-4) and programmed death-1 (PD-1) shows promise in patients with cancer. Inhibitory antibodies directed at these receptors have been shown to break immune tolerance and promote anti-tumor immunity. These agents work particularly well in patients with a certain category of tumor. Such tumors may be particularly susceptible to treatment because of the multitude of neoantigens which they produce.
