  • Publication number: 20190344277
    Abstract: A microfluidic detection system for micrometer-sized entities, such as biological cells, includes a detector component incorporating a plate with a plurality of opening, the plate separating two chambers, one in communication with a fluid source containing target cells bound to magnetic beads. The openings are sized to always permit passage of the magnetic beads therethrough into a lower one of the chambers and are further sized to always prevent passage of the target cells from the upper one of the chambers. The detector component further includes a magnet positioned to pull unbound magnetic beads through the openings and to capture target cells bound to magnetic beads on the surface of the plate. The microfluidic detection system includes a pump flowing the fluid through the detector component at high flow rates of milliliters per minute for high throughput detection of target cells.

  • Publication number: 20190160172
    Abstract: Aspects of the present disclosure generally relate to compounds for targeting and healing bone fractures. Some of these compounds include a negatively charged oligopeptide comprising an acidic oligopeptide, a linker, which may be hydrolyzable or may be a substrate for the protease cathepsin K, and at least one molecule that promotes bone healing. In some compounds the molecule that promotes bone healing is an anabolic compound that inhibits GSK3?, in some compounds the molecule that promotes the healing of bone fracture is a pro-inflammatory agent such as PGE1. Other embodiments include methods of treating a bone fracture comprising administering a therapeutic amount of any one of the compounds disclosed herein.
