  • POLYMERIC NANOPARTICLES USEFUL IN THERANOSTICS
    Publication number: 20190233567
    Abstract: Synthesis and characterization of starch based pH-responsive nanoparticles for controlled drug delivery are described. Polymethacrylic acid grafted starch (PMAA-g-St) nanoparticles with various molar ratio of starch to MAA were synthesized by a new one-pot method that enabled simultaneous grafting of PMAA and nanoparticle formation in an aqueous medium. NMR data showed that polysorbate 80 was polymerized into the graft polymer. Nanoparticles were relatively spherical with narrow size distribution and porous surface morphology and exhibited pH-dependent swelling in physiological pH range. The particle size and magnitude of volume phase transition were dependent on PMAA content and formulation parameters such as surfactant levels, cross-linker amount, and total monomer concentration. The results showed that the new pH-responsive nanoparticles possessed useful properties for controlled drug delivery.

  • Parallel input/output via multipath software
    Patent number: 10268517
    Abstract: A batch of input/output (I/O) requests, directed to multiple physical domains of storage area network disk (SAN disk), are prioritized for processing based on the workload (pressure) of the target physical domains, and further based on the workload of multiple input/output (I/O) paths available for transmission of the I/O data to or from the physical domains. Requests directed to a physical domain with low pressure (relative to other physical domains to which some of the I/O requests are directed) are queued up and sent to the physical domain on an I/O path having a low workload (relative to other available I/O paths). Requests directed to a physical domain under relatively high pressure are queued up and sent to the physical domain on an I/O path having a relatively higher workload.
