US Classification:

424493, 536 54, 536115, 536118, 536124, 514 54, 424489

Abstract:

The present invention relates to microspheres comprising hyaluronan derivatized with a bifunctional crosslinker to form microspheres. Methods of making such microspheres, comprising mixing hyaluronic acid and a dihydrazide with a crosslinker in an aqueous solution, adding a solvent and an emulsifying agent to form an emulsion, and lowering the pH of the emulsion to allow intramolecular and intermolecular crosslinking to occur, are also disclosed. The invention also provides for pharmaceutical or cosmetic formulations based on the microspheres described herein, further containing one or more active or cosmetic agents, and methods of using such formulations.

US Classification:

375261000, 375260000

Abstract:

A multi-dimensional Burst Link Access Streaming Transmission (BLAST) architecture, which provides flexible physical apparatus for balanced performance of data throughput, latency, and reliability of transmission (e.g. graceful degradation). A schedule is sent from a master node to alert targeted nodes regarding messages to be sent. The master node uses a P-Band transmission link operating a regular intervals to synchronize the system in preparation for receipt of a message over a synchronous link. Each node has the capability of sending and receiving synchronous and asynchronous messages.
