Patent CA-2493453-A1 (CA)
Title: Oral pharmaceutical formulation in the form of a plurality of microcapsules for prolonged release of active principle(s) with low solubility
Inventor: GUIMBERTEAU FLORENCE
IPC: A61K9/50
Filed: 2003-07-28
Abstract: The invention concerns microcapsules with prolonged release of active principles with low solubility, consisting of a core containing the active principle and coated with a polymer layer which controls the release of the active principle. The aim is that said oral microcapsules containing hardly soluble active principles, should have a coating film of sufficient thickness to ensure controlled permeability and should be adapted to industrial reproduction. This is achieved by the inventive microcapsules of mean diameter less than 1000 microns, and whereof the coating film contains a film-forming polymer (P1) insoluble in gastrointestinal tract fluids, a water-soluble polymer (P2), a plasticizer (PL), and optionally a lubricating surfactant (TA). Said microcapsules are characterized in that their coating films represents at least 3 % p/p of dry matter, relative to their total weight and their core contains a hardly soluble active principle and a solubilizing agent (polyoxyethylene hydrogenated castor oil) which provides the core wherein it is contained with properties such that the behaviour of the exposed core (non-coated) in a given dissolving test (TD), is as follows: release of 80 % of active principle in less than two hours. The invention also concerns the use of such microcapsules in galenic formulation.

Title: Resolvins: biotemplates for novel therapeutic interventions
Inventor: SERHAN CHARLES N
IPC: C07F7/18
Filed: 2003-08-12
Abstract: The present invention is generally drawn to novel isolated therapeutic agent s, termed resolvins, generated from the interaction between a dietary omega-3 polyunsaturated fatty acid (PUFA) such as eicosapentaenoic acid (EPA) or docosahexaenoic acid (DHA), cyclooxygenase-II (COX-2) and an analgesic, such as aspirin (ASA). Surprisingly, careful isolation of compounds generated fro m the combination of components in an appropriate environment provide di- and tri-hydroxy EPA or DHA compounds having unique structural and physiological properties. The present invention therefore provides for many new useful therapeutic di- or tri-hydroxy derivatives of EPA or DHA (resolvins) that diminish, prevent, or eliminate inflammation or PMN migration, for example. The present invention also provides methods of use, methods of preparation, and packaged pharmaceuticals for use as medicaments for the compounds disclosed throughout the specification.

Title: High-speed silicon-based electro-optic modulator
Inventor: MONTGOMERY ROBERT KEITH
IPC: G02F1/225
Filed: 2004-03-23
Abstract: A silicon-based electro-optic modulator (30) is based on forming a gate region of a first conductivity to partially overly a body region of a second conductivity type, with a relatively thin dielectric layer (10) interposed between the contiguous portions of the gate and body regions (12, 10). The modulator may be formed on an SOI platform, with the body region formed in the relatively thin silicon surface layer of the SOI structure and the gate region formed of a relatively thin silicon layer (10) overlying the SOI structure.  The doping in the gate and body regions is controlled to form lightly doped regions above and below the dielectric, thus defining the active region (16) of the device. Advantageously, the optical electric field essentially coincides with the free carrier concentration area in this active device region. The application of a modulation signal thus causes the simultaneous accumulation, depletion or inversion of free carriers on both sides of the dielectric at the same time, resulting in high speed operation.
