Inventor: BASKA KANAG
IPC: A61M16/00
Filed: 2008-08-27
Abstract: A device for maintaining an airway in a patient comprises mask having a peripheral portion that forms a seal with the larynx when the mask is positioned in the laryngo pharynx to thereby prevent ingress of extraneous fluids into the larynx and n airway tube connected to or formed with the mask for passing gas to the larynx when the mask is properly inserted into the laryngo pharynx. The peripheral portion of the mask includes a soft, flexible portion that contacts tissues surrounding the laryngeal opening when the device is inserted into a patient, the soft, flexible portion being arranged whereby application of pressurised gas to the airway tube urges the soft, flexible portion into contact with the tissues surrounding the laryngeal opening or the pharyngeal wall.

Abstract: The invention relates to imidazopyridinones, to their use in medicine, to compositions containing them, to processes for their preparation and to intermediates used in such processes. By activating TLRs, it should be possible to induce or stimulate immune cells to mount an immune response. In particular, the TLR7 has been implicated in viral infections (such as HCV or HBV), cancers and tumours, and T2 Helper cell (TH2) mediated diseases, and hence TLR7 agonists are potentially useful in the treatment of such diseases. We have now found a series of imidazopyridinones which are agonists of TLR7. According, there is provided a compound of formula (1) or a pharmaceutically acceptable salt or solvate thereof, wherein R1 is 3- to 8-membered saturated heterocyclic group wherein one ring member is -O-; and R2 is phenyl or pyridinyl, each optionally substituted by C1-C6alkyl.

Abstract: Latex spray foams formed from a two-part foamable composition are provided.  The A-side contains a functionalized latex and an acid and the B-side contains a polyfunctional aziridine crosslinking agent, a plasticizer, a base, and, optionally, a non-functionalized resin. The acid and the base form a blowing agent package that when mixed, react to form a gas. The A- and B-side also contain thickening agents. The polyfunctional aziridine crosslinking agent is diluted by a plasticizer, which reduces the viscosity of the B-side and reduces the amount of ethyleneimine, a toxic component in the polyfunctional aziridine crosslinking agent. The presence of a plasticizer also permits the inclusion of other materials that may add functionality and/or cost savings to the foamed product. The plasticizer should have no acidic protons to react with the crosslinking agent. When no acidic protons are present, the B-side is stable for extended periods of time.
