Abstract: A method and system for a new form of computer-implemented social network. Existing social networks limit users interactions to the context provided by social networking clients, and also limit discussions of content to short clips with links back to the original website. The presented method and system enable users to interact with each other within the context of a third-party web page. Users can mark up a third-party web page to leave each other notes, chat, or highlight text, all without requiring any modification to the server-side source code of the third-party web page.

Abstract: Disclosed is a urological device comprising a polymeric prosthesis coated on its surface by a grafted or interpenetrated hydrogel copolymer comprising 2-hydroxyethyl methacrylate, methacrylic acid, and a crosslinking agent, wherein each constituent of said copolymer is present in an amount selected from a defined range of mole fraction %. The hydrogel exhibits a shrink/swell behavior which varies with changing urine composition such that the polymer undergoes swelling and collapse in rapid response to said change and thereby prevents calcium encrustation. Also disclosed is a method for making the device.
