20130089592 | METHOD OF PRODUCING A HYDROGEL - The invention provides a method of enzymatically modifying xylan by selectively removing glucuronic acid and/or arabinose side chains from the xylan with a-D-glucuronidase and/or a-L-arabinofuranosidase, and allowing the modified xylan to form into a hydrogel when the xylan becomes insoluble. A bioactive substance, such as a protein, enzyme, antimicrobial agent, bactericide or pharmaceutical compound can be added to the xylan so that the substance is encapsulated within the hydrogel or incorporated onto its surface. The hydrogel can be used as a drug delivery agent, such as for sustained-release or targeted drug delivery, rectal drug delivery or a dressing for a wound, burn or scar. The hydrogel can also be used as a coating, such as on medical gloves, catheters, surgical drainage systems, utensils or the like, or can be used in a scaffold for tissue engineering. | 04-11-2013 |
20130233501 | MODIFICATION OF XYLAN - The invention provides a method of modifying soluble xylan which contains glucuronic acid and/or arabinose side chains so that it can be adsorbed onto other substrates. The method includes the steps of enzymatically modifying the xylan by selectively removing glucuronic acid and/or arabinose side chains from the xylan with α-D-glucuronidase and/or α-L-arabinofuranosidase, and allowing the modified xylan to adsorb onto the substrate. The substrate may be a cellulosic substrate like pulp or paper or a non-cellulosic substrate. The enzymes are able to remove a sufficient number of the xylan side chains so as to decrease water solubility of the xylan, induce xylan precipitation and allow adsorption of the xylan onto other substrates. A pulping process which incorporates modification of xylan and adsorption onto cellulosic material is also provided, as are products which contain the modified xylan. | 09-12-2013 |

20120233351 | Method of directing network traffic - A method of directing network traffic wherein a router IP address is registered and associated with at least one website address. At a user device, a domain name request is made via that router. This request is directed to a virtual network server configured to ascertain the registered website address associated with the router IP address. The user device is then automatically redirected to request the registered website address. The user device is then served one or more web pages associated with that website address. | 09-13-2012 |
20120330930 | System for multiple database correlation of location based information - A method includes loading an application on a user device wherein the application is configured to receive information requests and to launch search requests utilizing a web mapping service with a local search feature. After launching a search request via the application, the user device receives search results from the web mapping service. At the application, the results are analyzed to ascertain if a search result corresponds to an information request. Such data is added, when not already present, to the database. | 12-27-2012 |

20130023289 | Location Based Service and System - A location based service and system wherein a database includes customer records each mapped to customer location information. A user device launches a request to the server. The request includes user device location data, from the user device location data, a geopositional frame about the user location is calculated and used to search customer location information in the database and to retrieve customer records within the geopositional frame corresponding to the launched request. | 01-24-2013 |
