20110059916 | Methods and Compositions for Inducing Torpor in a Subject - The present invention relates to the discovery the 5′-AMP and analogues thereof can be used to induce a state of torpor or suspended animation in subjects, as exemplified by studies carried out in laboratory mice. In these studies; mice were injected with high doses of 5′-AMP, which was found to result in a decoupling of the animals' body temperature regulation mechanism accompanied by a reduction in the animals' core body temperature, which tended to lower towards the ambient environmental temperature. It was further discovered that the introduction of high levels of 5′-AMP resulted in an induction of fat regulation genes such as procolipase (Clps) in tissues and organs that do not normally express Clps, this in turn was accompanied by a shift in metabolism from a primarily glycolytic energy metabolism (which is inhibited at lower temperatures) to one that relied primarily on the liberation and metabolism of free fatty acids. Substantial medical and other applications that arise out of this discovery are also disclosed. | 03-10-2011 |

20100255311 | Metal Nanoparticles functionalized with rationally designed coatings and uses thereof - The present invention provides a composition and method for functionalizing nanoparticles that enables them to undergo reversible aggregation/deaggregation. The aggregation properties of this new system are reversible and readily monitored by optical absorbance measurements with the possibility of electrical and/or magnetic monitoring as well. The outer portion of the coating material is functionalized with polyethylene glycol (PEG) entities that facilitate biocompatibility and stability both in solution and in the solid state. Also provided are nanoparticles functionalized with rationally designed free radical initiators to effect tailored polymer growth from the surface. These systems may be used for a broad variety of applications, including biosensing with real-time feedback. | 10-07-2010 |

20130104035 | GPS TRACKING SYSTEM AND METHOD EMPLOYING PUBLIC PORTAL PUBLISHING LOCATION DATA - A GPS tracking device sends multiple real-time location coordinates to a database which is then published on a secured webpage containing a map and device location. The GPS tracking device owner can retrieve the publishing code or URL from the secured webpage and can then publish the portal in any public internet media outlet such as websites, internet 1Vs and mobile devices. With this method, the owner can share the real-time location of the GPS devices to the user being shared without security verification or software installation on the user's computer or mobile device. To share the location of the GPS tracking device, the owner needs only to embed a set of publishing codes on a webpage or share a web URL. This method is beneficial for anyone wanting to share real-time physical location. The user can access the shared location by viewing the published public portal without security verification. | 04-25-2013 |
