20080233081 | PRO-ANGIOGENIC PEPTIDES - This present invention generally relates to peptides, compositions, treatment methods, and devices useful for the medical diagnosis and treatment of pathogenic disorders. More specifically, the invention relates to immunostimulatory peptides which can stimulate the production of therapeutically beneficial cytokines. The peptides of the invention can regulate the release of a specific pattern of cytokines that promote angiogenesis, and modulate the immune system of a subject, without inducing deleterious side effects such as inflammation. Therefore, the peptides have therapeutic importance, particularly with respect to wound healing and restoration of circulation to damaged tissues. | 09-25-2008 |
20080292650 | THERAPEUTIC AND DIAGNOSTIC PEPTIDES - This invention generally relates to peptides useful for medical diagnosis and treatment of pathogenic disorders. More specifically, the invention relates to immunostimulatory peptides which can stimulate the production of therapeutically beneficial cytokines and, in combination with antibodies against human pathogens such as the immunodeficiency virus (HIV), inhibit replication of such pathogens. The peptides interact synergistically with pathogen-directed antibodies without producing or sustaining serious side-effects such as inflammation, and provide the potential for treatment modalities that are non-specific with respect to pathogen and cell type. Therefore, the peptides of the present invention have wide applicability with respect to medical treatment of pathogen-mediated infections, and the potential to enhance well-being. | 11-27-2008 |
20100285003 | THERAPEUTIC PEPTIDES AND USES THEREOF - The present invention is directed to a family of therapeutic peptides capable of modulating cytokine expression and/or stimulating the immune system of subject without producing or sustaining serious side-effects. Methods using the peptides to modulate cytokine expression in a subject, treat a disease, enhance vaccination, and stimulate a subject's immune system response are also disclosed. | 11-11-2010 |
20100286040 | PRO-ANGIOGENIC PEPTIDES AND USES THEREOF - This present invention is directed to peptides, compositions, and methods for modulating endogenous cytokine expression in a subject. More specifically, the invention provides peptides useful in regulating the release of a specific pattern of cytokines that promote angiogenesis and/or can be used to modulate the immune system of a subject. | 11-11-2010 |
20140155313 | HYDROGELS WITH COVALENTLY LINKED POLYPEPTIDES - The present invention provides methods of synthesizing hydrogels that contain covalently linked polypeptides. These polypeptides may be tetravalent peptides or polypeptides that bind to cell surface receptors. The hydrogels synthesized by the methods of the present invention may be used in wound dressings or applied directly to wounds to promote healing. | 06-05-2014 |

20110297366 | JUMPER - A jumper for insuring electrical or fluid communication between the liner and the casing of an oil field downhole. The jumper has a first tubing adapted to be inserted in the liner, a second tubing adapted to be inserted in the casing and an anchor adapted to be rigidly mounted in the casing. The first and second tubings are composed of an electrically conductive material and are supported by the anchor with an insulated joint. Each of the first and second tubings has a plurality of centering devices, each consisting of a pair of rings surrounding the tubing and an array of bowed springs bridging between the rings and biased to bow outwardly from the tubing into engagement with the inner circumference liner or the casing, as the case may be. One of the two rings is electrically connected to the tubing, for example by welding, whereas the other ring is free to be displaced longitudinally of the tubing so that the outer diameter of the array of bowed springs may expand or contract, as needed. Each bowed spring in the array is provided with a series of electrical contacts which insure electrical conductivity between the welded ring and the surrounding liner or casing through the bowed spring. | 12-08-2011 |
20120112753 | ELECTRODE - An electrode for enhancing electrical conductivity between an oil or gas field downhole and the surrounding formation. The electrode may serve as a cathode to cooperate with a remote anode to produce an electric field through the formation. The electrode has an electrically conductive, elongated body with a proximal end adapted to be inserted into the production pipe and a distal end adapted to project into the formation. The body of the electrode has a series of radially-projecting flexible filaments. The filaments are composed of an electrically conductive material and are supported by the body so as to be electrically charged. At least one of the filaments project outwardly into engagement with the wall of the downhole. The filaments also project radially outward into the consolidated formation. | 05-10-2012 |
20130277046 | METHOD FOR ENHANCED OIL RECOVERY FROM CARBONATE RESERVOIRS - Method of using direct current (DC) electrokinetics to enhance oil production from carbonate reservoirs The method comprising the steps of selecting an underground formation comprising an Oil-bearing carbonate reservoir, positioning two or more electrically conductive elements at spaced apart locations in proximity to said formation, at least one of said conductive elements being disposed in or adjacent to a bore hole affording fluid communication between the interior of said bore hole and said formation, passing a controlled amount of electric current along an electrically conductive path through said formation, said electric current being produced by a DC source including a cathode connected to one of said conductive elements and an anode connected to another of said conductive elements, said electrically conductive path comprising at least one of connate formation water and an aqueous electrolyte introduced into said formation, and withdrawing oil from at least one of said bore holes. | 10-24-2013 |
