International Classification:

G01N 3353

US Classification:

435 71, 4241401, 4242331, 4241311, 4241591, 4242781, 424 931, 530351, 514885

Abstract:

Methods of reducing pre-existing humoral immunity to a viral immunogenic therapeutic agent such as adenovirus, using immunoapheresis are disclosed. Antibodies specific for the viral immunogenic therapeutic agent are selectively removed from the blood of an individual prior to administration of the viral immunogenic therapeutic agent by reaction extracorporeally with an immunosorbent which specifically binds the antibody. After the antibody is selectively removed from the blood, the blood is reinfused into the patient and the viral immunogenic therapeutic agent is administered. The invention also provides kits and compositions for selective removal of anti-viral antibody.

US Classification:

424 932, 435455, 435456, 4353201

Abstract:

The invention provides methods of treating neoplasia using combinations of target cell-specific replication competent adenoviral vectors and chemotherapy, radiation therapy or combinations thereof. The adenoviral vectors are target cell-specific for the particular type of neoplasia for which treatment is necessary and the combination with the chemotherapy and/or radiation leads to synergistic treatment over existing adenoviral therapy or traditional chemotherapy and radiation therapy.

International Classification:

A61B 17/00

US Classification:

606204

Abstract:

A method and device for the treatment of anxiety disorder, including panic attacks. A hammer is used to tap the cutaneous region of the bladder channel on the back until the skin turns pink. The skin on the abdomen, arms, legs, and buttocks can also be used for treatment. The hammer preferably has a magnetic piece in one end of the hammer head. The method can treat anxiety disorder including panic attack, general anxiety, phobia, posttraumatic stress disorder, stress related tension headache, insomnia, and any stress. Patients can use the hammer to treat themselves at home, office, and during traveling. The method and device are simple, effective, nontoxic, safe, have no side effects, inexpensive, and convenient.

US Classification:

713175, 713153, 713168

Abstract:

A method for securing a communication between a peer node and an intermediary peer node in a peer-to-peer network comprises the peer node generating a secured communication request to the intermediary peer node. The intermediary peer node authenticates the peer node in response to the secured communication request. The intermediary peer node issues a signed certificate of authority upon successful authentication.

US Classification:

438674, 438622, 438637, 257E21273

Abstract:

Metal ink compositions, methods of forming such compositions, and methods of forming conductive layers are disclosed. The ink composition includes a bulk metal, a transition metal source, and an organic solvent. The transition metal source may be a transition metal capable of forming a silicide, in an amount providing from 0. 01 to 50 at. % of the transition metal relative to the bulk metal. Conductive structures may be made using such ink compositions by forming a silicon-containing layer on a substrate, printing a metal ink composition on the silicon-containing layer, and curing the composition. The metal inks of the present invention have high conductivity and form low resistivity contacts with silicon, and reduce the number of inks and printing steps needed to fabricate integrated circuits.

US Classification:

707769, 707770

Abstract:

Methods and apparatus, including computer program products, implementing and using techniques for performing a partial update of a hierarchically structured document referencing one or more records stored in a database. An expression specifying one or more updates to be applied to the document is received. The document is searched to find update target position(s). Based on the received expression, a pending update list is built. When an update target position is found, a row of a document column in a base table is updated with the new version number for the document. New database records for insertion into the new document version are generated from the pending update list. Old database records to be replaced are identified. A database table for the document is updated to mark the old database records as obsolete and to add new database records to be referenced in the new version of the document.
