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.

An apparatus and method for hermetically sealing, EMI shielding integrated circuits for high-speed electronic devices using a combination of microstrip to buried stripline interface for signal transmission from the integrated circuit. The packaging provided comprises a first plurality of microstrips interconnecting the integrated circuit to a plurality of buried striplines exposed on a surface of the main substrate. A ceramic interposer placed over the main substrate âburiesâ a portion of the exposed striplines on the main substrate to thereby insulate these signal paths from a hermetically sealing, and EMI shielding metal lid placed over the integrated circuit. The metal lid and the seal ring brazed over the ceramic interposer thus provide both a hermetic seal and an electric radiation block. A reduction in dispersion due to the buried striplines is also achieved, as well as improving jitter performance.

An integrated high-speed package comprising a package housing having a housing lip and connector having a center pin abutting along a bottom surface of the housing lip. For signal registration of a first substrate to the signal lead, the substrate is âfloatedâ up to the housing lip, which provides an alignment reference to ensure that the top surface of the first substrate is aligned and in direct registration with the signal lead. In another embodiment, the center pin to substrate registration is provided at a top surface of a housing base. The housing base preferably comprises a first portion of a first height and a second portion of a second height. Accordingly, the housing base can accommodate substrates of different thickness while allowing a top surface of the first and a second substrate to be coplanar to facilitate signal registration there between.

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.

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.

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.
