Title: Enhanced wireless packet data communication system, method, and apparatus applicable to both wide area networks and local area networks
Inventor: BOUDREAUX GORDON J
IPC: H04L5/12
Filed: 2002-03-29
Abstract: A cellular wireless packet data communication system containing transmit-only endpoint devices (HA40, HA50) which transmit to receive-only base stations (B1, B2, BN). The system is configured to allow for large area coverage (e.g., a metropolitan area) with far fewer number base stations than are required with conventional two-way cellular systems. The base station coverage areas are configured to overlap, allowing for reception of packets at multiple base stations. A data concentrator (HA60) resolves redundantly received messages.  The network is configurable as a WAN, a LAN, or a combination of the two.  Novel modulation techniques (e.g., a 16QAM submodulation together with a 7FSK  modulation) are used such that low cost components can be used in the transmitters and receivers while achieving outstanding probability of success performance. The endpoint devices are battery operated and accordingly, are designed for low power consumption and multi-year battery life. The system is used in a variety of applications including remote monitoring and mobile communications.

Title: Compositions and methods for inhibiting metastasis
Inventor: PIZZO SALVATORE V
IPC: A61K48/00
Filed: 2002-05-22
Abstract: Compounds, compositions and methods for inhibiting metastasis and screening methods for identifying compounds are disclosed. The compounds bind to CD26 and/or plasminogen, and when so bound, inhibit the Ca+2 signaling cascade th at results in the formation of MMP-9. When the compounds directly bind to CD26 in a manner that inhibits the signaling cascade, they inhibit metastasis. When the compounds enhance the ability of angiostatin to bind to CD26 and inhibit the signaling cascade, they are angiostatin allosteric promoters. The compounds can also bind to CD26 in a manner which inhibits the binding of AD A to CD26/DPP IV, and such compounds used in methods for inhibiting deaminatio n of adenosine. The compounds can be, for example, antibodies, antibody fragments, enzymes, peptides, nucleic acids such as oligonucleotides, or sma ll molecules. The antibodies can be monoclonal, humanized, or polyclonal antibodies. The compounds can be conjugated to or combined with various cytotoxic agents and/or labeled compounds. Methods for inhibiting tumor metastasis can be used to treat patients suffering from such tumors.

Filed: 2002-11-01
Abstract: Novel genes encoding homologous immunoreactive thio-disulfide oxidoreductases, or disulfide bond formation (Dsb) proteins fromEhrlichia chaffeensis and Ehrlichia canis are disclosed. While the E. chaffeensis and E. canis Dsb proteins are at most only 31 % or less homologous to other known Dsb proteins, the Ehrlichia Dsbs contain a cysteine active site, Cys-Cly-Tyr-Cys, similar to those in known Dsb proteins. As predicted by 15-amino acid identical N-terminal signal peptides, the proteins are primarily localized in the periplasm of E. chaffeensis and E. canis, possibly playing a role in antigenicity and pathogenesis. The present invention provides the nucleotide and amino acid sequences and expression vectors for the E. chaffeensis and E.canis genes, antisera directed against the proteins, and kits to determine whether an individual or animal is infected with a given species of Ehrlichia.
