Patent CA-2270286-A1 (CA)
Title: Therapeutic use of an agent that stimulates no or prostacyclin production and delivery device
Inventor: YLAE-HERTTUALA SEPPO
IPC: A61K9/00
Filed: 1997-11-03
Abstract: Vascular endothelial growth factor (VEGF) has utility in the treatment of intimal hyperplasia, hypertension and atherosclerosis, and of conditions susceptible to treatment with agents that produce nitric oxide or prostacyclin. Instead of VEGF, an equivalent agent such as an agonist of VEGF receptors may be given, as may nucleic acid encoding such an agonist. The agent may successfully be administered via the adventitial surface of a blood vessel, e.g. using a device which defines a reservoir between the body wall and the vessel's adventitial surface, the reservoir being at least part-filled by a pharmaceutical formulation containing the agent to be delivered.

Patent CA-2271805-A1 (CA)
Title: Method and device for connecting components
Inventor: FABER THOMAS
IPC: B23K20/16
Filed: 1997-11-11
Abstract: The invention concerns the connecting of components by friction welding, in particular for connecting pipes in situ when sinking well drill holes and/or completing bores, for example underground bores. The amounts of heat necessary for the welding process are generated by a friction element in a manner known per se, and the ends of the components to be connected are joined in an upsetting process when a weldable plasticized state has been attained. According to the invention, the friction element is a simple friction disc whose material is completely used up during the friction process in the region of the friction surfaces until the components to be connected contact each other. The resultant friction and upsetting burr is removed by utilizing the rotational energy of the friction element. Whilst reducing the level of complexity in terms of plant required, the invention permits the use of friction elements which do not have to be adapted to the exact dimensions of the components to be connected. The connection point has a simple weld seam which essentially consists of the basic materials of the components to be connected.

Title: Memory for information search through prefix analysis, in particular for building routing tables for nodes of high speed communication networks, such as the internet network
Inventor: INNOCENTI VIVIANA
IPC: H04L45/74
Filed: 1999-10-21
Abstract: A memory for searching information through prefix analysis, in particular for building routing tables for nodes of high speed communication networks, such as Internet network, comprises a memory element (M1 ) which stores a set of information items associated each one to a mask information indicative of the number of significant characters in the respective prefix and to a target information. For the implementation of a search criterion based on the longest prefix match, each cell comprises an information field that provides either an address of a next row for the continuation of a search or an information relating to a target reached, and a pair of flags (GO, TARGET) specifying the contents of the information field. An auxiliary vector (AUX), which comprises as many cells as many the memory rows are, is arranged to store, when the flags in a cell in the memory element indicate the reaching of a target together with the need of prosecuting search operations in a next row, the target information in its cell associated to said next row. (Fig. 1).

Title: Fusion proteins comprising a dimerization, trimerization or tetramerization domain and an additional heterologous transcription activation, transcription repression, dna binding or ligand binding domain
Inventor: GILMAN MICHAEL Z
IPC: A61K48/00
Filed: 1998-08-26
Abstract: The present invention relates to novel fusion proteins which activate transcription, to nucleic acid constructs encoding the proteins and their use in the genetic engineering of cells. Key fusion proteins of the invention contain at least two mutually heterologous domains, one of which being a bundling domain. Bundling domains include any domain that induces proteins that contain it to form multimers ("bundles") through protein-protein interactions with each other or with other proteins containing the bundling domain. Examples of bundling domains that can be used in the practice of this invention include domains such as the lac repressor tetramerization domain, the p53 tetramerization domain, a leucine zipper domain, and domains derived therefrom which retain observable bundling activity. Cells are engineered by the introduction of recombinant nucleic acids encoding the fusion proteins, and in some cases with additional nucleic acid constructs, to render them capable of ligand-dependent regulation of transcription of a target gene.  Administration of the ligand to the cells then regulates (positively, or in some cases, negatively) target gene transcription.
