Patent CA-2502225-A1 (CA)
Inventor: CULLY EDWARD H
IPC: A61M29/00
Filed: 2003-10-16
Abstract: An improved embolic filter frame (31) has looped support struts (34). The frame provides enhanced longitudinal compliance, improved sealing against a vessel wall and a short deployed length. The struts (34) have a high degree of radial stiffness with a low degree of longitudinal stiffness. The loop support struts elongate when tensioned and assume a compressed and essentially linear form. While constrained in this linear state by a delivery catheter (92), the support struts exert minimal stress onto the delivery system. The overall delivery profile and stiffness are therefore reduced. When the delivery catheter constraint is removed during deployment, the struts "snap open" and assume a looped configuration which exert a high degree of force onto the vessel wall, creating an enhanced filter to vessel wall seal. In addition, the looped struts (34) and the central collar (46) connecting the support struts to the support wire (36) are positioned essentially within the plane of the filter opening. The overall deployed length of the embolic filter (40) is reduced.

Inventor: KUNDU ANIRBAN
IPC: C12N9/88
Filed: 2003-12-15
Abstract: The invention relates to the discovery of a novel Chondroitinase Glycoproteins (CHASEGP's), methods of manufacture, and potential uses in conditions where removal of chondroitin sulfates may be of therapeutic benefit. Chondroitinase Glycoproteins require both a substantial portion of the catalytic domain of the CHASEGP polypeptide and asparagine-linked glycosylation for optimal chondroitinase activity. The invention also includes carboxy-terminal deletion variants of CHASEGP that result in secreted variants of the protein to facilitate manufacture of a recombinant CHASEGP. Further described are suitable formulations of a substantially purified recombinant CHASEGP  glycoprotein derived from a eukaryotic cell that generate the proper glycosylation required for its optimal activity. CHASEGP is useful for the degradation of glycosaminoglycans and chondroitin sulfate proteoglycans under clinical conditions where their removal is of therapeutic value.

Abstract: Methods and apparatus for processing registration requests by a Home Agent supporting Mobile IP are disclosed. A registration request is received from each of a plurality of Mobile Nodes, the registration request specifying a care-of address, which may be allocated by the Foreign Agent. A binding is established between each of the plurality of Mobile Nodes and the associated care-of address, each of the plurality of Mobile Nodes being associated with one another. For instance, the plurality of Mobile Nodes may be statically or dynamically assigned the same Home Address. A tunnel is then created between the Home Agent and the care-of address for each of the plurality of Mobile Nodes, thereby enabling a server request to be distributed by the Home Agent to one of the plurality of Mobile Nodes or to a cluster of Mobile Nodes (e.g., associated with the care-of address) via the associated tunnel. For instance, a server request addressed to the Home Address may be forwarded directly to one of the Mobile Nodes assigned that Home Address. Alternatively, when an address such as the care-of address is associated with multiple Mobile Nodes, the Foreign Agent may perform a second level of dispatching such that the server request is dispatched to one of the Mobile Nodes in the cluster.

Abstract: A method for labeling acyl carrier protein (ACP) fusion proteins with a wide variety of different labels is disclosed. The method relies on the transfer of a label from a coenzyme A type substrate to an ACP fusion protein using a holo-acyl carrier protein synthase (ACPS) or a homologue thereof. The method allows detecting and manipulating the fusion protein, both in vitro and in vivo, by attaching molecules to the fusion proteins that introduce a new physical or chemical property to the fusion protein. Examples of such labels are, among others, spectroscopic probes or reporter molecules, affinity tags, molecules generating reactive radicals, cross-linkers, ligands mediating protein-protein interactions or molecules suitable for the immobilization of the fusion protein.

Abstract: Human and mammalian skin undergoes a variety of changes associated with chronological aging. Various environmental factors, disease states and genetic disorders may accelerate both the appearance of aging skin and also the structural and functional changes associated with aging skin. Ultraviolet radiation from the sun is one of the classic known and well-defined means of accelerating or worsening the aging of the skin and this is frequently termed photoaging. Other environmental factors, such as oxidative stress, free radicals, environmental toxins such as ozone and cultural customs or habits such as tobacco smoking are other known probe accelerators in photo aging skin. A wide variety of other factors known and unknown contribute to accelerated or premature aging of the skin. This invention discusses methods where electromagnetic radiation, in particular, light, can be used to photobiomodulate the activity of living cells to delay, diminish, retard or even reverse the structural and functional effects of aging of the skin and other living cells and tissues. In particular methods described for improving the appearance, structure, function of aging skin, including up and down regulating the genotypic markers for the phenotype of aging skin.
