To facilitate the study of Nogo-66 interaction with its neuronal receptors, and to explore therapeutic opportunities, the present invention provides mutant human Nogo-66 domain-based proteins that do not aggregate during isolation or purification procedures, and methods for using these proteins. Aggregates of Nogo-66 domain containing proteins do not effectively or efficiently bind to the NgR1 receptor, and therefore limit the utility of Nogo-66 domain-based reagents. To overcome aggregation problems, the invention provides proteins that comprise a mutant human Nogo-66 domain, wherein the cysteine at position 47 of the wild-type human Nogo-66 domain is mutated. The invention also provides for various Nogo-66 domain fusion reporter proteins that are able to bind to NgR1, and therefore can be used in high-throughput assays to identify drug candidate compounds that can block binding of the Nogo-66 domain to NgR1, indicating that these compounds may be potential therapeutic agents for neurodegenerative diseases and neuronal repair.
摘要:
The present invention is based on the identification of a G-protein coupled receptor (GPCR) that is expressed predominantly in the brain and placenta and nucleic acid molecules that encoded the GPCR, which is referred to herein as the hCAR protein and hCAR gene respectively (for human Constitutively Active Receptor). Based on this identification, the present invention provides: (1) isolated hCAR protein; (2) isolated nucleic acid molecules that encode an hCAR protein; (3) antibodies that selectively bind to the hCAR protein; (4) methods of isolating allelic variants of the hCAR protein and gene; (5) methods of identifying cells and tissues that express the hCAR protein/gene; (6) methods of identifying agents and cellular compounds that bind to the hCAR protein; (7) methods of identifying agents that modulate the expression of the hCAR gene; and (8) methods of modulating the activity of the hCAR protein in a cell or organism.

摘要:
A boxing or martial arts training and exercise device may include punching pads locationally displaced on a frame. Respective pads may be positioned in support on the frame for punching and kicking. Each pad can communicatively connect to one or more impact sensor. Each impact sensor can communicatively connect to a control unit. The control unit may be communicatively connected to a display. The impact sensor detects strikes to the pad. The impact sensor includes an accelerometer and a signal processor. The control unit includes an aggregator for receiving and logging strike metrics. The control unit directs sequences in the display according to a routine, and delivers indicators of strike metrics. The control unit includes a user interface for selection among sequences, as well as for selection of various menu items. A video of a human instructor or an animated avatar is viewable in a display.
摘要:
Described are devices, methods and systems useful for achieving occlusion of vascular vessels. Percutaneous procedures are used to occlude and obliterate the greater saphenous vein, for example in the treatment of varicose vein condition caused by venous reflux. Certain embodiments encompass the deployment of one or more vascular occlusion devices via a through-and-through percutaneous procedure that leaves the vascular occlusion device or devices in a through-and-through condition.

摘要:
A coated implantable medical device 10 includes a structure 12 adapted for introduction into the vascular system, esophagus, trachea, colon, biliary tract, or urinary tract; at least one coating layer 16 posited on one surface of the structure; and at least one layer 18 of a bioactive material posited on at least a portion of the coating layer 16, wherein the coating layer 16 provides for the controlled release of the bioactive material from the coating layer. In addition, at least one porous layer 20 can be posited over the bioactive material layer 18, wherein the porous layer includes a polymer and provides for the controlled release of the bioactive material therethrough. Preferably, the structure 12 is a coronary stent. The porous layer 20 includes a polymer applied preferably by vapor or plasma deposition and provides for a controlled release of the bioactive material. It is particularly preferred that the polymer is a polyamide, parylene or a parylene derivative, which is deposited without solvents, heat or catalysts, and merely by condensation of a monomer vapor.
