Filed: 1999-02-25
Abstract: Les adénovirus recombinés constituent un système polyvalent utile pour des études d'expression de gènes et des applications thérapeutiques. L'invention concerne une stratégie simplifiant la formation et la production de tels virus. On forme un plasmide adénoviral recombiné avec un minimum de manipulations enzymatiques en utilisant une recombinaison homologue dans des bactéries plutôt que dans des cellules eucaryotes. Suite à des transfections de ces plasmides dans une lignée de cellules d'encapsidation de mammifère, une production virale peut être menée de façon adéquate à l'aide d'une protéine fluorescente verte, codée par une gène incorporé dans le squelette viral. Des virus homogènes peuvent être obtenus au moyen de ce procédé sans purification de plage de lyse. Ce système permet d'accélérer le processus de formation et la mise en oeuvre d'essais d'adénovirus recombinés.

Patent CA-2331212-A1 (CA)
Title: Programming call-processing application in a switching system
Inventor: HEBERT MARK P
IPC: H04Q3/00
Filed: 1999-06-03
Abstract: The L4 application in the switch is expanded to permit functions previously performed exclu-sively in the L5 protocol application. Moreover, the L4 application is programmable by the system operator so that the system operator may expand the predefined set of L4 call management opera-tions to accommodate his call processing require-ments. Overall supervision of the call-management operations was previously limited to the L5 applications. However, the ability to program the L4 application enables the system operator to decide which call processing operations will be managed by the L5 applications and which operations will be managed by the L4 application. The system opera-tor may thus define, in the L4 application, a propri-etary call model that instructs the switching node to manage all incoming calls, or the system operator may specify the call model on a channel by channel basis. The latter arrangement programs the switch-ing node to use different call-processing protocols among the various channels. In addition, the user may either re-define or define entirely new appli-cation programming interface (API) calls for com-munications between the host and switching node and/or between the switching node and ports.

Inventor: EL-RATAL WISSAM H
IPC: G06F17/10
Filed: 2001-12-06
Abstract: A method is disclosed for calibrating a mathematical model of a component using prototype full-field experimentally collected deformation/strain data. Specifically, the method involves obtaining actual experimental field data using strain sensitive coating material and then mapping said data on a CAD mesh model. The analytical mesh model is then compared to a finite element model that is based on theoretical values referred to as boundary conditions. The finite element model boundary conditions are then calibrated to reflect the values derived from the experimental field measurements. Once calibrated, the model can be used to optimize design of components.

Title: Technique for returning to directory assistance or information services provider upon command
Inventor: KEPLER MICHAEL A
IPC: H04W4/00
Filed: 1994-08-02
Abstract: A cellular telephone subscriber who wishes directory assist nce services is connected in the conventional manner to an operator who identifies a destination telephone number desired by the subscriber. As in the prior art, the operator then initiates a call connecting the subscriber to the destination telephone number. However, rather than dropping all further involvement with the call, the preferred embodiment of the present invention continually monitors the connection thereby established for a predetermined DTMF signal issued by the customer, such as that obtained by pressing the "*" button. If such a signal is detected, the customer is transferred back to a directory assistance operator, who can then provide whatever further assistance is needed (e.g. redialing a busy number, or providing further directory assistance). Billing information for the calls originated by the directory assistance operator on the subscriber's behalf is logged in a database at the directory assistance center. This data is thereafter provided to the cellular carrier, permitting it to bill the subscriber for calls originated by the directory assistance operator.

Patent CA-2371462-A1 (CA)
Title: Modified protein matrices
Inventor: SCHENSE JASON C
IPC: A61P17/00
Filed: 2000-04-24
Abstract: Matrices formed of materials which bind to growth factors, directly or indirectly, are used for controlled delivery of the growth factors, especially for use in tissue repair and/or regeneration. The matrices may have heparin bound thereto ionically or covalently, or heparin-like binding sites incorporated in the matrix forming materials. The heparin or heparin-like binding sites can bind to the growth factors. The ratio of binding sites to peptides or growth factors can be used to vary the kinetics of the binding, thereby providing a means to increase or decrease the rate of association of the growth factors with the matrix and thus the rate of delivery. A ratio of at least 1:1 heparin to growth factor is preferably used. Increasing the ratio decreases the rate of release. The dissociation kinetics of low affinity heparin-binding proteins are relatively fast, but a high number of binding sites allows rebinding of the growth factor before it can diffuse out of the matrix. Release can occur by diffusion of the growth factor out of the matrix prior to rebinding, or it can occur if the growth factor encounters a cell surface receptor before rebinding to a heparin site. The most preferred matrix is heparin or peptides containing heparin binding sites bound to fibrin, capable of attaching heparin, a heparin-like polysaccharide, or a heparin-like polymer, and a growth factor or peptide fragment thereof having a basic domain that binds heparin. The matrices can be implanted directly, alone or in combination with cells,or implanted and seeded with cells, at a site where tissue repair or regeneration is desired. A particularly preferred application is in regeneration and repair of nerves. The matrices can be coated on medical devices and implants. The matrices most preferably encourage and promote cellular ingrowth.
