Patent CA-2485127-A1 (CA)
Inventor: GMIRYA YURIY
IPC: F16D1/08
Filed: 2004-02-11
Abstract: A spring clutch has an arbor, a spring, and a sleeve. The spring at least partially surrounds the arbor and has a first portion coupled to the arbor to confine relative rotation of the first portion and arbor about an axis. The sleeve at least partially surrounds the spring and cooperates with the spring.  The cooperation is sufficient so that an initial relative rotation between the arbor and sleeve in a first direction about the axis tends to uncoil the spring and bias the spring into firmer engagement with the sleeve. The cooperation is sufficient such that relative rotation in an opposite direction tends not to uncoil the spring and maintains the clutch in a disengaged condition.

Abstract: La présente invention concerne des procédés et compositions permettant la production de nouvelles molécules d'acide nucléique selon la technique SMaRT (spliceosome-mediated RNA trans-splicing). Ces compositions contiennent des molécules de pré-transépissage (PTM), conçues pour interagir avec une molécule d'ARN messager précurseur cible (pré-ARNm cible) et médier une réaction de transépissage donnant lieu à la production d'une nouvelle molécule d'ARN chimère (ARN chimère). En particulier, les PTM de cette invention peuvent être génétiquement modifiées, de sorte que ces molécules interagissent avec un pré-ARNm cible spécifique exprimé dans des cellules de la peau, afin de permettre la correction de défauts génétiques responsables d'une variété d'affections cutanées différentes ainsi que le codage d'une molécule ou protéine rapporteur pouvant présenter une valeur thérapeutique. Ces compositions contiennent également des systèmes de vecteurs recombinants pouvant exprimer lesdites PTM ainsi que des cellules exprimant ces PTM. Les procédés de cette invention consistent à mettre en contact ces PTM avec le pré-ARNm cible spécifique exprimé au sein de cellules de la peau dans des conditions permettant le transépissage d'une partie des PTM vers une partie du pré-ARNm cible, de manière à obtenir une molécule d'ARN chimère dans laquelle le défaut génétique dans le gène spécifique a été corrigé. Ladite invention est fondée sur le transépissage réussi du pré-ARNm du collagène XVII qui révèle ainsi l'utilité du transépissage dans la correction de défauts génétiques cutanés spécifiques. Les procédés et compositions de cette invention peuvent être utilisés en thérapie génique dans le traitement d'affections cutanées spécifiques, c.-à-d. de génodermatoses, de troubles de la fragilité épidermique, de troubles de la kératinisation, de troubles capillaires et de la pigmentation ainsi que de cancers de la peau.

Title: Split channel authenticity queries in multi-party dialog
Inventor: YACH DAVID P
IPC: H04L29/06
Filed: 2005-08-12
Abstract: Authenticity of a proposed future or current participant in a multi-party dialog is checked by splitting an authenticity challenge query into at least two portions wherein none of the portions individually contains sufficient information to fully define the challenge query. These separated portions are then sent to another dialog participant over at least two different communication channels thus enhancing the probability that a successive challenge response is authentic. The authenticity challenge query and splitting thereof into plural portions may include formation of a logical combination (e.g., exclusive-OR) of first and second data strings (one of which may be a challenge question) to produce a resultant third data string where the separated and separately communicated portions include the first and third data strings as separate portions as being sent over respectively different communication channels.
