Title: Procede de detection de virus, amorces correspondantes, et kit de criblage
Inventor: HART KEITH WILLIAM
IPC: G01N33/566
Filed: 2002-06-13
Abstract: L'invention concerne un procédé de détection et de typage de virus (par exemple, types de papillomavirus humain), sous PCR en temps réel, avec amorces fluorescentes à configuration d'amplicon autosondeur, selon les étapes suivantes: (IA) contact entre l'échantillon et l'amplicon ("amplicon autosondeur de virus"), lequel comprend, (i) une amorce de virus capable d'hybridation avec au moins une séquence nucléotidique virale cible et subissant une amplification dans les conditions d'amplification d'amorce pour donner un produit d'extension d'amorce de virus, (ii) une sonde de virus à séquence nucléotidique complémentaire d'une séquence cible du produit d'extension susmentionné et capable d'hybridation avec lui, à condition que l'amplicon autosondeur puisse assurer que la sonde de virus ne réagit pas à l'amplification dans les conditions d'amplification d'amorce, et (iii) un élément du système de signalisation de virus, sachant que le système en question est capable d'engendrer un signal - détectable à l'hybridation de la séquence sonde de virus avec le produit d'extension - et que ce signal indique la présence ou l'absence de la séquence nucléotidique virale cible dans l'échantillon; (IB) amplification du produit issu de (IA), dans les conditions d'amplification d'amorce, jusqu'à permettre l'établissement du signal détectable au-delà de l'étape (II); et (II) séparation du produit d'extension à partir de la séquence nucléotidique virale cible; hybridation de la sonde de virus avec la séquence cible du produit d'extension; et surveillance du système de signalisation. Il s'agit d'un procédé rapide, simple, spécifique, sensible, permettant d'évaluer la charge virale par cellule. Les résultats de plus de 100 réactions de typage de papillomavirus humain sur des lignées cellulaires, des biopsies et des échantillons de frottis vaginal sont fournis: par comparaison avec la technique de référence actuelle pour la détection et le typage du virus considéré, ces résultats présentent une valeur kappa de 0,89. Le procédé est également applicable à d'autres virus, du type virus vacuolant (SV40).

Abstract: A circulating switch comprises switch modules of moderate capacities interconnected by a passive rotator. Data is sent from a one switch module to another switch module either directly, traversing the rotator once, or indirectly through at least one intermediate switch module where the rotator is traversed twice. A higher capacity extended circulating switch is constructed from higher-capacity switch modules, implemented as common memory switches and having multiple ports, interconnected through a multiplicity of rotators preferably arranged in complementary groups of rotators of opposite rotation directions. A  polyphase circulating switch having a low switching delay is derived from a multi-rotator circulating switch by providing programmable rotators having adjustable relative rotator-cycle phases. A low delay high-capacity switch may also be constructed from prior-art medium-capacity rotator space switches with mutually phase-shifted rotation cycles.

Abstract: An enhanced 8-VSB reception system and E8-VSB data demultiplexing method, by which an E8-VSB signal can be stably received as well as a previous ATSC 8VSB  signal, is disclosed. Herein, the enhanced data are coded at 1/2 code rate and 1/4 code rate in the new E8-VSB transmission system compatible with the conventional ATSC 8VSB system, respectively. The 1/2 and 1/4 enhanced data are multiplexed by 164-byte packet unit according to the previously determined multiplexing format and further pre-processed to output as the format of the MPEG transport packet. And, the pre-processed enhanced data and the main data are multiplexed again by 188-byte packet unit according to the previously determined multiplexing format. The E8-VSB map information, which was inserted in the field sync section in the E8-VSB transmission system to be transmitted, is extracted to generate the information indicating the attributes of the respective E8-VSB  data. The normal data, 1/2 enhanced data, and 1/4 enhanced data are separated from each other to be decoded in the channel decoder.
