Title: Bovine viral diarrhea virus serum antigen capture immunoassay
Inventor: HUCHZERMEIER ROY
IPC: G01N33/569
Filed: 1998-09-23
Abstract: The invention disclosed herein presents an antigen-capture immunoassay that utilizes serum, plasma, milk, urine, saliva, or other bodily fluid samples to identify cattle infected with the Bovine Viral Diarrhea Virus (BVDV). The results of this assay allow an effective, reliable quick and cost efficient way to identify, and thereby remove infected cattle and/or other ruminants from otherwise uninfected herds. The BVD virus causes an acute enteric disease with a variety of clinical manifestations, and is closely related to sheep border disease virus (BDV) and hog cholera virus (HCV). The traditional method of detecting infected animals, including persistently infected (PI) carriers, has been through the use of virus isolation procedures. While this older test methodology can detect infected animals, the virus isolation test can only be performed by highly trained technicians in a highly specialized laboratory facility. The kit disclosed herein uses ELISA methodology, employs the BVDV antigen specific monoclonal antibody 15.c.5, and requires at least 100 µl of sample per assay.

IPC: G02F1/35
Filed: 1998-09-25
Abstract: La présente invention concerne une boucle-miroir (10) optique non-linéaire (16) se combinant à un compresseur d'impulsions. Cette boucle-miroir non-linéaire, qui reçoit d'une part des impulsions de commande et d'autre part des impulsions de données, retransmet des impulsions de données en respectant des rapports de chevauchement entre les différentes impulsions de commandes et de données. Le compresseur comprime au moins, soit les impulsions de données, soit les impulsions de commandes, et ce, de façon à augmenter l'efficacité de la transmission des impulsions de données sélectionnées et de réduire la diaphonie avec les impulsions de données restantes.

Title: Telephone rate managing system
Inventor: MIYAKE TOMOMI
IPC: H04M17/02
Filed: 1999-03-05
Abstract: A telephone rate managing system comprises an autodialer (1) having means for generating PB tones, such as of the telephone number of a connection telephone company or the user ID, a store processing terminal (30) provided in a store to deal with autodialer, a POS terminal (40), and a managing host computer (100) of the telephone company, all being interconnected through communication lines. Merchandise information of the autodialer dealt with is sent to the host computer and stored in it. When a call using the autodialer is made, the host computer performs a subtraction processing of the prepaid call charge, in accordance with the charge, from the merchandise information of the autodialer stored in the host computer. Even though coupon information is not written in the autodialer itself, auto-dialing call is thus possible and payment of telephone charge is possible at a store which deals with autodialers.

Title: Clonage de choline / ethanolaminephospho - transferases humaines, synthese de phosphatidyl - choline et de phosphatidyle - thanolamine et du facteur d'actival
Inventor: HENNEBERRY ANETTE
IPC: C12Q1/6883
Filed: 1999-06-07
Abstract: Il est rendu compte, dans cette invention, du premier clonage et de l'expression, à partir d'un mammifère source, de protéines capables de catalyser des réactions de la cholinephosphotransférase et de l'éthanolaminephosphotransférase (hCEPT1 et hCEPT2). Les deux régions codantes permettent de prévoir des protéines hautement hydrophobes de 43 à 46,5 kDa ayant plusieurs domaines prévus de recouvrement membranaire. Un motif CDP-alcool phosphotransférase DG(x)2AR(x)8G(x)3D(x)3D a été identifié dans les hCEPT1 et hCEPT2, cholinephosphotransférase et éthanolaminephospho-transférase, (ainsi que dans plusieurs autres enzymes synthétisant des lipides, lesquelles enzymes catalysent la formation de liaison phospho-ester par le déplacement de la CMP depuis un CDP-alcool par un second alcool). Il a été utilisé une mutagenèse dirigée sur un site pour différencier les restes responsables d'une activité cholinephosphotransférase contre éthanolaminephosphotransférase. La mutation de la glycine 156 de hCEPT1 a supprimé l'activité de l'éthanolaminephosphotransférase alors que celle de la cholinephosphotransférase se maintenait intacte.
