Patent CA-2082070-A1 (CA)
Inventor: SITES RICHARD L
IPC: G06F9/44
Filed: 1992-03-03
Abstract: Les valeurs possibles d'une adresse de destination calculée d'une instruction de transfert d'exécution sont retracées au moyen d'une recherche arrière dans un graphe de fluence d'un programme. Durant la recherche, une expression symbolique de l'adresse de destination est modifiée successivement pour refléter l'effet de chacune des instructions antérieures jusqu'à ce qu'elle représente une adresse absolue, ou jusqu'à ce que la recherche doive s'interrompre. La recherche doit s'interrompre, par exemple, quand on arrive à une instruction qui modifie la valeur de l'expression de façon indéterminée. Quand une exécution symbolique arrière atteint le point d'entrée d'un bloc du graphe de fluence, l'exécution symbolique arrière recule jusqu'à chaque bloc précédent qui n'a pas déjà été examiné en rapport avec l'instruction de transfert d'exécution. Par conséquent, on peut trouver plusieurs valeurs bien définies, ainsi qu'une valeur « inconnue » pour une adresse de destination calculée. Dans la concrétisation privilégiée de l'invention, l'exécution symbolique arrière est exécutée durant la construction du graphe de fluence afin de localiser les instructions additionnelles.  mesure que celles-ci sont localisées, de nouveaux blocs et de nouveaux trajets entre les blocs sont ajoutés au graphe de fluence. L'exécution symbolique arrière est répétée quand les nouveaux trajets peuvent donner des valeurs additionnelles pour les adresses de destination calculées.

Title: Monoclonal antibody against the gag protein precursor p55 of human immunodeficiency virus
Inventor: NOLLI MARIA L C
IPC: C07K19/00
Filed: 1991-05-21
Abstract: A monoclonal antibody showing specific reactivity against the precursor protein named p55 which is cleaved by HIV-1 protease into smaller structural protein. The antibody of this invention shows specific reactivity against an epitope of the p55 protein which corresponds to the cleavage site by HIV-1 protease which generates the p24 and p17 structural proteins. The specific antibody is an IgG1 protein with a molecular weight of the order of 150,000 Dalton produced by a hybridoma deriving from the fusion of spleen cells of animals immunized with a cloned fused protein containing a p55 fragment which includes the p24/p17 cleavage site and a myeloma cell line. The specific antibody is useful for monitoring HIV-1 exposure, for isolation and purification of natural or synthetic peptides containing the p55 sequence or a fragment thereof which include the p24/p17 cleavage site and for screening substances for HIV-1 protease inhibitory activity.
