Abstract: We conducted feline calicivirus (FCV) inhibition experiment with two anti-viral aminohydrolases, asparaginase and glutaminase. We found that in the presence of 8 units and 4 units/ml of asparaginase, about 90% of FCV  replication was inhibited. In contrast, glutaminase showed no significant inhibition effect on the virus replication. We have also shown that asparaginase did not inhibit the replication of adenovirus suggesting that the inhibition was specific. Our results implicated that asparaginase could be used as a candidate for anti-FCV drug development.

Abstract: Système et méthode de mise à jour d'un contexte de protocole de données à paquets, comme un contexte PDP (Protocole de données à paquets) Un dispositif mobile communique dans un contexte de protocole de données à paquets. S'il n'y a pas eu d'activité de données dans le contexte de protocole de données à paquets pendant une certaine durée, le réseau peut alors désactiver le contexte de protocole de données à paquets. Le dispositif mobile peut rétablir le contexte de protocole de données à paquets; cependant rétablir excessivement le contexte de protocole de données à paquets impose une charge sur le réseau. D'après un mode de réalisation de l'application, le dispositif mobile détermine la durée d'arrêt, par exemple en mesurant la durée d'arrêt. Lors d'inactivité des données pendant une période proche de la durée d'arrêt, le dispositif mobile transmet un paquet dans le contexte de protocole de données à paquets pour tenir à jour le contexte de protocole de données à paquets. Conséquemment, la charge sur le réseau peut être réduite en obtenant une fréquence convenable de transmission de courtes données à partir du dispositif mobile.

Title: Regulation of antigen presentation
Inventor: HUMPHREYS ROBERT E
IPC: C07K7/08
Filed: 1994-05-18
Abstract: The subject disclosure relates to the identification of mutations in the I i protein which result in an alteration of the endoprotease cleavage pattern of the mutant I i as compared with the endoprotease cleavage pattern of the wild type product. Methods for the identification of such mutants, and the mutants themselves are useful for the identification of classes of compounds to be further tested for immunomodulatory activity. A specific example of such a use is the screening of small organic compounds for the ability to bind to an intermediate in the I i endoprotease processing pathway. A small organic molecule having the ability to bind to such an intermediate can be further screened for the ability to modulate antigen presentation.
