Publication number: 20230181539Abstract: Coronaviridae is a family of enveloped, positive-sense, single-stranded RNA viruses. The emergence of a new beta-coronavirus SARS-CoV-2 has led to a major health-related crisis associated with a significant mortality in intensive care units, due to the pulmonary complications of COVID-19. The inventors showed that BAY-2402234 is suitable for inhibiting replication of coronavirus and thus would be suitable for the treatment of infections mediated by said type of virus.Type: ApplicationFiled: May 19, 2021Publication date: June 15, 2023Inventors: Pierre-Olivier VIDALAIN, Antoine NOUGAIREDE, Franck TOURET, Patrice ANDRE, Vincent LOTTEAU, Xavier Nicolas LAMBALLERIE, Yves Louis JANIN

Patent number: 11441779Abstract: The provision of air passage holes through a wall of a gas turbomachine combustion chamber. Multi-perforations are virtually positioned and distributed, even in a first safety zone without air passage openings. Multi-perforations with a virtual inlet or outlet in this first security zone are virtually removed. According to certain criteria, at least some of said removed multi-perforations are then virtually reintegrated, and, from then on a perimeter passing through the virtual inlets and outlets of all the multi-perforations present is defined, in the direction of a primary or dilution hole to be installed, a modified safety zone is defined, then, respecting around said hole and with the freedom to reposition it within this limit, the shape of this hole is redefined.Type: GrantFiled: April 16, 2020Date of Patent: September 13, 2022Assignee: Safran Aircraft EnginesInventors: François Pierre Ribassin, Patrice André Commaret, Romain Nicolas Lunel, Christophe Pieussergues

Publication number: 20210085662Abstract: The inventors surprisingly found that FXR plays a determinant role in the maintenance of viral episome in cells from tissues that are not specialized in bile salt synthesis and transport as the liver or the intestine. In particular, the inventors show that FXR agonist could be suitable for inhibiting the replication of viruses (e.g. BKV and HIV-1) that persist in the cell in an episomal and extrachromosomal form of DNA. Accordingly the present invention relates to a method of reducing persistence and expression of an episomal virus in a subject in need thereof comprising administrating to the subject a therapeutically effective amount of a FXR agonist.Type: ApplicationFiled: March 29, 2018Publication date: March 25, 2021Inventors: Vincent LOTTEAU, Patrice ANDRE
