Patent number: 11912645Abstract: The invention is based on the discovery of a new bacterial compound with analgesic properties which could be used as a new tool for the treatment of pain disorders such as visceral pain. Studying the mechanisms implicated in analgesic properties of the probiotic Escherichia coli strain Nissle 1917 (EcN), inventors characterized, the amino fatty acids produced by EcN, which display the Ecn analgesic properties. One of these compounds inhibits the hypersensitivity to colorectal distension induced by capsaicin, which is a very powerful nociceptive compound and acts via the GABA B receptor. Furthermore, inventors demonstrate that this compound is able to cross the cellular epithelial barrier (such as the intestinal epithelium). Thus, the invention relates to a lipopetide compound, derived from gamma-aminobutyric acid. The invention also relates to a lipopeptide compound according to the invention for the treatment of treating pain disorder, such as somatic pain and visceral pain.Type: GrantFiled: April 27, 2018Date of Patent: February 27, 2024Assignees: INSERM (INSTITUT NATIONAL DE LA SANTÉ ET DE LA RECHERCHE MÉDICALE), CENTRE HOSPITALIER UNIVERSITAIRE DE TOULOUSE, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE—CNRS—, ECOLE NATIONALE VETERINAIRE DE TOULOUSE, UNIVERSITE PAUL SABATIER TOULOUSE III, INSTITUT NATIONAL DE RECHERCHE POUR L'AGRICULTURE, L'ALIMENTATION ET L'ENVIRONNEMENT, UNIVERSITE DE MONTPELLIER, ECOLE NATIONALE SUPERIEURE DE CHIMIE DE MONTPELLIERInventors: Nicolas Cenac, Justine Bertrand-Michel, Teresa Perez-Berezo, Thierry Durand, Jean-Marie Galano, Julien Pujo, Eric Oswald, Patricia Martin, Pauline Le Faouder, Alexandre Guy

Patent number: 11415061Abstract: A power distribution device between an electric starter of a turbomachine and an electric machine toward a shaft of the turbomachine, including the electric starter, the electric machine, and a controller for controlling the electric machine. An epicyclic train reducer includes a first element intended to be coupled to the shaft, a second element coupled to the electric starter, and a third element intended to be rotated by the electric machine. The controller is configured to rotate the third of the three elements so as to obtain two bearings of reduction ratios of the speeds between the first of said three elements and the second of the three elements. The controller is configured to drive the torque of the third of the three elements in accordance with a determined output torque.Type: GrantFiled: July 23, 2020Date of Patent: August 16, 2022Assignee: SAFRAN AIRCRAFT ENGINESInventors: Huguette De Wergifosse, Nicolas Bertrand Georges De Blois, Clement Dupays, Pierre Gerard Lalonde

Publication number: 20110306055Abstract: The present invention provides a novel method for diagnosing, monitoring, prognosing and staging Lymph Node (LN) status in colorectal cancer (CRC) that is more sensitive and accurate than conventional detection technologies such as histopathology. The Guanylyl Cyclase C (GCC) gene is specifically expressed in apical epithelial cells of the GI tract from the duodenum to the rectum and the detection of GCC mRNA in LNs is indicative of the presence of metastases. Quantitative RT-PCR (RT-qPCR) detection of GCC mRNA to identify the presence of colorectal cancer (CRC) cells in LNs has the potential to aid in CRC staging. When used in combination with glucuronidase B (GUSB), accurate quantification of GCC can be achieved with less than a 2-fold variation between intact and highly degraded RNA specimens.Type: ApplicationFiled: February 24, 2010Publication date: December 15, 2011Applicant: DIAGNOCURE INC.Inventors: Jean-Francois Haince, Guillaume Beaudry, Genevieve Garon, Michel Houde, Timothy J.
