Publication number: 20210347890Abstract: Disclosed is CD31shed for use as a molecular imaging target in the molecular imaging of an inflammatory condition. Administering the radiolabeled peptide P8RI as CD31shed ligand in different rat models of inflammation indeed showed that CD31shed is present on activated cells in a quantity allowing a detectable signal, whereas the noise signal corresponding to CD31shed present on activated circulating cells and on other organs or cells not involved in inflammation was little. Also disclosed is a labeled CD31shed ligand and the use thereof as a molecular imaging agent in the molecular imaging of an inflammatory condition. The molecular imaging of inflammatory sites particularly allows determining whether a subject suffers from or is at risk of having an inflammatory condition or is at risk of recurrence of an inflammatory condition after an anti-inflammatory treatment.Type: ApplicationFiled: July 19, 2021Publication date: November 11, 2021Inventors: Sylvie BAY, Antonino NICOLETTI, Dominique LE GULUDEC, Jonathan VIGNE, Giuseppina CALIGIURI

Patent number: 10875550Abstract: A table top is for a vehicle compartment accommodating passengers, in particular a rail vehicle. The table top includes a stationary part connected to the vehicle and a moving tray located across from a passenger chair or seat. The tray is movable along an axis of rotation parallel to a plane of the table top. The table top includes a chassis on which the tray is mounted. The chassis is translatable relative to the stationary part along an axis parallel to the plane of the tray and perpendicular to the axis of rotation. In a deployed configuration, the tray is deployed jointly with the stationary part, with the chassis maximally separated from the stationary part. In a folded configuration, the tray is pivoted along its axis of rotation in an inclined position relative to the stationary part, with the chassis minimally separated from the stationary part.Type: GrantFiled: October 15, 2019Date of Patent: December 29, 2020Assignee: ALSTOM TRANSPORT TECHNOLOGIESInventor: Dominique Le Corre
