Patent number: 9849141Abstract: The present invention relates to the use of spironolactone for the preparation of a pharmaceutical composition intended for preventing and/or treating multiple sclerosis. Alternatively, the invention relates to the use of spironolactone directly in T-lymphocytes or dendritic cells obtained from a blood sample taken from a patient and then injected back into the circulation. Therefore, the present invention relates to the use of a composition comprising spironolactone that can be used in the treatment of multiple sclerosis, which covers the administration of spironolactone directly or lymphocytes pre-treated with spironolactone, or dendritic cells to individuals requiring such treatment. Spironolactone is an orally administered drug that is less expensive than many of the treatments available for MS and, furthermore, has the advantage of being a known compound already used in humans for extended periods and therefore the adverse effects thereof have been described in clinical studies.Type: GrantFiled: December 12, 2013Date of Patent: December 26, 2017Assignee: PONTIFICIA UNIVERSIDAD CATOLICA DE CHILEInventors: Alexis M.

Patent number: 9823112Abstract: Relative displacements related to a structure are measured for use of a feedback signal in real time for the structural monitor of active and semi-active vibration. The monitors reduce structural movement caused by any source of natural or artificial vibration. A pre-stressed axial element is installed between two different points of the structure using a fixed connector and a flexible one. As the structure vibrates in response to an external “source”, a relative displacement is caused between two connecting points of the axial element, which can be measured based on the rotation ? of the flexible connector of the axial element. Discrete displacement can be obtained in real time of the whole structure where the axial element is installed. A modal monitor through active or semi-active devices can improve the structural behavior in some cases.Type: GrantFiled: September 11, 2013Date of Patent: November 21, 2017Assignee: Pontificia Universidad Catolica de ChileInventors: René Zemp, Juan Carlos De La Llera
