A time-varying observer for linear systems with asynchronous discrete-time measurements
2017
International audience; In this paper we propose a time-varying observer for a linear continuous-time plant with asynchronous discrete-time measurements. The proposed observer is contextualized in the hybrid systems framework providing an elegant setting for the proposed solution. In particular some theoretical tools are provided, in terms of LMIs, certifying asymptotic stability of a certain compact set where the estimation error is zero. Moreover the case of asynchronous measurements is considered, i.e. when the measurements are not provided in well defined time instants, but they occur at an arbitrary time in a certain time interval. A design procedure based on the numerical solution of …
Conceptos básicos en biología molecular relacionados con la genética y la epigenética
2017
Resumen La observacion de que «lo mismo no sirve para todos» en la prevencion y el tratamiento de las enfermedades cardiovasculares, entre otras, ha propulsado el concepto de medicina de precision. Su objetivo es proporcionar las mejores intervenciones basadas en la informacion adicional que aporta el genoma. El genoma humano se compone de miles de millones de pares de bases que contienen un codigo que controla como se expresan los genes. Este codigo depende de reguladores no estaticos que rodean el ADN y constituyen el epigenoma. Ademas, los factores ambientales tambien desempenan un papel importante en esta compleja regulacion. Se presenta una perspectiva general sobre los conceptos basic…
El suero de seno coronario tras un infarto de miocardio induce angiogénesis y reparación de la obstrucción microvascular. Implicación del factor indu…

Resumen Introduccion y objetivos El objetivo es estudiar la angiogenesis coronaria inducida por el suero coronario y la implicacion del factor inducible por hipoxia-1A (FIH-1A) en la reparacion de la obstruccion microvascular (OMV) tras un infarto agudo de miocardio (IAM). Metodos Se indujo un IAM en cerdos mediante oclusion coronaria durante 90 min. Se dividio a los animales entre 1 grupo de control y 4 grupos con IAM: sin reperfusion y 1 min, 1 semana y 1 mes tras la reperfusion. Se cuantificaron la OMV y la densidad microvascular. Se determino la capacidad angiogenica del suero coronario mediante una prueba de tubulogenesis in vitro. Se determinaron las concentraciones circulantes del FI…

Lipids contained in the plasma membrane of platelets play an important role in platelet function. Modifications in the lipid composition can fluidify or rigidify the environment around embedded receptors, in order to facilitate the access of the receptor by the drug. However, data concerning the lipid composition of platelet plasma membrane need to be updated. In addition, data on the impact of drugs on plasma membrane composition, in particular antiplatelet agents, remain sparse. After isolation of platelet plasma membrane, we assessed, using lipidomics, the effect of ticagrelor, a P2Y12 antagonist, and its active metabolite on the lipid composition of these plasma membranes. We describe t…
Recombinant factor VIII: past, present and future of treatment of hemophilia A.
2018
The development of recombinant factor VIII (rFVIII) was initially driven by the necessity to treat hemophilia A (HA) patients with FVIII concentrates without the risk of transmitting infectious agents. Over the last three decades the safety of rFVIII has been further improved by completely removing animal or human proteins from the manufacturing process, so that patients would not be exposed to known or emerging pathogens. Recent efforts have concentrated on improving the expression of rFVIII, reducing its immunogenicity and enhancing its pharmacokinetic (PK) behavior. These new goals have been possible thanks to the develop-ment of biotechnology and a better knowledge of the function and s…
