Mechanically-Induced Morphogenetic Effects – MIME
In Drosophila embryos, mesoderm invagination is generated by mesoderm cells apical constrictions ensured by Fog dependent apical coalescence of Myo-II. This movement is preceded by unstable puslations of apex cells, associated to unstavle apical coalescence of Myo-II. We have suggested that the mech
Shared leadership and decision making in scattered organizations coping with risky situations – LEDEPAGOD
Overall, the research project aimed at studying the conditions and the impacts of shared leadership and decision-making, especially when: • Decision-making competences, knowledge and means are spread over a temporary or a newly formed organization; • Mutual knowledge between members is potenti
Role of the interactions between motoneurones and oligodendrocyte progenitor cells during the formation of spinal motor networks – OLIGOSPINE
Les progéniteurs d’oligodendrocytes (PO), ou cellules NG2, sont connus pour leur influence négative durant les tentatives de régénération axonale après une lésion de la moelle épinière. Ainsi, l’expression de « protéines inhibitrices associées à la myéline » (PIAMs) par les cellules de la lignée oli
Piezo 1 and arterial mechanotransduction – PIEZO
Blood vessels experience, sense, and respond to mechanical force. Despite the central physiological importance of arterial mechanotransduction, the molecular identities of the sensors and the signaling pathways involved have long remained elusive. For example, resistance arteries (small diameter) co
Hamiltonian Methods for the control of multidomain distributed parameter systems – HAMECMOPSYS
The control of infinite-dimensional dynamical systems, represented by systems of coupled Partial Differential Equations, is subject to a recently growing interest due to two major impulses. Firstly recent technological progress in material sciences induce an increased use of complex and heterogeneou
Grand colloque Biologie-Santé 2011
En plus des échanges suscités par les présentations des porteurs de projets ANR, le colloque a permis d’initier de passionnantes discussions à l’occasion de deux conférences et d’une table ronde. Le Pr Nilesh Samani a montré, avec l’exemple de la génétique des maladies coronariennes, comment les ét
Photo- and Electroinduced Bimodulation of Smart Surfaces – PHOEBUS
Nature, stability of all interconvertible photo- and electroinduced forms must be first fully characterize. For the first type of states, NMR technics is very helpful and for the second ones, cyclic voltametry and spectroelectrochemistry are the concerned methods. The feasibility of such multistate
Hybrid silica-chitin nano-composites through colloidal self-assembly – HYSIKIT
We recently described a new synthesis approach of hybrid nano-structured materials associating polysaccharide nanoparticles (chitin nanorods) with a silica matrix formed by siloxane oligomer condensation. We wish to pursue this research within the framework of the project HYSIKIT submitted to the Pr
Combinatorics: permutations and symmetric functions. – PSYCO
The objectives of the project PSYCO are centered around algebraic questions. In many cases, these algebraic questions lead to interesting enumerative questions, but our fundamental motivations belong to algebraic combinatorics. Selection of significant results. 1. Introduction non-ambiguous trees
The elite and the poor. Research of the "entre-soi" and representations of poverty in the areas of uppper social classes of three cities: Paris, Sao Paulo and Delhi – PSPD
/ / / / It is striking to note that the report to the poverty of the higher social classes has very rarely been studied as such. This may seem all the more surprising that the historian Louis Chevalier had established, research on the first half of the 19th century, as urban inequities could be expl
