Attractive membrane domains control lateral diffusion
No full textLipid membranes play a fundamental role in vital cellular functions such as signal transduction. Many of these processes rely on lateral diffusion within the membrane, generally a complex fluid containing ordered microdomains. However, little attention has been paid to the alterations in transport dynamics of a diffusing species caused by long-range interactions with membrane domains. In this paper, we address the effect of such interactions on diffusive transport by studying lateral diffusion in a phase-separated Langmuir phospholipid monolayer via single-particle tracking. We find that attractive dipole-dipole interactions between condensed phase domains and diffusing probe beads lead to transient confinement at the phase boundaries, causing a transition from two- to one-dimensional diffusion. Using Brownian dynamics simulations, the long-term diffusion constant for such a system is found to have a sensitive, Boltzmann-like, dependence on the interaction strength. In addition, this interaction strength is shown to be a strong function of the ratio of domain to particle size. As similar interactions are expected in biological membranes, the modulation of. diffusive transport dynamics by varying interaction strength and/or domain size may offer cells selective spatial and temporal control over signaling processes.Physic

No full textQuo vadis, CIUTI?
No full textLe présent article retrace le cheminement de la CIUTI depuis 50 ans, c’est-à-dire son développement en une organisation réputée ayant à son actif 40 membres en Europe et dans le monde. À ses débuts, la CIUTI avait certes comme but essentiel la promotion de la coopération entre ses membres (mobilité des étudiants et des enseignants, échange de connaissances), mais son autre objectif était de promouvoir la traductologie dans les universités en tant que discipline à part entière. L’auteur affirme qu’être membre de la CIUTI a une valeur symbolique qui confère, de ce fait, un capital social valorisant, sur les plans national et international, notamment en ce qui concerne le classement des instituts. En 1994, la CIUTI est devenue une association internationale régie par la loi belge ; en tant que telle, la CIUTI a voulu jouer son rôle en matière de formation afin d’influencer la politique langagière et traductionnelle européenne, en collaboration avec d’autres organisations internationales. Ses actions ont été facilitées par le fait que la CIUTI a aussi été déclarée ONG à Genève en 2003. Cependant, selon l’auteur, le développement interne de la CIUTI n’a pas suivi le même rythme que le rayonnement externe, indéniable, que cette association a connu et connaît encore en tant qu’important acteur international. Aussi, des modifications de la structure décisionnelle seront nécessaires, ainsi que la mise à disposition de moyens financiers liée à l’attribution de plus de pouvoir au Conseil de la CIUTI, de manière à permettre la mise en place d’une gestion professionnelle et efficace des affaires publiques. Une décision délicate incombe à la CIUTI : soit continuer à suivre le chemin déjà tracé et éviter toute forme de risque, soit prendre une voie nouvelle et accepter son rôle en tant qu’acteur clé dans notre ère de mondialisation.This article shows that within 50 years CIUTI has developed into a reputable organization now with 40 member institutes both within and outside of Europe. In the beginning CIUTI was devoted to promoting the cooperation between its members (mobility of students and trainers; exchange of knowledge), but was also anxious to anchor translation studies at universities as a scientific discipline in its own right. The author shows that CIUTI membership is of symbolic value and provides important social capital thus being of advantage to its members in their national and international ranking. In 1994, CIUTI became an international association (association internationale) under Belgian law and then began to play a role in education matters to influence European language and translation politics in collaboration with other international organizations. This was made easier by the fact that CIUTI was registered as a NGO in Geneva in 2003. However, according to the author of this article, the internal development of CIUTI has not kept pace with the external requirements of becoming a global player. That will require changes in its decision making structure and in the disposal of its financial resources by giving the Board (Conseil) more power to implement an appropriately efficient and professional public affairs strategy. CIUTI has a difficult decision to make, either to stay on the beaten track and avoid any risks or to forge a new future for itself and accept its role as a major global player
