Journal ArticleDOI
Lateral mobility of proteins in liquid membranes revisited.
Yann Gambin,R. López-Esparza,Myriam Reffay,Emma Sierecki,Nir S. Gov,M. Genest,Robert S. Hodges,Wladimir Urbach +7 more
TL;DR: It is shown in this work that, for several integral proteins spanning a large range of sizes, the diffusion coefficient is strongly linked to the protein dimensions.
Journal ArticleDOI
Anomalous diffusion in ‘‘living polymers’’: A genuine Levy flight?
TL;DR: It is argued that the tracer provides the first experimental realization of a random walk for which the second moment of the jump-size distribution fails to exist ( ``Levy flight'').
Journal ArticleDOI
Entangled versus multiconnected network of wormlike micelles
A. Khatory,F. Kern,François Lequeux,Jacqueline Appell,Grégoire Porte,N. Morie,Albrecht Ott,Wladimir Urbach +7 more
TL;DR: In this paper, the authors propose a method for the Dynamique des Phases Condensi?es (DPDC) of the URA du CNRS No. 233, Universite des Sciences et Techniques du Languedoc, 34095 Montpellier cedex 05, France.
Journal ArticleDOI
Unfolding and Refolding of Bovine Serum Albumin at Acid pH: Ultrasound and Structural Studies
N. El Kadi,Nicolas Taulier,J.-Y. Le Huerou,M. Gindre,Wladimir Urbach,I. Nwigwe,Peter C. Kahn,Marcel Waks +7 more
TL;DR: Sorbol, at concentrations from 0 to 2 M, led to the progressive restoration of BSA volume and compressibility values, as well as a substantial recovery of its original alpha-helix content, implying that the compressibility variation observed reflects the conformational changes during the transition.
Journal ArticleDOI
Perfluorooctyl Bromide Polymeric Capsules as Dual Contrast Agents for Ultrasonography and Magnetic Resonance Imaging
Emilia Pisani,Nicolas Tsapis,Belfor Galaz,Belfor Galaz,Mathieu Santin,Romain Berti,Nicolas Taulier,Erol Kurtisovski,Olivier Lucidarme,Michèle Ourévitch,Bich Thuy Doan,Jean-Claude Beloeil,Brigitte Gillet,Wladimir Urbach,S. Lori Bridal,Elias Fattal +15 more
TL;DR: Results show initial feasibility for development of these capsules toward a dual‐modality contrast agent and injections of nanocapsules in mice in vivo reveal that the initial bolus passage presents significant ultrasound enhancement of the blood pool during hepatic imaging.
