Curvature-Driven Lipid Sorting in a Membrane Tubule
Hongyuan Jiang and Thomas R. Powers
Motivated by recent experiments that implicate the mechanical properties of membranes in lipid sorting, we examine the interplay of lipid composition and curvature in membrane tubules. We study how the coupling between membrane composition and membrane bending stiffness and tension affects tubule fo ... [Phys. Rev. Lett. 101, 018103 (2008)] published Thu Jul 3, 2008.
Failure of feedback as a putative common mechanism of spreading depolarizations in migraine and stroke
Markus A. Dahlem, Felix M. Schneider, and Eckehard Scholl
The stability of cortical function depends critically on proper regulation. Under conditions of migraine and stroke a breakdown of transmembrane chemical gradients can spread through cortical tissue. A concomitant component of this emergent spatio-temporal pattern is a depolarization of cells detect ... [Chaos 18, 026110 (2008)] published Fri Jun 27, 2008.
