Computing the volume enclosed by a periodic surface and its variation to model a follower pressure
Rahimi Lenji, Mohammad; Zhang, Kuan; Arroyo Balaguer, Marino (2015-03-01)
Article
Accés obertIn modeling and numerically implementing a follower pressure in a geometrically nonlinear setting, one needs to compute the volume enclosed by a surface and its variation. For closed surfaces, the volume can be expressed ... -
Confined bilayers passively regulate shape and stress
Staykova, M.; Arroyo Balaguer, Marino; Rahimi Lenji, Mohammad; Stone, H.A. (2013-01)
Article
Accés obertLipid membranes are commonly confined to adjacent subcellular structures or to artificial substrates and particles. We develop an experimental and theoretical framework to investigate the mechanics of confined membranes, ... -
Curved fluid membranes behave laterally as an effective viscoelastic medium
Rahimi Lenji, Mohammad; DeSimone, Antonio; Arroyo Balaguer, Marino (2013-08-21)
Article
Accés restringit per política de l'editorialThe lateral mobility of membrane inclusions is essential in biological processes involving membrane-bound macromolecules, which often take place in highly curved geometries such as membrane tubes or small organelles. Probe ... -
Interplay of packing and flip-flop in local bilayer deformation. How phosphatidylglycerol could rescue mitochondrial function in a cardiolipin-deficient yeast mutant
Khalifat, Nada; Rahimi Lenji, Mohammad; Bitbol, Anne-Florence; Seigneuret, Michel; Fournier, Jean Baptiste; Puff, Nicolas; Arroyo Balaguer, Marino; Angelova, Miglena I. (2014-08-19)
Article
Accés obertn a previous work, we have shown that a spatially localized transmembrane pH gradient, produced by acid micro-injection near the external side of cardiolipin-containing giant unilamellar vesicles, leads to the formation ... -
Shape dynamics, lipid hydrodynamics, and the complex viscoelasticty of bilayer membranes
Rahimi Lenji, Mohammad; Arroyo Balaguer, Marino (2012-07)
Article
Accés restringit per política de l'editorialBiological membranes are continuously brought out of equilibrium, as they shape organelles, package and transport cargo, or respond to external actions. Even the dynamics of plain lipid membranes in experimental model systems ... -
Shape transformations of lipid bilayers following rapid cholesterol uptake
Rahimi Lenji, Mohammad; Regan, David; Arroyo Balaguer, Marino; Subramaniam, Anand Bala; Stone, Howard A.; Staykova, M (2016)
Article
Accés obertHigh cholesterol levels in the blood increase the risk of atherosclerosis. A common explanation is that the cholesterol increase in the plasma membrane perturbs the shape and functions of cells by disrupting the cell ...
