Membrane Dynamics in M(atrix) Theory [PDF]
Nucl.Phys.B491:184-200,1997, 1996 We analyze some of the kinematical and dynamical properties of flat infinite membrane solutions in the conjectured M theory proposed by Banks, Fischler, Shenker and Susskind. In particular, we compute the long range potential between membranes and anti-membranes, and between membranes and gravitons, and compare it with the supergravity results. We also

A free boundary problem modeling electrostatic MEMS: II. nonlinear bending effects [PDF]
Mathematical Models and Methods in Applied Sciences 24, 13 (2014)
2549--2568, 2013 Well-posedness of a free boundary problem for electrostatic microelectromechanical systems (MEMS) is investigated when nonlinear bending effects are taken into account. The model describes the evolution of the deflection of an electrically conductive elastic membrane suspended above a fixed ground plate together with the electrostatic potential in the ...

Curvature-driven feedback on aggregation-diffusion of proteins in lipid bilayers [PDF]
arXiv, 2021 Membrane bending is an extensively studied problem from both modeling and experimental perspectives because of the wide implications of curvature generation in cell biology. Many of the curvature generating aspects in membranes can be attributed to interactions between proteins and membranes.

Indirect interactions of membrane-adsorbed cylinders [PDF]
, 2003 Biological and biomimetic membranes often contain aggregates of embedded or adsorbed macromolecules. In this article, the indirect interactions of cylindrical objects adhering to a planar membrane are considered theoretically. The adhesion of the cylinders causes a local perturbation of the equilibrium membrane shape, which leads to membrane-mediated ...

Mitochondrial membrane potential is regulated by vimentin intermediate filaments
The FASEB Journal, 2015 This study demonstrates that the association of mitochondria with vimentin intermediate filaments (VIFs) measurably increases their membrane potential.

Potential and pH dependence of the buried interface of membrane-coated electrocatalysts [PDF]
arXiv, 2020 Semipermeable silica membranes are attractive as protective coatings for metal electrocatalysts such as platinum but their impact on the catalytic properties has not been fully understood. Here, we develop a first principles formalism to investigate how silica membranes interact with the surface of platinum metal electrocatalysts to develop a better ...

Cellular binding of nanoparticles disrupts the membrane potential.
RSC Advances, 2015 All cells generate an electrical potential across their plasma membrane driven by a concentration gradient of charged ions. A typical resting membrane potential ranges from -40 to -70 mV, with a net negative charge on the cytosolic side of the membrane ...

Dimethyl Sulfoxide Damages Mitochondrial Integrity and Membrane Potential in Cultured Astrocytes
PLoS ONE, 2014 Dimethyl sulfoxide (DMSO) is a polar organic solvent that is used to dissolve neuroprotective or neurotoxic agents in neuroscience research. However, DMSO itself also has pharmacological and pathological effects on the nervous system.

Diffusing proteins on a fluctuating membrane: Analytical theory and simulations [PDF]
, 2010 Using analytical calculations and computer simulations we consider both the lateral diffusion of a membrane protein and the fluctuation spectrum of the membrane in which the protein is embedded. The membrane protein interacts with the membrane shape through its spontaneous curvature and bending rigidity.

Open Biology, 2012 Summary Missense mutations in PTEN-induced kinase 1 (PINK1) cause autosomal-recessive inherited Parkinson's disease (PD). We have exploited our recent discovery that recombinant insect PINK1 is catalytically active to test whether PINK1 directly ...
