Hitchhiking Through the Cytoplasm
Igor M. Kulić, Philip C. Nelson
We propose an alternative mechanism for intracellular cargo transport which results from motor induced longitudinal fluctuations of cytoskeletal microtubules (MT). The longitudinal…
New Measurements of DNA Twist Elasticity
Philip Nelson
The symmetries of the DNA double helix require a new term in its linear response to stress: the coupling between twist and stretch. Recent experiments with torsionally-constrained…
Straightening of Thermal Fluctuations in Semi-Flexible Polymers by Applied Tension
Udo Seifert, Wolfgang Wintz, Philip Nelson
We investigate the propagation of a suddenly applied tension along a thermally excited semi-flexible polymer using analytical approximations, scaling arguments and numerical simula…
The Role of Bilayer Tilt Difference in Equilibrium Membrane Shapes
Udo Seifert, Julian Shillcock, Philip Nelson
Lipid bilayer membranes below their main transition have two tilt order parameters, corresponding to the two monolayers. These two tilts may be strongly coupled to membrane shape b…
Dynamically-Stabilized Pores in Bilayer Membranes
J. David Moroz, Philip Nelson
Zhelev and Needham have recently created large, quasi-stable pores in artificial lipid bilayer vesicles [Biochim. Biophys. Acta 1147 (1993) 89]. Initially created by electroporatio…
