TLDR
The relaxation time as well as relaxation strength increased anomalously in the vicinity of the gel-to-liquid crystal transition of 41.5 degrees C, which represents the first definite evidence of the critical slowing down in the lipid bilayer.About:

Journal ArticleDOI
Physical properties of the fluid lipid-bilayer component of cell membranes: a perspective.
TL;DR: The motivation for this review arises from the conviction that, as a result of the mass of experimental data and observations collected in recent years, the study of the physical properties of membranes is now entering a new stage of development.
Journal ArticleDOI
On soliton propagation in biomembranes and nerves.
TL;DR: The lipids of biological membranes and intact biomembranes display chain melting transitions close to temperatures of physiological interest, and it is shown that this feature leads to the possibility of soliton propagation in such membranes.
Journal ArticleDOI
Rigidification of Neutral Lipid Bilayers in the Presence of Salts
TL;DR: It is found that both salts lead to a significant increase of order within the lipid bilayer, leading to a decrease of bilayer elasticity and shift of main phase transition temperature.
Journal ArticleDOI
Passive ion permeability of lipid membranes modelled via lipid-domain interfacial area
TL;DR: Insight indicates that there is no need for aqueous pore-formation to explain the experimental observation of a dramatic increase in ion conductance subsequent to electric pulses, and new insight is provided into the microphysical mechanisms of reversible electric breakdown.
Journal ArticleDOI
On the action potential as a propagating density pulse and the role of anesthetics
TL;DR: The thermodynamic theory of nerve pulses suggests an explanation for the famous Meyer-Overton rule that states that the critical anesthetic dose is linearly related to the solubility of the drug in the membranes as mentioned in this paper.

Phase Transitions and Critical Phenomena
TL;DR: The field of phase transitions and critical phenomena continues to be active in research, producing a steady stream of interesting and fruitful results as discussed by the authors, and the major aim of this serial is to provide review articles that can serve as standard references for research workers in the field.

The rapid intermixing of cell surface antigens after formation of mouse-human heterokaryons.
L. D. Frye,Michael Edidin +1 more
TL;DR: It appears that the cell surface of heterokaryons is not a rigid structure, but is ‘fluid’ enough to allow free ‘diffusion’ of surface antigens resulting in their intermingling within minutes after the initiation of fusion.

Fluorescence Depolarization Studies of Phase Transitions and Fluidity in Phospholipid Bilayers. 2. Two-Component Phosphatidylcholine Liposomes
TL;DR: The fluorescence deplorarization associated with the hydrophobic fluorescent probe 1,6-diphenyl-1,3,5-hexatriene is used to monitor changes in fluidity accompanying the gel-liquid crystalline phase transition in phosphatidylcholine dispersions, and phase diagrams are interpreted to suggest that the miscibilities of the lipids studied are markedly different in small, single-lamellar vesicles and large multilameLLar lip

Lateral diffusion of rhodopsin in the photoreceptor membrane
Mu-ming Poo,Richard A. Cone +1 more
TL;DR: Rhodopsin undergoes rapid lateral diffusion in the disk membranes of isolated frog and mudpuppy rods, which indicates the disk membrane is highly fluid with a viscosity of ∼1P.
