Short range ballistic motion in fluid lipid bilayers studied by quasi-elastic neutron scattering
Diffusion is the primary mechanism for movement of lipids and proteins in the lateral direction of a biological membrane. In this paper we have used quasi-elastic neutron scattering to examine theExpand
The Observation of Highly Ordered Domains in Membranes with Cholesterol
Rafts, or functional domains, are transient nano- or mesoscopic structures in the exoplasmic leaflet of the plasma membrane, and are thought to be essential for many cellular processes. Using neutronExpand
Cholesterol expels ibuprofen from the hydrophobic membrane core and stabilizes lamellar phases in lipid membranes containing ibuprofen.
There is increasing evidence that common drugs, such as aspirin and ibuprofen, interact with lipid membranes. Ibuprofen is one of the most common over the counter drugs in the world, and is used forExpand
Partitioning of ethanol into lipid membranes and its effect on fluidity and permeability as seen by X-ray and neutron scattering
We present a combined neutron and X-ray scattering investigation to study the effect of ethanol on the molecular structure and dynamics of lipid membranes.Expand
The production of fibers and films from solubilized hagfish slime thread proteins.
Hagfish slime threads, which make up the fibrous component of the defensive slime of hagfishes, consist primarily of proteins from the intermediate filament family of proteins and possess impressiveExpand
Nanosecond lipid dynamics in membranes containing cholesterol.
Lipid dynamics in the cholesterol-rich (40 mol%) liquid-ordered (lo) phase of dimyristoylphosphatidylcholine membranes were studied using neutron spin-echo and neutron backscattering. RecentExpand
Structure of Cholesterol in Lipid Rafts.
Rafts, or functional domains, are transient nano-or mesoscopic structures in the plasma membrane and are thought to be essential for many cellular processes such as signal transduction, adhesion,Expand
Effect of cholesterol on the lateral nanoscale dynamics of fluid membranes
Inelastic neutron scattering was used to study the effect of 5 and 40 mol% cholesterol on the lateral nanoscale dynamics of phospholipid membranes. By measuring the excitation spectrum at severalExpand
Co-existence of gel and fluid lipid domains in single-component phospholipid membranes
Lateral nanostructures in membranes, so-called rafts, are believed to strongly influence membrane properties and functions. The experimental observation of rafts has proven difficult as they areExpand
Diffusion in single supported lipid bilayers studied by quasi-elastic neutron scattering
It seems to be increasingly accepted that the diversity and composition of lipids play an important role in the function of biological membranes. A prime example of this is the case of lipid rafts;Expand
