University of California - Santa Barbara Using the surface forces apparatus and an atomic force microscope, researchers at UC Santa Barbara have taken a molecular approach to myelin membrane interactions, leading to insights into demyelinating diseases, such as multiple sclerosis. Their research is published in the Proceedings of the National Academy of the Sciences. For a healthy nervous system, axons — the long projections of our nerve cells that run throughout our bodies — must...

Biomimetic Membranes on Graphene Open up Novel Applications in Biotechnology – Publication in “Nature Communications“ Researchers around Dr. Michael Hirtz from Karlsruhe Institute of Technology and Dr. Aravind Vijayaraghavan from the University of Manchester have developed a new method to produce artificial membranes: Using a nanoscaled tip, they write tailored patches of phospholipid membrane onto a graphene substrate. The resulting biomimetic membranes, i.e. membranes simulating...

The accumulation of α-synuclein, a small, negatively charged protein, in neural cells, is one of the hallmarks of Parkinson's disease. It has been suggested that oligomeric α-synuclein causes membranes to become permeable, or to form channels on the outer cell membrane. Now, a group of scientists from Sweden has found a way to reliably replicate α-synuclein aggregation on cell membranes to investigate how different forms of α-synuclein...

By Anglin, Timothy C Conboy, John C ABSTRACT The dependence of 1,2-dipalmitoyl-sn-glycero-3- phosphocholine (DPPC) flip-flop kinetics on the lateral membrane pressure in a phospholipid bilayer was investigated by sum- frequency vibrational spectroscopy. Planar-supported lipid bilayers were prepared on fused silica supports using the Langmuir-Blodgett/ Langmuir-Schaeffer technique, which allows precise control over the lateral surface pressure and packing density of the membrane. The lipid...

By Hodzic, Aden Rappolt, Michael; Amenitsch, Heinz; Laggner, Peter; Pabst, Georg ABSTRACT We have studied the concentration and temperature dependent influence of cholesterol, stigmasterol, and sitosterol on the global structure and the bending fluctuations of fluid dimyristoyl phosphatidylcholine and palmitoyl oleoyl phosphatidylcholine bilayers applying small-angle x-ray scattering, as well as dilatometry and ultrasound velocimetry. Independent of the lipid matrix, cholesterol was found...

CHAMPAIGN, Ill. -  Phospholipid bilayers serve as the framework in biological membranes in which other components are embedded. Fundamental not only in biology, lipid bilayers are also essential in applications such as biosensors and nanoreactors. Forming a fluid film like the skin of a soap bubble, lipid molecules are free to move around the membrane laterally -- like couples on a dance floor. At the same time, however, cellular proteins have to interact in a very controlled fashion...

  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
