Curcumin, turmeric's main ingredient, inserts itself into cell membranes and makes them more orderly and resistant to infection, U.S. researchers said. University of Michigan researchers led by Ayyalusamy Ramamoorthy said the membrane goes from being crazy and floppy to being more disciplined and ordered, so information flow through it can be controlled. Probing high-resolution intermolecular interactions in the messy membrane environment has been a major challenge to commonly-used...

A more specific and faster detection of viruses has been identified in new research by Trinity College Dublin's Professor of Physics, Martin Hegner at Trinity College's Center of Research on Adaptive Nanostructures and Nanodevices (CRANN) and an international team of researchers. These findings have been published online in Nature News and will be published in the international peer-reviewed journal Nature Nanotechnology in March. Viruses can be now detected in fluids and their detection is...

US-based biotechnology company Integral Molecular has initiated a federally-funded program to discover new drugs to combat influenza infection. Sponsored by the National Institute of Allergy and Infectious Diseases, Integral Molecular's R&D program will utilize its proprietary Lipoparticle technology to discover new ways of inhibiting M2, a critical viral ion channel. The M2 ion channel is said to be a validated drug target for all strains of influenza, including the H5N1 pandemic...

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...

HOUSTON -- It's well known that high doses of aspirin can cause ulcers and temporary deafness, but the biochemical mechanism responsible for these phenomena has never been deciphered. New research from Rice University offers clues, showing for the first time how salicylate -- an active metabolite of aspirin -- weakens lipid membranes. Researchers believe these mechanical changes disrupt the lining of the stomach, which functions to protect underlying tissue from the acidic contents of...

HOUSTON  "“ A protein that provides a vital passage through a bacterium's outer cell wall will misfold and malfunction if that wall is built of the 'wrong' material, scientists at The University of Texas Medical School at Houston report in a finding that has long-term implications for understanding diseases caused by misfolded proteins such as cystic fibrosis, Alzheimer's disease, and mad cow disease. The paper in today's Journal of Biological Chemistry by Professor of...

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...


Word of the Day
cruet
  • A vial or small glass bottle, especially one for holding vinegar, oil, etc.; a caster for liquids.
