Primitive Artificial Cells Turned Into Complex Biological Materials
2014-02-04 15:22:51

University of Southern Denmark It is a big dream in science: To start from scratch with simple artificial microscopic building blocks and end up with something much more complex: living systems, novel computers or every-day materials. For decades scientists have pursued the dream of creating artificial building blocks that can self-assemble in large numbers and reassemble to take on new tasks or to remedy defects. Now researchers from University of Southern Denmark have taken a step...

WELWYN GARDEN CITY, England and BOSTON, January 8, 2014 /PRNewswire/ -- Heptares Therapeutics, the leading GPCR drug discovery and development company, notes that its President, Dan Grau, will moderate a panel discussion entitled "Global Entrepreneurs: Biotech Building Beyond Borders" (1:30-2:00pm Eastern time on 11 January) at the Boston Biotech East/West CEO Conference [http://bbbiotechconference.com/conference-agenda.php?id=14 ], which takes place at the Four Seasons...

Xray Maps GPCR
2013-12-20 12:57:28

redOrbit Staff & Wire Reports - Your Universe Online Researchers have used one of the brightest X-ray sources in the world to map the three-dimensional structure of an important cellular gatekeeper known as a G protein-coupled receptor, or GPCR, in a more natural state than has been previously possible. The new technique, described Friday in the journal Science, is a major leap forward in exploring GPCRs, a vast, hard-to-study family of proteins that plays a key role in human health...

Innovation could lead to faster drug therapies and increased understanding of proteins on the microscopic level Membrane proteins are the “gatekeepers” that allow information and molecules to pass into and out of a cell. Until recently, the microscopic study of these complex proteins has been restricted due to limitations of “force microscopes” that are available to researchers and the one-dimensional results these microscopes reveal. Now, researchers at the University of Missouri...

Research will be presented on Sunday, Dec. 15, during ASCB annual meeting in New Orleans Resolving a fundamental question in cell biology and showing off the powers of new high-resolution 3-D imaging, NIH scientists have discovered where the Golgi apparatus, which sorts newly synthesized proteins for transport inside and outside the cell, goes when it disassembles during cell division, according to research to be presented on Sunday, Dec. 15, at the American Association for Cell Biology...

Intracellular ABC Transporters Allow Leaf Beetle Larvae To Accumulate Defensive Substances When Feeding
2013-12-09 11:58:38

Max Planck Institute for Chemical Ecology Similar membrane proteins play a crucial role in the transport of toxic substances out of the cell Scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, have discovered the decisive biological stimulator for the accumulation of defensive substances in leaf beetle larvae used by the insects to fend off predators: ABC transport proteins, which are found in large quantities in glandular cells of the larvae. The poplar leaf...

How Membrane Transporter Moves
2013-12-03 09:50:42

University of Illinois Researchers have tried for decades to understand the undulations and gyrations that allow transport proteins to shuttle molecules from one side of a cell membrane to the other. Now scientists report that they have found a way to penetrate the mystery. They have worked out every step in the molecular dance that enables one such transporter to do its job. The new findings, reported in the Proceedings of the National Academy of Sciences, will help scientists figure...

Scientists have described a new family of proteins that appear to play a key role in cancer and might be targets for future cancer drugs. A major new study in the journal Nature sets out the structure of the new family, called glutamate intramembrane proteases – the founding member of which plays a critical role in transforming healthy cells into cancer cells. The research, funded by Cancer Research UK and conducted by scientists at The Institute of Cancer Research, London, defined...

Researchers from the University of Southampton, in collaboration with researchers at the University of Quebec at Montreal, have developed a new microsystem for more efficient testing of pharmaceutical drugs to treat diseases such as cystic fibrosis, MG (myasthenia gravis) and epilepsy. A large percentage of pharmaceutical drugs target ion channels, which are proteins found in a cell's membrane, that play a pivotal role in these serious disorders and that are used to test the effectiveness...

Esophagus
2013-04-30 13:37:01

The esophagus is the muscular tube that is located between the pharynx and the stomach that aids in digestion during swallowing. Formation and Orientation The esophagus is composed of four separate layers; the mucosa, submucosa, muscularis externa and the adventitia. The mucosa includes the stratified squamous epithelium, lamina propria and muscularis mucosae. The submucosa houses the esophageal glands and connective papillae. The muscularis externa is composed of three sublayers The...

Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
