For the first time, researchers at Karolinska Institutet in Sweden have managed to obtain detailed images of the way in which the transport protein GLUT transports sugars into cells. Since tumors are highly dependent on the transportation of nutrients in order to be able to grow rapidly, the researchers are hoping that the study published in the scientific magazine Nature Structural & Molecular Biology will form the basis for new strategies to fight cancer cells. In order to be able to...

A three-dimensional image of one of the proteins that serves as an on-off switch as it binds to receptors on the surface of a cell suggests there may be a sort of main power switch that could be tripped. These surface receptors are responsible for helping cells discern light, set the heart racing, or detect pain. The finding, published online April 21, 2013, in the journal Nature by a research collaboration involving this year's Nobel laureates in chemistry, could help in the development...

Lawrence Berkeley National Laboratory Your cells are social butterflies. They constantly interact with their surroundings, taking in cues on when to divide and where to anchor themselves, among other critical tasks. This networking is driven in part by proteins called integrin, which reside in a cell´s outer plasma membrane. Their job is to convert mechanical forces from outside the cell into internal chemical signals that tell the cell what to do. That is, when they work properly....

A team including scientists from The Scripps Research Institute (TSRI), the University of North Carolina at Chapel Hill and the Chinese Academy of Sciences has determined and analyzed the high-resolution atomic structures of two kinds of human serotonin receptor. The new findings help explain why some drugs that interact with these receptors have had unexpectedly complex and sometimes harmful effects. "Understanding the structure-function of these receptors allows us to discover new...

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...

monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
