Opioids, such as morphine, are still the most effective class of painkillers, but they come with unwanted side effects and can also be addictive and deadly at high doses. Designing new pain-killing drugs of this type involves testing them on their corresponding receptors, but access to meaningful quantities of these receptors that can work in experimental conditions has always been a limiting factor. Now, an interdisciplinary collaboration between researchers at the University of...

Contaminated Water Cleaned By Solar-powered Nanofilters That Pump In Antibiotics
2013-06-06 20:24:09

American Chemical Society Using the same devious mechanism that enables some bacteria to shrug off powerful antibiotics, scientists have developed solar-powered nanofilters that remove antibiotics from the water in lakes and rivers twice as efficiently as the best existing technology. Their report appears in ACS´ journal NanoLetters. David Wendell and Vikram Kapoor explain that antibiotics from toilets and other sources find their way into lakes and rivers, with traces appearing in...

NIH-funded study reveals protein, fatty molecules and cellular energy work together during endocytosis Cells ingest proteins and engulf bacteria by a gymnastic, shape-shifting process called endocytosis. Researchers at the National Institutes of Health revealed how a key protein, dynamin, drives the action. Endocytosis lets cells absorb nutrients, import growth factors, prevent infections and accomplish many other vital tasks. Yet, despite decades of research, scientists don't fully...

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...

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...
