Fifteen-year hunt uncovers gene behind 'pseudothalidomide' syndrome

...ve them together, ensuring that the two copies are lined up together at the center of the dividing cell. Once lined up, tiny molecular "motors" attach to the centromere of each copy and pull the original and the new ...

Nanoparticles carry cancer-killing drugs into tumor cells

...eter, which means it would take 100,000 nanometers lined up side-by-side to equal the diameter of a human hair. Dendrimers have a tree-like structure with many branches where scientists can attach a variety of molecules, including drugs. In experiments reported in Cancer Research, U-M scientists attached m...

Students revamp tractor for use by workers with disabilities

...inue their studies in graduate school. Wolcott has lined up a job with a private consulting firm. The modified tractor was one of nine Johns Hopkins projects completed this year by undergraduates in the engineering design course. The class is taught by Andrew F.

4D proton therapy, radiation-resistant tumors, interpreting medical images

...r: an image is formed when paramagnetic molecules, lined up in a magnetic field, absorb and then re-emit electromagnetic waves in or near the microwave portion of the spectrum. Using a series of magnetic fields that vary in strength over a given region of space, these emissions can be reconstructed into a...

Gaps in intestinal barrier could cause Crohn's disease

...hat the process leaves behind. The human bowel is lined with millions of projections called villi which increase the surface area of the intestine to allow for the efficient absorption of nutrients. The villi are covered in epithelial cells which are constantly renewed around a thousand billion cells are...

Cannabis smoke is less likely to cause cancer than tobacco smoke

...he cells of lungs and the respiratory passages are lined with nicotine receptors, but do not appear to carry THC receptors. This explains why cannabis smoking has not been associated with lung cancer, a main cause of death from cigarette smoking. Cannabis has also been shown to kill cancer cells and to re...

Mayo Clinic discovers two key players in cancer prevention and how they work

...parate in the wrong way. Then they aren't properly lined up for the next step in the choreography of healthy cell division. The result of being in the wrong place at the wrong time is that they can't connect with the next partner; a healthy cell process is undermined; chromosomes are not correctly distribu...

Study reveals new player in sepsis-associated acute respiratory distress syndrome

...of the blood vessels? Blood vessels are normally lined with tightly linked cells, called endothelial cells, that form an impermeable barrier. Animal experiments had suggested that the development of this barrier is controlled by two small proteins called angiopoietin-1 (Ang-1) and angoipoietin-2 (Ang-2) ...

Robot assisted surgery more accurate than conventional surgery

...t, the replacement knee parts were more accurately lined up than in conventional surgery. All of the robotically assisted operations lined up the bones to within two degrees of the planned position, but only 40 percent of the conventionall...

Children's emotional distress after hurricane linked with parents' stress levels

...s remained unrepaired and large debris piles still lined the streets. "Our study found about 100 children with high levels of post traumatic stress in one rural county, eight months after Hurricane Charley. Because the study was anonymous, we don't know whether any of these children were treated for their...

Master planners in brain may coordinate other areas' roles in cognitive tasks

...ompletion of different tasks. They just have to be lined up to play their part when their abilities are needed. Other neuroscientists previously have implicated the cingulate in a variety of specialized cognitive tasks, Dosenbach notes, but the new analysis may change their thinking. "It's a question of wh...

...t molecules. "A crystal is like toy soldiers all lined up marching together," Ediger says. "A glass is a teenager's room, with stuff packed in everywhere." Just as levels of messiness can range from cluttered to chaotic, levels of molecular disorder can vary between different types of glass. Glasses co...

Study finds unexpected results in acid suppression between two OTC heartburn treatments

...at a cellular level in the stomach. The stomach is lined with millions of acid producing pumps. Acid producing pumps rely on three chemical signals that tell them to produce stomach acid. H2RAs are able to block one of these signals, thereby reducing the amount of acid produced and generally have a quicker...
