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...

...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. Conn, a Johns Hopkins graduate with more tha...
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

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...
