Computerized atlas highlights 'plethora' of changes in brain disorder
...hem to more precisely link alterations in specific structures
to changes in cognitive functions. Although interventions to alter brain development in Williams syndrome are likely still a long way off, identifying the connections between genetic changes, alterations in brain structure and changes in brain funct...
New MRI technique shows emphysema in asymptomatic smokers
... helium, the researchers were able to measure lung structures
with 2 times more precision than with CT, and 10 times more precision than with conventional MRI methods. Age is a significant factor in the development of emphysema-like changes. The researchers found that, in general, the airspaces in the lungs enl...
Pick your COX partners
...ion, and heart attacks are formed. The molecular structures
of COX-1 and COX-2 are remarkably similar, but a subtle variation in their structure permits the construction of drugs that are selective in their inhibition for COX -2. For this study the researchers developed a novel genetic mouse model that mimics...
EU's free trade rules exacerbate alcohol-related harm

undermine national alcohol-control policies and contribute to social harm. The Lancet comments: "The two central tenets of alcohol policy currently favoured by the EU's politicians--public education and self regulation by the alcoholic-beverage indus...

DNA repair in mammal embryos is a matter of timing
..." McKinnon said. But as cells acquire specialized structures
and functions, they stop dividing and no longer produce sister chromatids. "When cells begin assuming specific roles in the brain, they stow away most of their chromosomes into tightly wrapped strings of DNA and use only those genes required to survi...
$20 million gift to Rush University Medical Center kicks-off campus redevelopment

Cancer-causing protein may heal damaged spinal cord and brain cells
... of Id proteins to stimulate growth of axons - the structures
on neurons responsible for transmitting electrical signals in the brain and spinal cord. But to do that they needed to overcome the problem of the APC enzyme, which degrades the protein in normal cells. So they constructed a "super" Id protein that...
