Cell stress protein linked to aggressive breast cancer
... breast cells as three-dimensional (3D) gland-like structures
that are similar to those present in the normal breast. However, when the researchers introduced alphaB-crystallin into non-cancerous breast cells, the cells started growing uncontrollably and formed enlarged 3D masses that resemble breast tumors. T...
UCSD team creates model for genetic brain syndrome
...eeson. "The human brain is one of the most complex structures
we know of, and evolution has been working hard to make the human brain over the past million years. It is not surprising that the human brain is more susceptible to genetic variation than the brain of a laboratory mouse."...
MRIs better at diagnosing needs for 'bionic ear' implants
...re also working on techniques to alter the surface structures
of cochlear implants at the nano level to keep these biofilms from forming," Dr. Roland said. Other UT Southwestern researchers involved in the study included Drs. Timothy Booth, associate professor of radiology, and David Parry, a former resident....
Potential treatment for intracerebral hemorrhage under study

between brain cells. "It can disrupt huge bundles of fibers that carry information," says Dr. Hall. "Modern neuroimaging shows it also seems to have an effect more distant than just where you see the hemorrhage." Patients can experience one-sided par...
Gene therapy 'turns off' mutation linked to Parkinson's disease
...arkinson's disease. Alpha-synuclein is abundant in structures
known as Lewy bodies a diagnostic hallmark of Parkinson's disease. Research has shown that mutant forms of the alpha-synuclein gene, as well as too much alpha- synuclein protein, are involved in the development Parkinson's disease in some families....

that favor exercise in neighborhoods influence the physical activity levels of children between five and 17 years of age. "The built environment, how we design our cities and neighborhoods, seemed to help," said Bhat, who holds the Fluor Centennial T...
For some, aspirin doesn't increase risk of recurring hemorrhagic stroke

Brain researchers discover the evolutionary traces of grammar
Researchers found that simple language structures
are processed in an area that is phylogenetically older, and which apes also possess. Complicated structures, by contrast, activate processes in a comparatively younger area which only exists in a more highly evolved species: humans. These results ar...
