Researchers use MRI to predict recovery after spinal cord injury

...4 to 48 hours of injury. The research team studied three measurable imaging parameters: maximum spinal cord compression (MSCC), maximum canal compromise (MCC) and length of lesion (LOL). They also looked at other factors, including bleeding within the spine, swelling and soft tissue injury. The results ...

Focused ultrasound relieves fibroid symptoms in women

... The findings showed significant symptom relief at three months and sustained relief at one year. Women treated with the optimized protocol reported greater symptom relief and quality of life improvement than those treated with the original protocol. No serious adverse effects were reported. "We have sh...

Detecting cold, feeling pain: Study reveals why menthol feels fresh

...physical mechanisms that account for this"" All three receptors the Julius lab has discovered are members of the TRP family of ion channels expressed on sensory neurons. The latest finding adds to the evidence, says Julius, that TRP channels are the principal transducers of thermal stimuli in the mammal...

Human stem cell treatment restores motor function in paralyzed rats

...d with hSSCs returned to walking at six weeks, and three others had improved mobility in all lower extremity joints. All nine animals grafted with hSSCs achieved significantly better motor scores than those in the control group, and showed a consistent presence of transplanted cells in the spinal area. In...

pHLIP, a novel technology to locate and treat tumors

...nd treating tumors.? The pHLIP molecule has three states: soluble in water, bound to the surface of a membrane, and inserted across the membrane as an alpha-helix. Under normal tissue conditions of neutral pH, the water-soluble form is favored. At acidic pH, the transmembrane alpha-helix predominate...

They decided to include four different note durations with codons that appear more frequently transcribed into longer notes than those which appear less often. Individual amino acids are expressed ...

US control strategies may make flu epidemics worse, UCLA study shows

Alien plants attack using 'resource conservation' as weapon, researchers say

...f alien and native plants, the researchers studied three ecosystems in Hawaii-a forested area with limited light, volcanic soils with low nutrients and a desert. They compared 19 invaders with 19 closely related indigenous plants-for example, an invasive raspberry versus a native raspberry. Using an electr...

Traumas like Sept. 11 make brains more reactive to fear

... Specifically, the Cornell researchers found that three years after Sept. 11, 2001, the amygdalae were most sensitive in those who were close to the World Trade Center. These individuals tended to still experience lingering symptoms that were not severe enough to be diagnosed as a mental disorder. Those w...
