The small device does not need extra oxygen, it works with normal air. Joe Potkay, a research assistant professor in electrical engineering and computer science published the technique this week in the journal Lab on a Chip. The scientists developed this prototype while keeping track of the natural design of our lungs. It is made of breathable silicone rubber acting as blood vessels that get as small as one-fourth of the width of a human hair. Because it works on the same scale as normal lung tissue, the team was able to shrink the distances for gas diffusion compared to current techniques. Tests usin...

The method uses functional MRI (fMRI) and diffusion tensor magnetic resonance imaging (DTI) to scan the brain, and data crunching software to interpret the data. The researchers hope that the finding will help parents and therapists uniquely identify which learning tools are best for each child. From the announcement by Vanderbilt University : The 45 children who took part in the study ranged in age from 11 to 14 years old. Each child first took a battery of tests to determine their reading abilities. Based on these tests, the researchers classified 25 children as having dyslexia, which means that they exhibited significant difficulty le...

In a study by Bulakbasi et al, AJNR 27: 1983-86, transient lesion of splenium of corpus callosum (SCC) is a significant but nonspecific finding. It is probably due to inflammatory changes of the splenium and may be only detectable change in patients with good prognosis, indicating a clinically mild form of encephalitis/encephalopathy. Clinically all patients recover on days 4-9.From Sumer's Radiology Site http://www.sumerdoc.blogspot.com -The Top Radiology Magazine.

The styles range from sport wheelchairs, for activities like racing or basketball, to the new all terrain wheelchairs, or to everyday use wheelchairs. Styles include choices from customized super lightweight titanium, such as the Trilite, to heavier chairs, that still might only weight 30 pounds or less. Getting the wheelchair in and out of the car can be done by a variety of manual techniques (in which case a lighter one is better), or by using a wheelchair lift. At youtube.com if you search for "wheelchairs,""wheelchair lifting" and "wheelchair lift to vehicle" you can get some ideas that will help from the videos.

A significant reduction in FA was observed in the rostrum of the CC in patients with OCD compared with the rostral FA in the control subjects. (FA-Fractional anisotropy). Study results support the widely held view that the orbital prefrontal region is involved in the pathophysiology of OCD and indicate that the orbitofrontal circuit influences symptom severity in patients with OCD.

Lindner Center for Autism, North Shore-Long Island Jewish Health System in Bethpage, N.Y. found that there were increased areas of gray matter in the brains of children with autism.Using a new imaging technique researchers found autistic children had increased gray matter in the parietal lobes which has previously been implicated in the mirror neuron system. Mirror neurons are brain cells that are active when an individual is performing and action and experiencing an emotion or sensation and when the person witnesses the same actions, emotions and sensations in others. This system allows humans to learn by seeing as well as by doing.The study consisted of 13 male patients with high-functioning autism or Asperger syndrome with an IQ over 70 and 1...
