First-of-its-kind wearable low vision aid helps visually impaired

"Even with a cane or a guide dog, low-vision people can have a difficult time identifying obstacles that can be hazardous," said Eric Seibel, research assistant professor in mechanical engineering at the lab, who for the past four years has overseen the student team that developed the device. "This is another set of eyes looking out for them."

New technology gives neurosurgeons real-time images in the operating room

Within the past decade, imaging systems have provided much clearer pictures of the brain’s structures, and navigational tools have helped physicians map direct approaches, minimize points of entry and spare healthy brain and function.

30-ton superconducting magnet to further brain research

The 30-ton, superconducting magnet that forms the center of a 7-Tesla MRI (magnetic resonance imaging) system developed by Siemens Medical Solutions will be uncrated and moved by crane from a truck into the New York University School of Medicine’s Center for Biomedical Imaging this Friday morning.

New technology to measure the sensitivity of nerve fibers that wire up the brain during development

Researchers at Georgetown University have developed a novel technology to precisely measure the sensitivity of nerve fibers that wire up the brain during development. Through use of this technology, they discovered that these fibers, or axons, possess an incredible sensitivity to molecular guidance cues that direct the axon’s route to its desired destination in the brain.

Trial shows Daclizumab therapy improves multiple sclerosis outcome

A small clinical trial of patients with multiple sclerosis (MS) who did not respond to interferon alone found that adding the human antibody daclizumab improved patient outcome. Patients who received the combined therapy had a 78 percent reduction in new brain lesions and a 70 percent reduction in total lesions, along with other significant clinical improvements.

Diabetes drug improves metabolic changes associated with HIV combination therapy

Use of an oral antidiabetes medication produced significant improvement in a group of patients with HIV lipodsytrophy, a syndrome involving the redistribution of fat and other metabolic changes in those receiving combination drug therapy for HIV infection.

Protein that appears to play a key role in Alzheimer's disease

A protein that allows human cancer to resist multiple anticancer drugs also appears to play a key role in Alzheimer's disease, according to research conducted at Fox Chase Cancer Center. The protein, active in brain tissue, could be a target for new drugs to treat patients with Alzheimer's.

About one in 35 adult Americans is at high risk of coronary heart disease

About one in 35 adult Americans is at high risk of coronary heart disease, meaning they have a greater than 20 percent chance of developing heart disease within 10 years, and about one in six has a 10-year risk that is greater than 10 percent, according to a new study in the May 19, 2004 issue of the Journal of the American College of Cardiology.

Multimillion-dollar electron microscope unveils shapes of viruses and proteins

With a multimillion-dollar electron microscope and computer programs that can pick out the shapes of structures only six atoms wide, Dr. Wah Chiu and his colleagues at Baylor College of Medicine in Houston are attempting to explain the intricate structures of viruses and proteins.

New generation of programmable chips set to revolutionise medical industry

The MI-3 project is focussing on developing and exploiting a new generation of programmable chips that will produce images that can be transformed even before they leave the camera. Active Pixel Sensors exploit the capabilities of Complimentary Metal Oxide Semi-Conductor (CMOS) Chips by allowing intelligent imaging that can focus right down to individual pixels.

Study helps to visualize how brain develops with age

The brain's center of reasoning and problem solving is among the last to mature, a new study graphically reveals. The decade-long magnetic resonance imaging (MRI) study of normal brain development, from ages 4 to 21, by researchers at NIH's National Institute of Mental Health (NIMH) and University of California Los Angeles (UCLA) shows that such "higher-order" brain centers, such as the prefrontal cortex, don't fully develop until young adulthood.

Interventional radiologists now are able to treat using minimally invasive procedures

Interventional radiologists at Temple University Hospital now are able to treat many patients with minimally invasive procedures not available only a few years ago. “Conditions that used to require extensive surgery now take an hour or less, and patients leave with a bandaid and walk home,” says Gary Cohen, M.D., Section Chief of Interventional Radiology and Vice Chairman of Radiology. “How can you beat that?”

Technique to visualize changes in nerve connections when flies learn may help to understand how memories form

For the first time, researchers have used a technique called optical imaging to visualize changes in nerve connections when flies learn. These changes may be the beginning of a complex chain of events that leads to formation of lasting memories.
