Children can benefit from surgery for sleep apnea

Times have changed. Within the last ten years, the primary reason that children have had surgery to remove their tonsils and adenoids is not because of infection. Instead, up to 90 percent of the adenotonsillectomy surgeries are to correct obstructive sleep apnea (OSA).

Middle-aged women who take an active role in their health care may be less likely to develop cardiovascular disease

The results, presented today at the American Psychosomatic Society Annual Meeting, suggest women who believe they should take charge of their health, rather than rely solely on treatment by doctors, have fewer signs of pre-clinical atherosclerosis.

Virologists make major step towards understanding the process of HIV infection

A working group of virologists headed by Professor Hans-Georg Kräusslich at Heidelberg University Hospitals, jointly with Professor Hanswalter Zentgraf, Division of Applied Tumor Virology of the Deutsches Krebsforschungszentrum (German Cancer Research Center, DKFZ), have been the first to label Human Immunodeficiency Viruses (HIV) for visual investigations without inhibiting the functional characteristics of the virus.

$Women who need treatment for osteoporosis may not be receiving it because their history of fractures not being considered$

Women who need treatment for osteoporosis may not be receiving it because their history of fractures not being considered

Previous fractures indicate that bones are weaker than normal, but the information isn't being taken into account when treating for osteoporosis, said Dr. Kerry Siminoski, professor of radiology and diagnostic imaging at the University of Alberta.

Early Alzheimer's disease may be precipitated by a neuron traffic jam

Early Alzheimer's disease may be precipitated by a “traffic jam” within neurons that causes swelling and prevents proper transport of proteins and structures in the cells, according to new studies by Howard Hughes Medical Institute researchers.

New imaging technology may serve as objective outcome measures for orthopedic conditions

New imaging technologies are enabling doctors to not only diagnose a variety of orthopaedic and musculoskeletal conditions with more accuracy, but also to determine with unprecedented precision whether clinical recovery from bone, joint or tendon damage is actually complete and not simply a "placebo effect."

New imaging method that may provide a clearer diagnosis of breast cancer

"This technique involves a new method for interpreting information gathered through MRI," explained Springer. "The technique involves recognizing that certain properties of MRI signals can change during the examination, much like the changing of a camera's shutter speed.

Computer imaging and web-based 3D tools help surgeons predict patient outcomes

People are as different on the inside as they are on the outside, making it difficult to predict how an individual will respond to a surgical intervention without resorting to statistics and educated guesses.

Better ways to heal and regenerate bones using microcomputed tomography imaging

Tissue engineers can choose from a wide range of living cells, biomaterials and proteins to repair a bone defect. But finding the optimum combination requires improved methods for tracking the healing process.

Nonsurgical microspheres an option for liver cancer patients

A study in February’s Journal of Vascular and Interventional Radiology found that patients undergoing liver cancer treatment with Theraspheres?, radioactive microspheres containing Yittrium-90, can tolerate a 150 Gy single dose or 268 Gy repeated dose without risk of radiation-induced liver disease.

Visual recognition begins with categorization

Take a moment and look at a picture near you. What did you see? How long did it take you to understand what was in the image, meaning how long did it take you to realize the green blob was a tree? Or that the orange circle was a piece of fruit? Most likely you assume that it took you no time at all, you just knew.

Researchers show how attention enhances visual perception

The researchers, from NYU's Department of Psychology and Center for Neural Science, found that attending to, or selectively processing information from a given location without directing our eyes to that location, enhances performance in visual tasks as well as the neural activity underlying the processing of ensuing images. The results are published in the latest issue of the journal Neuron.
