For the first time, UCLA researchers have discovered that people with sleep apnea show tissue loss in brain regions that help store memory. Reported in the June 27 edition of the journal Neuroscience Letters, the findings emphasize the importance of early detection of the disorder, which afflicts an estimated 20 million Americans.
Scientists have discovered that three-month-old infants are sensitive to emotional signals that refer to objects in the world. It was once thought that young infants could only process social signals that were directed at them. However, in a new study published in PLoS ONE, researchers from Hunter College and the Max Planck Institute for Human Cognitive and Brain Scientists show that three-month-old infants go beyond face-to-face social interactions: they even use social cues to process objects in the world around them.
COLUMBUS, Ohio Viruses genetically designed to kill cancer cells offer a promising strategy for treating incurable brain tumors such as glioblastoma, but the body's natural defenses often eliminate the viruses before they can eliminate the tumor.
The findings of an animal study by researchers at the Ohio State University Comprehensive Cancer Center help explain why this happens and could improve this therapy for brain cancer patients.
Technology can send a man to the moon, help unlock the secrets of DNA and let people around the world easily communicate through the Internet. But can it substitute for nature?
The use of daytime bright lighting to improve the circadian rhythm of elderly persons was associated with modest improvement in symptoms of dementia, and the addition of the use of melatonin resulted in improved sleep, according to a study in the June 11 issue of JAMA.
A short-term, very-high dose regimen of the immune-suppressing drug cyclophosphamide seems to slow progression of multiple sclerosis (MS) in most of a small group of patients studied and may even restore neurological function lost to the disease, Johns Hopkins researchers report. The findings in nine people, most of whom had failed all other treatments, suggest new ways to treat a disease that tends to progress relentlessly.
Researchers at the University of Minnesota have discovered a gene that may provide a clue as to why obesity rates increase with age. The research was published today in the Proceedings of the National Academy of Sciences.
AUSTIN, Texas A detergent solution developed at The University of Texas at Austin that treats donor nerve grafts to circumvent an immune rejection response has been used to create acellular nerve grafts now used successfully in hospitals around the country. Research also shows early promise of the detergent solution having possible applications in spinal cord repair.
Champaign, IL June 10, 2008 Various intervention strategies have been implemented to curb the rise of HIV, and a factor that might affect exposure to interventionsis gender. A new study in the Journal of Applied Social Psychology reviewed the behavior of participants exposed to various HIV brochures. Researchers found that both men and women were likely to avoid gender-mismatched brochures. Women, however, were more likely to approach gender-matched brochures over gender-neutral brochures.
