Nasal spray of oxytocin improves brain function in children with autism
A single dose of the hormone oxytocin, delivered via nasal spray, has been shown to enhance brain activity while processing social information in children with autism spectrum disorders.

Meditation may help brain to recover from diseases
Brain imaging study reveals that experienced meditators seem to be able switch off areas of the brain associated with daydreaming as well as psychiatric disorders such as autism and schizophrenia.

Door-to-balloon time is 90 min in 91% of heart attack patients in US
The period from hospital arrival to angioplasty is called "door-to-balloon" time (D2B). A new study showed that 91 percent of patients were treated in a D2B time of less than 90 minutes in 2010, compared with 44 percent in 2005.

Autism linked to hundreds of genetic changes
Investigating 1,000 families reveals hundreds of small genetic variations are associated with autism spectrum disorders, according to a multi-site collaborative study led by researchers at Yale University. These genetic findings can be used to begin unraveling the underlying biology of autism.

Ghrelin can slow Parkinson's disease
Stomach hormone - Ghrelin - may be used to boost resistance to, or slow, the development of Parkinson's disease, Yale School of Medicine researchers report in a study published in the Journal of Neuroscience.

CDC guidelines for seasonal and swine flu vaccines questioned
With the seasonal flu season approaching and uncertainty over whether swine flu will become more severe, new research published by Yale School of Public Health has found that more people are likely to avoid illness if vaccines are given out first to those most likely to transmit viruses, rather than to those at highest risk for complications.

Brain senses fatty food
In the battle against obesity, Yale University researchers may have discovered a new weapon - a naturally occurring molecule secreted by the gut that makes rats and mice less hungry after fatty meals.

Genes, lower reward response linked to weight gain, obesity
The brains of obese people seem to respond to a tasty treat with less vigor than the brains of their leaner peers, suggesting obese people may overeat to compensate for a reduced reward response, according to a new brain imaging and genetics study conducted by researchers at Yale University, The John B. Pierce Laboratory, the University of Texas and Oregon Research Institute.

Stomach bacteria protect against type 1 diabetes
In a dramatic illustration of the potential for microbes to prevent disease, researchers at Yale University and the University of Chicago showed that mice exposed to common stomach bacteria were protected against the development of Type I diabetes.

Gene protects newborns from respiratory distress syndrome
Yale School of Medicine researchers have isolated a gene that helps protect newborns from the most common respiratory cause of infant death in the United States - respiratory distress syndrome.

Early treatment stops epilepsy seizures
It is possible to suppress the development of epilepsy in genetically predisposed animals revealed by Yale School of Medicine researchers. This new study would open the door to treating epilepsy as a preventable disease.

Gene changes may lead to hardening of arteries, atherosclerosis
Researchers revealed that changes in gene may lead to hardening of the arteries and expands lesions in the aorta and promotes coronary atherosclerosis. The study was done by researchers from Yale School of Medicine and published in Cell Metabolism.

Colon cancer screenings could pose harm to some
Even though current guidelines advocate colorectal cancer screenings for those with severe illnesses, they may bring little benefit and may actually pose harm, according to a recent study by Yale School of Medicine researchers published in the Archives of Internal Medicine.

Exercise gene could help with depression
Boosting an exercise-related gene in the brain works as a powerful anti-depressant in mice - a finding that could lead to a new anti-depressant drug target, according to a Yale School of Medicine report in Nature Medicine.
