Researchers see individual differences in brain activation depending on person's preferences or aversions to risk

Distinct regions of the human brain are activated when people are faced with ambiguous choices versus choices involving only risk, Duke University Medical Center researchers have discovered.

New molecular target for potential drugs to treat acute respiratory distress syndrome

Researchers at the University of Virginia Health System have identified a molecular target, or receptor, for potential drugs to treat acute respiratory distress syndrome (ARDS), a sudden and life-threatening failure of the lung.

Common cardiac sodium channel variant associated with sudden infant death in African Americans

Steve A.N. Goldstein and colleagues from the Pritzker School of Medicine in Chicago have found that a specific mutation, called S1103Y, in a heart protein known as SCN5A is associated with a dramatic, 24-fold increased risk of sudden infant death syndrome (SIDS) in African American infants.

Can marriages be saved by treating snoring?

The husband snores. The wife nudges him to flip over. Both wake up feeling grouchy the next morning. It's a common occurrence that may have more of an impact on the marriage than most couples think.

Acetazolamide improves central sleep apnea in heart failure

Since sleep apnea is associated with heart failure, patients who take a single dose of acetazolamide - a mild diuretic and respiratory stimulant - before going to bed exhibit less sleep apnea, improved blood oxygen levels and fewer daytime symptoms of sleepiness.

Electrical microstimulation allows researchers to map the brain for the first time

Over the last two centuries electrical microstimulation has been often used to demonstrate causal links between neural activity and specific behaviors or cognitive functions. However, to understand the mechanisms by which electrical microstimulation can cause alternations in behaviors and cognitive functions it is imperative to characterize the cortical activity patterns that are elicited by stimulation locally around the electrode and in other functionally connected areas.

Online patient monitoring

Drivers know whether or not their cars are running properly by observing the dashboard. Physicians can check vital parameters such as the pulse even when their patients are at home. The data can be recorded with the wireless monitoring device VitaSENS.

Surprising autism finding

New brain imaging research at the University of North Carolina at Chapel Hill indicates that when people with autism look at a face, activity in the brain area that responds is similar to that of people without autism.

Gender affects the way a person's brain responds to humor

Need more evidence that men and women are different? Look no further than the Sunday funnies. According to a new Stanford University School of Medicine study, gender affects the way a person's brain responds to humor.

New device offers potential for accurate and reliable monitoring of brain oxygenation during cardiac surgeries

A new device that uses near-infrared light to non-invasively monitor the oxygenation of the brain during surgery appears to be a promising alternative to the more invasive techniques currently in use, according to a new study by Duke University Medical Center anesthesiologists.

Health benefits of different types of language use and writing contexts now explored

Researchers have known for some time that expressive writing can have a positive effect on the writer's health, such as illness recovery.

New insights into brain cell metabolism from PET and MRI scans

By discovering a crucial piece of submicroscopic information about how the brain converts fuel into energy for neurons, Cornell University biophysicists have gleaned new insights into brain cell metabolism that will allow neurologists to better interpret data from such diagnostic tests as positron emission tomography (PET) scans and a specialized magnetic resonance imaging (MRI) test.

Children who snore are far more likely to suffer hyperactivity disorders

Several years ago, University of Michigan researchers published some of the strongest evidence yet that children who snore when they sleep are far more likely to have attention and hyperactivity problems than their non-snoring peers.

Short-term use of CPAP therapy may protect against cardiovascular disease

A common sleep therapy used to treat patients with obstructive sleep apnea (OSA) may actually have a protective effect against death related to cardiovascular disease.

Scientists confirm rarefied air poses in-flight problem

More than half of all air passengers experience significant blood oxygen decreases at high altitudes, UK researchers report in the scientific journal Anaesthesia. We take a look at the findings and EU research in the aeronautics field.

Hospitalized babies with severe breathing problems may benefit from lying on their stomachs

Infants who are hospitalized with severe breathing problems may benefit from being placed on their stomachs rather than their backs, according to a new review of recent studies.

Images of brain activity may hold clues to the onset of schizophrenia

Images of brain activity may hold clues to the onset of schizophrenia in people at high risk for the disease, according to a study headed by psychiatry researchers at the University of North Carolina at Chapel Hill School of Medicine.

Mountaineering doctors hike medicine to new heights with Xtreme Everest

Doctors working at the edge of extreme are set to climb the world’s tallest mountain to look death in the face – and take its pulse. The medical research team will make the first ever measurements of blood oxygen in the ‘death zone’, at altitudes above 8,000 metres where the human body has struggled - and frequently failed - to survive.

New understanding of the causes for symptoms of sickle cell disease

A new understanding of the causes for symptoms of sickle cell disease, a condition affecting one in every 600 African-Americans, has resulted from a study by researchers at Duke University Medical Center and Howard Hughes Medical Institute (HHMI). Their findings may lead to a new, more direct method for treating the disease, they said.
