Power grid failure inside injured cardiac cells triggers post-heart attack arrhythmias

Heart attack survivors often experience dangerous heart rhythm disturbances during treatment designed to restore blood flow to the injured heart muscle, a common and confounding complication of an otherwise lifesaving intervention.

Study finds that skin exposure may trigger early peanut allergy in children

Many children may become allergic to peanuts before they first eat them, and skin exposure may be contribute to early sensitization, according to a study in mice led by Mount Sinai researchers and published today in the Journal of Clinical Investigation.

Conventional laparoscopy less complicated than robot-assisted surgery for benign gynecologic conditions

For benign gynecologic conditions, robot-assisted surgery involves more complications during surgery and may be significantly more expensive than conventional laparoscopic surgery, according to a study by researchers at Columbia University Medical Center.

Higher doses of neuroleptics needed for pregnant women with psychiatric conditions

The new generation of neuroleptics for psychiatric conditions has the advantage over older medications of fewer adverse side effects. An investigation into their effectiveness in pregnant women has now discovered that higher doses are needed during pregnancy to maintain the desired effect.

Researchers are developing compounds to combat causative agents of periodontitis

A total 12 million Germans suffer from periodontitis. If the inflammation remains untreated, this could lead to tooth loss. However, it is also suspected of triggering many other diseases, like cardiopulmonary diseases. Researchers are studying the interactions, and developing compounds to combat the causative agents.

Social status can impact health, happiness even among egalitarian forager-farmers

In western society, where keeping up with the Joneses — or, better yet, surpassing them — is expected and even encouraged, status matters. So important is it that for many people, physical and emotional wellbeing are directly connected to their place in the social hierarchy.

Stretch sensors respond weakly to muscle stretch caused by external forces

Stretch sensors in our muscles participate in reflexes that serve the subconscious control of posture and movement. According to a new study published in the Journal of Neuroscience, these sensors respond weakly to muscle stretch caused by one's voluntary action, and most strongly to stretch that is imposed by external forces. The ability to reflect causality in this manner can facilitate appropriate reflex control and accurate self-perception.

University of Luxembourg researchers identify potential new ways to test colorectal cancer

Researchers at the University of Luxembourg have identified potential new ways to test for the first signs of one of the most deadly types of cancer: colorectal cancer. They have found new "biomarkers": molecules whose increased presence or absence in tissue suggests the development of tumorous cells. These indicators could help detect colorectal cancer at an early stage, predict its severity or even offer new treatments.

Bedside ultrasound machine in pediatric ER is cost-effective, reduces length of stay in the ER

Using a portable or bedside ultrasound machine in the pediatric emergency room has been proven to lessen the length of stay in the ER and to provide images equal in accuracy to x-ray or CT scan without exposing children to potentially harmful radiation.

EPFL scientists discover two molecules that could overcome multidrug resistance in tuberculosis

Using a high-throughput screening assay, EPFL scientists have discovered two small molecules that could overcome the multidrug resistance of the bacterium that causes tuberculosis.

Women with healthy diet and lifestyle less likely to have stroke

Women with a healthy diet and lifestyle may be less likely to have a stroke by more than half, according to a study published in the October 8, 2014, online issue of Neurology, the medical journal of the American Academy of Neurology.

Specific perceptual learning deficit associated with Fragile X Syndrome

Researchers at Children's Hospital Los Angeles have described for the first time a specific perceptual learning deficit in mice with a mutation of the same gene as found in children with Fragile X Syndrome (FXS).

Bad sleep quality may trigger insomnia in older adults

Reports of insomnia are common among the elderly, but a new study finds that sleep problems may stem from the quality of rest and other health concerns more than the overall amount of sleep that patients get.

New model predicts replication rate in genome-wide studies based on SNP characteristics

To reduce false positives when identifying genetic variations associated with human disease through genome-wide association studies (GWAS), Dartmouth researchers have identified nine traits that are not dependent on P values to predict single nucleotide polymorphisms (SNP) reproducibility as reported in Human Genetics on October 2, 2014.
