Protein found in the brain is genetically linked to alcoholism and anxiety

The researchers studied rats selectively bred for high alcohol preference (P rats), which were found to have high anxiety levels and consume greater amounts of alcohol than alcohol non-preferring (NP) rats.

Chemical in cocoa beans can limit the development of fluids that cause diarrhea

A new study conducted by researchers at Children's Hospital & Research Center Oakland is the first to discover that a chemical in cocoa beans can limit the development of fluids that cause diarrhea. Cocoa beans contain a large amount of chemicals called flavonoids.

Researchers set out to determine the effectiveness of endomorphin 1, with a painkilling capacity equal to or greater than morphine

Nearly one third of the world's adult population suffers with the pain of arthritis. While NSAIDs and COX-2 inhibitors offer the promise of relief, these drugs also bring the risk of adverse effects, from stomach ulcers to heart attack.

Important developmental link between the cerebrum and the cerebellum

Higher cognitive functions, like language and visual processing, have long been thought to reside primarily in the brain's cerebrum. But a body of research in premature infants at Children's Hospital Boston is documenting an important role for the cerebellum

Lack of oxygen in body tissues creates a defect of red blood cells that further exacerbates the condition by constricting blood vessels in the lung

What's more, the team demonstrated through studies in people and animals that inhalation of a 'souped up' form of nitric oxide, which targets red blood cells, reverses the blood abnormality to restore normal lung pressure.

Australia's leading medical research institutes recognise that the Australian Synchrotron

The President of the Australian Association of Medical Research Institutes (AAMRI), Professor Suzanne Cory, has announced that AAMRI would become a partner in the Australian Synchrotron.

Cost-effective technique for reducing mercury emissions from coal-fired power plants

Researchers at Lehigh University's Energy Research Center (ERC) have developed and successfully tested a cost-effective technique for reducing mercury emissions from coal-fired power plants.

The biomedical and sociological effects of sleep restriction

In spring 2005 a large European research and training network was established to investigate the causes and implications of poor sleep from the medical as well as from the social point of view.

Brain abnormalities in people who habitually lie

While previous research has shown that there is heightened activity in the prefrontal cortex - the area of the brain that enables most people to feel remorse or learn moral behavior - when normal people lie, this is the first study to provide evidence of structural differences in that area among pathological liars.

Compounds secreted by frog skin are potent blockers of HIV infection

The findings could lead to topical treatments for preventing HIV transmission, and they reinforce the value of preserving the Earth's biodiversity.

Doctors should encourage teens to limit their intake of food prepared away from home and to eat family dinners together

New research shows that adolescents who eat large amounts of fried food away from home are heavier and more likely to have a poor-quality diet.

Researchers have successfully combined computer modeling and experimental results in folding studies for small proteins

In unprecedented new research, scientists at Rice University have combined theory and experiment for the first time to both predict theoretically and verify experimentally the protein-folding dynamics of a large, complex protein.

New insights that advance the current model of protein motility and muscle contraction

Scientists from the Burnham Institute for Medical Research and the University of Vermont have captured the first 3-dimensional (3D) atomic-resolution images of the motor protein myosin V as it "walks" along other proteins, revealing new structural insights that advance the current model of protein motility and muscle contraction.

Sharper picture than previously available of major depressive disorder

Findings from the largest survey ever mounted on the co-occurrence of psychiatric disorders among U.S. adults afford a sharper picture than previously available of major depressive disorder (MDD) in specific population subgroups and of MDD's relationship to alcohol use disorders (AUDs) and other mental health conditions.

Scientists measure with unprecedented accuracy the strengths of hydrogen bonds in a protein

The scientists were then able to predict the function of different versions of the protein based on structural information, a novel outcome that was published recently in the Proceedings of the National Academy of Sciences.

First direct clues about how the brain alters the state of consciousness during sleep

In the human brain, cells talk to one another through the routine exchange of electrical signals. But when people fall into a deep sleep, the higher regions of the brain - regions that during waking hours are a bustling grid of neural dialogue - apparently lose their ability to communicate effectively, causing consciousness to fade.

Discovery of mechanism in the body that could lead to autoimmune diseases

Researchers at National Jewish Medical and Research Center have discovered a mechanism in the body that could lead to autoimmune diseases, such as lupus, rheumatoid arthritis, or diabetes.

Lab-made version of a human protein opens a new research avenue to better understand rheumatoid arthritis

A lab-made version of a human protein alleviates symptoms of both acute and chronic arthritis in mice and could be the basis for a new arthritis drug for people, report scientists from the National Institute of Allergy and Infectious Disease (NIAID), part of the National Institutes of Health (NIH).

Steroids significantly reduce heart damage in children with Kawasaki's disease

When added to standard treatment, steroids significantly reduce the odds of developing heart damage in children with Kawasaki's disease, according to a study in the October issue of Pediatrics. These findings address a gap in knowledge.

Plant-derived compounds appear to block the activity of an enzyme that triggers inflammation in joints

The findings came to light while the researchers were studying the wildly different ways in which cells in human blood vessels and joints respond to pressure gradients generated from liquid moving along their surface, a force called shear stress.
