United States has a major weight problem and it will get worse

A large, community-based study -- considered the first study to assess the long-term risk of developing overweight and obesity in adults -- found that over 30 years, nine out of 10 men and seven out of 10 women were overweight or became overweight. In addition, more than one in three were obese or became obese.

Use of the antibiotic amoxicillin during infancy appears to be linked to tooth enamel defects in permanent teeth

Dental fluorosis, a result of exposure to excessive fluoride during enamel formation, is one of the most common developmental enamel defects, according to background information in the article.

Bacteria of different species can talk to each other using a common language

The interspecies crosstalk and misdirection could have important consequences for human health, said Bonnie L. Bassler, an HHMI investigator at Princeton University whose study was published in the September 29, 2005, issue of Nature.

Mayo Clinic researchers find earliest sign of nerve change due to diabetes

Mayo Clinic researchers have found that subtle change in nerve conduction is the first reliable sign of nerve complications from diabetes and that this change can be measured long before other symptoms or signs of nerve damage develop.

First time a protein serving as a template for DNA synthesis seen

Since the discovery of the structure of DNA by James Watson and Francis Crick in 1953, the paradigm for DNA replication has stated that the DNA itself codes for the appropriate pairings for replication.

Discovery has implications for research on restoring mobility to people who have lost motor functions due to spinal cord injury

Yale School of Medicine researchers report in Science this week genetic evidence for the hypothesis that myelination, or formation of a protective sheath around a nerve fiber, consolidates neural circuitry by suppressing plasticity in the mature brain.

Discovery of mechanisms causing portal hypertension

A physician-scientist at UT Southwestern Medical Center and his research team have identified mechanisms causing a potentially deadly type of hypertension that results from liver damage – findings that could lead to its prevention.

Landmark study aims to find genetic link to Alzheimer's disease

More than 500 families affected by Alzheimer's Disease are participating in a landmark study led by Columbia University Medical Center to find a genetic link to the disease. That number will now double to 1,000 under a new $10 million five-year grant from National Institute on Aging.

Research on cartilage erosion and bone abnormalities

While characteristic of osteoarthritis (OA), a degenerative joint disease that affects some 20 million Americans, cartilage erosion and bone abnormalities are also associated with many rare hereditary conditions.

Behavior-based means of cutting the risks of tobacco

Three researchers who study behavior-based means of cutting the risks of tobacco use have made a case for counseling patients about the health risks of exposure to secondhand smoke when they're asked about direct tobacco use.

Brain mechanism may play a central role in regulating anxiety and alcohol-drinking

The finding, by researchers supported by the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health (NIH), could provide important clues about the neurobiology of alcohol-drinking behaviors in humans.

Body's own defenses may cause HIV-related dementia

Publishing in the Sept. 2005 issue of the Journal of Virology, the researchers show that HIV in the temporal lobe mutates at a rate 100 times faster than in other parts of the body, triggering white blood cells to continually swarm to attack the infection. The associated overcrowding and inflammation appear to cause the dementia.

Beta glucan may help treat skin disorders and remove fine lines and wrinkles

The fight against aging has received a scientific boost thanks to an innovative study done in part by a University of Alberta spin-off company--research that dispels a hard-held belief about the natural ingredient, beta glucan.

Potential biomarker that could be used to predict who might develop hepatic fibrosis

Two new studies on Hepatitis C (HCV) patients who underwent liver transplants examined a potential biomarker that could be used to predict who might develop hepatic fibrosis, a formation of scar-like tissue that can lead to cirrhosis.

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.
