Smk-1 is the first known gene that regulates longevity without disrupting life-sustaining function

Within a hormone-triggered cascade of molecular signals that plays a crucial for a wide range of physiological functions, researchers for the very first time have identified a protein that functions specifically to extend lifespan and youthfulness - without disrupting fertility

High levels of a salivary protein IL-1-beta associated with increased bone loss

Researchers at the University at Buffalo have identified two components of saliva that may serve as the basis for novel tests to determine the risk for future loss of the bone that holds teeth in place.

New approach to preventing recurrent febrile seizures in vulnerable children

It's one of those unavoidable facts of life - kids get sick and have fevers. Usually, those elevated internal temperatures cause only temporary discomfort, but in some small children they spark convulsions called "febrile seizures."

RvE1 protects from inflammation and bone loss in experimental periodontitis

Gum disease is initiated by bacteria populating dental plaque and may eventually result in tissue and tooth loss.

New AF267B drug reverses key cognitive deficits, pathology in Alzheimer's

A new drug that enhances the activity of a key brain cell receptor involved in Alzheimer's disease (AD) reverses learning and memory deficits in mice engineered to have pathological hallmarks of the disease.

Stroke researchers have traced the major cause of the death of brain cells

In the neurological train wreck that is stroke, researchers have traced the major cause of the death of brain cells due to artery blockage or bleeding in the brain.

Exposure to toxins from hazardous waste sites may be a significant risk factor for developing primary biliary cirrhosis

Published in the March 2006 issue of Hepatology, researchers found significant clusters of the disease near Superfund toxic waste sites (SFS) and that the majority of patients in New York City who need liver transplants because of PBC, reside near SFS.

Elderly people should not be afraid to exercise

Older people generally have to work harder than younger people to walk as fast or do other exercise, but some of the difference may be due to reduced exercise efficiency, which can be reversed with training.

Menthol discovery could point towards new pain therapies

This new understanding could lead to potential advances in pain therapy, the researchers said. Moreover, the scientists envision that their method may be potentially useful in studying the activation mechanism of other drugs and proteins.

Components found in red wine can help prevent periodontal diseases

Periodontitis is a progressive infectious disease affecting the gums and bone that surround and support teeth, often causing tooth movement and leading to permanent tooth loss.

Photodynamic therapy may be an effective treatment for infections of the oral cavity

Researchers found that the bacteria S. mutans, as well as fungal organisms of the genus Candida, cultured from HIV patients, were highly susceptible to killing with minimal doses of PDT, both in laboratory dishes and on biofilms grown on denture material.

A more accurate method for measuring blood levels of endothelial progenitor cells

A more accurate method for measuring blood levels of specialized cells that circulate in the bloodstream and repair damage to the arterial lining has been discovered by Duke University Medical Center cardiologists.

Sirolimus-releasing stents more effective than vascular brachytherapy for treating restenosis within a stent

David R. Holmes, Jr., M.D., of Mayo Clinic, Rochester, Minn., and colleagues with the SISR trial compared the use of vascular brachytherapy (VBT - intra-coronary radiation therapy) with implantation of the sirolimus-eluting stent for the treatment of restenosis occurring within a previously placed bare-metal stent

Using a growth factor to stimulate production of circulating endothelial progenitor cells improves cell production and mobility in arterial disease

Using a growth factor to stimulate production of circulating endothelial progenitor cells increases the numbers of these vascular regenerative cells, improves mobility, and potentially could improve blood vessel function in patients with peripheral arterial disease (PAD).

Hands-free impairs driving

Do you think using a hands-free device makes it okay to talk on a cell phone while driving? Despite the well-intended laws requiring the use of hands-free devices, a driver's performance is impaired when distracted by even the simplest tasks, whether or not both hands are on the steering wheel.
