A novel study that attempts to paint the most accurate and detailed description yet of how Americans experience pain has found that a significant portion of the population -- 28 percent -- are in pain at any given moment and those with less education and lower income spend more of their time in pain. Those in pain are less likely to work or socialize with others and are more inclined to watch television than the pain-free.

Based on research using a new mouse model of gastritis and stomach cancer, researchers say that prompt treatment of Helicobacter pylori infections reverses damage to the lining of the stomach that can lead to cancer.

Ever since Ernest Moore's ears began ringing with tinnitus, he has been researching a cure. There's a lot riding on his work. Tinnitus is the top disability of soldiers returning from Iraq and Afghanistan, caused by the noise of explosive devices. Moore, a former soldier and an audiologist, is doing cutting edge research with zebrafish that may offer a solution as new funding from the Department of Defense opens up.

Researchers have discovered how some bacteria can survive antibiotic treatment by turning on resistance mechanisms when exposed to the drugs. The findings could lead to more effective antibiotics to treat a variety of infections.

A technique called microscopic X-ray computed tomography (microCT) is affording scientists the ability to visualize even the subtlest birth defects in prenatal and postnatal bats, mice, opossums and primates, which one day may lead to new understandings about human birth defects.

A common component of the contraceptive pill could improve the neurologic outcome for patients with severe head injuries, according to a new study. Traumatic brain injury (TBI), such as that caused by traffic accidents, falls and sporting injuries, is a major cause of death and disability. A number of 'neuroprotective' drugs have been shown to prevent nerve-cell death in animal models of traumatic brain injury, but these findings have not been translated into trials involving people with head injuries.

Low-dose antidepressant therapy can significantly improve the overall quality of life for adolescents suffering from irritable bowel syndrome, or IBS. The study is the first of its kind to look at the effects of amitriptyline, a tricyclic antidepressant, in the pediatric IBS population.

Cross-sectional studies from around the world show a consistent increased risk of obesity among short sleepers in children and adults. This study showed a consistent pattern of increased odds of being a short sleeper if you are obese, both in childhood and adulthood.

Older nursing home residents who took medications for dementia and incontinence at the same time had a 50 percent faster decline in function than those who were being treated only for dementia, according to a study from researchers at Wake Forest University School of Medicine and colleagues.

Diabetic individuals have a significantly higher risk of developing Alzheimer's disease but the molecular connection between the two remains unexplained. Now, researchers have identified the probable molecular basis for the diabetes -- Alzheimer's interaction.
