A new study from American Cancer Society researchers finds it's not just how much physical activity you get, but how much time you spend sitting that can affect your risk of death.

In a joint study, scientists from The Scripps Research Institute and the Dana-Farber Cancer Institute at Harvard University have uncovered a novel mechanism that dramatically increases insulin sensitivity and reduces the risk of developing type 2 diabetes and cardiovascular disease.

Patients who had experienced a heart attack and lowered their blood homocysteine levels with folic acid and vitamin B12 supplementation did not have an associated lower risk of heart attack, coronary death or stroke, according to a study in the June 23/30 issue of JAMA. However, the researchers did find that folic acid supplementation did not increase the risk of cancer, which has been speculated.

A diet rich in natural antioxidants improves insulin sensitivity in insulin-resistant obese adults and enhances the effect of the insulin-sensitizing drug metformin, a preliminary study from Italy finds.

Doctors have long known that snoring is hazardous to health for a number of reasons. In addition to restless nights and increased daytime sleepiness, sleep-disordered breathing (SDB) has a series of associated health problems, including increased risk of cardiovascular disease (CVD).

People with larger stomachs in their 40s are more likely to have dementia when they reach their 70s, according to a new study. The study involved 6,583 people age 40 to 45 in northern California who had their abdominal fat measured. An average of 36 years later, 16 percent of the participants had been diagnosed with dementia.

A protein called fibrinogen that is known to help form blood clots also triggers scar formation in the brain and spinal cord, according to new research in the April 28 issue of the Journal of Neuroscience. Researchers found that fibrinogen carries a dormant factor that activates when it enters the brain after...

Fibrinogen, a blood-clotting protein found in circulating blood, has been found to inhibit the growth of central nervous system neuronal cells, a process that is necessary for the regeneration of the spinal cord after traumatic injury.

Excessive sleepiness is more common in the U.S. than in Europe, which raises concerns for public health and safety, according to a research abstract presented June 8, 2010, in San Antonio, Texas, at SLEEP 2010, the 24th annual meeting of the Associated Professional Sleep Societies LLC.

Individuals with chronic insomnia have an elevated risk of death, according to a research abstract presented June 7, 2010, in San Antonio, Texas, at SLEEP 2010, the 24th annual meeting of the Associated Professional Sleep Societies LLC.

People who take aspirin regularly for a year or more may be at an increased risk of developing Crohn's disease, according to a new study by the University of East Anglia (UEA).

In addition to crystallized cholesterol, atherosclerotic plaques always contain large quantities of immune cells but, surprisingly, no bacteria or viruses. It was previously unclear just how the body's own defence forces are called into action. Even animals that are kept in an absolutely sterile environment can suffer from "clogging" or "furring" of the arteries when their food contains high levels of cholesterol. The same relationship is found in humans.
