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.

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...

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.

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).

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.

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.

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.

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.

Melinda Sothern, PhD, CEP, Professor of Public Health and Director of Health Promotion at LSU Health Sciences Center New Orleans, will present evidence that supports relationships seen in adolescents between insulin sensitivity and fatty liver, belly fat, and total body fat and identifies additional potential early markers of insulin resistance and metabolic syndrome in healthy 7-9 year-old children, including fat in muscle cells, blood pressure, physical activity, and birth weight.

Calcium supplements, commonly taken by older people for osteoporosis, are associated with an increased risk of a heart attack, finds a study published online in the British Medical Journal. The results suggest that a reassessment of the role of calcium supplements in osteoporosis management is needed.

People whose blood shows signs of inflammation are more likely to later develop Alzheimer's disease than people with no signs of inflammation, according to a study published in the May 29, 2007, issue of Neurology®, the scientific journal of the American Academy of Neurology.

Harvard University researchers have uncovered a mechanism through which caloric restriction and exercise delay some of the debilitating effects of aging by rejuvenating connections between nerves and the muscles that they control.
