The studies, which would not have been possible a year or two ago, are the first real delivery of the promised transformation of medical science from the Human Genome Project’s mapping of the human genetic code. One was also made possible by some of the $5 billion that U.S. President Barack Obama directed to the National Institutes of Health in September from the $787 billion economic ...

It is not yet clear what the finding may mean for humans because the disease was found in mice, the study authors noted in the report published online March 5 in PLoS Pathogens. However, the disease does seem to be similar to two newly reported cases of the prion disease known as Gerstmann-Straussler-Scheinker syndrome, according to the researchers from the U.S. National Institute of A...

Researchers from the University of Pennsylvania in Philadelphia and Washington University in St. Louis studied 872 women with and without gum disease who were pregnant for between six and 20 weeks. Of that group, 160 with gum disease were treated and later evaluated to see whether the treatment had been successful. About 7 percent of the women without gum disease gave birth before 35 w...

After adjusting for common cardiovascular disease risk factors, the study found that while A1C levels high enough to diagnose diabetes were associated with nearly twice the risk of coronary heart disease, no such association was found with fasting glucose readings high enough to trigger a diabetes diagnosis. The A1C test is also known as a glycated hemoglobin test, and using a small bl...

Researchers, led by Chinese scientist Wang Jun, said in the latest issue of Nature they found more than 1,000 different species of bacteria in the human gut. They said they had sequenced, or analyzed, the genes of each bacteria, creating the first genetic catalog of the organisms found in the human digestive system. Their research was based on analysis of stool samples from 124 people from D...

British researchers scanned the genetic maps of more than 9,400 celiac patients and found areas of immune system disturbance which lead to the development of the auto-immune disease, which affects around one percent of people. The researchers also found "substantial evidence" that genes associated with celiac disease may also be linked to many other common chronic immune diseases, such as ty...

Lupus is an autoimmune illess in which the immune system creates antibodies that attack the body’s own cells, causing widespread inflammation that results in damage to tissue and organs, including the heart, kidneys, brain, blood, skin and joints. In this study, Australian and British researchers found that patients with active lupus had significantly increased levels of autoantibodies...

The concern, say researchers, is that patients and doctors may interpret any resulting activity limitations as a sign that the lung disease is worsening, when it could instead be a shortcoming of the oxygen device. The devices in question, known as oxygen conservers, are used mainly by people with chronic obstructive pulmonary disease (COPD), a group of lung diseases that includes emphysema ...

Research has shown that saturated fat can raise blood levels of "bad" LDL cholesterol, and elevated LDL is a risk factor for heart disease and stroke. Because of this, experts generally advise people to limit their intake of fatty meat, butter and full-fat dairy. The American Heart Association (AHA) suggests that adults get no more than 7 percent of their daily calories from the fat; for som...

The study, published in the British Medical Journal, involved 86,611 survivors from the bombings of Hiroshima and Nagasaki in 1945, which forced Japan into surrendering to the Allied Powers and officially ending World War Two. Each person was exposed to an absorbed radiation dose of between 0 and 4 Gy (Gray) at the time of the bombings. Gray is the unit measuring absorbed radiation ...
