Heart-protective protein finally found

It is a cellular component so scarce, some scientists even doubted its existence, and many others gave up searching for its molecular structure. Now a team led by researchers at Johns Hopkins has defined the protein structural composition of mitoKATP, a potassium channel in the mitochondria of the heart and other organs that is known to protect against tissue damage due to a heart attack or stroke.

Study investigates how glucose metabolism affects biochemical signals in cancer cells

Compared to normal cells, cancer cells have a prodigious appetite for glucose, the result of a shift in cell metabolism known as aerobic glycolysis or the "Warburg effect." Researchers focusing on this effect as a possible target for cancer therapies have examined how biochemical signals present in cancer cells regulate the altered metabolic state.

The stakes of the decision

A new Reuters/Ipsos poll shows that though most Americans continue to oppose the health law, they support many of its provisions. Meanwhile, news outlets continue to report on what the impact would be -- both in terms of people and the markets -- if the law is overturned and these provisions are rolled back.

Scientists recommend new type of therapeutic approach to dementia

Scientists at Charité - Universitätsmedizin Berlin have succeeded in recommending a new type of therapeutic approach to dementia. The study published in the journal Neurology shows that immune reactions against the body's own nerve cells can be the cause of advanced dementia and an appropriate immune suppressive therapy can develop with significant effectiveness.
