Study calls heart imaging into question for mild chest pain

March 14, 2015 2:05 pm | by Marilynn Marchione, AP Chief Medical Writer, Associated Press | News | Comments

A big federal study finds that people who see a doctor for chest pain have no less risk of suffering a heart attack, dying or being hospitalized later if they are checked with a fancy newer type of CT scan rather than a simple treadmill test or other older exam. CT scans, a type of x-ray that gives a very detailed look at heart arteries, have been used for about a decade without evidence they are better or worse than older tests.

Voltage tester for beating cardiac cells

February 18, 2015 9:36 am | by ETH Zurich | News | Comments

Electrical impulses play an important role in cells of the human body. For example, neurons use these impulses to transmit information along their branches and the body also uses them to control the contraction of muscles. The impulses are generated when special channel proteins open in the outer envelope of the cells, allowing charged molecules (ions) to enter or exit the cell. These proteins are referred to as ion channels.
