Researchers at the University of Maryland School of Medicine (UM SOM) have helped identify how a particular protein plays a central role in this astonishing consistency. This is the first time the mechanism has been described; the discovery could eventually help scientists treat heart problems that kill millions of people every year.
Tokyo, Dec 17, 2013 - (ACN Newswire) - Beginning with their discovery of spontaneous oscillatory contraction (SPOC) of muscle, Prof.
For the past 50 years, scientists and health professionals have operated with the knowledge that biceps are packed with long ropes of filaments. When the bicep is used to lift a heavy object or flex, these filaments were understood to shorten or contract the muscle and give it its power.
Muscle contraction and many other movement processes are controlled by the interplay between myosin and actin filaments.

Russians born during the Leningrad Siege in World War II, which was responsible for some of the greatest losses of civilian life in history, are giving scientists new strategies to identify people who experienced intrauterine growth restriction (IUGR) and starvation during childhood at greatest risk of developing long term heart complications.
Researchers at the University of Pennsylvania School of Medicine have discovered that a protein called leiomodin (Lmod) promotes the assembly of an important heart muscle protein called actin. Whatâ€™s more, Lmod directs the assembly of actin to form the pumping unit of the heart. The findings appear in this weekâ€™s issue of Science.
