Tokyo, Dec 17, 2013 - (ACN Newswire) - Beginning with their discovery of spontaneous oscillatory contraction (SPOC) of muscle, Prof. Shin'ichi Ishiwata and his team at Waseda University's Faculty of Science and Engineering have been experimentally characterizing this phenomenon over the last 25 years. Recently, the team, in collaboration with Dr. Katsuhiko Sato of the RIKEN Center for Developmental Biology (Kobe) and Vice Director Yoshiki Kuramoto of the International Institute for Advanced...

New Research Challenges 50 Years Of Muscle Knowledge

Michael Harper for redOrbit.com - Your Universe Online 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. A new study from the University of Washington (UW) challenges this notion, saying that while the general idea of filaments contracting is the same,...

Max Planck scientists bring the basis of muscle movement into sharper focus Muscle contraction and many other movement processes are controlled by the interplay between myosin and actin filaments. Two further proteins, tropomyosin and troponin, regulate how myosin binds to actin. While theoretical models have in fact described exactly how these muscle proteins interact, this interaction has never previously been observed in detail. Stefan Raunser and Elmar Behrmann from the Max Planck...

Cardiomyopathy comprises a deterioration of the heart muscle that affects the organ's ability to efficiently pump blood through the body. Previously researchers have tied forms of the disease to the alternative splicing of titin, a giant protein that determines the structure and biomechanical properties of the heart, but the molecular mechanism remained unknown. Professor Michael Gotthardt and Professor Norbert Hübner of the Max Delbrück Center for Molecular...

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.vThe abstract study´, presented at the Frontiers in CardioVascular Biology (FCVB) meeting, in London, UK, 30 March to 1 April 2012, makes use of a...

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. What's more, Lmod directs the assembly of actin to form the pumping unit of the heart. The findings appear in this week's issue of Science."Very little was known about Lmod when we began this study," says lead author Roberto Dominguez, PhD, Associate Professor of Physiology. "It appeared that this...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
