The mechanism of skeletal muscle contraction is a process that relies on calcium signaling. However, the physiological role ...

The contraction of smooth muscle is an essential process underpinning diverse physiological functions ranging from gastrointestinal motility to vascular regulation. At its core, smooth muscle ...

Type IIb fast-twitch myofibers, known for their rapid contraction speed, are plentiful in small mammals but have largely ...

Researchers engineered mice with a mutation (E3896A) in the RyR1 calcium-binding site, eliminating calcium-induced calcium ...

A research team, led by an Indian-origin researcher, has provided new understanding of how heart muscle functions, by discovering the previously unknown role of two enzymes in heart Two hitherto ...

There are major shifts underway in understanding the physiological mechanisms that control muscle contraction, a field that has been the focus of intense research for centuries. A new article presents ...

Numerous motor and structural proteins compose a highly ordered structure known as the sarcomere, the basic unit of muscle contraction in heart and skeletal muscles. Sarcomeric myosin heavy chain ...

PHILADELPHIA -- The first view of the physical mechanism of how a blood clot contracts at the level of individual platelets is giving researchers from the Perelman School of Medicine at the University ...

Wenbo Chen and Misha Kudryashev from the Max Planck Institute of Biophysics and the Buchmann Institute for Molecular Life Sciences of the Goethe University Frankfurt, have succeeded in elucidating the ...

A new protein directs an existing heart muscle protein called actin to form a pumping unit in the heart, researchers at the University of Pennsylvania School of Medicine have reported. They discovered ...

The first view of the physical mechanism of how a blood clot contracts at the level of individual platelets is giving researchers a new look at a natural process that is part of blood clotting. The ...
