Using powerful new visualization technologies, researchers have captured the first 3-D images of the structure of a key muscle receptor, providing new insights on how muscles develop across the animal ...

Researchers at Imperial College London have discovered that specialist macrophages—a type of white blood cell—play a key role in the control of muscle contraction and locomotion. The discovery ...

Researchers engineered mice with a mutation (E3896A) in the RyR1 calcium-binding site, eliminating calcium-induced calcium release (CICR) without affecting depolarization-induced calcium release. The ...

Muscle contraction is the tightening, shortening, or lengthening of muscles when you do some activity. It can happen when you hold or pick up something, or when you stretch or exercise with weights.

The mechanism of skeletal muscle contraction is a process that relies on calcium signaling. However, the physiological role of calcium-induced calcium release (CICR) through the ryanodine receptor ...

Accomplishing perhaps a world first, researchers at Columbia University and the UChicago-affiliated Marine Biological Laboratory have mapped the full-body muscular activity of an animal while it was ...

Muscles play a part in every function of the body. The muscular system is made up of over 600 muscles. These include three muscle types: smooth, skeletal, and cardiac. Only skeletal muscles are ...

BOULDER, Colo.--(BUSINESS WIRE)--Edgewise Therapeutics, Inc., (Nasdaq: EWTX), a clinical-stage biopharmaceutical company focused on developing orally bioavailable, targeted, small molecule therapies ...

Though many people experience muscle twitching, it's often incorrectly identified as a muscle spasm. While both are involuntary contractions of a muscle, muscle spasms and muscle twitching aren't ...

If you've wondered how to swim, run or cycle for longer; perform more reps of an exercise in the gym; or just find everyday tasks like carrying shopping easier, you might consider working on your ...

Researchers at the Universities of Maynooth and Bonn discover a new connection in muscular dystrophy Duchenne muscular dystrophy (DMD) is the most common muscle disease in children and is passed on by ...

In a serendipitous discovery, UC San Diego researchers using cryo-EM technology captured the first visualizations of the 3-D structure of the muscle acetylcholine receptor in fetal and adult muscles.
