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.

Can weight loss reverse heart failure? A new study shows that heart muscle cells regain strength and muscle contractions ...

A new study suggests severe obesity may weaken heart muscle cells in people with heart failure with preserved ejection ...

From the microscopic dance of actin and myosin to the full-body power you feel in a workout, muscle contraction is a precise, coordinated process. It starts with a nerve signal, triggers calcium ...

The study, published in Developmental Cell, further shows that the resting tension in the heart cells is increased after a heart attack and other heart diseases. This changes the way that heart cells ...

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 ...

Diseased hearts may be thrown out of rhythm by structural differences -- now visible for the first time -- in protein groups that connect heart muscle cells, according to the authors of a study to be ...

A Johns Hopkins-led study reports that severe obesity in people with heart failure with preserved ejection fraction (HFpEF) is linked to weakened contraction of heart muscle cells, but this defect may ...
