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

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.

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 ...

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 ...

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 ...

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 ...

Engineers interested in creating artificial cells to deliver drugs to unhealthy parts of the body face a key challenge: for a ...
