Researchers at UT Southwestern Medical Center have identified a previously unrecognized small protein in cells of the human heart that plays a key role in heart muscle contraction. The protein is made ...

Researchers at the University of California, Irvine, have developed a polymeric biohybrid cardiac device that harnesses the ...

Researchers have investigated the effect of increased cell temperature on the contractility of skeletal muscle and cardiac muscle by heating the muscle proteins using advanced microscopical techniques ...

No one can live without a heart pumping blood to the rest of the body. New research from the University of Missouri School of Medicine reveals more information about this vital function and how it’s ...

When a muscle contracts, the parts of a sarcomere "shorten" and come closer together. Each cardiac muscle cell can have over 5,000 sarcomeres, which compounds both the shortening and relaxation events ...

What makes a body’s organs into what they are is more than just a grouping of specialized cells. They also need to be oriented and attached to each other and scaffolding in order to create structures ...

3D heart on a chip technology: A tiny, lab-grown piece of beating heart tissue may soon help scientists answer a question that has long been difficult: how will a real human heart respond to a drug or ...

Most people view their calf muscles solely through the lens of aesthetics or athletic power, but they are actually critical components of your circulatory system. Often referred to by medical ...
