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 ...

The human heart, often described as the body's engine, is a remarkable organ that tirelessly beats to keep us alive. At the core of this vital organ, intricate processes occur when it contracts, where ...

A team of researchers have discovered that a mutation in a ribosomal protein found specifically in heart and skeletal muscle leads to impaired cardiac contractility in mice. The mutation was found to ...

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 ...

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 ...

Researchers find that deficiency in RPL3L, a ribosome expressed in heart and skeletal muscle, impairs cardiac contractility due to delayed mRNA translation Fukuoka, Japan—A team of researchers have ...

The heart is the body's hardest-working muscle. Whether you're awake or asleep, or exercising or resting, your heart is always at work. It pumps blood through arteries to deliver oxygen to organs and ...

Cancer patients often lose excessive amounts of weight. This affects up to 80% of patients and is mainly due to a decrease in ...
