Osaka, Japan - Researchers at Osaka University used electron cryomicroscopy (CryoEM) to image essential cardiac muscle components, known as thin filaments, with unprecedented resolution. They also ...

Each cardiac muscle cell can have over 5,000 sarcomeres, which compounds both the shortening and relaxation events. "This process appears to be regulated by myosin-binding protein-C (cMyBP-C), which ...

Since early in the pandemic, COVID-19 has been associated with heart problems, including reduced ability to pump blood and abnormal heart rhythms. But it's been an open question whether these problems ...

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 from the Heart Center of the University Medical Center Göttingen (UMG) led by Priv.-Doz. Dr. Sören Brandenburg have identified a protein that plays a central role in the heart's adaptation ...

Mammalian hearts have almost no ability to grow new heart muscle cells, called cardiomyocytes, after birth. Thus, dead tissue after an adult heart attack is not repaired with new cardiomyocytes. It is ...
