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 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 ...
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 ...
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 ...
Type 2 diabetes doesn’t just raise the risk of heart disease—it physically reshapes the heart itself. Researchers studying ...
Type 2 diabetes physically alters heart muscle, energy use and structure, a human heart study finds, explaining why people ...
A mouse study of heart failure with preserved ejection fraction (HFpEF) found male-female differences at the cellular level. The findings could have implications for how HFpEF is treated in women ...
