The fluid and the cells inside lymphatic vessels are collectively known as lymph, and although the lymphatic system extends to every part of the body, there is no central pump like the heart to keep ...

Studying why heart cells are less likely to become cancerous can provide clues to improving heart regeneration and treatments for heart disease.

Because of the observed increase in myostatin after cardiac stress, and its known functions regulating muscle growth and differentiation, one hypothesis is that heart failure increases ...

Many cancer survivors struggle with muscle weakness, which can be so profound that they may have difficulties walking up a ...

Bioluminescent imaging is helping researchers better understand the effectiveness of tissue regeneration enhancers delivered to injured heart tissue by different adeno-associated virus vectors.

Zebrafish have the rare ability to regenerate their heart muscle after major damage, unlike humans. Researchers have now ...

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 ...

Why It Matters Myocarditis, when the heart muscle gets inflamed, can make it harder for the heart to pump blood possibly causing chest pain, shortness of breath and irregular heartbeats.

After only two weeks in space, muscle strength trended to decline in the young tissues and was now more comparable to the strength of old tissues.

The series elasticity (SE) of cat papillary muscle was measured in 6 muscles by the isotonic quick-release method, with careful correction for the compliance of the equipment. The resultant SE curve ...

Scientists have found a novel way that includes a new lab-grown material that could help slow and even reverse some of the effects of aging in the heart.
