Myofibrils are cylindrical organelles found within muscle cells (also known as muscle fibers). These highly organized structures are composed of repeating units called sarcomeres, which are the basic ...

Abstract: A high performance device for measuring force and length change during myofibril contraction is fabricated. The principle of a device depends on the law of electromagnetic induction.

Hypothesis: Myofibril mechanics and transcriptomic studies will better discriminate TNNI3 A158V mice from WT than previous phenotyping studies. Methods: Heart tissue was obtained from wild-type (WT) ...

Researchers have just made the unexpected discovery of a novel organization of muscle fibers in Parophidion vassali, a fish that lives in the Mediterranean Sea and, like many fish, uses specialized ...

Costameres, as striated muscle-specific cell adhesions, anchor both M-lines and Z-lines of the sarcomeres to the extracellular matrix. Previous studies have demonstrated that costameres intimately ...

Contractility, the generation of force and movement by molecular motors, is the hallmark of all muscles, including striated muscle. Contractility can be studied at every level of organization from a ...

Skeletal muscles are composed of gigantic cells called muscle fibers, packed with force-producing myofibrils. During development, the size of individual muscle fibers must dramatically enlarge to ...

Stephen Greenspan and Laura Zah were devastated when they learned their son Alexander had a rare genetic mutation, which causes a deadly neuromuscular disease with no known treatment or cure. But the ...

WASHINGTON, May 19, 2020 -- Heart disease is the leading cause of death in the United States and other industrialized nations, and many patients face limited treatment options. Fortunately, stem cell ...
