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 ...

THE function of the heart is to propel unoxygenated blood to the lungs and to deliver oxygenated blood to the peripheral tissues in accordance with their metabolic requirements. Since William Harvey's ...

Research led by Muhammad Riaz, Ph.D., Jinkyu Park, Ph.D., and Lorenzo Sewanan, MD, Ph.D., from the Qyang and Campbell laboratories at Yale, provides a mechanism to identify abnormalities linked with a ...

Numerous motor and structural proteins compose a highly ordered structure known as the sarcomere, the basic unit of muscle contraction in heart and skeletal muscles. Sarcomeric myosin heavy chain ...

The Moore lab investigates how proteins build contractile systems that power cells and whole organisms. Collaboratively, we connect molecular mechanisms to tissue-level performance using ...

Research has uncovered how motor protein myosin, which is responsible for contraction of skeletal muscles, functions also in non-muscle cells to build contractile structures at the inner face of the ...

The paper by Parmley et al. in this issue calls attention to the possible therapeutic use of glucagon in view of its possible inotropic and chronotropic effects in man. Such effects have previously ...

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 ...

Segments of the obliquely striated body muscle of Ascaris were fixed at minimum body length after treatment with acetylcholine and at maximum body length after treatment with piperazine citrate and ...
