Contractility in an extensile system

Contractility in an extensile system.

Essentially all biology is active and dynamic. Biological entities autonomously sense, compute, and respond using energy-coupled ratchets that can produce force and do work. The cytoskeleton, along with its associated proteins and motors, is a canonical example of biological active matter, which is responsible for cargo transport, cell motility, division, and morphology. Prior work on cytoskele...

Extensile actomyosin?

Living cells move thanks to assemblies of actin filaments and myosin motors that range from very organized striated muscle tissue to disordered intracellular bundles. The mechanisms powering these disordered structures are debated, and all models studied so far predict that they are contractile. We reexamine this prediction through a theoretical treatment of the interplay of three well-characte...

Extensile Exposure

IT is always stimulating, and sometimes very enlightening, to look at an old subject in a new way; and when a person has the gift of making others do so he is indeed a teacher. Professor Henry has this gift, to which is added a command over our language, and an evident love of it which almost defeats its own ends. There is a great temptation when reading this book to appreciate the English of e...

Supine Extensile Approach to the Anterolateral Humerus.

The radial nerve is at risk of injury during surgical approaches to the humeral shaft. Previous authors have described an anterolateral approach to the humerus limited by the radial nerve, requiring that distal dissection be carried anterior into a neurovascularly crowded interval. A novel extensile approach is described using a neuromuscular bridge to protect the radial nerve, thus enabling sa...
