The contractile ring [PDF]

open access: yesCurrent Biology, 2003
What is it? The contractile ring is a ring-shaped structure located just beneath the plasma membrane at the future division site in many, though not all, eukaryotic cell types. Composed of actin, myosin and many other proteins, it assembles in anaphase and contracts as cells divide. The contractile ring is responsible for cytokinesis in many eukaryotic

Contractility in an extensile system [PDF]

open access: yesSoft Matter, 2017
Essentially all biology is active and dynamic. Biological entities autonomously sense, com- pute, 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 ...

AI-Based Estimation of End-Systolic Elastance From Arm-Pressure and Systolic Time Intervals

open access: yesFrontiers in Artificial Intelligence, 2021
Left ventricular end-systolic elastance (Ees) is a major determinant of cardiac systolic function and ventricular-arterial interaction. Previous methods for the Ees estimation require the use of the echocardiographic ejection fraction (EF).

Contractility and Conformation [PDF]

open access: yesThe Journal of General Physiology, 1967
Contractility in fibers can arise from changes of macromolecular conformation caused by changes in some thermodynamic variable such as temperature, pH, or solvent composition. Illustrations are given of contractile processes in fibers and of changes in macromolecular conformation in dilute solution. These may involve order-disorder transitions, e.g. of

Long-Term Regulation of Excitation–Contraction Coupling and Oxidative Stress in Cardiac Myocytes by Pirfenidone

open access: yesFrontiers in Physiology, 2018
Pirfenidone (PFD) is used to treat human pulmonary fibrosis. Its administration to animals with distinct forms of cardiovascular disease results in striking improvement in cardiac performance.

Pathophysiological Mechanisms of Cardiac Dysfunction in Transgenic Mice with Viral Myocarditis

open access: yesCells, 2023
Viral myocarditis is pathologically associated with RNA viruses such as coxsackievirus B3 (CVB3), or more recently, with SARS-CoV-2, but despite intensive research, clinically proven treatment is limited.

Estimation of Left Ventricular End-Systolic Elastance From Brachial Pressure Waveform via Deep Learning

open access: yesFrontiers in Bioengineering and Biotechnology, 2021
Determination of left ventricular (LV) end-systolic elastance (Ees) is of utmost importance for assessing the cardiac systolic function and hemodynamical state in humans. Yet, the clinical use of Ees is not established due to the invasive nature and high

Force Measurements From Myofibril to Filament

open access: yesFrontiers in Physiology, 2022
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 whole animal to single molecules.

The contractile ring [PDF]

open access: yesCurrent Biology, 2011
What is the contractile ring? During cell division, the contractile ring generates the constricting force to separate one cell into two cells. Formed during cytokinesis, the last step of cell division, the contractile ring is composed of filamentous actin (F-actin) and the motor protein myosin-2, along with additional structural and regulatory proteins.
