Myocardial contractile reserve and indices of contractility
Cardiovascular Research, 1976A close examiniation of several indices of contractility derived from the ventricular pressure was made using an isolated canine heart preparation. The repsonses to single intracoronary injections of calcium chloride as well as to increasing doses of this agent were tested.

Contractile ring composition dictates kinetics of in silico contractility
Biophysical Journal, 2023Constriction kinetics of the cytokinetic ring are expected to depend on dynamic adjustment of contractile ring composition, but the impact of ring component abundance dynamics on ring constriction is understudied. Computational models generally assume that contractile networks maintain constant total amounts of components, which is not always true.

This chapter summarizes the structure, function, and dysfunction of various contractile systems, including muscle (skeletal, cardiac, smooth) and nonmuscle entities (actin, cilia). Motility requires a specific arrangement of proteins, along with proper chemomechanical transduction. Muscle innervation varies according to muscle type.

Regulation of Myocardial Contractility
Journal of Cardiovascular Pharmacology, 1995The definition of myocardial contractility remains complex and its exact measurement remains difficult, especially in the intact heart. Measurement of load-independent effects requires sophisticated equipment and preparations that are not applicable to clinical practice.

A perspective on myocardial contractility
Technology and Health Care, 1997Myocardial contractile properties form the cornerstone of the heart's ability to pump blood. Efforts have been made to characterize these properties via classic elasticity theory concepts, which can lead to spurious results, as demonstrated by experiments measuring intramyocardial pressure. Two ways out of these difficulties are identified.

Polymorphism of contractile proteins
Biopolymers, 1987Contractile proteins are present as multiple isoforms encoded by multigene families. The numbers of known isoforms of the myosins, actins, tropomyosins, and troponins are summarized, and the mechanisms by which this diversity has been generated are discussed. Two major strategies can be distinguished, one that depends on gene duplication events leading

Abstract 1.1. A contractile protein from term placentas has been isolated and characterized. 2.2. This contractile protein is closely related, if not identical, to actomyosin. 3.3. The role of this contractile protein in maintenance of placental circulation is discussed.
