What every ICU clinician needs to know about the cardiovascular effects caused by abdominal hypertension [PDF]
, 2015 The effects of increased intra-abdominal pressure (IAP) on cardiovascular function are well recognized and include a combined negative effect on preload, afterload and contractility.

Improved ventricular function during inhalation of PGI(2) aerosol partly relies on enhanced myocardial contractility [PDF]
, 2005 Inhaled prostacyclin (PGI(2)) aerosol induces selective pulmonary vasodilation. Further, it improves right ventricular ( RV) function, which may largely rely on pulmonary vasodilation, but also on enhanced myocardial contractility.

A novel method to extend viability and functionality of living heart slices
Frontiers in Cardiovascular Medicine, 2023 Living heart slices have recently emerged as a powerful experimental model for fundamental cardiac research. By retaining the structure and function of the native myocardium while maintaining the simplicity of cell culture models, heart slices can be ...

Long Prehensile Protrusions Can Facilitate Cancer Cell Invasion through the Basement Membrane
Cells, 2023 A basic process in cancer is the breaching of basement-membrane barriers to permit tissue invasion. Cancer cells can use proteases and physical mechanisms to produce initial holes in basement membranes, but how cells squeeze through this barrier into ...

Child’s heart development and contractility from prenatal to postnatal period
Российский кардиологический журнал, 2022 This literature review analyzes current data on the main stages of child’s heart contractility development from prenatal to postnatal period. The presented information will expand the conventional ideas on the age-related cardiovascular physiology in ...

Contractility and Conformation [PDF]
The 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

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016 BackgroundPigment epithelium‐derived factor (PEDF), which belongs to the noninhibitory serpin family, has shown the ability to stimulate several physiological processes, such as antiangiogenesis, anti‐inflammation, and antioxidation. In the present study,
