Developmental Changes in the Excitation–Contraction Mechanisms of the Ventricular Myocardium and Their Sympathetic Regulation in Small Experimental Animals

Journal of Cardiovascular Development and Disease
The developmental changes in the excitation–contraction mechanisms of the ventricular myocardium of small animals (guinea pig, rat, mouse) and their sympathetic regulation will be summarized.

The Ultrastructure of Developing Sarcoplasmic Reticulum

Journal of Biological Chemistry, 1974
Developmental changes in the sarcoplasmic reticulum and surface membranes of chicken skeletal muscles were investigated by electron microscopy. A dominant feature of freeze-etched sarcoplasmic reticulum membranes isolated from adult animals is the presence of spherical intramembranous particles of 75 A apparent diameter which are more numerous on the ...

An investigation of NAADP-dependent Ca²⁺ signalling mechanisms in arterial smooth muscle [PDF]

, 2007
Previous investigations on pulmonary artery smooth muscle cells have shown that nicotinic acid adenine dinucleotide diphosphate (NAADP) evokes highly localised intracellular Ca²⁺ bursts by mobilising thapsigargin-insensitive Ca²⁺ stores.

Organelle Optogenetics: Direct Manipulation of Intracellular Ca2+ Dynamics by Light

Frontiers in Neuroscience, 2018
As one of the ubiquitous second messengers, the intracellular Ca2+, has been revealed to be a pivotal regulator of various cellular functions. Two major sources are involved in the initiation of Ca2+-dependent signals: influx from the extracellular space

Penile intracavernosal injection of succinylcholine for laryngospasm management during hypospadias repair

UroPrecision, EarlyView.
Abstract Background Laryngospasm is a serious anesthetic complication that can lead to acute airway obstruction and hypoxemia. Standard management involves deepening anesthesia and administering succinylcholine intravenously (IV) or intramuscularly (IM). However, if IV access is lost or IM drug delivery is too slow, alternative routes are required.

Impaired Sarcoplasmic Reticulum Calcium Uptake and Release Promote Electromechanically and Spatially Discordant Alternans: A Computational Study

, 2016
Cardiac electrical dynamics are governed by cellular-level properties, such as action potential duration (APD) restitution and intracellular calcium (Ca) handling, and tissue-level properties, including conduction velocity restitution and cell–cell ...

Increased energetic cost of movement reduces reproductive output in zebrafish at different temperatures and water flow rates

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Locomotion consumes a large proportion of individual energy budgets and may impose energetic constraints on other fitness‐related traits particularly under variable environmental conditions.

Calcium sparks in arterial smooth muscle cells regulate vascular tone

Journal of Biological Research, 2002
It is named Ca2+ sparks a local, rapid and transient Ca2+ release from sarcoplasmic reticulum (SR) by the opening of ryanodine-sensitive (RyR) channels. RyR channels localized in SR are found in all muscle cell types (cardiac, skeletal, smooth) and many
