Mapping the spatiotemporal dynamics of calcium signaling in cellular neural networks using optical flow [PDF]
, 2010 An optical flow gradient algorithm was applied to spontaneously forming net- works of neurons and glia in culture imaged by fluorescence optical microscopy in order to map functional calcium signaling with single pixel resolution.

Calcium Signaling in ß-cell Physiology and Pathology: A Revisit
International Journal of Molecular Sciences, 2019 Pancreatic beta (β) cell dysfunction results in compromised insulin release and, thus, failed regulation of blood glucose levels. This forms the backbone of the development of diabetes mellitus (DM), a disease that affects a significant portion of the ...

Calcium at the Crossroads of Signaling [PDF]
The Plant Cell, 2002 ### Calcium Signals: A Central Paradigm in Stimulus–Response Coupling Cells must respond to an array of environmental and developmental cues. The signaling networks that have evolved to generate appropriate cellular responses are varied and are normally composed of elements that include ...

Examining the Effect of Introducing a Link from Electrical Excitation to Calcium Dynamics in a Cardiomyocyte [PDF]
, 2016 Calcium dysregulation is a significant cause of fatal cardiac arrythmias, but it is an incompletely understood phenomenon and difficult to predict. Cardiac calcium levels can be modeled as a system of partial differential equations linking the electrical

Inherent rhythm of smooth muscle cells in rat mesenteric arterioles: an eigensystem formulation [PDF]
Phys. Rev. E 93, 042415 (2016), 2016 On the basis of experimental data and mathematical equations in the literature, we remodel the ionic dynamics of smooth muscle cells (SMCs) as an eigensystem formulation, which is valid for investigating finite variations of variables from the equilibrium like in common experimental operations.

Calcium Signaling and Reactive Oxygen Species in Mitochondria
Circulation Research, 2018 In heart failure, alterations of Na+ and Ca2+ handling, energetic deficit, and oxidative stress in cardiac myocytes are important pathophysiological hallmarks. Mitochondria are central to these processes because they are the main source for ATP, but also

Intracellular calcium signaling [PDF]
Journal of Cell Science, 2002 In excitable cells, the major pathway for Ca2+ influx is via highly Ca2+-selective voltage-gated Ca2+ channels (VGCC). The original alphabetical nomenclature was replaced recently with standard numerical nomenclature: Cav1.1-1.4, Cav2.1-2.3, Cav3.1-3.3.

Molecular Players of EF-hand Containing Calcium Signaling Event in Plants
International Journal of Molecular Sciences, 2019 Ca2+ is a universal second messenger that plays a pivotal role in diverse signaling mechanisms in almost all life forms. Since the evolution of life from an aquatic to a terrestrial environment, Ca2+ signaling systems have expanded and diversified ...

Fundamentals of Cellular Calcium Signaling: A Primer.
Cold Spring Harbor Perspectives in Biology, 2019 Ionized calcium (Ca2+) is the most versatile cellular messenger. All cells use Ca2+ signals to regulate their activities in response to extrinsic and intrinsic stimuli.
