Calcium (Ca 2+) and pH gradients are well expressed, and exhibit oscillations (Hepler et al., ). Of particular note, recent work reveals that an increase in the alkaline band, which resides in the clear zone near the cortical actin fringe, occurs in anticipation of an increase in growth (Lovy-Wheeler et al., ).

Calcium encoding (also referred to as Ca 2+ encoding or calcium information processing) is an intracellular signaling pathway used by many cells to transfer, process and encode external information detected by the cell. In cell physiology, external information is often converted into intracellular calcium concept of calcium encoding explains how Ca 2+ ions act as intracellular.

book. Abstract. Free Ca 2+ ions are among the half dozen or so small ions or molecules whose changing patterns within cells is in immediate control of their growth, development, behavior, and death. This chapter focuses on the role of free Ca 2+ in activating eggs and in the development of pattern.

Abstract. From beginning of the life to final moment of the life, Ca 2+ functions as an important signaling messenger. The intracellular Ca 2+ concentration, [Ca 2+] Calcium waves, in resting cells is normally maintained at around nM with a very steep ∼20, times concentration gradient of Ca 2+ between extracellular and intracellular compartments.

Ca 2+ signals in the form of time-dependent. 1. Introduction. A wide diversity of cell types can communicate with their neighbors by means of an intercellular calcium (Ca 2+) wave, i.e. the propagation of an increase in intracellular Ca 2+ concentration from cell to cell 1, ellular Ca 2+ waves can be initiated by a focal mechanical, electrical, or hormonal stimulus, and by propagating to numerous adjacent cells, may serve to.

Ciba Foundation Symposium ‐ Calcium Waves, Gradients and Oscillations: Calcium Waves, Gradients and Oscillations: Ciba Foundation Symposium First published: 28 September About this Book. The book \Oscillations and waves" is an account of one semester course, PHYSICS-I, given by the authors for the last three years at IIT, Kharagpur.

The book is targeted at the rst year undergraduate science and engineering students. Starting with oscillations in general, the book moves to interference and di raction phenomena of waves and. Intercellular calcium waves occur in diverse cells.

Those that are induced by mechanical stimulation have been extensively investigated in epithelial and glial cells. Mechanical stimulation of an individual cell initiates an increase in the intracellular free calcium concentration, [Ca 2+.

Bock and K. Ackrill), John Wiley & Sons, Ltd., Chichester, UK. doi: /ch   Intracellular Ca 2+ oscillations and waves are commonly observed both in excitable cells, including neurons, and in non-excitable cells.

Current attempts to describe and explain these complex intracellular signals suggest that the oscillations are the result of a highly regulated mechanism, the details of which vary among different cells. Oscillations in the cytosolic free Ca 2+ concentration ([Ca 2+] i) have been described in a variety of some cases, [Ca 2+] i oscillations reflect cycles of membrane depolarization and voltage‐dependent Ca 2+ entry.

In others, they are caused by periodic Ca 2+ uptake and release by internal stores, with little immediate requirement for external Ca 2+.

Calcium ions play an important role in a variety of cellular functions that impact nearly all aspects of cellular life. In fact, the calcium signal is one of the most versatile and universal signaling agents of the human body that controls almost everything we do – Ca 2+ ions contribute to egg activation upon fertilization, muscle contraction, enzyme secretion, neurotransmitter release, how.

1. The history of Ca 2+ oscillations. The first piece in the calcium (Ca 2+) signalling jigsaw puzzle was laid by Sydney Ringer more than a century ago, inwhen he discovered that hearts contracted in London tap water but failed to do so in distilled water.Since then thousands of publications have reported Ca 2+ signals in various cell types.

Cytosolic Ca 2+ signals appear in. In book: Ciba Foundation Symposium - Calcium Waves, Gradients and Oscillations (pp - ). Variable kinetics in the development of the calcium wave will result.

Because a number of channels must open within the vicinity of each other and within a certain time period for calcium-wave initiation, a lag period may also be detected. Lag periods may be common when IP 3 concentrations are low.

One of the more popular of the standard models underlying Ca 2+ oscillations between the ER and the cytosol is the biophysical De Young Keizer (DYK) model based around a detailed description of the dynamics for IP 3 receptors (IP 3 Rs).

It is believed to be the first model that explains oscillations on the basis of only the IP 3 R/channel and a single Ca 2+ pool. Sneyd J, Kalachev LV. A profile analysis of propagating calcium waves. Cell Calcium. Apr; 15 (4)– Sneyd J, Keizer J, Sanderson MJ.

Oscillations in the tip-focused Ca 2+ gradient correlate with growth rate in pollen tubes (see below). In guard cells, Ca 2+-induced oscillations can be induced by treatments such as changes in external [Ca 2+] and ABA (McAinsh et al., ; Staxen et al., ).

Velocity, amplitude, and efficacy of calcium wave spread. Calcium waves between cultures of IndoAM loaded astrocytes were evoked by mechanical stimulation of one cell in the confocal field ( × μm; 21, μm 2) using a glass pipette with a 1–2 μm outer velocities of calcium waves were calculated as the distance (μm) between the stimulated and the non-stimulated.

Furthermore, during the influx of Ca(2+) large and steep concentration gradients are predicted between the cytosol and the submicroscopically narrow subsarcolemmal space.

In addition, the computations revealed that, despite its low Ca(2+) affinity, ATP acts as a significant buffer and carrier for Ca(2+), even at the modest elevations of [Ca(2. Calcium Oscillations Physiological Mechanisms The resting state.

At rest, the concentration of calcium in the cell cytoplasm is low, around 30 nM, while outside the cell, and in the internal compartments such as the endoplasmic reticulum (ER), sarcoplasmic reticulum (SR) and mitochondria it is orders of magnitude higher.

These concentration gradients are maintained in part by calcium .Calcium ions participate in a multiplicity of physiological and pathological functions.

Among the most intensely studied, and the major focus of this article, is the role of Ca 2+ as a cellular signal. Elevations in cytoplasmic Ca 2+ mediate a plethora of cellular responses, ranging from extremely rapid events (muscle contraction, neurosecretion), to slower more subtle responses (cell division.
