Cytosolic calcium oscillation signaling in guard cell
Plant Science, 2003 Abstract Calcium signaling has been established to play a very important role in stomatal movements. More and more attentions have now been focused on cytosolic calcium ([Ca2+]cyt) oscillation in guard cell. It is still not clear how [Ca2+]cyt oscillation occurs and how it is decoded.

Adenylate cyclase activity oscillations as signals for cell aggregation in Dictyostelium discoideum
Nature, 1977 As well as acting as a chemotactic factor1 cyclic AMP stimulates cells of Dictyostelium discoideum to differentiate after the end of growth into aggregation-competent cells. These differentiation signals have a temporal pattern : pulses are efficient signals, whereas continuous administration of cyclic AMP may even have an adverse effect2,3.

pH oscillations in cell suspensions of Dictyostelium discoideum: Their relation to cyclic-amp signals [PDF]
Journal of Cell Science, 1978 ABSTRACT Cells of Dictyostelium discoideum known to release cyclic AMP (cAMP) rhythmically in the form of pulses, change with the same period of about 8 min the pH of their medium. The pH is used here as an indicator to investigate the effect of externally added cAMP pulses on the oscillations.

Role of mitochondria in Ca2+ oscillations and shape of Ca2+ signals in pancreatic acinar cells
Biochemical Pharmacology, 2002 We studied the role of mitochondria in Ca(2+) signals in fura-2 loaded exocrine pancreatic acinar cells. Mitochondrial depolarization in response to carbonylcyanide-p-tryfluoromethoxyphenyl hydrazone or rotenone (assessed by confocal microscopy using rhodamine-123) induced a partial but statistically significant reduction in the decay of Ca(2+) signals

Cell Calcium, 1991 Receptor-activated cytoplasmic Ca2+ oscillations have been investigated using both single cell microfluorometry and voltage-clamp recording of Ca(2+)-dependent Cl- current in single internally perfused acinar cells. In these cells there is direct experimental evidence showing that the ACh-evoked [Ca2+]i fluctuations are due to an inositol trisphosphate-

Journal of Basic and Clinical Physiology and Pharmacology, 1999 We studied effects of heat acclimation (HA) and acute heat stress (HS) on Ca2+ signal oscillations following supramaximal carbamyl-choline (CCh) stimulation, using HSY cell line as a model. In the control cells, oscillations decreased their amplitude with time.

Journal of Neurophysiology, 2006 Fast synaptic transmission between olfactory receptor neurons and mitral cells (MCs) is mediated through AMPA and NMDA ionotropic glutamate receptors. MCs also express high levels of metabotropic glutamate receptor 1 (mGluR1) whose functional significance is less understood.
