In salty environments, the Na+ gradient possibly represents an alternative energy source for the influx of Pi[ 54].
The TRITC-dextran content of the phagosome was diluted by the fusion event, indicating that the source of the fluid influx was at least partly unlabeled (Figure 10 and Movie S12).
Although dietary iron intake is the major source of iron influx in the body, the primary homeostatic mechanism for maintaining iron balance is the absorptive efficiency of the small intestine [ 7].
(i) that calcium is the primary signal for synaptic plasticity, (ii) that the dominant source of calcium influx to the postsynaptic cell is through NMDARs, and (iii) that dendritic back-propagating action potentials (BPAPs) contributing to STDP have a slow "after-depolarizing" tail component.
Here, we show that the recently identified Orai1 protein represents the major molecular component of endogenous store-operated Ca2+ entry (SOCE) in human prostate cancer (PCa) cells, and constitutes the principal source of Ca2+ influx used by the cell to trigger apoptosis.
The source of calcium influx in our spine model is through the NMDA receptors, and calcium is removed by calcium pumps, binding to a calcium buffer, and diffusion through the spine neck.
Solar cells, in general, perform under light source of solar influx, while the heat energy of solar radiation remains unutilized.
Some do not explicitly model stem cells but include them as a source of cellular influx into the modeled differentiation stages of hematopoiesis [ 8- 10].
Results suggest that bulk Na+ ion diffusivity in cytoplasm is fast enough to produce a near-uniform rise in releasable Ca2+ (despite slow intra-SR Ca2+ ion diffusion), and therefore a more coordinated global rise in CaT amplitude, even when the source of Na+ influx is highly localized.
In the case of Ca2+ oscillations one candidate for the source of the pertubations is Ca2+ influx [24].
