Diffusion of material through gap junctions is stimulated by high intracellular sodium (Gandhi et al., 2009b), extracellular glutamate, quisqualate and kainate (Enkvist and McCarthy, 1994), and elevated levels of extracellular K+ (Enkvist and McCarthy, 1994; De Pina-Betalou et al., 2001).
The mainstream appetite for such material has been stimulated by television, whose young, white constituency -- the glowing red center of the target demographic that studios are always aiming for -- has been steadily growing.
It was not until 1996, long after metal-based lasers were in wide use, that researchers were even able to confirm that it was possible for solid organic materials to be stimulated enough to emit laser light.
After a successful development of CNT and fullerene C60, various spherical fullerene-like configurations composed of inorganic non-carbon materials have been stimulated a great deal of interest [9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20].
A laser requires two things: a material that can be stimulated in some way to produce light and a "resonant cavity" that will ring with light waves of particular wavelengths much as an organ pipe will ring with sound waves of distinct frequencies.
In order to investigate immune function in sample material, PBMC cells are stimulated in vitro with αCD3/αCD28 mAb and with TLR2/1 ligand Pam3CSK4 (PandCys) and TLR4 ligand LPS in RPMI at 37°C in 5% CO2.
No. Writing is stimulating enough.
That early tension is stimulating.
