Intracellular Ca2+ is released from intracellular stores in the endoplasmic reticulum (ER) in response to the second messenger inositol (1,4,5) trisphosphate (InsP3) [1,2]. Then, a poorly understood cellular mechanism, termed capacitative Ca2+ entry, is activated [3,4]; this permits Ca2+ to enter cells through Ca(2+)-selective Ca(2+)-release-activated ion(More)
Liesagang-like rings (LR) are periodic structures with equally spaced radial striations formed by a process that involves diffusion, nucleation, flocculation or precipitation, and supersaturation. Being more common in vitro, on rare occasions also reported in vivo in association with inflammatory or cystic lesions and confused with parasites or(More)
