A cell embedded within the mineralised matrix of bone. Osteocytes are derived from former osteoblasts and are responsible for intra-skeletal sensing and signalling. 

The oscillation of membrane current or membrane potential is well-known to occur in biomembranes of neurons and heart cells, and a great number of experimental and theoretical studies on oscillations in biomembranes as well as artificial membranes [1,2] have been carried out from the viewpoint of their biological importance. The oscillation in the membrane system is also related to the sensing and signal transmission of taste and olfaction. Artificial oscillation systems with high sensitivity and selectivity have been pursued in order to develop new sensors [3-8].

Adaptation to changes in osmotic pressure involves sensing and signaling pathways that have been partially elucidated for E. colip and yeasts.1/q Major changes in structure and metabolism may result. For example, in E. coli the outer membrane porin OmpF (Fig. 8-20) is replaced by OmpC (osmoporin), which has a smaller pore.1... 

For example, mice deficient in the mGluRl protein have severe problems with motor coordination and learning.681682 Metabotropic glutamate receptors may participate in calcium sensing and signaling.683 684...

Within the context of supramolecular devices, re-emission of the radiation by luminescence is of interest in sensing and signalling applications, while chemical reactions are of interest in applications such as molecular switches and photocatalysis. Strictly speaking absorption and re-emission type processes are termed molecular photophysics while light-induced chemical reactions or chemical processes are termed photochemistry .

From these studies, it is now possible to construct a generalized framework or working hypothesis for how hypoxia-tolerant cells respond to oxygen lack (figure 3.18). During the very early acute phases, a poorly understood hypoxia-sensing and signal transduction system orchestrates a series of molecular hypoxia defense processes, which include ...
