It is the most inexpensive, compact, and widely used type of atomic clock, used to control the frequency of television stations, cell phone base stations, in test equipment, and global navigation satellite systems like GPS.SK channel: SK channels (Small conductance calcium-activated potassium channels) are a subfamily of Ca2+-activated K+ channels. They are so called because of their small single channel conductance in the order of 10 pS.Calcium signaling: Calcium ions are important for cellular signalling, as once they enter the cytosol of the cytoplasm they exert allosteric regulatory effects on many enzymes and proteins. Calcium can act in signal transduction resulting from activation of ion channels or as a second messenger caused by indirect signal transduction pathways such as G protein-coupled receptors.Ventricular action potentialHyperchloremiaBarium orthotitanate: Barium orthotitanate is the inorganic compound with the chemical formula Ba2TiO4. It is a colourless solid that is of interest because of its relationship to barium titanate, a useful electroceramic.Potassium cyanideCaesium bromideTranscellular transport: Transcellular transport involves the transportation of solutes by a cell through a cell. One classic example is the movement of glucose from the intestinal lumen to extracellular fluid by epithelial cells.PolyelectrolyteBurst kinetics: Burst kinetics is a form of enzyme kinetics that refers to an initial high velocity of enzymatic turnover when adding enzyme to substrate. This initial period of high velocity product formation is referred to as the "Burst Phase".Stretch-activated ion channel: Stretch-activated or stretch-gated ion channels are ion channels which open their pores in response to mechanical deformation of a neuron's plasma membrane.

In contrast, embryo selection takes place after fertilization.Aldosterone escape: In physiology, aldosterone escape is a term that has been used to refer to two distinct phenomena involving aldosterone that are exactly opposite each other:Concentration effect: In the study of inhaled anesthetics, the concentration effect is the increase in the rate that the Fa(alveolar concentration)/Fi(inspired concentration) ratio rises as the alveolar concentration of that gas is increased.
