Oral rehydration therapy (ORT) is a type of fluid replacement used to prevent and treat dehydration, especially due to diarrhea. [1] It involves drinking water with modest amounts of sugar and salts, specifically sodium and potassium. [1]
Generally, the source of the constituent ions is a mixture of sodium chloride (NaCl), sodium lactate (CH 3 CH(OH)CO 2 Na), calcium chloride (CaCl 2), and potassium chloride (KCl), dissolved into distilled water. Ringer's solution has the same constituents without the sodium lactate, though sometimes it may also include magnesium chloride (MgCl ...
Top view of a potassium channel with potassium ions (purple) moving through the pore (in the center). ( PDB : 1BL8 ) Potassium channels have a tetrameric structure in which four identical protein subunits associate to form a fourfold symmetric ( C 4 ) complex arranged around a central ion conducting pore (i.e., a homotetramer).
Calcium-activated potassium channels are potassium channels gated by calcium, [1] or that are structurally or phylogenetically related to calcium gated channels. They were first discovered in 1958 by Gardos [who?] who saw that calcium levels inside of a cell could affect the permeability of potassium through that cell membrane. Then in 1970 ...
Potassium phosphate is a generic term for the salts of potassium and phosphate ions including: [1] Monopotassium phosphate (KH 2 PO 4) (Molar mass approx: 136 g/mol) Dipotassium phosphate (K 2 HPO 4) (Molar mass approx: 174 g/mol) Tripotassium phosphate (K 3 PO 4) (Molar mass approx: 212.27 g/mol) As food additives, potassium phosphates have ...
There are many different ways to prepare PBS solutions, common ones are Dulbecco's phosphate-buffered saline (DPBS) [2] and the Cold Spring Harbor protocol. [3] Some formulations of DPBS do not contain potassium and magnesium, while other ones contain calcium and/or magnesium (depending on whether or not the buffer is used on live or fixed tissue: the latter does not require CaCl 2 or MgCl 2).
