The five lei banknote is one of the circulating denomination of the Romanian leu.It is the same size as the 10 Euro banknote.. The main color of the banknote is purple. It pictures, on the obverse composer and violinist George Enescu, and on the reverse the Romanian Athenaeum, headquarters of the George Enescu Philharmonic Orchestra, a piano, and a line from his opera, Œdipe.
A 500 lei coin and the 2,000 lei note shown above were made in order to celebrate the 1999 total solar eclipse. Whereas the 500 lei coin is currently very rare, becoming a prized collector's item, the 2,000 lei note was quite popular, being taken out of circulation in 2004 (a long time after the 1,000 and 5,000 lei bills were replaced by coins).
Ion channels are located within the membrane of all excitable cells, [ 3] and of many intracellular organelles. They are often described as narrow, water-filled tunnels that allow only ions of a certain size and/or charge to pass through. This characteristic is called selective permeability.

Voltage-gated sodium channels ( VGSCs ), also known as voltage-dependent sodium channels ( VDSCs ), are a group of voltage-gated ion channels found in the membrane of excitable cells ( e.g., muscle, glial cells, neurons, etc.) with a permeability to the sodium ion Na +. They are the main channels involved in action potential of excitable cells.
Voltage-gated ion channels are a class of transmembrane proteins that form ion channels that are activated by changes in a cell's electrical membrane potential near the channel. The membrane potential alters the conformation of the channel proteins, regulating their opening and closing. Cell membranes are generally impermeable to ions, thus ...
The following is a list of stations that are affiliated with Ion Plus, a television network in the United States owned by Ion Media Networks. The network was originally in operation from 2007 to 2021 with a total of 65 affiliates, the vast majority of which were owned by its corporate parent. [ 1][ 2][ 3] The network returned to over-the-air ...
Channelopathies are a group of diseases caused by the dysfunction of ion channel subunits or their interacting proteins. These diseases can be inherited or acquired by other disorders, drugs, or toxins. Mutations in genes encoding ion channels, which impair channel function, are the most common cause of channelopathies. [ 1]
