which facilitates the flow of potassium ions out of cells. Using advanced structural imaging and computer modeling techniques, the researchers confirmed that BK channels can stop their ion flow via a ...

Researchers have confirmed that mammalian BK ion channels regulate themselves using a “ball-and-chain” mechanism. A recent ...

Medically reviewed by Chika Anekwe, MD A potassium blood test is used to measure the amount of potassium in your blood. It is ...

A new study has unveiled a precise picture of how an ion channel found in most mammalian cells regulates its own function with a "ball-and-chain ...

Many nutrients, such as calcium and magnesium, may be supplied to plants solely from reserves held in the soil. Others like potassium are added regularly to soils as fertilizer for the purpose of ...

those that do not should reveal themselves through correlations among the levels of various ions. The aim here is to consider correlations among sodium, potassium and magnesium. There is known to ...

A new study has unveiled a precise picture of how an ion channel found in most mammalian cells regulates its own function with a 'ball-and-chain' channel-plugging mechanism. The findings boost the ...

The BK ion channel pictured above forms a small pathway in the cell membrane (dark gray) that allows potassium ions (purple) to move in and out of the cell. This channel can stop the flow of ions ...
