Calcium is unique among metals because its ions have a very large concentration gradient across the plasma membrane of all cells, from 10 â3 M Ca 2+ outside, to 10 â7 M Ca 2+ inside.

A relapse or recidivism is a recurrence of a past (typically medical) condition. For example, MS or malaria often exhibit peaks of activity and sometimes long periods of dormancy. Relapse, in relation to drug abuse, is resuming the use of a drug or a chemical substance after one or more periods of abstinence.
