1.   This then, this depolarization then allows the opening of voltage gated calcium channels, the calcium inside rises and contraction occurs.

2.   The water soluble component, the I P three, the product of this, diffuses to the endoplasmic reticulum where it gates open a calcium channel.

3.   But no one yet knows how it malfunctions, nor how a defective calcium channel could cause low levels of potassium in the blood.

4.   Derived from sea snail venom, it is designed to block calcium channels in nerve cells of the spine, interrupting the flow of pain signals to the brain.

5.   Guinea pigs that make antibodies to calcium channels accumulate calcium in their nerve cells, which poisons the cells and makes the animals develop a disease like ALS.

6.   It extended earlier findings by focusing on the importance of the amount of calcium channel blockers prescribed for a patient.

7.   Many ALS patients have antibodies to calcium channels.

8.   Most of the calcium channel blockers used were of the older, fast-acting variety, the researchers said.

9.   Patients worried about calcium channel blockers also have been calling cardiologists at other hospitals.

10.   This chromosome codes for a component of a calcium channel in neural membranes.
