Zinc is a vital micronutrient involved in many cellular processes: For example, in learning and memory processes, it plays a role that is not yet understood. By using nanoelectrochemical measurements, Swedish researchers have made progress toward understanding by demonstrating that zinc influences the release of messenger molecules. As reported in the journal Angewandte Chemie, zinc changes the number of messenger molecules stored in vesicles and the dynamics of their release from the cell.

When signals are transmitted by synapses, messenger molecules (neurotransmitters) are released from storage chambers (synaptic vesicles) into the synaptic cleft, where they are "recognized" by neighboring nerve cells. This release is based on exocytosis: The vesicle docks at the cell membrane, opens at the point of contact, releases part of its contents to the outside, closes, and separates from the plasma membrane so it can be refilled.

Treatment with zinc results in more messenger molecules being released.

    That was an interesting article about kidney stones. A good comparison between men's and women's different urine content levels, in contrast to who had stones and who didn't. It might help explain why men have a greater chance of getting stones (7% more chance during lifetime).

    It was interesting that women had more phosphatidylserine than men when they observed that control.

    I am curious what it was you thought about the impact of the phosphatidylserine content mentioned there.

    Maybe your input could help me study this topic further. Thanks for the input. If you get a chance, I wouldn't mind if you described the concern a little more.
