The region of an enzyme that interacts with its substrate to cause the enzymatic reaction.

Geological formations consisting of underground enclosures with access from the surface.

The number of CD4-POSITIVE T-LYMPHOCYTES per unit volume of BLOOD. Determination requires the use of a fluorescence-activated flow cytometer.
