Once released, BNP binds to and activates the atrial natriuretic factor receptor NPRA, and to a lesser extent NPRB, in a fashion similar to atrial natriuretic peptide (ANP) but with 10-fold lower affinity.
The GTP layer for the control plane (GTP-C) tunnels signaling messages between GSNs in the GPRS backbone network.The GTP-C enables several procedures to be performed through the GPRS backbone network, including path management, tunnel management, location management, and mobility management.he GTP layer for the control plane (GTP-C) tunnels signaling messages between GSNs in the GPRS backbone network.
Pain messages travel along the peripheral nervous system until they reach the spinal cord. The gate control theory proposes that there are gates on the bundle of nerve fibers in the spinal cord between the peripheral nerves and the brain.These spinal nerve gates control the flow of pain messages from the peripheral nerves to the brain.ain messages may also be directed along a variety of pathways in the brain. 1  For instance, a fast pain message (A-delta fiber) is relayed by the spinal cord to specific locations in the brain, namely the thalamus and cerebral cortex.
