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.
Interlocking signals in the US represent the UK controlled signal; i.e. one that is controlled from a signal tower (cabin in UK) or any sort of control room. Interlocking signals offer a great variety of signal displays and commands which can be confusing.nterlocking signals in the US represent the UK controlled signal; i.e. one that is controlled from a signal tower (cabin in UK) or any sort of control room.
