Figure 9

Local events such as microbleeding in the joints are trigger factors for IL-6 amplifier activation, which causes arthritis in aged F759 mice that have an excess number of Th17 cells in the blood stream.

The Pathological and Physiological Roles of IL-6 Amplifier Activation

Int J Biol Sci. 2012;8(9):1267-1280.
FIGURE 2

Amplifier Setup. Amplifier 1 (Red, SB_Dr) measures EEG_DrDr and EEG_PgDr while referenced (REF_Dr) and grounded (GND_Dr) to Dr electrodes. Amplifier 2 (Blue, SB_Pg) measures EEG_DrPg, EEG_PgPg, EOG_PgPg, LEMG_PgPg and REMG_PgPg while referenced (REF_Pg) and grounded (GND_Pg) to Pg electrodes. A trigger signal is exchanged between the two amplifiers to synchronize the sampling.

FIGURE 10.Full Piezoelectric Setup Schematic:

The MRE control PC generates a TTL trigger signal to drive the piezoelectric actuator through the amplifier and the function generator via the external trigger input port.

Design, Construction, and Implementation of an MR Elastography (MRE) Actuator for Research Purposes

Curr Protoc. ;2(3):e379-e379.
Fig. 9

Circuit simulation results with a timing diagram that shows the Rx enable, which powers up the receiver circuitry, Tx trigger signal (delayed Clk input) and the amplifier current consumption. Note that the type of the receive amplifier that is used in this timing simulation is the resistive-feedback TIA design.
