Synthetic peptide analogs of chemokines are designed to include the N- and C-terminal portions of the corresponding naturally occurring chemokine. Flexible traces form datasignal lines to contacts on the central region. A reservoir is connected to a reservoir port in the rebreathing line. The wireless transceiver converts the serial data signals received from the host adapter into outgoing wireless signals for broadcast to the target system and incoming wireless signals received from the target system into the serial data signals for transmission to the host adapter. The method further comprises dynamically indicating the lowest price in which a transaction was made in the current time window, highest price in which a transaction was made in the current time window, and price of latest transaction.
