    Abstract: A method of detecting epithelial cancer is described that includes the steps of: (a) determining the level of beta defensin 3 (BD-3) and beta defensin 2 (BD-2) in a suspect sample obtained from a subject; (b) comparing the level of BD-3 to BD-2 determined in the suspect sample to obtain a suspect BD-3/BD-2 ratio, (c) comparing the suspect BD-3/BD-2 ratio to a healthy BD-3/BD-2 ratio to obtain a diagnostic BD-3/BD-2 ratio; and (d) characterizing the subject as having epithelial cancer if the diagnostic BD-3/BD-2 ratio is greater than 1. A microfluidic device for detecting epithelial cancer using the diagnostic BD-3/BD-2 ratio is also described.

    Abstract: A system for RF based frequency encoding utilizing a Bloch-Siegert shift, includes a controller, an RF encoding system, and an injection transformer simultaneous transmit and receive filter. The controller generates RF excitation pulses, RF based frequency encoding pulses, and a cancellation signal. The RF encoding system includes one or more RF coils configured to transmit the RF excitation pulses and RF based frequency encoding pulses, and to receive an MR signal from the subject where the MR signal includes a leakage signal induced by the RF based frequency encoding pulses. The injection transformer simultaneous transmit and receive filter is in signal communication with the controller and the RF encoding system. The injection transformer simultaneous transmit receive filter is configured to receive the cancellation signal, the MR signal including the leakage signal, and to cancel the leakage signal from the received MR signal to generate a filtered MR signal.
