A resonator includes a CMOS substrate having a first electrode and a second electrode. The present invention also includes methods to obtain such proteins, nucleic acid molecules, antibodies, and inhibitory compounds. During capture of video by video capture devices, the FMC may be introduced into the captured video. Another AV-fistula includes a valved reservoir that receives a fluid agent from a hemodialysis needle while moving the needle into or from the fistula; the agent leaks from the reservoir into the fistula lumen. The locking mechanism is operative to releasibly secure the steering column in a selected position of adjustment.
