The present invention discloses compositions and methods to measure an amount of Anti-Mullerian Hormone in a sample, including a mammalian sample such as a primate, rodent, equine, or bovine sample. The sight mount is fitted with integrated and split rings and two top ring halves are arranged to attach a riflescope. The biasing member is compressible to allow the outer member to move into a second position as the outer member is moved through an opening in the workpiece. The patient interface may be adapted to interface a gas ventilation system to facilitate a rapid conversion from gas to liquid ventilation.
