Objective To develop an approach for a rapid extraction of genomic DNA fragments from serum.Methods Serum specimen from human was processed using high temperature denaturation and was centrifuged, then using various primer sets to amplify the DNA fragment extracted, so as to verify the efficiency of this DNA extraction method.Results The templates preparing from this DNA extraction method were able to guarantee the amplification of fragments shorter than 400 base pairs.Conclusion This method is simple, rapid and inexpensive.These genomic DNA fragment extracted can be utilized to amplify definite DNA template for polymerase chain reaction.

A digital beamformer in medical ultrasound imaging systems conventionally requires that the returning signals received by transducers are sampled at a rate significantly higher than the Nyquist rate. This paper presents a digital beamformer that employs zero padding followed by digital interpolation filtering to achieve vernier beamformer delays. The experimental results show that the digital interpolation beamformer can greatly decrease the complexity of A/D converter circuitry.
