متن کاملA technique to produce a mirror-image wax pattern of an ear using rapid prototyping technology.
This article describes the use of computer-aided techniques to produce a wax pattern of a missing ear. A 3-dimensional (3-D) computer model of a conventional cast from a patient was obtained using an optical surface capture device (scanner). The 3-D computer model was inverted, using computer-aided design software. A physical thermoplastic (wax) pattern of the inverted 3-D cast was produced usi...
متن کاملRemoval of inhibitor ( s ) of the polymerase chain reaction from formalin fixed , paraffin wax embedded tissues
A problem associated with use of the polymerase chain reaction to amplify specific DNA fragments from formalin fixed, paraffin wax embedded tissues is the not infrequent failure of amplification. One possible reason for this could be the presence of inhibitor(s), which interfere with the activity of the reaction. It has been shown that such inhibitor(s) exist when amplifying the human fl globin...
