This method involves the use of a small wick that is inserted through a tympanic membrane vent tube into the round window niche.
Next, a silicone vent tube Silverstein with an inner diameter of 1.42 mm and a 1-mm flange is inserted into the tympanostomy opening.
When the target area is free of blood and fluid, the MicroWick is inserted through the vent tube by placing its distal end into the round window niche (figures 3, 4).
Turner explains that he bought the stands last year - just before rehiring some workers who had inserted the old way for years and didn't want to change.
In contrast to the eight movements involved in opening, inserting, closing and removing a flat newspaper, he says, a supported upright bundle of newspapers able to slip forward and backward within a stand can be inserted in only four movements, then removed as one bundle.
While his crew "sure couldn't save any time" working with 50-copy bunches, Turner says, working with half that number would have been manageable and prevented "having to go back and count" copies once they were inserted.
A gene from the malariacausing organism has also been inserted into a vaccinia virus and shown to trigger antibody production when inoculated into laboratory animals.
Thus, the gene for hepatitis B surface antigen was inserted into the vaccinia virus to create a hepatitis-fighting vaccine; the anti-herpes vaccinia was constructed with the gene for a herpes surface molecule called glycoprotein D; and the influenza-vaccinia recombinant vaccine contains the gene for influenza hemagglutinin.
Paoletti has already inserted three different foreign genes into a single vaccinia virus.
