Purification and characterization of functional human paraoxonase-1 expressed in Trichoplusia ni larvae.

Human serum paraoxonase-1 (HuPON1) is difficult to either purify from plasma or functionally express in high yield from recombinant sources. Here, we describe the characterization of functional HuPON1 expressed and purified from Trichoplusia ni (T. ni) larvae infected with an orally active form of baculovirus.

[The use of polypropylene-polyester prostheses in cranioplasty].

The polypropylene-polyester prostheses were investigated in respect of their usefulness in cranioplasty. Experiments were performed upon 2 to 10 years old mongrels. It was stated that polypropylene-polyester prostheses did not produce any general reactions.

[Experimental allo-paratopic heart transplantation in dogs as a biological bypass of the left ventricle].

1. The authors' model of paratopic cardiac replacement by means of a branched Dacron prosthesis is considered a simple method for left-heart replacement. 2.
