Abstract: The present invention relates to novel NADPH oxidase proteins, or Nox, the use thereof, the method of preparation thereof and the method for identification thereof.

Abstract: A NADPH oxidase (Nox) protein includes a domain including 3 to 7 transmembrane helices, and an amino acid sequence including at least 2 bis-histidyl motifs, wherein each of the bis-histidyl motifs consists of 2 histidine residues separated by 12, 13 or 14 amino acid residues. The Nox protein may be produced by a method that includes solubilizing a solution of cells expressing the Nox protein using a detergent from the maltoside family to suspend the Nox protein in the solution.

Abstract: The present invention relates to novel NADPH oxidase, or Nox, proteins, to the use thereof, to a method for preparing same and to a method for identifying same.

Abstract: The object of the invention is a process for molding an optical element such as a lens (2). According to the invention, the element is obtained by a reaction injection molding process comprising the steps of mixing at least two polymerizing reactants and forcing the obtained reacting mixture by an injection duct (5) for filling under pressure a scaled mold cavity (4) having an entry side (43) provided with a casting opening (42) and an evacuation side (44) and providing a laminated flow of mixture in a spout (6) having a progressive enlarging transversal section between the outlet opening (52) of the injection duct (5) and the casting opening (42) of the mold cavity (4), for avoiding any turbulent area in said laminated flow, said evacuation side (44) being provided with means (45) for evacuating air contained in the mixture during mold filling. The invention also covers the molding installation adapted for using such a process.

Abstract: The solid catalytic component according to the invention is obtained bya) treatment of a catalytic component support with ZrCl.sub.4 or HfCl.sub.4 in the gas phase, followed by ab) treatment with a solution or suspension of a compound capable of grafting a group containing the cycloalkadienyl skeleton to the Zr or Hf contained in the support. Polymerization of olefins in the presence of such a catalytic component results in polymers with low polydispersities, which polymers are obtained with high productivities.
