Abstract: A power steering system for a motor vehicle, including: a steering module including a steering casing inside which a steering rack is slidably mounted; and an assist module including a reducer casing fastened on a dome of the steering casing and inside which a gear reducer is mounted, including a worm screw driven by an assist motor and which meshes on a worm wheel linked in rotation to an output shaft with a pinion engaged with the steering rack and rotatably mounted in a rolling bearing carried by a bearing on the reducer casing, and a blocking nut is screwed inside the bearing in abutment against the rolling bearing, this nut being disposed facing an inner face of the dome from which at least one end stop protrudes opposite to the nut at a distance (DJ) allowing the nut to stop in the case of loosening.

Abstract: The invention provides recombinant DNA molecules which code for polypeptides that exhibit the antigenicity of a P14 allergen of birch Betula verrucosa and other plants of the order Fagales, and for polypeptides comprising at least one epitope thereof, as well as nucleic acids which under stringent conditions hybridize with such DNA sequences or are derivable from such sequences by degeneracy of the genetic code. A method is provided that permits purification of P14 allergens or cross reactive allergens by means of binding to poly(L-proline). In addition, methods are described for making the proteins and polypeptides coded by these DNA molecules and their use in the diagnosis or therapy of diseases.

Abstract: The gene for the outer membrane protein lipoprotein I (OMPI) of Pseudomonas aeruginosa ATCC 33354 has been sequenced, and the amino acid sequence has been deduced. This makes it possible to obtain this protein and immunogenic part-sequences thereof in the quantity and purity necessary for use for the preparation of vaccines.
