Abstract: The invention concerns a method for producing interconnection in a multilayer printed circuit. The latter comprising a stack of printed circuits, the method comprises the following steps which consists in: covering the metal interfaces (61, 62) with a component of a metal alloy, the metal interface (61) of a hole being covered with a first component (71) and the metal interface (62) of the element to be electrically connected to said hole being covered with a second components (72), said two metal components (71, 72) being contacted when pressure is exerted on the stack to form the multilayer printed circuit; heating (73) the assembly to produce diffusion of the metal components (71, 72) wherein the metal interfaces (61, 62) diffuse into the metal components, the diffusion temperature of said components being lower than the melting temperature of the metal compound (74) obtained after cooling and forming the electrical bond. The invention is, for example, applicable to digital circuits with high density of integration or for microwave circuits.

Abstract: La présente invention concerne des gènes isolés provenant de Beta vulgaris, la betterave à sucre, et étant impliqués dans des réponses aux situations de stress. Lesdits gènes ont été isolés d'une bibliothèque d'ADNc de betterave à sucre soumise à un criblage dans le cadre d'une procédure de sélection fonctionnelle avec des cellules de levure transformées qui ont réussi à se développer dans un milieu de sélection avec des concentrations en sel élevées. Ces gènes ont ensuite été séquencés puis caractérisés. L'un des gènes est une .alpha.-subunite de caséine kinase de betterave à sucre, un autre est une dihydroorotase de betterave à sucre, un autre est un facteur 1A d'initiation de translation de betterave à sucre, et les deux autres sont d'un type protéique inconnu. Tous ces gènes végétaux isolés ont des fonctions d'activateurs de tolérance aux stress dans des cellules de levure, et sont de ce fait utiles pour conférer une tolérance aux stress à un organisme lorsqu'ils sont transfectés dans celui-ci. Plus particulièrement, ces gènes peuvent être utilisés pour produire des végétaux de culture résistant aux situations de stress telles que le stress osmotique causé par le sel, la sécheresse, le froid et le gel.

Abstract: It is intended to provide an expression system of a recombinant protein and a cell-free translation system with the use of a host wherein a target protein is surely incorporated into the stereo structure of chaperonin as a fused protein with a chaperonin subunit (namely, a molecular chaperonin of about 60 kDa, heat shock protein of 60 kDa or thermosome) to thereby inhibit the expression of toxicity of the target protein in the host, the formation of an enclosed matter, and digestion with a protease, thereby universally expressing any protein as a soluble protein. Namely, a process for producing a protein characterized by transcribing and translating a gene containing a gene encoding a chaperonin subunit and a gene encoding a target protein to thereby synthesize a fused protein in which the target protein is linked to the chaperonin subunit via a peptide bond.

Title: Variant integrin polypeptides and uses thereof
Inventor: LI RUI
IPC: C07K14/705
Filed: 2003-05-12
Abstract: Polypeptides comprising all or part of a variant integrin .alpha. subunit A domain and its flanking region are described. In solution or in membrane- associated form, the A domain polypeptides of the invention exists predominantly in a high affinity conformation. In the polypeptides of the invention, referred to as variant integrin polypeptides, a crucial isoleucin e or glutamic acid residue is altered. For example, the glutamic acid can be either deleted or replaced with different amino acids residue, e.g., glutamine, aspartic acid, or alanine. The variant integrin polypeptides of t he invention selectively impair binding or activation-dependent ligands, but no t independent ligands. They are useful in screening assays for the identification of molecules that enhance binding of variant polypeptides wit h impaired binding. In addition, they are useful in distinguishing between activation-dependent ligands and activation-independent ligands. They are al so useful for generating antibodies, e.g., monoclonal antibodies, which bind to the impaired form of an integrin. Some such antibodies recognize an epitope that is either not present or not accessible on an integrin that is in the high affinity conformation. The variant integrin polypeptides of the inventi on can be derived from any integrin .alpha. subunit that could be used therapeutically.
