Abstract: Nouveaux anticorps bactéricides dirigés contre le sérogroupe B ("MenB") neisseria meningitidis. Lesdits anticorps soit ne réagissent pas de manière croisée, soit réagissent de manière croisée au minimum, avec l'acide polysialique du tissu hôte et présentent un risque minimal d'activité auto-immune. Les anticorps sont utilisés pour l'identification des mimétiques moléculaires d'épitopes uniques découverts sur MenB ou E. coli K1. Sont décrits des exemples desdits mimétiques de peptides qui élicitent un anticorps sérique capable d'activer la bactériolyse sous la dépendance du complément. Les compositions contenant lesdits mimétiques peuvent être utilisées pour la prévention de MenB ou E. coli K1 sans risque d'évocation d'auto-anticorps.

Abstract: La présente invention concerne une gaine (20) jetable, stérilisée, destinée à être utilisée sur une sonde de cryochirurgie (10) Joule-Thomson à boucle fermée, et la combinaison de la gaine (20) jetable et de la sonde (10). La gaine (20) est glissée sur la sonde (10) et sépare ainsi la sonde (10) de l'environnement. La gaine est munie d'une poignée (22) qui s'emboîte sur le manche (12) de la sonde (10), et d'une enveloppe extensible (23) qui peut être étirée dans le sens longitudinal de sorte qu'elle recouvre le tube (18) qui est fixé au manche (12). La gaine (20) est dotée d'un cathéter (24) creux à plusieurs lumières conçu et dimensionné pour s'ajuster de manière serrée sur la canule (14) de la sonde (10). Le cathéter (24) n'est pas thermiquement conducteur, il empêche ainsi le transfert de chaleur de l'ambiant vers le mélange gazeux et le gel de tissus à des emplacements non souhaités. Un embout ou extrémité (26) thermiquement conducteur s'ajuste de manière serrée sur l'extrémité (16) froide de la sonde (12) et transfère efficacement la chaleur du tissu cible à l'extrémité (16) froide qui, à son tour, transfert la chaleur au mélange gazeux détendu. On peut fixer plusieurs types d'instruments auxiliaires sur le cathéter (24) ou l'extrémité conductrice (16), tel qu'un capteur de température, un organe chauffant, un transducteur à ultrasons, ou un élément optique d'un système de visée, d'éclairage ou laser. Les raccords entre les instruments se trouvant à proximité de l'extrémité distale du cathéter (24) et la sonde (10) se font par l'intermédiaire d'une pluralité de lumières passant de manière longitudinale à travers la paroi du cathéter (24).

Abstract: The invention concerns a disposable two-compartment atomizer for discharging two successive part-charges as a spray, said atomizer comprising on a base body (12) a projecting nose-adapter (13) with a nozzle (14), actuating shoulders (35) where two fingers can rest, and an actuating part which can be pressed into the base body and has an actuating sleeve (25) and a medium store (20) held therein. A hollow needle (17) can penetrate the closure piston-stopper (21) of said medium store (20). A ring (28) is mounted on the actuating sleeve (25) by means of spokes (29) and with predetermined breakage points (30), the ring breaking when the atomizer is used for the first time and a minimum actuation pressure is maintained. The spokes strike a stop and thus delimit the first partial stroke. By rotating the actuating sleeve, the actuating section is moved into the starting position for the second stroke step, wherein intermediate webs in the form of material bridges are broken out. The second partial stroke can then also be carried out with a minimum actuating force being maintained.
