Abstract: Disclosed is a compressor having a plate rotatable about an axis of a rotary shaft and a piston connected to the plate. The plate causes the piston to reciprocate between a top dead center and a bottom dead center in accordance with the rotation movement of the plate. Cam surfaces are provided with the plate for actuating the piston. The cam surfaces have first portions for driving the piston toward the top dead center, and second portions for driving the piston toward the bottom dead center. Transmission members are interposed between the piston and the plate for transmitting the rotation movement of the plate to the piston. The first and second portions cause the transmission members to displace on the cam surfaces. At least one of the first and second portions are arranged to have a normal line extending obliquely to the axis of the rotary shaft for a constant contact between the transmission members and the one of the portions.

Abstract: A guiding structure (16, 18, 20, 22) of this component includes a core structure (18) extending up to coupling faces (8, 10). It is composed of at least three high-index layers (30, 34, 38) having refractive indices which are higher compared to the surrounding media (16, 32, 36, 20) in order to increase, in these layers, the power density of light having to undergo processing such as an amplitude modulation. These high-index layers have compositions enabling them to perform this treatment in response to an electrical excitation while still having thicknesses greater than those of quantum wells. These layers are separated by dilution layers (32, 36) having a lower refractive index and having greater thicknesses such that a single propagation mode of the light is guided by the guiding structure. This mode has a thickness suitable for coupling to an external optical element while at the same time confining most of the light power in the thickness of the core structure in order to promote the processing. <IMAGE>

Abstract: A method for the direct analysis of analyte indicative of marijuana exposure found in keratinized structures, e.g., hair, fingernails and toenails, which comprises preparing a mixture containing dithiothreitol or dithioerythritol, a protease suitable for the digestion of the keratin structure and a sample of the keratin structure; permitting the enzyme to at least substantially digest the sample of keratin structure to form a digest solution, followed by mixing the digest solution with a suspension of an ion exchange resin to remove an interfering, cross reacting substance naturally found in hair and finally subjecting the digest solution to analysis to determine the identity and amount of marijuana analyte in the keratin structure sample. To accelerate the method, cupric sulfate may be added to the mixture after degradation of the keratin sample in order to deactivate the activator. The enzyme may be a protease with papain, chymopapain, and proteinase K being preferred for use in the invention. Exemplary ion exchange resins useful in the method according to the invention are DEAE Sephadex (Diethylaminoethyl Sephadex) and DEAE Sepharose (Diethylaminoethyl Sepharose).

Abstract: L'invention concerne les effets de la suppression de l'expression de l'oncogène c-fos sur des cellules de mammifère résistantes aux médicaments ou aux rayonnements. On a isolé des cellules humaines de cancer des ovaires A2780S présentant une résistance à l'actinomycine D, et les cellules résultantes A2780AD ont présenté le phénotype MDR. Une ribozyme à tête de marteau conçue pour cliver l'ARN de fos cloné dans le plasmide pMAMneo a été transfectée dans des cellules A2780AD. L'induction de la ribozyme a pour résultat une expression réduite de c-fos, suivi de celle de mdr-1, c-jun et p53. L'inversion du phénotype MDR par la ribozyme anti-mdr a eu lieu quatre fois plus vite que celle induite par la ribozyme anti-fos. Ces études démontrent la prééminance de l'oncongène c-fos dans le maintien du phénotype résistant dans des cellules cancéreuses humaines. Par conséquent, la régulation négative de fos/jun rend les cellules cancéreuses résistantes plus sensibles à un traitement classique, c'est-à-dire, à l'aide d'agents et/ou de rayons chimiothérapeutiques contre le cancer.
