Abstract: Molecular cloning and expression of a prostaglandin F2.alpha. receptor which is linked to the signal transduction pathways via guanine nucleotide binding regulatory (G) proteins and measured by, for example, cAMP, IP3 or intracellular calcium. By constructing cell tines that express a prostaglandin F2.alpha. receptor, the affinities and efficacies of agonist and antagonist drugs with the receptor can be assessed. A recombinant DNA construct includes a vector and a DNA fragment encoding a prostaglandin F2.alpha. receptor. A host cell is transformed with a recombinant DNA  construct, so that the DNA-fragment is expressed and a prostaglandin F2.alpha. receptor is produced. Suitable host system includes euk~tic and prokaryotic cells, especially mammalian cells such as rat or human. Additionally, for diagnostic purposes, antibodies ~  prostaglandin F2.alpha. receptor can be prepared by producing all or a portion of the receptor protein and injecting these into various types of mammals. Using the resulting antibodies, expression of an F2.alpha. receptor cDNA, i.e. receptor protein in tissue and cells can be measured.

Abstract: An apparatus for electronically controlling the flow of low pressure gas to a compressor and preventing backflow from the compressor, the apparatus including a housing in fluid communication with the compressor, where the housing has a chamber, a housing inlet for receiving a low pressure gas, and a housing discharge port for flowing the low pressure gas to the compressor and through which backflow gas flows from the compressor.  A valve member having a contact end is movable within the chamber along a predetermined path.  The apparatus also includes a drive for moving an actuator along an axis.          The actuator has an extension with an end adapted to abut the contact end of the valve member to thereby move the valve member along the path toward the housing inlet.  The valve member is movable along the path and away from the inlet, when the actuator is retracted, by the flow of low pressure gas through the inlet.  Upon compressor shutdown, the back pressure moves the valve member to a substantially occluding position relative to the inlet position to prevent backflow from flowing outward from the compressor.

Abstract: Méthodes et instruments que pourrait utiliser un chirurgien pour stabiliser un coeur palpitant au cours d'une intervention chirurgicale sur le coeur.  D'après cette invention, on introduit par une ouverture un instrument stabilisateur dans le thorax et on le met en contact avec le coeur palpitant.  En établissant ce contact du coeur avec cet instrument et en appliquant une pression stabilisatrice sur celui-ci, on supprime efficacement le mouvement du coeur dû à la contraction des muscles cardiaques, si bien que le coeur s'en trouve stabilisé et que le site de l'intervention chirurgicale bouge très peu, sinon même pas du tout.  Dans un cas typique, l'intervention comprend les étapes suivantes : le chirurgien met le coeur en contact avec l'instrument stabilisateur, évalue l'ampleur du mouvement du siège de l'anastomose et exerce une certaine pression sur l'instrument stabilisateur de manière à ce que les contractions du coeur palpitant n'entraînent qu'un minimum de déplacements additionnels du site de l'intervention chirurgicale.  En établissant l'instrument chirurgical dans une position où le mouvement du coeur palpitant est éliminé avec efficacité, le chirurgien est ainsi en mesure de stabiliser le coeur palpitant pendant toute la durée de l'intervention.  Cet instrument de stabilisation peut être fixé à un support rigide ou à un support semi-rigide que l'on immobilise mécaniquement, chimiquement ou par intervention humaine.  Pour certaines réalisations concrètes préférées, on fixe l'instrument de stabilisation à un support semi-rigide et on le rend rigide en employant une technique choisie parmi plusieurs autres possibles, de manière à consolider dans sa position l'instrument de stabilisation grâce à ce support et à se donner ainsi l'assurance que le coeur reste sensiblement immobile en cours d'intervention.

Abstract: A bi-static radar configuration measures the direct time-of-flight of a transmitted RF pulse and is capable of measuring this time-of-flight with a jitter on the order of about one pico-second, or about 0.01 inch of free space distance for an electromagnetic pulse over a range of about one to ten feet. A transmitter (53) transmits a sequence of electromagnetic pulses in response to a transmit timing signal, and a receiver (58) samples the sequence of electromagnetic pulses with controlled timing response to the samples. A timing circuit supplies the transmit timing signal to the transmitter and supplies the receive timing signal to the receiver. The receive timing signal causes the receiver to sample the sequence of electromagnetic pulses such that the time between transmission of pulses in the sequence and sampling by the receiver sweeps over a range of delays.
