    摘要： A strategy for suppressing specifically or partially specifically an endogenous gene and introducing a replacement gene, said strategy comprising the steps of: 1. providing suppressing nucleic acids or other suppression effectors able to bind to an endogenous gene, gene transcript or gene product to be suppressed and 2. providing genomic DNA or cDNA (complete or partial) encoding a replacement gene wherein the suppressing nucleic acids are unable to bind to equivalent regions in the genomic DNA or cDNA to prevent expression of the replacement gene. The replacement nucleic acids have modifications in one or more third base (wobble) positions such that replacement nucleic acids still code for the wild type or equivalent amino acids.

    摘要： A digital alarm system of the type having first and second electrically conductive loops connected by an alarm switch. The alarm switch is normally open, but can be closed when an alarm state exists to electrically short one loop to the other. Currents are generated in each of the loops for use in detecting either the closing of the alarm switch or the occurrence of a fault in one of the loops. Resistors are connected to each of the loops for use in detecting the presence or absence of the currents. A first pair of transistor switches alternatingly short-circuit one resistor then the other; and a second pair of transistor switches, synchronized with the first pair, alternatingly short the ends of one loop then those of the other so that when the alarm switch is closed the first pair of transistor switches simultaneously short-circuit both resistors even if a fault occurs anywhere in one of the loops. Recording devices, such as flip-flops, coupled to the resistors, record signals indicative of a magnitude of the resistor voltage drops during intervals in which the resistors are not short-circuited. Logic circuitry is then used to process this stored information to generate signals indicating whether the alarm switch has been tripped or whether a fault has occurred.

    摘要： The present invention is directed to a method and use of RNA interference (RNAi) for the transient, reversible and controlled opening of the tight junctions of the blood brain barrier and/or the blood retinal barrier. This method may be used in the treatment of many diseases and disorders which require the opening of the blood brain barrier and/or blood retinal barrier. Such methods generally involve the use of an RNAi-inducing agent, such as siRNA, miRNA, shRNA or an RNAi-inducing vector whose presence within a cell results in production of an siRNA or shRNA, targeting tight junction proteins to open the blood brain barrier and/or blood retinal barrier.
