    Abstract: The invention provides a method for generating and selecting drug-sensitizing antisense DNA fragments. In one embodiment, the method includes identifying a gene of interest using knowledge of bacterial physiology, biochemistry, genetics, genomics, and other means. The method includes PCR amplification of a gene of interest using genomic DNA as a template; fragmentation of the DNA by sonication or other means; selecting DNA fragments no longer than 400 base pairs; ligating the DNA fragments into a suitable expression plasmid with a selectable marker; transforming the plasmids containing the DNA fragments into the organism from which the gene of interest originated; and selecting clones from transformed cells that show a phenotypic difference of the clone grown in the presence of the inducer relative to the phenotype in the absence of inducer.

    Abstract: An exterior rear view mirror assembly is disclosed which incorporates a warning light actuatable in conjunction with the vehicle turn signals to alert adjacent motor vehicles of an anticipated turn. The warning light is integrated into a first decorative cover member and may be connected to the vehicle turn signal circuit by way of connectable electrical leads or by an integrally formed plug and outlet arrangement. A second decorative cover member may be substituted for the first decorative cover member when it is not desired to incorporate the warning light.

    Abstract: The present invention provides a pharmaceutical composition useful for treating bacterial infections in humans and animals which comprises administering to a human or animal in need thereof, an antibacterially effective combination of a β-lactam antibiotic and an inhibitor of any bacterial peptidoglycan biosynthesis enzyme, especially GlmU, GlmU, MurA, MurB, MurC, MurD, MurE, MurF, MurG, MraY, and UppS. Further provided is a method of discovering synergists for antibiotics including: a) expressing in a cell an antisense nucleic acid against a nucleic acid encoding a gene product so as to reduce the activity or amount of the gene product in the cell, thereby producing a cell sensitized to an antibiotic; b) characterizing the sensitization of the cell to the antibiotic and selecting pairs of antibiotics and genes that result in antibiotic efficacy at one-fifth or less the concentration required in the absence of the antisense gene; c) screening for chemical compounds that inhibit the gene product corresponding to the selected synergistic gene; and d) selecting or creating chemical analogs that inhibit the gene product corresponding to the selected synergistic gene such that the inhibition occurs in the bacteria.
