  • Patent number: 6512876
    Abstract: A fiber splice tray for optical fiber splices capable of holding multiple single fiber splices, ribbon fiber splices and combinations thereof having a base, a plurality of adjacent opposed retention members extending upwardly from the base and a plurality of adjacent opposed extension members extending upwardly from the base in an area between opposed retention members. The opposed extension members are separated by a space for accepting at least a portion of a fiber ribbon splice and the retention members terminate in opposed arms for accepting a single fiber splice. The fiber splice tray can include an opening through the base bounded by a shelf for the fiber or ribbon extending from the splice to pass, to assist in preventing the splice from coming dislodged from the retention member.

  • Patent number: 6180681
    Abstract: The invention relates to 2-cyclopenten-1-one as an inducer of the heat shock protein HSP70 by activating the heat shock transcription factor HSF, and selectively inducing the transcription and translation of HSP70 in human cells. In particular, since a cytoprotective role of HSP70 during viral infection was previously shown, the invention refers to 2-cyclopenten-1-one and its pharmaceutically acceptable derivatives as inducers of HSP70 with antiviral activity. Treatment with 2-cyclopenten-1-one and its pharmaceutically acceptable derivatives causes a dose-dependent reduction of infectious virus yield during infection with vesicular stomatitis virus. The block of virus replication is due to inhibition of viral protein synthesis, associated with HSP70 synthesis.

  • Patent number: 6177409
    Abstract: Process for regiospecific preparation of new 3-hydroxypyridine-4(1H)-one derivatives starting from monosaccharides or itols of general formula: in which R represents a radical, either saturated or not, branched or not, having carbon-atom groups, and having hetero-atoms or not, and Sub represents a saccharide derivative or an itol, either cyclic not, protected or not, the hydrocarbon skeleton of which is bound to the nitrogen atom of the pyridinone either directly or by the intermediary of a spacing group. The present invention is characterized in that the process comprises a first step of protection of the 3-hydroxy group of the pyranone derivative, a second basocatalyzed step of substitution of the intracyclic oxygen atom of the pyranone by the nitrogen atom of the amine function of the amino monosaccharide or amino itol, and a third step of de-protection of the 3-OH group of the pyridinone cycle and possibly of the OH groups of the glucide or itol residue.
