  • Patent number: 10576730
    Abstract: The imaging sensitivity of negative-working lithographic printing plate precursors is improved by removing ozone from the ambient air surrounding the precursors that can be stored near an imaging means such as a platesetter prior to use. Ozone can be removed using a suitable filter containing activated charcoal or other ozone decomposing means, through which ambient air is filtered before and during the imaging process.

  • Patent number: 9234897
    Abstract: Disclosed is a method for distinguishing a mesenchymal stem cell comprising, using at least one gene selected from the genes having the nucleotide sequences indicated by the accession numbers shown in Table 1 as a distinguish marker, detecting the difference in expression of the distinguish marker between a mesenchymal stem cell and a connective tissue cell to distinguish the mesenchymal stem cell from the connective tissue cell. This method enables to distinguish an undifferentiated mesenchymal stem cell from other connective tissue cell such as fibroblasts, osteoblasts, chondrocytes and adipose cells with good accuracy. A mesenchymal stem cell given by this method or a composition comprising the mesenchymal stem sell can be used as a therapeutic for use in the regenerative medicine.

  • Patent number: 8383319
    Abstract: Lithographic printing plate precursors have been designed so that they can be stored, shipped, and used in stacks without interleaf paper between individual precursors. This is achieved by incorporating polymeric particles having an average diameter of from about 3 to about 20 ?m into the outermost precursor layer such as an imagable layer or topcoat. The polymeric particles comprise a core of a crosslinked polymer and have grafted hydrophilic polymeric surface groups that are grafted onto the particle surfaces by polymerizing hydrophilic monomers in the presence of the crosslinked polymeric particles. The lithographic printing plates can be either negative- or positive-working elements.
