  • Publication number: 20130259842
    Abstract: The present invention relates to a stable pluripotent reprogrammed cells, and compositions and methods of isolation and uses thereof, wherein the stable pluripotent reprogrammed cells is derived from a somatic cell and has undergone incomplete remodeling of the epigenome. In some embodiments, the stable reprogrammed cell is a human stable reprogrammed cell. In some embodiments, the stable reprogrammed cell has a statistically significant lower level of expression of one or any combination of Nanog, Dnmt3b, Lefty2 as compared to an induced pluripotent stem cell. In some embodiments, the stable reprogrammed cell has a statistically significant higher level of expression of one or any combination of Tdgf1, Tert or endogenous Sox2 as compared to a somatic cell from which it was derived. In some embodiments, the stable reprogrammed cell has a statistically significant faster rate of doubling as compared to an induced pluripotent stem cell (iPSC) or an embryonic stem (ES) cell.

  • Patent number: 8219541
    Abstract: A system and method for automatically detecting, reporting, and tracking conflicts in a change management system is provided. In particular, the system and method described herein may be used to identify potential conflicts associated with resources and schedules involved in a proposed change to an information technology infrastructure. A conflict analysis engine may analyze a change order that includes planned changes to an information technology infrastructure to identify potential conflicts associated with the change order that includes the planned changes to the information technology infrastructure. The potential conflicts may then be added to a conflicts list for the change order and a workflow may be created to manage resolving the potential conflicts. Thus, in response to resolving the potential conflicts, the planned changes may be deployed within the information technology infrastructure.

  • Publication number: 20120021519
    Abstract: The disclosure features a method of producing a reprogrammed cell (e.g. an induced pluripotent stem cell or an undifferentiated cell) from a differentiated (e.g. somatic) cell. In some embodiments, the methods includes contacting a differentiated (e.g. somatic cell) with a TGFBR1 inhibitor or anti-TGF-?-antibody to produce a reprogrammed cell (e.g. pluripotent stem cell or undifferentiated cell). Embodiments of the present invention relate to a reprogrammed cell and methods and compositions for producing a chemically produced reprogrammed cell or populations thereof.

  • Patent number: 7418695
    Abstract: Methods, systems, apparatus and computer-readable media are disclosed for providing cross-platform software dependency information. A first exemplary method is disclosed that includes receiving a request for software dependency information relating to a number of platforms. The method also includes identifying a set of applications, each application corresponding to a one of the set of platforms. The method further includes transmitting to each of the identified applications a platform-specific software dependency query. A response to each platform-specific software dependency query is received from each of the identified applications, and the are combined into a combined query result. The method still further includes transmitting the combined query result containing the software dependency information in response to the initial query. Other methods, apparatus, systems and computer readable media are disclosed for presenting cross-platform software dependency information.
