  • Patent number: 8211646
    Abstract: Genomic analysis of ovarian cancers demonstrated a regional chromosomal increase in expression and gene duplication. TGF-? stimulation indicated a link between SnoN RNA and TGF-?. In TIOSE, SnoN protein levels were reduced 15 min post TGF-?-stimulation, likely by proteosome-mediated degradation. SnoN inhibition decreased cell growth between 20 and 50% concurrent with increased p21 levels. Stable expression of SnoN led to growth arrest through induction of senescence. Collectively, these results implicate SnoN levels in multiple roles during ovarian carcinogenesis: promoting cellular proliferation in ovarian cancer cells and as a positive mediator of cell cycle arrest and senescence in non-transformed ovarian epithelial cells.

  • Publication number: 20120045837
    Abstract: Indicator inks, indicators formed by printing or otherwise utilizing the inks and host products utilizing the indicators are disclosed. Reactivity-enhancing adjuvants stimulate enhanced thermal reactivity of diacetylenic or other indicator agents capable of responding to ambient thermal conditions with a visual change signaling an end point. The diacetylenic or other agents may be sensitive or relatively insensitive to ambient temperatures. Use of a reactivity-enhancing adjuvant provides a useful means for adapting the reactivities of indicator agents to the response characteristics of prospective host products, for example perishables such as vaccines or fresh fish and maturables such as fruit, cheese and wine. Some exemplary adjuvants include low-temperature polymerization initiators, for example methyl ethyl ketone peroxide and polymerization accelerators, for example cobalt compounds. Such initiators and accelerators can also be used in combination.

  • Publication number: 20090230575
    Abstract: The invention provide a method for cast-molding hydrogel contact lenses, especially silicone hydrogel contact lenses by using plastic molds of a poly(cycloalkylene-dialkylene terephthalate) copolymer. These plastic molds do not need to be degassed and stored in an oxygen-free atmosphere (e.g., N2 or Ar) before being used for cast-molding silicone hydrogel contact lenses in the absence of oxygen and resultant silicone hydrogel lenses can still have relatively high ion permeability and relatively low variation in targeted optical power, compared with silicone hydrogel lenses made from a conventional mold material, such as polypropylene. The invention also provides plastic molds for cast-molding silicone hydrogel contact lenses.

  • Publication number: 20080257251
    Abstract: A freeze indicator employs, as active indicator element, dispersion of solid particles in a liquid medium which can be water or aqueous and which coagulates to provide an irreversible appearance change when subject to freezing. The liquid dispersion can be contained in an indicator volume around which extends a vapor block layer. The vapor block layer can prevent loss of liquid vapor from the dispersion and consequent drying out and dysfunctionality of the freeze indicator. For containing an aqueous medium, bilayer and trilayer laminate materials can be used which have a low water vapor transmission rate. The active indicator element can be a dilute colloidal dispersion of a metal such as gold or silver or other inorganic pigment material in water or an aqueous medium. Some embodiments avoid use of dispersants and the like and employ an active indicator element consisting of inorganic pigment particles, water and optionally an ice nucleating agent.
