  • Publication number: 20220017609
    Abstract: Antibodies that penetrate cell nuclei and inhibit DNA repair or interfere with DNA metabolism are provided for treatment of cancer (both directly and by sensitizing cancer cells to DNA-damaging treatments) or inhibiting or preventing viral infection, proliferation or metabolism. The method involves treating cells with a composition containing cell-penetrating anti-DNA antibodies or derivatives thereof, alone or in combination with treatment that induces DNA damage such as DNA-damaging chemotherapy or radiation. The impact of the cell-penetrating anti-DNA antibodies or derivatives thereof is potentiated in cancer cells that are deficient in DNA repair, and the cell-penetrating anti-DNA antibodies or derivatives thereof are synthetically lethal to cancer cells with DNA repair deficiencies.

  • Patent number: 7060172
    Abstract: The apparatus includes a container (20) having a base (22) and sides (32) adapted to receive a plurality of plastic gel cassettes. An inlet port (12) is positioned in the base of the container and in fluid communication with the chamber and a baffle (11) is positioned over the inlet port, such that, in use, when gel forming fluid passes through the inlet port into the chamber, the baffle substantially reduces fluid turbulence and vertical fluid movement in the vicinity of the inlet port during flow of the fluid into the chamber. Pretreatment of the plastic cassette to remove polymerisation inhibitors prior to filling the same with fluid is by exhaustive vacuum treatment, optionally with nitrogen gas purging. This can be achieved conveniently using a vacuum chamber in which one or more plastic cassettes are placed. Optionally the vacuum chamber may be the container in which the cassettes are filled with fluid. No barrier films or chemical scavengers are required.

  • Publication number: 20050228120
    Abstract: A polymer comprising one or more macromonomer units selected from the group consisting of polysiloxane, perfluoroalkylpolyether (PFPE), fluorinated poly(meth)acrylate, polyalkyl (meth)acrylate, polyolefin and fluorinated polyolefin, and one or more charged units (such as an anionic, cationic or zwitter-ionic monomer), formed from a polymerization medium containing an aqueous solution of charged units and use of this polymer as an intraocular lens for the implantation into or onto the cornea. Another aspects relates to a process for coating the above polymer with an adhesive comprising covalently coupling co-reactive surface functional groups of a natural or synthetic polymer with functional groups present (or introduced) on the surface of the macromonomer containing polymer, followed by covalently coupling a multifunctionally activated compound having at least one functional group that is co-reactive to the reactive groups of the natural or synthetic polymer.
