Patent number: 7211562Abstract: The administration of cytotoxic agents followed by the administration of heat shock protein 90 inhibitors, such as ansamycins, has a synergistic effect on the growth inhibition of cells. This synergy occurs at doses of each cytotoxic agent that normally only causes minimal growth inhibition of cells. Such combination therapy thus allows one to use lower doses of cytotoxic agents to avoid or reduce their respective toxicity to patients without compromising their growth inhibitory effects. Thus, these combinations can be used for the treatment of an animal, preferably a mammal, that has a cell proliferative disorder, whether the cells have wild-type Rb or are Rb deficient or Rb negative. One such method, directed to treating cell proliferative disorders includes the step of administering a therapeutic effective amount of a cytotoxic agent followed by administering a therapeutic effective amount of a heat shock protein 90 inhibitor.Type: GrantFiled: November 1, 2001Date of Patent: May 1, 2007Assignee: Sloan-Kettering Institute for Cancer ResearchInventors: Neal Rosen, Pamela Nathalie Munster

Patent number: 7211641Abstract: Liquid crystal polycarbonates are made by forming a reaction mixture containing (a) an activated diaryl carbonate; (b) at least two species of aromatic diols selected from among resorcinol, 4,4?-biphenol, hydroquinone, methylhydroquinone, 4,4?-dihydroxyphenylether, dihydroxynaphthalene, including in particular the 2,6, 1,5, and 2,7 isomers, 4,4?-dihydroxybenzophenone and 2,6-dihydroxyanthraquinone (anthraflavic acid); and (c) optionally bisphenol A in a maximum amount of 10 mole %; and processing the reaction mixture in a melt transesterification reaction to form a liquid crystal polycarbonate. While the product composition has the same overall characteristics as compositions made using diphenyl carbonate as the donor moiety for the carbonate linkage, they are analytically distinguishable because of limited incorporation of intermediate or end-cap residues derived from the activated diaryl carbonate.Type: GrantFiled: February 27, 2004Date of Patent: May 1, 2007Assignee: General Electric CompanyInventors: Sheldon Shafer, Julia Lee

Patent number: 7196067Abstract: Compositions and a method are provided for the treatment of prostate and other endocrine tumors in mammals, including humans, by administration of an antisense oligodeoxynucleotide (ODN) which is complementary to a portion of the gene encoding IGFBP-2. Using the Shionogi tumor model in vitro and in vivo, the administration of such an ODN was shown to reduce proliferation of tumor cells, and also to delay the progression to androgen independence. Thus, treatment of prostate and other hormone-regulated cancer in mammals, including humans, and delay of the progression of prostate tumors to androgen independence is accomplished by administering to the mammal a therapeutically effective amount of an antisense oligodeoxynucleotide which is complementary to a portion of the nucleic acid sequence encoding IGFBP-2 and which reduces the amount of IGFBP-2 in the treated cells.Type: GrantFiled: September 13, 2001Date of Patent: March 27, 2007Assignee: The University of British ColumbiaInventors: Martin Gleave, Paul S. Rennie, Kiyama Satoshi, Colleen Nelson

Patent number: 7168833Abstract: Lenses for lamps can improve the quality of the light emitted through lens by interacting with the light bulb. Photoluminescent dyes as well as non-photoluminescent dyes may be incorporated into a polycarbonate lens in order to shift the chromaticity of the light source. Further, design features such as grooves or protrusions may be incorporated into the lens to allow light produced by the photoluminescent material to escape the lens and be added to the emitted beam to further shift the chromaticity. The emitted beam is of a legal color and intensity as defined per the SAE J578 and SAE J1383 standards. The lighting performance may also be improved in such manner as reducing discomfort glare, increasing brightness or producing a beam that enhances road visibility at night to the human eye.Type: GrantFiled: October 3, 2003Date of Patent: January 30, 2007Assignee: General Electric CompanyInventors: Philippe Schottland, Bart Terburg, David S.

Patent number: 7144733Abstract: Cells are rendered sensitive to stimulation by introducing into a non-photoreceptor cell nucleic acid sequences encoding at least an opsin gene product, an arrestin gene product, and the alpha subunit of the heterotrimeric G protein of the Gq family. The introduced sequences are expressed by the cell to yield at least the opsin gene product, the arrestin gene product, and the alpha subunit of the heterotrimeric G protein of the Gq family. Retinal or a derivative thereof capable of bonding with the opsin gene product to form a rhodopsin is provided to the cell. The cell is then irradiated with light having a wavelength capable of converting the rhodopsin to metarhodopsin. The conversion of rhodopsin to metarhodopsin triggers a cascade of intracellular responses within the cell resulting in an increased intracellular concentration of IP3 and calcium ions.Type: GrantFiled: August 16, 2002Date of Patent: December 5, 2006Assignee: Sloan-Kettering Institute for Cancer ResearchInventors: Gero Miesenböck, Boris V.

Patent number: 7094423Abstract: Fully lipid-encapsulated therapeutic agent particles of a charged therapeutic agent are prepared by combining a lipid composition containing preformed lipid vesicles, a charged therapeutic agent, and a destabilizing agent to form a mixture of preformed vesicles and therapeutic agent in a destabilizing solvent. The destabilizing solvent is effective to destabilize the membrane of the preformed lipid vesicles without disrupting the vesicles. The resulting mixture is incubated for a period of time sufficient to allow the encapsulation of the therapeutic agent within the preformed lipid vesicles. The destabilizing agent is then removed to yield fully lipid-encapsulated therapeutic agent particles. The preformed lipid vesicles comprise a charged lipid which has a charge which is opposite to the charge of the charged therapeutic agent and a modified lipid having a steric barrier moiety for control of aggregation.Type: GrantFiled: July 14, 2000Date of Patent: August 22, 2006Assignee: INEX Pharmaceuticals Corp.Inventors: Norbert Maurer, Kim F Wong, Pieter R.
