  • Publication number: 20050171138
    Abstract: Compounds are described having a structure according to Formula I or Formula II: wherein: X is selected from the group consisting of O, NH, and S; Y is selected from the group consisting of O and S; m is from 1 to 3; n is from 1 to 5; R1 and R3 are each independently selected from the group consisting of H, hydroxy, lower alkyl, lower alkoxy, halo, amino, aminoalkyl, nitro, heteroaryl, —OC(?O)R6, —O(C?O)OR6; and —O(C?O)N(R6)2; and R2 is side chain such as an acetic acid side chain, where p is O to 4, R5 is hydroxy, alkoxy or amino, and R6 is H or lower alkyl, or a pharmaceutically acceptable salt thereof. The compounds are useful for the treatment of cancer.

  • Publication number: 20050168130
    Abstract: An electrode structure for a display device comprising a gate electrode proximate to an emitter and a focusing electrode separated from the gate electrode by an insulating layer containing a ridge are provided. When the focusing electrode is an aperture-type electrode, the ridge protrudes closer to the emitter than the sidewall of the gate electrode or the sidewall of the focusing electrode. When the focusing electrode is a concentric-type electrode, the ridge protrudes above the upper surface of the gate electrode or the upper surface of the focusing electrode. A method for making the aperture-type and concentric-type electrode structures is described. A display device containing such electrode structures is also described. By forming an insulating ridge between the gate and focusing electrodes, shorting between the two electrodes is reduced and yield enhancement increased.

  • Publication number: 20040176426
    Abstract: The present invention provides compounds, pharmaceutical compositions and methods that are useful in modulating the farnesoid X receptor (FXR). As FXR is involved in negatively controlling the expression level of cholesterol 7&agr;-hydroxylase (cyp7a), the rate-limiting enzyme involved in the oxidative metabolism of cholesterol into bile acids, the compounds described herein find utility in treating diseases associated with abnormally high or low cholesterol levels. In certain aspects, the FXR modulators (e.g., antagonists) described herein block the negative feed-back downregulation of cyp7a expression produced by certain cholic acids, the endogenous ligands for FXR. Moreover, as FXR forms heterodimers with the retinoid X receptor (RXR) in some cell types, modulation of the level of FXR activity in cells has a wide range of effects on a variety of biological processes which are mediated by RXR or other RXR-interacting proteins such as PPAR&ggr; and PPAR&agr;.

  • Patent number: 6734619
    Abstract: A flat-panel display and process for forming the flat-panel display having an array of spacer columns anodically bonded to one of the inner major faces on one of the generally planar plates of the evacuated, flat-panel video display. The process includes providing a generally planar plate having a plurality of spacer column attachment sites; providing electrical interconnection between all attachment sites; coating each attachment site with a patch of oxidizable material; providing an array of unattached permanent glass spacer columns, each unattached permanent spacer column being of uniform length and being positioned longitudinally perpendicular to a single plane, with the plane intersecting the midpoint of each unattached spacer column; positioning the array such that an end of one permanent spacer column is in contact with the oxidizable material patch at each attachment site; and anodically bonding the contacting end of each permanent spacer column to the oxidizable material layer.
