Abstract:
A composition comprising a guest/host assembly having a spheroidal host assembly comprised of a hexamer of a methylene-bridged trihydroxybenzene tetramer and a guest component encapsulated within the spheroidal host assembly to provide a highly stable guest/host assembly. A guest component, specifically a pharmaceutically active agent, is encapsulated within the spheroidal host assembly to provide a guest/host assembly exhibiting a high stability, being stable upon a solubilization in a mixture of acetone and water in a one-to-one ratio for a period of one day at a temperature of 37 DEG C. The pharmaceutically active agent encapsulated within the spheroidal hexamer is selected from the group consisting of Depakote, Wellbutrin, Allegra, Neurontin, Zovirax, and Claritin. A process for the preparation of a hexameric complex, as described above, from a methylene-bridged tetramer solubilized in an amphiphilic organic solvent. An activator is incorporated into the amphiphilic solvent containing the tetramer. The activator comprises an organic compound of a lower molecular weight than that of the tetramer which is functionalized with at least one of an acidic group, a halogen, an amino group, an amido group, an ester group, or an hydroxy group. The tetramer may be prepared from an aldehyde and pyrogallol which are reacted under conditions to produce a condensation product of the methylene-bridged cyclic tetramer.

Abstract:
A method of producing a ceramic weld, including identifying a ceramic first surface an a ceramic second surface to he bonded together, maintaining a non-oxidizing atmosphere over the first and second surfaces, and engaging the first and second surfaces to define a joint, An arc is generated between an electrode and the joint to create a liquid phase, and the liquid phase is cooled to yield a solid fusion layer, wherein the first and second surfaces are joined in the fusion layer.

Abstract:
The present invention identifies the cholesterol biosynthetic pathway, including the enzyme oxidosqualene cyclase, as new protein targets for anti-tumor therapeutics. The present invention further provides a class of oxidosqualene cyclase inhibitors containing a tertiary amine linked with aromatic ring structures, as a new class of anticancer agents. Compounds disclosed herein have been tested in 19 cell lines including breast cancer, prostate cancer, lung cancer (including drug-resistant lung cancer H69AR), colon cancer, ovarian cancer (including drug-resistant OVCAR-3), and pancreatic cancer cells, as wells as in human breast and prostate xenograft tumor growth in nude mice, and have been shown to be active.
