Abstract: A psoriasis susceptibility locus defined as among linked members within a family has been identified. The locus is linked to an intron of the interleukin enhancer binding factor gene in some families, while being linked to an interleukin 8 gene in other families demonstrating a familial linked form of psoriasis. The locus identified may be further defined as being located distal to genetic maker D17S784 of human chromosome 17q. This locus does not demonstrate linkage with DNA markers within flanking the HLA cluster of genes. A psoriasis susceptibility locus has also been observed close to the centromere of human chromosome 4. Both identified regions provide positive LOD scores with markers on chromosomes 17q and particularly 2 regions close to the ILF gene or the interleukin 8 gene. Methods of screening a family for psoriasis susceptibility using a defined familial psoriasis susceptibility locus are also disclosed.

Abstract: The present invention relates to a newly identified family of protein serine/threonine kinases which phosphorylate microtubule-associated protein 2 (MAP2). It is based, in part, on the cloning and characterization of novel MAP2 kinases designated extracellular signal-regulated kinase 1, 2, and 3 (ERK1, ERK2, ERK3) which are expressed in the central nervous system, and on the identification of another ERK family member, ERK4, with antisera. The present invention provides for recombinant nucleic acid molecules and proteins representing members of the MAP2 kinase family, and also for microorganisms, transgenic animals, and cell lines comprising recombinant MAP2 kinase molecules. In additional embodiments of the invention, the present invention provides for methods for assaying cellular factor activity, including, but not limited to, nerve growth factor activity, in which the activation of MAP2 kinase serves as an indicator of cellular factor activity.

Abstract: A mold useful for injection molding, comprising: a porous network of metal and oxidized metal and a cured epoxy resin dispersed in the porous network. The mold can be prepared by a process comprising the sequential steps of (a) forming a mixture of a metal powder and a polymer binder; (b) heating the mixture at a temperature in the range from about 100.degree. C. to about 300.degree. C. to remove a majority of the polymer binder from the mixture; (c) heating the mixture resulting from step (b) at a temperature greater than about 300.degree. C. and less than the melting point of the metal in the presence of oxygen to oxidize at least a portion of the metal to form a self-adhering porous network of metal and oxidized metal; (d) contacting the self-adhering porous network with an epoxy resin to fill at least a portion of the porous network with epoxy resin; and (e) curing the body resulting from step (d) to form the mold. The shape of the mold can be performed by selective laser sintering of the mixture.

Abstract: The synthesis and characterization of novel molecular sieves containing bis(pentamethylcyclopentadienyl) cobalt(III) ion are described. Several types of molecular sieves were prepared using the cobalt metal complex as a template that was shown to be incorporated as a guest molecule within the molecular sieve. Molecular sieves prepared using bis(pentamethylcyclopentadienyl) cobalt(III) ion as template were characterized as having a pore size at least as large as 7 .ANG.. Other molecular sieves were also prepared using bis(cyclopentadienyl) cobalt(III) templates. The compounds are attractive as catalysts in a wide range of applications.

Abstract: The invention is directed to improving the disinfection of dental impressions following removal from the patient's mouth and before entering the dental laboratory to prevent contamination. It involves the use of a pH-adjusted hypochlorite solution, which is highly effective in killing microorganisms, and also relatively inexpensive. Using the solution of the instant invention for disinfection causes no damage to the impression, no loss of accuracy, and does not destroy the details on the impression surface.

Abstract: An MPEG-2 decoder circuit achieves smaller circuit area, and hence lower cost, by using circuitry, including ROMs, designed to implement residue arithmetic to calculate discrete cosine transforms in a pipelined or iterative fashion. A variable-length decoder based on ROM-like PLAs parses the stream of data to separate audio from video data and to direct the necessary operations on the data elements. The decoder and data flow through the system are controlled by a conditional MOVE processor, which is implemented as a data memory.

Abstract: Texaphyrins are provided for use as radiation sensitizers. Advantageous properties of texaphyrins for use as a radiation sensitizer include: i) a low redox potential which allows radiation-induced hydrated electrons to flow to texaphyrin rather than neutralizing hydroxyl radicals, allowing hydroxyl radicals to cause cellular damage, ii) a relatively stable texaphyrin radical that reacts readily to covalently modify neighboring molecules causing further cellular damage, iii) intrinsic biolocalization, and iv) indifference to the presence or absence of O.sub.2. These properties allow texaphyrins to be particularly effective for treating the hypoxic areas of solid neoplasms. Methods of treatment for an individual having a neoplasm or atheroma include the use of a texaphyrin as a radiation sensitizer and as an agent for photodynamic tumor therapy, or the use of a texaphyrin for internal and for external ionizing radiation. Novel texaphyrins are provided.

Abstract: The invention is directed to a method of incorporating expanded porphyrins, and particularly of incorporating a sapphyrin or a texaphyrin, before, during, or after chemical synthesis of an oligomer to form an expanded porphyrin-oligonucleotide conjugate, and particularly a sapphyrin- or texaphyrin-oligonucleotide conjugate. This method includes reacting derivatized nucleotides and a sapphyrin or a texaphyrin in a desired order in an automated or manual DNA synthesizer having a solid support to form a sapphyrin- or a texaphyrin-oligonucleotide conjugate.

Abstract: A biodegradable implant for placement in nonunion bone fractures as a substitute for bone graft material is provided which is a flat plate or disk having a thickness of between about 1 mm and about 15% of the length of the bone, interconnected micropores, and canals substantially equivalent in size and spacing to naturally-occurring Haversian canals. The implant may additionally comprise additives such as growth factors, including bone morphogenic protein. In a preferred embodiment the implant is formed from a biodegradable polymer such as a polylactic acid-polyglycolic acid copolymer by a gel casting technique followed by solvent extraction to precipitate the implant as a microporous solid.
