Abstract: The present invention relates to novel antimycobacterial compounds and in particular to antimycobacterial compounds comprised of Schiff base, diacylhydrazine, sulfur-containing diacylhydrazine and oxadiazoline congeners of isonicotinic acid hydrazide. This invention further relates to processes for their preparation, to intermediates useful in their preparation, to their use as therapeutic agents and to pharmaceutical compositions containing them.

Abstract: The present invention relates to novel antimycobacterial compounds and in particular to antimycobacterial compounds comprised of derivatives of phenyl 4-aminosalicylate. This invention further relates to methods for their preparation, to their use as therapeutic agents and to pharmaceutical compositions containing them. The novel methods of the invention yield derivatives of phenyl 4-aminosalicylate on a multi-gram scale and in high purity for subsequent biological evaluation in drug discovery.

Abstract: A system is disclosed for error diffusion dithering. The system includes an input for receiving an input matrix representative of image data, and a plurality of processors. The plurality of processors processes the input matrix and provides output data. Each of the processors is in communication with at least a portion of the input matrix. At least one processor processes a portion of the input matrix defined at least in part by a substantially diagonal edge within the image matrix.

Abstract: The subject invention concerns a nucleic acid comprising a nucleotide sequence encoding human interleukin-1 (IL-1), and fragments thereof, and the polypeptides and peptides obtained. Specifically, the subject invention comprises the cloning of a cDNA synthesized by reverse transcription of poly(A)RNA isolated from adherent human monocytes stimulated with bacterial endotoxin. Human IL-1 is useful to induce the production of IL-2 by activated T-cells; it also acts on B-cells and NK-cells. The subject invention further concerns antibodies that are immunoreactive with human IL-1.beta. proteins.

Abstract: Disclosed is a transgenic non-human mammal that expresses in its brain a transgene encoding an APP-C100 polypeptide with the flag amino acid sequence fused to the amino terminus of the APP-C100. This transgenic non-human mammal is an improved in vivo model for Alzheimer's disease-like neuropathology and associated cognitive impairment. The improvement includes accelerated development of AD-like neuropathology and cognitive impairment. The AD-like neurodegeneration and associated cognitive impairment in mice produced according to this invention appear at least six months sooner than they appear in APP-C100-expressing transgenic mice.

Abstract: The subject invention concerns truncated human Il-1 cDNA sequences which encode biologically-active novel human IL-1 proteins. These truncated human IL-1 cDNA sequences can be obtained by genetic engineering procedures using a clone of human IL-1 cDNA, having the accession number NRRL B-15770, as a starting material. The truncated human IL-1 cDNA sequences of the subject invention are contained in specified plasmids whose constructions are described in detail. Biologically-active human IL-1 proteins are useful to induce the production of IL-2 by activated T-cells. They also act on B-cells and NK-cells.

Abstract: The invention is directed to an Arg-Serpin human plasminogen activator inhibitor designated PAI-2. This protein is prepared via recombinant DNA means. The invention also includes other serpins which can be made by amino acid substitutions or deletions in conserved regions of PAI-1 and PAI-2, as shown in FIG. 4. The proteins of the invention can be used to inhibit, or at least modulate, human plasminogen activator activity in a variety of physiological conditions, e.g., fibrinolysis, tumor metastasis, and tumor growth.
