摘要:
The invention provides anti-thiol reagents which inhibit enzyme activity of cell-associated protein disulfide isomerase (PDI) by oxidizing or blocking PDI active site vicinal thiol groups which normally participate in disulfide bond rearrangement of PDI substrates. Inhibition of this PDI function is particularly useful in blocking PDI-mediated entry of HIV or other virions into a host cell. The invention further provides an assay for the identification of such PDI inhibitors based on the discovery that inhibitors of the invention also induce shedding of the leucocyte L-selectin adhesion molecule.

The present invention provides novel haloenol lactones that are effective as active site inhibitors of cholesterol esterase. By inhibiting cholesterol esterase the inhibitors of the present invention provide a new approach to the treatment of hypercholesterolemia through limiting the bioavailability of dietary cholesterol.

The invention provides HARDS virus rDNA for expression in molecular clones. The expressed products are useful in immunodiagnostics, prophylactics, and therapeutics for the HARDS virus and related hantaviruses. Of particular interest are a type-specific epitope of the HARDS virus G1 protein, and dominant epitopes of the HARDS virus N protein cross-reactive with antibodies to the HARDS virus and the related hantavirus PHV, both expressed by cDNA clones according to the invention.
摘要:
1. A tool comprising: a body (10) comprising a pair of flexible leaves (12, 14) joined at their forward ends by a bridge (16) having an elongate aperture (22) therein, said leaves also being joined face-to face at their rearward ends, and being normally bowed outward from one another; and an elongated collet (40) having a rearward end affixed to the rearward ends of said leaves, and a bifurcated forward end comprising a pair of resiliently flexible tines (44, 46), each tine having thereon a jaw (48) protruding through said aperture, each jaw including an inwardly facing working surface (50) and an outwardly facing oblique cam surface (52) in a position to engage a side of said aperture, so that relative longitudinal movement between the bridge and the jaws, produced by squeezing the leaves together, causes interaction between the sides of the aperture and the cam surfaces to drive the jaws together is improved by providing that: the tines of the collet lie in a common plane perpendicular to and bisecting both of said leaves, the length of the aperture being aligned with said plane; and the two opposed leaves and the bridge are within a blank of sheet material, the aperture being formed within the sheet.
摘要:
A method for the manufacture of finely divided particles of palladium, palladium oxide or mixtures thereof comprising the sequential steps:
A. Forming an unsaturated solution of thermally decomposable palladium-containing compound in a thermally volatilizable solvent; B. Forming an aerosol consisting essentially of finely divided droplets of the solution from step A. dispersed in an inert carrier gas; C. Heating the aerosol to an operating temperature above the decomposition temperature of the palladium-containing compound, but below the melting point of palladium metal by which finely divided particles of palladium, palladium oxide or mixtures thereof are formed and densified; and D. Separating the particles of palladium, palladium oxide or mixtures thereof from the carrier gas, reaction by-products and solvent volatilization products.
摘要:
There is disclosed a process for producing metal oxide nanoparticles. The process includes the steps of: a) providing at least two precursor metal salt materials, b) passing the at least two precursor metal salt materials through a plasma torch forming a vaporized material, and then c) condensing the vaporized material forming a metal oxide nanoparticle.
摘要:
The present invention provides a method for synthesizing heat shock protein-peptide complexes comprising the steps of: adding a shock protein to a denatured protein matrix to bind the heat shock protein to the denatured protein matrix; and adding a complexing solution comprising a peptide to elute a heat shock protein-peptide complex. The present invention also provides a heat shock protein-peptide complex synthesized by the method of the invention. In addition the present invention provides an apparatus for synthesizing heat shock protein-peptide complexes comprising a heat shock protein complex bound to a denatured protein matrix. The present invention also provides a method for treating an allergic disease in which a heat shock protein-antigen complex is administered to a mammal in an amount sufficient to reduce the susceptibility of the mammal to a Th2 response for the allergic disease. The method of the present invention can be used either to prevent an invididual from having an allergic reaction to an allergic disease or to reduce the effects of an allergic disease in an individual already suffering from the allergic disease.
