Abstract: Carbon with mesopores (about two to fifteen nanometers in average pore size) is made using sucrose as a source of carbon, and silica and phosphoric acid as templates for the mesopore structure in the carbon. A silica sol is prepared in a water/ethanol medium and sucrose is dispersed in the sol. Phosphoric acid may be added to the sol to control pore size in the mesopore size range. The sol is dried, carbonized, and the silica and phosphate materials removed by leaching. The residue is a mesoporous carbon mass having utility as a catalyst support, gas absorbent, and the like.

Abstract: Provided is a novel method for detecting Transmissible Spongiform encephalopathies (TSE). The method comprises: selecting a body fluid sample from a subject to determine whether the subject has transmissible spongiform encephalopathy; and detecting antibodies that immune react with Spiroplasma proteins in the sample. The method detects antibodies in the individual sera samples that react with recombinant Spiroplasma-specific Hsp60 by standard ELISA methodology. This method provides for rapid detection of TSE by determination of presence of antibodies in test samples showing associated Spiroplasma infection that has become consistent with presence of TSE. The method provides a mechanism to detect presence of TSE without invasive techniques currently needed to make diagnosis using brain tissues for prion detection. This method provides means of detection of TSE in the live patient without need for using necropsy tissues.

Abstract: A novel top-down procedure for synthesis of stable passivated nanoparticles uses a one-step mechanochemical process to form and passivate the nanoparticles. High-energy ball milling (HEBM) can advantageously be used to mechanically reduce the size of material to nanoparticles. When the reduction of size occurs in a reactive medium, the passivation of the nanoparticles occurs as the nanoparticles are formed. This results in stable passivated silicon nanoparticles. This procedure can be used, for example in the synthesis of stable alkyl- or alkenyl-passivated silicon and germanium nanoparticles. The covalent bonds between the silicon or germanium and the carbon in the reactive medium create very stable nanoparticles.

Abstract: The present invention relates to peptides and methods of inhibiting fusion between the virion envelope of Flaviviruses and membranes of the target cell, the process that delivers the viral genome into the cell cytoplasm. The invention provides for methods which employ peptides or peptide derivatives to inhibit Flavivirus:cell fusion. The present invention is based in part on the discovery that E1 envelope glycoprotein of hepaciviruses and E2 envelope glycoprotein of pestivirus have previously undescribed structures, truncated class II fusion proteins. The present invention provides peptides and methods of treatment and prophylaxis of diseases induced by Flaviviruses.

Abstract: The present invention provides novel peptides which specifically targets and binds to dendritic cells.

Methods of using the peptides or fusion compositions to promote an immune responses in an individual via administration also are provided.

Abstract: A process for synthesizing a metal telluride is provided that includes the dissolution of a metal precursor in a solvent containing a ligand to form a metal-ligand complex soluble in the solvent. The metal-ligand complex is then reacted with a telluride-containing reagent to form metal telluride domains having a mean linear dimension of from 2 to 40 nanometers. NaHTe represents a well-suited telluride reagent. A composition is provided that includes a plurality of metal telluride crystalline domains (PbTe)1-x-y(SnTe)x(Bi2Te3)y??(I) having a mean linear dimension of from 2 to 40 nanometers inclusive where x is between 0 and 1 inclusive and y is between 0 and 1 inclusive with the proviso that x+y is less than or equal to 1. Each of the metal telluride crystalline domains has a surface passivated with a saccharide moiety or a polydentate carboxylate.

Abstract: A method of treating preeclampsia including administering a therapeutically effective dose of resibufagenin to a patient having preeclampsia. Effecting the determination of the presence of preeclampsia may be by determining whether there has been a substantial elevation in marinobufagenin which may be blood-derived or urine-derived and if such elevation does exist, concluding that preeclampsia does exist. The method may advantageously be practiced by employing urine, blood serum or blood plasma as the body specimen containing the protein in determining whether a patient has preeclampsia. In another embodiment, bufodienolide derivatives other than resibufagenin may be employed in lieu of thereof or in combination therewith. In another embodiment, resibufagenin analogues may be employed in the treatment of preeclampsia.

Abstract: Titanium oxide (usually titanium dioxide) catalyst support particles are doped for electronic conductivity and formed with surface area-enhancing pores for use, for example, in electro-catalyzed electrodes on proton exchange membrane electrodes in hydrogen/oxygen fuel cells. Suitable compounds of titanium and a dopant are dispersed with pore-forming particles in a liquid medium. The compounds are deposited as a precipitate or sol on the pore-forming particles and heated to transform the deposit into crystals of dopant-containing titanium dioxide.
