    Abstract: Superantibodies having enhanced autophilic, catalytic, and/or membrane-penetrating properties are prepared by affinity-based conjugation of a photoactivatable organic molecule to a target immunoglobulin. The photoactivatable organic molecule bears a chromophoric aromatic hydrocarbon moiety, which has affinity for the immunoglobulin. Upon photolysis, the organic molecule is covalently linked to the immunoglobulin. A preferred organic molecule is a peptide and a preferred aromatic hydrocarbon moiety is a tryptophan residue. The photoactivatable organic molecule need not bear a purine, pyrimidine or azido group to effect binding to the immunoglobulin and/or photoactivation. Autophilic superantibodies can promote apoptosis of target cells and/or enhance therapeutic efficacies in the treatment of patients with diseases or disorders responsive to antibody therapy. Exemplary of such diseases are atherosclerosis and cardiovascular disease.

The collagen in the matrix may be cross-linked using photooxidative catalysis and visible light, and purified cell growth factors are preferably at least partly bone-derived.

  • Publication number: 20110251378
    Abstract: The present invention provides a one-pot method of preparing an unprotected ?-O-glycolipid. The first step involves contacting a protected ?-iodo sugar with a catalyst and a lipid comprising a hydroxy group, under conditions sufficient to prepare a protected ?-O-glycolipid. The second step involves deprotecting the protected ?-O-glycolipid under conditions sufficient to prepare the unprotected ?-O-glycolipid, wherein the contacting and deprotecting steps are performed in a single vessel. The present invention also provides a one-pot method of preparing an unprotected ?-O-glycolipid following the steps for the preparation of the unprotected ?-O-glycolipid.

  • Publication number: 20110224098
    Abstract: Apparatus, system, and method are provided for cutting a linear charged polymer inside a nanopore. A first voltage is applied to create an electric field in a first direction. A second voltage is applied to create an electric field in a second direction, and the first direction is opposite to the second direction. When the electric field in the first direction and the electric field in the second direction are applied to a linear charged polymer inside a nanopore, the linear charged polymer is cut at a location with predetermined accuracy.

  • Patent number: 7932065
    Abstract: Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful products, such as fuels. For example, systems are described that can use feedstock materials, such as cellulosic and/or lignocellulosic materials, to produce ethanol and/or butanol, e.g., by fermentation.

  • Publication number: 20110041473
    Abstract: An apparatus and method for in situ gas-phase formation and deflagration of nitrocellulose. A nitrating agent such as nitric acid and cellulose are delivered separately to a reaction chamber, where a brief heating pulse initiates nitration of the cellulose and deflagration of the nitrocellulose thus produced. Discharge of the high-pressure gases produced by the deflagration from the reaction chamber can then be used to drive an actuator, turbine, etc.

  • Publication number: 20100287826
    Abstract: A method of preparing cellulosic biomass material for subsequent processing first comprises moving at least one stream of biomass material along a flow path. Then, the stream of cellulosic biomass material can be explosively dried and pulverized to disrupt lignocellulosic bonds, and to reduce a moisture content and a particle size of the cellulosic biomass material. Then, the stream of cellulosic biomass material can be electrically degraded the stream of cellulosic biomass material to disrupt lignocellulosic bonds. Additional pre-treatment and post-treatment processes can also be included.
