Abstract:
Methods are disclosed which are useful in increasing maturation of dendritic cells from CD14+ mononuclear cells, by contact with a composition comprising a fucose-containing glycoprotein fraction from Ganoderma lucidum. The extract can also be used for increasing production of a cytokine or a chemokine in a dendritic cell or CD19+ B cell. In addition, a fucose-containing glycoprotein fraction from Ganoderma lucidum can be administered to a subject identified as needing increased immunoglobulin, cytokine, or chemokine production.
Abstract:
A novel soluble pentacene (C22H14) precursor 6,13-dihydro-6,13-methanopentacene-15-one, a method for its production and intermediates therefor as well as pentacene films and coated surfaces. Thermolysis of the precursor at 150° C. to 350° C. induces an expulsion of carbon monoxide to generate pentacene in high yield. The high solubility of the precursor compound, as well as its production of non-contaminated pentacene, makes it an excellent material in the application of organic thin film transistors on surfaces.

Also disclosed are a vaccine containing the polypeptide, a method of producing the polypeptide, and a method of inducing an immune response in a subject by administering to the subject an effective amount of the polypeptide.
Abstract:
The present disclosure provides methods for increasing the lipopolysaccharide-induced secretion of IL-1 by macrophages, for increasing serum levels of IL-1 in a mammal, for increasing the serum level of IL-1 receptor antagonist (IL-1Ra) in a mammal, for increasing the secretion of IL-1 by a monocyte, for increasing the secretion of IL-1Ra by a monocyte, for increasing the secretion of IL-1Ra by a macrophage, for increasing expression of TLR4 on the surface of a macrophage, for increasing expression of CD14 on the surface of macrophage, for increasing the uptake and clearance of lipopolysaccharide (LPS) by a LPS-stimulated macrophage, and for increasing lipopolysaccharide (LPS)-stimulated activation of at least one of ERK, JNK, and p38 in a macrophage. The methods of the disclosure involve the administration to mammals and immune cells of a fucose-containing glycoprotein fraction from Ganoderma lucidum.
Abstract:
The disclosure provides fusion proteins comprising a carbohydrate recognition domain of an innate immunity receptor and a heterologous polypeptide. The fusion proteins of the disclosure may be used, for example, to fingerprint polysaccharide compositions and to purify polysaccharide compositions. Polysaccharide compositions include those isolated from Ganoderma lucidum (Reishi). The methods and reagents of the disclosure may also be used to identify innate immunity receptors and cell types that bind to polysaccharide compositions (including polysaccharide compositions associated with pathogens), whereupon modulators of the identified receptors can then be obtained. The fusion proteins also may be used to inhibit the interaction between a polysaccharide composition and an innate immunity receptor on a cell surface. The methods and reagents of the disclosure are used in one example to determine that the DLVR1 innate immunity receptor on macrophages interacts with Dengue virus (DV), and that DLVR1 is responsible for DV-mediated secretion of proinflammatory cytokines from macrophages. The disclosure also provides DVLR1 antibodies that prevent the secretion of proinflammatory cytokines by DV-infected macrophages.
Abstract:
The present invention discloses an asymmetric watermarking technology, which is particularly resistant to projection attack. The asymmetric watermark embedding technology of this invention comprises the following steps: Analyze an original image φo to obtain its watermarking space W. Divide said watermarking space W to obtain two orthogonal subspaces g and h. Select an embedding key G, which is a matrix and which columns form bases of subspace g. Calculate a matrix H, HTG=0. Columns of matrix H form bases of subspace h. Calculate detecting key D: D=GT+BHT; wherein B is a matrix. Obtain a watermark w and embed said watermark w into said original image φo to obtain a watermarked image φw, as follows: φw=φo+Gw wherein D φo=mo is not a 0 vector.
Abstract:
A highly magnetically aligned metallothionein (MT) containing manganese (Mn) and cadmium (Cd) has been synthesized. The metallotionein has a formula of Mnx Cd7−x MT with x being in the range of 1 to 6. Its size and biological functions are similar as those of the native metallothionein as tested by dynamic light scattering, UV, and CD spectroscopic experimental methods. Its maximum magnetic moment per formula unit, in saturation field, is estimated to be 19.46 μB, and persists from 277 to 330 K.

Abstract:
A nanoparticle ion detector includes an ion trap that receives charged particles ejected from a mass selection device. A laser beam illuminates the particles to induce fluorescence, which is detected by the photon detector. Particles are periodically dumped from the ion trap. A mass spectrum of the charged particles can be obtained by comparing signals from the photon detector with the particle ejection characteristics of the mass selection device.
