Abstract: Disclosed is a method for removing minerals from a cellulosic biomass. For example, the biomass may be prewashed with an acid solution and rinsed with water to remove minerals prior to acid saccharification. The removal of minerals may reduce overall acid requirements, and decrease pretreatment costs.
Abstract: The present invention relates to novel regulatory T cell proteins. One protein, designated PD-L3, resembles members of the PD-L1 family, and co-stimulates ?CD3 proliferation of T cells in vitro. A second, TNF-like, protein has also been identified as being upregulated upon ?CD3/?GITR stimulation. This protein has been designated Treg-sTNF. Proteins, antibodies, activated T cells and methods for using the same are disclosed.

Abstract: The invention relates to a CD161 ligand known as Proliferation-Induced Lymphocyte-Associated Receptor (PILAR), which is crucial for a robust expansion of human lymphocytes. PILAR is markedly up-regulated on both CD4 and CD8 T cells upon TCR engagement and increases the expression of anti-apoptotic genes and glucose transporters through CD161, which globally results in a dramatic enhancement of T cell proliferation. Agents which stimulate or block this activity are also provided as are methods for manipulating PILAR signaling in the treatment of disease.

Abstract: Novel tricyclic-bis-enone derivatives (TBEs) as well as the process for the preparation of such TBEs are provided. Also provided are methods for prevention and/or treatment of cancer, Alzheimer's disease, Parkinson's disease, multiple sclerosis, amyotropic lateral sclerosis, rheumatoid arthritis, inflammatory bowel disease, and all other diseases whose pathogenesis is believed to involve excessive production of either nitric oxide (NO) or prostaglandins or the overexpression of iNOS or COX-2 genes or gene products. Further, methods for the synthesis of the TBE compounds of the invention utilize cheap commercially available reagents and are highly cost effective and amenable to scale-up. Additional high efficiency synthetic methods that utilize novel intermediates as well as the synthesis of these intermediates are also provided. Furthermore, the invention also provides methods for designing novel and water-soluble TBEs.

Abstract: This invention describes novel tricyclic-bis-enone derivatives (TBEs), such as TBE-31, TBE-34, TBE-45 and water-soluble TBEs. The methods of preparing these compounds are also disclosed. The inventors demonstrate the ability of these new TBEs to inhibit proliferation of human myeloma cells, inhibit the induction of iNOS in cells stimulated with interferon-?, induce heme oxygenase-1 (HO-1), induce CD11b expression—a leukemia differentiation marker, inhibit proliferation of leukemia cells, induce apoptosis in human lung cancer, and induce apoptosis in other cancerous cells. The TBEs of this invention are expected to be useful agents for the treatment and prevention of many diseases, including cancer, neurological disorders, inflammation, and pathologies involving oxidative stress.

Abstract: The present invention is a method for synthesizing furanosteroids. The method involves intramolecular Diels-Alder/retro-Diels-Alder reaction and tautomerization of a functionalized alkyne oxazole to produce a furo[2,3-b]phenol derivative which is elaborated by intermolecular and intramolecular condensations to generate ring-A of the furanosteroid. Furanosteroids and pharmaceutical compositions containing the same are also provided.

Abstract: A system and method for inverting a cubical device 100 that inverts one or more faces of the cubical device 100 in a single fluid motion. In an embodiment, the cube faces are split in two face piece assemblies 210, in an alternative embodiment faces have only one invertible section 802, 702. The face piece assemblies 210 are initially held by cubical device 100 with a particular side facing inward. Operating the cubical device 100 causes one or more face piece assemblies 210, 803 to expand out from the center point of the cubical device 100, to rotate, and then collapse inward until cubical device 100 is reformed with the particular side of the faces in an outward-facing orientation. The joints, links and gears in the mechanism restrict the degrees of freedom to one such that the entire inversion movement is coupled. Multiple applications are proposed for the device, and embodiments having actuators for driving the inversion are disclosed.

Abstract: The present invention relates to mutant proline-and-arginine rich (PR) peptides with defined structural characteristics for use in inhibiting mammalian 20S proteasome activity and modulating expression of genes regulating the NF-?B pathway. Mutant PR peptides of the present invention differ from wild-type PR peptides by having at least one to three amino acid substitutions, wherein at least one of the amino acid residues at position one, two or three of the mutant PR peptide is positively charged.

Abstract: Optical tomography systems that provide light of multiple distinct wavelengths from a plurality of sources are described. The systems direct light into mammalian tissue, and light from the mammalian tissue is collected at a plurality of reception points. Collected light from each reception point is separated according to its wavelength, and received by a photodetector to produce path attenuation signals representing attenuation along paths between the source locations and the reception points. An image construction system generates a tomographic image of the mammalian tissue from the path attenuation signals. One embodiment of an optical imaging system includes an optical coherence tomography-near infrared probe. The systems and methods may utilize a spectral derivative approach that provides insensitivity to the boundary and boundary artifacts in the signal, thereby improving the quality of the reconstructed images.

Abstract: A knot tying system is presented containing a feeding mechanism, a knot tying device, and a clamp. The feeding mechanism has a drive roller and an idle roller capable of guiding a wire. A truck is connected to the end of the wire, and fed into a guide track, fixed relative to the feeding mechanism. The guide track provides a curved track in the shape of a knot desired. The track has a tube having a wire extraction slot running along the length of the tube, an intersection region where an outer portion of the guide track intersects an inner portion of the guide track, and a slit through the inner portion of the guide track substantially at the intersection region. A sensing and control system may also be present.
