  • Patent number: 8906444
    Abstract: A method for modifying silk polymer by coupling a chemical moiety to a tyrosine residue of a silk polymer is described herein for the purpose of altering the physical properties of the silk protein. Thus, silk proteins with desired physical properties can be produced by the methods described herein. These methods are particularly useful when the introduction of cells to a mammal is desired, since modifications to the silk protein affect the physical properties and thus the adhesion, metabolic activity and cell morphology of the desired cells. The silk protein can be modified to produce, or modify, a structure that provides an optimal environment for the desired cells.

  • Publication number: 20140303359
    Abstract: Disclosed is a method for selective synthesis of 1,2-cis-?-linked glycosides which does not require the use of the specialized protecting group patterns normally employed to control diastereoselectivity. Thioglycoside acceptors can be used, permitting iterative oligosaccharide synthesis. The approach eliminates the need for lengthy syntheses of monosaccharides possessing highly specialized and unconventional protecting group patterns.

  • Publication number: 20140221456
    Abstract: Disclosed herein is a method for activating a dormant epithelial stem cell, or population thereof, to a state of multipotency comprising, reducing the level of ?Np63 in the cell(s). The dormant epithelial stem cell(s) may be a horizontal basal cell (HBC) of the olfactory epithelium and the level of ?Np63 may be reduced by contacting the cell or population with an effective amount of one or more agents that downmodulate ?Np63. One example of an agent is an RNAi. Also disclosed is a method for treating olfactory dysfunction in a subject, comprising activating HBCs of the subject by reducing the level of ?Np63 in one or more HBCs of the subject, to thereby treat the olfactory dysfunction. Activated horizontal basal cell (HBCs) are also disclosed.

  • Patent number: 8772456
    Abstract: The claimed invention provides a fusion polypeptide comprising a fibrous protein domain and a mineralization domain. The fusion is used to form an organic-inorganic composite. These organic-inorganic composites can be constructed from the nano- to the macro-scale depending on the size of the fibrous protein fusion domain used. In one embodiment, the composites can also be loaded with other compounds (e.g., dyes, drugs, enzymes) depending on the goal for the materials, to further enhance function. This can be achieved during assembly of the material or during the mineralization step in materials formation.

  • Publication number: 20140159571
    Abstract: A microplasma generator includes first and second conductive resonators disposed on a first surface of a dielectric substrate. The first and second conductive resonators are arranged in line with one another with a gap defined between a first end of each resonator. A ground plane is disposed on a second surface of the dielectric substrate and a second end of each of the first and second resonators is coupled to the ground plane. A power input connector is coupled to the first resonator at a first predetermined distance from the second end chosen as a function of the impedance of the first conductive resonator. A microplasma generating array includes a number of resonators in a dielectric material substrate with one end of each resonator coupled to ground. A micro-plasma is generated at the non-grounded end of each resonator. The substrate includes a ground electrode and the microplasmas are generated between the non-grounded end of the resonator and the ground electrode.

  • Publication number: 20140128344
    Abstract: The invention provides compounds and methods for inhibiting proteases. One aspect of the invention features pro-soft inhibitors which react with an activating protease to release an active inhibitor moiety in proximity to a target protease. In certain instances, compounds inhibit proteasomes and/or post-proline cleaving enzymes (PPCE), such as dipeptidyl peptidase IV. The compounds of the invention provide a better therapeutic index, owing in part to reduced toxicity and/or improved specificity for the targeted protease.
