摘要:
Embodiments of the present invention provide polymer matrix nanocomposites reinforced with nano-scale materials such as nanoparticles and carbon nanotubes and methods of fabricating. The nanomaterials are provided within relatively low weight fractions, for example in the range of approximately 0.01 to about 0.4% by weight and distributed within the matrix by a magnetic mixing procedure to provide substantially uniform reinforcement of the nanocomposites. Advantageously, these nanocomposites provide significantly enhanced tensile strength, strain to failure, and fracture toughness over corresponding neat matrices.

The present invention relates to methods and compositions for treating diseases. More specifically, the present invention relates to the administration of multiple drugs as part of a treatment of disease. Specific embodiments of the invention relate to a treatment regimen for neuroblastomas and other N-MYC, c-MYC, and L-MYC amplified and overexpressed tumors, comprising administering multiple therapeutic compounds like DFMO, SAM486A, a verinoid and a cytotoxic drug and placing the patient on a low polyamine diet and/or providing the patient with a polyamine limiting dietary supplement.
摘要:
Embodiments herein include methods and constructs that can be used to co-express two or more polypeptides of interest from a single polynucleotide encoding a precursor polypeptide. Within this precursor polypeptide can reside at least one autonomous processing unit, which can mediate release of flanking polypeptides of interest in cis. The processing unit can include an N-terminal autocatalytic cleavage domain and a C-terminal cleavage domain. Some embodiments include constructs and methods for co-expressing polypeptides without N- or C-terminal overhangs, in any cellular or extracellular location, and/or in stoichiometric ratios.
摘要:
A modified human complement C3 protein (C3) is disclosed comprising a substitution of a portion of a human C3 protein, with a corresponding portion of a Cobra Venom Factor protein (CVF) which results in a human C3 protein with CVF functions, but with substantially reduced immunogenicity. Advantageously, the C3 protein can be manipulated to contain at least one of the following CVF functions: increased stability of the C3 convertase and increased resistance to the actions of factors H and/or I. A large number of hybrid C3 proteins containing substitutions in the C-terminal portion of the alpha chain of C3 are presented and tested for the above functions. Methods of treatment of diseases such as reperfusion injury, autoimmune diseases, and other diseases of increased complement activation are presented as well as methods of increasing the effectiveness of gene therapeutics and other therapeutics.

Provided are nanostructure-containing nanotape materials. The materials may be incorporated at the interface between two other structures to provide strength and toughness at the interface. The materials may also be applied to a standalone structure to provide strength and toughness. Also provided are related methods of fabricating the nanotape materials, as well as gas diffusion membranes and fuel cells that include nanostructured materials.
摘要:
A new class of electronic devices suitable for Si IC incorporation and of diverse utility are described. The devices are useful for many sensing applications as well as for special circuit applications. Sensing applications include chemical and biochemical sensing, photo detection (UV, visible, IR and FIR), magnetic field sensing, electric field sensing, and force sensing. The devices are MEMs compatible. Sensor sensitivity is voltage and current tunable over a wide range. The devices further constitute a new and useful class of IC reference voltage devices. Selective non linear features are also achievable in support of non-linear device applications. These unique devices may be considered as distributed merged bipolar and FET structures. The new distributed channel bipolar devices (DCBDs) have a channel of a selected shape formed in a surface of a substrate by doping or by influencing of a coating. In the device structure, the channel acts as an NPN or PNO BJT collector or emitter.
摘要:
Recombinant subunit proteins derived from the MSP-1 C-terminal region of the parasite Plasmodium falciparum are described that have enhanced immunogenic properties. Selected regions of p33 have been combined with p19 to enhance the immunogenic potential of the p19 core region. As the constructs represent discontinuous segments fused to create unique proteins, the recombinant proteins expressed are not found in nature. The enhanced immunogenic potential of the disclosed recombinant proteins provided for strong, consistent and specific antibody responses. The disclosed recombinant subunit proteins are vaccine candidates for protection against infection with malaria.

摘要:
The present invention relates to methods and compositions to detect analytes in a sample using antibody molecules that are transformed into nanoscale “self-signaling” biosensors. It relates in particular to those methods and compositions that provide for single-step detection of target analytes without the need for labor-intensive steps necessary in conventional assays.
摘要:
The present application relates to the use of metabolically-engineered microbial cells for the production of hydrogen and hydrogenase enzymes. The microbial cells are strains of E. coli which are genetically engineered to optimize the cell for production of hydrogen or active hydrogenase. The strains of E. coli are transformed with at least one expression vector directed towards the biosynthesis of a hydrogenase enzyme. Methods of hydrogen production, fuel-cell systems and recombinant fuel-cell catalysts are also provided.
