    Abstract: The disclosure describes a method for sequencing long portions of DNA sequence by assembling a plurality of shorter polynucleotide reads. Generally, The method includes annealing a plurality of primers to a denatured DNA molecule, appending a barcode polynucleotide to the 5′ end of the primer, subjecting the DNA molecules to a plurality of cycles of (1) pooling, (2) dividing, and (3) appending a barcode polynucleotide to the 5′ end of the primer, sequencing the barcode polynucleotides and the genomic DNA, and assembling the short read polynucleotide sequences having identical barcode polynucleotides.

    Abstract: The present invention is directed to protocells for specific targeting of hepatocellular and other cancer cells which comprise a nanoporous silica core with a supported lipid bilayer; at least one agent which facilitates cancer cell death (such as a traditional small molecule, a macromolecular cargo (e.g. siRNA or a protein toxin such as ricin toxin A-chain or diphtheria toxin A-chain) and/or a histone-packaged plasmid DNA disposed within the nanoporous silica core (preferably supercoiled in order to more efficiently package the DNA into protocells) which is optionally modified with a nuclear localization sequence to assist in localizing protocells within the nucleus of the cancer cell and the ability to express peptides involved in therapy (apoptosis/cell death) of the cancer cell or as a reporter, a targeting peptide which targets cancer cells in tissue to be treated such that binding of the protocell to the targeted cells is specific and enhanced and a fusogenic peptide that promotes endosomal escape of protocells and encapsulated DNA. Protocells according to the present invention may be used to treat cancer, especially including hepatocellular (liver) cancer using novel binding peptides (c-MET peptides) which selectively bind to hepatocellular tissue or to function in diagnosis of cancer, including cancer treatment and drug discovery.

    Abstract: Systems and methods implementing a resonance circuit, including an avalanche photodiode, in which a resonance frequency of the resonance circuit is matched with the frequency of a dynamic biasing signal of the avalanche photodiode, can be used in a variety of applications. In various embodiments, a method for blocking and/or compensating current injection associated with the parasitic capacitance of APDs operated under dynamic biasing may be substantially realized by the matching of the resonance frequency of a resonance circuit including the avalanche photodiode with the frequency of an applied dynamic biasing signal. Additional systems and methods are described that can be used in a variety of applications.
