A self-timed sense amplifier read buffer pulls down a pre-charged high global bit line, which then feeds data into a tri state write back buffer that is connected directly to the bit line.

US08476436B1 Method for enhancing luminescence intensity of clytin-II
A method for enhancing a luminescence activity of clytin-II is provided. A codon-optimized nucleic acid is used for coding the apo-clytin-II protein, and the luminescent activity of the clytin-II is remarkably enhanced when comparing with the conventional use of the wild-type clytin-II.
US08476433B2 Agent exhibiting the properties of a cognitive function promoter (embodiments)
The present invention relates to the field of chemical-pharmaceutical industry and medicine. An agent, exhibiting the properties of a cognitive function promoter, was selected from 1,3-dimethyl-5-[(4-pyridylamino)methylene]barbituric acid and 4-amino-1-(3-nitro-2-oxo-1-pheny-1,2-dihydro-1,6-naphthyridin-5-yl)pyridinium chloride. The compounds, that are proposed as agents, exhibit potent biological activity.
US08476429B2 Tri-, tetra-substituted-3-aminopyrrolidine derivative
An intermediate for production of a quinolone synthetic antibacterial agent and a therapeutic agent for an infection which exhibit broad spectrum and strong antibacterial activity for both Gram positive and Gram negative bacteria.
US08476423B2 Antisense oligonucleotides for inducing exon skipping and methods of use thereof
An antisense molecule capable of binding to a selected target site to induce exon skipping in the dystrophin gene, as set forth in SEQ ID NO: 1 to 202.
US08476416B2 Modulation of immunostimulatory activity of immunostimulatory oligonucleotide analogs by positional chemical changes
The invention relates to the therapeutic use of oligonucleotides or oligonucleotide analogs as immunostimulatory agents in immunotherapy applications. The invention provides methods for enhancing the immune response caused by immunostimulatory oligonucleotide compounds.
US08476414B2 Substrates and internal standards for mass spectrometry detection
An inventive substrate is provided which includes a substrate compound of formula A—B1—B2—B3: wherein A is a sugar moiety; B1 is a linker moiety allowing the conjugation of moiety A and the remaining structure of the substrate; B2 contains a permanently charged element such as a quaternary ammonium group so as to increase proton affinities and ionization efficiencies for mass spectrometry detection efficiencies analysis; and B3 of various carbon length conferring specificities to targeted enzymes. Also provided is a process to detect lysosomal diseases by contacting a sample with the inventive substrate along with an internal standard which is isotope-labeled analog of the product cleaved by a targeted enzyme upon the substrate.
US08476412B2 Selective heated extraction of proteins from intact freshwater algal cells
Methods for selective extraction and fractionation of algal proteins from an algal biomass or algal culture are disclosed. A method of selective removal of products from an algal biomass provides for single and multistep extraction processes which allow for efficient separation of algal proteins. These proteins can be used as renewable sources of proteins for animal feedstocks and human food. Further, lipids remaining in the algal biomass after extraction of proteins can be used to generate renewable fuels.
