  • Publication number: 20240079478
    Abstract: A preparation method of a gallium oxide device based on high-temperature annealing technology and a gallium oxide device are provided. The preparation method includes: preparing a first barrier layer on a surface of a gallium oxide wafer to block an oxygen atmosphere; implementing a patterning process for regulating impurities of the gallium oxide wafer on the barrier layer, a process depth of the patterning process not exceeding a thickness of the barrier layer; annealing the gallium oxide wafer subjected to above treatment in the oxygen atmosphere; removing the barrier layer; and removing a surface layer of the gallium oxide wafer with the barrier layer lifted off. Problems that a local region of a gallium oxide material cannot be treated alone and net carrier concentration in a selective region of the gallium oxide material cannot be regulated with high-temperature annealing technology in the oxygen atmosphere in related art are solved.

  • Patent number: 7700570
    Abstract: The invention provides new methods for modulating specific CMI-inducing cytokines in vivo. Such new methods result in stimulation of the cytokines IL-6, IL-12 MIP-1? and MCP without substantially inducing undesired cytokines. The methods according to the invention are based upon administration of oligonucleotides containing particular structural motifs which lead to specific cytokine induction.

  • Patent number: 6667293
    Abstract: The present invention provides a method of reducing the immunostimulatory effects of certain phosphorothioate oligonucleotides used to treat pathogen-mediated disease states and other medical conditions. Immunostimulatory effects of phosphorothioate oligonucleotides are reduced in accordance with the method of the invention by administering the phosphorothioate oligonucleotide in a therapeutic formulation which includes at least one cyclodextrin to a mammal afflicted with the disease or condition being treated. The immune response of the mammal is also monitored in the method of the invention.

  • Publication number: 20030129605
    Abstract: Bacterial DNA and synthetic oligodeoxynucleotides containing unmethylated CpG-motifs in a particular sequence context activate vertebrate immune cells. We examined the significance of negatively charged internucleoside linkages in the flanking sequences 5′ and 3′ to the CpG-motif on immunostimulatory activity. Cell proliferation and secretion of IL-12 and IL-6 in mouse spleen cell cultures, and spleen weights of mice increased significantly when a non-ionic linkage was placed at least four or more internucleoside linkages away from the CpG-motif in the 5′-flanking sequence. When the non-ionic linkage was placed closer than three internucleoside linkages in the 5′-flanking sequence to the CpG-motif, immunostimulatory activity was suppressed compared with that observed with the unmodified parent oligo.
