  • Publication number: 20070160630
    Abstract: The present invention relates to a polynucleic acid composition comprising or consisting of at least one polynucleic acid containing 8 or more contiguous nucleotides corresponding to a nucleotide sequence from the region spanning positions 417 to 957 of the Core/E1 region of HCV type 3; and/or the region spanning positions 4664 to 4730 of the NS3 region of HCV type 3; and/or the region spanning positions 4892 to 5292 of the NS3/4 region of HCV type 3; and/or the region spanning positions 8023 to 8235 of the NS5 region of the BR36 subgroup of HCV type 3a; and/or the coding region of HCV type 4a starting at nucleotide 379 in the core region; and/or the coding region of HCV type 4; and/or the coding region of HCV type 5, with said nucleotide numbering being with respect to the numbering of HCV nucleic acids as shown in Table 1, and with said polynucleic acids containing at least one nucleotide difference with known HCV type 1, and/or HCV type 2 genomes in the above-indicated regions, or the complement thereof.

  • Publication number: 20070128221
    Abstract: New styles of hepatitis C virus (HCV), referred to as HCV-3 and HCV-4, have been identified and sequenced. Antigenic regions of HCV-2, HCV-3 and HCV-4 polypeptides have been identified. Immunoassays for HCV and antibodies thereto are described, which allow more complete screening of blood samples for HCV, and allow HCV genotyping.

  • Patent number: 6750248
    Abstract: Methods for preparing an estrogenic preparation and isolating estrogenic compounds from a plant, such as an Epimedium plant, are provided. Also provided are estrogenic compounds from Epimedium plant that have been isolated and characterized, and methods for their use in modulating estrogen receptors and in treating conditions mediated by estrogen receptors, such as menopause and estrogen-dependent cancers. Also provided are preparations from Epimedium that are enriched for estrogenic compounds, and methods for their use in modulating estrogen receptors and preventing and treating conditions that are mediated by estrogen receptors.
