  • Patent number: 7468257
    Abstract: The invention relates generally to a new functional protein S assay and kit that is based on the ability of endogenous protein S to prolong clotting time. In the assay procedure, a test plasma sample is diluted with protein S deficient plasma, followed by the addition of purified or recombinant tissue factor (pTF or rTF), purified natural or synthetic phospholipid (pPL or sPL) and activated protein C (APC) or protein C activator (PCA). The clotting time is then measured and compared to a standard curve or a normal control.

  • Publication number: 20060057510
    Abstract: Thermally developable materials such as thermographic and photo-thermographic materials include a co-precipitate comprising first and second organic silver salts, the first organic silver salt comprising a silver salt of a nitrogen-containing heterocyclic compound containing an imino group, and the second organic silver salt comprising a silver salt of a mercaptotriazole. The first organic silver salt can be used in the imaging process as a source of reducible silver ions, and the second organic silver salt can be a source of a toning agent. The co-precipitate can be prepared using double-jet precipitation techniques to provide an aqueous dispersion that can be used in imaging formulations.

  • Publication number: 20050095662
    Abstract: The invention relates generally to a new functional protein S assay and kit that is based on the ability of endogenous protein S to prolong clotting time. In the assay procedure, a test plasma sample is diluted with protein S deficient plasma, followed by the addition of purified or recombinant tissue factor (pTF or rTF), purified natural or synthetic phospholipid (pPL or sPL) and activated protein C (APC) or protein C activator (PCA). The clotting time is then measured and compared to a standard curve or a normal control.

  • Patent number: 6680393
    Abstract: This invention relates to a kind of white wax and its manufacturing method, particularly the white wax extracted from animal fat and sebum as a nontoxic, non-hazardous product of superb moistening that enhances skin's elasticity while keeping skin from cracking. The white wax in reference is made of animal fat and sebum, duly crushed after pre-treatment of high-temperature sterilization and deodorization and removal of impurities, allowing the fat and sebum to mix. The mixed raw material is heated after undergoing rapid refrigeration before being minced into sticky colloid when cooled and when squeezed and screened, the sticky discharges gummy matter which, when mixed and neutralized with emulsifying agent, allowing the gummy matter transform from greasy substance into watery white wax.
