摘要:
Disclosed is a method for promptly identifying a liver disease. A normal person or a liver disease such as drug-induced liver injury, asymptomatic hepatitis B carrier, chronic hepatitis B, hepatitis C with persistently normal ALT, chronic hepatitis C, cirrhosis type C, hepatocellular carcinoma, simple steatosis, or non-alcoholic steatohepatitis is identified by measuring the concentration of a γ-Glu-X (wherein X represents an amino acid or an amine) peptide or the level of AST or ALT in blood and carrying out, for example, a multiple logistic regression based on the measured value.
摘要:
Disclosed is a novel NASH marker for use in a method for detecting NASH or evaluating the severity of NASH, which utilizes at least one factor selected from the group consisting of an IL-1 receptor antagonist, sCD40, HMGB1, sPLA2 group IIA and an sPLA2 activity as the marker. Also disclosed is a method for detecting NASH or evaluating the severity of NASH in a subject, which utilizes the marker.
摘要:
The present invention relates to a novel form of core+1 protein of Hepatitis C virus (HCV), designated shorter form core+1 protein. The shorter form core+1 protein of Hepatitis C virus is the product of translation of a coding sequence consisting of all or part of a nucleotide sequence extending from nucleotide 598 to nucleotide 920 within the core+1 ORF of HCV represented on FIG. 3B. The invention also provides methods for detecting infection by Hepatitis C virus in biological samples, methods of screening compounds which interact with viral propagation in HCV infected cells or screening of compounds impaction on the expression of shorter form core+1 protein and uses of these compounds for the preparation of compositions useful for their anti-viral activities.

摘要:
A novel use of GRP 94 in treatment of virus infection is provided. More specifically, a method of inhibiting virus infection by inhibiting expression of GRP 94 and/or inactivating activity of GRP 94, and a method of developing drugs for preventing and/or treating virus infection and/or diseases caused by virus infection by using GRP 94 as a target are provided.
摘要:
The invention relates to a method for the in vitro diagnostic detection of an infection with a microorganism, comprising placing a biological sample, in a single assay receptacle, in the presence of particles, each carrying at least one specific detectable physical parameter, and belonging to at least two different groups, one of the groups carrying an anti-IgM capture antibody and the other group carrying a capture antigen derived from said microorganism.

Provided is a method for determining the presence or absence of a pathogen in a sample, which method comprises: a) contacting the sample with a whole or a part of a cell surface receptor protein capable of binding the pathogen; b) allowing the cell surface receptor protein or part thereof to bind the pathogen; c) determining the presence or absence of the pathogen bound to the receptor protein or part thereof.
摘要:
The present invention provides an assay for the detection of the NS2/3 cleavage products NS2 or NS3 in the presence of uncleaved NS2/3. Following self-cleavage of NS2/3 to generate NS2 and NS3 cleavage products, a sample is incubated with a ligand specific for the recognition of NS2 or NS3 cleavage product in the presence of uncleaved NS2/3. There is provided a method for detecting a NS2/3 autocleavage product in a sample containing NS2/3 protease, whereby the amount of bound ligand detected correlates with the NS2/3 autocleavage activity. A further aspect of the present invention concerns ligands selectively recognizing one of the NS2 cleavage product or the NS3 cleavage product with minimal cross-reactivity with the uncleaved NS2/3 and the other cleaved product. The present invention provides antibodies that selectively recognize one of cleaved NS2 product or cleaved NS3 product with minimal cross-reactivity with the uncleaved NS2/3 and the other cleaved product.
