Abstract: This method and device detects past use of drugs of abuse when the drug substance and its metabolites are no longer present in the body, based on the detection of the antibodies formed in response to said drug, and persist even after this drug and its metabolites are cleared from the body. False positive rate is reduced by screening out subjects with heightened inflammatory state. One embodiment of the invention sets forth the method and device comprising: testing a set of samples for levels of an inflammation biomarker; determining a subset of samples with inflammation biomarker level below a first predetermined threshold; testing samples within the subset of samples for a presence of drug-specific antibodies, for a pre-specified set of drugs; determining which samples within the subset have drug-specific antibody level exceeding pre-specified threshold; and providing an output indicating the samples within the subset having the drug-specific antibodies.

Abstract: To provide a method of accurately detecting pathological haptoglobin using a lectin having strong affinity and high specificity for fucose. The method of the present invention for detecting pancreatic cancer is characterized in that a fucose ?1?6 specific lectin is allowed to act on pathological haptoglobin contained in a sample obtained from a living body, said lectin: (1) being extractede from basidiomycetes, (2) having a molecular weight of 4,000 to 40,000 as determined by the SDS polyacrylamide gel electrophoresis, and (3) having affinity for a fucose ?1?6 sugar chain with a binding constant of 1.0×104 M?1 or more at 25° C.

Abstract: The present invention is related to the discovery that phosphorylation of SP1 (SEQ ID NO.: 2) at serine residue 101 (known herein as phosphoserine101 Sp1) is an important part of a cell's response to DNA damage. This phosphorylation event is important for subsequent Sp1 localization to a site of DNA damage and is correlated with increased cellular viability in response to DNA damage.

Abstract: The invention describes a practical and robust multi-antibody approach to the sensitive immunodetection and determination of the drug of abuse m-chlorophenyl piperazine (mCPP). The invention also describes methods and kits for mCPP detection in an in vitro sample.

Abstract: The present invention relates to novel methods and devices for differentiating in a patient parathyroid diseases, such as hyperparathyroidism and related bone diseases, from normal or non-disease states. One detects whole or non-fragmented (1 to 84) parathyroid hormone in a biological sample and also a large non-whole parathyroid hormone peptide fragment that can function as a parathyroid hormone antagonist. By either comparing values or using independently the value of either the large non-whole parathyroid hormone peptide fragment, the whole parathyroid hormone, or the combination of these values, one is able to differentiate parathyroid and bone related disease states, as well as differentiate such states from normal states.

Abstract: A method of preventing bio-filming during the delivery of photonic energy to a culture or set of organisms in a fluid culture medium, the method including introducing a fluid energy-transfer medium into the fluid culture medium through an interface and distributing light into the fluid energy-transfer medium as it is introduced into the fluid culture medium.

Abstract: Method for the determination of Trichinella infections in an animal or a human, comprising the incubation with Trichinella antigens of a tissue sample taken from the animal or the human, the processing of the tissue sample, the addition of anti-antibodies to the tissue sample, and the verification of whether binding of the anti-antibodies to any antigen/antibody complexes present in the tissue sample has taken place, where the anti-antibodies added are anti-IgG antibodies and simultaneously anti-IgM antibodies.

Abstract: Disclosed is a simple method for detecting a pathological condition of an insulin-resistant disease, particularly type-2 diabetes. The method comprises quantifying the ganglioside GM3 in a blood sample separated from a living body. More specifically, the method comprises the following steps (a) to (c): (a) separating a plasma or serum from the blood collected from a human; (b) quantifying the ganglioside GM3 in the plasma or serum; and (c) comparing the quantified ganglioside GM3 level to the mean ganglioside GM3 level determined in blood samples from healthy volunteers.

The L-fucose ?1?6 specific lectin of the present invention is characterized in that: (1) the lectin is extracted from a basidiomycete or an ascomycete; (2) the lectin has a molecular weight by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of 4,000 to 40,000; and (3) the lectin has an affinity to an L-fucose ?1?6 sugar chain, the affinity being represented by an association constant of 1.0×104M?1 or more (at 25 degrees C.). The lectin can be used for detecting an L-fucose ?1?6 sugar chain specifically, and is effective for the purification of an L-fucose ?1?6 sugar chain or a non L-fucose ?1?6 sugar chain.

Abstract: Cardiovascular disease, e.g., congestive heart failure, is often first diagnosed after the onset of clinical symptoms, eliminating potential for early intervention. The invention provides a multi-marker immunoassay, including cardiac pathology and vascular inflammation biomarkers, yielding a more sensitive assay for early detection of CHF in plasma. A panel consisting of cardiac pathology (cTnI, BNP) and vascular inflammation (IL-6, TNF?, IL-17a) biomarkers provided a sensitivity of 94% for association with CHF.

Methods for determining the capability of a compound to enhance or inhibit the enzymatic activity of a selected protein having phospholipase B enzyme activity employ a protein comprising an activated form of such a pro-phospholipase B (PLB-II) mammalian protein.
