By a method for measuring 1,5-anhydroglucitol, comprising the steps of: eliminating or converting glucose interfering with the measurement of 1,5-anhydroglucitol and/or a derivative thereof beforehand; and measuring 1,5-anhydroglucitol performed thereafter, wherein such glucose and/or a derivative thereof are/is eliminated or converted in whole blood as such without performing blood cell separation, an enzyme for measuring 1,5-anhydroglucitol is allowed to act on without performing blood cell separation, and 1,5-anhydroglucitol is electrochemically measured, it becomes possible to measure 1,5-anhydroglucitol using a small amount of whole blood without resort to a centrifuge or the like. Accordingly, this measurement method can be applied to rapid measurement of 1,5-anhydroglucitol at bedside or in a medical examination room or to home self-measurement thereof by a patient.

The present invention is concerned with diagnostic means and methods for determining the metastasising potential of solid tumors. More specifically, the present invention relates to a method of diagnosing whether a solid tumor in a subject has metastasising potential comprising the steps of determining in a sample of a subject suspected to suffer from a solid tumor the expression levels of the marker genes GPR109B, DHRS9, and ERRFI-1 and of a reference gene, calculating at least one variable from one or more of said marker genes and a reference gene and comparing the variable to a reference variable whereby it is to be diagnosed whether the solid tumor has metastasising potential. Moreover, the present invention relates to a method of determining whether a therapy against a solid tumor having metastasising potential is successful. Further contemplated are a solid support, diagnostic device and a kit for carrying out the aforementioned methods.

Eine Vorrichtung (1) zum Erzeugen einer Chemolumineszenzstrahlung (16) in Abhänglgkeit von der Bindung mindestens eines in einer zu untersuchenden Probe enthaltenden Liganden (2) an wenigstens einen für den Liganden (2) bindungsspezifischen Rezeptor (12) hat eine Flusszelle (3) mit einer Innenhöhlung. Die Innenhöhlung hat eine Begrenzungswand, auf welcher der wenigstens eine Rezeptor (12) immobilisiert ist. Die Innenhöhlung hat mindestens zwei Kompartimente (5a, 5b, 5c, 5d). In einem ersten Kompartiment (5a) ist ein Feststoff (7) deponiert, der einen mindestens ein Peroxidase-Enzym aufweisenden Marker (8) zum Markieren des Liganden (2) in lyophilisierter Form enthält In einem zweiten Kompartiment (5b) sind mit einem Salz stabilisiertes Luminol und eine Festsubstanz (10) enthalten, die bei einem Kontakt mit Wasser Wasserstoffperoxid freisetzt,

This invention concerns in vitro method for prognosticating the progress of breast cancer, comprising detecting or quantifying the level of 17β-hydroxysteroid dehydrogenase (17HSD) type 1 enzyme in breast tumor tissue sample, wherein the presence of said 17HSD type 1 enzyme is indicative of severe progress of breast cancer. Furthermore, the invention also concerns the use of a 17HSD type 1 enzyme inhibitor for prevention or treatment of breast cancer. This invention concerns also the use of compound A in the manufacture of a pharmaceutically acceptable preparation useful as 17HSD inhibitor.
摘要:
A method for quantitating leukocyte count in a whole blood sample which comprises: mixing the whole blood sample with a surfactant to give a mixture; allowing the mixture to stand for a period of time sufficient for dissolving leukocytes in the whole blood sample and releasing endogenous myeloperoxidase; measuring the concentration of the released myeloperoxidase in the mixture; and quantitating leukocyte count in the whole blood sample based on the concentration of the released myeloperoxidase. Also, a method for measuring the concentration of C-reactive proteins contained in a whole blood sample together with the leukocyte count in the whole blood sample is disclosed.
摘要:
Synthetic antibody derivatives having at least two F regions covalently linked so as to enhance Fc activity for example effector recruitment. The use of such derivatives in the treatment of conditions where killing of cells is required for example cancer therapy. Methods for the preparation of derivatives are also described.
摘要:
A method for evaluating the potential mutagenic activity of a substance which comprises:
(a) culturing cytochrome P-450 induced bacteria from the genus Streptomyces in a culture medium comprising the substance to be evaluated; (b) incubating an amino acid requiring mutant strain of Salmonella typhimurium in the presence of a sample of the bacterial culture from (a); and (c) determining the number of resulting amino acid sufficient revertant colonies.
摘要:
Provided is a compound comprising the structure: (SIG)-(SI-MOD) m . In this compound, SIG is a signaling molecule, SI is a self-immolative structure bound to SIG such that SIG has a reduced signal relative to the signal of SIG without SI, MOD is a moiety bound to SI that is subject to modification by an activator, and m is an integer from 1 to about 10. With this compound, when MOD is modified by an activator, SI is destabilized and self-cleaved from SIG such that SIG generates an increased signal. Also provided is a method of determining whether a sample comprises an activator, using the above-described compound. Additionally provided is a method of determining whether a cell comprises a nitroreductase using the above-described compound where nitroreductase is the activator. Further provided is a method of determining whether a mammalian cell is hypoxic using the above-described compound where nitroreductase is the activator. A method of detecting a microorganism that comprises a nitroreductase, using the above-described compound where nitroreductase is the activator, is also provided. Also provided is a method of identifying nitroreductase in a sample, using the above-described compound where nitroreductase is the activator.
