摘要:
Chemical functionalization of solid-state nanopores and nanopore arrays and applications thereof. Nanopores are extremely sensitive single-molecule sensors. Recently, electron beams have been used to fabricate synthetic nanopores in thin solid-state membranes with sub-nanometer resolution. A new class of chemically modified nanopore sensors are provided with two approaches for monolayer coating of nanopores by: (1) self-assembly from solution, in which nanopores −10 nm diameter can be reproductibly coated, and (2) self-assembly under voltage-driven electrolyte flow, in which 5 nm nanopores may be coated. Applications of chemically modified nanopore are provided including: the detection of biopolymers such as DNA and RNA; immobilizing enzymes or other proteins for detection or for generating chemical gradients; and localized pH sensing.

The invention relates to sulphated polysaccharides which have the general structure of the constituent polysaccharides of heparin and which have a molecular weight of less than 8000 Daltons, comprising two antithrombin III-binding hexasaccharide sequences corresponding to formula (I) in which: R1 represents an OH group when the hexasaccharide of formula (I) is located at the reducing end of the polysaccharide, or else R1 represents a bond with another saccharide unit of said polysaccharide; R2 represents a hydrogen atom when the hexasaccharide of formula (I) is located at the non-reducing end of the polysaccharide, in which case the bond between carbon atoms 4 and 5 of the first saccharide unit of said hexasaccharide is a double bond, or else R2 represents a bond with another saccharide unit of said polysaccharide, in which case the bond between carbon atoms 4 and 5 of the first saccharide unit is a single bond. Preparation thereof, use thereof as antithrombotic medicaments, and also use thereof in a method for analyzing a sample of a heparin derivative.

Disclosed herein are methods and tests for diagnosing and/or monitoring a metabolic condition such as diabetes in a subject, wherein the methods and tests measure salivary glycoproteins. Some of the methods are based on the oxidation of glycoproteins in a saliva sample from the subject, for example using sodium metaperiodate, and then detecting the aldehydes generated during oxidation using a chemical detection method. Also disclosed are kits and lateral flow devices for detecting glycoproteins in a saliva sample.

This study describes a method to determine the likelihood of the development of metastasis in a subject suffering from cancer, in addition to a method to design a customized therapy in a subject suffering from cancer, in particular breast, colon, lung, kidney and thyroid cancer, based on the determination of the expression level of one or more genes whose expression is modulated by an increase in c-MAF expression. It also describes a method for the identification of marker genes with a propensity for metastatic cancer based on inducing the modulation of the c-MAF expression Finally, the use of PTHLH and PODXL inhibitors and RERG activators in the treatment and/or prevention of the cancer, in particular breast, colon, lung, kidney and thyroid cancer.

[Object] A method of detecting nucleic acids easily without requiring complicated operations such as mixing of liquids and cleaning within micro-scale flow channels. [Solving Means] A method of detecting nucleic acids including the steps of bringing a sample containing the nucleic acids into contact with copper, and detecting fluorescence emitted from the sample is provided. According to the method of detecting nucleic acids, only by bringing the sample containing nucleic acids into contact with copper, the fluorescence derived from the composite of the nucleic acids and copper can be easily detected.
摘要:
Encoded bead multiplex assays for chromosomal gains and losses are provided that provide the benefits of complex, large template DNA sources, such as BAC DNA, as the probe material without bead networking or other assay performance problems. Reagents for assaying DNA are described herein which include a plurality of encoded particles having attached amplicons amplified from a template DNA sequence. Each individual attached amplicon includes a nucleic acid sequence identical to a random portion of the template DNA sequence, wherein the amplicons together represent substantially the entire template DNA and wherein the nucleic acid sequence identical to a random portion of the template DNA sequence of each individual amplicon is shorter than the entire template DNA.
