  • Patent number: 9416401
    Abstract: The invention is related to a method and test kits for quantitative determination of polynucleotide amounts present in a sample. The test kit comprises organized pools with polynucleotide probes having distinct sizes and optionally provided with tracer tags or primer tags. The probes are allowed to hybridize with affinity tagged analyte polynucleotides from the sample. The result is hybrids, which can be recovered on a separation aiding tool provided with the pair of the affinity tag. After the quantitative release of the probes, the probes are either directly recorded, or if primer tagged, they are amplified and optionally provided with a tracer tag before recording. The invention provides a sensitive and quantitative determination of the amount polynucleotides present in a cell or tissue sample and allows a quantitative assessment of variations in the amounts of polynucleotides as a response to inherent changes or due to external stimuli.

  • Patent number: 9011762
    Abstract: The invention relates to a sintering method for manufacturing structures by sintering. In addition, the invention relates to a sintered product, an electronic module, and new uses. In the method, a particle material containing conductive or semiconductive encapsulated nanoparticles is sintered, in order to increase its electrical conductivity, by applying a voltage over the particle material. In the method, a substrate is typically used, one surface of which is at least partly equipped with a layer containing nanoparticles. The method is based on thermal feedback between the voltage feed and the nanoparticles. The invention permits the manufacture of conductive and semiconductive structures and pieces by sintering at room temperature and at normal pressure.

  • Patent number: 8916942
    Abstract: The invention relates to temperature compensated micro-electro-mechanical (MEMS) resonators (300) preferably made of silicon. Prior art MEMS resonators have a significant temperature coefficient of resonance frequency, whereby it is difficult to achieve a sufficiently good frequency stability. The inventive MEMS resonator has a resonance plate (310) which resonates in Lamé mode. The resonance plate is p+ doped material, such as silicon doped with boron, and the concentration of the p+ doping is such that the plate has a temperature coefficient of resonance frequency near to zero. The tensile stress and the second order temperature coefficient can further be reduced by doping the plate with germanium.

  • Patent number: 8895292
    Abstract: A microfluidic chip device (MCD) and its use for performing miniaturized assays on magnetic microbeads (MMs) are described. The MCD is particularly useful for carrying out miniaturized transcript analysis by aiding affinity capturing (TRAC) assays, including PCR. The MCD comprises at least one reaction chamber with sealable liquid connections and at least one fluidic pillar filter in each chamber. The fluidic pillar filter comprises rods with spacings allowing MMs to pass. The sealable liquid connections feed liquid to the reaction chamber, wherein air bubbles are removed. The liquid stream contacts the MMs, which are manipulated with a magnetic rod. The liquid connections enable trapping of the MMs behind the pillar filters or in the channel, while the liquid is changed.

  • Patent number: 8742095
    Abstract: The present invention relates to a method of manufacturing a cereal bran product containing beta-glucan. According to the method, a plastic mass is formed from cereal bran by means of a thermo-mechanical treatment, and the mass is brought into contact with an enzyme that breaks up beta-glucan, with or without an enzyme that breaks up starch. After inactivating the enzyme, the bran is dried and, when so needed, ground. The cereal bran product manufactured according to the method has an essentially inextensible structure in a water environment. The product is suitable to be added to aqueous foodstuffs or to foodstuffs, the manufacture of which employs water.

  • Patent number: 8597422
    Abstract: The present invention relates to a light, biodegradable, organic pigment and filler, and a method of manufacturing it. According to the present invention, a solution comprising a starch derivative is first prepared by dissolving the starch derivative into a suitable solvent, and, after that, the solution is brought into contact with a non-solvent to precipitate the starch derivative from the solvent, and, as a result, a dispersion is obtained, one which comprises a precipitate consisting of starch derivative and a liquid phase formed of the solvent and the non-solvent, after which the solvent is removed from the liquid phase and the precipitate is separated from the non-solvent and recovered. The present invention can be used to manufacture both a product comprising 100-300 nm spherical particles, which is suitable for use as a pigment, and a coral-like, porous product which is particularly suitable as a filler.

  • Patent number: 8572064
    Abstract: Method/system for visualizing biological information. The system receives a user query relating to biological information and determines which database contains related biological information. A database query is sent to the database and the result indicates biological/chemical entities and relations. A network is created based on the result; biological/chemical entities are mapped to network nodes and relations to network connections. A distance matrix indicates a multi-dimensional distance for several pairs of network nodes. A dimensionality reduction function is adjusted based on a research context, to bias the search toward a relevant focus. The number of dimensions in the distance matrix is lowered by the dimensionality reduction function. Neighbors of a selected node are searched (2-18) based on the distance matrix to elucidate a biological role of the selected node. A re-created network is visualized (2-20) based on the adjusted dimensionality reduction function.
