Abstract:
Die Erfindung betrifft eine Sonde (1) zur enteralen Ernährung eines Patienten, mit einem zumindest abschnittsweise entlang einer Axialrichtung (S) erstreckten Schlauchabschnitt (16), der ein proximales Ende (161) und ein distales Ende (160) aufweist, und einer an dem distalen Ende (160) des Schlauchabschnitts (16) angeordneten Rückhaltevorrichtung (12, 13), die in einem gestauchten Zustand das distale Ende (160) des Schlauchabschnitts zumindest in einer Richtung radial zur Axialrichtung (S) überragt und in einem gestreckten Zustand, in dem die Rückhaltevorrichtung (12, 13) entlang der Axialrichtung (S) gestreckt ist, eine im Vergleich zum gestauchten Zustand radial geringere Ausdehnung aufweist. Die Rückhaltevorrichtung (12, 13) ist in Zusammenwirken mit einer Betätigungsvorrichtung (2) von dem gestauchten Zustand in den gestreckten Zustand überführbar. Dabei ist vorgesehen, dass der Schlauchabschnitt durch einen Außenschlauch (16) ausgebildet und innerhalb des Außenschlauchs (16) ein proximales Ende (151) und ein distales Ende (150) aufweisender Innenschlauch (15) angeordnet ist, wobei der Innenschlauch (15) mit seinem distalen Ende (150) mit dem Betätigungsstück (10) verbunden ist und entlang der Axialrichtung (S) derart elastisch ist, dass das Betätigungsstück (10) gegenüber dem Außenschlauch (16) entlang der Axialrichtung (S) zum Überführen der Rückhaltevorrichtung (12, 13) vom gestauchten Zustand in den gestreckten Zustand bewegbar ist. Auf diese Weise wird eine Sonde zur enteralen Ernährung eines Patienten geschaffen, die ein einfaches Legen und einen einfachen Austausch der Sonde ermöglicht.

Abstract:
The invention provides chimeric capture probes immobilizable via an L-nucleic acid tail that can bind to a complementary L-nucleic acid in an immobilized probe. The capture probes are useful for capturing a target nucleic acid from a sample. The L-nucleic acid in the tail of the capture probe bind to the complementary L-nucleic acid in the immobilized probe with similar affinity as would otherwise equivalent D-nucleic acids. However, the L-nucleic acid of the capture probe tail and immobilized probes do not form stable duplexes with D-nucleic acids present in the in the sample containing the target nucleic acid. Binding of nucleic acids in the sample directly to immobilized probe or to the tail of the capture probe is reduced or eliminated increasing the sensitivity and/or specificity of the assay.
Abstract:
The invention relates to a mixture of plate-type, copper-containing metal effect pigments having a copper content of between 60 and 100 wt. % in relation to the entire metal content, said mixture comprising at least one other component. The copper-containing metal effect pigments have a thickness distribution determined by means of a thickness calculation using raster electron microscopy (REM), in the form of a cumulative passage distribution, with a) a h50 value of between 10 and 100 nm, and b) a h90 value of between 20 and 150 nm; and the at least one other component is a cellulose derivative selected from the group consisting of alkyl cellulose, hydroxyalkyl cellulose, alkyl(hydroxyalkyl)cellulose and mixtures thereof, and/or at least one additive with antioxidative and/or radical-inhibiting properties. The invention also relates to a method for producing said mixture and to a coating agent.
Abstract:
Novel methods of synthesizing multiple copies of a target nucleic acid sequence which are autocatalytic are disclosed (/. e., able to cycle automatically without the need to modify reaction conditions such as temperature, pH, or ionic strength and using the product of one cycle in the next one). In particular, methods of nucleic acid amplification are disclosed which are robust and efficient, while reducing the appearance of side-products. In general, the methods use priming oligonucleotides that target only one sense of a target nucleic acid, a promoter oligonucleotide modified to prevent polymerase extension from its 3 '-terminus and, optionally, a means for terminating a primer extension reaction, to amplify RNA or DNA molecules in vitro, while reducing or substantially eliminating the formation of side-products. The disclosed methods minimizes or substantially eliminate the emergence of side-products, thus providing ahigh level of specificity. Furthermore, the appearance of side-products can complicate the analysis of the amplification reaction by various molecular detection techniques. The disclosed methods minimize or substantially eliminate this problem, thus providing enhanced levels of sensitivity.
Abstract:
Methods for capturing a target nucleic acid from a sample by using a capture probe that binds nonspecifically to the target nucleic acid and binds specifically to an immobilized probe via a specific binding pair that has one member on the capture probe and one member on the immobilized probe are disclosed. Compositions that include a capture probe that binds nonspecifically to a target nucleic acid and specifically to an immobilized probe via binding of members of a specific binding pair in a solution phase of a reaction mixture are disclosed.
Abstract:
The present invention provides nucleic acid amplification methods that desirably reduce or eliminate false positive amplification signals resulting from contaminating biological material, e.g., nucleic acid, that may be present in one or more reagents used in an amplification reaction and/or that may be present in the environment in which an amplification reaction is performed. The invention offers the further advantage of requiring less stringent purification and/or sterility efforts than conventionally needed in order to ensure that enzymes and other reagents used in amplification reactions, and the environment in which an amplification reaction is performed, are free of bacterial or other nucleic acid contamination that may yield false positive results.
Abstract:
The present invention is directed to novel methods of synthesizing multiple copies of a target nucleic acid sequence which are autocatalytic (i.e., able to cycle automatically without the need to modify reaction conditions such as temperature, pH, or ionic strength and using the product of one cycle in the next one). In particular, the present invention discloses a method of nucleic acid amplification which is robust and efficient, while reducing the appearance of side-products. The method uses only one primer, the "priming oligonucleotide," a 3'blocked promoter oligonucleotide and optionally, a means for terminating a primer extension reaction, to amplify RNA or DNA molecules in vitro, while reducing or eliminating the formation of side-products. The method of the present invention minimizes or eliminates the emergence of side-products, thus providing a high level of specificity. Furthermore, the appearance of side-products can complicate the analysis of the amplification reaction by various molecular detection techniques. The present invention minimizes or eliminates this problem, thus providing an enhanced level of sensitivity.
Abstract:
Methods for efficiently capturing a target nucleic acid from a sample by using a mixture that contains a capture probe specific for the target nucleic acid, the target nucleic acid, and a denaturant chemical, which mixture is incubated at elevated temperature for a short time, are disclosed. Compositions that include a capture probe that specifically binds to a target nucleic acid and a denaturant chemical, which when mixed with the target nucleic acid and incubated at elevated temperature for a short time, promote efficient hybridization of the capture probe and target nucleic acid are disclosed.
