摘要:
According to the inventive method for applying substances to a support, especially monomers for the combinatorial synthesis of molecule libraries, the substances are first embedded in a matrix consisting of at least one solvent, said solvent being in a solid state of aggregation at a temperature below 90 °C, preferably below 50 °C. The substances that are embedded in the matrix form transport units which are subsequently applied to the support in a solid state of aggregation, at a temperature below 90 °C, preferably below 50 °C. Alternatively, the transport units can be dissolved with a second solvent part and applied to the support in a liquid state of aggregation, where they adopt a solid or gel-like stage of aggregation after said solvent part has completely or partially evaporated. The substances on the matrix are then mobilised by modifying their physical environment and brought into the vicinity of the support surface through a physical process. Here, the substances link up with the molecules. This method can be repeated to apply multiple layers to the support in precise positions. The method can be carried out using a device which essentially has the structure of a laser printer or a laser copier or an ink-jet printer.

The present invention relates to the use of inhibitors of the CD95 ligand/receptor system for the manufacture of a medicament for the treatment of neurological disorders or injuries in a mammal, particularly for the treatment of spinal cord injury, more particularly for the treatment of paraplegia.
摘要:
Described is a conjugate comprising (a) an amphiphilic transport peptide of human origin as a transmembrane module (TPU), (b) a nuclear localization sequence (NLS) and (c) a signalling and/or drug carrying module (SM), preferably comprising Gd, Ga, Fe, Mn, I and/or F as (diagnostic) image creating compound. Said conjugate is useful for diagnostic purposes, e.g., for cell tracking by MRI, as a contrast agent (e.g., replacing a "biopsy clip") for MRI, or for determining the activity of DNA repair enzymes by MRI. Said conjugate is also useful for therapy, e.g., for chemotherapy or intranuclear Gadolinium Neutron Capture Therapy (GNCT). The transmembrane module (TPU) is selected among peptides of human origin, whose amino acid sequences are similar to the sequence of the antennapedia fragment RQIKIWFQNRRMKWKK. In a specific embodiment, TPU is derived from the human homeobox protein HOX-B1. The nuclear localization sequence (NLS) is derived from the simian virus 40-T antigen or from a transcription factor.
摘要:
The present invention refers to a method for reprogramming a recipient cell, the method comprising, first, contacting the recipient cell with the cytoplasm of a donor cell from an amphibian or from a bony fish and, second, detecting the expression of embryonic markers in the recipient cell. Furthermore, the present invention contemplates the therapeutic use of the disclosed method for diseases requiring the replacement or renewal of cells.
摘要:
The present invention therefore provides a screening method for the identification and characterization of inhibitors of DNA methyltransferases comprising the following steps:
a) generation of at least one Drosophila culture
which culture comprises at least one offspring that is derived from a cross between flies of the Drosophila strains GawB(69B) and UAS-Dnmt3a and in an appropriate developmental stage, a sufficient amount of Drosophila medium and an appropriate concentration of at least one candidate compound for a DNA methyltransferase inhibitor,
b) incubation of the the Drosophila culture of step a) under incubation conditions which allow normal Drosophila development for an appropriate incubation period, c) identification of those Drosophila cultures of step b) that show the presence of mobile larvae or pupae.
In another aspect, the invention concerns the offsprings derived from a cross between the transgenic Drosophila strains GawB(69B) and UAS-Dnmt3a , as well as their use for the identification and characterization of inhibitors of DNA methyltransferases, particularly of inhibitors of Dnmt3a.
摘要:
The present invention relates to peptides which interact with IAPs. IAPs are highly expressed in tumor cells which fail to undergo apoptosis. By binding to IAPs, the peptides of the present invention release tumor cells from the apoptosis block and thus provide a new tool for effective cancer therapy.
摘要:
The invention relates to a cage rack system (1) with forced ventilation. Each cage (2) in said system is connected to a ventilation unit (3) which is configured in such a way that the cages (2) can be flushed for ventilation in a low pressure mode or an overpressure mode. The aim of the invention is to provide a cage rack system (1) of this type that is more simple, more economical and more easy to handle and transport and which has a high level of operational reliability. To this end, the ventilation unit (3) has only one pump (4) with a drive (5) and is configured in such a way that a conveying direction (6 or 7) can be adjusted to or from the cages (2).
摘要:
The present invention relates to the identification and use of target genes for the detection and treatment of drug-resistant tumor cells. The nucleic acids of the present invention exhibit a deregulated phenotype when the tumor cells are subjected to cytostatic drugs, i.e. they are expressed in a higher or lower amount as compared to parental drug-sensitive cancer cells. Thus, they can be used as a diagnostic and pharmaceutical tool to render drug-resistant cells drug-sensitive. In addition, the present invention includes the polypeptides encoded by the respective nucleic acids, expression vectors harboring the nucleic acids, host cells for expression and methods for the diagnosis and treatment of drug-resistant tumor cells.
