Abstract: The invention relates to a contour collimator for radiotherapy, comprising a plurality of plate-shaped diaphragm elements provided in a guiding block and movably arranged with respect to one another to form a contour diaphragm for a radiation beam emitted by a radiation source towards the collimator, and at least one drive for moving the diaphragm elements, wherein a drive of its own is associated with each diaphragm element, the drives of a group of diaphragm elements are arranged substantially adjacent to one another, and the drive is a linear motor, wherein each linear motor comprises a linearly movable rod directly fixed to the associated diaphragm element. The invention facilitates a design of a contour collimator with a shape being as compact as possible, and wherein both precise and stable adjustability of the diaphragm elements is achieved without a backlash. In this way improvements to contour collimators are provided.

Abstract: The invention relates to tumour therapy. In one aspect, the present invention relates to conjugates of a toxin and a target-binding moiety, e.g. an antibody, which are useful in the treatment of cancer. In particular, the toxin is an amatoxin, and the target-binding moiety is preferably directed against tumour-associated antigens. In particular, the amatoxin is conjugated to the antibody by linker moieties. In particular the linker moieties are covalently bound to functional groups located in positions of the amatoxin proved as preferred positions for the attachment of linkers with respect to optimum antitumor activity. In a further aspect the invention relates to pharmaceutical compositions comprising such target-binding moiety toxin conjugates and to the use of such target-binding moiety toxin conjugates for the preparation of such pharmaceutical compositions. The target-binding moiety toxin conjugates and pharmaceutical compositions of the invention are useful for the treatment of cancer.
Abstract: The present invention relates to the use of Rspondins, particularly Rspondin2 (Rspo2) or Rspondin3 (Rspo3) or Rspondin nucleic acids, or regulators or effectors or modulators of Rspondin, e.g. Rspo2 and/or Rspo3 to promote or inhibit angiogenesis and/or vasculogenesis, respectively. The invention is based on the demonstration that Rspo3 and Rspo2 are angiogenesis promoters, and the identification of Rspo2 and 3 as positive regulators of vascular endothelial growth factor (VEGF). These results indicate a major role for Rspondins, particularly Rspo3 and/or Rspo2 in the signaling system during angiogenesis. The invention also relates to the use of regulators or effectors or modulators of Rspondin3, including agonists and antagonists, in the treatment of conditions where treatment involves inhibiting or promoting angiogenesis and/or vasculogenesis.

Abstract: The present invention relates to the finding that Syndecans (Sdc) are receptors of Rspondin-2 (Rspo2) and Rspondin-3 (Rspo3). Thus, the present invention relates to the identification of Rspo2, Rspo3 and/or Sdc activity modulators by determining if a test compound has the ability to modulate the binding of an Rspo2 and/or Rspo3 polypeptide to an Sdc polypeptide. Further, the invention refers to novel uses for antagonists of Rspo2 and/or Rspo3 in the treatment of Sdc-associated disorders and for Sdc antagonists in the treatment of Rspo2- and/or Rspo3-associated disorders.

Abstract: In summary, the present invention concerns a method for multiple orthogonal labelling of oligonucleotides, preferably RNA or DNA, by simultaneously performing the inverse Diels-Alder reaction (DAinv) and the copper-catalyzed click reaction (CuAAC), wherein the method is employed in a single step by just adding the different reaction components together and incubating the aqueous reaction mixture preferably for one hour at room temperature. In detail, the reaction components are one or more N3-modified labels, a copper compound, a stabilizing ligand, a reducing agent and one or more electron-deficient label-modified dienes that are added together with an at least double-modified oligonucleotide having one more nucleotides containing one or more N3-reactive groups and one or more electron-rich dienophiles, wherein a terminal alkyne moiety is preferably used as N3-reactive group(s) and a frans-cyclooctene moiety or norbornene is preferably used as electron-rich dienophile(s), more preferably frans-cyclooctene.
