A worktop or a furniture unit incorporating the sheet, and to a method for mounting accessories or elements that are to be added to said sheet.

Abstract: The present invention relates to compounds suitable as modulators of protein misfolding and/or protein aggregation. The compounds are particularly suitable as inhibitors of amyloid aggregate formation and/or modulators of amyloid surface properties, and/or as activators of degradation or reduction of amyloid aggregates.

Abstract: The present invention refers to analogues of 1,3-bis(4-nitrophenyl)triazenes, their pharmaceutically acceptable salts and N-acyl derivatives for the treatment of different types of tumors. Said compounds show cytotoxicity at very low concentrations (IC50 0.22 to 12.8 ?M), and good solubility. These compounds can be used in the treatment of tumor patients as single drugs or in combination with other cytostatics.

Abstract: The present invention relates to methods for the preparation of chemically aminoacylated tRNAs for the purpose of introduction of markers into nascent proteins. The present invention also relates to methods for the non-radioactive labeling, detection, quantitation and isolation of nascent proteins translated in a cellular or cell-free translation system utilizing chemically aminoacylated tRNAs. tRNA molecules are misaminoacylated with non-radioactive markers which may be non-native amino acids, amino acid analogs or derivatives. Markers may comprise cleavable moieties, detectable labels, reporter properties wherein markers incorporated into protein can be distinguished from unincorporated markers, or coupling agents which facilitate the detection and isolation of nascent protein from other components of the translation system.

Abstract: Materials for optical recording media are disclosed. Specifically, the materials are metal chelate compounds of azo dyes, which are formed from sulfamoylated m-diaminobenzene compounds and benzene ring-containing azo compounds. Further, the invention provides an optical recording medium, characterized in that said metal chelate compounds of azo dyes are employed onto the optical recording medium to form a recording layer. The invention also discloses a process for the production of an optical recording medium.
