  • Patent number: 11609231
    Abstract: Methods, kits, and active ingredients for diagnosing or treating arthritis or a degenerative disease of the skeletal system, or for selection of subjects for therapy. The methods for diagnosing arthritis involve the detection of an autoantibody, which is associated with arthritis, or excluding the presence of an autoantibody against collagen II. The methods for diagnosing a degenerative disease of the skeletal system, involve the detection of an autoantibody against thrombospondin-4 or COMP. The kits contain a detection agent for an autoantibody and can be used for diagnosing arthritis or a degenerative disease of the skeletal system. The active ingredient can be used for treating or preventing autoimmune-associated arthritis.

  • Patent number: 11542234
    Abstract: 6-[18F]Fluoro-2-alkoxynicotinoyl substituted Lys-C(O)-Glu derivatives were identified as efficient imaging probes for PSMA expressing tissues in comparison to other known PSMA specific ligands like [18F]DCFPyL, [68Ga]HBED-CC-PSMA, [18F]PSMA-1007 and [Al18F]HBED-CC-PSMA. Unexpectedly, the 6-[18F]fluoro-2-alkoxy and 6-[18F]fluoro-4-alkoxy substituted analogs showed significant differences in accumulation in PSMA expressing prostate tumor cells. Whereas the 2-alkoxy derivative showed cellular uptake values higher than [18F]DCFPyL, the cellular uptake of the corresponding 4-alkoxy substituted derivative was significantly lower. Furthermore, in vivo PET studies with 2-alkoxy-substituted probes demonstrated excellent visualization of PSMA positive ganglia with extremely high target to background ratio. In contrast, the 4-alkoxy substituted derivatives showed less favorable biodistribution with significantly lower uptake in PSMA positive tissues.

  • Publication number: 20210340489
    Abstract: A method of culturing Haematococcus species for manufacturing of astaxanthin comprising the steps of: providing a substrate, arranging the Haematococcus species on the surface of the substrate, exposing the Haematococcus species arranged on the substrate to high light intensities from the beginning of a culturing process and avoiding a two-step culturing process of the Haematococcus species with a first step which is an initial culturing taking place by exposure of the Haematococcus species to low light energy followed by a second step of subsequent culturing of the Haematococcus species by exposure of the Haematococcus species to higher light energy than applied in the first step to induce astaxanthin formation, and optionally—harvesting the cultured Haematococcus species and/or—isolating astaxanthin.
