Abstract: The invention relates to an efficient process and device for the decontamination of waters polluted with heavy metals, semimetals and/or radionuclides by cation exchange and electrochemical deposition of the anions.

Abstract: The present invention relates to metal-containing ribonucleotide polypeptides (RNP) and processes for their production, their use and medicaments containing ribonucleotide polypeptides or their molecular-biological equivalent structures and/or parts and/or derivatives.

Abstract: The invention concerns a peptide having the biological activity of an inhibitor of amyloid formation and its diagnostic and medical use.

Abstract: The present invention relates to a method and an apparatus for separating substances from or in biological materials.

Abstract: Calcitonins and calcitonin derivatives such as are employed for therapy for, for example, osteoporosis. Paget's disease or hypercalcemia. The calcitonins and calcitonin derivatives are distinguished by a bridging of the amino acids present in the positions 17 and 21. In this case, by means of a suitable choice of the amino acids present in these positions an 18- or 19-membered ring is produced. This ring leads to an increased conformational stability and to an increased activity of the modified calcitonin. A particularly suitable hCt (human Ct) analog is the cyclo17,21-[Asp17, Orn21]-hCt according to the invention having a 19-membered ring structure between the lactam-bridged Asp17 and Orn21.

Abstract: The invention relates to a method and a device for the isolation and purification of nucleic acids. According to the invention, after decomposition of a sample the nucleic acids present in said sample are isolated and purified.

Abstract: The patent relates to a method for spectroscopic and spectrofluorimetric determination of the interaction between materials. The determination takes place using apparatus consisting of several basins.

Abstract: Certain peptide molecules can be used as the basic structures (template molecules) for inhibiting and analysing amyloid formation and cytotoxicity in amyloid illnesses. These peptides have an effect on the molecules which are responsible for the amyloid illnesses (for their part amyloid-forming peptides and proteins). The peptides are thus either inhibitors themselves or agonists of amyloid formation and cytotoxicity or can serve as a template for identifying and producing further inhibitors and agonists and can be used as molecular tools during analysis.

Abstract: Superpotent calcitonin analogs have greatly increased hypocalcemic action in vivo. These calcitonins and calcitonin derivatives are employed for the therapy of, for example, osteoporosis, Paget's disease or hypercalcemia. The calcitonins and calcitonin derivatives are distinguished by a bridging of the amino acids present in the positions 17 and 21. By means of suitable choice of the amino acids present in these positions an 18-membered or 19-membered ring is produced. This ring leads to an increased conformational stability and to an increased activity of the modified calcitonin. A particularly suitable hCt (human calcitonin analog) is a cyclo17,21-[Asp17, Orn21]-hCt having a 19-membered ring structure between the lactam-bridged Asp17 and Orn21.

Abstract: The present invention provides a stabilized, NAD(P)H-dependent, soluble nitrate reductase of the assimilatory type, characterized by a molecular weight of about 90,000 D in the case of electrophoresis in the presence of sodium dodecyl sulphate and a residual activity after 3 weeks at 35.degree. C. of more than 60%, obtainable by preparing a suspension of the comminuted starting material in tris/tartaric acid buffer (pH 7-8.5), adding soluble polyethyleneimine thereto in such an amount that 10 to 20% of the nitrate reductase activity passes into the precipitation obtained, separating off the precipitate and working up the supernatant according to conventional biochemical methods of fractionation in the above-mentioned digestion buffer, dialyzing the enzyme solution obtained and lyophilizing in a zwitterionic buffer.

Abstract: The present invention provides a process for obtaining cholesterol esterase from micro-organisms of the genus Pseudomonas, wherein Pseudomonas sp. DSM 1280 or DSM 1281 is cultured in an appropriate culture medium in the presence of an inducer and the enzyme is obtained from the culture medium and/or from the cells.

Abstract: The present invention provides a process for obtaining cholesterol esterase from micro-organisms, wherein a micro-organism capable of cholesterol esterase formation is cultured in an appropriate nutrient medium in the presence of lecithin as inducer and the enzyme is obtained from the culture medium and/or from the cells.
