Also disclosed is the preparation of formula (I).
摘要:
The invention is relates to drugs on the basis of antibodies against non-cellular bone matrix proteins, especially BSP, for use in the prevention and treatment of bone metastases. According to the invention, the antibodies are induced in the patient by recombinantly expressing antigenic determinants of bone matrix proteins in Listeria and anchoring them on the surfaces thereof. The antigenic determinants are selected according to whether they are characteristic of antigens that are expressed by the tumor cells themselves.

Composition for treatment and prevention of human hair loss and/or hair greying, comprising an effective amount of thymic peptides of the family thymulin, thymosin alpha-1 and thymosin beta-4 and pharmaceutical excipient, diluent or carrier. Method and pharmaceutical composition for treatment and prevention of balding, hair loss, and alopecia.
摘要:
A bone graft or biocomposite for treating osseous defects and neogenesis of bone which is a composite of a biodegradable polymer and granules of beta-tricalciumphosphate, further comprising as active ingredient and embedded in the biodegradable polymer a physiologically effective amount of underglycosylated recombinant human BSP as a multi-dental clathrate with a basic organic compound which simulataneously is active as a plasticizer for the biodegradable polymer. The biocomposite is moldable and shapeable, hardens rapidly in situ when placed by surgery or prosthetic dentistry and which furthers osseous repair and the healing of damage or diseased tissues and lesions.
摘要:
The invention relates to a method of therapy against tumors and their metastases, which preferentially settle in bone tissue, comprising administering to a patient in need thereof an active ingredient which comprises at least one binding molecule that binds to human bone sialoprotein or a fragment thereof.
摘要:
Method for the quantitative determination of vitamins, amino acids, or other substances necessary for life, in a substance mixture, whereby in the culture container, the cavities of a microtitration plate, in each case a predetermined number of vital cells of a suitable microorganism are prepared in a permanent manner. For this purpose, the cells are shock frozen at −80° C. and then freeze dried in a freezing solution containing 200 to 500 mM trehalose/sucrose. The freezing solution is preferably the test medium. The culture containers are preferably the wells of a microtitration plate.
摘要:
Immunoassay for the determination of parathyroid hormone activity in a sample, and for the diagnosis, etiology and treatment of calcium metabolism disturbances, osteopathies and hyper- or hypoparathyroidisms. The parathyroid hormone activity is measured with the aid of an antibody which binds to an epitope in the region of the receptor binding structure 15 to 22 of the parathyroid hormone, and an antibody which recognizes whether the amino-terminal end 1 to 3 of the parathyroid hormone is intact. The assay permits the antagonistic characteristics of some parathyroid hormone fragments to be taken into account.
摘要:
The invention relates to a medicament against tumors and their metastases, which preferentially settle in bone tissue, comprising as active ingredient at least one binding molecule which binds to bone sialoprotein or a fragment thereof in serum or plasma.
摘要:
A method for quantitating vitamin D metabolites directly in blood plasma or serum, without the need for prior purification of the vitamin D metabolites, comprising a digestion of the serum proteins with a serine protease such as proteinase K and sequence of steps for inhibiting the proteinase K activity in the competitive binding analysis. The advantages of this method are its high accuracy over the whole range of physiologically relevant values and that it can be easily adapted for a fully automated analysis of serum and plasma samples.
