Abstract: The invention relates to an electrically driven device (1) for the angular adjustment of a shaft relative to its drive (2), said device comprising an eccentric gearing that comprises at least one internally geared wheel and one spur gear that meshes with the internally geared wheel and can be driven by an electrically rotatable eccentric shaft. The considerable structural complexity and space requirement as also the noise level of prior art devices is reduced by the fact that the internally geared wheel is configured as a first and a second internally geared wheel (6, 9), and the spur gear is configured as a first and a second spur gear (16, 17) that have the same number of teeth and are rotatable in opposite directions, the internally geared wheels (6, 9) are connected to the drive (2) and the spur gears (16, 17) are connected to the camshaft and can be driven through a double eccentric shaft (20) comprising identical eccentrics (18, 19) arranged offset at 180° to each other.

Abstract: The present invention provides a method for exploring low molecular weight compounds which regulate positively or negatively the expression of human BMP-7 with reference to a reporter activity by using 5′ upstream region gene containing the human BMP-7 promoter and an animal cell introduced with the vector that has been connected to an appropriate reporter gene. The low molecular weight compounds and their derivatives obtained by the present method have morphogenetic activity or inhibiting activity for bone and cartilage through the expression of the human BMP-7 and are useful as preventive or therapeutic agents for cartilage and bone diseases. Furthermore, the low molecular weight compounds and their derivatives are useful as therapeutic agents for kidney diseases.
