摘要:
The present invention relates to a compound of general formula (I) below in which R1, R2 and R3 represent, independently of one another, a hydrogen atom or a C1-C6 alkyl group or a (C1-C6 alkyl)carbonyl group, R4, R5, R6 and R7 represent a hydrogen or a C1-C6 alkyl group, a C1-C6 alkoxy group or a (C1-C6 alkyl)carbonyloxy group, and n is an integer between 8 and 20, or its pharmaceutically acceptable addition salts, isomers, enantiomers and diastereoisomers, and also mixtures thereof. The invention also relates to a pharmaceutical composition comprising the compound and to the use thereof as a neurotrophic agent.
摘要:
Cell culture apparatus comprising at least two adjacent cell cultivation channels separated by a permeable or semipermeable membrane, wherein at least one channel, for the majority of its length, has a cross sectional area of no more than 1 mm 2 , said channel being provided with entrance and exit means to permit the passage of media therethrough, allows co-culture of separate cell types, e.g. human and microbial cells, without mingling, allowing monitoring of cell cultures and chemical exchanges between the respective cell cultures.
摘要:
According to a first aspect of the invention, a power inverter for converting source currents or voltages into alternating currents or voltages to be injected into a supply grid comprises a harmonics compensator configured to detect one or more harmonics of the fundamental frequency of the electrical supply grid and to control the alternating currents or voltages to be injected in such a way as to selectively modify the voltage of at least one of the one or more detected harmonics in accordance with one or more respective targets. A communication interface allows the power inverter to join a network of power inverters. The harmonics compensator is configured to share some or all of its operating parameters over the network and to adjust the one or more targets depending on instructions and/or operating parameters communicated to it via the network. A second aspect of the invention relates to a control unit for centrally controlling such power inverters.
