摘要:
The invention concerns an optically controllable microelectrode arrangement for stimulating cells (27), in particular a retina implant. This arrangement comprises a surface (28) abutting a tissue, for example a retina (12), containing the cells (27). The surface (28) is provided with electrodes (35a) for stimulating tissue cells (27). The electrodes (35a) are controlled by light (21, 22) impinging on the tissue such that the electrode (35a) exerts an electrical stimulus (41) on the cell (27). The surface (d) of the electrode (35a) used for contact with a cell (27) is substantially smaller than the surface (B) of the cell (27) used for contact with the electrode (35a).
摘要:
The invention relates to a method for detecting resistant fungi cells in clinical material. According to said method, fungi-specific nucleic acids are initially extracted from the clinical material and subsequently hybridized with fungi-specific hybridization probes which are targeted against nucleic acid segments of azole derivative-resistant fungi cells.
摘要:
The present invention relates to the use of at least one antibody which binds to the SUSD2 antigen, or to functional fragments of the antibody, in combination with at least one of the following: an antibody which binds to CD140b, an antibody which binds to CD56, and/or an antibody which binds to TNAP, or functional fragments thereof, for isolation of mesenchymal stem cells, especially those having particularly chondrocytic and osteogenic differentiation potential. The invention further relates to processes for isolating such stem cells using these antibodies.

The invention relates to a method for setting a frequency-dependent amplification of a hearing aid (30), wherein the amplification is automatically adjusted according to the frequency. The method comprises the following steps: selecting a sound having specific frequency (f1...fn); outputting the sound by means of a transmission element (42), in particular a speaker; detecting an analysis noise, which comprises an ambient noise (32), if present, and a reflection (48) of an output noise (46), which is output by means of the transmission element (42), by means of a sensor element (34), in particular a microphone; extracting a rejection of the fed-in sound from the detected analysis noise; determining a reflection component (S1...Sn) for the specific frequency (f1...fn) of the fed-in sound; and adapting the amplification in a frequency-specific manner on the basis of the reflection component determined in such a way.
摘要:
The present invention relates to the use of a peptide selected from the group comprising laminin-1, collagen-1, collagen-3, collagen-4, tenascin, thrombospondin-1, osteopontin, fibronectin, vitronectin, or fragments or mixtures of these, for isolating and/or identifying mesenchymal stem cells (MSC), in particular of peptide fragments of these peptides. The invention furthermore relates to the use of these peptides/peptide fragments in the treatment of wounds, injuries and/or degenerated tissue.
摘要:
The invention relates to a method for the visual examination of biological material ex vivo and to a device for the spatial orientation of biological material which device can be used in said method.
