Abstract: A medical fluid pump, comprising a first, inner fluid system including a motor-driven suction/pressure unit and a first fluid pressure chamber which can be filled with fluid and emptied by the suction/pressure unit, and a second, outer fluid system including a second fluid pressure chamber which is coupled to the first pressure chamber in a pressure- and/or volume-dynamic manner via a movable separating wall and which is alternately coupled—via a valve means of the second fluid system—to a suction line and pressure line depending on the current working phase of the suction/pressure unit of the first fluid system is disclosed.

Abstract: The present invention relates to a nucleic acid molecule encoding a vacuolar invertase and its use for modifying the plant saccharose metabolism, in particular in the vacuole of the cell of a plant storage organ. The present invention also relates to a fragment of the nucleic acid molecule, a vector containing the nucleic acid molecule or a fragment thereof, as well as a host cell, in particular a plant cell that contains the nucleic acid molecule or a fragment thereof. The present invention also comprises a transgenic plant, methods for producing a transgenic plant, as well as methods for modifying the saccharose metabolism of a plant, in particular of a plant part.
