Abstract: The invention relates to a device and a method for the dissociation of tissue. In one embodiment, the device has at least one dissociation unit, for receiving a tissue sample, which is disposed at least partially in a pot-shaped cell strainer. In addition, the invention relates, in one embodiment, to a device and a method for the dissociation of tissue, the tissue being dissociated by a grinder having mutually movable rows of teeth which cut the tissue when moving past each other in the one direction and grind the tissue when moving past each other in the opposite direction.

Abstract: A manual-electronic pipetting device for pipetting a medium. The pipetting device includes a controller, a manually displaceable actuating element, at least one piston for aspirating and discharging the medium, a motor for driving the at least one piston in response to an actuation and/or displacement of the actuating element, at least one sensor for determining a displacement of the actuating element, and a data storage. The controller determines a pipetting protocol based on at least one sensor signal of the at least one sensor during a displacement of the actuating element, the controller further storing the pipetting protocol in the data storage, the pipetting protocol including data records indicative of a position and a speed of the at least one piston during the displacement of the actuating element.

Abstract: A manual-electronic pipetting device for pipetting a medium is provided. The pipetting device comprises a controller, a manually displaceable actuating element, at least one piston for aspirating and discharging the medium, a motor for driving the at least one piston in response to an actuation and/or displacement of the actuating element, at least one sensor for determining a displacement of the actuating element, and a data storage. The controller is configured to determine a pipetting protocol based on at least one sensor signal of the at least one sensor during a displacement of the actuating element, wherein the controller is further configured to store the pipetting protocol in the data storage, the pipetting protocol comprising data records indicative of a position and a speed of the at least one piston during the displacement of the actuating element.

Abstract: The invention relates to a crimped connection (1) between the end (2) of an electrical conductor (3) which is made of high-grade steel and a connector (4) with the end (2) of the electrical conductor (3) being disposed in the compressed connector (4). According to the invention, the end (5) of an electrical conductor (6) made of copper is additionally placed in the connector (4).

Abstract: The present invention relates to the homodimerization of the amyloid precursor protein (APP) and the relevance of this process for the presence of enhanced amounts of the amyloid ?-peptide (A?) in vivo. The present invention provides novel compounds useful for the diagnosis/prevention/treatment of diseases like Alzheimer's disease. Also provided are vectors, host cells and antibodies. The invention further relates to diagnostic and therapeutic methods useful for diagnosing and treating Alzheimer's disease.

Abstract: Balhimycin, where appropriate in combination with one or more of its derivatives, is suitable for promoting production in monogastric or polygastric animals.
