摘要:
A high-pressure device (100) is described, particularly a continental deep sea aquarium, having a shaft (10) extending into the earth's crust (11), and a pressure unit (20) disposed within the shaft (10) and having an internal pressure chamber that is pressure-resistant to exterior overpressure. Methods for the production and for the operation of such a high-pressure device (100) are also described.
摘要:
The invention relates to a method for creating cells that produce a pancreatic hormone, said method involving the cultivation and differentiation of stem cells that have been obtained from the differentiated exocrine glandular tissue of an organism. The invention also relates to the use of the cells that produce said pancreatic hormone.
摘要:
The invention relates to a carrier (10) for at least one sample chamber (11), especially for the cryopreservation of biological samples. Said carrier comprises a holding frame (20) which is used to position the sample chamber (11) and consists of a first frame part (30) and a second frame part (40) which can be detachably connected by means of connection elements (50) and respectively come into contact with each other at the lateral surfaces (31, 41) thereof, in the mounted state. Said sample chamber (11) can be fixed between the lateral surfaces (31, 41).
摘要:
The invention relates to a method for treating a biological cell (1) comprising a cytoskeleton (3) enveloped by a cell membrane (2). Said method comprises the following steps: the biological cell (1) and a tool (10) are mutually oriented such that the tool (10) comes into contact with the biological cell (1); the tool (10) and the biological cell (1) are displaced in relation to each other; and a gap is formed in the molecular composite of the cell membrane (2) of the biological cell (1). During the displacement of the tool (10), the cytoskeleton (3) of the biological cell (1) has a state of equilibrium. The invention also relates to a cell manipulator for carrying out the inventive method.
摘要:
The invention concerns supports (1200) for receiving a plurality of samples, in particular for preserving biological samples at cryotemperatures, said supports comprising a plurality of stacked support plates (11, 12, 13) and linked by an anchoring axis (20). The invention also concerns methods for preserving biological samples at cryotemperatures.
摘要:
The invention relates to methods for testing substances using multi-cellular, in vitro test systems, in particular systems that resemble organs and to devices and kits for carrying out said methods.
摘要:
The invention relates to a method for the production of a biological material composition having an animal, non-human origin, in particular in the form of animal or human food. Said method consists in forming an aggregation of stem cells from differentiated exocrine glandular tissue of an animal organism in order to form organoid bodies, and in preparing material compositions from the organoid bodies.
