摘要:
The invention relates to a method for determination of the frequency of regulatory T-cells in samples obtained from human blood and to methods for the preparation of compositions comprising predetermined amount of regulatory T-cells. The invention is based on the conception that a large fraction of regulatory T-cells present in human peripheral blood do not express detectable amounts of Foxp3, the master transcription factor used for identification of regulatory T-cells, as a result of cytokine deprivation outside of the tissue context.

The document proposes a diagnostic chewing gum for identifying the presence of pathogens detectable via the mouth, in particular residing in nasal, oropharyngeal, laryngeal, oesophageal, ocular and/or pulmonal tissue of a user, comprising a base material or particles (3) embedded and/or attached to said base material; an element (1, 5-7), like e.g. a releasable flavor molecule, attached to said base material and/or said particles, for the generation of a change in the chewing gum directly detectable by the user; wherein said pathogen is selected from the group consisting of virus, bacterium, protozoa, prion, fungus or a combination thereof; and wherein the element (1, 5-7) generates the change upon direct or indirect contact with a marker (4) which is released by said pathogens, or, in case of a virus or prion, by the cellular structure hosting it.
摘要:
The present invention discloses a therapeutic gas release system for oral administration comprising a therapeutic gas releasing compound A, and a therapeutic gas release triggering compound B, wherein compound A and B are separated from each other by an inner septum during storage of the system, wherein compound A and B are surrounded by an outer membrane, which is a gas-permeable and water- and solid-impermeable membrane, preferably a silicone membrane, and wherein therapeutic gas release from the system is activated before oral administration by breaking the inner septum. The therapeutic gas released from the system of the present invention is suitable for the treatment of (inflammatory) diseases of the gastrointestinal tract.
摘要:
The present invention relates to a monolithic multi-layered material having at least a first layer, from which anisotropic pores originate, and a second layer, in which the anisotropic pores continue. The present invention further relates to a monolithic medical material having at least a first layer, from which anisotropic pores originate, and a second layer, in which the anisotropic pores continue. The present invention further relates to a process for the production of a multi-layered material having anisotropic pores. It further relates to a multi-layered material which can be produced by the process according to the invention.
摘要:
A calculating unit for calculating a recording trajectory of a CT system has a receive interface, an optimizer and a control unit. The receive interface serves for receiving measurement and simulation data relative to the object to be recorded. The optimizer is configured to determine the recording trajectory based on known degrees of freedom of the CT system, based on the measurement and simulation data and based on a test task from a group having a plurality of test tasks. The control unit is configured to output data in correspondence with the recording trajectory for controlling the CT system.
摘要:
It is an object of the present invention to introduce carboxylic acid-functionalities suitable for coupling into the denatonium structure by means of simple synthesis, namely the synthesis of bitter principle derivatives based on the denatonium structure according to formula 1: For example, according to the invention, lidocaine derivatives may be reacted with carboxylated benzyl halogenides. The carboxylated denatonium derivatives of the present invention are especially applied in medicine, biology, medical engineering as well as cosmetics, the pharmaceutical, chemical, and foodstuff industry.
摘要:
The present invention relates to a gas delivery device comprising a gas releasing molecule and a gas permeable membrane. The invention also relates to the use of the gas delivery device for delivery of gas to an extracorporeal transplant, extracorporeal cells, a brain-dead transplant donor or foodstuff and in therapy. The invention further relates to the use of a gas permeable and liquid and solid impermeable membrane to separate a gas releasing molecule and its non-gaseous degradation products from an extracorporeal transplant, extracorporeal cells, a brain-dead transplant donor or foodstuff.
