摘要:
The present invention provides agents for inhibiting the proliferation of cancer cells, wherein the agent inhibits the biological activity of hCAP18/LL-37. In a preferred embodiment, the agent alters the transcription, translation and/or binding properties of hCAP18/LL-37. Preferably, the agent is selected from the group consisting of short interfering RNA (siRNA) molecules, antisense oligonucleotides and compounds with binding affinity for hCAP18/LL-37. The invention further provides methods for inhibiting the proliferation of cancer cells in a patient, as well as methods and kits for diagnosing cancer.

The present invention relates to a new, particularly economical process for preparing particulate water-soluble cellulose derivatives. The process involves forming a feed composition of swollen and/or dissolved cellulose derivative, and water. The feed composition is contacted with a superheated gas mixture, in a sieve-free high rotational speed gas jet impact mill, and the cellulose derivative of the feed composition is converted into a solid state form of finely particulate particles. The superheated gas mixture, with which the feed composition is contacted, is selected from: (i) a superheated gaseous mixture of steam and an inert gas; and (ii) a superheated gas mixture of steam and air. The superheated gas mixture has a steam content of 40 wt. % to 99 wt. %, based on the total weight of the superheated gas mixture.

The invention relates to an open-loop control process for the motional guidance of conveyed material (32) in a conveying device (30) and to a corresponding conveying device (30). The conveying device (30) has a movable means (36) for realizing the conveyance and a first motion detector (42) for measuring a first actual position value (x1act) for the movable means (36) and a second motion detector (40) for measuring a second actual position value (x2act) for the conveyed material (32). The control is herein realized with a position control having a position control clock (Tpc) and with a speed control (GR) having a relatively faster speed control clock (Tsc), in which, in the position control clock (Tpc), desired position values (xcmd) are preset as the command variable and, in the speed control clock (Tsc), registered first actual position values (x1act) are fed back to the position control, in which the position control is provided, at least in part, in an open-loop control part (NC) and the speed control (GR) is provided in a drive part (A), and in which a control variable (R) is fed back into the position control, which control variable is dependent on second actual position values (x2act) registered in the position control clock (Tpc). A high accuracy and dynamic can thereby be obtained.
摘要:
A transmission gear wheel has at least two gear wheel elements which are provided with teeth on their circumference and which, coaxially and non-displaceably with respect to one another in the circumferential direction. Mutually offset teeth connect the elements with one another such that, for the engagement of a meshing gear wheel, the existing tooth flank play is reduced or discontinued. At least the teeth of one gear wheel element are constructed such with respect to their elasticity that, during the engagement of meshing gear wheel, at least starting at a defined transmitted torque, the offset in the circumferential direction of the tooth transmitting this torque is at least partially discontinued with respect to the tooth of the other gear wheel element by means of a deformation.

The present invention provides thermoplastically workable and completely biodegradable moulding compositions, a process for the preparation thereof and the use thereof as biodegradable materials for the production of, for example, injection-moulded parts, films, fibres or coatings.
摘要:
Reflective type radiation sensor mounted on one side of the path of sheet film moving from one apparatus to another apparatus cooperates with a reflector mounted on the opposite side of the film path, preferably on a shaft of roller transport for moving the film sheet, to detect film sheet position, the radiation travel being other than at right angles to the film path.
摘要:
Polyalkylene terephthalates which contain a fluorinated polyolefin in addition to a polymer having a glass transition temperature of less than -30.degree. C., are very tough, exhibit good stability to thermal shaping and hardness, and have a high modulus of elasticity and improved stress/strain behavior.
摘要:
In a continuous process for the removal of H.sub.2 S from a gaseous mixture involving: (a) simultaneous absorption and oxidation of H.sub.2 S to form elemental sulfur; (b) regeneration of the oxidizing agent, e.g., vanadate, by treating the used scrubbing liquid with air; and (c) recycling the regenerated scrubbing liquid to the scrubbing step, to avoid the formation of sulfates and thiosulfates, the dissolved oxygen is substantially prevented from appearing in the scrubbing solution before reuse.
摘要:
A motor vehicle door lock comprises a ratchet locking mechanism, behind the preferably bolt-shaped catch of which there can engage the flanks of two locking teeth which are arranged one behind the other and which are arranged on a pivotable locking lever which is pressed into the locking position by spring pressure and which, upon a movement of the catch relative to the lever during the locking of the door, can be pivoted by the catch against the spring pressure. For the opening of the lock there engages in the locking lever (9) or is secured thereto, a driving member (28), by means of which the locking lever can be removed from the catch (2) to such an extent that the respective abutting tooth edge becomes disengaged.
摘要:
Described is a building material composition prepared from or having added thereto a particulate material selected from particulate polysaccharides or particulate polysaccharide derivatives. The particulate material of the building material composition is prepared by a method comprising: (a) forming a feed composition comprising a member selected from the group consisting of polysaccharides and polysaccharide derivatives, and 35 wt. % to 99 wt. % of water, based on the total weight of the feed composition, wherein said member is at least one of swelled and dissolved in the feed composition; (b) contacting, in a mill, the feed composition with a gas stream, thereby converting simultaneously the water of said feed composition into water vapor, and said member of said feed composition into a solid state form of finely particulate material; (c) separating the particulate material from the gas stream; and (d) optionally drying the particulate material. Examples of building material compositions according to the present invention include tile adhesives and joint fillers.
