摘要:
Transgenic nonhuman mammals, such as transgenic mice, which lack erythropoietin expression, in which the erythropoietin receptor is deleted, which carry a heterologous erythropoietin receptor (e.g., a chimeric receptor); constructs useful for producing such transgenic nonhuman mammals, embryonic stem cells containing the constructs, a method of producing the transgenic nonhuman mammals and a method of identifying erythropoietin mimics or mimetics.
摘要:
Disclosed are compounds of formula (I) and pharmaceutically acceptable salts thereof. The compounds of formula (I) inhibit tyrosine kinase activity of JAK3, thereby making them useful for the treatment of inflammatory and autoimmune diseases.
摘要:
The present invention provides a system, method and terminal for communication between WAPI terminals, and the method includes: a calling terminal that has a WAPI function sending a WAPI link establishment request to a called terminal that has a WAPI function, and establishing a WAPI link with the called terminal, the calling terminal communicating with the called terminal directly through the established WAPI link. Using the technical scheme according to the present invention, the direct communication between the WAPI terminals can be realized, and the technical scheme is easy to implement and can reduce the communication costs, and would not be influenced by the coverage ratio of radio signal of a radio operator, a real-time communication will be realized as long as it is within the application scope of the WAPI.

摘要:
From tungsten or molybdenum powders, a tungsten or molybdenum compact is pressurized and molded into the same dimensions as or slightly larger than the end product and sintered into tungsten or molybdenum skeleton. After copper infiltration, chemical copper etching is applied to remove excess surface copper. A machining allowance with an absolute value >0-≦0.1 mm may be applied for the machining of uneven surfaces resulting from the chemical process of copper removal.

A dynamic shift register includes a first stage (21) and a second stage (22). The first stage includes a logical inputting port (201), a first retaining circuit (231), and a first transmitting gate (211). The first transmitting gate includes an input connected to the logical inputting port, and an output connected to the first retaining circuit. The second stage includes a logical outputting port (205), a second retaining circuit (232), and a second transmitting gate (212). The second transmitting gate includes an input connected to the output of the first transmitting gate, and an output connected to the logical outputting port and the second retaining circuit. In a cycle, after the clock signal and the complementary clock signal are stopped, the dynamic shift register can stably retain the logical signal.
摘要:
Compositions and methods are provided for killing and controlling pests by using cocktails of plant alkaloids. In one embodiment, the pesticidal composition comprises: anabasine; and one or more plant alkaloids selected from the group consisting of toosendanin, azadirachtin, tomatine, nicotine, matrine, oxymatrine, sophocarpine, N-oxysophocarpine, cytisine, and aloperine. The pesticide can be used to protect crop plants, wood structures and animals from damages by harmful pests, overcome resistance of pests to current commercial pesticides, and reduce contamination to the environment.
摘要:
A battery cover structure includes a removable cover and a main body. The cover defines two cutouts at an end thereof. The main body includes a first housing and a second housing. The first housing defines a through hole. An elastic arm extending from the first housing and is received in the through hole. Two latching blocks respectively extend from two sides of the arm and are respectively engaged in the cutouts of the cover. The arm includes a distal portion. The second housing is integrally formed with the first housing. The second housing includes a flexible operating portion above the distal portion of the arm. When the operating portion is pressed down, the at latching blocks are detached from the cutouts so as to remove the cover.
摘要:
A cover mechanism is for an electronic device, and the cover mechanism includes a base member and a cover member. The base member defines a hole and a receiving groove. The cover member is received in the receiving groove. The cover member includes a connecting portion to allow the cover member to be elastically bent to cover the hole.
