摘要:
In the process of generating ZO-1 gene knockout mice, the present inventors developed gene targeting vectors that allow homologous recombination to occur at a high probability (90% or more). In addition, the present inventors used the targeting vectors for studying optimal electroporation conditions in epithelial cells, and as a result, successfully determined optimal electroporation conditions that would enable efficient gene targeting in the EpH4 mouse epithelial cell line. Use of the vectors of the present invention enables easy introduction of exogenous genes into the ZO-1 allele of ES cells. Moreover, since effects on the genomic structure need not be considered, the methods of the present invention are expected to solve problems encountered in the conventional methods for generating transgenic mice and stable transformants.

An audio communication system includes a first analog/digital convertor, a second analog/digital convertor, and an echo canceller. The first analog/digital convertor converts an audio signal, which is input from a microphone, to a data signal. The second analog/digital convertor that converts an audio signal, which is input from an auxiliary input terminal, to a data signal. When an audio signal transmitted from the outside is received and output from a speaker, the echo canceller prevents an output of the speaker from being input through the microphone and echoed back to a recipient or remote device. An operating frequency of the echo canceller is relatively lower than a sampling frequency of the second analog/digital convertor.

A printing apparatus includes a printing unit for printing visual information on a non-recording surface of a rotatably driven recording medium by discharging ink droplets. A control unit controls movement of the printing unit in a radial direction of the recording medium, and discharge timing of the ink droplets. The printing unit prints the visual information by multi-path printing by printing on a same radius position of the non-recording surface by discharging ink from different ink discharge nozzles. The control unit controls the printing unit so as to print with a first printing pattern having a first number of paths and a second printing pattern having a second number of paths. The first printing pattern is used on other locations of the non-recording surface and the second printing pattern is used when printing on an innermost periphery region of the non-recording surface.

A bacterial toxin protein such as a Shiga toxin protein is efficiently produced using plant cells. The plant cells are transformed using a DNA construct containing DNA encoding a hybrid protein in which the bacterial toxin proteins such as the Shiga toxin proteins are tandemly linked through a peptide having the following characteristics (A) and (B) to produce the bacterial toxin protein in the plant cells: (A) a number of amino acids is 12 to 30; and (B) a content of proline is 20 to 35%.

A technology for producing a pig edema disease vaccine at low cost and at high efficiency is developed. Specifically, a gene of a pig edema disease toxin protein (Stx2e protein) is efficiently expressed in plant cells to produce a plant vaccine for pig edema disease at low cost. An Stx2e protein including a secretory signal peptide derived from a plant added at an amino terminus is expressed in cells of a plant such as Lactuca sativa using the 5′-untranslated region of an alcohol dehydrogenase gene (ADH5′UTR) derived from a plant.
摘要:
A recording medium drive apparatus is disclosed. The recording medium drive apparatus includes a holding mechanism, a data recording means, and a printing means. The holding mechanism holds a recording medium having a print target surface targeted for printing and an optical recording surface for data. The data recording means is capable of recording the data on the optical recording surface held by the holding mechanism. The printing means is capable of performing printing on the print target surface of the recording medium and applying a correction fluid on the print target surface.

A three-dimensional modeling apparatus includes a stage, a supply mechanism, a head, a movement mechanism, and a lifting and lowering mechanism. On the stage, a powder material is accumulated. The supply mechanism supplies the powder material on the stage for each predetermined layer thickness. The head ejects a liquid for forming a three-dimensional object to the powder material on the stage. The liquid is capable of binding the powder material. The movement mechanism moves the stage so that the liquid is supplied from the head to the powder material by the predetermined layer thickness. The lifting and lowering mechanism lowers the stage for each predetermined layer thickness.

Disclosed is a liquid ejecting head includes a head main body having nozzles facing a spray surface of a rotating member rotationally driven, and ejecting liquid from the nozzles, and a mist capturing unit capturing mist of the liquid ejected from the nozzles. In the liquid ejecting head, the mist capturing unit is formed such that a passage, through which air flows in a predetermined direction over the spray surface while the rotating member is driven to rotate, is formed narrower than a distance between the nozzles and the spray surface.
