  • Publication number: 20120059152
    Abstract: As a result of dedicated research, the present inventors have successfully invented a collagen gene construct which can be easily purified and maintains a triple helix structure equivalent to that of naturally-occurring collagen while having a low molecular weight. Specifically, one-step purification by affinity purification is enabled because CR-D (a signal peptide) has a carbohydrate recognition domain. By substituting a portion of a human collagen structural gene of the present invention with the collagen-like structural gene portion of MBL, a low-molecular-weight collagen which maintains a triple helix structure and is thermally stable can be obtained with high purity and in large quantities.

  • Patent number: 8117021
    Abstract: A method, apparatus, and computer instructions for testing software programs running on a data processing system. Text is translated from the source language to the target language to form translated text in response to a user input, containing the text in a source language. The text is entered through a computer interface in the data processing system.

  • Patent number: 8054275
    Abstract: In one embodiment of the present application, a memory stores a lookup table storing, in accordance with a combination of a value of a video signal of a current frame and a value of a video signal of a previous frame, each of correction values, the correction values in each of which a temporal change of a video signal is enhanced. A correcting circuit carries out, with respect to a correction value selected from the lookup table, a predetermined correcting operation in accordance with a polarity of a voltage to be applied to each of data signal lines S1 through Sm, with the use of a correction coefficient which is set based on properties of liquid crystal. Thus found is a corrected video signal in accordance with a positive or negative polarity. This makes it possible to find, with less memory capacity, an optimum corrected video signal in accordance with a polarity of a voltage to be applied to a data signal line.
