20120225452 | NUCLEIC ACID MOLECULE FOR ENCODING XYLOSE ISOMERASE AND XYLOSE ISOMERASE ENCODED BY THE NUCLEIC ACID MOLECULE - A novel xylose isomerase nucleotide sequence obtained from a bovine rumen fluid metagenomic library and also provides the amino acid sequence encoded by the nucleotide sequence, and a vector and a transformant containing the nucleotide sequence. When the xylose isomerase is expressed, a host cell is endowed with the capability of converting xylose into xylulose, and the xylulose is further metabolized by the host cell. Therefore, the host cell can take the xylose as a carbon source for growth. The xylose isomerase from a new source is expressed with high activity in | 09-06-2012 |
20120179025 | CT AND MRI SYNCHRONOUS DETECTION POSITIONING NEEDLE - Disclosed is a CT and MRI synchronous detection positioning needle. The needle comprises a silicone tube which is internally provided with a guide needle; the two sides of the guide needle are provided with hollow cavities; each hollow cavity is internally provided with membranes dividing the hollow cavity into a plurality of small chambers which are filled with liquid, wherein a CT contrast agent is filled in a plurality of small chambers at one side of the guide needle, and an MRI contrast agent is filled in a plurality of small chambers at the other side of the guide needle. In the invention, specially designed silicone positioning needles are implanted in vivo, and synchronous comparison of different image data and pathological data is implemented by means of multi-plane reconstruction technology, so the CT and MRI synchronous detection positioning needle can be widely applied to experimental study on tumors. | 07-12-2012 |
