CONSTRUCTION AND IDENTIFICATION OF THE RECOMBINANT OF THE AAV VECTOR AND HUMAN INTERFERON-GAMMA

To construct and identify further a recombinant of Adeno-associated virus and interferon-gamma for gene therapy, the full-length IFN-\%γ\%cDNA containing signal peptide was amplified by PCR, and then cloned into the pUC18. After screening, the fragment from the positive clone was then subcloned into pwp...  (本文共3页) 阅读全文>>

Attenuation coefficients of gamma and X-rays passing through six materials

The aim of this study was to determine the attenuation of gamma and X-rays with different energies caused by passage through different materials. To this end,different materials with a range of atomic numbers were chosen to measure gamma and X-ray attenuation coefficients and to explore the mechanisms of interaction of gamma and X-rays with matter of various kinds. It is shown that the attenuation coefficients first ...  (本文共6页) 阅读全文>>

An investigation of gamma ray mass attenuation from 80.1 to 834.86 keV for fabric coating pastes used in textile sector

In the present study, we investigate several textile coating pastes used in the market based on their radiation protection capability for gamma rays. The gamma ray mass absorption coefficients of some coating pastes doped with antimony, boron and silver elements have been investigated. It has been determined that the gamma ray mass attenuation coefficient decreases rapidly as the energ...  (本文共8页) 阅读全文>>
