The c-myc oncogene driven by immunoglobulin enhancers induces lymphoid malignancy in transgenic mice.

abstract：:The Borrmann effect-a dramatic increase in transparency to X-ray beams-is observed when X-rays satisfying Bragg's law diffract through a perfect crystal. The minimization of absorption seen in the Borrmann effect has been explained by noting that the electric field of the X-ray beam approaches zero amplitude at the cr...
