Background Intestinal metaplasia (IM) is a premalignant lesion associated with gastric cancer. Both animal and clinical studies have revealed that bile acid reflux and subsequent chronic inflammation are key causal factors of IM. Previous studies indicated that SOX2, the key transcription factor in gastric differentiation, was downregulated during IM development while CDX2, the pivotal intestine-specific...
In order to improve the accuracy of recovered spectrum of Hadamard Transform Spectral Imager (HTSI), an algorithm of decomposing disorder encoding spectrum of HTSI using laser is proposed. The theory of Hadamard Transform (HT) is introduced. HTSI, which was developed in the Key Laboratory of Spectral Imaging Technique of Xi'an Institute of Optics and Precision Mechanics of Chinese Academy of Science...
