Purpose: To demonstrate a new individualized 3D printed oral stent in radiotherapy of nasopharyngeal carcinoma (NPC) patients and carry out a comparative analysis combining with clinical case.
Material And Methods: Thirty NPC patients treated in our institution from September 2021 to October 2022 were prospectively enrolled. An individualized 3D printed oral stent was designed for each patient, and one set of computed tomography (CT) slices were obtained with /without wearing the oral stent, respectively.
Deacetylated Konjac Glucomannan (DKGM) and Konjac Oligo-glucomannan (KOGM) as two most widely used derivatives in food industry are structurally and physiologically distinct from Konjac glucomannan (KGM). However, the roles of their distinct structures and physicochemical properties in directing microbiota community and the following outcomes are not fully understood. This paper aims to build links between structural complexity of KGM and its derivatives and microbial metabolism.

The accuracy of the current wavelength meter using optical interferometry is limited by the numbers of fringe counted. To solve this problem, a novel laser wavelength meter based on the measurement of synthetic wavelength is proposed. The unknown wavelength is obtained by measuring the value of synthetic wavelength produced by the unknown and reference wavelengths, and half of this value corresponds to 2π variation of the phase difference between the interference signals of the unknown and reference wavelengths.
