CT-based dosiomics and radiomics model predicts radiation-induced lymphopenia in nasopharyngeal carcinoma patients.

Purpose: This study aims to develop and validate a model predictive for the incidence of grade 4 radiation-induced lymphopenia (G4RIL), based on dosiomics features and radiomics features from the planning CT of nasopharyngeal carcinoma (NPC) treated by radiation therapy.

Methods: The dataset of 125 NPC patients treated with radiotherapy from August 2018 to March 2019 was randomly divided into two sets-an 85-sample training set and a 40-sample test set. Dosiomics features and radiomics features of the CT image within the skull bone and cervical vertebrae were extracted.

Optimized Microstructure and Improved Magnetic Properties of Pr-Dy-Al-Ga Diffused Sintered Nd-Fe-B Magnets.

The grain boundary diffusion process (GBDP) has become an important technique in improving the coercivity and thermal stability of Dy-free sintered Nd-Fe-B magnets. The influence of DyAlGa and (PrDy)AlGa alloys by the GBDP on sintered Nd-Fe-B magnets are investigated in this paper. After diffusing DyAlGa and (PrDy)AlGa alloys, the coercivity () of the magnets increased from 13.

[Effects of Huoxiang Zhengqi Oral Liquid on intestinal barrier function in rats with dampness obstructing spleen-stomach syndrome].

The aim of this paper was to investigate the effect of Huoxiang Zhengqi Oral Liquid on intestinal barrier functions in rats with dampness obstructing spleen-stomach syndrome and primarily explore the mechanism. The rat model of dampness obstructing spleen-stomach syndrome was established, and then the modeled rats were randomly divided into the model control group, Huoxiang Zhengqi Oral Liquid high and low dose groups, and natural recovery group according to gender and body weight, with 10 rats in each group. Another 10 rats were taken as blank control group.
