Radiomic Features of 18F‐FDG PET in Hodgkin Lymphoma Are Predictive of Outcomes
Contrast Media &Molecular Imaging, Volume 2021, Issue 1, 2021., 2021 Purpose. In the present study, we aimed to investigate whether the radiomic features of baseline 18F‐FDG PET can predict the prognosis of Hodgkin lymphoma (HL). Methods. A total 65 HL patients (training cohort: n = 49; validation cohort: n = 16) were retrospectively enrolled in the present study.

Journal of Oncology, Volume 2020, Issue 1, 2020., 2020 DEXD/H box helicase 60 (DDX60) is a new type of DEAD‐box RNA helicase, which is induced to express after virus infection. It might involve in antiviral immunity by promoting RIG‐I‐like receptor‐mediated signal transduction. In addition, previous studies had shown that the expression of DDX60 is related to cancer, but there was still a lack of relevant ...

基于氮化硼丙烯酸铅杂化填料的混合辐射场防护用柔性复合材料研究
He jishun-γ混合辐射场防护对于核能和核技术安全利用具有重要意义。将不同类型的辐射防护功能填料与基体材料共混是制备柔性n-γ辐射防护复合材料的常用方法，但受限于辐射防护功能元素分布不均、填料-基体界面相容性较差等问题，复合材料的辐射防护性能和力学性能有待提升，亟须兼具中子和γ射线防护功能的新型一体化填料。通过硼酸辅助球磨氮化硼和含巯基偶联剂接枝，制备了巯基化氮化硼纳米片；通过氧化铅和丙烯酸反应，合成了丙烯酸铅；以巯基化氮化硼纳米片和丙烯酸铅分别作为中子和γ射线防护前驱体，利用巯基-烯点击化学反应制备了氮化硼 ...
