Prognostic Value of c-MYC Expression in Patients with Peripheral Neuroblastic Tumors.

Objective: Neuroblastic tumors are the most common solid tumors in children. The aim of this study was to explore the prognostic value of immunostaining for cellular-myelocytomatosis viral oncogene (c-MYC) expression in patients with peripheral neuroblastic tumors (NTs).

Methods: A retrospective study was conducted to compare the expression of c-MYC detected by immunohistochemistry and v-myc avian myelocytomatosis viral oncogene neuroblastoma derived homolog () by fluorescence in situ hybridization among 177 cases of NTs and determine the associations of c-MYC and with the clinical stages, morphological types, and survival rates of NTs.

Digital mapping of zinc in urban topsoil using multisource geospatial data and random forest.

This study aimed to map the spatial patterns of Zn in urban topsoil by using multisource geospatial data and machine learning method. Geological map, digital elevation models, and Landsat images were used to extract data related to geology, relief, and land use types and a vegetation index. Urban functional types were derived from the fusion of Systeme Probatoire d'Observation de la Terre 5 images, points of interest, and real-time Tencent user data.

Tumor microenvironment responsive supramolecular glyco-nanovesicles based on diselenium-bridged pillar[5]arene dimer for targeted chemotherapy.

Supramolecular glyco-nanovesicles (SeSe-(P5)2⊃Man-NH3+) based on the host-guest complex of a diselenium-bridged pillar[5]arene dimer and a mannose derivative have been successfully developed for the first time, which possessed tumor microenvironment-responsiveness and specific targetability due to their diselenium bonds and mannose units, respectively.

Effects of temperature fluctuations on a SQUID-based superconducting gravimeter.

A superconducting gravimeter based on the superconducting quantum interference device system is under development. As the main source of low-frequency noise, temperature fluctuations affect the resolution of superconducting gravimeters. In this study, a set of experimental devices was built to investigate the primary coupling processes of temperature fluctuations in superconducting gravimeters.
