Nitrogen-doped porous carbon (NPC) materials were successfully synthesized via a Zn-containing metal-organic framework (Zn-MOF). The resulting NPC materials are characterized using various physicochemical techniques which indicated that the NPC materials obtained at different carbonization temperatures exhibited different properties. Pristine MOF morphology and pore size are retained after carbonization at particular temperatures (600 °C-NPC and 800 °C-NPC). NPC material shows an excellent surface area 1192 m/g, total pore volume 0.92 cm/g and displays a higher CO uptake 4.71 mmol/g at 273 k and 1 bar. Furthermore, NPC material displays good electrochemical sensing towards HO. Under optimized conditions, our sensor exhibited a wide linearity range between 100 µM and 10 mM with a detection limit of 27.5 µM.

Objectives: The study aimed to investigate the disease burden of nasopharyngeal carcinoma (NPC) in Asia.

Material And Methods: The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 data evaluated NPC metrics by sex, and age in Asia. Estimated annual percentage changes (EAPCs) were calculated to assess the trends of NPC burden.

Purpose: The objective of this study was to explore the performance of a predictive model for swallowing-induced breakthrough pain established using a redefined delineation method based on the common occurrence sites of radiation-induced oral mucositis (RIOM) in locally advanced nasopharyngeal carcinoma (NPC).

Methods And Materials: A total of 208 patients with locally advanced NPC were included in the study cohort, and the test cohort consisted of 88 patients. The oral mucosa structure was contoured using oral cavity contour (OCC), mucosal surface contour (MSC), and oral-pharyngeal mucosa (OPM) methods, and relevant dosimetric parameters were collected.

Introduction: The core objective of this study was to precisely locate metastatic lymph nodes, identify potential areas in nasopharyngeal carcinoma patients that may not require radiotherapy, and propose a hypothesis for reduced target volume radiotherapy on the basis of these findings. Ultimately, we reassessed the differences in dosimetry of organs at risk (OARs) between reduced target volume (reduced CTV2) radiotherapy and standard radiotherapy.

Methods And Materials: A total of 209 patients participated in the study.

High-Coordination and Nb-Bridging of Bimetallic Amorphous P-Nb-W-P Clusters in Carbon Nanospheres for High-Performance Sodium-Ion Hybrid Capacitors.

Adv Sci (Weinh)

January 2025

Key Laboratory of Jiangxi Province for Persistent Pollutants Control and Resources Recycle, Nanchang Hangkong University, Nanchang, Jiangxi, 330063, P. R. China.

Amorphous clusters are gaining prominence as prospective hosts for sodium-ion hybrid capacitors (SIHCs), but their efficacy is still affected by atomic coordination. Optimization of ion storage and charge transport can be achieved through high coordination and bimetallic configurations. Herein, high-coordination amorphous P-Nb-W-P (Nb/W-P) clusters are skillfully tailored by bridging Nb into the second shell of W in the W-P configuration, nested in situ in conductive and stable N, P co-doped carbon nanospheres (Nb/W-P@NPC).

Purpose To develop and evaluate a deep learning-based prognostic model for predicting survival in locoregionally- advanced nasopharyngeal carcinoma (LA-NPC) using serial MRI before and after induction chemotherapy (IC). Materials and Methods This multicenter retrospective study included 1039 LA-NPC patients (779 male, 260 female, mean age 44 [standard deviation: 11]) diagnosed between April 2009 and December 2015. A radiomics- clinical prognostic model (Model RC) was developed using pre-and post-IC MRI and other clinical factors using graph convolutional neural networks (GCN).
