The prevalence of PD-L1 expression in patients with advanced oesophageal cancer: the EXCEED observational study.

Aims: There are limited data on programmed death ligand 1 (PD-L1) expression in oesophageal cancer (OC) from multicentre studies conducted across China. We aimed to determine the prevalence of high PD-L1 expression in patients with advanced OC.

Methods: The EXCEED study was a multicentre, retrospective analysis of data from six tertiary hospitals that evaluated PD-L1 expression in adults with advanced OC or advanced head and neck squamous cell carcinoma.

White Fluorescent Carbon Dots for Specific Fe3+ Detection and Imaging Applications.

In recent years, carbon dots (CDs) with fluorescence imaging function have been widely used in biomedicine, electronic manufacturing and environmental monitoring. However, monochromatic fluorescence is often limited by the application environment and loses its effectiveness. Here, we carefully designed white fluorescent CDs (WF-CDs) by solvothermal method, which is used for fluorescence imaging applications under different environmental conditions.

Crystallization of CsPbBr Nanocrystals within a Melt-Quenched Glassy Coordination Polymer.

Lead halide perovskite nanocrystal materials such as CsPbX (X = Cl, Br, and I) have triggered an intense research upsurge due to their excellent scintillation performance. Herein, an crystallization strategy is developed to grow CsPbBr nanocrystals (NCs) within a low-melting-point (280 °C) coordination polymer (CP) glass. The viscosity of coordination glass is reduced through a low-temperature (e.

Spiny CoO@Hollow Carbon Spheres─Polyacrylonitrile/Carbon Black Fiber-Based Bifunctional Air Electrodes.

In the realm of zinc-air batteries, high bifunctional catalytic efficacy is intimately tied to the evaluation of catalysts. Consequently, the pursuit of proficient bifunctional catalysts that can efficiently catalyze both the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) remains a paramount objective in this research area. In this study, the spiny cobalt tetroxide (CoO) encapsulated hollow carbon spheres (HCSs) are constructed by anchoring CoO onto HCS via hydrothermal or annealing treatment.

Long Non-Coding RNA LINC01123 Facilitates Cholangiocarcinoma Aggravation by Targeting miR-641.

Background/aims: Cholangiocarcinoma (CCA) is a malignant and insidious tumor that is tricky to treat. Long non-coding RNA (LncRNA) LINC01123 is a biomolecule that influences cancer progression by regulating gene expression via influencing the regulatory function of microRNAs in gene expression. Therefore, this study investigated the connection between LINC01123 and CCA and explored the underlying mechanism.
