Prognostic value of pretreatment systemic immune-inflammation index in Chinese esophageal squamous cell carcinoma patients receiving radical radiotherapy: A meta-analysis.

Background: The association between pretreatment systemic immune-inflammation index (SII) and long-term survival among Chinese esophageal squamous cell carcinoma (ESCC) patients who received radical radiotherapy remains unclear. The aim of this study was to identify the prognostic role of pretreatment SII in Chinese ESCC patients receiving radical radiotherapy based on current evidence.

Methods: The PubMed, EMBASE, Web of Science and CNKI databases were searched up to March 18, 2023.

A facile non-solvent induced phase separation process for preparation of highly porous polybenzimidazole separator for lithium metal battery application.

The drawbacks of low porosity, inferior electrolyte wettability, low thermal dimensional stability and permissive lithium dendrite growth of the conventional microporous polyolefin-based separators hinder their widely application in the high power density and safe Lithium ion batteries. Herein, highly porous polybenzimidazole-based separator is prepared by a facile non-solvent induced phase separation process (NIPS) using water, ethanol, chloroform and ethyl acetate as the coagulation bath solvent, respectively. It was found that the ethanol is suitable to fabricate uniform morphology macroporous separator with the porosity of 92%, electrolyte uptake of 594 wt.

A seven-long noncoding RNA signature predicts relapse in patients with early-stage lung adenocarcinoma.

Background: Long noncoding RNA (lncRNA) has been increasingly reported to play crucial roles in cancer development. In this study, we aim to develop a lncRNA-based signature to predict the relapse of early-stage (stage I-II) lung adenocarcinoma (LUAD).

Methods: With a lncRNA-mining strategy, lncRNA expression profiles of three LUAD cohorts were obtained from the Gene Expression Omnibus database.

A gel single ion conducting polymer electrolyte enables durable and safe lithium ion batteries graft polymerization.

Concentration polarization issues and lithium dendrite formation, which associate inherently with the commercial dual-ion electrolytes, restrict the performance of lithium ion batteries. Single ion conducting polymer electrolytes (SIPEs) with high lithium ion transference numbers ( ≈ 1) are being intensively studied to circumvent these issues. Herein, poly(ethylene--vinyl alcohol) (EVOH) is chosen as the backbone and then grafted with lithium 3-chloropropanesulfonyl(trifluoromethanesulfonyl)imide (LiCPSI) Williamson's reaction, resulting in a side-chain-grafted single ion polymer conductor (EVOH--LiCPSI).

High rate lithium-sulfur battery enabled by sandwiched single ion conducting polymer electrolyte.

Lithium-sulfur batteries are highly promising for electric energy storage with high energy density, abundant resources and low cost. However, the battery technologies have often suffered from a short cycle life and poor rate stability arising from the well-known "polysulfide shuttle" effect. Here, we report a novel cell design by sandwiching a sp(3) boron based single ion conducting polymer electrolyte film between two carbon films to fabricate a composite separator for lithium-sulfur batteries.

A hyperbranched conjugated Schiff base polymer network: a potential negative electrode for flexible thin film batteries.

A hyperbranched conjugated Schiff base polymer network was synthesized by condensation between 4,4',4''-nitrilotribenzaldehyde and p-phenylenediamine. The material exhibits excellent rate capability and long cycle life for lithium storage. Coupled with lower electrode potential (0.

Star-shaped donor-pi-acceptor conjugated oligomers with 1,3,5-triazine cores: convergent synthesis and multifunctional properties.

Monodispersed oligomers have been widely developed and used in different optoelectronic areas due to their well-defined molecular structures, high purity, and solution processability. Star-shaped oligomers are especially interesting for OLED application because of their antiaggregation abilities and stable electroluminescence. In addition, star-shaped donor-pi-acceptor conjugated molecules are known to afford good nonlinear optical and two-photon absorption properties due to the intramolecular charge transfer and cooperative enhancement effects.

New optoelectronic materials based on bitriazines: synthesis and properties.

A series of bitriazine derivatives were synthesized for the first time by the self-coupling reactions of the monocholoro-triazines in the presence of nickel catalyst. Such bitriazines show excellent optoelectronic properties.
