Although WO exhibits both electrochromic and photoelectrochemical (PEC) properties, there is no research conducted to investigate the correlation between them. The study herein reports the electrochromic enhancement of PEC activity on WO. The electrochromic WO (e-WO) exhibits a significantly enhanced activity for PEC water oxidation compared to raw WO (r-WO), with a limiting photocurrent density three times that of r-WO.

Taking advantage of the IR-thermal effect to facilitate sluggish electrocatalytic reactions emerges as a promising way to utilize the IR band of the solar spectrum. In this work, nickel foam (NF) supported NiCoO nanoneedles (NF/NiCoO NNs) were prepared to promote the oxygen evolution reaction (OER) via the IR-thermal effect, with the NF/NiCoO NNs acting as both the IR absorbing antennae and the OER active anode.

Herein, a novel type of coupled heterostructure was designed by simple electrodeposition followed by a sulfurization treatment. This hierarchical structure was composed of nickel sulfides (NiS, NiS , denoted as NiS ) and oxygen-deficient tungsten oxide (WO ), which was directly grown on nickel foam (NF) as self-supporting electrodes (NiS -WO /NF) for HER over a wide pH range.

Methods: A generalized linear model (GLM) to predict pCR in LARC patients previously trained in Europe and validated with an external inter-continental cohort (59 patients), was first examined with further 88 intercontinental patient datasets to assess its reproducibility; then new radiomics and clinical features, and validation methods were investigated to build a new model for enhancing the pCR prediction for patients admitted to our department. The patients were divided into training group (75%) and validation group (25%) according to their demographic.
Background: This retrospective study was conducted to: (1) provide more modern data on real-life local management of metastatic rectal cancer; (2) compare therapeutic strategies; and (3) identify prognostic factors of local failure, overall survival and progression-free survival.
Methods: Data about efficacy and acute toxicity were collected. Patients were diagnosed with metastatic rectal cancer between 2004 and 2015, and were treated at least with radiotherapy.
Heart diseases and cardiovascular events are well-known side effects in left-sided breast irradiation. Deep inspiration breath hold (BH) combined with fast delivery techniques such as volumetric modulated arc therapy (VMAT) or tangential field-in-field (TFiF) can serve as a valuable solution to reduce the dose to the heart. This study aims to compare the impact of positioning errors in VMAT and TFiF plans for BH left-sided breast treatments.

The electrochemical hydrogen evolution reaction (HER), as a promising route for hydrogen production, demands efficient and robust noble-metal-free catalysts. Doping foreign atoms into an efficient catalyst such as CoSe could further enhance its activity toward the HER. Herein, we developed a solvothermal ion exchange approach to doping S into CoSe nanosheets (NSs).

This study aimed to evaluate the prognostic value of preoperative neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), lymphocyte-monocyte ratio (LMR), and C-reactive protein (CRP) in patients with non-small cell lung cancer (NSCLC).We retrospectively evaluated 254 NSCLC patients who underwent radical surgery between January 2012 and April 2014 in the Sichuan Provincial Cancer Hospital.

IrCo-Pi with an optimized Ir-to-Co ratio (RIr-to-Co) exhibited an intrinsic activity toward the OER superior to the two well-known catalysts: cobalt phosphate (Co-Pi) and iridium phosphate (Ir-Pi).

Electrochemical oxidative degradation (EOD) is a particularly promising technique for removing organic pollutants from wastewater. However, due to the high overpotential of EOD in conventional anode materials, the energy cost of EOD is usually very high, which greatly promotes the search for highly active, stable, and energy-efficient anodic catalysts. Herein, we demonstrated that nickel-foam-supported (NF-supported) β-Ni(OH) (NF/β-Ni(OH)) prepared a facile hydrothermal method could be used as an energy efficient anode for EOD.

Methods: Patients diagnosed with cervical squamous cell carcinoma or adenocarcinoma (FIGO stages IB2 to IIB) at the Yinbin Second People's Hospital between September 2008 and September 2013, were included in this study. Patients were classified into 2 groups based on the treatment received: surgery group (CCRT plus radical surgery) and non-surgery groups (CCRT only).
Background And Purpose: There is paucity of data on the efficacy and toxicity of radiotherapy in rectal cancer (RC) elderly patients. The objective was to identify management strategies and resulting outcomes in RC patients ≥70 years undergoing radiotherapy.
Material And Methods: A retrospective study included consecutive RC patients ≥70 years undergoing rectal radiotherapy.
Background: Some Chinese patients with esophageal squamous cell carcinomaare often treated with single-agent concurrent chemoradiotherapy. However, no results have been reported from randomized controlled clinical trials comparing single-agent with double-agent concurrent chemoradiotherapy. It therefore remains unclear whether these regimens are equally clinically effective.

Through a review of the literature, we discuss the main therapeutic options and the recent developments that improved (and complicated) the management of NSCLC brain metastases patients. Most current validated approaches are local with exclusive or combined surgery, whole brain radiotherapy (WBRT) and stereotactic radiotherapy (SRT).

In this work, we demonstrated that, by introducing FeO particles into solution, the incident light energy-restriction for the photo-catalyzed hydrolysis could be broken and the hydrolysis occurred at the FeO/solution interface. The photo-generated holes on the FeO surface played a key role in oxidizing Ir(iii) to Ir(iv) species and triggered the deposition of IrO.

It is desirable to develop photocathodic materials that exhibit high activity toward photoelectrochemical (PEC) HER at more positive potentials because a higher potential means a lower overpotential for HER. In this work, the CuO/CuO bilayered composites were prepared by a facile method that involved an electrodeposition and a subsequent thermal oxidation.
