Neoadjuvant adebrelimab combined with chemotherapy (cisplatin/carboplatin and etoposide) for limited-stage small-cell lung cancer: a study protocol of phase 2 trial (NIUS).

Introduction: Small-cell lung cancer (SCLC) is a highly malignant neuroendocrine tumour, and concurrent chemoradiotherapy is the current recommended treatment for limited-stage SCLC. However, the overall survival (OS) of patients with SCLC remains poor. Therefore, improving the survival of patients with SCLC and benefitting more patients are urgent clinical requirements.

Association of α-klotho concentrations with cardiovascular and all-cause mortality in American adults with depression: a national prospective cohort study.

This study examines α-klotho levels in depressed American adults and their association with cardiovascular disease and all-cause mortality, utilizing data from the National Health and Nutrition Examination Survey (2007-2016) and mortality details from the National Death Index up to December 31, 2019. Including 3329 participants with depression, findings revealed 485 all-cause and 113 cardiovascular deaths. To investigate the nonlinear association between α-klotho and mortality, the Cox proportional hazards regression model, restricted cubic splines, and two-piecewise Cox proportional hazards model were developed.

Gradient Luminescence Enhancement in Organic Metal Halide Perovskites via the Suppression of [SbCl] Unit Distortion.

Intrinsic stereochemical activity of the 5s electron configuration in Sb leads to structural distortion within [SbCl] units, which, while stabilizing the material, paradoxically diminishes luminescence intensity due to induced asymmetry. To address this issue, a strategy, which encompasses increasing the structural dimensions and introducing In doping, was developed to mitigate the geometrical distortion in the [SbCl] units within the metal-organic perovskite (DABCO)SbCl·HO and (DABCO)SbCdCl·2HO (DABCO = triethylenediamine). This dimensional augmentation confines lattice distortion effectively, and the In doping modifies the 5s electron configuration of Sb, thereby reducing the distortion at its origin.

Efficient Organic Light-Emitting Diodes Obtained by Introducing Gadolinium (Gd) Complexes Based on Pyrazolone Derivative Ligands as Hole Trappers.

The utilization of lanthanide (Ln) complexes in the realm of organic light-emitting diodes (OLEDs) has garnered extensive interest, particularly in their role as luminescent materials or electron trappers. A series of gadolinium (Gd) complexes with energy levels of high HOMO/LUMO and different triplet state energies were designed and synthesized by introducing substituents with different electronic effects onto the pyrazolone derivative ligands. Subsequently, these complexes were precisely purified by vacuum sublimation and codoped into the light-emitting layer (EML) of the OLEDs.

Blue light-driven cell cycle arrest in thyroid cancer via Retinal-OPN3 complex.

Background: Papillary thyroid carcinoma (PTC) is the most common type of thyroid malignancy, with a rising incidence. Traditional treatments, such as thyroidectomy and radiotherapy, often lead to significant side effects, including impaired thyroid function. Therefore, there is an urgent need for non-invasive therapeutic approaches.

Generation of squeezed vacuum state in the millihertz frequency band.

The detection of gravitational waves has ushered in a new era of observing the universe. Quantum resource advantages offer significant enhancements to the sensitivity of gravitational wave observatories. While squeezed states for ground-based gravitational wave detection have received marked attention, the generation of squeezed states suitable for mid-to-low-frequency detection has remained unexplored.

Enhancement of NIR-II Emission of Er by Doping Fe in Double Perovskites: Multimode Luminescence for Versatile Optoelectronic Applications.

Erbium ions are commonly used to extend the photoelectric properties of metal halide perovskites from visible to near-infrared range. However, achieving high-efficiency multimode luminescence in a single system is difficult due to the weak absorption associated with forbidden 4f-4f transitions. In this study, a unique strategy is proposed to adjust multimode luminescence and enhance the second near-infrared region (NIR-II) emission in CsNaBiCl by incorporating Fe ions.

The Optimal Time of High-Intensity Pre-rehabilitation for Surgical Lung Cancer Patients: A Retrospective Cohort Study with 4452 Patients.

Engineering of -CN for Photocatalytic Hydrogen Production: A Review.

Graphitic carbon nitride (-CN)-based photocatalysts have garnered significant interest as a promising photocatalyst for hydrogen generation under visible light, to address energy and environmental challenges owing to their favorable electronic structure, affordability, and stability. In spite of that, issues such as high charge carrier recombination rates and low quantum efficiency impede its broader application. To overcome these limitations, structural and morphological modification of the -CN-based photocatalysts is a novel frontline to improve the photocatalytic performance.

Surface Microstructure Drives Biofilm Formation and Biofouling of Graphene Oxide Membranes in Practical Water Treatment.

Significant progress has been made previously in the research and development of graphene oxide (GO) membranes for water purification, but their biofouling behavior remains poorly understood. In this study, we investigated the biofilm formation and biofouling of GO membranes with different surface microstructures in the context of filtering natural surface water and for an extended operation period (110 days). The results showed that the relatively hydrophilic and smooth Fe(OH)/GO membrane shaped a thin and spatially heterogeneous biofilm with high stable flux.
