What Is the Mechanism by which the Introduction of Amorphous SeO Effectively Promotes Urea-Assisted Water Electrolysis Performance of Ni(OH)?

Nickel hydroxide (Ni(OH)) is considered to be one of the most promising electrocatalysts for urea oxidation reaction (UOR) under alkaline conditions due to its flexible structure, wide composition and abundant 3D electrons. However, its slow electrochemical reaction rate, high affinity for the reaction intermediate *COOH, easy exposure to low exponential crystal faces and limited metal active sites that seriously hinder the further improvement of UOR activities. Herein it is reported electrocatalyst composed of rich oxygen-vacancy (O) defects with amorphous SeO-covered Ni(OH) (O-SeO/Ni(OH)).

A responsive cocktail nano-strategy breaking the immune excluded state enhances immunotherapy for triple negative breast cancer.

The exclusion of immune cells from the tumor can limit the effectiveness of immunotherapy in triple negative breast cancer (TNBC). The cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway plays a crucial role in priming adaptive anti-tumor immunity through the production of type I interferons (IFNs), facilitating the maturation of dendritic cells (DCs) and the function of T cells. Although the increased expression of programmed death-ligand 1 (PD-L1) upon STING activation is favorable for amplifying the efficacy of immune checkpoint inhibitors (ICIs) and realizing combination therapy, the penetration barrier remains a major obstacle.

Growth of microbes in competitive lifestyles promotes increased ARGs in soil microbiota: insights based on genetic traits.

Background: The widespread selective pressure of antibiotics in the environment has led to the propagation of antibiotic resistance genes (ARGs). However, the mechanisms by which microbes balance population growth with the enrichment of ARGs remain poorly understood. To address this, we employed microcosm cultivation at different antibiotic (i.

Priority analysis of educational needs related to geriatric nursing competence among Chinese undergraduate nursing students: Application of Borich needs assessment, importance-performance analysis and locus for focus model.

Aim: This study aimed to assess and identify the priority of educational needs for geriatric nursing competence among Chinese undergraduate nursing students.

Background: The increased aging population puts new challenges in geriatric nursing care. Competence in geriatric nursing is essential for nursing students to be well-equipped to be qualified nurses in their future work to meet the growing demand for geriatric nursing.

Preparation, mechanism, and biological applications of targeting LDs ratiometric fluorescent probes for HClO detection.

Hypochlorous acid (HClO) is a well-known inflammatory signaling molecule, while lipid droplets (LDs) are dynamic organelles closely related to inflammation. Using organic small-molecule fluorescence imaging technology to target LDs for precise monitoring of HClO is one of the most effective methods for diagnosing inflammation-related diseases. A thorough investigation of how probes detect biological markers and the influencing factors can aid in the design of probe molecules, the selection of high-performance tools, and the accuracy of disease detection.
