Marine biofouling, which is one of the technical challenges hindering the growth of the marine economy, has been controlled using cuprous oxide (Cu2O) nanoparticles due to the exceptional antifouling properties of Cu(I) ions. However, Cu2O nanoparticles have encountered bottlenecks due to explosive releases of Cu+ ions, high toxicity at elevated doses, and long‐term instability. Here, we present a novel method called Redox Concomitant Formation (RCF) for fabricating a hierarchical Cu(I) metal–organic framework polypyrrole (Cu(I)−MOF/PPy) composite. This method enables in situ phase transition via successive redox reactions that change the chemical valence state and coordination mode of Cu(II)−MOF, resulting in a new structure of Cu(I)−MOF while creating a PPy layer surrounded by the hierarchical structure. Owing to the steady release of Cu+ ions from the Cu(I) sites and photothermal properties of PPy, Cu(I)−MOF/PPy exhibits superior and broad‐spectrum resistance to marine bacteria, algae, and surface‐adhered biofilms in complex biological environments, as well as long‐term stability, resulting in 100 % eradication efficiency under solar‐driven heating. Mechanistic insights into successive structural redox reactions and formation using the RCF method are provided in detail, enabling the fabrication of novel MOFs with the desired composition and structure for a wide range of potential applications.

The study aims to evaluate whether rhythm control by catheter ablation is superior to medical therapy for the patients with atrial fibrillation (AF) and heart failure (HF). The literatures were searched by using PubMed, Cochrane Library, Embase, and Web of Science databases up to 12 October 2023. The randomized controlled trials (RCTs) comparing rhythm control using catheter ablation vs. medical therapy in AF patients with HF were pooled. The primary outcomes included all‐cause mortality, HF re‐hospitalization, and stroke, and the secondary outcomes included left ventricular ejection fraction (LVEF), atrial tachyarrythmia recurrence, quality of life (Minnesota Living with Heart Failure Questionnaire score, MLHFQ score), 6 min walking distance (6MWD), the level of N‐terminal B‐type natriuretic peptide precursor (NT‐proBNP), and adverse events. Nine RCTs involving in 2293 patients met the inclusion criteria. Compared with medical therapy, catheter ablation reduced all‐cause mortality [10.07% (121/1201) vs. 15.26% (175/1147), risk ratio (RR):0.60, 95% confidence interval (CI): 0.48–0.74, P < 0.00001, I2 = 0%] and the rate of HF re‐hospitalization (RR: 0.65, P = 0.02, 95% CI: 0.45 to 0.94, I2 = 74%), but had no obvious difference in incidence of stroke (RR: 0.67, P = 0.27, 95% CI: 0.32 to 1.38, I2 = 0%). Catheter ablation enhanced LVEF [mean difference (MD), 6.26%, P < 0.00001, I2 = 89%], reduced AT recurrence (RR: 0.37, P < 0.00001, 95% CI: 0.26 to 0.52, I2 = 89%), improved the quality of life (MLHFQ score) (MD: −6.83, P = 0.003, I2 = 67%), elevated 6MWD (MD: 15.92, P = 0.006, I2 = 76%), and diminished the level NT‐proBNP (MD: −44.19, P < 0.00001, I2 = 75%), but had no significant difference in adverse events [25.81% (310/1201) vs. 30.25% (347/1147), RR: 0.81, 95% CI: 0.65–1.01, P = 0.06, I2 = 55%]. Catheter ablation as rhythm control strategy substantially enhances the survival rate, reduces HF re‐hospitalization, increases the rate of sinus rhythm maintenance, improves the left ventricular function and the quality of life for AF patients with HF, and has similar safety, compared with medical therapy. The rhythm control by catheter ablation may be a better strategy for the AF patients with HF. [ABSTRACT FROM AUTHOR]

1D nanomaterials have attracted great attention due to their outstanding anisotropic and linear structures. A facile method is developed to fabricate 1D copper metal–organic framework nanowires (Cu‐MOF‐NW) through steam‐assisted conversion from Cu‐MOF precursors. During the steam‐assisted conversion, Cu‐MOF precursor gradually dissolves in methanol steam, and then recrystallized into Cu‐MOF‐NW, which shows high aspect ratio of about 600 and identical crystal structure of MOF‐74. As‐prepared Cu‐MOF‐NW with multiscale porous structure can effectively remove cationic dyes even in dye mixture. Moreover, Cu‐MOF‐NW, as an ideal template, is calcined to form Cu nanoparticle‐doped carbon nanofiber with maintaining its 1D morphology, which shows excellent electrocatalytic activity for the non‐enzymatic sensing of glucose.

Reperfusion injury of ischemic stroke, characterized by the uncontrolled production of reactive oxygen species (ROS) and inflammatory reactions, continues to present a major problem in clinical treatment. Neutrophils are forerunners to infiltrate cerebral ischemic regions and contribute to reperfusion injury. Herein, this study reports a tailored "burning the bridges" strategy by designing biomimetic nanozymes (D@HPB@SPM NPs) to diminish reperfusion injury of ischemic stroke. D@HPB@SPM NPs are composed of a sialic acid (SA)‐modified platelet membrane shell and a hollow Prussian blue nanoparticle core loaded with Deoxyribonuclease I (DNase I). Due to the unique binding affinity of SA to L‐selectin, which is abundantly expressed in circulating neutrophils, D@HPB@SPM NPs can effectively hitchhike on neutrophils across the blood‐brain barrier into the injured brain parenchyma after intravenous injection. Following this, neutrophils are activated and unleash D@HPB@SPM NPs through producing neutrophil extracellular traps (NETs). D@HPB@SPM NPs not only relieve oxidative stress injury by efficiently scavenging ROS, but also mitigate neutrophil‐induced reperfusion injury by degrading NETs in a manner similar to "burning the bridges". The encouraging accumulation of D@HPB@SPM NPs to cerebral ischemic regions and their efficient therapeutic efficacy are systematically validated in ischemic stroke rats. This work offers a fresh insight for ischemic stroke treatment. [ABSTRACT FROM AUTHOR]
