Silencing of lncRNA Gm26917 Attenuates Alveolar Macrophage-mediated Inflammatory Response in LPS-induced Acute Lung Injury Via Inhibiting NKRF Ubiquitination.

The inflammatory response mediated by alveolar macrophages plays a crucial role in the development of acute lung injury. Numerous studies have reported that lncRNAs are highly expressed in acute lung injury in mouse models and cell lines, and acute lung injury (ALI) can be effectively alleviated by targeting these lncRNAs. The aim of this study was to explore the mechanism by LncRNA Gm26917 regulates the inflammatory response in alveolar macrophages during acute lung injury mouse model.

Effectiveness of non-pharmacological interventions to prevent enteral nutrition intolerance in ICU patients: A network meta-analysis.

Background: Enteral nutrition is beneficial for improving the clinical outcomes of intensive care unit patients. However, enteral nutrition intolerance is a common complication in intensive care unit patients undergoing enteral nutrition.

Aims: We aimed to assess the effectiveness of non-pharmacological interventions in preventing enteral nutrition intolerance in intensive care unit patients and to identify the optimal non-pharmacological interventions.

Electron-Donating Zr Induces Suppressed Ru Over-Oxidation and Accelerated Deprotonation Process Toward Efficient and Durable Water Electrolysis.

The scarcity of cost-effective and durable iridium-free anode electrocatalysts for the oxygen evolution reaction (OER) poses a significant challenge to the widespread application of the proton exchange membrane water electrolyzer (PEMWE). To address the electrochemical oxidation and dissolution issues of Ru-based electrocatalysts, an electron-donating modification strategy is developed to stabilize WRuO under harsh oxidative conditions. The optimized catalyst with a low Zirconium doping (Zr, 1 wt.

A Robust, Biodegradable, and Fire-Retardant Cellulose Nanofibers-Based Structural Material Fabricated from Natural Sargassum.

With increasing concern about the environmental pollution of petrochemical plastics, people are constantly exploring environmentally friendly and sustainable alternative materials. Compared with petrochemical materials, cellulose has overwhelming superiority in terms of mechanical properties, thermal properties, cost, and biodegradability. However, the flammability of cellulose hinders its practical application to a certain extent, so improving the fire-retardant properties of cellulose nanofiber-based materials has become a research focus.

Innovative strategies for designing and constructing efficient fuel cell electrocatalysts.

Polymer electrolyte membrane fuel cells (PEMFCs) are one of the most promising energy conversion devices due to their high efficiency and zero emission; however, two major challenges, high cost and short lifetime, have been hindering the commercialization of fuel cells. Achieving low-Pt or non-precious metal oxygen reduction reaction (ORR) electrocatalysts is one of the main research ideas in this field. In this review, the degradation mechanism of Pt-based catalysts is firstly explained and elucidated, and then five strategies are suggested for the reduction of Pt usage without loss of activity and durability: modulation of metal-support interactions, optimization of local ionomers and mass transport, modulation of composition, modulation of structure, and multi-site synergistic effects.
