AI Article Synopsis

  • Cellular membranes play a crucial role in how effectively cell-penetrating peptides (CPPs) deliver substances into cells and how antimicrobial peptides (AMPs) act against bacteria.
  • Lipid oxidation affects the chemical and physical characteristics of membranes, which can impact the interactions with these peptides.
  • The study suggests a potential synergy between oxidized membranes and peptides that act on membranes, indicating that these changes might enhance peptide effectiveness.

Article Abstract

The biophysical properties of cellular membranes intimately influence the delivery of cargoes into cells by cell-penetrating peptides (CPPs) and the bactericidal activity of antimicrobial peptides (AMPs). Here, we discuss how lipid oxidation creates important chemical and biophysical changes in membranes, and hypothesize about the observed synergy between oxidized membranes and membrane-active peptides.

This study aims to explore the efficacy of neutrophil membrane nanovesicles (NMNVs) in the treatment of acute kidney injury caused by sepsis (S-AKI). Moreover, its effects on renal function indicators in plasma [creatinine (CREA), urea (UREA)], oxidative stress factor [malondialdehyde (MDA)], inflammatory factor [myeloperoxidase (MPO), histone H4 (H4), and macrophage inflammatory protein-2 (MIP-2)] are studied. Sixty SPF grade adult male Wistar rats in a healthy state under natural infection were randomly divided into blank, LSP, and experimental groups, with 20 rats in each group.

Ciprofloxacin (CIP) is an extensively used broad-spectrum, fluoroquinolone antibiotic used for treating diverse bacterial infections. Effluent treatment plants (ETPs) worldwide lack technologies to detect or remediate antibiotics. CIP reaches the aquatic phase primarily due to inappropriate disposal practices, lack of point-of-use sensing, and preloaded activated charcoal filter at ETPs.

Highly Tension-Strained Copper Concentrates Diluted Cations for Selective Proton-Exchange Membrane CO2 Electrolysis.

Electrolysis of carbon dioxide (CO2) in acid offers a promising route to overcome CO2 loss in alkaline and neutral electrolytes, but requires concentrated alkali cations (typical ≥3 M) to mitigate the trade-off between low pH and high hydrogen evolution reaction (HER) rate, causing salt precipitation. Here we report a strategy to resolve this problem by introducing tensile strain in a copper (Cu) catalyst, which can selectively reduce CO2 to valuable multicarbon products, particularly ethylene, in a pH 1 electrolyte with 1 M potassium ions. We find that the tension-strained Cu creates an electron-rich surface that concentrates diluted potassium ions, contributing to CO2 activation and HER suppression.

Anticounterfeiting technologies have become increasingly crucial due to the growing issue of counterfeit goods, particularly in high-value industries. Traditional methods such as barcodes and holograms are prone to replication, prompting the need for advanced, cost-effective, and efficient solutions. In this work, a practical application of anodic aluminum oxide (AAO) membranes are presented for anticounterfeiting, which addresses the challenges of high production costs and complex fabrication processes.

The removal of antimony from wastewater using traditional methods such as adsorption and membrane filtration generates large amounts of antimony-containing hazardous wastes, posing significant environmental threats. This study proposed a new treatment strategy to reductively remove and recover antimony from wastewater using an advanced UV/sulfite reduction process in the form of valuable strategic metalloid antimony (Sb(0)), thus preventing hazardous waste generation. The results indicated that more than 99.
