Biomass‐derived hydrochars as eco‐friendly adsorbents for wastewater treatment applications

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Emerging organic pollutants (EOPs), such as diethyl phthalate (DEP), bisphenol A (BPA), and methylene blue (MB), are only partially removed in conventional wastewater treatment plants. This study assesses hydrochars produced by hydrothermal carbonization (HTC) of spruce bark (SB), vine shoots (VSs), and wheat straw (WSs) for removing three ...

Spatiotemporal Distribution of Pseudomonas aeruginosa Alkyl Quinolones under Metabolic and Competitive Stress

mSphere, 2020
Pseudomonas aeruginosa is an opportunistic human pathogen important to diseases such as cystic fibrosis. P. aeruginosa has multiple quorum-sensing (QS) systems, one of which utilizes the signaling molecule 2-heptyl-3-hydroxy-4-quinolone (Pseudomonas ...

Reaction of aryne with aza-Morita–Baylis–Hillman adducts: Synthesis of 4-quinolones and N-arylation products

Journal of Saudi Chemical Society, 2017
The reaction of aryne with aza-Morita–Baylis–Hillman (aza-MBH) adducts has been studied. Aryne reacts with aza-MBH adducts through a cascade insertion–cyclization–ene reaction to produce 4-quinolones in 18–44% yields; meanwhile, aza-MBH adducts undergo N-

Genomic Insights Into Spatiotemporal Dynamics of Acquired Azithromycin Resistance Genes in Salmonella Strains Worldwide

Food Safety and Health, EarlyView.
ABSTRACT Azithromycin has been used for clinical invasive infections caused by fluoroquinolone‐ and third‐generation cephalosporin‐resistant Salmonella, and mass drug administration with azithromycin has been used to reduce under‐5 mortality in children in some countries.

Inhibiting N-acyl-homoserine lactone synthesis and quenching Pseudomonas quinolone quorum sensing to attenuate virulence [PDF]

, 2015
YesBacteria sense their own population size, tune the expression of responding genes, and behave accordingly to environmental stimuli by secreting signaling molecules. This phenomenon is termed as quorum sensing (QS).

Potent monoclonal antibodies against multidrug‐resistant hypervirulent Klebsiella pneumoniae

Interdisciplinary Medicine, EarlyView.
A novel immunization strategy using a low‐virulence, multidrug‐resistant strain yields synergistic monoclonal antibodies against hypervirulent Klebsiella pneumoniae. These antibodies provide cross‐serotype protection through a dual‐mechanism of pathogen clearance and immunomodulation, offering a promising non‐antibiotic therapeutic for resistant ...

Genomic Insights Into Carbapenem‐Resistant Klebsiella pneumoniae in Pediatric Bloodstream Infections in Zhejiang, China (2019–2024)

Journal of Clinical Laboratory Analysis, EarlyView.
The primary mechanism of carbapenem resistance identified in pediatric CRKP‐BSI strains was the production of Class B metalloenzymes. We report, for the first time, an outbreak of bloodstream infections in a neonatal ward caused by the dissemination of NDM‐1‐producing ST25 K. pneumoniae.
