Subchronic Exposure to Arsenic and Nickel Triggers Nitrosative Stress and Histological Alterations in the Rat Liver

Journal of Applied Toxicology, EarlyView.
ABSTRACT Environmental exposure to heavy metals poses a threat to human health. Several studies documented harmful effects on the liver after arsenic and nickel exposure at concentrations beyond permissible limits. Nevertheless, the impact of a simultaneous exposure to both elements on hepatic biochemistry and histology remains unelucidated. Therefore,

Reidite Formation From Zircon Subjected to 20, 40, and 60 GPa Shock Experiments

Journal of Raman Spectroscopy, EarlyView.
Structure disordering as a result of shock pressure: In zircon shocked from 20 to 60 GPa, the shock‐induced structural disorder increases with increasing shock pressure (gray area). Shock disorder of zircon is an integral part of its transformation to reidite: Reidite occurs after amorphous material.

AidP, a novel N-Acyl Homoserine Lactonase gene from Antarctic Planococcus sp. [PDF]

, 2017
Planococcus is a Gram-positive halotolerant bacterial genus in the phylum Firmicutes, commonly found in various habitats in Antarctica. Quorum quenching (QQ) is the disruption of bacterial cell-to-cell communication (known as quorum sensing), which has ...

Efficient and Durable Semitransparent Perovskite Solar Cells for the Application in 4T Perovskite/c‐Si Tandem Devices

Progress in Photovoltaics: Research and Applications, EarlyView.
We present an optimized fabrication strategy incorporating a solution‐processed SnO2 buffer layer that prevents sputter‐induced damage during TCO deposition, enabling semitransparent perovskite solar cells with 21.87% efficiency, 27.15% in tandem, and exceptional long‐term stability under continuous illumination and outdoor conditions.

Scalable Flow Reactors for Stable Biofilm Formation and Continuous Whole‐Cell Catalysis

Small, EarlyView.
Flow‐induced deposition enables the controlled formation of stable and long‐lived E. coli biofilms in modular, scalable microfluidic reactors. Hydrodynamic design principles, mechanistic insight into biofilm architecture and long‐term whole‐cell biocatalysis together establish a versatile platform for continuous microbial processing and the engineering

Quorum-quenching activity of some Iranian medicinal plants

New Microbes and New Infections, 2021
Anti-quorum sensing (QS) or quorum quenching (QQ) is known as a new anti-bacterial strategy to combat bacterial infection. One of the best candidates for this strategy is a natural plant or traditional herbal medicine. This review aimed to summarize and introduce Iranian medicinal plants with anti-QS properties.

Purification and characterisation of a quorum quenching AHL-lactonase from the endophytic bacterium Enterobacter sp. CS66. [PDF]

, 2018
The quorum quenching (QQ) activity of endophytic bacteria associated with medicinal plants was explored. Extracts of the Gram-negative Enterobacter sp. CS66 possessed potent N-acylhomoserine lactone (AHL) hydrolytic activity in vitro.

Aptamer‐mediated outer membrane destabilization overcomes low permeability resistance in Pseudomonas aeruginosa

The FEBS Journal, EarlyView.
DNA aptamers, Apt 60 and Apt 173, target the BamA protein to compromise outer membrane integrity in Pseudomonas aeruginosa, making it susceptible to Azithromycin, an antibiotic that is otherwise poorly effective due to the low‐permeability membrane.

Rice and bean AHL-mimic quorum-sensing signals specifically interfere with the capacity to form biofilms by plant-associated bacteria [PDF]

, 2013
Many bacteria regulate their gene expression in response to changes in their population density in a process called quorum sensing (QS), which involves communication between cells mediated by small diffusible signal molecules termed autoinducers.
