Inactivation of MexT in Pseudomonas aeruginosa PAO1 destabilizes cooperation and favors the emergence of a unique quorum sensing variant

Journal of Bacteriology
Pseudomonas aeruginosa, an opportunistic Gram-negative pathogen, uses a cell-cell signaling system called quorum sensing to coordinate group behaviors. Quorum sensing in P. aeruginosa is a model to study cooperative behaviors in populations.

Quorum Sensing in Fungi: Q&A

PLoS Pathogens, 2011
I know that the accumulation of certain molecules called ‘‘quorum-sensing factors’’ in bacteria, as cultures grow dense, can control group behavior and that these include virulence traits and the formation of drug-resistant microbial biofilms. I am familiar with some of the molecules that mediate the sensing of organism density such as homoserine ...

Microbial quorum sensing: a tool or a target for antimicrobial therapy?

, 2009
Inter-cell communication aided by released chemical signals when cell density reaches a critical concentration has been investigated for over 30 years as quorum sensing.

LitR and its quorum-sensing regulators modulate biofilm formation by Vibrio fischeri

Journal of Bacteriology
Quorum sensing controls numerous processes ranging from the production of virulence factors to biofilm formation. Biofilms, communities of bacteria that are attached to one another and/or a surface, are common in nature, and when they form, they can ...

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,

Air Pollution Quinones Impair Intestinal Barrier Integrity and Endoplasmic Reticulum in Differentiated Caco‐2 Cells

Journal of Applied Toxicology, EarlyView.
ABSTRACT Particulate matter (PM) is a major global health threat, linked to millions of deaths annually. Beyond inhalation, PM components reach the gastrointestinal tract through the mucociliary escalator or contaminated food and water. Among PM's organic fraction, redox‐active quinones such as 1,2‐naphthoquinone (NQ) and 9,10‐phenanthrenequinone (PQ ...

The effect of calcium and magnesium on the aggregation of a purple phototrophic bacteria mixed consortium

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND An essential aspect of applying Purple Phototrophic Bacteria (PPB) technology for wastewater treatment is the biomass separation from the aqueous phase. Ca2+ and Mg2+ have been used to enhance the aggregation of different biological matrices. In this paper, the effect of Ca2+ and Mg2+ on the aggregation of a mixed culture of PPB was

Correlating Mid‐Infrared Absorption With Radiative Efficiency in Passive Daytime Radiative Cooling Systems

Macromolecular Rapid Communications, EarlyView.
We establish a correlation between the mid‐IR photonic response of Passive Daytime Radiative Cooling systems and their thermal radiation performances, characterized within a dedicated setup that simulates the irradiance toward outer space under controlled and reproducible conditions.
