Numerous studies in Gram-negative bacteria have focused on the Type VI Secretion Systems (T6SSs), Quorum Sensing (QS), and social behavior, such as in biofilms. These interconnected mechanisms are important for bacterial survival; T6SSs allow bacteria to battle other cells, QS is devoted to the perception of bacterial cell density, and biofilm formation is essentially controlled by QS. Here, we...

Quorum sensing (QS) is a chemical communication process that Pseudomonas aeruginosa uses to regulate virulence and biofilm formation. Disabling of QS is an emerging approach for combating its pathogenicity. Silver nanoparticles (AgNPs) have been widely applied as antimicrobial agents against human pathogenic bacteria and fungi, but not for the attenuation of bacterial QS. Here we mycofabricated...

Burkholderia glumae is a motile plant pathogenic bacterium that has multiple polar flagella and one LuxR/LuxI-type quorum sensing (QS) system, TofR/TofI. A QS-dependent transcriptional regulator, QsmR, activates flagellar master regulator flhDC genes. FlhDC subsequently activates flagellar gene expression in B. glumae at 37°C. Here, we confirm that the interplay between QS and temperature is cr...

A key contemporary trend emerging in big data science is the quantified self (QS)-individuals engaged in the self-tracking of any kind of biological, physical, behavioral, or environmental information as n=1 individuals or in groups. There are opportunities for big data scientists to develop new models to support QS data collection, integration, and analysis, and also to lead in defining open-a...

The paradigm of bacterial quorum sensing (QS), which mediates cell-density-dependent gene expression, usually has been studied in high-cell-density planktonic liquid cultures or in biofilms in which signal concentrations accumulate to sufficiently high levels to induce QS. Presumably under conditions with restricted diffusion of the signal molecule, smaller population sizes could achieve such a...

Jó lenne, ha rendelkeznénk a világ egyetemeinek objektív minőségi sorrendjét ismertető táblázattal. Azt, hogy ilyennel nem rendelkezünk, itt QS rangsor példáján mutatjuk be. Ebben cikkben megvizsgáljuk, milyen összetevői vannak QS-helyezéseknek, ezt különböző magyar egyetemek hogyan teljesítik, és vajon ezek mutatók mivel korrelálnak legjobban. Kilenc egyetem adatainak felhasználásával azt meg,...

BACKGROUND This exploratory study investigated the motives of medical students (N = 63) for using indirect questions of the type I don't know if [you have already heard about chemotherapies], I don't know how [you are], or I don't know what [you do for a living] in simulated patient interviews during a communication skills course. METHODS I don't know questions (IDK-Qs) were observed during t...

Quorum sensing (QS) is a microbial cell-to-cell communication process that relies on the production and detection of chemical signals called autoinducers (AIs) to monitor cell density and species complexity in the population. QS allows bacteria to behave as a cohesive group and coordinate collective behaviors. While most QS receptors display high specificity to their AI ligands, others are quit...

We study the quantum summation (QS) algorithm of Brassard, HHyer, Mosca and Tapp, see 1], which approximates the arithmetic mean of a Boolean function deened on N elements. We present sharp error bounds of the QS algorithm in the worst-average setting with the average performance measured in the Lq norm, q 2 1; 1]. We prove that the QS algorithm with M quantum queries, M < N, has the worst-aver...

Bacterial quorum sensing (QS) is a density dependent communication system that regulates the expression of certain genes including production of virulence factors in many pathogens. Bioactive plant extract/compounds inhibiting QS regulated gene expression may be a potential candidate as antipathogenic drug. In this study anti-QS activity of peppermint (Mentha piperita) oil was first tested usin...
