Global convergence of quorum-sensing networks [PDF]

, 2010
In many natural synchronization phenomena, communication between individual elements occurs not directly, but rather through the environment. One of these instances is bacterial quorum sensing, where bacteria release signaling molecules in the ...

Quorum-Sensing Inhibition

, 2014
As the elucidation of the molecular mechanisms behind quorum sensing (QS) gained momentum, researchers conceived several strategies to block QS systems. Indeed, QS signals can be detected in biofilms across a range of environments. For example, biofilms grown on rocks in the San Marcos River in Texas have been shown to produce acyl-homoserine lactone ...

Peptide Display Directed Assembly of Biopolymer Core–Silica Shell Particles

Advanced Healthcare Materials, EarlyView.
Bacterial cells are engineered to produce biopolyester particles displaying peptides mediating growth of silica. Peptide‐coated biopolyester particles are treated with silica precursors and silica shell formation is studied. Transmission electron microscopy shows silica‐coated BPs which are formed after the silicification treatment. Characterization of

Mechanical Reinforced and Self‐healing Hydrogels: Bioprinted Biomimetic Methacrylated Collagen Peptide‐Xanthan Gum Constructs for Ligament Regeneration

Advanced Healthcare Materials, EarlyView.
Readily UV‐curing and self‐healing methacrylated collagen peptide (COPMA) hydrogels are developed with tunable mechanical properties. As the interpenetrating network between COPMA and xanthan gum (XG), COPMA‐XG bioinks show improved mechanical properties, printability, and stability, compared to COPMA or XG.

Social Evolution Selects for Redundancy in Bacterial Quorum Sensing.

PLoS Biology, 2016
Quorum sensing is a process of chemical communication that bacteria use to monitor cell density and coordinate cooperative behaviors. Quorum sensing relies on extracellular signal molecules and cognate receptor pairs. While a single quorum-sensing system

High Rate Capability and Cycling Stability in Multi‐Domain Nanocomposite LiNi1–xTi3x/4O2 Positive Electrodes

Advanced Materials, EarlyView.
By targeting nominally non‐stoichiometric LiNi1–xTi3x/4O2 compositions, a multi‐domain nanocomposite rock salt positive electrode material with exceptional cycling stability and excellent rate performance is obtained. This enhanced performance particularly under high oxidative potential protocols and cell electrode mass loadings applicable to ...

Preclinical common data elements for general pharmacological studies (pharmacokinetic sample collection, tolerability, and drug administration). A report of the TASK3‐WG1A General Pharmacology Working Group of the ILAE/AES Joint Translational Task Force

Epilepsia Open, EarlyView., 2023
Abstract Growing concerns over rigor and reproducibility of preclinical studies, including consistency across laboratories and translation to clinical populations, have triggered efforts to harmonize methodologies. This includes the first set of preclinical common data elements (CDEs) for epilepsy research studies, as well as Case Report Forms (CRFs ...

Bacteria clustering by polymers induces the expression of quorum sense controlled phenotypes [PDF]

, 2013
Bacteria deploy a range of chemistries to regulate their behaviour and respond to their environment. Quorum sensing is one mean by which bacteria use chemical reactions to modulate pre-infection behaviour such as surface attachment.

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

Advanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent
