The ionophore resistance genes narA and narB are geographically widespread and linked to resistance to medically important antibiotics

open access: yesmSphere
Ionophores are a class of antibiotics used widely in animal production as anti-coccidials and for growth promotion. Since ionophores are not used in human medicine, it has largely been assumed that they do not contribute to medically important ...

Microfluidic Nano‐Assembly of Red‐Blood‐Cell (RBC) Lipids and Components for Engineering Extracellular Vesicles

open access: yesAdvanced Healthcare Materials, EarlyView.
Engineered red blood cell‐derived extracellular vesicles (eRBCEVs) are synthesized via controlled microfluidic assembly from native RBC lipids, enabling tunable encapsulation of proteins, nucleic acids, nanoparticles, and viral vectors. The platform demonstrates reproducible nanoscale architecture, preserved membrane composition, and functional cargo ...

New dual ionophore immunosensor concept modeling and experimental support [PDF]

open access: yes, 2010
Literature shows that ion-selective electrodes (ISEs) can be modified to create a potentiometric immunoassay by covalent attachment of a hapten to the ionophore and use of immunocompetition to modulate transmembrane ion flux.

Reorganization of Innate Immune Cell Lipid Profiles by Bioinspired Meroterpenoids to Limit Inflammation

open access: yesAdvanced Science, EarlyView.
Resolution pharmacology is an emerging strategy to tackle inflammatory pathologies. Bioinspired meroterpenoids induce a lipid mediator class switch toward inflammation resolution in vitro and in vivo by targeting key nodes in lipid mediator biosynthesis and neutral lipid dynamics.
