Host PIK3C3 promotes Shigella flexneri spread from cell to cell through vacuole formation.

open access: yesPLoS Pathogens
Shigella flexneri is a human intracellular pathogen responsible for bacillary dysentery (bloody diarrhea). S. flexneri invades colonic epithelial cells and spreads from cell to cell, leading to massive epithelial cell fenestration, a critical determinant

Intraepithelial neutrophils in mammary, urinary and gall bladder infections

open access: yesVeterinary Research, 2019
Neutrophil mobilization is a crucial response to protect the host against invading microorganisms. Neutrophil recruitment and removal have to be tightly regulated to prevent uncontrolled inflammation and excessive release of their toxic content causing ...

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

open access: yesPolymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Supramolecular Surface Functionalization of Single‐Walled Carbon Nanotubes With Conjugated Graft Copolymers

open access: yesJournal of Polymer Science, EarlyView.
Post‐polymerization modification of poly(tetrazine‐co‐fluorene) conjugated polymer via an inverse‐electron‐demand Diels‐Alder reaction (IEDDA) introduces hydroxyl initiators that enable surface‐initiated ring‐opening polymerization (ROP) of lactide.

Scission of electrospun polymer fibres by ultrasonication [PDF]

open access: yes, 2013
In this work we show that sonication alone can be used to scission bulk electrospun membranes into short fibres. The mechanism of such scission events is bubble cavitation stimulated by the ultrasonic probe, followed by bubble implosion.

Incorporation of Natural Antimicrobial Agents Into Thermoplastic Polymers for Food Applications: Strategies, Efficacy, Challenges and Future Directions

open access: yesPackaging Technology and Science, EarlyView.
This graphical abstract summarizes the main strategies for incorporating natural antimicrobial agents into thermoplastic food packaging polymers, including melt processing, surface deposition, controlled release and chemical immobilization. It highlights the major classes of natural antimicrobials, key advantages such as microbial growth reduction and ...

Endocytosis‐independent cytosolic entry of messenger RNA via fluorous bilayer zippering attenuating Toll‐like receptor signaling and enables ischemic tissue salvage

open access: yesSmart Molecules, EarlyView.
The present study establishes a paradigm shift in synthetic mRNA delivery through the convergence of three orthogonal chemistries—perfluoro‐acylation, bio‐orthogonal click cross‐linking, and disulfide reduction—within a single, modular polymer architecture. Abstract A fundamental constraint of conventional messenger RNA (mRNA) delivery systems is their

Printing to Fight Antimicrobial Resistance Through Nano/Microstructured Platforms

open access: yesThe Chemical Record, EarlyView.
Additive manufacturing enables the rational design of structured antimicrobial platforms across multiple length scales, from nanofibrous scaffolds and droplet microreactors to 3D and 4D printed constructs. By engineering confinement, interfacial chemistry, and stimuli‐responsive release, these systems exert localized action through complementary ...

Contribution of endosomal proteins EHD1 and EHD4 to the HIV‐1 replication cycle

open access: yesThe FEBS Journal, EarlyView.
EHD1 and EHD4, two key trafficking proteins, regulate multiple stages of HIV‐1 infection: In producer cells, they help produce fully infectious virus particles, regulate Envelope protein incorporation in a cell‐type‐dependent manner, and limit the accumulation of antiviral IFITM proteins in virions.
