Control of Bacterial Attachment on Macroporous PDMS/Paraffin SLIPS With Varying Lubricant Viscosity

Advanced Materials Interfaces, EarlyView.
Slippery liquid‐infused porous surfaces (SLIPS) prepared from macroporous PDMS, infused with medical‐grade paraffins, were systematically investigated regarding the correlation of viscosity, surface corrugation, bulk porosity, and bacterial resistance. Substrate porosity was found to dominate lubricant stabilization and the antifouling activity.

Chemical Inhibition of Pyocyanin Biosynthesis Attenuates Virulence of Pseudomonas aeruginosa

Angewandte Chemie, EarlyView.
Anti‐virulence strategies disarm pathogens rather than killing them directly. A β‐lactone reduces pyocyanin production without affecting growth. Chemical proteomics identified PqsC as the primary target via binding to Cys129. Crystallography revealed the binding mode, and SAR yielded a chloroacetamide inhibitor with improved enzymatic potency and anti ...

Interference of bacterial cell-to-cell communication: A new concept of antimicrobial chemotherapy breaks antibiotic

Frontiers in Microbiology, 2013
Bacteria use a cell-to-cell communication activity termed Quorum sensing to coordinate group behaviors in a cell-density dependent manner. Quorum sensing influences the expression profile of diverse genes, including antibiotic tolerance and virulence ...

TNAP and PHOSPHO1 Function Synergistically to Afford Critical Control Over the Mineralization of the Postnatal Murine Skeleton

Advanced Science, EarlyView.
Biomineralization underpins skeletal development, yet its molecular control remains incompletely understood. Using a novel murine knockout model, this study reveals the essential and complementary roles of PHOSPHO1 and TNAP in postnatal skeletal development.

Puerarin‑Loaded pH‑Responsive ZIF‑90 Nanoparticles Ameliorate Osteoporosis via Enhancing H3K18 Lactylation and Suppressing Aberrant Osteoclast Activation

Advanced Science, EarlyView.
Schematic illustration of the mechanism by which ZIF‐90@PU alleviates osteoporosis via H3K18la‐mediated NFATc1 pathway suppression. ABSTRACT Osteoporosis is characterized by dysregulated osteoclast activity, leading to excessive bone resorption and structural damage.

Quorum-sensing inhibitors as anti-pathogenic drugs

International Journal of Medical Microbiology, 2006
Quorum-sensing (QS) signalling systems of pathogens are central regulators for the expression of virulence factors and represent highly attractive targets for the development of novel therapeutics. In Pseudomonas aeruginosa, QS systems are also involved in elevated antibiotic tolerance of biofilms as well as elevated tolerance to the activity of the ...
