Fibre Bragg grating fabrication in germanosilicate fibres with 244nm femtosecond laser light

, 2006
The ability to fabricate strong and extraordinarily stable Bragg gratings in any type of fibre using femtosecond laser light has attracted much interest in the recent past. The induced index change has been attributed to glass densification brought about

A Novel IDO1/NE Dual Inhibitor, IMM‐H018 Prevents the Primary and Secondary Sepsis and Ameliorates the Kidney Injury Through Inhibiting the Cytokine Storm and Microthrombosis, and Reversing Immunosuppression

Advanced Science, EarlyView.
IMM‐H018, a dual IDO1/NE inhibitor, demonstrates potent therapeutic efficacy in sepsis by simultaneously targeting excessive inflammation and immune dysfunction. It prevents both primary and secondary sepsis through anti‐inflammatory, immune‐restoring, and renoprotective mechanisms, reducing organ damage, improving immune homeostasis, preserving kidney

Cation Diffusion‐Mediated Displaced Reaction‐Transformation in Green Steelmaking

Advanced Science, EarlyView.
The removal of O lattice atoms by environmental H2 at the surface of Fe3O4 results in Fe enrichment, driving the inward diffusion of Fe cations into the bulk. Through hopping between unoccupied and initially occupied sites, cation diffusion triggers a spatially displaced reaction‐transformation and drives subsequent dynamic phase transformations and ...

Membrane‐Active Peptide Protects Against Inflammation by Targeting NLRP3 Activation at the Trans‐Golgi Network

Advanced Science, EarlyView.
The membrane‐active peptide Pep19‐2.5 reduces harmful inflammation by blocking activation of the NLRP3 inflammasome at trans‐Golgi network membranes. By targeting key membrane interactions, Pep19‐2.5 suppresses inflammatory IL‐1β production and alleviates allergic airway inflammation in mice, leading to reduced immune cell infiltration and improved ...

Hollow Cu2O Nanozymes Enhance Probiotic Therapy for Colitis via Redox Homeostasis and TXNIP/NLRP3 Inflammasome Inhibition

Advanced Science, EarlyView.
Hollow cuprous oxide (H‐Cu2O) nanozymes feature enlarged catalytic surfaces for superior reactive oxygen species (ROS) scavenging. By efficiently neutralizing mucosal ROS, H‐Cu2O directly suppresses the TXNIP/NLRP3 inflammasome axis and restores intestinal epithelial barrier integrity.
