Advanced Science, EarlyView.Under 660 nm visible light, Ru NCs efficiently photocatalyze nitrate‐to‐ammonium conversion and modulate oral nitrogen metabolism. They precisely perturb Veillonella parvula, block its key support to Porphyromonas gingivalis, and exert an “inhibiting without killing” antivirulence effect.

Synthesis of Silver Nanoparticles by a Bryophilous Rhizoctonia species
Nanomaterials and Nanotechnology, 2013 We demonstrate the synthesis of silver nanoparticles by a potentially benign species of bryophilous Rhizoctonia in two different media. The first medium supports fungal growth and the up‐regulation of nitrate reductase, while the second medium supports ...

Advanced Science, EarlyView.An integrated probiotic system is engineered to execute a programmed therapeutic cascade against inflammatory bowel disease. Upon pathological signals, the system sequentially performs ROS scavenging, tungsten release, and selective pathogen suppression, thereby breaking the oxidative stress–dysbiosis cycle to remodel gut microbiota and reinforce ...

Advanced Science, EarlyView.A biomimetic GOx/Arg‐loaded nanoplatform produces nitric oxide through an in situ catalytic cascade reaction, enabling dual‐target metabolic regulation in diabetes‐associated biofilm infections. Bacterial metabolism is disrupted, and macrophage immunometabolism is reprogrammed, resulting in biofilm eradication, immune restoration, and enhanced ...

Functional diversity in nutrient acquisition by ectomycorrhizal fungi [PDF]
, 2008 Nutrient uptake by boreal forest trees depends upon the symbiotic ectomycorrhizal (ECM) fungi that colonise more than 95% of the fine roots. In these ecosystems, nitrogen (N) is the most important growth-limiting nutrient for plants, followed by ...

Uncovering Cystic Fibrosis Carrier: Insights From a Heterozygous CFTR‐F508del Rabbit Model
International Forum of Allergy &Rhinology, EarlyView.ABSTRACT Background Chronic rhinosinusitis (CRS) is a heterogeneous inflammatory disorder frequently associated with impaired mucociliary clearance and bacterial infection. Individuals carrying a single cystic fibrosis transmembrane conductance regulator (CFTR) mutation exhibit partial CFTR dysfunction and are increasingly recognized as being at risk ...
