Advanced Science, EarlyView.D4F‐functionalized ceria nanozyme–CasRx nanoparticles preferentially target renal macrophages through SR‐B1‐mediated uptake in ischemia–reperfusion injury. Ceria scavenges excessive ROS, while CasRx silences STING signaling, shifting macrophages toward a less inflammatory, pro‐resolving state and increasing the proportion of regulatory T cells.

Advanced Science, EarlyView.This work designed an injectable metal‐drug supramolecular condensate formed from hafnium ions and alendronate (Hf‐ALN) and loaded with the COX‐2 inhibitor celecoxib (CXB) for synergistic radioimmunotherapy of postoperative osteosarcoma. Mechanistically, upon X‐ray irradiation, Hf enhances radiation energy deposition, ROS generation, and DNA damage ...

Electron spin resonance (ESR) spectroscopy study of dry-cured ham treated with E-beam
, 2012 The generation, accumulation and decay of free radicals in muscle and fat fractions from three varieties of Spanish dry-cured ham treated (0–4 kGy) in an electron accelerator have been studied by electron spin resonance (ESR) spectroscopy.

Advanced Science, EarlyView.Ox‐mtDNA fragments escaping from mitochondria drive robust inflammatory responses. A targeted nanoplatform simultaneously inhibits mitochondrial FEN1‐mediated mtDNA cleavage and scavenges ROS, preventing the generation of immunogenic Ox‐mtDNA fragments. The released SeNPs further promote autophagic clearance of cytosolic mtDNA. Consequently, cGAS‐STING,

Electron Spin Resonance (ESR) Study of Cigarette Smoke by Use of Spin Trapping Techniques [PDF]
Environmental Health Perspectives, 1976 The technique of spin trapping has been applied to the gas phase of cigarette smoke to identify and quantify the radicals present. It was found that radicals could be trapped only if the smoke was filtered. Three spin traps were used: N-tert-butyl-alpha-phenyl nitrone (PBN).

On the local and itinerant properties of the ESR in YbRh2Si2
Science and Technology of Advanced Materials, 2007 Below the Kondo temperature the heavy Fermion compound YbRh2Si2 shows a well defined electron spin resonance (ESR) with local Yb3+ properties. We report a detailed analysis of the ESR intensity which gives information on the number of ESR active centers ...
