Article Synopsis
  • Recent advancements in enhancing the quantum yield (QY) of trivalent lanthanide (Ln) ion-based nanoparticles have been made using photosensitization methods involving host matrices or organic ligands.
  • These nanoparticles exhibit great fluorescent properties, such as long emission lifetimes and high photostability, which make them promising alternatives to traditional fluorescent materials like organic dyes and quantum dots, despite their generally low QYs.
  • The review highlights photosensitization principles, focuses on nanoparticles containing Eu, Tb, and Dy ions, and discusses their potential applications in biomedical fluorescent imaging (FI).

Article Synopsis
  • This study investigates pulmonary fibrosis-like changes in critically ill patients with SARS-CoV-2 pneumonia during two different variant periods: delta and pre-delta.
  • Clinical data and chest CT images were analyzed from a total of 184 patients across two time periods, revealing that those infected during the delta variant period displayed more severe fibrosis-like changes.
  • The findings indicate that patients during the delta period had a higher frequency of significant fibrotic changes compared to the pre-delta group, suggesting the delta variant may be associated with worse pulmonary outcomes.
