Photochromic Color Tuning of Copper-doped Zinc Sulfide Nanocrystals by Control of Local Dopant Environments.
Angew Chem Int Ed Engl
January 2025

Inorganic photochromic materials offer several advantages over organic compounds, including relatively inexpensive and higher thermal stability. However, tuning their color with the same component has remained a significant challenge. In this study, we demonstrate that the photochromic color of Cu-doped ZnS nanocrystals (NCs), which is initially pale yellow before light irradiation, can be tuned from gray to brown by adjusting the surface stoichiometry of Zn and S, which is controlled through the use of thiol and non-thiol ligands.

Introduction: Lung function has been associated with cognitive decline and dementia, but the extent to which lung function impacts brain structural changes remains unclear. We aimed to investigate the association of lung function with structural macro- and micro-brain changes across mid- and late-life.
Methods: The study included a total of 37 164 neurologic disorder-free participants aged 40-70 years from the UK Biobank, who underwent brain MRI scans 9 years after baseline.
Spatioselective Imaging of Noncoding RNAs in Mitochondria via an Organelle-Specific DNA Assembly Strategy.

Precise imaging of noncoding RNAs (ncRNAs) in specific organelles allows decoding of their functions at subcellular level but lacks advanced tools. Here we present a DNA-based nanobiotechnology for spatially selective imaging of ncRNA (e.g.

Int J Surg
January 2025
Department of Cardiovascular Surgery, Xijing Hospital, Xi'an, Shaanxi, China.
Background: The impact of aortic arch (AA) morphology on the management of the procedural details and the clinical outcomes of the transfemoral artery (TF)-transcatheter aortic valve replacement (TAVR) has not been evaluated. The goal of this study was to evaluate the AA morphology of patients who had TF-TAVR using an artificial intelligence algorithm and then to evaluate its predictive value for clinical outcomes.
Materials And Methods: A total of 1480 consecutive patients undergoing TF-TAVR using a new-generation transcatheter heart valve at 12 institutes were included in this retrospective study.
Evaluation of nationwide analysis surveillance for methicillin-resistant within Genomic Medicine Sweden.

National epidemiological investigations of microbial infections greatly benefit from the increased information gained by whole-genome sequencing (WGS) in combination with standardized approaches for data sharing and analysis. To evaluate the quality and accuracy of WGS data generated by different laboratories but analysed by joint pipelines to reach a national surveillance approach. A national methicillin-resistant (MRSA) collection of 20 strains was distributed to nine participating laboratories that performed in-house procedures for WGS.
