Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)

Advanced Functional Materials, EarlyView.
Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by

Revelation of early repolarization by eliminating accessory pathway in manifest Wolff–Parkinson–White syndrome: A case report

Journal of Arrhythmia, 2019
A 23‐year‐old male with manifest Wolff–Parkinson–White syndrome presented with a first occurrence of ventricular fibrillation (VF). Initially, we anticipated the occurrence of atrial fibrillation, causing rapid antegrade conduction over the accessory ...

Longitudinal dissociation of atrioventricular accessory pathways

Journal of the American College of Cardiology, 1991
Unusual properties of atrioventricular (AV) accessory pathways were found during electrophysiologic investigations in four patients (three men and one woman). Anterograde longitudinal dissociation of the accessory pathway was observed in two patients and retrograde longitudinal dissociation in two others.

Expanding Chemical Space of Nucleic Acid Nanoparticles for Tunable Antiviral‐Like Immunomodulatory Responses and Potent Adjuvant Activity

Advanced Functional Materials, EarlyView.
We introduce a nucleic acid nanoparticle (NANP) platform designed to be rrecognized by the human innate immune system in a regulated manner. By changing chemical composition while maintaining constant architectural parameters, we identify key determinants of immunorecognition enabling the rational design of NANPs with tunable immune activation profiles

Successful Ablation of Antero-septal Accessory Pathway in the Non-Coronary Cusp in a Child

Indian Pacing and Electrophysiology Journal, 2012
A 15-year-old boy with Wolff-Parkinson-White syndrome underwent an electrophysiology study for symptoms of palpitations and persistence of pre-excitation during peak exercise.

A long slanted transseptal accessory pathway

Journal of the Chinese Medical Association, 2011
A 63-year-old male with Wolff-Parkinson-White syndrome was admitted for ablation of accessory pathway. Intracardiac electrogram revealed a left-side accessory pathway during tachycardia, which was successfully ablated from the right posterior tricuspid annulus because of a long slanted transseptal accessory pathway (2.2 cm).

Bimetallic Nanoreactor Activates cGAS‐STING Pathway via mtDNA Release for Cancer Metalloimmunotherapy

Advanced Functional Materials, EarlyView.
A bimetallic Mn–Ca nanoreactor (MCC) is developed as a non‐nucleotide STING nanoagonist for cancer metalloimmunotherapy. MCC induces Ca2+ overload and hydroxyl radical generation, resulting in mitochondrial damage and mtDNA release. The released mtDNA cooperates with Mn2+ to robustly activate cGAS–STING signaling.

Catheter ablation of anteroseptal accessory pathways from the aortic cusps: A case series and a review of the literature

Journal of Arrhythmia, 2016
Data regarding catheter ablation of anteroseptal accessory pathways through the aortic cusps are limited. We describe two cases of true para-Hisian accessory pathways successfully ablated from the aortic cusps (right coronary cusp and non-coronary cusp ...

Synergistic Compatibilization of CsPbBr3 Perovskites and HfO2 Nanocrystals for Hybrid Sensitized Nanoscintillators

Advanced Functional Materials, EarlyView.
Lead halide perovskite nanocrystals are promising scintillators but suffer from reabsorption losses and limited compatibility with high‐Z additives. Hybridization of CsPbBr3 nanocrystals with PbBr2‐passivated HfO2 nanoparticle sensitizers, achieved during or after synthesis, produces stable composites with maintained optical quality, improved ...
