Double Helical Plasmonic Antennas

Advanced Functional Materials, EarlyView.
Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Synergistic Osteogenesis After Co‐Administration of cmRNAs Encoding BMP‐2 and BMP‐7 Utilizing a Transcript‐Activated Matrix

Advanced Functional Materials, EarlyView.
This study demonstrates that the dual delivery of BMP‐2/‐7 coding cmRNAs for bone healing is demonstrated as feasible, safe, and highly osteogenic. Compared to single BMP‐2 or BMP‐7 cmRNAs, the combination enhances the production of both mineral and organic components of the extracellular matrix when delivered using a collagen‐HA scaffold, supporting ...

A rare cause of recurrent syncope: chemodectoma of left carotid

Italian Journal of Medicine, 2023
Syncope is a frequent cause of access to emergency departments. Recurrent syncope may be associated with a transient lock of consciousness. When neurological or cardiological common causes of syncope are excluded, rare causes of syncope, such as solid ...

Is head injury characteristic of arrhythmic syncope?

Journal of Arrhythmia, 2013
Background: Of the syncope types, arrhythmic syncope is the most life threatening and therefore requires proper treatment. However, the clinical predictors of arrhythmic syncope remain unknown.

Commercial Sodium‐Ion Batteries: Understanding Mechanism and Function Using In Operando Neutron Diffraction and X‐Ray Tomography Studies

Advanced Functional Materials, EarlyView.
In operando neutron diffraction reveals the real‐time structural evolution of O3‐type NaxNi1/3Mn1/3Fe1/3O2 in commercial sodium‐ion batteries that is coupled with electrochemical and tomography data. The study establishes a direct link between current‐dependent phase transitions, lattice kinetics, and electrochemical behavior, offering mechanistic ...

Syncope

Journal of Intensive Care Medicine, 2014
Syncope is common representing approximately 3% of ED visits and up to 6% of hospital admissions, with a cost close to 2 billion dollars per year. Diagnostic testing is often poorly sensitive and evaluations commonly lack a standardized approach. A mindful and systematic approach can increase sensitivity and improve diagnostic accuracy.
