Aortic Dissection With Pseudoaneurysm Formation Masquerading as Pulmonary Embolism After Transcatheter Aortic Valve Replacement

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Transcatheter aortic valve replacement (TAVR) is a commonly performed procedure for the treatment of severe aortic stenosis. While it is generally considered a low‐risk procedure, one of the rare potentially life‐threatening complications includes aortic dissection.

Intracellular Catalytic Photooxygenation of α‐Synuclein Amyloid

ChemistryEurope, EarlyView.
Amyloid‐selective catalytic photooxygenation reduces amyloid toxicity, aggregation tendencies, and seeding activities. Achieving therapeutic catalysis for intracellular amyloids is challenging due to conflicting oxygenation and reductive cellular environments.

Mn2+ Bispidine Complexes as Potential Magnetic Resonance Imaging Agents : Noncoordinating Peripheral Functional Groups Affect Structural, Kinetic, and Relaxation Properties

ChemistryEurope, EarlyView.
In the family of Mn2+ complexes formed with pentadentate bispidine chelates, functional groups that do not interfere with metal coordination can play a significant role in enhancing kinetic inertness and proton relaxation efficacy. Mn2+ bispidine complexes combine unprecedented kinetic inertness with high relaxivity and are under scrutiny as potential ...

Optimization of CEST MRI Reporter Protein Design Using Cation‐Pi Networks

Chemistry – A European Journal, EarlyView.
A novel engineering approach can produce reporter proteins for cell and viral therapy tracking with unique magnetic resonance imaging (MRI) signatures, detectable with chemical exchange saturation transfer (CEST). We discover how cation‐π interactions between amino acid groups can help us fine‐tune magnetic resonance properties for noninvasive ...
