Comparison of aortic stiffness and hypertension in repaired coarctation patients with a bicuspid versus a tricuspid aortic valve

Journal of Cardiovascular Magnetic Resonance, 2023
Background Coarctation of the aorta (COA) is associated with reduced aortic distensibility and systemic hypertension (HTN). 60–85% of COA patients have a bicuspid aortic valve (BAV). It is not known if the presence of a BAV accentuates the aortopathy and

Opportunities for 2D‐Material‐Based Multifunctional Devices and Systems in Bioinspired Neural Networks

Small, EarlyView.
Bio‐inspired computing offers a route to highly energy‐efficient artificial intelligence. The unique physical properties of two‐dimensional (2D) materials can further enhance such computing approaches. This perspective highlights recent developments in 2D materials‐based neuromorphic devices and discusses future opportunities for integrating such novel

Bridging the Effects of Noncontact Temperature Sensing and Cellular Biofunctionality in Nanosized Dysprosium(III)‐Doped Fluorapatite

Small, EarlyView.
Multifunctional dysprosium(III) ion–doped fluorapatite nanomaterials combine bioactivity with photoluminescent temperature sensing. The biological studies reveal interactions with progenitor cells, highlighting potential applications in regenerative medicine and tissue engineering, while temperature‐dependent emission of Dy³⁺ ions enables reliable ...

New Hybrid Nanocomposite Films for Optical Diagnostics and Optical Temperature Sensing: Synergy Among α‐Synuclein, Gold and Upconverting Nanoparticles

Small, EarlyView.
Gold and upconverting nanoparticles coated with alpha‐synuclein were exploited to produce a quasi‐monolayer hybrid film. The film was then characterized, and its behaviour as a primary optical nano‐thermometer was studied. The film was also used in a proof‐of‐concept study of image‐based optical nanothermometry exploiting a home‐built up‐conversion ...

Impact of Valve Morphology on the Prevalence of Coronary Artery Disease: A Systematic Review and Meta‐Analysis

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundLiterature studies suggested a lower prevalence of coronary artery disease (CAD) in bicuspid aortic valve (BAV) than in tricuspid aortic valve (TAV) patients. However, this finding has been challenged.

Matrix Metalloproteinase-2 Isoforms Differ within the Aortic Wall of Ascending Aortic Aneurysms Associated with Bicuspid Aortic Valve

Cardiology Research and Practice, 2020
The pathogenesis of ascending thoracic aortic aneurysm (aTAA) is thought to differ between patients with bicuspid aortic valve (BAV) and tricuspid aortic valve (TAV), and one of the causes is different hemodynamics. Influenced by hemodynamics, the tissue

Degenerated Transcatheter Aortic Valve Replacement: Investigation and Management Options. [PDF]

With the expansion of transcatheter aortic valve replacement (TAVR) to younger and lower-surgical-risk patients, many younger and less comorbid patients will be treated with TAVR and are expected to have a life expectancy that will exceed the durability ...

Quantizing DNA Metallization for Site‐Defined Growth of Single Quantum Emitters

Small Structures, EarlyView.
Predictive design rules guide DNA origami‐templated synthesis of atomically precise silver nanoclusters. Controlled nucleation yields single emitters with nanometer registration and reproducible fluorescence signatures, paving the way toward programable quantum photonic architectures and nanoscale device integration.
