A Modified Technique for Converting Retrograde Femoral Artery Access to Antegrade Access With the Assistance of a Long Sheath

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Percutaneous femoral access serves as the cornerstone of endovascular therapy of lower extremity arterial disease. In complex cases, the arterial disease of lower extremity are involve in ipsilateral iliac artery pathology, which conventional treatment strategies typically require multiple punctures or staged procedures.

One Anatomy, Multiple Valve Choices: Interobserver Agreement in Selecting Transcatheter Pulmonary Valve

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
Methodological framework among international observers to understand clinical decision‐making and interobserver agreement in TPVR planning. ABSTRACT Background Transcatheter pulmonary valve replacement (TPVR) requires selecting the optimal device type, size, and position. Variability in anatomical shape may affect procedural planning.

Stereoselective Higher‐Order [10+4]‐ and [10+6] Cycloadditions Between Two Highly Unsaturated and Ambiphilic π‐Addends

open access: yesChemistry – A European Journal, EarlyView.
Aminocatalytically generated isobenzofulvenes and 3‐oxidopyridinium betaines act as ambiphilic reaction partners in orbital‐symmetry‐allowed [10+4] cycloadditions or formally symmetry‐forbidden concerted thermal [10+6] cycloadditions. The reaction furnishes three cycloadducts: one [10+4] cycloadduct and two regioisomeric [10+6] cycloadducts.

Successive Azide and DNA Functionalization for Reversible and Controlled Association of Single‐Wall Carbon Nanotubes

open access: yesChemistry – A European Journal, EarlyView.
A newly synthesized bifunctional azide—diazonium linker allows robust one‐step introduction of azido groups to single‐wall carbon nanotubes. Versatility of the azido groups as reactive handles is demonstrated by further derivatization with 6‐carboxyfluorescein and oligonucleotides.

Decoding Heptazine Architectures: From Molecular Association to Structural Insight

open access: yesChemistry – A European Journal, EarlyView.
A comprehensive study (NMR and theoretical) of three novel heptazine derivatives that self‐assemble into dimers has been conducted, highlighting their versatility as a platform for multifunctional supramolecular and optoelectronic materials. ABSTRACT Heptazine (Hpz) derivatives display remarkable supramolecular organization governed by noncovalent ...
