Plaque Morphology‐Dependent Regression of Tandem Coronary Plaques Under Intensive Lipid‐Lowering Therapy

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT We report a 54‐year‐old woman with stable angina who exhibited heterogeneous responses of tandem left anterior descending artery (LAD) plaques to intensive lipid‐lowering therapy. Coronary CT angiography performed at another hospital suggested diffuse disease, and she presented to our clinic for a second opinion.

N-Alkylated dinitrones from isosorbide as cross-linkers for unsaturated bio-based polyesters

open access: yesBeilstein Journal of Organic Chemistry, 2014
Isosorbide was esterified with acryloyl chloride and crotonic acid yielding isosorbide diacrylate (9a) and isosorbide dicrotonate (9b), which were reacted with benzaldehyde oxime in the presence of zinc(II) iodide and boron triflouride etherate as ...

Ultrasound–triggered tumor‐selective nitric oxide release enhances tumor penetration of antibody–conjugated nanomedicine

open access: yesInterdisciplinary Medicine, EarlyView.
Ultrasound‐triggered nitric oxide release from S‐nitrosated hyaluronic acid (HA‐SNO) induces tumor vasodilation and disrupts the vascular barrier, potently enhancing the intratumoral penetration of antibody‐conjugated nanomedicines. Abstract The tumor vascular barrier restricts the penetration of antibody‐conjugated nanomedicine, severely limiting its ...

Isomannide-containing poly(butylene 2,5-furandicarboxylate) copolyesters via ring opening polymerization [PDF]

open access: yes, 2018
Cyclic oligomers of isomannide 2,5-furandicarboxylate were synthesized using the high dilution condensation method. A mixture of dimer, trimer, and tetramer species largely enriched in dimer was obtained.

Bio‐Based Polyurethanes: Mechanical Performance, Structure–Property Relationships, and Future Directions

open access: yesJournal of Polymer Science, EarlyView.
This review examines bio‐based polyurethanes from renewable feedstocks, focusing on structure‐property relationships governing mechanical performance. It analyzes reinforcement strategies, benchmarks against petrochemical counterparts, and explores future directions, including non‐isocyanate routes and circular economy integration for sustainable high ...

The Combined Effect of Gas Phase and Condensed Phase Mechanisms in Flame Retardancy of Polybutylene Succinate

open access: yesJournal of Vinyl and Additive Technology, EarlyView.
A combination of DOPO and APP flame‐retardants results in a V‐0 UL 94 rating. ABSTRACT In this study, we addressed the challenge of eliminating, during combustion, the flaming dripping behavior of polybutylene succinate flame retarded with ammonium polyphosphate, a key barrier to achieving a V‐0 rating in the UL 94 flammability test without excessive ...

Isohexide and sorbitol-derived, enzymatically synthesized renewable polyesters with enhanced Tg [PDF]

open access: yes, 2016
Sugar-based polyesters derived from sorbitol and isohexides were obtained via solvent-free enzymatic catalysis. Pendant hydroxyl groups, coming from the sorbitol units, were present along the polyester backbone, whereas the two isohexides, namely ...
