Influence of Tracheostomy Level on Surgical Management of Pediatric Airway Stenosis

The Laryngoscope, EarlyView.
Tracheostomy location is a critical determinant of surgical complexity and outcomes in pediatric laryngotracheal stenosis. Misplacement may lead to longer tracheal resections, an increased need for stoma relocation, more complex reconstruction, and secondary stenosis. Strategic planning of tracheostomy position can improve surgical outcomes.

Impact of chronic outward force on arterial responses of proximal and distal of long superficial femoral artery stent

BMC Cardiovascular Disorders, 2021
Background Self-expanding nitinol stent (SENS) implantation is commonly oversized in the superficial femoral artery (SFA), and leads to chronic outward force (COF) and in-stent restenosis (ISR).

Mono‐ and Bivalent Poly(iso‐butylene)‐Alanines for Drug‐Delivery of Nimodipine and Triamcinolone Acetonide

Macromolecular Rapid Communications, EarlyView.
Mono‐ and bivalent‐, alanine‐modified poly‐iso‐butylenes, folding into beta‐sheets, were prepared by living carbocationic polymerization and subsequent endgroup modification. These PIB‐conjugates are useful as solid polymers for the drug release of triamcinolone and nimodipine. ABSTRACT Poly‐iso‐butylene (PIB) is a well known biocompatible polymer with

Preclinical Efficacy and Safety Evaluation of a Novel Controlled‐Expansion ePTFE‐Covered TIPS Stent in a Swine Model

Portal Hypertension &Cirrhosis, EarlyView.
This preclinical study evaluated a novel controlled‐expansion expanded polytetrafluoroethylene (ePTFE)‐covered transjugular intrahepatic portosystemic shunt (TIPS) stent in 11 swine, demonstrating 100% technical success, excellent deployability, and durable 6‐month angiographic patency without thrombosis, migration, fracture, or device‐related toxicity.

Effect of stent inflation pressure and post-dilatation on the outcome of coronary artery intervention. A report of more than 90,000 stent implantations. [PDF]

PLoS ONE, 2013
BACKGROUND: Percutaneous coronary intervention (PCI) stent inflation pressure correlates to angiographic lumen improvement and stent expansion but the relation to outcome is not clarified.

Incidence and Risk Factors of In-Stent Restenosis for Symptomatic Intracranial Atherosclerotic Stenosis: A Systematic Review and Meta-Analysis

American Journal of Neuroradiology, 2020
BACKGROUND: In-stent restenosis affects long-term outcome in patients with intracranial atherosclerotic stenosis. PURPOSE: The aim of this meta-analysis was to evaluate the incidence and risk factors of in-stent restenosis.

Proteolysis at the extracellular matrix interface: Molecular architects and regulators in health and disease

The FEBS Journal, EarlyView.
The extracellular matrix (ECM) is a dynamic scaffold that orchestrates tissue architecture and cellular communication. A critical but underexplored interplay between proteases and cluster of differentiation molecules (CD) governs ECM turnover and directs cell fate.

Mechanistic evaluation of long-term in-stent restenosis based on models of tissue damage and growth

Biomechanics and Modeling in Mechanobiology, 2020
Development and application of advanced mechanical models of soft tissues and their growth represent one of the main directions in modern mechanics of solids. Such models are increasingly used to deal with complex biomedical problems.

Far‐infrared irradiation attenuates platelet‐derived growth factor‐stimulated vascular smooth muscle cell migration through protein phosphatase 2A‐mediated Akt inhibition

Photochemistry and Photobiology, EarlyView.
FIR irradiation enhances the physical association between Akt and PP2Ac in VSMCs, independent of the hyperthermal effect of FIR rays. The increased binding between Akt and PP2Ac induced by FIR irradiation facilitates the dephosphorylation of Akt at Ser473.
