Efficacy and Safety of Drug-Eluting Stents in the Real World: 8-Year Follow-Up

Arquivos Brasileiros de Cardiologia, 2014
Background: Drug-eluting stents have been used in daily practice since 2002, with the clear advantages of reducing the risk of target vessel revascularization and an impressive reduction in restenosis rate by 50%-70%.

Deformation Mechanics of Self-expanding Venous Stents: Modelling and Experiments [PDF]

arXiv, 2021
Deformation properties of venous stents based on braided design, chevron design, Z design, and diamond design are compared using in vitro experiments coupled with analytical and finite element modelling. Their suitability for deployment in different clinical contexts is assessed based on their deformation characteristics. Self-expanding stainless steel

Functional Polymer Nanocomposites by Gas Aggregation Cluster Source and Initiated Chemical Vapor Deposition

Advanced Materials Technologies, EarlyView.
In this work, a gas aggregation cluster source and an initiated chemical vapor deposition are combined in a single vacuum reactor. With this setup polymer thin films can be combined with functional nanoparticles. As a proof‐of‐concept PTFE is combined with silver nanoparticles and tested in antibacterial, antiviral, and anticancer applications ...

Very Late Pathological Responses to Cobalt–Chromium Everolimus‐Eluting, Stainless Steel Sirolimus‐Eluting, and Cobalt–Chromium Bare Metal Stents in Humans

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundThe “very late” clinical outcomes for durable polymer drug‐eluting stents and bare metal stents (BMSs) have been shown to be dissimilar in clinical studies.

The future of drug eluting stents [PDF]

Heart, 2006
In-stent restenosis (ISR) is the major drawback of percutaneous coronary interventions, occurring in 10-40% of patients. Drug eluting stents (DES) are successful in a large majority of patients in preventing restenosis for the first year after implantation.

Artesunate Inhibits Neointimal Hyperplasia by Promoting IRF4 Associated Macrophage Polarization

Advanced Science, EarlyView.
This study shows that macrophage interferon regulatory factor 4 (IRF4) improved arterial injury‐induced neointimal hyperplasia by promoting of M2 polarization via up‐regulating krüppel‐like factor 4 (KLF4) in rodent and nonhuman primate models. Notably, artesunate is identified as a potent inducer of IRF4 in macrophages, and proposed as a promising ...

Direct Targeting of the mTOR (Mammalian Target of Rapamycin) Kinase Improves Endothelial Permeability in Drug-Eluting Stents—Brief Report

Arteriosclerosis, Thrombosis and Vascular Biology, 2018
Objective— Drug-eluting stents eluting canonical mTOR (mammalian target of rapamycin) inhibitors are widely used to treat coronary artery disease but accelerate the development of atherosclerosis within the stent (neoatherosclerosis)—a leading cause of ...

Silicon Enhances Functional Mitochondrial Transfer to Improve Neurovascularization in Diabetic Bone Regeneration

Advanced Science, EarlyView.
These findings reveal that silicon exerts strong protective effects in diabetic bone defect models by selectively promoting Drp1‐Mff activity. Silicon facilitates precise regulation of mitochondrial dynamics to enable functional mitochondrial transfer.
