Nanostructured 316L Stainless Steel Stent Surfaces Improve Corrosion Resistance, and Enhance Endothelization and Hemocompatibility

Advanced Materials Interfaces, EarlyView.
This study investigates the impact of nanostructured surface modification on corrosion resistance, HUVEC functions, and platelet interactions of 316L SS for cardiovascular stents. Nanostructured surfaces enhanced HUVEC proliferation, migration, and angiogenesis‐related gene expression while reducing platelet adhesion and hemolysis.

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

Advanced Materials Technologies, Volume 10, Issue 9, May 6, 2025.
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 ...

Restenosis pathophysiological mechanisms and genetic markers after percutaneous coronary interventions

Кардиоваскулярная терапия и профилактика, 2007
Coronary restenosis remains the main problem for effectiveness of percutaneous transluminal coronary angioplasty (PCA) and coronary stenting (CS). The aim of this review is to analyze pathogenetic mechanisms of coronary restenosis after PCA and CS, as ...

Excessive MYC Orchestrates Macrophages induced Chromatin Remodeling to Sustain Micropapillary‐Patterned Malignancy in Lung Adenocarcinoma

Advanced Science, Volume 12, Issue 12, March 27, 2025.
Song et al. integrates an evaluating system to characterize malignancy of micropapillary (MP)‐pattern lung adenocarcinoma in vivo or in vitro. They have discovered that intrinsic MYC redundancy expression combined with extrinsic M2‐like macrophage jointly mediate MP‐pattern malignancy.

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 ...

Rounded notch method of femoral endarterectomy offers mechanical advantages in finite element models [PDF]

arXiv, 2023
Objective: Use of a vascular punch to produce circular heel and toe arteriotomies for femoral endarterectomy with patch angioplasty is a novel technique. This study investigated the plausibility of this approach and the mechanical advantages of the technique using finite element models.

Caracterización de la restenosis de stents coronarios convencionales y liberadores de medicamentos en pacientes incluidos en el registro DRug Eluting STent (DREST)

Revista Colombiana de Cardiología, 2012
los stents convencionales presentan tasas de restenosis intrastent entre 10% y 60%, mientras los stents liberadores de fármacos alcanzan el 10%. Para Latinoamérica, no hay reportes de restenosis intrastent en comparación con los stents convencionales y ...

Endothelial TRIM35‐Regulated MMP10 Release Exacerbates Calcification of Vascular Grafts

Advanced Science, Volume 12, Issue 11, March 20, 2025.
Arterial bypass graft is routinely used for the patients with coronary artery infarction, but is limited by progressive vascular restenosis and occlusion occurs, in which vascular calcification is a key issue. Endothelial TRIM35 can protect the isograft vascular from calcification by activating RelB ubiquitination that inhibits MMP10 secretion ...

The candy wrapper problem -- a temporal multiscale approach for pde/pde systems [PDF]

arXiv, 2020
We describe a temporal multiscale approach for the simulation of long-term processes with short-term influences involving partial differential equations. The specific problem under consideration is a growth process in blood vessels. The \emph{Candy Wrapper Process} describes a restenosis in a vessel that has previously be widened by inserting a stent ...
