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.

Miniaturized Devices for On‐the‐Spot Generation of Small‐Diameter Vascular Grafts

Advanced Materials Technologies, EarlyView.
An intracorporeal extrusion device is developed for on‐the‐spot generation of vascular grafts with tunable diameters spanning from 1 to 6 mm. The device uses biomimetic polymers and light, to promptly obtaining biocompatible and high‐burst pressure‐resistant grafts.

Aortic and arterial mechanics [PDF]

Cardiovascular Mechanics, 2018, 2019
Knowledge of the mechanical properties of the aorta is essential as important concerns regarding the treatment of aortic pathologies, such as atherosclerosis, aneurysms and dissections, are fundamentally mechanobiological. A comprehensive review is presented in the current chapter. As the function of arteries is to carry blood to the peripheral organs,

Numerical modelling of a peripheral arterial stenosis using dimensionally reduced models and kernel methods [PDF]

, 2018
In this work, we consider two kinds of model reduction techniques to simulate blood flow through the largest systemic arteries, where a stenosis is located in a peripheral artery i.e. in an artery that is located far away from the heart. For our simulations we place the stenosis in one of the tibial arteries belonging to the right lower leg (right post

Targeting Decidual CD16+ Immune Cells with Exosome‐Based Glucocorticoid Nanoparticles for Miscarriage

Advanced Science, EarlyView.
Exosome‐based nanoparticles (GC‐Exo‐CD16Ab) are designed to deliver glucocorticoids (GC) specifically to decidual CD16+ NK cells and macrophages. This targeted delivery effectively suppresses the cytotoxicity of decidual NK cells, inhibits M1 macrophage polarization, and modulates the decidual microenvironment.

Application of signal processing techniques in the assessment of clinical risks in preterm infants [PDF]

arXiv, 2014
Preterm infants with very low birth weight suffer from a high risk of intra-ventricular hemorrhage(IVH) and other serious diseases. To improve the clinical risk assessment of preterm infants and develop potential clinically makers for the adverse outcome, the first part of the paper develops the frequency spectral analysis on the non-invasively ...

Macrophage HM13/SPP Enhances Foamy Macrophage Formation and Atherogenesis

Advanced Science, EarlyView.
Previous research suggests that AIP may prevent atherogenic foamy macrophage formation. This study reveals that AIP, via its chaperone interaction with AHR, inhibits p38‐c‐JUN‐mediated transactivation of HM13, which encodes the ERAD protease HM13/SPP. HM13/SPP promotes foamy macrophage formation in addition to atherogenesis and plaque foamy macrophage ...

Depletion of Hepatic SREBP2 Protects Against Hypercholesterolemia and Atherosclerosis through the ANGPTL3‐LPL Axis

Advanced Science, EarlyView.
This study reveals a novel crosstalk between hepatic SREBP2‐mediated cholesterol biosynthesis pathway and peripheral lipoprotein lipase‐mediated lipolysis pathway in the regulation of systemic lipid metabolism. Notably, the lipid‐lowering effects of SREBP2 inhibition are independent of a functional LDL receptor, highlighting the potential of acute ...
