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.

Ultrasound methods of imaging atherosclerotic plaque in carotid arteries: examinations using contrast agents

Journal of Ultrasonography, 2020
The primary technique for detecting the presence and monitoring the development of carotid atherosclerotic plaque is ultrasound. The development of ultrasound techniques has made it possible to precisely visualise not only blood flow, but also vessel ...

Picomolar Detection of Tau Protein Using 1D Photonic Crystal Biochips for Alzheimer's Disease Diagnosis

Advanced Sensor Research, EarlyView.
Elevated levels of Tau in cerebrospinal fluids or other body fluids are associated with the progression of Alzheimer's disease. An optical technique, based on a dual label‐free and fluorescence operation mode, is developed to detect Tau protein in both standard running buffer and cerebrospinal fluid.

Extracellular Matrix Targeted MRI Probes

Analysis &Sensing, Volume 3, Issue 1, January 2023., 2023
Gadolinium based MRI probes targeted to ECM components, either proteins or enzymes, hold promise for accurate molecular characterization and staging of fibrotic diseases in vivo. Non‐covalent binding probes (1), reactive probes (2), and enzyme‐responsive probes (3) are discussed.

Error analysis of finite difference/collocation method for the nonlinear coupled parabolic free boundary problem modeling plaque growth in the artery [PDF]

arXiv, 2019
The main target of this paper is to present a new and efficient method to solve a nonlinear free boundary mathematical model of atherosclerosis. This model consists of three parabolics, one elliptic and one ordinary differential equations that are coupled together and describe the growth of a plaque in the artery.

Label free visualization of amyloid plaques in Alzheimer's disease with polarization-sensitive photoacoustic Mueller matrix tomography [PDF]

arXiv, 2022
The formation of amyloid plaques in the cortical and hippocampal brain regions caused by abnormal deposition of extracellular amyloid \b{eta}-protein (A\b{eta}) is a characteristic pathological hallmark of early Alzheimer's disease (AD), while label-free graphic rendering of diseased amyloid plaques in vivo is still a highly challenging task.

Advancing the Identification of Bioactive Molecules and the Construction of a Synergistic Drug Delivery System in Combating Lung Injury

Advanced Science, EarlyView.
Traditional Chinese Medicine (TCM), while holistic and historically esteemed, faces challenges in “miracle cures” due to slow onset, long cycles, and difficulty controlling quality. This study obtains the active ingredients, glabridin (GLA) and puerarin (PUE), from Ge‐Gen Decoction (GGD), developing a safe and effective drug delivery system, GLA‐PUE ...

Virus removal from aqueous environments with polyelectrolyte coatings on a polypropylene fleece

Journal of Applied Polymer Science, Volume 140, Issue 6, February 10, 2023., 2023
We present three methods to immobilize heparin‐mimicking, virus‐binding polymers on filter materials. Linear polyglycerol sulfate is grafted to the surface either via mussel‐inspired coating chemistry, or by using a benzophenone anchor. Herpes simplex virus type 1 and severe acute respiratory virus 2 are efficiently removed from solution upon ...

Iron Deficiency Impairs Dendritic Cell Development and Function, Compromising Host Anti‐Infection Capacity

Advanced Science, EarlyView.
Iron deficiency reduces monocyte dendritic cell progenitor (MDP) numbers by inhibiting migration and proliferation while promoting apoptosis, subsequently reducing downstream common dendritic cell precursors (CDP) and dendritic cell (DC). Impaired DCs enter the lungs via blood circulation, where reduced antigen presentation impairs T‐cell activation ...

Acute perioperative-stress-induced increase of atherosclerotic plaque volume and vulnerability to rupture in apolipoprotein-E-deficient mice is amenable to statin treatment and IL-6 inhibition

Disease Models & Mechanisms, 2015
Myocardial infarction and stroke are frequent after surgical procedures and consume a considerable amount of benefit of surgical therapy. Perioperative stress, induced by surgery, is composed of hemodynamic and inflammatory reactions.
