Progress and Application of Multifunctional Hydrogel in Radioactive Skin Injury

Advanced Materials Interfaces, EarlyView.
This review examines healing challenges in radiation‐wound injuries, where ionizing radiation impairs immune and tissue repair processes. Hydrogels, with their biocompatibility, antimicrobial properties, and drug delivery capabilities, present a transformative solution. It compares hydrogel efficacy in radiation‐induced versus common wounds, highlights

Combined Anatomical Anomalies of Direct Aortic Arch Origins of the Left Internal Carotid, Left External Carotid, and Left Vertebral Arteries: A Case Report

Journal of the Korean Society of Radiology, 2023
Various branch anomalies of the aortic arch have been reported, but cases with separate origins of the internal and external carotid arteries with combined direct aortic arch origin of the left vertebral artery are extremely rare.

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 ...

Visualizing Carotid Blood Flow Simulations for Stroke Prevention [PDF]

arXiv, 2021
In this work, we investigate how concepts from medical flow visualization can be applied to enhance stroke prevention diagnostics. Our focus lies on carotid stenoses, i.e., local narrowings of the major brain-supplying arteries, which are a frequent cause of stroke.

The contribution of the external carotid artery to cerebral perfusion in carotid disease [PDF]

Journal of Vascular Surgery, 2000
In the presence of carotid occlusion, the external carotid artery (ECA) becomes an important source of cerebral blood flow, especially if the circle of Willis is incomplete. The contribution of the ECA to hemispheric blood flow in patients with severe ipsilateral carotid stenosis has never been previously investigated.One hundred eight patients were ...

Computational Fluid Dynamic Simulations In a Model of a Carotid Bifurcation Under Steady Flow Conditions [PDF]

arXiv, 2020
Strokes are still one of the leading causes for death after heart diseases and cancer in all over the world. Most strokes happen because an artery that carries blood uphill from the heart to the head gets clogged. Most of the time, as with heart attacks, the problem is atherosclerosis, hardening of the arteries, calcified buildup of fatty deposits on ...

Label Propagation for 3D Carotid Vessel Wall Segmentation and Atherosclerosis Diagnosis [PDF]

arXiv, 2022
Carotid vessel wall segmentation is a crucial yet challenging task in the computer-aided diagnosis of atherosclerosis. Although numerous deep learning models have achieved remarkable success in many medical image segmentation tasks, accurate segmentation of carotid vessel wall on magnetic resonance (MR) images remains challenging, due to limited ...

Flow Velocities in the External Carotid Artery Following Carotid Revascularization [PDF]

European Journal of Vascular and Endovascular Surgery, 2013
To study the changes in peak systolic velocities of the ipsilateral external carotid artery (ECA) following carotid revascularization.All patients randomized to carotid artery stenting (CAS) or carotid endarterectomy (CEA) in the International Carotid Stenting Study (ICSS; ISRCTN25337470) in our center were included. Peak systolic velocities (PSV) were
