Endovascular treatment of intracranial internal carotid artery bifurcation region aneurysms

Frontiers in Neurology
Intracranial internal carotid artery (ICA) bifurcation region aneurysms are uncommon. When treatment is necessary for ICA, endovascular treatment (EVT) can be a useful option. Due to the complexity of these aneurysms and the variability of EVT techniques,

Halo orbits around the collinear points of the restricted three-body problem

, 2015
We perform an analytical study of the bifurcation of the halo orbits around the collinear points $L_1$, $L_2$, $L_3$ for the circular, spatial, restricted three--body problem.

Effect of 2D and 3D ECM and Biomechanical Cues on Human iPSC‐Derived Liver Progenitor Cell Differentiation

Advanced Healthcare Materials, EarlyView.
An engineered microtissue model is developed and optimized to investigate human liver development. Extracellular matrix composition and mechanical forces are tuned using high‐throughput assays. Human induced pluripotent stem cells serve as the cellular source, enabling the observation of de novo patterned differentiation.

A Patient‐Specific 3D Printed Carotid Artery Model Integrating Vascular Structure, Flow, and Endothelium Responses

Advanced Healthcare Materials, EarlyView.
This study introduces the first miniaturized, patient‐specific carotid artery model created via 3D printing using GelMA with embedded vascular cells. Combining CFD, PIV, and flow perfusion, the model replicates anatomically dependent hemodynamics and cellular responses.

A Sacrificial 3D Printed Vessel‐on‐Chip Demonstrates a Versatile Approach to Model Granulation Tissue

Advanced Healthcare Materials, EarlyView.
A novel method that combines 3D printing and organ‐on‐chip technology enables the creation of hollow channels lined with endothelial cells through a fibroblast‐populated connective tissue matrix. The model supports stable metabolic culture conditions, angiogenic sprouting, and immune cell migration, thereby demonstrating an easy and versatile method to
