Studies on Aortic and Aortic Valve Diseases [PDF]

Journal of Clinical & Experimental Cardiology, 2013
Bicuspid aortic valve (BAV) is the most common congenital cardiac malformation, with an estimated incidence of 1%–2% in the general population. Patients with BAV are predisposed to early and frequent stenosis, regurgitation, and endocarditis, often accompanied by aneurysm and dissection.

Alleviation of Aging‐Related Hallmarks in a Mouse Model of Progeria via a Nanoparticle‐Based Artificial Transcription Factor

Advanced Functional Materials, EarlyView.
Oct4‐nanoscript, a biomimetic nanoparticle‐based artificial transcription factor, precisely regulates cellular rejuvenation by activating Oct4 target genes, restoring epigenetic marks, and reducing DNA damage. In a progeria model, it effectively rescued aging‐associated pathologies and extended lifespan.

Segmentation of Aortic Vessel Tree in CT Scans with Deep Fully Convolutional Networks [PDF]

arXiv, 2023
Automatic and accurate segmentation of aortic vessel tree (AVT) in computed tomography (CT) scans is crucial for early detection, diagnosis and prognosis of aortic diseases, such as aneurysms, dissections and stenosis. However, this task remains challenges, due to the complexity of aortic vessel tree and amount of CT angiography data. In this technical

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

Advanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Heart ventricular histology and microvasculature together with aortic histology and elastic lamellar structure: A comparison of a novel dual-purpose to a broiler chicken line [PDF]

, 2019
The use of dual-purpose chickens is a strategy to avoid killing one-day-old male chicks of egg laying lines. Lohmann Dual (LD) is a novel dual-purpose chicken line created by the crossbreeding of layer and broiler lines.

The physical origin of aneurysm growth, dissection, and rupture [PDF]

arXiv, 2023
Rupture of aortic aneurysms is by far the most fatal heart disease, with a mortality rate exceeding 80%. There are no reliable clinical protocols to predict growth, dissection, and rupture because the fundamental physics driving aneurysm progression is unknown.

Bioengineering Strategies for Treating Neointimal Hyperplasia in Peripheral Vasculature: Innovations and Challenges

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
This review highlights emerging bioengineering strategies for treating neointimal hyperplasia in the peripheral vasculature, focusing on approaches that promote re‐endothelialization, modulate smooth muscle cell phenotype, reduce inflammation, mitigate oxidative stress, and optimize biomechanical compliance.

Aortic Valve Disease

, 2007
Calcific disease is the major cause of aortic stenosis. Bicuspid aortic valves lead to aortic stenosis in approximately one half of patients who are born with them. The classic symptoms of valvular aortic stenosis, angina, syncope, and dyspnea represent a major inflection in the natural history of the disease and indicate the need for ...

“Therapies Through Gut:” Targeted Drug Delivery for Non‐Gastrointestinal Diseases by Oral Administration

Advanced Healthcare Materials, EarlyView.
Schematic illustration of the mechanism of targeted delivery of nanoparticles including 1) paracellular, 2) endolysosomal escape, 3) receptor mediated endocytosis, and 4) M cell mediated transport for non‐GI diseases by oral administration such as atherosclerosis, cancer, diabetes, and brain diseases. Abstract Oral drug delivery is a promising approach
