Vascularized and Perfusable Human Heart‐on‐a‐Chip Model Recapitulates Aspects of Myocardial Ischemia and Enables Analysis of Nanomedicine Delivery

Advanced Materials, EarlyView.
This novel 3D human ischemic heart‐on‐a‐chip, with perfusable vasculature directly interfaced with myocardial tissue, replicates key aspects of ischemic heart injury. It also demonstrates the targeted delivery and therapeutic efficacy of cardiac homing peptide‐conjugated liposomes, validating the platform for drug and nanomedicine screening in ...

Bioxolography Using Diphenyliodonium Chloride and N‐Vinylpyrrolidone Enables Rapid High‐Resolution Volumetric 3D Printing of Spatially Encoded Living Matter

Advanced Materials, EarlyView.
Bioxolography, a novel volumetric 3D‐bioprinting technique, enables rapid and high‐resolution fabrication of >1 cm3 engineered living materials. A newly developed three‐component photoinitiator system significantly enhances the photoreactivity of gelatin methacryloyl‐based bioresins, allowing for precise xolographic bioprinting.

Formation of large coronary arteries by cardiac progenitor cells

Proceedings of the National Academy of Sciences of the United States of America, 2008
Coronary artery disease is the most common cause of cardiac failure in the Western world, and to date there is no alternative to bypass surgery for severe coronary atherosclerosis.

Coronary artery surgery.

Acta medica portuguesa, 1980
CIRURGIA DAS CORONÁRIAS Nenhum campo da cirurgia cresceu tão rapidamente como o da revascularização coronária directa. De facto, desde a introdução da portagem aorto-coronária por Favaloro e Johnson, este processo foi adoptado nos E.U.A. e o número destas operações tem aumentado anualmente.

Biomimetic Cell Membrane‐Coated Scaffolds for Enhanced Tissue Regeneration

Advanced Materials, EarlyView.
This review examines the development and use of cell membrane‐coated scaffolds in tissue engineering. Bioinspired phospholipid and glycocalyx coatings enhance anti‐fouling, anti‐thrombogenic, and selective molecular recognition properties. Native cell membrane coatings further support cell‐specific interactions, immune modulation, and reduced bacterial

Stimuli‐Responsive Materials for Biomedical Applications

Advanced Materials, EarlyView.
Stimulus‐responsive materials (SRMs) hold great promise for use in a wide range of biomedical applications. This review covers four stimulus modalities, namely, electrical, optical, magnetic, and ultrasound, and their associated SRMs. It provides a summary of the materials in each modality, their development, and current research perspectives.

Coronary Artery Diameter is Inversely Associated with the Severity of Coronary Lesions in Patients Undergoing Coronary Angiography

Cellular Physiology and Biochemistry, 2017
Background: The diameters of the coronary arteries have been suggested to be a potential predictor of coronary artery disease (CAD). However, whether the diameters of the coronary arteries are associated with the coronary lesion severity on angiography ...

Flow Analysis in Pathological Microvascular Models by Ultrasound Localization Microscopy

Advanced Materials Technologies, EarlyView.
This study presents a new platform combining ultrasound localization microscopy with biomimetic gelatin phantoms to analyze flow dynamics in small vessels with narrowing or obstructions. Using microbubble tracking, the method enables high‐resolution velocity mapping in 100–500 µm channels, revealing flow changes in pathological microvascular conditions

Pulmonary artery from the left main coronary artery

Annals of Pediatric Cardiology, 2019
The usual sources of pulmonary blood flow in pulmonary atresia (PA) with(VSD) are patent ductus arteriosus and aortopulmonary collaterals. However, rarely fistulous collaterals may also arise from the coronary arteries which usually open into the main ...
