Assembly of Cell‐Seeded 3D Printed Hydrogel Modules with Perfusable Channel Networks

Advanced Functional Materials, EarlyView.
Macroscale assembly was utilized to prepare perfusable tissue constructs from individually 3D printed hydrogel modules with embedded branched channel networks and port arrays for cell seeding. Novel multi‐material bioreactors were fabricated to facilitate the gluing of individual modules and the perfusion culture of assembled modular constructs seeded ...

Atrial septal defect--echocardiographic assessment before and after surgical repair.

Acta Médica Portuguesa, 1979
Twenty-two patients with atrial septal defect (ostium secundum type and sinus venosus) were studied by echocardiography before and after surgery. The sizes of the various heart chambers - right and left ventricles, left atrium and aortic root - and the ...

Predominance of Intrinsic Mechanism of Resting Heart Rate Control and Preserved Baroreflex Sensitivity in Professional Cyclists after Competitive Training. [PDF]

PLoS ONE, 2016
Different season trainings may influence autonomic and non-autonomic cardiac control of heart rate and provokes specific adaptations on heart's structure in athletes. We investigated the influence of transition training (TT) and competitive training (CT)

Pulmonary valvulotomy in a fetus with pulmonary atresia with intact ventricular septum : first experience in Turkey [PDF]

, 2012
The mortality and morbidity of children with pulmonary atresia with intact ventricular septum (PA/IVS) is closely related with right ventricle hypoplasia and its consequent hemodynamics.

Anatomic-electrophysiological correlations concerning the pathways for atrioventricular conduction. [PDF]

, 2001
The remarkable success of radiofrequency ablation in recent decades in curing atrioventricular nodal reentrant tachycardias has intensified efforts to provide a solid theoretical basis for understanding the mechanisms of atrioventricular transmission ...

Application of Foley balloon catheter in palliative surgery for pulmonary atresia with an intact ventricular septem, with additional cases of pulmonary atresia with ventricular septal defect and tetralogy of Fallot

BMC Cardiovascular Disorders, 2023
Background Pulmonary atresia and tetralogy of Fallot can require palliative surgery in the neonatal period due to severe hypoxia; however, limitations of established techniques include high failure rate and need for cardiopulmonary bypass.

Automatic segmentation of the left ventricle cavity and myocardium in MRI data [PDF]

, 2006
A novel approach for the automatic segmentation has been developed to extract the epi-cardium and endo-cardium boundaries of the left ventricle (lv) of the heart. The developed segmentation scheme takes multi-slice and multi-phase magnetic resonance (MR)

Respiratory Organ‐on‐a‐Chip for Disease Modeling: From Architecture to Functional Integration

Advanced Healthcare Materials, EarlyView.
Respiratory organ‐on‐a‐chip (ROC) models capture key mechanical and cellular cues of the human respiratory system, enabling quantitative dissection of disease mechanisms. This review links ROC architectures to disease modeling, functional integration, and commercialization, and proposes a decision framework that aligns model complexity with mechanistic
