Microfabricated Anisotropic Myobundles for the Scalable Production of Cardiac Tissue Grafts

open access: yesAdvanced Functional Materials, EarlyView.
Controlling the anisotropy of cardiac tissue remains an outstanding challenge in the field of cardiac tissue engineering. Here, we introduce an approach to generate anisotropic cardiac myobundles using cell‐adhesive, synthetic, electrospun fibers and stem cell‐derived cardiac fibroblasts.

On the Einthoven Triangle: A Critical Analysis of the Single Rotating Dipole Hypothesis

open access: yesSensors, 2018
Since its inception, electrocardiography has been based on the simplifying hypothesis that cardinal limb leads form an equilateral triangle of which, at the center/centroid, the electrical equivalent of the cardiac activity rotates during the cardiac ...

Cardiac Cycle Estimation for BOLD-fMRI [PDF]

open access: yes, 2018
Previous studies [1, 2] have shown that slow variations in the cardiac cycle are coupled with signal changes in the blood-oxygen level dependent (BOLD) contrast. The detection of neurophysiological hemodynamic changes, driven by neuronal activity, is hampered by such physiological noise.

Pkm2 regulates cardiomyocyte cell cycle and promotes cardiac regeneration

open access: yes, 2020
Background: The adult mammalian heart has limited regenerative capacity, mostly attributable to postnatal cardiomyocyte cell cycle arrest. In the last 2 decades, numerous studies have explored cardiomyocyte cell cycle regulatory mechanisms to enhance ...
