Transmural versus non-transmural in situ electrical impedance spectrum for healthy, ischemic, and healed myocardium [PDF]

open access: yes, 2004
Electrical properties of myocardial tissue are anisotropic due to the complex structure of the myocardial fiber orientation and the distribution of gap junctions.

Symmetry is the Key to the Design of Reticular Frameworks

open access: yesAdvanced Materials, EarlyView.
Computational prediction of the molecular structure of porous materials, particularly reticular framework materials such as MOFs and COFs, remains a significant challenge. Considering the symmetry of the building blocks that form the desired material, and a similarity score with existing experimentally characterized structures, helps identify promising

Alterations in T1 of normal and reperfused infarcted myocardium after Gd-BOPTA versus GD-DTPA on inversion recovery EPI. [PDF]

open access: yes, 1997
This study tested whether Gd-BOPTA/Dimeg or Gd-DTPA exerts greater relaxation enhancement for blood and reperfused infarcted myocardium. Relaxivity of Gd-BOPTA is increased by weak binding to serum albumin.

Cardiac Organoid Model Inspired Micro‐Robot Smart Patch to Treat Myocardial Infarction

open access: yesAdvanced Materials, Volume 37, Issue 26, July 3, 2025.
The heart organoid model exhibits the acidic microenvironment characteristic of myocardial infarction, which emerges as a pivotal force propelling the movement of micro‐robots. These micro‐robots, administered through microneedles, can penetrate deep into the tissue, effectively delivering therapeutic payloads to facilitate heart repair.
