Intramural resistivity of cardiac tissue

Medical and Biological Engineering and Computing, 1979
The macroscopic resistivity of canine ventricular tissue has been measuredin vivo. Using a tetrapolar intramural electrode, values have been obtained for transmural resistivity as a function of depth, phase of the cardiac cycle and of the frequency of the applied current. The time course of resistivity owing to induced local ischaemia has been recorded.

Cardiac Adipose Tissue Contributes to Cardiac Repair: a Review

Stem Cell Reviews and Reports, 2021
Cardiac adipose tissue is a metabolically active adipose tissue in close proximity to heart. Recent studies emphasized the benefits of cardiac adipose tissue in heart remodeling, such as reducing infarction size, enhancing neovascularization and regulating immune response, through a series of cellular mechanisms. In the present manuscript, we provide a

Cardiac Ultrasonic Tissue Characterization

Hospital Practice, 1982
This new variation on an old technique can actually define the physical state of a tissue--not merely visualize its size and motion. Clinical use awaits technologic refinements, but potential applications include noninvasive detection of amyloid protein, of myofibrillar disorientation characteristic of idiopathic hypertrophic subaortic stenosis, and of

Hydrogels for cardiac tissue regeneration

Bio-Medical Materials and Engineering, 2008
Our research is focused on the design of engineered biomaterials that can harness natural cellular and molecular healing pathways to enhance functional tissue regeneration. Two important considerations for tissue regeneration are induction and remodeling.

On Materials for Cardiac Tissue Engineering

Advanced Healthcare Materials, 2016
In this essay the authors argue that chamber pressure dominates the biomechanics of the contraction cycle of the heart, while tissue stiffness dominates the relaxation cycle. This appears to be an under-recognized challenge in cardiac tissue engineering.

Bioreactors for Cardiac Tissue Engineering

Advanced Healthcare Materials, 2018
AbstractThe advances in biotechnology, biomechanics, and biomaterials can be used to develop organ models that aim to accurately emulate their natural counterparts. Heart disease, one of the leading causes of death in modern society, has attracted particular attention in the field of tissue engineering.

Pacemaker Mechanisms in Cardiac Tissue

Annual Review of Physiology, 1993
The heartbeat is a sign of life, and not surprisingly it has attracted much interest and curiosity since the early stages of scientific investigation. Even Leonardo da Vinci, in his anatomical studies, realized that rhythmic, restless activity was an intrinsic property of cardiac muscle (92), "As to the heart: it moves itself, and doth never stop ...

Cardiac muscle tissue engineering

IEEE Engineering in Medicine and Biology Magazine, 2003
Cell-based therapy has emerged as a novel approach for replacing heart muscle, which is known not to regenerate after injury such as that caused by infarction or reconstructive surgery. Two types of cell-based therapies have been employed: injection of isolated cells or the implantation of in-vitro-grown cardiac muscle tissue equivalents In the first ...

Strategies in cardiac tissue engineering

ANZ Journal of Surgery, 2010
AbstractIn heart failure, post‐myocardial infarction and some congenital cardiac anomalies, organ transplantation is the only effective cure. Shortage of organ donors and complications of orthotopic heart transplant remain major challenges to the modern field of transplantation.

Whole Cardiac Tissue Bioscaffolds

2018
Bioscaffolds serve as structures for cells in building complex tissues and full organs including heart. Decellularizing cardiac tissue results in cell-free extracellular matrix (ECM) that can be used as a cardiac tissue bioscaffold. The field of whole-heart tissue engineering has been revolutionized since the 2008 publication of the first perfusion ...
