Volumetric 3D Printing and Melt‐Electrowriting to Fabricate Implantable Reinforced Cardiac Tissue Patches

Advanced Materials, EarlyView.
This study presents an implantable reinforced cardiac patch (RCPatch) combining volumetrically 3D‐printed metamaterials with melt‐electrowritten (MEW) meshes. The design integrates tunable stiff polymer structures with soft, cell‐laden hydrogels. The RCPatch withstands suturing, intraventricular pressure, and cardiac contraction in a large animal ...

Sacrificial Biofabrication for Vascularization: Concept, Materials, Technologies, and Applications

Advanced Materials, EarlyView.
Vasculature is indispensable for tissue viability in regenerative medicine. The sacrificial biofabrication enables precise fabrication of vascular channels by using temporary templates that are subsequently removed. This review defines the concept and delves into sacrificial materials, surrounding materials, fabrication technologies, and biomedical ...

Urine high sensitive Troponin I measuring in patients with hypertension

, 2017
High sensitive troponin I (hsTnI) is one of the markers of cardiac damage. Its values increase two to three hours after a heart attack and remain elevated for days. Recent studies have shown that kidneys are the main organ of elimination of troponin from

High-sensitivity cardiac troponin T and copeptin assays to improve diagnostic accuracy of exercise stress test in patients with suspected coronary artery disease [PDF]

, 2014
Background: The average diagnostic sensitivity of exercise stress tests (ESTs) is lower than that of other non-invasive cardiac stress tests. The aim of the study was to examine whether high-sensitivity cardiac troponin T (hs-cTnT) or copeptin ...

The Bionic Interface: Considering the Material Mediated Electrical Stimulation of Stem Cells

Advanced Materials, EarlyView.
Electrical stimulation directs stem cell fate in tissue engineering. Cellular responses are influenced by membrane properties, intrinsic cell state, material charge‐transport characteristics, and the applied electrical signal. Additionally, a material’s ability to inject, store, and redistribute charge further modulates these responses.

Cardiac troponin i in acute pericarditis [PDF]

Journal of the American College of Cardiology, 2003
This study was designed to investigate the prognostic value of cardiac troponin I (cTnI) in viral or idiopathic pericarditis.Idiopathic acute pericarditis has been recently reported as a possible cause of nonischemic release of cTnI. The prognostic value of this observation remains unknown.We enrolled 118 consecutive cases (age 49.2 +/- 18.4 years; 61 ...

One‐Step Coordinated Multi‐Kinetic 4D Printing of Human Vascularized Cardiac Tissues with Selective Fast‐Shrinking Capillaries

Advanced Materials, EarlyView.
This study presents a novel 4D bioprinting technique for fabricating cardiac tissues with complex microvasculature. Unlike traditional 3D printing, it enables capillary‐scale structure formation via selective post‐printing shrinkage. This approach overcomes resolution limits of printing cell‐laden hydrogels, allowing the creation of functional ...

Can troponin-I be used as an independent predictor of cardiac dysfunction after supraventricular tachycardia in children with structural normal heart? [PDF]

Vojnosanitetski Pregled, 2019
Introduction. Elevated cardiac troponin gives excellent accuracy in the identification of myocardial damage in children, but it can also be elevated in a series of other diseases. Case report.
