Proximity mapping of troponin T and troponin I in cardiac troponin using molecular dynamics simulations [PDF]

Biophysical Journal, 2009
The intersite distances from cTnT residues 240, 276, and 288 to cTnI N-terminal residues 5, 17, 27, 40, and to the cTnI C-terminal residues 131, 145, 152, 160, and 167 in reconstituted cTn were determined in the presence of Mg2+ and Mg2+ plus Ca2+ using FRET.

Vascularized and Perfusable Human Heart‐on‐a‐Chip Model Recapitulates Aspects of Myocardial Ischemia and Enables Analysis of Nanomedicine Delivery

Advanced Materials, EarlyView.
This novel 3D human ischemic heart‐on‐a‐chip, with perfusable vasculature directly interfaced with myocardial tissue, replicates key aspects of ischemic heart injury. It also demonstrates the targeted delivery and therapeutic efficacy of cardiac homing peptide‐conjugated liposomes, validating the platform for drug and nanomedicine screening in ...

Cardiac biomarkers for screening and prognostication of cardiac dysfunction in critically ill patients

ESC Heart Failure
Aims This study aimed to assess the use of high‐sensitivity troponin T (hsTNT) and N‐terminal pro‐brain natriuretic peptide (NT‐proBNP) in screening for cardiac dysfunction [left ventricular (LV) systolic or diastolic dysfunction or right ventricular (RV)

Engineered Plasmonic and Fluorescent Nanomaterials for Biosensing, Motion, Imaging, and Therapeutic Applications

Advanced Materials, EarlyView.
A schematic illustration of how noble metals can be used to create nanoparticles (NPs) or nanoclusters (NCs). Noble metal NPs, due to their plasmonic properties, enable photothermal therapy and surface‐enhanced Raman scattering (SERS). In contrast, NCs, which lack a plasmonic resonance band, exhibit fluorescence, making them ideal for bioimaging ...

Immune Checkpoint Inhibitor-Related Adverse Cardiovascular Events in Patients With Lung Cancer

JACC. CardioOncology, 2019
Objectives: The purpose of this study was to evaluate whether immune checkpoint inhibitors (ICIs) are associated with an increased risk of major adverse cardiovascular events (MACE) compared with non-ICI therapies in patients with lung cancer. Background:

Diagnostic Thresholds for Pre–Diabetes Mellitus and Diabetes Mellitus and Subclinical Cardiac Disease in the General Population: Data From the ACE 1950 Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background Diabetes mellitus (DM) is associated with left ventricular remodeling and incident heart failure, but the association between glycated hemoglobin A1c (HbA1c) and subclinical cardiac disease is not established.

Dephosphorylation specificities of protein phosphatase for cardiac troponin I, troponin T, and sites within troponin T [PDF]

International Journal of Biological Sciences, 2006
Protein dephosphorylation by protein phosphatase 1 (PP1), acting in concert with protein kinase C (PKC) and protein kinase A (PKA), is a pivotal regulatory mechanism of protein phosphorylation. Isolated rat cardiac myofibrils phosphorylated by PKC/PKA and dephosphorylated by PP1 were used in determining dephosphorylation specificities, Ca(2 ...

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 ...

Pulmonary embolism initially misdiagnosed as perimyocarditis in a young patıent

Annals of Cardiac Anaesthesia, 2022
Pulmonary embolism is a common cardiovascular emergency. In case of delayed diagnosis and treatment morbidity and mortality is high. In this report, we presented a case of pulmonary embolism without apparent risk factors, which was initially misdiagnosed

Cats with thermal burn injuries from California wildfires show echocardiographic evidence of myocardial thickening and intracardiac thrombi. [PDF]

, 2020
Recent increases in the prevalence and severity of wildfires in some regions have resulted in an increased frequency of veterinary burn patients. Few studies exist regarding diagnostics and management of burn wounds in veterinary patients and current ...
