Onset of cardiac iron loading in pediatric patients with thalassemia major

Haematologica, 2008
We reviewed cardiac T2* assessments from 77 thalassemia major patients between the ages of 2.5 and 18 years to study optimal timing of cardiac iron screening by magnetic resonance imaging.

Electroactive Liquid Crystal Elastomers as Soft Actuators

Advanced Functional Materials, EarlyView.
Electroactive liquid crystal elastomers (eLCEs) can be actuated via electromechanical, electrochemical, or electrothermal effects. a) Electromechanical effects include Maxwell stress, electrostriction, and the electroclinic effect. b) Electrochemical effects arise from electrode redox reactions.

Water–fat Dixon cardiac magnetic resonance fingerprinting

Magnetic Resonance in Medicine, 2019
Cardiac magnetic resonance fingerprinting (cMRF) has been recently introduced to simultaneously provide T1, T2, and M0 maps. Here, we develop a 3‐point Dixon‐cMRF approach to enable simultaneous water specific T1, T2, and M0 mapping of the heart and fat ...

Preliminary Study of a Ninj1‐Loaded Bimodal Ultrasound/NIR Fluorescence Targeted Molecular Probe for Diagnosing Early‐Stage Inflammation in Coronary Microvascular Dysfunction

Advanced Healthcare Materials, EarlyView.
Coronary microvascular dysfunction (CMD) targeting remains a challenge for precise diagnosis. This work presents a dual‐modal nanoprobe (T‐IR780‐NBs) that combines ultrasound contrast with near‐infrared fluorescence. This technology utilizes proteomics‐derived antibodies that specifically localize to inflamed and injured cardiac tissue, enabling ...

Abnormal elevation of myocardial necrosis biomarkers after coronary artery bypass grafting without established myocardial infarction assessed by cardiac magnetic resonance

Journal of Cardiothoracic Surgery, 2017
Background The diagnosis of peri-procedural myocardial infarction is complex, especially after the emergence of high-sensitivity markers of myocardial necrosis. Methods In this study, patients with normal baseline cardiac biomarkers and formal indication

Antimicrobial Efficacy of a Taurolidine‐Based Antimicrobial Compound on Contaminated Surfaces Simulated in a Standardized 4‐Field Test

Advanced Healthcare Materials, EarlyView.
As implantable medical devices become indispensable to modern medicine, a silent threat grows alongside them: device‐associated infections. Despite decades of antibiotic innovation, infection rates keep climbing, costing lives and billions in healthcare expenses.
