The Different Facets of Myocarditis by Cardiac Magnetic Resonance Imaging

Heart Views
Myocarditis is an inflammatory condition affecting the myocardium and may have different etiologies. Patients usually present with chest pain and elevated levels of cardiac enzymes, mainly troponin. Cardiac magnetic resonance (CMR) imaging has emerged as

Perivascular Matrix Densification Dysregulates Angiogenesis and Activates Pro‐Inflammatory Endothelial Cells

Advanced Science, EarlyView.
Perivascular matrix densification promotes the emergence of aberrant endothelial tip cells (ATECs) that invade and persist within fibrotic microenvironments. Using in vivo lineage tracing and a human microvessel model, this study shows that fibrous matrix cues destabilize VE‐cadherin–mediated junctions to gate TGF‐β signaling, inducing a pro ...

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

PET Imaging of Cardiac Inflammation in Viral Myocarditis Using a DPP4‐Targeted Probe

Advanced Science, EarlyView.
This study describes a DPP4‐targeted PET probe for imaging myocardial inflammation by selectively targeting activated immune cells. Derived from the clinically approved small‐molecule inhibitor linagliptin, the probe demonstrates favorable biodistribution with specific cardiac uptake in myocarditis.

Unique association of cardiac amyloidosis and right atrial tumor thrombus in a patient with hepatocellular carcinoma

Radiology Case Reports, 2019
Tumor thrombus is a very rare complication observed in patients with hepatocellular carcinoma. We report a unique case of hepatocellular carcinoma with extension of tumor along the inferior vein cava into the right atrium, in a patient with cardiac ...

The AUTACE That Degrades KRAS and Engages CD8+ T Cells for the Treatment of KRAS/TP53 Co‐Mutant Tumors

Advanced Science, EarlyView.
AUTACE is a bifunctional nanoplatform that integrates tumor targeting, immune engagement, and on‐demand KRAS degradation. It targets KRAS/TP53 co‐mutant tumors via TP53‐specific TCRs, elicits antitumor CD8+ T‐cell responses through surface anti‐CD3 antibodies, and uses low‐intensity focused ultrasound (LIFU) to trigger controlled release of the KRAS ...
