[Myocardial viability assessment].

Acta medica portuguesa, 2012
The prognosis for patients with chronic coronary artery disease and severe left ventricular dysfunction is poor, despite advances in different therapies. The assessment of myocardial viability has become an important aspect of the diagnosis, prognosis and management of patients with ischemic cardiomyopathy.

Beyond Transconductance: Cell‐Polymer Coupling Determines Fidelity in Action Potential Recording via Electrolyte‐Gated Polymer Transistors

Advanced Science, EarlyView.
High electrical performance alone does not guarantee efficient bioelectronic signal transduction. Despite excellent mixed ionic‐electronic conduction, recordings from cardiomyocytes reveal that p(g2T‐TT)‐based OECTs predominantly transduce field potential FP‐like signals due to weak cell‐polymer coupling.

From the Gut to the Brain: Microplastic‐Associated Neurovascular Dysfunction and Implications for Stroke Risk

Advanced Science, EarlyView.
Chronic oral exposure to microplastics may disrupt gut microbiota homeostasis and intestinal barrier integrity, potentially engaging the gut–brain axis and systemic inflammatory responses. These alterations may be associated with impaired blood–brain barrier function, cerebral microvascular dysfunction, and enhanced endothelial inflammation, pro ...

Remote Activation of Spinal TRPV1 by Magnetic Nanocubes Confers Cardioprotection Against Myocardial Ischemia‐Reperfusion Injury

Advanced Science, EarlyView.
Fe‐based magnetic nanocubes conjugated with TRPV1 antibodies (FeNCs‐TRPV1) are developed for the specific targeting of TRPV1 channels. Intraspinally injected FeNCs‐TRPV1 induces TRPV1 desensitization in rats exposed to repetitive and transient ACMF.

EDTA‐Functionalized Nanoscale Metal–Organic Framework for Onco‐Cardiology via Radiochemotherapy Synergy and Spatiotemporally Matched Iron Chelation

Advanced Science, EarlyView.
Doxorubicin (DOX)‐induced cardiotoxicity is a major limitation to its broader clinical application, while cardioprotective interventions often risk reducing the anticancer efficacy of DOX. To address these challenges, this work constructs an EDTA‐functionalized metal–organic framework that enhances tumor therapy and provides efficient cardioprotection ...

Engineering Immune Cell to Counteract Aging and Aging‐Associated Diseases

Advanced Science, EarlyView.
This review highlights a paradigm shift in which advanced immune cell therapies, initially developed for cancer, are now being harnessed to combat aging. By engineering immune cells to selectively clear senescent cells and remodel pro‐inflammatory tissue microenvironments, these strategies offer a novel and powerful approach to delay age‐related ...
