Conjugated Porphyrin Polymer With Superior Charge Transfer for Photodynamic‐Immunomodulatory Prevention of CIED Infection in Diabetes

Advanced Healthcare Materials, EarlyView.
Under NIR irradiation, PTCPP generates ROS to eliminate MRSA biofilms and promote M1 macrophage polarization for phagocytosis. After bacterial clearance, the material is phagocytosed by macrophages, shifting their polarization to M2 phenotype via metabolic reprogramming, which synergistically enhances anti‐infection therapy and wound healing.

Calmodulinopathy: Functional Effects of CALM Mutations and Their Relationship With Clinical Phenotypes

Frontiers in Cardiovascular Medicine, 2018
In spite of the widespread role of calmodulin (CaM) in cellular signaling, CaM mutations lead specifically to cardiac manifestations, characterized by remarkable electrical instability and a high incidence of sudden death at young age.

How Cardiac Embryology Translates into Clinical Arrhythmias

, 2021
The electrophysiological signatures of the myocardium in cardiac structures, such as the atrioventricular node, pulmonary veins or the right ventricular outflow tract, are established during development by the spatial and temporal expression of ...

Microfluidic Droplet Plate Preserving Single Human Induced Pluripotent Stem Cell‐Derived Cardiomyocytes Morphology and Function

Advanced Materials Technologies, EarlyView.
We introduce a novel method combining microfluidics, optogenetics, and human induced pluripotent stem cell (iPSC) technology to encapsulate single iPSC‐derived cardiomyocytes (iPSC‐CMs) in an optimal environment for functional characterization. This method enables direct genotype‐phenotype correlation for genetic studies and high‐throughput screening ...

Heart arrhythmias and conduction disorders in patients with acromegaly: the role of cardiac magnetic resonance imaging

Терапевтический архив, 2020
Cardiovascular complications including arrhythmias and cardiac conduction disorders are one of the main reasons of high mortality rate in acromegaly, while they have not been well explored. Aim.To estimate arrhythmias frequency in acromegaly, identify
