A functional cardiac patch promotes cardiac repair by modulating the CCR2 cardiac-resident macrophage niche and their cell crosstalk.

C-C chemokine receptor type 2 (CCR2) cardiac-resident macrophages (CCR2 cRMs) are known to promote cardiac repair after myocardial infarction (MI). However, the substantial depletion and slow recovery of CCR2 cRMs pose significant barriers in cardiac recovery. Here, we construct a functional conductive cardiac patch (CCP) that can provide exogenously elastic conductive microenvironment and induce endogenously reparative microenvironment mediated by CCR2 cRMs for MI repair.

Dual-band polarization-controlled metasurface with independent amplitude-phase coding for versatile beam forming.

Digital coding metasurfaces have gained considerable attention for their potential to bridge physical and information sciences. However, existing metasurfaces are often restricted to either phase-only or amplitude-only control and typically operate within a single frequency band or polarization, limiting their functionality in advanced electromagnetic applications. This study proposes a dual-band metasurface with independent amplitude-phase coding for polarization-controlled beam manipulation, addressing these limitations.

Virtual biopsy for non-invasive identification of follicular lymphoma histologic transformation using radiomics-based imaging biomarker from PET/CT.

Background: This study aimed to construct a radiomics-based imaging biomarker for the non-invasive identification of transformed follicular lymphoma (t-FL) using PET/CT images.

Methods: A total of 784 follicular lymphoma (FL), diffuse large B-cell lymphoma, and t-FL patients from 5 independent medical centers were included. The unsupervised EMFusion method was applied to fuse PET and CT images.

Association between exposure to 35 environmental pollutants and mortality from cerebrovascular diseases: A long-term prospective study.

Environmental pollutants have been implicated in various detrimental health effects. However, the specific relationship between environmental pollutant exposure and the risk of cerebrovascular disease mortality remains uncertain. This study aimed to comprehensively explore the potential relationship between environmental pollutant exposure and risk of cerebrovascular disease mortality in the U.
