Compact Terahertz Dual‐Comb Spectroscopy with All‐Digitally Generated Adaptive Clock

Advanced Physics Research, EarlyView.
This work demonstrates a compact terahertz dual‐comb spectrometer using an all‐digital adaptive clock generated on an FPGA. This system achieves high precision across 1.6 THz, resolves over 24 000 comb lines with kHz resolution, and offers enhanced stability and a simplified architecture compared to analog‐based methods.

Genome‐Wide DNA Methylation Study Reveals Specific Signatures in the Affected Arterial Tissue of Patients With Giant Cell Arteritis

Arthritis &Rheumatology, EarlyView.
Objective Giant cell arteritis (GCA) is a large‐vessel vasculitis, potentially causing complications such as blindness and strokes. This study aims to gain insights into the pathogenesis of GCA by identifying specific DNA methylation signatures in the arterial tissue of patients with this vasculitis. Methods DNA methylation profiling was analyzed in 79

Macrophage‐targeted cerium‐tannic acid metal‐polyphenol framework nanoenzyme promotes in situ heart valves regeneration through adaptive immunomodulation

BMEMat, EarlyView.
A novel nanoenzyme based on cerium ions‐tannic acid metal‐polyphenol framework (FCT) has been developed and loaded onto DHVs for targeting M1 macrophages to reduce their ROS level and reprogram macrophage phenotype, thereby eliminating inflammation, promoting endothelialization and adaptive matrix remodeling of scaffolds, offering a promising strategy ...
