DNA methylation-based telomere length is more strongly associated with cardiovascular disease and long-term mortality than quantitative polymerase chain reaction-based telomere length: evidence from the NHANES 1999–2002

open access: yesClinical Epigenetics
Background Telomere length (TL) serves as a pivotal gauge of cellular aging, with shorter TL linked to various age-related ailments. Recently, a DNA methylation-based TL estimator, known as DNAmTL, has emerged as a novel TL measurement tool.

High‐Resolution and Surface‐Sensitive Tip‐Enhanced Raman Spectroscopy Characterization of Strained‐Silicon Devices through Cleanroom‐Compatible Plasmonic Probes

open access: yesAdvanced Materials Interfaces, EarlyView.
This paper demonstrates how Tip‐Enhanced Raman Spectroscopy (TERS) can detect diverse levels of strain in a SiGe‐Si structure in less than 20 nm of depth with lateral resolution under 100 nm. The measures are performed with a TiN‐coated probe, which secures a remarkable enhancement of the optical signal, while being chemically stable to allow TERS to ...

3D Printed Magnetic Origami Scaffolds for Guided Tissue Assembly

open access: yesAdvanced Materials Interfaces, EarlyView.
3D‐printed magnetic origami scaffolds enhance 3D coculture by directing cell proliferation pre‐folding, restricting expansion for controlled growth within the channel, and spatially and temporally promoting 3D multicellular dissemination post‐folding.
