Developing a Functional Polyelectrolyte Hybrid Layer Scaffold Coating and Evaluation of Its Performance for Interaction With Neural Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
Polyelectrolyte scaffold coatings modified with Cu and Fe3O4 nanoparticles regulate neural stem cell behavior in vitro. Increased Fe3O4 content enhances mitochondrial activity and neuronal differentiation, whereas higher Cu levels reduce cell viability.

Large‐Diameter DNA‐Scaffolded Nanopores Enabled by Loosely Packed Peptides for Single‐Molecule Sensing

open access: yesAngewandte Chemie, EarlyView.
A nanopore composed of transmembrane peptides and a DNA scaffold that assists peptide assembly was constructed. By employing peptides containing the unnatural amino acid 2‐aminoisobutyric acid (Aib), which promotes loose packing between helices, a large‐diameter nanopore was achieved.

Perivascular Matrix Densification Dysregulates Angiogenesis and Activates Pro‐Inflammatory Endothelial Cells

open access: yesAdvanced Science, EarlyView.
Perivascular matrix densification promotes the emergence of aberrant endothelial tip cells (ATECs) that invade and persist within fibrotic microenvironments. Using in vivo lineage tracing and a human microvessel model, this study shows that fibrous matrix cues destabilize VE‐cadherin–mediated junctions to gate TGF‐β signaling, inducing a pro ...

A Nonlinear Three-Phase Phase-Locked Loop Based on Linear Active Disturbance Rejection Controller

open access: yesIEEE Access, 2017
Three-phase phase-locked loops (PLLs) are the most widely used synchronization components in power systems. For common PLL algorithms, there is a tradeoff between the filtering capability and dynamic response.

PLL to the rescue [PDF]

open access: yesProceedings of the 53rd Annual Design Automation Conference, 2016
Electromagnetic injection (EMI) is a powerful and precise technique for fault injection in modern ICs. This intentional fault can be utilized to steal secret information hidden inside of ICs. Unlike laser fault injection, tedious package decapsulation is not needed for EMI, which reduces an attacker's cost and thus causes a serious information security

Lilrb4a Suppression Reprograms Microglia to Mitigate APOE4‐Associated Amyloid Plaques and Cerebral Amyloid Angiopathy in Association With a PPAR‐Linked Pro‐Clearance State

open access: yesAdvanced Science, EarlyView.
Targeting Lilrb4a in Apolipoprotein E4 (APOE4)‐associated Alzheimer's disease (AD) reprograms microglia toward a beneficial, phagocytic state. Genetic deletion or antisense inhibition of Lilrb4a suppresses p‐SHP2/NF‐κB/STAT1 signaling, restores PPAR‐linked lipid and energy metabolism, and reduces amyloid plaque burden and cerebral amyloid angiopathy ...

Recurrence of T-Cell Prolymphocytic Leukemia With a Rare Presentation as Diffuse Generalized Skin Lesion

open access: yesJournal of Investigative Medicine High Impact Case Reports, 2023
T-cell prolymphocytic leukemia (T-PLL) is a rare and aggressive neoplasm that originates from mature post-thymic T-cells. Cutaneous manifestations are a common presentation in T-PLL but rarely are a presentation in the recurrent setting.
