A Citrulline‐Functionalized Patch Coordinates Macrophage NRF2 Signaling and Arginine Metabolism for Tendon‐to‐Bone Repair

open access: yesAdvanced Science, EarlyView.
A locally implanted patch combines citrulline‐functionalized carbon dots, a thioketal‐containing membrane coating from tendon‐derived stem cells, and aligned core–shell fibers. In macrophages, the patch reduces inflammatory markers and enhances antioxidant signaling through nuclear factor erythroid 2‐related factor 2 (NRF2); in rats and rabbits, it ...

Bearing Currents and Shaft Voltages in Electric Motors and Their Relationship to Pulse Width Modulation Drives

open access: yes, 2019
Modern variable frequency drives (VFD) have become the foundation of industrial electric motor control. However, observation of harmful effects has been found from the integration of these drives into existing systems.

Hierarchical Organization of Biomaterials in the Formation of Photonic Nanostructures

open access: yesAdvanced Science, EarlyView.
Natural organisms create vibrant structural colors through precisely organized nanostructures formed under mild biological conditions. This review explores how cellulose, chitin, corneous beta‐protein, and melanin form complex nanostructures across molecular, mesoscale, and tissue levels.

Localized Hydrogen Release Driven by Mg–Pd Microgalvanic Cells from 3D‐Printed Microneedles Reverses Redox Homeostasis for Psoriasis Treatment

open access: yesAdvanced Science, EarlyView.
A 3D printing microneedle (MP‐MN), loading magnesium‐based micro‐galvanic cells (MP), is designed for improving psoriasis. H2 generated from MP‐MN scavenges ROS and •OH, actives NRF2‐KEAP1 pathway, and decreases inflammation, thereby effectively restoring the oxidative stress homeostasis of psoriatic skin and suppressing the excessive proliferation of ...

Synchronization of Analog Neuron Circuits With Digital Memristive Synapses: An Hybrid Approach

open access: yesAdvanced Electronic Materials, EarlyView.
An hybrid circuit mimicking neural units coupled using memristive synapses is introduced. The analog neurons provide flexibility and robustness, and the digital memristive coupling guarantees the full reconfigurability of the interconnection. The onset of a synchronized spiking behavior in two circuits mimicking the Izhikevich neuron is discussed from ...

Allium sativum, a Natural and Pharmaco‐Remedial Panacea for Entero‐Gastritis, Antibiocidal/Dysbiogenesis, and Systemic Health Relevance

open access: yesAgriFood: Journal of Agricultural Products for Food, EarlyView.
Natural Pharmaco‐remedial impacts of Allium sativum on Systemic health. ABSTRACT Arising from the emergence of diverse difficult‐to‐treat health cases, alterative‐therapeutic strategies have become a potential way forward for management/control. In traditional Chinese medicine (TCM), various plant materials have been sourced as alterative‐therapeutic ...

Determinants of Knowledge and Usage of Generative Artificial Intelligence in Agricultural Extension: Evidence From Tennessee Extension Personnel

open access: yesAgribusiness, EarlyView.
ABSTRACT This paper examines the determinants of generative AI (GenAI) knowledge and usage among agricultural extension professionals. Drawing on survey data from agricultural extension personnel in Tennessee, we employ regression analyses and latent Dirichlet allocation (LDA) for topic modeling of open‐ended responses to study the knowledge and usage ...
