Advances and Perspectives in Graphene‐Based Quantum Dots Enabled Neuromorphic Devices

Advanced Science, EarlyView.
Graphene‐based QDs are zero‐dimensional carbon nanomaterials with pronounced quantum confinement and tunable electronic structures. Herein, we summarize their synthesis strategies and functionalization methods, and highlight their functional roles and operating mechanisms in devices, as well as recent advances in neuromorphic electronics. We anticipate

Defence/Military

Feminist-informed foreign policies seek to transform the global gender order, rather than reproducing narrow definitions of security tied solely to the state. Yet the increasing militarization of state foreign policies has had less attention paid to it than might be expected given the growth of war and conflict globally. This chapter examines where and

Supramolecular Assembly of Stepped‐Persistent ROS Nanogenerator for Sustained Tumor Immunotherapy

Advanced Science, EarlyView.
ROS catalytic systems often fail to achieve both effective tumor elimination and persistent immune activation due to their monotonous ROS production profiles. A stepped‐persistent ROS nanogenerator was developed by supramolecularly assembling multiple ROS generation modules within a nanofiber structure to simultaneously extend ROS generation duration ...

Senescent Cell Derived Artificial Vesicle‐Based Senolytic Sonovaccine Platform with Augmented Lymph Node Delivery and Antigen Cross‐Presentation Efficacy

Advanced Science, EarlyView.
A senolytic sonovaccine platform (SenoVac) is developed, in which senescent cell‐derived vesicles serve as broad senescent cell antigen reservior. The “2‐step” click chemistry strategy for effective lymph node delivery, and ultrasound‐triggered endosomal escape to boost cross‐presentation, ensures efficient senescent cell clearance and disease ...

IKKβ and USP28 Regulate HEY1 Stability to Promote Cancer Stemness and Immune Evasion in Hepatocellular Carcinoma

Advanced Science, EarlyView.
The uncovered IKKβ‐USP28‐HEY1 axis fuels cancer stemness and immune evasion in hepatocellular carcinoma. USP28 deubiquitinates HEY1 upon IKKβ‐mediated phosphorylation, conferring PD‐1/PD‐L1 blockade resistance. Pharmacological inhibition of USP28 sensitizes resistant tumors to anti‐PD‐1 immunotherapy, revealing a promising therapeutic strategy ...

Melatonin Alleviates Graft Biliary Fibrosis by Inhibiting VIM+ Cholangiocyte Subcluster via Hypoxia/TGF‐β‐CREM‐VIM Axis

Advanced Science, EarlyView.
Single‐cell RNA sequencing verified the presence of the VIM+ biliary epithelial cell (BEC) in the bile ducts of NAS patients. The hypoxia/TGF‐β‐CREM‐VIM axis mediated phenotypic switch toward VIM+ BEC is validated using a hypoxia/TGF‐β‐stimulated cellular model, a rat liver transplantation model, BEC‐specific Crem conditional knockout rats, and BEC ...

Traumatic Brain Injury and Firearm Use and Risk of Progressive Supranuclear Palsy Among Veterans

Frontiers in Neurology, 2018
Background: Progressive supranuclear palsy (PSP) is a tauopathy that has a multifactorial etiology. Numerous studies that have investigated lead exposure and traumatic brain injury (TBI) as risk factors for other tauopathies, such as Alzheimer's disease,

A Sprayable Nanoplatform Breaks the Vicious Cycle of Diabetic Wounds via Photoactivated Antioxidant and Drug Delivery

Advanced Science, EarlyView.
A sprayable near‐infrared‐activated nanoplatform incorporating MXene, ZnHCF nanozyme, and deferoxamine efficiently breaks the vicious cycle of diabetic wounds. Upon irradiation, interfacial electron transfer and photothermal effects enhance multi‐enzyme activity, enabling explosive ROS elimination, alleviation of hypoxia, and controlled DFO release ...
