Protosappanin A Alleviates Atherosclerosis by Regulating the MDM2/GPX4 Axis‐Mediated Endothelial Ferroptosis

open access: yesPhytotherapy Research, EarlyView.
PTA alleviates atherosclerosis by regulating the MDM2/GPX4 axis‐mediated endothelial ferroptosis. ABSTRACT Endothelial ferroptosis is a crucial pathogenic driver of atherosclerosis (AS) progression. Protosappanin A (PTA), a bioactive compound from Caesalpinia sappan L., protects cardiovascular vessels by regulating ferroptosis.

Protective Potentials of Natural Products Against Vascular Dementia: A Comprehensive Review of Experimental Studies

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Vascular dementia (VaD), accounting for up to 20% of dementia cases globally, is primarily driven by chronic cerebral hypoperfusion (CCH), which leads to progressive cognitive impairment. Despite the increasing prevalence of VaD, effective treatments remain limited.

Neurotrophic Signaling, Sleep Physiology, and Retinal Neuroprotection: Integrative Mechanisms and Therapeutic Implications for Glaucoma

open access: yesSensory Neuroscience, EarlyView.
Glaucoma is increasingly understood as a neurodegenerative disorder shaped by sleep and circadian physiology, not intraocular pressure alone. Sleep loss and obstructive sleep apnea suppress BDNF–TrkB neurotrophic signaling, impair sleep‐dependent glymphatic clearance, and trigger microglial neuroinflammation and vascular insult at the optic nerve head,

Intelligent Continuum Micromachines in Complex Confined Spaces

open access: yesSmartBot, EarlyView.
The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...

PDA‐Engineered 3D‐Printed Polymer–ZrO2 Hybrid Scaffolds Enabling Enhanced Radiopacity, Photothermal Therapy, and Cell Migration Modulation

open access: yesSmall, EarlyView.
A multifunctional 3D‐printed polymer–ZrO2 scaffold is developed to provide intrinsic radiopacity, photothermal responsiveness, and surface bioactivity. Reinforcement with ZrO2 enables real‐time x‐ray visibility and mechanical robustness, while a polydopamine coating facilitates near‐infrared‐triggered drug release and modulates cell migration, thereby ...

Endocytosis‐independent cytosolic entry of messenger RNA via fluorous bilayer zippering attenuating Toll‐like receptor signaling and enables ischemic tissue salvage

open access: yesSmart Molecules, EarlyView.
The present study establishes a paradigm shift in synthetic mRNA delivery through the convergence of three orthogonal chemistries—perfluoro‐acylation, bio‐orthogonal click cross‐linking, and disulfide reduction—within a single, modular polymer architecture. Abstract A fundamental constraint of conventional messenger RNA (mRNA) delivery systems is their

Halting the Progression of Acute Kidney Injury: A Tubular‐Inspired Reusable Detoxifier Against Protein‐Bound Uremic Toxins and Oxidative Stress

open access: yesSusMat, EarlyView.
This graphical ToC illustrates a tubular‐inspired detoxifier (SDCMs–DS) that halts acute kidney injury progression. Inspired by proximal tubular epithelial cells (PTECs), the biomimetic design combines dissociation‐adsorption clearance of protein‐bound uremic toxins (PBUTs) with antioxidant protection. During hemoperfusion, danshensu (DS) released from
