Dual‐Physical‐Field Nanocatalysis: Injectable Hydrogel Enables Piezo‐Photothermal Synergy for Breast Cancer Therapy

open access: yesAdvanced Science, EarlyView.
ABSTRACT Piezocatalytic therapy (PCT) harnesses mechanical energy to generate tumor‐lethal reactive oxygen species (ROS), but its efficacy is limited by rapid electron‐hole recombination and poor intratumoral retention. To overcome these limitations, we engineered heterostructured BiOCl@CuO nanosheets embedded in an injectable, conductive ...

ALKBH3 m1A Demethylase Deficiency Reduces Alzheimer's Amyloid‐β Pathology

open access: yesAdvanced Science, EarlyView.
This study identifies that ALKBH3‐driven m1A demethylation orchestrates Alzheimer's disease progression by disrupting mitochondrial and synaptic homeostasis. This epitranscriptomic mechanism suppresses PINK1‐mediated mitophagy via m1A erasure, leading to mitochondrial dysfunction, oxidative stress, elevated Aβ production, and impaired microglial ...

EUTHANASIA AND THE COUNTRIES WHICH POSITIVELY REGULATED ACTIVE EUTHANASIA

open access: yesJournal of Law and Sustainable Development
Objectives: The main objective of this article is to provide a comprehensive understanding of Euthanasia, also known as mercy-killing, and its various forms. It also aims to discuss the moral and legal implications of Euthanasia, which differ across countries, and examine the statutory frameworks of jurisdictions where Active Euthanasia has been ...

GHRHR Deficiency Enhances Retinal Ganglion Cell Survival and Visual Functions in Experimental Glaucoma by Inhibiting Ferroptosis

open access: yesAdvanced Science, EarlyView.
Glaucoma, a major cause of blindness, involves retinal ganglion cell (RGC) degeneration. This study shows growth hormone‐releasing hormone receptor (GHRHR) deficiency preserves RGC survival and restores vision, unlike activation which only aids survival.

MG53 Coordinates Macrophage Polarization and Neuroimmune Coupling to Promote Corneal Nerve Regeneration via the MPEG1–MVP–STAT6 Axis

open access: yesAdvanced Science, EarlyView.
Corneal nerve regeneration is critical to corneal wound healing processes. The current study reveals a novel role of MG53 in promoting corneal nerve regeneration after alkali induced injury. Mechanistically, MG53 enters macrophages via its receptor, MPEG1, promotes MVP K63 ubiquitination, and triggers STAT6 induced repair‐related genes expression ...

Brain and Liver Dual‐Targeting Oridonin Nanoparticles to Enhance Aβ Clearance for Alzheimer's Disease Therapy

open access: yesAdvanced Science, EarlyView.
We developed a nanoparticle named OAF, which simultaneously targeted to both the brain and liver via the transferrin receptor 1 (TfR1) receptor, promoting lipoprotein receptor‐related protein 1 (LRP1) expression to enhance amyloid‐beta (Aβ) clearance. In AD mice model, OAF significantly reduced Aβ deposition and cognitive impairment, while a mitigating

Albumin‐Bound STING Agonist Reprograms HSPCs to Antitumor Neutrophils Enhancing CD8+ T Cell Immunity

open access: yesAdvanced Science, EarlyView.
This study demonstrates that an albumin‐bound STING agonist (Nano ZSA‐51D) reprograms HSPCs to produce antitumor neutrophils with enhanced MHC I–mediated CD8+ T cell activation, thereby sensitizing tumors to α‐PD1 therapy. These findings highlight a strategy to target early hematopoiesis for shaping neutrophil fate and potentiating cancer immunotherapy.
