Multi‐Organelle Stress‐Induced Paraptosis by a ROS‐Amplifying Nanocatalyst for Enhanced Cancer Immunotherapy

Advanced Science, EarlyView.
The engineered TF‐Fe@LC nanoplatform programs paraptotic death via multipath ROS amplification that disrupts redox homeostasis, provoking mitochondrial dysfunction, autophagic blockade, and ER stress. This caspase‐independent process elicits robust immunogenic cell death, combining with αPD‐L1 to activate systemic CD8+ T‐cell immunity and suppress ...

PSMA8‐Containing 20S Proteasome Regulates Spermiogenesis and Male Fertility

Advanced Science, EarlyView.
PSMA8 assembles s20S proteasome that degrades specific substrates in elongating spermatids. Degradation of s20S‐substrates activates translation of FXR1‐target mRNAs, which are essential for mitochondrial sheath formation and sperm morphogenesis.

Force to Debond Brackets from High-fusing and Low-fusing Porcelain Systems [PDF]

, 2006
The purpose of this study was to test the hypothesis that porcelain surface finishing, ie, low- and high-fusing porcelain, has an effect on the amount of force required to debond orthodontic brackets. A total of 20 high-fusing and 20 low-fusing porcelain

Tailored Porous Bimetallic Nanozyme Platform for Full‐Cycle Therapeutics of Intestinal Ischemia/Reperfusion

Advanced Science, EarlyView.
ABSTRACT Intestinal ischemia/reperfusion (I/R) injury presents a biphasic pathology: an acute oxidative‐inflammatory phase leading to organ failure, and a recovery phase marked by mucosal dysfunction and bacterial translocation. The developed MPB@TA‐Cu‐Ma nanocomposite functions as a dual‐phase therapeutic platform with significant efficacy. It rapidly

Biomimetic Nanoplatform for Targeted Glioblastoma Therapy via Concurrently Triggering GPX4/DHODH Mediated Ferroptosis

Advanced Science, EarlyView.
Considering the great challenge in Glioblastoma multiforme (GBM) treatment, the authors designed and synthesized a multifunctional nanoplatform that effectively induced ferroptosis by synergetically inhibiting intrinsic intrisinc anti‐ferroptosis proteins, GPX4 & DHODH, and realized excellent in vitro and in vivo anti‐GBM effect.
