Unlocking Li/Mg‐Based Photochemical Nitration Platforms for Anticancer Drug Discovery

open access: yesAdvanced Science, EarlyView.
Two low‐toxicity light main‐group metal photochemical systems based on lithium and magnesium are constructed for selective C(sp2)‐H (di)nitration of anilines. The obtained dinitrated products exhibit anti‐HCC (hepatocellular carcinoma) and anti‐KYSE30 cell activities, holding promise as novel antitumor candidates.

An Injectable and Self‐Reinforced Piezoelectric Hydrogel for Irregular Bone Defects Regeneration: Dynamic Epigenetic Regulation Approach

open access: yesAdvanced Science, EarlyView.
An injectable and self‐reinforcing RSF‐based piezoelectric hydrogel conforms to irregular bone defects and progressively strengthens in situ, overcoming the trade‐off between injectability and mechanical stability. Mechanical loading generates bioelectrical cues that promote P300‐mediated H3K9 acetylation and upregulate PTH1R expression, thereby ...

Cannabinoid CB1 Receptor in Nociceptors Mediates Postoperative Analgesia via ASIC3 Inhibition

open access: yesAdvanced Science, EarlyView.
CB1R and ASIC3 are co‐expressed in CGRP+ nociceptors of mouse DRG. Plantar incision triggers an upregulation of ASIC3 and activation of ASIC3+ neurons, driving mechanical allodynia. CB1R activation suppresses ASIC3 function and downstream ERK1/2 phosphorylation, thereby braking nociceptive signaling and accelerating pain resolution.

qcGEM: A Graph‐Based Molecular Representation With Quantum Chemistry Awareness

open access: yesAdvanced Science, EarlyView.
In this work, we introduce qcGEM, a quantum‐chemistry‐aware graph‐based embedding of molecules that incorporates physical priors into molecular representation learning. Through a specially designed model architecture to adequately process quantum chemistry information as well as three‐dimensional molecular geometry, qcGEM provides a compact, physics ...

Partial Wh-movement: Evidence from Malay

open access: yes, 2000
Partial wh-movement (PM) constructions have recently been the focus of investigation in a number of languages. For example, in German and Hungarian, an element described as a wh-expletive appears in the matrix Spec CP while the wh-word moves overtly to a

MN•CS•IO System: Cross‐Species Study for HBB Function in High‐Altitude Hypoxia Adaptation

open access: yesAdvanced Science, EarlyView.
We developed an integrative mesh‐nanorod sorting, chitosan nanoparticle delivery, and intraosseous injection (MN•CS•IO) system to investigate HBB in high‐altitude hypoxia adaptation. Transplanting Tibetan animals' HBB‐modified Lin‐ cells into mice achieved 95.59% transfection efficiency and 8.15% HBB expression. High‐altitude HBB recipients upregulated

Huntingtin Aggregate‐Responsive Autophagy Gene Circuit Mitigates Disease Pathology in R6/2 Mice

open access: yesAdvanced Science, EarlyView.
CD98‐mediated receptor‐mediated transcytosis enables LIP‐CD98 nanocarriers to cross the blood–brain barrier and deliver ARAA to neurons. mHTT aggregates activate the 11G–NarX sensor, initiating Auto‐P and Trans‐P signaling through the VP48–NarL relay.

Opposite Trap‐State Evolution Pathways Govern Endurance and Retention Failure in Amorphous Chalcogenide Memory

open access: yesAdvanced Science, EarlyView.
GeSbSe selector‐only memory devices are investigated through physical and electrical analyses to reveal opposite trap‐state evolution pathways governing reliability degradation. Endurance cycling drives Se migration, transitioning traps from deep to shallow states.
