Comparative evaluation of three obturation techniques on the push-out bond strength of two bioceramic sealers: An in vitro study

Journal of Oral Research and Review
Introduction: For endodontic therapy to be successful, the root canal system must be well sealed. This study evaluated the push-out bond strength of two bio ceramic sealers: CeraSeal and MTA-Fillapex using three obturation techniques: cold lateral ...

Persistent Zn2+ Influx‐Mediated Deacetylation of ANXA2 Regulates the “Zn2+‐Autophagic Flux” and Alleviates Intervertebral Disc Degeneration

Advanced Science, EarlyView.
Zinc transporter SLC39A14 sustains intracellular Zn2+ levels to activate SIRT3‑dependent ANXA2 deacetylation at K302. This modification weakens ANXA2‑mTOR binding and releases autophagic‑flux suppression in nucleus pulposus cells. Dysregulated Zn2+ homeostasis disrupts this axis to drive intervertebral disc degeneration.

Active Oscillations of Elastic Membranes Arising from the Coupling with a Catalytic Reaction

Advanced Science, EarlyView.
Coupling an elastic membrane to a catalytic reaction produces active oscillations that self‐sustain for hours: the membrane cyclically inflates and deflates as the reaction spontaneously activates and deactivates, without external power. Energy release is directly embodied in the oscillation dynamics, opening elasto‐chemical strategies for the physical

Real‐Time Monitoring of Mass and Mechanical Properties in Single Cells and Multicellular Spheroids

Advanced Science, EarlyView.
This study introduces photothermally actuated microcantilevers combined with optical microscopy to simultaneously measure morphology, mass, and mechanical properties of cellular systems in real‐time. The findings link cytoplasm‐dominated mechanical energy dissipation to the Q‐factor as a novel biophysical parameter.

Stretchable h‐BN/TPU Fibers for Passive‐Active Dual‐Mode Thermal Management and Wearable Haptic Interfaces

Advanced Science, EarlyView.
Optimized 30 wt.% h‐BN/TPU fibers create a thermal conductivity of 2.08 W·m−1·K−1 while retaining mechanical compliance (422% elongation at break). Woven fabrics reduce surface temperature by 5.7°C under simulated solar irradiation. Glove integration enables localized fingertip heating at 29.55°C·s−1 with a thermal relaxation time of approximately 20 s.

LigHTS: Biomimetic Hydrogel Photo‐Fabrication for Imaging‐Based Ultra‐High‐Throughput Screening

Advanced Science, EarlyView.
LigHTS removes a key bottleneck for ultra‐high‐throughput screening (UHTS) by enabling biomimetic hydrogel microenvironments to be manufactured directly in standard multiwell plates. A single, collimated UV exposure with formulation‐tuned light penetration patterns an entire plate with UHTS‐grade uniformity (<20% CV), producing structured GelMA films ...

Study of warm compaction of Alumix 123 L

, 2010
Although powder metallurgy (PM) material is dominated by ferrous alloys, there is a growing interest in Al PM. The usage of Al PM in automotive applications depends on the development of higher density and improved dynamic properties.

Therapeutic Peptide‐Programmed Liquid‐Crystalline Topology Switching for pH‐Gated Postoperative Cancer Immunotherapy

Advanced Science, EarlyView.
A VDAP‐programmed liquid‐crystalline depot enables pH‐responsive postoperative immunotherapy for triple‐negative breast cancer. VDAP stabilizes a leakage‐resistant HII mesophase through peptide–lipid electrostatic assembly, whereas tumor acidosis unlocks the matrix and promotes graded topology remodeling toward a bicontinuous Im3̄m cubic phase for ...
