A Herbal‐Piezoelectric Heterojunction Strategy to Potentiate Bacterial Cuproptosis‐Like Death and Remodel the Inflammatory Microenvironment in Infection‐Associated Implant Osteomyelitis

open access: yesAdvanced Science, EarlyView.
A titanium implant coating integrating berberine and copper‐doped strontium titanate leverages ultrasound to compromise bacterial membranes and induce cuproptosis‐like death. This approach resolves S. aureus infections in osteomyelitis models while suppressing inflammation and promoting osseointegration, demonstrating a dual‐functional strategy against

Modeling the effects of wind tunnel wall absorption on the acoustic radiation characteristics of propellers [PDF]

open access: yes, 1986
Finite element theory is used to calculate the acoustic field of a propeller in a soft walled circular wind tunnel and to compare the radiation patterns to the same propeller in free space.

TREM2‐Mediated Cholesterol Efflux in Macrophages Inhibits Anti‐Tumor Immunity via Limitation of CD4+ T and NK Cells

open access: yesAdvanced Science, EarlyView.
Impaired anti‐tumor immunity is mediated by TREM2 + macrophages in non‐small cell lung cancer. TREM2 + macrophages prevent anti‐tumor immunity depending on the limitation of CD4 + T and NK cells. TREM2 promotes cholesterol efflux via ABCA1 to limit the production of CX3CL1 in macrophages.

METTL10‐Mediated PIAS3 Methylation Links Purine Metabolism to Gastric Cancer Progression

open access: yesAdvanced Science, EarlyView.
METTL10‐mediated methylation of PIAS3 at K442 inhibits its SUMO E3 ligase activity toward MITF. This reduces MITF SUMOylation and subsequent RNF4‐mediated ubiquitination, leading to MITF protein accumulation and gastric cancer progression. Abstract Metabolic dysregulation plays a significant role in the development of gastric cancer (GC).

Multimodal Imaging Reveals Cerebral Microcirculation Dynamics and Mechanisms in Mouse Central Nervous System After Intranasal Infection With Recombinant Pseudorabies Virus

open access: yesAdvanced Science, EarlyView.
Multi‐modality imaging strategy applied to PRV‐induced central nervous system infection enables dynamic visualization of cerebrovascular dysfunction, including hyperemia, hypoperfusion, and vascular remodeling. These changes are linked to microglial activation and impaired angiogenesis, providing mechanistic insight into PRV neuropathogenesis and ...

Targeting ROCK2 to Restore Epileptic Synaptic Networks via Mitophagy Activation: Insights from Translational Imaging of SV2A In Vivo

open access: yesAdvanced Science, EarlyView.
By integrating synaptic vesicle glycoprotein 2A PET imaging and transcriptomics, this study identifies Rho‐associated protein kinase 2 (ROCK2) as a critical regulator of synaptic network dysfunction in temporal lobe epilepsy. Pharmacological ROCK2 inhibition restores synaptic density and enhances mitophagy, thereby reducing seizures and neuronal damage.

cGAS Inhibits ALDH2 to Suppress Lipid Droplet Function and Regulate MASLD Progression

open access: yesAdvanced Science, EarlyView.
cGAS is a cytosolic DNA sensor known for innate immune defense. cGAS binds and suppresses ALDH2 are showed, limiting acetyl‐CoA production. cGAS loss activates ALDH2, promoting histone acetylation, lipogenesis, and lipid droplets accumulation. cGas‐/‐ mice on a high‐fat diet show signs of worsened MASLD.

Wind tunnel measurements of forward speed effects on jet noise from suppressor nozzles and comparison with flight test data [PDF]

open access: yes
The results of a test program conducted in the NASA Ames 40- by 80-Foot Wind Tunnel to determine the effect of forward speed on the noise levels emanating from a conical ejector nozzle, a 32-spoke suppressor nozzle, and a 104-elliptical-tube suppressor ...
