Constraints on coronal turbulence models from source sizes of noise storms at 327 MHz

, 2011
We seek to reconcile observations of small source sizes in the solar corona at 327 MHz with predictions of scattering models that incorporate refractive index effects, inner scale effects and a spherically diverging wavefront.

Iron Oxide Nanozyme as Reactive Oxygen and Nitrogen Species Scavenger to Regulate Microglial Homeostasis in Stroke

Advanced Science, EarlyView.
6 nm iron oxide nanoparticles (IONP6) exhibit enzyme‐like activities that scavenge reactive oxygen and nitrogen species (RONS), including nitric oxide (NO). In stroke models, IONP6 promotes microglial polarization toward the M2 phenotype, reduces neuroinflammation, and improves neurological outcomes, offering a promising drug‐free approach to mitigate ...

A BioLiving Periosteum Evokes Centripetal Regeneration in Challenging Bone Defects

Advanced Science, EarlyView.
Large bone defects often suffer from insufficient central healing. This study engineers a BioLiving periosteum that mimics the native structure. It sequentially delivers remote chemical cues and contact physical cues in a signaling‐relay manner, effectively recruiting and guiding endogenous cells toward the defect center.

Nature‐Inspired Surface Modification Strategy Reverses the Autophagic Flux Impairment of Mitochondrial Transplantation for Attenuating Ischemic Strokes

Advanced Science, EarlyView.
The functionalized starch modifies the mitochondrial surface and encapsulates resveratrol into the cavity of helices, facilitating a novel mitochondrial transplantation platform (MLSR). Upon internalization in recipient cells, MLSR triggers mitophagy and maintains positive autophagic flux through RIP1/RIP3 pathway inhibition.

The intramedullary anatomy of the distal fibula as it pertains to current fibular nail offerings: A CT scan analysis

Foot & Ankle Surgery: Techniques, Reports & Cases
There has been recent increased interest in intramedullary fibular nails for the treatment of fibular fractures. While most publications highlight the clinical outcomes and decreased complication rates associated with fibular nails in comparison to their

Identification of a Force‐Induced Sox9+Acan+ Transitional Subpopulation Linked to FGF2–FGFR2–ERK Signaling in Orthodontic Bone Remodeling

Advanced Science, EarlyView.
Mechanical loading induces a previously unrecognized Sox9+Acan+ transitional mesenchymal cell population in the periodontal ligament that promotes osteoclastogenesis via the FGF2–FGFR2–ERK axis. Targeting this mechanoresponsive stromal population using a localized GelMA@siRNA delivery strategy attenuates pathological osteoclast overactivation and root ...

Cortical Somatostatin Neurons Regulate Seizure Susceptibility via MINAR1/Gαs–cAMP Signaling

Advanced Science, EarlyView.
Our study identifies MINAR1 as a novel regulator of cortical interneuron excitability and seizure susceptibility. MINAR1 is preferentially expressed in SST+ interneurons. Genetic ablation of MINAR1 leads to seizure hypersensitivity, reduced SST+ neuron excitability, and impaired Gαs–cAMP signaling, disrupting the E/I balance.

Multimodal Layer‐Crossing Interrogation of Brain Circuits Enabled by Microfluidic Axialtrodes

Advanced Science, EarlyView.
The study introduces a flexible microfluidic axialtrode that integrates optical, electrical, and chemical modalities within a single polymer fiber. By redistributing electrodes and fluidic channels along the fiber axis via angled cleaving, it enables simultaneous optogenetic stimulation, electrophysiological recording, and drug delivery across brain ...

Limits on diffuse X-ray emission from M101 [PDF]

Observed limits on diffuse X-ray emission from M101 require that the temperature of any coronal or matrix hot gas which is radiating an appreciable part ( 10%) of the average supernova power be less than 10(5.7)K.

ACSL1‐Dependent Microglial Lipoimmunometabolic Reprogramming Underlies Cognitive Deficits in Alcohol Use Disorder

Advanced Science, EarlyView.
This study reveals that chronic alcohol exposure selectively upregulates ACSL1 expression in prefrontal cortical microglia, driving lipid metabolism reprogramming and lipid droplet accumulation, which activates the NLRP3 inflammasome and sustains neuroinflammation. To reverse this process, a dual‐targeted lipid nanoparticle, siACSL1@LNP‐MR, is designed
