Ultrasound Modulation of Visual Circuits in Mice Independent of Auditory Confound

Advanced Science, EarlyView.
In this study, Qiu et al. found that low‐intensity ultrasound can directly activate sparse ultrasound‐sensitive neurons (UNs) in the primary visual cortex (V1) of deafened mice. The proportion of these sparse UNs is pressure‐dependent. Furthermore, ultrasound modulates visual circuitry with distinct excitatory and inhibitory effects.

Role of Diffusion Tensor Imaging in Diagnosis and Estimation of Shunt Effect for Hydrocephalus in Stroke Patients: A Narrative Review

Diagnostics, 2022
Hydrocephalus is a dilatation of the brain ventricular system by the accumulation of cerebrospinal fluid within the ventricle caused by impaired cerebrospinal fluid circulation or clearance. A diagnosis of hydrocephalus at the chronic stage of stroke has

Linear accelerators

, 2013
Radio-frequency linear accelerators are used as injectors for synchrotrons and as stand-alone accelerators for the production of intense particle beams, thanks to their ability to accelerate high beam currents at high repetition rates.

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

Reproducing Patient-Specific Hemodynamics in the Blalock–Taussig Circulation Using a Flexible Multi-Domain Simulation Framework: Applications for Optimal Shunt Design

Frontiers in Pediatrics, 2017
For babies born with hypoplastic left heart syndrome, several open-heart surgeries are required. During Stage I, a Norwood procedure is performed to construct an appropriate circulation to both the systemic and the pulmonary arteries.

Nanoparticle‐Mediated Immunometabolic‐Epigenetic Remodeling Enhances Schwann Cell‐Macrophage Interaction for Sciatic Nerve Regeneration

Advanced Science, EarlyView.
A biomimetic Prussian White nanoparticle (PW) is engineered to achieve long‐term local retention and orchestrate immunometabolic‐epigenetic remodeling for sciatic nerve regeneration. PW directly targets hexokinase 2 to suppress glycolysis, thereby elevating α‐ketoglutarate and driving Kdm4a/b‐mediated demethylation of H3K9me3.

Information value of magnetic resonance imaging in shunted hydrocephalus. [PDF]

Archives of Disease in Childhood, 1994
To study the role of magnetic resonance imaging (MRI) in evaluating children with shunted hydrocephalus.Sixty one asymptomatic children with shunted hydrocephalus or cystic cerebrospinal fluid collections were studied by cranial MRI. The information obtained from the images was classified into three categories: provided (1) a new diagnosis, (2 ...

Robust and Tailored 1D/3D Heterojunction for Efficient and Stable Perovskite Solar Cells

Advanced Science, EarlyView.
This study successfully established a robust 1D/3D heterojunction, characterized by a stable 1D phase, favorable lattice matching, strong interface binding, and effective defect passivation. The resulting epitaxial perovskite film demonstrates preferential vertical orientation of (100) facets, thereby facilitating carriers’ transport and stress relief.
