Deterministic Fiber‐Optic Spectral Engineering Enables Three‐Color Multiplexed Two‐Photon Microscopy

open access: yesLaser &Photonics Reviews, EarlyView.
A simulation‐guided spectral‐engineering framework maps the nonlinear parameter space of a fiber laser platform to identify balanced three‐band excitation states. The resulting 960, 1080, and 1175 nm femtosecond pulses deliver nJ‐level energies for low‐cross‐talk chromatically multiplexed two‐photon microscopy.

Advances in GPCRs Associated With Wnt Signaling Within the Auditory System

open access: yesMedicine Bulletin, EarlyView.
ABSTRACT G protein‐coupled receptors (GPCRs) that interact with the Wnt signaling pathway are pivotal for auditory system homeostasis, as they orchestrate inner ear development, hair cell (HC) regeneration, and hearing preservation. Frizzled (FZD) receptors, the core Wnt‐related GPCRs, bind Wnt ligands and co‐receptors (e.g., LRP5/6) to activate both ...

The Role of HUWE1 on Mouse Neural Cell Proliferation and Zebrafish Neurodevelopment

open access: yesMedicine Bulletin, EarlyView.
ABSTRACT The HECT, UBA, and WWE domain‐containing E3 ubiquitin protein ligase 1 (HUWE1) gene is located on the X chromosome and has been implicated in neurodevelopmental disorders. However, the mechanisms by which HUWE1 dosage affects nervous system development remain poorly understood. In this study, we demonstrate that HUWE1 overexpression suppresses

Distinct Brain Drivers and Shared Cerebello–Cortical Input in ADCY5 and SGCE Hyperkinetic Movements

open access: yesMovement Disorders, EarlyView.
Resting‐state fMRI and effective connectivity revealed distinct cerebellar–basal ganglia–cortical interactions in ADCY5 (MxMD‐ADCY5) and SGCE (MYC/DYT‐SGCE) related movement disorders. The cerebellum modulated cortex directly in MYC/DYT‐SGCE, but indirectly via basal ganglia‐cerebellar projections in MxMD‐ADCY5, which also showed reduced subthalamic ...

Frequency of ZFHX3‐Mediated Spinocerebellar Ataxia 4 in a US Undiagnosed Ataxia Cohort

open access: yesMovement Disorders, EarlyView.
Abstract Background Spinocerebellar ataxia 4 (SCA4) is a late‐onset dominant ataxia with neuropathy caused by exonic GGC repeat expansion in the ZFHX3 gene thought to originate from a Swedish founder event. The GC‐rich expansion is highly thermodynamically stable, posing challenges for standard clinical genetic testing methods.

SNR‐Efficient Inhomogeneous Magnetization Transfer (ihMT) for Clinical Applications at 7 T

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Inhomogeneous MT (ihMT) is an MRI modality sensitive to Myelin, the lipid‐rich membrane surrounding the axons. A novel ihMT saturation strategy and its associated B1+$$ {\mathrm{B}}_1^{+} $$ correction at UHF are proposed. The aim is to generate a strong ihMT effect within a clinically compatible scan time while complying with SAR ...
