Rapid estimation of structural brain disconnection from binary lesion masks using DeepDisco

Abstract Mapping how focal brain lesions disrupt structural connectivity is key to understanding cognition, behavior, and neurological outcomes. However, traditional diffusion tractography pipelines are computationally intensive, require specialized data and expertise, and remain...

Wild-type and mutated ß-catenin differently repress RND3/RHOE expression in hepatocellular carcinoma

Tumor development and progression are mainly driven by oncogenic mutations but are also regulated by physical factors. Through its structural and transcriptional functions, ß-catenin is a key factor that acts on both aspects to promote liver tumorigenesis, leading to hepatocellul...

Serum GFAP and Age Accurately Distinguish AQP4 ‐ IgG Positive and Double Seronegative NMOSD From MOGAD After a Recent Attack

BACKGROUND: Serum neurofilament-light chain (sNfL) and glial fibrillary acidic protein (sGFAP) are associated with multiple sclerosis (MS) activity. This study aimed to identify patient- and disease-level determinants of sNfL and sGFAP and to evaluate their ability to support dif...

Astrocytic PI3Kα controls synaptic plasticity and cognitive function via serine metabolism

Astrocytes modulate neuronal activity by gliotransmission and through metabolic regulation, yet the relationship between these functions remains poorly understood. Here we show that phosphatidylinositol 3-kinase (PI3K) signaling in astrocytes controls synaptic plasticity and memo...

Visual Pathways Involvement in Friedreich’s Ataxia Patients Without Macular Impairment

Objectives: Visual Evoked Potential (VEP) abnormalities in Friedreich Ataxia (FA) may result from dysfunction of retinal ganglion cells (RGC), post-retinal visual pathways, or both. Therefore, we aimed to clarify whether in Friedreich Ataxia (FA), abnormal neural conduction is du...
