Dynamic evolution of brain structural patterns in liver transplantation recipients: a longitudinal study based on 3D convolutional neuronal network model.

Objectives: To evaluate the dynamic evolution process of overall brain health in liver transplantation (LT) recipients, we employed a deep learning-based neuroanatomic biomarker to measure longitudinal changes of brain structural patterns before and 1, 3, and 6 months after surgery.

Methods: Because of the ability to capture patterns across all voxels from a brain scan, the brain age prediction method was adopted. We constructed a 3D-CNN model through T1-weighted MRI of 3609 healthy individuals from 8 public datasets and further applied it to a local dataset of 60 LT recipients and 134 controls.

Altered white matter structural connectivity in primary Sjögren's syndrome: a link-based analysis.

Purpose: Cognitive impairment has been revealed in primary Sjögren's syndrome (pSS). However, the underlying white matter structural connectivity (SC) changes have not been studied. This study aimed to investigate the altered white matter brain network in patients with pSS using diffusion tensor imaging (DTI).

[Effects of functional connectivity between anterior cingulate cortex and dorsolateral prefrontal cortex on executive control of attention in healthy individuals].

Objective: To explore the presence of functional connectivity between anterior cingulate cortex (ACC) and dorsolateral prefrontal cortex (DLPFC) during the manipulation of attentional network test (ANT) and its relationship with behavioral performance.

Methods: Functional magnetic resonance imaging was performed on 25 healthy subjects aged 17 - 20 years. And ANT was used as a paradigm.
