Background And Objectives: Temporal lobe epilepsy (TLE) is commonly associated with mesiotemporal pathology and widespread alterations of gray and white matter structures. Evidence supports a progressive condition, although the temporal evolution of TLE is poorly defined. In this ENIGMA-Epilepsy study, we aim to investigate structural alterations in gray and white matter across the adult lifespan in patients with TLE by charting both gray and white matter changes and explore the covariance of age-related alterations in both compartments.

Nine Tn-based cancer vaccines were designed and synthesized using Mincle agonists as a carrier to elucidate the structure-immunogenicity relationships of Mincle-dependent vaccines. The Immunological evaluation showed that the immune response levels were significantly influenced by the acyl chains of trehalose, coupling site of antigen and carriers, antigen copy number, and coupling mode of acyl chains and trehalose. Notably, installing the antigen onto the lipid chains of the carrier could also effectively improve the immunogenicity.

Article Synopsis
  • EEG-based emotion recognition analyzes neural activity to predict emotions but faces challenges due to the variability of data across subjects in time, frequency, and spatial domains.
  • To tackle these issues, a new model called Temporal-Spectral Graph Convolutional Network (TSGCN) is introduced, which uses a Minimum Category Confusion loss to align subjective and predefined emotional labels.
  • Experiments show that TSGCN outperforms existing methods in emotion recognition and exhibits high robustness, largely due to its unique approach and the integration of Deep and Shallow feature Dynamic Adversarial Learning for cross-subject adaptation.

Attentional control, guided by top-down processes, enables selective focus on pertinent information, while habituation, influenced by bottom-up factors and prior experiences, shapes cognitive responses by emphasizing stimulus relevance. These two fundamental processes collaborate to regulate cognitive behavior, with the prefrontal cortex and its subregions playing a pivotal role. Nevertheless, the intricate neural mechanisms underlying the interaction between attentional control and habituation are still a subject of ongoing exploration.

Article Synopsis
  • Temporal lobe epilepsy (TLE) is mainly a limbic network disorder characterized by unilateral hippocampal issues and has been studied using structural MRI for brain grey matter changes.
  • The study utilized the ENIGMA-Epilepsy dataset to compare grey matter asymmetry and atrophy in TLE patients versus healthy controls, finding distinct patterns: atypical asymmetry showed a temporo-limbic signature, while atrophy appeared diffuse and bilateral.
  • Results indicated that cortical atrophy correlates with factors like disease duration and age at seizure onset, while asymmetry levels did not, suggesting that these two measures capture different but complementary aspects of TLE pathology.
