Domain-guided conditional diffusion model for unsupervised domain adaptation.

Limited transferability hinders the performance of a well-trained deep learning model when applied to new application scenarios. Recently, Unsupervised Domain Adaptation (UDA) has achieved significant progress in addressing this issue via learning domain-invariant features. However, the performance of existing UDA methods is constrained by the possibly large domain shift and limited target domain data.

Disruption of extracellular matrix and perineuronal nets modulates extracellular space volume and geometry.

Extracellular matrix (ECM) is a network of macromolecules which has two forms - perineuronal nets (PNNs) and a diffuse ECM (dECM) - both influence brain development, synapse formation, neuroplasticity, CNS injury and progression of neurodegenerative diseases. ECM remodeling can influence extrasynaptic transmission, mediated by diffusion of neuroactive substances in the extracellular space (ECS). In this study we analyzed how disrupted PNNs and dECM influence brain diffusibility.

Performance of ChatGPT in French language analysis of multimodal retinal cases.

Purpose: Prior literature has suggested a reduced performance of large language models (LLMs) in non-English analyses, including Arabic and French. However, there are no current studies testing the multimodal performance of ChatGPT in French ophthalmology cases, and comparing this to the results observed in the English literature. We compared the performance of ChatGPT-4 in French and English on open-ended prompts using multimodal input data from retinal cases.

Comparative effectiveness of interventions for the prevention and treatment of perinatal depression: A systematic review and network meta-analysis.

Background: Several interventions have been investigated addressing perinatal depression; however, interventions have not been compared using both direct and indirect evidence. This study compared the relative effectiveness of all interventions that prevent depression (objective 1) or treat depression symptoms (objective 2) in perinatal women.

Methods: Eight databases searched from their inception to March 2024.
