A total of 124 children with ADHD were randomly allocated to two groups: 64 received medication treatment alone (M), including atomoxetine (ATX) and methylphenidate (MPH); 60 received targeted cognitive training combined with medication (TCT + M), including TCT + ATX and TCT + MPH.

ICs with significant group differences from the same index across two modalities were considered joint group-discriminative ICs. Joint ICs reveal cross-modal neurophysiological mechanisms of GMV-FA. A modal-specific group-discriminative IC is defined as a component that shows significant group difference only in unimodal, revealing specific neurophysiological mechanisms of GMV/FA. The relationship between neuroimaging findings and clinical characteristics was assessed. We also investigated the spatial correlations between the joint and modality-specific ICs and neurotransmitter profiles.</p><p><strong>Results: </strong>Compared to HCs, patients with UC showed one joint group-discriminating component (GMV_IC4-FA_IC4) mainly in the default mode network, thalamus, corpus callosum, corona radiata, fornix, posterior thalamic radiation, middle cerebellar peduncle, and corticospinal tract as well as one modality-specific group-discriminating component (FA_IC5). The loadings of GMV_IC5 were significantly negatively correlated with platelet levels in UC. Moreover, significant associations between the abnormalities of GMV_IC4 and the dopamine and gamma-aminobutric acid (GABAa) system, between the abnormalities of FA_IC4 and the dopamine, GABAa, acetylcholine, and glutamate system, and between the abnormalities of FA_IC5 and dopamine and serotonin systems were found in this study.</p><p><strong>Conclusions: </strong>This study suggested the complex interplay between structural alterations and associated neurotransmitter changes in neural systems subserving emotion dysregulation and visceral sensory processing in UC patients. The identified covarying GMV-FA complements previous findings of structural abnormalities. Furthermore, these findings provided novel insights into the neuropathological mechanisms and potential therapeutic targets of UC.</p>","PeriodicalId":9188,"journal":{"name":"BMC Medicine","volume":"23 1","pages":"345"},"PeriodicalIF":7.0,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12150476/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144257385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, preeclampsia-associated changes in platelet gene expression and activation at the maternal-foetal interface remain unknown. Moreover, aspirin nonresponsiveness in high-risk pregnancies underscores the need for low-cost biomarkers to identify nonresponders. Nevertheless, the changes of platelet indices in women who develop preeclampsia despite aspirin prophylaxis have not yet been evaluated. In this study, we aimed to investigate the changes in platelet indices associated with aspirin nonresponsiveness, activation state and transcriptional landscape in preeclampsia.</p><p><strong>Methods: </strong>Platelet indices were compared between aspirin-responsive and nonresponsive women. Logistic regression analysis was performed to determine the associations between platelet indices and aspirin nonresponsiveness.

Colocalization analysis of CD42b and CD62P revealed that the preeclamptic placenta and decidua presented significant platelet activation. RNA-seq analysis revealed a total of 20, 618 and 1819 transcripts in the peripheral blood, placental villous and decidua of preeclamptic women, respectively. Functional analysis revealed that the PI3K-Akt and Wnt signalling pathways were significantly enriched in the placental villous and decidua of preeclamptic patients, respectively.
