Rationale And Objectives: To evaluate the value of artificial intelligence (AI) assisted diagnostic system in reconstructing axial lumbar disc CT images and diagnosing lumbar disc herniation.
Materials And Methods: 440 patients with lumbar disc herniation were included, with 400 cases of spiral data (320 training, 40 validations, and 40 testing) and 40 cases of axial data (testing). V-Net was used to reconstruct the axial lumbar disc images.
Purpose: This study investigated whether abnormal cerebral activity observed in adolescents and adults with ADHD also occurs in children during the early developmental stages of executive function.
Methods: The study included 52 children with ADHD aged 4.0-9.
Objective: To explore whether the motor developmental level is associated with the attention deficit/hyperactivity disorder (ADHD) symptoms severity reported by parents in preschool children.
Methods: Preschool children aged 4-6 years old with the chief complaint of reported inattention or hyperactivity by kindergarten teachers or parents were recruited in this study. All participants were consulted by at least one experienced developmental behavior pediatrician, according to DSM-V diagnostic criteria of ADHD.
Objective: This study aimed to investigate the value of radiomics analysis in the precise diagnosis of triple-negative breast cancer (TNBC) based on breast dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and apparent diffusion coefficient (ADC) maps.
Methods: This retrospective study included 326 patients with pathologically proven breast cancer (TNBC: 129, non-TNBC: 197). The lesions were segmented using the ITK-SNAP software, and whole-volume radiomics features were extracted using a radiomics platform.
Accumulated functional magnetic resonance imaging (fMRI) and electroencephalography evidence indicate that numerosity is first processed in the occipito-parietal cortex. fMRI evidence also indicates right-lateralized processing of numerosity, but there is no consistent evidence from event-related potential (ERP) studies. This study investigated the ERP of numerosity processing in the left, right, and bilateral visual fields.

Studies have shown the close association between subitizing and math performance, however, the mechanism for the association remains unclear. The present study was conducted to investigate whether form perception assessed on a serial figure matching task is a potential non-numerical mechanism between subitizing ability and math performance.

Methods: Patients with CD (n = 198) and normal controls (n = 123) underwent quantitative computed tomography (QCT) examination of lumbar vertebrae 1-3 (L1-3). The BMD and bone geometric parameters were measured and outputted by QCT post-process software.
It remains unclear whether human species exhibits sexual dimorphism in brain activities, and how the dimorphisms associated with sex-characterized behaviors. Here, in a large dataset from Human Connectome Project, we investigated sex differences of resting-state network structure by using local and global network graph similarity analysis. The "typical male" and "typical female" resting-state networks were highly similar.

This study aimed to investigate the relevant factors affecting the quality of life (QoL) in euthyroid HT patients after LT4 treatment.
Methods: In this case-control study, 133 participants with HT were included.
Obesity is closely associated with low-bone-mass disorder. Discoidin domain receptor 2 (DDR2) plays essential roles in skeletal metabolism, and is probably involved in fat metabolism. To test the potential role of DDR2 in fat and fat-bone crosstalk, Ddr2 conditional knockout mice (Ddr2) were generated in which Ddr2 gene is exclusively deleted in adipocytes by Adipoq Cre.

We examined the physiological response of 1-year-old branches of 37 Xinjiang wild walnut germplasm resources in Gongliu wild walnut forest under cold temperatures (-20 ℃ and 4 ℃) for 12 hours, compared the responses with that of . The relative conductivity (REC), free proline (PRO), soluble sugar (SS), malondialdehyde (MDA) content and peroxidase (POD) activity were measured in an artificial climate chamber by simulating spring low temperature. Subordinate function and principal component analysis were used to evaluate the physiological response of walnut germplasm to low temperature.

Methods: We constructed DL models with AlexNet, VGGNet, and ResNet. The models were trained separately with transfer learning.
Graves' disease (GD) occurs due to an autoimmune dysfunction of thyroid gland cells, leading to manifestations consistent with hyperthyroidism. Various studies have confirmed the link between autoimmune conditions and changes in the composition of intestinal microbial organisms. However, few studies have assessed the relationship between the GD and the changes in intestinal microbiota.
View Article and Find Full Text PDFEvidence from cognitive neuroscience indicates that subcortical regions, especially the pulvinar region of the thalamus, are involved in semantic processing. In the current study, graph-based methods were used to investigate whether a cortical-subcortical network is involved in vocabulary processing. In addition to traditional resting-state functional connectivity (rsFC) analysis between local brain areas, we applied a novel method to validate the interaction between semantic network hubs and the pulvinar.
View Article and Find Full Text PDFTheranostic nanosystems encompassing imaging reagents and therapeutic genes are promising for concurrent tumor diagnosis and gene therapy. In this work, we developed bioresponsive gadolinium (Gd)-based nanopolyplexes (denoted as Gdplexes) for tumor theranostic applications. Gdplexes were generated by a hierarchical assembly method involving the neutralization of DNA with a Gd-chelated bioreducible cationic polyurethane (termed as GdCPUA), which was followed by condensation of DNA with a cationic dextran conjugate (DP800).

Study Design: Based on data from Chinese nationwide surveys of family planning and reproductive health undertaken in 1988, 1997, 2001 and 2006, this study uses a multinomial logit model to analyze changes in, regional differences in and determinants of contraceptive behaviors during this period.
Results: The overall prevalence of contraceptive use among married women aged 15-49 years changed little during these 20 years, holding steady at about 90%.
