UGLS: an uncertainty guided deep learning strategy for accurate image segmentation.

Accurate image segmentation plays a crucial role in computer vision and medical image analysis. In this study, we developed a novel uncertainty guided deep learning strategy (UGLS) to enhance the performance of an existing neural network (i.e.

Semi-supervised image segmentation using a residual-driven mean teacher and an exponential Dice loss.

Semi-supervised segmentation plays an important role in computer vision and medical image analysis and can alleviate the burden of acquiring abundant expert-annotated images. In this paper, we developed a residual-driven semi-supervised segmentation method (termed RDMT) based on the classical mean teacher (MT) framework by introducing a novel model-level residual perturbation and an exponential Dice (eDice) loss. The introduced perturbation was integrated into the exponential moving average (EMA) scheme to enhance the performance of the MT, while the eDice loss was used to improve the detection sensitivity of a given network to object boundaries.

LncRNA DDX11-AS1 Exerts Oncogenic Roles in Glioma Through Regulating miR-499b-5p/RWDD4 Axis.

Background: Long noncoding RNAs (lncRNA) exert essential functions during tumorigenesis. However, how lncRNAs participate in glioma development remains poorly researched. This study aimed to determine how DDX11-AS1 affects glioma progression.

Case-control pharmacogenetic study of HCN1/HCN2 variants and genetic generalized epilepsies.

Epilepsy is a common complex neurological disorder, and some forms are resistant to drug treatment. The HCN1/HCN2 genes encode hyperpolarization-activated cyclic nucleotide-gated channels, which play important roles in the electrophysiology of neurons. We investigated the association between HCN1/HCN2 variants and drug resistance or the risk of genetic generalized epilepsies (GGEs).

CCR7 Mediates TGF-β1-Induced Human Malignant Glioma Invasion, Migration, and Epithelial-Mesenchymal Transition by Activating MMP2/9 Through the Nuclear Factor KappaB Signaling Pathway.

Chemokine receptor 7 (CCR7) has emerged as an inducer of invasion, migration, and epithelial-mesenchymal transition (EMT) in cancer. In this research, human malignant glioma cells were stimulated with transforming growth factor beta 1 (TGF-β1) and siCCR7. The data show that CCR7 mediates TGF-β1-induced EMT, migration, and invasion in U251 and U87 cells and that these effects of TGF-β1 were reversed by treatment with siCCR7 or a CCR7 neutralizing antibody.

Theoretical observation on diagnosis maneuver for benign paroxysmal positional vertigo.

Conclusion: To make a comprehensive analysis with a variety of diagnostic maneuvers is conducive to the correct diagnosis and classification of BPPV.

Objective: Based on the standard spatial coordinate-based semicircular canal model for theoretical observation on diagnostic maneuvers for benign paroxysmal positional vertigo (BPPV) to analyze the meaning and key point of each step of the maneuver.

Materials And Methods: This study started by building a standard model of semicircular canal with space orientation by segmentation of the inner ear done with the 3D Slicer software based on MRI scans, then gives a demonstration and observation of BPPV diagnostic maneuvers by using the model.

[Long-term effect and safety of non-occlusive intra-vas device for male contraception].

Objective: To assess the long-term effect and safety of non-occlusive intra-vas device (IVD) for male contraception in comparison with no-scalpel vasectomy (NSV).

Methods: We conducted a follow-up investigation on 100 males who had received IVD and another 50 who had undergone NSV 6 years before. We compared the rates of sperm absence and complications between the two groups.
