Background: Histone deacetylase (HDAC) inhibition offers potential anticancer effects across diverse cancers due to HDAC's significant role in cancer development and progression. Consequently, we demonstrated the therapeutic efficacy of the novel HDAC inhibitor, CG-745, in comparison with existing inhibitors such as suberoylanilide hydroxamic acid (SAHA) in non-small cell lung cancer (NSCLC) cells. Methods: CG-745's effect on apoptosis and reactive oxygen species (ROS)-dependent mitochondrial dysfunction was investigated using annexin V assay, MitoSoX, and Western blot in human A549 and H460 cells. Additionally, HDAC expression was analyzed through real-time polymerase chain reaction. We also evaluated the inhibitory effect of CG-745 on epithelial-mesenchymal transition (EMT) induced by transforming growth factor β1 (TGF-β1) via Western blot, scratch analysis, and matrigel invasion analysis. Results: Compared to SAHA, CG-745 inhibited cell viability and mRNA expression of HDACs such as HDAC1, HDAC2, HDAC3, and HDAC8. It also induced apoptosis, ROS, and mitochondrial dysfunction in a concentration-dependent manner. CG-745 reversed EMT triggered by TGF-β1 in A549 and H460 cells, and curtailed the migration and invasion enhanced by TGF-β1. CG-745 has demonstrably inhibited EMT and induced apoptosis in NSCLC cells. Conclusion CG-745 may represent a novel therapeutic strategy for NSCLC treatment.

Purpose: To compare the macular and peripapillary vascular parameters between the primary angle closure suspect (PACS) eyes and normal control eyes using optical coherence tomography angiography (OCTA). Methods: In this retrospective study, 42 PACS subjects and 38 normal individuals are included. Vessel density (VD) and perfusion density (PD) of the macular area and peripapillary area, and fovea avascular zone parameter were analyzed using OCTA and compared between two groups after adjustment for the axial length. Results: There were no statistically significant differences in sex ratio, age, refractive errors and intraocular pressures between both groups. In the peripapillary area, inferior VD and PD in the outer zone were significantly lower in the PACS eyes, while the retinal nerve fiber layer thicknesses were similar between groups (p = 0.032, 0.026). In the macular superficial capillary plexus, inferior VD and PD in the inner zone, inferior VD and PD, nasal VD and PD in the outer zone were significantly lower in the PACS eyes, whereas ganglion cell inner plexiform layer thickness were similar between both groups (all p < 0.005). Conclusions The VDs and PDs of retinal capillaries in PACS eyes, which have no glaucomatous changes in the retinal nerve fiber layer and optic nerve disc, were significantly lower compared to normal eyes.

Purpose: In this study, we aimed to classify an implant system by comparing the types of implant thread shapes shown on radiographs using various Convolutional Neural Networks (CNNs), particularly Xception, InceptionV3, ResNet50V2, and ResNet101V2. The accuracy of the CNN based on the implant site was compared. Materials and Methods: A total of 1000 radiographic images, consisting of eight types of implants, were preprocessed by resizing and CLAHE filtering, and then augmented. CNNs were trained and validated for implant thread shape prediction. Grad-CAM was used to visualize class activation maps (CAM) on the implant threads shown within the radiographic image. Results: Averaged over 10 validation folds, each model achieved an AUC of over 0.96: AUC of 0.961 (95% CI 0.952–0.970) with Xception, 0.973 (95% CI 0.966-0.980) with InceptionV3, 0.980 (95% CI 0.974-0.988) with ResNet50V2, and 0.983 (95% CI 0.975-0.992) with ResNet101V2. Accuracy was higher in the posterior region than in the anterior area in all four models. Most CAMs highlighted the implant surface where the threads were present; however, some showed responses in other areas. Conclusion The CNN models accurately classified implants in all areas of the oral cavity according to the thread shape, using radiographic images.
