Article Abstract
The dynamics of active oxygen forms (AOF) generation in rat thymocytes 50 min after treatment with 0.1 and 0.5 mM H2O2 was estimated with the use of fluorescent probe DCFDA. Both enhanced AOF generation, which was dependent on H2O2 concentration, and glutathione peroxidase and superoxide dismutase activation, followed by a decrease of thymocytes viability were demonstrated. Preincubation of cells with 10(-5) M fullerene C60 was shown not only to prevent H2O2--induced AOF generation but to increase viability of H2O2-treated thymocytes at more prolonged time period. The data obtained indicate to fullerene C60 ability to prevent oxidative stress in thymocytes.

The skull base exhibits numerous morphologic variants, some of which are uncommon and hold clinical significance. The imaging report presents a rare instance of multiple skull base variants identified incidentally through a computed tomography (CT) scan of a 53-year-old female patient. The findings revealed a bilateral partial atlanto-occipital fusion (AOF), an absent C1 posterior arch, and a complete bilateral ossification of the caroticoclinoid and anterior interclinoid ligaments in the form of bars (CCBs and AIBs).

Using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), the active ingredients and potential targets of AOF-SR were screened and its molecular mechanisms were investigated through molecular docking, molecular dynamics simulations, and experimental validation. The db/db mice were randomly divided into four groups: model group, low-dose AOF-SR group, high-dose AOF-SR group, and canagliflozin group.

Artificial intelligence (AI) can transform drug discovery and early drug development by addressing inefficiencies in traditional methods, which often face high costs, long timelines, and low success rates. In this review we provide an overview of how to integrate AI to the current drug discovery and development process, as it can enhance activities like target identification, drug discovery, and early clinical development. Through multiomics data analysis and network-based approaches, AI can help to identify novel oncogenic vulnerabilities and key therapeutic targets.

Aim: The study aimed to evaluate the quality and readability of Arabic-language web-based online information regarding surgical third molar extraction.
Methods: In this observational web-based analytical study, the top 150 Arabic search results for surgical wisdom tooth extraction were collected from Google, Yahoo, and Bing. The quality of the websites was evaluated using the DISCERN tool and the Journal of American Medical Association (JAMA) guidelines for online content analysis.
SC-AOF: A Sliding Camera and Asymmetric Optical-Flow-Based Blending Method for Image Stitching.

Parallax processing and structure preservation have long been important and challenging tasks in image stitching. In this paper, an image stitching method based on sliding camera to eliminate perspective deformation and asymmetric optical flow to solve parallax is proposed. By maintaining the viewpoint of two input images in the mosaic non-overlapping area and creating a virtual camera by interpolation in the overlapping area, the viewpoint is gradually transformed from one to another so as to complete the smooth transition of the two image viewpoints and reduce perspective deformation.
