Introduction: Delaire's architectural analysis is a tool used in the maxillofacial field. Its use requires identifying landmarks teleradiographically in order to map appropriate lines dependent on these points. We studied the elasticity of the analysis.
Material And Method: The C0 line technique was used to vary individually the spatial position of specific landmarks and lines. The consequences on the position of the Me point and the slope of the occlusal plane were tabulated.
Results: Modifying the special position of the studied landmarks did not affect the final map drawn by the analysis, proving that Delaire's analysis has a certain degree of elasticity. It was noted however that the F4 line might be the determining factor.
Discussion: After the mathematical and geometrical demonstration, the question is raised of whether or not there is an ideal and single craniofacial architecture for a given patient, taking into consideration the elasticity of the analysis and the problem of positioning the F4 line.

Objective: TRIB3 has been confirmed to participate in and regulate biological metabolic activities in head and neck tumors such as nasopharyngeal carcinoma and oropharyngeal carcinoma, so the purpose of this study was to explore whether there is a correlation between TRIB3 and Laryngeal Squamous Cell Carcinoma (LSCC) and to preliminarily explore the biological characteristics of TRIB3 in LSCC.
Methods: TRIB3 expression in the LSCC was analyzed based on The Cancer Genome Atlas (TCGA) database. CCK-8 assay, Colony Formation Assay, wound healing assay, and Transwell assay were performed to investigate the roles of TRIB3 in the proliferation, invasion and metastasis of LSCC.

The protozoan parasite Neospora caninum is an important cause of abortion in cattle. Infection occurs horizontally by ingestion of oocysts shed by canids or vertically, from an infected dam to the foetus, and may result in abortion, stillbirth, or the birth of subclinically infected offspring. We estimated the occurrence of N.

Dealing with radioactive waste, particularly from various industrial processes, poses significant challenges. This paper explores the use of lithium aluminate borate (Li-Al-B) glass matrix as an alternative method for immobilizing radioactive waste, focusing specifically on waste generated in tin smelting industries, known as tin slag. The study primarily concentrates on transforming tin slag, a byproduct abundant in Natural Occurring Radioactive Material (NORM), into a stable and safe form for disposal.

Skipping represents a training alternative to running due to its lower knee contact forces and higher whole-body metabolic cost. The increased metabolic cost of skipping is associated with a higher vertical center-of-mass (COM) displacement during the support and flight phases of the skipping hop compared to running. However, skipping has lower muscle force impulses than running.

In the medical field, endoscopic video analysis is crucial for disease diagnosis and minimally invasive surgery. The Endoscopic Foundation Models (Endo- FM) utilize large-scale self-supervised pre-training on endoscopic video data and leverage video transformer models to capture long-range spatiotemporal dependencies. However, detecting complex lesions such as gastrointestinal metaplasia (GIM) in endoscopic videos remains challenging due to unclear boundaries and indistinct features, and Endo-FM has not demonstrated good performance.
