Effect of changing the internal structure on the mechanical properties of three-dimensional-printed custom tray material: An in vitro study.

The main challenges to the widespread clinical application of three-dimensional (3D)-printed customized trays include cost and time limitations. This study examined how changing the internal structure of 3D-printed materials used for customized trays affects flexural strength (FS), flexural modulus (FM), manufacturing time, and material weight. Specimens (64 × 10 × 3.

Investigation of the sense of school belonging and sportspersonship behavior of students playing traditional children's games.

The purpose of this study is to examine the sense of school belonging and sportspersonship behaviors of students who participate in traditional children's games. The research was designed using a quasi-experimental model with a pre-test and post-test control group and was conducted over a period of 16 weeks. The study group consisted of a total of 1871 students, including 1379 middle school and 492 high school students, continuing their education in Eskil, Aksaray during the 2023-2024 academic year.

Evaluation of the Mechanical Properties of Provisional 3DPrinted Resin After Repair with Different Materials: An In-Vitro Study.

Purpose: To evaluate the mechanical properties of the 3D printed provisional restoration material that was repaired using different materials.

Material And Methods: The bar specimens have been manufactured using three-dimensional printing technology in accordance with the ISO 10477:2020 standards and divided into 5 groups randomly. For repair material application and replacement on the standardized silicone mold, the test specimens were ground at the center by 1x2x2 mm.

Mechanistic modeling of cell viability assays with lineage tracing.

Data from cell viability assays, which measure cumulative division and death events in a population and reflect substantial cellular heterogeneity, are widely available. However, interpreting such data with mechanistic computational models is hindered because direct model/data comparison is often muddled. We developed an algorithm that tracks simulated division and death events in mechanistically detailed single-cell lineages to enable such a model/data comparison and suggest causes of cell-cell drug response variability.
