The interaction between third molars and surrounding periapical tissues in mandibular stress distribution during high-impact trauma: a finite element study.

Background: The presence of mandibular third molars has been associated with the risk of mandibular fractures, highlighting the need for comprehensive studies considering the interaction with other mandibular structures. This study investigates how mandibular third molars and neighboring tissues can influence the structural fragility of the mandible using finite element analysis.

Material And Methods: A finite element analysis study following the guidelines proposed by RIFEM 1.

Integration of Copper Toxicity Mechanisms in : Advancing Insights at Environmentally Relevant Concentrations.

This work aimed to characterize the impact of copper (Cu), at environmentally relevant concentrations, using the freshwater microalga . Algae were incubated with 33 or 53 µg/L Cu, in OECD medium, and toxic impacts were evaluated over 72 h, using different cellular and biochemical biomarkers. The exposure to 33 µg/L Cu had an algistatic effect: slowing growth and reducing algal population (53%, at 72 h) without compromising the cell membrane.

Performance and quality of eggs of laying hens fed with Moringa Oleifera leaf flour.

The objective of this study was to evaluate the performance of commercial laying hens fed with different levels of Moringa oleifera leaf meal in their diet. For this purpose, 150 laying hens of the Dekalb White lineage, at 62 weeks of age, and with an initial average weight of 1.458 kg ± 8.
