Student Performance and Perceptions of Flipped Classrooms and Small Group Discussions as Teaching Tools in Practical Anatomy.

Introduction A quasi-experimental study was conducted to assess students' attitudes toward the flipped practical classroom and evaluate its effectiveness in teaching practical anatomy. Methods Two survey questionnaires were developed: the first assessed students' attitudes toward flipped practical classrooms, while the second focused on the obstacles and difficulties students might encounter in this learning environment. Results We found that students rated flipped learning significantly higher compared to other teaching methods, particularly in terms of the quality of learning materials, enhancement of learning skills, engagement and understanding of anatomy topics, and problem-solving abilities.

Impact of photodynamic therapy as an adjunct to non-surgical periodontal treatment on clinical and biochemical parameters among patients having mild rheumatoid arthritis with periodontitis.

Purpose: To evaluate the efficacy of photodynamic therapy (PDT) as an adjunct to non-surgical periodontal therapy on the clinical periodontal and biochemical parameters among patients with rheumatoid arthritis (RA) having periodontitis.

Methods: A total of 50 RA patients with periodontitis were included. The subjects were equally divided into two groups: Group A - scaling and root planning (SRP) + PDT; Group B - SRP only, respectively.

Application of in-plant control measures in some Egyptian micro-scale dairy enterprises and its impact on heavy metal contents of their products.

Egypt is encouraging micro-scale enterprises as proved to be one of the most important reasons of economic growth. Most of the annual milk production is processed in micro-scale dairy enterprises located in squatter areas with high health risks and negative environmental impact. The aim of this study was to assess the effectiveness of in-plant control measures in controlling lead and cadmium levels in dairy products from nine Egyptian micro-scale enterprises.
