Abstract In recent years, there has been a growing trend toward the digitization of education, highlighting need to understand how different learning modalities impact medical student outcomes. This study analyzes user behavior among students in Microscopic Anatomy, focusing on preferences for digital versus face‐to‐face guided self‐study. A cohort 684 participated Anatomy courses, choosing between and self‐study sessions. Student participation was systematically tracked, capturing detailed...

Embryonic development is a complex process of concurrent events comprising cell proliferation, differentiation, morphogenesis, migration, and tissue remodeling. To cope with the demands arising from these developmental processes, cells increase their nutrient uptake, which subsequently increases metabolic activity. Mitochondria play key role in maintenance metabolism production reactive oxygen species (ROS) as natural byproduct. Regulation ROS by antioxidants critical tightly regulated...

Numerous research results have already pointed towards the negative influence of increased mental stress on educational processes and motivational criteria. It has also been shown that global public health crisis induced by COVID-19 was related to anxiety symptoms elevated levels distress. To holistically elucidate dynamics pandemic-related first-year medical students, associated parameters three different cohorts were measured at beginning restrictions university life in Germany (20/21),...

Previous research work has already demonstrated that both the form of teaching as well different methods directly influence students’ learning experience along with their psychobiological responses at endocrine and autonomic level. Aiming to gain deeper insights into constitution experience, this study examined external factors such generally perceived life stress self-efficacy on immediate in environments. Therefore, a randomized experimental field was conducted which psychological...

Prenatal stress exposure is considered a risk factor for developmental deficits and postnatal behavioral disorders. While the effect of glucocorticoid-associated prenatal has been comprehensively studied in many organ systems, there lack in-depth embryological investigations regarding effects on integumentary system. To approach this, we employed avian embryo as model organism investigated systemic pathologically-elevated glucocorticoid development After standardized corticosterone...

Ninety-five students participated, with heart rate variability (HRV) markers such as RMSSD, pNN50, SDNN, LF/HF ratios used to evaluate responses. Both lecturer-led peer-led simulations significantly reduced HRV markers, indicating heightened...
