The EX and LA ameliorated cholesterol-induced changes in serum OC (0.857 ±0.160 ng/mL and 1.103 ±0.356 ng/mL, respectively) and CTX (7.735 ±1.045 ng/mL and 8.128 ±1.106 ng/mL, respectively). There was a significant decrease in femoral BMD in CHOL group (0.429 ±0.11 g/cm² vs 0.449 ±0.020 g/cm²). The EX and LA ameliorated those changes (0.458 ±0.016 g/cm² and 0.449 ±0.021 g/cm², respectively). The microCT revealed increased bone volume ratio (BV/TV) and trabecular thickness (Tb.Th.) in the CHOL+EX group. Cornus mas L. inhibited bone resorption and stimulated bone formation, thereby preventing the development of cholesterol-induced osteoporosis.

The paper presents an analysis of opinions concerning the use of stem cells (SCs), using tools developed in the field of moral psychology. To determine the factors that affect beliefs regarding the status of SCs and to evaluate the impact of these factors. The paper investigated whether factors of a moral nature prevail over the knowledge that makes it possible to use SCs in practice. The analysis of psychological perception is based on a study carried out on a group of 172 Polish and 161 English-speaking first-year medical students. The study was conducted between 2005 and 2007, and in 2019 at the Poznan University of Medical Sciences (Poland). Knowledge is not the main factor that differentiates approaches towards the use of SCs. The importance of religion in the lives of the respondents has a significant impact on the perception of the use of SCs, and is associated with indications of ethically saturated terms. Focusing on the usefulness of cells is associated with lesser significance of religion and greater value placed on scientific kn
