Mesenchymal stromal/stem cells from perinatal sources: biological facts, molecular biomarkers, and therapeutic promises.

The use of mesenchymal stem cells (MSCs) from perinatal tissue sources has gained attention due to their availability and lack of significant ethical or moral concerns. These cells have a higher proliferative capability than adult MSCs and less immunogenic or tumorigenesis risk than fetal and embryonic stem cells. Additionally, they do not require invasive isolation methods like fetal and adult MSCs.

Baevsky's Stress Index as a Sensitive Indicator for Biofeedback Efficacy in Medical Students: a Pilot Study.

Medical students often encounter stress, impacting their mental health and academic achievements. Biofeedback is an efficient stress management tool, but its efficacy in medical students is still poorly studied. A key biofeedback metric is heart rate variability (HRV), which detects stress through changes in autonomic nervous system activity.
