A Possible Brain Mechanisms Behind COVID-19 Delirium

Brain cells exposed to blood taken from COVID-19 patients with delirium showed a decrease in neurogenesis and an increase in cell death. The findings also indicate a key role for cytokines produced in the immune system during infection and shed light on the molecular mechanisms of COVID-19 related delirium.

‘Love Hormone’ Oxytocin Could Mend a Broken Heart

Oxytocin, a hormone connected with bonding and love, could help to heal damage following a heart attack. Researchers found oxytocin stimulates stem cells from the heart's outer layer and migrates into the middle layer where it develops into muscle cells that generate heart contractions. This could be used to promote the regeneration of heart cells following a heart attack.
