Stressed male mice can pass down their behaviors to their offspring via alterations in their sperm's DNA, a new study reports.
A new study of male guppies reveals behaviors affected by methylphenidate hydrochloride (MPH), an active ingredient in common ADHD medications, can be passed along to future generations.
Researchers explore the link between childhood trauma and the increased risk of developing mental and physical health problems as adults.
Immune cells in the uterus and placenta of stressed pregnant mice were not activated, but researchers found increased levels of inflammation in the developing fetal brain. Additionally, prenatal stress led to reductions in gut microbial strains and functions, especially in those linked to inflammation.
From impairing nervous system function and changing bacterial communities in the microbiome to increasing oxidative stress and inflammation, researchers report on the ways in which exposure to chemical pollution harms the body.
Researchers used epigenetic modulators to reduce the damage done by stress to neuroplasticity. Findings reveal acute intervention in epigenetic mechanisms produced antidepressant effects more rapidly than conventional medications.
