Like human fathers, male marmosets help raise their young, yet the ways in which fatherhood influences the brain remain largely unknown.

Amniotic fluid (AF) is a proximal fluid to the fetus containing higher amounts of cell-free fetal RNA/DNA than maternal serum, thereby making it a promising source for identifying novel biomarkers that predict fetal development and organ maturation. Our aim was to compare AF transcriptomic profiles at different time points in pregnancy to demonstrate unique(More)
Obesity is a significant health problem among Veterans who receive care from the Department of Veterans Affairs, as it is for so many other Americans.
