An in vitro system for measuring genotoxicity mediated by human CYP3A4 in Saccharomyces cerevisiae.

P450 activity is required to metabolically activate many chemical carcinogens, rendering them highly genotoxic. CYP3A4 is the most abundantly expressed P450 enzyme in the liver, accounting for most drug metabolism and constituting 50% of all hepatic P450 activity. CYP3A4 is also expressed in extrahepatic tissues, including the intestine.

Prevention of postpartum traumatic stress in mothers with preterm infants: manual development and evaluation.

Premature birth has been associated with multiple adverse maternal psychological outcomes that include depression, anxiety, and trauma as well as adverse effects on maternal coping ability and parenting style. Infants who are premature are more likely to have poorer cognitive and developmental functioning and, thus, may be harder to parent, both as infants and as they get older. In response to these findings, a number of educational and behavioral interventions have been developed that target maternal psychological functioning, parenting, and aspects of the parent-infant relationship.

Neonatal CSF oxytocin levels are associated with parent report of infant soothability and sociability.

Oxytocin (OT) has been linked to social behavior in rodents, non-human primates, and adult humans, but almost nothing is known about brain OT activity in human newborns or its impact on social development. To better understand the role of OT biology in human social functioning, a multi-disciplinary, longitudinal study was conducted. Cerebral spinal fluid (CSF) OT levels from 18 human neonates were evaluated and examined in relationship to social-seeking behavior at term, at 3 months, and at 6 months of age.
