BACKGROUND A 40-bp variable number of tandem repeats (VNTR) polymorphism exists in the 15th exon of DAT1, the gene encoding the human dopamine transporter (DAT). Though the VNTR resides in a region encoding the 3' untranslated region (UTR) and does not alter the protein's amino acid sequence, the prevalent 10-repeat variant has shown both linkage and(More)
Depression is a leading cause of morbidity and mortality, and its treatment includes a high percentage of the medications prescribed by physicians. Available antidepressant drugs are safe and effective, but less than half of all patients attain complete remission after therapy with a single antidepressant. Others exhibit partial, refractory or intolerant(More)
OBJECTIVES There are limited data regarding the use of atypical antipsychotic medications in pregnancy. The objectives of the current study were to quantify placental permeability to antipsychotic medications and to document obstetrical outcomes for women taking these agents proximate to delivery. METHOD The authors conducted a prospective observational(More)
The two neuropeptides corticotropin-releasing-factor (CRF) and oxytocin (OT) may produce opposing behavioral effects - elevations of the former have been associated with anxiety and social vigilance and reductions of the latter with reduced social affiliation. We sought to test the hypothesis that, within the primate macaque genus, the more gregarious,(More)
Paroxetine is a potent and selective serotonin reuptake inhibitor (SSRI) with some neuropharmacologic properties unique among this class of compounds. The findings of early in vitro studies demonstrated the potency of paroxetine at inhibiting 5-HT uptake in rat synaptosomes. Paroxetine also has been shown to be a potent and selective inhibitor of the human(More)
BACKGROUND Posttraumatic stress disorder (PTSD) is associated with altered concentrations of stress-related neurohormones, neurotrophins, and neuropeptides in plasma and serum; however, few studies have examined central alterations of these measures in individuals with PTSD. Furthermore, no study to date has evaluated the effects of successful(More)
BACKGROUND The use of antidepressants during pregnancy continues to garner considerable attention, though there are limited investigations that have sought to quantify fetal exposure. METHODS Maternal and umbilical cord sera were collected at delivery from ten women taking nortriptyline and seven taking clomipramine. Placental passage was calculated as(More)
The neurogenesis hypothesis of depression posits (1) that neurogenesis in the subgranular zone of the dentate gyrus is regulated negatively by stressful experiences and positively by treatment with antidepressant drugs and (2) that alterations in the rate of neurogenesis play a fundamental role in the pathology and treatment of major depression. This(More)
Depression is a widespread and serious disorder that afflicts an estimated 13.1 to 14.2 million adults in the United States each year. Even more compellingly, the lifetime prevalence rate of depression in the US has recently been estimated to include 16.2% of adults (21% women, 13% men), or >32.6 million people. There are multiple putative "causes" of(More)
BACKGROUND The purpose of this study was to attain a new landmark in the area of selective serotonin reuptake inhibitor therapy during lactation by establishing a basis for interpreting infant serum concentrations and for minimizing infant exposure in the absence of treatment-emergent side effects. METHOD Breast milk and paired maternal and infant sera(More)
