Early gestation dexamethasone programs enhanced postnatal ovine coronary artery vascular reactivity.
Excessive exposure of the fetus to maternally derived corticosteroids has been linked to the development of adult-onset diseases. To determine if early gestation corticosteroid exposure alters subsequent coronary artery reactivity, we administered dexamethasone (0.28 mg.kg(-1).day(-1)) to pregnant ewes at 27-28 days gestation (term being 145 days). Vascular responsiveness was assessed in endoth...
Prenatal marijuana exposure is associated with adverse perinatal effects. Very little is known about the effect of postnatal marijuana exposure on infant development. Postnatal exposure can result from maternal use of marijuana during lactation. Delta-9-tetrahydrocannabinol (THC) transfers and concentrates in the mother's milk and is absorbed and metabolized by the nursing infant. The present s...
background: mothers are highly vulnerable to depression within the first year after childbirth. approximately 10-20% of mothers suffer from depression during this period, and half of these women with symptoms of prominent postpartum depression (ppd) remain undiagnosed. the edinburgh postnatal depression scale (epds) is the most widely applied screening instrument for ppd evaluation. in this stu...
background: in recent years concerns have been raised about human reproductive disorders, specially the effects of environmental factors on human fertility and pregnancy outcome. therefore, the present study was designed to assess the effects of maternal caffeine consumption on ovarian follicles development in rat offspring. methods: 60 pregnant female rats were randomly divided into a control ...

Exposure to environmental tobacco smoke (ETS) in the early postnatal period has been associated with several diseases; however, little is known about the brain effects of ETS exposure during this critical developmental period or the long-term consequences of this exposure. This study investigated the effects of the early postnatal ETS exposure on both reference and working memory, synaptic prot...
