OBJECTIVE Analyze indications and type of prenatal diagnostic procedures performed. METHOD This retrospective audit was conducted at a dedicated fetal medicine center in Petaling Jaya. All invasive prenatal diagnosis procedures performed from 2003 up until 2010 (amniocentesis, chorionic villous sampling and fetal blood sampling) were analyzed. RESULT A total of 1560 invasive prenatal diagno...
Neonatal studies suggest elevated arousal can negatively influence perceptual and cognitive processes during early development. The authors explored this issue during the prenatal period by pharmacologically elevating physiological arousal in bobwhite quail (Colinus virginianus) embryos during exposure to a maternal call, then assessing preference for the familiar call following hatching. Embry...
This study investigated the relationships between pre- and early post-natal maternal depression and their changes with frontal electroencephalogram (EEG) activity and functional connectivity in 6- and 18-month olds, as well as externalizing and internalizing behaviors in 24-month olds (n = 258). Neither prenatal nor postnatal maternal depressive symptoms independently predicted neither the fron...
prenatal stress in rats results in structural, physiological and behavioral alterations that persist in adulthood. serotonin (5-ht) is an important neurotransmitter known to be involved in these prenatal stress-induced behavioral alterations. the aim of the study was to investigate the effects of interrupted synthesis of 5-ht and immobilization stress during different gestational period on brai...
This study employed an in situ hybridization technique to compare the cellular expression of oestrogen receptor (ER) subtypes, ER and , in the female reproductive organ of the rat during prenatal and postnatal periods. Diffuse signals of ER and mRNAs were co-expressed in the foetal ovary; they were weak and inconsistent before onset of gonadal differentiation, but increased in intensity with ag...
This study intended to present a systematic review to analyze the empirical studies published between 1998 and 2003 about maternal anxiety in the prenatal and postnatal periods, focusing on pre-term and term births. Nineteen studies were found; six of which evaluated maternal anxiety in the prenatal period, 12 studies evaluated anxiety in mothers in the postnatal period and only one study evalu...
