introduction maternal and fetal characteristics can be effect on optimism which vary among different cultures and countries. so the aim of this study was to determine prenatal optimism and its relationship with fetal and maternal characteristics in primiparous women. materials and methods this research study was a descriptive cross - sectional. the statistical populations consisted of 240 pregn...

objective: to assess the relationship between maternal uti during pregnancy and neonatal uti. materials and methods: this cross-sectional study included eighty neonates referred to ali-e-asghar hospital, tehran, iran, in 2011. the participants were divided into the study (with diagnosis of uti; n = 40) and the control (without this type of infection; n = 40) groups. the mothers were asked about...

The present report describes a male newborn with a pulsatile structure beneath the sternum. Echocardiography showed common atrium, a single ventricle, mitral atresia, double outlet right ventricle, subpulmonary stenosis, small pulmonary artery branches, and a thin walled ventricular diverticulum suggestive of Cantrell's syndrome. The diverticulum was resected to prevent life threatening events ...

Maternal obesity exerts negative effects on cognitive function and behavior of the offspring. In the present study, we assessed the effects of paternal physical exercise on spatial learning ability in relation with hippocampal neuroplasticity in the rat pups born from the obese maternal rats. There were four experimental groups: paternal nonexercised male pups from normal maternal rats, paterna...

Nanos RNA-binding proteins are required for germline development in metazoans, but the underlying mechanisms remain poorly understood. We have profiled the transcriptome of primordial germ cells (PGCs) lacking the nanos homologs nos-1 and nos-2 in C. elegans. nos-1nos-2 PGCs fail to silence hundreds of transcripts normally expressed in oocytes. We find that this misregulation is due to both del...

The relationship between placental characteristics, including weight and inflammation, and pregnancy outcome was examined as part of a case control study looking into the impact of maternal HIV-1 infection on pregnancy outcome. Cases defined as low birth weight (< 2500g) or stillbirth deliveries, were compared to controls defined as mothers who delivered a live born neonate weighing 2500g or mo...

Steroidogenic factor 1 (SF-1), officially designated NR5A1, is essential for gonadal and adrenal development and for the normal structure of the ventromedial hypothalamus (VMH), as demonstrated by SF-1 knockout mice (SF-1 KO), but much less is known about the possible effects of haploinsufficiency of the SF-1 gene. In the present study, maternal behavior in SF-1 KO heterozygous mice was evaluat...
