BACKGROUND International studies indicate that the median prevalence of psychotic experiences in children is 7%. It has been proposed that environmental stress during pregnancy may affect the neurodevelopment of the foetus and lead to a vulnerability in the child to later stressors and psychopathology. AIM In this study we explore the relationship between environmental stress during pregnancy...

(Co)variance components and genetic parameters were estimated for body weights of a Romosinuano herd located in Sinú Valley, Cordoba, Colombia. Restricted maximum likelihood methods were used with a univariate animal model for birth weight, weaning weight (270 days), 16-month weight (480 days), weaning daily gain, and post-weaning daily gain. Models included random animal direct and maternal ge...

objective: to analyze the trend in maternal mortality ratio in a tertiary care centre and the effect of various maternity schemes on it. materials and methods:  retrospective analysis of all maternal deaths occurring in the guru gobind singh medical college & hospital, faridkot, punjab, india was done from jan 2010 to dec 2012. every maternal death was scrutinized from various aspects like dire...

Intrabreed additive genetic, environmental, and phenotypic variances and covariances for Romosinuano (R) and Zebu (Z), as well as interbreed nonadditive genetic variances and covariances (sire x breed-group-of-dam interactions), for birth weight (BWT), weaning weight (WW), and postweaning gain (GW) were computed using a Romosinuano-Zebu multibreed data set from the Turipaná Experiment Station i...

Mixed model techniques were used to evaluate the importance of cytoplasmic genetic effects on beef cattle performance. Birth weight (BWT), preweaning average daily gain (ADG), weaning weight (WT205), postweaning gain (PG), ultrasonic backfat thickness (FAT) and predicted milk yield (MILK) data were collected in two herds of Hereford cattle located at Plymouth and Raleigh, North Carolina. Cytopl...

INTRODUCTION The incidence of asthma and atopic reactions is increasing worldwide. Previous reports have suggested that maternal exposure to allergens during pregnancy may have potential effects on allergic sensitization in infants. AIM To evaluate the effects of maternal exposure to environmental allergens during pregnancy on in-utero sensitization. MATERIAL AND METHODS Two hundred mothers...

Maternal condition during pregnancy is known to influence fetal viability. Recently, primatologists have suggested that certain characteristics of the fetus may influence maternal condition as well. For example, among captive pigtailed macaques (Macaca nemestrina) mothers of female infants may be a t greater risk of injury during their pregnancies than mothers of male infants. Analysis of the r...

In many animal species, the amount of care provided by parents is determined through a complex interaction of offspring signals and responses by parents to those signals. As predicted by honest signaling theory, we show that in the burrower bug, Sehirus cinctus, maternal provisioning responds to experimental manipulations of offspring condition. Despite this predicted environmental influence, w...

If maternal expressed emotion is an environmental risk factor for children's antisocial behavior problems, it should account for behavioral differences between siblings growing up in the same family even after genetic influences on children's behavior problems are taken into account. This hypothesis was tested in the Environmental Risk Longitudinal Twin Study with a nationally representative 19...

Perinatal maternal smoking exposure (PMSE) is one of the major environmental risk factors encountered by the fetus. PMSE is usually associated with adverse pregnancy outcomes that may manifest at different stages of life. Nevertheless, fetal growth restriction is the most common smoking-induced side effect. PMSE induces changes in the maternal multiple organ systems. These alterations may affec...
