The imprinted Igf2 gene is active only on the paternal allele in most tissues. Its imprinting involves a cis-acting imprinting-control region (ICR) located upstream of the neighboring and maternally expressed H19 gene. It is thought that differential methylation of the parental alleles at the ICR is crucial for parental imprinting of both genes. Differentially methylated regions (DMRs) have als...
To further elucidate the possible effects of paternal alcohol exposure on fetal and post-natal development, Lee et al. conducted an experimental animal study from which potential transgenerational consequences of paternal alcohol exposure on mouse offspring were explored. The authors concluded that paternal alcohol consumption likely poses some risk to those developing offspring. However, the a...
Background and Aim: Maternal- fetal attachment (MFA) plays an important role in the health of pregnant women and their unborn babies. The purpose of the present study was to compare MFA in pregnant women regarding specific factors influencing maternal– fetal attachment. Materials and Methods: This cross sectional study was conducted on 241 pregnant women in 2012. The necessary data was collecte...
Although the evolutionary functions of attachment in infant-caregiver relationships are undisputed, it is unclear what functions--if any--attachment serves in adult romantic relationships. The objective of this research was to examine the evolution and function of adult attachment (i.e., pair bonding) by applying comparative and phylogenetic methods to archival data collected on 2 diverse sampl...
Background and Aims: There are contradictory results in studies on the relationship between maternal-fetal attachment behaviors and anxiety in high-risk pregnancies. This study aimed to determine the relationship between maternal-fetal attachment and anxiety and demographic characteristics of first pregnant women with high-risk pregnancies. Methods: In this cross-sectional study, 200 pregnant...
Parent-of-origin-dependent (epi)genetic factors are important determinants of prenatal development that program adult phenotype. However, data on magnitude and specificity of maternal and paternal genome effects on fetal bone are lacking. We used an outbred bovine model to dissect and quantify effects of parental genomes, fetal sex, and nongenetic maternal effects on the fetal skeleton and anal...
In mammals, imprinted gene expression results from the sex-specific methylation of imprinted control regions (ICRs) in the parental germlines. Imprinting is linked to therian reproduction, that is, the placenta and imprinting emerged at roughly the same time and potentially co-evolved. We assessed the transcriptome-wide and ontology effect of maternally versus paternally methylated ICRs at the ...
Prenatal diagnosis (PD) is available for pregnancies at risk of monogenic disorders. However, PD requires the use of invasive obstetric techniques for fetal-sample collection and therefore, involves a risk of fetal loss. Circulating fetal DNA in the maternal bloodstream is being used to perform non-invasive prenatal diagnosis (NIPD). NIPD is a challenging discipline because of the biological fe...
Background: Although pregnancy and motherhood are enjoyable experiences, they are associated with many physical and psychological changes requiring adaptation. The present study aimed to assess the effectiveness of relaxing music on the life distress and maternal-fetal attachment of pregnant women. Methods: It was a quasi-experimental study with pre-test and post-test design and a control gr...
