This article reports on a longitudinal study investigating gender differences in the association between maternal disclosure and adolescents' depressive symptoms. Little research has examined the relationship of parental disclosure to adolescents' depressive symptoms and research on sex differences is particularly lacking. In a sample of 428 families with a mean age of 13.36 (52% female) of the...
The aim of this study was to estimate genetic components and parameters of retained placenta and dystocia traits in FOKA dairy farm. The non-genetic factors affecting these traits were evaluated using logistic regression implemented in GENMOD procedure of SAS 9.1 software. In order to do genetic evaluations, 5 Bayesian threshold models of repeat records and a Bayesian bivariate model were used....
Epidemiological studies suggest that allergy risk is preferentially transmitted through mothers. This can be due to genomic imprinting, where the phenotype effect of an allele depends on its parental origin, or due to maternal effects reflecting the maternal genome's influence on the child during prenatal development. Loss-of-function mutations in the filaggrin gene (FLG) cause skin barrier def...
introduction: there is a great deal of controversy regarding the effect of gestational magnesium (mg) deficiency on fetal growth and the incidence of low birth weight (lbw) in infants. therefore, this study aimed to delineate the possible relationship between maternal mg level and infant lbw. methods: this case-control study was conducted on 180 mothers in shiraz, iran. fasting blood samples we...
The long-term impact of early stress on behavior and emotions is well documented in humans, and can be modeled in experimental animals. In mice, maternal separation during early postnatal development induces poor and disorganized maternal care, and results in behavioral deficits that persist through adulthood. Here, we examined the long-term effect of unpredictable maternal separation combined ...
BACKGROUND Family planning is one of the four pillars of the Safe Motherhood Initiative to reduce maternal death in developing countries. We aimed to estimate the effect of contraceptive use on maternal mortality and the expected reduction in maternal mortality if the unmet need for contraception were met, at country, regional, and world levels. METHOD We extracted relevant data from the Mate...
Recent studies on hormone-mediated maternal effects in birds have highlighted the influence of variable maternal yolk androgen concentration on offspring phenotype, particularly in terms of early development. If genetic differences between laying females regulate variation in yolk hormone concentration, then this physiological maternal effect is an indirect genetic effect which can provide a ba...
