Background: Interactions between inbreeding and maternal effects have received little attention, and the effect of maternal age on inbreeding depression in offspring has been almost entirely neglected. Maternal age affects allocation of resources and other materials to offspring, which can affect the fitness consequences of inbreeding. An interaction between inbreeding and maternal age thus has...

Attachment anxiety (fear of abandonment) is associated with disinhibited eating in adults. Both maternal disinhibited eating and use of emotional feedings strategies are associated with emotional eating in children. On this basis, the current study sought to determine whether attachment anxiety is an underlying maternal characteristic that predicts parental reports of child emotional over-eatin...

OBJECTIVE The aim of this study was to determine (i) the effect of maternal obesity and gestational diabetes mellitus (GDM) on (i) the circulating levels of omentin-1 in cord and maternal plasma, and (ii) gene expression and release of omentin-1 from human placenta and adipose tissue. The effect of pregnancy on circulating omentin-1 levels was also determined. DESIGN Omentin-1 levels were mea...

Maternal effects have wide-ranging effects on life-history traits. Here, using the crustacean Daphnia magna, we document a new effect: maternal food quantity affects offspring feeding rate, with low quantities of food triggering mothers to produce slow-feeding offspring. Such a change in the rate of resource acquisition has broad implications for population growth or dynamics and for interactio...

This study examines whether maternal employment affects the health status of low-income, elementary-school-aged children using instrumental variables estimation and experimental data from a welfare-to-work program implemented in the early 1990s. Maternal report of child health status is predicted as a function of exogenous variation in maternal employment associated with random assignment to th...

Timed-pregnant Sprague-Dawley (CD) outbred rats and New Zealand White rabbits were dosed by gavage with methacrylonitrile (MACR) in distilled water during major organogenesis. Rats were dosed on Gestational Days (GD) 6 through 15 (0, 5, 25, or 50 mg MACR/kg/day) and rabbits on GD 6 through 19 (0, 1, 3, or 5 mg MACR/kg/day). Maternal clinical status was monitored daily during treatment. At termi...

AIMS Epidemiological and animal studies have shown that maternal diet can influence metabolism in adult offspring. However, the molecular mechanisms underlying these changes remain poorly understood. Here, we characterize the phenotypes induced by maternal obesity in a mouse model and examine gene expression and epigenetic changes induced by maternal diet in adult offspring. METHODS We analyz...

The Swedish health registries were used to investigate a possible effect on the incidence of neural tube defects (NTDs) of maternal smoking and maternal body mass index (BMI) (kg/m2). Among 1,199,701 infants born in 1983-1993 with known smoking exposure in early pregnancy, 621 infants with NTDs were selected. After controlling for year of birth, maternal age, parity, education level, BMI, and i...

economic data and performance records from 10 iranian holstein dairy cattle herds, as well as milk production and fertility records from iranian center of animal breeding and animal production improvment were used to estimate the effect of calving difficulty on milk production, fertility and as well on the economic aspects of maternal and direct calving difficulty. calving difficulty could be d...

Maternal alcohol consumption during pregnancy can produce teratogenic effects and has a detrimental effect on the development of the fetus. In this study, the dose-dependent effect of maternal alcohol administration on the expression of nitric oxide synthase (NOS) in the hippocampus of the offspring rats was investigated. From the present result, it was shown that expression of NOS is decreased...
