Parents' exposure to stressful ecosocial situations, like inadequate resources, is linked to parents' perceptions of infants' fussing and crying and less sensitive caregiving. However, studies supporting these findings predominantly come from Western contexts of parenting and infant care. Ecosocial situations may have different effects on parenting and infants in distinct cultural contexts. Read More

Objectives: Suboptimal breastfeeding contributes to morbidity and mortality in children. Studies in high-income countries (HICs) show that exclusive-breastfeeding (EBF) is associated with longer breastfeeding duration. The aim of this study was to determine whether maternal reports of EBF at six months are associated with longer duration of breastfeeding during the first two years of life in a low and middle-income country (LMIC) setting, and to identify determinants of breastfeeding duration.

This study tested the hypotheses that maternal and paternal effects differentially influence expression of their offspring's adult behavior and underlying neural mechanisms. We predicted that maternal influences would be greater than paternal influences on male offspring. We tested these hypotheses by cross-breeding two phenotypically-, behaviorally- and neuroanatomically-distinct populations of prairie voles (Microtus ochrogaster) from Illinois, which are highly prosocial, and Kansas, which are significantly less prosocial.

Eggs have developed their own strategies for early development. Amphibian, teleost fish, and ascidian eggs show cortical rotation and an accompanying structure, a cortical parallel microtubule (MT) array, during the one-cell embryonic stage. Cortical rotation is thought to relocate maternal deposits to a certain compartment of the egg and to polarize the embryo. Read More

Background: Age-related decline in reproductive potential is mainly due to the increased incidence of aneuploidy. Furthermore, two recent studies have shown that euploid embryos of older women may have a lower implantation potential compared to those of younger women, suggesting that aging might compromise embryos beyond their ploidy status. However, the inherent limitations of these studies preclude solid conclusions. Read More

The compilation of archaeological and genetic data for ancient European human groups has provided persuasive evidence for a complex series of migrations, population replacements and admixture until the Bronze Age. If the Bronze-to-Iron Age transition has been well documented archaeologically, ancient DNA (aDNA) remains rare for the latter period and does not precisely reflect the genetic diversity of European Celtic groups. In order to document the evolution of European communities, we analysed 45 individuals from the Late Iron Age (La Tène) Urville-Nacqueville necropolis in northwestern France, a region recognized as a major cultural contact zone between groups from both sides of the Channel.

The focus of my life in science, has been to improve reproductive health for women, with an emphasis on the endometrium, the most dynamic tissue in the human body: its remarkable cyclical remodelling is essential for establishment of pregnancy. The most notable events in a woman's endometrial cycle are menstruation and endometrial repair, regeneration of the endometrium during the proliferative phase, attainment of receptivity by the mid-secretory phase of the cycle and the embryo-maternal interactions that initiate peri-implantation events within the microenvironment of the uterine cavity. I have contributed to understanding the molecular and cellular changes underpinning these events, and how disturbance of them leads to menstrual disorders, infertility and endometrial diseases including abnormal uterine bleeding, endometriosis and endometrial cancer.

The placenta plays a pivotal role in the development of the fetal brain and also influences maternal brain function, but our understanding of communication between the placenta and brain remains limited. Using a gene expression and network analysis approach, we provide evidence that the placenta transcriptome is tightly interconnected with the maternal brain and fetal brain in d 15 pregnant C57BL/6J mice. Activation of serotonergic synapse signaling and inhibition of neurotrophin signaling were identified as potential mediators of crosstalk between the placenta and maternal brain and fetal brain, respectively.

Choline availability modulates neurogenesis and cerebral cortex development through the regulation of neural progenitor cell (NPC) proliferative and differentiation capacity. In this study, we demonstrated that cortical NPC self-renewal is controlled by choline via the expression of a microRNA (miR-129-5p), whose role in the developing brain has not been examined, and which, in turn, inhibits synthesis of the epidermal growth factor receptor (EGFR) protein. Specifically, we found that low choline (LC) availability led to the upregulation of miR-129-5p expression in cortical NPCs in vitro and in vivo, causing the downregulation of EGFR and thereby disrupting NPC self-renewal and cortical neurogenesis.

Prenatal ethanol (EtOH) exposure is known to induce adverse effects on fetal brain development. Docosahexaenoic acid (DHA) has been shown to alleviate these effects by upregulating antioxidant mechanisms in the brain. The liver is the first organ to receive enriched blood after placental transport; therefore, it could be negatively affected by EtOH, but no studies have assessed the effects of DHA on fetal liver.

This commentary applauds the authors of the monograph, The Mother-Child Attachment Partnership in Early Childhood: Secure Base Behavioral and Representational Processes, for their thorough and elegant exploration of the development of attachment working models in the preschool years in relation to maternal sensitivity and attachment representations, mother-child co-constructions of attachment-relevant stories, and children's own secure base behavior. These findings are set against a backdrop of children's memory development, with the recommendation that future research delves even younger to explore the development of attachment working models in children under 3 years. A second recommendation is to continue the work with older children, with a particular focus on the conversations they are having with caregivers about actual attachment-related experiences.

This study focused on the role of maternal co-construction skills in building attachment relevant representations in early childhood. Thirty-four mothers and their 4- to 5-year-old children were presented with two co-construction tasks, one an attachment storytelling task, the other an affect discussion task about emotion-laden situations. Maternal co-construction skills were assessed with several scales that scored the quality of the co-construction partnership, the mother's skill in prompting elaboration, and helping build an explanatory framework.

While numerous studies have demonstrated that mitochondrial genetic variation can shape organismal phenotype, the level of contribution the mitochondrial genotype makes to life-history phenotype across the life course remains unknown. Furthermore, a clear technical bias has emerged in studies of mitochondrial effects on reproduction, with many studies conducted on males, but few on females. Here, we apply a classic prediction of the evolutionary theory of aging to the mitochondrial genome, predicting the declining force of natural selection with age will have facilitated the accumulation of mtDNA mutations that confer late-life effects on female reproductive performance.
