Vulnerability to emotional disorders like depression derives from interactions between early and late environments, including stressful conditions. The serotonin (5HT) system is strongly affected by stress and chronic unpredictable stress can alter the 5HT system. We evaluated the distribution of active serotonergic neurons in the dorsal raphe nucleus (DR) through immunohistochemistry in maternally separated and chronically stressed rats treated with an antidepressant, tianeptine, whose mechanism of action is still under review...

INTRODUCTION: Smoking during pregnancy is a significant public health concern that can cause adverse health outcomes for both the mother and fetus. Studies have shown only 40% of women quit smoking during pregnancy, with more than half relapsing within 6months, and up to 90% relapsing within one year. This study investigates differences in demographics and smoking-related symptomatology between pregnant smokers and pregnant quitters, as well as factors associated with postpartum relapse...

BACKGROUND: Global prevalence of overweight/obesity and gestational diabetes (GDM) is increasing. In pregnant women both conditions affect offspring's later health. Overweight/obesity is a risk factor of GDM; to what extent maternal overweight/obesity explains long-term effects of GDM in offspring is unknown. OBJECTIVE: To evaluate effects of maternal pre-pregnancy overweight/obesity (BMI ⩾25 kg/m(2)) and GDM, occurring together or separately, on body composition among adult offspring...

Despite robust investigations examining the impact of maternal anxiety and parenting behaviors and child anxiety risk, less is understood about the impact of paternal anxiety and parenting behaviors on child anxiety risk, particularly within the broader family context. An Actor Partner Interdependence Model (APIM) was used to examine whether paternal anxiety longitudinally predicted child anxiety risk indirectly through maternal and paternal parenting behaviors, while controlling for maternal anxiety. Both fathers and mothers of 12- to 30-month-olds (n = 94) provided self-report of their anxiety and parenting behaviors...

STUDY QUESTION: Does the use of a vascular contrast agent facilitate earlier detection of maternal flow to the placental intervillous space (IVS) in the first trimester of pregnancy? SUMMARY ANSWER: Microvascular filling of the IVS was demonstrated by contrast-enhanced ultrasound from 6 weeks of gestation onwards, earlier than previously believed. WHAT IS KNOWN ALREADY: During placental establishment and remodeling of maternal spiral arteries, endovascular trophoblast cells invade and accumulate in the lumen of these vessels to form 'trophoblast plugs'...

BACKGROUND: Controversy exists regarding ankyloglossia (tongue-tie) and its clinical impact on breastfeeding, including the benefits, or otherwise, of tongue-tie release (frenotomy). As exclusive breastfeeding rates in Ireland are already considerably low (46% on discharge home from the maternity unit following birth in 2014), it is imperative to protect and support breastfeeding, including identifying the associated effects that frenotomy might have on breastfeeding variables. OBJECTIVE: To determine the associated effects of frenotomy on breastfeeding variables in infants with ankyloglossia...

The effects of Communicative functions and Mind-Mindedness on children's language development have been typically investigated in separate studies. The present longitudinal research was therefore designed to yield new insight into the simultaneous impact of these two dimensions of maternal responsiveness on the acquisition of expressive language skills in a sample of 25 mother-child dyads. The frequencies of five communicative functions (Tutorial, Didactic, Conversational, Control and Asynchronous) and two types of mind-related comments (attuned vs...

Maize is one of the most widely cultivated crops. It accumulates a large quantity of seed storage proteins, which are important for seed development and germination, and contribute to the nutritional quality of seeds. Based on solubility, the storage proteins are divided into albumins (water-soluble), globulins (salt-soluble), prolamins (alcohol-soluble), and glutelins (acid- or alkali-soluble). Maize hybrids are cultivated due to the superior performance of F1 hybrids than that of their parents, a phenomenon known as heterosis...

Background: Preterm birth complications are the leading cause of deaths among children <5 years of age. Studies have suggested that group B Streptococcus (GBS) maternal rectovaginal colonization during pregnancy may be a risk factor for preterm delivery. This article is the fifth of 11 in a series. We aimed to assess the association between GBS maternal colonization and preterm birth in order to inform estimates of the burden of GBS. Methods: We conducted systematic literature reviews (PubMed/Medline, Embase, Latin American and Caribbean Health Sciences Literature [LILACS], World Health Organization Library Information System [WHOLIS], and Scopus) and sought unpublished data from investigator groups on the association of preterm birth (<37 weeks' gestation) and maternal GBS colonization (GBS isolation from vaginal, cervical, and/or rectal swabs; with separate subanalysis on GBS bacteriuria)...

OBJECTIVES: Multiple mechanisms have been proposed for the neuroprotective effects of magnesium sulfate (MgSO4). We aimed to examine the effects of lipopolysaccharide (LPS) and MgSO4 on the placental expression of nuclear factor κ light chain enhancer of activated B cells (NF-κB), interleukin (IL) 6, adrenocorticotropic hormone (ACTH), and nitric oxide synthase (NOS); all known to participate in the inflammatory cascade. METHODS: Placentas were obtained and selected cotyledons cannulated and dually perfused ex vivo...

Background: Maternal short stature has been observed to increase the risk of preterm birth; however, the aetiology behind this phenomenon is unknown. We investigated whether preeclampsia, an obstetric complication that often leads to preterm delivery and is reported to have an inverse association with women's height, mediates this association. Methods: We studied 218 412 women with no underlying diseases before pregnancy, who delivered singletons from 2005 to 2011 and were included in the Japan Society of Obstetrics and Gynecology perinatal database, which is a national multi-centre-based delivery database among tertiary hospitals...

Parental care is an important factor influencing offspring survival and adult reproductive success in many vertebrates. Parent-offspring recognition ensures care is only directed to filial young, avoiding the costs of misallocated resource transfer. It is essential in colonial mammal species, such as otariids (fur seals and sea lions), in which repeated mother-offspring separations increase the risk of misdirecting maternal effort. Identification of otariid pups by mothers is known to be multi-modal, yet the role of visual cues in this process remains uncertain...

Placental health is a key component to a successful pregnancy. Placental insufficiency (PI), inadequate nutrient delivery to the fetus, is associated with preeclampsia (PE), a maternal hypertensive disorder, and intrauterine growth restriction (IUGR), pathologically poor fetal growth. PI is more common in early-onset PE (EOPE) than late-onset PE (LOPE). However, the relationship between these disorders remains unclear. While DNA methylation (DNAm) alterations have been identified in PE and IUGR, these entities can overlap and few studies have analyzed them separately...
