BACKGROUND: Fetal alcohol syndrome (FAS) is caused by maternal alcohol consumption during pregnancy, although additional factors must be involved, as development and severity are not directly related to alcohol intake. The abnormal glycosylation caused by alcohol might play a role in FAS according to the clinical similarities shared with congenital disorders of glycosylation (CDG). Thus, mutations underlying CDG, affecting genes involved in glycosylation, could also be involved in FAS...

Cushing syndrome (CS) during pregnancy is a rare condition with only a few cases reported in the literature. Misdiagnosis of CS is common because of overlapping features like fatigue, weight gain, striae and emotional changes that can occur during normal pregnancy. Changes in maternal hormones and their binding proteins complicate assessment of glucocorticoid hormone levels during gestation. CS during pregnancy is most frequently due to an adrenal adenoma and to a lesser degree to adrenocorticotropic hormone (ACTH) hypersecretion by a pituitary adenoma...

Sow immunity plays an important role in preventing viral infection and disease in newborn piglets. Vertical transmission of porcine circovirus type 2 (PCV2) may perpetuate porcine circovirus associated disease (PCVAD) in newborn and growing pigs. Hence, the immunological effects of maternal immunoglobulin transfer of PCV2-specific antibodies on PCV2 viremia and immune response in piglets in commercial swine herds were evaluated. Sow vaccination has been shown to reduce viral shedding and viremia, and increases the neutralizing antibody (NA) titers...

BACKGROUND: Low-income Hispanic women experience elevated rates of high postpartum weight retention (PPWR), which is an independent risk factor for lifetime obesity. Sociocultural factors might play an important role among Hispanic women; however, very few studies have examined this association. OBJECTIVE: The purpose of our study was to examine the associations between acculturation and maternal diet, physical activity, and PPWR. DESIGN: This is a cross-sectional study of baseline data from 282 Hispanic women participating in the FitMoms/Mamás Activas study, a randomized controlled trial examining the impact of primarily an internet-based weight control program, in reducing PPWR among low-income women...

Chemokines play an important role in regulating the complex immune system at the maternal-fetal interface during pregnancy. Among various chemokines, C-C motif chemokine ligand 2 (CCL2) plays a role in the recruitment of immune regulatory cells to implantation sites within the endometrium. In cattle, CCL2 is abundantly expressed in the uterine endometrium. However, its intracellular signaling has not been identified. In this study, we examined the effects of CCL2 on bovine endometrial (BEND) cell proliferation...

The formation of a zygote via the fusion of an egg and sperm cell and its subsequent asymmetric division (ACD) herald the start of the plant's life cycle. Zygotic genome activation (ZGA) is thought to occur gradually, with the initial steps of zygote and embryo development being primarily maternally controlled, and subsequent steps being governed by the zygotic genome. Here, using maize (Zea mays) as a model plant system, we determined the timing of zygote development and generated RNA-Seq transcriptome profiles of gametes, zygotes, and apical and basal daughter cells...

The oxytocin/vasopressin ancestor molecule has been regulating reproductive and social behaviors for more than 500 million years. In all mammals, oxytocin is the hormone indispensable for milk-ejection during nursing (maternal milk provision to offspring), a process that is crucial for successful mammalian parental care. In laboratory mice, a remarkable transcriptional activation occurs during parental behavior within the anterior commissural nucleus (AC), the largest magnocellular oxytocin cell population within the medial preoptic area (although the transcriptional activation was limited to non-oxytocinergic neurons in the AC)...

Childhood vaccination has played a critical role in the reduction of morbidity and mortality from communicable diseases, including specific respiratory pathogens. Acute lower respiratory infection (ALRI) of both bacterial and viral aetiology continues to impact global child health. Key bacterial pathogens including Streptococcus pneumoniae and Haemophilus influenza type b are specifically targeted with current vaccination programmes, while at present there are less effective strategies for the prevention of viral disease...

Placental function is complex and influenced by various factors; furthermore, it depends on a delicate balance between cell proliferation, cell differentiation, and cell death. Bcl-2 and Bax proteins are key apoptosis regulators and are considered to play an important role in the maintenance of both dynamic balance and integrity of many tissues. Changes in Bcl-2 and Bax expressions have been described during different developmental stages in normal human placentas. Studies furthermore indicated several pathological placental changes to be related to abnormal Bcl-2 and Bax expressions...

Parental induction of empathy-related guilt plays an important role in children's moral development. However, guilt induction can also be psychologically controlling and detrimental for youth adjustment. This study provided a more nuanced view of parental guilt induction by examining how the nature of a child's misdeed and the structure and content of the parental guilt inductive statement impact children's perceptions of it. Using hypothetical vignettes, this study experimentally examined the impact of the type (domain) of child behavior, highlighted victim, and focus of parental criticism on 156 children's and early and middle adolescents' (age: Ms = 8...

Long non-coding RNAs (lncRNAs) act critical roles in many biological processes, including cell proliferation, apoptosis, development, invasion and migration. LncRNA maternally expressed gene 3 (MEG3) is found to be downregulated in several tumors; however, its role in the atherosclerosis is still unknown. In the present study, we demonstrated that MEG3 expression level was downregulated in the coronary artery disease (CAD) tissues compared to in the control tissues. We also showed that TNF-α enhanced EC cell proliferation...

BACKGROUND: Over the past several decades, the age of pubertal onset in girls has shifted downward worldwide. As early pubertal onset is associated with increased risky behavior and psychological issues during adolescence and cardiometabolic disease and cancer in adulthood, this is an important public health concern. Exposure to endocrine disrupting chemicals during critical windows of in utero development may play a role in this trend. Our objective was to investigate trimester-specific phthalate and BPA exposure in relation to pubertal development among girls in the Early Life Exposure in Mexico to Environmental Toxicants (ELEMENT) birth cohort...

Heterosis has been widely utilized in agriculture and is important for world food safety. Many genetic models have been proposed as mechanisms underlying heterosis during the past century, yet more evidence is needed to support such models. To investigate heterosis in two-line hybrid rice, we generated a partial diallel crossing scheme, which consisted of approximately 500 F1 hybrids derived from 14 male sterile lines and 39 restorer lines. In this population, increased panicle number played the most important role in yield heterosis of hybrid rice...

Alcohol consumption during pregnancy remains a significant cause of preventable birth defects and developmental disabilities, however, the mechanism of toxicity remains unclear. Methanol is present as a congener in many alcoholic beverages and is formed endogenously. Since ethanol is preferentially metabolized over methanol, it has been found in the sera and CSF of alcoholics. Toxicity resulting from methanol has been attributed to formic acid. Formic acid is present in significantly higher quantities in biofluids of alcoholic patients...

The appearance of new mutations in polymorphic markers plays a central role in a range of genetic applications, including dating phylogenetic events, informing disease studies, and evaluating forensic evidence. The present study estimated the mutation rates of 21 autosomal short tandem repeat (STR) loci in a population from Central Brazil. We studied 15,046 paternity cases from Goiás, Brazil from August 2012 to February 2015. We identified 262 mutations in the 21 loci. The loci that presented more mutations were FGA and D18S51, with a total of 46 and 28 mutations, respectively...

Cortisol, the main glucocorticoid stress hormone in teleost fish, is of interest as a mediator of maternal stress on offspring characteristics because it plays an organizational role during early development. The present study tested the hypothesis that maternal exposure to cortisol treatment prior to spawn affects offspring phenotype using wild largemouth bass (Micropterus salmoides). Baseline and stress-induced cortisol concentrations, body size (i.e. length and mass), and behavior (i.e. anxiety, exploration, boldness, and aggression) were assessed at different offspring life-stages and compared between offspring of control and cortisol-treated females...

POU3F2/BRN-2 is a transcription factor that is mainly expressed in the central nervous system and plays an important role in brain development. The transactivation domain of POU3F2 includes multiple mammalian-characteristic tandem amino acid repeats (homopolymeric amino acid repeats). We previously generated knock-in mice (Pou3f2(Δ)(/Δ) mice) in which all three homopolymeric amino acid repeats were deleted from the Pou3f2 transactivation domain and identified phenotypic impairments in maternal behavior and pup recognition...

Preeclampsia (PE) remains a main cause of maternal morbidity and mortality during pregnancy. Vascular spasm and ischemic damage play the primary role in the presentation of PE. The aim of this study was to assess the longitudinal strain (LS) in each of the three myocardial layers in patients with PE using the layer-specific strain. Forty-five PE women and forty-one normotensive pregnant women were included. Layer-specific LS were assessed in endocardium, mid-myocardium, and epicardium by 2-dimensional (2D) speckle-tracking echocardiography (STE)...

AIMS: Maternal dietary restriction during pregnancy impairs nephron development and results in offspring with fewer nephrons. Cell turnover in the early developing kidney is altered by exposure to maternal dietary restriction and may be regulated by the LIM-kinase family of enzymes. We set out to establish whether disturbance of LIM-kinase activity might play a role in the impairment of nephron formation. MAIN METHODS: E12.5 metanephric kidneys and HK2 cells were grown in culture with the pharmacological LIM-kinase inhibitor BMS5...
