Ali Güncan, Ebru Gümüs
The filbert aphid Myzocallis coryli (Goeze) is a serious pest of hazelnut in North America, Italy, Spain, and Turkey. To evaluate the resistance of hazelnut to this insect, aphids were reared on five major cultivars ('Tombul,' 'Palaz,' 'Çakıldak,' 'Foşa,' and 'Mincane') under laboratory conditions. The developmental times of preadult and adult stages, total longevity, reproduction, and life table parameters were analyzed according to age-stage, two-sex life table theory, in which the stage differentiation and variable developmental rates among individuals could be described...

OBJECTIVE: We demonstrated previously that the Trauma and Attachment Group (TAG) program for youth in middle childhood significantly improved caregiver/child attachment relationships, reduced children's symptoms of attachment trauma, and increased the caregiver's ability for self-reflection. Here we examine the perspectives of both those administering and those taking part in this intensive dyad-based group intervention. METHODS: Utilizing an ethnographic design we collected and analyzed qualitative data obtained through a focus group and interviews with program facilitators, as well as interviews with participating caregivers...

Dravet syndrome (DS) is a well-recognized developmental and epileptic encephalopathy associated with SCN1A mutations and 15% mortality by 20 years. Although over half of cases succumb to sudden unexpected death in epilepsy, the cause of death in the remainder is poorly defined. We describe the clinical, radiologic, and pathologic characteristics of a cohort of children with DS and SCN1A mutations who developed fatal cerebral edema causing mass effect after fever-associated status epilepticus. Cases were identified from a review of children with DS enrolled in the Epilepsy Genetics Research Program at The University of Melbourne, Austin Health, who died after fever-associated status epilepticus...

BACKGROUND: Regular health visits for parents with young children provide an opportunity for developmental surveillance and anticipatory guidance regarding common childhood problems and help to achieve optimal developmental progress prior to school entry. However, there are few published reports from Australian culturally and linguistically diverse (CALD) communities exploring parents' experiences for accessing child health surveillance programs. This paper aims to describe and explain parental experiences for accessing developmental surveillance and anticipatory guidance for children...

Background: Developmental coordination disorder (DCD) is described as a motor skill disorder characterized by a marked impairment in the development of motor coordination abilities that significantly interferes with performance of daily activities and/or academic achievement. Since some electrophysiological studies suggest differences between children with/without motor development problems, we prepared an experimental protocol and performed electrophysiological experiments with the aim to make a step towards a possible diagnosis of this disorder using the event-related potentials (ERP) technique...

Planarians have a long history in the fields of developmental and regenerative biology. These animals have also sparked interest in neuroscience due to their neuroanatomy, spectrum of simple behaviors, and especially, their almost unparalleled ability to generate new neurons after any type of injury. Research in adult planarians has revealed that neuronal subtypes homologous to those found in vertebrates are generated from stem cells throughout their lives. This feat is recapitulated after head amputation, wherein animals are capable of regenerating whole brains and regaining complete neural function...

The interplay between transcription factors and chromatin dictates gene regulatory network activity. Germ layer specification is tightly coupled with zygotic gene activation and, in most metazoans, is dependent upon maternal factors. We explore the dynamic genome-wide interactions of Foxh1, a maternal transcription factor that mediates Nodal/TGF-β signaling, with cis-regulatory modules (CRMs) during mesendodermal specification. Foxh1 marks CRMs during cleavage stages and recruits the co-repressor Tle/Groucho in the early blastula...

BACKGROUND: Many transgender college students struggle with identity formation and other emotional, social, and developmental challenges associated with emerging adulthood. A potential maladaptive coping strategy employed by such students is heavy drinking. Prior literature has suggested greater consumption and negative alcohol-related consequences (ARCs) in transgender students compared with their cisgender peers, but little is known about their differing experiences with alcohol-related blackouts (ARBs)...

Bisphenol-A (BPA) is a component of polycarbonate and other plastics to which humans are regularly exposed at low levels. BPA is characterized as an endocrine disruptor due to observations of its estrogenic activity in various experimental models. We have previously shown evidence of disrupted hypothalamic feeding circuitry and leptin sensitivity in adult BPA-exposed animals subject to a high-fat diet, but because these animals were already exhibiting a diet-induced obese phenotype, we could not rule out the possibility that these observations were simply consequences of the obesity, not a pre-existing phenotype produced by BPA exposure...

The maternal-to-zygotic transition (MZT) marks the period when the embryonic genome is activated and acquires control of development. Maternally inherited factors play a key role in this critical developmental process, which occurs at the 2-cell stage in mice. We investigated the function of the maternally inherited factor STELLA (DPPA3) using single-cell/embryo approaches. We show that loss of maternal STELLA results in widespread transcriptional mis-regulation and a partial failure of MZT. Strikingly, activation of endogenous retroviruses (ERVs) is significantly impaired in Stella maternal/zygotic knockout embryos, which in turn leads to a failure to upregulate chimeric transcripts...

Developmental programming is influenced by perinatal nutrition and it has long-lasting impacts on adult metabolism in the offspring. In particular, maternal high fat diet has been associated with increased risk of obesity and metabolic disorders during adulthood in the descendants. These effects may be due to the effects of the high fat diet on the development of the systems that regulate food intake and energy balance in the offspring hypothalamus. The arcuate nucleus (ARC) may be a particularly sensitive region to it as this nucleus contains the POMC and AgRP/NPY neurons that integrate the melanocortin system...

OBJECTIVE: Prenatal stress influences fetal developmental trajectories, which may implicate glucocorticoid mechanisms. There is also emerging evidence that effects of prenatal stress on offspring development are sex-dependent. However, little is known about the prospective relationship between maternal prenatal cortisol levels and infant behaviour, and whether it may be different in male and female infants. We sought to address this question using data from a prospective longitudinal cohort, stratified by risk...

The elimination of infected or tumor cells by direct lysis is a key T and NK cell effector function. T and NK cells can kill target cells by coordinated secretion of cytotoxic granules containing one or both pore-forming proteins, perforin and granulysin and combinations of granzyme (Gzm) family effector proteases (in humans: Gzm A, B, K, M and H). Understanding the pattern of expression of cytotoxic molecules and the relationship to different states of T and NK cells may have direct relevance for immune responses in autoimmunity, infectious disease and cancer...

Maternal immune activation (MIA) via infection during pregnancy is known to increase risk for autism spectrum disorder (ASD). However, it is unclear how MIA disrupts fetal brain gene expression in ways that may explain this increased risk. Here we examine how MIA dysregulates rat fetal brain gene expression (at a time point analogous to the end of the first trimester of human gestation) in ways relevant to ASD-associated pathophysiology. MIA downregulates expression of ASD-associated genes, with the largest enrichments in genes known to harbor rare highly penetrant mutations...

Cancer metastasis occurs through local invasion of circulating tumour cells (CTCs), intravasation, transportation to distant sites, and their extravasation followed by colonisation at secondary sites. Epithelial-mesenchymal transition (EMT) is a normal developmental phenomenon, but its aberrant activation confers tumour cells with enhanced cell motility, metastatic properties, resistant to therapies and cancer stem cell (CSC) phenotype in epithelium-derived carcinoma. Experimental studies from various research papers have been reviewed to determine the factors, which interlink cancer stemness and cellular plasticity with EMT...

Adolescents' ethnic-racial identity (ERI) formation represents an important developmental process that is associated with adjustment. The Identity Project intervention, grounded in developmental theory, was designed to engage adolescents in the ERI processes of exploration and resolution. The current small-scale efficacy trial involved an ethnic-racially diverse sample of adolescents (N = 215; Mage  = 15.02, SD = .68) from eight classrooms that were randomly assigned by classroom to the intervention or attention control group...

Hypertension and chronic kidney disease (CKD) have a significant impact on global morbidity and mortality. The Low Birth Weight and Nephron Number Working Group has prepared a consensus document aimed to address the relatively neglected issue for the developmental programming of hypertension and CKD. It emerged from a workshop held on April 2, 2016, including eminent internationally recognized experts in the field of obstetrics, neonatology, and nephrology. Through multidisciplinary engagement, the goal of the workshop was to highlight the association between fetal and childhood development and an increased risk of adult diseases, focusing on hypertension and CKD, and to suggest possible practical solutions for the future...

Neural cultures derived from Huntington's disease (HD) patient-derived induced pluripotent stem cells were used for 'omics' analyses to identify mechanisms underlying neurodegeneration. RNA-seq analysis identified genes in glutamate and GABA signaling, axonal guidance and calcium influx whose expression was decreased in HD cultures. One-third of gene changes were in pathways regulating neuronal development and maturation. When mapped to stages of mouse striatal development, the profiles aligned with earlier embryonic stages of neuronal differentiation...

Extreme levels of certain temperament traits can be early markers of different developmental pathways of attention-deficit/hyperactivity disorder (ADHD). However, the long-term utility of using these traits as predictors of ADHD is not fully known. This study includes 64 male adolescents (M age = 13.5), who have been followed since birth as part of a longitudinal study. The primary aim was to test effortful control (EC), activity level, and anger, measured in early childhood - both with mother's reports and laboratory assessments -as predictors of ADHD symptoms in adolescence...
