Normal Function of the mushroom body defect Gene of Drosophila Is Required for the Regulation of the Number and Proliferation of Neuroblasts
1994
In the developing central nervous system of Drosophila, proliferation follows a reproducible and well-described spatial and temporal pattern. This pattern involves a defined number and distribution of neural stem cells (neuroblasts), as well as a precisely regulated time course of division of these neuroblasts. We show that mutations in the mushroom body defect (mud) gene interfere with the regulation of this pattern in a rather specific manner. In the abdominal neuromeres a subset of neuroblasts prolongs the period of proliferation. Additional daughter cells persist into the imago. Similar defects are expressed in the anterior ventral nerve cord and in the lateral central brain region. In …
Neuroblast formation and patterning during early brain development in Drosophila.
2004
The Drosophila embryo provides a useful model system to study the mechanisms that lead to pattern and cell diversity in the central nervous system (CNS). The Drosophila CNS, which encompasses the brain and the ventral nerve cord, develops from a bilaterally symmetrical neuroectoderm, which gives rise to neural stem cells, called neuroblasts. The structure of the embryonic ventral nerve cord is relatively simple, consisting of a sequence of repeated segmental units (neuromeres), and the mechanisms controlling the formation and specification of the neuroblasts that form these neuromeres are quite well understood. Owing to the much higher complexity and hidden segmental organization of the bra…
Adherence to the New Nordic Diet during pregnancy and subsequent maternal weight development: a study conducted in the Norwegian Mother and Child Coh…
2018
AbstractThe rising prevalence of overweight and obesity is a worldwide public health challenge. Pregnancy and beyond is a potentially important window for future weight gain in women. We investigated associations between maternal adherence to the New Nordic diet (NND) during pregnancy and maternal BMI trajectories from delivery to 8 years post delivery. Data are from the Norwegian Mother and Child Cohort. Pregnant women from all of Norway were recruited between 1999 and 2008, and 55 056 are included in the present analysis. A previously constructed diet score, NND, was used to assess adherence to the diet. The score favours intake of Nordic fruits, root vegetables, cabbages, potatoes, oatme…
Deliveries by caesarean sections on request of women: legal-medical evidence
2014
Introduction: In Italy the use of caesarean delivery has a rising trend moving away from European standards appeared on Euro-Peristat on maternal and child health, presenting the highest percentage of use of this procedure with significant regional differences. This study have analyzed the most recent data of a Sicilian reality about normal delivery and caesarean sections carried out in a hospital situated in Messina (Italy). Materials and methods: A total number of 1,573 medical records from 1st January 2011 to 31st December 2013 were analyzed and data gathered were statistically examined to describe general and specific parameters of the sample making use of Epi Info 7.1.4 software (CDC A…
Perinatal Parenting Stress, Anxiety, and Depression Outcomes in First-Time Mothers and Fathers: A 3- to 6-Months Postpartum Follow-Up Study
2016
Objective: Although there is an established link between parenting stress, postnatal depression, and anxiety, no study has yet investigated this link in first-time parental couples. The specific aims of this study were 1) to investigate whether there were any differences between first-time fathers’ and mothers’ postnatal parenting stress, anxiety, and depression symptoms and to see their evolution between three and 6 months after their child’s birth; and 2) to explore how each parent’s parenting stress and anxiety levels and the anxiety levels and depressive symptoms of their partners contributed to parental postnatal depression. Method: The sample included 362 parents (181 couples; mothers…
Biomonitoring of bisphenols A, F, S and parabens in urine of breastfeeding mothers: Exposure and risk assessment
2019
In the present study we used human biomonitoring to assess the internal exposure and the risk to four parabens and three bisphenols in 103 Spanish breastfeeding mothers participating in the BETTERMIILK project. Urinary methylparaben (MP), ethylparaben (EP), propylparaben (PP) and butylparaben (BP) presented detection frequencies ranging from 12% (BP) to 92% (MP), while bisphenol A (BPA), bisphenol F (BPF) and bisphenol S (BPS) were detected in 76% (BPA) and 20% (BPF, BPS) of the mothers. Average paraben concentrations (geometric mean) ranged from 0.021 ng mL(-1) (BP) to 17.7 ng mL(-1) (MP), whereas bisphenols had geometric means concentrations from 0.042 ng mL(-1) (BPF) to 0.927 ng mL(-1) (…
Position Statement on Breastfeeding from the Italian Pediatric Societies
2015
The 2015 Position Statement on Breastfeeding of The Italian Pediatric Societies (SIP, SIN, SICupp, SIGENP) recognizes breastfeeding as an healthy behaviour with many short and long term benefits for both mother and infant. While protecting, promoting and supporting breastfeeding, neonatologists and pediatricians need specific knowledge, skills and a positive attitude toward breastfeeding. In Maternity Hospitals and in Neonatal Units, appropriate organizative interventions should be applied in order to facilitate the beginning of breastfeeding and the use of mother’s/human milk. The Italian Pediatric Societies indicate the desiderable goal of around 6 months exclusive breastfeeding if the in…
P72 Lived experiences of midwives and traditional birth attendants caring for pregnant teenagers and teenage mothers: a phenomenological study
2020
Background Teenage mothers are confronted with the double task of passing through the teenage phase and, at the same time, familiarizing themselves with the requirements of motherhood. The characteristics connected with the teenage stage mostly affect the capability of teenage mothers to adapt to the role of being a first-time mother. The essential role of midwives is to provide care for women during pregnancy and motherhood, through coaching, reassurance, supervision and social support. Traditional Birth Attendants (TBAs) are also valued as essential actors in maternal health, providing social support and other antenatal, intrapartum and postnatal care in developing countries. The study ai…
Cell cycle independent role of Cyclin E during neural cell fate specification in Drosophila is mediated by its regulation of Prospero function
2009
AbstractDuring development, neural progenitor cells or neuroblasts generate a great intra- and inter-segmental diversity of neuronal and glial cell types in the nervous system. In thoracic segments of the embryonic central nervous system of Drosophila, the neuroblast NB6-4t undergoes an asymmetric first division to generate a neuronal and a glial sublineage, while abdominal NB6-4a divides once symmetrically to generate only 2 glial cells. We had earlier reported a critical function for the G1 cyclin, CyclinE (CycE) in regulating asymmetric cell division in NB6-4t. Here we show that (i) this function of CycE is independent of its role in cell cycle regulation and (ii) the two functions are m…
Application of latent class analysis in assessing the awareness, attitude, practice and satisfaction of paediatricians on sleep disorder management i…
2020
Aim To identify subgroups regarding paediatricians’ awareness, attitude, practice and satisfaction about management of Sleep-Disordered Breathing (SDB) in Italy using Latent Class Analysis (LCA). Methods A cross-sectional study was conducted on a large sample of Italian paediatricians. Using a self-administered questionnaire, the study collected information on 420 Paediatric Hospital Paediatricians (PHPs) and 594 Family Care Paediatricians (FCPs). LCA was used to discover underlying response patterns, thus allowing identification of respondent groups with similar awareness, attitude, practice and satisfaction. A logistic regression model was used to investigate which independent variables i…
