Management of infants with neural tube defects (NTDs) in NICU
2017
Neural tube defects (NTDs) are a group of congenital malformations of the central nervous system, which derive from an altered embryological development during neurulation. The different types of NTDs are closely related to their onset in the embryonic period; precocity is an index of greater severity of clinical manifestation. The myelomeningocele is one of the most common pathological conditions which is included into the spectrum of NTDs. It is characterized by the lack of fusion of the vertebral arches, resulting in eversion of the meninges and medullary content; it is the condition which clearly needs more assistance in the neonatal intensive care unit. The management of patients with …
The motor development of preterm infants after the neonatal intensive care unit
2017
The extra uterine environment is a hostile environment, due to noises, lights and different biological activities compared to intra uterine environment for infants born preterm or underweight. Stress and painful experiences may also impact developmental outcomes. In addition, developmental delay risks increase with the decrease in gestational age. Thus, those born with immature developed systems may need neonatal intensive care units (NICU) in order to allow a correct growth and body maturation. In general, infants that need NICUs suffer from a slower development compared to their full-term peers. This may translate in a delay in oral, tactile, kinesthetic, vestibular, auditory, olfactory, …

Hearing loss in neonatal intensive care units (NICUS): Follow-up surveillance
2017
Infants admitted to the neonatal intensive care unit (NICU), who represent the 4-8% of all births, present problems such as prematurity, low Apgar scores, infections, hyperbilirubinemia and hearing impairment. In particular significant hearing loss is the most common disorder at birth, occurring in 1 to 2 newborns per 1000 in the general population and 24% to 46% of newborns who are admitted to a NICU. This leads more difficulty to develope verbal skills (learning vocabulary, grammar, word order and idiomatic expressions), language, learning and speech. Hearing impairment influences also cognitive and affective development of infants making consequences in their interpersonal relationships.…
Research of genetic and molecular determinants involved in the nodulated root system architecture of legumes and contributing to improved nitrogen nu…
2016
Grain legume pulse crops are of great interest to allow a production of seeds high nutritional value without any contribution of nitrate fertilizer. The nitrogen nutrition of legumes depends indeed mainly on the fixation in nodules of atmospheric dinitrogen through the plant-rhizobium symbiosis, and to a lesser extent, absorption by roots of soil mineral nitrogen.A better understanding has been obtained on the genetic control of the development of roots and nodules and on their impact on nitrogen nutrition. High genetic variability of these characters has been detected, and the existence of genetic correlations between them demonstrated. A quantitative genetic approach has identified severa…
A new method for the labelling of proteins with radioactive arsenic isotopes
2006
Abstract Radioarsenic labelled radiopharmaceuticals could be a valuable asset to positron emission tomography. In particular, the long half-lives of 72As ( T 1 / 2 = 26 h ) and 74As ( T 1 / 2 = 17.8 d ) allow to investigate slow physiological or metabolical processes, like the enrichment and distribution of monoclonal antibodies (mab) in tumour tissue. In this work, a new method for the labelling of proteins with various radioactive arsenic isotopes was developed. For this purpose, two proteins, namely a chimeric IgG3 monoclonal antibody, ch3G4, directed against anionic phospholipids, and Rituxan (Rituximab), were labelled as a proof of principle with no-carrier-added radioarsenic isotopes…
Modelling leaky photonic wires: a mode solver comparison
2006
We present results from a mode solver comparison held within the framework of the European COST P11 project. The structure modelled is a high-index contrast photonic wire in silicon-oninsulator subject to substrate leakage. The methods compared are both in-house developed and commercial, and range from effective index and perturbation methods, over finite-element and finite-difference codes, beam propagation methods, to film mode matching methods and plane wave expansion methods.
Linear representations of Artin groups
2016
Let Г be a Coxeter graph. Let W be the Coxeter group, A be the Artin group, and A+ be the Artin monoid associated with Г. Let G be a group of symmetries of Г. Then G acts on W, A and A+. The fixed subgroup WG is known to be a Coxeter group, the fixed submonoid A+G is known to be an Artin monoid, and, when Г is of spherical type, the fixed subgroup AG is known to be an Artin group. This thesis studies the behavior of WG, A+G and AG with respect to some faithful linear representations of W, A and A+, respectively.Firstly, we consider the rooted representations of the Coxeter groups introduced by Krammer in his Ph. D. Thesis. These are a generalization of the canonical representations. We take…
Effects of hospital facilities on patient outcomes after cancer surgery
2022
© 2022 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY 4.0 licenseBackground: Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide. Methods: A multimethods analysis was performed as part of the GlobalSurg 3 study—a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal,…
Plasma membrane redox system in the erythrocytes of rowers: Pilot study
2017
The oxidative stress results from a change in the physiological balance between oxidant and antioxidant species. This type of stress is a chemical change in the redox state of cells. The increased production of reactive species is related to an excessive metabolic activation, for example, from an intense physical exercise or an excessive caloric intake (1). In physiological conditions, muscle fibers are provided with an antioxidant system able to keep under control the excessive production of Reactive Oxygen Species (ROS).
