Changes in Body Composition in Anorexia Nervosa : Predictors of Recovery and Treatment Outcome
2015
The restoration of body composition (BC) parameters is considered to be one of the most important goals in the treatment of patients with anorexia nervosa (AN). However, little is known about differences between AN diagnostic subtypes [restricting (AN-R) and binge/purging (AN-BP)] and weekly changes in BC during refeeding treatment. Therefore, the main objectives of our study were twofold: 1) to assess the changes in BC throughout nutritional treatment in an AN sample and 2) to analyze predictors of BC changes during treatment, as well as predictors of treatment outcome. The whole sample comprised 261 participants [118 adult females with AN (70 AN-R vs. 48 AN-BP), and 143 healthy controls].…
La antropología como ciencia libidinosa. Diderot y el viaje de Bougainville
2005
Son innumerables los estudios que han abordado, desde temprano, la historia de la constitución de la antropología como disciplina empírica con vocación 'científica', como una de las ciencias humanas. Se muestra así una cierta obsesión por los orígenes, quizá síntoma de una frágil identidad. Uno de esos textos, de los más tempranos, The History of Anthropology} 1 fue escrito por Boas justo al principio del siglo pasado (1904) y tiene por objeto -fue una conferencia dada ante un publico académico variopintoreflexionar históricamente sobre una disciplina que todavía se debate para delimitar cuál es su objeto y método epistemológicos. Boas advierte desde el principio que no va a proceder dicien…
Relationship between maternal body mass index, gestational weight gain and birth weight: prospective study in a health department
2015
Objetivo: Contrastar la relación que existe entre la ganancia de peso gestacional y el peso del recién nacido, entre cada categoría de IMC pregestacional. Material y Métodos: Estudio observacional y descriptivo con muestreo bietápico en el Departamento de Salud de la Ribera (Valencia, España). Se clasificaron en cuatro grupos dependiendo del índice de masa corporal (IMC) pregestacional. Resultados: Se estudiaron 140 gestantes. La evolución de la ganancia de peso gestacional (GPG) y de sus gradientes trimestrales fue ascendente. Se produjo un mayor incremento del primer al segundo trimestre que del segundo al tercero para todas las categorías de IMC pregestacional. Según las recomendaciones …
Ecología de los crustáceos dominantes en los lagos de la Antártida marítima
2016
La presente tesis aborda el estudio ecológico de los dos crustáceos más abundantes en los lagos de La Península Byers (Islas Shetland del Sur, Antártida), el anostráceo Branchinecta gaini y el copépodo Boeckella poppei. Esta región es considerada una de las zonas con mayor interés desde el punto de vista limnológico dentro del continente antártico. Los estudios realizados en los sistemas acuáticos de esta región son relativamente recientes aunque amplios, no obstante existe todavía un sesgo de carencia en lo que respecta al conocimiento de la ecología de estos crustáceos. Las condiciones climáticas de la Antártida marítima, menos severas que las de la región continental, conllevan la existe…
Study of oligogalacturonides-triggered Nitric Oxide (NO) production provokes new questioning about the origin of NO biosynthesis in plants
2014
Addendum to: Rasul S, Dubreuil-Maurizi C, Lamotte O, Koen E, Poinssot B, Alcaraz G, et al. Nitric oxide production mediates oligogalacturonide-triggered immunity and resistance to Botrytis cinerea in Arabidopsis thaliana. Plant Cell Environ 2012; PMID:22394204; http://dx.doi. org/10.1111/j.1365-3040.2012.02505.x.; International audience; We investigated the production and function of nitric oxide (NO) in Arabidopsis thaliana leaf discs as well as whole plants elicited by oligogalacturonides (OGs). Using genetic, biochemical and pharmacological approaches, we provided evidence that OGs induced a Nitrate Reductase (NR)-dependent NO production together with an increased NR activity and NR tran…
Distal Arthrogryposis type 5 in an Italian family due to an autosomal dominant gain-of-function mutation of the PIEZO2 gene
2022
Abstract Background Arthrogryposis multiplex congenita (AMC) is a group of clinically and etiologically heterogeneous conditions, characterized by prenatal onset contractures affecting two or more joints. Its incidence is about 1 in 3000 live births. AMC may be distinguished into amyoplasia, distal and syndromic arthrogryposis. Distal arthrogryposis (DA) predominantly affects hands and feet. It is currently divided into more than ten subtypes (DA1, DA2A/B, DA3–10), based on clinical manifestations, gene mutations and inheritance pattern. Among them, only a few patients with DA5 have been reported. It is associated to a gain-of-function pathogenic variant of the PIEZO2 gene, encoding for an …
Study of the use of methanol-filled Er-doped suspended-core fibres in a temperature-sensing ring laser system
2013
We report on an experimental/numerical investigation into the use of methanol-filled Er-doped suspended-core fibres (SCFs) in temperature-sensing ring laser systems. We have adopted a ring laser configuration that includes an Er-doped SCF as a temperature-dependent attenuator (TDA) with a step-index Er-doped fibre (EDF) as the laser active medium. The laser performance dependence on the temperature was measured both in continuous wave (CW) and transient regimes. CW laser output power and build-up time values are compared with those of similar laser systems based on other types of Er-doped PCFs or using other laser configurations. A notable variation of 0.73% °C−1 was achieved in CW operatio…
A novel noise figure and gain test set for microwave devices
2002
A new instrument for the measurement of noise and gain of microwave devices is presented. It differs from the commercial ones in the accomplishment of the gain measurement and is also useful for measuring mismatched devices such as transistors, The instrument is driven via HP-IB by a PC and a user-friendly virtual panel is designed to perform all the required operations. Also included is the possibility of removing the second-stage noise contribution and correcting various sources of error (source ENR variations, temperature variations, etc.). The test set provides a very good accuracy for both matched and mismatched devices, usually limited by source ENR accuracy and step attenuator repeat…
The clinical and molecular spectrum of QRICH1 associated neurodevelopmental disorder
2022
De novo variants in QRICH1 (Glutamine-rich protein 1) has recently been reported in 11 individuals with intellectual disability. The function of QRICH1 is largely unknown but it is likely to play a key role in the unfolded response of endoplasmic reticulum (ER) stress through transcriptional control of proteostasis. In this study, we present 27 additional individuals and delineate the clinical and molecular spectrum of the individuals (n=38) with QRICH1 variants. The main clinical features were mild to moderate developmental delay/intellectual disability (71%), non-specific facial dysmorphism (92%) and hypotonia (39%). Additional findings included poor weight gain (29%), short stature (29%)…
Gain scheduling automatic landing system by modeling Ground Effect
2014
Taking ground effect into account a longitudinal automatic landing system is designed. Such a system will be tested and implemented on board by using the Preceptor N3 Ultrapup aircraft which is used as technological demonstrator of new control navigation and guidance algorithms in the context of the “Research Project of National Interest” (PRIN 2008) by the Universities of Bologna, Palermo, Ferrara and the Second University of Naples. A general mathematical model of the studied aircraft has been built to obtain non–linear analytical equations for aerodynamic coefficients both Out of Ground Effect and In Ground Effect. To cope with the strong variations of aerodynamic coefficients In Ground …
