Alteraciones de la Conducta Alimentaria en Pacientes con Trastorno por Abuso de Sustancias
2018
Psychiatric eating disorders (ED) and substance use disorder (SUD) are frequent comorbidities and negatively affect evaluation, treatment, and prognosis of both pathologies. The aim of the present study was to determine the prevalence of eating disorders amongst patients seeking treatment for SUD, mainly alcohol, cocaine, and cannabis, and the modulating role of impulsivity and the presence of the eating restriction disorder. We employed the following evaluation instruments: the Barratt impulsivity scale, the eating disorder inventory (EDI), and the Valencia Addiction to Eating Restriction Questionnaire (CVAR). The results showed that patients with a SUD had higher levels of impulsivity and…
Alterations in eating behavior in patients with substance abuse disorders
2018
RESUMEN La comorbilidad psiquiátrica entre los trastornos de la conducta alimentaria (TCA) y los trastornos por uso de sustancias (TUS) suele darse con frecuencia, complicando el tratamiento y pronóstico de ambos. En el presente trabajo se estudió la prevalencia de los trastornos alimentarios en pacientes que demandan tratamiento por un TUS, principalmente alcohol, cocaína y cannabis, así como el papel modulador de la impulsividad y la adicción a la restricción alimentaria. Los instrumentos utilizados fueron la escala de impulsividad de Barratt, el Inventario de Trastornos Alimenticios (EDI) y el Cuestionario Valencia de Adicción a la Restricción (CVAR). Los resultados muestran que los paci…
The role of depression and impulsivity in the psychopathology of bulimia nervosa.
2013
Introduction: The study aimed to analyze the role of depression and impulsivity in the psychopathology of bulimia nervosa (BN). Materials and methods: Seventy female patients with DSM-IV BN, purging subtype, were assessed for eating-related symptoms, body dissatisfaction, affective symptoms, impulsivity, and personality traits. Factor analysis and structural equation modeling methods were used for statistical analysis. Results: BN appeared as a condition which incorporated 5 general dimensions: a) binge eating and compensatory behaviours; b) restrictive eating; c) body dissatisfaction; d) dissocial personality traits; and e) a cluster of features which was called "emotional instability" The…
Il Paradigma della Città Fluida
2013
Nella recente crisi globale i poderosi flussi di capitali finanziari, sociali e relazionali che hanno alimentato la riqualificazione urbana nel corso degli ultimi quindici anni non sono più disponibili ad essere intercettati in maniera indiscriminata così come è stato possibile fino a qualche anno fa. Nell'era della crisi strutturale le città più dinamiche non sono più quelle in grado di attrarre progetti urbani iconici ed investitori spinti dal mercato immobiliare o dalla redditività delle attività ricreative, ma quelle città che, a partire dalle loro profonde e diversificate risorse culturali, saranno capaci di attuare una vera e propria “metamorfosi” per usarle come base per la creazione…
In situ study of the sintering of a lead phosphovanadate in an Environmental Scanning Electron Microscope
2011
cited By 3; International audience; The in situ sintering of a powder of Pb3(VO4) 1.6(PO4)0.4 composition was performed in an Environmental Scanning Electron Microscope. The electric current induced by the electron beam was found to reduce the effective temperature of sintering as well as to accelerate the kinetics of shrinkage of a cluster composed of sub-micrometric grains of material. The presence of the residual current flow in the cluster during observation for in situ experiments helps to reduce the apparent sintering temperatures from 50 to 150 °C compared to conventional heating conditions without current. © 2011 Elsevier B.V.

Straight Access to Indoles from Anilines and Ethylene Glycol by Heterogeneous Acceptorless Dehydrogenative Condensation.
2017
The development of original strategies for the preparation of indole derivatives is a major goal in drug design. Herein, we report the first straight access to indoles from anilines and ethylene glycol by heterogeneous catalysis, based on an acceptorless dehydrogenative condensation, under noninert conditions. In order to achieve high selectivity, a combination of Pt/Al2O3 and ZnO have been found to slowly dehydrogenate ethylene glycol generating, after condensation with the amine and tautomeric equilibrium, the corresponding pyrrole-ring unsubstituted indoles.
Study of TiO2 nanomembranes obtained by an induction heated MOCVD reactor
2015
Abstract Nanostructures of TiO2 were grown using the metal oxide chemical vapor deposition (MOCVD) technique. The procedure used induction heating on a graphite susceptor. This specific feature and the use of cobalt and ferrocene catalysts resulted in nanomembranes never obtained by common MOCVD reactors. The present study discusses the preparation of TiO2 nanomembranes and the dependence of nanomembrane structure and morphology on growth parameters.

Abstract Bei der Umsetzung von rac. Methylphenylphosphinsaure-halogenide-nund pseudohalogeniden MePhP(O)X (X = F, Cl, CN, OC6H4NO2(p)) mit Alkoholen ROH (R = Me, PhCH2, CF3CH2 und i-Prop.) in Gegenwart der optisch aktiven Amine 1 bis 5 entstehen partiell optisch aktive Ester mit einer optischen Induktion von 1 bis 14%. Ein Mechanismus, der uber funf- bzw. sechsbindige Phosphorzwischenprodukte ablauft. wird vorgeschlagen. The Reaction of rac. methylphenylphosphinicacid-halides and pseudohalides MePhP(O)X (X = F, Cl, CN, OC6H4NO2(p)) with alcohols ROH (R = Me, PhCH2, CF3CH2 and i-Prop) leads in the presence of the optically active amines 1-5 to partial optically active esters. The optical ind…
Mononuclear Complexes of Iron(II) Based on Symmetrical Tripodand Ligands: Novel Parent Systems for the Development of New Spin Crossover Metallomesog…
2011
The synthesis and characterization of a series of mononuclear tripodand-based FeII complexes by means of Mossbauer andUV/Vis spectroscopic as well as magnetic methods is reported. The complexes were obtained from the reactions of FeII salt with heterocyclic aldehydes (imd = imidazole-4(5)-carboxaldehyde, py = picolinaldehyde, or 6-Mepy = 6-methylpicolinaldehyde) and a symmetric triamine [tren = tris(2-aminoethyl)amine, tame = 2,2,2-tris(aminomethyl)ethane, or tach = 1,3,5-cis,cis-cyclohexanetriamin]. Because of extreme rigidity of the capping triamine tach, the molecular structure of {Fe[tach(imd)3](BF4)2} (1) features an unprecedented tapered trigonal prismatic FeN6 polyhedron. The molecul…
Influence of the chain length and metal : ligand ratio on the self-organization processes of Cu2+ complexes of [1 + 1] 1H-pyrazole azamacrocycles
2020
Three new [1 + 1] macrocycles formed by the reaction of 1H-3,5-bis(chloromethyl)pyrazole with the tosylated amines 1,4,7,10-tetraazadecane (L1), 1,4,8,11-tetraazaundecane (L2) and 1,5,10,14-tetraazatetradecane (L3) are described. Potentiometric studies and HR-ESI-Mass spectrometry show the formation of dimeric binuclear Cu2+ complexes whose organization depends on the type of hydrocarbon chains connecting the amine groups. Furthermore, trinuclear or/and tetranuclear complexes are formed depending also on the length of the polyaminic bridge and on the sequence of the hydrocarbon chains. The crystal structures of the [2 + 2] [Cu2(H(H−1L2))2](ClO4)4·4H2O (1) and [Cu2(H−1L2)2](ClO4)2 (2) comple…
