Sulla natura giuridica del nuovo canone patrimoniale di concessione, autorizzazione o esposizione pubblicitaria
2020
La centralità della nozione di tributo quale criterio di riparto della giurisdizione costringe l’interprete ad indagare se il prelievo coattivo, quand’anche il legislatore non lo qualifichi né come imposta, né come tassa, né come contributo, presenti o meno i caratteri del tributo. Attraverso gli strumenti offerti dalla giurisprudenza della Corte costituzionale lo studio analizza le norme contenute nell’art.1, commi da 816 a 836, della L. n.160/2019, con cui il legislatore ha stabilito che i Comuni, le Province e le Città metropolitane istituiscono a decorrere dal 1° gennaio 2021, in sostituzione di forme di prelievo preesistenti, il nuovo canone patrimoniale di concessione, autorizzazione …
Prenatal air pollution exposure and growth and cardio-metabolic risk in preschoolers
2020
Objectives: We investigated the association between outdoor air pollutants exposure in the first trimester of pregnancy, and growth and cardio-metabolic risk at four years of age, and evaluated the mediating role of birth weight. Methods: We included mother-child pairs (N = 1,724) from the Spanish INMA birth cohort established in 2003-2008. First trimester of pregnancy nitrogen dioxide (NO2) and fine particles (PM2.5) exposure levels were estimated. Height, weight, waist circumference, blood pressure, and lipids were measured at four years of age. Body mass index (BMI) trajectories from birth to four years were identified. Results: Increased PM2.5 exposure in the first trimester of pregnanc…
Occupational exposure to environmental pollutants: evaluation of long-term effects on a group of newsagents in the city of Palermo
2012
Environmental pollution constantly threatens the health of urban populations. This problem of environmental hygiene takes a particular interest in Occupational Medicine, whereas some tasks take place mostly outdoors, so the airborne pollutants and noise can be considered as occupational hazards. The subject of this study is to evaluate the health of a group of newsagents in the city of Palermo, in relation to the level of urban pollution and noise monitored in ten years (2000-2010). It was assessed lung function, hearing, kidney, liver and cardiovascular systems, with particular reference to endothelial structures. Analysis of the results show the high prevalence of damage to the carotid di…
Induction of neuronal plasticity during adulthood. Role of cortical interneurons and plasticity-related molecules.
2019
La complejidad del sistema nervioso de los vertebrados representa un reto a la hora de conocer su funcionamiento. Hace ya más de cien años que se postuló la neurona como unidad básica de procesamiento, generación y transmisión de la información a través de este sistema, y, con el paso de los años, ha evolucionado el conocimiento sobre esta unidad funcional. La idea clásica del sistema nervioso central (SNC) adulto es la de un tejido asombrosamente interconectado y complejo, pero prácticamente inmutable y muy poco adaptable a los cambios. No obstante, esta visión se ha ido desplazando, formándose una nueva idea del SNC adulto que, aunque de manera más limitada que durante el desarrollo, tamb…
Intergenerational Effect of Early Life Exposure to Permethrin: Changes in Global DNA Methylation and in Nurr1 Gene Expression
2015
Environmental exposure to pesticides during the early stages of development represents an important risk factor for the onset of neurodegenerative diseases in adult age. Neonatal exposure to Permethrin (PERM), a member of the family of synthetic pyrethroids, can induce a Parkinson-like disease and cause some alterations in striatum of rats, involving both genetic and epigenetic pathways. Through gene expression analysis and global DNA methylation assessment in both PERM-treated parents and their untreated offspring, we investigated on the prospective intergenerational effect of this pesticide. Thirty-three percent of progeny presents the same Nurr1 alteration as rats exposed to permethrin i…

Cold Exposure Affects Lipid Metabolism, Fatty Acids Composition and Transcription in Pig Skeletal Muscle
2021
Cold exposure promotes glucose oxidation and modulates the lipid metabolism in adipose tissue, but it is still not fully clear whether cold exposure could affect meat quality and fatty acid metabolism in skeletal muscle of pig in vivo. Here, we kept finishing pigs under cold or room temperature overnight and determined the effects of cold exposure on meat quality, fatty acids composition and transcriptional changes in skeletal muscle of pigs. We found that cold exposure significantly reduced the meat colour24 h and pH24 h, without affecting carcass characteristics and other meat quality traits. Considerable changes were found in the proportions of individual fatty acids and the total conten…
Assessment of occupational exposure to pesticides in Spain through a job-exposure matrix (MatEmESp, 1996-2005)
2014
Introducción: La exposición laboral a plaguicidas ha sido asociada a numerosos problemas de salud. Sin embargo, la información sobre la exposición de los trabajadores afectados en España es escasa y dispersa. Objetivos: El objetivo de este trabajo fue estimar el nivel y la prevalencia de la exposición laboral a plaguicidas en España para el periodo 1996-2005, como parte del proyecto de construcción de la matriz empleo-exposición española, MatEmESp. Métodos: El establecimiento de las ocupaciones expuestas, los agentes de referencia y las estimaciones de exposición se basó en información de otras matrices, datos de evaluaciones de riesgos en empresas españolas y revisión de la bibliografía. R…

Prenatal exposure to diazepam and alprazolam, but not to zolpidem, affects behavioural stress reactivity in handling-naïve and handling-habituated ad…
2002
A gentle long-lasting handling produces persistent neurochemical and behavioural changes and attenuates the impairment in the behavioural reactivity to novelty induced by the prenatal exposure to diazepam (DZ) in adult male rat progeny. This study investigated the consequences of a late prenatal treatment with three GABA/BDZ R agonists (DZ) alprazolam (ALP) and zolpidem (ZOLP)), on different stress-related behavioural patterns, in non-handled (NH), short-lasting handled (SLH) and long-lasting handled (LLH) adult male rats exposed to forced swim test (FST), acoustic startle reflex (ASR) and Vogel test (VT). The effects on motor activity were evaluated in the open field and in the Skinner box…
