Mecanismos de transporte y toxicidad intestinal de especies de mercurio presentes en los alimentos
2014
El mercurio es un metal tóxico ampliamente distribuido en el medioambiente. Las formas químicas mayoritarias en los alimentos son el mercurio mercúrico [Hg(II)] y el metilmercurio (CH3Hg). La principal vía de exposición para el ser humano la constituye la dieta, siendo los productos pesqueros los que mayor aporte de mercurio realizan. Teniendo en cuenta que la principal vía de exposición al mercurio es la oral, el tracto gastrointestinal se considera la puerta de entrada de este tóxico al organismo. Estudios in vivo han demostrado que el Hg(II) presenta una moderada absorción (2-38%) mientras que el CH3Hg es absorbido prácticamente en su totalidad. Aunque se conocen los ratios de absorción …
Città nella ricostruzione ... e il Belice?
2008
Il testo parte da un esame delle vicende del dopoguerra nel Sud Italia con particolari riferimenti alla Basilicata (i Sassi di Matera) e alla Sicilia (Trappeto, Partinico e Danilo Dolci). Descrive poi la stato in cui versava il Belice negli anni ’60 prima e dopo il terremoto e costruisce un confronto con la realtà attuale. Molte cose appaiono modificate. Innanzi tutto dalla produzione prevalentemente cerealicola si è passati ad una produzione vitivinicola. La popolazione presente si è ridotta di poco distribuendosi differentemente, ovvero occupando i comuni di costa, ovvero quelli che sono riusciti a modificare la loro struttura produttiva. Emerge con chiarezza che le piccole centralità nel…

TRATTAMENTO PERCUTANEO ECOGUIDATO ( TPE) COMBINATO A PERCORSO FISIOCHINESITERAPICO NELLA GESTIONE DELLA TENDINOPATIA CALCIFICA DI SPALLA : L'ESPERIEN…
2019
Introduzione Le tendinopatie della cuffia dei rotatori sono le più comuni cause di dolore alla spalla, con una prevalenza nella popolazione generale stimata tra il 5 e il 39%. Tra le tendinopatie, un ruolo importante è occupato dalla tendinopatia calcifica. La frequenza della tendinopatia calcifica varia, sulla base degli studi presenti sinora in letteratura, tra il 7.5 e il 22% di tutti i casi di tendinopatia.(1,2,3). Nel trattamento della patologia calcifica di spalla si sono diffuse nel corso degli ultimi anni alcune importanti tecniche non invasive e mini-invasive che consentono spesso una risoluzione della patologia in tempi brevi e senza il ricorso al trattamento chirurgico. In partic…
Weight Reduction Behaviors Among European Adolescents : Changes From 2001/2002 to 2017/2018
2020
Purpose The purpose of this study was to analyze changes in the prevalence of weight reduction behaviors (WRBs) among European adolescents from 26 countries between 2001/2002 and 2017/2018. The impact of the perception of body weight on WLB was also analyzed, with particular attention being paid to overestimation. Methods The data of 639,194 European adolescents aged 11, 13, and 15 years who participated in the Health Behaviour in School-aged Children survey were analyzed. Age-standardized prevalence rates of WRB were estimated separately by survey round and gender for each country, using the overall 2017/2018 Health Behaviour in School-aged Children study population as the standard. Multiv…
Gender Trends in Tourism Destination
2013
Abstract The tourism experience was perceived traditionally in terms of products, destinations and consumption patterns. The “new mobility turn” sees the holiday experience as “performance”, “surveillance”, “play”, relationships “at-a-distance”, the impermanence of “sandcastles”, place making, etc. Gale (2007) stated five principles of this turn in tourism: it studies the mobility of individuals; it acknowledges material and immaterial structures; it deals with immobility and power relations; it recognizes virtual and imaginative forms of mobility; and it is concerned with environmental and global consequences. Destinations are not perceived now as fixed unities but as“sandcastles” made of …
Trends in perceived school stress among adolescentsin five Nordic countries 2002–2014
2019
Abstract Associations between school-related stress and poor health, risk behaviours and low well-being are well documented. The aim of this paper was to estimate trends of perceived school stress experienced by boys and girls of different ages in the Nordic countries, and to describe trends in school stress between the Nordic countries. Nordic data from the Health Behaviour in School-aged Children study (HBSC) between 2002 and 2014 were used. The participants were aged 11–16 years. School stress was measured by a single item; “How pressured do you feel by schoolwork?” The participants answering “some” or “a lot” were categorised as reporting school stress. Sweden, Norway and Denmark had …
Cross-national time trends in adolescent body weight perception and the explanatory role of overweight/obesity prevalence
2023
Introduction Body weight perception (BWP) is associated with health behaviors. Current evidence points to an increase over time in both actual and perceived weight status among adolescents, however there is limited evidence on time trends in BWP in cross-national samples of adolescents. Therefore, the aims of this study were to examine time trends in BWP between 2002 and 2018 among adolescents from 41 countries and regions, including gender and country differences and to explore the role of changes over time in country-level overweight/obesity prevalence in these trends. Methods Data were used from five cycles (2002, 2006, 2010, 2014, 2018) of the repeated cross-sectional Health Behavior in…
La representación social del medio rural: un análisis desde la geografía escolar
2019
La Tesis Doctoral analiza las representaciones sociales que 581 estudiantes de 3º ESO y 2º de Bachillerato de la provincia de Valencia (España) poseen acerca de los espacios rurales. Para ello se ha elaborado un cuestionario mixto cuyas preguntas siguen la trilogía espacial de Soja (2008) aplicadas a la didáctica de los espacios rurales, ya que la procedencia del alumnado se ajusta a tres áreas en el contexto geográfico de la provincia de Valencia de donde hemos seleccionado diez centros escolares: áreas rurales (Villar del Arzobispo, Requena, Càrcer y Villalonga de la Safor), periurbanas (Riba-roja de Túria, Paiporta y Torrent) y urbanas (Benimaclet y dos institutos de la ciudad de Valenci…
