Estrategias territoriales participativas como instrumentos de diagnóstico y prospectiva, en el contexto europeo de los Fondos de Cohesión 2014–2020: el caso de Villena (Alicante)

Las Estrategias Territoriales de carácter participado, se han convertido en el instrumento válido para diagnosticar las necesidades de un territorio. La Unión Europea obliga la aplicación de esta herramienta en el nuevo contexto del periodo 2014–2020. En el municipio de Villena (Alicante), se realizó una estrategia territorial integrada, desde hace dos años que ha derivado en un foro económico social, a través del proceso de abajo-arriba. El estudio de caso avala que la ciudadanía sí que es importante y ha participado activamente en una planificación estratégica ya que los nuevos tiempos, en el contexto del desarrollo local, así lo determinan. Se establecen las fases de aplicación, la metodología utilizada y también los resultados obtenidos.

Dietary Fluoride Intake by Children Receiving Different Sources of Systemic Fluoride

There has been no comparison of fluoride (F) intake by pre-school children receiving more traditional sources of systemic F. The aim of this study was to estimate the dietary F intake by children receiving F from artificially fluoridated water (AFW-Brazil, 0.6-0.8 mg F/L), naturally fluoridated water (NFW-Brazil, 0.6-0.9 mg F/L), fluoridated salt (FS-Peru, 180-200 mg F/Kg), and fluoridated milk (FM-Peru, 0.25 mg F). Children (n = 21-26) aged 4-6 yrs old participated in each community. A non-fluoridated community (NoF) was evaluated as the control population. Dietary F intake was monitored by the ""duplicate plate"" method, with different constituents (water, other beverages, and solids). F was analyzed with an ion-selective electrode. Data were tested by Kruskall-Wallis and Dunn`s tests (p < 0.05). Mean (+/- SD) F intake (mg/Kg b.w./day) was 0.04 +/- 0.01(b), 0.06 +/- 0.02(a,b), 0.05 +/- 0.02(a,b), 0.06 +/- 0.01(a), and 0.01 +/- 0.00(c) for AFW/NFW/FS/FM/NoF, respectively. The main dietary contributors for AFW/NFW and FS/FM/NoF were water and solids, respectively. The results indicate that the dietary F intake must be considered before a systemic method of fluoridation is implemented.

Biomarkers of Fluoride in Children Exposed to Different Sources of Systemic Fluoride

There has been no comparison between fluoride concentrations in urine and nails of children exposed to different sources of systemic fluoride. The aim of this study was to compare the relationship between fluoride intake with urinary fluoride excretion and fluoride concentrations in fingernails and toenails of children receiving fluoride from artificially fluoridated water (0.6-0.8 mg F/L, n = 25), naturally fluoridated water (0.6-0.9 mg F/L, n = 21), fluoridated salt (180-200 mg F/Kg, n = 26), and fluoridated milk (0.25 mg F, n = 25). A control population was included (no systemic fluoride, n = 24). Fluoride intake from diet and dentifrice, urinary fluoride excretion, and fluoride concentrations in fingernails/toenails were evaluated. Fluoride was analyzed with an ion-selective electrode. Urinary fluoride excretion in the control community was significantly lower when compared with that in the fluoridated cities, except for the naturally fluoridated community. However, the same pattern was not as evident for nails. Both urinary fluoride output and fluoride concentrations in fingernails/toenails were significantly correlated to total fluoride intake. However, the correlation coefficients for fluoride intake and urinary fluoride output were lower (r = 0.28, p < 0.01) than those observed for fingernails/toenails (r = 0.36, p < 0.001), suggesting that nails might be slightly better indicators of fluoride intake at the individual level.

Avaliação da concentração de flúor em águas minerais comercializadas no Brasil

A utilização de flúor sistêmico deve ser controlada em termos de risco/benefício, pois enquanto a subdosagem não trouxer benefício anticárie, a sobredosagem estará associada com fluorose dental. Assim, uma das preocupações é o consumo de águas minerais, o qual tem aumentado nos últimos anos. Deste modo, foi realizado estudo com o objetivo de analisar a concentração de flúor em águas minerais comercializadas no Brasil. Foram analisadas 104 marcas comerciais, de diferentes regiões do País. Utilizou-se eletrodo específico Orion 96-09 e analisador de íons Orion EA 940, previamente calibrados com soluções padrões de flúor. Foram observadas concentrações de flúor variando de 0,0 a 4,4 ppm. Constataram-se: 1) Concentrações significativas de flúor não relatadas pelo produtor; 2) Concentrações de flúor sem significado preventivo anti-cárie, embora o produtor destaque na embalagem "Água Mineral Fluoretada"; 3) Concentrações de flúor capazes de provocar fluorose dental severa, embora o produtor não faça nenhuma referência que o mesmo existe. Conclui-se ser necessário um Sistema de Vigilância Sanitária para o controle de flúor nas águas minerais oferecidas à população brasileira, quer seja em termos de benefício como de risco.

Descrição geral do Reino do Peru, em particular de Lima

Em 1970, o historiador peruano Guillermo Lohman Villena dava a conhecer ao público as suas pesquisas sobre a autoria da Descrição geral do Reino do Peru, em particular de Lima, que agora editamos, com uma solidez que torna até hoje muito credível a hipótese de o autor ser um cristão-novo português, chamado Pedro de León Portocarrero. De qualquer forma, este texto, escrito durante a primeira metade do século XVII, reflecte a experiência de muitos portugueses que no período da união das coroas ibéricas circularam pelo território andino, muitos deles dedicados ao comércio. Os artigos que acompanham a edição abordam esta circulação entre impérios, a partir de diferentes perspectivas, mostrando as relações que existiram entre os súbditos ibéricos, à margem da separação legal estabelecida em Tomar. O leitor interessado em aspectos como o comércio, a natureza do território peruano, a sua geografia e agricultura encontrará na Descrição... um manancial de informação muito pormenorizado, bem como sobre os diferentes grupos humanos que vivam e circulavam no Peru. A edição tem dois tipos de notas: por um lado, notas de carácter histórico, com o objectivo de esclarecer termos e conceitos próprios da história colonial peruana e hispano-americana e, por outro, comentários à tradução que pretendem chamar a atenção sobre peculiaridades linguísticas da Descrição... Por fim, editamos a transcrição de um documento relacionado com o processo inquisitorial que o autor sofreu, conservado no Arquivo Histórico Nacional de Madrid.

Fabricació de Lents Zonals de Fresnel per aplicació als raigs X tous

Estudi elaborat a partir d’una estada al Paul Scherrer Institut del Maig a l’Octubre del 2006 amb l’ajuda i supervisió dels Dr. Konstantins Jefimovs i Dr. Christian David. Focalitzar raigs X tous és una necessitat essencial per al microanàlisis, la microscopia, i fer imatges en moltes Instal·lacions de Radiació Sincrotró. Les Lents Zonals de Fresnel (FZP, de la denominació anglesa “Fresnel Zone Plates”) han demostrat donar uns punts focals amb una resolució espacial destacada i una baixa il·luminació de fons. Tanmateix, la fabricació de FZP és complexa i no totalment reproduïble. A més a més, el temps de vida de les FZP és força curt, ja que estant situades sobre membranes de nitrur de silici molt fines i altament absorbents. Per tant, hem fet esforços per implementar FZP de silici, que s’espera que siguin més resistents. L’element està fet d’una oblia de cristall de silici poc absorbent, i no presenta cap interfase entre materials. Així doncs, aquestes lents són especialment adequades per a aguantar les extremes càrregues de radiació de les fonts de raigs X més brillants. Particularment, això és molt important per a les aplicacions a les pròximes generacions de fonts de raigs X, com els Làsers d’Electrons Lliures (FEL, de la denominació anglesa “Free Electron Laser”). El silici també garanteix que no hi hagi cap banda d’absorció en el rang d’energies de la finestra de l’aigua (200-520 eV), fent aquestes lents ideals per a fer imatges de mostres biològiques. En aquest informe, hi ha una descripció detallada de tots els passos involucrats en la fabricació de les Lents Zonals de Fresnel de silici. En resum, les estructures de FZP es modelen sobre una resina utilitzant litografia per feix d’electrons i llavors el patró es transmet al silici mitjançant un gravat d’ions reactius (RIE, de la denominació anglesa ‘Reactive Ion Etching’) utilitzant una fina (20 nm) màscara de Crintermitja. Les membranes de silici es poden aprimar després de la fabricació de les estructures per a garantir una transmissió suficient fins i tot a baixes energies. Aquest informe també inclou l’anàlisi i la discussió d’alguns experiments preliminars per avaluar el rendiment de les Si FZPs fets a la línia de llum PolLux del Swiss Ligth Source amb l’ajuda dels Dr. Jörg Raabe i Dr. George Tzvetkov.

Treball de recerca: tant tu com jo

Treball de recerca realitzat per alumnes d’ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit científic del Jovent l’any 2008. La pastilla anticonceptiva masculina és un producte químicament possible però encara no llençat al mercat. El motiu de la recerca ha estat investigar per comprovar si el disseny d’una campanya de màrqueting tindria èxit en la promoció d’aquest producte. En primer lloc, s’ha dut a terme una recerca teòrica sobre l’anticoncepció i el màrqueting. En segon lloc, s’ha realitzat un treball de camp en dues parts. D’una banda s’han confeccionat enquestes avaluant l’acceptació del producte en la població. De l’altra s’han realitzat entrevistes a professionals: sexòleg-psicòleg, ginecòleg, publicista i farmacèutica.Posteriorment s’ha dissenyat la campanya de màrqueting, gravat l’espot televisiu i dissenyat una pàgina web.

Models i formes de la pintura catalana del Barroc: el mirall de l'art francès

Estudi elaborat a partir d’una estada a l’Institut National d'Histoire de l'Art- Bibliothèque Nationale de France entre l'1 i el 31 de juliol de 2007. S’ha treballat en la recerca documental sobre les relacions artístiques entre França i Catalunya a l’Època Moderna. Els materials o fons documentals d’interès han estat dos: els fons gràfics d’estampes i gravats de la Bibliothèque Nationale, no tant en el sentit de consulta dels originals –que en alguna ocasió també- com sí en el la visualització de les vastíssimes fototeques, que ha permès a l’autor aplegar un bon nombre d’imatges que en el futur serviran per posar en relació la cultura figurativa francesa –sobretot de la pintura i de l’escultura, però també de la tractadística arquitectònica- amb la catalana de l’època, ja sigui per constatar les semblances com per fer notar les diferències en els usos dels models figuratius. S’ha buidat material bibliogràfic difícil de localitzar a Catalunya. Són publicacions referides a gravat, d’una banda, i a patrimoni artístic. Aquest darrer aspecte s’ha treballat des de dos vessants: en seguir notícies de la presència d’artistes catalans a França i viceversa, i en buscar dades sobre l’espoli d’obres d’art portat a terme a Catalunya durant el període napoleònic.

Exercise induces rapid interstitial lung water accumulation in patients with chronic mountain sickness.

BACKGROUND: Chronic mountain sickness (CMS) is a major public health problem in mountainous regions of the world. In its more advanced stages, exercise intolerance is often found, but the underlying mechanism is not known. Recent evidence indicates that exercise-induced pulmonary hypertension is markedly exaggerated in CMS. We speculated that this problem may cause pulmonary fluid accumulation and aggravate hypoxemia during exercise. METHODS: We assessed extravascular lung water (chest ultrasonography), pulmonary artery pressure, and left ventricular function in 15 patients with CMS and 20 control subjects at rest and during exercise at 3,600 m. RESULTS: Exercise at high altitude rapidly induced pulmonary interstitial fluid accumulation in all patients but one (14 of 15) with CMS and further aggravated the preexisting hypoxemia. In contrast, in healthy high-altitude dwellers exercise did not induce fluid accumulation in the majority of subjects (16 of 20) (P = .002 vs CMS) and did not alter arterial oxygenation. Exercise-induced pulmonary interstitial fluid accumulation and hypoxemia in patients with CMS was accompanied by a more than two times larger increase of pulmonary artery pressure than in control subjects (P < .001), but no evidence of left ventricular dysfunction. Oxygen inhalation markedly attenuated the exercise-induced pulmonary hypertension (P < .01) and interstitial fluid accumulation (P < .05) in patients with CMS but had no detectable effects in control subjects. CONCLUSIONS: To our knowledge, these findings provide the first direct evidence that exercise induces rapid interstitial lung fluid accumulation and hypoxemia in patients with CMS that appear to be related to exaggerated pulmonary hypertension. We suggest that this problem contributes to exercise intolerance in patients with CMS. TRIAL REGISTRY: ClinicalTrials.gov; No.: NCT01182792; URL: www.clinicaltrials.gov.

How to avoid gender bias in classroom interaction? A cooperative learning experience

This project aims to analyse the kind of questions the teacher asks students in order to encourage them to participate in her classes. Consequently, the researcher has read relevant literature and has analysed a short excerpt of a video recorded during her first practicum. She has also analysed a number of activities carried out during her second practicum in order to find out if she had improved her questioning skills in the classroom

Cooperative learning in the ESL classroom

This research explores the advantages and disadvantages of collaborative learning departing from two different methodological studies. In the first one, we will go deep into the reflections about group work of a student-teacher in her first experiences during a two months practicum in Sabadell's Emily Bronte. In the second one, we will analyze in a more empirical way the interaction that takes place among a trio of students engaged in a question-answering task about a text based on a three minutes vignette recorded on January 2010

Detection of Toxoplasma gondii oocysts in water: proposition of a strategy and evaluation in Champagne-Ardenne Region, France

Water is a vehicle for disseminating human and veterinary toxoplasmosis due to oocyst contamination. Several outbreaks of toxoplasmosis throughout the world have been related to contaminated drinking water. We have developed a method for the detection of Toxoplasma gondii oocysts in water and we propose a strategy for the detection of multiple waterborne parasites, including Cryptosporidium spp. and Giardia. Water samples were filtered to recover Toxoplasma oocysts and, after the detection of Cryptosporidium oocysts and Giardia cysts by immunofluorescence, as recommended by French norm procedure NF T 90-455, the samples were purified on a sucrose density gradient. Detection of Toxoplasma was based on PCR amplification and mouse inoculation to determine the presence and infectivity of recovered oocysts. After experimental seeding assays, we determined that the PCR assay was more sensitive than the bioassay. This strategy was then applied to 482 environmental water samples collected since 2001. We detected Toxoplasma DNA in 37 environmental samples (7.7%), including public drinking water; however, none of them were positive by bioassay. This strategy efficiently detects Toxoplasma oocysts in water and may be suitable as a public health sentinel method. Alternative methods can be used in conjunction with this one to determine the infectivity of parasites that were detected by molecular methods.

Tumor microenvironment and immune effects of antineoplastic therapy in lymphoproliferative syndromes.

Lymphomas represent a wide group of heterogenic diseases with different biological and clinical behavior. The underlying microenvironment-specific composition seems to play an essential role in this scenario, harboring the ability to develop successful immune responses or, on the contrary, leading to immune evasion and even promotion of tumor growth. Depending on surrounding lymphoid infiltrates, lymphomas may have different prognosis. Moreover, recent evidences have emerged that confer a significant impact of main lymphoma's treatment over microenvironment, with clinical consequences. In this review, we summarize these concepts from a pathological and clinical perspective. Also, the state of the art of lymphoma's anti-idiotype vaccine development is revised, highlighting the situations where this strategy has proven to be successful and eventual clues to obtain better results in the future.

Immune Microenvironment in Colorectal Cancer: A New Hallmark to Change Old Paradigms

Impact of immune microenvironment in prognosis of solid tumors has been extensively studied in the last few years. Specifically in colorectal carcinoma, increased knowledge of the immune events around these tumors and their relation with clinical outcomes have led to consider immune microenvironment as one of the most important prognostic factors in this disease. In this review we will summarize and update the current knowledge with respect to this intriguing and complex new hallmark of cancer, paying special attention to infiltration by T-infiltrating lymphocytes and their subtypes in colorectal cancer, as well as its eventual clinical translation in terms of long-term prognosis. Finally, we suggest some possible investigational approaches based on combinatorial strategies to trigger and boost immune reaction against tumor cells.
