Systematic review o f the Perforation Risk in S tenosing Eosinophilic Esophagitis: D ilation is much s afer than initially reported

Background a nd A ims: D ilation of stenosing EosinophilicEsophagitis (EoE) is considered a high-risk procedure asperforation rates o f up to 9% of patients h ave been reported.Goal: To systematically e valuate the dilation-associatedperforation risk in stenosing EoE.Methods: A systematic review of the literature was performedusing pubmed and Embase. Keywords used were "eosinophilicesophagitis", "dilation", "perforation", and "complications".Results: F rom 2002 to 2007 7 case s eries including 85patients r eported perforations i n 5 patients ( perforation r ate6%). The highest perforation rate was reported in a series of 36patients d ocumenting 3 perforations ( 9%). In 2 010 and 2011three large studies r eporting o n a total o f 404 patientsdocumented a perforation in 3 patients (0.74%). The perforationrate reported in small case series before 2010 was significantlyhigher compared to the r ates since 2 010 ( P <0.001). Theoverall p erforation frequency is 8 /489 patients (1.6%). Amedian of 3 endoscopic sessions with dilations were performedper patient, thereby leading to a perforation rate of 0.53% perendoscopy. Follow-up information on EoE p atients w ithperforation was available in 6 s tudies, all patients c ould bemanaged conservatively, dilation-associated mortality waszero.Conclusions: D ilation of stenosing EoE h as a m uch lowerperforation risk as r eported in e arlier c ase series. Theperforation rate per endoscopy (0.53%) is much lower than theone reported for d ilation of achalasia ( 2-4%). T aking intoaccount t he latest data, dilation of stenosing EoE c an beregarded as a safe procedure.

Aspectes econòmics de l'evolució del sistema públic d'ensenyament superior a Catalunya, 1985-1992

L'educació superior espanyola ha sofert un procés d'expansió generalitzat a partir de la segona meitat de la decada deis vuitanta. Malgrat aixo, aquesta expansió no pot ser analitzada conjuntament, ates que durant el mateix període es fan efectives les transferencies de competencies en materia d'educació a set comunitats autonomes que comencen a dur a terme polítiques universitaries no sempre concurrents. En aquest article abordarem el model catala d'expansió úniversitaria i el seu finançament, fent emfasi en els problemes derivats dé l'expansió i les seves possibles solucions. Per fer-ho, utilitzarem la següent estructura: en primer lloc, en l'apartat 2 es descriuen els elements basics del procés d'expansió (especialment la creació de les cinc noves universitats) i la situació resultant tal i com es presenta en l'actualitat. Sense aquestes descripcibns no cobrarien sentit les analisis més específiques sobre el finançament, que es presenten en els apartats 3 i 4.

Protective role of antioxidant vitamin E and catechin on idarubicin-induced cardiotoxicity in rats

Idarubicin is an anthracycline antibiotic extensively used in acute leukemia. In the present study we investigated whether vitamin E and catechin can reduce the toxic effects of idarubicin. Vitamin E (200 IU kg-1 week-1), catechin (200 mg kg-1 week-1), idarubicin (5 mg kg-1 week-1), idarubicin + vitamin E (200 IU kg-1 week-1), and idarubicin + catechin (200 mg kg-1 week-1) combinations were given to male Sprague-Dawley rats weighing 210 to 230 g (N = 6/group). Idarubicin-treated animals exhibited a decrease in body and heart weight, a decrease in myocardial contractility, and changes in ECG parameters (P<0.01). Catechin + idarubicin- and vitamin E + idarubicin-treated groups exhibited similar alterations, but changes were attenuated in comparison to those in cardiac muscle of idarubicin-treated rats (P<0.05). Superoxide dismutase and catalase activity was reduced in the idarubicin-treated group (P<0.05). Glutathione peroxidase levels were decreased in the idarubicin-treated group (P<0.05) and reached maximum concentrations in the catechin- and catechin + idarubicin-treated groups compared to control (P<0.01). Malondialdehyde activity was decreased in the catechin + idarubicin-treated groups compared to control and increased in the other groups, reaching maximum concentrations in the vitamin E-treated group (P<0.01). In electron microscopy studies, swelling of the mitochondria and dilatation of the sarcoplasmic reticulum of myocytes were observed in the idarubicin-treated groups. In groups that were given idarubicin + vitamin E and idarubicin + catechin, the only morphological change was a weak dilatation of the sarcoplasmic reticulum. We conclude that catechin and vitamin E significantly reduce idarubicin-induced cardiotoxicity in rats.

An investigation of ethylene inhibition of growth in etiolated Avena sativa coleoptiles /

Growth rates of etiolated Avena sativa coleoptiles in pH 7.0 buffered medium are stimulated in a synergistic manner by IAA and 320 ~l/l carbon dioxide. The suggestion that carbon dioxide stimulated growth involves dark fixation is supported by the ability of 1 mM malate to replace carbon dioxide, with neither factor able to stimulate growth in the presence of the other (Bown, Dymock and Aung, 1974). The regulation of Avena coleoptile growth by ethylene has been investigated in the light of this data and the well documented antagonism between carbon dioxide and ethylene in the regulation of developmental processes. The influence of various permutations of ethylene, IAA, carbon dioxide and malate on the rates of growth, l4c-bicarbonate incorporation, l4C-bicarbonate fixation, and malate decarboxylation have been investigated. In the presence of 320 ~l/l carbon dioxide, 10.8 ~l/l ethylene inhibited growth both in the absence and presence of 20 ~M IAA with inhibition times, of 8-10 and 12-13 minutes respectively. In contrast ethylene inhibition of growth was not significant in the absence of growth stimulation by CO2 or 1 mM malate, and the normal growth increases in response to CO2 and malate were blocked by the simultaneous application of ethylene. The rates of incorporation and dark fixation of l4C-bicerbonate were not measurably. influenced by ethylene, IAA or malate, either prior to or during the changes in growth ,ates induced by these agents. The data does not support the hypothesis that ethylene inhibition of growth results from an inhibition of dark fixation, but suggests that ethylene may inhibit a process which is subsequent to fixation.

Amplification of the DFR1 gene in Saccaromyces cerevisiae

A new system was employed to study amplification of t,he DHF'R gene DFB,1 ) in Sa<,:;charoillYCB§. .Q~~Yi...S!i<;1~. . This system consists of a series of yeast strains containing a casset,te which encodes t he yeast, D..ERl gene ttghtly linked tjO a f usion of the yeast 1EU2. regulat,ory region wi tJ1 the LAQZ str ctural gene from E. cO.1-1 (,) . M. Clement , unpubl i,::;hed) . Th's casset;t e was shown t.o be integrat,ed int o a unj que chromosomal l ocati on in each strain . Yeast cells were se l ected for MTX-resistance and overproduction of ~ galac t osi d se ( B-gal ). Since the inserted DF'Rl and ~ACZ genes are independently regulated, it was thought that cel l s with this phenotype probably contain e d ampl if ications of the cassette. A lar ge variat ion in the f requn y o f MTX-resistance was found between the di ff e r ent str ains. These freqlen c ~ es r anged from about 2 x 10 - 7 fo r a population of cells containing the cassette integrated at, the BI J2.l gene in t,he middle of the long arm of chromosome V, to about 5 x 10-4 for a strain with the cassette i nserted in the r DNA cluster Abo It 85% of the MTX- res i stcmt iso l ates examined showed enhanced B·-gal act i v ity rel a t ive t o the parental strain . For the ma jorit y of strains, the mean B- gal activity in drug-r sistant clones was about 3 times that o f the parent following a single se l ect i on step . I n con t r ast, primary MTX-resistant derivat~ves of cells with the cassette inserted 3 at the rDNA cluster showed inc r eases in B- gal activity ranging from 9 - 14 f old r elative to the parent. Analysis of the latte r s train by Southe rn hybr idization indicated that the cassette was inde e d amplified several fold in MTX-re sistant derivatives. A sing l e strain, in which the cassette was inserted at the !lEA;], loc u.s , was used to examine in more detai 1 , the parameters affecting DFRl gene amplificat~ion in yeast . The mean B- gal activity in drug-resistant derivatives of this strain could be increased from 3 to 6 or 7 fold relative to the parent, by stepwise sel ection using increasing MTX concentrations. B-gal overproduction was found to be un stable in all primary and highly -resistant isolates examined. There was no indication, h owever, of a decrease i n growth r a t e in MTX-res i s tant cells which overproduced B - gal.

Animación de los sistemas alternativos y aumentativos para alumnos gravemente afectados.

Proyecto desarrollado en el propio centro, dirigido a alumnos gravemente afectados y con plurideficiencia, cuyos objetivos más destacados son la unificación de los símbolos pictográficos y gestos utilizados en el mismo, así como la elaboración de materiales adaptados para los alumnos más afectados o que puedan tener dificultades de comprensión y/o expresión. La primera fase que ha sido la elaboración de los materiales se ha realizado por dos logopedas: unas veces de forma individual y otras de forma conjunta. Todo el trabajo se ha realizado en horas de exclusiva y sobre todo fuera del horario escolar. En la segunda fase han intervenido los tutores y se ha desarrollado a nivel individual con los alumnos y también de forma grupal y consistía en la manipulación y aprendizaje de los símbolos y gestos. La tercera fase: generalización y uso de los aprendizajes, se realizará el próximo curso e intervendrán todas las personas del centro: logopedas, Ates, fisioterapeutas. La valoración del proyecto ha sido altamente positiva, porque ha permitido unificar los símbolos y gestos de los distintos sistemas de comunicación que se utilizan en el centro.

Impacto en la calidad de la Inducción anestésica con premedicación en pacientes pediatricos

La inducción anestésica en niños es uno de los mayores retos para los anestesiólogos ya que es la fase más estresante del período perioperatorio para el paciente pediátrico. Existen diferentes intervenciones para minimizar la ansiedad perioperatoria y aumentar la cooperación del paciente pediátrico con la inducción anestésica. Entre las intervenciones exitosas la premedicación farmacológica con midazolam ha mostrado grandes beneficios en pacientes pediátricos. Metodología: Se realizó un estudio de casos y controles en pacientes pediátricos llevados a cirugía en la Fundación Cardioinfantil entre 2011-2014. Por medio de muestreo aleatorio por conveniencia se tomaron como casos pacientes con premedicación y controles pacientes sin premedicación. El éxito en la inducción se midió por medio de la escala ICC, usada a nivel mundial. Resultados: El promedio de edad fue 4.9 σ 3.01 años para los casos y 5.02σ3.2 años para controles, presentaron la misma distribución por género, 40.6% femenino, 59.3% masculino. El éxito de la inducción anestésica con midazolam mostró resultados significativos (OR 7.3 IC95% 4.3 – 12.5 p0,000), en hombres (OR 9.44 IC95%4.5 – 19.8 p0,000), en menores de 5 años (OR 10.33 IC95% 5.07 – 21.04 p0,000), en pacientes con antecedentes quirúrgicos (OR 12.2 IC95% 5.28 – 27.8 p0.000) o anestesias previas (OR 7.9 IC95% 4.4 – 14.4 p0,000). Discusión: El midazolam como agente farmacológico usado para premedicación en pacientes pediátricos presenta resultados exitosos contundentes, por lo cual debe usarse en todos los casos.

IMPASSES, DESAFIOS E BROTOS: O papel da Assessoria na Transição Agroecológica em Assentamentos Rurais

This thesis is the result of a study on the role of technical assistance in the process of agroecological transition, which are under way in rural settlements in the territory of Mato Grande, Rio Grande do Norte. Your goal is, from the Technical Assistance Program, Social and Environmental (ATES), launched in 2004 by INCRA understand to what extent this action accomplished their goal of doing a job with a focus on agroecology. To this end, we chose to work with a qualitative methodology, through interviews with settlers, advisors and representatives of INCRA. They also contributed to developing this thesis, the direct observations, which offer visits to settlements and advisory bodies in the Rede Pardal, apart from participation in meetings and activities in which they were being discussed the issues of advice, agroecology and rural settlements. The thesis is divided into five chapters, plus introduction and conclusion. The first three refer to a theoretical analysis and historical about the process of land reform, and as a result the establishment of rural settlements, the importance of peasant tradition for the design of agro-ecological design and the relationship between agricultural models and proposals advice to the countryside. In two subsequent chapters, there was a panoramic picture of the territory of Mato Grande, settlements and groups that make up this research, for then analyze the performance of advisory services in these settlements, with the parameter, agroecology. It was found that the advice in this perspective, suffers a series of constraints, causing a gap between the ideal proposed in the manual and the actual practiced in their daily lives. Still, it is concluded that the ATES has contributed to innovations in productive groups who are experiencing agroecological processes, which can be regarded as shoots for the transition to a new dynamic of development.

Destecendo uma carta pela estelística da expressão

We aim to analyse the text written by Eça de Queirós, “Carta ao Sr. Mollinet”, theorizing the stylistics of Marcel Cressot’s expression, called “the texture”. We discuss what is sought in the reading of a text nowadays: the form, the meaning or the form that produces meaning? Even though through stylistics there is identifi cation and description of the linguistic categories in the text, the morphological identifi cation in the enunciation level is emptied, if it is done separately. It is from the semantic-syntactic and melodic axes that Eça infl ates his characters with life. The characterization of Pacheco and Portuguese people is supported by the nexus, a producer of antagonistic meta-signifi cation in relation to the fi rst meaning. Eça’s irony results from the reverse meaning – from “ne pas dire”. The nexus is the great meaningful cohesion between logical and metalogic discourse – producing new signifi cations; multiplying verbal resources, which are created in order to metamorphose the linguistic sign into pictorial or iconic signs. The irony governs the whole constructive tessitura that stems from new referents, which result from demiurgical relations between themselves because of the metalogical process, as it allows to establish and change the direction when sign and referent, signifi er and signifi ed, utterance and context are related. The analysis of Eça’s selected text enriches the discoveries presented by the Stylistics of Expression.

Modelagem de um secador solar de produtos agrícolas com sistema de armazenagem de energia térmica

Nos países em desenvolvimento, como o Brasil, a secagem de produtos agrícolas com uso de secador solar representa uma alternativa promissora de baixo custo, reduzindo perdas e agregando valor aos produtos. Porém, devido à natureza periódica da radiação solar e das condições do tempo, nem sempre é viável sua utilização. Dessa forma, o objetivo do trabalho foi a modelagem de um sistema auxiliar de armazenagem de energia térmica (SAET) em um secador solar, cuja finalidade é armazenar energia durante o dia para ser utilizada conforme necessário. Com base em registros de temperatura e umidade relativa, ambas do ar, de um secador solar, foi feito um estudo da termodinâmica dos processos envolvidos, a fim de propor meios para o dimensionamento do SAET. Foram explorados a estimativa do fluxo de massa de ar no secador, a modelagem da temperatura em função da radiação, e o dimensionamento para diferentes modos de operação do SAET, considerando o sistema ideal. Este dimensionamento tratou tanto do caso de fornecimento contínuo de fluxo de água preaquecida, como de uso de automação para controlar o fluxo. A estimativa de fluxo de ar no secador se aproximou de valores típicos encontrados na literatura. O dimensionamento do sistema, embora considerado ideal, mostra que a utilização do SAET melhora o desempenho do secador, servindo como parâmetro para melhor compreender o comportamento das variáveis durante seu funcionamento.
