Sealing ability of castor oil polymer as a root-end filling material

OBJECTIVE: The purpose of this study was to evaluate the sealing ability of castor oil polymer (COP), mineral trioxide aggregate (MTA) and glass ionomer cement (GIC) as root-end filling materials. Forty-five single-rooted human teeth were cleaned and prepared using a step-back technique. The apical third of each root was resected perpendicularly to the long axis direction. All teeth were obturated with gutta-percha and an endodontic sealer. After, a root-end cavity with 1.25-mm depth was prepared using a diamond bur. The specimens were randomly divided into three experimental groups (n=15), according to the root-end filling material used: G1) COP; G2) MTA; G3) GIC. The external surfaces of the specimens were covered with epoxy adhesive, except the root-end filling. The teeth were immersed in rhodamine B dye for 24 hours. Then, the roots were sectioned longitudinally and the linear dye penetration at the dentin/material interface was determined using a stereomicroscope. ANOVA and Tukey's tests were used to compare the three groups. The G1 group (COP) presented smaller dye penetration, statistically different than the G2 (MTA) and G3 (GIC) groups (p;0.05). The results of this study indicate that the COP presented efficient sealing ability when used as a root-end filling material showing results significantly better than MTA and GIC

Programa mais educação: relato de experiência em uma Escola Municipal de SJP/PR / Program more education: report of experience in a Municipal School of SJP/PR

O Programa Mais educação é uma prática realizada em escolas públicas com estudantes do 2° ao 5° ano do período integral, no qual consiste em atividades lúdicas, como: o meio ambiente, esporte, lazer, cultura e artes. O objetivo do presente artigo é descrever como funciona o Programa Mais Educação em relação às hortas comunitárias na Escola Municipal Cleonice Braga Fonseca, localizada em São José dos Pinhais. Para isso, foram utilizados os seguintes métodos de pesquisa: pesquisa bibliográfica, pesquisa de campo e pesquisa descritiva. Como resultados, foi observada a importância da horta na educação dos estudantes, influenciando na melhoria de hábitos alimentares, na qualidade de vida dos mesmos e no aprendizado recorrente a assuntos ambientais e econômicos, uma vez que os estudantes veem na pratica o uso consciente do dinheiro na melhoria da escola, e a importância do aproveitamento dos alimentos que não se destinam a venda, o Programa também gera um aprendizado significativo para a vida do aluno e socialização do mesmo, pois trata de assuntos como respeito, saúde, dignidade, convivência com a família e sociedade. Conclui-se que o programa mais educação contribui para o meio ambiente, uma vez que desenvolve nos estudantes a consciência ambiental e também uma inovação na educação das deles, destacando as escolas que adotam o programa das demais.

Quality and safety conditions of flocked oats (Avena sativa L.) stored in bags: Poster

Oats (Avena sativa L.) have reached the healthy food market worldwide due to its special nutrients composition and fiber high quality. Therefore, quality & safety control is a must, both during the storage and commercialization stages. The current study evaluated the physicochemical characteristics (flakes size/variation %, pH, moisture content-mc, water activity-aw), living organisms (insects & mites / mycoflora - fungi load& genera identification), mycotoxins(ochratoxin A – OTA / zearalenone – ZON / aflatoxins – AFLs / esterigmatocistin – EST)andthe storage conditions of flocked oats stored inbags.Regarding the oats physicochemical characteristics, flakes particle size varied, however most of the samples present size uniformityand only one sample had high percentage of residue. That indicates high insects and other living organisms activity (consumption / proliferation) of oats starch and other nutrients. The analysis through stereomicroscope showed intense presence of insects and mites. Samples were seen also sheltering those living organisms (27%), which are not allowed by regulation (no soils, parasites and larvae presence). As expected, mc (10.8-13.2%) and/or aw (0.61-0.90) varied, however they kept on the safer levels (< 13% / 0.90) insects/mites and fungi growth wise. With respect to pH, it varied from4.1to 5.85, indicating some rancidity/fermentation reactions taking place, thus changes in organoleptic parameters. The total fungi load ranged from 3x102 to 1.29x105 CFU/g, with Aspergillus and Rhizopusthe genera more identified. Only one sample was toxin contaminated (OTA - 80 µg/kg). Insects are known vectors of fungal spores and can spread their hyphae on their dead/live skeleton, apart from mites that can trigger allergies in humans and animals. Therefore, current data demonstrate that despite the storage conditions control application, living organisms can occur in flocked oats (stored in bags) and it is necessary to apply decontamination methods to control/prevent their proliferation.Oats (Avena sativa L.) have reached the healthy food market worldwide due to its special nutrients composition and fiber high quality.

Abordagem do lactente com queixa de nausea e vomito

Náuseas e vômitos podem ser causados por uma ampla gama de condições que afetam vários sistemas de órgãos diferentes, com implicações de saúde muito diferentes. Os objetivos da avaliação são identificar rapidamente condições graves para as quais é necessária uma intervenção imediata e, em seguida, identificar uma causa específica dos sintomas para orientar o manejo. As causas do vômito variam de acordo com a idade na apresentação.  Em muitos casos, a causa das náuseas e vômitos pode ser determinada a partir da história e do exame físico. O diagnóstico diferencial é informado pela idade da criança e se as náuseas e vômitos são agudos, crônicos ou episódicos

Ações do Grupo de Apoio Pedagógico (GAP) em prol do ensino de graduação da Faculdade de Zootecnia e Engenharia de Alimentos (FZEA)

This report presents the activities performed by GAP-FZEA during the period of 2005 to 2016 and their impact on the occupation of FZEA teachers in relation to teaching/learning process. Before the creation of Course Coordinating Committees (CoCs), the GAP-FZEA helped the FZEA teachers to draw the professional profile of Higher Education students and also helped them to think about their own pedagogical formation. After the CoCs creation, besides the GAP-FZEA was continuing to work in direction to pedagogical formation of the teachers, they mainly focus on helping the CoCs of FZEA in thinking about the construction of PoliticalPedagogical Project (PPP). Later, the GAP-FZEA promoted the I Simpósio de Graduação da FZEA, which give to teachers the opportunity to exchange experiences regarding to pedagogical management and practice. The GAP-FZEA provides favorable conditions to congregate the teachers by stimulating the discussion about teaching/learning process.O presente relato apresenta as ações exercidas pelo GAP-FZEA durante o período de 2005 a 2016 e o seu impacto nas atividades desenvolvidas pelos docentes da FZEA pertinentes ao ensino de graduação. Antes da criação das Comissões Coordenadoras de Curso (CoCs), o GAP-FZEA atuou diretamente na promoção de eventos sobre gestão pedagógica dando subsídios aos docentes para que os mesmos refletissem sobre a necessidade de traçar o perfil profissional do estudante e sobre sua própria formação pedagógica. Após a criação das CoCs, o GAPFZEA, além de continuar trabalhando na formação pedagógica dos docentes da FZEA, atuou indiretamente na gestão pedagógica dando subsídios às CoCs da FZEA para que as mesmas reflitam sobre a construção dos Projetos Políticos Pedagógicos (PPPs). Posteriormente, o GAP-FZEA promoveu o I Simpósio de Graduação da FZEA, que permitiu a troca de experiências vivenciadas pelos docentes da FZEA quanto à gestão e à prática pedagógica. O GAP-FZEA mostrou que pode propiciar espaços para congregar os docentes e estimular o debate sobre as práticas de ensino-aprendizagem na construção desse ambiente de aprimoramento
