5. Análise da desinfecção apical do canal radicular preparado em três diferentes comprimentos de trabalho, utilizando movimento rotatório contínuo ou reciprocante e duas substâncias irrigadoras: estudo in vitro
Resumo Introdução O preparo do canal radicular, em especial o terço apical, é fundamental para o sucesso da terapia endodôntica, pois abriga o forame radicular, local que comunica o endodonto com os tecidos perirradiculares. Objetivo A presente pesquisa avaliou a contaminação do terço apical após a instrumentação de canais radiculares em três c

6. Detection of potentially pathogenic bacteria on cell phones of hospital and university-based populations in Curitiba, southern Brazil. A cross-sectional study
ABSTRACT BACKGROUND: Cell phones have become indispensable for professional activities, including healthcare. Thus, they are possible sources of bacterial contamination. There is a scarcity of data in the literature regarding identification of risk factors for contamination of cell phones with pathogenic bacteria. OBJECTIVE: To compare the prevalence rat

7. Indoor Air Quality in the Hospital: The Influence of Heating, Ventilating and Conditioning Systems
Abstract Clean, fresh air is the most important requirement for good indoor air quality (IAQ) in all buildings, but it is especially important with regard to the environments within hospitals and other healthcare facilities. The literature indicates that buildings with heating, ventilating and air conditioning (HVAC) systems may have an increased risk of sic

8. In vitro culture and diversity of endophytic fungi in Bambusa oldhamii
RESUMO Bambusa oldhamii Munro é uma espécie de bambu lenhoso de crescimento rápido e com forte apelo comercial. No Brasil, o uso dessa espécie é limitado, devido, principalmente, à baixa disponibilidade de mudas para plantios comerciais. A micropropagação é uma técnica de produção de mudas em larga escala, porém, protocolos de estabelecimento de

11. The rates and players of denitrification, dissimilatory nitrate reduction to ammonia (DNRA) and anaerobic ammonia oxidation (anammox) in mangrove soils
Abstract Mangroves are ecosystems located in the transition zone between land and sea, characterized by periodic flooding that confer to its unique characteristics. Little is known about the transformation of nutrients that occur during the organic matter degradation in this system. In this study, we monitor the nitrogen transformations in soils from three m
