1. Penetration of a resin-based filling material into lateral root canals and quality of obturation by different techniques
The aim of this study was to evaluate the penetration of a resin/polyester polymer-based material (Resilon Real Seal; SybronEndo Corp., Orange, USA) into simulated lateral canals, and the quality of obturations by different techniques. A total of 30 standardized simulated canals were divided into three groups according to the technique of obturation used: MS

2. Eficácia da guta-percha e Resilon na obturação de canais laterais usando técnica termomecânica
OBJETIVO: O objetivo do estudo foi avaliar a efetividade da guta-percha e Resilon no preenchimento de canais laterais nos terços cervical, médio e apical radicular quando utilizada a técnica termomecânica. MATERIAL E MÉTODO: Canais radiculares de dentes artificiais foram preparados utilizando um método padrão. Canais laterais foram confeccionados util

3. Influência de diferentes técnicas obturadoras na força de união de materiais obturadores à dentina intrarradicular / Influence of techniques obturation in bond strength of endodontic materials in dentin intrarradicular
Neste estudo avaliou-se, in vitro, por meio do teste de Push Out, a influência das técnicas obturadoras, condensação lateral, McSpadden modificada e sistema Beefill, na adesividade dos materiais obturadores em canais achatados. Foram utilizados 40 incisivos inferiores instrumentados com o sistema rotatório Hero de acordo com a técnica Free Tip (Pécora

4. In vitro analysis of thermocompaction time and gutta-percha type on quality of main canal and lateral canals filling
The aim of this study was to evaluate the quality of filling in main and lateral root canals performed with the McSpadden technique, regarding the time spent on the procedure and the type of gutta-percha employed. Fifty simulated root canals, made with six lateral canals placed two apiece in the cervical, middle and apical thirds of the root, were divided in

5. Estudo "in vitro" de metodos de aplicação de curativos intracanais de hidroxido de calcio nos tratamentos endodonticos
The purpose of this research was evaluate "in vitro" the different insertion methods of calcium hydroxide paste into root canais. One hundred and twenty blocks were made with c1ear plastic blocks simulating root canais with apicaI matrix diameters with 0,30 mm (with curves), 0,50 mm, 0,80 mm, 1,20 mm and 1,40 mm. The tested methods were: counterclock wise ro

6. Detection and Isolation of Novel Rhizopine-Catabolizing Bacteria from the Environment
Microbial rhizopine-catabolizing (Moc) activity was detected in serial dilutions of soil and rhizosphere washes. The activity observed generally ranged between 106 and 107 catabolic units per g, and the numbers of nonspecific culture-forming units were found to be approximately 10 times higher. A diverse set of 37 isolates was obtained by enrichment on scyll

7. Genotypic and Phenotypic Diversity of phlD-Containing Pseudomonas Strains Isolated from the Rhizosphere of Wheat
Production of 2,4-diacetylphloroglucinol (2,4-DAPG) in the rhizosphere by strains of fluorescent Pseudomonas spp. results in the suppression of root diseases caused by certain fungal plant pathogens. In this study, fluorescent Pseudomonas strains containing phlD, which is directly involved in the biosynthesis of 2,4-DAPG, were isolated from the rhizosphere o

8. Changes in Populations of Rhizosphere Bacteria Associated with Take-All Disease of Wheat
Take-all, caused by Gaeumannomyces graminis var. tritici, is one of the most important fungal diseases of wheat worldwide. Knowing that microbe-based suppression of the disease occurs in monoculture wheat fields following severe outbreaks of take-all, we analyzed the changes in rhizosphere bacterial communities following infection by the take-all pathogen.

9. Electrotonic loading of anisotropic cardiac monolayers by unexcitable cells depends on connexin type and expression level
Understanding how electrotonic loading of cardiomyocytes by unexcitable cells alters cardiac impulse conduction may be highly relevant to fibrotic heart disease. In this study, we optically mapped electrical propagation in confluent, aligned neonatal rat cardiac monolayers electrotonically loaded with cardiac fibroblasts, control human embryonic kidney (HEK-
