We present an updated list of the polychaete species described for the Caribbean coasts of Colombia after a historical review of the literature. The taxonomic list includes references to the nomenclature, the synonymies, the data from the ecoregion, the habitat and the bathymetry. Based on the review, we were able to determine that up to September 2019, 51 families, 230 genera, and 293 species with scientific validity had been described for the Colombian Caribbean coast. Eunicidae is the family with the highest number of records, with a total of 33 (11.3%) species, followed by Syllidae with 23 species (7.8%) and Nereididae with 19 species (6.5%). The Tayrona ecoregion presented the greatest diversity, with 32% of species records, followed by the Magdalena ecoregion with 23.4%. Polychaetes in Colombia have been collected in natural habitats such as mangroves, seagrasses, and even as parasites and commensals of other organisms; however, about 60% of the taxonomic records correspond to organisms collected in soft and hard bottoms, mainly between 0 and 15 m deep. The descriptions and records of species on the Colombian Caribbean coast are due to the important contributions made in the 19th century by international and national researchers.
En la práctica clínica es importante que los instrumentos rotatorios estén estériles para evitar infecciones cruzadas. Objetivo: Evaluar la efectividad del proceso de esterilización de las limas primarias WaveOne® con el propósito de fundamentar su reutilización. Métodos: Se evaluaron 50 limas primarias WaveOne®, 10 nuevas y 40 usadas en conductos mesovestibulares de molares con diagnóstico de periodontitis apical y necrosis pulpar. Las limas usadas se esterilizaron mediante la prueba de esterilidad establecida por la farmacopea 35 europea y japonesa. Resultados: Las 10 limas WaveOne® primarias, sin uso, no mostraron crecimiento de microrganismos. En el grupo 2, las 40 limas WaveOne® primarias usadas una vez y esterilizadas tampoco mostraron crecimiento de microrganismos. Conclusiones: El proceso de esterilización de las limas primarias WaveOne® fue satisfactorio. Además, las limas primarias WaveOne®, como lo indica el fabricante, vienen estériles en su empaque. PALABRAS CLAVE Esterilización; limas rotatorias níquel titanio; WaveOne ÁREAS TEMÁTICAS Endodoncia; sistemas rotatorios ABSTRACT Background: It is important that rotary instruments used in clinical practice are sterile to avoid cross-infection. Objective: To evaluate the effectiveness of the sterilization process of Primary WaveOne® files, in order to support their reutilization. Methods: The sample consisted of 50 Primary WaveOne® files, 10 new and 40 used to prepare mesio-vestibular root canals of molars with diagnosis of pulp necrosis or apical periodontitis. Files in group 2 were sterilized and tested through the protocol described at the European and Japanese Pharmacopoeia 35. Results: The 10 new Primary WaveOne® files did not show microorganism growth. The 40 sterilized files of group 2 did not show growth of microorganisms either. Conclusions: The process of file sterilization was effective. In addition, WaveOne® Primary files, as indicated by the manufacturer, come in sterile packaging.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
