Efectos citotoxicos in vitro de extractos y fracciones de Bursera tomentosa (Jacq.) Triana & Planch., Burseraceae, frente a lineas celulares tumorales humanos

Actividad in vitro de retapamulina frente a cepas de Staphylococcus aureus resistente a meticilina y a linezolid RESUMEN

Resultados: Retapamulina inhibió todas las cepas de SASM and SARM alcanzando CMIs sobre 0,125 mg/L, pero las 18 cepas SARM-L se mostraron resistentes, con CMIs en torno a 32 mg/L. La mayoria de los aislados de SASM (9/10) fueron sensibles a mupirocina con CMIs inferiores a 0,19 mg/L, aunque entre las cepas de SARM tan solo fueron sensibles la mitad. La mayoría de las cepas SARM-L (17/18) fueron...

Secuencias Cifrantes de Números Metálicos a partir de Fracciones Contínuas

Extracción no supervisada de relaciones entre medicamentos y efectos adversos

In this work we present preliminary results obtained by a new unsupervised technique for extracting relations between drugs and adverse drug reactions. The identification of those relations is achieved using a knowledge representation model that generates pairs of entities and assigns them a specific weight, depending on the statistical significance of their co-occurrence in the same document. ...

Efectos de la Negación, Modificadores, Jergas, Abreviaturas y Emoticonos en el Análisis de Sentimiento

Some problems present in the treatment of opinions are: the use of informal, ironic and sarcastic language, abbreviations, orthographic and typographic mistakes, semantic compositionality, the cultural level and knowledge of language. These problems impose greater difficulty on opinion mining than on text mining in general. Therefore, the aim of our research is to develop computational solution...

Técnicas de robustez frente al ruido para sistemas de reconocimiento de habla en teléfonos móviles y PDAs

In recent years, speech recognition technology has reached a level of maturity to play an important role as a key component of conversational interfaces in many applications, including new services developed on portable devices with limited resources like mobile phones and Personal Digital Assistants (PDA). In this context, Automatic Speech Recognition (ASR) systems needs to meet two conditions...
