Diminishment of respiratory sinus arrhythmia foreshadows doxorubicin-induced cardiomyopathy.

BACKGROUND: The development of a microcomputer-based device permits quick, simple, and noninvasive quantification of the respiratory sinus arrhythmia (RSA) during quiet breathing. METHODS AND RESULTS: We prospectively and serially measured the radionuclide left ventricular ejection fraction and the RSA amplitude in 34 cancer patients receiving up to nine monthly bolus treatments with doxorubicin hydrochloride (60 mg/m2). Of the eight patients who ultimately developed symptomatic doxorubicin-induced congestive heart failure, seven (87.5%) demonstrated a significant decline in RSA amplitude; five of 26 subjects without clinical symptoms of cardiotoxicity (19.2%) showed a similar RSA amplitude decline. On average, significant RSA amplitude decline occurred 3 months before the last planned doxorubicin dose in patients destined to develop clinical congestive heart failure. CONCLUSION: Overall, RSA amplitude abnormality proved to be a more specific predictor of clinically significant congestive heart failure than did serial resting radionuclide ejection fractions.

Multicomponent gas-mixture measurements using an array of gas sensors and an artificial neural-network

An Electronic Nose is being jointly developed between the University of Greenwich and the Institute of Intelligent Machines to detect the gases given off from an oil filled transformer when it begins to break down. The gas sensors being used are very simple, consisting of a layer of Tin Oxide (SnO2) which is heated to approximately 640 K and the conductivity varies with the gas concentrations. Some of the shortcomings introduced by the commercial gas sensors available are being overcome by the use of an integrated array of gas sensors and the use of artificial neural networks which can be 'taught' to recognize when the gas contains several components. At present simulated results have achieved up to a 94% success rate of recognizing two component gases and future work will investigate alternative neural network configurations to maintain this success rate with practical measurements.

El papel de la memoria de trabajo en la adquisición lectora en niños de habla castellana.

Se propone plantear una investigación que analice las relaciones entre la adquisición lectora y la memoria de trabajo. Objetivos: A) Revisar las variables relacionadas con la manipulación de informacion y vinculadas al desarrollo de la capacidad lectora. B) Estudiar el papel de las variables en las primeras etapas lectoras y su evolución con la edad. C) Obtener resultados derivados de situaciones lo más naturales y próximas al niño. D) Alcanzar conclusiones con consecuencias prácticas en el campo educativo y en el aprendizaje de la lectura. 48 Sujetos de primero, tercero y quinto de EGB de tres colegios públicos se formaron 3 grupos (uno por cada nivel) de 16 sujetos con el mismo número de varones que de hembras y con el mismo número en los niveles lectores (alto y bajo). La selección respondió a dos criterios: A) Fueron excluidos los colegios públicos que no tenían condiciones adecuadas (espacio, colaboración del profesorado, etc.), B) Se agruparon los centros cuyos planteamientos pedagógicos y didácticos eran los más homogeneos posibles. Se utilizó un diseño factorial del tipo ANOVA de 2 (nivel lector: alto, bajo) x 3 (cursos: primero, tercero y quinto) X 5 (condiciones experimentales: 5 tareas a, b, c, d, e), sobre el tiempo medio de denominación de dibujos en las distintas condiciones experimentales. Para contrastar las hipótesis se han analizado experimentos distintos: A) Denominación de dibujos para contrastar efectos de interferencia y facilitación. B) Amplitud de memoria. C) Influencia de la actividad distractora que afecta de forma desigual según la edad y el nivel lector. D) La repetición no es una estrategia de uso más eficiente según la edad y el nivel lector. Tale. Matrices progesivas de Raven. 40 Dibujos de animales (material estimular de la investigación). Prueba de amplitud de memoria. Prueba de Brown-Peterson. Prueba de recuerdo libre. Ordenador Amstrad 64K Microcomputer. ANOVA factorial mixto 2 x 3 x (x) en el que los dos primeros factores (nivel lector, cursos) es intersujetos, y el último intrasujetos. Las medidas del tiempo de reacción se han elaborado con la mediana para eliminar el efecto de los tiempos extremos. La comparación entre los distintos cursos primero-tercero, primero-quinto y tercero quinto, se ha realizado a traves de la comparación de medias de grupo de Dunnbonferroni. Se parte del supuesto de que en estas primeras etapas del proceso lector se producen importantes cambios en la retención y manipulación de la memoria de trabajo. Los resultados lo confirman: las diferencias entre los distintos grupos de edad han sido en todos los casos significativas. Las máximas diferencias se han producido entre primero y tercero, siendo mínimas entre tercero y quinto curso. Se han constatado las grandes posibilidades de utilización de la 'prueba de denominación de dibujos' para la investigación básica y en el campo educativo.
