RESUMO
INTRODUCTION: The Drop foot is a condition that is usually handled with short orthosis, usually made of polypropylene. It has also been described as being treated with silicon orthosis, little studied but which seem to improve the kinematic pattern of gait and, given its comfort, be more accepted by patients. Our study describes the kinematic characteristics of gait and patient satisfaction when using a silicon foot ankle orthosis, and compares this pattern to the non-use of the orthosis, in patients with a drop foot. MATERIAL AND METHODS: Pseudo-experimental descriptive study in patients with dropped feet from 2010 to 2012, in which the kinematic variables of the gait pattern were evaluated from gait laboratories and in addition to the satisfaction of subjects with silicon orthosis and non-use of them. RESULTS: Five patients with a drop foot were the subject of the study. Gait analysis of patients using the orthosis found an improvement in ankle position at initial contact, average walking speed and step length, as well as increased cadence. However, in terms of comfort compared to the non-use of the orthosis, the result was meager. CONCLUSIONS: Silicon foot ankle orthosis improve the position of the ankle in the initial contact, as well as the temporo-spatial parameters of the gait.
INTRODUCCIÓN: El pie caído es una condición que suele manejarse con ortesis cortas, normalmente fabricadas en polipropileno. Se ha descrito también su tratamiento con ortesis de silicón, poco estudiadas pero que parecen mejorar el patrón cinemático de la marcha y, dada su comodidad, ser más aceptadas por los pacientes. Nuestro estudio describe cuáles son las características cinemáticas de la marcha y la satisfacción referida por los pacientes al usar una ortesis tobillo pie de silicón y compara dicho patrón con el no uso de la ortesis en casos con pie caído. MATERIAL Y MÉTODOS: Estudio seudoexperimental descriptivo en pacientes con pie caído desde el año 2010 al 2012, en el que se evaluaron las variables cinemáticas del patrón de marcha a partir de laboratorios de marcha y además de la satisfacción de los sujetos con las ortesis de silicón y con el no uso de las mismas. RESULTADOS: Cinco casos con pie caído fueron objeto del estudio. El análisis de marcha de los pacientes que usaron la ortesis constató una mejora de la posición del tobillo en el contacto inicial, en la velocidad promedio de marcha y en la longitud del paso, así como un aumento de la cadencia. Sin embargo, en términos de comodidad en comparación con el no uso de la ortesis, el resultado fue exiguo. CONCLUSIONES: Las ortesis tobillo pie de silicón mejoran la posición del tobillo en el contacto inicial, así como los parámetros temporoespaciales de la marcha.

In this work, the effect of different elicitors and culture conditions on the production of glucosinolates in broccoli cell cultures was studied. The results showed that 0.5 µM coronatine was the best elicitor for increasing glucosinolate production (205-fold increase over untreated cells after 72 h of treatment). Furthermore, the expression levels of some genes related to the biosynthetic pathway of glucosinolates as well as three Myb transcription factors also have been studied. The highest glucosinolate levels found in coronatine-treated cells were closely correlated with the highest gene expression levels of Cyp79b2, Cyp83b1, St5a, Myb51, and Myb122 after 6 h of treatment. The data shown in this study provide new insight into the key metabolic steps involved in the biosynthesis of glucosinolates, which will be of use for future applications of metabolic engineering techniques in broccoli.
