Objective: To analyze medium-term results in patients who underwent an open Bristow-Latarjet surgery considering the preoperative ISIS value. Methods: Retrospective study of 33 patients operated on between 2005 and 2012; average age: 33 years (range 21-68), median follow-up: 6 years (range 2-9). Results from Rowe and Constant scores, DASH questionnaire were registered and a subjective assessment of the result by each patient was also used. Results: No recurrence was reported. Mean Rowe score was 74.6 (range 15-100) and mean Constant score was 70 (range 32-98). The DASH questionnaire showed a mean value of 22.9 (range 0-73). Seventy-nine percent of patients were satisfied with the results. The migration of a screw occurred in one patient. There were no complications. Conclusions: We believe that Bristow-Latarjet technique is a reliable option, with few complications and a low recurrence rate to treat chronic shoulder instability as reported in literature. Therefore, we believe that it should be used as primary surgery in some cases and the preoperative ISIS scale is an excellent and simple guide to correctly select the surgical technique for each patient.

Objetivo: Analizar los resultados obtenidos a mediano plazo en los pacientes operados con la tecnica de Bristow-Latarjet, segun el valor del ISIS preoperatorio. Materiales y Métodos: Estudio retrospectivo de 33 pacientes intervenidos entre 2005 y 2012; media de la edad: 33 anos (rango 21-68); media del seguimiento 6 anos (rango 2-9). Se recogieron los resultados de las escalas de Rowe y Constant, el cuestionario DASH y una encuesta de valoracion subjetiva del resultado por parte de cada paciente. Resultados: No hubo recidivas. Los puntajes medios posoperatorios fueron 74,6 (rango 15-100) en la escala de Rowe y 70 (rango 32-98) en la escala de Constant. En el cuestionario DASH, el valor promedio fue 22,9 (rango 0-73). El 79% de los pacientes se mostraron satisfechos con el resultado. En un paciente, se produjo la migracion del tornillo, sin sintomas. No se identificaron otras complicaciones. Conclusiones: Consideramos, como esta reflejado en la literatura, que la tecnica de Bristow-Latarjet para tratar la inestabilidad glenohumeral anterior es una tecnica fiable, y con una tasa de recidivas baja, por lo que debe emplearse como cirugia de eleccion en determinados casos. Para ello, creemos que la valoracion preoperatoria con la escala ISIS es una buena guia a la hora de indicar el tipo de cirugia.

Zea mays L. híbridos (Buffalo, Falcão, H360 e HV313) foram tratados com ácido cítrico (2000 ppm). O rendimento de grãos, proteína solúvel e atividade proteolítica foram monitorados na fase de maturação fisiológica do cultivo. O ácido cítrico aplicado antes do aparecimento da folha bandeira induziu um aumento na produção de grãos 4222 a 5780 kg/ha, na proteína solúvel de 6.34 7.91 mg/mg de peso seco e atividade proteolítica de 14.3 to 65.7 µU mg prot-1, esto é, um incremento de 2-12 vezes nos híbridos Falcao, H360 e HV313, enquanto o híbrido Buffalo responderam com menor intensidade ao tratamento com ácido cítrico. No híbrido H360, tratadas com ácido cítrico, apresentou-se um aumento na atividade proteolítica de aspartil proteases e serin protease. Os resultados indicam que o ácido cítrico diferencialmente induz a atividade proteolítica e o vigor de híbridos de milho testados.

Hybrids of Zea mays L. (Buffalo, Falcon, H360 y HV313) were treated with citric acid (2000 ppm). Grain yield, soluble protein and proteolytic activity were monitored when the crop reached physiological maturity. Citric acid was applied before the appearance of the flag leaf, and induced an increase in the grain yield from 4222 to 5780 kg/ha, in the soluble protein from 6.34 to 7.91 mg/mg and into the proteolytic activity from 14.3 to 65.7 µU mg prot-1. This is an increase of 2 to 12 times in the Falcon, H360 and HV313 hybrids, while the Buffalo hybrid responded with less intensity to the treatment with citric acid. In the H360 hybrid treated with citric acid, an increase in the proteolytic activity of aspartyl serine proteases was observed. The results indicate that citric acid differentially induces proteolytic activity and vigor in the corn hybrids analyzed.

The annual cycle of marine cladocerans was studied over six years from 1994 to 1999 within the frame of the monitoring Project ECOMALAGA at a nine stations in the NW of the Alboran Sea, with the aim of assessing seasonal patterns and interannual trends in distribution and abundance of marine cladocerans. Seven species (Penilia avirostris, Evadne nordmanni, Evadne spinifera, Pseudoevadne tergestina, Pleopis polyphemoides, Podon leuckarti and Podon intermedius) were detected in the northwest Alboran Sea. Total cladoceran relative abundance varied from 0 to 89 % of the total cladocerans. The abundance of cladocerans was higher in summer-autumn than in winter-spring (7012 - 4711.100 and 743 - 217.100m-3 , respectively). The species composition was very different in terms of seasonality. P. polyphemoides, P. leuckarti and P. intermedius appeared mostly during the spring. P. tergestina, E. spinifera and E. nordmanni predominantly occurred during the winter. P. avirostris occurred mostly during the summer and autumn.
