Abstract: the purpose of the present study was to compare dry matter yield and nutritive value of conventional hybrid grain sorghum [(sorghum bicolor (l.)] as influenced by row spacing, with conventional hybrid maize (zea mays l.). sorghum hybrid var. solarius was planted at two distances between rows, 75 and 20 cm, and maize var. anjou 387 at 75 cm (conventional planting). dry matter yield (dmy) in both species decreased over the years, being this fall greater in maize. dmy fell by 20.7, 6.5 and 5 t ha-1 in 2009 when compared to 2007 for maize, sorghum 75 and 20 cm, respectively, indicating that dmy in sorghum 20-cm was less affected by a drop in rainfall than in the other treatments. when averaged over the years, sorghum 20-cm showed the higher protein concentration, 104.1 g kg-1 ms vs 89.4 and 70.5 g kg-1 dm for sorghum 75-cm and maize, respectively. digestibility in maize was higher than in the average of the two sorghum treatments, 692 vs 636 g kg-1 dm, respectively. lignin concentration in maize was 18 vs 28.8 g kg-1 dm for the average of the two sorghum treatments. however, digestibility in both sorghum treatments increased by 77.2 g kg-1 ms from 2007 to 2009. maize was more sensitive to environmental variations. sorghum planted at 20 cm between rows shows both greater dmy and protein concentration than maize in dry matter yield when rainfall is a limiting factor.

Abstract: El objetivo fue comparar el rendimiento de materia seca (RMS) y la calidad de variedades de sorgo de grano y forrajero con o sin nervadura café (bmr), al emplear plantas con concentraciones promedio de 300 g kg-1 de MS. Se estudiaron tres variedades de grano (Solarius, Aralba y Topsilo) y tres forrajeras (Sweet Virginia, Big Kauna y Sucrosorgho). Sweet Virginia and Big Kahuna contienen el gen bmr. El RMS varió de 11.10 t, de Topsilo, a 17.12 t ha-1 de Sweet Virginia, relacionada con la altura de planta y con la proporción tallo/planta. Topsilo tuvo mayor número de rebrotes (1.5 m-1). La relación panícula/planta no fue diferente entre variedades. El número de plantas m-1 varió entre variedades pero no afectó el RMS. La concentración de proteína varió de 75.45 g kg-1 MS en Big Kahuna, a 104.3 g kg-1 MS en Solarius, y tuvo relación inversa con el RMS, con la altura de la planta y con la relación tallo/planta. Las variedades con mayor concentración de proteína (Solarius, Aralba y Topsilo), fueron las de menor RMS, menor altura y menor relación tallo/planta. El área foliar por planta fue la fuente de variación de la proteína entre las variedades de grano. La digestibilidad varió de 596 g kg-1 MS en Aralba, a 720.4 g kg-1 MS en Sweet Virginia, y estuvo relacionada con la concentración de lignina. Esta última variedad junto con Big Kahuna y Solarius fueron las de mayor digestibilidad. La alta digestibilidad de Solarius (no portador de bmr) se debió a su baja proporción (0.35) tallo/planta. La variedad Sweet Virginia es una importante opción en la alimentación animal dado a su elevado RMS y digestibilidad. Solarius tuvo bajo RMS, pero es útil cuando se requieren altos consumos de materia seca digestible por animal (vacas lecheras), además de contar con la mayor concentración de proteína.

Abstract: Objetivo: comparar la capacidad de penetración de un sellador de fisuras convencional con una resina fluida como sellador, en función del tipo de preparación de la fisura (realización o no de ameloplastía). Material y métodos: Se utilizaron 20 molares y premolares sanos y se dividieron en dos grupos, en función de la resina utilizada: Helioseal F (Vivadent), Tetric Flow (Vivadent). Cada grupo se subdividió a su vez en dos (fisura sin preparar o preparada con ameloplastía). Posteriormente la fisura fue grabada con ácido ortofosforico y una vez preparada se colocó la resina directamente. Una vez termociclados fueron seccionados longitudinalmente y se valoró microscópicamente la profundidad de la fisura y la penetración del sellador en la fisura. Se aplicaron el test de ANOVA y el de Shefle en el análisis de los datos. Resultados: El tipo de preparación y la resina influyen en la penetración del sellador. Así mismo el Tetric Flow con ameloplastia fue el grupo que mayor penetración de la fisura consiguió. Conclusiones: La realización de ameloplastía facilita la penetración del sellador en la fisura y el uso de resinas fluidas mejora esa capacidad de penetración.

Abstract: Justificación y objetivo: La mutilación genital femenina genera consecuencias psicológicas, sexuales, sociales y médicas a corto y largo plazo, es una práctica común en países no occidentales; sin embargo, a medida que las poblaciones se dispersan se está convirtiendo en un problema a tratar dondequiera que los grupos practicantes se establezcan. El objetivo de este trabajo es determinar el grado de conocimiento de médicos y enfermeras obstétricas sobre mutilación genital femenina, sus consecuencias y manejo clínico. Materiales y método: Se realizó un cuestionario compuesto por preguntas abiertas y cerradas, el cual se aplicó a 70 médicos y 30 enfermeras, entre octubre y noviembre de 2006, en cuatro hospitales nacionales de la Caja Costarricense de Seguro Social, específicamente: San Juan de Dios, México, de la Mujer, y Calderón Guardia. Resultados: El 81% respondió que conocía acerca de la mutilación genital femenina, sin embargo 63% ignoraba que la mutilación genital femenina puede producir complicaciones obstétricas y 97% dijo desconocer el método de deinfibulación. El 60% de los médicos manifestó no estar preparado para manejar un caso de mutilación genital femenina. Discusión: Se refleja falta de conocimiento sobre este tema, explicado porque no es un diagnóstico común en la práctica médica en Costa Rica. No obstante, el hecho de que estas poblaciones estén migrando a nuevos territorios y que sí se haya documentado este diagnóstico en el país, justifica la necesidad de mayor información al personal de salud, sobre todo en el posible manejo que se le daría a una de estas pacientes. En este sentido es relevante el papel de la educación médica continua. Background and aim: Nowadays, the short and long-term consequences in psychological, sexual, social and medical areas of female genital mutilation are known. It is a common practice in non occidental countries. However because of globalization and migration it has been a problem in different countries. In this context it is very important that the medical and nursing professionals have knowledge about its medical complications and management. The present study was undertaken to determine the knowledge of medical doctors and nurses regarding female genital mutilation, its possible medical consequences and its clinical management. Materials and method: A survey was made to 70 medical doctors and 30 nurses, at 4 national hospitals of the Costa Rican social security system, between October and November 2006. Result: 81% know about female genital mutilation, however 63% do not know about its obstetric compl

Abstract: the objective of this study was to evaluate the available variability in 21 brachiaria humidícola genotypes with respect to protein concentration and dry matter production, during the dry season of the year. the study was carried out during the march, april and may months of the years 2004 and 2005, with neither watering nor fertilising of the soil. three harvests were obtained per genotype each year, with a regrowth period that varied from 33 to 35 d between harvests. the experiment was established under a completely randomised design in a split split-plot arrangement. results showed an important among-genotype variability (p < 0.0001) for protein concentration within the year, that varied from 101.1 to 119.5 g kg-1 of ms, for the 26 160 and 26 413 genotypes, respectively. the 26 413 and 16 891 genotypes recorded the greatest protein concentrations although not significantly above (p > 0.05) those of the 679 genotype (commercial humidícola). moreover, protein concentration presented an important stability in the environment with no interaction with the year or the harvest date (p > 0.05). on the other hand, an inverse relationship was observed between protein concentration and dry matter production: for this reason, a decrease in protein concentration was observed in the harvest material with the greatest dry matter production. this decrease is explained through a decrease in the proportion of leaves in the total aerial biomass of the plant.
