Abstract: mexico has a vast gene pool of native bean germplasm. to make use of this pool, knowledge of the genotype's agronomic, commercial and nutritional quality traits is necessary. this study was conducted to characterize 65 native bean genotypes on the basis of their cooking and protein quality. color, shininess, shape and size were determined, as were cooking quality, content and in vitro digestibility of the protein. sixteen groups, or "types", were defined by seed coat color; most had shiny seed coats. the kidney shape prevailed in the accessions. a wide range in size (grain volume) was observed. this trait was directly related with weight (r= 0.96**). the genotypes had cooking times considered short, between 43 and 81 min. there were significant differences in broth thickness; solids were between 0.22% and 0.58%. the genotype with the largest grain and longest cooking time and thicker broth was cacahuate type. protein content varied from 16.0% (in ojo de cabra type) up to 26.9% (negro type). the in vitro digestibility of the protein was more than 84%. there was no association between protein content and in vitro digestibility. native bean germplasm exhibited wide variability in quality parameters, which can be used in selection of better varieties.

Revista de la Sociedad Espa?ola del Dolor , 2010,
Abstract: introduction: the aim of anaesthetic premedication is to reduce anxiety and stress prior to surgery. paediatric patients suffer even more anxiety due to fear of the unknown and the separation from parents. the need to find out a suitable way of administering premedication to paediatric patients without causing any more trauma is a challenge for the anaesthesiologist. objectives: the objective of the current study was to evaluate the efficacy, level of sedation and a way of accepting two different types of premedication for children: oral transmucosal fentanyl citrate (otfc) and oral midazolam dissolved in fruit juice. methods: in this study, 40 children who were going to be subjected to various types of surgery were randomised to receive otfc 10 μg/kg and midazolam 0.3 mg/kg 30 minutes before venipuncture. variables taken into account were: haemoglobin saturation from the beginning of premedication and inside the recovery room, way of accepting, level of sedation, child behaviour after separation from parents, venous puncture and anaesthetic induction, delay in wakening, need of post-surgical analgesia and appearance of secondary effects. results: results were compared using student?s t (p < 0.05) and there were significant differences in favour of the otfc group as far as the way of accepting a venous puncture was concerned. no differences in behaviour were observed after separation from parents and anaesthetic induction. there were no significant differences in haemoglobin saturation or secondary effects between both groups. conclusions: we believe that the use of otfc is safe, effective and a convenient way to premedicate a paediatric population, who will be undergoing a surgical procedure, with a reasonable degree of sedation which makes separation from their parents, venous catheterisation and anaesthetic induction easier.

Revista de la Sociedad Espa?ola del Dolor , 2010,
Abstract: Introducción: La premedicación anestésica está destinada a reducir la ansiedad y la respuesta al estrés que supone el período anterior a la intervención quirúrgica. El temor a lo desconocido, al dolor y la separación de los padres son elementos que se a aden a la ansiedad perioperatoria en la población pediátrica. La necesidad de encontrar una vía de administración idónea en ni os que no a ada más sufrimientos a los ya existentes, es un reto para los anestesiólogos. Objetivo: Los objetivos del presente estudio eran valorar la eficacia, el grado de sedación y el modo de aceptación de 2 modalidades de premedicación para ni os: citrato de fentanilo oral transmucoso (CFOT) y midazolam oral disuelto en zumo de fruta. Material y método: Se estudiaron 2 grupos aleatorizados de 40 ni os que iban a someterse a cirugía de diversas especialidades. Las dosis administradas fueron de 10 μg/kg de CFOT y 0,3 mg/kg de midazolam, administrados 30 minutos antes de la punciσn venosa. Las variables consideradas fueron: saturaciσn de hemoglobina desde el inicio de la premedicaciσn y en la sala de despertar, modo de aceptaciσn, grado de sedaciσn, actitud del niρo al separarlo de los padres, ante la punción venosa y ante la inducción anestésica, retraso en el despertar, requerimiento de analgesia postoperatoria, aparición de efectos secundarios. Resultados: Los resultados se compararon utilizando la t de Student (p < 0,05), y se obtuvieron diferencias significativas en el grado de aceptación favorable al grupo de CFOT, así como la actitud del ni o en la canalización venosa. No hubo diferencias en la separación de los padres y en la inducción anestésica. No se presentaron secundarismos significativos en ningún grupo, ni se apreció tampoco desaturación importante de hemoglobina tras la administración de la premedicación. Conclusiones: Creemos que el CFOT se nos plantea como una administración de premedicación segura, eficaz y cómoda para población pediátrica, que vaya a someterse a intervención quirúrgica, con un adecuado grado de sedación que facilita la separación de los padres, la canalización venosa y la inducción anestésica.

Abstract: sea surface current measurements and wind stress and sea surface temperature satellite data were used to study the effect of northerly wind events (tehuanos) on coastal dynamics in the gulf of tehuantepec, mexico. the winter 2005 observations show a significant change in the intensity and direction of surface currents during wind events, which is reflected in an increase in kinetic energy and negative relative vorticity. the analysis revealed that kinetic energy of the coastal current decreases (increases) in periods when there is absence (presence) of tehuano wind events, and that the relative vorticity has a tendency to positive values under low wind conditions and a tendency to negative values during high wind events. an asymmetric ocean response was observed due to wind stress forcing and the interaction between a persistent coastal current and offshore wind stress.

Abstract: Las víctimas de la violencia reciben apoyo por parte del Estado para obtener acompa amiento psicosocial y reparar el da o sufrido. A pesar de los innegables avances normativos materializados en el marco de la ley de víctimas, estas corren el riesgo de ser revictimizadas. El presente informe de investigación recurre a metodologías cualitativas y a la psicología jurídica para determinar las mejores prácticas en la orientación de los procesos de acompa amiento psicosocial a víctimas de la violencia. La población objeto de estudio se encuentra en el Departamento del Magdalena.

Abstract: Introducción: acompa ando al dolor están presentes otras funciones biológicamente importantes, no siempre bien reconocidas que suelen denominarse "co morbilidades", una de ellas es el sue o, aunque también se ha demostrado cierta concordancia entre el estado anímico y la nocicepción, siendo los dos estados de ánimo más estudiados y considerados como más relevantes en relación con el dolor crónico, la ansiedad y la depresión. Objetivo: el objetivo principal es evaluar la calidad del sue o en pacientes con dolor crónico no maligno (DCNM) tratados con opioides potentes. Y como objetivos secundarios: analizar la incidencia de ansiedad y depresión en estos pacientes así como comparar la calidad del sue o e incidencia de ansiedad-depresión con distintas variables: tipo de opioide, género, sexo y tipo de dolor. Material y métodos: se consideró como universo del estudio a pacientes con DCNM tratados con el mismo opioide potente durante, al menos, tres meses y que acudieron a la consulta de Unidad del Dolor entre septiembre de 2009 y marzo de 2010. Fueron excluidos pacientes menores de 18 a os, aquellos que no quisieron colaborar, diagnosticados de fibromialgia y los que estuvieran en tratamiento psiquiátrico. Como instrumento evaluador del sue o se utilizó el Cuestionario Oviedo de Sue o (COS) y para mensurar el grado de ansiedad-depresión empleamos el Test Hospitalario de Ansiedad y Depresión (HAD) en su valoración global. El análisis estadístico se realizó para las variables cualitativas mediante la χ2 de Pearson. Las variables cuantitativas se compararon con un test de Student. Los valores con un p-valor menor que 0,05 fueron aceptados como significativos (95% de intervalo de confianza). Se usó el paquete estadístico SPSS.15 para Windows. Resultados: en la evaluación de los trastornos del sue o se encontraron diferencias significativas según el tipo de opioide consumido, siendo el grupo tratado con hidromorfoma el que mejores resultados presentó en las tres subescalas analizadas: valoración subjetiva del COS, subescala objetiva del insomnio y los que menor cantidad de fármacos consumían para dormir. También encontramos diferencia en la incidencia de ansiedad/depresión, significativamente estadística, en función del tipo de opioide, siendo de nuevo el grupo tratado con hidromorfona el que menor incidencia de afectación psíquica presentaba. No encontramos diferencias significativas en los trastornos del sue o y en la prevalencia de ansiedad-depresión en función de las otras varables: tipo de dolor, o sexo. Conclusiones: en nuestro estudio los pacientes que cons

Abstract: In the present work, it is estimated the greenhouse gases (GHG, GEI in this paper) emissions in 2005 by the consumption and/or transformation of energy in Mexico. This document is not official, and it is used as reference the fuel consumption reported in the Balance Nacional de Energia 2005 published by the Secretaria de Energia. In this way, it is standardized the emission sources that will be used in the near future to estimated the official 2005 GHG Emissions Inventory. In order to solve the absence of own emission factors in Mexico, it is used the default global emission factors proposed by the Intergovernmental Panel for Climate Change. The Sectorial Method was used to estimate the GHG emissions taking in account the fuel consumption in each subsector considered in the energy sector. It was found that the transport and energy industries sectors had the most GHG emissions, and that Mexico as a non–industrialized country had lower per capita emissions that developed countries.
