    La etiología del pie cavo cuando ésta es conocida, suele ser debida a un trastorno de tipo neurológico o miopático, aunque en determinados casos nos encontramos con pacientes que padecen esta deformidad en el pie, en los cuales no podemos descubrir ningún antecedente de este tipo, por lo que lo calificamos de pie cavo «esencial». A un grupo de estos pacientes con pie cavo «esencial», en los que no hemos encontrado ningún tipo de antecedente neurológico, lo hemos sometido a una exploración electroneurográfica, encontrando que la mitad de ellos padecían algún trastorno neuropático/miopático, que no había sido detectado en la exploración clínica inicial.Neurological or myopathic diseases are frequently involved in the etiology of flat foot. In some cases, no antecedents of disease can be found and therefore these flat foots are classified as «essential». We have undertaken an electrophysiologic study in a series of patients with «essential» flat food in order to explore unsuspected neurological disorders. In half of the patients, neuropathic and myopathic electroneurographic patterns of different severity were detected

    Las plantas medicinales, un recurso natural en áreas de montaña

    The mountain areas are, at the present time, due your isolated situation, places where are still using plants for curing human and animal diseases. In this work are related the developing of this areas with the explotation of ours natural resources, as crops or as picking. For this, and froro ours direct investigations in the Güéjar-Sierra town (Andalucía, Spain), are advocated for a interdisciplinary study for to obtain a developing of this potenciality.Las áreas de montaña son, en la actualidad, por su situación en cierta forma, más aislada del modo de vida moderno, lugares en que aún se practica de forma tradicional la medicina popular, fundamentalmente el uso de especies vegetales autóctonas. En nuestro trabajo abordamos la idea de que una utilización racional del territorio debe ir paralela con un aprovechamiento de estos recursos vegetales. Ya sea como simple recolección o como cultivos. Para ello, y a partir del estudio etnobotánico que hemos efectuado en el municipio de Güéjar-Sierra, abogamos por la investigación multidisciplinar como única forma de conseguir un desarrollo de la potencialidad natural del área

    Eliminating Error in the Chemical Abundance Scale for Extragalactic HII Regions

    Get PDF
    In an attempt to remove the systematic errors which have plagued the calibration of the HII region abundance sequence, we have theoretically modeled the extragalactic HII region sequence. We then used the theoretical spectra so generated in a double blind experiment to recover the chemical abundances using both the classical electron temperature + ionization correction factor technique, and the technique which depends on the use of strong emission lines (SELs) in the nebular spectrum to estimate the abundance of oxygen. We find a number of systematic trends, and we provide correction formulae which should remove systematic errors in the electron temperature + ionization correction factor technique. We also provide a critical evaluation of the various semi-empirical SEL techniques. Finally, we offer a scheme which should help to eliminate systematic errors in the SEL-derived chemical abundance scale for extragalactic HII regions.Comment: 24 pages, 9 Tables, 13 figures, accepted for publication in MNRAS.

    Heritability of Body Mass Index: A comparison between the Netherlands and Spain.

    Get PDF
    A high body mass index (BMI) is commonly used as an index of overweight and obesity. There is persistent evidence of high heritability for variation in BMI, but the effects of common environment appear inconsistent across different European countries. Our objective was to compare genetic and environmental effects on BMI in a sample of twins from two different European countries with distinct population and cultural backgrounds. We analysed data of adult female twins from the Netherlands Twin Register (222 monozygotic [MZ] and 103 dizygotic [DZ] pairs) and the Murcia Twin Register (Spain; 202 MZ and 235 DZ pairs). BMI was based on self-reported weight and height. Dutch women were taller and heavier, but Spanish women had a significantly higher mean BMI. The age related weight increase was significantly stronger in the Spanish sample. Genetic analyses showed that genetic factors are the main contributors to variation in height, weight, and BMI, within both countries. For height and weight, estimates of genetic variances did not differ, but for height, the estimate for the environmental variance was significantly larger in Spanish women. For BMI, both the genetic and the environmental variance components were larger in Spanish than in Dutch women

    Waist circumference percentiles for Hispanic-American children and comparison with other international references

    Introduction Waist circumference (WC) constitutes an indirect measurement of central obesity in children and adolescents. Objective To provide percentiles of WC for Hispanic-American children and adolescents, and compare them with other international references. Materials and methods The sample comprised 13 289 healthy children between 6 and 18 years coming from public schools of middle and low socioeconomic levels in different parts of Argentina, Cuba, Spain, Mexico, and Venezuela. The LMS method to calculate WC percentiles was applied. Sex and age differences were assessed using Student'sttest and ANOVA (SPSS v.21.0). Comparisons were established with references from the United States, Colombia, India, China, Australia, Kuwait, Germany, Tunisia, Greece, and Portugal. Results WC increases with age in both sexes. Boys show higher WC in P3, P50, and P97. Comparison of 50th and 90th percentiles among populations from diverse sociocultural and geographical contexts shows high variability, not all justified by the measurement method. Discussion and conclusions Specific WC percentiles for sex and age, and P90 cut-off points are provided; these values are potentially useful to assess central obesity in Hispanic-American adolescent children

    Genotype, environment and their interaction on olive

    Resumen del trabajo presentado en la 6th International Conference on the Olive Tree and Olive Products, celebrada en Sevilla (España) del 15 al 19 de octubre de 2018.The wide olive genetic patrimony has revealed high variability for most of the agronomic and oil quality traits of interest in olive growing. Few studies, however, have addressed the interaction of this variability with the environment, a subject of particular interest considering the natural high instability of the Mediterranean climate and the challenge of the predicted climate change. The current work presents results on the interaction between genotype and environment from multi-environment trials of olive cultivars and breeding selections, planted in different edaphoclimatic conditions of Andalusia, Southern Peninsular Spain and Canary Islands. For most of the agronomic and oil quality characters evaluated (flowering phenology, flower quality, pattern of oil accumulation, fatty acid composition and phenol content and composition), significant genotype and environment effects have been observed. For example, olive cultivars grown in Tenerife under much milder winter temperatures than in the Iberian Peninsula showed substantially earlierflowering and oil accumulation. Only in the case of flowering phenology was no significant genotype effect found. Furthermore, a strong genotype x environment effect was highly consistent in all characters considered. Regarding resistance to disease, such as Verticillium wilt, the variability of results from both natural and artificial inoculations also tends to indicate a considerable environmental effect and the need for careful testing of disease evolution. All this information strongly suggests the necessity of comparative trials of olive cultivars for both adequate choice of cultivar and final selection in breeding programs
